                                    THE LOANS

                  SECTION 2.01. COMMITMENT. The Lender agrees, on the terms and
conditions hereinafter set forth, to make revolving loans (the "LOANS") to the
Borrower from time to time on any Business Day during the period commencing on
the date hereof and ending on, but excluding, the Final Maturity Date, in an
aggregate principal amount at any time outstanding not to exceed the LESSER of
(i) the amount of the Commitment and (ii) the amount of the Borrowing Base then
in

                                      -20-
<PAGE>

effect. Within the limit of the amount of the Commitment, the Borrower may
borrow, prepay and reborrow Loans pursuant to this Article II.

                  SECTION 2.02. MAKING THE LOANS. The Borrower shall give the
Lender prior written or telecopied notice, in substantially the form of Exhibit
E hereto (a "NOTICE OF BORROWING"), not later than 11:00 a.m. (New York City
time) five Business Days prior to the date of the proposed Loan. Such Notice of
Borrowing shall be irrevocable and shall specify (i) the principal amount of the
proposed Loan, (ii) the use of the proceeds of such proposed Loan and (iii) the
proposed borrowing date, which must be a Business Day. The Lender may act
without liability upon the basis of written or telecopied notice believed by the
Lender in good faith to be from the Borrower (or from any Authorized Officer
thereof designated in writing purportedly from the Borrower to the Lender). Each
Notice of Borrowing shall be irrevocable and binding on the Borrower. Each Loan
shall be made in a minimum amount of $50,000 and shall be in an integral
multiple of $1,000. The Lender will make the proceeds of such Loan available to
the Borrower on the day of the proposed Loan by causing an amount, in
immediately available funds, to be deposited in an account designated by the
Borrower to the Lender at a commercial bank reasonably satisfactory to the
Lender.

                  SECTION 2.03. NOTE; REPAYMENT OF LOANS. (a) All Loans made by
the Lender to the Borrower shall be evidenced by a single Note, duly executed on
behalf of the Borrower, dated the Effective Date, and delivered to and made
payable to the order of the Lender in a principal amount equal to the amount of
the Commitment.

                      (b) The outstanding principal of each Loan shall be due
and payable on the Final Maturity Date.

                      (c) The Borrower agrees to record each Loan on the
Register referred to in Section 10.07(b)(i). Each Loan recorded on the Register
(the "REGISTERED LOAN") may not be evidenced by promissory notes other than the
Note which is a Registered Note (as defined below). Upon the registration of any
Loan, any promissory note (other than a Registered Note) evidencing the same
shall be null and void and shall be returned to the Borrower. The Borrower
agrees, at the request of the Lender, to execute and deliver to Lender a
promissory note in registered form to evidence such Registered Loan (i.e.
containing the registered note language set forth in Exhibits A hereto) and
registered as provided in Section 10.07(b) (a "REGISTERED NOTE"), dated the date
hereof, payable to the Lender and otherwise duly completed. Once recorded on the
Register, the Loan or Loans evidenced by such Note may not be removed from the
Register so long as it remains outstanding, and a Registered Note may not be
exchanged for a promissory note that is not a Registered Note.

                  SECTION 2.04.   INTEREST.

                      (a) LOANS. Each Loan shall bear interest on the principal
amount thereof from time to time outstanding, from the date of such Loan until
such principal amount becomes due, at a rate per annum equal to the greater of
(i) the Reference Rate plus 2% and (ii) 11.50%.


                                      -21-
<PAGE>

                      (b) DEFAULT INTEREST. To the extent permitted by law, upon
the occurrence and during the continuance of an Event of Default, the principal
of, and all accrued and unpaid interest on, all Loans, and all fees, indemnities
or any other Obligations of the Borrower or the other Loan Parties under this
Agreement, the Note and other Loan Documents shall bear interest, from the date
such Event of Default occurred until such Event of Default is cured or waived in
writing in accordance herewith, at a rate per annum equal at all times to the
Post-Default Rate.

                      (c) INTEREST PAYMENT.

                          (i) Interest on each Loan shall be payable in
immediately available funds monthly, in arrears, on the first day of each month
of each year, commencing on the first day of the month following the month in
which such Loan is made and at maturity (whether upon demand, by acceleration or
otherwise).

                          (ii) Interest at the Post-Default Rate shall be
payable on demand.

                          (iii) The Borrower hereby authorizes the Lender to,
and the Lender may, from time to time, charge the Loan Account pursuant to
Section 3.01 with the amount of any interest payment due hereunder.

                      (d) GENERAL. All interest shall be computed on the basis
of a year of 360 days for the actual number of days, including the first day but
excluding the last day, elapsed.

                  SECTION 2.05. OPTIONAL REDUCTION OF COMMITMENT; PREPAYMENT OF
LOANS.

                      (a) OPTIONAL REDUCTION OF COMMITMENT. The Borrower may,
without premium or penalty, reduce the Commitment to an amount (which may be
zero) not less than the sum of (i) the aggregate unpaid principal amount of all
Loans then outstanding and (ii) the aggregate principal amount of all Loans not
yet made as to which a Notice of Borrowing has been given by the Borrower under
Section 2.02. Each such reduction shall be in an amount which is an integral
multiple of $100,000, shall be made by providing not less than three Business
Days' prior written notice to the Lender and shall be irrevocable. Once reduced
the Commitment may not be increased.

                      (b) INTEREST AND FEES. Any prepayment made in connection
with a reduction of the Commitment pursuant to Section 2.05(a) shall be
accompanied by accrued interest on the principal amount being prepaid to the
date of prepayment, and if such prepayment would reduce the amount of the
outstanding Loans to zero at a time when the Commitment has been terminated,
such prepayment shall be accompanied by the payment of the fees accrued to such
date pursuant to Section 2.06.

                  SECTION 2.06.   FEES.

                      (a) COMMITMENT FEE. On the earlier of (i) the Effective
Date and (ii) the date on which the Borrower delivers its written acceptance of
the financing commitment letter of the Lender dated August 23, 2000, the
Borrower shall pay to the Lender a commitment fee (the

                      (c) LOAN SERVICING FEE. From and after the Effective Date

per calendar quarter, payable quarterly in advance on the first day of January,
April, July and October of each year, commencing October 1, 2000.

                      (d) UNUSED LINE FEE. From and after the Effective Date and
until the Final Maturity Date, the Borrower shall pay to the Lender a
non-refundable unused line fee (the "UNUSED LINE FEE") in an amount equal to
 .50% per annum times the difference between (i) the Commitment (as of the first
day of the month for which the Unused Line Fee is being calculated, or in the
case of the initial Unused Line Fee, as of the Effective Date) LESS (ii) the
average amount of Loans that are outstanding during such month, payable monthly
in arrears on the first day of each month, commencing October 1, 2000. The
Unused Line Fee shall be prorated for any portion of a month during which either

                      (e) ANNIVERSARY FEE. From and after the Effective Date and
until, but excluding, the Final Maturity Date, the Borrower shall pay to the
Lender a fee (the "ANNIVERSARY FEE") of $100,000 upon each anniversary of the

anniversary date and shall be nonrefundable.

                      (f) FINANCIAL EXAMINATION, DOCUMENTATION, AND APPRAISAL
FEES. The Borrower shall pay to the Lender the following non-refundable fees:
(A) a field examination fee (the "FIELD EXAMINATION FEE") of $1,500 per day per
examiner, plus reasonable out-of-pocket expenses, for each financial analysis
and examination (i.e., audits) of any Loan Party or the Collateral performed by
personnel employed by the Lender and (B) the actual reasonable charges paid or
incurred by the Lender if it elects to employ the services of one or more third
Persons to perform such financial analyses and examinations (i.e., audits) of
any Loan Party or the Collateral. So long as no Default or Event of Default has
occurred and is continuing, such audits shall be performed not more often than
once each Fiscal Quarter.

                  SECTION 2.07. SECURITIZATION. The Loan Parties hereby
acknowledges that the Lender and any of its Affiliates may sell or securitize
the Loans (a "SECURITIZATION") through the pledge of the Loans as collateral
security for loans to the Lender or its Affiliates or through the sale of the
Loans or the issuance of direct or indirect interests in the Loans, which loans
to the Lender or its Affiliate or direct or indirect interests will be rated by
Moody's, Standard & Poor's or one or more other rating agencies (the "RATING
AGENCIES"). The Loan Parties shall cooperate with the Lender and its Affiliates
to effect the Securitization including, without limitation, by (a) amending this
Agreement and the other Loan Documents, and executing such additional documents,
as reasonably requested by the Lender in connection with the Securitization,
PROVIDED THAT (i) any such amendment or additional documentation does not impose
material

                                      -23-

<PAGE>

additional costs on the Loan Parties and (ii) any such amendment or additional
documentation does not materially adversely affect the rights, or materially
increase the obligations, of the Loan Parties under the Loan Documents or change
or affect in a manner adverse to the Loan Parties the financial terms of the
Loans, (b) providing such information as may be reasonably requested by the
Lender in connection with the rating of the Loans or the Securitization, and (c)
providing in connection with any rating of the Loans a certificate (i) agreeing
to indemnify the Lender and any of its Affiliates, any of the Rating Agencies,
or any party providing credit support or otherwise participating in the
Securitization (collectively, the "SECURITIZATION PARTIES") for any losses,
claims, damages or liabilities (the "LIABILITIES") to which the Lender, its
Affiliates or such Securitization Parties may become subject insofar as the
Liabilities arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any Loan Document or in any
writing delivered by or on behalf of the Loan Parties to the Lender in
connection with any Loan Document or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein, or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading and such indemnity
shall survive any transfer by the Lender or its successors or assigns of the
Loans and (ii) agreeing to reimburse the Lender and any of its Affiliates for
any legal or other expenses reasonably incurred by such Persons in connection
with defending the Liabilities.


                                   ARTICLE III
                         PAYMENTS AND OTHER COMPENSATION

                  SECTION 3.01. PAYMENTS; COMPUTATIONS AND STATEMENTS. The
Borrower will make each payment under this Agreement, the Note and the other
Loan Documents (whether of principal, interest, fees, expense reimbursements or
otherwise) not later than 2:00 p.m. (New York City time) on the day when due, in
lawful money of the United States of America and in immediately available funds,
to the Lender at the Lender Account. All such payments received by the Lender
after 2:00 p.m. (New York City time) on any Business Day will be credited to the
Loan Account on the next succeeding Business Day. All such payments shall be
made by the Borrower without defense, set-off or counterclaim to the Lender. The
Borrower hereby authorizes the Lender to, and the Lender may, from time to time
charge the Loan Account with all Obligations and any other amount due and
payable under any Loan Document to which the Borrower is a party, whether or not
any Event of Default or Default shall have occurred or be continuing or whether
any of the conditions precedent in Section 4.02 have been satisfied. Any amount
charged to the Loan Account shall be deemed a Loan hereunder made by the Lender
to the Borrower. The Borrower confirms that any charges which the Lender may so
make to the Loan Account as herein provided will be made as an accommodation to
the Borrower and solely at the Lender's discretion. It is expressly understood
and agreed by the Borrower that the Lender shall have no responsibility to
inquire into the correctness of the allocation or disposition of the proceeds of
the Loans made to the Borrower in accordance with the payment instructions of
the Borrower, or any fees, costs or expenses for which the Borrower is obligated
under this Agreement. Whenever any payment to be made under any such Loan
Document shall be stated to be due on a day other than a Business Day, such
payment shall be made on the next succeeding Business Day and such extension of
time shall in such case be included in the computation of interest or fees, as
the case may be, PROVIDED that, if


                                      -24-
<PAGE>

any such payment is made by a charge to the Loan Account, such charge may be
made by the Lender on any day, whether or not a Business Day. All computations
of interest and fees shall be made by the Lender on the basis of a year of 360
days for the actual number of days (including the first day but excluding the
last day) occurring in the period for which such interest or fee is payable.
Each determination by the Lender of an interest rate, fees or expense
reimbursement hereunder shall be conclusive and binding for all purposes in the
absence of manifest error.


                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

                  SECTION 5.01. REPRESENTATIONS AND WARRANTIES. The Loan Parties
hereby represent and warrant to the Lender as follows:

                      (a) ORGANIZATION, GOOD STANDING, ETC. Each of the Parent,
the Permitted Subsidiaries and the other Subsidiaries of the Parent (except as

company or limited partnership duly organized, validly existing and in good

and to execute and deliver each Loan Document to which it is a party, and to
consummate the transactions contemplated thereby, and (iii) is duly qualified to
do business and is in good standing in each jurisdiction in which the character
of the properties owned or leased by it or in which the transaction of its
business makes such qualification necessary, except where the failure to so
qualify could not have a Material Adverse Effect.

                      (b) AUTHORIZATION, ETC. The execution, delivery and
performance by each of the Parent and its Subsidiaries of each Loan Document to
which it is or will be a party, (i) have been or, with respect to Subsidiaries
of the Parent formed or acquired hereafter, will be duly authorized by all
necessary action, (ii) do not and will not contravene its charter or by-laws,
its limited liability company or operating agreement or its certificate of
partnership or partnership agreement, as applicable, or any applicable law or
any contractual restriction binding on or otherwise affecting it or any of its
properties, (iii) do not and will not result in or require the creation of any
Lien (other than pursuant to any Loan Document) upon or with respect to any of
its properties, and (iv) do not and will not result in any suspension,
revocation, impairment, forfeiture or nonrenewal of any permit, license,
authorization or approval applicable to its operations or any of its properties.

                      (c) GOVERNMENTAL APPROVALS. No authorization or approval
or other action by, and no notice to or filing with, any Governmental Authority
is required in connection with the due execution, delivery and performance by
the Parent or any of its Subsidiaries of any Loan Document to which it is or
will be a party, other than such as shall have been obtained or made on or prior
to the Effective Date and other than any filings with the SEC for the purpose of
disclosing the existence of this Agreement, to the extent required under the
Securities Exchange Act of 1934, as amended, or any filings required in
connection with the actions required under Section 6.01(r).

                      (d) ENFORCEABILITY OF LOAN DOCUMENTS. This Agreement is,
and each other Loan Document to which the Parent or any of its Subsidiaries is
or will be a party, when delivered hereunder, will be, a legal, valid and
binding obligation of such Person, enforceable

                                      -30-

<PAGE>

against such Person in accordance with its terms, except as may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or other similar
laws.

                      (e) CAPITALIZATION. On the Effective Date, the authorized
Capital Stock of the Parent and the issued and outstanding Capital Stock of the
Parent are as set forth on Schedule 5.01(e). All of the issued and outstanding
shares of Capital Stock of the Parent have been validly issued and are fully
paid and nonassessable, and the holders thereof are not entitled to any
preemptive, first refusal or other similar rights. Except as described on
Schedule 5.01(e), as of the Effective Date, other than the 2000 Stock Option
Plan, there is no plan or arrangement in existence relating to the issuance of
shares of Capital Stock of the Parent and (ii) there are no outstanding debt or
equity securities of the Parent or any of its Subsidiaries and no outstanding
obligations of the Parent or any of its Subsidiaries convertible into or
exchangeable for, or warrants, options or other rights for the purchase or
acquisition from the Parent, or other obligations of the Parent to issue,
directly or indirectly, any shares of Capital Stock of the Parent.

                      (f) SUBSIDIARIES.

                          (i) Schedule 5.01(f)(i) is a complete and correct
description of the name, jurisdiction of incorporation and ownership of the
outstanding Capital Stock of each Subsidiary of the Parent in existence on the
date hereof. All of the issued and outstanding shares of Capital Stock of such
Subsidiaries have been validly issued and are fully paid and nonassessable, and
the holders thereof are not entitled to any preemptive, first refusal or other
similar rights. Except as indicated on such Schedule, all such Capital Stock is
owned by the Parent or one or more of its wholly-owned Subsidiaries, free and
clear of all Liens (other than in favor of the Lender). There are no outstanding
debt or equity securities of the Parent or any of its Subsidiaries and no
outstanding obligations of the Parent or any of its Subsidiaries convertible
into or exchangeable for, or warrants, options or other rights for the purchase
or acquisition from the Parent or any of its Subsidiaries, or other obligations
of any Subsidiary to issue, directly or indirectly, any shares of Capital Stock
of any Subsidiary of the Parent.

                          (ii) Other than the Borrower and the other
Subsidiaries of the Parent named on Schedule 5.01(f)(ii), none of the
Subsidiaries of the Parent owns any material assets or conducts any business.

                      (g) LITIGATION. Except as set forth in Schedule 5.01(g),
there is no pending or, to the knowledge of the Loan Parties, threatened action,
suit or proceeding affecting the Parent or any of its Subsidiaries before any
court or other Governmental Authority or any arbitrator that (i) if adversely
determined, could have a Material Adverse Effect or (ii) relates to this
Agreement, the Note or any other Loan Document or any transaction contemplated
hereby or thereby.

                      (h) FINANCIAL CONDITION.

                          (i) The Financial Statements, copies of which have
been delivered to the Lender, fairly present the consolidated financial
condition of the Parent and its Subsidiaries as at the respective dates thereof
and the consolidated results of operations of the Parent and its Subsidiaries
for the fiscal periods ended on such respective dates, all in accordance

                                      -31-

<PAGE>

with GAAP, and since July 31, 2000 no event or development has occurred that has
had or could have a Material Adverse Effect.

                          (ii) The Parent has heretofore furnished to the Lender
(A) projected monthly income statements, and quarterly balance sheets and
statements of cash flows of the Parent and its Subsidiaries for the period from
August 1, 2000, through January 31, 2001, and (B) projected annual balance
sheets, income statements and statements of cash flows of the Parent and its
Subsidiaries for the Fiscal Year ending January 31, 2002. Such projections, were
believed by the Parent at the time furnished to be reasonable, have been
prepared on a reasonable basis and in good faith by the Parent, and have been
based on assumptions believed by the Parent to be reasonable at the time made
and upon the best information then reasonably available to the Parent, and
except as set forth on Schedule 5.01(k), the Parent is not aware of any facts or
information that would lead it to believe that such projections, as so updated,
are incorrect or misleading in any material respect.

                      (i) COMPLIANCE WITH LAW, ETC. Subject to the effectiveness
of the Plan of Reorganization, neither the Parent nor any of its Subsidiaries is
in violation of its organizational documents, any law, rule, regulation,
judgment or order of any Governmental Authority, the Plan of Reorganization or
the Confirmation Order applicable to it or any of its property or assets, or any
material term of any agreement or instrument (including, without limitation, any
Material Contract) binding on or otherwise affecting it or any of its
properties, and no Default or Event of Default has occurred and is continuing.

                      (j) ERISA. Except as set forth on Schedule 5.01(j), (i)
each Employee Plan is in substantial compliance with ERISA and the Code, (ii) no
Termination Event has occurred nor is reasonably expected to occur with respect
to any Employee Plan, (iii) the most recent annual report (Form 5500 Series)
with respect to each Employee Plan, including any required Schedule B (Actuarial
Information) thereto, copies of which have been filed with the Internal Revenue
Service and delivered to the Lender, is complete and correct and fairly presents
the funding status of such Employee Plan, and since the date of such report
there has been no material adverse change in such funding status, (iv) no
Employee Plan had an accumulated or waived funding deficiency or permitted
decreases which would create a deficiency in its funding standard account or has
applied for an extension of any amortization period within the meaning of
Section 412 of the Code at any time during the previous 60 months and (v) no
Lien imposed under the Code or ERISA exists or is likely to arise on account of
any Employee Plan within the meaning of Section 412 of the Code at any time
during the previous 60 months. Except as set forth on Schedule 5.01(j), none of
the Parent or any of its ERISA Affiliates have incurred any withdrawal liability
under ERISA with respect to any Multiemployer Plan, or are aware of any facts
indicating that the Parent or any of its ERISA Affiliates may in the future
incur any such withdrawal liability. Except as required by Section 4980B of the
Code, none of the Parent or any of its ERISA Affiliates maintains an employee
welfare benefit plan (as defined in Section 3(1) of ERISA) which provides health
or welfare benefits (through the purchase of insurance or otherwise) for any
retired or former employee of the Parent or any of its ERISA Affiliates or
coverage after a participant's termination of employment. None of the Parent or
any of its ERISA Affiliates has incurred any liability or obligation under the
Worker Adjustment and Retraining Notification Act ("WARN") or similar state law,
which remains unpaid or unsatisfied.

                                      -32-
<PAGE>

                      (k) TAXES, ETC. Except as set forth on Schedule 5.01(k),
all Federal, state and local tax returns and other reports required by
applicable law to be filed by the Parent and each of its Subsidiaries have been
filed, or extensions have been obtained, and all taxes, assessments and other
governmental charges imposed upon the Parent or any of its Subsidiaries or any
property of the Parent or any of its Subsidiaries and which have become due and
payable on or prior to the date hereof have been paid, except to the extent
contested in good faith by proper proceedings which stay the imposition of any
penalty, fine or Lien resulting from the non-payment thereof and with respect to
which adequate reserves have been set aside for the payment thereof.

                      (l) REGULATIONS T, U AND X. Neither the Parent nor any of
its Subsidiaries is nor will be engaged in the business of extending credit for
the purpose of purchasing or carrying margin stock (within the meaning of
Regulations T, U or X), and no proceeds of any Loan will be used to purchase or
carry any margin stock or to extend credit to others for the purpose of
purchasing or carrying any margin stock.

                      (m) NATURE OF BUSINESS. Neither the Parent nor any of its
Subsidiaries is engaged in any business other than providing clinical and
support services for the pharmaceutical and managed care industries.

                      (n) ADVERSE AGREEMENTS, ETC. Neither the Parent nor any of
its Subsidiaries is a party to any agreement or instrument, or subject to any
charter, limited liability company agreement, partnership agreement or other
corporate, partnership or limited liability company restriction or any judgment,
order, regulation, ruling or other requirement of a court or other Governmental
Authority, which has, or in the future could have, a Material Adverse Effect.

                      (o) PERMITS, ETC. Each of the Parent and its Subsidiaries
has, and is in substantial compliance with, all permits, licenses,
authorizations, approvals, entitlements and accreditations required for such
Person lawfully to own, lease, manage or operate, or to acquire, each business
currently owned, leased, managed or operated, or to be acquired, by such Person.
No condition exists or event has occurred which, in itself or with the giving of
notice or lapse of time or both, would result in the suspension, revocation,
impairment, forfeiture or non-renewal of any such permit, license,
authorization, approval, entitlement or accreditation, and there is no claim
that any thereof is not in full force and effect, except as could not,
individually or in the aggregate, have a Material Adverse Effect.

                      (p) PROPERTIES.

                          (i) Each of the Parent and its Subsidiaries has good
and marketable title to, or valid leasehold interests in, all property and
assets material to its business, free and clear of all Liens except Permitted
Liens. The properties are in good working order and condition, ordinary wear and
tear excepted.

                          (ii) Schedule 5.01(p) sets forth a complete and
accurate list as of the Effective Date of the location, by state and street
address, of all real property owned or leased by any of the Parent and its
Subsidiaries. As of the Effective Date, each of the Borrower and its
Subsidiaries has valid leasehold interests in the Leases described on Schedule
5.01(p) to which it is a party. Schedule 5.01(p) sets forth with respect to each
such Lease, the commencement date,

                                      -33-
<PAGE>

termination date, renewal options (if any) and annual base rents. Each such
Lease is valid and enforceable in accordance with its terms in all material
respects and is in full force and effect. No consent or approval of any landlord
or other third party in connection with any such Lease is necessary for the
Parent or any of its Subsidiaries to enter into and execute the Loan Documents
to which it is a party, except as set forth on Schedule 5.01(p). To the
knowledge of the Loan Parties, no other party to any such Lease is in default of
its obligations thereunder, and none of the Parent and its Subsidiaries (or any
other party to any such Lease) has not at any time delivered or received any
notice of default which remains uncured under any such Lease and, subject to the
Plan of Reorganization becoming effective, as of the Effective Date, no event
has occurred which, with the giving of notice or the passage of time or both,
would constitute a default under any such Lease.

                      (q) FULL DISCLOSURE. The Loan Parties have disclosed to
the Lender all agreements, instruments and corporate or other restrictions to
which the Parent or any of its Subsidiaries is subject, and all other matters
known to it, that, individually or in the aggregate, could result in a Material
Adverse Effect. None of the other reports, financial statements, certificates or
other information furnished by or on behalf of the Loan Parties to the Lender in
connection with the negotiation of this Agreement or delivered hereunder (as
modified or supplemented by other information so furnished) contains any
material misstatement of fact or omits to state any material fact necessary to
make the statements therein, in the light of the circumstances under which it
was made, not misleading; PROVIDED that, with respect to projected financial
information, the Parent represents only that such information was prepared in
good faith based upon assumptions believed to be reasonable at the time. There
is no contingent liability or fact known to any of the Loan Parties that may
have a Material Adverse Effect which has not been set forth in a footnote
included in the Financial Statements or a schedule hereto.

                      (r) SECURITY INTERESTS. The Security Documents create in
favor of the Lender, a legal, valid and enforceable security interest in and
Lien upon the Collateral. Upon the filing of the UCC-1 financing statements
described in Section 4.01(d)(vi), the delivery to the Lender of the Pledged
Collateral (as defined in the Pledge Agreement) and the filing of the UCC-3
termination statements described in Section 4.01(xx), such security interests in
and Liens on the Collateral granted thereby shall be perfected, first priority
security interests, and no further recordings or filings are or will be required
in connection with the creation, perfection or enforcement of such security
interests and Liens, other than (i) the filing of continuation statements in
accordance with applicable law, (ii) the recording of any Assignment For
Security (Patents) and Assignment For Security (Trademarks) pursuant to the
Security Agreement in the United States Patent and Trademark Office, with
respect to after-acquired U.S. applications and registrations for patents and

the recordation of appropriate evidence of the security interest in the United
States Copyright Office.

                      (s) OPERATING LEASE OBLIGATIONS. On the Effective Date,
neither the Parent nor any of its Subsidiaries has any obligations as lessee for
the payment of rent for any real or personal property other than the Operating
Lease Obligations set forth on Schedule 5.01(s).

                      (t) ENVIRONMENTAL MATTERS. Except as set forth on Schedule
5.01(t), (i) the operations of each of the Parent and its Subsidiaries are in
compliance with Environmental Laws; (ii) there has been no Release at any of the
properties owned or operated by the Parent or its

                                      -34-
<PAGE>

Subsidiaries or a predecessor in interest, or at any disposal or treatment
facility which received Hazardous Materials generated by the Parent or its
Subsidiaries or any predecessor in interest which could have a Material Adverse
Effect; (iii) no Environmental Action has been asserted against the Parent or
its Subsidiaries or any predecessor in interest nor does the Parent or any of
its Subsidiaries have knowledge or notice of any threatened or pending
Environmental Action against the Parent or its Subsidiaries or any predecessor
in interest which could have a Material Adverse Effect; and (iv) no
Environmental Actions have been asserted against any facilities that may have
received Hazardous Materials generated by the Parent or its Subsidiaries or any
predecessor in interest which could have a Material Adverse Effect.

                      (u) INSURANCE. Each of the Parent and its Subsidiaries

may be required by law or as may be reasonably required by the Lender
(including, without limitation, against larceny, embezzlement or other criminal
misappropriation). Schedule 5.01(u) sets forth a list of all insurance
maintained by the Parent and its Subsidiaries on the Effective Date.

                      (v) USE OF PROCEEDS. The proceeds of the Loans shall be
used to (i) pay the obligations of the Loan Parties under the Plan of
Reorganization, (ii) pay costs and expenses relating to the transactions
contemplated hereby, and (iii) fund the ongoing working capital requirements of
the Parent, the Borrower and the other Permitted Subsidiaries of the Parent.

contemplated by this Agreement and before and after giving effect to each Loan,

remain, duly qualified and in good standing in each jurisdiction in which the
character of the properties owned or leased by it or in which the transaction of
its business makes such qualification necessary, except where the failure to so
qualify could not (in the Lender's reasonable judgment) reasonably be expected
to have a Material Adverse Effect.

                      (j) ENVIRONMENTAL. (i) Keep any property either owned or
operated by it or any of its Subsidiaries free of any Environmental Liens; (ii)
comply, and cause it Subsidiaries to comply, in all material respects with

Material Adverse Effect.

                      (q) CERTAIN AGREEMENTS. Agree to any amendment or other
change to or waiver of any of its rights under any Material Contract without the
prior written consent of the Lender, except where such amendment, change or
waiver could not reasonably be expected to have a Material Adverse Effect.

                      MANAGEMENT, COLLECTION AND STATUS OF
                    ACCOUNTS RECEIVABLE AND OTHER COLLATERAL

                  SECTION 7.01. COLLECTION OF ACCOUNTS RECEIVABLE; MANAGEMENT OF
COLLATERAL.

                      (a) After the occurrence and during the continuance of an
Event of Default, the Lender may send a notice of assignment and/or notice of
the Lender's security interest to any and all Account Debtors or third parties
holding or otherwise concerned with any of the Collateral, and thereafter the
Lender shall have the sole right to collect the Accounts Receivable and/or take
possession of the Collateral and the books and records relating thereto. Neither
the Parent nor the Borrower shall, and neither such Person shall permit its
Subsidiaries to, without prior written consent of the Lender, grant any
extension of time of payment of any Account Receivable, compromise or settle any
Account Receivable for less than the full amount thereof, release, in whole or
in part, any Person or property liable for the payment thereof, or allow any
credit or discount whatsoever thereon, except, in the absence of a continuing
Event of Default, as permitted by Section 6.02(o).

                      (b) Each Loan Party hereby appoints the Lender or its
designee on behalf of the Lender as such Loan Party's attorney-in-fact with
power exercisable during the continuance of any Event of Default to endorse such
Loan Party's name upon any notes, acceptances, checks, drafts, money orders or
other evidences of payment relating to the Accounts Receivable, to sign such
Loan Party's name on any invoice or bill of lading relating to any of the
Accounts Receivable, drafts against Account Debtors with respect to Accounts
Receivable, assignments and verifications of Accounts Receivable and notices to
Account Debtors with respect to Accounts Receivable, to send verification of
Accounts Receivable, and, to notify the Postal Service authorities to change the
address for delivery of mail addressed to such Loan Party or any of its
Subsidiaries to such address as the Lender may designate and to do all other
acts and things necessary to carry out this Agreement. All acts of said attorney
or designee are hereby ratified and approved, and said attorney or designate
shall not be liable for any acts of omission or commission (other than acts or
omissions constituting gross negligence or willful

                                      -53-

<PAGE>

misconduct), or for any error of judgment or mistake of fact or law; this power
being coupled with an interest is irrevocable until all of the Loans and other
Obligations under the Loan Documents are paid in full and all of the Loan
Documents are terminated.

                      (c) Nothing herein contained shall be construed to
constitute the Lender as agent of the Parent or any Subsidiary for any purpose
whatsoever, and the Lender shall not be responsible or liable for any shortage,
discrepancy, damage, loss or destruction of any part of the Collateral wherever
the same may be located and regardless of the cause thereof (other than from
acts or omissions of the Lender constituting gross negligence or willful
misconduct as determined by a final judgment of a court of competent
jurisdiction). The Lender shall not, under any circumstance or in any event
whatsoever, have any liability for any error or omission or delay of any kind
occurring in the settlement, collection or payment of any of the Accounts
Receivable or any instrument received in payment thereof or for any damage
resulting therefrom (other than acts or omissions of the Lender constituting
gross negligence or willful misconduct as determined by a final judgment of a
court of competent jurisdiction). The Lender, by anything herein or in any
assignment or otherwise, does not assume any of the obligations under any
contract or agreement assigned to the Lender and shall not be responsible in any
way for the performance by the Parent or any Subsidiary of any of the terms and
conditions thereof.

                      (d) If any Account Receivable includes a charge for any
tax payable to any Governmental Authority, the Lender is hereby authorized (but
in no event obligated) in its discretion to pay the amount thereof to the proper
taxing authority for the applicable Loan Party's account and to charge the
Borrower therefor. The Borrower shall notify the Lender if any Account
Receivable includes any taxes due to any such Governmental Authority and, in the
absence of such notice, the Lender shall have the right to retain the full
proceeds of such Account Receivable and shall not be liable for any taxes that
may be due by reason of the sale and delivery creating such Account Receivable.

                  SECTION 7.02. ACCOUNTS RECEIVABLE DOCUMENTATION. Each Loan
Party will, and will cause its Subsidiaries to, at such intervals as the Lender
may require, execute and deliver confirmatory written assignments of the
Accounts Receivable to the Lender and furnish such further schedules and/or
information as the Lender may require relating to the Accounts Receivable. In
addition, the Borrower shall notify the Lender of any non-compliance in respect
of the representations, warranties and covenants contained in Section 7.03. The
items to be provided under this Section 7.02 are to be in form reasonably
satisfactory to the Lender and are to be executed and delivered to the Lender
from time to time solely for its convenience in maintaining records of the
Collateral. A Loan Party's failure to give any of such items to the Lender shall
not affect, terminate, modify or otherwise limit the Lender's Lien on the
Collateral. The Loan Parties shall not re-date any invoice or sale or make sales
on extended dating beyond that customary in the Loan Parties industry and in the
ordinary course of the Loan Parties business. In addition, the Borrower shall
not re-bill any Accounts Receivable without promptly disclosing the same to the
Lender and providing the Lender with copy of such re-billing, identifying the
same as such. If the Borrower becomes aware of anything materially detrimental
to any of the Loan Party's customers' credit, the Borrower will promptly advise
the Lender thereof.

                  SECTION 7.03. STATUS OF ACCOUNTS RECEIVABLE AND OTHER
COLLATERAL. With respect to Collateral of any Loan Party at the time the
Collateral becomes subject to the Lender's Lien, each Loan Party covenants,
represents and warrants: (a) the Loan Party that owns such Collateral shall be
the sole owner, free and clear of all Liens except in the favor of the Lender or
otherwise permitted hereunder, and fully authorized to sell, transfer, pledge
and/or grant a security interest in each and every item of said Collateral; (b)
each Account Receivable shall be a good and valid account representing an
undisputed bona fide indebtedness incurred or an amount indisputably owed by the
Account Debtor therein named, for a fixed sum as set forth in the invoice
relating thereto with respect to any absolute sale and delivery upon the
specified terms of goods sold or services rendered by the Borrower or any Loan
Party; (c) no Account Receivable shall be subject to any defense, offset,
counterclaim, discount or allowance except as may be stated in the invoice
relating thereto, discounts and allowances as may be customary in the Loan
Parties' business and as otherwise disclosed to the Lender, and each Account
Receivable will be paid when due; (d) none of the transactions underlying or
giving rise to any Account Receivable shall violate any applicable state or
federal laws or regulations, and all documents relating thereto shall be legally
sufficient under such laws or regulations and shall be legally enforceable in
accordance with their terms; (e) no agreement under which any deduction or
offset of any kind, other than normal trade discounts, may be granted or shall
have been made by the Borrower or any Loan Party at or before the time such
Accounts Receivable is created; (f) all agreements, instruments and other
documents relating to any Account Receivable shall be true and correct and in
all material respects what they purport to be; (g) all signatures and
endorsements that appear on all material agreements, instruments and other
documents relating to Account Receivable shall be genuine and all signatories
and endorsers shall have full capacity to contract; (h) the Borrower and each
Loan Party shall maintain books and records pertaining to said Collateral in
such detail, form and scope as the Lender shall reasonably require; (i) the
Borrower shall immediately notify the Lender if any accounts arise out of
contracts with the United States or any department, agency, or instrumentality
thereof, and will, and will cause its Subsidiaries to, execute any instruments
and take any steps required by the Lender in order that all monies due or to
become due under any such contract shall be assigned to the Lender and notice
thereof given to the United States Government under the Federal Assignment of
Claims Act; (j) the Borrower will, immediately upon learning thereof, report to
the Lender any material loss or destruction of, or substantial damage to, any of
the Collateral, and any other matters affecting the value, enforceability or
collectibility of any of the Collateral; (k) if any amount payable under or in
connection with any Account Receivable is evidenced by a promissory note or
other instrument, such promissory note or instrument shall be immediately
pledged, endorsed, assigned and delivered to the Lender as additional
Collateral; (l) the Loan Parties shall not re-date any invoice or sale or make
sales on extended dating beyond that which is customary in the ordinary course
of its business and in the industry; and (m) the Loan Parties are not and shall
not be entitled to pledge the Lender's credit on any purchases or for any
purpose whatsoever.

                  SECTION 7.04. COLLATERAL CUSTODIAN. Upon the occurrence and
during the continuance of any Event of Default, the Lender may at any time and
from time to time employ and maintain on the premises of the Loan Parties a
custodian selected by the Lender who shall have full authority to do all acts
necessary to protect the Lender's interests. Each of the Parent and the Borrower
hereby agrees to, and to cause its Subsidiaries to, cooperate with any such
custodian and to do whatever the Lender may reasonably request to preserve the
Collateral. All

                                      -55-

<PAGE>

reasonable costs and expenses incurred by the Lender by reason of the employment
of the custodian shall be the responsibility of the Borrower and charged to the
Loan Account.

                      (s) an injunction against the conducting of business is
imposed by a court or other Governmental Authority against the Borrower or any
Loan Party for more than

fifteen (15) consecutive days, if such event could reasonably be expected to
have a Material Adverse Effect;

then, and in any such event, the Lender may, by notice to the Parent or the
Borrower, (i) terminate the Commitment, whereupon the Commitment shall terminate
immediately, (ii) declare all Loans then outstanding to be due and payable,
whereupon the aggregate principal of such Loans, all accrued and unpaid interest
thereon, all fees and all other amounts payable under this Agreement shall
become due and payable immediately, without presentment, demand, protest or
further notice of any kind, all of which are hereby expressly waived by the Loan
Parties and (iii) exercise any and all of its other rights and remedies under
applicable law, hereunder and under the other Loan Documents; PROVIDED, HOWEVER,
that upon the occurrence of any Event of Default with respect to a Loan Party
described in subsection (f) or (g) of this Section 8.01, without any notice to
the Parent, the Borrower or any other Person or any act by the Lender, the
Commitment shall automatically terminate and the Loans then outstanding,
together with all accrued and unpaid interest thereon, all fees and all other
amounts due under this Agreement shall become due and payable automatically and
immediately, without presentment, demand, protest or notice of any kind, all of
which are expressly waived by the Loan Parties.


                                   ARTICLE IX

                                    GUARANTY

                  SECTION 9.01. GUARANTY; LIMITATION OF LIABILITY. The
Guarantors, jointly and severally, hereby unconditionally and irrevocably
guarantees the punctual payment when due, whether at stated maturity, by
acceleration or otherwise, of all obligations of the Borrower now or hereafter
existing under any Loan Document, whether for principal, interest, fees,
expenses or otherwise (such obligations, to the extent not paid by the Borrower,
being the "GUARANTEED OBLIGATIONS"), and agrees to pay any and all expenses
(including reasonable counsel fees and expenses) incurred by the Lender in
enforcing any rights under the guaranty set forth in this Article. Without
limiting the generality of the foregoing, each Guarantor's liability shall
extend to all amounts that constitute part of the Guaranteed Obligations and
would be owed by the Borrower to the Lender under any Loan Document but for the
fact that they are unenforceable or not allowable due to the existence of a
bankruptcy, reorganization or similar proceeding involving the Borrower or
another Loan Party.

                  SECTION 9.02. GUARANTY ABSOLUTE. The Guarantors jointly and
severally guarantee that the Guaranteed Obligations will be paid strictly in
accordance with the terms of the Loan Documents, regardless of any law,
regulation or order now or hereafter in effect in any jurisdiction affecting any
of such terms or the rights of the Lender with respect thereto. The obligations
of the Guarantors under this Article are independent of the Guaranteed
Obligations, and a separate action or actions may be brought and prosecuted
against one or more of the Guarantors to enforce such obligations, irrespective
of whether any action is brought against the Borrower or whether the Borrower is
joined in any such action or actions. The joint and several liability of the
Guarantors under this Article shall be irrevocable, absolute and unconditional
irrespective of, and each Guarantor hereby irrevocably waives any defenses it
may now or hereafter have in any way relating to, any or all of the following:

                                      -59-

<PAGE>

                      (a) any lack of validity or enforceability of any Loan
Document or any agreement or instrument relating thereto;

                      (b) any change in the time, manner or place of payment of,
or in any other term of, all or any of the Guaranteed Obligations, or any other
amendment or waiver of or any consent to departure from any Loan Document,
including, without limitation, any increase in the Guaranteed Obligations
resulting from the extension of additional credit to the Borrower or otherwise;

                      (c) any taking, exchange, release or non-perfection of any
Collateral, or any taking, release or amendment or waiver of or consent to
departure from any other guaranty, for all or any of the Guaranteed Obligations;

                      (d) any change, restructuring or termination of the
corporate, limited liability company or partnership structure or existence of
the Borrower; or

                      (e) any other circumstance (including, without limitation,
any statute of limitations) or any existence of or reliance on any
representation by the Lender that might otherwise constitute a defense available
to, or a discharge of, any Guarantor, the Borrower or any other guarantor or
surety.

This Article shall continue to be effective or be reinstated, as the case may
be, if at any time any payment of any of the Guaranteed Obligations is rescinded
or must otherwise be returned by the Lender or any other Person upon the
insolvency, bankruptcy or reorganization of the Borrower, any Guarantor or
otherwise, all as though such payment had not been made.

                  SECTION 9.03. WAIVER. Each Guarantor hereby waives promptness,
diligence, notice of acceptance and any other notice with respect to any of the
Guaranteed Obligations and this Article and any requirement that the Lender
exhaust any right or take any action against the Borrower or any other Person or
any collateral. Each Guarantor acknowledges that it will receive direct and
indirect benefits from the financing arrangements contemplated herein and that
the waiver set forth in this Section 9.03 is knowingly made in contemplation of
such benefits. Each Guarantor hereby waives any right to revoke this Article,
and acknowledges that this Article is continuing in nature and applies to all
Guaranteed Obligations, whether existing now or in the future.

                  SECTION 9.04. CONTINUING GUARANTY; ASSIGNMENTS. This Article
is a continuing guaranty and shall (a) remain in full force and effect until the
later of the cash payment in full of the Guaranteed Obligations (other than
indemnification obligations as to which no claim has been made) and all other
amounts payable under this Article and the Final Maturity Date, (b) be binding
upon each Guarantor, its successors and assigns and (c) inure to the benefit of
and be enforceable by the Lender and its successors, pledgees, transferees and
assigns. Without limiting the generality of the foregoing clause (c), the Lender
may pledge, assign or otherwise transfer all or any portion of its rights and
obligations under this Agreement (including, without limitation, all or any
portion of its Commitment, the Loans owing to it and the Note held by it) to any
other Person, and such other Person shall thereupon become vested

                                      -60-
<PAGE>

with all the benefits in respect thereof granted the Lender herein or otherwise,
in each case as provided in Section 10.07.


                  SECTION 9.05. SUBROGATION. Each Guarantor agrees that it will
not exercise any rights that it may now or hereafter acquire against the
Borrower or any other Guarantor that arise from the existence, payment,
performance or enforcement of such Guarantor's obligations under this Article,
including, without limitation, any right of subrogation, reimbursement,
exoneration, contribution or indemnification and any right to participate in any
claim or remedy of the Lender against the Borrower or any other Guarantor or any
collateral, whether or not such claim, remedy or right arises in equity or under
contract, statute or common law, including, without limitation, the right to
take or receive from the Borrower or any other Guarantor, directly or
indirectly, in cash or other property or by set-off or in any other manner,
payment or security solely on account of such claim, remedy or right, unless and
until all of the Guaranteed Obligations and all other amounts payable under this
Article shall have been paid in full in cash and the Final Maturity Date shall
have occurred. If any amount shall be paid to Guarantor in violation of the
immediately preceding sentence at any time prior to the later of the payment in
full in cash of the Guaranteed Obligations and all other amounts payable under
this Article and the Final Maturity Date, such amount shall be held in trust for
the benefit of the Lender and shall forthwith be paid to the Lender to be
credited and applied to the Guaranteed Obligations and all other amounts payable
under this Article, whether matured or unmatured, in accordance with the terms
of this Agreement, or to be held as collateral for any Guaranteed Obligations or
other amounts payable under this Article thereafter arising. If (i) any
Guarantor shall make payment to the Lender of all or any part of the Guaranteed
Obligations, (ii) all of the Guaranteed Obligations and all other amounts
payable under this Article shall be paid in full in cash and (iii) the Final
Maturity Date shall have occurred, the Lender will, at such Guarantor's request
and expense, execute and deliver to such Guarantor appropriate documents,
without recourse and without representation or warranty, necessary to evidence
the transfer by subrogation to such Guarantor of an interest in the Guaranteed
Obligations resulting from such payment by such Guarantor.

<PAGE>

                  SECTION 10.03. NO WAIVER; REMEDIES, ETC. No failure on the
part of the Lender to exercise, and no delay in exercising, any right hereunder
or under any other Loan Document shall operate as a waiver thereof; nor shall
any single or partial exercise of any right under any Loan Document preclude any
other or further exercise thereof or the exercise of any other right. The rights
and remedies of the Lender provided herein and in the other Loan Documents are
cumulative and are in addition to, and not exclusive of, any rights or remedies
provided by law. The rights of the Lender under any Loan Document against any
party thereto are not conditional or contingent on any attempt by the Lender to
exercise any of their rights under any other Loan Document against such party or
against any other Person.

                  SECTION 10.04. EXPENSES; TAXES; ATTORNEYS' FEES. The Borrower
will pay on demand, all costs and expenses incurred by or on behalf of the
Lender, regardless of whether the transactions contemplated hereby are
consummated, including, without limitation, reasonable fees, costs, client
charges and expenses of counsel for the Lender, accounting, due diligence,
periodic field audits, physical counts, valuations, fees of Rating Agencies
associated with the rating of the Loans, investigations, monitoring of assets,
appraisals of Collateral, environmental assessments, miscellaneous
disbursements, examination, travel, lodging and meals, arising from or relating
to: (a) the negotiation, preparation, execution, delivery, performance and
administration of this Agreement and the other Loan Documents, (including,
without limitation, the preparation of any additional Loan Documents pursuant to
Section 6.01(b)), (b) any requested amendments, waivers or consents to this
Agreement or the other Loan Documents whether or not such documents become
effective or are given, (c) the preservation and protection of any of the
Lender's rights under this Agreement or the other Loan Documents, (d) the
defense of any claim or action asserted or brought against the Lender by any
Person that arises from or relates to this Agreement, any other Loan Document,
the Lender's claims against the Borrower and each other Loan Party, or any and
all matters in connection therewith, (e) the commencement or defense of, or
intervention in, any court proceeding arising from or related to this Agreement
or any other Loan Document, (f) the filing of any petition, complaint, answer,
motion or other pleading by the Lender, or the taking of any action in respect
of the Collateral or other security, in connection with this Agreement or any

or in connection with the past, present or future operations of any Loan Party
involving any damage to real or personal property or natural resources or harm
or injury alleged to have resulted from any Release of Hazardous Materials on,
upon or into such property, (l) any Environmental Liabilities and Costs incurred
in connection with the investigation, removal, cleanup and/or remediation of any
Hazardous Materials present or arising out of the operations of any facility of
any Loan Party, or (m) any Environmental Liabilities and Costs incurred in
connection with any Environmental Lien. Without limitation of the foregoing or
any other provision of any Loan Document: (x) the Borrower agrees to pay all
stamp, document, transfer, recording or filing taxes or fees and similar
impositions now or hereafter determined by the Lender to be payable in
connection with this Agreement or any other Loan Document, and the Borrower
agrees to save the Lender harmless from and against any and all present or
future claims, liabilities or losses with respect to or resulting from any
omission

                                      -63-
<PAGE>

to pay or delay in paying any such taxes, fees or impositions, (y) the Borrower
agrees to pay all broker fees that may become due in connection with the
transactions contemplated by this Agreement, and (z) if the Borrower fails to
perform any covenant or agreement contained herein or in any other Loan
Document, the Lender may itself perform or cause performance of such covenant or
agreement, and the expenses of the Lender incurred in connection therewith shall
be reimbursed on demand by the Borrower.

                  SECTION 10.05. RIGHT OF SET-OFF. Upon the occurrence and
during the continuance of any Event of Default, the Lender may, and is hereby
authorized to, at any time and from time to time, without notice to the Loan
Parties (any such notice being expressly waived by the Loan Parties) and to the
fullest extent permitted by law, 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 to or for the credit or the account
of any Loan Party against any and all obligations of either now or hereafter
existing under any Loan Document, irrespective of whether or not the Lender
shall have made any demand hereunder or thereunder and although such obligations
may be contingent or unmatured. The Lender agrees to notify the Parent or the
Borrower promptly after any such set-off and application made by the Lender
provided that the failure to give such notice shall not affect the validity of
such set-off and application.

                  SECTION 10.06. 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 portions hereof or affecting
the validity or enforceability of such provision in any other jurisdiction.

                  SECTION 10.07.   ASSIGNMENTS AND PARTICIPATIONS.

                      (a) This Agreement and the Note shall be binding upon and
inure to the benefit of the Loan Parties and the Lender and their respective
successors and assigns; PROVIDED, however, that (i) none of the Loan Parties may
assign or transfer any of such Person's rights hereunder, or under the Note,
without the prior written consent of the Lender and any such assignment without
the Lender's prior written consent shall be null and void, and (ii) the Lender
may pledge, assign, sell or transfer any of its rights hereunder, or under the
Note, to (A) any affiliated investment vehicle controlled by or under common
control with the Lender upon notice to, but without the prior written consent
of, any Loan Party, (B) to any Person upon the occurrence and during the
continuance of an Event of Default or as collateral security for any obligations
of the Lender to such Person, in either case upon notice to, but without the
written consent of, any Loan Party, or (C) to any other Person with the prior
written consent of the Parent or the Borrower, such consent not to be
unreasonably withheld or delayed. Except as provided in this Section 10.07, this
Agreement shall not inure to the benefit of any party other than the Borrower,
the other Loan Parties and the Lender.

                      (b) The Lender may participate to an Affiliate of the
Lender or any other Person its rights and obligations under this Agreement
(including, without limitation, all or a portion of its Commitment, the Loans
made by it, and the Note held by it) without notice to or the consent of the
Loan Parties. In connection with any such participation or in connection with
any transfer described in clause (ii) of Section 10.07(a), the Borrower shall
execute and deliver a new Note or Notes, and the Borrower and the other Loan
Parties shall execute and deliver any

                                      -64-
<PAGE>

amendment or other modification restatement of this Agreement or any Loan
Document, as may be reasonably requested by the Lender to reflect any such
transfer.

                          (i) the Borrower shall maintain, or cause to be
maintained, a register (the "REGISTER") on which it enters the name of the
Lender as the registered owner of the Loan held by the Lender. A Registered Loan
(and the Registered Note, if any, evidencing the same) may be assigned or sold
in whole or in part only by registration of such assignment or sale on the
Register (and each Registered Note shall expressly so provide). Any assignment
or sale of all or part of such Registered Loan (and the Registered Note, if any,
evidencing the ]same) may be effected only by registration of such assignment or
sale on the Register, together with the surrender of the Registered Note, if
any, evidencing the same duly endorsed by (or accompanied by a written
instrument of assignment or sale duly executed by) the holder of such Registered
Note, whereupon, at the request of the designated assignee(s) or transferee(s),
one or more new Registered Notes in the same aggregate principal amount shall be
issued to the designated assignee(s) or transferee(s). Prior to the registration
of assignment or sale of any Registered Loan (and the Registered Note, if any
evidencing the same), the Borrower shall treat the Person in whose name such
Loan (and the Registered Note, if any, evidencing the same) is registered as the
owner thereof for the purpose of receiving all payments thereon and for all
other purposes, notwithstanding notice to the contrary.

                          (ii) In the event that the Lender sells participations
in the Registered Loan, the Lender shall maintain a register on which it enters
the name of all participants in the Registered Loans held by it (the
"PARTICIPANT REGISTER"). A Registered Loan (and the Registered Note, if any,
evidencing the same) may be participated in whole or in part only by
registration of such participation on the Participant Register (and each
Registered Note shall expressly so provide). Any participation of such
Registered Loan (and the Registered Note, if any, evidencing the same) may be
effected only by the registration of such participation on the Participant
Register.

                          (iii) Any foreign Person who purchases or is assigned
or participates in any portion of such Loan shall provide the Borrower (in the
case of a purchase or assignment) or the Lender (in the case of a participation)
with a completed Internal Revenue Service Form W-8 (Certificate of Foreign
Status) or a substantially similar form for such purchaser, participant or any
other affiliate who is a holder of beneficial interests in the Loan.

                  SECTION 10.08. COUNTERPARTS. This Agreement may be executed in
any number of counterparts and by different parties hereto in separate
counterparts, each of which shall be deemed to be an original, but all of which
taken together shall constitute one and the same agreement.

                  SECTION 10.09. GOVERNING LAW. THIS AGREEMENT, THE NOTE AND THE
OTHER LOAN DOCUMENTS SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAW OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED IN
THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES.

                  SECTION 10.10. CONSENT TO JURISDICTION; SERVICE OF PROCESS AND
VENUE. ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY
OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK IN THE
COUNTY OF NEW YORK OR OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN
DISTRICT OF NEW YORK, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH
LOAN PARTY HEREBY IRREVOCABLY ACCEPTS IN RESPECT OF ITS PROPERTY, GENERALLY AND
UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS. EACH LOAN PARTY
FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THE
AFOREMENTIONED COURTS AND IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF
COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO PARENT OR
BORROWER AT ITS ADDRESS FOR NOTICES AS SET FORTH IN SECTION 10.01, SUCH SERVICE
TO BECOME EFFECTIVE TEN (10) DAYS AFTER SUCH MAILING. EACH LOAN PARTY HEREBY
IRREVOCABLY APPOINTS THE SECRETARY OF STATE OF THE STATE OF NEW YORK AS ITS
AGENT FOR SERVICE OF PROCESS IN RESPECT OF ANY SUCH ACTION OR PROCEEDING.
NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE LENDER TO SERVICE OF PROCESS IN ANY
OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE
PROCEED AGAINST EACH LOAN PARTY IN ANY OTHER JURISDICTION. EACH LOAN PARTY
HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW,
ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE JURISDICTION OR LAYING
OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND
ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. TO
THE EXTENT THAT EACH LOAN PARTY HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM
JURISDICTION OF ANY COURT OR FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR
NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR
OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, EACH LOAN PARTY HEREBY
IRREVOCABLY WAIVES SUCH IMMUNITY IN RESPECT OF ITS OBLIGATIONS UNDER THIS
AGREEMENT AND THE OTHER LOAN DOCUMENTS.

                  SECTION 10.11. WAIVER OF JURY TRIAL, ETC. EACH LOAN PARTY AND
THE LENDER HEREBY WAIVE ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING
OR COUNTERCLAIM CONCERNING ANY RIGHTS UNDER THIS AGREEMENT, THE NOTE OR OTHER
LOAN DOCUMENTS, OR UNDER ANY AMENDMENT, WAIVER, CONSENT, INSTRUMENT, DOCUMENT OR
OTHER AGREEMENT DELIVERED OR WHICH IN THE FUTURE MAY BE DELIVERED IN CONNECTION
THEREWITH, OR ARISING FROM ANY FINANCING RELATIONSHIP EXISTING IN CONNECTION
WITH THIS AGREEMENT, AND AGREE THAT ANY SUCH ACTION, PROCEEDINGS OR COUNTERCLAIM
SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY. EACH LOAN PARTY CERTIFIES
THAT NO OFFICER, REPRESENTATIVE, AGENT OR ATTORNEY OF THE LENDER HAS
REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE LENDER WOULD NOT, IN THE EVENT OF
ANY ACTION, PROCEEDING OR COUNTERCLAIM, SEEK TO ENFORCE THE


                                      -66-

<PAGE>

FOREGOING WAIVERS. EACH LOAN PARTY HEREBY ACKNOWLEDGES THAT THIS PROVISION IS A
MATERIAL INDUCEMENT FOR THE LENDER ENTERING INTO THIS AGREEMENT.

                  SECTION 10.12. CONSENT BY THE LENDER. Except as otherwise
expressly set forth herein to the contrary, if the consent, approval,
satisfaction, determination, judgment, acceptance or similar action (an
"ACTION") of the Lender shall be permitted or required pursuant to any provision
hereof or any provision of any other agreement to which any Loan Party is a
party and to which the Lender has succeeded thereto, such Action shall be
required to be in writing.

                  SECTION 10.13. NO PARTY DEEMED DRAFTER. Each of the parties
hereto agrees that no party hereto shall be deemed to be the drafter of this
Agreement.

                  SECTION 10.14. REINSTATEMENT; CERTAIN PAYMENTS. If any claim
is ever made upon the Lender for repayment or recovery of any amount or amounts
received by the Lender in payment or on account of any of the Obligations, the
Lender shall give prompt notice of such claim to the Parent or the Borrower, and
if the Lender repays all or part of such amount by reason of (i) any judgment,
decree or order of any court or administrative body having jurisdiction over the
Lender or any of its property, or (ii) any good faith settlement or compromise
of any such claim effected by the Lender with any such claimant, then and in
such event the Borrower agrees that (A) any such judgment, decree, order,
settlement or compromise shall be binding upon it notwithstanding the
cancellation of the Note or other instrument evidencing the Obligations or the
other Loan Documents or the termination of this Agreement or the other Loan
Documents, and (B) it shall be and remain liable to the Lender hereunder for the
amount so repaid or recovered to the same extent as if such amount had never
originally been received by the Lender.

                  SECTION 10.15. INDEMNIFICATION. In addition to the Borrower's
other Obligations under this Agreement, the Borrower agrees to defend, protect,
indemnify and hold harmless the Lender, any Securitization Party and all of
their respective officers, directors, employees, attorneys, consultants and
agents (collectively called the "INDEMNITEES") from and against any and all
losses, damages, liabilities, obligations, penalties, fees, reasonable costs and
expenses (including, without limitation, reasonable attorneys' fees, costs and
expenses) incurred by such Indemnitees, whether prior to or from and after the
Effective Date, whether direct, indirect or consequential, as a result of or
arising from or relating to or in connection with any of the following: (i) the
negotiation, preparation, execution or performance or enforcement of this
Agreement, any other Loan Document or of any other document executed in
connection with the transactions contemplated by this Agreement, (ii) the
Lender's furnishing of funds to the Borrower under this Agreement, including,
without limitation, the management of any such Loans, (iii) any matter relating
to the financing transactions contemplated by this Agreement or the other Loan
Documents or by any document executed in connection with the transactions
contemplated by this Agreement or the other Loan Documents, or (iv) any claim,
litigation, investigation or proceeding relating to any of the foregoing,
whether or not any Indemnitee is a party thereto (collectively, the "INDEMNIFIED
MATTERS"); PROVIDED, HOWEVER, that the Borrower shall not have any obligation to
any Indemnitee under this Section 10.15 for any Indemnified Matter caused by the
gross negligence or willful misconduct of such Indemnitee, as determined by a
final judgment of a court of competent jurisdiction. Such indemnification for
all of the foregoing losses, damages, fees, costs and expenses of the
Indemnitees are chargeable against the Loan Account. To the extent that the

                                      -67-
<PAGE>

undertaking to indemnify, pay and hold harmless set forth in this Section 10.15
may be unenforceable because it is violative of any law or public policy, the
Borrower shall contribute the maximum portion which it is permitted to pay and
satisfy under applicable law, to the payment and satisfaction of all Indemnified
Matters incurred by the Indemnitees. This Indemnity shall survive the repayment
of the Obligations and the discharge of the Liens granted under the Loan
Documents.

                  SECTION 10.16. RECORDS. The unpaid principal of and interest
on the Note, the interest rate or rates applicable to such unpaid principal and
interest, the duration of such applicability, the Commitment, and the accrued
and unpaid fees payable pursuant to Section 2.06 hereof, including, without
limitation, the Commitment Fee, the Closing Fee, the Unused Line Fee, the Loan
Servicing Fee, the Field Examination Fee and the Anniversary Fee, shall at all
times be ascertained from the records of the Lender, which shall be conclusive
and binding absent manifest error.

                  SECTION 10.17. BINDING EFFECT. This Agreement shall become
effective when it shall have been executed by the Parent, the Borrower, the
other Guarantors and the Lender and when the conditions precedent set forth in
Section 4.01 hereof have been satisfied or waived in writing by the Lender, and
thereafter shall be binding upon and inure to the benefit of the Parent, the
Borrower, the other Guarantors and the Lender, and their respective successors
and assigns, except that the Parent, the Borrower and the other Guarantors shall
not have the right to assign their rights and obligations hereunder or any
interest herein without the prior written consent of the Lender, and any
assignment by the Lender shall be governed by Section 10.07 hereof.

                  SECTION 10.18. JOINT AND SEVERAL. The obligations of the Loan
Parties hereunder are joint and several. The Lender may, in its sole and
absolute discretion, enforce the provisions hereof against one or more of the
Loan Parties and shall not be required to proceed against all of the Loan
Parties jointly or seek payment from the Loan Parties ratably. In addition, the
Lender may, in its sole and absolute discretion, select the Collateral of one or
more of the Loan Parties for sale or application to the Obligations, without
regard to the ownership of such Collateral, and shall not be required to make
such selection ratably from the Collateral owned by any Loan Parties. The
release or discharge of any Loan Party by the Lender shall not release or
discharge any other Loan Party from the obligations of such Person hereunder.

                  SECTION 10.19. CONFIDENTIALITY. The Lender agrees (on behalf
of itself and each of its affiliates, directors, officers, employees and
representatives) to use reasonable precautions to keep confidential, in
accordance with its customary procedures for handling confidential information
of this nature and in accordance with safe and sound practices of comparable
commercial finance companies, any non-public information supplied to it by the
Borrower pursuant to this Agreement or the other Loan Documents which is
identified by the Borrower as being confidential at the time the same is
delivered to such Person (and which at the time is not, and does not thereafter
become, publicly available or available to such Person from another source not
known to be subject to a confidentiality obligation to such Person not to
disclose such information), PROVIDED that nothing herein shall limit the
disclosure of any such information (i) to the extent required by statute, rule,
regulation or judicial process, (ii) to counsel for the Lender, (iii) to
examiners, auditors, accountants or Securitization Parties, (iv) in connection
with any litigation to which the Lender is a party or (v) to any assignee or
participant

                                      -68-

<PAGE>

(or prospective assignee or participant) so long as such assignee or participant
(or prospective assignee or participant) first agrees to be bound by
confidentiality provisions similar in substance to this Section 10.19. The
Lender agrees that, upon receipt of a request or identification of the
requirement for disclosure pursuant to clause (iv) hereof, it will make
reasonable efforts to keep the Parent or the Borrower informed of such request
or identification; PROVIDED that the Loan Parties acknowledge that the Lender
may make disclosure as required or requested by any Governmental Authority or
representative thereof and that the Lender may be subject to review by
Securitization Parties or other regulatory agencies and may be required to
provide to, or otherwise make available for review by, the representatives of
such parties or agencies any such non-public information.
