Loans
for additional sums requested by the Borrower may be made at the Lender's sole discretion based upon the Lender's valuation of the Borrower's collateral or other factors. The
Borrower acknowledges and agrees that the Lender may from time to time, for the Lender's convenience, segregate or apportion the Borrower's collateral for purposes of determining the amounts and

maximum amounts of Advances which may be made hereunder. Nevertheless, the Lender's security interest in all such collateral, and any other collateral rights, interests and properties which may now or
hereafter be available to the Lender, shall secure and may be applied to the payment of any and all Advances and other indebtedness secured by the Lender's security interest, in any order or manner of
application and without regard to the method by which the Lender determines to make Advances hereunder.

shall pay to the Lender an annual fee in an amount equal to one percent (1%) of the maximum aggregate amount of the letters of credit ($4,100) (the "Letter of Credit Fee"). The initial Letter of
