Item 4.

Ownership.

Provide the following information regarding the aggregate number and percentage of the class of securities of the issuer identified in Item 1.

(a)

Amount beneficially owned:

 

Each of PRB Investors, L.P., PRB Advisors, L.L.C., Stephen J. Paluszek and Andrew P. Bergman (collectively, the "Reporting Persons") may be deemed to beneficially own 944,085 shares of Common Stock.  This amount consists of 926,200 shares of Common Stock issuable upon the conversion of Series C Preferred Stock and 17,885 shares of Common Stock issuable upon the conversion of Series E Preferred Stock.  The 944,085 reported shares of Common Stock excludes 255,915 shares of Common Stock issuable upon the conversion of Series E Preferred Stock because the Series E Preferred Stock provides that a holder thereof does not have the right to convert the Series E Preferred Stock into Series C Preferred Stock to the extent that such conversion would result in the holder, together with its affiliates, owning or controlling in the aggregate more than a 4.99% voting ownership interest in the Issuer, excluding for the purpose of this calculation any reduction in ownership resulting from transfers by such holder and its affiliates of voting securities of the Issuer (the "Ownership Limitation").  Without the Ownership Limitation, the Reporting Persons would be deemed to beneficially own 1,200,000 shares of Common Stock.
