Compensation”: an amount comprised of 100% of the Annual Variable Bonus amount plus 100% of the Executive’s Base Salary, each as established by the Compensation Committee for the year in which termination occurs. 
  
 2.     Payments upon Termination. 
  
 2.1.    If (i) the Company terminates the
Executive’s employment at any time other than for Cause or upon the Executive’s death, or if the Executive terminates his employment for Good Reason, the Company will pay the Executive an amount equal to 100% of his Severance
Compensation, in twelve (12) equal monthly installments in arrears, and shall also pay him, on the date of termination, his Accrued Base Compensation plus his Accrued Incentive Compensation as of the termination date. 
  
 2.2.    The Company’s obligation to make the
payments under Section 2.1 above shall cease upon the Executive’s material breach of Executive’s “Employee Agreement,” as defined in Section 7 below, if such breach causes or is likely to cause material harm to the Company.

  
 2.3.    If (i) the Company terminates the
Executive’s employment at any time for Cause, the Company will pay the Executive his Accrued Base Compensation through the Termination Date. 
  
 2.4.    If the Company terminates the Executive’s employment upon the Executive’s death, the Company will pay the
Executive’s estate his Accrued Base Compensation plus his Accrued Incentive Compensation, payable in the manner set forth in Section 2.1 above. 
  
 2.5.    Upon any termination of the Executive’s employment with the Company to which Section 2.1 applies, the Company shall
maintain the benefits that the Executive is receiving as of the termination date and shall take such measures as are permissible under its medical, life, and disability insurance and any other employee benefit plans or programs to continue coverage
or reimbursement for the Executive (and the Executive’s family, if applicable) on the same terms (including any required contribution by the Executive) as immediately prior to such termination. Medical coverage under this section shall be
effected by the Executive making an election under COBRA. If it is not permissible to continue any such coverage under any such insurance plans, the Company will pay the Executive, as additional severance compensation, such amount, net of state and
federal income taxes payable by the Executive with respect thereto, as will be sufficient for the Executive to obtain such insurance coverage on an individual basis, limited to the amount payable based on the assumption that the Executive (and each
member of the Executive’s family who is to be covered) is a “standard risk” for insurance purposes. The Company’s obligations under this Section 2.5 shall continue only for so long as the Executive is entitled to receive payments
of Severance Compensation under Section 2.1. 
  

 3 








 3.    Limitation on Benefits. It is the intention of the parties that no payments by
the Company to Executive under this Agreement or any other agreement or plan pursuant to which Executive is entitled to receive payments or benefits shall be non-deductible to the Company by reason of the operation of Section 280G of the Internal
Revenue Code of 1986, as amended (the “Code”), relating to parachute payments. Accordingly, and notwithstanding any other provision of this Agreement or any such agreement or plan, if by reason of the operation of said Section 280G, any
such payments exceed the amount which can be deducted by the Company, such payments shall be reduced to the maximum amount which can be deducted by the Company. To the extent that payments exceeding such maximum deductible amount have been made to
Executive, Executive shall refund such excess payments to the Company with interest thereon at the Applicable Federal Rate determined under Section 1274(d) of the Code, compounded annually, or at such other rate as may be required in order that no
such payments shall be non-deductible to the Company by reason of the operation of said Section 280G. To the extent that there is more than one method of reducing the payments to bring them within the limitations of said Section 280G, then the
Executive shall be entitled to determine which method shall be followed in his sole discretion. 
  
 4.    Change of Control; Option Vesting. 
  
 If a Change of Control occurs while the Executive is employed by the Company then, whether or not Executive is terminated in connection with the Change of
Control and notwithstanding any contrary or inconsistent provision of any option granted to the Executive by the Company, the unvested options held by the Executive immediately before such Change of Control shall vest upon such Change of Control.

  
 5.    No Mitigation. 
  
 The Severance Compensation payable to the Executive shall not be reduced by
payments received by the Executive from a subsequent employer or otherwise. 
  
 6.    Mutual Release. Upon any termination of the Executive’s employment with the Company in connection with which benefits are provided under Section 2.1, the Executive shall execute the Mutual Release
attached hereto as Exhibit A and shall tender his resignation in writing from any position that the Executive holds as an officer or director of the Company. The Company agrees to execute such Mutual Release simultaneously. The
Executive’s execution and delivery of such Mutual Release and such written tender of resignation shall be a condition precedent to the effectiveness of and the Company’s obligations under Section 2.1. 
  
 7.    Invention, Non-Competition and Non-Disclosure Agreement. The
Executive agrees that the terms of the Employee Invention, Non-Competition and Non-Disclosure Agreement (the “Employee Agreement”) attached to this Agreement as Exhibit B are incorporated into and made a part of this Agreement and
supersede any and all prior agreements and understandings between the Executive and the Company relating to the subject matter of that Agreement.

 As an employee of the Company, I will have access to Confidential Information (as hereinafter defined) and Inventions (as
hereinafter defined) of the Company. I understand and agree that improper use or disclosure of such Confidential Information or Inventions would cause the Company substantial loss and damage. Accordingly, I have agreed to enter into this Agreement.

  
 2.    Agreement not to Compete with the
Company: 
  
 (a)    While employed by the
Company, and for a period of eighteen (18) months following the termination of such employment for any reason (unless such termination occurs before the first anniversary of the commencement of employment, in which case the period shall be one (1)
year following such termination), I shall not participate, directly or indirectly, on my own behalf or as owner, stockholder, partner, director, officer, manager, employee, agent or consultant, in any business, firm or corporation, or business or
other activity, which is in direct or indirect competition with the Company, which intends at any time to compete directly or indirectly with the Company, or which sells, licenses, leases or otherwise provides any products or services similar to any
products or services that are, or are proposed to be at the time of such termination, sold, licensed, leased or provided by the Company, in the United States. Notwithstanding the foregoing, I may purchase on a national securities exchange or in the
“over-the-counter” market securities representing up to 5% of the combined voting power of the outstanding securities of any company whose securities are listed on such exchange or publicly traded in such market. 
  
 (b)    While employed by the Company and for a period of

 3.    Definition of “Confidential Information”: 
  
 The term “Confidential Information” as used in this Agreement shall
mean all trade secrets, proprietary information and other data or information (and any tangible evidence, record or representation thereof), whether prepared, conceived or developed by an employee of the Company (including myself) or received by the
Company from an outside source, which is in the possession of the Company (whether or not the property of the Company), which is maintained in secrecy or confidence by the Company or any subsidiary of the Company or which might permit the Company or
any subsidiary of the Company or any of their respective customers to obtain a competitive advantage over competitors who do not have access to such trade secrets, proprietary information, or other data or information. Without limiting the
generality of the foregoing, Confidential Information shall include: 
  
 (a)    any idea, concept, invention, discovery, innovation, improvement, process, procedure, method, formula, development, computer program, training or service manual, test, test results, technical data, design,

proposed business of the Company. 
  
 4.    Unauthorized Disclosure of Confidential Information: 
  
 I shall at all times hold confidential all Confidential Information. During my employment by the Company, I shall use and disclose Confidential Information only to the extent necessary to perform my duties as an
employee of the Company and for the sole benefit of the Company, and, in any event, shall not disclose any Confidential Information to any person or entity outside the Company without the prior written direction or permission of a duly authorized
officer of the Company. After the termination of my employment by the Company, I shall not disclose to any person or entity, or make use of, any Confidential Information without the prior written permission of a duly authorized officer of the
Company. This provision shall not apply to any Confidential Information which the Company has voluntarily disclosed to the public or which has otherwise legally entered the public domain. 
  
 I understand that the Company has from time to time in its possession information which is claimed by others to be
confidential or proprietary and which the Company has agreed to keep confidential. I agree that all such information shall be Confidential Information for purposes of this Agreement. 
  

 10 








 5.    Property of the Company:

benefit, in any and all countries, patents, copyrights or other legal protection for all Confidential Information and Inventions, which by virtue of Section 5 hereof are the sole property of the Company and for publications pertaining to any of
them. I shall be entitled to reasonable compensation for any material amount of time spent by me in assisting the Company, under this Section 7. 
  
 8.    Exceptions to this Agreement: 
  
 Except as set forth below, I am subject to no contractual or other restriction or obligation which will in any way limit my activities on behalf of the

for any reason, or at any other time upon request of the Company, I shall return promptly any notebooks, computer programs, specifications, drawings, designs, blueprints, reproductions, sketches, notes, reports, proposals, business plans, manuals,
or copies of any of them, other documents or materials, tools, equipment, or other property belonging to the Company or its customers.

 If requested to do so by the Company, I agree to sign a Termination Certificate in which I confirm that I
have complied with the requirements of the preceding paragraph and that I am aware that certain restrictions imposed upon me by this Agreement continue after termination of my employment regardless of the manner of or reasons for such termination. I
understand, however, that my obligations under this Agreement will continue even if I do not sign a Termination Certificate. 
  
 10.    Miscellaneous Provisions: 
  
 (a)    In the event that any provision of this Agreement shall be determined to be unenforceable by any court of competent
jurisdiction by reason of its extending for too great a period of time or over too large a geographic area or over too great a range of activities, it shall be interpreted to extend only over the maximum period of time, geographic area or range of
activities as to which it may be enforceable. If, after application of the immediately preceding sentence, any provision of this Agreement shall be determined to be invalid, illegal or otherwise unenforceable by any court of competent jurisdiction,
the validity, legality and enforceability of the other provisions of this Agreement shall not be affected thereby. Any invalid, illegal or unenforceable provision of this Agreement shall be severable, and after any such severance, all other
provisions hereof shall remain in full force and effect. 
  
 (b)    This Agreement constitutes the entire agreement and understanding between the Company and me concerning the subject matter hereof. No modification, amendment, termination or waiver of this Agreement or any of the
provisions herein contained shall be binding upon me or the Company unless made in writing and signed by a duly authorized officer of the Company. Failure of the Company to insist upon strict compliance with any of the terms, covenants or conditions
hereof shall not be deemed a waiver of such terms, covenants and conditions. In the event of any inconsistency between this Agreement and any other contract between the Company and me, the provisions of this Agreement shall prevail. 
  
 (c)    This Agreement shall be binding upon me regardless
of the duration of my employment by the Company, the manner of or reasons for the termination of my employment by the Company, or the amount of my salary or wages. My obligations under this Agreement shall survive the termination of my employment by
the Company regardless of the manner of or reasons for such termination and regardless of whether such termination constitutes a breach of any other agreement I may have with the Company, and shall not in any way be modified, altered or otherwise
affected by such termination. My obligations under this Agreement shall be binding upon my heirs, legal representatives, successors and assigns, and the provisions of this Agreement shall inure to the benefit of and be binding on the legal
representatives, successors and assigns of the Company. 
  
 (d)    I recognize and acknowledge that money damages alone would not adequately compensate the Company for breach of any of my covenants, agreements or obligations herein, and therefore I agree that in the event of the
breach or threatened breach of any such covenant, agreement or obligation, in addition to all other remedies available to the Company, at law, in equity or otherwise, the Company shall be entitled to injunctive relief compelling specific performance
of, or other compliance with, the terms hereof. All rights and remedies hereunder are cumulative and are in addition to and not exclusive of any other rights and remedies available, at law, in equity, by agreement or otherwise. 
  

 13 








 (e)    This Agreement shall be governed by, and construed and enforced in accordance
with, the substantive laws of The Commonwealth of Massachusetts without regard to its principles of conflicts of laws, and shall be deemed to be effective as of the first day of my employment by the Company. This Agreement is executed under seal.
