     R.1. Seller, TH, EM, JE, FA and Buyer are parties to an Asset Purchase
Agreement, dated as of May 1, 2006 (together with the Exhibits and Schedules
thereto, the "APA"), pursuant to which Buyer purchased the Transferred Assets
from Seller on July 3, 2006 (the "Closing"). At the Closing, Buyer paid the $25
million Purchase Price for the Transferred Assets pursuant to the APA as
follows: (a) $5,000,000 by wire transfer to Seller and (b) by delivery of a $20
million subordinated convertible note to Seller in the form of APA Exhibit A
(the "Original Convertible Note"). (Capitalized terms used but not defined
herein shall have the meanings ascribed to them in the APA.)

     R.2. On or about April 1, 2007, as requested by Seller pursuant to APA
Section 5.20, ULB issued, as successor notes to the Original Convertible Note,
six subordinated convertible promissory notes in the aggregate principal amount
of $20 million (the "Convertible Notes"). The holders and principal amounts of
the Convertible Notes immediately prior to the effectiveness of this Agreement
are, respectively, as follows: (a) FA-$500,000; (b) JE-$1,000,000;
(c)TH-$4,625,000; (d) EM-$4,625,000; (e) GM-$4,625,000; and (f)LH-$4,625,000.

     R.3. In a letter dated June 27, 2007 from Buyer's counsel Arent Fox LLP to
Seller and Seller Shareholders, Buyer made claims against Seller and Seller
Shareholders, including for (a) the reimbursement of an overpayment made by
Buyer to Seller on or about January 16, 2007 pursuant to APA Section 2.6(c) and
(b) the reduction of the aggregate principal amount of the Convertible Notes as
indemnification under APA Section 8.1 for Buyer Losses that resulted from
breaches of the APA by Seller and each of FA, JE, TH and EM ("Seller
Shareholders"), as set forth in the letter from Buyer's counsel ("Buyer's Claim
Letter").

     R.4. In a letter dated July 6, 2007 from TH to ULB's representative Philip
A. Fain, Seller and Seller Shareholders protested Buyer's claims set forth in
Buyer's Claim Letter and claimed that Buyer owes Seller a specified additional
amount pursuant to APA Section 2.6 (c) ("Seller's Response Letter").

     R.5. The Parties desire to (a) settle, release and discharge in full all
claims set forth in the Buyer's Claim Letter and Seller's Response Letter and
(b) release and discharge in full any and all claims arising from
representations and warranties in the APA and certain other claims that might
otherwise arise pursuant to the APA.
