Section 1.1 The Offer.

(a) Provided that this Agreement shall not have been terminated in accordance with Section 8.1, as promptly as practicable (and in any event within ten (10) business days) after the date hereof, Purchaser shall (and Parent shall cause Purchaser to) commence (within the meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (the “Exchange Act”)) the Offer to purchase for cash all Shares at the Offer Price, subject to:

(i) there being validly tendered in the Offer and not withdrawn prior to any then scheduled Expiration Date (as defined below) that number of Shares which, together with the Shares then beneficially owned by Parent or Purchaser (if any), represents at least a majority of:

(x) all Shares then outstanding, plus

(y) all Shares issuable upon the exercise, conversion or exchange of any Company Options, SARs, RSUs, Warrants, Equity Interests or other rights to acquire Shares then outstanding that are vested and exercisable, convertible or exchangeable as of any then scheduled Expiration Date or that would be vested and exercisable, convertible or exchangeable (including after giving effect to the acceleration of any vesting or exercisability, convertibility or exchangeability that may occur as a result of the Offer) at any time within sixty (60) days following the then scheduled Expiration Date assuming that the holder of such Company Options, SARs, RSUs, Warrants, Equity Interests or other rights satisfies the vesting or exercisability, convertibility or exchangeability conditions applicable thereto during such time period, less

(z) the number of Shares issuable upon the exercise of Company Options then outstanding held by ▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇ which are vested and exercisable as of the then scheduled Expiration Date or that would be vested and exercisable (including after giving effect to the acceleration of any vesting or exercisability that may occur as a result of the Offer) at any time within sixty (60) days following the then scheduled Expiration Date assuming that ▇▇. ▇▇▇▇▇▇▇▇ satisfies the vesting or exercisability conditions applicable thereto during such time period (the “Minimum Condition”); and

(ii) the satisfaction, or waiver by Parent or Purchaser, of the other conditions and requirements set forth in Annex I.

(b) The obligation of the Purchaser to accept for payment and pay for any Shares validly tendered and not withdrawn pursuant to the Offer shall be subject to the satisfaction of the Minimum Condition and the satisfaction, or waiver by Parent or Purchaser, of the other conditions and requirements set forth in Annex I. Subject to the prior satisfaction of the Minimum Condition and the satisfaction or waiver by Parent or Purchaser of the other conditions and requirements set forth in Annex I, Purchaser shall (and Parent shall cause Purchaser to) consummate the Offer in accordance with its terms and accept for payment and pay for all Shares validly tendered and not withdrawn pursuant to the Offer as promptly as practicable after Purchaser is legally permitted to do so under applicable law. The Offer Price payable in respect of each Share validly tendered and not withdrawn pursuant to the Offer shall be paid net to the Seller in cash subject to withholding as provide in Section 2.2(e).

(c) The Offer shall be made by means of an offer to purchase (the “Offer to Purchase”) that contains the terms set forth in this Agreement, the Minimum Condition and the other conditions and requirements set forth in Annex I. Parent and Purchaser expressly reserve the right to increase the Offer Price or to make any other changes in the terms and conditions of the offer; provided, however, that unless otherwise provided by this Agreement or as previously approved by the Company in writing, Purchaser shall not (i) decrease the Offer Price, (ii) change the form of consideration payable in the Offer, (iii) reduce the maximum number of Shares to be purchased in the Offer, (iv) impose conditions to the Offer that are different than or in addition to the conditions set forth in Annex I, (v) amend or waive the Minimum Condition, (vi) amend any of the conditions to the Offer set forth in Annex I, or (vii) extend the expiration of the Offer in a manner other than as required by this Agreement.

(d) Unless extended pursuant to and in accordance with the terms of this Agreement, the Offer shall expire at midnight (New York City time) on the date that is twenty (20) business days (for this purpose calculated in accordance with Rule 14d-1(g)(3) under the Exchange Act) following the commencement (within the meaning of Rule 14d-2 under the Exchange Act) of the Offer (the “Initial Expiration Date”) or, in the event the Initial Expiration Date has been extended pursuant to and in accordance with this Agreement, the date to which the Offer has been so extended (the Initial Expiration Date, or such later date to which the Initial Expiration Date has been extended pursuant to and in accordance with this Agreement, is referred to as the “Expiration Date”).

(e) The Offer shall be extended from time to time as follows:

(i) Offer Conditions Not Satisfied. If on or prior to any then scheduled Expiration Date, all of the conditions to the Offer (including the Minimum Condition and all other conditions and requirements set forth in Annex I) shall not have been satisfied,

or waived by Parent or Purchaser if permitted hereunder, Purchaser shall (and Parent shall cause Purchaser to) extend the Offer for successive periods of ten (10) business days each in order to permit the satisfaction of such conditions, or any lesser period ending on April 19, 2007 (the “Initial Outside Date”), or on December 19, 2007 in the event that the HSR Condition and/or the Governmental Approval Condition shall not have been satisfied, or waived by Parent and Purchaser if permitted hereunder, by the Initial Outside Date (the “Extended Outside Date”), if any such ten-day extension would otherwise end after the Initial Outside Date or the Extended Outside Date, as applicable.

(ii) Required by Applicable Law or Nasdaq. Purchaser shall extend the Offer for any period or periods required by applicable law, rule, regulation, interpretation or position of the SEC (or its staff) or Nasdaq.

(f) If necessary to obtain sufficient Shares (without regard to the exercise of the 90% Top-Up Option) to reach the Short Form Threshold, Purchaser may, in its sole discretion, provide for a “subsequent offering period” in accordance with Rule 14d-11 under the Exchange Act. In the event that more than eighty percent (80%) of the then outstanding Shares have been validly tendered and not withdrawn pursuant to the Offer following the Expiration Date, Purchaser shall (and Parent shall cause Purchaser to) provide for a “subsequent offering period” in accordance with Rule 14d-11 under the Exchange Act of at least ten (10) business days immediately following the Expiration Date unless Parent and Purchaser exercise the 90% Top-Up Option. Subject to the terms and conditions of this Agreement and the Offer, Purchaser shall (and Parent shall cause Purchaser to) accept for payment, and pay for, all Shares that are validly tendered and not withdrawn pursuant to the Offer during such “subsequent offering period” promptly after any such Shares are tendered during such “subsequent offering period.” The Offer Documents will provide for the possibility of a “subsequent offering period” in a manner consistent with the terms of this Section 1.1(f).

(g) Purchaser shall not terminate the Offer prior to any scheduled Expiration Date without the prior written consent of the Company except in the event that this Agreement is terminated pursuant to Section 8.1. In the event that this Agreement is terminated pursuant to Section 8.1, Purchaser shall (and Parent shall cause Purchaser to) promptly (and in any event within twenty four (24) hours of such termination), irrevocably and unconditionally terminate the Offer.

(h) As soon as practicable after the commencement of the Offer (within the meaning of Rule 14d-2 under the Exchange Act), Parent and Purchaser shall file with the Securities and Exchange Commission (the “SEC”), pursuant to Regulation M-A under the Exchange Act (“Regulation M-A”), a Tender Offer Statement on Schedule TO with respect to the Offer (together with all amendments, supplements and exhibits thereto, the “Schedule TO”). The Schedule TO shall include, as exhibits, the Offer to Purchase and a form of letter of transmittal and summary advertisement (collectively, together with any amendments and supplements thereto, the “Offer Documents”). Parent and Purchaser agree to take all steps necessary to cause the Offer Documents to be filed with

the SEC and disseminated to holders of Shares, in each case as and to the extent required by the Exchange Act. Parent and Purchaser, on the one hand, and the Company, on the other hand, agree to promptly correct any information provided by it for use in the Offer Documents if and to the extent that it shall have become false or misleading in any material respect or as otherwise required by applicable law. Parent and Purchaser further agree to take all steps necessary to cause the Offer Documents, as so corrected (if applicable), to be filed with the SEC and disseminated to holders of Shares, in each case as and to the extent required by the Exchange Act. The Company and its counsel shall be given a reasonable opportunity to review the Schedule TO and the Offer Documents before they are filed with the SEC, and Parent and Purchaser shall give due consideration to all the reasonable additions, deletions or changes suggested thereto by the Company and its counsel. In addition, Parent and Purchaser shall provide the Company and its counsel with copies of any written comments, and shall inform them of any oral comments, that Parent, Purchaser or their counsel may receive from time to time from the SEC or its staff with respect to the Schedule TO or the Offer Documents promptly after receipt of such comments, and any written or oral responses thereto. The Company and its counsel shall be given a reasonable opportunity to review any such written responses and Parent and Purchaser shall give due consideration to all reasonable additions, deletions or changes suggested thereto by the Company and its counsel. If the Offer is terminated or withdrawn by Purchaser, or this Agreement is terminated prior to the purchase of Shares in the Offer, Purchaser shall promptly return, and shall cause any depository, acting on behalf of Purchaser to return, all tendered Shares to the registered holders thereof.

(i) The Offer Price shall be adjusted appropriately to reflect the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Common Stock), cash dividend, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to Common Stock occurring on or after the date hereof and prior to the Effective Time.

Section 1.2 Company Actions.

(a) Contemporaneous with the filing of the Schedule TO, the Company shall, in a manner that complies with Rule 14d-9 under the Exchange Act, file with the SEC a Tender Offer Solicitation/ Recommendation Statement on Schedule 14D-9 with respect to the Offer (together with all amendments, supplements and exhibits thereto, the “Schedule 14D-9” that shall, subject to the provisions of Section 5.3(c), contain the Company Recommendation. The Company further agrees to take all steps necessary to cause the Schedule 14D-9 to be filed with the SEC and disseminated to holders of Shares, in each case as and to the extent required by the Exchange Act. The Company, on the one hand, and Parent and Purchaser, on the other hand, agree to promptly correct any information provided by it for use in the Schedule 14D-9 if and to the extent that it shall have become false or misleading in any material respect or as otherwise required by applicable law. The Company further agrees to take all steps necessary to cause the Schedule 14D-9, as so corrected (if applicable), to be filed with the SEC and disseminated to holders of Shares, in each case as and to the extent required by

the Exchange Act. Parent, Purchaser and their counsel shall be given a reasonable opportunity to review the Schedule 14D-9 before it is filed with the SEC and the Company shall give due consideration to all reasonable additions, deletions or changes suggested thereto by Parent, Purchaser and their counsel. In addition, the Company shall provide Parent, Purchaser and their counsel with copies of any written comments, and shall inform them of any oral comments, that the Company or its counsel may receive from time to time from the SEC or its staff with respect to the Schedule 14D-9 promptly after the Company’s receipt of such comments, and any written or oral responses thereto. Parent, Purchaser and their counsel shall be given a reasonable opportunity to review any such written responses and the Company shall give due consideration to all reasonable additions, deletions or changes suggested thereto by Parent, Purchaser and their counsel.

(b) In connection with the Offer, the Company shall promptly furnish or cause to be furnished to Purchaser mailing labels, security position listings and any available listing or computer files containing the names and addresses of the record holders of the Shares as of the most recent practicable date, and shall promptly furnish Purchaser with such information and assistance (including, but not limited to, lists of holders of the Shares, updated promptly from time to time upon Purchaser’s request, and their addresses, mailing labels and lists of security positions) as Purchaser or its agent may reasonably request for the purpose of communicating the Offer to the record and beneficial holders of the Shares. 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, Purchaser shall hold in confidence the information contained in any such labels, listings and files, shall use such information only in connection with the Offer and the Merger and, if this Agreement shall be terminated, shall promptly deliver to the Company all copies of such information.

Section 1.3 Directors.

(a) Promptly after Purchaser accepts for payment and pays for any Shares tendered and not withdrawn pursuant to the Offer (the “Appointment Time”), and at all times thereafter, Purchaser shall be entitled to elect or designate such number of directors, rounded up to the next whole number, on the Company Board of Directors as is equal to the product of the total number of directors on the Company Board of Directors (giving effect to the directors elected or designated by Purchaser pursuant to this sentence) multiplied by the percentage that the aggregate number of Shares beneficially owned by Parent, Purchaser and any of its affiliates bears to the total number of Shares then outstanding. The Company shall, upon Purchaser’s request at any time following the purchase of and payment for Shares pursuant to the Offer, take such actions, including but not limited to promptly filling vacancies or newly created directorships on the Company Board of Directors, promptly increasing the size of the Company Board of Directors (including by amending the Bylaws of the Company if necessary so as to increase the size of the Company Board of Directors) and/or promptly securing the resignations of such number of its incumbent directors as are necessary or desirable to enable Purchaser’s designees to be so elected or designated to the Company Board of Directors, and shall use its best efforts to cause Purchaser’s designees to be so elected or designated at such time. The Company shall, upon Purchaser’s request following the Appointment Time, also cause

Persons elected or designated by Purchaser to constitute the same percentage (rounded up to the next whole number) as is on the Company Board of Directors of (i) each committee of the Company Board of Directors, (ii) each board of directors (or similar body) of each Company Subsidiary and (iii) each committee (or similar body) of each such board, in each case to the extent permitted by applicable law and the Marketplace Rules of the Nasdaq Global Market (the “Nasdaq”). Promptly after the Appointment Time, the Company shall take all action necessary to elect to be treated as a “controlled company” as defined by Nasdaq Marketplace Rule 4350(c) and make all necessary filings and disclosures associated with such status. The Company’s obligations under this Section 1.3(a) shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder. The Company shall promptly upon execution of this Agreement take all actions required pursuant to Section 14(f) and Rule 14f-1 in order to fulfill its obligations under this Section 1.3(a), including mailing to stockholders (together with the Schedule 14D-9) the information required by Section 14(f) and Rule 14f-1 as is necessary to enable Purchaser’s designees to be elected or designated to the Company Board of Directors. Purchaser shall supply the Company with information with respect to Purchaser’s designees and Parent’s and Purchaser’s respective officers, directors and affiliates to the extent required by Section 14(f) and Rule 14f-1. The provisions of this Section 1.3(a) are in addition to and shall not limit any rights that any of Purchaser, Parent or any of their respective affiliates may have as a record holder or beneficial owner of Shares as a matter of applicable law with respect to the election of directors or otherwise.

(b) In the event that Purchaser’s designees are elected or designated to the Company Board of Directors pursuant to Section 1.3(a), then, until the Effective Time, the Company shall cause the Company Board of Directors to maintain three (3) directors who are members of the Company Board of Directors on the date hereof, each of whom shall be an “independent director” as defined by Rule 4200(a)(15) of the Nasdaq Marketplace Rules and eligible to serve on the Company’s audit committee under the Exchange Act and Nasdaq rules and, at least one of whom shall be an “audit committee financial expert” as defined in Item 401(h) of Regulation S-K and the instructions thereto (the “Continuing Directors”); provided, however, that if any Continuing Director is unable to serve due to death, disability or resignation, the Company shall take all necessary action (including creating a committee of the Company Board of Directors) so that the Continuing Director(s) shall be entitled to elect or designate another Person (or Persons) to fill such vacancy, and such Person (or Persons) shall be deemed to be a Continuing Director for purposes of this Agreement. If no Continuing Director then remains, the other directors shall designate three (3) Persons to fill such vacancies and such Persons shall be deemed Continuing Directors for all purposes of this Agreement. Notwithstanding anything in this Agreement to the contrary, if Purchaser’s designees constitute a majority of the Company Board of Directors after the Appointment Time and prior to the Effective Time, then the affirmative vote of a majority of the Continuing Directors shall (in addition to the approval rights of the Company Board of Directors or the stockholders of the Company as may be required by the Amended and Restated Certificate of Incorporation of the Company (as amended, the “Company Certificate”), the Amended and Restated Bylaws of the Company (as amended, the “Company Bylaws”, and together with the Company Certificate, the “Company Governing Documents”) or applicable law) be required (i) for the Company

to amend or terminate this Agreement, (ii) to exercise or waive any of the Company’s rights, benefits or remedies hereunder, if such action would materially and adversely affect the holders of Shares (other than Parent or Purchaser), (iii) to amend the Company Governing Documents if such action would materially and adversely affect the holders of Shares (other than Parent or Purchaser) or (iv) to take any other action of the Company Board of Directors under or in connection with this Agreement if such action would materially and adversely affect the holders of Shares (other than Parent or Purchaser); provided, however, that if there shall be no Continuing Directors as a result of such Persons’ deaths, disabilities or refusal to serve, then such actions may be effected by majority vote of the entire Company Board of Directors.

Section 1.4 The Merger.

Parent, Purchaser and their counsel shall be given a reasonable opportunity to review any such written responses and the Company shall give due consideration to all reasonable additions, deletions or changes suggested thereto by Parent, Purchaser and their counsel. The Company, on the one hand, and Parent and Purchaser, on the other hand, agree to promptly correct any information provided by it for use in the Proxy Statement if and to the extent that it shall have become false or misleading in any material respect or as otherwise required by applicable law and, the Company further agrees to cause the Proxy Statement, as so corrected (if applicable), to be filed with the SEC and, if any such correction is made following the mailing of the Proxy Statement as provided in Section 1.9(b)(ii), mailed to holders of Shares, in each case as and to the extent required by the Exchange Act or the SEC (or its staff).

(b) The Company, acting through the Company Board of Directors, shall, in accordance with and subject to the requirements of applicable law:

(i) (A) as promptly as practicable following the Appointment Time and the expiration of any “subsequent offering period” provided by Purchaser pursuant to and in accordance with this Agreement, if applicable, duly set a record date for, call and give notice of a special meeting of its stockholders (the “Special Meeting”) for the purpose of considering and taking action upon this Agreement (with the record date and meeting date set in consultation with Purchaser), and (B) as promptly as practicable following the Appointment Time and the expiration of any “subsequent offering period” provided by Purchaser pursuant to and in accordance with this Agreement, if applicable, convene and hold the Special Meeting;

(ii) cause the definitive Proxy Statement to be mailed to its stockholders; and

(iii) use its reasonable best efforts to (A) solicit from its stockholders proxies in favor of the adoption of this Agreement and (B) secure any approval of stockholders of the Company that is required by the DGCL and any other applicable law to effect the Merger.

(c) At the Special Meeting or any postponement or adjournment thereof, Parent shall vote, or cause to be voted, all of the Shares then owned by it, Purchaser or any of their other subsidiaries and affiliates in favor of the adoption of this Agreement and to deliver or provide, in its capacity as a stockholder of the Company, any other approvals that are required by the DGCL and any other applicable law to effect the Merger.

Section 1.10 Merger Without Meeting of Stockholders. Notwithstanding the terms of Section 1.9, in the event that Parent, Purchaser and their respective subsidiaries and affiliates shall hold, in the aggregate, at least ninety percent (90%) of the outstanding shares of each class of capital stock of the Company entitled to vote on the adoption of this Agreement under the DGCL (the “Short Form Threshold”), following the Appointment Time and the expiration of any “subsequent offering period” provided by Purchaser pursuant to and in accordance with this Agreement, if applicable, and the exercise of the 90% Top-Up Option, if applicable, Parent shall cause the Merger to become effective as promptly as practicable, without a meeting of stockholders of the Company, in accordance with Section 253 of the DGCL.

ARTICLE II

CONVERSION OF SECURITIES

Section 2.1 Conversion of Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holders of any securities of the Company or common stock, par value $0.0001 per share, of Purchaser (the “Purchaser Common Stock”):

(a) Purchaser Common Stock. Each issued and outstanding share of Purchaser Common Stock shall be converted into and become one fully paid and nonassessable share of common stock, par value $0.0001 per share, of the Surviving Corporation.

(b) Cancellation of Treasury Stock and Parent-Owned Stock. All Shares that are owned by the Company and any Shares owned by Parent, Purchaser or any of their respective subsidiaries or affiliates shall be cancelled and shall cease to exist, and no consideration shall be delivered in exchange therefor.

(c) Conversion of Common Stock. Each issued and outstanding Share (other than Shares to be cancelled in accordance with Section 2.1(b) and other than Dissenting Shares) shall be converted into the right to receive the Offer Price, payable to the holder thereof in cash, without interest (the “Merger Consideration”). From and after the Effective Time, all such Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each holder of a certificate representing any such Shares shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration therefor upon the surrender of such certificate in accordance with Section 2.2, without interest thereon.

(d) Adjustment to Merger Consideration. The Merger Consideration shall be adjusted appropriately to reflect the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Common Stock), cash dividend, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to Common Stock occurring on or after the date hereof and prior to the Effective Time.

Section 2.2 Exchange of Certificates.

(a) Paying Agent. Purchaser shall designate a bank or trust company to act as the payment agent in connection with the Merger (the “Paying Agent”). Prior to the Effective Time, Parent or Purchaser shall deposit, or cause to be deposited, with the Paying Agent the aggregate Merger Consideration. Such funds shall be invested by the Paying Agent as directed by Parent, in its sole discretion, pending payment thereof by the Paying Agent to the holders of the Shares. Earnings from such investments shall be the sole and exclusive property of Parent, and no part of such earnings shall accrue to the benefit of holders of Shares.

(b) Exchange Procedures. Promptly after the Effective Time, the Paying Agent shall mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding Shares (the “Certificates”) and whose Shares were converted pursuant to Section 2.1 into the right to receive the Merger Consideration (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Paying Agent and shall be in such form and have such other provisions as Parent may reasonably specify) and (ii) instructions for effecting the surrender of the Certificates in exchange for payment of the Merger Consideration. Upon surrender of a Certificate for cancellation to the Paying Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration for each Share formerly represented by such Certificate and the Certificate so surrendered shall forthwith be cancelled. If payment of the Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate is registered, it shall be a condition precedent of payment that (x) the Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and (y) the Person requesting such payment shall have paid any transfer and other similar taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate surrendered or shall have established to the satisfaction of the Surviving Corporation that such tax either has been paid or is not required to be paid. Until surrendered as contemplated by this Section 2.2, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration in cash as contemplated by this Section 2.2, without interest thereon.

(c) Transfer Books; No Further Ownership Rights in Shares. At the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of Shares on the records of the Company. From and after the Effective Time, the holders of Certificates outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares except as otherwise provided for herein or by applicable law. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be cancelled and exchanged as provided in this Article II.

(d) Termination of Fund; No Liability. At any time following six months after the Effective Time, the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any funds (including any interest received with respect thereto) made available to the Paying Agent and not disbursed (or for which disbursement is pending subject only to the Paying Agent’s routine administrative procedures) to holders of Certificates, and thereafter such holders shall be entitled to look only to 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, without any interest thereon. Notwithstanding the foregoing, neither the Surviving Corporation nor the Paying Agent shall be liable to any holder of a Certificate for Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

(e) Withholding Rights. Parent, Purchaser, the Surviving Corporation and the Paying Agent, as the case may be, shall be entitled to deduct and withhold from the relevant Merger Consideration or Offer Price otherwise payable pursuant to this Agreement to any holder of Shares such amounts that Parent, Purchaser, the Surviving Corporation or the Paying Agent is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), the rules and regulations promulgated thereunder or any provision of applicable state, local or foreign law. To the extent that amounts are so withheld by Parent, Purchaser, the Surviving Corporation or the Paying Agent, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Shares in respect of which such deduction and withholding was made by Parent, Purchaser, the Surviving Corporation or the Paying Agent.

(f) Lost, Stolen or Destroyed Certificates. In the event that any Certificates shall have been lost, stolen or destroyed, the Paying Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, the Merger Consideration payable in respect thereof pursuant to Section 2.1 hereof; provided, however, that Parent may, in its discretion and as a condition precedent to the payment of such Merger Consideration, require the owners of such lost, stolen or destroyed Certificates to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Parent, the Surviving Corporation or the Paying Agent with respect to the Certificates alleged to have been lost, stolen or destroyed.

Section 2.3 Dissenting Shares.

(a) Notwithstanding anything in this Agreement to the contrary, Shares outstanding immediately prior to the Effective Time and held by a holder who is entitled to demand and properly demands appraisal of such Shares (“Dissenting Shares”) pursuant to, and who complies in all respects with, Section 262 of the DGCL (the “Appraisal Rights”) shall be entitled to payment of the fair value of such Dissenting Shares in accordance with the Appraisal Rights; provided, however, that if any such holder shall fail to perfect or

otherwise shall waive, withdraw or lose the right to dissent under the Appraisal Rights, then the right of such holder to be paid the fair value of such holder’s Dissenting Shares shall cease and such Dissenting Shares shall be deemed to have been converted as of the Effective Time into, and to have become exchangeable solely for the right to receive the Merger Consideration.

(b) The Company shall serve prompt notice to Purchaser of any demands received by the Company for dissenter’s rights of any Shares, and Purchaser shall have the right to participate in all negotiations and proceedings with respect to such demands. Prior to the Effective Time, the Company shall not, without the prior written consent of Purchaser, make any payment with respect to, or settle or compromise or offer to settle or compromise, any such demand, or agree to do any of the foregoing.

Section 2.4 Top-Up Options.

(a) 90% Top-Up Option.

(i) The Company hereby grants to Purchaser an irrevocable option (the “90% Top-Up Option”), exercisable only upon the terms and subject to the conditions set forth herein, to purchase with a promissory note, bearing simple interest at 6% per annum, and due 30 days after the purchase (a “Promissory Note”), at a price per share equal to the Offer Price, that number of shares of Common Stock (the “90% Top-Up Option Shares”) equal to the lesser of (x) the lowest number of shares of Common Stock that, when added to the number of shares of Common Stock owned by Parent, Purchaser and their respective subsidiaries and affiliates at the time of such exercise, shall constitute ten thousand (10,000) shares more than 90% of the shares of Common Stock then outstanding (after giving effect to the issuance of the 90% Top-Up Option Shares) and (y) an aggregate number of shares of Common Stock that is equal to 19.9% of the shares of Common Stock issued and outstanding as of the date hereof; provided, however, that the 90% Top-Up Option shall not be exercisable unless, immediately after such exercise and the issuance of shares of Common Stock pursuant thereto, the Short Form Threshold would be reached (assuming the issuance of the 90% Top-Up Option Shares); and provided, further, that in no event shall the 90% Top-Up Option be exercisable for a number of shares of Common stock in excess of the Company’s total authorized and unissued shares of Common Stock.

(ii) Provided that no applicable law, rule, regulation, order, injunction or other legal impediment shall prohibit the exercise of the 90% Top-Up Option or the issuance of the 90% Top-Up Option Shares pursuant thereto, or otherwise make such exercise or issuance illegal, Purchaser may exercise the 90% Top-Up Option, in whole but not in part, at any one time after the Appointment Time and prior to the earlier to occur of (i) the Effective Time and (ii) the termination of this Agreement pursuant to Section 8.1.

(iii) In the event Purchaser wishes to exercise the 90% Top-Up Option, Purchaser shall send to the Company a written notice (a “90% Top-Up Exercise Notice,” the date of which notice is referred to herein as the “90% Top-Up Notice Date”) specifying the denominations of the certificate or certificates evidencing the 90% Top-Up Option Shares which the Purchaser wishes to receive, and the place, time and date for the closing of the purchase and sale pursuant to the 90% Top-Up Option (the “90% Top-Up Closing”). The Company shall, promptly after receipt of the 90% Top-Up Exercise Notice, deliver a written notice to the Purchaser confirming the number of 90% Top-Up Option Shares and the aggregate purchase price therefore (the “90% Top-Up Notice Receipt”). At the 90% Top-Up Closing, Purchaser shall pay the Company the aggregate price required to be paid for the 90% Top-Up Option Shares, by delivery of a Promissory Note in an aggregate principal amount equal to the amount specified in the 90% Top-Up Notice Receipt, and the Company shall cause to be issued to Purchaser a certificate or certificates representing the 90% Top-Up Option Shares. Such certificates may include any legends that are required by federal or state securities laws.

(b) 50% Top-Up Option.

(i) In order to offset the dilutive impact of the issuance of Shares pursuant to the exercise, conversion or exchange of any Company Options, SARs, RSUs, Warrants, Equity Interests or other rights to acquire Shares following the Appointment Time, the Company hereby grants to Purchaser an irrevocable option (the “50% Top-Up Option”), exercisable only upon the terms and subject to the conditions set forth herein, to purchase with a Promissory Note, at a price per share equal to the Offer Price, that number of shares of Common Stock (the “50% Top-Up Option Shares”) equal to the lesser of (x) the lowest number of shares of Common Stock that, when added to the number of shares of Common Stock owned by Parent, Purchaser and their respective subsidiaries and affiliates at the time of such exercise, shall constitute ten thousand (10,000) shares more than 50% of the shares of Common Stock then outstanding (after giving effect to the issuance of the 50% Top-Up Option Shares) and (y) an aggregate number of shares of Common Stock that is equal to 19.9% of the shares of Common Stock issued and outstanding as of the date hereof; provided, however, that the 50% Top-Up Option shall not be exercisable unless, immediately after such exercise and the issuance of shares of Common Stock pursuant thereto, Purchaser would own more than 50% of the Shares then outstanding (assuming the issuance of the 50% Top-Up Option Shares); and provided, further, that in no event shall the 50% Top-Up Option be exercisable for a number of shares of Common stock in excess of the Company’s total authorized and unissued shares of Common Stock.

(ii) Provided that no applicable law, rule, regulation, order, injunction or other legal impediment shall prohibit the exercise of the 50% Top-Up Option or the issuance of the 50% Top-Up Option Shares pursuant thereto, or otherwise make such exercise or issuance illegal, Purchaser may exercise the 50% Top-Up Option, in whole but not in part, at any one time after the Appointment Time and prior to the earlier to occur of (i) the record date for the Special Meeting, and (ii) the termination of this Agreement pursuant to Section 8.1.

(iii) In the event Purchaser wishes to exercise the 50% Top-Up Option, Purchaser shall send to the Company a written notice (a “50% Top-Up Exercise Notice,” the date of which notice is referred to herein as the “50% Top-Up Notice Date”) specifying the denominations of the certificate or certificates evidencing the 50% Top-Up Option Shares which the Purchaser wishes to receive, and the place, time and date for the closing of the purchase and sale pursuant to the 50% Top-Up Option (the “50% Top-Up Closing”). The Company shall, promptly after receipt of the 50% Top-Up Exercise Notice, deliver a written notice to the Purchaser confirming the number of 50% Top-Up Option Shares and the aggregate purchase price therefore (the “50% Top-Up Notice Receipt”). At the 50% Top-Up Closing, Purchaser shall pay the Company the aggregate price required to be paid for the 50% Top-Up Option Shares by delivery of a Promissory Note in an aggregate principal amount equal to the aggregate purchase price specified in the 50% Top-Up Notice Receipt, and the Company shall cause to be issued to Purchaser a certificate or certificates representing the 50% Top-Up Option Shares. Such certificates may include any legends that are required by federal or state securities laws.

Section 2.5 Treatment of Options, Restricted Stock and other Equity Awards.

(a) At the Effective Time, each option, or portion thereof, to purchase Shares granted pursuant to the Company Stock Plans (“Company Options”) or stock appreciation right, or portion thereof, whether settled in cash or Shares (“SAR”), in each case granted pursuant to the Company Stock Plans, that is outstanding and vested immediately prior to the Effective Time, shall be deemed exercised and automatically converted into the right to receive an amount in cash equal to the product obtained by multiplying (x) the aggregate number of Shares for which such Company Option or SAR was vested and exercisable immediately prior to the Effective Time and (y) the excess, if any, of the Merger Consideration less the per Share exercise price of such Company Option or SAR (the “Option Consideration”) after which it shall be cancelled and extinguished.

(b) At the Effective Time, each Company Option and SAR that was outstanding and unvested immediately prior to the Effective Time shall be assumed by the Parent and converted into the right to receive the Option Consideration, provided that the Company Option or SAR shall be subject to the same vesting arrangements that were applicable to such Company Option or SAR immediately prior to the Effective Time and Parent’s obligation to pay the Option Consideration will only become payable to the extent that such vesting requirements are satisfied. For each Share subject to a Company Option or SAR which would have vested after the Effective Time under the vesting schedule applicable to such Company Option or SAR immediately prior to the Effective Time, the holder thereof shall be entitled to a cash payment equal to the Option Consideration, and Parent shall pay the holder thereof the Option Consideration as soon as administratively practicable after the day on which such Share would have vested.

(c) At the Effective Time, the Merger Consideration payable with respect to each unvested Share subject to restrictions and forfeiture granted pursuant to the Company Stock Plans (“Restricted Stock”) shall be subject to the same restrictions and vesting arrangements that were applicable to such unvested Restricted Stock immediately prior to the Effective Time. Therefore, cash otherwise payable pursuant to Section 2.1 in exchange for the Restricted Stock issued and outstanding immediately prior to the Effective Time (“Unvested Cash”) shall not automatically be payable by Parent at the Effective Time, and shall instead become payable by Parent on the date that such Shares of Restricted Stock would have become vested under the vesting schedule in place for such shares immediately prior to or at the Effective Time (subject to the restrictions and other terms of such vesting schedule). Parent shall make all such required payments to holders of Unvested Cash as soon as administratively practicable after the day on which such Unvested Cash would have become vested under the original vesting schedule. All outstanding rights to repurchase Restricted Stock that the Company may hold or similar restrictions in the Company’s favor immediately prior to the Effective Time (all such rights, the “Repurchase Rights”) shall be assigned to Parent in the Merger and shall thereafter be exercisable by Parent upon the same terms and subject to the same conditions that were in effect immediately prior to the Effective Time, except that Repurchase Rights may be exercised by Parent retaining the Unvested Cash into which such Restricted Stock has been converted, and paying to the former holder thereof the repurchase price in effect for each such Share subject to that Repurchase Right immediately prior to the Effective Time.

(d) At the Effective Time, each Share subject to a Restricted Stock Unit granted pursuant to the Company Stock Plans (“RSU”) that is outstanding immediately prior to the Effective Time will be assumed by the Parent and converted into the potential right to receive a cash payment equal to the Merger Consideration (the “RSU Consideration”); provided, however, that the RSU shall be subject to the same vesting arrangements that were applicable immediately prior to the Effective Time and payment of the RSU Consideration with respect to a Share subject to an RSU will only become payable by the Parent to the extent that such vesting requirements are satisfied. For each Share subject to an RSU which would have vested after the Effective Time, the holder thereof shall be entitled to a cash payment equal to the RSU Consideration, and Parent shall pay the holder thereof the RSU Consideration as soon as administratively practicable after the day on which such Share subject to the RSU would have vested.

(e) The Company shall take all necessary actions, including obtaining any required consents from holders of outstanding Company Options, SARs, Restricted Stock and RSUs necessary to effect the transactions described in Sections 2.5(a)-(d) above pursuant to the terms of the applicable Company Stock Plans and agreements evidencing the Company Options, SARs Restricted Stock and RSUs. All amounts payable pursuant to Sections 2.5(a)-(d) shall be paid without interest, and no Unvested Cash or RSU Consideration or rights to receive any payments pursuant to Section 2.5(c) and (d) may be pledged, encumbered, sold, assigned or transferred (including any transfer by operation of law), by any Person, other than Parent, or be taken or reached by any legal or

equitable process in satisfaction of any liability of such Person, prior to the distribution to such Person of such Unvested Cash or RSU Consideration or payment pursuant to Section 2.5(c) and (d), in accordance with this Agreement. Any payments made pursuant to this Section 2.5 shall be net of all applicable withholding taxes that Parent, Purchaser, the Surviving Corporation and the Paying Agent, as the case may be, shall be required to deduct and withhold from the relevant Option Consideration, Unvested Cash, RSU Consideration, or Merger Consideration under the Code, the rules and regulations promulgated thereunder or any provision of applicable state, local or foreign law. To the extent that amounts are so withheld by Parent, Purchaser, the Surviving Corporation or the Paying Agent, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Shares in respect of which such deduction and withholding was made by Parent, Purchaser, the Surviving Corporation or the Paying Agent.

Section 2.6 Treatment of Employee Stock Purchase Plan. Each outstanding purchase right (each, a “Purchase Right”) under the Company’s 1999 Employee Stock Purchase Plan (the “ESPP”) shall be cancelled immediately prior to the Effective Time and converted into the right to receive at the Effective Time from Parent, an amount (subject to any withholding tax required by applicable law) in cash equal to the product obtained by multiplying (x) the number of Shares issuable to the holder of such Purchase Right had such Purchase Right been exercised immediately prior to the Effective Time and (y) the amount by which the Merger Consideration exceeds the purchase price under such Purchase Right. Within five (5) days following the Effective Time, Parent shall cause the Company to return to participants their respective accumulated payroll contributions not applied to the purchase of Shares under the ESPP, if any.

Section 2.7 Treatment of Warrants. At the Effective Time, each warrant to purchase Shares (the “Warrants”) that is issued and outstanding immediately prior to the Effective Time and not terminated pursuant to its terms shall be assumed by Parent and converted into the right to receive cash equal to the product obtained by multiplying (x) the aggregate number of Shares for which such Warrant was exercisable immediately prior to the Effective Time and (y) the excess, if any, of the Merger Consideration less the per Share exercise price of such Warrant (the “Warrant Consideration”). The Company shall take all necessary actions, including obtaining any required consents from holders of outstanding Warrants necessary to effect such assumption pursuant to the terms of the applicable Warrant. Any payments made pursuant to this Section 2.7 shall be net of all applicable withholding taxes that Parent, Purchaser, the Surviving Corporation and the Paying Agent, as the case may be, shall be required to deduct and withhold from the Warrant Consideration under the Code, the rules and regulations promulgated thereunder or any provision of applicable state, local or foreign law. To the extent that amounts are so withheld by Parent, Purchaser, the Surviving Corporation or the Paying Agent, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Warrants in respect of which such deduction and withholding was made by Parent, Purchaser, the Surviving Corporation or the Paying Agent.

(g) Section 3.11(g) of the Company Disclosure Schedule discloses each Benefit Plan that is an employee welfare benefit plan which is (i) unfunded or self-insured or (ii) funded through a “welfare benefit fund”, as such term is defined in Code Section 419(e)

or other funding mechanism. Except as has not had and would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect, each such employee welfare benefit plan may be amended or terminated (including with respect to benefits provided to retirees and other former employees) without liability (other than benefits then payable under such plan without regard to such amendment or termination) to the Company or any Company Subsidiary at any time.

Neither this Agreement (or the consummation of the Transactions contemplated hereby) nor any other agreement, plan, arrangement or other contract between the Company or any Company Subsidiary and an employee or other service provider that, considered individually or considered collectively with any other such agreements, plans, arrangements or other contracts, could reasonably be expected to, give rise directly or indirectly to the payment of any amount that would be characterized as an “excess parachute payment” within the meaning of Section 280G(b)(1) of the Code.

(m) All Company Options have been appropriately authorized by the Company’s Board of Directors or an appropriate committee thereof, including approval of the option exercise price or the methodology for determining the option exercise price and the substantive option terms.

All material Taxes due and owing by any of the Company and each Company Subsidiary on or before the date hereof (whether or not shown on any Tax Returns) have been paid, or both are being contested in good faith and have been reserved for in accordance with GAAP on the Financial Statements. None of the Company or any Company Subsidiary currently is the beneficiary of any extension of time within which to file any material Tax Return.

Neither the Company nor any of the Company Subsidiaries nor any predecessor has waived any statute of limitations in respect of material Taxes or agreed to any extension of time with respect to a material Tax assessment or deficiency, nor has any request been made in writing for any such extension or waiver.

(d) There are no Liens for Taxes upon the assets of any of the Company and the Company Subsidiaries (other than with respect to Liens for Taxes (i) not yet due and payable or (ii) being contested in good faith and for which adequate reserves have been established in accordance with GAAP on the Financial Statements).

(e) None of the Company nor any of the Company Subsidiaries has been a United States real property holding corporation within the meaning of Section 897(c)(2) of the Code during the applicable period specified in Section 897(c)(1)(A)(ii) of the Code.

(i) Neither the Company nor any of the Company Subsidiaries has constituted a “distributing corporation” or a “controlled corporation” (within the meaning of Section 355(a)(1)(A) of the Code) in a distribution of stock to which Section 355 of the Code (or so much of Section 356 of the Code as relates to Section 355 of the Code) applies.

(j) Neither the Company nor any of the Company Subsidiaries (i) has agreed, or is required, to make any adjustment under Section 481(a) of the Code for any period after the Closing Date by reason of a change in accounting method or otherwise; or (ii) is a shareholder of a “passive foreign investment company” within the meaning of Section 1297 of the Code.

(b) Section 3.15(b) of the Company Disclosure Schedule contains a complete and accurate list of all Company Agreements that are material to the Company, in effect as of the date hereof, in each case specifying the date of and parties to the agreement and whether such agreement is exclusive or non-exclusive, (i) under which the Company or any of its Subsidiaries uses or has the right to use any Licensed Company IP, other than non-exclusive licenses and related services agreements for generally commercially

Neither the Company nor any of its Subsidiaries has granted any exclusive license under any Owned Company IP. To the knowledge of the Company, there are no pending disputes regarding the scope of any Company IP Agreements, performance under any Company IP Agreements, or with respect to payments made or received under any Company IP Agreements, except where such disputes have not had and would not have, individually or in the aggregate, a Company Material Adverse Effect.

No Governmental Entity has any ownership interest in any Owned Company IP, and neither Company nor its Subsidiaries use or have used any funding, facilities, or personnel of any Governmental Entity in connection with the creation of the Owned Company IP in a manner that could give rise to an ownership interest in the Owned Company IP in favor of such Governmental Entity.

To the Company’s knowledge, all use and disclosure by the Company or any of its Subsidiaries of Trade Secrets owned by another Person has been pursuant to the terms of a

written agreement with such Person permitting such use or was otherwise lawful, except to the extent that any such use or disclosure that was not done in accordance with such a written agreement does not and will not, individually or in the aggregate, give rise to a Company Material Adverse Effect. The Company and its Subsidiaries have executed confidentiality agreements with all employees and contractors to whom the Company or its Subsidiaries have granted access to Trade Secrets, which agreements prohibit such employees and contractors from disclosing such Trade Secrets to third parties or using such Trade Secrets for any purpose other than for the benefit of the Company or its Subsidiaries.

To the knowledge of the Company as of the date hereof, no Person or any of such Person’s products or services or other operation of such Person’s business is infringing upon or otherwise violating any Owned Company IP in any material respect.

(h) No action, claim or proceeding alleging infringement, misappropriation, or other violation of any Intellectual Property Right of another Person is pending or, to the knowledge of the Company, has been threatened against Company or its Subsidiaries. Neither the Company nor any of its Subsidiaries has received any notice or other communication relating to any actual, alleged, or suspected infringement, misappropriation, or violation of any Intellectual Property Right of another Person by Company or any Subsidiary. The Company and its Subsidiaries are not subject to any Order of any Governmental Entity that restricts or impairs the use of any Company IP.

(i) The execution and delivery of this Agreement and the consummation of the Transactions will not (with or without notice or the lapse of time, or both) automatically result in (i) the Company or its Subsidiaries granting to any third party any rights or licenses to any Intellectual Property or Intellectual Property Rights, (ii) any right, including any right of termination, amendment, modification, cancellation or acceleration under any Company IP Agreement, (iii) the loss of or the imposition of any Lien on any Owned Company IP, (iv) the release, disclosure, or delivery of any Owned Company IP by or to any escrow agent or other Person; or (v) after the Merger, Parent or any of its Subsidiaries being required, under the terms of any agreement to which the Company or any of its Subsidiaries is a party, to grant any Person any rights or licenses to any of Parent’s or any of its Subsidiaries’ Intellectual Property or Intellectual Property Rights.

(j) No software incorporated in any Company Product is subject to any “copyleft” or other obligation or condition (including any obligation or condition under any “open source” license such as the GNU Public License, Lesser GNU Public License, or Mozilla Public License) that (i) could require, or could condition the use or distribution of any software contained in any Company Product on, the disclosure, licensing, or distribution of any source code for any portion of Owned Company IP in a Company Product, or (ii) could otherwise impose any limitation, restriction, or condition on the right or ability of the Company or its Subsidiaries to use or distribute any software contained in any Company Product.

Neither the Company nor any of its Subsidiaries has provided or licensed, or has any duty or obligation (whether present, contingent, or otherwise) to provide or license, Company Source Code to any escrow agent or other third party. No event has occurred, and no circumstance or condition exists, that (with or without notice or lapse of time) will, or could reasonably be expected to, result in the provision, license, or disclosure of any Company Source Code to any third party.

(l) The Company’s and its Subsidiaries’ collection and dissemination of personal information in connection with their business has been conducted in accordance with applicable privacy policies published or otherwise adopted by the Company and its Subsidiary and any applicable laws and regulations, except where the failure to abide by any such policy or law would not, individually or in the aggregate, reasonably be expected to give rise to a Company Material Adverse Effect.

(d) The Surviving Corporation shall maintain and extend all existing officers’ and directors’ liability insurance (“D&O Insurance”) for a period of not less than six (6) years after the Effective Time with respect to claims arising in whole or in part from facts or events that actually or allegedly occurred on or before the Effective Date, including in connection with the approval of this Agreement and the Transactions; provided, however, that Parent may substitute therefor policies of substantially equivalent coverage and amounts containing terms no less favorable to the Covered Persons than the existing D&O Insurance; provided, further, that if the existing D&O Insurance expires or is terminated or cancelled during such period through no fault of Parent or the Surviving Corporation, the Surviving Corporation shall obtain substantially similar D&O Insurance; provided further, however, that in no event shall Parent be required to pay aggregate premiums for insurance under this Section 6.5(d) in excess of 200% of the aggregate premiums paid by the Company in 2006 for such purpose (the “Base Premium”), the true and correct amount of which is set forth in Section 6.5(d) of the Company Disclosure Schedule; and provided, further, that if Parent or the Surviving Corporation is unable to obtain the amount of insurance required by this Section 6.5(d) for such aggregate premium, Parent or the Surviving Corporation shall obtain as much insurance as can be obtained for aggregate premiums not in excess of 200% of the Base Premium. In lieu of the foregoing, the Company may obtain prepaid policies prior to the Effective Time, which policies may provide the Covered Persons with D&O Insurance coverage of equivalent amount and on no more favorable terms than that provided by the Company’s current D&O Insurance for an aggregate period of at least six (6) years with respect to claims arising from facts or events that occurred on or before the Effective Time, including in connection with the approval of this Agreement and the Transactions contemplated hereby. If such prepaid policies have been obtained prior to the Effective Time, Parent and the Surviving Corporation shall be relieved of all further obligations under this Section 6.5(d); provided, that Parent and the Surviving Corporation shall maintain such policies in full force and effect, and continue to honor its obligations thereunder.

(e) In the event the Surviving Corporation or any of its 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 such continuing or surviving corporation or entity or transferee of such assets, as the case may be, shall assume all of the applicable obligations set forth in this Section 6.5.

(f) The Covered Persons (and their successors and heirs) are intended third party beneficiaries of this Section 6.5, and this Section 6.5 shall not be amended in a manner that is adverse to the Covered Persons (including their successors and heirs) or terminated without the consent of the Covered Persons (including their successors and heirs) affected thereby.

Section 6.6 State Takeover Laws. If any “control share acquisition”, “fair price” or other anti-takeover laws or regulations enacted under state or federal laws becomes or is deemed to become applicable to the Company, the Offer, the acquisition of Shares pursuant to the Offer, the Merger, the Support Agreements or any other Transaction, then the Company Board of Directors shall take all action necessary to render such statute inapplicable to the foregoing.

Section 6.7 Certain Tax Matters. During the period from the date hereof to the Effective Time, the Company shall and shall cause each of the Company Subsidiaries to: (i) timely file all material Tax Returns required to be filed by the Company or such Company Subsidiary, as the case may be, and prepare such Tax Returns in all material respects in a manner consistent with past practice, (ii) timely pay all material Taxes due and payable by the Company and such Company Subsidiary, respectively, except for such Taxes contested in good faith and for which an adequate reserve has been established in accordance with GAAP on the appropriate financial statements and (iii) promptly notify Parent of any federal or state income or franchise, or other material Tax, suit claim, action, investigation, proceeding or audit pending against or with respect to the Company or any Company Subsidiary in respect of any Tax matters (or any significant developments with respect to ongoing Tax matters), including without limitation material Tax liabilities and material refund claims.

Section 6.8 Rights Agreement; Consequences if Rights Triggered. The Company Board of Directors shall take all action requested in writing by Parent or Purchaser in order to render the Company Rights inapplicable to the Offer, the Merger, the Support Agreements and the other Transactions. Except as approved in writing by Parent, the Company Board shall not (i) amend the Company Rights Agreement, (ii) redeem the Company Rights or (iii) take any action with respect to, or make any determination under, the Company Rights Agreement, in each case in a manner adverse to Parent or Purchaser. If any Distribution Date, Stock Acquisition Date or Flip-In Event occurs under the Company Rights Agreement at any time during the period from the date of this Agreement to the Effective Time, the Company and Parent shall make such adjustment to the Offer Price as the Company and Parent shall mutually agree so as to preserve the economic benefits that the Company and Parent each reasonably expected on the date of this Agreement to receive as a result of the consummation of the Offer, the Merger and the other Transactions.

Section 6.9 Section 16. The Company Board of Directors shall, to the extent necessary, take appropriate action, prior to or as of the Effective Time, to approve, for purposes of Section 16(b) of the Exchange Act, the deemed disposition and cancellation of the vested Company Options in the Merger. Provided that Company shall first provide to Parent the names of its stockholders and the number of shares of Common Stock or Company Options which may be subject to Section 16(b) of the Exchange Act and any other

information reasonably requested by Parent and relating to the same, the Board of Directors of Parent, or an authorized committee thereof, shall, prior to the Effective Time, take appropriate action to approve, for purposes of Section 16(b) of the Exchange Act, the issuance of the Merger Consideration to holders of Company Options in accordance with Section 2.5.

Section 6.10 Obligations of Purchaser.

Section 6.11 Employee Benefits Matters. Except as provided in the last sentence of this Section 6.11, Parent and the Surviving Corporation shall have no obligation to continue after the Effective Time any plan or arrangement in effect immediately before the Effective Time (except as otherwise required by applicable law, including without limitation ERISA and the Code) for current or former employees, officers or directors of the Company or any Subsidiary, and shall have the discretion to continue or terminate any of such programs, or to merge any of them into plans or arrangements in effect for other employees of Parent or the Surviving Corporation. To the extent legally permitted, employees of the Company or any Subsidiary shall receive credit for purposes of eligibility to participate and vesting under any employee pension benefit plan, program or arrangement established or maintained by the Surviving Corporation or any of its Subsidiaries and for the purpose of eligibility and determining the amount of any benefit with respect to any employee welfare benefit plan, program or arrangement established or maintained by the Surviving Corporation for service accrued or deemed accrued prior to the Effective Time with the Company or any Subsidiary; provided, however, that such crediting of service shall not operate to duplicate any benefit or the funding of any such benefit. Parent shall also cause the Surviving Corporation to perform the Company’s obligations under the change in control and other agreements set forth in the Company Disclosure Schedule between the Company and certain of its officers and employees unless any such officer or employee agrees otherwise.

Section 6.12 Termination of 401(k) Plan. Unless Parent directs the Company otherwise in writing no later than five (5) business days prior to the Effective Time, the Company Board of Directors shall adopt resolutions terminating, effective at least two (2) days prior to the Effective Time, any Benefit Plan which is intended to meet the requirements of section 401(k) of the Code (each such Benefit Plan, a “401(k) Plan”). At the Closing, the Company shall provide Parent with (i) executed resolutions of the Company Board of Directors authorizing such termination and (ii) an executed copy of any necessary amendment to each such 401(k) Plan in a form reasonably satisfactory to Parent that is intended to assure compliance with all applicable requirements of the Code and the regulations thereunder.

(i) if a court of competent jurisdiction or other Governmental Entity shall have issued a final, non-appealable order, decree or ruling in each case permanently restraining, enjoining or otherwise prohibiting the Transactions; or

(ii) by mutual written consent of Parent and the Company duly authorized by the Company Board of Directors and the Parent Board of Directors, or authorized committee thereof.

Section 8.2 Effect of Termination.

(c) The Termination Fee shall be paid by wire transfer of immediately available funds to an account designated in writing by Parent. For the avoidance of doubt, in no event shall the Company be obligated to pay the Termination Fee on more than one occasion.

Section 9.12 Waiver of Jury Trial. EACH PARTY IS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE OFFER AND MERGER CONTEMPLATED HEREBY OR THEREBY.
