Gentlemen:
This will confirm our understanding that the Cornell Agreement is amended as
follows:

  1.   The automatic termination date of November 7, 2007, set forth in the last
sentence of paragraph 1 of the Cornell Agreement, is hereby changed to
December 15, 2007.     2.   Upon the Effective Date, the “Conversion Shares
Reservation” as set forth in paragraph 7 (G) of the Cornell Agreement is hereby
reduced from 10 million shares to 8.75 million shares (which amount shall not
include any shares issued prior to the Effective Date). References to the
“Conversion Shares Reservation” in Section 8 of the Cornell Agreement shall
hereinafter refer to 8.75 million shares.     3.   In addition to the
conversions previously permitted under paragraph 11 of the Cornell Agreement,
from and after the effective date of this amendment, YA Global may convert such
additional amounts of the Debentures in accordance with their terms; provided,
however, that in no event shall such conversions result in the issuance of more
than 750,000 additional shares of Common Stock in the aggregate.
