__________________________________________________
As originally provided in the Prospectus, the Company issued to
D. H. Blair Investment Banking Corp. ("Blair") a warrant dated January 1,
1995, ("Blair Warrant") to purchase up to 75,000 shares of Common Stock,
in connection with an extension of a promissory note. The Blair Warrant
was partially assigned to the following officers and directors of Blair
as follows: a warrant for the purchase of 28,000 shares of Common Stock
was assigned to J. Morton Davis; a warrant for the purchase of 28,000
shares of Common Stock was assigned to Esther Stahler; a warrant for the
purchase of 7,000 shares of Common Stock was assigned to Ruki Renov; and,
a warrant for the purchase of 5,000 shares of Common Stock was assigned
to Martin Bell. Blair was left with a warrant ("Blair Remainder
Warrant") for the purchase of 7,000 shares of Common Stock. The shares
of Common Stock are described under "Summary of Securities Being Offered"
in the Prospectus, are referred to in other portions of the Prospectus
and are covered by the Prospectus. Pursuant to anti-dilution adjustments
provided for in such warrant, the exercise price of the Blair Warrant was
reduced in 1996 from $2.375 per share of Common Stock to $1.9360 per
share of Common Stock and such exercise price was subject to further
reduction as a result of transactions occurring after the 1996
adjustment. On January 6, 2000, Davis, Renov and Bell assigned all of
their portions of the Blair Warrant back to Blair and Stahler assigned a
portion of the Blair Warrant back to Blair allowing the purchase of
20,000 shares of Common Stock. Also on January 6, 2000, the Blair
Warrant was amended to (i) reduce the exercise price thereof from $1.9360
per share of Common Stock to $1.00 per share of Common Stock and (ii)
extend the expiration date of the warrant from December 31, 1999 to
January 14, 2000. Such warrant was not otherwise amended.
As originally provided in the Prospectus, the Company issued to JW
Genesis Financial Corp. ("Genesis") (f/k/a JW Charles Financial Services,
Inc.) a warrant dated June 9, 1997 ("Genesis Warrant"), to purchase up to
100,000 shares of Common Stock, in connection with the RBB Series 4
Private Placement. On January 6, 2000, Genesis assigned a portion of the
Genesis Warrant ("Mannion Warrant") allowing the purchase of 50,000
shares of Common Stock to Paul T. Mannion ("Mannion") and the Mannion
Warrant was amended to provide that the exercise price thereof was
reduced from $1.50 per share of Common Stock to $1.00 per share of Common
Stock if exercised prior to February 10, 2000. Such warrant was not
otherwise amended.
Effective February 9, 2000, Genesis assigned the 1996 Genesis
Warrant in its entirety to Mannion. The shares of Common Stock issuable
upon exercise of the 1996 Genesis Warrant are covered by the 1996
Registration Statement.
In conjunction with the above, the table below supplements and
amends, in part, the Selling Security Holders table set forth at page 50
of the Prospectus by (i) adding Paul T. Mannion as a Selling Shareholder,

Warrant, (iii) adjusting the offering information applicable to Davis,
Stahler, Revov and Bell to account for their assignments of portions of
the Blair Warrant, (iv) adjusting the offering information applicable to
