2.7 Effect on Capital Stock and Eligible Derivative Securities.

(a) Capital Stock. Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time, by virtue of the First Merger and without any action on the part of Parent, Merger Sub 1, Merger Sub 2, the Company, or the holders of any of the following securities, the following shall occur:

(1) Company Common Stock. Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than shares of Company Common Stock owned by Parent, Merger Sub 1, Merger Sub 2 or the Company, or by any direct or indirect wholly owned Subsidiary of Parent, Merger Sub 1, Merger Sub 2 or the Company, in each case immediately prior to the Effective Time, or Dissenting Shares) shall be canceled and extinguished and automatically converted into the right to receive (i) the Per Share Cash Consideration and (ii) the Per Share Stock Consideration (together with the Per Share Cash Consideration and cash in lieu of fractional shares of Parent Common Stock, the “Merger Consideration”), upon the surrender of the certificate or in the case of Uncertificated Shares, an agent’s message, representing such share of Company Common Stock in the manner provided in Section 2.8 hereof (or in the case of a lost, stolen or destroyed certificate, upon delivery of an affidavit (and bond, if required) in the manner provided in Section 2.10 hereof).

(2) Owned Company Common Stock. Each share of Company Common Stock that is (i) held by the Company as treasury stock or (ii) owned by Parent, Merger Sub 1, Merger Sub 2 or the Company, or by any direct or indirect wholly owned Subsidiary of Parent, Merger Sub 1, Merger Sub 2 or the Company, in each case immediately prior to the Effective Time shall be cancelled and extinguished without any conversion thereof or consideration paid therefor.

(3) Capital Stock of Merger Sub 1. Each share of common stock, par value $.01 per share, of Merger Sub 1 that is issued and outstanding immediately prior to the Effective Time shall be converted into one (1) validly issued, fully paid and nonassessable share of common stock, par value $.01 of the First Merger Surviving Entity. Each certificate evidencing ownership of such shares of common stock of Merger Sub shall thereafter evidence ownership of shares of common stock of the First Merger Surviving Entity.

(4) Effect of Second Merger. Each share of common stock, par value $.01 per share, of the First Merger Surviving Entity that is issued and outstanding immediately prior to the effective time of the Second Merger shall be converted into one (1) validly issued, fully paid and nonassessable share of common stock, par value $.01 of the Surviving Entity. Each certificate evidencing ownership of such shares of common stock of the First Merger Surviving Entity shall thereafter evidence ownership of shares of common stock of the Surviving Entity.

(5) Eligible Derivative Securities. As soon as practicable following the date of this Agreement, each of Parent, Merger Sub 1, Merger Sub 2 and the Company shall take such actions as may be required so that at the Effective Time, each Company Stock Option outstanding immediately prior to the Effective Time that is vested or unvested and has an exercise price below the Per Share Merger Consideration Value (each an “Eligible Company

Stock Option”) shall be entitled to receive, in respect of each share of Company Common Stock then subject to such Eligible Company Stock Option, (i) a fraction of a Merger Share equal to the quotient of (x) (1) the Per Share Merger Consideration Value, less (2) the exercise price per share of Company Common Stock subject to such Eligible Company Stock Option, divided by (y) the Per Share Merger Consideration Value (the “Option Exchange Ratio”) and multiplied by (z) the Per Share Stock Consideration and (ii) an amount of cash equal to the Option Exchange Ratio multiplied by the Per Share Cash Consideration. The number of Merger Shares issuable, and the amount of cash payable, upon conversion of each Eligible Company Stock Option pursuant to this Section 2.7(a)(5) shall be reduced to reflect any amount required to be withheld and deducted by Parent as a result of the conversion of such Company Stock Option pursuant to Section 2.8(f) hereof.

(b) Adjustment to Merger Consideration. The number of shares constituting the Aggregate Stock Consideration and the Per Share Cash Consideration and/or the Per Share Stock Consideration shall be adjusted to reflect fully the appropriate effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Parent Common Stock or Company Capital Stock), reorganization, recapitalization, reclassification or other like change with respect to Parent Common Stock or Company Capital Stock having a record date on or after the date hereof and prior to the Effective Time.

(c) Equity Awards; Company ESPP. Except as provided in Section 2.7(a)(5) hereof, at the Effective Time, (i) each Company Option and each Company Restricted Stock Unit issued by the Company then outstanding under any of the Company Option Plans shall be treated in accordance with the provisions of Section 6.12 hereof and (ii) each purchase right then outstanding under the Company ESPP shall be treated in accordance with the provisions of Section 6.12 hereof.

(d) Repurchase Rights. If any shares of Company Common Stock outstanding immediately prior to the Effective Time are unvested or are subject to a repurchase option, risk of forfeiture or other condition under any applicable restricted stock purchase agreement or other agreement with the Company (“Company Restricted Stock”), then the Merger Consideration issued in exchange for such shares of Company Common Stock will also be unvested and subject to the same repurchase option, risk of forfeiture or other condition.

(e) Fractional Shares. No fraction of a share of Parent Common Stock will be issued by virtue of the First Merger, but in lieu thereof each holder of record of shares of Company Common Stock and each holder of an Eligible Derivative Security who would otherwise be entitled to a fraction of a share of Parent Common Stock (after aggregating all fractional shares of Parent Common Stock that otherwise would be received by such holder of record or such holder of an Eligible Derivative Security) shall, upon surrender of such holder’s Certificate(s) or Uncertificated Shares or upon payment with respect to an Eligible Derivative Security, receive from Parent an amount of cash (rounded to the nearest whole cent), without interest, equal to the product of (i) such fraction, multiplied by (ii) the Closing Average.

2.8 Exchange of Certificates and Payment of Eligible Derivative Securities.

(a) Exchange Agent. Prior to the Effective Time, Parent shall designate its transfer agent Computershare Trust Company, N.A., or another bank or trust company reasonably acceptable to the Company, to act as the exchange agent for the Merger (the “Exchange Agent”) for the purpose of exchanging for the Merger Consideration (i) certificates representing shares of Company Common Stock (the “Certificates”) and (ii) uncertificated shares of Company Common Stock (the “Uncertificated Shares”).

(b) Parent to Provide Merger Consideration. Promptly after the date hereof, Parent shall enter into an agreement with the Exchange Agent, which shall provide that Parent shall make the Merger Consideration available to the Exchange Agent for exchange in accordance with this Article II. In addition, Parent shall make available as necessary from time to time after the Effective Time, as needed, cash in an amount sufficient for payment in lieu of fractional shares pursuant to Section 2.7(e) and any dividends or distributions which holders of shares of Company Common Stock may be entitled pursuant to Section 2.8(d). Any cash and Parent Common Stock deposited with the Exchange Agent shall hereinafter be referred to as the “Exchange Fund.”

(c) Exchange Procedures. Promptly following the Effective Time (and in no event later than seven (7) Business Days after the date upon which the Company’s transfer agent delivers the Company’s certified stockholder records to the Exchange Agent), Parent shall cause the Exchange Agent to mail to each holder of record (as of immediately prior to the Effective Time) of a Certificate or Uncertificated Shares that immediately prior to the Effective Time represented outstanding shares of Company Common Stock: (x) a letter of transmittal in customary form (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent) and (y) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration pursuant to Section 2.7(a), cash in lieu of any fractional shares pursuant to Section 2.7(e) and any dividends or other distributions pursuant to Section 2.8(d). Upon (a) surrender of the Certificates for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and (b) receipt of an “agent’s message” by the Exchange Agent (or such other evidence, if any, of transfer as the Exchange Agent may reasonably request) in the case of a book-entry transfer of Uncertificated Shares, as the case may be, each such holder of Company Common Stock shall be entitled to receive in exchange therefor the Merger Consideration to which such holder is entitled pursuant to Section 2.7(a), payment in lieu of fractional shares which such holder has the right to receive pursuant to Section 2.7(e) and any dividends or distributions payable pursuant to Section 2.8(d), and any Certificates so surrendered shall forthwith be canceled. The Exchange Agent shall accept Certificates upon compliance with such reasonable terms and conditions as the Exchange Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices. No interest shall be paid or accrued for the benefit of holders of the Certificates on the cash amounts payable upon the surrender of such Certificates pursuant to this Section 2.8. Until so surrendered, other than Certificates or Uncertificated Shares representing Dissenting Shares, outstanding Certificates shall be deemed from and after the Effective Time to evidence only the right to receive the Merger Consideration pursuant to Section 2.7(a), cash in lieu of the issuance

of any fractional shares pursuant to Section 2.7(e) and any dividends or distributions payable pursuant to Section 2.8(d). The shares of Parent Common Stock constituting part of such Merger Consideration, at Parent’s option, shall be in uncertificated book-entry form, unless a physical certificate is (i) requested by a holder of shares of Company Common Stock, (ii) requested by the holder of an Eligible Derivative Security or (iii) otherwise required under Applicable Law.

(d) Distributions With Respect to Unexchanged Shares. No dividends or other distributions declared or made after the date hereof with respect to Parent Common Stock with a record date after the Effective Time and no payment in lieu of fractional shares pursuant to Section 2.7(e) will be paid to the holders of any unsurrendered Certificates with respect to the shares of Parent Common Stock represented thereby until the holders of record of such Certificates shall surrender such Certificates. Subject to Applicable Law, following surrender of any such Certificates, the Exchange Agent shall deliver to the record holders thereof, without interest (i) promptly after such surrender, the number of whole shares of Parent Common Stock issued in exchange therefor along with payment in lieu of fractional shares pursuant to Section 2.7(e) and the amount of any such dividends or other distributions with a record date after the Effective Time and theretofore paid with respect to such whole shares of Parent Common Stock and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time and a payment date subsequent to such surrender payable with respect to such whole shares of Parent Common Stock.

(e) Transfers of Ownership. In the event that a transfer of ownership of shares of Company Common Stock is not registered in the stock transfer books or ledger of the Company, or if shares of Parent Common Stock are to be issued in a name other than that in which the Certificates surrendered in exchange therefor are registered, it will be a condition of the issuance thereof that the Certificates so surrendered are properly endorsed and otherwise in proper form for surrender and transfer and the Person requesting such payment has paid to Parent (or any agent designated by Parent) any transfer or other Taxes required by reason of the issuance of shares of Parent Common Stock in any name other than that of the registered holder of the Certificates surrendered, or established to the satisfaction of Parent (or any agent designated by Parent) that such transfer or other Taxes have been paid or are otherwise not payable.

(f) Payment of Eligible Derivative Securities. As promptly as reasonably practicable after the Closing Date (but in no event later than ten (10) days after the Closing Date), the Company shall provide to Parent a list of Eligible Derivative Securities and Parent shall (or Parent shall cause the Surviving Entity to) pay each holder of an Eligible Derivative Security the Merger Consideration payable with respect to such Eligible Derivative Securities (including providing instructions to Parent’s transfer agent to issue Merger Shares to each holder of an Eligible Derivative Security). Such payment shall be made under Parent’s (or the Surviving Entity’s) payroll system and in accordance with standard payroll practices (including withholding for applicable Taxes). Subject to Applicable Law, following receipt of instructions from Parent, the Exchange Agent shall deliver to the holders of such Eligible Derivative Securities, without interest (i) promptly after such receipt, the number of whole shares of Parent Common Stock issued in exchange therefor along with payment in lieu of fractional shares pursuant to Section 2.7(e) and the amount of any dividends or other distributions, if any, with a

record date after the Effective Time and theretofore paid with respect to such whole shares of Parent Common Stock and (ii) at the appropriate payment date, the amount of dividends or other distributions, if any, with a record date after the Effective Time and a payment date subsequent to the receipt of such instruction payable with respect to such whole shares of Parent Common Stock.

(g) Required Withholding. Each of the Exchange Agent, Parent and the Surviving Entity shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of shares of Company Common Stock or Eligible Derivative Securities such amounts as may be required to be deducted or withheld therefrom under United States federal or state, local or foreign law. To the extent that such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

(h) No Liability. Notwithstanding anything to the contrary set forth in this Agreement, none of the Exchange Agent, Parent, the Surviving Entity or any other party hereto shall be liable to a holder of shares of Parent Common Stock or Company Common Stock or Eligible Derivative Securities for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar Legal Requirements.

(i) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of Certificates or Uncertificated Shares twelve (12) months after the Effective Time due to the holder’s failure to comply with this Section 2.8 shall, at the request of Parent, be delivered to Parent or otherwise according to the instruction of Parent, and any holders of the applicable Certificates or Uncertificated Shares (including holders of Certificates who have not surrendered such Certificates in compliance with this Section 2.8) shall after such delivery to Parent look only to Parent for the Merger Consideration pursuant to Section 2.7(a), cash in lieu of any fractional shares pursuant to Section 2.7(e) and any dividends or other distributions pursuant to Section 2.8(d) with respect to the shares of Company Common Stock formerly represented thereby.

2.9 No Further Ownership Rights in Company Common Stock. From and after the Effective Time, all shares of Company Common Stock shall no longer be outstanding and shall automatically be cancelled, retired and cease to exist, and each holder of a Certificate or Uncertificated Shares theretofore representing any shares of Company Common Stock (other than Dissenting Shares) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration pursuant to Section 2.7(a), cash in lieu of any fractional shares pursuant to Section 2.7(e) and any dividends or other distributions pursuant to Section 2.8(d) therefor upon the surrender thereof in accordance with the provisions of Section 2.8 hereof. All cash delivered and shares of Parent Common Stock issued upon the surrender for exchange of shares of Company Common Stock in accordance with the terms hereof (including any cash paid in respect thereof pursuant to Section 2.7(e) and Section 2.8(d)) shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Company Common Stock, and there shall be no further registration of transfers on the records of the Surviving Entity of shares of Company Common Stock which were outstanding immediately prior to the Effective Time.

If, after the Effective Time, Certificates or Uncertificated Shares are presented to the Surviving Entity for any reason, they shall be canceled and exchanged as provided in this Article II.

2.10 Lost, Stolen or Destroyed Certificates. In the event that any Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, the Merger Consideration pursuant to Section 2.7(a), cash for fractional shares pursuant to Section 2.7 and any dividends or distributions payable pursuant to Section 2.8(d); provided, however, that Parent may, in its discretion and as a condition precedent to the issuance thereof, require the owners of such lost, stolen or destroyed Certificates to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Parent, the Surviving Entity or the Exchange Agent with respect to the Certificates alleged to have been lost, stolen or destroyed.

2.11 Tax Consequences. It is intended by the parties hereto that the Merger shall constitute a reorganization within the meaning of Section 368(a) of the Code. The parties hereto adopt this Agreement as a plan of reorganization within the meaning of Treasury Regulations Sections 1.368-1(c), 1.368-2(g) and 1.368-3(a).

2.12 Appraisal Rights.

(a) Notwithstanding anything in this Agreement to the contrary, any shares (the “Dissenting Shares”) of the Company Common Stock that are issued and outstanding immediately prior to the Effective Time and that are held by Company Stockholders who, in accordance with Section 262 of the DGCL (the “Appraisal Rights Provisions”), (i) have not voted in favor of adopting this Agreement, (ii) shall have demanded properly in writing appraisal for such shares, (iii) have otherwise complied in all respects with the Appraisal Rights Provisions, and (iv) have not effectively withdrawn, lost, or failed to perfect their rights to appraisal (the “Dissenting Stockholders”), will not be converted into the right to receive the Merger Consideration in accordance with Section 2.7(a), but at the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, shall be cancelled, retired and cease to exist and shall represent the right to receive only those rights provided under the Appraisal Rights Provisions; provided, however, that all shares of Company Common Stock held by Company Stockholders who shall have failed to perfect or who effectively shall have withdrawn or lost their rights to appraisal of such shares of Company Common Stock under the Appraisal Rights Provisions shall thereupon be deemed to have been cancelled and to have been converted, as of the Effective Time, into the right to receive, without any interest thereon, the Merger Consideration in accordance with Section 2.7(a), cash in lieu of any fractional shares pursuant to Section 2.7(e) and any dividends or other distributions pursuant to Section 2.8(d).

(b) The Company shall give Parent, Merger Sub 1 and Merger Sub 2 prompt notice of any demands received by the Company for the exercise of appraisal rights with respect to shares of Company Common Stock and Parent shall have the right to participate in all negotiations and proceedings with respect to such demands. The Company shall not, except with the prior written consent of Parent, which consent shall not be unreasonably withheld, (i) make any payment with respect to any demands for appraisal for Dissenting Shares, (ii) settle or offer

to settle, any such demands, (iii) waive any failure to timely deliver a written demand for appraisal in accordance with Delaware Law, or (iv) agree to do any of the foregoing.

ARTICLE III

REPRESENTATIONS AND WARRANTIES OF THE COMPANY

Except (a) as set forth in the section of the disclosure schedule delivered by the Company to Parent on the date of this Agreement (the “Company Disclosure Schedule”) that specifically relates to such Section or in another section of the Company Disclosure Schedule to the extent it is reasonably apparent from the text of such disclosure that such disclosure is applicable to such other Section, or (b) as set forth in the Company SEC Reports filed after January 1, 2008 and prior to the date of this Agreement (excluding all disclosures in any “risk factors” section and any other prospective or forward-looking information), the Company hereby represents and warrants to Parent, Merger Sub 1 and Merger Sub 2 as follows:

3.1 Organization and Standing. The Company is a corporation duly organized, validly existing and in good standing under Delaware Law. Each of the Company’s Subsidiaries is duly organized, validly existing and in good standing under the laws of the jurisdiction of its respective organization (to the extent the “good standing” concept is applicable in the case of any jurisdiction outside the United States).

In addition to the obligations of Parent

set forth in Sections 6.1(a) and (c) hereof, Parent shall promptly after any of Parent’s directors, executive officers or financial advisors first obtain knowledge of the receipt thereof, and in all cases within one (1) Business Day thereafter, advise the Company orally and in writing of (i) any Acquisition Proposal or (ii) any request for information or inquiry that Parent determines in good faith is reasonably likely to lead to an Acquisition Proposal.

(f) The Company shall keep Parent, or Parent shall keep the Company, as applicable, promptly and reasonably informed of the status and material terms and conditions (including all material amendments or proposed material amendments) of any such Acquisition Proposal, request or inquiry.

6.2 Company Board Recommendation.

(a) Subject to the terms of Section 6.2(b) hereof, the Company Board shall recommend that the Company Stockholders adopt this Agreement in accordance with the applicable provisions of Delaware Law (the “Company Board Recommendation”). Subject to Section 6.2(b), the Proxy Statement shall contain the Company Board Recommendation.

(b) Subject to the terms of this Section 6.2(b), neither the Company Board nor any committee thereof shall withhold, withdraw, amend or modify in a manner adverse to Parent, or publicly propose to withhold, withdraw, amend or modify in a manner adverse to Parent, the Company Board Recommendation (a “Company Board Recommendation Change”); provided, however, that (a) notwithstanding the foregoing, at any time prior to the receipt of the Company Stockholder Approval the Company Board may effect a Company Board Recommendation Change, whether in response to a Superior Proposal or for any other reason deemed appropriate by the Company Board, if the Company Board determines in good faith, after consulting with its outside legal counsel, that the failure to take such action is reasonably likely to result in a breach of its fiduciary duties under applicable Legal Requirements; and (b) the Company Board may not effect a Company Board Recommendation Change unless: (A) the Company Board shall have first provided prior written notice to Parent that it is prepared to effect a Company Board Recommendation Change (which notice shall not, in and of itself, constitute a Company Board Recommendation Change), and (B) Parent does not deliver to the Company, within three (3) days after the receipt of such notice, a proposal that would, in the good faith judgment of the Company Board (after consulting with a financial advisor of national reputation and outside legal counsel), (x) cause the offer previously constituting a Superior Proposal to no longer constitute a Superior Proposal or (y) otherwise render the failure to effect a Company Board Recommendation Change no longer reasonably likely to result in a breach of the Company Board’s fiduciary duties under applicable Legal Requirements. The Company agrees that, during the three (3) day period prior to the Company Board effecting a Company Board Recommendation Change, the Company and its officers, directors and representatives shall negotiate in good faith with Parent and its officers, directors, and representatives regarding any revisions to the terms of the transaction contemplated by this Agreement proposed by Parent.

(c) Nothing contained in this Section 6.2 or elsewhere in this Agreement shall prohibit the Company from (i) taking and disclosing to its stockholders a position contemplated by Rule 14d-9 and Rule 14e-2(a) promulgated under the Exchange Act or (ii) making any disclosure to its stockholders if, in the good faith judgment of the Company (after consulting

with outside legal counsel), such disclosure is necessary in order for the Company to comply with its disclosure obligations under applicable Legal Requirements; provided, however, that any “stop, look and listen” communication of the type contemplated by Rule 14d-9(f) and any other disclosure made pursuant to this Section 6.2(c) that is limited to describing the existence and terms of an Acquisition Proposal shall not be deemed to be a Company Board Recommendation Change so long as the Company Board reaffirms in such disclosure the Company Board Recommendation.

(d) For the avoidance of doubt, a Company Board Recommendation Change shall not change the corporate approval of this Agreement under Section 251(b) of the DGCL, or any corporate approval of the Company Board of this Agreement in any respect that would have the effect of causing any state (including Delaware) corporate takeover statute or other similar statute to be applicable to the transactions contemplated hereby, including the Merger.

6.3 Company Stockholders’ Meeting. The Company shall establish a record date for, call, give notice of, convene and hold a meeting of the Company Stockholders (the “Company Stockholders’ Meeting”) as promptly as practicable following the date hereof for the purpose of voting upon the adoption of this Agreement in accordance with Delaware Law. Nothing herein shall prevent the Company from postponing or adjourning the Company Stockholders’ Meeting if there are insufficient shares of the Company Common Stock necessary to conduct business at the Company Stockholders’ Meeting. Unless this Agreement is earlier terminated pursuant to Article VIII hereof, the Company shall establish a record date for, call, give notice of, convene and hold the Company Stockholders’ Meeting for the purpose of voting upon the adoption of this Agreement in accordance with Delaware Law, whether or not (x) the Company Board shall have effected a Company Board Recommendation Change or (y) any Acquisition Proposal shall have been publicly proposed or announced or otherwise submitted to Company or any of its advisors. In connection with the Company Stockholders’ Meeting, Company shall (i) mail the Proxy Statement and all other proxy materials for such meeting to its stockholders as promptly as practicable after the Form S-4 is declared effective under the Securities Act, (ii) use all commercially reasonable efforts to obtain the Company Stockholder Approval, and (iii) otherwise comply with all Legal Requirements applicable to such meeting.

6.4 Form S-4 and Proxy Statement.

(a) As promptly as practicable after the execution of this Agreement, the Company and Parent shall prepare, and Parent shall file with the SEC a Registration Statement on Form S-4 in connection with the issuance of shares of Parent Common Stock in the Merger (as may be further amended or supplemented from time to time, the “Form S-4”), in which the Proxy Statement will be included. Each of the Company and Parent shall use its commercially reasonable efforts to have the Form S-4 declared effective under the Securities Act as promptly as practicable after such filing and to keep the Form S-4 effective as long as is necessary to consummate the Merger. The Company and Parent shall use their respective commercially reasonable efforts to cause the Proxy Statement to be mailed to the Company Stockholders as promptly as practicable after the Form S-4 is declared effective under the Securities Act. Parent shall also take any action required to be taken under any applicable state securities laws in connection with the issuance of shares of Parent Common Stock in the Merger.

(b) Each of the Company and Parent shall provide the other party and their respective counsel with (i) any comments or other communications, whether written or oral, that such party or its counsel may receive from time to time from the SEC or its staff with respect to the Proxy Statement or the Form S-4, as applicable, promptly after receipt of those comments or other communications and (ii) a reasonable opportunity to participate in the response to those comments.

(c) No amendment or supplement to the Proxy Statement or the Form S-4 will be made by Parent or the Company without the approval of the other parties hereto, which approval shall not be unreasonably withheld or delayed. Each of the Company and Parent will advise the other party promptly after it receives notice thereof, of the time when the Form S-4 has become effective or any supplement or amendment has been filed, the issuance of any stop order, the suspension of the qualification of Parent Common Stock issuable in connection with the Merger for offering or sale in any jurisdiction, or any request by the SEC for amendment of the Proxy Statement or the Form S-4. If, at any time prior to the Effective Time, Parent or the Company discovers any information relating to any party, or any of their respective Affiliates, officers or directors, that should be set forth in an amendment or supplement to the Proxy Statement or the Form S-4, so that none of those documents would include any misstatement of a material fact or omit to state any material fact necessary to make the statements in any such document, in light of the circumstances under which they were made, not misleading, the party that discovers that information shall promptly notify the other party and an appropriate amendment or supplement describing that information shall be promptly filed with the SEC and, to the extent required by law or regulation, disseminated to the stockholders of Parent and the Company.

6.5 Reasonable Best Efforts to Complete.

(a) Upon the terms and subject to the conditions set forth in this Agreement, each of Parent, Merger Sub 1, Merger Sub 2 and the Company shall use their reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other party or parties hereto in doing, all things reasonably necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated by this Agreement, including using reasonable best efforts to: (i) cause the conditions to the Merger set forth in Article VII hereof to be satisfied or fulfilled, including by filing as promptly as practicable after the date hereof with the SEC all annual, quarterly and current reports required to be filed by the Company under the Exchange Act for any and all periods ending prior to the Effective Time, which such annual, quarterly and current reports shall comply as to form with the rules and regulations of the SEC applicable to such reports; (ii) obtain all necessary or appropriate consents, waivers and approvals under any Contracts to which the Company or any of its Subsidiaries is a party in connection with this Agreement and the consummation of the transactions contemplated hereby so as to maintain and preserve the benefits under such Contracts following the consummation of the transactions contemplated by this Agreement; (iii) obtain all necessary actions or non-actions, waivers, consents, approvals, Orders and authorizations from Governmental Entities, the expiration or termination of any applicable waiting periods, making all necessary registrations, declarations and filings (including registrations, declarations and filings with Governmental Entities, if any)

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

(b) Without limiting the generality of the foregoing provisions of Section 6.5(a) hereof and to the extent required by applicable Legal Requirements, as soon as may be reasonably practicable following the execution and delivery of this Agreement, each of Parent and/or the Company shall file applicable pre-merger or post-merger notification filings, forms and submissions with any foreign Governmental Entity that may be required by the merger notification or control laws and regulations of any applicable foreign jurisdiction; provided, however, that the conditions to the parties’ respective obligations to consummate the Merger shall be limited to those conditions specified in Article VII. Each of Parent and the Company shall promptly (i) cooperate and coordinate with the other in the making of such filings, (ii) supply the other with any information that may be required in order to effectuate such filings and (iii) supply any additional information that reasonably may be required or requested by the competition or merger control authorities of any other applicable jurisdiction. Each of Parent and the Company shall also cooperate with one another in determining whether any other Consent of or with a Governmental Entity is required in connection with the consummation of the transactions contemplated by this Agreement and in seeking or making any such Consent; provided, however, that the conditions to the parties’ respective obligations to consummate the Merger shall be limited to those conditions specified in Article VII. Each party hereto shall promptly inform the other party or parties hereto, as the case may be, of any written communication from any Governmental Entity regarding the Merger. If any party hereto or Affiliate thereof receives a written request for additional information or documentary material from any such Governmental Entity with respect to the Merger, then such party shall use commercially reasonable efforts to make, or cause to be made, as soon as reasonably practicable and after consultation with the other party, an appropriate response in compliance with such request. In respect of any meeting with a Governmental Entity for the foregoing purpose, to the extent permitted by the applicable Governmental Entity, each party shall give the other the opportunity to attend and participate in any such meeting. Notwithstanding any provision herein to the contrary, neither Parent nor the Company shall, nor shall they permit their respective Affiliates to (x) extend any waiting period, second request period or other period under any merger notification or control laws or enter into any agreement (including any timing or standstill letter), consent decree, hold separate order or other similar arrangement with any Governmental Entity in connection with any merger notification or control laws without the prior written consent of the other party or (y) acquire or agree to acquire any assets, business, Person or division thereof if any such acquisition or agreement could have the effect of delaying the Effective Time or preventing the Merger or the other transactions contemplated by this Agreement (including with reference to any merger notification or control laws).

(c) Without limiting the generality of the foregoing provisions of Section 6.5(a) hereof, in the event that any state anti-takeover or other similar statute or regulation is or becomes applicable to this Agreement or any of the transactions contemplated by this Agreement, the Company, at the direction of the Company Board, shall use commercially reasonable efforts to ensure that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms and subject to the conditions set forth in this Agreement, and otherwise to minimize the effect of such statute or regulation on this Agreement and the transactions contemplated hereby.

(d) Notwithstanding any provision herein to the contrary, Parent shall negotiate, litigate and take any other action necessary to eliminate any concerns of any Governmental Entity and to avoid the entry (or to effect the dissolution) of any injunction, temporary restraining Order or other Order in any Legal Proceeding by any Governmental Entity in connection with any merger notification or control laws related to the Merger and the other transactions contemplated by this Agreement that has had or could have the effect of delaying the Effective Time beyond the date set forth in Section 8.1(b) or preventing the Merger or the other transactions contemplated by this Agreement, which negotiation, litigation or taking of other action may include: (i) offering to commit and effect (and, if such offer is accepted, committing to and effecting), by agreement, consent decree, hold separate order or otherwise, the sale, divestiture or disposition of any assets or businesses of Parent and any of its Affiliates and, to be effective as of or after the Effective Time, the Surviving Entity and its Affiliates; (ii) otherwise offering to take or offering to commit to take any action (and, if such offer is accepted, taking or committing to take such action) that limits Parent’s or the Surviving Entity’s freedom of action with respect to, or Parent’s or the Surviving Entity’s ability to retain, any of the businesses, services or assets of Parent or the Surviving Entity or their respective Affiliates; or (iii) accepting an offer of any such Governmental Entity with respect to any of the foregoing. The parties acknowledge and agree that the provisions of this Section 6.5(d) require specific results and shall not be satisfied by or with the mere exercise of efforts by Parent (including even reasonable best efforts by Parent) to achieve those results.

(e) In connection with the Company self-disclosure and “narrative account” described in clause (v) of Section 5.1, Parent will (and will use its best efforts to cause its export control counsel to) respond promptly to any Company requests for advice, input and/or approval, and will otherwise use reasonable efforts to facilitate the Company’s timely preparation and filing of such self-disclosure and narrative account.

6.6 Company Rights Plan. At all times during the period commencing with the execution and delivery of this Agreement and continuing until the Effective Time or the termination of this Agreement, the Company and the Company Board shall not amend or modify, or take any other action with regard to the Company Rights Plan in any manner, or take any other action so as to render the Company Rights Plan applicable to Parent, Merger Sub 1, Merger Sub 2 or any of their Affiliates.

6.7 Access. At all times during the period commencing with the execution and delivery of this Agreement and continuing until the earlier to occur of the termination of this Agreement pursuant to Article VIII hereof and the Effective Time, each party shall afford the other party and the other party’s accountants, legal counsel and other representatives reasonable access during normal business hours, upon reasonable notice, to the properties, books and records and personnel of such party to enable the other party to obtain all information concerning the business, properties, facilities, results of operations and personnel of such party, as the other party may reasonably request; provided, however, that (a) no information or Knowledge obtained by the other party in any investigation conducted pursuant to this Section 6.7 shall affect or be deemed to modify any representation or warranty of such party set forth herein or the conditions to the obligations of the other party to consummate the transactions contemplated by this Agreement, or the remedies available to the parties hereunder; and (b) the terms and conditions of the Confidentiality Agreement shall apply to any information provided pursuant to this

Section 6.7. Neither party nor any of its Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would contravene any Legal Requirement or Contract entered into prior to the date of this Agreement, would reasonably be expected to violate or result in a loss or impairment of any attorney-client or work product privilege or would violate or prejudice the rights of third parties. The parties will use commercially reasonable efforts to make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.

6.8 Notification. At all times during the period commencing with the execution and delivery of this Agreement and continuing until the earlier to occur of the termination of this Agreement pursuant to Article VIII hereof and the Effective Time:

(a) the Company shall give prompt notice to Parent upon any director or executive officer or the Company becoming aware that any representation or warranty made by it in this Agreement has become untrue or inaccurate, or of any failure of the Company to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement, in each case such that the conditions to the obligation of Parent, Merger Sub 1 and Merger Sub 2 to consummate the Merger set forth in Section 7.3(a) or Section 7.3(b) would not be satisfied;

(c) Parent shall give prompt notice to the Company upon any director or executive officer of Parent becoming aware that any representation or warranty made by it, Merger Sub 1 or Merger Sub 2 in this Agreement has become untrue or inaccurate, or of any failure of Parent, Merger Sub 1 or Merger Sub 2 to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement, in each case such that the conditions to the obligation of the Company to consummate the Merger set forth in Section 7.2(a) or Section 7.2(b) would not be satisfied; and

(d) The Company will keep Parent informed about the status of the matters identified in Section 3.11(c) of the Company Disclosure Schedule, including notifying Parent promptly of any material developments and consulting with Parent in advance of taking any material action in respect of those matters, and will consider in good faith any input of Parent in respect of Company’s handling of such matters.

The Company shall promptly advise Parent, and Parent shall promptly advise the Company, as applicable, orally and in writing of any litigation commenced after the date hereof against the Company or any of its directors by any Company Stockholders (on their own behalf or on behalf of the Company) or against Parent or any of its directors by any Parent Stockholders (on their own behalf or on behalf of Parent), as applicable, relating to the Merger and shall keep Parent and the Company, as applicable, reasonably informed regarding any such litigation.

6.10 Confidentiality. Parent, Merger Sub 1, Merger Sub 2 and the Company hereby acknowledge that Parent and the Company have previously executed a Confidentiality Agreement, dated September 18, 2007 (as amended, the “Confidentiality Agreement”), which will continue in full force and effect in accordance with its terms.

6.11 Public Disclosure. (a) Except with respect to any action taken pursuant to Section 6.2, Parent, Merger Sub 1, Merger Sub 2 and the Company shall consult with each other, and to the extent practicable, agree, before issuing any press release or otherwise making any public statement with respect to this Agreement and the transactions contemplated hereby, and shall not issue any such press release or make any such public statement prior to such consultation, except as may be required by applicable Legal Requirement or any listing agreement with a national securities exchange, in which case commercially reasonable efforts to consult with the other party hereto shall be made prior to any such release or public statement.
