The 1,500,000 warrants include the following: o 600,000 Series 2001C warrants entitling the holder to purchase one common share at an exercise price of $1.50 per share at any time prior to the earlier of (i) December 14, 2006, and (ii) the 180th day following the date on which the closing price of the common shares on the Nasdaq National Market has equaled or exceeded U.S. $2.50 for 10 days, whether or not consecutive. o 600,000 Series 2001D warrants entitling the holder to purchase one common share at an exercise price of $2.00 per share at any time prior to the earlier of (i) December 14, 2006, and (ii) the 180th day following the date on which the closing price of the common shares on the Nasdaq National Market has equaled or exceeded U.S. $3.00 for 10 days, whether or not consecutive; and o 300,000 Series 2001E warrants entitling the holder to purchase one common share at an exercise price of $2.50 per share at any time prior to the earlier of (i) December 14, 2006, and (ii) the 180th day following the date on which the closing price of the common shares on the Nasdaq National Market has equaled or exceeded U.S. $3.50 for 10 days, whether or not consecutive. Mr. Schnur acquired 200,000 common shares and 200,000 warrants in a private placement pursuant to the terms of a stock purchase agreement dated as of July 23, 2001. The 200,000 warrants include 100,000 Series 2001A warrants entitling the holder to purchase one common share at an exercise price of $2.50 per share at any time prior to the earlier of (i) July 23, 2006, and (ii) the date sixty days following the fifth day (whether or not consecutive) the closing price of the common shares equals or exceeds $3.50 and 100,000 Series 2001B warrants entitling the holder to purchase one common share at the exercise price specified below at any time prior to the earlier of (i) July 23, 2006, and (ii) the date sixty days following the fifth day (whether or not consecutive) the closing price of the common shares equals or exceeds $4.50. The exercise price for the Series 2001B warrants was $3.50 per share when the warrants were issued but was reduced to $1.05 per share pursuant to a warrant repricing agreement we entered into with Mr. Schnur on April 16, 2002. S-2 Mr. Schnur acquired 800,000 common shares and 800,000 warrants in a private placement pursuant to the terms of a stock purchase agreement dated as of June 19, 2001.

The exercise price for the Series 2001B warrants was $3.50 per share when the warrants were issued but was reduced to $1.05 per share pursuant to a warrant repricing agreement we entered into with Mr. Schnur on April 16, 2002. Mr. Schnur acquired 82,500 Series 2000A warrants in a private placement pursuant to the terms of a stock purchase agreement dated as of March 26, 2001. The 82,500 Series 2000A warrants permit the holder to purchase up to 82,500 common shares at the exercise price specified below at any time prior to the earlier of (i) March 26, 2006, and (ii) the date thirty days following the fifth day (whether or not consecutive) the closing price of the common shares equals or exceeds $8.00.

All of the warrants held by Mr. Schnur include standard anti-dilution provisions pursuant to which the exercise price and number of shares issuable thereunder is adjusted proportionately in the event of a stock split, stock dividend, recapitalization or similar transaction. In addition, all of the warrants held by Mr. Schnur contain a provision which provides that the holder may not exercise the warrant if such exercise would result in the holder, together with any affiliate thereof, beneficially owning in excess of 9.999% of our then issued and outstanding common shares. The shares that may be offered pursuant to this prospectus include the common shares issued to Mr. Schnur and issuable upon the exercise of the warrants held by Mr. Schnur. Doral 18, LLC ------------- On December 28, 2001, pursuant to a note termination and issued agreement, we issued Doral 18, LLC a warrant to purchase 200,000 common shares, a contingent warrant to purchase up to 500,000 common shares and a $2,000,000 Secured Term Note in connection with the termination of our $7,000,000 10% Asset-Backed Exchangeable Term Note. The Secured Term Note is in the principal amount of $2,000,000 and bears interest at a rate of 11% per annum. Under the Secured Term Note, we are required to make monthly interest payments on or before the 28th day of each calendar month. If we do not make interest payments in cash on or before the due date, the holder will receive the right to exchange the amount of the monthly interest payment into common shares at a price equal to 75% of the average closing price of the common shares as reported by Bloomberg for the five preceding trading days. Under certain circumstances specified in the Secured Term Note, we are required to make interest payments in cash. The principal amount of the Note is not subject to exchange for common shares. The entire principal balance is due in full on March 31, 2003. We may prepay the Secured Term Note subject to a prepayment penalty equal to 5% of the principal amount being prepaid. Pursuant to a Registration Rights Agreement we have registered, and Doral is permitted to offer and sell pursuant to this prospectus, 550,000 common shares issuable upon the exercise of exchange rights that may accrue under the Secured Term Note. Because we are required to redeem all interest payments under the Secured Term Note in cash if the market price of our common shares is below $1.00 per share, we believe that the maximum number of common shares that may be issued in connection with the Secured Term Note is 367,269 shares. S-3 The 200,000 warrants issued to Doral in connection with the Secured Term Note have an exercise price of $1.50 per share and are exercisable at any time on or before December 15, 2006. Of the 500,000 contingent warrants issued to Doral in connection with the Secured Term Note, 25,000 vest on the day following the first time after December 31, 2001 that the closing price of our common shares exceeds $2.00 for ten consecutive trading days. Thereafter, 25,000 additional warrants vest, up to a maximum of 500,000 warrants, on the day following the first time the closing price of the common shares exceeds a number greater than $2.00 that is evenly divisible by .5 (e.g. $2.50, $3.00, $3.50) for ten consecutive trading days. By way of illustration, if the closing price is $4.01 for ten consecutive trading days, the total number of warrants that shall have vested is 125,000 shares. Each vested contingent warrant permits the holder to purchase one common share at an exercise price of $.01 per share. The contingent warrants expire on the later of (i) March 31, 2003, or (ii) the date we pay the Secured Term Note in full. On June 7, 2001, Doral acquired warrants to purchase 300,000 common shares in a private placement in connection with an amendment to the now-terminated 10% Asset Backed Exchangeable Term Note. The warrants permit the holder to purchase up to 300,000 common shares at an exercise price of $1.50 at any time prior to the earlier of (i) December 15, 2005, and (ii) the date sixty days following the fifth day (whether or not consecutive) the closing price of the common shares equals or exceeds $12.00. On December 15, 2001, Doral acquired warrants to purchase 350,000 common shares in a private placement in connection with the original issuance of the now-terminated 10% Asset Backed Exchangeable Term Note. The warrants permit the holder to purchase up to 350,000 common shares at an exercise price of $1.50 at any time prior to the earlier of (i) December 15, 2005, and (ii) the date sixty days following the fifth day (whether or not consecutive) the closing price of the common shares equals or exceeds $12.00. All of the warrants held by Doral include standard anti-dilution provisions pursuant to which the exercise price and number of common shares issuable thereunder are adjusted proportionately in the event of a stock split, stock dividend, recapitalization or similar transaction. The shares that may be offered pursuant to this prospectus include the common shares issuable upon the exercise of the warrants held by Doral and upon exercise of any exchange rights that may accrue under the Secured Term Note. Pursuant to a registration rights agreement dated as of December 28, 2001 and entered into in conjunction with the note termination and issuance agreement, we are obligated to file a registration statement registering the common shares issuable upon the exercise of Secured Term Note and warrants held by Doral. The common shares issuable upon exercise of the 350,000 warrants issued to Doral on December 15, 2001 were previously registered on registration statement no. 333-54092.
