Fourth Supplement to Prospectus dated December 30, 1994
___________________________________________
As originally provided in the Prospectus, the Company issued
to D. H. Blair Investment Banking Corporation ("Blair") a warrant
dated February 10, 1992, ("Blair Warrant Two") to purchase up to
206,701 shares of Common Stock, in connection with a loan made to
the Company, which 206,701 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 Two was
reduced from $3.02 per share of Common Stock to $2.1475 per share
of Common Stock. As described in the Third Supplement to the
Prospectus dated December 30, 1994, dated February 17, 1997 ("Third
Supplement"), the Blair Warrant Two was amended on February 7, 1997,
to (i) reduce the exercise price thereof from $2.1475 per share of
Common Stock to $1.00 per share of Common Stock and (ii) extend the
expiration date of the warrant from February 10, 1997, to March 3,
1997. Such warrant was not otherwise amended.
Effective February 25, 1997, Blair assigned the Blair Warrant
Two to certain partners, officers and brokers of Blair (the "Blair
Warrant Two Assignees"). Accordingly, each Blair Warrant Two
Assignee not previously listed as a Selling Shareholder is added as
an additional Selling Shareholder in the Prospectus. The table
below supplements and amends the Selling Security Holders table set
forth at pages 29 through 36 of the Prospectus by (i) adding as a
Selling Stockholder each Blair Warrant Two Assignee who was not
previously listed as a Selling Stockholder, and (ii) adjusting the
offering information applicable to Blair, Richard Molinsky, Victor
Molinsky, Leonard Solomon, and Murray Zung to account for the
assignment by Blair of the Blair Warrant Two. The number of shares
of Common Stock and the number of Class B Warrants covered by the
Prospectus remains unchanged. Except with respect to each Selling
Stockholder listed below, and except as supplemented and amended by
the First Supplement to the Prospectus dated December 30, 1994,
dated January 11, 1995, the Second Supplement to the Prospectus
dated December 30, 1994, dated March 24, 1995, and the Third
Supplement, the Selling Security Holders table set forth at pages
29 through 36 of the Prospectus remains unchanged.
