UNITED RENTALS REACHES AGREEMENT IN PRINCIPLE

WITH BONDHOLDERS ON CONSENT SOLICITATION

GREENWICH, Conn. – September 12, 2005 – United Rentals, Inc. (NYSE: URI) today announced that it has reached an agreement in principle with the steering committee of an ad hoc committee representing holders of the company’s 6½% Senior Notes due 2012, 7¾% Senior Subordinated Notes due 2013 and 7% Senior Subordinated Notes due 2014 (collectively the “Nonconvertible Notes”) and with representatives of an ad hoc group representing holders of the company’s 1 7/8% Convertible Senior Subordinated Notes due 2023 (the “Convertible Notes”) on improved terms to the consent solicitations relating to the company’s outstanding notes and QUIPs securities. The company has been advised that the ad hoc committee representing the Nonconvertible Noteholders consists of approximately 60 financial institutions that collectively hold an aggregate of more than $1.4 billion of the three issues of the Nonconvertible Notes and more than 50% of the principal amount of each issue of the Nonconvertible Notes. In addition, the representatives of the ad hoc group of Convertible Noteholders have advised the company that the members of their group collectively own more than 50% of the outstanding principal amount of the Convertible Notes. As previously disclosed, the proposed amendments would, among other things, allow the company up until March 31, 2006 to regain compliance with the requirement to make timely SEC filings.

Based on the understanding with the representatives of the various bondholder groups, the company is improving the terms of its offer to holders, as follows:

• for the company’s 6½% Senior Notes due 2012, 7¾% Senior Subordinated Notes due 2013 and 7% Senior Subordinated Notes due 2014, the company will pay a consent fee of $16.25 per $1,000 principal amount of notes for which consent is provided;

• for the QUIPs securities, the company will pay a comparable consent fee of $0.8125 per $50 of liquidation preference of such securities for which consent is provided; and

• for the company’s 1 7/8% Convertible Senior Subordinated Notes due 2023, the conversion rate of the Convertible Notes will be increased from 38.9520 to 44.9438 shares of United Rentals’ common stock for each $1,000 principal amount of Convertible Notes.

The company will also provide certain items of unaudited interim operating financial information on a monthly and quarterly basis during the term of the waiver, including revenues, capital expenditures, cash flow from operations, liquidity, and outstanding debt.

Approval of the proposed amendments and waiver will require the consent of holders of not less than a majority of the principal amount of each issue of the company’s outstanding Nonconvertible Notes, Convertible Notes and QUIPs securities.

Wayland Hicks, chief executive officer said, “We are pleased to have reached this understanding with representatives of the various bondholder groups. We continue to focus on resolving expeditiously issues associated with the SEC inquiry and driving strong operating performance.”

The company is extending the expiration date for the consent solicitations to 5:00 p.m., New York City time, on Monday, September 19, 2005.

The solicitations are subject to certain conditions, and present certain risks for holders who consent, as set forth more fully in the consent solicitation statements. These documents contain important information, and holders should read them carefully before making any decision. This announcement is not a solicitation of consents with respect to any securities.
