WHEREAS, the board of directors of each of Parent, Purchaser and the Company has approved the acquisition of the Company by Parent on the terms and conditions set forth in this Agreement;

WHEREAS, on the terms and subject to the conditions set forth herein, Purchaser has agreed to commence a tender offer (the “Offer”) to purchase all outstanding Company Shares, at a price of $85.00 per Company Share, in cash without interest (such price, or any higher price as may be paid in the Offer in accordance with this Agreement, the “Offer Price”);

WHEREAS, following consummation of the Offer, on the terms and subject to the conditions set forth herein Purchaser shall merge with and into the Company (the “Merger”) and each Company Share that is issued and outstanding immediately prior to the Effective Time (other than Company Shares held in the treasury of the Company or owned by Parent, Purchaser or any direct or indirect wholly-owned Subsidiary of Parent or the Company immediately prior to the Effective Time, which will be canceled with no consideration issued in exchange therefor, and other than Appraisal Shares) will be canceled and converted into the right to receive cash in an amount equal to the Offer Price (the “Merger Consideration”), all upon the terms and conditions set forth herein;

WHEREAS, the Company Board has, on the terms and subject to the conditions set forth herein, unanimously and duly adopted resolutions (i) determining that the transactions contemplated by this Agreement are advisable and fair to, and in the best interests of, the Company and its stockholders, (ii) adopting and approving this Agreement and the transactions contemplated hereby, including the Offer, the Merger and the “agreement of merger” (as such term is used in Section 251 of the Delaware General Corporation Law (the “DGCL”)), in accordance with the DGCL, (iii) directing that the “agreement of merger” (as such term is used in Section 251 of the DGCL) contained in this Agreement be submitted to the stockholders of the Company for adoption (unless the Merger is consummated in accordance with Section 253 of the DGCL as contemplated herein), and (iv) recommending that the Company’s stockholders accept the Offer, tender their Company Shares to Purchaser pursuant to the Offer, and adopt the “agreement of merger” (as such term is used in Section 251 of the DGCL) set forth in this Agreement;

WHEREAS, the board of directors of Parent and Purchaser have, on the terms and subject to the conditions set forth herein, unanimously approved and declared advisable this Agreement and the transactions contemplated hereby, including the Offer and the Merger, and Parent, in its capacity as the sole stockholder of Purchaser, has adopted the “agreement of merger” set forth in this Agreement, in each case, in accordance with the DGCL; and

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements herein contained, and intending to be legally bound hereby, Parent, Purchaser and the Company hereby agree as follows:

SECTION 1. THE OFFER

1.1 The Offer

(a) Provided that this Agreement shall not have previously been validly terminated in accordance with Section 7, as promptly as practicable after the date hereof, but in any event within ten business days after the date of this Agreement, Purchaser shall commence (within the meaning of Rule 14d-2 under the Exchange Act) the Offer for all of the outstanding Company Shares (including any Company Shares subject to repurchase rights in favor of the Company) for consideration per Company Share consisting of the Offer Price. (The date on which Purchaser commences the Offer, within the meaning of Rule 14d-2 under the Exchange Act, is referred to in this Agreement as the “Offer Commencement Date”).

(b) As promptly as practicable on the later of: (i) the earliest date as of which Purchaser is permitted under applicable Legal Requirements to accept for payment Company Shares tendered pursuant to the Offer; and (ii) the earliest date as of which each of the conditions set forth in Annex I (the “Offer Conditions”) shall have been satisfied or waived, Purchaser shall (and Parent shall cause Purchaser to) accept for payment all Company Shares tendered pursuant to the Offer (and not validly withdrawn). The obligation of Purchaser to accept for payment Company Shares tendered pursuant to the Offer shall be subject only to the satisfaction or waiver of each of the Offer Conditions (and shall not be subject to any other conditions). As promptly as practicable after the acceptance for payment of any Company Shares tendered pursuant to the Offer, Purchaser shall pay for such Company Shares.

(c) Notwithstanding anything to the contrary contained in this Agreement, neither Parent nor Purchaser shall (without the prior written consent of the Company):

(i) change or waive the Minimum Condition (as defined in Annex I);

(ii) decrease the number of Company Shares sought to be purchased by Purchaser in the Offer;

(iii) reduce the Offer Price;

(iv) extend or otherwise change the expiration date of the Offer (except to the extent required pursuant to Section 1.1(d));

(v) change the form of consideration payable in the Offer; or

(vi) amend, modify or supplement any of the Offer Conditions or terms of the Offer in a manner that adversely affects, or would reasonably be expected to adversely affect, the holders of Company Shares.

(d) Unless extended as provided in this Agreement, the Offer shall expire on the date (the “Initial Expiration Date”) that is 20 business days (calculated as set forth in Rule 14d-1(g)(3) under the Exchange Act) after the Offer Commencement Date. Notwithstanding the foregoing, if, on the Initial Expiration Date or any subsequent date as of which the Offer is scheduled to expire, any Offer Condition is not satisfied and has not been waived, then Purchaser, without the consent of the Company, may (and, to the extent requested by the Company from time to time, shall) extend (and re-extend) the Offer and its expiration date for one or more periods ending no later than the Outside Date, to permit such Offer Condition to be satisfied; provided, however, that no individual extension shall be for a period of more than 10 business days without the prior written consent of the Company. The Offer may be terminated prior to its expiration date (as such expiration date may be extended and re-extended in accordance with this Agreement), but only if this Agreement is validly terminated in accordance with Section 7.

(e) Purchaser may, in its discretion, elect to provide for a subsequent offering period (and one or more extensions thereof) (and, if immediately following the Acceptance Time (as defined in Section 1.4(a)), Parent, Purchaser and their respective Subsidiaries and Affiliates own more than 80% of the Company Shares outstanding at that time (which shares beneficially owned shall include shares tendered in the Offer and not withdrawn), to the extent requested by the Company, Purchaser shall provide for a subsequent offering period of at least 10 business days) in accordance with Rule 14d-11 under the Exchange Act following the Acceptance Time.

(f) The Offer Price shall be adjusted to the extent appropriate to reflect the effect of any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction with respect to Company Shares occurring or having a record date on or after the date of this Agreement and prior to the payment by Purchaser for the Company Shares.

1.2 Actions of Parent and Purchaser.

(a) On the Offer Commencement Date Parent shall: (i) cause to be filed with the SEC a Tender Offer Statement on Schedule TO with respect to the Offer, which will contain Purchaser’s offer to purchase and related letter of transmittal (the forms of which shall be reasonably acceptable to the Company) and the related form of summary advertisement (such Tender Offer Statement on Schedule TO, all exhibits, amendments and supplements thereto being referred to collectively in this Agreement as the “Offer Documents”) and (ii) cause the Offer Documents to be disseminated to holders of Company Shares to the extent required by applicable Legal Requirements. Parent and Purchaser shall cause the Offer Documents to comply in all material respects with the applicable requirements of the Exchange Act and the rules and regulations thereunder. The Company and its counsel shall be given a reasonable opportunity to review and comment on the Offer Documents (including any amendment or supplement thereto) prior to the filing thereof with the SEC. Parent and Purchaser shall promptly provide the Company and its counsel with a copy or a description of any comments received by Parent or Purchaser (or by counsel to Parent or Purchaser) from the SEC or its staff with respect to the Offer Documents. Each of Parent and Purchaser shall respond as promptly as practicable to any comments of the SEC or its staff with respect to the Offer Documents or the Offer.

(b) To the extent required by the applicable requirements of the Exchange Act and the rules and regulations thereunder: (i) each of Parent, Purchaser and the Company shall correct promptly any information provided by it for use in the Offer Documents if such information shall have become false or misleading in any material respect; and (ii) each of Parent and Purchaser shall take all steps necessary to promptly cause the Offer Documents, as supplemented or amended to correct such information, to be filed with the SEC and to be disseminated to holders of Company Shares. The Company shall promptly furnish to Parent all information concerning the Company that may be reasonably requested by Parent in connection with any action contemplated by Section 1.2(a) or (b). No representation is made by Parent or Purchaser with respect to information supplied by the Company for inclusion in the Offer Documents.

(c) Without limiting the generality of Section 8.10, Parent shall cause to be provided to Purchaser all of the funds necessary to purchase any Company Shares that Purchaser becomes obligated to purchase pursuant to the Offer, and shall cause Purchaser to perform, on a timely basis, all of Purchaser’s obligations under this Agreement.

1.3 Actions of the Company.

(a) The Company hereby approves of and consents to the Offer.

(b) On the Offer Commencement Date, the Company shall file with the SEC and (following or contemporaneously with the initial dissemination of the Offer Documents to holders of Company Shares to the extent required by applicable federal securities laws) disseminate to holders of Company Shares a Solicitation/Recommendation Statement on Schedule 14D-9 (together with any amendments or supplements thereto, the “Schedule 14D-9”) that, subject to Section 5.3(c), shall contain the Company Recommendation. Except in connection with a Company Change in Recommendation made in accordance with Section 5.3(c), Parent and its counsel shall be given a reasonable opportunity to review and comment on the Schedule 14D-9 (including any amendment or supplement thereto) prior to the filing thereof with the SEC. The Company shall: (i) promptly provide Parent and its counsel with a copy of any written comments and a description of any oral comments received by the Company (or its counsel) from the SEC or its staff with respect to the Schedule 14D-9; (ii) except with respect to disclosure made relating to a Company Change in Recommendation in accordance with Section 5.3(c), give Parent and its counsel a reasonable opportunity to review and comment on any response formulated in connection with such comments prior to the filing thereof with the SEC; and (iii) respond promptly to any such comments. To the extent required by the applicable requirements of the Exchange Act and the rules and regulations thereunder: (A) each of Parent, Purchaser and the Company shall promptly correct any information provided by it for use in the Schedule 14D-9 if such information shall have become false or misleading in any material respect; and (B) the Company shall take all steps necessary to cause the Schedule 14D-9, as supplemented or amended to correct such information, to be filed with the SEC. Parent and Purchaser shall promptly furnish to the Company all information concerning Parent or Purchaser that may be reasonably requested in connection with any action contemplated by this Section 1.3(b). To the extent requested by the Company, Parent shall cause the Schedule 14D-9 to be mailed or otherwise disseminated to the Company’s stockholders together with the Offer Documents disseminated to the Company’s stockholders.

(c) In connection with the Offer, the Company shall instruct its transfer agent to furnish to Purchaser a list, as of the most recent practicable date, of the record holders of Company Shares and their addresses, as well as mailing labels containing such names and addresses. The Company will furnish Purchaser with such additional information (including any security position listings in the Company’s possession or reasonably obtainable by the Company) and assistance as Purchaser may reasonably request for purposes of communicating the Offer to the record holders and beneficial holders of Company Shares. All information furnished in accordance with this Section 1.3(c) shall be held in confidence by Parent and Purchaser in accordance with the requirements of the letter agreement, dated May 11, 2006, between Parent and the Company, as amended on June 2, 2006 (the “Confidentiality Agreement”), and shall be used by Parent and Purchaser only in connection with the communication of the Offer and the dissemination of any proxy or information statement relating to the Merger to the holders of Company Shares.

1.4 Board of Directors.

(a) After the first time that Purchaser accepts for payment any Company Shares tendered pursuant to the Offer (the “Acceptance Time”), and at all times thereafter, the Company will, upon Parent’s request and subject to compliance with applicable Legal Requirements, take all actions necessary to cause persons designated by Parent to become directors of the Company so that the total number of such persons equals that number of directors, rounded up to the next whole number, determined by multiplying: (i) the total number of directors on the Company Board (after giving effect to the directors elected or designated by Parent in accordance with this Section 1.4(a)); by (ii) the percentage that the number of Company Shares beneficially owned by Parent, Purchaser or any of their respective Affiliates bears to the total number of Company Shares outstanding at the Acceptance Time (determined on a fully-diluted basis but disregarding any unvested stock options and other unvested rights to acquire Company Shares). The Company will take all actions necessary to permit Parent’s designees to be elected to the Company Board in accordance with this Section 1.4(a), including using reasonable efforts to secure the resignation of directors, promptly filling vacancies or newly created directorships on the Company Board, increasing the size of the Company Board, and/or amending the bylaws of the Company; provided, however, that prior to the Effective Time, the Company Board shall always have at least two Continuing Directors. The Company shall, upon Parent’s request following the Acceptance Time, and at all times thereafter, also cause Persons designated by Parent to constitute the same percentage (rounded up to the next whole number) as is on the Company Board of (i) each committee of the Company Board, (ii) each board of directors (or similar body) of each Subsidiary of the Company and (iii) each committee (or similar body) of each such board, in each case to the extent permitted by applicable Legal Requirements and the Marketplace Rules of the NASDAQ Global Select Market. Upon the election or appointment of all of Parent’s designees to the Company Board in accordance with this Section 1.4(a), the Company shall take all action necessary to elect to be treated as a “controlled company” as defined by NASDAQ Marketplace Rule 4350(c) and make all necessary filings and disclosures associated with such status. The provisions of this Section 1.4(a) are in addition to and shall not limit any rights that any of Purchaser, Parent or any of their respective affiliates may have as a record holder or beneficial owner of Company Shares as a matter of applicable Legal Requirements with respect to the election of directors or otherwise.

(b) The Company’s obligation to cause Parent’s designees to be elected or appointed to the Company Board shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1 thereunder. The Company shall promptly take all actions, and shall include in the Schedule 14D-9 such information with respect to the Company and its officers and directors, as Section 14(f) of the Exchange Act and Rule 14f-1 thereunder require in order to fulfill its obligations under this Section 1.4, so long as Parent shall have provided to the Company all information with respect to Parent and its designees, officers, directors and Affiliates required by Section 14(f) of the Exchange Act and Rule 14f-1 thereunder. Parent shall promptly supply to the Company in writing, and shall be solely responsible for, all such information.

1.5 Actions by Directors. Following the election or appointment of Parent’s designees to the Company Board pursuant to Section 1.4(a), and until the Effective Time, the approval of a majority of the Continuing Directors shall be required to authorize: (i) any amendment to or termination of this Agreement by the Company; (ii) any amendment to the Company’s certificate of incorporation; (iii) any extension of time for the performance of any of the obligations or other acts of Parent or Purchaser; (iv) any waiver of compliance with any covenant of Parent or Purchaser or any condition to any obligation of the Company or any waiver of any right of the Company under this Agreement; (v) any Company Change in Recommendation; and (vi) any other consent or action by the Company Board with respect to this Agreement, the Offer or the Merger. The authorization of any such matter by a majority of the Continuing Directors shall constitute the authorization of such matter by the Company Board, and no other action on the part of the Company or any other director of the Company shall be required to authorize such matter.

1.6 Top-Up Option.

(a) The Company hereby grants to Purchaser an irrevocable option (the “Top-Up Option”), exercisable only upon the terms and subject to the conditions set forth herein, to purchase, at a price per share equal to the Offer Price, that number of Company Shares (the “Top-Up Option Shares”) equal to the lesser of (x) the lowest number of Company Shares that, when added to the number of Company Shares owned by Parent, Purchaser and their respective Subsidiaries and Affiliates at the time of such exercise, shall constitute ten thousand (10,000) shares more than 90% of the Company Shares then outstanding (after giving effect to the issuance of the Top-Up Option Shares) and (y) an aggregate number of Company Shares that is equal to 19.9% of the Company Shares issued and outstanding as of the date hereof; provided, however, that the Top-Up Option shall not be exercisable unless, (i) immediately prior to such exercise, Parent, Purchaser and their respective Subsidiaries and Affiliates own more than 80% of the Company Shares then outstanding and (ii) immediately after such exercise and the issuance of Company Shares pursuant thereto, Parent, Purchaser and their respective Subsidiaries and Affiliates own more than 90% of the Company Shares then outstanding; and provided, further, that in no event shall the Top-Up Option be exercisable for a number of Company Shares in excess of the Company’s total authorized and unissued Company Shares.

(b) Provided that no applicable Legal Requirement shall prohibit the exercise of the Top-Up Option or the issuance of the Top-Up Option Shares pursuant thereto, or otherwise make such exercise or issuance illegal, Purchaser may exercise and re-exercise the Top-Up Option multiple times, in whole but not in part, at any time or times after the Acceptance Time and prior to the earlier to occur of (i) the Effective Time and (ii) the termination of this Agreement pursuant to Section 7.

(c) Each time that Purchaser wishes to exercise the Top-Up Option, Purchaser shall send to the Company a written notice (a “Top-Up Exercise Notice”) specifying the denominations of the certificate or certificates evidencing the Top-Up Option Shares which the Purchaser wishes to receive, and the place, time and date for the closing of the purchase and sale pursuant to the Top-Up Option (a “Top-Up Closing”). The Company shall, promptly after receipt of a Top-Up Exercise Notice, deliver a written notice to the Purchaser confirming the number of Top-Up Option Shares and the aggregate purchase price therefore. At each Top-Up Closing, Purchaser shall pay the Company the aggregate price required to be paid for the Top-Up Option Shares issuable at such Top-Up Closing, by delivery of, at Purchaser’s option, (A) immediately available funds by wire transfer to an account designated by the Company, (B) a promissory note, bearing simple interest at 5% per annum, and due six months after the Top-Up Closing, or (C) any combination thereof. At each Top-Up Closing, the Company shall cause to be issued to Purchaser a certificate or certificates representing the Top-Up Option Shares issuable at such Top-Up Closing. Certificates representing Company Shares in connection with the Top-Up Option may include any legends that are required by federal or state securities laws.

Upon the terms and subject to the conditions set forth in this Agreement and in accordance with the DGCL, at the Effective Time (as defined in Section 2.3), Purchaser shall be merged with and into the Company, and the separate existence of Purchaser shall cease. The Company will continue as the surviving corporation in the Merger (the “Surviving Corporation”).

2.2 Effect of the Merger. The Merger shall have the effects set forth in this Agreement and in the applicable provisions of the DGCL. Without limiting the generality of the foregoing and subject thereto, at the Effective Time, all the property rights, privileges, immunities, powers and franchises of the Company and Purchaser shall vest in the Surviving Corporation and all debts, liabilities and duties of the Company and Purchaser shall become the debts, liabilities and duties of the Surviving Corporation.

As soon as practicable after the satisfaction or waiver of the conditions set forth in Section 6, the parties hereto shall cause a properly executed certificate of merger conforming to the requirements of the DGCL (the “Certificate of Merger”) to be filed with the Secretary of State of the State of Delaware. The Merger shall become effective at the time the Certificate of Merger is filed with the Secretary of State of the State of Delaware, or at such later time as is agreed to by the parties hereto and specified in the Certificate of Merger (the time at which the Merger becomes effective being referred to in this Agreement as the “Effective Time”). At 10:00 a.m. (Pacific time) on the date on which the Certificate of Merger is to be so filed, a closing shall be held at the offices of ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ (or such other place or time as Parent and the Company may jointly designate).

(a) the certificate of incorporation of the Surviving Corporation shall be amended and restated as of the Effective Time to conform to Exhibit B;

(c) the directors of the Surviving Corporation immediately after the Effective Time shall be the respective individuals who are directors of Purchaser immediately prior to the Effective Time; and

(d) the officers of the Surviving Corporation immediately after the Effective Time shall be the respective individuals who are officers of Purchaser immediately prior to the Effective Time.

2.5 Conversion of Company Shares.

(a) Subject to Section 2.8, at the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Purchaser, the Company or any stockholder of the Company:

(i) any Company Shares then held by the Company or any wholly owned Subsidiary of the Company (or held in the Company’s treasury) shall cease to exist, and no consideration shall be paid in exchange therefor;

(ii) any Company Shares then held by Parent, Purchaser or any other wholly owned Subsidiary of Parent shall cease to exist, and no consideration shall be paid in exchange therefor;

(iii) except as provided in clauses “(i)” and “(ii)” above, each Company Share then outstanding (including any outstanding Company Shares subject to any repurchase rights in favor of the Company, but excluding any Appraisal Shares), shall be converted into the right to receive the Merger Consideration, without interest; and

(iv) each share of common stock, par value $0.001 per share, of Purchaser then outstanding shall be converted into one share of the common stock of the Surviving Corporation.

(b) The Merger Consideration shall be adjusted to the extent appropriate to reflect the effect of any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction with respect to Company Shares occurring or having a record date on or after the date of this Agreement and prior to the Effective Time.

2.6 Closing of the Company’s Transfer Books. At the Effective Time: (a) all Company Shares outstanding immediately prior to the Effective Time shall cease to exist as provided in Section 2.5 and all holders of certificates representing Company Shares that were outstanding immediately prior to the Effective Time shall cease to have any rights as stockholders of the Company; and (b) the stock transfer books of the Company shall be closed with respect to all Company Shares outstanding immediately prior to the Effective Time. No further transfer of any such Company Shares shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, a valid certificate previously representing any of such Company Shares (a “Company Stock Certificate”) is presented to the Payment Agent (as defined in Section 2.7(a)) or to the Surviving Corporation or Parent, such Company Stock Certificate shall be canceled and shall be exchanged as provided in Section 2.7.

2.7 Payment for Company Shares.

(a) Prior to the Acceptance Time (i) Parent shall select a bank or trust company (reasonably acceptable to the Company) to act as payment agent with respect to the payment of the Merger Consideration (the “Payment Agent”) and (ii) Parent shall cause to be made available to the Payment Agent cash amounts sufficient to enable the Payment Agent to make payments pursuant to Section 2.5 to holders of Company Shares outstanding immediately prior to the Effective Time.

(b) Promptly after the Effective Time, Parent shall cause the Payment Agent to mail to each Person who was, immediately prior to the Effective Time, a holder of record of Company Shares described in Section 2.5(a)(iii) a form of letter of transmittal (reasonably acceptable to the Company) and instructions for use in effecting the surrender of Company Stock Certificates representing such Company Shares in exchange for payment therefor. Parent shall ensure that, upon surrender to the Payment Agent of each such Company Stock Certificate, together with a properly executed letter of transmittal, the holder of such Company Stock Certificate (or, under the circumstances described in Section 2.7(e), the transferee of the Company Shares represented by such Company Stock Certificate) shall promptly receive in exchange therefor the consideration to which such holder (or transferee) is entitled pursuant to Section 2.5(a)(iii).

(c) On or after the first anniversary of the Effective Time, Parent or the Surviving Corporation shall be entitled to cause the Payment Agent to deliver to Parent or the Surviving Corporation any funds made available by Parent to the Payment Agent which have not been disbursed to holders of Company Stock Certificates, and thereafter such holders shall be entitled to look only to Parent and the Surviving Corporation with respect to the consideration payable and issuable upon surrender of their Company Stock Certificates. Neither the Payment Agent, Parent nor the Surviving Corporation shall be liable to any holder of a Company Stock Certificate for any amount properly paid to a public official pursuant to any applicable abandoned property or escheat law. If any Company Stock Certificates shall not have been surrendered before the third anniversary of the Effective Time (or immediately prior to such earlier date on which any Merger Consideration payable in respect of such Company Stock Certificates would otherwise escheat to or become the property of any Governmental Entity), any such Merger Consideration in respect thereof shall, to the extent permitted by applicable Legal Requirements, become the property of Parent, free and clear of all claims or interest of any Person previously entitled thereto.

(d) If any Company Stock Certificate shall have been lost, stolen or destroyed, then, upon the making of an affidavit of that fact by the Person claiming such Company Stock Certificate to be lost, stolen or destroyed in a form reasonably satisfactory to Parent (together with an indemnity in form reasonably satisfactory to Parent against any claim that may be made against the Payment Agent or Parent or otherwise with respect to such certificate and, if required by Parent, the posting by such Person of a bond in such reasonable amount as Parent may direct to support such indemnity), Parent shall cause the Payment Agent to pay in exchange for such lost, stolen or destroyed Company Stock Certificate the consideration payable and issuable in respect thereof pursuant to this Agreement.

(e) In the event of a transfer of ownership of Company Shares which is not registered in the transfer records of the Company, the consideration may be paid and issued with respect to such Company Shares to a transferee of such Company Shares if the Company Stock Certificate representing such Company Shares is presented to the Payment Agent, accompanied by all documents reasonably required by the Payment Agent to evidence and effect such transfer and to evidence that any applicable stock transfer taxes relating to such transfer have been paid.

(f) The Surviving Corporation or Parent shall bear and pay all charges and expenses, including those of the Payment Agent, incurred in connection with the exchange of the Company Shares.

(g) Parent, the Surviving Corporation and the Payment Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to the Offer, the Merger or this Agreement to any holder of Company Shares or Company Options such amounts as Parent, the Surviving Corporation or the Payment Agent are required to deduct and withhold under the Code, or any Legal Requirement, with respect to the making of such payment. To the extent that amounts are so withheld by Parent, the Surviving Corporation or the Payment Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Company Shares or Company Options in respect of whom such deduction and withholding was made by Parent, the Surviving Corporation or the Payment Agent.

2.8 Appraisal Rights.

(a) Notwithstanding anything to the contrary contained in this Agreement, any Company Shares that constitute Appraisal Shares shall not be converted into or represent the right to receive payment in accordance with Section 2.5, and each holder of Appraisal Shares shall be entitled only to such rights with respect to such Appraisal Shares as may be granted to such holder pursuant to Section 262 of the DGCL. From and after the Effective Time, a holder of Appraisal Shares shall not have and shall not be entitled to exercise any of the voting rights or other rights of a stockholder of the Surviving Corporation.

(b) The Company: (i) shall give Parent prompt written notice of any demand by any stockholder of the Company for appraisal of such stockholder’s Company Shares pursuant to Section 262 of the DGCL; and (ii) shall give Parent the opportunity to participate in all negotiations and proceedings with respect to any such demand. Except with the prior written consent of Purchaser (which consent may be withheld in the sole and absolute discretion of Purchaser) or as may otherwise be required by applicable Legal Requirements, the Company shall not make any payment with respect to, or settle or offer to settle, any such demands.

(c) For purposes of this Agreement, “Appraisal Shares” shall refer to any Company Shares outstanding immediately prior to the Effective Time that are held by stockholders who have preserved their appraisal rights under Section 262 of the DGCL with respect to such Company Shares. If any holder of Appraisal Shares shall fail to perfect or shall otherwise lose such holder’s right of appraisal under Section 262 of the DGCL, then: (i) any right of such holder with respect to such Company Shares as may be granted to such holder pursuant to Section 262 of the DGCL shall be extinguished; and (ii) such Appraisal Shares shall automatically be converted into and shall represent only the right to receive (upon the surrender of the Company Stock Certificate(s) representing such Appraisal Shares) payment for such Appraisal Shares in accordance with Section 2.5.

2.9 Further Action. If, at any time after the Effective Time, any further action is necessary to carry out the purposes of this Agreement, the officers and directors of the Surviving Corporation and Parent shall be authorized (in the name of Purchaser, in the name of the Company or otherwise) take such action.

(c) Each Company Plan complies in all material respects in form and operation, and has been administered in all material respects in accordance with, its terms and all applicable Legal Requirements, including ERISA and the Code, and all contributions required to be made under the terms of any of the Company Plans as of the date of this Agreement have been timely made or, if not yet due, have been properly reflected on the most recent consolidated balance sheet filed or incorporated by reference in the Company financial statements prior to the date of this Agreement. With respect to each Company Plan, all Tax, annual reporting and other filings with a Governmental Entity required by ERISA and the Code have been timely filed with the appropriate Governmental Entity and all notices and disclosures have been timely provided to participants. With respect to the Company Plans, no event has occurred and, to the knowledge of Company, there exists no condition or set of circumstances in connection with which the Company or any Company Subsidiary could be subject to any material liability (other than for routine benefit liabilities) under the terms of, or with respect to, such Company Plans, ERISA, the Code or any other applicable Legal Requirement.

(d) To the Company’s knowledge, there has been no prohibited transaction (within the meaning of Section 406 of ERISA or Section 4975 of the Code and other than a transaction that is exempt under a statutory or administrative exemption) with respect to any Company Plan that could result in liability to the Company or any ERISA Affiliate. Each Company Plan can be amended, terminated or otherwise discontinued after the Effective Time in accordance with its terms, without liability (other than (A) liability for ordinary administrative expenses typically incurred in a termination event or (B) if the Company Plan is a pension benefit plan subject to Part 2 of Title I of ERISA, liability for the accrued benefits as of the date of such termination (if and to the extent required by ERISA) to the extent that either there are sufficient assets set aside in a trust or insurance contract to satisfy such liability or such liability

Neither the Company, nor to the knowledge of the Company, any other Person or Entity has any express or implied commitment, whether legally enforceable or not, to modify, change or terminate any Company Plan, other than with respect to a modification, change or termination required by ERISA or the Code. No Legal Proceeding has been brought, or to the knowledge of Company is threatened, against or with respect to any such Company Plan, including any audit or inquiry by the IRS or United States Department of Labor. Neither the Company nor any ERISA Affiliate has any liability under ERISA Section 502. All contributions and payments to such Company Plan are deductible under Code Sections 162 or 404.

No amount that could be received (whether in cash, property, the vesting of property or otherwise) as a result of or in connection with the consummation of the transactions contemplated by this Agreement (either alone or in combination with any other event) or by any of the ancillary agreements, by any employee, officer, director or other service provider of the Company or any of the Company Subsidiaries who is a “disqualified individual” (as such term is defined in proposed Treasury Regulation Section 1.280G-1) could be characterized as an “excess parachute payment” (as defined in Section 280G(b)(1) of the Code).

(g) Except as required by applicable Legal Requirements, no Company Plan provides any of the following retiree or post-employment benefits to any Person: medical, disability or life insurance benefits. No Company Plan is a voluntary employee benefit association under Section 501(a)(9) of the Code. The Company and each ERISA Affiliate is in compliance in all material respects with (i) the requirements of the applicable health care continuation and notice provisions of the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, and the regulations (including proposed regulations) thereunder and any similar state law and (ii) the applicable requirements of the Health Insurance Portability and Accountability Act of 1996, as amended, and the regulations (including the proposed regulations) thereunder.

appreciation right, will or may provide for the deferral of compensation subject to Section 409A of the Code, whether pursuant to the execution and delivery of this Agreement or the consummation of the transactions contemplated hereby (either alone or upon the occurrence of any additional or subsequent events) or otherwise. Each Company Plan that is a nonqualified deferred compensation plan subject to Section 409A of the Code has been operated and administered in good faith compliance with Section 409A of the Code from the period beginning January 1, 2005 and continuing through the date hereof. All stock options granted under the Company Option Plans have been granted in compliance with the terms of applicable Legal Requirements and the applicable Company Option Plans and have (or with respect to such options which have been exercised as of the date of this Agreement, had) a per share exercise price that is (or with respect to such options which have been exercised as of the date of this Agreement, was) at least equal to the fair market value of a share of the underlying stock as of the date the option was granted (determined in accordance with applicable Legal Requirements, including, to the extent applicable, Section 409A of the Code).

(i) The Company and each of the Company Subsidiaries have properly classified all individuals providing services to the Company or any of the Company Subsidiaries as employees or non-employees for all relevant purposes.

(k) The execution and delivery of this Agreement and the consummation of the Offer and the Merger: (i) will not materially increase the benefits payable by the Company or any of the Company Subsidiaries under any Company Plan; and (ii) will not result in any acceleration of the time of payment or vesting of any material benefits payable by the Company or any of the Company Subsidiaries under any Company Plan.

(l) The Company Board, at a meeting duly called and held or by a duly executed action by unanimous written consent, has determined that each of the members of the Compensation Committee of the Company Board (the “Compensation Committee”) are, and the Company represents and warrants that each of the members of the Compensation Committee are and at the Acceptance Time will be, “independent directors” as defined in Rule 4200(a)(15) of the Nasdaq Marketplace Rules and eligible to serve on the Compensation Committee under the Exchange Act and all applicable Marketplace Rules of the NASDAQ Global Select Market. On or prior to the date hereof, the Compensation Committee, at a meeting duly called and held or by a duly executed action by unanimous written consent, approved each Company Compensation Arrangement as an “employment compensation, severance or other employee benefit

arrangement” within the meaning of Rule 14d-10(d)(1) under the Exchange Act (an “Employment Compensation Arrangement”), and has taken all other action necessary to satisfy the requirements of the non-exclusive safe harbor with respect to such Company Compensation Arrangements in accordance with Rule 14d-10(d)(2) under the Exchange Act.

There are no Legal Proceedings pending, or, to the knowledge of the Company, threatened, against the Company or any of the Company Subsidiaries with respect to employment, immigration, occupational health and safety, or wages and hours and that would reasonably be expected to have a Company Material Adverse Effect. Except as set forth in Part 3.22(b) of the Company Disclosure Schedule, neither the Company nor any of the Company Subsidiaries is a party to or bound by any Contract limiting the right of the Company to terminate the employment of any of its Executives at will or requiring the payment of severance upon termination.

Except as set forth in Part 3.22(d) of the Company Disclosure Schedule, there are no Legal Proceedings pending or, to the knowledge of the Company, threatened, between the Company or any of the Company Subsidiaries and any of their respective current or former employees, which Legal Proceedings would reasonably be expected to have a Company Material Adverse Effect, individually or collectively.

3.23 Environmental Matters. The Company and the Company Subsidiaries are in material compliance with all applicable Environmental Laws. Since January 1, 2003, neither the Company nor any of the Company Subsidiaries received any written notice from a Governmental Entity or third party that alleged that the Company or any of the Company Subsidiaries was materially violating any Environmental Law. To the knowledge of the Company, no current or prior owner of any property leased or controlled by the Company or any of the Company Subsidiaries received any written notice from a Governmental Entity or third party since January 1, 2003 that alleged that such current or prior owner or the Company or any of the Company Subsidiaries was materially violating any Environmental Law.

To the knowledge of the Company, there are no above-ground storage tanks on, under or about any property currently or previously owned or leased by the Company, the presence of which would reasonably be expected to have a Company Material Adverse Effect. True and correct summaries of all environmental audits or assessments which have been conducted by or on behalf of the Company at any Owned Real Property or Leased Real Property, have been delivered to Parent or Purchaser.

(For purposes of this Section 3.23, “Environmental Laws” shall mean any and all applicable international, federal, state, or local laws, statutes, ordinances, regulations, policies, guidance, rules, judgments, orders, court decisions or rule of common law, permits, restrictions and licenses, which (i) regulate or relate to the protection or clean up of the environment; the use, treatment, storage, transportation, handling, disposal or release of Hazardous Substances, the preservation or protection of waterways, groundwater, drinking water, air, wildlife, plants or other natural resources; or the health and safety of persons or property, including protection of the health and safety of employees; or (ii) impose liability or responsibility with respect to any of the foregoing, including the Comprehensive Environmental Response, Compensation and Liability Act (42 U.S.C. § 9601 et seq.), or any other Legal Requirement of similar effect. “Environmental Permits” shall mean any material permit, license, authorization or approval required under applicable Environmental Laws. “Hazardous Substances” shall mean any pollutant, chemical, substance and any toxic, infectious, carcinogenic, reactive, corrosive, ignitable or flammable chemical, or chemical compound, or hazardous substance, material or waste, whether solid, liquid or gas, that is subject to regulation, control or remediation under any Environmental Laws, including any quantity of asbestos in any form, urea formaldehyde, PCBs, radon gas, crude oil or any fraction thereof, all forms of natural gas, petroleum products or by-products or derivatives.)

All such policies are in full force and effect, all premiums due and payable have been paid, and since January 1, 2005, the Company has not received any written communication notifying the Company of any: (a) cancellation or invalidation of any material insurance policy held by the Company (except with respect to policies that have been replaced with similar policies); (b) refusal of any coverage or rejection of any material claim under any material insurance policy held by the Company; or (c) material adjustment in the amount of the premiums payable with respect to any insurance policy held by the Company. There is no pending material claim by the Company under any insurance policy held by the Company. Neither the Company nor any Company Subsidiary is in material breach or default, and neither the Company nor any Company Subsidiary has taken any action or failed to take any action which, with notice or the lapse of time, would constitute such a breach or default, or permit termination or material modification of any of the insurance policies. The consummation of the transactions contemplated by this Agreement will not, in and of itself, cause the revocation, cancellation or termination of any such insurance policies.

SECTION 4. REPRESENTATIONS AND WARRANTIES OF PARENT AND PURCHASER

Parent and Purchaser hereby jointly and severally represent and warrant to the Company that:

4.1 Due Organization. Each of Parent and Purchaser is a corporation duly organized, validly existing and in good standing under the laws of Delaware and has all requisite corporate power and authority necessary to carry on its business as it is now being conducted except where the failure to be so organized, existing or in good standing, individually or in the aggregate, would not be reasonably likely to prevent or materially delay the consummation of any of the transactions contemplated herein. Since its date of incorporation, Purchaser has not carried on any business or conducted any operations other than the execution of this Agreement, the performance of its obligations hereunder and matters ancillary thereto.

4.2 Authority; Binding Nature of Agreement. Parent has the requisite corporate power and authority to enter into and to perform its obligations under this Agreement. The board of directors of Parent, at a meeting duly called and held, has authorized and approved the execution, delivery and performance of this Agreement by Parent. The execution and delivery of this Agreement by Parent and the consummation by Parent of the transactions contemplated by this Agreement have been duly authorized by all necessary corporate action on the part of Parent, and no other corporate proceedings on the part of Parent are necessary to authorize this Agreement. This Agreement has been duly and validly executed and delivered by Parent and, assuming the due authorization, execution and delivery of this Agreement by the Company, constitutes the valid and binding obligation of Parent, enforceable against Parent in accordance with its terms, subject to: (i) laws of general application relating to bankruptcy, insolvency and the relief of debtors; and (ii) rules of law governing specific performance, injunctive relief and other equitable remedies. Purchaser is a newly formed, wholly-owned Subsidiary of Parent and has the requisite corporate power and authority to enter into and to perform its obligations under this Agreement. The board of directors of Purchaser has authorized and approved the execution, delivery and performance of this Agreement by Purchaser. The execution and delivery of this

Agreement by Purchaser and the consummation by Purchaser of the transactions contemplated by this Agreement have been duly authorized by all necessary corporate action on the part of Purchaser, and no other corporate proceedings on the part of Purchaser are necessary to authorize this Agreement other than, with respect to the Merger, the filing of the appropriate merger documents as required by the DGCL. Parent, as the sole stockholder of Purchaser, will vote to adopt this Agreement immediately after the execution and delivery of this Agreement. This Agreement has been duly executed and delivered by Purchaser and, assuming the due authorization, execution and delivery of this Agreement by the Company, constitutes the valid and binding obligation of Purchaser, enforceable against Purchaser in accordance with its terms, subject to: (1) laws of general application relating to bankruptcy, insolvency and the relief of debtors; and (2) rules of law governing specific performance, injunctive relief and other equitable remedies.

4.3 Non-Contravention; Consents. The execution and delivery of this Agreement by Parent and Purchaser, and the consummation by Parent or Purchaser of the Offer, the Merger and the other transactions contemplated by this Agreement, will not: (a) cause a violation of any of the provisions of the certificate of incorporation or bylaws of Parent or Purchaser; or (b) cause a violation by Parent or Purchaser of any Legal Requirement applicable to Parent or Purchaser; except in the case of clause (b) as would not be reasonably likely to prevent or materially delay the consummation of any of the transactions contemplated herein. Except as may be required by the Securities Act, the Exchange Act, the DGCL, the HSR Act or the antitrust or competition laws of foreign jurisdictions, Parent is not required to make any filing with or to obtain any consent from any Person in connection with the execution and delivery of this Agreement by Parent or Purchaser or the consummation by Parent or Purchaser of any of the transactions contemplated by this Agreement, except where the failure to make any such filing or obtain any such consent would not be reasonably likely to prevent or materially delay the consummation of any of the transactions contemplated herein. No vote of Parent’s stockholders is necessary to adopt this Agreement or to approve any of the transactions contemplated by this Agreement.

4.4 Not an Interested Stockholder. Neither Parent nor any of its Affiliates is an “interested stockholder” (as such term is defined in Section 203 of DGCL) of the Company.

4.5 Financing. Parent has available cash resources and financing in an amount sufficient to enable Purchaser to purchase Company Shares pursuant to the Offer and to consummate the Merger. Without limiting the foregoing: (a) Purchaser has delivered to the Company a true and complete copy of an executed commitment letter dated March 24, 2007 from ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ Senior Funding, Inc. and CitiGroup Global Market, Inc. (the “Debt Commitment Letter”), pursuant to which the lender parties thereto have committed, subject to the terms and conditions thereof, to lend the amounts set forth therein for the purpose of funding the consideration payable by Parent and the Purchaser in respect of the Company Shares and Company Options (the “Debt Financing”). As of the date of this Agreement: (i) the Debt Commitment Letter has not been amended or modified; and (ii) none of the commitments contained in the Debt Commitment Letter has been withdrawn or rescinded in any respect. There are no conditions precedent or other contingencies related to the funding by such lenders of the full amount of the Debt Financing, other than as set forth in or contemplated by the Debt Commitment Letter. As of the date of this Agreement, and assuming the accuracy of the Company’s representations set forth in this Agreement and the Company’s compliance with its

covenants set forth in this Agreement, in each case such that the conditions to the Debt Financing contemplated by the Debt Commitment Letter are satisfied, neither Parent nor Purchaser has any reason to believe that it will be unable to satisfy on a timely basis any term or condition to be satisfied by it contained in the Debt Commitment Letter. Parent or Purchaser will fully pay any and all commitment fees that are incurred and are due and payable in connection with the Debt Financing as and when they become payable.

4.6 Ownership of Company Shares. Neither Parent nor any of Parent’s Affiliates directly or indirectly owns, and at all times since January 1, 2005 neither Parent nor any of Parent’s Affiliates directly or indirectly has owned, beneficially or otherwise, any Company Shares or any securities, contracts or obligations convertible into or exercisable or exchangeable for Company Shares.

4.8 Information in Schedule 14D-9 and Proxy Statement. None of the written information supplied or to be supplied by or on behalf of Parent expressly for inclusion in the Schedule 14D-9 will, at the time the Schedule 14D-9 is mailed to the stockholders of the Company, or at any other time at or prior to the Acceptance Time, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they are made, not misleading.

licensee, partner or other Person to the extent necessary to facilitate any business dealings between the Company and such actual or potential customer, supplier, distributor, licensor, licensee, partner or other Person that are unrelated to any Acquisition Proposal or any Acquisition Inquiry and are not prohibited by the terms of Section 5.1, or (B) a Governmental Entity); (iii) participate or engage in discussions or negotiations with any Person with respect to an Acquisition Proposal or Acquisition Inquiry (for avoidance of doubt, it being understood that the foregoing shall not prohibit the Company or any of its advisors or representatives from making such Person aware of the restrictions of this Section 5.2 in response to the receipt of an Acquisition Proposal, nor shall it prohibit the Company from engaging in discussions with its advisors or representatives to the extent reasonably necessary to assist the Company in determining how to properly respond to such Acquisition Proposal or Acquisition Inquiry); or (iv) except as permitted pursuant to Section 5.3, approve, endorse or recommend to the Company’s stockholders any Acquisition Proposal; provided, however, that notwithstanding anything to the contrary contained in this Agreement, at any time prior to the Acceptance Time, the Company may, directly or indirectly through its Representatives, (A) engage or participate in discussions or negotiations with any Person (and may engage or participate in discussions or negotiations with such Person’s Representatives and potential financing sources) that has (1) made a bona fide Acquisition Proposal in writing that the Company Board determines in good faith After Consultation constitutes or is reasonably likely to lead to a Superior Proposal and (2) to the extent the Company is prohibited from disclosing such discussions or negotiations or the information exchanged in connection therewith, provided the Company with written acknowledgement that such discussions or negotiations and the information exchanged in connection therewith will be disclosed to Parent and its Representatives, and (B) furnish to any such Person described in clause (A) above (including to such Person’s Representatives and potential financing sources) any non-public information relating to the Company and its Subsidiaries pursuant to a confidentiality agreement (whether executed before or after the date of this Agreement), the terms of which are no less favorable in any material respect to the Company than those contained in the Confidentiality Agreement (provided that, for the avoidance of doubt such Confidentiality Agreement is not required to contain standstill provisions) (it being understood that none of the actions described in this proviso, shall, to the extent taken in accordance with this proviso, be prohibited by the preceding terms of this Section 5.2(a)); and provided further, that in the case of any action taken pursuant to clause (A) or clause (B) above, (1) the Company Board received such Acquisition Proposal other than as a result of a breach or violation of the terms of this Section 5.2, (2) the Company Board shall first have determined in good faith, After Consultation, that the failure to take such action does or would reasonably be likely to constitute a breach of its fiduciary obligations to the Company’s stockholders under applicable Legal Requirements; (3) at least 48 hours prior to initially engaging or participating in any such discussions or negotiations with, or initially furnishing any non-public information to, such Person, the Company gives Parent written notice of the identity of such Person and all of the material terms and conditions of such Acquisition Proposal and of the Company’s intention to engage or participate in discussions or negotiations with, or furnish non-public information to, such Person, and (4) contemporaneously with furnishing any non-public information to such Person, the Company furnishes such non-public information to Parent (to the extent such information has not been previously furnished by the Company to Parent). Without limiting the generality of the foregoing, the Company acknowledges and agrees that if any Company Subsidiary or Representative of the Company or Company Subsidiary (whether or not such Person is purporting to act on behalf of the Company) takes any action that, if taken by the Company, would constitute a breach of this Section 5.2(a) by the Company, then such action shall be deemed to constitute a breach of this Section 5.2(a) by the Company.

(b) In addition to the obligations of the Company set forth in Section 5.2(a) hereof, the Company shall promptly, and in all cases within one business day of its receipt, advise Parent orally (to be confirmed in writing as soon as practicable thereafter) of the receipt by the Company of any Acquisition Proposal or Acquisition Inquiry, including the material terms and conditions of such Acquisition Proposal or Acquisition Inquiry and the identity of the Person or group making any such Acquisition Proposal or Acquisition Inquiry. The Company shall keep Parent informed as promptly as practicable (and in any event within 24 hours) of any material change in the status of or material change in the proposed terms and conditions of (including all material amendments or proposed material amendments to), any such Acquisition Proposal or Acquisition Inquiry.

(c) Upon the execution and delivery of this Agreement, the Company shall immediately cease and cause to be terminated any existing discussions with any Person that relate to any Acquisition Proposal or Acquisition Inquiry.

(d) Unless the Company Board shall first have determined in good faith, After Consultation, that the failure to take the following actions does or would reasonably be likely to constitute a breach of its fiduciary obligations to the Company’s stockholders under applicable Legal Requirements, the Company (i) agrees not to release or permit the release of any Person from, or to waive or permit the waiver of any provision of, any confidentiality, standstill or similar agreement to which the Company is a party or under which the Company has any rights and (ii) will use its best efforts to enforce or cause to be enforced each such agreement at the request of Parent; provided, however, that the expiration or termination of such agreement or provision of such agreement by its own terms shall not be considered to be a violation of the foregoing clause “(i)” or “(ii)” by the Company. The Company also shall promptly (but in no event later than five business days after the execution of this Agreement) request each Person that since January 1, 2005 has executed a confidentiality agreement in connection with its consideration of a possible Acquisition Transaction or equity investment in the Company to return (or destroy, to the extent permitted by the terms of the applicable confidentiality agreement) all confidential information heretofore furnished to such Person by or on behalf of Company, subject to the terms of the applicable confidentiality agreement.

Change in Recommendation of its intention to make a Company Change in Recommendation. Notwithstanding the foregoing, the Company shall not enter into any Contract (other than a confidentiality agreement as contemplated by Section 5.2(d)), with respect to a Superior Proposal unless this Agreement has been or concurrently is validly terminated by its terms pursuant to Section 7.1 and Parent has received, by wire transfer of immediately available funds, any amounts due to Parent pursuant to Section 7.3.

(d) Without limiting any rights or remedies of Parent or Purchaser set forth in this Agreement that might exist as a consequence of any such action, nothing in this Agreement shall prohibit the Company Board from (i) taking and disclosing to the Company’s stockholders a position contemplated by Rule 14e-2(a) promulgated under the Exchange Act or complying with the provisions of Rule 14d-9 promulgated under the Exchange Act or (ii) making any disclosures to the Company’s stockholders that the Company Board determines in good faith After Consultation that the Company Board is required to make in order to comply with its fiduciary duties to the Company’s stockholders under Delaware Law.

It is the intention of the parties that, to the extent possible under the circumstances, each Assumed Option shall qualify following the Effective Time as an incentive stock option as defined in Section 422 of the Code to the extent such Assumed Option qualified as an incentive stock option prior to the Effective Time, provided that the parties acknowledge and agree that Assumed Options will not qualify under Section 422 of the Code if the Parent Share Price at the Effective Time is less than the Parent Share Price on the date hereof.

(b) Notwithstanding anything to the contrary in Section 5.9(a) above, in the event that the conversion of a Company Option as set forth in Section 5.9(a) above would result in a per-share exercise price of the corresponding Assumed Option of less than three percent (3%) of the Parent Share Price at the Effective Time, then such Company Option shall be cancelled and terminated in exchange for a cash payment (without interest) equal to the aggregate excess, if any, of the Offer Price over the exercise price of such Company Option immediately prior to the Effective Time. The Company shall, prior to the Acceptance Time, take all action and give any notices necessary to effect the treatment of the Company Options contemplated by this Section 5.9(b), including ensuring that the Compensation Committee has duly approved the accelerated vesting and cash settlement of such Company Options as an Employment Compensation Arrangement.

(c) The Company shall amend the Company ESPP, as necessary, (i) to provide that prior to the Effective Time, outstanding purchase rights under the Company ESPP shall be exercised in accordance with the terms of the Company ESPP and each Company Share purchased pursuant to such exercise shall by virtue of the Merger, and without any action on the part of the holder thereof, be converted into the right to receive the Merger Consideration, and (ii) to provide that, as and after the date hereof, no further offering periods or purchase periods shall commence.

(d) Parent shall file with the Securities and Exchange Commission, as soon as practicable, but in no event later than 10 business days, following the Effective Time, a registration statement on Form S-8 with respect to Parent Shares issuable under any Assumed Options issued under this Section 5.9 and shall use commercially reasonable efforts to maintain the effectiveness of such registration statement for as long as there are any Parent Shares issuable thereunder.

5.10 Other Employee Benefits.

(a) Following the Effective Time, any employee who as of the Effective Time is employed by the Company and the Company Subsidiaries (referred to herein individually as a “Continuing Employee” and collectively as the “Continuing Employees”) shall continue in the employment of the Parent, the Surviving Corporation or any Subsidiary of the Parent or Surviving Corporation after the Effective Time, provided, that to the extent such employment was “at-will” immediately prior to the Effective Time, such employment shall continue to be at-will and subject to termination at any time for any or no reason. Nothing in this Agreement shall be construed to create a right in any Continuing Employee to employment with Parent, the Surviving Corporation, or any of their respective Subsidiaries. For the period beginning on the Effective Time through the end of the calendar year in which the Effective Time occurs, Parent shall provide, or cause to be provided, to each Continuing Employee compensation and employee benefits under either the Company Plans or under employee benefit plans and programs of Parent, the Surviving Corporation or any Subsidiary of Parent or the Surviving Corporation (the “Parent Plans”), or under any combination of the Company Plans and the Parent Plans.

(b) With respect to any Parent Plans that provide group medical, dental, disability or prescription drug coverage in which any Continuing Employees become eligible to participate after the Effective Time, Parent shall, or shall cause the Surviving Corporation or their respective Subsidiaries to: (i) waive (to the extent such Parent Plan is self-insured), or use commercially reasonable efforts to waive (to the extent such Parent Plan is insured), any exclusions for pre-existing conditions under such Parent Plans that would result in a lack of coverage for any condition for which the applicable Continuing Employee would have been entitled to coverage under the corresponding Company Plan in which such Continuing Employee was an active participant immediately before his or her transfer to the Parent Plan; (ii) waive any coverage waiting periods under any such Parent Plans to the extent that such periods exceed the corresponding waiting period under the corresponding Company Plan in which any applicable Continuing Employee was an active participant immediately before his or her transfer to any such Parent Plans (after taking into account any prior service with the Company or its Subsidiaries credited under such Company Plan for purposes of satisfying such waiting period); (iii) provide each applicable Continuing Employee with credit for any co-payments deductibles and premiums for voluntary coverage paid by such Continuing Employee before his or her transfer to any such Parent Plans (to the same extent such credit was given under the analogous Company Plans before such transfer) in satisfying any applicable deductible, out-of-pocket requirements or coverage levels under any such Parent Plans for the plan year that includes such transfer; provided that, such Continuing Employee shall be responsible for any applicable co-payments or premiums for voluntary coverage required to be made under such Parent Plans, and (iv) provide each applicable Continuing Employee with credit for any unused account balance in each Company Plan that includes a flexible spending account before his or her transfer to any analogous Parent Plan for the plan year that includes such transfer.

(c) Following the Effective Time, Continuing Employees shall be eligible to participate in a qualified cash or deferred arrangement or arrangements under Section 401(k) of the Code sponsored by Parent or a Subsidiary of Parent for the benefit of their eligible employees, provided that Continuing Employees shall not be entitled to receive credit for past

service with the Company or its Subsidiaries for purposes of determining the amount of company contributions or vesting under any qualified defined contribution or defined benefit retirement plans sponsored or maintained by Parent, the Surviving Corporation, or their respective Subsidiaries. Without limiting the generality of the foregoing, Continuing Employees shall not be eligible to participate in any Parent Plans under which new Parent employees are not currently eligible to participate.

(d) Following the Effective Time, Continuing Employees shall receive credit for past service (calculated under the method applicable to Parent’s similarly-situated employees) with the Company and its Subsidiaries for purposes of eligibility to participate in the generally applicable severance plan currently maintained by Parent for its and its Subsidiaries’ employees, provided that Continuing Employees shall be required to enter into Parent’s standard release as a condition to the receipt of any benefits under Parent’s severance plan and shall not be entitled to receive the additional severance benefits under such plan otherwise provided in consideration for entering into a release. Continuing Employees covered by a Company Plan providing severance benefits following a change of control shall be covered by such Company Plan according to its terms, and following the period of coverage in such Company Plan, shall participate in the generally applicable severance plan currently maintained by Parent for its and its Subsidiaries’ employees according to the preceding sentence.

(e) Following the Effective Time, Continuing Employees shall be entitled to carryover or otherwise receive credit under any applicable Parent Plans they may participate in for any vacation days, sick days, or other paid time off that is accrued but unused at the Effective Time under the Company Plans. Vacation days, sick days, or other paid time off that is accrued but unused at the Effective Time under the Company Plans shall not be reduced as of the Effective Time, but accruals of Continuing Employees following the Effective Time may be limited to comply with the applicable policies and programs of Parent and its Subsidiaries.

(f) Except as specifically provided in this Section 5.10, Continuing Employees shall not receive credit for past service with the Company or its Subsidiaries for purposes of eligibility to participate in or receive benefits under any Parent Plans.

(g) Nothing contained in this Section 5.10: (i) shall be construed to establish, amend or modify any benefit plan, program, agreement or arrangement, (ii) shall alter or limit Parent’s ability to amend, modify or terminate any benefit plan, program, agreement or arrangement at any time assumed, established, sponsored or maintained by Parent, (iii) is intended to confer upon any current or former employee any right to employment or continued employment for any period of time by reason of this Agreement, or any right to a particular term or condition of employment, or (iv) is intended to confer upon any individual (including employees, retirees, or dependents or beneficiaries of employees or retirees) any right as a third-party beneficiary of this Agreement.

5.11 Indemnification; Directors’ and Officers’ Insurance.

(a) From and after the Acceptance Time, Parent will cause the Surviving Corporation to honor in all respects the obligations of the Company and the Company Subsidiaries pursuant to (i) each indemnification agreement in effect on the date of this

Agreement between the Company or any of the Company Subsidiaries and any Indemnified Party; and (ii) any indemnification provision and any exculpation provision in favor of an Indemnified Party that is set forth in the certificate of incorporation or bylaws of the Company and the equivalent organizational documents of any Company Subsidiary in effect as of the date of this Agreement.

(b) Through the sixth anniversary of the Effective Time, Parent will cause Surviving Corporation to be maintain in effect, for the benefit of the Company’s directors and officers that are insured under the Company’s current directors’ and officers’ liability insurance policy in effect as of the date of this Agreement (the “D&O Insurance Policy”), the current level and scope of directors’ and officers’ liability insurance coverage as set forth in the D&O Insurance Policy; provided, however, that in no event shall the Surviving Corporation be required pursuant to this Section 5.11(b) to expend an aggregate amount in excess of 200% of the annual premium currently payable by the Company with respect to such current D&O Insurance Policy, it being understood that if the annual premiums payable for such insurance coverage exceed such amount, the Surviving Corporation shall be obligated to obtain a policy with the greatest coverage available for a cost equal to such amount. At any time prior to the Effective Time, notwithstanding anything to the contrary set forth in this Agreement, the Company may purchase, and shall purchase at the request of Parent, a “tail” prepaid policy on the D&O Insurance Policy covering a period of six years from the Effective Time; provided that the aggregate amount of such “tail” policy is less than 200% of the annual premium currently payable by the Company with respect to its current D&O Insurance Policy. In the event that the Company shall purchase such a “tail” policy prior to the Effective Time, Parent will cause the Surviving Corporation to maintain such “tail” policy in full force and effect and continue to honor its respective obligations thereunder, in lieu of all other obligations of Parent under the first sentence of this Section 5.11(b) for so long as such “tail” policy shall be maintained in full force and effect.

(c) This Section 5.11 shall survive the Acceptance Time and shall also survive consummation of the Merger and the Effective Time. This Section 5.11 is intended to benefit, and may be enforced by, the Indemnified Parties and their respective heirs, representatives, successors and assigns, and shall be binding on all successors and assigns of the Surviving Corporation. In the event of any merger, consolidation or other similar transaction involving the Surviving Corporation, or in the event of any sale by the Surviving Corporation of all or substantially all of its assets, the Surviving Corporation shall ensure that an Entity no less financially viable than the Surviving Corporation remains responsible for the obligations of the Surviving Corporation under this Section 5.11.

(d) For purposes of this Agreement, each individual who is an officer or director of the Company at the date of this Agreement or was an officer or director of the Company within the six years prior to the date of this Agreement shall be deemed to be an “Indemnified Party.”

5.12 Section 16 Matters. Prior to the Effective Time, Parent and the Company shall take all such steps as may be required to cause any dispositions of Company Shares (including derivative securities with respect to Company Shares) resulting from the Merger by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company or will become subject to such reporting requirements with respect to Parent, to be exempt under Rule 16b-3 promulgated under the Exchange Act.

5.13 Rule 14d-10(d). Prior to the Acceptance Time, the Company (acting through its Compensation Committee) will take all such steps as may be required to cause each agreement, arrangement or understanding entered into by the Company or the Company Subsidiaries on or after the date hereof with any of its officers, directors or employees pursuant to which consideration is paid to such officer, director or employee to be approved as an Employment Compensation Arrangement and to satisfy the requirements of the non-exclusive safe harbor set forth in Rule 14d-10(d) of the Exchange Act.

5.14 Cooperation Regarding Transition of Business. After the Acceptance Time, if requested by Parent, the Company will take commercially reasonable action to cooperate with Parent in the planning and preparation of the integration of the Company’s and Parent’s business, including with respect to the matters identified in Part 5.14 of the Company Disclosure Schedule following the Acceptance Time. Nothing in this Section 5.14 will require the Company to take any action in violation of Legal Requirements.

5.15 Termination of Certain Company Plans. At the request of Parent and prior to the Acceptance Time, the Company will take all necessary corporate actions to approve and effect the termination of any and all Company Plans intended to qualify as a qualified cash or deferred arrangement under Section 401(k) of the Code effective immediately preceding the Acceptance Time (provided that such termination shall not cause the Continuing Employees to fail to be covered by a qualified cash or deferred arrangement under Section 401(k) of the Code). Following the Effective Time, Parent shall use commercially reasonable efforts to cause the Company to continue in effect the Company’s Nonqualified Deferred Compensation Plan, 409A Nonqualified Deferred Compensation Plan, Director Fee Deferral Program under the Amended and Restated 1996 Stock Incentive Plan, provided that, Parent may elect to cause the Company to terminate participant’s ability to make future contributions under such plans. At the request of Parent and prior to the Acceptance Time, the Company shall take all necessary corporate action to approve and effect the termination of any substantially similar deferred compensation arrangements within the meaning of Section 409A of the Code effective immediately preceding the Acceptance Time, and the payment of all amounts deferred under such plans (including payment in respect of any stock units granted under the Amended and Restated 1996 Stock Incentive Plan) as soon as practicable following the Effective Time and in any event within 12 months of the Acceptance Time. The Company will provide Parent with evidence that any such plans terminated pursuant to this Section 5.15 have been so terminated pursuant to resolutions duly adopted by the Company Board or other duly-designated authority.

5.16 Financing.

(a) Parent and the Purchaser shall use their commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to arrange and obtain the Debt Financing on the terms and conditions described in the Debt Commitment Letter, including using commercially reasonable efforts to (a) maintain in effect the Debt Commitment Letter and negotiate and enter into definitive agreements with respect to the Debt Financing on the terms and conditions reflected in the Debt Commitment

Letter or on other terms reasonably acceptable to Parent and the Purchaser, (b) satisfy on a timely basis all material conditions applicable to Parent and the Purchaser in such definitive agreements that are within their control, (c) consummate the Debt Financing at such time or from time to time as is necessary for Purchaser to satisfy its obligations under this Agreement (d) enforce its rights under the Debt Commitment Letter; provided, however, that Parent or Purchaser shall have the right to substitute alternative financing for the Debt Commitment Letter with a different letter or a letter from alternative lenders so long as such substitute letter is subject to financing conditions that are at least as favorable to Parent and Purchaser as the financing conditions set forth in the Debt Commitment Letter. In the event any portion of the Debt Financing becomes unavailable on the terms and conditions contemplated in the Debt Commitment Letter for any reason, Parent and the Purchaser shall use their commercially reasonable efforts to obtain alternative financing on terms no less favorable to Purchaser than the Debt Financing from alternative sources (“Alternative Financing”) as promptly as practicable following the occurrence of such event. For the avoidance of doubt, Parent’s and the Purchaser’s obligation to consummate the Offer, the Merger and the other transactions contemplated by this Agreement are not (and shall not be) subject to any financing condition.

(b) In the period between the date of this Agreement and the Effective Time, upon request of Parent, the Company shall, and shall use commercially reasonable efforts to cause its Subsidiaries, and its and their Affiliates and Representatives to, reasonably cooperate with Parent in connection with its financing of the transactions contemplated in this Agreement, including using commercially reasonable efforts to (i) participate in meetings and road shows, if any; (ii) provide information reasonably requested by Parent relating to such financing; (iii) assist in the preparation of offering memoranda, private placement memoranda, prospectuses and similar documents of Parent; and (iv) obtain the consent of, and customary comfort letters from, Ernst & Young, LLP (including by providing customary management letters and requesting legal letters to obtain such consent) if necessary or desirable for Parent’s use of the Company’s financial statements. Parent shall promptly, upon request by the Company, reimburse the Company for all documented out-of-pocket expenses incurred by the Company or its Affiliates or Representatives in connection with such cooperation.

5.17 Tax Matters. Upon Parent’s request, the Company shall promptly deliver or make available to Parent complete and accurate copies of all Tax Returns of the Company and each Company Subsidiary and complete and accurate copies of all examination reports and statements of deficiencies assessed against or agreed to by the Company, any Company Subsidiary or any of their predecessors since its last open Tax year.

6.4 Offers Purchased. Purchaser shall have purchased the Company Shares pursuant to the Offer (provided that this shall not be a condition to Parent’s and Purchaser’s obligations if Purchaser shall have failed to purchase or exchange such Company Shares in violation of this Agreement, notwithstanding the satisfaction or waiver by Purchaser of all of the conditions to the Offer set forth in Annex I attached).
