The Letter of Transmittal may, in Parent’s discretion, require that the holder of each Certificate acknowledge the provisions of Section 2.17 as a condition to receipt of the Merger Consideration Shares payable to such holder.

(b) Upon the surrender to the Exchange Agent of its Certificate or Certificates (in the case of holders of Company Preferred Stock or Company Common Stock), accompanied by a properly completed Letter of Transmittal, (i) a holder of Company Preferred Stock or Company Common Stock will be entitled to receive promptly after the Effective Time (A) a certificate or certificates representing that whole number of shares of Parent Common Stock such holder has the right to receive pursuant to Section 2.8 in such denominations and registered in such names as such holder may request, and (B) a check representing any cash in lieu of fractional shares to be issued or paid in consideration therefor in respect of the shares of Company Preferred Stock or Company Common Stock represented by its Certificate or Certificates, and (ii) a holder of Company Options will be entitled to receive promptly after the Effective Time the portion of the Closing Merger Consideration (if any) applicable to such holder’s Company Options.

Participant will be entitled to receive promptly after the Effective Time the portion of the Closing Merger Consideration (if any) applicable to such individual’s interest in the Bonus Plan Pool. No interest will be paid or accrued on the pro rata portion of the Closing Merger Consideration or the cash in lieu of fractional shares, if any, and unpaid dividends and distributions, if any, payable to a holder of Company Preferred Stock or Company Common Stock or Company Options or a Bonus Plan Participant. Until so surrendered, each such Certificate for shares shall represent after the Effective Time, for all purposes, only the right to receive, without interest, the pro rata portion of the Closing Merger Consideration payable to the holder of such Certificate and any cash in lieu of fractional shares to be issued or paid in consideration therefor upon surrender of such Certificate in accordance with, and any dividends or distributions to which such holder is entitled pursuant to, this Article 2.

(c) No dividends or other distributions with respect to Parent Common Stock shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Parent Common Stock represented thereby, in each case unless and until the surrender of such Certificate in accordance with this Article 2. Subject to the effect of applicable abandoned property, escheat or similar laws, following surrender of any such Certificate in accordance with this Article 2, the record holder thereof shall be entitled to receive, without interest, (i) the amount of dividends or other distributions with a record date after the Effective Time theretofore payable with respect to the whole shares of Parent Common Stock represented by such Certificate and not paid and/or (ii) at the appropriate payment date, the amount of dividends or other distributions payable with respect to shares of Parent Common Stock represented by such Certificate with a record date after the Effective Time (but before such surrender date) and with a payment date subsequent to the issuance of the Parent Common Stock issuable with respect to such Certificate.

(d) Anything to the contrary contained in this Agreement notwithstanding, no fractional shares of Parent Common Stock shall be issued upon the surrender of Certificates for exchange, no dividend or distribution with respect to Parent Common Stock shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a stockholder of Parent. In lieu of the issuance of any such fractional share, Parent shall pay to each former stockholder of the Company who otherwise would be entitled to receive such fractional share an amount in cash (rounded to the nearest cent) determined by multiplying (i) the average, rounded to the nearest one one-hundredth, of the closing sale prices of Parent Common Stock on the NASDAQ Global Market (the “NASDAQ”) (or such other primary stock exchange on which the Parent Common Stock is then listed) for the ten trading days immediately preceding the date of the Effective Time by (ii) the fraction of a share (after taking into account all shares of Company Preferred Stock and Company Common Stock and all Company Options held by such holder at the Effective Time and rounded to the nearest hundredth when expressed in decimal form) of Parent Common Stock to which such holder would otherwise be entitled to receive pursuant to Section 2.8.

(e) Any portion of the Exchange Fund that remains unclaimed by the stockholders of the Company as of the twelve month anniversary of the Effective Time may, at Parent’s option, be paid to Parent. In such event, any former stockholders or option holders of the Company who have not theretofore complied with this Article 2 shall thereafter look only to Parent with respect to the portion

-31-

of the Closing Merger Consideration payable to such holders, any cash in lieu of any fractional shares and any unpaid dividends and distributions on the Parent Common Stock deliverable in respect of each share of Company Preferred Stock or Company Common Stock such stockholder holds as determined pursuant to this Agreement. The Exchange Agent will notify Parent prior to the time that any portion of the Exchange Fund that remains unclaimed would have to be delivered to a public official pursuant to applicable abandoned property, escheat or similar laws and, at Parent’s option, such portion shall be paid to Parent. Notwithstanding the foregoing, none of Parent, the Surviving Corporation, the Exchange Agent or any other person shall be liable to any former holder of shares of Company Preferred Stock or Company Common Stock or of Company Options for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

(f) In the event 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 and, if reasonably required by Parent or the Exchange Agent, an indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the applicable portion of the Merger Consideration payable to such claimant, deliverable in respect thereof pursuant to this Agreement.

(g) The Exchange Agent shall invest any cash included in the Exchange Fund, as directed by Parent, on a daily basis.

Section 2.12 Indemnification Escrow.

(a) On the Closing Date, Parent shall deposit the Escrow Shares with an escrow agent to be mutually agreed among the Holder Representative and Parent (the “Escrow Agent”) to be held in escrow to serve as the sole source of payment of claims for indemnification pursuant to Article 9.

Section 2.13 Effect of Transaction on Company Stock Options. At the Effective Time, each Company Option then outstanding and exercisable shall, automatically and without further action on behalf of the holder thereof, be deemed to have been canceled and converted as of immediately prior to the Effective Time into the right to receive a number of Merger Consideration Shares, if any, as would have been issuable had the then-vested portion (after taking into account any accelerated vesting rights) of any Company Options been exercised on a net exercise basis immediately before the Effective Time.For the avoidance of doubt, any vested Company Option with a per share exercise price equal to or in excess of the Common Stock Remaining Amount Per Share shall, automatically and without further action on behalf of the holder thereof, be automatically canceled as of the Effective Time pursuant to this Section 2.13 and shall not be entitled to any payment of consideration therefor. At or prior to the Effective Time, the Company’s Board of Directors shall pass such resolutions as may be necessary to effectuate the provisions of this Article 2 with respect to Company Options and to ensure that: (A) all Company Options are canceled as of immediately prior to the Effective Time and (B) neither any holder of any Company Option, nor any other participant in a Company Benefit Plan, shall have any right thereunder, except as provided in this Article 2. Prior to the Effective Time, the Company shall deliver to each holder of Company Options appropriate notices setting forth the terms applicable to such Company Options with respect to the transactions contemplated by this Agreement (including the Merger). The installment payments received by a holder of a Company Option under this Section 2.13 are intended to be separate “payments” for purposes of Section 409A of the Code and the guidance and regulations thereunder.

Section 2.14 Release of Indemnity Escrow; Additional Shares.

(a) On the date that is the first anniversary of the Closing Date (the “Indemnity Escrow Release Date”), Parent shall provide the Holder Representative with (i) a written notice of its reasonable and good-faith determination of the Projected Indemnity Amount, together with reasonable supporting calculations and documentation, and (ii) a written notice duly executed by Parent instructing the Escrow Agent to pay to the Exchange Agent, for further distribution to the Escrow Participating Holders, and in accordance with the terms of the Escrow Agreement, the excess of (x) the shares of Parent Common Stock in the Indemnity Escrow Account and (y) the Projected Indemnity Amount so reasonably determined in good-faith by Parent (such amount, the “Indemnity Escrow Initial Release Amount”). The term “Projected Indemnity Amount” means the (w) sum of Losses that, as of the Indemnity Escrow Release Date, would reasonably be expected to be indemnified by the Indemnity Escrow Account pursuant to Article 9 in respect of claims that have been timely asserted but not finally resolved by such date, divided by (z) the Twenty Day Average for the Indemnity Escrow Release Date.

(b) As and to the extent any claim described in clause (a) above is resolved in favor of the Escrow Participating Holders, Parent and the Holder Representative shall direct the Escrow Agent to deliver to the Exchange Agent, for further distribution to the Escrow Participating Holders the related portion of the remaining number of shares of Parent Common Stock in the Indemnity Escrow Account as provided in the Escrow Agreement (each such portion, an “Indemnity Escrow Subsequent Release Amount”).

-33-

(c) Within three (3) Business Days of receipt of any amount required to be delivered by the Escrow Agent to the Exchange Agent, for further distribution to each Escrow Participating Holder who has surrendered before the Indemnity Escrow Release Date his, her or its Certificates (if applicable) and duly executed Letter of Transmittal, pro rata in accordance with the Escrow Participating Holders’ relative Escrow Percentages, the Indemnity Escrow Initial Release Amount or Indemnity Escrow Subsequent Release Amount, as applicable.

(d) On the Indemnity Escrow Release Date, Holder Representative shall provide Parent with a written notice of its reasonable and good-faith determination of the number of Parent Indemnity Shares together with reasonable supporting calculations and documentation, and Parent shall issue to the Exchange Agent, for further distribution to the Escrow Participating Holders the number Parent Indemnity Shares so reasonably determined in good-faith by the Holder Representative. The term “Parent Indemnity Shares” means the number of shares of Parent Common Stock equal to (x) the sum of Losses indemnifiable pursuant to Section 9.2(b) for the period from the Closing until the Indemnity Escrow Release Date, (y) divided by the Twenty Day Average for the Indemnity Escrow Release Date. The Holder Representative shall provide written notice to Parent of its reasonable and good-faith determination of each Loss indemnifiable pursuant to Section 9.2(b) and incurred following the Indemnity Escrow Release Date (each such Loss, a “Parent Additional Loss”) no later than thirty (30) days following the occurrence of such Parent Additional Loss, and Parent shall issue to the Exchange Agent an amount of shares of Parent Common Stock (each such share, a “Parent Additional Indemnity Share”) equal to (x) the Parent Additional Loss so reasonably determined in good-faith by Holder Representative divided by (y) the Twenty Day Average for the date of such issuance. Within three (3) Business Days of receipt of any Parent Indemnity Shares or Parent Additional Indemnity Shares, the Exchange Agent will pay to each Holder Indemnitee who has surrendered before the Indemnity Escrow Release Date his, her or its Certificates (if applicable) and duly executed Letter of Transmittal, pro rata in accordance with the Holder Indemnitee’s Losses indemnifiable pursuant to Section 9.2(b), the Parent Indemnity Shares or the Parent Additional Indemnity Shares, as applicable.

Section 2.15 Post-Closing Adjustment.

(a) No later than the 60^th day following the Closing Date, Parent will cause to be prepared and delivered to the Holder Representative (i) a statement setting forth its calculation of Closing Working Capital, which statement shall contain a consolidated balance sheet of the Company as of the Closing Date or, if the Closing occurs after January 31, 2013, a consolidated balance sheet of the Company as of January 31, 2013 (without giving effect to the transactions contemplated herein), a calculation of Closing Working Capital (the “Closing Working Capital Statement”) and a certificate of Parent that the Closing Working Capital Statement was prepared in accordance with Accounting Principles, and (ii) a statement setting forth its calculation of the Company Fees, together with reasonable supporting detail, including all invoices, bills and engagement letters received by the Company.

(b) The post-closing adjustment shall equal (x) the Closing Adjustment Amount minus (y) the Post-Closing Adjustment Amount (the “Post-Closing Adjustment”). If the Post-Closing Adjustment is a negative number, the Holder Representative and Parent

-34-

shall within three (3) Business Days of the final determination of the Post-Closing Adjustment (the date of such final determination, the “Post-Closing Escrow Date”) issue joint written instructions directing the Escrow Agent (A) to pay to Parent from the Indemnity Escrow Account an amount of shares of Parent Common Stock equal to (x) the absolute value of the Post-Closing Adjustment divided by (y) the Twenty Day Average for the Post-Closing Escrow Date. Any payments to be made to Parent pursuant to this Section 2.15(b) shall be made first from the Indemnity Escrow Account and, for the avoidance of doubt, shall not be subject to the Parent De Minimis Amount, Parent Threshold or other indemnification limitations set forth in Section 9.4.

(i) The “Post-Closing Adjustment Amount” means the greater of (1) zero and (2) the sum of (x) the Post-Closing Working Capital Adjustment and (y) the Post-Closing Company Fees Adjustment, in each case, divided by (z) the Twenty Day Average for the Post-Closing Escrow Date.

(ii) The “Post-Closing Working Capital Adjustment” shall be an amount equal to the Target Working Capital minus the Closing Working Capital; provided, however, that after receipt of the Closing Working Capital Statement, the Holder Representative shall have 30 days to review the Closing Working Capital Statement (the “Post-Closing Review Period”), and Parent shall consider in good faith any errors asserted by the Holder Representative during the Post-Closing Review Period in the calculation of the Closing Working Capital Statement about which the Holder Representative notifies Parent and, unless it is in reasonable disagreement with any such asserted errors, Parent shall appropriately adjust the Closing Working Capital Statement and Post-Closing Working Capital Adjustment to reflect such corrections.

(iii) The “Post-Closing Company Fees Adjustment” shall mean an amount equal to the Company Fees minus the Target Company Fees.

Section 2.16 Withholding Rights. Each of the Exchange Agent, the Escrow Agent, Parent and the Surviving Corporation shall be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement or the Escrow Agreement such amounts as it is 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 amounts are so withheld by the Exchange Agent, the Escrow Agent, Parent or the Surviving Corporation, as the case may be, and paid to the appropriate Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement and the Escrow Agreement as having been paid to the person in respect of whom such deduction and withholding was made. The parties agree to use commercially reasonable efforts to minimize or eliminate withholding Taxes to the extent permitted by applicable Law, provided, however, that neither Parent nor Merger Sub shall be required to take any action, and any other party shall not be permitted to take any action pursuant to this last sentence of this Section 2.15, that could (i) cause Parent or Merger Sub to incur any incremental direct or indirect cost or liability (including any liability for Taxes) or (ii) result in a delay of the Closing.

-35-

Following the 180-day anniversary of the Closing Date, all or any portion of the Restricted Securities may be Transferred by a holder without restriction under this Section 2.17. Anything to the contrary notwithstanding, (i) any holder may sell or otherwise transfer any Merger Consideration Shares to an Immediate Family Member, to a trust for the benefit of such family member or to such holder’s heirs after the Closing; (ii) any holder that is a partnership or limited liability company may transfer Merger Consideration Shares to one or more partners, members or Affiliated Business Entities after the Closing; (iii) any Stockholder that is a trust may transfer shares of Merger Consideration Shares after the Closing to the beneficiary of the trust upon the trust’s maturity; and (iv) any holder may transfer Merger Consideration Shares to another holder after the Closing, in each case subject to compliance with Applicable Law; provided, that each transferee agrees in writing to be bound by all of the provisions of this Section 2.17.

Section 3.3 Authority.

(a) The Company has all requisite power and authority to execute and deliver this Agreement and the Ancillary Agreements to which it is a party and to perform its obligations hereunder and thereunder and, subject to receipt of the Company Stockholder Approval, to consummate the transactions contemplated hereby and thereby, all of which have been duly authorized by all necessary action on the part of the Company. The Board of Directors of the Company has determined unanimously that this Agreement is advisable and in the best interests of the Company and its stockholders and has directed that this Agreement be submitted to the Company’s stockholders and noteholders for approval and adoption and has adopted a resolution to the foregoing effect. The Bridge Loan Approval has been obtained. Other than the Company Stockholder Approval and the Bridge Loan Approval, no vote of the holders of Company Common Stock, Company Preferred Stock, Bridge Loan Notes or any other security of the Company is required to approve this Agreement or the Ancillary Agreements or for the Company to consummate the transactions contemplated hereby and thereby. The Covered Shares Beneficially Owned or held by the Voting Agreement Stockholders collectively represent sufficient voting power to obtain, and will have the effect of assuring the receipt of, Approval A, Approval B and Approval C, and to cause the Drag-Along Right to be triggered, in each case without the vote or consent of any other security holders of the Company. The Covered Shares Beneficially Owned or held by the Voting Agreement Stockholders, together with the shares of Company Common Stock subject to the Drag-Along Right, represents sufficient voting power to obtain, and will have the effect of assuring receipt of, Approval D. Accordingly, assuming compliance by the Stockholders with Article 2 of the Voting Agreement, receipt of the Company Stockholder Approval is assured. No other proceeding on the part of the Company, and no vote, consent or approval of any holder of any securities of the Company (or class or series thereof), whether under the Governing Documents of the Company or any other agreement, arrangement or understanding, or any applicable Law, is necessary to authorize, adopt or execute this Agreement and the Ancillary Agreements to which the Company is a party or to consummate the transactions contemplated hereby and thereby. The Company has duly executed and delivered this Agreement and, at or prior to the Closing will have duly executed and delivered the Ancillary Agreements to the extent a party thereto. This Agreement constitutes and, upon due execution and delivery, each of the Ancillary Agreements, to the extent the Company is a party thereto, will constitute, a valid, legal and binding agreement of the Company (assuming that this Agreement and the Ancillary Agreements have each been duly and validly authorized, executed and delivered by the other parties thereto), enforceable against the Company in accordance with their respective terms, except to the extent that enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other Laws affecting the enforcement of creditors’ rights generally.

(b) The Company Voting Agreement is in full force and effect and has not been amended in a manner that is detrimental to Parent’s interests, including Parent’s interest in obtaining the Company Stockholder Approval. There is no agreement or understanding that would prevent or disable the effectiveness of the Drag-Along Right or restrict the ability of the Stockholders (as

-39-

defined in the Voting Agreement) to exercise the Drag-Along Right. The Company has obtained the Senior Preferred Director Approval, which, together with the approval of this Agreement by the aggregate number and type of Company securities that are subject to the Voting Agreement and are beneficially owned or held by the Stockholders, will trigger the Drag-Along Right, including obligating the Company to provide the Drag-Along Notice (as defined in the Company Voting Agreement). The Merger is an “Approved Transaction,” as defined in the Company Voting Agreement, and the Stockholders constitute the “Requisite Holders” for purposes of Section 4.2 of the Company Voting Agreement. Holders of the Company’s Common Stock that are parties to the Company Voting Agreement and subject to and bound by the Drag-Along Right hold and beneficially own voting power with respect to not less than two-thirds (2/3) of the outstanding Company Common Stock. None of the Merger or the transactions contemplated by this Agreement will fall under any of the exceptions to the Drag-Along Right set forth in Section 4.4 of the Company Voting Agreement. Upon the exercise of the Drag-Along Right by the Stockholder, as set forth in Section 2.1(a)(iii) of the Voting Agreement, the Company shall provide the Drag-Along Notice to the holders of the Company’s Common Stock.

The term “Superior Proposal” means any bona fide written offer made by a third party that if consummated would result in such Person (or its stockholders) owning, directly or indirectly, (i) in the case of Parent, more than 50% of the shares of Parent Common Stock then outstanding (or of the shares of the surviving entity in a merger or the direct or indirect parent of the surviving entity in a merger) or more than 50% of the assets of Parent, in each case the consummation of which would require the termination of this Agreement, or (ii) in the case of the Company, all of the shares of Company Common Stock and Company Preferred Stock then outstanding (or of the shares of the surviving entity in a merger or the direct or indirect parent of the surviving entity in a merger) or all or substantially all the assets of the Company, and in the case of each of Parent and the Company, which the Board of Directors of Parent or the Company, as applicable, reasonably determines (after consultation with its outside legal advisors and a financial advisor of nationally recognized reputation and taking into account all financial, legal, regulatory and other aspects of such proposal and the Person making the proposal) to be (i) more favorable to the stockholders of Parent or the Company, as applicable, than the transactions contemplated by this Agreement (after giving effect to any changes to this Agreement proposed by the Company or Parent, as applicable, in response to such offer or otherwise) and (ii) reasonably capable of being completed on the terms set forth in the proposal.

(b) Prior to the later of (i) the closing of the Parent Equity Offering and (ii) the receipt of the Parent Stockholder Approval, the Board of Directors of Parent shall not make a Change in the Parent Recommendation, and neither the Board of Directors of Parent nor Company shall approve, adopt or recommend, or publicly propose to approve, adopt or recommend, or allow Parent or Company, as applicable, or any of its Subsidiaries to enter into, a merger agreement, letter of intent, agreement in principle, share purchase agreement, asset purchase agreement, share exchange agreement, option agreement or other similar contract (other than a confidentiality agreement referred to in Section 6.4(a)) or any tender offer providing for, with respect to, or in connection with, any Takeover Proposal (and, in the case of Parent, any Acquisition Proposal). The foregoing notwithstanding, at any time prior to obtaining the later of (i) the closing of the Parent Equity Offering and (ii) the receipt of the Parent Stockholder Approval and subject to compliance with Section 6.4 and Section 6.4(c), the Board of Directors of Parent may make a Change in the Parent Recommendation (and, in connection therewith in the case of a Superior Proposal, may take actions referred to in Section 6.4(a)(iv)) in response to a Superior Proposal if the Board of Directors of Parent concludes in good faith, after consultation with outside legal advisors, that the failure to take such action would be inconsistent with its fiduciary duties under applicable Law. The foregoing notwithstanding, at any time prior to the later of (i) the closing of the Parent Equity Offering and (ii) the receipt of the Parent Stockholder Approval, the Company may in response to a Superior Proposal take actions referred to in Section 6.4(a)(iv) (subject to compliance with Section 6.4 and Section 6.4(c)), to the extent that the Board of Directors of Company determines that this Agreement is no longer advisable and either makes no recommendation or recommends that its stockholders reject this Agreement in response to

-72-

a Superior Proposal, if the Board of Directors of the Company concludes in good faith, after consultation with outside legal advisors, that the failure to take such action would be inconsistent with its fiduciary duties under applicable Law.

Parent or the Company, as applicable, shall provide to Parent on a reasonably prompt basis (and in any event within 48 hours) of any material modifications to the terms of any such Takeover Proposal. Parent or the Company, as applicable, shall not, and shall cause its Subsidiaries not to, enter into any contract with any Person subsequent to the date of this Agreement, and neither Parent or the Company, as applicable, nor any of its Subsidiaries is party to any contract, in each case, that prohibits Parent or the Company, as applicable from providing such information to the Company or Parent, as applicable.

(b) For purposes of vesting, eligibility to participate and accrual of benefits under the employee benefit plans of Parent and its Subsidiaries providing benefits to any Company Employees after the Closing Date (including the Company Benefit Plans) (the “New Plans”), each Company Employee shall be credited with his or her years of service with the Company and its Subsidiaries before the Closing Date, to the same extent as such Company Employee was entitled, before the Closing Date, to credit for such service under any similar Company or Company Subsidiary employee benefit plan in which such Company Employee participated or was eligible to participate immediately prior to the Closing Date, provided that the foregoing shall not apply (i) with respect to benefit accrual under any defined benefit pension plan, (ii) for purposes of any New Plan under which similarly-situated employees of Parent and its Subsidiaries do not receive credit for prior service, (iii) for purposes of any New Plan that is grandfathered or frozen, either with respect to level of benefits or participation or (iv) to the extent that its application would result in a duplication of benefits with respect to the same period of service. In addition, and without limiting the generality of the foregoing, to the extent legally permissible, (i) each Company Employee shall be immediately eligible to participate, without any waiting time, in any and all New Plans to the extent coverage under such New Plan is replacing comparable coverage under a Company Benefit Plan in which such Company Employee participated immediately before the Closing Date (such plans, collectively, the “Old Plans”), and (ii) for purposes of each New Plan providing medical, dental, pharmaceutical, life insurance and/or vision benefits to any Company Employee, Parent shall, or shall cause the Surviving Corporation to, cause all pre-existing condition exclusions and actively-at-work requirements of such New Plan to be waived for such employee and his or her covered dependents, unless such conditions would not have been waived under the comparable Old Plans of the Company or its Subsidiaries in which such employee participated immediately prior to the Closing Date and (iii) Parent shall, or shall cause the Company to, cause any eligible expenses incurred by such employee and his or her covered dependents during the portion of the plan year of the Old Plan ending on the date such employee’s participation in the corresponding New Plan begins to be taken into account under such New Plan for purposes of satisfying all deductible, coinsurance, maximum out-of-pocket and lifetime maximum limitations or requirements applicable to such employee and his or her covered dependents for the applicable plan year as if such amounts had been paid in accordance with such New Plan.

(a) Parent agrees that, until the six year anniversary date of the Effective Time, the Surviving Corporation’s Governing Documents shall contain provisions no less favorable with respect to indemnification of the current and former directors and officers of the Company (the “Covered Persons”) than are currently provided in the Company’s Governing Documents, which provisions shall not be amended, repealed or otherwise modified in any manner that would adversely affect the rights thereunder of any such individuals until the expiration of the statutes of limitations applicable to such matters or unless such amendment, modification or repeal is required by applicable Law.

(b) Without limiting the provisions of Section 6.11(a), until the six (6) year anniversary of the Effective Time, the Surviving Corporation shall (i) indemnify and hold harmless each Covered Person against and from any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, to the extent such claim, action, suit, proceeding or investigation arises out of or pertains to (A) any action or omission or alleged action or omission in such Covered Person’s capacity as such or (B) this Agreement and any of the transactions contemplated hereby and (ii) pay in advance of the final disposition of any such claim, action, suit, proceeding or investigation the expenses (including reasonable attorneys’ fees) of any Covered Person upon receipt of an undertaking by or on behalf of such Covered Person to repay such amount if it shall ultimately be determined that such Covered Person is not entitled to be indemnified. Neither Parent nor the Surviving Corporation shall (and Parent shall cause the Surviving Corporation not to) settle or compromise or consent to the entry of any judgment or otherwise terminate any claim, action, suit, proceeding or investigation of a Covered Person for which indemnification may be sought under this Section 6.11(b) unless such settlement, compromise, consent or termination includes an unconditional release of such Covered Person from all liability arising out of such claim, action, suit, proceeding or investigation.

-78-

(c) Parent shall use its reasonable best efforts (and Company shall cooperate prior to the Effective Time in these efforts) to maintain in effect for a period of six (6) years after the Effective Time Company’s existing directors’ and officers’ liability insurance policy (provided that Parent may substitute therefor (i) policies of at least the same coverage and amounts containing terms and conditions which are substantially no less advantageous or (ii) with the consent of Company given prior to the Effective Time, any other policy with respect to claims arising from facts or events which occurred prior to the Effective Time and covering persons who are currently covered by such insurance; provided that Parent shall not be obligated to make aggregate annual premium payments for such six (6)-year period in respect of such policy (or coverage replacing such policy) which exceed 150% of the annual premium payments on Company’s current policy in effect as of the date of this Agreement (the “Maximum Amount”). If the amount of the premiums necessary to maintain or procure such insurance coverage exceeds the Maximum Amount, Parent shall use its reasonable best efforts to maintain the most advantageous policies of directors’ and officers’ liability insurance obtainable for a premium equal to the Maximum Amount. In lieu of the foregoing, either Parent or the Company may obtain on or prior to the Effective Time, a prepaid tail policy; provided that the cost of such policy does not exceed 150% of the Maximum Amount.

(d) This Section 6.11(d) shall survive the consummation of the Merger and is intended to benefit, and shall be enforceable by, any Person or entity referred to in clause (a) of this Section 6.11 (whether or not parties to this Agreement).

If Parent terminates this Agreement pursuant to Section 8.2(b) effective prior to the April Rolling Payment Date, then on the next Rolling Payment Date, Parent shall advance the Company a pro rata portion of the applicable Rolling Advance with respect to the immediately following Rolling Payment Date, which portion shall be equal to the Rolling Advance for such Rolling Payment Date multiplied by a fraction, the numerator of which is thirty (30) minus the number of days between such Rolling Payment Date and the date Parent terminated the Agreement, and the denominator of which is thirty (30).

(iv) Anything to the contrary notwithstanding, Parent may reduce the size of a 2013 Advance payable to the Company if such 2013 Advance would otherwise exceed $2,000,000 individually or if the aggregate of such 2013 Advance and all prior 2013 Advances made by Parent pursuant to the 30-Day Funding Obligation would otherwise exceed $6,000,000.

The Company shall deliver its good faith preliminary 3-Month Budget to Parent no later than December 1, 2012 and shall deliver an updated preliminary 3-Month Budget to Parent no later than January 1, 2013 that in good faith takes into account comments from Parent on the preliminary budget.

Holders, the Holder Representative and Parent also shall, and shall cause their respective Affiliates to, make available to each other, as reasonably requested and available, personnel responsible for preparing, maintaining and interpreting information and documents relevant to Taxes. Any information or documents provided pursuant to this Section 6.16(b) shall be kept confidential by the Party receiving the information or documents, except (x) as may otherwise be necessary in connection with the filing of Tax Returns or in connection with any administrative or judicial proceedings relating to Taxes, or (y) as required by law or to employees, advisors or consultants of the Holder Representative and to the Escrow Participating Holders, in each case who have a need to know such information, provided that such persons either (A) agree to observe the terms of this Section 6.16(b) or (B) are bound by obligations of confidentiality to the Holder Representative of at least as high a standard as those imposed on the Holder Representative under this Section 6.16(b). Anything in this Agreement to the contrary notwithstanding, neither Parent nor any of its Subsidiaries shall be required to provide to any person any Tax Return (or copy thereof) of Parent or any consolidated, combined or unitary group that includes Parent or any of its Subsidiaries.

(c) Parent shall have the exclusive right to control any audit, litigation or other proceeding with respect to Taxes (a “Tax Contest”), provided, however, that with respect to any Tax Contest for any Pre-Closing Tax Period which Tax Contest includes any issue for which Parent Indemnitee is entitled to indemnification under Section 9.2(a), (i) Parent shall keep the Holder Representative reasonably informed with respect to such defense, (ii) Parent shall consult with the Holder Representative before taking any significant action in connection with such Tax Contest, and (iii) the Holder Representative shall have the right to approve any settlement of such Tax Contest (such approval not to be unreasonably delayed or withheld).

(e) All Tax Sharing Agreements with respect to or involving the Company or any of its Subsidiaries shall be terminated as of the Closing, and neither the Company nor any of its Subsidiaries shall have any obligation or liability pursuant thereto. A “Tax Sharing Agreement” shall mean an agreement binding the Company or any of its Subsidiaries that provides for the allocation, apportionment, sharing or assignment of any Tax liability or benefit; provided, however, that the following agreements shall be disregarded: (i) commercially reasonable agreements not primarily relating to Taxes providing for the customary allocation or payment of real property Taxes attributable to real property leased or occupied by the Company or any of its Subsidiaries, (ii) commercially reasonable agreements not primarily relating to Taxes providing for the customary allocation or payment of personal property Taxes, sales or use Taxes or value added Taxes with respect to personal property leased, used, owned, purchased or sold in the ordinary course of business, and (iii) general and customary indemnification provisions not primarily relating to Taxes contained in the Company’s non-exclusive license agreements, in each case entered into in the ordinary course of business and consistent with past practices.

For the avoidance of doubt, this Section 6.17 shall not prohibit any such holder from selling Parent securities owned by such holder as of the date of this Agreement.

Section 6.18 Merger Consideration Allocation Schedule. No later than the earlier of (x) two (2) business days before the anticipated Closing Date and (y) three (3) business days from the date Parent informs the Company of the Parent Equity Offering Sale Price, the Company shall provide Parent with a certificate (the “Allocation Certificate”) signed by a duly authorized officer of the Company setting forth, for the Company Common Stock and each series of Company Preferred Stock, the calculation as of the Closing Date of the applicable Preferred Stock Merger Consideration Per Share, Preferred Stock Liquidation Preference and Common Stock Remaining Amount Per Share, in each case as of the Closing Date.

Section 6.19 Conversion of Bridge Loan Notes. The Company shall deliver to Parent copies of any Bridge Loan Notes issued after the date of this Agreement as soon as practicable after the date of such issuance (and in any event no later than two (2) business days after such issuance).

ARTICLE 9

SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS; INDEMNIFICATION

Section 9.1 Survival of Representations, Warranties and Covenants. The representations and warranties of the Company and Parent, as applicable, contained in this Agreement (whether or not contained in Article 3 or Article 4) or in any certificate delivered pursuant hereto shall survive the Closing until the date that is twelve (12) months after the Closing Date (the “Survival Period Termination Date”), other than the representations and warranties contained in Section 3.1, Section 3.2, Section 3.3, Section 3.16, Section 3.17, Section 3.21, Section 4.1, Section 4.2, Section 4.3, and Section 4.12 (“Fundamental Representations”), which shall survive (a) indefinitely or until the latest date permitted by applicable law, (b) and in the case of the representations and warranties contained in Section 3.16, until the date that is thirty (30) days after the expiration of the applicable statute of limitations; provided, however, that the claims specifically set forth in any claim for indemnity made by a Party hereto on or prior to the Survival Period Termination Date shall survive until such claim is finally resolved. All covenants set forth herein shall survive the Closing in accordance with their respective terms.

Section 9.2 General Indemnification.

(a) Subject to the other provisions of this Article 9, after the Closing, the Escrow Participating Holders shall indemnify, defend and hold Parent and/or its respective officers, directors, employees, Affiliates and/or agents (each a “Parent Indemnitee”) harmless from any damages, losses, liabilities, obligations, Taxes, claims of any kind, interest or expenses (including, without limitation, reasonable attorneys’ fees and expenses) (each a “Loss”) suffered or paid, directly or indirectly, as a result of, in connection with, or arising out of (i) any breach of any representation or warranty (A) contained in Article 3 (read without reference to materiality or Company Material Adverse Effect) or (B) in any certificate delivered by the Company to Parent pursuant to this Agreement and (ii) any breach by the Company of any of the covenants or agreements contained herein which are to be performed by the Company or its Subsidiaries on or before the Closing Date.

(b) Subject to the other provisions of this Article 9, after the Closing, Parent and the Surviving Corporation, jointly and severally, shall indemnify, defend and hold each of the Escrow Participating Holders and/or its respective officers, directors, employees, Affiliates and/or agents (each a “Holder Indemnitee”) harmless from any Losses suffered or paid, directly or indirectly, as a result of, in connection with, or arising out of (i) any breach of any representation or warranty (A) contained in Article 4 (read without reference to materiality or Parent Material Adverse Effect) or (B) in any certificate delivered by Parent to the Company pursuant to this Agreement and (ii) any breach by Parent or Merger Sub of any of the covenants or agreements contained herein which are to be performed by Parent or Merger Sub on or before the Closing Date.

-91-

(c) The obligations to indemnify and hold harmless pursuant to this Section 9.2 shall survive the consummation of the transactions contemplated hereby for the applicable period set forth in Section 9.1, except for claims for indemnification asserted prior to the end of such applicable period (which claims shall survive until final resolution thereof).

Section 9.3 Third Party Claims.

(a) If a claim, action, suit or proceeding by a Person who is not a Party or an Affiliate thereof (a “Third Party Claim”) is made against any Person entitled to indemnification pursuant to Section 9.2 (an “Indemnified Party”), and if such Person intends to seek indemnity with respect thereto under this Article 9, such Indemnified Party shall promptly give a Notice of Claim to the Party obligated to indemnify such Indemnified Party (such notified Party, the “Responsible Party”); provided that the failure to give such Notice of Claim shall not relieve the Responsible Party of its obligations hereunder, except to the extent that the Responsible Party is actually prejudiced thereby.

(i) If the Indemnified Party is Parent or a Subsidiary of Parent, then Parent shall have the right to assume the control of and conduct, through counsel reasonably acceptable to the Holder Representative and at the expense of Parent, the settlement or defense of such Third Party Claim; provided that Parent shall permit the Holder Representative to participate in such settlement or defense through counsel chosen by the Holder Representative (the fees and expenses of such counsel shall be borne by the Holders). Neither Parent nor any Subsidiary of Parent shall pay or settle any such claim without first seeking the prior written consent of the Holder Representative, which consent may be withheld in the Holder Representative’s sole discretion. Notwithstanding the foregoing provisions of this Section 9.3(a)(i), Parent or the applicable Subsidiary of Parent shall have the right to pay or settle any such claim; provided that in the event of such settlement, unless any consent from the Holder Representative contains an explicit agreement on behalf of the Escrow Participating Holders that the Escrow Participating Holders shall indemnify Parent or the applicable Subsidiary for such settlement amount, the Escrow Participating Holders and the Holder Representative shall not have waived any right to dispute any claim that may be made by a Parent Indemnitee for indemnification or reimbursement relating to such Third Party Claim either directly from the Escrow Participating Holders or from the Indemnity Escrow Account, as the case may be. Neither Parent nor any Subsidiary shall, except with the consent of the Holder Representative, enter into any settlement that does not include as an unconditional term thereof the giving by the Person(s) asserting such claim to all Parent Indemnitees and the Escrow Participating Holders of an unconditional release from all liability with respect to such claim or consent to entry of any judgment.

(ii) If the Indemnified Party is a Person other than Parent or a Subsidiary of Parent, the Responsible Party shall have thirty (30) days after receipt of such notice to assume the control of and conduct, through counsel reasonably acceptable to the Indemnified Party at the expense of the Responsible Party, of the settlement or defense thereof, and the Indemnified Party shall cooperate with the Responsible Party in connection therewith; provided that the Responsible Party shall permit the Indemnified Party to participate in such settlement or defense through counsel chosen by such Indemnified Party (the fees and expenses of such

-92-

counsel shall be borne by such Indemnified Party unless, in the opinion of counsel, representation of both the Responsible Party and the Indemnified Party by the same counsel would be inappropriate under applicable standards of professional care due to actual or potential differing interests between such parties, in which case the fees and expenses of counsel selected by the Indemnified Party shall be borne by the Responsible Party). So long as the Responsible Party is reasonably contesting any such claim in good faith, the Indemnified Party shall not pay or settle any such claim. Notwithstanding the foregoing provisions of this Section 9.3(a), the Indemnified Party shall have the right to pay or settle any such claim; provided that in such event it shall waive any right to indemnity or reimbursement therefor by the Responsible Party or from the Indemnity Escrow Account, as the case may be, for such claim unless the Responsible Party shall have consented to such payment or settlement (such consent not to be unreasonably withheld or delayed). If the Responsible Party does not notify the Indemnified Party within 30 days after the receipt of the Indemnified Party’s Notice of Claim hereunder that it elects to undertake the defense thereof, the Indemnified Party shall have the right to contest, settle or compromise the claim but shall not thereby waive any right to indemnity or reimbursement therefor pursuant to this Agreement. The Responsible Party shall not, except with the consent of the Indemnified Party (which consent shall not be unreasonably withheld or delayed), enter into any settlement that does not include as an unconditional term thereof the giving by the Person(s) asserting such claim to all Indemnified Parties of an unconditional release from all liability with respect to such claim or consent to entry of any judgment.

(b) The Responsible Party and the Indemnified Party shall reasonably cooperate in the defense or prosecution of any Third Party Claim in respect of which indemnity may be sought hereunder and each (or a duly authorized representative of such Party) shall furnish such records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials and appeals, as may be reasonably requested in connection therewith.

(c) The above provisions of this Section 9.3 shall not apply to any claim for indemnification for Taxes, the procedures with respect to which shall be governed by Section 6.16(a).

Section 9.4 Limitations on Indemnification Obligations. The rights of the Parent Indemnitees to indemnification pursuant to the provisions of Section 9.2(a) and of the Holder Indemnitees to indemnification pursuant to the provisions of Section 9.2(b) are subject to the following limitations:

(a) the amount of any and all Losses shall be determined net of any amounts recovered by the Parent Indemnitees or Holder Indemnitees, as applicable, under insurance policies or other collateral sources (such as contractual indemnities of any Person which are contained outside of this Agreement) with respect to such Losses;

(b) the Parent Indemnitees shall not be entitled to recover for any particular Loss pursuant to Section 9.2(a) unless such Loss equals or exceeds $50,000 (the “Parent De Minimis Amount”);

-93-

(c) the Parent Indemnitees shall not be entitled to recover Losses pursuant to Section 9.2(a)(i) until the total amount which the Parent Indemnitees would recover under Section 9.2(a)(i) (as limited by the provisions of Section 9.4(a), Section 9.4(b) and Section 11.11), but for this Section 9.4(c), exceeds $4,000,000 (the “Parent Threshold”), in which case, the Parent Indemnitees shall only be entitled to recover Losses in excess of such amount;

(d) from and after the Closing, the shares in the Indemnity Escrow Account, at any given time, shall be the sole source of recovery with respect to Losses indemnifiable pursuant to Section 9.2(a) and in no event shall the Parent Indemnitees be entitled to recover more than the amount of the Parent Common Stock and funds in the Indemnity Escrow Account pursuant to Section 9.2(a); provided, however, that this Section 9.4(d) shall not apply to Losses suffered or paid, directly or indirectly, by a Parent Indemnitee as a result of, in connection with, or arising out of any breach of any Fundamental Representation (“Parent Excess Indemnification Losses”) for which the Parent Indemnitees shall only be entitled to recover the value of the Stock Consideration, such value determined based on the Twenty Day Average for the date of final resolution of such claim. Each Company stockholder receiving Merger Consideration Shares in the Merger shall be liable Severally in Proportion, and not jointly, for Parent Excess Indemnification Losses; provided, that no Company stockholders shall be liable for amounts in excess of the Merger Consideration Shares received by such Company stockholder; provided, further, that the Parent Indemnitees shall first make a claim for Losses against the Indemnity Escrow Account and the Indemnity Escrow Account shall be exhausted before any claims for Losses are made directly against the Company stockholders. “Severally in Proportion” means several liability for a percentage of the Parent Excess Indemnification Losses, if any, equal to such stockholder’s Escrow Percentage;

(e) the Holder Indemnitees shall not be entitled to recover Losses pursuant to Section 9.2(b) unless such Loss equals or exceeds $50,000 (the “Holder De Minimis Amount”);

(f) the Holder Indemnitees shall not be entitled to recover Losses pursuant to Section 9.2(b)(i) until the total amount which the Holder Indemnitees would recover under Section 9.2(b)(i) (as limited by the provisions of Section 9.4(a), Section 9.4(e) and Section 11.11), but for this Section 9.4(f), exceeds $4,000,000 (the “Holder Threshold”), in which case, the Holder Indemnitees shall only be entitled to recover Losses in excess of such amount; and

(g) from and after the Closing, (i) the Parent Indemnity Shares, at any given time, and Parent Additional Indemnity Shares, at any given time, shall be the sole source of recovery with respect to Losses indemnifiable pursuant to Section 9.2(b) and (ii) in no event shall the Holder Indemnitees be entitled to recover more than the number of shares of Parent Common Stock equal to the number of Escrow Shares pursuant to Section 9.2(b); provided, however, that the Holder Indemnitees will not be entitled to any further recovery for Losses indemnifiable pursuant to Section 9.2(b) to the extent that either (x) the number of Parent Indemnity Shares and Parent Additional Indemnity Shares that the Company has issued or is obligated to issue plus the number of shares of Parent Common Stock that Parent has issued or becomes obligated to issue to satisfy its indemnification obligations pursuant to Section 3.01(d) of the Investor Financing Agreement (y) equals or exceeds the Escrow Shares; provided however, that clause (ii) of this Section 9.4(g) shall not apply to Losses suffered or paid, directly or indirectly, by the Holder Indemnitees as a result of, in connection with, or arising out of any breach of any Fundamental Representation or breach of covenant.

-94-

Section 9.5 Exclusive Remedy; Reliance on Representations. Notwithstanding anything contained herein to the contrary but subject to Section 11.13, from and after the Closing Date, indemnification pursuant to the provisions of this Article 9 shall be the exclusive remedy for Parent and the Escrow Participating Holders for any misrepresentation or breach of any warranty, covenant or other provision contained in this Agreement or in any certificate delivered pursuant hereto, other than in the case of fraud or knowing misrepresentation solely with respect to the party committing such fraud or misrepresentation. Except for the representations and warranties set forth in Article 4 of the Agreement, the Company and the Escrow Participating Holders expressly disclaim any reliance on any representations or warranties of any kind or nature, express or implied, including, in the due diligence materials, or in any presentation of the business of the Parent by management of the Parent or others in connection with the transactions contemplated hereby and none of the Holder Indemnified Parties shall be entitled to make a claim for Losses related thereto. Except for the representations and warranties set forth in Article 3 of the Agreement, the Parent expressly disclaims any reliance on any representations or warranties of any kind or nature, express or implied, including, in the due diligence materials, or in any presentation of the business of the Company by management of the Company or others in connection with the transactions contemplated hereby and none of the Parent Indemnified Parties shall be entitled to make a claim for Losses related thereto.

Section 9.6 Tax Treatment. All indemnification payments pursuant to this Article 9 (including any share of Parent Common Stock released from the Indemnity Escrow Account to Parent) shall be treated for all Tax purposes as adjustments to the Closing Merger Consideration, except to the extent otherwise required pursuant to a “determination” within the meaning of Section 1313(a) of the Code (or any corresponding or similar provision of state, local or foreign Law).

ARTICLE 10

HOLDER REPRESENTATIVE

Section 10.1 Holder Representative.

(a) The Holder Representative is authorized and empowered to act as a representative for the benefit of and on behalf of the Escrow Participating Holders as the exclusive agent and attorney-in-fact with the power and authority to act on behalf of the Escrow Participating Holders in connection with, and to facilitate the consummation of, the transactions contemplated hereby, including pursuant to the Ancillary Agreements, which shall include the power and authority:

(i) to execute and deliver the Ancillary Agreements to which the Holder Representative is a party (with such modifications or changes therein to which the Holder Representative, in its sole discretion, shall have consented, the “Holder Agreements”) and to agree to such amendments or modifications thereto as the Holder Representative, in its sole discretion, determines to be desirable;

-95-

(ii) to execute and deliver such waivers and consents in connection with this Agreement and the Holder Agreements and the consummation of the transactions contemplated hereby and thereby as the Holder Representative, in its sole discretion, may deem necessary or desirable;

(iii) as Holder Representative, to enforce and protect the rights and interests of the Escrow Participating Holders and to enforce and protect the rights and interests of the Escrow Participating Holders arising out of or under or in any manner relating to this Agreement and the Holder Agreements, and each other agreement, document, instrument or certificate referred to herein or therein or the transactions provided for herein or therein (including in connection with any and all claims for indemnification brought under Article 9), and to take any and all actions which the Holder Representative believes are necessary or appropriate under the Holder Agreements and/or this Agreement for and on behalf of the Escrow Participating Holders, including asserting or pursuing any claim, action, proceeding or investigation (a “Claim”) against Parent, Merger Sub and/or the Surviving Corporation, defending any Third Party Claims or Claims by the Parent Indemnitees, consenting to, compromising or settling any such Claims, conducting negotiations with Parent, the Surviving Corporation and their respective representatives regarding such Claims, and, in connection therewith, to (A) assert any claim or institute any action, proceeding or investigation; (B) investigate, defend, contest or litigate any claim, action, proceeding or investigation initiated by Parent, the Surviving Corporation or any other Person against the Holder Representative and/or any of the Escrow Participating Holders or the Escrow Shares, and receive process on behalf of any or all Escrow Participating Holders in any such claim, action, proceeding or investigation and compromise or settle on such terms as the Holder Representative shall determine to be appropriate, and give receipts, releases and discharges with respect to, any such claim, action, proceeding or investigation; (C) file any proofs of debt, claims and petitions as the Holder Representative may deem advisable or necessary; (D) settle or compromise any claims asserted under the Holder Agreements; and (E) file and prosecute appeals from any decision, judgment or award rendered in any such action, proceeding or investigation, it being understood that the Holder Representative shall not have any obligation to take any such actions, and shall not have any liability for any failure to take any such actions;

(iv) to refrain from enforcing any right of the Escrow Participating Holders or any of them and/or the Holder Representative arising out of or under or in any manner relating to this Agreement, the Holder Agreements or any other agreement, instrument or document in connection with the foregoing; provided, however, that no such failure to act on the part of the Holder Representative, except as otherwise provided in this Agreement or in the Holder Agreements, shall be deemed a waiver of any such right or interest by the Holder Representative or by the Escrow Participating Holders unless such waiver is in writing signed by the waiving party or by the Holder Representative; and

-96-

(v) to make, execute, acknowledge and deliver all such other agreements, guarantees, orders, receipts, endorsements, notices, requests, instructions, certificates, stock powers, letters and other writings, and, in general, to do any and all things and to take any and all action that the Holder Representative, in its sole and absolute discretion, may consider necessary or proper or convenient in connection with or to carry out the transactions contemplated by this Agreement, the Holder Agreements, and all other agreements, documents or instruments referred to herein or therein or executed in connection herewith and therewith.

(b) In connection with the foregoing, at the Closing, the Surviving Corporation shall transfer an amount of cash set forth on Schedule 10.1 to the Holder Representative (the “Expense Funds”), to be used by the Holder Representative to pay fees and expenses incurred by the Holder Representative in its capacity as Holder Representative. The Escrow Participating Holders will not receive any interest or earnings on the Expense Funds and irrevocably transfer and assign to the Holder Representative any ownership rights that they may otherwise have had in any such interest or earnings. The Holder Representative will not be liable for any loss of principal of the Expense Funds other than as a result of its gross negligence or willful misconduct. For tax purposes, the Expense Funds will be treated as having been received and voluntarily set aside by the Escrow Participating Holders at the time of Closing. Once the Holder Representative determines, in its sole discretion, that the Holder Representative does not expect to incur any additional expenses in its capacity as the Holder Representative, the Holder Representative will deliver to the Escrow Agent the remaining unused Expense Funds, if any, to appropriately distribute such funds to the Escrow Participating Holders in connection with the final release of the Escrow Shares. In connection with this Agreement, the Holder Agreements and any instrument, agreement or document relating hereto or thereto, and in exercising or failing to exercise all or any of the powers conferred upon the Holder Representative hereunder (i) the Holder Representative shall incur no responsibility or liability whatsoever to any Escrow Participating Holder by reason of any error in judgment or other act or omission performed or omitted hereunder or in connection with the Holder Agreements or any such other agreement, instrument or document, excepting only responsibility for any act or failure to act which represents willful misconduct, and (ii) the Holder Representative shall be entitled to rely on the advice of counsel, public accountants or other independent experts experienced in the matter at issue, and any error in judgment or other act or omission of the Holder Representative pursuant to such advice shall in no event subject the Holder Representative to liability to any Escrow Participating Holders. Each Escrow Participating Holder shall indemnify, pro rata based upon such Escrow Participating Holder’s Escrow Percentage, and hold harmless the Holder Representative against all losses, damages, liabilities, claims, obligations, costs and expenses, including reasonable attorneys’, accountants’ and other experts’ fees and the amount of any judgment against them, of any nature whatsoever (including, but not limited to, any and all expense whatsoever reasonably incurred in investigating, preparing or defending against any litigation, commenced or threatened or any claims whatsoever), (collectively, “Representative Losses”), arising out of or in connection with the Holder Representative’s execution and performance of this Agreement and the Holder Agreements, including any claim, investigation, challenge, action or proceeding or in connection with any appeal thereof, relating to the acts or omissions of the Holder Representative hereunder, or under the Holder Agreements or otherwise, in each case as such Representative Loss is suffered or incurred. In the event of any action or proceeding which finally adjudicates that any such Representative Loss has been primarily caused by the willful misconduct of the Holder Representative, the Holder Representative will reimburse the Escrow

-97-

Participating Holders the amount of such indemnified Representative Loss attributable to such willful misconduct. In the event of any indemnification hereunder, upon written notice from the Holder Representative to the Escrow Participating Holders as to the existence of a deficiency toward the payment of any such indemnification amount, each Escrow Participating Holder shall promptly deliver to the Holder Representative full payment of his or her ratable share of the amount of such deficiency based upon such Escrow Participating Holder’s Escrow Percentage. If not paid directly to the Holder Representative by the Escrow Participating Holders, any such Representative Losses may be recovered by the Holder Representative from the Expense Funds or the Escrow Shares at such time as remaining Escrow Shares would otherwise be distributable to the Escrow Participating Holders; provided, that while this section allows the Holder Representative to be paid from the Expense Funds and the Escrow Shares, this does not relieve the Escrow Participating Holders from their obligation to promptly pay such Representative Losses as they are suffered or incurred, nor does it prevent the Holder Representative from seeking any remedies available to it at law or otherwise. Neither Parent, Merger Sub nor, from and after the Closing, the Company shall have any obligation or liability to the Holder Representative, and the Holder Representative shall not look to Parent, Merger Sub or, from and after the Closing, the Company, with respect to any Representative Losses, except to the extent of the Expense Funds to be paid or funded by the Company or the Surviving Corporation in an amount not to exceed the amount set forth on Schedule 10.1.

(c) All of the indemnities, immunities and powers granted to the Holder Representative under this Agreement shall survive the Effective Date and/or any termination of this Agreement and/or the Holder Agreements.

(d) If the Holder Representative shall have resigned, died or otherwise become incapacitated or been removed, Escrow Participating Holders who in the aggregate hold at least a majority of the interest in the Indemnity Escrow Account shall appoint, subject to the prior approval of the Parent (such approval not to be unreasonably withheld), a successor holder representative not later than thirty (30) days following the resignation, death, incapacity or removal of the Holder Representative.

(e) Parent and the Surviving Corporation shall have the right to rely upon all actions taken or omitted to be taken by the Holder Representative pursuant to this Agreement and the Holder Agreements, all of which actions or omissions shall be legally binding upon the Escrow Participating Holders.

(f) The grant of authority provided for herein (i) is coupled with an interest and shall be irrevocable and shall survive the death, incompetency, bankruptcy or liquidation of any holder of Company Common Stock, Company Preferred Stock or Company Options; and (ii) shall survive the consummation of the Merger.

Section 11.3 Governing Law. This Agreement shall be governed by and construed in accordance with the Laws of the State of Delaware, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Law of any jurisdiction other than the State of Delaware.

Section 11.5 Construction; Interpretation.

No Party, nor its respective counsel, shall be deemed the drafter of this Agreement for purposes of construing the provisions hereof, and all provisions of this Agreement shall be construed according to their fair meaning and not strictly for or against any Party. Unless otherwise indicated to the contrary herein by the context or use thereof: (a) the words, “herein,” “hereto,” “hereof” and words of similar import refer to this Agreement as a whole, including, without limitation, the Schedules and exhibits, and not to any particular section, subsection, paragraph, subparagraph or clause contained in this Agreement, (b) masculine gender shall also include the feminine and neutral genders, and vice versa; and (c) words importing the singular shall also include the plural, and vice versa.

Section 11.6 Exhibits and Schedules. All Exhibits and Schedules, or documents expressly incorporated into this Agreement, are hereby incorporated into this Agreement and are hereby made a part hereof as if set out in full in this Agreement. Any item disclosed in any Schedule referenced by a particular section in this Agreement shall be deemed to have been disclosed with respect to every other section in this Agreement if the relevance of such disclosure to such other sections is reasonably apparent. The specification of any dollar or euro amount in the representations or warranties contained in this Agreement or the inclusion of any specific item in any Schedule is not intended to imply that such amounts, or higher or lower amounts or the items so included or other items, are or are not material, and no Party shall use the fact of the setting of such amounts or the inclusion of any such item in any dispute or controversy as to whether any obligation, items or matter not described herein or included in a Schedule is or is not material for purposes of this Agreement.

This Agreement shall be binding upon and inure solely to the benefit of each Party and its successors and permitted assigns and, except as provided in this Article 11, nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any rights, benefits or remedies of any nature whatsoever under or by reason of this Agreement; except as set forth in Section 6.11 with respect to the Covered Persons and Article 9 with respect to the Parent Indemnified Parties and Holder Indemnified Parties.

Section 11.11 Waiver of Jury Trial. Each Party hereby waives, to the fullest extent permitted by Law, any right to trial by jury of any claim, demand, action, or cause of action (a) arising under this Agreement or (b) in any way connected with or related or incidental to the dealings of the Parties in respect of this Agreement or any of the transactions related hereto, in each case, whether now existing or hereafter arising, and whether in contract, tort, equity, or otherwise. Each Party hereby further agrees and consents that any such claim, demand, action, or cause of action shall be decided by court trial without a jury and that the Parties may file a copy of this Agreement with any court as written evidence of the consent of the Parties to the waiver of their right to trial by jury.

Section 11.12 Jurisdiction and Venue. Each Party hereby irrevocably submits to the jurisdiction of the Delaware Court of Chancery or in the event (but only in the event) that such court does not have subject matter jurisdiction over such action or proceeding, in the United States District Court for the District of Delaware in respect of the interpretation and enforcement of the provisions of this Agreement and of the documents referred to in this Agreement, and in respect of the transactions contemplated hereby, and hereby waives, and agrees not to assert, as a defense in any action, suit or proceeding for the interpretation or enforcement hereof or of any such document, that it is not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in the Delaware Court of Chancery, or in the event (but only in the event) that such court does not have subject matter jurisdiction over such action or proceeding, in the United States District Court for the District of Delaware, or that this Agreement or any such document may not be enforced in or by such courts, and the parties hereto irrevocably agree that all claims

-102-

with respect to such action or proceeding shall be heard and determined in the Delaware Court of Chancery, or in the event (but only in the event) that such court does not have subject matter jurisdiction over such action or proceeding, in the United States District Court for the District of Delaware. The parties hereby consent to and grant the Delaware Court of Chancery, or in the event (but only in the event) that such court does not have subject matter jurisdiction over such action or proceeding, the United States District Court for the District of Delaware, jurisdiction over the person of such parties and, to the extent permitted by Law, over the subject matter of such dispute and agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 11.2 or in such other manner as may be permitted by Law shall be valid and sufficient service thereof.

Section 11.13 Remedies; Limitation on Damages.

(a) Any Person having any rights under any provision of this Agreement shall be entitled to enforce such rights specifically (without posting a bond or other security). All such rights and remedies shall be cumulative and non-exclusive, and may be exercised singularly or concurrently. The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached.

(b) Each Party agrees that, in the event of any breach or threatened breach by any other Party of any covenant or obligation contained in this Agreement, the non-breaching Party shall be entitled to seek and obtain (i) a decree or order of specific performance to enforce the observance and performance of such covenant or obligation, and (ii) an injunction restraining such breach or threatened breach. In circumstances where Parent or the Company is obligated to consummate the transactions contemplated by this Agreement and such transactions have not been consummated (other than as a result of the other party’s refusal to close in violation of this Agreement) each of Parent and the Company expressly acknowledges and agrees that the other party and its shareholders shall have suffered irreparable harm, that monetary damages will be inadequate to compensate such other party and its shareholders, and that such other party on behalf of itself and its shareholders shall be entitled to enforce specifically Parent’s or the Company’s, as the case may be, obligation to consummate such transactions.

(c) Each party further agrees that no other party or any other Person shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 11.13, and each party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

(d) Anything to the contrary notwithstanding, no Party shall be liable for any consequential damages, including, without limitation, loss of revenue, income or profits, loss in value of assets or securities, punitive, special or indirect damages, relating to any breach of this Agreement; provided, that the above provisions of this Section 11.13(d) shall not prevent Parent Indemnitees from recovering “interest, penalties and additions to tax” described in the definition of “Tax” in Section 1.1.

-103-

Section 11.14 Waiver of Conflicts Regarding Representation. If the Holder Representative so desires, acting on behalf of the Escrow Participating Holders and without the need for any consent or waiver by the Company or Parent, Cooley shall be permitted to represent the Holder Representative and/or the Escrow Participating Holders after the Closing in connection with any matter, including anything related to the transactions contemplated by this Agreement, any other agreements referenced herein or any disagreement or dispute relating thereto. Without limiting the generality of the foregoing, after the Closing, Cooley shall be permitted to represent the Holder Representative and/or the Escrow Participating Holders any of their agents and affiliates, or any one or more of them, in connection with any negotiation, transaction or dispute (including any litigation, arbitration or other adversary proceeding) with Parent, the Company or any of their agents or affiliates under or relating to this Agreement, any transaction contemplated by this Agreement, and any related matter, such as claims or disputes arising under other agreements entered into in connection with this Agreement, including with respect to any indemnification claims. Upon and after the Closing, the Company shall cease to have any attorney-client relationship with Cooley, unless and to the extent Cooley is specifically engaged in writing by the Company to represent the Company after the Closing and either such engagement involves no conflict of interest with respect to Holder Representative and/or the Escrow Participating Holders or the Holder Representative consents in writing at the time to such engagement. Any such representation of the Company by Cooley after the Closing shall not affect the foregoing provisions hereof.
