This Agreement and Plan of Merger (this “Agreement”) dated January 7, 2007, by and among Forest Oil Corporation, a New York corporation (“Parent”), MJCO Corporation, a Delaware corporation and a wholly owned Subsidiary of Parent (“Merger Sub”), and The Houston Exploration Company, a Delaware corporation (the “Company”).

WHEREAS, the respective Boards of Directors of Parent, Merger Sub and the Company deem it advisable and in the best interests of their respective corporations and stockholders that a transaction be effected pursuant to which (i) Merger Sub will merge with and into the Company, with the Company continuing as the surviving corporation, (ii) immediately thereafter, the Company will merge with and into Parent, with Parent continuing as the surviving corporation (the “Mergers”), and (iii) subject to the provisions of Article II, Parent will pay aggregate consideration equal to 0.84 shares of Parent Common Stock and $26.25 cash for each outstanding share of Company Common Stock at the Merger I Effective Time (with specific per share consideration determined as a result of the election, pro ration, equalization and other provisions of Article II), upon the terms and subject to the conditions set forth herein, and such Boards of Directors have approved the Agreement and the Mergers; and

WHEREAS, for U.S. federal income tax purposes, it is intended that the Mergers will qualify as a reorganization under the provisions of Section 368(a) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”);

NOW, THEREFORE, in consideration of the premises and the representations, warranties and agreements contained herein, the parties hereto agree as follows:

2.1 Effect of the First Merger on Capital Stock. At the Merger I Effective Time, by virtue of the First Merger and without any action on the part of any party or the holder of any of their securities:

(a) Capital Stock of Merger Sub. Each share of capital stock of Merger Sub issued and outstanding immediately prior to the Merger I Effective Time shall be converted into one share of common stock, par value $0.01 per share, of the Merger I Surviving Entity, so that, after the Merger I Effective Time, Parent shall be the holder of all of the issued and outstanding shares of the Merger I Surviving Entity’s common stock.

(b) Capital Stock of the Company. Subject to the other provisions of this Article II, each share of common stock of the Company, par value $0.01 per share (the “Company Common Stock”) issued and outstanding immediately prior to the Merger I Effective Time (excluding any shares of Company Common Stock described in Section 2.1(d) and any Appraisal Shares) shall be converted into the right to receive at the election of the holder thereof as provided in and subject to the provisions of Section 2.3, either (i) the Per Share Stock Consideration or (ii) the Per Share Cash Consideration (the Per Share Cash Consideration together with the Per Share Stock Consideration, are herein referred to as the “Merger Consideration”).

For purposes of this Agreement:

“Aggregate Consideration” shall mean the sum of (x) the Total Stock Value and (y) the Total Cash Amount.

“Aggregate Consideration Per Share” shall mean the quotient, rounded to the nearest ten-thousandth, obtained by dividing the Aggregate Consideration by the total number of shares of Company Common Stock outstanding immediately prior to the Merger I Effective Time.

“Deemed Shares Outstanding” shall mean the total number of shares of Company Common Stock outstanding immediately prior to the Merger I Effective Time, provided, however, that regardless of the actual number of shares of Company Common Stock outstanding immediately prior to the Merger I Effective Time, in no event shall the Deemed Shares Outstanding exceed the sum of (i) 28,140,054, and (ii) the aggregate number of shares of Company Common Stock, if any, issued by the Company after the date hereof upon the exercise of the Company Options outstanding as of the date hereof which have been disclosed to Parent prior to the date hereof and which are referred to in Section 3.2 or pursuant to Section 5.1(d)(B) in accordance with the terms of such options.

“Exchange Ratio” shall mean the quotient, rounded to the nearest ten-thousandth, obtained by dividing the Aggregate Consideration Per Share by the Final Parent Stock Price.

“Final Parent Stock Price” shall mean the average of the per share closing sales prices of Parent Common Stock on the New York Stock Exchange (the “New York Stock Exchange”), as reported in The Wall Street Journal, during the Valuation Period.

“Parent Common Stock” shall mean the common stock of Parent, par value $0.01 per share.

“Per Share Cash Consideration” shall mean cash in an amount equal to the value of the Aggregate Consideration Per Share.

“Per Share Stock Consideration” shall mean a number of shares (which need not be a whole number) of Parent Common Stock equal to the Exchange Ratio, which shares shall include the Parent Rights associated therewith.

“Total Cash Amount” shall mean (x) the product obtained by multiplying (A) $52.4580 by (B) 50.04% of the Deemed Shares Outstanding minus (y) any cash dividends to all stockholders made by the Company after the date of this Agreement.

“Total Stock” shall mean the product obtained by multiplying (x) 1.6813 by (y) 49.96% of the Deemed Shares Outstanding.

“Total Stock Value” shall mean the product obtained by multiplying (x) the Total Stock by (y) the Final Parent Stock Price.

“Valuation Period” shall mean the ten consecutive trading days during which the shares of Parent Common Stock are traded on the New York Stock Exchange ending on (and including)

the third calendar day immediately prior to the Merger I Effective Time, or if such calendar day is not a trading day, then ending on the trading day immediately preceding such calendar day.

(c) Certificates. All such shares of Company Common Stock, when so converted, shall cease to be outstanding and shall automatically be canceled and cease to exist. Each holder of a certificate (a “Certificate”) previously representing any such shares shall cease to have any rights with respect thereto, except the right to receive (x) the Merger Consideration, (y) any dividends or other distributions in accordance with Section 2.6, and (z) any cash to be paid in lieu of any fractional shares of Parent Common Stock in accordance with Section 2.6, in each case to be issued or paid in consideration therefor upon the surrender of such Certificates in accordance with Section 2.6.

(d) Treasury Stock. All shares of Company Common Stock held by the Company as treasury shares or by Parent or Merger Sub or by any wholly owned Subsidiary of Parent, Merger Sub or the Company immediately prior to the Merger I Effective Time shall automatically be canceled and cease to exist as of the Merger I Effective Time and no consideration shall be delivered or deliverable therefor.

(e) Calculations. The calculations required by Section 2.1(b) shall be prepared by Parent promptly after the Closing.

(f) Impact of Stock Splits, Etc. If, between the date of this Agreement and the Merger I Effective Time, the shares of Parent Common Stock or Company Common Stock shall be changed or proposed to be changed into a different number or class of shares by reason of the occurrence of or record date with respect to any reclassification, recapitalization, split-up, combination, exchange of shares or similar readjustment, in any such case within such period, or a stock dividend thereon shall be declared with a record date within such period, appropriate adjustments shall be made to the Per Share Stock Consideration. Nothing in this Section 2.1(f) shall be construed to permit any party to take any action that is otherwise prohibited or restricted by any other provision of this Agreement.

2.2 Effect of the Second Merger on Capital Stock. At the Merger II Effective Time, by virtue of the Second Merger and without any action on the part of any party or the holder of any of their securities:

(a) Capital Stock of Merger I Surviving Entity. All outstanding shares of the Merger I Surviving Entity shall be cancelled and shall cease to exist and no stock of Parent, cash or other consideration shall be issued or delivered in exchange therefor.

(b) Capital Stock of Parent. The issued and outstanding shares of capital stock of Parent shall remain issued and outstanding and unchanged.

2.3 Election Procedures.

(a) An election form and other appropriate and customary transmittal materials (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates theretofore representing shares of Company Common Stock shall pass, only upon proper delivery of such Certificates to the Exchange Agent) in such form as Parent shall specify

and as shall be reasonably acceptable to the Company (the “Election Form”) and pursuant to which each holder of record of shares of Company Common Stock as of the close of business on the Election Form Record Date may make an election pursuant to this Section 2.3, shall be mailed at the same time as the Proxy Statement or at such other time as the Company and Parent may agree (the date on which such mailing is commenced or such other agreed date, the “Mailing Date”) to each holder of record of Company Common Stock as of the close of business on the record date for notice of the Company Special Meeting (the “Election Form Record Date”).

(b) Each Election Form shall permit the holder (or the beneficial owner through appropriate and customary documentation and instructions), other than any holder of Appraisal Shares, to specify (i) the number of shares of such holder’s Company Common Stock with respect to which such holder elects to receive the Per Share Stock Consideration (“Stock Election Shares”), (ii) the number of shares of such holder’s Company Common Stock with respect to which such holder elects to receive the Per Share Cash Consideration (“Cash Election Shares”), or (iii) that such holder makes no election with respect to such holder’s Company Common Stock (“No Election Shares”). Any Company Common Stock with respect to which the Exchange Agent has not received an effective, properly completed Election Form on or before 5:00 p.m., New York time, on the 33rd day following the Mailing Date (or such other time and date as the Company and Parent shall agree) (the “Election Deadline”) (other than any shares of Company Common Stock that constitute Appraisal Shares as of such time) shall also be deemed to be No Election Shares. If the Closing has not occurred within 10 days of the Election Deadline, then, unless the Closing is then scheduled to take place by the tenth day thereafter, the Election Deadline shall be changed, unless Parent and the Company agree that no such change shall be made, to such tenth day, or such other date as is agreed to by Parent and the Company, and the Company and Parent shall make a public announcement of such new Election Deadline, if any.

(c) Parent shall make available one or more Election Forms as may reasonably be requested from time to time by all Persons who become holders (or beneficial owners) of Company Common Stock between the Election Form Record Date and the close of business on the Business Day prior to the Election Deadline, and the Company shall provide to the Exchange Agent all information reasonably necessary for it to perform as specified herein.

(d) Any such election shall have been properly made only if the Exchange Agent shall have actually received a properly completed Election Form by the Election Deadline. An Election Form shall be deemed properly completed only if accompanied by (i) one or more Certificates (or customary affidavits and indemnification regarding the loss or destruction of such Certificates or the guaranteed delivery of such Certificates) representing all certificated shares of Company Common Stock covered by such Election Form or (ii) in the case of shares in book-entry form, any additional documents specified by the procedures set forth in the Election Form, together with duly executed transmittal materials included in the Election Form. Any Election Form may be revoked or changed by the Person submitting such Election Form prior to the Election Deadline. In the event an Election Form is revoked prior to the Election Deadline, the shares of Company Common Stock represented by such Election Form shall become No Election Shares and Parent shall cause the Certificates, if any, representing Company Common Stock to be promptly returned without charge to the Person submitting the Election Form upon

written request to that effect from the holder who submitted the Election Form, except to the extent (if any) a subsequent election is properly made with respect to any or all of the applicable shares of Company Common Stock. Subject to the terms of this Agreement and of the Election Form, the Exchange Agent shall have reasonable discretion to determine whether any election, revocation or change has been properly or timely made and to disregard immaterial defects in the Election Forms, and any good faith decisions of the Exchange Agent regarding such matters shall be binding and conclusive. None of Parent, Merger Sub or the Exchange Agent shall be under any obligation to notify any Person of any defect in an Election Form.

(e) Within ten Business Days after the Election Deadline, unless the Merger I Effective Time has not yet occurred, in which case as soon after the Merger I Effective Time as practicable (and in no event more than ten Business Days after the Merger I Effective Time), Parent shall cause the Exchange Agent to effect the allocation among the holders of Company Common Stock of rights to receive Parent Common Stock or cash in the Merger in accordance with the Election Forms as follows:

(i) Cash Election Shares More Than Total Cash Amount. If the product obtained by multiplying (x) the Cash Election Shares by (y) the Per Share Cash Consideration is greater than the Total Cash Amount, then:

(A) all Stock Election Shares and No Election Shares shall be converted into the right to receive the Per Share Stock Consideration,

(B) the Exchange Agent shall then select from among the Cash Election Shares, pro rata to the holders of Cash Election Shares in accordance with their respective numbers of Cash Election Shares (except as provided in the last paragraph of Section 2.3(e)), a sufficient number of shares (“Stock Designated Shares”) such that the aggregate cash amount that will be paid in the Mergers equals as closely as practicable the Total Cash Amount, and all Stock Designated Shares shall be converted into the right to receive the Per Share Stock Consideration, and

(C) the Cash Election Shares that are not Stock Designated Shares will be converted into the right to receive the Per Share Cash Consideration.

(ii) Cash Election Shares Less Than Total Cash Amount. If the product obtained by multiplying (x) the Cash Election Shares by (y) the Per Share Cash Consideration is less than the Total Cash Amount, then:

(A) all Cash Election Shares shall be converted into the right to receive the Per Share Cash Consideration,

(B) the Exchange Agent shall then select first from among the No Election Shares and then (if necessary) from among the Stock Election Shares, in each case pro rata to the holders of No Election Shares or Stock Election Shares, as the case may be, in accordance with their respective numbers of No Election Shares or Stock Election Shares, as the case may

be, a sufficient number of shares (“Cash Designated Shares”) such that the aggregate cash amount that will be paid in the Mergers equals as closely as practicable the Total Cash Amount, and all Cash Designated Shares shall be converted into the right to receive the Per Share Cash Consideration, and

(C) the Stock Election Shares and the No Election shares that are not Cash Designated Shares shall be converted into the right to receive the Per Share Stock Consideration.

(iii) Cash Election Shares Equal to Total Cash Amount. If the product obtained by multiplying (x) the Cash Election Shares by (y) the Per Share Cash Consideration is equal to the Total Cash Amount, then subparagraphs (i) and (ii) above shall not apply and all Cash Election Shares shall be converted into the right to receive the Per Share Cash Consideration and all Stock Election Shares and No Election Shares shall be converted into the right to receive the Per Share Stock Consideration.

Notwithstanding anything in this Agreement to the contrary, to the fullest extent permitted by Law, for purposes of determining the allocations set forth in this Section 2.3, Parent shall have the right to require, but not the obligation to require (unless such requirement is necessary to satisfy the conditions set forth in Section 6.2(d) or Section 6.3(d)), that any shares of Company Common Stock that constitute Appraisal Shares as of the Election Deadline be treated as Cash Election Shares not subject to the pro rata selection process contemplated by this Section 2.3, and, if Parent so requires, then, to the fullest extent permitted by Law, any Appraisal Shares that receive the Merger Consideration shall be treated as Cash Election Shares not subject to the pro rata selection process contemplated by this Section 2.3.

(f) The pro rata selection process to be used by the Exchange Agent shall consist of such equitable pro ration processes as shall be mutually determined by Parent and the Company.

2.4 Appraisal Rights. Notwithstanding anything in this Agreement to the contrary, if appraisal rights are available under Delaware law, shares of Company Common Stock issued and outstanding immediately prior to the Merger I Effective Time that are held by any record holder who is entitled to demand and properly demands appraisal of such shares pursuant to, and who complies in all respects with, the provisions of Section 262 of the DGCL (the “Appraisal Shares”) shall not be converted into the right to receive the Merger Consideration payable pursuant to Section 2.3, but instead at the Merger I Effective Time shall become the right to payment of the fair value of such shares in accordance with the provisions of Section 262 of the DGCL and at the Merger I Effective Time, all Appraisal Shares shall no longer be outstanding and shall automatically be canceled and cease to exist. Notwithstanding the foregoing, if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Section 262 of the DGCL or a court of competent jurisdiction shall determine that such holder is not entitled to the relief provided by Section 262 of the DGCL, then the right of such holder to be paid the fair value of such holder’s Appraisal Shares under Section 262 of the DGCL shall be forfeited and cease and if such forfeiture shall occur following the Election Deadline, each of such holder’s Appraisal Shares shall be deemed to have been converted at the

Merger I Effective Time into, and shall have become, the right to receive without interest thereon, the Merger Consideration into which No Election Shares shall have been converted pursuant to Section 2.3(e), subject to the last sentence of Section 2.3(e). The Company shall deliver prompt notice to Parent of any demands for appraisal of any shares of Company Common Stock and provide Parent with the opportunity to participate in all negotiations and proceedings with respect to demands for appraisal under the DGCL. Prior to the Merger I Effective Time, the Company shall not, without the prior written consent of Parent, make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing.

2.5 Treatment of Stock Options; Restricted Stock; Company Awards.

(a) Prior to the Merger I Effective Time, the Company, the Company Board and the Compensation Committee of the Company Board (the “Committee”) shall take all actions necessary under the Company’s 1996 Stock Option Plan (the “1996 Plan”), the Company’s 1999 Non-Qualified Stock Option Plan (the “1999 Plan”), the Company’s 2002 Long-Term Incentive Plan (the “2002 Plan”) and the Company’s 2004 Long-Term Incentive Plan (the “2004 Plan” and, together with the 1996 Plan, the 1999 Plan and the 2002 Plan, the “Stock Plans”) to cause each holder of an option to purchase shares of Company Common Stock granted under a Stock Plan, which option is outstanding immediately prior to the Merger I Effective Time (a “Company Option”), to have the right to exercise such Company Option in full (whether or not vested) immediately prior to the Merger I Effective Time pursuant to procedures to be established by the Committee. To the extent any Company Option that has an exercise price per share that is equal to or greater than the Per Share Cash Consideration is not so exercised immediately prior to the Merger I Effective Time, such Company Option shall be cancelled at the Merger I Effective Time for no consideration by virtue of the Mergers and without any action on the part of the holder thereof, the Company, Parent or Merger Sub. To the extent any Company Option that has an exercise price per share that is less than the Per Share Cash Consideration is not so exercised immediately prior to the Merger I Effective Time (the “In-the-Money Company Options”), such In-the-Money Company Option shall, by virtue of the Mergers and without any action on the part of the holder thereof, the Company, Parent or Merger Sub, be cancelled and converted into the right to receive, from the Surviving Entity, as soon as practicable following the Merger I Effective Time, an amount in cash (less any applicable withholding Taxes and without interest) equal to the product of (i) the excess of (A) the Per Share Cash Consideration over (B) the per share exercise price of Company Common Stock subject to such In-the-Money Company Option, multiplied by (ii) the number of shares of Company Common Stock subject to such In-the-Money Company Option immediately prior to the Merger I Effective Time (whether or not vested). As of the Merger I Effective Time, all Company Options shall no longer be outstanding and shall automatically cease to exist, and each holder of a Company Option shall cease to have any rights with respect thereto, except, with respect to In-the-Money Company Options, the right to receive the payment described in the immediately preceding sentence. Prior to the Merger I Effective Time, the Company, the Company Board and the Committee shall take all actions necessary under the Stock Plans, the award agreements thereunder and otherwise to effectuate the provisions of this Section 2.5(a), including providing notice to the holders of Company Options of such provisions.

(b) Subject to the terms and upon the conditions herein, as of the Merger I Effective Time, the restrictions on each restricted share of Company Common Stock (the “Company Restricted Stock”) granted and then outstanding under the Stock Plans shall, and without any action on the part of the holder thereof, the Company, Parent or Merger Sub, lapse immediately prior to the Merger I Effective Time, and each such share of Company Restricted Stock shall be fully vested in each holder thereof at such time, and each such share of Company Restricted Stock will be treated at the Merger I Effective Time the same as, and have the same rights and be subject to the same conditions, as each share of Company Common Stock not subject to any restrictions; provided, that upon vesting the holder may satisfy the applicable withholding Tax obligations by returning to the Surviving Entity or Parent a sufficient number of shares of Company Common Stock equal in value to such obligation. Prior to the Merger I Effective Time, the Company, the Company Board and the Committee shall take all actions necessary under the Stock Plans, the award agreements thereunder and otherwise to effectuate this Section 2.5(b).

(c) Subject to the terms and upon the conditions herein, immediately prior to the Merger I Effective Time, each restricted stock unit award granted and then outstanding under the Stock Plans (each, a “Company Award”) shall be fully vested in each holder thereof and the underlying shares of Company Common Stock shall be issued and will be treated at the Merger I Effective Time the same as, and shall have the same rights and be subject to the same conditions as, other shares of Company Common Stock; provided that upon vesting and issuance, the holder may satisfy the applicable withholding Tax obligations by returning to the Surviving Entity or Parent a sufficient number of shares of Company Common Stock equal in value to such obligation. Prior to the Merger I Effective Time, the Company, the Company Board and the Committee shall take all actions necessary under the Stock Plans, the award agreements thereunder and otherwise to effectuate this Section 2.5(c).

(d) Except as contemplated by clauses (a), (b) and (c) above, the Surviving Entity and Parent shall be entitled to deduct and withhold, or cause the Exchange Agent to deduct and withhold, from the consideration otherwise payable pursuant to this Section 2.5 to any holders of Company Options, Company Restricted Stock or Company Awards such amounts as it may be required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign Tax Law. To the extent that amounts are so withheld by the Surviving Entity, Parent or the Exchange Agent, as the case may be, the withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holders of Company Options, Company Restricted Stock or Company Awards, as applicable, in respect of which the deduction and withholding was made by the Surviving Entity, Parent or the Exchange Agent, as the case may be.

2.6 Exchange of Certificates.

(a) Exchange Agent. Prior to the Merger I Effective Time, Parent shall deposit, or shall cause to be deposited, with the Company’s transfer agent or a bank or trust company designated by Parent and reasonably satisfactory to the Company (the “Exchange Agent”), for the benefit of the holders of shares of Company Common Stock, for exchange in accordance with this Article II, through the Exchange Agent, sufficient cash and Parent Common Stock to make pursuant to this Article II all deliveries of cash and Parent Common Stock as

required by this Article II. Parent agrees to make available to the Exchange Agent, from time to time as needed, cash sufficient to pay any dividends and other distributions pursuant to Section 2.6(c) and to make payments in lieu of fractional shares pursuant to Section 2.6(e). Any cash and Parent Common Stock deposited with the Exchange Agent (including as payment for fractional shares in accordance with Section 2.6(e) and any dividends or other distributions in accordance with Section 2.6(c)) shall hereinafter be referred to as the “Exchange Fund.” The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Merger Consideration contemplated to be paid for shares of Company Common Stock pursuant to this Agreement out of the Exchange Fund. Except as contemplated by Sections 2.6(c) and 2.6(e) hereof, the Exchange Fund shall not be used for any other purpose.

(b) Exchange Procedures. Promptly after the Merger I Effective Time, Parent shall instruct the Exchange Agent to mail to each record holder, as of the Merger I Effective Time, of an outstanding Certificate that immediately prior to the Merger I Effective Time represented shares of Company Common Shares (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent, and shall be in customary form and agreed to by Parent and the Company prior to the Merger I Effective Time) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration payable in respect of the shares of Company Common Stock represented by such Certificates. Promptly after the Merger I Effective Time, upon surrender of Certificates for cancellation to the Exchange Agent together with such letters of transmittal, properly completed and duly executed, and such other documents as may be required pursuant to such instructions, the holders of such Certificates and the holders of Certificates who previously surrendered Certificates to the Exchange Agent with properly completed and duly executed Election Forms shall be entitled to receive in exchange therefor (A) shares of Parent Common Stock representing, in the aggregate, the whole number of shares of Parent Common Stock that such holder has the right to receive pursuant to Section 2.3 (after taking into account all shares of Company Common Stock then held by such holder) and (B) a check in the amount equal to the aggregate amount of cash that such holder has the right to receive pursuant to Section 2.3 and this Article II, including cash payable in lieu of any fractional Parent Common Stock pursuant to Section 2.6(e) and dividends and other distributions pursuant to Section 2.6(c). No interest shall be paid or accrued on any Merger Consideration, cash in lieu of fractional shares or on any unpaid dividends and distributions payable to holders of Certificates. In the event of a transfer of ownership of shares of Company Common Stock which is not registered in the transfer records of the Company, the Merger Consideration payable in respect of such shares of Company Common Stock may be paid to a transferee if the Certificate representing such shares of Company Common Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and the Person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other Taxes required by reason of the delivery of the Merger Consideration in any name other than that of the registered holder of the Certificate surrendered, or shall establish to the satisfaction of the Exchange Agent that such Taxes have been paid or are not payable. Until surrendered as contemplated by this Section 2.6, each Certificate other than Certificates representing Appraisal Shares shall be deemed at any time after the Merger I Effective Time to represent only the right to receive upon such surrender the Merger Consideration payable in respect of the shares of Company Common Stock represented by such Certificate, cash in lieu of any fractional Parent Common Stock to which such holder is entitled

pursuant to Section 2.6(e) and any dividends or other distributions to which such holder is entitled pursuant to Section 2.6(c).

(c) Distributions with Respect to Unexchanged Parent Common Stock. No dividends or other distributions declared or made with respect to Parent Common Stock with a record date after the Merger I Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the Parent Common Stock that such holder would be entitled to receive upon surrender of such Certificate and no cash payment in lieu of fractional Parent Common Stock shall be paid to any such holder until such holder shall surrender such Certificate in accordance with this Section 2.6. Subject to applicable Law, following surrender of any such Certificate, there shall be paid to such holder of Parent Common Stock issuable in exchange therefor, without interest, (i) promptly after the time of such surrender, the amount of any cash due pursuant to Section 2.3 and cash payable in lieu of fractional Parent Common Stock to which such holder is entitled pursuant to Section 2.6(e) and the amount of dividends or other distributions with a record date after the Merger I Effective Time theretofore paid with respect to the Parent Common Stock and payable with respect to such Parent Common Stock, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Merger I Effective Time but prior to such surrender and a payment date subsequent to such surrender payable with respect to such Parent Common Stock.

(d) Further Rights in Company Common Shares. The Merger Consideration issued upon conversion of a share of Company Common Stock in accordance with the terms hereof (including any cash paid pursuant to Section 2.6(c) or Section 2.6(e)) shall be deemed to have been issued in full satisfaction of all rights pertaining to such share of Company Common Stock.

(e) Fractional Shares. No certificates or scrip or Parent Common Stock representing fractional Parent Common Stock or book entry credit of the same shall be issued upon the surrender for exchange of Certificates, and such fractional share interests will not entitle the owner thereof to vote or to have any rights as a holder of any Parent Common Stock. Notwithstanding any other provision of this Agreement, each holder of shares of Company Common Stock exchanged in the Merger who would otherwise have been entitled to receive a fraction of a Parent Common Stock (after taking into account all Certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to the product of (i) the average of the closing sale prices of Parent Common Stock on the NYSE as reported by The Wall Street Journal for the five trading days immediately preceding the date on which the Merger I Effective Time shall occur and (ii) the fraction of a Parent Common Stock that such holder would otherwise be entitled to receive pursuant to Section 2.3 hereof. As promptly as practicable after the determination of the amount of cash, if any, to be paid to holders of fractional interests, the Exchange Agent shall so notify Parent, and Parent shall, or shall cause the Surviving Entity to, deposit such amount with the Exchange Agent and shall cause the Exchange Agent to forward payments to such holders of fractional interests subject to and in accordance with the terms hereof.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of Company Common Stock after 180 days following the Merger I Effective Time occurs shall be delivered to Parent upon demand and, from and after

such delivery to Parent, any former holders of Company Common Stock (other than Appraisal Shares) who have not theretofore complied with this Article II shall thereafter look only to Parent for the Merger Consideration payable in respect of such shares of Company Common Stock, any cash in lieu of fractional Parent Common Stock to which they are entitled pursuant to Section 2.6(e) and any dividends or other distributions with respect to Parent Common Stock to which they are entitled pursuant to Section 2.6(c), in each case, without any interest thereon. Any amounts remaining unclaimed by holders of shares of Company Common Stock immediately prior to such time as such amounts would otherwise escheat to or become the property of any governmental entity shall, to the extent permitted by applicable law, become the property of Parent free and clear of any Liens, claims or interest of any Person previously entitled thereto.

(g) No Liability. Neither Parent nor the Surviving Entity shall be liable to any holder of shares of Company Common Stock for any such shares of Parent Common Stock (or dividends or distributions with respect thereto) or cash from the Exchange Fund delivered to a public official pursuant to any abandoned property, escheat or similar Law.

(h) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such Person of a bond, in such reasonable amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent shall pay in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable in respect of the shares of Company Common Stock represented by such Certificate, any cash in lieu of fractional Parent Common Stock to which the holders thereof are entitled pursuant to Section 2.6(e) and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 2.6(c), in each case, without any interest thereon.

(i) Withholding. Each of Parent, the Surviving Entity and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Company Common Stock such amounts as Parent, the Surviving Entity or the Exchange Agent is required to deduct and withhold under the Code or any provision of state, local, or foreign Tax Law, with respect to the making of such payment. To the extent that amounts are so withheld by Parent, the Surviving Entity or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Company Common Stock in respect of whom such deduction and withholding was made by Parent, the Surviving Entity or the Exchange Agent, as the case may be.

(j) Affiliate Shares. Notwithstanding anything herein to the contrary, Certificates surrendered for exchange by any “affiliate” of the Company (as determined pursuant to Section 5.16) shall not be exchanged until Parent has received a written agreement from such Person as provided in Section 5.16.

(k) Book Entry. All shares of Parent Common Stock to be issued in the Mergers shall be issued in book entry form, without physical certificates.

2.7 Stock Transfer Books. At the close of business on the date on which the Merger I Effective Time occurs, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of shares of Company Common Stock theretofore outstanding on the records of the Company. From and after the close of business on the date on which the Merger I Effective Time occurs, any Certificates presented to the Exchange Agent, Parent or the Surviving Entity for any reason shall be converted into the Merger Consideration payable in respect of the shares of Company Common Stock represented by such Certificates, any cash in lieu of fractional Parent Common Stock to which the holders thereof are entitled pursuant to Section 2.6(e) and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 2.6(c), in each case, without any interest thereon.

(a) The Company has furnished to Parent a reserve report prepared by Netherland, Sewell and Associates, Inc. containing estimates of the oil and gas reserves that are owned by the Company and its Subsidiaries as of December 31, 2005 (the “2005 Company Reserve Report”), and an internal reserve report prepared by the Company containing estimates of its oil and gas reserves that are owned by the Company and its Subsidiaries as of September 30, 2006 (the “Interim Company Reserve Report,” and together with the 2005 Company Reserve Report, the “Company Reserve Report”).

With respect to any Oil and Gas Interests of the Company and its Subsidiaries that are not operated by the Company or any of its Subsidiaries, the Company makes the representations and warranties set forth in this Section 3.6 only to its knowledge without having made specific inquiry of the operators with respect hereto.

statements (including the related notes, where applicable) has been, and the financial statements to be filed by Parent with the SEC after the date of this Agreement will be, prepared in accordance with GAAP consistently applied during the periods involved, except as indicated in the notes thereto or, in the case of unaudited statements, as permitted by Rule 10-01 of Regulation S-X of the SEC. The books and records of Parent and its Subsidiaries have been, and are being, maintained in accordance with GAAP and any other applicable legal and accounting requirements and reflect only actual transactions. KPMG was an independent public accounting firm for Parent as disclosed in the Parent SEC Documents. Ernst & Young LLP is an independent public accounting firm with respect to Parent and has not resigned (or indicated that it declines to stand for re-appointment after completion of the current audit) or been dismissed as independent public accountants of Parent.

(c) Since January 1, 2000, (A) the exercise price of each Parent Stock Option has been no less than the Fair Market Value (as defined under the terms of the respective Parent stock plan under which such Parent Stock Option was granted) of a share of Parent Common Stock as determined on the date of grant of such Parent Stock Option, and (B) all grants of Parent Stock Options were validly issued and properly approved by the Parent Board (or a duly authorized committee or subcommittee thereof) in material compliance with applicable Law and recorded in Parent’s financial statements referred to in Section 4.5(b) in accordance with GAAP, and no such grants involved any “back dating,” “forward dating” or similar practices with respect to the effective date of grant.

4.6 Oil and Gas Reserves.

(a) Parent has furnished to the Company reserve reports prepared by Parent and audited by DeGolyer and MacNaughton and Ryder Scott Company containing estimates of the oil and gas reserves that are owned by Parent or any of its Subsidiaries as of December 31, 2005 (collectively, the “2005 Parent Reserve Report”) and another such report audited by DeGolyer and MacNaughton containing estimates of the Alaskan oil and gas reserves that are owned by Parent or any of its Subsidiaries as of June 30, 2006 (the “2006 Parent Reserve Report”) and the internal reserve report prepared by Parent containing estimates of certain oil and gas reserves that are owned by Parent or any of its Subsidiaries as of September 30, 2006 (collectively, the “Interim Parent Reserve Report,” and together with the 2005 Parent Reserve Report and the 2006 Parent Reserve Report, the “Parent Reserve Report”). The factual, non-interpretive data relating to the Oil and Gas Interests of Parent and its Subsidiaries on which the Parent Reserve Report was based for purposes of estimating the oil and gas reserves set forth therein, to the knowledge of Parent, was accurate in all material respects at the time such information was provided to the reserve engineers for the 2005 Parent Reserve Report and the 2006 Reserve Report and utilized by the Parent for the Interim Parent Reserve Report. The 2005 Parent Reserve Report and the 2006 Parent Reserve Report conform to the guidelines with respect thereto of the SEC. Except for changes (including changes in Hydrocarbon commodity prices) generally affecting the oil and gas industry and normal depletion by production, there has been no change in respect of the matters addressed in the Parent Reserve Report that would reasonably be expected to have a Material Adverse Effect on Parent. Since January 1, 2003 all of Parent’s and its Subsidiaries’ wells have been drilled and (if completed) completed, operated and produced in compliance in all respects with applicable oil and gas leases and applicable Laws, except where any noncompliance would not have a Material Adverse Effect on Parent.

To Parent’s knowledge, neither Parent nor any of its Subsidiaries is in violation of any Applicable Law or contract requiring Parent of such Subsidiary to plug and abandon any well because the well is not currently capable of producing in commercial quantities or for any other reasons. With respect to any Oil and Gas Interests of Parent and its Subsidiaries that are not operated by Parent or any of its Subsidiaries, Parent makes the representations and warranties set forth in this Section 4.6 only to its knowledge without having made special inquiry of the operators with respect hereto.

(b) Set forth in Section 4.6(b) of the Parent Disclosure Letter is a list of all material Oil and Gas Interests that were included in the Interim Parent Reserve Report that have been disposed of prior to the date hereof.

4.7 Absence of Certain Changes.

(b) Since September 30, 2006 to the date of this Agreement and except as set forth in Section 4.7(b) of the Parent Disclosure Letter, neither Parent nor any of its Subsidiaries has (i) declared, set aside or paid any dividend or other distribution (whether in cash, stock or property) with respect to any of Parent’s capital stock, (ii) effected or authorized any split, combination or reclassification of any of Parent’s capital stock or any issuance thereof or issued any other securities in respect of, in lieu of or in substitution for shares of Parent’s capital stock, except for issuances of Parent Common Stock (1) upon the exercise of Parent Stock Options, in each case in accordance with their terms at the time of exercise or (2) in connection with recruitment activities in the ordinary course of business consistent with past practice, (iii) changed in any material respect, or has knowledge of any reason that would have required or would require changing in any material respect, any accounting methods (or underlying assumptions), principles or practices of Parent or its Subsidiaries, including any material reserving, renewal or residual method, practice or policy, except as required by GAAP or by applicable Law, (iv) made any material Tax election or settled or compromised any material income Tax liability, (v) made any material change in the policies and procedures of Parent or its Subsidiaries in connection with trading activities, (vi) sold, leased exchanged, transferred or otherwise disposed of any material Parent Asset other than in the ordinary course of business consistent with past practices, (vii) revalued, or has knowledge of any reason that would have required or would require revaluing, any of the Parent Assets in any material respect, including writing down the value of any of Parent Assets or writing off notes or accounts receivable other than in the ordinary course of business consistent with past practices, (viii) except as required to comply with applicable Law, adopted or amended any new or existing Parent Benefit Plan, or (ix) made any agreement or commitment (contingent or otherwise) to do any of the foregoing.

4.8 Absence of Undisclosed Liabilities. Since December 31, 2005 and except as set forth in Section 4.8 of the Parent Disclosure Letter, none of Parent or Merger Sub, nor any of Parent’s other Subsidiaries, has incurred any liabilities or obligations (accrued, contingent or

otherwise), except for (i) liabilities incurred in the ordinary course of business that individually or in the aggregate have not had, and would not be reasonably likely to have or result in, a Material Adverse Effect on Parent, (ii) liabilities in respect of Litigation (which are the subject of Section 4.11(a)), and (iii) liabilities under Environmental Laws (which are the subject of Section 4.15). None of Parent or Merger Sub, nor any of Parent’s other Subsidiaries, is in default in respect of the terms and conditions of any indebtedness or other agreement which individually or in the aggregate has had, or would be reasonably likely to have or result in, a Material Adverse Effect on Parent.

(b) None of the information supplied or to be supplied by the Parent for inclusion or incorporation by reference in any document provided to a lender or potential lender in connection with the Financing (or any amendment or supplement to such a document), will, at the date on which the Financing is consummated, contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading.

Each contract, arrangement, commitment or understanding of the type described in this Section 4.14(a), whether or not included as an exhibit to Parent SEC Documents, is referred to herein as a “Parent Material Contract,” and for purposes of Section 5.1(r) and the bringdown of Section 4.14(b) pursuant to Section 6.2(a), “Parent Material Contract” shall include as of date entered into any such contract, arrangement, commitment or understanding that is entered into after the date of this Agreement. Parent has previously made available to the Company true, complete and correct copies of each Parent Material Contract that is not included as an exhibit to Parent SEC Documents.

(a) the business of Parent and its Subsidiaries shall be conducted only in the ordinary course substantially consistent with past practice; provided, however, that neither the foregoing nor anything to the contrary in this Agreement shall be deemed to prohibit Parent or any of its Subsidiaries from engaging in any acquisition or divestiture transaction that does not constitute an Acquisition Proposal for Parent and would not reasonably be expected to have a Material Adverse Effect on Parent or materially impair or delay the consummation of the transactions contemplated by this Agreement;

(b) Parent shall not, nor shall it permit any of its Subsidiaries to, take any action that would reasonably be expected to (i) result in any of the conditions to the Merger set forth in Article VI not being satisfied, (ii) result in a Material Adverse Effect on Parent or (iii) materially impair or delay consummation of the Mergers or the other transaction contemplated hereby;

Any violation of the foregoing restrictions by any of the Company’s Subsidiaries or by any Representative of the Company or any of its Subsidiaries, whether or not such Representative is so authorized and whether or not such Representative is purporting to act on behalf of the Company or any of its Subsidiaries or otherwise, shall be deemed to be a breach of this Agreement by the Company. Notwithstanding anything to the contrary in this Agreement, the Company and the Company Board may take any actions described in clause (ii) of this Section 5.3(a) with respect to a third party at any time prior to obtaining the Company Required Vote if, prior to such vote, (x) the Company receives a bona fide written Acquisition Proposal with respect to the Company from such third party (and such Acquisition Proposal was not initiated, solicited, knowingly encouraged or facilitated by the Company or any of its Subsidiaries or any of their respective Representatives after the date and in violation of this Agreement), (y) the Company Board determines in good faith by resolution duly adopted (after consultation with its financial advisors and outside legal counsel) that such proposal constitutes or is reasonably likely to result in a Superior Proposal from the third party that made the applicable Acquisition Proposal with respect to the Company, and (z) the Company Board determines in good faith by resolution duly adopted (after consultation with its financial advisors and outside legal counsel) that the third party making such Acquisition Proposal has the financial and legal capacity to consummate such Acquisition Proposal, provided that the Company shall not deliver any information to such third party without entering into an

Acceptable Confidentiality Agreement; no actions taken in accordance with this sentence shall constitute a violation of clause (i) of this Section 5.3(a). Nothing contained in this Section 5.3 shall prohibit the Company or the Company Board from taking and disclosing to the Company’s stockholders a position with respect to an Acquisition Proposal with respect to the Company pursuant to Rule 14d-9 and 14e-2(a) promulgated under the Exchange Act or from making any similar disclosure, in either case to the extent required by applicable Law.

(b) The Company agrees that in addition to the obligations of the Company set forth in paragraph (a) of this Section 5.3, as promptly as practicable after receipt thereof (but in no event more than 24 hours after the Company’s receipt thereof), the Company shall advise Parent in writing of any request for information from a Person that has made, or the Company reasonably believes may be contemplating, an Acquisition Proposal with respect to the Company or any Acquisition Proposal with respect to the Company received from any Person, or any inquiry made or discussions or negotiations sought to be initiated or continued with respect to any Acquisition Proposal with respect to the Company, and the material terms and conditions of such request, Acquisition Proposal, inquiry, discussions or negotiations, and the Company shall promptly provide to Parent copies of any written materials received by the Company in connection with any of the foregoing and any correspondence related thereto, and the identity of the Person or group making any such request, Acquisition Proposal or inquiry or with whom any discussions or negotiations are taking place. The Company agrees that it shall provide to Parent any non-public information concerning the Company or its Subsidiaries provided to any other Person or group in connection with any Acquisition Proposal with respect to the Company which was not previously provided to Parent as promptly as practicable after it provides such information to such other Person. The Company shall keep Parent fully informed of the status of any Acquisition Proposals with respect to the Company (including the identity of the parties and price involved and any material changes to any terms and conditions thereof).

(c) Neither (i) the Company Board nor any committee thereof shall directly or indirectly (A) withdraw (or amend or modify in a manner adverse to Parent or Merger Sub), or publicly propose to withdraw (or amend or modify in a manner adverse to Parent or Merger Sub), the approval, recommendation or declaration of advisability by the Company Board or any such committee thereof of this Agreement, the Mergers or the other transactions contemplated by this Agreement or (B) recommend, adopt or approve, or propose publicly to recommend, adopt or approve, any Acquisition Proposal with respect to the Company (any action described in this clause (i) being referred to as a “Company Adverse Recommendation Change”) nor (ii) shall the Company or any of its Subsidiaries execute or enter into, any agreement, including any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement or other similar agreement, arrangement or understanding, (A) constituting or related to, or that is intended to or could reasonably be expected to lead to, any Acquisition Proposal (other than an Acceptable Confidentiality Agreement permitted pursuant to Section 5.3(a)) (each an “Acquisition Agreement”) with respect to the Company or (B) requiring it to abandon, terminate or fail to consummate the Mergers or any other transaction contemplated by this Agreement. Notwithstanding anything to the contrary in this Agreement, at any time prior to obtaining the Company Required Vote, and subject to the Company’s compliance at all times with the provisions of this Section 5.3 and Section 5.6, the Company Board may make a Company Adverse Recommendation Change described in clause (A) of the definition thereof if the

Company Board (i) determines in good faith, after consultation with outside legal counsel, that the failure to make a Company Adverse Recommendation Change described in clause (A) of the definition thereof would be reasonably expected to be inconsistent with its fiduciary duties to the stockholders of the Company, and (ii) provides written notice to Parent (a “Company Notice of Change”) advising Parent that the Company Board is contemplating making such Company Adverse Recommendation Change and specifying the material facts and information constituting the basis for such contemplated determination; provided, however, that (x) the Company Board may not make such Company Adverse Recommendation Change until the fourth Business Day after receipt by Parent of the Company Notice of Change and (y) during such four Business Day period, at the request of Parent, the Company shall negotiate in good faith with respect to any changes or modifications to this Agreement which would allow the Company Board not to make such Company Adverse Recommendation Change consistent with its fiduciary duties.

(d) Parent agrees that, except as expressly contemplated by this Agreement, neither it nor any of its Subsidiaries shall, and Parent shall, and shall cause its Subsidiaries to, cause their respective Representatives not to (i) directly or indirectly initiate, solicit or knowingly encourage or facilitate (including by way of furnishing non-public information) any inquiries regarding or the making or submission of any proposal that constitutes, or may reasonably be expected to lead to, an Acquisition Proposal with respect to Parent, (ii) participate or engage in discussions or negotiations with, or disclose any non-public information relating to Parent or any of its Subsidiaries or afford access to the properties, books or records of Parent or any of its Subsidiaries to any Person that has made an Acquisition Proposal with respect to Parent or to any Person that Parent, any of its Subsidiaries or any of their respective Representatives knows or has reason to believe is contemplating making an Acquisition Proposal with respect to Parent, or (iii) accept an Acquisition Proposal with respect to Parent or enter into any agreement, including any letter of intent or agreement in principle (other than an Acceptable Confidentiality Agreement in circumstances contemplated in the penultimate sentence of this Section 5.3(d)), (x) providing for, constituting or relating to an Acquisition Proposal with respect to Parent or (y) that would require, or would have the effect of causing, Parent to abandon, terminate or fail to consummate the Mergers or the other transactions contemplated by this Agreement. Any violation of the foregoing restrictions by any of Parent’s Subsidiaries or by any Representative of Parent or any of its Subsidiaries, whether or not such Representative is so authorized and whether or not such Representative is purporting to act on behalf of the Parent or any of its Subsidiaries or otherwise, shall be deemed to be a breach of this Agreement by Parent. Notwithstanding anything to the contrary in this Agreement, Parent and Parent Board may take any actions described in clause (ii) of this Section 5.3(d) with respect to a third party at any time prior to obtaining the Parent Required Vote if, prior to such approval, (x) Parent receives a bona fide written Acquisition Proposal with respect to Parent from such third party (and such Acquisition Proposal was not initiated, solicited, knowingly encouraged or facilitated by Parent or any of its Subsidiaries or any of their respective Representatives after the date and in violation of this Agreement) and (y) the Parent Board determines in good faith by resolution duly adopted (after consultation with its financial advisors and outside legal counsel) that such proposal constitutes or is reasonably likely to result in a Superior Proposal from the third party that made the applicable Acquisition Proposal with respect to Parent, and (z) the Parent Board determines in good faith by resolution duly adopted (after consultation with its financial advisors and outside legal counsel) that the third party making such Acquisition Proposal has the financial and legal capacity to consummate such Acquisition Proposal, provided that Parent shall not deliver any information to such third

party without entering into an Acceptable Confidentiality Agreement; no actions taken in accordance with this sentence shall constitute a violation of clause (i) of this Section 5.3(d). Nothing contained in this Section 5.3 shall prohibit Parent or the Parent Board from taking and disclosing to Parent’s shareholders a position with respect to an Acquisition Proposal with respect to Parent pursuant to Rule 14d-9 and 14e-2(a) promulgated under the Exchange Act or from making any similar disclosure, in either case to the extent required by applicable Law.

(e) Parent agrees that in addition to the obligations of Parent set forth in paragraph (d) of this Section 5.3, as promptly as practicable after receipt thereof (but in no event more than 24 hours after Parent’s receipt thereof), Parent shall advise the Company in writing of any request for information from a Person that has made, or Parent reasonably believes may be contemplating, an Acquisition Proposal with respect to Parent or any Acquisition Proposal with respect to Parent received from any Person, or any inquiry made or discussions or negotiations sought to be initiated or continued with respect to any Acquisition Proposal with respect to Parent, and the material terms and conditions of such request, Acquisition Proposal, inquiry, discussions or negotiations, and Parent shall promptly provide to the Company copies of any written materials received by Parent in connection with any of the foregoing and any correspondence related thereto, and the identity of the Person or group making any such request, Acquisition Proposal or inquiry or with whom any discussions or negotiations are taking place. Parent agrees that it shall provide to the Company any non-public information concerning Parent or its Subsidiaries provided to any other Person or group in connection with any Acquisition Proposal with respect to Parent which was not previously provided to the Company as promptly as practicable after it provides such information to such other Person. Parent shall keep the Company fully informed of the status of any Acquisition Proposals with respect to Parent (including the identity of the parties and price involved and any material changes to any terms and conditions thereof).

(f) Neither (i) the Parent Board nor any committee thereof shall directly or indirectly (A) withdraw (or amend or modify in a manner adverse to the Company), or publicly propose to withdraw (or amend or modify in a manner adverse to the Company), the approval, recommendation or declaration of advisability by the Parent Board or any such committee thereof of this Agreement, the Mergers, the Parent Proposal or the other transactions contemplated by this Agreement or (B) recommend, adopt or approve, or propose publicly to recommend, adopt or approve, any Acquisition Proposal with respect to Parent (any action described in this clause (i) being referred to as a “Parent Adverse Recommendation Change”), nor (ii) shall Parent or any of its Subsidiaries execute or enter into, (A) any Acquisition Agreement with respect to Parent (other than an Acceptable Confidentiality Agreement permitted pursuant to Section 5.3(d)) or (B) any agreement, including any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement or other similar agreement, arrangement or understanding, requiring it to abandon, terminate or fail to consummate the Mergers or any other transaction contemplated by this Agreement. Notwithstanding anything to the contrary in this Agreement, at any time prior to obtaining the Parent Required Vote, and subject to Parent’s compliance at all times with the provisions of this Section 5.3 and Section 5.6, the Parent Board may make a Parent Adverse Recommendation Change described in clause (A) of the definition thereof if the Parent Board (i) determines in good faith, after consultation with its outside legal counsel, that the failure to make a Parent

Adverse Recommendation Change described in clause (A) of the definition thereof would be reasonably expected to be inconsistent with its fiduciary duties to the shareholders of Parent, and (ii) provides written notice to the Company (a “Parent Notice of Change”) advising the Company that the Parent Board is contemplating making such Parent Adverse Recommendation Change and specifying the material facts and information constituting the basis for such contemplated determination; provided, however, that (x) the Parent Board may not make such Parent Adverse Recommendation Change until the fourth Business Day after receipt by the Company of the Parent Notice of Change and (y) during such four Business Day period, at the request of the Company, Parent shall negotiate in good faith with respect to any changes or modifications to this Agreement which would allow the Parent Board not to make such Parent Adverse Recommendation Change consistent with its fiduciary duties.

(g) For purposes of this Agreement, “Acquisition Proposal” shall mean, with respect to the Company or Parent, as the case may be, any proposal, whether or not in writing (other than by Parent or any of its Subsidiaries with respect to the Company, or by the Company or any of its Subsidiaries, with respect to Parent), for the (i) direct or indirect acquisition or purchase of a business or assets that generates or constitutes 20% or more of the net revenues, net income or the assets (based on the book or fair market value thereof) of such party and its Subsidiaries, taken as a whole (including capital stock of or ownership interest in any Subsidiary), (ii) direct or indirect acquisition or purchase of 20% or more of any class of equity securities or capital stock of such party or any of its Subsidiaries whose business generates or constitutes 20% or more of the net revenues, net income or assets (based on the book or fair market value thereof) of such party and its Subsidiaries, taken as a whole, or (iii) merger, consolidation, restructuring, transfer of assets or other business combination, sale of shares of capital stock, tender offer, exchange offer, recapitalization, stock repurchase program or other similar transaction that if consummated would result in any Person or Persons beneficially owning 20% or more of any class of equity securities of such party or any of its Subsidiaries whose business generates or constitutes 20% or more of the net revenues, net income or assets (based on the book or fair market value thereof) of such party and its Subsidiaries, taken as a whole, other than the transactions contemplated by this Agreement or as set forth in Section 5.3(g) of the Company Disclosure Letter or the Parent Disclosure Letter. The term “Superior Proposal” shall mean, with respect to the Company or Parent, as the case may be, any bona fide written Acquisition Proposal with respect to such party that was not initiated, solicited, facilitated or knowingly encouraged by such party or any of its Subsidiaries or any of their respective Representatives in violation of this Agreement, made by a third party to acquire, directly or indirectly, pursuant to a tender offer, exchange offer, merger, share, exchange, asset purchase or other business combination, (A) 50% or more of the assets of such party and its Subsidiaries, taken as a whole or (B) 50% or more of the equity securities of such party, in each case on terms which the majority of the Board of Directors of such party determines (after consultation with its financial advisors and outside legal counsel) in good faith by resolution duly adopted (A) would result in a transaction that, if consummated, is more favorable to the stockholders of such party (in their capacity as stockholders) from a financial point of view, than the Mergers, taking into account all the terms and conditions of such proposal and this Agreement (including any changes to the terms of this Agreement offered by the other party in response to such Superior Proposal or otherwise pursuant to this Section 5.3), and (B) is reasonably capable of being completed on the terms proposed, taking into account all financial, regulatory, legal and other aspects of such proposal; provided, however, that no proposal shall be

deemed to be a Superior Proposal if any financing required to consummate the proposal is not committed (unless it is reasonable to conclude that the proposed acquiror has adequate financial resources to consummate the transaction).

(h) For the avoidance of doubt, any factually accurate and complete public statement by a party hereto that does nothing more than disclose the receipt of an Acquisition Proposal with respect to such party that was not initiated, solicited or knowingly facilitated or encouraged after the date of this Agreement by such party or any of its Subsidiaries or any of their respective Representatives, and the terms thereof, shall not be deemed to be a recommendation of such Acquisition Proposal or the withdrawal, amendment or modification of the recommendation of the Board of Directors (or any committee thereof) in favor of this Agreement and the transactions contemplated hereby.

(i) Immediately after the execution and delivery of this Agreement, each of the Company and Parent shall, and shall cause its Subsidiaries and their respective Representatives to, cease and terminate any existing activities, discussions or negotiations with any Person conducted heretofore with respect to any possible Acquisition Proposal with respect to the Company and Parent, respectively. Each of the Company and Parent agrees that it shall (i) take the necessary steps to promptly inform its Representatives involved in the transactions contemplated by this Agreement of the obligations undertaken in this Section 5.3 and (ii) request each Person who has heretofore executed a confidentiality agreement within the last 12 months in connection with such Person’s consideration of any Acquisition Proposal with respect to it, or any similar transaction to return or destroy (which destruction shall be certified in writing by an executive officer of such Person) all confidential information heretofore furnished to such Person by or on its behalf.

5.4 Access to Information and Properties.

(a) Upon reasonable notice and subject to applicable Laws relating to the exchange of information, each of the Company and Parent shall, and shall cause each of its Subsidiaries to, afford to the authorized representatives of the other party, including officers, employees, accountants, counsel, financial advisors and other representatives of the other party, reasonable access, including the right to conduct Phase I environmental site assessments but specifically excluding soil or groundwater sampling or effluent sampling or testing or subsurface testing of any kind unless consented to in writing by the Company or Parent, as applicable (which consent shall not be unreasonably withheld, delayed or conditioned), during normal business hours during the period prior to the Merger I Effective Time, to all of its properties, offices, contracts, books, commitments, records, data and books and personnel and, during such period, it shall, and shall cause each of its Subsidiaries to, make available to the other parties all information concerning its business, properties and personnel as the other parties may reasonably request. No party or any of its Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would violate or prejudice the rights of its customers, jeopardize any attorney-client privilege or contravene any Law or binding agreement entered into prior to the date of this Agreement. The Company and Parent will make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.

(b) Parent and the Company will hold any information obtained or contemplated under Section 5.4(a) above in accordance with the provisions of the confidentiality agreement between Lehman Brothers Inc. and Parent, dated as September 14, 2006, and the confidentiality agreement between the Company and Parent, dated as of November 13, 2006 (collectively, the “Confidentiality Agreements”).

(c) No investigation by Parent or the Company or their respective Representatives made pursuant to this Section 5.4 shall affect the representations, warranties, covenants or agreements of the other set forth in this Agreement.

5.5 Further Action; Commercially Reasonable Efforts.

(a) Upon the terms and subject to the conditions herein provided, each of the parties hereto agrees to use its commercially reasonable efforts to take, or cause to be taken, all action and to do, or cause to be done, all things necessary, proper or advisable under applicable Laws or otherwise to consummate and make effective the transactions contemplated by this Agreement, including using commercially reasonable efforts to satisfy the conditions precedent to the obligations of any of the parties hereto, to obtain all necessary authorizations, consents and approvals, and to effect all necessary registrations and filings. Each of the parties hereto will furnish to the other parties such necessary information and reasonable assistance as such other parties may reasonably request in connection with the foregoing and, subject to applicable Laws and any applicable privilege relating to the exchange of information, will provide the other parties with copies of all filings made by such party with any Governmental Entity (except for filings available publicly on the SEC’s EDGAR system) or any other information supplied by such party to a Governmental Entity in connection with this Agreement and the transactions contemplated hereby; provided that neither party is obligated to share any document submitted to a Governmental Entity that reflects the negotiations between the parties or the valuation of some or all of any party’s business.

(b) Each of Parent, Merger Sub and the Company shall use their respective commercially reasonable efforts and shall cooperate with the other parties to resolve such objections, if any, as may be asserted with respect to the transactions contemplated hereby under the laws, rules, guidelines or regulations of any Governmental Entity. Without limiting the foregoing, the Company and Parent shall, as soon as practicable, file Notification and Report Forms under the HSR Act with the Federal Trade Commission (the “FTC”) and the Antitrust Division of the Department of Justice (the “Antitrust Division”) and shall use commercially reasonable efforts to respond as promptly as practicable to all inquiries received from the FTC, the Antitrust Division for additional information or documentation.

(c) Parent shall have the Financing or other funding sufficient to consummate the Mergers and the other transactions contemplated hereby. Parent shall, and shall cause its Subsidiaries and its and their respective officers and employees to use all reasonable efforts in connection with the arrangement of the Financing and any other financing that Parent, in its reasonable discretion, deems necessary to fund the transactions contemplated hereby. In the event Parent arranges for alternative Financing, it shall promptly provide to the Company the commitment letter and any similar documentation with respect thereto. The Commitment Letter shall be in full force and effect, or if alternative Financing has been arranged, the commitment

letter with respect to such alternative Financing shall be in full force and effect, at all times until the Effective Time, or the transactions contemplated by such Commitment Letter or such alternative Financing commitment letter shall have been consummated.

(d) The Company shall, and shall cause its Subsidiaries and its and their respective officers, employees, and shall use its reasonable best efforts to cause its advisors and accountants to, provide reasonable and customary cooperation with Parent and its affiliates in connection with the arrangement of the Financing and any other financing that Parent, in its reasonable discretion, deems necessary to fund the transactions contemplated hereby, including participation in meetings, due diligence sessions, road shows, rating agency presentations, the preparation of offering memoranda, private placement memoranda, prospectuses, rating agency presentations, other marketing material and similar documents, obtaining comfort letters from the Company’s accountants (which comfort letters shall be customary in form, scope and substance), and obtaining legal opinions from the Company’s outside counsel (which legal opinions shall be customary in form, scope and substance), as may be reasonably requested by Parent. In conjunction with the obtaining of any such financing, the Company agrees, at the reasonable request of Parent, to call for prepayment or redemption, or to prepay or redeem, or to attempt to renegotiate the terms of, any then existing indebtedness for borrowed money of the Company; provided, however, that the Company shall not be obligated to make or cause to become effective such prepayment or redemption or call for prepayment or redemption or renegotiated terms (nor shall the Company be required to incur any cost or liability in respect of any such prepayment or redemption or call therefor or renegotiation thereof) prior to the Merger I Effective Time.

(e) In case at any time after the Merger I Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement, the proper officers and/or directors of the Surviving Entity shall take or cause to be taken all such necessary action.

(f) Each of the parties hereto shall use commercially reasonable efforts to prevent the entry of, and to cause to be discharged or vacated, any order or injunction of a Governmental Entity precluding, restraining, enjoining or prohibiting consummation of the Mergers.

(g) Notwithstanding the foregoing provisions of this Section 5.5, neither Parent nor Merger Sub shall be required to accept, as a condition to obtaining any required approval or resolving any objection of any Governmental Entity, any requirement to divest or hold separate or in trust (or the imposition of any other condition or restriction with respect to) any assets or operations of Parent or Merger Sub or any of their respective affiliates or any of the respective businesses of the Company or any of its Subsidiaries, including the Company Assets. aftabalam

Each of the Company and Parent shall use its reasonable best efforts to have the S-4 declared effective under the Securities Act as promptly as practicable after such filling, and each of the Company and Parent shall as promptly as practicable thereafter mail the Proxy Statement to its stockholders.

(b) If at any time prior to the Merger I Effective Time, any event or circumstance relating to the Company, Parent, Merger Sub or any of their respective affiliates, or its or their respective officers or directors, should be discovered by the Company, Parent or Merger Sub that should be set forth in an amendment to the S-4 or a supplement to the Proxy Statement, the Company, Parent or Merger Sub shall promptly inform the other parties hereto thereof in writing. All documents that the Company or Parent is responsible for filing with the SEC in connection with the transactions contemplated herein will comply as to form in all material respects with applicable requirements of the Securities Act and the Exchange Act. The parties shall notify each other promptly of the time when the S-4 has become effective, of the issuance of any stop order or suspension of the qualification of the Parent Common Stock issuable in connection with the Mergers for offering or sale in any jurisdiction, or of the receipt of any comments from the SEC or the staff of the SEC and of any request by the SEC or the staff of the SEC for amendments or supplements to the Proxy Statement or the S-4 or for additional information and shall supply each other with copies of (i) all correspondence between it or any of its Representatives, on the one hand, and the SEC or the staff of the SEC, on the other hand, with respect to the Proxy Statement, the S-4 or the Mergers and (ii) all orders of the SEC relating to the S-4.

(c) The Company, acting through the Company Board, shall, in accordance with its certificate of incorporation and bylaws and with applicable Law, promptly and duly call, give notice of, convene and hold, as soon as practicable following the date upon which the S-4 becomes effective for the purposes of voting upon the adoption of this Agreement and the approval of the consummation of the transactions contemplated by this Agreement, including the Mergers, a special meeting of its stockholders for the sole purpose of considering and taking action upon this Agreement (such meeting, including any postponement or adjournment thereof, the “Company Special Meeting”), and shall use its reasonable best efforts to hold the Company Special Meeting no later than 45 days after such date. Except as otherwise provided in Section 5.3(c), the Company, acting through the Company Board, shall (i) recommend adoption of this Agreement and include in the Proxy Statement such recommendation and (ii) use its reasonable best efforts to solicit and obtain such adoption. Notwithstanding any Company Adverse Recommendation Change or the commencement, public proposal, public disclosure or communication to the Company of any Acquisition Proposal with respect to the Company or any of its Subsidiaries, or any other fact or circumstance (except for termination of this Agreement pursuant to Section 7.1), this Agreement shall be submitted to the stockholders of the Company at the Company Special Meeting for the purpose of adopting this Agreement, with such

disclosures as shall be required by applicable Law. At any such Company Special Meeting following any such withdrawal, amendment or modification of the Company Board’s recommendation of this Agreement, the Company may submit this Agreement to its stockholders without a recommendation or with a negative recommendation (although the approval of this Agreement by the Company Board may not be rescinded or amended), in which event the Company Board may communicate the basis for its lack of a recommendation or negative recommendation to its stockholders in the Proxy Statement or an appropriate amendment or supplement thereto.

(d) Parent, acting through the Parent Board, shall, in accordance with its certificate of incorporation and bylaws and with applicable Law, promptly and duly call, give notice of, convene and hold, as soon as practicable following the date upon which the S-4 becomes effective for the purposes of voting upon the Parent Proposal and, if applicable, Plan Amendment a special meeting of its shareholders (such meeting, including any postponements or adjournments thereof, the “Parent Special Meeting”), and shall use its reasonable best efforts to hold the Parent Special Meeting no later than 45 days after such date. Except as otherwise provided in Section 5.3(d), Parent, acting through the Parent Board, shall (i) recommend approval of the Parent Proposal and, if applicable, Plan Amendment and include in the Proxy Statement such recommendation and (ii) use its reasonable best efforts to solicit and obtain such approval. Notwithstanding any Parent Adverse Recommendation Change or the commencement, public proposal, public disclosure or communication to Parent of any Acquisition Proposal with respect to Parent or any of its Subsidiaries, or any other fact or circumstance (except for termination of this Agreement pursuant to Section 7.1), the Parent Proposal and, if applicable, Plan Amendment shall be submitted to the shareholders of Parent at the Parent Special Meeting for the purpose of approval of the Parent Proposal and, if applicable, Plan Amendment, with such disclosures as shall be required by applicable Law. At any such Parent Special Meeting following any such withdrawal, amendment or modification of the Parent Board’s recommendation of the Parent Proposal, Parent may submit the Parent Proposal and, if applicable, Plan Amendment to its shareholders without a recommendation or with a negative recommendation of the Parent Proposal (although the approval of the Parent Proposal by the Parent Board may not be rescinded or amended), in which event the Parent Board may communicate the basis for its lack of a recommendation or negative recommendation to its shareholders in the Proxy Statement or an appropriate amendment or supplement thereto.

(e) Promptly following the execution and delivery of this Agreement, Parent, as the owner of all of the outstanding shares of capital stock of Merger Sub, will adopt this Agreement and the transactions contemplated hereby in its capacity as sole stockholder of Merger Sub.

(f) The Parent shall use its best efforts to take all actions to consummate the Second Merger pursuant to Section 1.1(b) as a “short form” merger under Delaware Law.

5.7 Notification of Certain Matters. The Company shall give prompt notice to Parent of any fact, event or circumstance as to which the Company obtains knowledge that would be reasonably likely to result in a failure of a condition set forth in Sections 6.3(a) or 6.3(b). Parent and Merger Sub shall give prompt notice to the Company of any fact, event or circumstance as to which Parent or Merger Sub obtained knowledge that would be reasonably

likely to result in a failure of the representation set forth in Section 4.30 or a condition set forth in Sections 6.2(a) or 6.2(b).

5.8 Directors’ and Officers’ Insurance and Indemnification.

(a) Without limiting any rights that any such Person may have under any employment agreement or Company Benefit Plan of the Company, after the Merger I Effective Time, Parent and the Surviving Entity shall, jointly and severally, indemnify, defend and hold harmless the present and former officers and directors of the Company and any of its Subsidiaries as described in Section 5.8(a) of the Company Disclosure Letter in such capacities (“Indemnified Parties”) to the fullest extent permitted by Law, in each case against any losses, damages, fines, penalties, expenses (including attorneys’ fees and expenses) or liabilities resulting from any claim, liability, loss, damage, cost or expense, asserted against, or incurred by, an Indemnified Party that is based on the fact that such Indemnified Party is or was a director, officer, employee, fiduciary or agent of the Company or any of its Subsidiaries and arising out of actions or omissions or alleged actions or omissions in their capacity as a director, officer, employee, fiduciary or agent of the Company or any of its Subsidiaries occurring at or prior to the Merger I Effective Time (including in connection with this Agreement and the transactions and actions contemplated hereby). Parent and the Surviving Entity shall, jointly and severally, pay expenses in advance of the final disposition of any proceeding or threatened action, suit, proceeding, investigation or claim relating to any such acts or omissions or alleged acts or omissions (a “Proceeding”) to each Indemnified Party to the fullest extent permitted under applicable Law. Each Indemnified Party will be entitled to receive such advances from Parent or the Surviving Entity within ten Business Days of receipt by Parent or the Surviving Entity from the Indemnified Party of a request therefor; provided that any Person to whom expenses are advanced provides an undertaking, if and only to the extent required by law, to repay such advances if it is ultimately determined that such Person is not entitled to indemnification. Neither Parent nor the Surviving Entity shall settle, compromise or consent to the entry of any judgment in any Proceeding (and in which indemnification could be sought by such Indemnified Party hereunder), unless such settlement, compromise or consent includes an unconditional release of such Indemnified Party from all liability arising out of such Claim or such Indemnified Party otherwise consents. Parent and the Surviving Entity shall, and shall cause their Subsidiaries to, cooperate in the defense of any such matter. Parent and the Surviving Entity agree that all rights to exculpation, advancement of expenses and indemnification for acts or omissions occurring prior to the Merger I Effective Time now existing in favor of the current and former officers and directors of the Company as provided in the certificate of incorporation or bylaws of the Company or any Company Material Contract, employment agreement or Company Benefit Plan, in each case in effect as of the date hereof, shall survive the Mergers and shall continue in full force and effect in accordance with their terms and without amendment thereof.

(b) Prior to the Closing, the Company shall purchase (after obtaining the written approval of Parent, which approval shall not be unreasonably withheld, delayed or conditioned), and after the Merger I Effective Time the Surviving Entity shall maintain, and after Merger II Effective Time, Parent shall maintain or, if the Company has not already done so, purchase tail directors’ and officers’ liability insurance coverage, at no expense to the beneficiaries, with a claims period of six years from the Merger I Effective Time, with respect to

the directors and officers of the Company and its Subsidiaries who are currently covered by the Company’s existing directors’ and officers’ liability insurance with respect to claims arising from facts or events that occurred before the Merger I Effective Time, from an insurance carrier with the same or better credit rating as the Company’s current insurance carrier, in an amount and scope and on terms and conditions no less favorable to such directors and officers than those in effect on the date of this Agreement; provided, however, that the annual premium for such insurance shall not exceed 200% of the per annum rate of premium currently paid by the Company and its Subsidiaries for such insurance on the date of this Agreement. In the event that the annual premium for such insurance exceeds such maximum amount, Parent shall purchase as much coverage per policy year as reasonably obtainable for such maximum amount.

(c) This covenant is intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Parties and their respective heirs and legal representatives. The indemnification provided for herein shall not be deemed exclusive of any other rights to which an Indemnified Party is entitled, whether pursuant to law, contract or otherwise.

(d) In the event that the Surviving Entity or Parent, or any of their respective successors or assigns, (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Surviving Entity or Parent, as the case may be, shall succeed to the obligations set forth in this Section 5.8.

5.9 Publicity. None of the Company, Parent or Merger Sub, nor any of their respective affiliates, shall issue or cause the publication of any press release or other announcement with respect to the Mergers, this Agreement or the other transactions contemplated by this Agreement without the prior consultation of the other party, except as may be required by Law or by any listing agreement with, or regulation of, any securities exchange or regulatory authority if all reasonable best efforts have been made to consult with the other party. In addition, the Company shall to the extent reasonably practicable consult with Parent regarding the form and content of any public disclosure of any material developments or matters involving the Company, including earnings releases, reasonably in advance of publication or release.

5.10 Stock Exchange Listing. Parent shall use its reasonable best efforts to cause the Parent Common Stock to be issued in connection with the Mergers to be listed on the NYSE, subject to official notice of issuance as of the Merger I Effective Time.

5.11 Employee Benefits.

(a) For the one year period beginning at the Merger I Effective Time, Parent (including, without limitation, the Surviving Entity) shall cause the Company Employees who continue employment with Parent or its Subsidiaries to receive (during the period of such employment) (i) at least the same annual base salary or annual wages, as applicable, as such Company Employees were receiving immediately prior to the Merger I Effective Time and (ii) employee benefits on a basis substantially similar to those provided to similarly situated employees of Parent; provided, however, that Parent may, in its discretion, continue eligibility for coverage of some or all of the Company Employees under one or more Company Benefit

Plans in lieu of providing such Company Employees with eligibility for coverage under a corresponding plan of Parent. To the extent required in any employment agreement between the Company and any Company Employee, as of the Merger I Effective Time Parent and the Surviving Entity assume and agree to perform such agreement.

(b) To the extent service is relevant for purposes of eligibility, participation or vesting (but not the accrual of benefits under any defined benefit pension plan) under any employee benefit plan, program or arrangement established or maintained by Parent in which Company Employees may participate, such Company Employees shall be credited for service accrued as of the Merger I Effective Time with the Company and its Subsidiaries to the extent such service was credited under a similar plan, program or arrangement of the Company. Parent agrees that the Company Employees who continue employment with Parent shall be eligible for a bonus with respect to the full calendar year in which the Merger I Effective Time occurs on a basis substantially similar to that provided to similarly situated employees of Parent; provided, however, that if any such Company Employee commenced employment with the Company after January 1, 2007, then, subject to the terms of the applicable bonus plan, such Company Employee shall be eligible for a prorated bonus based on the period of his or her employment.

(c) To the extent Company Employees and their dependents enroll in any health plan sponsored by Parent, Parent shall waive any preexisting condition limitation applicable to such Company Employees to the extent that the employee’s or dependent’s condition would not have operated as a preexisting condition under the group health plan maintained by the Company. In addition, Parent shall cause such health plans (i) to waive all waiting periods otherwise applicable to Company Employees and their dependents, other than waiting periods that are in effect with respect to such individuals as of the Merger I Effective Time to the extent not satisfied under the corresponding benefit plans of the Company, and (ii) to provide each Company Employee and his or her dependents with corresponding credit for any co-payments and deductibles paid by them under the corresponding benefit plans of Company during the portion of the respective plan year prior to the Merger I Effective Time.

(d) With respect to any Company Employees who become employed by Parent after the Merger I Effective Time, Parent will permit such Company Employees to schedule and take vacation days that have accrued prior to the Merger I Effective Time with pay through December 31, 2007, and Parent shall give service credit for purposes of determining post Merger I Effective Time vacation, sick leave and any other paid time off entitlements that Parent provides to its employees generally.

(e) Prior to the Merger I Effective Time, the Company shall amend (i) the Company’s Change of Control Plan to provide that the duties of the plan administrator under such plan shall be performed by the Company or by one or more individuals designated from time to time by the Company (rather than the individual who is the Company’s Vice President – Chief Accounting Officer immediately prior to the Mergers), (ii) the Company’s Supplemental Executive Retirement Plan to eliminate the provisions of section 4.2 of such plan (relating to the appointment of an independent plan administrator), (iii) each other Company Benefit Plan and related trust agreement to the extent necessary to eliminate any restriction or limitation on the Company’s ability to appoint the administrator of such Company Benefit Plan or the trustee of any related trust and (iv) the Company’s 401(k) Plan and Trust and its 2005 Executive Deferred

Compensation Plan to provide for the full vesting of all account balances thereunder at the Merger I Effective Time with respect to participants who are employed by the Company immediately prior to the Merger I Effective Time. Each such amendment shall be in a form agreed to by Parent.

(f) In addition to the cash-out or cancellation of certain Company Options pursuant to Section 2.5, Parent shall on the Date of Grant (as hereinafter defined) grant a stock option under the Parent Stock Incentive Plan (or a comparable new incentive plan) to each Company Employee who (i) has remained continuously employed by Parent and its Subsidiaries from the Merger I Effective Time to the Date of Grant and (ii) held immediately prior to the Merger I Effective Time a Company Option that had an exercise price per share at such time equal to or greater than $54.18 (which Company Options previously have been disclosed to Parent), which option shall be in addition to and not be considered in lieu of or as satisfaction of Section 5.11(a). The stock option granted to each such Company Employee (A) shall cover a number of shares of Parent Common Stock equal to the number of shares of Company Common Stock subject to the Company Option described in clause (ii) of the immediately preceding sentence and with respect to which such Company Option was not exercised prior to the Merger I Effective Time (subject to adjustment as provided in the Parent Stock Incentive Plan), (B) shall have a purchase price per share of Parent Common Stock equal to the Fair Market Value (as such term is defined in the Parent Stock Incentive Plan) of a share of Parent Common Stock as of the Date of Grant (subject to adjustment as provided in the Parent Stock Incentive Plan), (C) shall not constitute an incentive stock option (within the meaning of section 422 of the Code), and (D) shall be subject to such other terms and conditions as are set forth in Parent’s standard form of stock option agreement which shall be used to evidence such grant (including terms and conditions relating to the term of the stock option, the vesting of the stock option and the exercise rights of the holder following a termination of employment). For purposes of this Section 5.11(f), the term “Date of Grant” means a Business Day selected by Parent in its sole discretion that is on or before the fifth Business Day following the date on which the Merger I Effective Time occurs. Nothing in this Section 5.11(f) nor any other provision herein shall give any employee of the Company or its Subsidiaries the right to be retained in the employ of Parent, the Surviving Entity or any Subsidiary of Parent, it being understood that none of Parent, the Surviving Entity or any Subsidiary of Parent shall have any obligation to continue employing any employee of the Company or its Subsidiaries for any length of time.

(g) The Company and Parent shall cooperate with each other in all reasonable respects relating to any actions to be taken pursuant to this Section 5.11. The Company shall allow Parent reasonable opportunities to meet with employees of the Company from the date hereof to the Merger I Effective Time in order to discuss and answer questions regarding employment and benefits.

(h) Nothing in this Agreement shall constitute an amendment to, or be construed as amending, any benefit plan, program or agreement sponsored, maintained or contributed to by Parent or any Subsidiary of Parent. No Company Employee nor any other Person (other than the parties to this Agreement) is intended to be a beneficiary of the provisions of this Section 5.11. Nothing in this Agreement (including Section 5.11(f)) shall require or be construed or interpreted as requiring Parent or any of its Subsidiaries to continue the employment of any Company Employee after the Merger I Effective Time.

For purposes of this Section 5.11, a “Company Employee” shall mean an individual who is employed by the Company or its Subsidiaries prior to the Merger I Effective Time and who thereafter remains or becomes an employee of Parent or a Subsidiary of Parent (including the Surviving Entity).

5.12 Rights Agreement. The Company Board shall take such action as is necessary to terminate the Company Rights Agreement and the Company Rights immediately prior to the Merger I Effective Time and to render the Company Rights inapplicable to the Merger and the other transactions contemplated by this Agreement.

5.13 Certain Tax Matters.

(a) This Agreement is intended to constitute a “plan of reorganization” within the meaning of Treasury Regulation Section 1.368-2(g).

(b) Parent and the Company shall each use its reasonable best efforts to cause the Mergers to qualify as a “reorganization” within the meaning of Section 368(a) of the Code and to obtain the Tax opinions set forth in Sections 6.2(d) and 6.3(d).

(c) Officers of Parent, Merger Sub and the Company shall execute and deliver to Akin Gump Strauss Hauer & Feld LLP, tax counsel for the Company, and Vinson & Elkins L.L.P., tax counsel for Parent, certificates substantially in the form agreed to by the parties and such firms at such time or times as may reasonably be requested by such firms, including contemporaneously with the execution of this Agreement, at the time the S-4 is declared effective by the SEC and the Merger I Effective Time, in connection with such tax counsel’s respective delivery of opinions pursuant to Sections 6.2(d) and 6.3(d) hereof. Each of Parent, Merger Sub and the Company shall use its reasonable best efforts not to take or cause to be taken any action that would cause to be untrue (or fail to take or cause not to be taken any action which would cause to be untrue) any of the certifications and representations included in the certificates described in this Section 5.13(c).

(d) The Company and Parent shall cooperate in the preparation, execution and filing of all Returns, questionnaires, applications or other documents regarding any real property transfer or gains, sales, use, transfer, value added, stock transfer and stamp taxes, and transfer, recording, registration and other fees and similar Taxes which become payable in connection with the Mergers that are required or permitted to be filed on or before the Merger I Effective Time. Each of Merger Sub and the Company shall pay, without deduction from any amount payable to holders of Company Common Stock and without reimbursement from the other party, any such Taxes or fees imposed on it by any Governmental Entity, which becomes payable in connection with the Mergers.

(e) Neither Parent nor Company will take (or fail to take) (and following the Mergers, Parent will cause the Company not to take or fail to take) any action which action (or failure to act) would reasonably be expected to cause the Mergers to fail to qualify as a reorganization within the meaning of Section 368(a) of the Code. With respect to the Mergers, Parent will (and following the Mergers will cause the Company to) file all required information with its Returns and maintain all records required for Tax purposes.

(f) Between the date hereof and the Closing Date, the Company agrees to (i) prepare all Returns, other than income tax Returns, for any periods ending prior to the Closing Date and which are required to be filed within 15 days following such date (taking extensions to file into account) using tax accounting methods and principles consistent with those used for preceding tax periods, unless a change is required by applicable Law or regulation, and (ii) prepare and submit to Parent income tax Returns, including quarterly income tax estimates, where such Returns would be required to be filed prior to 30 days following the Closing Date (taking extensions to file into account). The Company shall make such income tax Returns available to the Parent for review prior to filing with the relevant Governmental Entity and shall not refuse any reasonable request by the Parent with respect to such Returns. Such Returns shall be prepared and filed, and all related taxes paid, on or prior to the Closing Date.

5.14 Indenture Matters. In the event that Parent elects to obtain a consent from the holders of outstanding notes under the Company Indenture to an amendment to Article V of the Company Indenture that would permit a wholly owned Subsidiary of Parent in the form of a limited liability company to merge with the Company and to be the surviving entity in such merger, which amendment shall be in a form reasonably satisfactory to the Company, (a) the Company shall use commercially reasonable efforts to assist Parent in obtaining such consent, (b) upon obtaining such consent, the parties shall cooperate in implementing an amendment to the Merger Agreement to reflect an amendment to the structure of the Mergers such that a wholly owned Subsidiary of Parent in the form of a limited liability company would merge with the Company and be the surviving entity in such merger and (c) Parent shall bear all expenses of Parent and the Company related to such actions referred to in this Section 5.14.

5.15 Section 16 Matters. Prior to the Closing Date, Parent and the Company, and their respective Boards of Directors, shall use their reasonable best efforts to take all actions to cause any dispositions of Company Common Stock (including derivative securities with respect to Company Common Stock) or acquisitions of Parent Common Stock (including derivative securities with respect to Parent Common Stock) resulting from the transactions contemplated hereby by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act to be exempt from Section 16(b) of the Exchange Act under Rule 16b-3 promulgated under the Exchange Act in accordance with the terms and conditions set forth in that certain No-Action Letter, dated January 12, 1999, issued by the SEC to Skadden, Arps, Slate, Meagher & Flom LLP.

5.16 Affiliates Letter. Prior to the date of the Company Special Meeting, the Company shall deliver to Parent a list of names and addresses of those Persons who are, in the opinion of the Company, as of the time of the Company Special Meeting, “affiliates” of the Company within the meaning of Rule 145 under the Securities Act. The Company shall provide to Parent such information and documents as Parent shall reasonably request for purposes of reviewing such list. There shall be added to such list the names and addresses of any other Person subsequently identified by either Parent or the Company as a Person who may be deemed to be such an affiliate of the Company; provided, however, that no such Person identified by Parent shall be added to the list of affiliates of the Company if Parent shall receive from the Company, on or before the date of the Company Special Meeting, an opinion of counsel reasonably satisfactory to Parent to the effect that such Person is not such an affiliate. The Company shall exercise its commercially reasonable efforts to deliver or cause to be delivered to

Parent, prior to the date of the Company Special Meeting, from each affiliate of the Company identified in the foregoing list (as the same may be supplemented as aforesaid), a letter dated as of the Closing Date substantially in the form attached as Exhibit A (the “Affiliates Letter”). Parent shall not be required to maintain the effectiveness of the S-4 or any other registration statement under the Securities Act for the purposes of resale by such affiliates of Parent Common Stock received pursuant to the Mergers and Parent may direct the Exchange Agent not to issue certificates representing Parent Common Stock received by any such affiliate until Parent has received from such Person an Affiliates Letter. Parent may issue certificates representing Parent Common Stock received by such affiliates bearing a customary legend regarding applicable Securities Act restrictions and the provisions of this Section 5.16.

(a) by the mutual consent of Parent and the Company in a written instrument;

(b) by either the Company or Parent upon written notice to the other, if:

Exhibit A

FORM OF RULE 145 AFFILIATES LETTER

, 2007

Forest Oil Corporation
707 17^th Street, Suite 3600
Denver, Colorado 80202

Ladies and Gentlemen:

Reference is made to the Agreement and Plan of Merger (the “Merger Agreement”) dated as of January 7, 2007, by and among Forest Oil Corporation, a New York corporation (“Parent”), MJCO Corporation, a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”), and The Houston Exploration Company, a Delaware corporation (the “Company”), pursuant to which (i) the Merger Sub will merge with and into the Company (the “First Merger”), with the Company surviving the First Merger and (ii) the Company will subsequently merge with and into Parent (the “Second Merger,” and together with the First Merger, the “Mergers”), and Parent will survive the Second Merger, in each case on the terms set forth in the Merger Agreement. All capitalized and undefined terms used herein shall have the meanings set forth in the Merger Agreement.

The undersigned understands that the undersigned may be deemed an “affiliate” of the Company for purposes of Rule 145 promulgated under the Securities Act of 1933, as amended (the “Act”). Execution of this letter should not be considered an admission by the undersigned that the undersigned is an “affiliate” of the Company for purposes of Rule 145 under the Act or a waiver of any rights that the undersigned may have to object to any claim that the undersigned is an affiliate on or after the date of this letter. The undersigned is delivering this letter pursuant to Section 5.16 of the Merger Agreement.

With respect to such securities of Parent as may be received by the undersigned pursuant to the Merger Agreement (the “Shares”), the undersigned represents to and agrees with Parent that:

A. The undersigned will not make any offer to sell or any sale, transfer or other disposition of all or any part of the Shares in violation of the Act or the rules and regulations thereunder, including Rule 145, and will hold the Shares subject to all applicable provisions of the Act and the rules and regulations thereunder.

B. The undersigned has been advised that the offering, sale and delivery of the Shares to the undersigned pursuant to the Merger Agreement will be registered under the Act on a Registration Statement on Form S-4. The undersigned has also been advised and agrees, however, that, since the undersigned may be deemed an “affiliate” of the Company, the undersigned may not offer, sell, pledge, hypothecate, transfer or otherwise dispose of any of the Shares except (i) in a transaction permitted by Rule 145 under the

A-1

Act, or (ii) pursuant to an effective registration statement under the Act or (iii) in a transaction that is not required to be registered under the Act.

C. The undersigned understands and agrees that neither Parent nor any of its current or future affiliates is under any obligation to register the sale, transfer or other disposition of any Shares by the undersigned or on the undersigned’s behalf under the Act or to take any other action necessary in order to make compliance with an exemption from such registration available.

D. The undersigned also understands that the Parent may give stop transfer instructions to its transfer agent with respect to the Shares and there will be placed on the certificates representing such Shares, or any substitutions thereof, a legend stating in substance:

“THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, APPLIES, AND MAY ONLY BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF (1) IN CONFORMITY WITH RULE 145, (2) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT, OR (3) IN ACCORDANCE WITH A WRITTEN OPINION OF COUNSEL IN FORM AND SUBSTANCE REASONABLY ACCEPTABLE TO THE PARENT THAT SUCH SALE, TRANSFER OR DISPOSAL IS EXEMPT FROM REGISTRATION UNDER THE ACT.”

The legend set forth above shall be removed by delivery of a substitute certificate without such legend, and the Parent shall so instruct its transfer agent, if (1) a registration statement registering the sale of the Shares has been declared effective under the Act or (2) the undersigned delivers to the Parent (a) satisfactory written evidence that the Shares have been sold in compliance with Rule 145 or (b) an opinion of counsel, in form and substance reasonably acceptable to the Parent, to the effect that the sale, transfer or disposal of the Shares by the holder thereof is no longer subject to Rule 145.

A-2

The undersigned acknowledges that (i) the undersigned has carefully read this letter and the Merger Agreement and discussed the requirements of such documents and other applicable limitations upon the undersigned’s ability to sell, transfer or otherwise dispose of the Shares, to the extent the undersigned felt necessary, with the undersigned’s counsel or counsel for the Company and (ii) the receipt by Parent of this letter is an inducement and a condition to Parent’s obligation to consummate the Mergers.
