                           LOAN AND SECURITY AGREEMENT

This Loan and Security Agreement (as it may be amended, this "Agreement") is
entered into on August 5, 1999 between NATIONSCREDIT COMMERCIAL CORPORATION,
THROUGH ITS NATIONSCREDIT COMMERCIAL FUNDING Division ("Lender"), having an
address at 1177 Avenue of the Americas, 36th Floor, New York, New York 10036 and
PRT GROUP INC., a Delaware corporation ("Borrower"), whose chief executive
office is located at 80 Lamberton Road, Windsor, Connecticut 06095 ("Borrower's
Address"). The Schedules to this Agreement are an integral part of this
Agreement and are incorporated herein by reference. Terms used, but not defined
elsewhere, in this Agreement are defined in Schedule B.

1.    LOANS AND CREDIT ACCOMMODATIONS.

1.1 Amount. Subject to the terms and conditions contained in this Agreement,
Lender will:

      (a) Revolving Loans and Credit Accommodations. From time to time during
the Term at Borrower's request, make revolving loans to Borrower ("Revolving
Loans"), and make letters of credit, bankers acceptances and other credit
accommodations ("Credit Accommodations") available to Borrower, in each case to
the extent that there is sufficient Availability at the time of such request to
cover, dollar for dollar, the requested Revolving Loan or Credit Accommodation;
provided, that after giving effect to such Revolving Loan or Credit
Accommodation, (x) the outstanding balance of all monetary Obligations
(including the principal balance of any Term Loan and, solely for the purpose of
determining compliance with this provision, the Credit Accommodation Balance)
will not exceed the Maximum Facility Amount set forth in Section l(a) of
Schedule A and (y) none of the other Loan Limits set forth in Section 1 of
Schedule A will be exceeded. For this purpose, "Availability" means:

            (i) the aggregate amount of Eligible Accounts (less maximum existing
or asserted taxes, discounts, credits and allowances) multiplied by the Accounts
Advance Rate set forth in Section 1 (b )(i) of Schedule A but not to exceed the
Accounts Sublimit set forth in Section 1 (c) of Schedule A;

                                      plus

            (ii) the lower of cost or market value of Eligible Inventory
multiplied by the Inventory Advance Rate(s) set forth in Section l(b)(ii) of
Schedule A, but not to exceed the Inventory Sublimit(s) set forth in Section
l(d) of Schedule A;

                                      minus

            (iii) all Reserves which Lender has established pursuant to Section
1.2 (including those to be established in connection with the requested
Revolving Loan or Credit Accommodation);

                                      minus

            (iv) the outstanding balance of all of the monetary Obligations
(excluding the Credit Accommodation Balance and the principal balance of the
Term Loan); and

                                      plus


                                                                               1
<PAGE>

            (v) the Overadvance Amount, if any, set forth in Section 1 (g) of
Schedule A.

      (b) Term Loan. On the date of this Agreement, the parties do not have any
intentions to enter into a Term Loan transaction. However, references to Term
Loan and related definitions have been retained in this Agreement to facilitate
documentation of a Term Loan in the event the parties agree to enter into such
at a later date. An Equipment Advance shall mean an advance to Borrower computed
with respect to the value of Borrower's Eligible Equipment (the ("Equipment
Advance") in the principal amount, if any, set forth in Section 2(a)(i) of
Schedule A, and, a Real Property Advance means an advance to Borrower computed
with respect to the value of Borrower's Eligible Real Property (the "Real
Property Advance") in the principal amount, if any, set forth in Section
2(a)(ii) of Schedule A. The Equipment Advance and the Real Property Advance are
collectively referred to as the "Term Loan."

1.2 Reserves. Lender may from time to time establish and revise such reserves as
Lender deems appropriate in its sole discretion ("Reserves") to reflect (i)
events, conditions, contingencies or risks which affect or may affect (A) the
Collateral or its value, or the security interests and other rights of Lender in
the Collateral or (B) the assets, business or prospects of Borrower or any
Obligor, (ii) Lender's good faith concern that any Collateral report or
financial information furnished by or on behalf of Borrower or any Obligor to
Lender is or may have been incomplete, inaccurate or misleading in any material
respect, (iii) any fact or circumstance which Lender determines in good faith
constitutes, or could constitute, a Default or Event of Default or (iv) any
other events or circumstances which Lender determines in good faith make the
establishment or revision of a Reserve prudent. Without limiting the foregoing,
Lender shall (x) in the case of each Credit Accommodation issued for the
purchase of Inventory (a) which meets the criteria for Eligible Inventory set
forth in clauses (i), (ii), (iii), (v) and (vi) of the definition of Eligible
Inventory, (b) which is or will be in transit to one of the locations set forth
in Section 9(d) of Schedule A, (c) which is fully insured in a manner
satisfactory to Lender and (d) with respect to which Lender is in possession of
all bills of lading and all other documentation which Lender has requested, all
in form and substance satisfactory to Lender in its sole discretion, establish a
Reserve equal to the cost of such Inventory (plus all duties, freight, taxes,
insurance, costs and other charges and expenses relating to such Credit
Accommodation or such Eligible Inventory) multiplied by a percentage equal to
100% minus the Inventory Advance Rate applicable to Eligible Inventory and (y)
in the case of any other Credit Accommodation issued for any purpose, establish
a Reserve equal to the full amount of such Credit Accommodation plus all costs
and other charges and expenses relating to such Credit Accommodation. In
addition, (x) Lender shall establish a permanent Reserve in the amount set forth
in Section 1 (f) of Schedule A, and (y) if the outstanding principal balance of
the Term Loan advance with respect to Eligible Equipment exceeds the percentage
set forth in Section 2(a)(i) of Schedule A of the appraised value of such
Eligible Equipment, Lender may establish an additional Reserve in the amount of
such excess (and, for this purpose, if payments of principal on the Term Loan
advances against Eligible Equipment and Real Property are not calculated
separately, payments of principal of the Term Loan made by Borrower shall be
deemed to apply to the Term Loan advance with respect to Eligible Equipment and
Real Property, respectively, in proportion to the original principal amounts of
such advances). Lender may, in its discretion, establish and revise Reserves by
deducting them in determining Availability or by reclassifying Eligible Accounts
or Eligible Inventory as ineligible. In no event shall the establishment of a
Reserve in respect of a particular


                                                                               2

actual or contingent liability obligates Lender to make advances hereunder to
pay such liability or otherwise obligate Lender with respect thereto.

1.3 Other Provisions Applicable to Credit Accommodations. Lender may, in its
sole discretion and on terms and conditions acceptable to Lender, make Credit
Accommodations available to Borrower either by issuing them, or by causing other
financial institutions to issue them supported by Lender's guaranty or
indemnification; provided, that after giving effect to each Credit
Accommodation, the Credit Accommodation Balance will not exceed the Credit
Accommodation Limit set forth in Section l(e) of Schedule A. Any amounts paid by
Lender in respect of a Credit Accommodation will be treated for all purposes as
a Revolving Loan which shall be secured by the Collateral and bear interest, and
be payable, in the same manner as a Revolving Loan. Borrower agrees to execute
all documentation required by Lender or the issuer of any Credit Accommodation
in connection with any such Credit Accommodation.

1.4 Repayment. Except as set forth on Schedule D, accrued interest on all
monetary Obligations shall be payable on the first day of each month. Principal
of the Term Loan shall be repaid as set forth in Section 2(b ) of Schedule A. If
at any time any of the Loan Limits are exceeded, Borrower will immediately pay
to Lender such amounts (or provide cash collateral to Lender with respect to the
Credit Accommodation Balance in the manner set forth in Section 7.3), as shall
cause Borrower to be in full compliance with all of the Loan Limits.
Notwithstanding the foregoing, Lender may, in its sole discretion, make or
permit Revolving Loans, the Term Loan, any Credit Accommodations or an y other
monetary Obligations to be in excess of any of the Loan Limits; provided, that
Borrower shall, upon Lender's demand, pay to Lender such amounts as shall cause
Borrower to be in full compliance with all of the Loan Limits. All unpaid
monetary Obligations shall be payable in full on the Maturity Date (as defined
in Section 7.1) or, if earlier, the date of any early termination pursuant to
Section 7.2.

1.5 Minimum Borrowing. Subject to the terms and conditions of this Agreement,
Borrower agrees to (i) borrow sufficient amounts to cause the outstanding
principal balance of the Loans to equal or exceed, at all times prior to the
Maturity Date, the Minimum Loan Amount set forth in Section 4 of Schedule A and
(ii) maintain Availability sufficient to enable Borrower to do so. However,
Lender shall not be obligated. to loan Borrower the Minimum Loan Amount other
than in accordance with all of the terms and conditions of this Agreement.

2.    INTEREST AND FEES.

2.1 Interest. All Loans and other monetary Obligations shall bear interest at
the Interest Rate(s) set forth in Section 3 of Schedule A, as supplemented by
Schedule D, except where expressly set forth to the contrary in this Agreement
or another Loan Document; provided, that after the occurrence of an Event of
Default, all Loans and other monetary Obligations shall, at Lender's option,
bear interest at a rate per annum equal to two percent (2%) in excess of the
rate otherwise applicable thereto (the "Default Rate") until paid in full
(notwithstanding the entry of any judgment against Borrower or the exercise of
any other right or remedy by Lender), and all such interest shall be payable on
demand. Changes in the Interest Rate shall be effective as of the date of any
change in the Prime Rate. Notwithstanding anything to the contrary contained in
this Agreement, the


                                                                               3
<PAGE>

aggregate of all amounts deemed to be interest hereunder and charged or
collected by Lender is not intended to exceed the highest rate permissible under

refund to Borrower any such excess interest received by Lender.

Lender the following warrants, which are in addition to all interest and other
sums payable by Borrower to Lender under this Agreement, and are not refundable:

      (d) Unused Line Fee. An unused line fee at a rate equal to the percentage

the first day of each month so long as any of the Obligations are outstanding
and on the Maturity Date.

      (e) Minimum Borrowing Fee. A minimum borrowing fee equal to the excess, if

earned as of the last day of such period and payable on the date set forth in
Section 6(e )(ii) of Schedule A and on the Maturity Date, commencing with the
immediately following period.


                                                                               4

2.3 Computation of Interest and Fees. All interest and fees shall be calculated
daily on the closing balances in the Loan Account based on the actual number of
days elapsed in year of360 days. For purposes of calculating interest and fees,
if the outstanding daily principal balance of the Revolving Loans' is a credit
balance, such balance shall be deemed to be zero.

2.4 Loan Account; Monthly Accountings. Lender shall maintain a loan account for
Borrower reflecting all advances, charges, expenses and payments made pursuant
to this Agreement (the "Loan Account"), and shall provide Borrower with a
monthly accounting reflecting the activity in the Loan Account. Each accounting
shall be deemed correct, accurate and binding on Borrower and an account stated
(except for reverses and reapplications of payments made and corrections of
errors discovered by Lender), unless Borrower notifies Lender in writing to the
contrary within sixty days after such account is rendered, describing the nature
of any alleged errors or admissions. However, Lender's failure to maintain the
Loan Account or to provide any such accounting shall not affect the legality or
binding nature of any of the Obligations. Interest, fees and other monetary
Obligations due and owing under this Agreement (including fees and other amounts
paid by Lender to issuers of Credit Accommodations) may, in Lender's discretion,
be charged to the Loan Account, and will thereafter be deemed to be Revolving
Loans and will bear interest at the same rate as other Revolving Loans.

3.    SECURITY INTEREST.

3.1 To secure the full payment and performance of all of the Obligations,
Borrower hereby grants to Lender a continuing security interest in all of
Borrower's property and interests in property, whether tangible or intangible,
now owned or in existence or hereafter acquired or arising, wherever located,
including Borrower's interest in all of the following, whether or not eligible
for lending purposes: (i) all Accounts, Chattel Paper, Instruments, Documents,
Goods (including Inventory, Equipment, farm products and consumer goods),
Investment Property, General Intangibles, Deposit Accounts and money, (ii) all
proceeds and products of all of the foregoing (including proceeds of any
insurance policies, proceeds of proceeds and claims against third parties for
loss or any destruction of any of the foregoing) and (iii) all books and records
relating to any of the foregoing.


                                                                               5
<PAGE>

4.    ADMINISTRATION.

4.1 Lock Boxes and Blocked Accounts. Borrower will, at its expense, establish
(and revise from time to time as Lender may require) collection procedures
acceptable to Lender, in Lender's sole discretion, for the collection of checks,
wire transfers and other proceeds of Accounts ("Account Proceeds"), which may
include (i) directing all Account Debtors to send all such proceeds directly to
a post office box designated by Lender either in the name of Borrower (but as to
which Lender has exclusive access) or, at Lender's option, in the name of Lender
(a "Lock Box") or (ii) depositing all Account Proceeds received by Borrower into
one or more bank accounts maintained in Lender's name (each, a "Blocked
Account"), under an arrangement acceptable to Lender with a depository bank
acceptable to Lender, pursuant to which all funds deposited into each Blocked
Account are to be transferred to Lender in such manner, and with such frequency,
as Lender shall specify or (iii) a combination of the foregoing. Borrower agrees
to execute, and to cause its depository banks to execute, such Lock Box and
Blocked Account agreements and other documentation as Lender shall require from
time to time in connection with the foregoing.

4.2 Remittance of Proceeds. Except as provided in Section 4.1, all proceeds
arising from the sale or other disposition of any Collateral shall be delivered,
in kind, by Borrower to Lender in the original form in which received by
Borrower not later than the following Business Day after receipt by Borrower.
Until so delivered to Lender, Borrower shall hold such proceeds separate and
apart from Borrower's other funds and property in an express trust for Lender.
Nothing in this Section 4.2 shall limit the restrictions on disposition of
Collateral set forth elsewhere in this Agreement.

4.3 Application of Payments. Lender may, in its sole discretion, apply, reverse
and re-apply all cash and non-cash proceeds of Collateral or other payments
received with respect to the Obligations, in such order and manner as Lender
shall determine, whether or not the Obligations are due, and whether before or
after the occurrence of a Default or an Event of Default. For purposes of
determining Availability, such amounts will be credited to the Loan Account and
the Collateral balances to which they relate upon Lender's receipt of advice
from Lender's Bank (set forth in Section 11 of Schedule A) that such items have
been credited to Lender's account at Lender's Bank (or upon Lender's deposit
thereof at Lender's Bank in the case of payments received by Lender in kind), in
each case subject to final payment and collection. However, for purposes of
computing interest on the Obligations, such items shall be deemed applied by
Lender three Business Days after Lender's receipt of advice of deposit thereof
at Lender's Bank.

4.4 Notification; Verification. Lender or its designee may, from time to time,
whether or not a Default or Event of Default has occurred or is continuing: (i)
verify directly with the Account Debtors the validity, amount and other matters
relating to the Accounts and Chattel Paper, by means of mail, telephone or
otherwise, either in the name of Borrower or Lender or such other name as Lender
may choose; (ii) notify Account Debtors that Lender has a security interest in
the Accounts and that payment thereof is to be made directly to Lender; and
(iii) at any time after a Default or Event of Default has occurred and is
continuing, demand, collect or enforce payment of any Accounts and Chattel Paper
(but without any duty to do so).


                                                                               6

4.5 Power of Attorney. Borrower hereby grants to Lender an irrevocable power of
attorney, coupled with an interest, authorizing and permitting Lender (acting
through any of its officers, employees, attorneys or agents), at any time
(whether or not a Default or Event of Default has occurred and is continuing,
except as expressly provided below), at Lender's option, but without obligation,
with or without notice to Borrower, and at Borrower's expense, to do any or all
of the following, in Borrower's name or otherwise: (i) execute on behalf of
Borrower any documents that Lender may, in its sole discretion, deem advisable
in order to perfect and maintain Lender's security interests in the Collateral,
to exercise a right of Borrower or Lender, or to fully consummate all the
transactions contemplated by this Agreement and the other Loan Documents
(including such financing statements and continuation financing statements, and
amendments thereto, as Lender shall deem necessary or appropriate) and to file
as a financing statement any copy of this Agreement or any financing statement
signed by Borrower; (ii) after the occurrence of Default or Event of Default and
continuance thereof execute on behalf of Borrower any document exercising,
transferring or assigning any option to purchase, sell or otherwise dispose of
or lease (as lessor or lessee) any real or personal property which is part of
the Collateral or in which Lender has an interest; (iii) after the occurrence of
Default or Event of Default and continuance thereof execute on behalf of
Borrower any invoices relating to any Accounts, any draft against any Account

assignment or satisfaction of mechanic's, materialman's or other Lien; (iv)
execute on behalf of Borrower any notice to any Account Debtor; (v) receive and
otherwise take control in any manner of any cash or non-cash items of payment or
proceeds of Collateral; (vi) endorse Borrower's name on all checks and other
forms of remittances received by Lender; (vii) after the occurrence of Default
or Event of Default, and continuance thereof pay, contest or settle any Lien,
charge, encumbrance, security interest and adverse claim in or to any of the
Collateral, or any judgment based thereon, or otherwise take any action to
terminate or discharge the same; (viii) after the occurrence of a Default or
Event of Default, grant extensions of time to pay, compromise claims relating
to, and settle Accounts, Chattel Paper and General Intangibles for less than
face value and execute all releases and other documents in connection therewith;
(ix) pay any sums required on account of Borrower's taxes (except where
contested by Borrower in good faith and appropriate reserves are maintained) or
to secure the release of any Liens (other than Permitted Liens) therewith; (x)
pay any amounts necessary to obtain, or maintain in effect, any of the insurance
described in Section 5.12; (xi) after the occurrence of Default or Event of
Default, and continuance thereof settle and adjust, and give releases of, any

of Default, change the address for delivery of Borrower's mail and receive and
open all mail addressed to Borrower. Any and all sums paid, and any and all
costs, expenses, liabilities, obligations and reasonable attorneys' fees
incurred, by Lender with respect to the foregoing shall be added to and become
part of the Obligations, shall be payable on demand, and shall bear interest at
a rate equal to the highest interest rate applicable to any of the Obligations.
Borrower agrees that Lender's rights under the foregoing power of attorney or
any of Lender's other rights under this Agreement or the other Loan Documents
shall not be construed to indicate that Lender is in control of the business,
management or properties of Borrower.


                                                                               7
<PAGE>

4.6 Disputes. Borrower shall promptly notify Lender of all disputes or claims
relating to Accounts and Chattel Paper. Borrower will not, without Lender's
prior written consent, compromise or settle any Account or Chattel Paper for
less than the full amount thereof, grant any extension of time of payment of any
Account or Chattel Paper, release (in whole or in part) any Account Debtor or
other person liable for the payment of any Account or Chattel Paper or grant any
credits, discounts, allowances, deductions, return authorizations or the like
with respect to any Account or Chattel Paper; except that prior to the
occurrence of an Event of Default, Borrower may take any of such actions in the
ordinary course of its business, provided that Borrower promptly reports the
same to Lender.

4.7 Invoices. At Lender's request, Borrower will cause all invoices and
statements which it sends to Account Debtors or other third parties to be
marked, in a manner satisfactory to Lender, to reflect Lender's security
interest therein.

4.8 Inventory.

      (a) Returns. Provided that no Event of Default has occurred and is
continuing, if any Account Debtor returns any Inventory to Borrower in the
ordinary course of its business, Borrower will promptly determine the reason for
such return and promptly issue a credit memorandum to the Account Debtor in the
appropriate amount (sending a copy to Lender). After the occurrence of an Event
of Default, Borrower will not accept any return without Lender's prior written
consent. Regardless of whether an Event of Default has occurred, Borrower will
(i) hold the returned inventory in trust for Lender; (ii) segregate all returned
Inventory from all of Borrower's other property; (iii) conspicuously label the
returned inventory as Lender's property; and (iv) immediately notify Lender of
the return of such inventory, specifying the reason for such return, the
location and condition of the returned Inventory and, at Lender's request,
deliver such returned Inventory to Lender at an address specified by Lender.

      (b) Other Covenants. Borrower will not, without Lender's prior written
consent, (i) store any inventory with any warehouseman or other third party
other than as set forth in Section 9(d) of Schedule A or (ii) sell any Inventory
on a sale-or-return, guaranteed sale, consignment, or other contingent basis.
All of the Inventory has been produced only in accordance with the Fair Labor
Standards Act of 1938 and all rules, regulations and orders promulgated
thereunder.

4.9 Access to Collateral, Books and Records. At reasonable times, and on one
Business Day's notice, prior to the occurrence of a Default or an Event of
Default, and at any time and with or without notice after the occurrence of a
Default or an Event of Default, Lender or its agents shall have the right to
inspect the Collateral, and the right to examine and copy Borrower's books and
records. Lender shall take reasonable steps to keep confidential all information
obtained in any such inspection or examination, but Lender shall have the right
to disclose any such information to its auditors, regulatory agencies, attorneys
and participants, and pursuant to any subpoena or other legal process. Borrower
agrees to give Lender access to any or all of Borrower's premises to enable
Lender to conduct such inspections and examinations. Such inspections and
examinations shall be at Borrower's expense and the charge therefor shall be
$850 per person per day (or such higher amount as shall represent Lender's then
current standard charge), plus reasonable out-of-pocket expenses.


                                                                               8
<PAGE>

Lender may, at Borrower's expense, use Borrower's personnel, computer and other
equipment, programs, printed output and computer readable media, supplies and
premises for the collection, sale or other disposition of Collateral to the
extent Lender, in its sole discretion, deems appropriate. Borrower hereby
irrevocably authorizes all accountants and third parties to disclose and deliver
to Lender, at Borrower's expense, all financial information, books and records,
work papers, management reports and other information in their possession
regarding Borrower. Borrower will not enter into any agreement with any
accounting firm, service bureau or third party to store Borrower's books or
records at any location other than Borrower's Address without first obtaining
Lender's written consent (which consent may be conditioned upon such accounting
firm, service bureau or other third party agreeing to give Lender the same
rights with respect to access to books and records and related rights as Lender
has under this Agreement).

5.    REPRESENTATIONS, WARRANTIES AND COVENANTS.

To induce Lender to enter into this Agreement, Borrower represents, warrants and
covenants as follows (it being understood that (i) each such representation and
warranty will be deemed remade as of the date on which each Loan is made and
each Credit Accommodation is provided and shall not be affected by any knowledge
of, or any investigation by, Lender, and (ii) the accuracy of each such
representation, warranty and covenant will be a condition to each Loan and
Credit Accommodation):

5.1 Existence and Authority. Borrower is duly organized, validly existing and in
good standing under the laws of the jurisdiction of its incorporation or
formation. Borrower is qualified and licensed to do business in all
jurisdictions in which any failure to do so would have a material adverse effect
on Borrower. The execution, delivery and performance by Borrower of this
Agreement and all of the other Loan Documents have been duly and validly
authorized, do not violate Borrower's articles or certificate of incorporation,
by-laws or other organizational documents, or any law or any agreement or
instrument or any court order which is binding upon Borrower or its property, do
not constitute grounds for acceleration of any indebtedness or obligation under
any agreement or instrument which is binding upon Borrower or its property, and
do not require the consent of any Person. This Agreement and such other Loan
Documents have been duly executed and delivered by, and are enforceable against,
Borrower, and all other Obligors who have signed them, in accordance with their
respective terms. Sections 9(g) and 9(h) of Schedule A set forth the ownership
of Borrower and the names and ownership of Borrower's Subsidiaries as of the
date of this Agreement.

5.2 Name; Trade Names and Styles. The name of Borrower set forth in the heading
to this Agreement is its correct and complete legal name as of the date hereof.
Listed in Sections 9(a), 9(b) and 9(c) of Schedule A are all prior names of
Borrower and all of Borrower's present and prior trade names. Borrower shall
give Lender at least thirty days' prior written notice before changing its name
or doing business under any other name. Borrower has complied with all laws
relating to the conduct of business under a fictitious business name. Borrower
represents and warrants that (i) each trade name does not refer to another
corporation or other legal entity; (ii) all Accounts invoiced under any such
trade names are owned exclusively by Borrower and are subject to the security
interest of Lender and the other terms of this Agreement and (iii) all schedules
of Accounts,


                                                                               9
<PAGE>

including any sales made or services rendered using any trade name shall show
Borrower's name as assignor.

5.3 Title to Collateral; Permitted Liens. Borrower has good and marketable title
to the Collateral. The Collateral now is and will remain free and clear of any
and all liens, charges, security interests, encumbrances and adverse claims,
except for Permitted Liens. Lender now has, and will continue to have, a
first-priority perfected and enforceable security interest in all of the
Collateral, subject only to the Permitted Liens, and Borrower will at all times
defend Lender and the Collateral against all claims of others. None of the
Collateral which is Equipment is or will be affixed to any real property in such
a manner, or with such intent, as to become a fixture. Except for leases or
subleases as to which Borrower has delivered to Lender a landlord's waiver in
form and substance satisfactory to Lender, Borrower is not a lessee or sublessee
under any real property lease or sublease pursuant to which the lessor or
sublessor may obtain any rights in any of the Collateral, and no such lease or
sublease now prohibits, restrains, impairs or conditions, or will prohibit,
restrain, impair or condition, Borrower's right to remove any Collateral from
the premises. Whenever any Collateral is located upon premises in which any
third party has an interest (whether as owner, mortgagee, beneficiary under a
deed of trust, lien or otherwise), Borrower shall, whenever requested by Lender,
cause each such third party to execute and deliver to Lender, in form and
substance acceptable to Lender, such waivers and subordinations as Lender shall
specify , so as to ensure that Lender's rights in the Collateral are, and will
continue to be, superior to the rights of any such third party. Borrower will
keep in full force and effect, and will comply with all the terms of, any lease
of real property where any of the Collateral now or in the future may be
located.

5.4 Accounts and Chattel Paper. As of each date reported by Borrower, all
Accounts which Borrower has reported to Lender as being Eligible Accounts comply
in all respects with the criteria for eligibility established by Lender and in
effect at such time. All Accounts and Chattel Paper are genuine and in all
respects what they purport to be, arise out of a completed, bona fide and
unconditional and non- contingent sale and delivery of goods or rendition of
services by Borrower in the ordinary course of its business and in accordance
with the terms and conditions of all purchase orders, contracts or other
documents relating thereto, each Account Debtor thereunder had the capacity to
contract at the time any contract or other document giving rise to such Accounts
and Chattel Paper were executed, and the transactions giving rise to such
Accounts and Chattel Paper comply with all applicable laws and governmental
roles and regulations.

5.5 Investment Property. Borrower will take any and all actions required or
requested by Lender, from time to time, to (i) cause Lender to obtain exclusive
control of any Investment Property in a manner acceptable to Lender and (ii)
obtain from any issuers of Investment Property and such other Persons as Lender
shall specify, for the benefit of Lender, written confirmation of Lender's
exclusive control over such Investment Property and take such other actions as
Lender may request to perfect Lender's security interest in such Investment
Property. For purposes of this Section 5.5, Lender shall have exclusive control
of Investment Property if (A) such Investment Property consists of certificated
securities and Borrower delivers such certificated securities to Lender (with
appropriate endorsements if such certificated securities are in registered
form); (B) such Investment Property consists of uncertificated securities and
either (x) Borrower delivers such uncertificated securities to Lender or (y) the
issuer thereof agrees, pursuant to documentation in form and substance


                                                                              10
<PAGE>

satisfactory to Lender, that it will comply with instructions originated by
Lender without further consent by Borrower, and (C) such Investment Property
consists of security entitlements and either (x) Lender becomes the entitlement
holder thereof or (y) the appropriate securities intermediary agrees, pursuant
to documentation in form and substance satisfactory to Lender, that it will
comply with entitlement orders originated by Lender without further consent by
Borrower.

5.6 Place of Business; Location of Collateral. Borrower's Address is Borrower's
chief executive office and the location of its books and records. In addition,
except as provided in the immediately following sentence, Borrower has places of
business and Collateral located only at the locations set forth on Sections 9(d)
and 9(e) of Schedule A. Borrower will give Lender at least thirty days' prior
written notice before opening any additional place of business, changing its
chief executive office or the location of its books and records, or moving any
of the Collateral to a location other than Borrower's Address or one of the
locations set forth in Sections 9(d) and 9(e) of Schedule A, and will execute
and deliver all financing statements and other agreements, instruments and
documents which Lender shall require as a result thereof.

5.7 Financial Condition, Statements and Reports. All financial statements
delivered to Lender by or on behalf of Borrower have been prepared in conformity
with GAAP and completely and fairly reflect the financial condition of Borrower,
at the times and for the periods therein stated. Between the last date covered
by any such financial statement provided to Lender and the date hereof (or, with
respect to the remaking of this representation in connection with the making of
any Loan or the providing of any Credit Accommodation, the date such Loan is
made or such Credit Accommodation is provided), there has been no material
adverse change in the financial condition or business of Borrower. Borrower is
solvent and able to pay its debts as they come due, and has sufficient capital
to carry on its business as now conducted and as proposed to be conducted. All
schedules, reports and other information and documentation delivered by Borrower
to Lender with respect to the Collateral are, or will be, when delivered, true,
correct and complete as of the date delivered or the date specified therein.

5.8 Tax Returns and Payments; Pension Contributions. Borrower has timely filed
all tax returns and reports required by applicable law, has timely paid all
applicable taxes, assessments, deposits and contributions owing by Borrower and
will timely pay all such items in the future as they became due and payable.
Borrower may, however, defer payment of any contested taxes; provided, that
Borrower (i) in good faith contests Borrower's obligation to pay such taxes by
appropriate proceedings promptly and diligently instituted and conducted; (ii)
notifies Lender in writing of the commencement of, and any material development
in, the proceedings; (iii) posts bonds or takes any other steps required to keep
the contested taxes from becoming a Lien upon any of the Collateral and (iv)
maintains adequate reserves therefor in conformity with GAAP .Borrower is
unaware of any claims or adjustments proposed for any of Borrower's prior tax
years which could result in additional taxes becoming due and payable by
Borrower. Borrower has paid, and shall continue to pay, all amounts necessary to
fund all present and future pension, profit sharing and deferred compensation
plans in accordance with their terms, and Borrower has not withdrawn from
participation in, permitted partial or complete termination of, or permitted the
occurrence of any other event with respect to, any such plan which could result
in any liability of Borrower, including any liability to the Pension Benefit
Guaranty Corporation or any other governmental agency.


                                                                              11
<PAGE>

5.9 Compliance with Laws. Borrower has complied in all material respects with
all provisions of all applicable laws and regulations, including those relating
to Borrower's ownership of real or personal property, the conduct and licensing
of Borrower's business, the payment and withholding of taxes, ERISA and other
employee matters, safety and environmental matters.

5.10 Litigation. Section 9(1) of Schedule A discloses all claims, proceedings,
litigation or investigations pending or (to the best of Borrower's knowledge)
threatened against Borrower. There is no claim, suit, litigation, proceeding or
investigation pending or (to the best of Borrower's knowledge) threatened by or
against or affecting Borrower in any court or before any governmental agency (or
any basis therefor known to Borrower) which may result, either separately or in
the aggregate, in any material adverse change in the financial condition or
business of Borrower, or in any material impairment in the ability of Borrower
to carry on its business in substantially the same manner as it is now being
conducted. Borrower will promptly inform Lender in writing of any claim,
proceeding, litigation or investigation in the future threatened or instituted
by or against Borrower.

5.11 Use of Proceeds. All proceeds of all Loans will be used solely for lawful
business purposes.

5.12 Insurance. Borrower will at all times carry property, liability and other
insurance, with insurers acceptable to Lender, in such form and amounts, and
with such deductibles and other provisions, as Lender shall require, and
Borrower will provide evidence of such insurance to Lender, so that Lender is
satisfied that such insurance is, at all times, in full force and effect. Each
property insurance policy shall name Lender as loss payee and shall contain a
lender's loss payable endorsement in form acceptable to Lender, each liability
insurance policy shall name Lender as an additional insured, and each business
interruption insurance policy shall be collaterally assigned to Lender, all in
form and substance satisfactory to Lender. All policies of insurance shall
provide that they may not be cancelled or changed without at least thirty days'
prior written notice to Lender, shall contain breach of warranty coverage, and
shall otherwise be in form and substance satisfactory to Lender. Upon receipt of
the proceeds of any such insurance, Lender shall apply such proceeds in
reduction of the Obligations as Lender shall determine in its sole discretion.
Borrower will promptly deliver to Lender copies of all reports made to insurance
companies.

5.13 Financial and Collateral Reports. Borrower has kept and will keep adequate
records and books of account with respect to its business activities and the
Collateral in which proper entries are made in accordance with GAAP reflecting
all its financial transactions, and will cause to be prepared and furnished to
Lender the following (all to be prepared in accordance with GAAP , unless
Borrower's certified public accountants concur in any change therein and such
change is disclosed to Lender):

      (a) Collateral Reports. On or before the fifteenth day of each month, an
aging of Borrower's Accounts, Chattel Paper and notes receivable, and weekly
Inventory reports, all in such form, and together with such additional
certificates, schedules and other information with respect to the Collateral or
the business of Borrower or any Obligor, as Lender shall request; provided, that
Borrower's failure to execute and deliver the same shall not affect or limit
Lender's security interests and other rights in any of the Accounts, nor shall
Lender's failure to advance or lend against a


                                                                              12
<PAGE>

therein. Together with each such schedule, Borrower shall furnish Lender with
copies (or, at Lender's request, originals) of all contracts, orders, invoices,
and other similar documents, and all original shipping instructions, delivery
receipts, bills of lading, and other evidence of delivery, for any goods the
sale or disposition of which gave rise to such Accounts, and Borrower warrants
the genuineness of all of the foregoing. In addition, Borrower shall deliver to
Lender the originals of all Instruments, Chattel Paper, security agreements,
guaranties and other documents and property evidencing or securing any Accounts,
immediately upon receipt thereof and in the same form as received, with all
necessary endorsements. Lender may destroy or otherwise dispose of all
documents, schedules and other papers delivered to Lender pursuant to this
Agreement (other than originals of Instruments, Chattel Paper, security
agreements, guaranties and other documents and property evidencing or securing

their return in writing in advance and arranges for their return to Borrower at
Borrower's expense.

the close of each fiscal year of Borrower, unqualified (except for a
qualification for a change in accounting principles with which the accountant

<PAGE>

      (g) Other Information. Such other data and information (financial and
otherwise) as Lender, from time to time, may reasonably request, bearing upon or
related to the Collateral or Borrower's and each of its Subsidiary's financial
condition or results of operations.

5.14 Litigation Cooperation. Should any third-party suit or proceeding be
instituted by or against Lender with respect to any Collateral or in any manner
relating to Borrower, Borrower shall, without expense to Lender, make available

in good working condition, ordinary wear and tear excepted, and Borrower will
not use the Collateral for any unlawful purpose. Borrower will immediately

any investigation, action, suit, proceeding or claim relating to the Collateral
or which may result in an adverse impact upon Borrower's business, assets or
financial condition.

5.16 Notification of Changes. Borrower will promptly notify Lender in writing of
any change in its officers or directors, the opening of any new bank account or
other deposit account, or any material adverse change in the business or
financial affairs of Borrower or the existence of any circumstance which would
make any representation or warranty of Borrower untrue in any material respect
or constitute a material breach of any covenant of Borrower.

5.17 Year 2000 Compliance. Borrower has (i) initiated a review and assessment of
all areas within its and each of its Affiliates' business and operations
(including those affected by suppliers and vendors) that could be adversely

used by Borrower or any of its Affiliates (or its suppliers and vendors) may be
unable to recognize and perform properly date-sensitive functions involving
certain dates prior to and any date after December 31, 1999), (ii) developed a
plan and timeline for addressing the Year 2000 Problem on a timely basis, and
(iii) to date, implemented that plan in accordance with that timetable. Borrower

suppliers and vendors) that are material to its or any of its Affiliates'
business and operations will on a timely basis be able to perform properly
date-sensitive functions for all dates before and after January 1,2000 (that is,
be "Year 2000 Compliant"), except to the extent that a failure to do so could
not reasonably be expected to have a material adverse effect on Borrower or the
Property. Borrower will promptly notify Lender in the event the Borrower
discovers or determines that any computer application (including those of its
suppliers and vendors) that is material to its or any of its Affiliates'
business and operations will not be Year 2000 Compliant on a timely basis,
except to the extent that such failure could not reasonably be expected to have
a material adverse effect.

and execute or cause to be executed and delivered to Lender all promissory
notes, security agreements, agreements with landlords, mortgagees and processors
and other bailees, subordination and intercreditor agreements and other
agreements, instruments and documents as Lender may request from time to


                                                                              14

Subsidiary or acquire any interest in any Person; (ii) acquire any assets except

6.    RELEASE AND INDEMNITY.

6.1 Release. Borrower hereby releases Lender and its Affiliates and their
respective directors, officers, employees, attorneys and agents and any other
Person affiliated with or representing Lender (the "Released Parties") from any
and all liability arising from acts or omissions under or pursuant to this
Agreement, whether based on errors of judgment or mistake of law or fact, except
for those arising from willful misconduct or gross negligence. However, in no
circumstance will any of the Released Parties be liable for lost profits or
other special or consequential damages. Such release is made on the date hereof
and remade upon each request for a Loan or Credit Accommodation by Borrower.
Without limiting the foregoing:

      (a) Lender shall not be liable for (i) any shortage or discrepancy in,

and authority to clear and resolve any questions of noncompliance of documents,
to give any instructions as to acceptance or rejection of any documents or
goods, to execute for Borrower's account any and all applications for steamship

and to agree to any amendments, renewals, extensions, modifications, changes or
cancellations of any of the terms or conditions of any of the Credit
Accommodations or applications and other documentation pertaining thereto.

6.2 Indemnity. Borrower hereby agrees to indemnify the Released Parties and hold
them harmless from and against any and all claims, debts, liabilities, demands,
obligations, actions, causes of action, penalties, costs and expenses (including
attorneys' fees), of every nature, character and description, which the Released
Parties may sustain or incur based upon or arising out of any of the
transactions contemplated by this Agreement or the other Loan Documents or any
of the Obligations, including any transactions or occurrences relating to the
issuance of any Credit Accommodation, the Collateral relating thereto, any
drafts thereunder and any errors or omissions relating thereto (including any
loss or claim due to any action or inaction taken by the issuer of any Credit
Accommodation) (and for this purpose any charges to Lender by any issuer of
Credit Accommodations shall be conclusive as to their appropriateness and may be
charged to the Loan Account), or any other matter, cause or thing whatsoever
occurred, done, omitted or suffered to be done by Lender relating to Borrower or
the Obligations (except any such amounts sustained or incurred as the result of
the willful misconduct or gross negligence of the Released Parties). Not
withstanding any provision in this Agreement to the contrary, the indemnity
agreement set forth in this Section shall survive any termination of this
Agreement.

7.    TERM.

7.1 Maturity Date. Lender's obligation to make Loans and to provide Credit
Accommodations under this Agreement shall initially continue in effect until the
Initial Maturity Date set forth in Section 7 of Schedule A (the "Initial Term");
provided, that such date may be extended (the Initial Maturity Date, as it may
be so extended, being referred to as the "Maturity Date") for successive
additional terms (each a "Renewal Term") by agreement of Lender and Borrower.
This Agreement and the other Loan Documents and Lender's security interests in
and Liens upon the Collateral, and all representations, warranties and covenants
of Borrower contained herein and therein, shall remain in full force and effect
after the Maturity Date until all of the monetary Obligations are indefeasibly
paid in full.

7.2 Early Termination. Lender's obligation to make Loans and to provide Credit
Accommodations under this Agreement may be terminated prior to the Maturity Date
as follows: (i) by Borrower, effective thirty business days after written notice
of termination is given to Lender or (ii) by Lender at any time after the
occurrence of an Event of Default, without notice, effective immediately;
provided, that if any Affiliate of Borrower is also a party to a financing
arrangement with Lender, no such early termination shall be effective unless
such Affiliate simultaneously terminates its financing arrangement with Lender.
If so terminated under this Section 7.2, Borrower shall pay to Lender (i) an
early termination fee (the "Early Termination Fee") in the amount set forth in
Section 6(j) of Schedule A plus (ii) any earned but unpaid Facility Fee plus
(iii) any fees or payments due under Schedule D. Such fee shall be due and
payable on the effective date of termination and thereafter shall bear interest
at a rate equal to the highest rate applicable to any of the Obligations. In
addition, if Borrower so terminates and repays the Obligations without having


                                                                              17
<PAGE>

provided Lender with at least thirty days' prior written notice thereof, an
additional amount equal to thirty days of interest at the applicable Interest
Rate(s), based on the average outstanding amount of the Obligations for the six
month period immediately preceding the date of termination.

7.3 Payment of Obligations. On the Maturity Date or on any earlier effective
date of termination, Borrower shall pay in full all Obligations, whether or not
all or any part of such Obligations are otherwise then due and payable. Without
limiting the generality of the foregoing, if, on the Maturity Date or on any
earlier effective date of termination, there are any outstanding Credit
Accommodations, then on such date Borrower shall provide to Lender cash
collateral in an amount equal to 110% of the Credit Accommodation Balance to
secure all of the Obligations (including estimated attorneys' fees and other
expenses) relating to said Credit Accommodations pursuant to a cash pledge
agreement in form and substance satisfactory to Lender. At such time as there is
no Credit Accommodation Balance, such cash collateral shall be promptly returned
to Borrower.

7.4 Effect of Termination. No termination shall affect or impair any right or
remedy of Lender or relieve Borrower of any of the Obligations until all of the
monetary Obligations have been indefeasibly paid in full. Upon indefeasible
payment and performance in full of all of the monetary Obligations (and the
provision of cash collateral with respect to any Credit Accommodation Balance as
required by Section 7.3) and termination of this Agreement, Lender shall
promptly deliver to Borrower termination statements, requests for reconveyances
and such other documents as may be reasonably required to terminate Lender's
security interests in the Collateral.

8.    EVENTS OF DEFAULT AND REMEDIES.

8.1 Events of Default. The occurrence of any of the following events shall
constitute an "Event of Default" under this Agreement, and Borrower shall give

security agreement or other agreement, instrument or document executed and
delivered by (A) Borrower with, or in favor of, any Person other than Lender or

evidenced thereby to accelerate the maturity of the same; (vii) the dissolution,
death, termination of existence in good standing, insolvency or business failure
or suspension or cessation of business as usual of Borrower or any Obligor (or
of any general partner of Borrower or any Obligor if it is a partnership) or the

potential penalties or remedies sought or available include forfeiture of any
property of Borrower or such Obligor; (xii) if there is any change in the chief

performance of the Obligations is impaired. Notwithstanding any
misrepresentations or breach of any covenant or other obligations contained in
Sections 5.1 (the first two sentences), 5.8,5.9, 5.13(c), (d), (f), and (g), and
5.14 of this Agreement such misrepresentations or breach shall not constitute an
Event of Default until ten (10) days after the earlier of (A) Borrower has
knowledge of, or should have had knowledge of, the existence of such
misrepresentation or breach, or (B) notice by Lender to Borrower of such
misrepresentation or breach.

8.2 Remedies. Upon the occurrence of any Default, and at any time thereafter
(unless such Default has been waived by Lender in writing), Lender, at its
option, may cease making Loans or otherwise extending credit to Borrower under
this Agreement or any other Loan Document. Upon the occurrence of any Event of
Default, and at any time thereafter (unless such Event of Default has been
waived by Lender in writing), Lender, at its option, and without notice or

do anyone or more of the following: (i) cease making Loans or otherwise
extending credit to Borrower under this Agreement or any other Loan Document;

due, payable and performable, notwithstanding any deferred or installment

may be found, and for that purpose Borrower hereby authorizes Lender, without
judicial process, to enter onto any of Borrower's premises without interference
to search for, take possession of, keep, store, or remove any of the Collateral,
and remain (or cause a custodian to remain) on the premises in exclusive control
thereof, without charge for so long as Lender deems it reasonably necessary in
order to complete the enforcement of its rights under this Agreement or any
other agreement; provided, that if Lender seeks to take possession of any of the
Collateral by court process, Borrower hereby irrevocably waives (A) any bond and
any surety or security relating


                                                                              19
<PAGE>

thereof and (C) any requirement that Lender retain possession of, and not
dispose of, any such Collateral until after trial or final judgment; (iv)

to Lender at one or more places designated by Lender which are reasonably
convenient to Lender and Borrower, and to remove the Collateral to such

manufacturing or repair of any Collateral prior to a disposition thereof and,
for such purpose and for the purpose of removal, Lender shall have the right to
use Borrower's premises, vehicles and other Equipment and all other property
without charge; (vi) sell, lease or otherwise dispose of any of the Collateral,
in its condition at the time Lender obtains possession of it or after further
manufacturing, processing or repair, at one or more public or private sales, in
lots or in bulk, for cash, exchange or other property, or on credit (a "Sale"),
and to adjourn any such Sale from time to time without notice other than oral
announcement at the time scheduled for Sale (and, in connection therewith, (A)
Lender shall have the right to conduct such Sale on Borrower's premises without
charge, for such times as Lender deems reasonable, on Lender's premises, or
elsewhere, and the Collateral need not be located at the place of Sale; (B)
Lender may directly or through any of its Affiliates purchase or !ease any of
the Collateral at any such public disposition, and if permissible under
applicable law, at any private disposition and (C) any Sale of Collateral shall
not relieve Borrower of any liability Borrower may have if any Collateral is
defective as to title, physical condition or otherwise at the time of sale);
(vii) demand payment of and collect any Accounts, Chattel Paper, Instruments and
General Intangibles included in the Collateral and, in connection therewith,
Borrower irrevocably authorizes Lender to endorse or sign Borrower's name on all
collections, receipts, Instruments and other documents, to take possession of
and open mail addressed to Borrower and remove therefrom payments made with
respect to any item of Collateral or proceeds thereof and, in Lender's sole
discretion, to grant extensions of time to pay, compromise claims and settle
Accounts, General Intangibles and the like for less than face value; and (viii)
demand and receive possession of any of Borrower's federal and state income tax
returns and the books and records utilized in the preparation thereof or
relating thereto. In addition to the foregoing remedies, upon the occurrence of
any Event of Default resulting from a breach of any of the financial covenants
set forth in Section 5.19, Lender may, at its option, upon not less than ten
days' prior notice to Borrower, reduce any or all of the Advance Rates set forth
in Section l(b) of Schedule A to the extent Lender, in its sole discretion,
deems appropriate. In addition to the rights and remedies set forth above,
Lender shall have all the other rights and remedies accorded a secured party
after default under the UCC and under all other applicable laws, and under any
other Loan Document, and all of such rights and remedies are cumulative and
non-exclusive. Exercise or partial exercise by Lender of one or more of its
rights or remedies shall not be deemed an election or bar Lender from subsequent
exercise or partial exercise of any other rights or remedies. The failure or
delay of Lender to exercise any rights or remedies shall not operate as a waiver
thereof, but all rights and remedies shall continue in full force and effect
until all of the Obligations have been fully paid and performed. If notice of
any sale or other disposition of Collateral is required by law, notice at least
seven days prior to the sale designating the time and place of sale in the case

Lender on credit terms or for future delivery, the Obligations shall not be
reduced as a result thereof until payment is collected by Lender.

proceeds realized as the result of any Sale shall be applied by Lender to the
Obligations in such order as Lender shall determine in its sole discretion. Any
surplus shall be paid to Borrower or other persons legally entitled thereto; but
Borrower shall remain liable to Lender for any deficiency. If Lender, in its
sole discretion, directly or indirectly enters into a deferred payment or other
credit transaction with any purchaser at any Sale, Lender shall have the option,
exercisable at any time, in its sole discretion, of either reducing the
Obligations by the principal amount of the purchase price or deferring the
reduction of the Obligations until the actual receipt by Lender of the cash
therefor .

at a rate equal to the highest interest rate applicable to any of the
Obligations.

be binding upon and inure to the benefit of the respective successors, assigns,
heirs, beneficiaries and representatives of Borrower and Lender; provided, that

without the prior written consent of Lender, and any prohibited assignment shall
be void. No consent by Lender to any assignment shall release Borrower from its
liability for any of the Obligations. Lender shall have the right to assign all
or any of its rights and obligations under the Loan Documents, and to sell
participating interests therein, to one or more other Persons, and Borrower
agrees to execute all agreements, instruments and documents requested by Lender

                                   Schedule D

This Schedule shall apply to all LIBOR Loans (as hereinafter defined)

      "Business Day" shall mean any day not a Saturday, Sunday or legal holiday,

the date of such Loan and ending on the numerically corresponding day (or if
there is no numerically corresponding day, the last day) of the calendar month
that is one month (30 day rate) or two months (60 day rate) thereafter. LIBOR
Loans shall be available only in thirty and sixty day periods. No Interest
period may be selected for a LIBOR Loan which expires later than the Maturity
Date. If the Borrower fails to specify the applicable Interest Period in respect
of a LIBOR Loan, such Loan shall automatically convert to a Prime Rate Loan upon
the termination of the existing Interest Period.

      "LIBOR Rate" shall mean, with respect to any LIBOR Loan for any Interest
Period, the rate appearing on Page 3750 of the Telerate Service (or on any
successor or substitute comparable to those currently provided on such page of
such Service, as determined by the Lender from time to time for purposes of
providing quotations of interest rates applicable to dollar deposits in the
London interbank market) (rounded upwards, if necessary, to the next 1/100 of 1
%) at approximately 11 :00 a.m., London time, two Business Days prior to the
commencement of such Interest period, as the rate for dollar deposits with a
maturity comparable to such Interest Period. In the event that such rate is not
available at such time for any reason, then the LIBOR Rate with respect to such
LIBOR Borrowing for such Interest period shall be the rate at which dollar
deposits approximately equal in principal amount to the amount of the applicable
Borrowing and for a maturity comparable to such Interest Period are offered by
the principal London office of the Lender in immediately available funds in the
London interbank market at approximately 11 :00 am., London time, two Business
Days prior to the commencement so such Interest Period.

"LIBOR Loan" means a Loan bearing interest in accordance with Section 3(a)(i)
of this Agreement.

      "Prime Rate Loan" shall mean a Loan bearing interest in accordance with
Section 3(a)(ii) of this Agreement.

Subject to the provisions of Section 2.2 and this Schedule D, the Borrower may,
with three (3) Business Days' notice to the Lender with respect to LIBOR Loans,
prepay the outstanding amount of any Loan in whole or in part with accrued
interest to the date of such prepayment oh the amount prepaid; provided however,
that each partial prepayment of any Loan shall be in a principal


                                                                          B-10
<PAGE>

amount not less than $100,000; and provided, further, that any prepayment of
any or LIBOR Loan shall be made on, and only on, the last day of an Interest

$1,000,000. Each such notice ("Notice of Borrowing") shall specify (i) the
requested date of such Loan, (ii) the requested Type of Loan, and (iii) the
Interest Period for such Loan, if applicable. Borrow shall not be permitted to
maintain more than five (5) LIBOR Loans at any time.

      In the event that the Lender shall have reasonably determined that on any
date for determining the LIBOR Rate for any Interest Period, by reason of any
changes arising after the date of this Agreement affecting the London interbank
market, or the Lender's position in such market, adequate and fair means do not
exist for ascertaining the applicable interest rate on the basis provided for in
the definition of LIBOR Rate, then, and in any such event, the Lender shall
forthwith give notice (by telephone confirmed in writing) to the Borrower. Until
the Lender notifies the Borrower that the circumstances giving rise to the
suspension described herein no longer exist, the obligations of the Lender to
make LIBOR Loans shall be suspended and during the period of such suspension
Loans shall be made at the other rates provided for hereunder which continue to
be available. In such event, all LIBOR Loans shall thereupon automatically
convert to Prime Rate Loans.

      Notwithstanding any other provision herein, if after the date of this
Agreement any change in applicable law or regulation or in the interpretation or
administration thereof by any governmental authority charged with the
interpretation or administration thereof (whether or not having the force of
law) shall (i) subject the Lender (which shall, for the purpose of this Section
include any lending office of the Lender) to any tax with respect to any amount
paid or to be paid to the Lender with respect to any LIBOR Loans made by the
Lender to the Borrower (other than (x) taxes imposed on the overall net income
or net profits of the Lender and (y) franchise taxes imposed on the Lender, in
either case by the jurisdiction in which the Lender is organized or in which the
Lender has its principal office or its lending office with respect to such LIBOR
Loan or any political subdivision or taxing authority of either thereof); (ii)
change the basis of taxation of payments to the Lender of the principal of or
interest on any LIBOR Loan or any other fees or amounts payable hereunder (other
than taxes imposed on the overall net income or net profits of the Lender by the
jurisdiction in which the Lender is organized or in which the Lender has its
principal office or lending office or by any political subdivision or taxing
authority therein); (iii) impose, modify or deem applicable any reserve, special
deposit or similar requirement against assets of, deposits with or for the
account of, or loans or loan commitments extended by, the Lender; or (iv) impose
on the Lender or the London interbank market any other condition affecting this
Agreement or LIBOR Loans made by the Lender; and the result of any of the
foregoing shall be to increase the actual cost to the Lender of making or
maintaining any LIBOR Loan, or to reduce the amount of any payment (whether of
principal, interest or otherwise) receivable by the Lender or to require the
Lender to make any payment, in each case by or in an amount which the Lender in
its sole judgment shall deem material, in respect of any LIBOR Loan, the
Borrower shall pay to the Lender, upon the Lender's demand, such additional


                                                                          B-11
<PAGE>

amount or amounts as will compensate the Lender for such additional costs or
reduction. The Lender agrees to give notice to the Borrower of any such change
in law, regulation, interpretation or administration with reasonable promptness
after becoming actually aware thereof and of the applicability thereof to this
Agreement or the Note. In the event that the Lender shall reasonably determine
at any time that by reason of a change in Regulation D the Lender is required to
maintain reserves in respect of LIBOR Loans or liabilities during any period
that it has a LIBOR Loan outstanding, then the Lender shall promptly notify the
Borrower by written notice (or telephone notice promptly in writing) specifying
the additional amounts required to indemnify the Lender against the cost of
maintaining such reserves (such written notice to provide a computation of such
additional amounts) and the Borrower shall directly pay to the Lender such
specified amounts as additional interest at the time that it is otherwise
required to pay interest in respect of such LIBOR Loan or, if later, on demand.

      If, after the date of this Agreement, the Lender shall have determined
that the adoption of any applicable law, rule, regulation or guideline regarding
capital adequacy, or any change therein, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by the Lender (or its relevant lending office) with any request or directive
regarding capital adequacy (whether or not having the force of law) of any such
authority, central bank or comparable agency, has or will have the effect of
reducing the rate of return on the Lender's capital as a consequence of its
obligations hereunder to a level below that which the Lender could have achieved
but for such adoption, change or compliance (taking into consideration the
Lender's policies with respect to capital adequacy) then from time to time, the
Borrower shall pay to the Lender such additional amount or amounts as will
compensate the Lender for such reduction. The Lender agrees to give notice to
the Borrower of any adoption of, change in, or change in interpretation or
administration of, any such law, rule, regulation or guideline with reasonable
promptness after becoming actually aware thereof and of the applicability
thereof to the Loans.

      Failure on the part of the Lender to demand compensation for any increased
costs, reduction in amounts received or receivable or reduction in the rate of
return earned on the Lender's capital with respect to any Interest Period, shall
not constitute a waiver of the Lender's rights to demand compensation for any
increased costs or reduction in amounts received or receivable or reduction in
rate of return with respect to any subsequent Interest Period.

      Notwithstanding anything to the contrary herein contained, if any change
in any law or regulation or in the interpretation thereof by any governmental
authority charged with the administration or interpretation thereof shall make
it unlawful for the Lender to make or maintain any LIBOR Loan or to give effect
to its obligations to make LIBOR Loans as contemplated hereby, then, by five (5)
Business Days' prior written notice to Borrower, the Lender may:

                  9.11.0.0.0.1 declare that LIBOR Loans will not thereafter be
made by the Lender hereunder, whereupon the Borrower shall be prohibited from
requesting LIBOR Loans from the Lender hereunder unless such declaration is
subsequently withdrawn; and


                                                                         B-12
<PAGE>

                  9.11.0.0.0.2require that all outstanding LIBOR Loans, as the
case may be, made by it be converted to Prime Rate Loans, in which event all
such LIBOR Loans shall be automatically converted to Prime Rate Loans as of the
date of such notice.

      Borrower shall indemnify the Lender against any loss or reasonable expense
in connection with any LIBOR Loan made or requested to be made (including, but
not limited to, any loss or reasonable expense sustained or incurred or to be
sustained or incurred in liquidating or employing deposits from third parties
acquired to affect or maintain any Loan or part thereof as a LIBOR Loan but
excluding loss of anticipated profits) which the Lender may sustain or incur as
a consequence of the following events (regardless of whether such events occur
as a result of the occurrence of an Event of Default or the exercise of any
right or remedy of the Lender under this Agreement or any other agreement, or at
law): any failure of the Borrower to fulfill on the date of borrowing hereunder
the applicable conditions applicable to it, any failure of the Borrower to
borrow hereunder after irrevocable Notice of Borrowing has been given, any
payment, prepayment or conversion of a LIBOR Loan on a date other than the last
day of the relevant Interest Period or any default in payment or prepayment of
the principal amount of any Loan or any part thereof or interest accrued
thereon, as and when due and payable (at the due date thereof, by irrevocable
notice of prepayment or otherwise). The Lender shall provide to the Borrower a
statement, signed by an officer of the Lender, explaining any loss or expense
and setting forth, if applicable, the computation pursuant to the preceding
sentence, and such statement shall be prima facie evidence thereof. The Borrower
shall pay the Lender the amount shown as due on any such statement within thirty
(30) days after the receipt of the same.
