Bernstein Liebhard LLP is investigating whether the Board of Directors of RSC Holdings Inc. (“RSC” or the “Company”) (NYSE: RRR) breached its fiduciary duty to its shareholders in agreeing to sell RSC to United Rentals, Inc.

Under the terms of the agreement, each outstanding share of RSC common stock will be converted into the right to receive
$10.80 in cash and 0.2783 of a share of United Rentals common stock, subject to the terms and conditions of the merger
agreement. The investigation is focused on the potential unfairness of the price to RSC shareholders and the process by which the RSC Board of Directors considered and approved the transaction.

If you are interested in discussing your rights as a RSC shareholder and/or have information relating to the matter, please contact U. Seth Ottensoser at (877) 779-1414 or
