The Estimated Closing Date Balance Sheet shall be substantially in the form of the Company Balance Sheet and shall be prepared in accordance with GAAP and on a basis consistent with and utilizing the same principles, practices and policies as those used in preparing the Company Balance Sheet. The Estimated Closing Date Balance Sheet shall set forth Working Capital as of the Closing Date as derived from the Estimated Closing Date Balance Sheet (the “Estimated Working Capital”).

The Closing Date Balance Sheet shall be substantially in the form of the Company Balance Sheet and shall be prepared in accordance with GAAP and on a basis consistent with and utilizing the same principles, practices and policies as those used in preparing the Company Balance Sheet. The Closing Date Balance Sheet shall set forth Working Capital as of the Closing Date as derived from the Closing Date Balance Sheet (the “Closing Working Capital”). The Stockholder Representative shall be given timely access to all supporting workpapers and any other documentation used in the preparation of the Closing Date Balance Sheet.

(iv) The Stockholder Representative may dispute any amounts reflected on the Closing Date Balance Sheet or the calculation of Closing Working Capital; provided, however, that the Stockholder Representative shall have notified Parent in writing of each disputed item, specifying the amount thereof in dispute and setting forth, in reasonable detail, the basis for such dispute, within twenty (20) days of Parent’s delivery of the Closing Date Balance Sheet pursuant to clause (iii) above.

(v) If the Stockholder Representative shall have delivered a notice of disagreement within the twenty (20) day period referred to in Section 2.6(c)(iv), the Stockholder Representative and Parent shall, during the twenty (20) days following such delivery, use good faith efforts to reach agreement on the disputed items or amounts in order to finally determine the Closing Date Balance Sheet and/or Closing Working Capital. If the Stockholder Representative and Parent are unable to reach agreement concerning the Closing Date Balance Sheet and/or Closing Working Capital during that period, they shall promptly thereafter submit

to Deloitte & Touche LLP (the “Accounting Referee”), and thereafter cause the Accounting Referee to review, the disputed items or amounts for the purpose of final determination of the Closing Date Balance Sheet and/or the calculation of Closing Working Capital. In making such determination and calculations, the Accounting Referee shall consider only those items or amounts in the Closing Date Balance Sheet and/or Parent’s calculation of Closing Working Capital as to which the Stockholder Representative has disagreed in writing. The Accounting Referee shall deliver to the Stockholder Representative and Parent as promptly as practicable (but in no event later than thirty (30) days after submission) a report setting forth the Accounting Referee’s calculation of the disputed amounts. Such report shall be final and binding upon the Stockholder Representative, Parent, the Surviving Corporation, the Stockholders, and all other parties to this Agreement and the resulting Closing Date Balance Sheet and calculation of Closing Working Capital shall be final for all purposes of this Agreement. The Parent and the Stockholders shall each pay their own fees and expenses and one-half of the costs and charges of the Accounting Referee’s review and report. The Stockholders’ share of the costs of the Accounting Referee will be deducted from the Working Capital Escrow.

(vi) The Closing Date Balance Sheet and Closing Working Capital shall be deemed conclusively determined for purposes of this Agreement upon the date (the “Final Determination Date”) that is the earlier of (x) the failure of the Stockholder Representative to notify Parent of a dispute within twenty (20) days of Parent’s delivery of the Closing Date Balance Sheet pursuant to clause (iii) above, (y) the resolution of all disputes pursuant to Section 2.6(c)(v) by agreement of Parent and the Stockholder Representative, and (z) the resolution of all disputes pursuant to Section 2.6(c)(v) by the Accounting Referee.

(vii) In the event that the Closing Working Capital is less than the Estimated Working Capital (such deficiency, the “Working Capital Deficiency”), then Parent shall issue written instructions directing the Escrow Agent to, and the Escrow Agent shall, disburse from the Working Capital Escrow Amount to Parent no later than three (3) Business Days following the Final Determination Date, an amount equal to the Working Capital Deficiency, and the amount of the Working Capital Deficiency shall be deemed a decrease to the Merger Consideration. If the Working Capital Deficiency is greater than the Working Capital Escrow Amount (such shortfall, the “Working Capital Indemnity Amount”), then Parent shall issue written instructions directing the Escrow Agent to, and the Escrow Agent shall, disburse the entire Working Capital Escrow Amount to Parent and disburse the Working Capital Indemnity Amount out of the Indemnity Escrow Amount to Parent in accordance with Section 10.2 of this Agreement and the terms of the Escrow Agreement. If the Working Capital Deficiency is less than the Working Capital Escrow Amount, then Parent shall issue written instructions directing the Escrow Agent to, and the Escrow Agent shall disburse, after making the disbursement specified in the first sentence of this Section 2.6(c)(vii), the balance of the Working Capital Escrow Amount to the Payment Agent for distribution to the Stockholders as Merger Consideration pursuant to this Section 2.6.

(viii) In the event that the Closing Working Capital exceeds the Estimated Working Capital (such excess, the “Working Capital Excess”), then (i) Parent shall pay the Working Capital Excess to the Payment Agent and the amount of the Working Capital Excess shall be deemed an increase to the Merger Consideration and (ii) Parent shall issue

written instructions directing the Escrow Agent to, and the Escrow Agent shall, disburse the remaining Working Capital Escrow Amount to the Payment Agent for distribution to the Stockholders as Merger Consideration pursuant to this Section 2.6. Such amounts shall be paid no later than three (3) Business Days following the Final Determination Date.

(d) Tax Withholding. Parent and the Company shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any Person such amounts as Parent, the Company or the Surviving Corporation determines it is required to deduct and withhold with respect to the making of such payment, or the exercise of Company Options, under the Internal Revenue Code of 1986, as amended (the “Code”), or any other provision of Tax Law. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to such Person in respect of which such deduction and withholding was made.

(e) Escrow. At Closing, Parent, on behalf of the Stockholders, shall deposit with the Escrow Agent a portion of the Merger Consideration equal to the sum of (x) $6,000,000 in cash (the “Indemnity Escrow Amount”) and (y) the Working Capital Escrow Amount. The Stockholders shall be deemed to have deposited with the Escrow Agent (1) the Indemnity Escrow Amount to provide a source of funding to the Indemnified Parties for any Losses for which they are entitled to be indemnified pursuant to Article X and (2) the Working Capital Escrow Amount to provide a source of funding to Parent for any Working Capital Deficiency pursuant to Section 2.6(c)(vii).

(f) Cancellation of Parent-Owned and Company-Owned Stock. Each share of Company Capital Stock owned by Merger Sub, Parent, the Company or any direct or indirect wholly-owned subsidiary of Parent or of the Company immediately prior to the Effective Time shall be canceled and extinguished without any conversion thereof or consideration therefore.

(g) Capital Stock of Merger Sub. Each share of common stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and exchanged for one validly issued, fully paid and non-assessable share of common stock of the Surviving Corporation. Each stock certificate of Merger Sub evidencing ownership of any such shares shall continue to evidence ownership of such shares of common stock of the Surviving Corporation.

(a) Notwithstanding any provision of this Agreement to the contrary, any shares of Company Capital Stock held by a Stockholder who either (i) has demanded and perfected appraisal or dissenters’ rights for such shares in accordance with the DGCL or the CGCL, as applicable, and who, as of the Effective Time, has not effectively withdrawn or lost such appraisal or dissenters’ rights, or (ii) as of the Effective Time, retains the right to demand and perfect dissenters’ rights under the CGCL (collectively, “Dissenting Shares”), shall not be converted into or represent the right to receive the Merger Consideration pursuant to Section 2.6, but the holder thereof shall only be entitled to such rights as are granted by the DGCL or the CGCL, as applicable.

(b) Notwithstanding the provisions of subsection (a), if any Stockholder who holds Dissenting Shares as of the Effective Time shall effectively withdraw or lose (through passage of time, failure to demand or perfect, or otherwise) the right to demand and perfect appraisal or dissenters’ rights under the DGCL and the CGCL, then, as of the later of the Effective Time and the occurrence of such event, such holder’s shares that were Dissenting Shares shall automatically be converted into and represent only the right to receive the Merger Consideration pursuant to and subject to Section 2.6 (including Section 2.6(e)), without interest thereon upon surrender of the certificate representing such shares.

(c) The Company shall give Parent (i) prompt notice of any written demands for appraisal of any shares of Company Capital Stock, demands for purchase by the Company of any shares of Company Capital Stock pursuant to the exercise of dissenters’ rights, withdrawals of such demands, and any other instruments or notices served pursuant to the DGCL or the CGCL, as applicable, on the Company and (ii) the opportunity to participate in all negotiations and proceedings with respect to demands for appraisal under the DGCL or demands for purchase under the CGCL. The Company shall not, except with the prior written consent of Parent, (A) voluntarily make any payment with respect to any demands for appraisal of Company Capital Stock or demands for purchase of Company Capital Stock or (B) offer to settle or settle any such demands. Notwithstanding the foregoing, to the extent that Parent or the Company (y) makes any payment or payments in respect of any Dissenting Shares in excess of the Merger Consideration that otherwise would have been payable in respect of such shares in accordance with this Agreement or (z) incurs any other costs or expenses (including specifically, but without limitation, attorneys’ fees, costs and expenses in connection with any action or proceeding or in connection with any investigation) in respect of any Dissenting Shares (other than payments for such shares) (together “Dissenting Share Payments”), Parent shall be indemnified under the terms of Article X for the amount of such Dissenting Share Payments.

(a) Payment Agent. Prior to the Effective Time, Parent shall designate a United States bank or trust company reasonably acceptable to the Company to act as payment agent (the “Payment Agent”) in the Merger.

(b) Exchange Procedures. Promptly after the Closing, Parent shall cause to be mailed to each holder of record of a certificate or certificates (the “Certificates”) which immediately prior to the Effective Time represented outstanding shares of Company Capital Stock, (A) a letter of transmittal (the “Letter of Transmittal”) which shall specify that delivery of the Certificates shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Payment Agent and shall be in such form and have such other provisions as Parent may specify and (B) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. The Letter of Transmittal shall indicate that applicable withholding Taxes (which have not otherwise been previously withheld and paid to the appropriate Tax authority) with respect to the exercise of Nonstatutory Options will be withheld from the Merger Consideration otherwise payable to each Stockholder who acquired shares of Company Capital Stock pursuant to the exercise of a Nonstatutory Option. Upon delivery of a Letter of Transmittal to the Payment Agent, or to such other agent or agents as may

be appointed by Parent, duly completed and validly executed in accordance with the instructions thereto, together with surrender of a Certificate (or Certificates) for cancellation, the Stockholder shall be entitled to receive in exchange therefore the Merger Consideration to which such Stockholder is entitled pursuant to Section 2.6 (less the amounts to be deposited with the Escrow Agent on such holder’s behalf), and the Certificate(s) so surrendered shall forthwith be canceled. Until so surrendered, each outstanding Certificate that, prior to the Effective Time, represented shares of Company Capital Stock will be deemed from and after the Effective Time, for all corporate purposes, to evidence only the right to receive the Merger Consideration as provided in this Article II.

(i) Within two (2) Business Days after the Effective Time, Parent shall deposit with the Payment Agent the Merger Consideration payable in exchange for outstanding shares of Company Capital Stock; provided, however, that, on behalf of the Stockholders, Parent shall deposit the Indemnity Escrow Amount and the Working Capital Escrow Amount with the Escrow Agent pursuant to Section 2.6(e) and Article X. No interest shall be payable on any cash deliverable upon the exchange of any Company Capital Stock.

(ii) The funds deposited by Parent with the Payment Agent shall be invested by the Payment Agent as directed by Parent or the Surviving Corporation, pending payment thereof by the Payment Agent to the Stockholders. Earnings from such investments shall be the sole and exclusive property of Parent and the Surviving Corporation and no part of such earnings shall accrue to the benefit of any Stockholders.

(d) No Liability. Notwithstanding anything to the contrary in this Section 2.8, none of the Payment Agent, Parent, the Surviving Corporation or any party hereto shall be liable to a holder of shares of Company Capital Stock for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar Law.

2.9 No Further Ownership Rights in Company Capital Stock. The cash amounts paid upon the surrender for exchange of shares of Company Capital Stock in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Company Capital Stock, and there shall be no further registration of transfers on the records of the Surviving Corporation of shares of Company Capital Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article II.

2.10 Lost, Stolen or Destroyed Certificates. In the event any Certificates shall have been lost, stolen or destroyed, the Payment Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, the amount of Merger Consideration in cash as required pursuant to Section 2.6; provided, however, that Parent may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Certificates to deliver a bond in such sum as it may direct

as indemnity against any claim that may be made against Parent, the Surviving Corporation or the Payment Agent with respect to the Certificates alleged to have been lost, stolen or destroyed.

2.11 Taking of Necessary Action; Further Action.

Each such agreement is in full force and effect, and neither the Company nor any of its Subsidiaries is in default thereunder, nor to the knowledge of the Company is any party obligated to the Company or any of its Subsidiaries pursuant to any such agreement in default thereunder.

Each of Parent and Merger Sub has the full corporate power and authority to own its properties and to carry on its business as now being conducted and is duly qualified to do business and is in good standing in each jurisdiction in which the conduct of its business or the ownership, leasing, holding or use of its properties makes such qualification necessary, except such jurisdictions where the failure to be so qualified or licensed or in good standing could not reasonably be expected to have a material adverse effect on the business, assets, liabilities, condition (financial and other) or results of operations of Parent and its subsidiaries on a consolidated basis.

4.2 Authority. Each of Parent and Merger Sub has all requisite corporate power and authority to enter into this Agreement and the Related Agreements to which it is a party and to consummate the transactions contemplated hereby and thereby. The execution and delivery of this Agreement and the Related Agreements to which Parent or Merger Sub is a party and the consummation of the transactions contemplated hereby and thereby have been duly authorized by all necessary corporate action on the part of Parent and Merger Sub. This Agreement has been, and each of the Related Agreements to which Parent or Merger Sub is a party will be at the Closing, duly executed and delivered by Parent and Merger Sub and, assuming the due authorization, execution and delivery by the other parties hereto and thereto (other than Parent and Merger Sub), this Agreement constitutes, and in the case of the Related Agreements they will at Closing constitute, valid and binding obligations of Parent and Merger Sub, enforceable against each of Parent and Merger Sub in accordance with their respective terms, except as such enforceability may be subject to applicable bankruptcy, reorganization, insolvency, moratorium and similar Laws affecting the enforcement of creditors’ rights generally and by general principles of equity. No consent, waiver, approval, order or authorization of, or registration, declaration or filing with, or notice to, any Governmental Entity, including, without limitation, any permits, authorizations or other such actions required by the HSR Act, is required by or with respect to Parent or Merger Sub in connection with the execution and delivery of this Agreement and the Related Agreements by Parent and Merger Sub or the consummation by Parent and Merger Sub of the transactions contemplated hereby or thereby except for (i) the filing of the

Certificate of Merger with the Secretary of State of the State of Delaware and (ii) such consents, approvals, order, authorizations, registrations, declarations, filings and notices as may be required under applicable securities Laws.

4.3 No Conflict. The execution and delivery by Parent and Merger Sub of this Agreement and any Related Agreement to which either is a party do not, and the consummation of the transactions contemplated hereby and thereby will not, result in any violation of or default under (with or without notice or lapse of time, or both), or give rise to a right of termination, cancellation, modification or acceleration of any obligation or loss of any benefit under, (i) any provision of the Certificates of Incorporation or By-laws of Parent or Merger Sub, as in effect on the date hereof, (ii) any contract to which Parent or Merger Sub or any of their respective properties or assets (whether tangible or intangible) is subject, or (iii) any Laws applicable to Parent or Merger Sub or any of their respective properties (whether tangible or intangible) or assets, except, in the case of (ii) or (iii), for such violations or defaults as could not individually or in the aggregate reasonably be expected to have a material adverse effect on the business, assets, liabilities, condition (financial or other) or results of operations of Parent and its subsidiaries on a consolidated basis.

4.4 Litigation. There is no action, suit or proceeding of any nature pending or, to the Parent or Merger Sub’s knowledge, threatened against the Parent or Merger Sub, any of their respective properties or any of their respective officers, directors or Employees, that would have a material adverse effect on the ability of Parent or Merger Sub to perform its obligations pursuant to this Agreement and to consummate the Merger and the transactions contemplated by this Agreement in a timely manner. There is no investigation pending or, to the Parent or Merger Sub’s knowledge, threatened against the Parent or Merger Sub, any of their respective properties or any of their respective officers, directors or employees by or before any Governmental Entity, that would have a material adverse effect on the ability of Parent or Merger Sub to perform its obligations pursuant to this Agreement and to consummate the Merger and the transactions contemplated by this Agreement in a timely manner.

4.5 Brokers’ and Finders’ Fees. Neither Parent nor Merger Sub has incurred, or will incur, directly or indirectly, any brokerage or finders’ fees or agents’ commissions or any similar charges in connection with this Agreement, the Merger or any other transaction contemplated hereby or by the Related Agreements, that would subject the Stockholders to any liability for such fees or commissions or similar charges.

4.6 Financing. Parent and Merger Sub collectively have and will have at the Effective Time sufficient funds to pay the Merger Consideration.

5.1 Stockholder Approval. (a) Immediately upon the execution of this Agreement, the Company shall submit this Agreement and the transactions contemplated hereby to the Stockholders for approval and adoption as provided by the DGCL and CGCL and the Company Certificate of Incorporation and By-laws of the Company. Such submission, and any proxy or consent in connection therewith, shall specify that adoption of this Agreement shall constitute approval by the Stockholders of: (A) the escrow and indemnification obligations of the Stockholders set forth in Section 2.6(e) and Article X hereof and the deposit of the Indemnity Escrow Amount and the Working Capital Escrow Amount with the Escrow Agent, and (B) the appointment of Tim Guleri as Stockholder Representative, with the rights and responsibilities set forth in this Agreement.

(b) Any materials to be submitted to the Stockholders in connection with the solicitation of their approval of the Merger and this Agreement (the “Soliciting Materials”) shall be subject to review and approval by Parent, which approval shall not be unreasonably withheld, and shall include (i) information regarding the Company, the terms of the Merger, this Agreement and the Related Agreements, (ii) the unanimous recommendation of the board of directors of the Company in favor of the Merger, this Agreement, the Escrow Agreement and the other transactions contemplated by this Agreement, and (iii) a statement that the Company’s board of directors has unanimously determined that the terms of the Merger and this Agreement are fair to and in the best interests of the Company and the Stockholders.

(c) Notwithstanding anything to the contrary contained he rein, the Company shall not include in the Soliciting Materials any information with respect to Parent or its Affiliates or the form and content of which shall not have been approved by Parent prior to such inclusion, which approval shall not be unreasonably withheld. The Company shall use its best efforts to obtain, within two (2) Business Days of the date hereof, the consent of its Stockholders sufficient to approve the Merger and this Agreement and to enable the Closing to occur as promptly as practicable following the date hereof.

(d) Notwithstanding the foregoing, the Company shall give the Stockholders sufficient notice such that (i) no Stockholder will be entitled to exercise appraisal rights if such Stockholder has not perfected such appraisal rights prior to Closing, pursuant to Section 262 of the DGCL and (ii) each Stockholder will be entitled to exercise dissenters’ rights under the CGCL. The Company shall consult with Parent as to whether the approval of this Agreement and the Merger and the transactions contemplated hereby by the Stockholders shall be sought by written consent or by means of a Stockholders’ meeting (the “Company Stockholders Meeting”). If approval is sought by means of a Company Stockholders Meeting, then the Company shall consult with Parent regarding the date of the Company Stockholders Meeting and shall not postpone or adjourn (other than for absence of a quorum) the Company Stockholders Meeting without the consent of Parent, which consent shall not be unreasonably withheld.

6.1 Conduct of Business of the Company and Subsidiaries. During the period from the date of this Agreement and continuing until the earlier of the termination of this Agreement and the Effective Time, the Company agrees (except to the extent that Parent shall otherwise consent in writing) to, and to cause each of its Subsidiaries to, carry on its business in the usual and ordinary course in substantially the same manner as heretofore conducted, to pay its debts and Taxes when due, to pay or perform other obligations when due, and, to the extent consistent with such business, to use all reasonable best efforts consistent with past practice and policies to preserve intact its present business organization, keep available the services of its present officers and key employees and preserve their relationships with customers, suppliers, distributors, licensors, licensees, and others having business dealings with it, all with the goal of preserving unimpaired its goodwill and ongoing businesses at the Effective Time. The Company shall promptly notify Parent of any materially negative event involving or adversely affecting the Company, any Subsidiary or their respective businesses. Except as expressly contemplated by this Agreement, the Company shall not, and shall cause each of its Subsidiaries to not, without the prior written consent of Parent:

(a) Reprice any Company Options or Warrants or authorize cash payments in exchange for any outstanding Company Option or Warrant or permit the exercise price of any outstanding Company Option or Warrant to be paid by means other than by cash or check;

(b) Make any payments or enter into any commitment or transaction outside of the ordinary course of business consistent with past practices or in excess of $10,000 in any individual case;

(c) Issue, grant, deliver or sell, or authorize or propose the issuance, grant, delivery or sale of, or purchase or propose the purchase of, any Company Capital Stock or securities convertible into, or subscriptions, rights, warrants or options to acquire, or other agreements or commitments of any character obligating it to issue any such shares or other convertible securities (except for the issuance of Company Common Stock upon exercise of presently outstanding Company Options or Warrants; provided, that (i) the Company timely pays in cash all Taxes required to be withheld and paid in connection with such exercise or conversion, (ii) the amount of such Taxes is contributed to the Company in cash by the Person exercising or converting such Company Option or Warrant, (iii) for purposes of determining the amount of such Taxes, the fair market value of the Company Common Stock received pursuant to such exercise or conversion is equal to the maximum aggregate consideration payable with respect to such Company Common Stock pursuant to this Agreement, including for this purpose any consideration to be deposited with the Escrow Agent as part of the Indemnity Escrow Amount or Working Capital Escrow Amount, and (iv) the Company promptly notifies Parent of such exercise or conversion);

(d) Acquire or agree to acquire by merging or consolidating with, or by purchasing any assets or equity securities of, or by any other manner, any business or any Person

or division thereof, or otherwise acquire or agree to acquire outside of the ordinary course of business any assets in any amount, or in the ordinary course of business in an amount in excess of $10,000 in the case of a single transaction or in excess of $20,000 in the aggregate;

(e) Hire any Employees, or encourage any Employees to resign from the Company, or promote any Employees or change the employment status or titles of any of the Employees, except for the hiring of Employees at non-executive levels in the ordinary course of business at compensation rates comparable to other Employees at similar levels;

(f) Engage in any action with the intent to directly or indirectly adversely impact any of the transactions contemplated by this Agreement;

(g) Take any action that would have been a breach of any of the provisions of Section 3.9 had such action occurred after the Balance Sheet Date and prior to the date of this Agreement (without regard for disclosures in the Company Schedules); or

(h) Take, or agree in writing or otherwise to take, any of the actions described in Sections 6.1(a) through (g) above, or any other action that would prevent the Company from performing or cause the Company not to perform its covenants hereunder.

7.1 Access to Information. The Company shall afford Parent and its accountants, legal counsel, and other representatives complete and timely access during normal business hours during the period prior to the Effective Time to (a) all of the properties, books, contracts, commitments and records of the Company and its Subsidiaries and (b) all other information concerning the business, properties, products, services and personnel of the Company and its Subsidiaries as Parent may reasonably request. To the extent available, the Company agrees to provide Parent and its accountants, legal counsel, and other representatives copies of internal financial statements promptly upon request. No information or knowledge obtained in any investigation pursuant to this Section 7.1 or otherwise shall affect or be deemed to modify any representation or warranty contained herein or the conditions to the obligations of the parties to consummate the Merger.

7.2 Confidentiality. The parties acknowledge that the Company and Parent have previously executed a Mutual Nondisclosure Agreement, dated as of September 17, 2004 (the “Nondisclosure Agreement”), which Nondisclosure Agreement will continue in full force and effect in accordance with its terms.

7.3 Public Disclosure. Unless otherwise required by Law (including without limitation applicable securities Laws) or, as to Parent, by regulatory authority, prior to the Effective Time no disclosure (whether or not in response to an inquiry) of the subject matter of this Agreement shall be made by any party hereto (other than disclosures to Stockholders pursuant to Section 5.1 and other than a press release, Form 8-K and a stockholder conference

call by Parent in connection with the execution of this Agreement) unless approved by Parent and the Company prior to release, provided, however, that such approval shall not be unreasonably withheld. Notwithstanding the immediately preceding sentence, in the event that either party is required by Law or Governmental Entity to make any such disclosure, such party shall notify the other party prior to making such disclosure and shall use its reasonable best efforts to give the other party an opportunity to comment on such disclosure.

7.4 Consents. The Company shall promptly apply for or otherwise seek and use its reasonable best efforts to obtain all consents and approvals required to be obtained by it for the consummation of the Merger, including all consents, waivers, or approvals under any of the Contracts in order to preserve the benefits thereunder for the Surviving Corporation and otherwise in connection with the Merger.

7.5 Conditions to the Merger; Further Assurances. Each of the parties to this Agreement shall use its reasonable best efforts to effectuate the transactions contemplated hereby and to fulfill and cause to be fulfilled the conditions to closing under this Agreement. Each of the parties to this Agreement shall use its reasonable best efforts to comply promptly with all legal requirements which may be imposed on such party with respect to the Merger and will promptly cooperate with and furnish information to any other party hereto in connection with any such requirements imposed upon such other party in connection with the Merger. Each party will use its reasonable best efforts to obtain and make (and will cooperate with the other parties in obtaining or making) any consent, authorization, order or approval of, or any registration, declaration, or filing with, or an exemption by, any Governmental Entity, or other third party, required to be obtained or made by such party or its Subsidiaries in connection with the Merger or the taking of any action contemplated thereby or by this Agreement; provided, however, Parent shall not be required to agree to any divestiture by Parent or the Company or any of Parent’s Affiliates of any shares of capital stock or of any business, assets or property of Parent or its Affiliates or of the Company or its affiliates, or the imposition of any material limitation on the ability of any of them to conduct their businesses or to own or exercise control of such assets, property and stock. Each party hereto, at the request of another party hereto, shall execute and deliver such other instruments and do and perform such other acts and things as may be reasonably necessary or desirable for effecting completely the consummation of the Merger and the other transactions contemplated by this Agreement and the Related Agreements.

7.6 Notification of Certain Matters. The Company shall give prompt written notice to Parent, and Parent shall give prompt written notice to the Company, of (i) the occurrence or non-occurrence of any event which is likely to cause any representation or warranty of the Company, on the one hand, or Parent or Merger Sub, on the other hand, contained in this Agreement to be untrue or inaccurate in any material respect at or prior to the Effective Time and (ii) any failure of the Company or Parent, as applicable, to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it hereunder; provided, however, that the delivery of any notice pursuant to this Section 7.6 shall not limit or otherwise affect any remedies available to the party receiving such notice.

(a) Subject to the other provisions of this paragraph, Parent agrees that all full-time Employees of the Company who continue employment with the Surviving Corporation after the Effective Time (the “Continuing Employees”) shall have the opportunity to participate, or to continue to participate, in employee benefit plans and arrangements of the Surviving Corporation or, at Parent’s election, of the Parent, that provide the following benefits: 401(k), health, dental, life insurance, long-term disability, as well as any other employee benefits and arrangements available generally to the full-time employees of Parent on the same terms and conditions as are available to such Parent employees (the “Plans”). Participation of the Continuing Employees in such Plans shall be in accordance with the terms and conditions of the Plans; provided, however, that nothing in this Section 7.8 or elsewhere in this Agreement shall limit the right of Parent or the Surviving Corporation to amend or terminate any such Plan at any time. Nothing in this Section 7.8 or elsewhere in this Agreement shall be construed to create a right in any Employee to employment with Parent, the Surviving Corporation or any other Subsidiary of Parent, and the employment of each Continuing Employee shall be “at will” employment, if permitted under applicable Law.

(b) The Company agrees that the Board of Directors of the Company, prior to the Effective Time, will vote to terminate prior to the Effective Time the Company’s 401(k) plan, and any other pension plan that it sponsors or maintains for the benefit of any of the Employees, and will authorize the appropriate officers of the Company to use their best efforts to take all other necessary actions to complete the termination of said plans, including, but not limited to, the distribution of assets as soon as practicable thereafter.

7.9 Company Options. Effective as of the Effective Time, Parent shall assume the Company Option Plans and the option agreements representing the Company Options (the “Option Agreements”) with respect to the Unvested Options; provided, however, that (i) each Unvested Option so assumed shall thereafter be exercisable for such number of shares of Parent Common Stock as equals the number of unvested shares of Company Common Stock subject to such Unvested Option multiplied by the Option Exchange Ratio, (ii) the exercise price per share of each such assumed Unvested Option shall be equal to the exercise price per share set forth in the Option Agreement for such Unvested Option divided by the Option Exchange Ratio, and (iii) the vesting schedule for such assumed Unvested Option shall remain unchanged and as set forth in the Option Agreement for such assumed Unvested Option without any acceleration whatsoever. The Company and the Administrator of the Company Option Plans (the “Administrator”) shall take all actions necessary or required under the Company Option Plans and the Option Agreements to cause (i) the Company Option Plans and all Unvested Options to be assumed on the terms and conditions set forth in the preceding sentence such that the vesting of no Company Options is accelerated, (ii) all Vested Options, to the extent not previously exercised, to be terminated effective as of immediately prior to the Effective Time, and (iii) the Company Option Plans to be amended such that, after the Effective Time, (x) no further option grants may be made under the Company Option Plans, (y) outstanding Options cannot be repriced and (z) the exercise price for outstanding Options may be paid only in cash or by check.

7.10 Company Warrants. The Company shall take all action necessary or required under the Warrants to cause such Warrants to be exercised, and if not exercised terminated, effective as of immediately prior to the Effective Time.

7.11 Termination of Company Investor Rights. The Company shall take such steps as may be necessary to terminate, as of the Closing, all Company investor rights granted by the Company to the Stockholders and in effect prior to the Closing, including, without limitation, rights of co-sale, voting, registration, first refusal, board observation or information or operational covenants.

7.12 No Solicitation. (a) Until the earlier of the Effective Time and the date of termination of this Agreement pursuant to Section 11.1 hereof, the Company shall not (nor shall the Company permit any of its Subsidiaries or any of their respective officers, directors, employees, stockholders, advisors, agents, representatives or Affiliates to), directly or indirectly, take any of the following actions with any Person other than Parent and its designees: (a) solicit, encourage, seek, entertain, support, assist, initiate or participate in any inquiry, negotiations or discussions, or enter into any agreement, with respect to any offer or proposal to acquire all or any material part of the business, assets or technologies of the Company or its Subsidiaries, or any amount of the Company Capital Stock or capital stock of any Subsidiary (whether or not outstanding), whether by merger, purchase of assets, purchase of securities, tender offer, license or otherwise, or effect any such transaction (a “Proposal”), (b) disclose any information to any Person concerning the business, technologies or properties of the Company or its Subsidiaries, or afford to any Person access to their respective properties, technologies, books or records, not customarily afforded such access, (c) assist or cooperate with any Person to make any Proposal, or (d) enter into any agreement with any Person with respect to a Proposal. The Company shall immediately cease and cause to be terminated any such negotiations, discussions or agreements (other than with Parent) that are the subject matter of clause (a), (b), (c) or (d) above.

(b) Notwithstanding the foregoing, the Board of Directors of the Company, directly or indirectly through advisors, agents or other intermediaries, at any time prior to the time the Merger has been approved by the Stockholders, may, in response to a bona fide written Proposal from a third party that was not solicited by the Company, any of its Subsidiaries or Affiliates or any of their respective officers, directors, employees, stockholders, agents, advisors, representatives or Affiliates and that involves the acquisition by the third party of at least a majority of the outstanding shares of Company Capital Stock (an “Acquisition Proposal”), provide information concerning the Company to, and engage in negotiations and discussions with, the third party proposing or offering the Acquisition Proposal if the Company receives from the third party so requesting such information an executed confidentiality agreement (a copy of which shall be provided to Parent for informational purposes) the terms of which are (without regard to the terms of the Acquisition Proposal) (x) no less favorable to the Company and (y) no less restrictive on the third party requesting such information than those contained in the Nondisclosure Agreement. In the event that (w) the Acquisition Proposal does not contain a financing contingency, (x) the Board of Directors of the Company determines in good faith (after consultation with its financial advisor and outside legal counsel) that the Acquisition Proposal, if accepted, is reasonably likely to be consummated, (y) the Board of Directors of the Company determines in good faith (after consultation with its outside legal counsel and its financial

advisor) that the Acquisition Proposal would, taking into account all relevant material terms of such Acquisition Proposal and this Agreement, if consummated, result in a transaction that (1) involves the acquisition by the third party of all or substantially all of the outstanding shares of Company Capital Stock, (2) is superior, from a financial point of view, to the Stockholders than the Merger and (3) is more favorable generally to the Stockholders than the Merger (any Acquisition Proposal as to which such determinations have been made being referred to in this Agreement as a “Superior Proposal”) and (z) the Board of Directors determines in good faith (after consultation with its outside legal counsel) that the failure to take such action would result in a breach of its fiduciary duties under applicable Law, then the Company shall be entitled to terminate this Agreement pursuant to and subject to the conditions of Section 11.1(g) hereof.

(c) Nothing in this Section 7.12 shall permit the Company to enter into any agreement, orally or in writing, with respect to a Proposal during the term of this Agreement (other than a confidentiality agreement as described above). After the date hereof and before the Effective Time, neither the Company’s Board of Directors nor any committee thereof shall (i) withdraw or modify, or propose publicly to withdraw or modify, in a manner adverse to Parent, its recommendation to the Stockholders that they approve this Agreement and the Merger or (ii) approve or recommend, or propose publicly to approve or recommend, any Proposal. Notwithstanding the foregoing, at any time after the date hereof and prior to the time this Agreement and the Merger has been approved by the Stockholders, the Company’s Board of Directors, as a result of a Superior Proposal, may withdraw or modify in a manner adverse to Parent its recommendation to the Stockholders that they approve this Agreement and the Merger if and only to the extent that the Company’s Board of Directors determines in good faith (after consultation with its outside legal counsel and its financial advisor) that the failure to take such action would result in a breach of its fiduciary duties under applicable Law. The Company shall advise Parent in writing of any Proposal (including the terms thereof and the identity of the Person making the Proposal) and inquiries with respect to any Proposal within 24 hours of the receipt of such Proposal or inquiry and shall keep Parent informed on a current basis of the status of any discussions regarding a Proposal.

(d) The parties hereto agree that irreparable damage would occur in the event that the provisions of this Section 7.12 were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed by the parties hereto that Parent shall be entitled to an immediate injunction or injunctions, without the necessity of proving the inadequacy of money damages as a remedy and without the necessity of posting any bond or other security, to prevent breaches of the provisions of this Section 7.12 and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which Parent may be entitled at law or in equity. Without limiting the foregoing, it is understood that any violation of the restrictions set forth above by any officer, director, employee, stockholder, agent, advisor, representative, Subsidiary or Affiliate of the Company shall be deemed to be a breach of this Agreement by the Company.

7.13 Resignation of Officers and Directors. The Company shall obtain the resignations of the officers and directors of the Company and its Subsidiaries, effective as of the Effective Time.

(a) For a period of six (6) years after the Effective Time, Parent agrees that it will indemnify, defend and hold harmless each director and officer of the Company (when acting in such capacity) determined as of immediately prior to the Effective Time (the “Company Indemnified Parties”), to the fullest extent that the Company would have been required or permitted under the Company Certificate of Incorporation and By-laws in effect on the date hereof (the “Company Indemnification Obligations”), against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages or liabilities (collectively, “Costs”) incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of matters existing or occurring at or prior to the Effective Time which are asserted after the Effective Time. In connection therewith, Parent shall also advance expenses to the Company Indemnified Parties as incurred to the fullest extent permitted under the Company Indemnification Obligations; provided, however, that the Person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Person is not entitled to indemnification. However, the foregoing provisions of this Section 7.14 shall not apply to: (i) any claim for indemnification made pursuant to Article X hereof, (ii) any matter that, were it asserted by a third party against Parent or the Surviving Corporation, would be an indemnifiable claim pursuant to Article X hereof, or (iii) any claim or matter that relates to a willful or intentional breach of a representation, warranty or covenant made by the Company in connection with this Agreement or the transactions contemplated hereby or made by a Stockholder in connection with its Voting Agreement.

(b) Any Company Indemnified Party wishing to claim indemnification under paragraph (a) of this Section 7.14 upon learning of any such claim, action, suit, proceeding or investigation, shall promptly notify Parent thereof. In the event of any such claim, action, suit, proceeding or investigation, (i) Parent or the Surviving Corporation shall have the right to assume the defense thereof and, provided that Parent or Surviving Corporation does promptly assume and defend such claim, Parent shall not be liable to such Company Indemnified Parties for any legal expenses of other counsel or any other expenses subsequently incurred by such Company Indemnified Parties in connection with the defense thereof, (ii) the Company Indemnified Parties will cooperate in the defense of any such matter and (iii) Parent shall not be liable for any settlement effected without its prior written consent; and provided, further, that Parent shall not have any obligation hereunder to any Company Indemnified Party if and when a court of competent jurisdiction shall ultimately determine, and such determination shall have become final, that the indemnification of such Company Indemnified Party in the manner contemplated hereby is prohibited by applicable Law; and provided further, that any Company Indemnified Party shall have the right to employ separate counsel in any such action and to participate in the defense thereof in the event the representation of such Company Indemnified Party by counsel retained by or on behalf of the Parent or the Surviving Corporation would be inappropriate due to conflicts of interest, as established by the reasonable advice of Parent’s counsel, between any such Company Indemnified Party and any other party represented by such counsel in such proceeding or actions, in which case such Company Indemnified Party and Parent each shall pay, as incurred, one-half the fees and expenses of such separate counsel.

(c) Parent will not, nor will Parent permit the Surviving Corporation to, merge or consolidate with any other Person or sell all or substantially all of the Parent’s or the Surviving Corporation’s assets unless Parent or the Surviving Corporation will ensure that the surviving or resulting entity assumes the obligations imposed by this Section 7.14.

(d) The provisions of this Section 7.14 are intended to be for the benefit of, and shall be enforceable by, each of the Company Indemnified Parties and their heirs and estates.

8.1 Tax Representations. Subject to such exceptions as are disclosed in the Company Schedules, the Company hereby represents and warrants to each of Parent and Merger Sub, as of the date hereof and as of the Closing, as follows:

(a) The Company and each Subsidiary have timely filed all material Tax Returns required to be filed (determined without regard to extensions). The Company and each Subsidiary have paid all Taxes owed (whether or not shown, or required to be shown, on Tax Returns). The Company and each of its Subsidiaries have withheld and paid all Taxes required to have been withheld and paid. All Tax Returns filed by the Company and the Subsidiaries were complete and correct in all material respects, and such Tax Returns correctly reflected the facts regarding the income, business, assets, operations, activities, status and other matters of the Company and the Subsidiaries and any other information required to be shown thereon. Neither the Company nor any Subsidiary has participated, within the meaning of Treasury Regulation Section 1.6011-4(c), in (i) any “reportable transaction” within the meaning of Section 6011 of the Code and the Treasury Regulations thereunder, (ii) any “confidential corporate tax shelter” within the meaning of Section 6111 of the Code and the Treasury Regulations thereunder, or (iii) any “potentially abusive tax shelter” within the meaning of Section 6112 of the Code and the Treasury Regulations thereunder. The Company and each Subsidiary have disclosed on their Tax Returns all positions taken therein that could give rise to a substantial understatement of Tax within the meaning of Section 6662 of the Code (or any similar provision of state, local or foreign Tax law). There are no Liens for Taxes upon any of the Company’s or any Subsidiary’s assets, other than Liens for Taxes not yet due and payable, and there is no reasonable basis for the imposition of such Liens.

(b) None of the Tax Returns filed by the Company or any Subsidiary or Taxes payable by the Company or any Subsidiary have been the subject of an audit, action, suit, proceeding, claim, examination, deficiency or assessment by any Governmental Entity, and no such audit, action, suit, proceeding, claim, examination, deficiency or assessment is currently pending or, to the Company’s knowledge, is contemplated.

(c) Neither the Company nor any Subsidiary is currently the beneficiary of any extension of time within which to file any Tax Return, and neither the Company nor any Subsidiary has waived any statute of limitation with respect to any Tax or agreed to any

extension of time with respect to a Tax assessment or deficiency. All material elections with respect to Taxes affecting the Company or any Subsidiary, as of the date hereof, are set forth in the Company Financial Statements, the Company Tax Returns or in Schedule 8.1.

(d) Neither the Company nor any Subsidiary is a party to any agreement, contract, arrangement or plan (including without limitation the Company Options and Company Restricted Stock) that has resulted or would result, separately or in the aggregate, in the payment of (i) any “excess parachute payments” within the meaning of Section 280G of the Code (without regard to the exceptions set forth in Sections 280G(b)(4) and 280G(b)(5) of the Code) or (ii) any amount for which a deduction would be disallowed or deferred under Section 162 or Section 404 of the Code. None of the shares of outstanding capital stock of the Company or any Subsidiary is subject to a “substantial risk of forfeiture” within the meaning of Section 83 of the Code. No portion of the Merger Consideration is subject to the Tax withholding provisions of Section 3406 of the Code, or of Subchapter A of Chapter 3 of the Code or of any other provision of law.

(e) Neither the Company nor any Subsidiary is a party to or member of any joint venture, partnership, limited liability company or other arrangement or contract which could be treated as a partnership for federal income tax purposes. Neither the Company nor any Subsidiary has ever filed a consent pursuant to former Section 341(f) of the Code, relating to collapsible corporations, and former Section 341(f)(2) does not apply to any of the Company’s or any Subsidiary’s assets. Neither the Company nor any Subsidiary is, or has been, a U.S. real property holding company (as defined in Section 897(c)(2) of the Code) during the applicable period specified in Section 897(c)(1)(A)(ii) of the Code. Neither the Company nor any Subsidiary owns an interest in real property in any jurisdiction in which a Tax is imposed, or the value of the interest reassessed, on the transfer of an interest in real property and which treats the transfer of an interest in an entity that owns an interest in real property as a transfer of the interest in real property. Neither the Company nor any Subsidiary has ever been either a “controlled corporation” or a “distributing corporation” (within the meaning of Section 355(a)(1)(A) of the Code) with respect to a transaction that was described in, or intended to qualify as a tax-free transaction pursuant to Section 355 of the Code. Neither the Company nor any Subsidiary has made or agreed to make any adjustment under Section 481(a) of the Code (or any corresponding provision of state, local or foreign Tax law) by reason of a change in accounting method or otherwise, and will not be required to make such an adjustment as a result of the transactions contemplated by this Agreement. Neither the Company nor any Subsidiary has participated in an international boycott as defined in Section 999 of the Code. Neither the Company nor any Subsidiary has ever (i) made an election under Section 1362 of the Code to be treated as an S corporation for federal income tax purposes or (ii) made a similar election under any comparable provision of any state, local or foreign Tax law.

(g) The unpaid Taxes of the Company and its Subsidiaries did not, as of the Balance Sheet Date, exceed the reserve for actual Taxes (as opposed to any reserve for deferred Taxes established to reflect timing differences between book and Tax income) as shown on the Company Balance Sheet, and will not exceed such reserve as adjusted for the passage of time through the Closing Date in accordance with the reasonable past custom and practice of the Company and its Subsidiaries in filing Tax Returns. Neither the Company nor any Subsidiary will incur any liability for Taxes from the Balance Sheet Date through the Closing Date other than in the ordinary course of business.

As an integral term of the Merger, each Stockholder, jointly and severally, shall indemnify, defend and hold harmless Parent, Merger Sub, the Surviving Corporation and each of their officers, directors, employees, members, agents and Affiliates (the “Indemnified Parties”) against any and all claims, losses, liabilities, damages, deficiencies, interest and penalties, costs and expenses, including reasonable attorneys’ fees and expenses, and expenses of investigation and defense (hereinafter individually a “Loss” and collectively “Losses”; provided, however, that “Losses” shall not include any amounts actually received by the Company in respect of insurance) incurred or suffered by any such Indemnified Parties directly or indirectly as a result of, with respect to or in connection with (i) the failure of any representation or warranty of the Company set forth herein or in any certificate, document or other instrument delivered pursuant to or in connection with this Agreement to be true and correct in all respects as of the date of this Agreement and as of the Closing Date, (ii) any failure by the Company to fully perform, fulfill or comply with any covenant set forth herein or in any certificate, document or other instrument delivered pursuant to or in connection with this Agreement, (iii) any Dissenting Share Payments, (iv) any Acquisition Expenses Deficiency, (v) the Working Capital Indemnity Amount, and (vi) any Stockholder claims relating to or arising out of the Merger, this Agreement or the transactions contemplated hereby, except for claims arising out of or related to disputing a claim to indemnification made by an Indemnified Party hereunder. The Indemnity Escrow Amount shall be available to reimburse the Indemnified Parties for any Losses for which they are entitled to be indemnified pursuant to this Section 10.2. The waiver by Parent and Merger Sub of any of the conditions set forth in Article IX shall not effect the provisions of this Article X.

10.3 Limitations. Except with respect to Losses incurred or suffered by any Indemnified Party directly or indirectly as a result of, with respect to or in connection with any breach or inaccuracy of any of the Fundamental Representations, the sole and exclusive remedy of the Indemnified Parties for money damages with respect to indemnification pursuant to Section 10.2(i) shall be to make claims against the Indemnity Escrow Amount in accordance with the Escrow Agreement. No claims shall be made by any Indemnified Party against the Indemnity Escrow Amount pursuant to Section 10.2(i) hereof, other than any claims arising from any breach or inaccuracy of any of the Fundamental Representations, unless and until the aggregate amount of Losses for which the Indemnified Parties are entitled to be indemnified pursuant to Section 10.2(i) exceed $200,000 and then only to the extent of such excess. The indemnification obligation of each Stockholder for money damages pursuant to Section 10.2(i) with respect to or in connection with any breach or inaccuracy of any of the Fundamental Representations shall be limited to the aggregate gross amount of Merger Consideration such Stockholder has received pursuant to this Agreement and the Merger. Parent, Merger Sub, and the Indemnified Parties agree that the sole and exclusive remedy for money damages for any matters relating to this Agreement, the Escrow Agreement and any certificate or instrument

delivered pursuant hereto shall be the rights to indemnification set forth in this Article X. Notwithstanding anything in this Article X to the contrary, nothing in this Agreement shall limit (i) any right or remedy for fraud, intentional misrepresentation or willful breach or misconduct or (ii) any equitable remedy, including a preliminary or permanent injunction or specific performance.

(a) Promptly after the discovery of any Loss or Losses by any Indemnified Party which might give rise to indemnification hereunder, the Indemnified Party shall deliver to the Stockholder Representative a certificate (the “Claim Certificate”), which Claim Certificate shall:

(i) state that the Indemnified Party has paid or properly accrued Losses, or anticipates that it will incur liability for Losses, for which such Indemnified Party is entitled to indemnification pursuant to this Agreement; and

(ii) specify in reasonable detail, to the extent available, each individual item of Loss included in the amount so stated, the date such item was paid or properly accrued, the basis for any anticipated liability and the nature of the misrepresentation, default, breach of warranty or breach of covenant or claim to which each such item is related and the computation of the amount to which such Indemnified Party claims to be entitled hereunder.

(b) In case the Stockholder Representative shall object to the indemnification of an Indemnified Party in respect of any claim or claims specified in any Claim Certificate, the Stockholder Representative shall, within thirty (30) days after receipt by the Stockholder Representative of such Claim Certificate, deliver to the Indemnified Party a written notice to such effect and the Stockholder Representative and the Indemnified Party shall, within the thirty-day period beginning on the date of receipt by the Indemnified Party of such written objection, attempt in good faith to agree upon the rights of the respective parties with respect to each of such claims to which the Stockholder Representative shall have so objected. If the Indemnified Party and the Stockholder Representative shall succeed in reaching agreement with respect to any of such claims, the Indemnified Party and the Stockholder Representative shall promptly prepare and sign a memorandum setting forth such agreement. Should the Indemnified Party and the Stockholder Representative be unable to agree as to any particular item or items or amount or amounts, then the Indemnified Party shall be entitled to pursue its available remedies for resolving its claim for indemnification.

(c) Promptly after the assertion by any third party of any claim against any Indemnified Party (a “Third Party Claim”) that, in the judgment of such Indemnified Party, may result in the incurrence by such Indemnified Party of Losses for which such Indemnified Party would be entitled to indemnification pursuant to this Agreement, such Indemnified Party shall deliver to the Stockholder Representative a written notice describing in reasonable detail such Third Party Claim; provided, however, that no delay on the part of the Indemnified Party in notifying the Stockholder Representative shall relieve the Stockholders of any liability or obligations hereunder, except to the extent that the Stockholders have been materially prejudiced

thereby, and then only to such extent. The Indemnified Party shall have the right in its sole discretion to conduct the defense of any such Third Party Claim; provided, however, that the Stockholders shall not be liable to indemnify any Indemnified Party for any settlement of any such Third Party Claim effected without the prior written consent of the Stockholder Representative, which consent shall not be unreasonably withheld. If any such action or claim is settled with the prior written consent of the Stockholder Representative, or if there be a final judgment for the plaintiff in any such action, the Indemnified Party shall be entitled to indemnification for the amount of any Loss relating thereto.

(d) Claims for Losses specified in any Claim Certificate to which the Stockholder Representative did not object in writing within thirty (30) days of receipt of such Claim Certificate, claims for Losses covered by a memorandum of agreement of the nature described in Section 10.4(b), and claims for Losses the validity and amount of which have been the subject of resolution by arbitration or of a final non-appealable judicial determination are hereinafter referred to, collectively, as “Agreed Claims.” The Indemnified Party shall be entitled to payment for any Agreed Claims within ten (10) Business Days of the determination of the amount of any such Agreed Claims.

(a) By virtue of the adoption of this Agreement and the approval of the Merger by the Stockholders, each Stockholder (regardless of whether or not such Stockholder votes in favor of the adoption of the Agreement and the approval of the Merger, whether at a meeting or by written consent in lieu thereof) hereby initially appoints, as of the date of this Agreement, Tim Guleri (together with his permitted successors, the “Stockholder Representative”), as his, her or its true and lawful agent and attorney-in-fact to enter into any agreement in connection with the transactions contemplated by this Agreement and any transactions contemplated by the Escrow Agreement, and to: (i) give and receive notices and communications to or from Parent (on behalf of itself or any other Indemnified Party) and/or the Escrow Agent relating to this Agreement, the Escrow Agreement or any of the transactions and other matters contemplated hereby or thereby (except to the extent that this Agreement or the Escrow Agreement expressly contemplates that any such notice or communication shall be given or received by such Stockholders individually), (ii) authorize deliveries to Parent of cash from (A) the Working Capital Escrow Amount to provide a source of funding to Parent for any Working Capital Deficiency and (B) the Indemnity Escrow Amount in satisfaction of claims asserted by Parent (on behalf of itself or any other Indemnified Party, including by not objecting to such claims), (iii) object to such claims pursuant to Section 10.4, (iv) consent or agree to, negotiate, enter into settlements and compromises of, and agree to arbitration and comply with orders of courts and awards of arbitrators with respect to, such claims, (v) assert, negotiate, enter into settlements and compromises of, and agree to arbitration and comply with orders of courts and awards of arbitrators with respect to, any other claim by any Indemnified Party, against any such Stockholder or by any such Stockholder against any Indemnified Party or any dispute between any Indemnified Party and any such Stockholder, in each case relating to this Agreement, the Escrow Agreement or the transactions contemplated hereby or thereby, (vi) amend this Agreement, the Escrow Agreement or any other agreement referred to herein or contemplated hereby, and (vii) take all actions necessary or appropriate in the judgment of the

Stockholder Representative for the accomplishment of the foregoing, in each case without having to seek or obtain the consent of any Person under any circumstance. The person serving as the Stockholder Representative may be replaced from time to time by the holders of a majority in interest of the Indemnity Escrow Amount upon not less than ten (10) days’ prior written notice to Parent and with Parent’s written consent, which shall not be unreasonably withheld. No bond shall be required of the Stockholder Representative, and the Stockholder Representative shall receive no compensation for his services. Notices or communications to or from the Stockholder Representative shall constitute notice to or from each of the Stockholders.

(b) The Stockholder Representative shall not be liable to any Stockholder for any act done or omitted hereunder as the Stockholder Representative while acting in good faith and any act done or omitted pursuant to the advice of counsel shall be conclusive evidence of such good faith. The Stockholders shall jointly and severally indemnify the Stockholder Representative and hold him harmless against any loss, liability or expense incurred without gross negligence or bad faith on the part of the Stockholder Representative and arising out of or in connection with the acceptance or administration of his duties hereunder. The Stockholder Representative shall be reimbursed for reasonable expenses incurred in the performance of his duties (including, without limitation, the reasonable fees of counsel), and (i) such fees related to costs and charges of the Accounting Referee’s review and report shall be paid out of the Working Capital Escrow Amount and (ii) such other fees shall be paid out of the Indemnity Escrow Amount, pursuant to the terms of the Escrow Agreement.

(c) The Stockholder Representative shall have access to relevant information about the Company and the reasonable assistance of the Company’s officers and the employees for purposes of performing its duties and exercising its rights hereunder; provided, however, that the Stockholder Representative shall treat confidentially and not disclose any nonpublic information from or about the Company to anyone (except on a need to know basis to individuals who agree to treat such information confidentially).

(d) Any notice or communication given or received by, and any decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of, the Stockholder Representative shall constitute a notice or communication to or by, or a decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of all the Stockholders and shall be final, binding and conclusive upon each such Stockholder; and each Indemnified Party and the Escrow Agent shall be entitled to rely upon any such notice, communication, decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction as being a notice or communication to or by, or a decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of, each and every such Stockholder. Except for their gross negligence and willful misconduct, each Indemnified Party and the Escrow Agent are hereby relieved from any liability to any Person for any acts done by them in accordance with any such notice, communication, decision, action, failure to act within a designated period of time, agreement, consent or instruction of the Stockholder Representative.

(e) Except for matters that are subject to Section 10.4, and without limiting the generality or effect of Section 10.5(a), any and all claims and disputes between or among any Indemnified Party, the Stockholder Representative and/or any one or more Stockholders relating to this Agreement or the Escrow Agreement or the transactions contemplated hereby or thereby shall in the case of any claim or dispute asserted by or against or involving any such Stockholder (other than any claim against or dispute with the Stockholder Representative), be asserted or otherwise addressed solely by the Stockholder Representative on behalf of such Stockholder (and not by such Stockholder acting on its own behalf).

10.6 No Subrogation. Following the Closing, no Stockholder shall have any right of indemnification, contribution or subrogation against the Company or any Subsidiary with respect to any indemnification made by or on behalf of any Stockholder under Section 10.2 if the Merger and the transactions contemplated by this Agreement are consummated.

10.7 Purchase Price Adjustment. Amounts required to be paid as indemnification pursuant to this Article 10 shall be treated as adjustments to the purchase price for tax purposes.

No termination of this Agreement shall affect the obligations of the parties contained in the Nondisclosure Agreement, all of which obligations shall survive termination of this Agreement.

(b) In the event that this Agreement is terminated (A) by Parent pursuant to Section 11.1(e) or (B) by the Company pursuant to Section 11.1(g), then the Company shall promptly, but in no event later than the earlier of the date of such termination or date of entrance into an agreement concerning a Superior Proposal or such earlier time as required by this Agreement pay to Parent a cash termination fee of $2,500,000 payable by wire transfer of same day funds (the “Termination Fee”).

(c) In the event that (A) this Agreement is terminated pursuant to Section 11.1(b)(i) after the Company receives a Proposal and (B) within 12 months of such termination the Company enters into an agreement concerning any Proposal, the Company shall at the time of entering into such agreement pay to Parent the Termination Fee payable by wire transfer of same day funds.

(d) The Company and Parent each acknowledge that the agreements contained in Sections 11.2 (b) and (c) are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the Company and Parent would not enter into this Agreement; accordingly, if the Company fails to promptly pay the amounts due pursuant to this Section, and, in order to obtain such payment, Parent commences a suit which results in a judgment against the Company for the fees set forth in this Section 11.2, the Company shall pay to Parent its costs and expenses (including reasonable attorneys’ fees) in connection with such suit, together with interest from the date of termination of this Agreement on the amounts owed at the prime rate of the Bank of America in effect from time to time during such period plus two percent. Provided that the Company has not breached its obligations pursuant to Sections 5.1 and 7.12, the payment of the Termination Fee pursuant to Section 11.2(b) or (c) shall be the sole and exclusive remedy that may be available in law or equity to Parent or Merger Sub for the termination of this Agreement pursuant to Section 11.1(e) or 11.1(g).

11.3 Amendment. Except as is otherwise required by applicable Law, prior to the Closing this Agreement may be amended by the parties hereto at any time by execution of an instrument in writing signed by Parent, Merger Sub and the Company.

VOTING AGREEMENT (this “Agreement”) between Citrix Systems, Inc., a Delaware corporation (“Parent”), Hal Acquisition Corporation, a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”), and the undersigned stockholder (the “Stockholder”) of Net6, Inc., a Delaware corporation (the “Company”).

WHEREAS, the Stockholder owns of record and/or holds (i) shares of the Company’s capital stock and/or (ii) stock options, convertible securities or warrants (whether or not vested) to acquire shares of the Company’s capital stock, in each case in that number and class of shares of the Company’s capital stock set forth on Schedule A hereto (such options, convertible securities, warrants and/or shares of the Company’s capital stock, together with any other such options, convertible securities, warrants and/or shares of capital stock of the Company acquired by such Stockholder after the date hereof and during the term of this Agreement, being collectively referred to herein as the “Subject Shares”);

WHEREAS, upon the fulfillment of the terms and conditions of an Agreement and Plan of Merger by and among Parent, Merger Sub and the Company dated the date hereof (the “Merger Agreement”), the Merger Sub will be merged with and into the Company (the “Merger”);

WHEREAS, the Stockholder believes that the terms of the Merger and the Merger Agreement are fair and that it is in his, her or its best interest as a stockholder of the Company that the Merger be consummated;

WHEREAS, Parent has advised the Company that Parent is not prepared to execute the Merger Agreement unless Parent believes that it is reasonably likely that the Merger will be consummated, and therefore Parent is requiring that certain stockholders undertake in advance to vote their shares in favor of the Merger; and

WHEREAS, for the above reasons, in order to induce Parent to enter into the Merger and in consideration of the execution of the Merger Agreement by Parent and to enhance the likelihood that the Merger will be consummated, the Stockholder, solely in his, her or its capacity as a stockholder of the Company, agrees to vote the Subject Shares so as to facilitate consummation of the Merger.

NOW, THEREFORE, in consideration of the promises and the covenants and agreements set forth below, the parties agree as follows:

1. Definitions. For purposes of this Agreement, terms not defined herein but used herein and defined in the Merger Agreement shall have the meanings set forth in the Merger Agreement.

Transfer. The Stockholder agrees that, during the term of this Agreement, the Stockholder shall not deposit (or permit the deposit of) any Subject Shares in a voting trust or grant any proxy or enter into any voting agreement or similar agreement with respect to any of the Subject Shares or in any way grant any other Person any right whatsoever with respect to the voting or disposition of the Subject Shares. For purposes of this Agreement, a Person shall be deemed to have effected a “Transfer” of a security if such Person directly or indirectly (i) sells, pledges, encumbers, grants an option with respect to, transfers, assigns or otherwise disposes of such security, or any interest in such security; or (ii) enters into an agreement or commitment providing for the sale of, pledge of, encumbrance of, grant of an option with respect to, transfer of or disposition of such security or any interest therein.

4. Director Matters Excluded. Parent and Merger Sub acknowledge and agree that no provision of this Agreement, including without limitation Sections 9 and 12, shall limit or otherwise restrict the Stockholder with respect to any vote, discussions or negotiations that the Stockholder may make or undertake solely in his or her capacity as a director of the Company with respect to a matter presented to the Company’s board of directors.

a. Concurrently with the execution of this Agreement, the Stockholder has executed and delivered to Parent an irrevocable proxy in the form attached hereto as Exhibit A (the “Proxy”), which shall be irrevocable to the fullest extent permissible by law, with respect to the Subject Shares.

d. Each of this Agreement and the Proxy has been duly executed and delivered by the Stockholder, constitutes a valid and binding obligation of the Stockholder and is enforceable against the Stockholder in accordance with its terms.

In the event of the termination of this Agreement, this Agreement and the Proxy shall forthwith

become null and void, there shall be no liability on the part of any of the parties and all rights and obligations of each party hereto shall cease; provided, however, that no such termination of this Agreement shall relieve any party hereto from any liability for any breach of any provision of this Agreement prior to termination.

a. The Stockholder shall not (and (x) if the Stockholder is a corporation, the Stockholder’s board of directors and executive officers shall not authorize, instruct, direct or knowingly allow or (y) if the Stockholder is not a corporation, the Stockholder shall not permit, any of its Affiliates, directors, officers, employees, investment bankers, attorneys or other advisors or representatives, to) (i) directly or indirectly solicit, initiate or knowingly encourage the submission of any Proposal or (ii) subject to Section 4, directly or indirectly participate in any discussions or negotiations regarding, furnish to any Person any information with respect to or take any other action to facilitate any inquiries or the making of any proposal that constitutes, or may reasonably be expected to lead to, a Proposal.

Accordingly, the Stockholder agrees that in the event of any breach or threatened breach of this Agreement, Parent, in addition to any other remedies at law or in equity that it may have, shall be entitled to seek immediate equitable relief, including injunctive relief and specific performance, without the necessity of proving the inadequacy of money damages as a remedy and without the necessity of posting any bond or other security, to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction.

14. Severability. The invalidity or unenforceability of any provision of this Agreement in any jurisdiction shall not affect the validity or enforceability of any other provision of this Agreement in such jurisdiction or the validity or enforceability of any provision of this Agreement in any other jurisdiction.

The Corporation shall indemnify each person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Corporation), by reason of the fact that he is or was, or has agreed to become a director or officer of the Corporation, or is or was serving, or has agreed to serve, at the request of the Corporation, as a director, officer or trustee of, or in a similar capacity with, another corporation,

partnership, joint venture, trust or other enterprise (including any employee benefit plan) (all such persons being referred to hereafter as an “Indemnitee”), or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or on his behalf in connection with such action, suit or proceeding and any appeal therefrom, if he acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in, or not opposed to, the best interests of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful.

if he acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the Corporation, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Corporation unless and only to the extent that the Court of Chancery of Delaware or the court in which such action of suit was brought shall determine upon application that, despite the adjudication of such liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses (including attorneys’ fees) which the Court of Chancery of Delaware of such other court shall deem proper.

3. Indemnification for Expenses of Successful Party. Notwithstanding the other provisions of this Article, to the extent that an Indemnitee has been successful, on the merits or otherwise, in defense of any action, suit or proceeding referred to in Sections 1 and 2 of this Article, or in defense of any claim, issue or matter therein, or on appeal from any such action, suit or proceeding, he shall be indemnified against all expenses (including attorneys’ fees) actually and reasonably incurred by him or on his behalf in connection therewith. Without limiting the foregoing, if any action, suit or proceeding is disposed of, on the merits or otherwise (including a disposition without prejudice), without (i) the disposition being adverse to the Indemnitee, (ii) an adjudication that the Indemnitee was liable to the Corporation, (iii) a plea of guilty or nolo contendere by the Indemnitee, (iv) an adjudication that the Indemnitee did not act in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Corporation, and (v) with respect to any criminal proceeding, an adjudication that the Indemnitee had reasonable cause to believe his conduct was unlawful, the Indemnitee shall be considered for the purpose hereof to have been wholly successful with respect thereto.

4. Notification and Defense of Claim. As a condition precedent to his right to be indemnified, the Indemnitee must notify the Corporation in writing as soon as practicable of any action, suit, proceeding or investigation involving him for which indemnity will or could be sought. With respect to any action, suit, proceeding or investigation of which the Corporation is so notified, the Corporation will be entitled to participate therein at its own expense and/or to assume

the defense thereof at its own expense, with legal counsel reasonably acceptable to the Indemnitee. After notice from the Corporation to the Indemnitee of its election so to assume such defense, the Corporation shall not be liable to the Indemnitee for any legal or other expenses subsequently incurred by the Indemnitee in connection with such claim, other than as provided below in this Section 4. The Indemnitee shall have the right to employ his own counsel in connection with such claim, but the fees and expenses of such counsel incurred after notice from the Corporation of its assumption of the defense thereof shall be at the expense of the Indemnitee unless (i) the employment of counsel by the Indemnitee has been authorized by the Corporation, (ii) counsel to the Indemnitee shall have reasonably concluded that there may be a conflict of interest or position on any significant issue between the Corporation and the Indemnitee in the conduct of the defense of such action or (iii) the Corporation shall not in fact have employed counsel to assume the defense of such action, in each of which cases the fees and expenses of counsel for the Indemnitee shall be at the expense of the Corporation, except as otherwise expressly provided by this Article. The Corporation shall not be entitled, without the consent of the Indemnitee, to assume the defense of any claim brought by or in the right of the Corporation or as to which counsel for the Indemnitee shall have reasonably made the conclusion provided for in clause (ii) above.

5. Advance of Expenses. Subject to the provisions of Section 6 below, in the event that the Corporation does not assume the defense pursuant to Section 4 of this Article of any action, suit, proceeding or investigation of which the Corporation receives notice under this Article, any expenses (including attorneys’ fees) incurred by an Indemnitee in defending a civil or criminal action, suit, proceeding or investigation or any appeal therefrom shall be paid by the Corporation in advance of the final disposition of such matter, provided, however, that the payment of such expenses incurred by an Indemnitee in advance of the final disposition of such matter shall be made only upon receipt of an undertaking by or on behalf of the Indemnitee to repay all amounts so advanced in the event that it shall ultimately be determined that the indemnitee is not entitled to be indemnified by the Corporation as authorized in this Article.

Such undertaking may be accepted without reference to the financial ability of such person to make such repayment.

6. Procedure for Indemnification. In order to obtain indemnification or advancement of expenses pursuant to Section 1, 2, 3 or 5 of this Article, the Indemnitee shall submit to the Corporation a written request, including in such request such documentation and information as is reasonably available to the Indemnitee and is reasonably necessary to determine whether and to what extent the Indemnitee is entitled to indemnification or advancement of expenses. Any such indemnification or advancement of expenses shall be made promptly, and in any event within 60 days after receipt by the Corporation of the written request of the Indemnitee, unless with respect to requests under Section 1, 2 or 5 the Corporation determines, by clear and convincing evidence, within such 60-day period that the Indemnitee did not meet the applicable standard of conduct set forth in Section 1 or 2, as the case may be. Such determination shall be made in each instance by (a) a majority vote of the directors of the Corporation who are not at that time parties to the action, suit or proceeding in question (“disinterested directors”), even though less than a quorum, (b) if there are no such disinterested directors, or if such disinterested directors so direct, by independent legal counsel (who may be regular legal counsel to the corporation) in a written opinion, (c) a majority vote of a quorum of the outstanding shares of stock of all classes entitled to vote for directors, voting as a single class, which quorum shall consist of stockholders who are not at that time parties to the action, suit or proceeding in question, or (d) the Delaware Court of Chancery.

7. Remedies. The right to indemnification or advances as granted by this Article shall be enforceable by the Indemnitee in any court of competent jurisdiction if the Corporation denies such request, in whole or in part, or if no disposition thereof is made within the 60-day period referred to above in Section 6. Unless otherwise provided by law, the burden of proving that the Indemnitee is not entitled to indemnification or advancement of expenses under this Article shall be on the Corporation. Neither the failure of the Corporation to have made a determination prior to the commencement of such action that indemnification is proper in the circumstances

because the Indemnitee has met the applicable standard of conduct, nor an actual determination by the Corporation pursuant to Section 6 that the Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the Indemnitee has not met the applicable standard of conduct. The Indemnitee’s expenses (including attorneys’ fees) incurred in connection with successfully establishing his right to indemnification, in whole or in part, in any such proceeding shall also be indemnified by the Corporation.

8. Subsequent Amendment. No amendment, termination or repeal of this Article or of the relevant provisions of the General Corporation Law of the State of Delaware or any other applicable laws shall affect or diminish in any way the rights of any Indemnitee to indemnification under the provisions hereof with respect to any action, suit, proceeding or investigation arising out of or relating to any actions, transactions or facts occurring prior to the final adoption of such amendment, termination or repeal.

9. Other Rights. The indemnification and advancement of expenses provided by this Article shall not be deemed exclusive of any other rights to which an Indemnitee seeking indemnification or advancement of expenses may be entitled under any law (common or statutory), agreement or vote of stockholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in any other capacity while holding office for the Corporation, and shall continue as to an Indemnitee who has ceased to be a director or officer, and shall inure to the benefit of the estate, heirs, executors and administrators of the Indemnitee. Nothing contained in this Article shall be deemed to prohibit, and the Corporation is specifically authorized to enter into, agreements with officers and directors providing indemnification rights and procedures different from those set forth in this Article. In addition, the Corporation may, to the extent authorized from time to time by its Board of Directors, grant indemnification rights to other employees or agents of the Corporation or other persons serving the Corporation and such rights may be equivalent to, or greater or less than, those set forth in this Article.

10. Partial Indemnification. If an Indemnitee is entitled under any provision of this Article to indemnification by the Corporation for some or a portion of the expenses (including

attorneys’ fees), judgments, fines or amounts paid in settlement actually and reasonably incurred by him or on his behalf in connection with any action, suit, proceeding or investigation and any appeal therefrom but not, however, for the total amount thereof, the Corporation shall nevertheless indemnify the Indemnitee for the portion of such expenses (including attorneys’ fees), judgments, fines or amounts paid in settlement to which the Indemnitee is entitled.

11. Insurance. The Corporation may purchase and maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise (including any employee benefit plan) against any expense, liability or loss incurred by him in any such capacity, or arising out of his status as such, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the General Corporation Law of the State of Delaware.

12. Merger or Consolidation. If the Corporation is merged into or consolidated with another corporation and the Corporation is not the surviving corporation, the surviving corporation shall assume the obligations of the Corporation under this Article with respect to any action, suit, proceeding or investigation arising out of or relating to any actions, transactions or facts occurring prior to the date of such merger or consolidation.

13. Savings Clause. If this Article or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify each Indemnitee as to any expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement in connection with any action, suit, proceeding or investigation, whether civil, criminal or administrative, including an action by or in the right of the Corporation, to the fullest extent permitted by an applicable portion of this Article that shall not have been invalidated and to the fullest extent permitted by applicable law.

14. Definitions. Terms used herein and defined in Section 145(h) and Section 145(i) of the General Corporation Law of the State of Delaware shall have the respective meanings assigned to such terms in such Section 145(h) and Section 145(i).

15. Subsequent Legislation. If the General Corporation Law of the State of Delaware is amended after adoption of this Article to expand further the indemnification permitted to Indemnitees, then the Corporation shall indemnify such persons to the fullest extent permitted by the General Corporation Law of the State of Delaware, as so amended.

EIGHTH. The Corporation reserves the right to amend or repeal any provision contained in this Certificate of Incorporation, in the manner now or hereafter prescribed by statute, and all rights conferred upon a stockholder herein are granted subject to this reservation.

Section 1. Place of Meetings. All meetings of the stockholders may be held at such place within or without the State of Delaware as may be fixed from time to time by the Board of Directors or the Chief Executive Officer, or if not so designated, at the registered office of the Corporation. Notwithstanding the foregoing, the Board of Directors may, in its sole discretion, determine that the meeting shall not be held at any place, but may instead be held solely by means of remote communication as authorized by Section 211(a)(2) of the General Corporation Law of Delaware. If so authorized, and subject to such guidelines and procedures as the Board of Directors may adopt, stockholders and proxyholders not physically present at a meeting of stockholders may, by means of remote communication, participate in a meeting of stockholders whether such meeting is to be held at a designated place or solely by means of remote communication, provided that (i) the Corporation shall implement reasonable measures to verify that each person deemed present and permitted to vote at the meeting by means of remote communication is a stockholder or proxyholder, (ii) the Corporation shall implement reasonable measures to provide such stockholders and proxyholders a reasonable opportunity to participate in the meeting and to vote on matters submitted to the stockholders, including an opportunity to read or hear the proceedings of the meeting substantially concurrently with such proceedings, and (iii) if any stockholder or proxyholder votes or takes other action at the meeting by means of remote communication, a record of such vote or other action shall be maintained by the Corporation.

Section 2. Annual Meeting. Unless directors are elected by written consent in lieu of an annual meeting as permitted by law and these By-Laws, an annual meeting of stockholders may be held at such date and time, and by such means of remote communication, if any, as shall be designated from time to time by the Board of Directors or the Chief Executive Officer, at which meeting the stockholders shall elect by a plurality vote a board of directors and shall transact such other business as may be properly brought before the meeting. If no annual meeting is held in accordance with the foregoing provisions, the Board of Directors shall cause the meeting to be held as soon thereafter as convenient, which meeting shall be designated a special meeting in lieu of annual meeting.

Section 3. Special Meetings. Special meetings of the stockholders, for any purpose or purposes, may, unless otherwise prescribed by statute or by the certificate of incorporation, be called by the Board of Directors or the Chief Executive Officer and shall be called by the Chief

Executive Officer or Secretary at the request in writing of a majority of the Board of Directors, or at the request in writing of stockholders owning a majority in amount of the entire capital stock of the Corporation issued and outstanding and entitled to vote. Such request shall state the purpose or purposes of the proposed meeting. Business transacted at any special meeting shall be limited to matters relating to the purpose or purposes stated in the notice of meeting.

Section 4. Notice of Meetings. Except as otherwise provided by law, written notice of each meeting of stockholders, annual or special, stating the place, date and hour of the meeting, the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such meeting and, in the case of a special meeting, the purpose or purposes for which the meeting is called, shall be given not less than ten (10) nor more than sixty (60) days before the date of the meeting, to each stockholder entitled to vote at such meeting.

Section 5. Voting List. The officer who has charge of the stock ledger of the Corporation shall prepare and make, at least ten (10) days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least ten (10) days prior to the meeting, either (i) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting, or (ii) at the Corporation’s principal place of business. In the event that the Corporation determines to make the list available on an electronic network, the Corporation may take reasonable steps to ensure that such information is available only to stockholders of the Corporation. If the meeting is to be held at a place, then the list shall be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. If the meeting is to be held solely by means of remote communication, then the list shall also be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting.

Section 6. Quorum. The holders of a majority of the stock issued and outstanding and entitled to vote thereat, present in person or by remote communication, or represented by proxy, shall constitute a quorum at all meetings of the stockholders for the transaction of business, except as otherwise provided by statute, the certificate of incorporation or these By-Laws. Where a separate vote by a class or classes is required, one-third of the outstanding shares of such class or classes, present in person or by remote communication, or represented by proxy, shall constitute a quorum entitled to take action with respect to that vote on that matter. If no quorum shall be present or represented at any meeting of stockholders, such meeting may be adjourned in accordance with Section 7 hereof, until a quorum shall be present or represented.

Section 7. Adjournments. Any meeting of stockholders may be adjourned from time to time to any other time and to any other place at which a meeting of stockholders may be held under these By-Laws, which time and place shall be announced at the meeting, by a majority of the stockholders present in person or by remote communication, or represented by proxy at the

meeting and entitled to vote (whether or not a quorum is present), or, if no stockholder is present or represented by proxy, by any officer entitled to preside at or to act as Secretary of such meeting, without notice other than announcement at the meeting. At such adjourned meeting, any business may be transacted which might have been transacted at the original meeting, provided that a quorum either was present at the original meeting or is present at the adjourned meeting. If the adjournment is for more than thirty days, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.

Section 8. Action at Meetings. When a quorum is present at any meeting, the affirmative vote of the holders of a majority of the stock present in person or by remote communication, or represented by proxy, entitled to vote and voting on the matter (or where a separate vote by a class or classes is required, the affirmative vote of the majority of shares of such class or classes present in person or represented by proxy at the meeting) shall decide any matter (other than the election of Directors) brought before such meeting, unless the matter is one upon which by express provision of law, the certificate of incorporation or these By-Laws, a different vote is required, in which case such express provision shall govern and control the decision of such matter. The stock of holders who abstain from voting on any matter shall be deemed not to have been voted on such matter. Directors shall be elected by a plurality of the votes of the shares present in person or by remote communication, or represented by proxy at the meeting, entitled to vote and voting on the election of Directors.

Section 9. Voting and Proxies. Unless otherwise provided in the certificate of incorporation, each stockholder shall at every meeting of the stockholders be entitled to one vote for each share of capital stock having voting power held of record by such stockholder. Each stockholder entitled to vote at a meeting of stockholders, or to express consent or dissent to corporate action in writing without a meeting, may authorize another person or persons to act for him by proxy, but no such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period.

Section 10. Action Without Meeting. Any action required to be taken at any annual or special meeting of stockholders, or any action which may be taken at any annual or special meeting of such stockholders, may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, shall be signed and dated by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted. Prompt notice of the taking of the corporate action without a meeting by less than unanimous written consent shall be given to those stockholders who have not consented in writing. A telegram, cablegram or other electronic transmission consenting to an action to be taken and transmitted by a stockholder or proxyholder, or by a person or persons authorized to act for a stockholder or proxyholder, shall be deemed to be written, signed and dated for the purposes herein, provided that any such telegram, cablegram or other electronic transmission sets forth or is delivered with information from which the Corporation can determine (A) that the telegram, cablegram or other electronic transmission was transmitted by the stockholder or proxyholder or by a person or persons authorized to act for the stockholder or proxyholder and (B) the date on which such stockholder or proxyholder or authorized person or

persons transmitted such telegram, cablegram or other electronic transmission. The date on which such telegram, cablegram or electronic transmission is transmitted shall be deemed to be the date on which such consent was signed. No consent given by telegram, cablegram or electronic transmission shall be deemed to have been delivered until such consent is reproduced in paper form and until such paper form shall be delivered in accordance with Section 228 of the General Corporation Law of Delaware, to the Corporation by delivery to its registered office in Delaware, its principal place of business or an officer or agent of the corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Any copy, facsimile or other reliable reproduction of a consent in writing may be substituted or used in lieu of the original writing for any and all such purposes for which the original writing could be used, provided that such copy, facsimile or other reproduction shall be a complete reproduction of the entire original writing.

Section 1. Number, Election, Tenure and Qualification. The number of Directors which shall constitute the whole board shall be not less than one. Within such limit, the number of Directors shall be determined by resolution of the Board of Directors or by the stockholders at the annual meeting or at any special meeting of stockholders. The directors shall be elected at the annual meeting or at any special meeting of stockholders, or by written consent in lieu of an annual or special meeting of the stockholders (provided, however, that if such consent is less than unanimous, such action by written consent may be in lieu of holding an annual meeting only if all of the directorships to which directors could be elected at an annual meeting held at the effective time of such action are vacant and are filled by such action), except as provided in section 3 of this Article, and each director elected shall hold office until his successor is elected and qualified, unless sooner displaced. Directors need not be stockholders.

Section 2. Enlargement. The number of the Board of Directors may be increased at any time by vote of a majority of the Directors then in office.

Section 3. Vacancies. Vacancies and newly created Directorships resulting from any increase in the authorized number of Directors may be filled by a majority of the Directors then in office, though less than a quorum, or by a sole remaining director, and the Directors so chosen shall hold office until the next annual election and until their successors are duly elected and shall qualify, unless sooner displaced. If there are no Directors in office, then an election of Directors may be held in the manner provided by statute. In the event of a vacancy in the Board of Directors, the remaining Directors, except as otherwise provided by law or these By-Laws, may exercise the powers of the full board until the vacancy is filled.

Section 4. Resignation and Removal. Any director may resign at any time upon notice given in writing or by electronic transmission to the Corporation at its principal place of business or to the Chief Executive Officer or Secretary. Such resignation shall be effective upon receipt unless it is specified to be effective at some other time or upon the happening of some

other event. Any director or the entire Board of Directors may be removed, with or without cause, by the holders of a majority of the shares then entitled to vote at an election of Directors, unless otherwise specified by law or the certificate of incorporation.

Section 5. General Powers. The business and affairs of the Corporation shall be managed by its Board of Directors, which may exercise all powers of the Corporation and do all such lawful acts and things as are not by statute or by the certificate of incorporation or by these By-Laws directed or required to be exercised or done by the stockholders.

Section 6. Chairman of the Board. If the Board of Directors appoints a chairman of the board, he shall, when present, preside at all meetings of the stockholders and the Board of Directors. He shall perform such duties and possess such powers as are customarily vested in the office of the chairman of the board or as may be vested in him by the Board of Directors.

Section 7. Place of Meetings. The Board of Directors may hold meetings, both regular and special, either within or without the State of Delaware.

Section 8. Regular Meetings. Regular meetings of the Board of Directors may be held without notice at such time and at such place as shall from time to time be determined by the board; provided that any director who is absent when such a determination is made shall be given prompt notice of such determination. A regular meeting of the Board of Directors may be held without notice immediately after and at the same place as the annual meeting of stockholders.

Section 9. Special Meetings. Special meetings of the board may be called by the Chief Executive Officer, Secretary, or on the written request of two (2) or more Directors, or by one director in the event that there is only one director in office. Two (2) days’ notice to each director, either personally or by telegram, cable, telecopy, electronic mail, commercial delivery service, telex or similar means sent to his business or home address, or three (3) days’ notice by written notice deposited in the mail, shall be given to each director by the Secretary or by the officer or one of the Directors calling the meeting. A notice or waiver of notice of a meeting of the Board of Directors need not specify the purposes of the meeting.

Section 10. Quorum, Action at Meeting, Adjournments. At all meetings of the board a majority of Directors then in office, but in no event less than one third of the entire board, shall constitute a quorum for the transaction of business and the act of a majority of the Directors present at any meeting at which there is a quorum shall be the act of the Board of Directors, except as may be otherwise specifically provided by law or by the certificate of incorporation. For purposes of this section, the term “entire board” shall mean the number of Directors last fixed by the stockholders or Directors, as the case may be, in accordance with law and these By-Laws; provided, however, that if less than all the number so fixed of Directors were elected, the “entire board” shall mean the greatest number of Directors so elected to hold office at any one time pursuant to such authorization. If a quorum shall not be present at any meeting of the Board of Directors, a majority of the Directors present thereat may adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present.

Section 11. Action by Consent. Unless otherwise restricted by the certificate of incorporation or these By-Laws, any action required or permitted to be taken at any meeting of the Board of Directors or of any committee thereof may be taken without a meeting, if all members of the board or committee, as the case may be, consent thereto in writing or electronic transmission, and the writing or writings or electronic transmission or transmissions are filed with the minutes of proceedings of the board or committee. Such filing shall be in paper form if the minutes are maintained in paper form and shall be in electronic form if the minutes are maintained in electronic form.

Section 12. Telephonic Meetings. Unless otherwise restricted by the certificate of incorporation or these By-Laws, members of the Board of Directors or of any committee thereof may participate in a meeting of the Board of Directors or of any committee, as the case may be, by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and such participation in a meeting shall constitute presence in person at the meeting.

Section 13. Committees. The Board of Directors may designate one or more committees, each committee to consist of one or more of the Directors of the Corporation. The board may designate one or more Directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. Any such committee, to the extent provided in the resolution of the Board of Directors, shall have and may exercise all the powers and authority of the Board of Directors in the management of the business and affairs of the Corporation, and may authorize the seal of the Corporation to be affixed to all papers which may require it; but no such committee shall have the power or authority in reference to (a) adopting, amending or repealing the By-Laws of the Corporation or any of them or (b) approving or adopting, or recommending to the stockholders any action or matter expressly required by law to be submitted to stockholders for approval. Such committee or committees shall have such name or names as may be determined from time to time by resolution adopted by the Board of Directors. Each committee shall keep regular minutes of its meetings and make such reports to the Board of Directors as the Board of Directors may request. Except as the Board of Directors may otherwise determine, any committee may make rules for the conduct of its business, but unless otherwise provided by the Directors or in such rules, its business shall be conducted as nearly as possible in the same manner as is provided in these By-Laws for the conduct of its business by the Board of Directors.

Section 14. Compensation. Unless otherwise restricted by the certificate of incorporation or these By-Laws, the Board of Directors shall have the authority to fix from time to time the compensation of Directors. The Directors may be paid their expenses, if any, of attendance at each meeting of the Board of Directors and the performance of their responsibilities as Directors and may be paid a fixed sum for attendance at each meeting of the Board of Directors and/or a stated salary as director. No such payment shall preclude any director from serving the Corporation or its parent or subsidiary corporations in any other capacity and receiving compensation therefor. The Board of Directors may also allow compensation for members of special or standing committees for service on such committees.

Section 1. Enumeration. The officers of the Corporation shall be chosen by the Board of Directors and shall be a President, a Secretary and a Treasurer and such other officers with such titles, terms of office and duties as the Board of Directors may from time to time determine, including a Chairman of the Board, one or more Vice-Presidents, and one or more Assistant Secretaries and Assistant Treasurers. If authorized by resolution of the Board of Directors, the Chief Executive Officer may be empowered to appoint from time to time Assistant Secretaries and Assistant Treasurers. Any number of offices may be held by the same person, unless the Certificate of Incorporation or these By-Laws otherwise provide.

Section 2. Election. The Board of Directors at its first meeting after each annual meeting of stockholders shall choose a President, a Secretary and a Treasurer. Other officers may be appointed by the Board of Directors at such meeting, at any other meeting, or by written consent.

Section 3. Tenure. The officers of the Corporation shall hold office until their successors are chosen and qualify, unless a different term is specified in the vote choosing or appointing him, or until his earlier death, resignation or removal. Any officer elected or appointed by the Board of Directors or by the Chief Executive Officer may be removed at any time, with or without cause, by the affirmative vote of a majority of the Board of Directors or a committee duly authorized to do so, except that any officer appointed by the Chief Executive Officer may also be removed at any time, with or without cause, by the Chief Executive Officer. Any vacancy occurring in any office of the Corporation may be filled by the Board of Directors, at its discretion. Any officer may resign by delivering his written resignation to the Corporation at its principal place of business or to the Chief Executive Officer or the Secretary. Such resignation shall be effective upon receipt unless it is specified to be effective at some other time or upon the happening of some other event.

Section 4. President. The President shall be the Chief Operating Officer of the Corporation. He shall also be the Chief Executive Officer unless the Board of Directors otherwise provides. If no Chief Executive Officer shall have been appointed by the Board of Directors, all references herein to the “Chief Executive Officer” shall be to the President. The President shall, unless the Board of Directors provides otherwise in a specific instance or generally, preside at all meetings of the stockholders and the Board of Directors, have general and active management of the business of the Corporation and see that all orders and resolutions of the Board of Directors are carried into effect. The President shall execute bonds, mortgages, and other contracts requiring a seal, under the seal of the Corporation, except where required or permitted by law to be otherwise signed and executed and except where the signing and execution thereof shall be expressly delegated by the Board of Directors to some other officer or agent of the Corporation.

Section 5. Vice-Presidents. In the absence of the President or in the event of his or her inability or refusal to act, the Vice-President, or if there be more than one Vice-President, the

Vice-Presidents in the order designated by the Board of Directors or the Chief Executive Officer (or in the absence of any designation, then in the order determined by their tenure in office) shall perform the duties of the President, and when so acting, shall have all the powers of and be subject to all the restrictions upon the President. The Vice-Presidents shall perform such other duties and have such other powers as the Board of Directors or the Chief Executive Officer may from time to time prescribe.

Section 6. Secretary. The Secretary shall have such powers and perform such duties as are incident to the office of Secretary. The Secretary shall maintain a stock ledger and prepare lists of stockholders and their addresses as required and shall be the custodian of corporate records. The Secretary shall attend all meetings of the Board of Directors and all meetings of the stockholders and record all the proceedings of the meetings of the Corporation and of the Board of Directors in a book to be kept for that purpose and shall perform like duties for the standing committees when required. The Secretary shall give, or cause to be given, notice of all meetings of the Stockholders and special meetings of the Board of Directors, and shall perform such other duties as may be from time to time prescribed by the Board of Directors or Chief Executive Officer, under whose supervision the Secretary shall be. The Secretary shall have custody of the corporate seal of the Corporation and the Secretary, or an assistant Secretary, shall have authority to affix the same to any instrument requiring it and when so affixed, it may be attested by his or her signature or by the signature of such assistant Secretary. The Board of Directors may give general authority to any other officer to affix the seal of the Corporation and to attest the affixing by his or her signature.

Section 7. Assistant Secretaries. The assistant Secretary, or if there be more than one, the assistant secretaries in the order determined by the Board of Directors, the Chief Executive Officer or the Secretary (or if there be no such determination, then in the order determined by their tenure in office), shall, in the absence of the Secretary or in the event of his or her inability or refusal to act, perform the duties and exercise the powers of the Secretary and shall perform such other duties and have such other powers as the Board of Directors, the Chief Executive Officer or the Secretary may from time to time prescribe. In the absence of the Secretary or any assistant Secretary at any meeting of stockholders or Directors, the person presiding at the meeting shall designate a temporary or acting Secretary to keep a record of the meeting.

Section 8. Treasurer. The Treasurer shall perform such duties and shall have such powers as may be assigned to him or her by the Board of Directors or the Chief Executive Officer. In addition, the Treasurer shall perform such duties and have such powers as are incident to the office of Treasurer. The Treasurer shall have the custody of the corporate funds and securities and shall keep full and accurate accounts of receipts and disbursements in books belonging to the Corporation and shall deposit all moneys and other valuable effects in the name and to the credit of the Corporation in such depositories as may be designated by the Board of Directors.

Unless written notice by mail is required by law, notice may also be given by telegram, cable, telecopy, commercial delivery service, telex or similar means, addressed to such person at his address as it appears on the records of the corporation, in which case such notice shall be deemed to be given when delivered into the control of the persons charged with effecting such transmission, the transmission charge to be paid by the Corporation or the person sending such notice and not by the addressee.

Subject to principles of best execution, transactions are effected on behalf of the Escrow Accounts through broker-dealers selected by JPMFAM. In this regard, JPMFAM seeks to attain the best overall result for the Escrow Accounts, taking into consideration quality of service and reliability. An agency fee will be assessed in connection with each transaction.

The Escrow Agent shall file such reports and withhold such taxes as it determines is required by law or regulation. It is expressly agreed and understood that the Escrow Accounts shall be treated as grantor trusts of Parent for tax purposes and Parent shall be responsible for filing any applicable tax returns with respect to the interest and other income earned on the Indemnity Escrow Amount and the Working Capital Escrow Amount.

(a) On each occasion on which Parent determines that any Indemnified Party may be entitled to indemnification for any amount pursuant to Article X of the Merger Agreement, Parent may deliver to the Stockholder Representative and the Escrow Agent a Claim Certificate for the payment of such amount pursuant to Section 10.4(a) of the Merger Agreement.

(b) Within thirty (30) days after receipt by the Stockholder Representative of a Claim Certificate, the Stockholder Representative may deliver to Parent and the Escrow Agent a written objection to all or any part of the Claim Certificate (an “Objection”). The Objection shall set forth in detail the basis of the Stockholder Representative’s objection to the Claim Certificate and the amount in dispute.

(c) If the Stockholder Representative fails to deliver an Objection to Parent and the Escrow Agent by 5:00 p.m. Eastern Time on the thirtieth (30th) day following the receipt by the Stockholder Representative of a Claim Certificate, the Escrow Agent shall pay to the Indemnified Parties out of the Indemnity Escrow Account an amount equal to the amount requested in the Claim Certificate (up to a maximum of the Indemnity Escrow Amount). Any such payment shall be made on or before the second (2nd) Business Day following the expiration of such thirty (30)-day period. The Escrow Agent shall continue to hold any amounts remaining in the Indemnity Escrow Account following the payment of any Claim Certificate in accordance with the terms of this Agreement.

(d) If the Stockholder Representative properly delivers a timely Objection with respect to all or any portion of a Claim Certificate, the Escrow Agent shall not disburse, and shall continue to hold in the Indemnity Escrow Account, the amount requested in the Claim Certificate or the disputed portion thereof, as applicable, pending receipt of either (i) payment instructions signed by Parent and the Stockholder Representative, specifying the agreement of

the parties as to the action to be taken by the Escrow Agent in respect of such Claim Certificate (“Joint Payment Instructions”) or (ii) a notice from either Parent or the Stockholder Representative stating that either (A) such Claim Certificate has been submitted to a court of competent jurisdiction for judgment and that a judgment with respect to such matters has been rendered or (B) such Claim Certificate has been submitted to a panel of arbitrators with proper jurisdiction and that a final nonappealable award with respect to such arbitration has been rendered (in each case, a “Judgment Notice”), which Judgment Notice shall be accompanied by a copy of a final, nonappealable order of such court or such arbitration panel, as applicable (each an “Order”), pursuant to which such court or arbitration panel has determined whether and to what extent the Indemnified Parties are entitled to the amount requested in the Claim Certificate. Upon receipt of Joint Payment Instructions or a Judgment Notice, as applicable, the Escrow Agent shall thereafter act in accordance with Section 4(e) or 4(f) below, as applicable. A copy of any Judgment Notice or Order shall be delivered to each party at the same time as it is delivered to the Escrow Agent.

(e) Upon receipt by the Escrow Agent of Joint Payment Instructions, if such Joint Payment Instructions indicate that any Indemnified Parties are entitled to payment in respect of all or any portion of the Claim Certificate, then the Escrow Agent shall release from the Indemnity Escrow Account and pay to the Indemnified Parties the amount indicated in such Joint Payment Instructions (up to a maximum of the Indemnity Escrow Amount). Such payment shall be made on or before the second (2nd) Business Day following the date on which such Joint Payment Instructions are received by the Escrow Agent. If such Joint Payment Instructions indicate that the Indemnified Parties are not entitled to all or any portion of the amount claimed in such Claim Certificate (a “Discharge Notice”), then the Escrow Agent shall continue to hold such amount in the Indemnity Escrow Account in accordance with the terms of this Agreement until such amounts are to be disbursed: (i) to the Payment Agent, pursuant to Sections 4(i) or 4(j), for distribution to the Stockholders in accordance with the Merger Agreement; (ii) to any Indemnified Parties in respect of another Claim Certificate pursuant to Sections 4(c), 4(e) or 4(f), or (iii) to any Person pursuant to Section 4(m).

(f) If the Escrow Agent has received a Judgment Notice with respect to any Claim Certificate, then the Escrow Agent shall release from the Indemnity Escrow Account and pay to the Indemnified Parties an amount equal to the amount due the Indemnified Parties. Such payment shall be made on or before the second (2nd) Business Day following the date on which the Escrow Agent received such Judgment Notice. If the Order accompanying such Judgment Notice indicates that the Indemnified Parties are not entitled to all or any portion of the amount claimed in the Claim Certificate (a “Determination Discharge”), then the Escrow Agent shall continue to hold such amount to which the Indemnified Parties were determined not to be entitled in accordance with the terms of this Agreement until such amounts are to be disbursed: (i) to the Payment Agent, pursuant to Sections 4(i) or 4(j), for distribution to the Stockholders in accordance with the Merger Agreement; (ii) to any Indemnified Parties in respect of another Claim Certificate pursuant to Sections 4(c), 4(e) or 4(f), or (iii) to any Person pursuant to Section 4(m).

(g) (1) Upon receipt by the Escrow Agent of written instructions from Parent on or after the Final Determination Date (“Written Instructions”), if such Written Instructions indicate that the Closing Working Capital is less than the Estimated Working Capital, then the Escrow Agent shall release from the Working Capital Escrow Account and transfer to Parent: (i) an amount in cash equal to the

Working Capital Deficiency; or (ii) if such Written Instructions indicate that the Working Capital Deficiency is greater than the Working Capital Escrow Amount, then the Escrow Agent shall release from the Working Capital Escrow Account and distribute to Parent an amount in cash equal to the entire Working Capital Escrow Amount. Such disbursement shall be made on or before the second (2nd) Business Day following the date on which such Written Instructions are received by the Escrow Agent.

(2) Upon receipt by the Escrow Agent of Written Instructions, if such Written Instructions indicate that the Working Capital Deficiency is greater than the Working Capital Escrow Amount, then the Escrow Agent shall, after releasing the Working Capital Escrow Amount to Parent pursuant to Section 4(g)(1), release from the Indemnity Escrow Account and distribute to Parent the Working Capital Indemnity Amount. Such disbursement shall be made on or before the second (2nd) Business Day following the date on which such Written Instructions are received by the Escrow Agent.

(3) Upon receipt by the Escrow Agent of Written Instructions, if such Written Instructions indicate that the Working Capital Deficiency is less than the Working Capital Escrow Amount, then the Escrow Agent shall release from the Working Capital Escrow Account and disburse to the Payment Agent, after making the disbursement of the Working Capital Deficiency specified in Section 4(g)(1), the balance of the Working Capital Escrow Amount for distribution to the Stockholders in accordance with the Merger Agreement. Such disbursement shall be made on or before the second (2nd) Business Day following the date on which such Written Instructions are received by the Escrow Agent.

(h) Upon receipt by the Escrow Agent of Written Instructions, if such Written Instructions indicate that the Closing Working Capital equals or exceeds the Estimated Working Capital, then the Escrow Agent shall release from the Working Capital Escrow Account and disburse to the Payment Agent the entire Working Capital Escrow Amount for distribution to the Stockholders in accordance with the Merger Agreement. Such disbursement shall be made on or before the second (2nd) Business Day following the date on which such Written Instructions are received by the Escrow Agent.

(i) The twelve (12) month anniversary of the Closing Date is referred to herein as the “Initial Reduction Date.” On the Initial Reduction Date, the Indemnity Escrow Amount shall automatically be reduced by an amount equal to the excess (if any) of (x) the balance of the Indemnity Escrow Amount on the Initial Reduction Date over (y) $1,500,000 (such excess being referred to as the “Initial Indemnity Escrow Disbursement”). On or before the second (2^nd) Business Day following the receipt of Joint Written Instructions by the Escrow Agent notifying the Escrow Agent of the Initial Reduction Date, subject to the provisions of the following sentence, the Escrow Agent shall pay to the Payment Agent the Initial Indemnity Escrow Disbursement for distribution to the Stockholders in accordance with the Merger Agreement. If, however, the Escrow Agent shall have received on or before the Initial Reduction Date one or more Claim Certificates that have not been paid in accordance with Section 4(c) as of the Initial Reduction Date and as to which, on the Initial Reduction Date, the Escrow Agent has not received and fully acted upon Joint Payment Instructions or a Judgment Notice, nor received a Discharge Notice or a Determination Discharge (any such Claim Certificate being referred to as an “Initial Outstanding Claim”), the Escrow Agent shall retain and continue to hold in accordance with the terms hereof an amount equal to the amount requested in all such Initial Outstanding Claims (the “Initial Retained Amount”) but shall pay to the Payment Agent an

amount equal to the excess, if any, of the Initial Indemnity Escrow Disbursement over the Initial Retained Amount for distribution to the Stockholders in accordance with the Merger Agreement; and, thereafter, the Escrow Agent shall release from the Indemnity Escrow Account all or portions of the Initial Retained Amount to Parent and/or the Payment Agent for distribution to the Stockholders in accordance with the Merger Agreement, as applicable, as and when it receives Joint Payment Instructions, Judgment Notices, Discharge Notices or Determination Discharges, as applicable, related to the Initial Outstanding Claims. Following the Initial Reduction Date, in the event that the Initial Retained Amount at any time exceeds the amount of all Initial Outstanding Claims that have not been paid to the Indemnified Parties or that are not subject to a Discharge Notice or Determination Discharge, the Escrow Agent shall pay to the Payment Agent within five (5) Business Days of the Stockholder Representative’s written request for such payment, an amount equal to such excess for distribution to the Stockholders in accordance with the Merger Agreement. The balance of the Indemnity Escrow Amount shall be held in escrow to fund claims for indemnification by any Indemnified Party pursuant to Article X of the Merger Agreement.

(j) The twenty-four (24)-month anniversary of the Closing Date is referred to herein as the “Final Reduction Date.” On the Final Reduction Date, the Indemnity Escrow Amount shall be reduced by an amount equal to the excess (if any) of (x) the balance of the Indemnity Escrow Amount on the Final Reduction Date over (y) the portion of the Initial Retained Amount not previously disbursed as provided in Section 4(i) hereof (the “Final Disbursement Amount”).

If, however, the Escrow Agent shall have received on or before the Final Reduction Date one or more Claim Certificates that have not been paid in accordance with Section 4(c) as of the Final Reduction Date and that were not included in determining the Initial Retained Amount and as to which, on the Final Reduction Date, the Escrow Agent has not received and fully acted upon Joint Payment Instructions or a Judgment Notice, nor received a Discharge Notice or a Determination Discharge (all such Claim Certificates, together with the Initial Outstanding Claims, the “Final Outstanding Claims”), the Escrow Agent shall retain and continue to hold in accordance with the terms hereof an amount equal to the amount requested in all such Final Outstanding Claims (all such amounts, together with any portion of the Initial Retained Amount not previously disbursed as provided in Section 4(i), the “Final Retained Amount”) but shall pay to the Payment Agent an amount equal to the excess, if any, of the Final Disbursement Amount over the Final Retained Amount for distribution to the Stockholders in accordance with the Merger Agreement; and, thereafter, the Escrow Agent shall release from the Indemnity Escrow Account to Parent and/or the Payment Agent for distribution to the Stockholders in accordance with the Merger Agreement, as applicable, all or portions of the Final Retained Amount as and when it receives Joint Payment Instructions, Judgment Notices, Discharge Notices or Determination Discharges, as applicable, related to the Final Outstanding Claims. Following the Final Reduction Date, in the event that the Final Retained Amount at anytime exceeds the amount of all Final Outstanding Claims that have not been paid to the Indemnified Parties or that are not subject to a Discharge Notice or Determination Discharge, the Escrow Agent shall pay to the Payment Agent within

two (2) Business Days of the Stockholder Representative’s written request for such payment, an amount equal to such excess for distribution to the Stockholders in accordance with the Merger Agreement.

(k) Upon receipt of written instructions signed by the Stockholder Representative indicating that the Stockholder Representative has incurred reasonable expenses in connection with the performance of its duties under this Agreement or the Merger Agreement, the Escrow Agent shall promptly reimburse the Stockholder Representative for the amount of (i) any reasonable expenses related to costs and charges of the Accounting Referee’s review and report, from the Working Capital Escrow Account and (ii) any other reasonable expenses, from the Indemnity Escrow Account.

The parties will cooperate in good faith in executing such Joint Written Instructions whenever reasonably necessary to ensure distributions of escrowed funds to the party entitled thereto under the terms of the Merger Agreement.

In addition, if the Escrow Agent should at any time be confronted with inconsistent claims or demands by the parties hereto, the Escrow Agent shall also have the right to interplead such parties in any state or federal court located in the State of Delaware (or if such court does not have jurisdiction, any other court of competent jurisdiction), to deposit the Indemnity Escrow Amount and the Working Capital Escrow Amount with the clerk of such court and to request that such court determine the respective rights of the parties under this Agreement, and, upon doing so, the Escrow Agent automatically shall be released from any obligations or liability as a consequence of any claims or demands hereunder.

The Stockholders and Parent shall jointly and severally indemnify, defend and save harmless the Escrow Agent and its directors, officers, agents and employees (the “Indemnitees”) from all loss, liability or expense (including the fees and expenses of legal counsel) arising out of or in connection with (i) the Escrow Agent’s execution and performance of this Agreement, except in the case of any Indemnitee to the extent that such loss, liability or expense is due to the gross negligence or willful misconduct of such Indemnitee or (ii) the Escrow Agent following any instructions or other directions from Parent and the Stockholder Representative, except to the extent that following any such instruction or direction is expressly forbidden by the terms of this Agreement. The parties hereto acknowledge that the foregoing indemnities shall survive the resignation or removal of the Escrow Agent or the termination of this Agreement.

7. Resignation of the Escrow Agent; Acquisition of the Escrow Agent. The Escrow Agent, and any successor Escrow Agent, may resign at any time as the Escrow Agent hereunder by giving at least fifteen (15) Business Days written notice to the parties. Upon such resignation and the appointment of a successor Escrow Agent, the resigning Escrow Agent shall be absolved from any further duties as the Escrow Agent hereunder. Upon their receipt of notice of resignation from the Escrow Agent, Parent and the Stockholder Representative shall use their reasonable best efforts jointly to designate a successor Escrow Agent. If Parent and the Stockholder Representative do not agree upon a successor Escrow Agent within fifteen (15) Business Days after the receipt by the parties of the Escrow Agent’s resignation notice, the Escrow Agent may petition any court of competent jurisdiction for the appointment of a successor Escrow Agent or other appropriate relief and any such resulting appointment shall be binding upon all parties hereto. By mutual agreement, Parent and the Stockholder Representative shall have the right at any time upon not less than seven (7) Business Days written notice to terminate their appointment of the Escrow Agent, or any successor Escrow Agent, as the Escrow Agent hereunder. Notwithstanding anything to the contrary in the foregoing, the Escrow Agent or any successor Escrow Agent shall continue to act as the Escrow Agent until a successor is appointed and qualified to act as the Escrow Agent.

Any corporation or association into which the Escrow Agent may be merged or converted or with which it may be consolidated, or any corporation or association to which all or substantially all of the escrow business of the Escrow Agent’s corporate trust line of business may be transferred, shall be the Escrow Agent under this Agreement without further act, and the Escrow Agent shall notify the other parties hereto of such occurrence.

8. Fees and Expenses of the Escrow Agent. The fees and the expenses of the Escrow Agent for its services hereunder shall be paid by Parent in accordance with Schedule 3. The provisions of this Section 8 shall survive any termination of this Agreement and removal or resignation of the Escrow Agent.

9. Notices. All notices and other communications required or permitted pursuant to this Agreement shall be in writing and addressed to such party for whom such communication is intended at the applicable address set forth below. Such notice shall be deemed to have been duly given (i), with regard to the Escrow Agent, when actually received by the Escrow Agent and (ii), with regard to any other party hereto, when delivered personally (which shall include

delivery by Federal Express or other nationally recognized, reputable overnight courier service that issues a receipt or other confirmation of delivery) to the party for whom such communication is intended or two (2) Business Days after the date mailed by certified mail, return receipt requested, postage prepaid, as follows:

or to such other address as such party shall specify by written notice to the other parties hereto. Any notice sent to the Escrow Agent shall also be sent to the other parties to this Agreement.

10. Assignment. Parent may assign its rights and obligations under this Agreement to the same extent it is permitted to assign its rights and obligations under the Merger Agreement.

11. Security Procedures. In the event funds transfer instructions are given (other than in writing at the time of execution of this Agreement), whether in writing, by telecopier or otherwise, the Escrow Agent is authorized to seek confirmation of such instructions by telephone call-back to the person or persons designated on Schedule 4, and the Escrow Agent may rely upon the confirmation of anyone purporting to be the person or persons so designated. The persons and telephone numbers for call-backs may be changed only in a writing actually received and acknowledged by the Escrow Agent. The Escrow Agent and the beneficiary’s bank in any funds transfer may rely solely upon any account numbers or similar identifying numbers provided by Parent or the Stockholder Representative to identify (i) the beneficiary, (ii) the beneficiary’s bank or (iii) an intermediary bank. The Escrow Agent may apply any of the escrowed funds for any payment order it executes using any such identifying number, even when its use may result in a person other than the beneficiary being paid, or the transfer of funds to a bank other than the beneficiary’s bank or an intermediary bank designated. The parties to this Escrow Agreement acknowledge that these security procedures are commercially reasonable.

12. Miscellaneous. This Agreement and, with respect to Parent, the Company and the Stockholder Representative, the Merger Agreement embody the entire agreement and understanding of the parties concerning the Indemnity Escrow Amount and the Working Capital Escrow Amount and, in the event of any inconsistency between this Agreement and the Merger Agreement, this Agreement shall control. This Agreement may be amended only by a writing signed by the party against whom enforcement is sought. The headings in this Agreement are intended solely for convenience or reference and shall be given no effect in the construction or interpretation of this Agreement. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, except the choice of law rules utilized in that state. This Agreement shall bind and inure to the benefit of the parties hereto and their respective, heirs, personal representatives, successors and permitted assigns. Each party hereto irrevocably waives any objection on the grounds of venue, forum non-conveniens or any similar grounds, irrevocably consents to service of process by mail or in any other manner permitted by applicable law and consents to the jurisdiction of the courts located in the State of Delaware. The parties further hereby waive any right to a trial by jury with respect to any lawsuit or judicial

proceeding arising out of or relating to this Agreement. The Escrow Agent shall not be liable to any other party for losses due to, or if it is unable to perform its obligations under the terms of this Agreement because of, acts of God, fire, floods, strikes, equipment or transmission failure or other causes reasonably beyond its control. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and same instrument. All signatures of the parties to this Agreement may be transmitted by facsimile, and such facsimile will, for all purposes, be deemed to be the original signature of such party whose signature it reproduces and will be binding upon such party.

To evidence their agreement, the parties have caused this Agreement to be executed on the date first written above.
