Ladies and Gentlemen:

This letter agreement confirms the additional agreements between the Borrower

agreements set forth herein, and for other good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged by the parties, the

Borrower's request, the Bank shall make loans to the Borrower during the period

not exceeding $1,700,000.00 at any time outstanding (the "Line of Credit"). The
Line of Credit is a revolving line of credit, and the Borrower may borrow,
prepay and re-borrow under the Line of Credit. The Borrower's obligation to
repay such loans and to pay interest and other charges, fees and expenses
thereon is evidenced by the Borrower's promissory note dated April 30, 1999

called the "Revolving Note"). The Bank may credit each such loan to the
Borrower's account number 2510497693 at the Bank. The Bank shall have no
obligation to make any such loan after the occurrence of any Event of Default.
In each period of 12 months ending on April 30 of each year, the Borrower shall
cause the unpaid principal balance of the Revolving Note to be zero for 30
consecutive days. The Borrower shall use all proceeds of such loans solely for
working capital purposes.

principal balance of the Revolving Note to exceed the Borrowing Base.

___________, the Bank shall make one or more loans to the Borrower in an
aggregate amount not exceeding __________ (collectively called the "Term Loan").

thereon is evidenced by the Borrower's promissory note dated ____________
payable to the order of the Bank in the principal amount of ____________
(together with any amendments, extensions, renewals and replacements thereof,
called the "Term Note"). The Bank may credit each such loan to the Borrower's
account number __________ at the Bank. The Bank shall have no obligation to make
