The Warrants have an exercise price of $4.25 per share and are not exercisable until six months after the closing of the transaction. The transaction is expected to provide gross proceeds of approximately $13.3 million to Cytogen before deducting costs associated with the offering, and will be used primarily for general corporate purposes, including the selling, marketing and clinical development of Cytogen's products and product candidates. The parties expect to close the transaction as soon as possible. The placement agent in this transaction will receive compensation consisting of (i) a cash fee equal to 5% of the aggregate gross proceeds and (ii) warrants to purchase shares equal to 5% of the aggregate shares sold in the transaction (collectively with the warrants described above, the "Warrants").
