employed by the Corporation.
|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4. | Accelerated Vesting and Forfeiture.
|-- | -----------------------------------



| | (a) | Generally. Except as provided in either Section 4(b), Section 4(c) or Section 4(d) below, all Restricted Stock Units shall be forfeited if the
Employees employment with the Corporation terminates for any reason before the Scheduled Vesting Date.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---



| | (b) | Qualifying Employment Termination Prior to a Change of Control. If the Employees employment with the Corporation is terminated prior to both the Scheduled Vesting
Date and a Change of Control either (i) by the Corporation in a manner that triggers benefits to the Employee under Article III of the Officer Severance Agreement or (ii) as a result of Employees death or Disability, then this Award
shall immediately vest on a pro-rata basis, and the number of vested Restricted Stock Units shall equal 69,920 multiplied by a fraction, (i) the numerator which shall equal the number of fully completed months of service the Employee has
provided to the Corporation since the Grant Date (counting December 2009 as a fully completed month of service) through the date of the Employees employment termination, and (ii) the denominator which shall equal sixty (60), with the
product rounded up to the nearest whole Share. Any Restricted Stock Units that remain unvested after application of this Section 4(b) shall be immediately forfeited.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | Change of Control with New CEO. If, immediately before the effective date of a Change of Control, the Employee is employed by the Corporation but is not provided the
opportunity to serve as the Chief Executive Officer of the Corporation or its successor (CEO) following the Change of Control, then the Employees Restricted Stock Units under this Award shall become immediately and fully vested
upon the effective date of the Change of Control. Notwithstanding anything to the contrary in this Award Agreement, the Employees employment shall be deemed to have been terminated under this subsection (c) (and not under any other
subsection of this Section 4) if (i) his employment is terminated without Cause at the direction of a person or entity who has entered into an agreement with the Corporation, the consummation of which will constitute a Change of Control,
or (ii) if the Employee terminates his employment after an Impending Change of Control (as defined in the Executive Termination Agreement) for good reason that qualifies as an involuntary termination under Treas. Reg.
Sect. 1.409A-1(n).
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | Change of Control with Employee to Remain CEO. If the Employee remains employed as CEO upon the effective date of a Change of Control, then this Award shall immediately
vest on a pro-rata basis, and the number of vested Restricted Stock Units at that time shall equal 69,920 multiplied by a fraction, (i) the numerator which shall equal the number of fully completed months of service the Employee has provided to
the Corporation since the Grant Date (counting December 2009 as a fully completed month of service) through the effective date of the Change of Control, and (ii) the denominator which shall equal sixty (60), with the product rounded up to the
nearest whole Share.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (e) | Termination of Employment Following a Change of Control. If the Employees employment is terminated following a Change of Control as a result of an involuntary
termination as defined under Treas. Reg. Sect. 1.409A (other than by the Corporation for Cause), then the remainder of this Award shall be immediately and fully vested. For avoidance of doubt, an involuntary termination for
this purpose includes a termination of employment for good reason under the circumstances described in Treas. Reg. Sect. 1.409A-1(n)(2). If the Employees employment is terminated following a Change of Control as a result of death
or Disability, then this Award shall immediately vest on a pro-rata basis, and the aggregate number of vested Restricted Stock Units (after application of Section 4(d) and this Section 4(e)) at that time shall equal 69,920 multiplied by a
fraction, (i) the numerator which shall equal the number of fully completed months of service the Employee has provided to the Corporation since the Grant Date (counting December 2009 as a fully completed month of service) through the date of
the Employees death or the date of Employees termination of employment for Disability, as the case may be, and (ii) the denominator which shall equal sixty (60), with the product rounded up to the nearest whole Share. Any Restricted
Stock Units that remain unvested after application of this Section 4(e) shall be immediately forfeited.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|5. | Dividends. The Employee shall have no right to receive any dividends on or before the date on which the Shares underlying the RSUs are delivered to the Employee pursuant
to Section 6 below.
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---



|6. | Settlement. The Corporation shall deliver or cause to be delivered to the Employee or, if applicable, his or her legal guardian or legal representative, a certificate for
the Stock (or other evidence of the delivery of such Stock) with respect to a Restricted Stock Unit as soon as practicable (but in no event later than twenty business days) after it first becomes vested hereunder. Notwithstanding the foregoing, in
the event of a Change of Control, the Corporation (or its successor) shall deliver the form of consideration received by the Corporations stockholders in connection with a Change of Control in lieu of Stock subject to a contrary determination
by the Committee under Section 15 of the Plan; provided, however, that settlement shall, in all events, be made not later than two and one-half months after the calendar year in which there is a Change of Control.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|7. | Employee Rights. The Employees rights with respect to the Restricted Stock Units evidenced by this Award Agreement may not be sold, assigned, transferred, exchanged,
pledged, hypothecated or otherwise encumbered, and any attempt to do so shall be null and void. This Award Agreement does not confer upon the Employee any right to continued employment by the Corporation or subsidiary, nor shall it interfere in any
way with the right of the Corporation or a subsidiary to terminate the Employees employment at any time.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|8. | Right to Recover Payments under this Award Agreement. Notwithstanding anything to the contrary in this Award Agreement, if it is determined by the Committee that any
action or inaction by the Employee on and after the Grant Date constituted misconduct (as defined below), then the Corporation may recover all or any portion of the Shares delivered to the Employee under this Award Agreement, and the
Employee agrees to return any such Shares (or the proceeds realized by the Employee upon an earlier disposition of the Shares) to the Corporation.
|-- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | The Corporation may, in its sole discretion, affect any such recovery by obtaining repayment directly from the Employee, setting off the amount owed to it against any amount or
award (except to the extent that doing so would violate Section 409A of the Code) or any combination thereof. Misconduct for purposes of this Section 8 means either (a) the Employees misappropriation or embezzlement
of funds or property belonging to the Corporation or its subsidiaries, (b) the appropriation (or attempted appropriation) of a material business opportunity of the Corporation, including attempting to secure or securing any personal profit in
connection with any transaction entered into on behalf of the Corporation, or (c) the Employees engaging in activities that constitute a material breach or violation of any non-competition, non-solicitation or confidentiality obligation
or the Employee Code of Conduct (including its Rules of Conduct) dated October 26, 2006, and as may be amended from time to time.
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|9. | Miscellaneous.

| | (a) | The Employee shall have no rights of a shareholder with respect to any Stock subject to the Restricted Stock Units until such time, if any, as such Stock is actually delivered.
Shares delivered under this Award Agreement shall be subject to the Corporations insider trading policy (including but not limited to any blackout period), securities pre-clearance policy, stock ownership guidelines and any other restrictions
that may be imposed from time to time on the Corporations directors and officers.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | The Plan and this Award Agreement constitute the entire agreement between the Corporation and the Employee pertaining to the subject matter hereof, and supersede all prior or
contemporaneous written or verbal agreements and understandings between the parties.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | Except as provided in Section 10 below, this Award Agreement may be amended by the Corporation only through action of the Committee and the Employee.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | The Committee has full authority and discretion, subject only to the express terms of the Plan and this Award Agreement, to decide all matters relating to the administration and
interpretation of the Plan and this Award Agreement, and all determinations by the Committee shall be final, conclusive and binding upon the Corporation, and any subsidiary, the Employee and all interested parties.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---



| | (e) | The Employee shall make arrangements that are reasonably satisfactory to the Corporation so that it can meet its tax withholding obligations. The Employee may elect to satisfy,
in whole or in part, minimum tax withholding with respect to any Restricted Stock Units that vest under this Award Agreement by having the Corporation withhold from the Shares he would otherwise be entitled to receive pursuant to such Restricted
Stock Units a number of Shares having a Fair Market Value (determined as of the date of vesting) equal to such liability.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (f) | The number of Shares subject to this Award Agreement shall be subject to adjustment as provided in Section 11 of the Plan.
| | --- | --------------------------------------------------------------------------------------------------------------------------



| | (g) | The Corporation shall make reasonable efforts to comply with all applicable federal and state securities laws applicable to the Plan and this Award; provided, however, that the
Corporation shall not be obligated to deliver any Shares under this Award if the delivery thereof would result in a violation of any such law.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (h) | This Award Agreement shall be construed and enforced in accordance with, and governed by, the laws of the Commonwealth of Massachusetts.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------



| | (i) | Neither this Award nor any payment of Shares as described above shall be considered compensation for purposes of any employee benefit plan, agreement or arrangement sponsored,
maintained by or contributed to by the Corporation or any of its subsidiaries.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (j) | The Plan, including the definition of terms, is incorporated in this Award Agreement by reference and made a part of it. In the event of any conflict among the provisions of the
Plan document and this Award Agreement, the Plan document shall prevail. For avoidance of doubt, the vesting provisions set forth in this Award Agreement shall in all events apply and be deemed not to be in conflict with the Plan document.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|10. | Section 409A of the Code. It is intended that the provisions of this Award Agreement shall be exempt from the requirements of Section 409A of the Code as a
short-term deferral under Treas. Reg. Sect. 1.409A-1(b)(4), and all provisions of this Award Agreement shall be construed and interpreted in a manner consistent with this intention. The Corporation reserves the right to make amendments
to this Award Agreement as the Corporation deems necessary or desirable to avoid the imposition of additional taxes and interest under Section 409A of the Code. In any case, the Employee shall be solely responsible and liable for the
satisfaction of all additional taxes, interest and penalties that may be imposed on the Employee or for the Employees account in connection with this Award Agreement (including any additional taxes and interest under Section 409A of the
Code), and neither the Corporation nor any of its subsidiaries shall have any obligation to indemnify or otherwise hold the Employee harmless from any or all of such taxes, interest and penalties.
