and warranties of Borrower set forth herein and in the other Loan Documents, Secured Party agrees to make such Loans at such times
as Borrower may from time to time request, and in such amounts as Borrower may from time to time request, provided, however, that
the aggregate principal balance of all Loans outstanding at any time shall not exceed the Loan Availability. Loans made by Secured

Date unless the Loans are otherwise accelerated, terminated or extended as provided in this Security Agreement. The Loans shall

ii.	Loan

outstanding from time to time shall be due and payable monthly on the first day of each calendar month. Lender shall have the right

iii.	Loan
Principal Payments. All Loans hereunder shall be repaid by Borrower on the Loan Maturity Date, unless payable sooner pursuant
to the provisions of this Agreement. In the event the aggregate outstanding principal balance of all Loans hereunder exceeds the
Loan Availability, Borrower shall, without notice or demand of any kind, immediately, make such repayments of the Loans or take

or under the Note shall become due on a day other than a Business Day, such payment shall be made on the next succeeding Business
Day and such extension of time shall be included in computing any interest in respect of such payment. Notwithstanding anything
to the contrary contained herein, the final payment due under any of the Loans must be made by wire transfer or other immediately
available funds. All payments made by Borrower hereunder or under any of the Loan Documents shall be made without setoff, counterclaim,
or other defense. To the extent permitted by applicable law, all payments hereunder or under any of the Loan Documents (including
any payment of principal, interest, or fees) to, or for the benefit, of any Person shall be made by Borrower free and clear of,
and without deduction or withholding for, or account of, any taxes now or hereinafter imposed by any taxing authority.
