ARTICLE 3

Manner of Converting Securities

3.1 Conversion of Capital Stock. Subject to the provisions of this Article 3, at the Effective Time, by virtue of the Merger and without any action on the part of the holders of the shares of Common

2

Stock or the holders of shares of common stock, $0.01 par value per share, of the Purchaser (“Purchaser Common Stock”):

(a) Purchaser Common Stock. Each share of the Purchaser Common Stock issued and outstanding immediately prior to the Effective Time shall be converted automatically into and become one validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation. Each certificate evidencing ownership of the Purchaser Common Stock immediately prior to the Effective Time shall, as of the Effective Time, evidence ownership of such shares of the Surviving Corporation.

(b) Parent Common Stock. Each issued and outstanding share of common stock, no par value per share, of the Parent will remain issued and outstanding.

(c) Conversion of Common Stock. Each outstanding share (including any Restricted Shares) of Common Stock (other than shares of Common Stock to be cancelled in accordance with Section 3.2 and other than Dissenting Common Stock) shall cease to be outstanding and shall be converted automatically into, and represent the right to receive the Merger Consideration, payable to the holder thereof in cash, without interest. From and after the Effective Time, all such shares of Common Stock shall no longer remain outstanding and shall automatically be cancelled and retired, and each holder of a certificate representing any such shares of Common Stock shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration therefor upon the surrender of such certificate in accordance with Section 3.6, without interest thereon.

3.2 Cancellation of Treasury Stock and Parent-Owned Stock. All shares of Common Stock that are owned by the Company as treasury stock and any shares of Common Stock owned by the Parent, the Purchaser or any other wholly-owned Subsidiary of the Parent shall be cancelled and retired, and no consideration shall be delivered in exchange therefor.

3.3 Adjustments to Merger Consideration. If, between the date of this Agreement and the Effective Time, the Company changes the number of shares of Common Stock issued and outstanding prior to the Effective Time as the result of any stock split, reverse split, stock dividend (including any dividend or distribution of securities convertible into Common Stock), reclassification, reorganization, recapitalization or other like change with respect to Common Stock (each, an “Adjustment”), the Merger Consideration shall be adjusted accordingly, without duplication, to provide the holders of shares of Common Stock with the same economic effect as contemplated by this Agreement prior to such Adjustment.

3.4 Derivative Securities.

(a) The Board of Directors of the Company shall take all actions necessary to cause, at the Effective Time, each outstanding option, stock equivalent right or other right to acquire shares of Common Stock (an “Option” or “Options”) granted under the Option Plans whether or not then exercisable or vested, except as set forth on Section 3.4(a) of the Company Disclosure Schedule, to be 100% exercisable and vested and to be cancelled and, in consideration of such cancellation, at the Effective Time the Parent shall, or shall cause the Surviving Corporation to, pay to such holders of Options, an amount in respect thereof equal to the product of (x) the excess, if any, of the Merger Consideration over the exercise price of each such Option and (y) the number of shares of Common Stock subject to such Option (such payment, if any, to be net of applicable withholding and excise taxes). As of the Effective Time, all Option Plans and any agreement or plan relating to Options shall terminate and all rights under any provision of any other plan, program or arrangement providing for the issuance or grant of any other interest in respect to the capital stock of the Company or any Company Subsidiary, including

3

the RSUs, shall be cancelled. The Company shall use its commercially reasonable efforts to effectuate the foregoing, including, but not limited to, obtaining all consents necessary to cash out and cancel all Options and as are necessary to ensure that, after the Effective Time, no Person shall have any right under any of the Option Plans, or any other plan, program or arrangement with respect to equity securities of the Surviving Corporation or any subsidiary thereof.

(b) (i) Immediately prior to the Effective Time, each restricted stock unit (“RSU”) issued by the Company under its Option Plans that is outstanding as of the date of this Agreement, whether or not vested and subject to conversion into Common Stock under its Option Plans, shall be converted automatically into one share of Common Stock and shall be entitled only to receive the Merger Consideration, and (ii) each restricted share of Common Stock issued by the Company pursuant to any applicable restricted stock award agreement of the Company and subject to any vesting, repurchase or other lapse restrictions thereunder (each, a “Restricted Share”) that is outstanding as of the date of this Agreement, whether or not vested or subject to repurchase, shall automatically vest and become free of such restrictions and right of repurchase as of the Effective Time and shall, as of the Effective Time, be cancelled and converted into the right to receive the Merger Consideration.

(c) The Board of Directors of the Company shall take all action necessary to cause (i) any “Offering Periods” (as defined in the 1998 Employee Stock Purchase Plan, as amended (the “ESPP”)) then in progress to be shortened by setting a new “Exercise Date” (as defined in the ESPP) as of a date prior to the Effective Time, and any Offering Periods then in progress shall end on such new Exercise Date, and (ii) the termination of the ESPP effective as of a time following such new Exercise Date but at or prior to the Effective Time of the Merger, as may be requested by the Parent.

3.5 Dissenting Common Stock.

(a) Notwithstanding anything in this Agreement to the contrary, Common Stock outstanding immediately prior to the Effective Time which is held by a holder who has not voted in favor of the Merger or consented thereto in writing and who has complied with Section 262 of the DGCL (“Dissenting Common Stock”) shall not be converted into the right to receive the Merger Consideration, unless such holder fails to perfect or withdraws or otherwise loses its right to appraisal. A holder of Dissenting Common Stock shall be entitled to receive payment of the appraised value of the Common Stock held by it in accordance with Section 262 of the DGCL, unless, after the Effective Time, such holder fails to perfect or withdraws or loses its right to appraisal, in which case such Common Stock shall be converted into and represent only the right to receive the Merger Consideration, without interest thereon, upon surrender of the Certificate or Certificates representing such Common Stock pursuant to Section 3.6.

(b) The Company shall give the Parent (i) prompt notice of any written demands for appraisal of any Common Stock received by the Company pursuant to Section 262 of DGCL, withdrawals of such demands, and any other instruments served pursuant to the DGCL and received by the Company relating to rights of appraisal and (ii) the opportunity to participate in the conduct of all negotiations and proceedings with respect to demands for appraisal under the DGCL. Except with the prior written consent of the Parent, the Company shall not voluntarily make any payment with respect to any demands for appraisal or settle or offer to settle any such demands for appraisal.

3.6 Exchange of Certificates.

(a) Paying Agent. Prior to the Effective Time, the Parent shall designate a national bank or trust company (which shall be reasonably acceptable to the Company) to act as agent for the holders of shares of Common Stock in connection with the Merger (the “Paying Agent”) and to receive

4

the funds to which holders of shares of Common shall become entitled pursuant to Section 3.1(c). At or prior to the Effective Time, the Parent or the Purchaser shall deposit or cause to be deposited with the Paying Agent, for exchange, in accordance with this Section 3.6, and payment, in accordance with Section 3.4, an amount of cash sufficient to make payment of the aggregate Merger Consideration (other than that for Dissenting Common Stock) and payments relating to Options and RSUs pursuant to this Agreement (such deposited Merger Consideration and payments relating to Options and RSUs pursuant to this Agreement referred to herein as the “Exchange Fund”). In the event that a holder of Dissenting Common Stock effectively withdraws its dissenters rights under the DGCL following the Effective Time, such holder of Dissenting Common Stock shall properly surrender its Certificate(s) and following such surrender : (i) all of such shares of Dissenting Common Stock shall be cancelled and (ii) such holder of the Dissenting Common Stock surrendered shall receive payment therefor from the Purchaser or the Parent in an amount equal to the Merger Consideration per share of Dissenting Common Stock so cancelled. Notwithstanding the foregoing, such funds shall be invested by the Paying Agent as directed by the Parent or the Surviving Corporation, in its sole discretion, pending payment thereof by the Paying Agent to the holders of the Common Stock; provided, that such investments shall be in obligations of or guaranteed by the United States of America, in commercial paper obligations rated A-1 or P-1 or better by Xxxxx’x Investors Service, Inc. or Standard & Poor’s Corporation, respectively, or in certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding $1 billion (based on the most recent financial statements of such bank which are then publicly available). Earnings from such investments shall be the sole and exclusive property of the Parent and the Surviving Corporation, and no part of such earnings shall accrue to the benefit of holders of Common Stock.

(b) Exchange Procedures. Promptly after the Effective Time, but in no event more than five (5) Business Days, the Parent shall cause the Paying Agent to mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented issued and outstanding shares of Common Stock (the “Certificates”) whose shares were converted pursuant to Section 3.1 into the right to receive the Merger Consideration (i) a letter of transmittal in customary form, mutually agreed to by the Company and the Parent (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Paying Agent) and (ii) instructions for effecting the surrender of the Certificates in exchange for payment of the Merger Consideration. After the Effective Time, upon surrender of a Certificate for cancellation to the Paying Agent or to such other agent or agents as may be appointed by the Parent, together with such transmittal materials, properly and duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration for each share of Common Stock formerly represented by such Certificate or Certificates, and the Certificate or Certificates so surrendered shall forthwith be cancelled, and the holder of such Certificate shall be paid promptly in exchange therefor cash in an amount equal to the Merger Consideration that such holder has the right to receive pursuant to the provisions hereof. If payment of the Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate is registered, it shall be a condition precedent of payment that (x) the Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and (y) the Person requesting such payment shall have paid any transfer and other taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate surrendered or shall have established to the satisfaction of the Surviving Corporation that such tax either has been paid or is not required to be paid. Until surrendered as contemplated by this Section 3.6(b), neither the Parent nor the Purchaser shall be obligated to deliver the Merger Consideration to the holder of shares of Common Stock and, after the Effective Time, each Certificate shall be deemed after the Effective Time to represent only the right to receive the Merger Consideration, without interest thereon.

(c) Lost, Stolen, or Destroyed Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit (in a form reasonably satisfactory to the Purchaser) of

5

that fact by the Person claiming such Certificate to be lost, stolen or destroyed, the Paying Agent will issue, in each case, in exchange for such affidavit, the appropriate amount of Merger Consideration deliverable in respect thereof as determined in accordance with Section 3.1; provided that the Person to whom the Merger Consideration is paid shall, as a condition precedent to the payment thereof, upon the request of the Purchaser, the Parent, or Surviving Corporation, indemnify the Surviving Corporation and the Parent in a manner reasonably satisfactory to them (by the posting by such Person of such bond and security as the Surviving Corporation and the Parent my reasonably request) against any claim that may be made against the Surviving Corporation and the Parent with respect to the Certificate claimed to have been lost, stolen or destroyed.

(d) Transfer Books; No Further Ownership Rights in Capital Stock. At the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of shares of Common Stock on the records of the Company. From and after the Effective Time, the holders of Certificates evidencing ownership of shares of Common Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such shares of Common Stock, except as otherwise provided for herein or by applicable Law. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be cancelled and exchanged as provided in this Article 3.

(e) Termination of Fund; No Liability. Subject to applicable Law, any portion of the Exchange Fund (including the proceeds of any investments thereof) which had been made available to the Paying Agent pursuant to Section 3.6 of this Agreement that remain unclaimed by the former stockholders of the Company for one year after the Effective Time shall be paid to the Parent. Any former stockholders of the Company who have not theretofore complied with this Article 3 shall thereafter look only to the Parent (subject to abandoned property, escheat or other similar laws) for payment of the Merger Consideration, without any interest thereon. Any other provision of this Agreement notwithstanding, none of the Parent, the Purchaser, the Company, the Surviving Corporation, or the Paying Agent shall be liable to a holder of the Common Stock for any amount paid or property delivered in good faith to a public official pursuant to any abandoned property, escheat, or similar Law. Any amounts remaining unclaimed by any holder of Common Stock immediately prior to the time when such amounts would otherwise escheat to or become the property of a federal, state, or local government authority or court or administrative or regulatory agency, shall, to the extent permitted by Law, become the property of the Parent, free and clear of all claims or interest of any Person previously entitled thereto.

(f) Withholding Taxes. Each of the Surviving Corporation, the Paying Agent, and the Parent shall be entitled to deduct and withhold from the Merger Consideration otherwise payable hereunder to any Person such amounts as it is required to deduct and withhold pursuant to any applicable Tax Laws. To the extent such amounts are deducted, withheld, and paid to the appropriate Governmental Entity, such deducted and withheld amounts shall be treated for all purposes of this Agreement as having been paid to such Person.

3.7 Subsequent Actions. If at any time after the Effective Time, the Surviving Corporation shall determine that any actions are necessary or desirable to vest, perfect or confirm of record or otherwise in the Surviving Corporation its right, title or interest in, to or under any of the rights, properties or assets of either of the Company or the Purchaser acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger or otherwise to carry out this Agreement, then the officers and directors of the Surviving Corporation shall be authorized to take all such actions as may be necessary or desirable to vest all right, title or interest in, to and under such rights, properties or assets in the Surviving Corporation or otherwise to carry out this Agreement.

The Company is duly qualified or licensed to do business as a foreign corporation and is in good standing in each jurisdiction where the character of the property owned or leased by it or the nature of its business makes such qualification necessary, except where the failure to be so qualified or licensed and in good standing would not, individually or in the aggregate, have a Material Adverse Effect on the Company.

Except for the approval of this Agreement and adoption of the Merger by the requisite holders of the issued and outstanding shares of Common Stock, no other corporate action is required on the part of the Company to authorize the consummation of the Transactions. This Agreement has been duly executed and delivered by the Company and, assuming due and valid authorization, execution, and delivery hereof by the Parent and the Purchaser, this Agreement is a valid and binding obligation of the Company enforceable against it in accordance with their respective terms (subject to applicable bankruptcy, insolvency, reorganization, moratorium, or similar Laws affecting creditors’ rights generally and except that the availability of the equitable remedy of specific performance and injunctive relief is subject to the discretion of the court before which any proceedings may be brought (the “Bankruptcy and Equity Exceptions”)).

(b) Notwithstanding Section 6.2(a) hereof, prior to receipt of the approval of the stockholders of the Company to this Agreement and the Merger, the Company may furnish, pursuant to a confidentiality agreement with terms no less favorable to the Company than those contained in the Confidentiality Agreement (subject to applicable Law, including without limitation the fiduciary obligations of the board of directors of the Company), information concerning its business, properties or assets and such other information as it deems relevant to any Person making an Acquisition Proposal that did not result from a breach of this Agreement and that the board of directors of the Company determines in good faith (after consultation with outside counsel and its financial advisors) could be reasonably expected to lead to a Superior Proposal, and may negotiate and participate in discussions and negotiations with such Person concerning such Acquisition Proposal if in the good faith opinion of the board of directors of the Company, after consultation with outside legal counsel to the Company, it is determined that providing such information or access or engaging in such discussions or negotiations is in the best interests of the Company and its stockholders and necessary in order for the board of directors of the Company to discharge its fiduciary duties to the Company’s stockholders under applicable Law. The Company shall notify the Parent of such determination relating to a potential Superior Proposal and shall promptly provide to the Parent any material non-public information regarding the Company provided to any other party, which was not previously provided to the Parent.

As used herein, the term “Superior Proposal” shall mean a bona fide, written Acquisition Proposal made by such entity or group on an unsolicited basis, and in the absence of any violation of this Section 6.2 by the Company, which the board of directors determines, in good faith after consultation with its legal and financial advisors, is (i) not subject to any condition related to financing or, if so subject, that the board of directors of the Company has determined in its good faith judgment that it is reasonably likely to be financed, (ii) reasonably likely to be consummated (taking into account the legal aspects of the Acquisition Proposal, the Person making the Acquisition Proposal and approvals required in connection therewith), and (iii) more favorable (taken as a whole) than the Merger Consideration to the Company's stockholders from a financial point of view; provided, that a Superior Proposal may be subject to customary conditions.

(c) Except as set forth in this Sections 6.2(c), neither the board of directors of the Company nor any committee thereof shall withdraw or modify, or propose to withdraw or modify, in a manner adverse to the Transactions, to the Parent or to the Purchaser, the approval or recommendation by the board of directors of the Company of this Agreement or the Merger, (ii) approve or recommend or propose to approve or recommend, any Acquisition Proposal, or (iii) enter into any agreement with respect to any Acquisition Proposal.

Notwithstanding the foregoing, prior to the earlier of the termination of this Agreement or the Effective Time, the board of directors of the Company may (subject to the terms of this and the following sentence) withhold, withdraw or modify its approval or recommendation of this Agreement and the Merger, approve or recommend a Superior Proposal, or enter into an agreement with respect to a Superior Proposal, in each case at any time after the third Business Day following the Company’s delivery to the Parent of a notice of its determination that an Acquisition Proposal constitutes a Superior Proposal (a “Superior Proposal Notice”); provided, however, that the Company shall not terminate this Agreement and enter into an agreement with respect to a Superior Proposal unless (i) prior to any such termination the Company has provided the Parent with a Superior Proposal Notice with respect to such Superior Proposal as aforesaid, (ii) within a period of three Business Days following the delivery of the Superior Proposal Notice, the Parent does not propose to amend this Agreement or enter into an

28

alternative transaction, in either case which the board of directors of the Company determines in its good faith judgment in consultation with its legal and financial advisors to be as favorable to the Company’s stockholders, from a financial point of view, as such Superior Proposal, and (iii) at least three full Business Days after the Company has provided the Superior Proposal Notice, the Company delivers to the Parent a written notice of termination of this Agreement pursuant to this Section 6.2(c) and payment of the Termination Fee in accordance with Section 9.2 of this Agreement.

6.3 SEC Reports. The Company shall file in a timely manner all reports, forms, filings, registration statements, and other documents (including, but not limited to, all exhibits, post-effective amendments and supplements thereto) required to be filed by it under the Exchange Act (including, but not limited to, any applicable reports on Form 8-K) between the date of this Agreement and the Effective Date. If financial statements are contained in any reports filed with the SEC, such financial statements will present fairly, in all material respects, the consolidated financial position of the entity filing such statements as of the dates indicated and the consolidated results of operations, changes in stockholders’ equity, and cash flows for the periods then-ended in accordance with GAAP (subject in the case of interim financial statements to normal recurring year-end adjustments and except for the permissible absence of footnote disclosure in unaudited financial statements). As of their respective dates, such reports filed with the SEC will comply as to form in all material respects with the Securities Act and the Exchange Act and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

7.7 Insurance and Indemnification.

(a) For a period of six years after the Effective Time, the Parent shall, or shall cause the Surviving Corporation (or any successor to the Surviving Corporation) to indemnify, defend and hold harmless the present and former directors and officers of the Company and of any Company Subsidiaries, and Persons who become any of the foregoing prior to the Effective Time (each an “Indemnified Party”) against all losses, claims, damages, liabilities, costs, fees and expenses (including reasonable fees and disbursements of counsel) and judgments, fines, losses, claims, liabilities and amounts paid in settlement incurred in connection with or arising out of any claim, action, suit, proceeding, or investigation, whether criminal, civil, administrative or investigative, arising out of any acts or omissions occurring at or prior to the Effective Time (including, without limitation, the Transactions); provided, however, that neither the Parent nor the Surviving Corporation shall be required to indemnify any Indemnified Party pursuant hereto if it shall be determined by a court of competent jurisdiction that the Indemnified Party acted in bad faith or, with respect to any criminal action or proceeding, that the Indemnified Party did not have reasonable cause to believe that its conduct was lawful, whether asserted or claimed prior to, at or after the Effective Time, to the fullest extent permitted under applicable Law. The Parent also shall advance expenses incurred promptly upon (but in any event with ten days following) receipt of statements therefor from any Indemnified Party; provided that the Person to whom such advances are made provides an

31

undertaking to repay such advances if it is ultimately determined by a court of competent jurisdiction that such Person is not entitled to indemnification. The Parent and the Company agree that in the event any claim, action, suit, proceeding, or investigation is asserted, commenced, or made within the six-year period contemplated by this Section 7.7, all rights to indemnification in respect of any such claim, action, suit, proceeding, or investigation shall continue until disposition of any and all such claims.

(b) The Parent agrees that all rights to indemnification and advancement of expenses existing in favor of, and all limitations on the personal liability of, the present or former directors or officers of the Company or any Company Subsidiary as provided in the Company’s Certificate of Incorporation or Bylaws, the Certificate or Articles of Incorporation, as the case may be, bylaws or similar documents of any of the Company’s Subsidiaries, or any agreements as in effect as of the date hereof with respect to matters occurring prior to the Effective Time shall survive the Merger and shall continue in full force and effect. The Parent agrees to cause the Surviving Corporation to comply fully with its obligations hereunder and thereunder.

(c)(i) The Parent or the Surviving Corporation shall maintain the Company’s existing officers’ and directors’ liability insurance (“D&O Insurance”) for a period of not less than six years after the Effective Time; provided, however, that the Parent may substitute therefor policies of substantially equivalent coverage and amounts containing terms no less favorable to such former directors or officers; provided, further, that if the existing D&O Insurance expires or is terminated or cancelled during such period, then the Parent or the Surviving Corporation shall obtain substantially similar D&O Insurance on terms at least as favorable to such former directors or officers.

(ii) Notwithstanding the provisions of Section 7.7(c)(i) above, the Company may at its option, in lieu of complying with the provisions of Section 7.7(c)(i), purchase an extended reporting period endorsement (the “Policy Extension”) under the Company’s existing directors’ and officers’ liability insurance coverage for the Company’s directors and officers which shall provide such directors and officers with coverage for six years following the Effective Time, which policy shall provide coverage amounts, terms, and conditions which are no less favorable to the insured Persons than the directors’ and officers’ liability insurance coverage currently maintained by the Company with respect to acts or omissions occurring prior to or at the Effective Time. The Parent shall take any and all actions necessary or advisable to maintain such Policy Extension, and shall so maintain such Policy Extension, on the terms so purchased and shall not modify or amend the terms thereof in any manner.

(d) In the event the Parent, the Surviving Company, or any of their successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, to the extent necessary, proper provision shall be made so that the successors and assigns of the Parent assume the obligations set forth in this Section 7.7.

(e) The Parent shall unconditionally guarantee the timely payment of all funds owing by, and the timely performance of all other obligations of, the Surviving Corporation under this Section 7.7. From and after the Effective Time, the Parent shall, and shall cause the Surviving Corporation to, pay all expenses, including reasonable attorneys’ fees that may be incurred by the Indemnified Parties in enforcing their indemnity rights and other rights provided in this Section 7.7.

7.8 Third Party Standstill Agreements. During the period from the date of this Agreement through the Effective Time, the Company shall use its commercially reasonable efforts to enforce and shall not terminate, amend, modify or waive (except in accordance with the terms of the applicable agreement) any standstill provision of any confidentiality or standstill agreement between the Company

32

or its Representatives and other parties entered into prior to the date hereof, subject to applicable Law, including without limitation the fiduciary obligations of the board of directors of the Company.

7.9 State Takeover Laws. If any state takeover statute or similar Laws becomes or is deemed to become applicable to the Company or the Merger, then the Company’s board of directors shall, subject to its fiduciary duties as advised of the same by its counsel, take all reasonable action necessary to render such statute inapplicable to the foregoing.

7.10 Stockholder Solicitation and Approvals.

(a) As soon as practicable after the execution of this Agreement, and subject to the terms of this Agreement, including, without limitation, Section 6.2 hereof, the Company shall:

(ii) prepare and file with the SEC a preliminary proxy or information statement relating to the Merger and this Agreement and use its commercially reasonable efforts to obtain and furnish the information required by the rules and regulations of the SEC to be included in the proxy statement and, after consultation with the Purchaser and the Parent, respond promptly to any comments made by the SEC with respect to the preliminary proxy or information statement and cause a definitive proxy or information statement (together with any supplements thereto, the “Proxy Statement”) to be mailed to its stockholders;

(iii) include in the Proxy Statement the recommendation of the Company’s board of directors that stockholders of the Company vote in favor of the approval of the Merger and the adoption of this Agreement; and

(iv) use all commercially reasonable efforts to solicit from holders of Common Stock proxies in favor of the Merger and take all actions reasonably necessary or, in the reasonable opinion of the Purchaser, advisable to secure the approval of stockholders required by the DGCL, the Company’s Certificate of Incorporation, and any other applicable law to effect the Merger.

(b) The Parent agrees promptly to provide the Company with all information regarding the Parent and the Purchaser required to be included in the Proxy Statement, and to otherwise cooperate with the Company in the preparation of the Proxy Statement and other necessary proxy solicitation materials of the Company with respect to the Merger.

7.11 Employee Benefits.

(a) For a period of six months following the Effective Date of this Agreement, the Parent shall provide a notice of termination to any employee of the Company or a Company Subsidiary which notice shall not be less than the greater of (i) that which is required by applicable Law, (ii) two months for U.S. employees who have less than 5 years service, (iii) three months for U.S. employees who have more than 5 but less than 10 years service, and four months for U.S. employees with more than 10 years service.

(b) The Parent agrees to cause the Company or the Surviving Corporation, as the case may be, to honor all contracts and agreements of the Company or any of the Company Subsidiaries, in accordance with their terms, which are applicable with respect to any employee, officer, director or executive or former employee, officer, director, or

33

executive of the Company or of any Company Subsidiary, including without limitation as contemplated by Section 7.11(f) hereof. Notwithstanding the provisions of this Section 7.11 or any other provision of this Agreement, the ability or right of the Company, the Surviving Company or any Company Subsidiary to terminate the employment of any of their respective employees after the Closing Date shall not be limited or restricted in any way (subject to any rights of any such employees pursuant to any contract, agreement, arrangement, policy, plan or commitment). Notwithstanding anything in this Agreement to the contrary, the Parent shall cause the Surviving Corporation to pay all amounts earned by employees of the Company or any Company Subsidiary under any contract, agreement, arrangement, policy, plan or commitment to all employees who are employed by the Company on the Closing Date, and to the extent that such payments are triggered by the Closing and set forth in Section 4.20(b) of the Company Disclosure Schedule, these payments will be made simultaneously with the Closing.

(c) Except as provided in this Section 7.11, nothing in this Agreement shall limit or restrict the rights of the Parent or the Company to modify, amend, terminate or establish employee benefit plans or arrangements, in whole or in part, at any time after the Effective Time.

(d) Promptly following the execution of this Agreement, the Parent and the Company shall cooperate to communicate to employees with respect to the post-Merger employee compensation and benefits. Without the prior approval of the Parent, the Company shall not, during the period prior to the Effective Date, make any written or other communication to its employees relating to post-Merger employee compensation or benefits in a manner designed to increase the compensation and benefits communicated in accordance with the prior sentence.

(e) From and after the Effective Time, the Parent shall, or shall cause the Surviving Corporation and its Subsidiaries to, provide each employee of the Parent or the Surviving Corporation or their respective Subsidiaries who shall have been an employee of the Company or any Company Subsidiary immediately prior to the Effective Time (“Continuing Employees”), for so long as such Continuing Employees remain so employed, health and welfare benefits that are no less favorable, in the aggregate, than those provided to similarly situated employees of the Parent and its Subsidiaries under the Parent Employee Plans (as defined below). Following the Effective Time, the Parent will give each Continuing Employee full credit for prior service with the Company or any Company Subsidiary as if such service was service with the Parent for purposes of (w) eligibility and vesting under any Parent Employee Plans, (x) determination of benefit levels under any Parent Employee Plan or policy relating solely to vacation or severance and (y) determination of “retiree” status under any Parent Employee Plan, in each case for which the Continuing Employee is otherwise eligible and in which the Continuing Employee is offered participation, but except where such credit would result in a duplication of benefits. In addition, the Parent shall waive, or cause to be waived, any limitations on benefits relating to pre-existing conditions to the same extent such limitations are waived under any comparable plan of the Parent and recognize for purposes of annual deductible and out-of-pocket limits under its medical and dental plans, deductible and out-of-pocket expenses paid by Continuing Employees in the calendar year in which the Effective Time occurs. For purposes of this Agreement, the term “Parent Employee Plan” means any “employee pension benefit plan” (as defined in Section 3(2) of ERISA) that is a defined contribution plan, any “employee welfare benefit plan” (as defined in Section 3(1) of ERISA), and any other written plan generally made available to similarly situated employees of Parent in the ordinary course of business by the Parent or any of its Subsidiaries or any entity which is a member of (A) a controlled group of corporations (as defined in Section 414(b) of the Code), (B) a group of trades or businesses under common control (as defined in Section 414(c) of the Code) or (C) an affiliated service group (as defined in Section 414(m) of the Code or the regulations under Section 414(o) of the Code), any of which includes or included the Parent or a Subsidiary of the Parent; provided, however, that for the

34

avoidance of doubt, the term “Parent Employee Plan” shall not include any defined benefit pension plan or any plan providing for post-retirement medical or other welfare benefits.

(f) Simultaneously with the Closing, and subject thereto, the Company (or the Surviving Corporation, as applicable) shall make lump sum cash payments to the employees of the Company identified by the Company in an aggregate amount not to exceed $800,000.

7.12 Stockholder Litigation. The parties will discuss with each other any stockholder litigation relating to the Transactions.

7.13. FIRPTA Certificate. On or prior to the Effective Date, the Company shall deliver to the Parent a properly executed statement certifying that the Company has not been a United States real property holding corporation within the meaning of Section 897(c)(2) of the Code during the applicable period specified in Section 897(c)(1)(A)(ii) of the Code.

(b) by either the Parent or the Company: (i) in the event of an inaccuracy of any representation or warranty of the other party contained in this Agreement which cannot be or has not been cured within thirty (30) days after the giving of written notice of such inaccuracy and which inaccuracy would provide the terminating party with the ability to refuse to consummate the Merger under applicable standard set forth in Section 8.2(a) of this Agreement in the case of the Company and 8.3(a) in the case of the Parent (provided that the terminating party is not then in material breach of any representation or warranty contained in this Agreement under the applicable standard set forth in Section 8.2(a) of this Agreement in the case of the Company and Section 8.3(a) in the case of the Parent, or in material breach of any covenant or other agreement contained in this Agreement), or (ii) in the event of a material breach by the other party of the covenants, agreements, or obligations contained in this Agreement which breach
