Supplementary Data (Unaudited)

        The following table presents our unaudited consolidated statements of operations data for each of the eight quarters in the period ended January 31, 2005. In our opinion, this information has been presented on the same basis as the audited consolidated financial statements included in a separate section of this report, and all necessary adjustments, consisting only of normal recurring adjustments, have been included in the amounts below to present fairly the unaudited quarterly results when read in conjunction with the audited consolidated financial statements and related notes. The operating results for any quarter should not be relied upon as necessarily indicative of results for any future period. We expect our quarterly operating results to fluctuate in future periods due to a variety of reasons, including those discussed in "Additional Factors That May Affect Future Results."
