(b)         The Severance Amount shall be equal to the sum of (A) the amount of the Executive’s then-current monthly base salary multiplied by twelve (12), plus (B) an amount in lieu of bonus equal to the product of the Executive’s target cash incentive bonus for the year in which termination of employment occurs, multiplied by the sum of (i) 1.0 plus (ii) a fraction

equal to the quotient of the number of days during such year on which the Executive was employed by the Company, divided by 365.

(c)          Continuation Benefits shall consist of the Company paying the difference between the cost of COBRA continuation coverage, should the Executive elect to receive it, for the Executive and any dependent who received health insurance coverage prior to termination of the Executive’s employment, and any premium contribution amount applicable to the Executive as of such termination, for a period of one year following the date of termination. Continuation Benefits otherwise receivable by the Executive will be reduced to the extent benefits of the same type are received by or made available to him or her during the applicable one-year period (and any such benefits received by or made available to the Executive shall be reported by him or her to the Company).

(ii)                                  a material diminution in the Executive’s authority or responsibilities, provided that a change in title or reporting relationship shall not, in and of itself, be deemed to constitute such a material diminution, or the assignment to the Executive of duties or responsibilities inappropriate to the office of [specify title];

(iii)                               a material diminution in the Executive’s compensation or benefits without the express written consent of the Executive, other than an across-the-board reduction in compensation levels that applies to all senior executives generally; or

(iv)                              any other action or inaction that constitutes a material breach by the Company of any written agreement under which the Executive provides services to the Company;

provided, that no such event or occurrence shall constitute an Event of Constructive Termination unless (x) written notice thereof is given by the Executive to the Company within ninety (90) days of its occurrence, (y) the Company shall fail to remedy or cure such event or occurrence within thirty (30) days following its receipt of such notice from the Executive, and (z) the Executive shall within sixty (60) days after the expiration of such 30-day period give written notice to the Company of his election to terminate his employment pursuant to this paragraph by reason of such event or occurrence.

(c)          the Executive’s failure to comply with lawful instructions not inconsistent with this Agreement given to the Executive by the Board of Directors, which failure is not cured or corrected within thirty (30) days after the Executive’s receipt of written notice from the Company referring to this paragraph and describing with specificity the instructions with which the Executive did not comply;

(d)         the Executive’s material failure to comply with reasonable policies, directives, standards and regulations adopted by the Company, including, without limitation, the Company’s policies regarding insider trading, except any such failure, that, if capable of cure, is remedied by the Executive within thirty (30) days after the Executive’s receipt of written notice from the Company referring to this paragraph and describing with specificity the failure of the Executive to comply; and

(e)          material breach by the Executive of the Company Proprietary Rights Agreement or any other written agreement between the Executive and the Company.

1.3.                            Voluntary Termination by Executive.

(a)         The Executive may voluntarily terminate his employment at any time by written notice to the Company, in which case the Executive shall receive no Severance Amount, no Continuation Benefits and no further payments or benefits shall be paid or payable to the Executive by the Company for any period after such termination of employment, except to the extent that Executive shall have accrued benefits under any plan adopted by the Company for the benefit of its employees generally and except for all compensation owing hereunder to the Executive as of the date of voluntary termination.

(b)         Notwithstanding the foregoing, upon the occurrence of an Event of Constructive Termination the Executive may, by written notice to the Company pursuant to clause (z) of Section 1.1 above, voluntarily terminate his employment, and in such event: (i) within ten (10) days of the date of such termination, the Company shall pay to the Executive in a lump sum the Severance Amount, plus all other compensation, including, without limitation, any commissions earned but not yet paid, owed by the Company to the Executive as of the date of his termination (ii) the Company shall provide to the Executive the Continuation Benefits for a period of twelve (12) months following such termination, and (iii) the remaining unvested portion of any stock option, restricted stock award, restricted stock unit or other compensatory stock-based award (each an “Award”) then held by the Executive shall be accelerated such that all such Awards shall be fully vested; provided, in the case of any Award the vesting of which is contingent in whole or in part upon the attainment of any Company or market performance condition that has not yet been satisfied, such condition shall be deemed to have been satisfied as of the date of termination at the level that would result in vesting of 100% of the number of shares stated as the target award.

1.4.                            Termination by the Company without Cause Following a Change in Control.

(a)                                 In the event that the Executive’s employment under this Agreement is terminated by the Company other than for Cause at any time during the twelve (12) month period following a Change in Control, then: (i), on the date of such termination, the Company shall pay to the Executive in a lump sum the Severance Amount, plus all other compensation, including, without limitation, any commissions earned but not yet paid, owed by the Company to the Executive as of the date of his termination, (ii) the Company shall provide to the Executive the Continuation Benefits for a period of twelve (12) months following such termination, and (iii) the remaining unvested portion of any Award then held by the Executive shall be accelerated in the manner provided in Section 1.3(b)(iii) above.

(b)                                 If during the twelve (12) month period following the occurrence of a Change in Control the employment of the Executive is terminated by the Company for Cause pursuant to paragraph 1.2(a) above, and if the charges of criminal conduct are subsequently dismissed, or the Executive is acquitted of such charges, then in such event the Executive’s termination shall be deemed to have been made without Cause, and in such event the Company shall pay to the Executive within thirty (30) days of such dismissal or acquittal, in a lump sum (i) the Severance Amount, plus all other compensation, including, without limitation, any commissions earned but not yet paid, owed by the Company to the Executive as of the date of his termination, (ii) an amount equal to the fair value of the Continuation Benefits for a period of twelve (12) months following the termination of his employment, and (iii) an amount equal to the fair value of the remaining unvested portion of any Awards that were held by the Executive immediately prior to such termination, giving effect to the acceleration of such Awards in the manner provided in Section 1.3(a)(iii) above, determined as of the date of such termination.

2.              Other Provisions.

2.1.                            Amounts Payable Less Withholding Taxes.  The amounts payable by the Company hereunder shall be less any federal, state or local withholding taxes and social security.

2.2.                            Excise Tax. Notwithstanding any other provisions of this letter agreement, in the event that any payment or benefit received or to be received by the Executive in connection with a Change in Control, whether pursuant to the terms of this agreement or any other plan, arrangement or agreement (all such payments and benefits, being hereinafter referred to as the “Total Payments”) would be subject (in whole or part), to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”), then, after taking into account any reduction in the Total Payments provided by reason of Section 280G of the Internal Revenue Code (the “Code”) in such other plan, arrangement or agreement, the severance payments hereunder shall be reduced to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax. The Total Payments shall be reduced by the Company in its reasonable discretion in the following order: (A) reduction of any cash payment, excluding any cash payment with respect to the acceleration of equity awards, that is otherwise payable to you that is exempt from Section 409A of the Code, (B) reduction of any other payments or benefits otherwise payable to you on a pro-rata basis or such other manner that complies with Section 409A of the Code and (C) reduction of any payment with respect to the acceleration of equity awards that is otherwise payable to you that is exempt from Section 409A of the Code.

Section 409A. It is intended that this Agreement comply with or be exempt from Section 409A of the Code and the Treasury Regulations and IRS guidance thereunder (collectively referred to as “Section 409A”).  Notwithstanding anything to the contrary in this Agreement, this Agreement shall, to the maximum extent possible, be administered, interpreted, and construed in a manner consistent with Section 409A.  If and to the extent required to comply with Section 409A, no payment or benefit required to be paid under this Agreement on account of termination of Executive’s employment shall be made unless and until Executive has a “separation from service” within the meaning of Section 409A.  In the case of any amounts payable under this Agreement that may be treated as payable in the form of “a series of installment payments,” as defined in Treasury Regulation Section 1.409A-2(b)(2)(iii), the right to receive such payments shall be treated as a right to receive a series of separate payments for purposes of such Treasury Regulation.  If Executive is a “specified employee” as determined pursuant to Section 409A as of the date of  termination of employment and if any payment or benefit provided for in this Agreement or otherwise both (x) constitutes a “deferral of compensation” within the meaning of Section 409A and (y) cannot be paid or provided in the manner otherwise provided without subjecting Executive to additional tax, interest, or penalties under Section 409A, then any such payment or benefit shall be delayed until the earlier of (i) the date which is 6 months after Executive’s “separation from service” within the meaning of Section 409A for any reason other than death, or (ii) the date of Executive’s death.  Any payment or benefit otherwise payable or to be provided to Executive upon or in the 6 month period following “separation from service” that is not so paid or provided by reason of this Section 2.3 shall be accumulated and paid or provided to Executive in a single lump sum, as soon as practicable (and in all events within 15 days) after the date that is 6 months after Executive’s “separation from service” (or, if earlier, as soon as practicable, and in all events within 15 days, after the date Executive’s death). All subsequent payments or benefits, if any, shall be payable or provided in accordance with the payment schedule applicable to each payment or benefit.  It is the intent of this Agreement to comply with the requirements of Section 409A so that none of the severance payments and benefits to be provided hereunder shall be subject to the additional tax imposed under Section 409A, and any ambiguities herein shall be interpreted to so comply.  The Company and Executive agree to work together in good faith to consider amendments to this Agreement and to

take such reasonable actions that are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to Executive under Section 409A.

2.3.                            Noncompetition Agreement and Release.  It shall be a condition to the receipt by the Executive of any payment or benefit pursuant to this Agreement that the Executive shall have executed and delivered to the Company a noncompetition agreement in substantially the form attached as Exhibit A hereto, and a general release (the “Release”) in substantially the form attached as Exhibit B hereto. To the extent that the Executive is already a party to a noncompetition agreement with the Company, the Executive acknowledges and agrees that such agreement is a binding and enforceable obligation of the Executive that inures to the benefit of the Company’s successors and assigns, including any corporation with which or into which the Company may be merged or which may succeed to its assets or business in a Change of Control. The timing of any payment or benefit pursuant to this Agreement shall be governed by the following provisions.  Executive must execute and deliver the Release within 45 days after termination of employment. If Executive has revocation rights, such rights must be exercised, if at all, not later than seven days after execution of the Release. Subject to the execution and effectiveness of such Release, any payments that, pursuant to this Section 2.4, would otherwise be payable within the 60 day period commencing on termination of Executive’s employment shall be paid in a lump sum within 10 days after execution of the Release; provided that, if the 60 day period begins in one calendar year and ends in the subsequent calendar year, the payment shall be made in the subsequent calendar year.

2.4.  Term. This Agreement shall expire on the later of (a) the first anniversary of the date of its execution or (b) if a Change in Control shall have occurred during the term of this Agreement (as extended below), the first anniversary of such Change in Control, or if later, (c) the expiration of the 60-day period referred to in clause (z) of Section 1.1(d) above; provided that on the third anniversary of the date of execution, and on the expiration date of any subsequent Extension Term, as defined below, this Agreement shall automatically be extended for an additional term (each an “Extension Term”) of one (1) year, unless the Company shall, not less than thirty (30) nor more than ninety (90) days prior to such anniversary or expiration date, as the case may be, notify the Executive in writing that it elects not to extend the Agreement. The expiration of this Agreement shall not affect the right of the Executive to receive any payment or benefit to which he became entitled by its terms prior to such expiration.

2.5. Notices.  Any notice or other communication required or permitted hereunder shall be in writing and shall be deemed given when delivered personally or sent by facsimile transmission (with confirmation) or, if sent by regular mail, three days after the date of deposit in the United States mails addressed as follows:

(a)         if to the Company, to:

(b)         if to the Executive, to:

or to such other address as either party may from time to time provide to the other by notice as provided in this section.

2.6.                            Entire Agreement.  This Agreement constitutes the entire agreement and understanding between the Company and the Executive, and supersedes all prior negotiations, agreements (including the Prior Agreement), arrangements, and understandings, both written or oral, between the Company and the Executive with respect to the subject matter and the Term of this Agreement.

2.7.                            Waiver or Amendment.

(a)         The waiver by either party of a breach or violation of any term or provision of this Agreement by the other party shall not operate or be construed as a waiver of any subsequent breach or violation of any provision of this Agreement or of any other right or remedy.

(b)         No provision in this Agreement may be amended unless such amendment is set forth in a writing that specifically refers to this Agreement and is signed by the Executive and the Company.

2.8.                            Governing Law.  This Agreement shall be governed by and construed in accordance with the laws of The Commonwealth of Massachusetts without regard to its conflict of laws rules.

2.9.                            Successors; Assignment.  The Company shall require any successor via a Change in Control (whether direct or indirect, by purchase, merger, consolidation or otherwise) to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. This Agreement shall inure to the benefit of, and shall be binding upon, each of the Company and the Executive and their respective heirs, personal representatives, legal representatives, successors and assigns.

2.10.                     Severability.  The invalidity of any one or more of the words, phrases, sentences, clauses or sections contained in this Agreement shall not affect the enforceability of the remaining portions of this Agreement or any part hereof.  If any part of this Agreement shall be declared invalid by a court of competent jurisdiction, this Agreement shall be construed as if such invalid part had not been inserted.

2.11.                     Section Headings.  The section and subsection headings contained in this Agreement are for reference purposes only and shall not affect any way the meaning, construction or interpretation of any or all of the provisions of this Agreement.

2.12.                     Counterparts.  This Agreement may be executed in any number of counterparts and by the separate parties hereto in separate counterparts, each of which shall be deemed to constitute an original and all of which shall be deemed to be one and the same instrument.

signing and returning it to the Company, this Agreement will become binding upon the Executive and the Company.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the day and year first written above.
