                                    RECITALS

         Client and SHF are parties to that certain Financing Agreement dated as
of March 29, 2004, as amended (the "Agreement"). The parties desire to amend the
Agreement in accordance with the terms of this Amendment.

         NOW, THEREFORE, the parties agree as follows:

         1. The reference to "FIVE HUNDRED THOUSAND DOLLARS ($500,000) (the
'Credit Limit')" in Section 1.2 of the Agreement is hereby amended to read
"SEVEN HUNDRED AND FIFTY THOUSAND DOLLARS ($750,000) (the 'Credit Limit')".

         2. Client shall pay to SHF a commitment fee equal to $625.00 on the
date of the next Advance after the date of this Amendment, which fee shall be
fully earned and nonrefundable as of the date hereof. Client authorizes SHF to
deduct such fee from the proceeds of such Advance.

         3. Unless otherwise defined, all initially capitalized terms in this
Amendment shall be as defined in the Agreement. The Agreement, as amended
hereby, shall be and remain in full force and effect in accordance with its
respective terms and hereby is ratified and confirmed in all respects. Except as
expressly set forth herein, the execution, delivery, and performance of this
Amendment shall not operate as a waiver of, or as an amendment of, any right,
power, or remedy of SHF under the Agreement, as in effect prior to the date
hereof. Client ratifies and reaffirms the continuing effectiveness of all
guaranties, security agreements, mortgages, deeds of trust, environmental
agreements, and all other instruments, documents and agreements entered into in
connection with the Agreement.

         4. Client represents and warrants that the representations and
warranties contained in the Agreement are true and correct as of the date of
this Amendment, and that no Event of Default has occurred and is continuing.

         5. 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.

         6. As a condition to the effectiveness of this Amendment, SHF shall
have received, in form and substance satisfactory to SHF the following:
