            2.2 Right of Contribution. Each Guarantor hereby agrees that to the
extent that a Guarantor shall have paid more than its proportionate share of any
payment made hereunder, such Guarantor shall be entitled to seek and receive
contribution from and against any other Guarantor hereunder which has not paid
its proportionate share of such payment. Each Guarantor's right of contribution
shall be subject to the terms and conditions of Section 2.3. The

                                        6
<PAGE>   11
provisions of this Section 2.2 shall in no respect limit the obligations and
liabilities of any Guarantor to the Lender, and each Guarantor shall remain
liable to the Lender for the full amount guaranteed by such Guarantor hereunder.

            2.3 No Subrogation. Notwithstanding any payment made by any
Guarantor hereunder or any set-off or application of funds of any Guarantor by
the Lender, no Guarantor shall be entitled to be subrogated to any of the rights
of the Lender against the Borrower or any other Guarantor or any collateral
security or guarantee or right of offset held by the Lender for the payment of
the Borrower Obligations, nor shall any Guarantor seek or be entitled to seek
any contribution or reimbursement from the Borrower or any other Guarantor in
respect of payments made by such Guarantor hereunder, until all amounts owing to
the Lender by the Borrower on account of the Borrower Obligations are paid in
full. If any amount shall be paid to any Guarantor on account of such
subrogation rights at any time when all of the Borrower Obligations shall not
have been paid in full, such amount shall be held by such Guarantor in trust for
the Lender, segregated from other funds of such Guarantor, and shall, forthwith
upon receipt by such Guarantor, be turned over to the Lender in the exact form
received by such Guarantor (duly indorsed by such Guarantor to the Lender, if
required), to be applied against the Borrower Obligations, whether matured or
unmatured, in such order as the Lender may determine.

            2.4 Amendments, etc. with respect to the Borrower Obligations. Each
Guarantor shall remain obligated hereunder notwithstanding that, without any
reservation of rights against any Guarantor and without notice to or further
assent by any Guarantor, any demand for payment of any of the Borrower
Obligations made by the Lender may be rescinded by the Lender and any of the
Borrower Obligations continued, and the Borrower Obligations, or the liability
of any other Person upon or for any part thereof, or any collateral security or
guarantee therefor or right of offset with respect thereto, may, from time to
time, in whole or in part, be renewed, extended, amended, modified, accelerated,
compromised, waived, surrendered or released by the Lender, and the Credit
Agreement and the other Loan Documents and any other documents executed and
delivered in connection therewith may be amended, modified, supplemented,
restated or terminated, in whole or in part, as the Lender may deem advisable
from time to time, and any collateral security, guarantee or right of offset at
any time held by the Lender for the payment of the Borrower Obligations may be
sold, exchanged, waived, surrendered or released. The Lender shall have no
obligation to protect, secure, perfect or insure any Lien at any time held by it
as security for the Borrower Obligations or for the guarantee contained in this
Section 2 or any property subject thereto.

            2.5 Guarantee Absolute and Unconditional. Each Guarantor waives any
and all notice of the creation, renewal, extension or accrual of any of the
Borrower Obligations and notice of or proof of reliance by the Lender upon the
guarantee contained in this Section 2 or acceptance of the guarantee contained
in this Section 2; the Borrower Obligations, and any of them, shall conclusively
be deemed to have been created, contracted or incurred, or renewed, extended,
amended or waived, in reliance upon the guarantee contained in this Section 2;
and all dealings between the Borrower and any of the Guarantors, on the one
hand, and the Lender, on the other hand, likewise shall be conclusively presumed
to have been had or consummated in reliance upon the guarantee contained in this
Section 2. Each Guarantor waives diligence, presentment, protest, demand for
payment and notice of default or nonpayment to or upon the

                                        7
<PAGE>   12
Borrower or any of the Guarantors with respect to the Borrower Obligations. Each
Guarantor understands and agrees that the guarantee contained in this Section 2
shall be construed as a continuing, absolute and unconditional guarantee of
payment without regard to (a) the validity or enforceability of the Credit
Agreement or any other Loan Document, any of the Borrower Obligations or any
other collateral security therefor or guarantee or right of offset with respect
thereto at any time or from time to time held by the Lender, (b) any defense,
set-off or counterclaim (other than a defense of payment or performance) which
may at any time be available to or be asserted by the Borrower or any other
Person against the Lender, or (c) any other circumstance whatsoever (with or
without notice to or knowledge of the Borrower or such Guarantor) which
constitutes, or might be construed to constitute, an equitable or legal
discharge of the Borrower for the Borrower Obligations, or of such Guarantor
under the guarantee contained in this Section 2, in bankruptcy or in any other
instance. When making any demand hereunder or otherwise pursuing its rights and
remedies hereunder against any Guarantor, the Lender may, but shall be under no
obligation to, make a similar demand on or otherwise pursue such rights and
remedies as it may have against the Borrower, any other Guarantor or any other
Person or against any collateral security or guarantee for the Borrower
Obligations or any right of offset with respect thereto, and any failure by the
Lender to make any such demand, to pursue such other rights or remedies or to
collect any payments from the Borrower, any other Guarantor or any other Person
or to realize upon any such collateral security or guarantee or to exercise any
such right of offset, or any release of the Borrower, any other Guarantor or any
other Person or any such collateral security, guarantee or right of offset,
shall not relieve any Guarantor of any obligation or liability hereunder, and
shall not impair or affect the rights and remedies, whether express, implied or
available as a matter of law, of the Lender against any Guarantor. For the
purposes hereof "demand" shall include the commencement and continuance of any
legal proceedings.

            2.6 Reinstatement. The guarantee contained in this Section 2 shall
continue to be effective, or be reinstated, as the case may be, if at any time
payment, or any part thereof, of any of the Borrower Obligations is rescinded or
must otherwise be restored or returned by the Lender upon the insolvency,
bankruptcy, dissolution, liquidation or reorganization of the Borrower or any
Guarantor, or upon or as a result of the appointment of a receiver, intervenor
or conservator of, or trustee or similar officer for, the Borrower or any
Guarantor or any substantial part of its property, or otherwise, all as though
such payments had not been made.

            2.7 Payments. Each Guarantor hereby guarantees that payments
hereunder will be paid to the Lender without set-off or counterclaim in Dollars
at the office of the Lender located at c/o Harman International Industries, 8500
Balboa Blvd., Northridge, California 91329.

                      SECTION 3. GRANT OF SECURITY INTEREST

            Each Grantor hereby assigns and transfers to the Lender, and hereby
grants to the Lender, a security interest in, all of the following property now
owned or at any time hereafter acquired by such Grantor or in which such Grantor
now has or at any time in the future may acquire any right, title or interest
(collectively, the "Collateral"), as collateral security for the prompt and
complete payment and performance when due (whether at the stated maturity, by
acceleration or otherwise) of such Grantor's Obligations,:

Subsidiary Voting Stock of each relevant Issuer.

            (b) All the shares of the Pledged Stock have been duly and validly
issued and are fully paid and nonassessable.

            (c) Each of the Pledged Notes constitutes the legal, valid and

accordance with its terms, subject to the effects of bankruptcy, insolvency,
fraudulent conveyance, reorganization, moratorium and other similar laws

principles (whether considered in a proceeding in equity or at law) and an
implied covenant of good faith and fair dealing.

            (d) Such Grantor is the record and beneficial owner of, and has good
and marketable title to, the Investment Property pledged by it hereunder, free

            4.10 Parent Representations. In the case of the Parent:

corporation and in good standing under the laws of each jurisdiction where its
ownership, lease or operation of property or the conduct of its business

aggregate, reasonably be expected to have a material adverse effect on the
business, condition (financial or otherwise), operations, prospects or property
of the Parent and its Subsidiaries taken as a whole.

            (b) The Parent has the corporate power and authority, and the legal
right, to make, deliver and perform the Loan Documents to which it is a party
and has taken all necessary corporate action to authorize the execution,
delivery and performance of the Loan Documents to which it is a party. No
consent or authorization of, filing with, notice to or other act by or in
respect of, any Governmental Authority or any other Person is required in
connection with the execution, delivery, performance, validity or enforceability
of the Loan Documents to which the

                                       11
<PAGE>   16
Parent is a party. This Agreement has been, and each other Loan Document to
which it is a party will be, duly executed and delivered on behalf of the
Parent. This Agreement constitutes, and each other Loan Document to which it is
a party when executed and delivered will constitute, a legal, valid and binding
obligation of the Parent enforceable against the Parent in accordance with its
terms, subject to the effects of bankruptcy, insolvency, reorganization,
moratorium and other similar laws relating to or affecting creditors' rights
generally, and general equitable principles (whether considered in a proceeding
in equity or at law).

            (c) The execution, delivery and performance of the Loan Documents to
which the Parent is a party will not violate any Requirement of Law or
Contractual Obligation of the Parent or of any of its Subsidiaries and will not
result in, or require, the creation or imposition of any Lien on any of its or
their respective properties or revenues pursuant to any such Requirement of Law
or Contractual Obligation (other than pursuant to this Agreement).

            (d) No litigation, investigation or proceeding of or before any
arbitrator or Governmental Authority is pending or, to the knowledge of the
Parent, threatened by or against the Parent or any of its Subsidiaries or
against any of its or their respective properties or revenues with respect to
any of the Loan Documents or any of the transactions contemplated hereby or
thereby.

            (e) The Parent has good record and marketable title in fee simple
to, or a valid leasehold interest in, all its real property, and good title to,
or a valid leasehold interest in, all its other property, and none of such
property is subject to any Lien of any nature whatsoever except the Excluded
Real Property.

            (f) The Parent has filed or caused to be filed all tax returns
which, to the knowledge of the Parent, are required to be filed and has paid all
taxes shown to be due and payable on said returns or on any assessments made
against it or any of its property and all other taxes, fees or other charges
imposed on it or any of its property by any Governmental Authority (other than
any the amount or validity of which are currently being contested in good faith
by appropriate proceedings and with respect to which reserves in conformity with
GAAP have been provided on the books of the Parent); no tax Lien has been filed,
and, to the knowledge of the Parent, no claim is being asserted, with respect to
any such tax, fee or other charge.

            (g) The balance sheets of the Parent as at December 31, 1998 and
December 31, 1999 and the related statements of income and of cash flows for the
fiscal years ended on each such date, reported on by Deloitte & Touche LLP,
copies of which have heretofore been furnished to the Lender, are complete and
correct and present fairly the financial condition of the Parent as at such
dates, and the results of its operations and its cash flow for the fiscal years
then ended. The unaudited balance sheet of the Parent as at March 31, 2000 and
the related unaudited statement of income and of cash flow for the three-month
period ended on such date, certified by the President or Chief Financial Officer
of Parent, copies of which have heretofore been furnished to the Lender, are
complete and correct and present fairly the financial condition of the Parent as
at such date, and the results of its operations and its cash flow for the
three-month period then ended (subject to normal year-end audit adjustments).
All such financial statements, including the related schedules and notes
thereto, have been prepared in accordance with GAAP

                                       12
<PAGE>   17
applied consistently throughout the periods involved (except as approved by such
accountants, and as disclosed therein). At the date of the most recent balance
sheet referred to above, the Parent had no material contingent liability or
liability for taxes, or any long-term lease or unusual forward or long-term
commitment, including, without limitation, any interest rate or foreign currency
swap or exchange transaction or other financial derivative, which is not
reflected in the foregoing statements or in the notes thereto. During the period
from December 31, 1999, to and including the date hereof there has been no sale,
transfer or other disposition by the Parent of any material part of its business
or property and no purchase or other acquisition of any business or property
(including any Capital Stock of any other Person) material in relation to the
financial condition of the Parent at December 31, 1999 (except as contemplated
by the Asset Sale Agreement).

                              SECTION 5. COVENANTS

            Each Grantor covenants and agrees with the Lender that, from and
after the date of this Agreement until the Obligations shall have been paid in
full:

            5.1 Delivery of Instruments, Certificated Securities and Chattel
Paper. If any amount payable under or in connection with any of the Collateral
shall be or become evidenced by any Instrument, Certificated Security or Chattel
Paper, such Instrument, Certificated Security or Chattel Paper shall be
immediately delivered to the Lender, duly indorsed in a manner satisfactory to
the Lender, to be held as Collateral pursuant to this Agreement.

            5.2 Maintenance of Insurance. (a) Such Grantor will maintain, with
financially sound and reputable companies, insurance policies (i) insuring the
Inventory, Equipment and Vehicles against loss by fire, explosion, theft and
such other casualties as may be reasonably satisfactory to the Lender and (ii)
insuring such Grantor and the Lender against liability for personal injury and
property damage relating to such Inventory, Equipment and Vehicles, such
policies to be in such form and amounts and having such coverage as may be
reasonably satisfactory to the Lender.

            (b) All such insurance shall (i) provide that no cancellation,
material reduction in amount or material change in coverage thereof shall be
effective until at least 30 days after receipt by the Lender of written notice
thereof, (ii) name the Lender as insured party or loss payee, (iii) if
reasonably requested by the Lender, include a breach of warranty clause and (iv)
be reasonably satisfactory in all other respects to the Lender.

            (c) The Borrower shall deliver to the Lender a report of a reputable
insurance broker with respect to such insurance substantially concurrently with
each delivery of the Borrower's audited annual financial statements and such
supplemental reports with respect thereto as the Lender may from time to time
reasonably request.

            5.3 Payment of Obligations. Such Grantor will pay and discharge or
otherwise satisfy at or before maturity or before they become delinquent, as the
case may be, all taxes, assessments and governmental charges or levies imposed
upon the Collateral or in respect of income or profits therefrom, as well as all
claims of any kind (including, without limitation,

                                       13
<PAGE>   18
claims for labor, materials and supplies) against or with respect to the
Collateral, except that no such charge need be paid if the amount or validity
thereof is currently being contested in good faith by appropriate proceedings,
reserves in conformity with GAAP with respect thereto have been provided on the
books of such Grantor and such proceedings could not reasonably be expected to
result in the sale, forfeiture or loss of any material portion of the Collateral
or any interest therein.

            5.4 Maintenance of Perfected Security Interest; Further
Documentation. (a) Such Grantor shall maintain the security interest created by
this Agreement as a perfected security interest having at least the priority
described in Section 4.2 and shall defend such security interest and the
priority thereof against the claims and demands of all Persons whomsoever.

            (b) Such Grantor will furnish to the Lender from time to time
statements and schedules further identifying and describing the assets and
property of such Grantor and such other reports in connection therewith as the
Lender may reasonably request, all in reasonable detail.

            (c) At any time and from time to time, upon the written request of
the Lender, and at the sole expense of such Grantor, such Grantor will promptly
and duly execute and deliver, and have recorded, such further instruments and
documents and take such further actions as the Lender may reasonably request for
the purpose of obtaining or preserving the full benefits of this Agreement and
of the rights and powers herein granted, including, without limitation, (i)
filing any financing or continuation statements under the Uniform Commercial
Code (or other similar laws) in effect in any jurisdiction with respect to the
security interests created hereby and (ii) in the case of Investment Property,
Deposit Accounts and any other relevant Collateral, taking any actions necessary
to enable the Lender to obtain "control" (within the meaning of the applicable
Uniform Commercial Code) with respect thereto.

            5.5 Changes in Locations, Name, etc. Such Grantor will not, except
upon 15 days' prior written notice to the Lender and delivery to the Lender of
(a) all additional executed financing statements and other documents reasonably
requested by the Lender to maintain the validity, perfection and priority of the
security interests provided for herein and (b) if applicable, a written
supplement to Schedule 5 showing any additional location at which Inventory or
Equipment shall be kept:

            (i) permit any of the Inventory or Equipment to be kept at a
      location other than those listed on Schedule 5;

            (ii) change its jurisdiction of organization or the location of its
      chief executive office or sole place of business from that referred to in
      Section 4.3; or

            (iii) change its name, identity or corporate structure to such an
      extent that any financing statement filed by the Lender in connection with
      this Agreement would become misleading.

                                       14
<PAGE>   19
            5.6 Notices. Such Grantor will advise the Lender promptly, in
reasonable detail, of:

            (a) any Lien (other than security interests created hereby or Liens
permitted under the Credit Agreement) on any of the Collateral which would
adversely affect the ability of the Lender to exercise any of its remedies
hereunder;

            (b) the occurrence of any other event which could reasonably be
expected to have a material adverse effect on the aggregate value of the
Collateral or on the security interests created hereby; and

            (c) the occurrence of any Default or Event of Default.

            5.7 Investment Property. (a) If such Grantor shall become entitled
to receive or shall receive any stock certificate (including, without
limitation, any certificate representing a stock dividend or a distribution in
connection with any reclassification, increase or reduction of capital or any
certificate issued in connection with any reorganization), option or rights in
respect of the Capital Stock of any Issuer, whether in addition to, in
substitution of, as a conversion of, or in exchange for, any shares of the
Pledged Stock, or otherwise in respect thereof, such Grantor shall accept the
same as the agent of the Lender, hold the same in trust for the Lender and
deliver the same forthwith to the Lender in the exact form received, duly
indorsed by such Grantor to the Lender, if required, together with an undated
stock power covering such certificate duly executed in blank by such Grantor and
with, if the Lender so requests, signature guaranteed, to be held by the Lender,
subject to the terms hereof, as additional collateral security for the
Obligations. Any sums paid upon or in respect of the Investment Property upon
the liquidation or dissolution of any Issuer shall be paid over to the Lender to
be held by it hereunder as additional collateral security for the Obligations,
and in case any distribution of capital shall be made on or in respect of the
Investment Property or any property shall be distributed upon or with respect to
the Investment Property pursuant to the recapitalization or reclassification of
the capital of any Issuer or pursuant to the reorganization thereof, the
property so distributed shall, unless otherwise subject to a perfected security
interest in favor of the Lender, be delivered to the Lender to be held by it
hereunder as additional collateral security for the Obligations. If any sums of
money or property so paid or distributed in respect of the Investment Property
shall be received by such Grantor, such Grantor shall, until such money or
property is paid or delivered to the Lender, hold such money or property in
trust for the Lender, segregated from other funds of such Grantor, as additional
collateral security for the Obligations.

            (b) Without the prior written consent of the Lender, such Grantor
will not (i) vote to enable, or take any other action to permit, any Issuer to
issue any stock or other equity securities of any nature or to issue any other
securities convertible into or granting the right to purchase or exchange for
any stock or other equity securities of any nature of any Issuer, (ii) sell,
assign, transfer, exchange, or otherwise dispose of, or grant any option with
respect to, the Investment Property or Proceeds thereof (except pursuant to a
transaction expressly permitted by the Credit Agreement), (iii) create, incur or
permit to exist any Lien or option in favor of, or any claim of any Person with
respect to, any of the Investment Property or Proceeds thereof, or any interest
therein, except for the security interests created by this Agreement or (iv)
enter into any

                                       15
<PAGE>   20
agreement or undertaking restricting the right or ability of such Grantor or the
Lender to sell, assign or transfer any of the Investment Property or Proceeds
thereof.

            (c) In the case of each Grantor which is an Issuer, such Issuer
agrees that (i) it will be bound by the terms of this Agreement relating to the

                                       16
<PAGE>   21
            (d) Such Grantor (either itself or through licensees approved by the

and substance satisfactory to the Lender under each lease, warehouse agreement
or similar agreement to which such Grantor is a party. If any Collateral is at
any time in the possession or control of any warehouseman, bailee or any of the
agents or processors of any Grantor, such Grantor shall notify such
warehouseman, bailee, agent or processor of the security interests created
hereby and to hold all such Collateral for the Lender's account subject to the
Lender's instructions.

            5.13 Financial Statements. The Parent shall furnish to the Lender:

            (a) as soon as available, but in any event within 90 days after the
end of each fiscal year of the Parent, a copy of the audited consolidated

such month and the related unaudited consolidated statements of income and of
cash flows for such month and the portion of the fiscal year through the end of

                                       18
<PAGE>   23
All such financial statements shall be complete and correct in all material
respects and shall be prepared in reasonable detail and in accordance with GAAP
applied consistently throughout the periods reflected therein and with prior
periods (except as approved by such accountants or officer, as the case may be,
and disclosed therein).

            5.14 Mandatory Prepayment. If the Parent or any of its Subsidiaries
(other than the Borrower or any of its Subsidiaries as to which Section 3.3(b)
of the Credit Agreement is applicable) (i) receives Net Cash Proceeds from the
issuance or incurrence of any Indebtedness (other than Indebtedness not in
excess of $100,000 in the aggregate), (ii) receives Net Cash Proceeds from the
issuance of Capital Stock or from any capital contribution (other than capital

such Net Cash Proceeds in accordance with Section 3.3(c) of the Credit
Agreement. Notwithstanding anything to the contrary contained in this Section
5.14, this Section shall not apply to the exercise by C. Jayson Brentlinger of
options to purchase up to 671,500 shares of Common Stock, par value $0.10 of the
Parent, which options existed as of the date hereof.

                         SECTION 6. REMEDIAL PROVISIONS

            6.1 Certain Matters Relating to Receivables. (a) The Lender shall
have the right to make test verifications of the Receivables in any manner and
through any medium that it reasonably considers advisable, and each Grantor
shall furnish all such assistance and information as the Lender may require in
connection with such test verifications. At any time and from time to time, upon
the Lender's request and at the expense of the relevant Grantor, such Grantor
shall cause independent public accountants or others satisfactory to the Lender
to furnish to the Lender reports showing reconciliations, aging and test
verifications of, and trial balances for, the Receivables.

            (b) The Lender hereby authorizes each Grantor to collect such
Grantor's Receivables, subject to the Lender's direction and control, and the
Lender may curtail or terminate said authority at any time after the occurrence
and during the continuance of an Event of Default, provided that all times after
the date hereof all Receivables of the Borrower shall be deposited by the
Borrower, immediately upon receipt, into the Lockbox Account on the terms and
conditions contained in the Lockbox Agreement. If required by the Lender at any
time after the occurrence and during the continuance of an Event of Default, any
payments of Receivables, when collected by any Grantor, (i) shall be forthwith
(and, in any event, within two Business Days) deposited by such Grantor in the
exact form received, duly indorsed by such Grantor to the Lender if required, in
a Collateral Account maintained under the sole dominion and control of the
Lender, subject to withdrawal by the Lender only as provided in Section 6.5, and
(ii) until so turned over, shall be held by such Grantor in trust for the
Lender, segregated from other funds of such Grantor. Each such deposit of
Proceeds of Receivables shall be accompanied by a report identifying in
reasonable detail the nature and source of the payments included in the deposit.

                                       19
<PAGE>   24
            (c) At the Lender's request, each Grantor shall deliver to the
Lender all original and other documents evidencing, and relating to, the
agreements and transactions which gave rise to the Receivables, including,
without limitation, all original orders, invoices and shipping receipts.

            6.2 Communications with Obligors; Grantors Remain Liable. (a) The
Lender in its own name or in the name of others may at any time after the
occurrence and during the continuance of an Event of Default communicate with
obligors under the Receivables to verify with them to the Lender's satisfaction
the existence, amount and terms of any Receivables.

            (b) Upon the request of the Lender at any time after the occurrence
and during the continuance of an Event of Default, each Grantor shall notify
obligors on the Receivables that the Receivables have been assigned to the
Lender and that payments in respect thereof shall be made directly to the
Lender.

            (c) Anything herein to the contrary notwithstanding, each Grantor
shall remain liable under each of the Receivables to observe and perform all the
conditions and obligations to be observed and performed by it thereunder, all in
accordance with the terms of any agreement giving rise thereto. The Lender shall
have no obligation or liability under any Receivable (or any agreement giving
rise thereto) by reason of or arising out of this Agreement or the receipt by
the Lender of any payment relating thereto, nor shall the Lender be obligated in
any manner to perform any of the obligations of any Grantor under or pursuant to
any Receivable (or any agreement giving rise thereto), to make any payment, to
make any inquiry as to the nature or the sufficiency of any payment received by
it or as to the sufficiency of any performance by any party thereunder, to
present or file any claim, to take any action to enforce any performance or to
collect the payment of any amounts which may have been assigned to it or to
which it may be entitled at any time or times.

            6.3 Pledged Stock. (a) Unless an Event of Default shall have
occurred and be continuing and the Lender shall have given notice to the
relevant Grantor of the Lender's intent to exercise its corresponding rights
pursuant to Section 6.3(b), each Grantor shall be permitted to receive all cash
dividends paid in respect of the Pledged Stock and all payments made in respect
of the Pledged Notes, in each case paid in the normal course of business of the
relevant Issuer and consistent with past practice, to the extent permitted in
the Credit Agreement, and to exercise all voting and corporate rights with
respect to the Investment Property; provided, however, that no vote shall be
cast or corporate right exercised or other action taken which, in the Lender's
reasonable judgment, would impair the Collateral or which would be inconsistent
with or result in any violation of any provision of the Credit Agreement, this
Agreement or any other Loan Document.

            (b) If an Event of Default shall occur and be continuing and the
Lender shall give notice of its intent to exercise such rights to the relevant
Grantor or Grantors, (i) the Lender shall have the right to receive any and all
cash dividends, payments or other Proceeds paid in respect of the Investment
Property and make application thereof to the Obligations in such order as the
Lender may determine, and (ii) any or all of the Investment Property shall be
registered in the name of the Lender or its nominee, and the Lender or its
nominee may thereafter exercise (x) all

                                       20
<PAGE>   25
voting, corporate and other rights pertaining to such Investment Property at any
meeting of shareholders of the relevant Issuer or Issuers or otherwise and (y)
any and all rights of conversion, exchange and subscription and any other
rights, privileges or options pertaining to such Investment Property as if it
were the absolute owner thereof (including, without limitation, the right to
exchange at its discretion any and all of the Investment Property upon the
merger, consolidation, reorganization, recapitalization or other fundamental
change in the corporate structure of any Issuer, or upon the exercise by any
Grantor or the Lender of any right, privilege or option pertaining to such
Investment Property, and in connection therewith, the right to deposit and
deliver any and all of the Investment Property with any committee, depositary,
transfer agent, registrar or other designated agency upon such terms and
conditions as the Lender may determine), all without liability except to account
for property actually received by it, but the Lender shall have no duty to any
Grantor to exercise any such right, privilege or option and shall not be
responsible for any failure to do so or delay in so doing.

            (c) Each Grantor hereby authorizes and instructs each Issuer of any
Investment Property pledged by such Grantor hereunder to (i) comply with any
instruction received by it from the Lender in writing that (x) states that an
Event of Default has occurred and is continuing and (y) is otherwise in
accordance with the terms of this Agreement, without any other or further
instructions from such Grantor, and each Grantor agrees that each Issuer shall
be fully protected in so complying, and (ii) unless otherwise expressly
permitted hereby, pay any dividends or other payments with respect to the
Investment Property directly to the Lender.

            6.4 Proceeds to be Turned Over To Lender. In addition to the rights
of the Lender specified in Section 6.1 with respect to payments of Receivables,
if an Event of Default shall occur and be continuing, all Proceeds received by
any Grantor consisting of cash, checks and other near-cash items shall be held
by such Grantor in trust for the Lender, segregated from other funds of such
Grantor, and shall, forthwith upon receipt by such Grantor, be turned over to
the Lender in the exact form received by such Grantor (duly indorsed by such
Grantor to the Lender, if required). All Proceeds received by the Lender
hereunder shall be held by the Lender in a Collateral Account maintained under
its sole dominion and control. All Proceeds while held by the Lender in a
Collateral Account (or by such Grantor in trust for the Lender) shall continue
to be held as collateral security for all the Obligations and shall not
constitute payment thereof until applied as provided in Section 6.5.

            6.5 Application of Proceeds. At such intervals as may be agreed upon
by the Borrower and the Lender, or, if an Event of Default shall have occurred
and be continuing, at any time at the Lender's election, the Lender may apply
all or any part of Proceeds held in any Collateral Account in payment of the
Obligations in such order as the Lender may elect, and any part of such funds
which the Lender elects not so to apply and deems not required as collateral
security for the Obligations shall be paid over from time to time by the Lender
to the Borrower or to whomsoever may be lawfully entitled to receive the same.
Any balance of such Proceeds remaining after the Obligations shall have been
paid in full shall be paid over to the Borrower or to whomsoever may be lawfully
entitled to receive the same.

            6.6 Code and Other Remedies. If an Event of Default shall occur and
be continuing, the Lender may exercise, in addition to all other rights and
remedies granted to it in

                                       21
<PAGE>   26
this Agreement and in any other instrument or agreement securing, evidencing or
relating to the Obligations, all rights and remedies of a secured party under
the New York UCC or any other applicable law. Without limiting the generality of
the foregoing, the Lender, without demand of performance or other demand,
presentment, protest, advertisement or notice of any kind (except any notice
required by law referred to below) to or upon any Grantor or any other Person
(all and each of which demands, defenses, advertisements and notices are hereby
waived), may in such circumstances forthwith collect, receive, appropriate and
realize upon the Collateral, or any part thereof, and/or may forthwith sell,
lease, assign, give option or options to purchase, or otherwise dispose of and
deliver the Collateral or any part thereof (or contract to do any of the
foregoing), in one or more parcels at public or private sale or sales, at any
exchange, broker's board or office of the Lender or elsewhere upon such terms
and conditions as it may deem advisable and at such prices as it may deem best,
for cash or on credit or for future delivery without assumption of any credit
risk. The Lender shall have the right upon any such public sale or sales, and,
to the extent permitted by law, upon any such private sale or sales, to purchase
the whole or any part of the Collateral so sold, free of any right or equity of
redemption in any Grantor, which right or equity is hereby waived and released.
Each Grantor further agrees, at the Lender's request, to assemble the Collateral
and make it available to the Lender at places which the Lender shall reasonably
select, whether at such Grantor's premises or elsewhere. The Lender shall apply
the net proceeds of any action taken by it pursuant to this Section 6.6, after
deducting all reasonable costs and expenses of every kind incurred in connection
therewith or incidental to the care or safekeeping of any of the Collateral or
in any way relating to the Collateral or the rights of the Lender hereunder,
including, without limitation, reasonable attorneys' fees and disbursements, to
the payment in whole or in part of the Obligations, in such order as the Lender
may elect, and only after such application and after the payment by the Lender
of any other amount required by any provision of law, including, without
limitation, Section 9-504(1)(c) of the New York UCC, need the Lender account for
the surplus, if any, to any Grantor. To the extent permitted by applicable law,
each Grantor waives all claims, damages and demands it may acquire against the
Lender arising out of the exercise by them of any rights hereunder. If any
notice of a proposed sale or other disposition of Collateral shall be required
by law, such notice shall be deemed reasonable and proper if given at least 10
days before such sale or other disposition. The Lender shall have the right to
enter the real property leased or owned by each Grantor for the purpose of
exercising any of the foregoing rights or remedies. Each Grantor waives all
rights of marshaling, valuation and appraisal with respect to the Collateral or
any part thereof. For the purpose of enabling the Lender, during the existence
of an Event of Default, to exercise rights and remedies hereunder at such time
as the Lender will be lawfully entitled to exercise such rights and remedies,
and for no other purpose, each Grantor hereby grants to the Lender an
irrevocable, non-exclusive license (exercisable without payment of royalty or
other compensation to such Grantor), until the Obligations are paid in full, to
use, assign, license or sublicense any of the Intellectual Property now owned or
hereafter acquired by such Grantor, wherever the same may be located, including
in such license reasonable access to all media in which any of the licensed
items may be recorded or stored and to all computer programs used for the
compilation or printout thereof.

            6.7 Registration Rights. (a) If the Lender shall determine to
exercise its right to sell any or all of the Pledged Stock pursuant to Section
6.6, and if in the opinion of the Lender it is necessary or advisable to have
the Pledged Stock, or that portion thereof to be sold, registered under the
provisions of the Securities Act, the relevant Grantor will cause the Issuer
thereof to

                                       22
<PAGE>   27
(i) execute and deliver, and cause the directors and officers of such Issuer to
execute and deliver, all such instruments and documents, and do or cause to be
done all such other acts as may be, in the opinion of the Lender, necessary or
advisable to register the Pledged Stock, or that portion thereof to be sold,
under the provisions of the Securities Act, (ii) use its best efforts to cause
the registration statement relating thereto to become effective and to remain
effective for a period of one year from the date of the first public offering of
the Pledged Stock, or that portion thereof to be sold, and (iii) make all
amendments thereto and/or to the related prospectus which, in the opinion of the
Lender, are necessary or advisable, all in conformity with the requirements of
the Securities Act and the rules and regulations of the Securities and Exchange
Commission applicable thereto. Each Grantor agrees to cause such Issuer to
comply with the provisions of the securities or "Blue Sky" laws of any and all
jurisdictions which the Lender shall designate and to make available to its
security holders, as soon as practicable, an earnings statement (which need not
be audited) which will satisfy the provisions of Section 11(a) of the Securities
Act.

            (b) Each Grantor recognizes that the Lender may be unable to effect
a public sale of any or all the Pledged Stock, by reason of certain prohibitions
contained in the Securities Act and applicable state securities laws or
otherwise, and may be compelled to resort to one or more private sales thereof
to a restricted group of purchasers which will be obliged to agree, among other
things, to acquire such securities for their own account for investment and not
with a view to the distribution or resale thereof. Each Grantor acknowledges and
agrees that any such private sale may result in prices and other terms less
favorable than if such sale were a public sale and, notwithstanding such
circumstances, agrees that any such private sale shall be deemed to have been
made in a commercially reasonable manner. The Lender shall be under no
obligation to delay a sale of any of the Pledged Stock for the period of time
necessary to permit the Issuer thereof to register such securities for public
sale under the Securities Act, or under applicable state securities laws, even
if such Issuer would agree to do so.

            (c) Each Grantor agrees to use its best efforts to do or cause to be
done all such other acts as may be necessary to make such sale or sales of all
or any portion of the Pledged Stock pursuant to this Section 6.7 valid and
binding and in compliance with any and all other applicable Requirements of Law.
Each Grantor further agrees that a breach of any of the covenants contained in
this Section 6.7 will cause irreparable injury to the Lender, that the Lender
has no adequate remedy at law in respect of such breach and, as a consequence,
that each and every covenant contained in this Section 6.7 shall be specifically
enforceable against such Grantor, and such Grantor hereby waives and agrees not
to assert any defenses against an action for specific performance of such
covenants except for a defense that no Event of Default has occurred under the
Credit Agreement.

            6.8 Waiver; Deficiency. Each Grantor waives and agrees not to assert
any rights or privileges which it may acquire under Section 9-112 of the New
York UCC. Each Grantor shall remain liable for any deficiency if the proceeds of
any sale or other disposition of the Collateral are insufficient to pay its
Obligations and the fees and disbursements of any attorneys employed by the
Lender to collect such deficiency.

                              SECTION 7. THE LENDER

                                       23
<PAGE>   28
            7.1 Lender's Appointment as Attorney-in-Fact, etc. (a) Each Grantor
hereby irrevocably constitutes and appoints the Lender and any officer or agent
thereof, with full power of substitution, as its true and lawful
attorney-in-fact with full irrevocable power and authority in the place and
stead of such Grantor and in the name of such Grantor or in its own name, for
the purpose of carrying out the terms of this Agreement, to take any and all
appropriate action and to execute any and all documents and instruments which
may be necessary or desirable to accomplish the purposes of this Agreement, and,
without limiting the generality of the foregoing, each Grantor hereby gives the
Lender the power and right, on behalf of such Grantor, without notice to or
assent by such Grantor, to do any or all of the following:

            (i) in the name of such Grantor or its own name, or otherwise, take
      possession of and indorse and collect any checks, drafts, notes,
      acceptances or other instruments for the payment of moneys due under any
      Receivable or with respect to any other Collateral and file any claim or
      take any other action or proceeding in any court of law or equity or
      otherwise deemed appropriate by the Lender for the purpose of collecting
      any and all such moneys due under any Receivable or with respect to any
      other Collateral whenever payable;

            (ii) in the case of any Intellectual Property, execute and deliver,
      and have recorded, any and all agreements, instruments, documents and
      papers as the Lender may request to evidence the Lender's security
      interest in such Intellectual Property and the goodwill and general
      intangibles of such Grantor relating thereto or represented thereby;

            (iii) pay or discharge taxes and Liens levied or placed on or
      threatened against the Collateral, effect any repairs or any insurance
      called for by the terms of this Agreement and pay all or any part of the
      premiums therefor and the costs thereof;

            (iv) execute, in connection with any sale provided for in Section
      6.6 or 6.7, any indorsements, assignments or other instruments of
      conveyance or transfer with respect to the Collateral; and

            (v) (1) direct any party liable for any payment under any of the
      Collateral to make payment of any and all moneys due or to become due
      thereunder directly to the Lender or as the Lender shall direct; (2) ask
      or demand for, collect, and receive payment of and receipt for, any and
      all moneys, claims and other amounts due or to become due at any time in
      respect of or arising out of any Collateral; (3) sign and indorse any
      invoices, freight or express bills, bills of lading, storage or warehouse

      court of competent jurisdiction to collect the Collateral or any portion
      thereof and to enforce any other right in respect of any Collateral; (5)
      defend any suit, action or proceeding brought against such Grantor with

<PAGE>   29
      term or terms, on such conditions, and in such manner, as the Lender shall
      in its sole discretion determine; and (8) generally, sell, transfer,
      pledge and make any agreement with respect to or otherwise deal with any
      of the Collateral as fully and completely as though the Lender were the
      absolute owner thereof for all purposes, and do, at the Lender's option
      and such Grantor's expense, at any time, or from time to time, all acts
      and things which the Lender deems necessary to protect, preserve or
      realize upon the Collateral and the Lender's security interests therein
      and to effect the intent of this Agreement, all as fully and effectively
      as such Grantor might do.

      Anything in this Section 7.1(a) to the contrary notwithstanding, the
Lender agrees that it will not exercise any rights under the power of attorney
provided for in this Section 7.1(a) unless an Event of Default shall have
occurred and be continuing.

            (b) If any Grantor fails to perform or comply with any of its
agreements contained herein, the Lender, at its option, but without any
obligation so to do, may perform or comply, or otherwise cause performance or
compliance, with such agreement.

            (c) The expenses of the Lender incurred in connection with actions
undertaken as provided in this Section 7.1, together with interest thereon at a
rate per annum equal to the Prime Rate in effect from time to time plus three
percent (3%), from the date of payment by the Lender to the date reimbursed by
the relevant Grantor, shall be payable by such Grantor to the Lender on demand.

            (d) Each Grantor hereby ratifies all that said attorneys shall
lawfully do or cause to be done by virtue hereof. All powers, authorizations and
agencies contained in this Agreement are coupled with an interest and are
irrevocable until this Agreement is terminated and the security interests
created hereby are released.

            7.2 Duty of Lender. The Lender's sole duty with respect to the
custody, safekeeping and physical preservation of the Collateral in its
possession, under Section 9-207 of the New York UCC or otherwise, shall be to
deal with it in the same manner as the Lender deals with similar property for
its own account. Neither the Lender nor any of its officers, directors,
employees or agents shall be liable for failure to demand, collect or realize
upon any of the Collateral or for any delay in doing so or shall be under any
obligation to sell or otherwise dispose of any Collateral upon the request of
any Grantor or any other Person or to take any other action whatsoever with
regard to the Collateral or any part thereof. The powers conferred on the Lender
hereunder are solely to protect the Lender's interests in the Collateral and
shall not impose any duty upon the Lender to exercise any such powers. The
Lender shall be accountable only for amounts that they actually receive as a
result of the exercise of such powers, and neither it nor any of its officers,
directors, employees or agents shall be responsible to any Grantor for any act
or failure to act hereunder, except for their own gross negligence or willful
misconduct.

            7.3 Execution of Financing Statements. Pursuant to Section 9-402 of
the New York UCC and any other applicable law, each Grantor authorizes the
Lender to file or record financing statements and other filing or recording
documents or instruments with respect to the Collateral without the signature of
such Grantor in such form and in such offices as the Lender

                                       25
<PAGE>   30
determines appropriate to perfect the security interests of the Lender under
this Agreement. A photographic or other reproduction of this Agreement shall be
sufficient as a financing statement or other filing or recording document or
instrument for filing or recording in any jurisdiction.

                            SECTION 8. MISCELLANEOUS

            8.1 Amendments in Writing. None of the terms or provisions of this
Agreement may be waived, amended, supplemented, restated or otherwise modified
except pursuant to a written agreement executed by the affected Grantor and the
Lender; provided, however, that any provision of this Agreement imposing
obligations on any Grantor may be waived by the Lender in a written instrument
executed by the Lender.

            8.2 Notices. All notices, requests and demands to or upon the Lender
or any Grantor hereunder shall be effected in the manner provided for in
subsection 9.2 of the Credit Agreement; provided, however, that any such notice,
request or demand to or upon any Guarantor shall be addressed to such Guarantor
at its notice address set forth on Schedule 1.

            8.3 No Waiver by Course of Conduct; Cumulative Remedies. The Lender
shall not by any act (except by a written instrument pursuant to Section 8.1),
delay, indulgence, omission or otherwise be deemed to have waived any right or
remedy hereunder or to have acquiesced in any Default or Event of Default. No
failure to exercise, nor any delay in exercising, on the part of the Lender, any
right, power or privilege hereunder shall operate as a waiver thereof. No single
or partial exercise of any right, power or privilege hereunder shall preclude
any other or further exercise thereof or the exercise of any other right, power
or privilege. A waiver by the Lender of any right or remedy hereunder on any one
occasion shall not be construed as a bar to any right or remedy which the Lender
would otherwise have on any future occasion. The rights and remedies herein
provided are cumulative, may be exercised singly or concurrently and are not
exclusive of any other rights or remedies provided by law.

            8.4 Enforcement Expenses; Indemnification. (a) Each Guarantor agrees
to pay or reimburse the Lender for all its costs and expenses incurred in
collecting against such Guarantor under the guarantee contained in Section 2 or
otherwise enforcing or preserving any rights under this Agreement and the other
Loan Documents to which such Guarantor is a party, including, without
limitation, the fees and disbursements of counsel (including the allocated fees
and expenses of in-house counsel) to each Lender.

            (b) Each Guarantor agrees to pay, and to save the Lender harmless
from, any and all liabilities with respect to, or resulting from any delay in
paying, any and all stamp, excise, sales or other taxes which may be payable or
determined to be payable with respect to any of the Collateral or in connection
with any of the transactions contemplated by this Agreement.

            (c) Each Guarantor agrees to pay, and to save the Lender harmless
from, any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever with respect to the execution, delivery, enforcement, performance and
administration of this Agreement to the extent the Borrower would be required to
do so pursuant to subsection 9.5 of the Credit Agreement.

                                       26
<PAGE>   31
            (d) The agreements in this Section 8.4 shall survive repayment of
the Obligations and all other amounts payable under the Credit Agreement and the
other Loan Documents.

            8.5 Successors and Assigns. This Agreement shall be binding upon the
successors and assigns of each Grantor and shall inure to the benefit of the
Lender and its successors and assigns; provided, however, that no Grantor may
assign, transfer or delegate any of its rights or obligations under this
Agreement without the prior written consent of the Lender.

            8.6 Set-Off. Each Grantor hereby irrevocably authorizes the Lender
at any time and from time to time while an Event of Default pursuant to Section
8.1 of the Credit Agreement shall have occurred and be continuing, without
notice to such Grantor or any other Grantor, any such notice being expressly
waived by each Grantor, to set-off and appropriate and apply any and all
deposits (general or special, time or demand, provisional or final), in any
currency, and any other credits, indebtedness or claims, in any currency, in
each case whether direct or indirect, absolute or contingent, matured or
unmatured, at any time held or owing by the Lender to or for the credit or the
account of such Grantor, or any part thereof in such amounts as the Lender may
elect, against and on account of the obligations and liabilities of such Grantor
to the Lender hereunder and claims of every nature and description of the Lender
against such Grantor, in any currency, whether arising hereunder, under the
Credit Agreement, any other Loan Document or otherwise, as the Lender may elect,
whether or not the Lender has made any demand for payment and although such
obligations, liabilities and claims may be contingent or unmatured. The Lender
shall notify such Grantor promptly of any such set-off and the application made
by the Lender of the proceeds thereof; provided, however, that the failure to
give such notice shall not affect the validity of such set-off and application.
The rights of the Lender under this Section 8.6 are in addition to other rights
and remedies (including, without limitation, other rights of set-off) which the
Lender may have.

            8.7 Counterparts. This Agreement may be executed by one or more of
the parties to this Agreement on any number of separate counterparts (including
by telecopy), and all of said counterparts taken together shall be deemed to
constitute one and the same instrument.

            8.8 Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

            8.9 Section Headings. The Section headings used in this Agreement
are for convenience of reference only and are not to affect the construction
hereof or be taken into consideration in the interpretation hereof.

            8.10 INTEGRATION. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS
REPRESENT THE FINAL AGREEMENT OF THE GRANTORS AND THE LENDER WITH RESPECT TO THE
SUBJECT MATTER HEREOF AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS OR

proceeding relating to this Agreement and the other Loan Documents to which it

            (b) consents that any such action or proceeding may be brought in

shall have been notified pursuant thereto;

            (d) agrees that nothing herein shall affect the right to effect
service of process in any other manner permitted by law or shall limit the right
to sue in any other jurisdiction; and

            (e) waives, to the maximum extent not prohibited by law, any right
it may have to claim or recover in any legal action or proceeding referred to in
this Section any special, exemplary, punitive or consequential damages.

            8.13 Acknowledgments. Each Grantor hereby acknowledges that:

            (a) it has been advised by counsel in the negotiation, execution and
delivery of this Agreement and the other Loan Documents to which it is a party;

            (b) the Lender does not have any fiduciary relationship with or duty
to any Grantor arising out of or in connection with this Agreement or any of the
other Loan Documents, and the relationship between the Grantors, on the one
hand, and the Lender, on the other hand, in connection herewith or therewith is
solely that of debtor and creditor; and

            (c) no joint venture is created hereby or by the other Loan
Documents or otherwise exists by virtue of the transactions contemplated hereby
among the Grantors and the Lender.

the Borrower hereunder and under any Notes, whether on account of principal,
interest, fees, or otherwise, shall be made without set-off, recoupment,
counterclaim or other defense and shall be made prior to 12:00 Noon (New York
City time), on the due date thereof to the Lender at the Lender's Payment
Office, in Dollars and in immediately available funds. Payments received by the
Lender after such time shall be deemed to have been received on the next

than a Business Day, the maturity of such payment shall be extended to the next
succeeding Business Day, and, with respect to payments of principal, interest
thereon shall be payable at the then applicable rate during such extension.

         3.7      Taxes. All payments made by the Borrower under this Agreement
or the Notes shall be made free and clear of, and without deduction or
withholding for or on account of, any present or future income, stamp or other
taxes, levies, imposts, duties, charges, fees, deductions, or withholdings
("Taxes"), now or hereafter imposed, levied, collected, withheld or assessed by
any Governmental Authority, excluding net income taxes and franchise taxes
(imposed in lieu of net income taxes) imposed on the Lender as a result of a
present or former connection between the Lender and the jurisdiction of the
Governmental Authority imposing such tax or any political subdivision or taxing
authority thereof or therein (other than any such connection arising solely from
the Lender having executed, delivered or performed its obligations or received a
payment under, or enforced, this Agreement or any Note) (any such non-excluded
Taxes, "Non-Excluded Taxes"). If any Taxes are required to be withheld from any
amounts payable to the Lender hereunder or under any Note, (a) the Borrower
shall withhold and deduct any such Taxes from such amounts, (b) the Borrower
shall pay or deposit with the appropriate taxing authority in a timely manner
the full amount of Taxes so withheld or deducted, (c) the Borrower shall
promptly send to the Lender a certified copy of an original official receipt
received by the Borrower (or other documentation reasonably acceptable to the
Lender) showing payment thereof, and (d) if such Taxes are Non-Excluded Taxes,
the amounts so payable to the Lender shall be increased to the extent necessary
to yield to the Lender (after payment of all Non-Excluded Taxes) interest or any
such other amounts payable hereunder at the rates or in the amounts specified in
this Agreement. If the Borrower fails to pay any Non-Excluded Taxes when due to
the appropriate taxing authority or fails to remit to the Lender the required
receipts or other required documentary evidence, the Borrower shall indemnify
the Lender for any incremental taxes, interest or penalties that may become
payable by the Lender as a result of any such failure. The agreements in this
Section 3.7 shall survive the termination of this Agreement and the payment of
the Notes and all other amounts payable hereunder.

                    SECTION 5. REPRESENTATIONS AND WARRANTIES

         To induce the Lender to enter into this Agreement and make the
extension of credit hereunder, the Borrower hereby represents and warrants to
the Lender that:

         5.1      Financial Condition. The Consolidated pro forma balance sheets
of the Borrower and its Subsidiaries as at March 31, 2000, and the related
Consolidated pro forma statements of income and cash flows of the Borrower and
its Subsidiaries for the twelve months then ended, certified by a Responsible
Officer of the Borrower, copies of which have been furnished to the Lender,
fairly present the Consolidated pro forma financial condition of the Borrower
and its Subsidiaries as at such date and the Consolidated pro forma results of
operations of the Borrower and its Subsidiaries for the period ended on such
date, in each case giving effect to the Asset Purchase and the other
transactions contemplated by the Asset Sale Agreement, all prepared in
accordance with the requirements of Regulation S-X under the Securities Act
applicable to a registration statement under the Securities Act on Form S-1.
Except for the Asset Sale Agreement and the transactions and obligations arising
under the Asset Sale Agreement, Borrower, as of the date hereof, does not
conduct business or own any assets, and has not incurred any Indebtedness,
liabilities or other obligations.

         5.2      Solvency. As of the Closing Date, after giving effect to the
transactions contemplated by the Loan Documents and the Asset Sale Agreement,
the Borrower and its Subsidiaries will each be Solvent.

         5.3      Corporate Existence; Compliance with Law. The Borrower and
each of its Subsidiaries (a) is duly organized, validly existing and in good
standing under the laws of the jurisdiction of its organization, (b) has the
corporate power and authority (including all governmental licenses, permits and
other approvals), and the legal right, to own and operate its property, to lease
the property it operates as lessee and to conduct the business in which it is
currently engaged, (c) is duly qualified as a foreign corporation and in good
standing under the laws of each jurisdiction where its ownership, lease or
operation of property or the conduct of its business requires such qualification
except to the extent its failure to be so qualified and/or in good standing
could not reasonably be expected to have a Material Adverse Effect, and (d) is
in compliance with all Requirements of Law except to the extent that the failure
to comply therewith could not, in the aggregate, reasonably be expected to have
a Material Adverse Effect.

         5.4      Corporate Power; Authorization; Enforceable Obligations. Each
Loan Party has the corporate power and authority, and the legal right, to
execute, deliver and perform the Loan Documents to which it is a party and has
taken all necessary corporate action to authorize the execution, delivery and
performance of the Loan Documents to which it is a party. No consent or
authorization of, filing with, notice to or other act by or in respect of, any
Governmental Authority or any other Person is required in connection with the
execution, delivery, performance, validity or enforceability of the Loan
Documents other than filings and recordings to perfect the Liens created by the
Security Documents. Each Loan Document has been duly executed and delivered on
behalf of each Loan Party thereto. This Agreement constitutes, and each other
Loan Document when executed and delivered, will constitute, a legal, valid and
binding obligation of each Loan Party thereto enforceable against each such Loan
Party in

                                       17
<PAGE>   22
accordance with its terms, subject to the effects of bankruptcy, insolvency,
reorganization, moratorium and other similar laws relating to or affecting
creditors' rights generally and general equitable principles (whether considered
in a proceeding in equity or at law).

         5.5      No Legal Bar. The execution, delivery and performance by the
Loan Parties of the Loan Documents will not violate or create a default under
any Requirement of Law or Contractual Obligation of any Loan Party or of any of
its Subsidiaries and will not result in, or require, the creation or imposition
of any Lien, except pursuant to the Security Documents and the Senior Credit
Agreement, on any of its or their respective properties or revenues pursuant to
any such Requirement of Law or Contractual Obligation.

         5.6      No Material Litigation. No litigation, investigation or
proceeding of or before any arbitrator or Governmental Authority is pending or,
to the knowledge of the Borrower, threatened by or against the Borrower or any
of its Subsidiaries or against any of its or their respective properties or
revenues (a) with respect to any of the Loan Documents or the Asset Sale
Agreement or any of the transactions contemplated hereby or thereby or (b) which
could reasonably be expected to have a Material Adverse Effect.

         5.7      No Default. Neither the Borrower nor any of its Subsidiaries
is in default under or with respect to any of its Contractual Obligations in any
respect which could reasonably be expected to have a Material Adverse Effect. No
Default or Event of Default has occurred and is continuing.

         5.8      Ownership of Property; Liens. The Borrower and each of its
Subsidiaries has good record and marketable title in fee simple to, or a valid
leasehold interest in, all its real property, and good title to, or a valid
leasehold interest in, all its other property, and none of such property is
subject to any Lien except as permitted by Section 7.2. Schedule 5.8 sets forth
a true and complete list of all real property owned or leased by the Borrower
and its Subsidiaries as of the date hereof.

         5.9      Intellectual Property. The Borrower and each of its
Subsidiaries owns, or is licensed to use, all Intellectual Property necessary to
conduct of its business as currently conducted. No claim has been asserted and
is pending by any Person challenging or questioning the use of any such
Intellectual Property or the validity or effectiveness of any such Intellectual
Property, nor does the Borrower know of any valid basis for any such claim. The
use of such Intellectual Property by the Borrower and its Subsidiaries does not
infringe on the rights of any Person.

         5.10     No Burdensome Restrictions. No Requirement of Law or
Contractual Obligation of the Borrower or any of its Subsidiaries could
reasonably be expected to have a Material Adverse Effect.

         5.11     Taxes. The Borrower and each of its Subsidiaries has filed or
caused to be filed all tax returns which are required to be filed and has paid
all taxes shown to be due and payable on said returns or on any assessments made
against it or any of its property and all other taxes, fees or other charges
imposed on it or any of its property by any Governmental Authority (other than

                                       18
<PAGE>   23
any such taxes, fees and other charges, the amount or validity of which are
currently being contested in good faith by appropriate proceedings and with
respect to which reserves in conformity with GAAP have been provided on the
books of the Borrower or its Subsidiaries, as the case may be); no tax Lien has
been filed, and no claim is being asserted, with respect to any such tax, fee or
other charge.

         5.12     ERISA. All Plans of the Borrower and its Subsidiaries on the
Closing Date are described on Schedule 5.12. Neither a Reportable Event nor an
"accumulated funding deficiency" (within the meaning of Section 412 of the Code
or Section 302 of ERISA) has occurred during the five-year period prior to the
date on which this representation is made or deemed made with respect to any
Plan and each Plan has complied in all material respects with the applicable
provisions of ERISA and the Code. No termination of a Single Employer Plan has
occurred, and no Lien in favor of the PBGC or a Plan has arisen, during such
five-year period. The present value of all accrued benefits under each Single
Employer Plan (based on those assumptions used to fund such Plans) did not, as
of the last annual valuation date prior to the date on which this representation
is made or deemed made, exceed the value of the assets of such Plan allocable to
such accrued benefits. Neither the Borrower nor any Commonly Controlled Entity
has had a complete or partial withdrawal from any Multiemployer Plan, and
neither the Borrower nor any Commonly Controlled Entity would become subject to
any liability under ERISA if the Borrower or any such Commonly Controlled Entity
were to withdraw completely from all Multiemployer Plans as of the valuation
date most closely preceding the date on which this representation is made or
deemed made. No such Multiemployer Plan is in Reorganization or Insolvent.

         5.13     Investment Company Act; Other Regulations. Neither the
Borrower nor any of its Subsidiaries is an "investment company", or a company
"controlled" by an "investment company", within the meaning of the Investment
Company Act of 1940, as amended. Neither the Borrower nor any of its
Subsidiaries is subject to regulation under any federal or state statute or
regulation (other than Regulation X) which limits its ability to incur
Indebtedness.

         5.14     Subsidiaries. Schedule 5.14 sets forth a complete and accurate
list of all Subsidiaries of the Borrower on the date hereof, showing as of the
date hereof (as to each such Subsidiary), the jurisdiction of its incorporation,
the name, address, telephone number and contact person for the purpose of notice
to such Subsidiary under this Agreement, the number of shares of each class of
its Capital Stock authorized, and the number of shares outstanding, and the
percentage of each such class of its Capital Stock owned (directly or
indirectly) by the Borrower or any of its Subsidiaries and the number of shares
covered by all outstanding options, warrants, rights of conversion or purchase
and similar rights at the date hereof. All of the outstanding Capital Stock of
the Subsidiaries has been validly issued, is fully paid and non-assessable. All
of the Capital Stock of the Subsidiaries owned by the Borrower or one or more of
its Subsidiaries is owned free and clear of all Liens, except those created
under the Security Documents. CRL International, Inc. does not (i) currently
transact business, (ii) have any assets, or (iii) have any outstanding
Indebtedness.

         5.15     No Material Misstatements. The written information, reports,
financial statements, exhibits and schedules furnished by or on behalf of the
Borrower and each other Loan Party to

                                       19
<PAGE>   24
the Lender in connection with the negotiation of any Loan Document or any
document related thereto or included therein or delivered pursuant to the terms
of any Loan Document do not contain and will not contain any material
misstatement of fact and do not omit and will not omit to state any material
fact necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading. It is understood that no
representation or warranty is made concerning the forecasts, estimates, pro
forma information, projections and statements as to anticipated future
performance or conditions (the "Projections"), and the assumptions on which they
were based, contained in any such information, reports, financial statements,
exhibits or schedules, except that, as of the date such Projections were
generated, (a) such Projections were based on the good faith assumptions of the
management of the Borrower and (b) the assumptions on which the Projections were
based were believed by such management to be reasonable. There is no fact known
to the Borrower that could reasonably be expected to have a Material Adverse
Effect that has not been expressly disclosed herein, in the other Loan
Documents, or in any other document, certificate or statement furnished to the
Lender for use in connection with the transactions contemplated hereby and by
the other Loan Documents.

         5.16     Representations and Warranties Contained in the Asset Sale
Agreement. The Asset Sale Agreement has been duly executed and delivered by the
Borrower. As of the Closing Date, the representations and warranties of the
Borrower contained in the Asset Sale Agreement are true and correct.

         5.17     Ownership of the Borrower. All the Capital Stock of the
Borrower is owned by, and as of the Closing Date will be owned by, the Parent,
free and clear of all liens.

         5.18     Collateral. The provisions of each of the Security Documents,
when executed and delivered, will create in favor of and for the benefit of the
Lender, a legal, valid and enforceable security interest in and Lien on all
right, title and interest of each of the Loan Parties which is a party to such
Security Document, in the Collateral described in such Security Document. When
the Security Documents have been executed and when financing statements have
been filed in the offices in the jurisdictions listed in Schedule 5.18, when
appropriate filings have been recorded in the jurisdictions listed in Schedule
5.18 with respect to the Intellectual Property, and when the Pledged Stock and
Pledged Notes (as such terms are defined in the Guarantee and Collateral
Agreement) have been delivered to the Lender, each of the Security Documents
shall create a perfected security interest in and Lien on all right, title and
interest of the Loan Parties, in the Collateral described therein, as security
for the Obligations (as defined in the relevant Security Document), in each case
prior and superior in right to any other Person, except as permitted by Section
7.2.

         5.19     Material Contracts. Schedule 5.19 hereto sets forth as of the
Closing Date a complete and accurate list of all Material Contracts of the
Borrower and its Subsidiaries, showing the parties, subject matter and term
thereof. Each such Material Contract has been duly authorized, executed and
delivered by all parties thereto, has not been amended or otherwise modified, is
in full force and effect and is binding upon and enforceable against all parties
thereto in accordance with its terms, and there exists no default under any
Material Contract by any party thereto.

provided that any notice, request or demand to or upon the Lender shall not be
effective until received.

         9.3      No Waiver; Cumulative Remedies. No failure to exercise and no
delay in exercising, on the part of the Lender, any right, remedy, power or
privilege hereunder or under the other Loan Documents shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, remedy, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, remedy, power or privilege. The rights, remedies,
powers and privileges herein provided are cumulative and not exclusive of any
rights, remedies, powers and privileges provided by law.

         9.4      Survival of Representations and Warranties. All
representations and warranties made hereunder, in the other Loan Documents (or
in any amendment, modification or supplement hereto or thereto) and in any
document, certificate or statement delivered pursuant hereto or in connection
herewith shall survive the execution and delivery of this Agreement and the
making of the Loans hereunder.

         9.5      Payment of Expenses and Taxes; Indemnification. (a) The
Borrower agrees to pay on demand all costs and expenses of the Lender (including
reasonable attorneys' fees and expenses and the cost of internal counsel) in
connection with any Default or Event of Default and the enforcement (whether
through negotiations, legal proceedings or otherwise) of the Loan Documents and
the other documents to be delivered hereunder.

                  (b)      The Borrower agrees to pay, indemnify and hold the
Lender harmless from any and all recording and filing fees and any and all
liabilities with respect to, or resulting from any delay in paying, stamp,
excise and other taxes, if any, which may be payable or determined to be payable
in connection with the execution and delivery of, or consummation or
administration of any of the transactions contemplated by, or any amendment,
supplement or modification of, or any waiver or consent under or in respect of,
this Agreement, the other Loan Documents and any such other documents.

                  (c)      The Borrower agrees to indemnify and hold harmless
the Lender and each of its Affiliates and their respective officers, directors,
employees, agents and advisors (each, an "Indemnified Party") from and against
any and all claims, damages, losses, liabilities, penalties, judgments, suits,
costs (including settlement costs) and expenses (including reasonable attorneys'
fees and expenses and the cost of internal counsel) that may be incurred by or
asserted or awarded against any Indemnified Party, in each case arising out of
or in connection with or by reason of (including in connection with any
investigation, litigation, or proceeding or preparation

                                       34
<PAGE>   39
of defense in connection therewith) the Asset Sale Agreement or the Loan
Documents or any of the transactions contemplated herein or therein (including
any of the foregoing arising from the negligence of the Indemnified Party),
except to the extent such claim, damage, loss, liability, penalty, cost or
expense is found in a final, non-appealable judgment by a court of competent
jurisdiction to have resulted from such Indemnified Party's gross negligence,
bad faith or willful misconduct. In the case of an investigation, litigation or
other proceeding to which the indemnity in this Section 9.5(c) applies, such
indemnity shall be effective whether or not such investigation, litigation or
proceeding is brought by the Borrower, its directors, shareholders or creditors
or an Indemnified Party or any other Person or any Indemnified Party is
otherwise a party thereto and whether or not the transactions contemplated
hereby are consummated. The Borrower agrees not to assert any claim against the
Lender, any of its Affiliates, or any of their respective directors, officers,
employees, attorneys, agents and advisers, on any theory of liability, for
special, indirect, consequential or punitive damages arising out of or otherwise
relating to the Loan Documents, any of the transactions contemplated herein or
therein, or the actual or proposed use of the proceeds of the Loans.

                  (d)      Without prejudice to the survival of any other
agreement of the Borrower hereunder, the agreements and obligations of the
Borrower contained in this Section 9.5 shall survive the payment in full of the
Loans and all other Obligations.

         9.6      Successors and Assigns. This Agreement shall be binding upon
and inure to the benefit of the Borrower, the Lender and their respective
successors and assigns, except that the Borrower may not assign or transfer any
of its rights or obligations under this Agreement without the prior written
consent of the Lender.

         9.7      Set-off. Upon the occurrence and during the continuance of any
Event of Default, the Lender (and each of its Affiliates) is hereby authorized
at any time and from time to time, to the fullest extent permitted by law, to
set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other indebtedness at any time owing
by the Lender (or any of its Affiliates) to or for the credit or the account of
the Borrower against any and all of the Obligations of the Borrower held by the
Lender, irrespective of whether the Lender shall have made any demand under this
Agreement or any other relevant Loan Document and although such Obligations may
be unmatured. The Lender agrees promptly to notify the Borrower after any such
set-off and application made by the Lender; provided, however, that the failure
to give notice shall not affect the validity of such set-off and application.
The rights of the Lender under this Section 9.7 are in addition to other rights
and remedies (including other rights of set-off) that the Lender may have.

         9.8      Counterparts. This Agreement may be executed by one or more of
the parties to this Agreement on any number of separate counterparts (including
by facsimile transmission), and all of said counterparts taken together shall be
deemed to constitute one and the same instrument. Manual delivery of an executed
counterpart of a signature page to this Agreement shall be effective as delivery
of an original executed counterpart of this Agreement.

         9.9      Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any

                                       35
<PAGE>   40
such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

         9.10     INTEGRATION. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS
REPRESENT THE FINAL AGREEMENT OF THE BORROWER AND THE LENDER WITH RESPECT TO THE
SUBJECT MATTER HEREOF, AND THERE ARE NO PROMISES, UNDERTAKINGS, REPRESENTATIONS
OR WARRANTIES BY THE LENDER RELATIVE TO THE SUBJECT MATTER HEREOF NOT EXPRESSLY
SET FORTH OR REFERRED TO HEREIN OR IN THE OTHER LOAN DOCUMENTS.

         9.11     GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS
OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN

NEW YORK GENERAL OBLIGATIONS LAW.

         9.12     Submission To Jurisdiction; Waivers. The Borrower hereby
irrevocably and unconditionally:

         (a)      submits for itself and its property in any legal action or
proceeding relating to this Agreement and the other Loan Documents to which it
is a party, or for recognition and enforcement of any judgement in respect
thereof, to the non-exclusive general jurisdiction of the Courts of the State of
New York, the courts of the United States of America for the Southern District
of New York, and appellate courts from any thereof;

         (b)      consents that any such action or proceeding may be brought in
such courts and waives any objection that it may now or hereafter have to the
venue of any such action or proceeding in any such court or that such action or
proceeding was brought in an inconvenient court and agrees not to plead or claim
the same;

         (c)      agrees that service of process in any such action or
proceeding may be effected by mailing a copy thereof by registered or certified
mail (or any substantially similar form of mail), postage prepaid, to the
Borrower at the addresses set forth pursuant to Section 9.2 or at such other
address of which the Lender shall have been notified pursuant thereto; and

         (d)      agrees that nothing herein shall affect the right to effect
service of process in any other manner permitted by law or shall limit the right
to sue in any other jurisdiction.

         9.13     Acknowledgments. The Borrower hereby acknowledges that:

         (a)      it has been advised by counsel in the negotiation, execution
and delivery of this Agreement and the other Loan Documents;

         (b)      the Lender does not have any fiduciary relationship with or
duty to the Borrower arising out of or in connection with this Agreement or any
of the other Loan Documents, and the

                                       36
<PAGE>   41
relationship between the Lender, on one hand, and the Loan Parties, on the other
hand, in connection herewith or therewith is solely that of debtor and creditor;
and

         (c)      no joint venture is created hereby or by the other Loan
Documents or otherwise exists by virtue of the transactions contemplated hereby
among the Loan Parties and the Lender.

         9.14     WAIVERS OF JURY TRIAL. THE BORROWER AND THE LENDER HEREBY
IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR
PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY
COUNTERCLAIM THEREIN.

         9.15     Confidentiality. The Lender agrees to keep confidential any
information furnished or made available to it by the Borrower pursuant to this
Agreement that is marked confidential; provided that nothing herein shall
prevent the Lender from disclosing such information (a) to any Affiliate of the
Lender, or any officer, director, employee, agent, or advisor of the Lender or
Affiliate of the Lender, (b) as required by any law, rule or regulation, (c)
upon the order of any court or administrative agency, (d) upon the request or
demand of any regulatory agency or authority, (e) that is or becomes available
to the public, (f) in connection with any litigation to which the Lender or any
of its Affiliates may be a party, (g) to the extent necessary in connection with
the exercise of any remedy under this Agreement or any other Loan Document, or
(h) subject to provisions substantially similar to those contained in this
Section 9.15, to any actual or proposed assignee of all or any part of the
Lender's rights and obligations under this Agreement or any other Loan Document.

         9.16     Usury Savings Clause. It is the intention of the parties
hereto to comply with applicable usury laws (now or hereafter enacted);
accordingly, notwithstanding any provision to the contrary in this Agreement,
any Notes, any of the other Loan Documents or any other document related hereto
or thereto, in no event shall this Agreement or any such other document require
the payment or permit the collection of interest in excess of the maximum amount
permitted by such laws. If from any circumstances whatsoever, fulfillment of any
provision of this Agreement, any Notes, any of the other Loan Documents or of
any other document pertaining hereto or thereto, shall involve transcending the
limit of validity prescribed by applicable law for the collection or charging of
interest, then, ipso facto, the obligation to be fulfilled shall be reduced to
the limit of such validity, and if from any such circumstances the Lender shall
ever receive anything of value as interest or deemed interest by applicable law
under this Agreement, any Notes, any of the other Loan Documents or any other
document pertaining hereto or otherwise an amount that would exceed the highest
lawful rate of interest permitted by applicable law, such amount that would be
excessive interest shall be applied to the reduction of the principal amount
owing under the Loans or on account of any other indebtedness of the Borrower,
and not to the payment of interest, or if such excessive interest exceeds the
unpaid balance of principal of such indebtedness, such excess shall be refunded
to the Borrower. In determining whether or not the interest paid or payable with
respect to any indebtedness of the Borrower to the Lender, under any specified
contingency, exceeds the highest lawful rate, the Borrower and the Lender shall,
to the maximum extent permitted by applicable law, (a) characterize any
non-principal payment as an expense, fee or premium rather than as interest, (b)
exclude voluntary prepayments and the effects thereof, (c) amortize, prorate,
allocate and spread the total amount of interest throughout the full term of
such indebtedness so that interest

                                       37
<PAGE>   42
thereon does not exceed the maximum amount permitted by applicable law, and/or
(d) allocate interest between portions of such indebtedness, to the end that no
such portion shall bear interest at a rate greater than that permitted by
applicable law.

         9.17     Senior Financing. In the event that the Borrower obtains
financing on or before September 30, 2000, in a principal amount not to exceed
$4,000,000 (the "Senior Financing"), the Lender will subordinate payment of the
Tranche A Note and the Liens under the Security Documents to the Liens securing
the Senior Financing, provided that:

         (a)      the terms and conditions of the Senior Financing and all
related documentation are satisfactory to the Lender in its sole discretion;

         (b)      the proceeds of the Senior Financing will be used to pay in
full the Tranche B Note; and

         (c)      the Lender will retain, after giving effect to the Senior
Financing, a perfected, first priority security interest in all Capital Stock of
the Borrower as security for the Obligations.
