                         Report of Independent Auditors

To Participants and Administrator of
   United Rentals, Inc. Acquisition Plan

We have audited the accompanying statements of net assets available for benefits
of United Rentals, Inc. Acquisition Plan as of December 31, 2001 and 2000, and
the related statements of changes in net assets available for benefits for the
years then ended. These financial statements are the responsibility of the
Plan's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan at
December 31, 2001 and 2000, and the changes in its net assets available for
benefits for the years then ended, in conformity with accounting principles
generally accepted in the United States.

Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying supplemental schedule of assets
(held at end of year) as of December 31, 2001, is presented for purposes of
additional analysis and is not a required part of the financial statements but
is supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. This supplemental schedule is the responsibility of the
Plan's management. The supplemental schedule has been subjected to the auditing
procedures applied in our audits of the financial statements and, in our
opinion, is fairly stated in all material respects in relation to the financial
statements taken as a whole.

1.  Plan Description

The following description of the United Rentals, Inc. Acquisition Plan (the
"Plan") provides only general information. Participants should refer to the Plan
document for a more complete description of the Plan's provisions.

General

The Plan is a defined contribution, discretionary profit sharing plan which was
established by United Rentals, Inc. (the "Company") on April 1, 1999. An
individual who was an employee of a prior employer acquired by the Company shall
become a participant of the Plan on the date that their assets from the prior
employer plan are transferred to the Plan.

On August 1, 2000, the Plan's trustee was changed from Merrill Lynch Trust
Company, Inc. to T. Rowe Price Trust Company.

Contributions

Participants do not contribute any portion of their salary to the Plan. A
participant may contribute amounts representing distributions from other
qualified defined benefit or defined contribution plans.

The Company may contribute a discretionary amount, if any, to the Plan
determined annually by the Board of Directors of the Company. The Company did
not make any contributions to the Plan in 2001 and 2000.

Participant Accounts

Each participant account is credited with the participant's share of Company
discretionary contributions, if any, assets transferred to this Plan from the
participant's prior employer plan, the participant's share of the net earnings
or losses on the investments of the assets of the Plan, distributions from the
participant's account, and any expenses or liabilities charged to the
participant's account.

                                                                               4

1.  Plan Description (continued)

Vesting

Participants in the Plan are fully vested in their accounts upon the transfer of
their assets into the Plan.

Investment Options

All of the Plan's investment options are fully participant directed.

Participant Loans

Participants may borrow from their fund accounts a minimum of $1,000 up to a
maximum equal to the lesser of $50,000 or 50% of their vested account balance.
Loan terms range from one to five years for personal loans and up to a
reasonable period of time as established by the Plan Administrator for the
purchase of a primary residence. The loans are secured by the vested balance in
the participant's account and bear interest at a rate determined by the Plan
Administrator. Principal and interest are paid ratably through payroll
deductions.

Payment of Benefits

On termination of service, death, disability or retirement a participant may
receive a lump-sum amount equal to the vested value of his or her account.

Administrative Expenses

All of the Plan's administrative expenses are paid by the Company, except for
investment related expenses which are charged directly to the participants'
accounts.

Plan Termination

Although it has not expressed any intent to do so, the Company has the right
under the Plan to discontinue its contributions at any time and terminate the
Plan subject to the provisions of Employee Retirement Income Security Act of
1974.

                                                                               5

2.  Summary of Significant Accounting Policies

Basis of Accounting

Investments

The Plans investments are stated at fair value. Participant loans are valued at
their outstanding principal balances, which approximate fair value.

Use of Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from these estimates.

3.  Income Tax Status

The Plan has applied for but not received a determination letter from the
Internal Revenue Service stating that the Plan is qualified under Section 401(a)
of the Internal Revenue Code (the "Code"). The Company has indicated that it
will take the necessary steps, if any, to maintain the Plan's qualified status.

                                                                               6
