With this proposal being the sole purpose of the adjourned Stockholders' Meeting scheduled for September, 4, 2009, there is no need to hold the meeting on September 4th. As previously announced, the 2009 Annual Meeting of Stockholders was held as scheduled on June 24, 2009 at which three of the four proposals passed. The Company left the polls open with regard to voting on proposal 3, an amendment of its Certificate of Incorporation to increase the number of authorized shares of Common Stock from 200,000,000 to 350,000,000, and adjourned the meeting solely with regard to this proposal. The Company did this due to the low vote turn out and the requirement that this proposal be approved by the holders of a majority of the outstanding shares. Less than the requisite number of shares for approval of the proposal were present at the original meeting. The Company believes that the low turnout of Stockholders as of the May 8, 2009 Record Date was due to the fact that more than 40% of its outstanding shares were held outside the United States with many of these shares are held at European banks that do not necessarily participate in the voting of proxies of American companies.
