Item 4.
Purpose of Transaction.
 
The Reporting Persons purchased the Shares and Notes based on the Reporting Persons’ belief that the Shares and Notes, when purchased, were undervalued and represented an attractive investment opportunity.  The Reporting Persons currently intend to engage in discussions with management and the Board of the Issuer concerning actions within their control that in the Reporting Persons’ view can dramatically increase profitability and unlock value for shareholders.  The Reporting Persons also intend to engage in discussions with management and the Board of the Issuer regarding seeking Board representation. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of Shares or Notes at prices that would make the purchase or sale of Shares or Notes desirable, the Reporting Persons may endeavor to increase or decrease their position in the Issuer through, among other things, the purchase or sale of Shares or Notes on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.
 
No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein.  The Reporting Persons intend to review their investment in the Issuer on a continuing basis.  Depending on various factors including, without limitation, the Issuer’s financial position and investment strategy, the price levels of the Shares and the Notes, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, engaging in communications with management and the Board of the Issuer, engaging in discussions with stockholders of the Issuer and others about the Issuer and the Reporting Persons’ investment, making proposals to the Issuer concerning changes to the capitalization, ownership structure, board structure, including seeking board representation, or operations of the Issuer, purchasing additional Shares or Notes, selling some or all of their Shares or Notes, engaging in short selling of or any hedging or similar transaction with respect to the Shares or the Notes, or changing their intention with respect to any and all matters referred to in Item 4.
 
Item 5.
Interest in Securities of the Issuer.
 
The aggregate percentage of Shares reported owned by each person named herein is calculated using as the numerator the respective Shares held by each Reporting Person, including Shares issuable upon conversion of the Notes, and as the denominator 240,500,000 Shares outstanding, as of August 3, 2012, which is the total number of Shares outstanding as reported in the Issuer’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on August 9, 2012, plus the number of Shares issuable upon conversion of the Notes held by such Reporting Person.
