February, 2015 Uses in Bonus/Stock Awards Clause

Bonus/Stock Awards from Agreement

This Agreement (the Agreement), with an effective date of February 25, 2015, is entered into by Charles River Laboratories, Inc., with its principal place of business at 251 Ballardvale Street, Wilmington, Massachusetts 01887 (the Company) and Mr. Thomas F. Ackerman, an individual residing at 11 Atherton Circle, Lynnfield, MA 01940 (the Employee).

Bonus/Stock Awards. The Employee will receive any earned bonus amounts attributable to: (i) FY2014 performance payable in February, 2015 and (ii) FY2015 performance payable in February, 2016, consistent with past practices. Similarly, the Employee will retain the benefit of any stock awards previously made to him by the Company, including continued vesting and the lapsing of restrictions up to and including the last day of the Consulting Period. The Employee understands and agrees that he will not participate in the Companys EICP or any other bonus programs in FY2016, and that he will not receive any stock award from the Company in FY2016. The terms and conditions of any stock award agreements underlying any stock awards made to the Employee by the Company, either prior to or following the execution of this Agreement (collectively the Award Agreements) remain in full force and effect, with the Consulting Period counting toward the satisfaction of all vesting requirements or the lapsing of any restrictions. All such awards remain subject to the terms and conditions of the Award Agreements governing the respective awards, as well as the Companys 2007 Incentive Plan (the 2007 Plan). During FY2015, the Employee will be eligible to receive a stock award from the Company in February, consistent with past practices; provided, however, that the stock award to be made to the Employee in FY2015 will (i) be valued at $1 million at the time of grant; (ii) be subject to a one-year vesting requirement; and (iii) will contain a significant performance-based component tied to the Employees satisfactory transition of his current global responsibilities. For purposes of clarity, the provision of Consulting Services hereunder constitutes a service relationship with the Company, as contemplated by Section 4 of the 2007 Plan, which will commence without interruption upon the Employees conversion from employee to consultant status. To the extent that any of the Award Agreements (i) contemplates forfeiture of an award upon the cessation of employment or other service relationship; or (ii) provides a specified timeframe for the exercise of vested but unexercised stock option awards following cessation of such a relationship, the Administrator of the Plan expressly intends that the provision of Consulting Services under this Agreement constitutes such a service relationship.
