        placement of 5,814,600 shares of its common stock at a price of $1.737 per

  Entry

                    of Equity
                    Securities.
  On
        July 6, 2007, Cytogen Corporation, a
        Delaware corporation (the "Company"), closed its previously announced private
        placement of 5,814,600 shares of its common stock at a price of $1.737 per
        share.  The purchasers also received warrants to purchase 2,907,301
        shares of common stock at an exercise price of $2.231 per share. The warrants
        have a term of five years. The gross proceeds from the private placement are
        approximately $10.1 million, before deducting costs associated with the
        offering. Rodman & Renshaw, LLC and Roth Capital Partners LLC acted as
        placement agents in this transaction.
  The
        placement agents in the transaction received aggregate compensation
        consisting of (i) cash fees equal to 6% of the gross proceeds and (ii) warrants
        to purchase 348,876 shares of common stock on the same terms as the
        investors.
  The
        securities sold in this
        private placement have not been registered under the Securities Act of
        1933, as amended (the "Act") and may not be offered or sold in
        the United States in the absence of an effective registration
        statement or exemption from the registration requirements under the Act. In
        accordance with the terms of the registration rights agreement to be entered
        into by the Company and the purchasers in connection with the closing of the
        financing, the Company has agreed to file a resale registration statement on
        Form S-3 within 30 days after the closing of the transaction for purposes of
        registering, pursuant to the Act, the shares of common stock and shares of
        common stock underlying the warrants acquired by the investors. The Company
        believes that the issuance of the securities in this transactions were exempt
        from registration under Section 4(2) of the Securities Act of 1933.
  A
        complete copy of each of the
        Securities Purchase Agreement, the form of Warrant, the Registration Rights
        Agreement, and the related press release of the Company, dated June 29, 2007,
