“Borrower acknowledges that it previously has entered, and/or may in the future enter, into Bank Services Agreements with Bank.  Regardless of the terms of any Bank Services Agreement, Borrower agrees that any amounts Borrower owes Bank thereunder shall be deemed to be Obligations hereunder and that it is the intent of Borrower and Bank to have all such Obligations secured by the first priority perfected security interest in the Collateral granted herein (subject only to Permitted Liens that expressly have superior priority to Bank’s Lien in this Agreement).

and inserting in lieu thereof the following:

“(1)                           During a Streamline Period, provided a Quarterly Advance Period is not in effect, Bank shall deposit such proceeds into Borrower’s operating account at Bank, provided no Default or an Event of Default has occurred and is continuing.  At all other times, Bank shall apply such proceeds to the outstanding Advances, and if all outstanding Advances have been paid in full, Bank shall deposit the remainder into Borrower’s operating account at Bank; and”
