                               PROSPECTUS SUMMARY
 
  You should read the following summary together with the more detailed
information and the financial statements and related notes that are included
elsewhere in this prospectus or in the documents that we incorporate by
reference into this prospectus.
 
                                 UNITED RENTALS
 
  United Rentals is the largest equipment rental company in North America with
440 branch locations in 39 states, Canada and Mexico. We offer for rent over
600 different types of equipment on a daily, weekly or monthly basis and serve
customers that include construction industry participants, industrial companies
and homeowners. We also sell used rental equipment, act as a dealer for many
types of new equipment, and sell related merchandise and parts. In the past
year, we have served over 900,000 customers.
 
  We have one of the most comprehensive and newest equipment rental fleets in
the industry. The types of rental equipment that we offer include a broad range
of light to heavy construction and industrial equipment, such as backhoes,
aerial lifts, skid-steer loaders, forklifts, compressors, pumps and generators,
as well as a variety of smaller tools and equipment. Our equipment fleet has an
original purchase price of approximately $2.2 billion and a weighted average
age of approximately 26 months (based on original purchase price).
 
  We began operations in October 1997 and have grown through a combination of
internal growth and the acquisition of 101 companies (through March 3, 1999).
Our acquisitions include our merger with U.S. Rentals in September 1998. At the
time of the merger, U.S. Rentals was the second largest equipment rental
company in the United States based on 1997 rental revenues.
 
  Our principal executive offices are located at Four Greenwich Office Park,
Greenwich, Connecticut 06830, and our telephone number is (203) 622-3131.
 
                             COMPETITIVE ADVANTAGES
 
  We believe that we benefit from the following competitive advantages:
 
  FULL RANGE OF RENTAL EQUIPMENT. We have one of the largest and most
comprehensive equipment rental fleets in the industry, which enables us to:
 
  .  attract customers by providing the benefit of "one-stop" shopping;
 
  .  serve a diverse customer base, which reduces our dependence on any
     particular customer or group of customers;
 
  .  serve large customers that require assurance that substantial quantities
     of different types of equipment will be available as required on a
     continuing basis; and
 
  .  minimize lost sales due to equipment being unavailable.
 
  OPERATING EFFICIENCIES. We generally group our branches into clusters of 10
to 30 locations that are in the same area. Our management information system
enables each branch to track equipment at any other branch and to access all
available equipment within a cluster. We believe that our cluster strategy
produces significant operating efficiencies by enabling us to:
 
  .  market the equipment within a cluster through multiple branches, rather
     than a single branch, which increases our equipment utilization rate;
 
                                       4
<PAGE>
 
 
  .  cross-market the equipment specialties of different branches within each
     cluster, which increases revenues without increasing marketing expenses;
     and
 
  .  reduce costs by centralizing common functions such as payroll, credit
     and collection, and certain equipment delivery.
 
  SIGNIFICANT PURCHASING POWER. We have significant purchasing power because of
our volume purchases. As a result, we can generally buy new equipment and
related merchandise and parts at prices that are significantly lower than
prices paid by smaller companies. We can also buy many other products and
services--such as insurance, telephone and fuel--at attractive rates.
 
  MANAGEMENT INFORMATION SYSTEM. We have a modern management information system
which facilitates rapid and informed decision-making and enables us to respond
quickly to changing market conditions. The system provides management with a
wide range of real time operating and financial data, including reports on
inventory, receivables, customers, vendors, fleet utilization and price and
sales trends. The system also enables branch personnel to search for needed
equipment throughout a geographic region, determine its closest location and
arrange for delivery to a customer's work site. The system includes software
developed by our Wynne Systems subsidiary, which is the leading provider of
proprietary software for use by equipment rental companies in managing and
operating multiple branch locations. We have an in-house staff of 32 management
information specialists that supports our management information system and
extends it to new locations.
 
  CUSTOMER DIVERSITY. Our customer base is highly diversified and ranges from
Fortune 100 companies to small contractors and homeowners. We estimate that our
top ten customers accounted for approximately 4% of our pro forma revenues
during 1998.
 
  GEOGRAPHIC DIVERSITY. We have branches in 39 states, Canada and Mexico. We
believe that our geographic diversity should reduce the impact that
fluctuations in regional economic conditions have on our overall financial
performance. Our geographic diversity and large network of branch locations
also give us the ability to serve national accounts and access used equipment
re-sale markets across the country.
 
  EXPERIENCED SENIOR MANAGEMENT. Our senior management combines executives who
have extensive operating experience in the equipment rental industry with
executives who have proven track records in other industries. Our senior
management includes former officers of United Waste Systems, Inc., which was a
publicly-traded solid waste management company that successfully executed a
growth strategy combining a disciplined acquisition program, the integration
and optimization of acquired facilities, and internal growth. Our senior
management also includes former executives of U.S. Rentals who have extensive
experience in the equipment rental industry.
 
  STRONG AND MOTIVATED BRANCH MANAGEMENT. Each of our branches has a full-time
branch manager who is supervised by one of our 35 district managers and eight
regional vice presidents. We believe that our branch and district managers, who
average over 20 years of experience in the equipment rental industry, are among
the most knowledgeable and experienced in the industry. We encourage
entrepreneurship at the branch level by giving branch managers a high degree of
autonomy relating to day-to-day operations. For example, each branch manager is
empowered to make decisions--within budgetary guidelines--concerning staffing,
pricing and equipment purchasing. We also promote entrepreneurship at the
branch level, as well as equipment sharing among branches, through our profit
sharing program which directly ties the compensation of branch personnel to
their branch's financial performance and equipment utilization rates. We
balance the autonomy that we grant branch managers with systems through which
senior management closely tracks branch performance. We also share information
across branches so that each branch can measure its operating performance
relative to other branches and benefit from the best practices developed
throughout our organization.

  PROFESSIONAL ACQUISITION TEAM. Our 25-person acquisition team works full-time
on identifying and evaluating acquisition candidates and executing our
acquisition program. The core of this group consists of seasoned acquisition
professionals--most of whom were members of the acquisition team at United
Waste Systems, where they completed over 200 acquisitions. The team also
includes former owners of businesses that we acquired, who have extensive
industry experience and contacts with potential acquisition candidates.
 
                                GROWTH STRATEGY
 
  Our plan for future growth includes the following key elements:
 
  CONTINUE STRONG INTERNAL GROWTH. We are seeking to sustain our strong
internal growth by:
 
  .  expanding and modernizing our equipment fleet;
 
  .  increasing the cross-marketing of our equipment specialties at different
     locations;
 
  .  increasing our advertising--which becomes increasingly cost-effective as
     we grow because the benefits are spread over a larger number of
     branches;
 
  .  expanding our national accounts program--which dedicates a portion of
     our sales force to establishing and expanding relationships with large
     customers that have a national or multi-regional presence; and
 
  .  increasing our rentals to industrial companies by developing a
     comprehensive marketing program specifically aimed at this sector.
 
  EXECUTE DISCIPLINED ACQUISITION PROGRAM. We intend to continue our
disciplined acquisition program. We generally seek to acquire multiple
locations within the regions that we enter, with the goal of creating clusters
of locations that can share various resources, including equipment, marketing
resources, back office functions and certain equipment delivery. We are seeking
to acquire companies of varying sizes, including relatively large companies to
serve as platforms for new regional clusters and smaller companies to
complement existing or anticipated locations. In considering whether to buy a
company, we evaluate a number of factors, including purchase price, anticipated
impact on earnings, the quality of the target's rental equipment and
management, the opportunities to improve operating margins and increase
internal growth at the target, the economic prospects of the region in which
the target is located, the potential for additional acquisitions in the region,
and the competitive landscape in the target's markets.
 
  OPEN NEW RENTAL LOCATIONS. Because most of the businesses that we acquired
grew through developing start-up rental locations, many of our managers have
substantial experience in this area. We intend to leverage this experience by
selectively opening new rental locations in attractive markets where there are
no suitable acquisition targets available or where the economics of a start-up
location are more attractive than buying an existing business.
 
  INCREASE COST SAVINGS. We work to reduce costs by efficiently integrating new
and existing operations, eliminating duplicative costs, centralizing common
functions, consolidating locations that serve the same areas, and using our
purchasing power to negotiate discounts from suppliers.
 
  CONTINUE TO EMPHASIZE MANAGEMENT SYSTEMS AND CONTROLS. We intend to further
strengthen our management systems and controls, which currently include:
 
  .  a 12-person internal audit department that is responsible for ensuring
     that we have adequate financial, operating, and management information
     controls throughout our organization;
 
  .  a team of 6 regional controllers and 17 district controllers that
     monitors each branch for compliance with financial and accounting
     procedures established at corporate headquarters; and
 
  .  a 25-person risk management and safety department that is responsible
     for: (1) developing and implementing safety programs and procedures, (2)
     developing our customer and employee training programs and (3)
     investigating and managing any claims that may be asserted against us.

                              INDUSTRY BACKGROUND
 
INDUSTRY SIZE AND GROWTH
 
  We estimate that the U.S. equipment rental industry (including used and new
equipment sales by rental companies) generates annual revenues in excess of $20
billion. The combined equipment rental revenues of the 100 largest equipment
rental companies have increased at an estimated compound annual rate of
approximately 23% from 1992 through 1997 (based upon 1992 revenues and 1997 pro
forma revenues, giving effect to certain acquisitions completed after the
beginning of 1997, reported by the Rental Equipment Register, an industry trade
publication). In addition to reflecting general economic growth, we believe
that the growth in the equipment rental industry reflects the following trends:
 
      RECOGNITION OF ADVANTAGES OF RENTING. Equipment users are increasingly
  recognizing the many advantages that equipment rental may offer compared
  with ownership. They recognize that by renting they can: (1) avoid the
  large capital investment required for equipment purchases, (2) reduce
  storage and maintenance costs, (3) supplement the equipment that they own
  and thereby increase the range and number of jobs that they can work on,
  (4) access a broad selection of equipment and select the equipment best
  suited for each particular job, (5) obtain equipment as needed and minimize
  the costs associated with idle equipment, and (6) access the latest
  technology without investing in new equipment. These advantages frequently
  allow equipment users to reduce their overall costs by renting, rather than
  buying, the equipment they need.
 
      INCREASE IN RENTALS BY CONTRACTORS. There has been a fundamental shift
  in the way contractors meet their equipment needs. While contractors have
  historically used rental equipment on a temporary basis--to provide for
  peak period capacity, meet specific job requirements or replace broken
  equipment--many contractors are now also using rental equipment on an
  ongoing basis to meet their long-term equipment requirements.
 
  Although growth in the equipment rental industry has to date been largely
driven by the increase in rentals by the construction industry, we believe that
other equipment users may increasingly contribute to future industry growth.
For example, many industrial companies require equipment for operating,
repairing, maintaining and upgrading their facilities, and renting this
equipment will often be more cost-effective than purchasing because typically
this equipment is not used full-time. We believe that the cost and other
advantages of renting, together with the general trend toward the corporate
outsourcing of non-core competencies, may increasingly lead industrial
companies to rent equipment. We also believe that these same considerations may
lead other equipment users--such as municipalities, government agencies and
utilities--to increasingly rent equipment. Because the penetration of these
markets by the equipment rental industry is very low in comparison to its
penetration of the construction market, we believe there is significant
potential for additional growth in these markets.
 
INDUSTRY FRAGMENTATION
 
  The equipment rental industry is highly fragmented. It consists of a small
number of multi-location regional or national operators and a large number of
relatively small, independent businesses that serve discrete local markets.
This fragmentation is reflected in the following data:
 
  .  in 1997, there were only 10 equipment rental companies that had
     equipment rental revenues in excess of $100 million and approximately
     100 equipment rental companies that had equipment rental revenues
     between $5 million and $100 million (based upon rental revenues for 1997
     as reported by the Rental Equipment Register, an industry trade
     publication);
 
  .  we estimate that there are more than 20,000 companies with annual
     equipment rental revenues of less than $5 million; and
 
  .  we estimate that the 100 largest equipment rental companies combined
     have less than a 30% share of the market.
 
  We believe that the fragmented nature of the industry presents substantial
consolidation and growth opportunities for companies with access to capital and
the ability to implement a disciplined acquisition program. We also believe
that our management team's extensive experience in acquiring and effectively
integrating acquisition targets should enable us to capitalize on these
opportunities.

                    SUMMARY OF TERMS OF THE REGISTERED NOTES
 
  This exchange offer applies to $300 million aggregate principal amount of the
unregistered original notes. The terms of the registered notes will be
essentially the same as the unregistered original notes, except that the
registered notes will not contain language restricting their transfer, and some
of the registration rights (under the registration rights agreement) will be
different.
 
Issuer......................  United Rentals (North America), Inc.
 
Notes Offered...............  $300 million of 9 1/4% senior subordinated notes
                              due 2009, which have been registered under the
                              Securities Act of 1933.
 
Maturity....................  January 15, 2009.
 
Interest Payment Dates......  Each January 15 and July 15, commencing July 15,
                              1999.
 
Optional Redemption.........  We may redeem the notes on or after January 15,
                              2004 at the prices specified herein.
 
                              In addition, on or prior to January 15, 2002, we
                              may redeem up to 35% of the notes at the prices
                              specified herein, but only with the net cash
                              proceeds from certain equity offerings of our
                              parent company.
 
Guarantees..................  The notes are unconditionally guaranteed on a
                              senior subordinated basis by our current and
                              future United States subsidiaries.
 
Ranking.....................  The notes are unsecured senior subordinated debt,
                              which means they are subordinated in right of
                              payment to all our existing and future senior
                              debt. The guarantees are unsecured senior
                              subordinated obligations of the guarantors, which
                              means they are subordinated in right of payment
                              to all the existing and future senior debt of the
                              guarantors.
 
                              Our foreign subsidiaries are not guarantors of
                              the notes, which means that the notes are
                              effectively subordinated to all obligations of
                              our foreign subsidiaries.
 
                              As of September 30, 1998 (on a pro forma basis
                              giving effect to acquisitions completed
                              subsequent to such date and the financing
                              thereof), our senior debt was $887.1 million, we
                              had debt of $405.0 million that ranks equally in
                              right of payment with the notes, the guarantors'
                              senior debt was $63.0 million, and our
                              subsidiaries that are not guarantors had
                              obligations of $18.9 million.
 
Change of Control...........  If we undergo certain kinds of change of control
                              described herein, we must offer to repurchase the
                              notes at the prices specified herein.
 
Certain Covenants...........  The indenture governing the notes contains
                              certain covenants, including, among others,
                              limitations on incurring debt, creating liens,
                              selling assets and engaging in mergers or
                              consolidations.

Registration Rights.........  A broker-dealer that purchased unregistered notes
                              for its own account as part of market-making or
                              trading activities, must deliver a prospectus
                              when it sells registered notes. We have agreed in
                              the registration rights agreement to allow these
                              broker-dealers to use this prospectus for such
                              purpose during the 30-day period following
                              consummation of the exchange offer (subject to
                              our right under certain circumstances to restrict
                              your use of this prospectus). We may be required
                              to extend this 30-day period under certain
                              circumstances described herein. After this
                              thirty-day period, the registration rights
                              agreement also requires us, in certain
                              circumstances, to make a filing with the SEC to
                              cover the resale of registered notes by these
                              broker-dealers.
 
Absence of Public Market....  There is currently no trading market for the
                              registered notes. We do not intend to apply for
                              listing of the notes on any national securities
                              exchange or quotation of the notes on the Nasdaq
                              National Market. Goldman, Sachs & Co. has advised
                              us that they currently intend to make a market in
                              the notes, but they are not obligated to do so,
                              and any market-making for the notes may be
                              discontinued at any time without notice.

 SUMMARY HISTORICAL AND UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION
 
GENERAL
 
    The table below presents selected historical and pro forma financial
information for our company. You should read this information together with (1)
the Consolidated Financial Statements and the related notes and Pro Forma
Consolidated Financial Statements and the related notes of our company included
elsewhere in this prospectus or incorporated by reference herein and (2) the
financial statements incorporated by reference herein of certain of the
companies that we acquired.
 
ACCOUNTING FOR ACQUISITIONS
 
    We commenced operations in October 1997 by acquiring six established
equipment rental companies. Thereafter, we completed 91 additional acquisitions
(through February 11, 1999), including a merger with U.S. Rentals, Inc. which
was completed in September 1998. We accounted for three of these acquisitions
(including the U.S. Rentals merger) as "poolings-of-interests," which means
that for accounting and financial reporting purposes the acquired company is
treated as having been combined with us at all times since the inception of he
acquired company. Accordingly, we have restated our financial statements to
include the accounts of two of the companies acquired in these pooling-of-
interests transactions (but have not restated our financial statements for the
third transaction, which was not material and which has been combined with us
effective July 1, 1998). As a result of this restatement, our financial
statements include historical financial information for periods that precede
the date on which we commenced our own operations. (For additional information
concerning this restatement, see Note 3 to the Consolidated Financial
Statements of United Rentals incorporated by reference herein.) We accounted
for our other 94 acquisitions as "purchases," which means that the results of
operations of the acquired company are included in our financial statements
only from the date of acquisition.
 
PRO FORMA DATA
 
    The table below includes the following pro forma data:
 
  .  PRO FORMA INCOME STATEMENT AND OTHER FINANCIAL DATA--intended to show
     for the periods indicated what our business might have looked like had
     each acquisition (other than any pooling-of-interests) completed after
     the beginning of the period (through February 11, 1999) and any related
     acquisition financing been completed on the first day of the period;
 
  .  PRO FORMA BALANCE SHEET DATA--intended to show how certain balance sheet
     data would have looked at September 30, 1998 had each acquisition
     completed after such date (through February 11, 1999) and any related
     acquisition financing been completed on September 30, 1998.
 
  We have provided the pro forma data for your information. However, this data
may not be indicative of (1) the actual results that we would have had during
any period if all acquisitions had been completed as of the beginning of the
period or (2) our future results.

- -------
(1) The Company recorded an extraordinary item (net of income taxes) of $1.5
    million in 1997 and an extraordinary item (net of income taxes) of $21.3
    million in 1998. Such charge in 1997 resulted from the prepayment of
    certain debt by U.S. Rentals. Such charge in 1998 resulted from the early
    extinguishment of certain debt and primarily reflected prepayment penalties
    on certain debt of U.S. Rentals.
(2) U.S. Rentals was taxed as a Subchapter S Corporation until its initial
    public offering in February 1997, and another acquired company was taxed as
    a Subchapter S Corporation until being acquired by the Company in 1998. In
    general, the income or loss of a Subchapter S Corporation is passed through
    to its owners rather than being subjected to taxes at the entity level. Pro
    forma provision for income taxes before extraordinary items and pro forma
    income (loss) before extraordinary items reflect a provision for income
    taxes as if all such companies were liable for federal and state income
    taxes as taxable corporate entities for all periods presented.
(3) EBITDA is defined as net income (excluding (i) non-operating income and
    expense, (ii) a $20.3 million non-recurring charge incurred by U.S. Rentals
    in 1997 arising from the termination of deferred compensation agreements
    with certain executives and (iii) $42.2 million in merger-related expenses
    in 1998 related to the three acquisitions accounted for as poolings-of-
    interests, including the merger with U.S. Rentals) plus interest expense,
    income taxes and depreciation and amortization. EBITDA data is presented to
    provide additional information concerning the Company's ability to meet its
    future debt service obligations and capital expenditure and working capital
    requirements. However, EBITDA is not a measure of financial performance
    under generally accepted accounting principles. Accordingly, EBITDA should
    not be considered an alternative to net income or cash flows as indicators
    of the Company's operating performance or liquidity.
(4) EBITDA margin is defined as EBITDA as a percentage of revenues.
(5) Interest expense excludes the amortization of deferred financing fees.
(6) URI is a wholly owned subsidiary of Holdings. Although not legally
    obligated to do so, URI has made, and expects that it will continue to
    make, cash distributions to Holdings in order to enable Holdings to pay
    dividends on certain preferred securities that were issued by a subsidiary
    trust of Holdings. These distributions are not reflected in URI's interest
    expense.
(7) For purposes of determining the ratio of total debt to EBITDA for the nine
    months ended September 30, 1998, EBITDA is annualized.
(8) For purposes of determining the ratio of earnings to fixed charges, (i)
    earnings consist of income before income taxes and extraordinary items plus
    fixed charges and (ii) fixed charges consist of interest expense,
    amortization of debt issuance costs, and the estimated interest portion of
    rental expense.
(9) The pro forma ratio of earnings to fixed charges gives effect to the
    issuance of the Notes and the application of a portion of the net proceeds
    therefrom to repay outstanding indebtedness, as if such transaction had
    occurred at the beginning of the period.
(10) The supplemental pro forma ratio of earnings to fixed charges gives effect
     to each acquisition completed by the Company after the beginning of the
     period and the financing thereof, as if such transactions had occurred at
     the beginning of the period.

                                 RISK FACTORS
 
  You should carefully consider the following factors and the other
information in this prospectus in connection with this exchange offer and an
investment in the notes.
 
SUBSTANTIAL DEBT
 
  We have incurred substantial debt in connection with our business
acquisitions. As of September 30, 1998, on a pro forma basis giving effect to
acquisitions completed subsequent to such date (through February 11, 1999) and
the financing thereof, we had total debt of $1.4 billion. We will require
substantial capital to finance our continuing growth, and we expect to incur
substantial additional debt from time to time (including borrowing money under
our credit facility) for a variety of purposes, including acquiring additional
businesses, establishing new locations, and purchasing equipment.
 
  The degree to which we have outstanding debt could have important
consequences for holders of the notes, including:
 
  .  a substantial portion of our cash flow will go towards payment of
     principal and interest on our debt, meaning it will not be available for
     other purposes;
 
  .  our ability to obtain additional financing may be constrained due to our
     existing level of debt;
 
  .  a high degree of debt might make us more vulnerable to a downturn in our
     business or the economy in general; and
 
  .  some of our debt is (or might be in the future) subject to variable
     interest rates, which might make us vulnerable to increases in interest
     rates.
 
  Our ability to make scheduled payments of principal and interest on, or to
refinance, our debt (including the notes) depends on our future financial
performance, which, to a certain extent, is subject to economic, competitive,
regulatory and other factors beyond our control. There can be no assurance
that we will have sufficient cash from our operations or other sources to
service our debt (including the notes).
 
SUBORDINATION OF THE NOTES AND GUARANTEES
 
  The notes are general unsecured obligations which are subordinated in right
of payment to the prior payment of all of our current and future senior debt.
Likewise, the guarantees of the notes are general unsecured obligations of the
guarantors which are subordinated in right of payment to the prior payment of
all of their current and future senior debt. Finally, our foreign subsidiaries
are not guarantors of the notes, meaning that the notes are effectively
subordinated to all of their obligations.
 
  The effect of this subordination means that:
 
  .  if we were to undergo a bankruptcy, liquidation, dissolution,
     reorganization or similar proceeding, our assets would be available to
     pay our obligations on the notes only after all of our senior debt was
     paid;
 
  .  if any of the guarantors were to undergo one of those types of
     proceedings, their assets would be available to pay their obligations on
     the guarantees of the notes only after all of their senior debt was
     paid; and
 
  .  if any non-guarantor subsidiary were to undergo one of those types of
     proceedings, its assets would be available to pay the notes only after
     all obligations of the subsidiary were paid.
 
  As of September 30, 1998, on a pro forma basis giving effect to
  acquisitions completed subsequent to such date and the financing thereof:
 
  .  our senior debt was $887.1 million;
 
  .  the guarantors' senior debt was $63.0 million;
 
                                      14
<PAGE>
 
  .  our subsidiaries that are not guarantors had obligations of $18.9
     million; and
 
  .  we had debt of $405.0 million that ranks equally in right of payment
     with the notes.
 
UNSECURED STATUS OF THE NOTES AND GUARANTEES
 
  The indenture governing the notes permits us to incur certain secured debt,
including debt under our credit facility and term loan which are secured by a
lien on substantially all of our assets and the assets of the guarantors.
Because they have this security interest, the lenders under the credit
facility and term loan would have the right to exercise certain remedies, such
as foreclosure, if a default were to occur. Since the notes and the guarantees
of the notes are unsecured, the effect of their security interest gives the
lenders under the credit facility and term loan a prior claim on our assets
and the assets of the guarantors, in addition to the priority that they have
by virtue of the subordination described above.
 
RISKS ASSOCIATED WITH HOLDING COMPANY STRUCTURE
 
  We derive all of our operating income from our subsidiaries and, as of
September 30, 1998, approximately 99% of our consolidated assets were owned by
our subsidiaries. Consequently, our ability to meet our financial obligations,
including our obligations under the notes and other outstanding debt, depends
on the earnings of our subsidiaries and the payment or other distribution to
us of these earnings. Certain provisions of law limit the ability of our
subsidiaries to make payments or other distributions to us, and it is possible
that their ability to do so may be further limited by loan or other agreements
they might enter into in the future.
 
POSSIBLE INABILITY TO REPURCHASE NOTES UPON CHANGE OF CONTROL
 
  Under the terms of the indenture governing the notes, we may be required to
repurchase the notes upon a change of control of our company. However, we
cannot guarantee that we would have sufficient cash to make these required
repurchases.
 
  Furthermore, the terms of our credit facility and term loan prohibit us from
repurchasing the notes, and future agreements relating to senior debt may
contain the same prohibition. If a change of control were to occur while we
were prohibited from repurchasing the notes, we could seek the consent of our
lenders to the repurchases or could seek to refinance the debt containing the
prohibitions. If we failed to get this consent or to refinance the debt, we
would remain prohibited from repurchasing the notes. In that event, our
failure to repurchase the notes would be a default under the indenture
governing the notes which would, in turn, be a default under our credit
facility, term loan and, potentially, other senior debt. Were all of this to
occur, it is likely that payments to holders of the notes would be restricted.
 
FRAUDULENT TRANSFER CONSIDERATIONS
 
  Certain laws enacted to protect creditors against fraudulent conveyances by
borrowers may apply to the guarantors' issuance of the guarantees of the
notes. In certain circumstances, a court could invalidate one or more of the
guarantees or make them subordinate to other claims of the creditors of the
affected guarantors. Were this to occur, there can be no assurance that there
would be sufficient assets remaining to satisfy claims of the holders of the
notes after providing for all prior claims.
 
  Based on financial and other applicable information, we believe that the
notes and the guarantees would not cause a court to take action under any
fraudulent conveyance laws. We cannot, however, be certain that a court would
agree with our conclusion.
 
CONSEQUENCES OF FAILURE TO EXCHANGE ORIGINAL NOTES
 
  Any unregistered original notes that remain outstanding after this exchange
offer will continue to be subject to restrictions on their transfer. After
this exchange offer, holders of unregistered original notes will not (with
limited exceptions) have any further rights under the registration rights
agreement. Any market for unregistered original notes that are not exchanged
could be adversely affected by the conclusion of this exchange offer.
 
                                      15

EXCHANGE OFFER PROCEDURES
 
  Issuance of registered notes in exchange for unregistered original notes
will only occur upon completion of the procedure described in this prospectus
under the heading "The Exchange Offer--Procedures for Tendering." Therefore,
holders of unregistered original notes who wish to exchange them for
registered notes should allow sufficient time for timely completion of the
exchange procedure. We are not obligated to notify you of any failure to
follow the proper procedure.
 
PROSPECTUS DELIVERY REQUIREMENTS APPLICABLE TO PARTICIPATING BROKER-DEALERS
 
  A broker-dealer that purchased unregistered notes for its own account as
part of market-making or trading activities, must deliver a prospectus when it
sells registered notes. Our obligation to make this prospectus available to
broker-dealers is limited. Consequently, we cannot guarantee that a proper
prospectus will be available to broker-dealers wishing to resell their
registered notes.
 
NEED TO MAKE REPRESENTATIONS IN ORDER TO PARTICIPATE IN EXCHANGE OFFER
 
  In order to participate in the exchange offer, you will be required to make
certain representations in a letter of transmittal as described herein.
 
  If any of these representations are falsely made, the notes received in
exchange for your unregistered original notes may be restricted, meaning that
they would not be freely tradable.
 
ABSENCE OF PUBLIC MARKET FOR THE NOTES
 
  There is currently no trading market for the registered notes. We do not
intend to apply for listing of the notes on any national securities exchange
or quotation of the notes on the Nasdaq National Market. Goldman, Sachs & Co.
has advised us that they currently intend to make a market in the notes, but
they are not obligated to do so, and any market-making for the notes may be
discontinued at any time without notice. We cannot guarantee that a market for
the notes will develop.
 
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 demand for our equipment, which could
adversely affect our business. We have identified below certain of the factors
which may cause such a downturn, either temporarily or long-term:
 
  .  a general slow-down of the economy;
 
  .  an increase in interest rates; or
 
  .  adverse weather conditions which may temporarily affect a particular
     region.
 
ACQUIRED COMPANIES NOT HISTORICALLY OPERATED AS A COMBINED BUSINESS
 
  The businesses that we acquired have been in existence an average of 29
years and some have been in existence for more than 50 years. However, these
businesses were not historically managed or operated as a single business.
Although we believe that we can successfully manage and operate the acquired
businesses as a single business, we cannot be certain of this.
 
LIMITED OPERATING HISTORY
 
  We commenced equipment rental operations in October 1997 and have grown
through a combination of internal growth and the acquisition of 101 companies
(through March 3, 1999), including a merger in September
 
                                      16
<PAGE>
 
1998 with U.S. Rentals. Due to the relatively recent commencement of our
operations, we have only a limited history upon which you can base an
assessment of our business and prospects.
 
RISKS RELATING TO GROWTH STRATEGY
 
  Key elements of our growth strategy are to continue to expand through a
combination of internal growth, a disciplined acquisition program and the
opening of new rental locations. We have identified below some of the risks
relating to our growth strategy:
 
  AVAILABILITY OF ACQUISITION TARGETS AND SITES FOR START-UP LOCATIONS. We may
encounter substantial competition in our efforts to acquire additional rental
companies and sites for start-up locations. Such competition could have the
effect of increasing the prices that we will have to pay in order to acquire
such businesses and sites. We cannot guarantee that any additional businesses
or sites that we may wish to acquire will be available to us on terms that are
acceptable to us.
 
  NEED TO INTEGRATE NEW OPERATIONS. Our ability to realize the expected
benefits from completed and future acquisitions depends, in large part, on our
ability to integrate the new operations with our existing operations in a
timely and effective manner. Accordingly, we devote substantial efforts to the
integration of new operations. We cannot, however, guarantee that these
efforts will always be successful. In addition, under certain circumstances,
these efforts could adversely affect our existing operations.
 
  DEBT COVENANTS. Certain of the agreements governing our outstanding
indebtedness provide that we may not make acquisitions unless certain
financial conditions are satisfied or the consent of the lenders is obtained.
Our ability to grow through acquisitions may be constrained as a result of
these provisions.
 
  CERTAIN RISKS RELATED TO START-UP LOCATIONS. We expect that start-up
locations may initially have a negative impact on our results of operations
and margins for a number of reasons, including that (1) we will incur
significant start-up expenses in connection with establishing each start-up
location and (2) it will generally take some time following the commencement
of operations for a start-up location to become profitable. Although we
believe that start-ups can generate long-term growth, we cannot guarantee that
any start-up location will become profitable within any specific time period,
if at all.
 
DEPENDENCE ON ADDITIONAL CAPITAL TO FINANCE GROWTH
 
  We will require substantial capital in order to execute our growth strategy.
We will require capital for, among other purposes, completing acquisitions,
establishing new rental locations, and acquiring rental equipment. If the cash
that we generate from our business, together with cash that we may 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 ability to implement
our growth strategy could be limited.
 
POSSIBLE UNDISCOVERED LIABILITIES OF ACQUIRED COMPANIES
 
  Prior to making an acquisition, we seek to assess the liabilities of the
target company that we will become responsible for as a result of the
acquisition. Nevertheless, we may fail to discover certain of such
liabilities. We seek to reduce our risk relating to these possible hidden
liabilities by generally obtaining the agreement of the seller to reimburse us
in the event that we discover any material hidden liabilities. However, this
type of agreement, if obtained, may not fully protect us against hidden
liabilities because (1) the seller's obligation to reimburse us is generally
limited in duration and/or amount and (2) the seller may not have sufficient
financial resources to reimburse us. Furthermore, when we acquire a public
company (such as when we acquired U.S. Rentals) there is no seller from which
to obtain this type of agreement.
 
 
                                      17
<PAGE>
 
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. Furthermore, if we lose the services of
certain members of senior management, it is an event of default under the
agreements governing our credit facility and certain of our other
indebtedness, unless we appoint replacement officers satisfactory to the
lenders within 30 days. 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.
 
QUARTERLY FLUCTUATIONS OF OPERATING RESULTS
 
  We expect that our revenues and operating results may fluctuate from quarter
to quarter due to a number of factors, including:
 
  .  seasonal rental patterns of our customers--with rental activity tending
     to be lower in the winter;
 
  .  changes in general economic conditions in our markets, including changes
     in construction and industrial activities;
 
  .  the timing of acquisitions, new location openings, and related
     expenditures;
 
  .  the effect of the integration of acquired businesses and start-up
     locations;
 
  .  the timing of expenditures for new equipment and the disposition of used
     equipment; and
 
  .  price changes in response to competitive factors.
 
LIABILITY AND INSURANCE
 
  We are exposed to various possible claims relating to our business. These
include claims 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:
 
  .  our coverage is subject to a deductible of $0.5 million and limited to a
     maximum of $97 million per occurrence;
 
  .  we do not maintain coverage for environmental liability, since we
     believe that the cost for such coverage is high relative to the benefit
     that it provides; and
 
  .  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.
 
                                      18

ENVIRONMENTAL AND SAFETY REGULATIONS
 
  There are numerous federal, state and local laws and regulations governing
environmental protection and occupational health and safety matters. These
include laws and regulations that govern wastewater discharges, the use,
treatment, storage and disposal of solid and hazardous wastes and materials,
air quality and the remediation of contamination associated with the release
of hazardous substances. Under these laws, an owner or lessee of real estate
may be liable for, among other things, (1) the costs of removal or remediation
of hazardous or toxic substances located on, in, or emanating from, the real
estate, as well as related costs of investigation and property damage and
substantial penalties, and (2) environmental contamination at facilities where
its waste is or has been disposed. These laws often impose liability whether
or not the owner or lessee knew of the presence of the hazardous or toxic
substances and whether or not the owner or lessee was responsible for these
substances. Our activities that are or may be affected by these laws include
our use of hazardous materials to clean and maintain equipment and our
disposal of solid and hazardous waste and wastewater from equipment washing.
We also dispense petroleum products from underground and above-ground storage
tanks located at certain rental locations, and at times we must remove or
upgrade tanks to comply with applicable laws. Furthermore, we have acquired or
lease certain locations which have or may have been contaminated by leakage
from underground tanks or other sources and are in the process of assessing
the nature of the required remediation. Based on the conditions currently
known to us, we believe that any unreserved environmental remediation and
compliance costs required with respect to those conditions will not have a
material adverse effect on our business. However, we cannot be certain that we
will not identify adverse environmental conditions that are not currently
known to us, that all potential releases from underground storage tanks
removed in the past have been identified, or that environmental and safety
requirements will not become more stringent or be interpreted and applied more
stringently in the future. 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.
 
YEAR 2000 ISSUES
 
  Our software vendors have informed us that our recently-installed management
information system is year 2000 compliant. We have, therefore, not developed
any contingency plans relating to year 2000 issues and have not budgeted any
funds for year 2000 issues. Although we believe that our system is year 2000
compliant, unanticipated year 2000 problems may arise which, depending on the
nature and magnitude of the problem, could adversely affect our business.
Furthermore, year 2000 problems involving third parties may have a negative
impact on our customers or suppliers, the general economy or on the ability of
businesses generally to receive essential services (such as
telecommunications, banking services, etc.). Any such problem could adversely
affect our business. We are unable at this time to assess the possible impact
on our business of year 2000 problems involving any third party.
 
RESTRICTIVE COVENANTS
 
  The indenture governing the notes and other agreements governing our
existing long-term indebtedness, contain, and future agreements governing our
long-term indebtedness may also contain, certain restrictive financial and
operating covenants which affect, and in many respects significantly limit or
prohibit, among other things, our ability to incur indebtedness, make
prepayments of certain indebtedness, make investments, create liens, make
acquisitions, sell assets and engage in mergers and consolidations. These
covenants may significantly limit our operating and financial flexibility.

                             CORPORATE INFORMATION
 
  United Rentals (North America), Inc. ("URI") is a wholly owned subsidiary of
United Rentals, Inc. ("Holdings"). URI was incorporated in August 1997,
initially capitalized in September 1997 and commenced equipment rental
operations in October 1997. Holdings was incorporated in July 1998 and became
the parent company of URI on August 5, 1998, in connection with a
reorganization of URI's corporate structure that was effected in order to
facilitate certain financings. As part of such reorganization, the outstanding
common stock of URI was converted, on a share for share basis, into common
stock of Holdings and the common stock of Holdings commenced trading on the
New York Stock Exchange instead of the common stock of URI. Prior to such
reorganization, the name of United Rentals (North America), Inc. was United
Rentals, Inc. Unless otherwise indicated or the context otherwise clearly
requires, (i) the terms "United Rentals" and "Holdings" refer to United
Rentals, Inc., (ii) the term "URI" refers to United Rentals (North America),
Inc. and not its subsidiaries, (iii) the term "the Company" refers to URI and
its subsidiaries, and (iv) the term "Common Stock" refers to the common stock
of URI, with respect to periods prior to such reorganization, and to the
common stock of Holdings, with respect to periods thereafter.

                              THE EXCHANGE OFFER
 
  The following summary of certain terms of the Exchange Offer is qualified in
its entirety by reference to the full text of the documents underlying the
Exchange Offer, including the Letter of Transmittal and the Registration
Rights Agreement, copies of which are filed as exhibits to the Registration
Statement of which this Prospectus is a part.
 
  Participation in the Exchange Offer is voluntary, and holders of
unregistered original notes (the "Original Notes") should carefully consider
whether to accept. Holders of Original Notes are urged to consult their
financial and tax advisors in making their decision on what action to take.
 
PURPOSE OF THE EXCHANGE OFFER; EFFECT ON HOLDERS OF ORIGINAL NOTES
 
  The Exchange Offer is being made in order to satisfy certain of URI's
obligations under the Registration Rights Agreement. See "Registration Rights
Agreement."
 
  Upon consummation of the Exchange Offer, the holders of Original Notes will
not have any further registration rights under the Registration Rights
Agreement (subject to limited exceptions as described under "Registration
Right Agreement--Shelf Registration Statement"). Holders of the Original Notes
who do not tender their Original Notes in the Exchange Offer will continue to
hold such Original Notes and will be entitled to all the rights and will be
subject to all the limitations applicable thereto under the Indenture. All
Original Notes that remain outstanding upon consummation of the Exchange Offer
will continue to be subject to the restrictions on transfer provided for in
the Original Notes and the Indenture. In general, the Original Notes may not
be offered or sold unless registered under the Securities Act of 1933 (the
"Securities Act"), except pursuant to an exemption from, or in a transaction
not subject to, the registration requirements of the Securities Act. To the
extent that the Original Notes are tendered and accepted in the Exchange
Offer, the trading market for untendered Original Notes could be adversely
affected.
 
REQUIRED REPRESENTATIONS
 
  In connection with any tender of Original Notes pursuant to the Exchange
Offer, the Book-Entry Holder (as defined below) of such Original Notes will be
required to make certain representations in the Letter of Transmittal,
including that (i) it is not an affiliate of URI, (ii) it is not a broker-
dealer that purchased such Original Notes directly from URI, (iii) any
registered notes that it acquires in the Exchange Offer (the "Exchange Notes")
will be acquired by it in the ordinary course of its business and (iv) it has
no arrangement with any person to participate in the distribution of the
Exchange Notes; provided, however, that if the Book-Entry Holder is a broker-
dealer that wishes to tender Original Notes that were acquired by it for its
own account as a result of market-making activities or other trading
activities, it may represent, in lieu of the representation set forth in
clause (iv), that it has no arrangement or understanding with URI, or any
affiliate of URI, to participate in the distribution of the Exchange Notes. In
addition, a Book-Entry Holder that holds any Original Notes as nominee will be
required to confirm that the beneficial owner for which it is holding such
Original Notes has made the representations provided for in the preceding
sentence.
 
  The term "Book-Entry Holder" with respect to any Notes means the participant
in the system of The Depository Trust Company ("DTC") that is listed as the
holder of such Notes in the records maintained by DTC.
 
RESALE OF EXCHANGE NOTES
 
  Based on interpretations by the staff of the Securities and Exchange
Commission (the "Commission") set forth in no-action letters issued to third
parties, URI believes that (except as provided in the following two
paragraphs) the Exchange Notes issued pursuant to the Exchange Offer may be
offered for resale, resold or otherwise transferred by any Holder thereof
(other than an affiliate of URI) without compliance with the registration and
prospectus delivery provisions of the Securities Act (subject to the
representations set forth under "--Required Representations" being made and
being accurate).
 
                                      21
<PAGE>
 
  Any broker-dealer that receives Exchange Notes in exchange for Original
Notes that were acquired by it for its own account as a result of market-
making activities or other trading activities, must deliver a prospectus
meeting the requirements of the Securities Act in connection with any resales
by it of any such Exchange Notes. This Prospectus, as it may be amended or
supplemented from time to time, may, if permitted by URI, be used by a broker-
dealer in order to satisfy such prospectus delivery requirements. URI has
agreed in the Registration Rights Agreement that, for a period of 30 days
following consummation of the Exchange Offer (subject to extension under
certain circumstances described under "Registration Rights Agreement"), it
will make this Prospectus available to any broker-dealer for use in connection
with any such resale (subject to the right of URI to restrict the use of this
Prospectus under certain circumstances). Each broker-dealer that participates
in the Exchange Offer will be required to confirm that it will comply with the
prospectus delivery requirements described above. A broker-dealer that
delivers a prospectus in connection with the resale of any Exchange Notes will
be subject to certain of the civil liability provisions under the Securities
Act. See "Registration Rights Agreement" and "Plan of Distribution."
 
  In the event that any of the required representations set forth under "--
Required Representations" is not true with respect to a Holder that receives
Exchange Notes pursuant to the Exchange Offer, the Exchange Notes received by
such Holder may be deemed to be restricted securities and, if so, such
Exchange Notes may not be offered or sold unless registered under the
Securities Act, except pursuant to an exemption from, or in a transaction not
subject to, the registration requirements of the Securities Act.
 
  The conclusions set forth in the preceding three paragraphs are based on
interpretations by the staff of the Commission set forth in no-action letters
issued to third parties. URI does not intend to seek its own no-action letter
with respect to the Exchange Offer and there is no assurance that the Staff of
the Commission would make a similar determination with respect to the Exchange
Offer as it has in such no-action letters to third parties.
 
TERMS OF THE EXCHANGE OFFER
 
  Upon the terms and subject to the conditions set forth in this Prospectus
and in the accompanying Letter of Transmittal, URI will accept for exchange
all Original Notes properly tendered and not withdrawn prior to 5:00 p.m., New
York City time, on the Expiration Date (as defined herein). URI will issue
$1,000 principal amount of Exchange Notes in exchange for each $1,000
principal amount of outstanding Original Notes accepted in the Exchange Offer.
Holders may tender some or all of their Original Notes pursuant to the
Exchange Offer in denominations of $1,000 and integral multiples thereof. The
Exchange Offer is not conditioned upon any minimum aggregate principal amount
of Original Notes being tendered.
 
  The terms of the Exchange Notes will be the same in all material respects as
the Original Notes except that (i) the Exchange Notes will be registered under
the Securities Act, and, therefore, will not bear legends restricting the
transfer thereof and (ii) certain of the registration rights, under the
Registration Rights Agreement, relating to the Exchange Notes are different
than those relating to the Original Notes and, therefore, the defaults under
the Registration Rights Agreement that may require URI to pay additional
interest will be different for the Exchange Notes and the Original Notes. See
"Registration Rights Agreement--Certain Provisions Relating to Additional
Interest." The Exchange Notes will evidence the same debt as the Original
Notes and both series of Notes will be entitled to the benefits of the
Indenture and treated as a single class of debt securities.
 
  In connection with the issuance of the Original Notes, URI arranged for the
Original Notes to be issued and transferable in book-entry form through the
facilities of DTC, acting as depositary. The Exchange Notes will also be
issuable and transferable in book-entry form through DTC. See "Description of
the Notes--Book Entry; Delivery and Form."
 
  URI shall be deemed to have accepted validly tendered Original Notes when,
as and if URI has given oral or written notice thereof to the Exchange Agent
(as defined herein). The Exchange Agent will act as agent for the tendering
Holders of Original Notes for the purposes of receiving the Exchange Notes
from URI and delivering Exchange Notes to such Holders. URI's obligation to
accept Original Notes for exchange pursuant to the Exchange Offer is subject
to certain customary conditions as set forth under "--Conditions."
 
                                      22
<PAGE>
 
  If any tendered Original Notes are not accepted for exchange because of an
invalid tender or the occurrence of certain other events set forth herein,
such unaccepted Original Notes will be returned, without expense, to the
tendering Holder thereof as promptly as practicable after the Expiration Date.
 
  Holders of Original Notes who tender pursuant to the Exchange Offer will not
be required to pay brokerage commissions or fees or, subject to the
instructions in the Letter of Transmittal, transfer taxes with respect to the
exchange of Original Notes pursuant to the Exchange Offer. URI will pay all
charges and expenses, other than certain applicable taxes, in connection with
the Exchange Offer. See "--Solicitation of Tenders; Fees and Expenses."
 
  Holders do not have appraisal or dissenters' rights under the Delaware
General Corporation Law or under the Indenture in connection with the Exchange
Offer. URI intends to conduct the Exchange Offer in accordance with the
applicable requirements of Regulation 14E under the Securities Exchange Act of
1934, as amended (the "Exchange Act").
 
  NEITHER THE BOARD OF DIRECTORS OF THE COMPANY NOR THE COMPANY MAKES ANY
RECOMMENDATION TO HOLDERS OF ORIGINAL NOTES AS TO WHETHER TO TENDER OR REFRAIN
FROM TENDERING ALL OR ANY PORTION OF THEIR ORIGINAL NOTES PURSUANT TO THE
EXCHANGE OFFER. MOREOVER, NO ONE HAS BEEN AUTHORIZED TO MAKE ANY SUCH
RECOMMENDATION. HOLDERS OF ORIGINAL NOTES MUST MAKE THEIR OWN DECISION WHETHER
TO TENDER PURSUANT TO THE EXCHANGE OFFER AND, IF SO, THE AGGREGATE AMOUNT OF
ORIGINAL NOTES TO TENDER, AFTER READING THIS PROSPECTUS AND THE LETTER OF
TRANSMITTAL AND CONSULTING WITH THEIR ADVISORS, IF ANY, BASED ON THEIR OWN
FINANCIAL POSITION AND REQUIREMENTS.
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
  The Exchange Offer will remain open for acceptance for a period of not less
than 20 business days after the date notice of the Exchange Offer is mailed to
holders of the Original Notes (or longer if required by applicable law). The
Expiration Date will be 5:00 p.m., New York City time, on       , 1999, unless
URI, in its sole discretion, extends the Exchange Offer, in which case the
Expiration Date will be the latest business day to which the Exchange Offer is
extended. In order to extend the Expiration Date, URI will notify the Exchange
Agent of any extension by oral or written notice and will mail to the record
holders an announcement thereof, each prior to 9:00 a.m., New York City time,
on the next business day after the previously scheduled Expiration Date.
During any such extension, all Original Notes previously tendered and not
withdrawn as herein provided will remain subject to the Exchange Offer and may
be accepted for exchange by URI.
 
INTEREST ON THE EXCHANGE NOTES
 
  Interest on the Notes is payable semi-annually on January 15 and July 15 of
each year, commencing July 15, 1999, at the rate of 9 1/4% per annum. The
Exchange Notes will bear interest from and including the last interest payment
date on the Original Notes (or, if none has yet occurred, the date of issuance
of such Original Notes). Accordingly, Holders of Original Notes that are
accepted for exchange will not receive interest that is accrued but unpaid on
the Original Notes at the time of tender, but such interest will be payable in
respect of the Exchange Notes delivered in exchange for such Original Notes on
the first interest payment date after the Expiration Date.
 
PROCEDURES FOR TENDERING
 
  Only a Book-Entry Holder of Original Notes may tender such Original Notes
pursuant to the Exchange Offer. To tender any Original Notes pursuant to the
Exchange Offer, the Book-Entry Holder of such Original Notes must make book-
entry delivery of such Original Notes by causing DTC to transfer such Original
Notes to the account of the Exchange Agent at DTC in accordance with DTC's
Automated Tender Offer Program
 
                                      23
<PAGE>
 
("ATOP") prior to 5:00 p.m., New York City time, on the Expiration Date. In
addition, either (i) DTC must deliver an Agent's Message (as defined below)
prior to 5:00 p.m., New York City time, on the Expiration Date, indicating
that DTC has received from such Book-Entry Holder an express acknowledgment
that such Book-Entry Holder has received and agrees to be bound by the terms
of the Letter of Transmittal or (ii) such Book-Entry Holder must complete,
sign and date the Letter of Transmittal or a facsimile thereof, in accordance
with the instructions contained herein and therein and deliver such Letter of
Transmittal, or such facsimile, and any other required documentation to the
Exchange Agent at the address set forth herein prior to 5:00 p.m., New York
City time, on the Expiration Date. DELIVERY OF DOCUMENTS TO DTC DOES NOT
CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.
 
  The term "Agent's Message" means a message transmitted by DTC to, and
received by, the Exchange Agent and forming part of the book-entry
confirmation relating to a book-entry transfer of Original Notes through ATOP,
which states that DTC has received an express acknowledgment from the DTC
Participant that is tendering the Original Notes which are the subject of such
book entry confirmation, that such DTC Participant has received and agrees to
be bound by the terms of the Letter of Transmittal.
 
  The tender by a holder of Original Notes and the acceptance thereof by URI
will constitute an agreement between such holder and URI in accordance with
the terms and subject to the conditions set forth herein and in the Letter of
Transmittal.
 
  THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF THE HOLDER.
INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN OVERNIGHT
OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO
ASSURE TIMELY DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE. NO
LETTER OF TRANSMITTAL SHOULD BE SENT TO THE COMPANY.
 
  All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Original Notes and withdrawal of tendered
Original Notes will be determined by URI in its sole discretion, which
determination will be final and binding. URI reserves the absolute right to
reject any and all Original Notes not properly tendered or any Original Notes
URI's acceptance of which would, in the opinion of counsel for URI, be
unlawful. URI also reserves the right to waive any irregularities or
conditions of tender as to particular Original Notes. URI's interpretation of
the terms and conditions of the Exchange Offer (including the instructions in
the Letter of Transmittal) will be final and binding on all parties. Unless
waived, any defects or irregularities in connection with tenders of Original
Notes must be cured within such time as URI shall determine. Neither URI, the
Exchange Agent nor any other person shall be under any duty to give
notification of defects or irregularities with respect to tenders of Original
Notes, nor shall any of them incur any liability for failure to give such
notification. Tenders of Original Notes will not be deemed to have been made
until such irregularities have been cured or waived. Any Original Notes
received by the Exchange Agent that are not properly tendered or the tender of
which is otherwise rejected by URI and as to which the defects or
irregularities have not been cured or waived will be returned by the Exchange
Agent to the Book-Entry Holder that tendered such Original Notes (by crediting
an account maintained at DTC designated by such Book-Entry Holder) as soon as
practicable following the Expiration Date.
 
WITHDRAWAL OF TENDERS
 
  Except as otherwise provided herein, tenders of Original Notes may be
withdrawn at any time prior to 5:00 p.m., New York City time, on the
Expiration Date.
 
  To withdraw a tender of Original Notes pursuant to the Exchange Offer, the
Book-Entry Holder that tendered such Original Notes must, prior to 5:00 p.m.,
New York City time, on the Expiration Date, either (i) withdraw such tender in
accordance with the appropriate procedures of the ATOP system or (ii) deliver
to the Exchange Agent a written or facsimile transmission notice of withdrawal
at the address set forth herein. Any
 
                                      24
<PAGE>
 
such notice of withdrawal must contain the name and number of the Book-Entry
Holder, the amount of Original Notes to which such withdrawal relates, the
account at DTC to be credited with the withdrawn Original Notes and the
signature of the Book-Entry Holder. All questions as to the validity, form and
eligibility (including time of receipt) of such withdrawal notices will be
determined by URI in its sole discretion, whose determination will be final
and binding on all parties. Any Original Notes so withdrawn will be deemed not
to have been validly tendered for purposes of the Exchange Offer, and no
Exchange Notes will be issued with respect thereto unless the Original Notes
so withdrawn are validly retendered. Any Original Notes which have been
tendered but which are withdrawn will be returned by the Exchange Agent to the
Book-Entry Holder that tendered such Original Notes (by crediting an account
maintained at DTC designated by such Book-Entry Holder) as soon as practicable
after withdrawal. Properly withdrawn Original Notes may be retendered at any
time prior to the Expiration Date by following the procedures described under
"--Procedures for Tendering."
 
CONDITIONS
 
  Notwithstanding any other term of the Exchange Offer, URI shall not be
required to accept for exchange, or to exchange Exchange Notes for, any
Original Notes, and may terminate or amend the Exchange Offer as provided
herein before the acceptance of such Original Notes, if:
 
  (a) any action or proceeding is instituted or threatened in any court or by
      or before any governmental agency or regulatory authority or any
      injunction, order or decree is issued with respect to the Exchange
      Offer which, in the sole judgment of URI, might impair the ability of
      URI to proceed with the Exchange Offer; or
 
  (b) any law, statute, rule, regulation or interpretation by the Staff of
      the Commission is proposed, adopted or enacted, which, in the
      reasonable judgment of URI, might materially impair the ability of URI
      to proceed with the Exchange Offer; or
 
  (c) there shall have been proposed, adopted or enacted any law, statute,
      rule or regulation (or an amendment to any existing law, statute, rule
      or regulation) which, in the sole judgment of URI, might materially
      impair the ability of URI to proceed with the Exchange Offer.
 
  If URI determines in its reasonable judgment that any of the conditions set
forth above are not satisfied, URI may (i) terminate the Exchange Offer and
refuse to accept any Original Notes and return all tendered Original Notes to
the tendering Holders, (ii) extend the Exchange Offer and retain all Original
Notes tendered prior to the expiration of the Exchange Offer subject, however,
to the rights of Holders to withdraw such Original Notes (see "--Withdrawals
of Tenders") or (iii) waive such unsatisfied conditions with respect to the
Exchange Offer and accept all properly tendered Original Notes which have not
been withdrawn. Moreover, regardless of whether any of such conditions has
occurred, URI may amend the Exchange Offer in any manner which, in its good
faith judgment, is advantageous to holders of the Original Notes.
 
  The foregoing conditions are for the sole benefit of URI and may be asserted
by URI regardless of the circumstances giving rise to any such condition or
may be waived by URI in whole or in part at any time and from time to time in
its sole discretion. The failure by URI at any time to exercise any of the
foregoing rights shall not be deemed a waiver of any such right, and each such
right shall be deemed an ongoing right which may be asserted at any time and
from time to time. If a waiver constitutes a material change in the Exchange
Offer, URI will disclose such change by means of a supplement to this
Prospectus that will be distributed to each Book-Entry Holder, and URI will
extend the Exchange Offer for a period of five to ten business days, depending
upon the significance of the waiver and the manner of disclosure to the Book-
Entry Holders, if the Exchange Offer would otherwise expire during such
period. Any determination by URI concerning the events described above will be
final and binding upon all parties.
 
  In addition, URI will not accept for exchange any Original Notes tendered,
and no Exchange Notes will be issued in exchange for any such Original Notes,
if at such time any stop order shall be threatened or in effect with respect
to the Registration Statement of which this Prospectus is a part or if the
Indenture is not qualified
 
                                      25
<PAGE>
 
under the Trust Indenture Act of 1939, as amended. URI is required to use
every reasonable effort to obtain the withdrawal of any such stop order at the
earliest possible time.
 
  The Exchange Offer is not conditioned upon any minimum principal amount of
Original Notes being tendered for exchange.
 
EXCHANGE AGENT
 
  State Street Bank and Trust Company, the Trustee under the Indenture, has
been appointed as Exchange Agent for the Exchange Offer. In such capacity, the
Exchange Agent has no fiduciary duties to the Holders of the Notes and will be
acting solely on the basis of directions of the Company. All executed Letters
of Transmittal must be directed to the Exchange Agent at the applicable
address set forth below. Questions and requests for assistance and requests
for additional copies of this Prospectus or the Letter of Transmittal should
be directed to the Exchange Agent addressed as follows:

  DELIVERY OF THE LETTER OF TRANSMITTAL TO AN ADDRESS OR FACSIMILE NUMBER
OTHER THAN SET FORTH ABOVE WILL NOT CONSTITUTE A VALID DELIVERY.
 
SOLICITATION OF TENDERS; FEES AND EXPENSES
 
  The expenses of soliciting tenders pursuant to the Exchange Offer will be
borne by URI. The principal solicitation for tenders pursuant to the Exchange
Offer is being made by mail; however, additional solicitations may be made by
telegraph, facsimile, telephone or in person by officers and regular employees
of URI and its affiliates.
 
  URI has not retained any dealer-manager in connection with the Exchange
Offer and will not make any payments to brokers, dealers or other persons
soliciting acceptances of the Exchange Offer. URI will, however, pay the
Exchange Agent reasonable and customary fees for its services and will
reimburse the Exchange Agent for its reasonable out-of-pocket expenses in
connection therewith and pay other expenses of the Exchange Offer, including
fees and expenses of the Trustee, filing fees, blue sky fees, accounting and
legal fees and printing and distribution expenses. URI may also pay brokerage
houses and other custodians, nominees and fiduciaries the reasonable out-of-
pocket expenses incurred by them in forwarding copies of this Prospectus,
Letters of Transmittal and related documents to the beneficial owners of the
Original Notes and in handling or forwarding tenders for exchange.
 
  URI will pay all transfer taxes, if any, applicable to the exchange of
Original Notes pursuant to the Exchange Offer. If, however, Exchange Notes or
Original Notes for principal amounts not tendered or accepted for exchange are
to be delivered to, or are to be registered or issued in the name of, any
person other than the Book-Entry Holder of the Original Notes tendered, or if
a transfer tax is imposed for any reason other than the exchange of Original
Notes pursuant to the Exchange Offer, then the amount of any such transfer
taxes (whether imposed on the Book-Entry Holder or any other persons) will be
payable by the tendering Holder. If satisfactory evidence of payment of such
taxes or exemption therefrom is not submitted with the Letter of Transmittal,
the amount of such transfer taxes will be billed directly to such tendering
Holder.
 
 
                                      26
<PAGE>
 
ACCOUNTING TREATMENT
 
  The Exchange Notes will be recorded at the same carrying value as the
Original Notes for which they are exchanged, which is the aggregate principal
amount of the Original Notes, as reflected in URI's accounting records on the
date of exchange. Accordingly, no gain or loss for accounting purposes will be
recognized in connection with the Exchange Offer. The cost of the Exchange
Offer will be deferred and amortized over the term of the Exchange Notes.
 
OTHER
 
  URI may in the future seek to acquire untendered Original Notes, to the
extent permitted by applicable law, in open market or privately negotiated
transactions, through subsequent exchange offers or otherwise. URI has no
present plans to acquire any Original Notes that are not tendered in the
Exchange Offer or to file a registration statement to permit resales of any
untendered Original Notes.
 
CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS
 
  The following is a general discussion of certain U.S. federal income tax
consequences of the Exchange Offer. This discussion is based on the current
provisions of the Internal Revenue Code of 1986, as amended (the "Code"),
applicable Treasury regulations, judicial authority and administrative rulings
and practice. This discussion is generally limited to the tax consequences to
Holders that hold the Exchange Notes as capital assets (within the meaning of
Section 1221 of the Code). There can be no assurance that the Internal Revenue
Service (the "Service") will not take a contrary view, and no ruling from the
Service has been or will be sought. Legislative, judicial or administrative
changes or interpretations may be forthcoming that could alter or modify the
statements and conditions set forth herein. Any such changes or
interpretations may or may not be retroactive and could affect the tax
consequences to Holders. Certain Holders, including insurance companies, tax-
exempt organizations, financial institutions, broker-dealers, foreign
corporations and persons who are not citizens or residents of the United
States, may be subject to special rules not discussed below.
 
  For U.S. federal income tax purposes, the exchange of Original Notes for
Exchange Notes pursuant to the Exchange Offer should not be treated as a
taxable transaction for federal income tax purposes. As a result, there should
be no federal income tax consequences to Holders exchanging Original Notes for
Exchange Notes pursuant to the Exchange Offer. A Holder should have the same
adjusted basis and holding period in an Exchange Note as it had in an Original
Note immediately prior to the exchange.
 
  THE FOREGOING DISCUSSION IS BASED ON THE PROVISIONS OF THE CODE,
REGULATIONS, TREASURY REGULATIONS, RULINGS AND JUDICIAL DECISIONS NOW IN
EFFECT, ALL OF WHICH ARE SUBJECT TO CHANGE. ANY SUCH CHANGES MAY BE APPLIED
RETROACTIVELY IN A MANNER THAT COULD ADVERSELY AFFECT HOLDERS EXCHANGING
NOTES. EACH HOLDER OF NOTES SHOULD CONSULT ITS OWN TAX ADVISOR WITH RESPECT TO
THE TAX CONSEQUENCES TO IT, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL,
FOREIGN AND OTHER TAX LAWS, OF EXCHANGING ORIGINAL NOTES FOR EXCHANGE NOTES
PURSUANT TO THE EXCHANGE OFFER.

                         REGISTRATION RIGHTS AGREEMENT
 
  In connection with the issuance of the Original Notes, the Company entered
into a Registration Rights Agreement with Goldman, Sachs & Co. (the
"Registration Rights Agreement"). Set forth below is a summary of certain
provisions of the Registration Rights Agreement. Such summary does not purport
to be complete and is subject to, and is qualified in its entirety by
reference to, all the provisions of the Registration Rights Agreement, a copy
of which is filed as an exhibit to the Registration Statement of which this
Prospectus forms a part.
 
EXCHANGE OFFER
 
  The Registration Rights Agreement provides that the Company is obligated to
(unless applicable law or Commission policy does not permit) (i) on or prior
to 90 days after the date (the "Issue Date") the Original Notes were
originally issued, file a registration statement (the "Exchange Registration
Statement") with the Commission with respect to an offer to exchange the
Original Notes for Exchange Notes, (ii) use its best efforts to cause the
Exchange Registration Statement to become effective under the Securities Act
on or prior to 150 days after the Issue Date, (iii) commence the exchange
offer contemplated by the Exchange Registration Statement promptly after the
registration statement is declared effective by the Commission and keep such
exchange offer open for acceptance for a period (the "Exchange Period") of 20
business days after the date notice of the exchange offer is mailed to the
holders of the Original Notes (or for such longer period as may be required by
law), (iv) use its best efforts to issue, promptly after the end of the
Exchange Period, Exchange Notes in exchange for all Original Notes that have
been properly tendered for exchange during the Exchange Period and (v) use its
best efforts to maintain the effectiveness of the Exchange Registration
Statement during the Exchange Period and thereafter until such time as the
Company has issued Exchange Notes in exchange for all Original Notes that have
been properly tendered for exchange during the Exchange Period. The exchange
offer contemplated by the Registration Rights Agreement will be deemed
consummated, for purposes of the Registration Rights Agreement, if the Company
makes such offer, such offer remains open for Exchange Period, and the Company
issues Exchange Notes in respect of all Original Notes that are properly
tendered during the Exchange Period.
 
  The Exchange Offer being made hereby is intended to satisfy the Company's
obligations under the Registration Rights Agreement described in the preceding
paragraph.
 
SHELF REGISTRATION STATEMENT
 
  If (i) the Company is not permitted to file the Exchange Registration
Statement or to consummate the exchange offer contemplated by the Registration
Rights Agreement because such offer is not permitted by applicable law or
Commission policy; (ii) for any other reason, the exchange offer contemplated
by the Registration Rights Agreement is not consummated within 180 days after
the Issue Date of the Original Notes; (iii) any holder of Original Notes or
Exchange Notes notifies the Company prior to the 20th day following
consummation of the Exchange Offer that (a) due to a change in law or policy
such holder is not entitled to participate in the Exchange Offer, (b) due to a
change in law or policy such holder may not resell the Exchange Notes acquired
by it in the Exchange Offer to the public without delivering a prospectus and
the prospectus contained in the Exchange Registration Statement is not
appropriate or available for such resales by such holder or (c) such holder is
a broker-dealer and owns Original Notes acquired directly from the Company or
an affiliate of the Company; or (iv) the holders of a majority in aggregate
principal amount of the Original Notes are not eligible to participate in the
Exchange Offer and to receive Exchange Notes that they may resell to the
public without restriction under the Securities Act and without restriction
under applicable blue sky or state securities laws, then the Company is
required to file with the Commission a shelf registration statement ("Shelf
Registration Statement") to cover resales of the Transfer Restricted Notes (as
defined below) by the holders thereof.
 
  If the Company is required to file the Shelf Registration Statement as
described in the preceding paragraph, the Company is obligated (i) to use its
best efforts to file the Shelf Registration Statement on or prior to the 90th
day after such filing obligation arises (except that, if the obligation to
file the Shelf Registration Statement arises
 
                                      28
<PAGE>
 
because the exchange offer contemplated by the Registration Rights Agreement
has not been consummated within 180 days after the Issue Date, then the
Company will use its best efforts to file the Shelf Registration Statement on
or prior to the 30th day after such filing obligation arises), (ii) following
the filing of the Shelf Registration Statement, to use its best efforts to
cause the Shelf Registration Statement to be declared effective by the
Commission on or prior to the 150th day after such filing obligation arises
and (iii) after the Shelf Registration Statement is declared effective by the
Commission, to use its best efforts to keep such Shelf Registration Statement
continuously effective, supplemented and amended (including through a post-
effective amendment on Form S-3 when the Company becomes eligible to file such
Form) until the second anniversary of the effective date of the Shelf
Registration Statement (or until one year after the effective date if the
Shelf Registration Statement is filed pursuant to clause (iv) above) or such
shorter period that will terminate when all the Transfer Restricted Notes
covered by the Shelf Registration Statement have been sold pursuant thereto.
 
  The term "Transfer Restricted Notes" means (i) each Original Note and (ii)
each Exchange Note that is issued to a broker-dealer in exchange for Original
Notes that were acquired by such broker-dealer for its own account as a result
of market-making activities or other trading activities; provided, however,
that a Note shall cease to be a Transfer Restricted Note when (a) such Note
has been effectively registered under the Securities Act and disposed of in
accordance with the Shelf Registration Statement or Broker Shelf Registration
Statement (as defined herein), or (b) such Note is eligible for distribution
to the public pursuant to Rule 144(k) under the Securities Act (or any similar
provision then in force, but not Rule 144A under the Securities Act), or (c)
such Note shall have been otherwise transferred by the holder thereof and a
new Note not bearing a legend restricting further transfer shall have been
delivered by the Company and subsequent disposition of such Note shall not
require registration or qualification under the Securities Act or any similar
state law then in force, or (d) such Note ceases to be outstanding or (e) in
the case of an Exchange Note that is a Transfer Restricted Note, such Exchange
Note is sold to a purchaser who receives from the seller on or prior to the
date of such sale a copy of the prospectus contained in the Exchange
Registration Statement, as amended or supplemented.
 
CERTAIN PROVISIONS RELATING TO BROKER-DEALERS
 
  A broker-dealer (a "Participating Broker-Dealer") that receives Exchange
Notes in exchange for Original Notes that were acquired by it for its own
account as a result of market-making activities or other trading activities,
will be required to deliver a prospectus meeting the requirements of the
Securities Act in connection with any resales by it of any such Exchange
Notes. This Prospectus, as it may be amended or supplemented from time to
time, may, if permitted by the Company, be used by a broker-dealer in order to
satisfy such prospectus delivery requirements. The Company has agreed in the
Registration Rights Agreement that it will use its best efforts to make this
Prospectus available to any such broker-dealer for use in connection with any
resales of such Exchange Notes (subject to the right of the Company to
restrict the use of this Prospectus under certain circumstances specified in
the Registration Rights Agreement). The obligation of the Company to make this
Prospectus available as aforesaid will commence on the day that the Exchange
Offer is consummated and continue in effect for a 30-day period (the "Broker
Prospectus Period"); provided, however, that, if for any day during such
period the Company restricts the use of such prospectus, the Broker Prospectus
Period shall be extended on a day-for-day basis.
 
  If at the end of the Broker Prospectus Period any Participating Broker-
Dealer continues to hold any Exchange Notes that it received in the Exchange
Offer, the Company is required (within the time period specified below), if
any such broker-dealer so requests within 60 days after the end of the Broker
Prospectus Period, to file with the Commission a shelf registration statement
(a "Broker Shelf Registration Statement") to cover the resale of such Exchange
Notes by such broker-dealers and use its best efforts to have such
registration statement declared effective by the Commission; provided,
however, that the Company may in lieu of filing such registration statement
extend the Broker Prospectus Period by 60 days.
 
  If the Company is required to file the Broker Shelf Registration Statement
as described in the preceding paragraph, the Company is obligated to (i) file
the Broker Shelf Registration Statement within 30 days following the date the
request for such registration statement is first made in accordance with the
Registration Rights
 
                                      29
<PAGE>
 
Agreement and (ii) use its best efforts to have the Broker Shelf Registration
Statement declared effective by the Commission on or prior to the 90th day
following the date the request for such registration statement is first made
in accordance with the Registration Rights Agreement. The Company will be
required to use its best efforts to keep the Broker Shelf Registration
Statement continuously effective, supplemented and amended for a 60-day
period; provided, however, that, if for any day during such period such
registration statement is not usable in connection with the resale of the
Exchange Notes covered thereby, such period shall be extended on a day-for-day
basis.
 
CERTAIN PROVISIONS RELATING TO ADDITIONAL INTEREST
 
  If a Registration Default (as defined herein) exists, the interest rate on
the Specified Notes (as defined below) will increase, with respect to the
first 90-day period (or portion thereof) while a Registration Default is
continuing immediately following the occurrence of such Registration Default,
 .25% per annum, such interest rate increasing by an additional .25% per annum
at the beginning of each subsequent 90-day period (or portion thereof) while a
Registration Default is continuing until all Registration Defaults have been
cured, up to a maximum rate of additional interest of 1.00% per annum.
Following the cure of all Registration Defaults the accrual of additional
interest on the Specified Notes will cease and the interest rate will revert
to the original rate. The Registration Rights Agreement provides that
additional interest as aforesaid will constitute liquidated damages and will
be the exclusive monetary remedy available to holders of the Original Notes or
Exchange Notes in respect of any Registration Default. The "Specified Notes"
mean the Original Notes (and not the Exchange Notes); provided, however, that
the Specified Notes means the Exchange Notes (and not the Original Notes) with
respect to (a) any Registration Default that arises pursuant to clause (i) or
(ii) of the definition of such term and relates solely to the Broker Shelf
Registration Statement and (b) any Registration Default that arises solely
pursuant to clause (v) or (vi) of the definition of such term.
 
  A "Registration Default" will exist (subject to the following sentence) if
(i) the Company fails to file any of the registration statements required by
the Registration Rights Agreement on or prior to the date specified for such
filing, (ii) any of such registration statements is not declared effective by
the Commission on or prior to the date specified for such effectiveness, (iii)

     SELECTED HISTORICAL AND PRO FORMA CONSOLIDATED FINANCIAL INFORMATION
 
  The tables below present selected historical and pro forma financial
information for the Company. This information should be read together with (1)
the Consolidated Financial Statements and the related notes thereto and Pro
Forma Consolidated Financial Statements and the related notes thereto of the
Company included elsewhere in this prospectus or incorporated by reference
herein and (2) the financial statements incorporated by reference in this
prospectus of certain of the companies that we acquired.
 
  The balance sheet data presented below as of December 31, 1996 and 1997 and
the income statement data presented below for each of the years in the three-
year period ended December 31, 1997 are derived from the audited Consolidated
Financial Statements of the Company. Such financial statements are
incorporated by reference in this prospectus. The balance sheet data presented
below as of December 31, 1993, 1994 and 1995 and as of September 30, 1998 and
the income statement data presented below for the years ended December 31,
1993 and 1994 and for the nine-month periods ended September 30, 1997 and 1998
are derived from the unaudited consolidated financial statements of the
Company which include, in the opinion of management of the Company, all
adjustments (consisting of normal recurring accruals) necessary to present
fairly the results of operations and financial position of the Company for the
periods and the dates presented.
 
  The Company commenced operations in October 1997 by acquiring six
established equipment rental companies. The Company completed 91 additional
acquisitions (through February 11, 1999), including the merger with U.S.
Rentals which was completed in September 1998. Three of these acquisitions
(including the U.S. Rentals merger) were accounted for as "poolings-of-
interests," which means that for accounting and financial reporting purposes
the acquired company is treated as having been combined with the Company at
all times since the inception of the acquired company. Accordingly, the
Company's financial statements have been restated to include the accounts of
two of the companies acquired in these pooling-of-interests transactions (but
were not restated for one that was not material, which has been combined with
the Company effective July 1, 1998). As a result of this restatement, the
Company's financial statements include historical financial information for
periods that precede the date on which the Company commenced its own
operations. See Note 3 to the Consolidated Financial Statements of the Company
incorporated by reference herein. The other 94 acquisitions completed by the
Company were accounted for as "purchases," which means that the results of
operations of the acquired company are included in the Company's financial
statements only from the date of acquisition.
 
  The following unaudited income statement and other financial data under the
column heading "Pro Forma" with respect to each period presented gives effect
to each acquisition completed by the Company after the beginning of the period
(through February 11, 1999) and the financing thereof, as if all such
transactions had occurred at the beginning of the period. The following
unaudited balance sheet data as of September 30, 1998 under the column heading
"Pro Forma" gives effect to each acquisition completed by the Company
subsequent to such date (through February 11, 1999) and the financing of each
such acquisition, as if all such transactions had occurred on such date.
 
  The pro forma data set forth below is provided for informational purposes.
However, this data may not be indicative of the actual results that the
Company would have had during any period presented, had any or all of the
acquisitions been completed as of the beginning of that period, or of any
future results.

(1) The Company recorded an extraordinary item (net of income taxes) of $1.5
    million in 1997 and an extraordinary item (net of income taxes) of $21.3
    million in 1998. Such charge in 1997 resulted from the prepayment of
    certain debt by U.S. Rentals. Such charge in 1998 resulted from the early
    extinguishment of certain debt and primarily reflected prepayment
    penalties on certain debt of U.S. Rentals.
(2) U.S. Rentals was taxed as a Subchapter S Corporation until its initial
    public offering in February 1997, and another acquired company was taxed
    as a Subchapter S Corporation until being acquired by the Company in 1998.
    In general, the income or loss of a Subchapter S Corporation is passed
    through to its owners rather than being subjected to taxes at the entity
    level. Pro forma provision for income taxes before extraordinary items and
    pro forma income (loss) before extraordinary items reflect a provision for
    income taxes as if all such companies were liable for federal and state
    income taxes as taxable corporate entities for all periods presented.
(3) EBITDA is defined as net income (excluding (i) non-operating income and
    expense, (ii) a $20.3 million non-recurring charge incurred by U.S.
    Rentals in 1997 arising from the termination of deferred compensation
    agreements with certain executives and (iii) $42.2 million in merger-
    related expenses in 1998 related to the three acquisitions accounted for
    as poolings-of-interests, including the merger with U.S. Rentals) plus
    interest expense, income taxes and depreciation and amortization. EBITDA
    data is presented to provide additional information concerning the
    Company's ability to meet its future debt service obligations and capital
    expenditure and working capital requirements. However, EBITDA is not a
    measure of financial performance under generally accepted accounting
    principles. Accordingly, EBITDA should not be considered an alternative to
    net income or cash flows as indicators of the Company's operating
    performance or liquidity.
(4) EBITDA margin is defined as EBITDA as a percentage of revenues.
(5) Interest expense excludes the amortization of deferred financing fees.
(6) URI is a wholly owned subsidiary of Holdings. Although not legally
    obligated to do so, URI has made, and expects that it will continue to
    make, cash distributions to Holdings in order to enable Holdings to pay
    dividends on certain preferred securities that were issued by a subsidiary
    trust of Holdings. These distributions are not reflected in URI's interest
    expense.
(7) For purposes of determining the ratio of total debt to EBITDA for the nine
    months ended September 30, 1998, EBITDA is annualized.
(8) For purposes of determining the ratio of earnings to fixed charges, (i)
    earnings consist of income before income taxes and extraordinary items
    plus fixed charges and (ii) fixed charges consist of interest expense,
    amortization of debt issuance costs, and the estimated interest portion of
    rental expense.
(9) The pro forma ratio of earnings to fixed charges gives effect to the
    issuance of the Notes and the application of a portion of the net proceeds
    therefrom to repay outstanding indebtedness, as if such transaction had
    occurred at the beginning of the period.
(10) The supplemental pro forma ratio of earnings to fixed charges gives
     effect to each acquisition completed by the Company after the beginning
     of the period and the financing thereof, as if such transactions had
     occurred at the beginning of the period.

                           DESCRIPTION OF THE NOTES
 
  The Exchange Notes offered hereby will be issued, and the Original Notes
were issued, under an Indenture dated as of December 15, 1998 (the
"Indenture"), among the Company, the Guarantors and State Street Bank & Trust
Company, as trustee (the "Trustee"). References to the Notes include both the
Original Notes and the Exchange Notes. Upon the effectiveness of the
Registration Statement of which this Prospectus is a part, the Indenture will
be subject to and governed by the Trust Indenture Act of 1939, as amended (the
"Trust Indenture Act").
 
  The following summary of the material provisions of the Indenture and the
Notes does not purport to be complete and is subject to, and qualified in its
entirety by, reference to the provisions of the Indenture and the Notes,
including the definitions of certain terms contained therein and those terms
made part of the Indenture by reference to the Trust Indenture Act. The
definition of certain capitalized terms used in the following summary are set
forth below under "--Certain Definitions." All references to the Company in
the following summary refer exclusively to URI, and not to any of its
subsidiaries.
 
ORIGINAL NOTES AND EXCHANGE NOTES WILL REPRESENT SAME DEBT
 
  The Exchange Notes will be issued solely in exchange for an equal principal
amount of Original Notes pursuant to the Exchange Offer. The Exchange Notes
will evidence the same debt as the Original Notes and both series of Notes
will be entitled to the benefits of the Indenture and treated as a single
class of debt securities. The terms of the Exchange Notes will be the same in
all material respects as the Original Notes except that (i) the Exchange Notes
will be registered under the Securities Act, and therefore, will not bear
legends restricting the transfer thereof and (ii) certain of the registration
rights, under the Registration Rights Agreement, relating to the Exchange
Notes are different than those relating to the Original Notes and, therefore,
the defaults under the Registration Rights Agreement that may require the
Company to pay additional interest will be different for the Exchange Notes
and the Original Notes. See "Registration Rights Agreement--Certain Provisions
Relating to Additional Interest" and "--Additional Interest."
 
  If the Exchange Offer is consummated, holders of Original Notes who do not
exchange their Original Notes for Exchange Notes will vote together with
holders of the Exchange Notes for all relevant purposes under the Indenture.
Accordingly, all references herein to specified percentages in aggregate
principal amount of the outstanding Notes shall be deemed to mean, at any time
after the Exchange Offer is consummated, such percentages in aggregate
principal amount of the Original Notes and the Exchange Notes then
outstanding.
 
GENERAL
 
  The Notes are unsecured senior subordinated obligations of the Company
limited to $300 million aggregate principal amount, and are guaranteed by each
of the Guarantors on a senior subordinated basis as described below. The Notes
may be issued only in registered form without coupons, in denominations of
$1,000 and integral multiples thereof. Principal of, premium, if any, and
interest on the Notes is payable, and the Notes will be transferable, at the
corporate trust office or agency of the Trustee in the City of New York
maintained for such purposes. In addition, interest may be paid at the option
of the Company by check mailed to the person entitled thereto as shown on the
security register. No service charge will be made for any transfer, exchange
or redemption of Notes, except in certain circumstances for any tax or other
governmental charge that may be imposed in connection therewith.
 
MATURITY, INTEREST AND PRINCIPAL
 
  The Notes will mature on January 15, 2009. Interest on the Notes will accrue
at the rate of 9.25% per annum and will be payable semi-annually in arrears on
each January 15 and July 15, commencing July 15, 1999, to the holders of
record of Notes at the close of business on the January 1 and July 1,
respectively, immediately preceding such interest payment date. Interest on
the Notes will accrue from the most recent date to which interest has been
paid or, if no interest has been paid, from the original date of issuance of
the Original Notes (the "Issue Date"). Interest will be computed on the basis
of a 360-day year comprised of twelve 30-day months.

ADDITIONAL INTEREST
 
  The interest rate on the Notes is subject to increase under certain
circumstances if the Company is not in compliance with its obligations under
the Registration Rights Agreement. See "Exchange Offer; Registration Rights."
 
OPTIONAL REDEMPTION
 
  Optional Redemption. The Notes will be redeemable at the option of the
Company, in whole or in part, at any time on or after January 15, 2004, at the
redemption prices (expressed as percentages of principal amount) set forth
below, plus accrued and unpaid interest, if any, to the redemption date, if
redeemed during the 12-month period beginning January 15 of the years
indicated below:

</TABLE>
 
  In addition, at any time, or from time to time, on or prior to January 15,
2002, the Company may, at its option, use the net cash proceeds of one or more
Public Equity Offerings (as defined below) to redeem up to an aggregate of 35%
of the principal amount of the Notes originally issued, at a redemption price
equal to 109.25% of the principal amount thereof plus accrued and unpaid
interest, if any, thereon to the redemption date; provided that at least 65%
of the originally issued principal amount of Notes remains outstanding
immediately after the occurrence of such redemption. In order to effect the
foregoing redemption with the proceeds of any Public Equity Offering the
Company shall send a redemption notice to the Trustee not later than 90 days
after the consummation of any such Public Equity Offering.
 
  As used in the preceding paragraph, "Public Equity Offering" means an
underwritten public offering of Common Stock pursuant to a registration
statement filed with the Commission in accordance with the Securities Act.
 
  Selection and Notice. In the event that less than all of the Notes are to be
redeemed at any time, selection of such Notes for redemption will be made by
the Trustee in compliance with the requirements of the principal national
securities exchange, if any, on which the Notes are listed or, if the Notes
are not then listed on a national securities exchange, on a pro rata basis, by
lot or by such method as the Trustee shall deem fair and appropriate (subject
to the rules of DTC); provided, however, that Notes shall only be redeemable
in principal amounts of $1,000 or an integral multiple of $1,000. Notice of
redemption shall be mailed by first-class mail at least 30 but not more than
60 days before the redemption date to each holder of Notes to be redeemed at
its registered address. If any Note is to be redeemed in part only, the notice
of redemption that relates to such Note shall state the portion of the
principal amount thereof to be redeemed. A new Note in a principal amount
equal to the unredeemed portion thereof will be issued in the name of the
holder thereof upon surrender for cancellation of the original Note. On and
after the redemption date, interest will cease to accrue on Notes or portions
thereof called for redemption, unless the Company defaults in the payment of
the redemption price.
 
SINKING FUND
 
  The Notes will not be entitled to the benefit of any mandatory sinking fund.
 
CHANGE OF CONTROL
 
  Upon the occurrence of a Change of Control, the Company shall be obligated
to make an offer to purchase (a "Change of Control Offer"), on a business day
(the "Change of Control Purchase Date") not more than 60
 
                                      35
<PAGE>
 
nor less than 30 days following the occurrence of the Change of Control, all
of the then outstanding Notes tendered at a purchase price in cash (the
"Change of Control Purchase Price") equal to 101% of the principal
amount thereof plus accrued and unpaid interest, if any, thereon to the Change
of Control Purchase Date. The Company shall be required to purchase all Notes
tendered into the Change of Control Offer and not withdrawn. The Change of
Control Offer is required to remain open for at least 20 business days.
 
  In order to effect such Change of Control Offer, the Company shall, not
later than the 30th day after the Change of Control, mail to each holder of
Notes notice of the Change of Control Offer, which notice shall govern the
terms of the Change of Control Offer and shall state, among other things, the
procedures that holders of Notes must follow to accept the Change of Control
Offer.
 
  If a Change of Control Offer is made, there can be no assurance that the
Company will have available funds sufficient to pay the Change of Control
Purchase Price for all of the Notes that might be delivered by holders of
Notes seeking to accept the Change of Control Offer. In addition, there can be
no assurance that the Company's debt instruments will permit such offer to be
made. The agreements governing the Company's Senior Indebtedness do not permit
the Company to make a Change of Control Offer and, in order to make such
offer, the Company would be required to pay off such Senior Indebtedness in
full or seek a waiver from the lenders of such Senior Indebtedness to allow
the Company to make the Change of Control Offer. The occurrence of a Change of
Control is also an event of default under the agreements governing the Credit
Facility and the Term Loan and would entitle the lenders to accelerate all
amounts owing thereunder. Failure to make a Change of Control Offer, even if
prohibited by the Company's debt instruments, would constitute a default under
the Indenture. Pursuant to the indentures governing the 9 1/2% Notes and the
8.80% Notes the Company is also required to make an offer to repurchase the 9
1/2% Notes and the 8.80% Notes upon a Change of Control, and failure by the
Company to make such an offer is an event of default under those indentures.
See "Risk Factors--Possible Inability to Repurchase Notes upon Change of
Control." The Company shall not be required to make a Change of Control Offer
upon a Change of Control if a third party makes the Change of Control Offer in
the manner, at the times and otherwise in compliance with the requirements
applicable to a Change of Control Offer made by the Company and purchases all
Notes validly tendered and not withdrawn under such Change of Control Offer.
 
  The definition of "Change of Control" excludes certain transactions by
Permitted Holders, including a direct or indirect sale, lease, exchange or
other transfer of all or substantially all of the assets of the Company to
Permitted Holders. The provisions of the Indenture may not afford Noteholders
protection in the event of a highly leveraged transaction, reorganization,
restructuring, merger or similar transaction involving the Company if such
transaction is not a transaction defined as a "Change of Control."
 
  The use of the term "all or substantially all" in provisions of the
Indenture such as clause (b) of the definition of "Change of Control" and
under "--Consolidation, Merger, Sale of Assets, Etc." has no clearly
established meaning under New York law (which governs the Indenture) and has
been the subject of limited judicial interpretation in only a few
jurisdictions. Accordingly, there may be a degree of uncertainty in
ascertaining whether any particular transaction would involve a disposition of
"all or substantially all" of the assets of a person, which uncertainty should
be considered by prospective purchasers of Notes.
 
  The Company will comply with Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder, to the extent such laws or
regulations are applicable, in the event that a Change of Control occurs and
the Company is required to purchase Notes as described above.
 
SUBORDINATION
 
  The indebtedness evidenced by the Notes is subordinated in right of payment
to the prior payment in full in cash of all Senior Indebtedness. The Notes are
senior subordinated indebtedness of the Company ranking senior to all existing
and future Subordinated Indebtedness of the Company.
 
 
                                      36
<PAGE>
 
  The Indenture provides that in the event of any insolvency or bankruptcy
case or proceeding, or any receivership, liquidation, reorganization or other
similar case or proceeding in connection therewith, relating to the Company or
its assets, or any liquidation, dissolution or other winding-up of the
Company, whether voluntary or involuntary, or any assignment for the benefit
of creditors or other marshalling of assets or liabilities of the Company, all
Senior Indebtedness (including, in the case of Designated Senior Indebtedness,
any interest accruing subsequent to the filing of a petition for bankruptcy
regardless of whether such interest is an allowed
claim in the bankruptcy proceeding) must be paid in full in cash before any
payment is made on account of the principal of, premium, if any, or interest
on the Notes.
 
  During the continuance of any default in the payment of principal, premium,
if any, or interest on any Senior Indebtedness, when the same becomes due, and
after receipt by the Trustee and the Company from representatives of holders
of such Senior Indebtedness of written notice of such default, no direct or
indirect payment (other than payments from trusts previously created pursuant
to the provisions described under "--Defeasance or Covenant Defeasance of
Indenture") by or on behalf of the Company of any kind of character (excluding
certain permitted equity or subordinated securities) may be made on account of
the principal of, premium, if any, or interest on, or the purchase, redemption
or other acquisition of, the Notes unless and until such default has been
cured or waived or has ceased to exist or such Senior Indebtedness shall have
been discharged or paid in full in cash, after which the Company shall resume
making any and all required payments in respect of the Notes, including any
missed payments.
 
  In addition, during the continuance of any other default with respect to any
Designated Senior Indebtedness that permits, or would permit with the passage
of time or the giving of notice or both, the maturity thereof to be
accelerated (a "Non-payment Default") and upon the earlier to occur of (a)
receipt by the Trustee and the Company from the representatives of holders of
such Designated Senior Indebtedness of a written notice of such Non-payment
Default or (b) if such Non-payment Default results from the acceleration of
the maturity of the Notes, the date of such acceleration, no payment (other
than payments from trusts previously created pursuant to the provisions
described under "--Defeasance or Covenant Defeasance of Indenture") of any
kind or character (excluding certain permitted equity or subordinated
securities) may be made by the Company on account of the principal of,
premium, if any, or interest on, or the purchase, redemption, or other
acquisition of, the Notes for the period specified below (the "Payment
Blockage Period").
 
  The Payment Blockage Period shall commence upon the receipt of notice of a
Non-payment Default by the Trustee and the Company from the representatives of
holders of Designated Senior Indebtedness or the date of the acceleration
referred to in clause (b) of the preceding paragraph, as the case may be, and
shall end on the earliest to occur of the following events: (i) 179 days have
elapsed since the receipt of such notice or the date of the acceleration
referred to in clause (b) of the preceding paragraph (provided the maturity of
such Designated Senior Indebtedness shall not theretofore have been
accelerated), (ii) such default is cured or waived or ceases to exist or such
Designated Senior Indebtedness is discharged or paid in full in cash, or (iii)
such Payment Blockage Period shall have been terminated by written notice to
the Company or the Trustee from the representatives of holders of Designated
Senior Indebtedness initiating such Payment Blockage Period, after which the
Company shall promptly resume making any and all required payments in respect
of the Notes, including any missed payments. Only one Payment Blockage Period
with respect to the Notes may be commenced within any 360 consecutive day
period. No Non-payment Default with respect to Designated Senior Indebtedness
that existed or was continuing on the date of the commencement of any Payment
Blockage Period will be, or can be, made the basis for the commencement of a
second Payment Blockage Period, whether or not within a period of 360
consecutive days, unless such default has been cured or waived for a period of
not less than 90 consecutive days. In no event will a Payment Blockage Period
extend beyond 179 days from the date of the receipt by the Trustee of the
notice or the date of the acceleration initiating such Payment Blockage Period
and there must be a 180 consecutive day period in any 360 day period during
which no Payment Blockage Period is in effect.
 
  If the Company fails to make any payment on the Notes when due on account of
the payment blockage provisions referred to above, such failure would
constitute an Event of Default under the Indenture and would enable the
holders of the Notes to accelerate the maturity thereof. See "--Events of
Default."
 
                                      37
<PAGE>
 
  By reason of such subordination, in the event of liquidation or insolvency,
creditors of the Company who are holders of Senior Indebtedness may recover
more, ratably, than the holders of the Notes, and funds which would be
otherwise payable to the holders of the Notes will be paid to the holders of
Senior Indebtedness to the extent necessary to pay the Senior Indebtedness in
full, and the Company may be unable to meet its obligations fully with respect
to the Notes.
 
  The Indenture limits, but does not prohibit, the incurrence by the Company
of additional Indebtedness which is senior to the Notes and prohibits the
incurrence by the Company of Indebtedness which is subordinated in right of
payment to any other Indebtedness of the Company and senior in right of
payment to the Notes.
 
  "Designated Senior Indebtedness" means (i) all Indebtedness under the Credit
Facility and the Term Loan and (ii) any other issue of Senior Indebtedness
which (a) at the time of the determination is equal to or greater than $25
million in aggregate principal amount and (b) is specifically designated by
the Company in the instrument evidencing such Senior Indebtedness as
"Designated Senior Indebtedness."
 
  "Senior Indebtedness" means the principal of, premium, if any, and interest
on any Indebtedness of the Company, whether outstanding on the Issue Date or
thereafter created, incurred or assumed, unless, in the case of any particular
Indebtedness, the instrument creating or evidencing the same or pursuant to
which the same is outstanding expressly provides that such Indebtedness shall
not be senior in right of payment to the Notes. Without limiting the
generality of the foregoing, (x) "Senior Indebtedness" shall include the
principal of, premium, if any, and interest on all obligations of every nature
of the Company from time to time owed to the lenders under the Credit Facility
and the Term Loan, including, without limitation, principal of and interest
on, and all fees, indemnities and expenses payable under the Credit Facility
and the Term Loan, and (y) in the case of Designated Senior Indebtedness,
"Senior Indebtedness" shall include interest accruing thereon subsequent to
the occurrence of any Event of Default specified in clause (vii) or (viii)
under "--Events of Default" relating to the Company, whether or not the claim
for such interest is allowed under any applicable Bankruptcy Code.
Notwithstanding the foregoing, "Senior Indebtedness" shall not include (a)
Indebtedness evidenced by the Notes, (b) Indebtedness that is expressly
subordinate or junior in right of payment to any Indebtedness of the Company,
including the Company's 9 1/2% Notes and 8.80% Notes, (c) Indebtedness which,
when incurred and without respect to any election under Section 1111(b) of
Title 11, United States Code, is without recourse to the Company, (d)
Indebtedness which is represented by Redeemable Capital Stock,
(e) Indebtedness for goods, materials or services purchased in the ordinary
course of business or Indebtedness consisting of trade payables or other
current liabilities (other than any current liabilities owing under the Credit
Facility, or the current portion of any long-term Indebtedness which would
constitute Senior Indebtedness but for the operation of this clause (e)), (f)
Indebtedness of or amounts owed by the Company for compensation to employees
or for services rendered to the Company, (g) any liability for federal, state,
local or other taxes owed or owing by the Company, (h) Indebtedness of the
Company to a Subsidiary of the Company or any other Affiliate of the Company
or any of such Affiliate's Subsidiaries, (i) that portion of any Indebtedness
which is incurred by the Company in violation of the Indenture and (j) amounts
owing under leases.
 
GUARANTEES
 
  Each Guarantor has fully and unconditionally guaranteed, on a senior
subordinated basis, jointly and severally, to each holder and the Trustee, the
full and prompt performance of the Company's obligations under the Indenture
and the Notes, including the payment of principal of and interest on the
Notes. The Guarantees are subordinated to Guarantor Senior Indebtedness on the
same basis as the Notes are subordinated to Senior Indebtedness.
 
  The obligations of each Guarantor are limited to the maximum amount which,
after giving effect to all other contingent and fixed liabilities of such
Guarantor and after giving effect to any collections from or payments made by
or on behalf of any other Guarantor in respect of the obligations of such
other Guarantor under its Guarantee or pursuant to its contribution
obligations under the Indenture, will result in the obligations of such
Guarantor under the Guarantee not constituting a fraudulent conveyance or
fraudulent transfer under federal or state law. See "Risk Factors--Fraudulent
Transfer Considerations."
 
                                      38
<PAGE>
 
  Each Guarantor that makes a payment or distribution under a Guarantee shall
be entitled to a contribution from each other Guarantor in an amount pro rata,
based on the net assets of each Guarantor, determined in accordance with GAAP.
 
  Each Guarantor may consolidate with or merge into or sell its assets to the
Company or another Guarantor without limitation, or with other persons upon
the terms and conditions set forth in the Indenture. See "--Consolidation,
Merger, Sale of Assets, Etc." In the event all or substantially all of the
assets or the capital stock of a Guarantor is sold and the sale complies with
the provisions set forth in "--Certain Covenants--Limitation on Asset Sales,"
the Guarantor's Guarantee will be automatically discharged and released.
 
  "Guarantor Senior Indebtedness" of a Guarantor means the principal of,
premium, if any, and interest on any Indebtedness of such Guarantor, whether
outstanding on the Issue Date or thereafter created, incurred or assumed,
unless, in the case of any particular Indebtedness, the instrument creating or
evidencing the same or pursuant to which the same is outstanding expressly
provides that such Indebtedness shall not be senior in right of payment to the
Notes or such Guarantor's Guarantee. Without limiting the generality of the
foregoing, (x) "Guarantor Senior Indebtedness" shall include the principal of,
premium, if any, and interest on all obligations of every nature of such
Guarantor from time to time owed to the lenders under the Credit Facility and
Term Loan, including, without limitation, principal of and interest on, and
all fees, indemnities and expenses payable under the Credit Facility and Term
Loan, and (y) in the case of amounts owing under the Credit Facility and Term
Loan and guarantees of Designated Senior Indebtedness, "Guarantor Senior
Indebtedness" shall include interest accruing thereon subsequent to the
occurrence of any Event of Default specified in clause (vii) or (viii) under
"--Events of Default" relating to such Guarantor, whether or not the claim for
such interest is allowed under any applicable Bankruptcy Code. Notwithstanding
the foregoing, "Guarantor Senior Indebtedness" shall not include (a)
Indebtedness evidenced by the Notes or the Guarantees, (b) Indebtedness that
is expressly subordinate or junior in right of payment to any Indebtedness of
such Guarantor, including the Guarantor's guarantee of the Company's 9 1/2%
Notes and 8.80% Notes, (c) Indebtedness which, when incurred and without
respect to any election under Section 1111(b) of Title 11, United States Code,
is without recourse to such Guarantor, (d) Indebtedness which is represented
by Redeemable Capital Stock, (e) Indebtedness for goods, materials or services
purchased in the ordinary course of business or Indebtedness consisting of
trade payables or other current liabilities (other than any current
liabilities owing under the Credit Facility, or the current portion of any
long-term Indebtedness which would constitute Guarantor Senior Indebtedness
but for the operation of this clause (e)), (f) Indebtedness of or amounts owed
by such Guarantor for compensation to employees or for services rendered to
such Guarantor, (g) any liability for federal, state, local or other taxes
owed or owing by such Guarantor, (h) Indebtedness of such Guarantor to the
Company or a Subsidiary of the Company or any other Affiliate of the Company
or any of such Affiliate's Subsidiaries, (i) that portion of any Indebtedness
which is incurred by such Guarantor in violation of the Indenture and (j)
amounts owing under leases.
 
CERTAIN COVENANTS
 
  The Indenture contains the following covenants, among others:
 
  Limitation on Indebtedness. The Company will not, and will not permit any of
its Restricted Subsidiaries to, directly or indirectly, create, incur, issue,
assume, guarantee or in any manner become directly or indirectly liable,
contingently or otherwise (in each case, to "incur"), for the payment of any
Indebtedness (including any Acquired Indebtedness) other than Permitted
Indebtedness; provided, however, that (i) the Company and any Guarantor will
be permitted to incur Indebtedness (including Acquired Indebtedness), and (ii)
a Restricted Subsidiary will be permitted to incur Acquired Indebtedness, if
in each case, after giving pro forma effect to (1) the incurrence of such
Indebtedness and (if applicable) the application of the net proceeds
therefrom, including to refinance other Indebtedness, as if such Indebtedness
were incurred at the beginning of the four full fiscal quarters immediately
preceding such incurrence, taken as one period; (2) the incurrence, repayment
or retirement of any other Indebtedness by the Company and its Restricted
Subsidiaries since the first day of such four-quarter period as if such
Indebtedness was incurred, repaid or retired at the beginning of such four-
quarter period (except that, in making such computation, the amount of
Indebtedness under any revolving credit facility shall be
 
                                      39
<PAGE>
 
computed based upon the average daily balance of such Indebtedness during such
four-quarter period); and (3) any Asset Sale or Asset Acquisition occurring
since the first day of such four-quarter period (including to the date of
calculation) as if such acquisition or disposition occurred at the beginning
of such four-quarter period, the Consolidated Fixed Charge Coverage Ratio of
the Company is at least 2:1.
 
  Limitation on Restricted Payments. The Company will not, and will not permit
any of its Restricted Subsidiaries to, directly or indirectly:
 
    (a) declare or pay any dividend or make any other distribution or payment
  on or in respect of Capital Stock of the Company or any of its Restricted
  Subsidiaries or make any payment to the direct or indirect holders (in
  their capacities as such) of Capital Stock of the Company or any of its
  Restricted Subsidiaries (other than dividends or distributions payable
  solely in Capital Stock of the Company (other than Redeemable Capital
  Stock) or in options, warrants or other rights to purchase Capital Stock of
  the Company (other than Redeemable Capital Stock)) (other than the
  declaration or payment of dividends or other distributions to the extent
  declared or paid to the Company or any Restricted Subsidiary),
 
    (b) purchase, redeem, defease or otherwise acquire or retire for value
  any Capital Stock of the Company or any of its Restricted Subsidiaries or
  any options, warrants, or other rights to purchase any such Capital Stock
  (other than any such securities owned by the Company or a Restricted
  Subsidiary),
 
    (c) make any principal payment on, or purchase, defease, repurchase,
  redeem or otherwise acquire or retire for value, prior to any scheduled
  maturity, scheduled repayment, scheduled sinking fund payment or other
  Stated Maturity, any Subordinated Indebtedness (other than any such
  Subordinated Indebtedness owned by the Company or a Restricted Subsidiary),
  or
 
    (d) make any Investment (other than any Permitted Investment) in any
  person
 
  (such payments or Investments described in the preceding clauses (a), (b),
  (c) and (d) are collectively referred to as "Restricted Payments"), unless,
  after giving effect to the proposed Restricted Payment (the amount of any
  such Restricted Payment, if other than cash, shall be the Fair Market Value
  of the asset(s) proposed to be transferred by the Company or such
  Restricted Subsidiary, as the case may be, pursuant to such Restricted
  Payment), (A) no Default or Event of Default shall have occurred and be
  continuing, (B) immediately after giving effect to such Restricted Payment,
  the Company would be able to incur $1.00 of additional Indebtedness (other
  than Permitted Indebtedness) (assuming a market rate of interest with
  respect to such additional Indebtedness) and (C) the aggregate amount of
  all Restricted Payments declared or made from and after the Issue Date
  would not exceed the sum of:
 
    (1) 50% of the aggregate Consolidated Net Income of the Company accrued
  on a cumulative basis during the period beginning on May 22, 1998 and
  ending on the last day of the fiscal quarter of the Company immediately
  preceding the date of such proposed Restricted Payment (or, if such
  aggregate cumulative Consolidated Net Income of the Company for such period
  shall be a deficit, minus 100% of such deficit);
 
    (2) the aggregate net cash proceeds received by the Company as capital
  contributions to the Company after May 22, 1998 and which constitute
  shareholders' equity of the Company in accordance with GAAP;
 
    (3) the aggregate net cash proceeds received by the Company from the
  issuance or sale of Capital Stock (excluding Redeemable Capital Stock) of
  the Company to any person (other than to a Subsidiary of the Company) after
  May 22, 1998;
 
    (4) the aggregate net cash proceeds received by the Company from any
  person (other than a Subsidiary of the Company) upon the exercise of any
  options, warrants or rights to purchase shares of Capital Stock (other than
  Redeemable Capital Stock) of the Company after May 22, 1998;
 
    (5) the aggregate net cash proceeds received after May 22, 1998 by the
  Company from any person (other than a Subsidiary of the Company) for debt
  securities that have been converted or exchanged into or for Capital Stock
  of the Company (other than Redeemable Capital Stock) (to the extent such
  debt securities
 
                                      40
<PAGE>
 
  were originally sold for cash) plus the aggregate amount of cash received
  by the Company (other than from a Subsidiary of the Company) in connection
  with such conversion or exchange;
 
    (6) in the case of the disposition or repayment of any Investment
  constituting a Restricted Payment after May 22, 1998, an amount equal to
  the lesser of the return of capital with respect to such Investment and the
  initial amount of such Investment, in either case, less the cost of the
  disposition of such Investment; and
 
    (7) so long as the Designation thereof was treated as a Restricted
  Payment made after May 22, 1998, with respect to any Unrestricted
  Subsidiary that has been redesignated as a Restricted Subsidiary after the
  Issue Date in accordance with "--Limitation on Designations of Unrestricted
  Subsidiaries" below, the Fair Market Value of the Company's interest in
  such Subsidiary, provided that such amount shall not in any case exceed the
  Designation Amount with respect to such Restricted Subsidiary upon its
  Designation,
 
  minus:
 
  the Designation Amount (measured as of the date of Designation) with
  respect to any Restricted Subsidiary of the Company which has been
  designated as an Unrestricted Subsidiary after May 22, 1998 in accordance
  with "--Limitations on Designations of Unrestricted Subsidiaries" below.
 
  For purposes of the preceding clause (C)(4), the value of the aggregate net
proceeds received by the Company upon the issuance of Capital Stock upon the
exercise of options, warrants or rights will be the net cash proceeds received
upon the issuance of such options, warrants or rights plus the incremental
amount received by the Company upon the exercise thereof.
 
  None of the foregoing provisions will prohibit, so long, in the case of
clauses (ii), (iii), (v), (vi) and (vii) below, as there is no Default or
Event of Default continuing, (i) the payment of any dividend or distribution
within 60 days after the date of its declaration, if at the date of
declaration such payment would be permitted by the first paragraph of this
covenant; (ii) the redemption, repurchase or other acquisition or retirement
of any shares of any class of Capital Stock of the Company in exchange for, or
out of the net cash proceeds of, a substantially concurrent issue and sale of
other shares of Capital Stock of the Company (other than Redeemable Capital
Stock) to any person (other than to a Subsidiary of the Company); provided,
however, that such net cash proceeds are excluded from clause (C) of the first
paragraph of this covenant; (iii) any redemption, repurchase or other
acquisition or retirement of Subordinated Indebtedness by exchange for, or out
of the net cash proceeds of, a substantially concurrent issue and sale of (1)
Capital Stock (other than Redeemable Capital Stock) of the Company to any
person (other than to a Subsidiary of the Company); provided, however, that
any such net cash proceeds are excluded from clause (C) of the first paragraph
of this covenant; or (2) Indebtedness of the Company so long as such
Indebtedness is Subordinated Indebtedness which (w) has no scheduled principal
payment prior to the 91st day after the Maturity Date, (x) has an Average Life
to Stated Maturity greater than the remaining Average Life to Stated Maturity
of the Notes and (y) is subordinated to the Notes in the same manner and to
the same extent as the Subordinated Indebtedness so purchased, exchanged,
redeemed, acquired or retired; (iv) Investments constituting Restricted

obligations in respect of goods to be delivered to, services (including
management and consulting services) performed for and properties used by, the
Company and its Restricted Subsidiaries, (3) the purchase price for
Investments in other persons, provided that promptly following such Investment
either (x) such other person either becomes a Restricted Subsidiary or is
merged or consolidated with, or transfers or conveys all or substantially all
of its assets to, the Company or a Restricted Subsidiary, or (y) such
Investment would otherwise be permitted under the Indenture if made by the

to clauses (i), (v), (vi) or (vii) of this paragraph shall be taken into

May 22, 1998.
 
  Limitation on Liens. The Company will not, and will not permit any of its
Restricted Subsidiaries to, create, incur, assume or suffer to exist any Liens
of any kind against or upon any of its property or assets, or any proceeds
therefrom, unless the Notes are equally and ratably secured (except that Liens
securing Subordinated Indebtedness shall be expressly subordinate to Liens
securing the Notes to the same extent such Subordinated Indebtedness is
subordinate to the Notes), except for (a) Liens securing Senior Indebtedness;
(b) Liens securing the Notes; (c) Liens in favor of the Company on assets of
any Subsidiary of the Company; (d) Liens securing Indebtedness which is
incurred to refinance Indebtedness which has been secured by a Lien permitted
under the Indenture and which has been incurred in accordance with the
provisions of the Indenture; provided, however, that such Liens do not extend
to or cover any property or assets of the Company or any its Restricted
Subsidiaries not securing the Indebtedness so refinanced; and (e) Permitted
Liens.
 
  Disposition of Proceeds of Asset Sales. The Company will not, and will not
permit any of its Restricted Subsidiaries to, make any Asset Sale unless (a)
the Company or such Restricted Subsidiary, as the case may be, receives
consideration at the time of such Asset Sale at least equal to the Fair Market
Value of the shares or assets sold or otherwise disposed of and (b) at least
75% of such consideration consists of cash or Cash Equivalents or Replacement
Assets; provided, however, that the amount of any liabilities (as shown on the
most recent balance sheet of the Company or such Restricted Subsidiary) of the
Company or such Restricted Subsidiary that are assumed by the transferee of
such assets and any securities, notes or other obligations received by the
Company or such Restricted Subsidiary from such transferee that are converted
within 30 days into cash or Cash Equivalents (to the extent of the cash or
Cash Equivalents received) shall be deemed to be cash for the purposes of this
provision; provided further, that the 75% limitation referred to in clause (b)
will not apply to any Asset Sale in which the cash or Cash Equivalent portion
of the consideration received therefrom, determined in accordance with the
foregoing provision, is equal to or greater than what the after-tax proceeds
would have been had such Asset Sale complied with the aforementioned 75%
limitation. To the extent that the Net Cash Proceeds of any Asset Sale are not
required to be applied to repay, and permanently reduce the commitments under,
Senior Indebtedness of the Company, or are not so applied, the Company or such
Restricted Subsidiary, as the case may be, may apply the Net Cash Proceeds
from such Asset Sale, within 360 days of such Asset Sale, to an investment in
properties and assets that replace the properties and assets that were the
subject of such Asset Sale or in properties and assets that are used or useful
in the business of the Company and its Restricted Subsidiaries conducted at
such time or in businesses reasonably related thereto or in Capital Stock of a
person, the principal portion of whose assets consist of such property or
assets ("Replacement Assets"). Any Net Cash Proceeds from any Asset Sale that
are neither used to repay, and permanently reduce the commitments under,
Senior Indebtedness nor invested in Replacement Assets within such 360-day
period constitute "Excess Proceeds" subject to disposition as provided below.
 
  When the aggregate amount of Excess Proceeds equals or exceeds $10 million,
the Company shall make an offer to purchase (an "Asset Sale Offer"), from all
holders of the Notes, an aggregate principal amount of Notes equal to such
Excess Proceeds, at a price in cash equal to 100% of the outstanding principal
amount thereof plus accrued and unpaid interest, if any, to the purchase date
(the "Asset Sale Offer Price"). To the extent that the
 
                                      42
<PAGE>
 
aggregate principal amount of Notes tendered pursuant to an Asset Sale Offer
is less than the Excess Proceeds, the Company may use such deficiency for
general corporate purposes. The Notes shall be purchased by the Company, at
the option of the holder thereof, in whole or in part in integral multiples of
$1,000, on a date that is not earlier than 30 days and not later than 60 days
from the date the notice is given to holders, or such later date as may be
necessary for the Company to comply with the requirements under the Exchange
Act. If the aggregate principal amount of Notes validly tendered and not
withdrawn by holders thereof exceeds the Excess Proceeds, Notes to be
purchased will be selected on a pro rata basis. Notwithstanding the foregoing,
if the Company is required to commence an Asset Sale Offer at any time when
securities of the Company ranking pari passu in right of payment with the
Notes are outstanding and the terms of such securities provide that a similar
offer must be made with respect to such other securities, then the Asset Sale
Offer for the Notes shall be made concurrently with such other offers and
securities of each issue will be accepted on a pro rata basis in proportion to
the aggregate principal amount of securities of each issue which the holders
thereof elect to have purchased. Any Asset Sale Offer will be made only to the
extent permitted under, and subject to prior compliance with, the terms of
agreements governing Senior Indebtedness. Upon completion of such Asset Sale
Offer, the amount of Excess Proceeds shall be reset to zero.
 
  The Company will comply with Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder, to the extent such laws and
regulations are applicable, in the event that an Asset Sale occurs and the
Company is required to purchase Notes as described above.
 
  Limitation on Preferred Stock of Restricted Subsidiaries. The Company will
not permit any Restricted Subsidiary to issue any Preferred Stock other than
Preferred Stock issued to the Company or a Wholly-Owned Restricted Subsidiary.
The Company will not sell, transfer or otherwise dispose of Preferred Stock
issued by a Restricted Subsidiary of the Company or permit a Restricted
Subsidiary to sell, transfer or otherwise dispose of Preferred Stock issued by
a Restricted Subsidiary, other than to the Company or a Wholly-Owned
Restricted Subsidiary. Notwithstanding the foregoing, nothing in such covenant
will prohibit Preferred Stock (other than Redeemable Capital Stock) issued by
a person prior to the time (A) such person becomes a Restricted Subsidiary of
the Company, (B) such person merges with or into a Restricted Subsidiary of
the Company or (C) a Restricted Subsidiary of the Company merges with or into
such person; provided that such Preferred Stock was not issued or incurred by
such person in anticipation of a transaction contemplated by subclause (A),
(B), or (C) above.
 
  Limitation on Transactions with Affiliates. The Company will not, and will
not permit any of its Restricted Subsidiaries to, directly or indirectly,
enter into any transaction or series of related transactions (including,
without limitation, the sale, transfer, disposition, purchase, exchange or
lease of assets, property or services) with, or for the benefit of, any of its
Affiliates (other than Restricted Subsidiaries), except (a) on terms that are
no less favorable to the Company or such Subsidiary, as the case may be, than
those which could have been obtained in a comparable transaction at such time
from persons who are not Affiliates of the Company, (b) with respect to a
transaction or series of related transactions involving aggregate payments or
value equal to or greater than $2 million, the Company shall have delivered an
officer's certificate to the Trustee certifying that such transaction or
transactions comply with the preceding clause (a), and (c) with respect to a
transaction or series of related transactions involving aggregate payments or
value equal to or greater than $5 million, such transaction or transactions
shall have been approved by a majority of the Disinterested Members of the
Board of Directors of the Company.
 
  Notwithstanding the foregoing, the restrictions set forth in this covenant
shall not apply to (i) transactions with or among the Company and the
Restricted Subsidiaries, (ii) customary directors' fees, indemnification and
similar arrangements, consulting fees, employee salaries, bonuses or
employment agreements, compensation or employee benefit arrangements and
incentive arrangements with any officer, director or employee of the Company
or any Restricted Subsidiary entered into in the ordinary course of business,
(iii) any dividends made in compliance with "--Limitation on Restricted
Payments" above, (iv) loans and advances to officers, directors and employees
of the Company or any Restricted Subsidiary for travel, entertainment, moving
and other relocation expenses, in each case made in the ordinary course of
business, (v) the incurrence of intercompany
 
                                      43
<PAGE>
 
Indebtedness which constitutes Permitted Indebtedness, (vi) transactions
pursuant to agreements in effect on the Issue Date, (vii) the purchase of
equipment for its Fair Market Value from Terex Corporation or its Affiliates
in the ordinary course of business of each of Terex Corporation and the
Company and (viii) transactions described in or permitted by clauses (vii) and
(viii) of the last paragraph under the caption "--Limitation on Restricted
Payments."
 
  Limitation on Dividends and other Payment Restrictions Affecting Restricted
Subsidiaries. The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer
to exist or become effective any consensual encumbrance or restriction on the
ability of any Restricted Subsidiary of the Company to (a) pay dividends, in
cash or otherwise, or make any other distributions on or in respect of its
Capital Stock or any other interest or participation in, or measured by, its
profits, (b) pay any Indebtedness owed to the Company or any other Restricted
Subsidiary of the Company, (c) make loans or advances to the Company or any
other Restricted Subsidiary of the Company, (d) transfer any of its properties
or assets to the Company or any other Restricted Subsidiary of the Company or
(e) guarantee any Indebtedness of the Company or any other Restricted
Subsidiary of the Company, except for such encumbrances or restrictions
existing under or by reason of (i) applicable law or any applicable rule,
regulation or order, (ii) customary non-assignment provisions of any contract
or any lease governing a leasehold interest of the Company or any Restricted
Subsidiary of the Company, (iii) customary restrictions on transfers of
property subject to a Lien permitted under the Indenture, (iv) the Credit
Facility and the Term Loan as in effect on the Issue Date, (v) any agreement
or other instrument of a person acquired by the Company or any Restricted
Subsidiary of the Company in existence at the time of such acquisition (but
not created in contemplation thereof), which encumbrance or restriction is not
applicable to any person, or the properties or assets of any person, other
than the person, or the property or assets of the person, so acquired, (vi) an
agreement entered into for the sale or disposition of Capital Stock or assets
of a Restricted Subsidiary or an agreement entered into for the sale of
specified assets (in either case, so long as such encumbrance or restriction,
by its terms, terminates on the earlier of the termination of such agreement
or the consummation of such agreement and so long as such restriction applies
only to the Capital Stock or assets to be sold), (vii) any agreement in effect
on the Issue Date, (viii) the Indenture and the Guarantees, (ix) the
indentures governing the 9 1/2% Notes and the 8.80% Notes and (x) any
agreement that amends, extends, refinances, renews or replaces any agreement
described in the foregoing clauses, provided that the terms and conditions of
any such agreement are not materially less favorable to the holders of the
Notes with respect to such dividend and payment restrictions than those under
or pursuant to the agreement amended, extended, refinanced, renewed or
replaced.
 
  Limitation on Designations of Unrestricted Subsidiaries. The Company may
designate after the Issue Date any Restricted Subsidiary as an "Unrestricted
Subsidiary" under the Indenture (a "Designation") only if:
 
    (i) no Default shall have occurred and be continuing at the time of or
  after giving effect to such Designation;
 
    (ii) the Company would be permitted to make an Investment (other than a
  Permitted Investment, except a Permitted Investment covered by clause (x)
  of the definition thereof) at the time of Designation (assuming the
  effectiveness of such Designation) pursuant to the first paragraph of "--
  Limitation on Restricted Payments" above in an amount (the "Designation
  Amount") equal to the Fair Market Value of the Company's interest in such
  Subsidiary on such date calculated in accordance with GAAP; and
 
    (iii) the Company would be permitted under the Indenture to incur $1.00
  of additional Indebtedness (other than Permitted Indebtedness) pursuant to
  the covenant described under "--Limitation on Indebtedness" at the time of
  such Designation (assuming the effectiveness of such Designation).
 
  In the event of any such Designation, the Company shall be deemed to have
made an Investment constituting a Restricted Payment pursuant to the covenant
"--Limitation on Restricted Payments" for all purposes of the Indenture in the
Designation Amount.
 
 
                                      44
<PAGE>
 
  The Company shall not, and shall not cause or permit any Restricted
Subsidiary to, at any time (x) provide credit support for or subject any of
its property or assets (other than the Capital Stock of any Unrestricted
Subsidiary) to the satisfaction of, any Indebtedness of any Unrestricted
Subsidiary (including any undertaking, agreement or instrument evidencing such
Indebtedness), (y) be directly or indirectly liable for any Indebtedness of
any Unrestricted Subsidiary or (z) be directly or indirectly liable for any
Indebtedness which provides that the holder thereof may (upon notice, lapse of
time or both) declare a default thereon or cause the payment thereof to be
accelerated or payable prior to its final scheduled maturity upon the
occurrence of a default with respect to any Indebtedness of any Unrestricted
Subsidiary (including any right to take enforcement action against such
Unrestricted Subsidiary), except any non-recourse guarantee given solely to
support the pledge by the Company or any Restricted Subsidiary of the Capital
Stock of an Unrestricted Subsidiary. All Subsidiaries of Unrestricted
Subsidiaries shall automatically be deemed to be Unrestricted Subsidiaries.
 
  The Company may revoke any Designation of a Subsidiary as an Unrestricted
Subsidiary (a "Revocation") if:
 
    (i) no Default shall have occurred and be continuing at the time of and
  after giving effect to such Revocation; and
 
    (ii) all Liens and Indebtedness of such Unrestricted Subsidiary
  outstanding immediately following such Revocation would, if incurred at
  such time, have been permitted to be incurred for all purposes of the
  Indenture.
 
  In the event the Company or a Restricted Subsidiary makes any Investment in
any person which was not previously a Subsidiary and such person thereby
becomes a Subsidiary, such person shall automatically be an Unrestricted
Subsidiary and the Company may designate such Subsidiary as a Restricted
Subsidiary only if it meets the foregoing requirements.
 
  All Designations and Revocations must be evidenced by Board Resolutions of
the Company delivered to the Trustee certifying compliance with the foregoing
provisions.
 
  Limitation on the Issuance of Subordinated Indebtedness. The Company will
not, directly or indirectly, incur any Indebtedness (including Acquired
Indebtedness) that is subordinate in right of payment to any Indebtedness of
the Company and senior in right of payment to the Notes.
 
  Additional Subsidiary Guarantees. If the Company or any of its Restricted
Subsidiaries acquires, creates or designates another domestic Restricted
Subsidiary, then such newly acquired, created or designated Restricted
Subsidiary shall, within 30 days after the date of its acquisition, creation
or designation, whichever is later, execute and deliver to the Trustee a
supplemental indenture in form reasonably satisfactory to the Trustee pursuant
to which such Subsidiary shall unconditionally guarantee all of the Company's
obligations under the Notes and the Indenture on the terms set forth in the
Indenture. Thereafter, such Subsidiary shall be a Guarantor for all purposes
of the Indenture.
 
  Reporting Requirements. For so long as the Notes are outstanding, whether or
not the Company is subject to Section 13(a) or 15(d) of the Exchange Act, or
any successor provision thereto, the Company shall file with the Commission
(if permitted by Commission practice and applicable law and regulations) the
annual reports, quarterly reports and other documents which the Company would
have been required to file with the Commission pursuant to such Section 13(a)
or 15(d) or any successor provision thereto if the Company were so subject,
such documents to be filed with the Commission on or prior to the respective
dates (the "Required Filing Dates") by which the Company would have been
required so to file such documents if the Company were so subject. If,
notwithstanding the preceding sentence, filing such documents by the Company
with the Commission is not permitted by Commission practice or applicable law
or regulations, the Company shall transmit (or cause to be transmitted) by
mail to all holders of Notes, as their names and addresses appear in the Note
register, copies of such documents within 15 days after the Required Filing
Date. In addition, for so long as any Notes remain outstanding, the Company
will furnish to the holders of Notes and to securities analysts and
prospective

investors, upon their request, the information required to be delivered
pursuant to Rule 144A(d)(4) under the Securities Act, and, to any beneficial
holder of Notes, if not obtainable from the Commission, information of the
type that would be filed with the Commission pursuant to the foregoing
provisions upon the request of any such holder.
 
CONSOLIDATION, MERGER, SALE OF ASSETS, ETC.
 
  The Company will not, in any transaction or series of transactions, merge or
consolidate with or into, or sell, assign, convey, transfer, lease or
otherwise dispose of all or substantially all of its properties and assets as
an entirety to, any person or persons, and the Company will not permit any of
its Restricted Subsidiaries to enter into any such transaction or series of
transactions if such transaction or series of transactions, in the aggregate,
would result in a sale, assignment, conveyance, transfer, lease or other
disposition of all or substantially all of the properties and assets of the
Company or the Company and its Restricted Subsidiaries, taken as a whole, to
any other person or persons, unless at the time and after giving effect
thereto (a) either (i) if the transaction or transactions is a merger or
consolidation, the Company or such Restricted Subsidiary, as the case may be,
shall be the surviving person of such merger or consolidation, or (ii) the
person formed by such consolidation or into which the Company, or such
Restricted Subsidiary, as the case may be, is merged or to which the
properties and assets of the Company or such Restricted Subsidiary, as the
case may be, substantially as an entirety, are transferred (any such surviving
person or transferee person being the "Surviving Entity") shall be a
corporation organized and existing under the laws of the United States of
America, any state thereof or the District of Columbia and shall expressly
assume by a supplemental indenture executed and delivered to the Trustee, in
form satisfactory to the Trustee, all the obligations of the Company or such
Restricted Subsidiary, as the case may be, under the Notes, the Indenture and
the Registration Rights Agreement, and in each case, the Indenture shall
remain in full force and effect; (b) immediately after giving effect to such
transaction or series of transactions on a pro forma basis (including, without
limitation, any Indebtedness incurred or anticipated to be incurred in
connection with or in respect of such transaction or series of transactions),
no Default or Event of Default shall have occurred and be continuing; and (c)
except in the case of any merger of the Company with any wholly-owned
Subsidiary of the Company or any merger of Guarantors (and, in each case, no
other persons), the Company or the Surviving Entity, as the case may be, after
giving effect to such transaction or series of transactions on a pro forma
basis (including, without limitation, any Indebtedness incurred or anticipated
to be incurred in connection with or in respect of such transaction or series
of transactions), could incur $1.00 of additional Indebtedness (other than
Permitted Indebtedness) (assuming a market rate of interest with respect to
such additional Indebtedness).
 
  In connection with any consolidation, merger, transfer, lease, assignment or
other disposition contemplated hereby, the Company shall deliver, or cause to
be delivered, to the Trustee, in form and substance reasonably satisfactory to
the Trustee, an officers' certificate and an opinion of counsel, each stating
that such consolidation, merger, transfer, lease, assignment or other
disposition and the supplemental indenture in respect thereof comply with the
requirements under the Indenture.
 
  Upon any consolidation or merger, or any sale, assignment, conveyance,
transfer, lease or disposition of all or substantially all of the properties
and asset of the Company in accordance with the immediately preceding
paragraphs, the successor person formed by such consolidation or into which
the Company or a Restricted Subsidiary, as the case may be, is merged or the
successor person to which such sale, assignment, conveyance, transfer, lease
or disposition is made shall succeed to, and be substituted for, and may
exercise every right and power of the Company under the Notes, the Indenture
and/or the Registration Rights Agreement, as the case may be, with the same
effect as if such successor had been named as the Company in the Notes, the
Indenture and/or in the Registration Rights Agreement, as the case may be and,
except in the case of a lease, the Company or such Restricted Subsidiary shall
be released and discharged from its obligations thereunder.
 
  The Indenture provides that for all purposes of the Indenture and the Notes
(including the provision of this covenant and the covenants described in "--
Certain Covenants--Limitation on Indebtedness," "--Limitation on Restricted
Payments," and "--Limitation on Liens"), Subsidiaries of any surviving person
shall, upon such
 
                                      46
<PAGE>
 
transaction or series of related transactions, become Restricted Subsidiaries
unless and until designated Unrestricted Subsidiaries pursuant to and in
accordance with "--Limitation on Designations of Unrestricted Subsidiaries"
and all Indebtedness, and all Liens on property or assets, of the Company and
the Restricted Subsidiaries in existence immediately after such transaction or
series of related transactions will be deemed to have been incurred upon such
transaction or series of related transactions.

  Guarantor in accordance with the terms of the Indenture).
 
  If an Event of Default (other than those covered by clause (vii) or (viii)
above with respect to the Company) shall occur and be continuing, the Trustee,
by notice to the Company and the representatives of the holders of Designated
Senior Indebtedness, or the holders of at least 25% in aggregate principal
amount of the Notes then outstanding, by notice to the Trustee, the Company
and the representatives of the holders of Designated Senior Indebtedness, may

notice to the representative of the holders of Designated Senior Indebtedness.
If an Event of Default specified in clause (vii) or (viii) above with respect
to the Company occurs and is continuing, then the principal of, premium, if
any, and accrued and unpaid interest, if any, on all the outstanding Notes
shall ipso facto become and be immediately due and payable without any

  After a declaration of acceleration under the Indenture, but before a
judgment or decree for payment of the money due has been obtained by the
Trustee, the holders of a majority in aggregate principal amount of the
outstanding Notes, by written notice to the Company and the Trustee, may
rescind such declaration if (a) the Company has paid or deposited with the
Trustee a sum sufficient to pay (i) all sums paid or advanced by the Trustee
under the Indenture and the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, (ii) all overdue interest
on all Notes, (iii) the principal of and premium, if any, on any Notes which
have become due otherwise than by such declaration of acceleration and
interest thereon at the rate borne by the Notes, and (iv) to the extent that
payment of such interest is lawful, interest upon overdue interest and overdue
principal at the rate borne by the Notes which has become due otherwise than
by such declaration of acceleration; (b) the rescission would not conflict
with any judgment or decree of a court of competent jurisdiction; and (c) all
Events of Default, other than the non-payment of principal of, premium, if
any, and interest on the Notes that has become due solely by such declaration
of acceleration, have been cured or waived.
 
  The holders of not less than a majority in aggregate principal amount of the
outstanding Notes may on behalf of the holders of all the Notes waive any past
defaults under the Indenture, except a default in the payment of the principal
of, premium, if any, or interest on any Note, or in respect of a covenant or
provision which under the Indenture cannot be modified or amended without the
consent of the holder of each Note outstanding.
 
  No holder of any of the Notes has any right to institute any proceeding with
respect to the Indenture or any remedy thereunder, unless the holders of at
least 25% in aggregate principal amount of the outstanding Notes
 
                                      48
<PAGE>
 
have made written request, and offered reasonable indemnity, to the Trustee to
institute such proceeding as Trustee under the Notes and the Indenture, the
Trustee has failed to institute such proceeding within 45 days after receipt
of such notice and the Trustee, within such 45-day period, has not received
directions inconsistent with such written request by holders of a majority in
aggregate principal amount of the outstanding Notes. Such limitations do not
apply, however, to a suit instituted by a holder of a Note for the enforcement
of the payment of the principal of, premium, if any, or interest on such Note
on or after the respective due dates expressed in such Note.
 
  During the existence of an Event of Default, the Trustee is required to
exercise such rights and powers vested in it under the Indenture and use the
same degree of care and skill in its exercise thereof as a prudent person
would exercise under the circumstances in the conduct of such person's own
affairs. Subject to the provisions of the Indenture relating to the duties of
the Trustee, whether or not an Event of Default shall occur and be continuing,
the Trustee under the Indenture is not under any obligation to exercise any of
its rights or powers under the Indenture at the request or direction of any of
the holders unless such holders shall have offered to the Trustee reasonable
security or indemnity. Subject to certain provisions concerning the rights of
the Trustee, the holders of a majority in aggregate principal amount of the
outstanding Notes have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee under the Indenture.
 
  If a Default or an Event of Default occurs and is continuing and is known to
the Trustee, the Trustee shall mail to each holder of the Notes notice of the
Default or Event of Default within 30 days after obtaining knowledge thereof.
Except in the case of a Default or an Event of Default in payment of principal
of, premium, if any, or interest on any Notes, the Trustee may withhold the
notice to the holders of such Notes if a committee of its trust officers in
good faith determines that withholding the notice is in the interest of the
Noteholders.
 
  The Company is required to furnish to the Trustee annual and quarterly
statements as to the performance by the Company of its obligations under the
Indenture and as to any default in such performance. The Company is also
required to notify the Trustee within five days of any event which is, or
after notice or lapse of time or both would become, an Event of Default.
 
NO LIABILITY FOR CERTAIN PERSONS
 
  No director, officer, employee or stockholder of Holdings or the Company,
nor any director, officer or employee of any Guarantor, as such, will have any
liability for any obligations of the Company or any Guarantor under the Notes,
the Guarantees or the Indenture based on or by reason of such obligations or
their creation. Each holder by accepting a Note waives and releases all such
liability. The foregoing waiver and release are an integral part of the
consideration for the issuance of the Notes. Such waiver may not be effective
to waive liabilities under the federal securities laws.
 
DEFEASANCE OR COVENANT DEFEASANCE OF INDENTURE
 
  The Company may, at its option and at any time, terminate the obligations of
the Company with respect to the outstanding Notes ("defeasance") to the extent
set forth below. Such defeasance means that the Company shall be deemed to
have paid and discharged the entire Indebtedness represented by the
outstanding Notes, except for (i) the rights of holders of outstanding Notes
to receive payment in respect of the principal of, premium, if any, and
interest on such Notes when such payments are due, (ii) the Company's
obligations to issue temporary Notes, register the transfer or exchange of any
Notes, replace mutilated, destroyed, lost or stolen Notes and maintain an
office or agency for payments in respect of the Notes, (iii) the rights,
powers, trusts, duties and immunities of the Trustee, and (iv) the defeasance
provisions of the Indenture. In addition, the Company may, at its option and
at any time, elect to terminate the obligations of the Company with respect to
certain covenants that are set forth in the Indenture, some of which are
described under "--Certain Covenants" above, and any subsequent failure to
comply with such obligations shall not constitute a Default or an Event of
Default with respect to the Notes ("covenant defeasance").
 
                                      49
<PAGE>
 
  In order to exercise either defeasance or covenant defeasance, (i) the
Company must irrevocably deposit with the Trustee, in trust, for the benefit
of the holders of the Notes, cash in United States dollars, U.S. Government
Obligations (as defined in the Indenture), or a combination thereof, in such
amounts as will be sufficient, in the opinion of a nationally recognized firm
of independent public accountants, to pay the principal of, premium, if any,
and interest on the outstanding Notes to redemption or maturity (except lost,
stolen or destroyed Notes which have been replaced or paid); (ii) the Company
shall have delivered to the Trustee an opinion of counsel to the effect that
the holders of the outstanding Notes will not recognize income, gain or loss
for federal income tax purposes as a result of such defeasance or covenant
defeasance and will be subject to federal income tax on the same amounts, in
the same manner and at the same times as would have been the case if such
defeasance or covenant defeasance had not occurred (in the case of defeasance,
such opinion must refer to and be based upon a ruling of the Internal Revenue
Service or a change in applicable federal income tax laws); (iii) no Default
or Event of Default shall have occurred and be continuing on the date of such
deposit (other than a default under the Indenture caused by the incurrence of
Indebtedness to make such deposit); (iv) such defeasance or covenant
defeasance shall not cause the Trustee to have a conflicting interest with
respect to any securities of the Company; (v) such defeasance or covenant
defeasance shall not result in a breach or violation of, or constitute a
default under, any agreement or instrument to which the Company is a party or
by which it is bound (other than a default under the Indenture caused by the
incurrence of Indebtedness to make such deposit); (vi) the Company shall have
delivered to the Trustee an opinion of counsel to the effect that after the
91st day following the deposit, the trust funds will not be subject to the
effect of any applicable bankruptcy, insolvency, reorganization or similar
laws affecting creditors' rights generally; (vii) the Company shall have
delivered to the Trustee an officers' certificate stating that the deposit was
not made by the Company with the intent of preferring the holders of the Notes
over the other creditors of the Company with the intent of hindering, delaying
or defrauding creditors of the Company or others; (viii) no event or condition
shall exist that would prevent the Company from making payments of the
principal of, premium, if any, and interest on the Notes on the date of such
deposit or at any time ending on the 91st day after the date of such deposit;
and (ix) the Company shall have delivered to the Trustee an officers'
certificate and an opinion of counsel, each stating that all conditions
precedent under the Indenture to either defeasance or covenant defeasance, as
the case may be, have been complied with.
 
SATISFACTION AND DISCHARGE
 
  The Indenture will be discharged and will cease to be of further effect
(except as to surviving rights or registration of transfer or exchange of the
Notes, as expressly provided for in the Indenture) as to all outstanding Notes
when (i) either (a) all the Notes theretofore authenticated and delivered
(except lost, stolen or destroyed Notes which have been replaced or repaid and
Notes for whose payment money has theretofore been deposited in trust or
segregated and held in trust by the Company and thereafter repaid to the
Company or discharged from such trust) have been delivered to the Trustee for
cancellation or (b) all Notes not theretofore delivered to the Trustee for
cancellation (except lost, stolen or destroyed Notes which have been replaced
or paid) have become due and payable and the Company has irrevocably deposited
or caused to be deposited with the Trustee funds in an amount sufficient to
pay and discharge the entire Indebtedness on the Notes not theretofore
delivered to the Trustee for cancellation, for principal of, premium, if any,
and interest on the Notes to the date of deposit together with irrevocable
instructions from the Company directing the Trustee to apply such funds to the
payment thereof at maturity or redemption, as the case may be; (ii) the
Company has paid all other sums payable under the Indenture by the Company;
and (iii) the Company has delivered to the Trustee an officers' certificate
and an opinion of counsel stating that all conditions precedent under the
Indenture relating to the satisfaction and discharge of the Indenture have
been complied with.
 
AMENDMENTS AND WAIVERS
 
  From time to time, the Company, when authorized by a resolution of its Board
of Directors, and the Trustee may, without the consent of the holders of any
outstanding Notes, amend, waive or supplement the Indenture or the Notes for
certain specified purposes, including, among other things, curing ambiguities,
defects or
 
                                      50
<PAGE>
 
inconsistencies, qualifying, or maintaining the qualification of, the
Indenture under the Trust Indenture Act, or making any change that does not
adversely affect the rights of any holder of Notes. Other amendments and
modifications of the Indenture or the Notes may be made by the Company and the
Trustee with the consent of the holders of not less than a majority of the
aggregate principal amount of the outstanding Notes; provided, however, that
no such modification or amendment may, without the consent of the holder of
each outstanding Note affected thereby, (i) reduce the principal amount of,
extend the fixed maturity of or alter the redemption provisions of, the Notes,
(ii) change the currency in which any Notes or any premium or the interest
thereon is payable, (iii) reduce the percentage in principal amount of
outstanding Notes that must consent to an amendment, supplement or waiver or
consent to take any action under the Indenture or the Notes, (iv) impair the
right to institute suit for the enforcement of any payment on or with respect
to the Notes, (v) waive a default in payment with respect to the Notes, (vi)
amend, change or modify the obligation of the Company to make and consummate a
Change of Control Offer in the event of a Change of Control or make and
consummate the offer with respect to any Asset Sale or modify any of the
provisions or definitions with respect thereto, (vii) reduce or change the
rate or time for payment of interest on the Notes or (viii) to modify or
change any provision of the Indenture affecting the ranking of the Notes in a
manner adverse to the holders of the Notes.
 
THE TRUSTEE
 
  The Indenture provides that, except during the continuance of an Event of
Default, the Trustee thereunder will perform only such duties as are
specifically set forth in the Indenture. If an Event of Default has occurred
and is continuing, the Trustee will exercise such rights and powers vested in
it under the Indenture and use the same degree of care and skill in its
exercise as a prudent person would exercise under the circumstances in the
conduct of such person's own affairs.
 
  The Indenture and provisions of the Trust Indenture Act incorporated by
reference therein contain limitations on the rights of the Trustee thereunder,
should it become a creditor of the Company, to obtain payment of claims in
certain cases or to realize on certain property received by it in respect of
any such claims, as security or otherwise. The Trustee is permitted to engage
in other transactions; provided, however, that if it acquires any conflicting
interest (as defined in such Act) it must eliminate such conflict or resign.

Charges" for purposes of determining the denominator (but not the numerator)

optionally be determined at an interest rate based upon a factor of a prime or
similar rate, a eurocurrency interbank offered rate, or other rates, then the

effect during the Four Quarter Period. If such person or any of its Restricted

instrument, judgment, decree, order, statute, rule or governmental regulations
applicable to that Restricted Subsidiary or its stockholders and (vi) any gain
or loss realized as a result of the cumulative effect of a change in
accounting principles.

its Restricted Subsidiaries or in the notes thereto, excluding, however, in

BOOK-ENTRY; DELIVERY AND FORM
 
  The Original Notes are represented by three permanent, global notes (the
"Original Global Securities"), in definitive, fully registered book-entry
form, and the Exchange Notes will be represented by three, permanent global
notes (the "Exchange Global Securities"), in definitive, fully registered
book-entry form. The Original Global Securities are, and the Exchange Global
Securities will be, registered in the name of a nominee of DTC. Pursuant to
procedures established by DTC, interests in the Original Global Securities and
the Exchange Global Securities (collectively, the "Global Securities") will be
shown on, and the transfer of such interest will be effected only through,
records maintained by DTC or its nominee (with respect to interest of
Participants) and the records of Participants (with respect to interests of
persons other than Participants).
 
  So long as DTC or its nominee is the registered owner or holder of the
Global Securities, DTC or such nominee will be considered the sole owner or
holder of the Notes represented by the Global Securities for all purposes
under the Indenture and under the Notes represented thereby. No beneficial
owner of an interest in the Global Securities will be able to transfer such
interest except in accordance with the applicable procedures of DTC in
addition to those provided for under the Indenture. The laws of some states
require that certain persons take physical delivery in definitive form of
securities that they own. Consequently, the ability to transfer beneficial
interest in a Global Security to such persons will be limited to that extent.
Because DTC can act only on behalf of Participants, which in turn act on
behalf of Indirect Participants (as defined herein), the ability of a person
having beneficial interests in a Global Security to pledge such interests to
persons or entities that do not participate in the DTC system, or otherwise
take actions in respect of such interests, may be affected by the lack of a
physical certificate evidencing such interests.
 
  Payments of the principal of, premium, if any, and interest on the Notes
represented by the Global Securities will be made to DTC or its nominee, as
the case may be, as the registered owner thereof. None of the Company, the
Trustee or any paying agent under the Indenture will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests in the Global Securities or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interest.
 
  The Company expects that DTC or its nominee, upon receipt of any payment of
the principal of, premium, if any, and interest on the Notes represented by
the Global Securities, will credit Participants' accounts with payments in
amounts proportionate to their respective beneficial interests in the Global
Securities as shown in the records of DTC or its nominee. The Company also
expects that payments by Participants to owners of beneficial interests in the
Global Securities held through such Participants will be governed by standing
instructions and customary practice as is now the case with securities held
for the accounts of customers registered in the names of nominees for such
customers. Such payment will be the responsibility of such Participants.
 
                                      62

  DTC has advised the Company that DTC will take any action permitted to be
taken by a Holder of Notes (including the presentation of Notes for exchange
as described below) only at the direction of one or more Participants to whose
account the DTC interests in the Global Securities are credited and only in
respect of the aggregate principal amount as to which such Participant or
Participants has or have given such direction. However, if there is an Event
of Default under the Indenture, DTC will exchange the Global Securities for
certificated securities, which it will distribute to its Participants.
 
  DTC has advised the Company as follows: DTC is a limited purpose trust
company organized under the laws of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the
Uniform Commercial Code and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. DTC was created to hold
securities for its Participants and facilitate the clearance and settlement of
securities transactions between Participants through electronic book-entry
changes in accounts of its Participants, thereby eliminating the need for
physical movement of certificates. Participants include securities brokers and
dealers, banks, trust companies and clearing corporations and certain other
organizations. Indirect access to the DTC system is available to others such
as banks, brokers, dealers and trust companies that clear through or maintain
a custodial relationship with a Participant, either directly or indirectly.
 
  Although DTC is expected to follow the foregoing procedures in order to
facilitate transfers of interests in the Global Securities among Participants
of DTC it is under no obligation to perform such procedures, and such
procedures may be discontinued at any time. Neither the Company nor the
Trustee will have any responsibility for the performance by DTC or its direct
or indirect participants of their respective obligations under the rules and
procedures governing their operations.
 
  Interests in the Global Securities will be exchanged for certificated
securities if (i) DTC notifies the Company that it is unwilling or unable to
continue as depositary for the Global Securities, or DTC ceases to be a
"Clearing Agency" registered under the Exchange Act, and a successor
depositary is not appointed by the Company within 90 days, or (ii) an Event of
Default has occurred and is continuing with respect to the Notes. Upon the
occurrence of any of the events described in the preceding sentence, the
Company will cause the appropriate certificated securities to be delivered.

                             PLAN OF DISTRIBUTION
 
  Any broker-dealer (a "Participating Broker-Dealer") that, pursuant to the
Exchange Offer, receives Exchange Notes in exchange for Original Notes that
were acquired by it for its own account as a result of market-making
activities or other trading activities, will be required to deliver a
prospectus meeting the requirements of the Securities Act in connection with
any resales by it of any such Exchange Notes. Each Participating Broker-Dealer
will be required to acknowledge in the Letter of Transmittal that it will
comply with such prospectus delivery requirement in connection with any resale
of Exchange Notes. The Letter of Transmittal states that by making such
acknowledgment a Participating Dealer will not be deemed to admit that it is
an "underwriter" within the meaning of the Securities Act.
 
  Based on interpretations by the Staff of the Commission set forth in no-
action letters issued to third parties, the Company believes that this
Prospectus, as it may be amended or supplemented from time to time, may, if
permitted by the Company, be used by Participating Broker-Dealers in order to
satisfy the prospectus delivery requirements applicable to Participating
Broker-Dealers in connection with the resale of Exchange Notes as described
above. The Company has agreed in the Registration Rights Agreement that it
will use its best efforts to make this Prospectus available to each
Participating Broker-Dealer for use in connection with any resales of such
Exchange Notes (subject to the right of the Company to restrict the use of
this Prospectus under certain circumstances specified in the Registration
Rights Agreement). The obligation of the Company to make this Prospectus
available as aforesaid will commence on the day that the Exchange Offer is
consummated and continue in effect for a 30-day period (the "Broker Prospectus
Period"); provided, however, that, if for any day during such period the
Company restricts the use of such prospectus, the Broker Prospectus Period
shall be extended on a day-for-day basis. See "Description of Registration
Rights Agreement."
 
  Any sale of Exchange Notes by Participating Broker-Dealers will be for their
own account, and the Company will not receive any proceeds of such sales.
 
  Participating Broker-Dealers may from time to time sell Exchange Notes that
were received by them in the Exchange Offer in one or more transactions in the
over-the-counter market, in privately negotiated transactions, through the
writing of options on the Exchange Notes or otherwise, and such sales may be
made at the market price prevailing at the time of sale, a price related to
such prevailing market price or a negotiated price. Such sales of Exchange
Notes may be made directly to purchasers or, alternatively, may be offered
from time to time through agents, brokers, dealers or underwriters, who may
receive compensation in the form of concessions or commissions from the
Participating Broker-Dealers or purchasers of the Exchange Notes (which
compensation may be in excess of customary commissions). Any agents, brokers
or dealers that participate in the distribution of the Exchange Notes may be
deemed to be underwriters and any commissions received by them and any profit
on the resale of such Exchange Notes sold by them might be deemed to be
underwriting discounts and commissions under the Securities Act.
 
  During the Broker Prospectus Period, the Company will promptly send
additional copies of this Prospectus and any amendment or supplement to this
Prospectus to any Participating Broker-Dealer that requests such documents
(subject to the right of the Company to restrict the use of this Prospectus
under certain circumstances specified in the Registration Rights Agreement).
Any such requests should be directed to United Rentals (North America), Inc.,
Attention: Corporate Secretary, Four Greenwich Office Park, Greenwich,
Connecticut 06830, telephone: (203) 622-3131.
 
  The Company has agreed in the Registration Rights Agreement to indemnify
each Participating Broker-Dealer that resells Exchange Notes pursuant to this
Prospectus, and their officers, directors and controlling persons, against
certain liabilities in connection with the offer and sale of the Exchange
Notes, including liabilities under the Securities Act, or to contribute to
payments that such Participating Broker-Dealers may be required to make in
respect thereof.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
 
  The following is a general discussion of certain United States federal
income and estate tax consequences of the acquisition, ownership and
disposition of Notes. This discussion is a summary for general information
purposes only and does not consider all aspects of federal income taxation
that may be relevant to a particular investor in light of his or her personal
circumstances. This discussion is generally limited to the tax consequences to
initial holders of the Notes that hold the Notes as capital assets (within the
meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the
"Code")) and that purchase the Notes at the "issue price." For this purpose,
the "issue price" of a Note is the first price at which a substantial part of
the Notes are sold to the public for money (excluding sales to bond houses,
brokers, or similar persons or organizations acting in the capacity of
underwriters, placement agents or wholesalers).
 
  This discussion is based upon the United States federal income tax laws now
in effect, which are subject to change, possibly retroactively. This
discussion generally does not describe the treatment of investors in pass-
through entities that hold the Notes. In addition, certain other holders
(including insurance companies, tax exempt organizations, financial
institutions and broker-dealers, persons who hold the Notes as part of a
"straddle," "hedge," or "conversion transaction" or other integrated
transaction, or persons that have a "functional currency" other than the U.S.
dollar) may be subject to special rules not discussed below.
 
  PROSPECTIVE INVESTORS ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING THE
UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF ACQUIRING, HOLDING AND
DISPOSING OF NOTES, AS WELL AS ANY TAX CONSEQUENCES THAT MAY ARISE UNDER THE
LAWS OF ANY FOREIGN, STATE, LOCAL OR OTHER TAXING JURISDICTION.
 
U.S. HOLDERS
 
  The following discussion is limited to the U.S. federal income tax
consequences to a "U.S. Holder" of a Note. For purposes of this discussion, a
"U.S. Holder" means a holder that is (i) an individual who is a citizen or a
resident of the United States; (ii) a corporation created or organized in the
United States or under the laws of the United States or of any political
subdivision thereof; (iii) an estate whose income is includable in gross
income for United States federal income tax purposes regardless of its source
or (iv) a trust, if a U.S. court is able to exercise primary supervision over
the administration of the trust and one or more United States persons have the
authority to control all substantial decisions of the trust.
 
 Stated Interest
 
  Stated interest on a Note will be taxable to a U.S. Holder as ordinary
income either at the time it accrues or is received in accordance with such
U.S. Holder's method of accounting. If the Company fails to comply with
certain provisions requiring registration of the Notes, the interest rate may
increase. Assuming that the contingency that the Company will pay such
additional interest is remote or incidental (within the meaning of applicable
Treasury regulations) such additional interest should be taxable to U.S.
Holders at the time it accrues or is received in accordance with each such
U.S. Holder's method of accounting.
 
 Redemption
 
  In the event of a Change of Control, the U.S. Holders of Notes will have the
right to require the Company to purchase their Notes. The Treasury regulations
provide that the right of U.S. Holders of the Notes to require redemption of
the Notes upon the occurrence of a Change of Control will not affect the yield
or maturity date of the Notes unless, based on all the facts and circumstances
as of the Issue Date, it is more likely than not that a Change of Control
giving rise to the redemption right will occur. The Company does not intend to
treat this redemption provision of the Notes as affecting the computation of
the yield to maturity of the Notes.
 
  The Company may redeem the Notes at any time on or after a certain date,
and, in certain circumstances, may redeem or repurchase all or a portion of
the Notes at any time prior to the maturity date. Under the Treasury
regulations, the Company will be deemed to exercise any option to redeem the
Notes if the exercise of such
 
                                      65
<PAGE>
 
option would lower the yield of the debt instrument. The Company believes, and
intends to take the position for all income tax purposes, that it will not be
treated as having exercised the option to redeem the Notes under these rules.
 
 Sale, Exchange, or Repayment of the Notes
 
  Upon the disposition of a Note by sale, exchange redemption or repayment,
the U.S. Holder will recognize gain or loss equal to the difference between
(i) the amount realized on the disposition (other than amounts attributable to
accrued interest not yet taken into income) and (ii) the U.S. Holder's tax
basis in the Note. A U.S. Holder's tax basis in the Note generally will equal
the cost of the Note.
 
  Because the Note is held as a capital asset, such gain or loss will
generally be capital gain or loss and will be long-term capital gain if the
Note is held for longer than one year. U.S. Holders are advised to consult
their tax advisors concerning these provisions on the taxation of capital
gains.
 
 Backup Withholding
 
  A U.S. Holder may be subject to backup withholding at a rate of 31% with
respect to interest, principal payments on the Notes, and proceeds from the
disposition of Notes unless the U.S. Holder (i) is a corporation or comes
within certain other exempt categories of recipients and, when required,
demonstrates that status, or (ii) provides a correct taxpayer identification
number, certifies as to no loss of exemption from backup withholding and
otherwise complies with the applicable requirements of the backup withholding
rules. U.S. Holders should consult their tax advisors as to their
qualification for exemption from backup withholding and the procedure for
obtaining such exemption.
 
  Backup withholding is not an additional tax. Any amount withheld as backup
withholding would be refunded or credited against the U.S. Holder's federal
income tax liability, provided that the required information is provided to
the Internal Revenue Service (the "IRS").
 
NON-U. S. HOLDERS
 
  The following discussion is limited to the U.S. federal income and estate
tax consequences to a holder of a Note that is a person other than a United
States person (a "Non-United States Holder"). For purposes of the withholding
tax on interest, a non-resident alien or other non-resident fiduciary of an
estate or trust will be considered to be a Non-United States Holder.
 
  For purposes of the discussion below, interest and gain on the sale,
exchange or other disposition of Notes will be considered to be "U.S. trade or
business income" if such income or gain is (i) effectively connected with the
conduct of a U.S. trade or business or (ii) in the case of a treaty resident,
attributable to a U.S. permanent establishment (or, in the case of an
individual, a fixed base) in the United States.
 
 Interest
 
  Interest paid by the Company to a Non-United States Holder will not be
subject to United States federal income or withholding tax if such interest is
not U.S. trade or business income and is "portfolio interest." Interest will
be portfolio interest if the Non-United States Holder (i) does not actually or
constructively own 10% or more of the total combined voting power of all
classes of stock of the Company entitled to vote; (ii) is not a controlled
foreign corporation with respect to which the Company is a "related person"
within the meaning of the Code and (iii) certifies, under penalties of
perjury, that such holder is not a United States person and provides such
holder's name and address.
 
  The gross amount of payments of interest that do not qualify for the
portfolio interest exception and that are not U.S. trade or business income
will be subject to U.S. withholding tax at a rate of 30% unless a treaty
applies
 
                                      66
<PAGE>
 
to reduce or eliminate withholding. U.S. trade or business income will be
taxed at regular, graduated U.S. rates rather than the 30% gross rate. In the
case of a Non-United States Holder that is a corporation, such U.S. trade or
business income may also be subject to the branch profits tax equal to 30% (or
such lower treaty rate as may be applicable) of its "effectively connected
earnings and profits." To claim exemption from withholding or to claim the
benefits of a treaty, a Non-United States Holder must provide a properly
executed Form 1001 or 4224 (or such successor form as the IRS designates), as
applicable prior to the payment of interest. These forms must be periodically
updated. Under regulations not yet in effect, the Forms 1001 and 4224 will be
replaced by a Form W-8. Also under these regulations, a Non-United States
Holder who is claiming the benefits of a treaty may be required in certain
instances to obtain a U.S. taxpayer identification number and to provide
certain documentary evidence issued by foreign governmental authorities to
prove residence in the foreign country.
 
 Gain on Disposition
 
  A Non-United States Holder will generally not be subject to United States
federal income tax on gain recognized on a sale, redemption or other
disposition of a Note unless (i) the gain is effectively connected with the
conduct of a trade or business within the United States by the Non-United
States Holder; (ii) in the case of a Non-United States Holder who is a
nonresident alien individual and holds the Note as a capital asset, such
holder is present in the United States for 183 or more days in the taxable
year and certain other requirements are met; or (iii) the Non-United States
Holder is subject to the special rules applicable to certain former citizens
and residents of the United States.
 
 Federal Estate Taxes
 
  If the interest on the Notes is exempt from withholding of United States
federal income tax as portfolio interest described above, the Notes will not
be included in the estate of a deceased Non-United States Holder for United
States federal estate tax purposes.
 
 Information Reporting and Backup Withholding
 
  The Company must report annually to the IRS and to each Non-United States
Holder any interest paid to the Non-United States Holder. Copies of these
information returns may also be made available under the provisions of a
specific treaty or other agreement to the tax authorities of the country in
which the Non-United States Holder resides.
 
  In the case of payments of interest to Non-United States Holders, Treasury
regulations provide that the 31% backup withholding tax and certain
information reporting will not apply to such payments with respect to which
either the requisite certification, as described above, has been received or
an exemption has otherwise been established; provided that neither the Company
nor its payment agent has actual knowledge that the holder is a United States
person or that the conditions of any other exemption are not in fact
satisfied. The payment of the proceeds from the disposition of Notes to or
through the United States office of any broker, U.S. or foreign, will be
subject to information reporting and possible backup withholding unless the
owner certifies as to its non-U.S. status under penalty of perjury or
otherwise establishes an exemption, provided that the broker does not have
actual knowledge that the Holder is a United States person or that the
conditions of any other exemption are not, in fact, satisfied. The payment of
the proceeds from the disposition of Notes to or through a non-U.S. office of
a non-U.S. broker will not be subject to information reporting or backup
withholding unless the non-U.S. broker has certain types of relationships with
the United States (a "United States Related Person").
 
  In the case of the payment of proceeds from the disposition of Notes to or
through a non-United States office of a broker that is either a United States
person or a United States Related Person, the regulations require information
reporting on the payment unless the broker has documentary evidence in its
files that the owner is a Non-United States Holder and the broker has no
knowledge to the contrary. Backup withholding will not apply to payments made
through foreign offices of a broker that is not a United States person nor a
United States Related Person (absent actual knowledge that the payee is a
United States person).
 
                                      67
<PAGE>
 
  The Treasury Department recently promulgated final regulations (the "Final
Regulations") regarding the withholding and information reporting rules
discussed above. In general, the Final Regulations do not significantly alter
the substantive withholding and information reporting requirements but rather
unify current certification procedures and forms and clarify reliance
standards. The Final Regulations are generally effective for payments made
after December 31, 1999, subject to certain transition rules. Non-United
States Holders should consult their own tax advisors with respect to the
impact, if any, of the new Final Regulations.
 
  Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules may be refunded or credited against the Non-United
States Holder's United States federal income tax liability, provided that the
required information is furnished to the IRS.

                         CERTAIN ERISA CONSIDERATIONS
 
  Each purchaser of Notes will be deemed to have agreed that it shall not sell
or otherwise transfer such Notes to, and each purchaser represents and
covenants that it is not acquiring the Notes for or on behalf of, and will not
transfer the Notes to, any pension or welfare plan (as defined in Section 3 of
the Employee Retirement Income Security Act of 1974, as amended ("ERISA")) or
plan (as defined in Section 4975 of the Internal Revenue Code of 1986, as
amended ("Code") (collectively, a Plan)), except that such a purchase for or

  and which is subject to supervision and examination by a state authority
  having supervision over insurance companies, or (D) a savings and loan
  association, the accounts of which are insured by the Federal Deposit
  Insurance Corporation, that has made application for and been granted trust
  powers to manage, acquire or dispose of assets of a Plan by a State or
  Federal authority having supervision over savings and loan associations,
  which savings and loan association has, as of the last day of its most
  recent fiscal year, equity capital or net worth in excess of $1,000,000
  and, in any case, such investment adviser, bank, insurance company or

  the Department of Labor, with respect to such Plan, and the assets of such
  Plan managed by such investment advisor, bank, insurance Company or savings
  and loan, when combined with the assets of other Plans established or
  maintained by the same employer (or affiliate thereof, as defined in such
  exemption) or employee organization and managed by such investment adviser,

                  PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
  The following pro forma unaudited consolidated balance sheet of the Company
gives effect to  the acquisitions completed by the Company subsequent to
September 30, 1998 (through February 11, 1999) and the financing thereof, as
if all such transactions had occurred on September 30, 1998.
 
  The following pro forma unaudited consolidated statement of operations with
respect to the nine months ended September 30, 1998 and the year ended
December 31, 1997, give effect to each acquisition completed by the Company
after the beginning of the period (through February 11, 1999) and the
financing thereof and as if all such transactions had occurred at the
beginning of the period.

1. BASIS OF PRESENTATION
 
  The Company is a large geographically diversified equipment rental company
in the United States, Canada and Mexico. The Company rents a broad array of
equipment to a diverse customer base that includes construction industry
participants, industrial companies, homeowners and other individuals. The
Company also sells rental equipment, acts as a distributor for certain new
equipment, and sells related merchandise and parts.
 
  The financial data for United Rentals (North America), Inc. is derived from
the historical financial statements of the Company. The financial data for
each of the acquisitions is derived from the respective historical financial
statements of such companies. The results of operations for each acquisition
acquired during a period presented includes the results of operations from the
beginning of such period through the date of acquisition.
 
2. ACQUISITIONS
 
  Since its formation, the Company has completed a total of 97 acquisitions
through February 11, 1999. These include the acquisition of the six companies
in October 1997 and the acquisition of 91 additional companies thereafter.
 
  Based upon management's preliminary estimates, it is estimated that the
carrying value of the assets and liabilities of the 22 companies acquired by
the Company subsequent to September 30, 1998 approximates fair value, with the
exception of rental equipment and other property and equipment, which required
adjustments to reflect fair market value. The following table presents the
allocation of purchase price of each of the 22 companies acquired by the
Company subsequent to September 30, 1998:

ITEM 20. 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 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 Registrant, 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 Registrant. 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
certain of 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 Registrant has purchased
insurance on behalf of its present and former directors and officers against
any liability asserted against or incurred by them in such capacity or arising
out of their status as such. The Registrant has entered into indemnification
agreements with certain members of its management in the form filed as an
exhibit to this registration statement.

ITEM 22. UNDERTAKINGS
 
  A. The 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. Notwithstanding the foregoing, any increase or
  decrease in volume of securities offered (if the total dollar value of
  securities offered would not exceed that which was registered) and any
  deviation from the low or high end of the estimated maximum offering range
  may be reflected in the form of prospectus filed with the Commission
  pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
  price represent no more than a 20% change in the maximum aggregate offering
  price set forth in the "Calculation of Registration Fee" table in the
  effective 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 registration statement is on Form S-3, Form S-8 or F-3, and 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 Section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in this Registration Statement.
 
  (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. (1) The undersigned registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of
a prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145, the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.
 
 
                                     II-2
<PAGE>
 
  (2) The registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used
in connection with an offering of securities subject to Rule 415, will be
filed as a part of an amendment to the registration statement and will not be
used until such amendment is effective, and that, for purposes 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.
 
  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 provisions described under Item 20 above, 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 expense 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 against the registrant 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.
 
  D. The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through
the date of responding to the request.
 
  E. The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
