Guaranty, pursuant to a Senior Note and Warrant Purchase Agreement dated as of
the date hereof (as amended, modified, restated or otherwise supplemented from
time to time, the "Purchase Agreement") Borrower is issuing certain Senior
Secured Promissory Notes (the "Notes") to the Purchasers identified in the
Purchase Agreement; and

            WHEREAS, it is a condition precedent to the purchasing of the Notes
that Guarantor shall have executed a guaranty for the benefit of those
Purchasers and their successors, heirs and assigns (collectively "Noteholders");
and

            WHEREAS, simultaneously with the issuance of the notes, Borrower is
issuing certain other notes ("Other Notes") that have payment terms and

Obligations have been indefeasibly paid in full.
