$30,000,000 principal amount of 7.95% Convertible Senior Notes due 2015

     This Prospectus Supplement No. 1 supplements the prospectus dated July 20, 2010 (the “Prospectus”), which forms a part of our Registration Statement on Form S-3 (Registration Statement No. 333-167802). This prospectus supplement is being filed to update and amend certain of the information included in the Prospectus under the section “Selling Securityholders”.

     The Prospectus and this prospectus supplement relate to the disposition of up to $30,000,000 principal amount of our 7.95% Convertible Senior Notes due 2015 (the “Notes”), and up to 13,367,490 shares of our common stock, par value $0.01 per share (the “Common Stock”) issuable upon conversion of the Notes, that may be sold by the selling securityholders identified in the Prospectus. We have registered the offer and sale of the Notes and such shares of common stock to satisfy registration rights we have granted. We will not receive any of the proceeds from the sale of the Notes or shares of common stock by the selling securityholders.

     Our common stock is listed on the New York Stock Exchange under the symbol “GBE.” On November 15, 2010, the last reported sales price for our common stock was $1.09.

     This prospectus supplement should be read in conjunction with the Prospectus, which is to be delivered with this prospectus supplement. This prospectus supplement updates, amends and supplements the information included or incorporated by reference in the Prospectus. If there is any inconsistency between the information in the Prospectus and this prospectus supplement, you should rely on the information in this prospectus supplement.

     Investing in the Notes or the Common Stock involves a high degree of risk. You should review carefully the risks and uncertainties described under the heading “Risk Factors” beginning on page 7 of the Prospectus, and under similar headings in any amendments or supplements to the Prospectus.

     Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if the Prospectus or this prospectus supplement is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus supplement is November 15, 2010.

SELLING SECURITYHOLDERS

          We are registering the Notes and shares of Common Stock issuable upon conversion of the Notes in order to permit the selling securityholders to offer the Notes and shares for resale from time to time. Except for the ownership of the Notes, and with respect to certain selling securityholders, the ownership of shares of our Common Stock and 12% Preferred Stock, the selling securityholders have not had any material relationship with us within the past three years.

          The table below lists the selling securityholders and other information regarding the beneficial ownership of the Notes and the shares of Common Stock by each of the selling securityholders, based upon information we have received from or on behalf of the selling securityholders through the date hereof. The second column lists the principal amount of the Notes beneficially owned by each selling securityholder as of November 15, 2010. The third column lists the number of shares of Common Stock beneficially owned by each selling securityholder, based on its ownership of the Notes, as of November 15, 2010, assuming conversion of all of the Notes held by the selling securityholders on that date, without regard to any limitations on conversions or exercise.

          The fourth column lists the principal amount of the Notes being offered under this prospectus by each selling securityholder. The fifth column lists the shares of Common Stock being offered under this prospectus by each selling securityholder.

          Because the conversion price of the Notes may be adjusted, we may issue a number of shares of Common Stock that may be more or less than the number of shares being offered under this prospectus. The sixth and seventh columns assume the sale of all of the shares offered by the selling securityholders under this prospectus.
