d.to the Paying Agent for the benefit of the respective Preferred Stockholders, an amount in cash equal to (i) the Estimated Merger Consideration minus (ii) the Holdback Amount (the resulting amount, the “Net Estimated Merger Consideration”).

Section 2.10. Merger Consideration Adjustments.

a.Estimated Closing Adjustment. Before the date of this Agreement, the Company has delivered to Parent a statement (the “Estimated Closing Date Statement”), so designated and reasonably acceptable to Parent, setting forth a good faith calculation, together with reasonably detailed supporting documentation, of: (i) Closing Net Working Capital and the components thereof; (ii) the amount of each of (A) Indebtedness remaining unpaid as of immediately before the Closing, (B) Change of Control Payments remaining unpaid as of immediately before the Closing (including employee-side withholding amounts to be withheld from such Change of Control Payments), (C) Company Transaction Expenses, (D) Accrued Compensation remaining unpaid as of immediately before the Closing (including employee-side withholding amounts to be withheld from such Accrued Compensation), (E) Deferred Compensation remaining unpaid as of immediately before the Closing (including employee-side withholding amounts to be withheld from such Deferred Compensation), (F) Pre-Closing Taxes (including without limitation any Pre-Closing Taxes arising as a result of the Taxable Spinout) remaining unpaid as of immediately before the Closing, and (G) (without duplication) employer-side taxes on all such unpaid Accrued Compensation and all such unpaid Deferred Compensation; and (iii) the resulting calculation of the Merger Consideration (the “Estimated Merger Consideration”). The Company represents and warrants to Parent and Merger Sub that the Estimated Closing Date Statement and the calculations thereunder were prepared and calculated by the Company in good faith.

b.Closing Date Statement. Within the 90 day period after the Closing Date (or such reasonable extension thereof as approved by the Stockholders’ Representative, such approval not to be unreasonably withheld, conditioned or delayed), Parent shall deliver, or cause to be delivered, to the Stockholders’ Representative a statement (the “Closing Date Statement”) setting forth Parent’s objections, if any, to the calculations set forth in the Estimated Closing Date Statement, together with reasonably detailed supporting documentation to substantiate any such objections, including the calculations of (i) Closing Net Working Capital; (ii) the amount of each of (A) Indebtedness remaining unpaid as of immediately before the Closing, (B) Change of Control Payments remaining unpaid as of immediately before the Closing (including employee-side withholding amounts to be withheld from such Change of Control Payments), (C) Company

Transaction Expenses, (D) Accrued Compensation remaining unpaid as of immediately before the Closing (including employee-side withholding amounts to be withheld from such Accrued Compensation), (E) Deferred Compensation remaining unpaid as of immediately before the Closing (including employee-side withholding amounts to be withheld from such Deferred Compensation), (F) Pre-Closing Taxes (including without limitation any Pre-Closing Taxes arising as a result of the Taxable Spinout) remaining unpaid as of immediately before the Closing, and (G) (without duplication) employer-side taxes on all such unpaid Accrued Compensation and all such unpaid Deferred Compensation; and (iii) the resulting calculation of the Merger Consideration. The Closing Date Statement and the calculations thereunder shall be prepared and calculated by Parent in good faith.

c.Disputes.

i.If the Stockholders’ Representative disputes any of Parent’s objections to the Estimated Closing Date Statement as set forth in the Closing Date Statement, then, within 15 days after the delivery to the Stockholders’ Representative of the Closing Date Statement (the “Dispute Period”), the Stockholders’ Representative shall deliver to Parent a written notice (a “Dispute Notice”) describing in reasonable detail the Stockholders’ Representative’s dispute of any of Parent’s objections to the Estimated Closing Date Statement set forth in such Closing Date Statement. If the Stockholders’ Representative does not deliver a Dispute Notice to Parent during the Dispute Period, then Parent’s objections set forth in the Closing Date Statement shall be binding and conclusive on the parties hereto and on the Stockholders. Notwithstanding anything to the contrary set forth herein, the Stockholders’ Representative shall have the right to deliver a Dispute Notice based on fraud, willful misconduct or intentional misrepresentation discovered by the Stockholders’ Representative at any time (as determined by a non-appealable and binding decision by a court of law having jurisdiction over the parties).

ii.If the Stockholders’ Representative delivers a Dispute Notice, and if the Stockholders’ Representative and Parent are unable to resolve the objections set forth in the Closing Date Statement within 10 Business Days after such Dispute Notice is delivered to Parent, the dispute shall be finally settled by the Accounting Firm. Within 10 days after the Accounting Firm is appointed, Parent shall forward a copy of the Closing Date Statement to the Accounting Firm, and the Stockholders’ Representative shall forward a copy of the Dispute Notice to the Accounting Firm, together with, in each case, all relevant supporting documentation. The Accounting Firm’s role shall be limited to resolving such objections and determining the correct calculations to be used on only the disputed portions of the Closing Date Statement, and the Accounting Firm shall not make any other determination, including any determination as to whether any other items on the Closing Date Statement are correct or whether the Target Net Working Capital is correct. The Accounting Firm shall not assign a value to any item greater than the greatest value for such item claimed by the Stockholders’ Representative or Parent or less than the smallest value for such item claimed by the Stockholders’ Representative or Parent and shall be limited to the selection of either the Stockholders’ Representative’s or Parent’s position on a disputed item (or a position in between the positions of the Stockholders’ Representative or Parent) based solely on presentations and supporting material provided by the parties and not pursuant to any independent review. In resolving such objections, the Accounting Firm shall apply the provisions of this Agreement concerning determination of the amounts set forth in the Closing Date Statement. The Stockholders’ Representative and Parent shall instruct the Accounting Firm to deliver to the Stockholders’ Representative and Parent a written determination (such determination to include a work sheet setting forth all material calculations used in arriving at such determination and to be based solely on information provided to the Accounting Firm by the Stockholders’ Representative and Parent) of the disputed items submitted to the Accounting Firm within 30 calendar days of receipt of such disputed items. The determination by the Accounting Firm of the disputed amounts and the Merger Consideration shall be conclusive and binding on the parties hereto, absent manifest error or fraud or willful misconduct as

determined by a non-appealable and binding decision by a court of law having jurisdiction over the parties. The fees and expenses of the Accounting Firm incurred pursuant to this Section 2.10(c)(ii) shall be allocated between Parent, on the one hand, and the Stockholders’ Representative (on behalf of the Stockholders), on the other hand, based upon the percentage that the amount actually contested but not awarded to the Stockholders’ Representative (on behalf of the Stockholders) or Parent, respectively, bears to the aggregate amount actually contested by the Stockholders’ Representative and Parent. All other fees and expenses incurred in connection with the dispute resolution process set forth in this Section 2.10(c)(ii), including fees and expenses of attorneys and accountants, shall be borne and paid by the party incurring such expenses. The parties agree that (except as otherwise provided in Section 7.2(a)(iii) and Section 7.2(a)(vi)) the procedure set forth in this Section 2.10 for resolving disputes with respect to Closing Net Working Capital, Indebtedness, Change of Control Payments, Company Transaction Expenses, Accrued Compensation, Deferred Compensation, Pre-Closing Taxes, and employer-side taxes on unpaid Accrued Compensation and unpaid Deferred Compensation, and the resulting calculation of the Merger Consideration shall be the sole and exclusive remedy for resolving such disputes; provided, however, that the parties agree that judgment may be entered upon the determination of the Accounting Firm in any court having jurisdiction over the party against which such determination is to be enforced.

d.Payment of Merger Consideration Adjustment.

i.If the Merger Consideration, as finally determined in accordance with this Section 2.10 (the “Final Merger Consideration”), exceeds the Estimated Merger Consideration (such excess, a “Merger Consideration Surplus”), such Merger Consideration Surplus shall be distributed to the Stockholders in accordance with Section 2.15 below.

ii.If the Estimated Merger Consideration exceeds the Final Merger Consideration (such excess, a “Merger Consideration Deficit”), the Holdback Amount payable to Stockholders shall be reduced by the amount of the Merger Consideration Deficit. If the Merger Consideration Deficit exceeds the Holdback Amount, the excess shall reduce (from the first dollars otherwise payable) the Additional Merger Consideration (if any).

Section 2.11. Paying Agent; Payment Procedures.

(a) Paying Agent. At or before the Closing, Parent shall designate a bank or trust company or other Person reasonably acceptable to the Company to act as paying agent in the Merger (the “Paying Agent”), pursuant to an agreement that requires the Paying Agent to comply with the procedures set forth in this Section 2.11; or, if Parent does not so designate, then Parent itself shall serve as the Paying Agent, mutatis mutandis. It is understood that as of the Closing the Paying Agent shall be Acquiom Financial LLC. At the Effective Time, Parent shall deposit with the Paying Agent, for payment through the Paying Agent in accordance with this Section 2.11, funds in an amount equal to the Net Estimated Merger Consideration (the “Payment Fund”). The Paying Agent shall cause the Payment Fund and any other funds that may be deposited with the Paying Agent pursuant to the terms of this Agreement to be: (i) held for the benefit of the Stockholders as of immediately before the Effective Time; and (ii) applied promptly to making the payments to such Stockholders as required by the terms hereof. The Payment Fund and any such other funds shall not be used for any other purpose, except as provided in this Agreement.

(b) Payment Procedures.

(i) Promptly following the Closing, the Surviving Corporation shall, or shall cause the Paying Agent to, deliver to each Stockholder a customary letter of transmittal (the “Letter of Transmittal”), which shall, among other things: (A) contain instructions for surrendering such Stockholder’s Certificates (if applicable),

delivering the Letter of Transmittal and receiving (if applicable) such Stockholder’s Pre-Preference-Satisfaction Pro Rata Share of the Net Estimated Merger Consideration and (if and when ever applicable) until the point of Preference Satisfaction, such holder’s Pre-Preference-Satisfaction Pro Rata Share of the Additional Merger Consideration (if any) and (if and when ever applicable) after the point of Preference Satisfaction, such holder’s Post-Preference-Satisfaction Pro Rata Share of the Additional Merger Consideration (if any); (B) contain warranties of such Stockholder as to title to such Stockholder’s shares of Company Capital Stock and the authority to execute and deliver the relevant documents; and (C) specify that delivery shall be effected, and risk of loss and title to such shares of Company Capital Stock shall pass, upon proper delivery to the Paying Agent of such Stockholder’s Certificates (if applicable) and a properly completed Letter of Transmittal; and (D) contain an acknowledgement of such Stockholder’s indemnification obligations under this Agreement and an agreement to be bound by the provisions of this Agreement applicable to the Stockholders.

(ii) With respect to any duly completed and validly executed Letter of Transmittal delivered to the Paying Agent after the Closing, together with surrender of the Stockholder’s Certificates (if applicable), the Paying Agent shall, as promptly as practicable, pay to such Stockholder such Stockholder’s Pre-Preference-Satisfaction Pro Rata Share of the Net Estimated Merger Consideration, without interest and net of any Taxes required to be withheld therefrom, by wire transfer of immediately available funds to an account or accounts specified in the Letter of Transmittal (or, if so expressly requested by the Stockholder in writing to the Paying Agent, by check).

(iii) If payment is to be made to a Person other than the Person in whose name the shares of Company Capital Stock represented by a Certificate or equivalent book-entry are registered, it shall be a condition of payment that: (A) the Certificate surrendered shall be properly endorsed or shall otherwise be in proper form for transfer; (B) the Letter of Transmittal delivered to the Paying Agent shall be properly executed and otherwise in proper form; and (C) the Person requesting such payment shall pay any Taxes required by reason of the payment to a Person other than the Person in whose name the shares of Company Capital Stock are registered, or establish to the satisfaction of the Paying Agent that such Tax has been paid or is not applicable.

(iv) After the Effective Time, there shall be no transfers of shares of Company Capital Stock on the transfer books of the Surviving Corporation. If, after the Effective Time, a request for the transfer of shares of Company Capital Stock or any Certificate or equivalent book-entry is presented to Parent, the Paying Agent or the Surviving Corporation, the relevant shares of Company Capital Stock shall be canceled and exchanged for the consideration as provided in Section 2.6 and this Section 2.11.

(v) In the event that any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed (which affidavit shall contain a binding undertaking to indemnify Parent, the Paying Agent and the Surviving Corporation against any claim that may be made against Parent, the Paying Agent or the Surviving Corporation on account of the loss, theft or destruction of such Certificate), the Paying Agent shall pay in respect of such lost, stolen or destroyed Certificate the consideration payable in respect of the shares of Company Capital Stock formerly represented by such Certificate in accordance with Section 2.6(c)/Section 2.6(d).

(vi) Any portion of the Payment Fund that remains undistributed to the Stockholders 12 months after the Closing Date will be promptly delivered to Parent by the Paying Agent along with any and all earnings thereon, and any Stockholder shall look only to Parent or the Surviving Corporation for satisfaction of any claims for their right to receive the Merger Consideration. Any portion of the Payment Fund that remains undistributed immediately before the time at which such amounts would otherwise escheat or become property of any Governmental Entity shall, to the extent permitted by applicable Law, become the property of Parent, free and clear of all claims or interest of any Person previously entitled thereto. None of the Paying Agent, Parent or the Surviving Corporation will

be liable to any Stockholder for any part of the Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

Section 2.12. Required Withholdings. Notwithstanding anything to the contrary set forth in this Agreement, Parent, the Surviving Corporation and the Paying Agent will be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of Company Capital Stock such amounts as are required under the Code or any provision of state, local or foreign Tax Law. To the extent that amounts are so withheld by Parent, the Surviving Corporation or the Paying Agent, and timely paid over to the appropriate Governmental Entity, such withheld amounts will be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Capital Stock in respect of which such deduction and withholding were made by Parent, the Surviving Corporation or the Paying Agent. Notwithstanding the foregoing, no federal income Tax back-up withholding amount shall be withheld from any payment made hereunder to a holder of shares of Company Capital Stock who provides Parent, the Surviving Corporation or the Paying Agent with a properly completed Internal Revenue Service Form W-9 or substitute Form W-9, or who otherwise provides Parent, the Surviving Corporation or the Paying Agent with appropriate evidence that such Person is exempt from federal income Tax back-up withholding.

Section 2.13. Dissenting Shares. Notwithstanding anything to the contrary set forth in this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, each outstanding Dissenting Share shall not be converted into or represent the right to receive the consideration payable in respect of such shares in accordance with Section 2.6(c)/Section 2.6(d), but the holder thereof shall be entitled only to such rights as are granted by the applicable provisions of the DGCL; provided, however, that all Dissenting Shares held by an individual or entity who shall have failed to perfect or who shall, after the Effective Time, withdraw the demand for appraisal or lose the right of appraisal, in either case pursuant to Section 262 of the DGCL, shall thereupon be deemed to have been converted into, and to have become exchangeable for, as of the Effective Time, the right to receive the consideration payable in respect of such shares in accordance with Section 2.6(c)/Section 2.6(d), without interest and net of any Taxes required to be withheld therefrom, upon surrender in the manner provided in Section 2.11. Within 10 days after the Effective Time, the Surviving Corporation shall notify each Stockholder who is entitled to appraisal rights that the Merger has become effective and that appraisal rights are available pursuant to Section 262 of the DGCL.

Section 2.14. Closing Deliveries. At the Closing:

(a) The Stockholders’ Representative shall deliver, or cause to be delivered, to Parent or any other Person designated by Parent (unless the delivery is waived in writing by Parent), the following documents, in each case duly executed or otherwise in proper form:

A certificate, in a form satisfactory to Parent, signed by the Secretary of the Company and dated as of the Closing Date, certifying: (A) the Certificate of Incorporation; (B) the Bylaws; and (C) resolutions of the Company Board (I) determining that it is in the best interests of the Company and the Stockholders, and declaring it advisable, to enter into this Agreement, (II) approving the execution, delivery and performance by the Company of this Agreement and the consummation of the Transactions, including the Merger, and (III) recommending adoption of this Agreement and approval of the Transactions, including the Merger, by the Stockholders;

c.Each Benefit Plan is being operated, funded and administered in all material respects in accordance with its terms and the requirements of ERISA and the Code and other applicable Law.  Each Benefit Plan that is intended to be qualified within the meaning of Section 401(a) of the Code and each trust associated with any Benefit Plan that is intended to be exempt from taxation under Section 501(a) of the Code has received a favorable Internal Revenue Service determination letter as to its qualification and to the effect that each such trust is exempt from taxation under Section 501(a) of the Code, or is a prototype plan that is the subject of a favorable opinion letter from the Internal Revenue Service and, to the Company’s Knowledge, as of the date of this Agreement, nothing has occurred since the date of such determination or opinion letter that

would reasonably be expected to result in a loss of such plan’s qualification or tax-exempt status. No “prohibited transaction” within the meaning of Section 406 of ERISA has occurred with respect to any Benefit Plan, and no Tax has been imposed pursuant to Section 4975 of the Code in respect thereof.

d.Neither the Company nor any ERISA Affiliate maintains, contributes to or has any Liability with respect to a “single-employer plan” within the meaning of Section 4001(a)(15) of ERISA or a “multiemployer plan” within the meaning of Section 4001(a)of ERISA.

e.There are no actions, suits or claims (other than routine claims for benefits in the ordinary course) pending or, to the Company’s Knowledge, threatened with respect to any Benefit Plan.

f.Neither the execution and delivery of this Agreement by the Company nor the consummation by the Company of the Transactions (either alone or in conjunction with any other event) will:  (i) increase any benefits otherwise payable under any Benefit Plan; (ii) result in any acceleration of the time of payment or vesting of any such benefits (other than the accelerated vesting of outstanding-but-to-be-terminated Company Options under the Company Option Plan); or (iii) result in any payment (whether severance pay or otherwise) becoming due to, or with respect to, any current or former employee or director of the Company.

g.No Benefit Plan is a “welfare benefit plan” within the meaning of Section 3(1) of ERISA that provides benefits to former employees of the Company, other than pursuant to Section 4980B of the Code or any similar Law.

h.To the Knowledge of the Company, the Company has no Liability by reason of an individual who performs or performed services for the Company in any capacity being improperly excluded from participating in a Benefit Plan.

i.Each Benefit Plan which is a “non-qualified deferred compensation plan” (as such term is defined in Section 409A(d)(1) of the Code) (i) has, at all times, been administered in compliance with the requirements of Section 409A of the Code and applicable guidance issued thereunder, and (ii) is in a form which complies with the requirements of Section 409A of the Code, so that its terms and provisions comply with the requirements of Section 409A of the Code; in all cases so that the additional tax described in Section 409A(a)(1)(B) of the Code will not be assessed against the individuals participating in any such non-qualified deferred compensation plan with respect to benefits due or accruing thereunder.

j.The Company has no indemnity obligations for any Taxes imposed under Section 409A of the Code.

Section 3.16. Intellectual Property.

a.Registered Intellectual Property. A schedule delivered by the Company to Parent before the date hereof, and so designated, accurately identifies: (i) each item of Registered Intellectual Property in which the Company has or purports to have an ownership interest of any nature (whether exclusively, jointly with another Person or otherwise); (ii) the jurisdiction in which such item of Registered Intellectual Property has been registered or filed and the applicable registration or serial number; (iii) for each item of Registered Intellectual Property that is a domain name, information about the Domain Name Registrar with which such domain name has been registered or filed; (iv) each action, filing, and payment that (to the Company’s Knowledge) must be taken or made on or before the date that is 120 days after the date of this Agreement in order to maintain such item of Registered Intellectual Property in full force and effect; and (v) any other Person that has an ownership interest in such item of Registered Intellectual Property and the nature of such ownership interest. The Company has delivered to Parent complete and accurate copies of all applications, material correspondence with any Governmental Entity and other material documents related to each such item of Registered Intellectual Property.

b.Inbound Licenses. A schedule delivered by the Company to Parent before the date hereof, and so designated, accurately identifies each Contract to which the Company is a party and pursuant to which any material Intellectual Property is or has been licensed to the Company, excluding material transfer agreements and non-exclusive licenses concerning rights that are not material to the business of the Company (each, an “Inbound IP Contract”).

Each current or former employee, consultant or independent contractor of the Company who is or was involved in the creation or development of any Owned Intellectual Property has signed a valid and enforceable agreement containing an irrevocable assignment of any rights such employee, consultant or independent contractor may have had in any Owned Intellectual Property to the Company (or, in the case of any consultant or independent contractor who provided services to the Company through an entity, to such entity who in turn assigned all such rights to the Company) and containing confidentiality provisions protecting the Company’s confidential information. The Company has taken reasonable steps to maintain the confidentiality of and otherwise protect and enforce its rights in all material proprietary information pertaining to the Company and all of the Company’s trade secrets.

iv.Except for documents cited by a patent examiner or by the patent applicant in an information disclosure statement (and which have been separately and specially disclosed by the Company to Parent), with respect to any patent applications or patents included in the Owned Intellectual Property or Licensed Intellectual Property, to the Company’s Knowledge there are no facts that the Company believes are reasonably likely to (A) preclude the issuance to the Company of any patents from patent applications included in the Owned Intellectual Property or Licensed Intellectual Property (with valid claims not materially narrower in scope than the claims as currently pending in those applications), (B) render any patents included in the Owned Intellectual Property or Licensed Intellectual Property invalid or unenforceable, or (C) cause the claims of any patent applications or patents included in the Owned Intellectual Property or Licensed Intellectual Property to be narrowed.

v.No Person has in writing asserted or threatened a claim which if adversely resolved would adversely affect the Company’s ownership rights to or license rights under (nor are there any facts known to the Company that the Company believes are reasonably likely to adversely affect the Company’s ownership rights to or license rights under) any of the Owned Intellectual Property or Licensed Intellectual Property.

vi.For the purposes of this Section 3.16(h), “Licensed Intellectual Property” shall be deemed not to include in-licenses of standard commercially-available software.

To the Knowledge of the Company, no Person has infringed, misappropriated or otherwise violated, and no Person is currently infringing, misappropriating or otherwise violating, any Owned Intellectual Property or exclusively Licensed Intellectual Property. To the Company’s Knowledge, neither the Company nor any Representative of the Company has ever sent any letter or other written or electronic communication or correspondence regarding any actual, alleged or suspected infringement or misappropriation of any Owned Intellectual Property or exclusively Licensed Intellectual Property.

k.No Infringement of Third Party IP Rights. The conduct of the business of the Company has never infringed (directly, contributorily, by inducement or otherwise), misappropriated or otherwise violated or made unlawful use of any valid and enforceable Intellectual Property of any Person, and the future conduct of the business of the Company, as currently contemplated by the Company as of the date of this Agreement, would not infringe (directly, contributorily, by inducement or otherwise), misappropriate or otherwise violate or make unlawful use of any valid and enforceable Intellectual Property of any Person. No Intellectual Property infringement, misappropriation or similar Proceeding is pending against the Company or to the Company’s Knowledge, against any other Person who is entitled to be indemnified, defended, held harmless or reimbursed by the Company with respect to such Proceeding. Except as specified on a schedule delivered by the Company to Parent before the date hereof, and so designated, the Company has never received

any notice in writing or other communication (in writing) relating to any actual, alleged or suspected past or possible future infringement, misappropriation or violation by the Company, or by any current or former employee or agent of the Company, or by any hypothetical acquirer of the Company, of any Intellectual Property of any Person, including any letter or other communication suggesting or offering that the Company obtain a license to any Intellectual Property. If (but for this sentence) anything would be deemed to be a violation of both of this Section 3.16(k) and of another representation/warranty in another section or subsection of this Article III, it shall be treated as a violation of this Section 3.16(k) and not of such other representation/warranty in such other section or subsection of this Article III.

l.Sponsored Research. No university, Governmental Entity or other organization sponsored research and development conducted by the Company in such a way as to have any claim of right to or ownership of or other Lien on any Owned Intellectual Property.

The Company IT Systems that are currently used by the Company constitute all the information and communications technology reasonably necessary to carry on the business of the Company as currently conducted. The consummation of the Transactions will not impair or interrupt in any material respect: (i) the Company’s access to and use of, or its right to access and use, the Company IT Systems or any third party databases or third party data used in connection with the business of the Company as currently conducted; and (ii) to the extent applicable, the Company’s customers’ access to and use of the Company IT Systems.

respect to jurisdictions that recognize such concept) in each jurisdiction in which the nature of the business conducted by it or the character or location of the properties and assets owned, operated or leased by it makes such licensing or qualification necessary, except where the failure to be so licensed or qualified or in good standing would not reasonably be expected to have, when aggregated with all other such failures, a material adverse effect on Parent’s or Merger Sub’s ability to perform its obligations under this Agreement or prevent the consummation of the Transactions (a “Parent Material Adverse Effect”).

Section 4.2. Authority. Each of Parent and Merger Sub has all necessary power and authority to execute and deliver this Agreement, to perform its obligations hereunder and to consummate the Transactions to be consummated by it. The execution and delivery by Parent and Merger Sub of this Agreement, the performance by each of Parent and Merger Sub of its obligations hereunder, and the consummation by each of Parent and Merger Sub of the Transactions to be consummated by it, have been duly and validly authorized by all necessary action on the part of Parent and Merger Sub, and no other or further action or proceeding on the part of Parent or Merger Sub or their respective equity holders is necessary to authorize the execution and delivery by Parent and Merger Sub of this Agreement, the performance by each of Parent and Merger Sub of its obligations hereunder and the consummation by each of Parent and Merger Sub of the Transactions to be consummated by it.  This Agreement has been duly executed and delivered by Parent and Merger Sub and, assuming the due and valid authorization, execution and delivery of this Agreement by the Company, constitutes a valid and binding obligation of each of Parent and Merger Sub, enforceable against each of them in accordance with its terms, except that such enforceability: (a) may be limited by bankruptcy, insolvency, moratorium or other similar Laws affecting or relating to the enforcement of creditors’ rights generally; and (b) is subject to general principles of equity.

a.Except for the filing of the Certificate of Merger with the Delaware Secretary of State, no Consent of, or filing, declaration or registration with, or notice to any Governmental Entity, which has not been received or made, is required to be obtained by or made by Parent or Merger Sub for the execution and delivery by each of Parent and Merger Sub of this Agreement or for the consummation by each of Parent and Merger Sub of the Transactions to be consummated by it, other than such Consents, filings, declarations, registrations or notices that, if not obtained or made, would not reasonably be expected to have, individually or in the aggregate, a Parent Material Adverse Effect.

b.The execution and delivery by each of Parent and Merger Sub of this Agreement, the performance by each of Parent and Merger Sub of its obligations hereunder, and the consummation by each of Parent and Merger Sub of the Transactions to be consummated by it do not and will not: (i) conflict with or violate any provision of the organizational or governing documents of Parent or Merger Sub; (ii) conflict with or result in a violation or breach of any Law applicable to Parent or Merger Sub or any of their respective properties or assets; (iii) conflict with, result in a violation or breach of, result in the loss of any material benefit under, constitute a default (or an event which, with notice or lapse of time, or both, would constitute a default) under, result in the termination, modification or cancellation of or a right of termination, modification or cancellation under, or accelerate the performance required under, any Contract to which Parent or Merger Sub is a party, or by which either of them or any of their respective properties or assets may be bound or affected; or (iv) result in the creation of any Lien upon any of the respective properties or assets of Parent or Merger Sub, except for such conflicts, violations, breaches, losses of benefits, defaults, events, terminations, rights of termination or cancellation, accelerations or Lien creations as would not reasonably be expected to have, individually or in the aggregate, a Parent Material Adverse Effect.

Section 4.4. Broker’s Fees. None of Parent, or any of its Affiliates, or any of its officers or directors on behalf of Parent or any of its Affiliates, has employed any financial advisor, broker or finder in a manner that would

result in any Liability for the Company for any broker’s fees, commissions or finder’s fees in connection with any of the Transactions.

Parent and its Affiliates (including, for the avoidance of doubt, the Surviving Corporation after the Effective Time) shall be permitted to issue, in their sole discretion, one or more press releases or other public or industry announcements, statements or acknowledgments with respect to this Agreement or any of the Transactions, including the Merger.

Section 5.2. Further Assurances. Subject to the terms and conditions of this Agreement, each of the parties hereto agrees that, from and after the date hereof, at the reasonable request of the other party or parties, they shall execute and deliver, or cause to be executed and delivered, to the other party or parties such further documents or instruments of any kind and take, or cause to be taken, such other actions as may be reasonably necessary, proper or advisable to carry out any of the provisions of this Agreement or the Transactions.

b.From and after the Closing, no Stockholder shall, and each Stockholder shall cause his, her or its Affiliates not to, and shall instruct his, her or its and their respective Representatives not to, use any Company Confidential Information except with respect to information referenced in clauses (i) through (iii) of Section 5.3(a) or as expressly authorized in writing by Parent or the Surviving Corporation. Each Stockholder shall, and shall cause his, her or its Affiliates to, and shall instruct his, her or its and their respective Representatives to, take the same degree of care to protect the Company Confidential Information that such Person uses to protect his, her or its own trade secrets and confidential information of a similar nature, which shall be no less than a reasonable degree of care.

independent of the others and severally enforceable, and each of which is in addition to, and not in lieu of, any other rights and remedies available to Parent or the Surviving Corporation under law or in equity:

i.the right and remedy to have such provision specifically enforced by any court having jurisdiction, it being acknowledged and agreed that any such breach or threatened breach may cause irreparable injury to each of Parent and the Surviving Corporation and that money damages may not provide an adequate remedy to Parent and the Surviving Corporation; and

ii.the right and remedy to recover from the applicable Preferred Stockholder all monetary damages suffered by Parent or the Surviving Corporation, as the case may be, as the result of any acts or omissions constituting a breach of this Section 5.4.

c.Each Preferred Stockholder acknowledges that the restrictions contained in this Section 5.4 (i) are reasonable and necessary to protect the legitimate interests of Parent and the goodwill, customer relationships, and Intellectual Property purchased by Parent and (ii) constitute a material inducement to Parent to enter into this Agreement and consummate the Transactions.

Section 5.5. General Release.

a.Each Stockholder, on behalf of himself, herself or itself and each of his, her or its past, present and future Affiliates, firms, corporations, limited liability companies, partnerships, trusts, associations, organizations, Representatives, investors, stockholders, members, partners, trustees, principals, consultants, contractors, family members, heirs, executors, administrators, predecessors, successors and assigns (each, a “Releasing Party” and, collectively, the “Releasing Parties”), hereby absolutely, unconditionally and irrevocably releases, acquits and forever discharges the Company, its former, present and future Affiliates, parent and subsidiary companies, joint ventures, predecessors, successors and assigns (including Parent, the Surviving Corporation and their respective Affiliates), and their respective former, present and future Representatives, investors, stockholders, members, partners, insurers and indemnitees (collectively the “Released Parties”), of and from any and all manner of action or inaction, cause or causes of action, Proceedings, Liens, Contracts, promises, Liabilities or Damages (whether for compensatory, special, incidental or punitive Damages, equitable relief or otherwise) of any kind or nature whatsoever, past, present or future, at law, in equity or otherwise (including with respect to conduct which is negligent, grossly negligent, willful, intentional, with or without malice, or a breach of any duty, Law or rule), whether known or unknown, whether fixed or contingent, whether concealed or hidden, whether disclosed or undisclosed, whether liquidated or unliquidated, whether foreseeable or unforeseeable, whether anticipated or unanticipated, whether suspected or unsuspected, which such Releasing Parties, or any of them, ever have had or ever in the future may have against the Released Parties, or any of them, and which are based on acts, events or omissions occurring up to and including the Effective Time (the “Released Claims”); provided, however, that the foregoing release shall not release, impair or diminish, and the term “Released Claims” shall not include, in any respect any rights of: (i) the Stockholders under this Agreement; or (ii) the Releasing Parties to indemnification, reimbursement or advancement of expenses under the provisions of the Certificate of Incorporation or Bylaws (or any directors’ and officers’ liability insurance policy maintained by the Company in respect of the same) if any Releasing Party is made a party to a Proceeding as a result of such Releasing Party’s status as an officer, director or employee of the Company with respect to any act, omission, event or transaction occurring on or before the Effective Time.

b.Without limiting the generality of Section 5.5(a), with respect to the Released Claims, each Stockholder, on behalf of himself, herself or itself and each Releasing Party, hereby expressly waives all rights under Section 1542 of the California Civil Code and any similar Law or common law principle in any

applicable jurisdiction prohibiting or restricting the waiver of unknown claims. Section 1542 of the California Civil Code reads as follows:

“A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS THAT THE CREDITOR OR RELEASING PARTY DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, AND THAT IF KNOWN BY HIM OR HER, WOULD HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR OR RELEASED PARTY.”

Notwithstanding the provisions of Section 1542 of the California Civil Code or any similar Law or common law principle in any applicable jurisdiction, and for the purpose of implementing a full and complete release and discharge of the Released Parties, each Stockholder, on behalf of himself, herself or itself and each Releasing Party, expressly acknowledges that the foregoing release is intended to include in its effect all claims which any Stockholder or any Releasing Party does not know or suspect to exist in his, her or its favor against any of the Released Parties (including unknown and contingent claims), and that the foregoing release expressly contemplates the extinguishment of all such claims (except to the extent expressly set forth herein).

c. Each Stockholder, on behalf of himself, herself or itself and each Releasing Party, acknowledges that he, she or it may hereafter discover facts in addition to or different from those which he, she or it now knows or believes to be true with respect to the subject matter of the Released Claims, but each Stockholder, on behalf of himself, herself or itself and each Releasing Party, intends to and, by operation of this Agreement shall have, fully, finally and forever settled and released any and all Released Claims without regard to the subsequent discovery of existence of such different or additional facts.

d. Each Stockholder, on behalf of himself, herself or itself and each Releasing Party, represents, warrants, covenants and agrees that such Releasing Party has not assigned or transferred and will not assign or transfer any Released Claim or possible Released Claim against any Released Party. Each Stockholder, on behalf of himself, herself or itself and each Releasing Party, agrees to indemnify and hold the Released Parties harmless from any Liabilities, Damages, costs, expenses and attorneys’ fees arising as a result of any such assignment or transfer.

e. Each Stockholder, on behalf of himself, herself or itself and each Releasing Party, covenants and agrees not to, and agrees to cause his, her or its respective Affiliates not to, whether in his, her or its own capacity, as successor, by reason of assignment or otherwise, assert, commence, institute or join in, or assist or encourage any third party in asserting, commencing, instituting or joining in, any Proceeding of any kind whatsoever, in law or equity, in each case against the Released Parties, or any of them, with respect to any Released Claims.

Section 5.6. Director and Officer Insurance; Indemnification.

a.Prior to the Effective Time, the Company shall, at its own expense, purchase an extended reporting period endorsement under the Company’s existing directors’ and officers’ liability insurance coverage in a form reasonably acceptable to Parent that shall provide the current and former members of the Company Board and the Company’s officers (collectively, the “Indemnified D&Os”) with coverage for six (6) years following the Effective Time of not less than the existing coverage and have other terms not materially less favorable to the insured persons than the Company’s directors’ and officers’ liability insurance coverage presently maintained by the Company.

b.The Surviving Corporation will not knowingly take any action to alter or impair any indemnification provisions now existing in the Certificate of Incorporation or Bylaws for the benefit of any Indemnified D&Os; provided, however, that no individual who served as a director or officer of the

Company at any time prior to the Effective Time shall be entitled to indemnification from the Surviving Corporation for any matter which any Indemnitee (as hereinafter defined) is entitled to indemnification pursuant to Article VII.

Section 5.7. Section 280G.  The Company shall submit to all the Stockholders for approval (in a manner reasonably satisfactory to Parent), by the holders of such number of shares of Company Capital Stock as is required by the terms of Section 280G(b)(5)(B) of the Code, any payments and/or benefits that may separately or in the aggregate, constitute “parachute payments” pursuant to Section 280G of the Code (“Section 280G Payments”) (which determination shall be made by the Company and shall be subject to the reasonable review and approval by Parent), such that such payments and benefits shall not be deemed to be Section 280G Payments, and prior to the Effective Time the Company shall deliver to Parent evidence reasonably satisfactory to Parent that (A) a vote of the Stockholders was solicited in conformance with Section 280G and the regulations promulgated thereunder (including the distribution of an appropriate information statement and execution of a 280G Waiver in advance of such distribution) and the requisite Stockholder approval was obtained with respect to any payments and/or benefits that were subject to the Stockholder vote (the “Section 280G Stockholder Approval”), or (B) that the Section 280G Stockholder Approval was not obtained and as a consequence, that such payments and/or benefits shall not be made or provided to the extent they would cause any amounts to constitute Section 280G Payments, pursuant to the waivers of those payments and/or benefits (the “280G Waiver”), which were executed by the affected individuals prior to the Stockholder vote.

Section 6.1. Conflict. In the event of any conflict or overlap between the provisions of this Article VI and Article VII, the provisions of this Article VI shall control.

Section 6.2. Tax Returns. Parent shall, or shall cause the Surviving Corporation to, prepare or cause to be prepared (consistent with past practice, except as required by applicable Law) and file or cause to be filed all Tax Returns of the Company for all periods ending on or before the Closing Date that are required to be filed after the Closing Date. Parent shall provide the Stockholders’ Representative with a copy of each such income or other material Tax Return reflecting an amount for which indemnity will be sought under Article VII at least 20 days before the applicable filing date and shall consider in good faith the Stockholders’ Representative’s comments to such Tax Return.

Section 6.3. Cooperation on Tax Matters. Parent, the Surviving Corporation, the Stockholders and the Stockholders’ Representative shall fully cooperate, to the extent reasonably requested by the other party, with respect to the filing of Tax Returns, filing of Tax elections, and any audit, litigation or other Proceeding with respect to Taxes. Such cooperation shall include the retention and provision of records and information relevant to such audit, litigation or other Proceeding and making employees available on a mutually convenient basis to provide additional information. Parent, the Stockholders and the Stockholders’ Representative agree to retain records with respect to Tax matters pertinent to the Company until the expiration of the relevant statute of limitations. Parent, the Stockholders and the Stockholders’ Representative further agree to use their reasonable efforts to obtain any certificate or other document from any Governmental Entity as may be necessary to mitigate, reduce or eliminate any Tax that may be imposed.

Section 6.4. Tax Contests. The Stockholders’ Representative shall promptly notify Parent upon receipt by any Stockholder or the Stockholders’ Representative of any written notice of any inquiries, claims, assessments, audits or similar events with respect to Taxes relating to a Pre-Closing Tax Period (any such inquiry, claim, assessment, audit or similar event, a “Tax Matter”). Subject to Section 6.8, in Parent’s sole discretion, Parent may elect to have sole control of the conduct of any Tax Matter, including any settlement or compromise thereof; provided that Parent shall

not settle or compromise such Tax Matter without the prior written consent of the Stockholders’ Representative (not to be unreasonably withheld, conditioned or delayed; and provided that if such consent is unreasonably withheld, conditioned or delayed such consent shall not be considered to be required ). If Parent does not elect to have such sole control, the Stockholders’ Representative shall, and shall cause the Stockholders to, provide copies of all correspondence with the applicable Governmental Entity, and neither the Stockholders nor the Stockholders’ Representative shall settle or compromise such Tax Matter without the prior written consent of Parent (not to be unreasonably withheld, conditioned or delayed). Except as otherwise provided in this Section 6.4 or Section 6.8, Parent shall have the sole right to control any audit or examination by any Tax authority, initiate any claim for refund or amend or file any Tax Return, and contest, resolve and defend against any assessment for additional Taxes, notice of Tax deficiency or other adjustment of Taxes of, or relating to, the income, assets or operations of the Company for all Tax periods.

Section 6.5. Tax Sharing Agreements. All Tax sharing agreements or similar agreements between the Company, on the one hand, and any of the Stockholders and their Affiliates, on the other hand, shall be terminated before the Closing Date, and, after the Closing Date, the Company shall not be bound thereby or have any Liability thereunder.

Section 6.6. Straddle Periods. For purposes of this Agreement, the portion of any Tax that relates to the portion of any Straddle Period ending on the Closing Date shall (a) in the case of real property, personal property and similar ad valorem Taxes be deemed to be the amount of such Tax for the entire Straddle Period multiplied by a fraction (i) the numerator of which is the number of days in the Straddle Period ending on the Closing Date and (ii) the denominator of which is the number of days in the entire Straddle Period and (b) in the case of any other Tax, be deemed equal to the amount which would be payable if the relevant Straddle Period ended on the Closing Date, provided that exemptions, allowances or deductions that are calculated on an annual basis, such as amortization and depreciation deductions (other than with respect to property placed into service after the Closing Date) shall be allocated on a per diem basis.

Section 6.7. Post-Closing Actions. None of Parent or its Affiliates shall, or shall cause or permit the Surviving Corporation to, unreasonably: (i) amend any Tax Return of the Company with respect to any Pre-Closing Tax Period, enter into any voluntary disclosure agreement, engage in any voluntary compliance procedures or make any other similar voluntary contact with any Tax authority with respect to any Tax Return or Tax of the Company for any Pre-Closing Tax Period, (ii) consent to the extension or waiver of the limitations period applicable to any Tax claim or assessment with respect to the Company for any Pre-Closing Tax Period, or (iii) make any Tax election with respect to the Company that has effect for any Pre-Closing Tax Period, if, in each case, such action could reasonably be expected to result in an amount for which indemnity may be sought under Article VII.

Section 6.8. Tax Reporting. Notwithstanding anything to the contrary contained herein, for purposes of determining the Company’s Taxes for any Pre-Closing Tax Period, including any Taxes arising out of or relating to the Taxable Spinout, and for purposes of determining the Tax consequences of the Taxable Spinout and the Merger to the Stockholders: (i) Parent, the Company, Spinout Company and each Stockholder shall treat the Spinout Stock received by such Stockholder as partial consideration for such Stockholder’s shares of Company Capital Stock in connection with the Merger for U.S. income Tax purposes, (ii) none of the Tax Returns of Parent, the Company, Spinout Company or any Stockholder shall reflect any position inconsistent with the Valuation, unless otherwise required by a Governmental Entity in connection with an audit or examination, it being understood and agreed that in the event the Valuation is challenged by any Governmental Entity, the Stockholders’ Representative shall have the right to assume the defense against any such challenge, (iii) any deductions attributable to payments of any Change of Control Payments, Company Transaction Expenses, Accrued Compensation or Deferred Compensation and any net operating losses of the Company shall be used to the fullest extent permitted by applicable Law to offset gain of the Company related to the Taxable Spinout (and in furtherance thereof, the Company shall make a closing-of-the-books election

pursuant to Treasury Regulations Section 1.382-6(b) unless requested otherwise by the Stockholders’ Representative), and (iv) the Company and Spinout Company shall make an election pursuant to Section 336(e) of the Code and any similar provision of state, local, or non-U.S. Tax laws in connection with the Company’s disposition of Spinout Stock.

Section 7.1. Survival of Representations and Covenants.

a.Survival. Subject to Section 7.1(d), the representations and warranties made by the Company in this Agreement shall survive the Effective Time until the first anniversary of the Closing Date (the date of expiration of such period, the “Survival Date”); provided, however, that, the representations and warranties made by the Company in Section 3.16(k), and the right to make indemnification claims in respect of such representations and warranties, shall survive until the sixth anniversary of the Closing Date (with all references herein to the “Survival Date” being understood to be references to, with regard to the representations and warranties made by the Company in Section 3.16(k), and the right to make indemnification claims in respect of such representations and warranties, the date of expiration of such six-year period); provided, further, that if, at any time on or before the Survival Date, any Indemnitee delivers to the Stockholders’ Representative a written notice alleging the existence of an inaccuracy in or a breach of, or a potential inaccuracy in or a potential breach of, any such representation or warranty and asserting facts reasonably expected to establish a claim for recovery under Section 7.2 based on such alleged inaccuracy or breach or potential inaccuracy or breach, then the relevant representation and warranty and claim for recovery shall survive the Survival Date solely with respect to such claim until such time as such claim is fully and finally resolved or withdrawn.

b.Parent Representations. All representations and warranties made by Parent and Merger Sub shall terminate and expire at the Effective Time, and any liability of Parent or Merger Sub with respect to such representations and warranties shall thereupon cease.

c.Survival of Covenants. All covenants and agreements of the parties hereto contained herein shall survive the Effective Time until fully waived in writing, performed or complied with.

d.Intentional Misrepresentation; Fraud. The limitations set forth in Section 7.1(a) and Section 7.1(b) shall not apply in the event of any intentional misrepresentation or fraud (as determined by a non-appealable and binding decision by a court of law having jurisdiction over the parties).

Section 7.2. Indemnification by the Stockholders.

a.Indemnification. From and after the Effective Time (but subject to Section 7.1 and Section 7.3), the Stockholders, severally but not jointly, shall hold harmless and indemnify each of the Indemnitees from and against, and shall compensate and reimburse each of the Indemnitees for, any Damages which are directly or indirectly suffered or incurred at any time by any of the Indemnitees or to which any of the Indemnitees may otherwise directly or indirectly become subject at any time (regardless of whether or not such Damages relate to any Third Party Claim) and which arise directly or indirectly from or as a result of, or are directly or indirectly connected with:

This Section 7.2(b) shall not, however, allow a duplicative recovery of the same Damages by Parent, on the one hand, and the Indemnitees other than Parent, on the other hand.

Section 7.3. Limitations.

a.Basket.

i.The Stockholders shall not be required to make any indemnification payment pursuant to Section 7.2(a)(i)-(vii) until such time as the total amount of all Damages that have been directly or indirectly suffered or incurred by any one or more of the Indemnitees, or to which any one or more of the Indemnitees has or have otherwise directly or indirectly become subject, exceeds $20,000 (the “Basket Amount”) in the aggregate. Once the total amount of such Damages exceeds the Basket Amount, then the Indemnitees shall be entitled to be indemnified and held harmless against and compensated and reimbursed for the entire amount of such Damages (subject to the Section 7.3(b) cap, if applicable), and not merely the portion of such Damages exceeding the Basket Amount.

ii.The limitation set forth in Section 7.3(a)(i) shall not apply (and shall not limit the indemnification or other obligations solely of the Stockholder or Stockholders that perpetuated such intentional misrepresentation or fraud) in the event of intentional misrepresentation or fraud (as determined by a non-appealable and binding decision by a court of law having jurisdiction over the parties).

b.Overall Liability Cap. Recourse by the Indemnitees under this Article VII shall be limited to an aggregate amount equal to the Additional Merger Consideration; provided, however, that the limitation set forth in this Section 7.3(b) shall not apply (and shall not limit the indemnification or other obligations solely of the Stockholder or Stockholders that perpetuated such intentional misrepresentation or fraud) in the event of intentional misrepresentation or fraud (as determined by a non-appealable and binding decision by a court of law having jurisdiction over the parties).

c.Qualifications. For purposes of Section 7.2(a), with respect to each representation, warranty, covenant or agreement contained in this Agreement that is subject to a “materiality,” “material,” “Company Material Adverse Effect,” “in all material respects” or similar qualification (but not including knowledge or Knowledge of the Company), any such qualification shall be disregarded for purposes for purposes of calculating the amount of any Damages that is subject to indemnification hereunder.

d.Representations Not Limited. The Company and the Stockholders agree that the Indemnitees’ rights to indemnification, compensation and reimbursement contained in this Article VII relating to the representations, warranties, covenants and obligations of the Company and the Stockholders are part of the basis of the bargain contemplated by this Agreement; and such representations, warranties, covenants and obligations, and the rights and remedies that may be exercised by the Indemnitees with respect thereto, shall not be waived, limited or otherwise affected by or as a result of (and the Indemnitees shall be deemed to have relied upon such representations, warranties, covenants or obligations notwithstanding) any knowledge on the part of any of the Indemnitees or any of their Representatives, regardless of whether obtained through any investigation by any Indemnitee or any Representative of any Indemnitee or through disclosure by the

Company or any other Person (other than by specific inclusion in the Company Disclosure Schedule), and regardless of whether such knowledge was obtained before or after the execution and delivery of this Agreement.

e.Special Rule. For avoidance of doubt: this Section 7.3 shall not apply to Section 7.2(a)(ix) or Section 7.2(a)(x).

f.No Double Recovery. If an Indemnitee’s claim under Section 7.2(a) based on a single nucleus of operative facts may be brought under different sections of Section 7.2(a), then such Indemnitee shall have the right to bring such claim under any applicable section it chooses in accordance with Section 7.2(a), provided, however, that in no event shall any Indemnitee be entitled to double recovery with respect to any particular incident, fact or event which resulted in Damages subject to indemnification under Section 7.2(a) regardless of whether there were breaches of more than one representation, warranty, covenant, agreement or otherwise.

Section 7.4. No Contribution. Each Stockholder waives, and each Stockholder acknowledges and agrees that such Stockholder shall not have and shall not exercise or assert (or attempt to exercise or assert), any right of contribution, right of indemnity or advancement of expenses or other right or remedy against Parent, the Surviving Corporation or the Company in connection with any indemnification obligation or any other Liability to which such Stockholder may become subject under or in connection with this Agreement or any other agreement, document, certificate or instrument delivered to Parent in connection with this Agreement. Effective as of the Closing, each Stockholder expressly waives and releases any and all rights of subrogation, contribution, advancement, indemnification or other claim against Parent, the Surviving Corporation or the Company. It is agreed, however, that this Section 7.4 shall not apply to indemnification rights of officers or directors of the Company as such, except in cases of bad faith or willful misconduct.

Section 7.5. Tax Limitations. Notwithstanding anything to the contrary contained herein, no Indemnitee shall have a claim for Damages under this Article VII with respect to: (i) the amount, value or condition of, or any Indemnitee’s ability to use after the Closing Date, any Tax attributes of the Company (and neither the Stockholders nor the Company are making nor shall be construed to have made any representation or warranty with respect to such matters), (ii) any Taxes resulting from any election by or at the direction of Parent under Section 338 of the Code (or any similar or analogous provision of applicable law) with respect to the transactions contemplated hereby, or (iii) any Taxes resulting from any action taken by Parent or the Company at the direction of Parent on the Closing Date after the Closing outside the ordinary course of business. There shall be no double-recovery of Damages under this Article VII to the extent of (and in respect of) the amount of Taxes that were taken into account in the calculation of Indebtedness, Change of Control Payments, Company Transaction Expenses, Current Liabilities, Accrued Compensation or Deferred Compensation.

Section 7.6. Defense of Third Party Claims.

a.In the event of the assertion or commencement by any Person, other than a party hereto, of any claim or Proceeding (whether against the Surviving Corporation, the Company, Parent or any other Person) with respect to which the Stockholders may become obligated to hold harmless, indemnify, compensate or reimburse any Indemnitee pursuant to this Article VII (a “Third Party Claim”), Parent shall have the right, at its election, to proceed with the defense of such Third Party Claim on its own with counsel reasonably satisfactory to the Stockholders’ Representative; provided, however, that the Stockholders’ Representative may retain separate co-counsel at its sole cost and expense and participate in the defense of such Third Party Claim or Proceeding. If Parent so proceeds with the defense of any such Third Party Claim:

i.subject to the other provisions of this Article VII, all reasonable expenses relating to the defense of such Third Party Claim shall be borne and paid exclusively by the Stockholders solely from the Additional Merger Consideration and any recoveries of such defense costs therefrom shall count against the liability cap set forth in Section 7.3(b);

ii.the Stockholders’ Representative shall use commercially reasonable efforts to make available to Parent any reasonably requested documents and materials in his, her or its and in the Stockholders’ possession or control that may be necessary to the defense of such Third Party Claim; and

iii.Parent may not settle, adjust or compromise such Third Party Claim without the consent of the Stockholders’ Representative (it being understood and agreed that if Parent requests that the Stockholders’ Representative consent to a settlement, adjustment or compromise, the Stockholders’ Representative shall not unreasonably withhold, condition or delay such consent; without limitation, withholding, delaying or conditioning such consent will not be deemed to be unreasonable if such settlement, adjustment or compromise does not provide full release of the claims raised against the respective Stockholders).

b.If Parent does not elect to proceed with the defense of any such Third Party Claim, the Stockholders’ Representative shall proceed with the defense of such Third Party Claim with counsel reasonably satisfactory to Parent; provided, however, that the Stockholders’ Representative may not settle, adjust or compromise any such Third Party Claim without the prior written consent of Parent (which consent may not be unreasonably withheld, conditioned or delayed; without limitation, withholding, delaying or conditioning such consent will not be deemed to be unreasonable if such settlement, adjustment or compromise does not provide full release of the claims raised against Parent and the Surviving Corporation). Parent shall give the Stockholders’ Representative prompt notice of the commencement of any such Third Party Claim against any Indemnitee and shall keep the Stockholders’ Representative reasonably informed at all stages thereof; provided, however, that any failure on the part of Parent to so notify the Stockholders’ Representative shall not limit any of the obligations of the Stockholders under this Article VII (except to the extent such failure materially prejudices the defense of such Third Party Claim).

Section 7.7. Indemnification Claim Procedure.

a.If any Indemnitee has or claims in good faith to have incurred or suffered, or believes in good faith that it may (pursuant to a Third Party Claim asserted or commenced before the Survival Date) incur or suffer, Damages for which it is or may be entitled to be held harmless, indemnified, compensated or reimbursed under this Article VII or for which it is or may be entitled to a monetary remedy (such as in the case of a claim based on fraud or intentional misrepresentation), such Indemnitee may deliver a notice of claim (a “Notice of Claim”) promptly, and in any case within 30 days’ of becoming aware of such claim, to the Stockholders’ Representative and, to the extent any Additional Merger Consideration remains, to Parent. Each Notice of Claim shall: (i) state that such Indemnitee believes in good faith that such Indemnitee is or may be entitled to indemnification, compensation or reimbursement under this Article VII or is or may otherwise be entitled to a monetary remedy; (ii) contain a brief description of the facts and circumstances supporting the Indemnitee’s claim; and (iii) contain a good faith, non-binding, preliminary estimate of the aggregate amount of the actual and potential Damages that the Indemnitee reasonably believes have arisen and may arise as a result of such facts and circumstances (the aggregate amount of such estimate, as it may be modified by such Indemnitee in good faith from time to time, being referred to as the “Claimed Amount”).

b.During the 20-day period commencing upon delivery by an Indemnitee to the Stockholders’ Representative of a Notice of Claim (the “Claim Dispute Period”), the Stockholders’

Representative may deliver to the Indemnitee who delivered the Notice of Claim and, to the extent any Additional Merger Consideration remains, to Parent a written response (the “Response Notice”) in which the Stockholders’ Representative: (i) agrees that the full Claimed Amount is owed to the Indemnitee; (ii) agrees that part, but not all, of the Claimed Amount (such agreed portion, the “Agreed Amount”) is owed to the Indemnitee; or (iii) in good faith indicates that no part of the Claimed Amount is owed to the Indemnitee. If the Response Notice is delivered in accordance with clause (ii) or (iii) of the preceding sentence, the Response Notice shall also contain a brief description of the facts and circumstances supporting the Stockholders’ Representative’s claim that only a portion or no part of the Claimed Amount is owed to the Indemnitee, as the case may be. Any part of the Claimed Amount that is not agreed to be owed to the Indemnitee pursuant to the Response Notice (or the entire Claimed Amount, if the Stockholders’ Representative asserts in the Response Notice that no part of the Claimed Amount is owed to the Indemnitee) is referred to in this Agreement as the “Contested Amount” (it being understood that the Contested Amount shall be modified from time to time to reflect any good faith modifications by the Indemnitee to the Claimed Amount). If no Response Notice is delivered before the expiration of the Claim Dispute Period, then the Stockholders shall be conclusively deemed to have agreed that the full Claimed Amount is owed to the Indemnitee.

c.If: (i) the Stockholders’ Representative delivers a Response Notice agreeing that the full Claimed Amount is owed to the Indemnitee; or (ii) the Stockholders’ Representative does not deliver a Response Notice during the Claim Dispute Period, then, within three Business Days following the receipt of such Response Notice by the Indemnitee (and, to the extent any Additional Merger Consideration remains, by Parent) or within three Business Days after the expiration of the Claim Dispute Period, as the case may be: (A) to the extent any Additional Merger Consideration remains, Parent shall release to the applicable Indemnitee from the Additional Merger Consideration an amount in cash equal to the full Claimed Amount (or such lesser amount as is then the remaining Additional Merger Consideration).

d.If the Stockholders’ Representative delivers a Response Notice during the Claim Dispute Period agreeing that less than the full Claimed Amount is owed to the Indemnitee, then within three Business Days following the receipt of such Response Notice by the Indemnitee (and, to the extent any Additional Merger Consideration remains, by Parent), to the extent any Additional Merger Consideration remains, Parent shall release to the applicable Indemnitee from the Additional Merger Consideration an amount in cash equal to the Agreed Amount (or such lesser amount as is the remaining Additional Merger Consideration).

e.If the Stockholders’ Representative delivers a Response Notice during the Claim Dispute Period indicating that there is a Contested Amount, the Stockholders’ Representative and the Indemnitee shall attempt in good faith to resolve the dispute related to the Contested Amount. If the Indemnitee and the Stockholders’ Representative resolve such dispute, a settlement agreement stipulating the amount owed to the Indemnitee (the “Stipulated Amount”) shall be signed by the Indemnitee and the Stockholders’ Representative; provided, that other than in the case of intentional misrepresentation or fraud (as determined by a non-appealable and binding decision by a court of law having jurisdiction over the parties), in no event shall the Stipulated Amount be greater than the then remaining Additional Merger Consideration. Within three Business Days following the execution of such settlement agreement, to the extent any Additional Merger Consideration remains, Parent shall pay to the applicable Indemnitee an amount in cash equal to the Stipulated Amount (or such lesser amount as is the remaining Additional Merger Consideration).

f.In the event that there is a dispute relating to any Notice of Claim or any Contested Amount (whether it is a matter between any Indemnitee, on the one hand, and the Stockholders, on the other hand, or it is a matter that is subject to a Third Party Claim brought against any Indemnitee) that remains

unresolved after application of the terms of Section 7.7(a)-(e), such dispute shall be settled in accordance with Section 8.10 hereof.

g.Notwithstanding the foregoing, nothing in this Section 7.7 shall increase or expand the indemnification obligations or liabilities of the Stockholders beyond the Additional Merger Consideration (except in the case of intentional misrepresentation or fraud, as determined by a non-appealable and binding decision by a court of law having jurisdiction over the parties, solely with respect to the Stockholder or Stockholders that perpetuated such intentional misrepresentation or fraud).

Section 7.8. Setoff. In addition to Section 7.7 and any rights of setoff or other similar rights that Parent or any of the other Indemnitees may have at common law or otherwise, Parent shall have the right to withhold and deduct from any sum that is or may be owed to any Stockholder hereunder: (a) any amount that is otherwise payable by any Stockholder to any Indemnitee under this Article VII or to Parent but has not yet been paid; and (b) pending final determination of such dispute (including any final determination under Section 2.10 or Section 7.7), any amount with respect to which there is a dispute as to whether such amount is payable by the Stockholder to any Indemnitee or to Parent under this Agreement.

Section 7.9. Exercise of Remedies Other Than by Parent. No Indemnitee (other than Parent, the Surviving Corporation or any successor thereto or assign thereof) shall be permitted to assert any indemnification claim or exercise any other remedy under this Agreement unless Parent, the Surviving Corporation or any successor thereto or assign thereof, as the case may be, shall have consented to the assertion of such indemnification claim or the exercise of such other remedy.

Section 7.10. Additional Merger Consideration Release.

a.If the remaining Additional Merger Consideration as of the Survival Date that exceeds the aggregate dollar amount, as of the Survival Date, of Claimed Amounts and Contested Amounts associated with all indemnification claims contained in any Notice of Claim that have not been finally resolved and paid before the Survival Date in accordance with Section 7.7 (each, an “Unresolved Additional Merger Consideration Claim” and the aggregate dollar amount of such Claimed Amounts and Contested Amounts as of the Survival Date being referred to as the “Pending Claim Amount”), then Parent shall, within three Business Days following the Survival Date, deliver an amount equal to such remaining Additional Merger Consideration minus the Pending Claim Amount to the Paying Agent (on behalf of and for distribution to the former Stockholders on a Pre-Preference-Satisfaction Pro Rata Share basis and/or, if and as applicable, on a Post-Preference-Satisfaction Pro Rata Share).

b.Following the Survival Date, if an Unresolved Additional Merger Consideration Claim is finally resolved, Parent shall, within three Business Days after the final resolution of such Unresolved Additional Merger Consideration Claim, deliver: (i) to the applicable Indemnitee an amount in cash determined in accordance with Section 7.7, if any, and (ii) to the Paying Agent (on behalf of and for distribution to the former Stockholders on a Pro Rata Share basis) an amount equal to the amount (if any) by which the remaining Additional Merger Consideration as of the date of resolution of such Unresolved Additional Merger Consideration Claim exceeds the then remaining Pending Claim Amount.

c.With regard to any Additional Merger Consideration (i.e., any post-Survival-Date Earnout Consideration) arising after the Survival Date, Section 7.10(a)-(b) shall be applied on each January 1, April 1, July 1 and each October 1 after the Survival Date as if such January 1, April 1, July 1 or such October 1 were the Survival Date – mutatis mutandis.

d.Notwithstanding anything to the contrary in this Agreement, if an Indemnitee delivers a Notice of Claim pursuant to the indemnity set forth in Section 7.2(a) for breaches of the representations and warranties made by the Company in Section 3.16(k), the payment of any applicable Additional Merger Consideration due shall not be withheld, setoff or delayed unless a third party has filed a Proceeding for the alleged infringement, misappropriation or similar claim, or the Indemnitee has filed a good faith declaratory judgment Proceeding against the third party with regard thereto, or the Indemnitee has agreed to a pre-Proceeding settlement with regard to the alleged infringement, misappropriation or similar claim. Nothing in this Section 7.10(d) shall affect in any way any Section 7.1(a) survival period or limit the ability of the Indemnitees to obtain indemnification for Damages in the aggregate amount specified in, and subject to, Section 7.3(b).

Section 7.11. Exclusive Remedy. Except: (a) for equitable relief, to which any party hereto may be entitled pursuant to this Agreement; (b) for Damages resulting from or arising out of fraud or intentional misrepresentation (as determined by a non-appealable and binding decision by a court of law having jurisdiction over the parties); and (c) as otherwise expressly provided in this Agreement, after the Effective Time the indemnification provided in this Article VII shall be the sole and exclusive remedy of the parties for monetary damages for any of the matters listed in Section 7.2(a) above, including, without limitation, any breach of any representation, warranty or covenant contained in this Agreement, but expressly excluding any intentional misrepresentation or fraud (as determined by a non-appealable and binding decision by a court of law having jurisdiction over the parties).

Section 7.12. Characterization of Payments. Any indemnity payments made pursuant to this Article VII shall constitute an adjustment to the Final Merger Consideration for Tax purposes and shall be treated as such by the parties to this Agreement and the Stockholders on their Tax Returns unless otherwise required by applicable law.

Section 8.1. Amendment and Modification. This Agreement may be amended, modified or supplemented in any and all respects by (but only by) written agreement of the parties hereto.

Section 8.2. Waiver.

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

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

Section 8.3. Notices. Any notice, request, approval, consent or other such communication required or permitted to be given under this Agreement shall be in writing and shall be deemed to have been sufficiently given if and only if delivered in person, by email or by internationally recognized overnight courier service to the party to which it is directed at its physical or email address shown below or such other physical or email address as such party shall have last given by such written notice to the other parties in accordance with this Section:

If sent by email, the date on which such notice, request, approval or consent shall be deemed delivered is the date of transmission, if such notice, request, approval or consent is sent via email to such email address before 5:00 p.m. at the location of receipt on a Business Day, or the first Business Day after the date of transmission, if such notice, request, approval or consent is sent via email to such email address at or after 5:00 p.m. at the location of receipt on a Business Day or on a day that is not a Business Day. If sent by internationally recognized overnight courier, the date on which such notice, request, approval or consent shall be deemed delivered is the next Business Day after the date of deposit with such courier (by the courier’s stated time for enabling next-business-day delivery), and if delivered after such stated time shall be deemed to be the second Business Day after the date of deposit.

Section 8.4. Counterparts. This Agreement may be executed in any number of counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed an original, but all of which shall be considered one and the same agreement, and shall become effective when each party has received counterparts signed by each of the other parties, it being understood and agreed that delivery of a signed counterpart signature page to this Agreement by electronic mail attachment in portable document format (“.pdf”) form, or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document shall constitute valid and sufficient delivery thereof.

Section 8.5. Entire Agreement; Third Party Beneficiaries.

a.This Agreement (including the documents and the instruments referred to herein) constitutes the entire agreement among the parties with respect to the subject matter of this Agreement and supersedes all prior and contemporaneous agreements and understandings, whether written and oral, among or between the parties (or among or between any set of the parties) with respect to the subject matter of this Agreement; provided, however, that any existing confidentiality agreement shall remain in effect until the Effective Time. None of the parties hereto have made any promises, representations, warranties, covenants, or undertakings, other than those expressly set forth herein, to induce the other parties to execute and deliver this Agreement, and each of the parties acknowledge that the other parties have not executed or delivered this Agreement in reliance upon any such promise, representation, or warranty, covenant or undertaking not contained herein.

b.Except for the rights of Stockholders, Indemnified D&Os and Indemnitees expressly set forth herein, nothing in this Agreement, express or implied, is intended to or shall confer upon any Person, other than the parties hereto and their respective successors and permitted assigns, any rights, benefits or remedies whatsoever.

Section 8.6. Severability. Any term, provision, covenant or restriction of this Agreement that is invalid, void or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms, provisions, covenants and restrictions hereof or the validity or enforceability of the offending term, provision, covenant or restriction in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term, provision, covenant or restriction hereof is invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit the term, provision, covenant or restriction, to delete specific words or phrases or to replace any invalid, void or unenforceable term, provision, covenant or restriction with a term, provision, covenant or restriction that is valid and enforceable and that comes closest to expressing the intention of the invalid, void or unenforceable term, provision, covenant or restriction, and this Agreement shall be enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to negotiate in good faith to replace such invalid, void or unenforceable term, provision, covenant or restriction with a valid and enforceable term, provision, covenant or restriction that will

achieve, to the extent possible, the economic, business and other purposes of such invalid, void or unenforceable term, provision, covenant or restriction.

Section 8.7. Governing Law. This Agreement, and all claims or causes of action (whether in contract, tort or statute) that may be based upon, arise out of or relate to the Merger or this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement or as an inducement to enter into this Agreement), shall be governed by and construed in accordance with the Laws of the State of Delaware (including in respect of statutes of repose or of limitations or other limitations period applicable to any state Law claim, controversy or dispute) that apply to agreements made and performed entirely within the State of Delaware, without regard to the conflicts of law provisions thereof or of any other jurisdiction. Each party hereto agrees and acknowledges that the application of the Laws of the State of Delaware is reasonable and appropriate based upon the parties’ respective interests and contacts with the State of Delaware.

Accordingly, the terms and provisions of this Agreement shall be interpreted and construed in accordance with their usual and customary meanings, and each of the parties hereto hereby waives the application in connection with the interpretation and construction of this Agreement of any Law to the effect that ambiguous or conflicting terms or provisions contained in this Agreement shall be interpreted or construed against the party whose attorney prepared the executed draft or any earlier draft of this Agreement.

The parties hereto agree that if any of the provisions of this Agreement were not to be performed as required by their specific terms or were to be otherwise breached, irreparable damage will occur to the other parties, no adequate remedy at law would exist and damages would be difficult to determine.

Section 8.14. Conflict Waiver. Recognizing that Wilson Sonsini Goodrich & Rosati, P.C. (“WSGR”) has acted as legal counsel to certain of the Stockholders and the Company and its affiliates in connection with the transactions contemplated by this Agreement, and that WSGR may act as legal counsel to certain of the Company’s Stockholders after the Closing, each of Parent, Merger Sub and the Surviving Corporation hereby waives, on its own behalf and agrees to cause its Affiliates to waive, any conflicts that may arise in connection with WSGR representing any such Stockholders and/or its Affiliates after the Closing as such representation may relate to the transactions contemplated herein. In addition, all communications involving attorney-client confidences between any Stockholders and its Affiliates in the course of the negotiation, documentation and consummation of the transactions contemplated hereby shall be deemed to be attorney-client confidences that belong solely to such Stockholders and their Affiliates (and not the Company). Accordingly, the Company shall not have access to any such communications, or to the files of WSGR relating to such engagement, whether or not the Closing shall have occurred. Without limiting the generality of the foregoing, upon and after the Closing, (a) the applicable Stockholders and their Affiliates (and not the Company) shall be the sole holders of the attorney-client privilege with respect to such engagement, and the Company shall not be a holder thereof, (b) to the extent that files of WSGR in respect of such engagement constitute property of the client, only the applicable Stockholders and their Affiliates (and not the Company) shall hold such property rights and (c) WSGR shall have no duty whatsoever to reveal or disclose any such attorney-client communications or files to the Company by reason of any attorney-client relationship between WSGR and the Company. WSGR shall be a third-party beneficiary to this Agreement, solely with respect to this Section 8.14.

IN WITNESS WHEREOF, the Company, Parent, Merger Sub and the Stockholders’ Representative have caused this Agreement and Plan of Merger to be executed and delivered on the date first set forth above.
