Section 1.2 Closing. Unless this Agreement is terminated in accordance with Section 7.1, the closing of the Merger (the “Closing”) shall take place at the offices of Wachtell, Lipton, Rosen & Katz, 51 West 52nd Street, New York, New York at 10:00 a.m., local time, no later than the fourth business day after the satisfaction or waiver (to the extent permitted by applicable Law) of the conditions set forth in ARTICLE VI (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of such conditions), or at such other place, date and time as the Company and Parent may agree in writing. The date on which the Closing actually occurs is referred to as the “Closing Date.”

- 2 -

Section 1.3 Effective Time. On the Closing Date, the Company and Merger Sub shall file with the Secretary of State of the State of Delaware a certificate of merger (the “Certificate of Merger”), executed in accordance with, and containing such information as is required by, the relevant provisions of the DGCL in order to effect the Merger. The Merger shall become effective at such time as the Certificate of Merger has been filed with the Secretary of State of the State of Delaware or at such other, later date and time as is agreed between the parties and specified in the Certificate of Merger in accordance with the relevant provisions of the DGCL (such date and time is hereinafter referred to as the “Effective Time”).

Section 1.4 Effects of the Merger. The effects of the Merger shall be as provided in this Agreement and in the applicable provisions of the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all of the property, rights, privileges, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation, all as provided under the DGCL.

Section 1.5 Certificate of Incorporation and Bylaws of the Surviving Corporation.

(a) At the Effective Time, the certificate of incorporation of Merger Sub, as in effect immediately prior to the Effective Time, shall be the certificate of incorporation of the Surviving Corporation until thereafter amended in accordance with the provisions thereof and applicable Law.

(b) At the Effective Time, the bylaws of Merger Sub, as in effect immediately prior to the Effective Time, shall be the bylaws of the Surviving Corporation until thereafter amended in accordance with the provisions thereof and applicable Law.

Section 1.6 Directors. Subject to applicable Law, the directors of Merger Sub immediately prior to the Effective Time shall be the initial directors of the Surviving Corporation and shall hold office until their respective successors are duly elected and qualified, or their earlier death, resignation or removal.

Section 1.7 Officers. The officers of Merger Sub immediately prior to the Effective Time shall be the initial officers of the Surviving Corporation and shall hold office until their respective successors are duly elected and qualified, or their earlier death, resignation or removal.

ARTICLE II.

CONVERSION OF SHARES; EXCHANGE OF CERTIFICATES

Section 2.1 Conversion of Shares.

(a) At the Effective Time, by virtue of the Merger and without any action on the part of the Company, Parent or Merger Sub or the holder of any shares of Company Common Stock or shares of common stock of Merger Sub:

- 3 -

(i) Common Stock of Merger Sub. Each share of common stock, par value $0.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall, at the Effective Time, by virtue of the Merger and without any action on the part of Parent, be converted into one fully paid and nonassessable share of the common stock, par value $0.01 per share, of the Surviving Corporation.

(ii) Cancellation of Certain Stock. Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time that is owned or held in treasury by the Company and each share of Company Common Stock issued and outstanding immediately prior to the Effective Time that is owned by Parent or Merger Sub or any of their respective Subsidiaries (as defined herein) (including, for the avoidance of doubt, any shares acquired by Parent or any Subsidiary of Parent pursuant to the transactions contemplated by the Pennsylvania Merger Agreement) shall no longer be outstanding and shall automatically be cancelled and shall cease to exist (the “Cancelled Shares”), and no consideration shall be delivered in exchange therefor; provided, however, that any shares of Company Common Stock owned or held by any direct or indirect wholly owned Subsidiary of the Company shall be converted into the right to receive the Merger Consideration, as set forth below. For the avoidance of doubt, this Section 2.1(a)(ii) shall not apply to shares of Company Common Stock held in trust or otherwise set aside from shares held in the Company’s treasury pursuant to or in respect of a Company Benefit Plan.

(iii) Conversion of Company Common Stock. Subject to the other provisions of ARTICLE II, each share of Company Common Stock issued and outstanding immediately prior to the Effective Time, other than any Cancelled Shares or Dissenting Shares (as defined herein), shall be converted automatically into and shall thereafter represent the right to receive $14.75 in cash, without interest (the “Cash Consideration”) and (2) 1.15 Royalty Trust Units (the “Unit Consideration” and together with the Cash Consideration, the “Merger Consideration”).

All of the shares of Company Common Stock converted into the right to receive the Merger Consideration pursuant to this ARTICLE II shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time, and uncertificated shares of Company Common Stock represented by book-entry form (“Book-Entry Shares”) and each certificate that, immediately prior to the Effective Time, represented any such shares of Company Common Stock (each, a “Certificate”) shall thereafter represent only the right to receive the Merger Consideration and any cash in lieu of fractional Royalty Trust Units into which the shares of Company Common Stock represented by such Book-Entry Share or Certificate have been converted pursuant to this Section 2.1.

(b) Shares of Dissenting Stockholders. Notwithstanding anything in this Agreement to the contrary, any issued and outstanding shares of Company Common Stock held by a person (a “Dissenting Stockholder”) who has not voted in favor of, or consented to, the adoption of this Agreement and has complied with the provisions of the DGCL concerning the right of holders of shares of Company Common Stock to require appraisal of their shares (the “Appraisal Provisions”) of Company Common Stock (“Dissenting Shares”), to the extent the Appraisal Provisions are applicable, shall not be converted into the right to receive the Merger

- 4 -

Consideration, but shall become the right to receive such consideration as may be determined to be due to such Dissenting Stockholder pursuant to the procedures set forth in Section 262 of the DGCL. If such Dissenting Stockholder effectively withdraws its demand for appraisal or fails to perfect or otherwise loses its right of appraisal, in any case pursuant to the DGCL, each of such Dissenting Stockholder’s shares of Company Common Stock shall thereupon be treated as if they had been converted as of the Effective Time into the right to receive the Merger Consideration. The Company shall give Parent prompt notice of any demands for appraisal of shares of Company Common Stock received by the Company, withdrawals of such demands and any other instruments served pursuant to Section 262 of the DGCL and shall give Parent the opportunity to participate in all negotiations and proceedings with respect thereto. 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.

(c) Certain Adjustments. If, between the date of this Agreement and the Effective Time (and as permitted by ARTICLE V), the outstanding shares of Company Common Stock shall have been changed into a different number of shares or a different class of shares by reason of any stock dividend, subdivision, reorganization, reclassification, recapitalization, stock split, reverse stock split, combination or exchange of shares, or any similar event shall have occurred, then the Merger Consideration shall be equitably adjusted, without duplication, to proportionally reflect such change; provided that nothing in this Section 2.1(c) shall be construed to permit the Company to take any action with respect to its securities that is prohibited by the terms of this Agreement.

(d) Company Convertible Securities. The Company Convertible Securities issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding unless converted prior to the Effective Time, and shall be treated in accordance with the respective terms of their underlying agreements following the Effective Time; provided, however, that the Company Convertible Securities that are owned by Parent and its Subsidiaries immediately prior to the Effective Time shall be cancelled and cease to exist at the Effective Time, and no consideration shall be delivered in exchange therefor.

Section 2.2 Exchange Agent. Prior to the Effective Time, Parent shall appoint a bank or trust company that is reasonably acceptable to the Company to act as exchange agent (the “Exchange Agent”) for the payment of the Merger Consideration and shall enter into an agreement (the “Exchange Agent Agreement”) relating to the Exchange Agent’s responsibilities under this Agreement.

Section 2.3 Exchange of Certificates Representing Company Common Stock.

(a) Deposit of Merger Consideration. At or prior to the Effective Time, Parent shall make available to the Exchange Agent cash sufficient to pay the aggregate Cash Consideration (together with, to the extent then determinable, the aggregate amount payable in lieu of fractional Royalty Trust Units pursuant to Section 2.3(j)) for the payment to holders of Company Common Stock and shall deposit, or shall cause to be deposited, with the Exchange Agent evidence of Royalty Trust Units in book-entry form (and/or certificates representing such Royalty Trust Units, at Parent’s election) representing the number of Royalty Trust Units

- 5 -

sufficient to deliver the aggregate Unit Consideration (such cash and certificates, together with any dividends or distributions with respect thereto, the “Exchange Fund”).

(b) Exchange Procedures. As soon as reasonably practicable after the Effective Time and in any event within four (4) business days of the Closing Date, Parent shall cause the Exchange Agent to mail to each holder of record of shares of Company Common Stock whose shares of Company Common Stock were converted pursuant to Section 2.1(a)(iii) into the right to receive the Merger Consideration (A) 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 delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Parent and the Company may reasonably agree upon prior to the Effective Time) (the “Letter of Transmittal”) and (B) instructions for use in effecting the surrender of Certificates or Book-Entry Shares in exchange for the Merger Consideration.

(c) Surrender of Certificates or Book-Entry Shares. Upon surrender of Certificates or Book-Entry Shares to the Exchange Agent together with the Letter of Transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may customarily be required by the Exchange Agent, the holder of such Certificates or Book-Entry Shares shall be entitled to receive in exchange therefor the Merger Consideration and any cash in lieu of fractional Royalty Trust Units into which the shares represented by such Certificates or Book-Entry Shares have been converted pursuant to this Agreement. In the event of a transfer of ownership of shares of Company Common Stock that is not registered in the transfer or stock records of the Company, any cash to be paid upon, or Royalty Trust Units to be issued upon, due surrender of the Certificate or Book-Entry Share formerly representing such shares of Company Common Stock may be paid or issued, as the case may be, to such a transferee if such Certificate or Book-Entry Share is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer or other similar Taxes have been paid or are not applicable. No interest shall be paid or shall accrue on the cash payable upon surrender of any Certificate or Book-Entry Share. Until surrendered as contemplated by this Section 2.3, each Certificate and Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive, upon such surrender, the Merger Consideration and any cash in lieu of fractional Royalty Trust Units into which the shares represented by such Certificates or Book-Entry Shares have been converted pursuant to this Agreement.

(d) No Further Ownership Rights in Company Common Stock. From and after the Effective Time, (i) all holders of Certificates and Book-Entry Shares shall cease to have any rights as stockholders of Company other than the right to receive the Merger Consideration and any cash in lieu of fractional shares into which the shares represented by such Certificates or Book-Entry Shares have been converted pursuant to this Agreement upon the surrender of such Certificate or Book-Entry Share in accordance with Section 2.3(b), without interest, and (ii) the stock transfer books of the Company shall be closed with respect to all shares of Company Common Stock outstanding immediately prior to the Effective Time. From and after the Effective Time, the stock transfer books of the Company shall be closed, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of shares of Company Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificates or Book-Entry Shares formerly representing shares of

- 6 -

Company Common Stock are presented to the Surviving Corporation, Parent or the Exchange Agent for any reason, such Certificates or Book-Entry Shares shall be cancelled and exchanged as provided in this ARTICLE II, subject to applicable Law in the case of Dissenting Shares.

(e) Investment of Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Parent; provided, however, that no such investment or loss thereon shall affect the amounts payable to holders of Certificates or Book- Entry Shares pursuant to this ARTICLE II, and following any losses from any such investment, Parent shall promptly provide additional funds to the Exchange Agent for the benefit of the holders of shares of Company Common Stock at the Effective Time in the amount of such losses, which additional funds will be deemed to be part of the Exchange Fund. Any interest or other income resulting from such investments shall be paid to Parent, upon demand.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund (including any interest or other amounts received with respect thereto) that remains unclaimed by, or otherwise undistributed to, the holders of Certificates and Book-Entry Shares for one year after the Effective Time shall be delivered to Parent, upon demand, and any holder of Certificates or Book-Entry Shares who has not theretofore complied with this ARTICLE II shall thereafter look only to Parent or the Surviving Corporation (subject to abandoned property, escheat or other similar Laws), as general creditors thereof, for satisfaction of its claim for Merger Consideration and any cash in lieu of fractional Royalty Trust Units without any interest thereon.

(g) No Liability. None of Parent, the Company, Merger Sub or the Exchange Agent shall be liable to any person in respect of any portion of the Exchange Fund or the Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. Notwithstanding any other provision of this Agreement, any portion of the Merger Consideration or the cash to be paid in accordance with this ARTICLE II that remains undistributed to the holders of Certificates and Book-Entry Shares as of the second anniversary of the Effective Time (or immediately prior to such earlier date on which the Merger Consideration or such cash would otherwise escheat to or become the property of any Governmental Entity), shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation, free and clear of all claims or interest of any person previously entitled thereto.

(h) Withholding Rights. Each of the Surviving Corporation, Parent and the Exchange Agent (without duplication) shall be entitled to deduct and withhold from the consideration otherwise payable to any holder of a Certificate or Book-Entry Share pursuant to this Agreement such amounts as are required to be deducted and withheld with respect to the making of such payment under applicable Tax Law. Any amounts so deducted, withheld and paid over to the appropriate Taxing Authority shall be treated for all purposes of this Agreement as having been paid to the holder of the Certificate or Book-Entry Share in respect of which such deduction or withholding was made.

(i) 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 or the Exchange Agent, the posting by such

- 7 -

person of a bond in such amount as Parent or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Exchange Agent (or, if subsequent to the termination of the Exchange Fund and subject to Section 2.3(g), Parent) shall deliver, in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration and any cash in lieu of fractional Royalty Trust Units.

(j) Fractional Royalty Trust Units. No certificates or scrip representing fractional Royalty Trust Units shall be issued upon the conversion of any shares of Company Common Stock pursuant to Section 2.1. Notwithstanding any other provision of this Agreement, each holder of shares of Company Common Stock converted pursuant to the Merger who would otherwise have been entitled to receive a fraction of a Royalty Trust Unit (after taking into account all shares of Company Common Stock exchanged by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to such fractional amount multiplied by the average closing price of one Royalty Trust Unit on the stock exchange on which the Royalty Trust Units are listed (as reported in The Wall Street Journal or, if not reported therein, in another authoritative source mutually selected by Parent and the Company) for the first five trading days immediately following the date of the Effective Time.

Section 2.4 Equity-Based Awards.

(a) Each option to purchase Shares granted pursuant to a Company Stock Plan (each, a “Company Option”) that is outstanding immediately prior to the Effective Time shall, as of the Effective Time, be converted into an option (each, an “Adjusted Option”) to purchase, on the same terms and conditions as were applicable to such Company Option outstanding immediately prior to the Effective Time, the number of shares of Parent Common Stock, rounded down to the nearest whole share, determined by multiplying the number of Shares subject to the Company Option immediately prior to the Effective Time by the Equity Award Exchange Ratio, at an exercise price per share of Parent Common Stock, rounded up to the nearest whole cent, equal to the per share exercise price for the Shares otherwise purchasable pursuant to the Company Option outstanding immediately prior to the Effective Time divided by the Equity Award Exchange Ratio.

(b) Each award of restricted stock units in respect of Shares granted under a Company Stock Plan (each, a “Company RSU”) that is outstanding as of the Effective Time shall be converted as of the Effective Time into a restricted stock unit award (each, an “Adjusted RSU”) in respect of the number of shares of Parent Common Stock, rounded to the nearest whole share, determined by multiplying the number of Shares subject to the Company RSU outstanding immediately prior to the Effective Time by the Equity Award Exchange Ratio, with each Adjusted RSU to continue to be subject to the same terms and conditions as were applicable to the related Company RSU outstanding or payable immediately prior to the Effective Time.

(c) Each right of any kind (excluding Company Options and Company RSUs), contingent or accrued, to receive Shares or cash payments measured by the value of a number of Shares granted under a Company Deferred Compensation Plan (each, an “Other Stock-Based Award”) that are outstanding immediately prior to the Effective Time shall be deemed to be converted as of the Effective Time into the right to receive (or to be credited with) the number

- 8 -

of shares, or benefits measured by the value of the number of shares, of Parent Common Stock, rounded to the nearest whole share, equal to the product of (i) the number of Shares subject to the Other Stock-Based Award outstanding immediately before the Effective Time, and (ii) the Equity Award Exchange Ratio (each, an “Adjusted Other Stock-Based Award”), with each Adjusted Other Stock-Based Award to continue to be subject to the same terms and conditions as were applicable to the related Other Stock-Based Award outstanding immediately prior to the Effective Time.

(d) Prior to the Effective Time, the Company Board and/or the appropriate committee thereof shall adopt resolutions providing for the treatment of the Company Options, Company RSUs, and Other Stock-Based Awards (collectively, the “Company Stock Awards”) outstanding immediately prior to the Effective Time as contemplated by this Section 2.4. For the avoidance of doubt, in no event shall any holder of a Company Stock Award receive the Merger Consideration as consideration for such Company Stock Awards. As of the Effective Time, Parent shall file one or more appropriate registration statements (on Form S-3 or Form S-8, or any successor or other appropriate forms) with respect to Parent Common Stock underlying the Adjusted Options and in respect of the Adjusted RSUs and the Adjusted Other Stock-Based Awards pursuant to this Section 2.4.

(e) For the purposes of this Section 2.4:

(i) “Company Closing Price” shall mean the average, rounded to the nearest one hundredth of a cent, of the closing sales prices of shares of Company Common Stock on the NYSE as reported by The Wall Street Journal for the five trading days immediately preceding the date on which the Effective Time occurs.

(ii) “Company Deferred Compensation Plan” means the McMoRan Exploration Co. Supplemental Executive Capital Accumulation Program, excluding any Qualified Plans.

(iii) “Company Stock Plans” mean the Company 1998 Stock Option Plan, the Company Amended and Restated 2000 Stock Incentive Plan, the Company Amended and Restated 2001 Stock Incentive Plan, Company Amended and Restated 2003 Stock Incentive Plan, the Company Amended and Restated 2004 Director Compensation Plan, the Company Amended and Restated 2005 Stock Incentive Plan and the Company Amended and Restated 2008 Stock Incentive Plan.

(iv) “Equity Award Exchange Ratio” shall mean the Company Closing Price divided by the Parent Closing Price, rounded to the nearest one ten thousandth.

(v) “Parent Closing Price” shall mean the average, rounded to the nearest one hundredth of a cent, of the closing sales prices of shares 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 Effective Time occurs.

Section 2.5 Further Assurances. If at any time before or after the Effective Time, Parent or the Company reasonably believes or is advised that any further instruments, deeds, assignments or assurances are reasonably necessary or desirable to consummate the Merger or to

- 9 -

carry out the purposes and intent of this Agreement at or after the Effective Time, then Parent, Merger Sub, the Company and the Surviving Corporation and their respective officers and directors shall execute and deliver all such proper instruments, deeds, assignments or assurances and do all other things reasonably necessary or desirable to consummate the Merger and to carry out the purposes and intent of this Agreement.

ARTICLE III.

REPRESENTATIONS AND WARRANTIES OF THE COMPANY

Except as disclosed in the Company SEC Documents filed prior to the date hereof (including information set forth in any exhibit thereto but excluding any disclosures set forth in any risk factor section, any disclosure in any section relating to forward-looking statements or any other statements that are predictive or primarily cautionary in nature other than historical facts included therein) or in the disclosure schedule delivered by the Company to Parent immediately prior to the execution of this Agreement (the “Company Disclosure Schedule”) (each section of which qualifies the correspondingly numbered representation, warranty or covenant if specified therein and such other representations, warranties or covenants where its relevance as an exception to (or disclosure for purposes of) such other representation, warranty or covenant is reasonably apparent), the Company represents and warrants to Parent as follows:

Section 3.1 Qualification, Organization, Subsidiaries, etc.

(a) The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware and has all requisite corporate power and authority to own, lease and operate its properties and assets and to carry on its business as presently conducted, except where the failure to have such power and authority has not had and would not have, individually or in the aggregate, a Company Material Adverse Effect.

Notwithstanding the foregoing, the Company shall not be required to afford

- 39 -

such access if it would unreasonably disrupt the operations of the Company or any of its Subsidiaries, would cause a violation of any Contract to which the Company or any of its Subsidiaries is a party, would cause a risk of a loss of privilege to the Company or any of its Subsidiaries or would constitute a violation of any applicable Law.

- 40 -

confidentiality provision that does not, and would not be reasonably likely to, facilitate, encourage or relate in any way to a Company Takeover Proposal or a potential Company Takeover Proposal and (B) the Company shall, and shall cause its Subsidiaries to, use their respective reasonable best efforts to (1) enforce the confidentiality and standstill provisions of any such agreement, and (2) immediately take all steps within their power necessary to terminate any waiver that may have been heretofore granted, to any person other than Parent or any of Parent’s Affiliates, under any such provisions.

(b) Notwithstanding anything to the contrary contained in Section 5.3(a), if at any time from and after the date of this Agreement and prior to obtaining the Company Stockholder Approval, the Company, directly or indirectly receives a bona fide, unsolicited written Company Takeover Proposal from any person that did not result from the Company’s, its Affiliates’ or the Company’s or its Affiliates’ Representatives breach of Section 5.3 and if the Company Board, acting upon the recommendation of the Company Special Committee if then in existence or otherwise by a majority of its Independent Directors, determines in good faith, after consultation with its outside financial advisors and outside legal counsel, that such Company Takeover Proposal constitutes or would reasonably be expected to lead to a Company Superior Proposal, then the Company may, directly or indirectly, (A) furnish, pursuant to an Acceptable Confidentiality Agreement, information (including non-public information) with respect to the Company and its Subsidiaries, and afford access to the business, properties, assets, employees, officers, Contracts, books and records of the Company and its Subsidiaries, to the person who has made such Company Takeover Proposal and its Representatives and potential sources of financing; provided, that the Company shall substantially concurrently with the delivery to such person provide to Parent any non-public information concerning the Company or any of its Subsidiaries that is provided or made available to such person or its Representatives unless such non-public information has been previously provided or made available to Parent and (B) engage in or otherwise participate in discussions or negotiations with the person making such Company Takeover Proposal and its Representatives and potential sources of financing regarding such Company Takeover Proposal (including, as a part thereof, making counterproposals). “Acceptable Confidentiality Agreement” means any customary confidentiality agreement that contains provisions that are no less favorable to the Company than those applicable to Parent that are contained in the Confidentiality Agreement, provided that such confidentiality agreement (x) shall not prohibit compliance by the Company with any of the provisions of this Section 5.3 and (y) may contain a less restrictive standstill restriction.

The Company shall keep Parent reasonably informed, on a prompt basis, as to the status of (including changes to any material terms of, and any other material developments with respect to) such Company Takeover Proposal (including by promptly (and in no event later than 24 hours after receipt) providing to Parent copies of any additional or revised written proposals, indications of interest, and/or draft agreements relating to such Company Takeover Proposal). The Company agrees that it and its Subsidiaries will not enter into any agreement with any person subsequent to the date of this Agreement

- 41 -

which prohibits the Company from providing any information to Parent in accordance with this Section 5.3.

(d) Except as expressly permitted by this Section 5.3(d) and, with respect to (i)(A) and (i)(B) of this sentence only, Section 5.3(e), the Company Board shall not (i) (A) fail to include the Company Recommendation in the Proxy Statement, (B) change, qualify, withhold, withdraw or modify, or authorize or publicly propose to change, qualify, withhold, withdraw or modify, in a manner adverse to Parent, the Company Recommendation, (C) take any formal action or make any recommendation or public statement in connection with a tender offer or exchange offer (other than a recommendation against such offer or a customary “stop, look and listen” communication of the type contemplated by Rule 14d-9(f) under the Exchange Act) (it being understood that the Company Board may refrain from taking a position with respect to such a tender offer or exchange offer until the close of business as of the tenth business day after the commencement of such tender offer or exchange offer pursuant to Rule 14d-9(f) under the Exchange Act without such action being considered a Company Adverse Recommendation Change) or (D) adopt, approve or recommend, or publicly propose to adopt, approve or recommend to stockholders of the Company a Company Takeover Proposal (any action described in this clause (i) being referred to as a “Company Adverse Recommendation Change”), or (ii) authorize, cause or permit the Company or any of its Subsidiaries to enter into any letter of intent, agreement, commitment or agreement in principle with respect to any Company Takeover Proposal (other than an Acceptable Confidentiality Agreement entered into in accordance with Section 5.3(b)). Notwithstanding anything to the contrary set forth in this Agreement, prior to the time the Company Stockholder Approval is obtained, the Company Board may, acting upon the recommendation of the Company Special Committee if then in existence or otherwise by a majority of its Independent Directors make a Company Adverse Recommendation Change if, after receiving a bona fide, unsolicited Company Takeover Proposal that did not result from a breach of Section 5.3, the Company Board, acting upon the recommendation of the Company Special Committee if then in existence or otherwise by a majority of its Independent Directors, has determined in good faith, after consultation with its outside financial advisors and outside legal counsel, that (i) such Company Takeover Proposal constitutes a Company Superior Proposal and (ii) in light of such Company Takeover Proposal, the failure to take such action would be inconsistent with the Company Board’s fiduciary duties under applicable Law; provided, however, that, prior to making such Company Adverse Recommendation Change, (A) the Company has given Parent at least four (4) business days’ prior written notice of its intention to take such action (which notice shall specify the material terms and conditions of any such Company Superior Proposal) and has contemporaneously provided to Parent a copy of the Company Superior Proposal, a copy of any proposed transaction agreements with the person making such Company Superior Proposal and a copy of any financing commitments relating thereto (or, if not provided in writing to the Company, a written summary of the material terms thereof), (B) the Company has negotiated, and has caused its Representatives to negotiate, in good faith with Parent during such notice period, to the extent Parent wishes to negotiate, to enable Parent to propose revisions to the terms of this Agreement such that it would cause such Company Superior Proposal to no longer constitute a Company Superior Proposal, (C) following the end of such notice period, the Company Board, acting upon the recommendation of the Company Special Committee if then in existence or otherwise by a majority of its Independent Directors, shall have considered in good faith any revisions to the terms of this Agreement proposed in writing by Parent, and shall have determined, after consultation with its outside

financial advisors and outside legal counsel, that the Company Superior Proposal would nevertheless continue to constitute a Company Superior Proposal if the revisions proposed by Parent were to be given effect, and (D) in the event of any change to any of the financial terms (including the form, amount and timing of payment of consideration) or any other material terms of such Company Superior Proposal, the Company shall, in each case, have delivered to Parent an additional notice consistent with that described in clause (A) above of this proviso and a new notice period under clause (A) of this proviso shall commence (except that the four (4) business day period notice period referred to in clause (A) above of this proviso shall instead be equal to the longer of (1) two business days and (2) the period remaining under the notice period under clause (A) of this proviso immediately prior to the delivery of such additional notice under this clause (D)) during which time the Company shall be required to comply with the requirements of this Section 5.3(d) anew with respect to such additional notice, including clauses (A) through (D) above of this proviso; and provided, further, that the Company has complied in all material respect with its obligations under this Section 5.3.

(e) Other than in connection with a Company Superior Proposal (which shall be subject to Section 5.3(d) and shall not be subject to this Section 5.3(e)), nothing in this Agreement shall prohibit or restrict the Company Board from making a Company Adverse Recommendation Change in response to an Intervening Event if the Company Board, acting upon the recommendation of the Company Special Committee if then in existence or otherwise by a majority of its Independent Directors, has determined in good faith, after consultation with its outside legal counsel, that the failure of the Company Board to make a Company Adverse Recommendation Change would reasonably be likely to be inconsistent with the Company Board’s fiduciary duties under applicable Law; provided, however, that, prior to making such Company Adverse Recommendation Change, (A) the Company has given Parent at least four (4) business days prior written notice of its intention to take such action, which notice shall specify the reasons therefor, (B) the Company has negotiated, and has caused its Representatives to negotiate, in good faith with Parent during such notice period after giving any such notice, to the extent Parent wishes to negotiate, to enable Parent to propose revisions to the terms of this Agreement such that it would not permit the Company Board to make a Company Adverse Recommendation Change pursuant to this Section 5.3(e), (C) following the end of such notice period, the Company Board shall have considered in good faith any revisions to the terms of this Agreement proposed in writing by Parent, and shall have determined, after consultation with its outside financial advisors and outside legal counsel, that failure to make a Company Adverse Recommendation Change in response to such Intervening Event would be inconsistent with the Company Board’s fiduciary duties under applicable Law and (D) in the event of each and every change to the material facts and circumstances relating to such Intervening Event, the Company shall, in each case, have delivered to Parent an additional notice consistent with that described in clause (A) above of this proviso and a new notice period under clause (A) of this proviso shall commence (except that the four (4) business day notice period referred to in clause (A) above of this proviso shall instead be equal to the longer of (1) two business days and (2) the period remaining under the notice period under clause (A) of this proviso immediately prior to the delivery of such additional notice under this clause (D)), during which time the Company shall be required to comply with the requirements of this Section 5.3(e) anew with respect to such additional notice, including clauses (A) through (D) above of this proviso.

- 43 -

(f) Nothing contained in this Section 5.3 shall prohibit the Company or the Company Board from taking and disclosing to the stockholders of the Company a position contemplated by Rule 14e-2(a) or Rule 14d-9 promulgated under the Exchange Act or from making any “stop, look and listen” communication or any other similar disclosure to the stockholders of the Company pursuant to Rule 14d-9(f) under the Exchange Act if, in the determination in good faith of the Company Board, acting upon the recommendation of the Company Special Committee if then in existence or otherwise by a majority of its Independent Directors, after consultation with outside counsel, the failure so to disclose would reasonably be likely to be inconsistent with the fiduciary duties under applicable Law or obligations under applicable federal securities Law of the Company Board; provided, that any such position or disclosure (other than any “stop, look and listen” communication that includes a reaffirmation of the Company Recommendation) shall be deemed to be a Company Adverse Recommendation Change unless the Company Board expressly and concurrently reaffirms the Company Recommendation.

Section 5.4 Filings; Other Actions.

(a) As promptly as reasonably practicable following the date of this Agreement, the Company shall prepare and file with the SEC the preliminary Proxy Statement, Parent shall, and shall cause the Trust to, prepare and file with the SEC the Form S-4 and the Company and Parent shall jointly prepare and file the Schedule 13E-3 with the SEC, and the Company and Parent shall cooperate with each other in connection with the preparation of the foregoing. Parent shall reasonably cooperate with the Company in the preparation of the Proxy Statement and the Schedule 13E-3, including by providing the Company with any information regarding Parent or Merger Sub that is reasonably required to be included in the Proxy Statement or the Schedule 13E-3. The Company shall reasonably cooperate with Parent and the Trust in the preparation of the Form S-4, including by providing Parent and the Trust with any information regarding the Company or its properties or assets that is reasonably requested by Parent and required to be included in the Form S-4. The Company shall use its reasonable best efforts to respond to any comments of the SEC or its staff, to clear the preliminary Proxy Statement and the Schedule 13E-3 with the SEC as promptly as practicable after filing and to cause the Proxy Statement and Schedule 13E-3 to be mailed to the Company’s stockholders as promptly as practicable after responding to all such comments to the satisfaction of the SEC (or as otherwise directed by Parent with respect to coordinating with the mailing of the Form S-4). Parent and the Trust shall use their reasonable best efforts to respond to any comments of the SEC or its staff, to have the Form S-4 declared effective by the SEC as promptly as practicable after filing, and to cause the Form S-4 to be mailed to the Company’s stockholders as promptly as practicable after it is declared effective. Each of the Company and Parent will advise the other party, promptly after it receives notice thereof, of any request by the SEC or its staff for amendments or supplements to the Proxy Statement, the Schedule 13E-3 or the Form S-4, as applicable, or comments thereon or responses thereto or requests by the SEC or its staff for additional information. The Company will promptly provide Parent with copies of all correspondence between the Company (or its Representatives) and the SEC (or its staff) regarding the Proxy Statement, the Schedule 13E-3 or the Merger. No filing of, or amendment or supplement to, or correspondence to the SEC or its staff with respect to, the Proxy Statement or the Schedule 13E-3 will be made by the Company, without providing Parent and Merger Sub a reasonable opportunity to review and comment thereon (and the Company shall give reasonable

- 44 -

consideration to all reasonable comments suggested by Parent, Merger Sub or their counsel). If at any time prior to the Company Stockholders’ Meeting there shall occur any event that is required to be set forth in an amendment or supplement to the Proxy Statement or the Schedule 13E-3, the Company shall as promptly as reasonably practicable prepare and mail to its stockholders such an amendment or supplement.

(b) As promptly as reasonably practicable following the clearance of the Proxy Statement and the Schedule 13E-3 by the SEC and the declaration of effectiveness of the Form S-4, the Company shall take all action necessary in accordance with applicable Laws and the Company Organizational Documents to duly give notice of, convene and hold a meeting of its stockholders (including any postponement or adjournment thereof) for the purpose of obtaining the Company Stockholder Approval (the “Company Stockholders’ Meeting”). Notwithstanding anything to the contrary contained in this Agreement, the Company shall not adjourn or postpone the Company Stockholders’ Meeting without Parent’s consent; provided that without Parent’s consent, the Company may adjourn or postpone the Company Stockholders Meeting after consultation with Parent (i) to the extent necessary to ensure that any required supplement or amendment to the Proxy Statement, Form S-4 or Schedule 13E-3 is provided to the stockholders of the Company within a reasonable amount of time in advance of the Company Stockholders’ Meeting or (ii) if as of the time for which the Company Stockholders’ Meeting is originally scheduled (as set forth in the Proxy Statement) there are insufficient shares of Company Common Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the Company Stockholders’ Meeting or to solicit additional proxies and votes in favor of adoption of this Agreement if sufficient votes to constitute the Company Stockholder Approval have not been obtained. Subject to making a Company Adverse Recommendation Change, the Company Board shall recommend the adoption of this Agreement and shall take all lawful action to solicit such adoption of this Agreement. In the event that subsequent to the date hereof, the Company Board determines to make a Company Adverse Recommendation Change, the Company shall nevertheless submit this Agreement to the holders of the Company Common Stock for adoption at the Company Stockholders’ Meeting and take all other action necessary or advisable to solicit the vote or consent of its stockholders required by the rules of the NYSE or applicable law, and shall not submit to the vote of its stockholders any Company Takeover Proposal other than the Merger unless this Agreement shall have been terminated in accordance with its terms prior to such meeting.

(c) At the Company Stockholders’ Meeting or any postponement or adjournment thereof, Parent and Merger Sub shall vote, or cause to be voted, all of the shares of Company Common Stock then beneficially owned by either of them or any of their Subsidiaries and controlled affiliates in favor of the adoption of this Agreement.

(d) As promptly as reasonably practicable following the date of this Agreement, Parent will cause the Trust to prepare and file with the SEC a shelf registration statement on any appropriate form under the Securities Act (the “Shelf Registration Statement”) relating to the transfer of Royalty Trust Units to holders of Company Convertible Securities upon conversion of such holders’ Company Convertible Securities. Parent shall reasonably cooperate with the Trust in the preparation of the Shelf Registration Statement, including by providing the Trust with any information regarding Parent, the Company or their respective properties or assets that is reasonably requested by Parent and required to be included in the Shelf Registration

- 45 -

Statement. Parent and the Trust shall use their reasonable best efforts to respond to any comments of the SEC or its staff, to have the Shelf Registration Statement declared effective by the SEC as promptly as practicable after filing but in no event later than the Effective Time, and to cause the Shelf Registration Statement to remain continuously effective until the earlier of (i) the conversion, exchange, repurchase or redemption of all Company Convertible Securities or (ii) the maturity of each series of Company Convertible Securities.

Section 5.5 Employee Matters.

(a) Effective as of the Effective Time and for a period of one year thereafter, Parent shall provide, or shall cause the Surviving Corporation to provide, to employees of the Company or its Subsidiaries who continue to be employed by Parent or the Surviving Corporation or any of their respective Subsidiaries following the Effective Time (the “Company Employees”) for so long as the applicable Company Employee remains employed by Parent or the Surviving Corporation, compensation and benefits that are substantially comparable in the aggregate to the compensation and benefits paid and provided to similarly situated employees of Parent and its Subsidiaries (other than the Company and its Subsidiaries); provided, that for purposes of the foregoing sentence the Company Benefit Plans provided to employees of the Company as of immediately prior to the Effective Time shall remain in place and be deemed to be substantially comparable, on an aggregate basis, to those provided to similarly situated employees of Parent and its Subsidiaries for purposes of this sentence, it being understood that the Company Employees may commence participation in Parent’s benefit plans on different dates following the Effective Time with respect to different benefit plans.

(b) Following the Closing Date, Parent shall, or shall cause the Surviving Corporation to, cause any employee benefit plans sponsored or maintained by Parent or the Surviving Corporation or their Subsidiaries in which the Company Employees are eligible to participate following the Closing Date (collectively, the “Post-Closing Plans”) to recognize the service of each Company Employee with the Company and its Subsidiaries and all of their respective predecessor entities prior to the Closing Date for purposes of eligibility, vesting and benefit accrual rates or contribution rates under such Post-Closing Plans, in each case, to the same extent such service was recognized immediately prior to the Effective Time under a comparable Company Benefit Plan in which such Company Employee was eligible to participate immediately prior to the Effective Time; provided that such recognition of service shall not (i) apply for benefit accrual purposes of any defined benefit retirement plan or plan that provides retiree welfare benefits, (ii) operate to duplicate any benefits of a Company Employee with respect to the same period of service, (iii) apply for purposes of any plan, program or arrangement (x) under which similarly-situated employees of Parent and its Subsidiaries do not receive credit for prior service or (y) that is grandfathered or frozen, either with respect to level of benefits or participation. With respect to any Post-Closing Plan that provides medical, dental or vision insurance benefits, for the plan year in which such Company Employee is first eligible to participate, Parent shall use reasonable best efforts to (A) cause any pre-existing condition limitations or eligibility waiting periods under such plan to be waived with respect to such Company Employee to the extent such limitation would have been waived or satisfied under the Company Benefit Plan in which such Company Employee participated immediately prior to the Effective Time, and (B) credit each Company Employee for an amount equal to any medical, dental or vision expenses incurred by such Company Employee in the year that includes the

- 46 -

Closing Date (or, if later, the year in which such Covered Employee is first eligible to participate in such Post-Closing Plan) for purposes of any applicable deductible and annual out-of-pocket expense requirements under any such Post-Closing Plan to the extent such expenses would have been credited under the Company Benefit Plan in which such Company Employee participated immediately prior to the Effective Time, subject to the applicable information being provided to Parent. Such credited expenses shall also count toward any annual or lifetime limits, treatment or visit limits or similar limitations that apply under the terms of the applicable plan.

(c) Notwithstanding anything contained in this Agreement to the contrary, following the Effective Time, while employed by Parent or the Surviving Corporation, the Company Employees whose employment is governed by a Collective Bargaining Agreement shall be provided compensation and benefits pursuant to the terms of the applicable Collective Bargaining Agreement as in effect from time to time.

(d) If requested by Parent in writing delivered to the Company not less than ten (10) business days before the Closing Date, the Board of Directors of the Company (or the appropriate committee thereof) shall adopt resolutions and take such corporate action as is necessary to terminate, subject to the consummation of the transactions contemplated by this Agreement, and effective as of immediately prior to the Effective Time, the McMoRan Exploration Co. Employee Capital Accumulation Program (the “Company 401(k) Plan”). Following the Effective Time, the assets of the Company 401(k) Plan shall be distributed to the participants, and Parent shall permit the Company Employees who are then actively employed to make rollover contributions of “eligible rollover distributions” (within the meaning of Section 401(a)(31) of the Code) to Parent’s 401(k) plan. Individual account balances shall be valued as of the date of transfer, and the transfer shall be in cash, except that outstanding loan balances shall be transferred in the form of notes or other documentation evidencing such loans.

(e) From and after the Effective Time, Parent shall, or shall cause the Surviving Corporation to, honor all accrued and vested benefits under the Company Benefit Plans in accordance with their terms as in effect immediately before the Effective Time and applicable Law as such agreements and arrangements may be modified or terminated in accordance with their terms from time to time.

(f) Nothing in this Agreement shall confer upon any Company Employee or other service provider any right to continue in the employ or service of Parent, the Surviving Corporation or any affiliate of Parent, or shall interfere with or restrict in any way the rights of Parent, the Surviving Corporation or any of their affiliates, which rights are hereby expressly reserved, to discharge or terminate the services of any Company Employee at any time for any reason whatsoever, with or without cause. In no event shall the terms of this Agreement be deemed to (i) establish, amend, or modify any Company Benefit Plan or any “employee benefit plan” as defined in Section 3(3) of ERISA, or any other benefit plan, program, agreement or arrangement maintained or sponsored by Parent, Surviving Corporation, the Company or any of their Subsidiaries (including, after the Closing Date, Company and its Subsidiaries) or affiliates; or (ii) alter or limit the ability of Parent, the Surviving Corporation or any of their Subsidiaries (including, after the Closing Date, Company and its Subsidiaries) or affiliates to amend, modify or terminate any Company Benefit Plan, employment agreement or any other benefit or employment plan, program, agreement or arrangement after the Closing Date. Notwithstanding

- 47 -

any provision in this Agreement to the contrary, nothing in this Section 5.5 shall create any third party beneficiary rights in any Company Employee or current or former service provider of the Company or its affiliates (or any beneficiaries or dependents thereof).

Section 5.6 Regulatory Approvals; Efforts.

(a) Prior to the Closing, Parent, Merger Sub and the Company shall use their respective reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, all things necessary, proper or advisable under any applicable Laws to consummate and make effective the Merger including (i) the preparation and filing of all forms, registrations and notices required to be filed to consummate the Merger, (ii) the satisfaction of the conditions to consummating the Merger, (iii) taking all reasonable actions necessary to obtain (and cooperating with each other in obtaining) any consent, authorization, Order or approval of, or any exemption by, any third party, including any Governmental Entity (which actions shall include furnishing all information and documentary material required under the HSR Act) required to be obtained or made by Parent, Merger Sub, the Company or any of their respective Subsidiaries in connection with the Merger or the taking of any action contemplated by this Agreement, and (iv) the execution and delivery of any additional instruments necessary to consummate the Merger and to fully carry out the purposes of this Agreement. Additionally, each of Parent, Merger Sub and the Company shall use reasonable best efforts to fulfill all conditions precedent to the Merger and shall not take any action after the date of this Agreement that would reasonably be expected to materially delay the obtaining of, or result in not obtaining, any permission, approval or consent from any such Governmental Entity necessary to be obtained prior to Closing. To the extent that transfers of any permits issued by any Governmental Entity are required as a result of the execution of this Agreement or the consummation of the Merger, the parties hereto shall use reasonable best efforts to effect such transfers.

(b) Parent and the Company shall each keep the other apprised of the status of matters relating to the completion of the Merger and work cooperatively in connection with obtaining all required consents, authorizations, Orders or approvals of, or any exemptions by, any Governmental Entity undertaken pursuant to the provisions of this Section 5.6. In that regard, prior to the Closing, each party shall promptly consult with the other parties to this Agreement with respect to, provide any necessary information with respect to (and, in the case of correspondence, provide the other parties (or their counsel) copies of), all filings made by such party with any Governmental Entity or any other information supplied by such party to, or correspondence with, a Governmental Entity in connection with this Agreement and the Merger. Each party to this Agreement shall promptly inform the other parties to this Agreement, and if in writing, furnish the other party with copies of (or, in the case of oral communications, advise the other party orally of) any communication from any Governmental Entity regarding the Merger, and permit the other party to review and discuss in advance, and consider in good faith the views of the other party in connection with, any proposed communication with any such Governmental Entity. If any party to this Agreement or any Representative of such parties receives a request for additional information or documentary material from any Governmental Entity with respect to the Merger, then such party will use reasonable best efforts to make, or cause to be made, promptly and after consultation with the other parties to this Agreement, an appropriate response in substantial compliance with such request. Neither party shall participate in any meeting or

- 48 -

teleconference with any Governmental Entity where material issues would likely be discussed in connection with this Agreement and the Merger unless it consults with the other party in advance and, to the extent permitted by such Governmental Entity, gives the other party the opportunity to attend and participate thereat. Each party shall furnish the other party with copies of all correspondence, filings and communications (and memoranda setting forth the substance thereof) between it and any such Governmental Entity with respect to this Agreement and the Merger, and furnish the other party with such necessary information and reasonable assistance as the other party may reasonably request in connection with its preparation of necessary filings or submissions of information to any such Governmental Entity; provided, however, that materials provided pursuant to this Section 5.6 may be redacted (i) to remove references concerning the valuation of the Company and the Merger or other confidential information, (ii) as necessary to comply with contractual arrangements, and (iii) as necessary to address reasonable privilege concerns.

(c) The Company and Parent shall use reasonable best efforts to file, as promptly as practicable, but in any event no later than ten (10) business days after the date of this Agreement, all notifications required under the HSR Act. In the event that the parties receive a request for information or documentary material pursuant to the HSR Act (a “Second Request”), the parties will use their respective reasonable best efforts to respond to such Second Request as promptly as practicable, and counsel for both parties will closely cooperate during the entirety of any such Second Request review process.

(d) In furtherance, and not in limitation of the foregoing, Parent shall (and shall use reasonable best efforts to cause Pennsylvania to) take any and all action necessary to obtain expiration or early termination of the waiting period under the HSR Act with respect to the transactions contemplated by this Agreement and the Pennsylvania Merger Agreement, including but not limited to: (i) selling or otherwise disposing of, or holding separate and agreeing to sell or otherwise dispose of, assets, categories of assets or businesses of the Company or Parent or their respective Subsidiaries; (ii) terminating, entering into or modifying existing relationships, contractual rights or obligations of the Company or Parent or their respective Subsidiaries; (iii) terminating any venture or other arrangement; or (iv) creating any relationship, contractual rights or obligations of the Company or Parent or their respective Subsidiaries (each a “Divestiture Action”) in an effort to ensure that no Governmental Entity enters any order, decision, judgment, decree, ruling, injunction (preliminary or permanent), or establishes any law, rule, regulation or other action preliminarily or permanently restraining, enjoining or prohibiting the consummation of the Merger. Parent may condition the entry of a Divestiture Action on consummation of the Merger. In the event a Governmental Entity institutes (or threatens to institute) any action challenging the transactions contemplated by this Agreement as violative of any U.S. antitrust law, Parent and the Company shall cooperate and use reasonable best efforts to vigorously contest and resist any such Action, and to have vacated, lifted, reversed, or overturned any decree, judgment, injunction or other order whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents, or restricts consummation of the Merger, including by pursuing administrative or judicial appeal, and Parent shall take all action necessary, including but not limited to any Divestiture Action, in an effort to resolve such action so as to permit such consummation prior to the End Date. To assist Parent in complying with its obligations set forth in this Section, at Parent’s request the Company shall, and shall cause its Subsidiaries to, enter into one or more agreements prior to the Closing with respect to any

- 49 -

Divestiture Action; provided, however, that the consummation of the transactions provided for in any such agreement for a Divestiture Action shall be conditioned upon the Closing. Notwithstanding anything in this Agreement to the contrary, nothing in this Section or elsewhere shall require, or be deemed to require, Parent to take or agree to take any Divestiture Action if doing so would, individually or in the aggregate, be reasonably likely to result in a Company Material Adverse Effect or a material adverse effect on Parent.

(e) Notwithstanding anything to the contrary contained herein, the parties agree that it is Parent’s sole right to devise the strategy for all filings, notifications, submissions and communications in connection with any filing, notice, petition, statement, registration, submission of information, application or similar filing subject to this Section 5.6.

Section 5.7 Takeover Statutes. If any “moratorium,” “control share acquisition,” “fair price,” “supermajority,” “affiliate transactions” or “business combination statute or regulation” or other similar state anti-takeover Laws and regulations may become, or may purport to be, applicable to the Merger or any other transactions contemplated hereby, each of the Company and Parent shall grant such approvals and take such actions as are reasonably necessary so that the transactions contemplated hereby may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to eliminate or minimize the effects of such statute or regulation on the transactions contemplated hereby.

Section 5.8 Public Announcements. Parent and the Company shall use reasonable best efforts to develop a joint communications plan and each party shall use reasonable best efforts to ensure that all press releases and other public statements with respect to the transactions contemplated hereby, to the extent they have not been previously issued or disclosed, shall be consistent with such joint communications plan. Unless otherwise required by applicable Law or by obligations pursuant to any listing agreement with or rules of any securities exchange, each party shall consult with each other before issuing any press release or public statement with respect to the Merger and, subject to the requirements of applicable Law or the rules of any securities exchange, shall not issue any such press release or public statement prior to such consultation. Parent and the Company agree to issue a mutually acceptable initial joint press release announcing this Agreement.

Section 5.9 Indemnification and Insurance.

(a) Parent and Merger Sub agree that all rights to exculpation, indemnification and advancement of expenses for acts or omissions occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, now existing in favor of the current or former, directors, officers or employees, as the case may be, of the Company or its Subsidiaries as provided in their respective certificate of incorporation or bylaws or other organizational documents or in any agreement shall survive the Merger and shall continue in full force and effect. For a period of six years from the Effective Time, Parent and the Surviving Corporation shall maintain in effect any and all exculpation, indemnification and advancement of expenses provisions of the Company’s and any of its Subsidiaries’ certificate of incorporation and bylaws or similar organizational documents in effect immediately prior to the Effective Time or in any indemnification agreements of the Company or its Subsidiaries with any of their respective current or former directors, officers or employees in effect immediately prior to the

- 50 -

Effective Time, and shall not amend, repeal or otherwise modify any such provisions or the exculpation, indemnification or advancement of expenses provisions of the Surviving Corporation’s certificate of incorporation and bylaws in any manner that would adversely affect the rights thereunder of any individuals who immediately before the Effective Time were current or former directors, officers or employees of the Company or any of its Subsidiaries; provided, however, that all rights to indemnification in respect of any Action pending or asserted or any claim made within such period shall continue until the disposition of such Action or resolution of such claim.

(b) The Surviving Corporation shall (and Parent shall cause the Surviving Corporation to), to the fullest extent permitted under applicable Law, indemnify and hold harmless (and advance funds in respect of each of the foregoing) each current and former director, officer or employee of the Company or any of its Subsidiaries and each person who served as a director, officer, member, trustee or fiduciary of another corporation, partnership, joint venture, trust, pension or other employee benefit plan or enterprise if such service was at the request or for the benefit of the Company or any of its Subsidiaries (each, together with such person’s heirs, executors or administrators, an “Indemnified Party”), in each case against any costs or expenses (including advancing attorneys’ fees and expenses in advance of the final disposition of any claim, suit, proceeding or investigation to each Indemnified Party to the fullest extent permitted by applicable Law; provided, however, that the Indemnified Party to whom expenses are advanced provides an undertaking consistent with the Company Organizational Documents to repay such amounts if it is ultimately determined that such person is not entitled to indemnification), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any actual or threatened claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative (an “Action”), arising out of, relating to or in connection with any action or omission by them in their capacities as such occurring or alleged to have occurred whether before or after the Effective Time (including acts or omissions in connection with such Indemnified Party serving as an officer, director, employee or other fiduciary of any entity if such service was at the request or for the benefit of the Company). In the event of any such Action, the Surviving Corporation shall cooperate with the Indemnified Party in the defense of any such Action.

(c) For a period of six years from the Effective Time, Parent shall cause to be maintained in effect the coverage provided by the policies of directors’ and officers’ liability insurance and fiduciary liability insurance in effect as of the date hereof by the Company and its Subsidiaries or provide substitute policies for the Company and its current and former directors and officers who are currently covered by the directors’ and officers’ liability insurance and fiduciary liability insurance coverage in effect as of the date hereof by the Company and its Subsidiaries, in either case, of not less than the existing coverage and have other terms not less favorable to the insured persons than the directors’ and officers’ liability insurance and fiduciary liability insurance coverage with respect to matters existing or arising on or before the Effective Time; provided, however, that Parent shall not be required to pay annual premiums in excess of 300% of the last annual premium paid by the Company prior to the date hereof in respect of the coverages (the “Maximum Amount”) required to be obtained pursuant hereto, but in such case shall purchase as much coverage as reasonably practicable for such amount. Notwithstanding anything to the contrary herein, the Company may, prior to the Effective Time, purchase a “tail policy” with respect to acts or omissions occurring or alleged to have occurred prior to the

- 51 -

Effective Time that were committed or alleged to have been committed by such Indemnified Parties in their capacity as such; provided that such “tail policy” shall provide coverage in an amount not less than the existing coverage and to have other terms not less favorable to the Indemnified Parties than the directors’ and officers’ liability insurance and fiduciary liability insurance coverage in effect as of the date hereof by the Company and its Subsidiaries; provided further in no event shall the cost of such policy, if purchased by the Company, exceed six (6) times the Maximum Amount and, if such a “tail policy” is purchased, Parent shall have no further obligations under this Section 5.9(c). The Surviving Corporation shall maintain such policies in full force and effect, and continue to honor the obligations thereunder.

(d) Parent shall pay all reasonable expenses, including reasonable attorneys’ fees, that may be incurred by any Indemnified Party in enforcing the indemnity and other obligations provided in this Section 5.9.

(e) The rights of each Indemnified Party shall be in addition to, and not in limitation of, any other rights such Indemnified Party may have under the certificate of incorporation or bylaws or other organizational documents of the Company or any of its Subsidiaries or the Surviving Corporation, any other indemnification arrangement, the DGCL or otherwise.

(f) The obligations of Parent and the Surviving Corporation under this Section 5.9 shall not be terminated, amended or modified in any manner so as to adversely affect any Indemnified Party (including their successors, heirs and legal representatives) to whom this Section 5.9 applies without the consent of such Indemnified Party. It is expressly agreed that, notwithstanding any other provision of this Agreement that may be to the contrary, (i) the Indemnified Parties to whom this Section 5.9 applies shall be third-party beneficiaries of this Section 5.9, and (ii) this Section 5.9 shall survive consummation of the Merger and shall be enforceable by such Indemnified Parties and their respective successors, heirs and legal representatives against Parent and the Surviving Corporation and their respective successors and assigns.

(g) In the event the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other Person and is not 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, the Surviving Corporation shall cause proper provision to be made so that the successors and assigns of the Surviving Corporation assume the obligations set forth in this Section 5.9.

Section 5.10 Control of Operations. Without in any way limiting any party’s rights or obligations under this Agreement, the parties understand and agree that (a) nothing contained in this Agreement shall give Parent or the Company, directly or indirectly, the right to control or direct the other party’s operations prior to the Effective Time and (b) prior to the Effective Time, each of the Company and Parent shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its operations.

(a) Parent shall use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, advisable or proper to arrange, and obtain the Financing on the terms and conditions described in the Commitment Letters by the Closing, including using reasonable best efforts to (i) maintain in effect each Commitment Letter (provided that such Commitment Letters may be amended, supplemented, modified and replaced as set forth below), (ii) satisfy on a timely basis all conditions applicable to Parent to the funding of the Financing set forth in each Commitment Letters and within Parent’s control (other than any condition where the failure to be so satisfied is a direct result of the Company’s failure to furnish information to Parent) and (iii) negotiate and enter into definitive agreements with respect thereto on the terms and conditions contemplated by the Commitment Letters (including any “flex” provisions), or terms and conditions not materially less favorable (taken as a whole) to Parent than the terms and conditions contemplated by each Commitment Letters (including any “flex” provisions) which terms and conditions would not reasonably be expected to prevent, materially delay or materially impede the consummation of the Financing or the Merger.

(b) Prior to the Closing, Parent shall not, and shall not permit Merger Sub to, agree to or permit any termination, amendment, replacement, supplement or other modification of, or waive any of its material rights under, any Commitment Letter without the Company’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed); provided that Parent and Merger Sub may, without the Company’s prior written consent (x) enter into any amendment, replacement, supplement or other modification to or waiver of any provision of any Commitment Letter that does not contain any provisions that would reasonably be expected to prevent, materially delay or materially impede the consummation of the Financing or the Merger; and (y) amend, replace, supplement or otherwise modify any Commitment Letter (subject to the terms and conditions thereof) to add lenders, lead arrangers, bookrunners, syndication agents or similar entities who had not executed such Commitment Letters as of the date of this Agreement. Upon any such amendment, replacement, supplement or modification, the term “Commitment Letters” shall include any such Commitment Letter as so amended, replaced, supplemented or modified. For the avoidance of doubt, each of Parent and Merger Sub may, if it so determines in its discretion, arrange for alternative financing for the Merger from a third party or parties reasonably satisfactory to Parent (and thereafter the “Commitment Letter” (as modified in singular form if the context requires) and the “Financing” as defined herein shall refer to such financing commitment in respect of such alternative financing) on terms and conditions not materially less favorable to Parent (taken as a whole), if such alternative financing does not contain any provisions that would reasonably be expected to prevent, materially delay or materially impede the consummation of the Financing or the Merger. If any such alternate financing is obtained Parent shall promptly and in any event within one Business Day provide the Company with a copy of any new financing commitment (redacted for provisions related to fees, pricing, “flex” terms, any other economic terms and other confidential terms but not, for the avoidance of doubt, as to any matters related to conditionality) that provides for such alternative financing.

(c) In the event any portion of the Financing becomes unavailable on the terms and conditions described in or contemplated by the Commitment Letters (including the “flex” provision) for any reason, or Parent and Merger Sub determines in their discretion, to

- 53 -

arrange for alternative financing for the Merger from a third party or parties reasonably satisfactory to Parent on terms and conditions not materially less favorable to Parent (taken as a whole), provided that such alternative financing does not contain any provisions that would reasonably be expected to prevent, materially delay or materially impede the consummation of the Merger, Parent shall use its reasonable best efforts to arrange and obtain alternative financing from the same or alternative sources reasonably satisfactory to Parent (the “Alternative Financing”) in an amount sufficient and on terms and conditions not materially less favorable (taken as a whole) than those described in the Commitment Letters (which terms and conditions would not reasonably be expected to prevent, materially delay or materially impede the consummation of the Financing or the Merger) to enable Parent to fund the payment of the cash component of the aggregate Merger Consideration (and thereafter the “Commitment Letters” and the “Financing” as defined herein shall refer to such financing commitment for the Alternative Financing). If an Alternative Financing is required in accordance with this Section 5.11, Parent shall promptly, and in any event within one Business Day provide the Company with a copy of any new financing commitment (redacted for provisions related to fees, pricing, “flex” terms, any other economic terms and other confidential terms but not, for the avoidance of doubt, as to any matters related to conditionality) that provides for such Alternative Financing, and thereafter the “Commitment Letters” (as modified to singular form if the context requires) as defined herein shall refer to such financing commitment in respect of the Alternative Financing.

(d) Prior to the Effective Time, the Company shall, and shall cause its Subsidiaries and their respective Representatives to (at the sole expense of Parent), provide all cooperation that is usual and customary for similar financings and otherwise as may be reasonably necessary, proper or advisable in connection with the Financing or any Alternative Financing by Parent or any of its affiliates in connection with the Merger as may be reasonably requested by Parent or its Representatives. Without limiting the generality of the foregoing, the Company shall, and shall cause its Subsidiaries and their respective Representatives to (i) furnish, as promptly as practicable, the report of the Company’s auditor on the most recently available audited consolidated financial statements of the Company and its Subsidiaries and use its reasonable best efforts to obtain the consent of such auditor to the use of such report in accordance with normal custom and practice and use reasonable best efforts to cause such auditor to provide customary comfort letters (which shall provide “negative assurance” comfort) to the underwriters, initial purchasers or placement agents, as applicable, in connection with any such Financing or Alternative Financing; (ii) furnish, as promptly as practicable (A) any financial statements, schedules or other financial data or information relating to the Company and its Subsidiaries reasonably requested by Parent or its Representatives as may be necessary, proper or advisable to consummate the Financing or the Alternative Financing, including financial statements, financial data, audit reports and other information of the type required by Regulation S-X and Regulation S-K promulgated under the Securities Act for a registered public offering or as may be necessary, proper or advisable to consummate the offering(s) of debt securities contemplated by the Commitment Letters, and (B) drafts of such “comfort” letters which such independent accountants are prepared to issue upon completion of customary procedures, each in form and substance customary for offering(s) of debt securities contemplated by the Commitment Letters; (iii) use commercially reasonable efforts to facilitate contact between (x) senior management and advisors, including auditors, of the Company and (y) the proposed lenders, lead arrangers, bookrunners, underwriters, initial purchasers or placement agents, as applicable, and/or Parent’s or any of its affiliate’s auditors in connection with, the

- 54 -

Financing or any Alternative Financing, at reasonable times and upon reasonable advance notice; (iv) use commercially reasonable efforts to make available, at reasonable times and upon reasonable advance notice, the necessary employees and advisors of the Company and its Subsidiaries to provide reasonable assistance with the preparation of business projections, financing documents and offer materials by Parent and its affiliates; (v) provide customary information, documents, authorization letters and certificates, enter into agreements and take other actions that are or may be customary in connection with the Financing or any Alternative Financing (including all documentation and other information required by bank regulatory authorities under applicable “know-your-customer” and anti-money laundering rules and regulations); (vi) use commercially reasonable efforts to provide assistance in the preparation of one or more confidential information memoranda, prospectuses, offering memoranda, private placement memoranda, and other marketing and syndication materials (including with respect to the presence or absence of material non-public information and the accuracy of the information contained therein) reasonably requested by Parent or any of its affiliates; (vii) use commercially reasonable efforts to assist Parent in ensuring that the syndication efforts benefit from the existing banking relationships of the Company and its Subsidiaries; (viii) permit the reasonable use by Parent and its Affiliates of the Company’s and its Subsidiaries’ logos for syndication and underwriting, as applicable, of financing, provided that such logos are used solely in a manner that is not intended to nor reasonably likely to harm or disparage the Company or any of its Subsidiaries or the reputation or goodwill of the Company or any of its Subsidiaries and its or their marks; (ix) participate as necessary in a reasonable number of meetings, presentations, customary one-on-one sessions and road shows with parties acting as lead arrangers, bookrunners, underwriters, initial purchasers or other agents for, and prospective lenders and investors of, the Financing or any Alternative Financing and in drafting sessions and due diligence sessions, as applicable (including the reasonable participation in such meetings by the Company’s senior management with appropriate seniority and expertise); (x) use commercially reasonable efforts to assist in procuring any necessary rating agency ratings or approvals and participating in a reasonable number of sessions with rating agencies; (xi) delivering any certificates or similar documents as may be reasonably requested by Parent; and (xii) not commence or effect any offering, placement or arrangement of any debt securities or bank financing competing with the proposed financing of Parent and its Affiliates (and not permit any such offering, placement or arrangements to occur on its behalf); provided that (x) none of the Company or any of its Subsidiaries shall be required to pay any commitment or other fee or incur any other liability or obligation in connection with the Financing or any Alternative Financing or to take any action that would be prohibited by any applicable Law or cause a default of, or breach under, or otherwise violate any Company Material Contract, in each case except for any payment, incurrence or action that is conditioned upon, and shall not take effect until, the Effective Time, and (y) no obligations of the Company or any of its Subsidiaries under any certificate, opinion, contract, indenture or other document or instrument delivered pursuant to this Section 5.11 shall be effective until the Effective Time, and none of the Company or any of its Subsidiaries shall be required to take any action pursuant to this Section 5.11 under any certificate, opinion, contract, indenture or other document or instrument that is not contingent upon the Closing or that would be effective prior to the Effective Time. The Company will use commercially reasonable efforts to provide to Parent and the Financing Sources such information as may be reasonably necessary so that the marketing materials as they relate to the Company and its affiliates are complete and correct in all material respects.

- 55 -

(e) The Company shall use reasonable best efforts to (i) obtain drafts of customary payoff letters from third-party lenders and trustees with respect to the indebtedness of the Company and its Subsidiaries specified in Section 5.11 of the Company Disclosure Letter no later than five business days prior to the Effective Time and (ii) deliver or cause to be delivered executed versions of such payoff letters to Parent promptly thereafter, and in any event no later than two business days prior to the Effective Time. At the Effective Time, subject to Parent making available necessary funds to do so, the Company shall use all reasonable best efforts to, and to cause its Subsidiaries to, permanently (x) terminate the indebtedness specified in Section 5.11 of the Company Disclosure Letter and all related contracts to which the Company or any of its Subsidiaries is a party and (y) make satisfactory arrangements for the release of any Encumbrances on assets relating to such terminated indebtedness.

(f) Notwithstanding anything in this Section 5.11 to the contrary, in fulfilling its obligations pursuant to this Section 5.11, (i) none of the Company, its Subsidiaries or its Representatives shall be required to pay any commitment or other fee, provide any security or incur any other liability in connection with any financing prior to the Effective Time, (ii) any requested cooperation shall not unreasonably interfere with the ongoing operations of the Company and its Subsidiaries, and (iii) Parent shall reimburse the Company for all reasonable and documented out-of-pocket costs incurred by the Company or any of its Subsidiaries in connection with such cooperation. Parent shall indemnify and hold harmless the Company and its Subsidiaries from and against any and all losses or damages actually suffered or incurred by them directly in connection with the arrangement of any such financing (other than to the extent related to information provided by the Company, its Subsidiaries or their respective Representatives), except in the event such loss or damage arises out of or results from the gross negligence, willful misconduct, bad faith or intentional breach of its obligations hereunder by the Company or its Subsidiaries.

Section 5.12 Standstill Waivers. The Company shall not take any action which would reasonably be expected to have the effect of revoking, modifying or terminating the Standstill Waivers; provided that upon termination of this Agreement in accordance with Section 7.1, the Standstill Waivers shall not be applicable and shall have no force or effect (except that the Standstill Waivers with respect to the transactions contemplated by the Pennsylvania Merger Agreement shall be irrevocable, and shall survive any termination of this Agreement).

Section 5.13 Transaction Litigation. The Company shall give Parent the opportunity to participate (at Parent’s expense and subject to a customary joint defense agreement) in the Company’s defense or settlement of any stockholder litigation against the Company and/or its directors or executive officers relating to the transactions contemplated by this Agreement, including the Merger. The Company agrees that it shall not settle or offer to settle any litigation commenced prior to or after the date of this Agreement against the Company or its directors, executive officers or similar persons by any stockholder of the Company relating to this Agreement, the Merger, or any other transaction contemplated hereby without the prior written consent of Parent.

Section 5.14 Section 16 Matters. Assuming that the Company delivers to Parent, in a timely fashion prior to the Effective Time, all requisite information necessary for Parent to take the actions contemplated by this Section 5.14, the Company and Parent each shall take all such

ARTICLE VII.

TERMINATION

Section 7.1 Termination or Abandonment. Notwithstanding anything in this Agreement to the contrary, this Agreement may be terminated and abandoned at any time prior to the Effective Time, whether before or after any approval of the Merger by the stockholders of the Company:

(a) by the mutual written consent of the Company, Parent and Merger Sub duly authorized (i) with respect to Parent and Merger Sub, by their respective boards of directors or other governing body, and (ii) with respect to the Company, by the Company Board upon the recommendation of the Company Special Committee if then in existence or otherwise by a majority of the Company’s Independent Directors;

(c) by either the Company (duly authorized by the Company Board upon the recommendation of the Company Special Committee if then in existence or otherwise by a majority of the Company’s Independent Directors) or Parent, if an injunction shall have been entered permanently restraining, enjoining or otherwise prohibiting the consummation of the Merger and such injunction shall have become final and nonappealable; provided, however, that the right to terminate this Agreement under this Section 7.1(c) shall not be available to a party if such injunction was due to the failure of such party to perform any of its obligations under this Agreement;

- 59 -

(d) by either the Company (duly authorized by the Company Board upon the recommendation of the Company Special Committee if then in existence or otherwise by a majority of the Company’s Independent Directors) or Parent, if the Company Stockholders’ Meeting (including any adjournments or postponements thereof) shall have concluded and the Company Stockholder Approval shall not have been obtained;

(e) by the Company (duly authorized by the Company Board upon the recommendation of the Company Special Committee if then in existence or otherwise by a majority of the Company’s Independent Directors), if Parent or Merger Sub shall have breached or failed to perform any of its representations, warranties, covenants or other agreements contained in this Agreement, which breach or failure to perform (i) would result in a failure of a condition set forth in Section 6.2(a) or Section 6.2(b) and (ii) by its nature, cannot be cured prior to the End Date or, if such breach or failure is capable of being cured by the End Date, Parent does not cure such breach or failure within forty-five (45) calendar days after receiving written notice from the Company describing such breach or failure in reasonable detail (provided that the Company is not then in breach of any representation, warranty, covenant or other agreement contained herein such that a condition set forth in Section 6.3(a) or Section 6.3(b) would not be satisfied);

(f) by Parent, if the Company shall have breached or failed to perform any of its representations, warranties, covenants or other agreements contained in this Agreement, which breach or failure to perform (i) would result in a failure of a condition set forth in Section 6.3(a) or Section 6.3(b) and (ii) by its nature, cannot be cured prior to the End Date or, if such breach or failure is capable of being cured by the End Date, the Company does not cure such breach or failure within forty-five (45) calendar days after receiving written notice from Parent describing such breach or failure in reasonable detail (provided that Parent is not then in breach of any representation, warranty, covenant or other agreement contained herein such that a condition set forth in Section 6.2(a) or Section 6.2(b) would not be satisfied); and

Section 7.3 Breakup Fee; Expenses.

(a) If this Agreement is terminated by either Parent or the Company pursuant to Section 7.1(d) or by Parent pursuant to Section 7.1(g) as a result of a Company Adverse Recommendation Change due to an Intervening Event, the Company shall pay Parent up to $19,500,000 in respect of Parent’s expenses in connection with this Agreement (the “Expense

- 60 -

Reimbursement”), by wire transfer (to an account designated by Parent) in immediately available funds within two business days after such termination. If this Agreement is terminated (i) by Parent pursuant to Section 7.1(g) as a result of a Company Adverse Recommendation Change due to a Company Superior Proposal, or (ii) by Parent or the Company pursuant to Section 7.1(b) or Section 7.1(d), and in the case of any termination pursuant to this clause (ii), (A) a Company Takeover Proposal shall have been publicly announced or shall have become publicly known, and not withdrawn at least fifteen (15) business days prior to the Company Stockholders’ Meeting and (B) at any time on or prior to the twelve month anniversary of such termination the Company or any of its Subsidiaries enters into a definitive agreement with respect to any Company Takeover Proposal or the transactions contemplated by any Company Takeover Proposal are consummated, the Company shall pay Parent the Termination Fee (less any amounts previously paid to Parent in respect of the Expense Reimbursement), by wire transfer (to an account designated by Parent) in immediately available funds (1) in the case of clause (i), within two business days of such termination, in the case of clause (ii) the Expense Reimbursement within two business days of such termination and the Termination Fee (less any amounts previously paid to Parent in respect of the Expense Reimbursement) upon the earlier of entering into such definitive agreement with respect to a Company Takeover Proposal or the consummation of the transactions contemplated by a Company Takeover Proposal. “Termination Fee” shall mean a cash amount equal to $98,000,000. Notwithstanding anything to the contrary in this Agreement, if the Termination Fee shall become due and payable in accordance with this Section 7.3(a), from and after such termination and payment of the Termination Fee pursuant to and in accordance with this Section 7.3(a), the Company shall have no further liability of any kind for any reason in connection with this Agreement or the termination contemplated hereby other than as provided under this Section 7.3(a), except in the case of fraud or a willful and material breach by the Company of this Agreement. Each of the parties hereto acknowledges that the Termination Fee and Expense Reimbursement are not intended to be a penalty, but rather are liquidated damages in a reasonable amount that will compensate Parent in the circumstances in which such Termination Fee and/or Expense Reimbursement are due and payable and which do not involve fraud or willful and material breach, for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the transactions contemplated hereby, which amount would otherwise be impossible to calculate with precision. In no event shall Parent be entitled to more than one payment of the Termination Fee in connection with a termination of this Agreement pursuant to which the Termination Fee is payable, and if the Termination Fee is payable at such time as Parent has already received payment from the Company in respect of Expense Reimbursement, the amount of Expense Reimbursement actually received by Parent shall be deducted from the Termination Fee.

(b) Each of the Company, Parent and Merger Sub acknowledges that the agreements contained in this Section 7.3 are an integral part of the transactions contemplated hereby, and that, without these agreements, the Company, Parent and Merger Sub would not enter into this Agreement. Accordingly, if the Company fails to pay in a timely manner any amount due pursuant to Section 7.3(a), then (i) the Company shall reimburse Parent for all costs and expenses (including disbursements and reasonable fees of counsel) incurred in the collection of such overdue amount, including in connection with any related Actions commenced and (ii) the Company shall pay to Parent interest on such amount from and including the date payment of

- 61 -

such amount was due to but excluding the date of actual payment at the prime rate set forth in The Wall Street Journal in effect on the date such payment was required to be made plus 2%.

Section 8.8 Assignment; Binding Effect. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned or delegated by any of the parties hereto without the prior written consent of the other parties; provided, however, that each of Merger Sub and Parent may assign any of their rights hereunder to a wholly owned direct or indirect Subsidiary of Parent without the prior written consent of the Company, but no such assignment shall relieve Parent or Merger Sub of any of its obligations hereunder and that as a condition of such assignment, the assignee expressly assumes the obligations of the assignor. Subject to the first sentence of this Section 8.8, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns. Any purported assignment not permitted under this Section shall be null and void.

Section 8.9 Severability.

If any provision of this Agreement is so broad as to be unenforceable, such provision shall be interpreted to be only so broad as is enforceable.

Section 8.10 Entire Agreement. This Agreement together with the exhibits hereto, schedules hereto and the Confidentiality Agreement constitute the entire agreement, and supersede all other prior agreements and understandings, both written and oral, between the

- 65 -

parties, or any of them, with respect to the subject matter hereof and thereof, and this Agreement is not intended to grant standing to any person other than the parties hereto.

Section 8.11 Amendments; Waivers. At any time prior to the Effective Time, any provision of this Agreement may be amended or waived by the parties hereto (which amendment or waiver must be in writing and signed) by action taken or authorized (i) with respect to Parent and Merger Sub, by or on behalf of their respective board of directors or other governing body and (ii) with respect to the Company, by or on behalf of the Company Board, upon the recommendation of the Company Special Committee if then in existence or otherwise by a majority of the Independent Directors of the Company; provided, however, that after receipt of Company Stockholder Approval, no such amendment or waiver shall be made that would reduce the amount or change the type of consideration into which each share of Company Common Stock shall be converted upon consummation of the Merger or that would otherwise by applicable Law or in accordance with the rules and regulations of the NYSE require further approval of the stockholders of the Company, without approval of such stockholders of the Company. Notwithstanding the foregoing, no failure or delay by any party hereto in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder. Notwithstanding anything herein to the contrary, Sections 8.5, 8.6 and 8.13 and this sentence may not be modified, waived or terminated in a manner that is adverse to the Financing Sources without the prior written consent of each Financing Source.

Notwithstanding the foregoing, (1) each Financing Source shall be an express third party beneficiary of and shall be entitled to rely upon Sections 8.5 and 8.6 hereof, the last sentence of Section 8.11 and this Section 8.13, and each Financing Party may enforce such provisions, and (2) Pennsylvania shall be an express third party beneficiary of and shall be entitled to rely upon Section 5.12 (only with respect to the transactions contemplated by the Pennsylvania Merger Agreement). In addition, the Company agrees, on behalf of itself and its Affiliates, stockholders and Representatives (collectively, the “Company Related Parties”), that the Financing Sources under the Commitment Letters and their Affiliates, stockholders and Representatives and each of their successors and assigns (collectively, the “Financing Parties”) shall be subject to no liability or claims (whether legal or equitable, arising under contract, tort or otherwise) by the Company Related Parties arising out of or relating to this Agreement, the Commitment Letters, the Financing or the transactions

Exhibit A to the Merger Agreement

Term Sheet for Overriding Royalty Interests (the “Royalty Trust Term Sheet”)


Capitalized Terms		Capitalized terms used herein but not defined shall have the meaning set forth in the Agreement and Plan of Merger by and among Freeport-McMoRan Copper & Gold Inc. (“Parent”), INAVN Corp. (“Merger Sub”) and McMoRan Exploration Co. (the “Company”), dated December 5, 2012 (the “Agreement”).

Transaction		Prior to the Closing, Parent (with the reasonable cooperation of the Company, as requested by Parent) will cause the Trust to be created pursuant to the Trust Agreement. The Royalty Trust Units will be issued and distributed in a manner consistent with the terms of the Agreement and this Term Sheet. The total number of Royalty Trust Units issued by the Trust will be equal to the fully diluted number of shares of the Company Common Stock outstanding immediately prior to the effective time of the merger (for the avoidance of doubt, (i) excluding any shares of Company Common Stock issuable in respect of Company Stock Awards, which Company Stock Awards will not receive the Merger Consideration in connection with the Merger, (ii) including any shares beneficially owned by Parent or its subsidiaries or otherwise to be cancelled at the effective time of the Merger and (iii) calculated based on the assumption that all Company Convertible Securities receive the maximum make-whole premium applicable to them in connection with the merger upon conversion (as calculated as of the effective time of the Merger), as set forth in their respective underlying agreements). All Royalty Trust Units issued by the Trust and not distributable with respect to shares of Company Common Stock in connection with the merger shall be held by Parent upon the closing of the Merger, with the applicable number of Royalty Trust Units to remain subject to the ongoing obligation of Parent to deliver the Royalty Trust Units upon conversion of the outstanding Company Convertible Securities, as set forth in their respective underlying agreements. For the avoidance of doubt, in no event shall any holder of a Company Stock Award be issued Royalty Trust Units as consideration for such Company Stock Award. Pursuant to a master conveyance agreement (the “Master Conveyance”), Parent will cause the Company to convey to the Trust overriding royalty interests in the Subject Interests (as defined below). The Master Conveyance will be effective as of the Closing and in form and substance consistent with this term sheet and otherwise satisfactory to Company and Parent.

Subject Interests		All of Company’s right, title and interest in and to leases listed in the Master Conveyance (the “Subject Interests”) will be subject to the overriding royalty interests, subject to the restrictions described under “Overriding Royalty Percentage” below. The Subject Interests will generally include all of Company’s existing shallow water Gulf of Mexico and onshore Gulf Coast ultra deep (wells completed at a depth of 18,000 feet or below) exploration prospects that are not classified as proved reserves or probable or possible reserves as of the signing of the merger agreement and without limitation will include all of Company’s rights currently owned or (with respect to which the Company is in the process of acquiring) hereafter acquired by


		the Company or any of its Affiliates within the prospect areas set forth on Schedule A. The Company and Parent will cooperate in good faith between signing of the Merger Agreement and Closing to identify with specificity the leases and blocks in which the Company has an interest included within the Subject Interests, and the Master Conveyance will include references to such specific leases and blocks. To the extent any such rights which the Company is in the process of acquiring are acquired by the Company or any of its Affiliates after the execution of the original Master Conveyance, such rights will be transferred to the Trust pursuant to a subsequently executed conveyance agreement in substantially the same form and substance as the Master Conveyance. None of the Subject Interests have any associated production at the time of the signing of the merger agreement.

Overriding Royalty Percentage		The Trust will receive a 5% gross overriding royalty interests in and to the hydrocarbons saved and produced from the Subject Interests, net to the Company’s working interest.

Drilling, Operating and Development Costs		The overriding royalty interests will be free and clear of any and all drilling, development and operating costs and expenses; provided, however, that the overriding royalty interest hydrocarbons will be valued at the wellhead and neither the Company nor Parent will have any duty to transport or market the produced hydrocarbons away from the wellhead without cost, and provided further that the overriding royalty interest hydrocarbons will be subject to and bear production and other like taxes. The Parent and Company will include customary language protective of the trust in the Trust Agreement and any other definitive documentation creating the overriding royalty interest with respect to any transportation or marketing of hydrocarbons that Parent or its controlled Affiliates may elect to provide with respect to hydrocarbons produced from the Subject Interests and the price utilized for purposes of calculating the overriding royalty interest.

No Obligation to Drill or Develop		The Trust will have no ability to influence the exploration or development of the Subject Interests. Parent will have no obligation to commit or expend drilling, exploration or development capital with respect to the Subject Interests. In addition, Parent will have the right to elect not to participate in drilling or other operations conducted by other working interest owners with respect to the Subject Interests.

Term and Termination		The Trust will terminate on the earlier of (i) the 20th anniversary of the Closing, (ii) the sale of all of the royalty interests, or (iii) upon a vote of the holders of 80% (which after the fifth anniversary of the Closing, shall be reduced to 66-2/3%) or more of the outstanding Trust Units held by persons other than Parent or any of its affiliates, at a duly called meeting of Trust Unit holders at which a quorum is present. The overriding royalty interests will terminate at the time of termination of the Trust. Parent will maintain a call right with respect to the outstanding Trust Units at $10 per unit, provided that the call right may not be exercised prior to the fifth anniversary of the Closing. At any time after the fifth (5th) anniversary of Closing, if the VWAP (as defined below) per Trust Unit is equal to $0.25 or less for the immediately preceding consecutive nine-month period, Parent will maintain the right to purchase all, but not less than all, of the outstanding Trust Units at a price of $0.25 per Trust Unit so long as Parent tenders payment within 30 days of such nine-month period. “VWAP” per


		Trust Unit on any trading day means the market price of one Trust Unit from the open of trading on the relevant trading day until the close of trading on the relevant trading day determined, using a volume-weighted average method. If the VWAP of the Trust Units can not be determined, the closing price of the Trust Units for the relevant trading day, on the market or system that the Trust Units are most commonly quoted or traded, will be substituted for the VWAP.

Trust Expenses		Parent will fund the administrative and reporting obligations of the Trust and all other expenses, up to a maximum amount of $350,000 per year. Prior to the Closing Date, the Company and Parent will discuss in good faith arrangements for Parent to lend money to the Trust to cover expenses in excess of such amount and the repayment terms of such indebtedness.

Listing; Registration		The Trust Units will be listed on a national securities exchange. The Trust Units will be registered on issuance and the Trust will therefore be subject to SEC reporting requirements.

Sale of Subject Interests		Parent may at any time transfer all or part of the Subject Interests subject to the transferee assuming all obligations (including the obligation to pay the overriding royalty) and rights with respect to such Subject Interests under the Trust.

Transferability		The Trust Units will be transferable, subject to customary procedural requirements.

Documentation		The Trust Units will be issued based on documentation reasonably acceptable to Company and Parent. In the absence of definitive documentation, the terms of this term sheet will control.
