1.       For each selling stockholder, this number represents the number of
         shares of common stock that would be beneficially owned by such
         selling stockholder after the conversion of the Notes beneficially
         owned by such selling stockholder as of June 11, 2004, assumes that
         the selling stockholders will sell all shares of common stock offered
         by them under this prospectus, and further assumes that all of the
         Notes have been converted.

2.       For each selling stockholder, this number represents the percentage
         of common stock that would be owned by such selling stockholder after
         completion of the offering, based on the number of shares of common
         stock outstanding as of June 11, 2004 and assuming all the Notes
         beneficially owned by such selling stockholder as of June 11, 2004,
         have been converted.

3.       We have been advised that Mr. Lawrence Keele may be deemed the
         beneficial owner of these shares by virtue of his voting control and
         investment discretion.

4.       Assumes conversion of 100% of the outstanding Notes (without giving
         effect to any capital adjustments). We note that the aggregate number
         of shares of common stock requested to be registered by the selling
         stockholders is greater than the total number of shares initially
         issuable upon conversion of 100% of the outstanding Notes. This may
         be due in part to sales or other transfers of Notes among the selling
         stockholders in which the person acquiring the Notes submits a
         request to register shares of common stock which were previously
         registered by the person who sold the Notes.
