	•	a proxy statement of Mariner for use in the solicitation of proxies for Mariner’s annual meeting of stockholders;
	•	a prospectus of Mariner relating to the issuance of shares of Mariner common stock in connection with the merger; and
	•	an information statement of Forest relating to the spin-off of the Forest Gulf of Mexico operations to the shareholders of Forest.

	•	The terms “we”, “us”, “our” and like terms, and the term “Mariner,” refer to Mariner Energy, Inc.;
	•	“MEI Sub” refers to MEI Sub, Inc.;
	•	“Forest” refers to Forest Oil Corporation;
	•	“Forest Energy Resources” refers to Forest Energy Resources, Inc.; and
	•	“Forest Gulf of Mexico operations” refers to the offshore Gulf of Mexico operations conducted by Forest that have been contributed to Forest Energy Resources and the shares of which will be spun-off to Forest shareholders.

Q:		Please briefly describe the proposed merger and related transactions.
A:		Forest has transferred and contributed the assets and certain liabilities associated with its offshore Gulf of Mexico operations to Forest Energy Resources, a newly formed subsidiary of Forest. Immediately prior to the merger, Forest will distribute all of the outstanding shares of Forest Energy Resources to Forest shareholders on a pro rata basis. Forest Energy Resources will then merge with a newly formed subsidiary of Mariner, and become a new wholly owned subsidiary of Mariner. When the merger is complete, approximately 58% of the Mariner common stock will be held by shareholders of Forest and approximately 42% of Mariner common stock will be held by the pre-merger stockholders of Mariner, each on a pro forma basis.

	•	be an independent public company;
	•	own both the Mariner operations and the Forest Gulf of Mexico operations; and
	•	have total assets of approximately $2.1 billion and total debt of approximately $279.0 million on a pro forma combined basis, assuming the spin-off and the merger occurred on September 30, 2005.

Q:		What are Mariner stockholders being asked to vote upon?
A:		Mariner stockholders are being asked to:

	•	adopt the merger agreement entered into among Forest, Forest Energy Resources, Mariner and MEI Sub, Inc., subject to the approval of the proposed amendment to Mariner’s certificate of incorporation;

1

---

Table of Contents

	•	approve the proposed amendment to Mariner’s certificate of incorporation to increase the number of authorized shares of stock from 90 million to 200 million, subject to completion of the merger;
	•	approve the proposed amendment and restatement of Mariner’s stock incentive plan;
	•	to elect one director to serve until the annual meeting of stockholders of Mariner in 2009;
	•	to elect two directors to serve until the annual meeting of stockholders of Mariner in 2007; and
	•	approve the proposed granting of authority to the proxyholders to vote in their discretion on a motion to adjourn or postpone the meeting.

Q:		What changes to Mariner’s stock incentive plan am I being asked to approve?
A:		You are being asked to approve an amendment and restatement of the plan whereby 4.5 million shares of common stock would be added to the plan, the plan would be extended to October 12, 2015 and the number of shares subject to stock options or shares of restricted stock issuable under the plan to any individual would be limited to 2.85 million, subject to the completion of the merger.
Q:		Why am I being asked to grant to the proxy holders the authority to vote in their discretion on a motion to adjourn or postpone the meeting?
A:		We may determine to adjourn or postpone the meeting, for example, to solicit additional proxies if there are insufficient votes at the time of the meeting to adopt the merger agreement.
Q:		What will Forest shareholders receive in the merger?
A:		If the merger is completed, each Forest shareholder will ultimately receive shares of Mariner common stock. As a result of the spin-off, Forest shareholders will initially receive shares of Forest Energy Resources, which will then be converted in the merger into the right to receive shares of Mariner. After the merger, Forest shareholders will be entitled to receive approximately 0.8 shares of Mariner for each Forest share that they own. Forest shareholders will not be required to pay for the shares of Forest Energy Resources distributed in the spin-off transaction or the shares of Mariner issued in the merger. Shareholders will receive cash in lieu of any fractional shares of Mariner common stock. All shares of Forest Energy Resources common stock distributed in the spin-off and Mariner common stock issued in the merger will be issued in book-entry form, meaning that, although Forest shareholders will own the shares, they will not be issued physical share certificates.
Q:		What will Mariner stockholders receive in the merger?
A:		Mariner stockholders will keep the shares of Mariner common stock they currently own, but will not receive any additional shares in the merger.
Q:		Does the Mariner board of directors support the merger and the other proposals?
A:		Yes. The Mariner board of directors has determined that the merger is fair to and in the best interests of Mariner and its stockholders, and that the merger agreement is advisable. The Mariner board of directors has unanimously approved the merger agreement and the other proposals and recommends that the Mariner stockholders vote “for” the adoption of the merger agreement and the other proposals. A more detailed description of the background and reasons for the merger is set forth under “The Spin-Off and Merger” beginning on page 41.
Q:		Do the directors and executive officers of Mariner have interests in the merger that are different from mine?
A:		When considering the recommendations of the Mariner board of directors, you should be aware that the directors and executive officers of Mariner have interests and arrangements that may be different from your interests as stockholders, including:

	•	arrangements regarding the appointment of directors and officers of Mariner following the merger; and
	•	arrangements whereby the executive officers of Mariner will receive a cash payment of $1,000 each in exchange for the waiver of certain rights under their employment agreements, including the automatic

		vesting or acceleration of restricted stock and options upon the completion of the merger and the right to receive a lump sum cash payment if the officer voluntarily terminates employment without good reason within nine months following the completion of the merger.

Q:		What factors did the Mariner board of directors consider in reaching its decision on the merger?
A:		In reaching its decision on the merger, the Mariner board of directors considered a number of factors, including the following among others:

	•	the increased size of the combined company could reduce volatility and allow it to participate in larger scale drilling projects and acquisition opportunities;
	•	the merger would be expected to increase Mariner’s estimated proved reserves and undeveloped acreage;
	•	the merger could generate increased visibility in the capital markets and trading liquidity for the combined company;
	•	the merger would increase the number of Mariner’s producing fields, thereby reducing Mariner’s dependence on a concentrated number of properties;
	•	the merger would be consummated only if approved by the holders of a majority of the Mariner common stock; and
	•	the merger is structured as a tax-free reorganization for U.S. federal income tax purposes and, accordingly, would not be taxable either to Mariner or its stockholders.

		The Mariner board of directors also identified and considered some risks and potential disadvantages associated with the merger, including, among others, the following:

	•	the risk that there may be difficulties in combining the business of Mariner and the Forest Gulf of Mexico operations;
	•	the risk that the potential benefits sought in the merger might not be fully realized;
	•	the risk that the proved undeveloped, probable and possible reserves of the Forest Gulf of Mexico operations may never be converted to proved developed reserves; and
	•	the fact that, in order to preserve the tax-free treatment of the spin-off, Mariner would be required to abide by restrictions that could reduce its ability to engage in certain business transactions.

		In the judgment of the Mariner board of directors, the potential benefits of the merger outweigh the risks and the potential disadvantages.
Q:		Did Mariner’s financial advisor render its opinion with respect to the fairness from a financial point of view of the exchange ratio in the merger?
A:		Yes. Lehman Brothers Inc., Mariner’s financial advisor, has delivered to Mariner’s board of directors a written opinion that, as of September 9, 2005, based upon and subject to the factors and assumptions set forth in the opinion, the exchange ratio in the merger was fair from a financial point of view to Mariner. This opinion is attached as Annex B to this proxy statement/prospectus-information statement.
Q:		Are there risks that Mariner stockholders should consider in deciding whether to vote on the merger?
A:		Yes. Mariner stockholders should read the “Risk Factors” beginning on page 24 for a description of various risks Mariner stockholders should carefully consider in evaluating the proposed merger.

Q:		Can Mariner stockholders dissent and require appraisal of their shares of Mariner common stock?
A:		No. Mariner stockholders are not entitled to dissenters’ rights or appraisal rights in connection with the merger.
Q:		Why does Mariner want to increase the number of authorized Mariner shares?
A:		Mariner’s certificate of incorporation currently does not authorize a sufficient number of shares of common stock to complete the merger. Mariner currently is authorized to issue 70 million shares of Mariner common stock and 20 million shares of Mariner preferred stock. As of February 1, 2006, approximately 35.6 million shares of Mariner common stock were issued and outstanding. Under the terms of the merger agreement, Mariner must issue approximately 50.6 million shares (representing approximately 0.8 shares of Mariner common stock for each share of Forest common stock) of common stock in the merger, which would result in approximately 86  million shares of Mariner common stock outstanding. Therefore, the number of authorized shares of Mariner common stock must be increased in order to complete the merger.
Q:		What vote is required to adopt the merger agreement and the other proposals?
A:		For the merger to occur, the holders of a majority of the outstanding Mariner common stock must adopt the merger agreement and approve the amendment to the certificate of incorporation. The amendment to Mariner’s stock incentive plan must be approved by a majority of votes cast by stockholders present in person or by proxy, a quorum being present. Director nominees receiving a plurality of all votes cast at the meeting will be elected to Mariner’s board of directors. Mariner stockholders will have one vote for each share of Mariner common stock they own. On February 1, 2006, the record date for Mariner’s annual meeting, 35,615,400 shares of Mariner common stock were issued and outstanding and entitled to vote at the meeting. The approval of Forest shareholders is not required for the spin-off or the merger.
Q:		Where will Mariner’s common stock be listed?
A:		Mariner’s common stock has been approved for listing on the New York Stock Exchange upon the completion of the merger.
Q:		Who will be the executive officers of Mariner?
A:		The current executive officers of Mariner will remain in their current positions following the merger.
Q:		Who will be the directors of Mariner?
A:		If the merger is completed, Mariner’s board will consist of seven members, five of whom will be the current directors of Mariner, and two of whom will be mutually agreed between Mariner and Forest prior to the completion of the merger. The Chairman of the Mariner board will be Mr. Scott D. Josey, the current Chairman, Chief Executive Officer and President of Mariner.
Q:		Who are the new directors of Mariner, as mutually agreed by Forest and Mariner?
A:		The two Mariner directors to be mutually agreed by Forest and Mariner pursuant to the terms of the merger agreement have not yet been designated.
Q:		When do you expect to complete the spin-off and the merger?
A:		If the merger agreement and the proposed amendment to the certificate of incorporation are adopted and approved by the stockholders of Mariner, then Mariner, Forest, Forest Energy Resources and MEI Sub expect to complete the spin-off and the merger as soon as possible after the satisfaction (or waiver, where permissible) of the other conditions to the spin-off and the merger. We currently anticipate that the merger will be completed during the first calendar quarter of 2006.
Q:		Who is entitled to vote at the meeting of Mariner stockholders?
A:		Holders of Mariner common stock of record at the close of business on February 1, 2006.

Q:		What should Mariner stockholders do now?
A:		You should mail your signed and dated proxy card(s) in the enclosed envelope or vote via telephone or via the Internet by following the instructions on your proxy card(s) as soon as possible so that your shares of Mariner common stock will be represented and voted at the meeting.
Q:		Do Mariner stockholders need to send in their share certificate(s)?
A:		No. Mariner stockholders should not send in their share certificate(s). Mariner stockholders will not exchange their share certificates in connection with the merger.
Q:		If I am not going to attend the meeting, should I return my proxy card(s)?
A:		Yes. Returning your proxy card(s) ensures that your shares of Mariner common stock will be represented at the meeting, even if you are unable to or do not attend.
Q:		How do I vote my shares of Mariner common stock if they are held in the name of a bank, broker or other fiduciary?
A:		Your bank, broker or other fiduciary will vote your shares of Mariner common stock with respect to the merger only if you provide written instructions to them on how to vote, so it is important that you provide them with instructions. If you do not provide them with instructions, they will not be authorized to vote with respect to the merger or the other proposals. If you wish to vote in person at the meeting and hold your shares of Mariner common stock in the name of a bank, broker or other fiduciary, you must contact your bank, broker or other fiduciary and request a legal proxy. You must bring this legal proxy to the meeting in order to vote in person. Shares of Mariner common stock held by a broker, bank or other fiduciary that are not voted because the customer has not provided instructions to the broker, bank or other fiduciary (referred to as a “broker non-vote”) will have the same effect as a vote “against” the proposals.
Q:		Can I change my vote after I mail my proxy card(s)?
A:		Yes. If you are a record holder of Mariner common stock, you can change your vote by:

		• completing, signing and dating a new proxy card and returning it by mail so that it is received prior to the meeting;
		• voting via telephone or via the Internet by following the instructions provided on your proxy card;
		• sending a written notice to The Continental Stock Transfer & Trust Company that is received prior to the meeting stating that you revoke your proxy; or
		• attending the meeting and voting in person or by legal proxy, if appropriate.
		Internet and telephone voters may use the same procedure to revoke or change their votes as they used to cast their original votes. If your shares of Mariner common stock are held in the name of a bank, broker or other fiduciary and you have directed such person(s) to vote your shares of Mariner common stock, you should instruct such person(s) to change your vote or obtain a legal proxy to do so yourself. Telephone and Internet voting will close at 8:00 p.m. Eastern time on the day before the meeting. Thereafter, voting (including revocation of proxies) can be made by mail or facsimile received prior to the meeting, or in person at the meeting.

Q:		What if I do not vote, or abstain from voting, or do not instruct my broker to vote my shares of Mariner common stock?
A:		If you do not vote, it will have the same effect as a vote against the merger and the proposal to amend Mariner’s certificate of incorporation. Shares that are not voted will not count for purposes of calculating a quorum, which is necessary to have a valid meeting of stockholders. If a quorum of stockholders is not present in person or by proxy at the meeting, no vote will be taken on the merger and the other proposals. Shares that are not voted have the effect of reducing the number of shares required to approve the proposal to amend and restate Mariner’s stock incentive plan and to elect directors, which require the affirmative vote of a majority of a quorum, but do not have the effect of reducing the number of shares required to adopt the merger agreement and to approve the proposed amendment to Mariner’s certificate of

		incorporation, both of which require the affirmative vote of a majority of Mariner’s outstanding shares. Abstentions and broker non-votes also will have the effect of votes against the merger and the proposal to amend Mariner’s certificate of incorporation. If you sign your proxy card but do not indicate how you want to vote, your shares of Mariner common stock will be voted for the merger and the other proposals.
Q:		What factors did the Forest board of directors consider in reaching its decision on the spin-off and merger?
A:		In reaching its decision on the spin-off and the merger, the Forest board of directors considered a number of factors, including the following among others:

		• the transaction creates two highly focused and valuable enterprises for Forest’s shareholders, Forest and Mariner;
		• the merger of the Forest Gulf of Mexico operations with the Mariner business creates a high quality, well positioned Gulf of Mexico independent with an excellent track record and growth outlook;
		• following the spin-off, Forest will be a highly-focused onshore resource company with an acquire and exploit strategy and a portfolio of long-life, concentrated assets in high quality basins that provide a foundation for sustainable growth;
		• the determination to execute a tax-free transaction designed to increase the value of Forest’s Gulf of Mexico assets; and
		• the determination that a spin-off followed by a merger transaction represents a better alternative for Forest’s shareholders than any other type of transaction considered, providing optionality and returning value directly to Forest’s shareholders.
		The Forest board of directors also considered some risks and potential disadvantages associated with the spin-off and merger, including the following among others:
		• the lack of a liquid trading market and established market value for the Mariner shares;
		• the risk that there may be difficulties in combining the business of Mariner and the Forest Gulf of Mexico operations;
		• the risk that the potential benefits sought in the merger might not be fully realized; and
		• the risk that the proved undeveloped, probable and possible reserves of the Mariner business may never be converted to proved developed reserves.
		In the judgment of the Forest board of directors, the potential benefits of the spin-off and the merger outweigh the risks and the potential disadvantages. In evaluating Mariner’s offer, Forest believed that the combination of stock and assumed liabilities offered by Mariner could be worth an amount in a range of approximately $1.1 billion to $1.4 billion, depending upon the trading value of Mariner’s common stock when the stock begins to trade upon the closing of the merger.

Q:		Do Forest shareholders need to send in any share certificates?
A:		No. If the merger is completed, Forest shareholders will exchange their shares of Forest Energy Resources for share certificates representing Mariner common stock. Forest shareholders who are entitled to receive shares of Forest Energy Resources (i.e., shareholders of record on the record date for the distribution) will be mailed book entry statements evidencing their shares of Forest Energy Resources. The exchange of Forest Energy Resources and Mariner shares will be effected through book-entry, without the exchange of physical share certificates.
Q:		Has Forest set a record date for the distribution of Forest Energy Resources shares in the spin-off?
A:		No. Forest will publicly announce the record date when it has been determined.

Q:		Can Forest shareholders dissent and require appraisal of their shares of Forest Energy Resources common stock?
A:		No. Forest shareholders are not entitled to dissenters’ rights or appraisal rights in respect of the Forest Energy Resources stock they receive in the merger.
Q:		What should Forest shareholders do now?
A:		Forest shareholders should carefully read this proxy statement/prospectus-information statement, which contains important information about the spin-off, the merger, Mariner, the Forest Gulf of Mexico operations and the combined businesses. Forest shareholders are not required to take any action to approve the spin-off or the merger. As described above, if the merger is completed, shares of Forest Energy Resources will be converted into shares of Mariner common stock.

	The integration of the Forest Gulf of Mexico operations following the merger will be difficult, and will divert our management’s attention away from our normal operations.

	•	the challenge of integrating the Forest Gulf of Mexico operations while carrying on the ongoing operations of our business;
	•	the challenge of managing a significantly larger company, with more than twice the PV10 of Mariner on a stand-alone basis;
	•	faulty assumptions underlying our expectations;
	•	the difficulty associated with coordinating geographically separate organizations;
	•	the challenge of integrating the business cultures of the two companies;
	•	attracting and retaining personnel associated with the Forest Gulf of Mexico operations following the merger; and
	•	the challenge and cost of integrating the information technology systems of the two companies.

	If we fail to realize the anticipated benefits of the merger, stockholders may receive lower returns than they expect.

	We expect to incur significant charges relating to the integration plan that could materially and adversely affect our period-to-period results of operations following the merger.

	The number of shares Forest shareholders will receive in the merger is not subject to adjustment based on the value of the Mariner or the Forest Gulf of Mexico operations. Accordingly, because this value may fluctuate, the market value of the Mariner common stock that Forest shareholders receive in the merger may not reflect the value of the individual companies at the time of the merger.

	Regulatory agencies may delay or impose conditions on approval of the spin-off and the merger, which may diminish the anticipated benefits of the merger.

	In order to preserve the tax-free treatment of the spin-off, we will be required to abide by potentially significant restrictions which could limit our ability to undertake certain corporate actions (such as the issuance of our common shares or the undertaking of a change in control) that otherwise could be advantageous.

	Some of our directors and executive officers have interests that are different from, or in addition to, the interests of our stockholders.

	•	arrangements regarding the appointment of directors and officers of Mariner following the merger; and
	•	arrangements whereby our executive officers will receive a cash payment of $1,000 each in exchange for the waiver of certain rights under their employment agreements, including the automatic vesting or acceleration of restricted stock and options upon the completion of the merger and the right to receive a lump sum cash payment if the officer voluntarily terminates employment without good reason within nine months following the completion of the merger.

	Oil and natural gas prices are volatile, and a decline in oil and natural gas prices would reduce our revenues, profitability and cash flow and impede our growth.

	Reserve estimates depend on many assumptions that may turn out to be inaccurate. Any material inaccuracies in these reserve estimates or underlying assumptions will affect materially the quantities and present value of our reserves and the reserves of the Forest Gulf of Mexico operations, which may lower our bank borrowing base and reduce our access to capital.

Table of Contents

	In estimating future net revenues from proved reserves, we and Forest assume that future prices and costs are fixed and apply a fixed discount factor. If these assumptions or discount factor are materially inaccurate, our revenues, profitability and cash flow could be materially less than our estimates.

	Unless we replace our oil and natural gas reserves, our reserves and production will decline.

	Relatively short production periods or reserve life for Gulf of Mexico properties subjects us to higher reserve replacement needs and may impair our ability to replace production during periods of low oil and natural gas prices.

	Any production problems related to our Gulf of Mexico properties could reduce our revenue, profitability and cash flow materially.

	Our exploration and development activities may not be commercially successful.

	•	unexpected drilling conditions;
	•	pressure or irregularities in formations;
	•	equipment failures or accidents;
	•	adverse weather conditions, including hurricanes, which are common in the Gulf of Mexico during certain times of the year;
	•	compliance with governmental regulations;
	•	unavailability or high cost of drilling rigs, equipment or labor;
	•	reductions in oil and natural gas prices; and
	•	limitations in the market for oil and natural gas.

	Our exploratory drilling projects are based in part on seismic data, which is costly and cannot ensure the commercial success of the project.

	Oil and gas drilling and production involve many business and operating risks, any one of which could reduce our levels of production, cause substantial losses or prevent us from realizing profits.

	We will require additional capital to fund our future activities. If we fail to obtain additional capital, we may not be able to implement fully our business plan, which could lead to a decline in reserves.

	Properties we acquire (including the Forest Gulf of Mexico properties) may not produce as projected, and we may be unable to determine reserve potential, identify liabilities associated with the properties or obtain protection from sellers against such liabilities.

	Market conditions or transportation impediments may hinder our access to oil and natural gas markets or delay our production.

	The unavailability or high cost of drilling rigs, equipment, supplies or personnel could affect adversely our ability to execute on a timely basis our exploration and development plans within budget, which could have a material adverse effect on our financial condition and results of operations.

	Competition in the oil and natural gas industry is intense, and many of our competitors have resources that are greater than ours giving them an advantage in evaluating and obtaining properties and prospects.

	Financial difficulties encountered by our farm-out partners or third-party operators could affect the exploration and development of our prospects adversely.

	We cannot control the drilling and development activities on properties we do not operate, and therefore we may not be in a position to control the timing of development efforts, the associated costs or the rate of production of the reserves.

	Governance Structure. Under the terms of the merger agreement, the board of directors of Mariner after completion of the merger will be comprised of seven individuals, five of whom are current directors of Mariner, and two of whom will be mutually agreed to by Mariner and Forest prior to the completion of the merger.
	Payments for Waivers of Rights under Employment Agreements. The executive officers of Mariner will receive cash payments of $1,000 each in exchange for the waiver of certain rights under their employment agreements, including the automatic vesting or acceleration of restricted stock and options upon the completion of the merger and the right to receive a lump sum cash payment, equal to 2.0 (2.5 for Mr. Polasek and 2.99 for Mr. Josey) times the sum of the officer’s base salary and three year average annual bonus, if the officer voluntarily terminates employment without good reason within nine months following the completion of the merger.
	Severance Arrangements. The executive officers have employment agreements that will remain in effect after the completion of the merger. These agreements generally entitle the officers to severance benefits in the event of a resignation for good reason, a termination without cause or, in the case of Scott Josey’s agreement, Mariner’s non-renewal of the agreement. These severance benefits are comprised of (i) a payment equal to 18 months of salary continuation (two years for Mr. Josey and Mr. Polasek) at the highest rate in effect prior to termination, (ii) health care coverage for a period of eighteen months (two years for Mr. Josey and Mr. Polasek), (iii) an amount equal to the sum of all bonuses paid to the officer in the year prior to the year in which termination occurs, (iv) 100% vesting of all restricted shares under our Equity Participation Plan, and (v) 50% vesting of all other rights under any other equity plans, including our Stock Incentive Plan.
	The employment agreements also provide for certain change of control benefits. Upon termination for any reason other than cause at any time within nine months after a change of control that occurs while the executive is employed, or upon the occurrence of a change of control within nine months following resignation of employment for good reason or termination without cause, the agreements provide for the following benefits: (i) a lump sum payment equal to 2.0 (2.5 for Mr. Polasek and 2.99 for Mr. Josey) times the sum of the officer’s base salary and three year average annual bonus, and (ii) 100% vesting of all rights under any equity plans, including our Equity Participation Plan and our Stock Incentive Plan. The officers are entitled to a full tax gross-up payment if the aggregate payments and benefits to be provided constitute a “parachute payment” subject to a Federal excise tax. Pursuant to the waivers described above, the executive officers will waive their rights to the automatic vesting or acceleration of restricted stock and options upon completion of the merger and to receive a lump sum payment if they terminate their employment with Mariner without good reason within nine months following the completion of the merger.

	•	the increased size of the combined company, which would have approximately three times the pro forma daily net production of Mariner on a stand-alone basis, could reduce volatility related to large-scale deepwater projects, and could allow it to participate in larger scale exploratory and development drilling projects and acquisition opportunities than would be available to Mariner on a stand-alone basis;
	•	the merger would be expected to increase Mariner’s estimated proved reserves, on a pro forma basis as of December 31, 2004, by approximately 243%, making Mariner larger on a reserve basis than many of its peer companies, and would more than double Mariner’s undeveloped acreage;
	•	the integration of the businesses and the realization of expected benefits could be facilitated by the fact that Mariner is already active in the Gulf of Mexico with assets that are complementary to the Forest Gulf of Mexico assets;
	•	the merger could generate increased visibility in the capital markets and trading liquidity for the combined company, which could enhance the market valuation of Mariner common stock;

Table of Contents

	•	the merger would increase the number of Mariner’s producing fields by approximately 400%, thereby diversifying Mariner’s asset base and reducing Mariner’s dependence on a concentrated number of properties;
	•	the assets comprising the Forest Gulf of Mexico operations, which historically have been used as a cash flow generator for Forest, could be candidates for increased exploitation;
	•	oil and natural gas prices are currently at or near historical highs, which could increase the revenues and enhance the profitability of the Forest Gulf of Mexico operations;
	•	the merger would be consummated only if approved by the holders of a majority of the Mariner common stock;
	•	the merger is structured as a tax-free reorganization for U.S. federal income tax purposes and, accordingly, would not be taxable either to Mariner or its stockholders;
	•	the board’s belief that the potential financial benefits stemming from the enhanced growth prospects of the combined company outweigh the anticipated direct and indirect costs of the merger;
	•	the terms of the merger agreement permit Mariner to terminate the merger agreement at any time before the meeting to accept a superior proposal, subject to its obligation to comply with certain procedural requirements and to pay a termination fee and expense reimbursement; and
	•	the opinion, dated September 9, 2005, of Lehman Brothers Inc. to the Mariner board of directors that, as of that date, based upon and subject to the factors and assumptions set forth in the opinion, the exchange ratio in the merger was fair from a financial point of view to Mariner.

	•	the risk that there may be difficulties in combining the business of Mariner and the Forest Gulf of Mexico operations;
	•	the risk that the potential benefits sought in the merger might not be fully realized;
	•	the risk that the proved undeveloped, probable and possible reserves of the Forest Gulf of Mexico operations may never be converted to proved developed reserves;
	•	the risks inherent in owning properties located in the Gulf of Mexico, including the risks of future hurricanes that could damage or destroy the acquired properties;
	•	the risk that current high commodity prices could fall, thereby reducing the profitability of the acquired operations;
	•	the risk that the merger might not be completed;
	•	the fact that, in order to preserve the tax-free treatment of the spin-off, Mariner would be required to abide by restrictions that could reduce its ability to engage in certain business transactions that otherwise might be advantageous;
	•	the fact that under the merger agreement, Mariner could be required to pay Forest a termination fee and expense reimbursement in certain circumstances; and

	Material U.S. Tax Consequences of the Spin-Off

	•	a Forest shareholder will not recognize any income, gain or loss as a result of the spin-off;
	•	a Forest shareholder’s aggregate tax basis for his or her Forest common stock on which Forest Energy Resources common stock is distributed and the Forest Energy Resources common stock received by such shareholder in the spin-off will be the same as the tax basis of Forest common stock held by such shareholder immediately prior to the spin-off. A Forest shareholder’s aggregate tax basis will be allocated between his or her Forest common stock and Forest Energy Resources common stock received in the spin-off in proportion to the relative fair market value of the Forest common stock and Forest Energy Resources common stock on the spin-off date;
	•	a Forest shareholder’s holding period for the Forest Energy Resources common stock received in the spin-off will include the holding period of the Forest common stock on which the distribution is made; and
	•	Forest will not recognize any income, gain or loss on the spin-off, other than with respect to any “excess loss account” or “intercompany transaction” required to be taken into account by Forest under the Treasury regulations relating to consolidated returns. It is also possible that Forest may recognize income with respect to certain cash received from Forest Energy Resources under the distribution agreement.

	Material U.S. Tax Consequences of the Merger

	•	Mariner receive an opinion from Baker Botts L.L.P., dated as of the effective date of the merger, to the effect that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code; and
	•	Forest and Forest Energy Resources receive an opinion from Weil, Gotshal & Manges LLP, tax counsel to Forest, dated as of the effective date of the merger, to the effect that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code.

	•	a Mariner stockholder will not recognize gain or loss pursuant to the merger, and such holder’s tax basis and holding period in Mariner common stock will not be affected by the merger;

	•	a Forest Energy Resources stockholder who exchanges Forest Energy Resources common stock solely for Mariner common stock in the merger will not recognize gain or loss except, as described below, to the extent of any cash received in lieu of fractional shares of Mariner common stock;
	•	the aggregate tax basis in the Mariner common stock a Forest Energy Resources stockholder receives in the merger (including any fractional shares for which cash is received) will be the same as his or her aggregate tax basis in the Forest Energy Resources common stock surrendered in the merger;
	•	the holding period of the Mariner common stock received in the merger by a holder of Forest Energy Resources common stock (including any fractional shares for which cash is received) will include the holding period of Forest Energy Resources common stock that such stockholder surrendered in the merger; and
	•	a Forest Energy Resources stockholder who receives fractional share proceeds as a result of the sale of shares of Mariner common stock by the transfer agent will be treated as if such fractional share had been received by the shareholder as part of the merger and then sold by such stockholder. Accordingly, such stockholder will recognize capital gain or loss equal to the difference between the cash so received and the portion of the tax basis in Mariner common stock that is allocable to such fractional share. Any such capital gain or loss will be treated as a long-term or short-term capital gain or loss based on the holder’s holding period for the Mariner common stock (as determined above). Non-U.S. holders who receive fractional share proceeds may be subject to withholding tax with respect to the fractional share proceeds under special rules governing the disposition of interests in a United States real property holding corporation.

	•	our high-quality assets with geographic and geological diversity;
	•	our successful track record of finding and developing oil and gas reserves; and
	•	our depth of operating experience.

	•	Our deepwater projects have the potential to provide large reserves, high production volumes and substantial cash flow. Approximately 65 Bcfe of our undeveloped estimated proved reserves as of December 31, 2004, are located in our high-impact deepwater projects — Swordfish, Pluto, Rigel, Baccarat, and Daniel Boone. The Baccarat project commenced production in July 2005 (although production was shut-in due to Hurricane Rita and recommenced in January 2006), and the Swordfish project commenced production in October 2005. Notwithstanding delays caused primarily by 2005 hurricane activity, we believe Pluto and Rigel will commence production in the second quarter of 2006. Proved undeveloped reserves attributable to those projects have been recategorized as proved developed reserves. Daniel Boone is currently scheduled for production in 2008.
	•	The Gulf of Mexico is an area that offers substantial growth opportunities, and we expect to continue to generate shelf, deep shelf and deepwater Gulf of Mexico prospects. The Forest Gulf of Mexico assets will more than double our existing undeveloped acreage position to approximately 465,000 net acres and increase our total net leasehold acreage offshore to nearly 1 million acres, providing numerous exploration, exploitation and development opportunities. We believe the additional acreage also will provide increased exposure to farm-out opportunities from other oil and gas operators. Our team of geoscientists currently has access to seismic data from multiple, recent vintage 3-D seismic databases covering more than 6,600 blocks in the Gulf of Mexico that we intend to continue to use to develop prospects on acreage being evaluated for leasing and to develop and further refine prospects on our expanded acreage position. The combination of our undeveloped acreage position, inventory of development prospects, seismic data and technical knowledge should enhance our ability to select

		projects with the greatest return potential for future development. We will also gain access to a significant infrastructure in the shelf that we believe will provide substantial cost efficiencies to the combined operations.
	•	Our West Texas assets provide stable cash flow and long-lived reserves, with significant development opportunities. In West Texas, during the three years ended December 31, 2004, we drilled 105 wells, all commercially successful, added approximately 76 Bcfe of estimated proved reserves, and increased our average daily production by more than 400%. Our 52 Bcfe of undeveloped estimated proved reserves in West Texas includes 162 locations. Our recent West Texas acquisition adds to our asset base an approximate 35% working interest in over 200 existing producing wells and, we believe, will provide future infill development opportunities, much like our Aldwell unit. This recent acquisition, in conjunction with our existing West Texas acreage, gives Mariner an inventory of multi-year development drilling opportunities.

(1)	Transaction costs consisting of accounting, consulting and legal fees are anticipated to be approximately $12 million. These costs are directly attributable to the transaction and have been excluded from the pro forma financial statements as they represent material nonrecurring charges.
(2)	To record other current and long-term assets that we will receive in the spin-off and liabilities that we will assume as a result of the spin-off reflected at their estimated fair market values, including inventory of $2.1 million, abandonment escrows of $0.7 million, gas imbalances of $7.6 million, asset retirement obligations of $146.6 million and derivative liabilities of $125.2 million.
(3)	To record the preliminary purchase price allocation to the fair value of assets acquired, including oil and gas properties and goodwill. These adjustments also adjust depreciation, depletion and amortization expense to give effect to the acquisition of the Forest Gulf of Mexico operations and their step-up in value using the unit of production method under the full cost method of accounting.
(4)	To record the deferred tax position of the combined company, inclusive of the deferred tax gross-up in connection with the acquisition.
(5)	To record $200.0 million of debt that Forest Energy Resources, Inc. will incur under the terms of the distribution agreement. The actual amount of debt to be incurred will be adjusted to reflect the net cash proceeds generated by the Forest Gulf of Mexico operations since June 30, 2005 pursuant to the terms of the distribution agreement. Mariner plans to refinance the debt, which will mature 90 days after the closing, with a revolving credit facility that matures on the fourth anniversary of the closing. Forest Energy Resources, Inc. will be primarily liable for all indebtedness incurred in connection with the spin-off or any refinancing thereof.
(6)	To record issuance of 50,637,010 shares of common stock at par value of $.0001 per share.
(7)	The Forest Gulf of Mexico operations historically have been operated as part of Forest’s total oil and gas operations. No historical GAAP-basis financial statements exist for the Forest Gulf of Mexico operations on a stand-alone basis; however, statements of revenues and direct operating expenses are presented for the year ended December 31, 2004 (audited) and for the nine months ended September 30, 2005 (unaudited).
(8)	To adjust depreciation, depletion and amortization expense to give effect to the acquisition of the Forest Gulf of Mexico operations and their step-up in value using the unit of production method under the full cost method of accounting.
(9)	To adjust interest expense to give effect to the financing activities in connection with the organization of Forest Energy Resources, Inc. assuming an interest rate of 5.34% for the nine months ended September 30, 2005 and 3.92% for the year ended December 31, 2004 based on the terms of the senior term loan facility to be obtained by Forest Energy Resources. The interest rates used reflect 30-day LIBOR plus 1.50%, or 5.34% as of September 30, 2005 and 3.92% as of December 31, 2004. A change in interest rates of 1/8 percent would result in a change in interest expense of approximately $0.1 million and $0.2 million for the nine months ended September 30, 2005, and the year ended December 31, 2004, respectively.

(10)	To record income tax expense on the combined company results of operations based on a statutory combined federal and state tax rate of 35%.

EBITDA means earnings before interest, income taxes, depreciation, depletion and amortization. For the nine months ended September 30, 2005, EBITDA includes $17.6 million in non-cash stock compensation expense related to restricted stock and stock options granted in 2005. We believe that EBITDA is a widely accepted financial indicator that provides additional information about our ability to meet our future requirements for debt service, capital expenditures and working capital, but EBITDA should not be considered in isolation or as a substitute for net income, operating income, net cash provided by

	operating activities or any other measure of financial performance presented in accordance with generally accepted accounting principles or as a measure of a company’s profitability or liquidity.
(2)	In accordance with SFAS No. 133 “Accounting for Derivative Instruments and Hedging Activities,” as amended by SFAS No. 137 and No. 138, we de-designated our contracts effective December 2, 2001 after the counterparty (an affiliate of Enron Corp.) filed for bankruptcy and recognized all market value changes subsequent to such de-designation in our earnings. The value recorded up to the time of de-designation and included in Accumulated Other Comprehensive Income (“AOCI”), has reversed out of AOCI and into earnings as the original corresponding production, as hedged by the contracts, is produced. We have designated subsequent hedge contracts as cash flow hedges with gains and losses resulting from the transactions recorded at market value in AOCI, as appropriate, until recognized as operating income in our Statement of Operations as the physical production hedged by the contracts is delivered.

(2)	This field was shut-in in April 2004 pending the drilling of a new well and installation of an extension to the existing infield flowline and umbilical. As a result, as of December 31, 2004, 9.0 Bcfe of our net proved reserves attributable to this project were classified as proved undeveloped reserves. We expect production from Pluto to recommence in the second quarter of 2006.

(1)	As of December 31, 2004, we had incurred debt obligations under our credit facility and the JEDI promissory note that are due as follows: $10 million in 2006; and $105 million in 2007. However, we used a portion of the net proceeds of the private equity placement to repay a portion of amounts outstanding under our credit facility and $6 million under the JEDI promissory note. As of November 30, 2005, we had incurred debt obligations under our credit facility of $75 million and under the JEDI promissory note of $4 million.
(2)	Interest obligations represent approximately 14 months of interest due on the JEDI promissory note at 10%. Future interest obligations under our credit facility are uncertain, due to the variable interest rate on fluctuating balances. Based on a 5.2% weighted average interest rate on amounts outstanding under our credit facility as of December 31, 2004, $5.5 million, $5.5 million and $0.9 million would be due under the credit facility in 2005, 2006 and 2007, respectively.
(3)	As of September 30, 2005, the fair value of the derivative liabilities was $105.1 million, including $76.9 million due in less than one year.

(4)	Mariner served as operator until December 2005, at which time pursuant to certain contractual arrangements, Noble Energy, Inc., a 60% partner in the project, began serving as operator.
(5)	This field was shut-in in April 2004 pending the drilling of a new well and installation of an extension to the existing infield flowline and umbilical. As a result, as of December 31, 2004, 9.0 Bcfe of our net proved reserves attributable to this project were classified as proved undeveloped reserves. We expect production from Pluto to recommence in the second quarter of 2006.
(6)	Field has been shut in since September 2004 due to destruction of host platform by Hurricane Ivan.

(1)	As of January 31, 2006, bonuses for 2005 have not yet been paid.
(2)	Dollar amounts are calculated by multiplying the number of shares of common stock awarded by $14, the trading price of our common stock on the business day immediately preceding the date the award was granted. Grantees are entitled to vote, and accrue dividends on, the restricted stock prior to vesting; provided, that any dividends that accrue on the restricted stock prior to vesting will only be paid to grantees to the extent the restricted stock vests. Except in specified circumstances, the restricted shares will be automatically forfeited in the event a grantee’s employment terminates prior to the vesting date of the awards. The restricted stock granted will vest, and restrictions will terminate, on the later of (i) the first anniversary of the grant date, which was March 11, 2005, and (ii) the occurrence of a “Public Sale Date”, as defined in our Equity Participation Plan; but in no event later than the second anniversary of the date of grant. Notwithstanding this vesting schedule, the unvested shares of restricted stock will become fully vested upon death or disability of the employee, or if employment is terminated by us for reasons other than for “cause,” or if the employee elects to terminate employment with “good reason,” or

upon the occurrence of a “change of control,” as those terms are defined in the agreement with us governing the grant. In connection with the merger, each of Mariner’s executive officers has agreed, in exchange for a cash payment of $1,000, that his or her shares of restricted stock will not vest before the later of March 11, 2006 or ninety days after the effective date of the merger. For additional information regarding these special long-term grants, please see “ — Equity Participation Plan.”

		At December 31, 2005, the value of all restricted stock held by each named executive (based on the $17.75 trading price of our common stock on December 31, 2005) was as follows:

	covenants under Article III, (x) a Disqualifying Action of Spinco, Mariner or any of their respective Affiliates, (y) the inaccuracy of any factual statements or representations made by Mariner or Spinco in its representations letters to Counsel and (z) an action taken by Spinco, Mariner or any of their respective Affiliates which is not required or permitted by the Merger Agreement and which causes the Contribution, the Distribution or the Merger to be taxable; (iv) Mariner’s or Spinco’s portion of any Transfer Taxes determined pursuant to Section 2.4; and (v) any Taxes of Mariner and its Subsidiaries other than Taxes described in Section 2.1(a).
	(c) If the Indemnifying Party is required to indemnify the Indemnified Party pursuant to this Article II, the Indemnified Party shall submit its calculations of the amount required to be paid pursuant to this Article II, showing such calculations in sufficient detail so as to permit the Indemnifying Party to understand the calculations. Subject to the following two sentences, the Indemnifying Party shall pay to the Indemnified Party, no later than ten (10) business days after the Indemnifying Party receives the Indemnified Party’s calculations, the amount that the Indemnifying Party is required to pay the Indemnified Party under this Article II. If the Indemnifying Party disagrees with such calculations, it must notify the Indemnified Party of its disagreement in writing within thirty (30) business days of receiving such calculations.
	(d) Any claim under this Article II with respect to a Tax Liability must be made no later than thirty (30) days after the expiration of the applicable statute of limitations for assessment of such Tax Liability.
	(e) For all Tax purposes, the Forest Group and the Spinco Group agree to treat (i) any payment required by this Agreement as either a contribution by Forest to Spinco or a distribution by Spinco to Forest, as the case may be, occurring immediately prior to the Distribution and (ii) any payment of interest or non-federal Taxes by or to a Tax Authority as taxable or deductible, as the case may be, to the party entitled under this Agreement to retain such payment or required under this Agreement to make such payment, in either case except as otherwise mandated by applicable law or by a Final Determination.
	(f) The amount of any indemnification payment with respect to any Tax Liability shall be reduced by any current Tax Benefits actually realized by the Indemnified Party in respect of such Tax Liability by the end of the taxable year in which the indemnity payment is made. The calculation of such Tax Benefit shall be included in the calculation required to be submitted pursuant to Section 2.1(c). If, notwithstanding the treatment required by Section 2.1(e), any indemnification payment hereunder is determined to be taxable to the Indemnified Party by any Tax Authority, the indemnity payment payable by the Indemnifying Party shall be increased as necessary to ensure that, after all required Taxes on the indemnity payment are paid (including Taxes applicable to any increases in the indemnity payment under this Section 2.1(f)), the Indemnified Party receives the amount it would have received if the indemnity payment was not taxable.

	(b) Spinco shall prepare or cause to be prepared and file or cause to be filed all Tax Returns of Spinco for any Straddle Period (each a “Straddle Period Return”) on a basis consistent with the past practice of Forest with respect to the Spinco Business, except that Spinco may complete such Straddle Period Return in a manner that is not consistent with past practice if such Straddle Period Return preparation is allowed by law and such Straddle Period Return preparation does not adversely affect the Tax Liability of Forest or any of its Affiliates. If the Straddle Period Return reflects Taxes attributable to the Pre-Distribution Taxable Period, Spinco shall provide a copy of each such Straddle Period Return together with a computation of the pre-Distribution Taxes reflected in such Straddle Period Return (such computation, the “Statement”) to Forest for its review and comment not later than 30 days prior to the deadline for filing each such Straddle Period Return. Forest shall provide comments, if any, to Spinco at least 15 days prior to the deadline for filing such Straddle Period Return (the “15-Day Review Period”). Forest’s failure to notify Spinco of any disagreement prior to the end of the 15-Day Review Period shall indicate its concurrence with such Straddle Period Return and Statement. If Forest disagrees with the allocation in such Straddle Period Return and Statement, Forest shall notify Spinco in writing of such disagreement prior to the close of the 15-Day Review Period, and Forest and Spinco shall consult and attempt to resolve in good faith the disagreement.
	(c) Unless otherwise required by a Tax Authority, the parties hereby agree to prepare and file all Tax Returns, and to take all other actions, in a manner consistent with this Agreement. All Tax Returns shall be filed on a timely basis (taking into account applicable extensions) by the party responsible for filing such returns under this Agreement.
	(d) The party responsible for filing a Tax Return under this Section 2.3 is also responsible for paying to the relevant Tax Authority the amount of Tax Liability reflected on such Tax Return, subject to any indemnification rights it may have against the other party.

(a) Notwithstanding any other provisions hereof, if after the Distribution Date, an Indemnified Party or any of its Affiliates receives any notice, letter, correspondence, claim or decree from any Tax Authority (a “Tax Notice”) and, upon receipt of such Tax Notice, believes it has suffered or potentially could suffer any Tax Liability for which it is indemnified, the Indemnified Party shall promptly deliver such Tax Notice to the Indemnifying Party; provided, however, that the failure of the Indemnified Party to provide the Tax Notice to the Indemnifying Party shall not affect the indemnification rights of the Indemnified Party pursuant to this Article II, except to the extent that the Indemnifying Party is more than insignificantly prejudiced by the Indemnified Party’s failure to deliver such Tax Notice. The Indemnifying Party shall have the right to handle, defend, conduct and control, at its own expense, any Tax audit or other proceeding that relates to such Tax Notice (except to the extent that such Tax Notice,

Annex D-5

Table of Contents

	Tax audit or other proceeding relates to a Straddle Period, in which case there shall be joint control of the Tax audit); provided that, in all events, Forest shall have the right to participate, at its own expense, in any Tax audit or proceeding relating to Transaction Taxes. The Indemnifying Party shall also have the right to compromise or settle any such Tax audit or other proceeding that it has the authority to control pursuant to the preceding sentence subject, in the case of a compromise or settlement that would have a Material Adverse Effect on the Indemnified Party, to the Indemnified Party’s consent, which consent shall not be unreasonably withheld. If the Indemnifying Party fails within a reasonable time after notice to defend any such Tax Notice or the resulting audit or proceeding as provided herein, the Indemnifying Party shall be bound by the results obtained by the Indemnified Party in connection therewith. The Indemnifying Party shall pay to the Indemnified Party the amount of any Tax Liability within 15 days after a Final Determination of such Tax Liability.
	(b) If any adjustments shall be made to any Tax Returns related to Spinco or the Forest Group for any Pre-Distribution Taxable Period as a result of or in settlement of any audit, other administrative proceeding or judicial proceeding or as the result of the filing of an amended return to reflect the consequences of any determination made in connection with any such audit or proceeding or as required by an intervening change of law, Forest shall be liable for any additional Tax Liability and Forest shall be entitled to retain any Tax refund obtained.

	(i) Mariner or Spinco shall not take any action within its control, nor shall Mariner or Spinco permit any of its Affiliates to take any action within their control (including entering into any agreement, understanding or arrangement or any negotiations with respect to any transaction or series of transactions) that, or fail to take any action within its or their control the failure of which, would cause the Distribution to fail so to qualify (any such action or failure to act, a “Disqualifying Action”); provided, however, that the term “Disqualifying Action” as applied to Spinco or any of its Affiliates shall not include (x) any action, or failure to act, that is contemplated by the terms of the Distribution Agreement or the Merger Agreement or (y) any failure to take action to mitigate the effects of a breach by Spinco, occurring prior to the time of the Distribution, of a representation, warranty or covenant contained in the Distribution Agreement, regardless of whether such breach or its effects continue after the time of the Distribution.
	(ii) Forest shall not take, or fail to take any action that would result in, a Disqualifying Action; provided, however, that the term “Disqualifying Action” as applied to Forest shall not include any action, or failure to act, that is contemplated by the terms of the Distribution Agreement or the Merger Agreement.
	(iii) Prior to the first day following the second anniversary of the Distribution and except as otherwise provided in this Agreement, neither Spinco, Mariner, nor Forest shall take any action within its control, and neither Spinco, Mariner, nor Forest shall permit any of its Affiliates to take any action within their control (including entering into any agreement, understanding or arrangement or any negotiations with respect to any transaction or series of transactions) that, or fail to take any action within its or their control the failure of which (in both cases, including an action or failure to act that would be reasonably likely to be inconsistent with any representation made in the Tax Materials), would result in a more than immaterial possibility that the Distribution would be treated as part of a plan pursuant to which one or more persons acquire directly or indirectly Spinco stock or Forest stock representing a “50-percent or greater interest” within the meaning of Section 355(e)(4) of the Code (any such action or failure to act, a “Potential Disqualifying Action”), unless, prior to the taking of the Potential Disqualifying Action, (i) Mariner delivers to Forest, or Forest delivers to Mariner (as the case may be), either a ruling from the IRS (a “Ruling”) or an opinion from a nationally recognized law firm both reasonably acceptable to Forest (or to Mariner) (a “Subsequent Opinion”), in either case, to the effect that the Potential Disqualifying Action would not cause the Tax-Free Status of the Distribution to cease to apply to the Distribution, or (ii) Mariner and Forest mutually agree that such Potentially Disqualifying Action would not cause the Tax-Free Status of the Distribution to cease to apply to the Distribution.

	(i) Forest and its Affiliates shall cooperate with Mariner, and Mariner and its Affiliates shall cooperate with Forest (as the case may be), and shall take (or refrain from taking) all such actions as Mariner (or Forest) may reasonably request in connection with obtaining any ruling or opinion referred to in Section 3.2. Such cooperation shall include providing any information, representations and/or covenants reasonably requested by Mariner (or Forest) (or counsel for Mariner or Forest) to enable Mariner (or Forest) to obtain and maintain either a Subsequent Opinion or a Ruling. From and after any date on which Forest, Spinco, Mariner or any of their respective Affiliates makes any representation or covenant to counsel for purposes of obtaining a Subsequent Opinion or to the IRS for the purpose of obtaining a Ruling and (with respect solely to any representation given) until the first day after the second anniversary (or such later date as may be agreed upon at the time such representation is made) of the date of such Subsequent Opinion or Ruling, the party making such representation or covenant shall take no action that would have caused such representation to be untrue or covenant to be breached unless both parties determine, in their reasonable discretion, which discretion shall be exercised in good faith solely to preserve the Tax-Free Status of the Distribution, that such action would not cause the Tax-Free Status of the Distribution to cease to apply to the Distribution. Such representations and warranties, once made in writing, shall be considered Tax Materials subject to the provisions of Section 3.1.
	(ii) Neither Spinco, Mariner nor any of their respective Affiliates shall file any request for a Ruling with respect to the Tax-Free Status of the Distribution without the prior written consent of Forest, which consent shall not be unreasonably withheld or delayed, if a favorable Ruling would be reasonably likely to have an adverse effect on Forest or any of its Affiliates.

	(i) Subject to clause (iii) of this Section 3.3(c), until the first day after the second anniversary of the Distribution, Mariner shall give Forest, or Forest shall give Mariner (as the case may be), at least ten (10) days prior written notice of its or any of its Affiliates’ intention to effect any transaction with respect to such Person’s capital structure, whether through issuance, redemption or otherwise; provided, that Forest shall only be required to give Mariner notice of such a contemplated transaction if such transaction would result in more than an immaterial possibility of a Potential Disqualifying Action. Each such notice shall set forth the necessary terms and conditions of the proposed transaction, including, as applicable, the nature of any related action proposed to be taken, the approximate number of shares proposed to be issued, redeemed or transferred (directly or indirectly, in accordance with the provisions of Section 355(e) of the Code), the timetable for such action or transaction, and the number of shares otherwise then owned by the other party to the action or transaction (directly or indirectly, in accordance with the provisions of Section 355(e) of the Code), all with sufficient particularity to enable Forest (or Mariner) to review and comment on the effect of such transaction with respect to Section 355(e) of the Code. All information provided by any of the parties to the other parties pursuant to this Section 3.3 shall be kept confidential by the receiving parties to the same extent as that provided in Section 7.5 of the Distribution Agreement.
	(ii) If Mariner or any of its Affiliates, or Forest or any of its Affiliates (as the case may be), receives a Subsequent Opinion or Ruling, Mariner (or Forest) shall notify Forest (or Mariner) (if Forest

	the Subsequent Opinion or Ruling) promptly, but in any event within two (2) business days, after the receipt of the Subsequent Opinion or Ruling.

(iii) Notice shall not be required under (i) of this Section 3.3(c) with respect to the grant and/or exercise of any stock option, stock, stock-based compensation or other employment related arrangements arising in the ordinary course of business that have customary terms and conditions consistent with past practice (“Compensatory Transaction”) if the Compensatory Transaction satisfies the requirements of Treasury Regulation Section 1.355-7(d)(8), or, if in the case of options, if (A) the exercise price is equal to or greater than the fair market value of the stock subject to the option on the date of grant or issuance and (B) such option does not have a readily ascertainable fair market value within the meaning of Treasury Regulation Section 1.83-7.

Table of Contents

	(i) Reservoirs are considered proved if economic producibility is supported by either actual production or conclusive formation test. The area of a reservoir considered proved includes:

	(A) that portion delineated by drilling and defined by gas-oil and/or oil-water contacts, if any; and
	(B) the immediately adjoining portions not yet drilled, but which can be reasonably judged as economically productive on the basis of available geological and engineering data. In the absence of information on fluid contacts, the lowest known structural occurrence of hydrocarbons controls the lower proved limit of the reservoir.

	(ii) Reserves which can be produced economically through application of improved recovery techniques (such as fluid injection) are included in the “proved” classification when successful testing by a pilot project, or the operation of an installed program in the reservoir, provides support for the engineering analysis on which the project or program was based.

Annex F-6

	(iii) Estimates of proved reserves do not include the following:

	(A) oil that may become available from known reservoirs but is classified separately as “indicated additional reserves”;
	(B) crude oil, natural gas, and natural gas liquids, the recovery of which is subject to reasonable doubt because of uncertainty as to geology, reservoir characteristics, or economic factors;
	(C) crude oil, natural gas, and natural gas liquids, that may occur in undrilled prospects; and
	(D) crude oil, natural gas, and natural gas liquids, that may be recovered from oil shales, coal, gilsonite and other such sources.

	(i) Exercise Price. Subject to adjustment pursuant to Section 4(c) of the Plan, the purchase price per Share purchasable under an Option shall be determined by the Committee at the time the Option is granted, but shall not be less than the Fair Market Value per Share on the effective date of such grant.
	(ii) Time and Method of Exercise. The Committee shall determine and provide in the Award Agreement the time or times at which an Option may be exercised in whole or in part, and the method or methods by which, and the form or forms (which may include, without limitation, cash, check acceptable to the Company, Shares already-owned by the Participant for more than six months (unless such holding requirement is waived by the Committee), if the Shares are publicly traded, a “cashless-broker” exercise through procedures approved by the Company, or any combination thereof) in which payment of the exercise price with respect thereto may be made or deemed to have been made.
	(iii) Incentive Stock Options. An Incentive Stock Option may be granted only to an individual who is an employee of the Company or any parent or subsidiary corporation (as defined in section 424 of the Code) at the time the Option is granted and must be granted within 10 years from the date the Plan was approved by the Board or the shareholders, whichever is earlier. To the extent that the aggregate Fair Market Value (determined at the time the respective Incentive Stock Option is granted) of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by an individual during any calendar year under all incentive stock option plans of the Company and its parent and subsidiary corporations exceeds $100,000, or such Option fails to constitute an Incentive Stock Option for any reason, such purported Incentive Stock Options shall be treated as Non-Qualified Stock Options. The Committee shall determine, in accordance with applicable provisions of the Code, Treasury Regulations and other administrative pronouncements, which of a Participant’s purported Incentive Stock Options do not constitute Incentive Stock Options and shall notify the Participant of such determination as soon as reasonably practicable after such determination. No Incentive Stock Option shall be granted to an individual if, at the time the Option is granted, such individual owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or of its parent or subsidiary corporation, within the meaning of section 422(b)(6) of the Code, unless (i) at the time such Option is granted the option price is at least 110% of the Fair Market Value of the Common Stock subject to the Option and (ii) such Option by its terms is not exercisable after the

Annex G-3

Table of Contents

expiration of five years from the date of grant. An Incentive Stock Option shall not be transferable otherwise than by will or the laws of descent and distribution, and shall be exercisable during the Participant’s lifetime only by such Participant or the Participant’s guardian or legal representative. The terms of any Incentive Stock Option granted under the Plan shall comply in all respects with the provisions of Section 422 of the Code, or any successor provision, and any regulations promulgated thereunder.

	(i) Dividends. Dividends paid on Restricted Stock may be paid directly to the Participant, may be subject to risk of forfeiture and/or transfer restrictions during any period established by the Committee or sequestered and held in a bookkeeping cash account (with or without interest) or reinvested on an immediate or deferred basis in additional shares of Common Stock, which credit or shares may be subject to the same restrictions as the underlying Award or such other restrictions, all as determined by the Committee in its discretion, as provided in the Award Agreement.
	(ii) Registration. Any Restricted Stock may be evidenced in such manner as the Committee shall deem appropriate, including, without limitation, book-entry registration or issuance of a stock certificate or certificates. In the event any stock certificate is issued in respect of Restricted Stock granted under the Plan, such certificate shall be registered in the name of the Participant and shall bear an appropriate legend referring to the terms, conditions, and restrictions applicable to such Restricted Stock.
	(iii) Forfeiture and Restrictions Lapse. Except as otherwise determined by the Committee or the terms of the Award Agreement that granted the Restricted Stock, upon termination of a Participant’s employment for any reason during the applicable Restricted Period, all Restricted Stock shall be forfeited by the Participant without payment and re-acquired by the Company. The Committee may, when it finds that a waiver would be in the best interests of the Company, waive in whole or in part any or all remaining restrictions with respect to such Participant’s Restricted Stock, provided, however, if the Award is intended to qualify as performance based compensation under Section 162(m) of the Code, such waiver may be only upon an event permitted under Section 162(m) of the Code or the regulations thereunder. Unrestricted Shares, evidenced in such manner as the Committee shall deem appropriate, shall be issued to the holder of Restricted Stock promptly after the applicable restrictions have lapsed or otherwise been satisfied.
	(iv) Transfer Restrictions. During the Restricted Period, Restricted Stock will be subject to such limitations on transfer as necessary to comply with Section 83 of the Code.

	(i) Awards May Be Granted Separately or Together. Awards may, in the discretion of the Committee, be granted either alone or in addition to, in tandem with, any other Award granted under the Plan or any award granted under any other plan of the Company or any Parent Entity or Subsidiary. Awards granted in addition to or in tandem with other Awards or awards granted under any other plan of the Company or any Parent Entity or Subsidiary may be granted either at the same time as or at a different time from the grant of such other Awards or awards.
	(ii) Limits on Transfer of Awards.

	(A) Except as provided in paragraph (C) below, each Award, and each right under any Award, shall be exercisable only by the Participant during the Participant’s lifetime, or if permissible under applicable law, by the Participant’s guardian or legal representative as determined by the Committee.

Annex G-4

Table of Contents

	(B) Except as provided in paragraph (C) below, no Award and no right under any such Award may be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a Participant other than by will or by the laws of descent and distribution, and any such purported prohibited assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the Company or any Parent Entity or Subsidiary.
	(C) To the extent specifically approved in writing by the Committee, an Award (other than an Incentive Stock Option) may be transferred to immediate family members or related family trusts, limited partnerships or similar entities or other Persons on such terms and conditions as the Committee may establish or approve in its sole discretion.

	(iii) Terms of Awards. The term of each Award shall be for such period as may be determined by the Committee, provided the term of an Incentive Stock Option shall be limited as provided in Section 6(a)(iii).
	(iv) Share Restrictions. All Shares or other securities of the Company or any Subsidiary delivered under the Plan pursuant to any Award or the exercise thereof shall be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan or the rules, regulations, and other requirements of the SEC, any stock exchange upon which such Shares or other securities are then listed, and any applicable federal or state laws, and if certificates are issued for the Shares, the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions.
	(v) Consideration for Grants. Awards may be granted for no cash consideration or for such consideration as the Committee determines including, without limitation, such minimal cash consideration as may be required by applicable law.
	(vi) Delivery of Shares or other Securities and Payment by Participant of Consideration. No Shares or other securities shall be delivered pursuant to any Award until payment in full of any amount required to be paid pursuant to the Plan or the applicable Award Agreement (including, without limitation, any exercise price or tax withholding) is received by the Company. Such payment may be made by such method or methods and in such form or forms as the Committee shall determine, including, without limitation, cash, Shares, other securities, other Awards or other property, withholding of Shares, cashless exercise with simultaneous sale, or any combination thereof, provided that the combined value, as determined by the Committee, of all cash and cash equivalents and the Fair Market Value of any such Shares or other property so tendered to the Company, as of the date of such tender, is at least equal to the full amount required to be paid pursuant to the Plan or the applicable Award Agreement to the Company.
	(vii) Unusual Transactions or Events. In the event of any distribution (whether in the form of cash, Shares, other securities, or other property), recapitalization, reorganization, merger, spin-off, split-off, split-up, consolidation, combination, repurchase, or exchange of Shares or other securities of the Company, or other relevant corporate transaction or event or any unusual or nonrecurring transactions or events affecting the Company or any affiliate of the Company, and whenever the Committee determines that action is appropriate in order to prevent the dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan or with respect to any Award under the Plan, to facilitate such transactions or events, the Committee, in its sole discretion and on such terms and conditions as it deems appropriate, may take any one or more of the following actions:

(A) To provide for either (i) the termination of any such Award in exchange for an amount of cash, if any, equal to the amount that would have been attained upon the exercise of such Award or realization of the Participant’s rights (and, for the avoidance of doubt, if as of the date of the occurrence of such transaction or event the Committee determines in good faith that no amount would have been attained upon the exercise of such Award or realization of the Participant’s rights, then such Award may be terminated by the Company without payment) or (ii) the replacement of such Award with other rights or property selected by the Committee in its sole discretion;

	(B) To provide that such Award be assumed by the successor or survivor corporation, or a parent or subsidiary thereof, or shall be substituted for by similar options, rights or awards covering the stock of the successor or survivor corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the number and kind of shares and prices;
	(C) To make adjustments in the number and type of shares of common Stock (or other securities or property) subject to outstanding Awards, and in the number and kind of outstanding Awards and/or in the terms and conditions of (including the grant or exercise price), and the criteria included in, outstanding Awards and Awards which may be granted in the future, and in the maximum number of shares with respect to which Options or Restricted Stock may be granted to an Employee during the term of the Plan; and
	(D) To provide that such Award shall be exercisable or payable or fully vested with respect to all Shares covered thereby, notwithstanding anything to the contrary in the Plan or the applicable Award Agreement.

	(i) Amendments to the Plan. The Board or the Committee may amend, alter, suspend, discontinue, or terminate the Plan without the consent of any stockholder, Participant, other holder or beneficiary of an Award, or other Person; provided, however, notwithstanding any other provision of the Plan or any Award Agreement, without the approval of the stockholders of the Company (i) no such amendment, alteration, suspension, discontinuation, or termination shall be made that would increase the total number of Shares that may be issued under Awards granted under the Plan, except as provided in Section 4(c) of the Plan, or (ii) permit the exercise price of any outstanding Option that is “underwater” to be reduced or for an “underwater” Option to be cancelled and replaced with a new Award; provided further, however, no such amendment, alteration, suspension, discontinuation, or termination shall materially adversely affect the rights of a Participant under an Award without the consent of such Participant.
	(ii) Amendments to Awards. Subject to clause (i) above, the Committee may waive any conditions or rights under, amend any terms of, or alter any Award theretofore granted, provided no change in any Award shall materially adversely affect the rights of a Participant under the Award without the consent of such Participant. Notwithstanding the foregoing, with respect to any Award intended to qualify as performance-based compensation under Section 162(m) of the Code, no adjustment other than an acceleration of vesting or payment upon the Participant’s death, disability or change of control of the Company, shall be authorized to the extent such adjustment would cause the Award to fail to so qualify.
	(iii) Compliance. Notwithstanding the foregoing, the Committee may make any amendment to the Plan or an Award Agreement that it believes necessary or helpful to comply with any applicable law, including without limitation, Section 409A of the Code.
