Section 1.3 Directors.

(a) Effective upon the Offer Closing and from time to time thereafter, Parent shall be entitled to designate the number of directors, rounded up to the next whole number, on the Board of Directors of the Company that equals the product of (i) the total number of directors on the Board of Directors of the Company (giving effect to the election of any additional directors pursuant to this Section 1.3) and (ii) the percentage that the number of Shares beneficially owned by Parent and/or Merger Sub (including Shares accepted for payment) bears

-5-

to the total number of Shares then outstanding, and the Company shall cause Parent’s designees to be elected or appointed to the Board of Directors of the Company, including by increasing the number of directors, seeking and accepting resignations of incumbent directors and taking all actions necessary in connection with accomplishing the foregoing, including amending the Company Bylaws. At such time, the Company shall also cause individuals designated by Parent to constitute the number of members, rounded up to the next whole number, on (A) each committee of the Board of Directors of the Company and (B) as requested by Parent, each board of directors (or similar governing body) of each Subsidiary of the Company (and each committee thereof) that represents the same percentage as such individuals represent on the Board of Directors of the Company.

(b) The Company’s obligations to appoint Parent’s designees to the Board of Directors of the Company shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder. The Company shall promptly take all actions necessary to effect the appointment of Parent’s designees, including mailing to its stockholders information with respect to the Company and its officers and directors, as Section 14(f) and Rule 14f-1 require in order to fulfill its obligations under this Section 1.3(b), which, unless Parent otherwise elects, shall be mailed together with the Schedule 14D-9. Parent shall supply to the Company in writing and be solely responsible for any information with respect to itself and its nominees, officers, directors and affiliates required by Section 14(f) and Rule 14f-1 and the Company’s obligations under Section 1.3(a) hereof shall be subject to the receipt of such information.

(c) Following the election or appointment of Parent’s designees pursuant to Section 1.3(a) and until the Effective Time, the approval of a majority of the directors of the Company then in office who were not designated by Parent (the “Independent Directors”) shall be required to authorize (and such authorization shall constitute the authorization of the Board of Directors of the Company and no other action on the part of the Company, including any action by any other director of the Company, shall be required to authorize) (i) any termination of this Agreement by the Company, (ii) any amendment of this Agreement requiring action by the Board of Directors of the Company, (iii) any extension of time for performance of any obligation or action hereunder by Parent or Merger Sub, and (iv) any waiver of compliance with any of the agreements or conditions contained herein for the benefit of the Company.

Section 1.4 Top-Up Option.

(a) The Company hereby grants to Merger Sub an irrevocable option (the “Top-Up Option”), exercisable only on the terms and conditions set forth in this Section 1.4, to purchase at a price per share equal to the Offer Price paid in the Offer up to that number of newly issued Shares (the “Top-Up Shares”) equal to the lowest number of Shares that, when added to the number of Shares owned by Parent and its Subsidiaries at the time of exercise of the Top-Up Option, shall constitute one share more than ninety percent (90%) of the Shares outstanding immediately after the issuance of the Top-Up Shares on a fully diluted basis (which assumes conversion or exercise of all derivative securities regardless of the conversion or exercise price, the vesting schedule or other terms and conditions thereof); provided, however, that (i) the Top-Up Option shall not be exercisable for a number of Shares in excess of the Shares authorized and unissued or held in the treasury of the Company at the time of exercise of the Top-Up Option (giving effect to the Shares issuable pursuant to all then-outstanding Company Stock Options

-6-

and Company RSUs and any other rights to acquire Company Common Stock as if such Shares were outstanding) and (ii) the exercise of the Top-Up Option and the issuance and delivery of the Top-Up Shares shall not be prohibited by any Law or Order. The Top-Up Option shall be exercisable only once, in whole but not in part, at any time following the Offer Closing and prior to the earlier to occur of (A) the Effective Time and (B) the termination of this Agreement in accordance with its terms.

(b) In the event Merger Sub wishes to exercise the Top-Up Option, Merger Sub shall give the Company at least three (3) Business Days prior written notice, specifying (i) the number of Shares owned by Parent and its Subsidiaries at the time of such notice (giving effect to the Offer Closing) and (ii) a place and a time for the closing of such purchase. The Company shall, as soon as practicable following receipt of such notice, deliver written notice to Merger Sub specifying, based on the information provided by Merger Sub in its notice, the number of Top-Up Shares to be purchased by Merger Sub. At the closing of the purchase of Top-Up Shares, the aggregate purchase price owed by Merger Sub to the Company for the Top-Up Shares shall be paid to the Company at Parent’s election, either (i) entirely in cash, by wire transfer of same-day funds or (ii) by (A) paying in cash by wire transfer of same-day funds an amount equal to not less than the aggregate par value of the Top-Up Shares and (B) issuing to the Company a promissory note having a principal amount equal to the aggregate purchase price pursuant to the Top-Up Option less the amount paid in cash pursuant to the preceding clause (A) (the “Promissory Note”). The Promissory Note shall bear interest at a rate per annum equal to the prime lending rate prevailing during the period in which any portion of the principal amount of such promissory note remains outstanding, as published by The Wall Street Journal, calculated on a daily basis on the outstanding principal amount of the Promissory Note from the date the Promissory Note is originally issued until the date of payment in full of the Promissory Note, and may be prepaid without premium or penalty. The Company shall cause to be issued to Merger Sub a certificate representing the Top-Up Shares or, if the Company does not then have certificated Shares, the applicable number of Book-Entry Shares. Such certificates or Book-Entry Shares may include any legends that are required by federal or state securities Laws.

(c) Parent and Merger Sub acknowledge that no Top-Up Shares issued upon exercise of the Top-Up Option will be registered under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (the “Securities Act”) and that all such Top-Up Shares will be issued in reliance upon an applicable exemption from registration under the Securities Act. Each of Parent and Merger Sub hereby represents and warrants to the Company that Merger Sub is, and will be, upon the purchase of the Top-Up Shares, an “accredited investor”, as defined in Rule 501 of Regulation D under the Securities Act. Merger Sub agrees that the Top-Up Option and the Top-Up Shares to be acquired upon exercise of the Top-Up Option are being and will be acquired by Merger Sub for the purpose of investment and not with a view to, or for resale in connection with, any distribution thereof (within the meaning of the Securities Act).

Section 3.1 Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the Company, Parent, Merger Sub or the holders of any securities of the Company, Parent or Merger Sub:

(a) Parent Common Stock. Each share of common stock, par value $1.00 per share, of Parent (the “Parent Common Stock”) issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding and shall not be affected by the Merger.

(b) Conversion of Company Common Stock. Subject to Sections 3.1(c) and 3.1(e), each issued and outstanding Share outstanding immediately prior to the Effective Time, other than (i) any Shares held by any direct or indirect wholly owned subsidiary of the Company, which Shares shall remain outstanding, except that the number of such shares owned by any such subsidiary of the Company shall be adjusted in the Merger to maintain relative ownership percentages (as adjusted, the “Remaining Shares”), (ii) any Cancelled Shares, and (iii) any Dissenting Shares, shall thereupon be converted automatically into and shall thereafter represent the right to receive an amount in cash equal to the Offer Price, without interest (the “Merger Consideration”). All Shares that have been converted into the right to receive the Merger Consideration as provided in this Section 3.1 shall be automatically cancelled and shall cease to exist, and the holders of certificates which immediately prior to the Effective Time represented such Shares shall cease to have any rights with respect to such Shares other than the right to receive the Merger Consideration.

(c) Parent and Merger Sub-Owned Shares. Each Share that is owned by Parent or Merger Sub immediately prior to the Effective Time, if any, or held by the Company immediately prior to the Effective Time (in each case, other than any such Shares held on behalf of third parties) (the “Cancelled Shares”) shall, by virtue of the Merger and without any action on the part of the holder thereof, be cancelled and retired and shall cease to exist, and no consideration shall be delivered in exchange for such cancellation and retirement.

(d) Conversion of Merger Sub Common Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, each share of common stock, par value $0.01, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one validly issued, fully paid and nonassessable share of common stock, par value $0.001, of the Surviving Corporation and shall with the Remaining Shares constitute the only outstanding shares of capital stock of the Surviving Corporation. From and after the Effective Time, all certificates representing the common stock of Merger Sub shall be deemed for all purposes to represent the number of shares of common stock of the Surviving Corporation into which they were converted in accordance with the immediately preceding sentence.

-9-

(e) Adjustments. If at any time during the period between the date of this Agreement and the Effective Time any change in the outstanding shares of capital stock of the Company, or in the securities convertible or exchangeable into or exercisable for shares of capital stock, shall occur as a result of any reclassification, recapitalization, stock split (including a reverse stock split) or subdivision or combination, exchange or readjustment of shares, or any stock dividend or stock distribution with a record date during such period, merger or other similar transaction, the Offer Price and the Merger Consideration (as applicable) shall be equitably adjusted to reflect such change; provided that nothing in this Section 3.1(e) shall be construed to permit the Company to take any action with respect to its securities that is prohibited by the terms of this Agreement.

(f) Dissenters’ Rights. Notwithstanding anything in this Agreement to the contrary, Shares that are issued and outstanding immediately prior to the Effective Time and which are held by a stockholder who did not vote in favor of the Merger (or consent thereto in writing) and who is entitled to demand and properly demands appraisal of such Shares pursuant to, and who complies in all respects with, the applicable provisions of Section 262 of the DGCL (the “Dissenting Stockholders”), shall not be converted into or be exchangeable for the right to receive the Merger Consideration (the “Dissenting Shares”), but instead such holder shall be entitled to payment for such Shares in accordance with the applicable provisions of the DGCL (and at the Effective Time, such Dissenting Shares shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and such holder shall cease to have any rights with respect thereto, except the right to receive the appraised value of such Dissenting Shares in accordance with the applicable provisions of the DGCL), unless and until such holder shall have failed to perfect or shall have effectively withdrawn or lost rights to appraisal under the DGCL. If any Dissenting Stockholder shall have failed to perfect or shall have effectively withdrawn or lost such right, such holder’s Shares shall thereupon be treated as if they had been converted into and become exchangeable for the right to receive, as of the Effective Time, the Merger Consideration for each such Share, in accordance with Section 3.1(b), without any interest thereon. The Company shall give Parent (i) prompt notice of any written demands for appraisal of any Shares, attempted withdrawals of such demands and any other instruments served pursuant to the DGCL and received by the Company relating to stockholders’ rights of appraisal and (ii) the opportunity to participate in negotiations and proceedings with respect to demands for appraisal under the DGCL. The Company shall not, except with the prior written consent of Parent, voluntarily make any payment with respect to, or settle, or offer or agree to settle, any such demand for payment. The parties hereby agree and acknowledge that in any appraisal proceeding with respect to the Dissenting Shares and to the fullest extent permitted by applicable Law, the fair value of the Dissenting Shares shall be determined in accordance with Section 262 of the DGCL without regard to the Top-Up Option, the Top-Up Shares or the Promissory Note delivered by Merger Sub to the Company in payment for the Top-Up Shares.

Section 3.2 Exchange of Certificates.

(a) Exchange Agent. At or prior to the Effective Time, Parent shall deposit, or shall cause to be deposited, with American Stock Transfer & Trust Company (or another U.S. bank or trust company that shall be appointed by Parent and approved in advance by the Company (such approval not to be unreasonably withheld)) to act as exchange agent hereunder (the “Exchange Agent”), in trust for the benefit of holders of the Shares, immediately available

-10-

funds equal to the aggregate Merger Consideration (collectively, the “Exchange Fund”) and Parent shall instruct the Exchange Agent to timely pay the Merger Consideration in accordance with this Agreement.

(b) Delivery of Merger Consideration.

(i) As soon as reasonably practicable after the Effective Time and in any event not later than the third Business Day following the Effective Time, the Exchange Agent shall mail to each holder of record of Shares whose Shares were converted into the Merger Consideration pursuant to Section 3.1, (i) a letter of transmittal which shall specify that delivery shall be effected, and risk of loss and title to the certificates that immediately prior to the Effective Time represented Shares (“Certificates”) shall pass, only upon delivery of Certificate(s) (or affidavits of loss in lieu of such Certificates) to the Exchange Agent and shall be substantially in such customary form and have such other customary provisions as shall be prescribed by the Exchange Agent and Parent (the “Letter of Transmittal”) and (ii) instructions for use in surrendering Certificate(s) or non-certificated Shares represented by book-entry (“Book-Entry Shares”) in exchange for the Merger Consideration.

(ii) Upon surrender to the Exchange Agent of its Certificate or Certificates (or effective affidavits of loss in lieu thereof) or delivery of an “agent’s message” to the Exchange Agent (or such other evidence, if any, of transfer as the Exchange Agent may reasonably request) in respect of Book-Entry Shares, accompanied by a properly completed Letter of Transmittal, a holder of Company Common Stock will be entitled to receive promptly after the Effective Time the Merger Consideration to be paid in consideration therefor in respect of the Shares represented by its Certificate or Certificates or Book-Entry Shares. No interest will be paid or accrued on any amount payable upon due surrender of Certificates or Book-Entry Shares. Until so surrendered, each such Certificate or Book-Entry Share shall represent after the Effective Time, for all purposes, only the right to receive the Merger Consideration.

(iii) Each of Parent, the Surviving Corporation and the Exchange Agent shall be entitled to deduct and withhold from the Offer Price and the Merger Consideration, as the case may be, otherwise payable pursuant to this Agreement, including amounts payable to holders of Shares, such amounts as are required to be withheld or deducted under the Internal Revenue Code of 1986, as amended (the “Code”), or any provision of U.S. state, local or foreign Law with respect to the making of such payment. To the extent that amounts are so withheld or deducted, such withheld or deducted amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding were made.

(iv) In the event of a transfer of ownership of a Certificate or Book-Entry Shares representing Company Common Stock that is not registered in the stock transfer records of the Company, the proper amount of cash shall be paid in exchange therefor to a Person other than the Person in whose name such Certificate or Book-Entry Shares so surrendered is registered, if such Certificate shall be properly endorsed or otherwise be in proper form for transfer or if such Book-Entry Shares shall be properly transferred, as applicable, and the Person requesting such payment shall pay any transfer or other similar Taxes required by reason of the payment to a Person other than the registered holder of such Certificate or such

-11-

Book-Entry Shares, as applicable, or establish to the satisfaction of Parent that such Tax has been paid or is not applicable.

(c) Closing of Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates or Book-Entry Shares are presented to the Surviving Corporation or Parent for transfer, they shall be cancelled and exchanged for the Merger Consideration in accordance with the procedures set forth in this Article III.

(d) Termination of Exchange Fund. Any portion of the Exchange Fund (including the proceeds of any investments thereof) that remains undistributed to the former holders of Shares for one year after the Effective Time shall be delivered to the Surviving Corporation upon demand, and any former holders of Shares who have not surrendered their Shares in accordance with this Section 3.2 shall thereafter look only to the Surviving Corporation for payment of their claim for the Merger Consideration, without any interest thereon, upon due surrender of their Shares.

(e) No Liability. Notwithstanding anything herein to the contrary, none of the Company, Parent, Merger Sub, the Surviving Corporation, the Exchange Agent or any other Person shall be liable to any former holder of Shares for any amount properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(f) Investment of Exchange Fund. The Exchange Agent shall invest the Exchange Fund as reasonably directed by Parent; provided, however, that any investment of such cash shall in all events be limited to direct short-term obligations of, or short-term obligations fully guaranteed as to principal and interest by, the U.S. government and that no such investment or loss thereon shall affect the amounts payable to holders of Certificates or Book-Entry Shares pursuant to this Article III. Any interest and other income resulting from such investments shall be paid to the Surviving Corporation pursuant to Section 3.2(d).

(g) Lost Certificates. In the case of any Certificate that has 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 required by Parent or the Exchange Agent, the posting by such person of a bond in such sum as Parent may reasonably direct as indemnity against any claim that may be made against Parent, the Surviving Corporation or the Exchange Agent with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration deliverable in respect thereof pursuant to this Agreement.

Section 3.3 Effect of the Merger on Company Stock Options and Company RSUs; ESPP.

(a) As of the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof, each option to acquire Shares granted under the Company’s 2004 Equity Incentive Plan, as amended, and the Dionex Corporation Stock Option Plan (each a

-12-

Company Stock Plan”) or otherwise that is outstanding and unexercised as of immediately prior to the Effective Time (each, a “Company Stock Option”), (i) in the case of the Company Stock Options that are fully vested as of immediately prior to the Effective Time (the “Vested Company Stock Options”), shall terminate and cease to represent a right to acquire Shares, and the holder thereof shall be entitled to receive therefor an amount of cash equal to the product of (x) the number of Shares that were purchasable upon exercise of such Vested Company Stock Option and (y) the Offer Price less the exercise price of such Vested Company Stock Option; and (ii) in the case of the Company Stock Options that are not fully vested as of immediately prior to the Effective Time (the “Unvested Company Stock Options”), shall be assumed by Parent and converted into an award (an “Assumed Award”) representing a right to receive a cash amount equal to the product of (x) the number of Shares underlying the Unvested Company Stock Option that would have become purchasable upon each future vesting date of such Unvested Company Stock Option and (y) the Offer Price less the exercise price of such Unvested Company Stock Option (the “Assumed Award Offer Amount”). The right to receive the Assumed Award Offer Amount in respect of an Assumed Award shall be subject to the vesting terms of the applicable Company Stock Plan and of the award agreements evidencing the corresponding Unvested Company Stock Option as in effect immediately prior to the Effective Time, and such Assumed Award Offer Amount shall be payable as soon as practicable following the applicable vesting dates (but not later than ten (10) Business Days thereafter in any event); provided, however, that (A) if the employment or service of a holder of an unvested Assumed Award who is not an Eligible Employee under the Company’s Change in Control Severance Benefit Plan (the “CIC Plan”) is terminated by Parent or any of its Subsidiaries on or after the Effective Time without Cause (as such term is defined in Section 3.3(a) of the Company Disclosure Letter), all then unvested Assumed Awards shall immediately vest and the holder thereof shall be paid the Assumed Award Offer Amount in respect of such Assumed Awards as soon as reasonably practicable thereafter (and, subject to Section 3.3(c) below, no later than ten (10) Business Days thereafter); or (B) if the employment of a holder of an Assumed Award who is an Eligible Employee under the CIC Plan is terminated by Parent or any of its Subsidiaries under circumstances that constitute a Covered Termination (as defined in the CIC Plan), all then unvested Assumed Awards shall immediately vest and the holder thereof shall be paid the Assumed Award Offer Amount in respect of such Assumed Awards as soon as reasonably practicable after the Covered Termination (and, subject to Section 3.3(c) below, no later than ten (10) Business Days thereafter). For purposes of clarity, with respect to any Assumed Awards held by a member of the Company’s Board of Directors as of the date hereof who does not become a member of the Parent’s Board of Directors as of the Effective Time, as a result of his or her cessation of service as of the Effective Time, the Assumed Award shall immediately vest and such director shall be entitled to be paid the Assumed Award Offer Amount as soon as reasonably practicable thereafter (but no later than ten (10) Business Days thereafter in any event).

(b) As of the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, each award of restricted stock units denominated in Shares granted under a Company Stock Plan or otherwise that is outstanding as of immediately prior to the Effective Time (each a “Company RSU”) shall be assumed by Parent and converted into an award (an “Assumed RSU”) representing a right to receive a cash amount equal to the product of (x) the number of Shares that would have been delivered to the holder on each future vesting date of such Company RSU (or on each future delivery date of such Company RSU, if such

-13-

delivery date is later than the related vesting date) and (y) the Offer Price (the “Assumed RSU Offer Amount”), and such Assumed RSU Offer Amount shall be payable as soon as practicable after the applicable vesting date or delivery date (but not later than ten (10) Business Days thereafter in any event). The right to receive any Assumed RSU Offer Amount in respect of Assumed RSUs shall be subject to the vesting and delivery terms of the applicable Company Stock Plan and of the award agreements evidencing the corresponding Company RSU as in effect immediately prior to the Effective Time; provided, however, (A) that the performance metrics relating to Company RSUs that are subject to the achievement of such performance metrics (such Company RSUs, the “Company Performance RSUs”) shall be deemed to have been achieved at target as of the Effective Time with the number of Company Performance RSUs and the related number of Assumed RSUs to be fixed on the Effective Time at the Target Stock Unit Amount (as set forth in the applicable award agreement) and all other vesting terms of such Assumed RSUs that were originally Company Performance RSUs shall remain the same; (B) that the Assumed RSUs that were originally Company Performance RSUs shall vest, subject to the continuous employment of the applicable employee through each vesting date, as follows: 50% of the Assumed RSUs that were originally Company Performance RSUs shall vest on August 3, 2012; 25% of the Assumed RSUs that were originally Company Performance RSUs shall vest on August 3, 2013; and 25% of the Assumed RSUs that were originally outstanding Company Performance RSUs shall vest on August 3, 2014; and (C) that if the employment or service of a holder of unvested Assumed RSUs (including those that were originally Company Performance RSUs at target, as fixed above) (I) who is not an Eligible Employee under the CIC Plan is terminated by Parent or any of its Subsidiaries on or after the Effective Time without Cause (as such term is defined in Section 3.3(a) of the Company Disclosure Letter), all then unvested Assumed RSUs shall immediately vest and the holder thereof shall be paid the Assumed RSU Offer Amount as soon as practicable thereafter (and, subject to Section 3.3(c) below, no later than ten (10) Business Days thereafter) or (II) who is an Eligible Employee under the CIC Plan, is terminated by Parent or any of its Subsidiaries under circumstances that constitute a Covered Termination (as defined in the CIC Plan), all then unvested Assumed RSUs shall immediately vest and the holder thereof shall be paid the Assumed RSU Offer Amount as soon as reasonably practicable after the Covered Termination (and, subject to Section 3.3(c) below, no later than ten (10) Business Days thereafter). For purposes of clarity, with respect to any Assumed RSUs held by a member of the Company’s Board of Directors as of the date hereof who does not become a member of the Parent’s Board of Directors as of the Effective Time, as a result of his or her cessation of service as of the Effective Time, the Assumed RSU shall immediately vest and such director shall be entitled to be paid the Assumed RSU Offer Amount as soon as reasonably practicable thereafter (but no later than ten (10) Business Days thereafter in any event).

(c) Cash payments made pursuant to Sections 3.3(a) and 3.3(b) above (i) shall be subject to the provisions of Sections 4(f) and 5(g) of the CIC Plan (with respect to the application of Sections 409A and 280G of the Code, respectively) as if such provisions were incorporated into this Agreement, (ii) to the extent payable as a result of a termination of employment, shall be subject to the holder’s execution and non-revocation of a release of claims in favor of the Company, and (iii) shall not serve as an offset to or otherwise reduce the severance benefits that a holder of the right to the cash payments in respect of the Assumed Awards and Assumed RSUs as provided by Sections 3.3(a) and 3.3(b) may be entitled to receive from Parent and its Subsidiaries in connection with the termination of such holder’s employment

-14-

with Parent or any of its Subsidiaries. The Company shall take all necessary actions to cause each Eligible Employee under the CIC Plan to acknowledge the treatment pursuant to this Section 3.3 of Vested Company Stock Options, Unvested Company Stock Options and Company RSUs, in each case, that such Eligible Employee holds as of the Effective Time, and the effectiveness of the modifications to Section 4(d) of the CIC Plan shall be conditioned upon the Eligible Employee’s delivery of such acknowledgment and the restrictive covenant agreement described in Section 4(d) of the CIC Plan.

(d) The Company shall (i) suspend the Company’s 2003 Employee Stock Participation Plan (the “ESPP”) as of the date of this Agreement, (ii) ensure that no new offering periods under the Company ESPP will commence during the period from the date of this Agreement through the Effective Time, (iii) ensure that there will be no increase in the amount of payroll deductions permitted to be made by the participants under the Company ESPP during the current offering period, except those made in accordance with payroll deduction elections that already are in effect as of the date of this Agreement, and (iv) ensure that no individuals shall commence participation in the Company ESPP during the period from the date of this Agreement through the Effective Time. The accumulated contributions of the participants in the current ESPP offering shall be used to purchase Shares within five (5) Business Days prior to the Effective Time, and the participants’ purchase rights under the ongoing offering shall terminate immediately after such purchase. As of the Effective Time, the Company shall terminate the ESPP.

(e) The Parent or any of its Subsidiaries shall be entitled to deduct and withhold from the amounts otherwise payable pursuant to the Vested Stock Options, Assumed Awards and Assumed RSUs with respect to the making of such payment under the Code, or any provision of state, local or foreign Law, and the Parent shall, or shall cause one of its Subsidiaries to, make any required filings with and payments to the applicable Governmental Entity relating to any such deduction or withholding. To the extent that amounts are so deducted and withheld by the Parent or any of its Subsidiaries, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Vested Company Stock Options, Assumed Awards or Assumed RSUs in respect of which such deduction and withholding was made by the Parent or any of its Subsidiaries.

(f) The Board of Directors of the Company (or the appropriate committee thereof) shall adopt such resolutions and take any necessary actions to effectuate the foregoing provisions of this Section 3.3. The Company and Parent agree that, prior to the Offer Closing Date, the Company’s 2004 Equity Incentive Plan shall be amended to preclude any automatic or formulaic grant of options, restricted stock units or other awards thereunder on or after the Offer Closing Date. The Company shall take all necessary action to ensure that after the Effective Time neither Parent nor the Surviving Corporation will be required to deliver Shares or other capital stock of the Company to any Person pursuant to or in settlement of Company Stock Options, Company RSUs or otherwise.

Section 4.5 Reports and Financial Statements.

(a) The Company has filed all registration statements, prospectuses, schedules, forms, documents, statements, certifications and reports (including exhibits and all other information incorporated by reference therein) presently required to be filed prior to the date hereof by them with the SEC since June 30, 2007 (excluding the Schedule 14D-9 and the Proxy Statement, the “Company SEC Documents”).

As of the time of filing with the SEC, none of the Company SEC Documents so filed or that will be filed subsequent to the date of this Agreement contained or will contain, as the case may be, any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except to the extent that the information in such Company SEC Document has been amended or superseded by a later Company SEC Document filed prior to the date hereof. No Subsidiary of the Company is subject to the periodic reporting requirements of the Exchange Act.

(b) The financial statements (including all related notes and schedules) of the Company and its Subsidiaries included in the Company SEC Documents and each Company

-20-

SEC Document filed after the date hereof until the Effective Time, comply (or will comply, as applicable), as of their respective dates of filing with the SEC, in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto, have been prepared (or will have been prepared, as applicable) in accordance with United States generally accepted accounting principles (“GAAP”) (except, in the case of unaudited statements, as permitted by Forms 10-Q or 8-K or other applicable rules of the SEC) applied on a consistent basis during the periods involved (except as may be indicated in the notes thereto) and fairly present (or will fairly present, as applicable) in all material respects the financial position of the Company and its Subsidiaries, as at the respective dates thereof, and the results of their operations and their cash flows for the respective periods then ended (subject, in the case of the unaudited statements, to normal year-end audit adjustments and to any other adjustments described therein, including the notes thereto). The financial books and records of the Company and its Subsidiaries, taken as a whole, are true and correct in all material respects.

(c) Each of the principal executive officer of the Company and the principal financial officer of the Company (or each former principal executive officer of the Company and each former principal financial officer of the Company, as applicable) has made all certifications required by Rule 13a-14 or 15d-14 under the Exchange Act or Sections 302 and 906 of the Sarbanes-Oxley Act and the rules and regulations of the SEC promulgated thereunder with respect to the Company SEC Documents. For purposes of the preceding sentence, “principal executive officer” and “principal financial officer” shall have the meanings given to such terms in the Sarbanes-Oxley Act. Neither the Company nor any of its Subsidiaries has outstanding, or has arranged any outstanding, “extensions of credit” to directors or executive officers within the meaning of Section 402 of the Sarbanes-Oxley Act.

(d) Neither the Company nor any of its Subsidiaries is a party to, or has any commitment to become a party to, any joint venture, off-balance sheet partnership or any similar contract or arrangement (including any contract or arrangement relating to any transaction or relationship between or among the Company and any of its Subsidiaries, on the one hand, and any unconsolidated Affiliate, including any structured finance, special purpose or limited purpose entity or Person, on the other hand, or any “off-balance sheet arrangement” (as defined in Item 303(a) of Regulation S-K of the SEC)), where the result, purpose or intended effect of such contract or arrangement is to avoid disclosure of any material transaction involving, or material liabilities of, the Company or any of its Subsidiaries in the Company’s or such Subsidiary’s published financial statements or other Company SEC Document.

(e) No “material contract” (as such term is defined in Item 601(b)(10) of Regulation S-K of the SEC) filed as an exhibit to the Filed SEC Documents has been amended or modified in any material respect, except for amendments or modifications which have been filed as an exhibit to a subsequently dated Company SEC Document.

(f) The Company maintains a system of internal controls over financial reporting and accounting sufficient in all material respects to provide reasonable assurances regarding the reliability of financial reporting and the preparation of financial statements for external purposes, including to provide reasonable assurance that: (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to

-21-

maintain asset accountability, (iii) access to assets that could have a material effect on the Company’s financial statements is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(h) The Company’s management has completed an assessment of the effectiveness of the Company’s internal controls over financial reporting in compliance with the requirements of Section 404 of Sarbanes Oxley for the fiscal year ended June 30, 2010, and such assessment concluded that such controls were effective.

For purposes of this Agreement, the terms “significant deficiency” and “material weakness” shall have the meanings assigned to them in the Statements of Auditing Standards 60, as in effect on the date hereof.

Since June 30, 2007, no current or former attorney representing the Company or any of its Subsidiaries has reported in writing evidence of a material violation of securities Laws, breach of fiduciary duty or similar violation by the Company or any of its officers, directors, employees or agents to the Board of Directors of the Company or any committee thereof or to any director or executive officer of the Company.

Section 4.9 Employee Benefit Plans.

(a) Section 4.9(a) of the Company Disclosure Letter sets forth a true and complete list of each employee or director benefit plan, arrangement or agreement (other than those employment agreements, offer letters and/or employment contracts that are terminable at-will by the Company or a Subsidiary, as applicable, on no more than one month’s notice or the minimum required notice period under applicable Law, without the payment of severance or other separation pay), except as required by applicable Law, including: (i) any such plan, arrangement or agreement that is an employee welfare benefit plan within the meaning of Section 3(1) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), (ii) an employee pension benefit plan within the meaning of Section 3(2) of ERISA (whether or not such plan is subject to ERISA) or (iii) a bonus, incentive, deferred compensation, vacation, stock purchase, stock option, severance, employment (subject to the exclusion set forth above), change of control, retention, or fringe benefit plan, program or agreement that is sponsored or maintained by the Company or any of its Subsidiaries, or pursuant to which any of their respective ERISA Affiliates has any current or future obligation, to or for the benefit of the employees or directors of the Company and its Subsidiaries (collectively, the “Company Benefit Plans”). Section 4.9(a)(x) of the Company Disclosure Letter identifies the material Company Benefit Plans that are maintained primarily for the benefit of employees of the Company who are regularly employed outside the United States.

(b) The Company has delivered or made available to Parent prior to the date of this Agreement complete and correct copies of each of the Company Benefit Plans and (i) each writing constituting a part of such Company Benefit Plan, including all amendments thereto; (ii) the most recent Annual Reports (Form 5500 Series) and accompanying schedules, if any; (iii) the current summary plan description and any material modifications thereto, if any (in each case, whether or not required to be furnished under ERISA); and (iv) the most recent determination letter from the Internal Revenue Service (“IRS”) (if applicable) for such Company Benefit Plan.

(c) Section 4.9(c) of the Company Disclosure Letter identifies each Company Benefit Plan that is intended to be a “qualified plan” within the meaning of Section 401(a) of the Code (“Qualified Plans”). The IRS has issued a favorable determination letter with respect to each Qualified Plan and the related trust (or the Qualified Plan and related trust are subject to a favorable opinion letter) that has not been revoked, and there are no existing circumstances and no events have occurred that would adversely affect the qualified status of any Qualified Plan or the related trust.

(d) Each of the Company Benefit Plans has been established, operated and administered in all material respects with applicable Laws, including ERISA, the Code and, in each case, the regulations thereunder.

(e) No Company Benefit Plan is subject to Title IV or Section 302 of ERISA or Section 412 or 4971 of the Code. No liability under Title IV of ERISA has been incurred by the Company, its Subsidiaries or any of their ERISA Affiliates that has not been satisfied in full. There does not now exist, nor do any circumstances exist that would reasonably be expected to result in, any Controlled Group Liability that would be a liability of the Company or any of its Subsidiaries following the Effective Time and, without limiting the generality of the foregoing,

-26-

neither the Company nor any of its Subsidiaries, nor any of their ERISA Affiliates, has engaged in any transaction described in Section 4069 or Section 4204 or 4212 of ERISA.

(f) No Company Benefit Plan provides health or life insurance benefits (whether or not insured), with respect to current or former employees or directors of the Company or its Subsidiaries beyond their retirement or other termination of service, other than coverage mandated by applicable Law and, except as may otherwise be required under applicable Law, at the expense of the employee or former employee.

(g) (i) No Company Benefit Plan is a “multiemployer plan” (within the meaning of Section 4001(a)(3) of ERISA) (“Multiemployer Plan”) or a plan that has two or more contributing sponsors at least two of whom are not under common control, within the meaning of Section 4063 of ERISA (a “Multiple Employer Plan”), (ii) none of the Company and its Subsidiaries, nor any of their ERISA Affiliates has, at any time during the last six (6) years, contributed to or been obligated to contribute to any Multiemployer Plan or Multiple Employer Plan and (iii) none of the Company and its Subsidiaries, nor any of their ERISA Affiliates has incurred any Withdrawal Liability that has not been satisfied in full.

(h) Each Company Benefit Plan that is an employee welfare benefit plan under Section 3(1) of ERISA is either (i) funded through an insurance company contract and is not a “welfare benefit fund” within the meaning of Section 419 of the Code or (ii) self-insured and the Company has sufficient reserves to pay run out claims if such Company Benefit Plan is terminated.

(i) All contributions or other amounts payable by the Company or its Subsidiaries as of the date hereof with respect to each Company Benefit Plan in respect of current or prior plan years have been paid or, to the extent not required to be paid, accrued in accordance with GAAP.

(j) Neither the Company nor its Subsidiaries has engaged in a transaction in connection with which the Company or its Subsidiaries would reasonably be expected to be subject to either a material civil penalty assessed pursuant to Section 409 of ERISA or a material Tax imposed pursuant to Section 4975 of the Code. There are no pending, threatened or anticipated claims (other than routine claims for benefits) by, on behalf of or against any of the Company Benefit Plans or any trusts related thereto which would reasonably be expected to result in any material liability to the Company or any of its Subsidiaries, whether insured or uninsured.

(k) Neither the execution and delivery of this Agreement nor the consummation of the transactions contemplated hereby, including the Offer and the Merger, will (either alone or in conjunction with any other event) (i) entitle any employee, officer or director of the Company or any of its Subsidiaries to severance or termination pay, except as may be required by applicable Law, (ii) result in, cause the accelerated vesting, funding or delivery of, or increase the amount or value of, any payment or benefit to any employee, officer or director of the Company or any of its Subsidiaries, except as may be required by applicable Law, or (iii) result in any limitation on the right of the Company or any of its Subsidiaries to amend, merge, terminate or receive a reversion of assets from any Company Benefit Plan or related trust.

-27-

Without limiting the generality of the foregoing, no amount paid or payable (whether in cash, in property, or in the form of benefits) by the Company or any of its Subsidiaries in connection with the transactions contemplated hereby, including the Offer and the Merger (either solely as a result thereof or as a result of such transactions in conjunction with any other event) will be an “excess parachute payment” within the meaning of Section 280G of the Code. No Company Benefit Plan provides for the gross-up or reimbursement of Taxes under Sections 4999 or 409A of the Code, or otherwise.

(l) All Company Stock Options have been granted in compliance with the terms of the applicable Company Benefit Plans, with applicable Law, and with the applicable provisions of the Company Charter and Company Bylaws as in effect at the applicable time, and all such Company Stock Options are accurately disclosed in all material respects as required under applicable Law in (i) the Filed SEC Documents, including the financial statements contained therein or attached thereto (if amended or superseded by a filing with the SEC made prior to the date of this Agreement, as so amended or superseded), and (ii) the Tax Returns of the Company. In addition, the Company has not issued any Company Stock Options or any other similar equity awards pertaining to Shares under any Company Benefit Plan with an exercise price that is less than the “fair market value” of the underlying shares on the date of grant, as determined for financial accounting purposes under GAAP.

(m) All Company Benefit Plans subject to the Laws of any jurisdiction outside of the United States (i) have been established, maintained and administered in all material respects in accordance with all applicable Laws, (ii) if they are required to be registered have been registered and if they are intended to qualify for special tax treatment meet all requirements for such treatment, and (iii) if they are intended to be funded and/or book-reserved are fully funded and/or book reserved, as appropriate, based upon reasonable actuarial assumptions and applicable Law.

(n) Each individual who currently renders services to the Company or any of its Subsidiaries and who is classified by the Company or such Subsidiary, as applicable, as having the status of an independent contractor or other non-employee status for any purpose (including for purposes of taxation and tax reporting and exclusion from participation under the Company Benefit Plans) is properly so characterized, except to the extent that any potential mischaracterization of such an independent contractor or other non-employee by the Company or its Subsidiaries would not reasonably be expected to result in a material liability to the Company or any of its Subsidiaries.

(o) The parties hereto acknowledge that certain payments have been made or are to be made and certain benefits have been granted or are to be granted according to employment, compensation, severance and other Company Benefit Plans or pursuant to the terms of this Agreement, including Sections 3.3, 6.5 and 6.9 (collectively, the “Arrangements”) to certain holders of Shares and other securities of the Company (the “Covered Stockholders”). Payments and grants under the Arrangements (i) are being paid or granted as compensation for past services performed, future services to be performed or future services to be refrained from performing, by the Covered Stockholders (and matters incidental thereto) and (ii) are not calculated based on the number of Shares tendered or to be tendered into the Offer by the applicable Covered Stockholder. The adoption, approval, amendment or modification of each

-28-

Arrangement has been approved as an employment compensation, severance or other employee benefit arrangement solely by independent directors of the Company in accordance with the “safe harbor” requirements of Rule 14d-10(d)(2) under the Exchange Act as a result of the taking, prior to the execution of this Agreement, of all necessary actions by the Board of Directors of the Company, the compensation committee thereof and its independent directors, and, to the extent required, the Board of Directors of the Company, the compensation committee thereof and/or its independent directors, shall take, prior to the initial acceptance for payment by Merger Sub of Company Shares pursuant to the Offer, all other actions necessary to satisfy the “safe harbor” requirements of Rule 14d-10(d)(2) under the Exchange Act with respect to the foregoing Arrangements and any similar arrangement entered into by the Company or any of its Subsidiaries on or, subject to the restrictions contained in this Agreement, after the date hereof.

Section 4.11 Investigations; Litigation. There are no (i) actions, suits or proceedings pending (or, to the knowledge of the Company, threatened) against or affecting the Company or any of its Subsidiaries, or any of their respective properties including Intellectual Property, at law or in equity, or (ii) Orders of any Governmental Entity against the Company or any of its Subsidiaries, in each case that have had or would have, or would reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect.

Section 6.3 No Solicitation.

(a) The Company agrees that none of its, nor any of its Subsidiaries’, respective directors, officers, agents, accountants, financial advisors or attorneys shall (and the Company shall direct and use reasonable best efforts to cause its and its Subsidiaries’ employees who are not officers or directors not to), directly or indirectly: (i) initiate, solicit, knowingly encourage (including by providing information or assistance) or knowingly facilitate any inquiries, proposals or offers with respect to, or the making or completion of, any proposal that constitutes, or would reasonably be expected to lead to, an Alternative Proposal, (ii) provide or cause to be provided any non-public information or data relating to the Company or any of its Subsidiaries in connection with, or have any discussions with, any Person or its Representatives (other than Parent and its Representatives) relating to or in connection with an actual or proposed Alternative Proposal (except to disclose the existence of the provisions of this Section 6.3), (iii) engage in any discussions or negotiations with any Person (other than Parent and its Representatives) concerning an actual or proposed Alternative Proposal, (iv) approve, endorse or recommend, agree to or accept any actual or proposed Alternative Proposal, (v) approve, endorse or recommend, agree to or accept or execute or enter into, any letter of intent, agreement in principle, merger agreement, acquisition agreement, option agreement or other similar agreement related to any actual or proposed Alternative Proposal or (vi) agree to do any of the foregoing. Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in this Section 6.3 by the Company, or any Affiliate or Representative of the Company, shall constitute a breach of this Section 6.3 by the Company.

(b) The Company shall, shall cause each of its Subsidiaries to, and shall direct each of its Representatives to, (i) immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Person or its Representatives (other than the parties hereto) conducted heretofore or that may be ongoing with respect to, or that may reasonably be expected to lead to, any Alternative Proposal, (ii) request the prompt return or destruction of all confidential information previously furnished to any such Person or its Representatives and (iii) take such action as is necessary to enforce any confidentiality or “standstill” provisions or provisions of similar effect to which it is a party or of which it is a beneficiary (in the case of confidentiality or similar provisions, to the extent entered into in connection with or in relation to an Alternative Proposal).

(c) Notwithstanding anything to the contrary in Section 6.3(a) or (b), in the event that, prior to the Offer Closing, the Company receives an unsolicited bona fide written Alternative Proposal that did not result from or arise in connection with a breach of this Section 6.3, and that, in the good faith determination of the Board of Directors of the Company, constitutes or is reasonably likely to result in, a Superior Proposal, it may, subject to compliance with Section 6.3(d), prior to the Offer Closing, take the following actions (but only if and to the extent that the Board of Directors of the Company concludes in good faith, after consultation

-43-

with its outside legal counsel, that the failure to do so would be reasonably likely to cause it to breach or violate its fiduciary duties under applicable law): (i) furnish non-public information with respect to the Company and its Subsidiaries to the Person making such bona fide written Alternative Proposal and its Representatives pursuant to a customary confidentiality agreement containing terms at least as restrictive with respect to such Person as to the use and disclosure of nonpublic, confidential information as the terms contained in the Confidentiality Agreement are with respect to Parent and (ii) participate in discussions or negotiations with, and only with, such Person and its Representatives regarding such bona fide written Alternative Proposal; provided, however, that the Company shall promptly (and in any event within 24 hours) notify Parent that the Board of Directors of the Company has determined to take such actions and the Company shall simultaneously provide or make available to Parent any non-public information concerning the Company or any of its Subsidiaries that is provided to the Person making such bona fide written Alternative Proposal or its Representatives which was not previously provided or made available to Parent. The Company shall not, and shall not cause or permit its Subsidiaries or Representatives to, enter into any confidentiality agreement relating to or in connection with an Alternative Proposal with any Person subsequent to the date of this Agreement except for a customary confidentiality agreement pursuant to clause (i) above of this Section 6.3(c), and neither the Company, nor any of its Subsidiaries or Representatives, has entered into any agreement relating to or in connection with an Alternative Proposal prior to the date hereof, and the Company shall not, and shall not cause or permit its Subsidiaries or Representatives to, enter into any agreement relating to or in connection with an Alternative Proposal following the date hereof, that would prevent the Company from providing any information to Parent as contemplated by this Agreement.

(d) The Company promptly (and in any event within 24 hours) shall advise Parent orally and in writing of (i) any Alternative Proposal or indication or inquiry with respect to or that would reasonably be expected to lead to any Alternative Proposal, (ii) any request for non-public information relating to the Company or its Subsidiaries, other than requests for information not reasonably expected to be related to an Alternative Proposal, and (iii) any inquiry or request for discussion or negotiation regarding an Alternative Proposal, including in each case the identity of the Person making any such Alternative Proposal or indication, inquiry or request and the material terms of any such Alternative Proposal or indication, inquiry or request (including copies of any document or correspondence evidencing such Alternative Proposal or indication, inquiry or request). The Company shall keep Parent reasonably informed of the status (including any material change to the terms thereof) of any such Alternative Proposal or indication, inquiry or request.

(e) The Board of Directors of the Company shall not (i) withdraw, modify or qualify in any manner adverse to Parent or Merger Sub the Recommendation or (ii) make any public statement in connection with the Company Meeting, or in reference to an Alternative Proposal, that is inconsistent with the Recommendation (any action or public statement described in clause (i) or (ii) being referred to as a “Change of Recommendation”), or (iii) authorize, cause or permit the Company or any of its Subsidiaries to enter into any acquisition agreement, merger agreement or similar definitive agreement (other than any customary confidentiality agreement entered into pursuant to clause (i) above of Section 6.3(c)) (an “Alternative Acquisition Agreement”) relating to any Alternative Proposal (A) in each case, unless it concludes in good faith (after consultation with its outside legal advisors) that the failure to do so would be

-44-

reasonably likely to cause it to breach or violate its fiduciary duties under applicable law, and subject to the requirement that (1) the Company shall have complied in all material respects with this Section 6.3, given Parent and Merger Sub prompt written notice advising them of the decision of the Board of Directors of the Company to take such action and, in the event that such decision relates to an Alternative Proposal, such Alternative Proposal shall have been an unsolicited bona fide written Alternative Proposal that did not result from or arise in connection with a breach of this Section 6.3 and that in the good faith determination of the Board of Directors of the Company constitutes a Superior Proposal, and the Company shall have included in such notice the material terms and conditions of the Alternative Proposal, including the identity of the person making any such Alternative Proposal and copies of any document or correspondence evidencing such Alternative Proposal and (2) in the event that such decision relates to an Alternative Proposal: (x) the Company shall have given Parent and Merger Sub three (3) Business Days after delivery of such notice to propose revisions to the terms of this Agreement (or make another proposal) and if Parent and Merger Sub propose to revise the terms of this Agreement (or make another proposal), the Company shall have negotiated, and shall have caused its financial and legal advisors to negotiate, in good faith with Parent and Merger Sub with respect to such proposed revisions or other proposal and (y) the Company Board shall have determined in good faith, after considering the results of such negotiations and giving effect to any proposals, amendments or modifications made or agreed to by Parent and Merger Sub, if any, that such Alternative Proposal constitutes a Superior Proposal, and (B) in the case of any action contemplated by clause (iii) above, unless the Company shall have validly terminated this Agreement in accordance with Section 8.1(h), including the payment of the Termination Fee in accordance with Section 8.2. In the event the Board of Directors of the Company does not make the determination referred to in the preceding clause (A)(2)(y) of this paragraph and thereafter determines to effect a Change of Recommendation pursuant to this Section 6.3(e), the procedures referred to above shall apply anew and shall also apply to any subsequent Change of Recommendation. Following each and every material revision to such Superior Proposal, the Company shall be required to deliver a new written notice to Parent and to again comply with the requirements of this Section 6.3(e) with respect to such new written notice, except that the three (3) Business Day period referred to above shall be reduced to two (2) days (one (1) of which must be a Business Day).

(f) Nothing contained in this Agreement shall prohibit the Company or its Board of Directors from disclosing to its stockholders a position contemplated by Rules 14d-9 and 14e-2(a)(2)-(3) promulgated under the Exchange Act; provided, that such Rules will in no way eliminate or modify the effect that any action pursuant to such Rules would otherwise have under this Agreement; and provided, further, that any such disclosure (other than a “stop, look and listen” or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act) shall be deemed to be a Change of Recommendation unless the Board of Directors of the Company expressly and concurrently reaffirms the Recommendation.

(g) As used in this Agreement, the following terms shall have the following meanings:

(i) “Alternative Transaction” with respect to the Company, shall mean any of the following transactions: (i) any transaction or series of related transactions with one or more third Persons involving: (A) any

The Company will use its reasonable best efforts to have the Proxy Statement cleared by the staff of the SEC as promptly as reasonably practicable after such filing.

The Company will provide to Parent copies of all such filings made and correspondence with the SEC or its staff with respect thereto. If at any time prior to the earlier of the Effective Time and the Termination Date, any information should be discovered by any party hereto which should be set forth in an amendment or supplement to the Proxy Statement so that the Proxy Statement would not include any misstatement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, the party which discovers such information shall promptly notify the other parties hereto and, to the extent required by applicable Law, an appropriate amendment or supplement describing such information shall be promptly filed by the Company with the SEC and disseminated by the Company to the stockholders of the Company.

Section 6.5 Employee Matters.

(a) From and after the Effective Time, the employees of the Company and its Subsidiaries who are employed by the Surviving Corporation as of the Effective Time and who remain employed with the Surviving Corporation thereafter (the “Company Employees”) will be offered participation and coverage under Parent’s and its Subsidiaries’ (excluding, for these purposes, after the Effective Time, the Company and its Subsidiaries) compensation and benefit plans that are substantially similar to the plans generally in effect for similarly situated employees of Parent and its Subsidiaries (the “Parent Benefit Plans”); provided, that continued participation and coverage following the Effective Time under the benefit plans of the Company and its Subsidiaries as in effect immediately prior to the Effective Time shall be deemed to satisfy the obligations under this sentence, it being understood that the Company Employees may commence participating in the comparable Parent Benefit Plans on different dates following the Effective Time with respect to different comparable Parent Benefit Plans.

(b) For all purposes (including purposes of vesting, eligibility to participate and level of benefits) under the employee benefit plans of Parent, the Surviving Corporation and their respective Subsidiaries providing benefits to any Company Employees after the Effective Time (including any such plans that are Company Benefits Plans) (the “New Plans”), each Company Employee shall 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 (i) with respect to benefit accrual under any defined benefit pension plan, (ii) for purposes of any New Plan under which similarly-situated employees of Parent and its Subsidiaries do not receive credit for prior service, (iii) for purposes of any New Plan that is grandfathered or frozen, either with respect to level of benefits or participation, or (iv) to the extent that its application would result in a duplication of benefits with respect to the same period of service. In addition, and without limiting the generality of the foregoing, to the extent legally permissible, (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 replacing comparable coverage under a Company Benefit Plan in which such Company Employee participated immediately before the Effective Time (such plans, collectively, the “Old Plans”), and (ii) for purposes of each New Plan providing medical, dental, pharmaceutical, life insurance and/or vision benefits to any Company Employee, (x) Parent shall, or shall cause the Surviving Corporation to, cause all pre-existing condition exclusions and actively-at-work requirements of such New Plan to be waived for such employee and his or her covered dependents, unless such conditions would not have been waived under the comparable Old Plans of the Company or its Subsidiaries in which such employee participated immediately prior to the Effective Time, and (y) to the extent information is provided to Parent in a form reasonably acceptable to Parent and its plan administrator, Parent shall, or shall cause the Surviving Corporation to, cause any eligible expenses incurred by such employee and his or her covered dependents during the portion of the Old Plan’s plan year 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, maximum out-of-pocket and life-time maximum limitations or 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.

-48-

(c) From and after the Effective Time, Parent shall, or shall cause the Surviving Corporation and its Subsidiaries to, honor all obligations under the Company Benefit Plans in accordance with their terms as in effect immediately before the Effective Time, provided that nothing herein shall prohibit the Surviving Corporation from amending, suspending or terminating any particular Company Benefit Plan to the extent permitted by its terms and applicable Law.

(d) Notwithstanding the foregoing provisions of this Section 6.5, the provisions of Sections 6.5(a), (b) and (c) shall apply only with respect to Company Employees who are covered under Company Benefit Plans that are maintained primarily for the benefit of employees of the Company employed in the United States (including Company Employees regularly employed outside the United States to the extent they participate in such Company Benefit Plans). With respect to Company Employees not described in the preceding sentence, from and after the Effective Time, Parent shall, or shall cause the Surviving Corporation and its Subsidiaries to, comply with all applicable Laws relating to employees and employee benefits matters applicable to such employees.

(e) Prior to the Closing Date, the Board of Directors of the Company (or the appropriate committee thereof) shall adopt resolutions and take such corporate action as is necessary to terminate the Company’s 401(k) plan (the “Company 401(k) Plan”) and to ensure that the account balances of the participants in the Company 401(k) Plan are fully vested upon such plan termination, in each case effective as of the day prior to the Closing Date. Following the Effective Time and as soon as practicable following receipt of a favorable determination letter from the IRS on the termination of the Company 401(k) Plan, the assets thereof shall be distributed to the participants, and Parent shall take the action necessary (including the amendment of Parent’s 401(k) plan (the “Parent 401(k) Plan”)) to permit the Company Employees who are then actively employed to roll over any eligible rollover distributions into Parent’s 401(k) Plan. The Company Employees shall be eligible immediately as of the Effective Time to participate in Parent’s 401(k) Plan.

(f) As soon as reasonably practicable following the date hereof (and in any event prior to the Offer Closing Date), the Company shall, or shall cause its applicable Subsidiary to, take all action necessary to fulfill all consultation and notification requirements, and obtain all approvals from, any unions, works councils or other labor organizations, whether required pursuant to applicable Law or otherwise. Any written or oral communications to the employees, officers or directors of the Company or any of its Subsidiaries pertaining to compensation or benefit matters that relate to or are affected by the transactions contemplated by this Agreement shall be previously approved in writing by Parent, it being agreed that Parent and the Company shall cooperate, including by providing Parent a reasonable period of time to review and approve any such communication, in providing any such mutually agreeable communication.

(g) Without limiting the generality of Section 9.10, the provisions of this Section 6.5 are solely for the benefit of the parties to this Agreement, and no current or former director, officer, employee or any other individual associated therewith shall be regarded for any purpose as a third party beneficiary of this Agreement. Nothing contained in this Agreement shall (i) constitute or be deemed to be an amendment to any Company Benefit Plan or any other

-49-

compensation or benefit plan, program or arrangement of the Company or any of its Subsidiaries for any purpose, (ii) guarantee employment for any period of time, or preclude the ability of Parent or the Surviving Corporation and its Subsidiaries to terminate any employee of the Company or any of its Subsidiaries for any reason, (iii) require Parent or the Surviving Corporation or any of their respective Subsidiaries to continue any Company Benefit Plan, employee benefits plans or arrangements or prevent the amendment, modification or termination thereof, in accordance with the terms thereof and applicable Law.

(b) Subject to the terms and conditions herein provided (including Section 6.6(a)) and without limiting the foregoing, the Company and Parent shall (i) promptly, but in no event later than eight (8) Business Days after the date hereof, file any and all Notification and

Report Forms required under the HSR Act with respect to the Offer and the Merger and the other transactions contemplated hereby and use reasonable best efforts to cause the expiration or termination of any applicable waiting periods under the HSR Act, provided that Parent and Company may agree to modify the timing of the Notification and Report Form filing status of Parent or Company to the extent that they mutually agree that doing so may expedite the HSR Act review, (ii) use reasonable best efforts to cooperate with each other in (x) determining whether any filings are required or advisable, in the reasonable judgment of Parent, to be made with, or consents, permits, authorizations, waivers, clearances, approvals, and expirations or terminations of waiting periods are required to be obtained from, any third parties or other Governmental Entities in connection with the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby and (y) promptly making all such filings and timely obtaining all such consents, permits, authorizations or approvals, (iii) supply to any Governmental Entity as promptly as practicable additional information or documents that may be requested pursuant to any Regulatory Law or by such Governmental Entity, and (iv) use reasonable best efforts to take promptly, or cause to be taken promptly, all other actions and do, or cause to be done, all other things necessary, proper or advisable to consummate and make effective the Offer, the Merger and the other transactions contemplated hereby, including taking all such further action as may be necessary to resolve such objections, if any, as the United States Federal Trade Commission, the Antitrust Division of the United States Department of Justice, or competition authorities of any other jurisdiction for which, in the reasonable judgment of Parent, consents, permits, authorizations, waivers, clearances, approvals and expirations or terminations of waiting periods are required or advisable with respect to the Offer, the Merger and the other transactions contemplated hereby, and to avoid or eliminate each and every impediment under any Law that may be asserted by any Governmental Entity with respect to such transactions so as to enable the Closing to occur as soon as reasonably possible (and to enable the Offer Closing to occur as soon as reasonably possible and in any event no later than the End Date), including (x) negotiating, committing to and effecting, by consent decree, hold separate order or otherwise, the sale, divestiture or disposition of any assets or businesses of Parent or its Subsidiaries or of the Company or its Subsidiaries and (y) otherwise taking or committing to take any actions that after the Closing Date limits the freedom of Parent or its Subsidiaries’ (including the Surviving Corporation’s) freedom of action with respect to, or its ability to retain, one or more of its or its Subsidiaries’ (including the Surviving Corporation’s) businesses, product lines or assets, in each case as may be required in order to avoid the entry of, or to effect the dissolution of, any injunction, temporary restraining order or other Order in any suit or proceeding which would otherwise have the effect of preventing the Closing, materially delaying the Offer Closing or the Closing or delaying the Offer Closing beyond the End Date, provided that the Company will only be required to take or commit to take any such action, or agree to any such condition or restriction, if such action, commitment, agreement, condition or restriction is binding on the Company only in the event the Offer Closing occurs.

(c) Subject to applicable legal limitations and the instructions of any Governmental Entity, the Company and Parent shall keep each other apprised of the status of matters relating to the completion of the Offer, the Merger and the other transactions contemplated thereby, including promptly furnishing the other with copies of notices or other communications received by the Company or Parent, as the case may be, or any of their respective Subsidiaries, from any third party and/or any Governmental Entity with respect to such transactions. The Company and Parent shall permit counsel for the other party reasonable

-51-

opportunity to review in advance, and consider in good faith the views of the other party in connection with, any proposed communication to, including any filings with, any Governmental Entity, and confer in good faith to resolve any disagreement as to their strategy for communicating with any Governmental Entity or third party regarding any Regulatory Law. Each of the Company and Parent agrees not to participate in any substantive meeting or discussion, either in person or by telephone, with any Governmental Entity in connection with the proposed transactions unless it consults with the other party in advance and, to the extent not prohibited by such Governmental Entity, gives the other party the opportunity to attend and participate. Any such disclosures, rights to participate or provisions of information by one party to the other may be made on an outside counsel-only basis to the extent required under applicable Law or as appropriate to protect confidential business information.

(d) Subject to Section 6.6(a), in furtherance and not in limitation of the covenants of the parties contained in this Section 6.6, if any administrative or judicial action or proceeding, including any proceeding by a private party, is instituted (or threatened to be instituted) challenging the Offer, the Merger or any other transaction contemplated by this Agreement as violative of any Regulatory Law, each of the Company and Parent shall cooperate in all respects with each other and shall use their respective reasonable best efforts to contest and resist any such action or proceeding; provided, however, that (subject to the following sentence) the Company shall control the defense and settlement of any stockholder litigation against the Company and/or its directors relating to the transactions contemplated by this Agreement, whether commenced prior to or after the execution and delivery of this Agreement; provided, further, however, that the Company’s counsel shall be reasonably acceptable to Parent, the Company shall not take any significant positions relating any such litigation without consulting Parent in advance, and the Company shall consult with Parent with respect to litigation strategy on a regular basis. The Company agrees that it shall not settle any litigation commenced after the date of this Agreement against the Company or any of its directors or executive officers by any stockholder of the Company relating to this Agreement, the Offer, the Merger, or any other transaction contemplated hereby, without the prior written consent of Parent, such consent not to be unreasonably withheld, conditioned or delayed.

Section 6.9 Indemnification and Insurance.

(a) Parent and Merger Sub agree that all rights to exculpation, indemnification and advancement of expenses for acts or omissions occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, now existing in favor of the current or former directors, officers or employees, as the case may be, of the Company or its Subsidiaries as provided in their respective certificates of incorporation or by-laws or other organization documents or in any agreement shall survive the Effective Time and the Merger and shall continue in full force and effect. Commencing on the Closing Date and continuing for a period of six (6) years from the Effective Time, Parent and the Surviving Corporation shall maintain in effect any and all exculpation, indemnification and advancement of expenses provisions of the Company’s and any of its Subsidiaries’ articles of incorporation and by-laws or

-53-

similar organization documents in effect immediately prior to the Effective Time or in any indemnification agreements of the Company or its Subsidiaries with any of their respective current or former directors, officers or employees in effect as of the date hereof, and shall not amend, repeal or otherwise modify any such provisions in any manner that would adversely affect the rights thereunder of any individuals who at the Effective Time were current or former directors, officers or employees of the Company or any of its Subsidiaries; provided, however, that all rights to indemnification in respect of any Action pending or asserted or any claim made within such period shall continue until the disposition of such Action or resolution of such claim.

(b) From and after the Effective Time, each of Parent and the Surviving Corporation shall jointly and severally, to the fullest extent permitted under applicable Law, indemnify and hold harmless (and advance funds in respect of each of the foregoing) each current and former director or officer of the Company or any of its Subsidiaries (each, together with such Person’s heirs, executors or administrators, an “Indemnified Party”) against any costs or expenses (including advancing reasonable attorneys’ fees and expenses in advance of the final disposition of any claim, suit, proceeding or investigation to each Indemnified Party to the fullest extent permitted by Law), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any actual or threatened claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative (an “Action”), arising out of, relating to or in connection with any action or omission in their capacity as such occurring or alleged to have occurred whether before or after the Effective Time (including acts or omissions in connection with such persons serving as an officer or director or other fiduciary in any entity if such service was at the request or for the benefit of the Company).

(c) Following the Effective Time, the Surviving Corporation shall maintain in effect for six years following the Effective Time directors’ and officers’ liability insurance with a Best rated “A” or better carrier, which insurance shall contain at least the same coverage (including the scope and amount thereof) as, and contain terms and conditions that are equivalent to, the coverage set forth in the current policy of directors’ and officers’ liability insurance maintained as of the date hereof by the Company (the “Current Policy”), and may, at the Surviving Corporation’s option, be in the form of a “tail” policy; provided that in satisfying its obligation under this Section 6.9(c), the Surviving Corporation shall not be obligated to pay more than 250% of the current annual policy premium.

(d) The rights of each Indemnified Party hereunder shall be in addition to, and not in limitation of, any other rights such Indemnified Party may have under the articles of incorporation or by-laws or other organization documents of the Company or any of its Subsidiaries or the Surviving Corporation, any other indemnification agreement or arrangement, the DGCL or otherwise. The provisions of this Section 6.9 shall survive the consummation of the Merger and, notwithstanding any other provision of this Agreement that may be to the contrary, expressly are intended to benefit, and are enforceable by, each of the Indemnified Parties.

(e) In the event Parent, 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 in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in either such case, proper

-54-

provision shall be made so that the successors and assigns of Parent or the Surviving Corporation, as the case may be, shall assume the obligations set forth in this Section 6.9. The agreements and covenants contained herein shall not be deemed to be exclusive of any other rights to which any Indemnified Party is entitled, whether pursuant to Law, contract or otherwise. Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to the Company or any of its Subsidiaries or their respective officers, directors and employees, it being understood and agreed that the indemnification provided for in this Section 6.9 is not prior to, or in substitution for, any such claims under any such policies.

Section 6.10 Notification of Certain Matters. The Company shall give prompt notice to Parent, and Parent shall give prompt notice to the Company, of (i) any notice or other communication received by such party from any Governmental Entity in connection with the Offer, the Merger or the other transactions contemplated hereby or from any Person alleging that the consent of such Person is or may be required in connection with the Offer, the Merger or the other transactions contemplated hereby, if the subject matter of such communication or the failure of such party to obtain such consent would reasonably be expected to be material to the Company, the Surviving Corporation or Parent, (ii) any actions, suits, claims, investigations or proceedings commenced or, to such party’s knowledge, threatened against, relating to or involving or otherwise affecting such party or any of its Subsidiaries which relate to the Offer, the Merger or the other transactions contemplated hereby, (iii) the discovery of any fact or circumstance that, or the occurrence or non-occurrence of any event the occurrence or non-occurrence of which, would cause or result, or would reasonably be expected to cause or result, in any of the conditions to the Offer or the Merger set forth in Annex A or Article VII not being satisfied or satisfaction of those conditions being materially delayed; provided, however, that the delivery of any notice pursuant to this Section 6.10 shall not (x) cure any breach of, or non-compliance with, any other provision of this Agreement or (y) limit the remedies available to the party receiving such notice; and, provided, further, that the failure to give prompt notice hereunder pursuant to clause (iii) shall not constitute a failure of a condition set forth in Annex A or Article VII except to the extent that the underlying fact or circumstance not so notified would constitute such a failure.

Section 6.11 Rule 16b-3. The Company shall take such steps as may be necessary or advisable hereto to cause dispositions of Company equity securities (including derivative securities) pursuant to the transactions contemplated by this Agreement by each individual who is a director or officer of the Company to be exempt under Rule 16b-3 promulgated under the Exchange Act.

Notwithstanding any other provisions of the Offer, and in addition to (and not in limitation of) the rights and obligations of Merger Sub to extend, terminate and/or modify the Offer (subject to the terms and conditions of the Agreement), Merger Sub (i) shall not be required to accept for payment or, subject to any applicable rules and regulations of the SEC (including Rule 14e-1(c) under the Exchange Act (relating to the obligation of Merger Sub to pay for or return tendered Shares promptly after termination or withdrawal of the Offer)), pay for, or may delay the acceptance for payment of or, subject to the restriction referred to above, the payment for, any tendered Shares and (ii) may terminate or amend the Offer as to Shares not then paid for, in the event that at the then-scheduled Expiration Time (as it may be extended pursuant to Section 1.1(e) of the Agreement) or immediately prior to such payment, (A) any waiting period (and extensions thereof) applicable to the transactions contemplated by the Agreement (including the Offer and the Merger) under the HSR Act shall not have expired or been terminated, or any regulatory approval set forth or referenced in Sections 4.4(b)(iii) or 4.4(b)(v)(A), or Sections 5.2(b)(iii), 5.2(b)(iv) or 5.2(b)(v) of the Agreement which in the reasonable judgment of Parent is required or advisable to consummate the transactions contemplated by this Agreement, including the Offer and the Merger, shall not have been obtained or shall not remain in full force and effect (or any statutory waiting period in respect thereof shall not have expired) (all such approvals and the expiration of all such waiting periods, including under the HSR Act, being referred to as the “Requisite Regulatory Approvals”), or any of the Requisite Regulatory Approvals shall have resulted in, or would reasonably be expected to result in, the imposition of a Materially Burdensome Condition, (B) the Minimum Condition shall not have been satisfied or (C) any of the following shall have occurred:

(a) (i) any restraining order, preliminary or permanent injunction or other Order or similar legal restraint or prohibition shall have been issued by any Governmental Entity of competent jurisdiction and shall then be in effect, or (ii) any suit, action or other proceeding shall have been instituted by any Governmental Entity and shall remain pending that would reasonably be expected to result in a restraining order, preliminary or permanent injunction or other Order or similar legal restraint or prohibition, in the case of either clause “(i)” or “(ii)” preventing the consummation of the Offer, the Merger and/or the other transactions contemplated by this Agreement;

(b) (i) any of the representations and warranties of the Company set forth in Sections 4.1 solely as such section relates to the Company, Section 4.2(a) (except to a de minimis extent) Section 4.2(b) (except to a de minimis extent), Section 4.4(a) and Section 4.21 of the Agreement shall not be true and correct in all respects at and as of the date of this Agreement and at and as of immediately prior to the expiration of the Offer as though made at and as of such time (unless any such representation or warranty is made only as of a specific date, in which case as of such specific date) or (ii) any of the other representations and warranties of the Company set forth in this Agreement shall not be true and correct in all respects (without giving effect to any limitation as to “materiality” or “Company Material Adverse Effect” set forth therein) at and as of the date of this Agreement and at and as of immediately prior to the expiration of the Offer as though made at and as of such time (unless any such representation or warranty is made only as of a specific date, in which case as of such specific date), except in the case of the foregoing clause (ii), where the failure to be so true and correct (without giving effect to any limitation as to “materiality” or “Company Material Adverse Effect” set forth therein), individually or in the aggregate, has not had and would not reasonably be expected to have a Company Material Adverse Effect;

(c) the Company shall have failed to perform or comply in all material respects with all of the Company’s covenants and agreements to be performed or complied with by it prior to such time;

(d) since the date of the Agreement, any fact, circumstance, event, change, effect or occurrence shall have occurred that, individually or in the aggregate, has had or would reasonably be expected to have, a Company Material Adverse Effect;

(e) the Company shall have failed to deliver to Parent a certificate signed by the Chief Executive Officer or another senior executive officer of the Company, dated as of the then-scheduled Expiration Time, certifying that the conditions specified in clauses (b) and (c) of this Annex A do not exist; or

(f) the Agreement shall have been terminated in accordance with its terms.

The foregoing conditions are for the sole benefit of Parent and Merger Sub and, subject to the terms and conditions of the Agreement, may be waived by Parent or Merger Sub, in whole or in part at any time and from time to time in the sole discretion of Parent or Merger Sub. The failure or delay by Parent or Merger Sub at any time to exercise any of the foregoing rights shall not operate as a waiver of any such right, and each such right shall be deemed an ongoing right that may be asserted at any time and from time to time.
