Regulations and guidance issued or promulgated under such section (collectively, “ Section 409A ”), the parties intend that the Payments set forth in Sections 3(a)(i) and (ii) shall be treated as exempt from Section 409A under the “short-term deferral” and/or “involuntary separation pay” exemptions and that such payments therefore shall not be subject to the required six-month delay that would apply if such payments constituted “non-qualified deferred compensation” under Section 409A.

           (b) Separate Payments . It is intended that each installment of the payments and benefits provided under Section 3 shall be treated as a separate payment for purposes of Section 409A.

           (c) Separation from Service . For purposes of this Agreement, “ Separation from Service ” shall mean Executive’s “separation from service” from the Company, within the meaning of Section 409A(a)(2)(A)(i) of the Code and Treasury Regulation Section 1.409A-1(h), including the applicable “default” provisions thereunder. Notwithstanding any other provision of this Agreement, including, without limitation, Section 2 , it is the intention of the parties that Executive shall incur a Separation from Service as of the Retirement Date, and this Agreement shall be construed, interpreted and implemented in accordance with such intention.

     6.  Existing Agreements . The terms and conditions of Section 4.3 of the Severance Agreement shall survive the execution of this Agreement and shall apply to any payments or benefits under this Agreement as if set forth in full herein. The Employee Nondisclosure and Development Agreement by and between the Company and Executive shall remain in full force and effect following the Retirement Date, subject to Section 18 . Executive hereby waives any and all rights under the Severance Agreement regarding the receipt of a Notice of Termination (as defined in the Severance Agreement) in connection with the matters described herein.

     7.  Return of Company Property . On the Retirement Date, Executive shall return any property of the Company (including, without limitation, proprietary information or intellectual property) that is within Executive’s custody or control, except to the extent such property is reasonably necessary for Executive to perform the Board Services or Advisory Services, as determined by the Company. Executive shall return any Company property retained by Executive as provided in the preceding sentence upon the expiration of (i) the Board Continuation Period if such property is retained in connection with the performance of Board Services and (ii) the Service Continuation Period if such property is retained in connection with the performance of Advisory Services.

     8.  Non-Competition; Non-Solicitation; Non-Disparagement .

          (a) Executive shall not, at any time during the Restriction Period (as defined below), directly or indirectly engage in the business of, have any equity interest in or manage or operate any person, firm, corporation, partnership or other entity or business (whether as director, officer, employee, agent, representative, partner, security holder, consultant, proprietor, joint venturer or otherwise) that engages in any business which competes with any portion of the Business (as defined below) of the Company anywhere in the Restricted Area (as defined below). Nothing herein shall prohibit Executive from being a passive owner of not more than 1% of the outstanding equity interest in any entity that is publicly traded, so long as Executive

has no active participation in the business of such entity.

          (b) Executive shall not, at any time during the Restriction Period, directly or indirectly, recruit or otherwise solicit or induce any employee, customer, subscriber or supplier of the Company or any prospective employee, customer, subscriber or supplier of the Company (i) to terminate its employment or arrangement with the Company, or (ii) to otherwise change its relationship with the Company. In addition, Executive shall not, at any time during the Restriction Period, directly or indirectly, either for Executive or for any other person or entity employ such individual during his or her employment with the Company and for a period of six months after such individual terminates his or her employment with the Company.

          (c) Executive agrees to refrain from disparaging the Company and its affiliates, including, without limitation, any of their respective products, services, technologies or practices, or any of their respective directors, officers, employees, agents, representatives or stockholders, either orally or in writing. The Company agrees to refrain, and use commercially reasonable efforts to cause its directors and officers to refrain, from disparaging Executive, either orally or in writing. Nothing in this Section 8(c) shall preclude either party from making truthful statements that are reasonably necessary to comply with applicable law, regulation or legal process.

          (d) Executive acknowledges that the restrictions contained in this Section 8 (i) are in consideration for the rights provided to Executive as set forth in this Agreement and the Company’s past and future provision of confidential information to Executive, and (ii) represent a fair balance of the Company’s rights to protect its Business and Executive’s right to pursue employment. In the event the terms of this Section 8 shall be determined by any court of competent jurisdiction to be unenforceable by reason of its extending for too great a period of time or over too great a geographical area or by reason of its being too extensive in any other respect, it will be interpreted to extend only over the maximum period of time for which it may be enforceable, over the maximum geographical area as to which it may be enforceable, or to the maximum extent in all other respects as to which it may be enforceable, all as determined by such court in such action.

          (e) As used in this Section 8 , (i) the term “ Company ” shall include the Company and its direct and indirect parents and subsidiaries, (ii) the term “ Business ” shall mean the Business of the Company or its subsidiaries or affiliates and any business that is competitive with the business, work or projects of the Company or its subsidiaries or affiliates, as such business, work or projects may have been conducted or contemplated during (A) the term of Executive’s employment with the Company or (B) the Service Continuation Period; (iii) the term “ Restricted Area ” shall mean anywhere in the world and (iv) the term “ Restriction Period ” shall mean the period beginning on the Retirement Date and ending on the third anniversary of the Retirement Date.

     9.  Injunctive Relief . It is recognized and acknowledged by Executive that a breach of the covenants contained in Section 8 will cause irreparable damage to the Company and its goodwill, the exact amount of which will be difficult or impossible to ascertain, and that the remedies at law for any such breach will be inadequate. Accordingly, Executive agrees that in the event of a breach of any of the covenants contained in Section 8 , in addition to any other

remedy which may be available at law or in equity, the Company will be entitled to specific performance and injunctive relief.

     10.  General Release and Waiver .

           (a) Release . In consideration of the Payments, Executive, on behalf of himself and his representatives, agents, estate, heirs, successors and assigns, hereby irrevocably and unconditionally releases, remises and discharges the Company, its officers, directors, stockholders, affiliates (within the meaning of the Securities Act of 1933), attorneys, agents and employees, and their respective predecessors, successors and assigns (collectively, the “ Company Releasees ”), from any and all actions or causes of action, suits, claims, complaints, liabilities, contracts, torts, debts, damages, controversies, rights and demands, whether existing or contingent, known or unknown, arising up to and through the later of the Retirement Date and the Effective Date out of Executive’s employment, or the termination of Executive’s employment, with the Company, including, but not limited to, all employment discrimination claims under the Age Discrimination in Employment Act, 29 U.S.C. §621 et seq., Title VII of the Civil Rights Act of 1964, 42 U.S.C. § 2000e et seq., the Americans With Disabilities Act of 1990, 42 U.S.C. § 12101 et seq., the Family and Medical Leave Act, 29 U.S.C. § 2601 et seq., the Worker Adjustment and Retraining Notification Act, 29 U.S.C. § 2101 et seq., the Massachusetts Fair Employment Practices Act, M.G.L. c.151B, § 1 et seq., the Massachusetts Civil Rights Act, M.G.L. c.12, §§ 11H and 11I, the Massachusetts Equal Rights Act, M.G.L. c.93, § 102 and M.G.L. c.214, § 1C, the Massachusetts Labor and Industries Act, M.G.L. c.149, § 1 et seq., and the Massachusetts Privacy Act, M.G.L. c.214, § 1B, all as amended, and all claims arising out of the Fair Credit Reporting Act, 15 U.S.C. § 1681 et seq. and the Employee Retirement Income Security Act of 1974, 29 U.S.C. § 1001 et seq., all as amended; and all claims to any non-vested ownership interest in the Company, contractual or otherwise, including, but not limited to, claims to stock or stock options. Notwithstanding the foregoing, (i) nothing in this release prevents Executive from filing, cooperating with, or participating in any proceeding before the U.S. Equal Employment Opportunity Commission or a state Fair Employment Practices Agency (except that Executive acknowledges that he may not recover any monetary benefits in connection with any such claim, charge or proceeding), (ii) this release does not extend to any rights Executive has that arise after the later of the Retirement Date or the Effective Date or to any rights to payments under and in accordance with the terms of this Agreement and (iii) this release does not extend to any rights Executive may have under the Company’s directors’ and officers’ liability insurance policy or to indemnification as an officer or director of the Company under the provisions of the Company’s by-laws or applicable law.

           (b) Bring Down Release . As a condition to continuing to receive the Payments following the date on which the Service Continuation Period expires, the Executive shall execute and deliver to the Company a release in the form attached hereto as Exhibit A (the “ Bring Down Release ”) on the date upon which the Service Continuation Period expires or Executive will forfeit all remaining Payments.

     11.  Covenant Not to Sue . Executive agrees that he will never sue or file a lawsuit against any Company Releasee including, without limitation, any lawsuit concerning or in any way related to his employment, the termination of that employment, the compensation or benefits payable in connection with his employment, or any other interaction with or matter

pertaining to the Company Releasees, and that no such suit is currently pending. Should Executive violate any aspect of this Section 11 , Executive agrees that any suit shall be null and void. Executive also agrees that if a claim or charge of any kind should be raised, brought, or filed in his name or on his behalf, Executive waives any right to, and agrees not to benefit from or take, any resulting award. This Agreement, including, without limitation, this Section 11 , shall not operate to waive or bar any claim which by express and unequivocal terms of law may not under any circumstances be waived or barred.

     12.  No Other Payments . Executive understands and agrees that the Company shall make any no other payments to Executive and shall have no other obligations to Executive, except as described in this Agreement and that, except as otherwise set forth in this Agreement, all payments or benefits which are provided to Executive by the Company shall terminate on the Retirement Date. Without limiting the generality of the foregoing, Executive acknowledges and agrees that Executive shall not be entitled to any bonus in respect of the Company’s 2010 or 2011 fiscal year or any fiscal year during the Service Continuation Period.

     13.  Taxes . To the extent any taxes may be due on the payments to Executive provided in this Agreement beyond any withheld by the Company, Executive agrees to pay them himself. Executive further agrees to provide any and all information pertaining to Executive upon request as reasonably necessary for the Company and other entities released herein to comply with applicable tax laws.

     14.  Severability . Except as otherwise specified below, should any portion of this Agreement (including, without limitation, Section 8 ) be found void or unenforceable for any reason by a court of competent jurisdiction, the court should attempt to limit or otherwise modify such provision so as to make it enforceable, and if such portion cannot be modified to be enforceable, the unenforceable portion shall be deemed severed from the remaining portions of this Agreement, which shall otherwise remain in full force and effect. If any portion of this Agreement is so found to be void or unenforceable for any reason in regard to any one or more persons, entities, or subject matters, such portion shall remain in full force and effect with respect to all other persons, entities, and subject matters. In the event Executive should in the future contend that Executive’s agreement to Section 8 hereof or release of claims pursuant to this Agreement (including, without limitation, the Bring Down Release) is for any reason void, imperfect, or incomplete, Executive may not pursue any claim against the Company (or any other party intended to be released thereby) to establish the invalidity of such agreement or release, or premised (in whole or in part) on the invalidity of such agreement or release, before or without repaying to the Company the full amount of the Payments provided to Executive under this Agreement and applicable statutes of limitations shall be deemed to run in regard to Executive’s claims without regard to the parties’ entry into this Agreement. The preceding sentence shall not operate to limit the scope or effect of Executive’s covenant not to sue as set forth in Section 11 .

     15.  Understanding and Authority . The parties understand and agree that all terms of this Agreement are contractual and are not a mere recital, and represent and warrant that they are competent to covenant and agree as herein provided.

     17.  Indemnification . No amendment, termination or repeal of Article VI of the Company’s by-laws or of the relevant provisions of the Delaware General Corporation Law or any other applicable laws shall affect or diminish in any way the rights Executive may have under the Company’s directors’ and officers’ liability insurance policy or the rights of Executive to indemnification under the provisions of Article VI of the Company’s by-laws with respect to any action, suit, proceeding or investigation arising out of or relating to any actions, transactions or facts occurring prior to the final adoption of such amendment, termination or repeal.

          6.1 Non-competition . The Executive shall not, at any time during the Restriction Period (as defined below), directly or indirectly engage in the business of, have any equity interest in or manage or operate any person, firm, corporation, partnership or other entity or business (whether as director, officer, employee, agent, representative, partner, security holder, consultant, proprietor, joint venturer or otherwise) that engages in any business which competes with any portion of the Business (as defined below) of the Company anywhere in the Restricted Area (as defined below). Nothing herein shall prohibit the Executive from being a passive owner of not more than 1% of the outstanding equity interest in any entity that is publicly traded, so long as the Executive has no active participation in the business of such entity.

          6.2 Non-solicitation . The Executive shall not, at any time during the Restriction Period, directly or indirectly, recruit or otherwise solicit or induce any employee, customer, subscriber or supplier of the Company or any prospective employee, customer, subscriber or supplier of the Company (i) to terminate its employment or arrangement with the Company, or (ii) to otherwise change its relationship with the Company. In addition, the Executive shall not, at any time during the Restriction Period, directly or indirectly, either for Executive or for any other person or entity employ such individual during his or her employment with the Company and for a period of six months after such individual terminates his or her employment with the Company.

The Executive agrees to refrain from disparaging the Company and its affiliates, including, without limitation, any of their respective products, services, technologies or practices, or any of their respective directors, officers, employees, agents, representatives or stockholders, either orally or in writing. Nothing in this Section 6.3 shall preclude the Company from making truthful statements that are reasonably necessary to comply with applicable law, regulation or legal process.

          6.4 Non-disclosure .

               (a) Except in connection with the faithful performance of the Executive’s duties as the President and Chief Executive Officer of the Company or as a member of the Board, the Executive shall, in perpetuity, maintain in confidence and shall not directly, indirectly or otherwise, use, disseminate, disclose or publish, or use for the Executive’s benefit or the benefit of any person, firm, corporation or other entity any confidential or proprietary information or trade secrets of or relating to the Company (including, without limitation, business plans, business strategies and methods, acquisition targets, intellectual property in the form of patents, trademarks and copyrights and applications therefor, ideas, inventions, works, discoveries, improvements, information, documents, formulae, practices, processes, methods, developments, source code, modifications, technology, techniques, data, programs, other know-how or materials, owned, developed or possessed by the Company, whether in tangible or intangible form, information with respect to the Company’s operations, processes, products, inventions, business practices, finances, principals, vendors, suppliers, customers, potential customers, marketing methods, costs, prices, contractual relationships, regulatory status, prospects and compensation paid to employees or other terms of employment) (collectively, the “ Confidential Information ”), or deliver to any person, firm, corporation or other entity any document, record, notebook, computer program or similar repository of or containing any such Confidential Information. The Executive and the Company hereby stipulate and agree that, as between them, any item of Confidential Information is important, material and confidential and affects the successful conduct of the businesses of the Company (and any successor or assignee of the Company). Notwithstanding the foregoing, Confidential Information shall not include any information that has been published in a form generally available to the public prior to the date the Executive proposes to disclose or use such information, provided that such publishing of the Confidential Information shall not have resulted from the Executive directly or indirectly breaching the Executive’s obligations under this Section 6.4 or any other similar provision by which the Executive is bound, or from any third-party breaching a provision similar to that found under this Section 6.4. For the purposes of the previous sentence, Confidential Information will not be deemed to have been published or otherwise disclosed merely because individual portions of the information have been separately published, but only if all material features comprising such information have been published in combination.

               (b) The Executive may respond to a lawful and valid subpoena or other legal process but (i) shall give the Company the earliest possible notice thereof, (ii) shall, as much in advance of the return date as possible, make available to the Company and its counsel the documents and other information sought and (iii) shall assist such counsel at Company’s expense in resisting or otherwise responding to such process.

               (c) On the Date of Termination, the Executive shall return any property of the Company (including, without limitation, proprietary information or intellectual property) that is within the Executive’s custody or control.

               (d) Nothing in this Section 6.4 shall prohibit the Executive from (i) disclosing information and documents when required by law, subpoena or court order (subject to the requirements of Section 6.4(b) above), (ii) disclosing information and documents to the Executive’s attorney or tax adviser for the purpose of securing legal or tax advice, (iii) disclosing

the Executive’s post-employment restrictions in this Agreement in confidence to any potential new employer, or (iv) retaining, at any time, the Executive’s personal correspondence, the Executive’s personal contacts and documents related to the Executive’s own personal benefits, entitlements and obligations.

          6.5 Acknowledgement . The Executive acknowledges that the restrictions contained in this Section 6 (a) are in consideration for the rights provided to Executive as set forth in this Agreement and the Company’s past and future provision of confidential information to Executive, and (b) represent a fair balance of the Company’s rights to protect its Business and Executive’s right to pursue employment. In the event the terms of this Section 6 shall be determined by any court of competent jurisdiction to be unenforceable by reason of its extending for too great a period of time or over too great a geographical area or by reason of its being too extensive in any other respect, it will be interpreted to extend only over the maximum period of time for which it may be enforceable, over the maximum geographical area as to which it may be enforceable, or to the maximum extent in all other respects as to which it may be enforceable, all as determined by such court in such action.

          6.6 Injunctive Relief . It is recognized and acknowledged by the Executive that a breach of the covenants contained in Section 6 will cause irreparable damage to the Company and its goodwill, the exact amount of which will be difficult or impossible to ascertain, and that the remedies at law for any such breach will be inadequate. Accordingly, the Executive agrees that in the event of a breach of any of the covenants contained in Section 6, in addition to any other remedy which may be available at law or in equity, the Company will be entitled to specific performance and injunctive relief.

          6.7 Section 6 Defined Terms . As used in this Section 6, (a) the term “ Company ” shall include the Company and its direct and indirect parents and subsidiaries, (b) the term “ Business ” shall mean the Business of the Company or its subsidiaries or affiliates and any business that is competitive with the business, work or projects of the Company or its subsidiaries or affiliates, as such business, work or projects may have been conducted or contemplated during the term of the Executive’s employment with the Company, (c) the term “ Restricted Area ” shall mean anywhere in the world and (d) the term “ Restriction Period ” shall mean the period beginning on the Effective Date and ending on the date upon which the Severance Period expires.

     7.  Miscellaneous .

          7.1 Successors . This Agreement shall be binding upon the Company and its successors and assigns. This Agreement shall inure to the benefit of and be enforceable by the Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. If the Executive should die while any amount would still be payable to the Executive or his family hereunder if the Executive had continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to the executors, personal representatives or administrators of the Executive’s estate.

          7.2 Notice . All notices, instructions and other communications given hereunder or in connection herewith shall be in writing. Any such notice, instruction or

communication shall be sent either (i) by registered or certified mail, return receipt requested, postage prepaid, or (ii) prepaid via a reputable nationwide overnight courier service, in each case addressed to the Company, at 64 Jackson Road, Devens, Massachusetts 01434, Attention: General Counsel, and to the Executive at the Executive’s last address reflected in the Company’s records (or to such other address as either the Company or the Executive may have furnished to the other in writing in accordance herewith).

          7.3 Employment by Subsidiary . For purposes of this Agreement, the Executive’s employment with the Company shall not be deemed to have terminated solely as a result of the Executive continuing to be employed by a wholly-owned subsidiary of the Company.

          7.5 Governing Law . The validity, interpretation, construction and performance of this Agreement shall be governed by the internal laws of the Commonwealth of Massachusetts, without regard to conflicts of law principles that would result in the application of the laws of any other jurisdiction.

          7.6 Waivers . No waiver by the Executive at any time of any breach of, or compliance with, any provision of this Agreement to be performed by the Company shall be deemed a waiver of that or any other provision at any subsequent time.

          7.7 Counterparts . This Agreement may be executed in counterparts, each of which shall be deemed to be an original but both of which together shall constitute one and the same instrument.

          7.8 Tax Withholding . Any payments provided for hereunder shall be paid net of any applicable tax withholding required under federal, state or local law.

          7.9 Entire Agreement . This Agreement sets forth the entire agreement of the parties hereto in respect of the subject matter contained herein and supersedes all prior agreements, promises, covenants, arrangements, communications, representations or warranties, whether oral or written, by any officer, employee or representative of any party hereto in respect of the subject matter contained herein; and any prior agreement of the parties hereto in respect of the subject matter contained herein is hereby terminated and cancelled.
