Purchasers hereby waive any and all defaults by the Company under the Purchase
Agreement and any other certificate, agreement, document or other instrument
relating to the Purchase Agreement (collectively, the “Related Agreements”) in

consideration for this waiver, the face value of the Term Note issued to Shelter
Island in the Purchase Agreement shall be amended and increased to $840,000, and
the face value of the Term Note issued to Topwater in the Purchase Agreement

any contracts between the parties, any and all amounts due and payable under the
Purchase Agreement and the Related Agreements, including the amended Term Notes,
shall be due on or before February 8, 2007.

This letter may be executed in any number of counterparts, each of which shall
be deemed to be an original as against any party whose signature appears
