(1) As of the date hereof, Millenco LLC, a Delaware limited liability company ("Millenco") (formerly known as Millenco, L.P.) was the beneficial owner of 1,772,125 warrants ("Warrants") to purchase shares of the Issuer's common stock, par value $0.0001 per share ("Common Stock"). Each Warrant, which became exercisable upon the Issuer's completion of its acquisition of InfuSystem, Inc. on October 26, 2007, entitles the holder to purchase one share of the Issuer's Common Stock at a price of $5.00 per share. The Warrants will expire on April 11, 2011, or earlier upon redemption.
(2) Millennium Management LLC, a Delaware limited liability company ("Millennium Management"), is the manager of Millenco, and consequently may be deemed to have shared voting control and investment discretion over securities owned by Millenco. Israel A. Englander ("Mr. Englander") is the managing member of Millennium Management. As a result, Mr. Englander may be deemed to have shared voting control and investment discretion over securities deemed to be beneficially owned by Millennium Management. The foregoing should not be construed in and of itself as an admission by Millennium Management or Mr. Englander as to beneficial ownership of the shares owned by Millenco.
