outstanding thereunder shall bear interest at the Applicable Interest Rate. The
amount and date of each Advance, and the amount and date of any repayment shall
be noted on Bank's records, which records will be conclusive evidence thereof
absent manifest error.

         2.4 Interest shall be payable on all Prime-based Advances, monthly, on
the first Business Day of each month. Interest shall be payable on each
Eurocurrency-based Advance on the last day of its Interest Period and, if such
Interest Period has a duration of longer than three (3) months, also at each
three month interval from the first day of such interest period.

         2.5 Borrower shall pay to Bank:

                  (a) concurrently with the execution of this Agreement, the
amount of the expenses (including without limit reasonable attorneys' fees,
whether of inside or outside counsel, and disbursements) incurred by the Bank in
connection with the preparation and closing of this Agreement and related
instruments and/or making of advances hereunder, including but not limited to
costs to conduct audits, monitoring and appraisals;

                  (b) concurrently with the execution of this Agreement, a
non-refundable closing fee in the amount of Seventy Five Thousand Dollars
($75,000);

                  (c) on an ongoing basis, (i) all audit costs, limited to
four (4) audits per annum, in the amount of $750 per day per auditor and (ii)
collateral monitoring costs of Bank in the amount of $500 per month, with
such audit and monitoring costs subject to periodic increases by Bank as are
usual and customary in connection with the Bank's cost of doing business.

                  Borrower shall pay all inventory appraisal fees directly to
such appraiser(s).

         2.6 The amount of all interest and fees hereunder shall be computed for
the actual number of days elapsed on the basis of a year consisting of three
hundred sixty (360) days.

         2.7 Any payment of the Indebtedness made by mail will be deemed
tendered and received only upon actual receipt by the Bank at the address
designated for such payment, whether or not the Bank has authorized payment by
mail or any other manner, and shall not be deemed to have been made in a timely
manner unless received on the date due for such payment, time being of the
essence. The Borrower expressly assumes all risks of loss or liability resulting

                                      -10-
<PAGE>

from non-delivery or delay of delivery of any item of payment transmitted by
mail or in any other manner. Acceptance by the Bank of any payment in an amount
less than the amount then due shall be deemed an acceptance on account only.

         2.8 Notwithstanding anything herein to the contrary, in the event and
so long as an Event of Default shall exist, all principal outstanding under the
Note shall bear interest, payable on demand, from the date of such Event of
Default at a rate per annum equal to:

                  (a) in the case of a Prime-based Loan, two and one half
percent (2.5%) above the Prime-base Rate; and

                  (b) in the case of a Eurocurrency-based Loan, two and one
half percent (2.5%) above the Eurocurrency-based Rate until the end of the
then current Interest Period, at which time such Eurocurrency-based Loans
shall be automatically converted into Prime-based Loans and bear interest at
the rate provided for in clause (a) above.

         2.9 Providing that no Event of Default shall have occurred and be
continuing, the Borrower may elect to renew or convert Applicable Interest Rates
applicable to Advances from the Prime-based Rate to the Eurocurrency-based Rate
or from the Eurocurrency-based Rate to the Prime-based Rate, provided that any
conversion of a Eurocurrency-based Loan shall be made only on the last Business
Day of the Interest Period applicable to such Eurocurrency-based Loan. If the
Borrower desires such a renewal or conversion, it shall give Bank not less than
three (3) Business Days' prior notice in the manner provided in Section 2.2
hereof, specifying the date of such renewal or conversion, the Advances to be
converted and the type of Advances elected. If with respect to any
Eurocurrency-based Loan outstanding at any time the Bank does not receive notice
of the election from a Borrower not less than three (3) Business Days prior to
the last day of the Interest Period therefor, the Borrower shall be deemed to
have elected to convert such Eurocurrency-based Loan to a Prime-based Loan at
the end of the then current Interest Period unless such Eurocurrency-based Loan
is repaid upon the last day of such Interest Period.

         2.10 In the event that Borrower shall terminate this Agreement on or
before the Maturity Date, Borrower shall be obligated to pay to Bank, as a
condition to such termination and prior to the release of Bank's liens and
encumbrances, the amount of: (a) Four Hundred Thousand Dollars ($400,000) if
such termination occurs before the first anniversary hereof; or (b) Two Hundred
Thousand Dollars ($200,000) if such termination occurs on or after the first
anniversary hereof but before the second anniversary of this Agreement. This
Early Termination Compensation shall be waived if the Loan is replaced by
another credit facility with Bank.

         2.11 If the Equivalent Amount of Advances outstanding under the Loan
exceeds the Facility Maximum, then Borrower shall immediately repay Advances by
the amount necessary so that, after payment, the Equivalent Amount of Advances
shall not be greater than the Facility Maximum.

3. SPECIAL PROVISIONS FOR EUROCURRENCY-BASED LOANS

         3.1 As to any Advances, if any prepayment thereof shall occur on any
day other than the last day of an Interest Period (in the case of a
Eurocurrency-based Loan) or the first day of an Interest Period (with regard to
a Prime-Based Loan) (whether pursuant to this Article, or by

                                      -11-
<PAGE>

acceleration, or otherwise), or if an Applicable Interest Rate shall be changed
during any Interest Period pursuant to this Article, the Borrower agrees to
reimburse Bank any costs incurred by Bank as a result of the timing thereof
including but not limited to any net costs incurred in liquidating or employing
deposits from third parties, upon Bank's delivery to Borrower of a certificate
setting forth in reasonable detail the basis for determining such costs, which
certificate shall be conclusively presumed correct save for manifest error.

         3.2 For any Advance for which the Applicable Interest Rate is the
Eurocurrency-based Rate, if Bank shall designate a Eurocurrency lending office
which maintains books separate from those of the rest of Bank, Bank shall have
the option of maintaining and carrying the relevant advance on the books of such
office.

         3.3 If Bank determines that, by reason of circumstances affecting the
foreign exchange and interbank markets generally, deposits in Eurocurrencys in
the applicable amounts are not being offered to Bank for an Interest Period,
then Bank shall forthwith give notice thereof to the Borrower. Thereafter, the
obligation of Bank to make Eurocurrency-based Loans, and the right of Borrower
to convert an Advance to or refund an Advance as a Eurocurrency-based Loan shall
be suspended and all subsequent Loans, and renewals and conversions of then
outstanding Loans shall be Prime-based Loans bearing interest at the Prime-based
Rate until the Bank notifies Borrower that such circumstance no longer exists.

         3.4 If, after the date hereof, the introduction of, or any change in,
any applicable law, rule or regulation or in the interpretation or
administration thereof by any governmental authority charged with the
interpretation or administration thereof, or compliance by Bank (or its
Eurocurrency lending offices) with any request or directive (whether or not
having the force of law) of any such authority, shall make it unlawful or
impossible for Bank to honor its obligations hereunder to make or maintain any
Advance with interest at the Eurocurrency-based Rate, Bank shall forthwith give
notice thereof to Borrower. Thereafter: (a) the obligations to make
Eurocurrency-based Loans and the right of Borrower to convert an Advance or
refund an Advance as a Eurocurrency-based Loan shall be suspended; and (b) if
Bank may not lawfully continue to maintain a Eurocurrency-based Loan to the end
of the then current Interest Period, the Prime-based Rate shall be the
Applicable Interest Rate for such Eurocurrency-based Loan for the remainder of
such Interest Period.

         3.5 In the event that any change after the date hereof in applicable
law, treaty or governmental regulation, or in the interpretation or application
thereof, or compliance by Bank with any request or directive (whether or not
having the force of law) from any central bank or other financial, monetary or
other authority:

                  (a) shall subject Bank (or its Eurocurrency lending office)
to any tax, duty or other charge with respect to any Advance or shall change
the basis of taxation of payments to Bank (or its Eurocurrency lending
office) of the principal of or interest on any Advance or any other amounts
due under this Agreement (except for changes in the rate of tax on the
overall net income or gross receipts of Bank or its Eurocurrency lending
office imposed by the jurisdiction in which Bank's principal executive office
or Eurocurrency lending office is located); or

                                      -12-
<PAGE>

                  (b) shall impose, modify or deem applicable any reserve
(including, without limitation, any imposed by the Board of Governors of the
Federal Reserve System but excluding with respect to any Eurocurrency-based
Loan any such requirement included in an applicable Eurocurrency Reserve
Requirement), special deposit, or similar requirement against assets of,
deposits with or for the account of, or credit extended by Bank (or its
Eurocurrency lending offices) or shall impose on Bank (or its Eurocurrency
lending offices) or the foreign exchange and interbank markets or other
condition affecting any Advance or any commitment of Bank under this
Agreement; and the result of any of the foregoing is to increase the cost to
Bank of making, renewing or maintaining any Advance or its commitments
hereunder or to reduce the amount or rate of return on any sum received or
receivable by Bank under this Agreement, or under any Note, then Bank may
promptly notify Borrower of such fact and demand compensation therefor and
Borrower agrees to pay to Bank (so long as such event or circumstance
continues to exist) such additional amount or amounts as will compensate Bank
for such increased costs or reduced return within thirty (30) days of such
notice; provided, however that, to the extent doing so would eliminate or
decrease Borrower's liability for increased costs hereunder, and to the
extent that doing so would not otherwise be disadvantageous to Bank, Bank
will attempt to designate a Eurocurrency lending office for which the tax,
duty, reserve, deposit requirement, or other circumstance giving rise to
Bank's demand for increased compensation, is not applicable. A certificate of
the Bank demanding such compensation setting forth in reasonable detail the
basis for determining such additional amount or amounts necessary to
compensate shall be conclusively presumed to be correct save for manifest
error.

         3.6 At no time shall there be greater than three (3) outstanding
Advances on a Eurocurrency-based Loan.

         5.2 The execution, delivery and performance of this Agreement, and any
other documents and instruments required under this Agreement, and the issuance

outcome of which if determined adversely would materially impair the financial

case (A) asserts or alleges that Borrower violated Environmental Laws, (B)
asserts or alleges that Borrower is required to clean up, remove, or take
remedial or other response action due to the disposal, depositing, discharge,

                                      -15-
<PAGE>

discharge, making or other release of any hazardous substances or materials by
Borrower.

         5.8 There are no conditions existing currently or likely to exist

Environmental Laws or which require or are likely to require material cleanup,

reviewing its major commercial counterparts with a view to assessing whether it
will, in the receipt, transmission, processing, manipulation, storage,
retrieval, retransmission or other utilization of data, be vulnerable to a Year
2000 Issue. Based on such review, Borrower has no reason to believe that any
Material Adverse Effect will occur with respect to its businesses or operations
resulting from a Year 2000 Issue.

         On a continuing basis from the date of this Agreement until the

casualty insurance, made payable to the Bank. If the Borrower fails to maintain
satisfactory insurance as herein provided, the Bank shall have the option to do
so, and the Borrower agrees to repay the Bank upon demand, with interest at the
Prime-based Rate then in effect for the Revolving, all amounts so expended by
the Bank. The Borrower hereby appoints the Bank or any employee or agent of the

fail to pay such taxes and assessments within the time they can be paid without
penalty, late charge or interest the Bank shall have the option to do so, and
the Borrower agrees to repay the Bank upon demand, with interest at the
Prime-based Rate from time to time in effect under the Note, all amounts so

an Event of Default of the type described in Section 8.1.(f) above, and upon
written notice from Bank in the case of any other Event of Default) without
presentation, demand, protest, notice of dishonor or other further notice of any
kind, all of which are hereby expressly waived, and Bank shall have no further
commitment to make Advances. Unless all of the Indebtedness is then immediately
fully paid, the Bank shall have and may exercise any one or more of the rights
and remedies for which

                                      -22-
<PAGE>

provision is made for a secured party under the UCC, under the or for which
provision is provided by law or in equity, including, without limitation, the
right to take possession and sell, lease or otherwise dispose of any or all of
the Collateral and to set off against the Indebtedness any amount owing by the
Bank to the Borrower and/or any property of the Borrower in possession of the
Bank. The Borrower agrees, upon request of the Bank, to assemble the Collateral
and make it available to the Bank at any place designated by the Bank.

         8.3 All of the Indebtedness shall constitute one loan secured by the
Bank's security interest in the Collateral and by all other security interests,
mortgages, liens, claims, and encumbrances now and from time to time hereafter
granted from the Borrower to the Bank. Upon the occurrence of an Event of
Default which is not cured within the cure period, if any, provided under
Section 8.1, the Bank may in its sole discretion apply the Collateral to any
portion of the Indebtedness. The proceeds of any sale or other disposition of
the Collateral authorized by this Agreement shall be applied by the Bank, first
upon all expenses authorized by the UCC or otherwise in connection with the sale
and all reasonable attorneys' fees and legal expenses incurred by the Bank, the
balance of the proceeds of such sale or other disposition shall be applied in
the payment of the Indebtedness, first to interest, then to principal, then to
other Indebtedness and the surplus, if any, shall be paid over to the Borrower
or to such other Person or Persons as may be entitled thereto under applicable
law. The Borrower shall remain liable for any deficiency, which the Borrower
shall pay to the Bank immediately upon demand.

         8.4 The remedies provided for herein are cumulative to the remedies for
collection of the Indebtedness as provided by law, in equity or by any Loan
Document. Nothing herein contained is intended, nor shall it be construed, to
preclude the Bank from pursuing any other remedy for the recovery of any other
sum to which the Bank may be or become entitled for the breach of this Agreement
by the Borrower.

9. MISCELLANEOUS

         9.1 This Agreement shall be binding upon and shall inure to the benefit
of Borrowers and Bank and their respective successors and assigns, except that
the credit provided for under this Agreement and no part thereof and no
obligation of Bank hereunder shall be assignable or otherwise transferable by
Borrowers.

         9.2 Where the character or amount of any asset or liability or item of
income or expense is required to be determined or any other accounting
computation is required to be made for the purposes of this Agreement, unless
the calculation of such item, amount or computation is specifically defined to
the contrary herein, it shall be done in accordance with GAAP.

         9.3 No delay or failure of Bank in exercising any right, power or
privilege hereunder shall affect such right, power or privilege, nor shall any
single or partial exercise thereof preclude any further exercise thereof, or the
exercise of any other power, right or privilege. The rights of Bank under this
Agreement are cumulative and not exclusive of any right or remedies which Bank
would otherwise have.

         9.4 Until Borrowers or Bank, as the case may be, shall notify one
another in writing that notices shall be sent to some other address, in which

         All agreements between the Borrowers and the Bank pertaining to the
indebtedness described herein are expressly limited so that in no event
whatsoever shall the amount of interest paid or agreed to be paid to the Bank
exceed the highest rate of interest permissible under applicable law. If, from
any circumstances whatsoever, fulfillment of any provision of this Agreement,
the Loan Documents, the Note(s) or any other instrument securing the Note(s) or
all or any part of the indebtedness secured thereby, at the time performance of
such provision shall be due, shall involve exceeding the interest limitation
validly prescribed by law which a court of competent jurisdiction may deem
applicable thereto, then, the obligation to be fulfilled shall be reduced to an
amount computed at the highest rate of interest permissible under such
applicable law, and if, for any reason whatsoever, the Bank shall ever receive
as interest an amount which would be deemed unlawful under such applicable law,
such interest shall be automatically applied to the payment of the principal
amount described herein or otherwise owed by the relevant Borrowers to Bank
(whether or not then due and payable) and not to payment of interest.

costs, liabilities and expenses (including but not limited to reasonable
investigation, environmental audit(s), and legal expenses) arising out of any
claim, loss or damage of any property, injuries to or death of persons,
contamination of or adverse affects on the environment, or any violation of any
applicable Environmental Laws, caused by or in any way related to the real
property owned by Borrowers, or due to any acts of Borrowers, its officers,
directors, shareholders, employees, consultants and/or representatives. In no
event shall the Borrowers be liable hereunder for any loss, damages, suits,
penalties, costs,

misconduct of Bank, or its agents or employees.

         9.7 It is expressly understood and agreed that the indemnifications
granted herein are intended to protect Bank, its past, present and future
officers, directors, shareholders, employees, consultants and representatives
from any claims that may arise by reason of the security interest, liens and/or
mortgages granted to Bank, or under any other document or agreement given to
secure repayment of any indebtedness from Borrowers, whether or not such claims
arise before or after Bank has foreclosed upon and/or otherwise become the owner
of any such property. All obligations of indemnity as provided hereunder shall
be secured by the Loan Documents.

         9.8 It is expressly agreed and understood that the provisions hereof
shall and are intended to be continuing and shall survive the repayment of any
indebtedness from Borrowers to the Bank.

is a constitutional one, but that it may be waived, and, after consulting with
counsel of their choice, knowingly and voluntarily, and for their mutual

the performance or enforcement of, or in any way related hereto.
