annum equal to the sum of the Eurodollar Rate applicable to each Interest Period
for such Tranche plus 2.25%;

provided, however, that at any time an Event of Default exists, the interest
--------  -------
rate applicable to each Tranche shall be increased by 2%.

B.   Interest Payment Dates.  Accrued interest on each Base Rate Tranche shall
     ----------------------
be payable in arrears on the last day of each calendar month and at maturity.
Accrued interest on each Eurodollar Tranche shall be payable on the last day of
each Interest Period for such Tranche (and, in the case of a Eurodollar Tranche

day of such Interest Period) and at maturity. After maturity, accrued
<PAGE>

interest on all Tranches shall be payable on demand.

C.   Setting and Notice of Certain Rates.  The applicable Eurodollar Rate for
     -----------------------------------
each Interest Period shall be determined by the Agent, and notice thereof shall
be given by the Agent promptly to the Company and the Lenders. Each
determination of the applicable Eurodollar Rate by the Agent shall be conclusive
and binding upon the parties hereto, in the absence of demonstrable error. The
Agent shall, upon written request of the Company or any Lender, deliver to the
Company or such Lender a statement showing the computations used by the Agent in

D.   Computation of Interest.
     -----------------------

a.             All computations of interest on Base Rate Tranches when the Base
Rate is determined by the Reference Rate shall be made on the basis of a year of
365 or 366 days, as the case may be, and actual days elapsed. All other
computations of interest shall be made on the basis of a 360-day year and actual
days elapsed (which results in more interest being paid than if computed on the
basis of a 365-day year). Interest shall accrue during each period during which
interest is computed from the first day thereof to the last day thereof.

b.             If for any reason whatsoever a Reference Lender ceases to be a
Lender hereunder, such Reference Lender shall thereupon cease to be a Reference
Lender, and the Eurodollar Rate shall be determined on the basis of the rates as
notified by the remaining Reference Lender(s).

c.             Each of the Reference Lenders shall use its best efforts to
furnish quotations of rates to the Agent as contemplated hereby. If any
Reference Lender fails to supply such rates to the Agent upon its request, the
Eurodollar Rate shall be determined on the basis of the quotations of the
remaining Reference Lender(s).

d.             Anything herein to the contrary notwithstanding, the obligations
of the Company to any Lender hereunder shall be subject to the limitation that
payments of interest shall not be required for any period for which interest is
computed hereunder to the extent (but only to the extent) that contracting for
or receiving such payment by such Lender would be contrary to the provisions of
any law applicable to such Lender limiting the highest rate of interest that may
be lawfully contracted for, charged or received by such Lender, and in such
event the Company shall pay such Lender interest at the highest rate permitted
by applicable law.

e.             The applicable interest rate for each Base Rate Tranche shall
change simultaneously with each change in the Base Rate.

V.   SECTION FEES.

     5.1  Fees.  On the Effective Date, the Company shall pay to the Agent for

each Lender) notice of any prepayment not later than 10:00 A.M., Chicago time,
on the day of such prepayment, specifying the Tranches to be prepaid and the
date and amount of prepayment. Each partial prepayment of Loans shall be in a
principal amount of at least U.S.$500,000. Any prepayment of a Eurodollar
Tranche on a day other than the last day of an Interest Period therefor shall be
subject to Section 8.4. All prepayments shall be applied pro rata to the then-
           -----------
remaining installments of the Notes.

A.   Making of Payments.  (a)  All payments of principal of or interest on the
     ------------------
Notes shall be made by the Company to the Agent in immediately available funds
at the office specified by the Agent not later than noon, Chicago time, on the
date due; and funds received after that hour shall be deemed to have been
received by the Agent on the next following Business Day. The Company hereby
authorizes and instructs the Agent to charge any demand deposit account of the
Company maintained with BofA for the amount of any such payment on the due date
therefor, and (subject to there being a sufficient balance in such account for
such purpose) the Agent agrees to do so, provided that the Agent's failure to so
                                         --------
charge any such account shall in no way affect the obligation of the Company to
make any such payment.  The Agent shall promptly remit to each Lender its share
of all such payments received in collected funds by the Agent for the account of
such Lender.

          (b)  All payments under Section 8.1 shall be made by the Company
                                  -----------
directly to the Lender entitled thereto.

          (c)  Unless the Agent receives notice from the Company prior to the
date on which any payment is due to the Lenders that the Company will not make
such payment in full as and when required, the Agent may assume that the Company
has made such payment in full to the Agent on such date in immediately available
funds and the Agent may (but shall not be so required), in reliance upon such
assumption, distribute to each Lender on such due date an amount equal to the
amount then due such Lender.  If and to the extent the Company has not made such
payment in full to the Agent, each Lender shall repay to the Agent on demand the
amount distributed to such Lender, together with interest thereon at the Federal
Funds Rate for each day from the date such amount is distributed to such Lender
until the date repaid.

B.   Due Date Extension.  If any payment of principal or interest with respect
     ------------------
to any of the Loans falls due on a day which is not a Business Day, then such
due date shall be extended to the immediately following Business Day (unless, in
the case of a Eurodollar Tranche, such immediately following Business Day is the
first Business Day of a calendar month, in which case such date shall be the
immediately preceding Business Day) and, in the case of principal,
<PAGE>

additional interest shall accrue and be payable for the period of any such
extension.

C.   Setoff.  The Company agrees that the Agent and each Lender have all rights
     ------
of set-off and bankers' lien provided by applicable law, and in addition

or (b) any Unmatured Event of Default under Section 12.1.4 with respect to the
                                            --------------
Company or any Event of Default exists, the Agent and each Lender may apply to
the payment of such payment or other amount (or, in the case of clause (b), to
                                                                ----------
any obligations of the Company hereunder, whether or not then due) any and all
balances, credits, deposits, accounts or moneys of the Company then or
thereafter with the Agent or such Lender.

D.   Proration of Payments.  If any Lender shall obtain any payment or other
     ---------------------
recovery (whether voluntary, involuntary, by application of offset or otherwise,
but excluding any payment pursuant to Section 8.7 or 14.9) on account of
                                      -----------    ----
principal of or interest on any Note in excess of its pro rata share of payments
and other recoveries obtained by all Lenders on account of principal of and
interest on the applicable Notes then held by them, such Lender shall purchase
from the other Lenders such participation in the applicable Notes held by them
as shall be necessary to cause such purchasing Lender to share the excess
payment or other recovery ratably with each of them; provided, however, that if
                                                     --------  -------
all or any portion of the excess payment or other recovery is thereafter
recovered from such purchasing Lender, the purchase shall be rescinded and the
purchase price restored to the extent of such recovery (but without interest).

E.   Taxes.  (a) All payments of principal of, and interest on, the Loans and
     -----
all other amounts payable hereunder shall be made free and clear of and without
deduction for any present or future income, excise, stamp or franchise taxes and
other taxes, fees, duties, withholdings or other charges of any nature
whatsoever imposed by any taxing authority, but excluding franchise taxes and
taxes imposed on or measured by any Lender's net income or receipts (all non-
excluded items being called "Taxes"). If any withholding or deduction from any
                             -----
payment to be made by the Company hereunder (including any additional amount or
amounts to be paid under this Section 7.5) is required in respect of any Taxes
                              -----------
pursuant to any applicable law, rule or regulation, then the Company will:

     (i)   pay directly to the relevant authority the full amount required to be
so withheld or deducted;

     (ii)  promptly forward to the Agent an official receipt or other
documentation satisfactory to the Agent evidencing such payment to such
authority; and

     (iii) pay to the Agent for the account of the Lenders such additional
amount or amounts as is necessary to ensure that the net amount actually
received by each Lender will equal the full amount such Lender would have
received had no such withholding or deduction been required.

Moreover, if any Taxes are directly asserted against the Agent or any Lender
with respect to any payment received by the Agent or such Lender hereunder, the
Agent or such Lender may pay such Taxes and the Company will promptly pay such
additional amounts (including any penalty, interest and expense) as is necessary
in order that the net amount received by such Person after

the payment of such Taxes (including any Taxes on such additional amount) shall
equal the amount such Person would have received had such Taxes not been
asserted.

     (b)  If the Company fails to pay any Taxes when due to the appropriate
taxing authority or fails to remit to the Agent, for the account of the
applicable Lender, the required receipts or other required documentary evidence,
the Company shall indemnify such Lender for any incremental Taxes, interest or
penalties that may become payable by any such Lender as a result of any such
failure.  For purposes of this Section 7.5, a distribution hereunder by the
                               -----------
Agent to or for the account of any Lender shall be deemed a payment by the
Company.

     (c)  Upon the request from time to time of the Company or the Agent, each
Lender that is organized under the laws of a jurisdiction other than the United
States of America or any state thereof shall execute and deliver to the Company
and the Agent one or more (as the Company or the Agent may reasonably request)
United States Internal Revenue Service Forms 4224 or Forms 1001 or any
applicable successor form (including Form W-8ECI or W-8BEN) or such other forms
or documents, appropriately completed, as may be applicable to establish the
extent, if any, to which a payment by the Company to such Lender is exempt from
withholding or deduction of Taxes.

     (e)  The obligations of the Company under this Section 7.5 (i) are subject
                                                    -----------
to the limitations set out in Section 14.9.1 and (ii) shall survive repayment of
                              --------------
the Loans, cancellation of the Notes and any termination of this Agreement.

VIII.  SECTION INCREASED COSTS; SPECIAL PROVISIONS FOR EURODOLLAR TRANCHES.

A.   Increased Costs.
     ---------------

a.           If, after the date hereof, the adoption of or any change in any
applicable law, rule or regulation, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by any Lender (or any Eurodollar Office of such Lender) with any request or
directive (whether or not having the force of law) of any such authority,
central bank or comparable agency

(a)          shall subject any Lender (or any Eurodollar Office of such Lender)
to any tax, duty or other charge with respect to its Eurodollar Tranches, its
Note or its obligation to maintain Eurodollar Tranches, or shall change the
basis of taxation of payments to any Lender of the principal of or interest on
its Eurodollar Tranches or any other amounts due under this Agreement in respect
of its Eurodollar Tranches or its obligation to maintain Eurodollar Tranches
(except for changes in the rate of tax on the overall net income of such Lender
or its Eurodollar Office imposed by the jurisdiction in which such Lender's
principal executive office or Eurodollar Office is located); or

(b)          shall impose, modify or deem applicable any reserve (including any
reserve
<PAGE>

imposed by the FRB, but excluding any reserve included in the determination of
interest rates pursuant to Section 4), special deposit or similar requirement
                           ---------
against assets of, deposits with or for the account of, or credit extended by
any Lender (or any Eurodollar Office of such Lender); or

(c)          shall impose on any Lender (or its Eurodollar Office) any other
condition affecting its Eurodollar Tranches, its Note or its obligation to
maintain Eurodollar Tranches;

and the result of any of the foregoing is to increase the cost to (or, in the
case of Regulation D of the FRB, to impose a cost on) such Lender (or any
Eurodollar Office of such Lender) of making, maintaining or participating in any
Eurodollar Tranche, or to reduce the amount of any sum received or receivable by
such Lender (or its Eurodollar Office) under this Agreement or under its Note
with respect thereto, then within 10 days after demand by such Lender (which
demand shall be accompanied by a statement setting forth the basis for such
demand, a copy of which shall be furnished to the Agent), the Company shall pay
directly to such Lender such additional amount as will compensate such Lender
for such increased cost or such reduction.

b.           If any Lender shall reasonably determine that the adoption or
phase-in of or any change in any applicable law, rule or regulation regarding
capital adequacy, or any change in the interpretation or administration thereof
by any governmental authority, central bank or comparable agency charged with
the interpretation or administration thereof, or compliance by any Lender or any
Person controlling such Lender with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate of
return on such Lender's or such controlling Person's capital as a consequence of
such Lender's obligations hereunder to a level below that which such Lender or
such controlling Person could have achieved but for such adoption, change or
compliance (taking into consideration such Lender's or such controlling Person's
policies with respect to capital adequacy) by an amount deemed by such Lender or
such controlling Person to be material, then from time to time, within 10 days
after demand by such Lender (which demand shall be accompanied by a statement
setting forth the basis for such demand, a copy of which shall be furnished to
the Agent), the Company shall pay to such Lender such additional amount or
amounts as will compensate such Lender or such controlling Person for such
reduction.

B.   Basis for Determining Interest Rate Inadequate or Unfair.  If with respect
     --------------------------------------------------------
to any Interest Period:

a.           none of the Reference Lenders are being offered deposits in U.S.
Dollars (in the applicable amounts) in the interbank Eurodollar market for such
Interest Period, or the Agent otherwise reasonably determines (which
determination shall be binding and conclusive on the Company) that by reason of
circumstances affecting the interbank Eurodollar market adequate and reasonable
means do not exist for ascertaining the Eurodollar Rate; or

b.           Lenders having an aggregate Percentage of 30% or more advise the
Agent that
<PAGE>

the Eurodollar Rate, as determined by the Agent, will not adequately and fairly
reflect the cost to such Lenders of maintaining or funding their Eurodollar
Tranches for such Interest Period (taking into account any amount to which such
Lenders may be entitled under Section 8.1) or that the maintaining or funding of
                              -----------
Eurodollar Tranches has become impracticable as a result of an event occurring
after the date of this Agreement which in the opinion of such Lenders materially
affects such Tranches;

then the Agent shall promptly notify the Company and the Lenders thereof and, so
----
long as such circumstances shall continue, (i) no Lender shall be under any
obligation to convert into Eurodollar Tranches and (ii) on the last day of the
current Interest Period for each Eurodollar Tranche, such Tranche shall, unless
then repaid in full, automatically convert to a Base Rate Tranche.

C.   Changes in Law Rendering Eurodollar Lending Unlawful. If any change in
     ----------------------------------------------------
(including the adoption of any new) applicable laws or regulations, or any
change in the interpretation of applicable laws or regulations by any
governmental or other regulatory body charged with the administration thereof,
should make it (or in the good faith judgment of any Lender cause a substantial
question as to whether it is) unlawful for any Lender to make, maintain or fund
any Eurodollar Tranche, then such Lender shall promptly notify the Company and
the Agent and, so long as such circumstances shall continue, (a) such Lender
shall have no obligation to make or convert into Eurodollar Tranches (but shall
make or maintain Base Rate Tranches concurrently with the making of or
conversion into Eurodollar Tranches by the Lenders which are not so affected, in
each case in an amount equal to such Lender's pro rata share of all Eurodollar
Tranches which would be made or converted into at such time in the absence of
such circumstances) and (b) on the last day of the current Interest Period for
each Eurodollar Tranche of such Lender (or, in any event, on such earlier date
as may be required by the relevant law, regulation or interpretation), such
Eurodollar Tranche shall, unless then repaid in full, automatically convert to a
Base Rate Tranche. Each Base Rate Tranche maintained by a Lender which, but for
the circumstances described in the foregoing sentence, would be a Eurodollar
Tranche (an "Affected Tranche") shall remain outstanding for the same period as
             ----------------
the Group of Eurodollar Tranches of which such Affected Tranche would be a part
absent such circumstances.

D.   Funding Losses.  The Company hereby agrees that upon demand by any Lender
     --------------
(which demand shall be accompanied by a statement setting forth the basis for
the amount being claimed, a copy of which shall be furnished to the Agent), the
Company will indemnify such Lender against any net loss or expense which such
Lender may sustain or incur (including any net loss or expense incurred by
reason of the liquidation or reemployment of deposits or other funds acquired by
such Lender to fund or maintain any Eurodollar Tranche), as reasonably
determined by such Lender, as a result of (a) any payment, prepayment or
conversion of any Eurodollar Tranche of such Lender on a date other than the
last day of an Interest Period for such Tranche (including any conversion
pursuant to Section 8.3) or (b) any failure of the Company to borrow, convert
            -----------
into, continue or prepay any Eurodollar Tranche on a date specified therefor in
a notice of borrowing, conversion, continuation or prepayment pursuant to this
Agreement.  For this purpose, all notices to the Agent pursuant to this
Agreement shall be deemed to be
<PAGE>

irrevocable.

E.   Right of Lenders to Fund through Other Offices. Each Lender may, if it so
     ----------------------------------------------
elects, fulfill its commitment as to any Eurodollar Tranche by causing a foreign
branch or affiliate of such Lender to maintain or fund such Tranche, provided
                                                                     --------
that in such event for the purposes of this Agreement such Tranche shall be
deemed to have been maintained and funded by such Lender and the obligation of
the Company to repay such Lender's Loan shall nevertheless be to such Lender and
shall be deemed held by it, to the extent of such Loan, for the account of such
branch or affiliate.

F.   Discretion of Lenders as to Manner of Funding.  Notwithstanding any
     ---------------------------------------------
provision of this Agreement to the contrary, each Lender shall be entitled to
fund and maintain its funding of all or any part of its Loan in any manner it
sees fit, it being understood, however, that for the purposes of this Agreement
all determinations hereunder shall be made as if such Lender had actually funded
and maintained each Eurodollar Tranche during each Interest Period for such
Tranche through the purchase of deposits having a maturity corresponding to such
Interest Period and bearing an interest rate equal to the IBOR (as defined in
the definition of Eurodollar Rate) for such Interest Period.

G.   Mitigation of Circumstances; Replacement of Affected Lender.
     -----------------------------------------------------------

a.           Each Lender shall promptly notify the Company and the Agent of
any event of which it has knowledge which will result in, and will use
reasonable commercial efforts available to it (and not, in such Lender's good
faith judgment, otherwise disadvantageous to such Lender) to mitigate or avoid,
(i) any obligation of the Company to pay any amount pursuant to Section 7.5 or
                                                                -----------
8.1 or (ii) the occurrence of any circumstances of the nature described in
---
Section 8.2 or 8.3, and, if any Lender has given notice of any event described
-----------    ---
in clause (i) or (ii) above and thereafter such event ceases to exist, such
   ----------    ----
Lender shall promptly so notify the Company and the Agent.  Without limiting the
foregoing, each Lender will designate a different funding office if such
designation will avoid (or reduce the cost to the Company of) any event
described in clause (i) or (ii) of the preceding sentence and such designation
             ----------    ----
will not, in such Lender's sole judgment, be otherwise disadvantageous to such
Lender.

b.           At any time any Lender is an Affected Lender, the Company may
replace such Affected Lender as a party to this Agreement with one or more other
bank(s) or financial institution(s) reasonably satisfactory to the Agent (and
upon notice from the Company such Affected Lender shall assign pursuant to an
Assignment Agreement, and without recourse or warranty, its Loan, its Note and
all of its other rights and obligations hereunder to such replacement bank(s) or
other financial institution(s) for a purchase price equal to the sum of the
principal amount of the Loan so assigned, all accrued and unpaid interest
thereon, any amounts payable under Section 8.4 as a result of such Lender
                                   -----------
receiving payment of any Eurodollar Tranche prior to the end of an Interest
Period therefor and all other obligations owed to such Affected Lender
hereunder).

H.   Conclusiveness of Statements; Survival of Provisions. Determinations and
     ----------------------------------------------------
statements of any Lender pursuant to Section 8.1, 8.2, 8.3 or 8.4 shall be
                                     -----------  ---  ---    ---
conclusive absent demonstrable error. Lenders may use reasonable averaging and
attribution methods in determining
<PAGE>

compensation under Sections 8.1 and 8.4, and the provisions of such Sections
                   ------------     ---
shall survive repayment of the Loans, cancellation of the Notes and any
termination of this Agreement.

neither Parent nor any member of the Controlled Group has received any notice
that any Multiemployer Pension Plan is in reorganization, that increased
contributions may be required to avoid a reduction in plan benefits or the
imposition of any excise tax, that any Multiemployer Pension Plan is or has been
funded at a rate less than that required under Section 412 of the Code, that any

     ----------------------
"investment company" or a company "controlled" by an "investment company",

company", within the meaning of the Public Utility Holding Company Act of 1935.

L.   Regulation U.  The Company is not engaged principally, or as one of its
     ------------
important activities, in the business of purchasing or carrying Margin Stock or

which are being diligently contested in good faith by appropriate proceedings
and for which adequate reserves in accordance with GAAP shall have been set
aside on its books.

to pay its debts as they mature, will own property with fair saleable value
greater than the amount required to pay its debts and will have capital
sufficient to carry on its business as then constituted.

O.   Environmental Matters. Parent conducts in the ordinary course of business a
     ---------------------
review of the effect of existing Environmental Laws and existing Environmental
Claims on its business, operations and properties, and as a result thereof
Parent has reasonably concluded that, except as specifically disclosed in
Schedule 9.15, such Environmental Laws and Environmental Claims could not,
-------------
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.

P.   Year 2000 Problem.  Parent and its Subsidiaries have reviewed the areas
     -----------------
within their business and operations which could be adversely affected by, and
have developed or are developing a program to address on a timely basis, the
"Year 2000 Problem" (that is, the risk that computer applications used by Parent
and its Subsidiaries may be unable to recognize and perform properly date-
sensitive functions involving certain dates prior to and any date after December
31, 1999). Based on such review and program, Parent reasonably believes that the
"Year 2000 Problem" will not have a Material Adverse Effect.

     -----------
Indebtedness" as such term is defined in each Subordinated Note Indenture.

statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons,

Agent shall be fully justified in failing or refusing to take any action under
this Agreement or any other Loan Document unless it shall first receive such
advice or concurrence of the Required Lenders (or, if required, all Lenders) as
it deems appropriate and, if it so requests, confirmation from the Lenders of

Lender represents to the Agent that it has, independently and without reliance

has deemed appropriate, made its own appraisal of and investigation into the
business, prospects, operations, property, financial and other condition and

and all applicable bank regulatory laws relating to the transactions
contemplated hereby, and made its own decision to enter into this Agreement and

will, independently and without reliance upon any Agent-Related Person and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not taking action under this Agreement and the other Loan Documents, and to make
such investigations as it deems necessary to inform itself

condition and creditworthiness of the Company. Except for notices, reports and
other documents expressly herein required to be furnished to the Lenders by the
Agent, the Agent shall not have any duty or responsibility to provide any Lender

          ---------------
hereby are consummated, the Lenders shall indemnify upon demand the Agent-
Related Persons (to the extent not reimbursed by or on behalf of the Company and
without limiting the obligation of the Company to do so), pro rata, from and
against any and all Indemnified Liabilities; provided, however, that no Lender
                                             --------  -------

the Indemnified Liabilities resulting from such Person's gross negligence or

administration, modification, amendment or enforcement (whether through

rights or responsibilities under, this Agreement, any other Loan Document, or
any document contemplated by or referred to herein, to the extent that the Agent

Agent or the replacement of any Lender)  be imposed on, incurred by or asserted
against any Agent-Related Person in any way relating to or arising out of this

request of the Required Lenders shall, resign as Agent upon 30 days' notice to
the Lenders. If the Agent resigns under this Agreement, the Required Lenders
shall, with (so long as no Event of Default exists) the consent of the Company
(which shall not be unreasonably withheld or delayed), appoint from among the
Lenders a successor Agent for the Lenders. If no successor agent is appointed
prior to the effective date of the resignation of the Agent, the Agent may
appoint, after consulting with the Lenders and the Company, a successor agent
from among the Lenders. Upon the acceptance of its appointment as successor
agent hereunder, such successor agent shall succeed to all the rights, powers
and duties of the retiring Agent and the term "Agent" shall mean such successor
agent, and the retiring Agent's appointment, powers and duties as Agent shall be
terminated. After any retiring Agent's resignation hereunder as Agent, the
provisions of this Section 13 and Sections 14.6 and 14.13 shall inure to its
                   ----------     -------------     -----
benefit as to any actions taken or omitted to be taken by it while it was the
Agent under this Agreement.  If no successor agent has accepted appointment as
the Agent by the date which is 30 days following a retiring Agent's notice of
resignation, the retiring Agent's resignation shall nevertheless thereupon
become effective and the Lenders shall perform all of the duties of the Agent
hereunder until such time, if any, as the Required Lenders appoint a successor
agent as provided for above.

J.        Withholding Tax.
          ---------------

          (a)  If any Lender is a "foreign corporation, partnership or trust"
within the meaning of the Code and such Lender claims exemption from, or a
reduction of, U.S. withholding tax under Section 1441 or 1442 of the Code, such
Lender agrees to deliver to the Agent:

              (i)   if such Lender claims an exemption from, or a reduction of,
          withholding tax under a United States tax treaty, properly completed
          Internal Revenue Service ("IRS") Forms 1001 and W-8 or any applicable
                                     ---
          successor form before the payment of any interest in the first
          calendar year and before the payment of any interest in each third
          succeeding calendar year during which interest may be paid under this
          Agreement;

              (ii)  if such Lender claims that interest paid under this
          Agreement is


<PAGE>

     exempt from United States withholding tax because it is effectively
     connected with a United States trade or business of such Lender, two
     properly completed and executed copies of IRS Form 4224 or any applicable
     successor form (including Form W-8ECI) before the payment of any interest
     is due in the first taxable year of such Lender and in each succeeding
     taxable year of such Lender during which interest may be paid under this
     Agreement, and IRS Form W-9;

               (iii)  if such Lender is not a "bank" within the meaning of
     Section 881(c)(3)(A) of the Code and cannot deliver either IRS Form 1001 or
     4224 (including Form W-8BEN or Form W-8ECI) or any applicable successor
     form, (A) a certificate substantially in the form of Exhibit J and (B) two
                                                          ---------
     properly completed and signed copies of IRS Form W-8 certifying that such
     Lender is entitled to an exemption from United States withholding tax with
     respect to payments of interest to be made under this Agreement; and

          (iv)  such other form or forms as may be required under the Code or
     other laws of the United States as a condition to exemption from, or
     reduction of, United States withholding tax.

Any such Lender agrees to promptly notify the Agent of any change in
circumstances which would modify or render invalid any claimed exemption or
reduction.

     (b)  If any Lender claims exemption from, or reduction of, withholding tax
under a United States tax treaty by providing IRS Form 1001 or any applicable
successor form (including Form W-8BEN) and such Lender sells, assigns, grants a
participation in, or otherwise transfers all or part of the obligations of the
Company to such Lender, such Lender agrees to notify the Agent of the percentage
amount in which it is no longer the beneficial owner of such obligations of the
Company hereunder. To the extent of such percentage amount, the Agent will treat
such Lender's IRS Form 1001 (or any applicable successor form) as no longer
valid.

     (c)  If any Lender claiming exemption from United States withholding tax by
filing IRS Form 4224 or any applicable successor form (including Form W-8ECI)
with the Agent grants a participation in all or part of the obligations of the
Company to such Lender hereunder, such Lender agrees to undertake sole
responsibility for complying with the withholding tax requirements imposed by
Sections 1441 and 1442 of the Code.

     (d)  If any Lender is entitled to a reduction in the applicable withholding
tax, the Agent may withhold from any interest payment to such Lender an amount
equivalent to the applicable withholding tax after taking into account such
reduction. If the forms or other documentation required by subsection (a) of
                                                           --------------
this Section are not delivered to the Agent, then the Agent may withhold from
any interest payment to such Lender not providing such forms or other
documentation an amount equivalent to the applicable withholding tax.
<PAGE>

     (e)  If the IRS or any other governmental authority of the United States or
any other jurisdiction asserts a claim that the Agent did not properly withhold
tax from amounts paid to or for the account of any Lender (because such Lender
failed to notify the Agent of a change in circumstances which rendered an
exemption from, or reduction of, withholding tax ineffective), such Lender shall
indemnify the Agent fully for all amounts paid, directly or indirectly, by the
Agent as tax or otherwise, including penalties and interest, and including any
taxes imposed by any jurisdiction on any amount payable to the Agent under this
Section, together with all costs and expenses (including reasonable fees of
attorneys for the Agent (including the allocable costs of internal legal
services and all disbursements of internal counsel)). The obligations of the
Lenders under this subsection shall survive the repayment of the Loans,
cancellation of the Notes, any termination of this Agreement and the resignation
or replacement of the Agent.

     (f)  If any Lender claims exemption from, or reduction of, withholding tax
under the Code by providing IRS Form W-8 and a certificate in the form of
Exhibit J and such Lender sells, assigns, grants a participation in, or
---------
otherwise transfers all or part of the obligations of the Company to such
Lender, such Lender agrees to notify the Agent and the Company of the percentage
amount in which it is no longer the beneficial owner of obligations of the
Company to such Lender. To the extent of such percentage amount, the Agent and
the Company will treat such Lender's IRS Form W-8 and certificate in the form of
Exhibit J as no longer valid.
---------

K.   Documentation Agent.  No Lender identified on the facing page or the
     -------------------
signature pages of this Agreement as a "Documentation Agent" shall have any
right, power, obligation, liability, responsibility or duty under this Agreement
other than those applicable to all Lenders as such.  Without limiting the
foregoing, no Lender so identified as a "Documentation Agent" shall have or be
deemed to have any fiduciary relationship with any Lender.  Each Lender
acknowledges that it has not relied, and will not rely, on any of the Lenders so
identified in deciding to enter into this Agreement or in taking or not taking
action hereunder.

XIV.    SECTION GENERAL.

A.       Waiver; Amendments.  No delay on the part of the Agent or any
         ------------------
Lender in the exercise of any right, power or remedy shall operate as a waiver
thereof, nor shall any single or partial exercise by any of them of any right,
power or remedy preclude any other or further exercise thereof, or the exercise
of any other right, power or remedy.  No amendment, modification or waiver of,
or consent with respect to, any provision of this Agreement or the Notes shall
in any event be effective unless the same shall be in writing and signed and
delivered by Lenders having an aggregate Percentage of not less than the
aggregate Percentage expressly designated herein with respect thereto or, in the
absence of such designation as to any provision of this Agreement or the Notes,
by the Required Lenders, and then any such amendment, modification, waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given.  No amendment, modification, waiver or consent shall
change the Percentage of any Lender without the consent of such Lender.  No
amendment, modification, waiver or consent shall (i) extend the date for payment
of any principal of or interest on the Loans or any fees payable hereunder, (ii)
reduce the principal amount of any Loan, the rate of interest thereon or any
fees payable hereunder, (iii) release the U.S. Guaranty (other than with respect
to a Person which ceases to be a Subsidiary as a result of a transaction
permitted hereunder) or the Parent Guaranty or all or substantially all of the
collateral granted under the Collateral Documents or (iv) reduce the aggregate
Percentage required to effect an amendment, modification, waiver or consent
without, in each case, the consent of all Lenders.  No provision of Section 13
                                                                    ----------
or any other provision of this Agreement affecting the Agent in its capacity as
such shall be amended, modified or waived without the written consent of the
Agent.

B.       Confirmations. The Company and each Lender agree from time to time,
         -------------
upon written request received by it from the other, to confirm to the other in
writing (with a copy of each such confirmation to the Agent) the aggregate
unpaid principal amount of the Loan then outstanding under the applicable Note.

C.       Notices. Except as otherwise provided in Section 2.3, all notices
         -------                                  -----------

sent to the applicable party at its address shown on Schedule 14.3 or at such
                                                     -------------
other address as such party may, by written notice received by the other
parties, have designated as its address for such purpose.  Notices sent by
facsimile transmission shall be deemed to have been given when sent; notices
sent by mail shall be deemed to have been given three Business Days after the
date when sent by registered or certified mail, postage prepaid; and notices
sent by hand delivery or overnight courier service shall be deemed to have been
given when received.  For purposes of Section 2.3, the Agent shall be entitled
                                      -----------
to rely on telephonic instructions from any person that the Agent in good faith
believes is an authorized officer or employee of the Company, and the Company
shall hold the Agent and each other Lender harmless from any loss, cost or
expense resulting from any such reliance.

D.       Computations.  Where the character or amount of any asset or
         ------------
liability or item of income or expense is required to be determined, or any
consolidation or other accounting computation is required to be made, for the
purpose of this Agreement, such determination or calculation shall, to the
extent applicable and except as otherwise specified in this Agreement, be made
in accordance with GAAP, consistently applied; provided that if Parent notifies
                                               --------
the Agent that Parent wishes to amend any covenant in Section 10 to eliminate or
                                                      ----------
to take into account the
<PAGE>

effect of any change in GAAP on the operation of such covenant (or if the Agent
notifies Parent that the Required Lenders wish to amend Section 10 for such
                                                        ----------
purpose), then Parent's compliance with such covenant shall be determined on the
basis of GAAP as in effect immediately before the relevant change in GAAP became
effective until either such notice is withdrawn or such covenant is amended in a
manner satisfactory to Parent and the Required Lenders.

E.        Regulation U.  Each Lender represents that it in good faith is not
          ------------

security for the extension or maintenance by it of any credit provided for in
this Agreement.

F.        Costs, Expenses and Taxes.  The Company agrees to pay on demand all
          -------------------------

reasonable fees and charges of counsel for the Agent and of local counsel, if
any, who may be retained by said counsel) in connection with the preparation,
execution, delivery and administration of this Agreement, the other Loan
Documents and all other documents provided for herein or delivered or to be
delivered hereunder or in connection herewith (including any amendment,
supplement or waiver to any Loan Document), and all reasonable out-of-pocket
costs and expenses (including reasonable attorneys' fees, court costs and other
legal expenses and allocated costs of staff counsel) incurred by the Agent and
each Lender after an Event of Default in connection with the enforcement of this
Agreement, the other Loan Documents or any such other documents. In addition,
the Company agrees to pay, and to save the Agent and the Lenders harmless from
all liability for, (a) any stamp or other taxes (excluding income taxes and
franchise taxes based on net income) which may be payable in connection with the
execution and delivery of this Agreement, the borrowings hereunder, the issuance
of the Notes or the execution and delivery of any other Loan Document or any
other document provided for herein or delivered or to be delivered hereunder or
in connection herewith and (b) any fees of Parent's auditors in connection with
any reasonable exercise by the Agent and the Lenders of their rights pursuant to
Section 10.2. All obligations provided for in this Section 14.6 shall survive
------------                                       ------------
repayment of the Loans, cancellation of the Notes and any termination of this
Agreement.

G.        Judgment.  If, for the purposes of obtaining judgment in any court,
          --------
it is necessary to convert a sum due hereunder or under any other Loan Document
in one currency into another currency, the rate of exchange used shall be that
at which in accordance with normal banking procedures the Agent could purchase
the first currency with such other currency on the Business Day preceding that
on which final judgment is given. The obligation of the Company in respect of
any such sum due from it to the Agent or any Lender hereunder or under any other
Loan Document shall, notwithstanding any judgment in a currency (the "Judgment
                                                                      --------
Currency") other than that in which such sum is denominated in accordance with
--------
the applicable provisions of this Agreement (the "Agreement Currency"), be
                                                  ------------------
discharged only to the extent that on the Business Day following receipt by the
Agent or such Lender of any sum adjudged to be so due in the Judgment Currency,
the Agent or such Lender may in accordance with normal banking procedures
purchase the Agreement Currency with the Judgment Currency.  If the amount of
the Agreement Currency so purchased is less than the sum originally due to the
Agent or such Lender in the Agreement Currency, the Company agrees, as a
separate obligation and notwithstanding any such judgment, to indemnify the
Agent or such Lender against such loss.  If the amount of the Agreement Currency
so purchased is greater than the sum originally due to the
<PAGE>

Agent or such Lender in such currency, the Agent or such Lender agrees to return
the amount of any excess to the Company (or to any other Person who may be
entitled thereto under applicable law).

I.   Assignments; Participations.

1.   Assignments.  Any Lender may, with the prior written consents of the
     -----------
Company and the Agent (which consents shall not be unreasonably delayed or
withheld), at any time assign and delegate to one or more Related Funds
(provided that no written consent of the Company or the Agent shall be required
---------
in connection with any assignment and delegation by a Lender to a Related Fund),
commercial banks or other Persons (any Person to whom such an assignment and
delegation is to be made being herein called an "Assignee") all or any fraction
                                                 --------
of such Lender's Loan in a minimum aggregate amount equal to the lesser of (i)
the amount of the assigning Lender's Loan and (ii) U.S.$5,000,000; provided,
                                                                   --------
however, that (a) no assignment and delegation may be made to any Person if, at
-------
the time of such assignment and delegation, the Company would be obligated to
pay any greater amount under Section 7.5 or Section 8 to the Assignee than the
                             -----------    ---------
Company is then obligated to pay to the assigning Lender under such Sections
(and if any assignment is made in violation of the foregoing, the Company will
not be required to pay the incremental amounts); and (b) the Company and the
Agent shall be entitled to continue to deal solely and directly with such Lender
in connection with the interests so assigned and delegated to an Assignee until
the date when all of the following conditions shall have been met:

     (x)  five Business Days (or such lesser period of time as the Agent and the
assigning Lender shall agree) shall have passed after written notice of such
assignment and delegation, together with payment instructions, addresses and
related information with respect to such Assignee, shall have been given to the
Company and the Agent by such assigning Lender and the Assignee,

     (y)  the assigning Lender and the Assignee shall have executed and
delivered to the Company and the Agent an assignment agreement substantially in
the form of Exhibit H (an "Assignment Agreement"), together with any documents
            ---------      --------------------
required to be delivered thereunder, which Assignment Agreement shall have been
accepted by the Agent, and

     (z)  the assigning Lender or the Assignee shall have paid the Agent a
processing fee of U.S.$3,500.

From and after the date on which the conditions described above have been met,
(x) such Assignee shall be deemed automatically to have become a party hereto
and, to the extent that rights and obligations hereunder have been assigned and
delegated to such Assignee pursuant to such Assignment Agreement, shall have the
rights and obligations of a Lender hereunder, and (y) the assigning Lender, to
the extent that rights and obligations hereunder have been assigned and
delegated by it pursuant to such Assignment Agreement, shall be released from
its obligations hereunder.  Within five Business Days after the effectiveness of
any assignment and delegation, the Company shall execute and deliver to the
Agent (for delivery to the Assignee and the
<PAGE>

Assignor, as applicable) a new Note in the amount of the Assignee's Loan and, if
the assigning Lender continues to have a Loan hereunder, a replacement Note in
the amount of the assigning Lender's Loan. Each such Note shall be dated the
effective date of such assignment. The assigning Lender shall mark the
predecessor Note "exchanged" and deliver such Note to the Company. Any attempted
assignment and delegation not made in accordance with this Section 14.9.1
                                                           --------------
shall be null and void.


     The Company designates the Agent as its agent for maintaining a book entry
record of ownership identifying the Lenders, their respective addresses and the
amount of the respective Loans and Notes which they own.  The foregoing
provisions are intended to comply with the registration requirements in Treasury
Regulation Section 5f.103-1 so that the Loans and Notes are considered to be in
"registered form" pursuant to such regulation.

     Notwithstanding the foregoing provisions of this Section 14.9.1 or any
                                                      --------------
other provision of this Agreement, any Lender may at any time assign all or any
portion of its Loan and its Note to a Federal Reserve Bank (but no such
assignment shall release any Lender from any of its obligations hereunder).

2.   Participations.  Any Lender may at any time sell to one or more
     --------------
commercial banks or other Persons participating interests in such Lender's Loan,
the Note held by such Lender or any other interest of such Lender hereunder (any
Person purchasing any such participating interest being called a "Participant").
                                                                  -----------
In the event of a sale by a Lender of a participating interest to a Participant,
(x) such Lender shall remain the holder of its Note for all purposes of this
Agreement, (y) the Company and the Agent shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations hereunder and (z) all amounts payable by the Company shall be
determined as if such Lender had not sold such participation and shall be paid
directly to such Lender.  No Participant shall have any direct or indirect
voting rights hereunder except with respect to any of the events described in
the fourth sentence of Section 14.1.  Each Lender agrees to incorporate the
                       ------------
requirements of the preceding sentence into each participation agreement which
such Lender enters into with any Participant.  The Company agrees that if
amounts outstanding under this Agreement and the Notes are due and payable (as a
result of acceleration or otherwise), each Participant shall be deemed to have
the right of setoff in respect of its participating interest in amounts owing
under this Agreement and any Note to the same extent as if the amount of its
participating interest were owing directly to it as a Lender under this
Agreement or such Note; provided that such right of setoff shall be subject to
                        --------
the obligation of each Participant to share with the Lenders, and the Lenders
agree to share with each Participant, as provided in Section 7.4.  The Company
                                                     -----------
also agrees that each Participant shall be entitled to the benefits of Section
                                                                       -------
7.5 and Section 8 as if it were a Lender (provided that no Participant shall
---     ---------
receive any greater compensation pursuant to Section 7.5 or Section 8 than would
                                             -----------    ---------
have been paid to the participating Lender if no participation had been sold).
Each Lender which sells a participation will maintain a book entry record of
ownership identifying the Participant and the amount of such participation owned
by such Participant.  Such book entry record of ownership shall be maintained by
the Lender as agent for the Company and the Agent.

to be in "registered form" pursuant to such regulation.

                                           LITIGATION AND CONTINGENT LIABILITIES

1)  A subsidiary of the Company has been named in a complaint alleging sexual
harassment, intentional inflection of emotional distress and wrongful
termination.  The alleged acts took place prior to the Company's acquisition of
such subsidiary.  The plaintiff is seeking an aggregate of $450,000.

2)  The Company is subject to a claim of wrongful termination by one of its
branch sales manager.  The sales manager has indicated he would settle the claim
of wrongful termination for the sum of $350,000.

3)  The Company brought suit against two former shareholders relating to one of
its acquisitions, primarily alleging misrepresentation of sales and violation of
non-compete agreements.  Subsequent to the filing of the Company's suit, the
former shareholders brought suit against the Company alleging breach of
contract, breach of fiduciary duties, conversion and fraudulent
misrepresentation among others.  The Company estimates these suits could be
settled for approximately $500,000.

                                                ENVIRONMENTAL MATTERS

Valley Rentals, Inc. with branches in Longview, Vancouver, and Turnwater,
--------------------
Washington

Fill material used to level the Longview site before the building was
constructed, was later determined to be "black mud", which now is considered a
hazardous waste (generated at the Reynolds Metals aluminum foundry). The
property is listed as a state hazardous waste site. The former Underground
Storage Tanks "USTs" (removed in May 1991) have not been granted closure,
because during their removal the waste material was found. The Company has
obtained an indemnity for this matter from the seller.

Pearson Equipment Rental, Ltd., two locations in Sarnia, Ontario
------------------------------

At the Vidal Street site, there is likelihood that there remains petroleum
hydrocarbon contaminated soils in the vicinity of a former underground oil/water
separator tank and former above-ground fuel storage tanks. There were previously
USTs at the south end of the property, and there also is a suspicion that
contaminated soils may exist at this location. The purchase agreement provides
for a $200,000 holdback, to address further site assessment work and remediation
of the contamination. The Company is awaiting a proposal to conduct the
additional Phase II site assessment work.

Perco, Ltd., nine stores in Quebec and one in Ontario, Canada
-----------

Tank tightness tests and possibly Phase II site assessments need to be conducted
at five of the sites which have fuel USTs. The sellers are responsible pursuant
to the purchase agreement for the costs of these investigations and any
remediation of contamination.

Reitzel Rentals, Ltd., eleven branches in Ontario, Canada
---------------------

Five of the properties have had USTs removed, for which there is not any
documentation of the soil or groundwater quality in proximity to the former
tanks. A Phase II environmental assessment is soon to be conducted at each of
these sites to determine whether any contamination is present. The sellers are
to pay for the costs of the investigation and any subsequent remediation.

Yankee Equipment, Bloomfield, Connecticut and Pascoag, Rhode Island
----------------

There are two, 1981-vintage 10,000 gallon USTs at the Bloomfield, Connecticut
site that will need to be removed and remediated, if needed, or upgraded to meet
the December 22, 1998 federal deadline. This will be done pursuant to the stock
purchase agreement dated June 5, 1998, at the seller's expense.

There are two dry wells at the Bloomfield property that have received petroleum-
contaminated water. These currently are being investigated by an environmental
firm, and will be remediated and sealed off, as appropriate. This will be done
pursuant to the stock purchase agreement at the seller's expense.

Gaedcke Equipment Company, with branches in Dallas, Austin, Houston and
-------------------------
Beaumont, Texas

The Dallas property had a UST installed that was not registered. The seller
represented in the stock purchase agreement that these tanks meet the federal
requirements. (Also the Houston property contains two USTs and the Beaumont
facility contains one UST). These three USTs have mixed petroleum products.
Seller has agreed to indemnify the Company. The Company will expend $5,000 each
to
<PAGE>

remove these USTs for a total of $15,000 in the aggregate. Seller will be
responsible for all remediation.

There are small unregistered waste oil USTs at the Houston and Beaumont
properties, which need to be removed. The estimated cost to remove the USTs is
approximately $20,000.

Rent-It Center, Inc., Salt Lake City, Utah
--------------------

The USTs at the Rent-It Center, Inc. property on the west side of Salt Lake City
previously were removed. There remain low levels of several contaminants in soil
and groundwater on the property. However, due to considerable contamination of
groundwater in the vicinity of this property from other sources, it is unclear
that such contamination is solely from Rent-It Center, Inc.'s former USTs. An
environmental report was completed at this site in 1996 and was submitted to the
state authorities requesting the UST removal case to be considered closed. To
date, there has been no response to this request. It is unlikely further
remediation would be required. However, if continued monitoring would be
necessary, the maximum exposure is estimated to be approximately $20,000.

A-1 Rental, Story Road, San Jose, California
----------

A-1's Story Road, San Jose store was subject to the removal of USTs in 1986.
Although the local agency has advised the company on how to obtain a conditional
case closure (for cases where groundwater has not been impacted), the company
has never followed up, and the UST removal case apparently remains open. The
Company has been indemnified for any future costs associated with this matter,
and is following up with the regulatory agency to determine what future actions
may be required, on behalf of the previous owners. The maximum exposure to the
Company if it has to complete the closure is estimated to be approximately
$20,000.

Mission Valley Rentals, Inc., Osgood Road Property, Fremont, California
----------------------------

Two USTs were removed in 1990 by Mission Valley, and a soil remediation project
followed; this UST case remains open with the local program administering
agency, the Alameda County Water District (ACWD), which had requested additional
monitoring. The company has recently had groundwater wells sampled, which
indicated no remaining contamination. These results will be presented to the
ACWD with a request for case closure. The maximum exposure to the Company is
estimated to be approximately $70,000, which has been provided to the Company by
the previous owners to resolve this matter.

Ross Equipment Corporation
--------------------------

The subject property contains two, 8,000-gallon USTs that are suspected to have
leaked and which need to be removed and remediated. As is common with old USTs,
there is a significant prospect that these tanks or their piping may indeed have
leaked, and that soils and possibly groundwater will need to be remediated. The
maximum exposure to the Company is estimated to be $50,000, however, the company
has received an indemnity from the former owners.

Ray Gordon Equipment
--------------------

There are three UST's in use on the property (two 1,000-gallon UST's and one
2,000-gallon gasoline UST). It is not clear whether these UST's have leaked and
require remediation.

The maximum expense to the Company is estimated to be $225,000, however, the
Company has
<PAGE>

received on indemnity from the former owners.

Equipment Supply Company
------------------------

Two facilities in connection with this acquisition have UST's that require
upgrading or removal. The maximum exposure to the Company is estimated to be
$150,000, however, the Company has received an indemnity from the former owners.

Rental Tools & Equipment Co. International, Inc.
------------------------------------------------

There was a number of recently removed UST's from 11 sites relating to this
acquisition. The Company is awaiting test results and other documentation to
determine the necessary follow-up procedures, if any, relating to these sites.
The maximum exposure to the Company is estimated to be approximately $225,000.
In addition, the former shareholders have agreed to remove and, if necessary,
remediate 15 existing underground storage tanks at their expense.

                            Environmental Matters Relating to U.S. Rentals
                            ----------------------------------------------

The $1,072,511.31 reserve for hazardous waste on U.S. Rentals, Inc.'s financial
statements represents estimated future cost for the pulling of underground fuel
storage tanks and remediation of contaminated soil.

Remediation Cost:
----------------

Over the past 11 years, U.S. Rentals has pulled 125 underground storage tanks.
The average remediation cost per tank is $14,297.20.

U.S. Rentals currently owns 5 double-walled underground storage tanks.  U.S.
Rentals has seven sites with ongoing remediation.

Total Hazardous Waste Reserve Breaks Down As Follows:
----------------------------------------------------

Projected remediation cost on remaining underground storage tanks:  $82,500.00.

Projected remediation on sites in progress of remediation:  $473,412.20.

Environmental liability waste reserve:  $539,880.80.

Total A/P accrued liabilities waste reserve:  $1,072,511.31.

Based on the above, it is my opinion that the reserve of hazardous waste as of
September 24, 1998 is adequate and no additional reserve or disclosure is
required.

Projected reserves on sites in process of remediation total $423,412.20 and
breaks down as follows:

Downey:
------

The current remediation costs to date are $8,152.88.  After monitoring wells
were installed, the ground water tested Benzine at 0.8 parts per billion.  1.0
parts per billion is the limit.  Therefore, our consultant is submitting for
closure.  If the local board still has an issue in regards to the soil
contamination, our consultant will transfer the case to the regional board for
consideration of closure, since the regional
<PAGE>

board is more lenient in regards to soil issues. The current remediation reserve
for the Downey facility is $30,000.

Long Beach:
----------

U.S. rentals has relocated from the 5640 Cherry Avenue location. U.S. Rentals
has paid $98,435.59 in remediation cost at this site. The soil may be excavated
and disposed of from this facility if required by the City of Long Beach. The
current reserves are $138,412.20.

Fullerton:
---------

Six underground storage tanks were pulled from this facility. The contamination
was minimal. Contaminated soil was removed from the facility and the case has
been submitted for closure. The current reserves for administrative costs for
closure are $10,000.00.

Stockton:
--------

U.S. Rentals has spent $100,269.39 in remediation costs associated with this
site. U.S. Rentals continues to test the monitoring wells. The current
remediation reserve on this facility is $150,000.

Tucson:
------

In November of 1997, U.S. Rentals pulled an oil tank from this facility and
found contamination. It is anticipated that the remediation exposure will be low
due to the level of the ground water. U.S. rentals has reserved $15,000 for its
remediation at this facility.

San Francisco:
-------------

U.S. Rentals recently removed five active underground storage tanks at this
facility, and contamination was discovered. U.S. Rentals has reserved $80,000
towards remediation costs associated with this facility.

Keller:
------

During construction a contractor discovered 10 to 12 55-gallon drums and
contaminated soil. Reserves set for removal and disposal of 850 cubic yards of
contaminated soil. To prevent delays in construction, the contaminated soil has
been removed and stockpiled on plastic until disposal can take place. $50,000 to
haul and dispose of contaminated soil. Remediation cost to remove contaminated
soil, $38,029.14. Reserved at $50,000.00 to complete closure.

                                            AMENDMENT TO INTERCREDITOR AGREEMENT

                                                  Dated as of May 12, 2000




          Reference is made to the Intercreditor Agreement (the "Intercreditor
                                                                 -------------
Agreement") dated as of September 29, 1998 among Bank of America, N.A. (formerly
---------
known as Bank of America National Trust and Savings Association), as U.S. Agent,
Bank of America, N.A., as Term Agent, various other senior secured creditors of
the Company and Bank of America, N.A., as Collateral Agent.  Capitalized terms
not defined herein are used as defined in the Intercreditor Agreement.

          Each of the undersigned hereby agrees that subsection 3(f) of the
Intercreditor Agreement is amended in its entirety to read as follows:

          "(f)  The Collateral Agent may (and shall at the request of any
          Grantor), without the approval of any other Benefited Party, (x)
          release any Collateral under any Security Document which is permitted
          to be sold or disposed of or otherwise released pursuant to the Credit
          Agreement, the Term Loan Agreement and any applicable Permitted Senior
          Secured Debt Agreement and execute and deliver such releases as may be
          necessary to terminate of record the Collateral Agent's security
          interest (for the benefit of the Benefited Parties) in such
          Collateral, (y) release any Grantor from its obligations under the
          U.S. Guaranty which is permitted to be released pursuant to the Credit
          Agreement, the Term Loan Agreement and any applicable Permitted Senior
          Secured Debt Agreement and (z) subordinate its interest in any
          Collateral to the holder of any Lien on such Collateral which is
          permitted by clause (d) or (h) of Section 10.8 of the Credit
          Agreement, clause (d) or (h) of Section 10.8 of the Term Loan
          Agreement and the comparable provisions of each Permitted Senior
          Secured Debt Agreement.  In determining whether any such release or
          subordination is permitted, the Collateral Agent may (I) rely, as to
          factual matters, on a Certificate from the Company and (II) may (but
          shall not be obligated to) seek (and, if obtained, rely upon)
          instructions from the Required Banks (as to whether any such release
          is permitted under the Credit Agreement), from the Required Term
          Lenders (as to whether any such release is permitted under the Term
          Loan Agreement) and from the Required Permitted Creditors under each
          Permitted Senior Secured Debt Agreement or group of related Permitted
          Senior Secured Debt Agreements (as to whether any such release is
          permitted under the applicable Agreement or Agreements).  In addition,
          the Collateral Agent may release all Collateral upon receipt of (i)
          written notice from the U.S. Agent that all Credit Obligations have
          been paid in full (other than contingent obligations (A) in respect of
          Letters of Credit which have been cash collateralized or otherwise
          provided for to the satisfaction of the Issuing Bank (as defined in
          the Credit Agreement) and (B) arising under provisions of the Credit
          Agreement which by their terms survive
<PAGE>

          termination thereof) and all commitments to create Credit Obligations
          have been terminated, (ii) written notice from the Term Agent that all
          Term Obligations have been paid in full (other than any Term
          Obligations arising under provisions of the Term Loan Agreement which
          by their terms survive termination thereof), (iii) written notice from
          each holder of Hedging Obligations that such Hedging Obligations have
          been paid in full or otherwise provided for to the satisfaction of
          such holder (it being understood that if the Collateral Agent notifies
          the Banks, the Term Lenders and the Permitted Creditors that it
          intends to release the Collateral pursuant to this sentence, the
          Collateral Agent may conclusively presume that there are no Hedging
          Obligations other than those of which the Collateral Agent receives
          notice not later than the later of five business days after notice is
          sent by the Collateral Agent of such intended release and the business
          day before the date on which such release occurs), (iv) written notice
          from each Permitted Creditor (or, in the case of any group of
          Permitted Creditors, an agent therefor) that all Permitted Senior
          Secured Debt Obligations owed to such Permitted Creditor (or group of
          Permitted Creditors) have been paid in full (other than any Permitted
          Senior Secured Debt Obligations arising under provisions of any
          Permitted Senior Secured Debt Document which by their terms survive
          termination thereof) and (v) payment of all other Benefited
          Obligations owed to the Collateral Agent or of which the Collateral
          Agent has received written notice."

          IN WITNESS WHEREOF, each of the undersigned has caused this amendment
to be executed and delivered by its duly authorized representative as of the
date hereof.
