This letter serves as request and authorization for you to remove the Closing Reserve and, provided that no Event of Default under the Loan Agreement has occurred and is continuing, make an Advance in the Closing Reserve Amount to the parties and in the amounts set forth below, and to charge Borrower's account therefor:
