pay the Reimbursement Amount pursuant to the Letter of Credit Agreement and
fails to pay the Reimbursement Amount and interest thereon within five (5) days

the Agreement to request Advances. Such person or persons are hereby authorized
by BORROWER to request Letters of Credit and Advances, to execute and deliver
Letter of Credit Agreements on behalf of BORROWER , and to direct disposition of
the proceeds of Advances until written notice of the revocation of such

time exceeds the lesser of (A) and (B), BORROWER , without notice or demand,
shall immediately make a payment to BANK in an amount equal to the sum of (1)
such excess and (2) accrued and unpaid interest thereon.

18. Collateral Upon Event of Default. Upon an event of default and demand by
BANK in its absolute and sole discretion, BORROWER shall immediately deliver to
BANK, as security for all obligations of Borrower under the Loan Documents
(including, without limitation, the obligation to pay Reimbursement Amounts),
immediately available funds in an amount equal to the sum of (i) the aggregate

amount of outstanding and unpaid drafts drawn or drawn and accepted under
Letters of Credit. BORROWER hereby grants to BANK a security interest in all
such funds delivered to BANK to secure payment and performance of said
obligations.

19. Conditions Precedent to Each Advance and Letter of Credit. BANK shall be
obligated to issue a Letter of Credit or make an Advance when requested by
BORROWER only if the representations and warranties by the Loan Parties in the
Loan Documents are accurate on and as of the date of this Agreement and on and
as of the date of issuance of the Letter of Credit or of making the Advance
before and after giving effect to the Letter of Credit or the Advance and the
application of the proceeds of the Advance. Delay or failure by BANK to insist
on satisfaction of any condition of issuance of a Letter of Credit or making an
Advance shall not be a waiver of such condition precedent or any other condition
precedent. If BORROWER is unable to satisfy any condition precedent of issuance
of a Letter of Credit or making an Advance, the issuance of the Letter of Credit
or the making of the Advance shall not preclude BANK from thereafter declaring
the condition or event causing such inability to be an event of default.
