In accordance with the terms of the Definitive Agreement, which was negotiated in an arm’s length transaction, OrthoLogic paid Chrysalis $2.5 million in cash and issued 3,462,124 shares of OrthoLogic common stock, valued at $25.0 million, for substantially all of Chrysalis’ assets, including its key intellectual property asset, an exclusive worldwide license to develop, manufacture and market Chrysalin-based products for all indications. Prior to the transaction, OrthoLogic held an exclusive sublicense from Chrysalis for all orthopedic indications. In addition to the consideration paid at closing, OrthoLogic will issue the number of shares equal to an additional $7.0 million in OrthoLogic common stock to Chrysalis upon the occurrence within five years from the August 5, 2004 closing date of certain future trigger events, including the acceptance for filing by the U.S. Food and Drug Administration (FDA) of a New Drug Application (NDA) for a Chrysalin-based product or the sale of OrthoLogic or a similar corporate transaction resulting in a change of control.
