         and enforced under the Securities Purchase Agreement, as amended,
         subject in all respects to such amendments, modifications, and
         supplements and all terms and conditions of this 1997 Amendment.
         Initially capitalized terms used in this 1997 Amendment shall have the
         meanings ascribed thereto in the Securities Purchase Agreement, as
         amended hereby, unless otherwise defined herein.

         4.2. Ratification of the Agreement. Except as expressly set forth in
         this 1997 Amendment, all agreements, covenants, undertakings,
         provisions, stipulations, and promises contained in the Agreement and
         the Securities are hereby ratified, re-adopted, approved, and confirmed
         and remain in full force and effect.

         4.3. No Implied Waiver.  The execution, delivery and performance of
         this 1997 Amendment shall not, except as expressly provided herein,
         constitute a waiver or modification of any provision of, or operate as
         a waiver of any right, power or remedy of the Purchaser under the
         Securities Purchase Agreement or prejudice any right or remedy that
         the Purchaser may have or may have in the future under or in
         connection with the Securities Purchase Agreement or any instrument or
         agreement referred to therein. The Corporation acknowledges and agrees

         Amendment shall be governed by, and construed and enforced in

         executed in counterparts, each of which shall be deemed to be an
         original, but all of which together shall constitute one and the same
         instrument. Delivery of an executed counterpart of this 1997 Amendment
         by facsimile shall be equally as effective as delivery of a manually
         executed counterpart. Any party delivering an executed counterpart of
         this 1997 Amendment by facsimile shall also deliver a manually executed
         counterpart, but the failure to deliver a manually executed counterpart
         shall not affect the validity, enforceability, and binding effect of
         this 1997 Amendment.

         IN WITNESS WHEREOF, the undersigned have caused this 1997 Amendment to
be executed by their duly authorized officers as of the date first written
above.
