(1)	Reflects all outstanding shares of Allos Therapeutics, Inc. ("Allos") not acquired in the tender offer described in the Tender Offer Statement on Schedule TO, as amended and supplemented, initially filed with the Securities and Exchange Commission on April 16, 2012 (the "Tender Offer") by Spectrum Pharmaceuticals, Inc. ("Spectrum") and Sapphire Acquisition Sub, Inc. ("Merger Sub"). On September 5, 2012, following completion of the Tender Offer, Allos merged with Merger Sub, with Allos surviving the merger as a wholly owned subsidiary of Spectrum pursuant to a "short-form merger" under Delaware law (the "Merger"). Outstanding shares of Allos not tendered in the Tender Offer are deemed acquired by Spectrum and Merger Sub upon consummation of the Merger.
(2)	Prior to the Merger, Spectrum held 1,000 shares of the common stock of Merger Sub, which represented all of the issued and outstanding capital stock of Merger Sub. At the effective time of the Merger, each share of Merger Sub was converted into a share of Allos stock. At the effective time of the Merger, all shares of Allos issued and outstanding immediately prior to the effective time were cancelled as a result of the Merger, in effect cancelling all shares of Allos held by Merger Sub.
