Prospectus Summary
The following summary is qualified in its entirety by the more detailed information and the Consolidated Financial Statements and notes thereto appearing elsewhere in this Prospectus. Except as otherwise noted herein, information in this Prospectus (i) assumes no exercise of the U.S. Underwriters' over-allotment option, (ii) includes the April 1997 Series C Preferred Stock financing as though it had occurred as of March 31, 1997 and (iii) assumes the conversion of all outstanding shares of Preferred Stock of the Company into shares of Common Stock of the Company, which will occur upon the closing of this offering. The number of shares of Common Stock shown as outstanding throughout the Prospectus assumes no adjustment to the number of shares of Series A Common Stock issuable upon conversion of the Series C Preferred Stock since any such assumption would be arbitrary prior to the determination of an estimated price range or initial public offering price per share.
