     uses for such increase. The Agent may, in the exercise of its sole
     discretion, approve or disapprove of the Borrower's request. If the Agent
     shall approve, no Lender shall have any obligation, express or implied, to
     offer to increase its Commitment. Only the consent of the Agent and those
     Lenders that have increased their Commitments (the "Increasing Lenders")
     shall be required for an increase in the Commitment Amounts pursuant to
