   security agreements and mortgages shall be and remain in full force and
   effect and that any rights and remedies of the Agent thereunder,
   obligations of such Borrower thereunder and any liens and security
   interests created or provided for thereunder shall be and remain in full

             This Amendment maybe executed in any number of counterparts and
   by different parties hereto on separate counterpart signature pages, each
   of which when so executed shall be an original but all of which shall
   constitute one and the same instrument.  Except as specifically amended,
   modified and waived hereby, all of the terms and conditions of the Credit
   Agreement in any document shall be deemed to be references to the Credit
   Agreement, as amended hereby.  All capitalized terms used herein without
   definition shall have the same meaning herein as they have in the Credit
   Agreement.
