If there is a vacancy at any time in the position of Securityholders Representative (including if Denham Commodity Partners Fund LP, or an Affiliate thereof, declines to serve as Securityholders Representative pursuant to the foregoing sentence within ten (10) days following the resignation of Mx SR LLC as Securityholders Representative), the Person last serving as Securityholders Representative shall request from the Paying Agent a list of all Securityholders and the addresses on file with the Paying Agent for such Securityholders and shall deliver, within seven (7) Business Days of such Person’s receipt of such addresses, a notice to each such Securityholder at such address notifying the Securityholders (i) that a vacancy in the position of Securityholders Representative exists and (ii) to the extent any Securityholders have agreed to be appointed Securityholders Representative, of the names of such Securityholders. Following the delivery of such notice, the vacancy shall be filled by a vote of the Securityholders in accordance with Section 2.4(b). If at any time there is no Person acting as the Securityholders Representative and the Securityholders fail to fill such vacancy within thirty (30) days following the resignation of the then current Securityholders Representative, Parent may appoint (with the consent of the Securityholder to be appointed the Securityholders Representative) the Securityholders Representative from among the Securityholders; provided, however, that the Securityholders Representative shall not be a trust; and provided further, that the Percentage Share of the Securityholders Representative selected by Parent must be greater than one percent as of the Closing Date. In the event that Parent appoints a Securityholders Representative pursuant to the foregoing sentence (and such Securityholder agrees to such appointment), the Securityholders may revoke such appointment and appoint a replacement Securityholders Representative at any time in accordance with Section 2.4(b). In no event shall any Securityholder be obligated to accept an appointment by Parent to serve as Securityholders Representative.

(e) The Securityholders Representative acknowledges that it has carefully read and understands this Agreement and hereby accepts the appointment and designation made hereunder.

(f) The Securityholders Representative shall act for the Securityholders on all of the matters set forth herein in the manner the Securityholders Representative reasonably believes to be in the best interests of the Securityholders as a group and consistent with the obligations of the Securityholders Representative and the Securityholders under this Agreement. Notwithstanding the foregoing, the Securityholders Representative shall not be liable to Parent, Merger Sub, the Surviving Corporation or the Securityholders in its capacity as Securityholders Representative for any error of judgment, or any act done or step taken or omitted by it in good faith or for any mistake in fact or Law, or for anything that it may do or refrain from doing in connection with this Agreement, except for its own gross negligence or willful misconduct. The Securityholders Representative shall not have any duties or responsibilities other than those expressly set forth in this Agreement, the Escrow Agreement or the Securityholders Representative Escrow Agreement, and no implied covenants, functions, responsibilities, duties or liabilities shall be read into this Agreement or shall otherwise exist against the Securityholders Representative. The Securityholders Representative shall be entitled to rely, and shall be fully protected in

relying, upon any statements furnished to it by the Company, the Surviving Corporation, any Securityholder, Parent or Merger Sub, or any other evidence deemed by the Securityholders Representative to be reliable. The Securityholders Representative may seek the advice of legal counsel in the event of any dispute or question as to the construction of any of the provisions of this Agreement or any other Transaction Document or its duties hereunder or thereunder, and it shall incur no liability in its capacity as Securityholders Representative to Parent, the Surviving Corporation or any Securityholder and shall be fully protected with respect to any action taken, omitted or suffered by it in accordance with the advice of such counsel. The Securityholders shall severally, based on each Securityholder’s Percentage Share of the applicable liabilities, claims, actions, damages, losses and expenses, indemnify and hold harmless and defend the Securityholders Representative, its Affiliates and its Representatives against any and all liabilities, claims, actions, damages, losses and expenses (including legal and other professional fees and expenses and litigation costs) arising out of or in connection with (i) the Securityholders Representative’s acts or omissions to act, resulting from, arising out of, incurred in connection with, or otherwise with respect to, this Agreement, the Escrow Agreement and the Securityholders Representative Escrow Agreement and (ii) actions or omissions otherwise reasonably believed to be in the scope of the Securityholders Representative’s authority; provided that, in each case, such actions or omissions did not constitute gross negligence or willful misconduct.

(g) The Securityholders shall pay the Securityholders Representative an annual fee of $100,000 through the date on which all of the funds in the Fixed Escrow Account are finally disbursed in accordance with the terms of this Agreement and the Escrow Agreement for each year or any portion of a year it serves as Securityholders Representative, which such fee shall be deducted from the escrow account established pursuant to the terms of the Securityholders Representative Escrow Agreement for compensation and reimbursement of the Securityholders Representative (the “Securityholders Representative Escrow Account”) and shall be paid in advance on the Closing Date and on each anniversary of the Closing Date. In addition to such annual fee, the Securityholders shall reimburse the Securityholders Representative for any and all costs, expenses and other liabilities incurred by the Securityholders Representative in connection with the performance of its duties under this Agreement and such costs and expenses shall be paid as a Transaction Cost if incurred and ascertainable prior to Closing, and, thereafter, in accordance with this Section 2.4(g). The Securityholders Representative shall be entitled to deduct any amounts from the Securityholders Representative Escrow Account necessary to satisfy the indemnification and payment obligations of the Securityholders pursuant to Sections 2.4(f)-(g). If at any time there are insufficient (or no) funds remaining in the Securityholders Representative Escrow Account to pay such amounts, (A) the Securityholders Representative may deduct any amount owing to it pursuant to Sections 2.4(f)-(g), or any amounts it reasonably believes may be payable to it in the future, from any amounts that have been finally determined to be distributable to the Securityholders from the Fixed Escrow Account or the Adjustment Escrow Account in accordance with the terms of the Escrow Agreement and this Agreement, and (B) if no such amounts are to be distributed to the Securityholders, or if such amounts are insufficient, the Securityholders shall reimburse the Securityholders Representative based on each Securityholder’s Percentage Share of such amounts owing

to the Securityholders Representative. The Securityholders Representative shall have the right to deliver instructions to the Escrow Agent at any time to disburse funds to the Securityholders Representative from the Securityholders Representative Escrow Account or to withhold amounts that have been finally determined to be distributable to the Securityholders from the Fixed Escrow Account or the Adjustment Escrow Account in accordance with the terms of the Escrow Agreement and this Agreement, without the necessity of obtaining approval from any other Person (including any Securityholder); provided that such instructions comply with this Section 2.4(g).

(h) Notwithstanding anything to the contrary in this Agreement:

(i) with respect to any provision of this Agreement that requires Parent or the Surviving Corporation to obtain the consent or approval of the Securityholders Representative after the Closing Date, if the Securityholders Representative fails to provide written notice of the Securityholders Representative’s consent or rejection within the later of (x) the time period provided for in the applicable provisions of this Agreement and (y) fifteen (15) Business Days after the date Parent or the Surviving Corporation, as applicable, requested such consent or approval, then the Securityholders Representative shall be deemed to have rejected the request; and

(ii) if at anytime the Securityholders Representative shall have resigned and no replacement Securityholders Representative shall have been designated in accordance with the terms of this Agreement (after the expiration of the applicable time periods set forth in Section 2.4(d), regardless of whether or not the Securityholders Representative has complied with, or taken the actions required by, Section 2.4(d)):

(A) any requirement in this Agreement to deliver notice to the Securityholders Representative shall be deemed to be satisfied upon providing notice, in accordance with Section 13.5, to each of the Securityholders at the applicable addresses on file with the Paying Agent; and

(B) Parent or the Surviving Corporation, as applicable, may take any action that is to be taken by the Securityholders Representative or that requires the consent or approval of the Securityholders Representative pursuant to this Agreement if (1) Parent or the Surviving Corporation, as applicable, delivers written notice of its intention to take such action to each of the Securityholders at the applicable addresses on file with the Paying Agent and (2) within fifteen (15) Business Days after the date of the mailing of such written notice, Parent or the Surviving Corporation, as applicable, does not receive written notice from a

replacement Securityholders Representative appointed in accordance with the terms of this Agreement objecting to Parent or the Surviving Corporation, as applicable, taking such action; provided, that, if Parent’s or the Surviving Corporation’s inability to take the applicable action prior to the delivery of notice to the Securityholders or the expiration of such fifteen-Business Day period would materially prejudice the rights of Parent or the Surviving Corporation, then Parent or the Surviving Corporation, as applicable, may, in good faith, take such action and thereafter shall deliver prompt written notice thereof to the Securityholders.

(e) to the Company or the Surviving Corporation, for the benefit of the RSU Holders, an amount equal to the Closing Common Share Price multiplied by the number of shares of Common Stock subject to Company Restricted Share Units outstanding immediately prior to the Effective Time.

5.4 Mechanics of Payments.

(a) Prior to the Effective Time, Parent shall enter into an agreement with Manufacturers and Traders Trust Company, or such other Person reasonably acceptable to the Company and Parent, in the form attached hereto as Exhibit F (or in such other form as may be reasonably acceptable to both the Company and Parent) (the “Paying Agent Agreement”), to act as paying agent for the Securityholders in connection with the Merger (the “Paying Agent”) and to receive (i) for the benefit of the Stockholders, the Merger Consideration and (ii) for the benefit of the Securityholders, any amounts payable to the Securityholders upon release of funds pursuant to the Escrow Agreement and the Securityholders Representative Escrow Agreement. Parent shall deposit, or shall cause to be deposited, an amount equal to the Merger Consideration with the Paying Agent at or prior to the Effective Time. The Merger Consideration deposited with the Paying Agent shall, pending its disbursement to the Stockholders, be invested by the Paying Agent as provided in the Paying Agent Agreement. Any amounts in excess of the Merger Consideration, including any interest or other income resulting from such investments, shall be paid to Parent or Merger Sub upon termination of the paying agency arrangements under the Paying Agent Agreement and shall be the property of Parent or Merger Sub. Notwithstanding anything to the contrary, Parent shall promptly replace funds deposited with the Paying Agent (by Parent or the Escrow Agent) in the event of any loss of such funds as a result of the investment of such funds. Subject to the last sentence of this Section 5.4(a) and the immediately preceding sentence, Parent shall be deemed for all purposes of this Agreement to have satisfied its obligation to pay the Merger Consideration to the Stockholders hereunder at the Closing upon the Paying Agent’s receipt of the Merger Consideration, it being expressly agreed that Parent’s payment of the Merger Consideration to the Paying Agent shall forever and irrevocably be deemed to constitute payment to each and every Stockholder (other than with respect to Dissenting Shares) the full amount of the portion of the Merger Consideration which is owed to such Stockholder under this Agreement at the Closing. In the event the Merger Consideration is paid to the Paying Agent and the Paying Agent fails to pay the full amount of the portion of the Merger Consideration which is owed to any Stockholder under this Agreement, such Stockholder’s sole and exclusive remedy shall be the right to

be subrogated to Parent’s rights under the Paying Agent Agreement. Notwithstanding the deposit of the Merger Consideration with the Paying Agent, Parent shall continue to have the obligation to pay the remaining portion of the Common Share Price, if any, due and owing to the Securityholders hereunder, which obligation shall be deemed to have been satisfied by the deposit by Parent of the Fixed Escrow Amount, the Securityholders Representative Escrow Amount and the Adjustment Escrow Amount with the Escrow Agent on or prior to the Closing Date (subject to the obligations set forth in the fifth sentence of this Section 5.4(a)) and Parent’s compliance with the terms and conditions of the Escrow Agreement and this Agreement with respect to distributions of any portions of the Fixed Escrow Amount and the Adjustment Escrow Amount, if any, to the Paying Agent thereunder, it being expressly agreed that (subject to the obligations set forth in the fifth sentence of this Section 5.4(a)) Parent’s deposit of the Fixed Escrow Amount, the Securityholders Representative Escrow Amount and the Adjustment Escrow Amount with the Escrow Agent on or prior to the Closing Date and Parent’s and the Surviving Corporation’s compliance with the terms and conditions of the Escrow Agreement and this Agreement with respect to distributions of the Fixed Escrow Amount and the Adjustment Escrow Amount, if any, to the Paying Agent, and Parent’s and the Surviving Corporation’s compliance with the Paying Agent Agreement, shall forever and irrevocably be deemed to constitute payment to each and every Securityholder (other than with respect to Dissenting Shares) of the full amount of the remaining portion of the Common Share Price, if any, that is owed to the Securityholders hereunder.

(b) As soon as reasonably practicable after the Effective Time and in any event not later than two (2) Business Days following the Closing Date, the Paying Agent shall mail to each Stockholder of record as of the Effective Time whose shares of Common Stock were converted into the right to receive the Common Share Price pursuant to Section 4.1, a letter of transmittal in the form attached hereto as Exhibit G (or such other form as may be reasonably acceptable to each of the Company, Parent and the Paying Agent) (a “Letter of Transmittal”), which shall include instructions for effecting the surrender of the certificates which immediately prior to the Effective Time represented outstanding Common Stock (including Restricted Shares) (the “Certificates”), in exchange for payment of the portion of the Merger Consideration to which each Stockholder may be entitled, and shall specify that delivery shall be effected, and risk of loss shall pass, only upon proper delivery to the Paying Agent of the Certificates (provided, that the Company shall deliver any Certificates representing Restricted Shares held by the Company on behalf of the applicable Restricted Holder to such Restricted Holder prior to the Effective Time, or at such Restricted Holder’s direction, to the Paying Agent). Prior to the Effective Time, the Company shall provide to each RSU Holder whose Company Restricted Share Units were converted into the right to receive the Common Share Price pursuant to Section 4.1, a Company Restricted Share Unit surrender agreement in the form attached hereto as Exhibit H (or in such other form as may be reasonably acceptable to each of the Company, Parent and the Paying Agent) (a “Surrender Agreement”), which shall contain an acknowledgement of surrender and such other terms as Parent may reasonably specify. Upon delivery of a duly completed and validly executed Surrender Agreement to the Company and Parent, the applicable RSU Holder executing such Surrender Agreement shall be entitled to receive the Closing Common Share Price (less the applicable Tax withholdings pursuant

to Section 4.1(d)), at the Closing in exchange for such RSU Holders’ Company Restricted Share Units and such Company Restricted Share Units shall forthwith be cancelled. Upon delivery of a Surrender Agreement to the Paying Agent, the applicable RSU Holder executing such Surrender Agreement shall be entitled to receive any remaining portion of the Common Share Price (less applicable federal, state and local income Tax withholding and Social Security, Medicare, state disability, unemployment and other withholding obligations) in respect of the Company Restricted Share Units held by such RSU Holder immediately prior to the Effective Time as may become payable pursuant to the terms of this Agreement. Upon surrender of a Certificate for cancellation to the Paying Agent, together with a Letter of Transmittal, duly completed and validly executed in accordance with the instructions, the holder of such Certificate shall be entitled to receive in exchange therefor the amounts set forth in Section 4.1 and the Certificates so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any amount payable upon due surrender of the Certificates or Company Restricted Share Units. If payment is to be made to a Person other than the Person in whose name a surrendered Certificate is registered, it shall be a condition of payment that (x) the Certificate so surrendered shall be accompanied by all documents required to evidence and effect that transfer and (y) the Paying Agent shall be entitled to deduct any applicable Taxes from the payments made to such Person, unless the Person requesting such payment shall have established to the reasonable satisfaction of the Surviving Corporation that such Tax either has been paid or is not applicable. Each Certificate and each Company Restricted Share Unit shall be deemed at any time after the Effective Time to represent only the right to receive, upon surrender in accordance with this Section 5.4, the payments set forth in Section 4.1. No interest shall be paid or accrued on any cash payable to Securityholders pursuant to the provisions of this Article V, except as expressly set forth in this Agreement.

(c) If 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 the posting by such Person of a bond pursuant to and in accordance with the Letter of Transmittal, as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent shall pay the applicable portion of the Merger Consideration to be paid in respect of the Common Stock formerly represented by such lost, stolen or destroyed Certificate.

(d) From and after the Effective Time, the Securityholders shall cease to have any rights with respect to the Common Stock or Company Restricted Share Units, except as otherwise provided herein or by applicable Law.

(e) At any time following the termination of the Escrow Agreement in accordance with the terms thereof, Parent or the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any funds (including any interest earned thereon) that had been made available to the Paying Agent for disbursement to Securityholders who have not, prior to such date, surrendered their Company Restricted Share Units or Certificates as required by the Letter of Transmittal, and thereafter such Securityholders shall be entitled to look only to Parent and the Surviving Corporation (subject to abandoned property, escheat or other similar Laws) as general creditors

thereof with respect to any amounts that may be payable to such Securityholders, as determined pursuant to this Agreement, without any interest thereon. Anything herein to the contrary notwithstanding, none of the Company, Parent, Merger Sub, the Surviving Corporation, the Paying Agent or any other Person shall be liable to any Securityholder for any amount properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(f) Parent or the Surviving Corporation shall be entitled to deduct and withhold, or to direct the Paying Agent to deduct and withhold, from any amount payable pursuant to this Agreement such amounts as Parent or the Surviving Corporation shall determine in good faith it is required to deduct and withhold with respect to the making of such payment under the Code or any other Law relating to Taxes unless the applicable Securityholder shall have established to the reasonable satisfaction of Parent or the Surviving Corporation, as applicable, that such Tax either has been paid or is not applicable. To the extent that amounts are so withheld by the Paying Agent, Parent or the Surviving Corporation, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such withholding was made by the Paying Agent, Parent or the Surviving Corporation. Parent or the Surviving Corporation shall be responsible to pay, in due course, all applicable federal, state and local income Tax withholding and Social Security, Medicare, state disability, unemployment and other obligations for which amounts were withheld in respect of payments to the RSU Holders and payments of Change in Control Costs or otherwise withheld from payments made under this Agreement.

5.5 Dissenters’ Rights.

(a) In connection and included with the mailing of the Consent Solicitation, the Company shall provide each record holder of Common Stock with notice of such holder’s appraisal rights pursuant to Section 262 of the DGCL. The Company shall give Parent reasonably prompt notice (and in any event, no later than three (3) Business Days after receipt) of any demands for appraisal pursuant to Section 262 of the DGCL received by the Company from any Stockholders, withdrawals of such demands and any other instruments served pursuant to the DGCL and received by the Company in connection therewith. No later than ten (10) days following the Closing Date, Parent and the Surviving Corporation shall provide notice of the Closing Date to each Stockholder entitled to appraisal, in accordance with Section 262(d)(2) of the DGCL.

(b) Notwithstanding any other provision of this Agreement to the contrary, any outstanding shares of Common Stock that are held immediately prior to the Effective Time by Persons who have neither voted in favor of the Merger nor consented thereto in writing and who have demanded and perfected the right, if any, for appraisal of such outstanding shares of Common Stock in accordance with the provisions of Section 262 of the DGCL and have not withdrawn or lost such right to appraisal (collectively, the “Dissenting Shares”) shall be automatically cancelled and shall cease to exist and each holder of Dissenting Shares shall cease to have any rights with respect thereto, except the right to receive the fair value of such Dissenting Shares in accordance with the provisions of the DGCL. If a holder of Dissenting Shares thereafter withdraws or loses (through

failure to perfect or otherwise) the right to appraisal with respect to such Dissenting Shares, then, as of the occurrence of such withdrawal or loss, each such Dissenting Share shall be deemed to have been converted, at the Effective Time, into and represent only the right to receive, in accordance with Section 4.1, the Common Share Price and other consideration described in this Agreement, without interest thereon, except as expressly provided herein.

5.6 Post-Closing Adjustments.

(a) Following the Closing, the Surviving Corporation shall prepare a statement (the “Post-Closing Statement”) which shall contain or include (x) a reasonably detailed calculation of the Net Working Capital and (y) calculations of (i) the Approved Capital Expenditures, (ii) the NOL Tax Benefit, (iii) the Transaction Costs, (iv) the Change in Control Costs, (v) the aggregate amount of outstanding Debt of the Company Entities as of the Closing Time, and (vi) the estimated Final Adjustment Amount, and the Surviving Corporation shall deliver the same, together with the Closing Financial Statements, to the Securityholders Representative no later than the 45th day following the Closing Date; provided, however, that the Surviving Corporation shall have until the 60th day following the Closing Date to deliver the calculation of the NOL Tax Benefit to the Securityholders Representative, and, when delivered, such calculation of the NOL Tax Benefit shall be deemed part of the Post-Closing Statement.

(b) The Post-Closing Statement delivered by the Surviving Corporation to the Securityholders Representative shall be final and binding on the Parties, the Securityholders and the Securityholders Representative unless the Securityholders Representative objects within forty-five (45) days after receipt of the full Post-Closing Statement, including the calculation of the NOL Tax Benefit, by: (A) notifying the Surviving Corporation and Parent in writing of each objection thereto; and (B) delivering to the Surviving Corporation and Parent a statement describing the basis for each objection along with any modifications to the Post-Closing Statement proposed by the Securityholders Representative. The modified Post-Closing Statement as proposed by the Securityholders Representative shall be final and binding on the Parties, the Securityholders Representative and the Securityholders unless the Surviving Corporation objects in writing no later than the fifteenth (15th) day following the receipt of such modified Post-Closing Statement, which such notice to the Securityholders Representative shall contain a detailed statement describing the basis of each objection thereto and any modifications proposed by the Surviving Corporation.

(c) Any component of the Surviving Corporation’s Post-Closing Statement or the Securityholders Representative’s modified Post-Closing Statement that is not the subject of a proper and timely objection by the Surviving Corporation or the Securityholders Representative, as applicable, shall be final and binding on the Parties, the Securityholders and the Securityholders Representative. If the items disputed pursuant to Section 5.6(b) equal an aggregate amount in dispute that is less than the Adjustment Escrow Amount, then the aggregate amount so disputed shall be retained in the Adjustment Escrow Account and the Securityholders Representative and Parent shall deliver a joint written instruction to the Escrow Agent directing that the remaining

(a) The Company will adopt resolutions terminating any Employee Benefit Plan that is a defined contribution retirement plan (“Savings Plan”), and any other Employee Benefit Plan requested in writing by Parent to be terminated no later than seven (7) days prior to the Closing Date, in each case, effective not later than the day immediately preceding the Effective Time; provided, however, that Parent or an Affiliate of Parent will cause a tax-qualified Savings Plan of Parent to accept rollovers, including rollovers of loans, from any Savings Plan of the Company Entities with respect to Continuing Employees to the extent permitted under such Parent Savings Plan. The Company will provide Parent with evidence that the Savings Plans and such other Employee Benefit Plans have been terminated in accordance with this Section 9.8(a) pursuant to resolution of the Board (the form and substance of which will be subject to review and approval by Parent, such approval not to be unreasonably withheld, conditioned or delayed) not later than the day immediately preceding the Effective Time.

(b) Unless otherwise agreed in writing by Parent and the Company, the Company Entities shall terminate, as of the day immediately prior to the Closing, each officer or employee set forth on Schedule B. Parent shall take such action as may be necessary so that on and after the Effective Time officers and employees of the Company Entities who are in the employ of the Company Entities immediately prior to the Closing (“Continuing Employees”) are provided, for a period of twelve (12) months following the Closing Date, with (i) employee benefits, plans and programs on substantially the same basis as officers and employees of Parent and its Subsidiaries having similar responsibilities and positions (“Parent Benefit Plans”) and (ii) annual cash compensation (including annual rate of cash base salary and wage rates, as applicable, and target cash incentive opportunities) that are no less favorable than such annual cash compensation levels maintained for and provided to such Continuing Employees immediately prior to the Closing. For purposes of eligibility to participate and vesting, but not for benefit accrual purposes or for purposes of benefits under any defined benefit pension plan, in all Parent Benefit Plans, the Continuing Employees shall be credited with their years of service with the Company Entities and any predecessors thereof to the extent service with Parent and its Subsidiaries and any predecessors thereof is taken into account under such Parent Benefit Plans, except where the recognition of such service would result in a duplication of benefits with respect to the same period of service. The eligibility of any Continuing Employee to participate in any Parent Benefit Plan that is a welfare benefit plan or program shall not be subject to any exclusions for any pre-existing conditions if such individual has met the participation requirements of similar benefit plans and programs of the Company Entities subject, in the case of any insured arrangement, to the approval and agreement of the applicable insurer. Any amounts previously expended by Continuing Employees and their covered dependents under an Employee Benefit Plan for the plan year in which the Closing occurs for purposes of satisfying out-of-pocket requirements, deductibles and co-payments under any Employee Benefit Plan that is a welfare benefit plan or program for the benefit of any employee of any Company Entity shall be credited for purposes of satisfying such employee’s out-of-pocket requirements, deductibles and co-payments under any comparable Parent Benefit Plan; provided, however, that the Continuing Employees shall be responsible for providing the necessary

information to Parent based on “explanation of the benefits” forms received by the Continuing Employee from the Employee Benefit Plans maintained by the Company Entities. All individuals eligible to participate in any Company plan or arrangement contemplated above shall be immediately eligible to participate in the similar Parent Benefit Plan subject to the applicable terms and conditions of any such plan. Nothing contained in this Section 9.8(b) shall create any rights in any Continuing Employee or former officer or employee (including any beneficiary or dependent thereof) of the Company Entities or the Surviving Corporation in respect of continued employment for any specified period of any nature or kind whatsoever.

(c) Parent, Merger Sub and each Company Entity hereby agree that none of the provisions of this Section 9.8 is intended to, and does not, confer upon any Person other than the Parties any rights or remedies hereunder, including the right to enforce any obligations of Parent or the Merger Sub contained herein. Nothing in this Agreement, express or implied, shall be construed to prevent Parent or any of its Subsidiaries from: (i) terminating, or modifying the terms of employment of, any Continuing Employee following the Closing Date; or (ii) terminating or modifying to any extent any Employee Benefit Plan, Parent Benefit Plan or any other employee benefit plan, program, agreement or arrangement that Parent or any of its Subsidiaries may establish or maintain. Nothing in this Agreement shall be construed as an amendment to any Employee Benefit Plan, Parent Benefit Plan or any other compensation and benefit plans maintained for or provided to directors, officers or employees of Parent, its Subsidiaries or the Company Entities prior to or following the Closing Date.

9.9 Tax Treatment. The Parties agree that for federal and state income Tax purposes they shall treat the Merger as a sale of the Common Stock by the Stockholders to Parent.

9.10 Tax Matters.

(a) Filing of Tax Returns; Payment of Taxes. The Surviving Corporation shall prepare or cause to be prepared all Tax Returns of the Company and its Subsidiaries required to be filed after the Closing Date for all Pre-Closing Periods and all Straddle Periods. Such Tax Returns shall be prepared on a basis consistent with past practice except to the extent otherwise required by applicable Law. Reasonably in advance of filing, which for purposes of income Tax Returns shall be no later than thirty (30) days prior to the due date for filing any such Tax Return, the Surviving Corporation shall deliver a copy of such Tax Return, together with all supporting documentation and workpapers, to the Securityholders Representative for its review and reasonable comment. The Surviving Corporation shall cause such Tax Return (as revised to incorporate the Securityholders Representative’s reasonable comments) to be timely filed and shall provide a copy to the Securityholders Representative.

(b) Proration of Straddle Period Taxes. In the case of Taxes that are payable with respect to any Straddle Period, the portion of any such Taxes that is attributable to the portion of the period ending on the Closing Date shall be:

(i) in the case of Taxes that are either: (A) based upon or related to income or receipts; or (B) imposed in connection with any sale or other transfer or assignment of property (real or personal, tangible or intangible), deemed equal to the amount that would be payable if the Tax period of the Company and its Subsidiaries (and each partnership in which the Company and its Subsidiaries is a partner) ended with (and included) the Closing Date; provided, however, that exemptions, allowances or deductions that are calculated on an annual basis (including depreciation and amortization deductions) shall be allocated between the period ending on and including the Closing Date and the period beginning after the Closing Date in proportion to the number of days in each period;

(ii) in the case of Taxes that are imposed on a periodic basis with respect to the assets or capital of the Company or any Subsidiary, deemed to be the amount of such Taxes for the entire Straddle Period (or, in the case of such Taxes determined on an arrears basis, the amount of such Taxes for the immediately preceding period), multiplied by a fraction the numerator of which is the number of calendar days in the portion of the period ending on and including the Closing Date and the denominator of which is the number of calendar days in the entire period; and

(iii) any franchise Tax shall be allocated to the period during which the income, operations, assets or capital comprising the base of such Tax is measured, regardless of whether the right to do business for another period is obtained by payment of such franchise Tax.

(i) The Surviving Corporation and the Securityholders Representative agree that any Tax refunds and interest thereon payable to the Company with respect to any Tax Period ending on or before the Closing Date shall be for the account of the Securityholders (other than any refund (A) resulting from the carryback or carryforward of a net operating loss, (B) reflected in the calculation of Net Working Capital, or (C) resulting from any other Tax attribute from a period beginning after the Closing Date to a period ending on or prior to the Closing Date, which refund shall be for the account of the Surviving Corporation). The amount of any refunds of Taxes of the Company for any Tax period beginning after the Closing Date shall be for the account of the Surviving Corporation. The amount of any refund of Taxes of the Company for any Straddle Period shall be equitably apportioned between the Securityholders and the Surviving Corporation in accordance with the principles set forth in Section 9.10(b). Within thirty (30) days after receipt of each such federal, state or local income Tax refund,

the Surviving Corporation shall pay to the Securityholders an amount equal to any refund and interest thereon the Securityholders are entitled to receive pursuant to this Section 9.10(c), net of reasonable costs or expenses incurred by the Surviving Corporation in procuring such refund (and any such payments to the Securityholders shall be made pro rata in accordance with their Percentage Share); provided, however, in the event there are Seller Taxes that have not been recovered pursuant to the terms of Article XI, and there are not sufficient funds in the Fixed Escrow Account to pay such Seller Taxes, the Surviving Corporation shall be entitled to retain such refund to the extent of such unrecovered Seller Taxes.

(ii) The Securityholders Representative shall have the right to control the conduct and settlement of, and represent the Surviving Corporation’s interest in, any Tax Proceeding relating to taxable periods ending on or before the Closing Date, and to employ counsel of its choice for such purpose. The Surviving Corporation shall have the right to participate in such Tax Proceeding at its own expense, and shall be entitled to control the disposition of any issue involved in such Tax Proceeding that does not relate to or affect a Seller Tax and that is not otherwise subject to indemnification by the Securityholders hereunder. The Securityholders Representative and the Surviving Corporation shall be entitled to represent their own interests in light of their responsibilities (including indemnity obligations) for Taxes, at their own expense, in any Tax Proceeding involving a taxable period that includes but does not end on the Closing Date. Notwithstanding the foregoing provisions of this Section 9.10, neither the Securityholders Representative nor the Surviving Corporation shall agree to any settlement with respect to any Tax Proceeding of the Surviving Corporation without the consent of the other Person if such settlement could reasonably be expected to affect, respectively, any Tax liability of the Securityholders or the Surviving Corporation, as applicable, that is not an indemnified Tax.

(iii) Unless required by applicable Law or except as set forth below, the Surviving Corporation shall not amend any Tax Return or election made in connection with such Tax Return for any Tax Period ending on or before the Closing Date without the prior written consent of the Securityholders Representative. Parent and the Surviving Corporation shall not, and shall cause their respective Affiliates to not, request that any tax examination be initiated with respect to any of the matters set forth on Schedule N. Notwithstanding the foregoing, the Surviving Corporation may file or cause to be filed an amended Tax Return even if not required by applicable Law without the consent of the Securityholders

Representative; provided, however, that any additional Taxes resulting therefrom shall not constitute Seller Taxes and no indemnification may be asserted under Article XI with respect to any such additional Taxes

(iv) If all or any portion of a refund to which the Securityholders are entitled and have received payment of pursuant to this Section 9.10(c) is required to be repaid or otherwise disallowed by any Taxing Authority, the amount of such refund required to be repaid or disallowed shall constitute a Parent Indemnifiable Loss.

(d) Tax Cooperation. The Surviving Corporation and the Securityholders Representative shall reasonably cooperate with each other in connection with the preparation of Tax Returns related to the Surviving Corporation and any audit, litigation or other Proceeding with respect to Taxes imposed on the Surviving Corporation. The Surviving Corporation shall preserve all information and Records relating to any liabilities for Taxes with respect to a Tax Period until the later of the expiration of all applicable statutes of limitation and extensions thereof or a final determination with respect to Taxes for such period and shall not destroy or otherwise dispose of any Record without first providing the other Person a reasonable opportunity to review and copy the same. The Surviving Corporation shall permit the Securityholders Representative and its counsel, accountants and other advisors reasonable access (with the right to make copies) to the financial books and records of the Surviving Corporation and its counsel, accountants and other advisors (and their workpapers) for the purposes of this Section 9.10. The Securityholders Representative agrees, upon request, to use commercially reasonable efforts to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed on the Surviving Corporation (including with respect to the transactions contemplated hereby).

(e) Transfer Taxes. All state and local transfer, sales, use, stamp, registration or other similar Taxes (the “Transfer Taxes”) resulting from the transactions contemplated by this Agreement shall be borne 50% by the Securityholders (and such 50% shall be considered Transaction Costs, to the extent determinable as of the Closing Time, or Seller Taxes, to the extent not determinable as of, or otherwise paid at, the Closing Time) and 50% by Parent.

9.11 No Solicitation; Other Offers.

(a) Except as expressly permitted pursuant to Section 9.11(b) and Section 9.11(c), the Company shall not, and it shall cause its Subsidiaries and their respective Representatives not to, directly or indirectly: (i) solicit, initiate, entertain or knowingly encourage (including by way of providing information) the submission or announcement of any inquiries, proposals or offers that constitute or would reasonably be expected to lead to any Takeover Proposal; (ii) provide any non-public information concerning the Company or any of its Subsidiaries to any Person or group who would reasonably be expected to make any actual or proposed Takeover Proposal; (iii) engage

(b) Notwithstanding anything to the contrary contained in this Section 9.11, if at any time prior to obtaining the Stockholder Consent, the Company or any of its Representatives receives a Takeover Proposal that was made or renewed after the date of this Agreement and did not result from or arise in connection with any breach of Section 9.11(a) and the Board (or a duly constituted committee thereof) determines in good faith, after consultation with its outside financial advisors and outside legal counsel, that the failure to take any of the following actions would be inconsistent with the Board’s fiduciary duties under applicable Law, then (i) the Company and its Representatives may provide information (including non-public information) to the applicable Bidder or provide access to the books, assets and personnel of the Company, and (ii) engage in any discussions or negotiations with such Bidder and its Representatives; provided that the Company shall only permit non-public information related to the Company to be provided pursuant to an Acceptable Confidentiality Agreement and, provided further, that the Company shall (A) deliver written notice to Parent no later than one (1) day after taking any action permitted pursuant to this Section 9.11(b) and, to the extent not previously delivered pursuant to Section 9.11(d), deliver a copy (or, if not in writing, an accurate written summary and description, including all material terms and information conveyed pursuant thereto) of the Takeover Proposal and any other materials, communication or information received by the Company or any of its Representatives (whether written or oral) in connection with or pursuant to such Takeover Proposal to Parent; (B) shall promptly (and in any event within 24 hours of providing such non-public information to the Bidder) provide to Parent any such non-public information that was not previously provided or made available to Parent; (C) within 24 hours of the Board’s (or a duly constituted committee thereof), the Company’s or any of its Representative’s receipt thereof, deliver a copy of (or, if not in writing, an accurate written summary and description, including all material terms and information conveyed pursuant thereto) any revisions, amendments, supplements or modifications to the Takeover Proposal or an updated Takeover Proposal and any other additional material documents, communications or information received by the Board (or a duly constituted committee thereof), the Company or any of its Representatives (whether written or oral) in connection with or pursuant to such Takeover Proposal; and (D) shall keep Parent reasonably informed orally and in writing as to the status of any material developments concerning the Takeover Proposal,

including prompt written notice to Parent of any determination by the Board (or a duly constituted committee thereof) that a Superior Proposal has been made.

(c) If the Board (or a duly constituted committee thereof) determines in its good faith judgment, after consultation with its outside financial advisors and outside legal counsel, that such Takeover Proposal constitutes a Superior Proposal and that the failure to take any of the following actions would be inconsistent with the Board’s fiduciary duties under applicable Law, then, (i) the Board may effect a Company Adverse Recommendation Change, (ii) the Company may waive, modify, amend or release any standstill or similar provisions with respect to such Superior Proposal and (iii) the Company or its Subsidiaries may enter into a definitive agreement to consummate such Superior Proposal if the Company shall have, concurrently with entering into such agreement, terminated this Agreement pursuant to Section 12.1(e); provided, that during the two Business Day-notice period referred to in Section 9.11(d), the Company shall (I) be prohibited from taking any of the actions set forth in clauses (i) — (iii), and (II) have negotiated in good faith with Parent and Merger Sub (to the extent Parent and Merger Sub desire to negotiate) to permit Parent and Merger Sub to make adjustments to the terms and conditions of this Agreement (as adjusted, a “Matching Bid”) as may be necessary to make the Merger contemplated under such Matching Bid equivalent to, or better than, the Superior Proposal.

(d) The Company shall promptly (and, in any event, within one (1) Business Day after receipt thereof) notify Parent in writing in the event the Company, any of its Subsidiaries or any of their respective Representatives receives a Takeover Proposal, any request for non-public information concerning the Company or any of its Subsidiaries from any Person who would reasonably be expected to make a Takeover Proposal, or any request for discussions or negotiations related to any Takeover Proposal or potential Takeover Proposal (including any material changes related to the foregoing). Such notice shall include the identity of the Person making such Takeover Proposal or request and the material terms and conditions thereof (including, if applicable, copies of any written requests, proposals or offers, including proposed agreements). The Company shall provide Parent at least two (2) Business Days prior written notice that the Board intends to make a Company Adverse Recommendation Change, which such notice shall include copies of all proposed definitive agreements with respect to the Superior Proposal.

(e) Except as expressly permitted pursuant to this Section 9.11, the Board shall not grant any waiver or release under any “standstill agreement” with respect to any class of Equity Interests of the Company. The Company shall not, and shall not permit its Subsidiaries or any of their respective Representatives to, enter into any confidentiality agreement subsequent to the date of this Agreement that prohibits the Company from providing to Parent the information specifically required to be provided to Parent pursuant to this Section 9.11.

(f) Nothing contained in this Section 9.11 shall prohibit the Company from making any disclosure to the Stockholders that, in the good faith determination of the Board, after consultation with its outside legal counsel, is required by applicable Laws.

(i) any breach or inaccuracy of any representation or warranty made by the Company under Article VII or in the Company Closing Certificate; provided, however, that, solely for purposes of calculating Parent Indemnifiable Losses, if any such representation or warranty is qualified by the use of the term “Material Adverse Effect” or by the word “material” or by any word formed from such words, then such representation or warranty shall be construed as if the word “material” (and such words formed therefrom) or the term “Material Adverse Effect” were not included in such representation or warranty;

(c) Notwithstanding any provision of this Agreement to the contrary, in no event shall Company Indemnifiable Losses include any Parent Indemnifiable Losses.

11.3 Limits on Indemnification.

(a) Aggregate Liability. The aggregate liability of Parent and the Surviving Corporation to indemnify the Company Indemnitees from and against any Company Indemnifiable Losses shall be limited, in the aggregate, to an amount equal to the Fixed Escrow Amount. The aggregate liability of the Securityholders to indemnify the Parent Indemnitees from and against any Parent Indemnifiable Losses shall be limited to the

Fixed Escrow Amount and the amounts from time to time available in the Fixed Escrow Account shall be the Parent Indemnitees sole recourse in respect of any Parent Indemnifiable Losses. Without limitation of the foregoing, the aggregate liability of the Securityholders to indemnify the Parent Indemnitees from and against any and all Parent Indemnifiable Losses relating to claims asserted under Sections 11.2(a)(i)-(xii) shall be limited to the amounts from time to time remaining in the General Indemnity Escrow and, subject to Schedule N, the Regulatory Indemnity Escrow and in no event shall any Parent Indemnitees be entitled to assert any indemnification claims relating to Sections 11.2(a)(i)-(xii) against the Specific Indemnity Escrow or the Waiver Escrow, it being understood that the Parties have agreed that the Parent Indemnitees sole recourse in respect of any Parent Indemnifiable Losses relating to (A) claims asserted under Sections 11.2(a)(i)-(xii) shall be the amounts from time to time available in the General Indemnity Escrow and the Regulatory Indemnity Escrow and (B) claims asserted under Sections 11.2(a)(xiii) shall be the amounts set forth on Schedule N.

(b) Deductible Threshold. The Parent Indemnitees shall not be entitled to be indemnified for Parent Indemnifiable Losses pursuant to Section 11.2(a)(i) and Sections 11.2(a)(iv)-(xii) unless and until the aggregate amount of all such Parent Indemnifiable Losses exceeds $2,000,000 (the “Deductible Threshold”); provided, however, that the Parent Indemnitees shall not be entitled to be indemnified pursuant to Section 11.2(a)(i) and Sections 11.2(a)(iv)-(xii) for any Losses with respect to any individual items or matter unless the amount thereof exceeds $20,000 (the “De Minimis Threshold”), and if the De Minimis Threshold is not exceeded with respect to any individual Loss, then none of the Losses with respect to such item or matter will count toward satisfying the Deductible Threshold. Notwithstanding the foregoing, the Deductible Threshold and De Minimis Threshold shall not apply to (and the Parent Indemnitees shall be entitled to be indemnified for all Parent Indemnifiable Losses relating to) any claims asserted under Section 11.2(a)(i) insofar as such claims relate to (1) any breach of a Company Fundamental Representation, (2) any breach of the representations set forth in clauses (a)-(c) of Section 7.2 (or, in the case of clauses (1) and (2), to the extent related to any such representations and warranties, any breach of any certificate delivered by or on behalf of the Company to Parent prior to or at the Closing in connection with this Agreement), (3) the certification in the Company Closing Certificate relating to the matters set forth in Section 10.1(a)(xviii) and Section 10.1(a)(xix), or (4) any claims asserted under Section 11.2(a)(ii), Section 11.2(a)(iii) and Section 11.2(a)(xiii). Parent Indemnifiable Losses from any claims to which the Deductible Threshold does not apply shall not be considered in the calculation of the Deductible Threshold. Subject to the foregoing, after the Deductible Threshold is exceeded, the Parent Indemnitees shall be entitled to be paid the entire amount of any Parent Indemnifiable Losses pursuant to Section 11.2(a)(i) and Sections 11.2(a)(iv)-(xii) in excess of (but not including) the Payment Indemnifiable Losses previously included in the calculation of the Deductible Threshold, subject to the other limitations on recovery and recourse set forth in this Agreement.

(i) No Indemnifying Party shall be liable for any Indemnifiable Losses unless a written claim for indemnification under this Agreement is delivered by the Indemnified Person to the Indemnifying Party with respect thereto prior to the General Indemnification Termination Date or, with respect to the matters set forth on Schedule N, to the extent permitted and contemplated by Schedule N; provided, however, that claims for any Indemnifiable Losses validly asserted hereunder prior to the General Indemnification Termination Date or, with respect to the matters set forth on Schedule N, to the extent permitted and contemplated by Schedule N, shall survive until they are finally resolved pursuant to the terms hereof and the Escrow Agreement. Notices to the Securityholders as Indemnifying Parties need only be furnished to the Securityholders Representative.

(ii) No matter that gives rise to an adjustment under Section 5.6, will be the subject of or eligible for a claim by any Parent Indemnitee for indemnification under this Article XI; provided that, Parent shall have the right to withdraw funds from the Fixed Escrow Account to the extent permitted by Sections 5.6(g) and 5.6(h).

(iii) Without limitation, the indemnification obligations set forth in this Article XI also shall be subject to the limitations set forth in Section 9.7(c) and Section 13.16.

(iv) Without limitation of Section 9.7(c), the liability of the Securityholders to indemnify the Parent Indemnitees pursuant to Section 11.2(a)(i) shall not include Parent Indemnifiable Losses relating to a breach by the Company of any of its representations and warranties set forth in Article VII (excluding Section 7.22) of which any of the officers of Parent (or its Affiliates) listed in the definition of “Knowledge” has actual conscious awareness as of the time of the execution and delivery of this Agreement by Parent. For the avoidance of doubt, subject to Section 9.7(c), the foregoing waiver in this Section 11.3(c)(iv) does not apply to any indemnity set forth in Section 11.2(a)(v) - 11.2(a)(xiii).

(d) Cooperation. An Indemnified Person shall, at the Indemnifying Party’s request and expense, cooperate in the defense of any matter subject to indemnification hereunder.

(e) Reduction for Tax Benefit or Loss; Insurance. The amount of any Indemnifiable Losses payable under Article XI by an Indemnifying Party shall be reduced by (i) the net present value of Tax savings or benefits actually realized by the Indemnified Person that is attributable to any deduction, loss, credit or other Tax benefit resulting from or arising out of such Indemnifiable Losses and (ii) all proceeds from

insurance or other third party indemnification actually received by the Indemnified Person.

(f) Mitigation. Each Indemnified Person shall take and shall cause its respective Affiliates to take all reasonable steps to mitigate and otherwise minimize the Indemnifiable Losses to the maximum extent reasonably practicable upon and after becoming aware of any event which would reasonably be expected to give rise to any Indemnifiable Losses. Notwithstanding the foregoing, no failure on the part of any Indemnified Person to satisfy its obligations under this Section 11.3(f) shall relieve any Indemnifying Party from its indemnification obligation under Article XI of this Agreement; provided, however, that the foregoing shall not limit or affect an Indemnifying Party’s remedies for breach of this Section 11.3(f) that are otherwise available pursuant to this Agreement or applicable Law.

(g) Sole and Exclusive Remedy; Fraud. THE RIGHTS OF INDEMNITY PROVIDED IN THIS ARTICLE XI ARE THE PARTIES’, THE SECURITYHOLDERS REPRESENTATIVE’S AND THE SECURITYHOLDERS’ SOLE AND EXCLUSIVE REMEDY AFTER THE EFFECTIVE TIME RELATING IN ANY WAY TO A BREACH OF THIS AGREEMENT. Notwithstanding any other provision of this Agreement to the contrary, the liability of any Person under this Article XI shall be in addition to, and not exclusive of, any other liability that such Person may have at law or equity based on such Person’s fraudulent acts, fraudulent omissions or intentional misrepresentation. None of the provisions set forth in this Agreement, including the provisions set forth in this Section 11.3, shall be deemed a waiver by any Person of (or a limitation on) any right or remedy that such Person may have at law or equity based on any other Person’s fraudulent acts, fraudulent omissions or intentional misrepresentation.

(h) Characterization of Payments. The Parties shall treat any payments made pursuant to this Article XI as an adjustment to the purchase price for federal Tax purposes, unless a final determination (which shall include the execution of a Form 870-AD or successor form) with respect to the Surviving Corporation causes such payment not to be treated as an adjustment to, or refund of, the purchase price for federal Tax purposes.

11.4 Matters Involving Third Parties.

(a) If any third party shall notify any Indemnified Person with respect to any matter (a “Third Party Claim”) which may give rise to a claim for indemnification against an Indemnifying Party under this Article XI, the Indemnified Person shall promptly notify the Indemnifying Party thereof in writing; provided, however, that no delay on the part of the Indemnified Person in notifying the Indemnifying Party shall relieve the Indemnifying Party from any obligation hereunder unless (and then solely to the extent) the Indemnifying Party is actually and materially prejudiced thereby. The notice described in this Section 11.4(a) shall describe the Third Party Claim in reasonable detail to the extent known, and shall indicate the amount (estimated, if necessary and if then estimable) of the Indemnifiable Loss that has been or may be suffered.

(b) The Indemnifying Party shall have the right to defend the Indemnified Person against the Third Party Claim with counsel of the Indemnifying Party’s choice, reasonably satisfactory to the Indemnified Person, so long as: (i) the Indemnifying Party notifies the Indemnified Person, within thirty (30) days after the Indemnified Person has given written notice of the Third Party Claim to the Indemnifying Party (unless in such notice the Indemnified Person certifies, in good faith, that the failure to assume such defense within fifteen (15) days would materially prejudice the Indemnified Person by a delay in assuming the defense beyond fifteen (15) days, in which case, the Indemnified Person shall have the right to assume the defense subsequent to the expiration of such fifteen (15) day period if the Indemnifying Party fails to so assume the defense thereof as provided in and subject to Section 11.4(d)), that the Indemnifying Party is assuming the defense of such Third Party Claim and shall indemnify the Indemnified Person against such Third Party Claim in accordance with the terms and limitations of this Article XI; and (ii) the Indemnifying Party conducts the defense of the Third Party Claim in an active and diligent manner.

(c) So long as the conditions set forth in Section 11.4(b) are and remain satisfied: (i) the Indemnifying Party may conduct the defense of the Third Party Claim in accordance with Section 11.4(b); (ii) the Indemnified Person may retain separate co-counsel at its sole cost and expense (provided, however, that the Indemnifying Party shall pay the attorneys’ fees of the Indemnified Person if (A) the employment of separate counsel shall have been authorized in writing by the Indemnifying Party in connection with the defense of such Third Party Claim or (B) the Indemnified Person’s counsel shall have advised the Indemnified Person in writing, with a copy delivered to the Indemnifying Party, that there is a conflict of interest that would make it inappropriate under applicable standards of professional conduct to have common counsel; and (iii) the Indemnifying Party may not, without the prior written consent of the Indemnified Person (which consent shall not be unreasonably withheld, conditioned or delayed), enter into a settlement with respect to a Third Party Claim; provided that, the Indemnifying Party may, without the prior written consent of the Indemnified Person, enter into a settlement of a Third Party Claim so long as it (1) does not impose an injunction or other equitable relief upon the Indemnified Person, (2) involves the payment of money damages for which sufficient funds remain in the Fixed Escrow Account and (3) includes an unconditional provision whereby the plaintiff or claimant in the matter releases the Indemnified Person and all of its Affiliates and Representatives from all liability with respect thereto.

(d) Notwithstanding Sections 11.4(b) and 11.4(c), the Indemnifying Party shall not be entitled to control (but shall be entitled to participate at its own expense in the defense of), and the Indemnified Person shall be entitled to have sole control over, the defense or settlement, compromise, admission or acknowledgment of any Third Party Claim: (i) as to which the Indemnifying Party fails to assume the defense within thirty (30) days after the Indemnified Person gives notice thereof to the Indemnifying Party (unless in such notice the Indemnified Person certifies, in good faith, that the failure to assume such defense within fifteen (15) days would materially prejudice the Indemnified Person by a delay in assuming the defense beyond fifteen (15) days), in which case, the Indemnified Person shall have the right to assume the defense subsequent to the

expiration of such fifteen (15) day period if the Indemnifying Party fails to so assume the defense thereof); (ii) to the extent the Third Party Claim seeks an Order, injunction or other equitable relief against the Indemnified Person which, if successful, would adversely affect in any material respect the business, operations, assets or financial condition of the Indemnified Person; (iii) in the case where the Indemnifying Party fails to satisfy its obligations under Section 11.4(b)(ii) or Section 11.4(c)(ii); or (iv) in the case where the Securityholders are the Indemnifying Party and the Third Party Claim in issue and the Indemnified Losses in connection therewith involve or are reasonably likely to involve an amount in excess of 150% of the amount remaining in the applicable portion of the Fixed Escrow Amount available for the satisfaction of such Third Party Claim and Parent Indemnifiable Losses (after taking into account the other unresolved Parent Indemnifiable Losses asserted in good faith against such portion of the Fixed Escrow Amount). Notwithstanding anything to the contrary in this Section 11.4, if an Indemnified Person assumes control of the defense of any Third Party Claim, the costs incurred by such Indemnified Person in connection with the defense of such Third Party Claim shall not be included in the calculation of Indemnifiable Losses relating to such Third Party Claim and shall be paid solely by the Indemnified Person; provided that, nothing in this Section 11.4(d) shall limit the Parent’s or the Surviving Corporation’s right to recover legal fees as and to the extent set forth on Schedule N.

(e) If an Indemnified Person assumes the control of the defense of any Third Party Claim in accordance with the provisions of this Section 11.4, such Indemnified Person may enter into any settlement, compromise, admission or acknowledgement of the validity of such Third Party Claim without obtaining the prior written consent of the Indemnifying Party; provided, however, that the Indemnified Person shall make no settlement, compromise, admission or acknowledgment that would (i) pursuant to its terms, impose any liability or obligation (under this Article XI or otherwise) on the part of the Indemnifying Party or (ii) any admission that the Securityholders in their capacity as Securityholders were at fault in connection with matter, omission or event giving rise to the Third Party Claim, in each case without the prior written consent of the Indemnifying Party.

(f) If an Indemnified Person assumes control of the defense of any Third Party Claim in accordance with the provisions of Section 11.4(d)(ii) or (iv) and a judgment or arbitral award is rendered against such Indemnified Person or any of its Affiliates, then the Indemnifying Party shall be liable for only 50% of the Losses otherwise subject to indemnification hereunder with respect to such judgment or arbitral award.

(g) Notwithstanding anything to the contrary, the control, defense and prosecution of the Schedule M Filings shall be governed exclusively by Section 9.1(e) and Schedule Q.

11.5 Direct Claims. In any case in which an Indemnified Person seeks indemnification hereunder that is not subject to Section 11.4 because no Third Party Claim is involved, the Indemnified Person shall notify the Indemnifying Party in writing of any Indemnifiable Losses that such Indemnified Person claims are subject to indemnification under the terms hereof. The

notice shall describe the indemnification sought in reasonable detail to the extent known, and shall indicate the amount (estimated, if necessary and if then estimable) of the Indemnifiable Loss that has been or may be suffered. Subject to the limitations set forth in Sections 11.1 and 11.3, the failure of the Indemnified Person to exercise promptness in such notification shall not amount to a waiver of such claim unless and only to the extent that the resulting delay materially and adversely prejudices the position of the Indemnifying Party with respect to such claim.

11.8 Schedule N. The terms and provisions of this Article XI are subject in all respects to the terms and conditions of Schedule N.

(e) Parent may terminate this Agreement by written notice to the Company if, as of immediately prior to the Closing, any one or more of the representations and warranties of the Company set forth in Article VII is not true, correct and complete in all material respects and the failure, individually or in the aggregate, to be so true, correct and complete in all material respects would reasonably be expected to be adverse to the Company Entities, taken as a whole, or the business of the Company Entities, taken as a whole, in any material respect (determined as if such representations and warranties were made as of the date hereof and as of immediately prior to the Closing, except for any such representations and warranties made as of a specified date, which shall be true and correct as of such specified date); provided that, for purposes of determining whether the foregoing standard has been met, all “Material Adverse Effect,” materiality and similar qualifiers contained in the representations and warranties set forth in Article VII shall be disregarded for all purposes; and, provided further that, the foregoing shall not be deemed, interpreted or construed to mean (or require Parent to establish the occurrence of) a Material Adverse Effect;

100

implementing the Superior Proposal and (ii) pays the Break-Up Fee to Parent contemporaneously with the delivery in clause (i).

For purposes of Sections 12.1(d) and 12.1(e), Parent and Merger Sub shall not be entitled to exericse their termination rights pursuant thereto as a result of any breach by the Company of any of its representations and warranties of which any of the officers of Parent (or its Affiliates) listed in the definition of “Knowledge” had actual conscious awareness as of the time of the execution and delivery of this Agreement by Parent.

(c) Any Break-Up Fee or Reverse Break-Up Fee owed pursuant to this Section 12.3 shall be due and payable in full contemporaneously with the termination of this Agreement.

(ii) $150,000 for the second year after the date of this Escrow Agreement; and

(iii) $100,000 for the third year after the date of this Escrow Agreement.

4. Other Disbursement Matters.

(a) The Escrow Agent shall comply with judgments or orders issued or process entered by any court with respect to the Escrow Funds, including, without limitation, any attachment, levy or garnishment, without any obligation to determine such court’s jurisdiction in the matter and in accordance with its normal business practices. If the Escrow Agent complies with any such judgment, order or process, then it shall not be liable to the Securityholders Representative, the Securityholders, Parent, the Surviving Corporation or any other person by reason of such compliance, regardless of the final disposition of any such judgment, order or process.

(b) In the event that the Parties deliver funds transfer instructions, whether in writing, by facsimile, electronic mail or otherwise, the Escrow Agent is authorized to seek confirmation of such instructions by telephone call to the authorized person or persons of the Parties delivering such instructions, and the Escrow Agent may rely upon the confirmations of anyone purporting to be the person or persons so designated. The persons and telephone numbers for callbacks may be changed only in a writing actually received and acknowledged by the Escrow Agent. The Parties agree that such security procedure is commercially reasonable.

(c) The Escrow Agent shall furnish monthly statements to each of the Securityholders Representative and Parent setting forth the activity in the Escrow Accounts. In addition, the Escrow Agent shall notify the Securityholders Representative and Parent in writing promptly after the release of funds in excess of $1,000,000 from any Escrow Account, which notice shall specify the amount of such release.

(d) In the event that the Escrow Agent makes any payment to the Securityholders Representative or Parent pursuant to this Escrow Agreement and for any reason such payment (or any portion thereof) is required to be returned to an Escrow Account or another Person or is subsequently invalidated, declared to be fraudulent, set aside and/or required to be repaid to a receiver, trustee or other Person under any bankruptcy or insolvency law, other federal or state law, common law or equitable doctrine, the Securityholders Representative and Parent irrevocably authorize the Escrow Agent to deduct any such amounts from the General Indemnity Escrow Funds without prior notice or demand to any Person (provided that the Escrow Agent shall provide the Securityholders Representative

and Parent prompt written notice following any such deductions). Any amounts deducted from the General Indemnity Escrow Funds due to non-payment by the Securityholders Representative pursuant to the foregoing sentence shall reduce any amounts payable to Payment Agent for disbursement to the Securityholders out of the General Indemnity Escrow Funds without prior notice or demand to any Person; provided that the Escrow Agent shall provide the Securityholders Representative and Parent prompt written notice following any such reductions and further provided that any such deduction shall be treated as a Liquidated Claim (as such term is defined in the Merger Agreement). If the amount of the General Indemnity Escrow Funds is insufficient to pay any fees and expenses due to the Escrow Agent by the Securityholders Representative pursuant to the foregoing sentence then the Securityholders Representative shall be obligated to collect such fees and expenses from the Securityholders pursuant to the Merger Agreement and remit such funds so collected promptly to the Escrow Agent. Any amounts deducted from the General Indemnity Escrow Funds due to non-payment by shall reduce any amounts payable to Parent out of the General Indemnity Escrow Funds and, to the extent there are insufficient funds validly payable to Parent out of the General Indemnity Escrow Funds, Parent shall pay to the Payment Agent for disbursement to the Securityholders any amounts deducted from any portion of the General Indemnity Escrow Funds validly payable to the Securityholders hereunder.

(e) The Securityholders Representative may instruct that the Escrow Agent deliver any Escrow Funds that are otherwise to be delivered to the Payment Agent for disbursement to the Securityholders in accordance with the terms of this Agreement to the Securityholders Representative to satisfy any amounts that are owing, or that the Securityholders Representative reasonably believes may become owing, to the Securityholders Representative under Section 2.4 of the Merger Agreement.

5. Fees and Expenses. The Securityholders Representative and Parent shall be responsible for, and shall pay to the Escrow Agent on demand, the Escrow Agent’s fees in connection with the services rendered by the Escrow Agent hereunder, as set forth on Schedule A attached hereto, and will reimburse the Escrow Agent for all reasonable other out-of-pocket expenses paid or incurred by it in the performance of its duties under this Escrow Agreement (including, without limitation, overnight delivery charges and reasonable fees of outside attorneys). Such fees and expenses shall be borne one-half by the Securityholders Representative and one-half by Parent; provided that the fees and expenses owed by the Securityholders Representative (including pursuant to Section 6(e)) shall be deducted from the account established pursuant to the Securityholders Representative Escrow Agreement as and when due and owing. If the fees and expenses due to the Escrow Agent by Parent hereunder are not paid when due, or if the Parent’s obligations to the Escrow Agent under Section 6(e) hereof are not satisfied on demand, then the Securityholders Representative and Parent irrevocably authorize the Escrow Agent to deduct any such amounts from the General Indemnity Escrow Funds without prior notice or demand to any Person (provided that the Escrow Agent shall provide the

Securityholders Representative and Parent prompt written notice following any such deductions). Any amounts deducted from the General Indemnity Escrow Funds due to non-payment by Parent pursuant to the foregoing sentence shall reduce any amounts payable to Parent out of the General Indemnity Escrow Funds and, to the extent there are insufficient funds validly payable to Parent out of the General Indemnity Escrow Funds, Parent shall pay to the Payment Agent for disbursement to the Securityholders any amounts deducted from any portion of the General Indemnity Escrow Funds validly payable to the Securityholders hereunder. If the amount deposited pursuant to the Securityholders Representative Escrow Agreement is insufficient to pay any fees and expense due to the Escrow Agent by the Securityholders Representative pursuant to this Escrow Agreement (including pursuant to Section 6(e)), then the Securityholders Representative and Parent irrevocably authorize the Escrow Agent to deduct any such amounts from the General Indemnity Escrow Funds without prior notice or demand to any Person (provided that the Escrow Agent shall provide the Securityholders Representative and Parent prompt written notice following any such deductions). If the amount of the General Indemnity Escrow Funds is insufficient to pay any fees and expenses due to the Escrow Agent by the Securityholders Representative pursuant to the foregoing sentence then the Securityholders Representative shall be obligated to collect such fees and expenses from the Securityholders pursuant to the Merger Agreement and remit such funds so collected promptly to the Escrow Agent. Any amounts deducted from the General Indemnity Escrow Funds due to non-payment by the Securityholders Representative pursuant to the foregoing sentence shall reduce any amounts payable to Payment Agent for disbursement to the Securityholders out of the General Indemnity Escrow Funds. If the amount of the General Indemnity Escrow Funds is insufficient to pay any fees and expenses due to the Escrow Agent by Parent or the Securityholders Representative pursuant to this Escrow Agreement, then, upon written notice to Parent and the Securityholders Representative, the Escrow Agent may suspend performance of its obligations under this Escrow Agreement until it has been paid all such fees and expenses, without incurring any liability to any person.

6. Duties; Liabilities and Indemnification.

(a) The Escrow Agent shall have only those duties and responsibilities as are expressly set forth herein, and no other duty, obligation or covenant, fiduciary or otherwise, shall be implied or enforceable against the Escrow Agent by any person.

(b) Without limiting the effect of Section 6(a) hereof, the Escrow Agent shall have no obligation or liability to the Securityholders Representative, Parent or the Surviving Corporation (or any Person claiming through any of them): (i) to review, examine, enforce, administer or take notice of any agreement, instrument or document other than this Escrow Agreement and any notices delivered pursuant to the terms hereof; (ii) to evaluate or determine the validity or legality of any action or omission by any other person; (iii) to make any payment to the Securityholders Representative (or the Payment Agent or the Securityholders), Parent or the Surviving Corporation from any source other than the Escrow

Accounts; (iv) to communicate with any person other than as expressly provided in this Escrow Agreement; (v) for any action or omission of the Escrow Agent taken or made upon the written instructions of the Securityholders Representative or Parent in accordance with the terms of this Escrow Agreement; (vi) for any action or omission of any third party or any federal or state bank regulator; (vii) for any other action or omission of the Escrow Agent under or in connection with this Escrow Agreement taken or made in good faith and without gross negligence or willful misconduct; and (viii) for special, incidental, consequential, indirect or punitive damages in any event (other than in the case of gross negligence or willful misconduct), even if the Escrow Agent has been advised or was otherwise aware of the likelihood of such loss or damages and regardless of the form of action.

(c) The Escrow Agent may execute any of its powers and perform any of its duties hereunder by or through its attorneys, agents, receivers or employees. The Escrow Agent is entitled to advice of counsel concerning all matters hereunder, and may act on the opinion or advice of counsel, accountants, engineers or surveyors selected in good faith by the Escrow Agent. The Escrow Agent is not responsible for any loss or damage resulting from any action or non-action taken or made in good faith in reliance on any such opinion or advice.

(d) The Escrow Agent shall be entitled to rely upon any order, judgment, certification, demand, notice, instrument or other writing delivered to it hereunder without being required to determine the authenticity or the correctness of any fact stated therein or the propriety or validity of the service thereof. The Escrow Agent may act in reliance upon any instrument or signature reasonably believed by it to be genuine and may assume that the person purporting to give receipt or advice or make any statement or execute any document in connection with the provisions hereof has been duly authorized to do so.

(e) Each of Securityholders Representative, on behalf of the Securityholders, and Parent will indemnify and hold the Escrow Agent and each of its officers, directors, employees and affiliates (the “Indemnified Parties”) harmless from and against any and all claims, suits, liabilities, costs, damages and expenses (including reasonable attorneys’ fees and expenses) suffered or incurred by an Indemnified Party and arising out of or relating to this Escrow Agreement, except any such claims, suits, liabilities, costs, damages or expenses suffered or incurred by an Indemnified Party as a result of the gross negligence or willful misconduct of any Indemnified Party. Parent and the Securityholders Representative, on behalf of the Securityholders, shall each be liable for one-half of the payments owing to the Escrow Agent under this Section 6(e).

7. Term; Termination.

(a) This Escrow Agreement shall terminate on first to occur of (i) the date as of which all Escrow Funds in the Escrow Accounts have been disbursed or released in

accordance with this Escrow Agreement and (ii) the date that is five business days after the date on which the Securityholders Representative and Parent give joint written notice to the Escrow Agent that this Escrow Agreement shall terminate.

(b) The Escrow Agent may resign as escrow agent hereunder upon 30 days’ prior written notice to the Securityholders Representative and Parent. The Securityholders Representative and Parent may at any time, with or without cause, remove the Escrow Agent by giving 10 days’ prior written notice signed by both the Securityholders Representative and Parent to the Escrow Agent. If the Escrow Agent shall resign or be removed, a successor escrow agent, which shall be a bank or trust company having offices in New York, NY and assets in excess of $2 billion, shall be appointed jointly by the Securityholders Representative and Parent and notified to the Escrow Agent by written notice signed by the Securityholders Representative and Parent and delivered to the Escrow Agent and to such successor escrow agent and, thereupon, the resignation or removal of the predecessor Escrow Agent shall become effective and such successor escrow agent, without any further act, deed or conveyance, shall become vested with all right, title and interest in and to all cash and property held hereunder of such predecessor Escrow Agent. No such resignation or removal shall discharge any liability or obligations of the Escrow Agent arising prior to the effective time of such resignation or removal.

(c) All obligations of the Escrow Agent hereunder shall cease and terminate on the effective date of its resignation or removal and its sole responsibility thereafter shall be to hold the Escrow Funds for a period of 30 calendar days following the effective date of resignation or removal, at which time, if a successor escrow agent shall have been appointed and have accepted such appointment in a writing to the Securityholders Representative and Parent, then upon written notice thereof given by the Securityholders Representative and Parent to the resigning or removed Escrow Agent, the resigning or removed Escrow Agent shall deliver the Escrowed Funds to the successor escrow agent. If a successor escrow agent shall not have been appointed within a 30-day period from the Escrow Agent’s resignation or removal, for any reason whatsoever, the resigning or removed Escrow Agent may deliver the Escrow Funds to a court of competent jurisdiction in the county in which the Escrow Funds are then being held and give written notice of the same to the Securityholders Representative and Parent. The Escrow Agent’s sole responsibility after such 30-day notice period expires shall be to hold the Escrow Funds (without any obligation to reinvest the same) and to deliver the same to a designated substitute escrow agent, if any, or in accordance with the directions of a final order or judgment of a court of competent jurisdiction, at which time of delivery Escrow Agent’s obligations hereunder shall cease and terminate.

(d) The resigning Escrow Agent shall be entitled to payment, solely from the Escrow Funds, of any unpaid fees and expenses and to reimbursement for any expenses

incurred in connection with the transfer of the Escrow Funds pursuant to and in accordance with the provisions of this Section 7.

8. Representations and Warranties.

(b) Contemporaneously with the execution and delivery of this Escrow Agreement, each of the Securityholders Representative and Parent shall deliver an incumbency certificate, in form and substance satisfactory to the Escrow Agent, as to the officers authorized to act on its behalf under this Escrow Agreement. The Securityholders Representative and Parent shall update their respective incumbency certificates from time to time to reflect any changes in such authorized officers.

9. Assignment; Resignation of Securityholders Representative. The Escrow Agent acknowledges and agrees that the Securityholders Representative has the right to resign as securityholders representative under and pursuant to the terms of the Merger Agreement at any time. In the event the Securityholders Representative resigns from its role as securityholders representative under the Merger Agreement, the Securityholders Representative shall have the right to assign this Escrow Agreement and its rights and obligations hereunder to the person selected to replace the Securityholders Representative as securityholders representative under and pursuant to the terms of the Merger Agreement without the consent of the Escrow Agent or any other Party; provided that the replacement securityholders representative shall agree to be bound by the terms and conditions of this Escrow Agreement as fully as if it were an original signatory hereto.

11. Notices. All communications and notices permitted or required under this Escrow Agreement shall be in writing and shall be sent: (i) by hand delivery; (ii) by commercial overnight courier; (iii) by certified mail, postage prepaid, return receipt requested; or (iv) by facsimile transmission or electronic mail delivery of a PDF file, to a Party using the following information, or such other information as a Party has given to the other Parties in the manner specified in this Section 11:

If such Securityholder fails to respond and deliver a properly completed and executed Tax Form within 20 days after the Payment Agent’s attempt to contact such Securityholder, the Payment Agent shall, provided the other conditions to payment are satisfied, make payment of the Closing Date Payment and any subsequent Escrow Fund Payments (as defined below) to such Securityholder (and such payments will be subject to applicable withholding as set forth in Section 3.6 below). In cases where the Letter of Transmittal has been improperly completed or executed or where the Shares presented are not in proper form for transfer,

or if some other irregularity exists in connection with their surrender, including any irregularity relating to stop transfer instructions, the Payment Agent will seek instructions from Parent and the Securityholders Representative and will, thereafter, take such actions as are reasonably within its authority under this Agreement to cause such irregularity to be corrected. The Payment Agent is not authorized to waive an irregularity in connection with the surrender of Shares, except following receipt of the prior written approval of an Authorized Representative of Parent and the Securityholders Representative authorizing the Payment Agent to waive such irregularity; provided that the Payment Agent and Parent agree that Parent and the Securityholders Representative waiving such irregularity in accordance with this Agreement shall not cause the Payment Agent to be subjected to any potential liability related thereto. In the absence of such waiver by Parent and the Securityholders Representative, the Payment Agent is authorized not to accept such stock certificates for exchange and will return to the surrendering Stockholder by trackable mail method to such Stockholder’s address as set forth on Schedule A, the Letter of Transmittal, any stock certificates surrendered in connection therewith and any other documents received therewith, together with a written explanation of the reason for the Payment Agent’s determination not to accept the stock certificates for exchange. Parent acknowledges and agrees that Securityholders holding RSUs shall not be required to submit any documentation other than a Surrender Agreement and the applicable Tax Form in order to become an Eligible Securityholder and to receive Escrow Funds Payments hereunder.

3.4 Payments.

(a) Payment of Merger Consideration. Parent hereby directs the Payment Agent, consistent with this Agreement, the Letters of Transmittal and Schedule A (as the same may be amended, modified or revised from time to time in accordance with this Agreement), to mail by first class mail to each Eligible Securityholder holding Shares a check drawn, or remit a bank wire transfer (if applicable), in an amount set forth on Schedule A directly opposite from such Securityholder’s name (each such amount the “Closing Date Payment”) as soon as reasonably practicable (but in all events within two (2) Business Days) following the receipt of (i) a Letter of Transmittal and (ii) stock certificate(s) representing Shares (subject to Section 3.5 below). Wire transfer instructions will be provided for each Securityholder electing a bank wire transfer by direction of the Securityholder in accordance with the Letter of Transmittal, if applicable. Checks shall be made payable to the holder of record of the Shares, or to the person, if any, whose name has been specified in the Letter of Transmittal received by the Payment Agent with respect to payment for such Shares. Parent and the Payment Agent acknowledge and agree that no payment from the Initial Payment Fund will be made to Securityholders in respect of RSUs.

(b) Payment of Escrow Funds. Parent hereby directs the Payment Agent, upon each receipt of Escrow Funds from the Escrow Agent pursuant to the terms of the Indemnity and Adjustment Escrow Agreement or the Securityholders Representative Escrow Agreement, to mail by first class mail to each Eligible Securityholder, a check drawn, or remit a bank wire transfer (if applicable), in an amount equal to such Securityholder’s Percentage Share (as set forth on Schedule A directly opposite from such Securityholder’s name) of such Escrow Funds, subject to any withholding of taxes in accordance with Section 3.6 hereof (each such payment, an “Escrow Funds Payment”) as soon as reasonably practicable following receipt of the Escrow Funds (but in all events within two (2) Business Days). Wire transfer instructions will be provided for each Securityholder electing a bank wire transfer by direction of the Securityholder in accordance with the Letter of Transmittal, if applicable. Checks shall be made payable to the holder of record of the Shares or RSUs, as applicable, or to the person, if any, whose name has been specified in the Letter of Transmittal or Surrender Agreement, as applicable, received by the Payment Agent.

3.5 Lost, Stolen or Destroyed Certificates. If any Stockholder reports to the Payment Agent that such Securityholder’s failure to surrender a certificate representing any Shares is due to the

loss or destruction of such certificate, the Payment Agent shall require such Stockholder to furnish an affidavit of loss and, if requested by the Payment Agent, a $100 payment to the Payment Agent and/or an indemnity bond in the amount of the consideration to be paid to the Stockholder in respect of such lost certificates; provided, however, that in no event shall a Stockholder be required to pay more than 5% of the total amount of the consideration which may be received by it pursuant to the Merger Agreement for the lost, destroyed or stolen Certificates (or such lesser amount as Parent may reasonably agree to) in order to obtain such indemnity bond, and in the event the cost of such indemnity bond would exceed 5%, then the Stockholder shall only be required to purchase an indemnity bond providing the maximum amount of coverage that may be purchased for a price equal to 5% of the total amount of the consideration which may be received by the Stockholder for the lost, destroyed or stolen Certificates. Upon receipt of such affidavit of loss, Parent instructs the Payment Agent to effect payment to the Securityholder as though it had surrendered its stock certificate.

3.6 Tax Reporting and Withholding.

(a) Payments to Securityholders. The Payment Agent will prepare and mail to each Securityholder on behalf of Parent, other than with respect to the RSUs, the appropriate Internal Revenue Service (“IRS”) Form 1099-B or other applicable form for each Securityholder with respect to all payments made (including any withheld amounts treated as made) under this Agreement unless Parent directs otherwise prior to payment to the Securityholder. The Payment Agent will file copies of such Forms 1099-B or other applicable form with the IRS or other taxing authority before the deadline for remittance and information reporting in accordance with the Treasury Regulations. With respect to the holders of RSUs, Parent will, or Parent will cause the Surviving Corporation to, handle or cause to be handled any tax reporting that must be done on IRS Form W-2, 1099 MISC or other applicable forms.

(b) IRS Tax Identification Forms and Withholding. The Payment Agent shall be considered the payor with respect to payments made to the Securityholders other than with respect to RSUs on behalf of Parent pursuant to the terms of this Agreement, including payments of Escrow Funds. Accordingly, the Payment Agent is considered the “withholding agent” for purposes of such payments as that term is defined under the United States Treasury Regulations. The Payment Agent will solicit the Tax Forms as part of the Letter of Transmittal mailing to the Stockholders. The Payment Agent will determine from the materials reviewed pursuant to Section 3.3 whether it has obtained the properly completed and executed Tax Forms from each Securityholder other than with respect to RSUs. The Payment Agent shall remit copies of all Tax Forms received from Securityholders to Parent upon written request from Parent. To the extent the Payment Agent is required to withhold any taxes from payments to a Securityholder other than with respect to RSUs, the Payment Agent shall cause such amounts to be withheld and deposited with the IRS in accordance with United States Treasury Regulations. Such amounts will be withheld only from the Securityholders other than with respect to RSUs with respect to whom the applicable properly completed and executed Tax Forms were not received, was not properly completed, or if such Tax Forms indicate that the Securityholder is not exempt from tax withholding, and the withheld amount shall be treated as having been paid to such Securityholder for purposes of satisfying Parent’s obligation to pay such Securityholder in accordance with the Merger Agreement.

Promptly after the Payment Agent receives Escrow Funds, Parent and the Surviving Corporation (or the designee of either) shall determine the corresponding Employer Tax Amount with respect to Escrow Funds to be distributed to Securityholders surrendering RSUs. Parent or Surviving Corporation shall solicit appropriate tax forms from the holders of RSUs. Notwithstanding the foregoing provisions of this Section 3.6(b), promptly after the determination of the Employer Tax Amount, the Payment Agent shall pay by wire transfer of immediately available funds such Employer Tax Amount to a payroll processor designated in writing by Parent, or such other person that is responsible for the preparation and payment of employment tax returns and remittance of the Employer

Tax Amount with and to the IRS and other applicable taxing authorities, in each case, for remittance to the IRS and other applicable taxing authority in respect of employee employment tax. Parent, Surviving Corporation or such person designated by Parent or Surviving Corporation shall be the “withholding agent” with respect to all payments with respect to the RSUs.

(c) Indemnification. Parent shall indemnify, defend and hold the Payment Agent harmless from and against any tax, late payment, interest, penalty or other cost or expense that may be assessed against the Payment Agent arising out of or in connection with the performance of the Payment Agent’s obligations under the terms of this Section 3.6 unless such tax, late payment, interest, penalty or other expense resulted from the gross negligence or willful misconduct of the Payment Agent or the failure to comply with Section 3.6(b). The indemnification provided by this Section 3.6(c) is in addition to the indemnification provided in Section 5.5 and shall survive the resignation or removal of the Payment Agent and the termination of this Agreement.

3.7 Submission of Stock Certificates by Stockholders Not of Record but Who Have Acquired Their Shares in Due Course. Certain stock certificates representing Shares may be tendered by Securityholders who are holders in due course but are not registered holders. Upon submission of such a certificate duly endorsed or with assignments duly executed by the registered holder of the Shares represented thereby (or by such registered holder’s duly appointed agent, attorney, executor, administrator, guardian or other fiduciary), together with the requisite medallion guarantee of signature (and evidence of authority if appropriate), and in accordance with the Securities Transfer Association guidelines, if such certificate is accompanied by a duly completed and executed Letter of Transmittal, the Payment Agent will be entitled to treat such certificate as if surrendered by the registered holder thereof, and make the requisite payment to the holder in due course.

3.8 Cancellation of Surrendered Stock Certificates. At the time of the payments pursuant to Section 3.4(a) above, the Payment Agent will cancel each stock certificate surrendered in exchange for such payment. For the term of this Agreement the Payment Agent will maintain on a continuing basis a list of Eligible Securityholders, and at the request of Parent or the Securityholders Representative, the Payment Agent will inform it as to which Securityholders are Eligible Securityholders. The Payment Agent will also make available to Parent such other information as it may have in its possession and as Parent may reasonably request from time to time. After the Paying Agent has paid and canceled the stock certificates surrendered, such canceled certificates shall be returned to the Parent at the address provided in this Agreement unless otherwise notified in writing by the Parent of an alternate address.

3.9 Database of Electronic Records. Subject to applicable law and regulation and this Section 3.9, the Payment Agent shall maintain (a) electronic records in a retrievable database or (b) physical records of all received: (i) stock certificates, (ii) Letters of Transmittal, and (iii) Tax Forms, and the Payment Agent shall provide a copy of such records to Parent and the Securityholders Representative upon written request (at the requesting party’s expense). The Payment Agent shall also maintain such electronic records or physical records for the time period required by applicable law and regulation.

3.10 Mailing of Second Letter of Transmittal and Unexchanged Securityholder Program. No later than four months after the Effective Time or upon the earlier request in writing of Parent, the Payment Agent shall send a second Letter of Transmittal to any Securityholder that is not an Eligible Securityholder, or that has been otherwise identified by Parent in such request. From time to time upon the request in writing of Parent and at Parent’s expense, the Payment Agent shall utilize the services of an unexchanged stockholder search company (a “Search Company”) for the purpose of locating Securityholders that have not surrendered Shares or submitted Letters of Transmittal and assisting them in doing so. If an additional agreement with a Search Company needs to be signed in order to fulfill the

request of Parent, such agreement shall be on terms and conditions reasonably acceptable to the Payment Agent and Parent.

ARTICLE 4

UNCLAIMED PROPERTY

4.1 Unclaimed Property Administration. Subject to applicable unclaimed property laws, the Payment Agent will initiate unclaimed property reporting services for unclaimed Shares and cash distributions, which may be deemed abandoned or otherwise subject to applicable unclaimed property law or regulation. Such services may include preparation of unclaimed property reports, delivery of abandoned property to various states, completion of required due diligence notifications, responses to inquiries from owners, and such other services as may reasonably be necessary to comply with applicable unclaimed property laws or regulations.

4.2 Information about Unclaimed Property. Parent shall assist the Payment Agent and provide such cooperation as may reasonably be necessary in the performance of the services hereunder.

4.3 Inquiries about Unclaimed Property. The Payment Agent shall assist Parent or the Surviving Corporation in responding to inquiries from administrators of state unclaimed property laws or regulations regarding reports filed on their behalf or in response to requests to confirm the name of a reclaiming owner. The Payment Agent shall exercise reasonable efforts to obtain release agreements from the various states offering such release agreements with respect to reports and abandoned property delivered to them and indemnification agreements from those states willing to provide them.

4.4 Remittance of Unclaimed Property. The Payment Agent or its duly appointed agent shall timely remit unclaimed funds to the appropriate state or jurisdiction, as provided for under applicable unclaimed property law or regulation. The Payment Agent shall provide such reports regarding unclaimed property services hereunder as Parent may reasonably request from time to time.

4.5 Lost Security Holder Search Services. Pursuant to Securities and Exchange Commission (“SEC”) rules (See SEC Rule 240.17 Ad-17, as amended), the Payment Agent is required to provide the following services regarding lost security holder accounts, which together constitute Standard Search Services: (a) conduct a national database search between three and twelve months after a lost security holder account is identified; (b) if the first national database search is not successful in locating the holder, conduct a second search between six and twelve months later; and (c) report to the SEC in required filings, information about the age of lost security holder accounts and amounts escheated to the various states. Exceptions to the SEC search requirements include deceased security holders, security holders that are not natural persons (e.g., corporations, partnerships), and cases where the value of all amounts due to the security holder are less than $25.

ARTICLE 5

RIGHTS OF THE PAYMENT AGENT

5.1 Advice of Counsel.

(a) Advice in Case of Defective Submission. The Payment Agent is authorized to cooperate with and furnish information to Parent and the Securityholders Representative and shall seek

(b) Advice in Other Cases. Notwithstanding the provisions of Section 5.l(a) above, the Payment Agent may, when the Payment Agent deems it desirable and after prior consultation with Parent, seek advice of the Payment Agent’s own counsel in connection with the Payment Agent’s services as Payment Agent hereunder and the Payment Agent shall be entitled in to rely in good faith upon any such advice received in writing and to be compensated for the fees and expenses of such counsel as provided in Section 5.2 below.

5.2 Fees and Expenses. The Payment Agent shall receive, from Parent, as compensation for the performance of its duties as such hereunder, the fees set forth on Schedule B.

Such costs may include, but are not limited to, postage mail insurance, stationery and supplies, checks, envelopes, paper stock and reasonable fees and expenses of counsel.

The Payment Agent shall have no responsibility or liability for the accuracy or inaccuracy of such Certificates and Instructions.

5.5 Standard of Care; Indemnification.

The indemnities provided by this Section 5.5 shall survive the resignation or discharge of the Payment Agent or the termination of this Agreement. Anything in this Agreement to the contrary notwithstanding, in no event shall the Payment Agent or Parent be liable under or in connection with this Agreement for indirect, special, incidental, punitive or consequential losses or damages of any kind whatsoever, including but not limited to lost profits, whether or not foreseeable, even if the Payment Agent or Parent has been advised of the possibility thereof and regardless of the form of action in which such damages are sought.

5.6 Term. Parent and the Payment Agent agree that this Agreement shall terminate upon the later of: (a) written notice from the Securityholders Representative, Parent or the Escrow Agent that all funds held in escrow pursuant to the Indemnity and Adjustment Escrow Agreement have been disbursed or (b) upon completion of all unclaimed property reporting and escheatment obligations arising in connection with the Merger and the duties of the Payment Agent pursuant to this Agreement. If, upon termination of this Agreement, any Shares remain unexchanged or other payments remain unpaid and moneys and/or securities on deposit hereunder are not escheatable in accordance with unclaimed property laws and regulations, any remaining moneys, securities and property shall be delivered by the Payment Agent to Parent. Thereafter, Parent shall be responsible for compliance with unclaimed property obligations.

written notice to the Payment Agent and Parent or the Securityholders Representative, as applicable. Any inconsistency between this Agreement, on the one hand, and the Merger Agreement or the Letter of Transmittal, on the other hand, shall be resolved in favor of the Merger Agreement or the Letter of Transmittal, as applicable; provided that (a) the Payment Agent is not a party to the Merger Agreement and is not subject to its terms, and (b) the rights and obligations of the Payment Agent shall be governed solely by the provisions of this Agreement, without reference to the Merger Agreement. In the absence of written notice from Parent to the effect that an inconsistency exists between the Merger Agreement or Letter of Transmittal, on the one hand, and this Agreement, on the other hand, the Payment Agent shall be entitled to assume that no such inconsistency exists and shall not have any duty to inquire as to the existence of any such inconsistency.

5.9 Counterparts and Severability. This Agreement may be executed in one or more counterparts, including by facsimile or electronic mail delivery of a pdf file, each of which shall be deemed an original and all of which together shall constitute one instrument. If any provision of this Agreement shall be held illegal, invalid or unenforceable by any court, this Agreement shall be construed and enforced as if such provision had not been contained herein and shall be deemed binding and enforceable to the full extent permitted by applicable law.

5.10 Law; Waiver of Jury Trial. This Agreement shall be governed in all respects, including validity, interpretation and effect, by the non-exclusive jurisdiction and laws of the State of Delaware. EACH OF THE PARTIES HERETO EXPRESSLY WAIVES THE RIGHT TO TRIAL BY JURY IN RESOLVING ANY CLAIM OR COUNTERCLAIM RELATING TO OR ARISING OUT OF THIS AGREEMENT.

5.11 Assignment; Resignation of Securityholders Representative.

(a) This Agreement may not be assigned by any party hereto without prior written consent of the other parties hereto; provided that (i) the Securityholders Representative may assign its rights under this Agreement to any successor Securityholders Representative elected or selected to replace it in accordance with the terms of the Merger Agreement without the consent of any party hereto, so long as the replacement Securityholders representative shall agree to be bound by the terms and conditions of this Agreement as fully as if it were an original signatory hereto, and (ii) Parent may assign any or all of its rights under this Agreement to any one or more Securityholders without the consent of any party hereto.

(b) Notwithstanding anything to the contrary in this Agreement, if at any time the Securityholders Representative shall have resigned and no replacement Securityholders Representative shall have been designated in accordance with the terms of the Merger Agreement:

(i) any requirement in this Agreement to deliver notice to the Securityholders Representative shall be deemed to be satisfied upon the delivery of notice to each of the Securityholders at the applicable addresses set forth on Schedule A; and

5.12 Payment Matter. In the event that Payment Agent makes any payment to any party pursuant to this Agreement and for any reason such payment (or any portion thereof) is required to be returned to any account or fund hereunder or to another party or is subsequently invalidated, declared to be fraudulent or preferential, set aside and/or required to be repaid to a receiver, trustee or other party under any bankruptcy or insolvency law, other federal or state law, common law or equitable doctrine, then the recipient shall repay to Payment Agent upon written request the amount so paid to it. [NTD: Is this a provision required by the Payment Agent?]

5.13 Compliance with Orders. Payment Agent shall comply with judgments or orders issued or process entered by any court with respect to the funds held by it hereunder, including, without limitation, any attachment, levy or garnishment, without any obligation to determine such court’s jurisdiction in the matter and in accordance with its normal business practices.

ARTICLE 6

Each of the Payment Agent, the Securityholders Representative and Parent acknowledges that during the term of this Agreement, the parties hereto may make confidential data available to each other or may otherwise obtain proprietary or confidential information regarding Parent, the Company or the Surviving Corporation, the Securityholders and the Payment Agent (collectively, hereinafter “Confidential Data”). Confidential Data includes all information not publicly available and includes, but is not limited to, (a) data or information which identifies past, current or potential customers, stockholders, business practices, financial results, research, development, systems and plans, (b) any information and material identified by the Company, the Surviving Corporation, the Payment Agent or Parent as “Proprietary” or “Confidential”; (c) data the Payment Agent furnishes to Parent from the Payment Agent’s database, and/or (d) data received from the Company, the Surviving

6.3 Security Measures.

Without limiting the foregoing, the Payment Agent further agrees, subject to applicable law and regulations, that: (i) Confidential Data shall not be distributed, disclosed, or conveyed to any third party except by prior written approval of Parent; (ii) no copies or reproductions shall be made of any Confidential Data, except as needed to provide the services described in this Agreement; and (iii) the Payment Agent shall not use any Confidential Data for its own benefit or for the benefit of any third party.

IMPORTANT TAX INFORMATION

Purpose of Substitute Form W-9

If you are a U.S. Person (defined below), to prevent backup withholding on any payments that may be made to you, you are required to notify the Paying Agent of your correct taxpayer identification number. To do this, you should complete the substitute Form W-9 provided above by filling in your name and address in the space provided, filling in your taxpayer identification number in Part I of the Form (or writing “Applied For” if you are awaiting a taxpayer identification number and completing the box entitled “CERTIFICATE OF AWAITING TAXPAYER IDENTIFICATION NUMBER”), crossing out Item 2 of the certification where and if applicable, indicating your exempt status, if applicable, by checking the box in Part II, and signing and dating the Form at the bottom. By doing so you will be certifying that the taxpayer identification number provided on Substitute Form W-9 is correct (or that you are awaiting a taxpayer identification number) and that (1) you are exempt from backup withholding, (2) you have not been notified by the Internal Revenue Service that you are subject to backup withholding as a result of failure to report all interest or dividends or (3) you have been notified by the Internal Revenue Service that you are no longer subject to backup withholding. See the enclosed “Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9” for additional instructions. For purposes of the substitute Form W-9, a U.S. Person is an individual who is a U.S. citizen or U.S. resident alien, a partnership, corporation, company, or association created or organized in the United States or under the laws of the United States, or any political subdivision thereof, an estate (other than a foreign estate) or a domestic trust.

If you are not a U.S. Person, you should not complete a substitute Form W-9. Instead, to avoid backup withholding, you should complete an IRS Form W-8BEN (or other appropriate type of IRS Form W-8). In the case of Non-U.S. Person for which IRS Form W-8BEN is the appropriate form, IRS Form W-8BEN requires a Non-U.S. Person to provide such Non-U.S. Person’s name and address, along with certain other information, and to certify, under penalties of perjury, that such Non-U.S. Person is not a U.S. Person. Non-U.S. Persons may obtain an IRS Form W-8BEN and instructions (or other appropriate IRS Form W-8) from the IRS’s website (http://www.irs.gov).

What Number to Set Forth

You should provide the social security number (if an individual) or employer identification number of the record owner of the Shares surrendered hereby in the space provided on Part I of the Substitute Form W-9. If the Shares are in more than one name or are not in the name of the actual owner, consult the enclosed “Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9” for additional guidelines on which number to report.

Failure to include a properly completed substitute Form W-9 or IRS Form W-8BEN (or other appropriate IRS Form W-8) may result in the application of U.S. backup withholding.

For this type of account:			Give the SOCIAL SECURITY number of:
1.	An individual’s account		The individual

2.	Two or more individuals (joint account)		The actual owner of the account or, if combined funds, the first individual on the account (1)

3.	Custodian account of a minor (Uniform Gift to Minors Act)		The minor (2)

4.	a. b.	The usual revocable savings trust account (grantor is also trustee) So-called trust account that is not a legal or valid trust under State law	The grantor-trustee (1) The actual owner (1)

5.	Sole proprietorship account or single-owner LLC		The owner (3)

For this type of account:		Give the EMPLOYER IDENTIFICATION number of:
6.	A valid trust, estate, or pension trust	The legal entity (4)

7.	Corporation or LLC electing corporate status on Form 8832 or Form 2553	The corporation

11.	Account with the Department of Agriculture in the name of a public entity (such as a State or local government, school district, or prison) that receives agricultural program payments	The public entity

(1) List first and circle the name of the person whose number you furnish. If only one person on a joint account has a social security number, that person’s number must be furnished.

(2) Circle the minor’s name and furnish the minor’s social security number.

(3) You must show your individual name. You may also enter your business or “doing business as” name. You may use either your social security number or, if you have one, your employer identification number.

(4) List first and circle the name of the legal trust, estate or pension trust. Do not furnish the identifying number of the personal representative or trustee unless the legal entity itself is not designated in the account title.

Obtaining a Number

If you do not have a taxpayer identification number, apply for one immediately. To apply for an SSN, obtain Form SS-5, Application for a Social Security Card, from your local Social Security Administration office or get this form online at www.socialsecurity.gov/online/ss-5.pdf. You may also get this form by calling 1-800-772-1213.

You can apply for an EIN online by accessing the IRS website at www.irs.gov/businesses/ and clicking on Employer ID Numbers under Starting a Business. You can get Forms W-7 and SS-4 from the IRS by visiting www.irs.gov or by calling 1-800-TAX-FORM (1-800-829-3676).

To complete the Substitute Form W-9 if you do not have a TIN, write “Applied For” in the space provided for the TIN, complete the Certificate of Awaiting Taxpayer Identification Number, sign and date the form and return it to the Paying Agent. For interest and dividend payments, and certain payments made with respect to readily tradable instruments, generally you will have 60 days to get a TIN and give it to the Paying Agent before you are subject to backup withholding on payments. The 60 day rule does not apply to other types of payments. You will be subject to backup withholding on all such payments until provide your TIN to the Paying Agent.

Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the Merger Agreement, a copy of which has been provided to the RSU Holder.

2. The RSU Holder further agrees that any restricted share unit agreements previously entered into between the Company and the RSU Holder (the “RSU Award Agreements”) shall be automatically terminated as of the Effective Time with no further obligations of the Company thereunder except as provided herein and in the Merger Agreement. The RSU Holder further acknowledges that the RSU Holder is aware of the terms of the Merger and does hereby waive all requirements under the Equity Compensation Plan (as defined in Section B.1 below) and any RSU Award Agreements heretofore entered into by the RSU Holder in respect of notice to be given by the Company in connection with the Merger or in respect of any action otherwise required thereunder by the Company, and by execution of this Surrender Agreement hereby waives and relinquishes any and all right to receive consideration for the RSUs other than as provided herein and in the Merger Agreement.

The amounts deposited with the Escrow Agent, together with any interest, investment income or other proceeds applicable thereto, shall be held by the Escrow Agent, subject to the terms and conditions of the Escrow Agreement and the Securityholders Representative Escrow Agreement. The undersigned RSU Holder will be entitled to receive any portion of the Escrow Amount that is distributed to the Stockholders and the holders of RSUs, if any, in proportion to the undersigned RSU Holders’s percentage share of the Fully Diluted Common Stock, less applicable Tax Obligations. The undersigned RSU Holder acknowledges that indemnification claims and other claims made on the Escrow Amount may delay or preclude the release of some or all of the Escrow Amount to the undersigned RSU Holder.

3. The RSU Holder acknowledges that all payments to be made pursuant to this Surrender Agreement and the Merger Agreement will be made as follows:

(a) the Closing Common Share Price, less applicable Tax Obligations, will be paid by the Company or the Surviving Corporation (or, if requested by the

Surviving Corporation, the Paying Agent) on or immediately following the Closing Date (or, if later, upon delivery of a duly executed Surrender Agreement to the Surviving Corporation); and

(b) any remaining portion of the Common Share Price that may become payable to the Securityholders pursuant to the terms of the Merger Agreement, less applicable Tax Obligations, will be paid by the Surviving Corporation immediately following the Surviving Corporation’s receipt of the funds from the Paying Agent pursuant to the Paying Agent Agreement or, at the request of the Surviving Corporation, by the Paying Agent.

4. Payments to be made by the Paying Agent, the Company or the Surviving Corporation will be made by delivery of a check to the RSU Holder at the address set forth below, or, if the RSU Holder is employed by the Company or the Surviving Corporation at the time of such payment and the Company or the Surviving Corporation makes the payment directly, in accordance with payroll practices, including by automatic deposit.

The IRS may also disclose this information to other countries under a tax treaty, to federal and state agencies to enforce federal non-tax criminal laws, or to federal law enforcement and intelligence agencies to combat terrorism. Payers must be given the numbers whether or not recipients are required to file tax returns. Payers must generally withhold 28% of taxable interest, dividends and certain other payments to a payee who does not furnish a taxpayer identification number to a payer. Certain penalties may also apply.

Penalties

(1) Penalty for Failure to Furnish Taxpayer Identification Number.—If you fail to furnish your taxpayer identification number to a payer, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect.

(2) Civil Penalty for False Information With Respect to Withholding.—If you make a false statement with no reasonable basis which results in no imposition of backup withholding, you are subject to a penalty of $500.

(3) Criminal Penalty for Falsifying Information.—Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.
