This Amendment No. 1 amends the Schedule 13D filed on December 21, 2011 (the “Schedule 13D”), by United Rentals, Inc. (the “Reporting Person”). Capitalized terms used herein not otherwise defined shall have the meaning ascribed to them in the Schedule 13D. The Voting Agreement entered into by the Reporting Person and the Oak Hill Stockholders has been terminated in accordance with its terms. Consequently, the Reporting Person can no longer be deemed the beneficial owner of any shares of RSC Common Stock. Accordingly, this Amendment No. 1 is the Reporting Person’s final amendment to the Schedule 13D and is an exit filing.

Item 4.

Purpose of Transaction

Item 4 of the Schedule 13D is hereby supplemented by adding the following two paragraphs:

On April 30, 2012, the parties to the Merger Agreement consummated the Merger. Pursuant to the terms of the Merger Agreement, each share of RSC Common Stock issued and outstanding immediately prior to the effective time (other than shares owned by (i) RSC, United Rentals or any direct or indirect wholly owned subsidiary of RSC or United Rentals and (ii) stockholders who have perfected and not withdrawn a demand for appraisal rights under Delaware law) was automatically converted into the right to receive $10.80 in cash and 0.2783 of a share of common stock of United Rentals, without interest. Also pursuant to the terms of the Merger Agreement, on April 30, 3012, the size of United Rentals’ board of directors was increased to 14 directors and three of RSC’s independent directors, Pierre E. Leroy, James H. Ozanne, and Donald C. Roof, were elected to United Rentals’ board of directors.

The Voting Agreement terminated, in accordance with its terms, upon the effective time of the Merger, which was April 30, 2012.

Item 5.

Interest in Securities of the Issuer

Item 5 of the Schedule 13D is hereby amended, restated and replaced in its entirety by the following:

(a) and (b) The responses of the Reporting Person to Rows (7) through (13) of the cover page of this Amendment No. 1 are incorporated herein by reference As of April 30, 2012, following the consummation of the Merger, the Reporting Person owns no shares of RSC Common Stock. To the knowledge of the Reporting Person, no person named in Schedule A beneficially owns shares of RSC Common Stock.

Except as set forth above, neither United Rentals, nor to the best of United Rentals’ knowledge, any of the individuals named in Schedule A hereto, beneficially owned, or had the sole power to vote or to direct the vote, shared power to vote or to direct the vote, sole power to dispose or direct the disposition of, or shared power to dispose or direct the disposition of, any shares of RSC Common Stock.

Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that United Rentals was the beneficial owner of the RSC Common Stock referred to herein for purposes of Section 13(d) of the Exchange Act or for any other purpose, and such beneficial ownership is expressly disclaimed.
