AGREEMENT AND PLAN OF MERGER

This Agreement and Plan of Merger (this “Agreement”) is dated as of September 27, 2009, among United States Surgical Corporation, a Delaware corporation (the “Parent”), Transformer Delaware Corp., a Delaware corporation and a wholly owned subsidiary of the Parent (the “Purchaser”), and Aspect Medical Systems, Inc., a Delaware corporation (the “Company”).

INTRODUCTION

This Agreement contemplates the acquisition of the Company by the Parent on the terms and subject to the conditions set forth in this Agreement. The Purchaser will make a cash tender offer (as it may be amended from time to time as permitted under this Agreement, the “Offer”) to purchase all of the outstanding shares of common stock, $0.01 par value per share, of the Company (the “Company Common Stock”), at a price of $12.00 per share of Company Common Stock, net to the seller in cash, without interest thereon (such price, or any higher price as may be paid in the Offer in accordance with this Agreement, the “Offer Price”), upon the terms and subject to the conditions set forth in this Agreement. Following consummation of the Offer, the Purchaser will be merged with and into the Company, with the Company continuing as the surviving corporation in such merger (the “Merger”). As a result of the Merger, the Company will become a wholly owned subsidiary of the Parent. The Boards of Directors of each of the Purchaser and the Company have approved and declared advisable the Offer and the Merger and adopted this Agreement. The Board of Directors of the Parent has approved the Offer, the Merger and this Agreement. Concurrently with the execution and delivery of this Agreement, and as a condition and inducement to the Parent entering into this Agreement, certain Company stockholders (the “Principal Stockholders”) have entered into tender and voting agreements, dated as of the date hereof, in substantially the form set forth in Annex II, pursuant to which, among other things, each of the Principal Stockholders has agreed to tender his, her or its shares to the Purchaser in the Offer (the “Tender and Voting Agreements”);

The Parent, the Purchaser and the Company therefore agree as follows:

ARTICLE I

THE CASH TENDER OFFER

1.1 The Offer.

(a) Commencement of the Offer; Acceptance of Shares. Subject to the terms and conditions of this Agreement, as soon as reasonably practicable after the date of this Agreement, and in any event no later than the 10th day after the day on which the Purchaser’s intention to make the Offer is publicly announced (which announcement will be made by the Parent on September 28, 2009), the Purchaser shall commence (within the meaning of Rule 14d-2 under the Securities Exchange Act of 1934 (the “Exchange Act”)) the Offer to purchase any and all outstanding shares of Company Common Stock at a price equal to the Offer Price. For purposes of this Agreement, a “Business Day” shall be any day on which the principal offices of the SEC in Washington, DC are open to accept filings other than a day on which banking

institutions located in Boston, Massachusetts are permitted or required by Law to remain closed. Within one Business Day of the later of: (i) the earliest date as of which the Purchaser is permitted under the Exchange Act to accept for payment shares of Company Common Stock validly tendered (and not validly withdrawn) pursuant to the Offer and (ii) the earliest date as of which each of the conditions set forth in Annex I (the “Offer Conditions”) shall have been satisfied or waived, the Purchaser shall (and the Parent shall cause the Purchaser to) accept for payment all shares of Company Common Stock validly tendered (and not validly withdrawn) pursuant to the Offer. The obligation of the Purchaser to accept for payment shares of Company Common Stock validly tendered (and not validly withdrawn) pursuant to the Offer shall be subject only to the satisfaction or waiver of each of the Offer Conditions (and shall not be subject to any other conditions). The Purchaser shall promptly pay (in accordance with Rule 14e-1 under the Exchange Act) for all shares of Company Common Stock validly tendered (and not validly withdrawn) in the Offer.

(b) Expiration Date; Extensions and Amendment. The initial expiration date of the Offer shall be either the 20th or 21st Business Day after commencement of the Offer (determined in accordance with Rules 14d-1(g)(3) and 14d-2 under the Exchange Act). The Parent and the Purchaser expressly reserve the right to increase the Offer Price and, subject to the immediately succeeding sentence, reserve the right to waive, amend, modify or supplement any of the Offer Conditions or other terms of the Offer. Notwithstanding anything to the contrary contained in this Agreement, neither the Parent nor the Purchaser shall (without the prior written consent of the Company):

(i) change the form of consideration payable in the Offer, decrease the Offer Price or change the Offer so that it is for fewer than all of the outstanding shares of Company Common Stock;

(ii) extend or otherwise change the expiration date of the Offer, except (A) as required by applicable Law (including for any period required by any rule, regulation, interpretation or position of the United States Securities and Exchange Commission (the “SEC”)) or (B) in connection with an increase in the consideration to be paid pursuant to the Offer so as to comply with applicable rules, regulations, interpretations or positions of the SEC;

(iii) change or waive the Minimum Condition;

(iv) amend, modify or supplement any of the Offer Conditions or the terms of the Offer in any manner adverse to holders of shares of Company Common Stock or that would, individually or in the aggregate, reasonably be expected to prevent the consummation of the Offer or prevent or impair the ability of the Parent or the Purchaser to consummate the Offer, the Merger or the other transactions contemplated by this Agreement; or

(v) impose any condition to the Offer other than the Offer Conditions.

If, at any time when the Offer is scheduled to expire, any of the Offer Conditions have not been satisfied (and the Parent or the Purchaser has not waived such condition in accordance with the terms of this Agreement), the Purchaser shall, at the request of the Company at least one Business Day before the then-scheduled expiration date, and may, without the consent of the

- 2 -

Company, (x) extend the expiration date of the Offer for up to two periods of not more than 10 Business Days each but in no event later than the Outside Date. The Offer may be terminated prior to its expiration date (as such expiration date may be extended and re-extended in accordance with this Agreement) only if this Agreement is validly terminated in accordance with Article VIII.

(i) The Purchaser may, without the consent of the Company, elect to provide a subsequent offering period (not in excess of 10 Business Days) for the Offer in accordance with Rule 14d-11 under the Exchange Act following its acceptance for payment of shares of Company Common Stock in the Offer.

(ii) Subject to the terms and conditions set forth in this Agreement and the Offer, the Parent shall cause the Purchaser to, and the Purchaser shall, accept for payment and pay for all shares of Company Common Stock validly tendered during such subsequent offering period promptly after any such shares of Company Common Stock are tendered during any subsequent offering period in compliance with Rule 14d-11(c) promulgated under the Exchange Act.

(d) Schedule TO and Offer Documents. On the date of commencement of the Offer, the Parent and the Purchaser shall file with the SEC a Tender Offer Statement on Schedule TO (together with all amendments and supplements thereto, the “Schedule TO”) with respect to the Offer. The Schedule TO shall contain an offer to purchase and a form of the related letter of transmittal, the forms of which shall be reasonably acceptable to the Company, and ancillary documents and instruments pursuant to which the Offer will be made (collectively, together with any supplements or amendments thereto, the “Offer Documents”). The Parent and the Purchaser shall cause the Offer Documents (i) to comply in all material respects with the requirements of applicable U.S. federal securities Laws and (ii) on the date first filed with the SEC and on each date published, sent or given to the holders of shares of Company Common Stock, not to 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 were made, not misleading, except that no covenant is made by the Parent or the Purchaser with respect to information supplied by the Company or any of its stockholders in writing specifically for inclusion in the Offer Documents. Subject to the Company’s compliance with Section 1.2(e), the Parent and the Purchaser shall take all steps necessary to cause the Offer Documents to be disseminated to holders of shares of Company Common Stock, as and to the extent required by applicable U.S. federal securities Laws. Each of the Parent, the Purchaser and the Company shall promptly correct any information provided by it for use in the Schedule TO or the other Offer Documents if and to the extent that such information shall have become false or misleading in any material respect or as otherwise required by applicable Law, and the Parent and the Purchaser shall take all steps necessary to amend or supplement the Schedule TO and, as applicable, the other Offer Documents and to cause the Schedule TO as so amended and supplemented to be filed with the SEC and the other Offer Documents as so amended and supplemented to be disseminated to holders of shares of Company Common Stock, in each case as and to the extent required by applicable U.S. federal securities Laws. The Company and its counsel shall be given reasonable opportunity to review and comment upon the Offer Documents

- 3 -

and any amendments thereto prior to the filing thereof with the SEC or dissemination to the holders of shares of Company Common Stock. The Parent and the Purchaser shall provide the Company and its counsel with a copy of any written comments or telephonic or email notification of any oral comments the Parent, the Purchaser or their counsel may receive from the SEC with respect to the Offer promptly after the receipt thereof, shall consult with the Company and its counsel prior to responding to any such comments, and shall provide the Company and its counsel with a copy of any written responses thereto and telephonic or email notification of any oral responses thereto of the Parent or the Purchaser or their counsel.

(e) Provisions of Funds by the Parent. The Parent shall provide or cause to be provided to the Purchaser on a timely basis the funds necessary to purchase any and all shares of Company Common Stock that the Purchaser becomes obligated to purchase pursuant to the Offer.

(f) Termination of Offer and Return of Tendered Shares. Unless this Agreement is terminated pursuant to Section 8.1, the Purchaser shall not terminate or withdraw the Offer prior to any scheduled expiration date without the prior written consent of the Company in its sole and absolute discretion. In the event this Agreement is terminated pursuant to Section 8.1, the Purchaser shall promptly (and in any event within one Business Day) following such termination irrevocably and unconditionally terminate the Offer and shall not acquire any shares of Company Common Stock pursuant thereto. If the Offer is terminated in accordance with this Agreement prior to the purchase of shares of Company Common Stock in the Offer, the Purchaser shall promptly return, or cause any depositary acting on behalf of the Purchaser to return, all tendered shares of Company Common Stock to the tendering stockholders.

(g) Adjustments to Offer Price. The Offer Price shall be adjusted to reflect fully the effect of any reclassification, stock split, reverse split, stock dividend (including any dividend or distribution of securities convertible into Company Common Stock), reorganization, recapitalization or other like change with respect to Company Common Stock occurring (or for which a record date is established) after the date hereof and prior to the payment by the Purchaser for the shares of Company Common Stock validly tendered (and not validly withdrawn) in the Offer.

(h) Tax Withholding. The Parent, the Purchaser or the Paying Agent, as applicable, shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to the Offer any transfer tax due and any other amounts as the Parent, the Purchaser or the Paying Agent, as applicable, are 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 under any other applicable state, local or non-U.S. Tax Law. To the extent that amounts are so withheld by the Parent, the Purchaser or the Paying Agent, such withheld amounts (i) shall be remitted by the Parent, the Purchaser or the Paying Agent to the applicable Governmental Entity and (ii) 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 the Parent, the Purchaser or the Paying Agent, as the case may be.

(b) Schedule 14D-9. As soon as reasonably practicable after the date of this Agreement, and in any event no later than the 10th day after the day on which the Purchaser’s intention to make the Offer is publicly announced, the Company shall file with the SEC a Solicitation/Recommendation Statement on Schedule 14D-9 with respect to the Offer (together with all amendments and supplements thereto, the “Schedule 14D-9”) and disseminate the Schedule 14D-9, to the extent required by Rule 14d-9 promulgated under the Exchange Act and any other applicable Laws, to the holders of shares of Company Common Stock. Except as required by applicable Law or as otherwise permitted pursuant to Section 6.1 below, the Offer Documents and the Schedule 14D-9 shall contain the recommendation of the Board of Directors of the Company (together with any duly constituted and authorized committee thereof, the “Company Board”) referred to in Section 3.4(a), and the Company hereby consents to the inclusion in the Offer Documents of such recommendation. The Company shall cause the Schedule 14D-9 (i) to comply in all material respects with the requirements of applicable U.S. federal securities and Delaware corporation Laws, and include a copy of the written fairness opinion, dated as of the date of this Agreement, rendered by Goldman Sachs & Co. to the Company Board in its entirety and a fair summary of the material financial analyses presented by Goldman Sachs & Co. to the Company Board in connection with the rendering of such fairness opinion, and (ii) on the date first filed with the SEC and on the date first published, sent or given to the holders of shares of Company Common Stock, not to 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 were made, not misleading, except that no covenant is made by the Company with respect to information supplied by the Parent or the Purchaser in writing specifically for inclusion in the Schedule 14D-9. Each of the Company, the Parent and the Purchaser shall promptly correct any information provided by it for use in the Schedule 14D-9 if and to the extent that such information shall have become false or misleading in any material respect or as otherwise required by applicable Law, 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 holders of shares of Company Common Stock, in each case as and to the extent required by applicable U.S. federal securities and Delaware corporation Laws. Each member of the Board of Directors and each executive officer of the Company has advised the Company that, as of the date hereof, his or her current intention is to tender all shares of Company Common Stock, if any, owned by him or her in the Offer.

(i) The Parent and its counsel shall be given reasonable opportunity to review and comment upon the Schedule 14D-9 and any amendments thereto prior to the filing thereof with the SEC or dissemination to holders of shares of Company Common Stock.

- 5 -

(ii) The Company shall provide the Parent and its counsel with a copy of any written comments or telephonic or email notification of any oral comments the Company or its counsel may receive from the SEC with respect to the Offer promptly after the receipt thereof, shall consult with the Parent and its counsel prior to responding to any such comments, and shall provide the Parent and its counsel with a copy of any written responses thereto and telephonic or email notification of any oral responses thereto of the Company or its counsel.

(d) Provision of Information for Offer Documents. The Company shall promptly supply to the Parent and the Purchaser in writing, for inclusion in the Offer Documents, all information concerning the Company required under applicable U.S. federal securities Laws to be included in the Offer Documents or that may be reasonably requested by the Parent and the Purchaser in connection with the preparation of the Offer Documents.

(e) Stockholder Lists. In connection with the Offer and the Merger, the Company shall instruct its transfer agent to promptly furnish to the Purchaser or its designated agent mailing labels, security position listings and all other available listings and computer files containing the names and addresses of the record holders of the shares of Company Common Stock as of a recent date and, to the extent known, a list of the beneficial owners of the shares of Company Common Stock as of a recent date and of those persons becoming record or beneficial holders subsequent to such date, and shall promptly furnish to the Purchaser such information and assistance as the Purchaser may reasonably request for the purpose of communicating the Offer to the holders of shares of Company Common Stock. Subject to the requirements of applicable Laws and except for such steps as are necessary to disseminate the Offer Documents and any other documents necessary to consummate the Offer, the Merger and the other transactions contemplated by this Agreement, the Parent and the Purchaser shall, until consummation of the Offer, hold in confidence the information contained in any of such labels and lists in accordance with the Confidentiality Agreement, shall use such information only in connection with the Offer, the Merger and the other transactions contemplated by this Agreement and, if this Agreement shall be terminated in accordance with Section 8.1, shall destroy all electronic copies of such information and deliver to the Company all other copies of such information then in their possession or under their control.

1.3 Directors.

(a) Election of the Purchaser Designees. After the first time at which the Purchaser accepts for payment, and pays for, shares of Company Common Stock pursuant to the Offer satisfying the Minimum Condition (the “Acceptance Time”), and from time to time thereafter as shares of Company Common Stock are accepted for payment and paid for by the Purchaser, the Purchaser shall be entitled to designate such number of members of the Company Board (the “Purchaser Designees”), rounded up to the nearest whole number, as will give the Purchaser representation on the Company Board equal to the product of the total number of members of the Company Board (after giving effect to the directors elected, appointed or designated pursuant to this sentence) multiplied by the percentage that the number of shares of Company Common Stock beneficially owned by the Parent or the Purchaser at such time (including shares of Company Common Stock so accepted for payment) bears to the total number of shares of Company Common Stock then outstanding (determined on a fully diluted basis). In furtherance thereof, the Company shall, upon the request of the Purchaser, use its

- 6 -

commercially reasonable efforts promptly either to increase the size of the Company Board or to secure the resignations of such number of the Company’s incumbent directors, or both, as is necessary to enable the Purchaser Designees to be so elected or appointed to the Company Board and the Company shall take all reasonable actions available to the Company to cause the Purchaser Designees to be so elected or appointed. At such time, the Company shall, if requested by the Purchaser, also take all reasonable action necessary to cause persons designated by the Purchaser to constitute at least the same percentage (rounded up to the next whole number) as is on the Company Board of (i) each committee of the Company Board (other than any committee of the Company Board established to take action under this Agreement), (ii) each board of directors (or similar body) of each Subsidiary of the Company and (iii) each committee (or similar body) of each such board of directors.

(b) Compliance with Section 14(f) and Rule 14f-1. The Company’s obligations in Section 1.3(a) shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder and to the applicable rules and regulations of The Nasdaq Stock Market. The Company shall take all actions required in order to fulfill its obligations under Section 1.3(a), including mailing to holders of shares of Company Common Stock the information required by Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder as part of the Schedule 14D-9; provided, that (i) the Parent and the Purchaser shall have timely supplied to the Company in writing any information with respect to the Parent, the Purchaser and the Purchaser Designees to the extent required by such Section 14(f) and Rule 14f-1 and (ii) the Parent shall be solely responsible for the accuracy of any such information provided by the Parent.

(c) Continuing Directors. Notwithstanding the foregoing provisions of this Section 1.3, the parties hereto shall use their respective best efforts to ensure that at least two of the members of the Company Board shall, at all times prior to the Effective Time (as defined below), be directors of the Company who were directors of the Company on the date hereof and who are not officers of the Company (the “Continuing Directors”), provided that, if there shall be in office fewer than two Continuing Directors for any reason, the Company Board shall cause the person designated by the remaining Continuing Director to be appointed to fill such vacancy, and such person shall be deemed to be a Continuing Director for all purposes of this Agreement, or if no Continuing Directors then remain, the other directors of the Company then in office shall designate two persons to fill such vacancies who are not directors, officers, employees or Affiliates of the Parent or the Purchaser and are “independent directors” of the Company for purposes of Nasdaq Marketplace Rule 5605(a)(2) as in effect on the date hereof, and such Persons shall be deemed to be Continuing Directors for all purposes of this Agreement. From and after the time, if any, that the Purchaser Designees constitute a majority of the Company Board and prior to the Effective Time, subject to the terms hereof, any (i) amendment or modification of this Agreement, (ii) termination of this Agreement by the Company, (iii) extension of time for performance of any of the obligations of the Parent or the Purchaser hereunder, (iv) waiver of any condition to the Company’s obligations hereunder, (v) exercise or waiver of the Company’s rights or remedies hereunder, (vi) amendment to the Company’s certificate of incorporation or bylaws, (vii) authorization of any agreement between the Company and any of its Subsidiaries, on the one hand, and the Parent, the Purchaser or any of their Affiliates on the other hand, or (viii) taking of any other action by the Company in connection with this Agreement or the transactions contemplated hereby required to be taken by

- 7 -

the Company Board may be effected only if there are in office one or more Continuing Directors and such action is approved by a majority of the Continuing Directors then in office. The Continuing Directors shall have, and the Parent shall cause the Continuing Directors to have, the authority to retain such counsel (which may include current counsel to the Company) and other advisors (which may include current advisors to the Company) at the expense of the Company as determined by the Continuing Directors, and the authority to institute any action on behalf of the Company to enforce performance of this Agreement.

2.1 The Merger. Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the General Corporation Law of the State of Delaware (the “DGCL”), the Purchaser shall merge with and into the Company at the Effective Time.

2.2 Effective Time of the Merger. Subject to the provisions of this Agreement, prior to the Closing, the Parent shall prepare, and immediately following the Closing the Company shall cause to be filed with the Secretary of State of the State of Delaware (the “Secretary of State”), a certificate of merger or a certificate of ownership and merger, as the case may be (the “Certificate of Merger”), in such form as is required by, and executed by the Company or the Purchaser, as the case may be, in accordance with, the relevant provisions of the DGCL, and shall make all other filings or recordings required under the DGCL. The Merger shall become effective upon the due filing of the Certificate of Merger with the Secretary of State or at such later time as is established by the Parent and the Company and set forth in the Certificate of Merger (the “Effective Time”).

2.3 Closing. The closing of the Merger (the “Closing”) shall take place at 10:00 a.m., Eastern time, on a date to be specified by the Parent and the Company (the “Closing Date”), which shall be no later than the second Business Day after satisfaction or waiver of the conditions set forth in Article VII (other than delivery of items to be delivered at the Closing and other than satisfaction of those conditions that by their nature are to be satisfied at the Closing, it being understood that the occurrence of the Closing shall remain subject to the delivery of such items and the satisfaction or waiver of such conditions at the Closing), at the offices of Ropes & Gray, One International Place, Boston, Massachusetts, unless another date, place or time is agreed to in writing by the Parent and the Company.

2.4 Effects of the Merger. At the Effective Time (a) the separate existence of the Purchaser shall cease and the Purchaser shall be merged with and into the Company (the Company following the Merger is sometimes referred to herein as the “Surviving Corporation”) and (b) the certificate of incorporation of the Company as in effect immediately prior to the Acceptance Time shall be amended in its entirety to read as set forth on Exhibit A, until further amended in accordance with the DGCL. In addition, subject to Section 6.7(b) hereof, the Parent shall cause the bylaws of the Surviving Corporation to be amended and restated in their entirety so that, immediately following the Effective Time, they are identical to the bylaws of the Purchaser as in effect immediately prior to the Effective Time, except that all references to the name of the Purchaser therein shall be changed to refer to the

- 8 -

name of the Company, and, as so amended and restated, such bylaws shall be the bylaws of the Surviving Corporation, until further amended in accordance with the DGCL. The Merger shall have the effects set forth in Section 259 of the DGCL.

2.5 Directors of the Surviving Corporation. The directors of the Purchaser immediately prior to the Effective Time shall be the initial directors of the Surviving Corporation, and the officers of Purchaser immediately prior to the Effective Time shall be the initial officers of the Surviving Corporation, in each case to hold office in accordance with the certificate of incorporation and bylaws of the Surviving Corporation. Prior to the Effective Time, the Company shall cause each member of the Company Board of Directors, other than the Purchaser Designees, to execute and deliver a letter effectuating his or her resignation as a director of the Company upon the Effective Time.

2.6 Top-Up Option.

(a) Subject to Section 2.6(b) and Section 2.6(c), the Company grants to the Purchaser an option (the “Top-Up Option”) to purchase from the Company the number of shares of Company Common Stock (the “Top-Up Option Shares”) equal to the number of shares of Company Common Stock that, when added to the number of shares of Company Common Stock owned by the Parent, the Purchaser and their respective Affiliates as of immediately prior to the exercise of the Top-Up Option, constitutes one share more than 90% of the number of shares of Company Common Stock then outstanding (assuming the issuance of the Top-Up Option Shares); provided, however, that in no event shall the Top-Up Option be exercisable for a number of shares in excess of the aggregate of the number of shares of Company Common Stock held as treasury shares by the Company or by its Subsidiaries and the number of shares of Company Common Stock that the Company is authorized to issue under its certificate of incorporation but that are not issued and outstanding (and are not otherwise reserved for issuance to satisfy outstanding rights to acquire shares of Company Common Stock) as of immediately prior to the exercise of the Top-Up Option.

(b) The Top-Up Option may be exercised by the Purchaser, in whole but not in part, at any time at or after the Acceptance Time and the expiration of any subsequent offering period and on or prior to the fifth Business Day after the later of (i) the expiration date of the Offer or (ii) the expiration of any subsequent offering period; provided, however, that the obligation of the Company to deliver Top-Up Option Shares upon the exercise of the Top-Up Option is subject to the conditions, unless waived by the Company, that (A) no provision of any applicable Law, and no temporary restraining order, preliminary or permanent injunction or other judgment or order issued by a court of competent jurisdiction or other Governmental Entity of competent jurisdiction, shall prohibit the exercise of the Top-Up Option or the delivery of the Top-Up Option Shares in respect of such exercise, (B) the issuance of Top-Up Option Shares pursuant to the Top-Up Option would not require approval of the Company’s stockholders under applicable Law, (C) upon exercise of the Top-Up Option, the number of shares of Company Common Stock owned by the Parent, the Purchaser and their respective Affiliates constitutes one share more than 90% of the number of shares of Company Common Stock that will be outstanding immediately after the issuance of the Top-Up Option Shares, (D) the Purchaser has accepted for payment and paid for all shares of Company Common Stock validly tendered in the Offer and not withdrawn and (E) the Minimum Condition shall have been satisfied; and,

- 9 -

provided, further, that the Top-Up Option shall terminate concurrently with the termination of this Agreement. The Purchaser shall exercise the Top-Up Option if doing so would be lawful and would allow it to consummate the Merger pursuant to Section 253 of the DGCL. The parties hereto shall cooperate to ensure that the issuance of the Top-Up Option Shares is accomplished in a manner consistent with all applicable Laws, including compliance with an applicable exemption from registration of the Top-Up Option Shares under the Securities Act. The aggregate purchase price payable for the Top-Up Option Shares shall be determined by multiplying the number of such Top-Up Option Shares by the Offer Price. Such purchase price shall be paid by the Purchaser (x) in cash or (y) by delivering Parent’s promissory note in the principal amount of the balance of such purchase price, which promissory shall be on terms reasonably satisfactory to the Company.

(c) In the event that the Purchaser wishes to exercise the Top-Up Option, it shall deliver to the Company a notice setting forth the place and time at which the closing of the purchase of the Top-Up Option Shares by the Purchaser is to take place. At the closing of the purchase of the Top-Up Option Shares, the Purchaser shall cause to be delivered to the Company the consideration required to be delivered in exchange for such Top-Up Option Shares, and the Company shall cause such Top-Up Option Shares to be issued to the Purchaser via book-entry delivery. The Purchaser shall consummate the Merger pursuant to Section 253 of the DGCL promptly (and in any event within one Business Day) following the closing of the purchase of the Top-Up Option Shares.

(d) The Parent and the Purchaser acknowledge that the Top-Up Option Shares that the Purchaser may acquire upon exercise of the Top-Up Option will not be registered under the Securities Act of 1933 (the “Securities Act”), and will be issued in reliance upon an exemption thereunder for transactions not involving a public offering. The Parent and the Purchaser represent and warrant to the Company that the Purchaser is, or will be upon the purchase of the Top-Up Option Shares, an “accredited investor,” as defined in Rule 501 of Regulation D under the Securities Act. The Purchaser agrees that the Top-Up Option and the Top-Up Option Shares to be acquired upon exercise of the Top-Up Option are being and will be acquired by the Purchaser for the purpose of investment and not with a view to, or for resale in connection with, any distribution thereof in violation of the Securities Act.

2.7 Conversion of Capital Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of the capital stock of the Company or capital stock of the Purchaser:

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

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

- 10 -

(c) Merger Consideration for Company Common Stock. Subject to Section 2.8, each share of Company Common Stock (other than shares to be cancelled in accordance with Section 2.7(b) and Dissenting Shares (as defined in Section 2.10(a) below)) issued and outstanding immediately prior to the Effective Time shall be automatically converted into the right to receive the Offer Price (the “Merger Consideration”). As of the Effective Time, all such shares of Company Common Stock shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each holder of (i) a certificate which immediately prior to the Effective Time represented any such shares of Company Common Stock (each, a “Certificate”) and (ii) uncertificated shares which immediately prior to the Effective Time represented any such shares of Company Common Stock (the “Uncertificated Shares”) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration pursuant to this Section 2.7(c) in accordance with the provisions of Section 2.8.

(d) Adjustments to Merger Consideration. The Merger Consideration shall be adjusted to reflect fully the effect of any reclassification, stock split, reverse split, stock dividend (including any dividend or distribution of securities convertible into Company Common Stock), reorganization, recapitalization or other like change with respect to Company Common Stock occurring (or for which a record date is established) after the date hereof and prior to the Effective Time.

2.8 Surrender of Certificates.

(a) Paying Agent. At or prior to the Effective Time, the Parent shall deposit with Computershare Trust Company, N.A. or another bank or trust company appointed by the Parent and reasonably acceptable to the Company (the “Paying Agent”), for the benefit of the holders of shares of Company Common Stock outstanding immediately prior to the Effective Time, for payment through the Paying Agent in accordance with this Section 2.8, cash in an amount sufficient to make payment of the Merger Consideration pursuant to Section 2.7(c) in exchange for all of the outstanding shares of Company Common Stock (the “Payment Fund”). The Payment Fund shall not be used for any other purpose. The Payment Fund shall be invested by the Paying Agent as directed by the Parent; provided, however, that such investments shall be in obligations of or guaranteed by the United States of America, in commercial paper obligations rated A-1 or P-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation, respectively, or in certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks rated A-1 or P-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation, respectively; provided, however, that no gain or loss thereon shall affect the amounts payable hereunder and the Parent shall take all actions necessary to ensure that the Payment Fund includes at all times cash sufficient to satisfy the Parent’s obligation to pay the Merger Consideration under this Agreement. Any interest and other income resulting from such investments (net of any losses) shall be the property of the Parent. In the event of any losses to the Payment Fund from any investment such that the Payment Fund is diminished below the level required for the Paying Agent to make prompt cash payments as required under Section 2.8(b), the Parent shall, or shall cause the Surviving Corporation to, immediately deposit additional cash into the Payment Fund to the extent necessary to satisfy such obligations.

- 11 -

(b) Exchange Procedures. Promptly (and in any event within five Business Days) after the Effective Time, the Parent shall cause the Paying Agent to mail to each holder of record of a Certificate and each holder of record of Uncertificated Shares (i) a letter of transmittal in customary form (which shall specify that delivery shall be effected, and risk of loss and title to the Certificate or Uncertificated Shares shall pass, only upon delivery of the Certificates or Uncertificated Shares to the Paying Agent and shall be in such form and have such other provisions as Parent may reasonably specify) and (ii) in the case of a holder of Certificates, instructions for effecting the surrender of the Certificates in exchange for the Merger Consideration payable with respect thereto. Upon surrender of a Certificate for cancellation to the Paying Agent, together with such letter of transmittal, duly executed and completed, the holder of such Certificate shall be paid promptly in exchange therefor cash in an amount equal to the Merger Consideration that such holder has the right to receive pursuant to the provisions of this Article II, and the Certificate so surrendered shall immediately be cancelled. Upon receipt of an “agent’s message” by the Paying Agent (or such other evidence, if any, of transfer as the Paying Agent may reasonably request) in the case of a book-entry transfer of Uncertificated Shares, the holders of such Uncertificated Shares shall be paid promptly in exchange therefor cash in an amount equal to the Merger Consideration that such holder has the right to receive pursuant to the provisions of this Article II, and the transferred Uncertificated Shares so surrendered shall forthwith be canceled.

(c) No interest will be paid or accrued on the cash payable upon the surrender of such Certificates or Uncertificated Shares. In the event of a transfer of ownership of Company Common Stock or Uncertificated Shares which is not registered in the transfer records of the Company, the Merger Consideration may be paid to a Person other than the Person in whose name the Certificate or Uncertificated Shares is registered, if, in the case of a Certificate, such Certificate is presented to the Paying Agent, and in each case the transferor provides to Paying Agent (i) all documents required to evidence and effect such transfer and (ii) evidence that any applicable stock transfer taxes have been paid. Until surrendered as contemplated by this Section 2.8, each Certificate and all Uncertificated Shares (other than Certificates or Uncertificated Shares representing Dissenting Shares) shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration as contemplated by this Section 2.8. As used in this Agreement, “Person” means any individual, corporation, partnership, limited liability company, joint venture, association, trust, Governmental Entity, unincorporated organization or other entity.

(d) No Further Ownership Rights in Company Common Stock. All Merger Consideration paid upon the surrender of Certificates and cancellation of Uncertificated Shares in accordance with the terms hereof shall be deemed to have been paid in satisfaction of all rights pertaining to the shares of Company Common Stock formerly represented by such Certificates and Uncertificated Shares, and from and after the Effective Time there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates or Uncertificated Shares are presented to the Surviving Corporation or the Paying Agent for any reason, they shall be cancelled and exchanged as provided in this Article II, subject to Section 2.8(e).

- 12 -

(e) Termination of Payment Fund. Any portion of the Payment Fund which remains undistributed to the holders of Certificates and Uncertificated Shares for one year after the Effective Time (including all interest and other income received by the Paying Agent in respect of all funds made available to it) shall be delivered to the Surviving Corporation, upon demand, and any holder of a Certificate or Uncertificated Shares who has not previously complied with this Section 2.8 shall be entitled to receive only from the Parent or the Surviving Corporation (subject to abandoned property, escheat and other similar laws) payment of its claim for Merger Consideration, without interest, and thereafter such holders shall be entitled to look only to the Parent or the Surviving Corporation (subject to abandoned property, escheat or other similar Laws) only as general creditors thereof with respect to the Merger Consideration payable upon due surrender of their Certificates or Uncertificated Shares, without any interest thereon.

(f) No Liability. To the extent permitted by applicable Law, none of the Parent, the Purchaser, the Company, the Surviving Corporation or the Paying Agent shall be liable to any holder of shares of Company Common Stock for any amount required to be delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If Certificates or Uncertificated Shares are not surrendered prior to two years after the Effective Time, unclaimed Merger Consideration payable with respect to such Shares 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.

(g) Withholding Rights. Each of the Parent, the Surviving Corporation and the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock, Company Stock Options or Dissenting Shares such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any other applicable state, local or non-U.S. Tax Law. To the extent that amounts are so withheld by the Surviving Corporation, the Parent or the Paying Agent, as the case may be, such withheld amounts (i) shall be remitted by the Parent, the Surviving Corporation or the Paying Agent, as the case may be, to the applicable Governmental Entity and (ii) shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock, Company Stock Options or Dissenting Shares in respect of which such deduction and withholding was made by the Surviving Corporation, the Parent or the Paying Agent, as the case may be.

(h) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if reasonably required by the Parent, the posting by such Person of a bond in such reasonable amount as the Parent may direct as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Paying Agent shall pay, in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration to be paid in respect of the shares of Company Common Stock formerly represented thereby pursuant to this Agreement.

2.9 Company Stock Plans.

(a) Each option to purchase Company Common Stock (“Company Stock Options”) granted under any stock option plans or other equity-related plans of the Company (the “Company Stock Plans”), whether vested or unvested, that is outstanding immediately prior to the Effective Time shall become fully vested and be cancelled as of immediately prior to the Effective Time (without regard to the exercise price of such Company Stock Option) in exchange for the right to receive at the Effective Time, in accordance with this Section 2.9, a lump sum cash payment in the amount of the Option Consideration (as defined below), if any, with respect to such Company Stock Option.

(b) Each holder of a Company Stock Option shall receive from the Purchaser or the Parent, in respect and in consideration of each Company Stock Option so cancelled, promptly following the Effective Time (but in any event not later than 10 Business Days), an amount (net of applicable taxes) equal to the product of (i) the excess, if any, of (A) the Merger Consideration per share of Company Common Stock over (B) the exercise price per share of Company Common Stock subject to such Company Stock Option, multiplied by (ii) the total number of shares of Company Common Stock subject to such Company Stock Option (whether or not then vested or exercisable), without any interest thereon (the “Option Consideration”). In the event that the exercise price of any Company Stock Option is equal to or greater than the Merger Consideration, such Company Stock Option shall be cancelled, without any consideration being payable in respect thereof, and have no further force or effect.

(c) As soon as practicable following the execution of this Agreement, the Company shall mail to each Person who is a holder of Company Stock Options a letter describing the treatment of and payment for such Company Stock Options pursuant to this Section 2.9 and providing instructions for use in obtaining payment for such Company Stock Options, which letter shall be subject to the Parent’s prior review and comment. The Parent shall at all times from and after the Effective Time maintain sufficient liquid funds to satisfy its obligations to holders of Company Stock Options pursuant to this Section 2.9.

(d) Each Restricted Share granted pursuant to the Company Stock Plans outstanding immediately prior to the Effective Time shall become fully vested and free of any vesting or other lapse restrictions immediately prior to the Effective Time.

(e) If the Effective Time occurs on or before the “Exercise Date” relating to the applicable “Plan Period” in effect as of the date of this Agreement (as such terms are defined in the Company ESPP) and there are “Options” (as defined in the Company ESPP) then outstanding with respect to such Plan Period, the Company Board shall, prior to such Effective Time, take such actions as are necessary to provide that all outstanding Options shall be cancelled as of the Closing Date, provided that notice of such cancellation shall be given to each holder of an Option, and to the extent that such holder does not elect to withdraw his or her participation in the Company ESPP prior to the Effective Time, then such Option shall be deemed to have been exercised in full on the Closing Date based on payroll deductions then credited to his or her account as of a date determined by the Company Board, which date shall not be less than ten (10) days preceding the Closing Date. The Company Board shall terminate the Company ESPP prior to the Effective Time. No new “Plan Period” shall commence after the date of this Agreement. As used in this Agreement, “Company ESPP” means the Company’s Restated 1999 Employee Stock Purchase Plan.

- 14 -

(f) As of the Effective Time, the Company Stock Plans shall terminate and all rights under any provision of any other plan, program or arrangement providing for the issuance or grant of any other interest in respect of the capital stock of the Company or any Subsidiary of the Company shall be cancelled.

2.10 Dissenting Shares.

(a) Notwithstanding anything to the contrary contained in this Agreement, shares of Company Common Stock issued and outstanding immediately prior to the Effective Time that are held by a holder who has not voted in favor of the Merger or consented thereto in writing and who has made a proper demand for appraisal of such shares of Company Common Stock in accordance with Section 262 of the DGCL (any such shares being referred to as “Dissenting Shares” until such time as such holder fails to perfect or otherwise loses such holder’s appraisal rights under the DGCL with respect to such shares) shall not be converted into or represent the right to receive the Merger Consideration in accordance with Section 2.7, but shall be entitled only to such rights as are granted by the DGCL to a holder of Dissenting Shares.

(b) If any Dissenting Shares shall lose their status as such (through failure to perfect or otherwise), then, as of the later of the Effective Time or the date of loss of such status, such shares shall automatically be converted into and shall represent only the right to receive the Merger Consideration in accordance with Section 2.7, without interest thereon, upon surrender of the Certificate or Uncertificated Shares formerly representing such shares.

(c) The Company shall give the Parent: (i) prompt written notice of any written demand for appraisal received by the Company prior to the Effective Time (including a copy of such demand), any withdrawal of any such demand and any other demand, notice or instrument delivered to the Company prior to the Effective Time that relate to a demand; and (ii) the opportunity to participate in all negotiations and proceedings with respect to any such demand, notice or instrument. The Company shall not settle or make any payment or settlement offer with respect to any such demand, notice or instrument unless the Parent shall have given its written consent to such settlement, payment or settlement offer.

For purposes of this Agreement, the term “Company Material Adverse Effect” means any change, event, circumstance, effect or development (each, an “Effect”) that, individually or in the aggregate with all other Effects that exist on the date of determination of the occurrence of a Company Material Adverse Effect, has had a materially adverse effect on (i) the business, financial condition or results of operations of the Company and its Subsidiaries, taken as a whole, or (ii) the ability of the Company to consummate the transactions contemplated by this Agreement; provided, however, that no Effect (by itself or when aggregated or taken together with any and all other Effects) resulting from any of the following shall be deemed to be or constitute a “Company Material Adverse Effect,” or shall be taken into account when determining whether a “Company Material Adverse Effect” has occurred or may, would or could occur:

(a) general economic conditions (or changes in such conditions) in the United States or any other country or region in the world, or conditions in the global economy generally;

(b) conditions (or changes in such conditions) in the securities markets, credit markets, currency markets or other financial markets in the United States or any other country or region in the world, including (i) changes in interest rates in the United States or any other country or region in the world and changes in exchange rates for the currencies of any countries and (ii) any suspension of trading in securities (whether equity, debt, derivative or hybrid securities) generally on any securities exchange or over-the-counter market operating in the United States or any other country or region in the world;

(h) changes in law or other legal or regulatory conditions (or the interpretation thereof) or changes in GAAP or other accounting standards (or the interpretation thereof);

- 16 -

(i) changes in the Company’s stock price or the trading volume of the Company’s stock, or any failure by the Company to meet any public estimates or expectations of the Company’s revenue, earnings or other financial performance or results of operations for any period, or any failure by the Company to meet any internal budgets, plans or forecasts of its revenues, earnings or other financial performance or results of operations (it being understood that the underlying facts or circumstances giving rise to any such change may be taken into account in determining whether there has occurred or may, would or could occur a Company Material Adverse Effect if such facts and circumstances are not otherwise excluded from this definition);

except to the extent such Effects resulting from the matters described in clauses (a) through (e) and (h) disproportionately adversely affect in a material respect the Company and its Subsidiaries, taken as a whole, as compared to other companies that conduct business in the countries and regions in the world and in the industries in which the Company and its Subsidiaries conduct business.

ARTICLE VI

ADDITIONAL AGREEMENTS

6.1 No Solicitation.

(a) No Solicitation or Negotiation. Except as set forth in this Section 6.1, until the termination of this Agreement in accordance with the terms hereof (the “Specified Time”), neither the Company nor any of its Subsidiaries shall, and the Company shall not authorize or permit its directors, officers, employees, investment bankers, attorneys, accountants and other advisors or representatives (such directors, officers, employees, investment bankers, attorneys, accountants, other advisors and representatives, collectively, “Representatives”) to, directly or indirectly:

(i) solicit, initiate, knowingly encourage or knowingly facilitate any inquiries or the making of any proposal or offer that constitutes, or would reasonably be expected to lead to, any Acquisition Proposal; or

(ii) enter into, continue or otherwise participate in any discussions or negotiations with, or furnish any non-public information to, any Person (other than the Parent or its Representatives) relating to any Acquisition Proposal.

Notwithstanding the foregoing or anything to the contrary set forth in this Agreement, in response to a bona fide written Acquisition Proposal that did not result from a material breach of this Section 6.1, and subject to compliance with Section 6.1(c), prior to the Acceptance Time, the Company may (A) furnish non-public information with respect to the Company and its Subsidiaries to any Person (and the Representatives of such Person) making an Acquisition Proposal that the Company Board determines in good faith (after consultation with outside counsel and its financial advisors) is, or is reasonably likely to lead to, a Superior Proposal (such Person, a “Qualified Person”) pursuant to a confidentiality agreement not less restrictive in any material respect with respect to the Qualified Person than the Confidentiality Agreement, and (B) engage in discussions or negotiations (including solicitation of revised Acquisition Proposals) with any Qualified Person (and the Representatives of such Qualified Person) regarding any such Acquisition Proposal.

The Company (x) shall not, and shall cause its Subsidiaries not to, terminate, waive, amend or modify any provision of, or grant permission or request under, any standstill or confidentiality agreement to which it or any of its Subsidiaries is or becomes a party, and (y) shall, and shall cause its Subsidiaries to, use commercially reasonable efforts to enforce the provisions of any such agreement; provided, however, that the Company and its Subsidiaries may terminate, waive, amend or modify any provision of, or grant any permission or request under, any standstill agreement relating to the submission of any unsolicited Acquisition Proposal if the Company Board determines in good faith, after consultation with outside counsel, that failure to do so would be inconsistent with the fiduciary duties of the Company Board to the stockholders of the Company under applicable Law. The Company will promptly provide to the Parent any non-public information concerning the Company or its Subsidiaries provided or made available pursuant to this Section 6.1(a) which was not previously provided or made available to the Parent.

- 48 -

(b) No Change in Recommendation or Alternative Acquisition Agreement. Prior to the Specified Time:

(i) the Company Board shall not, except as set forth in this Section 6.1, withhold, withdraw, qualify or modify, or propose publicly to withhold, withdraw, qualify or modify, in each case in a manner adverse to the Parent, the approval or recommendation by the Company Board with respect to the Offer or the Company Voting Proposal (a “Company Board Recommendation Change”);

(ii) the Company shall not enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or similar agreement (an “Alternative Acquisition Agreement”) providing for the consummation of a transaction contemplated by any Acquisition Proposal (other than a confidentiality agreement referred to in Section 6.1(a) entered into in the circumstances referred to in Section 6.1(a)); and

(iii) the Company Board shall not, except as set forth in this Section 6.1, adopt, approve or recommend any Acquisition Proposal.

Notwithstanding the foregoing or anything to the contrary set forth in this Agreement (including the provisions of this Section 6.1), prior to the Acceptance Time, if (A) the Company receives a written, bona fide Acquisition Proposal from a third party, (B) such Acquisition Proposal did not result from a material breach by the Company of this Section 6.1, and (C) the Company Board concludes in good faith, after consultation with outside counsel and its financial advisors, that such Acquisition Proposal constitutes a Superior Proposal after giving effect to all of the adjustments to the terms of this Agreement which may be offered by Parent pursuant to a written, binding and irrevocable offer to alter the terms or conditions of this Agreement, the Company Board may, if it determines in good faith, after consultation with outside counsel, that the failure to take action would be inconsistent with its fiduciary duties to the stockholders of the Company under applicable Law, (x) effect a Company Board Recommendation Change and/or (y) terminate this Agreement to enter into an Alternative Acquisition Agreement with respect to such Superior Proposal; provided, however, that the Company shall not terminate this Agreement pursuant to the foregoing clause (y), and any purported termination pursuant to the foregoing clause (y) shall be void and of no force or effect, unless in advance of or substantially concurrently with such termination the Company pays the fee required by and pursuant to the terms of Section 8.3 and promptly following such termination enters into a binding definitive contract for such Superior Proposal; and provided, further, that the Company Board may not effect a Company Board Recommendation Change pursuant to the foregoing clause (x) or terminate this Agreement pursuant to the foregoing clause (y) unless (1) such Acquisition Proposal shall not have resulted from a material breach by the Company of this Section 6.1, (2) the Company shall have provided prior written notice to the Parent, at least three Business Days in advance (the “Notice Period”), of its intention to take such action with respect to such Superior Proposal, which notice shall specify the material terms and conditions of any such Superior Proposal (including the identity of the party making such Superior Proposal), and shall have contemporaneously provided a copy of the proposed Alternative Acquisition Agreement

- 49 -

with respect to such Superior Proposal, (3) prior to effecting such Company Board Recommendation Change or terminating this Agreement to enter into a definitive Alternative Acquisition Agreement with respect to such Superior Proposal, the Company shall, if requested by the Parent, make its Representatives available during the Notice Period to discuss with the Parent’s Representatives any modifications to the terms and conditions of this Agreement that the Parent desires to propose such that such Acquisition Proposal ceases to constitute a Superior Proposal, and (4) following any discussions described in the immediately preceding clause (3), the Company Board shall have determined in good faith that such Acquisition Proposal continues to constitute a Superior Proposal. In the event of any material revisions to the terms of the Superior Proposal after the start of the Notice Period, the Company shall be required to deliver a new written notice to the Parent and to comply with the requirements of this Section with respect to such new written notice, and the Notice Period shall be deemed to have re-commenced on the date of such new notice. Notwithstanding the foregoing, if fewer than three Business Days remain before the then scheduled expiration date of the Offer, the Notice Period with respect to the Company Board effecting a Company Board Recommendation Change pursuant to the foregoing clause (x) shall equal 24 hours, provided, however, that, in such a circumstance, the Notice Period with respect to the Company terminating this Agreement pursuant to the foregoing clause (y) shall remain three Business Days. Any Company Board Recommendation Change shall not change the approval of the Company Board for purposes of causing any state takeover statute or other Law to be inapplicable to the transactions contemplated by this Agreement, including each of the Offer and the Merger, or to the Tender and Voting Agreements.

Notwithstanding the foregoing, the Company Board may make a Company Board Recommendation Change in the absence of a Superior Proposal if the Company Board has concluded in good faith, after consultation with its outside counsel, that failure to take such action is inconsistent with its fiduciary duties to the stockholders of the Company under applicable Law, provided, however, that the Company Board shall not make a Company Board Recommendation Change unless the Company has provided to the Parent at least three Business Days’ prior written notice (or such shorter period as remains prior to the scheduled expiration date of the Offer) advising the Parent that the Company Board intends to take such action and specifying the reasons therefor in reasonable detail and during such three Business Day (or shorter) period, if requested by the Parent, the Company shall have engaged in good faith negotiations and made its Representatives available to discuss with the Parent’s Representatives any amendment to this Agreement that the Parent desires to propose to obviate the need or reason for the Company Board Recommendation Change.

(c) Notices to the Parent. From and after the date hereof and prior to the Acceptance Time, the Company shall within one Business Day notify the Parent in the event that the Company or any of its Subsidiaries or Representatives receives (i) any Acquisition Proposal, (ii) any request for non-public information relating to the Company or any of its Subsidiaries other than requests for information in the Ordinary Course of Business and, in the good faith judgment of the Company Board, unrelated to an Acquisition Proposal, or (iii) any inquiry or request for discussions or negotiations regarding any Acquisition Proposal. The Company shall provide Parent within such one Business Day period with the identity of such Person and a copy of such Acquisition Proposal (or, where such Acquisition Proposal is not in writing, a description of the material terms and conditions of such Acquisition Proposal). The Company shall keep the

- 50 -

Parent reasonably informed in writing (and in any event no later than one Business Day) after the occurrence of any material changes, developments, discussions or negotiations relating to such Acquisition Proposal, including furnishing copies of any material written inquiries, correspondence and draft documentation, and written summaries of any material oral inquiries or discussions. Without limiting the foregoing, the Company shall within one Business Day notify the Parent in writing if it determines to begin providing non-public information or to engage in discussions or negotiations concerning an Acquisition Proposal. The Company shall not, and shall cause its Subsidiaries not to, enter into any agreement with any Person subsequent to the date of this Agreement that would restrict the Company’s ability to provide such information to the Parent, and, if the Company is a party to any agreement that would prohibit the Company from providing such information to the Parent, prior to providing non-public information to, or engaging in discussions or negotiations with, the counterparty to such agreement, the Company will obtain approval from the counterparty to such agreement to allow the Company to provide such information to the Parent.

(d) Certain Permitted Disclosure. Notwithstanding anything to the contrary in this Agreement, nothing contained in this Agreement shall prohibit the Company, any of its Subsidiaries or the Company Board from (i) taking and disclosing to its stockholders a position with respect to a tender offer contemplated by Rule 14d-9 or Rule 14e-2 promulgated under the Exchange Act, or from issuing a “stop, look and listen” statement pending disclosure of its position thereunder, or (ii) making any disclosure to the Company’s stockholders if, in the good faith judgment of the Company Board, after consultation with outside counsel, failure to so disclose would be inconsistent with its obligations under applicable Law.

(e) Cessation of Ongoing Discussions. The Company shall, and shall cause its Representatives to, cease immediately all discussions and negotiations that commenced prior to the date of this Agreement regarding any proposal that constitutes, or could reasonably be expected to lead to, an Acquisition Proposal and shall promptly demand to be returned (or destroyed, to the extent permitted by the terms of the applicable confidentiality agreement) all confidential information provided by or on behalf of the Company or any of its Subsidiaries to any such Person.

(d) The Parent and the Purchaser shall cause the Merger to be effected promptly following the acceptance for payment of any shares of Company Common Stock pursuant to the Offer, including by taking all actions necessary to cause the Merger to be consummated pursuant to Section 253 of the DGCL if permitted by the DGCL.

6.3 Nasdaq Listing; Post-Closing SEC Reports. The Company shall use its commercially reasonable efforts to continue the listing of the Company Common Stock on The Nasdaq Stock Market during the term of this Agreement. Prior to the Effective Time, the Company shall cooperate with the Parent and use commercially reasonable efforts to take, or cause to be taken, all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under applicable Laws and rules and policies of The Nasdaq Stock Market to enable the delisting by the Surviving Corporation of the shares of Company Common Stock from The Nasdaq Stock Market and the deregistration of the shares of Company Common Stock under the Exchange Act promptly after the Effective Time. The Parent will use commercially reasonable efforts to cause the Surviving Corporation to file with the SEC (a) a Form 25 on the Closing Date and (b) a Form 15 on the first Business Day that is at least ten (10) days after the date the Form 25 is filed (such period between the Form 25 filing date and the Form 15 filing date, the “Delisting Period”). If the Surviving Corporation is reasonably likely to be required to file any reports pursuant to the Exchange Act during the Delisting Period, the Company will deliver to the Parent at least five (5) Business Days prior to the Closing a substantially final draft of any such reports reasonably likely to be required to be filed during the Delisting Period (“Post-Closing SEC Reports”). The Post-Closing SEC Reports provided by the Company pursuant to this Section 6.3 will (i) 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 made therein, in the light of the circumstances under which they were made, not misleading and (ii) comply in all material respects with the provisions of applicable Laws.

6.4 Confidentiality; Access to Information.

(a) The parties hereto acknowledge that the Parent and the Company have previously executed a confidentiality agreement, dated as of August 3, 2009 (the “Confidentiality Agreement”), which Confidentiality Agreement shall continue in full force and effect in accordance with its terms, except as expressly modified herein.

(b) During the Pre-Closing Period, the Company shall (and shall cause each of its Subsidiaries to) afford to the Parent’s officers, employees, accountants, counsel and other representatives, reasonable access, upon reasonable notice, during normal business hours and in

a manner that does not disrupt or interfere with business operations, to all of its properties, books, contracts, personnel and records as the Parent shall reasonably request, and, during such period, the Company shall (and shall cause each of its Subsidiaries to) furnish promptly to the Parent (a) a copy of each report, schedule, registration statement and other document filed or received by it during such period pursuant to the requirements of federal or state securities Laws and (b) all other information concerning its business, properties, assets and personnel as the Parent may reasonably request; provided, however, that the Company shall not be required to permit any inspection or other access, or to disclose any information, (i) in connection with an Acquisition Proposal or Company Board Recommendation Change (except as expressly set forth in Section 6.1) or (ii) that in the reasonable judgment of the Company would: (A) result in the disclosure of any trade secrets of any third party, (B) violate any obligation of the Company with respect to confidentiality entered into prior to the date of this Agreement, (C) violate or result in the loss or material impairment of any information subject to the attorney-client privilege or the attorney work product doctrine or (D) violate any legal requirement. No investigation by the Parent shall diminish or obviate any of the representations, warranties, covenants or agreements of the Company contained in this Agreement. The Parent will hold any such information which is non-public in confidence in accordance with the Confidentiality Agreement.

6.5 Legal Conditions to the Merger.

(a) Subject to the terms hereof, including Section 6.1 and Section 6.5(b), the Company and the Parent shall each use its reasonable best efforts to:

(ii) as promptly as practicable, obtain from any Governmental Entity or any other Person any consents, licenses, permits, waivers, approvals, authorizations, or orders required to be obtained or made by the Company or the Parent or any of their Subsidiaries in connection with the authorization, execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby; provided, however, that in no event shall the Company or any of its Subsidiaries be required to pay prior to the Acceptance Time any material fee, penalties or other consideration to any third party to obtain any consent or approval required for the consummation of the Offer or the Merger;

(iii) as promptly as practicable, make all necessary filings, notices, statements, registrations, submissions of information, applications or submissions of other documents, with respect to this Agreement, the Offer and the Merger required under (A) the Exchange Act, and any other applicable federal or state securities Laws, (B) the HSR Act, any other applicable Antitrust Laws and any related governmental request thereunder and (C) any other applicable Law;

(iv) oppose any Law which has the effect of prohibiting consummation of the Offer or making the Merger illegal or otherwise prohibiting consummation of the Offer,

the Merger or the other transactions contemplated by this Agreement, or have any such Law vacated or made inapplicable to the Offer, the Merger and the other transactions contemplated by this Agreement; and

(v) execute or deliver any additional instruments necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, this Agreement.

The Company and the Parent shall cooperate with each other in connection with the making of all such filings, including providing copies of all such documents to the non-filing Person and its advisors prior to filing and, if requested, accepting reasonable additions, deletions or changes suggested in connection therewith. The Company and the Parent shall use their respective reasonable best efforts to furnish to each other all information required for any application or other filing to be made pursuant to applicable Law (including all information required to be included in the Proxy Statement (if any) to be sent to the stockholders of the Company in connection with the Company Stockholder Approval) in connection with the transactions contemplated by this Agreement. Notwithstanding anything to the contrary contained herein or in Section 6.5(b), it is understood and agreed that, in the case of filings pursuant to the HSR Act and other applicable Antitrust Laws, the Parent may redact certain sensitive financial, valuation and business information prior to providing such documents to the Company.

(b) Subject to the terms hereof, the Parent and the Company agree, and shall cause each of their respective Subsidiaries, to cooperate and to use their respective reasonable best efforts to obtain any applicable government clearances or approvals under the HSR Act, the Sherman Act, the Clayton Act, the Federal Trade Commission Act and any other applicable Law designed to prohibit, restrict or regulate actions for the purpose or effect of monopolization or restraint of trade (collectively “Antitrust Laws”), to respond to any government requests for information under any Antitrust Law, and to contest and resist any action, including any legislative, administrative or judicial action, and to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order (whether temporary, preliminary or permanent) (an “Antitrust Order”) that restricts, prevents or prohibits the consummation of the Merger or any other transaction contemplated by this Agreement under any Antitrust Law. Without limiting the generality of the foregoing, each of the Parent and the Company shall file, no later than the tenth (10th) Business Day after the date of this Agreement, with the Federal Trade Commission and the Antitrust Division of the U.S. Department of Justice a Notification and Report Form relating to this Agreement and the transactions contemplated hereby (including the Offer and the Merger) as required by the HSR Act, and, as soon as may be reasonably practicable following the date of this Agreement, any applicable comparable pre-merger notification filings, forms and submissions with any foreign Governmental Entity. The parties hereto will consult and cooperate with one another, and consider in good faith the views of one another, in connection with, and provide to the other parties in advance, any material analyses, appearances, presentations, memoranda, briefs, arguments, opinions and proposals made or submitted by or on behalf of any party hereto in connection with proceedings under or relating to any Antitrust Law.

(c) Nothing in this Agreement shall require the Parent, the Surviving Corporation or any other Subsidiary of the Parent to sell, hold separate, license or otherwise

- 55 -

dispose of any assets or conduct their business in a specified manner, or agree or proffer to sell, hold separate, license or otherwise dispose of any assets or conduct their business in a specified manner, or permit or agree to the sale, holding separate, licensing or other disposition of, any assets of the Parent, the Surviving Corporation or any other Subsidiary of the Parent or the Company, whether as a condition to obtaining any approval from, or to avoid potential litigation or administrative action by, a Governmental Entity or any other person or for any other reason.

(d) Each of the Company and the Parent shall give (or shall cause their respective Subsidiaries to give) any notices to third parties, and use, and cause their respective Subsidiaries to use, their respective commercially reasonable efforts to obtain any consents required in connection with the Offer and the Merger that are (i) necessary to consummate the transactions contemplated hereby, (ii) disclosed or required to be disclosed in the Company Disclosure Schedule or (iii) required to prevent the occurrence of an event that is reasonably likely to have a Company Material Adverse Effect prior to or after the Effective Time.

(e) The Company shall take, or cause to be taken, the actions necessary so that those individuals serving on the boards of directors or comparable body of each Subsidiary of the Company will resign and be replaced by individuals specified by the Parent effective as of the Effective Time.

6.6 Public Disclosure. Except as may be required by Law or stock market regulations, (a) the press release announcing the execution of this Agreement shall be issued only in such form as shall be mutually agreed upon by the Company and the Parent and (b) the Parent and the Company shall obtain the consent of the other party before issuing any other press release or otherwise making any public statement with respect to the Offer, the Merger or this Agreement, which consent shall not be unreasonably withheld or delayed; provided, however, that these restrictions shall not apply to any Company communications regarding an Acquisition Proposal or Company Board Recommendation Change. Notwithstanding the foregoing, without prior consent of the other party, each party may communicate information that is not confidential to either party with financial analysts, investors and media representatives in a manner consistent with its past practice in compliance with applicable Law and may disseminate material substantially similar to material included in a press release or other document previously approved for external distribution by the other parties. Each party agrees to promptly make available to the other parties copies of any written communications made without prior consultation with the other parties.

6.7 Indemnification.

(a) From and after the Effective Time through the six-year anniversary of the date on which the Effective Time occurs, the Surviving Corporation shall indemnify and hold harmless each Person who is now, or has been at any time prior to the date hereof, or who becomes prior to the Effective Time, a director or officer of the Company or any of its Subsidiaries (the “Indemnified Parties”), against all claims, losses, liabilities, damages, judgments, fines and reasonable fees, costs and expenses, including attorneys’ fees and disbursements, incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to the fact that the Indemnified Party is or was an officer, director, employee or agent of the Company or any of

- 56 -

its Subsidiaries or, while a director or officer of the Company or one of its Subsidiaries, is or was serving at the request of the Company or one of its Subsidiaries as a director, officer, employee or agent of another Person, whether asserted or claimed prior to, at or after the Effective Time, to the fullest extent that the Company is obligated to indemnify and hold harmless such individuals on the date of this Agreement pursuant to the Company’s certificate of incorporation and bylaws as in effect on the date of this Agreement and the indemnification agreements approved by the Company Board on August 5, 2009 and in effect on the date hereof, and Parent guarantees any such obligations of the Surviving Corporation. Each Indemnified Party will be entitled to advancement of expenses (including attorneys’ fees) incurred in the defense of any such claim, action, suit, proceeding or investigation from the Surviving Corporation to the fullest extent that the Company is obligated to advance expenses to such individuals on the date of this Agreement pursuant to the Company’s certificate of incorporation and bylaws as in effect on the date of this Agreement and the indemnification agreements approved by the Company Board on August 5, 2009 and in effect on the date hereof; provided that any Indemnified Party to whom expenses are advanced provides an undertaking, to the extent required by the DGCL, to repay such advances if it is determined by a final determination of a court of competent jurisdiction (which determination is not subject to appeal) that such Indemnified Party is not entitled to indemnification under applicable Law.

(b) From the Effective Time through the six-year anniversary of the date on which the Effective Time occurs, the certificate of incorporation and bylaws of the Surviving Corporation shall contain, and the Parent shall cause the certificate of incorporation and bylaws of the Surviving Corporation to so contain, provisions no less favorable with respect to indemnification, advancement of expenses and exculpation of present and former directors and officers of the Company and its Subsidiaries than are set forth in the certificate of incorporation and bylaws of the Company as in effect on the date of this Agreement.

(c) Subject to the next sentence, the Surviving Corporation shall either (i) maintain, and the Parent shall cause the Surviving Corporation to maintain, at no expense to the beneficiaries, in effect for six (6) years from the Effective Time the current policies of the directors’ and officers’ liability insurance maintained by the Company (the “Current D&O Insurance”) with respect to matters existing or occurring at or prior to the Effective Time (including the transactions contemplated by this Agreement), so long as the annual premium therefor would not be in excess of 250% of the last annual premium paid prior to the Effective Time (such 250%, the “Maximum Premium”), or (ii) purchase a six (6) year extended reporting period endorsement with respect to the Current D&O Insurance (a “Reporting Tail Endorsement”) and maintain such endorsement in full force and effect for its full term, provided, however, that prior to the Surviving Corporation taking any actions in clauses (i) or (ii) above, the Parent shall be provided the opportunity to purchase, in lieu thereof, a substitute policy with the same coverage limits and substantially similar terms as in the Reporting Tail Endorsement proposed to be purchased by the Surviving Corporation. If the Company’s or the Surviving Corporation’s existing insurance expires, is terminated or canceled during such six-year period or exceeds the Maximum Premium, the Surviving Corporation shall obtain, and the Parent shall cause the Surviving Corporation to obtain, as much directors’ and officers’ liability insurance as can be obtained for the remainder of such period for an annualized premium not in excess of the Maximum Premium, on terms and conditions no less advantageous to the Indemnified Parties than the Company’s existing directors’ and officers’ liability insurance.

- 57 -

(d) In the event the Parent or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Parent or the Surviving Corporation, as the case may be, shall expressly assume and succeed to the obligations set forth in this Section 6.7.

(e) If any Indemnified Party makes any claim for indemnification or advancement of expenses under this Section 6.7 that is denied by the Parent and/or the Company or the Surviving Corporation, and a court of competent jurisdiction determines that the Indemnified Party is entitled to such indemnification or advancement of expenses, then the Parent, the Company or the Surviving Corporation shall pay the Indemnified Party’s costs and expenses, including reasonable legal fees and expenses, incurred by the Indemnified Party in connection with pursuing his or her claims to the fullest extent permitted by Law.

(f) The provisions of this Section 6.7 are intended to be in addition to the rights otherwise available to the current officers and directors of the Company by Law, charter, statute, bylaw or agreement, and shall operate for the benefit of, and shall be enforceable by, each of the Indemnified Parties, their heirs and their representatives.

6.8 Notification of Certain Matters. Prior to the Acceptance Time, the Parent shall give prompt notice to the Company, and the Company shall give prompt notice to the Parent, of (a) the occurrence, or failure to occur, of any event, of which such party has Knowledge that is reasonably expected to cause any representation or warranty contained in this Agreement to become untrue or inaccurate such that it is reasonably expected to have a Company Material Adverse Effect or Parent Material Adverse Effect, as the case may be, until the Acceptance Time or (b) any material failure of the Parent and the Purchaser or the Company, as the case may be, or of any officer, director, employee or agent thereof, of which such party has Knowledge to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it under this Agreement; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties, the conditions to the obligations of the parties under this Agreement or the remedies available to the party receiving such notification. Without limiting the foregoing, the Company shall, within twenty-four (24) hours after it has actual Knowledge of any of the following, notify the Parent of (i) any notice or other communication from any Person alleging that the consent of such Person is or may be required pursuant to any contract or agreement listed in the Company Disclosure Schedule in connection with the transactions contemplated by this Agreement or is otherwise required to consummate the Offer or the Merger, (ii) any notice or other communication from any Governmental Entity in connection with the transactions contemplated by this Agreement, and (iii) any actions, suits, claims, investigations or proceedings instituted or threatened against the Company or any of its directors, officers or Affiliates, including by any stockholder of the Company, before any court or Governmental Entity, relating to or involving or otherwise affecting the Company or any of its Subsidiaries which, if pending on the date of this Agreement, would have been required to have been disclosed pursuant to this Agreement or relating to this Agreement or the transactions contemplated hereby, or seeking damages or discovery in connection with such transactions. The Company shall consult with the Parent regarding the

- 58 -

defense or settlement of any such actions, suits, claims, investigations or proceedings and shall consider the Parent’s views with respect to such actions, suits, claims, investigations or proceedings.

6.9 Employee Benefits Matters.

(a) From and after the Effective Time, the Parent shall, and shall cause the Surviving Corporation to provide, for a period of one year following the Effective Time, to each employee of the Company and its Subsidiaries (“Company Employees”) a total compensation package (including base salary, annual target bonus opportunity, and other employee benefits, but excluding the value of equity or other long-term incentive awards) that is substantially comparable, in the aggregate, to the total compensation package (including base salary, annual target bonus opportunity and other employee benefits, but excluding the value of equity or other long-term incentive awards) provided to such employees immediately before the Effective Time.

(b) For all purposes (including purposes of vesting, eligibility to participate and level of benefits) under the employee benefit plans of the Parent and its Subsidiaries providing benefits to any Company Employees after the Effective Time (the “New Plans”), each Company Employee shall, subject to applicable Law and applicable tax qualification requirements, be credited with his or her years of service with the Company and its Subsidiaries and their respective predecessors before the Effective Time, to the same extent as such Company Employee was entitled, before the Effective Time, to credit for such service under any similar Company Employee benefit plan in which such Company Employee participated or was eligible to participate immediately prior to the Effective Time; provided that the foregoing shall not apply to the extent that its application would result in a duplication of benefits. In addition, and without limiting the generality of the foregoing, (i) each Company Employee shall be immediately eligible to participate, without any waiting time, in any and all New Plans to the extent coverage under such New Plan is comparable to the Company Employee Plan in which such Company Employee participated immediately before the consummation of the Merger (such plans, collectively, the “Old Plans”), and (ii)(A) for purposes of each New Plan providing medical, dental, pharmaceutical or vision benefits to any Company Employee, the Parent shall cause all pre-existing condition exclusions and actively-at-work requirements of such New Plan to be waived for such Company Employee and his or her covered dependents, unless such conditions would not have been waived under the Old Plan of the Company or its Subsidiaries in which such Company Employee participated immediately prior to the Effective Time and (B) the Parent shall cause any eligible expenses incurred by such employee and his or her covered dependents during the portion of the plan year of the Old Plan ending on the date such employee’s participation in the corresponding New Plan begins to be taken into account under such New Plan for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such employee and his or her covered dependents for the applicable plan year as if such amounts had been paid in accordance with such New Plan.

(c) From and after the Effective Time, the Parent shall, and shall cause the Surviving Corporation to, honor all of the obligations of the Company and its Subsidiaries under the severance and change in control plans and policies set forth in Section 3.14(i) of the Company Disclosure Schedule, and any payments under those plans and policies will be in lieu of any other severance under plans or policies of Parent, Purchaser or the Surviving Corporation.

- 59 -

(d) Except with the prior written consent of the Parent, during the period from the date of this Agreement to the Effective Time, the Company shall not (i) make any discretionary contribution to the Company’s 401(k) plan, other than employer matching contributions at the rate in effect immediately prior to the date of this Agreement, or (ii) make any required contribution to the Company’s 401(k) plan in shares. If requested by the Parent in writing, the Company shall terminate the Company’s 401(k) plan immediately prior to the Effective Time.

(e) Parent and its Subsidiaries shall take and assume all responsibility, steps, liability and costs necessary to either transfer, or apply for, petitions or applications with the U.S. Department of Homeland Security or the U.S. Department of Labor for employees who are non-immigrant temporary workers or in the process of applying for permanent residence. This includes abiding by the terms and conditions of these petitions and applications, filing any new documents, necessary amendments or withdrawals, and abiding by applicable Law.

(d) by the Parent or the Company if the Offer (as it may have been extended pursuant to Section 1.1(b)) expires as a result of the non-satisfaction of the Offer Conditions, without the Purchaser having accepted for payment any shares of Company Common Stock validly tendered (and not validly withdrawn) pursuant to the Offer; provided, however, that a party hereto shall not be permitted to terminate this Agreement pursuant to this Section 8.1(d) if the non-satisfaction of the Offer Conditions is attributable to the failure of such party (or any Affiliate of such party) to fulfill any of its obligations under this Agreement;

(e) by the Parent, prior to the purchase of any shares of Company Common Stock pursuant to the Offer, if: (i) the Company Board shall have failed to recommend the tender of shares of Company Common Stock pursuant to the Offer in the Schedule 14D-9 or approval of the Company Voting Proposal or shall have effected a Company Board Recommendation Change; (ii) the Company Board shall have approved, endorsed or recommended to the stockholders of the Company an Acquisition Proposal (other than the Offer and the Merger) or entered into or publicly announced its intention to enter into any agreement with respect to any Acquisition Proposal (other than the Offer and the Merger); (iii) the Company Board shall have failed to reaffirm its approval and recommendation in favor of the Offer, the Merger, this Agreement or the Company Voting Proposal within four Business Days of the Parent’s request, which request may only be made after a public announcement of an Acquisition Proposal by a Person other than the Parent or the Purchaser or any of their respective Affiliates (provided that the Parent is only allowed to make two such reaffirmation requests prior to the Acceptance Time); (iv) a tender offer or exchange offer for outstanding shares of Company Common Stock shall have been commenced (other than by the Parent or an Affiliate of the Parent) and the Company Board shall have recommended that the stockholders of the Company tender their shares in such tender or exchange offer or, within 10 Business Days after the commencement of such tender or exchange offer, the Company Board shall have taken a neutral position, or failed to recommend against, acceptance of such offer; or (v) after the Company’s receipt of any Acquisition Proposal, the Company shall have violated or breached in any material respect its obligations under Section 6.1 with respect to such Acquisition Proposal (each of clauses (i) through (iv), a “Trigger Event”);

(f) by the Company, at any time prior to the Acceptance Time, pursuant to the terms of Section 6.1(b), in order to enter into an Alternative Acquisition Agreement with respect to a Superior Proposal;

(g) by the Parent, at any time prior to the Acceptance Time , if there has been a breach by the Company of, failure to perform or inaccuracy in, any representation, warranty, covenant or agreement on the part of the Company set forth in this Agreement, which breach,

- 62 -

failure to perform or inaccuracy (i) has resulted in the conditions set forth in clauses (c)(iii) or (c)(iv) of Annex I not being satisfied, and (ii) shall not have been cured within 20 Business Days following receipt by the Company of written notice of such breach, failure to perform or inaccuracy from the Parent;

(h) by the Company, at any time prior to the Acceptance Time, if there has been a breach by the Parent or the Purchaser of, failure to perform or inaccuracy in, any representation, warranty, covenant or agreement on the part of the Parent or the Purchaser set forth in this Agreement, which breach, failure to perform or inaccuracy (i) has resulted in any of the conditions set forth in Article 7 not being satisfied and (ii) shall not have been cured within 20 Business Days following receipt by the Parent of written notice of such breach, failure to perform or inaccuracy from the Company; or

(i) by the Company (A) if, for any reason, the Purchaser shall have failed to commence the Offer by the date that is 10 Business Days after the date of this Agreement, provided, however, that the Company may not terminate this Agreement pursuant to this Section 8.1(i) if such failure to commence the Offer has resulted from the breach of this Agreement by the Company or if the Company has not provided the Purchaser with a Schedule 14D-9 the Company is prepared to file, without further revisions (subject only to review, and revisions required following such review, of the Purchaser’s Schedule TO), upon commencement of the Offer.

8.2 Effect of Termination. In the event of termination of this Agreement as provided in Section 8.1 and the payment, if due pursuant to Section 8.3(b)(ii), of the Termination Fee, this Agreement shall immediately become void and there shall be no liability or obligation on the part of the Parent, the Company, the Purchaser or their respective officers, directors, stockholders or Affiliates; provided that, subject to Section 8.3(d), (a) any such termination shall not relieve any party hereto from liability for any fraud or intentional breach of this Agreement (it being understood that the failure of the Parent or the Purchaser to accept for payment and pay for the shares of Company Common Stock validly tendered and not validly withdrawn pursuant to the Offer promptly following the Expiration Date in the event that all Offer Conditions have been satisfied or, to the extent permitted, waived, as of the Expiration Date shall be deemed an intentional breach by the Parent and the Purchaser pursuant to this Agreement), and (b) the provisions of Section 6.4 (Confidentiality), this Section 8.2 (Effect of Termination), Section 8.3 (Fees and Expenses) and Article IX (Miscellaneous) of this Agreement and the Confidentiality Agreement shall remain in full force and effect and survive any termination of this Agreement.

8.3 Fees and Expenses.

(a) Except as set forth in this Section 8.3, all fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such fees and expenses, whether or not the Offer or the Merger is consummated.

(b) The Company shall pay the Parent a termination fee of $8,000,000 (the “Termination Fee”) in the event that this Agreement is terminated:

(i) by the Parent pursuant to Section 8.1(e);

- 63 -

(ii) by the Company pursuant to Section 8.1(f); or

(iii) by the Parent pursuant to Section 8.1(d) or (g) (but only, in the case of Section 8.1(g), as a result of an intentional or knowing material breach by the Company of a covenant or agreement of the Company set forth in this Agreement after the date hereof), so long as (A) before the date of such termination, an Acquisition Proposal shall have been publicly announced and not withdrawn and (B) within 12 months after the date of termination, the Company shall have consummated an Acquisition Proposal or the Company shall have entered into a definitive agreement for a transaction contemplated by an Acquisition Proposal (which Acquisition Proposal is ultimately consummated);

provided, however, that, for purposes of this Section 8.3(b), all references to “20%” in the definition of “Acquisition Proposal” shall be deemed to be references to “50%”. Any fee due under Section 8.3(b)(i) shall be paid to the Parent by wire transfer of same-day funds within two Business Days after the date of termination of this Agreement. Any fee due under Section 8.3(b)(ii) shall be paid to the Parent by wire transfer of same-day funds on the date of termination of this Agreement. Any fee due under Section 8.3(b)(iii) shall be paid to the Parent by wire transfer of same-day funds on the date on which the transaction referenced in clause (B) of Section 8.3(b)(iii) is consummated. If the Company fails to promptly make any payment required under this Section 8.3(b) and the Parent commences a suit to collect such payment, the Company shall indemnify the Parent for its fees and expenses (including attorneys fees and expenses) incurred in connection with such suit and shall pay interest on the amount of the payment at the prime rate of Bank of America (or its successors or assigns) in effect on the date the payment was payable pursuant to this Section 8.3(b).

(c) The parties hereto acknowledge and agree that in no event shall the Company be required to pay the Termination Fee on more than one occasion, whether or not the Termination Fee may be payable under more than one provision of this Agreement at the same or at different times and the occurrence of different events.

(d) The parties hereto acknowledge that the agreements contained in this Section 8.3 are an integral part of the transactions contemplated by this Agreement and that, without these agreements, the parties hereto would not enter into this Agreement.

8.4 Amendment. This Agreement may be amended by the written agreement of the parties hereto at any time before or after approval of the matters presented in connection with the Merger by the stockholders of any party hereto, but, after any such approval, no amendment shall be made which by Law requires further approval by such stockholders without such further approval. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

8.5 Extension; Waiver. At any time prior to the Effective Time, the parties hereto may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of the other parties hereto, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto and (c) waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set

- 64 -

forth in a written instrument signed on behalf of such party. Such extension or waiver shall not apply to any time for performance, inaccuracy in any representation or warranty, or noncompliance with any agreement or condition, as the case may be, other than that which is specified in the extension or waiver. The failure of any party hereto to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.

8.6 Procedure for Termination, Amendment, Extension or Waiver. A termination of this Agreement pursuant to Section 8.1, an amendment, modification or supplement of this Agreement pursuant to Section 8.4 or an extension or waiver of this Agreement pursuant to Section 8.5 shall, in order to be effective, require, in the case of the Purchaser or the Company, action by its Board of Directors or the duly authorized designee of its Board of Directors (which, in the case of the Company, shall include the approval contemplated by Section 1.3(c)).

9.3 Entire Agreement.

If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term.

This Agreement may be executed and delivered by facsimile or by an electronic scan delivered by electronic mail.

9.9 Governing Law.

9.10 Remedies.

(a) Except as otherwise provided herein, any and all remedies herein expressly conferred upon a Person will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such Person, and the exercise by a Person of any one remedy will not preclude the exercise of any other remedy.

(b) The parties hereto hereby agree that irreparable damage would occur in the event that any provision of this Agreement were not performed in accordance with its specific terms or were otherwise breached, and that money damages or other legal remedies would not be an adequate remedy for any such damages. Accordingly, the parties hereto acknowledge and agree that in the event of any breach or threatened breach by the Company, on the one hand, or the Parent and/or the Purchaser, on the other hand, of any of their respective covenants or obligations set forth in this Agreement, the Company, on the one hand, and the Parent and the Purchaser, on the other hand, shall be entitled to an injunction or injunctions to prevent or restrain breaches or threatened breaches of this Agreement, by the other (as applicable), and to specifically enforce the terms and provisions of this Agreement to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of the other under this Agreement. The Parent and the Purchaser hereby agree not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches or threatened breaches of this Agreement by the Parent and/or the Purchaser, and to specifically enforce the terms and provisions of this Agreement to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of the Parent and/or the Purchaser under this Agreement.

The inclusion of any information in the Company Disclosure Schedule shall not be deemed to be an admission or acknowledgment, in and of itself, that such information is required by the terms hereof to be disclosed, is material, has resulted in or would result in a Company Material Adverse Effect or is outside the Ordinary Course of Business.

9.13 Company’s Knowledge. For purposes of this Agreement, the term “Company’s Knowledge” means the actual knowledge of the individuals identified in Section 9.13(a) of the Company Disclosure Schedule after reasonable inquiry of the individuals set forth in Section 9.13(b) of the Company Disclosure Schedule.

The Parent shall not have any right of subrogation, reimbursement or indemnity whatsoever, nor any right of recourse to security for any of the agreements, covenants and obligations of the Purchaser or the Surviving Corporation under this Agreement.

9.15 Waiver of Jury Trial. EACH OF THE PARENT, COMPANY AND THE PURCHASER HEREBY IRREVOCABLY WAIVES THE RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED IN CONTRACT, TORT OR OTHERWISE) ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY RELATED DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALINGS, STATEMENT OR ACTION RELATED HERETO OR THERETO.

(b) immediately prior to the expiration of the Offer (as extended in accordance with the Agreement), any waiting period (and any extensions thereof) and any approvals or clearances applicable to the Offer or the consummation of the Merger under the HSR Act shall not have expired, or been terminated or obtained, as applicable; or

(c) at any time on or after the date of the Agreement and before the expiration of the Offer, any of the following shall occur and be continuing:

- 71 -

purchase some or all of the shares of Company Common Stock pursuant to the Offer or the Merger, (4) seeking to impose material limitations on the ability of the Purchaser or the Parent effectively to exercise full rights of ownership of the shares of Company Common Stock, including the right to vote the shares of Company Common Stock purchased by it on all matters properly presented to the Company’s stockholders, or (5) seeking to require divestiture by the Parent or any of its Subsidiaries of any shares of Company Common Stock;

(ii) there shall be any statute, rule, regulation, judgment, order or injunction enacted, entered, enforced, promulgated or deemed applicable, pursuant to an authoritative interpretation by or on behalf of a Governmental Entity, to the Offer or the Merger, or any other action shall be taken by any Governmental Entity, that would reasonably be expected to result, directly or indirectly, in any of the consequences referred to in clauses (1) through (5) of paragraph (i) above;

(iv) the Company shall have breached or failed to perform in any material respect its covenants and obligations required to be performed or complied with by it under the Agreement at or prior to the Acceptance Time;

- 72 -

may be waived by Parent or the Purchaser in whole or in part at any time and from time to time and in the sole discretion of Parent or the Purchaser, subject in each case to the terms of the Agreement. The failure by Parent or the Purchaser at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right and each such right shall be deemed an ongoing right which may be asserted at any time and from time to time prior to the Acceptance Time.
