WHEREAS, the Board of Directors of each of the Company and Parent deem it advisable and in the best interests of their respective corporation and stockholders that the Company and Parent engage in a business combination; and

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth in this Agreement, and intending to be legally bound hereby, the parties agree as follows:

Upon the terms and subject to the conditions set forth in this Agreement, the closing of the Merger (the “Closing”) will take place at 10:00 a.m. New York City time on the date that is the fifth (5th) Business Day following the satisfaction or (subject to applicable Law) waiver of the conditions set forth in Article VII (excluding conditions that, by their nature, cannot be satisfied until the Closing Date, but subject to the fulfillment or waiver of those conditions); provided, however, that (i) in the event that the proceeds from the Financing (or any alternative financing) are unavailable on such fifth (5^th) Business Day, the Closing will take place on the earlier of (A) the date that is the tenth (10^th) Business Day following the date on which Parent receives the Election Notice from the Company and (B) December 31, 2009, and (ii) in no event shall Parent be obligated to consummate the Closing prior to July 31, 2009, unless this Agreement has been previously terminated pursuant to its terms or unless another time or date is agreed to in writing by the parties (the actual time and date of the Closing being referred to herein as the “Closing Date”). The Closing shall be held at the offices of Cadwalader, Xxxxxxxxxx & Xxxx LLP, Xxx Xxxxx Xxxxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx, 00000, or at such other place as the parties may agree.

Section 1.3 Effective Time. At the Closing, the Company shall (i) file a certificate of merger (the “Certificate of Merger”) in such form as is required by, and executed and acknowledged in accordance with, the relevant provisions of the DGCL and (ii) make all other filings or recordings required under the DGCL in connection with the Merger. The Merger shall become effective at such time as the Certificate of Merger is duly filed with the Delaware Secretary of State or at such subsequent time as Parent and the Company shall agree and as shall be specified in the Certificate of Merger (the date and time the Merger becomes effective being the “Effective Time”).

Section 1.4 Effects of the Merger. At and after the Effective Time, the Merger will have the effects set forth herein and in the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time all the property, rights, privileges, immunities, powers and franchises of the Company and Merger Sub shall be vested in the Surviving Corporation, and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation.

Section 1.5 Bylaws.

Section 1.6 Certificate of Incorporation. At the Effective Time, the certificate of incorporation of the Company shall be amended so as to read in its entirety as set forth in Exhibit B hereto and, as so amended, shall be the certificate of incorporation of the Surviving Corporation until thereafter amended in accordance with its terms and as provided by applicable Law (subject to Section 6.7).

Section 1.7 Officers and Directors. From and after the Effective Time, until their successors are duly elected or appointed and qualified in accordance with applicable Law, (i) the directors of Merger Sub immediately prior to the Effective Time shall be the directors of the Surviving Corporation and (ii) the officers of the Company immediately prior to the Effective Time shall be the officers of the Surviving Corporation.

Section 1.8 Effect on Capital Stock.

(a) At the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, each share of common stock, par value $0.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time, shall be converted into one validly issued, fully paid and non-assessable share of common stock, par value $0.01 per share, of the Surviving Corporation.

(b) At the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, each share of common stock, par value $0.33¹/3 per share, of the Company (“Company Common Stock”) issued and outstanding immediately prior to the Effective Time (other than Restricted Stock, which shall be treated in accordance with Section 1.9(d),

-2-

and shares of Company Common Stock and Company Convertible Preferred Stock owned directly or indirectly by Parent or held directly or indirectly by the Company, all of which shall be canceled as provided in Section 1.8(e)), shall, except as provided in Section 1.11 with respect to the shares of Company Common Stock as to which appraisal rights have been exercised, be converted into the right to receive (i) 0.985 (as may be adjusted pursuant to this Section 1.8, the “Exchange Ratio”) validly issued, fully paid and non-assessable shares of common stock (“Parent Common Stock”), par value $0.05 per share, of Parent (unless the aggregate number of shares of Parent Common Stock to be issued in the Merger pursuant to this Section 1.8 and Section 1.9, together with the shares, if any, of Parent Common Stock issuable upon conversion of the Parent Convertible Preferred Stock and the Floating Rate Convertible Senior Debentures Due 2024 (the “Convertible Debentures”), in each case to the extent shares of Parent Convertible Preferred Stock and/or the Convertible Debentures are issued and outstanding as of the Effective Time, would exceed 19.9% of Parent’s issued and outstanding shares of Parent Common Stock immediately prior to the Effective Time (19.9% of such issued and outstanding shares rounded down to the nearest whole share, the “Maximum Share Number”) in which case the Exchange Ratio shall be reduced (the amount of such reduction, the “Exchange Ratio Reduction Number”) to the minimum extent necessary such that the number of shares of Parent Common Stock issuable in the Merger pursuant to this Section 1.8 and Section 1.9, together with the shares, if any, of Parent Common Stock issuable upon conversion of the Parent Convertible Preferred Stock and the Convertible Debentures, equals the Maximum Share Number) (the “Stock Consideration”) and (ii) $33.00 in cash without interest plus, if the Exchange Ratio is adjusted pursuant to the preceding clause (i), the amount in cash equal to the Exchange Ratio Reduction Number multiplied by the Parent Share Cash Value (the “Cash Consideration”). Together with any cash in lieu of fractional shares of Parent Common Stock to be paid pursuant to Section 2.5, the Stock Consideration and Cash Consideration are collectively referred to herein as the “Common Stock Merger Consideration.”

(c) At the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, each share of the $2 Convertible Preferred Stock, par value $2.50 per share, of the Company (“Company Convertible Preferred Stock”), issued and outstanding immediately prior to the Effective Time, if any, shall be converted into the right to receive one share of a new series of convertible preferred stock (“Parent Convertible Preferred Stock”) to be issued by Parent at the Effective Time and to be designated as Parent Convertible Preferred Stock (the “Preferred Stock Merger Consideration”, and collectively with the Common Stock Merger Consideration, the “Merger Consideration”) having the same powers, designations, preferences and rights (to the fullest extent practicable) as the shares of Company Convertible Preferred Stock (it being understood that the number of shares of Parent Common Stock into which each share of Parent Convertible Preferred Stock shall be convertible will equal the product of (i) the number of shares of Common Stock into which a share of Company Convertible Preferred Stock is convertible immediately prior to the Effective Time and (ii) the sum of the (A) the Exchange Ratio and (B) the quotient of the Cash Consideration and the Parent Share Cash Value). Prior to the Closing, Parent shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Parent Common Stock for delivery upon conversion of the Parent Convertible Preferred Stock.

-3-

(d) Except as set forth in Section 1.8(e), Section 1.9(d) and Section 1.11, as a result of the Merger and without any action on the part of the holders thereof, at the Effective Time, all shares of outstanding Company Common Stock and Company Convertible Preferred Stock, if any, shall cease to be outstanding and shall be canceled and retired and shall cease to exist, and each holder of a certificate or certificates which immediately prior to the Effective Time represented any such shares of Company Common Stock (“Common Certificates”) or of Company Convertible Preferred Stock (“Preferred Certificates” and together with the Common Certificates, the “Certificates”) or book-entry shares which immediately prior to the Effective Time represented shares of Company Common Stock (“Common Book-Entry Shares”) or shares of Company Convertible Preferred Stock (“Preferred Book-Entry Shares” and together with the Common Book-Entry Shares, the “Book-Entry Shares”) shall thereafter cease to have any rights with respect to such shares of Company Common Stock or Company Convertible Preferred Stock, respectively, except as provided herein or by Law.

(e) Each share of Company Common Stock and Company Convertible Preferred Stock owned by Parent or held by the Company at the Effective Time including any Reacquired Shares shall, by virtue of the Merger, cease to be outstanding and shall be canceled and retired and no stock of Parent or other consideration shall be delivered in exchange therefor.

Section 1.9 Company Stock Options and Other Equity-Based Awards.

(a) By virtue of the Merger, each option to purchase shares of Company Common Stock under the applicable Company Stock Plans that is outstanding immediately prior to the Effective Time, whether or not then vested and exercisable (collectively, the “Options” or “Company Stock Options”) shall become fully vested and exercisable immediately prior to, and then shall be canceled at, the Effective Time, and the holder thereof shall, subject to Section 1.9(f), be entitled to receive an amount in cash equal to the product of (i) the excess, if any, of (1) the Per Share Amount over (2) the exercise price per share of Company Common Stock subject to such Option, with the aggregate amount of such payment rounded up to the nearest cent, and (ii) the total number of shares of Company Common Stock subject to such fully vested and exercisable Option as in effect immediately prior to the Effective Time (the “Option Consideration”). The Option Consideration shall be paid in a lump sum as soon as practicable after the Effective Time but in no event later than ten (10) Business Days following the Effective Time.

(b) By virtue of the Merger, each restricted stock unit, representing a right to receive one share of Company Common Stock (an “RSU”) granted by the Company under any Company Stock Plan, including each “performance share award” denominated in RSUs (but excluding any DSU (as defined in Section 1.9(c)), which is outstanding immediately prior to the Effective Time shall become fully vested (except that with respect to any RSU, which by the terms of the award agreement pursuant to which it was granted provides for a lesser percentage of such RSUs to become vested upon the consummation of the Merger, shall only become vested as to such lesser percentage), and then shall be canceled at the Effective Time, and the holder of such vested RSU shall, subject to Section 1.9(f), be entitled to receive an amount in cash equal to the Per Share Amount in respect of each share of Company Common Stock into which the vested portion of the RSU would otherwise be convertible (the “RSU Consideration”), which shall be paid in a lump sum as soon as practicable after the Effective Time but in no event later than ten (10) Business Days following the Effective Time. Notwithstanding the foregoing, any RSU that constitutes, either in whole or in part, a deferral of compensation subject to Section 409A of the

-4-

Code (the “409A Deferred RSUs”), shall be treated in the appropriate manner provided in (i) or (ii) below, as applicable:

(i) Xxxx 000X Xxxxxxxx XXX that first becomes vested as a result of the transactions contemplated under this Agreement (the “000X XXXx”) shall, as of the Effective Time, become a vested right to receive, in respect of each share of Company Common Stock into which the 000X XXXx would otherwise be convertible, the Common Stock Merger Consideration (the “000X XXX Consideration”); provided, however, that all such 000X XXX Consideration shall be deposited in a grantor trust that satisfies the requirements of Revenue Procedure 92-64 (the “Grantor Trust”) and that will serve as the funding source for the Surviving Corporation to satisfy its obligations to pay each former holder of a 409A Deferred RSU the amount of 000X XXX Consideration due to such holder at such time(s) and in such manner as may be provided under the terms of the applicable Company Stock Plan, award agreement, deferral election form and/or any other payment election form, applicable to such holder’s respective 000X XXX (collectively, the “Deferred Payment Terms”). Additionally, during the period that any such 000X XXX Consideration remains in such Grantor Trust, (x) the portion of the 000X XXX Consideration that is comprised of the Cash Consideration shall accrue interest at the “Market Rate” (as such term is defined under the Wyeth 2005 (409A) Deferred Compensation Plan (effective January 1, 2005) (the “Wyeth 2005 (409A) DCP”) and (y) the portion of the 000X XXX Consideration that is comprised of the Stock Consideration shall accrue, in additional shares of Parent Common Stock (with any cash dividends being reinvested into shares of Parent Common Stock).

(ii) In respect of (x) each 409A Deferred RSU that has first become vested in accordance with its terms, other than as a result of the transactions contemplated under this Agreement and (y) any RSU that would have constituted, either in whole or in part, a deferral of compensation subject to Section 409A of the Code, but for such RSU having been earned and vested prior to December 31, 2004 (and any dividend equivalents that have been credited with respect to such RSU) (any of the foregoing, a “Vested Deferred RSU”) for which there is outstanding a corresponding share of Company Common Stock held in the Wyeth Restricted Stock Trust (the “Stock Trust”) for the purpose of satisfying the Company’s obligations to deliver shares of Company Common Stock in respect of such Vested Deferred RSU (the “Deferred RSU Shares”) in accordance with the applicable Deferred Payment Terms, immediately upon the Effective Time, each such Deferred RSU Share shall be converted into Common Stock Merger Consideration pursuant to Section 1.8(b) above (the “Vested Deferred RSU Consideration”); provided, however, that all such Vested Deferred RSU Consideration shall be held in the Stock Trust and any payments due in respect of such Deferred RSU Shares shall be as set forth under the applicable Deferred Payment Terms; and provided, further, that, during the period that any such Vested Deferred RSU Consideration is held in the Stock Trust (x) the portion of the Vested Deferred RSU Consideration representing the Cash Consideration shall accrue interest at the Market Rate and (y) the portion of the Vested Deferred RSU Consideration representing the Stock Consideration shall accrue, in additional shares of Parent Common Stock, dividends in the same amount(s) and at the same time(s) as dividends are paid on Parent Common Stock.

-5-

(c) By virtue of the Merger and pursuant to the terms of the Company’s 2008 Non-Employee Director Stock Incentive Plan or 2006 Non-Employee Director Stock Incentive Plan (together, the “Director DSU Plans”), each deferred stock unit, representing a right to receive one share of Company Common Stock granted by the Company under the Director DSU Plans (a “DSU”) which is outstanding immediately prior to the Effective Time shall become vested and then canceled at the Effective Time, and the holder thereof shall, subject to Section 1.9(f), be entitled to receive (i) an amount in cash equal to the Per Share Amount in respect of each share of Company Common Stock subject to the DSU (including shares attributable to dividend equivalents accrued on such DSU and converted into additional shares of Company Common Stock subject to such DSU), and (ii) the amount in cash equal to any dividend equivalents then credited to the holder’s DSU account which have not yet been converted into shares of Company Common Stock, all in accordance with the Director DSU Plans (the “DSU Consideration”), which shall be paid in a lump sum as soon as practicable after the Effective Time but in no event later than ten (10) Business Days following the Effective Time. In addition, and pursuant to the terms of the Company’s Directors’ Deferral Plan (the “Director Deferral Plan”), effective as of the Effective Time, each phantom share of Common Stock credited to a participant’s account thereunder (including phantom shares attributable to dividend equivalents) shall be converted into the right to receive an amount in cash equal to the Per Share Amount (such amount, the “Director Deferral Amount”). Such Director Deferral Amounts shall, to the extent provided under the Director Deferral Plan, be paid out in a lump sum immediately following the Effective Time (but in no event later than ten (10) Business Days following the Effective Time); provided, however, that any such other Director Deferral Amounts (the “Grandfathered Amounts”) that do not, under the terms of the Director Deferral Plan, become payable immediately upon the Effective Time shall instead be paid out in accordance with the applicable payment schedules provided under the Director Deferral Plan; provided, further, that for so long as any Grandfathered Amounts remain in the accounts maintained under the Director Deferral Plan, such amounts shall accrue an amount of deemed interest at the “Company Credit” rate (as such term is defined in such plan).

(d) By virtue of the Merger and pursuant to the terms of the 1994 Restricted Stock Plan for Non-Employee Directors (the “1994 Plan”), each restricted share of Company Common Stock granted by the Company under the 1994 Plan that is either unvested, or vested but held in the Stock Trust (collectively, the “Restricted Stock”) that is outstanding immediately prior to the Effective Time shall, to the extent not vested, vest as of the Effective Time, and at the Effective Time, the holder of all of the foregoing Restricted Stock shall, subject to Section 1.9(f), be entitled to receive an amount in cash equal to the Per Share Amount in cancellation of each share of Restricted Stock previously held under such Company Stock Plan (the “Restricted Stock Consideration”). The Restricted Stock Consideration shall be paid to such holders as soon as practicable after the Effective Time but in no event later than ten (10) Business Days following the Effective Time.

(e) As of the Effective Time, each phantom share of Company Common Stock credited to a participant account under any of the Wyeth Supplemental Employee Savings Plan (amended and restated effective as of January 1, 2005), the Wyeth 2005 (409A) DCP and the Wyeth Deferred Compensation Plan, amended and restated as of November 20, 2003 (and further amended January 1, 2005) (collectively, the “Company Deferred Equity Unit Plans”) shall be converted into the right to receive an amount equal to the Common Stock Merger

-6-

Consideration (the “Deferred Equity Unit Amount” ); provided, further, however, that the Cash Consideration component of such Deferred Equity Unit Amount shall accrue interest at the Market Rate, unless and until all or any portion of such notional Cash Consideration component of the Deferred Equity Unit Amount is notionally invested in another investment option, to the extent provided for under any Deferred Equity Unit Plan, and the Stock Consideration component of such Deferred Equity Unit Amount shall earn dividend equivalents in the same manner as would otherwise be earned under the applicable Company Deferred Equity Unit Plan. All amounts payable under the Deferred Equity Unit Plans (including the Deferred Equity Unit Amount) shall be paid to participants in accordance with the terms of the applicable Deferred Payment Terms. Solely with respect to the Wyeth Management Incentive Plan, as amended through December 5, 2007 (the “MIP”), each right to receive a share of Company Common Stock outstanding thereunder as of the Effective Time shall be converted into the right to receive the Common Stock Merger Consideration, to be paid to participants therein in accordance with and subject to the terms of the MIP.

(f) All amounts payable pursuant to this Section 1.9 shall be reduced by any required withholding of taxes in accordance with Section 2.10 and shall, except as otherwise provided in this Section 1.9, be paid without interest.

(g) Any such amounts representing Option Consideration, RSU Consideration, 000X XXX Consideration, Vested Deferred RSU Consideration, DSU Consideration, Restricted Stock Consideration or the Director Deferred Amounts (and amounts due under the MIP) shall be paid by Parent or the Surviving Corporation, and any such amounts paid by the Surviving Corporation shall be reimbursed promptly by Parent to the Surviving Corporation following the Effective Time.

(h) Prior to the Effective Time, the Board of Directors of the Company (or the appropriate committee thereof) shall, and such Board of Directors (or the appropriate committee thereof) shall cause the Company to, use its commercially reasonable efforts to take all actions reasonably required to effectuate the provisions of this Section 1.9.

Section 1.10 Certain Adjustments. If, between the date of this Agreement and the Effective Time, the outstanding Parent Common Stock or Company Common Stock shall have been changed into a different number of shares or different class by reason of any reclassification, recapitalization, stock split, split-up, combination or exchange of shares or a stock dividend or dividend payable in any other securities shall be declared with a record date within such period, or any similar event shall have occurred, the Common Stock Merger Consideration shall be appropriately adjusted to provide to the holders of Company Common Stock the same economic effect as contemplated by this Agreement prior to such event.

Section 1.11 Appraisal Rights.

(a) Notwithstanding anything in this Agreement to the contrary, shares of Company Common Stock outstanding immediately prior to the Effective Time and held by a holder who has not voted in favor of the adoption of this Agreement and who has demanded appraisal for such shares of Company Common Stock in accordance with the DGCL shall not be converted into the right to receive the Common Stock Merger Consideration unless such holder

-7-

fails to perfect or withdraws or otherwise loses such holder’s right to appraisal in accordance with the DGCL. If, after the Effective Time, such holder fails to perfect or withdraws or loses such holder’s right to appraisal, such shares of Company Common Stock shall be treated as if they had been converted into, and exchanged for, as of the Effective Time, the right to receive the Common Stock Merger Consideration.

(b) The Company shall give Parent (i) prompt notice of any demands for appraisal received by the Company, withdrawals of such demands, and any other instruments served pursuant to Section 262 of the DGCL and received by the Company and (ii) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under the DGCL. The Company shall not, except with the prior written consent of Parent, make any payment with respect to any demands for appraisal or offer to settle or settle any such demands.

ARTICLE II

EXCHANGE OF SHARES

Section 2.1 Exchange Agent. Prior to the Effective Time, Parent shall appoint a commercial bank or trust company to act as exchange agent hereunder (which entity shall be reasonably acceptable to the Company) for the purpose of exchanging Certificates and Book-Entry Shares for the Merger Consideration (the “Exchange Agent”). At or prior to the Effective Time, Parent shall deposit with the Exchange Agent, (a) in trust for the benefit of holders of shares of Company Common Stock, Common Book-Entry Shares (or certificates if requested) representing the Parent Common Stock issuable, and cash in U.S. dollars in an amount sufficient to pay the Cash Consideration payable, pursuant to Section 1.8 in exchange for outstanding shares of Company Common Stock, and (b) in trust for the benefit of holders of shares of Company Convertible Preferred Stock, Preferred Book-Entry Shares (or certificates if requested) representing the Parent Convertible Preferred Stock issuable pursuant to Section 1.8 in exchange for outstanding shares of Company Convertible Preferred Stock. Parent agrees to make available directly or indirectly to the Exchange Agent from time to time as needed, any cash in lieu of fractional shares of Parent Common Stock to be issued or paid in consideration therefor pursuant to Section 2.5 of this Agreement and any dividends or distributions to which such holder is entitled pursuant to Section 2.3 of this Agreement. Any cash, shares of Parent Common Stock and Parent Convertible Preferred Stock deposited with the Exchange Agent shall hereinafter be referred to as the “Exchange Fund.” Notwithstanding anything herein to the contrary, the exchange procedures described in this Article II shall not apply to Restricted Stock and the Restricted Stock Consideration and the Exchange Agent shall not act as exchange agent for the Restricted Stock.

Section 2.2 Exchange Procedures.

(a) Promptly after the Effective Time, and in any event not later than the fifth (5^th) Business Day following the Effective Time, the Surviving Corporation shall cause the Exchange Agent to mail to each holder of record of a Certificate (i) a letter of transmittal which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent, and which letter shall be in

-8-

customary form and have such other provisions as Parent may reasonably specify (such letter to be reasonably acceptable to the Company prior to the Effective Time) and (ii) instructions for effecting the surrender of such Certificates (or effective affidavits of loss in lieu thereof) in exchange for the applicable Merger Consideration, any cash in lieu of fractional shares of Parent Common Stock to be issued or paid in consideration therefor pursuant to Section 2.5 of this Agreement and any dividends or distributions to which such holder is entitled pursuant to Section 2.3 of this Agreement.

Section 3.11 Employee Benefit Plans.

(a) Section 3.11(a) of the Company Disclosure Letter, sets forth a true, complete and correct list of each material “employee benefit plan” as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) (whether or not subject to ERISA), and any other material plan, policy, program practice, agreement, understanding or arrangement (whether written or oral) providing compensation or other benefits to any current or former director, officer, employee or consultant (or to any dependent or beneficiary thereof) of the Company or any ERISA Affiliate, which are now maintained, sponsored or contributed to by the Company or any ERISA Affiliate, or under which the Company or any ERISA Affiliate has any material obligation or liability, whether actual or contingent, including all incentive, bonus, deferred compensation, vacation, holiday, cafeteria, medical, disability, stock purchase, stock option, stock appreciation, phantom stock, restricted stock, restricted stock unit, stock-based compensation, change-in-control, retention, employment, consulting, personnel or severance policies, programs, practices, Contracts or arrangements (each, a “Company Benefit Plan”), excluding Foreign Benefit Plans. For purposes of this Agreement, the term “Foreign Benefit Plans” shall mean those Company Benefit Plans maintained, sponsored or contributed to primarily for the benefit of current or former employees of the Company or any ERISA Affiliate who are or were regularly employed outside the United States (but which shall exclude any such Company Benefit Plans to the extent required by

-21-

applicable foreign law to be so maintained, sponsored or contributed to). Not more than twenty (20) Business Days after the date hereof, the Company shall deliver a true, complete and correct list of each material Foreign Benefit Plan to Parent. For purposes of this Section 3.11, “ERISA Affiliate” shall mean any entity (whether or not incorporated) that, together with any other entity, is considered under common control and treated as one employer under Sections 414(b) or (c) of the Code. The Company has no express or implied commitment to terminate or modify or change any Company Benefit Plan in the United States, other than with respect to a termination, modification or change required by ERISA or the Code or which would not, individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect.

(b) With respect to each Company Benefit Plan (other than any Foreign Benefit Plan), the Company has made available to Parent (or, with respect to items (iv), (v), (vi) and (vii), will provide to Parent not more than twenty (20) Business Days after the date hereof) true, complete and correct copies of the following (as applicable): (i) the written document evidencing such Company Benefit Plan or, with respect to any such plan that is not in writing, a written description of the material terms thereof; (ii) the summary plan description; (iii) the most recent annual report, financial statement and/or actuarial report; (iv) the most recent determination letter from the Internal Revenue Service (the “IRS” ); (v) the most recent Form 5500 required to have been filed with the IRS, including all schedules thereto; (vi) any related trust agreements, insurance contracts or other funding arrangements; (vii) any notices to or from the IRS or any office or representative of the Department of Labor or Pension Benefit Guaranty Corporation (“PBGC”) relating to any unresolved compliance issues in respect of any such Company Benefit Plan; and (viii) all material amendments, modifications or supplements to any Company Benefit Plan. With respect to each Foreign Benefit Plan, the Company will provide to Parent not more than twenty (20) Business Days after the date hereof the items identified in each of clauses (i), (vi) and (viii) above.

(c) Except as would not, individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect, each Company Benefit Plan has been administered in accordance with its terms, applicable Law (including Section 409A of the Code) and any applicable collective bargaining agreement including timely filing of all Tax, annual reporting and other governmental filings required by ERISA and the Code and timely contribution (or, if not yet due, proper financial reporting) of any amounts required to be made under the terms of any of the Company Benefit Plans as of the date of this Agreement. With respect to each of the Company Benefit Plans, no event has occurred and there exists no condition or set of circumstances in connection with which the Company or any of its Subsidiaries would be subject to any liability that, individually or in the aggregate, would reasonably be expected to have a Company Material Adverse Effect. Each Company Benefit Plan that is intended to be “qualified” under Section 401 of the Code has received a favorable determination letter from the IRS to such effect and, to the Knowledge of the Company, no fact, circumstance or event has occurred or exists since the date of such determination letter that would reasonably be expected to adversely affect the qualified status of any such Company Benefit Plan. Except as would not, individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect, none of the Company or any of its Subsidiaries has received notice of and, to the Knowledge of the Company, there are no audits or investigations by any Governmental Entity with respect to, or other actions, claims, suits or other proceedings against or involving any Company Benefit Plan or asserting rights or claims to benefits under

-22-

any Company Benefit Plan (other than routine claims for benefits payable in the normal course). Other than as set forth on Section 3.11(c) of the Company Disclosure Letter, each Company Benefit Plan subject to ERISA that provides retiree healthcare or life insurance benefits in the United States provides by its terms that it may be amended or terminated without material liability to the Company or any of its Subsidiaries at any time after the Effective Time (other than as required by applicable Law).

(d) No Company Benefit Plan is a “multiemployer plan” (as defined in Sections 3(37) and 4001(a)(3) of ERISA) or a “multiple employer plan” within the meaning of Sections 4063/4064 of ERISA or Section 413(c) of the Code and neither the Company nor any ERISA Affiliate has sponsored or contributed to or been required to contribute to a “multiemployer plan” or “multiple employer plan.”

(e) Except as set forth on Section 3.11(e) of the Company Disclosure Letter, neither the Company nor any ERISA Affiliate maintains or contributes to, or during the six-year period prior to the date hereof has maintained or contributed to, any “employee benefit plan” within the meaning of Section 3(3) of ERISA that is subject to Section 412 of the Code or Section 302 or Title IV of ERISA. Except as would not have, individually or in the aggregate, a Company Material Adverse Effect, with respect to each plan set forth on Schedule 3.11(e) of the Company Disclosure Letter that is subject to Section 412 of the Code or Section 302 of Title IV of ERISA: (i) there does not exist any accumulated funding deficiency within the meaning of Section 412 of the Code or Section 302 of ERISA, whether or not waived; (ii) there has been no “reportable event” within the meaning of Section 4043 of ERISA and the regulations thereunder which required a notice to the PBGC which has not been fully and accurately reported in a timely fashion, as required, or which, whether or not reported, would constitute grounds for the PBGC to institute involuntary termination proceedings with respect to any Company Benefit Plan that is subject to Title IV of ERISA; (iii) all premiums to the PBGC have been timely paid in full; (iv) there has not been a partial termination; and (v) none of the following events has occurred: (A) the filing of a notice of intent to terminate, (B) the treatment of an amendment to such a Company Benefit Plan as a termination under Section 4041 of ERISA or (C) the commencement of proceedings by the PBGC to terminate such a Company Benefit Plan and, to the Knowledge of the Company, no condition exists that presents a substantial risk that such proceedings will be instituted or which would constitute grounds under Section 4042 of ERISA for the termination of, or the appointment of a trustee to administer, any such plan.

(f) Except as set forth on Section 3.11(f) of the Company Disclosure Letter, the execution of this Agreement or the consummation of the Merger will not constitute an event that, either alone or in conjunction with any other event, will or may result in (i) any payment, acceleration, termination, forgiveness of indebtedness, vesting, distribution, increase in compensation or benefits or obligation to fund benefits with respect to any current or former employee or other personnel of the Company or any of its Subsidiaries, (ii) any amount failing to be deductible by reason of Section 280G of the Code or (iii) the provision of any reimbursement of excise Taxes under Section 4999 of the Code or any income Taxes under the Code.

-23-

Governmental Entity; (ii) each Foreign Benefit Plan required to be registered has been registered and has been maintained in good standing with applicable regulatory authorities; and (iii) each Foreign Benefit Plan required to be funded and/or book reserved is funded and/or book reserved, as appropriate, in accordance with applicable Law.

Notwithstanding the foregoing, neither Parent nor any of its Subsidiaries shall be required to propose, negotiate, commit to or effect any such sale, divestiture or disposition of assets or business of Parent or the Company, or any of their respective Subsidiaries, or offer to take or offer to commit to take any such action where such action, sale, divestiture or disposition, individually or in the aggregate, would be of assets or a business of the Company or its Subsidiaries or Parent or any of its Subsidiaries, and such action,

-51-

sale, divestiture or disposition would result in the one year loss of net sales revenues (as measured by net 2008 sales revenue) in excess of $3,000,000,000. For purposes of calculating the loss of net sales revenue in the preceding sentence, the least amount of lost revenues (as measured by net 2008 sales revenue) as may be required 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, shall be used in the event that Parent elects to offer any action, sale, divestiture or disposition that would result in a higher loss of net sales revenue (as measured by net 2008 sales revenue) than reasonably required to achieve such result.

(e) Notwithstanding anything in this Agreement to the contrary, the Company shall not, without the 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 sale, divestiture, disposition, prohibition or limitation or other action of a type described in Section 6.3(d).

Section 6.4 Acquisition Proposals.

(a) The Company agrees that it shall not and shall cause its Subsidiaries not to, and shall use its reasonable best efforts to cause its and its Subsidiaries’ Representatives not to, directly or indirectly, (i) initiate, solicit or knowingly encourage any inquiries or the making of any proposal or offer from a Third Party relating to any Acquisition Proposal, (ii) enter into or participate in any substantive discussion or negotiation with respect to, or provide any confidential information or data to any Person relating to, an Acquisition Proposal, (iii) enter into any merger agreement, letter of intent, agreement in principle, share purchase agreement, asset purchase agreement, share exchange agreement, option agreement or other similar Contract relating to an Acquisition Proposal or enter into any Contract or agreement in principle requiring the Company to abandon, terminate or breach its obligations hereunder or fail to consummate the transactions contemplated hereby, (iv) take any action to make the provisions of any “fair price,” “moratorium,” “control share acquisition,” “business combination” or other similar anti-takeover statute or regulation (including any transaction under, or a Third Party becoming an “interested shareholder” under, Section 203 of the DGCL), or any restrictive provision of any applicable anti-takeover provision in the Company’s certificate of incorporation or bylaws, inapplicable to any transactions contemplated by an Acquisition Proposal (and, to the extent permitted thereunder, the Company shall promptly take all steps 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) or (v) resolve, propose or agree to do any of the foregoing. The Company shall immediately cease and cause to be terminated any solicitation, discussion or negotiation with any Persons conducted prior to the execution of this Agreement by the Company, its Subsidiaries or any of the Company’s Representatives with respect to any Acquisition Proposal and shall promptly request the return or destruction of all confidential information provided by or on behalf of the Company or any of its Subsidiaries to such Person in connection with the consideration of any Acquisition Proposal to the extent that the Company is entitled to have such documents returned or destroyed.

-52-

(b) Notwithstanding anything to the contrary contained in Section 6.4(a), if at any time following the date hereof and prior to the time on which the Company has received the Company Requisite Vote, (i) in response to an unsolicited Acquisition Proposal or any inquiry relating to a potential Acquisition Proposal made or received after the date of this Agreement from a Third Party whom the Company’s Board of Directors (or the Executive Committee thereof) determines, in good faith, is credible and is reasonably capable of making a Superior Proposal (an “Inquiry”), in each case, under circumstances not involving a breach of Section 6.4(a) in any material respect, the Company may furnish information with respect to the Company and its Subsidiaries to the Person making such Acquisition Proposal or Inquiry and (ii) participate in discussions or negotiations with the Person making such Acquisition Proposal or Inquiry; provided that the Company (A) will not, and will not allow the Company’s Subsidiaries and the Company’s Representatives to, disclose any information to such Person without first entering into a confidentiality agreement with terms overall no less favorable to the Company than those contained in the Confidentiality Agreement and (B) will, subject to applicable Law, promptly provide to Parent any information concerning the Company or its Subsidiaries provided to such other Person which was not previously provided to Parent.

(c) The Company shall promptly notify Parent in writing of any Acquisition Proposal or Inquiry (and in no event later than 24 hours following the Company’s, any of its Subsidiaries’ or any Representative’s receipt of the Acquisition Proposal or Inquiry), such notice to include the identity of the Person making such Acquisition Proposal or Inquiry and a copy of such Acquisition Proposal or Inquiry, including draft agreements or term sheets submitted in connection therewith (or, where no such copy is available, a reasonably detailed description of such Acquisition Proposal or Inquiry), including any modifications thereto. The Company shall keep Parent reasonably informed on a reasonably current basis of the status of any material developments with respect to an Acquisition Proposal or Inquiry and shall provide Parent with copies of all written inquiries and correspondence with respect to such Acquisition Proposal or Inquiry no later than 24 hours following the receipt thereof. The Company shall not, and shall cause the Company’s Subsidiaries not to, enter into any Contract with any Person subsequent to the date of this Agreement, and neither the Company nor any of its Subsidiaries is party to any Contract, in each case, that prohibits the Company from providing such information to Parent. The Company shall not, and shall cause the Company’s Subsidiaries not to, terminate, waive, amend or modify, or grant permission under, the standstill provisions of any agreement to which the Company or any of its Subsidiaries is a party which prohibits the counterparty from making, effecting, entering into, making or participating in any solicitation of proxies in respect of, seeking, proposing or otherwise acting alone or in concert with others, to influence the management or Board of the Directors of the Company with respect to, or advising, assisting, knowingly encouraging or acting as a financing source for, an Acquisition Proposal. The Company shall, and shall cause its Subsidiaries to, enforce the standstill provisions of any such agreement, and the Company shall, and shall cause its Subsidiaries to, immediately take all steps 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 except, in each case, if the Board of Directors concludes in good faith, after consultation with outside counsel, that the failure to take such action could reasonably be determined to be inconsistent with its fiduciary duties under applicable Law.

-53-

(d) Notwithstanding anything in this Agreement to the contrary, the Company’s Board of Directors may at any time prior to the time that the Company receives the Company Requisite Vote (i) effect a Change in the Company Recommendation in response to an Intervening Event if the Company’s Board of Directors concludes in good faith, after consultation with outside counsel, that the failure to take such action could reasonably be determined to be inconsistent with its fiduciary duties under applicable Law, (ii) effect a Change in the Company Recommendation in response to an Acquisition Proposal if the Company’s Board of Directors concludes in good faith, after consultation with outside counsel, that the failure to take such action could reasonably be determined to be inconsistent with its fiduciary duties under applicable Law, and/or (iii) if the Company receives an Acquisition Proposal which the Company’s Board of Directors concludes in good faith, after consultation with outside counsel and the Company’s financial advisors, constitutes a Superior Proposal, terminate this Agreement pursuant to Section 8.1(h) to enter into a definitive agreement with respect to such Superior Proposal (the “Alternative Acquisition Agreement”); provided, however, that the Company shall have provided prior written notice to Parent, at least three (3) Business Days in advance, of its intention to take any such action referred to in clause (i), (ii) and (iii).

(e) Nothing contained in this Section 6.4 shall prohibit the Company’s Board of Directors from (i) taking and disclosing to the stockholders of the Company a position contemplated by Rule 14e-2(a) promulgated under the Exchange Act or making a statement contemplated by Item 1012(a) of Regulation M-A or Rule 14d-9 promulgated under the Exchange Act or (ii) making any disclosure to the Company’s stockholders if the Board of Directors of the Company determined in good faith, after consultation with its outside counsel, that the failure to make such disclosure could reasonably be determined to be inconsistent with applicable Law; provided, however, that any disclosure of a position contemplated by Rule 14e-2(a) or Rule 14d-9 promulgated under the Exchange Act other than a “stop, look and listen” or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act, an express rejection of any applicable Acquisition Proposal or an express reaffirmation of its recommendation to its stockholders in favor of the Merger shall be deemed to be a Change of Board Recommendation.

For purposes of this Agreement, “Acquisition Proposal” means any offer or proposal by any Third Party concerning any (i) merger, consolidation, other business combination or similar transaction involving the Company or any of its Subsidiaries, pursuant to which such Person would own 15% or more of the consolidated assets, revenues or net income of the Company and its Subsidiaries, taken as a whole, (ii) sale, lease, license or other disposition directly or indirectly by merger, consolidation, business combination, share exchange, joint venture or otherwise, of assets of the Company (including Equity Interests of any of its Subsidiaries) or any Subsidiary of the Company representing 15% or more of the consolidated assets, revenues or net income of the Company and its Subsidiaries, taken as a whole, (iii) issuance or sale or other disposition (including by way of merger, consolidation, business combination, share exchange, joint venture or similar transaction) of Equity Interests representing 15% or more of the voting power of the Company, (iv) transaction or series of transactions in which any Person will acquire beneficial ownership or the right to acquire beneficial ownership of Equity Interests representing 15% or more of the voting power of the Company or (v) any combination of the foregoing.

-54-

For purposes of this Agreement, “Superior Proposal” shall mean a bona fide written Acquisition Proposal (except the references therein to “15%” shall be replaced by “50%”), which, in the good faith judgment of the Company’s Board of Directors (after consultation with the Company’s financial advisors and outside counsel), taking into account the various legal, financial and regulatory aspects of the proposal, including the financing terms thereof (it being understood that the inclusion of any “seller financing” in such Acquisition Proposal, pursuant to which the Company’s stockholders may be issued debt instruments as part of the consideration payable in connection with the transactions contemplated by such Acquisition Proposal, shall not create any inference that, nor be used by Parent to assert or otherwise claim that, an Acquisition Proposal is not a Superior Proposal), and the Person making such proposal (i) if accepted, is reasonably likely to be consummated, and (ii) if consummated would result in a transaction that is more favorable to the Company’s stockholders, from a financial point of view, than the Merger.

Section 6.5 Employee Benefits Matters.

(a) At the Effective Time, Parent shall provide employment to, or shall cause the Surviving Corporation to provide employment to, employees who were employed by the Company or its Subsidiaries as of the Effective Time (“Covered Employees”).

(b) From and after the Effective Time until the second anniversary of the Effective Time (the “Benefits Continuation Period”), Parent shall provide, or shall cause the Surviving Corporation to provide, to each Covered Employee: (i) the same annual base salary or wage rates in effect as of the date of this Agreement and the same annual incentive and bonus opportunities provided by the Company in respect of 2008 as set forth under the applicable Company Benefit Plan (and, for the avoidance of doubt, for purposes of annual cash bonus opportunities to be provided to Covered Employees whose annual cash bonuses in respect of 2008 were discretionary, the amount of such bonuses actually paid to such employees shall be deemed the amount of their “opportunity” for purposes of this provision), and (ii) employee benefits which are substantially comparable, in the aggregate, to those provided to similarly situated Covered Employees (as a group), in each case by the Company and its Subsidiaries immediately prior to the Effective Time; provided, however, that (A) the foregoing covenants shall not take into account any change in control- or transaction-based retention, transition, stay or similar bonus arrangements for purposes of defining either annual incentive and bonus opportunities or employee benefits as used in this Section 6.5(b)); (B) with respect to Covered Employees who are subject to collective bargaining agreements, compensation and benefits shall be provided in accordance with the applicable collective bargaining agreements; (C) so long as Parent shall, or shall cause the Surviving Corporation to, honor the provisions of Section 6.5(c) below with respect to a particular Covered Employee (other than any Covered Employee who participates in a Company Benefit Plan that is a Sales Force incentive or Integrated Metrics Reports Bonus Program), Parent shall be deemed to have satisfied the portion of the covenant contained in this Section 6.5(b) with respect to annual cash incentive or bonus opportunities to be provided to such Covered Employee in respect of 2009; (D) so long as Parent shall, or shall cause the Surviving Corporation to, honor the provisions of Section 6.5(d) or Section 6.5(g) (as it relates to the CIC Severance Agreements), as applicable to a given Covered Employee, Parent shall be deemed to have satisfied the portion of the covenant contained in this Section 6.5(b) with respect to any obligation to provide severance payments and/or benefits to any such

-55-

Covered Employee as may otherwise be required to be provided hereunder; and (E) with respect to any Covered Employees based outside the United States, Parent’s obligations under this Section 6.5(b) shall be modified to the extent necessary to comply with applicable Laws of the foreign countries and political subdivisions thereof in which such employees are based.

(c) Parent shall, or shall cause the Surviving Corporation to, and the Company shall, in each case honor all of the obligations and covenants relating to 2009 Bonuses (as defined on Section 5.1(r) of the Company Disclosure Letter) as are, and to the fullest extent, set forth in Section 6.5(c) of the Company Disclosure Letter.

(d) At all times during the Benefits Continuation Period, Parent shall, or shall cause the Surviving Corporation to, maintain the Company Special Transaction Severance Plan in accordance with its terms as in effect on the date hereof (as such plan is identified on Section 3.11(a) of the Company Disclosure Letter).

(e) At all times following the Effective Time, Parent shall, or shall cause the Surviving Corporation to, treat former employees of the Company or any of its Subsidiaries who, as of the Effective Time, are eligible to receive post-retirement health benefits under the applicable Company Benefit Plans, no less favorably than similarly situated former employees of the Parent with respect to post-retirement health benefits.

(f) With respect to any Parent Benefit Plans in which Covered Employees first become eligible to participate on or after the Effective Time (collectively, “New Benefit Plans”), Parent shall, or shall cause the Surviving Corporation to: (i) waive any pre-existing condition exclusions and waiting periods with respect to participation and coverage requirements applicable to Covered Employees under any such New Benefit Plans providing medical, dental or vision benefits to the same extent such limitation would have been waived or satisfied under the analogous Company Benefit Plan in which such Covered Employee participated immediately prior to the Effective Time, (ii) provide each Covered Employee with credit for any co-payments and deductibles paid prior to the Effective Time during the calendar year in which such Effective Time occurs (or if later, paid in the year in which such Covered Employee is first eligible to participate), to the same extent such credit was given under the analogous Company Benefit Plan prior to the Effective Time, in satisfying any applicable deductible or out-of-pocket requirements under any such New Benefit Plan in which the Covered Employee participates during the calendar year in which such Effective Time occurs (or if later, the year in which such Covered Employee is first eligible to participate) and (iii) recognize all service of each Covered Employee prior to the Effective Time to the Company, its Subsidiaries and any predecessor entities of the Company or any of its Subsidiaries (as well as service to Parent and its Affiliates (including the Surviving Corporation) after the Effective Time), for all purposes (including, but not limited to, eligibility to participate, vesting credit, entitlement to benefits and benefit accrual) of any New Benefit Plans (including those providing for vacation and paid time-off) in which any Covered Employee participates after the Effective Time; provided, however, that the foregoing shall not apply to the extent it would result in any duplication of benefits for the same period of service.

(g) From and after the Effective Time, Parent shall honor, fulfill and discharge, or shall cause the Surviving Corporation to honor, fulfill and discharge, in accordance with its respective terms as in effect as of the date hereof or as may be amended or terminated

-56-

after the date hereof with the prior written consent of Parent, each employment, change in control, severance and termination agreement between the Company or any of its Subsidiaries and any director, officer or employee of such company listed on Section 3.11(a) of the Company Disclosure Letter (the “CIC Severance Agreements”) and the obligations of Company and its Subsidiaries as of the Effective Time under each deferred compensation plan or agreement listed on Section 3.11(a) of the Company Disclosure Letter.

(h) Nothing in this Section 6.5 shall be construed to (i) limit the right of Parent or any of its Subsidiaries (including, following the Closing Date, the Surviving Corporation and its Subsidiaries) to amend or terminate any Company Benefit Plan or other employee benefit plan, to the extent such amendment or termination is permitted by the terms of the applicable plan, or (ii) require Parent or any of its Subsidiaries (including, following the Closing Date, the Surviving Corporation and its Subsidiaries) to retain the employment of any particular Covered Employee for any fixed period of time following the Closing Date.

(i) Without limiting the generality of Section 9.5, the provisions of this Section 6.5 are solely for the benefit of the parties to this Agreement, and no current or former employee, director or independent contractor or any other individual associated therewith shall be regarded for any purpose as a third-party beneficiary of the Agreement, and nothing herein shall be construed as an amendment to any Company Benefit Plan or other employee benefit plan for any purpose.

(j) Prior to the Effective Time, the Company shall reacquire from the Stock Trust any shares of Restricted Stock held by the Stock Trust (the “Excess Shares” and, upon their acquisition by the Company, the “Reacquired Shares”); provided, however, that the Company shall not reacquire such Excess Shares in exchange for payment of any consideration to the Stock Trust, unless such consideration shall be paid to such Stock Trust with express instructions to the trustee thereof to pay such consideration to the applicable beneficiaries of the consideration in respect of such Reacquired Shares in full satisfaction of the obligations of the Company under applicable Company Stock Plans in respect of such Reacquired Shares. From and after the date hereof until the Effective Time, the Company shall not cause the Stock Trust to sell or otherwise dispose of any Excess Shares except as permitted under this Section 6.5(j).

Section 6.6 Fees and Expenses. Subject to Section 6.13 and Section 8.2, whether or not the Merger is consummated, all Expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such Expenses, except if the Merger is consummated, the Surviving Corporation or its relevant Subsidiary shall pay, or cause to be paid, any and all property or transfer taxes imposed on the Company or its Subsidiaries.

Section 6.7 Directors’ and Officers’ Indemnification and Insurance.

(a) From and after the Effective Time, Parent shall, and shall cause the Surviving Corporation to, (i) indemnify, defend and hold harmless, all past and present directors, officers and employees of the Company and its Subsidiaries (in all of their capacities) and all fiduciaries under any Company Benefit Plans (collectively, the “Indemnified Parties”) against any costs, expenses (including attorney’s fees and expenses and disbursements), judgments,

-57-

fines, losses, claims damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to the fact that the Indemnified Party is or was a director, officer, employee or fiduciary of the Company or any of its Subsidiaries or a fiduciary under any Company Benefit Plan or is or was serving at the request of the Company or any of its Subsidiaries as a director, officer or employee of any other corporation, limited liability company, partnership, joint venture, trust or other business or non-profit enterprise (including an employee benefit plan) whether asserted or claimed prior to, at or after the Effective Time (including with respect to acts or omissions occurring in connection with this Agreement and the consummation of the transactions contemplated hereby), and provide advancement of expenses to the Indemnified Parties (within ten (10) days of receipt by Parent or the Surviving Corporation from an Indemnified Party of a request therefor), in all such cases to the same extent that such persons are indemnified or have the right to advancement of expenses as of the date of this Agreement by the Company pursuant to the Company’s certificate of incorporation, bylaws and indemnification agreements, if any, or by any one of the Company’s Subsidiaries pursuant to such Subsidiary’s certificate of incorporation, bylaws and indemnification agreements of any Subsidiary of the Company, if any, in existence on the date hereof, (ii) without limitation to clause (i), to the fullest extent permitted by applicable Law, include and cause to be maintained in effect in the Surviving Corporation’s (or any successor’s) certificate of incorporation and bylaws for a period of six (6) years after the Effective Time, the current provisions regarding elimination of liability of directors, and indemnification of and advancement of expenses to directors, officers and employees of the Company, contained in the certificate of incorporation and bylaws of the Company and (iii) not settle, compromise or consent to the entry of any judgment in any proceeding or threatened Action (and in which indemnification could be sought by an Indemnified Party hereunder), unless such settlement, compromise or consent includes an unconditional release of such Indemnified Party from all liability arising out of such Action or such Indemnified Party otherwise consents in writing, and cooperates in the defense of such proceeding or threatened Action. Prior to the Effective Time, the Company shall and, if the Company is unable to, Parent shall cause the Surviving Corporation to, obtain and fully pay for “tail” prepaid insurance policies with a claims period of at least six (6) years from and after the Effective Time from an insurance carrier with the same or better rating as the Company’s current insurance carrier with respect to directors’ and officers’ liability insurance and fiduciary insurance (collectively, “D&O Insurance”), for the Indemnified Parties, with terms, conditions, retentions and levels of coverage at least as favorable as the Company’s existing D&O Insurance with respect to matters existing or occurring prior to the Effective Time (including with respect to acts or omissions occurring in connection with this Agreement and the consummation of the transactions contemplated hereby). If such “tail” prepaid insurance policies have been obtained, Parent shall, and shall cause the Surviving Corporation after the Effective Time, to maintain such policies in full force and effect, for its full term, and to continue to honor its respective obligations thereunder. If the Company and the Surviving Corporation for any reason fail to obtain such “tail” prepaid insurance policies as of the Effective Time, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, continue to maintain in effect, at no expense to the beneficiaries, for a period of at least six (6) years from and after the Effective Time for the Indemnified Parties, the D&O Insurance (provided that Parent (or any successor) may substitute therefor policies of at least the same terms, conditions, retentions and levels of coverage and amounts which are, in the aggregate, as favorable to the Indemnified Parties as

-58-

provided in the existing policies as of the date of this Agreement) or, if such insurance is unavailable, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, purchase the best available D&O Insurance for such six-year period from an insurance carrier with the same or better credit rating as the Company’s current insurance carrier with respect to the Company’s existing D&O Insurance with terms, conditions, retentions and with levels of coverage at least as favorable as provided in the Company’s existing policies as of the date of this Agreement with respect to claims, actions, suits, proceedings or investigations, whether civil, criminal, administrative or investigative, arising out of or pertaining to facts or events that occurred prior to, at or after the Effective Time (including with respect to acts or omissions occurring in connection with this Agreement and the consummation of the transactions contemplated hereby), provided, however, that in no event will Parent or the Surviving Corporation be required to expend annually in excess of 300% of the annual premium currently paid by the Company for such coverage (and to the extent the annual premium would exceed 300% of the annual premium currently paid by the Company for such coverage, the Surviving Corporation shall use all reasonable efforts to cause to be maintained the maximum amount of coverage as is available for such 300% of such annual premium). The obligations of Parent and the Surviving Corporation under this Section 6.7 shall not be terminated, amended or modified in any manner so as to adversely affect any Indemnified Party (including their successors, heirs and legal representatives) to whom this Section 6.7 applies without the consent of such affected Indemnified Party (it being expressly agreed that the Indemnified Parties to whom this Section 6.7 applies shall be third party beneficiaries of this Section 6.7, and this Section 6.7 shall be enforceable by such Indemnified Parties and their respective successors, heirs and legal representatives and shall be binding on all successors and assigns of Parent and the Surviving Corporation).

(b) If Parent or any of its successors or assigns (i) shall consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) shall transfer all or substantially all of its properties and assets to any Person, then, and in each such case, proper provisions shall be made so that the successors and assigns of Parent shall assume all of the obligations set forth in this Section 6.7.

(c) The rights of the Indemnified Parties under this Section 6.7 shall be in addition to any rights such Indemnified Parties may have under the certificate of incorporation or bylaws of the Surviving Corporation or any of its Subsidiaries, or under any applicable Contracts or Laws, and Parent shall, and shall cause the Surviving Corporation to, honor and perform under all indemnification agreements entered into by the Company or any of its Subsidiaries.

Section 6.8 Public Announcements. Parent and the Company have agreed upon the form and substance of the press release to be issued by Parent, on the one hand, and the Company, on the other hand, announcing the execution of this Agreement and the Merger, which shall be issued promptly following the execution and delivery hereof. Subject to Section 6.1, each of Parent and the Company agrees that no public release, announcement, and/or other public statement with respect to the transactions contemplated hereby shall be issued prior to consulting with and considering in good faith the views of the other party, and except as such public release, announcement, and/or other public statement may be required by applicable Law or the rules or regulations of any applicable United States securities exchange or regulatory body

-59-

or Governmental Entity to which the relevant party is subject, in which case the party required to make the public release, announcement, and/or other public statement shall use its commercially reasonable efforts to allow each other party reasonable time to comment on such public release, announcement, and/or other public statement in advance of such issuance.

Section 6.9 Listing of Shares of Parent Common Stock and Parent Convertible Preferred Stock. Parent shall use its reasonable best efforts to cause the shares of Parent Common Stock and Parent Convertible Preferred Stock, if any, to be issued in the Merger and such other shares to be reserved for issuance in connection with the Merger to be approved for listing on the NYSE, subject to official notice of issuance, prior to the Effective Time.

Section 6.10 Dividends. After the date of this Agreement, each of Parent and the Company shall coordinate with the other the payment of dividends with respect to the Parent Common Stock and Company Common Stock and the record dates and payment dates relating thereto, it being the intention of the parties that holders of Parent Common Stock and Company Common Stock shall not receive two dividends, or fail to receive one dividend, for any single calendar quarter with respect to their shares of Parent Common Stock and/or Company Common Stock or any shares of Parent Common Stock that any such holder receives in exchange for such shares of Company Common Stock in the Merger. Notwithstanding anything herein to the contrary, until the earlier of the Effective Time and the termination of this Agreement in accordance with its terms, Parent agrees that it shall not declare, set aside, make or pay any quarterly cash dividend or distribution in excess of the amount contemplated in clause (iii) of Section 4.9 and the Company agrees that it shall not declare, set aside, make or pay any quarterly cash dividend or distribution in excess of the amount contemplated in clause (j) of Section 5.1.

Section 6.11 Section 16 Matters. Prior to the Effective Time, each of 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 Parent Common Stock resulting from the transactions contemplated hereby by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company, to be exempt under Rule 16b-3 promulgated under the Exchange Act, such steps to be taken in accordance with the interpretive guidance set forth by the SEC.

Section 6.12 Company Cooperation on Certain Matters. After the date hereof and prior to the Effective Time, Parent and the Company shall establish a mechanism, subject to applicable Law, reasonably acceptable to both parties by which the parties will confer on a regular and continued basis regarding the general status of the ongoing operations of the Company and its Subsidiaries and integration planning matters and communicate and consult with specific persons to be identified by each party to the other with respect to the foregoing.

Section 6.13 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, proper or advisable to consummate and obtain the Financing on the terms and conditions described in the Commitment Letter, including using reasonable best efforts to (i) maintain in effect the Commitment Letter, (ii)

-60-

negotiate definitive agreements with respect thereto on terms and conditions (including the “flex” provisions) contemplated by the Commitment Letter and execute and deliver to the Company a copy thereof concurrently with such execution, (iii) satisfy on a timely basis all conditions applicable to Parent in the Commitment Letter that are within its control and comply with its obligations thereunder, (iv) provide prior to the Effective Time the lenders under the Commitment Letter with such evidence as may be requested by such lenders to demonstrate the satisfaction of the condition set forth in Paragraph 2 of Annex D to the Commitment Letter, including if necessary by requesting that Xxxxx’x Investors Services, Inc. and Standard & Poor’s provide written evidence thereof at the Closing and (v) enforce its rights under the Commitment Letter in the event of a breach by the financing sources that impedes or delays Closing, including seeking specific performance of the parties thereunder. In the event that all conditions to the Commitment Letter have been satisfied or, upon funding will be satisfied, Parent and Merger Sub shall use their reasonable best efforts to cause the lenders and the other Persons providing such Financing to fund on the Closing Date the Financing required to consummate the Merger and the other transactions contemplated by this Agreement (including by taking enforcement action, including seeking specific performance, to cause such lenders and the other Persons providing such Financing to fund such Financing). Parent shall have the right from time to time to amend, replace, supplement or otherwise modify, or waive any of its rights under, the Commitment Letter and/or substitute other debt or equity financing for all or any portion of the Financing from the same and/or alternative financing sources, provided that any such amendment, replacement, supplement or other modification to or waiver of any provision of the Commitment Letter that amends the Financing and/or substitution of all or any portion of the Financing shall not (A) expand upon the conditions precedent or contingencies to the Financing as set forth in the Commitment Letter or (B) prevent or impede or delay the consummation of the Merger and the other transactions contemplated by this Agreement. Parent shall be permitted to reduce the amount of Financing under the Commitment Letter in its reasonable discretion, provided, that Parent shall not reduce the Financing to an amount committed below the amount that is required, together with the financial resources of Parent and Merger Sub, including cash on hand and marketable securities, to consummate the Merger, and provided further that such reduction shall not (A) expand upon the conditions precedent or contingencies to the Financing as set forth in the Commitment Letter or (B) prevent or impede or delay the consummation of the Merger and the other transactions contemplated by this Agreement. If any portion of the Financing becomes unavailable or Parent becomes aware of any event or circumstance that makes any portion of the Financing unavailable, in each case, on the terms and conditions (including the “flex” provisions) contemplated in the Commitment Letter and such portion is reasonably required to fund the Merger Consideration, Parent shall use its reasonable best efforts to arrange and obtain alternative financing from alternative financial institutions in an amount sufficient to consummate the transactions contemplated by this Agreement upon conditions no less favorable to Parent and the Company than those in the Commitment Letter as promptly as practicable following the occurrence of such event. Parent shall give the Company prompt oral and written notice (but in any event not later than 48 hours after the occurrence) of any material breach by any party to the Commitment Letter or of any condition not likely to be satisfied, in each case, of which Parent becomes aware or any termination of the Commitment Letter. Parent shall keep the Company informed on a reasonably current basis of the status of its efforts to arrange the Financing.

Section 9.4 Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other party, it being understood that each party need not sign the same counterpart.

Section 9.5 Entire Agreement; No Third-Party Beneficiaries.

(a) This Agreement (including the Exhibits and Schedules hereto) and the Confidentiality Agreement constitute the entire agreement, and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof and thereof.

(b) This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement, other than Section 6.7 (which is intended to be for the benefit of the Persons covered thereby and may be enforced by such Persons).

Section 9.6 Governing Law. This Agreement shall be governed and construed in accordance with the laws of the State of Delaware (without giving effect to choice of law principles thereof).

Section 9.7 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Notwithstanding the foregoing, upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

Section 9.8 Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties, in whole or in part (whether by operation of Law or otherwise), without the prior written consent of the other party, and any attempt to make any such assignment without such consent shall be null and void, except that Merger Sub may assign, in its sole discretion, any or all of its rights, interests and obligations under this Agreement to any direct wholly-owned Subsidiary of Parent without the consent of the Company, but no such assignment shall relieve Merger Sub of any of its obligations under this Agreement. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns.

Section 9.9 Submission to Jurisdiction; Waivers. Each of the parties irrevocably agrees that any legal action or proceeding with respect to this Agreement or for recognition and enforcement of any judgment in respect hereof brought by any other party hereto or its successors or assigns may be brought and determined exclusively in the Court of Chancery

-74-

of the State of Delaware or, if under applicable Law exclusive jurisdiction over such matter is vested in the federal courts, any court of the United States located in the State of Delaware, and each of the parties to this Agreement hereby irrevocably submits with regard to any such action or proceeding for itself and in respect to its property, generally and unconditionally, to the exclusive jurisdiction of the aforesaid courts and agrees that it will not bring any legal action or proceeding with respect to this Agreement or for recognition and enforcement of any judgment in respect hereof in any court other than the aforesaid courts. Each of the parties to this Agreement hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement or for recognition and enforcement of any judgment in respect hereof, (i) any claim that it is not personally subject to the jurisdiction of the above-named courts for any reason other than the failure to lawfully serve process, (ii) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise), and (iii) to the fullest extent permitted by applicable Law, that (A) the suit, action or proceeding in any such court is brought in an inconvenient forum, (B) the venue of such suit, action or proceeding is improper and (C) this Agreement, or the subject matter hereof, may not be enforced in or by such courts. Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.2; provided that nothing in this Agreement shall affect the right of any party to this Agreement to serve process in any other manner permitted by law.

EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (II) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (III) EACH PARTY MAKES THIS WAIVER VOLUNTARILY AND (IV) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.11.
