       In connection with completion of the audit of the Company's financial
       statements for the year ended December 31, 2003, it was noted that the
       Company had made an error in the application of Emerging Issues Task
       Force Consensus 00-27, "Application of Issue No. 98-5 to certain
       Convertible Instruments" ("EITF 00-27") in the determination of the value
       of the beneficial conversion features connected with the issuance of
       convertible securities with detachable warrants, which resulted in an
       audit adjustment increasing interest expense and common stock by
       $286,498. This is a complex area of accounting involving the computation
       of intrinsic values inherent in relative values of the instruments. It
       was determined that of the total non-cash interest expense adjustment,
       $147,620 applied to the second quarter and $138,878 applied to the third
       quarter. Results of the second and third quarters, as shown above, have
       been restated for the effects of the correction of this error.
