The information contained in Item 3.03 "Material Modification to Rights of Security Holders" is incorporated herein by reference. In addition to the "Preference in Liquidation" described above, the significant rights and preferences attaching to the Series B Preferred Stock are as follows.

Dividends

The holders of Series B Preferred Stock are entitled to receive cumulative dividends at the rate of $0.06 per share (as adjusted for any stock dividends, combinations or splits with respect to such shares) per annum, payable out of funds legally available therefor. Dividends shall be payable on a calendar quarter basis. Any quarterly dividends not paid when due shall be accrued and shall accumulate until paid.

Voting Rights

The holders of the Company's Series B Preferred Stock are entitled to such number of votes per share as equals the number of common shares into which each share of Series B Preferred Stock is convertible on the record date for determination of the shareholders entitled to vote.

Conversion

Each share of Series B Preferred Stock is convertible, at the option of the holder, into fully paid and non-assessable common shares on a one-for-one basis, subject to certain adjustments. The Series B Preferred Stock will automatically convert into common shares on a one-for-one share basis effective the first trading day after the reported high selling price for the Company's common shares on any international, national or regional securities exchange or inter-dealer quotation system including but not limited to, NASDAQ, the Pink Sheets or the Over-the-Counter Bulletin Board, is at least $1.50 per share for any consecutive ten consecutive trading days. If an automatic conversion occurs within one year after the Series B Preferred Stock was purchased from the Company, a holder will receive, on the one-year anniversary date of his, her or its purchase, a cash dividend equivalent to a full year of dividends less any dividends paid before such conversion.

Redemption

Commencing two years after the issuance of shares of Series B Preferred Stock, the Company may redeem in cash, from any funds legally available therefor, any or all outstanding Series B Preferred Stock by paying an amount equal to $0.75 per share (as adjusted for any stock dividends, combinations or splits with respect to such shares), plus all accrued or declared but unpaid dividends on such shares.
