                             REMEDIES ON DEFAULT

by law:

payable.

an amount equal to the then existing Letter of Credit Obligations.

extending credit to or for the account of the Borrower under this Agreement or
under any other agreement now existing or hereafter entered into between the
Borrower and the Bank.

Bank without affecting the Borrower's obligations to the Bank or the Bank's
rights and remedies under this Agreement or under any other document,
instrument or agreement.

11.5 Protection of Security Interest: Make such payments and do such acts as the
Bank, in its sole judgment, considers necessary and reasonable to protect its
security interest or lien in the Collateral. The Borrower hereby irrevocably
authorizes the Bank to pay, purchase, contest or compromise any encumbrance,
lien or claim which the Bank, in its sole judgment, deems to be prior or
superior to its security interest. Further, the Borrower hereby agrees to pay to
the Bank, upon demand therefor, all expenses and expenditures (including
attorneys' fees) incurred in connection with the foregoing.

11.6 Foreclosure: Enforce any security interest or lien given or provided for
under this Agreement or under any security agreement, mortgage, deed of trust or

judgment, deems to be necessary or appropriate and the Borrower hereby waives
any and all rights, obligations or defenses now or hereafter established by law
relating to the foregoing. In the enforcement of its security interest or lien,
the Bank is authorized to enter upon the premises where any Collateral is
located and take possession of the Collateral or any part thereof, together with
the Borrower's records pertaining thereto, or the Bank may require the Borrower
to assemble the Collateral and records pertaining thereto and make such
Collateral and records available to the Bank (including a copy of the Borrower's
customer lists) at a place designated by the Bank. The Bank may sell the
Collateral or any portions thereof, together with all additions, accessions and
accessories thereto, giving only such notices and following only such procedures
as are required by law, at either a public or private sale, or both, with or
without having the Collateral present at the time of the sale, which sale shall
be on such terms and conditions and conducted in such manner as the Bank
determines in its sole judgment to be commercially reasonable. Any deficiency
which exists after the disposition or liquidation of the Collateral shall be a
continuing liability of the Borrower to the Bank and shall be immediately paid
by the Borrower to the Bank.

11.7 Non-Exclusivity of Remedies: Exercise one or more of the Bank's rights set
forth herein or seek such other rights or pursue such other remedies as may be
provided by law, in equity or in any other agreement now existing or hereafter
entered into between the Borrower and the Bank, or otherwise.

11.8 Application of Proceeds: All amounts received by the Bank as proceeds from
the disposition or liquidation of the Collateral shall be applied to the
Borrower's indebtedness to the Bank as follows: first, to the costs and
expenses of collection, enforcement, protection and preservation of the Bank's
lien in the Collateral,

                                       11

 
including court costs and reasonable attorneys' fees, whether or not suit is
commenced by the Bank; next, to those costs and expenses incurred by the Bank
in protecting, preserving, enforcing, collecting, liquidating, selling or
disposing of the Collateral; next, to the payment of accrued and unpaid
interest on all of the Obligations; next, to the payment of the outstanding
principal balance of the Obligations; and last, to the payment of any other
indebtedness owed by the Borrower to the Bank. Any excess Collateral or excess
proceeds existing after the disposition or liquidation of the Collateral and
after the expiration of all outstanding Letters of Credit will be returned or
paid by the Bank to the Borrower.

                                 SECTION 12
                                MISCELLANEOUS

12.1 Amounts Payable on Demand: If the Borrower shall fall to pay on demand any
amount so payable under this Agreement (including but not limited to interest),
the Bank may, at its option and without any obligation to do so and without
waiving any default occasioned by the Borrower having so failed to pay such
amount, create an Advance under the Line of Credit in an amount equal to the
amount so payable, which Advance shall thereafter bear interest as provided
under the Line of Credit.

12.2 Reliance: Each warranty, representation, covenant, obligation and agreement
contained in this Agreement shall be conclusively presumed to have been relied
upon by the Bank regardless of any investigation made or information possessed
by the Bank and shall be cumulative and in addition to any other warranties,
representations, covenants and agreements which the Borrower now or hereafter
shall give, or cause to be given, to the Bank.

12.3 Attorneys' Fees: In the event of any dispute or legal action in relation to
this Agreement or any document, instrument or agreement executed with respect

all other sums to which it may be entitled, be entitled to reasonable attorneys'
fees.
