To holders of outstanding vested warrants to purchase shares:

You should read carefully the Warrant Election Form, and these instructions, before you complete it. For the Warrant Election Form to be validly delivered, it must be received by the Depositary at one of the addresses listed above before 2:00 p.m. on July 11, 2008, unless the Offer is extended in which case the deadline for receipt of the Warrant Election Form will be 3 business days prior to the date the Offer expires. Delivery of the Warrant Election Form to another address will not constitute a valid delivery. Deliveries to the Company, the Dealer Managers, the Information Agent or DTC will not be forwarded to the Depositary and will not constitute a valid delivery.

The undersigned acknowledge(s) receipt of the enclosed Offer to Purchase, dated June 17, 2008, and the related Letter of Transmittal in connection with the offer by United Rentals, Inc. (“United Rentals,” the “Company,” “we” or “us”) to purchase up to 27,160,000 shares of its common stock, par value $0.01 per share (the “Common Stock”), including the associated preferred share purchase rights, at a purchase price of not greater than $25.00 nor less than $22.00 per share, net to the seller in cash, less any applicable withholding taxes and without interest, upon the terms and subject to the conditions described in the Offer to Purchase and in the related Letter of Transmittal (which together, as they may be amended or supplemented from time to time, constitute the “Offer”).

You should complete the Warrant Election Form if you wish to conditionally exercise some or all of your outstanding (as of the Expiration Date of the Offer) and vested warrants (“Warrants”) to purchase shares and to tender all the underlying shares (“Warrant Shares”), pursuant to the terms and conditions set forth in the Offer. We are conducting this Offer through a procedure called a “modified Dutch auction.” If you are willing to sell your shares, this procedure allows you to select the price at which you are willing to sell within a price range specified by us. The price range for the Offer is $22.00 to $25.00 per share. We will select the lowest purchase price (the “Purchase Price”) that will allow us to buy 27,160,000 shares or, if a lesser number of shares is properly tendered, all shares that are properly tendered and not properly withdrawn. We will determine the Purchase Price promptly after the Expiration Date. For purposes of determining the Purchase Price, those shares that are tendered by shareholders agreeing to accept the Purchase Price determined in the Offer will be deemed to be tendered at the minimum price of $22.00.

All shares that we purchase will be purchased at the Purchase Price, even if you have selected a lower price, but we will not purchase any shares above the Purchase Price we determine. If you wish to maximize the chance that your shares will be purchased, you should check the box in the Warrant Election Form indicating that you will accept the Purchase Price we determine. If you agree to accept the Purchase Price determined in the Offer, you should understand that this election could result in your shares being purchased at the minimum price of $22.00 per share.

By signing the Warrant Election Form, you agree that if any Warrant Shares you properly tendered are accepted, you will receive a cash payment equal to (a) the number of Warrant Shares that are accepted for purchase, multiplied by (b) the difference between the Purchase Price and the applicable Warrant exercise price(s), less any applicable income, employment and withholding taxes, and you further agree to be bound by the Purchase Price and the terms and conditions set forth herein and in the Offer. You also agree that during the term of the Offer, you will NOT submit any other notice to exercise the warrants you have submitted for tender (and we may refuse to process any such notices) until or unless you withdraw your offer to tender.

By signing the Warrant Election Form, you acknowledge that United Rentals is allowing you to conditionally exercise your Warrants for the purpose of allowing you to tender Warrant Shares in the Offer. Further, by signing the Warrant Election Form, you acknowledge that if United Rentals purchases less than all of your Warrant Shares, your remaining Warrants will not be considered to have been exercised and will remain outstanding. If more than 27,160,000 shares (or such greater number of shares as we may elect to purchase, subject to applicable law) are properly tendered and not properly withdrawn then we will purchase shares in the order of priority specified in the Offer to Purchase, which means that Warrant Shares will be treated as conditionally tendered and we may accept Warrant Shares for purchase by random lot, to the extent feasible. Accordingly, under such circumstances, we may not purchase any of

the Warrant Shares you tender even if you tender them at or below the Purchase Price. See Sections 1 and 6 of the Offer to Purchase.

You acknowledge that the order of the Warrants purchased by United Rentals will be as designated by you in the Warrant Election Form. In addition, you acknowledge that if you do not designate the order in which you wish to have your Warrants exercised, your vested Warrants will be exercised in the order of exercise price starting with the lowest price.

Conditional exercises of Warrants and tenders of Warrant Shares pursuant to the Offer may be withdrawn at any time before 2:00 p.m. New York City time, on July 11, 2008 by submitting a written, telegraphic or facsimile transmission notice of withdrawal, including a social security or other taxpayer identification number, so that it is received by the Depositary at the address indicated above. Any such notice of withdrawal must specify the name and social security number of the Warrant holder who tendered the Warrant Shares to be withdrawn and the number of Warrant Shares to be withdrawn. All questions as to the form and validity (including time of receipt) of notices of withdrawal will be determined by United Rentals, in its sole discretion, which determination shall be final and binding. None of United Rentals, the Depository and any other person shall be obligated to give any notice of any defects or irregularities in any notice of withdrawal and none of them shall incur any liability for failure to give any such notice.

The Warrant Election Form must be received by the Depositary before 2:00 p.m. New York City time, on July 11, 2008. You must sign and complete this form for your direction to be valid.

Note: By signing the Warrant Election Form, you also agree to the following terms and conditions which shall not be construed to limit in any way the terms and conditions set forth in the Offer or the Warrant Election.

None of the Warrants underlying any of the Warrant Shares tendered has an exercise price of $25.00 or greater or has an expiration date prior to July 16, 2008.

2.	Election: I hereby elect as follows with respect to my Warrants:

(choose one)


	o	I wish to conditionally exercise and tender Warrant Shares underlying all of my vested Warrants.

	o	I wish to conditionally exercise and tender Warrant Shares underlying my vested Warrants as listed below. I understand that Warrants will be exercised as accepted in the Offer in the order which I designate below:

5. Warrant for shares; Warrant date ; and per share exercise price of $

Attach additional page if needed.

I acknowledge and agree that if I do not designate the order in which I wish to have my Warrants exercised, my vested Warrants will be exercised in the order of exercise price starting with the lowest price. I further acknowledge and agree that if the Purchase Price determined in accordance with the Offer is equal to or lower than the exercise price of a Warrant, each such Warrant, and the tendered Warrant Share with respect to each such Warrant, shall automatically be deemed not to have been, respectively, exercised or tendered.

Tender Price: By checking one of the following boxes the undersigned hereby tenders those Warrant Shares specified in Section 2 of this Warrant Election Form, at the price checked. This action could result in none of the shares being purchased if the Purchase Price determined by the Company is less than the price checked below. The same Warrant Shares cannot be tendered at more than one price, unless previously withdrawn as provided in Section 4 of the Offer to Purchase. Tenders of Warrant Shares at a price equal to or less than the exercise price of the underlying Warrant shall be void.

The method of delivery of this document is at the election and risk of the undersigned.
