     Greenhill & Co., Inc. (which we refer to as “Greenhill” or “we” in this proxy statement) is soliciting proxies for use at the annual meeting of stockholders to be held on April 20, 2011, and at any adjournment or postponement of the meeting. This proxy statement and the enclosed proxy card are first being mailed or given to stockholders on or about March 11, 2011.
QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING AND VOTING
What is the purpose of the meeting?
     At our annual meeting, stockholders will act upon the matters outlined in the Notice of Annual Meeting of Stockholders. These include the election of directors and ratification of the selection of our independent auditors as well as advisory votes on our executive compensation and the frequency of future advisory votes on our executive compensation. Also, management will report on matters of current interest to our stockholders and respond to questions.
Who is entitled to vote at the meeting?
     The Board has set March 1, 2011, as the record date for the annual meeting. If you were a stockholder of record at the close of business on March 1, 2011, you are entitled to vote at the meeting. As of the record date, 29,658,014 shares of common stock were issued and outstanding and, therefore, eligible to vote at the meeting.
What are my voting rights?
     Holders of our common stock are entitled to one vote per share. Therefore, a total of 29,658,014 votes are entitled to be cast at the meeting. There is no cumulative voting.
How many shares must be present to hold the meeting?
     In accordance with our bylaws, holders of a majority of the outstanding shares of common stock entitled to vote at a meeting of stockholders must be present at the meeting in order to hold the meeting and conduct business. This is called a quorum. Shares are counted as present at the meeting if:
    you are present and vote in person at the meeting;
 
    you have properly submitted a proxy card by mail; or
 
    you have properly voted via the Internet.
How do I submit my proxy vote?
     If you are a stockholder of record, you can give a proxy to be voted at the meeting by completing, signing and mailing the enclosed proxy card.
     If you wish to vote using a proxy, please return your signed proxy card to us before the annual meeting.
     If you hold your shares in “street name,” you must vote your shares in the manner prescribed by your broker, bank, trust or other nominee. Your broker, bank, trust or other nominee has enclosed or otherwise provided a voting instruction card for you to use in directing the broker, bank, trust or nominee how to vote your shares.
What is the difference between a stockholder of record and a “street name” holder?
     If your shares are registered directly in your name, you are considered the stockholder of record with respect to those shares.
     If your shares are held in a stock brokerage account or by a broker, bank, trust or other nominee, then the broker, bank, trust or other nominee is considered to be the stockholder of record with respect to those shares. However, you still are considered the beneficial owner of those shares, and your shares are said to be held in “street name.” Street name holders generally cannot vote their shares directly and must instead

Table of Contents

instruct the broker, bank, trust or other nominee how to vote their shares using the method described above under “How do I submit my proxy vote?”
What does it mean if I receive more than one proxy card?
     If you receive more than one proxy card, it means that you hold shares registered in more than one account. To ensure that all of your shares are voted, sign and return each proxy card you receive.
How do I vote via the Internet?
     Internet voting information is provided on the proxy card. A control number, which is the number located below the account number on the proxy card, is designated to verify a stockholder’s identity and allow the stockholder to vote the shares and confirm that the voting instructions have been recorded properly. If you vote via the Internet, please do not return a signed proxy card. Stockholders who hold their shares through a bank of broker can vote via the Internet if that option is offered by the bank or broker.
Can I vote my shares in person at the meeting?
     If you are a stockholder of record, you may vote your shares in person at the meeting by completing a ballot at the meeting. Even if you currently plan to attend the meeting, we recommend that you also submit your proxy as described above so that your vote will be counted if you later decide not to attend the meeting. If you submit your vote by proxy and then decide to vote in person at the annual meeting, the vote you submit at the meeting will override your proxy vote.
     If you are a street name holder, you may vote your shares in person at the meeting only if you obtain and bring to the meeting a signed letter or other proxy from your broker, bank, trust or other nominee giving you the right to vote the shares at the meeting.
What vote is required for the election of directors or for a proposal to be approved?
     The approval of a plurality of the votes of the shares present at the meeting is required for the election of directors. The affirmative vote of the holders of a majority of the outstanding shares of common stock present in person or represented by proxy and entitled to vote at the annual meeting is required to ratify the selection of our independent auditors.
How are votes counted?
     You may either vote “FOR” or “WITHHOLD” authority to vote for each nominee for the Board of Directors. For the advisory vote on the frequency of future advisory compensation, you may choose among the following alternatives: “EVERY YEAR,” “EVERY TWO YEARS,” “EVERY THREE YEARS” or “ABSTAIN.” You may vote “FOR,” “AGAINST” or “ABSTAIN” on the other proposals. The advisory votes are not binding on the Board of Directors, but we value your vote and will consider the results carefully.
     If you submit your proxy or vote via the Internet but abstain from voting on one or more matters, your shares will be counted as present at the meeting for the purpose of determining a quorum. Your shares also will be counted as present at the meeting for the purpose of calculating the vote on the particular matter with respect to which you abstained from voting or withheld authority to vote.
     If you abstain from voting on a proposal, your abstention has the same effect as a vote against that proposal.
     The New York Stock Exchange permits a member broker who holds shares in street name for customers to use its discretion to vote on “routine matters” but member brokers cannot vote on the election of directors or on the executive compensation-related proposals if the broker has not received instructions from the beneficial owner of the shares. We therefore urge you to give voting instructions to your broker on all proposals.

Table of Contents

How does the Board recommend that I vote?
     The Board of Directors recommends a vote:
    FOR all of the nominees for director;
 
    FOR the advisory resolution to approve our executive compensation;
 
    FOR a frequency of every THREE years for future stockholder advisory votes on our executive compensation; and
 
    FOR the ratification of the selection of Ernst & Young LLP as Greenhill’s independent auditors for the year ending December 31, 2011.
What if I do not specify how I want my shares voted?
     If you submit a signed proxy card or vote via the Internet but do not specify how you want to vote your shares, we will vote your shares:
    FOR all of the nominees for director;
 
    FOR the advisory resolution to approve our executive compensation;
 
    FOR a frequency of every THREE years for future stockholder advisory votes on our executive compensation; and
 
    FOR the ratification of the selection of Ernst & Young LLP as Greenhill’s independent auditors for the year ending December 31, 2011.
Can I change my vote after submitting my proxy?
     Yes. Whether you vote by mail or via the Internet, you may revoke your proxy and change your vote at any time before your proxy is voted at the annual meeting, in any of the following ways:
    By sending a written notice of revocation to the Secretary of Greenhill;
 
    By submitting a later-dated proxy to the Secretary of Greenhill;
 
    By voting via the Internet at a later time; or
 
    By voting in person at the meeting.
Will my vote be kept confidential?
     Yes. We have procedures to ensure that, regardless of whether stockholders vote by mail, via the Internet or in person, (1) all proxies, ballots and voting tabulations that identify stockholders are kept permanently confidential, except as disclosure may be required by federal or state law or expressly permitted by a stockholder; and (2) voting tabulations are performed by an independent third party.
How can I attend the meeting?
     You may be asked to present valid picture identification, such as a driver’s license or passport, before being admitted to the meeting. You also will need proof of ownership to be admitted to the meeting. A recent brokerage statement or letter from your broker, bank, trust or other nominee are examples of proof of ownership.
     Please let us know if you plan to attend the meeting when you return your proxy, by marking the attendance box on the proxy card.

Who pays for the cost of proxy preparation and solicitation?
     Greenhill pays for the cost of proxy preparation and solicitation, including the reasonable charges and expenses of brokerage firms, banks, trusts or other nominees for forwarding proxy materials to street name holders.
     We are soliciting proxies primarily by mail. In addition, our directors, officers and regular employees may solicit proxies by telephone or facsimile or personally. These individuals will receive no additional compensation for their services other than their regular compensation.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
     Section 16(a) of the Securities Exchange Act of 1934 requires our executive officers, directors and beneficial owners of more than 10% of our common stock to file initial reports of ownership and reports of changes in ownership of our securities with the Securities and Exchange Commission. Such persons are required to furnish us with copies of these reports. We believe that all Section 16(a) filing requirements applicable to our executive officers and directors for 2010 were satisfied.

ITEM 1 — ELECTION OF DIRECTORS
     The number of directors currently serving on our Board of Directors (which we also refer to as our “Board”) is six. Each director who is elected will serve a one-year term. Each of the nominees has agreed to serve as a director if elected. If, for any reason, any nominee becomes unable to serve before the election, the persons named as proxies will vote your shares for a substitute nominee selected by the Board of Directors.
     The nominees for election as director have provided the following information about themselves.
     Robert F. Greenhill, 74, our founder, has served as our Chairman since the time of our founding in 1996 and served as our Chief Executive Officer between 1996 and October 2007. Mr. Greenhill was a member of our Management Committee since its formation in January 2004 until October 2007. In addition, Mr. Greenhill has been a director of Greenhill & Co., Inc. since its incorporation in March 2004. Prior to founding and becoming Chairman of Greenhill, Mr. Greenhill was chairman and chief executive officer of Smith Barney Inc. and a member of the board of directors of the predecessor to the present Travelers Corporation (the parent of Smith Barney) from June 1993 to January 1996. From January 1991 to June 1993, Mr. Greenhill was president of, and from January 1989 to January 1991, Mr. Greenhill was a vice chairman of, Morgan Stanley Group, Inc. Mr. Greenhill joined Morgan Stanley in 1962 and became a partner in 1970. In 1972, Mr. Greenhill directed Morgan Stanley’s newly-formed mergers and acquisitions department. In 1980, Mr. Greenhill was named director of Morgan Stanley’s investment banking division, with responsibility for domestic and international corporate finance, mergers and acquisitions, merchant banking, capital markets services and real estate. Also in 1980, Mr. Greenhill became a member of Morgan Stanley’s management committee. We chose to nominate Mr. Greenhill as a director because he is the founder of our firm and has nearly fifty years of experience in our industry.
     Scott L. Bok, 51, has served as Chief Executive Officer since April 2010, served as Co-Chief Executive Officer between October 2007 and April 2010, and served as our U.S. President between January 2004 and October 2007. He has also served as a member of our Management Committee since its formation in January 2004. In addition, Mr. Bok has been a director of Greenhill & Co., Inc. since its incorporation in March 2004. Mr. Bok joined Greenhill as a Managing Director in February 1997. Before joining Greenhill, Mr. Bok was a managing director in the mergers, acquisitions and restructuring department of Morgan Stanley & Co., where he worked from 1986 to 1997, based in New York and London. From 1984 to 1986, Mr. Bok practiced mergers and acquisitions and securities law in New York with Wachtell, Lipton, Rosen & Katz. Mr. Bok is a member of the board of directors of Iridium Communications Inc. (f/k/a GHL Acquisitions Corp.). Mr. Bok served as Chief Executive Officer and Chairman of the Board of Directors of GHL Acquisition Corp. from 2007 to 2009. He has also served as a member of the board of directors of Heartland Payment Systems (2001 — 2005) and Republic Group Insurance (2003 — 2007). We chose to nominate Mr. Bok as a director because he serves as our Chief Executive Officer and has more than twenty years of experience in our industry.
     John C. Danforth, 74, has served on our Board of Directors since February 2005. He served as the United States Representative to the United Nations between July 2004 and January 2005 and, except during his service at the United Nations, has been a partner in the law firm of Bryan Cave LLP since 1995. He served in the United States Senate from 1976 to 1995. Senator Danforth is a member of the board of directors of Cerner Corporation. He is ordained to the clergy of the Episcopal Church. We chose to nominate Mr. Danforth as a director because he was personally known to members of our management, who respected Mr. Danforth’s high integrity, sense of ethics and experience with government matters; we believe that his long record of outstanding public service enables Mr. Danforth to bring incremental perspectives to our Board.

     Steven F. Goldstone, 65, has served on our Board of Directors since July 2004. He currently manages Silver Spring Group, a private investment firm. From 1995 until his retirement in 2000, Mr. Goldstone was chairman and chief executive officer of RJR Nabisco, Inc. (which was subsequently named Nabisco Group Holdings following the reorganization of RJR Nabisco, Inc.). Prior to joining RJR Nabisco, Inc., Mr. Goldstone was a partner at Davis Polk & Wardwell, a law firm in New York City. He is also the non-executive Chairman of ConAgra Foods, Inc. and a member of the board of directors of Merck & Co. Mr. Goldstone served as a member of the board of directors of Trane, Inc. (f/k/a American Standards Companies, Inc.) from 2002 until 2008. We chose to nominate Mr. Goldstone as a director because he was personally known to several members of our management, who respected Mr. Goldstone’s high integrity and business acumen. We believe Mr. Goldstone’s past experience in a service industry similar to ours as well as his experience as the leader of a complex publicly traded company enables Mr. Goldstone to provide valuable experience to our Board.
     Stephen L. Key, 67, has served on our Board of Directors since May 2004. Since 2003, Mr. Key has been the sole proprietor of Key Consulting, LLC. From 1995 to 2001, Mr. Key was the Executive Vice President and Chief Financial Officer of Textron Inc., and from 1992 to 1995, Mr. Key was the Executive Vice President and Chief Financial Officer of ConAgra, Inc. From 1968 to 1992, Mr. Key worked at Ernst & Young, serving in various capacities, including as the Managing Partner of Ernst & Young’s New York Office from 1988 to 1992. Mr. Key is a Certified Public Accountant in the State of New York. Mr. Key is also a member of the board of directors of Forward Industries, Inc. and 1-800-Contacts, Inc. Mr. Key served as a member of the board of directors of Sitel, Inc. from 2007 until 2008. We chose to nominate Mr. Key as a director because he was personally known to several members of our management, who respected Mr. Key’s high integrity and financial expertise. We believe Mr. Key’s deep accounting experience and his previous management experience at several public companies adds significant support both to the Board of Directors and the management team in considering accounting, finance and related matters.
     Robert T. Blakely, 69, has served on our Board of Directors since April 2009. Since 2008, Mr. Blakely has served as the President of Performance Enhancement Group, a position he previously held from 2002 to 2003.

From 2003 to 2006, Mr. Blakely served as Executive Vice President and Chief Financial Officer of MCI. From 1999 to 2002 he served as Executive Vice President and Chief Financial Officer of Lyondell Chemical. From 1981 to 1999 he served as Executive Vice President and Chief Financial Officer of Tenneco, Inc. From 1971 to 1981 Mr. Blakely was with Morgan Stanley. Mr. Blakely is a member of the board of directors of Westlake Chemical Corporation, Natural Resource Partners L.P. and Ally Financial Inc. (formerly GMAC, Inc.). Mr. Blakely is Vice Chairman of the Board of Trustees of the Financial Accounting Federation, the oversight body for the Financial Accounting Standards Board. We chose to nominate Mr. Blakely as a director because he was personally known to several members of our management, who respected Mr. Blakely’s high integrity and financial expertise. We believe Mr. Blakely’s financial expertise and previous management experience at public companies in several different industries, including the financial services industry, brings additional perspectives to the oversight of our business.
     The Board of Directors recommends a vote FOR the election of all of the director nominees. Proxies will be voted FOR the election of the nominees unless otherwise specified.

ITEM 2 — ADVISORY RESOLUTION ON EXECUTIVE COMPENSATION
     In accordance with the recently adopted Section 14A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which was added under the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank”), we are asking stockholders to approve an advisory resolution on the our executive compensation as reported in this proxy statement.
Summary of our Executive Compensation
     Our executive compensation programs are designed to attract, motivate and retain executive leadership necessary for Greenhill to achieve long-term success and increase stockholder value, taking into account the critical importance of human capital to our business. We are committed to utilizing the executive compensation program to reinforce our ownership culture and broaden employee ownership over time.
     The components of our compensation for our executive officers and other professional employees have remained unchanged since the time of our initial public offering in 2004:
    a competitive base salary, and
 
    incentive compensation, based on our operating performance and each individual’s contribution to revenue as well as the development of our client base and market position and, where applicable, management, generally consisting of
    an annual incentive compensation in the form of cash, and/or
 
    long-term incentive compensation in the form of restricted stock units with a five year vesting period.
     The relative percentage of these components is not fixed, giving the Compensation Committee the flexibility to adjust the mix of compensation as circumstances change. This year, none of our executive officers will receive any annual incentive compensation in the form of cash and the long term incentive compensation granted in the form of restricted stock units will vest in its entirety on January 1, 2016, subject to continued employment until the vesting date. We believe that the lack of turn-over among our executive officers together with our stockholder returns since our IPO confirm the effectiveness of our compensation practices. Our total stockholder return over the 1-, 3-, and 5-year periods was 4.4%, 32.9%, and 62.3%, respectively. We encourage our stockholders to read our Compensation Discussion and Analysis in its entirety.
     We are asking our stockholders to approve the following advisory resolution at our 2011 annual meeting:
          “RESOLVED, that the stockholders of Greenhill & Co., Inc. (the “Company”) approve, on an advisory basis, the compensation of the Company’s named executive officers as disclosed pursuant to Item 402 of Regulation S-K, which disclosure includes the Compensation Discussion and Analysis, the tabular disclosure regarding such compensation and the accompanying narrative disclosure set forth in the proxy statement for the Company’s 2011 annual meeting of stockholders.”
          This advisory resolution, commonly referred to as “say-on-pay”, is not binding on the Compensation Committee or the Board of Directors. Although non-binding, the Board and the Compensation Committee will carefully review and consider the voting results when evaluating our executive compensation program.

     The Board of Directors recommends that you vote FOR the approval of the advisory resolution to approve our executive compensation.
ITEM 3 — ADVISORY VOTE ON THE FREQUENCY OF FUTURE ADVISORY VOTES ON OUR EXECUTIVE COMPENSATION
     In accordance with the recently adopted Dodd-Frank Act, we are asking stockholders to vote on whether future advisory votes on our executive compensation should occur every year, every two years, or every three years. Stockholders may also abstain from voting.
     After careful consideration, the Board of Directors recommends that future advisory votes on our executive compensation occur every three years. We believe this frequency is appropriate, among other reasons, because:
    our compensation programs do not change significantly from year to year;
 
    our compensation programs do not contain any significant risk to our stockholders; and
 
    a longer period is necessary to assess the effectiveness of our compensation programs, in light of the long vesting period for our long-term incentive awards.
     Given that our compensation is comprised of several components which are designed to work together over a five year time period and which are assessed by the Compensation Committee over a multi-year horizon, annual adjustments must be made with these long-term goals in mind; we do not believe frequent, short term changes will be in the best interests of our stockholders. In addition, while a more frequent vote on executive compensation will indicate that our stockholders have concerns about our compensation practices, it will not give us specific information about those concerns. We believe other available tools will provide more meaningful mechanisms for stockholders to state their views about specific aspects of our executive compensation program and policies: we are actively engaged in dialogues with our stockholders on a number of topics, and those whom we do not speak with on a regular basis can use the procedures set out in this proxy statement under “Information Regarding the Board of Directors and Corporate Governance — Procedures for Contacting the Board of Directors” to send letters to our directors to express their views.
     We believe that an advisory vote on executive compensation every three years will reflect the right balance of considerations in the normal course and foster a longer-term view of the effectiveness of our compensation program. While this vote on the frequency of future advisory votes on our executive compensation is not binding on the Board of Directors and it is possible that none of the alternatives receives a majority of votes, we will periodically reassess our views on frequency and can provide for an advisory vote on executive compensation on a more frequent basis if changes in our compensation programs or other circumstances suggest that such a vote would be appropriate.
     Stockholders will be able to specify one of four choices on the proxy card: three years, two years, one year or abstain.
     The Board of Directors recommends that you vote to conduct future advisory votes on our executive compensation every THREE years.

ITEM 4 — RATIFICATION OF SELECTION OF AUDITORS
     The Audit Committee of our Board of Directors has selected Ernst & Young LLP to continue to serve as our independent auditors for the year ending December 31, 2011. While it is not required to do so, our Board of Directors is submitting the selection of Ernst & Young LLP for ratification in order to ascertain the views of our stockholders on this appointment. If the selection is not ratified, our Audit Committee will reconsider its selection.
     Representatives of Ernst & Young LLP are expected to be present at the annual meeting, will be available to answer stockholder questions and will have the opportunity to make a statement if they desire to do so.
     The Board of Directors recommends that you vote FOR ratification of the selection of Ernst & Young LLP as the independent auditors of Greenhill and our subsidiaries for the year ending December 31, 2011. Proxies will be voted FOR ratifying this selection unless otherwise specified.
INFORMATION REGARDING THE BOARD OF DIRECTORS AND CORPORATE GOVERNANCE
     The Board of Directors conducts its business through meetings of the Board and the following standing committees: Audit, Compensation, and Nominating and Governance. Each of the standing committees has adopted and operates under a written charter, all of which are available on our Web site at www.greenhill.com. Other corporate governance documents also are available on our Web site at the same address, including our Corporate Governance Guidelines, our Code of Business Conduct and Ethics and our Related Person Transaction Policy. The Guidelines, the Code and the Related Person Transaction Policy are also available in print to any shareholder who requests them.
Director Independence
     Under applicable New York Stock Exchange listing standards, a majority of the Board of Directors must be independent, and no director qualifies as “independent” unless the Board of Directors affirmatively determines that the director has no material relationship with Greenhill. In connection with this independence determination, the Board considered transactions and relationships between each director or director nominee or any member of his or her immediate family and Greenhill and its subsidiaries and affiliates, including those reported under “Certain Relationships and Related Transactions” below. The Board also examined transactions and relationships between directors and our director nominee or their affiliates and members of Greenhill’s senior management or their affiliates. The purpose of this review was to determine whether any such relationships or transactions were inconsistent with a determination that the director or director nominee is independent.
     The Board determined that none of Messrs. Danforth, Goldstone, Key or Blakely:
    had any material relationship with Greenhill (other than as directors)
 
    had any material relationship, either directly or as a partner, shareholder or officer of another organization that has a relationship with Greenhill
 
    is an employee or has an immediate family member who is or has in the last three years been an executive officer of Greenhill
 
    receives, or has an immediate family member who receives, more than $120,000 in direct compensation from Greenhill (other than director and committee fees)
 
    is affiliated with or employed by, or has an immediate family member who is or has been within the past three years a partner of or employee of the Greenhill audit team or, a present or former internal or external auditor of Greenhill

11


Table of Contents

    is employed or has an immediate family member who is employed as an executive officer of another company where any of Greenhill’s present executives serve on the compensation committee
 
    is an executive officer of a company that makes payment to or receives payments from Greenhill for property or services in an amount which, in any single fiscal year, exceeds the greater of $1 million or 2% of such other company’s consolidated gross revenues
 
    is an executive officer of any charitable organization to which Greenhill has contributed an amount in any single fiscal year in excess of $1 million or 2% of the consolidated gross revenues of such charitable organization.
     As a result of this review the Board affirmatively determined that each of our non-employee directors (Robert T. Blakely, John C. Danforth, Steven F. Goldstone, and Stephen L. Key) is “independent” as that term is defined in the applicable New York Stock Exchange listing standards. Messrs. Greenhill and Bok cannot be considered independent directors because of their employment at Greenhill.
Meetings of the Independent Directors
     In addition to the committees of the Board of Directors described above, our non-employee directors meet regularly in executive sessions in which our employee directors (Messrs. Greenhill and Bok) and other members of management do not participate. The independent directors take turns serving as the presiding director of these executive sessions.
Committees of the Board
     Audit Committee
Members:
Stephen L. Key (Chairman)
Robert T. Blakely
John C. Danforth
     The Audit Committee is a separate committee established in accordance with Rule 10A-3 under the Securities Exchange Act of 1934. The Board of Directors has determined that all members of the Audit Committee are “independent” as that term is defined in the applicable New York Stock Exchange listing standards and regulations of the Securities and Exchange Commission and that all members are financially literate as required by the applicable New York Stock Exchange listing standards. The Board of Directors also has determined that all members of the Audit Committee have the accounting or related financial expertise required by the applicable New York Stock Exchange listing standards and that Mr. Key is an “audit committee financial expert” as defined by applicable regulations of the Securities and Exchange Commission. While we do not have a policy that limits the number of public company audit committees on which the members of our Audit Committee may serve, none of the members of our Audit Committee other than Mr. Blakely currently serve on more than three such audit committees. Mr. Blakely currently serves on the audit committees of four public companies, including Greenhill. Our Board of Directors has discussed with Mr. Blakely the time and effort required to be devoted by Mr. Blakely to his service on these committees and has affirmatively determined that such services do not impair Mr. Blakely’s ability to serve as an effective member of Greenhill’s Audit Committee.
     The Audit Committee’s purpose is to oversee the independent auditor’s qualifications, independence and performance, the integrity of our financial statements, the performance of our internal audit function and independent auditors and compliance with legal and regulatory requirements. The Audit Committee has sole authority to retain and terminate the independent auditors

12


Table of Contents

and is directly responsible for the compensation and oversight of the work of the independent auditors. The Audit Committee reviews and discusses with management and the independent auditors the annual audited and quarterly financial statements, reviews the integrity of the financial reporting processes, both internal and external, and prepares the Audit Committee Report included in the proxy statement in accordance with the rules and regulations of the Securities and Exchange Commission. The Audit Committee has adopted and operates under a written charter, which is available on our Web site at www.greenhill.com. The Audit Committee met five times during 2010. In addition, the SEC Subcommittee of the Audit Committee, which is responsible for reviewing periodic reports of Greenhill filed with the SEC, met three times during 2010.
     Compensation Committee
Members:
Steven F. Goldstone (Chairman)
Robert T. Blakely
Stephen L. Key
     The Board of Directors has determined that all members of the Compensation Committee are “independent” as that term is defined in applicable New York Stock Exchange listing standards. The Compensation Committee oversees our compensation and benefits policies generally, evaluates senior executive performance, oversees and sets compensation for our senior executives and reviews management’s succession plan. The Compensation Committee evaluates our compensation philosophy, goals and objectives generally, and it approves corporate goals related to the compensation of our senior executives (including the chief executive officer), approves compensation and compensatory arrangements applicable to our other executive officers based on our compensation goals and objectives. See “Executive Compensation — Compensation Discussion and Analysis” for more information on the Compensation Committee’s role in determining compensation. In addition, the Committee is responsible for reviewing and recommending the establishment of broad-based incentive compensation, equity-based, retirement or other material employee benefit plans, and for discharging any duties under the terms of our equity incentive plan. The Compensation Committee has adopted and operates under a written charter, which permits the Compensation Committee to delegate its authority to subcommittees of the Chairman of the Compensation Committee when it deems appropriate and in the best interests of Greenhill. The charter is available on our Web site at www.greenhill.com. The Compensation Committee met three times during 2010.
     Nominating and Governance Committee
Members:
Robert T. Blakely (Chairman)
Steven F. Goldstone
Stephen L. Key
     The Board of Directors has determined that all members of the Nominating and Governance Committee are “independent” as that term is defined in applicable New York Stock Exchange listing standards. The Nominating and Governance Committee identifies and recommends individuals qualified to become members of the Board of Directors and recommends to the Board sound corporate governance principles and practices for Greenhill. In particular, the Committee assesses the independence of all Board members, identifies and evaluates candidates for nomination as directors, recommends the slate of director nominees for election at the annual meeting of stockholders and to fill vacancies between annual meetings, recommends qualified members of the Board for membership on committees, oversees the director orientation and continuing education programs, reviews the Board’s committee structure, reviews and assesses the adequacy of our Corporate Governance Guidelines, evaluates the annual evaluation process for the Board and Board committees and is charged with

13


Table of Contents

overseeing our Related Person Transaction Policy. The responsibilities of the Nominating and Governance Committee are set forth in the Nominating and Governance Committee Charter, which is available on our Web site at www.greenhill.com. The Nominating and Governance Committee met two times during 2010.
Meeting Attendance
     Our Corporate Governance Guidelines provide that our directors are expected to attend meetings of the Board and of the committees on which they serve. We do not have a policy requiring directors to attend our annual meeting of stockholders. All of our directors except Mr. Borrows (who has since resigned from our Board) attended the annual meeting of stockholders in 2010, and all of our directors attended at least 75% of the Board and committee meetings on which the directors served.
Procedures for Contacting the Board of Directors
     The Board has established a process for stockholders and other interested parties to send written communications to the Board or to individual directors. Such communications may be made anonymously. Such communications should be sent by U.S. mail to the Board of Directors, c/o Greenhill, 300 Park Avenue, New York, New York, 10022 (attention: General Counsel). The communications will be collected by the Secretary and delivered, in the form received and if so addressed, to a specified director, the independent directors or the Audit Committee or its Chairman. Items that are unrelated to a director’s duties and responsibilities as a Board member may be excluded by the Secretary, including solicitations and advertisements, junk mail and resumes.
Procedures for Selecting and Nominating Director Candidates
     In evaluating the appropriate characteristics of candidates for service as a director, the Nominating and Governance Committee takes into account many factors. At a minimum, director candidates must demonstrate high standards of ethics, integrity and professionalism, independence, sound judgment, community leadership and meaningful experience in business, law or finance or other appropriate endeavor. In addition, the candidates must be committed to representing the long-term interests of our stockholders. In addition to these minimum qualifications, the Committee also considers other factors it deems appropriate based on the current needs of the Board, including specific business and financial expertise currently desired on the Board, experience as a director of a public company and diversity. The Committee does not have any formal diversity policy. With these factors and characteristics in mind, the Committee will generally begin its search by seeking nominations from existing members of the Board and management. The Committee will also reassess the qualifications of a director, including the director’s past contributions to the Board and the director’s attendance and contributions at Board and committee meetings, prior to recommending a director for reelection to another term.
     Our Board of Directors has adopted procedures by which stockholders may recommend nominees to the Board. The Nominating and Governance Committee will consider any director candidate recommended by shareholders in accordance with the procedures set out in our bylaws and applicable law on the same basis as it considers other director candidates. Stockholders may also submit a letter and relevant information about the candidate to the Secretary at Greenhill & Co., Inc., 300 Park Avenue, New York, New York 10022.
Director and Officer Indemnification
     We have entered into agreements that provide indemnification to our directors, officers and all 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 amended and restated certificate of incorporation.

Board Leadership Structure and Role in Risk Oversight
     The Chairman of our Board of Directors, Robert F. Greenhill, is the founder of Greenhill and has previously served as its Chief Executive Officer. In 2007, Mr. Greenhill relinquished the position as Chief Executive Officer. At that time, the Board of Directors determined that it was in the best interests of our stockholders for Mr. Greenhill to continue to serve as Chairman of the Board, given the depth of his experience with our firm and our industry. The independent members of our Board of Directors have not chosen to appoint a “lead independent director”. Our Board of Directors, under the guidance of the Nominating and Governance Committee, reviews the structure of our Board of Directors and its committees each year as a part of its annual self evaluation process, and in that context considers, among other things, issues of structure and leadership. The Board of Directors is satisfied that its current structure and processes are well suited for the Company, given its simple business model, significant employee stock ownership and size.
     The Board of Directors has delegated risk management and oversight to the Audit Committee. The Audit Committee receives regular reports on risk matters, including financial, legal and regulatory risks, at its quarterly meetings. The Audit Committee oversees the company’s periodic risk assessments and risk-based internal audits. In addition, the Audit Committee meets regularly with the Chief Compliance Officer, principal accounting officer and General Counsel of Greenhill as well as its external and internal auditors, to discuss issues related to risk management. The Audit Committee, in turn, reports any material risk issues which may arise to the full Board of Directors.
Code of Business Conduct and Ethics
     We have adopted a Code of Business Conduct and Ethics applicable to all of our directors and employees, including our principal executive officers, principal financial officer, principal accounting officer, controller and other employees performing similar functions. A copy of this Code of Business Conduct and Ethics is available on our Web site at www.greenhill.com.
     We intend to post on our Web site any amendment to, or waiver from, a provision of our Code of Business Conduct and Ethics that applies to our principal executive officers, principal financial officer, principal accounting officer, controller and other persons performing similar functions within four business days following the date of such amendment or waiver.
Related Person Transactions Policy
     We have adopted a written related person transactions policy, which is administered by the Nominating and Governance Committee. This policy applies to any transaction or series of related transactions or any material amendment to any such transaction involving a related person and the Company or any subsidiary of the Company. For the purposes of the policy, “related persons” consist of executive officers, directors, director nominees, any shareholder beneficially owning more than 5% of the Company’s common stock, and immediate family members of any such persons. Under the policy, the transaction will be referred to the General Counsel, the Chief Executive Officer and/or the Nominating and Governance Committee for review depending on who the “related person” is. Such reviewer will review, approve or ratify the transaction, taking into account all factors that it deems appropriate, including whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction. No reviewer may participate in any review, approval or ratification of any related person transaction in which such reviewer or any of his or her immediate family members is the related person. All determinations by the Chief Executive Officer or the General Counsel under the policy will be reported to the Committee at its next regularly scheduled meeting or earlier if appropriate. The related person transactions discussed in “Certain Relationships and Related Transactions” below were entered into before the adoption of this written policy.

EXECUTIVE COMPENSATION
Compensation Discussion and Analysis
     Overview and Process
     The Compensation Committee of the Board of Directors, which consists entirely of independent outside directors, has overall responsibility for evaluating and approving the executive officer base salary, annual and long-term incentive compensation, benefit, severance, equity-based and other compensation plans, policies and programs of Greenhill. Neither we nor the Compensation Committee has retained any compensation or similar consultants to assist in determining forms or amounts of compensation for employees or directors. Rather, the Compensation Committee maintains a dialogue with the management of Greenhill regarding compensation, industry practices, and the contributions of individual executives which are taken into account in determining compensation. Scott Bok, our Chief Executive Officer, makes recommendations to the Compensation Committee regarding both the form and amount of base salary and incentive compensation each year. The Compensation Committee, in approving annual and long-term incentive compensation, is also aware of the amounts of compensation previously awarded to the executive officers and their level of stock ownership.
     Compensation Philosophy
     Given the critical importance of human capital to our business, we have designed our executive compensation program to attract, motivate and retain the executive leadership necessary for Greenhill to achieve long-term success and increase stockholder value. Our compensation policy has not changed since our initial public offering in 2004. A substantial portion of each executive’s total compensation is variable and delivered on a pay-for-performance basis. We are committed to utilizing the executive compensation program to reinforce our ownership culture and to broaden employee ownership over time. We strongly believe that executive and employee ownership directly aligns the interests of employees and stockholders and promotes long-term stockholder value creation. The key components of the compensation program for executive officers are base salary, annual incentive compensation and long-term incentives, each of which is described below. It has historically been our goal that compensation and benefits in the aggregate represent 50% or less of our annual revenues although we recognize that we may need to exceed this ratio under certain circumstances, as was the case in 2010. In allocating compensation to our executive officers and other senior professionals, our primary emphasis is on evaluating the relative contribution to the company that each executive officer and other senior professional has made and on allocating compensation fairly to reflect those contributions. This allocation changes on an annual basis. See “—Allocation of Compensation” below for a description of 2010 allocations.
     Components of Compensation
     Base Salary Annual base salaries for executive officers were set at $600,000 at the time of our initial public offering in 2004 and have remained at that level since then.
     Executive officer base salaries and subsequent adjustments, if any, will be determined by the Compensation Committee, based on a review of relevant publicly available market data and other factors the Compensation Committee believes are relevant. In addition, the Compensation Committee will consider salary adjustments for the organization’s broader employee population.
     Incentive Compensation Incentive compensation is a key component of Greenhill’s executive compensation strategy. Awards of annual and long-term incentive compensation are generally based on Greenhill’s operating performance and each individual’s contributions to revenue as well as to the development of Greenhill’s client base, strategic development, market position and management. Consistent with our philosophy regarding executive ownership, executive officers are eligible for annual incentive compensation generally payable in the form of cash and long-term incentives payable

16


Table of Contents

in the form of restricted stock units. Annual incentive compensation awards and long-term incentive compensation awards are only granted once a year, generally at the meeting of the Compensation Committee held in January once the revenue and other financial information is available; however, we often make restricted stock unit grants to new employees at the time that they join the firm to foster a sense of ownership. Incentive compensation is awarded pursuant to the terms of Greenhill’s Equity Incentive Plan, which permits the Compensation Committee to select among a variety of types of awards, including cash, stock, options or restricted stock units. While Greenhill has never awarded any stock options and does not expect to do so, if it were to award stock options, such options, under the terms of the Equity Incentive Plan, must be granted with an exercise price of fair market value on the date of the grant, and under the relevant rules of the New York Stock Exchange, the replacement of any such options with lower-priced options would require stockholder approval.
     Annual Incentive Compensation. The aggregate amount of annual incentive compensation will vary from year to year depending on the amount of our revenues, industry practices and other factors. See “— Allocation of Compensation” below for a description of the process for determining the size of 2010 annual incentive compensation awarded.
     Long-Term Incentive Compensation. The aggregate amount of long-term incentive compensation awarded in any year will also vary from year to year depending on the amount of revenues, industry practices and other factors. Greenhill believes the use of significant equity-based awards as part of the compensation program will support the achievement of the firm’s long-term objectives and stockholder value creation, further align executive and stockholder interests and promote executive ownership. Long-term incentive compensation awards of restricted stock units generally will vest pro rata over a period of five years, consistent with our desire to maximize long-term retention of senior professionals. Some awards of restricted stock units may not vest at all for five years, when they vest fully. Restricted stock units are only transferable in limited circumstances. We pay dividend equivalents to the holders of unvested restricted stock units, although such amounts are subject to forfeiture under certain circumstances. See “— Allocation of Compensation” below for a description of the process for determining the size of 2010 long-term incentive compensation awarded.
     Profit Overrides In 2009, we announced our intention to separate our merchant banking business to focus entirely on our financial advisory business, and we sold certain assets of our merchant banking business (including the right to raise successor funds) to certain of our employees engaged in that business. In previous years, in addition to base salary, annual incentive compensation and long-term incentive compensation described above, those executive officers who also served as members of the investment committees of the merchant banking funds or were otherwise actively involved with those funds, and other employees who played significant roles in the investments made by our funds, were eligible to receive as additional compensation in any fiscal year in the form of interests in profit overrides generated by our merchant banking funds (subject to achievement of a minimum investment return for our funds’ outside investors). As of January 1, 2011, none of our employees focuses exclusively on our merchant banking business, as the separation of that business was completed on December 31, 2010. None of the profit override in respect of investments made in 2009 or 2010 was allocated to any of our executive officers. The ultimate value of the profit override allocated to such officers in earlier years in respect of an investment will not be determinable until that investment has been fully divested or otherwise monetized by the fund in question, a process which can take many years. No portion of such profit overrides is paid to employees until such time as the profit overrides are actually paid to Greenhill by the funds. Profit overrides are subject to vesting, generally over a period of four years, and may only be transferred under limited circumstances.

Table of Contents

     Other Forms of Compensation We do not provide any perquisites to any employees other than Mr. Robert F. Greenhill, our Chairman of the Board of Directors and a managing director of Greenhill. Please see “Certain Relationships and Related Transactions” on page 27 for a description of the compensation and perquisites provided to Mr. Greenhill.
     We do not have any pension, severance or deferred compensation plans, except for our tax qualified 401(k) profit sharing plan and pension plans where required by applicable law. We maintain medical, dental, disability and life insurance benefit plans for the benefit of all of our eligible employees.
     Changes in our Executive Officer Team in 2010
     On April 21, 2010, Simon A. Borrows resigned from his position as Co-Chief Executive Officer and Scott L. Bok was appointed as sole Chief Executive Officer. Mr. Borrows stepped down from our Board of Directors on June 30, 2010. Mr. Borrows is now the Chairman of Greenhill & Co. International LLP, our English subsidiary, focusing on some of our most important European clients.
      Allocation of Compensation
     Annual incentive compensation awards and long-term incentive compensation awards are generally granted once at the beginning of each calendar year in respect of performance for the preceding year and a desire for long-term retention of the grant recipients. In order to determine the size of annual incentive and long-term incentive compensation awards to be granted to the executive officers, we begin by determining the available annual incentive compensation pool and long-term incentive compensation pool. Each pool is calculated by multiplying our revenues for the immediately preceding year by a percentage (determined by management in consultation with the Compensation Committee), and subtracting from that number the salaries and benefits paid to all employees, certain other compensation expenses (including the expense attributable to previously issued restricted stock unit grants) and the cash bonuses payable in respect of the preceding fiscal year to all employees other than the managing directors. The remaining amount represents the annual incentive compensation pool out of which cash bonuses to managing directors (including our executive officers) may be awarded.
     The actual percentage of our revenues which was recorded as compensation expense during 2010 was 57%. The actual percentage is determined by management in consultation with the Board of Directors and based on such factors as the relative level of revenues, level of base compensation, the anticipated compensation requirements (which may vary depending on the level of recruitment of new managing directors in any given period and other factors), and the level of other costs and expenses.
     In determining the size of the long-term incentive compensation awards granted to our named executive officers for 2010, the Compensation Committee considered the contributions to revenues, business development and development of the Company of all of the executive officers. In particular, the Compensation Committee noted Mr. Bok’s contributions to the acquisition of Caliburn Partnership Pty Limited (“Caliburn”), an Australian financial advisory firm we acquired in April 2010 (“Caliburn Acquisition”), his role in originating and executing certain client engagements, and Mr. Bok’s contributions to the recruitment of additional managing directors and the expansion of our advisory business. With respect to Mr. Borrows, the Compensation Committee took into account Mr. Borrows’ role in originating and executing certain client engagements. With respect to Mr. Lieb, the Compensation Committee focused on his role in originating and executing certain client engagements, but also Mr. Lieb’s service as one of our principal spokespersons with investors and analysts and his role as Chief Financial Officer. With respect to Mr. Rodriguez and Ms. Ekman, the Compensation Committee noted their contributions to risk management and oversight of the accounting, finance, compliance, legal and other administrative aspects of the management of the Company on a worldwide

18


Table of Contents

basis, as well as their contributions to the Caliburn Acquisition. The actual amount of the awards were determined in part on the basis of the amount of relative revenue contributed, the scope of the client relationships originated and/or maintained, the relative importance of the roles played by the executive officers in the execution of specific transactions, in each case, giving due regard to the complexity and difficulty of the administrative roles played by each such officer and the importance of retaining such officers.
     In 2010, we had higher total financial advisory revenue relative to 2009 and annual incentive compensation awards to employees who contributed to those revenues were increased accordingly. However, our executive officers received no cash bonuses in respect of 2010 in order to pay our other professionals on a competitive basis, to strengthen the retention incentive and because most of our peers increased the stock portion of executive compensation. Moreover, and in order to strengthen the retention incentive for our executive officers, all of long-term incentive compensation received by our executive officers in respect of 2010 was in the form of restricted stock units that do not vest at all for five years, when they vest fully (rather than vesting pro rata over five years).
     Executive Stock Ownership
     Most of our executive officers own significant amounts of stock in Greenhill. See “Security Ownership of Directors, Executive Officers and Certain Beneficial Owners.’’ Scott L. Bok, our Chief Executive Officer, owns Greenhill common stock and restricted stock units with a value which is more than 50 times his base salary (assuming a value of our common stock of $70.97, the closing price of the stock on February 24, 2011). Our Chief Financial Officer, Chief Administrative Officer and General Counsel also own, in the form of stock and restricted stock units, stock of Greenhill well in excess of 3 times their base salaries (assuming a value of our common stock of $70.97, the closing price of our stock on February 24, 2011). As a result, we believe our executive officers have a demonstrable and significant interest in increasing the stockholders’ value over the long term.
     Because we have historically awarded our executive officers and other senior employees long-term incentive compensation in the form of restricted stock units with a vesting period that is generally longer than those used by our peers, and because the stock-based component for the executive officers and other senior employees has historically represented a significant portion of compensation, we have not adopted any stock ownership guidelines.
     Our executive officers are prohibited from hedging or otherwise disposing of the economic risk of ownership of any of our shares owned by them through short sales, option transactions or other derivative instruments.
     Tax and Accounting Implications
     Policy on Qualifying Compensation for Deductibility. Section 162(m) of the Internal Revenue Code limits deductions for non-performance-based annual compensation in excess of $1.0 million paid to certain executive officers. Our policy is to maximize the tax deductibility of compensation payments to our executive officers. We may, however, authorize payments to executive officers that may not be fully deductible if we believe such payments are in our stockholders’ interests as may be the case for portions of the grants of restricted stock units awarded to our executive officers in February 2011.
     Compliance with Section 409A of the Internal Revenue Code. We structure compensation in a manner intended to avoid the incurrence of any additional tax, interest or penalties under Section 409A of the Internal Revenue Code.
     Accounting for Stock-Based Compensation. We account for stock-based compensation in accordance with the requirements of FASB Accounting Standards Codification (“ASC”) Topic 718.

(1)   The units referred to in this column are restricted stock units granted pursuant to our Equity Incentive Plan. No other types of equity awards are outstanding. Those awards marked (A) vested on January 26, 2011; those awards marked (B) vested as to 100% on January 26, 2011; those awards marked (C) vested as to 20% of the original award on January 31, 2011, and the remainder will vest ratably on January 31, 2012; those marked (D) vested as to 20% of the original award on January 28, 2011, and the remainder will vest ratably on January 28 of each of 2012 and 2013; those awards marked (E) vested as to 20% of the original award on January 28, 2011, and the remainder will vest ratably on January 28 of 2012, 2013 and 2014; those marked (F) will vest 100% on January 28, 2014; those marked (G) vested as to 20% of the original award on January 27, 2011, and the remainder will vest ratably on January 27 of each of 2012, 2013, 2014 and 2015; and those marked (H) will vest 100% on January 27, 2015.
 
(2)   The market value has been calculated by multiplying the number of shares underlying the award by the closing price of our common stock on December 31, 2010 (the last trading day of 2010), $81.68. For the purposes of this calculation, we have assumed that all conditions to the vesting of these awards will be fulfilled.

(1)   Value realized upon vesting calculated by multiplying the number of shares acquired upon vesting at the closing market price of the shares on the last trading date prior to each vesting date.
 
(2)   Value realized upon vesting equals the sum of $2,879,168 (in respect of shares vested on March 31, 2010) and $727,784 (in respect of shares vested in January 2010), in each case multiplying the number of shares acquired upon vesting by the closing market price of the shares on the last trading date prior to each vesting date.
Potential Payments upon Termination or a Change of Control
     None of our executive officers or other employees have any severance agreements or arrangements. However, our Equity Incentive Plan provides that upon the death, disability, retirement or upon the termination of employment without cause (as determined by our Compensation Committee) within two years following a change of control or six months prior to a change of control if the Compensation Committee reasonably believes such termination was at the behest of an acquiring entity, any restricted stock unit previously granted will be immediately accelerated and become fully vested (which we refer to as the acceleration provision). The acceleration provision applies to the

25


Table of Contents

restricted stock units held by all of our employees. Had the acceleration provision been triggered on December 31, 2010, the value of the number of shares of our common stock to be delivered on that date to our executive officers would have been as follows (calculated using the closing price of our common stock on December 31, 2010 of $81.68): Mr. Bok, $14,923,998, Mr. Borrows, $11,369,448, Mr. Lieb, $3,421,002, Mr. Rodriguez, $1,791,896 and Ms. Ekman, $1,795,980.
Employment Agreements
     The employment agreements of Messrs. Bok and Rodriguez provide that they will be paid an annual base salary of $600,000, subject to annual review by the Compensation Committee, and that they may be awarded a bonus in an amount to be determined in the sole discretion of the Compensation Committee. These employment agreements are terminable by either party on 90 days’ prior written notice. Mr. Borrows’ employment agreement was terminated in June 2010 and replaced by a substantially similar agreement, except that Mr. Borrows’ salary will be $300,000; that agreement also provides that Mr. Borrows’ remaining restricted stock units will vest fully in three years. All of our executive officers are subject to limitations on their ability to compete with us during the term of their employment and for a three month period thereafter; they are also prohibited from soliciting certain of our employees for a period of six months following the termination of their employment.

As these awards are fully vested, the entire expense arising from them is recognized in the year the services were rendered to which they relate.
     During 2010, directors who were not Greenhill employees received an annual retainer of $100,000 for service on our Board of Directors payable at their option either in cash or stock or a combination. No separate meeting fees were paid. The chairman of the Audit Committee received an additional annual cash retainer of $15,000, which was paid at his option in a combination of cash and stock. We have not retained any compensation consultants to advise on director compensation.
     It is our policy to ask our non-employee directors to retain any stock granted to them as compensation until such time as they complete their service on the Board, subject to exceptions for unforeseen personal circumstances.
     Our non-employee directors also will be reimbursed for reasonable out-of-pocket expenses incurred in connection with their service on the Board and the Board committees. We may also arrange transportation for our directors to and from Board meetings. Employees of Greenhill who also serve as

26


Table of Contents

directors receive compensation for their services as employees, but they do not receive any additional compensation for their service as directors. No other compensation is paid to our Board members in their capacity as directors. Non-employee directors do not participate in our employee benefit plans. See discussion under “Certain Relationships and Related Transactions — Other Compensation” for a description of the compensation paid to Robert F. Greenhill, who is the Chairman of our Board of Directors and an employee of Greenhill, but is not an executive officer.
CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
     We recognize that transactions between us and any of our directors or executives can present potential or actual conflicts of interest or create the appearance that our decisions are based on considerations other than what is in the best interests of the firm and our stockholders. We also recognize that at times, such transactions may actually be in the best interests of the Company. Therefore, to ensure such transactions are given due consideration, our Board of Directors adopted a Related Persons Transaction Policy. Under the policy, the Chief Executive Officer, the General Counsel and the Nominating and Governance Committee are tasked with reviewing the proposed transactions between Greenhill and the related parties and the Nominating and Governance Committee is charged with overseeing the policy. See “Information Regarding the Board of Directors and Corporate Governance — Related Persons Transaction Policy” above.
Related Transactions Involving Our Directors and Executive Officers
Other Compensation
     Mr. Greenhill, one of our directors, is our founder, Chairman and an employee of Greenhill. In 2010, Mr. Greenhill received a total of $8,524,541 in compensation, including $7,316,915 in restricted stock units awarded in 2010 (calculated by multiplying the number of shares underlying the award by the closing price of our common stock on the trading date prior to the grant date of the award). We also provide Mr. Greenhill with a car and driver, with a cost to Greenhill of $158,983 in 2010 (comprised principally of compensation expense in respect of Mr. Greenhill’s driver who is our employee). In addition, Mr. Greenhill uses an aircraft owned by us for personal travel; Mr. Greenhill reimburses us for the costs associated with his personal use of the aircraft. See “—Use of Corporate Aircraft” below. These perquisites are provided only to Mr. Greenhill, in recognition of his role as founder of our firm.
Relationship with Merchant Banking Funds and other Principal Investments
     Greenhill has an indirect interest in three different merchant banking funds and one venture fund, which we refer to as Greenhill Capital Partners I (or Fund I), Greenhill Capital Partners II (or Fund II), Greenhill Capital Partners Europe (or GCP Europe) and Greenhill SAVP (or GSAVP), each of which consists of several related fund vehicles which generally invest in parallel on a pro rata basis (we refer to those funds collectively as the “Funds’’). The managing general partners of the Funds (other than the Original General Partner) are controlled by Greenhill.
     Greenhill’s employees, including all of its executive officers and directors, committed an aggregate of $292 million of capital to the Funds’ total committed capital of $1.8 billion.
     Greenhill and those employees who made capital commitments to the Funds (including all of the executive officers) have entered into a series of agreements with Funds (the “Partnership Agreements’’). The principal terms of such Partnership Agreements are as follows:
     All limited partners in Fund II, GCP Europe and GSAVP who are managing directors or other employees of Greenhill have agreed to pay during the commitment period an annual management fee to the respective managing general partner of such Fund ranging from 1.5% and 2.5% of the capital committed by such limited partners. The commitment period for Fund II terminated on June 7, 2010, and will terminate for GCP Europe on December 31, 2012 and for GSAVP on September 30, 2011, in

27


Table of Contents

each case, unless extended or terminated earlier by the general partner in accordance with the terms of the applicable Partnership Agreements. Upon termination of the relevant commitment period, the annual management fee was reduced to 1% of the invested capital in the case of Fund II, and will be reduced to 2% in the case of GCP Europe, and 1.5% of the invested or reserved capital in the case of GSAVP. Limited partners who are employees of Greenhill (with certain exceptions) also agreed to pay to the managing general partners of the funds certain profit overrides. The Partnership Agreements also provide for the payment by the limited partners of certain expenses incurred by the general partner and for the indemnification of the general partner, its affiliates and their employees under certain circumstances.
     On December 22, 2009, Greenhill closed the previously announced sale of certain of the firm’s merchant banking assets (including the right to raise successor funds) to a newly-formed entity, GCP Capital Holdings, Inc. (“GCP Capital”), owned by Robert H. Niehaus, and V. Frank Pottow, who were, at the time of the sale, employees in our merchant banking business, in exchange for 289,050 shares of Greenhill common stock. Messrs. Niehaus and Pottow remained employees of Greenhill until December 31, 2010, when the separation of the merchant banking business was completed. In connection with the sale, we agreed to commit $5,000,000 to a new merchant banking fund to be raised by GCP Capital, Greenhill Capital Partners III (“GCP III”). A number of our employees have also made commitments to GCP III.
Relationship with Barrow Street Capital
     Barrow Street Capital LLC, or Barrow Street Capital, is a real estate merchant banking firm founded in 1997. One of Barrow Street Capital’s two managing principals is Robert F. Greenhill, Jr., son of Robert F. Greenhill, the Chairman of Greenhill. Barrow Street Capital’s investment committee includes Robert F. Greenhill, Jr., Robert F. Greenhill and other principals of Barrow Street Capital. Greenhill committed $5.0 million to Barrow Street Capital Real Estate Fund III (“BSREF III’’), with its investment bearing no management fees or profit override. The commitment period for BSREF III has ended. Certain of Greenhill’s managing directors also committed capital to BSREF III.
Use of Corporate Aircraft
     Through our wholly-owned subsidiary Greenhill Aviation Co., LLC, we own and operate an airplane that is used by our employees for transportation on business travel and by Robert F. Greenhill and his family for transportation on business and personal travel. We bear all costs of operating the aircraft, including the cost of maintaining air and ground crews. We have an aircraft expense policy in place that sets forth guidelines for personal and business use of the airplane. Mr. Greenhill reimburses the company for the actual out of pocket costs associated with the operation of the company’s aircraft in connection with the personal use thereof by Mr. Greenhill. In 2010, Mr. Greenhill reimbursed us $237,750 for such costs incurred in 2010. No other employees used the aircraft for personal travel in 2010.
     In addition, employees of Greenhill from time to time use airplanes personally owned by Mr. Greenhill for business travel. In those instances, Mr. Greenhill invoices us for the travel expense on terms we believe are comparable to those we could secure from an independent third party. During 2010 we paid $16,652 to an entity controlled by Mr. Greenhill on account of such expenses.
Use of Hangar Space
     Riversville Aircraft Corporation, an entity controlled by Robert F. Greenhill, uses and reimburses us for a portion of the hangar space we lease at the Westchester County Airport. In 2010 Riversville Aircraft Corporation paid us $69,720 in rent and related costs. Riversville Aircraft Corporation reimburses us for its use of a portion of the hangar space on terms we believe are comparable to those we could secure from an independent third party.

Auditor Services Pre-Approval Policy
     The Audit Committee has adopted an auditor services pre-approval policy applicable to services performed for us by our independent auditors. In accordance with this policy, the Committee’s practice is to approve annually all audit services and, on a case-by-case basis, recurring permissible non-audit services to be provided by the independent auditors during the fiscal year. The Audit Committee reviews each non-audit service to be provided and assesses the impact of the service on the auditor’s independence. In addition, the Audit Committee may pre-approve other non-audit services during the year on a case-by-case basis, and delegate authority to grant such pre-approvals during the year to the chairperson of the Audit Committee, so long as the chairperson informs the Audit Committee at its next scheduled meeting.
