                           CHARLES RIVER LABORATORIES
                               Severance Agreement

      This will set forth our revised agreement regarding your severance.

      1. You will receive one-year of severance pay in exchange for your
agreement not to compete with CRL during the one-year severance period. You
will receive this severance pay even if you find employment during this period,
so long as the employment is not with a competitor.

      2. If at the end of a year you have not found full-time employment, then
CRL will, at its choosing, either release you from the non-compete or continue
your severance for up to an additional year until you find non-competing
employment.

      3. "Competitor" for this purpose means lab animal breeders and ascites
producers.

      4. This severance arrangement will apply if you are terminated by CRL for
any reason other than for "cause". "Cause" will be limited to the commission of
a serious crime, fraud, dishonesty, willful misconduct or total disregard for
your assigned duties.

      5. The outstanding balance of your one-year severance will be payable in
a lump-sum to your spouse, child or other designated family member in the event
you die during the initial year.

      6. Your CRL disability coverage will continue so long as the severance is
still in effect.

      7. CRL's contributions to your ESLIRP will continue so long as the
severance is in effect.

      8. You will be eligible for EICP for the year in which your termination
occurs, on at least a pro rata allocation basis.

      If we agree, please sign below, and this will modify the CRL Corporate
Officer Separation Plan as it applies to you.

            in the following form:

            In consideration of the benefits to be provided to you and as part
            of your fiduciary obligations to B&L, you agree that for a period of

            (a) Compete with any business of the Company engaged in or under
            active development by the Company or any of its subsidiaries. For

            or a 5% or more shareholder of any business or otherwise engaging in
            or assisting another to engage in any business. Without limiting the
            foregoing, the Company shall consider, on an as requested basis,
            modifications to your restrictions on competition where management
            of the Company believes the competitive impact on the Company to be
            minimal or otherwise manageable; or

            (b) Directly or indirectly solicit or hire any employee of the
            Company or any of its subsidiaries to work for or on behalf of you
            or any business in which you serve as an employee, an officer, a
            director, an owner, a partner or a 5% or more shareholder.
