On June 28, 2008, a downward reset was triggered pursuant to the terms of the indenture resulting in an adjusted conversion rate of 39,024 shares of Common Stock for each $100,000 principal amount of the Notes. If, following the June 28, 2008 downward reset, CCIF Petrol Limited had converted its Notes in full (and no other holders of Notes had converted), CCIF Petrol Limited would have held 5.5% of the outstanding shares of Common Stock. On July 9, 2008, the Issuer’s shares of Common Stock underwent a 1 for 2 reverse split. On March 28, 2009, a downward reset was triggered pursuant to the terms of the indenture resulting in an adjusted conversion rate of 23,810 shares of Common Stock for each $100,000 principal amount of the Notes. Accordingly, as of the date hereof, the Notes held by CCIF Petrol Limited may be converted in 1,119,048 shares of Common Stock.

The percentages used in this Item 4 are calculated based upon 15,942,336 ordinary shares issued and outstanding as of December 31, 2008.
