1. INTRODUCTION

The Registrant's initial public offering ("IPO") was declared effective on 
February 20, 1997. Prior to the IPO, the equipment rental business was operated 
by Ayr, Inc., a California corporation (the "Predecessor") that was treated as 
an S corporation under the Internal Revenue Code. The Registrant did not have 
any operations prior to its IPO. Prior to the closing of the IPO, the 
Predecessor transferred substantially all of its operating assets and associated
liabilities to the Registrant in exchange for 20,748,975 shares of Common Stock 
of the Registrant, representing all of the Registrant's outstanding capital 
stock prior to the IPO. The Predecessor retained only non-operating assets and 
liabilities, including approximately $25.7 million of notes receivable from 
related parties and approximately $24.4 million of notes payable to related 
parties. These transactions are referred to as the "Recapitalization" in this 
report.

Unless otherwise indicated, the "Company" means the Predecessor prior to the IPO
and the Registrant on or after the IPO.

total revenues for the same period in 1997.  Of the $27.3 million increase in
rental revenue, $18.2 million was due primarily to 44 new locations which were
added subsequent to December 31, 1996.  The remaining increase of approximately
$9.1 million was due to increased equipment rental fleet at existing locations.
Rental revenue as a percentage of total revenue decreased due to the Company's
efforts to take advantage of opportunities in the used equipment sales and
merchandise and new equipment sales markets.  In addition to the above, severe
weather conditions along the West Coast related to El Nino have slowed
construction activity which caused a less than expected rental volume.  Used
rental equipment sales increased 81.4% to $13.1 million or 10.8% of total
revenues for the three months ended March 31, 1998 from $7.2 million or 8.9% of
total revenues for the same period in 1997 due to increased customer demand,
increased sales efforts across the nation and alternative financing sources for
customers such as various leasing programs.  Merchandise and new equipment sales
increased 75.3% for the first three months ended March 31, 1998 to $14.8 million
or 12.3% of total revenues as compared to $8.5 million or 10.4% of total
revenues for the same period in 1997.  This increase was primarily due to the
increase in the related rental revenue, expansion of product line within resale
showrooms, as well as a 55% increase in the number of operating locations since
December 31, 1996.

  Gross Profit.  Gross profit for the three months ended March 31, 1998
increased 46.7% to $26.6 million from $18.1 million for the same period in 1997
primarily due to increased rental revenue and certain economies achieved through
the Company's continued investment in new equipment.  Gross profit from rentals
increased 46.8% to $49.2 million for the three month ended March 31, 1998 from
$33.5 million for the same period in 1997 as a result of higher rental volume.
Rental gross profit as a percent of rental revenue increased to 53.1% for the
three months ended March 31, 1998 from 51.3% for the same period in 1997. This
increase was due primarily to a 41.8% increase in rental revenue partially
offset by an increase in rental equipment expense of 25.7% due to the impact of
increased rental volume.  Gross profit from sales of used rental equipment
increased 77.6% to $6.8 million from $3.8 million for the same period in 1997
due to increased demand for used equipment, but decreased as a percent of such
sales due to the mix of sales toward later model equipment.  Gross profit from
sales of merchandise and new equipment increased 102.5% for the three months
ended March 31, 1998 as compared to the same period in 1997 due to the impact of
increased rental volume on the sale of merchandise, a concerted effort to expand
the product line and resale showrooms, and an increase in new equipment sales
and customer volume.  Gross profit on the sale of merchandise and new equipment
also increased as a percentage of total revenue.  Gross profit was negatively
impacted by an increase in direct operating expenses for the three months ended
March 31, 1998 which increased 57.6% to $33.4 million as compared to $21.2
million for the same period in 1997.  The increase reflects staffing and
facilities costs resulting from an increased number of rental yards and higher
maintenance costs necessary to support the increased size of the rental fleet.

  Selling, General and Administrative Expense.  Selling, general and
administrative expense for the three months ended March 31, 1998 increased 51.3%
to $11.4 million compared to $7.6 million for the same period in 1997. The
increase was primarily due to higher advertising, bad debt and profit sharing
expense for the three months ended March 31, 1998 as compared to the same period
in 1997.  As a percentage of total revenue, selling, general and administrative
expense increased slightly to 9.4% for the three months ended March 31, 1998
from 9.3% for the same period in 1997.  The small increase relates to
efficiencies in operations and realizing certain economies of scale related to
the increase in the number of locations as described above.

  Termination cost of deferred compensation agreements.   Other operating
expense for the three months ended March 31, 1997 consists of a one-time
compensation expense related to the termination of the Predecessor's deferred
incentive compensation agreements just prior to the Initial Public Offering
(IPO) in February 1997.

  Other Expense, net.  Substantially all other income and expense items for the
three months ended March 31, 1997 are related to investments and charitable
contributions made at the direction of the majority stockholder of the
Predecessor prior to the IPO.  No such expense was incurred by the Company in
the current quarter.

  Interest Expense, net.  Interest expense increased 119.1% to $3.4 million for
the three months ended March 31, 1998 from $1.6 million for the same period in
1997.  The increase was primarily the result of higher average debt outstanding
under the credit facility during the three months ended March 31, 1998 as
compared to same period of 1997.  The increase in average debt outstanding was
the result of the Company's significant investment in capital expenditures.

  Income Taxes.  Prior to its IPO, the Company was taxed as an S corporation for
federal and state purposes.  In February 1997, the Company incurred a one-time
$7.5 million deferred tax charge to reflect the recognition of a deferred tax
liability relating to federal and state income taxes as if the Company had been
taxed as a C corporation rather than as an S corporation since inception.
Subsequent to February 26, 1997, the Company's income was taxed as a C
corporation at an effective rate from 40.0 TO 40.2%.

LIQUIDITY AND CAPITAL RESOURCES

  The Company received net proceeds of $186.0 million from the sale of
10,000,000 shares of its common stock on February 26, 1997.  A portion of the
net proceeds from the IPO was used to repay all of the senior notes and
borrowings under the Company's prior credit facility. In conjunction with the
IPO, the Company entered into a new credit facility which provides availability
of up to $300.0 million with its existing lenders (the "Credit Facility").

  The Company has primarily used cash to purchase rental equipment and acquire
and start-up rental yards. The Company historically has financed its cash
requirements primarily through net cash provided by operating activities and
borrowings under its Credit Facility. In addition to the Company's Credit
Facility, the Company completed a $252.0 million private placement of senior
unsecured notes on April 28, 1998.  The Company believes that cash flow from
operations, availability under its Credit Facility and the debt offering will be
sufficient to support its operations, expansion and liquidity requirements for
at least the next 12 months.

                                MARCH 31, 1998

  For the first quarter of 1998, the Company's operating activities before 
changes in operating assets and liabilities provided net cash flow of $24.6 
million for the three months ended March 31, 1998 as compared to $.1 million for
the same period in 1997. The $24.5 million increase was primarily due to the 
absence of the termination cost of deferred compensation agreements which were 
paid during the first quarter of 1997.

  Net cash used in investing activities was $79.5 million for the three months
ended March 31, 1998 as compared to $29.4 million for the same period in 1997
due to increased purchases of rental equipment, acquisition of one rental
operation, and investment in property and equipment, partially offset by
increased sales of used rental equipment. The increase in rental fleet relates
to newly opened or acquired yards and the continued expansion of rental fleet at
existing locations.  Rental equipment purchases for the three months ended March
31, 1998 were $75.4 million as compared to $28.3 million for the same period in
1997.

  Net cash provided by financing activities was $60.1 million for the three
months ended March 31,  1998 as compared to $32.2 million for the same period in
1997. The principal causes for the variation between periods was the receipt of
the net proceeds on borrowings under the Company's Credit Facility and proceeds
from a note payable to a related party.

Certain Risk Factors That May Impact Future Operating Results

  Statements in this report may contain forward-looking statements that
represent the Company's expectations or beliefs concerning future events,
including but not limited to the sufficiency of the Company's cash to meet
expected capital expenditures and interest expense.

  The Company cautions that these statements are qualified by important factors
that could cause actual results to differ from those in the forward-looking
statements:  The Company's ability to acquire or start more rental yards and the
timing, pricing and related costs of the acquisitions and openings, the
effective integration of the acquired business and new yards, variations in
seasonal rental patterns principally due to the effect of weather on
construction activity, increased competition due to larger companies expanding
into previously less competitive markets, the cyclical nature of the equipment
rental industry, the timing and financing of capital expenditures for fleet
expansions, and general economic conditions in the Company's markets including
the possible impact of interest rate fluctuations.  In addition, the market
price of the Company's common stock could be subject to significant variation
due to fluctuations in the Company's operating results, changes in earnings
estimates by securities analysts and other factors.

  Fluctuations in Quarterly Operating Results. The Company has experienced
fluctuations in operating results in interim periods in certain geographic
regions due to seasonality. Weather conditions, such as El Nino, sometimes
affect quarterly revenues. As a result, the Company may not learn of revenue
shortfalls until late in the quarter. The Company's operating expenses are based
in part on its expectations for future revenues and

are relatively fixed in the short term. Any revenue shortfall below expectations
could have an immediate and significant adverse effect on results of operations.

To Each of the Purchasers listed
 in the attached Schedule A:

Ladies and Gentlemen:

     U.S. Rentals, Inc., a Delaware corporation (the "Company"), agrees with you
as follows:

Section 1.  Authorization of Notes.

     The Company will authorize the issue and sale of $252,000,000 aggregate

(respectively, the "Series A Notes", the "Series B Notes" and the "Series C
Notes", and collectively, the "Notes"), such terms to include any such notes
issued in substitution therefor pursuant to SECTION 13 of this Agreement or the
Other Agreements (as hereinafter defined).  The Series A Notes shall be
substantially in the form set out in EXHIBIT 1A, the Series B Notes shall be
substantially in the form set out in EXHIBIT 1B, and the Series C Notes shall be
substantially in the form set out in EXHIBIT 1C, in each case with such changes
therefrom, if any, as may be approved by you and the Company.  Certain
capitalized terms used in this Agreement are defined in SCHEDULE B; references
to a "SCHEDULE" or an "EXHIBIT" are, unless otherwise specified, to a SCHEDULE
or an EXHIBIT attached to this Agreement.

Section 2.  Sale and Purchase of Notes.

     Subject to the terms and conditions of this Agreement, the Company will
issue and sell to you and you will purchase from the Company, at the Closing
provided for in SECTION 3, Notes in the principal amount and of the Series
specified opposite your name in SCHEDULE A at the purchase price of 100% of the
principal amount thereof.  Contemporaneously with entering into 
<PAGE>
 
this Agreement, the Company is entering into separate Note Purchase Agreements
(the "Other Agreements") identical with this Agreement with each of the other
purchasers named in SCHEDULE A (the "Other Purchasers"), providing for the sale
at such Closing to each of the Other Purchasers of Notes in the principal amount
and of the Series specified opposite its name in SCHEDULE A. Your obligation
hereunder, and the obligations of the Other Purchasers under the Other
Agreements, are several and not joint obligations, and you shall have no
obligation under any Other Agreement and no liability to any Person for the
performance or nonperformance by any Other Purchaser thereunder.

Section 3.  Closing.

     The sale and purchase of the Notes to be purchased by you and the Other
Purchasers shall occur at the offices of Chapman and Cutler, 111 W. Monroe
Street, Chicago, Illinois 60603, at 10:00 a.m. Chicago time, at a closing (the
"Closing") on April 28, 1998 or on such other Business Day thereafter on or
prior to April 30, 1998 as may be agreed upon by the Company and you and the
Other Purchasers.  At the Closing the Company will deliver to you the Notes to
be purchased by you in the form of a single Note (or such greater number of
Notes in denominations of at least $500,000 as you may request) dated the date
of the Closing and registered in your name (or in the name of your nominee),
against delivery by you to the Company or its order of immediately available
funds in the amount of the purchase price therefor by wire transfer of
immediately available funds for the account of the Company to account number
1233-1-13468 at Bank of America, Concord, California, ABA/Routing Number 121-
000-358.  If at the Closing the Company shall fail to tender such Notes to you
as provided above in this SECTION 3, or any of the conditions specified in
SECTION 4 shall not have been fulfilled to your satisfaction, you shall, at your
election, be relieved of all further obligations under this Agreement, without
thereby waiving any rights you may have by reason of such failure or such
nonfulfillment.

Section 4.  Conditions to Closing.

     Your obligation to purchase and pay for the Notes to be sold to you at the
Closing is subject to the fulfillment to your satisfaction, prior to or at the
Closing, of the following conditions:

warranties of the Company in this Agreement shall be correct when made and at
the time of the Closing.

     Section 4.2.  Performance; No Default.  The Company shall have performed

contemplated by SCHEDULE 5.14), no Default or Event of Default shall have
occurred and be continuing. Neither the Company nor any Subsidiary shall have
entered into any transaction since the date of the Memorandum that would have
been prohibited by SECTIONS 10.3, 10.4, 10.5 or 10.6 hereof had such SECTIONS
applied since such date.

     Section 4.3.  Compliance Certificates.

form and substance satisfactory to you, dated the date of the Closing (a) from
O'Melveny & Myers LLP, counsel for the Company, covering the matters set forth

contemplated hereby as you or your counsel may reasonably request (and the
Company hereby instructs its counsel to deliver such opinion to you) and (b)
from Chapman and Cutler, your special counsel in connection with such
transactions, substantially in the form set forth in EXHIBIT 4.4(B) and covering
such other matters incident to such transactions as you may reasonably request.

     Section 4.5.  Purchase Permitted By Applicable Law, Etc.  On the date of
the Closing your purchase of Notes shall (a) be permitted by the laws and
regulations of each jurisdiction to which you are subject, without recourse to
provisions (such as Section 1405(a)(8) of the New York Insurance Law) permitting
limited investments by insurance companies without restriction as to the
character of the particular investment, (b) not violate any applicable law or
regulation (including, without limitation, Regulation T, U or X of the Board of
Governors of the Federal Reserve System) and (c) not subject you to any tax,
penalty or liability under or pursuant to any applicable law or regulation,
which law or regulation was not in effect on the date hereof. If requested by
you, you shall have received an Officer's Certificate certifying as to such
matters of fact as you may reasonably specify to enable you to determine whether
such purchase is so permitted.

     Section 4.6.  Sale of Other Notes.  Contemporaneously with the Closing, the
Company shall sell to the Other Purchasers, and the Other Purchasers shall
purchase, the Notes to be purchased by them at the Closing as specified in
SCHEDULE A.

                                      -3-
<PAGE>
 
     Section 4.7.  Payment of Special Counsel Fees.  Without limiting the
provisions of SECTION 15.1, the Company shall have paid on or before the Closing
the fees, charges and disbursements of your special counsel referred to in
SECTION 4.4 to the extent reflected in a statement of such counsel rendered to
the Company at least one Business Day prior to the Closing.

     Section 4.8.  Private Placement Number.  A Private Placement Number issued
by Standard & Poor's CUSIP Service Bureau (in cooperation with the Securities
Valuation Office of the National Association of Insurance Commissioners) shall
have been obtained for each Series of the Notes.

     Section 4.9.  Changes in Corporate Structure.  Except as specified in
SCHEDULE 4.9, the Company shall not have changed its jurisdiction of
incorporation or been a party to any merger or consolidation and shall not have
succeeded to all or any substantial part of the liabilities of any other entity,
at any time following the date of the most recent financial statements referred
to in SCHEDULE 5.5.

     Section 4.10.  Funding Instructions.  At least three Business Days prior to
the date of the Closing, you shall have received written instructions executed

funds and setting forth (1) the name and address of the transferee bank, (2)

the purchase price for the Notes is to be deposited, and (4) the name and
telephone number of the account representative responsible for verifying receipt
of such funds.

     Section 4.11.  Proceedings and Documents.  All corporate and other
proceedings in connection with the transactions contemplated by this Agreement
and all documents and instruments incident to such transactions shall be

of such documents as you or they may reasonably request.

Section 5.  Representations and Warranties of the Company.

     The Company represents and warrants to you that:

     Section 5.1.  Organization; Power and Authority.  The Company is a
corporation duly organized, validly existing and in good standing under the laws
of its jurisdiction of incorporation, and is duly qualified as a foreign
corporation and is in good standing in each jurisdiction in which such
qualification is required by law, other than those jurisdictions as to which the
failure to be so qualified or in good standing could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect. The Company
has the

                                      -4-
<PAGE>
 
corporate power and authority to own or hold under lease the properties it
purports to own or hold under lease, to transact the business it transacts and
proposes to transact, to execute and deliver this Agreement and the Other
Agreements and the Notes and to perform the provisions hereof and thereof.

     Section 5.2.  Authorization, Etc.  This Agreement, the Other Agreements and
the Notes have been duly authorized by all necessary corporate action on the
part of the Company, and this Agreement constitutes, and upon execution and
delivery thereof each Note will constitute, a legal, valid and binding
obligation of the Company enforceable against the Company in accordance with its
terms, except as such enforceability may be limited by (a) applicable
bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting the enforcement of creditors' rights generally and (b) general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

     Section 5.3.  Disclosure.  The Company, through its agents, Salomon Smith
Barney, BancAmerica Robertson Stephens, and NationsBanc Montgomery Securities
LLC, have delivered to you and each Other Purchaser a copy of a Confidential
Memorandum, dated March 1998 (the "Memorandum"), relating to the transactions
contemplated hereby. The Memorandum fairly describes, in all material respects,
the general nature of the business and principal properties of the Company and
its Subsidiaries. This Agreement, the Schedules hereto, the Memorandum, the
documents, certificates or other writings delivered to you by or on behalf of
the Company in connection with the transactions contemplated hereby and the
financial statements listed in SCHEDULE 5.5, taken as a whole, do not contain
any untrue statement of a material fact or omit to state any material fact
necessary to make the statements therein not misleading in light of the
circumstances under which they were made. Except as disclosed in the Memorandum,
or in one of the documents, certificates or other writings identified therein,
or in the financial statements listed in SCHEDULE 5.5, since December 31, 1997,
there has been no change in the financial condition, operations, business,
properties or prospects of the Company or any Subsidiary except changes that
individually or in the aggregate could not reasonably be expected to have a
Material Adverse Effect. There is no fact known to the Company that could
reasonably be expected to have a Material Adverse Effect that has not been set
forth herein or in the Memorandum or in the other documents, certificates and
other writings delivered to you by or on behalf of the Company specifically for
use in connection with the transactions contemplated hereby.

     Section 5.4. Organization and Ownership of Shares of Subsidiaries;
Affiliates.  (a) SCHEDULE 5.4 contains (except as noted therein) complete and
correct lists (i) of the Company's Subsidiaries, showing, as to each Subsidiary,
the correct name thereof, the jurisdiction of its organization, and the
percentage of shares of each class of its capital stock or similar equity
interests outstanding owned by the Company and each other Subsidiary, (ii) of
the

                                      -5-
<PAGE>
 
Company's Affiliates, other than Subsidiaries, and (iii) of the Company's
directors and senior officers.  Schedule 5.4 also identifies those Subsidiaries
which have been designated Restricted Subsidiaries and those Subsidiaries which
constitute Material Subsidiaries at the date of the Closing.

     (b) All of the outstanding shares of capital stock or similar equity
interests of each Restricted Subsidiary shown in SCHEDULE 5.4 as being owned by
the Company and its Restricted Subsidiaries have been validly issued, are fully
paid and nonassessable and are owned by the Company or another Restricted
Subsidiary free and clear of any Lien (except as otherwise disclosed in SCHEDULE
5.4).

     (c) Each Restricted Subsidiary identified in SCHEDULE 5.4 is a corporation
or other legal entity duly organized, validly existing and in good standing
under the laws of its jurisdiction of organization, and is duly qualified as a
foreign corporation or other legal entity and is in good standing in each
jurisdiction in which such qualification is required by law, other than those
jurisdictions as to which the failure to be so qualified or in good standing
could not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect. Each such Restricted Subsidiary has the corporate or
other power and authority to own or hold under lease the properties it purports
to own or hold under lease and to transact the business it transacts and
proposes to transact.

     (d) No Restricted Subsidiary is a party to, or otherwise subject to, any
legal restriction or any agreement (other than the agreements listed on SCHEDULE
5.4 and customary limitations imposed by corporate law statutes) restricting the
ability of such Subsidiary to pay dividends out of profits or make any other
similar distributions of profits to the Company or any of its Restricted
Subsidiaries that owns outstanding shares of capital stock or similar equity
interests of such Restricted Subsidiary.

     Section 5.5.  Financial Statements.  The Company has delivered to each
Purchaser copies of the financial statements of the Company and its Subsidiaries
listed on SCHEDULE 5.5. All of said financial statements (including in each case
the related schedules and notes) fairly present in all material respects the
consolidated financial position of the Company and its Subsidiaries as of the
respective dates specified in such financial statements and the consolidated
results of their operations and cash flows for the respective periods so
specified and have been prepared in accordance with GAAP consistently applied
throughout the periods involved except as set forth in the notes thereto
(subject, in the case of any interim financial statements, to normal year-end
adjustments).

     Section 5.6.  Compliance with Laws, Other Instruments, Etc.  The execution,
delivery and performance by the Company of this Agreement and the Notes will not
(i) contravene, result 

                                      -6-
<PAGE>
 
in any breach of, or constitute a default under, or result in the creation of
any Lien in respect of any property of the Company or any Restricted Subsidiary
under, any indenture, mortgage, deed of trust, loan, purchase or credit
agreement, lease, corporate charter or by-laws, or any other agreement or
instrument to which the Company or any Restricted Subsidiary is bound or by
which the Company or any Restricted Subsidiary or any of their respective
properties may be bound or affected, (ii) conflict with or result in a breach of
any of the terms, conditions or provisions of any order, judgment, decree, or
ruling of any court, arbitrator or Governmental Authority applicable to the
Company or any Restricted Subsidiary or (iii) violate any provision of any
statute or other rule or regulation of any Governmental Authority applicable to
the Company or any Subsidiary.

     Section 5.7.  Governmental Authorizations, Etc.  No consent, approval or
authorization of, or registration, filing or declaration with, any Governmental
Authority is required in connection with the execution, delivery or performance
by the Company of this Agreement or the Notes.

     Section 5.8.  Litigation; Observance of Agreements, Statutes and Orders.  
(a) There are no actions, suits or proceedings pending or, to the knowledge of
the Company, threatened against or affecting the Company or any Restricted
Subsidiary or any property of the Company or any Restricted Subsidiary in any
court or before any arbitrator of any kind or before or by any Governmental
Authority that, individually or in the aggregate, could reasonably be expected
to have a Material Adverse Effect.

     (b) The Company is not in default in the payment of principal or interest
on any indebtedness for borrowed money described in SCHEDULE 5.15.  Neither the
Company nor any Restricted Subsidiary is in default under any term of any
agreement or instrument to which it is a party or by which it is bound, or any
order, judgment, decree or ruling of any court, arbitrator or Governmental
Authority or is in violation of any applicable law, ordinance, rule or
regulation (including without limitation Environmental Laws) of any Governmental
Authority, which default or violation, individually or in the aggregate, could
reasonably be expected to have a Material Adverse Effect.

     Section 5.9.  Taxes.  The Company and its Restricted Subsidiaries have
filed all tax returns that are required to have been filed in any jurisdiction,
and have paid all taxes shown to be due and payable on such returns and all
other taxes and assessments levied upon them or their properties, assets, income
or franchises, to the extent such taxes and assessments have become due and
payable and before they have become delinquent, except for any taxes and
assessments (a) the amount of which is not individually or in the aggregate
Material or (b) the amount, applicability or validity of which is currently
being contested in good faith by appropriate proceedings and with respect to
which the Company or a Restricted Subsidiary, as the case may 

                                      -7-
<PAGE>
 
be, has established adequate reserves in accordance with GAAP. The Company knows
of no basis for any other tax or assessment that could reasonably be expected to
have a Material Adverse Effect. The charges, accruals and reserves on the books
of the Company and its Subsidiaries in respect of Federal, state or other taxes
for all fiscal periods are adequate. The Federal income tax liabilities of the
Company and its Restricted Subsidiaries have been determined by the Internal
Revenue Service and paid for all fiscal years up to and including the fiscal
year ended December 31, 1993. The Federal income tax liabilities of AYR, Inc.
(formerly known as USR Holdings, Inc.), a California corporation and predecessor
to the Company, have been determined by the Internal Revenue Service and paid
for all fiscal years up to and including the fiscal year ended December 31,
1992.

     Section 5.10.  Title to Property; Leases.  The Company and its Restricted
Subsidiaries have good and sufficient title to their respective properties that
individually or in the aggregate are Material, including all such properties
reflected in the most recent audited balance sheet referred to in SECTION 5.5 or
purported to have been acquired by the Company or any Restricted Subsidiary
after said date (except as sold or otherwise disposed of in the ordinary course
of business), in each case free and clear of Liens prohibited by this Agreement.
All leases that individually or in the aggregate are Material are valid and
subsisting and are in full force and effect in all material respects.

     Section 5.11.  Licenses, Permits, Etc.  Except as disclosed in SCHEDULE
5.11,

     (a) the Company and its Restricted Subsidiaries own or possess all
licenses, permits, franchises, authorizations, patents, copyrights, service
marks, trademarks and trade names, or rights thereto, that individually or in
the aggregate are Material, without known conflict with the rights of others;

     (b) to the best knowledge of the Company, no product of the Company
infringes in any material respect any license, permit, franchise, authorization,
patent, copyright, service mark, trademark, trade name or other right owned by
any other Person; and

     (c) to the best knowledge of the Company, there is no Material violation
by any Person of any right of the Company or any of its Subsidiaries with
respect to any patent, copyright, service mark, trademark, trade name or other
right owned or used by the Company or any of its Restricted Subsidiaries.

     Section 5.12.  Compliance with ERISA.  (a) The Company and each ERISA
Affiliate have operated and administered each Plan in compliance with all
applicable laws except for such instances of noncompliance as have not resulted
in and could not reasonably be expected to result in a Material Adverse Effect.
Neither the Company nor any ERISA Affiliate has incurred 

                                      -8-
<PAGE>
 
any liability pursuant to Title I or IV of ERISA or the penalty or excise tax
provisions of the Code relating to employee benefit plans (as defined in Section
3 of ERISA), and no event, transaction or condition has occurred or exists that
could reasonably be expected to result in the incurrence of any such liability
by the Company or any ERISA Affiliate, or in the imposition of any Lien on any
of the rights, properties or assets of the Company or any ERISA Affiliate, in
either case pursuant to Title I or IV of ERISA or to such penalty or excise tax
provisions or to Section 401(a)(29) or 412 of the Code, other than such
liabilities or Liens as would not be individually or in the aggregate Material.

     (b) The present value of the aggregate benefit liabilities under each of
the Plans (other than Multiemployer Plans), determined as of the end of such
Plan's most recently ended plan year on the basis of the actuarial assumptions
specified for funding purposes in such Plan's most recent actuarial valuation
report, did not exceed the aggregate current value of the assets of such Plan
allocable to such benefit liabilities.  The term "benefit liabilities" has the
meaning specified in Section 4001 of ERISA and the terms "current value" and
"present value" have the meaning specified in section 3 of ERISA.

     (c) The Company and its ERISA Affiliates have not incurred withdrawal
liabilities (and are not subject to contingent withdrawal liabilities) under
Section 4201 or 4204 of ERISA in respect of Multiemployer Plans that
individually or in the aggregate are Material.

     (d) The expected post-retirement benefit obligation (determined as of the
last day of the Company's most recently ended fiscal year in accordance with
Financial Accounting Standards Board Statement No. 106, without regard to
liabilities attributable to continuation coverage mandated by Section 4980B of
the Code) of the Company and its Subsidiaries is not Material.

     (e) The execution and delivery of this Agreement and the issuance and sale
of the Notes hereunder will not involve any transaction that is subject to the
prohibitions of Section 406 of ERISA or in connection with which a tax could be
imposed pursuant to Section 4975(c)(1)(A)-(D) of the Code. The representation by

upon and subject to the accuracy of your representation in SECTION 6.2 as to the
sources of the funds used to pay the purchase price of the Notes to be purchased
by you.

     Section 5.13.  Private Offering by the Company.  Neither the Company nor
anyone acting on its behalf has offered the Notes or any similar securities for
sale to, or solicited any offer to buy any of the same from, or otherwise
approached or negotiated in respect thereof with, any Person other than you, the
Other Purchasers and not more than 110 other Institutional Investors, each of

of Section 5 of the Securities Act.

     Section 5.14.  Use of Proceeds; Margin Regulations.  The Company will apply
the proceeds of the sale of the Notes as set forth in SCHEDULE 5.14. No part of
the proceeds from the sale of the Notes hereunder will be used, directly or
indirectly, for the purpose of buying or carrying any margin stock within the
meaning of Regulation U of the Board of Governors of the Federal Reserve System
(12 CFR 221), or for the purpose of buying or carrying or trading in any
securities under such circumstances as to involve the Company in a violation of
Regulation X of said Board (12 CFR 224) or to involve any broker or dealer in a
violation of Regulation T of said Board (12 CFR 220). Margin stock does not
constitute more than 1% of the value of the consolidated assets of the Company
and its Subsidiaries and the Company does not have any present intention that
margin stock will constitute more than 1% of the value of such assets. As used
in this Section, the terms "margin stock" and "purpose of buying or carrying"
shall have the meanings assigned to them in said Regulation U.

     Section 5.15.  Existing Indebtedness; Future Liens.  (a) SCHEDULE 5.15 sets

been no Material change in the amounts, interest rates, sinking funds,
installment payments or maturities of the Indebtedness of the Company or its
Restricted Subsidiaries. Neither the Company nor any Restricted Subsidiary is in
default, and no waiver of default is currently in effect, in the payment of any
principal or interest on any Indebtedness of the Company or such Restricted
Subsidiary and no event or condition exists with respect to any Indebtedness of
the Company or any Restricted Subsidiary that would permit (or that with notice
or the lapse of time, or both, would permit) one or more Persons to cause such
Indebtedness to become due and payable before its stated maturity or before its
regularly scheduled dates of payment.

     (b) Except as disclosed in SCHEDULE 5.15, neither the Company nor any
Restricted Subsidiary has agreed or consented to cause or permit in the future
(upon the happening of a contingency or otherwise) any of its property, whether
now owned or hereafter acquired, to be subject to a Lien not permitted by
SECTION 10.4.

     Section 5.16.  Foreign Assets Control Regulations, Etc.  Neither the sale
of the Notes by the Company hereunder nor its use of the proceeds thereof will
violate the Trading with the Enemy Act, as amended, or any of the foreign assets
control regulations of the United States Treasury Department (31 CFR, Subtitle
B, Chapter V, as amended) or any enabling legislation or executive order
relating thereto.

     Section 5.17.  Status under Certain Statutes.  Neither the Company nor any
Restricted Subsidiary is an "investment company" registered or required to be
registered subject to regulation under the Investment Company Act of 1940, as
amended, or is subject to regulation under the Public Utility Holding Company
Act of 1935, as amended, or the Federal Power Act, as amended.

this Agreement and the Notes rank at least pari passu in right of payment with
all other senior unsecured Indebtedness (actual or contingent) of the Company,
including, without limitation, all senior unsecured Indebtedness of the Company
described in SCHEDULE 5.15 hereto.

     Section 5.19.  Environmental Matters.  Neither the Company nor any
Subsidiary has knowledge of any claim or has received any notice of any claim,
and no proceeding has been instituted raising any claim against the Company or
any of its Subsidiaries or any of their respective real properties now or
formerly owned, leased or operated by any of them or other assets, alleging any
damage to the environment or violation of any Environmental Laws, except, in
each case, such as could not reasonably be expected to result in a Material
Adverse Effect. Except as otherwise disclosed to you in writing:

            (a) neither the Company nor any Subsidiary has knowledge of any
     facts which would give rise to any claim, public or private, of violation
     of Environmental Laws or damage to the environment emanating from,
     occurring on or in any way related to real properties now or formerly
     owned, leased or operated by any of them or to other assets or their use,

     Section 6.1.  Purchase for Investment.  You represent that you are
purchasing the Notes for your own account or for one or more separate accounts
maintained by you or for the account of one or more pension or trust funds and
not with a view to the distribution thereof; provided that the disposition of
your or their property shall at all times be within your or their control. You
understand that the Notes have not been registered under the Securities Act and
may be resold only if registered pursuant to the provisions of the Securities
Act or if an exemption from registration is available, except under
circumstances where neither such registration nor such an exemption is required
by law, and that the Company is not required to register the Notes.

     Section 6.2.  Source of Funds.  You represent that at least one of the
following statements is an accurate representation as to each source of funds (a
"Source") to be used by you to pay the purchase price of the Notes to be

     meaning of Department of Labor Prohibited Transaction Exemption ("PTE") 95-
     60 (issued July 12, 1995) and there is no employee benefit plan, treating
     as a single plan all plans maintained by the same employer or employee
     organization, with respect to which the amount of the general account
     reserves and liabilities for all contracts held by or on behalf of such
     plan exceed ten percent (10%) of the total reserves and liabilities of such
     general account (exclusive of separate account liabilities) plus surplus,
     as set forth in the NAIC Annual Statement filed with your state of
     domicile; or

            (b) the Source is either (i) an insurance company pooled separate
     account, within the meaning of PTE 90-1 (issued January 29, 1990), or (ii)
     a bank collective investment fund, within the meaning of PTE 91-38 (issued
     July 12, 1991) and, except as you have disclosed to the Company in writing
     pursuant to this paragraph (b), no employee benefit plan or group of plans
     maintained by the same employer or employee organization beneficially owns
     more than 10% of all assets allocated to such pooled separate account or
     collective investment fund; or

            (c) the Source constitutes assets of an "investment fund" (within
     the meaning of Part V of the QPAM Exemption) managed by a "qualified
     professional asset manager" or "QPAM" (within the meaning of Part V of the
     QPAM Exemption), no employee benefit plan's assets that are included in
     such investment fund, when combined with the assets of all other employee
     benefit plans established or maintained by the same employer or by an
     affiliate (within the meaning of Section V(c)(1) of the QPAM Exemption) of
     such employer or by the same employee organization and managed by 

                                     -12-
<PAGE>
 
     such QPAM, exceed 20% of the total client assets managed by such QPAM, the
     conditions of Part l(c) and (g) of the QPAM Exemption are satisfied,
     neither the QPAM nor a Person controlling or controlled by the QPAM
     (applying the definition of "control" in Section V(e) of the QPAM
     Exemption) owns a 5% or more interest in the Company and (i) the identity
     of such QPAM and (ii) the names of all employee benefit plans whose assets
     are included in such investment fund have been disclosed to the Company in
     writing pursuant to this paragraph (c); or

            (d) the Source is a governmental plan; or

            (e) the Source is one or more employee benefit plans, or a separate
     account or trust fund comprised of one or more employee benefit plans, each
     of which has been identified to the Company in writing pursuant to this
     paragraph (e); or

            (f) the Source is an insurance company separate account maintained
     solely in connection with the fixed contractual obligations of the
     insurance company under which the amounts payable, or credited, to an
     employee benefit plan (or its related trust) and to any participant or
     beneficiary of such plan (including any annuitant) are not affected in any
     manner by the investment performance of the separate account; or

            (g) the Source does not include assets of any employee benefit plan,
     other than a plan exempt from the coverage of ERISA.

     If you or any subsequent transferee of the Notes indicates that you or such
transferee are relying on any representation contained in paragraph (b), (c) or
(e) above, the Company shall deliver on the date of Closing and, if it is
legally able to do so, on the date of any applicable transfer a certificate,
which shall either state that (i) it is neither a party in interest nor a
"disqualified person" (as defined in Section 4975(e)(2) of the Code), with
respect to any plan identified pursuant to paragraphs (b) or (e) above, or (ii)
with respect to any plan identified pursuant to paragraph (c) above, neither it
nor any "affiliate" (as defined in Section V(c) of the QPAM Exemption) has at
such time, and during the immediately preceding one year, exercised the
authority to appoint or terminate said QPAM as manager of any plan identified in
writing pursuant to paragraph (c) above or to negotiate the terms of said QPAM's
management agreement on behalf of any such identified plan.  As used in this
SECTION 6.2, the terms "employee benefit plan", "governmental plan", "party in
interest" and "separate account" shall have the respective meanings assigned to
such terms in Section 3 of ERISA.

from time to time any part of, the Notes, in an amount not less than 2% of the
aggregate principal amount of the Notes then outstanding in the case of a
partial prepayment, at 100% of the principal amount so prepaid, together with
interest accrued thereon to the date of such prepayment, plus the Make-Whole
Amount determined for the prepayment date (which shall be a Business Day) with
respect to such principal amount. The Company will give each holder of Notes
written notice of each optional prepayment under this SECTION 8.2 not less than
30 days and not more than 60 days prior to the date fixed for such prepayment.
Each such notice shall specify such date, the aggregate principal amount of the
Notes to be prepaid on such date, the principal amount of each Note held by such
holder to be prepaid (determined in accordance with SECTION 8.4), and the
interest to be paid on the prepayment date with respect to such principal amount
being prepaid, and shall be accompanied by a certificate of a Senior Financial
Officer as to the estimated Make-Whole Amount due in connection with such
prepayment (calculated as if the date of such notice were the date of the
prepayment), setting forth the details of such computation. Two Business Days
prior to such prepayment, the Company shall deliver to each holder of Notes a
certificate of a Senior Financial Officer specifying the calculation of such
Make-Whole Amount as of the specified prepayment date.

     Section 8.3.  Change in Control.  (a) Notice of Change in Control or
Control Event. The Company will, within five Business Days after any Responsible
Officer has knowledge of the occurrence of any Change in Control or Control
Event, give written notice of such Change in Control or Control Event to each
holder of Notes unless notice in respect of such Change in Control (or the
Change in Control contemplated by such Control Event) shall have been given
pursuant to subparagraph (b) of this Section. If a Change in Control has
occurred, such notice shall contain and constitute an offer to prepay Notes as
described in subparagraph (c) of this Section and shall be accompanied by the
certificate described in subparagraph (g) of this Section.

       (b) Condition to Company Action.  The Company will not take any action
that consummates or finalizes a Change in Control unless (i) at least 30 days
prior to such action it shall have given to each holder of Notes written notice
containing and constituting an offer to prepay Notes as described in
subparagraph (c) of this Section, accompanied by the certificate described in
subparagraph (g) of this Section, and (ii) contemporaneously with such action,
it prepays all Notes required to be prepaid in accordance with this Section.

                                     -19-

       (c) Offer to Prepay Notes.  The offer to prepay Notes contemplated by
subparagraphs (a) and (b) of this Section shall be an offer to prepay, in
accordance with and subject to this Section, all, but not less than all, the
Notes held by each holder (in this case only, "holder" in respect of any Note
registered in the name of a nominee for a disclosed beneficial owner shall mean
such beneficial owner) on a date specified in such offer (the "Proposed
Prepayment Date").  If such Proposed Prepayment Date is in connection with an
offer contemplated by subparagraph (a) of this Section, such date shall be not
less than 30 days and not more than 120 days after the date of such offer (if
the Proposed Prepayment Date shall not be specified in such offer, the Proposed
Prepayment Date shall be the first Business Day after the 45th day after the
date of such offer).

       (d) Acceptance.  A holder of Notes may accept the offer to prepay made
pursuant to this Section by causing a notice of such acceptance to be delivered
to the Company not later than 15 days after receipt by such holder of the most
recent offer of prepayment.  A failure by a holder of Notes to respond to an
offer to prepay made pursuant to this Section shall be deemed to constitute a
rejection of such offer by such holder.

       (e) Prepayment.  Prepayment of the Notes to be prepaid pursuant to this
Section shall be at 100% of the principal amount of such Notes, together with
interest on such Notes accrued to the date of prepayment, but without Make-Whole
Amount or other premium.  The prepayment shall be made on the Proposed
Prepayment Date except as provided in subparagraph (f) of this Section.

       (f) Deferral Pending Change in Control.  The obligation of the Company to
prepay Notes pursuant to the offers required by subparagraph (c) and accepted in
accordance with subparagraph (d) of this Section is subject to the occurrence of
the Change in Control in respect of which such offers and acceptances shall have
been made.  In the event that such Change in Control has not occurred on the
Proposed Prepayment Date in respect thereof, the prepayment shall be deferred
until, and shall be made on, the date on which such Change in Control occurs.
The Company shall keep each holder of Notes reasonably and timely informed of
(i) any such deferral of the date of prepayment, (ii) the date on which such
Change in Control and the prepayment are expected to occur, and (iii) any
determination by the Company that efforts to effect such Change in Control have
ceased or been abandoned (in which case the offers and acceptances made pursuant
to this Section in respect of such Change in Control shall be deemed rescinded).

       (g) Officer's Certificate.  Each offer to prepay the Notes pursuant to
this Section shall be accompanied by a certificate, executed by a Senior
Financial Officer of the Company and dated the date of such offer, specifying:
(i) the Proposed Prepayment Date; (ii) that such offer is made pursuant to this
SECTION 8.3; (iii) the principal amount of each Note offered to be prepaid; 

                                     -20-
<PAGE>
 
(iv) the interest that would be due on each Note offered to be prepaid, accrued
to the Proposed Prepayment Date; (v) that the conditions of this Section have
been fulfilled; and (vi) in reasonable detail, the nature and date or proposed
date of the Change in Control.

       (h) Certain Definitions.  "Change in Control" shall be deemed to have
occurred if any person (as such term is used in Section 13(d) and Section
14(d)(2) of the Exchange Act as in effect on the date of the Closing) or related
persons constituting a group (as such term is used in Rule 13d-5 under the
Exchange Act), other than the Colburn Control Group,


            (i)   become the "beneficial owners" (as such term is used in Rule
       13d-3 under the Exchange Act as in effect on the date of the Closing),
       directly or indirectly, of more than 50% of the total voting power of all
       classes then outstanding of the Company's voting stock, or

            (ii)  acquire after the date of the Closing (x) the power to elect,
       appoint or cause the election or appointment of at least a majority of
       the members of the board of directors of the Company, through beneficial
       ownership of the capital stock of the Company or otherwise, or (y) all or
       substantially all of the properties and assets of the Company.

       "Control Event" means:

            (i)   the execution by the Company or any of its Subsidiaries or
       Affiliates of any agreement or letter of intent with respect to any
       proposed transaction or event or series of transactions or events which,
       individually or in the aggregate, may reasonably be expected to result in
       a Change in Control,

            (ii)  the execution of any written agreement which, when fully
       performed by the parties thereto, would result in a Change in Control, or

            (iii) the making of any written offer by any person (as such term is
       used in Section 13(d) and Section 14(d)(2) of the Exchange Act as in
       effect on the date of the Closing) or related persons constituting a
       group (as such term is used in Rule 13d-5 under the Exchange Act as in
       effect on the date of the Closing) to the holders of the common stock of
       the Company, which offer, if accepted by the requisite number of holders,
       would result in a Change in Control.

     "Colburn Control Group" shall mean, collectively, any or all of:  (a)
Richard D. Colburn, (b) any spouse and lineal descendants of Richard D. Colburn,
(c) the estate of one or more of the Persons named in clauses (a) or (b) above,
(d) each trust in respect of which one or

     (i) All calculations contemplated in this SECTION 8.3 involving the capital
stock of any Person shall be made with the assumption that all convertible
Securities of such Person then outstanding and all convertible Securities
issuable upon the exercise of any warrants, options and other rights outstanding
at such time were converted at such time and that all options, warrants and
similar rights to acquire shares of capital stock of such Person were exercised
at such time.

     Section 8.4.  Allocation of Partial Prepayments.  In the case of each
partial prepayment of the Notes pursuant to SECTION 8.2, the principal amount of
the Notes to be prepaid shall be allocated among all of the Notes of all Series
at the time outstanding in proportion, as nearly as practicable, to the
respective unpaid principal amounts thereof not theretofore called for
prepayment. All prepayments made pursuant to SECTION 8.3 or SECTION 10.5 shall
be applied only to the Notes of the holders who have elected to participate in
such prepayment.

     Section 8.5.  Maturity; Surrender, Etc.  In the case of each prepayment of
Notes pursuant to this SECTION 8, the principal amount of each Note to be
prepaid shall mature and become due and payable on the date fixed for such
prepayment, together with interest on such principal amount accrued to such date
and the applicable Make-Whole Amount, if any. From and after such date, unless
the Company shall fail to pay such principal amount when so due and payable,
together with the interest and Make-Whole Amount, if any, as aforesaid, interest
on such principal amount shall cease to accrue. Any Note paid or prepaid in full
shall be surrendered to the Company and cancelled and shall not be reissued, and
no Note shall be issued in lieu of any prepaid principal amount of any Note.

     Section 8.6.  Purchase of Notes.  The Company will not and will not permit
any Affiliate to purchase, redeem, prepay or otherwise acquire, directly or
indirectly, any of the outstanding Notes except upon the payment or prepayment
of the Notes in accordance with the terms of this Agreement and the Notes. The
Company will promptly cancel all Notes acquired by it or any Affiliate pursuant
to any payment, prepayment or purchase of Notes pursuant to any provision of
this Agreement and no Notes may be issued in substitution or exchange for any
such Notes.

     Section 8.7.  Make-Whole Amount.  The term "Make-Whole Amount" means, with
respect to any Note, an amount equal to the excess, if any, of the Discounted
Value of the Remaining Scheduled Payments with respect to the Called Principal
of such Note over the amount of such Called Principal; provided that the Make-
Whole Amount may in no event be less 

                                     -22-
<PAGE>
 
than zero. For the purposes of determining the Make-Whole Amount, the following
terms have the following meanings:

          "Called Principal" means, with respect to any Note, the principal of
     such Note that is to be prepaid pursuant to SECTION 8.2 or has become or is
     declared to be immediately due and payable pursuant to SECTION 12.1, as the
     context requires.

          "Discounted Value" means, with respect to the Called Principal of any
     Note, the amount obtained by discounting all Remaining Scheduled Payments
     with respect to such Called Principal from their respective scheduled due
     dates to the Settlement Date with respect to such Called Principal, in
     accordance with accepted financial practice and at a discount factor
     (applied on the same periodic basis as that on which interest on the Notes
     is payable) equal to the Reinvestment Yield with respect to such Called
     Principal.

          "Reinvestment Yield" means, with respect to the Called Principal of
     any Note, 0.50% over the yield to maturity implied by (a) the yields
     reported, as of 10:00 A.M. (New York City time) on the second Business Day
     preceding the Settlement Date with respect to such Called Principal, on the
     display designated as "Page PX1" or other appropriate page of the Bloomberg
     Financial Markets Services Screen (or such other display as may replace
     Page PX1 or other appropriate page on the Bloomberg Financial Markets
     Services Screen) for actively traded U.S. Treasury securities having a
     maturity equal to the Remaining Average Life of such Called Principal as of
     such Settlement Date, or (b) if such yields are not reported as of such
     time or the yields reported as of such time are not ascertainable
     (including by way of interpolation), the Treasury Constant Maturity Series
     Yields reported, for the latest day for which such yields have been so
     reported as of the second Business Day preceding the Settlement Date with
     respect to such Called Principal, in Federal Reserve Statistical Release
     H.15 (519) (or any comparable successor publication) for actively traded
     U.S. Treasury securities having a constant maturity equal to the Remaining
     Average Life of such Called Principal as of such Settlement Date.  Such
     implied yield will be determined, if necessary, by (i) converting U.S.
     Treasury bill quotations to bond-equivalent yields in accordance with
     accepted financial practice and (ii) interpolating linearly between (1) the
     actively traded U.S. Treasury security with the average life closest to and
     greater than the Remaining Average Life and (2) the actively traded U.S.
     Treasury security with the average life closest to and less than the
     Remaining Average Life.

          "Remaining Average Life" means, with respect to any Called Principal,
     the number of years (calculated to the nearest day) obtained by dividing
     (a) such Called Principal into (b) the sum of the products obtained by
     multiplying (i) the principal component of each Remaining Scheduled Payment
     with respect to such Called Principal 

                                     -23-
<PAGE>
 
     by (ii) the number of years (calculated to the nearest day) that will
     elapse between the Settlement Date with respect to such Called Principal
     and the scheduled due date of such Remaining Scheduled Payment.

          "Remaining Scheduled Payments" means, with respect to the Called
     Principal of any Note, all payments of such Called Principal and interest
     thereon that would be due after the Settlement Date with respect to such
     Called Principal if no payment of such Called Principal were made prior to
     its scheduled due date; provided that if such Settlement Date is not a date
     on which interest payments are due to be made under the terms of the Notes,
     then the amount of the next succeeding scheduled interest payment will be
     reduced by the amount of interest accrued to such Settlement Date and
     required to be paid on such Settlement Date pursuant to SECTION 8.2 or
     12.1.

          "Settlement Date" means, with respect to the Called Principal of any
     Note, the date on which such Called Principal is to be prepaid pursuant to
     SECTION 8.2 or has become or is declared to be immediately due and payable
     pursuant to SECTION 12.1, as the context requires.

Section 9.  Affirmative Covenants.

     The Company covenants that so long as any of the Notes are outstanding:

     Section 9.1.  Compliance with Law.  The Company will, and will cause each
of its Subsidiaries to, comply with all laws, ordinances or governmental rules
or regulations to which each of them is subject, including, without limitation,
ERISA and all Environmental Laws, and will obtain and maintain in effect all
licenses, certificates, permits, franchises and other governmental
authorizations necessary to the ownership of their respective properties or to
the conduct of their respective businesses, in each case to the extent necessary
to ensure that non-compliance with such laws, ordinances or governmental rules
or regulations or failures to obtain or maintain in effect such licenses,
certificates, permits, franchises and other governmental authorizations could
not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.

                                     -24-
<PAGE>
 
              Section 9.3. Maintenance of Properties. The Company will, and will
cause each of its Restricted Subsidiaries to, maintain and keep, or cause to be
maintained and kept, their respective properties in good repair, working order
and condition (other than ordinary wear and tear), so that the business carried
on in connection therewith may be properly conducted at all times; provided that
this Section shall not prevent the Company or any Restricted Subsidiary from
discontinuing the operation and the maintenance of any of its properties if such
discontinuance is desirable in the conduct of its business and the Company has
concluded that such discontinuance could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect.

              Section 9.4. Payment of Taxes and Claims. The Company will, and
will cause each of its Subsidiaries to, file all tax returns required to be
filed in any jurisdiction and to pay and discharge all taxes shown to be due and
payable on such returns and all other taxes, assessments, governmental charges,
or levies imposed on them or any of their properties, assets, income or
franchises, to the extent such taxes and assessments have become due and payable
and before they have become delinquent and all claims for which sums have become
due and payable that have or might become a Lien on properties or assets of the
Company or any Subsidiary; provided that neither the Company nor any Subsidiary
need pay any such tax or assessment or claims if (a) the amount, applicability
or validity thereof is contested by the Company or such Subsidiary on a timely
basis in good faith and in appropriate proceedings, and the Company or a
Subsidiary has established adequate reserves therefor in accordance with GAAP on
the books of the Company or such Subsidiary or (b) the nonpayment of all such
taxes and assessments and claims in the aggregate could not reasonably be
expected to have a Material Adverse Effect.

              Section 9.5. Corporate Existence, Etc. Subject to SECTION 10.5,
the Company will at all times preserve and keep in full force and effect its
corporate existence. Subject to SECTION 10.5, the Company will at all times
preserve and keep in full force and effect the corporate existence of each of
its Restricted Subsidiaries (unless merged into the Company or a Restricted
Subsidiary) and all rights and franchises of the Company and its Restricted
Subsidiaries unless, in the good faith judgment of the Company, the termination
of or failure to preserve and keep in full force and effect such corporate
existence, right or franchise could not, individually or in the aggregate, have
a Material Adverse Effect.

              Section 9.6. Nature of Business. Neither the Company nor any
Restricted Subsidiary will engage in any business if, as a result, the general
nature of the business (as described in the Memorandum), taken on a consolidated
basis, which would then be engaged in by the Company and its Restricted
Subsidiaries would be substantially changed from the general nature of the
business engaged in by the Company and its Restricted Subsidiaries on the date
of this Agreement.
                                     -25-

              Section 9.7. Notes to Rank Pari Passu. The Notes are and at all
times shall remain direct and unsecured obligations of the Company ranking pari
passu as against the assets of the Company with all other Notes from time to
time issued and outstanding hereunder without any preference among themselves
and pari passu with all other present and future unsecured Indebtedness (actual
or contingent) of the Company which is not expressed to be subordinate or junior
in rank to any other unsecured Indebtedness of the Company.


Section 10.  Negative Covenants.


              The Company covenants that so long as any of the Notes are
              outstanding:

times keep and maintain Consolidated Net Worth at an amount not less than the

Capital Stock computed on a cumulative basis for each of the elapsed fiscal
quarters ending after December 31, 1997.

quarters to Consolidated Fixed Charges for such fiscal period at not less than
1.50 to 1.00.

              Section 10.3.  Limitations on Indebtedness. (a) The Company will
not, and will not permit any Restricted Subsidiary to, create, assume, guarantee
or otherwise incur or in any manner become liable in respect of any
Indebtedness, except:


            (1) Indebtedness evidenced by the Notes;

            (2) Indebtedness of a Restricted Subsidiary to the Company or to a

     Restricted Subsidiaries, provided that at the time of creation, issuance,
     assumption, guarantee or incurrence thereof and after giving effect thereto
     and to the application of the proceeds thereof (i) the ratio of
     Consolidated Indebtedness to Consolidated Net Worth would not exceed 2.5 to

     Indebtedness then outstanding shall not exceed 25% of Consolidated Net
     Worth.
                                     -26-

amount remaining unpaid at the time of such renewal, extension or refunding,
provided that (i) at the time of any such renewal, extension or refunding and
after giving effect thereto, no Default or Event of Default would exist and (ii)
any renewal, extension or refunding of the Notes shall be accomplished in
accordance with the applicable provisions of this Agreement.  It is understood
and agreed that this provision shall not in any way create any obligation on the
part of any holder to consent to, or consider a request for, any extension,
renewal or refunding.


       (c) Any Person which becomes a Restricted Subsidiary after the date
hereof shall for all purposes of this SECTION 10.3 be deemed to have created,

Subsidiary.


       Section 10.4. Limitation on Liens. The Company will not, and will not
permit any Restricted Subsidiary to, create or incur, or suffer to be incurred
or to exist, any Lien on its or their property or assets, whether now owned or
hereafter acquired, or upon any income or profits therefrom, or transfer any

     Restricted Subsidiary shall be the surviving or continuing corporation and

     corporation if,

                  (i) the surviving or continuing corporation is the Company;
            provided that at the time of such consolidation or merger and

               the laws of the United States of America or any state thereof or
               the District of Columbia, (y) shall have executed and delivered

               covenants in the Notes, this Agreement and the Other Agreements
               to be performed or observed by the Company and an opinion of
               counsel reasonably satisfactory to such holders to the effect
               that the instrument of assumption has been duly authorized,
               executed and delivered and constitutes the legal, valid and
               binding contract and agreement of the surviving corporation
               enforceable in accordance with its terms, except as enforcement
               of such terms may be limited by bankruptcy, insolvency,

               enforcement of creditors' rights generally and by general
               equitable principles, and at the time of such consolidation or

       (b)     The Company will not, and will not permit any Restricted
Subsidiary to, sell, lease (as lessor), transfer, abandon or otherwise dispose
of assets (except assets (including, without limitation, rental equipment
inventory) sold in the ordinary course of business for fair market value) to any
Person; provided that the foregoing restrictions do not apply to:


               (1) the sale, lease, transfer or other disposition of assets of
     the Company to a Wholly-owned Restricted Subsidiary or of a Restricted
     Subsidiary to the Company or a Wholly-owned Restricted Subsidiary;

               (2) the sale of accounts receivable for fair market value,
     without recourse to the Company or any Restricted Subsidiary, to a bank or
     other financial institution or to the Company or any Wholly-owned
     Restricted Subsidiary or to any other Person in a transaction involving a
     bank or other financial institution; or

               (3) the sale of assets for cash or other property to a Person or
     Persons (other than an Affiliate) if all of the following conditions are
     met:

                  (i) such assets (valued at net book value) do not, together
          with all other assets of the Company and its Restricted Subsidiaries
          previously disposed of during the immediately preceding 12 calendar
          month period (other than in the ordinary course of business or as
          provided in (1) or (2) above), exceed 10% of 

                                     -30-
<PAGE>
 
          Consolidated Total Assets, determined as of the end of the immediately
          preceding fiscal year;

                  (ii)   in the opinion of a Responsible Officer of the Company,
          the sale is for fair value and is in the best interests of the
          Company; and

                  (iii)  immediately after the consummation of the transaction
          and after giving effect thereto, no Default or Event of Default would
          exist;


     provided, however, that for purposes of the foregoing calculation, there
     shall not be included any assets the proceeds of which were or are applied
     within one year of the date of sale of such assets to either (A) the
     acquisition of fixed assets or other property (including, without
     limitation, rental equipment inventory) useful and intended to be used in
     the operation of the business of the Company and its Restricted
     Subsidiaries as described in SECTION 9.6 hereof or (B) the prepayment at
     100% of the principal amount thereof, together with interest accrued to the
     date of such prepayment, but without Make-Whole Amount or other premium, on
     a pro rata basis, of Senior Funded Indebtedness of the Company.  It is
     understood and agreed by the Company that:  (A) any holder of the Notes may
     decline any such offer of prepayment, (B) the failure of any such holder to
     accept or decline any such offer of prepayment shall be deemed to be an
     election by such holder to decline such prepayment, and (C) if such offer
     is so accepted, the proceeds so offered towards the prepayment of the Notes
     and accepted shall be prepaid.  In the event any holder of Senior Funded
     Indebtedness of the Company declines any such offer of prepayment, the
     Company shall offer, on a pro rata basis, the proceeds so declined to the
     holders of Senior Funded Indebtedness of the Company accepting the offer of
     prepayment.  To the extent such holders of Senior Funded Indebtedness shall
     decline such payments, the Company and its Restricted Subsidiaries may use
     the remaining amount of such declined proceeds for general corporate
     purposes and such declined proceeds shall be deemed to have been applied to
     the prepayment of Senior Funded Indebtedness for the purpose of the
     immediately preceding proviso.  If and to the extent the Senior Funded
     Indebtedness being prepaid shall be with respect to a revolving credit or
     similar credit facility providing the Company with the right to obtain
     loans or other extensions of credit from time to time, such amount being so
     applied shall permanently reduce the availability of credit under such
     credit facility by an amount not less than the amount of such proceeds so
     applied to the prepayment of such Indebtedness.


     Computations pursuant to this SECTION 10.5(B) shall include dispositions
made pursuant to SECTION 10.5(c) and computations pursuant to SECTION 10.5(c)
shall include dispositions made pursuant to this SECTION 10.5(b).

       (c) The Company will not, and will not permit any Restricted Subsidiary
to, sell, pledge or otherwise dispose of any shares of the stock (including as
"stock" for the purposes of this SECTION 10.5(C) any options or warrants to
purchase stock or other Securities exchangeable for or convertible into stock)
of a Restricted Subsidiary (said stock, options, warrants and other Securities
herein called "Subsidiary Stock") or any Indebtedness of any Restricted
Subsidiary, nor will any Restricted Subsidiary issue, sell, pledge or otherwise
dispose of any shares of its own Subsidiary Stock to any Person, provided that
the foregoing restrictions do not apply to:


            (1) the issue of directors' qualifying shares; or

            (2) the issue of Subsidiary Stock to the Company or a Wholly-owned
     Restricted Subsidiary; or

            (3) the sale or other disposition at any one time to a Person (other
     than directly or indirectly to an Affiliate) of the entire Investment of
     the Company and its other Restricted Subsidiaries in any Restricted
     Subsidiary if all of the following conditions are met:


                  (i)   the assets (valued at net book value) of such Restricted
            Subsidiary do not, together with all other assets of the Company and
            its Restricted Subsidiaries previously disposed of during the
            immediately preceding 12 calendar month period (other than in the
            ordinary course of business or as provided in (1) or (2) above),
            exceed 10% of Consolidated Total Assets, determined as of the end of
            the immediately preceding fiscal year;

                  (ii)  in the opinion of a Responsible Officer of the Company,
            the sale is for fair value and is in the best interests of the
            Company;

                  (iii) immediately after the consummation of the transaction
            and after giving effect thereto, such Restricted Subsidiary shall
            have no Indebtedness of or continuing Investment in the capital
            stock of the Company or of any Restricted Subsidiary and any such
            Indebtedness or Investment shall have been discharged or acquired,
            as the case may be, by the Company or a Restricted Subsidiary; and

                  (iv)  immediately after the consummation of the transaction
            and after giving effect thereto, no Default or Event of Default
            would exist;


     provided, however, that for purposes of the foregoing calculation, there
     shall not be included any assets the proceeds of which were or are applied
     within one year of the date of sale of such assets to either (A) the
     acquisition of fixed assets or other property 

                                     -32-

     (including, without limitation, rental equipment inventory) useful and
     intended to be used in the operation of the business of the Company and its
     Restricted Subsidiaries as described in SECTION 9.6 or (B) the prepayment
     at 100% of the principal amount thereof, together with interest accrued to
     the date of such prepayment, but without Make-Whole Amount or other
     premium, on a pro rata basis, of Senior Funded Indebtedness of the Company.
     It is understood and agreed by the Company that: (A) any holder of the
     Notes may decline any such offer of prepayment, (B) the failure of any such
     holder to accept or decline any such offer of prepayment shall be deemed to
     be an election by such holder to decline such prepayment, and (C) if such
     offer is so accepted, the proceeds so offered towards the prepayment of the
     Notes and accepted shall be prepaid. In the event any holder of Senior
     Funded Indebtedness of the Company declines any such offer of prepayment,
     the Company shall offer, on a pro rata basis, the proceeds so declined to
     the holders of Senior Funded Indebtedness of the Company accepting the
     offer of prepayment. To the extent such holders of Senior Funded
     Indebtedness shall decline such payments, the Company and its Restricted
     Subsidiaries may use the remaining amount of such declined proceeds for
     general corporate purposes and such declined proceeds shall be deemed to
     have been applied to the prepayment of Senior Funded Indebtedness for the
     purpose of the immediately preceding proviso. If and to the extent the
     Senior Funded Indebtedness being prepaid shall be with respect to a
     revolving credit or similar credit facility providing the Company with the
     right to obtain loans or other extensions of credit from time to time, such
     amount being so applied shall permanently reduce the availability of credit
     under such credit facility by an amount not less than the amount of such
     proceeds so applied to the prepayment of such Indebtedness.


     Computations pursuant to this SECTION 10.5(C) shall include dispositions
made pursuant to SECTION 10.5(B) and computations pursuant to SECTION 10.5(B)
shall include dispositions made pursuant to this SECTION 10.5(C).


     Section 10.6.  Transactions with Affiliates. The Company will not, and will
not permit any Restricted Subsidiary to, enter into or be a party to any
Material transaction or Material group of related transactions with any
Affiliate, other than the Company or a Restricted Subsidiary (including, without
limitation, the purchase from, sale to or exchange of property with, or the
rendering of any service by or for, any Affiliate), except in the ordinary
course of and pursuant to the reasonable requirements of the Company's or such
Restricted Subsidiary's business and upon fair and reasonable terms no less
favorable to the Company or such Restricted Subsidiary than would obtain in a
comparable arm's-length transaction with a Person other than an Affiliate.

Section 12.  Remedies on Default, Etc.


     Section 12.1. Acceleration. (a) If an Event of Default with respect to the
Company described in paragraph (g) or (h) of SECTION 11 (other than an Event of
Default described in clause (i) of paragraph (g) or described in clause (vi) of
paragraph (g) by virtue of the fact that such clause encompasses clause (i) of
paragraph (g)) has occurred, all the Notes then outstanding shall automatically
become immediately due and payable.


     (b) If any other Event of Default has occurred and is continuing, any
holder or holders of more than 51% in principal amount of the Notes at the time
outstanding may at any time at its or their option, by notice or notices to the
Company, declare all the Notes then outstanding to be immediately due and
payable.

     (c) If any Event of Default described in paragraph (a) or (b) of SECTION
11 has occurred and is continuing, any holder or holders of Notes at the time
outstanding affected by such Event of Default may at any time, at its or their
option, by notice or notices to the Company, declare all the Notes held by it or
them to be immediately due and payable.


     Upon any Note's becoming due and payable under this SECTION 12.1, whether
automatically or by declaration, such Note will forthwith mature and the entire
unpaid principal amount of such Note, plus (i) all accrued and unpaid interest
thereon and (ii) the Make-Whole 

                                     -36-
<PAGE>
 
Amount determined in respect of such principal amount (to the full extent
permitted by applicable law), shall all be immediately due and payable, in each
and every case without presentment, demand, protest or further notice, all of
which are hereby waived. The Company acknowledges, and the parties hereto agree,
that each holder of a Note has the right to maintain its investment in the Notes
free from repayment by the Company (except as herein specifically provided for),
and that the provision for payment of a Make-Whole Amount by the Company in the
event that the Notes are prepaid or are accelerated as a result of an Event of
Default, is intended to provide compensation for the deprivation of such right
under such circumstances.


              Section 12.2. Other Remedies. If any Default or Event of Default
has occurred and is continuing, and irrespective of whether any Notes have
become or have been declared immediately due and payable under SECTION 12.1, the
holder of any Note at the time outstanding may proceed to protect and enforce
the rights of such holder by an action at law, suit in equity or other
appropriate proceeding, whether for the specific performance of any agreement
contained herein or in any Note, or for an injunction against a violation of any
of the terms hereof or thereof, or in aid of the exercise of any power granted
hereby or thereby or by law or otherwise.

              Section 12.3. Rescission. At any time after any Notes have been
declared due and payable pursuant to clause (b) or (c) of SECTION 12.1, the
holders of not less than 66 2/3% in principal amount of the Notes then
outstanding, by written notice to the Company, may rescind and annul any such
declaration and its consequences if (a) the Company has paid all overdue
interest on the Notes, all principal of and Make-Whole Amount, if any, on any
Notes that are due and payable and are unpaid other than by reason of such
declaration, and all interest on such overdue principal and Make-Whole Amount,
if any, and (to the extent permitted by applicable law) any overdue interest in
respect of the Notes, at the Default Rate, (b) all Events of Default and
Defaults, other than non-payment of amounts that have become due solely by
reason of such declaration, have been cured or have been waived pursuant to
SECTION 17, and (c) no judgment or decree has been entered for the payment of
any monies due pursuant hereto or to the Notes. No rescission and annulment
under this SECTION 12.3 will extend to or affect any subsequent Event of Default
or Default or impair any right consequent thereon.

              Section 12.4. No Waivers or Election of Remedies, Expenses, Etc.
No course of dealing and no delay on the part of any holder of any Note in
exercising any right, power or remedy shall operate as a waiver thereof or
otherwise prejudice such holder's rights, powers or remedies. No right, power or
remedy conferred by this Agreement or by any Note upon any holder thereof shall
be exclusive of any other right, power or remedy referred to herein or therein
or now or hereafter available at law, in equity, by statute or otherwise.
Without limiting the obligations of the Company under SECTION 15, the Company
will pay to the holder of each Note on demand such further amount as shall be
sufficient to cover all costs and expenses of such

holder incurred in any enforcement or collection under this SECTION 12,
including, without limitation, reasonable attorneys' fees, expenses and
disbursements.


Section 13.  Registration; Exchange; Substitution of Notes.


              Section 13.1. Registration of Notes. The Company shall keep at its
principal executive office a register for the registration and registration of
transfers of Notes. The name and address of each holder of one or more Notes,
each transfer thereof and the name and address of each transferee of one or more
Notes shall be registered in such register. Prior to due presentment for
registration of transfer, the Person in whose name any Note shall be registered
shall be deemed and treated as the owner and holder thereof for all purposes
hereof, and the Company shall not be affected by any notice or knowledge to the
contrary. The Company shall give to any holder of a Note that is an
Institutional Investor promptly upon request therefor, a complete and correct
copy of the names and addresses of all registered holders of Notes.

              Section 13.2. Transfer and Exchange of Notes. Upon surrender of
any Note at the principal executive office of the Company for registration of
transfer or exchange (and in the case of a surrender for registration of
transfer, duly endorsed or accompanied by a written instrument of transfer duly
executed by the registered holder of such Note or its attorney duly authorized
in writing and accompanied by the address for notices of each transferee of such
Note or part thereof), the Company shall execute and deliver, at the Company's
expense (except as provided below), one or more new Notes (as requested by the
holder thereof) in exchange therefor, in an aggregate principal amount equal to
the unpaid principal amount of, and of the same Series as, the surrendered Note.
Each such new Note shall be payable to such Person as such holder may request
and shall be substantially in the form of EXHIBIT 1. Each such new Note shall be
dated and bear interest from the date to which interest shall have been paid on
the surrendered Note or dated the date of the surrendered Note if no interest
shall have been paid thereon. The Company may require payment of a sum
sufficient to cover any stamp tax or governmental charge imposed in respect of
any such transfer of Notes. Notes shall not be transferred in denominations of
less than $500,000; provided that if necessary to enable the registration of
transfer by a holder of its entire holding of Notes, one Note may be in a
denomination of less than $500,000. Any transferee, by its acceptance of a Note
registered in its name (or the name of its nominee), shall be deemed to have
made the representation set forth in SECTION 6.2; provided that the Company
shall not be required to effect such transfer if the Company is legally unable
to deliver the certificate described in the last paragraph of SECTION 6.2.

              Section 13.3. Replacement of Notes. Upon receipt by the Company of
evidence reasonably satisfactory to it of the ownership of and the loss, theft,
destruction or mutilation of 

                                     -38-
<PAGE>
 
any Note (which evidence shall be, in the case of an Institutional Investor,
notice from such Institutional Investor of such ownership and such loss, theft,
destruction or mutilation), and

            (a) in the case of loss, theft or destruction, of indemnity
     reasonably satisfactory to it (provided that if the holder of such Note is,
     or is a nominee for, an original Purchaser or another holder of a Note with
     a minimum net worth of at least $50,000,000, such Person's own unsecured
     agreement of indemnity shall be deemed to be satisfactory), or

            (b) in the case of mutilation, upon surrender and cancellation
     thereof,


the Company at its own expense shall execute and deliver, in lieu thereof, a new
Note, dated and bearing interest from the date to which interest shall have been
paid on, and of the same Series as, such lost, stolen, destroyed or mutilated
Note or dated the date of such lost, stolen, destroyed or mutilated Note if no
interest shall have been paid thereon.


Section 14.  Payments on Notes.


       Section 14.1.  Place of Payment. Subject to SECTION 14.2, payments
of principal, Make-Whole Amount, if any, and interest becoming due and payable
on the Notes shall be made in Modesto, California at the principal office of the
Company in such jurisdiction. The Company may at any time, by notice to each
holder of a Note, change the place of payment of the Notes so long as such place
of payment shall be either the principal office of the Company in such
jurisdiction or the principal office of a bank or trust company in such
jurisdiction.

       Section 14.2. Home Office Payment. So long as you or your nominee shall
be the holder of any Note, and notwithstanding anything contained in SECTION
14.1 or in such Note to the contrary, the Company will pay all sums becoming due
on such Note for principal, Make-Whole Amount, if any, and interest by the
method and at the address specified for such purpose below your name in SCHEDULE
A, or by such other method or at such other address as you shall have from time
to time specified to the Company in writing for such purpose, without the
presentation or surrender of such Note or the making of any notation thereon,
except that upon written request of the Company made concurrently with or
reasonably promptly after payment or prepayment in full of any Note, you shall
surrender such Note for cancellation, reasonably promptly after any such
request, to the Company at its principal executive office or at the place of
payment most recently designated by the Company pursuant to SECTION 14.1. Prior
to any sale or other disposition of any Note held by you or your nominee you
will, at your election, either endorse thereon the amount of principal paid
thereon and the last date to which interest has been paid thereon or surrender
such Note to the Company in exchange for a new Note or Notes pursuant to SECTION
13.2. The Company will afford the benefits of this SECTION 14.2 to any

                                     -39-

Institutional Investor that is the direct or indirect transferee of any Note

relating to such Note as you have made in this SECTION 14.2.


Section 15.  Expenses, Etc.

             Section 15.1. Transaction Expenses. Whether or not the
transactions contemplated hereby are consummated, the Company will pay all costs
and expenses (including reasonable attorneys' fees of a special counsel and, if
reasonably required, local or other counsel) incurred by you and each Other
Purchaser or holder of a Note in connection with such transactions and in
connection with any amendments, waivers or consents under or in respect of this
Agreement or the Notes (whether or not such amendment, waiver or consent becomes
effective), including, without limitation: (a) the costs and expenses incurred
in enforcing or defending (or determining whether or how to enforce or defend)
any rights under this Agreement or the Notes or in responding to any subpoena or
other legal process or informal investigative demand issued in connection with
this Agreement or the Notes, or by reason of being a holder of any Note, and (b)
the costs and expenses, including financial advisors' fees, incurred in
connection with the insolvency or bankruptcy of the Company or any Subsidiary or
in connection with any work-out or restructuring of the transactions
contemplated hereby and by the Notes. The Company will pay, and will save you
and each other holder of a Note harmless from, all claims in respect of any
fees, costs or expenses, if any, of brokers and finders (other than those
retained by you).

             Section 15.2. Survival. The obligations of the Company under this
SECTION 15 will survive the payment or transfer of any Note, the enforcement,
amendment or waiver of any provision of this Agreement or the Notes, and the
termination of this Agreement.


Section 16.  Survival of Representations and Warranties; Entire Agreement.


     All representations and warranties contained herein shall survive the
execution and delivery of this Agreement and the Notes, the purchase or transfer
by you of any Note or portion thereof or interest therein and the payment of any
Note, and may be relied upon by any subsequent holder of a Note, regardless of
any investigation made at any time by or on behalf of you or any other holder of
a Note.  All statements contained in any certificate or other instrument
delivered by or on behalf of the Company pursuant to this Agreement shall be
deemed representations and warranties of the Company under this Agreement.
Subject to the preceding sentence, this Agreement and the Notes embody the
entire agreement and understanding between you and the Company and supersede all
prior agreements and understandings relating to the subject matter hereof.

Section 17.  Amendment and Waiver.


              Section 17.1.  Requirements. This Agreement and the Notes may be
amended, and the observance of any term hereof or of the Notes may be waived
(either retroactively or prospectively), with (and only with) the written
consent of the Company and the Required Holders, except that (a) no amendment or
waiver of any of the provisions of SECTION 1, 2, 3, 4, 5, 6 or 21 hereof, or any
defined term (as it is used therein), will be effective as to you unless
consented to by you in writing, and (b) no such amendment or waiver may, without
the written consent of the holder of each Note at the time outstanding affected
thereby, (i) subject to the provisions of SECTION 12 relating to acceleration or
rescission, change the amount or time of any prepayment or payment of principal
of, or change the rate or change the time of payment or method of computation of
interest or of the Make-Whole Amount on, the Notes, (ii) change the percentage
of the principal amount of the Notes the holders of which are required to
consent to any such amendment or waiver, or (iii) amend any of SECTIONS 8,
11(A), 11(B), 12, 17 or 20.


              Section 17.2.  Solicitation of Holders of Notes.


       (a) Solicitation.  The Company will provide each holder of the Notes
(irrespective of the amount of Notes then owned by it) with sufficient
information, sufficiently far in advance of the date a decision is required, to
enable such holder to make an informed and considered decision with respect to
any proposed amendment, waiver or consent in respect of any of the provisions
hereof or of the Notes.  The Company will deliver executed or true and correct
copies of each amendment, waiver or consent effected pursuant to the provisions
of this SECTION 17 to each holder of outstanding Notes promptly following the
date on which it is executed and delivered by, or receives the consent or
approval of, the requisite holders of Notes.

       (b) Payment.  The Company will not directly or indirectly pay or cause to
be paid any remuneration, whether by way of supplemental or additional interest,
fee or otherwise, or grant any security, to any holder of Notes as consideration
for or as an inducement to the entering into by any holder of Notes of any
waiver or amendment of any of the terms and provisions hereof unless such
remuneration is concurrently paid, or security is concurrently granted, on the
same terms, ratably to each holder of Notes then outstanding even if such holder
did not consent to such waiver or amendment.


              Section 17.3. Binding Effect, Etc. Any amendment or waiver
consented to as provided in this SECTION 17 applies equally to all holders of
Notes and is binding upon them and upon each future holder of any Note and upon
the Company without regard to whether such Note has been marked to indicate such
amendment or waiver. No such amendment or waiver will extend to or affect any
obligation, covenant, agreement, Default or Event of Default not expressly
amended or waived or impair any right consequent thereon. No course of dealing
between the Company and

                                     -41-
<PAGE>
 
the holder of any Note nor any delay in exercising any rights hereunder or under
any Note shall operate as a waiver of any rights of any holder of such Note. As
used herein, the term "this Agreement" and references thereto shall mean this
Agreement as it may from time to time be amended or supplemented.

              Section 17.4. Notes Held by Company, Etc. Solely for the purpose
of determining whether the holders of the requisite percentage of the aggregate
principal amount of Notes then outstanding approved or consented to any
amendment, waiver or consent to be given under this Agreement or the Notes, or
have directed the taking of any action provided herein or in the Notes to be
taken upon the direction of the holders of a specified percentage of the
aggregate principal amount of Notes then outstanding, Notes directly or
indirectly owned by the Company or any of its Affiliates shall be deemed not to
be outstanding.


Section 18.  Notices.

     All notices and communications provided for hereunder shall be in writing
and sent (a) by telefacsimile if the sender on the same day sends a confirming
copy of such notice by a recognized overnight delivery service (charges
prepaid), or (b) by registered or certified mail with return receipt requested
(postage prepaid), or (c) by a recognized overnight delivery service (with
charges prepaid).  Any such notice must be sent:

            (i)    if to you or your nominee, to you or it at the address
     specified for such communications in SCHEDULE A, or at such other address
     as you or it shall have specified to the Company in writing,

            (ii)   if to any other holder of any Note, to such holder at such
     address as such other holder shall have specified to the Company in
     writing, or

            (iii)  if to the Company, to the Company at its address set forth at
     the beginning hereof (or by telefacsimile to 209-544-6756) to the attention
     of Chief Financial Officer, or at such other address as the Company shall
     have specified to the holder of each Note in writing.


Notices under this SECTION 18 will be deemed given only when actually received.


Section 19.  Reproduction of Documents.

limitation, (a) consents, waivers and modifications that may hereafter be
executed, (b) documents received by you at the Closing (except the Notes

                                     -42-
<PAGE>
 
other information previously or hereafter furnished to you, may be reproduced by
you by any photographic, photostatic, microfilm, microcard, miniature
photographic or other similar process and you may destroy any original document
so reproduced. The Company agrees and stipulates that, to the extent permitted
by applicable law, any such reproduction shall be admissible in evidence as the
original itself in any judicial or administrative proceeding (whether or not the
original is in existence and whether or not such reproduction was made by you in
the regular course of business) and any enlargement, facsimile or further
reproduction of such reproduction shall likewise be admissible in evidence. This
SECTION 19 shall not prohibit the Company or any other holder of Notes from
contesting any such reproduction to the same extent that it could contest the
original, or from introducing evidence to demonstrate the inaccuracy of any such
reproduction.


Section 20.  Confidential Information.


     For the purposes of this SECTION 20, "Confidential Information" means
information delivered to you by or on behalf of the Company or any Subsidiary in
connection with the transactions contemplated by or otherwise pursuant to this
Agreement that is proprietary in nature and that was clearly marked or labeled
or otherwise adequately identified in writing when received by you as being
confidential information of the Company or such Subsidiary; provided that such
term does not include information that (a) was publicly known or otherwise known
to you prior to the time of such disclosure, (b) subsequently becomes publicly
known through no act or omission by you or any Person acting on your behalf, (c)
otherwise becomes known to you other than through disclosure by the Company or
any Subsidiary or (d) constitutes financial statements delivered to you under
SECTION 7.1 that are otherwise publicly available.  You will maintain the
confidentiality of such Confidential Information  in accordance with procedures
adopted by you in good faith to protect confidential information of third
parties delivered to you; provided that you may deliver or disclose Confidential
Information to (i) your directors, trustees, officers, employees, agents,
attorneys and affiliates (to the extent such disclosure reasonably relates to
the administration of the investment represented by your Notes), (ii) your
financial advisors and other professional advisors who agree to hold
confidential the Confidential Information substantially in accordance with the
terms of this SECTION 20, (iii) any other holder of any Note, (iv) any
Institutional Investor to which you sell or offer to sell such Note or any part
thereof or any participation therein (if such Person has agreed in writing prior
to its receipt of such Confidential Information to be bound by the provisions of
this SECTION 20), (v) any Person from which you offer to purchase any security
of the Company (if such Person has agreed in writing prior to its receipt of
such Confidential Information to be bound by the provisions of this SECTION 20),
(vi) any federal or state regulatory authority having jurisdiction over you,
(vii) the National Association of Insurance Commissioners or any similar
organization, or any nationally recognized rating agency that requires access to
information about your investment portfolio or (viii) any other Person to which
such delivery or disclosure may be necessary or appropriate 

                                     -43-
<PAGE>
 
(w) to effect compliance with any law, rule, regulation or order applicable to
you, (x) in response to any subpoena or other legal process, (y) in connection
with any litigation to which you are a party or (z) if an Event of Default has
occurred and is continuing, to the extent you may reasonably determine such
delivery and disclosure to be necessary or appropriate in the enforcement or for
the protection of the rights and remedies under your Notes and this Agreement.
Each holder of a Note, by its acceptance of a Note, will be deemed to have
agreed to be bound by and to be entitled to the benefits of this SECTION 20 as
though it were a party to this Agreement. On reasonable request by the Company
in connection with the delivery to any holder of a Note of information required
to be delivered to such holder under this Agreement or requested by such holder
(other than a holder that is a party to this Agreement or its nominee), such
holder will enter into an agreement with the Company embodying the provisions of
this SECTION 20.


Section 21.  Substitution of Purchaser.


     You shall have the right to substitute any one of your Affiliates as the
purchaser of the Notes that you have agreed to purchase hereunder, by written
notice to the Company, which notice shall be signed by both you and such
Affiliate, shall contain such Affiliate's agreement to be bound by this
Agreement and shall contain a confirmation by such Affiliate of the accuracy
with respect to it of the representations set forth in SECTION 6.  Upon receipt
of such notice, wherever the word "you" is used in this Agreement (other than in
this SECTION 21), such word shall be deemed to refer to such Affiliate in lieu
of you.  In the event that such Affiliate is so substituted as a purchaser
hereunder and such Affiliate thereafter transfers to you all of the Notes then
held by such Affiliate, upon receipt by the Company of notice of such transfer,
wherever the word "you" is used in this Agreement (other than in this SECTION
21), such word shall no longer be deemed to refer to such Affiliate, but shall
refer to you, and you shall have all the rights of an original holder of the
Notes under this Agreement.


Section 22.  Miscellaneous.


              Section 22.1. Successors and Assigns. All covenants and other
agreements contained in this Agreement by or on behalf of any of the parties
hereto bind and inure to the benefit of their respective successors and assigns
(including, without limitation, any subsequent holder of a Note) whether so
expressed or not.

              Section 22.2. Payments Due on Non-Business Days. Anything in this
Agreement or the Notes to the contrary notwithstanding, any payment of principal
of or Make-Whole Amount or interest on any Note that is due on a date other than
a Business Day shall be made on the next succeeding Business Day without
including the additional days elapsed in the computation of the interest payable
on such next succeeding Business Day.

                                     -44-
<PAGE>
 
              Section 22.3. Severability. Any provision of this Agreement that
is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall (to the full
extent permitted by law) not invalidate or render unenforceable such provision
in any other jurisdiction.

              Section 22.4. Construction. Each covenant contained herein shall
be construed (absent express provision to the contrary) as being independent of
each other covenant contained herein, so that compliance with any one covenant
shall not (absent such an express contrary provision) be deemed to excuse
compliance with any other covenant. Where any provision herein refers to action
to be taken by any Person, or which such Person is prohibited from taking, such
provision shall be applicable whether such action is taken directly or
indirectly by such Person.

              Section 22.5. Counterparts. This Agreement may be executed in any
number of counterparts, each of which shall be an original but all of which
together shall constitute one instrument. Each counterpart may consist of a
number of copies hereof, each signed by less than all, but together signed by
all, of the parties hereto.

              Section 22.6. Governing Law. THIS AGREEMENT SHALL BE CONSTRUED AND
ENFORCED IN ACCORDANCE WITH, AND THE RIGHTS OF THE PARTIES SHALL BE GOVERNED BY,
THE LAW OF THE STATE OF NEW YORK, EXCLUDING CHOICE-OF-LAW PRINCIPLES OF THE LAW
OF SUCH STATE THAT WOULD REQUIRE THE APPLICATION OF THE LAWS OF A JURISDICTION
OTHER THAN SUCH STATE.
