     Lender agrees to make loans to Borrower on a revolving basis (such
     loans being herein called individually, a "Revolving Loan", and
     collectively, the "Revolving Loans") from time to time in such amounts
     as Borrower may from time to time request up to an aggregate amount
     outstanding of $10,000,000.00; provided, however, that (i) each
     borrowing by Borrower hereunder with respect to any Revolving Loan
     shall be in the aggregate principal amount of at least $10,000.00;
     (ii) the Lender's commitment to make Revolving Loans shall remain in
     effect for a period to and including November 1, 2002 (the "Revolver
     Termination Date"); (iii)

     repay to the Lender all Revolving Loans, plus interest accrued to the date
     of payment; and (iv) for a period of at least 30 consecutive days during
     each fiscal year of Borrower, the amount of Revolving Loans outstanding
     shall not exceed $2,000,000.00.

     4.   Borrower shall deliver to Lender as a condition to Lender's
undertakings as provided hereunder, note amendments, a copy of its Articles of
Incorporation certified by the Delaware Secretary of State, a directors'
consent, secretary's certificate and such other documents as Lender shall
request, each in form and substance satisfactory to Lender and its counsel.
