13D Group
On November 13, 2007, a group of stockholders of the Company, consisting of Mark A. Emalfarb, The Pinnacle Fund, L.P., Barry M. Kitt, The Francisco Trust U/A/D February 28, 1996, Tom Juda, Nancy Juda, J. Steven Emerson and David M. Knott (collectively, the "13D Group") filed a statement on Schedule 13D with the SEC reporting that they beneficially owned an aggregate of 16,392,159 shares, or 52.4%, of the Company's issued and outstanding common stock as of October 31, 2007 and had agreed to act as a group for the purpose of voting all shares of the Company's common stock owned or controlled by them pursuant to a voting agreement (the "Voting Agreement") entered into as of October 31, 2007. For additional information regarding the 13D Group, the Voting Agreement and other related information, see the Schedule 13D filed by the 13D Group with the SEC on November 13, 2007 and the Schedule 13D/A filed by the 13D Group with the SEC on April 15, 2008. These documents can be accessed on the SEC's Internet website at http://www.sec.gov.

On or about April 25, 2008, the Company received a notice from The Mark A. Emalfarb Trust U/A/D October 1, 1987 (the "Emalfarb Trust"), one of the parties to the Voting Agreement, of its intention to appear in person or by proxy at the annual meeting to nominate Mark A. Emalfarb, Seth J. Herbst and Robert D. Burke for election as the Class III and Class I directors. In addition, in its notice, the Emalfarb Trust informed the Company that Mark A. Emalfarb had obtained irrevocable proxies from the parties to the Voting Agreement (and/or certain persons or entities affiliated with them) authorizing Mr. Emalfarb to vote approximately 50.1% of the Company's issued and outstanding common stock, including at the annual meeting.

The Company has not independently verified, and takes no responsibility for, the accuracy or completeness of any information contained in the 13D Group's Schedule 13D filings, as amended, the notice from the Emalfarb Trust or any information otherwise provided by the Emalfarb Trust, any member of the 13D Group or any of their respective affiliates.

Deregistration and Suspension of Duty to File Reports As previously disclosed in a Current Report on Form 8-K filed by the Company with the SEC on March 4, 2008, pursuant to the filing of Form 25 (File No. 001-32513) by the American Stock Exchange with the SEC on January 30, 2008, the Company's common stock was automatically withdrawn from registration under Section 12(b) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), effective April 29, 2008.

Pursuant to Section 15(d) of the Exchange Act, the Company's duty to file reports (including Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K) with the SEC was automatically suspended for the fiscal year ending December 31, 2008 (the "2008 Fiscal Year") because the Company had fewer than 300 holders of record of its common stock at the beginning of the 2008 Fiscal Year.

Consequently, among other things, the Company is no longer required to file reports with the SEC for at least the remainder of the 2008 Fiscal Year and until such time (if ever) that the Company has 300 or more holders of record of its common stock at the beginning of any fiscal year in the future; and the Company is no longer subject to the proxy rules under Section 14 of the Exchange Act.

Notwithstanding the foregoing, the Company currently intends to continue, when and if it deems appropriate -- through the filing of Form 8-Ks and/or the issuance of press releases -- to inform its stockholders of the occurrence of events that the Company deems to be important to its stockholders.

On May 13, 2008, the Company filed with the SEC a Current Report on Form 8-K, which includes a copy of this press release and a copy of the notice of its annual meeting of stockholders as exhibits.
