AGREEMENT AND PLAN OF MERGER dated as of July 22, 2009 (this “Agreement”), by and among Xxxxxxx-Xxxxx Squibb Company, a Delaware corporation (“Parent”), Puma Acquisition Corporation, a New Jersey corporation and a wholly-owned subsidiary of Parent (“Sub”), and Medarex, Inc., a New Jersey corporation (the “Company”).

WHEREAS Parent is the beneficial owner of 2,879,223 shares of common stock, par value $.01 per share, of the Company (the “Company Common Stock”), including the associated Company Rights, representing approximately 2.2% of the outstanding shares of Company Common Stock;

WHEREAS Parent desires to acquire the remaining outstanding shares of Company Common Stock, including the associated Company Rights, on the terms and subject to the conditions set forth in this Agreement;

WHEREAS in furtherance of the acquisition of the remaining outstanding shares of Company Common Stock by Parent on the terms and subject to the conditions set forth in this Agreement, Parent proposes to cause Sub to make a tender offer (as it may be amended from time to time as permitted under this Agreement, the “Offer”) to purchase all the remaining outstanding shares of Company Common Stock, including the associated Company Rights, for consideration of a price per share of Company Common Stock (including the associated Company Rights) of $16.00 (such amount, or any other amount per share paid pursuant to the Offer and this Agreement, the “Offer Price”), net to the seller in cash, without interest, on the terms and subject to the conditions set forth in this Agreement;

WHEREAS the Boards of Directors of each of the Company and Sub have approved the merger of Sub with and into the Company (the “Merger”), on the terms and subject to the conditions set forth in this Agreement; and

WHEREAS Parent, Sub and the Company desire to make certain representations, warranties, covenants and agreements in connection with the Offer and the Merger and also to prescribe various conditions to the Offer and the Merger.

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth herein, the parties hereto agree as follows:

ARTICLE I

The Offer

SECTION 1.01. The Offer. (a) Subject to the terms of this Agreement, as promptly as practicable (but in no event later than seven business days) after the date of this Agreement, Sub shall, and Parent shall cause Sub to, commence, within the meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as amended (together with the rules and regulations promulgated thereunder, the “Exchange Act”), the Offer.

The obligations of Sub to, and of Parent to cause Sub to, accept for payment, and pay for, any shares of Company Common Stock tendered pursuant to the Offer are subject to the conditions set forth in Exhibit A (the “Offer Conditions”). The initial expiration date of the Offer shall be midnight, New York City time, on the 20th business day following the commencement of the Offer (determined pursuant to Rule 14d-1(g)(3) under the Exchange Act). Sub expressly reserves the right, in its sole discretion, to waive, in whole or in part, any Offer Condition or modify the terms of the Offer; provided, however, that, without the prior written consent of the Company, Sub shall not (i) reduce the number of shares of Company Common Stock subject to the Offer, (ii) reduce the Offer Price, (iii) change, modify or waive the Minimum Tender Condition, (iv) add to the conditions set forth in Exhibit A or modify or change any Offer Condition in a manner adverse in any material respect to any holders of Company Common Stock, (v) except as otherwise provided in this Section 1.01(a), extend or otherwise change the expiration date of the Offer, (vi) change the form of consideration payable in the Offer or (vii) otherwise amend, modify or supplement any of the terms of the Offer in a manner adverse in any material respect to any holders of Company Common Stock. Notwithstanding anything in this Agreement to the contrary, Sub may, in its sole discretion, without consent of the Company, (A) without limiting Parent’s or Sub’s obligations under the following sentence, extend the Offer on one or more occasions, in consecutive increments of up to five business days (or such longer period as the parties hereto may agree) each, if on any then-scheduled expiration date of the Offer any of the Offer Conditions shall have occurred and be continuing, until such time as such condition or conditions shall no longer exist, (B) extend the Offer for any period required by any rule, regulation, interpretation or position of the Securities and Exchange Commission (the “SEC”) or the staff thereof applicable to the Offer and (C) if Parent determines in good faith that a filing with the German Federal Cartel Office (the “GFCO”) is required in connection with the Offer or the Merger, extend the Offer on one or more occasions, in increments of up to five business days (or such longer period as the parties hereto may agree) each, for an aggregate period of time of not more than 25 business days, until the waiting period required by the GFCO (and any extension thereof) has been terminated or has expired. Parent and Sub agree that, to the extent requested in writing by the Company prior to any then-scheduled expiration date of the Offer, Sub shall (and Parent shall cause Sub to) (A) if any of the Offer Conditions set forth in clause (ii) of Exhibit A or in paragraph (a), (b) or (d)(2) of clause (iii) of Exhibit A shall have occurred and be continuing on such then-scheduled expiration date (and have not been waived by Sub), and provided that it is reasonably expected that such condition or conditions shall cease to exist prior to the Termination Date, extend the Offer on one or more occasions, in consecutive increments of up to five business days each (or such longer period as the parties hereto may agree), until such time as such Offer Conditions no longer exist and (B) if any of the Minimum Tender Condition or the Offer Conditions set forth in paragraph (d) (other than paragraph (d)(2)) or (e) of clause (iii) of Exhibit A shall have occurred and be continuing on such then-scheduled expiration date (and have not been waived by Sub), but all the other Offer Conditions set forth in Exhibit A shall not have occurred and be continuing on such then-scheduled expiration date, extend the Offer on one or more occasions, in consecutive increments of up to five business days (or such longer period as the parties hereto may agree) each, for an aggregate period of time of not more than 20 business days. On the

terms and subject to the conditions of the Offer and this Agreement, Sub shall, and Parent shall cause Sub to, accept and pay for (subject to any withholding of tax pursuant to Section 1.01(d)) all shares of Company Common Stock validly tendered and not validly withdrawn pursuant to the Offer that Sub becomes obligated to purchase pursuant to the Offer as soon as practicable after the expiration date of the Offer (as it may be extended and re-extended in accordance with this Section 1.01(a)). Acceptance for payment of shares of Company Common Stock pursuant to and subject to the conditions of the Offer is referred to in this Agreement as the “Offer Closing”, and the date on which the Offer Closing occurs is referred to in this Agreement as the “Offer Closing Date”. Sub expressly reserves the right, in its sole discretion, to extend the Offer for a “subsequent offering period” in accordance with Rule 14d-11 under the Exchange Act following the Offer Closing, and the Offer Documents may, in Sub’s sole discretion, provide for such a reservation of right. The Offer may not be terminated prior to its expiration date (as such expiration date may be extended and re-extended in accordance with this Section 1.01(a)), unless this Agreement is validly terminated in accordance with Article VIII. If the Offer is terminated or withdrawn by Sub, or this Agreement is terminated in accordance with Section 8.01, prior to the acceptance for payment of Company Common Stock tendered in the Offer, Sub shall promptly return, and shall cause any depository acting on behalf of Sub to return, all tendered Company Common Stock to the registered holders thereof. Nothing contained in this Section 1.01(a) shall affect any termination rights in Article VIII.

(b) On the date of commencement of the Offer, Parent and Sub shall file with the SEC a Tender Offer Statement on Schedule TO filed under cover of Schedule TO with respect to the Offer, which shall contain an offer to purchase and a related letter of transmittal and summary advertisement (such Schedule TO and the documents included therein pursuant to which the Offer will be made, together with any supplements or amendments thereto, the “Offer Documents”). The Company shall promptly furnish to Parent and Sub all information concerning the Company required by the Exchange Act to be set forth in the Offer Documents. Each of Parent, Sub and the Company shall promptly correct any information supplied by it for inclusion or incorporation by reference in the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect, and each of Parent and Sub shall take all steps necessary to amend or supplement the Offer Documents and to cause the Offer Documents as so amended or supplemented to be filed with the SEC and disseminated to the holders of Company Common Stock, in each case as and to the extent required by applicable Federal securities Laws. Parent and Sub shall promptly notify the Company upon the receipt of any comments from the SEC, or any request from the SEC for amendments or supplements, to the Offer Documents, and shall provide the Company with copies of all correspondence between them and their representatives, on the one hand, and the SEC, on the other hand. Prior to the filing of the Offer Documents (including any amendment or supplement thereto) with the SEC or dissemination thereof to the shareholders of the Company, or responding to any comments of the SEC with respect to the Offer Documents, Parent and Sub shall provide the Company a reasonable opportunity to review and comment on such Offer Documents or response (including the proposed final version thereof), and Parent and Sub shall give reasonable consideration to any such comments.

(c) Parent shall provide or cause to be provided to Sub on a timely basis the funds necessary to pay for any shares of Company Common Stock that Sub becomes obligated to accept for payment, and pay for, pursuant to the Offer.

(d) Sub shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to the Offer to any holder of shares of Company Common Stock such amounts as Sub is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), or any other Law. To the extent that amounts are so withheld and paid over by Sub to the appropriate Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock in respect of which such deduction and withholding was made by Sub.

SECTION 1.02. Company Actions. (a) The Company hereby approves of and consents to the Offer, the Merger and the other transactions contemplated by this Agreement.

(b) On or as promptly as practicable after the date the Offer Documents are filed with the SEC, the Company shall file with the SEC a Solicitation/ Recommendation Statement on Schedule 14D-9 with respect to the Offer (such Schedule 14D-9, together with any supplements or amendments thereto, the “Schedule 14D-9”) containing the recommendation described in Section 4.01(d)(i) and shall mail the Schedule 14D-9 to the shareholders of the Company. Parent and Sub shall promptly furnish to the Company all information concerning Parent and Sub required by the Exchange Act to be set forth in the Schedule 14D-9. Each of the Company, Parent and Sub shall promptly correct any information supplied by it for inclusion or incorporation by reference in the Schedule 14D-9 if and to the extent that such information shall have become false or misleading in any material respect, and the Company shall take all steps necessary to amend or supplement the Schedule 14D-9 and to cause the Schedule 14D-9 as so amended or supplemented to be filed with the SEC and disseminated to the shareholders of the Company, in each case as and to the extent required by applicable Federal securities Laws. The Company shall promptly notify Parent upon the receipt of any comments from the SEC, or any request from the SEC for amendments or supplements, to the Schedule 14D-9, and shall provide Parent with copies of all correspondence between the Company and its representatives, on the one hand, and the SEC, on the other hand. Prior to the filing of the Schedule 14D-9 (including any amendment or supplement thereto) with the SEC or mailing thereof to the shareholders of the Company, or responding to any comments of the SEC with respect to the Schedule 14D-9, the Company shall provide Parent a reasonable opportunity to review and comment on such Schedule 14D-9 or response (including the proposed final version thereof), and the Company shall give reasonable consideration to any such comments. The Company hereby consents to the inclusion in the Offer Documents of the recommendation of the Board of Directors of the Company contained in the Schedule 14D-9.

(c) In connection with the Offer and the Merger, the Company shall cause its transfer agent to furnish Parent and Sub promptly with mailing labels containing the

names and addresses of the record holders of Company Common Stock as of a recent date and of those persons becoming record holders subsequent to such date, together with copies of all lists of shareholders, security position listings and computer files and all other information in the Company’s possession or control regarding the beneficial owners of Company Common Stock, and shall furnish to Sub such information and assistance (including updated lists of shareholders, security position listings and computer files) as Parent may reasonably request in communicating the Offer to holders of Company Common Stock. Subject to the requirements of applicable Law, and except for such steps as are necessary to disseminate the Offer Documents and any other documents necessary to consummate the transactions contemplated by this Agreement, Parent and Sub shall hold in confidence the information contained in any such labels, listings and files in accordance with the requirements of the Confidentiality Agreement dated June 2, 2009 between Parent and the Company (as it may be amended from time to time, the “Confidentiality Agreement”), shall use such information only in connection with the Offer and the Merger and, if this Agreement shall be terminated, shall, upon request, destroy all copies of such information then in their possession or control.

SECTION 1.03. Top-Up Option. (a) The Company hereby grants to Sub an irrevocable option (the “Top-Up Option”), exercisable only on the terms and conditions set forth in this Section 1.03, to purchase at a price per share equal to the Offer Price paid in the Offer up to that number of newly issued shares of Company Common Stock (the “Top-Up Shares”) equal to the lowest number of shares of Company Common Stock that, when added to the number of shares of Company Common Stock owned by Parent and its Subsidiaries at the time of exercise of the Top-Up Option, shall constitute one share more than 90% of the shares of Company Common Stock outstanding immediately after the issuance of the Top-Up Shares on a “fully diluted basis” (which assumes conversion or exercise of all derivative securities regardless of the conversion or exercise price, the vesting schedule or other terms and conditions thereof); provided, however, that (i) the Top-Up Option shall not be exercisable for a number of shares of Company Common Stock in excess of the shares of Company Common Stock authorized and unissued or held in the treasury of the Company at the time of exercise of the Top-Up Option (giving effect to the shares of Company Common Stock issuable pursuant to all then-outstanding stock options, restricted stock units and any other rights to acquire Company Common Stock as if such shares were outstanding), (ii) the issuance of the Top-Up Shares shall not require approval of the Company’s shareholders under applicable Law (including the rules of The NASDAQ Stock Market LLC (“NASDAQ”)) and (iii) the exercise of the Top-Up Option and the issuance and delivery of the Top-Up Shares shall not be prohibited by any Law or Judgment. The Top-Up Option shall be exercisable at any one time following the Offer Closing and prior to the earlier to occur of (a) the Effective Time and (b) the termination of this Agreement in accordance with its terms. The obligation of the Company to issue and deliver the Top-Up Shares upon the exercise of the Top-Up Option is subject only to the condition that no Legal Restraint that has the effect of preventing the exercise of the Top-Up Option or the issuance and delivery of the Top-Up Shares in respect of such exercise shall be in effect.

(b) The parties shall cooperate to ensure that the issuance and delivery of the Top-Up Shares comply with all applicable Laws, including compliance with an

applicable exemption from registration of the Top-Up Shares under the Securities Act. In the event Sub wishes to exercise the Top-Up Option, Sub shall give the Company at least three business days prior written notice, specifying (i) the number of shares of the Company Common Stock owned by Parent and its Subsidiaries at the time of such notice and (ii) a place and a time for the closing of such purchase. The Company shall, as soon as practicable following receipt of such notice, deliver written notice to Sub specifying, based on the information provided by Sub in its notice, the number of Top-Up Shares. At the closing of the purchase of Top-Up Shares, the purchase price owed by Sub to the Company therefor shall be paid to the Company (i) in cash, by wire transfer or cashier’s check or (ii) by issuance by Sub to the Company of a promissory note on terms reasonably satisfactory to the Company.

(c) Parent and Sub acknowledge that the Top-Up Shares that Sub may acquire upon exercise of the Top-Up Option will not be registered under the Securities Act and will be issued in reliance upon an applicable exemption from registration under the Securities Act. Each of Parent and Sub hereby represents and warrants to the Company that Sub is, and will be, upon the purchase of the Top-Up Shares, an “accredited investor,” as defined in Rule 501 of Regulation D under the Securities Act. Sub agrees that the Top-Up Option and the Top-Up Shares to be acquired upon exercise of the Top-Up Option are being and will be acquired by Sub for the purpose of investment and not with a view to, or for resale in connection with, any distribution thereof (within the meaning of the Securities Act of 1933, as amended (including the rules and regulations promulgated thereunder, the “Securities Act”)).

ARTICLE II

The date on which the Closing occurs is referred to in this Agreement as the “Closing Date”.

SECTION 2.03. Effective Time of the Merger. Upon the terms and subject to the conditions set forth in this Agreement, as soon as practicable on or after the

Closing Date, a certificate of merger (the “Certificate of Merger”) shall be duly prepared, executed and acknowledged by the Parent and, to the extent applicable, the Company, in accordance with the relevant provisions of the NJBCA and shall be filed by Parent with the Department of Treasury of the State of New Jersey (the “Department of Treasury”). The Merger shall become effective on such date and at such time as the Certificate of Merger is duly filed with the Department of Treasury or at such subsequent date and time, not to exceed 90 days after the date of filing the Certificate of Merger, as Parent and the Company shall agree and specify in the Certificate of Merger. The date and time at which the Merger becomes effective is referred to in this Agreement as the “Effective Time”.

ARTICLE III

Effect of the Merger on the Capital Stock of the Constituent Corporations; Exchange
of Certificates

SECTION 3.01. Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of Company Common Stock, or the holder of any shares of capital stock of Parent or Sub:

(a) Capital Stock of Sub. Each share of common stock of Sub, par value $0.01 per share, issued and outstanding immediately prior to the Effective Time shall be converted into and become one validly issued, fully paid and

nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation.

(b) Cancellation of Treasury Stock and Parent-Owned Stock. All shares of Company Common Stock that are owned as treasury stock by the Company or owned by Parent or Sub immediately prior to the Effective Time shall automatically be canceled and shall cease to exist, and no consideration shall be delivered or deliverable in exchange therefor.

(c) Conversion of Company Common Stock. Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than shares to be canceled in accordance with Section 3.01(b)) shall be converted into the right to receive from the Surviving Corporation, in cash and without interest, an amount equal to the Offer Price paid in the Offer (the “Merger Consideration”). At the Effective Time such shares shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of a certificate, or evidence of shares held in book-entry form, that immediately prior to the Effective Time represented any such shares (a “Certificate”) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration in accordance with the terms of this Agreement.

(d) Adjustment Events. If, between the date of this Agreement and the Effective Time, the outstanding shares of Company Common Stock are changed into, or exchanged for, a different number or class of shares by reason of any stock dividend, split, combination, subdivision or reclassification of shares, reorganization, recapitalization or other similar transaction, then the Offer Price and the Merger Consideration (as applicable) payable per share of Company Common Stock shall be adjusted to the extent appropriate to fairly reflect the effects of such transaction.

SECTION 3.02. Exchange of Certificates. (a) Paying Agent. Prior to the Effective Time, Parent shall enter into an agreement with such bank or trust company as may be designated by Parent and reasonably acceptable to the Company to act as agent for the payment of the Merger Consideration upon surrender of Certificates (the “Paying Agent”). At the Effective Time, Parent shall, or shall cause the Surviving Corporation to, deposit with the Paying Agent funds in amounts and at the times necessary for the payment of the Merger Consideration pursuant to Section 3.01(c) upon surrender of Certificates, it being understood that any and all interest or other amounts earned with respect to such funds shall be for the account of and turned over to Parent in accordance with Section 3.02(g).

(b) Exchange Procedure. As soon as reasonably practicable after the Effective Time, Parent shall cause the Paying Agent to mail to each holder of record of a Certificate (i) a form of letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates held by such person shall pass, only upon proper delivery of the Certificates to the Paying Agent and shall be in a form and

have such other provisions as Parent may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. Upon surrender of a Certificate for cancellation to the Paying Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly completed and validly executed, and such other documents as may reasonably be required by the Paying Agent, the holder of such Certificate shall be entitled to receive in exchange therefor the amount of Merger Consideration that such holder has the right to receive pursuant to Section 3.01(c), and the Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of Company Common Stock that is not registered in the stock transfer books of the Company, payment of the Merger Consideration in exchange therefor may be made to a person other than the person in whose name the Certificate so surrendered is registered if, upon presentation to the Paying Agent, 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 the payment to a person other than the registered holder of such Certificate or establish to the satisfaction of the Surviving Corporation that such taxes have been paid or are not applicable. No interest shall be paid or shall accrue on the cash payable upon surrender of any Certificate.

(c) No Further Ownership Rights in Company Common Stock. All cash paid upon the surrender of a Certificate in accordance with the terms of this Article III shall be deemed to have been paid in full satisfaction of all rights pertaining to the shares of Company Common Stock formerly represented by such Certificate. At the close of business on the day on which the Effective Time occurs, the stock transfer books of the Company shall be closed, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares that were outstanding immediately prior to the Effective Time. If, after the close of business on the day on which the Effective Time occurs, Certificates are presented to the Surviving Corporation or the Paying Agent for transfer or any other reason, they shall be canceled and exchanged as provided in this Article III.

(d) No Liability. None of Parent, Sub, the Company, the Surviving Corporation or the Paying Agent shall be liable to any person in respect of any cash that would otherwise have been payable in respect of any Certificate that is delivered to a public official in accordance with any applicable abandoned property, escheat or similar Law. If any Certificates shall not have been surrendered prior to the date which is one year after the Effective Time (or immediately prior to such earlier date on which any Merger Consideration would otherwise escheat to or become the property of any Governmental Entity), any such Merger Consideration in respect thereof shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation, free and clear of all claims or interest of any person previously entitled thereto.

(e) Lost Certificates. If any Certificate shall have been lost, stolen, defaced or destroyed, upon the making of an affidavit of that fact in form and substance reasonably satisfactory to Parent by the person claiming such Certificate to be lost, stolen, defaced or destroyed and, if required by the Surviving Corporation, the posting by such person of a bond in such amount as the Surviving Corporation may direct as

indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent shall pay the Merger Consideration in respect of such lost, stolen, defaced or destroyed Certificate.

(f) Withholding Rights. Parent, the Surviving Corporation or the Paying Agent, as applicable, shall be entitled to deduct and withhold from the Merger Consideration otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock such amounts as Parent, the Surviving Corporation or the Paying Agent is required to deduct and withhold with respect to the making of such payment under the Code or any other Law. To the extent that amounts are so withheld and paid over to the appropriate Governmental Entity by Parent, the Surviving Corporation or the Paying Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock in respect of which such deduction and withholding was made by Parent, the Surviving Corporation or the Paying Agent.

(g) Termination of Fund. At any time following the date which is six months after the Effective Time, Parent or the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any funds (including any interest or other amounts earned with respect thereto) that had been made available to the Paying Agent and which have not been disbursed to holders of Certificates, and thereafter, subject to the time limitations in Section 3.02(d), such holders shall be entitled to look only to the Surviving Corporation (subject to abandoned property, escheat or similar Laws) as general creditors thereof with respect to the payment of any Merger Consideration that may be payable upon surrender of any Certificates held by such holders, as determined pursuant to this Agreement, without any interest thereon.

(a) Organization, Standing and Corporate Power. The Company is a corporation duly organized and validly existing and in good standing under the laws of the State of New Jersey, each of its Subsidiaries is a corporation duly organized, validly existing and in good standing (in the jurisdictions that recognize the concept of good standing) under the laws of the jurisdiction of its incorporation or formation, as the case may be, and each of the Company and its

Subsidiaries has all requisite power and authority and possesses all governmental licenses, franchises, permits, authorizations and approvals necessary to enable it to use its corporate or other name and to own, lease or otherwise hold and operate its properties and other assets and to carry on its business as presently conducted and as currently proposed by its management to be conducted, except where the failure to be in good standing (except with respect to the Company), have such power or authority or possess such governmental licenses, permits, authorizations or approvals, individually or in the aggregate, has not had and would not reasonably be expected to have a Material Adverse Effect. Each of the Company and its Subsidiaries is duly qualified or licensed to do business and is in good standing (in jurisdictions that recognize the concept of good standing) in each jurisdiction in which the nature of its business or the ownership, leasing or operation of its properties makes such qualification or licensing necessary, other than in such jurisdictions where the failure to be so qualified or licensed or to be in good standing, individually or in the aggregate, has not had and would not reasonably be expected to have a Material Adverse Effect. The Company has made available to Parent, prior to the execution of this Agreement, complete and accurate copies of the Company Certificate and its By-laws (the “Company By-laws”), and the comparable organizational documents of each of its Subsidiaries, in each case as amended to the date hereof. The Company has made available to Parent complete and accurate copies of the minutes (or, in the case of minutes that have not yet been finalized, drafts thereof) of, and resolutions approved and adopted at, all meetings of the shareholders of the Company and each of its Subsidiaries, the Boards of Directors of the Company and each of its Subsidiaries and the committees of each of such Boards of Directors, in each case held since January 1, 2007 and prior to the date hereof, except for that portion of any minutes that discuss the Merger or the other transactions contemplated by this Agreement or any current or prior alternatives thereto considered by the Board of Directors of the Company or any such committee thereof.

(b) Subsidiaries. Section 4.01(b) of the Company Disclosure Schedule lists each Subsidiary of the Company and, for each such Subsidiary, the jurisdiction of incorporation or formation and each jurisdiction in which such Subsidiary is qualified or licensed to do business. All issued and outstanding shares of capital stock of, or other equity interests in, each such Subsidiary have been validly issued and are fully paid and nonassessable and are owned directly or indirectly by the Company free and clear of all pledges, liens, charges, encumbrances or security interests of any kind or nature whatsoever (other than liens, charges and encumbrances for current taxes not yet due and payable) (collectively, “Liens”), and free of any restriction on the right to vote, sell or otherwise dispose of such capital stock or other equity interests. Except for the capital stock of, or voting securities or equity interests in, its Subsidiaries, the Company does not own, directly or indirectly, any capital stock of, or other voting securities or equity interests in, any corporation, limited liability company, partnership, joint venture, association or other entity.

(iii) Since the close of business on July 21, 2009 until the date of this Agreement, (A) there have been no issuances by the Company of shares of capital stock or other voting securities or equity interests of the Company, other than issuances of shares of Company Common Stock (including the associated Company Rights) pursuant to the conversion of the Convertible Notes, the exercise of Company Stock Options and purchase rights under the Purchase Plan and the settlement of Company RSUs, in each case outstanding as of the close of business on July 21, 2009, and only in accordance with their terms as in effect on such date, and (B) there have been no issuances by the Company of securities convertible into, or exchangeable or exercisable for, or options, warrants or other rights to acquire, or shares of deferred stock, restricted stock units, stock-based performance units, stock appreciation rights or “phantom” stock awards with respect to, any such stock, interests or securities, or

derivative securities or other rights that are linked to the value of Company Common Stock or the value of the Company or any part thereof, other than purchase rights under the Purchase Plan and Company Rights.

(iv) There are no outstanding shares of Company Common Stock or Company Preferred Stock subject to vesting or restrictions on transfer imposed by the Company, and all outstanding Company Stock Options and Company RSUs have been granted under the Company Stock Plans. All grants under the Company Stock Plans of Company Stock Options and Company RSUs were accounted for in accordance with GAAP in the financial statements (including the related notes) of the Company and disclosed in the Company SEC Documents in accordance with the Exchange Act and all other applicable Laws. Each grant of a Company Stock Option was duly authorized no later than the date on which the grant of such Company Stock Option was by its terms to be effective (the “Grant Date”) by all necessary corporate action, including, as applicable, approval by the Board of Directors of the Company (or a duly constituted and authorized committee thereof) and any required shareholder approval by the necessary number of votes or written consents, each such grant was made in accordance with the terms of the applicable compensation plan or arrangement of the Company, the Exchange Act and all other applicable Laws and regulatory rules or requirements, including the rules of the NASDAQ, and the per share exercise price of each Company Stock Option was equal to the fair market value (within the meaning of Section 422 of the Code, in the case of each Company Stock Option intended to qualify as an “incentive stock option”, and within the meaning of Section 409A of the Code, in the case of each other Company Stock Option) of a share of Company Common Stock on the applicable Grant Date. The Company has not knowingly granted, and there is no and has been no Company policy or practice to knowingly grant, Company Options prior to, or otherwise knowingly coordinate the grant of Company Options with, the release or other public announcement of material information regarding the Company or any of its Subsidiaries or their financial results or prospects.

Other than the Company Stock Plans, there is no plan, contract, agreement or arrangement providing for the grant of options to acquire shares of Company Common Stock by the Company or any of its Subsidiaries. All Company Stock Options and Company RSUs that are outstanding as of the date hereof are evidenced by stock option agreements, restricted stock unit agreements or other award agreements, in each case substantially in the forms made available to Parent prior to the date hereof, except that the forms of such agreements differ with respect to the number of Company Stock Options, Company RSUs or shares covered thereby, the exercise price (if applicable), vesting schedule and expiration date applicable thereto and other similar terms; provided that no stock option agreement, restricted stock unit agreement or other award agreement contains terms that are inconsistent in any material respect with, or material terms in addition to, such forms.

(v) As of the close of business on July 21, 2009, there were outstanding Company Stock Options to purchase 18,571,605 shares of Company Common Stock with exercise prices on a per share basis lower than the Merger Consideration, and the weighted average exercise price of such Company Stock Options was equal to $8.07 per share. As of the close of business on July 21, 2009, approximately 9,151 shares of Company Common Stock were subject to outstanding purchase rights under the Purchase Plan based on payroll information for the period ended July 10, 2009 (assuming the fair market value per share of Company Common Stock determined in accordance with the terms of the Purchase Plan on the last day of the offering period in effect under the Purchase Plan on the date hereof will be equal to the Merger Consideration and that payroll deductions continue at the current rate). Each Company Stock Option and each Company RSU may, by its terms, be treated at the Effective Time as set forth in Section 6.04(a)(i) or 6.04(a)(ii), as applicable, and all rights to purchase shares of Company Common Stock under the Purchase Plan may, by their terms, be treated in accordance with Section 6.04(a)(iii). No holder of a Company Stock Option or Company RSU or right to purchase shares of Company Common Stock under the Purchase Plan that is outstanding at the Effective Time is entitled, at the Effective Time, to any treatment of such Company Stock Option or Company RSU or right to purchase shares of Company Common Stock under the Purchase Plan other than as provided in Section 6.04(a), and after the Effective Time no holder of a Company Stock Option or Company RSU or right to purchase shares of Company Common Stock under the Purchase Plan (or former such holder) shall have the right to acquire any capital stock of the Company or any other equity interest therein.

(vi) All outstanding shares of capital stock of the Company are, and all shares which may be issued pursuant to the Convertible Notes, the Company Stock Options, the Company RSUs or purchase rights under the Purchase Plan will be, when issued in accordance with the terms thereof, duly authorized, validly issued, fully paid and nonassessable and not subject to preemptive rights. Except for the Convertible Notes, there are no bonds, debentures, notes or other indebtedness of the Company having the right to vote (or convertible into, or exchangeable for, securities having the right to vote) on any matters on which shareholders of the Company are entitled to vote. Except as set forth above in Section 4.01(b) or this Section 4.01(c), as of the date hereof, (A) there are not issued, reserved for issuance or outstanding (1) any shares of capital stock or other voting securities or equity interests of the Company or any of its Subsidiaries, (2) any securities of the Company or any of its Subsidiaries convertible into or exchangeable or exercisable for shares of capital stock or other voting securities or equity interests of the Company or any of its Subsidiaries, (3) any warrants, calls, options or other rights to acquire from the Company or any of its Subsidiaries, and no obligation of the Company or any of its Subsidiaries to issue, any capital stock, voting securities, equity interests or securities convertible into or exchangeable or exercisable for capital stock or voting securities of the Company or any of its Subsidiaries or (4) any shares of deferred stock, restricted stock units, stock-based performance units, stock

appreciation rights or “phantom” stock awards with respect to any capital stock of the Company or any of its Subsidiaries, or derivative securities or other rights that are linked to the value of the Company Common Stock or the value of the Company, any of its Subsidiaries or any part thereof and (B) there are not any outstanding obligations of the Company or any of its Subsidiaries to repurchase, redeem or otherwise acquire any such securities or to issue, deliver or sell, or cause to be issued, delivered or sold, any such securities (except pursuant to the forfeiture of Company Stock Options and Company RSUs or the acquisition by the Company of shares of Company Common Stock in settlement of the exercise price of a Company Stock Option or the tax withholding obligations of holders of Company Stock Options and Company RSUs, in each case in accordance with their terms as in effect on the date of this Agreement). Neither the Company nor any of its Subsidiaries is a party to any voting or other agreement with respect to the voting of any such securities and, to the knowledge of the Company, as of the date hereof, there are no irrevocable proxies and no voting agreements with respect to any such securities.

(e) Company SEC Documents. (i) The Company has filed or furnished, as applicable, all reports, schedules, forms, statements and other documents (including exhibits and other information incorporated therein) with the SEC required to be filed or furnished, as applicable, by the Company since and including January 1, 2007, under the Securities Act, the Exchange Act and the Xxxxxxxx-Xxxxx Act of 2002 (including the rules and regulations promulgated thereunder, “SOX”) (such documents, together with any documents and

The Company has made available to Parent copies of all comment letters received by the Company from the SEC since January 1, 2006 (excluding all letters received from the SEC indicating that the SEC would not be reviewing any registration statement filed with the SEC by the Company) and relating to the Company SEC Documents, together with all written responses of the Company thereto. As of the date of this Agreement, the Company has not received any written notification of, and to the knowledge of the Company there are no, outstanding or unresolved comments in such comment letters received by the Company from the SEC.

Subsidiaries has any liabilities or obligations of any nature (whether accrued, absolute, contingent or otherwise) that, individually or in the aggregate, would reasonably be expected to have a Material Adverse Effect. None of the Subsidiaries of the Company is, or has at any time been, subject to the reporting requirements of Sections 13(a) and 15(d) of the Exchange Act. Except as disclosed in the most recent audited financial statements (including the notes thereto) included in the Filed Company SEC Documents, neither the Company nor any of its Subsidiaries has any (A) indebtedness for borrowed money, (B) indebtedness evidenced by any bond, debenture, note, mortgage, indenture or other debt instrument or debt security, (C) accounts payable to trade creditors and accrued expenses not arising in the ordinary course of business, (D) amounts owing as deferred purchase price for the purchase of any property or (E) guarantees with respect to any indebtedness or obligation of a type described in clauses (A) through (D) above of any other person (collectively, “indebtedness”), and no indebtedness is subject to, or secured by, any Liens.

(ii) Each of the principal executive officer of the Company and principal financial officer of the Company (or each former such officer) has made all certifications required by Rule 13a-14 or 15d-14 under the Exchange Act and Sections 302 and 906 of SOX with respect to the Company SEC Documents, and the statements contained in such certifications were true and accurate as of the date such certifications were made. The Company maintains a system of “internal control over financial reporting” (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) as required under Rules 13a-15(a) and 15d-15(a) under the Exchange Act and such system is designed to provide reasonable assurance (A) regarding the reliability of the Company’s financial reporting and the preparation of financial statements for external purposes in accordance with GAAP and (B) that transactions of the Company are being made only in accordance with the authorization of management and directors of the Company. The “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) of the Company comply with Rules 13a-15(a) and 15d-15(a) under the Exchange Act and are designed to ensure that all material information relating to the Company and its Subsidiaries is communicated to the Company’s management, including the chief executive officer and chief financial officer of the Company.

(iii) Since January 1, 2007, the Company has not received any oral or written notification of any “material weakness” in the Company’s internal control over financial reporting. There is no outstanding “significant deficiency” or “material weakness” which the Company’s independent accountants certify has not been appropriately and adequately remedied by the Company, other than, in the case of any “significant deficiencies”, any such deficiency which, individually or in the aggregate, has not had or would not reasonably be expected to have a Material Adverse Effect. 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.

result in such person (or in the case of a direct merger between such person and the Company, the shareholders of such person) acquiring, directly or indirectly, more than 50% of the outstanding shares of Company Common Stock or of the voting power of the Company’s capital stock or all or substantially all the assets of the Company and its Subsidiaries, taken as a whole, and which offer the Board of Directors of the Company determines in good faith (after consultation with its outside legal counsel and a financial advisor of nationally recognized reputation) (i) provides a higher value to the shareholders of the Company than the consideration payable in the Offer and the Merger (taking into account all of the terms and conditions of such proposal and this Agreement (including any changes to the terms of the Offer or this Agreement proposed by Parent in response to such Superior Proposal or otherwise)) and (ii) is reasonably capable of being completed in a timely fashion, taking into account all financial, legal, regulatory and other aspects of such proposal.

(b) Neither the Board of Directors of the Company nor any committee thereof shall (i) withdraw or modify in a manner adverse to Parent or Sub, or propose publicly to withdraw or modify in a manner adverse to Parent or Sub, the approval or recommendation by such Board of Directors or any such committee of this Agreement, regarding the Offer or the Merger, or approve or recommend, or propose publicly to approve or recommend any Takeover Proposal, or resolve or agree to take any such action (any such action, resolution or agreement to take such action being referred to herein as an “Adverse Recommendation Change”), or (ii) approve or recommend, or propose publicly to approve, recommend or permit the Company or any of its affiliates to enter into, any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, option agreement, joint venture agreement, partnership agreement or other agreement (each, an “Acquisition Agreement”) constituting or related to, or which is intended to or would reasonably be expected to lead to, any Takeover Proposal (other than a confidentiality agreement referred to in Section 5.02(a)). Notwithstanding anything in this Agreement to the contrary, at any time prior to the Offer Closing, the Board of Directors of the Company may (x) effect an Adverse Recommendation Change, provided that the Board of Directors of the Company determines in good faith (after consultation with its outside legal counsel and a financial advisor of nationally recognized reputation) that the failure to do so would be inconsistent with its fiduciary duties to the shareholders of the Company under applicable Law and (y) in response to a Superior Proposal, cause the Company to terminate this Agreement, provided, concurrently with such termination, the Company pays the fee required by Section 6.06(b)(ii)(B); provided, however, that (1) the Board of Directors of the Company may not effect such an Adverse Recommendation Change and (2) no termination of this Agreement pursuant to this Section 5.02(b) may be made, in each case unless the Company has complied with all its obligations pursuant to this Section 5.02 (other than, in the case of an Adverse Recommendation Change, Section 5.02(a) if, since the date hereof, no Takeover Proposal has been made or otherwise become publicly known and no person has publicly announced an intention to make a Takeover Proposal (in each case, whether or not conditional and whether or not withdrawn)). No Adverse Recommendation Change or termination of this Agreement pursuant to this Section 5.02(b) may be made unless (A) the Board of Directors shall have first provided prior written notice to Parent that it is prepared to (I) effect an Adverse Recommendation

Change (an “Adverse Recommendation Change Notice”) or (II) terminate this Agreement pursuant to this Section 5.02(b) in response to a Superior Proposal (a “Superior Proposal Notice”), which notice shall, if the basis for the proposed action by the Board of Directors of the Company is not related to a Superior Proposal, contain a description of the events, facts and circumstances giving rise to such proposed action or, if the basis for the proposed action by the Board of Directors of the Company is a Superior Proposal, contain a description of the material terms and conditions of such Superior Proposal, and (B) Parent does not make, within three business days after the receipt of such notice, a proposal that would, in the reasonable good faith judgment of the Board of Directors of the Company (after consultation with its outside legal counsel and a financial advisor of nationally recognized reputation), cause such events, facts and circumstances to no longer form the basis for the Board of Directors of the Company to effect an Adverse Recommendation Change or cause the offer previously constituting a Superior Proposal to no longer constitute a Superior Proposal, as the case may be. If Parent has in good faith proposed to the Company revisions to the terms of the transactions contemplated by this Agreement during the three business day period prior to the Company effecting an Adverse Recommendation Change or terminating this Agreement pursuant to this Section 5.02(b), the Company agrees that the Company and its Representatives shall negotiate in good faith with Parent and its Representatives (so long as Parent and its Representatives are negotiating in good faith) regarding any such revisions to the terms of the transactions contemplated by this Agreement proposed by Parent. Any material changes with respect to such events, facts or circumstances mentioned above, or material changes to the financial terms or any material change to other material terms of such Superior Proposal, as the case may be, occurring prior to the Company’s effecting an Adverse Recommendation Change or terminating this Agreement pursuant to this Section 5.02(b) shall require the Company to provide to Parent a new Adverse Recommendation Change Notice or Superior Proposal Notice and a new three business day period and, in determining whether to effect an Adverse Recommendation Change or whether to terminate this Agreement pursuant to this Section 5.02(b), the Board of Directors of the Company shall take into account any such changes.

(c) In addition to the other obligations of the Company set forth in this Section 5.02, the Company shall, as promptly as possible and in any event within 24 hours after the receipt thereof, advise Parent orally and in writing of (i) any Takeover Proposal or any request for information or inquiry that expressly contemplates or could reasonably be expected to lead to a Takeover Proposal and (ii) the material terms and conditions of such Takeover Proposal, request or inquiry (including any change to the financial terms, conditions or other material terms thereof) and the identity of the person making any such Takeover Proposal, request or inquiry. The Company shall (i) make reasonable best efforts to confer with Parent at least once each calendar day and keep Parent reasonably informed of the status (including any change to the financial terms, conditions, or other material terms) of any such Takeover Proposal, request or inquiry and (ii) provide to Parent, as soon as practicable and in any event within 24 hours after receipt or delivery thereof, copies of all draft agreements (and any other written material to the extent such material contains any financial terms, conditions or other material terms relating to any Takeover Proposal) sent by or provided to the Company (or its Representatives) in connection with any such Takeover Proposal.

(d) Nothing contained in this Section 5.02 or elsewhere in this Agreement shall prohibit the Company from (i) taking and disclosing to its shareholders a position contemplated by Rule 14d-9 and Rule 14e-2(a) promulgated under the Exchange Act or complying with Item 1012(a) of Regulation M-A under the Exchange Act or (ii) making any disclosure to its shareholders if, in the good faith judgment of the Board of Directors of the Company (after consultation with outside legal counsel), failure so to disclose is reasonably likely to result in a breach of applicable Law; provided, however, that the taking of any such position or making of any such disclosure contemplated by clauses (i) or (ii) above shall be subject to and only taken in compliance with Section 5.02(b).

Additional Agreements

SECTION 6.01. Preparation of the Proxy Statement; Shareholders Meeting. (a) If the approval of this Agreement by the Company’s shareholders is required by applicable Law, the Company shall, as promptly as practicable following the Offer Closing, prepare and file with the SEC the preliminary Proxy Statement. The Company shall use its reasonable best efforts to cause the definitive Proxy Statement to be mailed to the Company’s shareholders as promptly as practicable after such filing. Each of the Company and Parent shall furnish all information concerning such person to the other as may be reasonably requested in connection with the preparation, filing and distribution of the Proxy Statement. The Company shall promptly notify Parent upon the receipt of any comments from the SEC or any request from the SEC for amendments or supplements to the Proxy Statement and shall provide Parent with copies of all correspondence between it and its Representatives, on the one hand, and the SEC, on the other hand, with respect to the Proxy Statement. Each of the Company and Parent shall use reasonable best efforts to respond as promptly as practicable to any comments of the SEC with respect to the Proxy Statement. Notwithstanding the foregoing, prior to filing or mailing the Proxy Statement (or any amendment or supplement thereto) or responding to any comments of the SEC with respect thereto, the Company (i) shall provide Parent an opportunity to review and comment on such document or response (including the proposed final version of such document or response) and (ii) shall include in such document or response all comments reasonably proposed by Parent. If, at any time prior to the Shareholders Meeting, any information relating to the Company, Parent or any of their respective affiliates, officers or directors should be discovered by the Company or Parent which should be set forth in an amendment or supplement to the Proxy Statement, so that the Proxy Statement does not 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, the party that discovers such information shall promptly notify the other parties hereto, and an appropriate amendment or supplement describing such information shall be filed with the SEC and, to the extent required by applicable Law, disseminated to the shareholders of the Company.

(b) If the approval of this Agreement by the Company’s shareholders is required by applicable Law, the Company shall, as promptly as reasonably practicable

following the Offer Closing (or, with respect to calling, giving notice of, convening and holding a meeting of its shareholders, as soon as reasonably practicable following the expiration of the time period contemplated by Rule 14a-6(a) under the Exchange Act or the resolution of any comments from the SEC), establish a record date (which will be as promptly as reasonably practicable following the Offer Closing) for, duly call, give notice of, convene and hold a meeting of its shareholders (the “Shareholders Meeting”), for the purpose of obtaining the Shareholder Approval. The notice of such Shareholders Meeting shall state that a resolution to approve this Agreement will be considered at the Shareholders Meeting. The Board of Directors of the Company shall recommend to shareholders of the Company that they approve this Agreement, and shall include such recommendation in the Proxy Statement. Notwithstanding the foregoing, if, following the Offer and any subsequent offering period and the exercise, if any, of the Top-Up Option, Parent and its Subsidiaries shall own at least 90% of the outstanding shares of the Company Common Stock, the parties hereto shall take all necessary and appropriate action, including with respect to the transfer to Sub of any shares of Company Common Stock held by Parent or any Subsidiary of Parent, to cause the Merger to become effective as soon as practicable after the Offer Closing without the Shareholders Meeting in accordance with Section 14A:10-5.1 of the NJBCA.

(c) At the Shareholders Meeting, if any, Parent agrees to cause all shares of Company Common Stock acquired pursuant to the Offer and all other shares of Company Common Stock owned by Parent or any Subsidiary of Parent to be voted in favor of the Shareholder Approval.

SECTION 6.02. Access to Information; Confidentiality. The Company shall, and shall cause each of its Subsidiaries to, afford to Parent and to Parent’s Representatives access upon reasonable advance notice and during normal business hours during the period prior to the Effective Time or the termination of this Agreement to all their respective properties, assets, books, records, Contracts, Permits, documents, information, directors, officers and employees, but only to the extent that such access does not unreasonably interfere with the business or operations of the Company and its Subsidiaries (and, to the extent required by applicable Law, access to personnel records will be provided only if authorized by the specific employees), and during such period the Company shall, and shall cause each of its Subsidiaries to, furnish to Parent any information concerning its business as Parent may reasonably request; provided, however, that the Company shall not be required to (or to cause any of its Subsidiaries to) afford such access or furnish such information to the extent that doing so is restricted under applicable Law or otherwise would result in the loss of attorney-client privilege (provided that the Company shall use its reasonable efforts to allow for such access or disclosure in a manner that does not result in a loss of attorney-client privilege). Following the date of this Agreement and prior to the Effective Time, Parent may (but shall not be required to), following reasonable notice to the Company, contact and interview any Company Personnel and review the personnel records and such other information concerning the Company Personnel as Parent may reasonably request, provided such review is permitted by applicable Law. No investigation by Parent or any of its Representatives and no other receipt of information by Parent or any of its Representatives shall operate as a waiver or otherwise affect any representation or

warranty of the Company or any covenant or other provision in this Agreement. Except as required by any applicable Law or Judgment, Parent will hold, and will direct its Representatives to hold, any and all information received from the Company confidential in accordance with the Confidentiality Agreement.

SECTION 6.03. Reasonable Best Efforts; Consultation and Notice. (a) Upon the terms and subject to the conditions set forth in this Agreement, each of the parties hereto agrees to use its reasonable best efforts to take, or cause to be taken, all actions that are necessary, proper or advisable to consummate and make effective the Offer, the Merger and the other transactions contemplated by this Agreement, including using its reasonable best efforts to accomplish the following: (i) the satisfaction of the conditions precedent set forth in Exhibit A and Article VII, (ii) the obtaining of all necessary actions or nonactions, waivers, consents, approvals, orders and authorizations from, and the giving of any necessary notices to, Governmental Entities and other persons and the making of all necessary registrations, declarations and filings (including (A) the filing of a premerger notification and report form by the Company, Parent and Sub under the HSR Act not later than seven business days, or such longer period as to which the parties may mutually agree in writing, after the date of this Agreement and (B) the filing of other registrations, declarations and filings with, or provision of notices to, Governmental Entities, if any), (iii) the taking of all reasonable steps to provide any supplemental information requested by a Governmental Entity, including participating in meetings with officials of such entity in the course of its review of this Agreement, the Offer, the Merger or the other transactions contemplated by this Agreement, (iv) the taking of all reasonable steps as may be necessary to avoid any suit, claim, action, investigation or proceeding by any Governmental Entity or other person and (v) the execution and delivery of any additional instruments necessary to consummate and make effective the Offer, the Merger and the other transactions contemplated by this Agreement. In connection with and without limiting the generality of the foregoing, (A) each of the Company and its Board of Directors shall, if any state takeover statute or similar statute or regulation is or becomes applicable to this Agreement or any of the Offer, the Merger and the other transactions contemplated by this Agreement, use its reasonable best efforts to ensure that the Offer, the Merger and the other transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and otherwise to minimize the effect of such statute or regulation on this Agreement, the Offer, the Merger and the other transactions contemplated by this Agreement and (B) Parent shall be required to, subject to the next sentence, sell, hold separate or otherwise dispose of or conduct its business in a specified manner, agree to sell, hold separate or otherwise dispose of or conduct its business in a specified manner, or permit the conduct of its business in a specified manner or the sale, holding separate or other disposition of, any assets of Parent or its Subsidiaries or, after the Closing, the Company or its Subsidiaries, in each case as may be required to avoid the occurrence of any Offer Condition set forth in clauses (ii) or (iii)(a) or (b) of Exhibit A or to cause any such Offer Condition then existing to cease to exist. Notwithstanding the foregoing or any other provision of this Agreement to the contrary, (I) neither the Company nor any of its Subsidiaries shall be required pursuant to this Section 6.03(a) to complete any disposition of the assets of the Company or any of its Subsidiaries prior to the Closing or enter into any agreement or other arrangement requiring the disposition of

any assets of the Company or any Subsidiary that does not expressly provide that the Company’s obligation to complete such disposition is subject to the prior or simultaneous occurrence of the Closing, (II) under no circumstances will Parent, the Company or any of their respective Subsidiaries be required under this Section 6.03(a) to, and Company and its Subsidiaries shall not without Parent’s written consent, sell, hold separate or otherwise dispose of, agree to sell, hold separate or otherwise dispose of, or permit the sale, holding separate or other disposition of, (x) any Covered Product or Covered Platform, (y) any other product of the Company or any of its Subsidiaries that has been commercialized or is in Phase II or Phase III clinical development (or the foreign equivalent thereof) in the United States or any foreign jurisdiction with respect to any clinical indication of such product or (y) any product of Parent or any of its Subsidiaries that has been commercialized or is in Phase II or Phase III clinical development (or the foreign equivalent thereof) in the United States or any foreign jurisdiction with respect to any clinical indication of such product (the products and platforms in clauses (x), (y) and (z), collectively, the “Specified Assets”), (III) under no circumstances will Parent, the Company or any of their respective Subsidiaries be required under this Section 6.03(a) to, and Company and its Subsidiaries shall not without Parent’s written consent, conduct its business, agree to conduct its business or permit the conduct of its business in any manner that impairs its freedom of action with respect to any Specified Asset and (IV) in no event shall Parent or Sub be obligated to, and the Company and its Subsidiaries shall not, without the prior written consent of Parent, agree to or proffer (x) any limitation on the ability of Parent or any of its Subsidiaries effectively to acquire, hold or exercise full rights of ownership of the shares of Company Common Stock, including the right to vote any shares of Company Common Stock acquired or owned by Parent or any of its Subsidiaries on all matters properly presented to the shareholders of the Company or (y) any divestiture by Parent or any of its Subsidiaries of any shares of Company Common Stock. Notwithstanding the foregoing or any other provision of this Agreement to the contrary, in no event shall Parent or any of its Subsidiaries be obligated to litigate or participate in the litigation of any suit, claim, action, investigation or proceeding, whether judicial or administrative, brought by any Governmental Entity challenging or seeking to restrain, prohibit or place conditions on the consummation of the Offer, the Merger or any of the other transactions contemplated by this Agreement or the ownership or operation by Parent, the Company or any of their respective affiliates of all or any portion of their respective businesses as presently conducted and as currently proposed to be conducted. The Company and Parent shall provide to each other such assistance, information and cooperation as is reasonably required to obtain any such actions, nonactions, waivers, consents, approvals, orders and authorizations and, in connection therewith, shall afford the other person a reasonable opportunity to review and comment on any filings or submissions to any Governmental Entity and shall notify the other person promptly following the receipt of any comments from any Governmental Entity and of any request by any Governmental Entity for amendments, supplements or additional information in respect of any registration, declaration or filing with, or notice to, such Governmental Entity and shall supply the other person with copies of all correspondence between such person or any of its representatives, on the one hand, and any Governmental Entity, on the other hand.

(b) (i) In connection with the continuing operation of the business of the Company and its Subsidiaries between the date of this Agreement and the Effective Time, subject to applicable Law, the Company shall consult in good faith on a reasonably regular basis with Parent to report material, individually or in the aggregate, operational, research and clinical-trial developments, the general status of relationships with its material licensors, licensees and other business partners, the general status of ongoing operations and other matters reasonably requested by Parent pursuant to procedures reasonably requested by Parent; provided, however, that no such consultation shall affect the representations, warranties, covenants, agreements or obligations of the parties (or remedies with respect thereto) or the conditions to the obligations of the parties under this Agreement.

(ii) Except as prohibited by applicable Law, the Company shall promptly notify Parent in writing of:

(A) any written notice or other written communication from any person (other than a Governmental Entity) alleging that the consent of such person is required in connection with the Offer, the Merger or any of the other transactions contemplated by this Agreement;

(B) any written notice or other written communication from any licensor, licensee or other business partner to the effect that such licensor, licensee or other business partner is terminating or otherwise materially adversely modifying its relationship with Company or any of its Subsidiaries as a result of the Offer, the Merger or any of the other transactions contemplated by this Agreement;

(C) its discovery of any fact or circumstance that, or the occurrence or non occurrence of any event the occurrence or non occurrence of which, cause any of the conditions to the Offer set forth in Exhibit A hereto to be in effect at the scheduled Expiration Date;

(D) any notice or other communication from any Governmental Entity received by the Company in connection with the Offer, the Merger or any of the other transactions contemplated by this Agreement, and a copy of any such notice or communication shall be furnished to Parent together with the Company’s written notice;

(E) any filing made by the Company with any Governmental Entity in connection with the Offer, the Merger or any of the other transactions contemplated by this Agreement, and a copy of any such filing shall be furnished to Parent together with the Company’s written notice; and

(F) any suits, actions or proceedings commenced or threatened that relate to the consummation of this Agreement, the Offer, the Merger or any of the other transactions contemplated by this Agreement of which the Company has knowledge;

(iii) Parent shall give prompt notice to the Company of (A) any representation or warranty made by Parent or Sub contained in this Agreement becoming untrue or (B) the failure of Parent or Sub to perform any obligation, covenant or agreement to be performed by such party under this Agreement, in each case in any way that would reasonably be expected to prevent, materially impede or materially delay the consummation by Parent of the Offer, the Merger or the other transactions contemplated by this Agreement; provided, however, that no such notification shall affect the representations, warranties, obligations, covenants or agreements of the parties (or remedies with respect thereto) or the conditions to the obligations of the parties under this Agreement.

SECTION 6.04. Equity Awards. (a) As soon as practicable following the date of this Agreement, the Company agrees that the Board of Directors of the Company (or, if appropriate, any committee administering the Company Stock Plans and the Purchase Plan) shall adopt such resolutions or take such other actions (including obtaining any required consents) as may be required to effect the following:

(i) adjust the terms of all outstanding Company Stock Options such that, at the Effective Time, each unexercised Company Stock Option, whether vested or unvested, that is outstanding immediately prior to the Effective Time, shall be canceled, with the holder of such Company Stock Option becoming entitled to receive, in full satisfaction of the rights of such holder with respect thereto, an amount in cash equal to (A) the excess, if any, of (1) the Merger Consideration over (2) the exercise price per share of Company Common Stock subject to such Company Stock Option, multiplied by (B) the number of shares of Company Common Stock subject to such Company Stock Option immediately prior to the Effective Time (whether vested or unvested), which amount shall be payable to such holder at or as soon as practicable following the Effective Time;

(ii) at the Effective Time, each Company RSU that is outstanding immediately prior to the Effective Time shall be canceled, with the holder of such Company RSU becoming entitled to receive, in full satisfaction of the rights of such holder with respect thereto, an amount in cash equal to the Merger Consideration multiplied by the maximum number of shares of

Company Common Stock subject to such Company RSU immediately prior to the Effective Time, which amount shall be payable to such holder at or as soon as practicable following the Effective Time;

(iii) with respect to the Purchase Plan, (A) participation shall be limited to those employees who are participants on the date of this Agreement; (B) such participants may not increase the rate of their payroll deductions or purchase elections from those in effect on the date of this Agreement; (C) no Purchase Period (as defined in the Purchase Plan) shall be commenced after the date of this Agreement; (D) if, with respect to a Purchase Period in effect on the date of this Agreement, the Effective Time occurs prior to the Purchase Date (as defined in the Purchase Plan) for such Purchase Period, upon the Effective Time, each purchase right under the Purchase Plan outstanding immediately prior to the Effective Time shall be used to purchase from the Company whole shares of Company Common Stock (subject to the provisions of the Purchase Plan regarding the maximum number and value of shares purchasable per participant) at the applicable price determined under the terms of the Purchase Plan for the then outstanding Purchase Period using such date as the final Purchase Date for such Purchase Period, and any remaining accumulated but unused payroll deductions shall be distributed to the relevant participants without interest as promptly as practicable following the Effective Time; and (E) the Purchase Plan shall terminate, effective upon the earlier of the Purchase Date for the Purchase Period in effect on the date of this Agreement and the Effective Time.

Any person making a payment pursuant to this Section 6.04 shall be entitled to deduct and withhold from that payment such amounts as the payor is required to deduct and withhold with respect to the making of such payment under the Code or any other Law. To the extent that amounts are so withheld and paid over by any person pursuant to this Section 6.04 to the appropriate Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the person entitled to payment under this Section 6.04 in respect of which such deduction and withholding was made by a person pursuant to this Section 6.04.

SECTION 6.05. Indemnification, Exculpation and Insurance. (a) Parent and Sub agree that all rights to indemnification, advancement of expenses and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time now existing in favor of the current or former directors or officers of the Company and its Subsidiaries as provided in their respective certificates of incorporation or by-laws (or comparable organizational documents) and any indemnification or other agreements of the Company (as in effect on the date of this Agreement) shall be assumed by the Surviving Corporation in the Merger, without further action, at the Effective Time, and shall survive the Merger and shall continue in full force and effect in accordance with their terms. From and after the Effective Time, Parent and the Surviving Corporation shall be jointly and severally liable to pay and perform in a timely manner such indemnification obligations.

(b) In the event that the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other person and is not the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all its properties and assets to any person, or if Parent dissolves the Surviving Corporation, then, and in each such case, Parent shall cause proper provision to be made so that the successors and assigns of the Surviving Corporation assume the obligations set forth in this Section 6.05.

including coverage and amount, are no less favorable to such directors and officers than the insurance coverage otherwise required under this Section 6.05(c).

(d) The provisions of this Section 6.05 (i) are intended to be for the benefit of, and will be enforceable by, each indemnified party, his or her heirs and his or her representatives and (ii) are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such person may have by Contract or otherwise.

SECTION 6.06. Fees and Expenses. (a) Except as expressly set forth in this Section 6.06, all fees and expenses incurred in connection with this Agreement, the Offer, the Merger and the other transactions contemplated by this Agreement shall be paid by the party incurring such fees or expenses, whether or not the Offer or the Merger is consummated.

(b) In the event that (i) prior to the termination of this Agreement, a Takeover Proposal has been made directly to the shareholders of the Company generally or shall have otherwise become publicly known or any person shall have publicly announced an intention (whether or not conditional and whether or not withdrawn) to make a Takeover Proposal and thereafter (A) this Agreement is terminated by either Parent or the Company pursuant to Section 8.01(b)(i) and (B) within 18 months after such termination, the Company or any of its Subsidiaries enters into any Acquisition Agreement with respect to any Takeover Proposal or any Takeover Proposal is consummated (solely for purposes of this Section 6.06(b)(i)(B), the term “Takeover Proposal” shall have the meaning set forth in the definition of Takeover Proposal contained in Section 5.02(a) except that all references to 15% shall be deemed references to 35%) or (ii) this Agreement is terminated (A) by Parent pursuant to Section 8.01(c) or 8.01(d) or (B) by the Company pursuant to Section 8.01(h), then, in each such case, the Company shall pay Parent a fee equal to $70,800,000 (the “Termination Fee”) by wire transfer of same-day funds to an account designated by Parent (x) in the case of a payment as a result of either event referred to in Section 6.06(b)(i)(B), no later than the first to occur of such events, (y) in the case of a termination by Parent pursuant to Section 8.01(c) or 8.01(d), within three business days after such termination, and (z) in the case of a termination by the Company pursuant to Section 8.01(h), the date of termination of this Agreement.

(c) The Company acknowledges that the agreements contained in Section 6.06(b) are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Parent would not have entered into this Agreement. Accordingly, if the Company fails promptly to pay the amounts due pursuant to Section 6.06(b) and, in order to obtain such payment, Parent commences a suit that results in a judgment against the Company for the amounts set forth in Section 6.06(b), the Company shall pay to Parent its reasonable costs and expenses (including attorneys’ fees and expenses) in connection with such suit and any appeal relating thereto, together with interest on the amounts set forth in Section 6.06(b) at the prime rate of Citibank, N.A. in effect on the date such payment was required to be made.

The parties agree that the initial press release to be issued with respect to the transactions contemplated by this Agreement shall be in the form heretofore agreed to by the parties. Except with respect to any Adverse Recommendation Change made in accordance with the terms of this Agreement, Parent and Sub, on the one hand, and the Company, on the other hand, shall, to the extent at all reasonably practicable, consult with each other before making, and give each other a reasonable opportunity to review and comment upon, any press release or other public statements with respect to this Agreement, the Offer, the Merger and the other transactions contemplated by this Agreement, and shall not issue any such press release or make any such public statement prior to such reasonably practicable consultation, except as may be required by applicable Law, court process or by obligations pursuant to any listing agreement with any national securities exchange or national securities quotation system.

SECTION 6.08. Sub and Surviving Corporation Compliance. Parent shall cause Sub or the Surviving Corporation, as applicable, to perform all of its respective agreements, covenants and obligations under this Agreement and Sub shall not engage in any activities of any nature except as provided in or contemplated by this Agreement.

SECTION 6.09. Directors. (a) Effective upon the Offer Closing, Parent shall be entitled to designate, from time to time, such number of members of the Board of Directors of the Company as will give Parent, subject to compliance with Section 14(f) of the Exchange Act and Rule 14f-1 thereunder, representation equal to at least that number of directors, rounded up to the next whole number, that is the product of (a) the total number of directors (giving effect to the directors elected or appointed pursuant to this sentence) multiplied by (b) the percentage that (i) the number of shares of Company Common Stock owned by Parent and its Subsidiaries (including shares of Company Common Stock accepted for payment pursuant to the Offer) bears to (ii) the number of shares of the Company Common Stock then outstanding; provided, however, that in the event that Parent’s designees are appointed or elected to the Board of Directors of the Company, until the Effective Time the Board of Directors of the Company shall have at least two Independent Directors. The Company shall take all action requested by Parent necessary to effect any such election or appointment, including (A) increasing the size of the Board of Directors of the Company and (B) obtaining the resignation of such number of its current directors as is, in each case, necessary to enable such designees to be so elected or appointed to the Board of Directors of the Company in compliance with applicable Law (including, to the extent applicable prior to the Effective Time, Rule 10A-3 under the Exchange Act and NASDAQ Rules 4350(c) and 4350(d)(2)). The Company shall mail to its shareholders the Information Statement containing the information required by Section 14(f) of the Exchange Act and Rule 14f-1 thereunder, and the Company agrees to make such mailing concurrently with the mailing of the Schedule 14D-9 (provided that Parent and Sub shall have provided to the Company on a timely basis all information required to be included in the Information Statement with respect to such designees and with respect to Parent’s officers, directors and affiliates).

(b) Following the election or appointment of Parent’s designees pursuant to Section 6.09(a) and prior to the Effective Time, the affirmative vote of a majority of the Independent Directors then in office shall be required for the Company to consent (a) to amend or terminate this Agreement, (b) to waive any of the Company’s rights or remedies under this Agreement or (c) to extend the time for the performance of any of the obligations or other acts of Parent or Sub. For purposes of this Agreement, an “Independent Director” shall mean a member of the Company’s Board of Directors who is a member of the Company’s Board of Directors on the date of this Agreement.

SECTION 6.10. Rule 14d-10 Matters. Notwithstanding anything in this Agreement to the contrary, the Company will not, after the date hereof, enter into, establish, amend or modify any plan, program, agreement or arrangement pursuant to which compensation is paid or payable, or pursuant to which benefits are provided, in each case to any Company Personnel unless, prior to such entry into, establishment, amendment or modification, the Compensation and Organization Committee (each member of which the Board of Directors of the Company determined is an “independent director” within the meaning of NASDAQ Rule 4200(a)(15) and shall be an “independent director” in accordance with the requirements of Rule 14d-10(d)(2) under the Exchange Act at the time of any such action) shall have taken all such steps as may be necessary to (i) approve as an Employment Compensation Arrangement each such plan, program, agreement or arrangement and (ii) satisfy the requirements of the non-exclusive safe harbor under Rule 14d-10(d)(2) under the Exchange Act with respect to such plan, program, agreement or arrangement.

SECTION 6.11. Rights Agreement. The Company and its Board of Directors shall take all action requested in writing by Parent in order to render the Company Rights inapplicable to this Agreement, the Offer, the Merger and the other transactions contemplated by this Agreement.

SECTION 6.12. Company Benefit Plan Matters. (a) During the period from the Closing Date until the twelve month anniversary thereof, Parent shall, or shall cause its Subsidiaries to, provide to each person who is employed by the Company or any of its Subsidiaries immediately prior to the Effective Time and who remains in the employment of the Company and its Subsidiaries on or after the Effective Time (the “Continuing Employees”) compensation (including base salary and incentive and bonus opportunities, but excluding equity-based compensation) and benefits (including vacation, paid time off and severance) that are not materially less favorable (taken as a whole) than those provided to the Continuing Employees immediately prior to the Effective Time.

(b) The service of each Continuing Employee with the Company or any of its Subsidiaries (or any predecessor employer) prior to the Effective Time shall be treated as service with Parent and its Subsidiaries for purposes of each (A) “employee pension benefit plan” (as defined in Section 3(2) of ERISA), (B) “employee welfare benefit plan” (as defined in Section 3(1) of ERISA), (C) post-retirement or employment health or medical plan, program, policy or arrangement, (D) bonus, incentive or deferred compensation or equity or equity-based compensation plan, program, policy or

arrangement, (E) severance, change in control, retention or termination plan, program, policy or arrangement or (F) other material compensation or benefit plan, program, policy or arrangement (each, a “Parent Benefit Plan”), in the case of clauses (A) - (F), solely to the extent Parent makes such plan, program, policy or arrangement available to such Continuing Employee after the Effective Time, including for purposes of eligibility, vesting and benefit levels and accruals (other than defined benefit pension plan accruals), but not in any case where credit would result in duplication of benefits.

(c) Following the Effective Time, for purposes of each Parent Benefit Plan in which any Continuing Employee or his or her eligible dependents is eligible to participate after the Effective Time, Parent shall, or shall cause its Subsidiaries to, (i) waive any pre-existing condition, exclusion, actively-at-work requirement or waiting period to the extent such condition, exclusion, requirement or waiting period was satisfied or waived under the comparable Company Benefit Plan or Company Benefit Agreement as of the Effective Time (or, if later, any applicable plan transaction date) and (ii) provide full credit for any co-payments, deductibles or similar payments made or incurred prior to the Effective Time for the plan year in which the Effective Time (or such transition date) occurs.

(d) The parties hereto agree to take the actions set forth on Annex I to this Agreement.

(e) Parent shall, and shall cause its Subsidiaries to, honor, in accordance with its terms, each Company Benefit Plan and Company Benefit Agreement and all obligations thereunder, including any rights or benefits arising as a result of the transactions contemplated by this Agreement (either alone or in combination with any other event), and Parent hereby acknowledges that the consummation of the Offer and the Merger constitutes a change of control or change in control, as the case may be, for all purposes under such Company Benefit Plans and Company Benefit Agreements.

Nothing in this Agreement shall be construed as requiring Parent or any of its Subsidiaries to employ any Continuing Employee for any length of time following the Closing Date. Nothing in this Agreement, express or implied, shall be construed to prevent Parent or any of its Subsidiaries from (i) terminating, or modifying the terms of employment of, any Continuing Employee following the Closing Date or (ii) terminating or modifying to any extent any Company Benefit Plan, Company Benefit Agreement, Parent Benefit Plan or any other employee benefit plan, program, agreement or arrangement that Parent or any of its Subsidiaries may establish or maintain; provided, however, that to the extent that, and for so long as, a Continuing Employee remains employed by Parent or any of its Subsidiaries during the 12 month period following the Closing, the compensation and benefits payable to such employee during such period shall be subject to Section 6.12(a). No covenant or other undertaking in this Agreement shall constitute an amendment to any employee benefit plan, program, policy or arrangement, and any covenant or undertaking that suggests that an employee benefit plan, program, policy or arrangement will be amended shall be effective only upon the adoption of a written amendment in accordance with the amendment procedures of such plan, program, policy or arrangement.

SECTION 6.13. Convertible Notes. (a) The Company shall cause to be filed with the Trustee and to be mailed to each holder of Convertible Notes (each, a “Holder”), in accordance with the terms of the Indenture dated as of May 3, 2004, as amended pursuant to the First Supplemental Indenture dated as of October 4, 2006 (the “Indenture”), between the Company and Wilmington Trust Company, a Delaware banking company, as trustee (the “Trustee”), relating to the Convertible Notes, as promptly as possible after the date hereof but in no event less than 30 days immediately prior to the expected Effective Time, the notice required by Section 12.6 of the Indenture.

(b) The Company shall, on the Closing Date, execute a supplemental indenture to the Indenture that shall give effect to the provisions of Section 12.11 of the Indenture. The Surviving Corporation shall cause notice of the execution of such supplemental indenture to be given to each Holder as promptly as possible after the execution thereof in accordance with the terms of Section 12.11 of the Indenture.

(c) On or before the 30th day immediately after the Effective Time, the Surviving Corporation shall deliver to the Trustee and all Holders the notice, and shall issue the press release, required by Section 13.3(1) of the Indenture.

(d) The Company shall take all such further actions, including the delivery of the Officers’ Certificate and Opinion of Counsel (as such terms are defined in the Indenture) required by Sections 7.1(3) and 12.11 of the Indenture, as may be necessary to comply with all of the terms and conditions of the Indenture.

(a) subject to Section 6.09(b), by mutual written consent of Parent, Sub and the Company;

(b) by either Parent or the Company, if:

(i) the Offer Closing shall not have occurred prior to October 30, 2009 (the “Termination Date”) for any reason; provided, however, that the right to terminate this Agreement under this Section 8.01(b)(i) shall not be available to any party whose action or failure to act has been a principal cause of or resulted in the failure of the Offer Closing to occur prior to such date and such action or failure to act constitutes a breach of this Agreement;

(ii) any Legal Restraint that has the effect of preventing the consummation of the Offer or the Merger shall be in effect and shall have become final and nonappealable; or

(c) prior to the Offer Closing, by Parent, in the event an Adverse Recommendation Change has occurred;

(e) prior to the Offer Closing, by Parent, if (i) the Company shall have breached any of its representations or warranties or failed to perform any of its obligations, covenants or agreements contained in this Agreement, which breach or

failure to perform (A) would give rise to the failure of a condition set forth in paragraph (d) or (e) of clause (iii) of Exhibit A and (B) is incapable of being cured by the Company by the Termination Date or, if capable of being cured by the Company by the Termination Date, the Company does not commence to cure such breach or failure within ten business days after its receipt of written notice thereof from Parent and use its reasonable best efforts to pursue such cure thereafter, or (ii) if any Legal Restraint having any of the consequences referred to in clauses (2) through (4) of paragraph (a) of clause (iii) of Exhibit A shall be in effect and shall have become final and nonappealable; provided, however, that this Agreement may not be terminated pursuant to this Section 8.01(e)(ii) if Parent or Sub is then in breach of Section 6.03 of this Agreement and such breach has been a principal cause of such Legal Restraint being or remaining in effect;

(f) prior to the Offer Closing, by the Company, if (i) Parent or Sub shall have breached any of its representations or warranties contained in this Agreement or (ii) Parent or Sub shall have failed to perform all obligations, covenants or agreements required to be performed by them under this Agreement at or prior to the Offer Closing, in each case, which breach or failure to perform (A) is incapable of being cured by Parent or Sub by the Termination Date or, if capable of being cured by Parent by the Termination Date, Parent and Sub do not commence to cure such breach or failure within ten business days after their receipt of written notice thereof from the Company and use their reasonable best efforts to pursue such cure thereafter and (B) in any way would reasonably be expected to prevent, materially impede or materially delay the consummation by Parent or Sub of the Offer, the Merger or the other transactions contemplated by this Agreement;

(g) prior to the Offer Closing, (i) by Parent if, on any then-scheduled expiration date for the Offer, Sub is not required (and Parent is not required to cause Sub) to extend the Offer pursuant to the sixth sentence of Section 1.01(a) and any of the Offer Conditions shall have occurred and be continuing on such then-scheduled expiration date and (ii) by the Company, if the Offer has expired in accordance with its terms and has not been extended by Sub, and Sub has not accepted for payment within three business days following such expiration all shares of Company Common Stock validly tendered and not validly withdrawn; or

(h) by the Company in accordance with the terms and subject to the conditions of Section 5.02(b).

SECTION 8.02. Effect of Termination. In the event of termination of this Agreement by either the Company or Parent as provided in Section 8.01, this Agreement shall forthwith become void and have no effect, without any liability or obligation on the part of Parent, Sub or the Company or their respective Subsidiaries, officers or directors, except that (a) the provisions of Section 4.01(u), the last sentence of Section 6.02, Section 6.06, this Section 8.02 and Article IX shall survive such termination and (b) the termination of this Agreement shall not relieve or release any party hereto from any liability arising out of its willful breach of this Agreement or any fraud.

SECTION 8.03. Amendment. Subject to Section 6.09(b), this Agreement may be amended by the parties hereto at any time, whether before or after the Offer Closing shall have occurred or the Shareholder Approval, if required by applicable Law, has been obtained; provided, however, that (a) after the Offer Closing, there shall be no amendment that decreases the Merger Consideration and (b) after the Shareholder Approval has been obtained, there shall be made no amendment that by Law requires further approval by shareholders of the Company without the further approval of such shareholders. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

SECTION 8.04. Extension; Waiver. At any time prior to the Effective Time, the parties may, subject to Section 6.09(b), (a) extend the time for the performance of any of the obligations or other acts of the other parties, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto or (c) waive compliance with any of the agreements or conditions contained herein; provided, however, that after the Shareholder Approval has been obtained, there shall be made no waiver that by Law requires further approval by shareholders of the Company without the further approval of such shareholders. 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 which specifically sets forth the terms of such extension or waiver. The failure or delay by any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights nor shall any single or partial exercise by any party to this Agreement of any of its rights under this Agreement preclude any other or further exercise of such rights or any other rights under this Agreement.

any of its Subsidiaries except in such courts). Each of the parties further agrees that, to the fullest extent permitted by applicable Law, service of any process, summons, notice or document by U.S. registered mail to such person’s respective address set forth above shall be effective service of process for any action, suit or proceeding in the State of Delaware with respect to any matters to which it has submitted to jurisdiction as set forth above in the immediately preceding sentence. Each of the parties hereto irrevocably and unconditionally waives (and agrees not to plead or claim) any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or the transactions contemplated by this Agreement in the Delaware Court of Chancery (and if the Delaware Court of Chancery shall be unavailable, in any Delaware State court or the Federal court of the United States of America sitting in the State of Delaware) or that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.

SECTION 9.10. Waiver of Jury Trial. Each party hereto hereby waives, to the fullest extent permitted by applicable Law, any right it may have to a trial by jury in respect of any suit, action or other proceeding directly or indirectly arising out of, under or in connection with this Agreement. Each party hereto (a) certifies that no Representative of any other party has represented, expressly or otherwise, that such party would not, in the event of any action, suit or proceeding, seek to enforce the foregoing waiver and (b) acknowledges that it and the other parties hereto have been induced to enter into this Agreement, by, among other things, the mutual waiver and certifications in this Section 9.10.

SECTION 9.11. Enforcement. The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached.

SECTION 9.12. Consents and Approvals. For any matter under this Agreement requiring the consent or approval of any party to be valid and binding on the parties hereto, such consent or approval must be in writing and executed and delivered to the other parties by a person duly authorized by such party to do so.

SECTION 9.13. Severability.

(3) any representations and warranties of the Company set forth in the Agreement (other than those listed in the preceding clause (1) but including those listed in the preceding clause (2)) shall not be true and correct as of the date of the Agreement and as of such time, except to the extent such representations and warranties relate to an earlier time (in which case on and as of such earlier time), except in the case of this clause (3) to the extent that the facts or matters as to which such representations and warranties are not so true and correct (without giving effect to any qualifications and limitations as to “materiality” or “Material Adverse Effect” set forth therein), individually or in the aggregate, have not had and would not reasonably be expected to have a Material Adverse Effect; or
