     1.6 Company Options.

          (a) At the Effective Time, each then-outstanding Company Option, whether vested or unvested, shall be cancelled as follows: (i) in the case of a Vested Company Option having a per share exercise price less than the Merger Consideration, such Vested Company Option shall be cancelled in exchange for the right to receive from the Surviving Corporation for each share of Company Common Stock subject to such Vested Company Option immediately prior to the Effective Time an amount (subject to any applicable withholding tax) in cash equal to the product of (1) the number of shares of Company Common Stock subject to such Vested Company Option immediately prior to the Effective Time and (2) the amount by which the Merger Consideration exceeds the per share exercise price of such Vested Company Option, or

(ii) in the case of an Unvested Company Option or a Company Option having a per share exercise price equal to or greater than the Merger Consideration, such Company Option shall be cancelled without the payment of cash or issuance of other securities in respect thereof. The cancellation of a Company Option as provided in the immediately preceding sentence shall be deemed a release of any and all rights the holder thereof had or may have had in respect of such Company Option. The aggregate amount paid or payable in respect of the cancellation of the Company Options as set forth in this Section 1.6 is referred to herein as the “Option Consideration.”

          (b) Prior to the Effective Time, the Company shall take such actions as may be necessary to give effect to the transactions contemplated by this Section 1.6, including, but not limited to, satisfaction of the requirements of Rule 16b-3(e) under the Exchange Act.

          (c) The Option Plans shall terminate as of the Effective Time and the provisions in any other plan, program or arrangement providing for the issuance or grant of any other interest in respect of the capital stock of the Company or any Subsidiary thereof shall be canceled as of the Effective Time.

     1.7 Closing of the Company’s Transfer Books. At the Effective Time: (a) all shares of Company Common Stock outstanding immediately prior to the Effective Time shall automatically be canceled and retired and shall cease to exist, and all holders of certificates representing shares of Company Common Stock 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 shares of Company Common Stock outstanding immediately prior to the Effective Time. No further transfer of any such shares of Company Common Stock shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, a valid certificate previously representing any shares of Company Common Stock (other than the Rollover Shares) outstanding immediately prior to the Effective Time (a “Company Stock Certificate”) is presented to the Paying Agent (as defined in Section 1.8(a)) or to the Surviving Corporation or Parent, such Company Stock Certificate shall be canceled and shall be exchanged as provided in Section 1.8.

     1.8 Surrender of Certificates.

          (a) Not less than five (5) business days prior to the Closing Date, Parent shall designate and enter into an agreement with a bank or trust company to serve as Paying Agent in the Merger (the “Paying Agent”). On or before the Effective Time, Parent shall deliver to the Paying Agent, for the benefit of the stockholders of the Company and otherwise for payment in accordance with this Section 1, sufficient cash necessary for the payment of the Merger Consideration as provided in Section 1.5(a)(iii). Funds made available to the Paying Agent shall be invested by the Paying Agent as directed by Parent (it being understood that any and all interest or income earned on funds made available to the Paying Agent pursuant to this Agreement shall be turned over to Parent).

          (b) As promptly as practicable (and no later than five (5) business days) after the Effective Time, Parent shall cause the Paying Agent to mail to each holder of record of a Company Stock Certificate (i) a letter of transmittal in a form reasonably acceptable to the Company which shall specify that delivery shall be effected, and risk of loss and title to the Company Stock Certificates shall pass, only upon actual delivery of the Company Stock Certificates to the Paying Agent and shall be in such form and have such other provisions as Parent shall reasonably specify, and (ii) instructions for use in effecting the surrender of the Company Stock Certificates in exchange for the Merger Consideration, without any interest thereon. Upon surrender of Company Stock Certificates for cancellation to the Paying Agent, together with a duly executed letter of transmittal and such other documents as the Paying Agent shall reasonably require, the holder of such Company Stock Certificates shall be entitled to receive in exchange therefor a check in the amount of the Merger Consideration for each share of Company Common Stock formerly represented thereby to be mailed within ten (10) business days of receipt of such Company Stock Certificate and letter of transmittal, in accordance with Section 1.5(a)(iii), and the Company Stock Certificates so surrendered shall be canceled. At the sole discretion of Parent, Parent may make similar arrangements with the Paying Agent for the payment of the Option Consideration to the holders of the Company Options; provided, however, that the payment of the applicable Option Consideration shall, in all events, be conditioned upon the holder of the applicable Company Option delivering to Parent or the Paying Agent, as applicable, a written termination agreement releasing the Company, Parent and their respective Affiliates from any and all claims the holder thereof may have in respect of such Company Option.

          (c) Promptly following the date that is twelve (12) months after the Effective Time, the Paying Agent shall deliver to Parent all cash and any documents in its possession relating to the transactions described in this Agreement, and the Paying Agent’s duties shall terminate. Thereafter, each holder of a Company Stock Certificate shall thereafter look only to Parent for payment of the Merger Consideration and may surrender such Company Stock Certificate to the Surviving Corporation or Parent and (subject to applicable abandoned property, escheat and similar laws) receive in exchange therefor the Merger Consideration, without any interest thereon. Notwithstanding the foregoing, none of the Paying Agent, Parent, Merger Sub, the Company or the Surviving Corporation shall be liable to a holder of shares of Company Common Stock for any amounts delivered to a public official pursuant to applicable abandoned property, escheat or similar Legal Requirements.

          (d) If any Company Stock Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Company Stock Certificate to be lost, stolen or destroyed, the Paying Agent (or if more than twelve (12) months after the Effective Time, the Surviving Corporation), shall issue in exchange for such lost, stolen or destroyed Company Stock Certificate, the Merger Consideration deliverable in respect thereof determined in accordance with this Section 1. When authorizing such issuance in exchange therefor, the board of directors of the Surviving Corporation may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Company Stock Certificate to deliver to the Paying Agent (or if more than twelve (12) months after the Effective Time, the Surviving Corporation) a bond in such amount as the Surviving Corporation may reasonably request as indemnity against any claim that may be made against

the Surviving Corporation with respect to the Company Stock Certificate alleged to have been lost, stolen or destroyed.

          (e) Except as required by law, no dividends or other distributions with respect to capital stock of the Surviving Corporation with a record date after the Effective Time shall be paid to the holder of any unsurrendered Company Stock Certificate.

          (f) All cash paid in respect of the surrender for exchange of shares of Company Common Stock in accordance with the terms hereof shall be deemed to be in full satisfaction of all rights pertaining to such shares of Company Common Stock. If, after the Effective Time, Company Stock Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Section 1.8.

          (g) The Surviving Corporation (and/or any of its Affiliates) shall be entitled to deduct and withhold from the amounts otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock or any holders of Company Options such amounts as the Surviving Corporation (and/or any of its Affiliates) is required to deduct and withhold with respect to the making of such payment under the Code, or any applicable Legal Requirement, including any provision of state, local or foreign Tax law. To the extent that amounts are so withheld by the Surviving Corporation or its Affiliates, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock, or the holder of Company Options, with respect to which such deduction and withholding was made.

     1.9 Further Action. If, at any time after the Effective Time, any further action is determined by Parent or the Surviving Corporation to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession of and to all rights and property of Merger Sub and the Company, then the officers and directors of the Surviving Corporation and Parent shall be fully authorized (in the name of Merger Sub, in the name of the Company and otherwise) to take such action.

obligation of the Company, enforceable against the Company 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.

     2.24 Inapplicability of Anti-takeover Statutes. The Board of Directors has taken and will take all actions necessary to ensure that the restrictions applicable to business combinations contained in Section 203 of the DGCL are, and will be, inapplicable to the execution, delivery and performance of this Agreement and the Voting Agreements and to the consummation of the Merger and the other Contemplated Transactions.

     2.26 Vote Required. The affirmative vote of the holders of a majority of the shares of Company Common Stock outstanding on the record date for the Company Stockholders’ Meeting and entitled to vote (the “Required Stockholder Vote”) is the only vote of the holders of any class or series of the Company’s capital stock necessary to adopt or approve this Agreement and approve the Merger or the other Contemplated Transactions.

     2.27 Non-Contravention; Consents. Except as set forth in Part 2.27 of the Company Disclosure Schedule, neither (x) the execution, delivery or performance of this Agreement, nor (y) the consummation of the Merger or any of the other Contemplated Transactions, will directly or indirectly (with or without notice or lapse of time):

          (a) contravene, conflict with or result in a violation of (i) any of the provisions of the certificate of incorporation, bylaws or other charter or organizational documents of any of the Acquired Corporations, or (ii) any resolution adopted by the stockholders, the Board of Directors or any committee of the board of directors of any of the Acquired Corporations;

          (b) contravene, conflict with or result in a violation of, or give any Governmental Body or other Person the right to challenge the Merger or any of the other Contemplated Transactions or to exercise any remedy or obtain any relief under, any Legal Requirement or any order, writ, injunction, judgment or decree to which any of the Acquired Corporations, or any of the assets owned or used by any of the Acquired Corporations, is subject;

          (c) contravene, conflict with or result in a violation of any of the terms or requirements of, or give any Governmental Body the right to revoke, withdraw, suspend, cancel, terminate or modify, any Governmental Authorization that is held by any of the Acquired

          (d) contravene, conflict with or result in a violation or breach of, or result in a default under, any provision of any Material Contract, or give any Person the right to: (i) declare a default or exercise any remedy under any Material Contract; (ii) a rebate, chargeback, penalty, or change in the delivery schedule under any Material Contract; (iii) accelerate the maturity or performance of any Material Contract; or (iv) cancel, terminate or modify any term of any Material Contract;

          (e) result in the imposition or creation of any Encumbrance upon or with respect to any asset owned or used by any of the Acquired Corporations (except for minor liens that will not, in any case or in the aggregate, materially detract from the value of the assets subject thereto or materially impair the operations of any of the Acquired Corporations); or

          (f) result in the transfer of any material asset of any of the Acquired Corporations to any Person.

Except as may be required by the Exchange Act, the DGCL, and any foreign antitrust Legal Requirement, none of the Acquired Corporations was, is or will be required to make any filing with or give any notice to, or to obtain any Consent from, any Person in connection with (x) the execution, delivery or performance of this Agreement, or (y) the consummation of the Merger or any of the other Contemplated Transactions.

     2.28 Fairness Opinion. The Special Committee of the Board of Directors has received the written opinion of UBS Securities LLC, financial advisor to the Company (the “Financial Advisor”), dated the date of the Prior Merger Agreement, to the effect that the Merger Consideration (as defined in the Prior Merger Agreement) was fair, from a financial point of view, to the Company Stockholders (other than the Rollover Holders).

     2.29 Financial Advisor. Except for the Financial Advisor, no broker, finder or investment banker is entitled to any brokerage fee, finder’s fee, opinion fee, success fee, transaction fee or other fee or commission in connection with the Merger or any of the other Contemplated Transactions based upon arrangements made by or on behalf of any of the Acquired Corporations. The Company has furnished to Parent accurate and complete copies of all agreements under which any such fees, commissions or other amounts have been paid or may become payable and all indemnification and other agreements related to the engagement of the Financial Advisor. Part 2.29 of the Disclosure schedule contains a good faith estimate of the fees and expenses of any investment banker, broker, advisor or similar party, and any accountant, legal counsel or other Person retained by the Company in connection with this Agreement or the transactions contemplated hereby that are (a) accrued but unpaid through the date of this Agreement; (b) payable conditioned upon the consummation of the Merger and (c) reasonably expected to be incurred from the date of this Agreement through the Effective Time, and such estimates are based upon information provided to the Company by the respective Person.

     2.30 Shanghai Construction Project. Prior to the date hereof, the Company has furnished to Parent a forecast of cash payments to be made by, or on behalf of, the Acquired

Corporations after the date hereof under the Shanghai Construction Contract. Such forecast was prepared in good faith based upon reasonable assumptions and consistent with the terms of the Shanghai Construction Contract. The Company has not made (and will not make) any payments under the Shanghai Construction Contract, other than (a) such payments as are required to be made by the express terms of the Shanghai Construction Contract (as in effect on the date hereof); or (b) payments not in excess of $100,000 in the aggregate.

Except as may be required by any foreign antitrust Legal Requirement, neither Parent nor Merger Sub was, is and will be required to make any filing with or give any notice to, or to obtain any Consent from, any Governmental Body in connection with: (i) the execution, delivery or performance of this Agreement; or (ii) the consummation of the Merger or any of the other Contemplated Transactions.

The Company shall use commercially reasonable efforts to respond as promptly as practicable to any comments of the SEC or its staff concerning the Proxy Statement or the Schedule 13E-3 and shall cause the Proxy Statement to be mailed to its stockholders at the earliest practicable time after the resolution of any such comments. The Company shall notify the Parent promptly upon the receipt of any comments from the SEC or its staff or any other government officials and of any request by the SEC or its staff or any other government officials for amendments or supplements to the Proxy Statement or the Schedule 13E-3 and shall supply the Parent with copies of all correspondence between the Company or any of its representatives, on the one hand, and the SEC, or its staff or any other government officials, on the other hand, with respect to the Proxy Statement or the Schedule 13E-3. Notwithstanding anything to the contrary stated above, prior to filing or mailing the Proxy Statement or the Schedule 13E-3 (including any amendment or supplement to the Proxy Statement or Schedule 13E-3) or responding to any comments of the SEC with respect thereto, (a) the Company shall cooperate and provide the Parent with a reasonable opportunity to review and comment on the Proxy Statement and responses relating thereto and shall consider in good faith and include in such documents and responses comments reasonably proposed by the Parent and (b) the Company and the Parent shall cooperate and provide each other with a reasonable opportunity to review and comment on the Schedule 13E-3 and responses relating thereto and shall consider in good faith comments reasonably proposed by the other party.

     4.5 Company Stockholders’ Meeting.

          (a) The Company shall take all action necessary under all applicable Legal Requirements to call, give notice of and hold a meeting of the holders of Company Common Stock to vote on the adoption and approval of this Agreement (the “Company Stockholders’ Meeting”). The Company Stockholders’ Meeting shall be held (on a date selected by the Company in consultation with Parent) as promptly as reasonably practicable after the date hereof. The Company shall ensure that all proxies solicited in connection with the Company Stockholders’ Meeting are solicited in compliance with all applicable Legal Requirements.

          (b) Subject to Section 4.5(c): (i) the Proxy Statement shall include a statement to the effect that the Board of Directors unanimously (with two abstentions) recommends, based on the recommendation of the Special Committee, that the Company’s stockholders vote to adopt and approve this Agreement at the Company Stockholders’ Meeting (such recommendation of the Board of Directors that the Company’s stockholders vote to adopt and approve this Agreement being referred to as the “Company Board Recommendation”); and (ii) the Company Board Recommendation shall not be withdrawn or modified in a manner adverse to Parent, and no resolution by the Board of Directors of the Company or any committee thereof to withdraw or

modify the Company Board Recommendation in a manner adverse to Parent shall be adopted or proposed; provided, however, that nothing herein shall prevent the Company from postponing or adjourning the Company Stockholders’ Meeting if (1) there are holders of insufficient shares of the Company Common Stock present or represented by a proxy at the Company Stockholders’ Meeting to constitute a quorum at the Company Stockholders’ Meeting, (2) the Company is required to postpone or adjourn the Company Stockholders’ Meeting by applicable Legal Requirement or a request from the SEC or its staff, or (3) the Board of Directors or the Special Committee shall have determined in good faith (after consultation with outside legal counsel) that it is necessary or appropriate to postpone or adjourn the Company Stockholders’ Meeting, including in order to give Company Stockholders sufficient time to evaluate any information or disclosure that the Company has sent to Company Stockholders or otherwise made available to Company Stockholders by issuing a press release, filing materials with the SEC or otherwise (including in connection with any withdrawal or modification of the Company Board Recommendation). The Proxy Statement shall include the opinion of the Financial Advisor referred to in Section 2.29.

          (c) Notwithstanding anything to the contrary contained in Section 4.5(b), at any time prior to the adoption and approval of this Agreement by the Required Stockholder Vote, the Company Board Recommendation may be withdrawn or modified in a manner adverse to Parent if:

               (i) (1) an unsolicited, bona fide written offer to purchase all of the outstanding shares of Company Common Stock is made to the Company and is not withdrawn; (2) such unsolicited, bona fide, written offer was not obtained or made as a direct or indirect result of a breach of this Agreement, the Confidentiality Agreement or any “standstill” or similar agreement under which any Acquired Corporation has any rights or obligations; (3) the Company’s Board of Directors or the Special Committee has determined in good faith (after consulting with its independent financial advisor of nationally recognized reputation) that such offer constitutes a Superior Offer; (4) the Company has provided Parent with notice of such offer and the determination of the Company’s Board of Directors or the Special Committee, and for a period of two business days after the date of such notice, if requested by Parent, the Company shall have engaged in good faith negotiations with Parent to make such adjustments in the terms and conditions of this Agreement in such a manner that obviates the need to withdraw or modify the Company Board Recommendation as a result of such offer; (5) the Company’s Board of Directors or the Special Committee determines in good faith (after consulting with its independent financial advisor of nationally recognized reputation and taking into account any changes to the terms of this Agreement proposed by Parent) that such offer continues to constitute a Superior Offer; (6) the Company’s Board of Directors or the Special Committee determines in good faith, after consulting with its outside legal counsel, that, the withdrawal or modification of the Company Board Recommendation is required in order for the Board of Directors to comply with its fiduciary obligations to the Company Stockholders under applicable Legal Requirements; and (7) the Company Board Recommendation is not withdrawn or modified in a manner adverse to Parent at any time prior to the time at which Parent receives written notice from the Company confirming that the Company’s Board of Directors has determined that such offer is a Superior Offer; or

               (ii) in response to a material development or change in material circumstances occurring or arising after the date hereof, the existence of which was not known by the Board of Directors at or prior to the date hereof (and not relating to any Acquisition Proposal) (such material development or change in circumstances, an “Intervening Event”), if the Board of Directors or the Special Committee determines in good faith, after consultation with its financial advisor and outside legal counsel, that, in light of such Intervening Event, that the withdrawal or modification of the Company Board Recommendation is required in order for the Board of Directors to comply with its fiduciary obligations to the Company Stockholders under applicable Legal Requirements; provided, that, the Company Board of Directors shall not be entitled to exercise its right to withdraw or modify the Company Board Recommendation pursuant to this sentence unless the Company has (1) provided to Parent at least three days’ prior notice (unless the Intervening Event arises fewer than three days prior to the Company Stockholders’ Meeting in which case such notice shall be given as promptly as practicable) advising Parent that the Board of Directors or Special Committee intends to take such action and specifying the reasons therefor in reasonable detail and (2) during such three day period, if requested by Parent, the Company engages in good faith negotiations with Parent to make such adjustments in the terms and conditions of this Agreement in such a manner that obviates the need to withdraw or modify the Company Board Recommendation as a result of the Intervening Event.

          (d) The Company’s obligation to call, give notice of and hold the Company Stockholders’ Meeting in accordance with Section 4.5(a) shall not be limited or otherwise affected by the commencement, disclosure, announcement or submission of any Superior Offer or other Acquisition Proposal, or by any withdrawal or modification of the Company Board Recommendation.

          (e) Nothing in this Agreement shall prohibit or restrict the Company, the Special Committee or the Board of Directors from (i) complying with its disclosure obligations under applicable Legal Requirements with regard to any Acquisition Proposal, including taking and disclosing to its stockholders a position contemplated by Rule 14d-9 or rule 14e-2(a) under the Exchange Act (or any similar communication to stockholders); or (ii) making any “stop-look-and-listen” or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act (and any communication of the type described in this subsection (e) shall not be a “Triggering Event” for purposes of this Agreement).

     Section 5. Certain Covenants of the Parties.

     5.1 Regulatory Approvals. Each party shall use reasonable best efforts to file or otherwise submit, as soon as practicable after the date of this Agreement, all notices, reports and other documents required to be filed by such party with or otherwise submitted by such party to any Governmental Body with respect to the Merger and the other Contemplated Transactions, and to submit promptly any additional information requested by any such Governmental Body. Without limiting the generality of the foregoing, the Company and Parent shall, promptly after the date of this Agreement, prepare and file any notification or other document required to be filed in connection with the Merger under any applicable foreign Legal Requirement relating to antitrust or competition matters. The Company and Parent shall respond as promptly as

practicable to: (i) any inquiries or requests received from the Federal Trade Commission or the Department of Justice for additional information or documentation; and (ii) any inquiries or requests received from any state attorney general, foreign antitrust or competition authority or other Governmental Body in connection with antitrust or competition matters. At the request of Parent, the Company shall agree to divest, sell, dispose of, hold separate or otherwise take or commit to take any other action with respect to any of the businesses, product lines or assets of the Acquired Corporations, provided that any such action is conditioned upon the consummation of the Merger..

     5.2 Employee Benefits.

          (a) All employees of the Acquired Corporations who continue employment with Parent, the Surviving Corporation or any Subsidiary of the Surviving Corporation after the Effective Time (“Continuing Employees”) shall become employees of the Surviving Corporation. Nothing in this Section 5.2(a) or elsewhere in this Agreement shall be construed to create a right in any Company Associate to employment with Parent, the Surviving Corporation or any Subsidiary of the Surviving Corporation, and the employment of each Continuing Employee shall be “at will” employment. Except for Indemnified Persons (as defined in Section 5.3(a)) to the extent of their respective rights pursuant to Section 5.3, no Company Associate or Continuing Employee shall be deemed to be a third party beneficiary of this Agreement.

          (b) If requested by Parent prior to the Closing, the Company shall take (or cause to be taken) all actions necessary or appropriate to terminate, effective no later than the day prior to the date on which the Merger becomes effective, any Company Benefit Plan that contains a cash or deferred arrangement intended to qualify under Section 401(k) of the Code (a “Company 401(k) Plan”). If the Company is required to terminate any Company 401(k) Plan, then the Company shall provide to Parent prior to the Closing Date written evidence of the adoption by the Company’s board of directors of resolutions authorizing the termination of such Company 401(k) Plan (the form and substance of which resolutions shall be subject to the prior review and approval of Parent, which approval shall not be unreasonably withheld). If requested, the Company also shall take such other actions in furtherance of terminating such Company 401(k) Plan as Parent may reasonably request.

     5.3 Indemnification of Officers and Directors.

          (a) All rights to indemnification by any of the Acquired Corporations existing in favor of each individual who is an officer or director of any Acquired Corporation as of the date of this Agreement (each such individual, an “Indemnified Person”) for his acts and omissions as a director or officer of the Company or any Acquired Corporation occurring prior to the Effective Time, as provided in the certificate of incorporation or bylaws (or other similar organizational documents) (as in effect as of the date of this Agreement) and as provided in the Indemnification Contract between the Acquired Corporation and such Indemnified Person (as in effect as of the date of this Agreement) in the form disclosed to Parent prior to the date of this Agreement, shall survive the Merger and shall continue in full force and effect (to the fullest extent such rights to indemnification are available under and are consistent with Delaware law) for a period of six years from the date on which the Merger becomes effective, and Parent shall cause (and enable) the Surviving Corporation to perform its obligations thereunder. In addition,

for a period of six years following the Effective Time, Parent and the Surviving Corporation shall cause the Surviving Corporation and its Subsidiaries to cause the certificate of incorporation (and other organizational documents) of the Surviving Corporation and its Subsidiaries to contain provisions with respect to indemnification, exculpation of liability and advancement of expenses that are at least as favorable as those provisions of the current certificate of incorporation (or other organizational documents) of the Acquired Corporations.

          (b) From the Effective Time until the sixth anniversary of the date on which the Merger becomes effective, the Surviving Corporation shall maintain in effect, for the benefit of the Indemnified Persons with respect to their acts and omissions as directors and officers of the Company occurring prior to the Effective Time, the Existing D&O Policies, to the extent that directors’ and officers’ liability insurance coverage is available on commercially reasonable terms; provided, however, that: (i) the Surviving Corporation may substitute for the Existing D&O Policies a policy or policies of comparable coverage; and (ii) the Surviving Corporation shall not be required to pay annual premiums for the Existing D&O Policies (or for any substitute policies) that exceed, in the aggregate, an amount equal to $300,000 (the “Maximum Premium”). In the event any future annual premiums for the Existing D&O Policies (or any substitute policies) exceed the Maximum Premium in the aggregate, the Surviving Corporation shall be entitled to reduce the amount of coverage of the Existing D&O Policies (or any substitute policies) to the amount of coverage that can be obtained for a premium equal to the Maximum Premium. Prior to the Effective Time, the Company may purchase a six-year “tail” pre-paid policy (the “Tail Policy”) on the Existing D&O Policies which Tail Policy shall be (1) on terms and conditions with respect to coverage and amounts no less favorable, in the aggregate, than the Existing D&O Policies, (2) be for an amount not to exceed the Maximum Premium and (3) name Parent as a successor in interest of such Tail Policy. In the event the Company purchases such Tail Policy prior to the Effective Time, Parent and the Surviving Corporation shall maintain such Tail Policy in full force and effect and continue to honor their obligations thereunder in lieu of all other obligations of Parent and the Surviving Corporation under the first sentence of this Section 5.3(b).

     5.4 Additional Agreements.

          (a) Subject to the terms and conditions set forth in this Agreement (including Section 5.4(b) below), Parent and the Company shall use reasonable efforts to cause to be taken all actions necessary to consummate the Merger and make effective the other Contemplated Transactions. Without limiting the generality of the foregoing, but subject to Section 5.4(b), each party to this Agreement: (i) shall make all filings and other submissions (if any) and give all notices (if any) required to be made and given by such party in connection with the Merger and the other Contemplated Transactions; (ii) shall use reasonable efforts to obtain each Consent (if any) required to be obtained (pursuant to any applicable Legal Requirement or Contract, or otherwise) by such party in connection with the Merger or any of the other Contemplated Transactions; and (iii) shall use reasonable efforts to lift any injunction prohibiting, or any other legal bar to, the Merger or any of the other Contemplated Transactions. The Company shall provide Parent with a copy of each proposed filing with or other submission to any Governmental Body relating to any of the Contemplated Transactions, and shall give Parent a reasonable time prior to making such filing or other submission in which to review and comment

on such proposed filing or other submission. The Company shall promptly deliver to Parent a copy of each such filing or other submission made, each notice given and each Consent obtained by the Company during the Pre-Closing Period.

          (b) Notwithstanding anything to the contrary contained in this Agreement, Parent shall not have any obligation under this Agreement: (i) to dispose of or transfer or cause any of its Subsidiaries to dispose of or transfer any assets, or to commit to cause any of the Acquired Corporations to dispose of or transfer any assets; (ii) to discontinue or cause any of its Subsidiaries to discontinue offering any product or service, or to commit to cause any of the Acquired Corporations to discontinue offering any product or service; (iii) to license or otherwise make available, or cause any of its Subsidiaries to license or otherwise make available to any Person any technology, software or other Intellectual Property or Intellectual Property Right, or to commit to cause any of the Acquired Corporations to license or otherwise make available to any Person any technology, software or other Intellectual Property or Intellectual Property Right; (iv) to hold separate or cause any of its Subsidiaries to hold separate any assets or operations (either before or after the Closing Date), or to commit to cause any of the Acquired Corporations to hold separate any assets or operations; or (v) to make or cause any of its Subsidiaries to make any commitment (to any Governmental Body or otherwise) regarding its future operations or the future operations of any of the Acquired Corporations.

          (c) With respect to the Contract identified on Schedule 5.4, the Company will enter into an amendment thereto, or will otherwise take such actions as are necessary, so that (i) the last payment thereunder in respect of the services performed thereunder shall not be due at any time earlier than February 28, 2011; and (ii) if the Contract is terminated prior to any services being performed, then any amounts paid by the Company in advance under such Contract shall be refunded in full.

     5.5 Disclosure. Parent and the Company will reasonably consult with each other before issuing any press release or otherwise making any public statements about this Agreement or any of the transactions contemplated by this Agreement. Neither Parent nor the Company will issue any such press release or make any such public statement without the prior written consent of the other party, except to the extent that the disclosing party determines in good faith it is required to do so by applicable Legal Requirements or the rules or regulations of the NYSE Amex, in which case that party consult with the other party and will consider the other party’s comments in good faith, and unless the Board of Directors (or Special Committee) believes in good faith that such comments are inappropriate, will implement them, before issuing any such release or making any such public statement.

     5.6 Stockholder Litigation. To the extent permitted by applicable Legal Requirements, in the event that any stockholder litigation relating to the Contemplated Transactions is brought or threatened against the Company or any members of the Company’s Board prior to the Effective Time, the Company shall promptly notify Parent and keep Parent reasonably informed with respect to the status thereof. The Company shall give Parent the opportunity to participate in the defense or settlement of any stockholder litigation against the Company or any members of the Company Board relating to the transaction contemplated by this Agreement, at Parent’s cost. The Company agrees to use commercially reasonable efforts to

enter into such joint defense agreement with Parent, if requested by Parent. The Company shall not agree to any settlement of any stockholder litigation for an amount in excess of $250,000 in the aggregate without Parent’s prior written consent (such consent not to be unreasonably withheld or delayed).

     5.7 Export Control. Prior to the Closing, the Company shall use commercially reasonable efforts to take the actions set forth on Part 5.7 of the Company Disclosure Schedule. With respect to the foregoing, the Company shall (x) promptly notify Parent of any material communication between the Company or its Affiliates and any Governmental Authority; (y) consult with Parent in advance of any substantive meeting or discussion with any Governmental Authority and, to the extent permitted by such Governmental Authority, give Parent or Parent’s Affiliates or Representatives, the opportunity to attend and participate thereat; and (z) subject to applicable Legal Requirements, furnish Parent or Parent’s Representatives with copies of written correspondence and communications between the Company and/or its Affiliates and/or its Representatives on the one hand, and any Governmental Authority or members of their respective staffs on the other hand, including providing Parent or Parent’s Representative with the opportunity to review such material communications in advance of their submission.

This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

     9.2 Waiver.

          (a) No failure on the part of any party to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of any party in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy.

          (b) No party shall be deemed to have waived any claim arising out of this Agreement, or any power, right, privilege or remedy under this Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of such party; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

     9.3 No Survival of Representations and Warranties. None of the representations and warranties contained in this Agreement or in any certificate delivered pursuant to this Agreement shall survive the Merger.

     9.4 Entire Agreement; Counterparts; Exchanges by Facsimile. This Agreement and the other agreements referred to in this Agreement constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among or between any of the parties with respect to the subject matter hereof and thereof; provided, however, that the Confidentiality Agreement shall not be superseded and shall remain in full force and effect in accordance with its terms. This Agreement may be executed in several counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument. The exchange of a fully executed Agreement (in counterparts or otherwise) by facsimile shall be sufficient to bind the parties to the terms and conditions of this Agreement.

     9.5 Applicable Law; Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws. In any action or suit between any of the parties arising out of or relating to this Agreement or any of the transactions contemplated by this Agreement: (a) each of the parties irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the state and federal courts located in the State of Delaware; and (b) each of the parties irrevocably waives the right to trial by jury.

     9.6 Remedies. Except as otherwise provided herein, but subject to Section 9.7, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy.

     9.7 Specific Performance.

          (a) The parties to this Agreement agree that irreparable damage would occur if any provision of this Agreement is not performed in accordance with the terms hereof and that the parties will be entitled to specific performance of the terms hereof in addition to any other remedy at law or equity. Each party to this Agreement, to the extent permitted by Applicable Law, hereby waives any defenses it may have to the remedy of specific performance provided

for herein, waives any requirement for the posting of any bond or other security as a prerequisite for specific performance, and agrees not to raise any objections to the remedy of specific performance in any proceeding brought by any other party to this Agreement. The Company hereby agrees that specific performance shall be its (and any third party beneficiary’s) sole and exclusive remedy with respect to breaches by Parent, Merger Sub or any other Person or otherwise in connection with this Agreement or the Contemplated Transactions, except as provided in Section 9.7(b) below and as expressly provided in the Guarantee (if and to the extent applicable), and subject to Section 9.7(b) below, that none of the Company nor any holder of Company Common Stock may accept any other form of relief that may be available for breach under this Agreement, the Guarantee, any commitment letter (or similar document) or otherwise in connection with this Agreement or the transactions contemplated hereby (including monetary damages).

          (b) Only if a court of competent jurisdiction has declined to specifically enforce the obligations of Parent or Merger Sub to consummate the Merger pursuant to a claim for specific performance brought against Parent or Merger Sub in connection with this Agreement, the Company may enforce any award of damages granted by such court for such alleged breach against Parent, Merger Sub or such other Person and accept damages for such alleged breach only if, within two (2) weeks following such court’s determination, Parent and Merger Sub do not consummate the Merger in accordance with this Agreement. Notwithstanding anything else contained in this Agreement, in no event shall the collective damages payable by Parent, Merger Sub or any of their affiliates, for breaches under this Agreement or the Guarantee exceed the Cap (as defined in the Guarantee) in the aggregate for all such breaches. For the avoidance of doubt, the Company and any third party beneficiary may contemporaneously seek both specific performance and any other form of alternative relief that may be available for breach under this Agreement or otherwise in connection with this Agreement or the Contemplated Transactions (including monetary damages), but no such alternative relief may be accepted unless and until the court has declined to award specific performance. The Company agrees to cause any pending Legal Proceeding seeking any such other relief to be dismissed with prejudice at such time as Parent and Merger Sub consummate the Merger in accordance with this Agreement. The Company, by its acceptance of the benefits of this Agreement and the Guarantee, covenants, agrees and acknowledges that no Person other than the Sponsors shall have any obligation hereunder or thereunder and that no recourse or right of recovery hereunder or thereunder or under any document or instrument delivered in connection herewith or therewith, or for any claim based on, in respect of, or by reason of, such obligations or their creation, against, and no liability shall be attached to, any former, current or future director, officer, agent, Affiliate, employee, general or limited partner, member, manager, stockholder, other equity holder, controlling person or assignee of a Sponsor or any Affiliate thereof or any former, current or future director, officer, agent, Affiliate, employee, general or limited partner, member, manager, stockholder, other equity holder, controlling person or assignee of any of the foregoing (excluding Parent and Merger Sub), through Parent, Merger Sub or otherwise, whether by or through attempted piercing of the corporate veil, by or through a claim by or on behalf of Parent or Merger Sub against any of the foregoing, whether by the enforcement of any assessment or by any legal or equitable proceeding, by virtue of any Legal Requirement, or otherwise.

     9.8 Disclosure Schedules. Each of the Company Disclosure Schedule and the Parent Disclosure Schedule shall be arranged in separate parts corresponding to the numbered and lettered sections contained in Section 2 or Section 3, and the information disclosed in any numbered or lettered part shall be deemed to relate to and to qualify only the particular representation or warranty set forth in the corresponding numbered or lettered section in Section 2 or Section 3, and shall not be deemed to relate to or to qualify any other representation or warranty unless the applicability of the information to any other representation or warranty is readily apparent from the text of such disclosure. For purposes of this Agreement, each statement or other item of information set forth in the Company Disclosure Schedule or in any update to the Company Disclosure Schedule shall be deemed to be a representation and warranty made by the Company in Section 2 and each statement or other item of information set forth in the Parent Disclosure Schedule or in any update to the Parent Disclosure Schedule shall be deemed to be a representation and warranty made by Parent in Section 3.

     9.9 Attorneys’ Fees. In any action at law or suit in equity to enforce this Agreement or the rights of any of the parties under this Agreement, the prevailing party in such action or suit shall be entitled to receive a reasonable sum for its attorneys’ fees and all other reasonable costs and expenses incurred in such action or suit.

     9.10 Assignability; Beneficiaries. This Agreement shall be binding upon, and shall be enforceable by and inure solely to the benefit of, the parties hereto and their respective successors and assigns; provided, however, that neither this Agreement nor any of the Company’s rights or obligations hereunder may be assigned or delegated by the Company without the prior written consent of Parent, and any attempted assignment or delegation of this Agreement or any of such rights or obligations by the Company without Parent’s prior written consent shall be void and of no effect. Nothing in this Agreement, express or implied, is intended to or shall confer upon any Person (other than: (a) the parties hereto; (b) prior to the Effective Time, but subject to Section 9.7(b), for the right of holders of shares of the Company Common Stock (other than the Rollover Holders) to pursue claims for damages and other relief, including equitable relief, for any breach of this Agreement by Parent or Merger Sub; (c) from and after the Effective Time, the former holders of Company Common Stock (other than the Rollover Holders) solely with respect to their right to receive the Merger Consideration in accordance with (and subject to Section 1) and (d) the Indemnified Persons to the extent of their respective rights pursuant to Section 5.3) any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement. Notwithstanding the foregoing, or anything to the contrary contained herein, the rights granted pursuant to clause (b) of this Section 9.10 will only be enforceable on behalf of holders of Company Common Stock by the Company in its sole and absolute discretion, it being understood and agreed that any and all interests in such claims will attach to such shares of the Company Common Stock and subsequently transfer therewith and, consequently, any damages, settlements, or other amounts recovered or received by the Company with respect to such claims (net of expenses incurred by the Company in connection therewith) may, in the Company’s sole and absolute discretion, be (i) distributed, in whole or in part, by the Company to the holders of shares of Company Common Stock of record as of any date determined by the Company or (ii) retained by the Company for the use and benefit of the Company on behalf of its stockholders in any manner the Company deems fit.

Contemplated Transactions (irrespective of the form of the claim or action, whether in contract, tort or otherwise) shall be limited to monetary damages not in excess of such Guarantor’s Pro Rata Portion of the Cap.

          SECTION 2. Nature of Guarantee. During the term hereof, this Guarantee is an unconditional, irrevocable and continuing guarantee of payment and the Obligation to which it applies or may apply under the terms hereof shall be conclusively presumed to have been created in reliance hereon.
