Executive hereby accepts employment. The term of this Agreement (the Employment Period) shall commence on the Effective Date and end on November 24, 2011, or the date on which your employment is sooner terminated as provided below.
The Employment Period shall be automatically extended for successive periods of one year unless either party gives to the other written notice not less than thirty (30) days prior to the then-current expiration date that it or he does not wish
to extend the term of this Agreement.

2. CAPACITY AND PERFORMANCE:

devote approximately 50% of a regular work week and his best efforts, business judgment, skill and knowledge to the advancement of the business and interests of the Company and to the discharge of his duties and responsibilities hereunder. The
Executive shall comply with all lawful written policies of the Company in effect from time to time. The Executive may engage in other business activities and may pursue personal interests (including, without limitation, industry civil and charitable

together with the Chief Executive Officer and Board, formulate the strategic plan for the Company and, together with the Chief Executive Officer, oversee the execution of that corporate strategy. The Executive shall perform such other duties and

installments on February 24, May 24, August 24, and November24, of 2009, 2010 and 2011, and (ii) if the termination occurs on or before November 24, 2011, the Executive shall have the right to exercise the Stock

intent. Without limiting the scope of the immediately preceding sentence, the severance payments provided for under this Agreement shall be deferred for six (6) months from the effective date of the termination of the Executives
employment if immediately prior to such termination the Executive is, or in the Companys sole opinion may be, a specified employee as that term is defined in Section 409A(a)(2)(B)(i) of the Code (a Specified

full as of the Change in Control Date (except with respect to any portion of such stock options that have been exercised, forfeited or terminated prior to the date of the Change in Control), provided that all such stock options (including the
portion accelerated upon a Change of Control) must be exercised within the time periods set forth in the applicable stock option agreement and the 2001 Plan. If, in the event of a Reorganization Event (as defined in the 2001 Plan), stock options of
other employees of the Company granted under the 2001 Plan are assumed, or equivalent options are substituted, by the acquiror in the Reorganization Event, then the Stock Option and the July 2008 Option shall be assumed or substituted on
substantially the same terms as such other stock options. Change in Control Date means the first date on which a Change in Control occurs. Change in Control means an event or occurrence set forth in any one or more of
subsections (a) through (c) below (including an event or occurrence that constitutes a Change in Control under one of such subsections but is specifically exempted from another such subsection):

(a) the acquisition by an individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as
amended (the Exchange Act)) (an Acquiring Person) of beneficial ownership of any capital stock of the Company if, after such acquisition, such Acquiring Person beneficially owns (within the meaning of Rule 13d-3 promulgated
under the Exchange Act) 50% or more of either (i) the then-outstanding shares of common stock of the Company (the Outstanding Company Common Stock) or (ii) the combined voting power of the then-outstanding securities of the
Company entitled to vote generally in the election of directors (the Outstanding Company Voting Securities); provided, however, that for purposes of this subsection (a), the following acquisitions shall not constitute a Change in
Control: (i) any acquisition directly from the Company, (ii) any acquisition by the Company or (iii) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Company or any corporation controlled
by the Company; or

execution of this Agreement or (ii) who was nominated or elected subsequent to such date by at least a majority of the directors who were Continuing Directors at the time of such nomination or election or whose election to the Board was
recommended or endorsed by at least a majority of the directors who were Continuing Directors at the time of such nomination or election; or

(c) the consummation of a merger, consolidation, reorganization, recapitalization or statutory share exchange involving the Company or a sale or other disposition of all or substantially all of the assets of the Company (a Business
Combination), unless, immediately following such Business Combination, all or substantially all of the individuals and entities who were the beneficial owners of the Outstanding Company Common Stock and Outstanding Company Voting Securities
immediately prior to such Business Combination beneficially own, directly or indirectly, more than 50% of the then-outstanding shares of common stock and the combined voting power of the then-outstanding securities entitled to vote generally in the
election of directors, respectively, of the resulting or acquiring corporation in such Business Combination in substantially the same proportions as their ownership, immediately prior to such Business Combination, of the Outstanding Company Common
Stock and Outstanding Company Voting Securities, respectively.

such cessation, such product, technology or service is sold or actively engaged in by the Company; provided, however, that the provisions of this Section 11(a) (i) will not be deemed breached merely because the Executive owns less than 1%

securities exchange, (ii) will not be breached if the Executives employment with the Company is terminated because the Company becomes a subject of a proceeding under the Federal Bankruptcy Code and, subsequent to such termination, the

13. ENFORCEMENT OF COVENANTS: The Executive acknowledges that he has carefully read and considered all the terms and conditions of this
Agreement, including the restraints imposed upon him pursuant to Sections 11 and 12 hereof. The Executive acknowledges that the confidentiality and non-competition agreements set forth in Section 11 above and the agreement to cooperate set
forth in Section 12 above shall survive the termination of the Executives employment regardless of the reasons therefor. The Executive acknowledges

that the covenants contained in Sections 11 and 12 are reasonably necessary to protect the goodwill of the Company that is its exclusive property. The
Executive further acknowledges and agrees that, were he to breach any of the covenants contained in Sections 11 and 12 hereof, the damage may be irreparable. The Executive, therefore, agrees that the Company, in addition to any other remedies
available to it, shall be entitled seek preliminary and permanent injunctive relief against any breach by the Executive of any of said covenants, without making a showing that monetary damages would be inadequate or having to post bond, provided the
Company has made a prima facie showing of such a breach.

14. INVALIDITY: In the event that any provision of this Agreement
would be held to be invalid, prohibited, or unenforceable for any reason (including, but not limited to, any provision which may be held unenforceable because of the scope, duration or area of its applicability), this Agreement shall be construed as
if such invalid, prohibited or unenforceable provision had been more narrowly drawn so as not to be invalid, prohibited or unenforceable (and the court making any such determination as to any provision shall have the power to modify such scope,
duration or area or all of them, and such provision shall be applicable in such modified form) and shall not invalidate the remaining provisions of this Agreement or affect the validity or enforceability of such provisions.

15. WITHHOLDING: All payments made under this Agreement shall be reduced by any tax or other amounts required to be withheld under
applicable law.

16. ASSIGNMENT: Neither the Company nor the Executive may make any assignment of this Agreement or any
interest herein, by operation of law or otherwise, without the prior written consent of the other; provided, however, that the Company may assign its rights and obligations under this Agreement without the consent of the Executive in the
event that the Company shall hereafter effect a reorganization, or consolidate with or merge into any other Person, or transfer all or substantially all of its properties or assets to any other Person. This Agreement shall inure to the benefit of
and be binding upon the Company and the Executive, and their respective successors, executors, administrators, heirs and permitted assigns.

17. WAIVER: No waiver of any provision hereof shall be effective unless made in writing and signed by the waiving party. The failure of either party to require the performance of any term or obligation of this Agreement, or
the waiver by either party of any breach of this Agreement, shall not prevent any subsequent enforcement of such term or obligation or be deemed a waiver of any subsequent breach.

18. NOTICES: Any and all notices, requests, demands and other communications provided for by this Agreement shall be in writing and shall
be effective when delivered in person or deposited in the United States mail, postage prepaid, registered or certified, and addressed to the Executive at his last known address on the books of the Company or, in the case of the Company, at the
Companys principal place of business, to the attention of the Chairman of the Board, or to such other address as either party may specify by notice to the other actually received.

19. ENTIRE AGREEMENT: This Agreement constitutes the entire agreement between the parties and supersedes all prior communications,
agreements and understandings,



- 11 -



---

written or oral, with respect to the terms and conditions of the Executives employment (including the Executives prior engagement as a consultant
of the Company). For the sake of greater certainty, the July 2008 Option shall survive the execution of this Agreement.

20.
AMENDMENT: This Agreement may be amended or modified only by a written instrument signed by the Executive and an expressly authorized representative of the Company.

21. HEADINGS: The headings and captions in this Agreement are for convenience only and in no way define or describe the scope or content of
any provision of this Agreement.

22. COUNTERPARTS: This Agreement may be executed in two or more counterparts, each of which
shall be an original and all of which together shall constitute one and the same instrument.

23. GOVERNING LAW: This
Agreement shall be construed and enforced under and be governed in all respects by the laws of the Commonwealth of Massachusetts, without regard to the conflict of laws principles thereof.
