The ratio of earnings to fixed charges is unaudited for all periods presented. For purpose of calculating this ratio, earnings consist of net income (loss) plus income taxes and fixed charges. Fixed charges consist of interest expense and the estimated portion of rental expense deemed a reasonable approximation of this interest factor. For the year ended June 30, 2007 on an actual and pro forma basis to give pro forma effect to the issuance of $15 million in principal amount of additional notes and the plan of reorganization as if they had been completed on July 1, 2006, we had a deficiency of earnings to fixed charges of approximately $96.7 million and $80.5 million, respectively. For the years ended June 30, 2006 and 2005 we had a deficiency of earnings to fixed charges of approximately $224.8 million and $12.1 million, respectively.
