those items which are hereby reported are amended. All other items remain
unchanged. All capitalized items shall have the meanings assigned to them in
the Schedule 13D, as amended to date, unless otherwise indicated herein.
ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION
Item 3 is hereby amended to delete the second sentence of the second
paragraph thereof. Item 3 is hereby further amended to delete the third
paragraph thereof in its entirety and to substitute in place thereof the
following:
Since the filing of Amendment No. 2 to Schedule 13D dated November 25,
1997, the Reporting Persons and the Issuer have entered into a Stock
Purchase Agreement dated January 29, 1999 (the "Stock Purchase
Agreement") and a Secured Promissory Note dated March 25, 1999 (the
"Note"). Pursuant to the Stock Purchase Agreement, (i) 61,350 shares of

price of approximately $6.52 pursuant to Tako's pre-existing right to
purchase its pro rata share of securities to be issued by the Issuer
(the "Pre-emptive Right") pursuant to Section 5.1 of that certain
Convertible Note, Option and Warrant Purchase Agreement dated as of June
17, 1997 (the "Original Purchase Agreement"); (ii) 107,333 shares of the
Issuer's Common Stock were issued to Tako pursuant to the anti-dilution
rights granted to Tako by Section 1.2 of the Original Purchase
Agreement; and (iii) non-redeemable Warrants to purchase 775,000 shares
of the Issuer's Common Stock were issued to Tako, 230,000 shares of
which are exercisable at $10.35 per share and 545,000 shares of which are
exercisable at $13.50 per share, in consideration for the cancellation of

issuance by the Issuer to Tako of the Note, non-redeemable Warrants to
purchase 500,000 shares of the Issuer's Common Stock were issued to
Tako which are exercisable at $11.00 per share.
Tako has the right to acquire an aggregate 1,775,000 shares of the
Issuer's Common Stock upon the exercise of its Warrants, of which
230,000 shares are exercisable at $10.35 per share, 1,045,000 shares are
exercisable at $13.50 per share and 500,000 shares are exercisable at

The second paragraph of Item 4 is hereby amended to add at the end:
The Issuer's outstanding Common Stock increased by 168,683
shares pursuant to the Stock Purchase Agreement and in the event of
the exercise of Warrant No. 4 would increase by an additional 500,000
shares.

the Option, and pursuant to the Stock Purchase Agreement. Upon exercise
of the Warrants, the Reporting Persons would have sole voting and

the following new paragraph:
Since the filing of Amendment No. 2 to Schedule 13D on November 25, 1997,
the Reporting Persons and the Issuer have entered into the Stock
Purchase Agreement and the Note. Pursuant to the Stock Purchase
Agreement, (i) 61,350 shares of the Issuer's Common Stock were issued
