This Amendment No. 13 ("Amendment No. 13") is being filed jointly by Crestview
Capital Master, LLC ("Crestview") and Crestview Capital Partners, LLC
("Crestview Partners") (each, a "Reporting Person" and, collectively, the
"Reporting Persons") and amends the Schedule 13D filed by the Reporting Persons
on March 23, 2006, as amended by Amendment No. 1 thereto filed on March 23,
2006, as amended by Amendment No. 2 thereto filed on July 24, 2006, as amended

as amended by Amendment No. 12 thereto filed on May 4, 2007 (collectively, the
"Schedule 13D"). Except as set forth below, all Items of the Schedule 13D remain
unchanged. All capitalized terms not otherwise defined herein shall have the
meanings ascribed to such terms in the Schedule 13D.

ITEM 4. PURPOSE OF TRANSACTION

On May 14, the Reporting Persons informed the Issuer that they are prepared to
increase the cash portion of the contemplated purchase price for the Empagio
business to $15.2 million and that they remain ready to seek to mutually resolve
all other aspects of a transaction with the Reporting Persons as soon as
possible.

On May 10, an advisor to the Reporting Persons indicated to the Issuer that the
Reporting Persons might be prepared to pay a $15 million cash purchase price for
the business of Empagio. On May 11, the advisor indicated to the Issuer that the
Issuer would have to propose to the Reporting Persons the terms on which the
Issuer would be prepared to proceed with a transaction with the Reporting
Persons for the Empagio business and discussions and communication continued
through May 13. On May 12, counsel to the Reporting Persons produced a revised
draft of an asset purchase agreement for consideration of the parties. In an
effort to reach an agreement with the Issuer, the Reporting Persons indicated
that they were prepared to pay total consideration for the Empagio business of
$15 million in cash, together with the assumption by the acquired Empagio
business of the $2 million subordinated note of the Issuer to a Reporting
Person, subject to a working capital adjustment an escrow holdback, and various
other terms and conditions. Despite the efforts of the Reporting Persons, an
agreement was not reached and the Issuer informed a representative of the
Reporting Persons that the Issuer intends to proceed with an alternative
transaction. The Reporting Persons believe that no agreement was reached due to
the improper advantage that the Issuer provided to another bidder, Mr. Seth
Bernstein, and due to what the Reporting Persons believe were unrealistic,
improper and unfair negotiating demands of the Issuer and the unwillingness of
the Issuer to provide the Reporting Persons with a reasonable opportunity to
resolve such demands through discussions with representatives of the Issuer.
Accordingly, on the afternoon of May 13, Mr. Stewart Flink, a managing partner
of Crestview, wrote to the Issuer's Chief Executive Officer, Mr. Bienvenu,
expressing Mr. Flink's grave concern, including as one of the Issuer's largest
shareholders, as to how the Issuer handled the proposed transaction, and stating
that Mr. Flink viewed that action as typical of Mr. Bienvenu's tenure as CEO of
the Issuer. Mr. Flink stressed for Bienvenu the Issuer's intentional and
pre-meditated breach of its exclusivity obligation to the Reporting Persons and
that the Reporting Persons intend to monitor the Issuer carefully, especially
with respect to the terms and conditions of any transaction the Issuer is
ultimately able to consummate with respect to the business of Empagio,
especially in comparison to the demands made of the Reporting Persons as to such
a



transaction and the terms and conditions on which the Reporting Persons have
attempted to acquire the Empagio business. In this regard, the Reporting Persons
are gravely concerned that the terms and conditions upon which the Reporting
Persons have been prepared to proceed to acquire the business of Empagio,
particularly the terms and conditions set forth would both be superior for the
Issuer to the terms and conditions of any other offer received by the Issuer.
The Reporting Persons reserve the right to pursue all rights and remedies that
they have against the Issuer with respect to the breach of that April 17 letter
and otherwise. Likewise, the Reporting Persons reserve the right to pursue all
rights and remedies they may have against Mr. Bernstein, Chatham Capital, and
the Issuer's senior lender, Fortress Credit, including for (i) blatant
interference with the Reporting Person's dealings with the Issuer under the
April 17 Letter, a letter and dealings that were in full public view due to the
Reporting Person's prior 13D filings and/or (ii) improperly forcing the Issuer
to accept an alternative offer for the Empagio business. The Reporting Persons
have not decided how to otherwise proceed or what other specific actions to take
in light of the Issuer's actions. The Reporting Persons reserve all legal and
other rights and remedies available to them.
