                              PLAN OF DISTRIBUTION

       In October and December, 2000, we received a total of $12,500,000 from
the Investors in return for promissory notes in the aggregate principal amount
of $12,500,000. The notes bore interest at the rate of 6% per annum. Each
Investor had an equal interest in the notes and the transaction.

       We agreed to pay the notes by issuing shares of common stock to the
Investors and to use the proceeds to pay the notes. Through December 2000 we
sold $4,200,000 of our common stock to the Investors to date in seven weekly
settlements, delivering an aggregate of 1,671,094 shares of our common stock.
The price for these sales was 92% of the daily volume weighted average trading
price of our common stock for each week during the sales period.

       From January 2, 2001, through April 3, 2001, we completed payment of the
notes by selling $8,300,000 of our common stock to the Investors in thirteen
weekly settlements, delivering an aggregate of 4,077,802 shares. The price for
these sales was 91% of the daily volume weighted average trading price of our
common stock for each of the sixty-four trading days comprising the period of
the sales. We paid the interest on the notes with cash.

       We also sold $2,500,000 of our common stock to the Investors on February
22, 2001, delivering an aggregate of 1,146,788 share at a negotiated price of
$2.18 per share. In addition on April 3, 2001, we sold $930,000 of common stock
to Strong River Investments, Inc., at a negotiated price of $1.55 per share,
delivering 600,000 shares. These sales were in lieu of certain options to
purchase shares in favor of the Investors.

       We sold the shares of common stock described in this Prospectus
Supplement directly to the Investors in a privately-negotiated transaction in
which no party is acting as an underwriter. We have agreed to pay Intellect
Capital Ltd. a placement fee equal to 7% of the equity raised from these
transactions. Terren S. Peizer, one of our directors, is an affiliate of

                                 USE OF PROCEEDS

       The aggregate net proceeds from the sale of all of the shares of common
stock to the Investors were approximately $14,810,000. We have used the net
