$1,200,000 principal amount of its 10% Six Month Notes (the "Old Notes") issued

accompanying Warrants to purchase shares of the Common Stock, $.001 par value
per share (the "Common Stock"), of the Company at an exercise price of $2.375
per share. Pursuant to this offer of exchange, the Company is offering to
exchange, effective as of the maturity of the Old Notes, the Old Notes for
promissory notes (the "New Notes") in like principal amount, bearing the same
interest and providing for one year of quarterly payments of interest only,
followed by a second year with quarterly payments equal to 25% of the original
principal amount plus accrued interest on the unpaid principal, which New Notes
will be convertible into shares of the Company's Common Stock at the rate of
$1.10 of principal for each share of Common Stock (the "Conversion Price"). In
addition, pursuant to this offer of exchange, the outstanding warrants (the "Old
Warrants") will be exchanged for warrants (the "New Warrants") providing for the
purchase of three times the number of shares of Common Stock covered by Old
Warrants at a price per share of $1.10 (the "New Exercise Price"). The New Notes
and New Warrants will be dated the Maturity Date of the Old Notes.

            Both the Conversion Price and the New Exercise Price are set at the
average closing price of the Common Stock for the month of March, 1999, the
month of the original maturity of the Old Note. The form of New Notes and New
Warrants are attached hereto as Exhibit A and B, respectively. Upon surrender of
your Old Notes and Old Warrants, the New Notes and New Warrants will be issued
and promptly delivered to you.

            This offer of exchange will remain open until the close of business
on May 21, 1999 and may be accepted by any Holder by executing and faxing to the
Company a copy of this offer in the space provided below. Upon receipt of
acceptance by a Holder, the Old Notes and Old Warrants held by such Holder shall
be deemed amended to reflect the terms of the New Notes
