                 CHARLES RIVER LABORATORIES INTERNATIONAL, INC.
                               2000 INCENTIVE PLAN

1.        ADMINISTRATION

         Subject to the express provisions of the Plan, the Administrator has
the authority to interpret the Plan; determine eligibility for and grant Awards;
determine, modify or waive the terms and conditions of any Award; prescribe
forms, rules and procedures (which it may modify or waive); and otherwise do all
things necessary to implement the Plan. Once an Award has been communicated in
writing to a Participant, the Administrator may not, without the Participant's
consent, alter the terms of the Award so as to affect adversely the
Participant's rights under the Award, unless the Administrator has expressly
reserved the right to do so. In the case of any Award intended to be eligible
for the performance-based compensation exception under Section 162(m), the
Administrator shall exercise its discretion consistent with qualifying the Award
for such exception.

2.        LIMITS ON AWARD UNDER THE PLAN

         a. NUMBER OF SHARES. A maximum of 6,289,000, shares of Stock may be
delivered in satisfaction of Awards under the Plan. For purposes of the
preceding sentence, shares that have been forfeited in accordance with the terms
of the applicable Award and shares held back in satisfaction of the exercise
price or tax withholding requirements from shares that would otherwise have been
delivered pursuant to an Award shall not be considered to have been delivered
under the Plan. Also, the number of shares of Stock delivered under an Award
shall be determined net of any previously acquired Shares tendered by the
Participant in payment of the exercise price or of withholding taxes.

         b. TYPE OF SHARES. Stock delivered by the Company under the Plan may be
authorized but unissued Stock or previously issued Stock acquired by the Company
and held in treasury. No fractional shares of Stock will be delivered under the
Plan.

         c. CERTAIN SHARE LIMITS. The maximum number of shares of Stock for
which Stock Options may be granted to any person from and after adoption of the
Plan and prior to June 5, 2010, the maximum number of shares of Stock subject to
SARs granted to any person during such period and the aggregate maximum number
of shares of Stock subject to other Awards that may be delivered (or the value
of which may be paid) to any person during such period shall each be 2,000,000.
For purposes of the preceding sentence, the repricing of a Stock Option or SAR
shall be treated as a new grant to the extent required under Section 162(m).
Subject to these limitations, each person eligible to participate in the Plan
shall be eligible to receive Awards covering up to the full number of shares of
Stock then available for Awards under the Plan. No Awards may be granted under
the Plan after June 5, 2010, but previously granted Awards may extend beyond
that date.

         d. OTHER AWARD LIMITS. No more than $2,000,000 may be paid to any
individual with respect to any Cash Performance Award (other than an Award
expressed in terms of shares of Stock or units representing Stock, which shall
instead be subject to the limit set forth in Section 2.c. above). In applying
the dollar limitation of the preceding sentence: (A) multiple Cash Performance
Awards to the same individual that are determined by reference to performance
periods of one year or less ending with or within the same fiscal year of the
Company shall be subject in the aggregate to one limit of such amount, and (B)
multiple Cash Performance Awards to the same individual that are determined by
reference to one or more multi-year performance periods ending in the same
fiscal year of the Company shall be subject in the aggregate to a separate limit
of such amount.

3.        ELIGIBILITY AND PARTICIPATION

         The Administrator will select Participants from among those key
Employees, directors and other individuals or entities providing services to the
Company or its Affiliates who, in the opinion of the Administrator, are in a
position to make a significant contribution to the success of the Company and
its Affiliates. Eligibility for ISOs is further limited to those individuals
whose employment status would qualify them for the tax treatment described in
Sections 421 and 422 of the Code.

4.        RULES APPLICABLE TO AWARDS

         a.       ALL AWARDS

                  (1)      TERMS OF AWARDS. The Administrator shall determine
                           the terms of all Awards subject to the limitations
                           provided herein.

                  (2)      PERFORMANCE CRITERIA. Where rights under an Award
                           depend in whole or in part on satisfaction of
                           Performance Criteria, actions by the Company that
                           have an effect, however material, on such Performance
                           Criteria or on the likelihood that they will be
                           satisfied will not be deemed an amendment or
                           alteration of the Award.

                  (3)      ALTERNATIVE SETTLEMENT. The Company may at any time
                           extinguish rights under an Award in exchange for
                           payment in cash, Stock (subject to the limitations of
                           Section 2) or other property on such terms as the
                           Administrator determines, provided the holder of the
                           Award consents to such exchange.

                  (4)      TRANSFERABILITY OF AWARDS. Except as the
                           Administrator otherwise expressly provides, Awards
                           may not be transferred other than by will or by the
                           laws of descent and distribution and during a
                           Participant's lifetime an Award requiring exercise
                           may be exercised only by the Participant (or in the
                           event of the Participant's incapacity, the person or
                           persons legally appointed to act on the Participant's
                           behalf).

                  (5)      VESTING, ETC. Without limiting the generality of
                           Section 1, the Administrator may determine the time
                           or times at which an Award will vest (I.E., become
                           free of forfeiture restrictions) or become
                           exercisable and the terms on which an Award requiring
                           exercise will remain exercisable. Unless the
                           Administrator expressly provides otherwise:

                           (A)      immediately upon the cessation of a
                                    Participant's employment or other service
                                    relationship with the Company and its
                                    Affiliates, all Awards (other than Stock
                                    Options and SARs) held by the Participant
                                    (or by a permitted transferee under Section
                                    4.a.(4)) immediately prior to such cessation
                                    of employment or other service relationship
                                    will be forfeited if not then vested and,
                                    where exercisability is relevant, will cease
                                    to be exercisable;

                           (B)      except as provided in (C) and (D) below, all
                                    Stock Options and SARs held by a Participant
                                    (or by a permitted transferee under Section
                                    4.a.(4)) immediately prior to the cessation
                                    of the Participant's employment or other
                                    service relationship for reasons other than
                                    death, to the extent then exercisable, will
                                    remain exercisable for the lesser of (i) a
                                    period of three months or (ii) the period
                                    ending on the latest date on which such
                                    Stock Option or SAR could have been
                                    exercised without regard to this Section
                                    4.a.(5), and shall thereupon terminate;

                           (C)      all Stock Options and SARs held by a
                                    Participant (or by a permitted transferee
                                    under Section 4.a.(4)) immediately prior to
                                    the Participant's death, to the extent then
                                    exercisable, will remain exercisable for the
                                    lesser of (i) the one-year period ending
                                    with the first anniversary of the
                                    Participant's death or (ii) the period
                                    ending on the latest date on which such
                                    Stock Option or SAR could have been
                                    exercised without regard to this Section
                                    4.a.(5), and shall thereupon terminate; and

                           (D)      all Stock Options and SARs held by a
                                    Participant (or by a permitted transferee of
                                    the Participant under Section 4.a.(4)) whose
                                    cessation of employment or other service
                                    relationship is determined by the
                                    Administrator in its sole discretion to
                                    result from reasons which cast such
                                    discredit on the Participant as to justify
                                    immediate termination of the Award shall
                                    immediately terminate upon such cessation.

         Unless the Administrator expressly provides otherwise, a Participant's
"employment or other service relationship with the Company and its Affiliates"
will be deemed to have ceased, in the case of an employee Participant, upon
termination of the Participant's employment with the Company and its Affiliates
(whether or not the Participant continues in the service of the Company or its
Affiliates in some capacity other than that of an employee of the Company or its
Affiliates), and in the case of any other Participant, when the service
relationship in respect of which the Award was granted terminates (whether or
not the Participant continues in the service of the Company or its Affiliates in
some other capacity).

                  (6)      TAXES. The Administrator will make such provision for
                           the withholding of taxes as it deems necessary. The
                           Administrator may, but need not, hold back shares of
                           Stock from an Award or permit a Participant to tender
                           previously owned shares of Stock in satisfaction of
                           tax withholding requirements. In no event shall Stock
                           be tendered or held back by the Company in excess of
                           the minimum amount required to be withheld for
                           Federal, state, and local taxes.

                  (7)      DIVIDEND EQUIVALENTS, ETC. The Administrator may
                           provide for the payment of amounts in lieu of cash
                           dividends or other cash distributions with respect to
                           Stock subject to an Award if and in such manner as it
                           deems appropriate.

                  (8)      RIGHTS LIMITED. Nothing in the Plan shall be
                           construed as giving any person the right to continued
                           employment or service with the Company or its
                           Affiliates, or any rights as a shareholder except as
                           to shares of Stock actually issued under the Plan.
                           The loss of existing or potential profit in Awards
                           will not constitute an element of damages in the
                           event of termination of employment or service for any
                           reason, even if the termination is in violation of an
                           obligation of the Company or Affiliate to the
                           Participant.

                  (9)      SECTION 162(m). The Administrator in its discretion
                           may grant Performance Awards that are intended to
                           qualify for the performance-based compensation
                           exception under Section 162(m) and Performance Awards
                           that are not intended so to qualify. In the case of
                           an Award intended to be eligible for the
                           performance-based compensation exception under
                           Section 162(m), the Plan and such Award shall be
                           construed to the maximum extent permitted by law in a
                           manner consistent with qualifying the Award for such
                           exception. In the case of a Performance Award
                           intended to qualify as performance-based for the
                           purposes of Section 162(m), except as otherwise
                           permitted by the regulations at Treas. Regs. Section
                           1.162-27: (i) the Administrator shall preestablish in
                           writing one or more specific Performance Criteria no
                           later than 90 days after the commencement of the
                           period of service to which the performance relates
                           (or at such earlier time as is required to qualify
                           the Award as performance-based under Section 162(m));
                           (ii) payment of the Award shall be conditioned upon
                           prior certification by the Administrator that the
                           Performance Criteria have been satisfied; and (iii)
                           if the Performance Criteria with respect to the Award
                           are not satisfied, no other Award shall be provided
                           in substitution of the Performance Award. The
                           provisions of this Section 6.a.(9) shall be construed
                           in a manner that is consistent with the regulations
                           under Section 162(m).

                  (10)     OPTION AND SAR REPRICING. Options and SARs may not be
                           repriced without the approval of a majority of shares
                           voting on the matter.

         b.       AWARDS REQUIRING EXERCISE

                  (1)      TIME AND MANNER OF EXERCISE. Unless the Administrator
                           expressly provides otherwise, (a) an Award requiring
                           exercise by the holder will not be deemed to have
                           been exercised until the Administrator receives a
                           written notice of exercise (in form acceptable to the
                           Administrator) signed by the appropriate person and
                           accompanied by any payment required under the Award;
                           and (b) if the Award is exercised by any person other
                           than the Participant, the Administrator may require
                           satisfactory evidence that the person exercising the
                           Award has the right to do so.

                  (2)      EXERCISE PRICE. The Administrator shall determine the
                           exercise price of each Stock Option; PROVIDED, that
                           except as otherwise permitted by the regulations at
                           Treas. Regs. Section 1.162-27, each Stock Option
                           intended to qualify for the performance-based
                           exception under Section 162(m) of the Code and each
                           ISO must have an exercise price that is not less than
                           the fair market value of the Stock subject to the
                           Stock Option, determined as of the date of grant. An
                           ISO granted to an Employee described in Section
                           422(b)(6) of the Code must have an exercise price
                           that is not less than 110% of such fair market value.

                  (3)      PAYMENT OF EXERCISE PRICE, IF ANY. Where the exercise
                           of an Award is to be accompanied by payment, the
                           Administrator may determine the required or permitted
                           forms of payment, subject to the following: (a) all
                           payments will be by cash or check acceptable to the
                           Administrator, or, if so permitted by the
                           Administrator (with the consent of the optionee of an
                           ISO if permitted after the grant), (i) through the
                           delivery of shares of Stock which have been
                           outstanding for at least six months (unless the
                           Administrator approves a shorter period) and which
                           have a fair market value equal to the exercise price,
                           (ii) by delivery of a promissory note of the person
                           exercising the Award to the Company, payable on such
                           terms as are specified by the Administrator, (iii) if
                           the Stock is publicly traded, by delivery of an
                           unconditional and irrevocable undertaking by a broker
                           to deliver promptly to the Company sufficient funds
                           to pay the exercise price, or (iv) by any combination
                           of the foregoing permissible forms of payment; and
                           (b) where shares of Stock issued under an Award are

                           under the Plan shall be deemed to have been awarded
                           as a non-ISO (and to have been so designated by its
                           terms) unless the Administrator expressly provides
                           for ISO treatment that the Stock Option is to be
                           treated as an ISO.

         c.       AWARDS NOT REQUIRING EXERCISE

         Awards of Restricted Stock and Unrestricted Stock may be made in return
for either (i) services determined by the Administrator to have a value not less
than the par value of the Awarded shares of Stock, or (ii) cash or other
property having a value not less than the par value of the Awarded shares of
Stock plus such additional amounts (if any) as the Administrator may determine
payable in such combination and type of cash, other property (of any kind) or
services as the Administrator may determine.

5.        EFFECT OF CERTAIN TRANSACTIONS

         a.       MERGERS, ETC.

         Immediately prior to a Covered Transaction (other than an Excluded
Transaction in which the outstanding Awards have been assumed or substituted for
as provided below), all outstanding Awards shall vest and, if relevant, become
exercisable, all Performance Criteria and other conditions to any Award shall be
deemed satisfied, and all deferrals measured by reference to or payable in
shares of Stock shall be accelerated. Upon consummation of a Covered
Transaction, all Awards then outstanding and requiring exercise or delivery
shall terminate unless assumed by an acquiring or surviving entity or its
affiliate as provided below.

         In the event of a Covered Transaction, the Administrator may provide
for substitute or replacement Awards from, or the assumption of Awards by, the
acquiring or surviving entity or its affiliates on such terms as the
Administrator determines.

         b.       CHANGES IN AND DISTRIBUTIONS WITH RESPECT TO THE STOCK

                  (1)      BASIC ADJUSTMENT PROVISIONS. In the event of a stock
                           dividend, stock split or combination of shares,
                           recapitalization or other change in the Company's
                           capital structure, the Administrator will make
                           appropriate adjustments to the maximum number of
                           shares that may be delivered under the Plan under
                           Section 2.a. and to the maximum share limits
                           described in Section 2.c., and will also make
                           appropriate adjustments to the number and kind of
                           shares of stock or securities subject to Awards then
                           outstanding or subsequently granted, any exercise
                           prices relating to Awards and any other provision of
                           Awards affected by such change. For the avoidance of
                           doubt, the 6,289,000 and 2,000,000 share limits
                           expressed in Section 2 are intended to reflect the
                           increased number of shares resulting from the share
                           exchange approved on June 5, 2000; accordingly, no
                           further adjustment in those limits shall be made
                           under this Section 5.b. solely to reflect such
                           exchange.

                  (2)      CERTAIN OTHER ADJUSTMENTS. The Administrator may also
                           make adjustments of the type described in paragraph
                           (1) above to take into account distributions to
                           common stockholders other than those provided for in
                           Section 5.a. and 5.b.(1), or any other event, if the
                           Administrator determines that adjustments are
                           appropriate to avoid distortion in the operation of
                           the Plan and to preserve the value of Awards made
                           hereunder; PROVIDED, that no such adjustment shall be
                           made to the maximum share limits described in Section
                           2.c., or otherwise to an Award intended to be
                           eligible for the performance-based exception under
                           Section 162(m), except to the extent consistent with
                           that exception, nor shall any change be made to ISOs
                           except to the extent consistent with their continued
                           qualification under Section 422 of the Code.

                  (3)      CONTINUING APPLICATION OF PLAN TERMS. References in
                           the Plan to shares of Stock shall be construed to
                           include any stock or securities resulting from an
                           adjustment pursuant to Section 5.b.(1) or 5.b.(2)
                           above.

6.        LEGAL CONDITIONS ON DELIVERY OF STOCK

         The Company will not be obligated to deliver any shares of Stock
pursuant to the Plan or to remove any restriction from shares of Stock
previously delivered under the Plan until the Company's counsel has approved all
legal matters in connection with the issuance and delivery of such shares; if
the outstanding Stock is at the time of delivery listed on any stock exchange or
national market system, the shares to be delivered have been listed or
authorized to be listed on such exchange or system upon official notice of
issuance; and all conditions of the Award have been satisfied or waived. If the
sale of Stock has not been registered under the Securities Act of 1933, as
amended, the Company may require, as a condition to exercise of the Award, such
representations or agreements as counsel for the Company may consider
appropriate to avoid violation of such Act. The Company may require that
certificates evidencing Stock issued under the Plan bear an appropriate legend
reflecting any restriction on transfer applicable to such Stock.

7.        AMENDMENT AND TERMINATION

         Subject to the last sentence of Section 1, the Administrator may at any
time or times amend the Plan or any outstanding Award for any purpose which may
at the time be permitted by law, or may at any time terminate the Plan as to any
further grants of Awards;

                                       4
<PAGE>

PROVIDED, that (except to the extent expressly required or permitted by the
Plan) no such amendment will, without the approval of the stockholders of the
Company, effectuate a change for which stockholder approval is required in order
for the Plan to continue to qualify under Section 422 of the Code and for Awards
to be eligible for the performance-based exception under Section 162(m).

8.        NON-LIMITATION OF THE COMPANY'S RIGHTS

         The existence of the Plan or the grant of any Award shall not in any
way affect the Company's right to Award a person bonuses or other compensation
in addition to Awards under the Plan.

9.        GOVERNING LAW

            FORM OF CHANGE IN CONTROL AGREEMENT FOR CERTAIN OFFICERS
                      OF CHARLES RIVER LABORATORIES, INC.

                                    AGREEMENT

     This Agreement, dated ___________, 2004 (the "EFFECTIVE DATE"), is made by
and between Charles River Laboratories, Inc., a Delaware corporation (the
"COMPANY") and [NAME] (the "EXECUTIVE").

     WHEREAS, the Company considers it essential to the best interests of its
shareholders to foster the continuous employment of key management personnel;

     WHEREAS, the Board of Directors of the Company (the "BOARD") recognizes
that, as is the case with many publicly-held corporations, the possibility of a
Change in Control (as defined below) exists and that such possibility, and the
uncertainty and questions which it may raise among management, may result in the
departure or distraction of management personnel to the detriment of the Company
and its shareholders;

     WHEREAS, the Board has determined that appropriate steps should be taken to
reinforce and encourage the continued attention and dedication of members of the
Company's management, including the Executive, to their assigned duties without
distraction in the face of potentially disturbing circumstances arising from the
possibility of a Change in Control; and

     NOW THEREFORE, in consideration of the premises and the mutual covenants
herein contained, the Company and the Executive hereby agree as follows:

     1. DEFINED TERMS. Capitalized terms, not elsewhere defined in this
Agreement, are defined in Section 16 hereof.

     2. TERMS OF AGREEMENT. (a) This Agreement shall commence as of the
Effective Date and shall continue in effect while the Executive is employed by
the Company for a period of three years; PROVIDED, however, that commencing on
the third anniversary of the Effective Date and on each anniversary thereafter,
the term of this Agreement shall automatically be extended for one additional
year unless, not later than 90-days prior to any such anniversary date either
party shall have given notice that it does not wish to extend this Agreement.
Notwithstanding the foregoing, if a Change in Control shall have occurred during
the original or extended term of this Agreement, (i) this Agreement shall
continue in effect for a period of 36 months beyond the month in which such
Change in Control occurred and (ii) any notice of nonrenewal given by the
Company during the twelve months prior to such Change in Control shall be deemed

<PAGE>

revoked and this Agreement shall be reinstated as if never terminated in
accordance with such notice.

     (b) It is intended, and the parties hereto agree, that (i) the benefit, if
any, payable to the Executive under any other severance or termination pay plan,
arrangement or agreement of or with the Company shall be reduced by the amount
of any payment actually provided under Section 6.1 hereof, (ii) any option to
acquire shares of the Company's common stock awarded to the Executive under any
stock option or other long-term incentive plan of the Company shall become fully
exercisable upon the occurrence of a Change in Control during the term of the
Agreement, and (iii) and restrictions on any shares of restricted stock held by
the Executive shall fully lapse upon the occurrence of a Change in Control
during the term of this Agreement, provided that nothing herein shall otherwise
affect or modify the terms of any such option or restricted stock or the
Executive's right or obligations with respect thereof.

     3. COMPANY'S COVENANTS SUMMARIZED. In order to induce the Executive to
remain in the employ of the Company, and in consideration of the Executive's
covenant set forth in Section 4 hereof, the Company agrees to compensate the
Executive as set forth herein, upon the terms and under the conditions described
herein, in the event the Executive's employment with the Company is terminated
under the circumstances described below following a Change in Control and during
the term of this Agreement. No amount or benefit shall be payable under this
Agreement unless there shall have been (or under the terms hereof, there shall
be deemed to have been) a termination of the Executive's employment with the
Company following a Change in Control.

     4. THE EXECUTIVE'S COVENANTS. The Executive agrees that, subject to the
terms and conditions of this Agreement, in the event of a Change in Control
during the term of this Agreement, the Executive will remain in the employ of
the Company until the earliest of (a) a date which is six (6) months after the
date of such Change in Control, (b) the date, after such Change in Control, of
termination by the Executive of the Executive's employment for Good Reason, or
termination of Executive's employment by reason of Death, Disability or
Retirement, or (c) the termination by the Company, after such Change in Control,
of the Executive's employment for any reason.

     5. COMPENSATION OTHER THAN SEVERANCE PAYMENT.

         5.1. DISABILITY. Following a Change in Control during the term of this
Agreement, during any period that the Executive fails to perform the Executive's
full-time duties with the Company as a result of incapacity due to physical or
mental illness, the Company shall continue to pay the Executive's full salary to
the Executive at the rate in effect at the commencement of any such period,
together with all compensation and benefits payable to the Executive under the
terms of any compensation or benefit plan, program or arrangement maintained by
the Company during such period, until the Executive's employment is terminated
by the Company for Disability.

<PAGE>

         5.2. SALARY CONTINUATION. If the Executive's employment shall be
terminated for any reason following a Change in Control and during the term of
this Agreement, the Company shall pay the Executive's full salary to the
Executive through the Date of Termination at the rate in effect at the time the
Notice of Termination is given, together with all compensation and benefits
payable to the Executive through the Date of Termination under the terms of any
compensation or benefit plan, program or arrangement maintained by the Company
during such period.

         5.3. OTHER POST-TERMINATION COMPENSATION. If the Executive's employment
shall be terminated for any reason following a Change in Control and during the
term of this Agreement, the Company shall, except as provided in Section 2
above, pay the Executive's normal post-termination compensation and benefits to
the Executive as such payments become due. Such post-termination compensation
and benefits shall be determined under, and paid in accordance with, the
Company's retirement, insurance and other compensation or benefit plans,
programs, agreements or arrangements.

     6. COMPANY OBLIGATIONS UPON TERMINATION. If, during the term of this
Agreement and on or before the first anniversary of a Change in Control, (i) the
Company shall terminate the Executive's employment other than for Cause, Death
or Disability or (ii) the Executive shall terminate his employment for Good
Reason, then the Company shall pay to the Executive the payments set forth in
Sections 6.1, 6.2, if applicable, 6.3 and 6.4 hereof (collectively, the
"SEVERANCE PAYMENTS") in addition to the payments and benefits described in
Sections 5 and 6.6 hereof. The Executive's employment shall be deemed to have
been terminated following a Change in Control by the Company without Cause or by
the Executive with Good Reason if the Executive's employment is terminated
without Cause prior to a Change in Control at the direction of a Person who has
entered into or has proposed to enter into an agreement with the Company the
consummation of which will constitute a Change in Control, or if the Executive
terminates his employment with Good Reason prior to a Change in Control if the
circumstances or event which constitutes Good Reason occurs at the direction of
such Persons; PROVIDED in either case that a Change in Control involving such
other Person is consummated within 12 months after any such direction.

         6.1. SEVERANCE PAYMENT. In lieu of any further salary payments to the
Executive for periods subsequent to the date of Termination, the Company shall
pay the Executive a lump sum severance payment, in cash, equal to [ ] times
(i.e., [ ] of) the sum of the Executive's then base salary plus the target bonus
contained in the Executive Bonus Plan for the fiscal year in which the Date of
Termination occurs.

         6.2. GOLDEN PARACHUTE EXCISE TAX. The Company intends that the
Executive shall generally not bear the economic effect of the excise tax imposed
by Section 4999 of the Internal Revenue Code on so-called golden parachute
payments. This provision shall be implemented in accordance with the provisions
of Annex 1. However, if a small (up to 15%) reduction in the Executive's
entitlements would greatly minimize

<PAGE>

the Company's costs in providing the excise tax protection, the Company will
reduce the amounts paid to the Executive hereunder to that small extent.

         6.3. RETIREMENT PLAN PAYMENTS. In the event the Executive was a
participant in the Charles River Laboratories, Inc. Pension Plan (or any
successor plan thereto) (the "PENSION PLAN") on or prior to the Date of
Termination, the Company shall pay to the Executive a separate lump-sum
supplemental retirement benefit (the "SUPPLEMENTAL RETIREMENT AMOUNT") equal to
the difference between (1) the actuarial equivalent of the benefit payable under
the Pension Plan which the Executive would receive if the Executive's employment
continued for the [ ] years following the Date of Termination and if his
compensation during such number of years increased at a rate of 4% per year from
the level in effect on the Date of Termination, and (2) the actuarial equivalent
of the Executive's actual benefit (paid or payable), if any, under the Pension
Plan. The amounts to be paid to the Executive under this Section shall be paid
out of the Pension Plan trust, to the extent permissible under applicable law.
For purposes of calculating the actuarial equivalents referred to in (1) and (2)
above, the Company shall use the actuarial assumptions utilized with respect to
the Pension Plan during the 90-day period immediately preceding the Change in
Control Date and shall assume that all accrued benefits are fully vested and
that benefit accrual formulas in effect during any years after the Date of
Termination are no less advantageous to the Executive than those in effect
during the 90-day period immediately preceding the Change in Control Date.

         6.4. ESLIRP PAYMENT. In the event that the Executive was a participant
in the Charles River Laboratories, Inc. Executive Supplemental Life Insurance
Retirement Plan (the "ESLIRP") on or prior to the Date of Termination, the
Company shall pay to the Executive a separate lump-sum supplemental retirement
benefit (the "ESLIRP PAYMENT") in discharge of the Company's obligations under
the ESLIRP equal to the actuarial equivalent of the Executive's benefit accrued
through the Date of Termination under the ESLIRP. The ESLIRP Payment shall be
calculated (i) utilizing the actuarial assumptions specified by Section
417(e)(3)(A) of the Internal Revenue Code, and in the case of the interest rate
specified under subparagraph (ii)(II) of such section, using such rate
established for the month of November of the year preceding the year in which
the payment occurs; (ii) assuming that the Executive's employment continued for
[ ] years following the Date of Termination, and (iii) assuming that the
Executive's compensation during such number of years referred to in (ii)
increased at a rate of 4% per year from the level in effect on the Date of
Termination. Notwithstanding the foregoing, however, to the extent the ESLIRP
Payment is funded through a trust of which the Executive is a beneficiary, such
amount to the extent so funded shall be paid from such trust. In the event that
the provisions of this subsection are in conflict with provisions of the ESLIRP,
the provisions of this Agreement shall prevail if the provisions of this
Agreement are more favorable to the Executive.

         6.5. TIMING OF PAYMENT. The payment provided for in Section 6.1 hereof
shall be made not later than the fifth day following the Date of Termination,
provided, however, that if the amount of such payment, and the limitation on
such payment set forth

<PAGE>

in Section 6.2 hereof, cannot be finally determined on or before such day, the
Company shall pay to the Executive on such day an estimate, as determined in
good faith by the Company, of the minimum amount of such payment to which the
Executive is clearly entitled and shall pay the remainder of such payment
(together with interest at the rate provided in Section 1274(b)(2)(B) of the
Code) as soon as the amount thereof can be determined but in no event later than
the 30th day after the Date of Termination. In the event that the amount of the
estimated payment exceeds the amount subsequently determined to have been due,
such excess shall be paid back to the Company within five business days after
demand by the company and such payment shall not be considered a loan, therefore
no interest shall be due or payable. At the time that payments are made under
this Section 6 the Company shall provide the Executive with a written statement
setting forth the manner in which such payments were calculated and the basis
for such calculation including, without limitation, any opinions or other advice
the Company has received from outside counsel, auditors or consultants (and any
such opinions or advice which are in writing shall be attached to the
statement).

         6.6. PAYMENT OF LEGAL FEES AND EXPENSE. The Company shall pay to the
Executive all legal fees and expenses incurred by the Executive as a result of
or in connection with a termination of employment (other than any such
termination by the Company for Cause) following a Change in Control and during
the term of the Agreement (including all such fees and expenses, if any,
incurred in good faith in disputing any such termination or in seeking in good
faith to obtain or enforce any benefit or right provided by the Agreement or in
connection with any tax audit or proceeding to the extent attributable to the
application of Section 4999 of the Code to any payment or benefit provided
hereunder). Such payments shall be made within five business days after delivery
of the Executive's written request for payment accompanied with such evidence of
fees and expenses incurred as the Company reasonably may require.

         6.7. CONTINUATION OF BENEFITS. If the Executive's employment terminates
as provided in Section 6, (a) the Company shall, for [ ] years following the
Date of Termination, or such longer period as any plan, program, practice or
policy may provide, continue benefits to the Executive and/or the Executive's
family at least equal to those which would have been provided had the
Executive's employment not been terminated, in accordance with the plans,
programs, practices and policies in effect and applicable generally to other
peer executives and their families during the 90-day period immediately
preceding the Effective Date that provided for group health, dental and life
insurance and other welfare-type plans, or if more favorable to the Executive,
in accordance with such plan, program, practice or policy as in effect generally
at any time thereafter with respect to other peer executives of the Company and
its affiliated companies; PROVIDED, however, that if the Executive becomes
employed by another employer and is eligible to receive medical or other welfare
benefits under another employer provided plan, the medical and other welfare
benefits described herein shall be secondary to those provided under such other
plan during such applicable period of eligibility. For purposes of determining
eligibility of the Executive for retiree benefits pursuant to such plans,
practices, programs and policies, the Executive shall be considered to have
remained employed until the end

<PAGE>

of the [ ] year period following the Date of Termination and to have retired on
the last day of such period.

            (b) Executive shall be permitted to purchase his then currently
Company-leased vehicle in accordance with the most attractive terms available
under such lease.

            (c) The Company shall provide (or reimburse) Executive with 26 weeks
of fully paid outplacement services, up to a maximum of $[ ].

     7. TERMINATION PROCEDURES AND COMPENSATION DURING DISPUTE.

            7.1. NOTICE OF TERMINATION. After a Change in Control and during the
term of this Agreement, any purported termination of the Executive's employment
(other than by reason of Death) shall be communicated by written Notice of
Termination from one party hereto to the other party in accordance with Section
10 hereof. For purposes of this Agreement, a "NOTICE OF TERMINATION" shall mean
a notice which shall indicate the specific termination provision in this
Agreement relied upon and shall set forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination of the Executive's
employment under the provision so indicated. Further, a Notice of Termination
for Cause is required to include a copy of a resolution duly adopted by the
affirmative vote of not less than three-quarters of the entire Board at a
meeting of the Board which was called and held for the purpose of considering
such termination (after reasonable notice to the Executive and an opportunity
for the Executive, together with his counsel, to be heard before the Board)
finding that, in the good faith opinion of the Board, the Executive was guilty
of conduct set forth in the definition of Cause herein, and specifying the
particulars thereof in detail.

            7.2. DATE OF TERMINATION. "DATE OF TERMINATION" with respect to any
termination of the Executive's employment after a Change in Control and during
the term of this Agreement, shall mean (a) if the Executive's employment is
terminated for Disability, 30 days after Notice of Termination is given
(provided that the Executive shall not have returned to the full-time
performance of the Executive's duties during such 30-day period), and (b) if the
Executive's employment is terminated for any other reason, the date specified in
the Notice of Termination (which, in the case of termination by the Company,
shall not be less than 30 days (except in the case of a termination for Cause),
and, in the case of a termination by the Executive, shall not be less than 15
days nor more than 60 days, respectively, from the date of such Notice of
Termination is given).

            7.3. DISPUTE CONCERNING TERMINATION. Notwithstanding any provision
of Section 7.2 hereof to the contrary, if within 15 days after Notice of
Termination is received, or, if later, prior to the Date of Termination (as
determined without regard to this Section 7.3), the party receiving such Notice
of Termination notifies the other party in writing that a dispute exists
concerning the termination, the Date of Termination shall be the date on which
the dispute is finally resolved, either by mutual written agreement of the
parties or by a final judgment, order or decree of a court of competent
jurisdiction (which is not appealable or with respect to which the time for
appeal therefrom has

<PAGE>

expired and no appeal has been perfected); provided that the Date of Termination
shall be extended by a notice of dispute only if such notice is given in good
faith and the party giving such notice pursues the resolution of such dispute
with reasonable diligence. For the purposes of the preceding sentence, a dispute
concerning termination shall be deemed finally resolved if, within 30 days of an
arbitration award concerning such dispute, neither party commences an action in
any court seeking the modification of or other relief from such award.

            7.4. COMPENSATION DURING DISPUTE. If a proposed termination occurs
following a Change in Control and during the term of this Agreement, and such
termination is disputed in accordance with Section 7.3 hereof, the Company shall
continue to pay the Executive the full compensation in effect when the notice
giving rise to the dispute was given (including, but not limited to, salary) and
continue the Executive as a participant in all compensation, benefit and
insurance plans in which the Executive was participating when the notice giving
rise to the dispute was given, until the dispute is finally resolved in
accordance with Section 7.3 hereof. Amounts paid under this Section 7.4 are in
addition to all other amounts due under this Agreement (other than those due
under Section 5.2 hereof).

     8. NO MITIGATION; SET-OFF. The Company agrees that, if the Executive's
employment by the Company is terminated during the term of this Agreement, the
Executive is not required to seek other employment or to attempt in any way to
reduce any amounts payable to the Executive by the Company pursuant to this
Agreement. Further, except as provided in Section 6.7, the amount of any payment
or benefit provided for in this Agreement shall not be reduced by any
compensation earned by the Executive as the result of employment by another
employer, by retirement benefits, by offset against any amount claimed to be
owed by the Executive to the Company or otherwise. The Company's obligation to
make the payments provided in this Agreement and otherwise to perform its
obligations hereunder shall not be affected by any set-off, counterclaim,
recoupment, defense or other claim, right or action which the Company may have
against the Executive.

         9. SUCCESSORS. The Company will require any successor (whether direct
or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to expressly
assume and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place, unless such obligations are binding upon such successor by
operation of law. Failure of the Company to obtain such assumption and agreement
prior to the effectiveness of any such succession shall be a breach of this
Agreement and shall entitle the Executive to compensation from the Company in
the same amount and on the same terms as the Executive would be entitled to
hereunder if the Executive were to terminate the Executive's employment for Good
Reason after a Change in Control, except that for purposes of implementing the
foregoing the date on which any such succession becomes effective shall be
deemed the Date of Termination.

time of any breach by the other party hereto of, or compliance with, any

each of which shall be deemed to be an original but all of which together will

with the commercial rules of the American Arbitration Association ("AAA")
then in effect. Unless a mutually acceptable arbitrator shall have been
selected by the parties within 30 days of the initiation of arbitration

the AAA, the AAA shall designate such arbitrator. Judgment may be entered on
the arbitrator's award in any court having jurisdiction, provided, however,
that the Executive shall be entitled to seek specific performance of his
right to be paid until the Date of Termination during the pendency of any
dispute or controversy arising under or in connection with this Agreement.

                    of the Change in Control, or the failure by the Company to
                    provide the Executive with the number of paid vacation days
                    to which the Executive is entitled on the basis of years of
                    service with the Company in accordance with the Company's

                                                                       Annex 1

     (a) Anything in the Agreement to the contrary notwithstanding but subject
to paragraph (b) of this Annex, in the event it shall be determined that any
payment or distribution by the Company to or for the benefit of Executive,
whether paid or payable or distributed or distributable pursuant to the terms of
the Agreement or otherwise (a "PAYMENT"), would be subject to the excise tax
imposed by Section 4999 of the Code or similar section or any interest or
penalties with respect to such excise tax (such excise tax, together with any
such interest and penalties, are hereinafter collectively referred to as the
"EXCISE TAX"), Executive shall be entitled to receive an additional payment (a
"GROSS-UP PAYMENT") in lump sum in an amount such that after payment by
Executive of all taxes (including any interest or penalties imposed with respect
to such taxes), including any Excise Tax, imposed upon the Gross-Up Payment,
Executive retains an amount of the Gross-Up Payment equal to the Excise Tax
imposed upon the Payment.

     (b) Notwithstanding paragraph (a) of this Annex, if the aggregate value of
the Payment is less than 315% of the Executive's "base amount" (as defined in
Section 280G(b)(3) of the Code), then the Executive shall not be entitled to any
Gross-Up Payment and, instead, the Payment shall be reduced to an amount equal
to $1.00 less than 300% of the "base amount".

     (c) Subject to the provisions of paragraph (d) of this Annex, all
determinations required to be made under this Annex, including whether a
Gross-Up Payment is required and the amount of such Gross-Up Payment, shall be
made at the Company's expense by an accounting firm selected by the Company and
acceptable to the Executive which is designated as one of the four (4) largest
accounting firms in the United States (the "ACCOUNTING FIRM") which shall
provide detailed supporting calculations both to the Company and the Executive
within 15 business days of termination of employment under the Agreement, if
applicable, or such earlier time as is requested by the Executive or the
Company. When calculating the amount of the Gross-Up Payment, the Executive
shall be deemed to pay:

               (i) federal income taxes at the highest applicable marginal rate
          of federal income taxation for the calendar year in which the Gross-Up
          Payment is to be made, and

               (ii) any applicable state and local income taxes at the highest
          applicable marginal rate of taxation for the calendar year in which
          the Gross-up Payment is to be made, net of the maximum reduction in
          federal income taxes which could be obtained from deduction of such
          state and local taxes if paid in such year.

     If the Accounting Firm determines that no Excise Tax is payable by the
Executive, it shall state in writing to Executive that Executive has substantial
authority not to report any Excise Tax on Executive's federal income tax return.
Any determination by the Accounting Firm shall be binding upon the Company and
Executive. As a result of the uncertainty in the application of Section 4999 of
the Code at the time of the initial

<PAGE>

determination by the Accounting Firm hereunder, it is possible that Gross-Up
Payments which will not have been made by the Company should have been made
("UNDERPAYMENT"), consistent with the calculations required to be made
hereunder. In the event that the Company exhausts its remedies pursuant to
paragraph (d) of this Annex, and Executive is thereafter required to make a
payment of any Excise Tax, the Accounting Firm shall determine the amount of the
Underpayment that has occurred and any such Underpayment shall be promptly paid
by the Company to or for the benefit of the Executive.

     (d) The Executive shall notify the Company in writing of any claim by the
Internal Revenue Service that, if successful, would require the payment by the
Company of the Gross-Up Payment. Such notification shall be given as soon as
practicable but no later than 10 business days after Executive knows of such
claim and shall notify the Company of the nature of such claim and the date on
which such claim is requested to be paid. Executive shall not pay such claim
prior to the expiration of the 30-day period following the date on which
Executive gives such notice to the Company (or such shorter period ending on the
date that any payment of taxes with respect to such claim is due). If the
Company notifies Executive in writing prior to the expiration of such period
that it desires to contest such claim, Executive shall:

               (iii) give the Company any information reasonably requested by
          the Company relating to such claim,

               (iv) take such action in connection with contesting such claim as
          the Company shall reasonably request in writing from time to time
          including, without limitation, accepting legal representation with
          respect to such claim by an attorney reasonably selected by the
          Company,

               (v) cooperate with the Company in good faith in order effectively
          to contest such claim, and

               (vi) permit the Company to participate in any proceedings
          relating to such claim;

provided, however, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify and hold Executive harmless, on an
after-tax basis, for any Excise Tax or income tax, including interest and
penalties with respect thereto, imposed as a result of such representation and
payment of costs and expenses.

         Without limitation on the foregoing provisions of this paragraph (d),
the Company shall control all proceedings taken in connection with such contest
and, at its sole option, may pursue or forego any and all administrative
appeals, proceedings, hearings and conferences with the taxing authority in
respect of such claim and may, at its sole option, either direct Executive to
pay the tax claimed and sue for a refund or contest the claim in any permissible
manner, and Executive agrees to prosecute such contest to a

<PAGE>

determination before any administrative tribunal, in a court of initial
jurisdiction and in one or more appellate courts, as the Company shall
determine; provided, however, that if the Company directs Executive to pay such
claim and sue for a refund, the Company shall advance the amount of such payment
to Executive, on an interest-free basis and shall indemnify and hold Executive
harmless, on an after-tax basis, from any Excise Tax or income tax, including
interest or penalties with respect thereto, imposed with respect to such advance
or with respect to any imputed income with respect to such advance; and further
provided that any extension of the statute of limitations relating to payment of
taxes for Executive's taxable year with respect to which such contested amount
is claimed to be due is limited solely to such contested amount. Furthermore,
the Company's control of the contest shall be limited to issues with respect to
which a Gross-Up Payment would be payable hereunder and Executive shall be
entitled to settle or contest, as the case may be, any other issue raised by the
Internal Revenue Service or any other taxing authority.

     (e) If after the receipt by Executive of an amount advanced by the Company
pursuant to paragraph (d) of this Annex, Executive becomes entitled to receive
any refund with respect to such claim, Executive shall (subject to the Company's
complying with the requirements of paragraph (d) of this Annex) promptly pay to
the Company the amount of such refund (together with any interest paid or
credited thereon by the taxing authority after deducting any taxes applicable
thereto). If, after the receipt by Executive of an amount advanced by the
Company pursuant to paragraph (d) of this Annex, a determination is made that
Executive shall not be entitled to any refund with respect to such claim and the
Company does not notify Executive in writing of its intent to contest such
denial of refund prior to the expiration of 30-days after such determination,
then such advance shall be forgiven and shall not be required to be repaid and
the amount of such advance shall offset, to the extent thereof, the amount of
Gross-Up Payment required to be paid under paragraph (d) of this Annex. The
forgiveness of such advance shall be considered part of the Gross-Up Payment and
subject to gross-up for any taxes (including interest or penalties) associated
therewith.
