7.5All payments under this Agreement shall be made subject to applicable tax withholding, and the Company shall withhold from any payments under this Agreement all federal, state and local taxes as the Company is required to withhold pursuant to any law or governmental rule or regulation. The Employee shall bear all expense of, and be solely

responsible for, all federal, state and local taxes due with respect to any payment received under this Agreement.

7.6In the event of a change in ownership or control of the Company under Section 280G of the Code, if it shall be determined that any payment or distribution in the nature of compensation (within the meaning of section 280G(b)(2) of the Code) to or for the benefit of the Employee, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise (a “Payment”), would constitute an “excess parachute payment” within the meaning of Section 280G of the Code, the aggregate present value of the Payments shall be reduced (but not below zero) to the Reduced Amount (defined below) if and only if the Accounting Firm (described below) determines that the reduction will provide the Employee with a greater net after-tax benefit than would no reduction. No reduction shall be made unless the reduction would provide the Employee with a greater net after-tax benefit. The determinations under this Section 7.6 shall be made as follows:

(A)The “Reduced Amount” shall be an amount expressed in present value which maximizes the aggregate present value of Payments under this Agreement without causing any Payment under this Agreement to be subject to the Excise Tax (defined below), determined in accordance with Section 280G(d)(4) of the Code. The term “Excise Tax” means the excise tax imposed under Section 4999 of the Code, together with any interest or penalties imposed with respect to such excise tax.

(B)Payments under this Agreement shall be reduced on a nondiscretionary basis in such a way as to minimize the reduction in the economic value deliverable to the Employee. Where more than one Payment has the same value for this purpose and they are payable at different times, they will be reduced on a pro rata basis. Only amounts payable under this Agreement shall be reduced pursuant to this Section 7.6.

(C)All determinations to be made under this Section 7.6 shall be made by an independent certified public accounting firm selected by the Company and agreed to by the Employee immediately prior to the change-in-ownership or -control transaction (the “Accounting Firm”). The Accounting Firm shall provide its determinations and any supporting calculations both to the Company and the Employee within ten (10) days of the transaction. Any such determination by the Accounting Firm shall be binding upon the Company and the Employee. All of the fees and expenses of the Accounting Firm in performing the determinations referred to in this Section 7.6 shall be borne solely by the Company.

7.7The Employee’s or the Company’s failure to insist upon strict compliance with any provision of this Agreement or the failure to assert any right the Employee or the Company may have hereunder shall not be deemed to be a waiver of such provision or right or any other provision or right of this Agreement.

8.ARBITRATION

(A)Except as provided herein, any and all disputes that arise out of or relate to the terms of this Agreement shall be resolved through final and binding arbitration. SUCH ARBITRATION SHALL BE IN LIEU OF ANY TRIAL BEFORE A JUDGE AND/OR JURY, AND THE EXECUTIVE AND THE COMPANY EXPRESSLY

WAIVE ALL RIGHTS TO HAVE SUCH DISPUTES RESOLVED VIA TRIAL BEFORE A JUDGE AND/OR JURY. Such disputes shall include, without limitation, claims for breach of contract or of the covenant of good faith and fair dealing, claims of discrimination, and claims under any federal, state or local law or regulation now in existence or hereinafter enacted and as amended from time to time concerning in any way the Employee’s employment with the Company or its termination. The only claims not covered by this requirement to arbitrate disputes, which shall instead be resolved pursuant to applicable law in a court of competent jurisdiction based in Massachusetts, are: (i) claims for benefits under the unemployment insurance benefits; (ii) claims for workers’ compensation benefits under any of the Company’s workers’ compensation insurance policy or fund; (iii) claims under the National Labor Relations Act; (iv) claims brought by the Company for alleged violations of Section 6 of this Agreement; and (v) claims that may not be arbitrated as a matter of law.

(B)Arbitration will be conducted by and before JAMS in Boston, Massachusetts in accordance with the JAMS Employment Arbitration Rules and Procedures (the “JAMS Rules”). To the extent that anything in this arbitration section conflicts with any arbitration procedures required by applicable law, the arbitration procedures required by applicable law shall govern.

(C)During the course of arbitration, the Company will bear the cost of the arbitrator’s fee. The arbitrator will not have authority to award attorneys’ fees unless a statute or contract at issue in the dispute authorizes the award of attorneys’ fees to the prevailing party. In such case, the arbitrator shall have the authority to make an award of attorneys’ fees as required or permitted by the applicable statute or contract.

(D)The arbitrator shall issue a written award that sets forth the essential findings of fact and conclusions of law on which the award is based. The arbitrator shall have the authority to award any relief authorized by law in connection with the asserted claims or disputes. The arbitrator’s award shall be subject to correction, confirmation, or vacation, as provided by applicable law setting forth the standard of judicial review of arbitration awards. Judgment upon the arbitrator’s award may be entered in any court having jurisdiction thereof.

9.SECTION 409A COMPLIANCE

(A)General. It is intended that compensation paid or delivered to the Employee pursuant to this Agreement is either paid in compliance with, or is exempt from, Section 409A of the Code and the regulations promulgated thereunder (“Section 409A”). If the Employee notifies the Company (with specificity as to the reason therefor) that he believes that any provision of this Agreement (or of any award of compensation, including equity compensation or benefits) would cause him to incur any additional tax or interest under Section 409A and the Company concurs with such belief or the Company independently makes such determination, the Company shall, after consultation with the Employee, to the extent legally permitted and to the extent it is possible to timely reform the provision to avoid taxation under Section 409A, reform such provision to attempt to comply with Section 409A through good faith modifications to the minimum extent reasonably appropriate to conform with Section 409A. To the extent that any provision

hereof is modified in order to comply with or be exempt from Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and economic benefit to both the Employee and the Company of the applicable provision without violating the provisions of Section 409A but in any case Employee hereby agrees that all personal income taxes on her compensation under this Agreement and all penalties and interest with respect to such personal income taxes, if any, are her own responsibility. In no event shall the Company have any liability relating to the failure or alleged failure of any payment or benefit under this Agreement to comply with, or be exempt from, the requirements of Section 409A, or any similar Treasury regulations or IRS rules or regulations that replace or supersede Treasury Regulation Section 1.409A after the Effective Date and that relate to the same or similar subject matter as Treasury Regulation Section 1.409A.

(B)Amounts Payable On Account of Termination: To the extent necessary to comply with Section 409A, for the purposes of determining when amounts subject to Section 409A that are payable upon Employee’s termination of employment under this Agreement will be paid, “termination of employment” or words of similar import, as used in this Agreement, shall be construed as the date that Employee first incurs a “separation from service” within the meaning of Section 409A.

(C)Reimbursement: Any taxable reimbursement of business or other expenses as specified under this Agreement shall be subject to the following conditions: (A) the expenses eligible for reimbursement in one taxable year shall not affect the expenses eligible for reimbursement in any other taxable year; (B) the reimbursement of an eligible expense shall be made no later than the end of the year after the year in which such expense was incurred; (C) the right to reimbursement shall not be subject to liquidation or exchange for another benefit; and (D) in accordance with the policies, practices and procedures of the Company.

(D)Specified Employees: If the Employee is deemed on the date of termination to be a “specified employee” within the meaning of that term under Section 409A(a)(2)(B) of the Code, then with regard to any payment that is considered deferred compensation subject to Section 409A payable on account of a “separation from service,” such payment or benefit shall be made, or provided at the date which is the earlier of (i) the expiration of the six (6)-month period measured from the date of such “separation from service”, and (ii) the date of the Employee’s death (the “Delay Period”). Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this section (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or reimbursed to the Employee in a lump sum, with interest thereon calculated at the long-term applicable federal rate (annual compounding) under Section 1274(d) of the Code in effect on the date of termination of employment, and any remaining payments and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein.

(E)Interpretative Rules: In applying Section 409A to amounts paid pursuant to this Agreement, any right to a series of installment payments under this Agreement shall be treated as a right to a series of separate payments.
