ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS

Disposal of Remainder of Healthcare Segment
(dollar amounts in millions)


On September 29, 1999, Bausch & Lomb Incorporated ("the company")
completed the sale of Charles River Laboratories (CRL), its
research laboratory animal and services business, to DLJ Merchant
Banking Partners II, L.P., an affiliate of the investment banking
firm of Donaldson, Lufkin & Jenrette, for approximately $400 in
cash and $43 in promissory notes pursuant to a Recapitalization
Agreement dated July 25, 1999 (the "Agreement"). Pursuant to the
Agreement, the company retained a 12.5% equity interest in CRL. A
copy of the Agreement is attached hereto in Exhibit 2(a).
Directors of the surviving CRL business after the sale, Charles
River Laboratories Holdings Inc., and Charles River Laboratories
Inc., include William H. Waltrip, a director of the company, and
Stephen C. McCluski, Senior Vice President and Chief Financial
Officer of the company.

On August 30, 1999 the company completed the sale of its Miracle-
Ear hearing aid business to Amplifon S.p.A., a privately held
Italian company. Its skin care business was divested in 1998
while the oral care and dental implant businesses were sold in
1996. These businesses, together with CRL, comprised the
company's healthcare segment.

CRL accounted for over 75% of the company's healthcare segment,
and its disposition constitutes a disposal of a business segment
as defined by Accounting Principles Board Opinion No. 30 (APB
30). APB 30 treatment was adopted for the second quarter of 1999
and as such, the company's Form 10-Q filed on August 10, 1999
excluded results of the healthcare segment from continuing
operations for both current and historical periods. This
treatment will continue for future filings.

In the second quarter of 1999, the company completed the sale of
its sunglass business, thus completing its exit from the eyewear
segment. As explained in the company's Current Report on Form 8-K
filed on July 12, 1999 (and which is herein incorporated by
reference), this exit from the sunglass business also constituted
the disposal of a business segment as defined by APB 30. APB 30
treatment was adopted for the second quarter of 1999 and as such,
the company's Form 10-Q filed on August 10, 1999 excluded results
of the eyewear segment from continuing operations for both
current and historical periods. This treatment will continue for
future filings.

                 PRO FORMA FINANCIAL INFORMATION
                           (UNAUDITED)

The following unaudited pro forma condensed consolidated balance
sheet and pro forma condensed consolidated statements of earnings
of Bausch & Lomb Incorporated have been prepared to illustrate
the effect of the divestiture of its research laboratory animal
and services business to DLJ Merchant Banking Partners II, L.P.,
and the sale of its hearing aid business to Amplifon, S.p.A.

The unaudited pro forma condensed consolidated balance sheet
assumes that the divestitures were consummated on June 26, 1999.
The unaudited pro forma condensed consolidated statements of
earnings assume that the divestitures were consummated as of
December 31, 1995. The pro forma adjustments, and the assumptions
on which they are based, are described in the accompanying
unaudited Notes to the Pro Forma Condensed Consolidated Financial
Statements. Certain pro forma adjustments related to the disposal
of the Eyewear segment are also described in the accompanying
unaudited Notes.

These pro forma financial statements are based upon, and should
be read in conjunction with, the historical consolidated
financial statements and the related notes, which were previously
reported on the company's 1996, 1997 and 1998 annual reports to
shareholders on Form 10-K and the company's quarterly report on
Form 10-Q for the quarter ended June 26, 1999, and which are
incorporated herein by reference.

The pro forma information is presented for illustrative purposes
only and is not necessarily indicative of operating results or
financial position that would have occurred if the divestitures
had been consummated on the dates indicated, nor is it
necessarily indicative of future operating results or financial
position.

                           (UNAUDITED)


Pro Forma Condensed Consolidated Balance Sheet Adjustments:

The unaudited pro forma condensed consolidated balance sheet
assumes that the divestiture of the healthcare segment occurred
as of June 26, 1999. The majority of the sunglass business was
disposed of on June 26, 1999. Assumptions and adjustments to
reflect the healthcare and eyewear segment disposals in the
condensed consolidated balance sheet include:

(a)  To reflect the estimated net cash proceeds and gain on the
sale of the healthcare segment:

Sales price                                                     $465.0
Estimated cash taxes                                             (82.7)
Estimated costs resulting directly from the divestiture
including transaction fees, legal and accounting fees, foreign
exchange losses related to a net investment hedge, and asset
write-offs                                                       (28.3)
Non-cash proceeds                                                (45.5)
Estimated net cash proceeds                                     $308.5
Net assets of healthcare segment as of June 26, 1999            (195.4)
12.5% cost based investment in CRL                                19.7
Non-cash proceeds                                                 45.5
Estimated after-tax gain                                        $178.3

For purposes of these pro forma statements, the company's
assumption of certain healthcare obligations have been included
in the estimated costs resulting directly from the sale of the
healthcare businesses. These include $4.1 in taxes payable and
$3.4 in accrued expenses.

In accordance with the Agreement, the company retains a 12.5%
cost based-investment in CRL.  For purposes of this statement the
company's remaining investment in CRL has been calculated based
on the net assets of CRL as of June 26, 1999.

(b)  To reflect the disposition of the June 26, 1999 net assets
held for disposal of the healthcare businesses.

(c)  The sale of sunglass business units in certain non-U.S.
locations has been deferred due to local regulatory and legal
considerations, all of which should be resolved to enable
closings to occur within 1-12 months of June 26, 1999. These pro
forma adjustments are to reflect the ultimate closings of these
locations.


Pro Forma Condensed Consolidated Statement of Earnings
Adjustments:

The unaudited pro forma condensed consolidated statements of
earnings assume that the divestiture of the eyewear and
healthcare segments occurred as of December 31, 1995, which was
the first day of fiscal 1996. The unaudited pro forma condensed
consolidated statements of earnings do not include any impact
from the gain on disposal or costs related to the divestitures.
The elimination of the eyewear and healthcare segment results of
operations in adjustment (d) includes all revenues and costs
reported historically by the divested businesses. Assumptions and
adjustments to reflect the segment disposals in the pro forma
condensed consolidated statements of income include:

 (d) To eliminate results of operations of the eyewear and
healthcare segments from historical financial statements. For
1999, no eliminations are needed since the statement of earnings
from continuing operations for the six months ended June 26, 1999
filed with Form 10-Q on August 10, 1999 excluded results of
operations for both the healthcare and eyewear segments as these
segments were reported as discontinued operations in the second
quarter of 1999. For 1998, amounts for eyewear relate entirely to
the sunglass product line while amounts reported in periods prior
to 1998 also include results of the previously divested thin film
technology business. For healthcare, all periods prior to 1999
include results for Charles River Laboratories, Miracle-Ear and
the skin care business which was sold during 1998. Adjustments in
1996 also reflect results of the divested oral care and dental
implant businesses, which were sold that year.

(e) To reflect the estimated impact on interest expense from use
of after-tax proceeds on the sale of the sunglass business which
reduces outstanding debt by $157.5 million. For purposes of these
statements, interest savings have been reflected using an average
rate of 5% per annum. A one-eighth of one percentage point change
in the interest rate used for pro forma purposes would have the
following impact on pro forma income from continuing operations:

                                                      Per
                                             Amount  Share
            Six months ended June 26, 1999   $   -    $  -
            Six months ended June 27, 1998       -       -
            Year ended December 26, 1998       0.1       -
            Year ended December 27, 1997       0.1       -
            Year ended December 26, 1996       0.1       -

Debt was not reduced as a result of the divestitures of CRL and
Miracle-Ear, thus yielding no reduction in interest expense for
any of the periods presented.

(f) To eliminate a fourth quarter 1998 impairment charge of $85
or $1.51 per share, with no associated tax benefit, related to
the goodwill acquired as part of the Miracle Ear hearing aid
business.

(g) To eliminate a pre-tax gain of $56 ($33 or $0.59 per share
after tax) resulting from the sale the skin care business.

fees in connection with the transactions contemplated hereby or
thereby.

     4.6  Financing

complete copies of the Commitment Letters.  As of the date of
this Agreement, the Commitment Letters are in full force and
effect and have not been rescinded, amended or modified in any
respect.

     .  In connection with the negotiation and execution of this
Agreement, Buyer's Group has performed a comprehensive
investigation of the CRL Business and, with its advisors, has
made its own analysis and evaluation of the CRL Business, the
Purchased Shares and Assumed Liabilities and has received from
Seller Parent or its Affiliates or had access to all information
that Buyer or Buyer Parent deems necessary or desirable in
deciding whether to acquire the Purchased Shares.  Buyer's Group
has had the opportunity to ask questions of and receive answers
from officers and other representatives of Seller Parent, Recap

and conditions of its acquisition of the Purchased Shares.  In
entering into this Agreement, Buyer's Group has relied solely
upon its own investigation and analysis and the representations,

delivered pursuant hereto.  Buyer, by reason of its business or
financial experience, or the business and financial experience of
its professional advisors has the capacity to evaluate and
protect its own interests in the acquisition of the Purchased
Shares.  Buyer, and each of its equity owners, has the financial
capacity to bear the risk of, including the entire loss of, its
investment in the Purchased Shares.  Nothing contained in this
Section 4.7 shall prohibit or in any way limit Buyer and Buyer
Parent from relying upon the representations and warranties of
Seller Parent contained in Article 3 nor from being indemnified
pursuant to Article 8.

     .  Except for the representations and warranties contained
in this Article 4 or in any certificates or other documents
executed by Buyer or Buyer Parent in connection with the
transactions contemplated by this Agreement, neither Buyer, Buyer
Parent nor any other Person makes any express or implied
representation or warranty on behalf of Buyer or Buyer Parent.

approval or authorization is sought, participate, directly or
through its Representatives, in the process of obtaining such
consents, approvals and authorizations.  The forms, terms and
conditions of such consents, approvals and authorizations shall
be subject to the prior approval of Buyer, which shall not be
unreasonably withheld or delayed.

     5.5  Tax Matters.

     5.5.1     Seller Parent shall cause the CRL Business, Recap
Subco and the Recap Subsidiaries to be included in the
consolidated federal income Tax Returns of Seller Parent for any
periods for which it is required to be so included, and in any
other required state, local and foreign consolidated, affiliated,
combined, unitary or other similar group income Tax Returns that
include the CRL Business, for all periods ending on or prior to
the Closing Date.  Seller Parent shall prepare information
(including schedules, worksheets and other data) necessary, in
Seller Parent's judgment, to include the CRL Business, Recap
Subco and the Recap Subsidiaries in such income Tax Returns for
such periods.  Seller Parent shall timely prepare and file, or
cause to be prepared and filed, all income Tax Returns of or
including the CRL Business, Recap Subco and the Recap

Closing Date and shall pay, or cause to be paid, when due all
income Taxes relating to such Tax Returns.

     5.5.2     (a)  Seller Parent shall have the right and
obligation to represent the interests of the CRL Business, Recap
Subco or the Recap Subsidiaries in any Tax audit or
administrative or court proceeding relating to Tax Returns for
any periods or portions thereof ending on or prior to the Closing
Date.

     (b)  Following the Closing, in the event of an audit of
Recap Subco or any Recap Subsidiary as referred to in
Section 5.5.3, Buyer shall execute, or cause the appropriate
Affiliate of Buyer to execute, a federal tax Form 2848 or
comparable Power of Attorney authorizing Seller Parent or Seller
Parent's designated representative to represent Recap Co or such
Recap Subsidiary with respect to income Taxes for which Seller
Parent may be liable pursuant to this Section 5.5 or Article 8.

     5.5.3     Buyer shall promptly notify Seller Parent in
writing upon receipt by Buyer or any Affiliate of Buyer of notice
of any pending or threatened Tax audits or assessments of the CRL
Business, Recap Subco or the Recap Subsidiaries so long as any

to the Knowledge of Buyer.

     5.5.4     After the Closing Date, Buyer and Seller Parent
shall provide each other with such cooperation and information
relating to the CRL Business, Recap Subco or the Recap
Subsidiaries as either party reasonably may request in filing any
Tax Return (or amended Tax Return) or refund claim, determining
any Tax liability or a right to a refund, conducting or defending
any audit or other proceeding in respect of Taxes or effectuating
the terms of this Agreement.  The parties shall retain all Tax
Returns, schedules, work papers and other material documents
relating thereto, until the seventh anniversary of the Closing
Date or, if later, the expiration of any relevant statute of
limitations (and, to the extent notified by any party, any
extensions thereof) and, unless such Tax Returns and other
documents are offered and delivered to Seller Parent or Buyer, as
applicable, until the final determination of any Tax in respect
of such years.  Any information obtained under this Section 5.5.4
shall be kept confidential, except as may be otherwise necessary
in connection with filing any Tax Return (or amended Tax Return)
or refund claim, determining any Tax liability or a right to a
refund, conducting or defending any audit or other proceeding in
respect of Taxes or otherwise effectuating the terms of this
Agreement.  Notwithstanding the foregoing, neither Seller Parent
nor Buyer, nor any of their Affiliates, shall be required
unreasonably to prepare any document, or determine any
information not then in its possession, in response to a request
under this Subsection 5.5.4; provided, however, no request shall
be deemed unreasonable if made in response to the request of a
taxing authority for information or documents not in the
possession of the party receiving the request nor otherwise
reasonably available to it.

     5.5.5     CRL will join with Buyer in making a timely
election under Section 338(h)(10) of the Code (the
"Section 338(h)(10) Election") to treat the Merger as the deemed
sale of the assets of all or some (as elected by Buyer) of Recap
Co and the Recap Subsidiaries while such Persons are members of
Seller Parent's consolidated group for federal income tax
purposes.  If requested by Buyer, CRL (unless there is a material
detriment to CRL) will also join with Buyer in making any similar
election under state or local law, which if made shall be treated
as part of the Section 338(h)(10) Election.  In order to effect a
timely Section 338(h)(10) Election, at the Closing, each of CRL
and Buyer shall jointly prepare and execute copies of IRS Form
8023 and all attachments required to be filed therewith in
accordance with the Code and the applicable regulations
thereunder, which Form 8023 shall be completed by them to the
extent practicable at the time of the Closing in a manner
consistent with the parties' agreement as to the allocation of
the "MADSP" among the assets of Recap Co and the Recap
Subsidiaries as set forth in Schedule 5.5.5 of the Disclosure
Schedule and shall be delivered to Buyer at the Closing.
Following the Closing, Buyer will complete the Form 8023 and will
adjust any allocation to comply with the requirements of
Section 33 8(h)(10) of the Code and in a manner consistent with
provisions of Schedule 5.5.5 of the Disclosure Schedule, and will
file the Form 8023 with the IRS (and any applicable state or
local tax authority) with a copy to CRL in order to effect a
timely Section 338(h)(10) Election.  CRL and Buyer agree
otherwise to take all necessary action to make a timely
Section 338(h)(10) Election with respect to the Merger, and shall
otherwise cooperate fully with each other in the making of such
election and to comply with all substantive and procedural
requirements of Section 338(h)(10) of the Code, any applicable
regulations thereunder and any applicable provision of state or
local law.  Except as required by applicable Law, neither CRL nor
Buyer will take, nor permit any Affiliate to take, for federal,
state or local income Tax purposes, any position inconsistent
with the Section 338(h)(10) Election or the allocation set forth
in the Form 8023 filed by Buyer.  Buyer will make a timely
election under Section 338(g) of the Code with respect to any
Recap Subsidiary which is incorporated in a jurisdiction other
than the United States and shall comply with all substantive and
procedural requirements of Section 338(g) of the Code and any
applicable regulations thereunder, unless Buyer would suffer a
material detriment as a result of making such election.

     5.6  Employee Matters.

     5.6.1     During the period commencing on the Closing Date
and ending on the eighteen (18) month anniversary of the Closing
Date, Buyer shall, or shall cause Recap Subco and the Recap
Subsidiaries to provide employee benefit plans, programs and
arrangements having benefits not less favorable in the aggregate
to the Employees of Recap Subco and the Recap Subsidiaries than
the Benefit Plans and Non-U.S. Benefit Plans, as applicable,
provided that nothing in this Agreement shall require Buyer,
Recap Subco or any Recap Subsidiary to establish, provide,
sponsor or maintain any specific plan, program or arrangement or
shall require any such Person to continue the employment, or to
refrain from modifying or terminating the terms of employment of
any Employee.  In the case of any new plan, program or
arrangement, Buyer shall, or shall cause Recap Subco and the
Recap Subsidiaries to the extent permitted under applicable Law,
provide that periods of service with any of Recap Subco any Recap
Subsidiary, any Seller or any Affiliate of any of the foregoing
Persons prior to the Closing Date shall be credited for
eligibility, vesting and benefits purposes (if applicable and
without duplication) with respect to such plan, program or
arrangement, provided that no service will be credited for
purposes of calculating an employee's benefit accrual under any
Defined Benefit Plan or any Non-U.S. Benefit Plan that is a
defined benefit plan for any period of time that the employee did
not participate in such plan on or before the Closing Date.

     5.6.2     For any mass layoff or plant closing which occurs

Notification Act or any similar federal, state, local or foreign
Law.

     5.6.3     On the Closing Date, Buyer shall have in effect

former employees of Recap Subco, Recap Subsidiaries and/or their
predecessors and such individuals' qualifying beneficiaries who
are eligible for such coverage.

     5.6.5     On the Closing Date, Seller Parent shall pay and
discharge in full all Excluded Debt other than Excluded Debt with
respect to Joint Ventures and terminate all related liens,

their respective obligations under the Releases.

     5.7  Additional Assurances.

     5.7.1     After the Closing Date, Seller Parent shall
promptly and shall cause its Affiliates promptly to, and Buyer
shall promptly and shall cause Recap Co and the Recap
Subsidiaries promptly to, take such additional actions and
execute any such additional documents and instruments as may be
reasonably necessary (i) to effectuate the transactions
contemplated by this Agreement, including to fully vest good and
valid title to all of the CRL Business Assets in Recap Subco and
the Recap Subsidiaries, as applicable, and to fully vest good and
valid title in the Excluded Assets in Seller Parent or its
Affiliates free and clear of all liens, claims or other

Liabilities not retained or assumed by Seller Parent or an
Affiliate prior to or on the Closing Date, or to cause Recap
Subco or any Recap Subsidiary to assume any Assumed Liability not

after the Closing Date, Seller Parent agrees to assist Buyer in
any reasonable manner requested, and without unreasonable delay,
in the preparation of financial statements of the CRL Business,
including the interim unaudited financial statements at and for
the three months ended March 27, 1999 and at and for nine months
ended September 25, 1999, including so that such financial
statements can be presented in conformity with the accounting
rules of Regulation S-X under the Securities Act of 1933, as
amended; provided however, that Buyer shall bear any out-of-
pocket costs and expenses incurred by Seller Parent or any of its
Affiliates in connection with providing such assistance.

     5.7.2     Notwithstanding anything to the contrary contained
in this Agreement, to the extent that the sale, assignment,
transfer, conveyance or delivery or attempted sale, assignment,
transfer, conveyance or delivery of any CRL Business Asset in the
Internal Reorganization or any transaction contemplated by this
Agreement is prohibited by any applicable Law or would require
any Governmental Entity or other third party authorizations,
approvals, consents or waivers and such authorizations,
approvals, consents or waivers shall not have been obtained prior
to the Closing and either such item(s) are not a condition to
Closing or Buyer shall have waived in writing the applicable
condition to Closing with respect to such item(s), this Agreement
shall not constitute a sale, assignment, transfer, conveyance or
delivery, or any attempted sale, assignment, transfer, conveyance
or delivery thereof.  Following the Closing, the parties shall
use Commercial Efforts and shall cooperate with each other to
obtain promptly such authorizations, approvals, consents or
waivers.  Pending such authorization, approval, consent or
waiver, the parties shall cooperate with each other in any
reasonable and lawful arrangements designed to provide to Buyer,
Recap Co and the Recap Subsidiaries the benefits and liabilities
of use of such CRL Business Asset.  Once such authorization,
approval, consent or waiver for the sale, assignment, transfer,
conveyance or delivery of a CRL Business Asset not sold,
assigned, transferred, conveyed or delivered at the Closing is
obtained, Seller Parent shall and shall cause its Affiliates to
promptly assign, transfer, convey and deliver, or cause to be
assigned, transferred, conveyed and delivered, such CRL Business
Asset to Recap Subco or a Recap Subsidiary for no additional
consideration free and clear of all liens, claims or other
encumbrances except Permitted Encumbrances.  To the extent that
any such CRL Business Asset cannot be transferred or the full
benefits and liabilities of use of any such CRL Business Asset
cannot be provided to Buyer, Recap Subco and the Recap
Subsidiaries following the Closing pursuant to this Section 5.7,
then Buyer and Seller Parent or one or more of its Affiliates
shall enter into such arrangements (including subleasing or
subcontracting if permitted) designed to provide to Recap Subco
and the Recap Subsidiaries the economic and operational
equivalent of obtaining such authorization, approval, consent or
waiver and the performance by Recap Subco and the Recap
Subsidiaries of the obligations thereunder to the extent
permitted by Law.

     5.7.3     Subject to Section 5.4, Buyer and Seller Parent
shall cooperate with each other and use their Commercial Efforts,
as soon as practicable after the Closing, to take all actions, if
any are required, to transfer all permits, authorizations and
registrations issued to the CRL Business.

     .  Seller Parent shall prepare and deliver to Buyer at least
five (5) Business Days prior to the Closing an update of the

disclosure as of the date of this Agreement (an "Update").  In
the event of the delivery to Buyer of an Update which sets forth
the occurrence or existence of an event or other matter which

to be satisfied (determined without regard to the Update), Buyer
shall have no obligation to complete the Closing of the
transactions contemplated by this Agreement and may terminate
this Agreement pursuant to and in accordance with the procedure
set forth in Section 7.1.1(d) (without regard to the twenty (20)
day cure period); provided that in the event that Buyer does not
so terminate this Agreement and the Closing occurs, the
Disclosure Schedule shall be deemed to be amended as of the date
of this Agreement to include the events or other matters set
forth in the Update for all purposes of this Agreement, including
Article 8.

Recap Co Common Stock, Buyer shall cause Recap Co and the Recap
Subsidiaries to procure and maintain in full force and effect
insurance coverage in such amounts, covering such risks and
liabilities and with such deductibles or self-insured retentions
as is the normal industry practice for businesses of similar size
operating in similar industries and markets and with similar

Acquisition Proposal or any request for nonpublic information
relating to the CRL Business or for access to the employees,
properties, books or records of the CRL Business by any Person
who indicates that they may be considering making, or has made, a
Company Acquisition Proposal, Seller Parent shall notify Buyer of
the fact that such event has occurred and shall notify Buyer of
the Person if the Company Acquisition Proposal is received,
directly or indirectly, by any Person identified on Schedule 5.11
hereto.  For the purposes hereof, "Company Acquisition Proposal"
shall mean any offer or proposal for (whether oral or in
writing), or any indication of interest in, a merger or other
business combination involving any of the CRL Business, Recap
Subco or any Recap Subsidiary or any Seller or the acquisition of
any equity interest in, or all or a substantial portion of the
assets of, any of Recap Subco, any Recap Subsidiary or any Seller
or the CRL Business, other than the transactions contemplated by
this Agreement and other than transactions with respect to the
Excluded Assets.

     5.12 Books and Records

     .  Seller Parent shall retain in accordance with its current
records retention polices all books and records relating to the
CRL Business and, unless otherwise consented to in writing by
Seller Parent or Buyer (as the case may be), Buyer and Seller

Date, destroy, alter, or otherwise dispose of any of such books
and records without first offering to surrender to Seller Parent
or Buyer, as the case may be, such books and records or any
portion thereof which Buyer or Seller Parent, as the case may be,
may intend to destroy, alter, or dispose.  Buyer and Seller
Parent will allow the other party's representatives access to
such books and records, upon reasonable request during such
party's normal business hours, for the purpose of examining and
copying the same (but only to the extent they relate to the CRL
Business) in connection with any matter related to or arising out
of this Agreement or the transactions contemplated hereby or the
conduct by Buyer of the CRL Business.

neither it nor any of its Affiliates shall make any commercial
use of the Names from and after the Closing Date; provided,
however, Seller Parent shall retain the right to make use of the
Names for purposes of reflecting its ownership of the CRL
Business prior to the Closing Date.  On the Closing Date, Seller

contains the words "Charles River" or "SPAFAS" to be changed to a
name that does not contain such words.

shall be decreased to the extent of any insurance proceeds (net
of all Costs payable in connection therewith) actually received
by a Buyer Indemnified Party or Seller Indemnified Party or which
a Buyer Indemnified Party or a Seller Indemnified Party is
unconditionally entitled to receive in respect of the Loss giving
rise to such indemnity payment.

     8.4.4     The indemnifying party under Sections 8.2(a) and
8.3(a) shall not be liable to any Indemnified Party with respect
to any occurrence, event, circumstance, act, omission or conduct
unless such matter or a series of related matters arising from
the same or similar occurrences, events, circumstances, acts,
omissions or conduct which causes a representation or warranty
under Sections 8.2(a) or 8.3(a) to be breached results in Costs
of $25,000 or more, and then only for the amount of such excess.

     8.4.5     Each indemnified party shall be obligated, in
connection with any claim for indemnification under Section 8.2
or 8.3, to use Commercial Efforts to mitigate Losses upon and
after becoming aware of any event which could reasonably be
expected to give rise to such Losses.

     8.5  Procedure

     .  Promptly after acquiring knowledge of any Loss, or any
action, suit, investigation, proceeding, demand, assessment,
audit, judgment, or claim ("Claim") which may result in a Loss or
Litigation Expense, the Person seeking indemnity under this
Article 8 (the "Indemnitee") shall give written notice thereof to
the party from whom indemnity is sought (the "Indemnitor");
provided, however, that the failure to promptly notify the
Indemnitor shall not affect the indemnification obligation
hereunder if the Indemnitor was not prejudiced thereby and the
failure to promptly notify was inadvertent.  The Indemnitor shall
have the right, at its expense, to defend or contest (subject to
the third to last sentence of this Section 8.5) such Claim,
through counsel of its choice (unless such Indemnitor is relieved
of its liability hereunder with respect to such Claim and Loss
and Litigation Expense by the Indemnitee) and shall not then be
liable for fees or expenses of the Indemnitee's attorneys (unless
the Indemnitor and Indemnitee are parties to the action and there
exists a conflict of interest between the Indemnitor and the
Indemnitee, in which event the Indemnitor will be responsible for
the reasonable fees and expenses of one firm of counsel for all
Indemnitees), and the Indemnitee and the Indemnitor shall provide
to each other all necessary and reasonable cooperation in the
defense of all Claims, including, but not limited to, reasonable
access to employees who are familiar with the transactions out of
which such Claim or Loss may have arisen.  In the event that the
Indemnitor shall undertake to defend any Claim, it shall promptly
notify the Indemnitee of its intention to do so within thirty
(30) days of being notified of any such Claim.  In the event that
the Indemnitor, after written notice from Indemnitee, fails to
take timely action to defend the same, the Indemnitee shall have
the right to defend the same by counsel of its own choosing, but
at the cost and expense of the Indemnitor, provided no settlement
of a Claim by Indemnitee (other than a Claim relating to an
Excluded Liability) shall be effected without the consent of the
Indemnitor which shall not be unreasonably withheld or delayed
unless Indemnitee waives any right to indemnification therefor.
The Indemnitor may settle or compromise any Claim without the
prior written consent of Indemnitee except for settlement or
compromise of a Claim (i) which includes the unconditional
release by the Person asserting the Claim and any related
claimants of Indemnitee from all liability with respect to such
Claim in form and substance reasonably satisfactory to
Indemnitee, (ii) which would not adversely affect the Indemnitee
and its Affiliates to own, hold, use and operate their respective
assets and businesses, and (iii) for money damages only.  Seller
Parent and Buyer shall treat any payment under this Article 8 for
all Tax purposes as an adjustment of the Purchase Price and as
allocable to the assets deemed purchased under the
Section 338(h)(10) Election as shall reasonably be determined by
the Indemnitee, except to the extent such treatment is not
permitted under applicable Law.

     8.5.1     (a)  The amount of any indemnification payment
otherwise determined to be due under this Article 8 shall be
reduced (but not increased) by the amount of the "Actual Tax
Savings" (as hereinafter defined), if any, realized by the
Indemnitee with respect to the indemnified Loss.  For purposes
hereof, the amount of an Indemnitee's Actual Tax Savings shall be
equal to the excess, if any, of the Actual Tax Benefit Amount
over the Actual Tax Detriment Amount, each as defined below and
each of which shall be calculated taking into account only those
items of tax savings or tax liabilities actually incurred by the
Indemnitee in the taxable year in which the indemnification
payment is made (taking into account all of the indemnitee's tax
attributes for the period or periods in question).

          (b)  The Actual Tax Benefit Amount shall equal the
actual amount of any reduction of the Indemnitee's federal, state
or local (but not foreign) income tax liability for the taxable
year in which the indemnification payment is made, which
reduction would not have been realized but for the occurrence of
the event in respect of which the indemnification payment is made
or the receipt of the indemnification payment.  The Actual Tax
Detriment Amount shall equal the actual amount of any increase in
the Indemnitee's federal, state or local (but not foreign) income
tax liability for the taxable year in which the indemnification
payment is made, which increase would not have been realized but
for the occurrence of the event in respect of which the
indemnification payment is made or the receipt of the
indemnification payment.

          (c)  The parties agree that any determination made
under this Section 8.5.1 shall be made by the Indemnitee, who
shall provide the Indemnitor with its calculation of the Actual
Tax Savings in writing.  The parties shall attempt to resolve any
dispute over such determination in good faith, provided that if
such dispute is not resolved by the parties such determination
shall be made by the national accounting firm regularly employed
by the Indemnitee.

     8.6  No Consequential Damages

     .  NEITHER ANY PARTY TO THIS AGREEMENT NOR THEIR AFFILIATES
SHALL BE LIABLE FOR CONSEQUENTIAL DAMAGES SUFFERED BY A PARTY OR
ITS AFFILIATES WITH RESPECT TO ANY TERM OR THE SUBJECT MATTER OF
THIS AGREEMENT; PROVIDED, HOWEVER, THAT THIS WAIVER SHALL NOT
LIMIT ANY LIABILITY OF ANY PARTY TO INDEMNIFY THE APPLICABLE
INDEMNIFIED PARTIES FOR LOSS OR LITIGATION EXPENSES ARISING FROM
COSTS OF SUCH TYPE WHICH THE INDEMNIFIED PARTY IS REQUIRED TO PAY
TO ANY OTHER PERSON.

     8.7  Exclusive Remedy

     .  If the Closing occurs, the exclusive remedies for any
breach of any representation, warranty, covenant or agreement
hereunder shall be the indemnification provided by this
Article 8, and each party expressly waives any other rights or
remedies it may have, whether under this Agreement or otherwise,
or (other than in the case of fraudulent conduct) at law or in
equity, provided, however, that equitable relief, including the
remedies of specific performance and injunction shall be
available with respect to any actual or attempted breach of this
Agreement occurring before the Closing Date or with respect to
the breach of any covenant to be performed after the Closing
Date.

     8.8  Validity

     .  The indemnification agreements provided for in this
Article 8 shall apply notwithstanding any knowledge of, or any
investigation made at any time by or on behalf of, any party
hereto.

     8.9  Waiver

     .  It is understood and agreed that neither Seller Parent
nor any Seller shall be entitled to any indemnification, right of
contribution or other right of recovery from Recap Co, Recap
Subco or any Recap Subsidiary in connection with any claim made
by any Buyer Indemnification Party(s) against Seller Parent
hereunder, all of which are hereby irrevocably and
unconditionally waived and released by Seller Parent and each
Seller; provided, however, such waiver shall not preclude Seller
Parent or any Seller from contesting any such claims made by any
Buyer Indemnified Party, including, without limitation, on the
basis that the alleged Loss or Litigation Expense arose, in whole
or in part, as a result of the operation of the CRL Business
after the Closing Date or arose out of an Assumed Liability.

                            ARTICLE 9

the prior consent of the other parties (which consent shall not
be unreasonably withheld, conditioned or delayed) unless such
release or announcement is required by applicable Laws or
pursuant to any applicable listing agreement with, or rules or
regulations of, the NYSE, in which case the disclosing party,
prior to making such announcement, shall consult with the other
parties.  In the event the transactions contemplated by this

other all documents, work papers and other materials, including
any extracts, summaries, analyses, compilations or other

from such information (including any copies thereof whether in
written, electronic or other format) or destroy such materials
and provide to the other a written certification of such
destruction and will hold in absolute confidence any information
obtained from the other party except to the extent (i) such party
is required to disclose such information by Law or such
disclosure is necessary or desirable in connection with the
pursuit or defense of a claim relating to the transactions
contemplated hereby, (ii) such information was known by such
party prior to such disclosure or was thereafter developed or
obtained by such party independent of such disclosure, or
(iii) such information becomes generally available to the public
or is otherwise no longer confidential.  Prior to any disclosure
of information pursuant to the exception in clause (i) of the
preceding sentence, the party intending to disclose the same
shall so notify the party that provided the same in order that
such party may seek a protective order or other appropriate
remedy should it choose to do so.

by Seller Parent, the second $100,000 shall be paid by, and all
amounts in excess of $200,000 shall be paid 50% by Recap Co and

applicable Law or custom to file such Transfer Tax Returns.  The
filing party shall promptly provide the other applicable parties
with copies of such Transfer Tax Returns.  All Transfer Tax

accordance with the provisions of this Section 9.3.  Seller
Parent shall pay all interest or penalty charges associated with
Seller Parent's failure to pay when due any Transfer Taxes or any
Reorganization Transfer Taxes, provided that such failure is not

including without limitation, any investigation by or on behalf
of any party, shall be deemed to constitute a waiver by the party
taking such action of compliance with any representations,
warranties, covenants or agreements contained herein or in any
other document delivered in connection herewith.  The waiver by
any party hereto of a breach of any provision of this Agreement
shall not operate or be construed as a waiver of any subsequent
breach.  No failure on the part of any party hereto to exercise,
and no delay in exercising, any right hereunder shall operate as
a waiver thereof.

consent to submit to the exclusive jurisdiction of the federal

of any Company Securities) except in compliance with the
Securities Act and the terms and conditions of this Agreement.

Any attempt to transfer any Company Securities not in compliance
with this Agreement shall be null and void and the Company shall
not, and shall cause any transfer agent not to, give any effect
in the Company's stock records to such attempted transfer.

No transferee other than a Permitted Transferee or a party hereto
shall be required or permitted to become a party to this
Agreement or have the benefit of any rights hereunder or the
burden of any obligations hereunder.

Except as set forth in the first paragraph of this Section 3.01,
transfers by the LLC are not subject to any restrictions.


SECTION 3.02. Legends. In addition to any other legend that may
be required, each certificate for shares of Common Stock and each

substantially the following form:

"THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES
LAWS AND MAY NOT BE OFFERED OR SOLD EXCEPT IN COMPLIANCE
THEREWITH. THIS SECURITY IS ALSO SUBJECT TO ADDITIONAL
RESTRICTIONS ON TRANSFER AS SET FORTH IN THE INVESTORS'
AGREEMENT DATED AS OF SEPTEMBER 29, 1999, COPIES OF WHICH

<Page 11>
MAY BE OBTAINED UPON REQUEST FROM CHARLES RIVER
LABORATORIES HOLDINGS, INC. OR ANY SUCCESSOR THERETO."

If any Company Securities shall cease to be Registrable
Securities under clause (i) or clause (ii) of the definition
thereof, the Company shall, upon the written request of the
holder thereof, issue to such holder a new certificate evidencing
such securities without the first sentence of the legend required
by this Section endorsed thereon. If any Company Securities cease
to be subject to any and all restrictions on transfer set forth
in this Agreement, the Company shall, upon the written request of
the holder thereof, issue to such holder a new certificate
evidencing such Company Securities without the second sentence of
the legend required by this Section endorsed thereon.

SECTION 3.03. Permitted Transferees. Notwithstanding anything in
this Agreement to the contrary, any Stockholder may at any time
transfer any or all of its Company Securities to one or more of
its Permitted Transferees without the consent of the Board or any
other Stockholder or group of Stockholders and without compliance
with Sections 3.04, 3.05, 3.06 and 4.01 so long as (a) such

the terms of this Agreement and (b) the transfer to such
Permitted Transferee is not in violation of applicable federal or
state securities laws.

SECTION 3.04. Restrictions on Transfers by Management

(ii) subject to the Public Offering Limitations, in a Public
Offering in connection with the exercise of its rights under
Article 5 hereof;

(iii) after the Initial Public Offering, pursuant to the
exemption from registration provided under Rule 144, provided
that until the later of (A) the third anniversary of the IPO and
(B) the Restriction Termination Date, such sales cannot reduce
the Stockholder's ownership to (or occur at a time when such
Stockholder's ownership is otherwise) below the greater of (X)
50% of his or her Initial Ownership and (Y) that percentage of
his or her Initial Ownership as equals the percentage of the
LLC's Initial Ownership remaining after previous dispositions by
the LLC; or

<Page 12>
(iv) following the Restriction Termination Date, to (A) any Third
Party other than an Adverse Person or any person deemed
inappropriate by the Board or (B) any Third Party through a
national securities exchange, in each case for consideration
consisting solely of cash, provided, however, that the amount
sold in any 12-month period may not exceed 20% of the Management
Stockholder's Initial Ownership.

For purposes of this Agreement, "Public Offering Limitations"
means (A) no Management Stockholder shall be permitted to sell
any Shares in the Initial Public Offering, (B) in the first
public offering following the Initial Public Offering, no
Management Stockholder may sell more than the lesser of (x) 50%
of his or her Pro Rata Portion and (y) 20% of his or her holdings

each Management Stockholder may sell no more than the lesser of
(x) his or her Pro Rata Portion and (y) 50% of his or her

Notwithstanding the foregoing sentence, the provisions of Section
3.04(a) shall not terminate with respect to any Management
Stockholder's Shares which shall have been pledged to the Company
as security in connection with any indebtedness for borrowed
money owed by such Management Stockholder to the Company unless
the proceeds from the sale of such Shares are applied to repay
such indebtedness in full.

(iv) following the Restriction Termination Date, to (A) any Third
Party other than an Adverse Person or any person deemed
inappropriate by

the Board or (B) any Third Party through a national securities
exchange, in each case for consideration consisting solely of
cash.

transferor shall first have complied with Section 3.06(b).

(b) Right of First Refusal.

(i) If a New Minority Shareholder proposes to transfer Company
Securities owned by such New Minority Shareholder in a
transaction pursuant to Section 3.06(a)(iv), such New Minority
Shareholder shall provide DLJ Merchant Banking II, Inc. and the
Company written notice of such proposed transfer. The notice
shall identify the number of Company Securities proposed to be
transferred, the cash price at which a transfer is proposed to be
made and all other material terms and conditions of the offer.

(ii) The receipt of a such notice by DLJ Merchant Banking II,
Inc. and the Company from a New Minority Shareholder shall
constitute an offer by such New Minority Shareholder to sell
first, to the DLJ Entities and, if not accepted or only accepted
in part by the DLJ Entities, second to the Company, for cash, the
Company Securities at the price and on the

<Page 14>
other terms and conditions set forth in such notice. Such offer
shall be irrevocable for 10 Business Days after receipt of such
notice by the DLJ Entities and the Company. During such period,
any of the DLJ Entities and the Company shall have the right to
accept such offer as to all or a portion of the Company
Securities (provided that first priority of the right to accept
is given to the DLJ Entities; and provided further that the
aggregate number of Company Securities accepted by the DLJ
Entities and the Company together equals the total number of
Company Securities subject to the offer) by giving a written
notice of acceptance to such Ne Minority Shareholder prior to the
expiration of the offer period.

(iii) Any Person who has accepted the offer shall purchase and
pay for all Company Securities accepted within 30 days after such
acceptance.

(iv) Upon the failure to accept the offer in full prior to the
expiration of the offer period or the failure to consummate the
purchase within 30 days after the acceptance of the offer, there
shall commence a 60-day period during which the New Minority
Shareholder that gave the notice shall have the right to transfer
to a third party any or all of the Company Securities subject to
such offer at a price in cash not less than 90% of the price
indicated in the applicable notice to DLJ Merchant Banking II,
Inc. and the Company, and on the other terms and conditions set
forth therein, provided that the transfer to such third party is
not in violation of applicable federal or state or foreign
securities laws. If such New Minority Shareholder does not
consummate the sale in accordance with the foregoing time
limitations, such New Minority Shareholder may not thereafter
transfer any Company Securities in a transaction pursuant to
Section 3.06(a)(iv) without repeating the foregoing procedures.

(c) The provisions of Section 3.06(a) shall terminate upon the
earliest to occur of (i) the tenth anniversary of the Closing
Date and (ii) the date upon which the shareholdings of the LLC
fall below 10% of its Initial Ownership.


ARTICLE 4
TAG-ALONG RIGHTS; DRAG-ALONG RIGHTS

SECTION 4.01. Rights to Participate in Transfer. (a) If the LLC
(the "Selling Person") proposes to transfer a number of Shares
equal to or exceeding 25% of the outstanding Shares in a single
transaction or in a series of related transactions on the date of
the proposed sale (a "Tag-Along Sale"), the Other

<Page 15>
Stockholders may, at their option, elect to exercise their rights
under this Section 4.01 (each such Stockholder, a "Tagging
Person"), provided that no such rights shall apply to transfers
of Shares (i) in a Public Offering or pursuant to Rule 144
(defined for these purposes to exclude Rule 144A under the
Securities Act), (ii) to any Permitted Transferee of the LLC
(defined for these purposes to exclude, except in the case of a
general distribution to DLJ Partners, any Permitted Transferee
who is a Permitted Transferee solely by reason of being an
Affiliate of a DLJ Partner), or (iii) to holders of limited
liability company units in the LLC ("Units"). In the event of
such a proposed transfer, the Selling Person shall provide each
Other Stockholder written notice of the terms and conditions of
such proposed transfer ("Tag-Along Notice") and offer each
Tagging Person the opportunity to participate in such sale. The
Tag-Along Notice shall identify the number and type of Company
Securities subject to the offer ("Tag-Along Offer"), the cash
price at which the transfer is proposed to be made, and all other
material terms and conditions of the Tag-Along Offer, including
the form of the proposed agreement, if any. From the date of the
Tag-Along Notice, each Tagging Person shall have the right (a
"Tag-Along Right"), exercisable by written notice ("Section 4.01
Response Notice") given to the Selling Person within 15 Business
Days (the "Tag-Along Notice Period"), to request that the Selling
Person include in the proposed transfer the number of Company
Securities held by such Tagging Person as is specified in such
notice; provided that if the aggregate number of Company
Securities proposed to be sold by the Selling Person and all
Tagging Persons in such transaction exceeds the number of Company
Securities which can be sold on the terms and conditions set
forth in the Tag-Along Notice, then only the Tag-Along Portion of
Company Securities of each Tagging Person shall be sold pursuant
to the Tag-Along Offer and the Selling Person shall sell its Tag-
Along Portion of Company Securities and such additional Company
Securities as permitted by Section 4.01(d). If the Tagging
Persons exercise their Tag-Along Rights hereunder, each Tagging
Person shall deliver, together with its Section 4.01 Response
Notice, to the Selling Person the certificate or certificates
representing the Company Securities of such Tagging Person to be
included in the transfer, together with a limited power-of-
attorney authorizing the Selling Person to transfer such
Securities on the terms set forth in the Tag-Along Notice.
Delivery of such certificate or certificates representing the
Company Securities to be transferred and the limited power-of-
attorney authorizing the Selling Person to transfer such Company
Securities shall constitute an irrevocable acceptance of the Tag-
Along Offer by such Tagging Persons. If, at the end of a 120 day
period after such delivery, the Selling Person has not completed
the transfer of all such Company Securities on substantially the
same terms and conditions set forth in the Tag-Along Notice
(provided, however, that the cash price payable in any such sale
may exceed the cash price specified in the Tag-Along Notice by up
to 10%), the Selling Person shall return to each Tagging Person
the limited power-of-attorney (and all copies thereof) together

<Page 16>
with all certificates representing the Company Securities which
such Tagging
Person delivered for transfer pursuant to this Section 4.01.

(b) Concurrently with the consummation of the Tag-Along Sale, the
Selling Person shall notify the Tagging Persons thereof, shall
remit to the Tagging Persons the total consideration (by bank or
certified check) for the Company Securities of the Tagging
Persons transferred pursuant thereto, and shall, promptly after
the consummation of such Tag-Along Sale, furnish such other
evidence of the completion and time of completion of such
transfer and the terms thereof as may be reasonably requested by
the Tagging Persons.

(c) If at the termination of the Tag-Along Notice Period any
Tagging Person shall not have elected to participate in the Tag-
Along Sale, such Tagging Person will be deemed to have waived its
rights under Section 4.01(a) with respect to the transfer of its
securities pursuant to such Tag-Along Sale, but not with respect
to any future sales.

(d) If any Stockholder declines to exercise its Tag-Along Rights
or elects to exercise its Tag-Along Rights with respect to less
than such Tagging Person's Tag-Along Portion, the Tagging Persons
who do respond and the LLC shall be entitled to transfer,
pursuant to the Tag-Along Offer, an additional number of Company
Securities equal to the number of Company Securities constituting
their pro rata portion of such Tagging Person's Tag-Along Portion
with respect to which Tag-Along Rights were not exercised.

(e) The LLC and any Tagging Person who exercises the Tag-Along
Rights pursuant to this Section 4.01 may sell the Company
Securities subject to the Tag-Along Offer on the terms and
conditions set forth in the Tag-Along Notice (provided, however,
that the cash price payable in any such sale may exceed the cash
price specified in the Tag-Along Notice by up to 10%) within 120
days of the date on which Tag-Along Rights shall have been
waived, exercised or expire.

(f) In the event that the DLJ Entities propose to transfer a
number of Units equal to or exceeding 40% of the outstanding
Units in a single transaction or in a series of related
transactions on the date of the proposed sale, other than
transfers of Units (i) in a Public Offering or pursuant to Rule
144 (defined for these purposes to exclude Rule 144A under the
Securities Act) or (ii) to any Permitted Transferee of the LLC
(defined for these purposes to exclude, except in the case of a
general distribution to DLJ Partners, any Permitted Transferee
who is a Permitted Transferee solely by reason of being an
Affiliate of a DLJ Partner), the Board of Directors shall in good
faith determine an appropriate procedure which shall mutatis
mutandis reflect the procedures of this Section 4.01 to allow

<Page 17>
Company Securities to be sold proportionally by Other
Stockholders as part of such sale, and shall in good faith
determine an appropriate valuation for such Company Securities
reflecting the price per Unit at which the DLJ Entities propose
to sell the Units.

(g) This Section 4.01 shall terminate upon the Initial Public
Offering.

SECTION 4.02. Right to Compel Participation in Certain Transfers.
(a) If (i) the LLC proposes to transfer not less than 50% of its
Initial Ownership of Common Stock to a Third Party in a bona fide
sale or (ii) the LLC proposes an arms-length transfer in which
the shares of Common Stock to be transferred by the LLC and its
Permitted Transferees constitute more than 50% of the outstanding
shares of Common Stock (a "Section 4.02 Sale"), the LLC may at
its option require all Other Stockholders to sell the Drag-Along
Portion of the Subject Securities ("Drag-Along Rights") then held
by every Other Stockholder, and (subject to and at the closing of
the Section 4.02 Sale) to exercise all, but not less than all, of
the options held by every Other Stockholder and to sell all of
the shares of Common Stock received upon such exercise to such
Third Party, for the same consideration per share of Common Stock
and otherwise on the same terms and conditions as the LLC;
provided that any Other Stockholder who holds options the
exercise price per share of which is greater than the per share
price at which the Shares are to be sold to the Third Party may,
if required by the LLC to exercise such options, in place of such
exercise, submit to irrevocable cancellation thereof without any
liability for payment of any exercise price with respect thereto.
In the event the Section 4.02 Sale is not consummated with
respect to any shares acquired upon exercise of such options, or
the Section 4.02 Sale is not consummated, such options shall be
deemed not to have been exercised or canceled, as applicable. The
LLC shall provide written notice of such Section 4.02 Sale to the
Other Stockholders (a "Section 4.02 Notice") not later than the
15th Business Day prior to the proposed Section 4.02 Sale. The
Section 4.02 Notice shall identify the transferee, the number of
Subject Securities, the consideration for which a transfer is
proposed to be made (the "Section 4.02 Sale Price") and all other
material terms and conditions of the Section 4.02 Sale. The
number of shares of Common Stock to be sold by each Other
Stockholder will be the Drag-Along Portion of the shares of
Common Stock that such Other Stockholder owns. Each Other
Stockholder shall be required to participate in the Section 4.02
Sale on the terms and conditions set forth in the Section 4.02
Notice and to tender all its Subject Securities as set forth
below. The price payable in such transfer shall be the Section
4.02 Sale Price. Not later than the 10th Business Day following
the date of the Section 4.02 Notice (the "Section 4.02 Notice
Period"), each of the Other Stockholders shall deliver to a
representative of the LLC designated in the Section 4.02 Notice
certificates representing all Subject Securities representing the
Drag Along Portion held by such Other Stockholder,

<Page 18>
duly endorsed, together with all other documents required to be
executed in connection with such Section 4.02 Sale. If an Other
Stockholder should fail to deliver such certificates to the
representative of the LLC, the Company shall cause the books and
records of the Company to show that such Subject Securities are
bound by the provisions of this Section 4.02 and that such
Subject Securities shall be transferred to the purchaser of the
Subject Securities immediately upon surrender for transfer by the
holder thereof.

(b) The LLC shall have a period of 45 days from the date of
receipt of the Section 4.02 Notice to consummate the Section 4.02
Sale on the terms and conditions set forth in such Section 4.02
Sale Notice. If the Section 4.02 Sale shall not have been
consummated during such period, the LLC shall return to each of
the Other Stockholders all certificates representing Subject
Securities that such Other Stockholder delivered for transfer
pursuant hereto, together with any documents in the possession of
the LLC executed by the Other Stockholder in connection with such
proposed transfer, and all the restrictions on transfer contained
in this Agreement or otherwise applicable at such time with
respect to Common Stock owned by the Other Stockholders shall
again be in effect.

(c) Concurrently with the consummation of the transfer of Company
Securities pursuant to this Section 4.02, the LLC shall give
notice thereof to all Stockholders, shall remit to each of the
Stockholders who have surrendered their certificates the total
consideration (by bank or certified check) for the Subject
Securities transferred pursuant hereto and shall furnish such
other evidence of the completion and time of completion of such
transfer and the terms thereof as may be reasonably requested by
such Stockholders.


ARTICLE 5
REGISTRATION RIGHTS

SECTION 5.01. Demand Registration. (a) If the Company shall
receive a written request by the LLC or its Permitted Transferees
or DLJIP (any such requesting Person, a "Selling Stockholder")
that the Company effect the registration under the Securities Act
of all or a portion of such Selling Stockholder's Registrable
Securities, and specifying the intended method of disposition
thereof, then the Company shall promptly give written notice of
such requested registration (a "Demand Registration") at least 30
days prior to the anticipated filing date of the registration
statement relating to such Demand Registration to the Other
Stockholders and thereupon will use its best efforts to effect,
as expeditiously as possible, the registration under the
Securities Act of:

<Page 19>
(i) the Registrable Securities which the Company has been so
requested to register by the Selling Stockholders, then held by
the Selling Stockholders; and

(ii) subject to the restrictions set forth in Section 5.01(e),
all other Registrable Securities of the same type as that to
which the request by the Selling Stockholders relates which any
Other Stockholder entitled to request the Company to effect an
Incidental Registration (as such term is defined in Section 5.02)
pursuant to Section 5.02 (all such Stockholders, together with
the Selling Stockholders, the "Holders") has requested the
Company to register by written request received by the Company
within 15 days after the receipt by such Holders of such written
notice given by the Company,

all to the extent necessary to permit the disposition (in
accordance with the intended methods thereof as aforesaid) of the
Registrable Securities so to be registered; provided that,
subject to Section 5.01(d) hereof, the Company shall not be
obligated to effect (A) more than six Demand Registrations for
the LLC and its Permitted Transferees or (B) one Demand
Registration for DLJIP (which Demand Registration right may not
be exercised prior to the date that is 180 days after an Initial
Public Offering); and provided further that the Company shall not
be obligated to effect a Demand Registration unless the aggregate
proceeds expected to be received from the sale of the Common
Stock to be included in such Demand Registration, in the
reasonable opinion of DLJ Merchant Banking II, Inc. exercised in
good faith, equals or exceeds (Y) $10,000,000 if such Demand
Registration would constitute the Initial Public Offering, or (Z)
$5,000,000 in all other cases. In no event will the Company be
required to effect more than one Demand Registration within any
four-month period.

(b) Promptly after the expiration of the 15-day period referred
to in Section 5.01(a)(ii) hereof, the Company will notify all the
Holders to be included in the Demand Registration of the other
Holders and the number of Registrable Securities requested to be
included therein. The Selling Stockholders requesting a
registration under this Section may, at any time prior to the
effective date of the registration statement relating to such
registration, revoke such request, without liability to any of
the other Holders, by providing a written notice to the Company
revoking such request, in which case such request, so revoked,
shall be considered a Demand Registration unless the
participating Stockholders reimburse the Company for all costs
incurred by the Company in connection with such registration, or
unless such revocation arose out of the fault of the Company, in
which case such request shall not be considered a Demand
Registration.

<Page 20>
(c) The Company will pay all Registration Expenses in connection
with any Demand Registration.

(d) A registration requested pursuant to this Section shall not
be deemed to have been effected (i) unless the registration
statement relating thereto (A) has become effective under the
Securities Act and (B) has remained effective for a period of at
least 180 days (or such shorter period in which all Registrable
Securities of the Holders included in such registration have
actually been sold thereunder); provided that if after any
registration statement requested pursuant to this Section becomes
effective (x) such registration statement is interfered with by
any stop order, injunction or other order or requirement of the
SEC or other governmental agency or court and (y) less than 75%
of the Registrable Securities included in such registration
statement has been sold thereunder, such registration statement
shall not be considered a Demand Registration or (ii) if the
Maximum Offering Size (as defined below) is reduced in accordance
with Section 5.01(e) or 5.01(f) such that less than 66 2/3% of
the Registrable Securities of the Selling Stockholders sought to
be included in such registration are included.

(e) If a Demand Registration involves an Underwritten Public
Offering and the managing underwriter shall advise the Company
and the Selling Stockholders that, in its view, (i) the number of
Registrable Securities requested to be included in such
registration (including any securities which the Company proposes
to be included which are not Registrable Securities) or (ii) the
inclusion of some or all of the Registrable Securities owned by
the Holders, in any such case, exceeds the largest number of
securities which can be sold without having an adverse effect on
such offering, including the price at which such securities can
be sold (the "Maximum Offering Size"), the Company will include
in such registration, in the priority listed below, up to the
Maximum Offering Size:

(A) first: (1) in the case of a Demand by the LLC and its
Permitted Transferees, all Securities requested to be registered
by the Selling Stockholder and by all of its Permitted
Transferees and CRL, DLJIP, BB, TW and Carlyle (allocated, if
necessary for the offering not to exceed the Maximum Offering
Size, pro rata among such Persons on the basis of the relative
number of shares of Registrable Securities requested to be
registered), or (2) in the case of a Demand by DLJIP, all
Securities requested to be registered by the Selling Stockholder
and by all of its Permitted Transferees and BB, TW and Carlyle
(allocated, if necessary for the offering not to exceed the
Maximum Offering Size, pro rata among such Persons on the basis
of the relative number of shares of Registrable Securities
requested to be registered);

<Page 21>
(B) second: (1) in the case of a Demand by the LLC and its
Permitted Transferees, all Registrable Securities requested to be
included in such registration by any other Holder (allocated, if
necessary for the offering not to exceed the Maximum Offering
Size, pro rata among such other Holders on the basis of the
relative number of shares of Registrable Securities requested to
be included in such registration), or (2) in the case of a Demand
by DLJIP, all Registrable Securities requested to be included in
such registration by the LLC and its Permitted Transferees and by
CRL (allocated, if necessary for the offering not to exceed the
Maximum Offering Size, pro rata among such other Holders on the
basis of the relative number of shares of Registrable Securities
requested to be included in such registration);

(C) third: (1) in the case of a Demand by the LLC and its
Permitted Transferees, any securities proposed to be registered
by the Company, or (2) in the case of a Demand by DLJIP, all
Registrable Securities requested to be included in such
registration by any other Holder (allocated, if necessary for the
offering not to exceed the Maximum Offering Size, pro rata among
such other Holders on the basis of the relative number of shares
of Registrable Securities requested to be included in such
registration); and

(D) fourth: in the case of a Demand by DLJIP, any securities
proposed to be registered by the Company.

(f) If the Company files a shelf registration statement with
respect to the High Yield Warrants, the Company shall notify the
holders of the Warrants at least 20 days prior to such filing.
The holders of the Warrants shall have the right (which shall not
be deemed to be a use of a Demand Registration right), by notice
to the Company, to include the Warrants in such shelf
registration statement.
Notwithstanding anything in this Agreement to the contrary, this
Agreement shall
not be construed to confer on any Stockholder (other than holders
of Warrants in their capacity as such, together with any Persons
entitled to indemnification hereunder in connection therewith)
any rights in connection with such shelf registration statement.

SECTION 5.02. Incidental Registration. (a) If the Company
proposes to register any Company Securities under the Securities
Act (other than a registration (A) on Form S-8 or S-4 or any
successor or similar forms, (B) relating to Common Stock issuable
upon exercise of employee stock options or in connection with any
employee benefit or similar plan of the Company or (C) in
connection with a direct or indirect acquisition by the Company
of another company),

<Page 22>
whether or not for sale for its own account, it will each such
time, subject to the provisions of Section 5.02(b), give prompt
written notice at least 30 days prior to the anticipated filing
date of the registration statement relating to such registration
to the LLC and each Other Stockholder, which notice shall set
forth such Stockholder's rights under this Section 5.02 and shall
offer such Stockholders the opportunity to include in such
registration statement such number of Registrable Securities of
the same type as are proposed to be registered as each such
Stockholder may request (an "Incidental Registration"). Upon the
written request of any such Stockholder made within 15 days after
the receipt of notice from the Company (which request shall
specify the number of Registrable Securities intended to be
disposed of by such Stockholder), the Company will use its best
efforts to effect the registration under the Securities Act of
all Registrable Securities which the Company has been so
requested to register by such Stockholders, to the extent
requisite to permit the disposition of the Registrable Securities
so to be registered; provided that (I) if such registration
involves a Public Offering, all such Stockholders requesting to
be included in the Company's registration must sell their
Registrable Securities to the underwriters selected as provided
in Section 5.04(f) on the same terms and conditions as apply to
the Company and (II) if, at any time after giving written notice
of its intention to register any stock pursuant to this Section
5.02(a) and prior to the effective date of the registration
statement filed in connection with such registration, the Company
shall determine for any reason not to register such securities,
the Company shall give written notice to all such Stockholders
and, thereupon, shall be relieved of its obligation to register
any Registrable Securities in connection with such registration
(without prejudice, however, to rights of the LLC under Section
5.01). No registration effected under this Section 5.02 shall
relieve the Company of its obligations to effect a Demand
Registration to the extent required by Section 5.01.
The Company will pay all Registration Expenses in connection with
each registration of Registrable Securities requested pursuant to
this Section 5.02.

(b) If a registration pursuant to this Section 5.02 involves a
Public Offering (other than in the case of a Public Offering
requested by the LLC or any of its Permitted Transferees or the
Other Stockholders in a Demand Registration, in which case the
provisions with respect to priority of inclusion in such offering
set forth in Section 5.01(e) shall apply) and the managing
underwriter advises the Company that, in its view, the number of
Shares that the Company and such Stockholders intend to include
in such registration exceeds the Maximum Offering Size, the
Company will include in such registration, in the following
priority, up to the Maximum Offering Size:

(i) first, so much of the securities proposed to be registered by
the Company as would not cause the offering to exceed the Maximum
Offering Size;

<Page 23>
(ii) second, all Registrable Securities requested to be included
in such registration by the LLC and its Permitted Transferees or
any Other Stockholder pursuant to this Section 5.02 (allocated,
if necessary for the offering not to exceed the Maximum Offering
Size, pro rata among such Stockholders on the basis of the
relative number of shares of Registrable Securities so requested
to be included in such registration).

SECTION 5.03. Holdback Agreements. If any registration of
Registrable Securities shall be in connection with a Public
Offering, the LLC and its Permitted Transferees and each Other
Stockholder agrees not to effect any public sale or distribution,
including any sale pursuant to Rule 144, or any successor
provision, under the Securities Act, of any Registrable
Securities, and not to effect any such public sale or
distribution of any other Common Stock of the Company or of any
stock convertible into or exchangeable or exercisable for any
Common Stock of the Company (in each case, other than as part of
such Public Offering) during the 14 days prior to the effective
date of such registration statement (except as part of such
registration) or during the period after such effective date
equal to the lesser of (i) such period of time as agreed between
such managing underwriter and the Company and (ii) 180 days (such
lesser period, the "Applicable Holdback Period").

SECTION 5.04. Registration Procedures. Whenever Stockholders
request that any Registrable Securities be registered pursuant to
Section 5.01 or 5.02, the Company will, subject to the provisions
of such Sections, use its best efforts to effect the registration
and the sale of such Registrable Securities in accordance with
the intended method of disposition thereof as quickly as
practicable, and in connection with any such request:

(a) The Company will as expeditiously as possible prepare and
file with the SEC a registration statement on any form for which
the Company then qualifies or which counsel for the Company shall
deem appropriate and which form shall be available for the sale
of the Registrable Securities to be registered thereunder in
accordance with the intended method of distribution thereof, and
use its best efforts to cause such filed registration statement
to become and remain effective for a period of not less than 180
days.

(b) The Company will, if requested, prior to filing a
registration statement or prospectus or any amendment or
supplement thereto, furnish to participating Stockholder and each
underwriter, if any, of the Registrable Securities covered by
such registration statement copies of such registration statement
as proposed to be filed, and thereafter the Company will furnish
to such Stockholder and underwriter, if any, such number of
copies of such registration

<Page 24>
statement, each amendment and supplement thereto (in each case
including all exhibits thereto and documents incorporated by
reference therein), the prospectus included in such registration
statement (including each preliminary prospectus) and such other
documents as such Stockholder or underwriter may reasonably
request in order to facilitate the disposition of the Registrable
Securities owned by such Stockholder.

(c) After the filing of the registration statement, the Company
will promptly notify each Stockholder holding Registrable
Securities covered by such registration statement of any stop
order issued or threatened by the SEC and take all reasonable
actions required to prevent the entry of such stop order or to
remove it if entered.

(d) The Company will use its best efforts to (i) register or
qualify the Registrable Securities covered by such registration
statement under such other securities or blue sky laws of such
jurisdictions in the United States as any Stockholder holding
such Registrable Securities reasonably (in light of such
Stockholder's intended plan of distribution) requests and (ii)
cause such Registrable Securities to be registered with or
approved by such other governmental agencies or authorities as
may be necessary by virtue of the business and operations of the
Company and do any and all other acts and things that may be
reasonably necessary or advisable to enable such Stockholder to
consummate the disposition of the Registrable Securities owned by
such Stockholder; provided that the Company will not be required
to (A) qualify generally to do business in any jurisdiction where
it would not otherwise be required to qualify but for this
paragraph (d), (B) subject itself to taxation in any such
jurisdiction or (C) consent to general service of process in any
such jurisdiction.

(e) The Company will immediately notify each Stockholder holding
such Registrable Securities, at any time when a prospectus
relating thereto is required to be delivered under the Securities
Act, of the occurrence of an event requiring the preparation of a
supplement or amendment to such prospectus so that, as thereafter
delivered to the purchasers of such Registrable Securities, such
prospectus will not contain an untrue statement of a material
fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein not
misleading and promptly prepare and make available to each such
Stockholder any such supplement or amendment.

(f) The LLC will have the right, in its sole discretion, to
select an underwriter or underwriters in connection with any
Public Offering, which underwriter or underwriters may include
any Affiliate of any DLJ Entity. In connection with any Public
Offering, the Company will enter into customary agreements
(including an underwriting agreement in customary form) and take

<Page 25>
such other actions as are reasonably required in order to
expedite or facilitate the disposition of Registrable Securities
in any such Public Offering, including the engagement of a
"qualified independent underwriter" in connection with the
qualification of the underwriting arrangements with the NASD.

(g) Upon the execution of confidentiality agreements in form and
substance satisfactory to the Company, the Company will make
available for inspection by any Stockholder and any underwriter
participating in any disposition pursuant to a registration
statement being filed by the Company pursuant to this Section
5.04 and any attorney, accountant or other professional retained
by any such Stockholder or underwriter (collectively, the
"Inspectors"), all financial and other records, pertinent
corporate documents and properties of the Company (collectively,
the "Records") as shall be reasonably necessary to enable them to
exercise their due diligence responsibility, and cause the
Company's officers, directors and employees to supply all
information reasonably requested by any Inspectors in connection
with such registration statement. Records that the Company
determines, in good faith, to be confidential and that it
notifies the Inspectors are confidential shall not be disclosed
by the Inspectors unless (i) the disclosure of such Records is
necessary to avoid or correct a misstatement or omission in such
registration statement or (ii) the release of such Records is
ordered pursuant to a subpoena or other order from a court of
competent jurisdiction. Each Stockholder agrees that information
obtained by it as a result of such inspections shall be deemed
confidential and shall not be used by it as the basis for any
market transactions in the Company Securities or its Affiliates
unless and until such is made generally available to the public.
Each Stockholder further agrees that it will, upon learning that
disclosure of such Records is sought in a court of competent
jurisdiction, give notice to the Company and allow the Company,
at its expense, to undertake appropriate action to prevent
disclosure of the Records deemed confidential.

(h) The Company will furnish to each such Stockholder and to each
such underwriter, if any, a signed counterpart, addressed to such
underwriter, of (i) an opinion or opinions of counsel to the
Company and (ii) a comfort letter or comfort letters from the
Company's independent public accountants, each in customary form
and covering such matters of the type customarily covered by
opinions or comfort letters, as the case may be, as a majority of
such Stockholders or the managing underwriter therefor reasonably
requests.

(i) The Company will otherwise use its best efforts to comply
with all applicable rules and regulations of the SEC, and make
available to its stockholders, as soon as reasonably practicable,
an earnings statement covering a period of 12 months, beginning
within three months after the effective date of the

<Page 26>
registration statement, which earnings statement shall satisfy
the provisions of Section 11(a) of the Securities Act.

The Company may require each such Stockholder to promptly furnish
in writing to the Company such information regarding the
distribution of the Registrable Securities as the Company may
from time to time reasonably request and such other information
as may be legally required in connection with such registration.

Each such Stockholder agrees that, upon receipt of any notice
from the Company of the happening of any event of the kind
described in Section 5.04(e), such Stockholder will forthwith
discontinue disposition of Registrable Securities pursuant to the
registration statement covering such Registrable Securities until
such Stockholder's receipt of the copies of the supplemented or
amended prospectus contemplated by Section 5.04(e), and, if so
directed by the Company, such Stockholder will deliver to the
Company all copies, other than any permanent file copies then in
such Stockholder's possession, of the most recent prospectus
covering such Registrable Securities at the time of receipt of
such notice. In the event that the Company shall give such
notice, the Company shall extend the period during which such
registration statement shall be maintained effective (including
the period referred to in Section 5.04(a)) by the number of days
during the period from and including the date of the giving of
notice pursuant to Section 5.04(e) to the date when the Company
shall make available to such Stockholder a prospectus
supplemented or amended to conform with the requirements of
Section 5.04(e).

SECTION 5.05. Indemnification by the Company. The Company agrees
to indemnify and hold harmless each Stockholder holding
Registrable Securities covered by a registration statement, its
officers, directors and agents, and each person, if any, who
controls such Stockholder within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act from and against
any and all losses, claims, damages and liabilities caused by any
untrue statement or alleged untrue statement of a material fact
contained in any registration statement or prospectus relating to
the Registrable Securities (as amended or supplemented if the
Company shall have furnished any amendments or supplements
thereto) or any preliminary prospectus, or caused by any omission
or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not
misleading, except insofar as such losses, claims, damages or
liabilities are caused by any such untrue statement or omission
or alleged untrue statement or omission based upon information
furnished in writing to the Company by such Stockholder or on
such Stockholder's behalf expressly for use therein; provided
that with respect to any untrue statement or omission or alleged
untrue statement or omission made in any preliminary prospectus,
or in any

<Page 27>
prospectus, as the case may be, the indemnity agreement contained
in this paragraph shall not apply to the extent that any such
loss, claim, damage, liability or expense results from the fact
that a current copy of the prospectus (or, in the case of a
prospectus, the prospectus as amended or supplemented) was not
sent or given to the person asserting any such loss, claim,
damage, liability or expense at or prior to the written
confirmation of the sale of the Registrable Securities concerned
to such person if it is determined that the Company has provided
such prospectus and it was the responsibility of such Stockholder
to provide such person with a current copy of the prospectus (or
such amended or supplemented prospectus, as the case may be) and
such current copy of the prospectus (or such amended or
supplemented prospectus, as the case may be) would have cured the
defect giving rise to such loss, claim, damage, liability or
expense. The Company also agrees to indemnify any underwriters of
the Registrable Securities, their officers and directors and each
person who controls such underwriters on substantially the same
basis as that of the indemnification of the Stockholders provided
in this Section 5.05.

SECTION 5.06. Indemnification by Participating Stockholders. Each
Stockholder holding Registrable Securities included in any
registration statement agrees, severally but not jointly, to
indemnify and hold harmless the Company, its officers, directors
and agents and each person, if any, who controls the Company
within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from the Company to such Stockholder, but
only (i) with respect to information furnished in writing by such
Stockholder or on such Stockholder's behalf expressly for use in
any registration statement or prospectus relating to the
Registrable Securities, or any amendment or supplement thereto,
or any preliminary prospectus or (ii) to the extent that any
loss, claim, damage, liability or expense described in Section
5.05 results from the fact that a current copy of the prospectus
(or, in the case of a prospectus, the prospectus as amended or
supplemented) was not sent or given to the person asserting any
such loss, claim, damage, liability or expense at or prior to the
written confirmation of the sale of the Registrable Securities
concerned to such person if it is determined that it was the
responsibility of such Stockholder to provide such person with a
current copy of the prospectus (or such amended or supplemented
prospectus, as the case may be) and such current copy of the
prospectus (or such amended or supplemented prospectus, as the
case may be) would have cured the defect giving rise to such
loss, claim, damage, liability or expense. Each such Stockholder
also agrees to indemnify and hold harmless underwriters of the
Registrable Securities, their officers and directors and each
person who controls such underwriters on substantially the same
basis as that of the indemnification of the Company provided in
this Section 5.06. As a condition to including Registrable
Securities in any registration statement filed in accordance with
Article 5 hereof, the Company may require that it shall have

<Page 28>
received an undertaking reasonably satisfactory to it from any
underwriter to indemnify and hold it harmless to the extent
customarily provided by underwriters with respect to similar
securities.

SECTION 5.07. Conduct of Indemnification Proceedings. In case any
proceeding (including any governmental investigation) shall be
instituted involving any person in respect of which indemnity may
be sought pursuant to this Article 5, such person (an
"Indemnified Party") shall promptly notify the person against
whom such indemnity may be sought (the "Indemnifying Party") in
writing and the Indemnifying Party shall assume the defense
thereof, including the employment of counsel reasonably
satisfactory to such Indemnified Party, and shall assume the
payment of all fees and expenses; provided that the failure of
any Indemnified Party so to notify the Indemnifying Party shall
not relieve the Indemnifying Party of its obligations hereunder
except to the extent that the Indemnifying Party is materially
prejudiced by such failure to notify. In any such proceeding, any
Indemnified Party shall have the right to retain its own counsel,
but the fees and expenses of such counsel shall be at the expense
of such Indemnified Party unless (i) the Indemnifying Party and
the Indemnified Party shall have mutually agreed to the retention
of such counsel or (ii) in the reasonable judgment of such
Indemnified Party representation of both parties by the same
counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that the
Indemnifying Party shall not, in connection with any proceeding
or related proceedings in the same jurisdiction, be liable for
the reasonable fees and expenses of more than one separate firm
of attorneys (in addition to any local counsel) at any time for
all such Indemnified Parties, and that all such fees and expenses
shall be reimbursed as they are incurred. In the case of any such
separate firm for the Indemnified Parties, such firm shall be
designated in writing by the Indemnified Parties. The
Indemnifying Party shall not be liable for any settlement of any
proceeding effected without its written consent, but if settled
with such consent, or if there be a final judgment for the
plaintiff, the Indemnifying Party shall indemnify and hold
harmless such Indemnified Parties from and against any loss or
liability (to the extent stated above) by reason of such
settlement or judgment. No Indemnifying Party shall, without the
prior written consent of the Indemnified Party, effect any
settlement of any pending or threatened proceeding in respect of
which any Indemnified Party is or could have been a party and
indemnity could have been sought hereunder by such Indemnified
Party, unless such settlement includes an unconditional release
of such Indemnified Party from all liability arising out of such
proceeding.

SECTION 5.08. Contribution. If the indemnification provided for
in this Article 5 is unavailable to the Indemnified Parties in
respect of any losses, claims, damages or liabilities referred to
herein, then each such Indemnifying Party, in lieu of
indemnifying such Indemnified Party, shall contribute to the
amount paid

<Page 29>
or payable by such Indemnified Party as a result of such losses,
claims, damages or liabilities (i) as between the Company and the
Stockholders holding Registrable Securities covered by a
registration statement on the one hand and the underwriters on
the other, in such proportion as is appropriate to reflect the
relative benefits received by the Company and such Stockholders
on the one hand and the underwriters on the other, from the
offering of the Registrable Securities, or if such allocation is
not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits but also
the relative fault of the Company and such Stockholders on the
one hand and of such underwriters on the other in connection with
the statements or omissions which resulted in such losses,
claims, damages or liabilities, as well as any other relevant
equitable considerations and (ii) as between the Company on the
one hand and each such Stockholder on the other, in such
proportion as is appropriate to reflect the relative fault of the
Company and of each such Stockholder in connection with such
statements or omissions, as well as any other relevant equitable
considerations. The relative benefits received by the Company and
such Stockholders on the one hand and such underwriters on the
other shall be deemed to be in the same proportion as the total
proceeds from the offering (net of underwriting discounts and
commissions but before deducting expenses) received by the
Company and such Stockholders bear to the total underwriting
discounts and commissions received by such underwriters, in each
case as set forth in the table on the cover page of the
prospectus. The relative fault of the Company and such
Stockholders on the one hand and of such underwriters on the
other shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact
relates to information supplied by the Company and such
Stockholders or by such underwriters. The relative fault of the
Company on the one hand and of each such Stockholder on the other
shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to
information supplied by such party, and the parties' relative
intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

The Company and the Stockholders agree that it would not be just
and equitable if contribution pursuant to this Section 5.08 were
determined by pro rata allocation (even if the underwriters were
treated as one entity for such purpose) or by any other method of
allocation which does not take account of the equitable
considerations referred to in the immediately preceding
paragraph. The amount paid or payable by an Indemnified Party as
a result of the losses, claims, damages or liabilities referred
to in the immediately preceding paragraph shall be deemed to
include, subject to the limitations set forth above, any legal or
other expenses reasonably incurred by such Indemnified Party in
connection with investigating or defending any such action or
claim. Notwithstanding the provisions of this

<Page 30>
Section 5.08, no underwriter shall be required to contribute any
amount in excess of the amount by which the total price at which
the Registrable Securities underwritten by it and distributed to
the public were offered to the public exceeds the amount of any
damages which such underwriter has otherwise been required to pay
by reason of such untrue or alleged untrue statement or omission
or alleged omission, and no Stockholder shall be required to
contribute any amount in excess of the amount by which the total
price at which the Registrable Securities of such Stockholder
were offered to the public exceeds the amount of any damages
which such Stockholder has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or
alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. Each
such Stockholder's obligation to contribute pursuant to this
Section 5.08 is several in the proportion that the proceeds of
the offering received by such Stockholder bears to the total
proceeds of the offering received by all such Stockholders and
not joint.

SECTION 5.09. Participation in Public Offering. No Person may
participate in any Public Offering hereunder unless such Person
(a) agrees to sell such Person's securities on the basis provided
in any underwriting arrangements approved by the Persons entitled
hereunder to approve such arrangements, and (b) completes and
executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably and
customarily required under the terms of such underwriting
arrangements and the provisions of this Agreement in respect of
registration rights.

SECTION 5.10. Other Indemnification. Indemnification similar to
that specified herein (with appropriate modifications) shall be
given by the Company and each Stockholder participating therein
with respect to any required registration or other qualification
of securities under any federal or state law or regulation or
governmental authority other than the Securities Act.

SECTION 5.11. Cooperation by the Company. In the event any
Stockholder shall transfer any Registrable Securities pursuant to
Rule 144A under the Securities Act, the Company shall cooperate
with such Stockholder (which shall include, without limitation,
making registration rights with respect to the Registrable
Securities to be sold (or securities issuable or to be issued in
exchange therefor) available to the ultimate purchasers thereof)
and shall provide to such Stockholder such information as such
Stockholder shall reasonably request, provided that any
registration rights made available pursuant hereto shall not be
on terms substantially more favorable to the possessors thereof
than the registration rights granted herein to the LLC.

Stockholder at least twenty days prior to any issuance of Company

employment agreement or stock purchase, option, stock option or
other compensation plan of the Company or any Subsidiary to
become a party hereto shall (unless already bound hereby) execute
and deliver to the Company an agreement to be bound by this
Agreement and shall thenceforth be a "Stockholder". Any

hereafter in effect, or appointing a receiver, liquidator,
custodian, trustee, sequestrator (or similar official) of the
Issuer or for any substantial part of the property of the Issuer
or ordering the winding up or liquidation of the affairs of the
Issuer and such decree or order shall remain unstayed and in
effect for a period of 60 days;
or
(d) the Issuer shall commence a voluntary case under any
applicable bankruptcy, insolvency or other similar law relating
to or affecting creditors' rights generally now or hereafter in
effect, or consent to the entry of an order for relief in an
involuntary case under any such law, or consent to the
appointment or taking possession by a receiver, liquidator,
custodian, trustee, sequestrator (or similar official) of the
Issuer or for any substantial part of the property of the Issuer
or the Issuer shall make any general assignment for the benefit
of creditors;
then, subject to Article 5 hereof, the Holder may, in each and
every such case, by notice to the Issuer declare the principal
amount of this Note, determined as set forth below, to be, and
such principal amount shall thereupon become, immediately due and
payable. The principal amount so due and payable shall be deemed
for this purpose to be equal to the Accreted Value on the date
such declaration is made.

SECTION 2.02. Powers and Remedies Cumulative; Delay or Omission
Not Waiver of Default. No right or remedy herein conferred upon
or reserved to the Holder is intended to be exclusive of any
other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every
other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall
not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

No delay or omission of the Holder to exercise any right or power
accruing upon any Default or Event of Default occurring and
continuing as aforesaid shall impair any such right or power or
shall be construed to be a waiver of any such Default or Event of
Default or an acquiescence therein; and every power and remedy
given by this Note or by law may be exercised from time to time,
and as often as shall be deemed expedient, by the Holder.

Any term or provision of this Note (including this Section 2.02)
to the contrary notwithstanding, the Holder shall have no right
(directly or indirectly) to exercise, nor shall the Holder in
fact exercise (directly or indirectly), any rights or remedies
against the Issuer, any of its Subsidiaries or any of their
respective assets in respect of any breach hereunder or
otherwise, nor shall the Holder commence (directly or indirectly)
any litigation, action or other proceeding against any of the
foregoing in respect of any breach hereunder or otherwise, unless
(but only unless) an Event of Default has occurred and is
continuing, and, in such event, the exercise of any such right or
remedy shall be subject to Article 5 hereof.

SECTION 2.03. Waiver of Past Defaults. The Holder may, but has no
obligation to, waive in writing, any past Default hereunder and
its consequences. In the case of any such waiver, the Issuer and
the Holder shall be restored to their former positions and rights
hereunder, respectively; but no such waiver shall extend to any
subsequent or other Default or impair any right consequent
thereon.

Upon any such waiver, such Default shall cease to exist and be
deemed to have been cured and not to have occurred, and any
Default arising therefrom shall be deemed to have been cured, and
not to have occurred for every purpose of the Note; but no such
waiver shall extend to any subsequent or other Default or impair
any right consequent thereon.

ARTICLE 3

Charles River Laboratories, Inc., as in effect on the date
hereof. Exclusively for purposes of the foregoing clauses (i),
(ii) and (iii) of this Section 3.02(c) (and not for purposes of
any other part of Section 3.02 or this Note), references to the
"Issuer" shall mean the Issuer together with Charles River
Laboratories, Inc., and the Subsidiaries of Charles River
Laboratories, Inc.

ARTICLE 4
REDEMPTION

SECTION 4.01. Redemption at Issuer's Option. (a) The Issuer at
its option may, upon twenty Business Days' written notice to the
Holder, at any time redeem all of this Note at a price equal to
the Accreted Value on the date of redemption.
(b) The notice shall state: (i) the redemption date, which shall
be a date not more than thirty Business Days after the date of
the notice of redemption; (ii) the redemption price; and (iii)
the place or places where the Note is to be surrendered for
payment of the redemption price, which may be at either the
principal place of business of the Issuer or a location in the
City of New York, State of New York.
(c) Notice having been mailed as aforesaid, from and after the
redemption date (provided that the Issuer shall have tendered the
redemption price against delivery of the Note), interest on the
Note shall cease to accrue, and all rights of the Holder (except
the right to receive from the Issuer the redemption price) shall
cease. Upon surrender of the Note in accordance with said notice
(properly endorsed or assigned for transfer, if the Board of
Directors of the Issuer shall so require and the notice shall so
state), the Note shall be redeemed by the Issuer at the aforesaid
redemption price.

SECTION 4.02. Redemption upon Change of Control. (a) If there
shall occur a Change in Control (as defined below), the Holder
shall have the right, at its option, to require the Issuer to
redeem, and upon the exercise of such right the Issuer shall
redeem, the Note at a price equal to the Accreted Value thereof
on the date of redemption. Such right of the Holder shall (i) be
subordinated and junior in right of payment to the prior payment
in full in cash of all Senior Indebtedness, the holders of which
have (and exercise) the right to receive such payment either
prior to or in connection with such Change of Control, and (ii)
except as set forth in the preceding clause (i), not be subject
to Article 5 hereof. For purposes of this Section 4.02, "Change
of Control" means (i) a "person" or "group" (within the meaning
of Sections 13(d) and 14(d)(2) of the Securities Exchange Act of
1934, as amended), other than the DLJ Entities (as defined in the
Investors' Agreement), (A) becoming the beneficial owner, by way
of merger, consolidation or otherwise, of 51% or more of the
voting power of all classes of voting securities of the Issuer or
(B) acquiring the right to elect a majority of the Board of
Directors of the Issuer, or (ii) the sale or transfer of all or
substantially all of the assets of the Issuer and its
subsidiaries taken as a whole (other than to one or more directly
or indirectly wholly-owned subsidiaries of the Issuer).
(b) On or before the tenth day after the occurrence of any Change
of Control, the Issuer shall send the Holder a notice (a
"Redemption Notice") advising the Holder of its rights hereunder
and specifying the date, not less than 20 nor more than 60 days
after the date such notice is delivered to the Holder, on which
the Issuer proposes to redeem the Note if the Holder requests
redemption pursuant to Section 4.02; provided that no failure of
the Issuer to give such notice shall limit the rights of the
Holder hereunder. If the Holder wishes to exercise its rights
hereunder it shall deliver to the Issuer, on or before the
fifteenth day after receipt of the Redemption Notice, written
notice (which shall be irrevocable) of the exercise of such
right.
(c) From and after the redemption date set forth in the
Redemption Notice (provided that the Issuer shall have tendered
the redemption price against delivery of the Note), interest on
the Note shall cease to accrue, and all rights of the Holder with
respect to the Note (except the right to receive from the Issuer
the redemption price) shall cease. Upon surrender in accordance
with said notice of the Note (properly endorsed or assigned for
transfer, if the Board of Directors of the Issuer shall so
require and the Redemption Notice shall so state), the Note shall
be redeemed by the Issuer at the aforesaid redemption price.

ARTICLE 5
SUBORDINATION

SECTION 5.01. Note Subordinated to Senior Indebtedness. The
Issuer covenants and agrees and the Holder, by its acceptance
hereof, likewise covenants and agrees, in each case
notwithstanding any other provisions of this Note or any other
agreement, document or instrument (it being the express agreement
of the Holder that the provisions of this Article 5 shall govern
in the event of any conflicting terms or provisions herein or
otherwise), that the Note shall be subject to the provisions of
this Article 5; and each person holding the Note, whether upon
original issue or upon transfer, assignment or exchange thereof
accepts and agrees that the payment of the principal of, or any
other amounts or obligations (monetary or otherwise) on, under or
in respect of the Note by or on behalf of the Issuer
(collectively, the "Subordinated Obligations") shall, to the
extent and in the manner herein set forth, be subordinated and
junior in right of payment, to the prior payment in full in cash
of all Senior Indebtedness.

SECTION 5.02. No Payment on Note So Long As Senior Indebtedness
Remains Outstanding. (a) No payment shall be made by or on behalf
of the Issuer with respect to all or any portion of the
Subordinated Obligations, nor may the Issuer directly or
indirectly acquire the Note or Subordinated Obligations for cash,
property, securities or otherwise, so long as any obligations on,
under or in respect of any Senior Indebtedness (or any commitment
to extend Senior Indebtedness) remain outstanding.
(b) In the event that any payment shall be received by the Holder
when such payment is prohibited by Section 5.02(a), such payment
shall be held in trust for the benefit of, and shall be paid over
or delivered to, the holders of Senior Indebtedness or their
respective representatives, or to the trustee or trustees under
any indenture pursuant to which any of such Senior Indebtedness
may have been issued, as their respective interests may appear,
in the form in which received (except for any necessary
endorsements).


SECTION 5.03. Payment over of Proceeds upon Dissolution, etc. (a)
Upon any payment or distribution of cash, securities or other
assets, of the Issuer of any kind or character, whether in cash,
property, securities or otherwise, to creditors upon any
dissolution or winding-up or total or partial liquidation or
reorganization of the Issuer, whether voluntary or involuntary or
in bankruptcy, insolvency, receivership or other proceedings, all
amounts due or to become due upon all Senior Indebtedness shall
first be paid in full in cash, before any payment is made on
account of any Subordinated Obligations or to acquire the Note
for cash or property. Upon any such dissolution, winding-up,
liquidation or reorganization, any payment or distribution of
assets of the Issuer of any kind or character, whether in cash,
property or securities, to which the Holder would be entitled,
except for the provisions hereof, shall be paid by the Issuer or
by any receiver, trustee in bankruptcy, liquidating trustee,
agent or other person making such payment or distribution, or by
the Holder if received by it, directly to the holders of Senior
Indebtedness (pro rata to such holders on the basis of the
respective amounts of Senior Indebtedness held by such holders)
or their respective representatives, or to the trustee or
trustees under any indenture pursuant to which any of such Senior
Indebtedness may have been issued, as their respective interests
may appear, for application to the payment of Senior Indebtedness
remaining unpaid until all such Senior Indebtedness has been paid
in full in cash after giving effect to any prior or concurrent
payment, distribution or provision therefor to or for the holders
of Senior Indebtedness.
(b) In the event that any payment or distribution of assets of
the Issuer of any kind or character, whether in cash, property or
securities, shall be received by the Holder when such payment or
distribution is prohibited by Section 5.03(a), such payment or
distribution shall be held in trust for the benefit of, and shall
be paid over or delivered to, the holders of Senior Indebtedness
(pro rata to such holders on the basis of the respective amount
of Senior Indebtedness held by such holders) or their respective
representatives, or to the trustee or trustees under any
indenture pursuant to which any of such Senior Indebtedness may
have been issued, as their respective interests may appear, in
the form in which received (except for any necessary
endorsements), for application to the payment of Senior
Indebtedness remaining unpaid until all such Senior Indebtedness
has been paid in full in cash, after giving effect to any
concurrent payment, distribution or provision therefor to or for
the holders of such Senior Indebtedness.

SECTION 5.04. Limitation on Remedies. So long as any obligations
on, under or in respect of any Senior Indebtedness (or any
commitment to extend Senior Indebtedness) remain outstanding, the
Holder may not declare, or join in the declaration of, any
Subordinated Obligations to be due and payable prior to the
maturity thereof or otherwise accelerate the maturity of the
principal of the Note or other amounts due on, under or in
respect thereof. At no time may the Holder commence any
administrative, legal or equitable action against the Issuer, any
of its Subsidiaries or any of their respective properties in
respect of the foregoing or in order to collect any amount
payable with respect to this Note upon maturity, including
filing, or joining in the filing of, any bankruptcy or insolvency
petition against the Issuer, provided that the Holder may file a
proof of claim in any such proceeding so long as such proof of
claim acknowledges the subordination of the Note on the terms set
forth herein.

SECTION 5.05. Subrogation. Upon, and subject to, the payment in
full in cash of all principal of, interest on and other amounts
and obligations on, under or in respect of Senior Indebtedness,
the Holder shall be subrogated to the rights of the holders of
Senior Indebtedness to receive payments or distributions of cash,
property or securities of the Issuer applicable to the Senior
Indebtedness until all such principal and other amounts and
obligations on the Note shall be paid in full in cash; and, for
the purposes of such subrogation, (a) no payments or
distributions to the holders of the Senior Indebtedness of any
cash, property or securities to which the Holder would be
entitled except for the provisions of this Article 5, and no
payment over pursuant to the provisions of this Article 5 to the
holders of Senior Indebtedness by the Holder shall, as between
the Issuer, its creditors other than holders of Senior
Indebtedness, and the Holder, be deemed to be a payment by the
Issuer to or on account of principal of, interest on and other
amounts and obligations owing on, under or in respect of Senior
Indebtedness, and (b) no payment or distributions of cash,
property or securities to or for the benefit of the Holder
pursuant to this Section 5.05, which would otherwise have been
paid to the holders of Senior Indebtedness shall be deemed to be
a payment by the Issuer to or for the account of the Note.

If any payment or distribution to which the Holder would
otherwise have been entitled but for the provisions of this
Article 5 shall have been applied, pursuant to the provisions of
this Article 5, to the payment of all amounts payable under or in
respect of Senior Indebtedness, then and in such case, the Holder
shall be entitled to receive from the holders of such Senior
Indebtedness any payments or distributions actually received by
such holders of Senior Indebtedness in excess of the amount
required to make payment in full in cash of such Senior
Indebtedness.

SECTION 5.06. Obligations of Issuer Unconditional. It is
understood that the provisions of this Article 5 are intended
solely for the purpose of defining the relative rights of the
Holder, on the one hand, and the holders of the Senior
Indebtedness, on the other hand. Nothing contained in Article 5
or elsewhere in this Note is intended to or shall impair, as
between the Issuer and the Holder, the obligation of the Issuer,
which is absolute and unconditional, to pay to the Holder the
principal amount of this Note as and when the same shall become
due and payable in accordance with its terms, or is intended to
or shall affect the relative rights of the Holder and creditors
of the Issuer other than the holders of the Senior Indebtedness,
nor shall anything herein prevent the Holder from exercising all
remedies otherwise permitted by applicable law upon default under
this Note, subject to the rights, if any, under Article 5 of the
holders of the Senior Indebtedness in respect of cash, property
or securities of the Issuer received upon the exercise of any
such remedy.

SECTION 5.07. Reliance on Judicial Order or Certificate of
Liquidating Agent. Upon any payment or distribution of assets of
the Issuer referred to in Article 5, the Holder shall be entitled
to rely upon any order or decree made by any court of competent
jurisdiction in which bankruptcy, dissolution, winding-up,
liquidation or reorganization proceedings (as to which the
holders of Senior Indebtedness are, or had the opportunity to
become, parties) are pending, or a certificate of the receiver,
trustee in bankruptcy, liquidating trustee, agent or other person
making such payment or distribution, delivered to the Holder, for
the purpose of ascertaining the persons entitled to participate
in such distribution, the holders of the Senior Indebtedness and
other indebtedness of the Issuer, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and
all other facts pertinent thereto or to Article 5 of this Note.

SECTION 5.08. Subordination Rights Not Impaired by Acts or
Omissions of the Issuer or holders of Senior Indebtedness. No
right of any present or future holders of any Senior Indebtedness
to enforce subordination as provided herein will at any time in
any way be prejudiced or impaired by any act or failure to act on
the part of the Issuer or by any act or failure to act, in good
faith, by any such holder, or by any noncompliance by the Issuer
with the terms of this Note, regardless of any knowledge thereof
which any such holder may have or otherwise be charged with. The
holders of Senior Indebtedness may extend, renew, amend, amend
and restate, supplement or otherwise modify the terms of the
Senior Indebtedness or any security therefor and release, sell or
exchange such security and otherwise deal freely with the Issuer,
all without affecting the liabilities and obligations of the
Holder.

ARTICLE 6
LIMITATIONS ON TRANSFERS

SECTION 6.01. No Transfer to Adverse Person. Neither this Note
nor any interest therein shall be transferrable to an Adverse
Person.

SECTION 6.02. Right of First Refusal. (a) The Holder may transfer
the Note or any interest therein to a third party who is not an
Adverse Person, in a bona fide sale (a "Third Party Sale"),
provided that the Holder shall have complied with the conditions
specified in paragraph (b) of this Section 6.02.
(b) Prior to effecting any Third Party Sale, the Holder will
deliver to DLJMB a written notice specifying the terms and
conditions of the proposed Third Party Sale, together with a copy
of the proposal, letter of intent or agreement negotiated with
the third party (the "Offer Notice"). If DLJMB delivers to the
Holder a written notice (an "Acceptance Notice") within 10 days
following the delivery of the Offer Notice (the "Acceptance
Period") stating that one or more of the DLJ Entities is willing
to purchase the Note or the interest therein on the terms set
forth in the Offer Notice, the Holder will sell the Note or the
interest therein to such DLJ Entity or Entities on the terms set
forth in the Offer Notice. If no Acceptance Notice is delivered
to the Holder prior to the expiration of the Acceptance Period,
the Holder may consummate the proposed Third Party Sale during
the 30-day period immediately following the expiration of the
Acceptance Period.
