(b)     Borrowing and Repayment. Borrower may from time to time during the term of the Line of Credit borrow, partially or wholly repay its outstanding borrowings, and reborrow, subject to all of the limitations, terms and conditions contained herein or in the Line of Credit Note; provided however, that the total outstanding borrowings under the Line of Credit shall not at any time exceed the maximum principal amount available thereunder, as set forth above."
