III.   Legal Effect.

  A.   The Agreement is hereby amended wherever necessary to reflect the changes
described above. Borrower agrees that it has no defenses against the obligations
to pay any amounts under the Indebtedness.     B.   Borrower understands and
agrees that in modifying the existing Indebtedness, Bank is relying upon
Borrower’s representations, warranties, and agreements, as set forth in the
Agreement. Except as expressly modified pursuant to this Amendment, the terms of
the Agreement remain unchanged, and in full force and effect. Bank’s agreement
to modifications to the existing Indebtedness pursuant to this Amendment in no
way shall obligate Bank to make any future modifications to the Indebtedness.
Nothing in this Amendment shall constitute a satisfaction of the Indebtedness.
It is the intention of Bank and Borrower to retain as liable parties, all makers
and endorsers of Agreement, unless the party is expressly released by Bank in
writing. No maker, endorser, or guarantor will be released by virtue of this
Amendment. The terms of this paragraph apply not only to this Amendment, but
also to all subsequent loan modification requests.     C.   This Amendment may
be executed in two or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one instrument. This is an
integrated Amendment and supersedes all prior negotiations and agreements
regarding the subject matter hereof. All modifications hereto must be in writing
and signed by the parties.

IV.   Conditions Precedent. Except as specifically set forth in this Amendment,
all of the terms and conditions of the Agreement remain in full force and
effect. The effectiveness of this Agreement is conditioned upon receipt by Bank
of this Amendment, and any other documents which Bank may require to carry out
the terms hereof, including but not limited to the following:

  A.   This Amendment, duly executed by Borrower; and     B.   Such other
documents, and completion of such other matters, as Bank may reasonably deem
necessary or appropriate.

IN WITNESS WHEREOF, the undersigned have executed this Amendment as of the first
date above written.
