 Terms of Restricted Stock Units 
 1. Plan Incorporated by Reference. The provisions of the Plan are incorporated into and made a part of this Agreement by this reference.
Capitalized terms used and not otherwise defined in this Agreement have the meanings given to them in the Plan. The Committee administers the Plan, and its determinations regarding the interpretation and operation of the Plan and this Agreement are
final and binding. The Board may in its sole discretion at any time terminate or from time to time modify and amend the Plan as provided therein. You may obtain a copy of the Plan without charge upon request to the Company’s Human Resources
Department. 
 2. Vesting of RSUs. The RSUs will vest, while you are employed by the Company or one of its Affiliates, for the
respective numbers of shares and on the scheduled vesting dates stated in the vesting schedule on the first page of this Agreement, subject to the other terms hereof. RSUs are an unfunded, unsecured obligation of the Company. You shall not earn any
rights under the RSUs except in conformity with such schedule and until all other conditions that are required to be met in order to issue the underlying shares have been satisfied. Subject to Section 6, within sixty (60) days after the
scheduled vesting date for any RSUs, the Company will deliver to you or your legal representative the number of shares underlying the number of vested RSUs associated with such scheduled vesting date on the vesting schedule (or such cash or other
property as the Committee determines). 
 3. Termination of RSUs. Upon termination of your employment with the Company
and its Affiliates for any reason, any of the RSUs that are unvested as of the termination date will be canceled for no value. Authorized leave of absence or absence on military or government service shall not constitute termination of your
employment for this purpose so long as either (a) such absence is for a period of no more than 90 calendar days or (b) your right to re-employment after such absence is guaranteed either by statute or by contract. 

4. Withholding Taxes. Upon the vesting of the RSUs, the Company shall withhold from issuance in settlement of such RSUs the number of shares of
Stock necessary to satisfy the minimum tax withholding obligations arising from such vesting with such shares of Stock valued at their Fair Market Value on the date of withholding; provided, that the Company may permit, at the discretion of the
President and Chief Executive Officer, the Treasurer and Chief Financial Officer, or the Executive Vice President, Chief Administrative Officer and General Counsel, a holder of RSUs to pay the associated tax withholding obligations to the Company in
cash (in lieu of the Company withholding shares of Stock), if such holder submits a written request therefor in advance of the vesting date for such RSUs and remits to the Company such payment no later than the date of delivery of the remaining
shares to the holder in settlement of the RSUs. 
 5. Termination; Forfeiture. Notwithstanding any other provision of this Agreement,
you shall be obligated to (a) transfer to the Company any shares, cash or other property previously issued upon vesting of RSUs and (b) pay to the Company all gains realized by any person from the disposition of any such shares or other
property if: (I) your employment with the Company or any Affiliate is terminated for cause or (II) following termination of employment for any reason, either (A) the Company determines that you engaged in conduct while an employee
that would have justified termination for cause or (B) you violate any applicable confidentiality or non-competition agreement with the Company or any Affiliate. Termination for cause means criminal conduct involving a felony in the U.S. or the
equivalent of a felony under the laws of other countries, material violations of civil law related to your job responsibilities, fraud, dishonesty, self-dealing, breach of your obligations regarding the Company’s intellectual property, or
willful misconduct that the Committee determines to be injurious to the Company. 
 6. Compliance with Law; Lock-Up Agreement. The
Company shall not be obligated to issue any shares of Stock or other securities upon vesting of the RSUs unless the Company is satisfied that all requirements of law or any applicable stock exchange in connection therewith (including without
limitation the effective registration or exemption of the issuance of such shares or other securities under the Securities Act of 1933, as amended, and applicable state securities laws) have been or will be complied with, and the Committee may
impose any restrictions on your rights as it shall deem necessary or advisable to comply with any such requirements; provided that the Company will issue such shares or other securities on the earliest date at which it reasonably anticipates that
such issuance will not cause such violation . You further agree hereby that, as a condition to the issuance of shares upon vesting of the RSUs, you will enter into and perform any underwriter’s lock-up agreement requested by the Company from
time to time in connection with public offerings of the Company’s securities.

 7. Rights as Stockholder. You shall have no rights as a stockholder with respect to any shares of
Stock or other securities covered by the RSUs until the issuance of such actual shares of Stock or other securities. No adjustment shall be made for dividends or other rights for which the record date occurs before the date such shares of Stock or
other securities are issued. 
 8. Effect on Your Employment. Neither the adoption, maintenance or operation of the Plan nor the award
of the RSUs confers upon you any right to continue your employment with the Company or any Affiliate, nor shall they interfere with the rights of the Company or any Affiliate to terminate or otherwise change the terms of such employment or service
at any time, including, without limitation, the right to promote, demote or reassign you from one position to another in the Company or any Affiliate. Unless the Committee otherwise provides in any case, your employment with an Affiliate shall be
deemed to terminate for purposes of the Plan when such Affiliate ceases to be an Affiliate of the Company. 
 9. Nontransferability.
You may not assign or transfer the RSUs or any rights with respect thereto except by will or by the laws of descent and distribution or to the extent expressly permitted in writing by the Committee. 
 10. Corporate Events. The terms of the RSUs may be changed without your consent as provided in the Plan upon a change in control of, or certain
other corporate events affecting, the Company. Without limiting the foregoing, the number and kind of shares or other securities or property issuable upon vesting of the RSUs may be changed, the vesting schedule may be accelerated, the RSUs may be
assumed by another issuer, or the RSUs may be terminated, as the Committee may consider equitable to the participants in the Plan and in the best interests of the Company. 
 11. Governing Law. This Agreement shall be governed by and construed and enforced in accordance with the applicable laws of the United States of
America and the law (other than the law governing conflict of law questions) of the Commonwealth of Massachusetts except to the extent the laws of any other jurisdiction are mandatorily applicable. 
 12. Amendment and Termination of the RSUs. The RSUs may be amended or terminated by the Company with or without your consent, as permitted by the
Plan.
