Section 3.1 Conversion of Shares.

(a) At the Effective Time except as otherwise provided in Section 3.4(d), each share of the Company’s common stock, $.01 par value (the “Common Stock”), issued and outstanding immediately prior to the Effective Time (other than shares of Common Stock to be cancelled pursuant to Section 3.1(c) and Dissenting Shares) shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into the right to receive $66.50 in cash (the “Merger Consideration”) without any interest thereon.

(b) Each share of common stock, $.01 par value, of Sub issued and outstanding immediately prior to the Effective Time shall, at the Effective Time, by virtue of the Merger and without any action on the part of Parent, be converted into one fully paid and nonassessable share of the common stock, $.01 par value, of the Surviving Corporation.

(c) All shares of Common Stock that are owned by the Company as treasury stock and any shares of Common Stock owned by Parent, Sub or any other direct or indirect wholly-owned Subsidiary of Parent shall, at the Effective Time, be cancelled and shall cease to exist, and no consideration shall be delivered in exchange therefor.

(d) At the Effective Time, each share of Common Stock converted into the right to receive the Merger Consideration pursuant to Section 3.1(a) shall be automatically cancelled and shall cease to exist, and the holders immediately prior to the Effective Time of shares of outstanding Common Stock not represented by certificates (“Book-Entry Shares”) and the holders of certificates that, immediately prior to the Effective Time, represented shares of outstanding Common Stock (the “Certificates”) shall cease to have any rights with respect to such shares of Common Stock other than the right to receive, upon surrender of such Book-Entry Shares or Certificates in accordance with Section 3.2, the Merger Consideration, without any interest thereon, for each such share of Common Stock held by them.

(e) If at any time between the date of this Agreement and the Effective Time any change in the number of outstanding shares of Common Stock shall occur as a result of a reclassification, recapitalization, stock split (including a reverse stock split), or combination, exchange or readjustment of shares, or any stock dividend or stock distribution with a record date during such period, the amount of the Merger Consideration as provided in Section 3.1(a) shall be equitably adjusted to reflect such change.

Section 3.2 Exchange of Certificates and Book-Entry Shares.

(a) At or prior to the Closing, Parent shall deliver, in trust, to Mellon Investor Services L.L.C. (the “Paying Agent”), for the benefit of the holders of shares of Common Stock at the Effective Time, sufficient funds for timely payment of the aggregate Merger Consideration (such cash being hereinafter referred to as the “Consideration Fund”) to be paid pursuant to this Section 3.2 in respect of Certificates and Book-Entry Shares, assuming no Dissenting Shares. In the event the Consideration Fund shall be insufficient to pay the aggregate Merger Consideration contemplated by Section 3.1, Parent shall promptly deliver, or cause to be delivered, additional funds to the Paying Agent in an amount that is equal to the deficiency required to make such payments.

(b) Promptly after the Effective Time, Parent shall cause the Paying Agent to mail to each holder of record of Certificates or Book-Entry Shares whose shares were converted into the right to receive Merger Consideration pursuant to Section 3.1 (i) a letter of transmittal that shall specify that delivery of such Certificates or Book-Entry Shares shall be deemed to have occurred, and risk of loss and title to the Certificates or Book-Entry Shares, as applicable, shall pass, only upon proper delivery of the Certificates (or affidavits of loss in lieu thereof) or Book-Entry Shares to the Paying Agent and (ii) instructions for use in effecting the surrender of the Certificates or Book-Entry Shares in exchange for payment of the Merger

Consideration, the form and substance of which letter of transmittal and instructions shall be substantially as reasonably agreed to by the Company and Parent and prepared prior to the Closing. Upon surrender of a Book-Entry Share or a Certificate for cancellation to the Paying Agent together with such letter of transmittal, duly executed and completed in accordance with the instructions thereto, and with such other documents as may be required pursuant to such instructions, the holder of such Book-Entry Share or Certificate shall be entitled to receive in exchange therefor, subject to any required withholding of Taxes, the Merger Consideration pursuant to the provisions of this Article III, and the Book-Entry Share or Certificate so surrendered shall forthwith be cancelled. No interest will be paid or accrued on the Merger Consideration payable to holders of Book-Entry Shares or Certificates. If any Merger Consideration is to be paid to a Person other than a Person in whose name the Book-Entry Share or Certificate surrendered in exchange therefor is registered, it shall be a condition of such exchange that the Person requesting such exchange shall pay to the Paying Agent any transfer or other Taxes required by reason of payment of the Merger Consideration to a Person other than the registered holder of the Book-Entry Share or Certificate surrendered, or shall establish to the reasonable satisfaction of the Paying Agent that such Tax has been paid or is not applicable.

(c) The Consideration Fund shall be invested by the Paying Agent as directed by Parent or the Surviving Corporation; provided, however, that any such investments shall be in money market mutual or similar funds having assets in excess of $10,000,000,000. Earnings on the Consideration Fund shall be the sole and exclusive property of Parent and the Surviving Corporation and shall be paid to Parent or the Surviving Corporation, as Parent directs. No investment of the Consideration Fund shall relieve Parent, the Surviving Corporation or the Paying Agent from promptly making the payments required by this Article III, and following any losses from any such investment, Parent shall promptly provide additional funds to the Paying Agent for the benefit of the holders of shares of Common Stock at the Effective Time in the amount of such losses, which additional funds will be deemed to be part of the Consideration Fund.

(d) At and after the Effective Time, there shall be no transfers on the stock transfer books of the Company of the shares of Common Stock 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 the Paying Agent for any reason, they shall be cancelled and exchanged for the Merger Consideration pursuant to this Article III, except as otherwise provided by Law.

(e) Any portion of the Consideration Fund (including the proceeds of any investments thereof) that remains unclaimed by the former shareholders of the Company one (1) year after the Effective Time shall be delivered to the Surviving Corporation. Any holders of Certificates or Book-Entry Shares who have not theretofore complied with this Article III with respect to such Certificates or Book-Entry Shares shall thereafter look only to the Surviving Corporation for payment of their claim for Merger Consideration in respect thereof.

(f) Notwithstanding the foregoing, neither the Paying Agent nor any party hereto shall be liable to any Person in respect of cash from the Consideration Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any Certificate or Book-Entry Share shall not have been surrendered prior to the date on

which any Merger Consideration in respect thereof would otherwise escheat to or become the property of any Governmental Entity, any such Merger Consideration in respect of such Certificate or Book-Entry Share shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation, and any holder of such Certificate or Book-Entry Share who has not theretofore complied with this Article III with respect thereto shall thereafter look only to the Surviving Corporation for payment of their claim for Merger Consideration in respect thereof.

(g) If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact (such affidavit shall be in a form reasonably satisfactory to Parent and the Paying Agent) by the Person claiming such certificate to be lost, stolen or destroyed, the Paying Agent shall issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration to which such Person is entitled in respect of such Certificate pursuant to this Article III.

Section 3.3 Shares of Dissenting Shareholders.

(a) Notwithstanding anything in this Agreement other than Section 3.3(b) to the contrary, any shares of Common Stock that are issued and outstanding immediately prior to the Effective Time and held by a shareholder who is entitled to dissent from the Merger under Chapter 23B.13 of the WBCA and who has exercised, when and in the manner required by Chapter 23B.13 of the WBCA to the extent so required prior to the Effective Time, such right to dissent and to obtain payment of the fair value of such shares under Chapter 23B.13 of the WBCA in connection with the Merger (“Dissenting Shares”) shall not be converted into the right to receive the Merger Consideration unless and until such shareholder shall have effectively withdrawn or lost (through failure to perfect or otherwise) such shareholder’s right to obtain payment of the fair value of such shareholder’s Dissenting Shares under Chapter 23B.13 of the WBCA, but shall instead be entitled only to such rights with respect to such Dissenting Shares as may be granted to such shareholder under Chapter 23B.13 of the WBCA. From and after the Effective Time, Dissenting Shares shall not be entitled to vote for any purpose or be entitled to the payment of dividends or other distributions (except dividends or other distributions payable to shareholders of record prior to the Effective Time). The Company shall promptly provide any notices of dissent to Parent.

(b) If any shareholder who holds Dissenting Shares effectively withdraws or loses (through failure to perfect or otherwise) such shareholder’s right to obtain payment of the fair value of such shareholder’s Dissenting Shares under Chapter 23B.13 of the WBCA, then, as of the later of the Effective Time and the occurrence of such effective withdrawal or loss, such shareholder’s shares of Common Stock shall no longer be Dissenting Shares and, if the occurrence of such effective withdrawal or loss is later than the Effective Time, shall be treated as if they had as of the Effective Time been converted into the right to receive Merger Consideration as set forth in subsection (a) of Section 3.1.

Section 3.4 Treatment of Stock Options; Restricted Shares.

(a) As soon as practicable following the date of this Agreement and to the extent necessary, the board of directors of the Company (or, if appropriate, any committee administering the Company Option Plans) shall adopt such resolutions and take such other actions as are required with respect to outstanding options to purchase shares of Common Stock issued pursuant to the Company Option Plans, to the extent vested and exercisable immediately prior to the Effective Time or as a result of the Merger (“Vested Options”), such that each Vested Option outstanding at the Effective Time shall cease to represent a right to acquire shares of Common Stock and shall instead represent only the right to receive the Merger Consideration for each share of Common Stock that would have been issuable upon exercise of the Vested Option prior to the Effective Time less the applicable exercise price for such share of Common Stock under such Vested Option (such net amount, the “Option Per Share Amount”). Parent shall promptly pay or cause to be paid immediately after the Effective Time to the holders of Vested Options as of immediately prior to the Effective Time the Option Per Share Amount (less any applicable tax withholding) for each share of Common Stock that would have been issued upon exercise of the Vested Options.

(b) At the Effective Time, each of the outstanding options to purchase shares of Common Stock issued pursuant to the Company Option Plans to the extent not vested or exercisable prior to or as a result of the consummation of the Merger (the “Unvested Options”) shall, without any further action on the part of any holder thereof, be converted into an option granted pursuant to the Parent Corporation 2001 Stock Plan, as amended and restated (the “Parent 2001 Stock Plan”), to purchase that number of shares of common stock, par value $0.00000625 per share, of Parent (the “Parent Common Shares”) determined by multiplying the number of Company Common Shares subject to such Unvested Option at the Effective Time by the Exchange Ratio (as defined below), at an exercise price per Parent Common Share equal to the exercise price per share of such Unvested Option immediately prior to the Effective Time divided by the Exchange Ratio (rounded up to the nearest whole cent) (a “Substituted Parent Option”). If the foregoing calculation results in a Substituted Parent Option being exercisable for a fraction of a Parent Common Share, then the number of Parent Common Shares subject to such option shall be rounded down to the nearest whole number of shares.

(c) The Substituted Parent Options shall have the same vesting schedule (including any acceleration of vesting as provided in the Company Option Plans) as the Unvested Options and otherwise shall have the terms and conditions as set forth in such Substituted Parent Options; provided that Parent shall convert Unvested Options into Substituted Parent Options in such a manner as to ensure that (i) the Substituted Parent Options are not subject to Section 409A of the Code as a result of the substitution and (ii) Substituted Parent Options received with respect to Unvested Options that were “incentive stock options” within the meaning of section 422 of the Code will satisfy the requirement of section 424(a) of the Code and continue to be “incentive stock options” within the meaning of section 422 of the Code. As a result of such conversion, the Substituted Parent Options shall be subject to all of the terms and conditions of the Parent 2001 Stock Plan and grant agreements for the Substituted Parent Options (rather than the terms and conditions of the plan and grant agreements under which the Unvested Options were originally issued). Prior to the Effective Time, Company shall take all actions (including causing its board of directors, the compensation committee of Company’s board of directors, or a

committee overseeing the Company Option Plans to take all actions) that are necessary to confirm that the Substituted Parent Options are “equivalent” and “comparable” options, as applicable, under the terms of the Company Option Plans or otherwise such that vesting in Unvested Options will not be accelerated as a result of the Merger, this Agreement, or the transactions contemplated hereby (the “Transactions”) (including the exchange of the Substituted Parent Options for the Unvested Options) and that are otherwise necessary to ensure that the Unvested Options may be substituted as provided in this Section 3.4(c). For purposes of this Agreement, “Exchange Ratio” shall mean the number determined by dividing the Merger Consideration by the average of the closing prices of a Parent Common Share as publicly reported for the Nasdaq Global Market System as of 4:00 p.m. Eastern Time for each of the 10 consecutive trading days immediately preceding the Effective Time.

(d) At the Effective Time, by virtue of the Merger, Company Restricted Shares outstanding immediately prior to the Effective Time shall be converted into that number of restricted shares (“Parent Restricted Shares”) or restricted stock units of Parent Common Shares (such restricted stock units together with Parent Restricted Shares, “Substitute Deferred Compensation”) with an equivalent after tax economic effect (and with no detrimental effect on the holder thereof) determined by multiplying the number of Company Restricted Shares by the Exchange Ratio. Any Substitute Deferred Compensation issued pursuant to this Section 3.4(d) shall be subject to the same terms and conditions as were applicable under such Company Restricted Shares (including the vesting schedule and any acceleration of vesting pursuant to any Company Option Plans) except to the extent changes to the terms and conditions are otherwise agreed to between Parent and the holder of the Parent Restricted Shares.

Section 6.3 Acquisition Proposals.

(a) The Company and its Subsidiaries will not, and will use their reasonable best efforts to cause their respective officers, directors, employees and other Representatives not to, directly or indirectly (i) initiate, encourage, facilitate, solicit, or participate or engage in any negotiations, inquiries, or discussions with respect to any Acquisition Proposal, (ii) in connection with any potential Acquisition Proposal, disclose or furnish any nonpublic information or data to any Person concerning the Company’s business or properties or afford any Person other than Parent or its Representatives access to its properties, books, or records, except as required by law or pursuant to a governmental request for information, (iii) enter into or execute, or propose to enter into or execute, any agreement relating to an Acquisition Proposal, or (iv) approve, endorse, recommend or make or authorize any public statement, recommendation, or solicitation in support of any Acquisition Proposal or any offer or proposal relating to an Acquisition Proposal other than with respect to the Merger. The Company will, and will direct its Representatives to, cease immediately and cause to be terminated all discussions and negotiations that commenced prior to the date of this Agreement regarding any proposal that constitutes, or could reasonably be expected to lead to, an Acquisition Proposal, and shall request that all confidential or proprietary information previously furnished to any such third parties be promptly returned or destroyed.

(b) Notwithstanding anything to the contrary contained in this Agreement, in the event that the Company is contacted by any third party expressing an interest in discussing a possible Acquisition Proposal or receives an unsolicited Acquisition Proposal, the Company and its board of directors may participate in discussions or negotiations (including, as a part thereof, making any counterproposal) with, or furnish any non-public information to, any Person or Persons (but only after such Person enters into a customary confidentiality agreement

with the Company (which confidentiality agreement (i) must be no less restrictive in the aggregate to the Person making such proposal than the Confidentiality Agreement, (ii) may not provide for an exclusive right to negotiate with the Company and (iii) may not restrict the Company from complying with this Section 6.3(b))) making such contact or making such Acquisition Proposal and their respective Representatives , prior to Company Shareholder Approval, in each case, if and to the extent that (A) the Company’s board of directors determines in good faith, by resolution duly adopted, after consultation with its financial advisors and outside legal counsel, that such Person or Persons have submitted to the Company an Acquisition Proposal that is, or would reasonably be expected to lead to, a Superior Proposal, and (B) the Company’s board of directors determines in good faith, by resolution duly adopted, after consultation with outside legal counsel, that the failure to participate in such discussions or negotiations, furnish such information, enter into any agreement related to any Acquisition Proposal or accept any offer or proposal relating to an Acquisition Proposal would reasonably be expected to result in a breach of the directors’ fiduciary duties under applicable Law. In addition, nothing herein shall restrict the Company from complying with its disclosure obligations with regard to any Acquisition Proposal under applicable Law.

(c) The Company will as promptly as reasonably practicable (and in any event within 24 hours after receipt) notify Parent of the receipt by the Company of any Acquisition Proposal or of any expression of interest from a Person in discussing a possible Acquisition Proposal, and the identity of the Person or Persons making such Acquisition Proposal or expression of interest. The Company will provide Parent with a correct and complete copy of any confidentiality agreement entered into pursuant to Section 6.3(b) within 24 hours after execution thereof. The Company will provide Parent with 24 hours prior notice (or such lesser prior notice as is provided to the members of its board of directors) of any meeting of its board of directors at which its board of directors would reasonably be expected to consider any Acquisition Proposal or any such inquiry or to consider providing nonpublic information to any Person. The Company shall notify Parent, in writing, of any decision of its board of directors as to whether to consider any Acquisition Proposal or to enter into discussions or negotiations concerning any Acquisition Proposal or to provide non-public information with respect to the Company to any Person in compliance with the provisions of this Section 6.3, which notice shall be given as promptly as practicable after such meeting (and in any event no later than 24 hours after such determination was reached). The Company will (i) provide Parent with oral and written notice setting forth all such information as is reasonably necessary to keep Parent currently informed in all material respects of the status and material terms of any such Acquisition Proposal and of any material amendments or proposed material amendments thereto (including negotiations contemplated by Section 6.3(b)), (ii) promptly provide Parent a copy of all written information subsequently provided to, by or on behalf of such Person or group in connection with any Acquisition Proposal and (iii) promptly (and in any event within 24 hours of such determination) notify Parent of any determination by the Company’s board of directors that such Acquisition Proposal constitutes a Superior Proposal.

(d) Subject to Section 6.3(e), unless and until this Agreement has been terminated in accordance with Section 8.1, neither the board of directors of the Company nor any committee thereof shall, directly or indirectly, (A)(i) withdraw or modify, or propose publicly to withdraw or modify, in a manner adverse to the Parent or Sub, the approval or recommendation or declaration of advisability by the board of directors of the Company or any such committee

thereof of the Merger as set forth in Section 6.7; (ii) approve, adopt, or recommend, or propose publicly to approve, adopt, or recommend, any Acquisition Proposal or (iii) in the event of a tender offer or exchange offer for any outstanding Company Common Shares, fail to recommend against acceptance of such tender offer or exchange offer by Company’s shareholders within ten (10) Business Days of the commencement thereof (for the avoidance of doubt, the taking of no position or a neutral position by the board of directors of the Company in respect of the acceptance of any tender offer or exchange offer by its shareholders shall constitute a failure to recommend against any such offer) (any action described in clauses (i)-(iii) being referred to as a “Change of Recommendation”) or (B) approve or recommend, or publicly propose to approve or recommend, or allow the Company to execute or enter into, any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement, or other similar agreement, arrangement, or understanding (i) constituting or related to, or that is intended to or would reasonably be expected to lead to, any Acquisition Proposal or (ii) requiring it to abandon, terminate, or fail to consummate the Merger or any other transaction contemplated by this Agreement.

(e) Notwithstanding the foregoing, in the event that, prior to the Company Special Meeting, the Company’s board of directors receives a Superior Proposal that has not been withdrawn, the Company’s board of directors may, if the Company’s board of directors by resolution duly adopted determines in good faith, after consultation with its outside legal counsel, that the failure to take such action would reasonably be expected to result in a breach of the directors’ fiduciary duties under applicable Law, may make a Change of Recommendation, approve or recommend such Superior Proposal or terminate this Agreement as permitted pursuant to the terms of Section 8.1(c)(ii); provided that:

(i) the Company notifies the Parent that it intends to take such action, which notice must specify the reasons for taking such action, the identity of the party making such proposal and the material terms and conditions of such proposal; and

(ii) Parent shall not have proposed, within three (3) Business Days after receipt of such notice from the Company, to amend this Agreement to provide for terms the board of directors of the Company determines in good faith, after consultation with its financial advisor, to be as favorable as or superior to those of the Superior Proposal.

(f) Nothing contained in this Section 6.3 shall prohibit the Company or its board of directors from taking and disclosing to the Company’s shareholders a position with respect to a tender offer or exchange offer by a third party or from taking any action or making any disclosure required by applicable Law; provided that the content of the disclosure complies with this Section 6.3.

Section 6.4 Employee Benefits.

(a) For the benefit of Employees, until the earlier of six (6) months after the Effective Time or June 30, 2008, Parent agrees to (i) maintain or cause its Subsidiaries (including the Surviving Corporation) to maintain for each eligible Employee the amount of Employees’ base salary or wage rates, equity compensation, incentive compensation opportunity and other cash compensation that, in the aggregate, are not less than those in effect for such Employee on the date hereof and (ii) either (A) maintain or cause its Subsidiaries (including the Surviving Corporation) to maintain the Benefit Plans (other than the Company Option Plans and ESPP) at the benefit levels in effect on the date hereof or (B) provide or cause its Subsidiaries (including the Surviving Corporation) to provide employee benefits (including, without limitation, retirement, health and life insurance benefits) that, in the aggregate, are no less favorable to each Employee than those in effect for such Employee on the date hereof.

(b) As of the Effective Time, Parent shall honor or cause to be honored, in accordance with their terms, all Benefit Agreements and all incentive, bonus, individual benefit, employment, employment termination, severance and other compensation agreements, plans and arrangements, including the Company’s executive change-in-control and general severance and retention plans (collectively, the “CIC Plans”), in each case existing immediately prior to the execution of this Agreement, that are between the Company or any of its Subsidiaries and any current or former director or Employee thereof or for the benefit of any such current or former director or Employee. As of the Effective Time, Parent shall honor or cause to be honored all Post-Signing Stabilization Plans. Parent shall not, and shall cause the Surviving Corporation not to, terminate the CIC Plans or Post-Signing Stabilization Plans or amend them in any manner without the consent of the affected current or former Employee for a period of two (2) years immediately following the Effective Time. Parent hereby guarantees the payment and performance by the Surviving Corporation of such obligations assumed by Surviving Corporation pursuant to this Section 6.4(b). In addition, Parent agrees that if an Employee thereof is employed immediately after the Effective Time with the Parent or any Subsidiary thereof (including the Surviving Corporation) and their position with the Surviving Corporation is eliminated or their employment is involuntarily terminated by Parent without Cause within the first twelve (12) months immediately following the Effective Time, such Employee shall receive additional vesting in Substituted Parent Options as if the Employee were employed with Parent or a Subsidiary thereof (including the Surviving Corporation) for an additional twelve (12) months after his or her actual date of termination of employment.

(c) With respect to each benefit plan, program, practice, policy or arrangement maintained by Parent or its Subsidiaries that are located within the United States (including the Surviving Corporation) following the Effective Time and in which any of the Employees working in the United States participate (the “Parent Plans”), for purposes of determining eligibility to participate and vesting, service with the Company and its Subsidiaries (or predecessor employers to the extent the Company provides past service credit) shall be treated as service with Parent and its Subsidiaries. Each applicable Parent Plan shall waive eligibility waiting periods, evidence of insurability requirements and pre-existing condition limitations to the extent (i) waived or not included under the corresponding Benefit Plan and (ii) permitted by the applicable insurance policy under the Parent Plan.

Section 6.5 Publicity. The initial press release by each of Parent and the Company with respect to the execution of this Agreement shall be acceptable to Parent and the Company. Neither the Company nor Parent (nor any of their respective Affiliates) shall issue any other press release or make any other public announcement with respect to this Agreement or the transactions contemplated hereby without the prior agreement of the other party, except as may be required by Law or by any listing agreement with a national securities exchange, in which case the party proposing to issue such press release or make such public announcement shall use its reasonable best efforts to consult in good faith with the other party before making any such public announcements; provided that the Company will no longer be required to obtain the prior agreement of or consult with Parent in connection with any such press release or public announcement if the Company’s board of directors has effected a Change of Recommendation or in connection with any such press release or public announcement pursuant to Section 6.3(f).

Section 6.6 Directors’ and Officers’ Insurance and Indemnification.

(a) From and after the Effective Time, Parent shall, and shall cause the Surviving Corporation to, indemnify and hold harmless the individuals who at any time prior to the Effective Time were directors or officers of the Company or any of its present or former Subsidiaries or corporate parents (the “Indemnified Parties”) against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages or liabilities in connection with actions or omissions occurring at or prior to the Effective Time (including the transactions contemplated by this Agreement) to the fullest extent permitted by Law, and Parent shall, and shall cause the Surviving Corporation to, promptly advance expenses as incurred to the fullest extent permitted by Law. The articles of incorporation and bylaws of the Surviving Corporation shall contain the provisions with respect to indemnification and advancement of expenses set forth in the articles of incorporation and bylaws of the Company as amended, restated and in effect on the date of this Agreement, which provisions shall not be amended, repealed or otherwise modified in any manner that would adversely affect the rights thereunder of the Indemnified Parties, unless such modification is required by Law.

(b) Parent shall cause to be maintained in effect for not less than six (6) years from the Effective Time the current policies of directors’ and officers’ liability insurance and fiduciary liability insurance maintained by the Company and the Company’s Subsidiaries for the Indemnified Parties and any other employees, agents or other individuals otherwise covered by such insurance policies prior to the Effective Time (collectively, the “Insured Parties”) with respect to matters occurring at or prior to the Effective Time (including the transactions contemplated by this Agreement); provided that in lieu of the purchase of such insurance by Parent or the Surviving Corporation, the Company may at its option prior to the Effective Time purchase a six-year run-off (Extended Reporting Period) program for directors’ and officers’ liability insurance and fiduciary liability insurance.

(c) This Section 6.6 is intended to benefit the Insured Parties and the Indemnified Parties, and shall be binding on all successors and assigns of Parent, Sub, the Company and the Surviving Corporation. Parent hereby guarantees the payment and performance by the Surviving Corporation of the indemnification and other obligations pursuant to this Section 6.6 and the articles of incorporation and bylaws of the Surviving Corporation.

(d) In the event that Parent, the Surviving Corporation or any of their successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving Person of such consolidation or merger or (ii) transfers or conveys a majority of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors, assigns and transferees of Parent or the Surviving Corporation or their respective successors or assigns, as the case may be, assume the obligations set forth in this Section 6.6.

So long as the Company’s board of directors shall not have effected a Change of Recommendation, (a) the Company shall take all action necessary in accordance with applicable Law and its articles of incorporation and bylaws and Nasdaq rules to call, give notice of, convene and hold a special meeting of the Company’s shareholders (including any adjournment or postponement thereof, the “Company Special Meeting”) as soon as practicable following the date hereof for the purpose of approving this Agreement, and (b) in connection with the Company Special Meeting, as soon as practicable after the date hereof the Company shall prepare and file with the SEC a proxy statement (together with all amendments and supplements thereto, the “Proxy Statement”) relating to the Merger and this Agreement and furnish the information required to be provided to the shareholders of the Company pursuant to the WBCA and the Exchange Act.

Section 6.8 Commercially Reasonable Efforts; HSR Act Filings.

(a) Upon the terms and subject to the conditions set forth in this Agreement, the Company and Parent shall each use their commercially reasonable efforts to promptly, unless prohibited by Law (i) take, or to cause to be taken, all actions, and to do, or to cause to be done, and to assist and cooperate with the other parties in doing all things necessary, proper or advisable under applicable Law or otherwise to consummate and make effective the transactions contemplated by this Agreement; (ii) obtain from any Governmental Entities any actions, non-actions, clearances, waivers, consents, approvals, permits or orders required to be obtained by the Company, Parent or any of their respective Subsidiaries in connection with the authorization, execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby; (iii) promptly make all necessary registrations and filings, and thereafter make any other required submissions, with respect to this Agreement and the Merger required under (A) any applicable federal or state securities Laws, (B) the HSR Act and any applicable competition, antitrust or investment Laws of jurisdictions other than the United States (for purposes of this Section 6.8(a)(iii)(B), “promptly” shall mean within ten Business Days of the date of this Agreement), and (C) any other applicable Law; provided, however, that the Company and Parent will cooperate with each other in connection with the making of all such filings, including providing copies of all such filings and attachments to outside counsel for the non-filing party; (iv) furnish all information required for any application or other filing to be

made pursuant to any applicable Law in connection with the transactions contemplated by this Agreement; (v) keep the other party informed in all material respects of any material communication received by such party from, or given by such party to, any Governmental Entity and of any material communication received or given in connection with any proceeding by a private party, in each case relating to the transactions contemplated by this Agreement; (vi) permit the other parties to review any material communication delivered to, and consult with the other party in advance of any meeting or conference with, any Governmental Entity relating to the transactions contemplated by this Agreement or in connection with any proceeding by a private party relating thereto, and giving the other party the opportunity to attend and participate in such meetings and conferences (to the extent permitted by such Governmental Entity or private party); (vii) avoid the entry of, or have vacated or terminated, any decree, order, or judgment that would restrain, prevent or delay the Closing, including defending any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated hereby; and (viii) execute and deliver any additional instruments necessary to consummate the transactions contemplated by this Agreement. No parties to this Agreement shall consent to any voluntary delay of the Closing at the behest of any Governmental Entity without the consent of the other parties to this Agreement, which consent shall not be unreasonably withheld. Parent agrees to take, or to cause to be taken, any and all steps and to make any and all undertakings necessary to avoid or eliminate each and every impediment under any antitrust, merger control, competition, or trade regulation Law that may be asserted by any Governmental Entity with respect to the Merger so as to enable the Closing to occur as soon as reasonably possible (and in any event, no later than the Termination Date (as defined herein)). Notwithstanding anything to the contrary in this Section 6.8(a), (x) neither Parent nor any of its subsidiaries shall be required to divest any of their respective material businesses, product lines, or assets, or to take or agree to take any other material action or agree to any material limitation on its business practices, and (y) Company shall not be required to divest material businesses, product lines, or assets, or to take or agree to take any other material action or agree to any material limitation on its business practices.

(b) Each of the Company, Parent and Sub shall give prompt notice to the other parties of (i) any written notice or other communication from any Governmental Entity in connection with the Merger and (ii) any change or development that is reasonably likely to have a Company Material Adverse Effect or a Parent Material Adverse Effect.

Section 6.9 Section 16 Matters. Prior to the Effective Time, the board of directors of Parent, or an appropriate committee of non-employee directors, shall adopt a resolution consistent with the interpretative guidance of the SEC so that the acquisition of the Substituted Options pursuant to this Agreement shall be an exempt transaction for purposes of Section 16 of the Exchange Act by any officer or director of the Company who may become a covered person of Parent for purposes of Section 16 of the Exchange Act.

Section 6.10 Filing of Form S-8. Parent has filed or agrees to file no later than the Effective Time a registration statement on Form S-8 (or any successor or other appropriate form) with respect to the shares of Parent’s common stock issuable with respect to Parent Restricted Shares and Substitute Options and shall use all reasonable efforts to maintain the effectiveness of such registration statement or registration statements (and maintain the

current status of the prospectus or prospectuses contained therein) for so long as the Substitute Options acquired in accordance with this Agreement remain outstanding.

Section 6.11 ESPP. The Company’s ESPP shall continue to be operated in accordance with its terms and past practice for the current Purchase Period (as defined in the ESPP) (“Purchase Period”); provided that if the Closing is expected to occur prior to the end of the current Purchase Period, the Company shall take action to provide for an earlier Purchase Date (as defined in the ESPP) in accordance with Section 21.2 of the ESPP. Such earlier Purchase Date shall be as reasonably close to the Closing Date as is administratively practicable. The Company shall suspend the commencement of any future Purchase Periods under the ESPP unless and until this Agreement is terminated and shall terminate the ESPP prior to the Closing Date.

(c) If (i) this Agreement is terminated by Parent or the Company (A) pursuant to Section 8.1(b)(i) due to the failure to satisfy the conditions to Closing set forth in Sections 7.1(b) or (c) due to the failure to receive any required antitrust or competition consent or clearance from a Governmental Entity of competent jurisdiction or any action by any Governmental Entity of competent jurisdiction to prevent the Merger for antitrust, competition, privacy or security reasons, or (B) pursuant to Section 8.1(b)(ii), (ii) all other conditions to

Nothing in this section shall be deemed to constitute consent to the manner or address for service of process in connection with any legal proceeding, including litigation arising out of or in connection with this Agreement.

Section 9.4 Interpretation. The parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement.

The inclusion of any item in the Company Disclosure Schedule shall not be deemed to be an admission or evidence of materiality of such item, nor shall it establish any standard of materiality for any purpose whatsoever.

Section 9.5 Counterparts. This Agreement may be executed in multiple counterparts, each of which when executed and delivered shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

Section 9.6 Entire Agreement; Third-Party Beneficiaries. This Agreement (including the Company Disclosure Schedule and the exhibits and instruments referred to herein) and the Confidentiality Agreement (a) constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof and (b) except as provided in Article III on and after the Effective Time and Section 6.4 and Section 6.6, are not intended to confer upon any Person other than the parties hereto any rights or remedies hereunder.

Section 9.7 Severability.

Section 9.8 Governing Law. This Agreement shall be governed and construed in accordance with the laws of the State of Washington applicable to contracts to be made and performed entirely therein without giving effect to the principles of conflicts of law thereof or of any other jurisdiction.

However, the foregoing shall not limit the right of a party to effect service of process on the other party by any other legally available method.

Section 9.11 Specific Performance. Each of the parties hereto acknowledges and agrees that, in the event of any breach of this Agreement, each nonbreaching party would be irreparably and immediately harmed and could not be made whole by monetary damages.
