("RAM") is a party to (i) a Voting Agreement dated as of July 22, 2007 by and among RAM, RAM Acquisition Corp., a wholly owned subsidiary of RAM ("Merger Sub"), each of the entities set forth on Schedule A thereto and, for limited purposes, United Rentals, Inc. (the "Company") (the "Voting Agreement") and (ii) a Warrant Holders Agreement dated as of July 22, 2007 by and among RAM, Merger Sub, certain holders of warrants for common stock of the Company that are parties thereto and, for limited purposes, the Company (the "Warrant Holders Agreement", and together with the Voting Agreement, the "Stockholders Agreements"). The Stockholders Agreements were entered into in connection with an Agreement and Plan of Merger dated as of July 22, 2007 by and among RAM, Merger Sub and the Company (the "Merger Agreement").
(2) Pursuant to the Stockholders Agreements, RAM has shared voting power and certain other rights with respect to 24,426,981 shares of common stock, par value $0.01 per share (the "Shares"), of the Company that are the subject of the Stockholders Agreements. As a result, RAM may be deemed to beneficially own such Shares. Neither the filing of this Form 3 nor any of its contents shall be deemed to constitute an admission by RAM or any other person that it is the beneficial owner of any of the securities referred to herein for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended, or for any other purpose, and such beneficial ownership is expressly disclaimed.
(3) Pursuant to the Voting Agreement, at the Effective Time (as defined in the Merger Agreement), the shares of Series C Preferred Stock of the Company and Series D Preferred Stock of the Company subject to the Voting Agreement shall automatically convert into the right to receive an amount in cash equal to the Series C Preferred Stock Merger Consideration and the Series D Preferred Stock Merger Consideration, as applicable (as defined in the Merger Agreement). Pursuant to the Warrant Holders Agreement, prior to the Effective Time, holders of warrants subject to the Warrant Holders Agreement shall exercise their warrants in accordance with the terms of the warrants. The Shares issuable upon the exercise of such warrants shall be entitled to receive Common Stock Merger Consideration (as defined in the Merger Agreement) in connection with the consummation of the merger of Merger Sub with and into the Company.
