WHEREAS, Parent, as the sole member of Merger Sub, has approved the execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby, including the Merger, and adopted this Agreement;

WHEREAS, for U.S. federal income tax purposes, it is intended that the Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and this Agreement is intended to be and is adopted as a “plan of reorganization” for purposes of Sections 354 and 361 of the Code;

At the Effective Time, upon the terms and subject to the conditions set forth in this Agreement and in accordance with the applicable provisions of the Delaware General Corporation Law (the “DGCL”) and the Delaware Limited Liability Company Act (the “DLLCA”), the Company shall be merged with and into Merger Sub, whereupon the separate corporate existence of the Company shall cease, and Merger Sub shall continue its existence under Delaware law as the surviving company in the Merger (the “Surviving Company”) and a direct wholly owned subsidiary of Parent.

Section 1.2 Closing. 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, on the fifth 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.

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 and the DLLCA 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 and the DLLCA (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 and the DLLCA. 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 Company, and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Company, all as provided under the DGCL and the DLLCA.

- 2 -

Surviving Company until thereafter amended in accordance with the provisions thereof and applicable Law.

ARTICLE II.

Section 2.1 Effect on Capital Stock.

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

(i) Limited Liability Company Interest of Merger Sub. The sole limited liability company interest of Merger Sub issued and outstanding immediately prior to the Effective Time shall remain outstanding as the sole limited liability company interest of the Surviving Company.

(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) 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.

(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 or upon the Effective Time, including shares of Company Common Stock that are deemed to be outstanding with respect to Company Electing Awards

- 3 -

pursuant to Section 2.5, but excluding any Cancelled Shares or Dissenting Shares (as defined herein) (each, a “Company Share”), shall be converted automatically into and shall thereafter represent the right to receive the following consideration (collectively, the “Merger Consideration”):

(A) for each Company Share with respect to which a Stock Election (as defined herein) has been validly made and not revoked pursuant to Section 2.3 (collectively, the “Stock Election Shares”), the right to receive from Parent the fraction of a share of validly issued, fully paid and nonassessable Parent Common Stock as is equal to the Exchange Ratio (collectively, the “Stock Consideration”);

(B) for each Company Share with respect to which a Cash Election (as defined herein) has been validly made and not revoked pursuant to Section 2.3 (collectively, the “Cash Election Shares”), the right to receive in cash from Parent an amount equal to the Per Share Amount (collectively, the “Cash Consideration”); and

(C) for each Company Share other than shares as to which a Cash Election or a Stock Election has been validly made and not revoked pursuant to Section 2.3 (collectively, the “Non-Election Shares”), the right to receive from Parent the Merger Consideration as is determined in accordance with Section 2.2.

(D) Definitions:

(1)

“Exchange Ratio” shall mean the quotient of (a) the Per Share Amount divided by (b) the Parent Closing Price.

(2)

“Per Share Amount” shall mean the sum of (A) $25.00 plus (B) the product of 0.6531 (the “Share Ratio”) times the Parent Closing Price.

(3)

“Parent Closing Price” shall mean the average, rounded to the nearest one tenth 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 ten trading days immediately preceding the date which is five trading days immediately prior to the date on which the Effective Time occurs.

(4)

“Cash Component” shall mean (A) $3,313,502,625 minus (B) the product of (1) $25.00 and (2) the sum of (a) the excess of (i) the number of Cancelled Shares over (ii) 14,960,232, (b) the number of Company Restricted Shares forfeited after the date of this Agreement and prior to the Effective Time, and (c) the number of Company Electing RSUs forfeited after the date of this Agreement and prior to the Effective Time plus (C) the product of (1) $25.00 and (2) the number of Company Shares issued with respect to Company Options outstanding on the

- 4 -

date hereof and set forth on the Company Disclosure Schedule exercised following the date hereof and prior to the Effective Time. The Cash Component excludes any amount paid or payable with respect to Company Cash RSUs and Company SARs.

All Company Shares 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 Company Shares represented by book-entry form (“Book-Entry Shares”) and each certificate that, immediately prior to the Effective Time, represented any such Company Shares (each, a “Certificate”) shall thereafter represent only the right to receive the Merger Consideration and the Fractional Share Cash Amount (as defined herein) into which the Company Shares represented by such Book-Entry Share or Certificate have been converted pursuant to this Section 2.1, as well as any dividends or other distributions to which holders of Company Shares become entitled in accordance with Section 2.4(d).

(iv) For the avoidance of doubt, the aggregate consideration to be paid by Parent in respect of the Merger Consideration to holders of Company Shares (including Company Electing Awards) shall be equal to the Cash Component (assuming all Dissenting Shares receive cash equal to the Per Share Amount) and 86,561,944 shares of Parent Common Stock (provided that the number of shares of Parent Common Stock to be issued shall be reduced by the product of (A) 0.6531 and (B) the sum of (1) the excess of the number of Cancelled Shares over 14,960,232, (2) the number of Company Restricted Shares forfeited after the date of this Agreement and prior to the Effective Time, and (3) the number of Company Electing RSUs forfeited after the date of this Agreement and prior to the Effective Time, and shall be increased by the product of (A) 0.6531 and (B) the number of Company Shares issued with respect to Company Options outstanding on the date hereof and set forth on the Company Disclosure Schedule exercised following the date hereof and prior to the Effective Time.

(b) Shares of Dissenting Stockholders. Notwithstanding anything in this Agreement to the contrary, any issued and outstanding Company Shares 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 all the provisions of the DGCL concerning the right of holders of Company Shares to demand appraisal of their (the “Appraisal Provisions”) Company Shares (“Dissenting Shares”), to the extent the Appraisal Provisions are applicable, shall not be converted into the right to receive the Merger Consideration as described in Section 2.1(a)(iii), 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 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 Company Shares shall thereupon be deemed to be Non-Election Shares for all purposes of this Agreement, unless such Dissenting Stockholder shall thereafter otherwise make a timely Election (as defined herein) under this Agreement. If any holder of Dissenting Shares shall have so failed to perfect or has effectively withdrawn or lost such Dissenting Stockholder’s right of appraisal after the Election Deadline (as defined herein), each of such Dissenting Stockholder’s Company Shares shall thereupon be deemed to have been converted into and to have become, as of the

- 5 -

Effective Time, the right to receive Stock Consideration or Cash Consideration, or a combination thereof, as determined by Parent in its sole discretion. The Company shall give Parent prompt notice of any demands for appraisal of Company Shares 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 Company Shares or Parent 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 Share Ratio 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) No Fractional Shares. No fractional shares of Parent Common Stock shall be issued in connection with the Merger, no certificates or scrip representing fractional shares of Parent Common Stock shall be delivered upon the conversion of Company Shares pursuant to Section 2.1(a)(iii), and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a holder of shares of Parent Common Stock. Notwithstanding any other provision of this Agreement, each holder of Company Shares converted pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Parent Common Stock (after aggregating all shares represented by the Certificates and Book-Entry Shares delivered by such holder) shall receive, in lieu thereof and upon surrender thereof, cash (without interest) in an amount determined by multiplying (i) the Parent Closing Price by (ii) the fraction of a share (after taking into account all Company Shares held by such holder at the Effective Time and rounded to the nearest one thousandth when expressed in decimal form) of Parent Common Stock to which such holder would otherwise be entitled (the “Fractional Share Cash Amount”). No such holder shall be entitled to dividends, voting rights or any other rights in respect of any fractional share of Parent Common Stock.

Section 2.2 Proration.

(a) Notwithstanding any other provision contained in this Agreement, the total number of Company Shares to be converted into Cash Consideration pursuant to Section 2.1(a)(iii) (which, for this purpose, shall be deemed to include the Dissenting Shares determined as of the Effective Time), (the “Cash Conversion Number”), shall be equal to the quotient obtained by dividing (i) the Cash Component by (ii) the Per Share Amount. All other Company Shares (other than Cancelled Shares and Dissenting Shares) shall be converted into Stock Consideration.

(b) Within five (5) business days after the Effective Time, Parent shall cause the Exchange Agent (as defined herein) to effect the allocation among the holders of Company

- 6 -

Shares (including holders of Company Electing Awards) of the rights to receive the Cash Consideration and the Stock Consideration as follows:

(i) if the aggregate number of Company Shares with respect to which Cash Elections shall have been made (which, for this purpose, shall be deemed to include the Dissenting Shares determined as of the Effective Time) (the “Total Cash Election Number”) exceeds the Cash Conversion Number, then (A) all Stock Election Shares and all Non-Election Shares shall be converted into the right to receive the Stock Consideration, and (B) Cash Election Shares of each holder thereof will be converted into the right to receive the Cash Consideration in respect of that number of Cash Election Shares equal to the product obtained by multiplying (x) the number of Cash Election Shares held by such holder by (y) a fraction, the numerator of which is the Cash Conversion Number and the denominator of which is the Total Cash Election Number (with the Exchange Agent to determine, consistent with Section 2.2(a), whether fractions of Cash Election Shares shall be rounded up or down), with the remaining number of such holder’s Cash Election Shares being converted into the right to receive the Stock Consideration; and

(ii) if the Total Cash Election Number is less than the Cash Conversion Number (the amount by which the Cash Conversion Number exceeds the Total Cash Election Number being referred to herein as the “Shortfall Number”), then all Cash Election Shares shall be converted into the right to receive the Cash Consideration, and the Stock Election Shares and Non-Election Shares shall be treated in the following manner:

(x) if the Shortfall Number is less than or equal to the number of Non-Election Shares, then all Stock Election Shares shall be converted into the right to receive the Stock Consideration, and the Non-Election Shares of each holder thereof shall convert into the right to receive the Cash Consideration in respect of that number of Non-Election Shares equal to the product obtained by multiplying (1) the number of Non-Election Shares held by such holder by (2) a fraction, the numerator of which is the Shortfall Number and the denominator of which is the total number of Non-Election Shares (with the Exchange Agent to determine, consistent with Section 2.2(a), whether fractions of Non-Election Shares shall be rounded up or down), with the remaining number of such holder’s Non-Election Shares being converted into the right to receive the Stock Consideration; or

(y) if the Shortfall Number exceeds the number of Non- Election Shares, then (1) all Non-Election Shares shall be converted into the right to receive the Cash Consideration and (2) all Stock Election Shares shall convert into the right to receive the Cash Consideration in respect of that number of Stock Election Shares equal to the product obtained by multiplying (A) the number of Stock Election Shares held by such holder by (B) a fraction, the numerator of which is the amount by which (1) the Shortfall Number exceeds (2) the total number of Non-Election Shares, and the denominator of which is the total number of Stock Election Shares (with the Exchange Agent to determine, consistent with Section 2.2(a), whether fractions of Stock Election Shares shall be rounded up or down), with the remaining number of

- 7 -

such holder’s Stock Election Shares being converted into the right to receive the Stock Consideration.

Section 2.3 Election Procedures.

(a) Elections. Each person who is a record holder of shares of Company Common Stock and/or who holds Company Electing Awards on the Election Form Record Date (as defined herein) shall have the right to submit an Election Form specifying (an “Election”) the number of Company Shares, if any, held by such person, whether directly or pursuant to any Company Electing Awards, in any case, that such person desires to have converted into the right to receive Stock Consideration (a “Stock Election”) and the number of such Company Shares that the holder desires to have converted into the right to receive Cash Consideration (a “Cash Election”). Holders of record of Company Shares who hold such Company Shares as nominees, trustees or in other representative capacities may submit a separate Election Form on or before the Election Deadline with respect to each beneficial owner for whom such nominee, trustee or representative holds such Company Shares.

(b) Appointment of Exchange Agent. Prior to mailing of the Election Form, 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.

(c) Mailing of Election Form; Election Deadline. Parent shall prepare and cause to be mailed a form of election, which form shall be subject to the reasonable approval of the Company (the “Election Form”), with the Proxy Statement/Prospectus to the record holders of Company Common Stock as of the record date for the Company Stockholders’ Meeting (the “Election Form Record Date”) and to each holder of Company Electing Awards as of such date, which Election Form shall be used by each such record holder of shares of Company Common Stock and each such holder of Company Electing Awards who wishes to make an Election. Any such holder’s Election shall have been properly made only if the Exchange Agent shall have received at its designated office, by 5:00 p.m., Eastern time, on a date prior to the Effective Time to be mutually agreed to by Parent and the Company and publicly disclosed (the “Election Deadline”), an Election Form properly completed and signed and accompanied (in the case of record holders of shares of Company Common Stock) by Certificates (unless such shares of Company Common Stock are Book-Entry Shares, in which case the holders shall follow the instructions set forth in the Election Form) of Company Common Stock to which such Election Form relates, duly endorsed in blank or otherwise in form acceptable for transfer on the books of the Company (or customary affidavits and indemnification regarding the loss or destruction of such Certificates or by an appropriate guarantee of delivery of such Certificates as set forth in such Election Form; provided that such Certificates are in fact delivered to the Exchange Agent within five (5) business days after the date of execution of such guarantee of delivery).

(d) Ability to Revoke Election Forms. Any stockholder or holder of Company Electing Awards may (i) change his Election by written notice received by the Exchange Agent prior to the Election Deadline, accompanied by a properly completed and signed revised Election Form or (ii) revoke his Election by written notice received by the Exchange Agent prior to the

- 8 -

Election Deadline or by withdrawal prior to the Election Deadline of his Certificates (if applicable), or of the guarantee of delivery of such Certificates (if applicable), previously deposited with the Exchange Agent. All Election Forms shall automatically be revoked if the Exchange Agent is notified in writing by Parent and the Company that the Merger has been abandoned and that this Agreement has been terminated. If an Election Form is revoked, the Certificate(s) (or guarantees of delivery, as appropriate), if any, for the Company Shares to which such Election Form relates shall be promptly returned to the stockholder submitting the same to the Exchange Agent.

(e) Determination of Exchange Agent Binding. Subject to the provisions of the Exchange Agent Agreement, the determination of the Exchange Agent shall be binding as to whether an Election shall have been properly made or revoked pursuant to this Section 2.3 with respect to Company Shares and when Elections and revocations were received by it. Subject to the provisions of the Exchange Agent Agreement, if the Exchange Agent determines that any Election was not properly made with respect to any Company Shares, such Company Shares shall be treated by the Exchange Agent as Non-Election Shares. Subject to the provisions of the Exchange Agent Agreement, the Exchange Agent also shall make all computations as to the allocation and the proration contemplated by Section 2.2, and absent manifest error any such computation shall be conclusive and binding on the holders of the Company Shares.

Section 2.4 Exchange of Certificates.

(a) Deposit of Merger Consideration. 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 Fractional Share Cash Amounts payable) at such time as is necessary for the payment to holders of Company Common Stock (including Company Common Stock subject to Company Electing Awards) and shall deposit, or shall cause to be deposited, with the Exchange Agent evidence of Parent Common Stock in book-entry form (and/or certificates representing such Parent Common Stock, at Parent’s election) representing the number of shares of Parent Common Stock sufficient to deliver the aggregate Stock 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 five (5) business days of the Closing Date, Parent shall cause the Exchange Agent to mail to each holder of record of Company Shares and each holder of Company Electing Awards whose Company Shares were converted pursuant to Section 2.1(a)(iii) or Section 2.5 (other than those holders who have properly completed and submitted, and have not revoked, Election Forms pursuant to Section 2.3) 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 (as applicable), 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 (as applicable) in exchange for the Merger Consideration, any Fractional Share Cash Amount and any dividends or other distributions to which such Certificates or Book-Entry Shares become entitled in accordance with Section 2.4(d).

- 9 -

No interest shall be paid or shall accrue on the cash payable upon surrender of any Certificate or Book-Entry Share or with respect to any Company Electing Awards and, until surrendered as contemplated by this Section 2.4, each Certificate and Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive, with respect to Certificates and Book-Entry Shares, upon such surrender, the Merger Consideration deliverable in respect of the shares represented by such Certificates or Book-Entry Shares pursuant to this Agreement, together with any Fractional Share Cash Amount and any dividends or other distributions to which such Certificates or Book-Entry Shares become entitled in accordance with Section 2.4(d).

(e) No Further Ownership Rights in Company Common Stock. The shares of Parent Common Stock delivered and cash paid in accordance with the terms of this Article II upon conversion of any Company Shares shall be deemed to have been delivered and paid in full satisfaction of all rights pertaining to such Company Shares. 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 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 2.4(b) (together with any Fractional Share Cash Amount and any dividends or other

(f) 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 and holders of Company Electing Awards 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.

(g) 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 180 days 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 Company (subject to abandoned property, escheat or other similar Laws), as general creditors thereof, for satisfaction of its claim for Merger Consideration and any dividends and distributions which such holder has the right to receive pursuant to this Article II without any interest thereon.

(h) 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.

(i) Withholding Rights. Each of the Surviving Company, 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 or any holder of any Company Stock Awards pursuant to this Agreement such amounts as may be required to

- 11 -

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.

(j) 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 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 Company with respect to such Certificate, the Exchange Agent (or, if subsequent to the termination of the Exchange Fund and subject to Section 2.4(g), Parent) shall deliver, in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration and any dividends and distributions deliverable in respect thereof pursuant to this Agreement.

(c) The execution and delivery by Parent and Merger Sub of this Agreement do not, and (assuming the Parent Approvals are obtained) the consummation of the transactions contemplated hereby and compliance with the provisions hereof will not (i) result in any loss, or suspension, limitation or impairment of any right of Parent or any of its Subsidiaries to own or use any assets required for the conduct of their business or result in any violation of, or default (with or without notice or lapse of time, or both) under, or give rise to a right of termination, cancellation, first offer, first refusal, modification or acceleration of any material obligation or to the loss of a benefit under any loan, guarantee of indebtedness or credit agreement, note, bond, mortgage, indenture, lease, agreement, contract (including, without limitation, any Mining Contract), instrument, permit, concession, franchise, right or license binding upon Parent or any of its Subsidiaries or by which or to which any of their respective properties, rights or assets are bound or subject, or result in the creation of any Liens other than Parent Permitted Liens, in each case, upon any of the properties or assets of Parent or any of its Subsidiaries, (ii) conflict with or result in any violation of any provision of the certificate of incorporation or bylaws or other equivalent organizational document, in each case as amended or restated, of Parent or any of its Subsidiaries or (iii) conflict with or violate any applicable Laws, except in the case of clauses (i) and (iii) for such losses, suspensions, limitations, impairments, conflicts, violations, defaults, terminations, cancellations, accelerations, or Liens as would not have, individually or in the aggregate, a Parent Material Adverse Effect.

As of their respective dates or, if amended, as of

- 38 -

the date of the last such amendment, the Parent SEC Documents complied in all material respects with the requirements of the Securities Act, the Exchange Act and the Sarbanes Oxley Act, as the case may be, and the applicable rules and regulations promulgated thereunder, and none of the Parent SEC Documents contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, except that information set forth in the Parent SEC Documents as of a later date (but before the date of this Agreement) will be deemed to modify information as of an earlier date.

(b) The consolidated financial statements (including all related notes and schedules) of Parent included in the Parent SEC Documents (i) fairly present in all material respects the consolidated financial position of Parent and its consolidated Subsidiaries, as at the respective dates thereof, and the consolidated results of their operations and their consolidated cash flows for the respective periods then ended, (ii) were prepared in conformity with GAAP (except, in the case of the unaudited statements, subject to normal year-end audit adjustments and the absence of footnote disclosure) applied on a consistent basis during the periods involved (except as may be indicated therein or in the notes thereto), (iii) have been prepared from, and are in accordance with, the books and records of Parent and its consolidated subsidiaries and (iv) comply in all material respects with the applicable accounting requirements and with the rules and regulations of the SEC, the Exchange Act and the Securities Act.

Parent has established and maintains disclosure controls and procedures and internal control over financial reporting (as such terms are defined in paragraphs (e) and (f), respectively, of Rule 13a-15 under the Exchange Act) as required by Rule 13a-15 under the Exchange Act. Parent’s disclosure controls and procedures are reasonably designed to ensure that all material information required to be disclosed by Parent in the reports that it files or furnishes under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that all such material information is accumulated and communicated to Parent’s management as appropriate to allow timely decisions regarding required disclosure and to make the certifications required pursuant to Sections 302 and 906 of the Sarbanes-Oxley Act. Parent’s

- 39 -

management has completed an assessment of the effectiveness of Parent’s internal control over financial reporting in compliance with the requirements of Section 404 of the Sarbanes-Oxley Act for the year ended December 31, 2011, and such assessment concluded that such controls were effective. Based on its most recent evaluation of internal controls over financial reporting prior to the date hereof, management of Parent has disclosed to Parent’s auditors and the audit committee of the Board of Directors of Parent (i) any significant deficiencies and material weaknesses in the design or operation of internal controls over financial reporting that are reasonably likely to adversely affect in any material respect Parent’s ability to report financial information and (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in Parent’s internal control over financial reporting, and each such deficiency, weakness and fraud so disclosed to auditors, if any, has been disclosed to the Company prior to the date hereof.

Section 4.6 Compliance with Law; Permits.

All Parent Permits are valid and in full force and effect and are not subject to any administrative or judicial proceeding that could result in modification, termination or revocation thereof, except where the failure to be in full force and effect or any modification, termination or revocation thereof would not have, individually or in the aggregate,

- 40 -

a Parent Material Adverse Effect. Parent and each of its Subsidiaries is in material compliance with the terms and requirements of all material Parent Permits.

(c) Since January 1, 2010, (i) none of Parent or any Subsidiary of Parent nor, to the knowledge of Parent, any director, officer, employee, auditor, accountant or representative of Parent or any Subsidiary of Parent, has received or otherwise had or obtained knowledge of any material complaint, allegation, assertion or claim, whether written or oral, regarding accounting, internal accounting controls or auditing practices, procedures, methodologies or methods of Parent or any Subsidiary of Parent or any material concerns from employees of Parent or any Subsidiary of Parent regarding questionable accounting or auditing matters with respect to Parent or any Subsidiary of Parent, and (ii) to the knowledge of Parent, no attorney representing Parent or any Subsidiary of Parent, whether or not employed by Parent or any Subsidiary of Parent, has reported evidence of a material violation of securities Laws, breach of fiduciary duty or similar violation by Parent, any Subsidiary of Parent or any of their respective officers, directors, employees or agents to the Board of Directors of Parent or any committee thereof, or to the General Counsel or Chief Executive Officer of Parent.

Section 5.2 Conduct of Business by Parent and Merger Sub.

(a) From and after the date hereof until the earlier of the Effective Time or Termination Date, and except (i) as may be required by applicable Law, (ii) with the prior written consent of the Company, (iii) as may be expressly contemplated or required by this Agreement or (iv) as set forth in Section 5.2(a) of the Parent Disclosure Schedule, Parent and Merger Sub covenant and agree that the business of Parent and its Subsidiaries shall be conducted in the ordinary course of business; provided, however, that no action by Parent or its Subsidiaries with respect to matters specifically addressed by any provision of Section 5.2(b) shall be deemed a breach of this sentence unless such action would constitute a breach of such other provision.

(b) Parent and Merger Sub agree with the Company, on behalf of themselves and Parent’s Subsidiaries, that from the date hereof and prior to the earlier of the Effective Time and the Termination Date, except (i) as may be required by applicable Law or the regulations or requirements of any stock exchange or regulatory organization applicable to Parent or any of its Subsidiaries, (ii) as may be consented to by the Company, (iii) as may be expressly contemplated or required by this Agreement, or (iv) as set forth in Section 5.2(b) of the Parent Disclosure Schedule, Parent and Merger Sub:

(A) except in each case as would not (after application of Section 2.1(c)) disproportionately adversely affect a holder of Company Common Stock relative to a holder of Parent Common Stock or delay or impede the Merger or the other transactions contemplated by this Agreement, adjust, reclassify, split, combine, subdivide or redeem, directly or indirectly, any shares of capital stock or other equity interest of Parent or securities convertible or exchangeable into or exercisable for any shares of capital stock or other equity interest of Parent;

(B) shall not adopt or implement a plan of complete or partial liquidation, dissolution, restructuring, recapitalization or other reorganization of Parent;

(D) shall not agree, in writing or otherwise, to take any of the foregoing actions that are prohibited pursuant to clauses (A) through (C) of this Section 5.2(b).

Section 5.3 Access.

(a) For purposes of furthering the transactions contemplated hereby, each party shall afford the other party and (i) the officers and employees and (ii) the accountants, consultants, legal counsel, financial advisors, financing sources (including the employees, consultants, and Representatives thereof) and agents and other representatives of such other party reasonable access during normal business hours, throughout the period prior to the earlier of the Effective Time and the Termination Date, to its and its Subsidiaries’ personnel and properties, contracts, commitments, books and records and any report, schedule or other document filed or

- 53 -

received by it pursuant to the requirements of applicable Laws and with such additional accounting, financing, operating, environmental and other data and information regarding such party as the other party may reasonably request. Notwithstanding the foregoing, neither party shall be required to afford such access if it would unreasonably disrupt the operations of such party or any of its Subsidiaries, would cause a violation of any agreement to which such party or any of its Subsidiaries is a party, would cause a risk of a loss of privilege to such party or any of its Subsidiaries or would constitute a violation of any applicable Law. Neither Parent nor any of its officers, employees or representatives, shall be permitted to perform any onsite procedures (including an onsite study or any invasive testing or sampling) with respect to any property of the Company or any of the Company’s Subsidiaries without the Company’s prior written consent.

(b) The parties hereto hereby agree that all information provided to them or their respective officers, directors, employees or representatives in connection with this Agreement and the consummation of the transactions contemplated hereby shall be governed in accordance with the confidentiality agreement, dated as of June 22, 2012, between the Company and Parent (the “Confidentiality Agreement”).

Section 5.4 No Solicitation.

(a) Except as expressly permitted by this Section 5.4, the Company shall, shall cause each of its affiliates and its and their respective officers, directors and employees to, and shall use reasonable best efforts to cause the agents, financial advisors, investment bankers, attorneys, accountants and other representatives (collectively “Representatives”) of the Company or any of its affiliates to: (A) immediately cease any ongoing solicitation, knowing encouragement, discussions or negotiations with any persons that may be ongoing with respect to a Company Takeover Proposal, and promptly instruct (to the extent it has contractual authority to do so and has not already done so prior to the date of this Agreement) or otherwise request, any person that has executed a confidentiality or non-disclosure agreement within the 36-month period prior to the date of this Agreement in connection with any actual or potential Company Takeover Proposal to return or destroy all such information or documents or material incorporating confidential information in the possession of such person or its Representatives and (B) until the Effective Time or, if earlier, the termination of this Agreement in accordance with Article VII, not, directly or indirectly, (1) solicit, initiate or knowingly facilitate or knowingly encourage (including by way of furnishing non-public information) any inquiries regarding, or the making of any proposal or offer that constitutes, or could reasonably be expected to lead to, a Company Takeover Proposal, (2) engage in, continue or otherwise participate in any discussions or negotiations regarding, or furnish to any other person any non-public information in connection with or for the purpose of encouraging or facilitating, a Company Takeover Proposal (other than, solely in response to an unsolicited inquiry, to refer the inquiring person to this Section 5.4 and to limit its conversation or other communication exclusively to such referral), or (3) approve, recommend or enter into, or propose to approve, recommend or enter into, any letter of intent or similar document, agreement, commitment, or agreement in principle (whether written or oral, binding or nonbinding) with respect to a Company Takeover Proposal. Except to the extent necessary to take any actions that the Company or any third party would otherwise be permitted to take pursuant to this Section 5.4 (and in such case only in accordance with the terms hereof), (A) the Company and its Subsidiaries shall not release any third party from, or waive, amend or modify any provision of,

- 54 -

or grant permission under, (1) any standstill provision in any agreement to which the Company or any of its Subsidiaries is a party or (2) any confidentiality provision in any agreement to which the Company or any of its Subsidiaries is a party other than, with respect to this clause (2), any waiver, amendment, modification or permission under a 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, enforce the confidentiality and standstill provisions of any such agreement, and the Company shall, and shall cause its Subsidiaries to, 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 5.4(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 5.4 and if the Company Board of 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. “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 (including standstill restrictions), provided that such confidentiality agreement shall not prohibit compliance by the Company with any of the provisions of this Section 5.4

(c) The Company shall promptly (and in no event later than 24 hours after receipt) notify, orally and in writing, Parent after receipt by the Company or any of its Representatives of any Company Takeover Proposal, including of the identity of the person making the Company Takeover Proposal and the material terms and conditions thereof, and shall promptly (and in no event later than 24 hours after receipt) provide copies to Parent of any written proposals, indications of interest, and/or draft agreements relating to such Company Takeover Proposal. 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

- 55 -

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 which prohibits the Company from providing any information to Parent in accordance with this Section 5.4.

(d) Except as expressly permitted by this Section 5.4(d) or by Section 5.4(e), the Company Board of Directors 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, in each case that includes a reaffirmation of the Company Recommendation) (it being understood that the Company Board of Directors 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 5.4(b)). Notwithstanding anything to the contrary set forth in this Agreement, prior to the time the Company Stockholder Approval is obtained, the Company Board of Directors may 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 5.4, the Company Board of 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 reasonably be likely to be inconsistent with the Company Board of Directors’ 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 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 of 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

- 56 -

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 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 5.4(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 5.4.

(e) Other than in connection with a Company Superior Proposal (which shall be subject to Section 5.4(d) and shall not be subject to this Section 5.4(e)), nothing in this Agreement shall prohibit or restrict the Company Board of Directors from making a Company Adverse Recommendation Change in response to an Intervening Event if the Company Board of Directors has determined in good faith, after consultation with its outside legal counsel, that the failure of the Company Board of Directors to make a Company Adverse Recommendation Change would reasonably be likely to be inconsistent with the Company Board of Directors’ 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 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, to the extent Parent wishes to negotiate, to enable Parent to propose revisions to the terms of this Agreement such that it would permit the Company Board of Directors not to make a Company Adverse Recommendation Change pursuant to this Section 5.4(e), and (C) following the end of such notice period, the Company Board of 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 Board of Directors’ fiduciary duties under applicable Law continue to require a Company Adverse Recommendation Change.

(f) Nothing contained in this Section 5.4 shall prohibit the Company or the Company Board of Directors 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 of Directors, after consultation with outside counsel, the failure so to disclose would reasonably be likely to be inconsistent with its fiduciary duties under applicable Law or obligations under applicable federal securities Law of the Company Board of Directors; 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 of Directors expressly and concurrently reaffirms the Company Recommendation.

Section 5.5 Filings; Other Actions.

(a) As promptly as reasonably practicable following the date of this Agreement, Parent and the Company shall prepare and file with the SEC the Form S-4, which will include the Proxy Statement/Prospectus. Each of Parent and the Company shall use reasonable best efforts to have the Form S-4 declared effective under the Securities Act as promptly as reasonably practicable after such filing and to keep the Form S-4 effective as long as necessary to consummate the Merger and the other transactions contemplated hereby. The Company will cause the Proxy Statement/Prospectus to be mailed to the Company’s stockholders as soon as reasonably practicable after the Form S-4 is declared effective under the Securities Act. Parent shall also take any action required to be taken under any applicable state or provincial securities laws in connection with the issuance and reservation of shares of Parent Common Stock in the Merger, and the Company shall furnish all information concerning the Company and the holders of Company Common Stock, or holders of a beneficial interest therein, as may be reasonably requested in connection with any such action. No filing of, or amendment or supplement to, the Form S-4 or the Proxy Statement/Prospectus will be made by Parent or the Company, as applicable, without the other’s prior consent (which shall not be unreasonably withheld, conditioned or delayed) and without providing the other party a reasonable opportunity to review and comment thereon. Parent or the Company, as applicable, will advise the other promptly after it receives oral or written notice of the time when the Form S-4 has become effective or any supplement or amendment thereto has been filed, the issuance of any stop order, the suspension of the qualification of the shares of Parent Common Stock issuable in connection with the Merger for offering or sale in any jurisdiction, or any oral or written request by the SEC for amendment of the Proxy Statement/Prospectus or the Form S-4 or comments thereon and responses thereto or requests by the SEC for additional information, and will promptly provide the other with copies of any written communication from the SEC or any state securities commission. If at any time prior to the Effective Time any information relating to Parent or the Company, or any of their respective affiliates, officers or directors, is discovered by Parent or the Company which should be set forth in an amendment or supplement to any of the Form S-4 or the Proxy Statement/Prospectus, so that any of such documents would not include a misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party that discovers such information shall promptly notify the other parties hereto and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by law, disseminated to the stockholders of the Company.

(b) As promptly as reasonably practicable following the clearance of the Proxy Statement by the SEC, 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 for the purpose of obtaining the Company Stockholder Approval (the “Company Stockholders’ Meeting”) and not postpone or adjourn the Company Stockholders’ Meeting except to the extent required by applicable Law 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; provided, that, unless otherwise agreed by the parties, the Company Stockholders’ Meeting may not be postponed or adjourned to a date that is more than 20 days after the date for which the Company Stockholders’ Meeting was originally scheduled (excluding any adjournments or postponements required by applicable

- 58 -

Law). The Company will, except in the case of a Company Adverse Recommendation Change, through its Board of Directors, recommend that its stockholders adopt this Agreement and will use reasonable best efforts to solicit from its stockholders proxies in favor of the adoption of this Agreement and to take all other action necessary or advisable to secure the vote or consent of its stockholders required by the rules of the NYSE or applicable Laws to obtain such approvals. The Company will not submit to the vote of its stockholders any Company Takeover Proposal other than the Merger.

Section 5.6 Employee Matters.

(a) Subject to applicable Law, until the first anniversary of the Effective Time, Parent shall and shall cause its Subsidiaries (including the Surviving Company) to provide to the employees of the Company and its Subsidiaries who are employees thereof as of the Effective Time (the “Company Employees”) compensation (including equity-based compensation) and benefit plans that are substantially comparable in the aggregate to those provided to the Company Employees immediately prior to the Effective Time.

(b) Effective as of the Effective Time and thereafter, Parent shall, or shall cause the Surviving Company to, cause any employee benefit plans sponsored or maintained by Parent or the Surviving Company or their Subsidiaries in which the Company Employees are eligible to participate (collectively, the “Post-Closing Plans”) to recognize the service of each Company Employee with the Company or its Subsidiaries (including any predecessor thereof) 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 purposes of determining an accrued benefit under any defined benefit retirement plan, (ii) apply for purposes of participation in any retiree welfare benefit plans, (iii) operate to duplicate any benefits of a Company Employee with respect to the same period of service, or (iv) 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 group health insurance benefits, to the extent that such Post-Closing Plan is made available to the Company Employees at or after the Effective Time, Parent shall use reasonable best efforts to, or shall cause the Surviving Company to, (A) cause any pre-existing condition limitations, eligibility waiting periods or similar provisions under such plan to be waived with respect to such Company Employee and his or her spouse and eligible dependents 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 and his or her spouse and eligible dependents for an amount equal to any eligible expenses incurred by such Company Employee in the year that includes the 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, co-payment 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. Such credited expenses shall also count

- 59 -

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 Company, 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 the Company’s 401(k) plans (the “Company 401(k) Plan”), effective as of the day prior to the Closing Date. Following the Effective Time and as soon as practicable following receipt of a favorable determination letter from the IRS on the termination of the Company 401(k) Plan, the assets thereof shall be distributed to the participants, and Parent shall, to the extent permitted by Parent’s 401(k) plan (the “Parent 401(k) Plan”), 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, inclusive of loans), in the form of cash, in an amount equal to the full account balance (including loans) distributed to such Company Employee from the Company 401(k) Plan to the Parent 401(k) Plan.

(e) From and after the Effective Time, Parent shall, or shall cause the Surviving Company to, honor all accrued and vested benefits and perform all obligations under each Company Benefit Plan, employment, deferred compensation, change in control, severance, termination or similar agreement that is currently in effect between the Company or any of its Subsidiaries and any current or former director, officer, employee, consultant, independent contractor or other service provider thereof 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 Company or any affiliate of Parent, or shall interfere with or restrict in any way the rights of Parent, the Surviving Company 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 Company, 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 Company or any of their Subsidiaries (including, after the Closing Date, Company and its Subsidiaries) or affiliates to amend, modify or terminate any particular Company Benefit Plan, employment agreement or any other benefit or employment plan, program, agreement or arrangement after the Closing Date. Notwithstanding any provision in this Agreement to the contrary, nothing in this Section 5.6 shall create any third-party beneficiary rights in any Company Employee or current or former

- 60 -

service provider of the Company or its affiliates (or any beneficiaries or dependents thereof).

Section 5.7 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 5.7. 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 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

- 61 -

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 5.7 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) Parent shall and, shall cause its Subsidiaries to, propose, negotiate, offer to commit and effect (and if such offer is accepted, commit to and effect), by consent decree, hold separate order, or otherwise, the sale, divestiture or disposition of such assets or businesses of Parent or any of its Subsidiaries, or effective as of the Effective Time, the Surviving Company or its Subsidiaries, or otherwise offer to take or offer to commit to take any action (including any action that limits its freedom of action, ownership or control with respect to, or its ability to retain or hold, any of the businesses, assets, product lines, properties or services of Parent, the Surviving Company, or any of their respective Subsidiaries) which it is lawfully capable of taking and if the offer is accepted, take or commit to take such action (each a “Divestiture Action”), in each case, as may be required in order to avoid the commencement of any Action to prohibit the Merger or any other transaction contemplated by this Agreement, or if already commenced, to avoid the entry of, or to effect the dissolution of, any injunction, temporary restraining order or other order in any Action so as to enable the Closing to occur as soon as reasonably possible (and in any event, not later than the End Date). To assist Parent in complying with its obligations set forth in this Section 5.7(c), 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 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. The Company shall not, without the written consent of Parent, publicly or before any Governmental Entity or other third party, offer, suggest, propose or negotiate, and shall not commit to or effect, by consent decree, hold separate order or otherwise, any Divestiture Action. Notwithstanding anything in this Agreement to the contrary, nothing in this Section 5.7 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 Parent Material Adverse Effect.

(d) 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 or as otherwise instructed by Parent, and counsel for both parties will closely cooperate during the entirety of any such Second Request review process.

- 62 -

(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 5.7.

Section 5.8 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.

For a period of six years from the Effective Time, Parent and the Surviving Company 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 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 Company’s organizational documents 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 exculpation, indemnification and advancement of expenses in respect of any

- 63 -

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) Parent and the Surviving Company shall, 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 Company shall cooperate with the Indemnified Party in the defense of any such Action.

If (i) the Company elects, with the prior written consent of Parent, or (ii) Parent elects, then the Company or Parent, as applicable, 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 Effective Time that were committed or alleged to have been committed by such Indemnified Parties in their capacity as such; provided that 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 5.10(c).

(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 5.10.

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 5.10 applies shall be third-party beneficiaries of this Section 5.10, and (ii) this Section 5.10 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 Company and their respective successors and assigns.

Section 5.11 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.

Section 5.12 Section 16 Matters. Prior to the Effective Time, Parent and the Company shall take all such steps as may be required to cause any dispositions of Company Common Stock (including derivative securities with respect to Company Common Stock) or acquisitions of shares of Parent Common Stock (including derivative securities with respect to Parent Common Stock) resulting from the transactions contemplated by this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company or will become subject to such reporting requirements with respect to Parent, to be exempt under Rule 16b-3 promulgated under the Exchange Act.

Section 5.13 Financing and Financing Cooperation.

(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 each such Commitment Letter may be amended, supplemented, modified and replaced as set forth below), (ii) satisfy on a timely basis all conditions applicable to Parent or Merger Sub to the funding of the Financing set forth in each Commitment Letter and within Parent’s or Merger Sub’s control (other than any condition where the failure to be so satisfied is a direct result of the Company’s failure to comply with clauses (d) and (e) of this Section 5.13) and otherwise comply with its obligations thereunder and (iii) negotiate and enter into definitive agreements with respect thereto on the terms and conditions contemplated by each Commitment Letter (including any “flex” provisions), or terms and conditions not materially less favorable

- 65 -

(taken as a whole) to Parent than the terms and conditions contemplated by the 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 to (subject to the terms and conditions thereof) add lenders, lead arrangers, bookrunners, syndication agents or similar entities who had not executed such Commitment Letter 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 Letters” (as modified to 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, as reasonably determined by Parent), 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 provide the Company with a copy of any new financing commitment (redacted for provisions related to fees, pricing, “flex” terms and any other economic terms) 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 provisions) for any reason, and such portion is required to fund the Cash Component, 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 (including the “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) to enable Parent to fund the payment of the Cash Component of the aggregate Merger Consideration. If an Alternative Financing is required in accordance with this Section 5.13(c), Parent shall provide the Company with a copy of any new financing commitment (redacted for provisions related to fees, pricing, “flex” terms and any other economic terms) 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.

- 66 -

(d) Prior to the Effective Time, the Company shall, and shall cause its Subsidiaries and their respective Representatives to, at Parent’s sole cost and expense, provide all cooperation that is 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 (and any predecessor independent accountant or independent accountants of BP Exploration & Production Inc. and BP America Production Company) 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 (providing “negative assurance” comfort) and drafts thereof to the underwriters, initial purchasers or placement agents, as applicable, in connection with 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 any Alternative Financing, including financial statements, financial data, pro forma financial statements, projections, 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 to consummate the offering(s) of debt securities contemplated by the Commitment Letters or as otherwise reasonably necessary in connection with the Financing or Alternative Financing and the Merger or to assist in receiving customary “comfort” (including “negative assurance” comfort) from independent accountants in connection with the offering(s) of debt securities contemplated by the Commitment Letters (provided that it is understood that assumptions underlying pro forma adjustments included in any pro forma financial statements or pro forma financial information related to the Merger or any related financing shall be the responsibility of Parent); (iii) 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 Financing or any Alternative Financing, at reasonable times and upon reasonable advance notice; (iv) 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) use commercially reasonable efforts to obtain the reasonable cooperation and assistance of counsel to the Company and its Subsidiaries in providing customary legal opinions (it being understood that the opinions related to the Financing or any Alternative Financing customarily provided by buyer’s counsel will be rendered by counsel to Parent); (vi) provide customary information, documents, authorization letters and certificates, enter into agreements (including supplemental indentures) and take other actions that are or may be customary in connection with the Financing or necessary, proper, advisable or desirable to permit Parent or any of its affiliates to fulfill conditions or obligations under the Commitment Letters and any other financing document (including all documentation and other information required by bank regulatory authorities under applicable “know-your-customer” and anti-money laundering rules and regulations); (vii) provide assistance in the preparation of one or more confidential information memoranda,

The Company will provide to Parent and the Financing Sources such information as may be necessary so that the marketing materials as they relate to the Company and its affiliates are complete and correct in all material respects.

(e) The Company shall use reasonable best efforts to (i) obtain customary payoff letters from third-party lenders and trustees with respect to the indebtedness of the Company and its Subsidiaries specified in Section 5.13(e) of the Company Disclosure Letter no later than ten business days prior to the Effective Time and (ii) deliver or cause to be delivered

- 68 -

such payoff letters to Parent promptly thereafter, and in any event no later than seven 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 5.13(e) 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 Encumbrances on assets relating to such terminated indebtedness.

(f) Notwithstanding anything in this Section 5.13 to the contrary, in fulfilling its obligations pursuant to this Section 5.13, (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 promptly upon request by the Company 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.

(g) Parent and Merger Sub acknowledge and agree that the obtaining of the Financing, or any Alternative Financing, is not a condition to Closing and reaffirm their obligation to consummate the transactions contemplated by this Agreement, on the terms and subject to the conditions set forth herein, irrespective and independently of the availability of the Financing or any Alternative Financing, subject to the fulfillment or waiver of the conditions set forth in Article VI. In addition, the completion of the issuance of senior notes (the “Senior Notes”) contemplated by the Commitment Letters is not a condition to Closing.

Section 5.14 Transaction Litigation. The Company shall give Parent the opportunity to participate 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.

In the event of termination of this Agreement pursuant to Section 7.1, this Agreement shall terminate (except for the provisions of Section 7.3 and Article VIII), and there shall be no other liability on the part of the Company or Parent to the other except as provided in Section 7.3 and liability arising out of or the result of, fraud or any willful or intentional breach of any covenant or agreement or willful or intentional breach of any representation or warranty in this Agreement occurring prior to termination or as provided for in the Confidentiality Agreement, in which case the aggrieved party shall be entitled to all rights and remedies available at law or in equity.

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)(i) as a result of a Company Adverse Recommendation Change due to an Intervening Event, the Company shall pay Parent up to $69,000,000 in respect of Parent’s expenses in connection with this Agreement (the “Expense 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)(i) as a result of a Company Adverse Recommendation Change due to a Company Superior Proposal or pursuant to Section 7.1(g)(ii), (ii) by the Company pursuant to Section 7.1(b) and, at the time of such termination, (A) the Company Stockholder Approval shall not have been obtained and (B) Parent would have been permitted to terminate this Agreement pursuant to Section 7.1(g)(i) as a result of a Company Adverse Recommendation Change due to a Company Superior Proposal or pursuant to Section 7.1(g)(ii), or (iii) by Parent or the Company pursuant to Section 7.1(b) or Section 7.1(d) or by Parent pursuant to Section 7.1(f), and in the case of any termination pursuant to this clause (iii), (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 or concurrently paid to Parent in respect of the Expense Reimbursement), by wire transfer (to an

- 74 -

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) prior to or concurrently with such termination, and in the case of clause (iii) the Expense Reimbursement within two business days of such termination and the Termination Fee (less any amounts previously or concurrently 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 $207,000,000. 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 or concurrently receives 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 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%.

(c) Solely for purposes of this Section 7.3, “Company Takeover Proposal” shall have the meaning ascribed thereto in Section 8.15(b)(xv), except that all references to 15% shall be changed to 50%.
