May 24, 2010

Dear Stockholder of Thomas Weisel Partners Group, Inc.:

You are cordially invited to attend the 2010 Annual Meeting of Stockholders of Thomas Weisel Partners Group, Inc. (which we refer to as the Annual Meeting) which will be held on Tuesday, June 22, 2010, at 8:00 a.m., Pacific time. Thomas Weisel Partners Group, Inc. (which we refer to as Thomas Weisel Partners) has entered into a merger agreement with Stifel Financial Corp. (which we refer to as Stifel). If the merger and the other transactions contemplated by the merger agreement are approved and consummated, Thomas Weisel Partners will become a wholly-owned subsidiary of Stifel and will no longer be a publicly held corporation. The Thomas Weisel Partners board of directors has unanimously determined that the merger and the merger agreement are advisable, and are fair to, and in the best interests of, Thomas Weisel Partners and its stockholders and has approved the merger agreement and the merger. The merger requires the approval of holders of a majority of the voting power of the outstanding shares of Thomas Weisel Partners common stock, par value $0.01 per share, and Thomas Weisel Partners special voting preferred stock, par value $0.01 per share, voting together as a single class, and we are asking you to vote to approve and adopt the merger agreement and approve the merger at the Annual Meeting. At the Annual Meeting, you will also be asked to vote on the election of Thomas Weisel Partners directors and other Annual Meeting matters. The election of Thomas Weisel Partners directors and approval of the proposals other than the approval and adoption of the merger agreement and approval of the merger are not a condition to the completion of the merger.

Holders of Thomas Weisel Partners common stock and the holder of the one share of Thomas Weisel Partners special voting preferred stock as of the close of business on April 30, 2010, will be entitled to vote at the Annual Meeting. Each share of Thomas Weisel Partners common stock is entitled to one vote for each matter to be voted on at the Annual Meeting. The share of Thomas Weisel Partners special voting preferred stock held by CIBC Mellon Trust Company, as trustee (which we refer to as the trustee), is entitled to cast a number of votes equal to the number of then-outstanding exchangeable shares of TWP Acquisition Company (Canada), Inc. (which we refer to as the exchangeable shares and, together with the shares of Thomas Weisel Partners common stock, we refer to as the Shares) on all matters on which Thomas Weisel Partners common stock is entitled to vote. The trustee will only cast a number of votes on such matters equal to the number of exchangeable shares as to which it has received a voting instruction card from the owners of record of the exchangeable shares (other than Thomas Weisel Partners and any person directly or indirectly controlled by or under common control with Thomas Weisel Partners) as of the record date. The holders of shares entitled to cast a majority of the total votes of the outstanding shares of Thomas Weisel Partners common stock and Thomas Weisel Partners special voting preferred stock on April 30, 2010, present in person or represented by proxy at the Annual Meeting and entitled to vote, will constitute a quorum at the Annual Meeting.

On April 30, 2010, there were 26,748,099 shares of Thomas Weisel Partners common stock outstanding held by approximately 124 stockholders of record and one share of Thomas Weisel Partners special voting preferred stock held by the trustee (representing 6,183,121 exchangeable shares entitled to give voting instructions and therefore entitled to 6,183,121 votes). Thomas Weisel Partners does not have cumulative voting, and, except with respect to the share of Thomas Weisel Partners special voting preferred stock as discussed in the section entitled “Proposal One: The Merger—Appraisal Rights” beginning on page 86 of the enclosed proxy statement/prospectus, there are no appraisal or dissenters’ rights associated with any of the matters scheduled for a vote at the Annual Meeting.

Upon completion of the merger, each share of Thomas Weisel Partners common stock will be converted into the right to receive 0.1364 shares of Stifel common stock. Based on the number of shares of Thomas Weisel

Partners common stock and Stifel common stock outstanding as of the record date, current Thomas Weisel Partners stockholders are expected to own approximately 12.6% of the outstanding common stock of Stifel (including Stifel common stock issuable in respect of any exchangeable shares of TWP Acquisition Company (Canada), Inc., but not including, in either case, any stock issuable in respect of restricted stock units outstanding after the merger) following the merger.

Assuming that the holders of the exchangeable shares approve an amendment to the articles of TWP Acquisition Company (Canada), Inc. to permit the exchangeable shares to remain outstanding (referred to as the “Exchangeable Share Amendment”), the exchangeable shares will not be converted into other securities as part of the merger. In that case, each exchangeable share will remain outstanding and become exchangeable for 0.1364 shares of Stifel common stock. In the event the Exchangeable Share Amendment is approved, at the effective time of the merger, the one outstanding share of Thomas Weisel Partners special voting preferred stock will be canceled and automatically converted into one share of Stifel special voting preferred stock. The one share of Stifel special voting preferred stock will entitle the holder to that number of votes equal to the number of shares of Stifel common stock issuable upon exchange of the exchangeable shares outstanding from time to time other than exchangeable shares held by Stifel or any person directly or indirectly controlled by or under common control of Stifel. Pursuant to the merger agreement, if the Exchangeable Share Amendment is not approved, Thomas Weisel Partners will take all actions necessary to (a) cause TWP Acquisition Company (Canada), Inc. to exercise its right to redeem all of the outstanding exchangeable shares or (b) acquire or cause TWP Holdings Company (Canada), ULC to acquire all of the outstanding exchangeable shares, and, as a result of the merger, holders of exchangeable shares would receive shares of Stifel common stock. For a more complete description of what holders of exchangeable shares will receive in the merger, see Annex C, entitled “Supplemental Information for the Holders of Exchangeable Shares.”

Stifel common stock is traded on the New York Stock Exchange, or the NYSE, under the symbol “SF”. Based on the closing price of Stifel common stock on the NYSE on April 23, 2010 of $55.74, the last trading day before public announcement of the merger agreement, the merger consideration represented approximately $7.6029 in value for each Thomas Weisel Partners share. Based on the closing price of Stifel common stock on April 30, 2010 of $57.33, the record date for holders of Thomas Weisel Partners common stock and the exchangeable shares to vote at the meeting, the merger consideration represented approximately $7.8197 in value for each Thomas Weisel Partners share.

Both Thomas Weisel Partners and Stifel are excited about this transaction because Thomas Weisel Partners and Stifel believe it will: (1) realize the benefits of the firms’ highly complementary investment banking and research platforms, where management believes there is relatively little overlap, including less than 10% overlap in research coverage; (2) accelerate Stifel’s investment banking business growth while providing scale and stability to Thomas Weisel Partners’ investment banking operations by expanding Stifel’s presence in key growth areas of the global economy, especially in Technology, Healthcare and Natural Resources, raising Stifel’s profile within the venture capital community, where Thomas Weisel Partners maintains key relationships, enhancing Stifel’s mergers and acquisitions advisory services and equities lead manager credentials and expanding the distribution of Thomas Weisel Partners’ capital markets offerings through Stifel’s Institutional Group and Global Wealth Management segments; (3) diversify the revenue stream and balance the revenue contribution between Stifel’s Global Wealth Management and its Institutional Group segments; (4) benefit from the complementary fit between Stifel’s Global Wealth Management and Thomas Weisel Partners’ asset management business; (5) realize benefits from the expansion of Stifel’s west coast market presence and the expansion of Stifel’s international capabilities via Thomas Weisel Partners’ Canadian operations, (6) utilize the skills and relationships of the combined senior management teams; and (7) realize benefits from operating cost efficiencies, which the companies believe will allow them to enhance profitability.

The Thomas Weisel Partners board of directors recommends that you vote FOR the proposal to approve and adopt the merger agreement and approve the merger and FOR each of the other proposals described in the accompanying proxy statement/prospectus. In addition, certain executive officers of Thomas Weisel Partners have agreed to vote their shares of Thomas Weisel Partners common stock and give voting instructions with respect to their exchangeable shares, representing in the aggregate approximately 15.8% of the voting power of the outstanding shares of Thomas Weisel Partners common

stock and Thomas Weisel Partners special voting preferred stock, FOR the proposal to approve and adopt the merger agreement and approve the merger.

Your vote is very important. Regardless of the number of shares you own or whether or not you plan to attend the Annual Meeting, it is important that your shares be represented and voted. Voting instructions are inside. Holders of exchangeable shares should refer to the voting instructions that are included in the Notice to Exchangeable Shareholders that accompanies this proxy statement/prospectus.

The obligations of Stifel and Thomas Weisel Partners to complete the merger are subject to several conditions set forth in the merger agreement and summarized in the accompanying proxy statement/prospectus. Important information about Stifel, Thomas Weisel Partners, the Annual Meeting, the merger agreement, the merger and the other proposals for consideration at the Annual Meeting is contained in or incorporated by reference into the accompanying proxy statement/prospectus. I urge you to read the entire document, including any documents incorporated by reference into the accompanying proxy statement/prospectus and its annexes, carefully and in their entirety.

QUESTIONS AND ANSWERS ABOUT THE MERGER AND ANNUAL MEETING

The following are some questions that you, as a Thomas Weisel Partners stockholder or holder of exchangeable shares, may have regarding the merger and the other matters being considered at Thomas Weisel Partners’ 2010 Annual Meeting of Stockholders, which is referred to as the Annual Meeting, and the answers to those questions. You are urged to carefully read this proxy statement/prospectus and the other documents referred to in this proxy statement/prospectus in their entirety because the information in this section does not provide all of the information that might be important to you with respect to the merger and the other matters being considered at the Annual Meeting. Additional important information is contained in the annexes to, and the documents incorporated by reference into, this proxy statement/prospectus. In this proxy statement/prospectus, unless stated to the contrary or the context requires otherwise, the terms the “Company,” “we,” “our,” “ours,” and “us” refer to Thomas Weisel Partners and its subsidiaries.

Q:	*Why am I receiving this proxy statement/prospectus?*

Stifel and Thomas Weisel Partners have agreed to a merger. Under the terms of the merger agreement that is described in this proxy statement/prospectus, Thomas Weisel Partners will become a wholly-owned subsidiary of Stifel and will no longer be a publicly held corporation. See “Proposal One: The Merger” and “The Merger Agreement.” A copy of the merger agreement is attached to this proxy statement/prospectus as Annex A. This proxy statement/prospectus contains important information about Stifel, Thomas Weisel Partners, the Annual Meeting, the merger agreement, the merger and the other proposals for consideration at the Annual Meeting. This document is being delivered to you as both a proxy statement of Thomas Weisel Partners and a prospectus of Stifel in connection with the merger. It is the proxy statement by which the Thomas Weisel Partners board of directors is soliciting proxies from you to vote on the approval and adoption of the merger agreement and the approval of the merger and the other matters to be voted on at Thomas Weisel Partners’ Annual Meeting or at any adjournment or postponement of the Annual Meeting. It is also the prospectus pursuant to which Stifel will issue (or reserve for issuance) Stifel common stock to you in the merger.

You are receiving this proxy statement/prospectus because you have been identified as a stockholder of Thomas Weisel Partners and may be entitled to vote at the upcoming Annual Meeting or you hold exchangeable shares and may be entitled to instruct the holder of the Thomas Weisel Partners special voting preferred stock how to vote at the upcoming Annual Meeting. To complete the merger, the holders of a majority of the voting power of the outstanding shares of Thomas Weisel Partners common stock and Thomas Weisel Partners special voting preferred stock, voting together as a single class, must vote to approve and adopt the merger agreement and approve the merger, and all other conditions to the merger must be satisfied or waived. You should read this proxy statement/prospectus carefully.

Q:	*What will happen in the proposed merger?*

In the merger, Merger Sub, a wholly-owned subsidiary of Stifel, will merge with and into Thomas Weisel Partners. As a result, Thomas Weisel Partners will become a wholly-owned subsidiary of Stifel and will no longer be a publicly held corporation. See “Proposal One: The Merger—Structure of the Merger.”

Q:	*Why are Stifel and Thomas Weisel Partners proposing to merge?*

Stifel and Thomas Weisel Partners are proposing to merge because they believe that the complementary strengths of their two companies make a combination compelling and in the best interests of each company and our respective stockholders, clients and employees. Stifel and Thomas Weisel Partners believe the combination of Stifel and Thomas Weisel Partners will:

•

realize the benefits of the firms’ highly complementary investment banking and research platforms, where management believes there is relatively little overlap, including less than 10% overlap in research coverage;

•

accelerate Stifel’s investment banking business growth, while providing scale and stability to Thomas Weisel Partners’ investment banking operations, by:

•

expanding Stifel’s presence in key growth areas of the global economy, particularly in Technology, Healthcare and Natural Resources;

•

raising Stifel’s profile within the venture capital community, where Thomas Weisel Partners maintains key relationships;

•

enhancing Stifel’s mergers and acquisitions advisory services and equities lead manager credentials; and

•

expanding the distribution of Thomas Weisel Partners’ capital markets offerings through Stifel’s Institutional Group and Global Wealth Management segments;

•

diversify the revenue stream and balance the revenue contribution between Stifel’s Global Wealth Management and its Institutional Group segments;

•

benefit from the complementary fit between Stifel’s Global Wealth Management and Thomas Weisel Partners’ asset management business in a natural and complementary way;

•

realize benefits from the expansion of Stifel’s west coast market presence and the expansion of Stifel’s international capabilities via Thomas Weisel Partners’ Canadian operations;

•

utilize the skills and relationships of the combined senior management teams; and

•

realize benefits from operating cost efficiencies, which the companies believe will allow them to enhance profitability.

Please see page 70 of this proxy statement/prospectus for the factors considered by the Thomas Weisel Partners board of directors in recommending that Thomas Weisel Partners stockholders vote FOR the proposal to approve and adopt the merger agreement and approve the merger. Please see page 80 of this proxy statement/prospectus for Stifel’s reasons for the merger.

Q:	*What will I receive in the merger?*

If the merger agreement is approved and adopted and the merger is approved by Thomas Weisel Partners stockholders and the merger is completed, you will receive 0.1364 shares of Stifel common stock in exchange for each share of Thomas Weisel Partners common stock that you own. The holder of the one share of Thomas Weisel Partners special voting preferred stock will receive one share of Stifel special voting preferred stock, which will have substantially the same rights and privileges as the Thomas Weisel Partners special voting preferred stock (except that the issuer thereof will be Stifel rather than Thomas Weisel Partners and the voting rights applicable thereto shall apply to Stifel common stock rather than Thomas Weisel Partners common stock).

If you are a Thomas Weisel Partners stockholder, you will not receive fractional shares of Stifel common stock. Instead, you will receive the cash value, without interest, of any fractional share of Stifel common stock that you might otherwise have been entitled to receive, based on the 10-day average closing price for Stifel common stock ending on the second complete trading day prior to the closing date of the merger.

Q:	*What will holders of exchangeable shares of Thomas Weisel Partners’ Canadian subsidiary, TWP Acquisition Company (Canada), Inc., receive in the merger?*

one outstanding share of Thomas Weisel Partners special voting preferred stock will be canceled and automatically converted into one share of Stifel special voting preferred stock. The one share of Stifel special voting preferred stock will entitle the holder to that number of votes equal to the number of shares of Stifel common stock issuable upon exchange of the exchangeable shares outstanding from time to time other than exchangeable shares held by Stifel or any person directly or indirectly controlled by or under common control of Stifel. Pursuant to the merger agreement, if the Exchangeable Share Amendment is not approved, Thomas Weisel Partners will take all actions necessary to (a) cause TWP Acquisition Company (Canada), Inc. to exercise its right to redeem all of the outstanding exchangeable shares or (b) acquire or cause TWP Holdings Company (Canada), ULC to acquire all of the outstanding exchangeable shares, and, as a result of the merger, holders of exchangeable shares would receive shares of Stifel common stock. For a further description of what holders of exchangeable shares will receive in the merger, see Annex C, entitled “Supplemental Information for the Holders of Exchangeable Shares.”

Q:	*How will the merger affect stock options to acquire Thomas Weisel Partners common stock, other equity awards and the warrant?*

At the effective time of the merger, each Thomas Weisel Partners restricted stock unit award will be converted into the right to receive a number of shares of Stifel common stock equal to the number of shares of Thomas Weisel Partners common stock subject to such award multiplied by the exchange ratio. Following the effective time of the merger, each restricted stock unit will continue to be governed by the same terms and conditions, including any vesting requirements, as were applicable prior to the merger. At the effective time of the merger, all outstanding Thomas Weisel Partners stock options will be converted into the right to acquire a number of shares of Stifel common stock equal to the number of shares of Thomas Weisel Partners common stock subject to such award multiplied by the exchange ratio, and the exercise price of the award will equal the exercise price per share of Thomas Weisel Partners common stock applicable to such award divided by the exchange ratio. Following the effective time of the merger, each stock option will continue to be governed by the same terms and conditions, including any vesting requirements, as were applicable prior to the merger.

At the effective time of the merger, the outstanding Thomas Weisel Partners warrant will be converted into the right to purchase and receive a number of shares of Stifel common stock equal to the number of shares of Thomas Weisel Partners common stock subject to the warrant multiplied by the exchange ratio, and the exercise price of the warrant will equal the exercise price per share of Thomas Weisel Partners common stock of such warrant divided by the exchange ratio.

Q:	*When do you expect the merger to be completed?*

Stifel and Thomas Weisel Partners are working toward completing the merger as quickly as possible. The merger is expected to close on or around June 30, 2010, subject to receipt of Thomas Weisel Partners stockholder approval, governmental and regulatory approvals and other usual and customary closing conditions. However, no assurance can be given as to when, or if, the merger will occur.

Q:	*Are there conditions to completing the merger?*

A:	Yes. Stifel and Thomas Weisel Partners’ respective obligations to complete the merger are subject to the satisfaction or waiver of certain specified closing conditions. See “The Merger Agreement—Conditions to Complete the Merger.”

Q:	*What happens if the merger is not completed?*

If the merger agreement is not approved and adopted by Thomas Weisel Partners stockholders or if the merger is not completed for any other reason, you will not receive any payment for your shares of Thomas Weisel Partners common stock or Thomas Weisel Partners special voting preferred stock in connection with

the merger. Instead, Thomas Weisel Partners will remain an independent public company and its common stock will continue to be listed and traded on the Nasdaq Global Market. If the merger agreement is terminated under specified circumstances, Thomas Weisel Partners may be required to pay Stifel a termination fee of $10,000,000 as described under “The Merger Agreement—Expenses and Fees—Termination Fees Payable by Thomas Weisel Partners” beginning on page 102.

Q:	*Am I entitled to appraisal rights?*

Holders of Thomas Weisel Partners common stock are not entitled to appraisal rights under the Delaware General Corporation Law in connection with the merger. The holder of the share of Thomas Weisel Partners special voting preferred stock may have appraisal rights under certain conditions and should refer to Annex D for a summary of appraisal rights procedures relating to the Thomas Weisel Partners special voting preferred stock.

Q:	*What are the tax consequences of the merger to me?*

The merger is intended to constitute a reorganization for United States federal income tax purposes. If so treated, the exchange of your shares of Thomas Weisel Partners common stock for shares of Stifel common stock generally will not cause you to recognize gain or loss for U.S. federal income tax purposes. However, you will recognize income or gain with respect to cash received instead of any fractional shares of Stifel common stock. It is a condition to the merger that Stifel and Thomas Weisel Partners receive legal opinions to the effect that the merger constitutes such a reorganization for United States federal income tax purposes. These opinions will not bind the Internal Revenue Service, which could take a different view. To review the tax consequences to stockholders in greater detail, see “Material United States Federal Income Tax Consequences of the Merger” beginning on page 146.

The consequences of the merger to any particular stockholder will depend on that stockholder’s particular facts and circumstances. Accordingly, you are urged to consult your own tax advisor to determine your own tax consequences from the merger.

Holders of exchangeable shares should refer to Annex C for a summary of material Canadian federal income tax considerations.

Q:	*Are there any risks related to the proposed transaction or any risks related to owning Stifel common stock?*

A:	Yes. You should carefully review the risk factors beginning on page 43.

Q:	*What stockholder approvals are required for the merger?*

To approve and adopt the merger agreement and approve the merger, the holders of a majority of the voting power of the outstanding shares of Thomas Weisel Partners common stock and Thomas Weisel Partners special voting preferred stock, voting together as a single class, must vote “FOR” the approval and adoption of the merger agreement and the approval of the merger. Only holders of record of Thomas Weisel Partners common stock and the one share of Thomas Weisel Partners special voting preferred stock at the close of business on April 30, 2010, referred to in this proxy statement/prospectus as the “record date,” are entitled to notice of and to vote at the Annual Meeting. As of the record date, there were 26,748,099 shares of Thomas Weisel Partners common stock and one share of Thomas Weisel Partners special voting preferred stock held by the trustee (representing 6,183,121 exchangeable shares entitled to give voting instructions and therefore entitled to 6,183,121 votes) outstanding and entitled to vote at the Annual Meeting. Failure to vote your shares, abstentions and broker non-votes will have the same effect as voting against the proposal to approve and adopt the merger agreement and approve the merger. See “The Thomas Weisel Partners Annual Meeting—Quorum; Vote Required; Abstentions; Shares Held in Street Name.” The election of Thomas Weisel Partners directors and approval of the proposals other than the approval and adoption of the merger agreement and approval of the merger are not a condition to the completion of the merger.

If you hold exchangeable shares of TWP Acquisition Company (Canada), Inc. as of the record date and you wish to direct the trustee to cast the votes represented by your exchangeable shares attached to the Thomas Weisel Partners special voting preferred stock, you should follow carefully the voting instructions that are included in the Notice to Exchangeable Shareholders that accompanies this proxy statement/prospectus. The procedure for instructing the trustee differs in certain respects from the procedure for delivering a proxy, including the place for depositing the instruction and the manner of revoking the instruction.

Q:	What stockholder approvals are required for the adjournment of the Annual Meeting, if necessary, for any purpose, including to solicit additional proxies in favor of the approval and adoption of the merger agreement and the approval of the merger?

A majority of the votes cast “FOR” or “AGAINST” the adjournment of the Annual Meeting, if necessary, for any purpose, including to solicit additional proxies in favor of the approval and adoption of the merger agreement and the approval of the merger must be voted “FOR” such proposal for it to pass. Abstentions are not treated as a vote “FOR” or “AGAINST,” and will have no effect on the outcome of the vote on any proposal to adjourn the Annual Meeting. See “The Thomas Weisel Partners Annual Meeting—Quorum; Vote Required; Abstentions.”

Q:	*What do I need to do now?*

Please carefully review this proxy statement/prospectus and vote the proxy card or voting instruction card you receive as soon as possible. Your proxy card or voting instruction card must be received, or you must vote using the telephone or the Internet if available, no later than 11:59 p.m., Eastern time, on June 21, 2010 in order for your shares to be voted at the Annual Meeting, unless you attend and vote at the Annual Meeting.

Q:	*How does the Thomas Weisel Partners board of directors recommend I vote on the merger and adjournment proposals?*

After careful consideration, the Thomas Weisel Partners board of directors unanimously determined that the merger and the merger agreement are advisable, and are fair to, and in the best interests of, Thomas Weisel Partners and its stockholders and approved the merger agreement and the merger. Accordingly, the Thomas Weisel Partners board of directors recommends that you vote FOR the proposal to approve and adopt the merger agreement and approve the merger and FOR the adjournment of the Annual Meeting, if necessary, for any purpose, including to solicit additional proxies in favor of the approval and adoption of the merger agreement and the approval of the merger. See “Proposal One: The Merger—Thomas Weisel Partners’ Reasons for the Merger; Recommendation of the Thomas Weisel Partners Board of Directors.”

Q:	*Why is it important for me to vote?*

Thomas Weisel Partners and Stifel cannot complete the merger without the approval of holders of a majority of the voting power of the outstanding shares of Thomas Weisel Partners common stock and Thomas Weisel Partners special voting preferred stock, voting together as a single class. Therefore, any shares that are not voted will have the same effect as a vote “AGAINST” the merger.

Q:	*Have any Thomas Weisel Partners stockholders agreed to vote FOR the merger agreement and the merger?*

A:	Yes. Thomas Weisel, Chairman and Chief Executive Officer, Lionel P. Conacher, former President and Chief Operating Officer, Thomas Carbeau, Head of Institutional Sales, Richard Gay, Head of Research,

William McLeod, Co-Head of Investment Banking, Brad Raymond, Co-Head of Investment Banking, Paul Slivon, Chairman of Wealth Management, Anthony Stais, Head of Trading, and Shaugn Stanley, Chief Administrative Officer have agreed to vote their shares of Thomas Weisel Partners common stock and give voting instructions with respect to their exchangeable shares, representing in the aggregate, as of the record date, approximately 15.8% of the voting power of the outstanding shares of Thomas Weisel Partners common stock and Thomas Weisel Partners special voting preferred stock, FOR the proposal to approve and adopt the merger agreement and approve the merger.

Q:	*Do I need to send in my Thomas Weisel Partners stock certificates now?*

A:	No. If the merger is consummated, instructions will be sent to you regarding the exchange of your Thomas Weisel Partners stock certificates for the merger consideration payable to you in the merger.

Q:	*When and where will the Thomas Weisel Partners Annual Meeting be held?*

A:	The Annual Meeting will take place on June 22, 2010, at One Montgomery Street, 35^th Floor, San Francisco, California, commencing at 8:00 a.m., Pacific time.

Q:	*What matters will be voted on at the Annual Meeting?*

A:	You will be asked to vote on the following proposals:

•

To approve and adopt the merger agreement and approve the merger contemplated by the merger agreement;

•

To ratify the appointment of Deloitte & Touche LLP as Thomas Weisel Partners’ independent registered accounting firm for 2010; and

•

To conduct any other business that properly comes before the Annual Meeting or any adjournment or postponement of the Annual Meeting.

Q:	*What vote is needed for each proposal?*

A:	The following are the vote requirements for the various proposals:

•

Election of Directors. You may vote “FOR” or “WITHHOLD” with respect to any or all director nominees. The election of a director requires a plurality of the votes that are cast “FOR” the election of directors. Accordingly, the eight nominees receiving the highest number of “FOR” (among votes properly cast in person or by proxy and entitled to vote) will be elected. A properly executed proxy marked “WITHHOLD” with respect to the election of one or more directors will not be voted with respect to the director or directors indicated, and because there are eight nominees for eight director positions, “WITHHOLD” votes will have no effect on the outcome of the vote for the election of directors.

•

All Other Matters. You may vote “FOR,” “AGAINST” or “ABSTAIN” with respect to all other matters at the Annual Meeting. A majority of the votes cast “FOR” or “AGAINST” each other matter must be voted “FOR” such matter for it to pass. Abstentions are not treated as a vote “FOR” or “AGAINST” a proposal and will have no effect on the outcome of the vote for such proposal.

Q:	*Who are the director nominees?*

The eight director nominees are Thomas W. Weisel, Thomas I.A. Allen, Matthew R. Barger, Michael W. Brown, Robert E. Grady, B. Kipling Hagopian, Alton F. Irby III and Timothy A. Koogle. Each of the eight nominees is currently a member of the Thomas Weisel Partners board of directors and has been recommended for election to the Thomas Weisel Partners board of directors by Thomas Weisel Partners’ Corporate Governance and Nominations Committee and approved and nominated for election by the Thomas Weisel Partners board of directors. See “Proposal Three—Election of Directors.”

Q:	*How does the Thomas Weisel Partners board of directors recommend that I vote with respect to the election of directors?*

A:	The Thomas Weisel Partners board of directors unanimously recommends that you vote FOR the election of each of the nominated directors. See “Proposal Three—Election of Directors.”

Q:	*As a Thomas Weisel Partners stockholder, why am I electing Thomas Weisel Partners’ directors when I am being asked to approve and adopt the merger agreement and approve the merger?*

Delaware law requires Thomas Weisel Partners to hold a meeting of its stockholders each year. Thomas Weisel Partners has determined that it will observe this requirement and hold the meeting to elect directors to the Thomas Weisel Partners board of directors such that the directors elected at the Annual Meeting will serve as directors of Thomas Weisel Partners following the Annual Meeting through the earliest of Thomas Weisel Partners’ 2011 annual meeting of stockholders, his or her removal or resignation or, if the merger is completed, the effective time of the merger. Upon completion of the merger, the individuals serving as Thomas Weisel Partners directors immediately prior to the completion of the merger are expected to resign and will be replaced by designees of Stifel, although some of the current Thomas Weisel Partners directors may be nominated to become members of Stifel’s board of directors. See “Proposal One: The Merger—Board of Directors and Executive Officers of Stifel Following the Merger.”

Q:	*Who can vote at the Annual Meeting?*

A:	Thomas Weisel Partners stockholders of record at the close of business on the record date are entitled to vote at the Annual Meeting.

Q:	*What if I own exchangeable shares?*

Voting instructions for directing the trustee to cast the votes represented by your exchangeable shares, as well as instructions for attending the Annual Meeting if you hold exchangeable shares, are included in the Notice to Exchangeable Shareholders that accompanies this proxy statement/prospectus. The procedure for instructing the trustee differs in certain respects from the procedure for delivering a proxy, including the place for depositing the instruction and the manner of revoking the instruction. If you do not provide voting instructions for your exchangeable shares, they cannot be voted by the trustee and will not be counted for any purposes, including for determining the presence or absence of a quorum for the transaction of business.

Q:	*What is the record date for the Annual Meeting?*

A:	The record date for the Annual Meeting is April 30, 2010.

Q:	*What constitutes a quorum for purposes of the Annual Meeting?*

The holders of shares entitled to cast a majority of the total votes of the outstanding shares of Thomas Weisel Partners common stock and Thomas Weisel Partners special voting preferred stock on April 30, 2010, the record date, present in person or represented by proxy at the Annual Meeting and entitled to vote, will constitute a quorum for the transaction of business at the Annual Meeting. Withheld votes, abstentions and “broker non-votes” are counted for purposes of determining the presence or absence of a quorum for the transaction of business.

Q:	*How can I vote?*

If you are a stockholder of record, you may submit a proxy for the Annual Meeting by: (1) completing, signing, dating and returning the proxy card in the pre-addressed envelope provided; (2) using the telephone; or (3) using the Internet. For specific instructions on how to use the telephone or the Internet to submit a proxy for the Annual Meeting, please refer to the instructions on your proxy card.

If you hold your shares of Thomas Weisel Partners common stock or exchangeable shares in a stock brokerage account or if your shares are held by a bank or nominee (i.e., in “street name”), you must provide the stockholder of record of your shares with instructions on how to vote your shares. Please check the voting instruction card used by your broker or nominee to see if you may use the telephone or the Internet to provide instructions on how to vote your shares.

If you are a stockholder of record, you may also vote in person at the Annual Meeting. If you hold shares in a stock brokerage account or if your shares are held by a bank or nominee (i.e., in “street name”), you may not vote in person at the Annual Meeting unless you obtain a signed proxy from the stockholder of record giving you the right to vote the shares. You will also need to present photo identification and comply with the other procedures described in “The Thomas Weisel Partners Annual Meeting—Date, Time and Place; Attending the Annual Meeting” on page 61. Giving a proxy will not affect your right to vote your Thomas Weisel Partners shares if you attend the Annual Meeting and want to vote in person.

Q:	*What is the difference between holding shares as a stockholder of record and as a beneficial owner?*

A:	Many Thomas Weisel Partners stockholders hold their shares through a broker, bank or other nominee rather than directly in their own name. There are some important distinctions between shares held of record and shares beneficially owned.

Stockholder of Record: If your shares are registered directly in your name with Thomas Weisel Partners’ transfer agent, you are considered the stockholder of record with respect to those shares and this proxy statement/prospectus is being sent directly to you by Thomas Weisel Partners. As a stockholder of record, you have the right to grant your proxy directly to Thomas Weisel Partners or to vote in person at the Annual Meeting. Thomas Weisel Partners has enclosed a proxy card for your use.

Beneficial Owner: If your shares are held in a brokerage account, bank account or by another nominee, you are considered the beneficial owner of shares held in “street name,” and this proxy statement/prospectus is being forwarded to you by your broker, bank or nominee together with a voting instruction card. As the beneficial owner, you have the right to direct your broker, bank or other nominee how to vote and are also invited to attend the Annual Meeting. However, since you are not the stockholder of record, you may not vote your shares in person at the Annual Meeting unless you obtain a legal proxy from the broker, bank or nominee that holds your shares, giving you the right to vote the shares instead of the broker, bank or nominee holding your shares. Your broker, bank or nominee has enclosed voting instructions for your use in directing your broker, bank or nominee how to vote your shares.

Q:	*What do I do if I receive more than one proxy statement/prospectus or set of voting instructions?*

If you hold shares directly as a stockholder of record and also in “street name,” or otherwise through a nominee, you may receive more than one proxy statement/prospectus and/or set of voting instructions relating to the meeting. These should each be voted and/or returned separately in order to ensure that all of your shares are voted.

Q:	*What happens if I don’t indicate how to vote on my proxy card?*

A:	If you sign and send in your proxy card and do not indicate how you want to vote, your proxy will be counted voted as the Thomas Weisel Partners board of directors recommends, which is:

•

FOR the approval and adoption of the merger agreement and approval of the merger;

•

FOR the approval of the adjournment of the meeting, if necessary, for any purpose, including to solicit additional proxies if there are not sufficient votes to approve and adopt the merger agreement and approve the merger;

•

FOR the election to the Thomas Weisel Partners board of directors of each of the nominees for director named in this proxy statement/prospectus; and

•

FOR the ratification of the appointment of Deloitte & Touche LLP as Thomas Weisel Partners’ independent auditors for 2010.

Q:	*What happens if I do not vote?*

If you do not sign and send in your proxy card, vote using the telephone or the Internet or vote at the Annual Meeting, or submit voting instructions, as applicable, it will have the effect of a vote against the approval and adoption of the merger agreement and approval of the merger, but it will not affect all other proposals, including the election of directors, the adjournment proposal and the proposal to ratify the appointment of the independent registered public accounting firm. See “The Annual Meeting—Quorum; Required Votes; Abstentions; Shares Held in Street Name.”

Q:	*What happens if I abstain?*

Abstentions are counted as present and entitled to vote for purposes of determining a quorum. For the proposal to approve and adopt the merger agreement and approve the merger, abstentions have the same effect as a vote against the merger. If you abstain from voting with respect to the other proposals, including the election of directors, the adjournment proposal and the proposal to ratify the appointment of the independent registered public accounting firm, you will effectively not vote on that matter at the meeting. Abstentions are not considered to be votes cast under the Thomas Weisel Partners bylaws or under the laws of Delaware (Thomas Weisel Partners’ state of incorporation) and will have no effect on the outcome of the vote for any proposals other than the proposal to approve and adopt the merger agreement and approve the merger.

Q:	*If my shares are held in “street name” by my broker, will my broker automatically vote my shares for me?*

No. If your shares are held in an account at a broker, you must instruct the broker on how to vote your shares. If you do not provide voting instructions to your broker, your shares will not be voted on any proposal on which your broker does not have discretionary authority to vote. This is called a broker non-vote. In these cases, the broker can register your shares as being present at the meeting for purposes of determining the presence of a quorum but will not be able to vote on those matters for which specific authorization is required. Under the current rules of the NYSE, we believe that brokers do not have discretionary authority to vote on the proposal to approve and adopt the merger agreement and approve the merger or the election of directors, but that the ratification of the appointment of independent auditors is a “routine matter” on which brokers will be permitted to vote any un-voted shares. Accordingly, a broker non-vote will have the same effect as a vote

against approval and adoption of the merger agreement and approval of the merger and a “WITHHOLD” vote for the election of directors, but will have no effect on whether the other proposals are approved. Because Thomas Weisel Partners LLC is affiliated with Thomas Weisel Partners, NYSE policy specifies that when Thomas Weisel Partners LLC votes on “routine matters”, it may do so only in the same proportion as all other shares of record are voted with respect to each proposal.

Q:	*Can I change my vote after I have voted?*

Yes. Thomas Weisel Partners stockholders of record may revoke their proxies at any time prior to the time their proxies are voted at the Annual Meeting. Proxies may be revoked by written notice to the corporate secretary of Thomas Weisel Partners, by a later-dated proxy signed and returned by mail, or by attending the Annual Meeting and voting in person. However, attending the Annual Meeting without voting will not revoke your previously submitted proxy. Thomas Weisel Partners stockholders of record may also revoke proxies by a later-dated proxy using the telephone or the Internet voting procedures described on their proxy cards.

Thomas Weisel Partners stockholders whose shares are held in the name of a broker or nominee may change their votes by submitting new voting instructions to their brokers or nominees. Those Thomas Weisel Partners stockholders may not vote their shares in person at the Annual Meeting unless they obtain a signed proxy from the stockholder of record giving them the right to vote their shares.

Holders of exchangeable shares should refer to the Notice to Exchangeable Shareholders that accompanies this proxy statement/prospectus, informing such holders of their rights with respect to directing the voting of the votes attached to the share of Thomas Weisel Partners special voting preferred stock.

Q:	*Who will count the votes?*

Thomas Weisel Partners has retained BNY Mellon Stockholder Services to receive and tabulate the votes in connection with the Annual Meeting. Thomas Weisel Partners has also retained through BNY Mellon Stockholder Services an election inspector that will certify the results and perform any other acts required by the Delaware General Corporation Law.

Q:	*What do I do if I have questions?*

PTAS, Inc.

501 North Broadway

St. Louis, Missouri 63102

(314) 342-2000

PTAS, Inc., sometimes referred to in this proxy statement/prospectus as Merger Sub, is a newly-formed and wholly-owned subsidiary of Stifel. If Stifel and Thomas Weisel Partners complete the merger, Merger Sub will be merged with and into Thomas Weisel Partners, with Thomas Weisel Partners becoming a wholly-owned subsidiary of Stifel. Merger Sub was organized solely for use in the merger. Merger Sub has not carried on any activities to date, except for activities incidental to its formation and activities undertaken in connection with the transactions contemplated by the merger agreement.

The Merger

(see page 88)

Stifel and Thomas Weisel Partners agreed to the acquisition of Thomas Weisel Partners by Stifel under the terms of the merger agreement that is described in this proxy statement/prospectus. Pursuant to the merger agreement, Merger Sub will merge with and into Thomas Weisel Partners, with Thomas Weisel Partners continuing as a wholly owned subsidiary of Stifel. It is intended that the merger will be effected immediately after the effective time of the merger without further approval, authorization or direction from or by any of the parties to the merger agreement. Stifel and Thomas Weisel Partners have attached the merger agreement as Annex A to this proxy statement/prospectus. Stifel and Thomas Weisel Partners encourage you to read carefully the merger agreement in its entirety because it is the legal document that governs the merger.

Effects of the Merger; Merger Consideration

(see page 89)

At the effective time of the merger, each share of Thomas Weisel Partners common stock issued and outstanding, except for shares of Thomas Weisel Partners common stock that are owned by Thomas Weisel Partners or Stifel or by any direct or indirect wholly-owned subsidiary of Thomas Weisel Partners (which will be canceled as a result of the merger) will be converted into the right to receive, subject to certain adjustments as described below, 0.1364 shares of Stifel common stock.

Other than a possible adjustment under limited circumstances as described in the following paragraph, the exchange ratio of 0.1364 of a share of Stifel common stock is fixed, and it will not change between now and the date of the merger, including as a result of a change in the trading price of Stifel common stock or Thomas Weisel Partners common stock or the operating and financial performance of either company. Therefore, the specific dollar value of the shares of Stifel common stock received by Thomas Weisel Partners stockholders in the merger will depend on the market value of Stifel common stock at the time the merger is completed.

The exchange ratio will be adjusted if between signing of the merger agreement and the effective time of the merger the outstanding Stifel common stock or Thomas Weisel Partners common stock, or securities convertible or exchangeable into or exercisable into Stifel common stock or Thomas Weisel Partners common stock, is changed into a different number of shares or different class by reason of any distribution, reclassification, stock split (including a reverse split), stock dividend or distribution, recapitalization, merger, subdivision, issuer tender or exchange offer with a record date within such period, or any similar event occurs, in which case the exchange ratio will be adjusted to eliminate the effects of such event on the merger consideration.

Assuming that the holders of the exchangeable shares approve the Exchangeable Share Amendment, the exchangeable shares will not be converted into other securities as part of the merger. In that case, each exchangeable share will remain outstanding and become exchangeable for 0.1364 shares of Stifel common stock. In the event the Exchangeable Share Amendment is approved, at the effective time of the merger, the one outstanding share of Thomas Weisel Partners special voting preferred stock will be canceled and automatically converted into one share of Stifel special voting preferred stock. The one share of Stifel special voting preferred stock will entitle the holder to that number of votes equal to the number of shares of Stifel common stock issuable upon exchange of the exchangeable shares outstanding from time to time other than exchangeable shares held by Stifel or any person directly or indirectly controlled by or under common control of Stifel. Pursuant to the merger agreement, if the Exchangeable Share Amendment is not approved, Thomas Weisel Partners will take all actions necessary to (a) cause TWP Acquisition Company (Canada), Inc. to exercise its right to redeem all of the outstanding exchangeable shares or (b) acquire or cause TWP Holdings Company (Canada), ULC to acquire all of the outstanding exchangeable shares, and, as a result of the merger, holders of exchangeable shares would receive shares of Stifel common stock. For a more complete description of what holders of exchangeable shares will receive in the merger, see Annex C, entitled “Supplemental Information for the Holders of Exchangeable Shares.”

Stifel will not issue fractional shares of Stifel common stock in the merger. As a result, Thomas Weisel Partners shareholders will receive cash for any fractional shares of Stifel common stock that they would otherwise be entitled to receive in the merger. For a full description of the treatment of fractional shares, see “The Merger Agreement—Merger Consideration” beginning on page 87 of this proxy statement/prospectus.

For a full description of the merger consideration, see “The Merger Agreement—Merger Consideration” beginning on page 89 of this proxy statement/prospectus.

The close of business on April 30, 2010 was the record date for the Annual Meeting. Only Thomas Weisel Partners stockholders on the record date are entitled to notice of and to vote at the Annual Meeting. Each share of Thomas Weisel Partners common stock will be entitled to one vote on each matter to be acted upon at the Annual Meeting. The share of Thomas Weisel Partners special voting preferred stock held by the trustee is entitled to cast a number of votes equal to the number of the outstanding exchangeable shares, excluding shares held by Thomas Weisel Partners or any person directly or indirectly controlled by or under common control with Thomas Weisel Partners, on each matter to be acted upon at the Annual Meeting. On the record date, there were 26,748,099 shares of Thomas Weisel Partners common stock outstanding and one share of Thomas Weisel Partners special voting preferred stock held by the trustee (representing 6,183,121 exchangeable shares entitled to give voting instructions and therefore entitled to 6,183,121 votes). The holders of Thomas Weisel Partners common stock and Thomas Weisel Partners special voting preferred stock will vote together as a single class at the Annual Meeting.

The approval of holders of a majority of the voting power of the outstanding shares of Thomas Weisel Partners common stock and Thomas Weisel Partners special voting preferred stock (representing 6,183,121 exchangeable shares entitled to give voting instructions and therefore entitled to 6,183,121 votes), voting together as a single class, is required to approve and adopt the merger agreement and approve the merger.

Opinion of Thomas Weisel Partners’ Financial Advisor

(See page 73)

On April 25, 2010, Houlihan Lokey Howard & Zukin Financial Advisors, Inc., which we refer to as Houlihan Lokey, rendered its oral opinion to the board of directors of Thomas Weisel Partners (which was

subsequently confirmed in writing by delivery of Houlihan Lokey’s written opinion dated the same date) to the effect that, as of April 25, 2010, the exchange ratio provided for in the proposed merger was fair to the holders of Shares from a financial point of view.

Houlihan Lokey’s opinion was directed to the board of directors of Thomas Weisel Partners and addressed only the fairness to the holders of Shares, from a financial point of view, of the exchange ratio provided for in the proposed merger, and did not address any other aspect or implication of the proposed merger. The summary of Houlihan Lokey’s opinion in this proxy statement prospectus is qualified in its entirety by reference to the full text of its written opinion, which is included as Annex B to this proxy statement prospectus and which sets forth the procedures followed, assumptions made, qualifications and limitations on the review undertaken and other matters considered by Houlihan Lokey in preparing its opinion. However, neither Houlihan Lokey’s written opinion nor the summary of its opinion and the related analyses set forth in this proxy statement prospectus are intended to be, and do not constitute advice or a recommendation to any holder of Shares as to how such holder should act or vote with respect to any matter relating to the proposed merger. See “The Merger—Opinion of Thomas Weisel Partners’ Financial Advisor” beginning on page 73.

No Stifel Stockholder Approval

(See page 83)

Stifel stockholders are not required to approve and adopt the merger agreement or approve the merger or the issuance of shares of Stifel common stock or the share of Stifel special voting preferred stock as part of the merger consideration.

Interests of Certain Persons in the Merger

(See page 81)

When considering the recommendation by the Thomas Weisel Partners board of directors to vote FOR the proposal to approve and adopt the merger agreement and approve the merger, you should be aware that some directors and executive officers of Thomas Weisel Partners have interests in the merger that may be different from your interests. Stifel currently anticipates that the senior management of Thomas Weisel Partners, including several of its executive officers, will be executive officers and/or key employees of Stifel following the merger. Some directors, officers and employees of Thomas Weisel Partners who hold stock options and/or restricted stock units pursuant to existing plans may receive certain benefits following the closing of the merger, including accelerated vesting of those stock options and/or restricted stock units. Some directors, executive officers and employees of Thomas Weisel Partners who are parties to stockholders agreements with Thomas Weisel Partners are also entitled to early release of certain transfer restrictions with respect to the Thomas Weisel Partners common stock and the exchangeable shares held by them upon completion of the merger. Thomas Weisel Partners directors and officers will also receive indemnification from Stifel, and Stifel has agreed to provide and pay for liability insurance benefits for members of the Thomas Weisel Partners board of directors. The Thomas Weisel Partners board of directors was aware of these interests and considered them in approving the merger agreement and the merger.

Security Ownership by Directors and Executive Officers of Thomas Weisel Partners

(See page 148)

As of the record date for the Annual Meeting, the directors and executive officers of Thomas Weisel Partners and their affiliates, as a group, beneficially owned approximately 16.6% of the outstanding voting power of Thomas Weisel Partners common stock and Thomas Weisel Partners special voting preferred stock. The approval of the holders of a majority of the voting power of the outstanding shares of Thomas Weisel Partners common stock and Thomas Weisel Partners special voting preferred stock, voting together as a single class, is required to approve and adopt the merger agreement and approve the merger.

Ownership of Stifel Following the Merger

(See page 83)

If the merger is completed, holders of Thomas Weisel Partners common stock and exchangeable shares collectively will receive approximately 4.491 million shares of Stifel common stock in the merger or upon exchange of their exchangeable shares based on the number of shares of Thomas Weisel Partners common stock outstanding as of the record date.

Based on the number of shares of Stifel common stock and Thomas Weisel Partners common stock outstanding as of April 30, 2010, current Thomas Weisel Partners stockholders and exchangeable shareholders are expected to own approximately 12.6% of the outstanding common stock of Stifel (including Stifel common stock issuable in respect of any exchangeable shares) following the merger.

Material United States Federal Income Tax Consequences

(See page 146)

The merger is intended to constitute a reorganization for United States federal income tax purposes. If so treated, the exchange of your shares of Thomas Weisel Partners common stock for shares of Stifel common stock generally will not cause you to recognize gain or loss for U.S. federal income tax purposes. However, you will recognize income or gain with respect to cash received instead of any fractional shares of Stifel common stock. It is a condition to the merger that Stifel and Thomas Weisel Partners receive legal opinions as to the United States federal income tax treatment of the merger with respect to our companies and our stockholders. These opinions will not bind the Internal Revenue Service, which could take a different view.

Holders of exchangeable shares should refer to Annex C for a summary of material Canadian federal income tax considerations.

Accounting Treatment

(See page 85)

In accordance with accounting principles generally accepted in the United States, Stifel will account for the merger using the acquisition method of accounting for business combinations.

Stifel adopted Statement of Financial Accounting Standards No. 123R, Share Based Payment, as codified in ASC Topic 718, at the beginning of fiscal 2006. The stock-based compensation charges recorded in “Compensation and benefits” as a result of the adoption were not presented for the year ended December 31, 2005.

The compensation committee of Stifel’s Board of Directors is considering aligning its 2001 Equity Incentive Stock Plan with the provisions of Thomas Weisel Partners’ Equity Plan, as discussed under Thomas Weisel Partners Group, Inc. Selected Historical Financial Information table below, whereby any continued employment service requirements for vesting, if and so long as (but only for so long as) the holder of such restricted stock unit refrains from engaging in a competitive activity or a soliciting activity prior to the relevant vesting date or dates of such awards. Stifel believes that this action would result in the acceleration of the non-cash compensation expense associated with these equity awards resulting in an after tax charge of approximately $85-96 million with a corresponding increase to additional paid in capital.

On April 22, 2010, the board of directors of Thomas Weisel Partners approved the waiver of certain requirements for vesting of restricted stock units held by its current employees, including its executive officers (other than those employees who had given notice of an intention to terminate their employment prior to April 23, 2010). The waiver was effective as of April 23, 2010 and eliminated any continued employment service requirements for vesting under Section 11(d)(i) of Thomas Weisel Partners’ Third Amended and Restated Equity Incentive Plan, if and so long as (but only for so long as) the holder of such restricted stock unit refrains from engaging in a competitive activity or a soliciting activity prior to the relevant vesting date or dates of such awards. As a result of the waiver of any continued employment service requirements for vesting, Thomas Weisel Partners immediately recognized the remaining non-cash share based compensation expense for these grants of restricted stock unit awards that were subject only to the passage of time. Thomas Weisel Partners estimated the non-cash compensation share based compensation charge to be approximately $55 to $60 million.

(2)

The pro forma, as adjusted amounts depict results Thomas Weisel Partners estimates it would have had during the year ended December 31, 2006 if its reorganization transactions had taken place on January 1, 2006, as these amounts change tax expense to amounts that Thomas Weisel Partners estimates it would have paid if it were a corporation beginning January 1, 2006. Additionally, these amounts decrease net revenues by the amount of interest expense on notes payable issued to preferred shareholders upon consummation of the reorganization transactions. The amounts for the year ended December 31, 2006 reflect pro forma results of operations as if these transactions had occurred on January 1, 2006.

(3)	Reflects decrease in net revenues and net income before tax of $0.1 million for the estimated interest expense for the notes issued to Class D and D-1 preferred shareholders.

(4)

On a pro forma basis, the tax benefit for the year ended December 31, 2006 was decreased by the estimated additional tax expense of $1.5 million as if Thomas Weisel Partners were a corporation beginning January 1, 2006. The additional tax expense is attributable to Thomas Weisel Partners’ applicable tax rate, a combination of Federal, state and local income tax rates, of 42% applied to Thomas Weisel Partners’ pro forma net income for the period beginning January 1, 2006 through February 6, 2006.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited pro forma condensed combined financial statements are based on the historical financial statements of Stifel and Thomas Weisel Partners, combined and adjusted to give effect to the merger. The unaudited pro forma condensed combined statement of financial condition assumes that the merger took place on March 31, 2010 and combines Stifel’s March 31, 2010 unaudited consolidated statement of financial condition with Thomas Weisel Partners’ March 31, 2010 unaudited consolidated statement of financial condition.

The unaudited pro forma condensed combined statements of operations for the fiscal year ended December 31, 2009 and the three months ended March 31, 2010 assume that the merger took place on January 1, 2009. Stifel’s audited consolidated statement of operations for the fiscal year ended December 31, 2009 has been combined with Thomas Weisel Partners’ audited consolidated statement of operations for the fiscal year ended December 31, 2009 and Stifel’s unaudited consolidated statement of operations for the three months ended March 31, 2010 has been combined with Thomas Weisel Partners’ unaudited consolidated statement of operations for the three months ended March 31, 2010.

The historical consolidated financial information has been adjusted in the unaudited pro forma condensed combined financial statements to give effect to pro forma events that are (1) directly attributable to the merger, (2) factually supportable, and (3) with respect to the statements of operations, expected to have a continuing impact on the combined results. The unaudited pro forma condensed combined financial information should be read in conjunction with the accompanying notes to the unaudited pro forma condensed combined financial statements. In addition, the unaudited pro forma condensed combined financial information was based on and should be read in conjunction with the following historical consolidated financial statements and accompanying notes of Stifel and Thomas Weisel Partners for the applicable periods, which are incorporated by reference in this proxy statement/prospectus:

•

Separate historical financial statements of Stifel as of and for the year ended December 31, 2009 and the related notes included in Stifel’s Annual Report on Form 10-K for the year ended December 31, 2009;

•

Separate historical financial statements of Thomas Weisel Partners as of and for the year ended December 31, 2009 and the related notes included in Thomas Weisel Partners’ Annual Report on Form 10-K for the year ended December 31, 2009;

•

Separate unaudited historical financial statements of Stifel as of and for the three months ended March 31, 2010 and the related notes included in Stifel’s Quarterly Report on Form 10-Q for the period ended March 31, 2010; and

•

Separate unaudited historical financial statements of Thomas Weisel Partners as of and for the three months ended March 31, 2010 and the related notes included in Thomas Weisel Partners’ Quarterly Report on Form 10-Q for the period ended March 31, 2010.

The unaudited pro forma condensed combined financial information is presented for informational purposes only. The unaudited pro forma information is not necessarily indicative of what the combined financial position or results of operations actually would have been had the merger been completed as of the dates indicated. In addition, the unaudited pro forma condensed combined financial information does not purport to project the combined financial position or operating results for any future period.

The pro forma condensed combined financial statements do not reflect any cost savings that Stifel expects to achieve from operating efficiencies or synergies, or any expenditure related to restructuring actions to achieve cost savings. The effects of both cost savings and expenditures for restructuring could materially impact these pro forma condensed combined financial statements.

The unaudited pro forma condensed combined financial information has been prepared using the acquisition method of accounting for business combinations under accounting principles generally accepted in the United

States, or GAAP standards. Stifel is the acquirer for accounting purposes. The acquisition method of accounting requires management to obtain independent valuations that have yet to commence or progress to a point where there is sufficient information for a definitive measurement. Accordingly, the pro forma adjustments are preliminary and have been made by Stifel management solely for the purpose of providing unaudited pro forma condensed combined financial information. Differences between the preliminary estimates made during the preparation of the unaudited pro forma condensed combined financial statements and the final acquisition accounting could be material.

STIFEL FINANCIAL CORP.

NOTES TO THE PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS (UNAUDITED)

(in thousands, except per share amounts)

NOTE 1—Description of the Transaction

On April 26, 2010, Stifel Financial Corp. (“Stifel”) and Thomas Weisel Partners Group, Inc. (“Thomas Weisel Partners”) entered into a definitive agreement for Stifel to acquire for stock, 100% of the outstanding shares of Thomas Weisel Partners common stock.

If the merger is completed, each share of Thomas Weisel Partners common stock issued and outstanding prior to completion of the merger (other than shares owned by Stifel, shares owned by Thomas Weisel Partners or any of its direct or indirect wholly-owned subsidiaries) will be converted into the right to receive 0.1364 shares of Stifel common stock. Fractional shares of Stifel common stock will not be issued in the merger. Instead, cash will be paid in lieu of any fractional shares of Stifel common stock.

NOTE 2—Basis of Presentation

The unaudited pro forma condensed combined financial information is based on the historical financial statements of Stifel and Thomas Weisel Partners and are prepared and presented pursuant to the regulations of the Securities and Exchange Commission regarding pro forma financial information. The pro forma adjustments include the application of the acquisition method under FASB Accounting Standards Codification (“ASC”) Topic 805, “Business Combinations” with respect to the merger. ASC Topic 805 requires, among other things, that identifiable assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date, which is presumed to be the closing date of the merger.

The merger is expected to close on or around June 30, 2010. Accordingly, the pro forma adjustments reflected in the accompanying condensed combined pro forma financial statements may be materially different from the actual acquisition accounting adjustments required as of the acquisition date. In addition, ASC Topic 805 establishes that the value of equity related consideration transferred in a business combination be measured as of the acquisition date. Depending on the magnitude of changes in the value of Stifel common stock between this filing date and the acquisition date, the aggregate value of the merger consideration paid to the stockholders of Thomas Weisel Partners could differ from the amount assumed in these unaudited pro forma condensed combined financial statements.

Under ASC Topic 820, “Fair Value Measurements and Disclosures,” “fair value” is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 specifies a hierarchy of valuation techniques based on the nature of the inputs used to develop the fair value measures. This is an exit price concept for the valuation of the asset or liability. In addition, market participants are assumed to be unrelated buyers and sellers in the principal or the most advantageous market for the asset or liability. Fair value measurements for an asset assume the highest and best use by these market participants. Many of these fair value measurements can be highly subjective and it is also possible that other professionals, applying reasonable judgment to the same facts and circumstances, could develop and support a range of alternative estimated amounts.

Under ASC Topic 805, merger-related transaction costs (such as advisory, legal, valuation and other professional fees) are not included as components of consideration transferred but are accounted for as expenses in the periods in which the costs are incurred. We have estimated that total transaction related costs will be approximately $2.2 million ($1.3 million, net of tax). These costs are reflected in “accounts payable and accrued expenses” in the accompanying unaudited pro forma condensed combined statement of financial condition. Because we are required to expense these costs as they are incurred, we have charged them to retained earnings

(in thousands, except per share amounts)

as of March 31, 2010. No adjustment has been made to the unaudited pro forma condensed combined statement of operations for these costs as they do not have a continuing impact on the results of the combined company.

The pro forma condensed combined financial statements do not reflect any cost savings that Stifel expects to achieve from operating efficiencies or synergies, or any expenditure related to restructuring actions to achieve such cost savings. The effects of both cost savings and expenditures for restructuring could materially impact these pro forma condensed combined financial statements.

Certain Thomas Weisel Partners’ amounts have been reclassified to conform to Stifel’s presentation. These reclassifications had no effect on previously reported net earnings. There were no material transactions between Stifel and Thomas Weisel Partners during the periods presented in the unaudited pro forma condensed combined financial statements that would need to be eliminated.

NOTE 3—Accounting Policies

Upon completion of the merger, Stifel will perform a detailed review of Thomas Weisel Partners’ accounting policies. As a result of that review, Stifel may identify differences between the accounting policies of the two companies that, when conformed, could have a material impact on the combined financial statements. At this time, Stifel is not aware of any differences that would have a material impact on the combined financial statements and the unaudited pro forma condensed combined financial statements do not assume any significant differences in accounting policies.

NOTE 4—Estimate of Consideration Expected to be Transferred and Purchase Price to be Allocated

A preliminary estimate of consideration expected to be transferred to effect the merger and the aggregate purchase price to be allocated is presented in the table below. These estimates are based upon 32,931 outstanding shares of Thomas Weisel Partners common stock as of April 30, 2010 (in thousands, except exchange ratio and share price):


Thomas Weisel Partners shares outstanding as of April 30, 2010		32,931
Estimated Thomas Weisel Partners shares issuable pursuant to conversion of stock options, restricted stock units and warrants as of April 30, 2010		9,349

Total Thomas Weisel Partners shares and share equivalents prior to close		42,280
Exchange ratio		0.1364

Total Stifel shares to be issued		5,767
Stifel closing share price on April 30, 2010		57.33

Purchase price to be allocated	$	330,623

The estimated value of Stifel shares issuable as merger consideration is based upon the closing Stifel common stock price as of April 30, 2010 of $57.33 per share. Accordingly, the unaudited pro forma condensed combined financial statements assume that Stifel will issue 5,767 shares with a value of approximately $330.6 million in connection with the merger. In addition, Thomas Weisel Partners’ shares outstanding as of April 30, 2010 include approximately 6,183 exchangeable shares of TWP Acquisition Company (Canada), Inc. which will remain outstanding following the merger and will become exchangeable for approximately 843 shares of Stifel

(in thousands, except per share amounts)

common stock. In certain circumstances, the consideration to be transferred upon completion of the merger may differ from the amounts assumed in these unaudited pro forma condensed combined financial statements. The aggregate value of the consideration paid could be significantly impacted, among other factors, if the per share price of Stifel common stock deviates from $57.33 per share, the price utilized in the above table.

Stifel has agreed to provide for Stifel common stock equity awards to replace existing Thomas Weisel Partners’ equity awards, subject to the same terms and conditions, including any vesting requirements, as were applicable prior to the merger. Stifel common stock potentially issuable in respect to replacement equity awards is approximately 1,209 shares.

NOTE 5—Estimate of Assets to be Acquired and Liabilities to be Assumed

The following is a discussion of the adjustments made to Thomas Weisel Partners’ assets and liabilities in connection with the preparation of these unaudited pro forma condensed combined financial statements. Each of these adjustments represent preliminary estimates of the fair values of Thomas Weisel Partners’ assets and liabilities. Based on Stifel’s acquisition history and a review of Thomas Weisel Partners’ consolidated statement of financial condition as of March 31, 2010, Stifel believes a significant portion of the purchase price will be allocated to intangible assets, deferred tax assets and goodwill. Given the nature of the industries in which Stifel and Thomas Weisel Partners operate, the majority of assets and liabilities are recorded at fair value, Stifel has limited its adjustments to these areas. For purposes of preparing the unaudited pro forma condensed combined financial statements, the carrying value of assets and liabilities in Thomas Weisel Partners’ financial statements, other than the ones described below, are considered to approximate fair value of those assets and liabilities.

The following is a preliminary estimate of the assets to be acquired and liabilities to be assumed by Stifel in the merger, reconciled to the estimate of consideration expected to be transferred upon the completion of the merger (in thousands):


Book value of Thomas Weisel Partners net assets acquired March 31, 2010	$	127,784
Adjustments to:
Goodwill		112,995
Intangible assets, net		32,208
Deferred tax assets		57,636

Total adjustments		202,839

Purchase price to be allocated (See Note 4)	$	330,623

Goodwill: Goodwill is calculated as the excess of the merger date fair value of the consideration expected to be transferred over the fair value assigned to the identifiable assets acquired, including identifiable intangible assets, and liabilities assumed. Goodwill is not amortized but rather is subject to an annual impairment test.

Intangible assets: Reflects a preliminary estimate of the fair value of potential identifiable intangible assets as a result of the merger. As previously noted, the final allocation of the purchase price to identifiable intangible assets may differ significantly from amounts in these unaudited pro forma condensed combined financial statements.

STIFEL FINANCIAL CORP.

NOTES TO THE PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS (UNAUDITED)—(Continued)

(in thousands, except per share amounts)

Deferred tax assets: Deferred income taxes at March 31, 2010 have been adjusted for temporary differences caused by book and tax differences after the allocation of the pro forma purchase price using Stifel’s statutory rate of 40 percent.

The fair value of Thomas Weisel Partners’ assets and liabilities and the appropriate useful lives will be determined after the completion of the merger based on a valuation performed by Stifel management with the assistance of an independent third-party valuation firm. Actual adjustments will be made when the merger is completed and will be based on Thomas Weisel Partners’ assets and liabilities at that time. Accordingly, the actual adjustments to Thomas Weisel Partners’ assets and liabilities may differ materially from the estimates reflected in these unaudited pro forma condensed combined financial statements. Any changes to the initial estimates of the fair value of the assets acquired and liabilities assumed, after recording any identifiable intangible assets at fair value, will be allocated to residual goodwill.

Provision for income taxes

C. Reflects the income tax effect of pro forma adjustments based on Stifel’s statutory rate. For purposes of this unaudited pro forma combined financial information, the statutory rate of 40 percent has been used for all periods presented. This rate does not reflect Stifel’s effective tax rate, which includes other tax items, such as foreign taxes, as well as other tax charges or benefits, and does not take into account any historical or possible future tax events that may impact the combined company.

Earnings per common share

D. Pro forma earnings per common share for the year ended December 31, 2009 and the three months ended March 31, 2010, have been calculated based on the estimated weighted average number of common shares outstanding on a pro forma basis, as described below. The pro forma weighted average number of common shares outstanding for the year ended December 31, 2009 and the three months ended March 31, 2010, have been calculated as if the acquisition shares had been issued and outstanding on January 1, 2009. No dilutive effect is assumed for the exchange of Thomas Weisel Partners’ stock options and restricted stock units as the exchange is assumed to occur at the then current market price of Stifel common stock.

The following table sets forth the computation of pro forma earnings per share for the year ended December 31, 2009 and the three months ended March 31, 2010 (in thousands):


	Year ended December 31, 2009		Three months ended March 31, 2010
Historical Stifel average outstanding shares		28,297	30,720
Pro forma Stifel equivalent shares to be issued (see Note 4)		5,756	5,767

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

This proxy statement/prospectus (including the documents incorporated by reference into this proxy statement/prospectus) contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that involve risks, uncertainties and assumptions, that, if they never materialize or if they prove incorrect, could cause the actual results of Stifel and its consolidated subsidiaries, Thomas Weisel Partners and its consolidated subsidiaries, or the combined company, to differ materially from those expressed or implied by such forward-looking statements. All statements other than statements of historical fact are statements that could be deemed forward-looking statements, including, but not limited to, statements about: future financial and operating results; Stifel’s, Thomas Weisel Partners’ and the combined company’s plans, objectives, strategies, expectations and intentions; products and operations; Stifel’s and Thomas Weisel Partners’ expectations with respect to the synergies, costs and charges, capitalization and anticipated financial impacts of the merger and related transactions; benefits of the transaction to customers, stockholders and employees; the expected tax treatment of the transaction; approval and adoption of the merger agreement and approval of the merger by Thomas Weisel Partners stockholders; the satisfaction of the closing conditions to the merger; the timing of the completion of the merger; future economic conditions or performance; statements of belief; and any statements of assumptions underlying any of the foregoing.

When used in this proxy statement/prospectus (including the documents incorporated by reference into this proxy statement/prospectus), words such as “may”, “might”, “should”, “expects”, “anticipates”, “believes”, “estimates”, “intends”, “plans”, “seeks”, “will”, “should”, “would”, “projects”, “predicts”, “continues” and similar expressions or the negatives of these terms and other comparable terminology help to identify these forward-looking statements.

Most of the risks, uncertainties and assumptions referred to above are outside Stifel’s and Thomas Weisel Partners’ control and are difficult to predict. Factors that may cause such differences include, but are not limited to:

•

those discussed and identified in public filings with the Securities and Exchange Commission, or the SEC, made by Stifel or Thomas Weisel Partners;

•

the inability to close the merger in a timely manner;

•

the inability to complete the merger due to the failure to obtain stockholder approval and adoption of the merger agreement and approval of the merger or the failure to satisfy other conditions to completion of the merger, including required regulatory approvals;

•

the failure of the transaction to close for any other reason;

•

the possibility that the integration of Thomas Weisel Partners’ business and operations with those of Stifel may be more difficult and/or take longer than anticipated, may be more costly than anticipated and may have unanticipated adverse results relating to Thomas Weisel Partners’ or Stifel’s existing businesses;

•

the challenges of integrating and retaining key employees;

•

the effect of the announcement of the transaction on Stifel’s, Thomas Weisel Partners’ or the combined company’s respective business relationships, operating results and business generally;

•

the possibility that the anticipated synergies and cost savings of the merger will not be realized, or will not be realized within the expected time period;

•

the possibility that the merger may be more expensive to complete than anticipated, including as a result of unexpected factors or events;

•

the challenges of maintaining and increasing revenues on a combined company basis following the close of the merger;

•

diversion of management’s attention from ongoing business concerns;

•

general competitive, economic, political and market conditions and fluctuations;

•

actions taken or conditions imposed by the United States and foreign governments;

•

adverse outcomes of pending or threatened litigation or government investigations; and

•

the impact of competition in the industries and in the specific markets in which Stifel and Thomas Weisel Partners, respectively, operate.

The foregoing list is not exclusive. Additional information concerning these and other risks is discussed under the caption entitled “Risk Factors” beginning on page 43. All forward-looking statements included in this proxy statement/prospectus (including the documents incorporated by reference into this proxy statement/prospectus) and all subsequent written and oral forward-looking statements concerning Stifel, Thomas Weisel Partners, the Annual Meeting, the merger, the related transactions or other matters attributable to Stifel or Thomas Weisel Partners, or any person acting on their behalf, are expressly qualified in their entirety by the cautionary statements above. These forward-looking statements speak only as of the date on which the statements were made and Stifel and Thomas Weisel Partners expressly disclaim any obligation to release publicly any updates or revisions to any forward-looking statement included in this proxy statement/prospectus or elsewhere, whether written or oral, relating to the matters discussed in this proxy statement/prospectus.

RISK FACTORS

By voting in favor of the proposal to approve and adopt the merger agreement and approve the merger, you will be choosing to invest in Stifel common stock. Although, if the Exchangeable Share Amendment is approved by the holders of the exchangeable shares, all exchangeable shares will remain outstanding following the merger, each exchangeable share will become exchangeable for shares of Stifel common stock, as described in Annex C. Accordingly, the following risk factors and other information contained in this proxy statement/prospectus and the documents incorporated by reference into this proxy statement/prospectus are applicable to holders of exchangeable shares. An investment in Stifel common stock may involve significant risk. You should carefully consider the following risk factors, as well as the other information contained in this proxy statement/prospectus and the documents incorporated by reference into this proxy statement/prospectus, in evaluating whether to vote your shares to approve and adopt the merger agreement and approve the merger. This summary of risks is not exhaustive. New risks may emerge from time to time and it is not possible to predict all risk factors, nor can we assess the impact of all factors on the merger and the combined company following the merger or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in or implied by any forward-looking statements. For further discussion of risk factors relating to the business of Stifel, please see the Risk Factors in Stifel’s current filings with the SEC. See “Where You Can Find More Information” beginning on page 153.

Risks Related to the Merger

As a holder of Thomas Weisel Partners common stock, if the merger is completed, you will receive 0.1364 shares of Stifel common stock for each share of Thomas Weisel Partners common stock you own and, if the Exchangeable Share Amendment is approved, as a holder of exchangeable shares, each exchangeable share you own will become exchangeable for 0.1364 shares of Stifel common stock, in each case notwithstanding any changes in the value of Thomas Weisel Partners common stock or Stifel common stock.

Upon completion of the merger, each share of Thomas Weisel Partners common stock will be exchanged for 0.1364 shares of Stifel common stock and, if the Exchangeable Share Amendment is approved, each exchangeable share will be exchangeable for 0.1364 shares of Stifel common stock. There will be no adjustment for changes to reflect the market price of either Thomas Weisel Partners common stock or Stifel common stock or the operating and financial performance of either company. Accordingly, the specific dollar value of the Stifel common stock that you will receive (or that will be reserved for issuance in respect of the exchangeable shares) upon completion of the merger will depend on the market value of Stifel common stock at the time of completion of the merger. The merger may not be completed immediately following the Annual Meeting if all regulatory approvals have not yet been obtained and other conditions have not been satisfied or waived. Neither company is permitted to terminate the merger agreement or re-solicit the vote of Thomas Weisel Partners stockholders solely because of changes in the market prices of either company’s common stock or because of changes in the operating and financial performance of either company that do not amount to a material adverse effect, as defined in the merger agreement. Stock price changes may result from a variety of factors, including, among others, general market and economic conditions, changes in Stifel’s and Thomas Weisel Partners’ respective current and anticipated businesses and operations as well as regulatory considerations. Many of these factors are beyond Stifel’s and Thomas Weisel Partners’ control. Additionally, future sales of substantial amounts of Stifel common stock in the public market, or the availability of such shares for sale, including shares issued upon the exercise of outstanding options, could adversely affect the market price of Thomas Weisel Partners common stock and Stifel common stock. You should obtain current market quotations for shares of Stifel common stock and for shares of Thomas Weisel Partners common stock. We cannot assure you that the value of the Stifel common stock that you will receive (or that will be reserved for issuance in respect of the exchangeable shares) in the merger will not decline prior to or after the merger.

Thomas Weisel Partners directors and executive officers have interests that may influence them to support and approve the merger.

Some of the directors and executive officers of Thomas Weisel Partners may receive certain benefits as a result of the merger, including enhancement in employment terms and continuing indemnification against liabilities. They may also have certain Thomas Weisel Partners stock options and other equity awards and existing employment terms that provide them with interests in the merger, such as accelerated vesting of restricted stock units and stock options in certain circumstances following the closing of the merger, or potential cash severance payments following the closing of the merger, that are different from, or are in addition to, the interests of other stockholders in the merger. As a result, these directors and officers may be more likely to vote to approve and adopt the merger agreement and approve the merger than if they did not have these interests. Some of these executive officers and directors have already agreed to vote in favor of the proposal to approve and adopt the merger agreement and approve the merger and may be released from certain transfer restrictions on their shares of Thomas Weisel Partners common stock or exchangeable shares upon the approval and adoption of the merger agreement and approval of the merger. As of the close of business on the record date for the Annual Meeting at which the merger agreement will be presented and voted upon, Thomas Weisel Partners officers and directors beneficially owned approximately 16.6% of the voting power of the outstanding shares of Thomas Weisel Partners common stock and Thomas Weisel Partners special voting preferred stock entitled to vote at the meeting. Subsequent to the effective time of the merger, Stifel intends to grant equity awards to certain Thomas Weisel Partners employees, particularly those in the sales and trading areas, as well as approximately 35,000 Stifel restricted stock unit awards to Thomas W. Weisel. In addition, subsequent to the effective time of the merger, Stifel intends to waive the continued employment service requirements for vesting under its equity incentive plans, so long as the award recipients agree to refrain from engaging in competitive activities or soliciting activities. For a description of some of these interests, see the sections entitled “Interests of Certain Persons in the Merger”, “The Merger Agreement” and “Other Agreements Related to the Merger” beginning on page 81, page 88 and page 103, respectively, of this proxy statement/prospectus.

The market price of the shares of Stifel common stock may be affected by factors different from those affecting the shares of Thomas Weisel Partners common stock.

Upon completion of the merger, holders of Thomas Weisel Partners common stock will become holders of Stifel common stock and, if the Exchangeable Share Amendment is approved, exchangeable shares will become exchangeable for shares of Stifel common stock. The businesses of Stifel differ from those of Thomas Weisel Partners in certain respects and, accordingly, the results of operations of the combined company and the market price of Stifel common stock following the merger may be affected by factors different from those currently affecting the independent results of operations of Stifel and Thomas Weisel Partners. For example, Stifel’s financial performance depends relatively more on its retail brokerage business within its Global Wealth Management Segment, which derives its revenues principally from commissions, principal transactions and, asset management and service fees and may be more closely tied to changes in stock prices, trading volumes and liquidity. In addition, as a bank holding company, Stifel is subject to regulation by the Federal Reserve, and its banking subsidiary, Stifel Bank, is subject to regulation by the FDIC, as described in “—Regulatory and legal developments could adversely affect Stifel’s business and financial condition” on page 53 below.

On the other hand, Thomas Weisel Partners’ financial performance depends relatively more on its investment banking business which (1) is principally focused on growth sectors in the economy, including technology, healthcare, energy and mining, (2) depends significantly on transactions by venture capital backed companies in those sectors and (3) depends on capital markets and strategic advisory engagements that are by nature non-recurring and may not result in revenues from subsequent engagements.

As a result of the merger, the financial performance of the combined firm, from the perspective of current Stifel shareholders, will be relatively more subject to the risks associated with Thomas Weisel Partners’ investment banking business and, from the perspective of current Thomas Weisel Partners shareholders, will be

relatively more subject to the risks associated with Stifel’s retail brokerage businesses. For a discussion of the businesses of Stifel and Thomas Weisel Partners and of certain factors to consider in connection with those businesses, see the documents incorporated by reference into this proxy statement/prospectus referred to under “Where You Can Find More Information” beginning on page 153.

The market price of Thomas Weisel Partners common stock prior to the merger may also not be reflective of Thomas Weisel Partners’ underlying current operating and financial performance or its longer term prospects because the market price for the Thomas Weisel Partners shares may begin to track the share price of Stifel common stock if investors assume that the merger is likely to be completed.

Stifel and Thomas Weisel Partners may experience difficulties, unexpected costs and delays in integrating their businesses, business models and cultures and the combined company may not realize synergies, efficiencies or cost savings from the merger.

Stifel and Thomas Weisel Partners have operated and, until the merger is completed, will continue to operate, independently. The success of the combined company following the completion of the merger may depend in large part on the ability to integrate the two companies’ businesses, business models and cultures. In particular, investment banking businesses such as Thomas Weisel Partners’ and Stifel’s depend to a large degree on the efforts and performance of individual employees whose efforts and performance may be affected by any difficulties in the integration of the businesses. In the process of integrating Stifel and Thomas Weisel Partners, Stifel may experience difficulties, unanticipated costs and delays. The challenges involved in the integration may include:

•

the necessity of coordinating geographically disparate organizations and addressing possible differences in corporate and regional cultures and management philosophies;

•

managing the combined company at geographically separate locations that employ a significant number of employees;

•

retaining personnel from different companies and integrating them into a new business culture while maintaining their focus on providing consistent, high-quality client service;

•

integrating information technology systems and resources;

•

integrating accounting systems and adjusting internal controls to cover Thomas Weisel Partners’ operations;

•

unforeseen expenses or delays associated with the transaction;

•

performance shortfalls at one or both of the companies as a result of the diversion of management’s attention to the transaction; and

•

meeting the expectations of clients with respect to the integration.

The integration of certain operations, in particular the two companies’ research and brokerage businesses, following the transaction will take time and will require the dedication of significant management resources, which may temporarily distract management’s attention from the ongoing businesses of the combined company. Employee uncertainty and lack of focus during the integration process may also disrupt the businesses of the combined company.

It is possible that the integration process could result in the loss of key employees, diversion of each company’s management’s attention, the disruption or interruption of, or the loss of momentum in, each company’s ongoing business or inconsistencies in standards, controls, procedures and policies, any of which could adversely affect the combined company’s ability to maintain relationships with clients and employees or the ability to achieve the anticipated benefits of the transaction, or could reduce the combined company’s earnings or otherwise adversely affect the business and financial results of the combined company. In addition,

the integration process may strain the combined company’s financial and managerial controls and reporting systems and procedures. This may result in the diversion of management and financial resources from the combined company’s core business objectives.

Even if Stifel and Thomas Weisel Partners are able to integrate such businesses and operations successfully, there can be no assurance that this integration will result in any synergies, efficiencies or cost savings or that any of these benefits will be achieved within a specific time frame. Any of these factors could adversely affect the combined company’s business and results of operations.

If Stifel is unable to integrate Thomas Weisel Partners personnel successfully or retain key Thomas Weisel Partners or Stifel personnel after the merger is completed, the combined company’s business may suffer.

Stifel’s ability to obtain and successfully execute its business depends upon the personal reputation, judgment, business generation capabilities and project execution skills of Stifel’s and Thomas Weisel Partners’ senior professionals. Any management disruption or difficulties in integrating Stifel’s and Thomas Weisel Partners’ professionals could result in a loss of clients and customers or revenues from clients and customers and could significantly affect the combined company’s business and results of operations.

The success of the merger will depend in part on Stifel’s ability to retain the talents and dedication of the professionals currently employed by Stifel and Thomas Weisel Partners. It is possible that these employees might decide not to remain with Stifel or Thomas Weisel Partners while Stifel and Thomas Weisel Partners work to complete the merger or with Stifel after the merger is completed. If key employees terminate their employment, or insufficient numbers of employees are retained to maintain effective operations, the combined company’s business activities might be adversely affected, management’s attention might be diverted from successfully integrating Thomas Weisel Partners’ operations to hiring suitable replacements, and the combined company’s business might suffer. In addition, Stifel and Thomas Weisel Partners might not be able to locate suitable replacements for any key employees that leave either company or offer employment to potential replacements on reasonable terms.

Integration of Thomas Weisel Partners’ operations with Stifel’s operations may impair Stifel’s ability to achieve the expected benefits of the merger.

Following completion of the transaction, Stifel expects to make changes to certain aspects of each of the companies’ operations to integrate Thomas Weisel Partners’ operations with those of Stifel. For example, Stifel may be required to change the way in which research professionals interact with investment banking professionals to conform to the Global Research Analyst Settlement. In addition, Stifel expects that the merger could affect each of the companies’ existing client relationships or its ability to enter into new client relationships. Any changes that Stifel makes to each of the companies’ operations, could disrupt their businesses and client relationships and could materially and adversely affect Stifel’s ability to achieve the expected benefits of the transaction and its business and results of operations.

The merger is subject to conditions to closing that could result in the merger being delayed or not consummated, which could negatively impact Stifel’s and Thomas Weisel Partners’ stock price and the combined company’s future business and operations. In order to obtain required regulatory approvals, Stifel may become subject to conditions that it does not currently anticipate.

The merger is subject to conditions to closing as set forth in the merger agreement, including obtaining the requisite Thomas Weisel Partners stockholder approval. If any of the conditions to the transaction are not satisfied or, where permissible, not waived, the merger will not be consummated. Failure to consummate the transaction could negatively impact Thomas Weisel Partners’ stock price, future business and operations, and financial condition. Any delay in the consummation of the merger or any uncertainty about the consummation of the merger may adversely affect the future businesses, growth, revenue and results of operations of Stifel, Thomas Weisel Partners or the combined company.

The transaction is subject to several U.S. and Canadian regulatory approvals, as well as other regulatory approvals. These regulatory approvals may not be received, or may be received later than anticipated. Regulatory approvals that are received may impose restrictions or conditions that restrict the combined company’s activities or otherwise adversely affect the combined company’s business and results of operations.

The delay in closing the planned merger could have an adverse effect on Thomas Weisel Partners’ revenues in the near-term.

To the extent a prolonged delay in completing the planned merger creates uncertainty among Thomas Weisel Partners’ clients, such delay could have an adverse effect on Thomas Weisel Partners’ results of operations, and quarterly revenues could be substantially below market expectations and could cause a reduction in the stock price of Thomas Weisel Partners common stock.

The pro forma financial statements are presented for illustrative purposes only and may not be an indication of the combined company’s financial condition or results of operations following the merger.

The pro forma financial statements contained in this proxy statement/prospectus are presented for illustrative purposes only and may not be an indication of the combined company’s financial condition or results of operations following the merger for several reasons. For example, the pro forma financial statements have been derived from the historical financial statements of Stifel and Thomas Weisel Partners and certain adjustments and assumptions have been made regarding the combined company after giving effect to the merger. The information upon which these adjustments and assumptions have been made is preliminary, and these kinds of adjustments and assumptions are difficult to make with complete accuracy. Moreover, the pro forma financial statements do not reflect all costs that are expected to be incurred by the combined company in connection with the transaction. For example, the impact of any incremental costs incurred in integrating the two companies is not reflected in the pro forma financial statements. As a result, the actual financial condition and results of operations of the combined company following the transaction may not be consistent with, or evident from, these pro forma financial statements.

In addition, the assumptions used in preparing the pro forma financial information may not prove to be accurate, and other factors may affect the combined company’s financial condition or results of operations following the transaction. Any potential decline in the combined company’s financial condition or results of operations may cause significant variations in the stock price of the combined company. See the section entitled “Unaudited Pro Forma Condensed Combined Financial Statements” beginning on page 29.

Stifel and Thomas Weisel Partners expect to incur significant costs associated with the merger.

Stifel estimates that it will incur direct transaction costs of approximately $2.2 million associated with the merger. In addition, Thomas Weisel Partners estimates that it will incur direct transaction costs of approximately $2.5 million which will be recognized as expenses as incurred. Stifel and Thomas Weisel Partners believe the combined entity may incur charges to operations, which are not currently reasonably estimable, in the quarter in which the merger is completed or the following quarters, to reflect costs associated with integrating the two companies. There can be no assurance that the combined company will not incur additional material charges in subsequent quarters to reflect additional costs associated with the merger and the integration of the two companies. Although Stifel expects that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, should allow Stifel to offset incremental transaction and merger-related costs over time, this net benefit may not be achieved in the near term, or at all.

The merger may not be accretive and may cause dilution to Stifel’s earnings per share, which may negatively affect the market price of Stifel common stock.

Stifel currently anticipates that the merger will be accretive to earnings per share during the first full calendar year after the merger. This expectation is based on preliminary estimates which may materially change.

Stifel could also encounter additional transaction and integration—related costs or other factors such as the failure to realize all of the benefits anticipated in the merger. All of these factors could cause dilution to Stifel’s earnings per share or decrease or delay the expected accretive effect of the merger and cause a decrease in the price of Stifel common stock.

The shares of Stifel common stock to be received by Thomas Weisel Partners stockholders or reserved for issuance for holders of exchangeable shares if the merger is approved and consummated will have different rights from the shares of Thomas Weisel Partners common stock.

Upon completion of the merger, Thomas Weisel Partners stockholders will become Stifel stockholders and their rights as stockholders will be governed by Stifel’s certificate of incorporation and bylaws. If the Exchangeable Share Amendment is approved, exchangeable shares will become exchangeable for shares of Stifel common stock. The rights associated with Thomas Weisel Partners common stock are different from the rights associated with Stifel common stock. Please see “Comparison of Rights of Stifel Stockholders and Thomas Weisel Partners Stockholders” beginning on page 104 for a discussion of the different rights associated with Stifel common stock.

The termination fee and restrictions on solicitation contained in the merger agreement may discourage other companies from trying to acquire Thomas Weisel Partners.

Until the completion of the merger, with limited exceptions, the merger agreement prohibits Thomas Weisel Partners from entering into an alternative acquisition transaction with, or soliciting any alternative acquisition proposal from, another party. Thomas Weisel Partners has agreed under certain circumstances to pay Stifel a termination fee equal to $10,000,000, including where the Thomas Weisel Partners board of directors withdraws its support of the merger to enter into a business combination with a third party. These provisions could discourage other companies from trying to acquire Thomas Weisel Partners even though those other companies might be willing to offer greater value to Thomas Weisel Partners stockholders than Stifel has offered in the merger.

Risks Related to Thomas Weisel Partners if the Merger Is Not Completed

If the merger is not completed, the price of Thomas Weisel Partners common stock and future business and operations could be harmed.

If the merger is not completed, Thomas Weisel Partners may be subject to the following material risks, among others:

•

Thomas Weisel Partners may not be able to find a party willing to pay an equivalent or more attractive exchange ratio than the ratio offered by Stifel;

•

the price of Thomas Weisel Partners common stock may decline to the extent that the current market price of Thomas Weisel Partners common stock reflects an assumption that the merger will be completed;

•

certain of Thomas Weisel Partners’ costs related to the merger, such as legal, accounting and certain financial advisory fees, must be paid even if the merger is not completed;

•

Thomas Weisel Partners would not realize the benefits it expects by being part of a combined company with Stifel, as well as the potentially enhanced financial position as a result of being part of the combined company;

•

the diversion of management attention from Thomas Weisel Partners’ day-to-day business and the unavoidable disruption to its employees and its relationships with clients as a result of efforts and uncertainties relating to Thomas Weisel Partners’ anticipated merger with Stifel may detract from Thomas Weisel Partners’ ability to grow revenues and minimize costs, which, in turn may lead to a loss of market position that Thomas Weisel Partners could be unable to regain if the merger does not occur;

•

under the merger agreement, Thomas Weisel Partners is subject to certain restrictions on the conduct of its business prior to completing the merger which may affect its ability to execute certain of its business strategies; and

•

Thomas Weisel Partners may not be able to continue its present level of operations, may need to scale back its business and may not be able to take advantage of future opportunities or effectively respond to competitive pressures, any of which could have a material adverse effect on its business and results of operations.

Stockholders may sell substantial amounts of Thomas Weisel Partners common stock in the public market, which is likely to depress the price of Thomas Weisel Partners common stock.

A significant number of shares of Thomas Weisel Partners common stock may be sold at any time prior to the merger. If Thomas Weisel Partners’ current stockholders sell Thomas Weisel Partners common stock in the public market prior to the merger, it is likely that arbitrageurs will acquire such shares. These arbitrageurs would likely sell all such shares in the public market immediately following any announcement, or anticipated announcement, that the merger with Stifel failed, or will likely fail, to close for regulatory or other reasons, which in turn would likely cause the market price of Thomas Weisel Partners common stock to decline.

In addition to the other negative effects on Thomas Weisel Partners, all such sales of Thomas Weisel Partners common stock might make it more difficult for Thomas Weisel Partners to sell equity or equity-related securities in the future if the merger with Stifel is not completed.

Risks Relating to Thomas Weisel Partners

Thomas Weisel Partners is, and will continue to be, subject to the risks described in Part I, Item 1A in Thomas Weisel Partners’ Annual Report on Form 10-K for the year ended December 31, 2009, filed with the SEC on March 12, 2010, and in Part II, Item 1A in Thomas Weisel Partners’ Quarterly Report on Form 10-Q for the quarter ended March 31, 2010 filed with the SEC on May 10, 2010, incorporated by reference into this proxy statement/prospectus. See “Where You Can Find More Information” beginning on page 153 for the location of information incorporated by reference into this proxy statement/prospectus.

Risks Relating to Stifel

In addition to the other information set forth in this report, you should carefully consider the following factors which could materially affect Stifel’s business, financial condition or future results of operations. Although the risks described below are those that management believes are the most significant, these are not the only risks facing Stifel. Additional risks and uncertainties not currently known to Stifel or that Stifel currently does not deem to be material also may materially affect Stifel’s business, financial condition or future results of operations. Stifel may amend or supplement these risk factors from time to time in other reports it files with the SEC.

Stifel’s results of operations may be adversely affected by conditions in the global financial markets and economic downturn.

Stifel’s results of operations are materially affected by conditions in the financial markets and economic conditions generally, both in the United States and elsewhere around the world. Significant weaknesses and volatility in the credit markets stemming from difficulties in the U.S housing market spread to the broader financial market and lead to a decline in global economic growth that has resulted in a significant recession. Specifically, dramatic declines in U.S. housing market values, together with increasing foreclosures and unemployment, have resulted in significant write-downs of asset values by financial institutions, including government-sponsored entities, as well as major commercial and investment banks. These write-downs, which were initially associated with mortgaged-backed securities but which have substantially spread to credit default swaps and other derivative securities, in turn have caused many financial institutions to seek additional capital, to merge with larger and stronger institutions and, in some cases, to fail. Reflecting concern about the stability of

the financial markets generally and the strength of counterparties, many lenders and institutional investors have ceased to provide funding to even the most credit-worthy borrowers. This market turmoil and tightening of credit have led to an increased level of commercial and consumer delinquencies, lack of consumer confidence, increased market volatility and widespread reduction of business activity generally.

The resulting economic pressures on consumers and businesses and the lack of confidence in the financial markets have adversely affected Stifel’s business, financial condition and results of operations. Despite recent improvements in market conditions, a potential future decline in these conditions would likely exacerbate the adverse effects of these difficult market conditions on Stifel and others in the financial services industry. It is difficult to predict how long these uncertain market and economic conditions and the accompanying recession will continue, whether the global credit crisis will cause market and economic conditions to continue to deteriorate, and which of Stifel’s markets, products and businesses will continue to be adversely affected and to what degree. Stifel may have impairment losses if events or changes in circumstances occur which may reduce the fair value of an asset below its carrying amount. As a result, these conditions could adversely affect Stifel’s financial condition and results of operations. In addition, Stifel may be subject to increased regulatory scrutiny and litigation due to these issues and events.

A significant portion of Stifel’s revenue is derived from commissions, margin interest revenue, principal transactions, asset management and service fees, and investment banking fees. Accordingly, severe market fluctuations, weak economic conditions, a decline in stock prices, trading volumes, or liquidity could have an adverse affect on Stifel’s profitability. Continued or further credit dislocations or sustained market downturns may result in a decrease in the volume of trades Stifel executes for its clients, a decline in the value of securities Stifel holds in inventory as assets, and reduced investment banking revenues. Poor economic conditions have adversely affected investor confidence, resulting in significant industry-wide declines in the size and number of underwritings and advisory transactions, which could continue to have an adverse effect on Stifel’s revenues.

The fixed income markets are experiencing a period of extreme volatility which has negatively impacted market liquidity conditions. As a result, fixed income instruments are experiencing liquidity issues, increased price volatility, credit downgrades, and increased likelihood of default. In addition to being hard to dispose of, securities that are less liquid are also more difficult to value. Domestic and international equity markets have also been experiencing heightened volatility and turmoil, and as a result issuers that have exposure to the real estate, mortgage and credit markets, including banks and broker-dealers, have been particularly affected. These events and the continuing market upheavals may have an adverse effect on Stifel. In the event of a sustained market downturn, Stifel’s results of operations could be adversely affected by those factors in many ways. Stifel’s revenues are likely to decline in such circumstances and, if it was unable to reduce expenses at the same pace, Stifel’s profit margins would erode. Even in the absence of a sustained market downturn, Stifel is exposed to substantial risk of loss due to market volatility.

In addition, declines in the market value of securities generally result in a decline in revenues from fees based on the asset values of client portfolios, in the failure of buyers and sellers of securities to fulfill their settlement obligations, and in the failure of Stifel’s clients to fulfill their credit and settlement obligations. During market downturns, Stifel’s counterparties may be less likely to complete transactions. Also, Stifel permits its clients to purchase securities on margin. During periods of steep declines in securities prices, the value of the collateral securing client accounts’ margin purchases may drop below the amount of the purchaser’s indebtedness. If the clients are unable to provide additional collateral for these loans, Stifel may lose money on these margin transactions. This may cause Stifel to incur additional expenses defending or pursuing claims or litigation related to counterparty or client defaults.

In addition, in certain of the transactions Stifel is required to post collateral to secure its obligations to the counterparties. In the event of a bankruptcy or insolvency proceeding involving such counterparties, Stifel may experience delays in recovering its assets posted as collateral or may incur a loss to the extent that the counterparty was holding collateral in excess of its obligation to such counterparty. There is no assurance that any such losses would not materially and adversely affect Stifel’s business, financial condition and results of operations.

Recent legislative and regulatory actions, and any such future actions, to address the current liquidity and credit crisis in the financial industry may significantly affect Stifel’s financial condition, results of operation, liquidity or stock price.

Recent economic conditions, particularly in the financial markets, as well as the effect of the change of administration in the White House, have resulted in government regulatory agencies and political bodies placing increased focus on and scrutiny of the financial services industry. In addition to the U.S. Treasury Department’s Capital Purchase Program (in which Stifel has not participated), under the Troubled Asset Relief Program announced last fall and the new Capital Assistance Program announced in the spring (in which Stifel has not participated), the U.S. Government has taken steps that include enhancing the liquidity support available to financial institutions, establishing a commercial paper funding facility, temporarily guaranteeing money market funds and certain types of debt issuances, and increasing insurance on bank deposits, and the U.S. Congress, through the Emergency Economic Stabilization Act of 2008, and the American Recovery and Reinvestment Act of 2009 have imposed a number of restrictions and limitations on the operations of financial services firms participating in the federal programs. Further, there is no assurance that these programs individually or collectively will have beneficial effects in the credit markets, will address credit or liquidity issues of companies that participate in the programs or will reduce volatility or uncertainty in the financial markets. The failure of these programs to have their intended effects could have a material adverse effect on the financial markets, which in turn could materially and adversely affect Stifel’s financial condition, results of operations, or liquidity.

Stifel anticipates new legislative and regulatory initiatives over the next several years, including many focused specifically on the financial services industry that could further substantially increase regulation of the financial services industry and impose restrictions on the operations and general ability of firms within the industry to conduct business consistent with historical practices. Stifel cannot predict the substance or impact of pending or future legislation, regulation or the application thereof. Compliance with such current and potential regulation and scrutiny may significantly increase Stifel’s costs, impede the efficiency of its internal business processes, require it to increase its regulatory capital, impact how it compensates and incents its associates and limit its ability to pursue business opportunities in an efficient manner.

Lack of sufficient liquidity or access to capital could impair Stifel’s business and financial condition.

Liquidity is essential to Stifel’s business. If Stifel has insufficient liquid assets, it will be forced to curtail its operations, and its business will suffer. Stifel’s assets, consisting mainly of cash or assets readily convertible into cash, are its principal sources of liquidity. These assets are financed primarily by Stifel’s equity capital, debentures to trusts, client credit balances, short-term bank loans, proceeds from securities lending, customer deposits and other payables. Stifel currently finances its client accounts and firm trading positions through ordinary course borrowings at floating interest rates from various banks on a demand basis and securities lending, with company-owned and client securities pledged as collateral. Changes in securities market volumes, related client borrowing demands, underwriting activity, and levels of securities inventory affect the amount of Stifel’s financing requirements.

The capital and credit markets have been experiencing volatility and disruption since early 2008, and reached unprecedented levels during the first quarter of 2009. In some cases, the markets have produced downward pressure on stock prices and credit availability for certain issuers without regard to those issuers’ underlying financial strength. Despite recent improvements in market conditions, if market disruption and volatility return to the unprecedented levels reached in early 2009 or worsen, there can be no assurance that Stifel will not experience an adverse effect, which may be material to its business, financial condition and results of operations and affect its ability to access capital.

Stifel’s liquidity requirements may change in the event it needs to raise more funds than anticipated to increase inventory positions, support more rapid expansion, develop new or enhanced services and products, acquire technologies, or respond to other unanticipated liquidity requirements. Stifel relies exclusively on

financing activities and distributions from its subsidiaries for funds to implement its business and growth strategies. Net capital rules or the borrowing arrangements of Stifel’s subsidiaries, as well as the earnings, financial condition, and cash requirements of its subsidiaries, may each limit distributions to Stifel from its subsidiaries.

In the event existing internal and external financial resources do not satisfy Stifel’s needs, it may have to seek additional outside financing. The availability of outside financing will depend on a variety of factors, such as market conditions, the general availability of credit, the volume of trading activities, the overall availability of credit to the financial services industry, credit ratings, and credit capacity, as well as the possibility that lenders could develop a negative perception of its long-term or short-term financial prospects if Stifel incurred large trading losses or if the level of its business activity decreased due to a market downturn or otherwise. Stifel currently does not have a credit rating, which could adversely affect its liquidity and competitive position by increasing its borrowing costs and limiting access to sources of liquidity that require a credit rating as a condition to providing funds.

Current trends in the global financial markets could cause significant fluctuations in Stifel’s stock price.

Stock markets in general, and stock prices of financial services firms in particular, including Stifel, have in recent years, and particularly in the latter part of 2008 continuing through the first quarter of 2009, experienced significant price and volume fluctuations. The market price of Stifel’s common stock may continue to be subject to similar market fluctuations which may be unrelated to its operating performance or prospects, and increased volatility could result in an overall decline in the market price of its common stock. Factors that could significantly impact the volatility of Stifel’s stock price include:

•

developments in Stifel’s business or in the financial sector generally, including the effect of direct governmental action in the financial markets generally and with respect to financial institutions in particular;

•

regulatory changes affecting Stifel’s operations;

•

the operating and securities price performance of companies that investors consider to be comparable to Stifel;

•

announcements of strategic developments, acquisitions and other material events by Stifel or its competitors; and

•

changes in global financial markets and global economies and general market conditions, such as interest or foreign exchange rates, stock, commodity or asset valuations or volatility.

Significant declines in the market price of Stifel’s common stock or failure of the market price of its common stock to increase could harm its ability to recruit and retain key employees, including its executives and financial advisors and other key professional employees and those who have joined Stifel from companies Stifel has acquired, reduce its access to debt or equity capital and otherwise harm its business or financial condition. In addition, Stifel may not be able to use its common stock effectively as consideration in connection with future acquisitions.

Stifel faces intense competition in its industry.

All aspects of Stifel’s business and of the financial services industry in general are intensely competitive. Stifel expects competition to continue and intensify in the future. Stifel’s business will suffer if it does not compete successfully. Stifel competes on the basis of a number of factors, including the quality of its personnel, the quality and selection of its investment products and services, pricing (such as execution pricing and fee levels), and reputation. Because of market unrest and increased government intervention, the financial services industry has recently undergone significant consolidation, which has further concentrated equity capital and other financial resources in the industry and further increased competition. Many of Stifel’s competitors use their significantly

greater financial capital and scope of operations to offer their customers more products and services, broader research capabilities, access to international markets, and other products and services not currently offered by Stifel.

Stifel competes directly with national full-service broker-dealers, investment banking firms, and commercial banks and, to a lesser extent, with discount brokers and dealers and investment advisors. In addition, Stifel faces competition from new entrants into the market and increased use of alternative sales channels by other firms. Domestic commercial banks and investment banking boutique firms have entered the broker-dealer business, and large international banks have begun serving Stifel’s markets as well. Legislative and regulatory initiatives intended to ease restrictions on the sale of securities and underwriting activities by commercial banks have increased competition. Stifel also competes indirectly for investment assets with insurance companies, real estate firms, hedge funds and others. This increased competition could cause Stifel’s business to suffer.

The industry of electronic and/or discount brokerage services is continuing to develop. Increased competition from firms using new technology to deliver these products and services may materially and adversely affect Stifel’s operating results and financial position. Competitors offering internet-based or other electronic brokerage services may have lower costs and offer their customers more attractive pricing and more convenient services than Stifel does. In addition, Stifel anticipates additional competition from underwriters who conduct offerings of securities through electronic distribution channels, bypassing financial intermediaries such as Stifel altogether. These and other competitive pressures may have an adverse affect on Stifel’s competitive position and, as a result, Stifel’s operations, financial condition and liquidity.

Regulatory and legal developments could adversely affect Stifel’s business and financial condition.

The financial services industry is subject to extensive regulation and broker-dealers and investment advisors are subject to regulations covering all aspects of the securities business. Stifel could be subject to civil liability, criminal liability, or sanctions, including revocation of its subsidiaries’ registrations as investment advisors or broker-dealers, revocation of the licenses of its financial advisors, censures, fines, or a temporary suspension or permanent bar from conducting business, if Stifel violates such laws or regulations. Any such liability or sanction could have a material adverse effect on Stifel’s business, financial condition and prospects. Moreover, Stifel’s independent contractor subsidiaries, CSA and SN Ltd, give rise to a potentially higher risk of noncompliance because of the nature of the independent contractor relationships involved.

As a bank holding company, Stifel is subject to regulation by the Federal Reserve. Stifel Bank is subject to regulation by the FDIC. As a result, Stifel is subject to a risk of loss resulting from failure to comply with banking laws. The recent economic and political environment has caused regulators to increase their focus on the regulation of the financial services industry, including introducing proposals for new legislation. Stifel is unable to predict whether any of these proposals will be implemented and in what form, or whether any additional or similar changes to statutes or regulations, including the interpretation or implementation thereof, will occur in the future. Any such action could affect Stifel in substantial and unpredictable ways and could have an adverse effect on its business, financial condition and results of operations. Stifel also may be adversely affected as a result of changes in federal, state or foreign tax laws, or by changes in the interpretation or enforcement of existing laws and regulations. For additional information regarding Stifel’s regulatory environment and its approach to managing regulatory risk, see Item 1 “Business—Regulation” and Item 7A “Quantitative and Qualitative Disclosures About Market Risk” in Stifel’s Annual Report on Form 10-K for the year ended December 31, 2009, filed with the SEC on February 26, 2010 and Part I, Item 3 “Quantitative and Qualitative Disclosures About Market Risk” in Stifel’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2010, filed with the SEC on April 30, 2010.

Stifel and its subsidiaries are named in and subject to various proceedings and claims arising primarily from its securities business activities, including lawsuits, arbitration claims, class actions, and regulatory matters. Some of these claims seek substantial compensatory, punitive, or indeterminate damages. Stifel and its subsidiaries are also involved in other reviews, investigations and proceedings by governmental and self-

regulatory organizations regarding its business which may result in adverse judgments, settlements, fines, penalties, injunctions and other relief.

The regulatory investigations include inquiries from the SEC, FINRA and several state regulatory authorities requesting information concerning Stifel’s activities with respect to auction rate securities (“ARS”) and in connection with certain investments made by other post-employment benefit (“OPEB”) trusts formed by five Southwestern Wisconsin school districts.

In turbulent economic times such as these, the volume of claims and amount of damages sought in litigation and regulatory proceedings against financial institutions has historically increased. These risks include potential liability under securities and other laws for alleged materially false or misleading statements made in connection with securities offerings and other transactions, issues related to the suitability of Stifel’s investment advice based on its clients’ investment objectives, and potential liability for other advice Stifel provides to participants in strategic transactions. Legal actions brought against Stifel may result in judgments, settlements, fines, penalties or other results, any of which could materially adversely affect Stifel’s business, financial condition or results of operations, or cause it serious reputational harm.

For a discussion of Stifel’s legal matters, including ARS and OPEB litigation, and its approach to managing legal risk, see Item 3, “Legal Proceedings” and Item 7A, “Quantitative and Qualitative Disclosures About Market Risk” in Stifel’s Annual Report on Form 10-K for the year ended December 31, 2009, filed with the SEC on February 26, 2010 and Part II, Item 1, “Legal Proceedings” and Part I, Item 3 “Quantitative and Qualitative Disclosures About Market Risk” in Stifel’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2010, filed with the SEC on April 30, 2010.

Failure to comply with regulatory capital requirements would significantly harm Stifel’s business.

The SEC requires broker-dealers to maintain adequate regulatory capital in relation to their liabilities and the size of their customer business. These rules require Stifel Nicolaus and CSA, Stifel’s broker-dealer subsidiaries, to maintain a substantial portion of their assets in cash or highly liquid investments. Failure to maintain the required net capital may subject Stifel’s broker-dealer subsidiaries to limitations on their activities, or in extreme cases, suspension or revocation of their registration by the SEC and suspension or expulsion by FINRA and other regulatory bodies, and, ultimately, liquidation. Stifel’s international subsidiary, SN Ltd, is subject to similar limitations under applicable laws in the United Kingdom. Failure to comply with the net capital rules could have material and adverse consequences, such as:

•

limiting Stifel’s operations that require intensive use of capital, such as underwriting or trading activities; or

•

restricting Stifel from withdrawing capital from its subsidiaries, even where its broker-dealer subsidiaries have more than the minimum amount of required capital. This, in turn, could limit Stifel’s ability to implement its business and growth strategies, pay interest on and repay the principal of its debt and/or repurchase its shares.

In addition, a change in the net capital rules or the imposition of new rules affecting the scope, coverage, calculation, or amount of net capital requirements, or a significant operating loss or any large charge against net capital, could have similar adverse effects. In addition, as a bank holding company, Stifel and its bank subsidiary are subject to various regulatory requirements administered by the federal banking agencies, including capital adequacy requirements pursuant to which Stifel and its bank subsidiary must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. See Item 1 “Business—Regulation” for additional information regarding Stifel’s regulatory environment in Stifel’s Annual Report on Form 10-K for the year ended December 31, 2009, filed with the SEC on February 26, 2010.

Stifel has experienced significant pricing pressure in areas of its business, which may impair its revenues and profitability.

In recent years, Stifel’s business has experienced significant pricing pressures on trading margins and commissions in fixed income and equity trading. In the fixed income market, regulatory requirements have resulted in greater price transparency, leading to increased price competition and decreased trading margins. In the equity market, Stifel has experienced increased pricing pressure from institutional clients to reduce commissions, and this pressure has been augmented by the increased use of electronic and direct market access trading, which has created additional competitive downward pressure on trading margins. The trend towards using alternative trading systems is continuing to grow, which may result in decreased commission and trading revenue, reduce Stifel’s participation in the trading markets and its ability to access market information, and lead to the creation of new and stronger competitors. Institutional clients also have pressured financial services firms to alter “soft dollar” practices under which brokerage firms bundle the cost of trade execution with research products and services. Some institutions are entering into arrangements that separate (or “unbundle”) payments for research products or services from sales commissions. These arrangements have increased the competitive pressures on sales commissions and have affected the value Stifel’s clients place on high-quality research. Additional pressure on sales and trading revenue may impair the profitability of Stifel’s business. Moreover, Stifel’s inability to reach agreement regarding the terms of unbundling arrangements with institutional clients who are actively seeking such arrangements could result in the loss of those clients, which would likely reduce Stifel’s institutional commissions. Stifel believes that price competition and pricing pressures in these and other areas will continue as institutional investors continue to reduce the amounts they are willing to pay, including by reducing the number of brokerage firms they use, and some of Stifel’s competitors seek to obtain market share by reducing fees, commissions or margins.

Stifel’s underwriting and market-making activities place its capital at risk.

Stifel may incur losses and be subject to reputational harm to the extent that, for any reason, Stifel is unable to sell securities it purchased as an underwriter at the anticipated price levels. As an underwriter, Stifel also is subject to heightened standards regarding liability for material misstatements or omissions in prospectuses and other offering documents relating to offerings Stifel underwrites. As a market maker, Stifel may own large positions in specific securities, and these undiversified holdings concentrate the risk of market fluctuations and may result in greater losses than would be the case if Stifel’s holdings were more diversified.

Stifel’s ability to attract, develop and retain highly skilled and productive employees is critical to the success of its business.

Stifel’s people are its most valuable asset. Stifel’s ability to develop and retain its client base and to obtain investment banking and advisory engagements depends upon the reputation, judgment, business generation capabilities and project execution skills of highly skilled and often highly specialized employees, including Stifel’s executive officers. The unexpected loss of services of any of these key employees and executive officers, or the inability to recruit and retain highly qualified personnel in the future, could have an adverse effect on Stifel’s business and results of operations.

Financial advisors typically take their clients with them when they leave Stifel to work for a competitor. From time to time, in addition to financial advisors, Stifel has lost equity research, investment banking, public finance, institutional sales and trading professionals, and in some cases, clients, to its competitors.

Competition for personnel within the financial services industry is intense. The cost of retaining skilled professionals in the financial services industry has escalated considerably, as competition for these professionals has intensified. Employers in the industry are increasingly offering guaranteed contracts, upfront payments, and increased compensation. These can be important factors in a current employee’s decision to leave Stifel as well as a prospective employee’s decision to join Stifel. As competition for skilled professionals in the industry increases, Stifel may have to devote more significant resources to attracting and retaining qualified personnel. In

particular, Stifel’s financial results may be adversely affected by the amortization costs incurred by Stifel in connection with the upfront loans it offers to financial advisors.

Moreover, companies in Stifel’s industry whose employees accept positions with competitors frequently claim that those competitors have engaged in unfair hiring practices. Stifel is currently subject to several such claims and may be subject to additional claims in the future as it seeks to hire qualified personnel, some of whom may currently be working for Stifel’s competitors. Some of these claims may result in material litigation. Stifel could incur substantial costs in defending itself against these claims, regardless of their merits. Such claims could also discourage potential employees who currently work for Stifel competitors from joining Stifel.

Stifel may recruit financial advisors, make strategic acquisitions of businesses, or divest or exit existing businesses, which could cause it to incur unforeseen expenses and have disruptive effects on its business and may strain its resources.

Stifel’s growth strategies have included, and will continue to include, the recruitment of financial advisors and strategic acquisitions. Since December 2005, Stifel has completed six acquisitions: LM Capital Markets in 2005, the private client business of MJSK in 2006, Ryan Beck and First Service in 2007, Butler Wick in 2008 and certain branches from the UBS Wealth Management Americas branch network in 2009. These acquisitions, as well as the current proposed acquisition of Thomas Weisel Partners, or any other acquisition that Stifel determines to pursue will be accompanied by a number of risks. The growth of Stifel’s business and expansion of its client base has strained, and may continue to strain, Stifel management and administrative resources. Costs or difficulties relating to such transactions, including integration of financial advisors, and other employees, products and services, technology systems, accounting systems and management controls, may be greater than expected. Unless offset by a growth of revenues, the costs associated with these investments will reduce Stifel’s operating margins. In addition, because, as noted above, financial professionals typically take their clients with them when they leave, if key employees or other senior management personnel of the businesses Stifel has acquired determine that they do not wish to remain with Stifel over the long term or at all, Stifel would not inherit portions of the client base of those businesses, which would reduce the value of those acquisitions to Stifel.

In addition to past growth, Stifel cannot assure investors that it will be able to manage its future growth successfully. The inability to do so could have a material adverse effect on Stifel’s business, financial condition and results of operations. After Stifel announces or completes any given acquisition in the future, including the current proposed acquisition of Thomas Weisel Partners, Stifel’s share price could decline if investors view the transaction as too costly or unlikely to improve Stifel’s competitive position. Stifel may be unable to retain key personnel after any such transaction, and the transaction may impair relationships with customers and business partners. These difficulties could disrupt Stifel’s ongoing business, increase its expenses and adversely affect its operating results and financial condition. In addition, Stifel may be unable to achieve anticipated benefits and synergies from any such transaction as fully as expected or within the expected time frame. Divestitures or elimination of existing businesses or products could have similar effects.

Moreover, to the extent Stifel pursues increased expansion to different geographic markets or grow generally through additional strategic acquisitions, Stifel cannot assure you that it will identify suitable acquisition candidates, that acquisitions will be completed on acceptable terms or that it will be able to successfully integrate the operations of any acquired business into its existing business. Such acquisitions could be of significant size and involve firms located in regions of the United States where Stifel does not currently operate, or internationally. To acquire and integrate a separate organization would further divert management attention from other business activities. This diversion, together with other difficulties Stifel may encounter in integrating an acquired business, could have a material adverse effect on Stifel’s business, financial condition and results of operations. In addition, Stifel may need to borrow money to finance acquisitions, which would increase Stifel’s leverage. Such funds might not be available on terms as favorable to Stifel as its current borrowing terms or at all.

The rapid growth of Stifel Bank may expose Stifel to increased operational risk, credit risk and sensitivity to market interest rates along with increased regulation, examinations and supervision by regulators.

Stifel has experienced rapid growth in the balance sheet of Stifel Bank. The increase is primarily attributable to the growth in securities-based loans and deposits as a result of the UBS acquisition. Although Stifel’s stock-secured loans are collateralized by assets held in brokerage accounts, Stifel is exposed to some credit and operational risk associated with these loans. Stifel describes some of the integration related operational risks associated with its recent acquisitions above, which includes many of the same risks related to the growth of Stifel Bank. With the increase in deposits, and resulting liquidity, Stifel has been able to expand its investment portfolio, primarily with government agency securities. In addition, Stifel Bank has significantly grown its mortgage banking business. Although Stifel believes it has adequate underwriting policies in place, there are inherent risks associated with the mortgage banking business. For further discussion of Stifel’s segments, including its Stifel Bank reporting unit, see Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Segment Analysis” in Stifel’s Annual Report on Form 10-K for the year ended December 31, 2009, filed with the SEC on February 26, 2010 and Part I, Item 2 “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Segment Analysis” in Stifel’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2010, filed with the SEC on April 30, 2010.

As a result of the high percentage of Stifel’s assets and liabilities that are in the form of interest-bearing or interest-related instruments, Stifel is more sensitive to changes in interest rates, in the shape of the yield curve or in relative spreads between market interest rates.

The monetary, tax and other policies of the government and its agencies, including the Federal Reserve, have a significant impact on interest rates and overall financial market performance. An important function of the Federal Reserve is to regulate the national supply of bank credit and market interest rates. The actions of the Federal Reserve influence the rates of interest that Stifel charges on loans and that Stifel pays on borrowings and interest-bearing deposits, which may also affect the value of its on-balance sheet and off-balance sheet financial instruments. Stifel cannot predict the nature or timing of future changes in monetary, tax and other policies or the effect that they may have on its activities and results of operations.

In addition, Stifel Bank is heavily regulated at the state and federal level. This regulation is to protect depositors, federal deposit insurance funds, consumers and the banking system as a whole, not Stifel’s stockholders. Federal and state regulations can significantly restrict Stifel’s businesses, and Stifel is subject to various regulatory actions which could include fines, penalties or other sanctions for violations of laws and regulatory rules if Stifel is ultimately found to be out of compliance.

Stifel’s risk management policies and procedures may leave it exposed to unidentified or unanticipated risk.

Stifel seeks to manage, monitor and control its operational, legal and regulatory risk through operational and compliance reporting systems, internal controls, management review processes and other mechanisms; however, there can be no assurance that its procedures will be fully effective. Further, Stifel’s risk management methods are based on an evaluation of information regarding markets, clients and other matters that are based on assumptions that may no longer be accurate. In addition, Stifel has undergone significant growth in recent years. A failure to adequately manage Stifel’s growth, or to effectively manage its risk, could materially and adversely affect Stifel’s business and financial condition. Stifel must also address potential conflicts of interest that arise in its business. Stifel has procedures and controls in place to address conflicts of interest, but identifying and managing potential conflicts of interest can be complex and difficult and Stifel’s reputation could be damaged if it fails, or appears to fail, to deal appropriately with conflicts of interest. See Item 7A, “Quantitative and Qualitative Disclosures About Market Risk” in Stifel’s Annual Report on Form 10-K for the year ended December 31, 2009, filed with the SEC on February 26, 2010, and Part I, Item 3, “Quantitative and Qualitative Disclosures About Market Risk” in Stifel’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2010, filed with the SEC on April 30, 2010, for more information on how Stifel monitors and manages market and certain other risks.

Stifel continually encounters technological change, and Stifel may have fewer resources than many of its competitors to continue to invest in technological improvements, which are important to attract and retain financial advisors.

Stifel relies extensively on electronic data processing and communications systems. Adapting or developing its technology systems to meet new regulatory requirements, client needs and industry demands is critical for Stifel’s business. Introduction of new technologies present new challenges on a regular basis. In addition to better serving its clients, the effective use of technology increases efficiency and enables Stifel to reduce costs. Stifel’s future success will depend in part upon its ability to successfully maintain and upgrade its systems and its ability to address the needs of its clients by using technology to provide products and services that will satisfy their demands for convenience, as well as to create additional efficiencies in its operations. Many of Stifel’s competitors have substantially greater resources to invest in technological improvements. Stifel cannot assure you that it will be able to effectively upgrade its systems, implement new technology-driven products and services or be successful in marketing these products and services to its clients.

Stifel’s operations and infrastructure and those of the service providers upon which it relies may malfunction or fail.

Stifel’s business is highly dependent on its ability to process, on a daily basis, a large number of transactions across diverse markets, and the transactions Stifel processes have become increasingly complex. The inability of Stifel’s systems to accommodate an increasing volume of transactions could also constrain its ability to expand its businesses. If any of these systems do not operate properly or are disabled, or if there are other shortcomings or failures in Stifel’s internal processes, people or systems, Stifel could suffer impairments, financial loss, a disruption of its businesses, liability to clients, regulatory intervention or reputational damage.

Stifel has outsourced certain aspects of its technology infrastructure, including trade processing, data centers, disaster recovery systems, and wide area networks, as well as market data servers, which constantly broadcast news, quotes, analytics, and other important information to the desktop computers of its financial advisors. Stifel contracts with other vendors to produce, batch, and mail its confirmations and customer reports. Stifel is dependent on its technology providers to manage and monitor those functions. A disruption of any of the outsourced services would be out of Stifel’s control and could negatively impact its business. Stifel has experienced disruptions on occasion, none of which has been material to its operations and results. However, there can be no guarantee that future disruptions with these providers will not occur.

Stifel also faces the risk of operational failure, termination or capacity constraints of any of the clearing agents, exchanges, clearing houses or other financial intermediaries it uses to facilitate its securities transactions. Any such failure or termination could adversely affect Stifel’s ability to effect transactions and to manage its exposure to risk.

Stifel’s operations also rely on the secure processing, storage and transmission of confidential and other information in its computer systems and networks. Although Stifel takes protective measures and endeavor to modify them as circumstances warrant, its computer systems, software and networks may be vulnerable to unauthorized access, computer viruses or other malicious code and other events that could have a security impact. If one or more of such events occur, this could jeopardize Stifel’s or its clients’ or counterparties’ confidential and other information processed, stored in and transmitted through its computer systems and networks, or otherwise cause interruptions or malfunctions in Stifel’s, its clients’, its counterparties’ or third parties’ operations which could result in significant losses or reputational damage. Stifel may be required to expend significant additional resources to modify its protective measures, to investigate and remediate vulnerabilities or other exposures or to make required notifications, and Stifel may be subject to litigation and financial losses that are either not insured or not fully covered through any insurance maintained by Stifel.

Stifel may suffer losses if its reputation is harmed.

Stifel’s ability to attract and retain customers and employees may be adversely affected to the extent its reputation is damaged. If Stifel fails to deal with, or appears to fail to deal with, various issues that may give rise to reputational risk, Stifel could harm its business prospects. These issues include, but are not limited to, appropriately dealing with potential conflicts of interest, legal and regulatory requirements, ethical issues, money-laundering, privacy, record-keeping, sales and trading practices, and the proper identification of the legal, reputational, credit, liquidity and market risks inherent in Stifel’s products. Failure to appropriately address these issues could also give rise to additional legal risk to Stifel, which could, in turn, increase the size and number of claims and damages asserted against Stifel or subject it to regulatory enforcement actions, fines, and penalties.

Stifel’s current stockholders may experience dilution in their holdings if Stifel issues additional shares of common stock as a result of future offerings or acquisitions where Stifel uses its common stock.

As part of Stifel’s business strategy, Stifel may continue to seek opportunities for growth through strategic acquisitions, in which Stifel may consider issuing equity securities as part of the consideration. Additionally, Stifel may obtain additional capital through the public or private sale of equity securities. If Stifel sells equity securities, the value of its common stock could experience dilution. Furthermore, these securities could have rights, preferences and privileges more favorable than those of the common stock. Moreover, if Stifel issues additional shares of common stock in connection with future acquisitions or as a result of a financing, investors ownership interest in Stifel will be diluted.

The issuance of any additional shares of common stock or securities convertible into or exchangeable for common stock or that represent the right to receive common stock, or the exercise of such securities, could be substantially dilutive to stockholders of Stifel’s common stock. Holders of Stifel’s shares of common stock have no preemptive rights that entitle holders to purchase their pro rata share of any offering of shares of any class or series and, therefore, such sales or offerings could result in increased dilution to Stifel’s stockholders. The market price of Stifel’s common stock could decline as a result of sales of shares of Stifel’s common stock or securities convertible into or exchangeable for common stock.

Stifel is subject to an increased risk of legal proceedings, which may result in significant losses to Stifel that it cannot recover. Claimants in these proceedings may be customers, employees, or regulatory agencies, among others, seeking damages for mistakes, errors, negligence or acts of fraud by Stifel’s employees.

Many aspects of Stifel’s business subject it to substantial risks of potential liability to customers and to regulatory enforcement proceedings by state and federal regulators. Participants in the financial services industry face an increasing amount of litigation and arbitration proceedings. Dissatisfied clients regularly make claims against broker-dealers and their employees for, among others, negligence, fraud, unauthorized trading, suitability, churning, failure to supervise, breach of fiduciary duty, employee errors, intentional misconduct, unauthorized transactions by financial advisors or traders, improper recruiting activity, and failures in the processing of securities transactions. These types of claims expose Stifel to the risk of significant loss. Acts of fraud are difficult to detect and deter, and while Stifel believes its supervisory procedures are reasonably designed to detect and prevent violations of applicable laws, rules and regulations, Stifel cannot assure investors that its risk management procedures and controls will prevent losses from fraudulent activity. In its role as underwriter and selling agent, Stifel may be liable if there are material misstatements or omissions of material information in prospectuses and other communications regarding underwritten offerings of securities. At any point in time, the aggregate amount of existing claims against Stifel could be material. While Stifel does not expect the outcome of any existing claims against it to have a material adverse impact on its business, financial condition, or results of operations, Stifel cannot assure you that these types of proceedings will not materially and adversely affect Stifel. Stifel does not carry insurance that would cover payments regarding these liabilities, with the exception of fidelity coverage with respect to certain fraudulent acts of its employees. In addition, Stifel’s by-laws provide for the indemnification of its officers, directors, and employees to the maximum extent permitted under Delaware law. In the future, Stifel may be the subject of indemnification assertions under these documents by its officers,

directors or employees who have or may become defendants in litigation. These claims for indemnification may subject Stifel to substantial risks of potential liability. For a discussion of Stifel’s legal matters (including ARS and OPBE litigation) and Stifel’s approach to managing legal risk, see Item 3, “Legal Proceedings” in Stifel’s Annual Report on Form 10-K for the year ended December 31, 2009, filed with the SEC on February 26, 2010 and Part II, Item 1, “Legal Proceedings” in Stifel’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2010, filed with the SEC on April 30, 2010.

In addition to the foregoing financial costs and risks associated with potential liability, the costs of defending litigation and claims has increased over the last several years. The amount of outside attorneys’ fees incurred in connection with the defense of litigation and claims could be substantial and might materially and adversely affect Stifel’s results of operations as such fees occur. Securities class action litigation in particular is highly complex and can extend for a protracted period of time, thereby substantially increasing the costs incurred to resolve this litigation.

Misconduct by Stifel’s employees or by the employees of its business partners could harm Stifel and is difficult to detect and prevent.

There have been a number of highly publicized cases involving fraud or other misconduct by employees in the financial services industry in recent years, and Stifel runs the risk that employee misconduct could occur at Stifel. For example, misconduct could involve the improper use or disclosure of confidential information, which could result in regulatory sanctions and serious reputational or financial harm. It is not always possible to deter misconduct and the precautions Stifel takes to detect and prevent this activity may not be effective in all cases. Stifel’s ability to detect and prevent misconduct by entities with which it does business may be even more limited. Stifel may suffer reputational harm for any misconduct by its employees or those entities with which it does business.

Provisions in Stifel’s certificate of incorporation and bylaws and of Delaware law may prevent or delay an acquisition of Stifel, which could decrease the market value of Stifel’s common stock.

Stifel’s articles of incorporation and bylaws and Delaware law contain provisions that are intended to deter abusive takeover tactics by making them unacceptably expensive to prospective acquirors and to encourage prospective acquirors to negotiate with Stifel’s board of directors rather than to attempt a hostile takeover. These provisions include giving the board of directors authority to issue, without further action or approval of the stockholders, additional shares of common stock to the public, thereby increasing the number of shares that would have to be acquired to effect a change in control of Stifel. Delaware law also imposes some restrictions on mergers and other business combinations between Stifel and any holder of 15% or more of its outstanding common stock. Stifel believes these provisions protect its stockholders from coercive or otherwise unfair takeover tactics by requiring potential acquirors to negotiate with Stifel’s board of directors and by providing Stifel’s board of directors with more time to assess any acquisition proposal. These provisions are not intended to make Stifel immune from takeovers. However, these provisions apply even if the offer may be considered beneficial by some stockholders and could delay or prevent an acquisition that Stifel’s board of directors determines is not in the best interests of Stifel and its stockholders.

THE THOMAS WEISEL PARTNERS GROUP, INC. ANNUAL MEETING

Date, Time and Place; Attending the Annual Meeting

The Annual Meeting will take place on June 22, 2010, at One Montgomery Street, 35^th Floor, San Francisco, California, commencing at 8:00 a.m., Pacific time. Check in will begin at 7:30 a.m., Pacific time, and you should allow ample time for check-in procedures.

Instructions for attending the Annual Meeting if you hold exchangeable shares are included in the Notice to Exchangeable Shareholders that accompanies this proxy statement/prospectus.

Matters to be Considered

At the Annual Meeting, Thomas Weisel Partners stockholders will be asked to vote on the following proposals:

•

To approve and adopt the merger agreement and approve the merger contemplated by the merger agreement;

•

To ratify the appointment of Deloitte & Touche LLP as Thomas Weisel Partners’ independent registered accounting firm for 2010; and

•

To conduct any other business that properly comes before the Annual Meeting or any adjournment or postponement of the Annual Meeting.

A copy of the merger agreement is attached to this proxy statement/prospectus as Annex A. You are encouraged to read the merger agreement and the other information contained in this proxy statement/prospectus (including the documents incorporated by reference into this proxy statement/prospectus) carefully before deciding how to vote.

Record Date; Stock Entitled to Vote

Holders of record are entitled to vote (or, in the case of holders of exchangeable shares, direct the trustee to vote as described further below) only if you were a Thomas Weisel Partners stockholder or a holder of exchangeable shares of TWP Acquisition Company (Canada), Inc. as of the close of business on April 30, 2010, the record date, provided that such shares remain outstanding on the date of the meeting.

Each share of Thomas Weisel Partners common stock is entitled to one vote for each matter to be voted on.

In addition, we have issued one share of Thomas Weisel Partners special voting preferred stock, par value $0.01 per share, through which the holders of the exchangeable shares issued by TWP Acquisition Company (Canada), Inc., may exercise voting rights. The Thomas Weisel Partners special voting preferred stock provides a mechanism for holders of exchangeable shares, which are intended to be substantially the voting equivalent of Thomas Weisel Partners common stock, to vote with Thomas Weisel Partners common stock. The share of Thomas Weisel Partners special voting preferred stock is entitled to one vote for each exchangeable share outstanding, excluding shares held by Thomas Weisel Partners or any person directly or indirectly controlled by or under common control with Thomas Weisel Partners, on all matters on which Thomas Weisel Partners common stock is entitled to vote. CIBC Mellon Trust Company, the trustee holder of Thomas Weisel Partners special voting preferred stock, has the right to cast a number of votes equal to the number of then-outstanding exchangeable shares. The trustee will only cast a number of votes equal to the number of exchangeable shares as to which it has received a voting instruction card from the owners of record of the exchangeable shares (other than Thomas Weisel Partners and any person directly or indirectly controlled by or under common control with Thomas Weisel Partners), as of the record date. Instructions for voting and revocation of voting instructions, as well as instructions for attending the Annual Meeting if you hold exchangeable shares, are included in the Notice to Exchangeable Shareholders that is being provided to holders of exchangeable shares along with this proxy statement/prospectus.

Quorum

Vote Required

The following are the vote requirements for the various proposals:

•

Approval and Adoption of the Merger Agreement and Approval of the Merger: You may vote “FOR,” “AGAINST” or “ABSTAIN” with respect to the approval and adoption of the merger agreement and approval of the merger. To approve and adopt the merger agreement and approve the merger, the holders of a majority of the voting power of the outstanding shares of Thomas Weisel Partners common stock and Thomas Weisel Partners special voting preferred stock, voting together as a single class, must vote “FOR” the approval and adoption of the merger agreement and the approval of the merger. Because approval is based on the affirmative vote of a majority of the combined voting power of the shares outstanding, your failure to vote or an abstention will have the same effect as a vote against approval and adoption of the merger agreement and against approval of the merger.

•

Election of Directors. You may vote “FOR” or “WITHHOLD” with respect to any or all director nominees. The election of a director requires a plurality of the votes that are cast “FOR” the election of directors. Accordingly, the eight nominees receiving the highest number of “FOR” (among votes properly cast in person or by proxy and entitled to vote) will be elected. A properly executed proxy marked “WITHHOLD” with respect to the election of one or more directors will not be voted with respect to the director or directors indicated, and because there are eight nominees for eight director positions, “WITHHOLD” votes will have no effect on the outcome of the vote for the election of directors.

•

All Other Matters. You may vote “FOR,” “AGAINST” or “ABSTAIN” with respect to all other matters at the Annual Meeting. A majority of the votes cast “FOR” or “AGAINST” each other matter must be voted “FOR” such matter for it to pass. Abstentions are not treated as a vote “FOR” or “AGAINST” a proposal and will have no effect on the outcome of the vote for such proposal.

Abstentions

Voting of Proxies by Holders of Record

If your shares are registered directly in your name with Thomas Weisel Partners’ transfer agent, you are considered the stockholder of record with respect to those shares and this proxy statement/prospectus is being sent directly to you by Thomas Weisel Partners. As a stockholder of record, you have the right to grant your proxy directly to Thomas Weisel Partners or to vote in person at the Annual Meeting. Thomas Weisel Partners has enclosed a proxy card for your use. As a stockholder of record, you may submit a proxy for your shares by using the toll-free number or the Internet website by following the instructions on your proxy card for using these quick, cost-effective and easy methods for submitting proxies. You also may submit a proxy in writing by simply filling out, signing and dating your proxy card and mailing it in the prepaid envelope included with this proxy statement/prospectus. If you submit a proxy by telephone or the Internet website, please do not return your proxy card by mail. You will need to follow the instructions when you submit a proxy using any of these methods to make sure your shares will be voted at the meeting.

If you hold shares through a broker or other nominee, you may instruct your broker or other nominee to vote your shares by following the instructions that the broker or nominee provides to you with these materials. See “—Shares Held in Street Name” below.

You also may vote by submitting a ballot in person if you attend the Annual Meeting. However, we encourage you to submit a proxy by mail by completing your proxy card, by telephone or via the Internet even if you plan to attend the Annual Meeting. You will also need to present photo identification and comply with the other procedures described above in “The Thomas Weisel Partners Annual Meeting—Date, Time and Place; Attending the Annual Meeting” on page 61. Giving a proxy will not affect your right to vote your Thomas Weisel Partners shares if you attend the Annual Meeting and want to vote in person.

Your vote is important. Accordingly, please submit your proxy by telephone, through the Internet or by mail, whether or not you plan to attend the Annual Meeting in person. Proxies must be received by 11:59 p.m., Eastern time, on June 21, 2010.

Shares Held in Street Name

If your shares are held in a brokerage account, bank account or by another nominee, you are considered the beneficial owner of shares held in “street name,” and this proxy statement/prospectus is being forwarded to you by your broker, bank or nominee together with a voting instruction card. As the beneficial owner, you have the

right to direct your broker, bank or other nominee how to vote and are also invited to attend the Annual Meeting. However, since you are not the stockholder of record, you may not vote your shares in person at the Annual Meeting unless you obtain a legal proxy from the broker, bank or nominee that holds your shares, giving you the right to vote the shares instead of the broker, bank or nominee holding your shares. Your broker, bank or nominee has enclosed voting instructions for your use in directing your broker, bank or nominee how to vote your shares.

If you do not provide voting instructions to your broker, your shares will not be voted on any proposal on which your broker does not have discretionary authority to vote. This is called a broker non-vote. In these cases, the broker can register your shares as being present at the meeting for purposes of determining the presence of a quorum but will not be able to vote on those matters for which specific authorization is required. Under the current rules of the NYSE, we believe that brokers do not have discretionary authority to vote on the proposal to approve and adopt the merger agreement and approve the merger or the election of directors, but that the ratification of the appointment of independent auditors is a “routine matter” on which brokers will be permitted to vote any un-voted shares. Accordingly, a broker non-vote will have the same effect as a vote against approval and adoption of the merger agreement and approval of the merger and a “WITHHOLD” vote for the election of directors, but will have no effect on whether the other proposals are approved. Because Thomas Weisel Partners LLC is affiliated with Thomas Weisel Partners, NYSE policy specifies that when Thomas Weisel Partners LLC votes on “routine matters”, it may do so only in the same proportion as all other shares of record are voted with respect to each proposal.

Revocability of Proxies

A proxy submitted through the Internet or by telephone may be revoked by (i) executing a later-dated proxy card that is received prior to 11:59 p.m., Eastern time, on June 21, 2010, (ii) subsequently submitting a new proxy through the Internet or by telephone prior to 11:59 p.m., Eastern time, on June 21, 2010, (iii) attending the Annual Meeting and voting in person or (iv) giving written notice to our Secretary and General Counsel at One Montgomery Street, 37th Floor, San Francisco, California 94104.

PROPOSAL ONE: THE MERGER

The following is a discussion of the proposed merger and the merger agreement. This is a summary only and may not contain all of the information that is important to you. A copy of the merger agreement is attached to this proxy statement/prospectus as Annex A and is incorporated by reference herein. You are urged to read this entire proxy statement/prospectus, including the merger agreement and the documents incorporated by reference into this proxy statement/prospectus, for a more complete understanding of the merger.

Structure of the Merger

Subject to the terms and conditions of the merger agreement and in accordance with Delaware law, Merger Sub will be merged with and into Thomas Weisel Partners, with Thomas Weisel Partners surviving the merger and becoming a wholly-owned subsidiary of Stifel. Upon completion of the merger, each share of Thomas Weisel Partners common stock issued and outstanding immediately prior to the effective time of the merger, except for shares of Thomas Weisel Partners common stock held directly and indirectly by Thomas Weisel Partners and Stifel (which will be canceled if the merger is approved and consummated), will be converted into the right to receive, subject to adjustment under limited circumstances as described below, 0.1364 shares of Stifel common stock. Other than possible adjustments as described in the next paragraph below, the exchange ratio of 0.1364 shares of Stifel common stock is fixed, which means that it will not change between now and the date of the merger, including as a result of a change in the trading price of Stifel common stock or Thomas Weisel Partners common stock or the operating and financial performance of either company. Therefore, the value of the shares of Stifel common stock received by Thomas Weisel Partners stockholders in the merger will depend on the market price of Stifel common stock at the time the merger is completed.

Assuming that the holders of the exchangeable shares approve the Exchangeable Share Amendment, the exchangeable shares will not be converted into other securities as part of the merger. In that case, each exchangeable share will remain outstanding and become exchangeable for 0.1364 shares of Stifel common stock. In the event the Exchangeable Share Amendment is approved, at the effective time of the merger, the one outstanding share of Thomas Weisel Partners special voting preferred stock will be canceled and automatically converted into one share of Stifel special voting preferred stock. The one share of Stifel special voting preferred stock will entitle the holder to that number of votes equal to the number of shares of Stifel common stock issuable upon exchange of the exchangeable shares outstanding from time to time other than exchangeable shares held by Stifel or any person directly or indirectly controlled by or under common control of Stifel. Pursuant to the merger agreement, if the Exchangeable Share Amendment is not approved, Thomas Weisel Partners will take all actions necessary to (a) cause TWP Acquisition Company (Canada), Inc. to exercise its right to redeem all of the outstanding exchangeable shares or (b) acquire or cause TWP Holdings Company (Canada), ULC to acquire all of the outstanding exchangeable shares, and, as a result of the merger, holders of exchangeable shares would receive shares of Stifel common stock. For a further description of what holders of exchangeable shares will receive in the merger, see Annex C, entitled “Supplemental Information for the Holders of Exchangeable Shares.”

Background of the Merger

The Stifel board of directors, together with its senior management, continually reviews, considers and evaluates the securities industry and considers acquisitions on a strategic and opportunistic basis. Over the past several years, Stifel has grown substantially, primarily by completing and successfully integrating a number of

acquisitions, including its acquisitions of the capital markets business of Legg Mason from Citigroup in December 2005; Ryan Beck, a full-service brokerage and investment banking firm, in February 2007; First Service Financial Company, now Stifel Bank & Trust, a St. Louis-based bank, in April 2007; Butler Wick, a privately-held broker-dealer, in December 2008; specified branches from the UBS Wealth Management Americas branch network from UBS Financial Services in the third and fourth quarters of 2009; and Missouri Valley Partners, a St. Louis based investment advisor serving institutional and individual clients, from First Banks in April 2009. The focus of these acquisitions has been to expand Stifel’s client base, the range of financial services and products available to its clients and its geographic reach, all to develop and enhance Stifel’s position as a premier middle-market focused investment bank.

Thomas Weisel Partners continually evaluates strategic opportunities to strengthen its business and to deliver value to its shareholders, in particular by seeking ways to diversify its business and expand its platform to provide opportunities for its investment banking professionals and a wider array of products and services for its clients. As part of this process, Thomas Weisel Partners acquired Westwind Capital, an independent Canadian investment banking boutique at the beginning of 2008 in order to expand geographically and to add important verticals in natural resources and energy.

In September 2009, Thomas W. Weisel, Thomas Weisel Partners’ Chairman and Chief Executive Officer, met with Ronald J. Kruszewski, Stifel’s Chairman, President and Chief Executive Officer, during a dinner in San Francisco. At the meeting, Messrs. Kruszewski and Weisel discussed their respective firms’ platforms and business plans.

Over the course of the next several months, Mr. Weisel and Mr. Kruszewski spoke several times by telephone and met again in New York in early November 2009 accompanied by Lionel Conacher, Thomas Weisel Partners’ President and Chief Operating Officer, and Victor Nesi, a Senior Vice President of Stifel. During these meetings and conversations, the participants discussed the potential strategic and cultural alignment between the two firms as well as potential areas in which the two firms complement one another.

At a regularly scheduled Thomas Weisel Partners board meeting in San Francisco on December 8, 2010, Mr. Weisel and Mr. Conacher updated the Thomas Weisel Partners board as to the initial discussions with Stifel and the strategic rationale behind a possible transaction with Stifel. Mark Fisher, Thomas Weisel Partners’ General Counsel provided the members of the Thomas Weisel Partners Board with background material regarding Stifel following the December board meeting.

On February 26, 2010, at the suggestion of Mr. Weisel, Mr. Kruszewski met with Matthew Barger, Thomas Weisel Partners’ Lead Independent Director, and Mr. Weisel in Sun Valley Idaho. At that meeting, Messrs. Kruszewski, Weisel and Barger discussed Stifel’s and Thomas Weisel Partners’ respective histories, business philosophies and cultures, as well as their strategic view of the future and the strategic value of a combination.

Throughout this period, Stifel reviewed selected materials, based on public information, relating to a potential strategic combination between Stifel and Thomas Weisel Partners.

On March 1, 2010, Stifel and Thomas Weisel Partners entered into a mutual confidentiality agreement.

During March, Shaugn Stanley, Thomas Weisel Partners’ Chief Administrative Officer, provided Stifel with summary financial information regarding Thomas Weisel Partners’ cost structure, compensation model, capitalization and balance sheet.

Mr. Kruszewski met with Mr. Weisel and an investment banking representative from Thomas Weisel Partners in San Francisco on March 22, 2010, at which time further details of a possible transaction were discussed, including the parties’ relative perspectives on valuation of the firms. At that meeting, Mr. Kruszewski

presented a range for a possible exchange ratio for a potential combination of the firms. On that day, Stifel and Thomas Weisel Partners’ amended their confidentiality agreement to provide for mutual non-solicitation covenants. On the next day, Mr. Kruszewski met with Mr. Weisel and over the course of an afternoon met as well as with several members of Thomas Weisel Partners’ executive committee during which the cultural fit between the firms and their respective key employees was discussed as well as potential transaction structure issues.

Following these meetings, Mr. Kruszewski was invited to attend the quarterly dinner of Thomas Weisel Partners’ board of directors.

On March 23, 2010, at a regularly scheduled meeting of the Thomas Weisel Partners board of directors, management updated the Thomas Weisel Partners’ board on discussions with Stifel. Sullivan & Cromwell LLP, Thomas Weisel Partners outside counsel, discussed with the board of directors the legal standards applicable to the board’s evaluation of Stifel’s proposal and its actions in this context. Mr. Kruszewski was then invited to address the board and explain his view of the merits of the proposal. At that meeting, Mr. Kruszewski presented a range for a possible exchange ratio for a potential combination of the firms. Mr. Kruszewski answered questions from the Thomas Weisel Partners board. Thomas Weisel Partners’ board then met together with Sullivan & Cromwell LLP in executive sessions without management present to discuss the transaction. In executive session, the Board determined to authorize Thomas Weisel Partners management to move forward with discussions with Stifel in order to determine if an acceptable transaction could be reached and requested that Mr. Barger, along with Mr. Weisel oversee the discussions with Stifel based on the proposed exchange ratio range.

On April 1, 2010, Bryan Cave LLP, Stifel’s outside counsel, distributed to Thomas Weisel Partners and its counsel, a draft merger agreement. The parties discussed the draft merger agreement over the period from April 2 to 4 following which Sullivan & Cromwell distributed a revised merger agreement reflecting Thomas Weisel Partners’ proposed changes. Bryan Cave provided a legal due diligence request list on April 3, 2010. During the weeks of April 5 and April 12, the parties exchanged due diligence materials and participated in due diligence meetings and continued to discuss and exchange drafts of definitive agreements as well as other transaction documents.

On April 5, 2010, the Stifel board met in person, with a portion attending telephonically. Mr. Kruszewski formally informed the board of a potential transaction with Thomas Weisel Partners. Mr. Kruszewski provided detailed background about Thomas Weisel Partners, including its significant investment banking business, particularly focusing on growth companies and in industries and sectors on which Stifel did not significantly focus. Further, he noted that Thomas Weisel Partners’ equity research, particularly in the energy, healthcare and technology sectors would be a complement to the equity research, sales and trading business of Stifel. Mr. Kruszewski also noted that there was very little overlap in each of these businesses. Financial information was reviewed and discussed, with the perceived potential for significant cost savings and other non-compensation synergies if a transaction was to be completed. Mr. Kruszewski explained that additional business and legal due diligence and financial analysis needed to be completed. The Stifel board management requested that management continue with its due diligence analysis.

On April 6, 2010, Thomas Weisel Partners engaged Houlihan Lokey to act as a financial advisor to Thomas Weisel Partners in connection with the proposed transaction.

While discussions regarding a proposed transaction with Stifel were ongoing, over the course of March and April 2010, at various times Mr. Weisel discussed with members of the compensation committee of the Thomas Weisel Partners board the need for additional incentives for senior management and key Thomas Weisel Partners employees, including equity incentives and revisions to existing incentive programs, all of which were in Mr. Weisel’s view required independent of the completion of a transaction with Stifel. Specifically, Mr. Weisel

and members of the compensation committee of the Thomas Weisel Partners board, discussed the challenges Thomas Weisel Partners faced retaining employees in light of recent departures and the current competitive market for talent. Mr. Weisel and members of the Compensation Committee of the Thomas Weisel Partners board also noted the effectiveness of the granting of key performer awards during the summer of 2008 by Thomas Weisel Partners as well as the apparent success enjoyed by certain competitors of Thomas Weisel Partners who had recently restructured their outstanding equity awards recently. The Compensation Committee met on April 22, 2010, and approved and recommended to the board of directors the following compensation agreements: (1) awards of up to 3,180,000 restricted stock units to senior management and key Thomas Weisel Partners employees in exchange for an agreement to extend their required notice to terminate employment with Thomas Weisel Partners and (2) an amendment to the structure of outstanding awards that waived any condition relating to continued employment services so long as the award recipient refrained from certain competitive and solicitation activities, both of which were adopted by the board of directors on April 22, 2010. No aspect of those compensation agreements was conditioned on a proposed transaction with Stifel.

On each of April 1, 2010, April 8, 2010 and April 15, 2010, the Thomas Weisel Partners board met telephonically to receive an update as to the current state of negotiations from Messrs. Weisel and Barger. During the April 15, 2010 board call, Mr. Weisel indicated that Mr. Kruszewski had proposed an exchange ratio of 0.1364 for Stifel stock to be received by Thomas Weisel Partners stockholders.

On April 15, 2010, Mr. Kruszewski informed the Stifel board of directors that he would like to call a special meeting to discuss the possible transaction with Thomas Weisel Partners in more specific terms. On April 16, 2010, Mr. Kruszewski scheduled special meetings of the Stifel board for April 23 and 24, 2010 to discuss the potential transaction and to conduct its regular quarterly meeting. Mr. Kruszewski also spoke telephonically with several board members about the upcoming meetings and scheduling.

On April 22, 2010, the Thomas Weisel Partners board met to discuss the terms and conditions of the merger agreement and related documentation, drafts of which were provided to the Thomas Weisel Partners board in advance of the meeting. Representatives from Sullivan & Cromwell LLP and Mr. Mark Fisher, the General Counsel of Thomas Weisel Partners, presented summaries of the agreements as well as a discussion of open issues remaining with respect to the draft documents. At this meeting, representatives from Houlihan Lokey discussed their preliminary financial analyses with respect to Thomas Weisel Partners and the proposed transaction with the Thomas Weisel Partners board. The Thomas Weisel Partners board, with the assistance of management and Thomas Weisel Partners’ legal and financial advisors, discussed the risks of the combination compared to the risks of continuing operations on a standalone basis. During the course of such discussions, management and Thomas Weisel Partners’ legal and financial advisors responded to numerous questions from the Thomas Weisel Partners board. Management discussed some of the steps that would follow execution of the definitive agreements if the transaction were to be approved, including the steps required to finalize communications plans to investors, employees, clients, suppliers and other constituencies.

The Stifel board met on April 23 and 24, 2010 in St. Louis, Missouri. On April 23, 2010, Mr. Weisel was invited to address the board and explain his view of the transaction and the merits of the proposed combination. During the course of the meeting, Mr. Weisel answered numerous questions from the Stifel board.

On April 24, 2010, the Stifel board reconvened to formally consider the transaction, at which meeting members of Stifel’s senior management and its legal and financial advisors made various presentations about, and the Stifel board discussed, the potential merger. Representatives from Bryan Cave LLP reviewed the board’s fiduciary duties in connection with the consideration of the proposed transaction and presented summaries of the terms of the merger agreement and other agreements proposed to be entered into in connection with the transaction. Sandler O’Neill + Partners, L.P. rendered then delivered its oral opinion (subsequently confirmed in writing) that, as of April 24, 2010, the exchange ratio in the merger is fair to Stifel from a financial point of view.

The Thomas Weisel Partners board met again telephonically on April 25, 2010 to consider the transaction with the assistance of management and Thomas Weisel Partners’ legal and financial advisors. Management summarized the terms of the transaction, and indicated the changes to the definitive agreements from the drafts distributed and discussed at length at the meeting held on April 22, 2010. Houlihan Lokey reviewed its updated financial analyses with respect to Thomas Weisel Partners and the proposed transaction and, thereafter, at the request of the Thomas Weisel Partners board delivered its oral opinion (which was subsequently confirmed in writing by delivery of Houlihan Lokey’s written opinion dated the same date) to the effect that, as of April 25, 2010, the exchange ratio provided for in the proposed merger was fair to the holders of Shares from a financial point of view. Representatives from Sullivan & Cromwell LLP reviewed the board’s fiduciary duties in connection with the consideration of the proposed transaction, and presented summaries of the terms of the merger agreement and other agreements proposed to be entered into in connection with the transaction. At the meeting, the Thomas Weisel Partners board also considered the fact that Thomas Weisel Partners’ senior management regularly communicated with public and private investment banking firms regarding potential business combination transactions, none of which led to any substantive discussions or was as attractive to Thomas Weisel Partners as a potential transaction with Stifel. In light of this, the Thomas Weisel Partners board determined that the proposed transaction with Stifel, together with the flexibility provided by the non-solicitation provisions in the merger agreement, would enable the board to exercise its fiduciary obligations.

After discussion, the Thomas Weisel Partners board unanimously (a) determined that the merger agreement and all related documents and exhibits thereto, in each case substantially in the form presented to the Thomas Weisel Partners board, and the merger are in the best interests of Thomas Weisel Partners and its stockholders, and (b) approved and declared advisable the merger agreement and the merger and the other transactions contemplated by the merger agreement and determined that the merger agreement and the transactions contemplated by the merger agreement, including the merger, are fair to, and in the best interests of, Thomas Weisel Partners and its stockholders, and (c) recommended the approval by Thomas Weisel Partners stockholders of the merger pursuant to the terms of the merger agreement.

Mr. Kruszewski traveled to San Francisco on April 25, 2010 to execute the merger agreement and for the purpose of preparing to announce the transaction the following morning from San Francisco. Prior to executing the merger agreement, the Stifel board met telephonically on April 25, 2010. Following a discussion, Stifel’s board of directors approved the merger agreement and the transactions contemplated by the merger agreement in substantially the form presented to the board on April 24, 2010.

Following the respective board meetings of Thomas Weisel Partners and Stifel, the parties executed the merger agreement.

On April 26, 2010, before the commencement of trading in the shares of Stifel and of Thomas Weisel Partners, both firms issued a joint press release announcing the execution of the merger agreement and the transaction.

Thomas Weisel Partners’ Reasons for the Merger

The board of directors, at the meeting described above on April 25, 2010, unanimously (i) determined that the merger agreement and the merger are fair to and in the best interests of Thomas Weisel Partners and its stockholders, (ii) approved, adopted and declared advisable the merger agreement, the merger and the other transactions contemplated by the merger agreement and authorized the execution and delivery of the merger agreement and (iii) resolved to recommend that the Thomas Weisel Partners stockholders approve and adopt the merger agreement and approve the merger and directed that such matter be submitted for consideration of the Thomas Weisel Partners stockholders at the Annual Meeting.

In reaching its decision to approve, adopt and declare advisable the merger agreement, the merger, and the other transactions contemplated by the merger agreement and to recommend that the Thomas Weisel Partners stockholders approve and adopt the merger agreement and approve the merger, the Thomas Weisel Partners

board of directors consulted with Thomas Weisel Partners’ senior management team, as well as Thomas Weisel Partners’ internal and outside legal and financial advisors, and considered a number of factors, including the following material factors that the Thomas Weisel Partners board of directors viewed as supporting its decision to approve and declare advisable the merger agreement, the merger and the other transactions contemplated by the merger agreement and to unanimously recommend that the Thomas Weisel Partners stockholders approve and adopt the merger agreement and approve the merger:

•

the financial analysis reviewed and discussed with the board of directors of Thomas Weisel Partners by representatives of Houlihan Lokey, as well as the oral opinion of Houlihan Lokey to the board of directors on April 25, 2010 (which was subsequently confirmed in writing by delivery of Houlihan Lokey’s written opinion dated the same date) with respect to the fairness to holders of Shares from a financial point of view of the exchange ratio provided for in the proposed merger;

•

Thomas Weisel Partners’ and Stifel’s financial performance and condition, results of operations, management, business quality, prospects, competitive position and businesses as separate entities and on a combined basis;

•

the anticipated financial performance and condition, results of operations management, business quality, prospects, competitive position and businesses of Stifel and Thomas Weisel Partners after giving effect to the merger;

•

the strategic nature of the merger and increased opportunity for growth;

•

the risks faced by Thomas Weisel Partners as a stand-alone company, including challenges in retaining key employees and clients and limitations as to retaining volumes and margins in the brokerage and asset management businesses with a smaller capital base than some competitors;

•

industry trends;

•

current financial market conditions and historical market prices, volatility and trading information with respect to Thomas Weisel Partners common stock and Stifel common stock;

•

the intrinsic value and historical market prices of Thomas Weisel Partners common stock and the fact that the exchange ratio (based on Stifel’s trading price at the close of business of April 23, 2010, the last trading day before the Thomas Weisel Partners board of directors approved the merger agreement) to be paid by Stifel in the merger represented a premium of:

•

74% over the closing price of Thomas Weisel Partners common stock of $4.36 per share at the close of business on April 23, 2010, the last trading day prior to the announcement of the proposed merger; and

•

83% over the average closing price of Thomas Weisel Partners common stock of $4.16 per share for the ten trading days immediately prior to April 23, 2010.

•

the Thomas Weisel Partners directors’ belief that the consideration to be paid by Stifel in the merger represented the highest price per share that could be negotiated with Stifel;

•

the financial and non-financial terms and conditions of the merger agreement, including:

•

the merger consideration; and

•

the parties’ representations, warranties and covenants and closing conditions.

•

the opportunity for Thomas Weisel Partners stockholders to participate in a larger company with a more liquid market for its stock and a more stable trading price historically and, as stockholders of the combined company, to participate in any increases in the value of its business following the merger;

•

the fact that the exchange ratio would enable Thomas Weisel Partners stockholders after the merger to own approximately 12.6% of the outstanding common stock of the combined company (including Stifel common stock issuable in respect of any exchangeable shares, but not including, in either case, any stock issuable in respect of restricted stock units outstanding after the merger); and

•

the results of due diligence investigations by management with the assistance of Thomas Weisel Partners’ legal and other advisors.

The Thomas Weisel Partners board of directors also considered potentially negative risks of the transaction, including:

•

the risk that despite the efforts of Thomas Weisel Partners and Stifel, key Thomas Weisel Partners personnel might not remain employed by Thomas Weisel Partners or, following the closing, the combined company;

•

the risk that potential benefits sought in the transaction may not be achieved in the expected timeframe or at all;

•

risks associated with Stifel’s business;

•

the possibility that the merger might not receive timely regulatory clearances from the appropriate government agencies or self-regulatory organizations;

•

the risk that the satisfaction of the other conditions to closing the merger might not be accomplished within the expected timeframe or at all;

•

the possibility that the merger might not be consummated and the potential adverse effects of the public announcement of the merger on:

•

Thomas Weisel Partners’ operating results;

•

Thomas Weisel Partners’ ability to attract and retain key employees; and

•

Thomas Weisel Partners’ overall competitive position;

•

the absence of any right of Thomas Weisel Partners to terminate the merger agreement if the value of Stifel common stock falls below any particular level prior to the merger or because of changes in the operating and financial performance of either company that do not amount to a material adverse effect, as defined in the merger agreement; and

•

that the consummation of the merger will preclude Thomas Weisel Partners stockholders from participating directly in any future growth of Thomas Weisel Partners were it to remain an independent public company.

The foregoing discussion of the factors considered by the Thomas Weisel Partners board of directors is not intended to be exhaustive, but rather includes the material factors considered by the Thomas Weisel Partners board of directors. In reaching its decision to approve and declare advisable the merger agreement, the merger and the other transactions contemplated by the merger agreement and to unanimously recommend that the Thomas Weisel Partners stockholders approve and adopt the merger agreement and approve the merger, the Thomas Weisel Partners board of directors did not quantify or assign any relative weights to the factors considered and individual directors may have given different weights to different factors. After taking into consideration all of the information and factors described above, members of the Thomas Weisel Partners board of directors at its April 25, 2010 meeting unanimously concluded that the merger and the merger agreement are advisable, and are fair to, and in the best interests of, Thomas Weisel Partners and its stockholders and that Thomas Weisel Partners should proceed with the merger.

Recommendation of the Thomas Weisel Partners Board of Directors

The Thomas Weisel Partners board of directors believes that the merger and the merger agreement are advisable, and are fair to, and in the best interests of, Thomas Weisel Partners and its stockholders and recommends that Thomas Weisel Partners stockholders vote FOR the proposal to approve and adopt the merger agreement and approve the merger.

Opinion of Thomas Weisel Partners’ Financial Advisor

On April 25, 2010, Houlihan Lokey rendered its oral opinion to the board of directors of Thomas Weisel Partners (which was subsequently confirmed in writing by delivery of Houlihan Lokey’s written opinion dated the same date) to the effect that, as of April 25, 2010, the exchange ratio provided for in the proposed merger was fair to the holders of Shares from a financial point of view.

Houlihan Lokey’s opinion was directed to the board of directors of Thomas Weisel Partners and only addressed the fairness to the holders of Shares, from a financial point of view, of the exchange ratio provided for in the proposed merger, and did not address any other aspect or implication of the proposed merger. The summary of Houlihan Lokey’s opinion in this proxy statement is qualified in its entirety by reference to the full text of its written opinion, which is included as Annex B to this proxy statement and sets forth the procedures followed, assumptions made, qualifications and limitations on the review undertaken and other matters considered by Houlihan Lokey in preparing its opinion. However, neither Houlihan Lokey’s written opinion nor the summary of its opinion and the related analyses set forth in this proxy statement are intended to be, and do not constitute advice or a recommendation to any holder of Thomas Weisel Partners common stock and any holder of exchangeable shares as to how such stockholder should act or vote with respect to any matter relating to the proposed merger.

In arriving at its opinion, Houlihan Lokey:

reviewed a draft, dated April 25, 2010, of the merger agreement;

reviewed certain publicly available business and financial information relating to Thomas Weisel Partners and Stifel that Houlihan Lokey deemed to be relevant (and adjustments thereto), including certain publicly available research analyst estimates with respect to the future financial performance and condition including, without limitation, the net tangible book value and net revenue, of Thomas Weisel Partners and Stifel (the “Street Estimates”);

reviewed certain information relating to the historical, current and future operations, financial condition and prospects of Thomas Weisel Partners and Stifel made available to Houlihan Lokey by Thomas Weisel Partners and Stifel, including financial projections (and adjustments thereto) prepared by the management of Thomas Weisel Partners relating to Thomas Weisel Partners for the fiscal year ending December 31, 2010 (the “Company Projections”);

spoke with certain members of the managements of Thomas Weisel Partners and Stifel and certain of their respective representatives and advisors regarding the businesses, operations, financial condition and prospects of Thomas Weisel Partners and Stifel, respectively, the proposed merger and related matters;

compared the financial and operating performance of Thomas Weisel Partners and Stifel with that of other companies with publicly traded securities that Houlihan Lokey deemed to be relevant;

reviewed the current and historical market prices and trading volume for certain of Thomas Weisel Partners’ and Stifel’s publicly traded securities, and the historical market prices and certain financial data of the publicly traded securities of certain other companies that Houlihan Lokey deemed to be relevant;

compared the relative contributions of Thomas Weisel Partners and Stifel to certain financial statistics of the combined company on a pro forma basis; and

conducted such other financial studies, analyses and inquiries and considered such other information and factors as Houlihan Lokey deemed appropriate.

Houlihan Lokey relied upon and assumed, without independent verification, the accuracy and completeness of all data, material and other information furnished, or otherwise made available, to it, discussed with or reviewed by it, or publicly available, and did not assume any responsibility with respect to such data, material

and other information. In addition, management of Thomas Weisel Partners advised Houlihan Lokey, and Houlihan Lokey assumed, that the Company Projections reviewed by Houlihan Lokey had been reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of such management as to the future financial results and condition of Thomas Weisel Partners for the fiscal year ending December 31, 2010, and Houlihan Lokey expressed no opinion with respect to such projections or the assumptions on which they were based. As Thomas Weisel Partners was aware, Houlihan Lokey was not provided by Thomas Weisel Partners or Stifel with any projections with respect to the future operations, financial condition and prospects of Thomas Weisel Partners or Stifel other than the Company Projections and, at Thomas Weisel Partners’ instruction, Houlihan Lokey used and relied upon the Street Estimates with respect to Thomas Weisel Partners and Stifel referred to above, which Houlihan Lokey understood were a reasonable basis on which to evaluate the future financial performance of Thomas Weisel Partners and Stifel and were appropriate for such purposes. Houlihan Lokey did not assume any responsibility for the accuracy, validity or completeness of the Street Estimates or express any opinion with respect to such estimates or the assumptions on which they were based. Houlihan Lokey relied upon and assumed, without independent verification, that there had been no change in the business, assets, liabilities, financial condition, results of operations, cash flows or prospects of Thomas Weisel Partners or Stifel since the date of the most recent financial statements provided to Houlihan Lokey that would be material to its analyses or its opinion, and that there was no information or any facts that would make any of the information reviewed by Houlihan Lokey incomplete or misleading.

Houlihan Lokey relied upon and assumed, without independent verification, that, to the extent material to its analyses and its opinion (a) the representations and warranties of all parties to the merger agreement and all other related documents and instruments that are referred to therein were true and correct, (b) each party to the merger agreement and such other related documents and instruments would fully and timely perform all of the covenants and agreements required to be performed by such party, (c) all conditions to the consummation of the proposed merger would be satisfied without waiver thereof, and (d) the proposed merger would be consummated in a timely manner in accordance with the terms described in the merger agreement and such other related documents and instruments, without any amendments, modifications or waiver thereto. Houlihan Lokey also assumed, with the consent of the board of directors of Thomas Weisel Partners, that the proposed merger would be treated as a tax-free transaction. Houlihan Lokey also relied upon and assumed, without independent verification, that (i) the proposed merger would be consummated in a manner that complies in all respects with all applicable federal and state statutes, rules and regulations, and (ii) all governmental, regulatory, and other consents and approvals necessary for the consummation of the proposed merger would be obtained and that no delay, limitations, restrictions or conditions would be imposed or amendments, modifications or waivers made that would result in the disposition of any assets of Thomas Weisel Partners or Stifel, or otherwise have an effect on Thomas Weisel Partners or Stifel or any expected benefits of the proposed merger that would be material to its analyses or its opinion. In addition, Houlihan Lokey relied upon and assumed, without independent verification, that the final form of the merger agreement would not differ in any respect from the draft of the merger agreement identified above.

Furthermore, in connection with its opinion, Houlihan Lokey was not requested to make, and did not make, any physical inspection or independent appraisal or evaluation of any of the assets, properties or liabilities (fixed, contingent, derivative, off-balance-sheet or otherwise) of Thomas Weisel Partners, Stifel or any other party, nor was Houlihan Lokey provided with any such appraisal or evaluation. Houlihan Lokey did not estimate, and expressed no opinion regarding, the liquidation value of any entity or business. Houlihan Lokey did not undertake any independent analysis of any potential or actual litigation, regulatory action, possible unasserted claims or other contingent liabilities, to which Thomas Weisel Partners or Stifel was or may be a party or was or may be subject, or of any governmental investigation of any possible unasserted claims or other contingent liabilities to which Thomas Weisel Partners or Stifel was or may be a party or was or may be subject.

Houlihan Lokey was not requested to, and did not, (a) initiate or participate in any discussions or negotiations with, or solicit any indications of interest from, third parties with respect to the proposed merger, the securities, assets, businesses or operations of Thomas Weisel Partners or any other party, or any alternatives to

the proposed merger, (b) negotiate the terms of the proposed merger, or (c) advise the Board, Thomas Weisel Partners or any other party with respect to alternatives to the proposed merger. Houlihan Lokey’s opinion was necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to Houlihan Lokey as of, the date of its opinion. Houlihan Lokey did not undertake, and is under no obligation, to update, revise, reaffirm or withdraw its opinion, or otherwise comment on or consider events occurring or coming to Houlihan Lokey’s attention after the date of its opinion. Houlihan Lokey did not express any opinion as to what the value of Stifel common stock actually would be when issued pursuant to the proposed merger or the price or range of prices at which Thomas Weisel Partners common stock, the Thomas Weisel Partners exchangeable shares or Stifel common stock may be purchased or sold at any time. Houlihan Lokey assumed that Stifel common stock to be issued to holders of Thomas Weisel Partners common stock in the proposed merger would be listed on The New York Stock Exchange.

Houlihan Lokey’s opinion was furnished for the use and benefit of the board of directors of Thomas Weisel Partners (solely in its capacity as such) in connection with its consideration of the proposed merger and may not be used for any other purpose without Houlihan Lokey’s prior written consent. Houlihan Lokey’s opinion should not be construed as creating any fiduciary duty on Houlihan Lokey’s part to any party. Houlihan Lokey’s opinion was not intended to be, and does not constitute, a recommendation to the board of directors of Thomas Weisel Partners, Thomas Weisel Partners, any security holder or any other person as to how to act or vote with respect to any matter relating to the proposed merger.

Houlihan Lokey’s opinion only addressed whether, as of the date of the opinion, the exchange ratio provided for in the proposed merger was fair to the holders of Shares from a financial point of view and did not address any other aspect or implication of the proposed merger or any agreement, arrangement or understanding entered into in connection therewith or otherwise. In addition, Houlihan Lokey was not requested to opine as to, and its opinion does not express an opinion as to or otherwise address, among other things: (i) the underlying business decision of Thomas Weisel Partners, the holders of any Shares or any other securities of Thomas Weisel Partners or any other party to proceed with or effect the proposed merger, (ii) the terms of any arrangements, understandings, agreements or documents related to, or the form, structure or any other portion or aspect of, the proposed merger or otherwise (other than the exchange ratio to the extent expressly specified in its opinion), (iii) the fairness of any portion or aspect of the proposed merger to the holders of any class of securities, creditors or other constituencies of Thomas Weisel Partners, any of its subsidiaries or Stifel, or to any other party, except if and only to the extent expressly set forth in the last sentence of its opinion, (iv) the relative merits of the proposed merger as compared to any alternative business strategies that might exist for Thomas Weisel Partners, any of its subsidiaries or any other party or the effect of any other transaction in which Thomas Weisel Partners, any of its subsidiaries or any other party might engage, (v) the fairness of any portion or aspect of the proposed merger to any one class or group of Thomas Weisel Partners’, any of its subsidiaries’ or any other party’s security holders vis-à-vis any other class or group of Thomas Weisel Partners’, any of its subsidiaries’ or such other party’s security holders (including, without limitation, the allocation of any consideration amongst or within such classes or groups of security holders), (vi) whether or not Thomas Weisel Partners, any of its subsidiaries, Stifel, their respective security holders or any other party is receiving or paying reasonably equivalent value in the proposed merger, (vii) the solvency, creditworthiness or fair value of Thomas Weisel Partners, any of its subsidiaries or any other participant in the proposed merger, or any of their respective assets, under any applicable laws relating to bankruptcy, insolvency, fraudulent conveyance or similar matters, or (viii) the fairness, financial or otherwise, of the amount, nature or any other aspect of any compensation to or consideration payable to or received by any officers, directors or employees of any party to the proposed merger (in their capacity as such) or any class of such persons, relative to the exchange ratio or otherwise. Furthermore, no opinion, counsel or interpretation is intended in matters that require legal, regulatory, accounting, insurance, tax or other similar professional advice. It is assumed that such opinions, counsel or interpretations have been or would be obtained from the appropriate professional sources. Furthermore, Houlihan Lokey relied, with the consent of the board of directors, on the assessments by Thomas Weisel Partners, Stifel and their respective advisors, as to all legal, regulatory, accounting, insurance and tax matters with respect to Thomas Weisel Partners, Stifel and the proposed merger. The issuance of Houlihan Lokey’s opinion was approved by a committee authorized to approve such opinions.

In preparing its opinion to the board of directors of Thomas Weisel Partners, Houlihan Lokey performed a variety of analyses, including those described below. The summary of Houlihan Lokey’s valuation analyses described below is not a complete description of the analyses underlying Houlihan Lokey’s fairness opinion. The preparation of a fairness opinion is a complex process involving various quantitative and qualitative judgments and determinations with respect to the financial, comparative and other analytic methods employed and the adaptation and application of those methods to the unique facts and circumstances presented. As a consequence, neither Houlihan Lokey’s opinion nor the analyses underlying its opinion are readily susceptible to partial analysis or summary description. Houlihan Lokey arrived at its opinion based on the results of all analyses undertaken by it and assessed as a whole and did not draw, in isolation, conclusions from or with regard to any individual analysis, analytic method or factor. Accordingly, Houlihan Lokey believes that its analyses must be considered as a whole and that selecting portions of its analyses, analytic methods and factors, without considering all analyses and factors or the narrative description of the analyses, could create a misleading or incomplete view of the processes underlying its analyses and opinion.

In performing its analyses, Houlihan Lokey considered business, economic, industry and market conditions, financial and otherwise, and other matters as they existed on, and could be evaluated as of, the date of the written opinion. No company, transaction or business used in Houlihan Lokey’s analyses for comparative purposes is identical to Thomas Weisel Partners, Stifel or the proposed merger. While the results of each analysis were taken into account in reaching its overall conclusion with respect to fairness, Houlihan Lokey did not make separate or quantifiable judgments regarding individual analyses. The implied valuation reference ranges indicated by Houlihan Lokey’s analyses are illustrative and not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those suggested by the analyses. In addition, any analyses relating to the value of assets, businesses or securities do not purport to be appraisals or to reflect the prices at which businesses or securities actually may be sold, which may depend on a variety of factors, many of which are beyond our control and the control of Houlihan Lokey. Much of the information used in, and accordingly the results of, Houlihan Lokey’s analyses are inherently subject to substantial uncertainty.

Houlihan Lokey’s opinion and analyses were provided to the board of directors of Thomas Weisel Partners in connection with its consideration of the proposed merger and Houlihan Lokey’s analyses were among many factors considered by the board of directors of Thomas Weisel Partners in evaluating the proposed merger. Neither Houlihan Lokey’s opinion nor its analyses were determinative of the exchange ratio or of the views of the board of directors of Thomas Weisel Partners with respect to the proposed merger.

The following is a summary of the material financial analyses performed in connection with the preparation of Houlihan Lokey’s opinion rendered to the board of directors of Thomas Weisel Partners on April 25, 2010. The analyses summarized below include information presented in tabular format. The tables alone do not constitute a complete description of the analyses. Considering the data in the tables below without considering the full narrative description of the analyses, as well as the methodologies underlying and the assumptions, qualifications and limitations affecting each analysis, could create a misleading or incomplete view of Houlihan Lokey’s analyses.

For purposes of its analyses, Houlihan Lokey reviewed a number of financial metrics including:

•

Net Tangible Book Value—generally the value as of a specified date of the relevant company’s assets minus the value of the company’s intangible assets and the value of its liabilities, in each case as reflected on the financial statements of the company as of such date.

•

Net Revenue—generally the total revenue of the relevant company for a specified time period minus the company’s interest expense for such time period.

Unless the context indicates otherwise, equity values used in the selected companies analysis described below were calculated using the closing price of the common stock of Thomas Weisel Partners, Stifel and the selected companies listed below as of April 23, 2010. Estimates of Net Tangible Book Value for Thomas Weisel Partners, Stifel and the selected companies listed below for the fiscal year ending December 31, 2010 were based

on publicly available research analyst estimates. 2009 Net Tangible Book Value and 2009 Net Revenue for Thomas Weisel Partners were based on information provided by management of Thomas Weisel Partners. 2009 Net Tangible Book Value and 2009 Net Revenue for Stifel and the selected companies listed below were based on publicly available information for Stifel and the selected companies listed below.

Selected Companies Analysis

Houlihan Lokey calculated certain multiples of market value of equity for the selected companies in the investment banking and financial services industry deemed to be similar to Thomas Weisel Partners or Stifel, as the case may be, in one or more respects which included nature of business, size, diversification, financial performance and geographic concentration.

The calculated multiples included:

As a result, a significantly larger or smaller company with substantially similar lines of businesses and business focus may have been included while a similarly sized company with less similar lines of business and greater diversification may have been excluded. Houlihan Lokey identified a sufficient number of companies for purposes of its analysis but may not have included all companies that might be deemed comparable to Thomas Weisel Partners or Stifel.

Other Matters

Thomas Weisel Partners engaged Houlihan Lokey pursuant to a letter agreement dated as of April 6, 2010 to act as the board of directors’ financial advisor in connection with the proposed merger. Thomas Weisel Partners selected Houlihan Lokey based on Houlihan Lokey’s experience and reputation and knowledge of Thomas Weisel Partners and its industry. Houlihan Lokey is regularly engaged to render financial opinions in connection with mergers and acquisitions, financial restructurings, tax matters, ESOP and ERISA matters, corporate planning, and for other purposes. Houlihan Lokey will receive a fee for rendering certain financial advice to Thomas Weisel Partners with respect to the proposed merger including its opinion with respect to the fairness to the holders of Thomas Weisel Partners common stock and the exchangeable shares from a financial point of view of the exchange ratio provided for in the proposed merger. No portion of such fees is contingent upon the successful completion of the proposed merger. Thomas Weisel Partners has also agreed to reimburse certain of Houlihan Lokey’s expenses and to indemnify Houlihan Lokey and certain related parties for certain potential liabilities arising out of its engagement.

Houlihan Lokey and certain of its affiliates have in the past provided investment banking, financial advisory and other financial services to Thomas Weisel Partners, Stifel and/or certain of their respective affiliates, for which Houlihan Lokey and such affiliates have received compensation. Houlihan Lokey and certain of its affiliates may provide investment banking, financial advisory and other financial services to Thomas Weisel Partners, Stifel, other participants in the proposed merger and/or certain of their respective affiliates in the future, for which Houlihan Lokey and such affiliates may receive compensation. In addition, Houlihan Lokey and certain of its affiliates and certain of our and their respective employees may have committed to invest in private equity or other investment funds managed or advised by Thomas Weisel Partners, Stifel, other participants in the proposed merger and/or certain of their respective affiliates, and in portfolio companies of such funds, and may have co-invested with Thomas Weisel Partners, Stifel, other participants in the proposed merger and/or certain of their respective affiliates, and may do so in the future. Furthermore, in connection with bankruptcies, restructurings, and similar matters, Houlihan Lokey and certain of its affiliates may have in the past acted, may currently be acting and may in the future act as financial advisor to debtors, creditors, equity holders, trustees and other interested parties (including, without limitation, formal and informal committees or groups of creditors) that may have included or represented and may include or represent, directly or indirectly, or may have been adverse to, Thomas Weisel Partners, Stifel, other participants in the proposed merger and/or certain of their respective affiliates, for which advice and services Houlihan Lokey and such affiliates have received and may receive compensation.

In the ordinary course of business, certain of Houlihan Lokey’s affiliates, as well as investment funds in which they may have financial interests, may acquire, hold or sell, long or short positions, or trade or otherwise effect transactions, in debt, equity, and other securities and financial instruments (including loans and other obligations) of, or investments in, Thomas Weisel Partners, Stifel, or any other party that may be involved in the proposed merger and their respective affiliates or any currency or commodity that may be involved in the proposed merger.

Stifel’s Reasons for the Merger

Numerous factors were taken into consideration by Stifel in entering into the merger agreement, including, without limitation, the following:

•

the acceleration of Stifel’s ongoing investment banking growth, especially in the Technology, Healthcare, and Natural Resources industry coverage groups;

•

the firms’ highly complementary investment banking and research platforms, where Stifel believes there is relatively little overlap, including less than 10% overlap in research coverage;

•

the opportunity to benefit from a cyclical recovery in Thomas Weisel Partners’ core industry sectors of Technology, Healthcare and Natural Resources, where Thomas Weisel Partners is poised to benefit from improvement in the venture-backed IPO market, broader capital markets opportunities and merger and acquisition advisory opportunities;

•

the enhancement of Stifel’s mergers and acquisitions advisory services and lead managed equity underwriting credentials;

•

the strengthening of Stifel’s profile in the venture capital community, where Thomas Weisel Partners maintains key relationships;

•

diversify the revenue stream and balance the revenue contribution between Stifel’s Global Wealth Management and its Institutional Group segments;

•

the creation of the largest U.S. equity research platform, as measured by companies under coverage, and the largest provider of small cap equity research coverage in the United States;

•

the expansion of Stifel’s institutional equity business, both domestically and internationally, and its Global Wealth Management segment by adding the complementary resources of Thomas Weisel Partners;

•

the benefits from operating cost efficiencies, which the companies believe will allow them to enhance profitability; and

•

expand Stifel’s west coast market presence in the U.S. and Stifel’s international capabilities via Thomas Weisel Partners’ Canadian operations.

In reaching its decision to approve and enter into the merger agreement, the Stifel board did not view any single factor as determinative, and did not find it necessary or practicable to assign any relative or specific weights to the various factors considered. Furthermore, individual directors may have given differing weights to the various factors. The Stifel board of directors believed each of the factors listed above supported the decision to adopt the merger agreement.

The Stifel board of directors also considered various risks and challenges inherent in the combination with Thomas Weisel Partners, including the following:

•

the need to retain key personnel for the combined company;

•

the physically diverse and distant locations of the two companies;

•

the extent to which Stifel could be required to change the way in which research professionals interact with investment banking professionals to conform to existing Thomas Weisel Partners’ policies and procedures as result of its 2004 Global Research Analyst Settlement with the SEC;

•

the distraction of management with respect to the integration of the two companies;

•

the risk that anticipated cost savings and synergies might not be achieved as expected or at all;

•

the effect on each of the companies’ existing client relationships and the success of the combined company in entering into new client relationships; and

•

the fact that the financial services industry is subject to periodic market cycle risks.

However, the Stifel board of directors determined that the foregoing risks were outweighed by the potential benefits of the merger summarized above, including the opportunity for Stifel’s stockholders to share in the benefits of the combined company’s long-term prospects.

Interests of Certain Persons in the Merger

In considering the recommendations of Thomas Weisel Partners’ board of directors with respect to the merger, you should be aware that certain executive officers and members of the board of directors of Thomas Weisel Partners have agreements or arrangements that provide them with interests in the merger that may be different from, or in addition to, the interests of the other stockholders of Thomas Weisel Partners. Thomas Weisel Partners’ board of directors was aware of these agreements during its deliberations of the merits of the merger and in determining to recommend to Thomas Weisel Partners stockholders that they vote for the proposal to approve and adopt the merger agreement and the merger.

Common Stock

As of April 30, 2010, the record date of the special meeting, the executive officers and directors of Thomas Weisel Partners and their affiliates beneficially owned an aggregate 5,452,552 shares, or 16.6%, of outstanding Thomas Weisel Partners common stock (including shares issuable upon exchange of outstanding exchangeable shares), which will be treated in the merger in the same manner as shares of Thomas Weisel Partners common stock held by other stockholders of Thomas Weisel Partners.

Appointment of Directors and Executive Officers

Stifel has announced that Thomas W. Weisel will become the Co-Chairman of the board of directors of Stifel with Mr. Kruszewski. Mr. Kruszewski will remain the President and CEO of Stifel. Stifel and Thomas Weisel Partners also expect that upon completion of the merger, Stifel will appoint to the Stifel board of directors up to three additional members of the Thomas Weisel Partners board of directors who were members of the Thomas Weisel Partners board of directors as of the date of the merger agreement. Such individuals have not yet been identified. See “Board of Directors and Executive Officers of Stifel Following the Merger” below for more information. Stifel currently anticipates that the senior management of Thomas Weisel Partners, including several of its executive officers, will be executive officers and/or key employees of Stifel following the merger.

Thomas Weisel Partners’ Stock Options and Other Equity-Based Awards

On April 22, 2010, the board of directors of Thomas Weisel Partners upon the recommendation of its Compensation Committee authorized Thomas Weisel Partners: (1) to enter into agreements to cancel performance awards previously granted on August 6, 2008 to each of Mr. Thomas Carbeau, Head of Institutional Sales, Mr. Keith Gay, Head of Research, Mr. William McLeod, Co-Head of Investment Banking, Mr. Bradford Raymond, Co-Head of Investment Banking, Mr. Anthony Stais, Head of Trading, and Mr. Shaugn Stanley, Chief Administrative Officer, and (2) to replace those awards with new restricted stock unit awards based on time vesting over three years and with no performance condition. The grant date for the new restricted stock unit awards was April 25, 2010.

On April 22, 2010, the board of directors of Thomas Weisel Partners upon the recommendation of its Compensation Committee approved the grant of up to 3,180,000 additional restricted stock units to certain employees, including executive officers of Thomas Weisel Partners. In order to have the desired effect of retaining and motivating employees, these new restricted stock units would be subject to a three-year cliff vesting provision and would be granted only to those employees who agreed to extend their required notice to terminate employment with Thomas Weisel Partners through the later of 90 days following notice or June 30, 2011. The grant date for the new restricted stock unit awards was April 23, 2010.

On April 22, the board of directors of Thomas Weisel Partners approved the waiver of certain requirements for vesting of restricted stock units held by its current employees, including its executive officers (other than those employees who had given notice of an intention to terminate their employment prior to April 23, 2010). The waiver was effective as of April 23, 2010 and eliminated any continued employment service requirements for vesting under Section 11(d)(i) of Thomas Weisel Partners’ Third Amended and Restated Equity Incentive Plan, if and so long as (but only for so long as) the holder of such restricted stock unit refrains from engaging in a competitive activity or a soliciting activity prior to the relevant vesting date or dates of such awards. As a result of the waiver of any continued employment service requirements for vesting, Thomas Weisel Partners immediately recognized the remaining non-cash share based compensation expense for these grants of restricted stock unit awards that were subject only to the passage of time. Thomas Weisel Partners estimated the non-cash compensation share based compensation charge to be approximately $55 to $60 million.

No aspect of the compensation arrangements described above was conditioned upon a proposed transaction with Stifel.

Stifel Equity Awards and Incentive Plans

Subsequent to the effective time of the merger, Stifel intends to grant equity awards to certain Thomas Weisel Partners employees, particularly those in the sales and trading areas, as well as approximately 35,000 Stifel restricted stock unit awards to Thomas W. Weisel. In addition, the compensation committee of Stifel’s board of directors is considering aligning its equity plans with the Thomas Weisel Partners’ equity plans, whereby it would eliminate any continued employment service requirements for vesting if and so long as (but only for so long as) the holder of such restricted stock unit refrains from engaging in a competitive activity or a soliciting activity prior to the relevant vesting date or dates of such awards. Stifel believes that this action would result in the acceleration of the non-cash compensation expense associated with these equity awards resulting in an after tax charge of approximately $85-96 million with a corresponding increase to additional paid in capital. These modifications, if adopted by Stifel, would apply to future equity awards granted by Stifel after the merger to former employees of Thomas Weisel Partners, including the awards for Mr. Weisel described above.

Potential Payments Upon Termination

Thomas Weisel Partners has entered into an employment agreement with Thomas W. Weisel which provides Mr. Weisel with a one-time, lump-sum cash severance payment, as well as other benefits, in the event his employment is involuntarily terminated without cause or he resigns for good reason. Thomas Weisel Partners also entered into an employment agreement with Lionel Conacher, which provides for certain payments and benefits in connection with any termination of Mr. Conacher’s employment. Thomas Weisel Partners gave notice of termination to Mr. Conacher on April 22, 2010 and as a result Mr. Conacher will become entitled to a severance payment of approximately $5.2 million at the effective time of his termination. For a discussion of the potential payments upon termination, see “Information Concerning Thomas Weisel Partners Board and Management—Option Exercises and Stock Vested—Potential Payments Upon Termination or Change-in-Control” on page 127.

Employee Benefits

Voting Agreements

In connection with the merger agreement, Stifel entered into stockholder voting agreements with each of Thomas Weisel, Chairman and Chief Executive Officer, Lionel Conacher, former President and Chief Operating

Officer, Thomas Carbeau, Head of Institutional Sales, Richard Gay, Head of Research, William McLeod, Co-Head of Investment Banking, Brad Raymond, Co-Head of Investment Banking, Paul Slivon, Chairman of Wealth Management, Anthony Stais, Head of Trading, and Shaugn Stanley, Chief Administrative Officer, who are all Thomas Weisel Partners executives. For a discussion of these stockholders agreements, see “Other Agreements Relating to the Merger—The Voting Agreements” on page 103.

Indemnification and Insurance

Pursuant to the merger agreement, Stifel has agreed that, after the effective time of the merger, it will provide certain indemnification and liability insurance benefits to present and former directors and officers of Thomas Weisel Partners. See “The Merger Agreement—Other Covenants and Agreements—Indemnification and Insurance” on page 99.

Board of Directors and Executive Officers of Stifel Following the Merger

Stifel has announced that upon the completion of the merger, Ronald J. Kruszewski and Thomas W. Weisel will be Co-Chairmen of the Stifel board of directors, and Mr. Kruszewski will remain President and CEO of Stifel. Stifel and Thomas Weisel Partners also expect that upon completion of the merger, Stifel will appoint to the Stifel board of directors up to three additional members of the Thomas Weisel Partners board of directors who were members of the Thomas Weisel Partners board of directors as of the date of the merger agreement. Such individuals have not yet been identified.

Stifel currently anticipates that the senior management of Thomas Weisel Partners, including several of its executive officers, will be executive officers and/or key employees of Stifel following the merger.

No Stifel Stockholder Approval

Stifel’s Dividend Policy

Stifel has not declared or paid a cash dividend on its common stock since 2002. Stifel currently intends to retain any future earnings to fund the growth and development of its businesses and does not anticipate paying any cash dividends in the foreseeable future.

Ownership of Stifel Following the Merger

The foregoing does not take into consideration any restricted stock units of either Stifel or Thomas Weisel Partners. As of April 30, 2010, Thomas Weisel Partners had 13,635,258 restricted stock units outstanding which will convert into the right to receive 1,859,849 shares of Stifel common stock upon consummation of the merger. As of April 30, 2010, Stifel had 7,359,656 restricted stock units outstanding.

Manner and Procedure for Exchanging Shares of Thomas Weisel Partners Stock

The conversion of Thomas Weisel Partners common stock into the right to receive the merger consideration will occur automatically at the effective time of the merger. The conversion of the one share of Thomas Weisel Partners special voting preferred stock into the one share of Stifel special voting preferred stock will occur automatically at the effective time of the merger.

Prior to the completion of the merger, Stifel will select a commercial bank or trust company reasonably acceptable to Thomas Weisel Partners to act as the exchange agent, for the purpose of exchanging certificates or book entry shares representing Thomas Weisel Partners shares for the merger consideration and to perform other duties as explained in the merger agreement. If you hold your own shares of Thomas Weisel Partners common stock in certificated form, promptly after the effective time of the merger, and in no event later than the third business day following the effective time of the merger, the exchange agent will mail you a letter of transmittal which will contain instructions on how to surrender your shares of Thomas Weisel Partners common stock in exchange for the merger consideration. The exchange agent will pay you the merger consideration to which you are entitled after you have provided to the exchange agent your signed letter of transmittal, surrendered your stock and provided any other items specified by the letter of transmittal. You should not submit your Thomas Weisel Partners stock certificates for exchange until you receive the transmittal instructions and a form of letter of transmittal from the exchange agent. Holders of book-entry shares will automatically receive the merger consideration and will not be required to deliver a certificate or an executed letter of transmittal to the exchange agent.

In the event of a transfer of ownership of Thomas Weisel Partners common stock that is not registered in Thomas Weisel Partners’ transfer agent’s records, payment of the merger consideration as described above will be made to a person other than the person in whose name the certificate so surrendered is registered only if the certificate is properly endorsed or otherwise is in proper form for transfer, and the person requesting the exchange must pay any transfer or other taxes required by reason of the payment of the merger consideration to such other person.

Thomas Weisel Partners stockholders will not receive any fractional shares of Stifel common stock pursuant to the merger. Instead of any fractional shares, stockholders will be paid an amount in cash for such fraction of a share calculated by multiplying (A) the fractional share interest to which such holder (after taking into account all shares of Thomas Weisel Partners common stock surrendered by such holder) would otherwise be entitled by (B) the average closing sales prices for a share of Stifel common stock for each of the ten consecutive trading days ending with the second complete trading day prior to the effective time of the merger, as such prices are reported on the NYSE Transaction Reporting System. Additionally, six months after the effective time of the merger, the exchange agent will deliver to Stifel all cash and shares of Stifel common stock remaining in the exchange fund administered by the exchange agent that have not been distributed to holders of Thomas Weisel Partners shares. Thereafter, Thomas Weisel Partners stockholders must look only to Stifel, and Stifel will remain liable, for payment of the merger consideration on their shares of Thomas Weisel Partners common stock. Any portion of the exchange fund administered by the exchange agent remaining unclaimed by holders of shares of Thomas Weisel Partners common stock two years after the effective time of the merger (or immediately prior to such time as such amounts would otherwise escheat to or become property of any governmental authority) will, to the extent permitted by applicable law, become the property of the surviving company.

The holders of exchangeable shares will not receive any fractional shares of Stifel common stock upon an exchange of exchangeable shares. Instead of any fractional shares, holders of exchangeable shares will be paid, at the time of exchange, an amount in cash for such fraction of a share calculated by multiplying (A) the fractional share interest to which such holder of exchangeable shares (after taking into account all exchangeable shares exchanged by such holder at the time of exchange) would otherwise be entitled by (B) the average closing sales prices for a share of Stifel common stock for each of the ten consecutive trading days ending with the second complete trading day prior to the effective time of the merger, as such prices are reported on the NYSE Transaction Reporting System. For a more complete description of what holders of exchangeable shares will receive in the merger, see Annex C, entitled “Supplemental Information for the Holders of Exchangeable Shares.”

Accounting Treatment

In accordance with accounting principles generally accepted in the United States, Stifel will account for the merger using the acquisition method of accounting for business combinations. Under this method of accounting, Stifel will record the acquisition based on the fair value of the consideration given, which is the market value (based on the closing price of Stifel common stock on the closing date of the merger) of its common stock issued in connection with the merger. Stifel will allocate the purchase price to the net tangible and identifiable intangible assets acquired and liabilities assumed based on their respective fair values at the date of the completion of the merger. Any excess of the purchase price over those fair values will be recorded as goodwill.

Regulatory Approvals

Under the merger agreement, Thomas Weisel Partners and Stifel have both agreed to use their reasonable best efforts to apply for and obtain all regulatory approvals necessary or advisable in connection with the transactions contemplated by the merger agreement.

Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended

The HSR Act prohibits Stifel and Thomas Weisel Partners from completing the merger until Stifel and Thomas Weisel Partners have furnished certain information and materials to the Antitrust Division of the Department of Justice and the Federal Trade Commission and the required waiting period has expired or been terminated. Stifel and Thomas Weisel Partners intend to each file the required notification and report forms as soon as practicable after the date of this proxy statement/prospectus.

Additional Regulatory Approvals

Financial Industry Regulatory Authority

As a member of the Financial Industry Regulatory Authority, or FINRA, Thomas Weisel Partners LLC, a wholly-owned subsidiary of Thomas Weisel Partners, is required to file with FINRA an application for approval of the change of its ownership that will result from the transaction. Thomas Weisel Partners intends to submit an application to FINRA for approval of the change of control of Thomas Weisel Partners LLC as soon as practicable after the date of this proxy statement/prospectus.

Investment Industry Regulatory Organization of Canada

As a member of the Investment Industry Regulatory Organization of Canada, or IIROC (a self-regulatory organization for Canadian registered investment dealers), Thomas Weisel Partners Canada Inc., a wholly-owned subsidiary of Thomas Weisel Partners, is required to provide notice to IIROC and obtain approval from the Ontario District Council of IIROC for the various steps relating to the change of control of Thomas Weisel Partners Canada Inc. Thomas Weisel Partners intends to file a notice and application for approval with IIROC as soon as practicable after the date of this proxy statement/prospectus.

Canadian Securities Regulatory Authorities

As Thomas Weisel Partners Canada Inc. is registered in Canada in the category of Investment Dealer with each of the Ontario Securities Commission, the Autorité des marchés financiers (Québec), the British Columbia Securities Commission, the Alberta Securities Commission, the Manitoba Securities Commission, the Nova Scotia Securities Commission and the Saskatchewan Financial Services Commission, or altogether, the Canadian regulators, it is required to notify the Canadian regulators of the change of its ownership that will result from the merger. If, within 30 days of the receipt of the change of ownership notice, a Canadian regulator notifies Thomas Weisel Partners Canada Inc. that it objects to the acquisition, the acquisition must not occur until the Canadian regulator approves it. Thomas Weisel Partners intends to submit a notice of change of ownership of Thomas

Weisel Partners Canada Inc. to the Canadian regulators as soon as practicable after the date of this proxy statement/prospectus.

United Kingdom Financial Services Authority

The businesses that a subsidiary of Thomas Weisel Partners conducts in the United Kingdom are regulated by the Financial Services Authority, or the FSA. Accordingly, Stifel and Thomas Weisel Partners must obtain, and the transaction is conditioned upon receiving, the approval of the FSA. Thomas Weisel Partners and Stifel intend to submit an application to the FSA as soon as practicable after the date of this proxy statement/prospectus.

In addition to the regulatory approvals discussed above, notices or approvals also are required to be filed with or obtained from the Toronto Stock Exchange, the TSX Venture Exchange, the New York Stock Exchange and Chicago Stock Exchange, among others.

Merger Expenses, Fees and Costs

Except with respect to the filing fee for the registration statement of which this proxy statement/prospectus forms a part and certain filing fees under antitrust laws, all of which will be shared equally by Stifel and Thomas Weisel Partners, each of Stifel and Thomas Weisel Partners will be responsible for all expenses incurred by it in connection with the negotiation and completion of the transactions contemplated by the merger agreement.

Appraisal Rights

Holders of Thomas Weisel Partners common stock are not entitled to appraisal rights under the Delaware General Corporation Law in connection with the merger.

Under the Delaware General Corporation Law, if the stockholder of record of the one share of the Thomas Weisel Partners special voting preferred stock does not wish to receive the one Stifel special voting preferred share, then the stockholder of record of the share of Thomas Weisel Partners special voting preferred stock has the right to seek an appraisal of, and to be paid the fair value for, the share of Thomas Weisel Partners special voting preferred stock if the stockholder complies with the provisions of Section 262 of the Delaware General Corporation Law.

If the holder of the share of the Thomas Weisel Partners special voting preferred stock wishes to exercise appraisal rights, it must not cast any of the votes attached to the share of Thomas Weisel Partners special voting preferred stock in favor of the approval and adoption of the merger agreement and must deliver to Thomas Weisel Partners before the vote on the merger agreement at the Annual Meeting, a written demand for appraisal of the share of the Thomas Weisel Partners special voting preferred stock as set forth in more detail on Annex D to this proxy statement/prospectus. This written demand for appraisal is in addition to and separate from any proxy or vote abstaining from or against the approval and adoption of the merger agreement.

With respect to the one share of Thomas Weisel Partners special voting preferred stock, Thomas Weisel Partners believes that if the trustee exercises any of the votes attached to the Thomas Weisel Partners special voting preferred stock to vote in favor of the proposal to approve and adopt the merger agreement and approve the merger, then the trustee will not be entitled under Section 262 to an appraisal of the Thomas Weisel Partners special voting preferred stock or any interest therein. Accordingly, Thomas Weisel Partners believes that, if the trustee is instructed by at least one holder of exchangeable shares to cast at least one vote at the Annual Meeting in favor of the proposal to approve and adopt the merger agreement and approve the merger and the trustee complies with these instructions, the trustee will not be entitled to an appraisal of the one share of Thomas Weisel Partners special voting preferred stock or any interest therein under Section 262.

The foregoing discussion is not a complete statement of the law of appraisal rights and is qualified in its entirety by the summary and full text of Section 262 of the Delaware General Corporation Law, which is reprinted in its entirety as Annex D to this proxy statement/prospectus.

Restrictions on Sales of Shares by Certain Affiliates

The shares of Stifel common stock to be issued or reserved for issuance in connection with the merger will be freely transferable under the U.S. Securities Act of 1933, as amended, or the Securities Act, except for shares issued to any stockholder who may be deemed to be an “affiliate” of Stifel for purposes of Rule 144 under the Securities Act. Persons who may be deemed to be affiliates include individuals or entities that control, are controlled by, or under the common control with Stifel and may include the executive officers, directors and significant stockholders of Stifel.

Effect of the Merger on Outstanding Options and Equity Awards and Warrant

Stock Exchange Listing of Stifel Stock; Delisting/De-registration of Thomas Weisel Partners Stock

The shares of Stifel common stock to be issued in the merger will be listed on the NYSE. If the merger is completed, Thomas Weisel Partners common stock will no longer be registered under the Exchange Act or listed on the NASDAQ Global Market.

THE MERGER AGREEMENT

The following summary describes material provisions of the merger agreement. This summary does not purport to be complete and may not contain all of the information about the merger agreement that is important to you. This summary is subject to, and qualified in its entirety by reference to, the merger agreement, which is attached to this proxy statement/prospectus as Annex A and is incorporated by reference into this proxy statement/prospectus. You are urged to read the merger agreement carefully and in its entirety, as it is the legal document governing the merger.

The merger agreement summary below is included in this proxy statement/prospectus only to provide you with information regarding the terms and conditions of the merger agreement, and not to provide any other factual information regarding Thomas Weisel Partners, Stifel or their respective businesses. Accordingly, the representations and warranties and other provisions of the merger agreement should not be read alone, but instead should be read only in conjunction with the information provided elsewhere in this proxy statement/prospectus and in the documents incorporated by reference into this proxy statement/prospectus. See “Where You Can Find More Information” on page 153.

The representations, warranties and covenants contained in the merger agreement and described in this proxy statement/prospectus were made only for purposes of the merger agreement and as of specific dates and may be subject to more recent developments, were made solely for the benefit of the parties to the merger agreement and may be subject to limitations agreed upon by the contracting parties, including being qualified by reference to confidential disclosures, for the purposes of allocating risk between parties to the merger agreement instead of establishing these matters as facts, and may apply standards of materiality in a way that is different from what may be viewed as material by you or by other investors. Accordingly, these representations and warranties alone may not describe the actual state of affairs as of the date they were made or at any other time. The representations and warranties contained in the merger agreement do not survive the effective time of the merger. Investors should not rely on the representations, warranties and covenants or any description thereof as characterizations of the actual state of facts or condition of Thomas Weisel Partners, Stifel or Merger Sub or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the merger agreement, which subsequent information may or may not be fully reflected in public disclosures by Thomas Weisel Partners and Stifel.

The Merger

Each of the Thomas Weisel Partners board of directors and the Stifel board of directors has approved the merger agreement, which provides for the merger of Merger Sub with and into Thomas Weisel Partners upon the terms, and subject to the conditions, of the merger agreement. Thomas Weisel Partners will be the surviving corporation in the merger and, following the merger, will be a wholly-owned subsidiary of Stifel and will no longer be a publicly held corporation.

Closing

Under the terms of the merger agreement, the closing of the merger will occur no later than two business days following the satisfaction or waiver of the conditions to closing (other than conditions that, by their nature, cannot be satisfied until the closing of the merger, but subject to the satisfaction of, or to the extent permissible, waiver of those conditions). Notwithstanding the foregoing, either party may, at its option, if the closing would otherwise occur within ten days before the last business day of a calendar month, defer the closing to the final business day of such month.

Effective Time

At the closing of the merger, Thomas Weisel Partners will file a certificate of merger with the Secretary of State of Delaware. The merger will become effective when the certificate of merger is filed with the Secretary of State of the State of Delaware or at a later time as agreed to by Stifel and Thomas Weisel Partners and set forth in the certificate of merger.

Merger Consideration

Stifel will not issue any fractional shares of Stifel common stock in the merger. Instead, a Thomas Weisel Partners stockholder who otherwise would have received a fraction of a share of Stifel common stock will receive an amount in cash rather than a fractional share. This cash amount will be determined by multiplying the fraction of a share of Stifel common stock to which the holder would otherwise be entitled by the average closing sales prices for a share of Stifel common stock for the ten consecutive trading days ending two days prior to the effective time of the merger, as such prices are reported on the NYSE Composite Transactions Tape (as reported by The Wall Street Journal (Northeast edition), or, if not reported thereby, as reported by any other authoritative source).

Other than a possible adjustment under limited circumstances as described in the next paragraph below, the exchange ratio of 0.1364 of a share of Stifel common stock is fixed, and it will not change between now and the date of the merger, including as a result of a change in the trading price of Stifel common stock or Thomas Weisel Partners common stock or the operating and financial performance of either company. Therefore, the specific dollar value of the shares of Stifel common stock received by Thomas Weisel Partners stockholders in the merger will depend on the market value of Stifel common stock at the time the merger is completed.

The one share of Thomas Weisel Partners special voting preferred stock issued and outstanding immediately prior to the effective time of the merger will be converted into one share of a new series of Stifel special voting preferred stock having the same powers, designations, preferences and rights (to the fullest extent practicable) as the shares of the Thomas Weisel Partners special voting preferred stock (except that the issuer thereof will be Stifel rather than Thomas Weisel Partners and the voting rights described therein will apply to Stifel common stock rather than to Thomas Weisel Partners common stock).

Treatment of Thomas Weisel Partners Stock Options and Other Equity-Based Awards and Warrant

Thomas Weisel Partners common stock subject to such award multiplied by the exchange ratio. Following the effective time of the merger, each restricted stock unit will continue to be governed by the same terms and conditions, including any vesting requirements, as were applicable prior to the merger. At the effective time of the merger, all outstanding Thomas Weisel Partners stock options will be converted into the right to acquire a number of shares of Stifel common stock equal to the number of shares of Thomas Weisel Partners common stock subject to such award multiplied by the exchange ratio, and the exercise price of the award will equal the exercise price per share of Thomas Weisel Partners common stock applicable to such award divided by the exchange ratio. Following the effective time of the merger, each stock option will continue to be governed by the same terms and conditions, including any vesting requirements, as were applicable prior to the merger.

Treatment of Exchangeable Shares

Assuming that the holders of the exchangeable shares approve the Exchangeable Share Amendment, the exchangeable shares will not be converted into other securities as part of the merger. In that case, each exchangeable share will remain outstanding and become exchangeable for 0.1364 shares of Stifel common stock. In the event the Exchangeable Share Amendment is approved, at the effective time of the merger, the one outstanding share of Thomas Weisel Partners special voting preferred stock will be canceled and automatically converted into one share of Stifel special voting preferred stock. The one share of Stifel special voting preferred stock will entitle the holder to that number of votes equal to the number of shares of Stifel common stock issuable upon exchange of the exchangeable shares outstanding from time to time other than exchangeable shares held by Stifel or any person directly or indirectly controlled by or under common control of Stifel. Pursuant to the merger agreement, if the Exchangeable Share Amendment is not approved, Thomas Weisel Partners will take all actions necessary to (a) cause TWP Acquisition Company (Canada), Inc. to exercise its right to redeem all of the outstanding exchangeable shares or (b) acquire or cause TWP Holdings Company (Canada), ULC to acquire all of the outstanding exchangeable shares, and, as a result of the merger, holders of exchangeable shares would receive shares of Stifel common stock. For a further description of what holders of exchangeable shares will receive in the merger, see Annex C, entitled “Supplemental Information for the Holders of Exchangeable Shares.”

Conversion of Shares; Exchange of Certificates

The conversion of Thomas Weisel Partners common stock into the right to receive the merger consideration will occur automatically at the effective time of the merger. Assuming that the holders of the exchangeable shares approve the Exchangeable Share Amendment, the conversion of the one share of Thomas Weisel Partners special voting preferred stock into the one share of Stifel special voting preferred stock will occur automatically at the effective time of the merger.

Prior to the effective time of the merger, Stifel will select a commercial bank or trust company (subject to Thomas Weisel Partners’ approval not to be unreasonably withheld or delayed) to act as the exchange agent, for the purpose of exchanging certificates or uncertificated shares representing Thomas Weisel Partners shares for the merger consideration and perform other duties as explained in the merger agreement. Simultaneously with or prior to the effective time of the merger, Stifel will deposit or cause to be deposited with such exchange agent securities representing shares of Stifel common stock issuable and payable in exchange for outstanding Thomas Weisel Partners shares and, after the merger, any cash and dividends or other distribution with respect to the Stifel common stock to be issued or paid in lieu of fractional shares and for any dividends or distributions declared following the effective time of the merger.

Following the effective time of the merger, there will be no further transfers of shares of Thomas Weisel Partners stock. If you hold your shares of Thomas Weisel Partners common stock in certificated form, promptly after the effective time of the merger, and in no event later than the third business day following the effective

time of the merger, Stifel will send or will cause the exchange agent to send you a letter of transmittal which will contain instructions on how to surrender your shares of Thomas Weisel Partners common stock in exchange for the merger consideration. The exchange agent will pay you the merger consideration to which you are entitled after you have provided to the exchange agent your signed letter of transmittal, surrendered your shares of Thomas Weisel Partners stock and provided any other items specified by the letter of transmittal.

You should not submit your Thomas Weisel Partners stock certificates for exchange until you receive the transmittal instructions and a form of letter of transmittal from the exchange agent.

Holders of book-entry shares will automatically receive the merger consideration and will not be required to deliver a certificate or an executed letter of transmittal to the exchange agent. Except as described above, interest will not be paid or accrue in respect of the merger consideration. The merger consideration paid to you will be reduced by any applicable tax withholding. In the event of a transfer of ownership of Thomas Weisel Partners common stock that is not registered in Thomas Weisel Partners’ transfer agent’s records, payment of the merger consideration as described above will be made to a person other than the person in whose name the certificate so surrendered is registered only if the certificate is properly endorsed or otherwise is in proper form for transfer; and the person requesting the exchange must pay any transfer or other taxes required by reason of the payment of the merger consideration to such other person.

Six months after the effective time of the merger, the exchange agent will deliver to Stifel all cash and shares of Stifel common stock remaining in the exchange fund administered by the exchange agent that have not been distributed to holders of Thomas Weisel Partners shares. Thereafter, Thomas Weisel Partners stockholders must look only to Stifel, and Stifel will remain liable, for payment of the merger consideration on their shares of Thomas Weisel Partners stock. Any portion of the exchange fund administered by the exchange agent remaining unclaimed by holders of shares of Thomas Weisel Partners common stock two years after the effective time of the merger (or immediately prior to such time as such amounts would otherwise escheat to or become property of any governmental authority) will, to the extent permitted by applicable law, become the property of the Stifel free and clear of any claims or interest of any person previously entitled thereto.

Dividends and Distributions

Whenever a dividend or other distribution is declared by Stifel in respect of Stifel common stock, the record date for which is at or after the effective time of the merger, that declaration will include dividends or other distributions in respect of all shares of Stifel common stock issuable pursuant to the merger agreement. If you

hold your shares of Thomas Weisel Partners common stock in certificated form, any dividends or distributions declared after the effective time of the merger with respect to Stifel common stock will accrue but will not be paid with respect to your shares until you have provided to the exchange agent or Stifel your signed letter of transmittal and any other items specified by the letter of transmittal with respect to your shares of Thomas Weisel Partners common stock.

Subject to the effect of applicable laws, following surrender or delivery, as applicable, of a certificate of shares of Thomas Weisel Partners common stock and letter of transmittal or receipt of an “agent’s message” by the exchange agent in the case of a book-entry transfer of uncertificated shares of Thomas Weisel Partners common stock to the exchange agent or Stifel, there will be issued and/or paid to the holder of such ownership evidence representing whole shares of Stifel common stock issued in exchange therefor, without interest, (A) at the time of such surrender or delivery, as the case may be, the dividends or other distributions with a record date at or after the effective time and a payment date on or prior to the date of issuance of such whole shares of Stifel common stock and not previously paid and (B) at the appropriate payment date, the dividends or other distributions payable with respect to such whole shares of Stifel common stock with a record date at or after the effective time on the closing date of the merger but with a payment date subsequent to surrender or delivery and not previously paid.

There can be no assurance that any regular quarterly dividends will be declared or paid by Stifel following the effective time of the merger, or as to the amount or timing of such dividends, if any. Any future dividends will be made at the discretion of the Stifel board of directors. Prior to the effective time of the merger, Thomas Weisel Partners may not declare or pay any dividends or distributions on its common stock without Stifel’s prior written consent which is not to be unreasonably withheld or delayed by Stifel, other than dividends or distributions by any of its wholly-owned subsidiaries.

Conduct of Business Prior to Closing

Thomas Weisel Partners has agreed in the merger agreement that, until the earlier of the effective time of the merger and termination of the merger agreement, Thomas Weisel Partners will and will cause each of its subsidiaries to conduct its business in the ordinary course consistent with past practice and in compliance with all material applicable laws and governmental authorizations, and use its reasonable best efforts to preserve intact its present business organization, maintain in effect all of its material foreign, federal, state and local licenses, permits, consents, franchises, approvals and authorizations, keep available the services of its directors, officers and employees and maintain existing relations with its customers, lenders suppliers and others having material business relationships with it.

agree, resolve or commit to do any of the foregoing with an effective date prior to the effective time of the merger.

Agreement to Use Reasonable Best Efforts

Subject to the terms and conditions of the merger agreement, each of Stifel and Thomas Weisel Partners has agreed to use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations to consummate the merger and the other transactions contemplated by the merger agreement.

The merger agreement provides that if any governmental authority, including any antitrust authority, seeks amendments to the transactions contemplated by the merger agreement or commitments to be undertaken by any party as a condition to refraining from seeking to block such transactions, allowing the applicable waiting period to expire or releasing such governmental authority’s consent with respect to such transactions, Stifel and Thomas Weisel Partners will commence and conduct good faith negotiations with each other for no less than fifteen (15) days and use their reasonable best efforts to agree upon amendments to the merger agreement which are necessary in order to resolve the issues raised by such governmental authority and permit the consummation of the transactions contemplated thereby. However, neither Stifel nor Thomas Weisel Partners is required to agree to any material divestiture, sale, license or lien of any of their properties, assets or businesses or the imposition of any material limitation on the ability of any of the foregoing to conduct their respective businesses or to own or exercise control of their respective assets and properties.

Agreement Not to Solicit Other Offers

The Thomas Weisel Partners board of directors adopted a resolution recommending that the Thomas Weisel Partners stockholders adopt the merger agreement. Thomas Weisel Partners has agreed that it will not, it will cause its subsidiaries and its and their officers and directors not to, and it will direct, and use its reasonable best efforts to cause, its employees, investment bankers, attorneys, accountants, consultants and other agents, advisors or representatives not to, directly or indirectly:

•

solicit, initiate or knowingly take any action that it knows or reasonably should know would facilitate or encourage the submission of any acquisition proposal (as defined below);

•

enter into or participate in any discussions or negotiations with, furnish any information relating to Thomas Weisel Partners or any of its subsidiaries or afford access to the business, properties, assets, books or records of Thomas Weisel Partners or any of its subsidiaries to, otherwise cooperate in any way with, or knowingly assist, participate in, facilitate or encourage any effort by any third party that is seeking to make, or has made, an acquisition proposal;

•

fail to make, withdraw or modify in a manner adverse to Stifel or publicly propose to withdraw or modify in a manner adverse to Stifel the recommendation from the board of directors of Thomas Weisel Partners to proceed with the merger (with a neutral position or no position with respect to any acquisition proposal considered an adverse modification, subject to certain exceptions), recommend, adopt or approve or publicly propose to recommend, adopt or approve an acquisition proposal, or take any action or make any statement inconsistent with recommendation from the board of directors of Thomas Weisel Partners to proceed with the merger (any of these actions being referred to as an “adverse recommendation change”);

•

grant any waiver or release under any standstill or similar agreement with respect to any class of equity securities of Thomas Weisel Partners or any of its subsidiaries; or

•

enter into any agreement in principle, letter of intent, term sheet, merger agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement or other similar instrument constituting or relating to an acquisition proposal.

Thomas Weisel Partners has agreed to cease immediately and cause to be terminated any and all existing activities, discussions or negotiations, if any, with any third party conducted prior to the date of the merger agreement with respect to any acquisition proposal. During the term of the merger agreement Thomas Weisel Partners may not take any actions to make any state takeover statute (including any Delaware state takeover statute) or similar statute inapplicable to any acquisition proposal.

However, prior to the adoption of the merger agreement by Thomas Weisel Partners’ stockholders, the board of directors of Thomas Weisel Partners may, directly or indirectly through advisors, agents or other intermediaries, subject to compliance with the merger agreement:

•

engage in negotiations or discussions with any third party that has made after the date of the merger agreement a superior proposal (as defined below) or an unsolicited bona fide acquisition proposal that the board of directors of Thomas Weisel Partners reasonably believes (after considering the advice of a financial advisor of nationally recognized reputation and outside legal counsel) is reasonably likely to lead to a superior proposal;

•

thereafter furnish to such third party nonpublic information relating to Thomas Weisel Partners or any of its subsidiaries pursuant to a confidentiality agreement with terms no less favorable to Thomas Weisel Partners than those contained in the confidentiality agreement between Thomas Weisel Partners and Stifel (subject to certain exceptions); and

•

following receipt of a superior proposal or a change of circumstances, make an adverse recommendation change,

but in each case referred to in the foregoing bullet points, only if the board of directors of Thomas Weisel Partners determines in good faith by a majority vote, after considering advice from outside legal counsel to Thomas Weisel Partners, that such action is required in order for the board of directors to comply with its fiduciary duties under applicable law.

The board of directors of Thomas Weisel Partners may not make an adverse recommendation change unless Thomas Weisel Partners has delivered to Stifel a prior written notice advising Stifel that it intends to take such action. Thomas Weisel Partners must notify Stifel promptly (but in no event later than 24 hours) after receipt by Thomas Weisel Partners of any acquisition proposal, any indication that a third party is considering making an acquisition proposal or of any request for information relating to Thomas Weisel Partners by any third party that may be considering making, or has made, an acquisition proposal, which notice must be provided orally and in writing and must identify the third party making, and the material terms and conditions of, any such acquisition proposal, indication or request (including any changes thereto). Thomas Weisel Partners must keep Stifel fully informed, on a current basis, of the status and details of any such acquisition proposal, indication or request and must promptly (but in no event later than 24 hours after receipt) provide to Stifel copies of all significant correspondence and written materials sent or provided to Thomas Weisel Partners or any of its subsidiaries that describes any terms or conditions of any acquisition proposal.

As used in the merger agreement, an “acquisition proposal” means any offer or proposal for, or any third party indication of interest in:

•

any acquisition or purchase, direct or indirect, of 15% or more of the consolidated assets of Thomas Weisel Partners and its subsidiaries or 15% or more of any class of equity or voting securities of Thomas Weisel Partners or any of its subsidiaries whose assets, individually or in the aggregate, constitute 15% or more of the consolidated assets of Thomas Weisel Partners;

•

any tender offer or exchange offer that, if consummated, would result in any person becoming the beneficial owner of 15% or more of any class of equity or voting securities of Thomas Weisel Partners or any of its subsidiaries whose assets, individually or in the aggregate, constitute 15% or more of the consolidated assets of Thomas Weisel Partners; or

•

a merger, consolidation, share exchange, business combination, sale of substantially all the assets, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving Thomas Weisel Partners or any of its subsidiaries whose assets, individually or in the aggregate, constitute 15% or more of the consolidated assets of Thomas Weisel Partners.

As used in the merger agreement, “superior proposal” means any bona fide, written unsolicited acquisition proposal (except that all references to “15% or more” in the definition of acquisition proposal will be deemed to be references to “more than 50%”) on terms that the board of directors of Thomas Weisel Partners determines in

good faith by a majority vote, after considering the advice of a financial advisor of nationally recognized reputation and outside legal counsel and taking into account all the terms and conditions of the acquisition proposal would result in a transaction:

•

that if consummated, is more favorable to Thomas Weisel Partners’ stockholders from a financial point of view than the merger or, if applicable, any proposal by Stifel to amend the terms of the merger agreement taking into account all the terms and conditions of such proposal and the merger agreement (including the expected timing and likelihood of consummation, taking into account any governmental and other approval requirements);

•

that is reasonably capable of being completed on the terms proposed (taking into account the identity of the person making the proposal, approval requirements and all other financial, legal and other aspects of the proposal); and

•

for which financing, if it is wholly or partially a cash transaction, is fully committed or reasonably determined by the board of directors of Thomas Weisel Partners to be available.

Employee Matters

Following the completion of the merger, Stifel will cause to be provided to each individual who is employed by Stifel and its subsidiaries immediately prior to the completion of the merger (other than those individuals covered by collective bargaining agreements) and who remain employed with the surviving corporation or any of its subsidiaries compensation and employee benefits substantially comparable in the aggregate, at Parent’s election, to (i) the compensation (including base salary and participation in bonus programs) and benefits provided to such employees under Thomas Weisel Partners’ employee benefits plans immediately prior to the completion of the merger or (ii) the compensation and benefits provided by Stifel under the employee benefit plans and programs generally made available to similarly situated employees of Stifel and its subsidiaries.

With respect to any employee benefit plan in which any such affected employee first becomes eligible to participate following the completion of the merger, Stifel will: (i) waive all pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to such employee under any health and welfare employee benefit plans of Stifel in which such employee may be eligible to participate following the completion of the merger and (ii) recognize service of such employees (or otherwise credited by Thomas Weisel Partners or its subsidiaries) accrued prior to the completion of the merger for purposes of eligibility to participate, vesting and level of benefits (but not for the purposes of benefit accrual under defined benefit pension plans) under any Stifel employee benefits plans which such employees may be eligible to participate after the completion of the merger, provided, however, that in no event will Stifel give any credit to the extent it would result in the duplication of benefits for the same period of service.

From the date of the completion of the merger through the first anniversary of the closing date, Stifel will provide, or will cause to be provided, to such employees who remain employed with Stifel or its subsidiaries, compensation and benefits at the level initially established as described above. Prior to the completion of the merger, Stifel will establish reasonable severance policies to facilitate the transition of Thomas Weisel Partners’ operations following completion of the merger, which severance policies will be reasonably comparable to the severance benefits available to similarly situated employees of Stifel.

Other Covenants and Agreements

The merger agreement contains certain other covenants and agreements relating to, among other things:

Thomas Weisel Partners Stockholders Meeting

Thomas Weisel Partners has agreed to use its reasonable best efforts to obtain stockholder approval of the merger agreement and the merger.

	Rights of Stifel Stockholders	Rights of Thomas Weisel Partners Stockholders
	in that year will be elected to hold office for a term of 3 years (and until their respective successors have been elected and qualified or until their earlier death, resignation or removal), so that the term of one class of directors will expire each year.

	Because the board of directors of Stifel is classified, under the DGCL directors may be removed from office only for cause by a majority stockholder vote.	Under the certificate of incorporation of Thomas Weisel Partners, any director or directors elected by holders of preferred stock voting separately as a class may be removed, with or without cause, by the holders of a majority of the voting power of all outstanding shares of stock of Thomas Weisel Partners entitled to vote separately as a class in an election of such directors.

Vacancies	Stifel’s certificate of incorporation provides that in the case of any vacancies, by reason of an increase in the number of directors or resignation or otherwise, directors to fill such vacancies may be elected by the majority of the directors then in office, to hold office until the next election of the class for which such directors have been chosen.

Under the certificate of incorporation of Thomas Weisel Partners, vacancies and newly created directorships resulting from any increase in the authorized number of directors or from any other cause (other than vacancies and newly created directorships which the holders of any class or classes of stock or series thereof are expressly entitled by the certificate of incorporation to fill) will be filled by, and only by, a majority of the directors then in office, although less than a quorum, or by the sole remaining director. Any director appointed to fill a vacancy or a newly created directorship will hold office until the next annual meeting of stockholders,

		and until his or her successor is elected and qualified or until his or her earlier resignation or removal.

Limitation on Liability of Directors	Under the certificate of incorporation of Stifel, a director of Stifel will not be personally liable to the stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director’s duty of loyalty to Stifel or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 147 of the DGCL, or (iv) for any transaction from which the director derived an improper personal benefit.	Under the certificate of incorporation of Thomas Weisel Partners, a director will not be liable to Thomas Weisel Partners or its stockholders for monetary damages for breach of fiduciary duty to the fullest extent permitted by the DGCL.

Amendment of the Certificate of Incorporation	Thomas Weisel Partners and Stifel do not have provisions governing amendment of the certificate of incorporation, therefore, the default rules of the DGCL apply.

PROPOSAL TWO: ADJOURNMENT OF THE ANNUAL MEETING

Adjournment of the Meeting

Although it is not currently expected, the Annual Meeting may be adjourned to solicit additional proxies if there are not sufficient votes to approve and adopt the merger agreement and approve the merger. In that event, Thomas Weisel Partners may ask its stockholders to vote upon the proposals to elect directors to the Thomas Weisel Partners board of directors, ratify the appointment of Deloitte & Touche LLP as Thomas Weisel Partners’ independent registered public accounting firm for 2010 and consider the adjournment of the Annual Meeting to solicit additional proxies, but not the proposal to approve and adopt the merger agreement and approve the merger.

In this proposal, we are asking you to authorize the holder of any proxy solicited by the Thomas Weisel Partners board of directors to vote in favor of granting discretionary authority to the proxies to adjourn the Annual Meeting, if necessary, for any purpose, including to solicit additional proxies. If Thomas Weisel Partners stockholders approve the adjournment proposal, we could adjourn the Annual Meeting and any adjourned session of the Annual Meeting and use the additional time to solicit additional proxies, including the solicitation of proxies from stockholders that have previously returned properly executed proxies or authorized a proxy by telephone or via the Internet website. Additionally, we may seek to adjourn the Annual Meeting if a quorum is not present at the Annual Meeting.

Vote Required and Board Recommendation

A majority of the votes cast “FOR” or “AGAINST” the proposal to adjourn the meeting must be voted “FOR” the proposal to adjourn the meeting for it to pass. No proxy that is specifically marked “AGAINST” approval and adoption of the merger agreement and approval of the merger will be voted in favor of the adjournment proposal, unless it is specifically marked “FOR” the proposal to adjourn the meeting.

The Thomas Weisel Partners board of directors recommends that you vote “FOR” the proposal to adjourn the meeting, if necessary, for any purpose, including to solicit additional proxies if there are not sufficient votes to approve and adopt the merger agreement and approve the merger.

We have no reason to believe that any nominee for director, if elected, would not serve. While the board of directors does not anticipate that any of the nominees will be unable to stand for election as a director at the Annual Meeting, if that occurs, your vote (through your proxy) will be voted in favor of such other person or persons who are recommended by our Corporate Governance and Nominations Committee and designated by the board of directors.

Vote Required

You may vote “FOR” or “WITHHOLD” with respect to any or all director nominees. The election of a director requires a plurality of the votes that are cast “FOR” the election of directors. Accordingly, the eight nominees receiving the highest number of votes “FOR” will be elected. A properly executed proxy marked “WITHHOLD” with respect to the election of one or more directors will not be voted with respect to the director or directors indicated, and because there are eight nominees for eight director positions, “WITHHOLD” votes will have no effect on the outcome of the vote for the election of directors. If you sign and send in your proxy card and do not indicate how you want to vote, your proxy will be counted voted as the Thomas Weisel Partners board of directors recommends, which is FOR the election of each of the eight nominees for director named above.

112

Recommendation of the Thomas Weisel Partners Board of Directors

The Thomas Weisel Partners board of directors unanimously recommends a vote FOR the election of each of Mr. Weisel, Mr. Barger, Mr. Allen, Mr. Brown, Mr. Grady, Mr. Hagopian, Mr. Irby and Mr. Koogle to the Thomas Weisel Partners board of directors.

Independence of Non-Employee Directors

Our board of directors and Corporate Governance and Nominations Committee has analyzed the independence of each nominee for the board of directors and has determined that each of our nominees, other than Mr. Weisel is independent of us under both our Standards Regarding Director Independence Determinations and the applicable NASDAQ Stock Market listing standards. In addition, our board of directors and its Corporate Governance and Nominations Committee have determined that each current and proposed member of the Audit Committee is “independent” under the SEC’s audit committee independence standards and that each member of our Compensation Committee is an “outside director” within the meaning of Section 162(m) of the Internal Revenue Code. Our Standards Regarding Director Independence Determinations are available in the “Investor Relations—Corporate Governance” section of our website at www.tweisel.com.

In connection with the independence determinations, our Corporate Governance and Nominations Committee and the board of directors considered all of the relationships between each independent director and us, and in particular the following types of relationships: (i) brokerage and investment banking relationships between us and any independent director, their family members and entities any of them are affiliated with or in which they are significantly invested, (ii) relationships between us and any third-party vendor that is affiliated with any independent director or any of their family members or in which any of them are significantly invested and (iii) relationships with Deloitte & Touche LLP, Thomas Weisel Partners’ independent auditors.

Board Leadership Structure

Our Board currently consists of seven independent directors and one employee director. Mr. Weisel has served as our Chairman and Chief Executive Officer since October 1998. Beginning September 2009, the Board has designated one of the independent directors as Lead Director. We believe that the number of independent, experienced directors that make up our Board, along with the independent oversight of our Lead Director, benefits us and our stockholders. While different board leadership structures may be appropriate for other companies in different situations, we believe our current Board leadership structure, with its strong emphasis on Board independence, provides effective independent oversight of management, while allowing both the Board and management to benefit from Mr. Weisel’s 30 plus years of experience in the industry. In addition, we believe that having a single leader for both Thomas Weisel Partners and the Board eliminates the potential for confusion or duplication of efforts, and provides clear leadership for Thomas Weisel Partners. We believe Thomas Weisel Partners, like many U.S. companies, has been well-served by this leadership structure.

Because the positions of Chairman of the Board and Chief Executive Officer are held by the same person, the Board believes it is appropriate for the independent directors to elect one independent director to serve as a Lead Director. The Lead Director’s responsibilities include (1) being available to discuss with the other directors concerns they may have about Thomas Weisel Partners and its performance and relaying these concerns, where appropriate, to the full Board; (2) being available to consult with the Chief Executive Officer regarding the concerns of the directors; (3) being available to be consulted by the senior executives of Thomas Weisel Partners as to concerns they may have; and (4) presiding at executive sessions of the Board.

Risk Oversight

Our Board does not have a separate risk committee, but instead believes that the entire Board is responsible for overseeing Thomas Weisel Partners’ risk management. Accordingly, our Board, in conjunction with our senior management, is actively involved in overseeing Thomas Weisel Partners’ risks. At a company-wide level, the Board and Thomas Weisel Partners have implemented policies and procedures providing guidelines for their

113

employees in their day-to-day activities. These include but are not limited to Thomas Weisel Partners’ Code of Conduct and Ethics, Anti-Money Laundering Policy, Chinese Wall Procedures, Identity Theft Prevention Program, Privacy Policy and Procedures for Treatment of Complaints and Incident Reports. In addition, the management structure of each of Thomas Weisel Partners’ business lines is designed to manage risk on a daily basis, with members of Thomas Weisel Partners’ senior management having ultimate responsibility for those business lines. Thomas Weisel Partners’ senior management provides regular reports to the Board of any material issues and material risks within the business lines and the degree of its exposure to those risks. These issues are discussed with the Board to ensure that management is properly focused on risk. As a tool to help provide oversight over Thomas Weisel Partners’ market and strategic risks, the Board also reviews business plans for Thomas Weisel Partners as a whole.

The Board also receives risk-related information from each of Thomas Weisel Partners’ compliance, internal audit and legal functions. On a quarterly basis, the compliance department presents a summary of all regulatory inquiries and material incidents reported to the Compliance department during that quarter and provides an annual compliance report. The legal department provides a quarterly summary of Thomas Weisel Partners’ new, ongoing and potential litigation and regulatory actions and a report on Thomas Weisel Partners’ Whistleblower Program. The internal audit department reports directly to the Board’s Audit Committee and is responsible for independently assessing the controls that allow for management and monitoring of Thomas Weisel Partners’ risk. The internal audit department provides the Audit Committee with an annual firm-wide risk assessment, based on the COSO model, performs reviews and audits as directed and as part of an annual audit program and participates in Thomas Weisel Partners’ compliance with the Sarbanes-Oxley Act. In addition to these regular reports, material risks identified by these departments are communicated to the Board as they arise.

In addition, each of our Board committees considers risk within its area of responsibility. For instance, our Audit Committee is apprised quarterly of significant accounting matters and of areas wherein management exercises judgment in the determination of accounting estimates including the value of assets and liabilities and the recognition of revenue and expenses. In addition, they discuss legal and compliance matters, and assess the adequacy of our risk-related internal controls. The Audit Committee also requests management to address specific risk issues at its meetings. Likewise, the Compensation Committee considers risk and structures our compensation programs with an eye to providing incentives to appropriately reward growth without undue risk taking. On an annual basis, the Corporate Governance and Nominations Committee reviews our Company’s and Board Committees’ structure to ensure appropriate oversight of risk.

Board Committees

Our board of directors held five meetings during 2009. Each of our directors, other than Mr. Koogle, attended at least 80% in the aggregate of the total number of meetings of the board of directors and the committees of the board of directors on which he served during 2009. Attendance at board of directors and committee meetings during 2009 averaged above 87% for our directors as a group. We encourage our directors to attend annual meetings of stockholders and we have scheduled our 2010 second quarter board of directors and committee meetings to coincide with the Annual Meeting. All of our directors attended our last annual meeting of stockholders. Information about how to communicate with our board of directors or any member or committee of the board of directors is set forth herein under “Communicating with the Board of Directors”.

The Audit Committee is also responsible for the engagement and oversight of Thomas Weisel Partners’ independent auditors, the scope of the audit to be undertaken by our auditors and the pre-approval of any audit and permitted non-audit services provided by such auditors. Our Audit Committee has a charter that is available in the “Investor Relations—Corporate Governance” section of our website at http://www.tweisel.com.

The head of our internal audit department also reports directly to the Audit Committee and, when appropriate, participates in executive sessions with the Audit Committee.

Compensation Committee. In compliance with the applicable rules of the NASDAQ Stock Market, our Compensation Committee is currently comprised of three independent directors, who currently are Mr. Barger, Mr. Irby and Mr. Koogle. Mr. Irby is the Chairman of our Compensation Committee. If all of our director nominees are elected, then effective immediately after our Annual Meeting, the membership of our Compensation Committee would not change and the Compensation Committee would continue to consist of the following three independent directors: Mr. Irby (Chair), Mr. Barger and Mr. Koogle.

Our board of directors has determined that each current and prospective member of our Compensation Committee is an “outside director” within the meaning of Section 162(m) of the Internal Revenue Code.

Our Compensation Committee reviews and, as it deems appropriate, recommends to the board of directors policies, practices and procedures relating to the compensation of our executive officers. The Compensation Committee also exercises all authority under our Equity Incentive Plan. From time to time, and in connection with the determination of bonus payments, the Compensation Committee approves an aggregate bonus or equity award pool and delegates to management the authority to allocate such aggregate amounts among individual employees other than executive officers. During 2009, our Compensation Committee met 10 times. Our Compensation Committee has the authority under its charter to delegate all or a portion of its duties and responsibilities to a subcommittee of the Compensation Committee. Our Compensation Committee has a charter that is available in the “Investor Relations—Corporate Governance” section of our website at http://www.tweisel.com.

In accordance with our Corporate Governance Guidelines, qualified candidates for membership on our board of directors are identified and recommended by the Corporate Governance and Nominations Committee. The Board and the Corporate Governance and Nominations Committee believe that sound governance of our Company in an increasingly complex landscape requires a wide diversity of viewpoints, backgrounds, skills, and experiences. While the Corporate Governance and Nominations Committee does not have a formal policy regarding board diversity, the Corporate Governance and Nominations Committee strives to encourage diversity on the Board by basing its nominations on the following criteria:

•

Judgment, character, expertise, skills and knowledge useful to the oversight of our business;

•

Diversity of viewpoints, backgrounds, experiences and other demographics;

•

Business or other relevant experience; and

•

The extent to which the interplay of the candidate’s expertise, skills, knowledge and experience with that of other members of the board of directors will build a board of directors that is effective, collegial and responsive to the needs of Thomas Weisel Partners.

Under our Corporate Governance Guidelines, the Corporate Governance and Nominations Committee will evaluate candidates for Board membership nominated by stockholders in accordance with our bylaws in the same manner as other candidates identified by or to the Corporate Governance and Nominations Committee. Under its charter, the Corporate Governance and Nominations Committee may retain outside consultants to assist in identifying candidates; however, during 2009 no outside consultant was retained for this purpose.

PROPOSAL FOUR: RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

The Audit Committee of the Thomas Weisel Partners board of directors has appointed Deloitte & Touche LLP as Thomas Weisel Partners’ independent auditors for our fiscal year ending December 31, 2010. The Thomas Weisel Partners board of directors is submitting this appointment of independent auditors for stockholder ratification at the Annual Meeting.

A representative of Deloitte & Touche LLP is expected to be present at the Annual Meeting, will have the opportunity to make a statement if he or she desires to do so and will be available to respond to appropriate questions from stockholders.

Neither applicable law nor our organizational documents require that Thomas Weisel Partners stockholders ratify the appointment of Deloitte & Touche LLP as Thomas Weisel Partners’ independent auditors, however, the Thomas Weisel Partners Audit Committee believes that it is consistent with good corporate practice to allow stockholders an opportunity to express their views on this appointment. If the stockholders do not ratify the appointment of Deloitte & Touche LLP as Thomas Weisel Partners’ independent auditors for 2010, the Thomas Weisel Partners Audit Committee will reconsider whether or not to continue the engagement of Deloitte & Touche LLP. Even if the appointment of Deloitte & Touche LLP is ratified, the Thomas Weisel Partners Audit Committee, in its discretion, may discontinue the engagement of Deloitte & Touche LLP and engage different independent auditors at any time during the year if it determines that such a change is necessary or appropriate at such time.

Fees Paid to Independent Auditors

The following table shows information about fees paid by us to Deloitte & Touche LLP and the other member firms of Deloitte Touche Tohmatsu and their respective affiliates (which we refer to collectively as Deloitte entities) with respect to the periods indicated. The Thomas Weisel Partners Audit Committee’s policy is to pre-approve all audit and non-audit services performed by our independent registered public accounting firm in order to ensure that they do not impair its independence from us. All of the fees described in the table below were pre-approved by the Thomas Weisel Partners Audit Committee. In addition, the Thomas Weisel Partners Audit Committee has pre-approved certain additional advisory services which may be provided by Deloitte & Touche LLP in the future.

INFORMATION CONCERNING THOMAS WEISEL PARTNERS GROUP, INC. BOARD AND MANAGEMENT

Other Relationships with Our Directors and Executive Officers

Director and Officer Indemnification. We have entered into agreements that provide indemnification to our directors, officers and other persons requested or authorized by our board of directors to take actions on behalf of us for all losses, damages, costs and expenses incurred by the indemnified person arising out of such person’s service in such capacity, subject to the limitations imposed by Delaware law. These agreements are in addition to our indemnification obligations under our bylaws.

Tax Indemnification Agreement and Related Matters. An entity that has historically operated in corporate form generally is liable for any adjustments to the corporation’s taxes for periods prior to its initial public offering. In contrast, the members of Thomas Weisel Partners Group LLC, our predecessor, rather than us, generally will be liable for adjustments to taxes (including U.S. federal and state income taxes) attributable to the operations of Thomas Weisel Partners Group LLC and its affiliates prior to our initial public offering. In connection with our initial public offering, we entered into a tax indemnification agreement to indemnify the members of Thomas Weisel Partners Group LLC against certain increases in taxes that relate to activities of Thomas Weisel Partners Group LLC and its affiliates prior to our initial public offering. The tax indemnification agreement includes provisions that permit us to control any tax proceeding or contest which might result in being required to make a payment under the tax indemnification agreement.

Private Equity Funds. We have established private equity funds in order to permit our employees to participate in our private equity, venture capital and other similar activities. Many of our employees, their spouses or entities owned or controlled by the employees have invested in these funds. Our affiliates generally bear overhead and administrative expenses for, and may provide certain other services free of charge to, the funds. In addition, certain of our directors and executive officers from time to time invest their personal funds directly in other funds managed by our subsidiaries or affiliates on the same terms and with the same conditions as the other investors in these funds, who are not our directors, executive officers or employees.

Other Transactions. Certain of our directors and officers and entities affiliated with our directors maintain brokerage accounts with us and maintain investments in investment funds that we manage. In addition, companies that our directors are investors in, or are directors or officers of, from time to time engage in transactions with us, including, for example, to provide us with software and data services and staffing services and retaining us with respect to the provision of investment banking services.

Review and Approval of Transactions with Related Persons

Under our Audit Committee Charter, our Audit Committee is responsible for reviewing and approving all related-party transactions that are required to be disclosed under Item 404 of the SEC’s Regulation S-K, and to ratify all other related party transactions of Thomas Weisel Partners. Factors taken into account in the review of related party transactions include our Code of Conduct and Ethics, our Standards Regarding Director Independence and our Corporate Governance Guidelines. Transactions with related persons that were entered into prior to our initial public offering and conversion to a corporation in February 2006 were not approved by our Audit Committee.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act requires our executive officers and directors and persons who beneficially own more than 10% of Thomas Weisel Partners common stock to file initial reports of beneficial ownership and reports of changes in beneficial ownership with the SEC. Such persons are required by SEC regulations to furnish us with copies of all Section 16(a) forms filed by such persons.

121

Based solely on our review of the copies of all Section 16(a) forms furnished to us and other information, we believe that all filing requirements applicable to our executive officers, directors and greater-than-10% stockholders were met with three exceptions—(i) on March 9, 2009 a transaction took place requiring the filing of a Form 4 for Mr. Weisel, the Chief Executive Officer of Thomas Weisel Partners, by March 11, 2009, the Form 4 was inadvertently filed late on March 13, 2009; (ii) on March 26, 2009 a transaction took place requiring the filing of a Form 4 for Paul C. Slivon, an officer of Thomas Weisel Partners, by March 30, 2009, the Form 4 was inadvertently filed late on May 11, 2009; and (iii) on June 24, 2009 a transaction took place requiring the filing of a Form 4 for Mr. Slivon by June 26, 2009, the Form 4 was inadvertently filed late on June 29, 2009.

Shaugn Stanley, our former Chief Financial Officer, also served as our Chief Administrative Officer during 2009.

those employees who had given notice of an intention to terminate their employment prior to April 23, 2010). The waiver was effective as of April 23, 2010 and eliminated any continued employment service requirements for vesting under Section 11(d)(i) of Thomas Weisel Partners’ Third Amended and Restated Equity Incentive Plan, if and so long as (but only for so long as) the holder of such restricted stock unit refrains from engaging in a competitive activity or a soliciting activity prior to the relevant vesting date or dates of such awards. As a result of the waiver of any continued employment service requirements for vesting, Thomas Weisel Partners immediately recognized the remaining non-cash share based compensation expense for these grants of restricted stock unit awards that were subject only to the passage of time. Thomas Weisel Partners estimated the non-cash compensation share based compensation charge to be approximately $55 to $60 million.

Potential Payments Upon Termination or Change-in-Control

Thomas W. Weisel, Chairman and Chief Executive Officer. We have entered into an amended and restated employment agreement with Thomas W. Weisel, our Chairman and Chief Executive Officer, which provides for certain payments and benefits in connection with any termination of Mr. Weisel’s employment. The amended and restated employment agreement is substantially similar to the employment agreement and the first amendment thereto filed as an exhibit to our 2007 Annual Report on Form 10-K (see “Where You Can Find More Information” beginning on page 153), except for changes made to accommodate the new Section 409A rules. A copy of the amended and restated employment agreement with Mr. Weisel is attached as an exhibit to our 2008 Annual Report on Form 10-K. Under the agreement, Mr. Weisel is employed for an initial employment term (ending on December 31, 2009) and, in the absence of a termination of the agreement or of Mr. Weisel’s employment, for subsequent two-year employment terms thereafter. Either we or Mr. Weisel may terminate his employment with us at any time for any reason, or for no reason, subject to 90 days’ advance written notice in most cases.

127

Termination by Us Without Cause or by Mr. Weisel for Good Reason. If Mr. Weisel’s employment is terminated by us without “Cause” or by Mr. Weisel for “Good Reason” (each as defined in his amended and restated employment agreement), Mr. Weisel will be entitled to receive a lump-sum payment from us equal to the sum of the following amounts (which, in each case, we have estimated as if Mr. Weisel had been terminated as of January 1, 2010):

•

Payment for any accrued but unpaid base salary, accrued but unused vacation days, any unpaid expense reimbursements and any other vested or accrued but unpaid compensation and benefits. We estimate that if Mr. Weisel had been terminated as of January 1, 2010, this amount would be approximately $0.

•

Payment, which would be paid on the 60^th day following the date of termination, equal to the remaining base salary from the date of termination through the end of the then-existing employment term. We estimate that if Mr. Weisel had been terminated as of January 1, 2010, this amount would be approximately $400,000.

•

A bonus payment, which would be paid on the 60^th day following the date of termination, at least equal to the average of his bonus amounts for the three fiscal years ending before the termination notice is given, together with a pro-rated bonus for any portion of the then-existing employment period served. We estimate that if Mr. Weisel had been terminated as of January 1, 2010 this amount would have been approximately $706,667.

Payment by us of the above amounts would be subject to the condition that Mr. Weisel execute and deliver to us a release of claims that would release us, our affiliates, and each of our members (and any of their respective past or present officers, directors, employees or agents) from any and all liabilities to Mr. Weisel.

In addition, if Mr. Weisel’s employment is terminated by us without “Cause” or by Mr. Weisel for “Good Reason,” Mr. Weisel would be entitled to (i) full vesting of all outstanding stock options, restricted stock, restricted stock units and other equity-based awards, with stock options remaining exercisable for a period of 12 months after the end of his employment (or, if earlier, until they would have expired but for his termination) and (ii) continued participation for himself, his spouse and his dependants in our employee benefit and welfare plans for 24 months following the date of termination. We estimate that if Mr. Weisel had been terminated as of December 31, 2009, the value of these entitlements would have been approximately $454,012, of which $46,146 is attributable to the estimated cost of providing the employee benefit and welfare plans for a 24-month period and $407,866 is attributable to the value, based on the closing price per share of Thomas Weisel Partners common stock on December 31, 2009, of restricted stock units that were unvested as of December 31, 2009.

Termination by Us for Cause, by Mr. Weisel Without Good Reason or Due to Death or Disability. If Mr. Weisel’s employment is terminated by us for “Cause” or by Mr. Weisel without “Good Reason” or if his employment terminates as a result of his death or disability, Mr. Weisel will be entitled to receive his accrued but unpaid base salary, accrued but unused vacation days, any unpaid expense reimbursements and any other vested or accrued but unpaid compensation and benefits. We estimate that if Mr. Weisel had been terminated as of December 31, 2009, this amount would have been approximately $0.

Other than as described above with respect to Mr. Weisel and as described below with respect to Mr. Conacher, none of our named executive officers is a party to any contract, agreement, plan or arrangement, whether written or unwritten, that provides for any payment to such officer at, following or in connection with any termination of such officer or in connection with a change in control of Thomas Weisel Partners, other than that under certain circumstances outstanding equity awards granted under our Equity Incentive Plan will become fully vested, exercisable and payable in connection with a change in control. If all of the retention-based equity awards held by our named executive officers were to become fully vested, exercisable and payable in connection with a change in control, then, based on the closing price per share of Thomas Weisel Partners common stock on December 31, 2009, the value of these awards would have been as follows: Mr. Weisel—$407,866 (as noted above); Mr. Conacher—$1,264,251 (as noted below); Mr. Stroub—$145,424; Mr. Stanley—$245,730; Mr. Raymond—$773,528 and Mr. Stais—$714,171. In addition, if all of the performance-based equity awards

128

held by our named executive officers were to become fully vested, exercisable and payable in connection with a change in control, then, based on the closing price per share of Thomas Weisel Partners common stock on December 31, 2009, the value of these awards would have been as follows: Mr. Stanley—$283,500; Mr. Raymond—$472,500; and Mr. Stais—$283,500.

The provisions of Mr. Weisel’s employment agreement, including those relating to amounts payable in connection with any termination of Mr. Weisel’s employment, were determined based on arms’ length negotiation and our understanding of market practice for employment terms for similarly situated executive officers at comparable firms.

Lionel F. Conacher, President and Chief Operating Officer. We have entered into an employment agreement with Lionel F. Conacher, our President and Chief Operating Officer, which provides for certain payments and benefits in connection with any termination of Mr. Conacher’s employment. The employment agreement replaces the amended and restated employment agreement and took effect on January 1, 2010. The employment agreement is substantially similar to the amended and restated employment agreement that was filed as an exhibit to our 2008 Annual Report on Form 10-K, except for changes made to remove provisions relating to the “transition period,” which was completed on December 31, 2009.

A copy of the employment agreement with Mr. Conacher is attached as an exhibit to our Current Report on Form 8-K, dated July 29, 2009. Under the agreement, Mr. Conacher will be employed for an initial employment term (ending on December 31, 2011) and, in the absence of a termination of Mr. Conacher’s employment, for subsequent two-year employment terms thereafter. Either we or Mr. Conacher may terminate his employment with us at any time for any reason, or for no reason, subject to 90 days’ advance written notice in most cases.

Termination by Us Without Cause or by Mr. Conacher for Good Reason. If Mr. Conacher’s employment is terminated by Thomas Weisel Partners without “Cause” or by Mr. Conacher for “Good Reason” (each as defined in his employment agreement), Mr. Conacher is entitled to receive a lump-sum payment equal to the sum of the following amounts:

•

Payment for any accrued but unpaid base salary, accrued but unused vacation days, any unpaid expense reimbursements and any other vested or accrued but unpaid compensation and benefits. We estimate that if Mr. Conacher had been terminated as of January 1, 2010, this amount would be approximately $0.

•

Payment, which would be paid on the 60^th day following the date of termination, equal to two years’ base salary. We estimate that if Mr. Conacher had been terminated as of January 1, 2010, this amount would be approximately $400,000.

•

A bonus payment, which would be paid on the 60^th day following the date of termination, equal to the product of (A) the average of the bonuses paid or payable to Mr. Conacher for the two fiscal years ending before notice of termination is given and (B) a multiplier equal to (i) if the termination notice occurs on or prior to December 31, 2011, two and (ii) if the termination notice occurs on or after January 1, 2012, a fraction, the numerator of which is equal to the number of days remaining under his current employment term (but in no event less than 365) and the denominator of which is 365. In calculating Mr. Conacher’s historic bonus, his bonus for 2008 and 2009 is deemed to be $2,400,000. If Mr. Conacher had been terminated as of January 1, 2010, we estimate this amount would be approximately $4,800,000.

Payment by us of the above amounts generally would be subject to the condition that Mr. Conacher execute and deliver to Thomas Weisel Partners a release of claims that would release Thomas Weisel Partners, its affiliates, and each of its members (and any of their respective past or present officers, directors, employees or agents) from any and all liabilities to Mr. Conacher.

129

In addition, if Mr. Conacher’s employment is terminated by us without “Cause” or by Mr. Conacher for “Good Reason,” Mr. Conacher would be entitled to (i) full vesting of all outstanding stock options, restricted stock, restricted stock units and other equity-based awards, with stock options remaining exercisable for a period of 12 months after the end of his employment (or, if earlier, until they would have expired but for his termination), and (ii) continued participation for himself, his spouse and his dependents in our employee benefit and welfare plans for 24 months following the date of termination. We estimate that if Mr. Conacher had been terminated as of January 1, 2009, the value of these entitlements would have been approximately $1,310,397, of which $46,146 is attributable to the estimated cost of providing the employee benefit and welfare plans for a 24-month period and $1,264,251 is attributable to the value, based on the closing price per share of Thomas Weisel Partners common stock on December 31, 2009, of restricted stock units that were unvested as of December 31, 2009 and $0 is attributable to the value, based on the closing price per share of Thomas Weisel Partners common stock on December 31, 2009, of stock options that were unvested as of December 31, 2009.

Termination by Us for Cause, by Mr. Conacher Without Good Reason or Due to Death or Disability. If Mr. Conacher’s employment were terminated by Thomas Weisel Partners for “Cause” or by Mr. Conacher without “Good Reason” or if his employment terminates as a result of his death or disability, Mr. Conacher will be entitled to receive his unpaid base salary for periods prior to the date of termination, and payment for any accrued but unused vacation days, any unpaid expense reimbursements, any unpaid but vested bonus and any other vested or accrued but unpaid compensation and benefits. We estimate that if Mr. Conacher had been terminated as of January 1, 2010, this amount would have been approximately $0.

The provisions of Mr. Conacher’s employment agreement, including those relating to amounts payable in connection with any termination of Mr. Conacher’s employment, were determined based on arms’ length negotiation and our understanding of market practice for employment terms for similarly situated executive officers at comparable firms.

As reported on a Form 8-K filed with the SEC on April 26, 2010, Thomas Weisel Partners announced that Mr. Conacher will be departing Thomas Weisel Partners effective July 22, 2010.

Executive Officer Employment and Other Agreements

Employment Agreements

CEO Employment Agreement. We have entered into an amended and restated employment agreement with Mr. Weisel, our Chairman and Chief Executive Officer. The following is a description of the material terms of our amended and restated employment agreement with Mr. Weisel. You should, however, refer to the exhibits that are a part of our 2009 Annual Report on Form 10-K (see “Where You Can Find More Information” beginning on page 153), for a copy of the employment agreement with Mr. Weisel.

Under the agreement, Mr. Weisel will serve as our Chief Executive Officer for an initial term (ending on December 31, 2009) and, following the initial term, his term of employment has been automatically extended for successive two year periods, subject to early termination pursuant to the agreement and unless otherwise agreed in writing by Mr. Weisel and us 90 days prior to the end of such periods. During Mr. Weisel’s employment period, we will take all reasonable action to cause him to be appointed or elected to our board of directors, and to serve as Chairman of our board of directors, subject to applicable laws, rules and regulations and our corporate governance policies and practices.

Mr. Weisel will be entitled to a base salary of $200,000, payable in semi-monthly installments. In 2009, Mr. Weisel voluntarily agreed to reduce his base salary by 10% to $180,000. Mr. Weisel’s base salary returned to $200,000 on January 1, 2010. The amount of his annual salary is subject to annual review by our Compensation Committee but cannot be decreased. In addition, each year Mr. Weisel may be awarded an annual bonus under our bonus plan for senior executives. Mr. Weisel is also entitled to participate in our group health, dental and life insurance plans, 401(k) savings plan and equity incentive plan, and entitled to vacation benefits, reimbursement of reasonable business expenses, and use of office space, facilities and other support and services on a basis that is at least as favorable as that provided to him on the date of the agreement, subject to periodic review and modification by the Compensation Committee in its sole discretion. Under the agreement, either we or Mr. Weisel may terminate his employment with us at any time for any reason, or for no reason, subject to 90

130

days’ advance written notice in most cases. Further information regarding payments that would be made to Mr. Weisel under his employment agreement upon any termination of Mr. Weisel’s employment are set forth above under “–Potential Payments Upon Termination or Change-in-Control.”

In addition, Mr. Weisel has granted us a license to use his name and certain other names in connection with our current and future business and affairs. He is also subject to the noncompetition, nonsolicitation, liquidated damages, transfer of client relationships and confidentiality provisions contained in the TWP Equity Agreement described below.

President’s Employment Agreement. We have entered into an employment agreement with Lionel F. Conacher, our President and Chief Operating Officer. The following is a description of the material terms of our employment agreement with Mr. Conacher. You should, however, refer to the exhibits that are a part of our 2009 Annual Report on Form 10-K (see “Where You Can Find More Information” beginning on page 153), for a copy of the employment agreement with Mr. Conacher.

Under the agreement, Mr. Conacher served as our President and Chief Operating Officer with all of the duties, responsibilities and authority normally attendant to the office of President. The agreement also provides that Mr. Conacher will be entitled to a base salary of $200,000, which may be increased annually and that Mr. Conacher also will be awarded an annual bonus to be paid in a form consistent with the other members of the Executive Committee. In 2009, Mr. Conacher voluntarily agreed to reduce his base salary by 10% to $180,000. Mr. Conacher’s base salary returned to $200,000 on January 1, 2010. Mr. Conacher will also be entitled to participate in Thomas Weisel Partners equity incentive plans, employee retirement and welfare benefit plans, among other benefits.

The employment agreement with Mr. Conacher also provides for certain payments and benefits in connection with any termination of Mr. Conacher’s employment. Under the agreement, Mr. Conacher will be employed for an initial employment term (ending on December 31, 2011) and, in the absence of a termination of Mr. Conacher’s employment, for subsequent two-year employment terms thereafter. Either Thomas Weisel Partners or Mr. Conacher may terminate his employment at any time for any reason, or for no reason, subject to 90 days’ advance written notice in most cases. Further information regarding payments that would be made to Mr. Conacher under his employment agreement upon any termination of Mr. Conacher’s employment is set forth above under “–Potential Payments Upon Termination or Change-in-Control.”

Partner Employment Agreements. In addition to the employment agreements with Mr. Weisel and Mr. Conacher described above, we have entered into an employment agreement with each of our other employees who was a partner of Thomas Weisel Partners Group LLC prior to its conversion to a corporation in connection with our initial public offering (including each of our named executive officers). The following are descriptions of the material terms of each of these employment agreements. The terms of each such employment agreement are identical. You should, however, refer to the exhibits that are a part of our Annual Report on Form 10-K for a copy of the form of the Partner Employment Agreement. See “Where You Can Find More Information” beginning on page 153.

Each Partner Employment Agreement provides as follows:

Base Salary. Each employee who is a party to a Partner Employment Agreement will be paid an annual base salary of $200,000, payable in semi-monthly installments. In 2009, the base salary for each employee at the vice president level and higher was reduced by 10%. The base salary returned to its normal rate on January 1, 2010. The amount of the annual salary is subject to annual review by us. In addition, annual bonuses may be awarded in excess of base salary.

Benefits. Each employee who is a party to a Partner Employment Agreement will be entitled to participate in our group health, dental and life insurance plans, 401(k) savings plan and equity incentive plan.

131

Termination of Employment. Each employee who is a party to a Partner Employment Agreement may generally be terminated by either that employee or us on 90 days’ prior written notice, subject to the continuing survival of the non-competition, non-solicitation, liquidated damages, transfer of client relationships and confidentiality provisions contained in the TWP Equity Agreement described below, to the extent applicable.

Equity and Pledge Agreements

TWP Equity Agreement

Persons and Shares Covered. We have entered into an equity agreement with each of our employees who was a partner of Thomas Weisel Partners Group LLC prior to its conversion to a corporation in connection with our initial public offering (including each of our named executive officers). We refer to this agreement as the “TWP Equity Agreement.” The shares covered by the TWP Equity Agreement include all shares of Thomas Weisel Partners common stock owned by such an employee as of the completion of our initial public offering on February 7, 2006 (including through indirect ownership and ownership through affiliated entities) and shares received by that employee (directly or indirectly) in exchange for or in respect of his or her shares of Thomas Weisel Partners common stock by reason of stock dividends, stock splits, reverse stock splits, spin-offs, split-ups, recapitalizations, combinations or exchanges of shares, but does not include any restricted stock units awarded to that employee under our Equity Incentive Plan. The shares of Thomas Weisel Partners common stock covered by the TWP Equity Agreement are referred to as “covered shares.” A copy of the form of the TWP Equity Agreement is included as an exhibit to our Annual Report on Form 10-K. See “Where You Can Find More Information” beginning on page 153.

When an employee who is a party to the TWP Equity Agreement ceases to be our employee for any reason other than death or disability, he or she will continue to be bound by all the provisions of the TWP Equity Agreement until that employee holds (directly or indirectly) all covered shares free from the transfer restrictions described below and thereafter he or she will no longer be bound, in general, by the provisions (other than the continuing provisions) of the TWP Equity Agreement.

Transfer Restrictions. Each employee who is a party to the TWP Equity Agreement has agreed, among other things, to:

•

except as described below, not transfer, and to maintain sole beneficial ownership of, his or her covered shares for a period of five years after the completion of our initial public offering on February 7, 2006; provided, however, that each such employee who, in the reasonable judgment of our Underwritten Offering Committee described below, continues to be actively engaged in our business, may transfer up to one third of his or her covered shares following each of the third and fourth anniversaries of the completion of our initial public offering on February 7, 2006 (including any shares sold in underwritten public offerings during the relevant period);

•

comply with the transfer restrictions relating to the covered shares imposed by the lock-up provisions of the underwriting agreement relating to our initial public offering; and

•

comply with other transfer restrictions relating to shares of Thomas Weisel Partners common stock when requested to do so by us and comply with our insider trading policies.

Transfers include, among other things, any disposition of the economic risks of ownership of covered shares, including short sales, option transactions and use of derivative financial instruments or other hedging arrangements with respect to our securities.

Sales Through Underwritten Public Offerings. Our Underwritten Offering Committee may approve one or more underwritten public offerings to sell covered shares during the transfer restrictions period, subject to the restrictions described below. Each employee who is a party to the TWP Equity Agreement and who, in the reasonable judgment of our Underwritten Offering Committee, continues to be actively engaged in our business or has suffered a termination of employment resulting from a disability, or the heir or estate of any partner who has died, will be entitled to participate in such an underwritten public offering on a pro rata basis with the

132

covered shares of all other employees who are a party to the TWP Equity Agreement so participating, or on a lesser basis at his or her request. Our Underwritten Offering Committee currently consists of Thomas W. Weisel, who chairs the committee, Lionel F. Conacher, our President and Chief Operating Officer, Ryan Stroub, our Chief Financial Officer, and Mark P. Fisher, our General Counsel. Approval of an underwritten offering by the committee will require the unanimous approval of the members of the committee. Approval of an underwritten public offering by the committee is subject to the further limitations contained in the TWP Equity Agreement. These underwritten public offerings will be subject to any other registration rights that we have granted or may in the future grant. Covered shares will also be subject to any underwriters’ lock-up then in effect. In addition, subject to the approval of our Underwritten Offering Committee, employees who are a party to the TWP Equity Agreement will have the right to participate in underwritten offerings effected by us for other purposes, subject to the limitations described above and certain other limitations.

Our Underwritten Offering Committee may approve requests by an employee that is a party to the TWP Equity Agreement to transfer covered shares to certain permitted transferees such as family members or family trusts; provided that these transferees will be subject to the same transfer restrictions under the TWP Equity Agreement.

Sales in Compliance With Rule 144 Under the Securities Act. Consistent with the transfer restrictions described above, and other than in compliance with the exceptions described above, employees who are a party to the TWP Equity Agreement generally will not be permitted to transfer covered shares when transfers are restricted under the TWP Equity Agreement through sales effected in compliance with Rule 144 under the Securities Act or otherwise. However, upon a termination of such an employee’s employment due to his or her death or disability, such employee or his or her heirs or estate will be permitted to sell covered shares in compliance with Rule 144, regardless of when such termination of employment occurred.

Compliance with Securities Laws. In addition to the restrictions set forth above, employees who are party to the TWP Equity Agreement will need to comply with applicable securities laws in connection with any transfer of Thomas Weisel Partners common stock and may need to deliver an opinion of counsel in connection with any transfer.

All transfer restrictions applicable to an employee under the TWP Equity Agreement terminate upon the death of such employee or upon a change of control involving us.

Dividends. To the extent dividends are paid on covered shares while an employee remains subject to the transfer restrictions of the TWP Equity Agreement, the employee will be entitled to such dividends.

Voting. Each employee who is a party to the TWP Equity Agreement will be entitled to full voting rights with respect to his or her covered shares.

Confidentiality. Each partner is required to protect and use “confidential information” in accordance with the restrictions placed by us on its use and disclosure.

Noncompetition. Each employee who is a party to the TWP Equity Agreement has agreed that, without our consent, during the period ending 12 months after the date the employee ceases to be employed by us, he or she may not:

•

form, or acquire a 5% or greater ownership, voting or profit participation interest in any competitive enterprise; or

•

associate with any competitive enterprise and in connection with such association engage in, or directly or indirectly manage or supervise personnel engaged in, any activity (i) which is similar or substantially related to any activity in which that employee was engaged, in whole or in part, at Thomas Weisel Partners, (ii) for which that employee had direct or indirect managerial or supervisory responsibility at Thomas Weisel Partners or (iii) which calls for the application of the same or similar specialized knowledge or skills as those utilized by that employee in his or her activities at Thomas Weisel Partners.

133

When we refer to a “competitive enterprise,” we are referring to any business enterprise that engages in, or owns a significant interest in any entity that engages in, financial services such as investment banking, public or private finance, financial advisory services, private investing, merchant banking, asset or hedge fund management, securities brokerage, sales, lending, custody, clearance, settlement or trading.

Nonsolicitation. During the period ending 12 months after the date an employee who is a party to the TWP Equity Agreement ceases to be employed by us, that employee may not, directly or indirectly, in any manner:

•

solicit any client with whom that employee worked, or whose identity became known to him or her in connection with his or her employment with Thomas Weisel Partners, to transact business with a competitive enterprise or reduce or refrain from doing any business with Thomas Weisel Partners;

•

interfere with or damage any relationship between Thomas Weisel Partners and any client or prospective client; or

•

solicit any of our employees to apply for, or accept employment with, any competitive enterprise.

Transfer of Client Relationships. Each employee who is a party to the TWP Equity Agreement is required, upon termination of his or her employment, to take all actions and do all things reasonably requested by us during a 90-day cooperation period to maintain for us the business, goodwill and business relationships with our clients with which he or she worked.

Liquidated Damages. In the case of any breach of the non-competition or non-solicitation provisions contained in the TWP Equity Agreement prior to the fifth anniversary of the date of the completion of our initial public offering on February 7, 2006, the breaching employee will be liable for liquidated damages. The liquidated damages obligation of each employee who is a party to the TWP Equity Agreement is secured by 50% of Thomas Weisel Partners common stock owned by that employee (including through indirect ownership and ownership through affiliated entities) at the time of the completion of our initial public offering on February 7, 2006.

Term and Amendment. The TWP Equity Agreement will be in effect for ten years from the date of the completion of our initial public offering on February 7, 2006 or until it is earlier terminated by us. An employee seeking a waiver from the TWP Equity Agreement generally requires our consent, and the TWP Equity Agreement may be amended only with approval of our board of directors.

TWP Pledge Agreements. Each of our employees who is a party to the TWP Equity Agreement has entered into a pledge agreement with us that will secure the liquidated damages provisions in the TWP Equity Agreement by a pledge of 50% of the shares of Thomas Weisel Partners common stock owned by him or her (including through indirect ownership and ownership through affiliated entities) at the time of the completion of our initial public offering on February 7, 2006. These pledges of Thomas Weisel Partners common stock will terminate on the earliest to occur of:

•

the death of the relevant employee;

•

the expiration of the 12-month period following the termination of the employment of the relevant employee; or

•

the fifth anniversary of the date of the completion of our initial public offering on February 7, 2006 (unless employment has been terminated earlier).

The liquidated damages provisions in the TWP Equity Agreement are in addition to the forfeiture of any future equity-based awards that may occur as a result of the breach of any non-competition or non-solicitation provisions contained in those awards. The liquidated damages and pledge arrangements do not preclude us from seeking any injunctive relief to which we may be entitled for a breach of the non-competition or non-solicitation provisions.

A copy of the form of the Pledge Agreement is included as an exhibit to our Annual Report on Form 10-K. See “Where You Can Find More Information” beginning on page 153.

Westwind Equity Agreement

Persons and Shares Covered. We have entered into an equity agreement with substantially all of the persons who were shareholders of Westwind prior to our acquisition of Westwind. We refer to this agreement as the “WW Equity Agreement.” The shares covered by the WW Equity Agreement include all shares of Thomas Weisel Partners common stock and all exchangeable shares acquired in exchange for the shares of Westwind that the parties to the WW Equity Agreement held when we acquired Westwind (and shares of Thomas Weisel Partners common stock received in exchange for exchangeable shares). The shares of stock covered by the WW Equity Agreement are referred to below as “covered shares.” In this section, Westwind shareholders refers to those shareholders party to the WW Equity Agreement.

Transfer Restrictions. Except as described below, each Westwind shareholder has agreed, among other things, to maintain sole beneficial ownership of and not to transfer his or her covered shares until February 7, 2011.

Exceptions to Transfer Restrictions. Parties to the WW Equity Agreement generally would be able to transfer their shares pursuant to demand registration rights described below under “— Demand Registration Rights” beginning after February 7, 2009, subject to the requirement that from February 7, 2009 until February 7, 2010, no more than 1,401,822 shares of Thomas Weisel Partners common stock may be sold and from February 7, 2010 to February 7, 2011, no more than 1,401,822 shares may be sold (less the number of shares sold during the preceding one year period), which we refer to as the public offering limitation. In addition, if we register any securities for sale in an underwritten public offering, each Westwind shareholder would have “piggyback registration rights” that would provide each such shareholder the right to include covered shares consisting of Thomas Weisel Partners common stock in the registration, subject to specified exceptions. In addition to customary cutbacks as well as the public offering limitation set forth above, the Westwind shareholder would not be entitled to transfer more than twenty percent of his, her or its covered shares during the twelve month period following the closing date of the transaction.

Our Underwritten Offering Committee may, acting reasonably, approve requests by a Westwind shareholder to transfer covered shares to certain permitted transferees such as family members, family trusts or corporations and certain charitable organizations; provided that these transferees will be subject to the same transfer restrictions under the WW Equity Agreement.

In addition, upon the termination of a Westwind shareholder’s employment due to his or her death or disability, such Westwind shareholder or his or her heirs or estate will be permitted to sell covered shares in compliance with applicable securities laws, regardless of when such termination of employment occurred.

Notwithstanding the exceptions to transfer described above, transfer restrictions will not terminate with respect to covered shares that have been pledged to us as security in connection with the shareholder covenants described below until those shareholder covenants expire.

All transfer restrictions applicable to a Westwind shareholder under the WW Equity Agreement terminate upon a change in control of us.

Compliance with Securities Laws. In addition to the restrictions set forth above, Westwind shareholders will need to comply with applicable securities laws in connection with any transfer of Thomas Weisel Partners common stock or exchangeable shares covered by the WW Equity Agreement.

Dividends. To the extent dividends are paid on covered shares while the Westwind shareholder remains subject to the transfer restrictions of the WW Equity Agreement, the Westwind shareholder will be entitled to such dividends.

Voting. Each Westwind shareholder is entitled to full voting rights with respect to his or her covered shares.

Confidentiality. Each Westwind shareholder is required to protect and use “confidential information” in accordance with the restrictions placed by us on its use and disclosure.

135

Noncompetition. Each Westwind shareholder has agreed that during his or her employment period and during his or her applicable post-termination non-compete and non-solicit period, which is described below, he or she may not:

•

form, or acquire a 5% or greater ownership, voting or profit participation interest in, any competitive enterprise; or

•

associate with any competitive enterprise and in connection with such association engage in, or directly or indirectly manage or supervise personnel engaged in, any activity (i) which is similar or substantially related to any activity in which that shareholder was engaged, in whole or in part, at Thomas Weisel Partners, (ii) for which that shareholder had direct or indirect managerial or supervisory responsibility at Thomas Weisel Partners or (iii) which calls for the application of the same or similar specialized knowledge or skills as those utilized by that shareholder in his or her activities at Thomas Weisel Partners, at any time during the one-year period immediately prior to the date of termination (or, in the case of an action taken during the employment period, during the one-year period immediately prior to that action).

When we refer to a “competitive enterprise,” we are referring to any business enterprise that engages in, or owns or controls a significant interest in any entity that engages in, financial services such as investment banking, public or private finance, financial advisory services, private investing, merchant banking, asset or hedge fund management, securities brokerage, sales, lending, custody, clearance, settlement or trading.

A Westwind shareholder’s applicable post-termination non-compete and non-solicit period will range from 12 months to 36 months following the date the Westwind shareholder ceases to be employed by us (with each shareholder required to give 90 days’ notice of termination), with the exact length of the period determined by the relative seniority of the Westwind shareholder and his or her equity ownership interest in Westwind prior to the transaction, as well as the length of the period that has elapsed since the closing of the transaction.

Nonsolicitation. Each Westwind shareholder also has agreed that during his or her employment period and the applicable post-termination non-compete and non-solicit period, he or she may not, directly or indirectly, in any manner:

•

solicit any client with whom that Westwind shareholder worked, or whose identity became known to him or her in connection with his or her employment with Thomas Weisel Partners, to transact business with a competitive enterprise or reduce or refrain from doing any business with Thomas Weisel Partners;

•

interfere with or damage any relationship between Thomas Weisel Partners and any client or prospective client; or

•

solicit any of our employees to resign, apply for or accept employment with, any competitive enterprise.

Transfer of Client Relationships. Each Westwind shareholder is required, upon termination of his or her employment, to take all actions and do all things reasonably requested by us during a 90-day cooperation period to maintain for us the business, goodwill and business relationships with our clients with which he or she worked.

Liquidated Damages. In the case of any breach of the confidentiality, noncompetition or nonsolicitation provisions or the provisions related to the transfer of client relationships during the term of the agreement, the breaching Westwind shareholder will be liable for liquidated damages. The liquidated damages amount for each Westwind shareholder will be equal to 50% of the total amount of consideration paid to that Westwind shareholder in exchange for his, her or its Westwind shares, less any amount paid to us by that Westwind shareholder in connection with that shareholder’s indemnification obligation under the arrangement agreement, other than for certain excluded losses under the arrangement agreement. The liquidated damages obligation of

136

each Westwind shareholder generally is secured by Thomas Weisel Partners common stock and exchangeable shares representing 50% of the total amount of consideration received by that Westwind shareholder in respect of his or her Westwind shares in connection with the transaction.

Severance. The WW Equity Agreement provides that if we terminate a Westwind shareholder without cause, as defined in the WW Equity Agreement, we would be obligated to pay the shareholder, in a lump sum, an amount equal to the excess, if any, of (A) the product of (x) the amount of base salary and bonus paid to that shareholder for the twelve months ending before notice of termination and (y) the number of years comprising the then-applicable post-termination and non-compete and non-solicit period and (z) 0.5, over (B) any severance amounts to which the shareholder is otherwise entitled either pursuant to an employment agreement, Company policy or applicable law.

Demand Registration Rights. The WW Equity Agreement provides for demand registration rights. Under those rights, at any time following February 7, 2009, a Westwind shareholder party to the agreement has been entitled to require us to effect the registration of all or a portion of that shareholder’s registrable securities (generally shares of Thomas Weisel Partners common stock issued to a Westwind shareholder in exchange for his, her or its Westwind shares (including shares issuable upon exchange of exchangeable shares) but not including those shares of Thomas Weisel Partners common stock that have been sold pursuant to an effective registration statement or that have been sold pursuant to Rules 145 or 144 under the Securities Act or that may be sold pursuant to Rule 145(d)(3) or Rule 144(k)). We will not be obligated to effect a demand registration unless, among other things, the total number of shares of registrable securities requested to be included in the demand registration is equal to or greater than 15% of the total number of shares of Thomas Weisel Partners common stock (including shares deliverable upon exchange of exchangeable shares) issued in connection with the transaction.

We are not required to effect more than three registrations in response to these demand registration rights under the agreement in any twelve month period. In addition, we are not obligated to effect a demand registration within 120 days of a piggyback registration effected pursuant to the agreement or a demand registration effected pursuant to our partners’ equity agreement. We may postpone the filing of a registration statement for up to 90 days if our board of directors determines that it is not in our best interest to disclose any material non-public information or a significant business opportunity or if, prior to receiving a demand registration request, we have determined to proceed with a public offering. We generally will pay expenses, except for underwriters’ discounts and commissions, incurred in connection with the registration rights under the WW Equity Agreement.

Only those shareholders that (x) continue to be actively engaged in the business of Thomas Weisel Partners, (y) have suffered a termination of employment by Thomas Weisel Partners without cause or resulting from a disability or (z) are permitted transferees will be entitled to registration rights.

Each shareholder receiving exchangeable shares has agreed or will agree that it may not exercise its exchange, redemption or similar rights with respect to its exchangeable shares at any time when the exchangeable share registration statement is not effective, provided that we must maintain the effectiveness of the exchangeable share registration statement for a minimum of at least 180 days in each annual period beginning February 7, 2009.

Term and Amendment. The WW Equity Agreement will be in effect until the later of the fifth anniversary of the closing of the transaction and the date that is six months following the date on which all of the exchangeable shares have been exchanged for Thomas Weisel Partners common stock. A Westwind shareholder seeking a waiver from the WW Equity Agreement generally requires our consent, and the WW Equity Agreement may be amended only with approval of our board of directors.

Westwind Pledge Agreements

Each of the Westwind shareholders that received exchangeable shares or shares of Thomas Weisel Partners common stock in the transaction has entered into a pledge agreement with us that will secure the liquidated damages provisions in the WW Equity Agreement entered into in connection with the Westwind transaction and

137

the indemnification obligations under the arrangement agreement by a pledge of an amount of shares of Thomas Weisel Partners common stock or exchangeable shares equal to 50% of the total value of the consideration received by that shareholder in exchange for his or her Westwind common shares and Class A common shares. These pledges of Thomas Weisel Partners common stock and/or exchangeable shares will terminate on the earliest to occur of:

•

the death of the relevant shareholder;

•

the expiration of the applicable non-compete and non-solicit period described above;

•

payment in cash or other satisfaction by the shareholder of all liquidated damages; or

•

February 7, 2011;

provided, that no shares will be released from the pledge before the first anniversary of the closing of the transaction.

The liquidated damages provisions in the WW Equity Agreement are in addition to the forfeiture of any equity-based awards that may occur as a result of the breach of any non-competition or non-solicitation provisions contained in those awards. The liquidated damages and pledge arrangements do not preclude us from seeking any injunctive relief to which we may be entitled for a breach of the confidentiality, non-competition, non-solicitation or transfer of client relationship provisions in the case of a willful or intentional breach that causes material harm to us.

Compensation Discussion and Analysis

This compensation discussion and analysis relates to the compensation paid to or earned by the executive officers listed below for their 2009 service. These executive officers consist of our principal executive officer, our principal financial officer and our other three most highly compensated executive officers who were serving as executive officers on December 31, 2009. In addition, our former Chief Financial Officer, Shaugn Stanley, who was employed with us as Chief Financial Officer during part of 2009, is also included. As noted above, these officers are collectively referred to as our “named executive officers” in this proxy statement.

•

Thomas W. Weisel, our Chairman and Chief Executive Officer

•

Lionel F. Conacher, our President and Chief Operating Officer

•

Ryan Stroub, our Chief Financial Officer

•

Shaugn Stanley, our Chief Administrative Officer and former Chief Financial Officer

•

Bradford Raymond, our Co-Head of Investment Banking

•

Anthony Stais, our Head of Trading

This compensation discussion and analysis describes all of the material elements of our compensation of our named executive officers for their 2009 services and includes, as it relates to our named executive officers, a discussion of (i) the objectives of our compensation policies and practices and what they are designed to reward, (ii) each element of 2009 compensation and why we utilize that element, (iii) how we determine the amount of each compensation element and (iv) how each compensation element and our decisions regarding that element fit into our overall compensation objectives and affect decisions regarding other elements.

What are the objectives of our compensation policies and practices for our named executive officers? What are they designed to reward?

Our compensation policies and practices for named executive officers are intended to:

•

Incentivize and reward the achievement of financial and operational performance, while taking into account the risks associated therewith;

•

Align the interests of our named executive officers and those of our shareholders; and

•

Assist in retaining the employment of our named executive officers.

138

In addition, where applicable, our compensation practices take into account factors other than financial returns and risks, such as adherence to our Code of Conduct and Ethics and other employee policies.

What are the elements of 2009 compensation for our named executive officers? Why do we use these elements?

In 2009 there were five elements of compensation for our named executive officers:

•

Base Salary

•

Year-End Cash Bonus (paid in January 2010)

•

Annual Equity Incentive Plan Award (granted in February 2009)

•

Mid-Year Cash Bonus (paid in August 2009)

•

Mid-Year Equity Incentive Plan Award (granted in August 2009)

•

Other Awards and Amounts

Base Salary. In 2009 all of our named executive officers received an annual salary payable in equal installments on a semi-monthly basis.

Year-End Cash Bonus. In January 2010 we paid our named executive officers a year-end cash bonus with respect to their 2009 service. Our Compensation Committee, at its sole discretion, determined the amount of each named executive officer’s year-end cash bonus at the beginning of 2010 based on 2009 performance. Pursuant to the terms of his employment agreement, Mr. Conacher is guaranteed a minimum bonus of $2.4 million cash and equity for 2009. The bonus amounts that are discretionary may be as low as zero or instead be a significant amount.

Annual Equity Incentive Plan Award. In February 2009, at the same time we paid our 2008 year-end cash bonuses, we made stock awards in the form of restricted stock units granted pursuant to our Equity Incentive Plan. These stock awards will be earned over a three-year service period that began on February 27, 2009 and vest in three equal installments on the first, second and third anniversaries of the grant date. These Equity Incentive Plan awards are intended to align the recipients’ interests with those of our shareholders and to act as a device for retaining the recipients within our employment during the vesting period. In 2007, 2008 and 2009, we determined to use restricted stock units as the form of equity award to grant to named executive officers because we believe that restricted stock units are an effective way to align the interests of our named executive officers with our shareholders. The economic impact of a change in our stock price is the same for both a holder of a restricted stock unit and a holder of a share of Thomas Weisel Partners common stock. By contrast, the economic impact of a change in our stock price will be different for the holder of an option when the stock price is below the exercise price of the option because a change in the stock price will not affect the intrinsic value of the option. We also believe restricted stock units encourage an appropriate long-term focus among our named executive officers because the value of restricted stock units increases if the value of Thomas Weisel Partners’ stock rises during the term of the award. We believe these considerations also explain why restricted stock units are the form of equity award most commonly utilized by firms in our industry.

Mid-Year Cash Bonus. In August 2009, we made mid-year cash bonuses to certain of our officers and employees, including Mr. Conacher pursuant to the terms of his employment agreement. The mid-year bonus payment made to Mr. Conacher is in partial satisfaction of his guaranteed 2009 bonus. The mid-year bonuses are generally paid to our Canadian employees and were implemented, in part, to facilitate the transition to Thomas Weisel Partners’ compensation regime of former Westwind employees, who previously received quarterly bonus awards under Westwind’s compensation regime.

Mid-Year Equity Incentive Plan Award. In August 2009, we made mid-year equity incentive plan award in the form of restricted stock units granted pursuant to our Equity Incentive Plan to certain of our officers and employees, including Mr. Conacher pursuant to the terms of his employment agreement. The mid-year bonus payment made to Mr. Conacher is in partial satisfaction of his guaranteed 2009 bonus. The mid-year bonuses

139

were implemented, in part, to facilitate the transition to Thomas Weisel Partners’ compensation regime of former Westwind employees, who previously received quarterly bonus awards under Westwind’s compensation regime. These awards will be earned over a three-year service period that began in August 2009 and vest in three equal installments on the first, second and third anniversaries of the grant date.

Other Awards and Amounts. We provided benefits to our named executive officers, which included paying certain term life insurance premiums, medical, dental and vision plan premiums and long-term/short-term disability insurance premiums.

In addition, we have in the past, and may in the future, grant performance based incentive awards to certain of our employees including our named executive officers. These performance based awards are typically tied to the attainment of one or more performance metrics. However, the establishment of performance based awards for named executive officers does not typically preclude the pay of discretionary compensation, such as year-end cash bonuses and year-end equity incentive plan awards to these individuals. Accordingly, the performance metrics identified in any performance award are not typically used by the Compensation Committee in determining the discretionary component of a named executive officers’ compensation.

How do we determine the amount of each compensation element for our named executive officers?

The chart below illustrates the percentage of aggregate compensation (excluding the cost of life insurance, medical and disability benefits) paid to our named executive officers for 2009 that is non-discretionary (e.g., base salaries and guaranteed amounts) as opposed to discretionary (e.g., year-end cash bonus and equity incentive plan awards).

2009 Aggregate Compensation to Named Executive Officers

Discretionary vs. Non-Discretionary

LOGO

As a general matter, Thomas Weisel Partners believes that the annual incentive award, which consists of a year-end cash bonus and an annual equity incentive award, is the most important element of its named executive officers’ overall compensation. Thomas Weisel Partners’ Compensation Committee apportions the annual incentive award between the year-end cash bonus and an annual equity incentive award to further Thomas Weisel Partners’ stated compensation objectives.

Base Salary. Each of our named executive officers, with the exception of Mr. Ryan Stroub, is a party to an employment agreement with us specifying a $200,000 annual base salary. Mr. Stroub receives a $300,000 annual base salary, which reflects a determination of Thomas Weisel Partners to emphasize non-discretionary compensation in the case of individuals in charge of financial reporting, consistent with Thomas Weisel Partners’

140

approach to ensuring incentives are properly aligned with the role and as such encourage the independence of the financial reporting function from Thomas Weisel Partners’ business operations consistent with our view of best market compensation practices. In connection with our cost cutting measures in 2009, the base salaries for all of our employees at the level of vice president and above, which includes each of our named executive officers, were reduced by 10%.

Accordingly, the base salary in 2009 for each of our named executive officers, other than Mr. Stroub, was reduced to $180,000, and Mr. Stroub’s base salary was reduced to $270,000. Further information regarding these employment agreements is set forth above under “—Executive Officer Employment and Other Agreements.” Our intention with respect to our named executive officers, other than our Chief Financial Officer, is that base salary should, in a normal economic environment, constitute only a moderate portion of their overall compensation, while discretionary bonuses and Equity Incentive Plan awards should, in a normal economic environment, constitute the most significant portion of annual compensation. With respect to our Chief Financial Officer, the salary represents a more significant portion of pay and we would expect to provide appropriate discretionary bonuses commensurate with the role and performance.

Year-End Cash Bonus and Annual Equity Incentive Award. As a general matter, Thomas Weisel Partners believes that the annual incentive award, which consists of a year-end cash bonus and an annual equity incentive award, is the most important element of its named executive officers’ overall compensation. Thomas Weisel Partners’ Compensation Committee apportions the annual incentive award between the year-end cash bonus and an annual equity incentive award to further Thomas Weisel Partners’ stated compensation objectives.

In determining the size of a named executive officer’s total annual incentive award, the Compensation Committee takes into consideration several factors, including Thomas Weisel Partners’ overall performance, that individual’s identified contribution to Thomas Weisel Partners, the overall performance of the business line or function managed by that individual and compensation levels for comparable executives at selected peer companies. In addition, the Compensation Committee generally reviews data for selected peer companies regarding overall compensation and the cash/equity split obtained from publicly available sources, as well as data provided to the Compensation Committee by compensation consultants. However, the Compensation Committee does not use such peer information and market data to benchmark its compensation and equity split decisions, rather such information is used by Thomas Weisel Partners as a “market check” on the Compensation Committee’s compensation and equity split decisions.

For each of Thomas Weisel Partners’ named executive officers, other than the Chief Executive Officer, the identified contribution to Thomas Weisel Partners consists of the Compensation Committee’s, the Chief Executive Officer’s and/or the Chief Operating Officer’s evaluation of (a) that person’s participation as a member of Thomas Weisel Partners’ executive committee and involvement in the day-to-day management of Thomas Weisel Partners, (b) that person’s contribution as a manager of a specific business line and (c) incremental revenue produced by that person as a member of Thomas Weisel Partners’ investment banking, brokerage or wealth management businesses. Historically, several of Thomas Weisel Partners’ named executive officers have been directly involved in revenue generating activities at Thomas Weisel Partners, either in Thomas Weisel Partners’ investment banking, brokerage or wealth management businesses. For instance, of our 2009 named executive officers, Mr. Raymond, Co-Head of Investment Banking, is actively involved in producing revenues as a member of Thomas Weisel Partners’ investment banking business and Mr. Stais, Head of Trading, is actively involved in producing revenues as a member of Thomas Weisel Partners’ brokerage business. Thomas Weisel Partners has not used a specific formula based on production levels to generate compensation levels, but the department heads that are also producers have revenue targets that a portion of their compensation is determined by, however this is only one determinant of the overall compensation.

For our Chief Executive Officer, during 2009 our Compensation Committee together with management, developed a set of financial and non-financial metrics to utilize as one factor in evaluating his 2009 performance, although specific targets were not established in advance. The financial metrics included: net revenue, pre-tax

141

income, shareholder return, return on equity, earnings per share and market share and other investment banking league table metrics. The non-financial metrics included: strategic goals, resource management, growth and maintenance of our brand, vision and culture and certain tactical matters. Finally, the history of Thomas Weisel Partners as a partnership and the integrated nature of all of our business activities were taken into account.

In addition to the foregoing, the Compensation Committee also takes other factors into consideration in determining the annual incentive award. In general, we manage our aggregate compensation and benefits expense in relation to our net revenues, our available cash and the need to retain key employees. In doing so, we generally attempt to maintain certain limits and avoid crossing other thresholds. For instance, we seek to maintain a ratio of compensation and benefits expense to net revenue of 60% or less, but have found the need to pay out at higher ratios at lower revenue levels. This allows us to provide competitive compensation for our employees without jeopardizing our ongoing operations. In addition, we strive to ensure that our key employees are compensated at rates no lower than the 50th percentile of their peers at our competitor firms. We believe the success of our business is based largely on the quality of our employees and we continually monitor the market for their services and attempt to offer competitive compensation. We believe it is in our shareholders’ best interest to attempt to minimize employee turnover as a result of paying below market compensation. By striving to keep our payscale for our key employees within the range paid by our direct competitors, we believe we can retain our key employees. Finally, in considering the amount and form of compensation paid to our employees, we strive to maintain sufficient available cash to maintain operations for at least 12 months to ensure our ongoing operations.

In 2009, our aggregate compensation and benefits expense (excluding expense relating to equity awards made in connection with our initial public offering) was 68% of our net revenues (excluding investment gains and losses attributable to investments in partnerships and other securities). The Compensation Committee determined the amount of year-end cash bonus for 2009 in early 2010. The Compensation Committee considered the factors described above and took into account the aggregate amount of compensation and benefits expense that had already been determined during the course of the year. These pre-determined compensation expenses include:

•

base salary amounts paid during 2009;

•

formula- and commission-based amounts in respect of performance during 2009, including target amounts payable under any performance-based cash and stock awards;

•

guaranteed compensation amounts in respect of 2009 that were established in connection with hiring or retaining specified individuals;

•

discretionary compensation amounts paid prior to the end of 2009;

•

equity award expense for equity awards granted prior to the end of 2009; and

•

benefits expense.

With respect to our named executive officers, in 2009 the pre-determined compensation expense consisted of (i) base salary expense, (ii) equity award expense for equity awards granted prior to the end of 2009, (iii) benefits expense; and (iv) certain guaranteed bonus expenses payable to Mr. Conacher.

After taking into account the aggregate amounts that had already been determined, the aggregate amount available for discretionary 2009 year-end cash bonus payments for all officers and employees, including our named executive officers, was approximately $28.0 million.

In apportioning the annual incentive award between a cash bonus and equity payment to Thomas Weisel Partners’ named executive officers, the most significant factor considered by the Compensation Committee is Thomas Weisel Partners’ effort to balance the competing demands of rewarding performance while retaining and incentivizing Thomas Weisel Partners’ named executive officers. As a general matter, the Compensation Committee attempts to maintain approximately the same split between cash and equity for each of the named executive officers. However, the Compensation Committee will take into account other factors that may result in

142

proportionally more cash or more equity for a named executive officer including the named executive officer’s compensation in prior years, the cash and equity split in those prior years, that individual’s equity ownership in Thomas Weisel Partners and any other circumstances that would otherwise affect the ability of Thomas Weisel Partners to retain that individual. For instance, if a certain named executive officer had a relatively small equity interest in Thomas Weisel Partners, the Compensation Committee may determine that the individual’s annual incentive award should include more equity. Alternatively, if the Compensation Committee determines that an individual should be immediately rewarded for financial or operational performance, or if the market circumstances require a higher cash amount in order to retain such individual, the Compensation Committee may consider whether the annual incentive award should include proportionally more cash.

With respect to the actual amounts paid in 2009 as year-end cash bonus, the variance in cash bonus paid to our named executive officers resulted from a number of factors considered by the Compensation Committee, including the following:

•

Thomas Weisel Partners’ Chief Executive Officer, Mr. Thomas Weisel, elected not to receive a cash year-end bonus given Thomas Weisel Partners’ operating loss and our stated goal of reducing our cost structure while positioning Thomas Weisel Partners for when the markets eventually turn positive;

•

under the terms of Thomas Weisel Partners’ President and Chief Operating Officer’s employment contract, Mr. Lionel Conacher was entitled to a guaranteed bonus of $2.4 million, of which $1,444,000 was paid in cash and the remainder in equity awards;

•

Thomas Weisel Partners’ former Chief Financial Officer, Mr. Shaugn Stanley, resigned from the position of Chief Financial Officer in May 2009 and subsequently became Thomas Weisel Partners’ Chief Administrative Officer;

•

Thomas Weisel Partners’ current Chief Financial Officer, Mr. Ryan Stroub, was promoted to the position of Chief Financial Officer in May 2009 and served the remainder of the year in such role;

•

Thomas Weisel Partners’ Co-Head of Investment Banking, Mr. Bradford Raymond was actively managing several client relationships and was the principal investment banker on a number of key banking transactions, and the overall performance of our investment banking business, which is co-managed by Mr. Raymond; and

•

Thomas Weisel Partners’ Head of Trading, Mr. Anthony Stais has personal production as a trader and the overall performance of Thomas Weisel Partners’ brokerage business, which is directly managed by Mr. Stais.

Mid-Year Cash Bonus. The factors utilized by the Compensation Committee in determining mid-year cash bonuses are similar to those described above under “Year-End Cash Bonus.” In general, the mid-year cash bonus is given to our Canadian employees, in part, to assist in the transition of former Westwind employees, including Mr. Conacher, to Thomas Weisel Partners’ compensation regime. Westwind had historically paid quarterly bonuses while we have historically relied on year-end bonuses to compensate our employees. In 2009, Mr. Conacher received $660,000 as his mid-year cash bonus. No other named executive officer received a mid-year cash bonus.

Mid-Year Equity Incentive Plan Award. The factors utilized by the Compensation Committee in determining mid-year equity incentive plan awards are similar to those described above under “Annual Equity Incentive Plan Awards.” In general, the mid-year equity incentive plan award is given to our Canadian employees, in part, to assist in the transition of former Westwind employees, including Mr. Conacher, to Thomas Weisel Partners’ compensation regime. Westwind had historically paid quarterly bonuses while we have historically relied on year-end bonuses to compensate our employees. In 2009, Mr. Conacher received $540,000 of equity awards as his mid-year equity incentive plan award. No other named executive officer received a mid-year equity incentive award.

Other Awards and Amounts. We have historically provided a benefit to certain executive officers, including our named executive officers, of paying certain term life insurance premiums, medical, dental and vision plan

143

premiums and long-term/short-term disability insurance premiums. In 2009 we continued this practice, as we believe that these are customary benefits provided to senior officers of companies like ours and these aspects of compensation are not material in relation to overall compensation paid to named executive officers.

How does each compensation element and our decisions regarding that element fit into our overall compensation objectives and affect decisions regarding other elements?

As stated above, our compensation policies and practices for named executive officers are intended to:

•

Incentivize and reward the achievement of financial and operational performance, while taking into account the risks associated therewith;

•

Align the interests of our named executive officers and those of our shareholders; and

•

Assist in retaining the employment of our named executive officers.

We believe each element of 2009 compensation complements and balances the other elements in the context of our overall compensation objectives. While some elements address our stated compensation objectives directly, others do so to varying degree. As a Company, we continually balance the form and amount of each element of overall compensation since decisions made with respect to one element of compensation have an impact on the other elements. For example, the decision to pay compensation in the form of one of our compensation elements might reduce the amount available to be paid under other compensation elements and, therefore, our decisions with respect to any one compensation element potentially affect decisions regarding other compensation elements.

Base Salary. We believe that the purpose of a base salary is to provide a set amount of cash compensation for each named executive officer that is not generally variable in nature and is competitive with salaries paid by peer companies. We also believe that in normal economic conditions, most of the total annual compensation paid to named executive officers, other than our Chief Financial Officer, should be in the form of year-end cash bonuses and annual equity incentive plan awards. While base salary does not generally incentivize or reward our named executive officers for specific financial or operational performance, we believe that maintaining a competitive base salary is a necessary component of compensation that provides a stable cash flow and does provide a retentive effect. We believe shareholders have an interest in retaining high quality employees and base salaries such as the ones paid to our named executive officers are commensurate with their positions and competitive with our peers.

Year-End Bonus and Annual Equity Incentive Plan Award. We believe that the year-end bonus and the annual equity incentive plan award are the two most important elements of our named executive officers’ overall compensation and that the two must be carefully balanced to meet our stated compensation objectives. As a general matter, our annual incentive award consists of a year-end cash bonus and an equity award. In apportioning the annual incentive award between these two, the most significant factor considered by the Compensation Committee is Thomas Weisel Partners’ effort to balance the competing demands of rewarding performance, retaining and incentivizing employees, maintaining Thomas Weisel Partners’ cash position and managing the dilution of Thomas Weisel Partners’ stock. The annual incentive award will be weighted more towards cash to the extent Thomas Weisel Partners is seeking to immediately reward performance or manage dilution of Thomas Weisel Partners’ stock. The annual incentive award will be weighted more towards equity to the extent Thomas Weisel Partners is seeking to maintain its cash position, retain key employees over time and/or align incentives of key employees with shareholders.

We believe that year-end cash bonuses reward and incentivize achievement and performance by our named executive officers because the individual performance and contributions of each individual are specifically factored into the determination of the amount of their year-end cash bonus. Additionally, a cash payment minimizes dilution of existing shareholders, thereby aligning investors with the named executive officers. Finally, because our year-end cash bonuses are paid only to employees employed with Thomas Weisel Partners on the payment date, the year-end cash bonus provides a retentive effect.

144

Likewise, the annual equity incentive plan award rewards and incentivizes achievement and performance by our named executive officers because the individual’s performance and direct contributions are taken into account in determining the size of the award. Additionally, the equity awards provide a retentive effect since awards vest over 3 or 4 year periods. Our named executive officers must remain employed by Thomas Weisel Partners in order to vest their equity awards. Equity awards also minimizes employee turnover, which we believe is in the best interest of our investors.

Mid-Year Cash Bonus and Mid-Year Equity Incentive Plan Award. As described above, the mid-year cash bonus and the mid-year equity incentive plan award are given primarily to our Canadian employees. Our Compensation Committee considers the same factors detailed in our year-end cash bonus and annual equity incentive plan award discussions. As described above, in general mid-year bonuses are a transitional accommodation to former Westwind employees as they transition to our compensation regime.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

In the opinion of Sullivan & Cromwell LLP and in the opinion of Bryan Cave LLP, the following section describes the anticipated material United States federal income tax considerations of the merger generally applicable to Thomas Weisel Partners stockholders. These opinions and the following discussion are based on and subject to the Internal Revenue Code of 1986, as amended, or the Code, the regulations promulgated under the Code, existing interpretations and court decisions, all of which are subject to change, possibly with retroactive effect. Any such change could affect the continuing validity of the discussion. This discussion applies to you only if you hold your Thomas Weisel Partners common stock as capital assets for tax purposes. This discussion does not address all aspects of United States federal income taxation that may be important to you in light of your particular circumstances or if you are subject to special rules, such as rules relating to:

•

stockholders who are not United States persons;

•

financial institutions;

•

tax-exempt organizations;

•

insurance companies;

•

dealers in securities or currencies;

•

traders in securities that elect to use a mark-to-market method of accounting;

•

stockholders who acquired their shares of Thomas Weisel Partners common stock pursuant to the exercise of employee stock options or otherwise acquired shares as compensation;

•

stockholders who hold their shares of Thomas Weisel Partners common stock as part of a hedge, straddle or other risk reduction, constructive sale or conversion transaction; and

•

holders of exchangeable shares of TWP Acquisition Company (Canada), Inc. or shares of special voting preferred stock of Thomas Weisel Partners.

It is intended that the merger will qualify as a reorganization under the provisions of Section 368(a) of the Code. Stifel’s and Thomas Weisel Partners’ obligations to complete the merger are conditioned on, among other things, Stifel’s receipt of an opinion from Bryan Cave LLP and Thomas Weisel Partners’ receipt of an opinion from Sullivan & Cromwell LLP, each dated the closing date, to the effect that, on the basis of the facts, representations and assumptions set forth in the opinions, the merger will be treated for federal income tax purposes as a reorganization within the meaning of Section 368(a) of the Code and that each of Stifel, Merger Sub and Thomas Weisel Partners will be a party to that reorganization within the meaning of Section 368(b) of the Code. The following discussion assumes that the merger will be treated accordingly.

The opinions of counsel described above will be based on the then-existing law, will assume the absence of changes in existing facts, will rely on customary assumptions and may rely on representations contained in certificates executed by officers of Stifel, Merger Sub and Thomas Weisel Partners. The opinions neither bind the Internal Revenue Service, or the IRS, nor preclude the IRS from adopting a contrary position, and it is possible that the IRS may successfully assert a contrary position in litigation or other proceedings. Neither Stifel nor Thomas Weisel Partners intends to obtain a ruling from the IRS with respect to the tax consequences of the merger.

Tax Implications to Thomas Weisel Partners’ Stockholders

If you are a holder of Thomas Weisel Partners common stock, your exchange of Thomas Weisel Partners common stock for Stifel common stock will have the following consequences to you:

•

Except as discussed below with respect to cash received in lieu of fractional shares, you will not recognize gain or loss for United States federal income tax purposes when you exchange your Thomas Weisel Partners common stock solely for Stifel common stock pursuant to the merger.

146

•

The aggregate tax basis of the Stifel common stock you receive as a result of the merger will be the same as your aggregate tax basis in Thomas Weisel Partners common stock you surrender in exchange for the Stifel common stock, less any basis attributable to fractional share interests in Stifel common stock for which cash is received.

•

The holding period of the Stifel common stock you receive as a result of the exchange will include the holding period of Thomas Weisel Partners common stock you exchange in the merger.

If you receive cash in the merger instead of a fractional share interest in Stifel common stock, you will be treated as having received the cash in redemption of the fractional share interest. If the redemption is “not essentially equivalent to a dividend” under the relevant Code provision, after giving effect to certain constructive ownership rules, you would recognize capital gain or loss on the deemed redemption in an amount equal to the difference between the amount of cash received and your adjusted tax basis allocable to such fractional share. Otherwise, the cash payment may be taxable to you as a dividend. Any capital gain or loss will be long-term capital gain or loss if you have held your shares of Thomas Weisel Partners common stock for more than one year at the time the merger is completed. Long-term capital gain of a non-corporate U.S. stockholder is generally subject to a maximum rate of 15% assuming the merger closes in 2010. The deductibility of capital losses is subject to limitations. Because the possibility of dividend treatment depends primarily upon your particular circumstances, including the application of certain constructive ownership rules, you should consult your own tax advisor regarding the potential tax consequences of the merger to you.

Backup Withholding and Information Reporting. Payments of cash to you instead of a fractional share of Stifel common stock may, under certain circumstances, be subject to information reporting and backup withholding unless you provide proof of an applicable exemption or furnish your taxpayer identification number, and otherwise comply will applicable requirements of the backup withholding rules. Any amounts withheld from payments to you under the backup withholding rules are not an additional tax and will be allowed as a refund or credit against your United States federal income tax liability, provided the required information is furnished to the Internal Revenue Service.

The foregoing discussion is not intended to be a complete analysis or description of all potential United States federal income tax consequences of the merger. In addition, the discussion does not address tax consequences which may vary with, or are contingent on, your individual circumstances. Moreover, the discussion does not address any non-income tax or any foreign, state or local tax consequences of the merger. Accordingly, you are strongly encouraged to consult with your own tax advisor as to the tax consequences of the merger in your particular circumstances, including the applicability and effect of the alternative minimum tax and any state, local or foreign and other tax laws and of changes in those laws.

OTHER MATTERS

Other Business

The Thomas Weisel Partners board of directors does not currently intend to bring any other business before the Annual Meeting and, to the knowledge of the Thomas Weisel Partners board of directors, no other matters other than those indicated above are to be brought before the Annual Meeting. If, however, any other matter properly comes before the Annual Meeting, the proxy holders will, in their discretion, vote on it in accordance with their own best judgment.

Stockholder Proposals for 2011 Annual Meeting of Stockholders

Stockholders who, in accordance with the SEC’s Rule 14a-8, wish to present proposals for inclusion in the proxy materials to be distributed by us in connection with our 2011 Annual Meeting of Stockholders must have submitted their proposals to our Secretary on or before January 24, 2011. As the rules of the SEC make clear, simply submitting a proposal does not guarantee its inclusion.

If the merger is consummated, there will be no annual meeting of Thomas Weisel Partners stockholders in 2011. If the merger is not consummated, Thomas Weisel Partners will hold a 2011 Annual Meeting of Stockholders.

In accordance with Section 1.11(b) of our bylaws, for a matter not included in our proxy materials to be properly brought before the 2011 Annual Meeting of Stockholders, a stockholder’s notice of the matter the stockholder wishes to present must be delivered to our Secretary & General Counsel at One Montgomery Street, 37th Floor, San Francisco, California 94104 as follows:

(i) If the 2011 Annual Meeting is scheduled to take place within 30 days before or after the first anniversary date of the Annual Meeting, such notice shall be delivered not less than 90 days nor more than 120 days prior to the first anniversary date of the Annual Meeting;

(ii) If, and only if, the 2011 Annual Meeting is not scheduled to take place within 30 days before or after the first anniversary date of the Annual Meeting, such notice shall be delivered before the close of business on the later of (a) the date ninety days prior to the date of the 2011 Annual Meeting or (b) the tenth day following the date on which the date for the 2011 Annual Meeting is first publicly announced or disclosed.

Assuming that the 2011 Annual Meeting occurs within 30 days before or after the first anniversary date of the Annual Meeting, any such notice given by or on behalf of a stockholder pursuant to these provisions of our bylaws (and not pursuant to SEC’s Rule 14a-8) must be received no earlier than February 22, 2011 and no later than March 24, 2011.

Stockholders Sharing an Address

The SEC has adopted rules that permit companies and intermediaries (such as banks and brokers) to satisfy the delivery requirements for proxy statements with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders.

ARTICLE 2

THE MERGER

Section 2.01 The Merger.

(a) At the Effective Time, Merger Subsidiary shall be merged (the “Merger”) with and into the Company in accordance with Delaware Law, whereupon the separate existence of Merger Subsidiary shall cease, and the Company shall be the surviving corporation (the “Surviving Corporation”).

A-7

(b) Subject to the provisions of Article 10, the closing of the Merger (the “Closing”) shall take place in St. Louis, Missouri at the offices of Bryan Cave LLP, 211 North Broadway, Suite 3600, St. Louis, Missouri 63102 as soon as possible, but in any event no later than two Business Days after the date the conditions set forth in Article 10 (other than conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or, to the extent permissible, waiver of those conditions at the Closing) have been satisfied or, to the extent permissible, waived by the party or parties entitled to the benefit of such conditions, or at such other place, at such other time or on such other date as Parent and the Company may mutually agree (the “Closing Date”). Notwithstanding the foregoing, either Party may, at its option, if the Closing would otherwise occur within ten (10) days before the last Business Day of a calendar month, defer the Closing to the final Business Day of such month; and the Parties will make all closing deliveries contemplated herein into escrow and will each deliver to the other a certificate signed by a duly authorized executive officer of such Party confirming on behalf of each such Party and its Affiliates that all conditions precedent to the obligations to consummate the transactions contemplated by this Agreement have been satisfied or waived and that the Parties will have irrevocably committed to completing the transaction on the final Business Day of such calendar month.

(c) Upon the Closing, the Company and Merger Subsidiary shall file a certificate of merger with the Delaware Secretary of State and make all other filings or recordings required by Delaware Law in connection with the Merger. The Merger shall become effective at such time (the “Effective Time”) as the certificate of merger is duly filed with the Delaware Secretary of State (or at such later time as permitted by Delaware Law as Parent and the Company shall agree and shall be specified in the certificate of merger).

(d) From and after the Effective Time, the Surviving Corporation shall possess all the properties, rights, powers, privileges and franchises and be subject to all of the obligations, liabilities, restrictions and disabilities of the Company and Merger Subsidiary, all as provided under Delaware Law.

ARTICLE 3

CONVERSION OF THE COMMON STOCK; EXCHANGE OF CERTIFICATES

Section 3.01 Effect on Capital Stock. At the Effective Time, as a result of the Merger and without any action on the part of the Company, Merger Subsidiary, Parent or any holder of any shares of the capital stock of the Company, Merger Subsidiary or Parent, the following shall occur:

(a) Each share of Company Common Stock (each, a “Company Share”, and together, the “Company Shares”) issued and outstanding immediately prior to the Effective Time (other than shares of Company Common Stock that are owned by Parent or by the Company or any direct or indirect wholly-owned Subsidiary of the Company and in each case not held on behalf of Third Parties (each an “Excluded Company Share”, and collectively, “Excluded Company Shares”)) shall be converted into the right to receive and shall become exchangeable for 0.1364 (such ratio, the “Exchange Ratio”) shares of common stock, par value $0.15 per share, of Parent (“Parent Common Stock”) (the “Merger Consideration”).

At the Effective Time, all Company Shares shall no longer be outstanding, shall be cancelled and retired and shall cease to exist, and (i) each certificate (a “Certificate”) formerly representing any of such Company Shares (other than Excluded Company Shares) and (ii) each uncertificated Company Share (an “Uncertificated Company Share”) registered to a holder on the stock transfer books of the Company (other than Excluded Company Shares), shall thereafter represent only the right to receive the Merger Consideration and the right, if any, to receive pursuant to Section 3.02(g) cash in lieu of fractional shares otherwise receivable pursuant to this Section 3.01(a) and any distributions or dividends pursuant to Section 3.02(f), in each case without interest.

(b) Each Company Share that is owned by Parent or by the Company or any direct or indirect wholly-owned Subsidiary of the Company and, in each case, not held on behalf of Third Parties, shall, by virtue of the Merger and without any action on the part of the holder thereof, cease to be outstanding, shall be cancelled and retired without payment of any consideration therefor and shall cease to exist.

A-8

(c) In the event the holders of the Company Exchangeable Shares approve the Exchangeable Share Amendment, (i) the share of Company Special Voting Preferred Stock issued and outstanding immediately prior to the Effective Time shall be converted into the one fully paid and nonasseable share of Parent Special Voting Preferred Stock (the “Parent Preferred Stock Consideration”), which Parent Special Voting Preferred Stock shall have terms that are identical to the Company Special Voting Preferred Stock (except that the issuer thereof shall be Parent rather than the Company and the voting rights described therein shall apply to Parent Common Stock rather than to Company Common Stock); and (ii) as of the Effective Time, such share of Company Special Voting Preferred Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and the certificate representing such Company Special Voting Preferred Stock shall thereafter represent only the right to receive the Parent Preferred Stock Consideration.

(d) Each share of common stock, par value $0.01 per share, of the Merger Subsidiary outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation, with the same rights, powers and privileges as the shares so converted, and which share shall constitute all of the issued and outstanding shares of stock of the Surviving Corporation.

Section 3.02 Surrender and Payment.

(a) Prior to the Effective Time, Parent shall appoint (subject to the Company’s prior approval not to be unreasonably withheld or delayed) a commercial bank or trust company (the “Exchange Agent”) for the purpose of exchanging Certificates or Uncertificated Company Shares for the Merger Consideration. As of the Effective Time, Parent shall deposit with the Exchange Agent, for the benefit of the holders of Company Shares, for exchange in accordance with this Section through the Exchange Agent, securities representing shares of Parent Common Stock issuable and payable pursuant to Section 3.01 in exchange for outstanding Company Shares and, after the Effective Time, if applicable, any cash and dividends or other distribution with respect to the Parent Common Stock to be issued or to be paid pursuant to the last sentence of Section 3.01(a) (together, the “Exchange Fund”). Promptly after the Effective Time (and in any event within three Business Days), Parent shall send, or shall cause the Exchange Agent to send, to each holder of Company Shares at the Effective Time a letter of transmittal and instructions (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates or transfer of the Uncertificated Company Shares to the Exchange Agent) for use in such exchange.

(b) Each holder of Company Shares that have been converted into the right to receive the Merger Consideration shall be entitled to receive, upon delivery of the Ownership Evidence, the Merger Consideration in respect of the Company Shares represented by a Certificate or Uncertificated Company Share and any cash and dividends or other distributions with respect to the Parent Common Stock to be issued or to be paid pursuant to the last sentence of Section 3.01(a). Until so surrendered or transferred, as the case may be, each such Certificate or Uncertificated Company Share shall represent after the Effective Time for all purposes only the right to receive such Merger Consideration.

(c) If any portion of the Merger Consideration is to be paid to a Person other than the Person in whose name the surrendered Certificate or the transferred Uncertificated Company Share is registered, it shall be a condition to such payment that (i) either such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer or such Uncertificated Company Share shall be properly transferred and (ii) the Person requesting such payment shall pay to the Exchange Agent any transfer or other taxes required as a result of such payment to a Person other than the registered holder of such Certificate or Uncertificated Company Share or establish to the satisfaction of the Exchange Agent that such tax has been paid or is not payable.

(d) The stock transfer books of the Company shall be closed immediately upon the Effective Time and there shall be no further registration of transfers of Company Shares thereafter on the records of the Company. If, after the Effective Time, Certificates or Uncertificated Company Shares are presented to

A-9

Parent, the Surviving Corporation or the Exchange Agent for any reason, they shall be canceled and exchanged for the Merger Consideration and cash, dividends or other distributions to the extent provided for, and in accordance with the procedures set forth, in this Article 3.

(e) Any portion of the Exchange Fund made available to the Exchange Agent pursuant to Section 3.02(a) that remains unclaimed by the holders of Company Shares six months after the Effective Time shall be delivered to Parent or otherwise on the instruction of Parent, and any such holder who has not exchanged Company Shares for the Merger Consideration in accordance with this Section 3.01 prior to that time shall thereafter look only to Parent for payment of the Merger Consideration, and any cash, dividends and distributions with respect thereto, in respect of such shares without any interest thereon. Notwithstanding the foregoing, Parent shall not be liable to any holder of Company Shares for any amounts paid to a public official pursuant to applicable abandoned property, escheat or similar laws. Any amounts remaining unclaimed by holders of Company Shares two years after the Effective Time (or such earlier date immediately prior to such time when the amounts would otherwise escheat to or become property of any Governmental Authority) shall become, to the extent permitted by Applicable Law, the property of Parent free and clear of any claims or interest of any Person previously entitled thereto.

(f) Whenever a dividend or other distribution is declared by Parent in respect of Parent Common Stock, the record date for which is at or after the Effective Time, that declaration shall include dividends or other distributions in respect of all shares of Parent Common Stock issuable pursuant to this Agreement. No dividends or other distributions in respect of such Parent Common Stock shall be paid to any holder of any unsurrendered or undelivered Ownership Evidence until such Ownership Evidence is provided to the Exchange Agent or Parent in accordance with this Article 3. Subject to the effect of Applicable Laws, following surrender or delivery, as applicable, of any such Ownership Evidence to the Exchange Agent or Parent in accordance with this Article 3, there shall be issued and/or paid to the holder of the Ownership Evidence representing whole shares of Parent Common Stock issued in exchange therefor, without interest, (A) at the time of such surrender or delivery, as the case may be, the dividends or other distributions with a record date at or after the Effective Time and a payment date on or prior to the date of issuance of such whole shares of Parent Common Stock and not previously paid and (B) at the appropriate payment date, the dividends or other distributions payable with respect to such whole shares of Parent Common Stock with a record date at or after the Effective Time on the Closing Date but with a payment date subsequent to surrender or delivery and not previously paid.

(g) Notwithstanding any other provision of this Agreement, no fractional shares of Parent Common Stock will be issued in respect of any Company Shares (including upon exchange of any Company Exchangeable Shares) and any holder of Company Shares (or Company Exchangeable Shares) entitled to receive a fractional share of Parent Common Stock but for this Section 3.02(g) shall be entitled to receive in lieu thereof an amount in cash (without interest) determined by multiplying such fraction (rounded to the nearest one-hundredth of a share) by the average closing sale prices for a share of Parent Common Stock on the New York Stock Exchange, Inc. (the “NYSE”) Composite Transactions Tape (as reported by The Wall Street Journal (Northeast edition), or, if not reported thereby, as reported by any other authoritative source) for each of the ten consecutive trading days ending with the second complete trading day prior to the Closing Date (not counting the Closing Date).

(h) Each of the Exchange Agent, Parent and the Surviving Corporation shall be entitled to deduct and withhold from the consideration otherwise payable to any Person pursuant to this Article 3 such amounts as it is required to deduct and withhold with respect to the making of such payment under any provision of any Applicable Law, including federal, state, provincial, local or foreign Tax law. If the Exchange Agent, Parent or the Surviving Corporation, as the case may be, so withholds amounts, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock in respect of which the Exchange Agent, Parent or the Surviving Corporation, as the case may be, made such deduction and withholding.

(i) In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and the posting by such

A-10

Person of a bond in the form customarily required by Parent as indemnity against any claim that may be made against it with respect to such Certificate, and the submission of such other documentation as Parent customarily requires for the replacement of lost, stolen or destroyed certificates, the Exchange Agent (or Parent pursuant to Section 3.02(e)) will deliver a certificate evidencing the ownership of such number of shares of Parent Common Stock and/or any cash, dividends and other distributions in respect thereof issuable and/or payable in exchange for such lost, stolen or destroyed Certificate pursuant to this Agreement.

(j) Notwithstanding anything herein to the contrary, Company Shares surrendered for exchange by an “affiliate” of the Company that will, after the Effective Time, be an “affiliate” of Parent, in each case as determined pursuant to Section 9.06, shall not be exchanged until Parent has received a written agreement from such Person as provided in Exhibit A.

Section 3.03 Appraisal Rights. In accordance with Section 262 of the DGCL, no appraisal rights shall be available to holders of Company Shares in connection with the Merger.

Section 3.04 Adjustments to Prevent Dilution. In the event that prior to the Effective Time there is a change in the number of Company Shares or shares of Parent Common Stock or securities convertible or exchangeable into or exercisable for Company Shares or shares of Parent Common Stock issued and outstanding as a result of a distribution, reclassification, stock split (including a reverse split), stock dividend or distribution, recapitalization, merger, subdivision, issuer tender or exchange offer, or other similar transaction, the Merger Consideration shall be equitably adjusted to eliminate the effects of such event on the Merger Consideration.

Section 3.05 Company Stock Options and Other Equity Awards; Warrants; Company Exchangeable Shares.

(a) At the Effective Time, each outstanding option to purchase Company Shares (a “Company Stock Option”) under any employee stock option or compensation plan or arrangement of the Company, whether vested or unvested, shall be converted into an option to acquire (subject to the same continued vesting, if applicable) a number of shares of Parent Common Stock equal to the product (rounded down to the nearest whole number) of (i) the number of Company Shares subject to the Company Stock Option immediately prior to the Effective Time and (ii) the Exchange Ratio, at an exercise price per share (rounded up to the nearest whole cent) equal to (A) the exercise price per Company Share of such Company Stock Option immediately prior to the Effective Time divided by (B) the Exchange Ratio; provided, however, that the exercise price and the number of shares of Parent Common Stock purchasable pursuant to the Company Stock Options shall be determined in a manner consistent with the requirements of Section 409A of the Code; and provided, further, that in the case of any Company Option to which Section 422 of the Code applies, the option price, the number of shares purchasable pursuant to such option and the terms and conditions of exercise of such option shall be determined in accordance with the foregoing, subject to such adjustments as are necessary in order to satisfy the requirements of Section 424(a) of the Code. Except as specifically provided above, following the Effective Time, each Company Stock Option shall continue to be governed by the same terms and conditions (including, without limitation, any vesting requirements) as were applicable under such Company Stock Option immediately prior to the Effective Time.

(b) At the Effective Time, each Company Restricted Stock Unit shall be deemed converted to the right to receive the number of shares of Parent Common Stock equal to the product (rounded down to the nearest whole number) of (i) the number of Company Shares subject to such Restricted Stock Unit immediately prior to the Effective Time and (ii) the Exchange Ratio. Except as specifically provided above, following the Effective Time, each Company Restricted Stock Unit shall continue to be governed by the same terms and conditions as were applicable under such Company Restricted Stock Unit immediately prior to the Effective Time.

(c) At the Effective Time, each right of any kind, contingent or accrued, to acquire or receive Company Shares or benefits measured by the value of Company Shares, and each award of any kind consisting of Company Shares that may be held, awarded, outstanding, payable or reserved for issuance under any employee stock option or compensation plan or arrangement of the Company other than Company Stock Options and rights granted under Company Restricted Stock Units (the “Company Awards”), shall be

A-11

deemed to be converted into the right to acquire or receive benefits measured by the value of the number of shares of Parent Common Stock equal to the product of (i) the number of Company Shares subject to such Company Award immediately prior to the Effective Time and (ii) the Exchange Ratio. If any such Company Award provided for an exercise price, such exercise price shall be adjusted as provided in Section 3.05(a) with respect to Company Stock Options, and each such right shall otherwise be subject to the terms and conditions applicable to such right under the relevant employee stock option or compensation plan or arrangement of the Company. Except as specifically provided above, following the Effective Time, each Company Award shall continue to be governed by the same terms and conditions (including, without limitation, any vesting requirements) as were applicable under such Company Award immediately prior to the Effective Time.

(d) At or prior to the Effective Time, the board of directors of the Company shall adopt such resolutions, and the Company shall otherwise take all actions, as are necessary to effectuate the provisions of Sections 3.05(a), (b) and (c).

(e) At the Effective Time, the Warrant shall be converted into the right to purchase and receive (in lieu of the shares of Company Common Stock purchasable and receivable upon the exercise of the rights represented by the Warrant immediately prior to Closing) a number of shares of Parent Common Stock equal to the product (rounded down to the nearest whole number) of (i) the number of Company Shares subject to the Warrant immediately prior to the Effective Time and (ii) the Exchange Ratio, at an exercise price per share (rounded up to the nearest whole cent) equal to (A) the exercise price per Company Share of such Warrant immediately prior to the Effective Time divided by (B) the Exchange Ratio.

(f) In the event the holders of the Company Exchangeable Shares approve the Exchangeable Share Amendment, (i) at and following the Effective Time, each of the Company Exchangeable Shares issued and outstanding immediately prior to the Effective Time shall (in lieu of the shares of Company Common Stock issuable upon the exchange therefor immediately prior to Closing) become exchangeable for the number of shares of Parent Common Stock equal to the Exchange Ratio, subject to Section 3.02(g) hereof with respect to the issuance of fractional shares upon conversion thereof; (ii) at or before the Effective Time, Parent shall execute and deliver the Voting and Support Supplement wherein the Parent agrees to be bound by the terms and provisions of the Voting and Support Agreements, in a form reasonably satisfactory to the Trustee and to Parent, and, to the satisfaction of the Trustee, preserving and not impairing in any material respect, any of the rights, duties, powers and authorities of the Trustee or the holders of Company Exchangeable Shares under the Voting and Support Agreements and the parties shall effect any other amendments of the Exchangeable Share Documents necessary to give effect to the provisions hereof; and (iii) at or prior to the Effective Time, Parent shall have authorized the Parent Special Voting Preferred Stock and shall deliver to the Trustee a new certificate evidencing the Parent Special Voting Preferred Stock, to the extent required under the Voting and Support Supplement. In the event the holders of the Company Exchangeable Shares do not approve the Exchangeable Share Amendment at a meeting held or by written consent sought for such purpose, the Company shall take action necessary to (a) cause Canadian Sub to exercise its right to redeem, at the Effective Time, all of the outstanding Company Exchangeable Shares or (b) acquire or cause CallRightCo to acquire at the Effective Time all of the outstanding Company Exchangeable Shares.

(g) Prior to the Effective Time, the Company shall obtain any consents from holders of Company Stock Options, the Company Restricted Stock Units, the Warrants and the Company Exchangeable Shares and make any amendments to the terms of such equity or compensation plans or arrangements, the Warrants or the plans or arrangements relating to the Company Exchangeable Shares that are necessary to give effect to the transactions contemplated by this Section 3.03 and to ensure compliance with Section 409A of the Code. Notwithstanding any other provision of this Agreement, payment may be withheld in respect of any Company Stock Option or Company Restricted Stock Units until such necessary consents are obtained. The Company shall take all necessary action to ensure that the Surviving Corporation will not be bound at the Effective Time by any options, or other rights, awards or arrangements under any employee stock option or compensation plan or arrangement or other third party agreements of the Company that would entitle any Person after the Effective Time to beneficially own any Company Shares or to receive any payments in respect thereof.

A-12

(h) If registration of any interest in Parent’s 2001 Incentive Stock Plan (or other applicable equity incentive plan) or the shares of Parent Common Stock issuable thereunder is required under the 1933 Act, Parent shall file with the SEC within three (3) Business Days after the Effective Time a registration statement on Form S-8 with respect to such interests or Parent Common Stock, and shall use its reasonable best efforts to maintain the effectiveness of such registration statement for so long as the relevant stock plans remain in effect and such registration of interests therein or the shares of Parent Common Stock issuable thereunder continues to be required.

(b) Notwithstanding the foregoing, at any time prior to the adoption of this Agreement by the Company’s stockholders (and in no event after the adoption of this Agreement by the Company’s stockholders), the Board of Directors of the Company, directly or indirectly through advisors, agents or other intermediaries, may, subject to compliance with Section 7.03(c), (i) engage in negotiations or discussions with any Third Party that, subject to the Company’s compliance with Section 7.03(a) has made after the date of this Agreement a Superior Proposal or an unsolicited bona fide Acquisition Proposal that the Board of Directors of the Company reasonably believes (after considering the advice of a financial advisor of nationally recognized reputation and outside legal counsel) is reasonably likely to lead to a Superior Proposal, (ii) thereafter furnish to such Third Party nonpublic information relating to the Company or any of its Subsidiaries pursuant to a confidentiality agreement with terms no less favorable to the Company than those contained in the Confidentiality Agreement (a copy of which shall be provided, promptly after its execution, for informational purposes only to Parent), it being understood that such confidentiality agreement need not contain a standstill provision; provided that all such information (to the extent that such information has not been previously provided or made available to Parent) is provided or made available to Parent, as the case may be, prior to or substantially concurrently with the time it is provided or made available to such Third Party) and (iii) following receipt of a Superior Proposal after the date of this Agreement or a development or a change in circumstances occurs or arises after the date of this Agreement that was not known by the Company’s board of directors as of the date of this Agreement (such material development or change in circumstance, an “Intervening Event”), make an Adverse Recommendation Change, but in each case referred to in the foregoing clauses (i) through (iii) only if the Board of Directors of the Company determines in good faith by a majority vote, after considering advice from outside legal counsel to the Company, that in light of such Superior Proposal or Intervening Event, such action is required in order for the Board to comply with its fiduciary duties under Applicable Law. Nothing contained herein shall prevent the Board of Directors of the Company from complying with requirements of Rule 14e-2(a) and Rule 14d-9 under the 1934 Act with regard to an Acquisition Proposal, so long as any action taken or statement made to so comply is consistent with this Section 7.03; provided, that such requirement will in no way eliminate or modify the effect that any action pursuant to such requirement would otherwise have under this Agreement.

(c) The Board of Directors of the Company shall not take any of the actions referred to in clauses (i) through (iii) of Section 7.03(b) unless the Company shall have delivered to Parent a prior written notice advising Parent that it intends to take such action.

COVENANTS OF PARENT

Parent agrees that:

Section 8.01 Conduct of Parent. To the fullest extent permitted by Applicable Law, from the date of this Agreement until the Effective Time, except as set forth on Section 8.01 of the Parent Disclosure Schedule, or with the Company’s prior written consent (not to be unreasonably withheld or delayed), Parent shall not, and shall not permit any of its Subsidiaries to:

(d) take any action that would make any representation or warranty of Parent hereunder inaccurate in any material respect at, or as of any time before, the Effective Time or would materially delay the Closing; or

(e) agree, resolve or commit to do any of the foregoing with an effective date prior to the Effective Time.

Section 8.02 Obligations of Merger Subsidiary. Parent shall take all action necessary to cause Merger Subsidiary to perform its obligations under this Agreement and to consummate the Merger on the terms and conditions set forth in this Agreement.

(a) From and after the Effective Time, each of Parent and the Surviving Corporation shall indemnify and hold harmless the present and former officers and directors of the Company (each an “Indemnified Person”) in respect of acts or omissions occurring at or prior to the Effective Time to the fullest extent permitted by Delaware Law or any other Applicable Law or provided under the Company’s certificate of incorporation and bylaws in effect on the date of this Agreement; provided that such indemnification shall be subject to any limitation imposed from time to time under Applicable Law and Parent or Surviving Corporation shall also advance expenses as incurred to the fullest extent provided under the Company’s certificate of incorporation and bylaws in effect on the date of this Agreement, provided the Person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Person is not entitled to indemnification in a form reasonably satisfactory to Parent.

(b) For six years after the Effective Time, Parent or the Surviving Corporation shall provide officers’ and directors’ liability insurance in respect of acts or omissions occurring prior to the Effective Time covering each such Indemnified Person covered as of the date of this Agreement by the Company’s officers’ and directors’ liability insurance policy on terms with respect to coverage and amount no less favorable than those of such policy in effect on the date of this Agreement; provided that, in satisfying its obligation to provide such insurance coverage, the Surviving Corporation shall not be obligated to pay an annual premium in excess of 200% of the Company’s current annual premium for such insurance, which amount the Company has disclosed to Parent prior to the date of this Agreement; provided further, that if the annual premiums of such insurance coverage exceed such amount, Parent or the Surviving Corporation shall be

A-35

obligated to obtain a policy with the greatest coverage available for a cost not exceeding such amount. Notwithstanding the foregoing, at the Company’s election (prior to the Closing) or Parent’s election (subsequent to the Closing), in lieu of obtaining or providing the officers’ and directors’ liability insurance coverage contemplated above, Company may prior to the Closing or Parent or the Surviving Corporation may subsequent to the Closing purchase a non-cancelable “tail” coverage insurance policy under the Company’s current officers’ and directors’ liability insurance policies (providing coverage not less favorable than provided by such insurance in effect on the date hereof), which tail policy shall be effective for a period from the Effective Time through and including the date six years from the Closing Date, covering each Indemnified Person covered as of the date of this Agreement by the Company’s officers’ and directors’ liability insurance policies in respect of acts or omissions occurring prior to the Effective Time; provided that the Company shall not pay a premium for such tail insurance prior to the Closing in an amount that exceeds 200% of the Company’s current annual premium for such insurance.

(b) With respect to any employee benefit plan in which any Affected Employee first becomes eligible to participate, on or after the Effective Time (the “New Company Plans”), Parent shall: (i) waive all pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to such Affected Employee under any health and welfare New Company Plans in which such Affected Employee may be eligible to participate after the Effective Time and (ii) recognize service of Affected Employees (or otherwise credited by the Company or its Subsidiaries) accrued prior to the Effective Time for purposes of eligibility to participate, vesting and level of benefits (but not for the purposes of benefit accrual under defined benefit pension plans) under any New Company Plan in which such Affected Employees may be eligible to participate after the Effective Time, provided, however, that in no event shall any credit be given to the extent it would result in the duplication of benefits for the same period of service.

(c) It is understood that Parent’s expressed intention to extend offers of continued employment as set forth in this Section 8.05 shall not constitute any commitment, contract or understanding (expressed or implied) of any obligation on the part of Parent or its Subsidiaries to a post Closing employment relationship of any fixed term or duration or upon any terms or conditions other than the provisions of

A-36

Sections 8.05(a) and (b); provided that, from the Closing Date through the first anniversary thereof, Parent shall provide, or shall cause to be provided, to Affected Employees who remain employed with Parent or its Subsidiaries compensation and benefits at a level consistent with Section 8.05(a) above.

Subject to the proviso in the second preceding sentence, nothing in this Agreement shall be deemed to prevent or restrict in any way the right of Parent to terminate, reassign, promote or demote any of the Affected Employees after the Closing or to change adversely or favorably the title, powers, duties, responsibilities, functions locations, salaries, other compensation or terms or conditions of employment of such employees.

(d) Prior to the Effective Time, Parent shall establish reasonable severance policies to facilitate the transition of the Company’s operations following Closing, which severance policies shall be reasonably comparable to the severance benefits available to similarly situated employees of Parent and its Subsidiaries.

Section 12.02 Survival of Representations and Warranties. The representations and warranties contained herein and in any certificate or other writing delivered pursuant hereto shall not survive the Effective Time.

Section 12.03 Amendments and Waivers.

(a) Any provision of this Agreement may be amended or waived prior to the Effective Time if, but only if, such amendment or waiver is in writing and is signed, in the case of an amendment, by each party to this

A-44

Agreement or, in the case of a waiver, by each party against whom the waiver is to be effective; provided that, after the Company Stockholder Approval there shall be no amendment or waiver that pursuant to Delaware Law requires further Company Stockholder Approval without their further approval.

(b) No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by Applicable Law.

Section 12.04 Expenses.

(a) Except as otherwise provided herein, all costs and expenses incurred in connection with this Agreement shall be paid by the party incurring such cost or expense; provided however, Parent and the Company shall each bear and pay one half of (i) the filing fee for filing the Registration Statement with the SEC, and the costs and expenses incurred in connection with the filing, printing and mailing of the Proxy Statement/Prospectus and the Registration Statement (other than attorneys and accountants’ fees and expenses, which shall be paid by the party incurring such expense), and (ii) the filing fees for the Notification and Report Forms filed with the U.S. Federal Trade Commission and the Antitrust Division under the HSR Act and any premerger notification and reports formed under similar applicable antitrust law of any non-United States governmental antitrust authority.

(b) If a Payment Event (as hereinafter defined) occurs, the Company shall pay Parent (by wire transfer of immediately available funds), within two Business Days following such Payment Event, a fee equal to $10,000,000 (the “Termination Fee”).

“Payment Event” means the termination of this Agreement pursuant to (x) Section 11.01(d)(i), (y) Section 11.01(b)(i) (if a vote of the stockholders of the Company at the Company Stockholder Meeting to obtain the Company Stockholder Approval shall not have been held prior to such termination) or (z) Section 11.01(c)(i) but only if, (A) in the case of clause (y), both (1) after the date hereof and prior to the Company Stockholder Meeting, or the date of termination, as the case may be, an Acquisition Proposal shall have been made, and (2) within 12 months following the date of such termination: (I) the Company merges with or into, or is acquired, directly or indirectly, by merger or otherwise by, the Person making such Acquisition Proposal; (II) such Person, directly or indirectly, acquires more than 50% of the total assets of the Company and its Subsidiaries, taken as a whole; or (III) such Person, directly or indirectly, acquires more than 50% of the outstanding Company Shares (or in any of clauses (I) through (III) the Company shall have entered into any contract or agreement providing for such action, in which case the Payment Event shall be the later date on which such action is completed) and (B) in the case of clause (z) such Adverse Recommendation Change or failure to confirm the Company Board Recommendation was not solely the result of the occurrence of a Material Adverse Effect on Parent.

(c) The Company acknowledges that the agreements contained in this Section 12.04 are an integral part of the transactions contemplated by this Agreement and that, without these agreements, Parent and Merger Subsidiary would not enter into this Agreement. Accordingly, if the Company fails promptly to pay any amount due to Parent or Merger Subsidiary pursuant to this Section 12.04, it shall also pay any costs and expenses (including attorneys’ fees) incurred by Parent or Merger Subsidiary in connection with a legal action to enforce this Agreement that results in a judgment against the Company for such amount, together with interest on any amount of the Termination Fee at a rate per annum equal to 3% over the prime rate (as published in The Wall Street Journal) in effect on the date such payment should have been made.

Section 12.05 Binding Effect; Benefit; Assignment.

(a) The provisions of this Agreement shall be binding upon and, except as provided in Section 8.04, shall inure to the benefit of the parties hereto and their respective successors and assigns. Except as provided

A-45

in Section 8.04, no provision of this Agreement is intended to confer any rights, benefits, remedies, obligations or liabilities hereunder upon any Person other than the parties hereto and their respective successors and assigns.

(b) No party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the consent of each other party hereto, except that Parent or Merger Subsidiary may transfer or assign its rights and obligations under this Agreement, in whole or from time to time in part, to (i) one or more of their Affiliates at any time and (ii) after the Effective Time, to any Person; provided that such transfer or assignment shall not relieve Parent or Merger Subsidiary of its obligations hereunder or enlarge, alter or change any obligation of any other party hereto or due to Parent or Merger Subsidiary.

Section 12.06 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to the conflicts of law rules of such state, except to the extent that Delaware Law is mandatorily applicable to the Merger.

Section 12.07 Jurisdiction. The parties hereto agree that any suit, action or proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby shall be brought in the United States District Court for the Southern District of New York or any New York State court sitting in the City of New York, so long as one of such courts shall have subject matter jurisdiction over such suit, action or proceeding, and that any cause of action arising out of this Agreement shall be deemed to have arisen from a transaction of business in the State of New York, and each of the parties hereby irrevocably consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such suit, action or proceeding and irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. Process in any such suit, action or proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each party agrees that service of process on such party as provided in Section 12.01 shall be deemed effective service of process on such party.

Section 12.08 Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 12.09 Counterparts; Effectiveness. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective when each party hereto shall have received a counterpart hereof signed by all of the other parties hereto. Until and unless each party has received a counterpart hereof signed by the other party hereto, this Agreement shall have no effect and no party shall have any right or obligation hereunder (whether by virtue of any other oral or written agreement or other communication).

Section 12.10 Entire Agreement. This Agreement and the Confidentiality Agreement constitute the entire agreement between the parties with respect to the subject matter thereof and supersede all prior agreements and understandings, both oral and written, between the parties with respect to the subject matter thereof.

Section 12.11 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other Governmental Authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such a determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

A-46

Section 12.12 Specific Performance. The parties hereto agree that irreparable damage would occur if any provision of this Agreement were not performed in accordance with the terms hereof and that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof in any court specified in Section 12.07, in addition to any other remedy to which they are entitled at law or in equity.

FORM OF AFFILIATE LETTER

Ladies and Gentlemen:

I have been advised that as of the date hereof I may be deemed to be an “affiliate” of THOMAS WEISEL PARTNERS GROUP, INC. (the “Company”), as the term “affiliate” is defined for purposes of paragraphs (c) and (d) of Rule 145 (“Rule 145”) of the rules and regulations (the “Rules and Regulations”) of the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the “Act”).

I have been further advised that, pursuant to the terms of the Agreement and Plan of Merger, dated as of , 2010 (the “Merger Agreement”), by and among the Company, STIFEL FINANCIAL CORP. (“Parent”) and PTAS, INC. (“Merger Subsidiary”), Merger Subsidiary will be merged with and into the Company (the “Merger”), and I may be eligible to receive shares of common stock of Parent (“Parent Common Stock”) in exchange in part for shares of common stock of the Company owned by me. Capitalized terms used herein and not otherwise defined have the meanings assigned to them in the Merger Agreement.

I hereby represent, warrant and covenant to Parent that, in the event I receive any Parent Common Stock pursuant to the Merger:

1. I shall not make any sale, transfer or other disposition of the Parent Common Stock to be received by me pursuant to the Merger or any other securities that may be paid as a dividend or otherwise distributed thereon or with respect thereto or issued or delivered in exchange or substitution thereof (all such shares being referred as “Control Securities”) in violation of the Act or the Rules and Regulations.

2. I have carefully read this letter and the Merger Agreement and discussed their requirements and other applicable limitations upon my ability to sell, transfer or otherwise dispose of Control Securities to the extent I believed necessary with my counsel or with counsel for the Company.

3. I have been advised that any issuance of Parent Common Stock to me pursuant to the Merger Agreement will be registered with the SEC on a registration statement on Form S-4 (the “Parent S-4”). However, I have also been advised that, since at the time the Merger is submitted to the stockholders of the Company for approval, I may be deemed to be an “affiliate” of the Company, any sale or disposition by me of any of the Control Securities may only be made, in accordance with the provisions of paragraph (d) of Rule 145 under the Act, pursuant to an effective registration statement under the Act or pursuant to an exemption thereunder. I agree that I will not sell, transfer or otherwise dispose of Control Securities unless (i) such sale, transfer or other disposition has been registered under the Act for resale (and that the Parent S-4 will not provide such registration); (ii) I provide evidence of compliance with Rule 145(d)(1), in a letter in the form of Annex I hereto, or such sale, transfer or other disposition is otherwise made in conformity with the provisions of Rule 145 promulgated by the SEC under the Act; or (iii) in the written opinion of counsel, which opinion and counsel shall be reasonably acceptable to Parent, such sale, transfer or other disposition is otherwise exempt from registration under the Act.

4. I understand that Parent is under no obligation to register the sale, transfer or other disposition of the Control Securities by me or on my behalf.

5. I understand that stop transfer instructions will be given to Parent’s transfer agent with respect to the Control Securities and that there will be placed on any certificates for the Control Securities issued to me, or any substitutions therefor, a legend stating in substance:

“The shares represented by this certificate were issued in a transaction to which Rule 145 promulgated under the Securities Act of 1933, as amended, applies. The shares represented by this certificate may only be sold or otherwise transferred in accordance with the terms of a letter agreement between the registered holder hereof and Stifel Financial Corp., a copy of which agreement is on file at the principal offices of Stifel Financial Corp.”

6. I also understand that, unless the transfer by me of my Control Securities has been registered under the Act or is a sale made in conformity with the provisions of Rule 145(d), Parent reserves the right to put the following legend on the certificates issued to my transferee:

“The sale of the shares represented by this certificate has not been registered under the Securities Act of 1933, as amended (the “Securities Act”), and the shares were acquired from a person who received such shares in a transaction to which Rule 145 promulgated under the Securities Act applies. The shares have been acquired by the holder not with a view to, or for resale in connection with, any distribution thereof within the meaning of the Securities Act and may not be sold, pledged or otherwise transferred except in accordance with an exemption from the registration requirements of the Securities Act.”

It is understood and agreed that this letter agreement shall terminate and be of no further force or effect and the legends set forth in paragraphs (5) or (6), as the case may be, above shall be removed by delivery of substitute certificates without such legend, and the related stop transfer restrictions shall be lifted forthwith, if (i) any such Control Securities shall have been registered under the Act for sale, transfer or other disposition by me or on my behalf and are sold, transferred or otherwise disposed of; (ii) I provide evidence that any such Control Securities are sold in accordance with the provisions of Rule 145(d)(1) promulgated under the Act in the form of a letter in the form of Annex I hereto; (iii) if Parent meets the requirements of Rule 144(c) under the Securities Act, if I provide a letter to the effect I am not and have not been for at least three months at the time an affiliate of Parent and have been the beneficial owner of the Parent Common Stock for at least six months (or such other period as may be prescribed by the Act and the Rules and Regulations); or (iv) if I provide a letter that I am not and have not been for at least three months an affiliate of Parent and have been the beneficial owner of the Parent Common Stock for at least one year (or such other period as may be prescribed by the Act and the Rules and Regulations); or (v) Parent shall have received a letter from the staff of the SEC, or a written opinion of counsel, which opinion and counsel shall be reasonably acceptable to Parent, or other evidence reasonably satisfactory to Parent, to the effect that the stock transfer restrictions and the legend are not required.

My execution of this letter shall not be considered an admission on my part that I am an “affiliate” of the Company as described in the first paragraph of this letter or as a waiver of any rights I may have to object to any claim that I am such an affiliate on or after the date of this letter.

This letter shall terminate and be of no further force and effect if the Merger Agreement is terminated in accordance with its terms.

This letter shall be governed by the laws of the State of New York.

We also understand that, among other things, pursuant to Section 2.6(b) of the Support Agreement, dated as of January 2, 2008, by and among the Company, TWP Holdings Company (Canada), ULC and TWP Acquisition Company (Canada), Inc., an indirect subsidiary of the Company (“Canadian Sub”), the Company may not, in certain circumstances without the prior approval of Canadian Sub and the prior approval of the holders of the outstanding exchangeable shares of Canadian Sub (the “Company Exchangeable Shares” and, together with the shares of Company Common Stock, the “Shares”) reclassify or otherwise change the shares of Company Common Stock or effect an amalgamation, merger, reorganization or other transaction affecting the shares of Company Common Stock unless the same or an economically equivalent change shall simultaneously be made to, or in, the rights of the holders of the Company Exchangeable Shares.

You have requested that Houlihan Lokey Howard & Zukin Financial Advisors, Inc. (“Houlihan Lokey”) provide an opinion (the “Opinion”) to the Board of Directors of the Company (the “Board”) as to whether, as of the date hereof, the Exchange Ratio provided for in the Transaction is fair to the holders of Shares from a financial point of view. At your instruction, in evaluating whether the Exchange Ratio provided for in the Transaction is fair to the holders of Company Exchangeable Shares from a financial point of view we treated and otherwise evaluated the Company Exchangeable Shares on an as-exchanged basis, after giving effect to the exchange of all of the outstanding Company Exchangeable Shares for an equivalent number of shares of Company Common Stock.

In connection with this Opinion, we have made such reviews, analyses and inquiries as we have deemed necessary and appropriate under the circumstances. Among other things, we have:

reviewed a draft, dated April 25, 2010, of the Agreement;

reviewed certain publicly available business and financial information relating to the Company and the Acquiror that we deemed to be relevant (and adjustments thereto), including certain publicly available research analyst estimates with respect to the future financial performance and condition including, without limitation, the net tangible book value and net revenue, of the Company and the Acquiror (the “Street Estimates”);

reviewed certain information relating to the historical, current and future operations, financial condition and prospects of the Company and the Acquiror made available to us by the Company and the Acquiror, including financial projections (and adjustments thereto) prepared by the management of the Company relating to the Company for the fiscal year ending December 31, 2010 (the “Company Projections”);

B-1

spoken with certain members of the managements of the Company and the Acquiror and certain of their respective representatives and advisors regarding the businesses, operations, financial condition and prospects of the Company and the Acquiror, respectively, the Transaction and related matters;

compared the financial and operating performance of the Company and the Acquiror with that of other companies with publicly traded securities that we deemed to be relevant;

reviewed the current and historical market prices and trading volume for certain of the Company’s and the Acquiror’s publicly traded securities, and the historical market prices and certain financial data of the publicly traded securities of certain other companies that we deemed to be relevant;

compared the relative contributions of the Company and the Acquiror to certain financial statistics of the combined company on a pro forma basis; and

conducted such other financial studies, analyses and inquiries and considered such other information and factors as we deemed appropriate.

We have relied upon and assumed, without independent verification, the accuracy and completeness of all data, material and other information furnished, or otherwise made available, to us, discussed with or reviewed by us, or publicly available, and do not assume any responsibility with respect to such data, material and other information. In addition, management of the Company has advised us, and we have assumed, that the Company Projections reviewed by us have been reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of such management as to the future financial results and condition of the Company for the fiscal year ending December 31, 2010, and we express no opinion with respect to such projections or the assumptions on which they are based. As you are aware, we were not provided by the Company or the Acquiror with any projections with respect to the future operations, financial condition and prospects of the Company or the Acquiror other than the Company Projections and, at your instruction, we have used and relied upon the Street Estimates with respect to the Company and the Acquiror referred to above, which we understand are a reasonable basis on which to evaluate the future financial performance of the Company and the Acquiror and are appropriate for such purposes. We do not assume any responsibility for the accuracy, validity or completeness of the Street Estimates or express any opinion with respect to such estimates or the assumptions on which they are based. We have relied upon and assumed, without independent verification, that there has been no change in the business, assets, liabilities, financial condition, results of operations, cash flows or prospects of the Company or the Acquiror since the date of the most recent financial statements provided to us that would be material to our analyses or this Opinion, and that there is no information or any facts that would make any of the information reviewed by us incomplete or misleading.

We have relied upon and assumed, without independent verification, that to the extent material to our analyses and this Opinion (a) the representations and warranties of all parties to the Agreement and all other related documents and instruments that are referred to therein are true and correct, (b) each party to the Agreement and such other related documents and instruments will fully and timely perform all of the covenants and agreements required to be performed by such party, (c) all conditions to the consummation of the Transaction will be satisfied without waiver thereof, and (d) the Transaction will be consummated in a timely manner in accordance with the terms described in the Agreement and such other related documents and instruments, without any amendments, modifications or waiver thereto. We have also assumed, with your consent, that the Transaction will be treated as a tax-free transaction. We also have relied upon and assumed, without independent verification, that (i) the Transaction will be consummated in a manner that complies in all respects with all applicable federal and state statutes, rules and regulations, and (ii) all governmental, regulatory, and other consents and approvals necessary for the consummation of the Transaction will be obtained and that no delay, limitations, restrictions or conditions will be imposed or amendments, modifications or waivers made that would result in the disposition of any assets of the Company or the Acquiror, or otherwise have an effect on the Company or the Acquiror or any expected benefits of the Transaction that would be material to our analyses or this Opinion. In addition, we have relied upon and assumed, without independent verification, that the final form of the Agreement will not differ in any respect from the draft of the Agreement identified above.

B-2

Furthermore, in connection with this Opinion, we have not been requested to make, and have not made, any physical inspection or independent appraisal or evaluation of any of the assets, properties or liabilities (fixed, contingent, derivative, off-balance-sheet or otherwise) of the Company, the Acquiror or any other party, nor were we provided with any such appraisal or evaluation. We did not estimate, and express no opinion regarding, the liquidation value of any entity or business. We have undertaken no independent analysis of any potential or actual litigation, regulatory action, possible unasserted claims or other contingent liabilities, to which the Company or the Acquiror is or may be a party or is or may be subject, or of any governmental investigation of any possible unasserted claims or other contingent liabilities to which the Company or the Acquiror is or may be a party or is or may be subject.

We have not been requested to, and did not, (a) initiate or participate in any discussions or negotiations with, or solicit any indications of interest from, third parties with respect to the Transaction, the securities, assets, businesses or operations of the Company or any other party, or any alternatives to the Transaction, (b) negotiate the terms of the Transaction, or (c) advise the Board, the Company or any other party with respect to alternatives to the Transaction. This Opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. We have not undertaken, and are under no obligation, to update, revise, reaffirm or withdraw this Opinion, or otherwise comment on or consider events occurring or coming to our attention after the date hereof. We are not expressing any opinion as to what the value of Acquiror Common Stock actually will be when issued pursuant to the Transaction or the price or range of prices at which Company Common Stock, the Company Exchangeable Shares or Acquiror Common Stock may be purchased or sold at any time. We have assumed that the Acquiror Common Stock to be issued to holders of Shares in the Transaction will be listed on The New York Stock Exchange.

This Opinion is furnished for the use and benefit of the Board (solely in its capacity as such) in connection with its consideration of the Transaction and may not be used for any other purpose without our prior written consent. This Opinion should not be construed as creating any fiduciary duty on Houlihan Lokey’s part to any party. This Opinion is not intended to be, and does not constitute, a recommendation to the Board, the Company, any security holder or any other person as to how to act or vote with respect to any matter relating to the Transaction.

B-3

We will receive a fee for rendering certain financial advice to the Company with respect to the Transaction, including this Opinion, which is not contingent upon the successful completion of the Transaction. The Company has also agreed to reimburse certain of our expenses and to indemnify us and certain related parties for certain potential liabilities arising out of our engagement.

In addition, we have not been requested to opine as to and this Opinion does not express an opinion as to or otherwise address, among other things: (i) the underlying business decision of the Company, the holders of any Shares or any other securities of the Company or any other party to proceed with or effect the Transaction, (ii) the terms of any arrangements, understandings, agreements or documents related to, or the form, structure or any other portion or aspect of, the Transaction or otherwise (other than the Exchange Ratio to the extent expressly specified herein), (iii) the fairness of any portion or aspect of the Transaction to the holders of any class of securities, creditors or other constituencies of the Company, any of its subsidiaries or the Acquiror, or to any other party, except if and only to the extent expressly set forth in the last sentence of this Opinion, (iv) the relative merits of the Transaction as compared to any alternative business strategies that might exist for the Company, any of its subsidiaries or any other party or the effect of any other transaction in which the Company, any of its subsidiaries or any other party might engage, (v) the fairness of any portion or aspect of the Transaction to any one class or group of the Company’s, any of its subsidiaries’ or any other party’s security holders vis-à-vis any other class or group of the Company’s, any of its subsidiaries’ or such other party’s security holders (including, without limitation, the allocation of any consideration amongst or within such classes or groups of security holders), (vi) whether or not the Company, any of its subsidiaries, the Acquiror, their respective security holders or any other party is receiving or paying reasonably equivalent value in the Transaction, (vii) the solvency, creditworthiness or fair value of the Company, any of its subsidiaries or any other participant in the Transaction, or any of their respective assets, under any applicable laws relating to bankruptcy, insolvency, fraudulent conveyance or similar matters, or (viii) the fairness, financial or otherwise, of the amount, nature, or any other aspect of any compensation to or consideration payable to or received by any officers, directors or employees of any party to the Transaction (in their capacity as such) or any class of such persons, relative to the Exchange Ratio or otherwise. Furthermore, no opinion, counsel or interpretation is intended in matters that require legal, regulatory, accounting, insurance, tax or other similar professional advice. It is assumed that such opinions, counsel or interpretations have been or will be obtained from the appropriate professional sources. Furthermore, we have relied, with your consent, on the assessments by the Company, the Acquiror and their respective advisors, as to all legal, regulatory, accounting, insurance and tax matters with respect to the Company, the Acquiror and the Transaction. The issuance of this Opinion was approved by a committee authorized to approve opinions of this nature.

Based upon and subject to the foregoing, and in reliance thereon, it is our opinion that, as of the date hereof, the Exchange Ratio provided for in the Transaction is fair to the holders of Shares from a financial point of view.

Very truly yours,

Annex C

Supplemental Information for the Holders of Exchangeable Shares

Background

The exchangeable shares of TWP Acquisition Company (Canada), Inc. (referred to as Canadian Sub) were issued in connection with Thomas Weisel Partners Group, Inc.’s (referred to as Thomas Weisel Partners) acquisition of Westwind Capital Corporation in January 2008. Each exchangeable share is exchangeable at any time for one share of Thomas Weisel Partners common stock. The Thomas Weisel Partners special voting preferred stock and the Voting and Exchange Trust Agreement provide a mechanism for holders of exchangeable shares, which are intended to have substantially the same voting rights as Thomas Weisel Partners common stock, to vote with Thomas Weisel Partners common stock. The share of Thomas Weisel Partners special voting preferred stock that is issued and outstanding is entitled to one vote for each exchangeable share, excluding shares held by Thomas Weisel Partners or any person directly or indirectly controlled by or under common control with Thomas Weisel Partners, on all matters on which Thomas Weisel Partners common stock is entitled to vote.

Thomas Weisel Partners Special Voting Preferred Stock

When the exchangeable shares were originally issued, Thomas Weisel Partners also issued one share of Thomas Weisel Partners special voting preferred stock. The one share of Thomas Weisel Partners special voting preferred stock is held by CIBC Mellon Trust Company in its capacity as trustee for the holders of exchangeable shares pursuant to the terms of the Voting and Exchange Trust Agreement referred to below. The one share of Thomas Weisel Partners special voting preferred stock has attached to it a number of votes equal to the number of exchangeable shares outstanding from time to time, other than exchangeable shares held by Thomas Weisel Partners or any person directly or indirectly controlled by or under common control with Thomas Weisel Partners. The holder of the one share of Thomas Weisel Partners special voting preferred stock is not entitled to dividends but is entitled to vote with the holders of Thomas Weisel Partners common stock as a single class. The one share of Thomas Weisel Partners special voting preferred stock, together with the operation of the Voting and Exchange Trust Agreement, effectively entitles holders of exchangeable shares to vote as if they held shares of Thomas Weisel Partners common stock.

Voting and Exchange Trust Agreement and Support Agreement

In connection with the acquisition of Westwind Capital Corporation and the issuance of the exchangeable shares, Thomas Weisel Partners, Canadian Sub and CIBC Mellon Trust Company, as trustee, entered into a Voting and Exchange Trust Agreement and Thomas Weisel Partners, TWP Holdings Company (Canada), ULC and Canadian Sub entered into a Support Agreement. Among other things, the Voting and Exchange Trust Agreement entitles a holder of exchangeable shares to instruct the trustee as to the exercise of one of the votes attached to the one share of Thomas Weisel Partners special voting preferred stock in respect of each exchangeable share held by such holder. These votes may be exercised at all meetings, and in respect of all matters at or on which holders of Thomas Weisel Partners common stock are entitled to vote. In this regard, holders of exchangeable shares will, in effect, be entitled to vote in connection with the merger in the same manner as holders of Thomas Weisel Partners common stock. As part of the transaction, the trustee will be soliciting the instructions of holders of exchangeable shares as to the voting of the votes attached to the one share of Thomas Weisel Partners special voting preferred stock outstanding in connection with the merger.

The Support Agreement contains obligations of Thomas Weisel Partners in connection with a merger transaction such as the merger. In this regard, Thomas Weisel Partners may not, without the approval of Canadian Sub and the holders of the exchangeable shares, undertake a merger unless, as part of such transaction, an economically equivalent change to the rights of holders of exchangeable shares is made. The holders of the

C-1

exchangeable shares will be asked to approve an amendment to the articles of Canadian Sub to permit (at the discretion of the board of directors of Canadian Sub) their exchangeable shares to continue to remain outstanding following a change of control of Thomas Weisel Partners (referred to as the Exchangeable Share Amendment). On the assumption that the Exchangeable Share Amendment will be approved, the board of directors of Canadian Sub has determined that the treatment of holders of exchangeable shares outstanding at the effective time of the merger and pursuant to the merger (which treatment is described below) will result in an economically equivalent change to the rights of such holders such that the consent of Canadian Sub and the holders of the exchangeable shares to the merger is not required. The board of directors of Canadian Sub is appointed by its sole common shareholder, TWP Holdings Company (Canada), ULC, a wholly owned subsidiary of Thomas Weisel Partners.

In determining whether the economic equivalence standards discussed above have been met, the board of directors of Canadian Sub took into account the provisions in the merger agreement that require Stifel Financial Corp. (referred to as Stifel), Thomas Weisel Partners and Canadian Sub to take such actions as are reasonably required to:

•

ensure that shares of Stifel common stock can be issued to holders of exchangeable shares on the exercise of the exchange rights attached and that following such exchange, the shares of Stifel common stock so issued will be freely tradeable by holders in the United States; and

•

ensure that the shares of Stifel common stock are listed for trading on the NYSE.

In addition, in determining whether the economic equivalence standards discussed above have been met, the board of directors of Canadian Sub received advice from its financial and legal advisors. The board of directors of Canadian Sub also considered the provisions of the merger agreement that provide that, assuming the Exchangeable Share Amendment is approved, at the effective time of the merger each exchangeable share shall become exchangeable for 0.1364 shares of Stifel common stock (in lieu of one share of Thomas Weisel Partners common stock issuable upon the exchange therefor immediately prior to the effective time of the merger), and that effect an economically equivalent change, from a financial point of view, in the rights of holders of exchangeable shares as compared to the change in the rights of holders of shares of Thomas Weisel Partners common stock effected by the conversion of their shares of Thomas Weisel Partners common stock into the right to receive 0.1364 shares of Stifel common stock as a result of the merger.

Treatment of Thomas Weisel Partners Special Voting Preferred Stock

In the event that the holders of the exchangeable shares approve the Exchangeable Share Amendment, under the merger agreement, at the effective time of the merger the one outstanding share of Thomas Weisel Partners special voting preferred stock will be canceled and automatically converted into one share of Stifel special voting preferred stock. The one share of Stifel special voting preferred stock will entitle the holder to that number of votes equal to the number of shares of Stifel common stock issuable upon exchange of the exchangeable shares outstanding from time to time other than exchangeable shares held by Stifel or any person directly or indirectly controlled by or under common control of Stifel. Provided that the Exchangeable Share Amendment is approved, at the effective time of the merger Stifel will issue one share of Stifel special voting preferred stock and will deliver to the trustee a certificate representing such security. As a result, and pursuant to the operation of the Voting and Exchange Trust Supplement Agreement discussed below, following the effective time of the merger, a holder of exchangeable shares will be entitled to instruct the trustee as to the exercise of the number of votes represented by the number of shares of Stifel common stock issuable upon exchange of the exchangeable shares held by the holder. Holders of exchangeable shares will be entitled to exercise this right at all meetings, and in respect of all matters, at or on which the holders of shares of Stifel common stock are entitled to vote. For this purpose, exchangeable shares held by Stifel, or any person directly or indirectly controlled by or under common control of Stifel, will be excluded. If the holders of the exchangeable shares do not approve the Exchangeable Share Amendment, the share of Thomas Weisel Partners special voting preferred stock will be cancelled as a result of the merger.

C-2

Treatment of Exchangeable Shares

In the event that the holders of the exchangeable shares approve the Exchangeable Share Amendment, the exchangeable shares will not be converted into other securities as part of the merger and will remain outstanding after completion of such transaction. Following the effective time of the merger, the rights, privileges, conditions and restrictions attaching to the exchangeable shares will be substantially equivalent to the rights, privileges, restrictions and conditions attaching to the exchangeable shares immediately prior to the effective time of the merger except that, in effect, each exchangeable share will entitle the holder:

•

to exercise the voting rights summarized above;

•

to receive upon the voluntary or mandatory exchange of the exchangeable shares, however effected, 0.1364 shares of Stifel common stock (plus the amount of any accrued and unpaid dividends on the exchangeable share); and

•

to receive dividends in respect of the exchangeable share that are equal to the dividends paid from time to time in respect of a share of Stifel common stock multiplied by 0.1364.

The holders of exchangeable shares will not receive any fractional shares of Stifel common stock upon any subsequent exchange of exchangeable shares. Instead of any fractional shares, holders of exchangeable shares will be paid, at the time of such exchange, an amount in cash for such fraction of a share calculated by multiplying (A) the fractional share interest to which such holder of exchangeable shares (after taking into account all exchangeable shares exchanged by such holder at the time of exchange) would otherwise be entitled by (B) the average closing sales prices for a share of Stifel common stock for each of the ten consecutive trading days ending with the second complete trading day prior to the effective time of the merger, as such prices are reported on the NYSE Transaction Reporting System.

In the event the holders of the exchangeable shares do not approve the Exchangeable Share Amendment, the merger, which constitutes a change of control pursuant to the terms of the exchangeable shares, will trigger a redemption by Canadian Sub, or an acquisition of the exchangeable shares by TWP Holdings Company (Canada), ULC (should TWP Holdings Company (Canada), ULC exercise its right to acquire the exchangeable shares in lieu of Canadian Sub, which we refer to as the call right). It is expected that TWP Holdings Company (Canada), ULC will exercise the call right whereby each exchangeable share outstanding will be exchanged for one share of Thomas Weisel Partners common stock and, as a result of the merger, holders of exchangeable shares will receive shares of Stifel common stock at the exchange ratio. No fractional shares of Stifel common stock will be issued. Instead, holders of exchangeable shares will be paid an amount in cash for such fraction of a share calculated by multiplying (A) the fractional share interest to which such holder would otherwise be entitled by (B) the average closing sales prices for a share of Stifel common stock for each of the ten consecutive trading days ending with the second complete trading day prior to the effective time of the merger, as such prices are reported on the NYSE Transaction Reporting System.

Voting and Exchange Trust Supplement Agreement and Support Agreement Supplement

At or prior to the effective time of the merger transaction, in the event the holders of the exchangeable shares approve the Exchangeable Share Amendment, Stifel, Thomas Weisel Partners, Canadian Sub and CIBC Mellon Trust Company, as trustee, will enter into a Voting and Exchange Trust Supplement Agreement and Thomas Weisel Partners, Stifel, Canadian Sub and TWP Holdings Company (Canada), ULC will enter into a Support Agreement Supplement, referred to as the Supplements, amending the Voting and Exchange Trust and Support Agreements, respectively. Pursuant to the terms of the Supplements, Stifel will deposit one share of Stifel special voting preferred stock with the trustee and will assume all of the obligations and acquire all of the rights of Thomas Weisel Partners under the Voting and Exchange Trust Agreement and Support Agreement. The Supplements will also provide for the adjustment of the rights of holders of exchangeable shares to provide for the economic equivalence discussed above.

C-3

Certain Material Canadian Federal Income Tax Considerations for Holders of Exchangeable Shares

The following is a summary of certain material Canadian federal income tax considerations under the Income Tax Act (Canada), referred to as the Canadian Tax Act, of the merger that are generally applicable to holders of exchangeable shares who, for purposes of the Canadian Tax Act and at all relevant times, (i) are or are deemed to be resident in Canada, (ii) deal at arm’s length with Thomas Weisel Partners, Canadian Sub, TWP Holdings Company (Canada), ULC and Stifel, (iii) are not affiliated with Thomas Weisel Partners, Canadian Sub, TWP Holdings Company (Canada), ULC or Stifel and (iv) hold their exchangeable shares and certain ancillary rights relating to such exchangeable shares, including the voting and exchange rights under the Voting and Exchange Trust Agreement, as capital property, each such holder referred to as a Canadian Resident Holder.

Exchangeable shares and ancillary rights will generally be considered to be capital property to a Canadian Resident Holder provided the holder thereof does not hold such exchangeable shares or ancillary rights in the course of carrying on a business and has not acquired such exchangeable shares or ancillary rights in an adventure or concern in the nature of trade.

This summary does not apply to a holder: (i) that does not hold exchangeable shares and ancillary rights as capital property, (ii) that is a “financial institution”, as defined in the Canadian Tax Act, to whom the “mark-to-market” rules in the Canadian Tax Act may apply, (iii) an interest in which is a “tax shelter investment”, as defined in the Canadian Tax Act, or (iv) that reports its “Canadian tax results”, as defined in the Canadian Tax Act, in a currency other than the Canadian currency. All such holders should consult their own tax advisers as the following summary does not apply to such holders.

This summary is based on the current provisions of the Canadian Tax Act, the regulations thereunder and the current published administrative practices of the Canada Revenue Agency, all in effect as of the date of this proxy statement/ prospectus. This summary takes into account all specific proposals to amend the Canadian Tax Act and the regulations thereunder publicly announced by or on behalf of the Minister of Finance (Canada) on or before the date of this proxy statement/ prospectus and assumes that such proposals will be enacted in the form proposed. However, no assurance can be given that such proposed amendments will be enacted in the form proposed or at all. This summary does not otherwise take into account or anticipate any changes in law or its administration, whether by judicial, governmental or legislative decision or action, nor does it take into account provincial, territorial or foreign income tax legislation or considerations, which may differ from the Canadian federal income tax considerations described herein.

For purposes of the Canadian Tax Act, all amounts relating to the disposition of exchangeable shares or ancillary rights or to the acquisition of Thomas Weisel Partners common stock or new ancillary rights must be computed in Canadian dollars using the rate of exchange quoted by the Bank of Canada at noon on the relevant date or such other rate of exchange as is acceptable to the Canada Revenue Agency.

This summary is of a general nature only and is not, and is not intended to be, legal or tax advice to any particular holder. Accordingly, each holder of exchangeable shares is urged to consult their own tax advisor as to the particular tax consequences to that holder of the transactions described in this summary.

Consequences in circumstances where the Exchangeable Share Amendment is Approved

Exchangeable Shares

Holders of exchangeable shares will not be considered to have disposed of their exchangeable shares as a result of the merger.

C-4

Ancillary Rights

There is no clear authority as to whether or in which circumstances a foreign merger will result in a holder of rights against a participant in that merger being considered to have disposed of those rights for purposes of the Canadian Tax Act. If holders of exchangeable shares are considered to have disposed of their ancillary rights as a result of the merger, the Voting And Exchange Trust Agreement Supplement and/or the related transactions, and to have acquired new ancillary rights against Stifel, they will be considered to have received proceeds of disposition equal to the fair market value of the new ancillary rights. In such case, they will realize a capital gain to the extent that such proceeds of disposition, net of any reasonable costs of disposition, exceed the adjusted cost base to the holders of the ancillary rights or a capital loss to the extent that such proceeds of disposition, net of any reasonable costs of disposition, are less than the adjusted cost base to the holders of the ancillary rights. The cost to the holders of the new ancillary rights in such circumstances will be equal to the fair market value of the new ancillary rights at the time of the merger. Thomas Weisel Partners and Canadian Sub management are of the view that the new ancillary rights are of only nominal value and that such nominal value does not exceed the value of the ancillary rights at the time that such ancillary rights were acquired by the holders of exchangeable shares. On this basis, no gain should be considered to arise if a holder is considered to have disposed of ancillary rights for new ancillary rights. Such determinations of value are, however, not binding on the Canada Revenue Agency. Should the Canadian Revenue Agency challenge this determination and ultimately succeed in establishing that the new ancillary rights have a value in excess of a nominal amount, then a capital gain may be realized by the holders of the ancillary rights as a result of the merger, as described above.

Consequences in circumstances where the Exchangeable Share Amendment is Not Approved

The following portion of the summary describes certain material Canadian federal income tax considerations under the Canadian Tax Act of the merger to Canadian Resident Holders in circumstances where the Exchangeable Share Amendment is not approved. This portion of the summary assumes that, as a result of the merger, TWP Holdings Company (Canada), ULC will exercise the call right to acquire each exchangeable share held by a Canadian Resident Holder in exchange for one share of Thomas Weisel Partners common stock.

Exchange of Exchangeable Shares with TWP Holdings Company (Canada), ULC for Shares of Thomas Weisel Partners Common Stock

On the exchange of exchangeable shares with TWP Holdings Company (Canada), ULC for shares of Thomas Weisel Partners common stock, a Canadian Resident Holder will realize a capital gain (or a capital loss) equal to the amount by which the proceeds of disposition in respect of such exchangeable shares, net of any reasonable costs of disposition, exceed (or are less than) the adjusted cost base of such exchangeable shares to the Canadian Resident Holder immediately before the exchange. For this purpose, a Canadian Resident Holder’s proceeds of disposition of exchangeable shares will be equal to the fair market value at the time of the exchange of the shares of Thomas Weisel Partners common stock so acquired. The cost to a Canadian Resident Holder of Thomas Weisel Partners common stock acquired in such circumstances will be equal to the fair market value of such Thomas Weisel Partners common stock at the time of the exchange. For the purpose of determining the adjusted cost base at any time to a Canadian Resident Holder of Thomas Weisel Partners common stock it acquires on the exchange, the adjusted cost base of such Thomas Weisel Partners common stock will be determined by averaging the cost of such Thomas Weisel Partners common stock with the adjusted cost base of all other Thomas Weisel Partners common stock, if any, owned by the Canadian Resident Holder as capital property at that time.

Generally, a Canadian Resident Holder is required to include in computing its income for a taxation year half of the amount of any capital gain (a “taxable capital gain”) and must deduct half of the amount of any capital loss (an “allowable capital loss”) realized in a taxation year from taxable capital gains realized by the Canadian Resident Holder in such year, subject to and in accordance with rules contained in the Canadian Tax Act. Any

C-5

allowable capital losses in excess of taxable capital gains for the year of disposition generally may be carried back up to three taxation years or carried forward indefinitely and deducted against taxable capital gains in such other years to the extent and under the circumstances described in the Canadian Tax Act.

Capital gains realized by a shareholder who is an individual or trust, other than certain specified trusts, may give rise to alternative minimum tax under the Canadian Tax Act. A shareholder that is a “Canadian-controlled private corporation,” as defined in the Canadian Tax Act, may be liable to pay an additional refundable tax of 6²/3% on its “aggregate investment income” for the year, which will include an amount in respect of taxable capital gains.

C-6

Annex D

Appraisal Rights Procedures Relating to Thomas Weisel Partners Special Voting Preferred Stock

The holders of Thomas Weisel Partners Group, Inc. (referred to as Thomas Weisel Partners) common stock and exchangeable shares of TWP Acquisition Company (Canada), Inc. are not entitled to any appraisal rights with respect to the merger. If, however, none of the votes attributable to the exchangeable shares are cast by the holder of the Thomas Weisel Partners special voting preferred stock in favor of the approval and adoption of the merger agreement, then the holder of the Thomas Weisel Partners special voting preferred stock would be entitled to demand appraisal of the one share of Thomas Weisel Partners special voting preferred stock upon compliance with the procedures established by Section 262 of the Delaware General Corporation Law and as discussed immediately below.

With respect to the one share of Thomas Weisel Partners special voting preferred stock, Thomas Weisel Partners believes that if CIBC Mellon Trust Company, as trustee under the Voting and Exchange Trust Agreement, exercises any of the votes attached to the Thomas Weisel Partners special voting preferred stock to vote in favor of the proposal to approve and adopt the merger agreement and approve the merger, then the trustee will not be entitled under Section 262 to an appraisal of the Thomas Weisel Partners special voting preferred stock or any interest therein. Accordingly, Thomas Weisel Partners believes that, if the trustee is instructed by at least one holder of exchangeable shares to cast at least one vote at the Thomas Weisel Partners Annual Meeting in favor of the proposal to approve and adopt the merger agreement and approve the merger and the trustee complies with these instructions, the trustee will not be entitled to an appraisal of the one share of Thomas Weisel Partners special voting preferred stock or any interest therein under Section 262.

The following discussion describes the procedures that the holder of the Thomas Weisel Partners special voting preferred stock would have to follow in order to exercise appraisal rights in respect of the single share of the Thomas Weisel Partners special voting preferred stock under Section 262 of the Delaware General Corporation law. This discussion is not a complete statement of the law of appraisal rights and is qualified in its entirety by the full text of Section 262, which is reprinted below. All references in Section 262 and in this summary to a “stockholder” or “holder” are to the stockholder of record of the share of Thomas Weisel Partners special voting preferred stock as to which appraisal rights are asserted.

Under Section 262, if the holder of the Thomas Weisel Partners special voting preferred stock does not cast any of the votes attributable to the exchangeable shares entitled to be cast by such holder in favor of approval and adoption of the merger agreement and otherwise follows the procedures set forth in Section 262, then it will be entitled to have its share of Thomas Weisel Partners special voting preferred stock appraised by the Delaware Court of Chancery and to receive payment in cash of the “fair value” of such share together with interest, if any, as determined by the Court.

Under Section 262, if a merger agreement is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, must notify each of its stockholders who was a holder on the record date for the meeting of shares for which appraisal rights are available, of the availability of appraisal rights, and must include in this notice a copy of Section 262. The proxy statement/prospectus is the notice to the holder of the share of the Thomas Weisel Partners special voting preferred stock required by Section 262 and the text of Section 262 is set out below. If the holder of the share of Thomas Weisel Partners special voting preferred stock wishes to exercise appraisal rights or wishes to preserve its right to do so, it should review the following description and Section 262 carefully. The failure to timely, properly and strictly comply with the required procedures will result in the loss of appraisal rights.

If the holder of the share of the Thomas Weisel Partners special voting preferred stock wishes to exercise appraisal rights it must not cast any of the votes attached to the share of Thomas Weisel Partners special voting preferred stock in favor of the approval and adoption of the merger agreement and must deliver to Thomas

D-1

Weisel Partners prior to the vote on the merger agreement at the Annual Meeting, a written demand for appraisal of the share of the Thomas Weisel Partners special voting preferred stock. This written demand for appraisal is in addition to and separate from any proxy or vote abstaining from or voting against the merger. This demand must reasonably inform Thomas Weisel Partners of the identity of the holder of the share of the Thomas Weisel Partners special voting preferred stock and of the holder’s intent thereby to demand appraisal of the share of the Thomas Weisel Partners special voting preferred stock. The holder of the share of the Thomas Weisel Partners special voting preferred stock wishing to exercise appraisal rights must be the stockholder of record of the share of the Thomas Weisel Partners special voting preferred stock on the date the written demand for appraisal is made and must continue to hold of record the share of the Thomas Weisel Partners special voting preferred stock until the closing of the merger.

Only the stockholder of record of the share of the Thomas Weisel Partners special voting preferred stock is entitled to an appraisal of the share of the Thomas Weisel Partners special voting preferred stock registered in that holder’s name. A demand for appraisal should be executed by or on behalf of the stockholder of record of the share of the Thomas Weisel Partners special voting preferred stock as the holder’s name appears on the stock certificate for the share of the Thomas Weisel Partners special voting preferred stock. If the share of the Thomas Weisel Partners special voting preferred stock is owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, the demand should be executed in that capacity, and if the share of the Thomas Weisel Partners special voting preferred stock is owned of record by more than one owner, as in a joint tenancy or tenancy in common, the demand should be executed by or on behalf of all joint owners. An authorized agent may execute a demand for appraisal on behalf of the stockholder of record of the share of the Thomas Weisel Partners special voting preferred stock. However, in the demand the agent must identify the record owner or owners and expressly disclose that, in executing the demand, the agent is agent for such owner or owners.

All written demands for appraisal should be delivered to Thomas Weisel Partners Group, Inc., One Montgomery Street, San Francisco, California 94104, Attention: Corporate Secretary.

Within 10 days after the effective time of the merger, Thomas Weisel Partners, as the surviving corporation in the merger, will notify the holder of the share of the Thomas Weisel Partners special voting preferred stock of the effective time of the merger if the holder has properly demanded appraisal rights under Section 262 and has not voted in favor of the approval and adoption of the merger agreement.

Within 120 days after the effective time of the merger, but not thereafter, Thomas Weisel Partners, as the surviving corporation in the merger, or the holder of the share of the Thomas Weisel Partners special voting preferred stock if the holder has complied with the requirements of Section 262 and is otherwise entitled to appraisal rights, may file a petition in the Delaware Court of Chancery demanding a determination of the fair value of the share of the Thomas Weisel Partners special voting preferred stock. Thomas Weisel Partners is under no obligation to and has no present intention to file an appraisal petition. Accordingly, it is the obligation of the holder of the share of the Thomas Weisel Partners special voting preferred stock, if the holder wishes to exercise appraisal rights, to file the petition within the time prescribed in Section 262.

The Delaware Court of Chancery may require the holder of the share of Thomas Weisel Partners special voting preferred stock who has demanded an appraisal of the share to submit its stock certificate to the Register in Chancery for notation of the appraisal proceeding. If the holder of the share of Thomas Weisel Partners special voting preferred stock fails to comply with such direction, the Delaware Court of Chancery may dismiss the proceedings.

If a petition for an appraisal is filed timely, after a hearing on the petition, the Delaware Court of Chancery will determine whether the holder of the share of the Thomas Weisel Partners special voting preferred stock is entitled to appraisal rights and will appraise the “fair value” of the share of the Thomas Weisel Partners special voting preferred stock, together with the rate of interest, if any, to be paid upon the amount determined to be the fair value. Under Section 262, fair value does not include any element of value arising from the accomplishment

D-2

or expectation of the merger. If the holder of the share of the Thomas Weisel Partners special voting preferred stock is considering seeking appraisal, it should be aware that the fair value of the share of the Thomas Weisel Partners special voting preferred stock as determined under Section 262 could be more than, the same as or less than the value of the consideration it would receive under the merger agreement if it did not seek appraisal of the share of the Thomas Weisel Partners special voting preferred stock and that an investment banking opinion as to fairness from a financial point of view is not necessarily an opinion as to fair value under section 262. The Delaware Supreme Court has stated that “proof of value by any techniques or methods that are generally considered acceptable in the financial community and otherwise admissible in court” should be considered in the appraisal proceedings.

The costs of the action may be determined by the Delaware Court of Chancery and taxed upon the parties as the Court deems equitable in the circumstances.

The holder of the share of the Thomas Weisel Partners special voting preferred stock who has duly demanded an appraisal in compliance with section 262 will not, after the effective time of the merger, be entitled to vote the share of the Thomas Weisel Partners special voting preferred stock subject to such demand for any purpose.

If the holder properly demands appraisal of the share of the Thomas Weisel Partners special voting preferred stock under section 262 but fails to perfect, or effectively withdraws or loses, his, her or its right to appraisal, as provided in section 262, the share of the Thomas Weisel Partners special voting preferred stock will be converted into the right to receive the consideration receivable for the share of the Thomas Weisel Partners special voting preferred stock under the merger agreement, without interest. The holder of the share of the Thomas Weisel Partners special voting preferred stock will fail to perfect, or effectively lose or withdraw, its right to appraisal if, among other things, no petition for appraisal is filed within 120 days after the effective time of the merger, or if the holder of the share of the Thomas Weisel Partners special voting preferred stock delivers to Thomas Weisel Partners a written withdrawal of its demand for appraisal. The holder of the share of the Thomas Weisel Partners special voting preferred stock may withdraw a demand for appraisal and accept the merger consideration by delivering a written withdrawal of the demand for appraisal to the surviving company, except that any attempt to withdraw made more than 60 days after the effective time of the merger will require written approval of Thomas Weisel Partners, and, once a petition for appraisal is filed, the appraisal proceeding may not be dismissed as to the holder of the share of Thomas Weisel Partners special voting preferred stock without court approval.

Failure to follow the steps required by section 262 for perfecting and pursuing appraisal rights may result in the loss of such rights. If such rights are lost the holder of the share of the Thomas Weisel Partners special voting preferred stock will be entitled to receive the consideration receivable with respect to the Thomas Weisel Partners special voting preferred stock in accordance with the merger agreement.

DELAWARE GENERAL CORPORATION LAW SECTION 262

262 APPRAISAL RIGHTS.

(a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder’s shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word “stockholder” means a holder of record of stock in a stock corporation and also a member of record of a nonstock corporation; the words “stock” and “share” mean and include what is ordinarily meant by those words and also membership or membership interest of a member of a nonstock corporation; and the words “depository receipt” mean a receipt or other instrument issued by a depository representing an interest in one or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

D-3

(b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title), § 252, § 254, § 257, § 258, § 263 or § 264 of this title:

(1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in § 251(f) of this title.

(2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to §§ 251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock anything except:

a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;

b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or held of record by more than 2,000 holders;

c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or

d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph.

(3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under § 253 of this title is not owned by the parent corporation immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable.

(d) Appraisal rights shall be perfected as follows:

(1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for notice of such meeting with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) hereof of this section that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section. Each stockholder electing to demand the appraisal of such stockholder’s shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder’s shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A

D-4

stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or

(2) If the merger or consolidation was approved pursuant to § 228 or § 253 of this title, then either a constituent corporation before the effective date of the merger or consolidation or the surviving or resulting corporation within 10 days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder’s shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder’s shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.

(e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) of this section hereof and who is otherwise entitled to appraisal rights, may commence an appraisal proceeding by filing a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party shall have the right to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) of this section hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder’s written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) of this section hereof, whichever is later. Notwithstanding subsection (a) of this section, a person who is the beneficial owner of shares of such stock held either in a voting trust or by a nominee on behalf of such person may, in such person’s own name, file a petition or request from the corporation the statement described in this subsection.

D-5

(f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder.

(h) After the Court determines the stockholders entitled to an appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding the Court shall determine the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. Unless the Court in its discretion determines otherwise for good cause shown, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, proceed to trial upon the appraisal prior to the final determination of the stockholders entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder’s certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.

(i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court’s decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney’s fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.

(k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions

D-6

payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder’s demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just; provided, however that this provision shall not affect the right of any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation within 60 days after the effective date of the merger or consolidation, as set forth in subsection (e) of this section.

(l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.

1. Voting Provisions.

(a) Agreement to Vote Shares of Parent Common Stock. The Stockholder hereby agrees that during the Term (as defined in Section 3 below) of this Agreement to vote or cause to be voted all shares of Company Common Stock (and in the case of any Exchangeable Shares owned by the Stockholder, to instruct the Voting Trustee to cast votes in respect of all of such Exchangeable Shares) identified on Schedule I as owned of record and/or beneficially (as defined in Rule 13d-3 of the Exchange Act of 1934, as amended) by the Stockholder (such Stockholder’s shares of Company Common Stock and/or Exchangeable Shares, the “Shares”) (a) in favor of the Merger and (b) to approve the Merger Agreement (to be executed and delivered concurrently herewith in substantially the form attached hereto) and the transactions contemplated thereunder at every meeting of

As of the date hereof, the Stockholder, with respect to any Company Common Stock held by the Stockholder, has sole voting power, and with respect to any Exchangeable Shares held by the Stockholder, sole power to instruct the Voting Trustee to vote the Voting Share with respect to such Exchangeable Shares and sole power to issue instructions to the Voting Trustee with respect to such Exchangeable Shares with respect to the matters set forth in Section 1 hereof, and sole power of disposition, sole power of conversion and sole power to agree to all of the matters set forth in this Agreement, in each case with respect to all of the Shares, with no limitations, qualifications or restrictions on such rights, subject only to applicable securities laws and the terms of this Agreement.

(c) No Conflicts. No filing with, and no permit, authorization, consent or approval of, any Governmental Authority is necessary for the execution of this Agreement by the Stockholder and the consummation by such Stockholder of the transactions contemplated hereby. None of the execution and delivery of this Agreement by such Stockholder, the consummation by the Stockholder of the transactions contemplated hereby or compliance by the Stockholder with any of the provisions hereof shall (A) conflict with or result in any breach of any applicable documents to which such Stockholder is a party, or (B) violate any order, writ, injunction, decree, judgment, order, statute, rule or regulation applicable to such Stockholder in each case in a manner that would adversely affect the Stockholder’s ability to perform any of its obligations hereunder.

Item 20.

Indemnification of Officers and Directors

The following is a summary of Section 145 of the General Corporation Law of the State of Delaware (the “DGCL”).

Subject to restrictions contained in the DGCL, a corporation may indemnify any person, who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorney’s fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection therewith if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, and, in connection with any criminal action or proceeding, had no reasonable cause to believe that such person’s conduct was unlawful. A present or former director or officer who is successful on the merits or otherwise in any suit or matter covered by the indemnification statute, shall be indemnified and indemnification is otherwise authorized upon a determination that the person to be indemnified has met the applicable standard of conduct required. Such determination shall be made by a majority vote of the board of directors who were not parties to such action, suit or proceeding, even though less than a quorum, a committee of such directors designated by majority vote of such directors, even though less than a quorum, or if there are no such directors, or if such directors so direct, by special independent counsel in a written opinion, or by the stockholders. Expenses incurred in defense may be paid in advance upon receipt by the corporation of a written undertaking by or on behalf of the recipient to repay such amount if it is ultimately determined that the recipient is not entitled to indemnification under the statute. The indemnification provided by statute is not exclusive of any other rights to which those seeking indemnification may be entitled under any by-law, agreement, vote of stockholders or disinterested directors or otherwise, and shall inure to the benefit of the heirs, executors and administrators of such person. Insurance may be purchased on behalf of any person entitled to indemnification by the corporation against any liability asserted against him or her and incurred in an official capacity regardless of whether the person could be indemnified under the statute. References to the corporation include all constituent corporations absorbed in a consolidation or merger as well as the resulting corporation, and anyone seeking indemnification by virtue of acting in some capacity with a constituent corporation would stand in the same position as if such person had served the resulting or surviving corporation in the same capacity.

The Registrant’s Restated Certificate of Incorporation, as amended, provides generally that a director shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any transaction from which the director derived an improper personal benefit.

Section 6.4 of the Registrant’s Amended and Restated Bylaws provides for indemnification by the Registrant of each person who is or was a director, officer or employee of the Registrant (or is or was serving as a director, officer or employee of any other enterprise at the request of the Registrant) to the full extent authorized by law. Certain of the directors also have indemnification agreements with the Registrant which provide for indemnification to the full extent permitted by the DGCL or by any amendment thereof or any other statutory provisions authorizing or permitting indemnification.

In addition, the DGCL authorizes the Registrant to purchase insurance for its directors and officers insuring them against certain risks as to which the Registrant may be unable lawfully to indemnify them. The Registrant has purchased insurance coverage for its directors and officers as well as insurance coverage to reimburse itself for potential costs of corporate indemnification of its directors and officers.

Undertakings.

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933.

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in

II-2

the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) If the registrant is relying on Rule 430B (§230.430B of this chapter):

A. Each prospectus filed by the registrant pursuant to Rule 424(b)(3)shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

B. Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; or

(ii) If the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

II-3

(5) That, for the purpose of determining any liability under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

(d) The registrant undertakes that every prospectus: (i) that is filed pursuant to paragraph (c) immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(e) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers, and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

II-4

(f) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(g) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
