WHEREAS, (i) concurrently with the execution of this Agreement, Parent, Dr. Patrick Soon-Shiong will execute and deliver a Noncompetition and Confidentiality Agreement in substantially the form attached hereto as Exhibit A (the “Noncompetition and Confidentiality Agreement”), which will become effective at the Effective Time (as hereinafter defined), and (ii) as of or prior to the Closing, Parent and a trustee mutually agreeable to Parent and the Company (the “Trustee”) will enter into a Contingent Value Rights Agreement in substantially the form attached hereto as Exhibit B (the “CVR Agreement” and, together with the Noncompetition and Confidentiality Agreement and the Voting Agreement, the “Related Agreements”); and

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

ARTICLE I

THE MERGER

Section 1.1 The Merger. Upon the terms and subject to the conditions hereof, and in accordance with the General Corporation Law of the State of Delaware (the “DGCL”), at the Effective Time, Sub shall be merged with and into the Company and the separate existence of Sub shall thereupon cease, and the Company, as the corporation surviving the Merger (the “Surviving Corporation”), shall by virtue of the Merger continue its corporate existence under the laws of the State of Delaware.

Section 1.2 Effective Time of the Merger. The Merger shall become effective at the date and time (the “Effective Time”) when the certificate of merger (the “Certificate of Merger”) shall have been duly executed and filed with the Secretary of State of the State of Delaware in accordance with the DGCL, or at such other time as is specified in the Certificate of Merger in accordance with the DGCL, which Certificate of Merger shall be filed on the Closing Date as soon as practicable following the Closing.

Section 1.3 Certificate of Incorporation. Subject to Section 6.2(a), at the Effective Time, the amended and restated certificate of incorporation of the Company (the “Certificate of Incorporation”) shall, by virtue of the Merger, be amended and restated in a form mutually agreed and, as so amended, shall be the certificate of incorporation of the Surviving Corporation, until thereafter changed or amended in accordance with its terms and as provided by Law and this Agreement.

Section 1.4 By-laws. Subject to Section 6.2(a), at the Effective Time, the by-laws of Sub in effect immediately prior to the Effective Time shall be the by-laws of the Surviving Corporation, except that all references to Sub therein shall be automatically amended and replaced with references to the Surviving Corporation, until thereafter changed or amended in accordance with their terms and as provided by Law and this Agreement.

Section 1.5 Board of Directors and Officers. The directors of Sub and the officers of the Company in office immediately prior to the Effective Time shall, from and after the Effective Time, be the directors and officers, respectively, of the Surviving Corporation, in each case until their respective successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal, in accordance with the Surviving Corporation’s Certificate of Incorporation and by-laws.

Section 1.6 Effects of Merger. The Merger shall have the effects set forth in the DGCL.

ARTICLE II

CONVERSION OF SHARES

Section 2.1 Conversion of Shares.

(a) Conversion of Shares. As of the Effective Time, by virtue of the Merger and without any action on the part of Parent, Sub, the Company or any holders of shares of capital stock of the Company:

(i) Each outstanding share of common stock, par value $0.001 per share, of the Company (the “Company Common Stock”) that is held in the treasury of the Company and any shares of Company Common Stock owned by Parent, Sub or any wholly owned subsidiary of Parent or the Company shall be canceled and no consideration shall be delivered in exchange therefor (such shares, the “Excluded Company Shares”).

(ii) Subject to Section 2.3, each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than Excluded Company Shares) shall be converted into the right to receive from Parent (1) an amount in cash, without interest, equal to $58.00 (the “Cash Consideration”), (2) 0. 2617 (the “Exchange Ratio”) of a share of common stock, par value $.01 per share (the “Parent Common Stock”), of Parent (the “Stock Consideration”), and (3) one contingent value right (a “CVR”) issued by Parent subject to and in accordance with the CVR Agreement (the consideration contemplated by subclauses (1), (2) and (3) together, the “Merger Consideration”). Each CVR issued as Merger Consideration hereunder will be substantially in the form attached as Annex A to the CVR Agreement (the “CVR Certificate”).

All such shares of Company Common Stock, when so converted, shall no longer be outstanding and shall automatically be canceled and retired, and each holder of a certificate or certificates (the “Certificates”) representing any such shares of Company Common Stock, and each holder of non-certificated shares of Company Common Stock represented by book-entry on the records of the Company or the Company’s transfer agent (“Book-Entry Shares”), shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration, any cash in lieu of fractional shares payable pursuant to Section 2.2(e) and any dividends or other distributions to which such holder is entitled pursuant to Section 2.2(d), without interest.

(b) Each share of common stock of Sub issued and outstanding immediately prior to the Effective Time shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into and become at the Effective Time one validly issued, fully paid and nonassessable share of common stock, par value $0.001 per share, of the Surviving Corporation.

Section 2.2 Payment and Exchange of Certificates.

(a) Prior to the mailing of the proxy statement/prospectus to be included in the registration statement on Form S-4 to be filed by Parent with the SEC (as defined in Section 3.4(a)) to register the shares of Parent Common Stock and CVRs to be issued in connection with the Merger (such proxy statement/prospectus, together with any amendments or supplements thereto, the “Proxy Statement/Prospectus”, and such registration statement, together with any amendments, supplements and exhibits thereto, the “Registration Statement”), Parent shall appoint a commercial bank or trust company reasonably acceptable to the Company to act as paying agent hereunder (the “Paying Agent”) for the purpose of payment of the aggregate Merger Consideration to be paid and delivered to Securityholders (as defined in Section 2.2(b)) under this ARTICLE II. Parent will enter into a paying agent agreement in form and substance reasonably acceptable to the Company at least two Business Days prior to the mailing of the Proxy Statement/Prospectus to the stockholders of the Company. As used herein, “Business Day” means any day of the year on which national banking institutions in New York are open to the public for conducting business and are not required or authorized to close.

(b) At the Closing, Parent shall deposit, or cause to be deposited, with the Paying Agent (i) cash in an amount sufficient to pay the aggregate Cash Consideration (ii) certificates representing a number of shares of Parent Common Stock equal to the Exchange Ratio multiplied by the number of outstanding shares of Company Common Stock held by holders (collectively, the “Securityholders”) of all shares of Company Common Stock (other than Excluded Company Shares and Dissenting Company Shares), and (iii) CVR Certificates representing the aggregate number of CVRs issuable pursuant to the CVR Agreement in accordance with Section 2.1(a)(ii) to which the Securityholders will become entitled under this ARTICLE II at the Effective Time. Parent further agrees to deposit, or cause to be deposited, with the Paying Agent, from time to time as needed, immediately available funds sufficient to pay cash in lieu of fractional shares pursuant to Section 2.2(e) and any dividends and other distributions pursuant to Section 2.2(d). The aggregate amount of such Cash Consideration and other cash amounts, certificates representing shares of Parent Common Stock and CVRs deposited with the Paying Agent is referred to herein as the “Exchange Fund.” The Paying Agent shall cause the Exchange Fund to be (1) held for the benefit of the Securityholders and (2) promptly applied to making the payments and deliveries provided for in this ARTICLE II. The Exchange Fund shall not be used for any purpose that is not provided for herein. The Paying Agent shall invest any cash included in the Exchange Fund as directed by Parent, in direct obligations of the United States of America or obligations for which the full faith and credit of the United States of America is pledged to provide for the payment of all principal and interest, or a combination thereof. Any interest and other income resulting from such investments shall be kept in the Exchange Fund. To the extent that there are losses with respect to such investments, or the Exchange Fund diminishes for other reasons below the level required to make prompt payments of the aggregate cash consideration to be paid to Securityholders as contemplated hereby, Parent shall promptly replace or restore the portion of the Exchange Fund lost through investments or other events so as to ensure that the Exchange Fund is, at all times, maintained at a level sufficient to make such payments. Any portion of the Exchange Fund (including the proceeds of any interest and other income received by the Paying Agent in respect of such funds) that remains undistributed to the Securityholders one year after the Effective Time of the Merger shall be delivered to Parent at such time. Thereafter, Securityholders shall look only to Parent (subject to the terms of this Agreement and to abandoned property, escheat or other similar Laws) as a general creditor for payment of the consideration payable to them under this ARTICLE II, without interest, upon the surrender of any Certificates held by them. Notwithstanding any provision of this Agreement to the contrary, none of the Paying Agent, Parent, the Surviving Corporation or any other party hereto shall be liable to any Person for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or other similar Law.

(c) As soon as practicable (but in any event within two Business Days) after the Effective Time, Parent shall cause the Paying Agent to mail to each holder of record of shares of Company Common Stock represented by Certificates and to each holder of Book-Entry Shares, other than Excluded Company Shares and Dissenting Company Shares: (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates or Book-Entry Shares shall pass, only upon actual delivery of the Certificates or transfer of Book-Entry Shares, as the case may be, to the Paying Agent and shall be in a form reasonably agreed upon by Parent and the Company prior to the Closing); and (ii) instructions for use in effecting the surrender of the Certificates or transfer of Book-Entry Shares, as the case may be, in exchange for the Merger Consideration. Upon surrender of a Certificate (or delivery of such customary affidavits and indemnities with respect to a lost Certificate which the Paying Agent and/or the Company’s transfer agent may reasonably require) or transfer of Book-Entry Shares for cancellation to the Paying Agent, together with such letter of transmittal duly executed and in proper form, and such other documents as may reasonably be required by the Paying Agent, the holder of such Certificate or Book-Entry Shares shall be entitled to receive in exchange therefor the Merger Consideration into which the shares of Company Common Stock theretofore represented by such Certificate or Book-Entry Shares shall have been converted pursuant to Section 2.1, any cash in lieu of fractional shares payable pursuant to Section 2.2(e) and any dividends or other distributions to which such holder is entitled pursuant to Section 2.2(d), and the Certificates so surrendered or Book-Entry Shares so transferred shall forthwith be canceled. No interest will be paid or will accrue on the Merger Consideration, cash in lieu of fractional shares payable pursuant to Section 2.2(e) or dividends or other distributions to which such holder is entitled pursuant to Section 2.2(d), payable upon the surrender of any Certificate or transfer of Book-Entry Shares. In the event of a transfer of ownership of Company Common Stock that is not registered in the transfer records of the Company, payment may be made to a Person other than the Person in whose name the Certificate so surrendered is registered, if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment shall pay any transfer or other Taxes required by reason of such Certificate and establish to the satisfaction of Parent that such Tax has been paid or is not applicable. Until surrendered or transferred as contemplated by this Section 2.2, each Certificate or Book-Entry Share (other than Certificates or Book-Entry Shares representing any Dissenting Company Shares or Excluded Company Shares) shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender or transfer the amount of Merger Consideration, without interest, into which the shares of Company Common Stock theretofore represented by such Certificate or Book-Entry Shares shall have been converted pursuant to Section 2.1.

(d) No dividends or other distributions declared or made after the Effective Time with respect to Parent Common Stock, with a record date after the Effective Time, shall be paid to the holder of any unsurrendered Certificate, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 2.2(e), unless and until the holder of such Certificate shall surrender such Certificate in accordance with Section 2.2(c). Subject to the effect of escheat, Tax or other applicable Laws, following surrender of any such Certificate, there shall be paid to the holder of the certificates representing whole shares of Parent Common Stock issued in exchange therefor, without interest, (i) the amount of any cash payable with respect to a fractional share of Parent Common Stock to which such holder is entitled pursuant to Section 2.2(e) and the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Parent Common Stock and (ii) at the appropriate payment date, the amount of dividends or other distributions, with a record date after the Effective Time but prior to surrender and a payment date occurring after surrender, payable with respect to such whole shares of Parent Common Stock.

(e) No certificates or scrip representing fractional shares of Parent Common Stock, or book-entry credit of the same, shall be issued upon the surrender for exchange of Certificates, no dividend or distribution with respect to Parent Common Stock shall be payable on or with respect to any fractional share and such fractional share interests shall not entitle the owner thereof to any rights of a stockholder of Parent. For purposes of this Section 2.2(e), all fractional shares to which a single holder of shares of Company Common Stock would be entitled shall be aggregated and calculations shall be rounded to the fourth decimal point. In lieu of any such fractional share of Parent Common Stock, each holder of Company Common Stock otherwise entitled to a fraction of a share of Parent Common Stock will be entitled to receive from the Paying Agent a cash payment in an amount, rounded up to the nearest cent, equal to the product of (i) such fractional part of a share of Parent Common Stock multiplied by (ii) an amount equal to the average of the closing sale prices for Parent Common Stock on NASDAQ, as reported in The Wall Street Journal, for each of the ten consecutive trading days ending with the seventh complete trading day prior to the Effective Time (the “Parent Share Cash Value”).

Section 2.3 Dissenting Company Shares. Notwithstanding any provision of this Agreement to the contrary, shares of Company Common Stock which are issued and outstanding immediately prior to the Effective Time and which are held by holders who have properly exercised appraisal rights with respect thereto in accordance with Section 262 of the DGCL (the “Dissenting Company Shares”) will not be converted as described in Section 2.1(a)(ii), and holders of such shares will be entitled to receive payment of the value of such shares determined in accordance with the applicable provisions of the DGCL. Notwithstanding the foregoing, if, after the Effective Time, any such holder fails to perfect or effectively withdraws or loses its right to appraisal and payment under the DGCL, the shares of Company Common Stock held by such holder that were Dissenting Company Shares will thereupon be treated as if they had been converted into, at the Effective Time, the right to receive the Merger Consideration, any cash in lieu of fractional shares payable pursuant to Section 2.2(e) and any dividends or other distributions to which such holder is entitled pursuant to Section 2.2(d), without any interest thereon. Upon the Company’s receipt of any notice of intent to demand payment in accordance with the provisions of the DGCL, or any withdrawal of such notice, and any other instruments served pursuant to Section 262 of the DGCL and received by the Company, the Company shall as promptly as reasonably practicable provide Parent with a copy of such notice or instrument. The Company shall give Parent the opportunity to participate in and control all negotiations and proceedings with respect to the exercise of dissenters’ rights under Section 262 of the DGCL. The Company, on the one hand, and Parent, prior to the Closing, on the other hand, shall not, except with the prior written consent of the other party hereto or pursuant to a court order, make any payment with respect to any such election to dissent or offer to settle or settle any such election to dissent.

Section 2.4 No Further Ownership Rights in the Shares. From and after the Effective Time, the holders of shares of Company Common Stock which were outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such shares except as otherwise provided in this Agreement or by applicable Law. All cash paid (including pursuant to Section 2.2(d) or Section 2.2(e)) and all shares of Parent Common Stock and CVR Certificates issued upon the surrender of Certificates and Book-Entry Shares, in each case in accordance with the terms hereof, shall be deemed to have been paid and issued in full satisfaction of all rights pertaining to the shares of Company Common Stock represented by such Certificates and/or such Book-Entry Shares, as applicable.

Section 2.5 Closing of Company Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed and no transfer of shares of Company Common Stock outstanding immediately prior to the Effective Time shall thereafter be made. If, after the Effective Time, Certificates representing shares of Company Common Stock outstanding immediately prior to the Effective Time are presented to the Surviving Corporation or the Paying Agent for any reason, they shall be canceled and exchanged as provided in this ARTICLE II.

Section 2.6 Adjustments. If prior to the Effective Time there is an increase in the number of shares of outstanding Company Common Stock or Company Common Stock subject to outstanding Options or SARs (as each such term is defined in Section 2.7) as a result of a distribution, reclassification, stock split (including a reverse split), stock dividend or distribution, recapitalization, reorganization, merger, subdivision, spin-off, issuer tender or exchange offer, or other similar transaction, the Cash Merger Consideration, the Exchange Ratio, and any other payments to Securityholders based upon the Merger Consideration will be equitably adjusted to eliminate the effects of such event on the Merger Consideration and such other payments.

(a) Since January 1, 2008, Parent has filed with, or furnished to, the SEC all documents required to be filed or furnished by Parent under the Securities Act or the Exchange Act (collectively, the “Parent SEC Documents”). As of their respective dates, Parent SEC Documents complied in all material respects with the requirements of the Securities Act or the Exchange Act, as the case may be, and as of their respective dates and except as amended or supplemented prior to the date hereof (or with respect to Parent SEC Documents filed or furnished after the date hereof, except as amended or supplemented prior to the Closing Date), none of Parent SEC Documents contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, except that no representation is made by Parent with respect to information supplied by the Company or its Subsidiaries in writing for inclusion in the Registration Statement. Each of the consolidated financial statements of Parent (including, in each case, any notes thereto) included in Parent SEC Documents (collectively, the “Parent Financial Statements”) have been prepared in accordance with U.S. GAAP applied on a consistent basis during the periods involved (except as may be indicated therein or in the notes thereto) and fairly present in all material respects the financial position of Parent and its consolidated Subsidiaries as at the dates thereof and the results of their operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal year-end audit adjustments and to any other adjustments set forth therein).

(b) To the Knowledge of Parent, neither Parent nor any of its Subsidiaries has any liability or obligation of any nature (whether accrued, absolute, contingent or otherwise), except for liabilities, obligations or contingencies which (i) are reflected, or for which reserves are established, on the consolidated balance sheet of Parent as of March 31, 2010, (ii) were incurred in the ordinary course of business since March 31, 2010, (iii) would not reasonably be expected to have, individually or in the aggregate, a Parent Material Adverse Effect or (iv) have been incurred in connection with the performance by Parent of its obligations under this Agreement or the transactions contemplated hereby.

(d) To the Knowledge of Parent, since January 1, 2008 and prior to the date of this Agreement, none of Parent, any of its Subsidiaries or any director, officer, auditor, accountant or representative of Parent or any of its Subsidiaries has received any substantive complaint, allegation, assertion or claim, whether written or oral, that Parent or any of its Subsidiaries has engaged in questionable accounting or auditing practices. No current or former attorney representing Parent or any of its Subsidiaries has reported evidence of a material violation of securities Laws, breach of fiduciary duty or similar violation by Parent or any of its Subsidiaries, or any of their respective officers, directors, employees or agents, to Parent’s current board of directors or any committee thereof or to any current director or executive officer of Parent.

(e) Parent and its Subsidiaries have designed and maintain internal controls over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act) to provide reasonable assurances (i) regarding the reliability of Parent’s financial reporting and the preparation of financial statements for external purposes in accordance with U.S. GAAP (ii) that receipts and expenditures of Parent and its Subsidiaries are being made only in accordance with the authorization of management and directors of Parent and such Subsidiaries and (iii) regarding prevention or timely detection of the unauthorized acquisition, use or disposition of Parent’s or its Subsidiaries’ assets that could have a material effect on Parent’s financial statements. Parent has designed and maintains disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Exchange Act) to ensure that material information required to be disclosed by Parent in the reports that Parent files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and is accumulated and communicated to Parent’s management as appropriate to allow timely decisions regarding required disclosure and to make the certifications of the principal executive officer and principal financial officer of Parent required under the Exchange Act with respect to such reports.

(f) Neither Parent nor any of its Subsidiaries is a party to, or has any commitment to become a party to, any joint venture, off balance sheet partnership or any similar Contract binding on Parent or any of its Subsidiaries or any of their properties or assets (including any Contract binding on Parent or any of its Subsidiaries or any of their properties or assets or arrangement relating to any transaction or relationship between or among Parent and any of its Subsidiaries, on the one hand, and any unconsolidated affiliate, including any structured finance, special purpose or limited purpose entity or person, on the other hand, or any “off balance sheet arrangements” (as defined in Item 303(a) of Regulation S-K under the Exchange Act)), where the result, purpose or intended effect of such Contract is to avoid disclosure of any material transaction involving, or material liabilities of, Parent or any of its Subsidiaries in Parent’s or such Subsidiary’s published financial statements or other documents required to be filed or furnished by Parent under the Securities Act or the Exchange Act.

(g) Since January 1, 2009, Parent has not received any oral or written notification of any “material weakness” in Parent’s internal control over financial reporting. There is no outstanding “significant deficiency” or “material weakness” that Parent’s independent accountants certify has not been appropriately and adequately remedied by Parent. For purposes of this Agreement, the terms “significant deficiency” and “material weakness” shall have the meanings assigned to them in Release No. 2007-005 of the Public Company Accounting Oversight Board, as in effect on the date hereof.

For purposes of this Agreement, “Parent Material Adverse Effect” means any Effects, that, in the aggregate with all other Effects, is, or would reasonably be expected to be, (1) materially adverse to the business, assets, financial condition or results of operations of Parent and its Subsidiaries taken as a whole, or (2) prevent the consummation of the Merger; provided that in no event shall any of the following, alone or in combination, be deemed to constitute, nor shall any of the following be taken into account in determining whether there has been, or there would reasonably be expected to be, a Parent Material Adverse Effect: (a) any Effect relating to, or resulting from, any change or developments in or to local, regional, national or foreign political, economic or financial conditions or in or to local, regional, national or foreign credit, financial, banking or securities markets (including any disruption thereof), including any Effect caused by acts of terrorism or war or armed hostilities (whether or not declared), (b) any Effect affecting generally any of the industries, geographic areas or business segments in which Parent or any of its Subsidiaries operates, (c) any Effect relating to, or resulting from, any hurricane, earthquake or other natural disasters, (d) any change in the share price or trading volume (as opposed to the facts underlying such change) of Parent Common Stock on NASDAQ (provided, however, that the facts and circumstances giving rise to such Effect that are not otherwise excluded from the definition of Parent Material Adverse Effect may be considered for purposes of determining whether there has been, or would reasonably be expected to be, a Parent Material Adverse Effect), (e) any Effect relating to, or resulting from, the adoption, implementation, promulgation, repeal, modification or proposal of any Law or U.S. GAAP, after the date of this Agreement, (f) any failure, in and of itself (as opposed to the facts underlying such failure), to meet any budgets, plans, projections or forecasts of Parent’s or its Subsidiaries’ revenue, earnings or other financial performance or results of operations, or any published financial forecasts or analyst estimates with respect to the revenue, earnings or other financial performance or results of operations of Parent or its Subsidiaries or any change in analyst recommendations, for any period (provided, however, that the facts and circumstances giving rise to such failures that are not otherwise excluded from the definition of Parent Material Adverse Effect may be considered for purposes of determining whether there has been, or there

would reasonably be expected to be, a Parent Material Adverse Effect may be considered for purposes of determining whether there has been, or would reasonably be expected to be, a Parent Material Adverse Effect), or (g) any Effect directly relating to, or resulting from, the execution, performance or announcement of this Agreement or the Related Agreements (including the impact thereof on relationships, contractual or otherwise, with customers, suppliers, licensors, licensees, distributors, partners or employees, the loss or departure of officers or other employees of Parent or its Subsidiaries and any pending or threatened Proceeding challenging this Agreement, any of the Related Agreements or the transactions contemplated hereby or thereby, or otherwise resulting from the pursuit of the consummation of the transactions contemplated hereby or thereby; except that clauses (a), (b), (c) and (e), shall not be applicable with respect to Effects to the extent, but only to the extent, that any such Effects have had, or would reasonably be expected to have, a disproportionate impact on Parent and its Subsidiaries, taken as a whole, relative to other participants in the industry in which Parent and its Subsidiaries operate.

Section 4.7 Proxy Statement/Prospectus and Registration Statement. None of the information supplied or to be supplied by Parent or any of its Subsidiaries for inclusion or incorporation by reference in the Registration Statement or the Proxy Statement/Prospectus at the time the Registration Statement becomes effective under the Securities Act or at the time the Proxy Statement/Prospectus is mailed to stockholders of the Company and at the time of the Company Stockholders Meeting will contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading, except that no representation is made by Parent or Sub with respect to information supplied by the Company for inclusion or incorporation by reference in any of such documents.

For the purposes of this Agreement, the term “Solvent” when used with respect to any Person, means that, as of any date of determination (a) the amount of the “fair saleable value” of the assets of such Person will, as of such date, exceed (i) the value of all “liabilities of such Person, including contingent and other liabilities,” as of such date, as such quoted terms are generally determined in accordance with applicable Laws governing determinations of the insolvency of debtors, and (ii) the amount that will be required to pay the probable liabilities of such Person on its existing debts (including contingent and other liabilities) as such debts become absolute and mature, and (b) such Person will be able to pay its liabilities, including contingent and other liabilities, as they mature. For purposes of this definition, “able to pay its liabilities, including contingent and other liabilities, as they mature” means that such Person will be able to generate enough cash from operations, asset dispositions or refinancing, or a combination thereof, to meet its obligations as they become due.

Section 4.14 No Other Representations or Warranties. Except for the representations and warranties expressly contained in this Agreement, the Company acknowledges that neither Parent, Sub or any other Person on behalf of Parent or Sub makes any other express or implied representation or warranty with respect to Parent, any of its Subsidiaries or their respective businesses or any other matter or with respect to any other information provided or made available to the Company, and that all such representations and warranties, other than the representations and warranties of Parent and Sub expressly contained in this Agreement, are expressly disclaimed.

(a) Subject to the provisions of this Section 6.3, after the date hereof and prior to the Effective Time, the Company agrees that the Company and its Subsidiaries shall not, and that it shall use its reasonably best efforts to cause the officers, directors, employees, investment bankers, attorneys and other advisors or representatives (collectively, “Representatives”) of the Company or its Subsidiaries to not, (i) solicit, initiate, or knowingly encourage the making, submission or announcement of any inquiry regarding, or any proposal or offer which would reasonably be expected to lead to, a merger, acquisition, consolidation, tender offer, exchange offer or other transaction involving, or any proposal or offer to purchase or acquire in any manner, directly or indirectly, (A) assets (including equity interests of a Company Subsidiary) representing 15% or more of the assets or revenues of the Company and its Subsidiaries taken as a whole, or (B) 15% or more of the voting securities of the Company, other than, in each case, transactions with Parent (any such proposal or offer being hereinafter referred to as an “Acquisition Proposal”), (ii) enter into, participate, continue or otherwise engage in discussions or negotiations with, or provide any non-public information to any Person (other than Parent, Sub and their Representatives) with respect to any inquiries regarding, or the making, submission or announcement of, an Acquisition Proposal, (iii) enter into or approve any letter of intent, agreement in principle, option agreement, share purchase agreement, acquisition agreement or similar agreement for an Acquisition Proposal, or (iv) terminate, waive, amend or modify any provision of, or grant permission under, any standstill, confidentiality agreement or similar contract to which the Company or any Company Subsidiary is a party; provided, that the foregoing shall not prohibit the Board of Directors from terminating, waiving, amending or modifying any provision of, or granting permission under, any standstill, confidentiality agreement or similar contract if the Board of Directors determines in good faith that the failure to take such action, would be reasonably likely to constitute a breach of the Board of Directors’ fiduciary duties to the Company’s stockholders under applicable Law. The Company shall (i) immediately cease and cause to be terminated any existing solicitation, discussion or negotiation with any Person (other than Parent, Sub or their Representatives) conducted prior to the date of this Agreement by the Company, its Subsidiaries or any of their respective Representatives with respect to any actual or potential Acquisition Proposal and (ii) as promptly as reasonably practicable request that all confidential information provided by or on behalf of the Company or any of its Subsidiaries to such third party be returned or destroyed.

(b) Subject to the provisions of this Section 6.3, the Company may, and may authorize any of its Representatives to, prior to the date on which the Stockholder Approval is obtained, (A) in response to a request by a Person who has made a bona fide written Acquisition Proposal that was not initiated or solicited in violation of Section 6.3(a), provide information to such Person (including to potential financing sources of such Person), if the Company receives from such Person so requesting the information an executed confidentiality agreement no more favorable in any material respect to such Person than the Confidentiality Agreement (as defined in Section 6.4) is to Parent (it being agreed that the Company shall promptly provide to Parent, in accordance with the terms of the Confidentiality Agreement, any information concerning the Company or its Subsidiaries provided to such other Person which was not previously provided to Parent); and/or (B) engage in discussions or negotiations with any Person (and such Person’s potential financing sources) who has made a bona fide written Acquisition Proposal that was not initiated or solicited in violation of Section 6.3(a), if, in each case, the Board of Directors determines in good faith after consultation with the Company’s financial advisor and outside legal counsel that (1) failure to take this action would be reasonably likely to constitute a breach of its fiduciary duties to the Company’s stockholders under applicable Law and (2) the Acquisition Proposal either constitutes a Superior Proposal or is reasonably likely to lead to a Superior Proposal. As used in this Agreement, “Superior Proposal” means an unsolicited, bona fide written Acquisition Proposal made after the date hereof (for this purpose substituting “60%” for each reference to 15% in the definition of “Acquisition Proposal”) and that the Board of Directors determines in good faith (after consultation with the Company’s financial advisor and outside legal counsel) is reasonably expected to be consummated on the terms proposed, taking into account all legal, financial and regulatory aspects of the proposal, including the financing terms thereof and the Person making such proposal, and if consummated would result in a transaction that is more favorable to the stockholders of the Company from a financial point of view than the transactions contemplated by this Agreement (after taking into account any revisions to the terms of the transactions contemplated by this Agreement agreed to by Parent pursuant to Section 6.3(c)).

(c) The Company shall notify Parent orally and in writing promptly (and in any event within 24 hours) after receipt of any Acquisition Proposal or any request for information or inquiry which could reasonably be expected to lead to an Acquisition Proposal. The written notice shall include the identity of the Person making such Acquisition Proposal, request or inquiry, the material terms of the Acquisition Proposal, request or inquiry (including any material written amendments or modifications, or any proposed material written amendments or modifications, thereto), and the Company shall keep Parent reasonably informed on a current basis of any material changes with respect to such Acquisition Proposal, request or inquiry. The Company shall provide Parent with at least 36 hours prior notice (or such shorter notice as may be provided to the Board of Directors) of any meeting of the Board of Directors at which the Board of Directors is reasonably expected to determine that an Acquisition Proposal is a Superior Proposal. The Company shall not exercise its right to terminate this Agreement pursuant to Section 8.1(e) hereof, and any purported termination pursuant thereto shall be void of no force or effect, until after the fifth Business Day following Parent’s receipt from the Company of written notice (i) advising Parent that the Board of Directors has received a Superior Proposal, specifying the material terms and conditions of the Superior Proposal (and attaching a copy of the definitive agreement related thereto, if available) and stating that the Board of Directors intends to exercise its right to terminate this Agreement pursuant to Section 8.1(e). The Company agrees that after notifying Parent that an Acquisition Proposal is a Superior Proposal, including during the five-Business Day period specified in the preceding sentence (such period, the “Parent Review Period”), Parent will be permitted to propose to the Company revisions to the terms of the transactions contemplated by this Agreement, and the Company and its Representatives will, if requested by Parent, consider in good faith any revisions to the terms of the transactions contemplated by this Agreement proposed by Parent. The Company shall not be entitled to terminate this Agreement pursuant to Section 8.1(e) if Parent has, during the Parent Review Period, made a binding offer that, after consideration of such offer by the Board of Directors in good faith and after consultation with the Company’s financial advisor and outside legal counsel, results in the Board of Directors concluding that such Superior Proposal no longer constitutes a Superior Proposal. In the event of any amendment to the consideration or any other material revisions to the Superior Proposal, the Company shall be required to deliver a new written notice to Parent and to comply with the requirements of this Section 6.3(c) with respect to such new written notice (including a new Parent Review Period except that the new Parent Review Period shall be three Business Days).

(d) The Company agrees that any action taken by any of its Subsidiaries or a Representative of the Company or any of its Subsidiaries that, if taken by the Company, would constitute a breach of the restrictions set forth in this Section 6.3, shall be deemed to be a breach of this Agreement (including this Section 6.3) by the Company.

(e) Nothing contained in this Section 6.3 shall prohibit the Company or its Board of Directors from taking and disclosing to the Company’s stockholders a position with respect to a tender offer by a third party pursuant to Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act or from making such disclosure to the Company’s stockholders which, in the judgment of the Board of Directors after receiving advice of outside legal counsel, is reasonably likely to be required under applicable Law.

Section 6.4 Access to Information; Confidentiality. The Company shall, and shall cause each of its Subsidiaries to, (i) afford to Parent and its Representatives, upon reasonable notice, reasonable access during normal business hours during the period prior to the Effective Time to all their respective employees, agents, properties, books, Contracts, commitments and records; provided, however, that such access shall not unreasonably disrupt the Company’s operations, and (ii) furnish promptly such information concerning the business, properties, Contracts, assets, liabilities, personnel and other aspects of the Company and its Subsidiaries as Parent or its Representatives may reasonably request. Notwithstanding anything to the contrary in this Section 6.4, (x) the Company shall not be required to provide any information which it reasonably believes it may not provide Parent or Sub by reason of applicable Law (including antitrust Laws), which constitutes information protected by attorney/client privilege, or which the Company or any Subsidiary is required to keep confidential by reason of Contracts with third parties and (y) with respect to the Trade Secrets included in the Company Intellectual Property, prior to the Effective Time the Company will provide during normal business hours, to not more than three Representatives of Parent selected by Parent, reasonable access to documentation related to Trade Secrets, provided that such individuals execute a separate confidentiality agreement with the Company covering chemistry, manufacturing and controls and related matters in a form substantially identical to the form previously executed by Parent’s employees. The parties will use reasonable best efforts to make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply. All information exchanged pursuant to this Section 6.4 shall be subject to the confidentiality agreement, dated October 16, 2009 (the “Confidentiality Agreement”), between the Company and Parent.

Section 6.5 Reasonable Best Efforts; Notification.

(a) Upon the terms and subject to the conditions set forth in this Agreement, each of the parties shall use its reasonable best efforts to take, or cause to be taken, all reasonable actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things reasonably necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Merger, including (i) the obtaining of all Consents and the making of all Registrations specified in Section 3.3(c) and Section 4.4 and the taking of all reasonable steps as may be necessary to obtain such Consents and to make such Registrations, (ii) the obtaining of all necessary consents, approvals or waivers from third parties, (iii) the defending of any lawsuits or other Proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the Merger, including, seeking to have any stay or temporary restraining order entered by any court or other Governmental Entity vacated or reversed, 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; provided, however, that the obligations set forth in this sentence shall not be deemed to have been breached as a result of actions taken by the Company that are permitted under Section 6.3. Notwithstanding the foregoing, neither Parent or Sub, on the one hand, and the Company, on the other hand, shall be obligated to amend or waive the provisions of any Contract, or obligated to pay any consent or similar fees or payments, unless such action is conditioned upon the consummation of the Merger. Without limiting the foregoing, none of the parties shall take or agree to take any action that could reasonably be expected to result in any of the conditions set forth in Article VII not being satisfied or to prevent or materially delay the consummation of the Merger or the transactions contemplated by this Agreement.

(b) Without limiting the foregoing, each of Parent and the Company undertakes and agrees to file as soon as practicable, and in any event prior to 10 Business Days after the date hereof, a Notification and Report Form under the HSR Act with the United States Federal Trade Commission (the “FTC”) and the Antitrust Division of the United States Department of Justice (the “Antitrust Division”). Each of Parent and the Company shall (i) respond as promptly as practicable to any inquiries received from the FTC or the Antitrust Division for additional information or documentation and to all inquiries and requests received from any state attorney general or other Governmental Entity in connection with antitrust matters, and (ii) not extend any waiting period under the HSR Act or enter into any agreement with the FTC or the Antitrust Division not to consummate the transactions contemplated by this Agreement, except with the prior written consent of the other parties hereto (which consent shall not be unreasonably withheld or delayed). Parent shall use its reasonable best efforts to avoid or eliminate impediments under any antitrust, competition, or trade regulation law that may be asserted by the FTC, the Antitrust Division, any state attorney general or any other Governmental Entity with respect to the Merger so as to enable the consummation thereof as promptly as reasonably practicable and shall defend through litigation on the merits any claim asserted in any court by any party, including appeals. Without limiting the foregoing and subject to this Section 6.5(b), Parent shall propose, negotiate, 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, effective as of the Effective Time, the Surviving Corporation, or their respective Subsidiaries or otherwise commit to take any action which it is capable of taking, take or commit to take such action that limits its freedom of action with respect to, or its ability to retain, any of the businesses, services or assets of Parent, the Surviving Corporation or their respective Subsidiaries, in order to avoid the entry of, or to effect the dissolution of, any injunction, temporary restraining order or other order in any suit or Proceeding, or any impediment under any antitrust Law, competition, or trade regulation Law, which would otherwise have the effect of preventing the consummation of the Merger. Notwithstanding any of the foregoing, nor anything else contained in this Agreement, Parent shall not be required to sell, divest or otherwise dispose of, hold separate, enter into any license or similar agreement with respect to, restrict the ownership or operation of, or agree to sell, divest or otherwise dispose of, hold separate, enter into any license or similar agreement with respect to, or restrict the ownership or operation of (i)(A) any assets or businesses of the Company or any of its Subsidiaries or (B) any assets or businesses of Parent or any of its Affiliates or Subsidiaries, in the case of either clause (A) or (B), to the extent that such sale, divestiture, disposition, or agreement would have a material adverse effect on the business, operations, financial condition or results of operations of the combined business of Parent and the Company after giving effect to the consummation of the transactions contemplated by this Agreement, or (ii) the Product to the extent such sale, divestiture, disposition, agreement or restriction would have a material adverse effect on the ability of the Company to exploit the Product in the Applicable Jurisdictions. The Company shall agree if, and solely if, requested by Parent, to divest, hold separate or otherwise take or commit to take any action that limits its freedom of action with respect to, or its ability to retain, any of the businesses, services, or assets of the Company or any of its Subsidiaries, provided

that any such action shall be conditioned upon the consummation of the Merger and the transactions contemplated hereby. Each party shall (i) promptly notify the other party of any material communication to that party from the FTC, the Antitrust Division, any state attorney general or any other Governmental Entity and, subject to applicable Law, permit the other party to review in advance any proposed written communication to any of the foregoing; (ii) to the extent practicable not agree to participate in any substantive meeting or discussion with any Governmental Entity in respect of any filings, investigation or inquiry concerning this Agreement or the Merger unless it consults with the other party in advance and, to the extent permitted by such Governmental Entity, gives the other party the opportunity to attend and participate thereat; and (iii) furnish the other party with copies of all correspondence, filings, and communications (and memoranda setting forth the substance thereof) between them and their Affiliates and their respective Representatives on the one hand, and any Governmental Entity or members of their respective staffs on the other hand, with respect to this Agreement and the Merger. Subject to its obligations in Section 6.5(a), Parent shall have the right to determine and direct the strategy and process by which the parties will seek required approvals under antitrust, competition or trade regulation Laws; provided that Parent will consult with and consider in good faith the views of the Company in connection with proceedings under or relating to any such Laws.

Section 6.6 Benefit Plans.

(a) During the period beginning on the Effective Time and ending no earlier than December 31, 2011 (the “Transition Period”), Parent shall provide, or shall cause the Surviving Corporation to provide, each active employee of the Company or its Subsidiaries as of the Effective Time (each, an “Employee”) with salary, cash bonus opportunities and employee benefits (including equity-based benefits) that are not materially less favorable in the aggregate than (i) the salary, cash bonus opportunities and employee benefits in effect with respect to such Employee on the date of this Agreement or as increased after the date of this Agreement consistent with the provisions of Section 5.1(j); (ii) the salary, cash bonus opportunities and employee benefits generally provided by Parent and its Subsidiaries (other than the Surviving Corporation and its Subsidiaries) from time to time to employees of Parent and its Subsidiaries (other than the Surviving Corporation and its Subsidiaries) in the country that is such Employee’s principal place of employment who are similarly situated to such Employee in title, rank, tenure (counting tenure with the Company and its Subsidiaries prior to the Effective Time to the extent recognized by the Company or its Subsidiaries prior to the Effective Time and reflected on the books and records of the Company) and job duties; or (iii) any combination of the foregoing (e.g., during the Transition Period, Parent may transition an Employee into one or more of its employee benefit programs while maintaining the Employee’s salary and cash bonus opportunities as in effect immediately prior to the Effective Time); provided, that, (x) for purposes of and subject to this Section 6.6(a), Parent shall determine in its sole discretion the combination of compensation and benefits described in clauses (i) through (iii) to be provided to any Employee during the Transition Period and (y) nothing in this Section 6.6(a) shall be deemed to prohibit Parent from changing the title, rank or job duties of any Employee at any time after the Effective Time.

(b) To the extent that Employees become eligible to participate in any “employee benefit plan,” as defined in Section 3(3) of ERISA, maintained by Parent or any of its Subsidiaries (collectively, the “Parent Plans”), then for purposes of determining eligibility to participate and vesting and, with respect to any Parent Plan that provides severance, vacation or paid-time off benefits, for purposes of benefit accrual, service with the Company or any of its Subsidiaries prior to the Effective Time shall be treated as service with Parent or any of its Subsidiaries, in each case except as prohibited by an insurer or service provider under a Parent Plan or by applicable Law; provided, however, that such service shall not be recognized to the extent that such recognition would result in any duplication of benefits. In addition, subject to the terms of the applicable Parent Plan and applicable Law, Parent shall use reasonable best efforts to (i) waive all limitations as to preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to the Employees under any Parent Plan that is a welfare benefit plan in which such Employees may be eligible to participate after the Effective Time and (ii) provide each Employee with credit for any co-payments and deductibles paid prior to the Effective Time in satisfying any applicable deductible or out-of-pocket requirements under any Parent Plans that are welfare plans in which such Employees are eligible to participate after the Effective Time.

(c) Unless Parent directs the Company otherwise in writing no later than five Business Days prior to the Effective Time, the Board of Directors shall adopt resolutions terminating, effective at least one day prior to the Effective Time, the Company’s 401(k) Retirement Plan. Prior to the Effective Time, the Company shall provide Parent with executed resolutions of the Board of Directors authorizing such termination in a form reasonably acceptable to Parent. The Company shall also take such other actions in furtherance of the termination of the Company’s 401(k) Retirement Plan as Parent may reasonably require.

(d) Nothing contained in this Section 6.6 shall (i) be treated as an amendment of any particular Parent Plan, (ii) give any third party any right to enforce or confer upon the applicability of the provisions of this Section 6.6 or (iii) obligate Parent or any of its Subsidiaries to (A) maintain any particular Employee Benefit Plan or Parent Plan or (B) retain the employment of any particular Employee.

(e) Parent shall, or shall cause the Surviving Corporation to, comply with the provisions set forth on Section 6.6(e) of the Disclosure Schedule.

Section 6.7 Fees and Expenses.

(b) Subject to Section 6.7(d), the Company agrees to pay Parent a fee equal to $145,000,000 if:

(i) this Agreement is terminated by (A) the Company pursuant to Section 8.1(e) (in which case, the fee shall be payable at the time of termination) or (B) Parent pursuant to Section 8.1(c)(ii) or Section 8.1(d) (in which case, the fee shall be payable within two Business Days after such termination);

(ii) (x) this Agreement is terminated by Parent pursuant to Section 8.1(c)(i), (y) prior to the date upon which the breach giving rise to Parent’s right to terminate this Agreement pursuant to Section 8.1(c)(i) occurs but after the date hereof, a bona fide Acquisition Proposal (which, for purposes of this Section 6.7(b), shall have the meaning set forth in the definition of Acquisition Proposal contained in Section 6.3(a), except that all references to 15% shall be deemed references to “60%”) for the Company shall have been publicly announced (other than by Parent or its Affiliates) and (z) within 12 months after such termination either the Company shall have entered into a definitive agreement relating to an Acquisition Proposal or a transaction contemplated by an Acquisition Proposal for the Company shall have been consummated (in which case, the fee shall be payable within two Business Days thereafter);

(iii) (x) this Agreement is terminated by Parent or the Company pursuant to Section 8.1(b)(iii), (y) prior to the date of the Company Stockholder Meeting but after the date hereof, a bona fide Acquisition Proposal for the Company shall have been publicly announced (other than by Parent or its Affiliates) and (z) within 12 months after such termination either the Company shall have entered into a definitive agreement relating to an Acquisition Proposal or a transaction contemplated by an Acquisition Proposal for the Company shall have been consummated (in which case, the fee shall be payable within two Business Days thereafter); or

(iv) (w) this Agreement is terminated by Parent or the Company pursuant to Section 8.1(b)(i), (x) prior to such termination, the Antitrust Approval shall have been obtained, (y) prior to such termination but after the date hereof, a bona fide Acquisition Proposal for the Company shall have been publicly announced (other than by Parent or its Affiliates) and (z) within 12 months after such termination either the Company shall have entered into a definitive agreement relating to an Acquisition Proposal or a transaction contemplated by an Acquisition Proposal for the Company shall have been consummated (in which case, the fee shall be payable within two Business Days thereafter).

(c) The fee payable pursuant to Section 6.7(b) shall be made by wire transfer of same day funds to an account designated in writing by Parent. The Company acknowledges that the agreements contained in Section 6.7(b) are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Parent and Sub would not enter into this Agreement; accordingly, if the Company fails to promptly pay the amount due pursuant to Section 6.7(b), and, in order to obtain such payment, Parent or Sub commences a suit which results in a binding nonappealable judgment rendered by a court of competent jurisdiction against the Company for the fee set forth in Section 6.7(b), the Company shall pay to Parent or Sub its reasonable documented costs and expenses (including reasonable attorneys’ fees) in connection with such suit together with interest on the amount due at the prime rate of Bank of America N.A. in effect on the date such payment was required to be made hereunder plus 2% per annum.

(d) Parent agrees that, except in the case of fraud or a willful and material breach hereof (as defined in Section 8.2), the payment provided for in Section 6.7(b) shall be the sole and exclusive remedy of Parent upon termination of this Agreement under circumstances giving rise to an obligation (or potential obligation) of the Company to pay the amounts set forth in Section 6.7(b) and such remedy shall be limited to the aggregate of the sums stipulated in such Section 6.7(b). In no event shall the Company be required to pay to Parent more than one termination fee pursuant to Section 6.7(b).

Section 6.8 Public Announcements.

Thereafter, Parent and Sub, on the one hand, and the Company, on the other hand, shall use reasonable efforts to consult with each other before issuing, and provide each other the opportunity to review and comment upon, any press release or other public statements with respect to the Merger and the other transactions contemplated by this Agreement and, unless it has made reasonable efforts to do the foregoing, shall not issue any such press release or make any such public statement prior to such consultation, except as may be required by applicable Law, court process or by obligations pursuant to any listing agreement with any national securities exchange. Notwithstanding the foregoing provisions of this Section 6.8, Parent and the Company and their respective Representatives may make public releases or announcements concerning the transactions contemplated hereby that are not inconsistent with previous press releases or other public statements made by Parent and/or the Company in compliance with this Section 6.8.

Section 6.9 Sub. Parent will take all action necessary (a) to cause Sub to perform its obligations under this Agreement to consummate the Merger in accordance with the terms and subject to the conditions set forth in this Agreement and (b) to ensure that, prior to the Effective Time, Sub shall not conduct any business or make any investments other than as specifically contemplated by this Agreement.

Section 6.13 Certain Notices. Subject to compliance with all applicable Laws, the Company and Parent, as the case may be, shall confer on a regular basis with each other, report on operational matters and shall promptly advise each other orally and in writing upon becoming aware of any Event having, or which would be reasonably likely to have, individually or in the aggregate, a Company Material Adverse Effect. Parent and the Company shall give prompt notice to the other of any Event of which it obtains Knowledge that would be reasonably expected to materially delay or prevent the consummation of the Merger. Furthermore, the Company shall give prompt notice to Parent, and Parent or Sub shall give prompt notice to the Company, upon, to the Knowledge of the Company or the Knowledge of Parent, as applicable (i) any representation or warranty made by it in this Agreement becoming untrue or inaccurate in any material respect, (ii) the occurrence of any condition, event or circumstance that would be reasonably expected to result in any of the conditions in Section 7.2(a) or Section 7.3(a) not being met, or (iii) the failure by it to comply with or satisfy in any material respect any covenant or agreement to be complied with or satisfied by it under this Agreement; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of, or the conditions to the obligations of, the parties hereto under this Agreement.

Prior to the Effective Time, Parent’s board of directors, or an appropriate committee of non-employee directors thereof, shall adopt a resolution consistent with the interpretive guidance of the SEC so that the acquisition by any officer or director of the Company who is a covered Person of the Company for purposes of Section 16 of Parent Common Stock pursuant to this Agreement and the Merger shall be an exempt transaction for purposes of Section 16.

Section 6.15 State Takeover Laws. If any “fair price,” “moratorium,” “control share acquisition,” “business combination” or other similar anti-takeover statute or regulation enacted under state or federal laws in the United States becomes or is deemed to be applicable to the Company, Parent, Sub, the Merger or the Voting Agreement or any other transaction contemplated by this Agreement, the Board of Directors shall take all action necessary to render such Law inapplicable to the foregoing.

Section 8.1 Termination. This Agreement may be terminated at any time prior to the Effective Time, whether before or after receipt of the Stockholder Approval:

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

(b) by either Parent or the Company:

(i) if the Closing shall not have occurred on or before March 31, 2011 (the “Termination Date”); provided, however, that the right to terminate this Agreement under this Section 8.1(b)(i) shall not be available to any party whose failure to fulfill any obligation under this Agreement has been the cause of, or resulted in, the failure of the Closing to occur on or before the Termination Date; or

(ii) if any Governmental Entity in an Applicable Jurisdiction shall have issued or entered a permanent injunction or other order that is in effect preventing or prohibiting the consummation of the Merger and such injunction or order shall have become final and nonappealable; provided that the right to terminate this Agreement pursuant to this Section 8.1(b)(ii) shall not be available to any party whose failure to fulfill any obligation under this Agreement (including such party’s obligations set forth in Section 6.5) has been the cause of, or resulted in, such action; or

(iii) if, upon a vote at a duly held Company Stockholder Meeting (including any postponement or adjournment thereof) to obtain the Stockholder Approval in accordance with this Agreement, the Stockholder Approval is not obtained;

(c) by Parent, if (i) the Company breaches or fails to perform any of its representations, warranties, covenants or obligations contained in this Agreement, in any case, as a result of which a condition set forth in Section 7.2(a) or Section 7.2(b) will not be able to be satisfied prior to or as of the Termination Date (provided that Parent or Sub is not then in breach of any representation, warranty or covenant contained in this Agreement such that the conditions set forth in Section 7.3(a) or Section 7.3(b) would not then be satisfied), or (ii) the Company breaches or fails to perform in any material respect its obligations under Section 6.3;

(f) by the Company, if Parent or Sub breaches or fails to perform any of its representations, warranties, covenants or obligations contained in this Agreement, in any case, as a result of which a condition set forth in Section 7.3(a) or Section 7.3(b) will not be able to be satisfied prior to or as of the Termination Date (provided that the Company is not then in material breach of any representation, warranty or covenant contained in this Agreement).

Section 8.2 Effect of Termination. In the event of termination of this Agreement by either the Company or Parent as provided in Section 8.1, this Agreement shall forthwith become void and have no effect, without any liability or obligation on the part of Parent, Sub or the Company, other than the last sentence of Section 6.4, Section 6.7, this Section 8.2 and Article IX, which provisions shall survive such termination, and provided that nothing herein shall relieve any party from liability for any fraud or willful and material breach hereof.

Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.

Section 8.5 Procedure for Termination, Amendment, Extension or Waiver. A termination of this Agreement pursuant to Section 8.1, an amendment of this Agreement pursuant to Section 8.3 or an extension or waiver pursuant to Section 8.4 shall, in order to be effective, require in the case of Parent, Sub or the Company, action by its board of directors or the duly authorized designee of its board of directors.

or to such other address as any party may have furnished to the other parties in writing in accordance with this Section 9.2.

Section 9.3 Specific Performance. The parties hereby acknowledge and agree that the failure of any party to perform its agreements and covenants hereunder in accordance with their specific terms, including its failure to take all actions as are necessary on its part to consummate the transactions contemplated hereby, will cause irreparable injury to the other party, for which damages, even if available, will not be an adequate remedy. Accordingly, each party hereby consents to the issuance of temporary, preliminary and permanent injunctive relief in any court of the United States or any state having jurisdiction to compel performance of such party’s obligations, or to prevent breaches or threatened breaches of this Agreement, and to the granting by any such court of the remedy of specific performance of its obligations hereunder, without, in any such case, the requirement to post any bond or other undertaking, in addition to any other rights or remedies available hereunder or at law or in equity. Each of the parties further agrees that it will not oppose, and hereby waives any defense to, the granting of an injunction, specific performance and other equitable relief on the basis that the other parties have an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity. Each of the parties further waives any requirement under any Law to post security as a prerequisite to obtaining equitable relief.

Section 9.4 Assignment; Binding Effect. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto (whether by operation of Law or otherwise) without the prior written consent of the other parties. Subject to the preceding sentence, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns.

Section 9.5 Entire Agreement. This Agreement, the Disclosure Schedule, the Confidentiality Agreement, the Related Agreements constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings among the parties with respect thereto.

(b) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. 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 SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH SUCH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (iv) EACH SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.
