the term of this Agreement which, in the aggregate at any time outstanding, will
not exceed the Maximum Loan Amount.

          (b) If the Borrower does not pay any interest, fees, costs or charges
to the Lender when due, the Borrower shall thereby be deemed to have requested,
and the Lender is hereby authorized at its discretion to make and charge to the

amount equal to such unpaid interest, fees, costs or charges.

          (c) Any sums expended by the Lender due to the Borrower's failure to
perform or comply with its obligations under this Agreement, shall be charged to
the Borrower's account as a Credit Advance and added to the Obligations.

     3. Repayment of the Credit Advances

          The Borrower shall be required to repay within sixty (60) days of a
written demand by the Lender: (i) the aggregate outstanding principal balance of
the Credit Advances made by the Lender to the Borrower hereunder together with
any accrued and unpaid interest, fees and charges; and (ii) all other amounts
owed to the Lender under this Agreement and the Ancillary Agreements.
Notwithstanding the aforesaid, Borrower may offset any payments due hereunder by
reducing the amounts due hereunder by any amounts that may be due to Borrower by
Lender under the Loan and Security Agreement dated the same day hereof between
the parties (the "Mirror Agreement") wherein Borrower is a lender to the Lender.

     4. Procedure for Credit Advances All of the Credit Advances shall be
disbursed from whatever location and by whatever means the Lender may determine,
in its sole discretion, from time to time and, together with any and all other
Obligations of the Borrower to the Lender, shall be charged to the Borrower's
account on the Lender's books. Any and all Obligations due and owing hereunder
may be charged to the Borrower's account and shall constitute Credit Advances.

for each day they are outstanding at the Contract Rate.

          (b) Interest shall be (i) computed on the basis of actual days elapsed

Borrower's account for said interest.

          (c) Upon the occurrence and during the continuance of an Event of
Default, interest shall be payable at the Default Rate.

          (d) Notwithstanding the foregoing, in no event shall interest exceed

provision of this

                                        3

<PAGE>

Agreement or an Ancillary Agreement is in contravention of any such law or
regulation, such provision shall be deemed amended to provide for interest at
said maximum rate and any excess amount shall either be applied, at the Lender's
option, to the outstanding Loans in such order as the Lender shall determine or
refunded by the Lender to the Borrower.

          (e) The Borrower shall pay principal, interest and all other amounts
payable hereunder, or under any Ancillary Agreement, without any deduction
whatsoever, including, but not limited to, any deduction for any set-off or
counterclaim.

     6. Security Interest.

          (a) To secure the prompt payment to the Lender of the Obligations, the
Borrower hereby assigns, pledges and grants to the Lender a continuing security
interest in and to the Collateral, whether now owned or existing or hereafter
acquired or arising and wheresoever located, whether or not the same is subject
to Article 9 of the UCC, but not including any assets of any current or future
Affiliate of Borrower other than Receivables of Borrower. All of the Borrower's
ledger sheets, files, records, books of account, business papers and documents
relating to the Collateral shall, until delivered to or removed by the Lender,
be kept by the Borrower in trust for the Lender until all Obligations have been
paid in full. Each confirmatory assignment schedule or other form of assignment
hereafter executed by the Borrower shall be deemed to include the foregoing
grant, whether or not the same appears therein.

          (b) The Lender may, at its discretion, file one or more financing
statements disclosing the Lender's security interest in the Collateral without
the Borrower's signature appearing thereon or the Lender may sign on the
Borrower's behalf as provided in paragraph 11 herein. The parties agree that a
carbon, photographic or other reproduction of this Agreement shall be sufficient
as a financing statement. If any Receivable becomes evidenced by a promissory
note or any other instrument for the payment of money, the Borrower will
immediately deliver such instrument to the Lender appropriately endorsed.

     7. Covenants Concerning the Collateral During the Term, the Borrower
covenants that it shall:

          (a) not dispose of any of the Collateral whether by sale, lease or
otherwise except for collection of the Collateral in the ordinary course of
business during any fiscal year; and to the extent that the amount of the Loan
exceeds the Maximum Loan Amount upon collection of the Collateral, the proceeds
of such Collateral shall be remitted to the Lender in reduction of the
Obligations;

          (b) not encumber, mortgage, pledge, assign or grant any security
interest in any of the Collateral to anyone other than the Lender;

          (c) keep and maintain the original and other documents evidencing, and
relating to, the agreements and transactions which gave rise to the Collateral,
including without limitation, all original orders and invoices;

          (d) perform all other steps reasonably requested by the Lender to
create and maintain in the Lender's favor a valid perfected security interest in
all of the Collateral; and

                                        4

<PAGE>

          (e) defend the Collateral against the claims and demands of all
parties.

     8. Representations, Warranties and Covenants The Borrower represents,
warrants (each of which such representations and warranties shall be deemed
repeated upon the making of a request for a Credit Advance and made as of the
time of each Credit Advance made hereunder), and covenants that:

          (a) The Borrower is a corporation duly organized and validly existing
under the laws of the State of Delaware and duly qualified and in good standing

business requires such qualification;

governmental charges or levies imposed upon it;

          (e) it will not (i) create, incur, assume or suffer to exist any
indebtedness (other than in the ordinary course) secured by the Collateral; or

capital and;

unpaid and until the Obligations have been fully satisfied.

     15. Remedies. The Lender has the right to demand repayment in full of all

The Lender will return any excess to the Borrower and the Borrower shall remain
liable to the Lender for any deficiency.

     16. Waiver; Cumulative Remedies. Failure by the Lender to exercise any
right, remedy or option under this Agreement or any supplement hereto or any
other agreement between the Borrower and the Lender or delay by the Lender in
exercising the same, will not operate as a waiver, and no waiver by the Lender
will be effective unless it is in writing and then only to the extent
specifically stated. The Lender's rights and remedies under this Agreement will
be cumulative and not exclusive of any other right or remedy that the Lender may
have.

     17. Application of Payments. The Borrower irrevocably waives the right to
direct the application of any and all payments at any time or times hereafter
received by the Lender from or on the Borrower's behalf and the Borrower hereby
irrevocably agrees that the Lender shall have the continuing exclusive right to
apply and reapply any and all payments received at any time or times hereafter

deem advisable notwithstanding any entry by the Lender upon any of the Lender's
books and records.

written demand by the Lender: (i) the aggregate outstanding principal balance of
the Credit Advances made by the Lender to the Borrower hereunder together with
any accrued and unpaid interest, fees and charges; and (ii) all other amounts
owed to the Lender under this Agreement and the Ancillary Agreements.

reducing the amounts due hereunder by any amounts that may be due to Borrower by
Lender under the Loan and Security Agreement dated the same day hereof between
the parties (the "Mirror Agreement") wherein Borrower is a lender to the Lender.

disbursed from whatever location and by whatever means the Lender may determine,
in its sole discretion, from time to time and, together with any and all other
Obligations of the Borrower to the Lender, shall be charged to the Borrower's

<PAGE>

Agreement or an Ancillary Agreement is in contravention of any such law or
regulation, such provision shall be deemed amended to provide for interest at
said maximum rate and any excess amount shall either be applied, at the Lender's
option, to the outstanding Loans in such order as the Lender shall determine or
refunded by the Lender to the Borrower.

          (e) The Borrower shall pay principal, interest and all other amounts
payable hereunder, or under any Ancillary Agreement, without any deduction
whatsoever, including, but not limited to, any deduction for any set-off or
counterclaim.

     6. Security Interest.

          (a) To secure the prompt payment to the Lender of the Obligations, the
Borrower hereby assigns, pledges and grants to the Lender a continuing security
interest in and to the Collateral, whether now owned or existing or hereafter
acquired or arising and wheresoever located, whether or not the same is subject
to Article 9 of the UCC, but not including any assets of any current or future
Affiliate of Borrower other than Receivables of Borrower. All of the Borrower's
ledger sheets, files, records, books of account, business papers and documents
relating to the Collateral shall, until delivered to or removed by the Lender,
be kept by the Borrower in trust for the Lender until all Obligations have been
paid in full. Each confirmatory assignment schedule or other form of assignment
hereafter executed by the Borrower shall be deemed to include the foregoing
grant, whether or not the same appears therein.

          (b) The Lender may, at its discretion, file one or more financing
statements disclosing the Lender's security interest in the Collateral without
the Borrower's signature appearing thereon or the Lender may sign on the
Borrower's behalf as provided in paragraph 11 herein. The parties agree that a
carbon, photographic or other reproduction of this Agreement shall be sufficient
as a financing statement. If any Receivable becomes evidenced by a promissory
note or any other instrument for the payment of money, the Borrower will
immediately deliver such instrument to the Lender appropriately endorsed.

     7. Covenants Concerning the Collateral During the Term, the Borrower
covenants that it shall:

          (a) not dispose of any of the Collateral whether by sale, lease or
otherwise except for collection of the Collateral in the ordinary course of
business during any fiscal year; and to the extent that the amount of the Loan
exceeds the Maximum Loan Amount upon collection of the Collateral, the proceeds
of such Collateral shall be remitted to the Lender in reduction of the
Obligations;

          (b) not encumber, mortgage, pledge, assign or grant any security
interest in any of the Collateral to anyone other than the Lender;

          (c) keep and maintain the original and other documents evidencing, and
relating to, the agreements and transactions which gave rise to the Collateral,
including without limitation, all original orders and invoices;

          (d) perform all other steps reasonably requested by the Lender to
create and maintain in the Lender's favor a valid perfected security interest in
all of the Collateral; and

                                       4

<PAGE>

          (e) defend the Collateral against the claims and demands of all
parties.

time of each Credit Advance made hereunder), and covenants that:

other forms of payment or security that may come into the Lender's possession;

this Section or for any error of judgment or mistake of fact or law. This power,

unpaid and until the Obligations have been fully satisfied.

expenses, including, without limitation, reasonable fees and disbursements of

liable to the Lender for any deficiency.

     16. Waiver; Cumulative Remedies. Failure by the Lender to exercise any
right, remedy or option under this Agreement or any supplement hereto or any

will be effective unless it is in writing and then only to the extent
specifically stated. The Lender's rights and remedies under this Agreement will
be cumulative and not exclusive of any other right or remedy that the Lender may
have.

     17. Application of Payments. The Borrower irrevocably waives the right to
direct the application of any and all payments at any time or times hereafter
received by the Lender from or on the Borrower's behalf and the Borrower hereby
