(2,868,855) (9,598,860) (18,578,688) ============ ============ ============== Ratio of earnings to fixed charges ........................... * * * ============ ============ ============== * - The ratio of earnings to fixed charges is computed by dividing fixed charges into income before income taxes plus fixed charges. Fixed charges include interest expense and that portion of rental expense (one-third) deemed representative of the interest factor. The ratio of earnings to fixed charges is computed using pre-tax income. On this basis, earnings before fixed charges for the period August 25, 1995 (date of inception) to December 31, 1995, the years ended December 31, 1996, 1997 and 1998, the nine months ended September 30, 1998 and 1999 and the period from August 25, 1995 (date of inception) to December 31, 1999 were not adequate to cover fixed charges by $426,826, $1,743,635, $3,977,400, $36,658,917, $25,377,065, $42,237,083 and $85,043,861, respectively.
