     Not Applicable.

     The consolidated financial statements of United Rentals, Inc. appearing in
United Rentals, Inc.'s Annual Report (Form 10-K) for the year ended December 31,

Item 6. Indemnification of Directors and Officers.

     The Certificate of Incorporation (the "Certificate") of the Company
provides that a director will not be personally liable to the Company or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability (i) for any breach of the director's

                                      II-1



duty of loyalty to the corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the Delaware General Corporation
Law (the "Delaware Law"), which concerns unlawful payments of dividends, stock
purchases or redemptions, or (iv) for any transaction from which the director
derived an improper personal benefit. If the Delaware Law is subsequently
amended to permit further limitation of the personal liability of directors, the
liability of a director of the Company will be eliminated or limited to the
fullest extent permitted by the Delaware Law as amended.

     The Company, as a Delaware corporation, is empowered by Section 145 of the
Delaware Law, subject to the procedures and limitation stated therein, to
indemnify any person against expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by him in
connection with any threatened, pending or completed action, suit or proceeding
in which such person is made a party by reason of his being or having been a
director, officer, employee or agent of the Company. The statute provides that
indemnification pursuant to its provisions is not exclusive of other rights of
indemnification to which a person may be entitled under any by-law, agreement,
vote of stockholders or disinterested directors, or otherwise. The Company has
entered into indemnification agreements with its directors and officers. In
general, these agreements require the Company to indemnify each of such persons
against expenses, judgments, fines, settlements and other liabilities incurred
in connection with any proceeding (including a derivative action) to which such
person may be made a party by reason of the fact that such person is or was a
director, officer or employee of the Company or guaranteed any obligations of
the Company, provided that the right of an indemnitee to receive indemnification
is subject to the following limitations: (i) an indemnitee is not entitled to
indemnification unless he acted in good faith and in a manner that he reasonably
believed to be in or not opposed to the best interests of the Company, and, with
respect to any criminal action or proceeding, had no reasonable cause to believe
such conduct was unlawful and (ii) in the case of a derivative action, an
indemnitee is not entitled to indemnification in the event that he is judged in
a final non-appealable decision of a court of competent jurisdiction to be
liable to the Company due to willful misconduct in the performance of his duties
to the Company (unless and only to the extent that the court determines that the
indemnitee is fairly and reasonably entitled to indemnification).

     Pursuant to Section 145 of the Delaware Law, the Company has purchased
insurance on behalf of its directors and officers against any liability asserted
against or incurred by them in such capacity or arising out of their status as
such.

Item 9. Undertakings

       (a)  The undersigned Registrant hereby undertakes:

       (1)  To file, during any period in which offers or sales are being
            made, a post-effective amendment to this Registration Statement:

            (i) To include any prospectus required by Section 10(a)(3) of the
            Securities Act of 1933;

            (ii)To reflect in the prospectus any facts or events arising after
            the effective date of the Registration Statement (or the most
            recent post-effective amendment thereof) which, individually or in
            the aggregate, represent a fundamental change in the information
            set forth in the Registration Statement;

            (iii) To include any material information with respect to the plan
            of distribution not previously disclosed in the Registration
            Statement or any material change to such information in the
            Registration Statement;

       provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
       apply if the information required to be included in a post-effective
       amendment by those paragraphs is contained in periodic reports filed by
       the Registrant pursuant to Section 13 or 15(d) of the Securities
       Exchange Act of 1934 that are incorporated by reference in the
       Registration Statement.

                                      II-3



     (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
Registration Statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities and Exchange
Act of 1934) that is incorporated by reference in the Registration Statement
shall be deemed to be a new Registration Statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

     (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

                              UNITED RENTALS, INC.

     We have the largest fleet of rental equipment in the world, with over
500,000 units having an original purchase price of approximately $3.5 billion.
Our fleet includes:

          handling equipment, compressors, pumps and generators;

Competitive Advantages

     We believe that we benefit from the following competitive advantages:

     Large and Diverse Rental Fleet. Our rental fleet is the largest and most
comprehensive in the industry, which allows us to:

     o    attract customers by providing "one-stop" shopping;

     o    serve a diverse customer base and reduce our dependence on any
          particular customer or group of customers; and

     o    serve customers that require substantial quantities or wide varieties
          of equipment.

     Significant Purchasing Power. We purchase large amounts of equipment,
merchandise and other items, which enables us to negotiate favorable pricing,
warranty and other terms with our vendors. Our purchasing power is further
increased by our ongoing efforts to consolidate our vendor base. For example, we
reduced the number of our primary equipment suppliers from 111



                                       3


to 28 in 2000. This reduction allowed us to lower our equipment purchase costs
by approximately $150 million in 2000 and should enable us to save additional
amounts in 2001. We expect to realize additional savings by consolidating our
merchandise suppliers and negotiating more favorable warranty terms with key
vendors.

     Operating Efficiencies. We generally group our branches into clusters of 10
to 30 locations that are in the same geographic area. Our information technology
systems allow each branch to access all available equipment within a cluster. We
believe that our cluster strategy produces significant operating efficiencies by
enabling us to: (1) market equipment through all branches within a cluster, (2)
cross-market equipment specialties of different branches within each cluster,
and (3) reduce costs by consolidating functions that are common to our 755
branches, such as payroll, accounts payable and credit and collection, into 26
credit offices and three service centers. In the first quarter of 2001,
approximately 9.8% of our rental revenue was attributable to equipment sharing
among branches.

     Geographic and Customer Diversity. We have more than 750 branches in 47
states, seven Canadian provinces and Mexico and served more than 1.2 million
customers in 2000. Our customers are diverse, ranging from Fortune 500 companies
to small companies and homeowners, and in 2000 our top ten customers accounted
for approximately 2% of our revenues. We believe that our geographic and
customer diversity provide us with many advantages including: (1) enabling us to
better serve National Account customers with multiple locations, (2) helping us
achieve favorable resale prices by allowing us to access used equipment resale
markets across the country, (3) reducing our dependence on any particular
customer and (4) reducing the impact that fluctuations in regional economic
conditions have on our overall financial performance.

     Strong and Motivated Branch Management. Each of our branches has a
full-time branch manager who is supervised by one of our 64 district managers
and nine regional vice presidents. We believe that our managers are among the
most knowledgeable and experienced in the industry, and we empower them--within
budgetary guidelines--to make day-to-day decisions concerning staffing, pricing,
equipment purchasing and other branch matters. Management closely tracks branch,
district and regional performance with extensive systems and controls, including
performance benchmarks and detailed monthly operating reviews. We promote
equipment sharing among branches by linking the compensation of branch managers
and other personnel to their branch's financial performance and return on
assets.

     Information Technology Systems. Our information technology systems
facilitate our ability to make rapid and informed decisions, respond quickly to
changing market conditions, and share equipment among branches. These systems
allow: (1) management to obtain a wide range of operating and financial data,
(2) branch personnel to access and manage branch level data, such as customer
requirements, equipment availability and maintenance histories, and (3)
customers to access their accounts online. These systems promote equipment
sharing among branches by enabling branch personnel to locate needed equipment
within a geographic region, determine its closest location and arrange for
delivery to a customer's work site. We have an in-house team of approximately
100 information technology specialists that supports our systems and extends
them to new locations.

     National Account Program. Our National Account sales force is dedicated to
establishing and expanding relationships with larger companies, particularly
those with a national or multi-regional presence. We offer our National Account
customers the benefits of a


                                       4


consistent level of service across North America and a single point of contact
for all their equipment needs. Our National Account team currently includes 39
professionals serving over 1,400 National Account customers, including more than
200 new accounts added in the first quarter of 2001. We estimate that our
revenues from National Account customers will increase to approximately $350.0
million in 2001 from $245.0 million in 2000.

     Risk Management and Safety Programs. We place great emphasis on risk
reduction and safety and believe that we have one of the most comprehensive risk
management and safety programs in the industry. Our risk management department
is staffed by 43 experienced professionals and is responsible for implementing
our safety programs and procedures, developing our employee and customer
training programs, and managing any claims against us.

Industry Background

     The U.S. equipment rental industry has grown from approximately $6.5
billion in annual rental revenues in 1990 to over $25 billion in 2000,
representing a compound annual growth rate of approximately 14.5%. This
information is based on data provided by Manfredi & Associates, Inc., a leading
industry consultant. We believe that the principal driver of growth in the
equipment rental industry, in addition to general economic expansion, has been
the increasing recognition by equipment users of the many advantages that
equipment rental may offer compared with ownership. They recognize that by
renting they can:

     o    avoid the large capital investment required for equipment purchases;

     o    access a broad selection of equipment and select the equipment best
          suited for each particular job;

     o    reduce storage and maintenance costs; and

     o    access the latest technology without investing in new equipment.

     While the construction industry has to date been the principal user of
rental equipment, industrial companies, utilities and others are increasingly
using rental equipment for plant maintenance, plant turnarounds and other
functions requiring the periodic use of equipment. The market for rental
equipment is also benefiting from increased government funding for
infrastructure projects, such as funding under the U.S. Transportation Equity
Act for the 21st Century ("TEA-21") and the Aviation Investment and Reform Act
for the 21st Century ("AIR-21"). TEA-21 earmarks $175 billion for highway
construction and $42 billion for transit spending over the 1998-2003 fiscal
period, a 40% increase over the prior six-year period. AIR-21 provides for $40
billion in construction spending over three years to support the FAA's airport
improvement programs.

                                  RISK FACTORS

     In addition to the other information in this document, you should carefully
consider the following factors before making an investment decision.

Sensitivity to Changes in Construction and Industrial Activities

     Our equipment is principally used in connection with construction and
industrial activities. Consequently, a downturn in construction or industrial
activity may lead to a decrease in the demand for our equipment, or depress
rental rates and the sales prices for the equipment we sell. We have identified
below certain of the factors which may cause such a downturn, either temporarily
or long-term:

     o    the recent slow-down of the economy worsens or continues over the
          long-term;

     o    an increase in interest rates; or

     o    adverse weather conditions which may temporarily affect a particular
          region.

     In addition, demand for our traffic control equipment may not reach
projected levels in the event that funding for highway and other construction
projects under government programs, such as the Transportation Equity Act for
the 21st Century ("TEA-21") or the Aviation Investment and Reform Act for the
21st Century ("AIR-21"), does not reach expected levels.

Fluctuations of Operating Results

     We expect that our revenues and operating results may fluctuate from
quarter to quarter or over the longer term due to a number of factors,
including:

     o    seasonal rental patterns of our customers--with rental activity
          tending to be lower in the winter;

     o    our recent acquisition of businesses that specialize in renting
          traffic control equipment, which tend to operate at a loss during the
          first quarter;

     o    the timing of expenditures for new equipment and the disposition of
          used equipment;

     o    changes in demand for our equipment or the prices therefor due to
          changes in economic conditions, competition or other factors;

     o    changes in the interest rates applicable to our floating rate debt;

     o    if we determine that a potential acquisition will not be consummated,
          the need to charge against earnings any expenditures relating to such
          transaction (such as financing commitment fees, merger and acquisition
          advisory fees and professional fees)previously capitalized; and

     o    the possible need, from time to time, to take other write-offs or
          special charges due to a variety of occurrences, such as store
          consolidations or closings or the refinancing of existing
          indebtedness.

Dependence on Additional Capital

     We may require additional capital for, among other purposes, purchasing
rental equipment, completing acquisitions, establishing new rental locations,
and refinancing existing indebtedness. If the cash that we generate from our
business, together with cash that we may


                                       6


borrow under our credit facility, is not sufficient to fund our capital
requirements, we will require additional debt and/or equity financing. We
cannot, however, be certain that any additional financing will be available or,
if available, will be available on terms that are satisfactory to us. If we are
unable to obtain sufficient additional capital in the future, our business could
be adversely affected.

Certain Risks Relating to Acquisitions

     The making of acquisitions entails certain risks, including:

     o    unrecorded liabilities of acquired companies that we fail to discover
          during our due diligence investigations;

     o    difficulty in assimilating the operations and personnel of the
          acquired company with our existing operations;

     o    loss of key employees of the acquired company; and

     o    difficulty maintaining uniform standards, controls, procedures and
          policies.

Dependence on Management

     We are highly dependent upon our senior management team. Consequently, our
business could be adversely affected in the event that we lose the services of
any member of senior management. We do not maintain "key man" life insurance
with respect to members of senior management.

Competition

     The equipment rental industry is highly fragmented and competitive. Our
competitors primarily include small, independent businesses with one or two
rental locations; regional competitors which operate in one or more states;
public companies or divisions of public companies; and equipment vendors and
dealers who both sell and rent equipment directly to customers. We may in the
future encounter increased competition from our existing competitors or from new
companies. In addition, certain equipment manufacturers may commence or increase
their existing efforts relating to renting and selling equipment directly to our
customers or potential customers.

Liability and Insurance

     We are exposed to various possible claims relating to our business. These
possible claims include those relating to (1) personal injury or death caused by
equipment rented or sold by us, (2) motor vehicle accidents involving our
delivery and service personnel and (3) employment related claims. We carry a
broad range of insurance for the protection of our assets and operations.
However, such insurance may not fully protect us for a number of reasons,
including:

     o    our coverage is subject to a deductible of $1 million and limited to a
          maximum of $98 million per occurrence;

     o    we do not maintain coverage for environmental liability (other than
          legally required fuel storage tank coverage), since we believe that
          the cost for such coverage is high relative to the benefit that it
          provides; and


                                       7


     o    certain types of claims, such as claims for punitive damages or for
          damages arising from intentional misconduct, which are often alleged
          in third party lawsuits, might not be covered by our insurance.

     We cannot be certain that insurance will continue to be available to us on
economically reasonable terms, if at all.

Environmental and Safety Regulations

     Our operations are subject to numerous laws governing environmental
protection and occupational health and safety matters. These laws regulate such
issues as wastewater, stormwater, solid and hazardous wastes and materials, and
air quality. Under these laws, we may be liable for, among other things, (1) the
costs of investigating and remediating contamination at our sites as well as
sites to which we sent hazardous wastes for disposal or treatment regardless of
fault and (2) fines and penalties for non-compliance. Our operations generally
do not raise significant environmental risks, but we use hazardous materials to
clean and maintain equipment, dispose of solid and hazardous waste and
wastewater from equipment washing, and store and dispense petroleum products
from underground and above-ground storage tanks located at certain of our
locations.

     Based on the conditions currently known to us, we do not believe that any
pending or likely remediation and compliance costs will have a material adverse
effect on our business. We cannot be certain, however, as to the potential
financial impact on our business if new adverse environmental conditions are
discovered or environmental and safety requirements become more stringent. If we
are required to incur environmental compliance or remediation costs that are not
currently anticipated by us, our business could be adversely affected depending
on the magnitude of the cost.

Risks Related to International Operations

     Our operations outside the United States are subject to risks normally
associated with international operations. These include the need to convert
currencies, which could result in a gain or loss depending on fluctuations in
exchange rates, and the need to comply with foreign laws.

Dependence on Information Technology Systems

     Our ability to monitor and control our operations depends to a large extent
on the proper functioning of our information technology systems. Any disruption
in these systems or the failure of these systems to operate as expected could,
depending on the magnitude and duration of the problem, adversely affect our
business.

Labor Matters

     Certain of our employees are represented by unions and covered by
collective bargaining agreements. If we should experience a prolonged labor
dispute involving a significant number of our employees, our business could be
adversely affected.

Restrictive Covenants

     We are subject to various restrictive financial and operating covenants
under the agreements governing our indebtedness. These covenants limit or
prohibit, among other things, our ability to incur indebtedness, make
prepayments of certain indebtedness, make investments,


                                       8


create liens, make acquisitions, sell assets and engage in mergers and
acquisitions. These covenants could adversely affect our business by
significantly limiting our operating and financial flexibility.

                                 USE OF PROCEEDS

     The shares covered by this prospectus are being offered by certain selling
security holders and not by our company. Consequently, our company will not
receive any proceeds from the sale of these shares.

                            SELLING SECURITY HOLDERS

     We have issued an aggregate of 355,588 shares of our common stock to 93 of
our employees pursuant to our 2001 Stock Plan. These employees may, from time to
time, sell some or all of these shares as described below under "Plan of
Distibution."

                              PLAN OF DISTRIBUTION

     The selling security holders may sell shares:

     o    through the New York Stock Exchange, in the over-the-counter market,
          in privately negotiated transactions or otherwise;

     o    directly to purchasers or through agents, brokers, dealers or
          underwriters; and

     o    at market prices prevailing at the time of sale, at prices related to
          such prevailing market prices, or at negotiated prices.

     If a selling security holder sells shares through agents, brokers, dealers
or underwriters, such agents, brokers, dealers or underwriters may receive
compensation in the form of discounts, commissions or concessions. Such
compensation may be greater than customary compensation.

     To the extent required, we will use our best efforts to file one or more
supplements to this prospectus to describe any material information with respect
to the plan of distribution not previously disclosed in this prospectus or any
material change to such information.

                                  LEGAL MATTERS
