In the event Parent does not deliver the Closing Balance Sheet and Closing Statement to the Equityholders’ Representative within sixty (60) days following the Closing Date, the Estimated Balance Sheet and Estimated Closing Statement shall be deemed to be final and binding on the Parties and the Estimated Closing Statement shall be deemed to be the Final Closing Statement for all purposes hereunder.

(c) Notice of Disagreement. The Closing Statement shall become final and binding upon the Parties on the date (the “Final Settlement Date”) that is forty-five (45) days following receipt thereof by the Equityholders’ Representative unless the Equityholders’ Representative gives written notice of its disagreement (“Notice of Disagreement”) to Parent prior to such date. Any Notice of Disagreement shall specify in reasonable detail the dollar amount, nature and basis of any disagreement so asserted and any portion of the Closing Statement not subject to any disagreement shall be deemed to be final as set forth in the Closing Statement. If a Notice of Disagreement is received by Parent in a timely manner, then the Closing Statement (as revised in accordance with Section 2.7(d) below, if applicable) shall become final and binding on the Parties on, and the Final Settlement Date shall be, the earlier of (i) the date upon which the Equityholders’ Representative and Parent agree in writing with respect to all matters specified in the Notice of Disagreement and (ii) the date upon which the Final Closing Statement is issued by the Arbitrator.

(d) Final Closing Statement. During the first twenty (20) days following the date upon which Parent receives a Notice of Disagreement, the Equityholders’ Representative and Parent shall attempt in good faith to resolve in writing any differences that they may have with respect to all matters specified in the Notice of Disagreement. If at the end of such twenty (20) day period (or earlier by mutual agreement to arbitrate) Parent and the Equityholders’ Representative have not reached agreement on such matters, the matters that remain in dispute may be submitted to Grant Thornton LLP (the “Arbitrator”) by either Party for review and resolution. If Grant Thornton LLP is unable to serve as the “Arbitrator” hereunder, the Arbitrator shall be a internationally recognized independent public accounting firm agreed upon by Parent and the Equityholders’ Representative in writing. As promptly as practicable (but in no event more than thirty (30) days) after the retention of the Arbitrator, Parent and the Equityholders’ Representative shall each prepare and submit a presentation to the Arbitrator. As soon as practicable (but in no event more than thirty (30) days) thereafter, the Arbitrator shall determine the amount of each item in dispute and prepare a Final Closing Statement and calculation of Working Capital, Closing Date Indebtedness and Closing Date Cash in accordance with the principles in this Section 2.7, which shall include an explanation in writing of the Arbitrator’s reasons for the determinations set forth therein. The Arbitrator shall act as an arbitrator and shall address only those items in dispute and for each item may not assign a value greater than the greatest value for such item claimed by either Party or smaller than the smallest value for such item claimed by either Party. The decision of the Arbitrator shall be final and binding on the Parties. The costs, fees and expenses of the Arbitrator in connection with the Arbitrator’s review pursuant to this Section 2.7(d) (including reasonable attorney’s fees of the Arbitrator) shall be borne fifty percent (50%) by Parent and fifty percent (50%) by the Equityholders out of the Equityholders’ Representative Escrow Account. Each of Parent and the Equityholders’ Representative shall pay its own costs, fees and expenses (including attorney’s fees) in connection with the Arbitrator’s review pursuant to this Section 2.7(d), without right of reimbursement from such other Party; provided, that such costs, fees and expenses of the Equityholders’ Representative (up to a maximum of one million dollars ($1,000,000)), including any amounts payable to the Arbitrator out of the Equityholders’ Representative Escrow Account pursuant to the previous sentence) shall be paid out of the Equityholders’ Representative Escrow Account.

(e) Final Settlement and Adjustment to Total Cash Equity Price.

(i) (A) If the Adjustment Amount as derived from the Final Closing Statement is a negative number, then the Total Cash Equity Price shall be decreased by an amount, not to exceed the amount held in the General Escrow Account, equal to such Adjustment Amount as derived from the Final Closing Statement (“Shortfall Reduction”) and (B) if the Adjustment Amount as derived from the Final Closing Statement is a positive number, then the Total Cash Equity Price shall be increased by an amount equal to such Adjustment Amount (“Excess Payment”).

(ii) Any Shortfall Reduction or Excess Payment described in clause (A) or (B) in Section 2.7(e)(i) shall be paid not later than three (3) Business Days after the Final Settlement Date (1) in the case of an Excess Payment, by Parent by wire transfer of immediately available funds to the Exchange Agent to be added to the Exchange Fund for the benefit of, and to be distributed to, the Equityholders in accordance with Section 3.1, or (2) in the case of a Shortfall Reduction, out of the General Escrow Account by the Equityholders’ Representative and Parent sending a joint written instruction to the Escrow Agent to disburse funds in the amount of the Shortfall Reduction out of the General Escrow Account to Parent; provided, that the amount of any such payment shall not exceed the General Escrow Amount.

(f) Cooperation. For the purposes of complying with the terms set forth in this Section 2.7, each Party shall cooperate with and make available to the other Parties and their respective representatives all information, records, data and working papers, and shall permit access to its facilities and personnel, as may reasonably be required in connection with the preparation and analysis of the Closing Balance Sheet and Closing Statement and the resolution of any disputes related thereto.

(g) Adjustment to Total Cash Equity Price. Any Shortfall Reduction payable pursuant to this Section 2.7 shall be deemed to be an adjustment to the Total Cash Equity Price.

SECTION 2.8 Payment of Company Transaction Expenses; Pro-Rata Bonuses. At or prior to the Closing, the Company shall pay (x) the Company Transaction Expenses and (y) the Management Retention Bonuses to each Company Employee eligible under the Management Retention Bonus Plan, as determined in accordance with the Management Retention Bonus Plan by the Company. Within five (5) Business Days after Closing, the Surviving Corporation shall pay to each Company Employee eligible to receive an annual bonus pursuant to the Annual Bonus Program a pro-rata annual bonus (“Pro-Rata Bonus”) in an amount equal to the product of (i) the Company Employee’s target annual bonus under the Annual Bonus Program with respect to the fiscal year in which the Closing occurs and (ii) the ratio of (A) the number of days elapsed during the period beginning on the first day of the Company’s fiscal year in which the Closing occurs and ending on the Closing Date to (B) 365.

SECTION 2.9 Calculations and Iterative Process.

(a) Section 2.9 of the Company Disclosure Schedule sets forth for illustrative purposes a sample calculation of the allocation of the Merger Consideration, Option Payments and Warrant Payments among the Equityholders that gives effect to the provisions of this Agreement based on the assumptions set forth therein. Such calculation shall use an iterative process (the “Iterative Process”) to determine which Company Options and Warrants are “in-the-money” based on the applicable exercise price of the Company Options and Warrants in conjunction with the calculation of the following amounts and definitions: Common Merger Consideration, Common Per-Share Merger Consideration, Fully-Diluted Common Stock, Merger Consideration, Option In-the-Money Amount, Common Warrant In-the-Money Amount, Series B Warrant In-the-Money Amount, Series C Warrant In-the-Money Amount, Series C-1 Warrant In-the-Money Amount, Series A Preferred Per-Share Merger Consideration, Series B Preferred Per-Share Merger Consideration, Series C Preferred Per-Share Merger Consideration, Series C-1 Preferred Per-Share Merger Consideration, Total Common Merger Consideration, Total Series A Preferred Merger Consideration, Total Series A Preferred Merger Preference, Total Series B Preferred Merger Consideration, Total Series B Preferred Merger Preference, Total Series C Preferred Merger Consideration, Total Series C Preferred Merger Preference, Total Series C-1 Preferred Merger Consideration, and Total Series C-1 Preferred Merger Preference.

(b) For the avoidance of doubt, the aggregate amounts payable by Parent or the Surviving Corporation under this Agreement in respect of Company Capital Stock, Company Options and Warrants shall equal (and not exceed) the Estimated Total Cash Equity Price plus any Excess Payment plus funds released from time to time from the General Escrow Account or the Equityholders’ Representative Escrow Account to the Equityholders.

ARTICLE III.

EXCHANGE OF COMPANY CERTIFICATES

SECTION 3.1 Exchange of Company Certificates.

(a) Exchange Agent. At or prior to the Effective Time, and subject to Section 3.1(c), Parent shall deposit, or shall cause to be deposited, (i) with JPMorgan Chase Bank, N.A., or another bank or trust company designated by Parent and reasonably satisfactory to the Company (the “Exchange Agent”), for the benefit of the holders of shares of Company Capital Stock and Warrants, cash in U.S. dollars in an amount equal to the Estimated Total Cash Equity Price less an amount equal to the Closing Option Payments (such cash, together with any Excess Payment (and interest thereon) being hereinafter referred to as the “Exchange Fund”), (ii) with the Escrow Agent, the General Escrow Amount to the General Escrow Account and the Equityholders’ Representative Escrow Amount to the Equityholders’ Representative Escrow Account, and (iii) with the Surviving Corporation, the amount equal to the Closing Option Payments. The Exchange Agent shall, pursuant to irrevocable instructions from the Company, deliver the Merger Consideration and the Warrant Payments contemplated to be paid pursuant to, and in accordance with the terms of, Section 2.6 and this Article III out of the Exchange Fund. The Exchange Fund shall not be used for any other purpose. Notwithstanding anything else in Article II or this Article III to the contrary, payment of Merger Consideration and the Warrant Payments may be made in installments as necessary to take into account any adjustments to the Total Cash Equity Price pursuant to Section 2.7, and any Excess Payment.

(b) Exchange Procedures. Subject to Section 3.1(c), promptly following the Effective Time (but in no event later than two (2) Business Days following the Effective Time), Parent shall instruct the Exchange Agent to mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Company Capital Stock or Warrants (the “Certificates”) (A) a letter of transmittal substantially in the form attached hereto as Exhibit C (“Letter of Transmittal”), which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent and shall be in customary form reasonably satisfactory to Parent and the Equityholders’ Representative, and (B) instructions for use in effecting the surrender of the Certificates in exchange for the portion of the Merger Consideration or Warrant Payment (as applicable) receivable in respect of such Certificates. Upon surrender of a Certificate for cancellation to the Exchange Agent together with such Letter of Transmittal, properly completed and duly executed, and such other documents as may be required pursuant to such instructions, the holder of such Certificate shall be entitled to receive in exchange therefor the portion of the Merger Consideration or Warrant Payment (as applicable) which such holder has the right to receive in respect of the shares of Company Capital Stock or Warrants formerly represented by such Certificate (and the right to receive payments from the General Escrow Account and the Equityholders’ Representative Escrow Account in accordance with the Escrow Agreement and Section 3.3), and the Certificate so surrendered shall forthwith be canceled. Following any receipt of an Excess Payment, the Exchange Agent will deliver to each holder of surrendered Certificates, such holder’s pro rata portion thereof; provided, that if the Exchange Agent receives an Excess Payment prior to receipt of surrendered Certificates, then payment of the portion thereof applicable to such unsurrendered Certificates shall be made at the same time as payment of the balance of the applicable Merger Consideration or Warrant

Payment (as applicable) upon surrender thereof. No interest will be paid or accrued on any Merger Consideration or Warrant Payment (as applicable) payable to holders of Certificates. In the event of a transfer of ownership of shares of Company Capital Stock or Warrants that is not registered in the transfer records of the Company, the portion of the Merger Consideration or Warrant Payment (as applicable) payable in respect of such shares of Company Capital Stock or Warrants may be issued to a transferee if the Certificate representing such shares of Company Capital Stock or Warrants is presented to the Exchange Agent, accompanied by any documents reasonably required to evidence and effect such transfer and by evidence that any applicable stock transfer Taxes have been paid. Until surrendered as contemplated by this Section 3.1, each Certificate shall, subject to Section 3.2, be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the portion of the Merger Consideration or Warrant Payment (as applicable) payable in respect of such Certificate as set forth in Section 2.6.

(c) Exchange at Closing. Notwithstanding Section 3.1(b), each holder of a Certificate, upon surrender thereof to the Exchange Agent at the Closing together with a Letter of Transmittal (properly completed and duly executed) and any other required documents of transfer, and provided such holder has provided Parent and the Exchange Agent with at least five (5) Business Days’ written notice of its intention to so surrender its Certificates, shall be entitled to receive at or immediately after the Closing in exchange therefor the portion of the Merger Consideration or Warrant Payment (as applicable) which such holder has the right to receive in respect of the shares of Company Capital Stock or Warrants formerly represented by such Certificates (and shall also be entitled to the right to receive payments from the General Escrow Account and the Equityholders’ Representative Escrow Account in accordance with the Escrow Agreement and Section 3.3). Promptly following such surrender, the Exchange Agent shall deliver the portion of the Merger Consideration or Warrant Payment (as applicable) payable out of the Exchange Fund in respect of such surrendered Certificates.

(d) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of Company Capital Stock and Warrants as of the earlier to occur of (i) one (1) month after the Final Settlement Date and (ii) one (1) year after the Effective Time shall be delivered to Parent upon demand, and any holders of Company Capital Stock and Warrants who have not theretofore complied with this Article III shall thereafter look only to Parent for the Merger Consideration or Warrant Payments.

(e) No Liability. No Party shall be liable to any holder of shares of Company Capital Stock or Warrants for any cash from the Exchange Fund or other amount delivered to a public official pursuant to any abandoned property, escheat or similar Law.

(f) Lost or Missing Certificates. If any Certificate shall have been lost, stolen or destroyed or shall otherwise be missing, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen, destroyed or missing and, if required by Parent, the execution and delivery by such Person of an indemnity agreement against any claim that may be made against the Exchange Agent with respect to such Certificate in customary form and substance reasonably satisfactory to Parent, the Exchange Agent will deliver in exchange for such lost, stolen, destroyed or missing Certificate, the portion of the Merger Consideration or Warrant Payment (as applicable) payable in respect of such lost, stolen, destroyed or missing Certificate (and such Person shall have the right to receive payments from the General Escrow Account and the Equityholders’ Representative Escrow Account in accordance with the Escrow Agreement and Section 3.3).

(g) Withholding. Parent, the Surviving Corporation, the Exchange Agent and the Escrow Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant

to this Agreement or the Escrow Agreement to any holder of Company Capital Stock, Company Options or Warrants such amounts as Parent, the Surviving Corporation, the Exchange Agent and the Escrow Agent are required to deduct and withhold under the Code, or any provision of state, local or foreign tax Law, with respect to the making of such payment. To the extent that amounts are so withheld by Parent, the Surviving Corporation, Exchange Agent or the Escrow Agent and timely paid over to the applicable Government Authority, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Company Capital Stock, Company Options or Warrants in respect of whom such deduction and withholding was made by Parent, the Surviving Corporation, the Exchange Agent or the Escrow Agent.

SECTION 3.2 Appraisal Rights. Notwithstanding anything in this Agreement to the contrary, if any Dissenting Stockholder shall demand to be paid the “fair value” of such Dissenting Stockholder’s shares of Company Capital Stock, as provided in Section 262 of the DGCL, such shares of Company Capital Stock shall not be converted into or exchangeable for the right to receive any portion of the Merger Consideration (except as provided in this Section 3.2) and shall entitle such Dissenting Stockholder only to payment of the fair value of such shares of Company Capital Stock, in accordance with Section 262 of the DGCL, unless and until such Dissenting Stockholder withdraws (in accordance with Section 262(k) of the DGCL) or effectively loses the right to dissent. Neither the Company nor the Surviving Corporation shall, except with the prior written consent of Parent, voluntarily make any payment with respect to, or settle or offer to settle, any such demand for payment of fair value of a Dissenting Stockholder’s shares of Company Capital Stock and the Company shall give Parent notice thereof and Parent shall have the right to participate at its own expense in all negotiations and proceedings with respect to any such demands. If any Dissenting Stockholder shall have effectively withdrawn (in accordance with Section 262(k) of the DGCL) or lost the right to dissent, then as of the later of the Effective Time or the occurrence of such event, the shares of Company Capital Stock held by such Dissenting Stockholder shall be converted into and represent the right to receive the applicable portion of the Merger Consideration pursuant to Section 2.6.

SECTION 3.3 Escrow. The General Escrow Amount shall be delivered to the Escrow Agent at or prior to the Effective Time to be held in escrow as security for the payment of any Shortfall Reduction under Section 2.7(e) and indemnification claims under Article IX pursuant to the provisions of the Escrow Agreement. The Equityholders’ Representative Escrow Amount delivered to the Escrow Agent shall be deposited in a separate account (the “Equityholders’ Representative Escrow Account”) to be held in escrow to fund the out-of-pocket costs and expenses of the Equityholders’ Representative pursuant to the provisions of the Escrow Agreement. Within five (5) Business Days of the Escrow Termination Date, except as otherwise provided in the Escrow Agreement with respect to outstanding claims and the Investment Income Tax Amount (as defined in the Escrow Agreement), each of Parent and the Equityholders’ Representative shall execute joint written instructions to the Escrow Agent instructing the Escrow Agent to disburse to the holders of Company Capital Stock and Warrants and to the Surviving Corporation (for distribution of Option Payments to the holders of Company Options) their respective pro rata portions of the balance of the Escrow Amount, together with any earnings thereon pursuant to the Escrow Agreement, less any amounts owing to the Equityholders’ Representative.

SECTION 3.4 No Further Ownership Rights in Shares of Company Capital Stock; Closing of Company Transfer Books. At and after the Effective Time, each holder of Company Capital Stock shall cease to have any rights as a stockholder of the Company, except for, in the case of a holder of Company Capital Stock (other than shares to be cancelled pursuant to Section 2.6(b)), the right to surrender his or her Certificate in exchange for payment of the applicable Merger Consideration or, in the case of a Dissenting Stockholder, to perfect his or her right to receive payment for his or her shares of Company Capital Stock pursuant to the DGCL. At the Effective Time, the stock transfer books

of the Company shall be closed, and no transfer of shares of Company Capital Stock shall thereafter be made. If, after the Effective Time, Certificates are presented to the Surviving Corporation, they shall be cancelled and exchanged as provided for in this Agreement.

(d) From and after the Effective Time, for the purposes of determining eligibility to participate, vesting and entitlement to benefits where length of service is relevant under any benefit plan or arrangement of Parent, the Surviving Corporation or any of their respective Affiliates, Parent shall, and shall cause the Surviving Corporation to, cause each Continuing Employee to receive service credit for service with the Company to the same extent such service credit was granted under the Company Benefit Plans (other than for the purposes of benefit accrual under a defined benefit plan) immediately prior to the Effective Time. Parent shall, and shall cause the Surviving Corporation to (i) waive all limitations as to preexisting conditions exclusions and waiting periods with respect to participation and coverage requirements applicable to the Company Employees (and any dependents or beneficiaries thereof) under any welfare benefit plans that such employees may be eligible to participate in after the Effective Time,

other than limitations or waiting periods that are already in effect with respect to such employees and that have not been satisfied as of the Effective Time under any welfare benefit plan maintained for the Company Employees immediately prior to the Effective Time and (ii) use commercially reasonable efforts to provide each Company Employee with credit for any co-payments and deductibles paid prior to the Effective Time in satisfying any applicable deductible or out-of-pocket requirements under any welfare plans that such employees are eligible to participate in after the Effective Time.

Equityholders’ Representative (with a copy to the Escrow Agent) in the case of an indemnification claim pursuant to Section 9.2(a) against the Equityholders) (the “Indemnifying Party”) of the assertion of any claim or the commencement of any Action by any third party (a “Third Party Claim”) in respect of which indemnity may be sought under such section. Such notice shall set forth in reasonable detail such Third Party Claim and the basis for indemnification (taking into account the information then available to the Indemnified Party). The failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent such failure shall have materially and adversely prejudiced the Indemnifying Party.

(b) The Indemnifying Party shall be entitled to participate in the defense of any Third Party Claim and, subject to the limitations set forth in this Section 9.6, shall be entitled to control and appoint lead counsel for such defense, in each case at its own expense; provided, that prior to assuming control of such defense, the Indemnifying Party must (i) acknowledge that, if the facts as alleged by the claimant in the Third Party Claim are true, it would have an indemnity obligation for the Damages resulting from such Third Party Claim as provided under this Article IX and (ii) must furnish the Indemnified Party with reasonable evidence that the Indemnifying Party has adequate resources to defend the Third Party Claim and fulfill its indemnity obligations hereunder.

(c) The Indemnifying Party shall not be entitled to assume or maintain control of the defense of any Third Party Claim and shall pay the fees and expenses of one counsel retained by the Indemnified Party if (i) the Indemnifying Party does not deliver the acknowledgment referred to in Section 9.6(b)(i) within thirty (30) days of receipt of notice of the Third Party Claim pursuant to Section ‎9.3(a), (ii) the Third Party Claim relates to or arises in connection with any criminal proceeding, Action, indictment or allegation, (iii) the Indemnified Party reasonably believes an adverse determination with respect to the Third Party Claim would be detrimental to the reputation or future business prospects of the Indemnified Party or any of its Affiliates, (iv) the Third Party Claim seeks an injunction or equitable relief against the Indemnified Party or any of its Affiliates, (v) the Indemnifying Party (or the Equityholders’ Representative on behalf of the Equityholders) has failed or is failing to prosecute or defend vigorously the Third Party Claim or (vi) in the case of a Parent Indemnified Party as the Indemnified Party, if the amount of the Third Party Claim, if determined in favor of the claimant, would reasonably result in Damages, together with all other claims for indemnification hereunder, that would exceed the remaining amount of the General Escrow Amount. The Indemnified Party shall obtain the prior written consent of the Indemnifying Party before entering into any settlement of a Third Party Claim.

(d) If the Indemnifying Party shall assume the control of the defense of any Third Party Claim in accordance with the provisions of this Section 9.6, the Indemnifying Party shall obtain the prior written consent of the Indemnified Party (which shall not be unreasonably withheld, delayed or conditioned) before entering into any settlement of such Third Party Claim, if the settlement does not expressly unconditionally release the Indemnified Party and its Affiliates from all Liabilities with respect to such Third Party Claim or the settlement imposes injunctive or other equitable relief against the Indemnified Party or any of its Affiliates.

(e) In circumstances where the Indemnifying Party is controlling the defense of a Third Party Claim in accordance with paragraphs (b) and (c) above, the Indemnified Party shall be entitled to participate in the defense of any Third Party Claim and to employ separate counsel of its choice for such purpose, in which case the fees and expenses of such separate counsel shall be borne by the Indemnified Party; provided, that in such event the Indemnifying Party shall pay the fees and expenses of one such separate counsel (i) incurred by the Indemnified Party prior to the date the Indemnifying Party assumes control of the defense of the Third Party Claim or (ii) if representation of both the Indemnifying

Party and the Indemnified Party by the same counsel would, in the good faith judgment of the Indemnified Party, create a conflict of interest.

(f) Each Party shall cooperate, and cause their respective Affiliates to cooperate, in the defense or prosecution of any Third Party Claim and shall furnish or cause to be furnished such records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials or appeals, as may be reasonably requested in connection therewith.

SECTION 9.7 Direct Claim Procedures. In the event an Indemnified Party has a claim for indemnity under Section 9.2 against an Indemnifying Party that does not involve a Third Party Claim, the Indemnified Party agrees to give prompt notice in writing of such claim to the Indemnifying Party. Such notice shall set forth in reasonable detail such claim and the basis for indemnification (taking into account the information then available to the Indemnified Party). The failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent such failure shall have materially and adversely prejudiced the Indemnifying Party. If the Indemnifying Party disputes its indemnity obligation for any Damages with respect to such claim, the Parties shall proceed in good faith to negotiate a resolution of such dispute and, if not resolved through negotiations, such dispute shall be resolved by litigation in an appropriate court of jurisdiction determined pursuant to Section 10.11.

The Equityholders’ Representative shall not be liable for, and may seek indemnification from the Equityholders for, any Liability or Damage incurred by the Equityholders’ Representative while acting in good faith and in the exercise of its reasonable judgment and arising out of or in connection with the acceptance or administration of its duties under this Agreement and the Escrow Agreement, except to the extent that any such Liability or Damage is the proximate result of the gross negligence or bad faith of the Equityholders’ Representative. The Equityholders’ Representative Escrow Account shall be available to indemnify and hold the Equityholders’ Representative harmless against any Liability or Damage incurred by the Equityholders’ Representative arising out of or in connection with the acceptance or administration of its duties under this Agreement and the Escrow Agreement, except to the extent that any such Liability or Damage is the proximate result of the gross negligence or bad faith of the Equityholders’ Representative. The Equityholders’ Representative shall be entitled to recover any out-of-pocket costs and expenses reasonably incurred by the Equityholders’ Representative in connection with actions taken by the Equityholders’ Representative pursuant to the terms of Section 2.7, Article III, Article IX, Article X or the Escrow Agreement (including the hiring of legal counsel and the incurring of legal fees and costs) from the Equityholders’ Representative Escrow Account.

(c) Access. From and after the Effective Time, Parent shall cause the Surviving Corporation to provide the Equityholders’ Representative with reasonable access to information about the Surviving Corporation and the reasonable assistance of the officers and employees of Parent and the Surviving Corporation for the purposes of performing its duties and exercising its rights under this Agreement; provided, that the Equityholders’ Representative shall treat confidentially any nonpublic information about the Surviving Corporation (except in connection with the performance by the Equityholders’ Representative of its duties or the exercise of its rights under this Agreement).

(d) Actions of the Equityholders’ Representative. From and after the Effective Time, a decision, act, consent or instruction of the Equityholders’ Representative shall constitute a decision of all Equityholders and shall be final, binding and conclusive upon each Equityholder, and the Escrow Agent and Parent may rely upon any decision, act, consent or instruction of the Equityholders’

Representative as being the decision, act, consent or instruction of each Equityholder. Parent is hereby relieved from any Liability to any Person for any acts done by Parent in accordance with any such decision, act, consent or instruction of the Equityholders’ Representative.

(e) Representations and Warranties. The Equityholders’ Representative, solely in its capacity as the representative of the Equityholders, represents and warrants to Parent and Merger Sub, as of the date hereof and as of the Closing Date, as follows:

(iv) the execution and delivery of this Agreement by the Equityholders’ Representative, and the performance by the Equityholders’ Representative of its obligations hereunder and under the Escrow Agreement do not and will not (A) conflict with or result in a violation of the organizational documents of the Equityholders’ Representative, (B) violate any Law applicable to the Equityholders’ Representative or (C) require any consent or approval that has not been given or other action that has not been taken by any Person under any Contract binding upon the Equityholders’ Representative.

SECTION 10.5 Interpretation. The Article and Section headings in this Agreement are for convenience of reference only and shall not be deemed to alter or affect the meaning or interpretation of any provision of this Agreement. References to Articles, Sections, Schedules or Exhibits in this Agreement, unless otherwise indicated, are references to Articles, Sections, Schedules and Exhibits of or to this Agreement. The Parties to this Agreement have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises with respect to any term or provision of this Agreement, this Agreement shall be construed as if drafted jointly by the Parties to this Agreement, and no presumption or burden of proof shall arise favoring or disfavoring any Party to this Agreement by virtue of the authorship of any of the terms or provisions of this Agreement. Any reference to any Law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context requires otherwise. For all purposes of and under this Agreement, (i) the word “including” shall be deemed to be immediately followed by the words “without limitation;” (ii) words (including defined terms) in the singular shall be deemed to include the plural and vice versa; (iii) words of one gender shall be deemed to include the other gender as the context requires; (iv) the terms “hereof,” “herein,” “hereto,” “herewith” and any other words of similar import shall, unless otherwise stated, be construed to refer to this Agreement as a whole (including all of the Exhibits to this Agreement) and not to any particular term or provision of this Agreement, unless otherwise specified; and (v) unless otherwise defined in this Agreement, accounting terms shall have the respective meanings assigned to them in accordance with GAAP.

SECTION 10.6 Severability. In the event that any one or more of the terms or provisions contained in this Agreement or in any other certificate, instrument or other document referred to in this Agreement, shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other term or provision of this Agreement or any other such certificate, instrument or other document referred to in this Agreement. Any term or provision of this Agreement held invalid or unenforceable only in part, degree or within certain jurisdictions shall remain in full force and effect to the extent not held invalid or unenforceable to the extent consistent with the intent of the Parties as reflected by this Agreement. To the extent permitted by applicable Law, each Party waives any term or provision of Law which renders any term or provision of this Agreement to be invalid, illegal or unenforceable in any respect.

SECTION 10.7 Entire Agreement. This Agreement (including the Exhibits to this Agreement), the Company Disclosure Schedule and the Confidentiality Agreement constitute the entire agreement of the Parties to this Agreement with respect to the subject matter of this Agreement, the Company Disclosure Schedule and the Confidentiality Agreement, and supersede all prior agreements and undertakings, both written and oral, among the Parties to this Agreement with respect to the subject matter of this Agreement, the Company Disclosure Schedule and the Confidentiality Agreement, except as otherwise expressly provided in this Agreement.

SECTION 10.8 Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the Parties to this Agreement (whether by operation of Law or otherwise) without the prior written consent of the other Parties to this Agreement, and any purported assignment or other transfer without such consent shall be void and unenforceable, except that Parent or Merger Sub may transfer or assign its rights and obligations under this Agreement, in whole or from time to time in part, to (i) one or more of their Affiliates at any time and (ii) after the Effective Time, to any Person; provided, that such transfer or assignment shall not relieve Parent or Merger Sub of its obligations hereunder or enlarge, alter or change any obligation of any other party hereto or due to Parent or Merger Sub. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of and be enforceable by the Parties to this Agreement and their respective successors and assigns.

Any failure of the Parties to this Agreement to comply with any obligation, covenant, agreement or condition in this Agreement may be waived by the Party entitled to the benefits thereof only by a written instrument signed by the Party granting such waiver. No delay on the part of any Party to this Agreement in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any waiver on the part of any Party to this Agreement of any right, power or privilege hereunder operate as a waiver of any other right, power or privilege hereunder, nor shall any single or partial exercise of any right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder. Unless otherwise provided, the rights and remedies provided for in this Agreement are cumulative and are not exclusive of any rights or remedies which the Parties to this Agreement may otherwise have at Law or in equity. Whenever this Agreement requires or permits consent by or on behalf of a Party, such consent shall be given in writing in a manner consistent with the requirements for a waiver of compliance as set forth in this Section 10.10.

SECTION 10.11 Governing Law; Consent to Jurisdiction.

(a) This Agreement and the transactions contemplated hereby, and all disputes between the Parties under or related to the Agreement or the facts and circumstances leading to its execution, whether in contract, tort or otherwise, shall be governed by, and construed in accordance with, the Laws of the State of Delaware applicable to contracts executed in and to be performed entirely within such State, without regard to conflict of law principles that would result in the application of any Laws other than the Laws of the State of Delaware. Each of the Parties to this Agreement hereby irrevocably and unconditionally submits, for itself and its assets and properties, to the exclusive jurisdiction of any Delaware State court, or Federal court of the United States of America, sitting within the State of Delaware, and any appellate court from any thereof, in any Action arising out of or relating to this

Agreement, the agreements delivered in connection with this Agreement, or the transactions contemplated hereby or thereby, or for recognition or enforcement of any judgment relating thereto, and each of the Parties to this Agreement hereby irrevocably and unconditionally (i) agrees not to commence any such Action except in such courts; (ii) agrees that any claim in respect of any such Action may be heard and determined in such Delaware State court or, to the extent permitted by Law, in such Federal court; (iii) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any such Action in any such Delaware State or Federal court; and (iv) waives, to the fullest extent permitted by Law, the defense of an inconvenient forum to the maintenance of such Action in any such Delaware State or Federal court. Each of the Parties to this Agreement hereby agrees that a final judgment in any such Action shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Each of the Parties to this Agreement hereby irrevocably consents to service of process in the manner provided for notices in Section 10.3. Nothing in this Agreement shall affect the right of any Party to this Agreement to serve process in any other manner permitted by applicable Law.

(b) Buyer Parent hereby irrevocably designates, appoints, authorizes and empowers as agent for service of process, Parent, to accept, for and on behalf of Buyer Parent, service of any and all process, notices or other documents that may be served in any Action relating hereto in any Delaware State or Federal court sitting in the State of Delaware.

SECTION 10.12 Waiver of Jury Trial. EACH PARTY TO THIS AGREEMENT ACKNOWLEDGES AND AGREES THAT ANY CLAIM OR CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE, IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY TO THIS AGREEMENT CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE EITHER OF SUCH WAIVERS, (II) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (III) IT MAKES SUCH WAIVERS VOLUNTARILY AND (IV) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10.12.

SECTION 10.13 Equitable Remedies. Each of the Parties to this Agreement acknowledges and agrees that the other Parties to this Agreement would be irreparably damaged in the event that any of the terms or provisions of this Agreement are not performed in accordance with their specific terms or otherwise are breached. Therefore, notwithstanding anything to the contrary set forth in this Agreement, each of the Parties to this Agreement hereby agrees that the other Parties to this Agreement shall be entitled to an injunction or injunctions to prevent breaches of any of the terms or provisions of this Agreement, and to enforce specifically the performance by any other Party under this Agreement, and each Party to this Agreement hereby agrees to waive the defense (and not to interpose as a defense or in opposition) in any such suit that the other Parties to this Agreement have an adequate remedy at Law, and hereby agrees to waive any requirement to post any bond in connection with obtaining such relief. The equitable remedies described in this Section 10.13 shall be in addition to, and not in lieu of, any other remedies at Law or in equity that the Parties to this Agreement may elect to pursue.

SECTION 10.14 Counterparts. This Agreement may be executed in one or more counterparts, each of which when executed shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement. In the event that any signature is delivered by facsimile transmission, or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the Party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” format data file signature page were an original thereof.

SECTION 10.15 Time is of the Essence. Time is of the essence with respect to the performance of this Agreement. Whenever this Agreement refers to a number of days, such number shall refer to calendar days unless Business Days are specified. Whenever any action must be taken hereunder on or by a day that is not a Business Day, then such action may be validly taken on or by the next day that is a Business Day.

SECTION 10.16 Legal Representation. It is acknowledged by each of the parties hereto that the Company, the Equityholders’ Representative and the Principal Stockholders (and their respective Affiliates) have retained Latham & Watkins LLP (“Sellers’ Counsel”) to act as their counsel in connection with the transactions contemplated hereby and that Sellers’ Counsel has not acted as counsel for any other Person in connection with the transactions contemplated hereby and that no other party or Person has the status of a client of the Sellers’ Counsel for conflict of interest or any other purposes as a result thereof. Parent, Merger Sub and the Surviving Corporation hereby agree that, in the event that a dispute arises between Parent, Merger Sub, the Company or any of their respective Affiliates and the Equityholders’ Representative, the Principal Stockholders or any of their respective Affiliates, Sellers’ Counsel may represent the Equityholders’ Representative, the Principal Stockholders or any of their respective Affiliates in such dispute even though the interests of the Equityholders’ Representative, the Principal Stockholders or any of their respective Affiliates may be directly adverse to Parent, Merger Sub, the Company, the Surviving Corporation or any of their respective Affiliates and even though Sellers’ Counsel may have represented the Company in a matter substantially related to such dispute, and Parent, Merger Sub, the Company, the Surviving Corporation and their respective Affiliates hereby waive, on behalf of themselves and each of their Affiliates, any conflict of interest in connection with such representation by Sellers’ Counsel. Each of Parent, Merger Sub and the Company further agrees that, as to all pre-Closing communications among Sellers’ Counsel, the Company and any stockholder of the Company that relate in any way to the transactions contemplated by this Agreement, the attorney-client privilege, the expectation of client confidence and all other rights to any evidentiary privilege belong to the Equityholders’ Representative, the Principal Stockholders and their respective Affiliates, as applicable, and may be controlled by the Equityholders’ Representative, the Principal Stockholders and their respective Affiliates and shall not pass to or be claimed by Parent, Merger Sub, the Company, the Surviving Corporation or any of their respective Affiliates; provided, however, that the foregoing sentence will not be applicable with respect to disputes or claims arising under Article IX of the Merger Agreement. Parent, Merger Sub and the Company agree to take, and to cause their respective Affiliates to take, all steps necessary to implement the intent of this Section 10.16.

SECTION 10.17 Buyer Parent Guarantee. In consideration of, and as an inducement to the Company and the Equityholders’ Representative entering into this Agreement and performing their obligations hereunder, Buyer Parent hereby irrevocably, absolutely and unconditionally guarantees to the Company and the Equityholders’ Representative the full performance and payment by Parent and Merger Sub of the covenants, obligations, monetary or otherwise, and undertakings of Parent and Merger Sub pursuant to or otherwise in connection with this Agreement (the “Buyer Guaranteed Obligations”). Upon breach of, or other failure to perform, any representation, warranty, covenant, obligation, agreement or undertaking of Parent or Merger Sub, the Company or the Equityholders’

Representative shall give written notice of such breach or failure to Buyer Parent, which notice shall specify in reasonable detail the nature and basis of such breach or failure, and Buyer Parent shall have three (3) Business Days from the date such notice is given to Buyer Parent to cause Parent or Merger Sub to perform its obligations with respect to such breach or failure; provided, that if such obligations are not satisfied within such three (3) Business Day period, the Company and the Equityholders’ Representative shall have the right, exercisable in their sole discretion, to pursue any and all available remedies they may have under this Agreement arising out of any such breach or nonperformance directly against any or all of Parent, Merger Sub and Buyer Parent in the first instance. In this respect, for the avoidance of doubt, Buyer Parent confirms that it is bound by the provisions of Section 10.3, Section 10.5, Section 10.6, Section 10.7, Section 10.8, Section 10.9, Section 10.10, Section 10.11, Section 10.12, Section 10.13 and Section 10.14 as if it were a “Party” therein. This guarantee is a guarantee of performance and not exclusively of collection. Without limiting any rights or defenses that would be available to Buyer Parent if it were a direct obligor hereunder or any rights or defenses that Buyer Parent, Parent or Merger Sub has hereunder, (x) to the fullest extent permitted by Law, Buyer Parent hereby expressly waives any and all rights or defenses arising by reason of any Law that would otherwise require any election of remedies by the Company or the Equityholders’ Representative and (y) except for the second sentence of this Section 10.17, Buyer Parent waives promptness, diligence, notice of the acceptance of this guaranty and of the Buyer Guaranteed Obligations, presentment, demand for payment, notice of non-performance, default, dishonor and protest, notice of any Buyer Guaranteed Obligations incurred and all other notices of any kind, all defenses which may be available by virtue of any valuation, stay, moratorium law or other similar law now or hereafter in effect, any right to require the marshalling of assets of Buyer Parent, and all suretyship defenses generally. Buyer Parent’s obligations under this Section 10.17 shall terminate upon the satisfaction by Parent and Merger Sub of their obligations hereunder. Buyer Parent acknowledges that it will receive substantial direct and indirect benefits in connection with this Agreement and that the waivers set forth in this Section 10.17 are knowingly made in contemplation of such benefits.
