on any invoice or bill of lading for any Account or drafts against account
debtors, (iii) make, settle, and adjust all claims under Borrower's insurance
policies; (iv) settle and adjust disputes and claims about the Accounts directly
with account debtors, for amounts and on terms Bank determines reasonable; and
(v) transfer the Collateral into the name of Bank or a third party as the Code
permits. Bank may exercise the power of attorney to sign Borrower's name on any
documents necessary to perfect or continue the perfection of any security
interest regardless of whether an Event of Default has occurred. Bank's
appointment as Borrower's attorney in fact, and all of Bank's rights and powers,
coupled with an interest, are irrevocable until all Obligations have been fully
repaid and performed and Bank's obligation to provide Credit Extensions
terminates.

9.3  Accounts Collection. When an Event of Default occurs and continues, Bank
     -------------------
may notify any Person owing Borrower money of Bank's security interest in the
funds and verify the amount of the Account. Borrower must collect all payments
in trust for Bank and, if requested by Bank, immediately deliver the payments to
Bank in the form received from the account debtor, with proper endorsements for
deposit.

9.4  Bank Expenses. If Borrower fails to pay any amount or furnish any required
     -------------
proof of payment to third persons Bank may make all or part of the payment or
obtain insurance policies required in Section 6.5, and take any action under the
policies Bank deems prudent. Any amounts paid by Bank are Bank Expenses and
immediately due and payable, bearing interest at the then applicable rate and
secured by the Collateral. No payments by Bank are deemed an agreement to make
similar payments in the future or Bank's waiver of any Event of Default.

9.5  Bank's Liability for Collateral. If Bank complies with reasonable banking
     -------------------------------
practices, it is not liable or responsible for: (a) the safekeeping of the
Collateral; (b) any loss or damage to the Collateral; (c) any diminution in the
value of the Collateral; or (d) any act or default of any carrier, warehouseman,
bailee, or other person. Borrower bears all risk of loss, damage or destruction
of the Collateral.

9.6  Remedies Cumulative. Bank's rights and remedies under this Agreement,
     -------------------
the Loan Documents, and all other agreements are cumulative. Bank has all rights
and remedies provided under the Code, by law, or in equity. Bank's exercise of
one right or remedy is not an election, and Bank's waiver of any Event of
Default is not a continuing waiver. Bank's delay is not a waiver, election, or
acquiescence. No waiver is effective unless signed by Bank and then is only
effective for the specific instance and purpose for which it was given.

9.7  Demand Waiver. Borrower waives demand, notice of default or dishonor,
     -------------
notice of payment and nonpayment, notice of any default, nonpayment at maturity,
release, compromise, settlement, extension, or renewal of accounts, documents,
instruments, chattel paper, and guaranties held by Bank on which Borrower is
liable.
