                      UNION TEXAS PETROLEUM HOLDINGS, INC.
                         NOTES TO FINANCIAL STATEMENTS
                (DOLLARS IN THOUSANDS EXCEPT PER SHARE AMOUNTS)

NOTE 1 - BASIS OF PRESENTATION - These consolidated financial statements should
be read in the context of the consolidated financial statements and notes
thereto filed with the Commission in the Company's 1994 annual report on Form
10-K.  In the opinion of management, the accompanying unaudited consolidated
financial statements reflect all adjustments, consisting only of normal
adjustments, necessary to present fairly the financial position of Union Texas
Petroleum Holdings, Inc. and its consolidated subsidiaries at March 31, 1995,
and the results of operations and cash flows for the three months ended March
31, 1995 and 1994.  The results of operations for the three months ended March
31, 1995, should not necessarily be taken as indicative of the results of
operations that may be expected for the entire year 1995.

NOTE 2 - RECENT DEVELOPMENTS - Since May 1994, the Company had an effective
shelf registration statement on file with the Commission covering up to $200
million of its debt securities.  In March 1995, the Company publicly issued
$125 million principal amount of 8-3/8% Senior Notes due 2005 (the "8-3/8%
Senior Notes") at an initial public offering price of 99.431%.  In April 1995,
the Company publicly issued $75 million principal amount of 8-1/2% Senior Notes
due 2007 (the "8-1/2% Senior Notes" together with the 8-3/8% Senior Notes
referred to as the "Senior Notes") at an initial public offering price of
99.658%.  The net proceeds from the sale of the 8-3/8% Senior Notes and the
8-1/2% Senior Notes were approximately $123.3 million and $74.1 million,
respectively (after deducting underwriting discount, commissions and offering
expenses).  The Company used such proceeds to reduce debt under the $350
million credit facility and its uncommitted and unsecured lines of credit.  The
Senior Notes represent general unsecured obligations of the Company and rank
pari passu in right of payment with the Company's obligations under its credit
facilities, its 8.25% Senior Notes due 1999 and senior in right of payment to
all subordinated indebtedness of the Company.  The Senior Notes are guaranteed
by the subsidiaries of the Company that are also guarantors under the Company's
credit facilities and outstanding $100 million principal amount of senior notes
due 1999 and contain restrictive covenants similar to the Company's senior
notes due 1999.  The Senior Notes are redeemable at any time, at the option of
the Company, in whole or in part, at a price equal to 100% of their principal
amount plus accrued interest plus a make whole premium relating to the
then-prevailing Treasury Yield and the remaining life of the Senior Notes.

NOTE 3 - ACCOUNTING PRONOUNCEMENTS RECENTLY ISSUED - In March 1995, the
Financial Accounting Standards Board ("FASB") released Statement of Financial
Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to Be Disposed Of," which set forth the
criteria for impairment of plant, property and equipment and other long-lived
assets.  Adoption of the Statement is required for years beginning after
December 15, 1995.  The Company is still reviewing the Statement; however, the
Company believes its current policy on oil and gas asset impairment is
consistent with this pronouncement and that the pronouncement will have no
material impact on the Company.


NOTE 4 - CONTINGENCIES - The Company and its subsidiaries and related companies
are named defendants in a number of lawsuits and named parties in numerous
government proceedings arising in the ordinary course of business.  While the
outcome of contingencies, lawsuits or other proceedings against the Company
cannot be predicted with certainty, management expects that any liability, to
the extent not provided for through insurance or otherwise, will not have a
material adverse effect on the financial statements of the Company.

                      UNION TEXAS PETROLEUM HOLDINGS, INC.

With respect to the unaudited consolidated financial information of Union Texas
Petroleum Holdings, Inc. for the three- month periods ended March 31, 1995 and
1994, Price Waterhouse LLP reported that they have applied limited procedures
in accordance with professional standards for a review of such information.
However, their separate report dated April 20, 1995 appearing below, states
that they did not audit and they do not express an opinion on that unaudited
consolidated financial information.  Price Waterhouse LLP has not carried out
any significant or additional audit tests beyond those which would have been
necessary if their report had not been included.  Accordingly, the degree of
reliance on their report on such information should be restricted in light of
the limited nature of the review procedures applied.  Price Waterhouse LLP is
not subject to the liability provisions of section 11 of the Securities Act of
1933 for their report on the unaudited consolidated financial information
because that report is not a "report" prepared or certified by Price Waterhouse
LLP within the meaning of sections 7 and 11 of the Act.


                  REPORT ON REVIEW BY INDEPENDENT ACCOUNTANTS


To the Board of Directors
of Union Texas Petroleum Holdings, Inc.



We have reviewed the accompanying consolidated balance sheet of Union Texas
Petroleum Holdings, Inc. and consolidated subsidiaries as of March 31, 1995 and
the related consolidated statements of operations and of cash flows for the
three-month periods ended March 31, 1995 and 1994.  This financial information
is the responsibility of the Company's management.

We conducted our review in accordance with standards established by the
American Institute of Certified Public Accountants.  A review of interim
financial information consists principally of applying analytical review
procedures to financial data and making inquiries of persons responsible for
financial and accounting matters.  It is substantially less in scope than an
audit conducted in accordance with generally accepted auditing standards, the
objective of which is the expression of an opinion regarding the financial
statements taken as a whole.  Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the accompanying financial information for it to be in conformity
with generally accepted accounting principles.

We previously audited in accordance with generally accepted auditing standards,
the consolidated balance sheet as of December 31, 1994, and the related
consolidated statements of operations, of cash flows, and of stockholders'
equity for the year then ended (not presented herein), and in our report dated
January 25, 1995 we expressed an unqualified opinion on those consolidated
financial statements.  In our opinion, the information set forth in the
accompanying consolidated balance sheet information as of December 31, 1994, is
fairly stated in all material respects in relation to the consolidated balance
sheet from which it has been derived.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

The following discussion should be read in conjunction with the financial
statements, notes, and management's discussion contained in the registrant's
1994 annual report on Form 10-K, and condensed financial statements and notes
contained in this report.


RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 1995 COMPARED WITH THREE MONTHS ENDED MARCH 31,
1994

Net income for the three months ended March 31, 1995, was $47 million, or $.53
per share as compared to net income of $27 million, or $.30 per share reported
for the same period in 1994.   The current quarter was favorably impacted by
higher U.S. ethylene margins and sales volumes and higher international oil and
gas prices partially offset by lower Indonesian LNG volumes.

Sales and operating revenues for the three months ended March 31, 1995, were
$240 million, up from $194 million for the first quarter of 1994.
International revenues totaled $184 million as compared to $163 million for the
first quarter of 1994.  In the U.K., sales and operating revenues increased by
$20 million due to higher crude prices and increased sales volumes.  In
Indonesia, sales were $1 million below 1994 as higher crude oil and LNG prices
were offset by lower LNG volumes, attributable to the contracted cargo mix
which resulted in a lower average participation interest in cargoes delivered
for the quarter.  It is not expected that these lower LNG volumes will be made
up during the remainder of 1995.   In Pakistan, sales were $2 million above
1994 primarily due to higher crude oil and natural gas prices.

Average prices received and volumes sold by the Company's major operations
during the first quarter of 1995 and 1994, respectively, were as follows:

</TABLE>

Petrochemical revenues totaled $55 million as compared to $31 million in the
first quarter of 1994, while operating profit was $19 million as compared to $1
million in the prior period.  The increase was primarily due to higher ethylene
sales prices which resulted in an increase in ethylene margins to 16 cents per
pound in 1995 vs. 1 cent per pound in 1994 and due to higher volumes.

Exploration expenses increased by $3 million reflecting the Company's expanded
1995 exploration program.  Interest expense increased by $4 million during the
period due to higher levels of debt, primarily due to the funding of the
Britannia acquisition during the fourth quarter of 1994 and higher interest
rates.  The effective tax rate decreased from the prior year due primarily to
the increase in U.S. petrochemical income, which is taxed at lower rates.

FINANCIAL CONDITION

Cash flow from operations:  Net cash provided by operating activities was $61
million in the first quarter of 1995, an increase of $14 million from the same
period in the prior year.  The improvement was primarily the result of improved
ethylene margins and sales volumes and higher international oil and gas
prices, partially offset by lower Indonesian LNG volumes.

Ethylene margins have averaged approximately 16 cents per pound in the first
quarter of 1995.  The Company cannot predict the duration of the recent
favorable trends in the ethylene business.  The ethylene business is cyclical
and there can be no assurances that margins will remain at their current levels
over the near term.  The prices the Company receives for its ethylene are
sensitive to many factors beyond the control of the Company, such as worldwide
and U.S. demand for petrochemicals, inventory levels, feedstock costs and
availability, plant utilization rates, plant operations and costs and
competitive capacity expansion.

Capital resources:  Capital expenditures for the first quarter of 1995 were $39
million including capitalized interest of $5 million. Capital expenditures for
the first quarter of 1994 were $29 million including capitalized interest of $6
million.  The current quarter increase was principally due to development costs
for the Britannia field and increased exploration spending.

Financing activities:  During 1994, the Company replaced its $650 million
unsecured revolving credit facility with three unsecured credit facilities (the
"Credit Facilities").  One of the Credit Facilities was a $100 million
unsecured credit agreement with NationsBank of Texas, N.A. ("NationsBank"), as
agent, Bank of America National Trust and Savings Association ("Bank of
America") and Union Bank of Switzerland, Houston Agency ("UBS"), as co-agents.
This Credit Facility was a revolver that provided for conversion of amounts
outstanding on September 15, 1995 to a one-year term loan maturing September
15, 1996.  The Company has terminated this Credit Facility effective March 31,
1995 as a result of the issuance of the new senior notes discussed below.  The
Company's other two Credit Facilities are with NationsBank, as agent, Bank of
America, and UBS, as co-agents, and certain other banks.  One of these Credit
Facilities is a $350 million revolver that reduces quarterly by $25 million
beginning July 31, 1997 and has a final maturity of April 30, 1998.  The other
Credit Facility is a $200 million revolver that provides for conversion of
outstanding amounts on April 30, 1995 to a one-year term loan maturing April
30, 1996.  The Company has negotiated amendments to extend the maturities and
certain terms on the latter two Credit Facilities, subject to execution of
definitive agreements.  Borrowings under the Credit Facilities are guaranteed
by certain subsidiaries of the Company that also guarantee the Company's senior
notes.  The Credit Facilities contain restrictive covenants, including
limitations on incurrence of additional indebtedness, asset sales and mergers
or consolidations.  The Credit Facilities restrict the amount of total
indebtedness incurred by the Company and the restricted subsidiaries referred
to in the Credit Facilities, which include the guarantors and certain other
subsidiaries ("Restricted Subsidiaries"), to $750 million of senior
indebtedness (including the aggregate $300 million principal amount of senior
notes described below and amounts drawn under the Credit Facilities) and $100
million of subordinated indebtedness.  Debt of unrestricted subsidiaries and
nonrecourse debt on certain assets of the Company and its subsidiaries are not
limited under the Credit Facilities, subject to certain conditions.  The sum of
the senior notes and the commitments under the Credit Facilities equals $850
million.  As a result, the Company is currently unable to fully utilize the
Commitments under the Credit Facilities.  However, the Company is pursuing an
amendment to the restriction on total indebtedness under the Credit Facilities.
At March 31, 1995, $207 million was outstanding under the Credit Facilities
bearing interest at a weighted average rate of 6.8% per annum, and
approximately $250 million was available for additional borrowings under such
existing Credit Facilities.





                                       7
<PAGE>   9
At March 31, 1995, $71 million was outstanding under the Company's uncommitted
and unsecured lines of credit.  These amounts outstanding bear interest at a
weighted average rate of 6.9% per annum and are included in the total
indebtedness restriction under the Company's Credit Facilities and reduce
amounts available under the Company's Credit Facilities.  

Since May 1994, the Company had an effective shelf registration statement on
file with the Commission covering up to $200 million of its debt securities.  In
March 1995, the Company publicly issued $125 million principal amount of 8-3/8%
Senior Notes due 2005 (the "8-3/8% Senior Notes") at an initial public offering
price of 99.431%.  In April 1995, the Company publicly issued $75 million
principal amount of 8-1/2% Senior Notes due 2007 (the "8-1/2% Senior Notes"
together with the 8-3/8% Senior Notes referred to as the "Senior Notes") at an
initial public offering price of 99.658%.  The net proceeds from the sale of the
8-3/8% Senior Notes and the 8-1/2% Senior Notes were approximately $123.3
million and $74.1 million, respectively (after deducting underwriting discount,
commissions and offering expenses).  The Company used such proceeds to reduce
debt under the $350 million Credit Facility and its uncommitted and unsecured
lines of credit. The Senior Notes represent general unsecured obligations of the
Company and rank pari passu in right of payment with the Company's obligations
under its Credit Facilities, its 8.25% Senior Notes due 1999 and senior in right
of payment to all subordinated indebtedness of the Company.  The Senior Notes
are guaranteed by the subsidiaries of the Company that are also guarantors under
the Company's Credit Facilities and outstanding $100 million principal amount of
senior notes due 1999 and contain restrictive covenants similar to the Company's
senior notes due 1999.  The Senior Notes are redeemable at any time, at the
option of the Company, in whole or in part, at a price equal to 100% of their
principal amount plus accrued interest plus a make whole premium relating to the
then-prevailing Treasury Yield and the remaining life of the Senior Notes. 

On April 27, 1994, the Company's Board of Directors authorized the repurchase of
up to 2,000,000 shares of the Company's common stock and pursuant thereto, the
Company had repurchased 307,500 shares as of December 31, 1994. The repurchased
stock will be used for general corporate purposes, including fulfilling employee
benefit program obligations.  No repurchases were made by the Company during the
first quarter of 1995.  As of March 31, 1995, 163,135 shares of common stock
were held, at cost, as treasury shares.

Financial condition:  In the first quarter of 1995, the Company declared and
paid a dividend of approximately $4.4 million on its common stock.  On April
13, 1995, the Company announced a dividend on its common stock of $.05 per
share to stockholders of record as of April 28, 1995, payable on May 15, 1995.

In March 1995, the Financial Accounting Standards Board ("FASB") released
Statement of Financial Accounting Standards No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of,"
which set forth the criteria for impairment of plant, property and equipment
and other long-lived assets.  Adoption of the Statement is required for years
beginning after December 15, 1995.  The Company is still reviewing the
Statement; however, the Company believes its current policy on oil and gas
asset impairment is consistent with this pronouncement and that the
pronouncement will have no material impact on the Company.

                          PART II - OTHER INFORMATION

ITEM 1 - LEGAL PROCEEDINGS

The Company and its subsidiaries and related companies are named defendants in
numerous lawsuits and named parties in numerous governmental proceedings
arising in the ordinary course of business.  While the outcome of lawsuits or
other proceedings against the Company cannot be predicted with certainty,
management does not expect these matters to have a material adverse effect on
the financial statements of the Company.  (See Item 3 in the Company's 1994
annual report on Form 10-K.)

ITEM 5 - OTHER INFORMATION

Eastern Indonesia.  In April 1995,  the Company entered into an agreement to
transfer to Canadian Occidental Petroleum Ltd. ("CanOxy") a 26-2/3% working
interest in two production sharing contracts covering acreage in the Maluku
(Moluccas) Island group in the Banda Sea of Eastern Indonesia, subject to
approval of Pertamina, the Indonesian national oil company.  The Company will
retain a 33-1/3% working interest in the two production sharing contracts.  The
Company also granted CanOxy an option until September 30, 1995, to acquire a
26-2/3% working interest in two remaining production sharing contracts covering
acreage in the same area, which, if exercised, would reduce the Company's
working interest in such production sharing contracts to 33-1/3%.  Drilling of
an initial exploration well is expected to commence in mid-1995.

Pakistan. In April 1995, the Company signed a concession agreement with the
Government of Pakistan covering approximately 1.8 million acres in the Eastern
Sindh block in the Sindh Province of southeastern Pakistan for which the
Company was granted an exploration license in December 1994.  The concession
agreement and the exploration license provide the Company the right to explore
for oil and gas, and upon a commercial discovery, the right to apply for a 20-
year lease from the Pakistan government.  The Company is the operator and has a
70% working interest in the concession and exploration license, which is
subject to reduction if the Pakistan government elects to participate upon
discovery of commercial production.  The Company plans to conduct seismic
activities in the Eastern Sindh concession area during late 1995.

Secondary Public Offering.  Following a request by the KKR Partnerships, the
Company has filed a registration statement for 10 million of their 33.3 million
shares of the Company's common stock (the "Common Stock Offering").  All shares
will be sold by the KKR Partnerships.  The KKR Partnerships have granted the
underwriters an option to purchase up to an additional 1.5 million shares to
cover over-allotments, if any.  The Company will not receive any proceeds from
the Common Stock Offering.  Pursuant to the terms of the registration rights
agreement, the Company will pay the expenses of the Common Stock Offering
estimated to be approximately $700 thousand.

                        DEFINITIONS AND OTHER PROVISIONS
                             OF GENERAL APPLICATION
 
     SECTION 101. Definitions.
 
     For all purposes of this Indenture, except as otherwise expressly provided
or unless the context otherwise requires:
 
          (1) the terms defined in this Article have the meanings assigned to
     them in this Article and include the plural as well as the singular;
 
          (2) all accounting terms not otherwise defined herein have the

     provided, the term "generally accepted accounting principles" with respect
     to any computation required or permitted hereunder shall mean such
     accounting principles as are generally accepted in the United States at the
     date of such computation; and
 
          (3) the words "herein," "hereof" and "hereunder" and other words of

required to be made in Authorized Newspapers, the successive publications may be
made in the same or in different newspapers in the same city meeting the
foregoing requirements and in each case on any Business Day.

or other action provided by this Indenture to be given or taken by Holders may
be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Holders in person or by an agent duly appointed in writing.
If Securities of a series are issuable as Bearer Securities, any request,
demand, authorization, direction, notice, consent, waiver or other action
provided by this Indenture to be given by Holders of such series may,
alternatively, be embodied in and evidenced by the record of Holders of
Securities of such series voting in favor thereof, either in person or by
proxies duly appointed in writing, at a meeting of Holders of Securities of such
series duly called and held in accordance with the provisions of Article
Thirteen, or a combination of such instruments and any such records. Except as
herein otherwise expressly provided, such action shall become effective when
such instrument or instruments or record or both are deliverable to the Trustee
and, where it is hereby expressly required, to the Company. Such instrument or
instruments and any such record (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments and so voting at any such meeting. Proof of
execution of any such instrument or of a writing appointing any such agent, or
the holding of any Person of a Security, shall be sufficient for any purpose of
this Indenture and (subject to Section 701) conclusive in favor of the Trustee
and the Company, if made in the manner provided in this Section. The record of
any meeting of Holders of Securities shall be proved in the manner provided in
Section 1406.
 
     The Company may set in advance a record date for purposes of determining
the identity of Holders of Registered Securities entitled to vote or consent to
any action by vote or consent authorized or permitted under this Indenture,
which record date shall be the later of 30 days prior to the first solicitation
of such consent or the date of the most recent list of Holders furnished to the
Trustee prior to such solicitation. If a record date is fixed, those Persons who
were Holders of Outstanding Registered Securities at such record date (or their
duly designated proxies), and only those persons, shall be entitled with respect
to such Securities to take such action by vote or consent or to revoke any vote
or consent previously given, whether or not such Persons continue to be Holders
after such record date. Promptly after any record date is set pursuant to this
paragraph, the Company, at its own expense, shall cause notice thereof to be
given to the Trustee in writing in the manner provided in Section 106 and to the
relevant Holders as set forth in Section 107.
 
     (b) The fact and date of the execution by any Person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. Where such execution is by
a signer acting in a capacity other than his individual capacity, such
certificate or affidavit shall also constitute sufficient proof of his
authority. The fact and date of the execution of any such instrument or writing,
or the authority of the Person executing the same, may also be proved in any
other manner which the Trustee deems sufficient.
 
                                       10
<PAGE>   18
 
     (c) The principal amount and serial numbers of Registered Securities held
by any Person, and the date of holding the same, shall be proved by the Security
Register.
 
     (d) The principal amount and serial numbers of Bearer Securities held by
any Person, and the date of holding the same, may be proved by the production of
such Bearer Securities or by a certificate executed, as depositary, by any trust
company, bank, banker or other depositary, wherever situated, if such
certificate shall be deemed by the Trustee to be satisfactory, showing that at
the date therein mentioned such Person had on deposit with such depositary or
exhibited to it, the Bearer Securities therein described; or such facts may be
proved by the certificate of the Person holding such Bearer Securities, if such
certificate or affidavit is deemed by the Trustee to be satisfactory. The
Trustee and the Company may assume that such ownership of any Bearer Security
continues until (1) another certificate bearing a later date issued in respect
of the same Bearer Security is produced, (2) such Bearer Security is produced to
the Trustee by some other Person, (3) such Bearer Security is surrendered in
exchange for a Registered Security, or (4) such Bearer Security is no longer
Outstanding. The principal amount and serial numbers of Bearer Securities held
by any Person, and the date of holding the same, may also be proved in any other
manner which the Trustee deems sufficient.
 
     (e) Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Holder of any Security shall bind every future Holder of the
same Security and the Holder of every Security issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security. Any Holder or subsequent Holder may revoke the request, demand,
authorization, direction, notice, consent or other Act as to his Security or
portion of his Security; provided, however, that such revocation shall be
effective only if the Trustee receives the notice of revocation before the date
the Act becomes effective.
 
     SECTION 106. Notices, Etc., to Trustee and Company.
 
     Any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with,
 
          (1) the Trustee by any Holder or by the Company shall be sufficient
     for every purpose hereunder if made, given, furnished or filed in writing
     to or with the Trustee at its Corporate Trust Office, Attention: Corporate
     Trust Services Division or
 
          (2) the Company by the Trustee or by any Holder shall be sufficient
     for every purpose hereunder (unless otherwise herein expressly provided) if
     in writing and mailed, first-class postage prepaid, to the Company
     addressed to it (a) in the case of Registered Securities, at the address of
     its principal office specified in the first paragraph of this instrument or
     at any other address previously furnished in writing to the Trustee by the
     Company, Attention: General Counsel; and (b) in the case of Bearer
     Securities, at the address of an office or agency located outside the
     United States maintained by the Company in accordance with Section 1002.
 
     SECTION 107. Notice to Holders; Waiver.
 
     Where this Indenture provides for notice to Holders of Securities of any
event, such notice shall be sufficiently given (unless otherwise herein
expressly provided) (i) to Holders of Registered Securities if in writing and
mailed, first-class postage prepaid, to each Holder affected by such event, at
the address of such Holder as it appears in the Security Register, not later
than the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice and (ii) to Holders of Bearer Securities if published in
an Authorized Newspaper in the City of New York and London or other capital city
in Western Europe and in such other city or cities as may be specified in such
Bearer Securities on a Business Day at least twice, the first such publication
to be not earlier than the earliest date, and not later than the latest date,
prescribed for the giving of such notice.
 
     In case by reason of the suspension of regular mail service, or by reason
of any other cause it shall be impracticable to give such notice to Holders of
Registered Securities by mail, then such notification as shall be
 
                                       11
<PAGE>   19
 
made with the approval of the Trustee shall constitute a sufficient notification
for every purpose hereunder. In any case in which notice to Holders of
Registered Securities is given by mail, neither the failure to mail such notice,
nor any defect in any notice so mailed, to any particular holder of a Registered
Security, shall affect the sufficiency of such notice with respect to other
Holders of Registered Securities or the sufficiency of any notice to Holders of
Bearer Securities given as provided herein.
 
     In case by reason of the suspension of any Authorized Newspaper or
Authorized Newspapers or by reason of any other cause it shall be impracticable
to publish any notice to Holders of Bearer Securities as provided above, then
such notification to Holders of Bearer Securities as shall be made with the
approval of the Trustee for such Securities shall constitute sufficient notice
to such Holders for every purpose hereunder. Neither the failure to give notice
by publication to Holders of Bearer Securities as provided above, nor any defect
in any notice so published, shall affect the sufficiency of any notice to
Holders of Registered Securities given as provided herein.
 
     Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders shall be filed with the Trustee, but such filing
shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.
 
     SECTION 108. Conflict with Trust Indenture Act.
 
     If any provision hereof limits, qualifies or conflicts with any provision
of the Trust Indenture Act or another provision hereof which is required to be
included in this Indenture by any of the provisions of the Trust Indenture Act,
such provision of the Trust Indenture Act shall control. If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
which may be so modified or excluded, the former provision shall be deemed to
apply to this Indenture as so modified or to be excluded.
 
     SECTION 109. Effect of Headings and Table of Contents.
 
     The Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.
 
     SECTION 110. Successors and Assigns.
 
     All covenants and agreements in this Indenture by the Company shall bind
its successors and assigns, whether so expressed or not.
 
     SECTION 111. Separability Clause.
 
     In case any provision in this Indenture or in the Securities (or any coupon
appertaining thereto) shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.
 
     SECTION 112. Benefits of Indenture.
 
     Nothing in this Indenture or in the Securities (or any coupon appertaining
thereto), express or implied, shall give to any Person, other than the parties
hereto and their successors hereunder, any Authenticating Agent, Paying Agent
and Security Registrar, and the Holders, any benefit or any legal or equitable
right, remedy or claim under this Indenture.
 
     SECTION 113. Governing Law.
 
     THIS INDENTURE AND THE SECURITIES (OR ANY COUPON APPERTAINING THERETO)
SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
NEW YORK, BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW
TO THE EXTENT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE
REQUIRED THEREBY.
 
                                       12
<PAGE>   20
 
     SECTION 114. Legal Holidays.
 
     In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities
or coupons appertaining thereto) payment of principal and interest (and premium
and Additional Amounts, if any) need not be made at such Place of Payment on
such date, but may be made on the next succeeding Business Day at such Place of
Payment with the same force and effect as if made on the Interest Payment Date
or Redemption Date, or at the Stated Maturity, provided that no interest shall
accrue for the period from and after such Interest Payment Date, Redemption Date
or Stated Maturity, as the case may be.
 
     SECTION 115. Corporate Obligation.
 
     No recourse may be taken, directly or indirectly, against any incorporator,
subscriber to the capital stock, stockholder, officer, director or employee of
the Company, any Guarantor or the Trustee or of any predecessor or successor of
the Company, any Guarantor or the Trustee with respect to the Company's
obligations on the Securities or any coupons appertaining thereto or the
obligations of the Company, any Guarantor or the Trustee under this Indenture or
any certificate or other writing delivered in connection herewith. Each Holder
by accepting a Security waives all such recourse.
 
     SECTION 116. Counterpart Originals.
 
     The parties may sign any number of copies of this Indenture. Each signed
copy shall be an original, but all of them together represent the same
agreement.
 
                                  ARTICLE TWO
 
                                 SECURITY FORMS
 
     SECTION 201. Forms Generally.
 
     The Registered Securities, if any, of each series and the Bearer
Securities, if any, of each series and related coupons appertaining thereto
shall be in substantially such form or forms (including temporary or permanent
global form) as shall be established by or pursuant to a Board Resolution or in
one or more indentures supplemental hereto, in each case with such appropriate
insertions, omissions, substitutions and other variations as are required or
permitted by this Indenture and may have such letters, numbers or other marks of
identification and such legends or endorsements placed thereon as may be
required to comply with the rules of any securities exchange or as may,
consistently herewith, be determined by the officers executing such Securities
or coupons appertaining thereto, as evidenced by their execution of the
Securities or coupons appertaining thereto. If temporary Securities of any
series are issued in global form as permitted by Section 304, the form thereof
shall be established as provided in the preceding sentence. A copy of the Board
Resolution establishing the form or forms of Securities or coupons appertaining
thereto of any series (or any such temporary global Security) shall be certified
by the Secretary or an Assistant Secretary of the Company and delivered to the
Trustee at or prior to the delivery of the Company Order contemplated by Section
303 for the authentication and delivery of such Securities (or any such
temporary global Security) or coupons appertaining thereto.
 
     Unless otherwise specified as contemplated by Section 301, Bearer
Securities shall have interest coupons appertaining thereto attached.
 
     The definitive Securities and coupons appertaining thereto, if any, shall
be printed, lithographed or engraved on steel engraved borders or may be
produced in any other manner, all as determined by the officers executing such
Securities or coupons appertaining thereto, as evidenced by their execution
thereof.

<PAGE>   21
 
     SECTION 202. Form of Trustee's Certificate of Authentication.
 
     The Trustee's certificate of authentication shall be in substantially the
following form:
 
     "This is one of the Securities of the series designated therein referred to
in the within-mentioned Indenture.
 
                                          THE FIRST NATIONAL BANK OF CHICAGO
                                                        as Trustee
                                          By
                                                  Authorized Signatory".
 
     SECTION 203. Securities in Global Form.
 
     If Securities of a series are issuable in global form, as contemplated by
Section 301, then, notwithstanding clause (10) of Section 301 and the provisions
of Section 302, any such Security shall represent such of the Outstanding
Securities of such series as shall be specified therein and may provide that it
shall represent the aggregate amount of Outstanding Securities from time to time
endorsed thereon and that the aggregate amount of Outstanding Securities
represented thereby may from time to time be reduced to reflect exchanges. Any
endorsement of a Security in global form to reflect the amount, or any increase
or decrease in the amount, of Outstanding Securities represented thereby shall
be made by the Trustee in such manner and upon instructions given by such Person
or Persons as shall be specified in such Security or in a Company Order to be
delivered to the Trustee pursuant to Section 303 or Section 304. Subject to the
provisions of Section 303 and, if applicable, Section 304, the Trustee shall
deliver and redeliver any Security in permanent global form in the manner and
upon instructions given by the Person or Persons specified in such Security or
in the applicable Company Order. If a Company Order pursuant to Section 303 or
304 has been, or simultaneously is, delivered, any instructions by the Company
with respect to endorsement or delivery or redelivery of a Security in global
form shall be in writing but need not comply with Section 103 and need not be
accompanied by an Opinion of Counsel.
 
     The provisions of the last sentence of Section 303 shall apply to any
Security in global form if such Security was never issued and sold by the
Company and the Company delivers to the Trustee the Security in global form
together with written instructions (which need not comply with Section 103 and
need not be accompanied by an Opinion of Counsel) with regard to the reduction
in the principal amount of Securities represented thereby, together with the
written statement contemplated by the last sentence of Section 303.
 
     Notwithstanding the provisions of Sections 201 and 307, unless otherwise
specified as contemplated by Section 301, payment of principal of (and premium,
if any) and interest on any Security in permanent global form shall be made to
the Person or Persons specified therein.
 
     Notwithstanding the provisions of Section 308 and except as provided in the
preceding paragraph, the Company, the Trustee and any agent of the Company or of
the Trustee shall treat a Person as the Holder of such principal amount of
Outstanding Securities represented by a global Security as shall be specified in
a written statement, if any, of the Holder of such global Security or, in the
case of a global Bearer Security, of Euroclear or CEDEL S.A., which is produced
to the Security Registrar by such Holder, Euroclear or CEDEL S.A., as the case
may be.
 
     Global Securities may be issued in either registered or bearer form and in
either temporary or permanent form. Permanent global Securities will be issued
in definitive form.
 
     SECTION 204. Book-Entry Securities.
 
     Notwithstanding any provision of this Indenture to the contrary:
 
          (a) At the discretion of the Company, any Registered Security may be
     issued from time to time, in whole or in part, in permanent global form
     registered in the name of a Depositary, or its nominee. Each
 
                                       14
<PAGE>   22
 
     such Registered Security in permanent global form is hereafter referred to
     as a "Book-Entry Security". Upon such election, the Company shall execute,
     and the Trustee or an Authenticating Agent shall authenticate and deliver,
     one or more Book-Entry Securities that (i) are denominated in an amount
     equal to the aggregate principal amount of the Outstanding Securities of
     such series, (ii) are registered in the name of the Depositary or its
     nominee, (iii) are delivered by the Trustee or an Authenticating Agent to
     the Depositary or pursuant to the Depositary's instructions and (iv) bear a
     legend in substantially the following form (or such other form as the
     Depositary and the Company may agree upon):
 
        UNLESS THIS SECURITY IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF
        [THE DEPOSITARY], TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF
        TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED
        IN THE NAME OF [NOMINEE OF THE DEPOSITARY] OR IN SUCH OTHER NAME AS IS
        REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF [THE DEPOSITARY], AND ANY
        PAYMENT IS MADE TO [NOMINEE OF THE DEPOSITARY] OR TO SUCH OTHER ENTITY
        AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF [THE DEPOSITARY], ANY
        TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY
        PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, [NOMINEE OF
        THE DEPOSITARY], HAS AN INTEREST HEREIN.
 
          (b) Any Book-Entry Security shall be initially executed and delivered
     as provided in Section 303. Notwithstanding any other provision of this
     Indenture, unless and until it is exchanged in whole or in part for
     Registered Securities not issued in global form, a Book-Entry Security may
     not be transferred except as a whole by the Depositary to a nominee of such
     Depositary, by a nominee of such Depositary to such Depositary or another
     nominee of such Depositary, or by such Depositary or any such nominee to a
     successor Depositary or a nominee of such successor Depositary.
 
          (c) If at any time the Depositary notifies the Company or the Trustee
     that it is unwilling or unable to continue as Depositary for any Book-Entry
     Securities, the Company shall appoint a successor Depositary, whereupon the
     retiring Depositary shall surrender or cause the surrender of its
     Book-Entry Security or Securities to the Trustee. The Trustee shall
     promptly notify the Company upon receipt of such notice. If a successor
     Depositary has not been so appointed by the effective date of the
     resignation of the Depositary, the Book-Entry Securities will be issued as
     Registered Securities not issued in global form, in an aggregate principal
     amount equal to the principal amount of the Book-Entry Security or
     Securities theretofore held by the Depositary.
 
          The Company may at any time and in its sole discretion determine that
     the Securities shall no longer be Book-Entry Securities represented by a
     global certificate or certificates, and will so notify the Depositary. Upon
     receipt of such notice, the Depositary shall promptly surrender or cause
     the surrender of its Book-Entry Security or Securities to the Trustee.
     Concurrently therewith, Registered Securities not issued in global form
     will be issued in an aggregate principal amount equal to the principal
     amount of the Book-Entry Security or Securities theretofore held by the
     Depositary.
 
          Upon any exchange of Book-Entry Securities for Registered Securities
     not issued in global form as set forth in this Section 204(c), such
     Book-Entry Securities shall be cancelled by the Trustee, and Securities
     issued in exchange for such Book-Entry Securities pursuant to this Section
     shall be registered in such names and in such authorized denominations as
     the Depositary for such Book-Entry Securities, pursuant to instructions
     from its direct or indirect participants or otherwise, shall instruct the
     Trustee. The Trustee or any Authenticating Agent shall deliver such
     Securities to the persons in whose names such Securities are so registered.
 
          (d) The Company and the Trustee shall be entitled to treat the Person
     in whose name any Book-Entry Security is registered as the Holder thereof
     for all purposes of the Indenture and any applicable laws, notwithstanding
     any notice to the contrary received by the Trustee or the Company; and the
     Trustee and the Company shall have no responsibility for transmitting
     payments to, communication with,
 
                                       15
<PAGE>   23
 
     notifying, or otherwise dealing with any beneficial owners of any
     Book-Entry Security. Neither the Company nor the Trustee shall have any
     responsibility or obligations, legal or otherwise, to the beneficial owners
     or to any other party including the Depositary, except for the Holder of
     any Book-Entry Security, provided, however, notwithstanding anything herein
     to the contrary, (i) for the purposes of determining whether the requisite
     principal amount of Outstanding Securities have given, made or taken any
     request, demand, authorization, direction, notice, consent, waiver,
     instruction or other action hereunder as of any date, the Trustee shall
     treat any Person specified in a written statement of the Depositary with
     respect to any Book-Entry Securities as the Holder of the principal amount
     of such Securities set forth therein and (ii) nothing herein shall prevent
     the Company, the Trustee, or any agent of the Company or Trustee, from
     giving effect to any written certification, proxy or other authorization
     furnished by a Depositary with respect to any Book-Entry Securities, or
     impair, as between a Depositary and holders of beneficial interests in such
     Securities, the operation of customary practices governing the exercise of
     the rights of the Depositary as Holder of such Securities.
 
          (e) So long as any Book-Entry Security is registered in the name of a
     Depositary or its nominee, all payments of the principal of (and premium,
     if any) and interest on such Book-Entry Security and redemption thereof and
     all notices with respect to such Book-Entry Security shall be made and
     given, respectively, in the manner provided in the arrangements of the
     Company with such Depositary.

     are to be issuable initially in temporary global form and whether any
     Securities of the series are to be issuable in permanent global form, as
     Book-Entry Securities or otherwise, with or without coupons appertaining
     thereto and, if so, whether beneficial owners of interests in any such
     permanent global Security may exchange such interests for Securities of
     such series and of like tenor of any authorized form and denomination and
     the circumstances under which any such exchanges may occur, if other than
     in the manner provided in Section 305, and the Depositary for any global
     Security or Securities;
 
          (4) the manner in which, or the Person to whom, any interest on any
     Bearer Security of the series shall be payable, if otherwise than upon
     presentation and surrender of the coupons appertaining thereto as they
     severally mature and the extent to which, or the manner in which, any

     payable;
 
          (8) the period or periods within which, the price or prices (whether
     denominated in cash, securities or otherwise) at which and the terms and
     conditions upon which Securities of the series may be redeemed, in whole or
     in part, at the option of the Company, if the Company is to have that
     option, and the manner in which the Company must exercise any such option;
 
          (9) the obligation, if any, of the Company to redeem or purchase
     Securities of the series pursuant to any sinking fund or analogous
     provisions or at the option of a Holder thereof and the period or periods
     within which, the price or prices (whether denominated in cash, securities
     or otherwise) at which and the terms and conditions upon which, Securities
     of the series shall be redeemed or purchased in whole or in part pursuant
     to such obligation;
 
          (10) the denomination in which any Registered Securities of that
     series shall be issuable, if other than denominations of $1,000 and any
     integral multiple thereof, and the denomination in which any Bearer
     Securities of that series shall be issuable, if other than the denomination
     of $5,000;
 
          (11) the currency or currencies (including composite currencies) in
     which payment of the principal of (and premium, if any), any interest on
     and any Additional Amounts with respect to the Securities of the series
     shall be payable if other than the currency of the United States of
     America;
 
          (12) if the principal of (and premium, if any) or interest on the
     Securities of the series are to be payable, at the election of the Company
     or a Holder thereof, in a currency or currencies (including composite
     currencies) other than that in which the Securities are stated to be
     payable, the currency or currencies (including composite currencies) in
     which payment of the principal of (and premium, if any) and interest on,
     and any Additional Amounts with respect to, Securities of such series as to
     which such election is made shall be payable, and the periods within which
     and the terms and conditions upon which such election is to be made;
 
          (13) if the amount of payments of principal of (and premium, if any),
     any interest on and any Additional Amounts with respect to the Securities
     of the series may be determined with reference to any commodities,
     currencies or indices, or values, rates or prices, the manner in which such
     amounts shall be determined;
 
          (14) if other than the principal amount thereof, the portion of the
     principal amount of Securities of the series which shall be payable upon
     declaration of acceleration of the Maturity thereof pursuant to Section
     602;
 
          (15) any additional means of satisfaction and discharge of this
     Indenture with respect to Securities of the series pursuant to Section 501,
     any additional conditions to discharge pursuant to Section 501 or 503 and
     the application, if any, of Section 503;
 
          (16) any deletions or modifications of or additions to the Events of
     Default set forth in Section 601 or covenants of the Company set forth in
     Article Ten pertaining to the Securities of the series; and
 
          (17) any other terms of the series (which terms shall not be
     inconsistent with the provisions of this Indenture).
 
     All Securities of any one series and the coupons appertaining to any Bearer
Securities of such series shall be substantially identical except in the case of
Registered Securities, as to denomination and except as may
 
                                       17

otherwise be provided in or pursuant to the Board Resolution referred to above
and (subject to Section 303) set forth, or determined in the manner provided, in
the Officers' Certificate referred to above or in any such indenture
supplemental hereto.
 
     At the option of the Company, interest on the Registered Securities of any
series that bears interest may be paid by mailing a check to the address of any
Holder as such address shall appear in the Security Register.
 
     If any of the terms of the series are established by action taken pursuant
to a Board Resolution, a copy of an appropriate record of such action together
with such Board Resolution shall be certified by the Secretary or an Assistant
Secretary of the Company and delivered to the Trustee at or prior to the
delivery of the Officers' Certificate setting forth the terms of the series.
 
     At the direction of the Company and the Guarantors, the Securities of any
series may be guaranteed (the "Guaranteed Securities").
 
     SECTION 302. Denominations.
 
     The Securities of each series shall be issuable in such denominations as
shall be specified as contemplated by Section 301. In the absence of any such
provisions with respect to the Securities of any series, the Registered
Securities of such series denominated in Dollars shall be issuable in
denominations of $1,000 and any integral multiple thereof and any Bearer
Securities of such series denominated in Dollars shall be issuable in the
denominations of $5,000 and any integral multiple thereof. Unless otherwise
provided as contemplated by Section 301 with respect to any series of
Securities, any Securities of a series denominated in a currency other than
Dollars shall be issuable in denominations that are the equivalent, as
determined by the Company by reference to the noon buying rate in The City of
New York for cable transfers for such currency, as such rate is reported or
otherwise made available by the Federal Reserve Bank of New York, on the
applicable issue date for such Securities, of $1,000 and any integral multiple
thereof.
 
     SECTION 303. Execution, Authentication, Delivery and Dating.
 
     The Securities shall be executed on behalf of the Company by its Chairman
or one of its Vice Presidents, under its corporate seal, which may be in
facsimile form, reproduced thereon or affixed thereto and attested by its
Secretary or one of its Assistant Secretaries. The signature of any of these
officers on the Securities may be manual or facsimile. Coupons shall bear the
facsimile signature of the Chairman or any Vice President of the Company.
 
     Securities and coupons appertaining thereto bearing the manual or facsimile
signatures of individuals who were at any time the proper officers of the
Company shall bind the Company, notwithstanding that such individuals or any of
them have ceased to hold such offices prior to the authentication and delivery
of such Securities or did not hold such offices at the date of such Securities
or coupons.
 
     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series, together with any
coupons appertaining thereto, executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities as in this Indenture
provided and not otherwise; provided, however, that, in connection with its
sale, during the "restricted period" (as defined in Section
1.163-5(c)(2)(i)(D)(7) of the United States Treasury Regulations), no Bearer
Security shall be mailed or otherwise delivered to any location in the United
States; and provided, further, that a Bearer Security may (other than a
temporary global security in bearer form delivered as provided in Section 304)
be delivered outside the United States in connection with its original issuance
and only if the Person entitled to receive such Bearer Security shall have
furnished a certificate in the form set forth in Exhibit A to this Indenture, or
in such other form of certificate as shall contain information then required by
federal income tax laws and, if applicable, federal securities laws, dated no
earlier than the Certification Date. If any Security shall be represented by a
permanent global Bearer Security, then, for purposes of this Section and Section
304, the notation of a beneficial owner's interest therein upon original
issuance of such Security or upon exchange of a portion of a temporary global
Security shall be deemed to be
 
                                       18
<PAGE>   26
 
delivery in connection with sale, during the "restricted period" (as defined in
Section 1.163-5(c)(2)(i)(D)(7) of the United States Treasury Regulations) of
such beneficial owner's interest in such permanent global Security. Except as
permitted by Section 306, the Trustee shall not authenticate and deliver any
Bearer Security unless all appurtenant coupons for interest then matured have
been detached and cancelled.
 
     If the form or terms of the Securities of the series have been established
in or pursuant to one or more Board Resolutions as permitted by Sections 201 and
301, in authenticating such Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and (subject to Section 701) shall be
fully protected in relying upon, an Opinion of Counsel stating,
 
          (a) if the form of such Securities has been established by or pursuant
     to Board Resolution as permitted by Section 201, that such form has been
     established in conformity with the provisions of this Indenture;
 
          (b) if the terms of such Securities have been established by or
     pursuant to Board Resolution as permitted by Section 301, that such terms
     have been established in conformity with the provisions of this Indenture;
     and
 
          (d) that such Securities, together with any coupons appertaining
     thereto, when authenticated and delivered by the Trustee and issued by the
     Company in the manner and subject to any conditions specified in such
     Opinion of Counsel, will constitute legal, valid and binding obligations of
     the Company, enforceable in accordance with their terms, except as such
     enforcement is subject to the effect of (i) bankruptcy, insolvency,
     reorganization or other laws relating to or affecting creditors' rights and
     (ii) general principles of equity (regardless of whether such enforcement
     is considered in a proceeding in equity or at law).
 
If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.
 
     Each Registered Security shall be dated the date of its authentication; and
each Bearer Security shall be dated as of the date of issuance of the first
Bearer Security of such series to be issued.
 
     No Security or coupon or coupons appertaining thereto shall be entitled to
any benefit under this Indenture or be valid or obligatory for any purpose
unless there appears on such Security, or the Security to which such coupon
appertains, a certificate of authentication substantially in the form provided
for herein executed by the Trustee by manual signature, and such certificate
upon any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder. Notwithstanding
the foregoing, if any Security shall have been authenticated and delivered
hereunder but never issued and sold by the Company, and the Company shall
deliver such Security to the Trustee for cancellation as provided in Section 309
together with a written statement (which need not comply with Section 103 and
need not be accompanied by an Opinion of Counsel) stating that such Security has
never been issued and sold by the Company, for all purposes of this Indenture
such Security shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.
 
     SECTION 304. Temporary Securities.
 
     Pending the preparation of definitive Securities of any series, the Company
may execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued, in
registered form or, if authorized, in bearer form with one or more coupons
appertaining thereto or without coupons, and with such appropriate insertions,
omissions, substitutions and other variations as the officers executing such
Securities
 
                                       19
<PAGE>   27
 
may determine, as evidenced by their execution of such Securities. In the case
of any series issuable as Bearer Securities, such temporary Securities may be in
global form. A temporary Bearer Security shall be delivered only in compliance
with the conditions set forth in Section 303.
 
     Except in the case of temporary Securities in global form (which shall be
exchanged in accordance with the provisions of the following paragraphs), if
temporary Securities of any series are issued, the Company will cause definitive
Securities of that series to be prepared without unreasonable delay. After the
preparation of definitive Securities of such series, the temporary Securities of
such series shall be exchangeable for definitive Securities of such series upon
surrender of the temporary Securities of such series at the office or agency of
the Company in a Place of Payment for that series, without charge to the Holder.
Upon surrender for cancellation of any one or more temporary Securities of any
series (accompanied by any unmatured coupons appertaining thereto), the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a like principal amount of definitive Securities of the same series of
authorized denominations. Until so exchanged the temporary Securities of any
series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of such series; provided, however that no
Bearer Security shall be issued in exchange for a temporary Registered Security;
and provided, further, that a definitive Bearer Security (including interests in
a permanent global Security) shall be delivered in exchange for a temporary
Bearer Security only in compliance with the conditions set forth in Section 303.
 
     Any temporary global Bearer Security and any permanent global Bearer
Security shall, unless otherwise provided therein, be delivered to the London
office of a depositary or common depositary (the "Common Depositary") for the
benefit of Euroclear and CEDEL S.A. for credit to the respective accounts of the
beneficial owners of such Securities (or to such other accounts as they may
direct).
 
     Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary global
Bearer Security of a series (the "Exchange Date"), the Company shall deliver to
the Trustee definitive Securities of that series in aggregate principal amount
equal to the principal amount of such temporary global Bearer Security, executed
by the Company. On or after the Exchange Date such temporary global Bearer
Security shall be surrendered by the Common Depositary to the Trustee, as the
Company's agent for such purpose, to be exchanged, in whole or from time to time
in part, for definitive Securities of that series without charge and the Trustee
shall authenticate and deliver, in exchange for each portion of such temporary
global Bearer Security, a like aggregate principal amount of definitive
Securities of the same series of authorized denominations and of like tenor as
the portion of such temporary global Bearer Security to be exchanged; provided,
however, that unless otherwise specified in such temporary global Bearer
Security, no such definitive Securities shall be delivered unless, upon such
presentation by the Common Depositary, such temporary global Bearer Security is
accompanied by a certificate dated the Exchange Date or a subsequent date and
signed by Euroclear as to the portion of such temporary global Bearer Security
held for its account then to be exchanged and a certificate dated the Exchange
Date or a subsequent date and signed by CEDEL S.A. as to the portion of such
temporary global Bearer Security held for its account then to be exchanged, each
in the form set forth in Exhibit B to this Indenture. The definitive Securities
to be delivered in exchange for any such temporary global Bearer Security shall
be in bearer form, registered form, permanent global bearer form or permanent
global registered form, or any combination thereof, as specified as contemplated
by Section 301, and if any combination thereof is so specified, as requested by
the beneficial owner thereof.
 
     Unless otherwise specified in the temporary global Bearer Security, the
interest of a beneficial owner of Securities of a series in a temporary global
Bearer Security shall be exchanged on or after the Exchange Date for definitive
Securities (and where the form of the definitive Securities is not specified by
the Holder for an interest in a permanent global Security) of the same series
and of like tenor upon delivery by such beneficial owner to Euroclear or CEDEL
S.A., as the case may be, of a certificate in the form set forth in Exhibit A to
this Indenture dated no earlier than the Certification Date, copies of which
certificate shall be available from the offices of Euroclear and CEDEL S.A., the
Trustee, any Authenticating Agent appointed for such series of Securities and
each Paying Agent. Unless otherwise specified in such temporary global Bearer
Security, any exchange shall be made free of charge to the beneficial owners of
such temporary global Bearer Security, except that a Person receiving definitive
Securities must bear the cost of insurance, postage, transportation and
 
                                       20
<PAGE>   28
 
the like in the event that such Person does not take delivery of such definitive
Securities in person at the offices of Euroclear or CEDEL S.A. Definitive
Securities in bearer form to be delivered in exchange for any portion of a
temporary global Bearer Security shall be delivered only outside the United
States.
 
     All Outstanding temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
the same series and of like tenor authenticated and delivered hereunder, except
that, unless otherwise specified as contemplated by Section 301, interest
payable on a temporary global Bearer Security on an Interest Payment Date for
Securities of such series shall be payable to Euroclear and CEDEL S.A. on such
Interest Payment Date upon delivery by Euroclear and CEDEL S.A. to the Trustee
of a certificate or certificates in the form set forth in Exhibit B to this
Indenture, for credit without further interest on or after such Interest Payment
Date to the respective accounts of the Persons who are the beneficial owners of
such temporary global Bearer Security on such Interest Payment Date and who have
each delivered to Euroclear or CEDEL S.A., as the case may be, a certificate in
the form set forth in Exhibit A to this Indenture. Any interest so received by
Euroclear or CEDEL S.A. and not paid as herein provided shall be returned to the
Trustee immediately prior to the expiration of two years after such Interest
Payment Date in order to be repaid to the Company in accordance with Section
1103.
 
     SECTION 305. Registration, Registration of Transfer and Exchange.
 
     The Company shall cause to be kept for each series of Securities at one of
the offices or agencies maintained pursuant to Section 1102 a register (the
register maintained in such office and in any other office or agency of the
Company in a Place of Payment being herein sometimes collectively referred to as
the "Security Register") in which, subject to such reasonable regulations as it
may prescribe, the Company shall provide for the registration of Registered
Securities and of transfers of Registered Securities of such series. The Trustee
is hereby initially appointed "Security Registrar" for the purpose of
registering Securities and transfers of Securities as herein provided.
 
     Upon surrender for registration of transfer of any Registered Security of
any series at the office or agency in a Place of Payment for that series, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Registered
Securities of the same series and of like tenor, of any authorized denominations
and of a like aggregate principal amount.
 
     At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series and of like tenor,
of any authorized denominations and of a like aggregate principal amount, upon
surrender of the Securities to be exchanged at such office or agency. Whenever
any Securities are so surrendered for exchange, the Company shall execute, and
the Trustee shall authenticate and deliver, the Securities which the Holder
making the exchange is entitled to receive. A Holder of Registered Securities
cannot have Bearer Securities issued in exchange for such Registered Securities.
 
     At the option of the Holder of Bearer Securities of any series, such Bearer
Securities may be exchanged for Registered Securities of the same series of any
authorized denominations and of a like aggregate principal amount and tenor,
upon surrender of the Bearer Securities to be exchanged at any such office or
agency, with all unmatured coupons and all matured coupons in default thereto
appertaining. If the Holder of a Bearer Security is unable to produce any such
unmatured coupon or coupons or matured coupon or coupons in default, such
exchange may be effected if the Bearer Securities are accompanied by payment in
funds acceptable to the Company in an amount equal to the face amount of such
missing coupon or coupons, or the surrender of such missing coupon or coupons
may be waived by the Company and the Trustee if there is furnished to them such
security or indemnity as they may require to save each of them and any Paying
Agent harmless. If thereafter the Holder of such Security shall surrender to any
Paying Agent any such missing coupon in respect of which such a payment shall
have been made, such Holder shall be entitled to receive from the Company the
amount of such payment; provided, however, that, except as otherwise provided in
Section 1102, interest represented by coupons shall be payable only upon
presentation and surrender of those coupons at an office or agency located
outside the United States. Notwithstanding the foregoing, in case a Bearer
Security of any series is surrendered at any such office or agency in exchange
for a Registered Security of the same series and like tenor after the close of
business at such office or agency on (i) any Regular Record
 
                                       21
<PAGE>   29
 
Date and before the opening of business at such office or agency on the relevant
Interest Payment Date, or (ii) any Special Record Date and before the opening of
business at such office or agency on the related proposed date for payment of
Defaulted Interest, such Bearer Security shall be surrendered without the coupon
relating to such Interest Payment Date or proposed date for payment, as the case
may be, and interest or Defaulted Interest, as the case may be, will not be
payable on such Interest Payment Date or proposed date for payment, as the case
may be, in respect of the Registered Security issued in exchange for such Bearer
Security but will be payable only to the Holder of such coupon when due in
accordance with the provisions of this Indenture.
 
     Whenever any Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities which
the Holder making the exchange is entitled to receive.
 
     Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent global Security shall be exchangeable
only as provided in this paragraph. If the beneficial owners of interests in a
permanent global Security are entitled to exchange such interest for Securities
of such series and of like tenor and principal amount of another authorized form
and denomination, as specified as contemplated by Section 301, then without
unnecessary delay but in any event not later than the earliest date on which
such interests may be so exchanged, the Company shall deliver to the Trustee
definitive Securities of that series in an aggregate principal amount equal to
the principal amount of such permanent global Security, executed by the Company.
On or after the earliest date on which such interests may be so exchanged, such
permanent global Security shall be surrendered from time to time in accordance
with instructions given to the Trustee and the Common Depositary (which
instructions shall be in writing but need not comply with Section 103 or be
accompanied by an Opinion of Counsel) by the Common Depositary or such other
depositary or Common Depositary as shall be specified in the Company Order with
respect thereto to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or in part, for definitive Securities of the same series
without charge and the Trustee shall authenticate and deliver, in exchange for
each portion of such permanent global Security, a like aggregate principal
amount of other definitive Securities of the same series of authorized
denominations and of like tenor as the portion of such permanent global Security
to be exchanged which, unless the Securities of the series are not issuable both
as Bearer Securities and as Registered Securities, as specified as contemplated
by Section 301, shall be in the form of Bearer Securities or Registered
Securities, or any combination thereof, as shall be specified by the beneficial
owner thereof; provided, however, that no such exchanges may occur during a
period beginning at the opening of business 15 days before any selection of
Securities of that series is to be redeemed and ending on the relevant
Redemption Date; and provided, further, that no Bearer Security delivered in
exchange for a portion of a permanent global Security shall be mailed or
otherwise delivered to any location in the United States. Promptly following any
such exchange in part, such permanent global Security shall be returned by the
Trustee to the Common Depositary or such other depositary or Common Depositary
referred to above in accordance with the instructions of the Company referred to
above. If a Registered Security is issued in exchange for any portion of a
permanent global Security after the close of business at the office or agency
where such exchange occurs on (i) any Regular Record Date and before the opening
of business at such office or agency on the relevant Interest Payment Date, or
(ii) any Special Record Date and before the opening of business at such office
or agency on the related proposed date for payment of interest or Defaulted
Interest, as the case may be, will not be payable on such Interest Payment Date;
or proposed date for payment, as the case may be, in respect of such Registered
Security, but will be payable on such Interest Payment Date or proposed for
payment, as the case may be, only to the Person to whom interest in respect of
such portion of such permanent global Security is payable in accordance with the
provisions of this Indenture.
 
     All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.
 
     Every Registered Security presented or surrendered for registration of
transfer or for exchange shall (if so required by the Company or the Trustee) be
duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.
 
                                       22
<PAGE>   30
 
     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than exchange
pursuant to Section 304, 906 or 1207 not involving any transfer.
 
     The Company shall not be required (i) to issue, register the transfer of or
exchange Securities of any series during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Securities of such series selected for redemption and ending at the close of
business on (A) if Securities of the series are issuable only as Registered
Securities, the day of the mailing of the relevant notice of redemption and (B)
if Securities of the series are issuable as Bearer Securities, the day of the
first publication of the relevant notice of redemption, except that if
Securities of the series are also issuable as Registered Securities and there is
no publication, the mailing of the relevant notice of redemption or (ii) to
register the transfer of or exchange any Registered Security so selected for
redemption in whole or in part, except the unredeemed portion of any Security
being redeemed in part or (iii) to exchange any Bearer Security so selected for
redemption except that such a Bearer Security may be exchanged for a Registered
Security of that series and like tenor, provided that such Registered Security
shall be simultaneously surrendered for redemption.
 
     SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities.
 
     If any mutilated Security or a Security with a mutilated coupon
appertaining to it is surrendered to the Trustee, the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a new Security
of the same series and of like tenor and principal amount and bearing a number
not contemporaneously outstanding, with coupons corresponding to the coupons, if
any, appertaining to the surrendered Security.
 
     If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security or coupon
appertaining thereto and (ii) such security or indemnity as may be required by
them to save each of them and any agent of either of them harmless, then, in the
absence of notice to the Company or the Trustee that such Security or coupon has
been acquired by a bona fide purchaser, the Company shall execute and upon its
request the Trustee shall authenticate and deliver, in lieu of any such
destroyed, lost or stolen Security or in exchange for the Security to which a
destroyed, lost or stolen coupon appertains (with all appurtenant coupons not
destroyed, lost or stolen), a new Security of the same series and of like tenor
and principal amount and bearing a number not contemporaneously outstanding,
with coupons corresponding to the coupons, if any, appertaining to such
destroyed, lost or stolen Security or to the Security to which such destroyed,
lost or stolen coupon appertains.
 
     In case any such mutilated, destroyed, lost or stolen Security or coupon
has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, pay such Security; provided, however,
that the principal of and any premium and interest on Bearer Securities shall,
except as otherwise provided in Section 1102, be payable only at an office or
agency located outside the United States.
 
     Upon the issuance of any new Security under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee connected therewith).
 
     Every new Security of any series with its coupons, if any, issued pursuant
to this Section in lieu of any destroyed, lost or stolen Security or in exchange
for a Security to which a destroyed, lost or stolen coupon appertains shall
constitute an original additional contractual obligation of the Company, whether
or not the destroyed, lost or stolen Security and its coupons, if any, or the
destroyed, lost or stolen coupons shall be at any time enforceable by anyone,
and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of that series duly issued
hereunder.
 
     The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities or coupons.

     SECTION 307. Payment of Interest; Interest Rights Preserved.
 
     Interest on any Registered Security which is payable, and is punctually
paid or duly provided for, on any Interest Payment Date shall be paid to the
Person in whose name that Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest. Interest on any Bearer Security which is payable, and is punctually
paid or duly provided for, on any Interest Payment Date shall be paid to the
bearer of the applicable coupon appertaining to such Bearer Security. Unless
otherwise provided with respect to the Securities of any series, payment of
interest may be made at the option of the Company (i) in the case of Registered
Securities, by check mailed or delivered to the address of any Person entitled
thereto as such address shall appear in the Security Register, or (ii) in the
case of Bearer Securities, except as otherwise provided in Section 1002, upon
presentation and surrender of the appropriate coupon appertaining thereto at an
office or agency of the Company in a Place of Payment located outside the United
States or by transfer to an account maintained by the payee with a bank located
outside the United States.
 
     Any interest on any Registered Security of any series which is payable, but
is not punctually paid or duly provided for, on any Interest Payment Date
(herein called "Defaulted Interest") shall forthwith cease to be payable to the
Holder on the relevant Regular Record Date by virtue of having been such Holder,
and such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:
 
          (1) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Registered Securities of such series (or
     their respective Predecessor Securities) are registered at the close of
     business on a Special Record Date for the payment of such Defaulted
     Interest, which shall be fixed in the following manner. The Company shall
     notify the Trustee in writing of the amount of Defaulted Interest proposed
     to be paid on each Registered Security of such series and the date of the
     proposed payment, and at the same time the Company shall deposit with the
     Trustee an amount of money equal to the aggregate amount proposed to be
     paid in respect of such Defaulted Interest or shall make arrangements
     satisfactory to the Trustee for such deposit prior to the date of the
     proposed payment, such money when deposited to be held in trust for the
     benefit of the Persons entitled to such Defaulted Interest as in this
     Clause provided. Thereupon the Trustee shall fix a Special Record Date for
     the payment of such Defaulted Interest which shall be not more than 15 days
     and not less than 10 days prior to the date of the proposed payment and not
     less than 10 days after the receipt by the Trustee of the notice of the
     proposed payment. The Trustee shall promptly notify the Company of such
     Special Record Date and, in the name and at the expense of the Company,
     shall cause notice of the proposed payment of such Defaulted Interest and
     the Special Record Date therefor to be mailed, first-class postage prepaid,
     to each Holder of Registered Securities of such series at his address as it
     appears in the Security Register, not less than 10 days prior to such
     Special Record Date. The Trustee may, in its discretion, in the name and at
     the expense of the Company, cause a similar notice to be published at least
     once in an Authorized Newspaper, but such publication shall not be a
     condition precedent to the establishment of such Special Record Date.
     Notice of the proposed payment of such Defaulted Interest and the Special
     Record Date therefor having been so mailed, such Defaulted Interest shall
     be paid to the Persons in whose names the Registered Securities of such
     series (or their respective Predecessor Securities) are registered at the
     close of business on such Special Record Date and shall no longer be
     payable pursuant to the following Clause (2).
 
          (2) The Company may make payment of any Defaulted Interest on the
     Registered Securities of any series in any other lawful manner not
     inconsistent with the requirements of any securities exchange on which such
     Securities may be listed, and upon such notice as may be required by such
     exchange, if, after notice given by the Company to the Trustee of the
     proposed payment pursuant to this Clause, such manner of payment shall be
     deemed practicable by the Trustee.
 
     Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture, upon registration of transfer of, in exchange
for or in lieu of, any other Security, shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

     SECTION 308. Persons Deemed Owners.
 
     Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered as the
owner of such Registered Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Sections 305 and 307)
interest on such Registered Security and for all other purposes whatsoever,
whether or not such Security be overdue, and neither the Company, the Trustee
nor any agent of the Company or the Trustee shall be affected by notice to the
contrary.
 
     Title to any Bearer Security and any coupons appertaining thereto shall
pass by delivery. The Company, the Trustee and any agent of the Company or the
Trustee may treat the bearer of any Bearer Security and the bearer of any coupon
as the absolute owner of such Security or coupon for the purpose of receiving
payment thereof or on account thereof and for all other purposes whatsoever,
whether or not such Security or coupon be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary.
 
     SECTION 309. Cancellation.
 
     All Securities and coupons surrendered for payment, redemption,
registration of transfer or exchange or for credit against any sinking fund
payment shall, if surrendered to any Person other than the Trustee, be delivered
to the Trustee. All Registered Securities and matured coupons so delivered shall
be promptly cancelled by the Trustee. All Bearer Securities and unmatured
coupons so delivered shall be held by the Trustee and, upon instruction by a
Company Order, shall be cancelled or held for reissuance. Bearer Securities and
unmatured coupons held for reissuance may be reissued only in replacement of
mutilated, lost, stolen or destroyed Bearer Securities of the same series and
like tenor or the related coupons pursuant to Section 306. All Bearer Securities
and unmatured coupons held by the Trustee pending such cancellation or
reissuance shall be deemed to be delivered to the Trustee for all purposes of
this Indenture and the Securities. The Company may at any time deliver to the
Trustee for cancellation any Securities previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and all
Securities so delivered shall be promptly cancelled by the Trustee. No
Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section, except as expressly permitted by this
Indenture. All cancelled Securities held by the Trustee shall be disposed of as
directed by a Company Order; provided that the Trustee shall not be required to
destroy such Securities.
 
     In the case of any temporary global Bearer Security, which shall be
disposed of if the entire aggregate principal amount of the Securities
represented thereby has been exchanged, the certificate of disposition shall
state that all certificates required pursuant to Section 304 hereof,
substantially in the form of Exhibit B hereto, to be given by Euroclear or CEDEL
S.A., have been duly presented to the Trustee for such Securities by Euroclear
or CEDEL S.A., as the case may be. Permanent global Securities shall not be
disposed of until exchanged in full for definitive Securities or until payment
thereon is made in full.
 
     SECTION 310. Computation of Interest.
 
     Except as otherwise specified as contemplated by Section 301 for Securities
of any series, interest on the Securities of each series shall be computed on
the basis of a year of twelve 30-day months.
 
     SECTION 311. CUSIP Numbers.
 
     The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; provided that any such notice may
state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers.

                            GUARANTEE OF SECURITIES
 
     SECTION 401. Unconditional Guarantees.
 
     (a) For value received, (i) the Guarantors, jointly and severally, hereby
fully, unconditionally and absolutely guarantee (the "Guarantees") to the
Holders and to the Trustee the due and punctual payment of the principal of, and
premium, if any, and interest on the Guaranteed Securities and all other amounts
due and payable under this Indenture and the Guaranteed Securities by the
Company, and (ii) the Company hereby fully, unconditionally and absolutely
guarantees (the "Company Guarantee") to the Holders and to the Trustee the
obligations of the Guarantors described in clause (i), each when and as such
principal, premium, if any, and interest shall become due and payable, whether
at the stated maturity or by declaration of acceleration, call for redemption or
otherwise, according to the terms of the Guaranteed Securities and this
Indenture.
 
     (b) Failing payment when due of any amount guaranteed pursuant to the
Guarantees, for whatever reason, each Guarantor will be obligated to pay the
same immediately. Each Guarantee hereunder is intended to be a general,
unsecured, senior obligation of each Guarantor and will rank pari passu in right
of payment with all Indebtedness of each such Guarantor that is not, by its
terms, expressly subordinated in right of payment to the Guarantee of such
Guarantor. Each of the Guarantors hereby agrees that its obligations hereunder
shall be full, unconditional and absolute, irrespective of the validity,
regularity or enforceability of the Guaranteed Securities, the Guarantees or
this Indenture, the absence of any action to enforce the same, any waiver or
consent by any Holder of the Guaranteed Securities with respect to any
provisions hereof or thereof, any release of any other Guarantor, the recovery
of any judgment against the Company, any action to enforce the same or any other
circumstance which might otherwise constitute a legal or equitable discharge or
defense of a Guarantor. Each of the Guarantors hereby agrees that in the event
of a default in payment of the principal of, or premium, if any, or interest on
the Guaranteed Securities, whether at the stated maturity or by declaration of
acceleration, call for redemption or otherwise, legal proceedings may be
instituted by the Trustee on behalf of the Holders or, subject to Section 607,
by the Holders, on the terms and conditions set forth in this Indenture,
directly against each of the Guarantors to enforce the Guarantees without first
proceeding against the Company.
 
     (c) Failing payment of the Guarantees, for whatever reason, the Company
will be obligated to pay, or to perform or cause the performance of, the same
immediately. The Company Guarantee is intended to be a general, unsecured,
senior obligation of the Company and will rank pari passu in right of payment
with all Indebtedness of the Company that is not, by its terms, expressly
subordinated in right of payment to the Company Guarantee. The Company hereby
agrees that its obligations under the Company Guarantee shall be full,
unconditional and absolute, irrespective of the validity, regularity or
enforceability of the Guaranteed Securities, the Guarantees, the Company
Guarantee or this Indenture, the absence of any action to enforce the same, any
waiver or consent by any Holder of the Guaranteed Securities with respect to any
provisions hereof or thereof, the recovery of any judgment against the Company
or any Guarantor, any action to enforce the same or any other circumstance which
might otherwise constitute a legal or equitable discharge or defense of the
Company.
 
     (d) The obligations of each Guarantor and the Company under this Article 4
shall be as aforesaid full, unconditional and absolute and shall not be
impaired, modified, released or limited by any occurrence or condition
whatsoever, including, without limitation, (i) any compromise, settlement,
release, waiver, renewal, extension, indulgence or modification of, or any
change in, any of the obligations and liabilities of the Company or any
Guarantor contained in the Guaranteed Securities or this Indenture, (ii) any
impairment, modification, release or limitation of the liability of the Company,
any Guarantor or any of their estates in bankruptcy, or any remedy for the
enforcement thereof, resulting from the operation of any present or future
provision of any applicable bankruptcy law, as amended, or other statute or from
the decision of any court, (iii) the assertion or exercise by the Company, any
Guarantor or the Trustee of any rights or remedies under the Guaranteed
Securities or this Indenture or their delay in or failure to assert or exercise
any such rights or
 
                                       26
<PAGE>   34
 
remedies, (iv) the assignment or the purported assignment of any property as
security for the Guaranteed Securities, including all or any part of the rights
of the Company or any Guarantor under this Indenture, (v) the extension of the
time for payment by the Company or any Guarantor of any payments or other sums
or any part thereof owing or payable under any of the terms and provisions of
the Guaranteed Securities or this Indenture or of the time for performance by
the Company or any Guarantor of any other obligations under or arising out of
any such terms and provisions or the extension or the renewal of any thereof,
(vi) the modification or amendment (whether material or otherwise) of any duty,
agreement or obligation of the Company or any Guarantor set forth in this
Indenture, (vii) the voluntary or involuntary liquidation, dissolution, sale or
other disposition of all or substantially all of the assets, marshalling of
assets and liabilities, receivership, insolvency, bankruptcy, assignment for the
benefit of creditors, reorganization, arrangement, composition or readjustment
of, or other similar proceeding affecting, the Company or any of the Guarantors
or any of their respective assets, or the disaffirmance of the Guaranteed
Securities, the Guarantees, the Company Guarantee or this Indenture in any such
proceeding, (viii) the release or discharge of the Company or any Guarantor from
the performance or observance of any agreement, covenant, term or condition
contained in any of such instruments by operation of law, (ix) the
unenforceability of the Guaranteed Securities, the Guarantees, the Company
Guarantee or this Indenture or (x) any other circumstance which might otherwise
constitute a legal or equitable discharge of a surety or guarantor.
 
     (e) The Guarantors and the Company each hereby (i) waives diligence,
presentment, demand of payment, filing of claims with a court in the event of
the merger, insolvency or bankruptcy of the Company or a Guarantor, and all
demands whatsoever, (ii) acknowledges that any agreement, instrument or document
evidencing the Guarantees or the Company Guarantee may be transferred and that
the benefit of its obligations hereunder shall extend to each holder of any
agreement, instrument or document evidencing the Guarantees or the Company
Guarantee without notice to them and (iii) covenants that its Guarantee or the
Company Guarantee, as the case may be, will not be discharged except by complete
performance of the Guarantees or the Company Guarantee, as the case may be. Each
Guarantor and the Company further agrees that if at any time all or any part of
any payment theretofore applied by any Person to any Guarantee or the Company
Guarantee is, or must be, rescinded or returned for any reason whatsoever,
including without limitation, the insolvency, bankruptcy or reorganization of
the Company or any Guarantor, such Guarantee or the Company Guarantee, as the
case may be, shall, to the extent that such payment is or must be rescinded or
returned, be deemed to have continued in existence notwithstanding such
application, and the Guarantees or the Company Guarantee, as the case may be,
shall continue to be effective or be reinstated, as the case may be, as though
such application had not been made.
 
     (f) Each Guarantor shall be subrogated to all rights of the Holders and the
Trustee against the Company in respect of any amounts paid by such Guarantor
pursuant to the provisions of this Indenture, provided, however, that no
Guarantor shall be entitled to enforce or to receive any payments arising out
of, or based upon, such right of subrogation until all of the Guaranteed
Securities and the Guarantees shall have been paid in full or discharged.
 
     (g) A director, officer, employee or stockholder, as such, of any Guarantor
shall not have any liability for any obligations of such Guarantor under this
Indenture or for any claim based on, in respect of or by reason of such
obligations or their creation.
 
     SECTION 402. Limitation of Guarantor's Liability.
 
     Each Guarantor and by its acceptance hereof each Holder hereby confirms
that it is the intention of all such parties that the guarantee by such
Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or
conveyance for purposes of any federal, state or foreign law. To effectuate the
foregoing intention, the Holders and each Guarantor hereby irrevocably agree
that the obligations of each Guarantor under its Guarantee shall be limited to
the maximum amount as will, after giving effect to all other contingent and
fixed liabilities of such Guarantor and after giving effect to any collections
from or payments made by or on behalf of any other Guarantor in respect of the
obligations of such other Guarantor under its Guarantee or pursuant to Section
403, result in the obligations of such Guarantor under its Guarantee not
constituting a fraudulent conveyance or fraudulent transfer under federal, state
or foreign law.
 
                                       27
<PAGE>   35
 
     SECTION 403. Contribution.
 
     In order to provide for just and equitable contribution among the
Guarantors, the Guarantors agree, inter se, that in the event any payment or
distribution is made by any Guarantor (a "Funding Guarantor") under its
Guarantee, such Funding Guarantor shall be entitled to a contribution from each
other Guarantor in a pro rata amount based on the Adjusted Net Assets of each
Guarantor (including the Funding Guarantor) for all payments, damages and
expenses incurred by the Funding Guarantor in discharging the Company's
obligations with respect to the Guaranteed Securities or any other Guarantor's
obligations with respect to its Guarantee.
 
     SECTION 404. Execution and Delivery of Guarantees.
 
     To further evidence the Guarantees set forth in Section 401, each Guarantor
hereby agrees that a notation relating to such Guarantees shall be endorsed on
each Guaranteed Security authenticated and delivered by the Trustee and executed
by either manual or facsimile signature of two Officers of each Guarantor.
 
     Each of the Guarantors hereby agrees that its Guarantee set forth in
Section 401 shall remain in full force and effect notwithstanding any failure to
endorse on each Security a notation relating to such Guarantee.
 
     If an Officer of a Guarantor whose signature is on this Indenture or a
Security no longer holds that office at the time the Trustee authenticates such
Security or at any time thereafter, such Guarantor's Guarantee of such Security
shall be valid nevertheless.
 
     The delivery of any Security by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of any Guarantee set forth in
this Indenture on behalf of the Guarantor.
 
     SECTION 405. Addition of Guarantors.
 
     (a) If any Subsidiary of the Company guarantees any Funded Indebtedness of
the Company other than the Guaranteed Securities at any time subsequent to the
Issue Date (including, without limitation, following any release of such
Subsidiary pursuant to Section 406 from any Guarantee previously provided by it
under this Article 4), then the Company shall (i) cause the Guaranteed
Securities to be equally and ratably guaranteed by such Subsidiary, but only to
the extent that the Guaranteed Securities are not already guaranteed by such
Subsidiary on reasonably comparable terms and (ii) cause such Subsidiary to
execute and deliver a supplemental indenture evidencing its provision of a
Guarantee in accordance with clause (b) below.
 
     (b) Any Person that was not a Guarantor on the Issue Date may become a
Guarantor by executing and delivering to the Trustee (i) a supplemental
indenture in form and substance satisfactory to the Trustee, which subjects such
Person to the provisions (including the representations and warranties) of this
Indenture as a Guarantor and (ii) an Opinion of Counsel and Officers'
Certificate to the effect that such supplemental indenture has been duly
authorized and executed by such Person and constitutes the legal, valid, binding
and enforceable obligation of such Person (subject to such customary exceptions
concerning creditors' rights and equitable principles as may be acceptable to
the Trustee in its discretion and provided that no opinion need be rendered
concerning the enforceability of the Guarantee).
 
     SECTION 406. Release of Guarantee.
 
     Notwithstanding anything to the contrary in this Article 4, in the event
that any Guarantor shall no longer be a guarantor of any Funded Indebtedness of
the Company other than the Guaranteed Securities, and so long as no default or
Event of Default shall have occurred or be continuing, such Guarantor, upon
giving notice to the Trustee to the foregoing effect, shall be deemed to be
released from all of its obligations under this Indenture and the Guarantee of
such Guarantor shall be of no further force or effect. Following the receipt by
the Trustee of any such notice, the Company shall cause this Indenture to be
amended as provided in Section 1001; provided, however, that the failure to so
amend this Indenture shall not affect the validity of the termination of the
Guarantee of such Guarantor.

<PAGE>   36
 
     SECTION 407. Consent to Jurisdiction and Service of Process.
 
     Each Guarantor that is not organized under the laws of the United States
(including the States and the District of Columbia) (each a "Non-U.S.
Guarantor") hereby appoints the principal office of CT Corporation System in The
City of New York which, on the date hereof, is located at 1633 Broadway, New
York, New York 10019, as the authorized agent thereof (the "Authorized Agent")
upon whom process may be served in any action, suit or proceeding arising out of
or based on this Indenture or the Guaranteed Securities which may be instituted
in the Supreme Court of the State of New York or the United States District
Court for the Southern District of New York, in either case in The Borough of
Manhattan, The City of New York, by the Holder of any Security, and each
Non-U.S. Guarantor hereby waives any objection which it may now or hereafter
have to the laying of venue of any such proceeding and expressly and irrevocably
accepts and submits, for the benefit of the Holders from time to time of the
Guaranteed Securities, to the nonexclusive jurisdiction of any such court in
respect of any such action, suit or proceeding, for itself and with respect to
its properties, revenues, and assets. Such appointment shall be irrevocable
unless and until the appointment of a successor authorized agent for such
purpose, and such successor's acceptance of such appointment, shall have
occurred. Each Non-U.S. Guarantor agrees to take any and all actions, including
the filing of any and all documents and instruments, that may be necessary to
continue such appointment in full force and effect as aforesaid. Service of
process upon the Authorized Agent with respect to any such action shall be
deemed, in every respect, effective service of process upon any such Non-U.S.
Guarantor. Notwithstanding the foregoing, any action against any Non-U.S.
Guarantor arising out of or based on any Security may also be instituted by the
Holder of such Security in any court in the jurisdiction of any such court in
any such action. The Company shall require the Authorized Agent to agree in
writing to accept the foregoing appointment as agent for service of process.
 
     SECTION 408. Waiver of Immunity.
 
     To the extent that any Non-U.S. Guarantor or any of its properties, assets
or revenues may have or may hereafter become entitled to, or have attributed to
it, any right of immunity, on the grounds of sovereignty or otherwise, from any
legal action, suit or proceeding, from the giving of any relief in any thereof,
from set-off or counterclaim, from the jurisdiction of any court, from service
of process, from attachment upon or prior to judgment, from attachment in aid of
execution of judgment, or from execution of judgment, or other legal process or
proceeding for the giving of any relief or for the enforcement of any judgment,
in any jurisdiction in which proceedings may at any time be commenced, with
respect to its obligations, liabilities or any other matter under or arising out
of or in connection with this Indenture or the Guaranteed Securities, such Non-
U.S. Guarantor, to the maximum extent permitted by law, hereby irrevocably and
unconditionally waives, and agrees not to plead or claim, any such immunity and
consents to such relief and enforcement.
 
     SECTION 409. Judgment Currency.
 
     Each Non-U.S. Guarantor agrees to indemnify the Trustee and each Holder
against any loss incurred by the Trustee or such Holder in connection with this
Indenture as a result of any judgment or order being given or made and expressed
and paid in a currency (the "Judgment Currency") other than United States
dollars and as a result of any variation as between (i) the rate of exchange at
which the United States dollar amount is converted into the Judgment Currency
for the purpose of such judgment or order and (ii) the spot rate of exchange in
The City of New York at which the Trustee or such Holder on the date of payment
of such judgment or order is able to purchase United States dollars with the
amount of the Judgment Currency actually received by the Trustee or such Holder.
The foregoing indemnity shall constitute a separate and independent obligation
of each Non-U.S. Guarantor and shall continue in full force and effect
notwithstanding any such judgment or order as aforesaid. The term "spot rate of
exchange" shall include any premiums and costs of exchange in connection with
the purchase of, or conversion into, United States dollars.

     SECTION 501. Satisfaction and Discharge of Indenture.
 
     This Indenture shall upon Company Request cease to be of further effect
with respect to Securities of a series, and the Trustee, at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture with respect to Securities of such series, when
 
        (1) either
 
             (a) all Securities of such series theretofore authenticated and
        delivered and all coupons, if any, appertaining thereto (other than (i)
        coupons appertaining to Bearer Securities surrendered for exchange for
        Registered Securities and maturing after such exchange, whose surrender
        is not required or has been waived as provided in Section 305, (ii)
        Securities and coupons which have been destroyed, lost or stolen and
        which have been replaced or paid as provided in Section 306, (iii)
        coupons appertaining to Bearer Securities called for redemption and
        maturing after the relevant Redemption Date, whose surrender has been
        waived as provided in Section 1106, and (iv) Securities and coupons for
        whose payment money has theretofore been deposited in trust or
        segregated and held in trust by the Company and thereafter repaid to the
        Company or discharged from such trust, as provided in Section 1003) have
        been delivered to the Trustee for cancellation; or
 
             (b) with respect to all Outstanding Securities of such series and
        any coupons appertaining thereto not theretofore delivered to the
        Trustee for cancellation, the Company has deposited or caused to be
        deposited with the Trustee as trust funds, under the terms of an
        irrevocable trust agreement in form and substance satisfactory to the
        Trustee, for the purpose money or U.S. Government Obligations maturing
        as to principal and interest in such amounts and at such times as will,
        together with the income to accrue thereon, without consideration of any
        reinvestment thereof, be sufficient to pay and discharge the entire
        indebtedness on all Outstanding Securities of such series and coupons
        appertaining thereto not theretofore delivered to the Trustee for
        cancellation for principal (and premium and Additional Amounts, if any)
        and interest to the Stated Maturity or any Redemption Date contemplated
        by the penultimate paragraph of this Section, as the case may be; or
 
             (c) the Company has properly fulfilled such other means of
        satisfaction and discharge as is specified, as contemplated by Section
        301, to be applicable to the Securities of such series;
 
        (2) the Company has paid or caused to be paid all other sums payable
     hereunder by the Company with respect to the Outstanding Securities of such
     series;
 
        (3) the Company has complied with any other conditions specified
     pursuant to Section 301 to be applicable to the discharge of Securities of
     such series pursuant to this Section 501;
 
        (4) the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent
     herein provided for relating to the satisfaction and discharge of this
     Indenture with respect to the Outstanding Securities of such series have
     been complied with;
 
        (5) if the conditions set forth in Section 501(1)(a) have not been
     satisfied, and unless otherwise specified pursuant to Section 301 for the
     Securities of such series, the Company has delivered to the Trustee an
     Opinion of Counsel to the effect that the Holders of Securities of such
     series will not recognize income, gain or loss for United States federal
     income tax purposes as a result of such deposit, satisfaction and discharge
     and will be subject to United States federal income tax on the same amount
     and in the same manner and at the same time as would have been the case if
     such deposit, satisfaction and discharge had not occurred; and
 
        (6) no default or Event of Default with respect to the Securities of
     such issue shall have occurred and be continuing on the date of such
     deposit or, in so far as clause (5) or (6) of Section 601 is
 
                                       30
<PAGE>   38
 
     concerned, at any time in the period ending on the 91st day after the date
     of such deposit (it being understood that this condition shall not be
     deemed satisfied until the expiration of such period).
 
     For the purposes of this Indenture, "U.S. Government Obligations" means
direct non-callable obligations of, or non-callable obligations the payment of
principal of and interest on which is guaranteed by, the United States of
America, or to the payment of which obligations or guarantees the full faith and
credit of the United States of America is pledged, or beneficial interests in a
trust the corpus of which consists exclusively of money or such obligations or a
combination thereof.
 
     If any Outstanding Securities of such series are to be redeemed prior to
their Stated Maturity, whether pursuant to any optional redemption provisions or
in accordance with any mandatory sinking fund requirement, the trust agreement
referred to in subclause (b) of clause (1) of this Section shall provide
therefor and the Company shall make such arrangements as are satisfactory to the
Trustee for the giving of notice of redemption by the Trustee in the name, and
at the expense, of the Company.
 
     Notwithstanding the satisfaction and discharge of this Indenture with
respect to the Outstanding Securities of such series pursuant to this Section
501, the obligations of the Company to the Trustee under Section 707, the
obligations of the Trustee to any Authenticating Agent under Section 714 and,
except for a discharge pursuant to subclause (A) of clause (1) of this Section,
the obligations of the Company under Sections 305, 306, 504, 710(e), 701, 1101
and 1102 and the obligations of the Trustee under Section 502 and the last
paragraph of Section 1103 shall survive.
 
     SECTION 502. Application of Trust Money.
 
     Subject to the provisions of the last paragraph of Section 1103, all money
deposited with the Trustee pursuant to Section 501 shall be held in trust and
applied by it, in accordance with the provisions of the Securities, the coupons
and this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if
any) and interest and Additional Amounts for the payment of which such money has
been deposited with the Trustee.
 
     SECTION 503. Discharge of Liability on Securities of Any Series.
 
     If this Section is specified, as contemplated by Section 301, to be
applicable to Securities of any series, the Company shall be deemed to have paid
and discharged the entire indebtedness on all the Outstanding Securities of such
series, the obligation of the Company under this Indenture and the Securities of
such series to pay the principal of (and premium, if any) and interest on
Securities of such series, and any coupon appertaining thereto, shall cease,
terminate and be completely discharged and the Trustee, at the expense of the
Company, shall execute proper instruments acknowledging such satisfaction and
discharge, when
 
          (1) the Company has complied with the provisions of Section 501 of
     this Indenture (other than any additional conditions specified pursuant to
     Sections 301 and 501(3) and except that the opinion referred to in Section
     501(5) shall state that it is based on a ruling by the Internal Revenue
     Service or other change since the date hereof under applicable federal
     income tax law) with respect to all Outstanding Securities of such series,
 
          (2) the Company has delivered to the Trustee a Company Request
     requesting such satisfaction and discharge,
 
          (3) the Company has complied with any other conditions specified
     pursuant to Section 301 to be applicable to the discharge of Securities of
     such series pursuant to this Section 503, and
 
          (4) the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent
     herein provided for relating to the discharge of the indebtedness on the
     Outstanding Securities of such series have been complied with.
 
                                       31

     Upon the satisfaction of the conditions set forth in this Section with
respect to all the Outstanding Securities of any series, the terms and
conditions of such series, including the terms and conditions with respect
thereto set forth in this Indenture, shall no longer be binding upon, or
applicable to, the Company; provided that, the Company shall not be discharged
from any payment obligations in respect of Securities of such series which are
deemed not to be Outstanding under clause (iii) of the definition thereof if
such obligations continue to be valid obligations of the Company under
applicable law or pursuant to Section 305 or 306.
 
     SECTION 504. Reinstatement.
 
     If the Trustee or Paying Agent is unable to apply any money or U.S.
Government Obligations deposited with respect to Securities of any series in
accordance with Section 501 by reason of any legal proceeding or by reason of
any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, the Company's obligations
under this Indenture with respect to the Securities of such series and the
Securities of such series shall be revived and reinstated as though no deposit
had occurred pursuant to Section 501 until such time as the Trustee or Paying
Agent is permitted to apply all such money or U.S. Government Obligations in
accordance with Section 501; provided, however, that if the Company has made any
payment of principal of (or premium, if any), or interest on and any Additional
Amounts with respect to any Securities because of the reinstatement of its
obligations, the Company shall be subrogated to the rights of the Holders of
such Securities to receive such payment from the money or U.S. Government
Obligations held by the Trustee or Paying Agent.

     SECTION 601. Events of Default.
 
     "Event of Default", wherever used herein with respect to Securities of any
series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body),
unless it is either inapplicable to a particular series or it is specifically
deleted or modified in or pursuant to the supplemental indenture or Board
Resolution establishing such series of Securities, or in the form of Security
for such series:
 
          (1) default in the payment of any interest or any Additional Amounts
     upon any Security of that series when such interest or Additional Amounts
     become due and payable, and continuance of such default for a period of 30
     days; or
 
          (2) default in the payment of the principal of (or premium, if any,
     on) any Security of that series at its Maturity; or
 
          (3) default in the deposit of any sinking fund payment, when and as
     due by the terms of a Security of that series; or
 
          (4) default in the performance or breach of any covenant or warranty
     of the Company in this Indenture (other than a covenant or warranty a
     default in whose performance or whose breach is elsewhere in this Section
     specifically dealt with or which has expressly been included in this
     Indenture solely for the benefit of one or more series of Securities other
     than that series), and continuance of such default or breach for a period
     of 60 days after there has been given, by registered or certified mail, to
     the Company by the Trustee or to the Company and the Trustee by the Holders
     of at least 25% in principal amount of all Outstanding Securities a written
     notice specifying such default or breach and requiring it to be remedied
     and stating that such notice is a "Notice of Default" hereunder; or
 
          (5) the entry by a court having jurisdiction in the premises of (A) a
     decree or order for relief in respect of the Company in an involuntary case
     or proceeding under any applicable federal or state
 
                                       32
<PAGE>   40
 
     bankruptcy, insolvency, reorganization or other similar law or (B) a decree
     or order adjudging the Company a bankrupt or insolvent, or approving as
     properly filed a petition seeking reorganization, arrangement, adjustment
     or composition of or in respect of the Company under any applicable federal
     or state law, or appointing a custodian, receiver, liquidator, assignee,
     trustee, sequestrator or other similar official of the Company or of any
     substantial part of its property, or ordering the winding up or liquidation
     of its affairs, and the continuance of any such decree or order for relief
     or any such other decree or order unstayed and in effect for a period of 60
     consecutive days; or
 
          (6) the commencement by the Company of a voluntary case or proceeding
     under any applicable federal or state bankruptcy, insolvency,
     reorganization or other similar law or of any other case or proceeding to
     be adjudicated a bankrupt or insolvent, or the consent by it to the entry
     of a decree or order for relief in respect of the Company in an involuntary
     case or proceeding under any applicable federal or state bankruptcy,
     insolvency, reorganization or other similar law or to the commencement of
     any bankruptcy or insolvency case or proceeding against it, or the filing
     by it, of a petition or answer or consent seeking reorganization or relief
     under any applicable federal or state law, or the consent by it to the
     filing of such petition or to the appointment of or taking possession by a
     custodian, receiver, liquidator, assignee, trustee, sequestrator or similar
     official of the Company or of any substantial part of its property, or the
     making by it of an assignment for the benefit of creditors, or the
     admission by it in writing of its inability to pay its debts generally as
     they become due, or the taking of corporate action by the Company in
     furtherance of any such action; or
 
          (7) any default shall occur which results in the acceleration of the
     maturity of any Indebtedness of the Company or any Restricted Subsidiary
     (other than the Securities or any Non-Recourse Indebtedness) having an
     outstanding principal amount of $20 million or more individually or, taken
     together with all other such Indebtedness that has been so accelerated, in
     the aggregate; or any default shall occur in the payment of any principal
     or interest in respect of any Indebtedness of the Company or any Restricted
     Subsidiary (other than the Securities or any Non-Recourse Indebtedness)
     having an outstanding principal amount of $20 million or more individually
     or, taken together with all other such Indebtedness with respect to which
     any such payment has not been made, in the aggregate and such default shall
     be continuing for a period of 30 days without the Company or such
     Restricted Subsidiary, as the case may be, effecting a cure of such
     default.
 
     Notwithstanding the foregoing provisions of this Section 601, if the
principal of (and premium, if any) or any interest on, or Additional Amounts
with respect to, any Security is payable in a currency or currencies (including
a composite currency) other than Dollars and such currency (or currencies) is
(or are) not available to the Company for making payment thereof due to the
imposition of exchange controls or other circumstances beyond the control of the
Company (a "Conversion Event"), the Company will be entitled to satisfy its
obligations to Holders of the Securities by making such payment in Dollars in an
amount equal to the Dollar equivalent of the amount payable in such other
currency, as determined by the Company by reference to the noon buying rate in
The City of New York for cable transfers for such currency ("Exchange Rate"), as
such Exchange Rate is certified for customs purposes by the Federal Reserve Bank
of New York on the date of such payment, or, if such rate is not then available,
on the basis of the most recently available Exchange Rate. Notwithstanding the
foregoing provisions of this Section 601, any payment made under such
circumstances in Dollars where the required payment is in a currency other than
Dollars will not constitute an Event of Default under this Indenture.
 
     Promptly after the occurrence of a Conversion Event, the Company shall give
written notice thereof to the Trustee; and the Trustee, promptly after receipt
of such notice, shall give notice thereof in the manner provided in Section 106
to the Holders. Promptly after the making of any payment in Dollars as a result
of a Conversion Event, the Company shall give notice in the manner provided in
Section 106 to the Holders, setting forth the applicable Exchange Rate and
describing the calculation of such payments.

     SECTION 602. Acceleration of Maturity; Rescission and Annulment.
 
     If an Event of Default with respect to any Securities of any series at the
time Outstanding occurs and is continuing, then in every such case the Trustee
or the Holders of not less than 25% in principal amount of the Outstanding
Securities of (i) the series affected by such default (in the case of an Event
of Default described in clause (1), (2), (3) or (7) of Section 601) or (ii) all
series of Securities (subject to the immediately following sentence, in the case
of other Events of Default) may declare the principal amount (or, if any such
Securities are Original Issue Discount Securities, such portion of the principal
amount as may be specified in the terms of that series) of all of the Securities
of the series affected by such default or all series, as the case may be, to be
due and payable immediately, by a notice in writing to the Company (and to the
Trustee if given by Holders), and upon any such declaration such principal
amount (or specified amount) shall become immediately due and payable. If an
Event of Default described in clause (5) or (6) of Section 601 shall occur, the
principal amount of the Outstanding Securities of all series ipso facto shall
become and be immediately due and payable without any declaration or other act
on the part of the Trustee or any Holder.
 
     At any time after such a declaration of acceleration with respect to
Securities of any series (or of all series, as the case may be) has been made
and before a judgment or decree for payment of the money due has been obtained
by the Trustee as hereinafter in this Article provided, the Holders of a
majority in principal amount of the Outstanding Securities of that series (or of
all series, as the case may be), by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if
 
          (1) the Company has paid or deposited with the Trustee a sum
     sufficient to pay
 
             (a) all overdue interest on, and any Additional Amounts with
        respect to, all Securities of that series (or of all series, as the case
        may be) and any coupons appertaining thereto,
 
             (b) the principal of (and premium, if any, on) any Securities of
        that series (or of all series, as the case may be) which have become due
        otherwise than by such declaration of acceleration and interest thereon
        at the rate or rates prescribed therefor in such Securities (in the case
        of Original Issue Discount Securities, the Securities' Yield to
        Maturity),
 
             (c) to the extent that payment of such interest is lawful, interest
        upon overdue interest and any Additional Amounts at the rate or rates
        prescribed therefor in such Securities (in the case of Original Issue
        Discount Securities, the Securities' Yield to Maturity), and
 
             (d) all sums paid or advanced by the Trustee hereunder and the
        reasonable compensation, expenses, disbursements and advances of the
        Trustee, its agents and counsel;
 
     and
 
          (2) all Events of Default with respect to Securities of that series
     (or of all series, as the case may be), other than the non-payment of the
     principal of Securities of that series (or of all series, as the case may
     be) which have become due solely by such declaration of acceleration, have
     been cured or waived as provided in Section 613.
 
No such rescission shall affect any subsequent default or impair any right
consequent thereon.
 
          SECTION 603.Collection of Indebtedness and Suits for Enforcement by
                      Trustee.
 
     The Company covenants that if
 
          (1) default is made in the payment of any installment of interest on,
     or any Additional Amounts with respect to, any Security of any series and
     any coupons appertaining thereto when such interest or Additional Amounts
     shall have become due and payable and such default continues for a period
     of 30 days, or
 
          (2) default is made in the payment of the principal of (or premium, if
     any, on) any Security at the Maturity thereof,
 
                                       34
<PAGE>   42
 
the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities and coupons, the whole amount then due and payable on
such Securities and coupons for principal (and premium, if any) and interest and
Additional Amounts and, to the extent that payment of such interest shall be
legally enforceable, interest on any overdue principal (and premium, if any) and
on any overdue interest and Additional Amounts, at the rate or rates prescribed
therefor in such Securities (or in the case of Original Issue Discount
Securities, the Securities' Yield to Maturity), and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.
 
     If the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Securities, wherever
situated.
 
     If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series and any
related coupons by such appropriate judicial proceedings as the Trustee shall
deem most effectual to protect and enforce any such rights, whether for the
specific enforcement of any covenant or agreement in this Indenture or in aid of
the exercise of any power granted herein, or to enforce any other proper remedy.
 
     SECTION 604. Trustee May File Proofs of Claim.
 
     In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal (or lesser amount
in the case of Original Issue Discount Securities) of the Securities shall then
be due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand on the Company
for the payment of overdue principal (premium, if any), interest or Additional
Amounts) shall be entitled and empowered, by intervention in such proceeding or
otherwise,
 
          (i) to file and prove a claim for the whole amount of principal (or
     lesser amount in the case of Original Issue Discount Securities) (and
     premium, if any) and interest and any Additional Amounts owing and unpaid
     in respect of the Securities or any coupons appertaining thereto and to
     file such other papers or documents as may be necessary or advisable in
     order to have the claims of the Trustee (including any claim for the
     reasonable compensation, expenses, disbursements and advances of the
     Trustee, its agents and counsel) and of the Holders allowed in such
     judicial proceeding, and
 
          (ii) to collect and receive any monies, or other property payable or
     deliverable on any such claims and to distribute the same;
 
and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 707.
 
     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceedings; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official.

     SECTION 605. Trustee May Enforce Claims Without Possession of Securities or
                  Coupons.
 
     All rights of action and claim under this Indenture or the Securities or
coupons may be prosecuted and enforced by the Trustee without possession of any
of the Securities or coupons or the production thereof in any proceeding
relating thereto, and any such proceeding instituted by the Trustee shall be
brought in its own name as trustee of an express trust, and any recovery of
judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be
for the ratable benefit of the Holders of the Securities and coupons in respect
of which such judgment has been recovered.
 
     SECTION 606. Application of Money Collected.
 
     Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium,
if any), interest or any Additional Amounts, upon presentation of the
Securities, or coupons, or both as the case may be, and the notation thereon of
the payment if only partially paid and upon surrender thereof if fully paid:
 
          FIRST: To the payment of all amounts due the Trustee under Section
     707;
 
          SECOND: To the payment of the amounts then due and unpaid for
     principal of (and premium, if any) and interest and any Additional Amounts
     on the Securities and coupons in respect of which or for the benefit of
     which such money has been collected, ratably, without preference or
     priority of any kind, according to the amounts due and payable on such
     Securities; and coupons for principal (and premium, if any), interest and
     Additional Amounts, respectively; and
 
          THIRD: The balance, if any, to the Person or Persons entitled thereto.
 
     To the fullest extent allowed under applicable law, if for the purpose of
obtaining judgment against the Company in any court it is necessary to convert
the sum due in respect of the principal of (or premium, if any) or interest on
the Securities of any series (the "Required Currency") into the Judgment
Currency, the rate of exchange used shall be the rate at which in accordance
with normal banking procedures the Trustee could purchase in The City of New
York the Required Currency with the Judgment Currency on the New York Business
Day next preceding that on which final judgment is given. Neither the Company
nor the Trustee shall be liable for any shortfall nor shall it benefit from any
windfall in payments to Holders of Securities under this Section caused by a
change in exchange rates between the time the amount of a judgment against it is
calculated as above and the time the Trustee converts the Judgment Currency into
the Required Currency to make payments under this Section to Holders of
Securities, but payment of such judgment shall discharge all amounts owed by the
Company on the claim or claims underlying such judgment.
 
     SECTION 607. Limitation on Suits.
 
     No Holder of any Security of any series or any related coupons shall have
any right to institute any proceeding, judicial or otherwise, with respect to
this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless
 
          (1) an Event of Default with respect to Securities of such series
     shall have occurred and be continuing and such Holder has previously given
     written notice to the Trustee of such continuing Event of Default;
 
          (2) the Holders of not less than 25% in principal amount of the
     Outstanding Securities of that series shall have made written request to
     the Trustee to institute proceedings in respect of such Event of Default in
     its own name as Trustee hereunder;
 
          (3) such Holder or Holders have offered to the Trustee reasonable
     indemnity against the costs, expenses and liabilities to be incurred in
     compliance with such request;
 
                                       36
<PAGE>   44
 
          (4) the Trustee for 60 days after its receipt of such notice, request
     and offer of indemnity has failed to institute any such proceeding; and
 
          (5) no direction inconsistent with such written request has been given
     to the Trustee during such 60-day period by the Holders of a majority in
     principal amount of the Outstanding Securities of that series;
 
it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.
 
     SECTION 608. Unconditional Right of Holders to Receive Principal, Premium
                  and Interest.
 
     Notwithstanding any other provision in this Indenture, the Holder of any
Security or coupon shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Section 307) interest on and any Additional Amounts with respect to such
Security or payment of such coupon on the Stated Maturity or Maturities
expressed in such Security or coupon (or, in the case of redemption, on the
Redemption Date) and to institute suit for the enforcement of any such payment,
and such rights shall not be impaired without the consent of such Holder.
 
     SECTION 609. Restoration of Rights and Remedies.
 
     If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then and in every such case, subject to any determination in
such proceeding, the Company, the Trustee and the Holders shall be restored
severally and respectively to their former positions hereunder and thereafter
all rights and remedies of the Trustee and the Holders shall continue as though
no such proceeding has been instituted.
 
     SECTION 610. Rights and Remedies Cumulative.
 
     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities or coupons in the last paragraph
of Section 306, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.
 
     SECTION 611. Delay or Omission Not Waiver.
 
     No delay or omission of the Trustee or of any Holder of any Securities or
coupons to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of
Default or an acquiescence therein. Every right and remedy given by this Article
or by law to the Trustee or to the Holders may be exercised from time to time,
and as often as may be deemed expedient, by the Trustee or by the Holders, as
the case may be.

     SECTION 612. Control by Holders.
 
     With respect to Securities of any series, the holders of a majority in
principal amount of the Outstanding Securities of such series shall have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred on
the Trustee, relating to or arising under an Event of Default described in
clause (1), (2), (3) or (7) of Section 601, and with respect to all Securities
the Holders of a majority in principal amount of all Outstanding Securities
shall have the right to direct the time, method and place of conducting any
remedy available to the Trustee, or exercising any trust or power conferred on
the Trustee, not relating to or arising under such an Event of Default, provided
that in each such case
 
          (1) such direction shall not be in conflict with any rule of law or
     with this Indenture, and
 
          (2) the Trustee may take any other action deemed proper by the Trustee
     which is not inconsistent with such direction.
 
     SECTION 613. Waiver of Past Defaults.
 
     The Holders of a majority in principal amount of the Outstanding Securities
of any series may on behalf of the Holders of all the Securities of such series
waive any past default hereunder with respect to such series and its
consequences, and the Holders of a majority in principal amount of all
Outstanding Securities may on behalf of the Holders of all Securities waive any
other past default hereunder and its consequences, except in each case a default
 
          (1) in the payment of the principal of (or premium, if any) or
     interest on, or any Additional Amounts with respect to, any Security, or
 
          (2) in respect of a covenant or provision hereof which under Article
     Ten cannot be modified or amended without the consent of the Holder of each
     Outstanding Security affected.
 
     Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.
 
     SECTION 614. Undertaking for Costs.
 
     All parties to this Indenture agree, and each Holder of any Security or
coupon by his acceptance thereof shall be deemed to have agreed, that any court
may in its discretion require, in any suit for the enforcement of any right or
remedy under this Indenture, or in any suit against the Trustee for any action
taken, suffered or omitted by it as Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court
may in its discretion assess reasonable costs, including reasonable attorneys'
fees, against any party litigant in such suit, having due regard to the merits
and good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in principal
amount of the Outstanding Securities of any series, or to any suit instituted by
any Holder for the enforcement of the payment of the principal of (or premium,
if any) or interest on, or any Additional Amounts with respect to, any Security
or the payment of any coupon on or after the Stated Maturity or Maturities
expressed in such Security or coupon (or, in the case of redemption, on or after
the Redemption Date).
 
     SECTION 615. Waiver of Stay or Extension Laws.
 
     The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power
 
                                       38

herein granted to the Trustee, but will suffer and permit the execution of every
such power as though no such law had been enacted.

                                  THE TRUSTEE
 
     SECTION 701. Certain Duties and Responsibilities.
 
     (a) Except during the continuance of an Event of Default with respect to
the Securities of any series,
 
          (1) the Trustee undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture, and no implied covenants
     or obligations shall be read into this Indenture against the Trustee; and
 
          (2) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture; but in
     the case of any such certificates or opinions which by any provision hereof
     are specifically required to be furnished to the Trustee, the Trustee shall
     be under a duty to examine the same to determine whether or not they
     conform to the requirements of this Indenture.
 
     (b) In case an Event of Default has occurred and is continuing with respect
to the Securities of any series, the Trustee shall exercise such of the rights
and powers vested in it by this Indenture, and use the same degree of care and
skill in their exercise, as a prudent man would exercise or use under the
circumstances in the conduct of his own affairs.
 
     (c) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own willful misconduct, except that
 
          (1) this Subsection shall not be construed to limit the effect of
     Subsection (a) of this Section;
 
          (2) the Trustee shall not be liable for any error of judgment made in
     good faith by a Responsible Officer, unless it shall be proved that the
     Trustee was negligent in ascertaining the pertinent facts;
 
          (3) the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the direction
     of the Holders of a majority in principal amount of the Outstanding
     Securities of any series or of all series, determined as provided in
     Section 612, relating to the time, method and place of conducting any
     proceeding for any remedy available to the Trustee, or exercising any trust
     or power conferred upon the Trustee, under this Indenture with respect to
     the Securities of such series; and
 
          (4) no provision of this Indenture shall require the Trustee to expend
     or risk its own funds or otherwise incur any financial liability in the
     performance of any of its duties hereunder, or in the exercise of any of
     its rights or powers, if it shall have reasonable grounds for believing
     that repayment of such funds or adequate indemnity against such risk or
     liability is not reasonably assured to it.
 
     (d) Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section.
 
     SECTION 702. Notice of Defaults.
 
     Within 90 days after the occurrence of any default hereunder with respect
to the Securities of any series, the Trustee shall give notice of such default
hereunder known to the Trustee to all Holders of Securities of such series in
the manner provided in Section 106, unless such default shall have been cured or
waived; provided, however, that, except in the case of a default in the payment
of the principal of (or premium, if any)
 
                                       39

or interest on, or any Additional Amounts with respect to, any Security of such
series or in the payment of any sinking fund installment with respect to
Securities of such series, the Trustee shall be protected in withholding such
notice if and so long as the board of directors, the executive committee or a
trust committee of directors or Responsible Officers of the Trustee in good
faith determines that the withholding of such notice is in the interest of the
Holders of Securities of such series; and provided, further, that in the case of
any default of the character specified in Section 601(4) with respect to
Securities of such series, no such notice to Holders shall be given until at
least 30 days after the occurrence thereof. For the purpose of this Section, the
term "default" means any event which is, or after notice or lapse of time or
both would become, an Event of Default with respect to Securities of such
series.

          (c) whenever in the administration of this Indenture the Trustee shall
     deem it desirable that a matter be proved or established prior to taking,
     suffering or omitting any action hereunder, the Trustee (unless other
     evidence be herein specifically prescribed) may, in the absence of bad
     faith on its part, rely upon an Officers' Certificate;
 
          (d) the Trustee may consult with counsel and the written advice of
     such counsel or any Opinion of Counsel shall be full and complete
     authorization and protection in respect of any action taken, suffered or
     omitted by it hereunder in good faith and in reliance thereon;
 
          (e) the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request or direction
     of any of the Holders pursuant to this Indenture, unless such Holders shall
     have offered to the Trustee reasonable security or indemnity against the
     costs, expenses and liabilities which might be incurred by it in compliance
     with such request or direction;
 
          (f) the Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, coupon, other evidence of indebtedness or other
     paper or document, but the Trustee, in its discretion, may make such
     further inquiry or investigation into such facts or matters as it may see
     fit, and, if the Trustee shall determine to make such further inquiry or
     investigation, it shall be entitled to examine the books, records and
     premises of the Company, personally or by agent or attorney; and
 
          (g) the Trustee may execute any of the trusts or powers hereunder or
     perform any duties hereunder either directly or by or through agents or
     attorneys and the Trustee shall not be responsible for any misconduct or
     negligence on the part of any agent or attorney appointed with due care by
     it hereunder.
 
     SECTION 704. Not Responsible for Recitals or Issuance of Securities.
 
     The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and the Trustee assumes no responsibility for their correctness. The Trustee
makes no representations as to the validity or sufficiency of this Indenture or
of the Securities. The Trustee shall not be accountable for the use or
application by the Company of Securities or the proceeds thereof.

     SECTION 705. May Hold Securities.
 
     The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and coupons and, subject
to Sections 708 and 713, may otherwise deal with the Company with the same
rights it would have if it were not Trustee, Authenticating Agent, Paying Agent,
Security Registrar or such other agent.
 
     SECTION 706. Money Held in Trust.
 
     Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no

     SECTION 707. Compensation and Reimbursement.
 
     The Company agrees
 
          (1) to pay to the Trustee from time to time reasonable compensation
     for all services rendered by it hereunder (which completion shall not be
     limited by any provision of law in regard to the compensation of a trustee
     of an express trust);
 
          (2) except as otherwise expressly provided herein, to reimburse the
     Trustee upon its request for all reasonable expenses, disbursements and
     advances incurred or made by the Trustee in accordance with any provision
     of this Indenture (including the reasonable compensation and the reasonable
     expenses and disbursements of its agents and counsel), except any such
     expense, disbursement or advance as may be attributable to its negligence
     or bad faith; and
 
          (3) to indemnify the Trustee for, and to hold it harmless against, any
     loss, liability or expense incurred without negligence or bad faith on its
     part, arising out of or in connection with the acceptance or administration
     of the trust or trusts hereunder, including the costs and expenses of
     defending itself against any claim or liability in connection with the
     exercise or performance of any of its powers or duties hereunder.
 
     As security for the performance of the obligations of the Company under
this Section, the Trustee shall have a lien prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of, premium, if any, or interest, if any,
on, or any Additional Amounts with respect to, particular Securities.
 
     Any expenses and compensation for any services rendered by the Trustee
after the occurrence of an Event of Default specified in clause (5) or (6) of
Section 501 shall constitute expenses and compensation for services of
administration under all applicable federal or state bankruptcy, insolvency,
reorganization or other similar laws.
 
     The provisions of this Section shall survive the termination of this
Indenture.
 
     SECTION 708. Disqualification; Conflicting Interests.
 
     (a) If the Trustee has or shall acquire any conflicting interest, as
defined in this Section, with respect to the Securities of any series, it shall,
within 90 days after ascertaining that it has such conflicting interest, either
eliminate such conflicting interest or resign with respect to the Securities of
that series in the manner and with the effect hereinafter specified in this
Article.
 
     (b) In the event that the Trustee shall fail to comply with the provisions
of Subsection (a) of this Section with respect to the Securities of any series,
the Trustee shall, within 10 days after the expiration of such 90-day period,
transmit by mail to all Holders of Securities of that series, as their names and
addresses appear in the Security Register, notice of such failure.
 
                                       41
<PAGE>   49
 
     (c) For the purposes of this Section, the term "conflicting interest" shall
have the meaning specified in Section 310(b) of the Trust Indenture Act and the
Trustee shall comply with Section 310(b) of the Trust Indenture Act; provided,
that there shall be excluded from the operation of Section 310(b)(1) of the
Trust Indenture Act with respect to the Securities of any series the Indenture
dated as of                     between the Company and the Trustee relating to
the Company's subordinated debt securities, this Indenture with respect to the
Securities of any series other than that series and any other indenture or
indentures under which other securities, or certificates of interest or
participation in other securities, of the Company are outstanding, if the
requirements for such exclusion set forth in Section 310(b)(1) of the Trust
Indenture Act are met. For purposes of the preceding sentence, the optional
provision permitted by the second sentence of Section 310(b)(9) of the Trust
Indenture Act shall be applicable.
 
     SECTION 709. Corporate Trustee Required; Eligibility.
 
     There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America, any State thereof or the District of Columbia, authorized under such
laws to exercise corporate trust powers, having a combined capital and surplus
of at least $50,000,000 and subject to supervision or examination by federal or
state authority. If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.
 
     SECTION 710. Resignation and Removal; Appointment of Successor.
 
     (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 711.
 
     (b) The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 711 shall
not have been delivered to the resigning Trustee within 30 days after the giving
of such notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.
 
     (c) The Trustee may be removed at any time with respect to the Securities
of any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Company.
 
     (d) If at any time:
 
          (1) the Trustee shall fail to comply with Section 708(a) after written
     request therefor by the Company or by any Holder who has been a bona fide
     Holder of a Security for at least six months, or
 
          (2) the Trustee shall cease to be eligible under Section 709 and shall
     fail to resign after written request therefor by the Company or by any such
     Holder of Securities, or
 
          (3) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property
     shall be appointed or any public officer shall take charge or control of
     the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation,
 
then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (ii) subject to Section 614, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.
 
                                       42
<PAGE>   50
 
     (e) If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Company, by a Board Resolution,
shall promptly appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of
such series and that at any time there shall be only one Trustee with respect to
the Securities of any particular series) and such successor Trustee or Trustees
shall comply with the applicable requirements of Section 711. If, within one
year after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to the Securities of any series shall
be appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with the applicable requirements of Section
711, become the successor Trustee with respect to the Securities of such series
and to that extent supersede the successor Trustee appointed by the Company. If
no successor Trustee with respect to the Securities of any series shall have
been so appointed by the Company or the Holders and accepted appointment in the
manner required by Section 711, any Holder who has been a bona fide Holder of a
Security of such series for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to the Securities of such
series.
 
     (f) The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series by mailing
written notice of such event by first-class mail, postage prepaid, to all
Holders of Securities of such series as their names and addresses appear in the
Security Register. Each notice shall include the name of the successor Trustee
with respect to the Securities of such series and the address of its Corporate
Trust Services Division.
 
     SECTION 711. Acceptance of Appointment by Successor.
 
     (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request
of the Company or the successor Trustee, such retiring Trustee shall, upon
payment of its charges, execute and deliver an instrument transferring to such
successor Trustee all the rights, powers and trusts of the retiring Trustee and
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder.
 
     (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture, the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
 
                                       43
<PAGE>   51
 
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates.
 
     (c) Upon request of any such successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Trustee all such rights, powers and trusts referred to in
paragraph (a) or (b) of this Section, as the case may be.
 
     (d) No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified and eligible under
this Article.
 
     SECTION 712. Merger, Conversion, Consolidation or Succession to Business.
 
     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.
 
     SECTION 713. Preferential Collection of Claims Against Company.
 
     The Trustee shall comply with Section 311(a) of the Trust Indenture Act,
excluding any creditor relationship described in Section 311(b) of the Trust
Indenture Act. A Trustee who has resigned or been removed shall be subject to
Section 311(a) of the Trust Indenture Act to the extent indicated therein.
 
     SECTION 714. Appointment of Authenticating Agent.
 
     The Trustee may appoint an Authenticating Agent or Agents which shall be
authorized to act on behalf of the Trustee to authenticate Securities issued
upon original issue and upon exchange, registration of transfer or partial
redemption or pursuant to Section 306, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, or in the case of an Authenticating Agent with
respect to Securities issuable as Bearer Securities, under the laws of any
country in which such Bearer Securities may be offered, authorized under such
laws to act as Authenticating Agent, having a combined capital and surplus of
not less than $50,000,000 or equivalent amount expressed in a foreign currency
and subject to supervision or examination by federal or state authority or
authority of such country. If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Authenticating Agent shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time an Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, such Authenticating
Agent shall resign immediately in the manner and with the effect specified in
this Section.
 
     Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such
 
                                       44
<PAGE>   52
 
Authenticating Agent shall be a party, or any corporation succeeding to the
corporate agency or corporate trust business of an Authenticating Agent, shall
continue to be an Authenticating Agent, provided such corporation shall be
otherwise eligible under this Section, without the execution or filing of any
paper or any further act on the part of the Trustee or the Authenticating Agent.
 
     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate

Agent which shall be acceptable to the Company and shall mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders as their
names and addresses appear in the Security Register. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with
like effect as if originally named as an Authenticating Agent. No successor
Authenticating Agent shall be appointed unless eligible under the provisions of
this Section.
 
     The Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payments, subject to the provisions

Authenticating Agent hereunder, such Authenticating Agent shall also be
obligated: (i) to furnish to the Security Registrar promptly all information
necessary to enable the Security Registrar to maintain at all times an accurate
and current Security Register; and (ii) prior to authenticating any Security
denominated in a foreign currency, to ascertain from the Company the units of

     qualification of this Indenture under the Trust Indenture Act.
 
     SECTION 1002. Supplemental Indentures With Consent of Holders.

     SECTION 1101. Payment of Principal, Premium and Interest.
 
     The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of (and premium,

interest due on and Additional Amounts payable with respect to Bearer Securities
on or before Maturity shall be payable only upon presentation and surrender of
the several coupons for such interest installments, as are evidenced thereby as
they severally mature.
 
     SECTION 1102. Maintenance of Office or Agency.
 
     If Securities of a series are issuable only as Registered Securities, the
Company will maintain in each Place of Payment for any series of Securities an
office or agency where Securities of that series may be presented or surrendered
for payment, where Securities of that series may be surrendered for registration
of transfer or exchange and where notices and demands to or upon the Company in
respect of the Securities of that series and this Indenture may be served.

of Chicago, in the City of New York, which, on the date hereof, is located at 14
Wall Street, 8th Floor, New York, New York 10005. If Securities of a series are
issuable as Bearer Securities, the Company will maintain (A) in The Borough of
Manhattan, The City of New York, an office or agency where any Registered
Securities of that
 
                                       50
<PAGE>   58
 
series may be presented or surrendered for payment, where any Registered
Securities of that series may be surrendered for registration of transfer, where
Securities of that series may be surrendered for exchange for Registered
Securities, where notices and demands to or upon the Company in respect of the
Securities of that series and this Indenture may be served and where Bearer
Securities of that series and related coupons may be presented or surrendered
for payment in the circumstances described in the following paragraph (and not

Place of Payment for that series which is located outside the United States, an
office or agency where Bearer Securities of that series and related coupons may
be presented and surrendered for payment (including payment of any Additional
Amounts with respect to Bearer Securities of that series); provided however,
that if the Securities of that series are listed on the International Stock
Exchange of the United Kingdom and the Republic of Ireland Limited, the
Luxembourg Stock Exchange or any other stock exchange located outside the United
States and such stock exchange shall so require, the Company will maintain a
Paying Agent for the Securities of that series in London, Luxembourg or any
other required city located outside the United States, as the case may be, so
long as the Securities of that series are listed on such exchange, and (C)
subject to any laws or regulations applicable thereto, in a Place of Payment for
that series located outside the United States an office or agency where any
Registered Securities of that series may be surrendered for registration of
transfer, where Securities of that series may be surrendered for exchange and
where notices and demands to or upon the Company in respect of the Securities of
that series and this Indenture may be served. The Company will give prompt
written notice to the Trustee of the location, and any change in the location,
of such office or agency. If at any time the Company shall fail to maintain any
such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Services Division of the Trustee, except that
Bearer Securities of that series and the related coupons may be presented and
surrendered for payment (including payment of any Additional Amounts with
respect to Bearer Securities of that series) at the office of any Paying Agent
for such series located outside the United States, and the Company hereby
appoints the Trustee as its office or agency to receive such presentations,
surrenders, notices and demands.
 
     No payment of principal, premium or interest on, or Additional Amounts with
respect to, Bearer Securities shall be made at any office or agency of the
Company in the United States or by check mailed to any address in the United
States or by transfer to an account maintained with a bank located in the United
States, nor shall any payments be made in respect of Bearer Securities or
coupons appertaining thereto pursuant to the presentation to the Company or its
designated Paying Agents within the United States; provided, however, that, if
the Securities of a series are denominated and payable in Dollars, payment of
principal of and any premium and interest on any Bearer Security (including any
Additional Amounts payable on Securities of such series) shall be made at the
office of the Company's Paying Agent in The Borough of Manhattan, The City of
New York, if (but only if) payment in Dollars of the full amount of such
principal, premium, interest or Additional Amounts, as the case may be, at all
offices or agencies outside the United States maintained for the purpose by the
Company in accordance with this Indenture is illegal or effectively precluded by
exchange controls or other similar restrictions.
 
     The Company may also from time to time designate one or more other offices
or agencies where the Securities of one or more series may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency
in each Place of Payment for Securities of any series for such purposes. The
Company will give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency. The Company hereby designates the Corporate Trust Services Division of
the Trustee as one such office or agency of the Company in accordance with
Section 305.
 
     SECTION 1103. Money for Securities Payments to be Held in Trust.
 
     If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities and any coupons appertaining thereto, it will, on or
before each due date of the principal of (and premium, if any) or interest on or
any Additional Amounts with respect to any of the Securities of that series,
segregate and
 
                                       51
<PAGE>   59
 
hold in trust for the benefit of the Persons entitled thereto a sum sufficient
to pay the principal (and premium, if any) or interest so becoming due until
such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to
act.
 
     Whenever the Company shall have one or more Paying Agents for any series of
Securities and any related coupons appertaining thereto, the Company will, on or
before each due date of the principal of (and premium, if any) or interest on
any Securities of that series, deposit with a Paying Agent a sum sufficient to
pay the principal (and premium, if any) or interest so becoming due, such sum to
be held in trust for the benefit of the Persons entitled to such principal,
premium or interest, and (unless such Paying Agent is the Trustee) the Company
will promptly notify the Trustee of its action or failure so to act.
 
     The Company will cause each Paying Agent for any series of Securities other
than the Trustee to execute and deliver to the Trustee an instrument in which
such Paying Agent shall agree with the Trustee, subject to the provisions of
this Section, that such Paying Agent will:
 
          (1) hold all sums held by it for the payment of the principal of (and
     premium, if any), interest on or any Additional Amounts with respect to
     Securities of that series in trust for the benefit of the Persons entitled
     thereto until such sums shall be paid to such Persons or otherwise disposed
     of as herein provided;
 
          (2) give the Trustee notice of any default by the Company (or any
     other obligor upon the Securities of that series) in the making of any
     payment of principal (and premium, if any), interest on or any Additional
     Amounts with respect to the Securities of that series; and
 
          (3) at any time during the continuance of any such default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent.
 
     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which sums were held by the Company or such Paying
Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying
Agent shall be released from all further liability with respect to such money.
 
     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of (and premium, if any)
or interest on any Security of any series and remaining unclaimed for three
years after such principal (and premium, if any) or interest has become due and
payable shall, unless otherwise required by mandatory provisions of applicable
escheat, or abandoned or unclaimed property law, be paid to the Company on
Company Request, or (if then held by the Company) shall be discharged from such
trust; and the Holder of such Security and coupon appertaining thereto shall
thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in an Authorized Newspaper in
The Borough of Manhattan, The City of New York, notice that such money remains
unclaimed and that, after a date specified herein, which shall not be less than
30 days from the date of such publication, any unclaimed balance of such money
then remaining will, unless otherwise required by mandatory provisions of
applicable escheat, or abandoned or unclaimed property law, be repaid to the
Company.
 
     SECTION 1104. Existence.
 
     Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence.
 
     SECTION 1105. Maintenance of Properties.
 
     The Company will cause all properties used or useful in the conduct of its
business or the business of any Subsidiary to be maintained and kept in good
condition, repair and working order and supplied with all
 
                                       52
<PAGE>   60
 
necessary equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided,
however, that nothing in this Section shall prevent that Company from
discontinuing the operation or maintenance of any of such properties if such
discontinuance is, in the judgment of the Company, desirable in the conduct of
its business or the business of any Subsidiary and not disadvantageous in any
material respect to the Holders.
 
     SECTION 1106. Limitation on Sale/Leaseback Transactions.
 
     The Company shall not, and shall not permit any Restricted Subsidiary to,
enter into any arrangement providing for the leasing by the Company or any
Restricted Subsidiary for a period of more than three years, of any real or
tangible personal property, which property has been or is to be sold or
transferred by the Company or such Restricted Subsidiary to such Person in
contemplation of such leasing (a "Sale/Leaseback Transaction") with any Person
(other than the Company or a Restricted Subsidiary) unless:
 
          (a) the Company or such Restricted Subsidiary would be entitled to
     incur Indebtedness, in a principal amount equal to the Attributable
     Indebtedness with respect to such Sale/Leaseback Transaction, secured by a
     Lien on the property subject to such Sale/Leaseback Transaction pursuant to
     Section 1107 without equally and ratably securing the Securities pursuant
     to such Section;
 
          (b) after the Issue Date and within a period commencing six months
     prior to the consummation of such Sale/Leaseback Transaction and ending six
     months after the consummation thereof, the Company or such Restricted
     Subsidiary shall have expended for property used or to be used in the
     ordinary course of business of the Company and the Restricted Subsidiaries
     (including amounts expended for the exploration, drilling or development
     thereof, and for additions, alterations, repairs and improvements thereto)
     an amount equal to all or a portion of the Net Proceeds of such
     Sale/Leaseback Transaction and the Company shall have elected to designate
     such amount as a credit against such Sale/Leaseback Transaction (with any
     such amount not being so designated to be applied as set forth in clause
     (d) below); or
 
          (c) the Company, during the 12-month period after the effective date
     of such Sale/Leaseback Transaction, shall have applied to the voluntary
     defeasance or retirement of Securities or any Pari Passu Indebtedness an
     amount equal to the greater of the Net Proceeds of the sale or transfer of
     the property leased in such Sale/Leaseback Transaction and the fair value,
     as determined by the Board of Directors of the Company, of such property at
     the time of entering into such Sale/Leaseback Transaction (in either case
     adjusted to reflect the remaining term of the lease and any amount expended
     by the Company as set forth in clause (b) above), less an amount equal to
     the principal amount of Securities and Pari Passu Indebtedness voluntarily
     defeased or retired by the Company within such 12-month period and not
     designated as a credit against any other Sale/Leaseback Transaction entered
     into by the Company or any Subsidiary during such period.
 
     SECTION 1107. Limitation on Liens
 
     No provision of this Indenture or the Securities shall in any way restrict
or prevent the Company or any Restricted Subsidiary from issuing, assuming,
guaranteeing or otherwise incurring any Indebtedness, provided, however, that
the Company shall not, and shall not permit any Restricted Subsidiary to, issue,
assume or guarantee any Indebtedness for borrowed money secured by any Lien on
any property or asset now owned or hereafter acquired by the Company or such
Restricted Subsidiary without making effective provision whereby any and all
Securities then or thereafter outstanding will be secured by a Lien equally and
ratably with any and all other obligations thereby secured for so long as any
such obligations shall be so secured. Notwithstanding the foregoing, the Company
or any Restricted Subsidiary may, without so securing the Securities, issue,
assume or guarantee Indebtedness secured by the following Liens:
 
          (a) Liens existing on the Issue Date or provided for under the terms
     of agreements existing on the Issue Date;
 
                                       53
<PAGE>   61
 
          (b) Liens on property securing (i) all or any portion of the cost of
     exploration, drilling or development of such property, (ii) all or any
     portion of the cost of acquiring, constructing, altering, improving or
     repairing any property or assets, real or personal, or improvements used or
     to be used in connection with such property or (iii) Indebtedness incurred
     by the Company or any Restricted Subsidiary to provide funds for the
     activities set forth in clauses (i) and (ii) above;
 
          (c) Liens securing Indebtedness owed by a Restricted Subsidiary to the
     Company or to any other Restricted Subsidiary;
 
          (d) Liens on the property of any Person existing at the time such
     Person becomes a Subsidiary of the Company and not incurred as a result of
     (or in connection with or in anticipation of) such Person becoming a
     Subsidiary of the Company, provided that such Liens do not extend to or
     cover any property or assets of the Company or any of its Subsidiaries
     other than the property so acquired;
 
          (e) Liens on any property securing (i) Indebtedness incurred in
     connection with the construction, installation or financing of pollution
     control or abatement facilities or other forms of industrial revenue bond
     financing or (ii) Indebtedness issued or guaranteed by the United States or
     any State thereof or any department, agency or instrumentality of either;
 
          (f) any Lien on any asset securing Non-Recourse Indebtedness of the
     Company or any Restricted Subsidiary or on any asset of Union Texas East
     Kalimantan Limited securing Joint Venture Indebtedness;
 
          (g) any Lien extending, renewing or replacing (or successive
     extensions, renewals or replacements of) any Lien of any type permitted
     under clauses (a) through (f) above, provided that such Lien extends to or
     covers only the property that is subject to the Lien being extended,
     renewed or replaced;
 
          (h) any Ordinary Course Lien arising, but only so long as continuing,
     in the ordinary course of business of the Company and the Restricted
     Subsidiaries; or
 
          (i) Liens (exclusive of any Lien of any type otherwise permitted under
     clauses (a) through (h) above) securing Indebtedness of the Company or any
     Restricted Subsidiary in an aggregate principal amount which, together with
     the aggregate amount of Attributable Indebtedness deemed to be outstanding
     in respect of all Sale/Leaseback Transactions entered into pursuant to
     clause (a) of Section 1106 (exclusive of any such Sale/Leaseback
     Transactions otherwise permitted under clauses (a) through (h) above), does
     not at the time such Indebtedness is incurred exceed 10% of the
     Consolidated Net Worth of the Company (as shown in the most recent audited
     consolidated balance sheet of the Company and its Subsidiaries).
 
     Notwithstanding the foregoing, nothing in this Section 1107 shall be deemed
to prohibit or otherwise limit the following types of transactions:
 
          (i) the sale, granting of Liens with respect to, or other transfer of,
     crude oil, natural gas or other petroleum hydrocarbons in place for a
     period of time until, or in an amount such that, the transferee will
     realize therefrom a specified amount (however determined) of money or of
     such crude oil, natural gas or other petroleum hydrocarbons;
 
          (ii) the sale or other transfer of any other interest in property of
     the character commonly referred to as a production payment, overriding
     royalty, forward sale or similar interest; or
 
          (iii) the granting of Liens required by any contract or statute in
     order to permit the Company or any Restricted Subsidiary to perform any
     contract or subcontract made by it with or at the request of the United
     States or any State thereof or of any foreign government or any department,
     agency, organization or instrumentality thereof, or to secure partial,
     progress, advance or other payments to the Company or any Restricted
     Subsidiary by such governmental unit pursuant to the provisions of any
     contract or statute.
 
                                       54
<PAGE>   62
 
     SECTION 1108. Payment of Taxes and Other Claims.
 
     The Company will pay or discharge or cause to be paid or discharged, before
the same shall become delinquent, (1) all material taxes, assessments and
governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income, profits or property of the Company or any Subsidiary, and (2)
all material lawful claims for labor, materials and supplies which, if unpaid,
might by law become a lien upon the property of the Company or any Subsidiary;
provided, however, that the Company shall not be required to pay or discharge or
cause to be paid or discharged any such tax, assessment, charge or claim whose
amount, applicability or validity is being contested in good faith by
appropriate proceedings.
 
     SECTION 1109. Statement by Officers as to Default.
 
     The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year of the Company ending after the date hereof so long as any
Security is outstanding hereunder, an Officers' Certificate, stating that a
review of the activities of the Company during such year and of performance
under this Indenture has been made under the supervision of the signers thereof
and whether or not to the best of their knowledge, based upon such review, the
Company is in default in the performance, observance or fulfillment of any of
its covenants and other obligations under this Indenture, and if the Company
shall be in default, specifying each such default known to them and the nature
and status thereof. One of the officers signing the Officers' Certificate
delivered pursuant to this Section 1109 shall be the principal executive,
financial or accounting officer of the Company.
 
     For purposes of this Section, such compliance shall be determined without
regard to any period of grace or requirement of notice provided under this
Indenture.
 
     SECTION 1110. Waiver of Certain Covenants.
 
     The Company may omit in any particular instance to comply with any covenant
or condition set forth in Sections 1104 to 1108, inclusive, or any covenant
added for the benefit of any series of Securities as contemplated by Section 301
(unless otherwise specified pursuant to Section 301) if before or after the time
for such compliance the Holders of a majority in principal amount of the
Outstanding Securities of all series affected by such omission (acting as one
class) shall, by Act of such Holders, either waive such compliance in such
instance or generally waive compliance with such covenant or condition, but no
such waiver shall extend to or affect such covenant, or condition except to the
extent so expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the duties of the Trustee in respect of any such
covenant or condition shall remain in full force and effect.
 
     SECTION 1111. Additional Amounts.
 
     If the Securities of a series provide for the payment of Additional
Amounts, the Company will pay to the Holder of any Security of such series or
any coupon appertaining thereto Additional Amounts as provided therein. Whenever
in this Indenture there is mentioned, in any context, the payment of the
principal of or any premium or interest on, or in respect of, any Security of
any series or payment of any related coupon or the net proceeds received on the
sale or exchange of any Security of any series, such mention shall be deemed to
include mention of the payment of Additional Amounts provided for in this
Section to the extent that, in such context, Additional Amounts are, were or
would be payable in respect thereof pursuant to the provisions of this Section
and express mention of the payment of Additional Amounts (if applicable) in any
provisions hereof shall not be construed as excluding Additional Amounts in
those provisions hereof where such express mention is not made.
 
     If the Securities of a series provide for the payment of Additional
Amounts, at least 10 days prior to the first Interest Payment Date with respect
to that series of Securities (or if the Securities of that series will not bear
interest prior to Maturity, the first day on which a payment of principal and
any premium is made), and at least 10 days prior to each date of payment of
principal and any premium or interest if there has been any change with respect
to the matters set forth in the below-mentioned Officers' Certificate, the
Company shall furnish the Trustee and the Company's principal Paying Agent or
Paying Agents, if other than the Trustee,
 
                                       55
<PAGE>   63
 
with an Officers' Certificate instructing the Trustee and such Paying Agent or
Paying Agents whether such payment of principal of and any premium or interest
on the Securities of that series shall be made to Holders of Securities of that
series or any related coupons who are United States Aliens without withholding
for or on account of any tax, assessment or other governmental charge described
in the Securities of that series. If any such withholding shall be required,
then such Officers' Certificate shall specify by country the amount, if any,
required to be withheld on such payments to such Holders of Securities or
coupons and the Company will pay to such Paying Agent the Additional Amounts
required by this Section. The Company covenants to indemnify the Trustee and any
Paying Agent for, and to hold them harmless against any loss, liability or
expense reasonably incurred without negligence or bad faith on their part
arising out of or in connection with actions taken or omitted by any of them in
reliance on any Officers' Certificate furnished pursuant to this Section.
 
                                 ARTICLE TWELVE
 
                            REDEMPTION OF SECURITIES
 
     SECTION 1201. Applicability of Article.
 
     Securities of any series which are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified as contemplated by Section 301 for Securities of any series) in
accordance with this Article.
 
     SECTION 1202. Election to Redeem; Notice to Trustee.
 
     The election of the Company to redeem any Securities shall be evidenced by
a Board Resolution. In case of any redemption at the election of the Company of
less than all the Securities of any series, the Company shall, at least 60 days
prior to the Redemption Date fixed by the Company (unless a shorter notice shall
be satisfactory to the Trustee), notify the Trustee of such Redemption Date and
of the principal amount of Securities of such series to be redeemed. In the case
of any redemption of Securities prior to the expiration of any restriction on
such redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction.
 
     SECTION 1203. Selection by Trustee of Securities to be Redeemed.
 
     If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, pro rata or by lot or by such
other method as the Trustee shall deem fair and appropriate and which may
provide for the selection for redemption of portions (equal to the minimum
authorized denomination for Securities of that series or any integral multiple
thereof) of the principal amount of Securities of such series of a denomination
larger than the minimum authorized denomination for Securities of that series or
of the principal amount of global Securities of such series.
 
     The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption and, in the case of any Securities selected for partial
redemption, the principal amount thereof to be redeemed.
 
     For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion
of the principal amount of such Securities which has been or is to be redeemed.
 
                                       56
<PAGE>   64
 
     SECTION 1204. Notice of Redemption.
 
     Notice of redemption shall be given in the manner provided in Section 107
to each Holder of Securities to be redeemed not less than 30 nor more than 60
days prior to the Redemption Date.
 
     All notices of redemption shall state:
 
          (1) the Redemption Date;
 
          (2) the Redemption Price, including each component thereof;
 
          (3) if less than all the Outstanding Securities of any series are to
     be redeemed, the identification (and, in the case of partial redemption,
     the principal amounts) of the particular Securities to be redeemed;
 
          (4) that on the Redemption Date the Redemption Price will become due
     and payable upon each such Security to be redeemed and, if applicable, that
     interest thereon will cease to accrue on and after said date;
 
          (5) the place or places where such Securities, together in the case of
     Bearer Securities with all coupons appertaining thereto, are to be
     surrendered for payment of the Redemption Price;
 
          (6) that the redemption is for a sinking fund, if such is the case;
 
          (7) that, unless otherwise specified in such notice, Bearer Securities
     of any series, if any, surrendered for redemption must be accompanied by
     all coupons appertaining thereto maturing subsequent to the date fixed for
     redemption or the amount of any such missing coupon or coupons will be
     deducted from the Redemption Price or security or indemnity satisfactory to
     the Company, the Trustee and any Paying Agent is furnished;
 
          (8) if Bearer Securities of any series are to be redeemed and any
     Registered Securities of such series are not to be redeemed, and if such
     Bearer Securities may be exchanged for Registered Securities not subject to
     redemption on such Redemption Date pursuant to Section 305 or otherwise,
     the last date, as determined by the Company, on which such exchanges may be
     made;
 
          (9) the aggregate principal amount of Securities being redeemed; and
 
          (10) the "CUSIP" number of the Securities, if applicable.
 
     A notice of redemption as contemplated by Section 107 need not identify
particular Registered Securities to be redeemed. Notice of redemption of
Securities to be redeemed at the election of the Company shall be given by the
Company or, at the Company's request, by the Trustee in the name and at the
expense of the Company.
 
     SECTION 1205. Deposit of Redemption Price.
 
     On or before any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1103) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, and any Additional
Amounts with respect to, all the Securities which are to be redeemed on that
date.
 
     SECTION 1206. Securities Payable on Redemption Date.
 
     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest and the coupons for such
interest appertaining to any Bearer Securities so to be redeemed, except to the
extent provided below, shall be redeemed. Upon surrender of any such Security
for redemption in accordance with said notice, together with all coupons
appertaining thereto, if
 
                                       57
<PAGE>   65
 
any, appertaining thereto maturing after the Redemption Date, such Security
shall be paid by the Company at the Redemption Price, together with accrued
interest (and any Additional Amounts) to the Redemption Date; provided, however,
that all payments on Bearer Securities shall be made only in the manner provided
in Section 1102 for payments on Bearer Securities; and provided further, that
installments of interest whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such Securities, or one or more
Predecessor Securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of Section
307.
 
     If any Bearer Security surrendered for redemption shall not be accompanied
by all appurtenant coupons appertaining thereto maturing after the Redemption
Date, such Security may be paid after deducting from the Redemption Price an
amount equal to the face amount of all such missing coupons appertaining
thereto, or the surrender of such missing coupon or coupons appertaining thereto
may be waived by the Company and the Trustee if there be furnished to them such
security or indemnity as they may require to save each of them and any Paying
Agent harmless. If thereafter the Holder of such Security shall surrender to the
Trustee or any Paying Agent any such missing coupon in respect of which a
deduction shall have been made from the Redemption Price, such Holder shall be
entitled to receive the amount so deducted; provided, however, that interest
(and any Additional Amounts with respect thereto) represented by coupons
appertaining thereto shall be payable only at an office or agency located
outside the United States (except as otherwise provided in Section 1102) and,
unless otherwise specified as contemplated by Section 301, only upon
presentation and surrender of those coupons appertaining thereto.
 
     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal (and premium, if any) shall, until paid,
bear interest from the Redemption Date at the rate prescribed therefor in the
Security or, in the case of Original Issue Discount Securities, the Securities'
Yield to Maturity.
 
     SECTION 1207. Securities Redeemed in Part.
 
     Any Registered Security which is to be redeemed only in part shall be
surrendered at a Place of Payment therefor (with, if the Company or the Trustee
so requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof
or his attorney duly authorized in writing), and the Company shall execute, and
the Trustee shall authenticate and deliver to the Holder of such Security
without service charge, a new Registered Security or Securities of the same
series and Stated Maturity, of any authorized denomination as requested by such
Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered.
 
     SECTION 1208. Purchase of Securities.
 
     Unless otherwise specified as contemplated by Section 301, the Company and
any Affiliate of the Company may at any time purchase or otherwise acquire
Securities or coupons appertaining thereto in the open market or by private
agreement; provided that purchases or other acquisitions of Bearer Securities or
coupons appertaining thereto by the Company or any Affiliate of the Company may
be made only outside the United States, and payments therefor may be made only
upon surrender of such Bearer Securities or coupons appertaining thereto at a
location outside the United States and only in the manner provided for payments
on Bearer Securities in Section 1102. Such acquisition shall not operate as or
be deemed for any purpose to be a redemption of the indebtedness represented by
such Securities or coupons appertaining thereto. Any Securities or coupons
appertaining thereto purchased or acquired by the Company may be delivered to
the Trustee and, upon such delivery, the indebtedness represented thereby shall
be deemed to be satisfied. Section 309 shall apply to all Securities and coupons
so delivered.

                                 SINKING FUNDS
 
     SECTION 1301. Applicability of Article.
 
     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.
 
     The minimum amount of any sinking fund payment provided for by the terms of
Securities of any series is herein referred to as a "mandatory sinking fund
payment", and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment." Unless otherwise provided by the terms of Securities of any
series, the cash amount of any sinking fund payment may be subject to reduction
as provided in Section 1302. Each sinking fund payment shall be applied to the
redemption of Securities of any series as provided for by the terms of
Securities of such series.
 
     SECTION 1302. Satisfaction of Sinking Fund Payments with Securities.
 
     The Company (1) may deliver Outstanding Securities of a series (other than
any previously called for redemption), together in the case of any Bearer
Securities of such series with all unmatured coupons appertaining thereto, and
(2) may apply as a credit Securities of a series which have been redeemed either

through the application of permitted optional sinking fund payments pursuant to
the terms of such Securities, in each case in satisfaction of all or any part of
any sinking fund payment with respect to the Securities of such series required

of such series; provided that such Securities have not been previously so

and at such place in Houston, Texas, in The Borough of Manhattan, The City of
New York, in London or in any other location, as the Trustee shall determine.
Notice of every meeting of Holders of Securities of any series, setting forth

to call a meeting of the Holders of Securities of such series for any purpose
specified in Section 1401, by written request setting forth in reasonable detail
the action proposed to be taken at the meeting, and the Trustee shall not have
made the first publication of the notice of such meeting within 30 days after
receipt of such request or shall not thereafter proceed to cause the meeting to

     SECTION 1404. Quorum Action.
 
     The Persons entitled to vote a majority in aggregate principal amount of

of Holders of Securities of such series. In the absence of a quorum within 30

In any other case, the meeting may be adjourned for a period of not less than 10

adjourned meeting shall state expressly that Persons entitled to vote a majority
in principal amount of the Outstanding Securities of such series shall

specified in Section 105 or by having the signature of the person executing the
proxy witnessed or guaranteed by any trust company, bank or banker authorized by
Section 105 to certify to the holding of Bearer Securities. Such regulations may
provide that written instruments appointing proxies, regular on their face, may
be presumed valid and genuine without the proof specified in Section 105 or
other proof.
 
     (b) The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of Securities as provided in Section 1402(b), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall appoint a temporary chairman. A permanent chairman and
a permanent secretary of the meeting shall be elected by vote of the Persons
entitled to vote a majority in aggregate principal amount of the Outstanding
Securities of such series represented at the meeting.
 
     (c) At any meeting each Holder of a Security of such series and each proxy
shall be entitled to one vote for each $1,000 principal amount of the
Outstanding Securities of such series held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any
Security challenged as not Outstanding and ruled by the chairman of the meeting
to be not Outstanding. The chairman of the meeting shall have no right to vote,
except as a Holder of a Security of such series or as a proxy.
 
     (d) Any meeting of Holders of Securities of any series duly called pursuant
to Section 1402 at which a quorum is present may be adjourned from time to time
by Persons entitled to vote a majority in aggregate principal amount of the
Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.
 
     SECTION 1406. Counting Votes and Recording Action of Meetings.

Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them. The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in duplicate of all votes cast at the meeting. A record, at least in
duplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be
attached to such record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that such notice was given as provided in Section 1402 and, if
applicable, Section 1404. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

                               (THE "SECURITIES")
 
     This is to certify that as of the date hereof, and except as set forth
below, the above-captioned Securities that are held by the undersigned or held
by you for the account of the undersigned (i) are owned by person(s) that are

either case (A) or (B), each such United States financial institution hereby
certifies, on its own behalf or through its agent that it will comply with the

States or foreign financial institution(s) for purposes of resale during the
restricted period (as defined in U.S. Treasury Regulations Section 1.163-
5(c)(2)(i)(D)(7)) and in addition if the owner of the Securities is a United
States or foreign financial institution described in clause (iii) above (whether
or not also described in clause (i) or (ii)) this is to further certify that
such financial institution has not acquired the Securities for purposes of
resale directly or indirectly to a United States person or to a person within
the United States or its possessions.
 
     If the Securities are of the category contemplated in Section 230.903(c)(3)
of Regulation S under the Securities Act of 1933, as amended (the "Act"), then
this is also to certify that, except as set forth below, (i) in the case of debt

(b) U.S. person(s) who purchased the Securities in transactions which did not
require registration under the Act; or (ii) in the case of equity securities,
the Securities are owned by (x) non-U.S. person(s) (and such person(s) are not

require registration under the Act. If this certification is being delivered in
connection with the exercise of warrants pursuant to Section 230.902(m) of
Regulation S under the Act, then this is further to certify that, except as set
forth below, the Securities are being exercised by and on behalf of non-U.S.

by you for our account in accordance with your operating procedures if any
applicable statement herein is not correct on such date, and in the absence of

such date.
 
     This certification excepts and does not relate to $          of such
interest in the above Securities in respect of which we are not able to certify
and as to which we understand exchange and delivery of definitive Securities
(or, if relevant, exercise of any rights or collection of any interest) cannot
be made until we do so certify.

                      UNION TEXAS PETROLEUM HOLDINGS, INC.
 
                          8 3/8% SENIOR NOTE DUE 2005
 
     1. Interest. Union Texas Petroleum Holdings, Inc., a Delaware corporation
(the "Company"), promises to pay interest on the principal amount of this
Security at 8 3/8% per annum from March 23, 1995 until maturity. The Company
will pay interest semiannually on September 15 and March 15 of each year (each
an "Interest Payment Date"), or if any such day is not a Business Day, on the
next succeeding Business Day. Interest on the Securities will accrue from the
most recent Interest Payment Date on which interest has been paid or, if no
interest has been paid, from March 23, 1995; provided, that if there is no
existing Default in the payment of interest, and if this Security is
authenticated between a record date referred to on the face hereof and the next
succeeding Interest Payment Date, interest shall accrue from such next
succeeding Interest Payment Date; provided, further, that the first Interest
Payment Date shall be September 15, 1995. The Company shall pay interest on
overdue principal and premium, if any, from time to time on demand at a rate
equal to the interest rate then in effect; it shall pay interest on overdue
installments of interest (without regard to any applicable grace periods) from
time to time on demand at the same rate to the extent lawful. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.
 
     2. Method of Payment. The Company will pay interest on the Securities
(except defaulted interest) to the Persons who are registered Holders of
Securities at the close of business on the record date next preceding the
Interest Payment Date, even if such Securities are canceled after such record
date and on or before such Interest Payment Date. The Holder must surrender this
Security to a Paying Agent to collect principal payments. The Company will pay
the principal of, premium, if any, and interest on the Securities in money of
the United States of America that at the time of payment is legal tender for
payment of public and private debts. The Company, however, may pay such amounts
by check payable in such money. It may mail an interest check to a Holder's
registered address.
 
     3. Ranking and Guarantees. The Securities will be senior unsecured
obligations of the Company. The Company's obligations to pay principal, premium,
if any, and interest with respect to the Securities are unconditionally
guaranteed on a joint and several basis (the "Guarantees") by the guarantors
(the "Guarantors") parties to the Indenture. Each of the Guarantees will be an
unsecured obligation of the Guarantor providing such Guarantee. Certain
limitations to the obligations of the Guarantors are set forth in further detail
in the Indenture. References herein to the Indenture or the Securities shall be
deemed also to refer to the Guarantees set forth in the Indenture except where
the context otherwise requires.
 
     4. Paying Agent and Registrar. Initially, The First National Bank of
Chicago, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Company may change any Paying Agent, Registrar or co-registrar
without notice to any Holder. The Company may act in any such capacity.
 
     5. Indenture. The Company issued the Securities under an Indenture dated as
of March 15, 1995 (the "Indenture") among the Company, the Guarantors and the
Trustee. The terms of the Securities include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of
1939, as amended (15 U.S. Code sec.sec. 77aaa-77bbbb) as in effect on the date
of execution of the Indenture. The Securities are subject to all such terms, and
Holders are referred to the Indenture and such Act for a statement of such
terms. The Securities are unsecured general obligations of the Company limited
to $125,000,000 in aggregate principal amount.
 
     6. Optional Redemption. The Securities may be redeemed at any time, at the
option of the Company, in whole or from time to time in part, at a price equal
to 100% of their principal amount plus accrued and unpaid interest, if any, to
the Redemption Date plus the Make-Whole Premium, if any (the "Redemption
Price").
<PAGE>   3
 
                             SPECIMEN FORM OF NOTE
 
The amount of the Make-Whole Premium with respect to any Security (or portion
thereof) to be redeemed will be equal to the excess, if any, of:
 
          (i) the sum of the present values, calculated as of the Redemption
     Date, of:
 
             (A) each interest payment that, but for such redemption, would have
        been payable on the Security (or portion thereof) being redeemed on each
        Interest Payment Date occurring after the Redemption Date (excluding any
        accrued interest for the period prior to the Redemption Date); and
 
             (B) the principal amount that, but for such redemption, would have
        been payable at the final maturity of the Security (or portion thereof)
        being redeemed;
 
     over
 
          (ii) the principal amount of the Security (or portion thereof) being
     redeemed.
 
The present values of interest and principal payments referred to in clause (i)
above will be determined in accordance with generally accepted principles of
financial analysis. Such present values will be calculated by discounting the
amount of each payment of interest or principal from the date that each such
payment would have been payable, but for the redemption, to the Redemption Date
at a discount rate equal to the Treasury Yield. The Make-Whole Premium will be
calculated by an independent investment banking institution of national standing
appointed by the Company; provided, that if the Company fails to make such
appointment at least 10 business days prior to the Redemption Date, or if the
institution so appointed is unwilling or unable to make such calculation, such
calculation will be made by Goldman, Sachs & Co. or, if such firm is unwilling
or unable to make such calculation, by an independent investment banking
institution of national standing appointed by the Trustee (in any such case, an
"Independent Investment Banker").
 
     For purposes of determining the Make-Whole Premium, "Treasury Yield" means
a rate of interest per annum equal to the weekly average yield to maturity of
United States Treasury Notes that have a constant maturity that corresponds to
the remaining term to maturity of the Securities, calculated to the nearest
1/12 of a year (the "Remaining Term"). The Treasury Yield will be determined as
of the third business day immediately preceding the applicable Redemption Date.
The weekly average yields of United States Treasury Notes will be determined by
reference to the most recent statistical release published by the Federal
Reserve Bank of New York and designated "H.15(519) Selected Interest Rates" or
any successor release (the "H.15 Statistical Release"). If the H.15 Statistical
Release sets forth a weekly average yield for United States Treasury Notes
having a constant maturity that is the same as the Remaining Term, then the
Treasury Yield will be equal to such weekly average yield. In all other cases,
the Treasury Yield will be calculated by interpolation, on a straight-line
basis, between the weekly average yields on the United States Treasury Notes
that have a constant maturity closest to and greater than the Remaining Term and
the United States Treasury Notes that have a constant maturity closest to and
less than the Remaining Term (in each case as set forth in the H.15 Statistical
Release). Any weekly average yields so calculated by interpolation will be
rounded to the nearest 1/100 of 1%, with any figure of 1/200% or above being
rounded upward. If weekly average yields for United States Treasury Notes are
not available in the H.15 Statistical Release or otherwise, then the Treasury
Yield will be calculated by interpolation of comparable rates selected by the
Independent Investment Banker.
 
     Periodic interest installments with respect to which the Interest Payment
Date is on or prior to any Redemption Date will be payable to the Holders of
record at the close of business on the relevant record dates referred to herein,
all as provided in the Indenture.
 
     Notice of redemption will be mailed at least 30 days but not more than 60
days before the Redemption Date to each Holder of Securities to be redeemed at
his registered address. Securities in denominations larger than $1,000 may be
redeemed in part but only in whole multiples of $1,000, provided that if all the
Securities of a Holder are to be redeemed, the entire outstanding amount of
Securities held by such Holder, even if not a
<PAGE>   4
 
                             SPECIMEN FORM OF NOTE
 
whole multiple of $1,000, will be redeemed. On and after the Redemption Date
interest will cease to accrue on Securities or on the portions thereof called
for redemption, as the case may be.
 
     7. Denominations, Transfer, Exchange. The Securities are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of Securities may be registered and Securities may be exchanged as
provided in the Indenture. The Registrar and the Trustee may require a Holder,
among other things, to furnish appropriate endorsements and transfer documents
and to pay any taxes and fees required by law or permitted by the Indenture. The
Registrar need not exchange or register the transfer of any Security or portion
of a Security selected for redemption. Also, it need not exchange or register
the transfer of any Securities for a period of 15 days before a selection of
Securities to be redeemed or during the period between a record date and the
corresponding Interest Payment Date.
 
     8. Persons Deemed Owners. The registered Holder of a Security shall be
treated as its owner for all purposes.
 
     9. Amendments and Waivers. Subject to certain exceptions and limitations,
the Indenture or the Securities may be amended or supplemented with the consent
of the Holders of at least a majority in principal amount of the then
outstanding Securities, and any existing Default under, or compliance with any
provision of, the Indenture may be waived (other than any continuing Default or
Event of Default in the payment of the principal of or premium, if any, or
interest on the Securities) by the Holders of at least a majority in principal
amount of the Securities then outstanding in accordance with the terms of the
Indenture. Without the consent of any Holder, the Company, the Guarantors and
the Trustee may amend or supplement the Indenture or the Securities to evidence
the assumption by any successor to the Company of the covenants in the Indenture
and the Securities; to add to the covenants of the Company for the benefit of
the Holders; to add any additional Events of Default with respect to the
Securities; to provide for uncertificated Securities in addition to or in place
of certificated Securities and to provide for certificated Securities in
addition to or in place of uncertificated Securities; to make any change that
does not adversely affect any Security; to establish the form or terms of
Securities; to permit or facilitate the defeasance or discharge of any series of
Securities; to provide for the acceptance of appointment by a successor Trustee
and the administration of the trusts by more than one Trustee; to provide for
Guarantees of the Securities or to reflect the release of any Guarantor from its
Guarantee, or the addition of any Subsidiary of the Company as a Guarantor; to
cure any ambiguity, omission, defect or inconsistency; or to comply with the
qualification of the Indenture under the Trust Indenture Act of 1939, as
amended.
 
     The right of any Holder to participate in any consent required or sought
pursuant to any provision of the Indenture (and the obligation of the Company to
obtain any such consent otherwise required from such Holder) may be subject to
the requirement that such Holder shall have been the Holder of record of any
Securities with respect to which such consent is required or sought as of a date
identified by the Trustee in a notice furnished to Holders in accordance with
the terms of the Indenture.
 
     Without the consent of each Holder affected, the Company may not (i) reduce
the percentage in principal amount of Securities whose Holders must consent to
an amendment, supplement or waiver, (ii) reduce the rate of or change the time
for payment of interest, including default interest, on any Security, (iii)
reduce the principal of or change the fixed maturity of any Security or alter
the premium or other provisions with respect to redemption, (iv) make any
Security payable in money other than that stated in the Security, (v) impair the
right to institute suit for the enforcement of any payment of principal of, or
premium, if any, or interest on any Security, (vi) reduce the percentage in
principal amount of Securities necessary to waive compliance with certain
provisions of the Indenture or (vii) waive a continuing Default or Event of
Default in the payment of principal of or premium, if any, or interest on the
Securities.
 
     10. Defaults and Remedies. Events of Default include: default in payment of
interest on the Securities for 30 days; default in payment of principal of or
premium, if any, on the Securities; failure by the Company or any Guarantor for
60 days after written notice by the Trustee or by the Holders of at least 25% of
the aggregate principal amount of the Securities then outstanding to it to
comply with any of its other covenants or
<PAGE>   5
 
                             SPECIMEN FORM OF NOTE
 
agreements in the Indenture, the Guarantees or the Securities; the acceleration
of the maturity of any Indebtedness of the Company or any Restricted Subsidiary
(other than the Securities or any Non-Recourse Indebtedness) that has an
outstanding principal amount of $20 million or more individually or in the
aggregate; a default in the payment of principal or interest in respect of any
Indebtedness of the Company or any Restricted Subsidiary (other than the
Securities or any Non-Recourse Indebtedness) having an outstanding principal
amount of $20 million or more individually or in the aggregate, and such default
shall be continuing for a period of 30 days without the Company or such
Restricted Subsidiary, as the case may be, effecting a cure of such default; or
certain events involving bankruptcy, insolvency or reorganization of the Company
or any Restricted Subsidiary. If an Event of Default occurs and is continuing,
the Trustee or the Holders of at least 25% in principal amount of the then
outstanding Securities may declare the principal of, and premium, if any, and
interest on all the Securities to be immediately due and payable, except that in
the case of an Event of Default arising from certain events of bankruptcy,
insolvency or reorganization of the Company or any Restricted Subsidiary, all
outstanding Securities become due and payable immediately without further action
or notice. The amount due and payable upon the acceleration of any Security is
equal to 100% of the principal amount thereof plus accrued interest to the date
of payment. Holders may not enforce the Indenture or the Securities except as
provided in the Indenture. The Trustee may require indemnity reasonably
satisfactory to it before it enforces the Indenture or the Securities. Subject
to certain limitations, Holders of a majority in principal amount of the then
outstanding Securities may direct the Trustee in its exercise of any trust or
power. The Trustee may withhold from Holders notice of any continuing default
(except a default in payment of principal or interest) if it determines that
withholding notice is in their interests. The Company must furnish an annual
compliance certificate to the Trustee.
 
     11. Trustee Dealings with Company and Guarantors. The Trustee, in its
individual or any other capacity, may make loans to, accept deposits from, and
perform services for the Company, the Guarantors or their respective Affiliates,
and may otherwise deal with the Company, the Guarantors or their respective
Affiliates, as if it were not Trustee.
 
     12. No Recourse against Others. A director, officer, employee or
stockholder, as such, of the Company or any Guarantor shall not have any
liability for any obligations of the Company or such Guarantor under the
Securities or the Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation. Each Holder by accepting a
Security waives and releases all such liability. The waiver and release are part
of the consideration for the issuance of the Securities.
 
     13. Authentication. This Security shall not be valid until authenticated by
the manual signature of the Trustee or an authenticating agent.
 
     14. Abbreviations. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT
(= tenants by the entireties), JT TEN (= joint tenants with right of
survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A
(= Uniform Gifts to Minors Act).
 
     The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture. Request may be made to:

                             SPECIMEN FORM OF NOTE
 
                      UNION TEXAS PETROLEUM HOLDINGS, INC.
 
                          8 1/2% SENIOR NOTE DUE 2007
 
     1. Interest. Union Texas Petroleum Holdings, Inc., a Delaware corporation
(the "Company"), promises to pay interest on the principal amount of this
Security at 8 1/2% per annum from April 15, 1995 until maturity. The Company
will pay interest semiannually on October 15 and April 15 of each year (each an
"Interest Payment Date"), or if any such day is not a Business Day, on the next
succeeding Business Day. Interest on the Securities will accrue from the most
recent Interest Payment Date on which interest has been paid or, if no interest
has been paid, from April 15, 1995; provided, that if there is no existing
Default in the payment of interest, and if this Security is authenticated
between a record date referred to on the face hereof and the next succeeding
Interest Payment Date, interest shall accrue from such next succeeding Interest
Payment Date; provided, further, that the first Interest Payment Date shall be
October 15, 1995. The Company shall pay interest on overdue principal and
premium, if any, from time to time on demand at a rate equal to the interest
rate then in effect; it shall pay interest on overdue installments of interest
(without regard to any applicable grace periods) from time to time on demand at
the same rate to the extent lawful. Interest will be computed on the basis of a
360-day year of twelve 30-day months.
 
     2. Method of Payment. The Company will pay interest on the Securities
(except defaulted interest) to the Persons who are registered Holders of
Securities at the close of business on the record date next preceding the
Interest Payment Date, even if such Securities are canceled after such record
date and on or before such Interest Payment Date. The Holder must surrender this
Security to a Paying Agent to collect principal payments. The Company will pay
the principal of, premium, if any, and interest on the Securities in money of
the United States of America that at the time of payment is legal tender for
payment of public and private debts. The Company, however, may pay such amounts
by check payable in such money. It may mail an interest check to a Holder's
registered address.
 
     3. Ranking and Guarantees. The Securities will be senior unsecured
obligations of the Company. The Company's obligations to pay principal, premium,
if any, and interest with respect to the Securities are unconditionally
guaranteed on a joint and several basis (the "Guarantees") by the guarantors
(the "Guarantors") parties to the Indenture. Each of the Guarantees will be an
unsecured obligation of the Guarantor providing such Guarantee. Certain
limitations to the obligations of the Guarantors are set forth in further detail
in the Indenture. References herein to the Indenture or the Securities shall be
deemed also to refer to the Guarantees set forth in the Indenture except where
the context otherwise requires.
 
     4. Paying Agent and Registrar. Initially, The First National Bank of
Chicago, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Company may change any Paying Agent, Registrar or co-registrar
without notice to any Holder. The Company may act in any such capacity.
 
     5. Indenture. The Company issued the Securities under an Indenture dated as
of March 15, 1995 (the "Indenture") among the Company, the Guarantors and the
Trustee. The terms of the Securities include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of
1939, as amended (15 U.S. Code sec.sec. 77aaa-77bbbb) as in effect on the date
of execution of the Indenture. The Securities are subject to all such terms, and
Holders are referred to the Indenture and such Act for a statement of such
terms. The Securities are unsecured general obligations of the Company limited
to $75,000,000 in aggregate principal amount.
 
     6. Optional Redemption. The Securities may be redeemed at any time, at the
option of the Company, in whole or from time to time in part, at a price equal
to 100% of their principal amount plus accrued and unpaid interest, if any, to
the Redemption Date plus the Make-Whole Premium, if any (the "Redemption
Price").
<PAGE>   3
 
                             SPECIMEN FORM OF NOTE
 
The amount of the Make-Whole Premium with respect to any Security (or portion
thereof) to be redeemed will be equal to the excess, if any, of:
 
          (i) the sum of the present values, calculated as of the Redemption
     Date, of:
 
             (A) each interest payment that, but for such redemption, would have
        been payable on the Security (or portion thereof) being redeemed on each
        Interest Payment Date occurring after the Redemption Date (excluding any
        accrued interest for the period prior to the Redemption Date); and
 
             (B) the principal amount that, but for such redemption, would have
        been payable at the final maturity of the Security (or portion thereof)
        being redeemed;
 
     over
 
          (ii) the principal amount of the Security (or portion thereof) being
     redeemed.
 
The present values of interest and principal payments referred to in clause (i)
above will be determined in accordance with generally accepted principles of
financial analysis. Such present values will be calculated by discounting the
amount of each payment of interest or principal from the date that each such
payment would have been payable, but for the redemption, to the Redemption Date
at a discount rate equal to the Treasury Yield. The Make-Whole Premium will be
calculated by an independent investment banking institution of national standing
appointed by the Company; provided, that if the Company fails to make such
appointment at least 10 business days prior to the Redemption Date, or if the
institution so appointed is unwilling or unable to make such calculation, such
calculation will be made by Goldman, Sachs & Co. or, if such firm is unwilling
or unable to make such calculation, by an independent investment banking
institution of national standing appointed by the Trustee (in any such case, an
"Independent Investment Banker").
 
     For purposes of determining the Make-Whole Premium, "Treasury Yield" means
a rate of interest per annum equal to the weekly average yield to maturity of
United States Treasury Notes that have a constant maturity that corresponds to
the remaining term to maturity of the Securities, calculated to the nearest
1/12 of a year (the "Remaining Term"). The Treasury Yield will be determined as
of the third business day immediately preceding the applicable Redemption Date.
The weekly average yields of United States Treasury Notes will be determined by
reference to the most recent statistical release published by the Federal
Reserve Bank of New York and designated "H.15(519) Selected Interest Rates" or
any successor release (the "H.15 Statistical Release"). If the H.15 Statistical
Release sets forth a weekly average yield for United States Treasury Notes
having a constant maturity that is the same as the Remaining Term, then the
Treasury Yield will be equal to such weekly average yield. In all other cases,
the Treasury Yield will be calculated by interpolation, on a straight-line
basis, between the weekly average yields on the United States Treasury Notes
that have a constant maturity closest to and greater than the Remaining Term and
the United States Treasury Notes that have a constant maturity closest to and
less than the Remaining Term (in each case as set forth in the H.15 Statistical
Release). Any weekly average yields so calculated by interpolation will be
rounded to the nearest 1/100 of 1%, with any figure of 1/200% or above being
rounded upward. If weekly average yields for United States Treasury Notes are
not available in the H.15 Statistical Release or otherwise, then the Treasury
Yield will be calculated by interpolation of comparable rates selected by the
Independent Investment Banker.
 
     Periodic interest installments with respect to which the Interest Payment
Date is on or prior to any Redemption Date will be payable to the Holders of
record at the close of business on the relevant record dates referred to herein,
all as provided in the Indenture.
 
     Notice of redemption will be mailed at least 30 days but not more than 60
days before the Redemption Date to each Holder of Securities to be redeemed at
his registered address. Securities in denominations larger than $1,000 may be
redeemed in part but only in whole multiples of $1,000, provided that if all the
Securities of a Holder are to be redeemed, the entire outstanding amount of
Securities held by such Holder, even if not a
<PAGE>   4
 
                             SPECIMEN FORM OF NOTE
 
whole multiple of $1,000, will be redeemed. On and after the Redemption Date
interest will cease to accrue on Securities or on the portions thereof called
for redemption, as the case may be.
 
     7. Denominations, Transfer, Exchange. The Securities are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of Securities may be registered and Securities may be exchanged as
provided in the Indenture. The Registrar and the Trustee may require a Holder,
among other things, to furnish appropriate endorsements and transfer documents
and to pay any taxes and fees required by law or permitted by the Indenture. The
Registrar need not exchange or register the transfer of any Security or portion
of a Security selected for redemption. Also, it need not exchange or register
the transfer of any Securities for a period of 15 days before a selection of
Securities to be redeemed or during the period between a record date and the
corresponding Interest Payment Date.
 
     8. Persons Deemed Owners. The registered Holder of a Security shall be
treated as its owner for all purposes.
 
     9. Amendments and Waivers. Subject to certain exceptions and limitations,
the Indenture or the Securities may be amended or supplemented with the consent
of the Holders of at least a majority in principal amount of the then
outstanding Securities, and any existing Default under, or compliance with any
provision of, the Indenture may be waived (other than any continuing Default or
Event of Default in the payment of the principal of or premium, if any, or
interest on the Securities) by the Holders of at least a majority in principal
amount of the Securities then outstanding in accordance with the terms of the
Indenture. Without the consent of any Holder, the Company, the Guarantors and
the Trustee may amend or supplement the Indenture or the Securities to evidence
the assumption by any successor to the Company of the covenants in the Indenture
and the Securities; to add to the covenants of the Company for the benefit of
the Holders; to add any additional Events of Default with respect to the
Securities; to provide for uncertificated Securities in addition to or in place
of certificated Securities and to provide for certificated Securities in
addition to or in place of uncertificated Securities; to make any change that
does not adversely affect any Security; to establish the form or terms of
Securities; to permit or facilitate the defeasance or discharge of any series of
Securities; to provide for the acceptance of appointment by a successor Trustee
and the administration of the trusts by more than one Trustee; to provide for
Guarantees of the Securities or to reflect the release of any Guarantor from its
Guarantee, or the addition of any Subsidiary of the Company as a Guarantor; to
cure any ambiguity, omission, defect or inconsistency; or to comply with the
qualification of the Indenture under the Trust Indenture Act of 1939, as
amended.
 
     The right of any Holder to participate in any consent required or sought
pursuant to any provision of the Indenture (and the obligation of the Company to
obtain any such consent otherwise required from such Holder) may be subject to
the requirement that such Holder shall have been the Holder of record of any
Securities with respect to which such consent is required or sought as of a date
identified by the Trustee in a notice furnished to Holders in accordance with
the terms of the Indenture.
 
     Without the consent of each Holder affected, the Company may not (i) reduce
the percentage in principal amount of Securities whose Holders must consent to
an amendment, supplement or waiver, (ii) reduce the rate of or change the time
for payment of interest, including default interest, on any Security, (iii)
reduce the principal of or change the fixed maturity of any Security or alter
the premium or other provisions with respect to redemption, (iv) make any
Security payable in money other than that stated in the Security, (v) impair the
right to institute suit for the enforcement of any payment of principal of, or
premium, if any, or interest on any Security, (vi) reduce the percentage in
principal amount of Securities necessary to waive compliance with certain
provisions of the Indenture or (vii) waive a continuing Default or Event of
Default in the payment of principal of or premium, if any, or interest on the
Securities.
 
     10. Defaults and Remedies. Events of Default include: default in payment of
interest on the Securities for 30 days; default in payment of principal of or
premium, if any, on the Securities; failure by the Company or any Guarantor for
60 days after written notice by the Trustee or by the Holders of at least 25% of
the aggregate principal amount of the Securities then outstanding to it to
comply with any of its other covenants or
<PAGE>   5
 
                             SPECIMEN FORM OF NOTE
 
agreements in the Indenture, the Guarantees or the Securities; the acceleration
of the maturity of any Indebtedness of the Company or any Restricted Subsidiary
(other than the Securities or any Non-Recourse Indebtedness) that has an
outstanding principal amount of $20 million or more individually or in the
aggregate; a default in the payment of principal or interest in respect of any
Indebtedness of the Company or any Restricted Subsidiary (other than the
Securities or any Non-Recourse Indebtedness) having an outstanding principal
amount of $20 million or more individually or in the aggregate, and such default
shall be continuing for a period of 30 days without the Company or such
Restricted Subsidiary, as the case may be, effecting a cure of such default; or
certain events involving bankruptcy, insolvency or reorganization of the Company
or any Restricted Subsidiary. If an Event of Default occurs and is continuing,
the Trustee or the Holders of at least 25% in principal amount of the then
outstanding Securities may declare the principal of, and premium, if any, and
interest on all the Securities to be immediately due and payable, except that in
the case of an Event of Default arising from certain events of bankruptcy,
insolvency or reorganization of the Company or any Restricted Subsidiary, all
outstanding Securities become due and payable immediately without further action
or notice. The amount due and payable upon the acceleration of any Security is
equal to 100% of the principal amount thereof plus accrued interest to the date
of payment. Holders may not enforce the Indenture or the Securities except as
provided in the Indenture. The Trustee may require indemnity reasonably
satisfactory to it before it enforces the Indenture or the Securities. Subject
to certain limitations, Holders of a majority in principal amount of the then
outstanding Securities may direct the Trustee in its exercise of any trust or
power. The Trustee may withhold from Holders notice of any continuing default
(except a default in payment of principal or interest) if it determines that
withholding notice is in their interests. The Company must furnish an annual
compliance certificate to the Trustee.
 
     11. Trustee Dealings with Company and Guarantors. The Trustee, in its
individual or any other capacity, may make loans to, accept deposits from, and
perform services for the Company, the Guarantors or their respective Affiliates,
and may otherwise deal with the Company, the Guarantors or their respective
Affiliates, as if it were not Trustee.
 
     12. No Recourse against Others. A director, officer, employee or
stockholder, as such, of the Company or any Guarantor shall not have any
liability for any obligations of the Company or such Guarantor under the
Securities or the Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation. Each Holder by accepting a
Security waives and releases all such liability. The waiver and release are part
of the consideration for the issuance of the Securities.
 
     13. Authentication. This Security shall not be valid until authenticated by
the manual signature of the Trustee or an authenticating agent.
 
     14. Abbreviations. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT
(= tenants by the entireties), JT TEN (= joint tenants with right of
survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A
(= Uniform Gifts to Minors Act).
 
     The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture. Request may be made to:
