INTER ALIA, provided for a 45 day Exclusivity Period;

     B.   On May 12, 2005, Buyer and Seller entered into an amendment to the
Indemnification agreement which extended the Exclusivity Period until June 12,

     C.   Buyer and Seller desire to further extend the Exclusivity Period.

     NOW THEREFORE, for good and valuable consideration, the receipt and
