(e) Exhibit C to the Loan Agreement is amended to read as provided in Attachment A
hereto.



2. NO DEFENSES OF BORROWER. Borrower agrees
that, as of the date hereof, it has no defenses against paying any of the Obligations.



3. CONDITIONS. The effectiveness of this Amendment is conditioned upon:



(a) Borrowers payment to Bank of a restructuring fee of $3,500; and



(b) payment of all Bank Expenses relating to this Amendment.



5. CONTINUING VALIDITY. Borrower understands and agrees that in
modifying the existing Obligations and Loan Agreement hereunder, Bank is relying upon Borrowers representations, warranties, and agreements, as set forth in the Loan Documents as modified by this Amendment. Except as expressly modified
pursuant to this Amendment, the terms of the Loan Documents remain unchanged and in full force and effect. Banks agreement to modifications to the existing Obligations pursuant to this Amendment in no way shall obligate Bank to make any future
modifications to the Obligations. Nothing in this Amendment shall constitute a satisfaction of the Obligations. It is the intention of Bank and Borrower to retain as liable parties all makers and endorsers of Loan Documents as in effect prior to the
effectiveness of this Amendment, unless the party is expressly released by Bank in writing. Unless expressly released herein, 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 agreements.



6. COUNTERPARTS. This Amendment may be signed in any number of counterparts, and by different parties in separate counterparts, with the same effect as if the signatures to each such counterpart were upon a
single instrument. All counterparts shall be deemed an original of this Amendment.



This Amendment is executed as of the date first written above.
