                             APACHE FINANCE PTY LTD


                                Debt Securities


                        Guaranteed by Apache Corporation



                       UNDERWRITING AGREEMENT BASIC TERMS


         Apache Finance Pty Ltd (A.C.N. 080 571 900), a proprietary company with
limited liability duly organized under the laws of the Australian Capital
Territory (the "Company"), may issue and sell from time to time its debt
securities (the "Debt Securities").  The Debt Securities are unconditionally
guaranteed as to payment of principal, premium, if any, Additional Amounts (as
defined in the Indenture), if any, and interest by Apache Corporation (the
"Guarantor").  The Debt Securities are issuable under, and the guarantee thereof
by the Guarantor (the "Guarantee") is contained in, an indenture, dated as of
December 9, 1997 (the "Indenture"), between the Company, the Guarantor and The
Chase Manhattan Bank, as trustee (the "Trustee").  Each issue of Debt Securities
may vary as to series, aggregate principal amount, maturity, interest rate or
rates and timing of payments thereof, redemption provisions, if any, and any
other variable terms as set forth in the Terms Agreement (as defined below)
relating thereto which the Indenture contemplates may be set forth in the Debt
Securities as issued from time to time.

         Whenever the Company determines to make an offering of Debt
Securities, the Company and the Guarantor will enter into an agreement (the
"Terms Agreement") providing for the sale of such securities (the "Offered
Securities") to, and the purchase and offering thereof by, one or more
underwriters specified in the Terms Agreement (the "Underwriters", which term
shall include any Underwriters substituted pursuant to Section 10 hereof).  The
Terms Agreement relating to the Offered Securities shall specify the names of
the Underwriters participating in such offering, the amount of Offered
Securities which each such Underwriter severally agrees to purchase, the price
at which the Offered Securities are to be purchased by the Underwriters from
the Company, the initial public offering price, the time and place of delivery
and payment, such other information as is indicated in





<PAGE>   7
Exhibit A hereto and such other terms as are agreed by the Company and the
Underwriters.  In addition, each Terms Agreement shall specify whether the
Company has agreed to grant to the Underwriters an option to purchase
additional Offered Securities to cover over-allotments, if any, and the amount
of Offered Securities subject to such option (the "Option Securities").  As
used herein, the term "Offered Securities" shall include the Option Securities,
if any, and "Representatives" shall mean the Underwriter or Underwriters so
specified in the Terms Agreement or, if no Underwriter is so specified, shall
mean each Underwriter.  The Terms Agreement may be in the form of an exchange
of any standard form of written telecommunication between the Underwriters and
the Company.  The offering of the Offered Securities will be governed by the
Terms Agreement, as supplemented hereby (collectively, this "Agreement"), and
this Agreement shall inure to the benefit of and be binding upon each
Underwriter participating in the offering of the Offered Securities.

         The Company and the Guarantor have prepared and filed with the
Securities and Exchange Commission (the "Commission") a registration statement
on Form S-3 (Nos. 333-39973 and 333-39973-01) for the registration of Debt
Securities, including the Offered Securities and the Guarantee, under the
Securities Act of 1933, as amended (the "1933 Act"), and the offering thereof
from time to time in accordance with Rule 415 of the rules and regulations of
the Commission under the 1933 Act (the "1933 Act Regulations"), and have
prepared and filed such amendments thereto as may have been required to the
date hereof.  Such registration statement, as amended, has been declared
effective by the Commission, and the Indenture has been qualified under the
Trust Indenture Act of 1939 (the "1939 Act").  As provided in Section 3(a), a
prospectus supplement reflecting the terms of the Offered Securities, the terms
of the offering thereof and the other matters set forth therein has been
prepared and will be filed pursuant to Rule 424 under the 1933 Act.  Such
prospectus supplement, in the form first filed after the date of the Terms
Agreement pursuant to Rule 424, is herein referred to as the "Prospectus
Supplement".  Such registration statement, as amended at the date of the Terms
Agreement, including the exhibits thereto and the documents incorporated by
reference therein, is herein called the "Registration Statement".  Any
registration statement filed pursuant to Rule 462(b) of the 1933 Act
Regulations is herein referred to as the "Rule 462(b) Registration Statement,"
and after such filing the term "Registration Statement" shall include the Rule
462(b) Registration Statement.  The basic prospectus included in the
Registration Statement relating to all offerings of Debt Securities and the
Guarantee under the Registration Statement, as supplemented by the Prospectus
Supplement, is herein called the "Prospectus", except that, if such basic





                                       2
<PAGE>   8
prospectus is amended or supplemented on or prior to the date on which the
Prospectus Supplement is first filed pursuant to Rule 424, the term
"Prospectus" shall refer to the basic prospectus as so amended or supplemented
and as supplemented by the Prospectus Supplement or, if any revised prospectus
shall be provided to the Underwriters by the Company and the Guarantor for
their use in connection with the offering of the Offered Securities which
differs from such basic prospectus and Prospectus Supplement (whether or not
required to be filed by the Company pursuant to Rule 424), the term
"Prospectus" shall refer to such revised prospectus (including any prospectus
supplement) from and after the time it is first provided to the Underwriters
for such use, in either case including the documents filed by the Company with
the Commission pursuant to the Securities Exchange Act of 1934, as amended (the

         to transact business and is in good standing in each jurisdiction in
         which the character or location of its properties or the nature or the

         of the ownership or leasing of property or the conduct of business,
         except where the failure to so qualify or to be in good standing would
         not have a material adverse effect on the condition, financial or
         otherwise, on the results of operations, business affairs or business
         prospects of the Company or on its ability to perform its obligations
         hereunder or under the Offered Securities or the Indenture.  The

         in the State of Texas and in each other jurisdiction in which such
         qualification is required, whether by reason of the ownership or
         leasing of property or the conduct of business, except where the
         failure to so qualify and be in good standing would not have a
         material adverse effect on the condition, financial or otherwise, or
         the results of operations, business affairs or business prospects of
         the Guarantor and its subsidiaries considered as one enterprise.

         or business prospects of the Guarantor and its subsidiaries considered
         as one enterprise; and, except as described in the Prospectus, all of

         pledge, lien, encumbrance, claim or equity.

         Representation Date, does not and will not include an untrue statement
         of a material fact or omit to state a material fact necessary in order
         to make the statements therein, in the light of the circumstances
         under which they were made, not misleading; provided, however, that
         the representations and warranties in this subsection shall not apply
         to statements in or omissions from the Registration Statement and the
         Rule 462(b) Registration Statement, if any, or the Prospectus made in
         reliance upon and in conformity with information furnished to the
         Company or the Guarantor in writing by the Underwriters expressly for

         in all material respects with the requirements of the 1934 Act and the
         rules and regulations of the Commission promulgated thereunder (the
         "1934 Act Regulations"), and, when read together and with the other

         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary in order to make the statements
         therein, in the light of the circumstances under which they were or
         are made, not misleading.

                 (f)  The accountants who certified the financial statements
         included or incorporated by reference in the Registration Statement
         and the Prospectus are independent public accountants with respect to
         the Company and the Guarantor as required by the 1933 Act and the 1933
         Act Regulations.

                 (g)  The financial statements and any supporting schedules of
         the Guarantor and its subsidiaries included or incorporated by
         reference in the Registration Statement and the Prospectus present
         fairly the consolidated financial position of the Guarantor and its

         Commission's rules and guidelines with respect to pro forma financial
         statements and have been properly compiled on the bases described
         therein, and the assumptions used in the preparation thereof are
         reasonable and the adjustments used therein are appropriate to give
         effect to the transactions and circumstances referred to therein.

                 (h)  The petroleum engineers who have consented to being named
         as having reviewed certain reserve data included or incorporated by

                 (i)  This Agreement and the applicable Delayed Delivery
         Contracts (as defined below), if any, have been duly authorized,
         executed and delivered by the Company and the Guarantor and, upon

         laws relating to or affecting enforcement of creditors' rights
         generally or by general equity principles, and except further as
         enforcement thereof may be limited by (1) requirements that a claim
         with respect to any Debt Securities denominated other than in U.S.
         dollars (or a foreign currency or composite currency judgment in
         respect of such claim) be converted into U.S. dollars at a rate of
         exchange prevailing on a date determined pursuant to applicable law or
         (2) governmental authority to limit, delay or prohibit the making of
         payments outside the United States. The Offered Securities have been

         constitute valid and legally binding obligations of the Company
         enforceable in accordance with their terms, except as enforcement
         thereof may be limited by bankruptcy, insolvency, reorganization,

         composite currency judgment in respect of such claim) be converted
         into U.S. dollars at a rate or exchange prevailing on a date
         determined pursuant to applicable law or (2) governmental authority to
         limit, delay or prohibit the making of payments outside the United
         States.  The Offered Securities and the Indenture, including the
         Guarantee, will be substantially in the form heretofore delivered to
         the Underwriters and conform in all material respects to all
         statements relating thereto contained in the Prospectus; and each
         Holder (as defined in the Indenture) of Offered Securities will be
         entitled to the benefits of the Indenture.

                 (j)  The Guarantee has been duly and validly authorized by the
         Guarantor, and, when the Offered Securities are issued, authenticated
         and delivered pursuant to the provisions of this Agreement and the
         Indenture against payment of the consideration therefor, the Guarantee
         will be a valid and legally binding obligation of the Guarantor with
         respect to the Offered Securities enforceable in accordance with its
         terms, except as enforcement thereof may be limited by bankruptcy,
         insolvency, moratorium or other laws relating to or affecting
         enforcement of creditors' rights generally against the Guarantor or by
         general equity principles and except further as enforcement thereof
         may be limited by (1) requirements that a claim with respect to any
         Offered Securities denominated other than in U.S. dollars (or a
         foreign currency or composite currency judgment in respect of such
         claim) be converted into U.S. dollars at a rate of exchange prevailing
         on a date determined pursuant to applicable law or (2) governmental
         authority to limit, delay or prohibit the making of payments outside
         the United States, and the Holder of the Offered Securities will be
         entitled to the benefits of the Guarantee.

         agreement, note, lease or other instrument to which it is a party or
         by which it or any of them or their properties may be bound, where the
         consequences of such violation or default would have a material
         adverse effect on the condition, financial or otherwise, or the
         results of operations, business affairs or business prospects of the
         Company or the Guarantor and its subsidiaries considered as one
         enterprise; and the execution and delivery of this Agreement, each
         Delayed Delivery Contract, if any, and the Indenture and the
         consummation of the transactions contemplated herein and therein have
         been duly authorized by all necessary corporate action of the Company
         and the Guarantor and will not conflict with or constitute a breach
         of, or default under, or result in the creation or imposition of any
         lien, charge or encumbrance upon any property or assets of the

         charter or by-laws of the Company or the Guarantor or any law,
         administrative regulation or administrative or court order or decree,
         where the consequences of such conflict, breach, creation, imposition,

         condition, financial or otherwise, or the results of operations,
         business affairs or business prospects of the Company or the Guarantor
         and its subsidiaries considered as one enterprise.

                 (m)  No consent, approval, authorization, order or decree of
         any court or governmental agency or body is required for the
         consummation by the Company and the Guarantor of the transactions
         contemplated by this Agreement or in connection with the sale of
         Offered Securities hereunder, except such as have been obtained or

         such violations as would not, singly or in the aggregate, have a
         material adverse effect on the condition, financial or otherwise, or
         the results of operations, business affairs or business prospects of
         the Company or the Guarantor and its subsidiaries considered as one
         enterprise, and (2) to the best of the Company's and the Guarantor's
         knowledge, there are no events or circumstances that could reasonably
         be expected to be the basis of an order for clean-up or remediation,
         or an action, suit or proceeding by any private party or governmental
         body or agency, against or affecting the Guarantor or any of its
         subsidiaries relating to any Hazardous Materials or the violation of
         any Environmental Laws, which, singly or in the aggregate, could
         reasonably be expected to have a material adverse effect on the
         condition,

         financial or otherwise, or the results of operations, business affairs
         or business prospects of the Company or the Guarantor and its
         subsidiaries considered as one enterprise.

                 (w)  Except as described in the Prospectus, or as has already
         been paid or authorized for payment, no stamp duty or similar tax or
         duty is payable under applicable laws or regulations of the
         Commonwealth of Australia, any of its States, territories or
         possessions, or any political subdivision thereof (collectively,
         "Australia") in connection with the creation, issuance or delivery of
         the Offered Securities, the transfer of any of the Offered Securities
         or with respect to the execution and delivery of this Agreement, the
         Offered Securities or the Indenture or any document contemplated
         hereby or thereby.

                 (x)  Except as described in the Prospectus, payments made by
         the Company under the Offered Securities or the Guarantor under the
         Guarantee or either of them hereunder or under the Indenture will not
         be subject under the current laws or regulations of Australia to any
         withholdings or similar charges for or on account of taxation.

                 (y)  The choice of the laws of the State of New York as the
         governing law of the Offered Securities, the Indenture and this
         Agreement is a valid choice of law under the laws of Australia and
         courts of Australia will honor this choice of law.  The Company has
         the power to submit and pursuant to this Agreement and the Indenture
         has legally, validly, effectively and irrevocably submitted to the
         personal jurisdiction of the United States District Court for the
         Southern District of New York and the Supreme Court of New York, New
         York County (including, in each case, any appellate courts therefrom)
         in any suit, action or proceeding against it arising out of or related
         to any of the Offered Securities, the Indenture and the Guarantee or
         with respect to its obligations, liabilities or any other matter
         arising out of or in connection with the sale of the Offered
         Securities by the Company to the Underwriters under this Agreement and
         has validly and irrevocably waived any objection to the venue of a
         proceeding in any such court; and has the power to designate, appoint
         and empower and pursuant to this Agreement and the Indenture has
         legally, validly, effectively and irrevocably designated, appointed
         and empowered an agent for service of process in any suit or
         proceeding based on or arising under this Agreement, the Offered
         Securities or the Indenture, as the case may be, in any federal or
         state court in the State of New York.

                 (z)  Except as described in the Prospectus, any final judgment
         for a definite sum of money rendered by any court





                                       12
<PAGE>   18
         of the State of New York or of the United States located in the State
         of New York having jurisdiction under its own domestic laws in respect
         of any suit, action or proceeding against the Company based upon any
         instruments or agreements entered into for the consummation of the
         transactions contemplated herein would be declared enforceable against
         the Company by the courts of Australia without reexamination, review
         of the merits of the cause of action in respect of which the original
         judgment was given or relitigation of the matters adjudicated upon or
         payment of any stamp, registration or similar tax or duty, provided
         that (A) the judgment is consistent with public policy in Australia
         and any relevant political subdivision, (B) the judgment was not given
         or obtained by fraud or in a manner contrary to natural justice, (C)
         the judgment was not based on a clear mistake of law or fact, (D) the
         judgment was not directly or indirectly for the payment of taxes or
         other charges of a like nature or of a fine or other penalty, (E) the
         judgment is for a definite sum, and (F) there has been no prior
         judgment in another court between the same parties concerning the same
         issues as are dealt with in the judgment to be enforced in Australia.
         The Company is not aware of any reason why the enforcement in
         Australia of such a judgment in respect of any of the instruments or
         agreements executed for consummation of the transactions contemplated
         herein or in the Prospectus would be contrary to public policy in
         Australia or any political subdivision of either of them.

                 (aa)  The Company, and its obligations under this Agreement,
         the Offered Securities and the Indenture, are subject to civil and
         commercial law and to suit and neither it nor any of its properties,
         assets or revenues have any right of immunity, on the grounds of
         sovereignty, from any legal action, suit or proceeding, from the
         giving of any relief in any such legal action, suit or proceeding,
         from setoff or counterclaim, from the jurisdiction of any Australian,
         New York State or U.S. federal court, as the case may be, from service
         of process, attachment upon or prior to judgment, or attachment in aid
         of execution of judgment, or from execution or enforcement of a
         judgment, or other legal process or proceeding for the giving of any
         relief or for the enforcement of a judgment, in any such court, with
         respect to its obligations or liabilities or any other matter under or
         arising out of or in connection with the Offered Securities, this
         Agreement or the Indenture; and, to the extent that the Company or any
         of its properties, assets or revenues may have or may hereafter become
         entitled to any such right of immunity in any such court in which
         proceedings may at any time be commenced, the





                                       13
<PAGE>   19
         Company has waived or will waive such right to the extent permitted by
         law and has consented to such relief and enforcement as provided in
         this Agreement and the Indenture.

                 (bb)  It is not necessary under the laws of Australia or any
         authority or agency therein in order to enable an owner of any
         interest in the Offered Securities or the Guarantee to enforce its
         rights under the Offered Securities or the Guarantee or to enable any
         of the Underwriters to enforce its rights under this Agreement, as the
         case may be, that it should, as a result solely of its holding or
         underwriting, as the case may be, of the Offered Securities, be
         licensed, qualified or otherwise entitled to carry on business in
         Australia or any authority or agency therein; the Offered Securities,
         the Indenture and this Agreement are in proper legal form under the
         laws of Australia and any political subdivision thereof or authority
         or agency therein for the enforcement thereof against the Company
         therein; and it is not necessary to ensure the legality, validity,
         enforceability or admissibility in evidence of the Offered Securities,
         the Indenture or this Agreement in Australia or any authority or
         agency therein that any of them be filed or recorded or enrolled with
         any court, authority or agency in, or that any stamp, registration or
         similar taxes or duties be paid to any court, authority or agency of
         Australia.

                 (cc)  Except as described in the Prospectus, no exchange
         control authorization or other authorization, approval, consent or
         license of any governmental authority or agency of or in Australia is
         required for the payment by the Company of any amounts in United
         States dollars pursuant to the terms of the Offered Securities or to
         the Underwriters pursuant to this Agreement.

         Any certificate signed by any director or officer of the Company or
the Guarantor and delivered to the Representatives or to counsel for the
Underwriters shall be deemed a representation and warranty by the Company or
the Guarantor, as the case may be, as to the matters covered thereby.

         SECTION 2.  Purchase and Sale.

         (a)     The several commitments of the Underwriters to purchase the
Offered Securities pursuant to this Agreement shall be deemed to have been made
on the basis of the representations and warranties herein contained and shall
be subject to the terms and conditions herein and therein set forth.  Offered
Securities which are subject to Delayed Delivery Contracts are herein sometimes
referred to as "Delayed Delivery Offered Securities" and Offered Securities
which are not subject to Delayed Delivery





                                       14
<PAGE>   20
Contracts are herein sometimes referred to as "Immediate Delivery Offered
Securities".

         (b)     In addition, on the basis of the representations and
warranties herein contained and subject to the terms and conditions herein set
forth, the Company may grant, if so provided in the Terms Agreement, an option
to the Underwriters named in the Terms Agreement, severally and not jointly, to
purchase up to the principal amount of Option Securities set forth therein at
the same price per security (plus, except as otherwise provided in the Terms
Agreement, interest, if any, accrued and unpaid from the Closing Time until the
applicable Date of Delivery), as is applicable to the Offered Securities.  Such
option, if granted, will expire 30 days after the date of the Terms Agreement,
and may be exercised in whole or in part from time to time only for the purpose
of covering over-allotments which may be made in connection with the offering
and distribution of the Offered Securities upon notice by the Representatives
to the Company setting forth the principal amount of Option Securities as to
which the several Underwriters are then exercising the option and the time and
date of payment and delivery for such Option Securities.  Any such time and
date of delivery (a "Date of Delivery") shall be determined by the
Representatives, but shall not be later than seven full business days and not
earlier than two full business days after the exercise of said option, nor in
any event prior to the Closing Time, as hereinafter defined, unless otherwise
agreed upon by the Representatives, the Company and the Guarantor.  If the
option is exercised as to all or any portion of the Option Securities, each of
the Underwriters, acting severally and not jointly, will purchase the
proportion of the total principal amount of Option Securities then being
purchased that the principal amount of Immediate Delivery Offered Securities
each such Underwriter has agreed to purchase, as set forth in the Terms
Agreement, bears to the total principal amount of Immediate Delivery Offered
Securities, subject to such adjustments as the Representatives in their
discretion shall make to eliminate any sales or purchases in less than
authorized denominations.

         (c)     Payment of the purchase price for, and delivery of, the
Immediate Delivery Offered Securities to be purchased by the Underwriters shall
be made at the place set forth in the Terms Agreement, or at such other place
as shall be agreed upon by the Representatives, the Company and the Guarantor,
on the third business day (unless postponed in accordance with the provisions
of Section 10) following the date of the Terms Agreement or such other time as
shall be agreed upon by the Underwriters, the Company and the Guarantor (such
time and date being referred to as the "Closing Time").  Except as specified in
the Terms Agreement, payment shall be made to the Company by wire transfer





                                       15
<PAGE>   21
in same day funds to the account specified in the Terms Agreement against
delivery to the Underwriters for the respective accounts of the Underwriters of
the Immediate Delivery Offered Securities to be purchased by them (unless the
Offered Securities are issuable only in the form of one or more global
instruments registered in the name of a depository or a nominee of a
depository, in which event the Underwriters' interest in such global instrument
shall be noted in a manner satisfactory to the Underwriters and their counsel).
In addition, in the event that any or all of the Option Securities are
purchased by the Underwriters, payment of the purchase price for, and delivery
of certificates representing, such Option Securities shall be made at such
place as shall be agreed upon by the Representatives and the Company, on each
Date of Delivery as agreed by the Representatives and the Company.  The
Immediate Delivery Offered Securities shall be in such denominations and
registered in such names as the Underwriters may request in writing at least
two business days prior to the Closing Time or relevant Date of Delivery, as
the case may be.  The Immediate Delivery Offered Securities, which if agreed by
the Representatives may be in temporary form, will be made available for
examination and packaging by the Representatives on or before the first
business day prior to the Closing Time or relevant Date of Delivery, as the
case may be.

         (d)     If authorized by the Terms Agreement, the Underwriters named
therein may solicit offers to purchase Offered Securities from the Company
pursuant to delayed delivery contracts ("Delayed Delivery Contracts")
substantially in the form of Exhibit B hereto, with such changes therein as the
Company and the Guarantor may approve.  As compensation for arranging Delayed
Delivery Contracts, the Company or the Guarantor, as the case may be, will pay
to the Representatives at the Closing Time, for the account of the
Underwriters, a fee equal to that percentage of the aggregate principal amount
of Delayed Delivery Offered Securities for which Delayed Delivery Contracts are
made at the Closing Time as is specified in the Terms Agreement.  Any Delayed
Delivery Contracts are to be with institutional investors of the types set
forth in the Prospectus Supplement.  At the Closing Time the Company and the
Guarantor will enter into Delayed Delivery Contracts (for not less than the
minimum principal amount of Delayed Delivery Offered Securities per Delayed
Delivery Contract specified in the Terms Agreement) with all purchasers
proposed by the Underwriters and previously approved by the Company and the
Guarantor as provided below, but not for an aggregate principal amount of
Offered Securities in excess of that specified in the Terms Agreement.  The
Underwriters will not have any responsibility for the validity or performance
of Delayed Delivery Contracts.





                                       16
<PAGE>   22
         (e)     The Representatives are to submit to the Company, at least two
business days prior to the Closing Time, the names of any institutional
investors with which it is proposed that the Company will enter into Delayed
Delivery Contracts and the principal amount of Delayed Delivery Offered
Securities to be purchased by each of them, and the names of the institutions
with which the making of Delayed Delivery Contracts is approved by the Company
and the principal amount of Delayed Delivery Offered Securities to be covered
by each such Delayed Delivery Contract.

         (f)     The principal amount of Offered Securities agreed to be
purchased by the respective Underwriters pursuant to this Agreement shall be
reduced by the principal amount of Delayed Delivery Offered Securities covered
by Delayed Delivery Contracts, as to each Underwriter as set forth in a written
notice delivered by the Underwriters to the Company; provided, however, that
the total principal amount of Immediate Delivery Offered Securities to be
purchased by all Underwriters shall be the total amount of the Offered
Securities covered by this Agreement, less the total principal amount of
Delayed Delivery Offered Securities covered by Delayed Delivery Contracts.

         SECTION 3.  Covenants of the Company and the Guarantor.  The Company
and the Guarantor covenant with each Underwriter as follows:

                 (a)      Immediately following the execution of the Terms
         Agreement, the Company will prepare a Prospectus Supplement in form
         approved by the Representatives setting forth the principal amount of
         Offered Securities and their terms not otherwise specified in the
         Indenture, if applicable, the names of the Underwriters and the
         principal amount of the Offered Securities which each severally has
         agreed to purchase, the names of the Underwriters, the price at which
         the Offered Securities are to be purchased by the Underwriters from
         the Company, the initial public offering price, the selling concession
         and reallowance, if any, any delayed delivery arrangements, and such
         other information as the Representatives and the Company deem
         appropriate in connection with the offering of the Offered Securities.
         The Company will promptly transmit copies of the Prospectus Supplement
         to the Commission for filing pursuant to Rule 424 of the 1933 Act
         Regulations and will furnish to the Underwriters named therein as many
         copies of the Prospectus (including the Prospectus Supplement) as the
         Representatives shall reasonably request.

                 (b)      If at any time when the Prospectus is required by the
         1933 Act to be delivered in connection with sales of the Offered
         Securities any event shall occur or condition exist





                                       17
<PAGE>   23
         as a result of which it is necessary, in the opinion of counsel for
         the Underwriters or counsel for the Guarantor and the Company, to
         amend or supplement the Prospectus in order that the Prospectus will
         not include an untrue statement of a material fact or omit to state
         any material fact necessary in order to make the statements therein
         not misleading in the light of the circumstances existing at the time
         the Prospectus is delivered to a purchaser, or if it shall be
         necessary, in the opinion of either such counsel, to amend or
         supplement the Registration Statement or the Prospectus in order to
         comply with the requirements of the 1933 Act or the 1933 Act
         Regulations, the Company and the Guarantor will promptly amend the
         Registration Statement and the Prospectus, whether by filing documents
         pursuant to the 1934 Act or the 1933 Act or otherwise, as may be
         necessary to correct such untrue statement or omission or to make the
         Registration Statement and the Prospectus comply with such
         requirements.

                 (c)  The Guarantor will make generally available to its
         security holders as soon as practicable, but not later than 90 days
         after the close of the period covered thereby, an earnings statement
         (in form complying with the provisions of Rule 158 of the 1933 Act
         Regulations) covering each twelve month period beginning, in each
         case, not later than the first day of the Guarantor's fiscal quarter
         next following the "effective date" (as defined in such Rule 158) of
         the Registration Statement with respect to each sale of Offered
         Securities.

                 (d)  While the Prospectus is required by the 1933 Act to be
         delivered in connection with sales of the Offered Securities, the
         Company or the Guarantor will give the Representatives notice of its
         intention to file any additional registration statement with respect
         to the registration of additional Debt Securities, any amendment to
         the Registration Statement (including any filing under Rule 462(b)) or
         any amendment or supplement to the Prospectus, whether pursuant to the
         1934 Act, the 1933 Act or otherwise; will furnish the Underwriters
         with copies of any such amendment or supplement or other documents
         proposed to be filed a reasonable time in advance of such proposed
         filing or use, as the case may be; and will not file any such
         amendment or supplement or other documents in a form to which the
         Representatives or counsel to the Underwriters reasonably object.

                 (e)  While the Prospectus is required by the 1933 Act to be
         delivered in connection with sales of the Offered Securities, the
         Company or the Guarantor will notify the





                                       18
<PAGE>   24
         Representatives immediately, and promptly confirm the notice in
         writing, of (i) the effectiveness of any amendment to the Registration
         Statement, (ii) the transmittal to the Commission for filing of any
         supplement to the Prospectus or any document to be filed pursuant to
         the 1934 Act which will be incorporated by reference into the
         Registration Statement or the Prospectus, (iii) the receipt of any
         comments from the Commission with respect to the Registration
         Statement, the Prospectus or the Prospectus Supplement, (iv) any
         request by the Commission for any amendment to the Registration
         Statement, or any amendment or supplement to the Prospectus or for
         additional information, (v) the issuance by the Commission of any stop
         order suspending the effectiveness of the Registration Statement or
         the initiation of any proceedings for that purpose and (vi) any change
         in the rating assigned by any nationally recognized statistical rating
         organization to any debt securities of the Company or the Guarantor or
         the public announcement by any nationally recognized statistical
         rating organization that it has under surveillance or review, with
         possible negative implications, its rating of any debt securities of
         the Company or the Guarantor.  The Company and the Guarantor will make
         every reasonable effort to prevent the issuance of any stop order and,
         if any stop order is issued, to obtain the lifting thereof at the
         earliest possible moment.

                 (f)  The Company will deliver to each Underwriter one
         conformed copy of the Registration Statement (as originally filed) and
         of each amendment thereto (including exhibits filed therewith or
         incorporated by reference therein and documents incorporated by
         reference in the Prospectus) and will also deliver to the
         Representatives as many conformed copies of the Registration Statement
         as originally filed and of each amendment thereto (without exhibits)
         as the Representatives may reasonably request.  While the Prospectus
         is required by the 1933 Act to be delivered in connection with sales
         of the Offered Securities, the Company will furnish to the
         Representatives as many copies of the Prospectus (including the
         Prospectus Supplement) as the Representatives reasonably request.

                 (g)  The Company and the Guarantor will endeavor, in
         cooperation with the Underwriters, to qualify the Offered Securities
         for offering and sale under the applicable securities laws of such
         states and other jurisdictions of the United States as the
         Underwriters may designate, and will maintain such qualifications in
         effect for as long as may be required for the distribution of the
         Offered Securities; provided, however, that neither the Company nor
         the Guarantor shall be obligated to file any general consent





                                       19
<PAGE>   25
         to service of process or to qualify as a foreign corporation in any
         jurisdiction in which it is not so qualified.  The Company and the
         Guarantor will file such statements and reports as may be required by
         the laws of each jurisdiction in which the Offered Securities have
         been qualified as above provided.  The Company or the Guarantor will
         promptly advise the Representatives of the receipt by the Company of
         any notification with respect to the suspension of the qualification
         of the Offered Securities for sale in any such state or jurisdiction
         or the initiating or threatening of any proceeding for such purpose.

                 (h)  The Company and the Guarantor, during the period when the
         Prospectus is required to be delivered under the 1933 Act or the 1934
         Act in connection with sales of the Offered Securities, will file all
         documents required to be filed with the Commission pursuant to
         Sections 13, 14 or 15(d) of the 1934 Act within the time periods
         prescribed by the 1934 Act and the 1934 Act Regulations.

                 (i)  If specified in the Terms Agreement, between the date of
         the Terms Agreement and the completion of the distribution of the
         Offered Securities or the Closing Time, whichever is later, or such
         other time as is specified in the Terms Agreement, the Company or the
         Guarantor will not, without the prior written consent of the
         Representatives, offer or sell, grant any option for the sale of, or
         enter into any agreement to sell, any debt securities of the Company
         or the Guarantor substantially similar to the Offered Securities
         (other than the Offered Securities that are to be sold pursuant to
         such agreement or commercial paper in the ordinary course of

                 with their terms, except as enforcement thereof may be limited
                 by bankruptcy, insolvency, reorganization, moratorium or other

                 summarize certain provisions of documents specifically
                 referred to therein, are accurate summaries of such

                                       22

                 Statement or any Rule 462(b) Registration Statement has been
                 issued under the 1933 Act or proceedings therefor initiated or
                 threatened by the Commission.

                          (ix)  The Registration Statement, including any Rule
                 462(b) Registration Statement, and the Prospectus (except for
                 financial statements and engineering reports and other
                 financial or engineering data, and except for those parts of
                 the Registration Statement that constitute the Form T-1, as to
                 which such counsel need not express any opinion), as of their
                 respective effective or issue dates, appeared on their face to
                 be appropriately responsive to the requirements of the 1933
                 Act and the 1933 Act Regulations.

                 Federal Income Tax Considerations", to the extent that such
                 information constitutes matters of law, summaries of legal
                 matters or legal conclusions, has been reviewed by such
                 counsel and is correct.

                          (xi)  The Company has legally, validly, effectively
                 and irrevocably submitted to the personal jurisdiction of any
                 federal or state court in the State of New York, County of New
                 York in any suit or proceeding based on or arising under this

                 to the venue of a proceeding in any such court as provided in
                 Section 14 of this Agreement; and the Company has the power to

         of officers of the Company and the Guarantor contained in any

                 the results of operations, business affairs or business
                 prospects of the Guarantor and its subsidiaries considered as

                 operations, business affairs or business prospects of the
                 Guarantor and its subsidiaries considered as one enterprise;

                          In rendering such opinion, Zurab S. Kobiashvili may
         rely (i) as to matters of fact upon the representations of officers of
         the Guarantor contained in any certificate delivered to such counsel
         and certificates of public officials, which certificates shall be
         attached to or delivered with such opinion; and (ii) as to matters of
         the laws of Australia covered thereby, upon the opinion of Arthur
         Robinson & Hedderwicks furnished pursuant to this Agreement.  Such
         opinion shall be limited to the General Corporation Law of the State
         of Delaware, the laws of the State of Texas and the laws of the United
         States of America.

                          (3)     The favorable opinion, dated as of the
         Closing Time, of Arthur Robinson & Hedderwicks, Australian counsel to
         the Company, in form and substance satisfactory to the
         Representatives, to the effect that:

                               (i)  The Company has been duly incorporated and
                 is validly existing as a corporation under the laws of the
                 Australian Capital Territory, Australia, and has no
                 subsidiaries.

                              (ii)  The Company has corporate power and
                 authority to own, lease and operate its properties and conduct
                 its business as described in the Registration Statement.

                             (iii)  To such counsel's knowledge, after having
                 made inquiries of the Secretary of the Company, the Company is
                 duly qualified as a foreign corporation to transact business
                 and is in good standing in each jurisdiction in which such
                 qualification is required to transact business whether by
                 reason of ownership or leasing of property or the conduct of
                 business, except where the failure so to qualify could not
                 reasonably be expected to have a material adverse effect on
                 the business, operations or condition, financial or otherwise,
                 or the results of operations of the Company

                 or its ability to perform its obligations hereunder or under
                 the Offered Securities or the Indenture.

                          (iv)  This Agreement and the applicable Delayed
                 Delivery Contracts, if any, have been duly authorized,
                 executed and delivered by the Company.

                          (v)  The Indenture has been duly authorized, executed
                 and delivered by the Company and (assuming the Indenture has
                 been duly authorized, executed and delivered by the Trustee)
                 constitutes a legal, valid and binding agreement of the
                 Company, enforceable in accordance with its terms, except as
                 enforcement thereof may be limited by bankruptcy, insolvency,
                 moratorium or other laws relating to or affecting enforcement
                 of creditors' rights against the Company or by general equity
                 principles.

                          (vi)  The Offered Securities have been duly
                 authorized and, when the Offered Securities are executed and
                 authenticated as specified in the Indenture and delivered
                 against payment pursuant to the Terms Agreement, as
                 supplemented by this Agreement, or any Delayed Delivery
                 Contracts, will constitute valid and binding obligations of
                 the Company, enforceable in accordance with its terms, except
                 as enforcement thereof may be limited by bankruptcy,
                 insolvency, moratorium or other laws relating to or affecting
                 enforcement of creditors' rights against the Company or by
                 general equity principles.

                          (vii)  No consent, approval, authorization, order or
                 decree of any court or governmental agency or body in
                 Australia is required for the execution and delivery by the
                 Company of this Agreement, the Indenture or the Terms
                 Agreement or any Delayed Delivery Contract or for the
                 consummation by the Company of the transactions contemplated
                 hereby or thereby.  The execution and delivery of the this
                 Agreement, any Delayed Delivery Contract and the Indenture and
                 the consummation by the Company of the transactions
                 contemplated by this Agreement and the Offered Securities and
                 the incurrence of the obligations and consummation of the
                 transactions contemplated herein and therein have been
                 authorized by all necessary corporate action of the Company
                 and will not conflict with or constitute a breach of, or
                 default under, or result in the creation or imposition of any
                 lien, charge or encumbrance upon any property or assets of the
                 Company pursuant to, any contract, indenture, mortgage, loan
                 agreement, note, lease or other




                                     28

                 agreement or instrument to which the Company is a party or by
                 which it may be bound or to which any of the property or
                 assets of the Company is subject, nor will any such action
                 result in any violation of the Memorandum and Articles of
                 Association of the Company or any applicable law,
                 administrative regulation or administrative or court order or
                 decree.

                          (viii)  No stamp duty or similar tax or duty is
                 payable under applicable laws or regulations of Australia in
                 connection with the creation, issuance or delivery of the
                 Offered Securities, the transfer of any of the Offered
                 Securities or with respect to the execution and delivery of
                 this Agreement, the Offered Securities or the Indenture or any
                 document contemplated hereby or thereby.

                          (ix)  It is not necessary under the laws of Australia
                 or any authority or agency therein in order to enable an owner
                 of any interest in the Offered Securities or the Guarantee to
                 enforce its rights under the Offered Securities or the
                 Guarantee or to enable any of the Underwriters to enforce its
                 rights under this Agreement, as the case may be, that it
                 should, as a result solely of its holding or underwriting of
                 the Offered Securities, be licensed, qualified or otherwise
                 entitled to carry on business in Australia or any authority or
                 agency therein; the Offered Securities, the Indenture and this
                 Agreement are in proper legal form under the laws of Australia
                 and any political subdivision thereof or authority or agency
                 therein for the enforcement thereof against the Company
                 therein; and it is not necessary to ensure the legality,
                 validity, enforceability or admissibility in evidence of the
                 Offered Securities, the Indenture or this Agreement in
                 Australia or any authority or agency therein that any of them
                 be filed or recorded or enrolled with any court, authority or
                 agency in, or that any stamp, registration or similar taxes or
                 duties be paid to any court, authority or agency of Australia.

                          (x)  The choice of the laws of the State of New York
                 as the governing law of the Offered Securities, the Indenture
                 and this Agreement is a valid choice of law under the laws of
                 Australia and courts of Australia should honor this choice of
                 law.

                          (xi)  Any final judgment for a definite sum of money
                 rendered by any court of the State of New York or of the
                 United States located in the State of New York




                                     29

                 having jurisdiction under its own domestic laws in respect of
                 any suit, action or proceeding against the Company based upon
                 any instruments or agreements entered into for the
                 consummation of the transactions contemplated in this
                 Agreement, the Indenture, or the Offered Securities would be
                 declared enforceable against the Company by the courts of
                 Australia without reexamination, review of the merits of the
                 cause of action in respect of which the original judgment was
                 given or relitigation of the matters adjudicated upon or
                 payment of any stamp, registration or similar tax or duty,
                 provided that (A) the judgment is consistent with public
                 policy in Australia and any relevant political subdivision,
                 (B) the judgment was not given or obtained by fraud or in a
                 manner contrary to natural justice, (C) the judgment was not
                 based on a clear mistake of law or fact, (D) the judgment was
                 not directly or indirectly for the payment of taxes or other
                 charges of a like nature or of a fine or other penalty, (E)
                 the judgment is for a definite sum, and (F) there has been no
                 prior judgment in another court between the same parties
                 concerning the same issues as are dealt with in the judgment
                 to be enforced in Australia.  Such counsel is not aware of any
                 reason why the enforcement in Australia of such a judgment in
                 respect of any of the instruments or agreements executed for
                 consummation of the transactions contemplated herein or in the
                 Prospectus would be contrary to public policy in Australia or
                 any political subdivision of either of them.

                          (xii)  The Company, and its obligations under this
                 Agreement, the Offered Securities and the Indenture, are
                 subject to civil and commercial law and to suit and neither it
                 nor any of its properties, assets or revenues have any right
                 of immunity, on the grounds of sovereignty, from any legal
                 action, suit or proceeding, from the giving of any relief in
                 any such legal action, suit or proceeding, from setoff or
                 counterclaim, from the jurisdiction of any Australian, New
                 York State or U.S. federal court, as the case may be, from
                 service of process, attachment upon or prior to judgment, or
                 attachment in aid of execution of judgment, or from execution
                 or enforcement of a judgment, or other legal process or
                 proceeding for the giving of any relief or for the enforcement
                 of a judgment, in any such court, with respect to its
                 obligations or liabilities or any other matter under or
                 arising out of or in connection with the Offered Securities,
                 this Agreement or the Indenture; and, to




                                     30
<PAGE>   36
                 the extent that the Company or any of its properties, assets
                 or revenues may have or may hereafter become entitled to any
                 such right of immunity in any such court in which proceedings
                 may at any time be commenced, the Company may waive such right
                 to the extent permitted by law and may consent to such relief
                 and enforcement as provided in this Agreement and the
                 Indenture.

                          (xiii)  It is not necessary under the laws of
                 Australia or any authority or agency therein in order to
                 enable an owner of any interest in the Offered Securities or
                 the Guarantee to enforce its rights under the Offered
                 Securities or the Guarantee or to enable any of the
                 Underwriters to enforce its rights under this Agreement, as
                 the case may be, that it should, as a result solely of its
                 holding or underwriting of the Offered Securities, be
                 licensed, qualified or otherwise entitled to carry on business
                 in Australia or any authority or agency therein; the Offered
                 Securities, the Indenture and this Agreement are in proper
                 legal form under the laws of Australia and any political
                 subdivision thereof or authority or agency therein for the
                 enforcement thereof against the Company therein; and it is not
                 necessary to ensure the legality, validity, enforceability or
                 admissibility in evidence of the Offered Securities, the
                 Indenture or this Agreement in Australia or any authority or
                 agency therein that any of them be filed or recorded or
                 enrolled with any court, authority or agency in, or that any
                 stamp, registration or similar taxes or duties be paid to any
                 court, authority or agency of Australia.

                          (xiv)  Except as disclosed in the Prospectus, no
                 exchange control authorization or any other authorization,
                 approval, consent or license of any governmental authority or
                 agency of or in Australia is required for the payment by the
                 Company of any amounts in United States dollars pursuant to
                 the terms of the Offered Securities or to the Underwriters
                 pursuant to this Agreement.

                          (xv)  The information contained in the Prospectus on
                 page 2 regarding the enforceability of judgments and the
                 Australian exchange controls, and under the caption "Tax
                 Considerations - Australian Law" to the extent that such
                 information constitutes matters of law, summaries of legal
                 matters or legal conclusions, has been reviewed by such
                 counsel and is correct.

                          (xvi) Assuming the Offered Securities are offered and
                 sold in the manner contemplated by this Agreement (including
                 the Terms Agreement) and the Prospectus, the receipt of
                 amounts paid under the Offered Securities in respect of
                 principal, premium or interest by a holder of Offered
                 Securities who is not a "resident of Australia" within the
                 meaning of the Income Tax Assessment Act of 1936 of Australia
                 (the "Tax Act") does not result in the imposition of, or
                 liability for, any income tax, withholding tax, assessment or
                 other charges which are imposed under the Tax Act or by any
                 taxing authority in Australia. This opinion is subject to any
                 subsequent interpretative guidelines issued by the Australian
                 Taxation Office or other department of the Commonwealth
                 Government of Australia which change or alter the manner in
                 which the requirements of section 128F have been interpreted
                 for current purposes.

                 In giving their opinion, Arthur Robinson & Hedderwicks may
         rely as to matters of New York law upon the opinion of Brown & Wood LLP
         furnished pursuant to this Agreement, and as to matters of other
         United States law upon the opinion of Woodard, Hall & Primm, P.C.
         furnished pursuant to this Agreement.

                          (4)     The favorable opinion, dated as of the
         Closing Time, of Brown & Wood LLP, counsel for the Underwriters, with
         respect to the matters set forth in clauses (i) to (ix), 
         inclusive, and (xi) of subsection (b)(1) of this Section.

                          (5)     In giving their opinions required by
         subsection (b)(1), (b)(2), (b)(3) and (b)(4), respectively, of this
         Section 4, Woodard, Hall & Primm, P.C., Zurab S. Kobiashvili, and
         Brown & Wood LLP shall each additionally state that in the course of
         the preparation of the Registration Statement and the Prospectus such
         counsel has considered the information set forth therein in light of
         the matters required to be set forth therein, and has participated in
         conferences with officers and representatives of the Company and the
         Guarantor including their independent public accountants, during the
         course of which the contents of the Registration Statement and the
         Prospectus and related matters were discussed.  Such counsel need not
         independently check the accuracy or completeness of, or otherwise
         verify, and accordingly need not pass upon, and accordingly need not
         assume responsibility for, the accuracy, completeness or fairness of
         the statements contained in the Registration Statement or the
         Prospectus and such counsel may, in good faith, rely as to materiality
         upon the judgment of officers and representatives of the Company and
         the Guarantor.  Such counsel shall additionally state that, however,
         as a result of such consideration and participation, nothing has come
         to such counsel's attention which causes such counsel to believe that
         the Registration Statement, at the time it became effective (or, if an
         amendment to the Registration Statement or an Annual Report on Form
         10-K has been filed by the Guarantor with the Commission subsequent to
         the effectiveness of the Registration Statement, then at the time such
         amendment became effective or at the time of the most recent such
         filing, as the case may be), contained an untrue statement of a
         material fact or omitted to state a material fact required to be
         stated therein or necessary in order to make the statements therein
         not misleading or that the Prospectus or any amendment or supplement
         thereto, at the time the Prospectus was issued at the time any such
         amendment or




                                     32
<PAGE>   38
         supplement was issued or, at the Closing Time included or includes an
         untrue statement of a material fact or omitted or omits to state a
         material fact necessary in order to make the statements therein, in
         the light of the circumstances under which they were made, not
         misleading (it being understood that such counsel need express no
         opinion with respect to the financial statements and engineering
         reports and other financial or engineering data contained in the
         Registration Statement (including the Prospectus) or those parts of
         the Registration Statement which constitute the Form T-1).

                 (c)  At the Closing Time, there shall not have been, since the
         date of the Terms Agreement or since the respective dates as of which
         information is given in the Registration Statement and the Prospectus,
         any material adverse change in the condition, financial or otherwise,
         or in the results of operations, business affairs or business prospects
         of the Company or of the Guarantor and its subsidiaries considered as
         one enterprise, whether or not arising in the ordinary course of
         business, and the Representatives shall have received a certificate of
         (A) the Chief Executive Officer, Vice Chairman, President or Vice
         President and Treasurer, the Assistant Treasurer, the Vice President
         and Chief Financial Officer or principal accounting officer of the
         Company, dated as of the Closing Time, to the effect that (i) there has
         been no such material adverse change with respect to the Company and

         provided to the applicable Underwriter or Underwriters for use in
         confirming sales of the Offered Securities.

                 (d)      (1)     On the date of the Terms Agreement, the
         Underwriters shall have received a letter from Arthur Andersen LLP,
         dated as of the date hereof and in form and substance satisfactory to
         the Underwriters, to the effect that:

                             (i)  They are independent accountants with respect
                 to the Guarantor and its subsidiaries within the meaning of
                 the 1933 Act, the 1933 Act Regulations, the 1934 Act and the
                 1934 Act Regulations.

                            (ii)  It is their opinion that the consolidated
                 financial statements and supporting schedule(s) included or
                 incorporated by reference in the Registration Statement and
                 the Prospectus and audited by them and covered by their
                 opinions therein comply in form in all material respects with
                 the applicable accounting requirements of the 1933 Act, the
                 1933 Act Regulations, the 1934 Act and the 1934 Act
                 Regulations.

                           (iii)  They have performed specified procedures, not
                 constituting an audit, including a reading of the latest
                 available interim financial statements of the Guarantor and
                 its indicated subsidiaries, a reading of the minute books of
                 the Guarantor and such subsidiaries since the end of the most
                 recent fiscal year with respect to which an audit report has
                 been issued, inquiries of and discussions with certain
                 officials of the Guarantor and such subsidiaries responsible
                 for financial and accounting matters with respect to the
                 unaudited consolidated financial statements included or
                 incorporated by reference in the Registration Statement and
                 the Prospectus and the latest available interim unaudited
                 financial statements of the Guarantor and its subsidiaries,
                 and such other inquiries and procedures as may be specified in
                 such letter, and on the basis of such inquiries and
                 procedures, nothing came to their attention that caused them
                 to believe that: (A) any material modifications should be made
                 to the unaudited consolidated financial statements of the
                 Guarantor and its subsidiaries included or incorporated by
                 reference in the Registration Statement and the Prospectus for
                 them to be in conformity with generally accepted accounting
                 principles in the United States, (B) the unaudited
                 consolidated financial statements of the Guarantor and its
                 subsidiaries included or incorporated by reference in the
                 Registration Statement and the




                                     34
<PAGE>   40
                 Prospectus do not comply as to form in all material respects
                 with the applicable accounting requirements of the 1934 Act
                 and the 1934 Act Regulations or (C) at a specified date not
                 more than three days prior to the date of such letter, there
                 was any change in the consolidated capital stock, any increase
                 in consolidated long-term debt or any decrease in the
                 consolidated net current assets or consolidated net assets of
                 the Guarantor and its subsidiaries, in each case as compared
                 with the amounts shown on the most recent consolidated balance
                 sheet of the Guarantor and its subsidiaries included or
                 incorporated by reference in the Registration Statement and
                 the Prospectus or, during the period from the date of such
                 balance sheet to a specified date not more than three days
                 prior to the date of such letter, there were any decreases, as
                 compared with the corresponding period in the preceding year,
                 in consolidated revenues or in the total or per-share amounts
                 of income before extraordinary items or of net income of the
                 Guarantor and its subsidiaries, except in all instances for
                 changes, increases or decreases that the Registration
                 Statement and the Prospectus disclose have occurred or may
                 occur or except for such exceptions enumerated in such letter
                 as shall have been agreed to by the Underwriters and the
                 Guarantor.

                            (iv)  They have performed specified procedures, not
                 constituting an audit, set forth in their letter, based upon
                 which nothing came to their attention that caused them to
                 believe that the unaudited pro forma consolidated condensed
                 financial statements, if any, included or incorporated by
                 reference in the Registration Statement or the Prospectus do
                 not comply as to form in all material respects with the
                 applicable accounting requirements of Rule 11-02 of Regulation
                 S-X and that the pro forma adjustments have not been properly
                 applied to the historical amounts in the compilation of those
                 statements.

                             (v)  In addition to the audit referred to in their
                 opinions and the limited procedures referred to in clauses
                 (iii) and (iv) above, they have carried out certain specified
                 procedures, not constituting an audit, with respect to certain
                 amounts, percentages and financial information which are
                 included or incorporated by reference in the Registration
                 Statement and the Prospectus and which are specified by the
                 Underwriters, and have found such amounts, percentages and
                 financial information to be in agreement with the




                                     35
<PAGE>   41
                 relevant accounting, financial and other records of the
                 Guarantor and its subsidiaries identified in such letter.

                          (2)     At the Closing Time, the Underwriters shall
                 have received from Arthur Andersen LLP, a letter, dated as of
                 the Closing Time, to the effect that they reaffirm the
                 statements made in the letter furnished pursuant to subsection
                 (d)(1) of this Section, except that the specified date
                 referred to shall be a date not more than three days prior to
                 the Closing Time.

                 (e)  At the Closing Time, counsel for the Underwriters shall
         have been furnished with such documents and opinions as they may
         reasonably require for the purpose of enabling them to pass upon the
         issuance and sale of the Offered Securities and the Guarantee as
         herein contemplated and related proceedings or in order to evidence
         the accuracy and completeness of any of the representations and
         warranties, or the fulfillment of any of the conditions, herein
         contained; and all proceedings taken by the Company and the Guarantor
         in connection with the issuance and sale of the Offered Securities as
         herein and in the Terms Agreement contemplated shall be satisfactory
         in form and substance to the Representatives.

                 (f)  In the event that the Terms Agreement provides for Option
         Securities and the Underwriters exercise their option pursuant to
         Section 2(b) hereof to purchase all or any portion of the Option
         Securities, the representations and warranties of the Company and the
         Guarantor contained herein and the statements in any certificates
         furnished by the Company and the Guarantor hereunder shall be true and
         correct as of each Date of Delivery, and the Underwriters shall have
         received:

                          (1)  Unless the Date of Delivery is the Closing Time,
         a certificate, dated such Date of Delivery, of the Chief Executive
         Officer, President or Vice President and the Treasurer, the Assistant
         Treasurer, the principal financial officer or principal accounting
         officer of the Guarantor, in their capacities as such, confirming that
         the certificate delivered at the Closing Time pursuant to Section 4(c)
         hereof remains true and correct as of such Date of Delivery.

                          (2)  The favorable opinion of Woodard, Hall & Primm,
         P.C., counsel for the Company and the Guarantor, Zurab S. Kobiashvili,
         General Counsel for the Guarantor, and Arthur Robinson & Hedderwicks,
         Australian Counsel for the Company, in each case, in form and
         substance satisfactory to




                                     36
<PAGE>   42
         counsel for the Underwriters, dated such Date of Delivery, relating to
         the Option Securities and otherwise substantially to the same effect
         as the opinions required by subsections (1), (2) and (3) of Section
         4(b) hereof.

                          (3)     The favorable opinion of Brown & Wood LLP,
         counsel for the Underwriters, dated such Date of Delivery, relating to
         the Option Securities and otherwise to the same effect as the opinion
         required by subsections (4) and (5) to Section 4(b) hereof.

                          (4)     Unless the Date of Delivery is the Closing
         Time, a letter from Arthur Andersen LLP, in form and substance
         satisfactory to the Underwriters and dated such Date of Delivery,
         substantially the same in scope and substance as the letter furnished
         to the Underwriters at the Closing Time pursuant to Section 4(d)
         hereof, except that the "specified date" in the letter shall be a date
         not more than three days prior to such Date of Delivery.

         If any condition specified in this Section shall not have been
fulfilled when and as required to be fulfilled, this Agreement may be
terminated by the Representatives by notice to the Company and the Guarantor at
any time at or prior to the Closing Time, and such termination shall be without
liability of any party to any other party except as provided in Section 5.

<PAGE>   44
of-pocket expenses, including the reasonable fees and disbursements of counsel
for the Underwriters.

         SECTION 6.  Indemnification.  (a) The Company and the Guarantor agree,
jointly and severally, to indemnify and hold harmless each Underwriter and each
person, if any, who controls any Underwriter within the meaning of Section 15
of the 1933 Act as follows:

         (i) against any and all loss, liability, claim, damage and expense
         whatsoever, as incurred, arising out of any untrue statement or
         alleged untrue statement of a material fact contained in the
         Registration Statement (or any amendment thereto), including any Rule
         462(b) Registration Statement, including information deemed to be part
         of the Registration Statement pursuant to Rule 430A(b) of the 1933 Act
         Regulations, if applicable, or the omission or alleged omission
         therefrom of a material fact required to be stated therein or
         necessary to make the statements therein not misleading or arising out
         of any untrue statement or alleged untrue statement of a material fact
         included in any preliminary prospectus or the Prospectus (or any
         amendment or supplement thereto) or the omission or alleged omission
         therefrom of a material fact necessary in order to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading, unless such untrue statement or omission or such
         alleged untrue statement or omission was made in reliance upon and in
         conformity with written information furnished to the Company or the
         Guarantor by an Underwriter expressly for use in the Registration
         Statement (or any amendment thereto) or such preliminary prospectus or
         the Prospectus (or any amendment or supplement thereto);

         (ii) against any and all loss, liability, claim, damage and expense
         whatsoever, as incurred, to the extent of the aggregate amount paid in
         settlement of any litigation, or investigation or proceeding by any
         governmental agency or body, commenced or threatened, or of any claim
         whatsoever based upon any such untrue statement or omission, or any
         such alleged untrue statement or omission; provided that such
         settlement is effected with the written consent of the Company or the
         Guarantor, which consent shall not be unreasonably withheld; and

         (iii) against any and all expense whatsoever, as incurred (including
         the fees and expenses of counsel chosen by such Underwriter),
         reasonably incurred in investigating, preparing or defending against
         any litigation, or any investigation or proceeding by any governmental
         agency or




                                     39
<PAGE>   45
         body, commenced or threatened, or any claim whatsoever based upon any
         such untrue statement or omission, or any such alleged untrue
         statement or omission, to the extent that any such expense is not paid
         under (i) or (ii) above.

         (b)     Each Underwriter agrees, severally and not jointly, to
indemnify and hold harmless the Company, the Guarantor, their respective
directors, each of their officers who signed the Registration Statement, and
each person, if any, who controls the Company or the Guarantor within the
meaning of Section 15 of the 1933 Act against any and all loss, liability,
claim, damage and expense described in the indemnity contained in subsection
(a) of this Section, but only with respect to untrue statements or omissions,
or alleged untrue statements or omissions, made in the Registration Statement
(or any amendment thereto), any Rule 462(b) Registration Statement or any
preliminary prospectus or the Prospectus (or any amendment or supplement
thereto) in reliance upon and in conformity with written information furnished
to the Guarantor by such Underwriter expressly for use in the Registration
Statement (or any amendment thereto), any Rule 462(b) Registration Statement or
any preliminary prospectus or the Prospectus (or any amendment or supplement
thereto).

         (c)     Each indemnified party shall give notice as promptly as
reasonably practicable to each indemnifying party of any action commenced
against it in respect of which indemnity may be sought hereunder, but failure
to so notify an indemnifying party shall not relieve it from any liability
which it may have otherwise than on account of this indemnity agreement.  If
any such claim or action shall be brought against an indemnified party, and it
shall notify the indemnifying party thereof, the indemnifying party shall be
entitled to participate therein and to the extent that it wishes, jointly with
any other similarly notified indemnifying party, to assume the defense thereof
with counsel reasonably satisfactory to the indemnified party.  After notice
from the indemnifying party to the indemnified party of its election to assume
the defense of such claim or action, the indemnifying party shall not be liable
to the indemnified party under this Section for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that
each Underwriter shall have the right to employ counsel to represent jointly
the Underwriters and their respective controlling persons who may be subject to
liability arising out of any claim in respect of which indemnity may be sought
by the Underwriters against the Company or the Guarantor under this Section if,
in the judgment of any of the Underwriters, it is advisable for such
Underwriter or Underwriters and controlling persons to be jointly represented
by separate counsel, and in that event the fees and expenses of such




                                     40
<PAGE>   46
   
separate counsel shall be paid by the Company and the Guarantor, acting jointly
and severally.  In no event shall the indemnifying parties be liable for the
fees and expenses of more than one counsel (in addition to any local counsel)
separate from their own counsel for all indemnified parties in connection with
any one action or separate but similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances.  No
indemnifying party shall, without the prior written consent of the indemnified
parties (which shall not unreasonably be withheld), settle or compromise or
consent to the entry of any judgment with respect to any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever in respect of which indemnification or
contribution could be sought under this Section 6 or Section 7 hereof (whether
or not the indemnified parties are actual or potential parties thereto), unless
such settlement, compromise or consent (i) includes an unconditional release of
each indemnified party from all liability arising out of such litigation,
investigation, proceeding or claim and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act by or on behalf of
any indemnified party.
    

         (d)     For purposes of this Section 6, all references to the
Registration Statement, any preliminary prospectus or the Prospectus, or any
amendment or supplement to any of the foregoing, shall be deemed to include,
without limitation, any electronically transmitted copies thereof, including,
without limitation, any copies filed with the Commission pursuant to EDGAR.

         SECTION 7.  Contribution.  If the indemnification provided for in
Section 6 hereof is for any reason unavailable to or insufficient to hold
harmless an indemnified party in respect of any losses, liabilities, claims,
damages or expenses referred to therein, then each indemnifying party shall
contribute to the aggregate amount of such losses, liabilities, claims, damages
and expenses incurred by such indemnified party, as incurred, (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company and the Guarantor on the one hand and the Underwriters on the other
hand from the offering of the Offered Securities pursuant to this Agreement or
(ii) if the allocation provided by clause (i) is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause (i) above but also the relative fault of the
Company and the Guarantor on the one hand and of the Underwriters on the other
hand in connection with the statements or omissions which resulted in such
losses, liabilities, claims, damages or expenses, as well as any other relevant
equitable considerations.  The relative benefits




                                     41
<PAGE>   47
received by the Company and the Guarantor on the one hand and the Underwriters
on the other hand in connection with the offering of the Offered Securities
pursuant to this Agreement shall be deemed to be in the same respective
proportions as the total net proceeds from the offering of the Offered
Securities pursuant to this Agreement (before deducting expenses) received by
the Company and the total commission or underwriting discount received by each
Underwriter, in each case as set forth on the cover of the Prospectus
Supplement, bear to the aggregate initial public offering price of the Offered
Securities sold to or through such Underwriter as set forth on such cover.  The
relative fault of the Company and the Guarantor on the one hand and the
Underwriters on the other hand shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or
the omission or alleged omission to state a material fact relates to
information supplied by the Company or the Guarantor or by the Underwriters and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.  The Company, the Guarantor
and the Underwriters agree that it would not be just and equitable if
contribution pursuant to this Section 7 were determined by pro rata allocation
(even if the Underwriters were treated as one entity for such purpose) or by
any other method of allocation which does not take account of the equitable
considerations referred to above in this Section 7.  The aggregate amount of
losses, liabilities, claims, damages and expenses incurred by an indemnified
party and referred to above in this Section 7 shall be deemed to include any
legal or other expenses reasonably incurred by such indemnified party in
investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged
untrue statement or omission or alleged omission.  Notwithstanding the
provisions of this Section 7, no Underwriter shall be required to contribute
any amount in excess of the amount by which the total price at which the
Offered Securities sold to or through such Underwriter were offered to the
public exceeds the amount of any damages which such Underwriter has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission.  No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the 1933 Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.  For purposes of this Section 7, each person, if any, who
controls an Underwriter within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act shall have the same rights to contribution as such
Underwriter, and each director of the Company or the Guarantor, each officer of
the Company or the Guarantor who signed the Registration Statement, and each
person, if any, who controls the




                                     42
<PAGE>   48
Company or the Guarantor within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act shall have the same rights to contribution as the
Company or the Guarantor, as the case may be.  The Underwriters' respective
obligations to contribute pursuant to this Section 7 are several in proportion
to the principal amount of Offered Securities sold to or through each
Underwriter and not joint.

         SECTION 8.  Representations, Warranties and Agreements to Survive
Delivery.  All representations, warranties and agreements contained in this
Agreement or in certificates of officers of the Company and the Guarantor
submitted pursuant hereto or thereto shall remain operative and in full force
and effect, regardless of any investigation made by or on behalf of any
Underwriter or controlling person of an Underwriter, or by or on behalf of the
Company or the Guarantor, and shall survive each delivery of and payment for
any Offered Securities.

         SECTION 9.  Termination.

         (a)     The Representatives may terminate this Agreement immediately
upon notice to the Company, at any time at or prior to the Closing Time if (i)
there has been, since the date of the Terms Agreement or since the respective
dates as of which information is given in the Registration Statement, any
material adverse change in the condition, financial or otherwise, or in the
results of operations, business affairs or business prospects of the Company or
the Guarantor and its subsidiaries considered as one enterprise, whether or not
arising in the ordinary course of business, or (ii) there shall have occurred
any material adverse change in the financial markets in Australia or the United
States or any outbreak or escalation of hostilities or other national or
international calamity or crisis or any material adverse change or prospective
material adverse change in exchange controls or taxation in Australia or the
United States the effect of which is such as to make it, in the judgment of the
Representatives, impracticable to market the Offered Securities or enforce
contracts for the sale of the Offered Securities, or (iii) trading in any
securities of the Guarantor has been suspended by the Commission or a national
securities exchange, or if trading generally on either the American Stock
Exchange or the New York Stock Exchange shall have been suspended, or minimum
or maximum prices for trading have been fixed, or maximum ranges for prices for
securities have been required, by either of said exchanges or by order of the
Commission or any other governmental authority, or if a banking moratorium
shall have been declared by Australian, U.S. Federal, New York or Texas
authorities or if a banking moratorium shall have been declared by the relevant
authorities in the country or countries of origin of any foreign currency or
currencies in which the Offered Securities are




                                     43
<PAGE>   49
denominated or payable, or (iv) the rating assigned by any nationally
recognized statistical rating organization to any debt securities of the
Company or the Guarantor as of the date of the Terms Agreement shall have been
lowered since that date or if any such rating organization shall have publicly
announced that it has under surveillance or review, with possible negative
implications, its rating of any debt securities of the Company or the
Guarantor, as the case may be, or (v) there shall have come to the attention of
the Representatives any facts that would cause them to reasonably believe that
the Prospectus, at the time it was required to be delivered to a purchaser of
the Offered Securities, included an untrue statement of a material fact or
omitted to state a material fact necessary in order to make the statements
therein, in light of the circumstances existing at the time of such delivery,
not misleading.  As used in this Section 9, the term "Prospectus" means the
Prospectus in the form first provided to the applicable Underwriter or
Underwriters for use in confirming sales of the related Offered Securities.

         (b)     If this Agreement is terminated pursuant to this Section, such
termination shall be without liability of any party to any other party, except
to the extent provided in Section 5.  Notwithstanding any such termination, (i)
the covenants set forth in Section 3(b), (d), and (e) with respect to any
offering of Offered Securities shall remain in effect so long as any
Underwriter owns any such Offered Securities purchased from the Company
pursuant to this Agreement and during the period when the Prospectus is
required to be delivered in connection with sales of the Offered Securities and
(ii) the covenants set forth in Section 3(c), (g), (h) and, if applicable, (i),
the provisions of Section 5, the indemnity agreement set forth in Section 6,
the contribution provisions set forth in Section 7 and the provisions of
Sections 8, 11, 12 and 13 shall remain in effect.

         SECTION 10.  Default.  If one or more of the Underwriters shall fail
at the Closing Time or a Date of Delivery to purchase the Immediate Delivery
Offered Securities which it or they are obligated to purchase under this
Agreement (the "Defaulted Securities"), then the Representatives shall have the
right, within 24 hours thereafter, to make arrangements for one or more of the
non-defaulting Underwriters, or any other underwriters, to purchase all, but
not less than all, of the Defaulted Securities in such amounts as may be agreed
upon and upon the terms herein set forth.  If, however, during such 24 hours
the Representatives shall not have completed such arrangements for the purchase
of all of the Defaulted Securities, then:

                 (a)      if the amount of Defaulted Securities does not exceed
         10% of the amount of Immediate Delivery Offered Securities to be
         purchased on such date, each of the




                                     44
<PAGE>   50
         non-defaulting Underwriters shall be obligated, severally and not
         jointly, to purchase the full amount thereof in the proportions that
         their respective underwriting obligations hereunder bear to the
         underwriting obligations of all non-defaulting Underwriters, or

                 (b)      if the amount of Defaulted Securities exceeds 10% of
         the number of Immediate Delivery Offered Securities to be purchased on
         such date, this Agreement or, with respect to any Date of Delivery
         which occurs after the Closing Time, the obligation of the
         Underwriters to purchase and of the Company to sell the Option
         Securities to be purchased and sold on such Date of Delivery shall
         terminate without liability on the part of any non-defaulting
         Underwriter.

         No action taken pursuant to this Section 10 shall relieve any
defaulting Underwriter from liability in respect of its default.

         In the event of any such default which does not result in a
termination of this Agreement or, in the case of a Date of Delivery which is
after the Closing Time, which does not result in a termination of the
obligation of the Underwriters to purchase and the Company to sell the relevant
Option Securities, as the case may be, any of the Representatives, the Company
or the Guarantor shall have the right to postpone the Closing Time or the
relevant Date of Delivery, as the case may be, for a period not exceeding seven
days in order to effect any required changes in the Registration Statement or
the Prospectus or in any other documents or arrangements.  As used herein, the
term "Underwriter" includes any person substituted for an Underwriter under
this Section 10.

   
         SECTION 11.  Notices.  All notices and other communications hereunder
shall be in writing, either delivered by hand, by mail or by telex, telecopier
or telegram, and any such notice shall be effective when received at the address
specified in this Section 11.  Notices to the Underwriters shall be directed as

Agreement may from time to time designate another address to receive notice

         SECTION 12.  Parties.  This Agreement shall inure to the benefit of
and be binding upon the Underwriters, the Company and the Guarantor and their
respective successors.  Nothing expressed or mentioned in this Agreement is
intended or shall be construed to give any person, firm or corporation, other
than the parties hereto and their respective successors and the controlling
persons and officers and directors referred to in Sections 6 and 7 and their
heirs and legal representatives, any legal or equitable right, remedy or claim
under or in respect of this Agreement or any provision herein contained.  This
Agreement and all conditions and provisions hereof are intended to be for the
sole and exclusive benefit of the parties hereto and their respective
successors and said controlling persons and officers and directors and their
heirs and legal representatives, and for the benefit of no other person, firm
or corporation.  No purchaser of Offered Securities from any Underwriter shall
be deemed to be a successor by reason merely of such purchase.

         SECTION 13.  Governing Law.  This Agreement and all the rights and
obligations of the parties hereto shall be governed by and construed in
accordance with the laws of the State of New York applicable to agreements made
and to be performed in such State.

         SECTION 14.  Consent to Jurisdiction; Appointment of Agent to Accept
Service of Process.

                 (a)      The Company irrevocably consents and agrees, for the
         benefit of the Holders from time to time of the Offered Securities,
         the Underwriters and the other persons referred to in Section 12 that
         any legal action, suit or proceeding against it with respect to its
         obligations, liabilities or any other matter arising out of or in
         connection with this Agreement, the Guarantee or any Offered
         Securities may be brought in the courts of the State of New York, or
         the courts of the United States of America located in The City of New
         York and, until all amounts due and to become due in respect of the
         Guarantee and all the Offered Securities have been paid, or until any
         such legal action, suit or proceeding commenced prior to such payment
         has been concluded, hereby irrevocably consents and submits to the
         non-exclusive jurisdiction of each such court in personam, generally
         and unconditionally with respect to any action, suit or proceeding for
         itself and in respect of its properties, assets and revenues.

                 (b)  The Company hereby irrevocably designates, appoints, and
         empowers CT Corporation, with offices currently at 1633 Broadway, New
         York, New York 10019, as its designee, appointee and agent to receive,
         accept and




                                     46
<PAGE>   52
         acknowledge for and on its behalf service of any and all legal
         process, summons, notices and documents that may be served in any
         action, suit or proceeding brought against the Company in any such
         United States federal or state court with respect to its obligations,
         liabilities or any other matter arising out of or in connection with
         this Agreement, the Guarantee or any Debt Securities and that may be
         made on such designee, appointee and agent in accordance with legal
         procedures prescribed for such courts.  If for any reason such
         designee, appointee and agent hereunder shall cease to be available to
         act as such, the Company agrees to designate a new designee, appointee
         and agent in The City of New York on the terms and for the purposes of
         this Section 14 reasonably satisfactory to each of the
         Representatives.  The Company further hereby irrevocably consents and
         agrees to the service of any and all legal process, summons, notices
         and documents in any such action, suit or proceeding against the
         Company by serving a copy thereof upon the relevant agent for service
         of process referred to in this Section 14 (whether or not the
         appointment of such agent shall for any reason prove to be ineffective
         or such agent shall accept or acknowledge such service) or by mailing
         copies thereof by registered or certified air mail, postage prepaid,
         to the Company at its address specified in or designated pursuant to
         this Agreement, with a copy (similarly mailed) to CT Corporation, 1633
         Broadway, New York, New York 10019.  The Company agrees that the
         failure of any such designee, appointee and agent to give any notice
         of such service to it shall not impair or affect in any way the
         validity of such service or any judgment rendered in any action or
         proceeding based thereon.  Nothing herein shall in any way be deemed
         to limit the ability of the holders of the Securities, the
         Underwriters and the other persons referred to in Section 12 to serve
         any such legal process, summons, notices and documents in any other
         manner permitted by applicable law or to obtain jurisdiction over the
         Company or bring actions, suits or proceedings against the Company in
         such other jurisdictions, and in such manner, as may be permitted by
         applicable law.  The Company hereby irrevocably and unconditionally
         waives, to the fullest extent permitted by law, any objection that it
         may now or hereafter have to the laying of venue of any of the
         aforesaid actions, suits or proceedings arising out of or in
         connection with this Agreement brought in the United States federal
         courts located in The City of New York or the courts of the State of
         New York located in The City of New York and hereby further
         irrevocably and unconditionally waives and agrees not to plead or
         claim in any such court that any such action, suit or proceeding
         brought in any such court has been brought in an inconvenient forum.




                                     47
<PAGE>   53
                 (c)  The provisions of this Section 14 shall survive any
         termination of this Agreement, in whole or in part.

         SECTION 15.  Foreign Taxes.  All payments by the Company or the
Guarantor to an Underwriter hereunder, including the Terms Agreement, shall be
made free and clear of, and without deduction or withholding for or on account
of, any and all present and future income, stamp or other taxes, levies,
imposts, duties, charges, fees deductions or withholdings, now or hereafter
imposed, levied, collected, withheld or assessed by Australia or any other
jurisdiction in which the Company or the Guarantor has a branch or an office
from which payment is made or deemed to be made, excluding any such tax imposed
in respect of amounts due hereunder (i) by reason of such Underwriter having
some connection with Australia or such other jurisdiction, other than its
participation as dealer hereunder, or (ii) by reason of any income or franchise
tax on the overall net income of an Underwriter imposed by the United States of
America or by the State of New York or any political subdivision of the United
States of America or of the State of New York or by any jurisdiction of which
such Underwriter is a resident, or (iii) if any Underwriter would not be liable
or subject to such impost, levy, collection, withholding or deduction if it
were to make a declaration of nonresidence or other similar claim for exemption
but fails to do so, or (iv) pursuant to any back-up withholding taxes
applicable to any payments to a noncorporate person acting as agent hereunder
who fails to furnish an accurate taxpayer identification number (all such
non-excluded taxes, "Taxes").  If the Company or the Guarantor is prevented by
operation of law or otherwise from paying, causing to be paid or remitting that
portion of amounts payable represented by Taxes withheld or deducted, then
amounts payable under the Terms Agreement or this Agreement shall be increased
to such amount as is necessary to yield and remit to the Underwriter an amount
which, after deduction of all Taxes (including all Taxes payable on such
increased payments), equals the amount that would have been payable if no Taxes
applied.

         SECTION 16.  Jurisdictional Restrictions on Sale of Offered
Securities.  

                 (a)     Each Underwriter severally agrees to use its reasonable
         efforts to ensure that (i) no Offered Securities issued by the Company
         shall be offered or sold directly or indirectly, in the Commonwealth of
         Australia or any state or territory thereof or to a corporation,
         partnership, trust or other entity organized under the laws of, or
         resident in, the Commonwealth of Australia and (ii) no documents in
         relation to an offer of Securities shall be distributed in Australia or
         in or from a state or territory thereof. 




                                     48
<PAGE>   54
         (b)     Each Underwriter further severally represents and agrees (i) 
                 that it will not sell any Offered Securities in circumstances
                 where it knows or has reasonable grounds to believe, without
                 any independent investigation, that the Offered Securities or
                 an interest in or right in respect of the Offered Securities,
                 was being, or would later be, acquired either directly or
                 indirectly by a resident of Australia or by an entity
                 specified in Annex B to the Terms Agreement and (ii) as to
                 such additional matters as may be set forth in the Terms
                 Agreement.

         (c)     Each Underwriter agrees to provide the Company, within 14 days
                 of receipt of a written request from the Company, at the
                 expense of the Company, such information which reasonably
                 relates to any Offered Securities as is ordinarily required
                 for the purposes of obtaining an exemption from Australian
                 interest withholding tax under Section 128F of the Tax Act or
                 which reasonably relates to a request from the Australian
                 Taxation Office for specific information, but only to the
                 extent such information may be provided in accordance with
                 applicable law (and in the latter case the Company's request
                 shall be accompanied by satisfactory evidence of such request
                 from the Australian Taxation Office).  Notwithstanding the
                 foregoing, nothing shall oblige an Underwriter to disclose the
                 identity of any investor to whom it sells Offered Securities.

         SECTION 17.  Waiver of Immunities.  To the extent that the Company or
the Guarantor or any of their 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 Agreement (including the Terms Agreement), the Indenture
(including the Guarantee) or the Offered Securities, the Company and the
Guarantor hereby irrevocably and unconditionally waive, and agree not to plead
or claim, any such immunity and consent to such relief and enforcement.




                                     49
<PAGE>   55
         SECTION 18.  Judgment Currency.  The Company and the Guarantor agree
to indemnify each of the Underwriters against any loss incurred by such
Underwriter as a result of any judgment or order being given or made for any
amount due hereunder and such judgment or order being 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 rate of exchange at which such Underwriter
is able to purchase United States dollars with the amount of the Judgment
Currency actually received by such Underwriter.  The foregoing indemnity shall
constitute a separate and independent obligation of each of the Company and the
Guarantor and shall continue in full force and effect notwithstanding any such
judgment or order as aforesaid.  The term "rate of exchange" shall include any
premiums and costs of exchange payable in connection with the purchase of, or
conversion into, the relevant currency.

         SECTION 19.  Counterparts.  Any Terms Agreement may be executed in one
or more counterparts and, if executed in more than one counterpart, the
executed counterparts thereof shall constitute a single instrument.

the Trustee to take any action under any provision of this Indenture, the

of any such application or request as to which the furnishing of such documents
or any of them is specifically required by any provision of this Indenture
relating to such particular application or request, no additional certificate or
opinion need be furnished.


                 Section 103.     Form of Documents Delivered to Trustee.

                 In any case where several matters are required to be certified
by, or covered by an opinion of, any specified Person, it is not necessary that
all such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

                 Any certificate or opinion of an officer of the Guarantor or
the Company, as applicable, may be based, insofar as it relates to legal
matters, upon an Opinion of Counsel, unless such officer knows, or in the
exercise of reasonable care should know, that the opinion with respect to the
matters upon which his certificate or opinion is based are erroneous.  Any such
Opinion of Counsel may be based, insofar as it relates to factual matters, upon
a certificate or opinion of, or representations by, an officer or officers of
the Guarantor or the Company, as applicable, stating that the information with
respect to such factual matters is in the possession of the Guarantor or the
Company, as applicable, unless such counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to such matters are erroneous.

                 Where any Person is required to make, give or execute two or
more applications, requests, consents, certificates, statements, opinions or
other instruments under this Indenture or any Security, they may, but need not,
be consolidated and form one instrument.


                 Section 104.     Acts of Holders.

                 (a)  Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by or pursuant to 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, but only if, Securities of a series
are issuable as





                                       14
<PAGE>   23
Bearer Securities, any request, demand, authorization, direction, notice,
consent, waiver or other action provided in or pursuant to this Indenture to be
given or taken by Holders of Securities 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 any meeting of Holders of Securities of such series duly called and
held in accordance with the provisions of Article Fifteen, or a combination of
such instruments and any such record.  Except as herein otherwise expressly
provided, such action shall become effective when such instrument or
instruments or record or both are delivered to the Trustee and, where it is
hereby expressly required, to the Guarantor or the Company, as the case may be.
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 or so voting at any such
meeting.  Proof of execution of any such instrument or of a writing appointing
any such agent, or of the holding by any Person of a Security, shall be
sufficient for any purpose of this Indenture and (subject to Section 315 of the
Trust Indenture Act) conclusive in favor of the Trustee, the Guarantor or the
Company, and any agent of the Trustee or the Company or the Guarantor, 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.

                 Without limiting the generality of this Section 104, unless
otherwise provided in or pursuant to this Indenture, a Holder, including a U.S.
Depository that is a Holder of a global Security, may make, give or take, by a
proxy, or proxies, duly appointed in writing, any request, demand,
authorization, direction, notice, consent, waiver or other Act provided in or
pursuant to this Indenture to be made, given or taken by Holders, and a U.S.
Depository that is a Holder of a global Security may provide its proxy or
proxies to the beneficial owners of interests in any such global Security
through such U.S. Depository's standing instructions and customary practices.

                 The Trustee shall fix a record date for the purpose of
determining the Persons who are beneficial owners of interest in any permanent
global Security held by a U.S. Depository entitled under the procedures of such
U.S.  Depository to make, give or take, by a proxy or proxies duly appointed in
writing, any request, demand, authorization, direction, notice, consent, waiver
or other Act provided in or pursuant to this Indenture to be made, given or
taken by Holders.  If such a record date is fixed, the Holders on such record
date or their duly appointed proxy or proxies, and only such Persons, shall be
entitled to make, give or take such request, demand, authorization, direction,
notice, consent, waiver or other Act, whether or not such Holders remain
Holders after such record date.  No such request, demand, authorization,
direction, notice, consent, waiver or other Act shall be valid or  effective if
made, given or taken more than 90 days after such record date.

                 (b)  The fact and date of the execution by any Person of any
such instrument or writing may be proved in any reasonable manner which the
Trustee deems sufficient and in accordance with such reasonable rules as the
Trustee may determine; and the Trustee may in any instance require further
proof with respect to any of the matters referred to in this Section.





                                       15
<PAGE>   24
                 (c)  The ownership, principal amount and serial numbers of
Registered Securities held by any Person, and the date of the commencement and
the date of the termination of holding the same, shall be proved by the
Security Register.

                 (d)  The ownership, principal amount and serial numbers of
Bearer Securities held by any Person, and the date of the commencement and the
date of the termination 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 reasonably acceptable to the
Trustee, the Guarantor and the Company, wherever situated, if such certificate
shall be deemed by the Company,the Guarantor and 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 or affidavit of the
Person holding such Bearer Securities, if such certificate or affidavit is
deemed by the Company, the Guarantor and the Trustee to be satisfactory.  The
Trustee, the Company and the Guarantor may assume that such ownership of any
Bearer Security continues until (1) another certificate or affidavit bearing a
later date issued in respect of the same Bearer Security is produced, or (2)
such Bearer Security is produced to the Trustee by some other Person, or (3)
such Bearer Security is surrendered in exchange for a Registered Security, or
(4) such Bearer Security is no longer Outstanding.  The ownership, principal
amount and serial numbers of Bearer Securities held by the Person so executing
such instrument or writing and the date of the commencement and the date of the
termination of holding the same may also be proved in any other manner which
the Trustee, the Guarantor and the Company deem sufficient.

                 (e)  If the Company or the Guarantor shall solicit from the
Holders of any Registered Securities any request, demand, authorization,
direction, notice, consent, waiver or other Act, the Company may at its option
(but is not obligated to), by Board Resolution, fix in advance a record date
for the determination of Holders of Registered Securities entitled to give such
request, demand, authorization, direction, notice, consent, waiver or other
Act.  If such a record date is fixed, such request, demand, authorization,
direction, notice, consent, waiver or other Act may be given before or after
such record date, but only the Holders of Registered Securities of record at
the close of business on such record date shall be deemed to be Holders for the
purpose of determining whether Holders of the requisite proportion of
Outstanding Securities have authorized or agreed or consented to such request,
demand, authorization, direction, notice, consent, waiver or other Act, and for
that purpose the Outstanding Securities shall be computed as of such record
date; provided that no such authorization, agreement or consent by the Holders
of Registered Securities shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture not later than six
months after the record date.

                 (f)  Any request, demand, authorization, direction, notice,
consent, waiver or other Act by 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 or suffered to be done by the Trustee, any Security
Registrar, any Paying Agent or the Company or the Guarantor in reliance
thereon, whether or not notation of such Act is made upon such Security.

                 Section 105.     Notices, etc. to Trustee, the Company and the
Guarantor.

                 Any request, demand, authorization, direction, notice,
consent, waiver or other Act of Holders or other document provided or permitted
by this Indenture to be made upon, given or furnished to, or filed with,

                 (a)  the Trustee by any Holder, the Guarantor or 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 Trustee Administration Department,
         or

                 (b) the Guarantor or the Company by the Trustee or 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 Guarantor or the Company, as applicable,
         addressed to the attention of its Treasurer 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, the Guarantor or the Company, as applicable.


                 Section 106.     Notice to Holders of Securities; Waiver.

                 Except as otherwise expressly provided in or pursuant to this
Indenture, where this Indenture provides for notice to Holders of Securities of
any event,

                 (a)  such notice shall be sufficiently given to Holders of
         Registered Securities if in writing and mailed, first-class postage
         prepaid, to each Holder of a Registered Security affected by such
         event, at his address 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

                 (b)  such notice shall be sufficiently given to Holders of
         Bearer Securities, if any, if published in an Authorized Newspaper in
         The City of New York and, if such Securities are then listed on any
         stock exchange outside the United States, in an Authorized Newspaper
         in such city as the Company shall advise the Trustee that such stock
         exchange so requires, on a Business Day at least twice, the first such
         publication to be not earlier than the earliest date and the second
         such publication not later than the latest date prescribed for the
         giving of such notice.

                 In any case where 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.  Any notice which is mailed in the manner
herein provided shall be conclusively presumed to have been duly given or
provided.  In case by reason of the suspension of regular mail service or by





                                       17
<PAGE>   26
reason of any other cause it shall be impracticable to give such notice by
mail, then such notification as shall be made with the approval of the Trustee
shall constitute a sufficient notification for every purpose hereunder.

                 In case by reason of the suspension of publication 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 given with the approval of the Trustee shall constitute sufficient
notice to such Holders for every purpose hereunder.  Neither 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 mailed to Holders of Registered Securities as provided above.

                 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 of Securities 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 107.     Language of Notices.

                 Any request, demand, authorization, direction, notice,
consent, election or waiver required or permitted under this Indenture shall be
in the English language, except that, if the Company or the Guarantor so
elects, any published notice may be in an official language of the country of
publication.


                 Section 108.     Conflict with Trust Indenture Act.

                 If any provision hereof limits, qualifies or conflicts with
any duties under any required provision of the Trust Indenture Act imposed
hereon by Section 318(c) thereof, such required provision shall control.


                 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 or the
Guarantor, as applicable, shall bind such party's successors and assigns,
whether so expressed or not.

                 Section 111.     Separability Clause.

         In case any provision in this Indenture, any Security, any Coupon or
any Guarantee 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, any Security or any Coupon, or in any
Guarantee, express or implied, shall give to any Person, other than the parties
hereto, any Security Registrar, any Paying Agent and their successors hereunder
and the Holders of Securities or Coupons, any benefit or any legal or equitable
right, remedy or claim under this Indenture.


                 Section 113.     Governing Law.

                 This Indenture, the Securities, any Coupons and the Guarantees
shall be governed by and construed in accordance with the laws of the State of
New York applicable to agreements made or instruments entered into and, in each
case, performed in said state without regard to the conflict of laws principles
thereof.


                 Section 114.     Legal Holidays.

                 Unless otherwise specified in or pursuant to this Indenture or
any Securities, in any case where any Interest Payment Date, Business Day
following any Change in Control Purchase Date or Stated Maturity or Maturity of
any Security shall be a Legal Holiday at any Place of Payment, then
(notwithstanding any other provision of this Indenture, any Security, Coupon or
Guarantee other than a provision in any Security, Coupon or Guarantee that
specifically states that such provision shall apply in lieu hereof) payment
need not be made at such Place of Payment on such date, and no interest shall
accrue on the amount payable on such date or at such time for the period from
and after such Interest Payment Date, Business Day following any Change in
Control Purchase Date, Stated Maturity or Maturity, as the case may be, to the
next succeeding Business Day.

                 Section 115.     Counterparts.

                 This Indenture may be executed in several counterparts, each
of which shall be an original and all of which shall constitute but one and the
same instrument.

                 Section 116.     Judgment Currency.

                 Each of the Company and the Guarantor agrees, to the fullest
extent that it may effectively do so under applicable law, that (a) if for the
purpose of obtaining judgment in any court it is necessary to convert the sum
due in respect of the principal of, or premium or interest, if any, or
Additional Amounts on the Securities of any series (the "Required Currency")
into a currency in which a judgment will be rendered (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 Banking Day
preceding that on which a final unappealable judgment is given and (b) its
obligations under this Indenture to make payments in the Required Currency (i)
shall not be discharged or satisfied by any tender, or any recovery pursuant to
any judgment (whether or not entered in accordance with clause (a)), in any
currency other than the Required Currency, except to the extent that such
tender or recovery shall result in the actual receipt, by the payee, of the
full amount of the Required Currency expressed to be payable in respect of such
payments, (ii) shall be enforceable as an alternative or additional cause of
action for the purpose of recovering in the Required Currency the amount, if
any, by which such actual receipt shall fall short of the full amount of the
Required Currency so expressed to be payable and (iii) shall not be affected by
judgment being obtained for any other sum due under this Indenture.  For
purposes of the foregoing, "New York Banking Day" means any day except a
Saturday, Sunday or a legal holiday in The City of New York or a day on which
banking institutions in The City of New York are authorized or obligated by
law, regulation or executive order to be closed.

thereon as may, consistently herewith, be determined by the officers executing

         Guarantees to be endorsed on the Securities shall, subject to Section
201, be in substantially the form set forth below:

GUARANTEE

         For value received, Apache Corporation, a corporation organized under

         which term includes any successor corporation under the Indenture
         referred to in the Security upon which this Guarantee is endorsed),
         hereby irrevocably and unconditionally guarantees to the Holder of the

         behalf of the Trustee and such Holder the due and punctual payment of
         the principal of, and any premium, and interest on, and any Additional
         Amounts with respect to, such Security, and any other amount due and
         payable pursuant to the terms of the Indenture or payments referred to
         therein if any, when and as the same shall become due and payable,

         of such Security and of the Indenture referred to therein. In case of
         the failure of Apache Finance Pty Ltd, a proprietary company with
         limited liability organized under the laws of the Australian Capital
         Territory, Australia (herein called the "Company," which term includes
         any successor corporation under such Indenture), punctually to make
         any such payment of principal, or any premium or interest on or any
         Additional Amounts with respect to such Security, the Guarantor hereby
         agrees to cause any such payment to be made punctually when and as the
         same shall become due and payable, whether at the Stated Maturity or
         by declaration of acceleration, call for redemption or otherwise, and
         as if such payment were made by the Company. The Guarantor hereby
         agrees that its obligations hereunder shall be as if it were principal
         debtor and not merely surety, and shall be absolute and unconditional,
         irrespective of, and shall be unaffected by, any invalidity,
         irregularity or unenforceability of such Security or such Indenture,
         any failure to enforce the provisions of such Security or such
         Indenture, or any waiver, modification or indulgence granted to the
         Company with respect thereto, by the holder of such Security or the
         Trustee or any other circumstance which may otherwise constitute a
         legal or equitable discharge of a surety or guarantor. The Guarantor
         hereby waives the benefits of division and discussion, diligence,
         presentment, demand of payment, filing of claims with a court in the
         event of merger, insolvency or bankruptcy of the Company, any right to
         require a proceeding first against the Company, protest or notice with
         respect to such Security or the indebtedness evidenced thereby and all
         demands whatsoever, and covenants that this Guarantee will not be
         discharged except by strict and complete performance of the
         obligations contained in such Security and this Guarantee. The
         Guarantor hereby agrees that, in the event of a default in payment of
         principal of, or any premium or interest on, or any Additional Amounts
         with respect to, such Security, or default in any sinking fund or
         analogous payment referred to therein, legal proceedings may be
         instituted by the Trustee on behalf of, or by, the Holder of such
         Security, on the terms and conditions set forth in  the Indenture,
         directly against the Guarantor to enforce this Guarantee without first
         proceeding against the Company.

         The Guarantor shall be subrogated to all rights of the Holder of such
         Security and the Trustee against the Company in respect of any amounts
         paid to such Holder by the Guarantor on account of such Security
         pursuant to the provisions of this Guarantee or the Indenture;
         provided, however, that the Guarantor shall not be entitled to
         enforce, or to receive any payments arising out of or based upon, such
         right of subrogation until the principal of, and any premium and
         interest on, and any Additional Amounts required with respect to, all
         Securities issued under such Indenture shall have been paid in full.

         No reference herein to such Indenture and no provision of this
         Guarantee or of such Indenture shall alter or impair the guarantee of
         the Guarantor, which is absolute and unconditional, of the due and
         punctual payment of principal of, any premium and interest on, and any
         Additional Amounts required with respect to, the Security upon which
         this Guarantee is endorsed.

         This Guarantee shall not be valid or obligatory for any purpose until
         the certificate of authentication of the Security upon which this
         Guarantee is endorsed shall have been manually executed by or on
         behalf of the Trustee under such Indenture.

         All terms used in this Guarantee which are defined in such Indenture
         shall have the meanings assigned to them in such Indenture.

         This Guarantee shall be deemed to be a contract made under the laws of
         the State of New York, and for all purposes shall be governed by and
         construed in accordance with the laws of the State of New York.

         This Guarantee is an unsecured obligation of the Guarantor, and ranks
         pari passu with all other unsubordinated indebtedness of the
         Guarantor.

         IN WITNESS WHEREOF, the Guarantor has caused this Guarantee to be duly
         executed under its corporate seal and dated the date on the face
         hereof.

                 Section 204.     Securities in Global Form.

                 Unless otherwise provided in or pursuant to this Indenture or
any Securities, the Securities shall not be issuable in temporary or permanent
global form.  If Securities of a series shall be issuable in global form, any
such Security may provide that it or any number of such Securities shall
represent the aggregate amount of all Outstanding Securities of such series (or
such lesser amount as is permitted by the terms thereof) from time to time
endorsed thereon and may also provide that the aggregate amount of Outstanding
Securities represented thereby may from time to time be increased or reduced to
reflect exchanges.  Any endorsement of any Security in global form to reflect
the amount, or any increase or decrease in the amount, or changes in the rights
of Holders, of Outstanding Securities represented thereby shall be made in such
manner and by such Person or Persons as shall be specified therein or in the
Company Order or Guarantor Order to be delivered pursuant to Section 303 or 304
with respect thereto.  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 therein or in the applicable Company Order or
Guarantor Order.  If a Company Order or Guarantor Order pursuant to Section 303
or 304 has been, or simultaneously is, delivered, any instructions by the
Company or the Guarantor with respect to a Security in global form shall be in
writing but need not be accompanied by or contained in an Officers' Certificate
and need not be accompanied by an Opinion of Counsel.

responsibilities under this Indenture in relation to such Securities and any
Coupons appertaining thereto, and the Guarantees endorsed thereon, the Trustee
shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of

         authorized officers of the Company to the Trustee for authentication
         pursuant to this Indenture, and 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
         legally valid and binding obligations of the Company, enforceable
         against the Company in accordance with their terms, except as
         enforcement thereof may be subject to or limited by bankruptcy,
         insolvency, reorganization, moratorium, arrangement, fraudulent
         conveyance, fraudulent transfer or other similar laws relating to or
         affecting creditors' rights generally, and subject to general
         principles of equity (regardless of whether enforcement is sought in a
         proceeding in equity or at law) and will entitle the Holders thereof
         to the benefits of this Indenture, including the Guarantee; such
         Opinion of Counsel need express no opinion as to the availability of
         equitable remedies;

                  (c)      the Guarantees, when executed under the Guarantor's
         corporate seal and attested by duly authorized officers of the
         Guarantor and endorsed upon a Security that is authenticated and
         delivered by the Trustee and issued by the Company in the manner and
         subject to any condition specified in such Opinion of Counsel, will
         constitute legally valid and binding obligations of the Guarantor,
         enforceable against the Guarantor in accordance with its terms, except
         as enforcement thereof may be subject to or limited by bankruptcy,
         insolvency, reorganization, moratorium, arrangement, fraudulent
         conveyance, fraudulent transfer or other similar laws relating to or
         affecting creditors' rights generally, and subject to general
         principles of equity (regardless of whether enforcement is sought in a
         proceeding in equity or at law) and will entitle the Holders to the
         benefits of this Indenture; such Opinion of Counsel need express no
         opinion as to the availability of equitable remedies;

                 (d)      all laws and requirements in respect of the execution
         and delivery by the Company of such Securities and Coupons, if any,
         have been complied with; and

                 (e)      this Indenture has been qualified under the Trust
         Indenture Act; and

         (2)     Officers' Certificates of the Company and the Guarantor
stating that, in each case, to the best knowledge of the Persons executing such
certificate, no event which is, or after notice or lapse of time would become,
an Event of Default with respect to any of the Securities or the Guarantees
shall have occurred and be continuing.

                 If all the Securities of any series are not to be issued at
one time, it shall not be necessary to deliver an Opinion of Counsel and
Officers' Certificates at the time of issuance of each Security, but such
opinion and certificate, with appropriate modifications, shall be delivered at
or before the time of issuance of the first Security of such series.  After any
such first delivery, any separate request by the Company that the Trustee
authenticate Securities of such series for original issue will be deemed to be
a certification by the Company and the Guarantor that all conditions precedent
provided for in this Indenture relating to authentication and delivery of such
Securities continue to have been complied with.

<PAGE>   39
                 The Trustee shall not be required to authenticate or to cause
an Authenticating Agent to authenticate any 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 or if the Trustee,
being advised by counsel, determines that such action may not lawfully be
taken.

                 Each Registered Security shall be dated the date of its
authentication.  Each Bearer Security and any Bearer Security in global form
shall be dated as of the date specified in or pursuant to this Indenture.

                 No Security or Guarantee or Coupon 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 a certificate of
authentication substantially in the form provided for in Section 202 or 611
executed by or on behalf of the Trustee or by the Authenticating Agent by the
manual signature of one of its authorized officers.  Such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder.  Except as
permitted by Section 306 or 307, the Trustee shall not authenticate and deliver
any Bearer Security or related Guarantee unless all Coupons appertaining
thereto then matured have been detached and canceled.


                 Section 304.     Temporary Securities.

                 Pending the preparation of definitive Securities, the Company
may execute and deliver to the Trustee and, upon Company Order and Guarantor
Order, the Trustee shall authenticate and deliver, in the manner provided in
Section 303, temporary Securities in lieu thereof 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 or pursuant to this Indenture, in bearer form with one or more
Coupons or without Coupons and having endorsed thereon Guarantees of the
Guarantor substantially of the tenor of the definitive Guarantees, and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities or Guarantees may determine, as
conclusively evidenced by their execution of such Securities or Guarantees, as
the case may be.  Such temporary Securities may be in global form.

                 Except in the case of temporary Securities in global form,
which shall be exchanged in accordance with the provisions thereof, if
temporary Securities are issued, the Company shall cause definitive Securities
to be prepared without unreasonable delay.  After the preparation of definitive
Securities of the same series and containing terms and provisions that are
identical to those of any temporary Securities, such temporary Securities shall
be exchangeable for such definitive Securities with Guarantees of the Guarantor
endorsed thereon upon surrender of such temporary Securities at an Office or
Agency for such Securities, without charge to any Holder thereof.  Upon
surrender for cancellation of any one or more temporary Securities (accompanied
by any unmatured Coupons





                                       31
<PAGE>   40
appertaining thereto), the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of authorized denominations of the same series and
containing identical terms and provisions, each with a Guarantee of the
Guarantor endorsed thereon; provided, however, that no definitive Bearer
Security, except as provided in or pursuant to this Indenture, shall be
delivered in exchange for a temporary Registered Security; and provided,
further, that a definitive Bearer Security shall be delivered in exchange for a
temporary Bearer Security only in compliance with the conditions set forth in
or pursuant to this Indenture.  Unless otherwise provided in or pursuant to
this Indenture with respect to a temporary global Security, 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.


                 Section 305.     Registration, Transfer and Exchange.

                 With respect to the Registered Securities of each series, if
any, the Company shall cause to be kept a register (each such register being
herein sometimes referred to as the "Security Register") at an Office or Agency
for such series in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of the Registered
Securities of such series and of transfers of the Registered Securities of such
series.  Such Office or Agency shall be the "Security Registrar" for that series
of Securities.  Unless otherwise specified in or pursuant to this Indenture or
the Securities, the Trustee shall be the initial Security Registrar for each
series of Securities.  The Company shall have the right to remove and replace
from time to time the Security Registrar for any series of Securities; provided
that no such removal or replacement shall be effective until a successor
Security Registrar with respect to such series of Securities shall have been
appointed by the Company and shall have accepted such appointment by the
Company.  In the event that the Trustee shall not be or shall cease to be
Security Registrar with respect to a series of Securities, it shall have the
right to examine the Security Register for such series at all reasonable times.
There shall be only one Security Register for each series of Securities.

                 Upon surrender for registration of transfer of any Registered
Security of any series at any Office or Agency for such 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 denominated as authorized in or pursuant to this Indenture,
of a like aggregate principal amount bearing a number not contemporaneously
outstanding and containing identical terms and provisions, having Guarantees
duly endorsed thereon.

                 At the option of the Holder, Registered Securities of any
series may be exchanged for other Registered Securities of the same series
containing identical terms and provisions, in any authorized denominations, and
of a like aggregate principal amount, upon surrender of the Securities to be
exchanged at any Office or Agency for such series.  Whenever any Registered
Securities are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Registered Securities which the
Holder making the exchange is entitled to receive having Guarantees duly
endorsed thereon.




                                       32
<PAGE>   41
                 If provided in or pursuant to this Indenture, with respect to
Securities of any series, at the option of the Holder, Bearer Securities of
such series may be exchanged for Registered Securities of such series
containing identical terms, denominated as authorized in or pursuant to this
Indenture and in the same aggregate principal amount, upon surrender of the
Bearer Securities to be exchanged at any Office or Agency for such series, 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, the Guarantor and the Trustee 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, the Guarantor 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 Bearer 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 the amount of such payment; provided,
however, that, except as otherwise provided in Section 1002, interest
represented by Coupons shall be payable only upon presentation and surrender of
those Coupons at an Office or Agency for such series located outside the United
States.  Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such Office or Agency for such series in exchange for a
Registered Security of such series and like tenor after the close of business
at such Office or Agency 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 date for payment of Defaulted Interest, such Bearer
Security shall be surrendered without the Coupon relating to such Interest
Payment Date or proposed date of payment, as the case may be (or, if such
Coupon is so surrendered with such Bearer Security, such Coupon shall be
returned to the Person so surrendering the Bearer Security), and interest or
Defaulted Interest, as the case may be, shall 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 shall
be payable only to the Holder of such Coupon when due in accordance with the
provisions of this Indenture.

                 If provided in or pursuant to this Indenture with respect to
Securities of any series, at the option of the Holder, Registered Securities of
such series may be exchanged for Bearer Securities upon such terms and
conditions as may be provided in or pursuant to this Indenture with respect to
such series.

                 Whenever any Securities are surrendered for exchange as
contemplated by the immediately preceding two paragraphs, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities, having
endorsed thereon Guarantees of the Guarantor which the Holder making the
exchange is entitled to receive.

                 Notwithstanding the foregoing, except as otherwise provided in
or pursuant to this Indenture, any global Security shall be exchangeable for
definitive Securities only if (i) the Depository is at any time unwilling,
unable or ineligible to continue as Depository and a successor depository is





                                       33
<PAGE>   42
not appointed by the Company within 90 days of the date the Company is so
informed in writing, (ii) the Company executes and delivers to the Trustee a
Company Order to the effect that such global Security shall be so exchangeable,
or (iii) an Event of Default has occurred and is continuing with respect to the
Securities.  If the beneficial owners of interests in a global Security are
entitled to exchange such interests for definitive Securities as the result of
an event described in clause (i), (ii) or (iii) of the preceding sentence, 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 in such form and denominations as are required by
or pursuant to this Indenture, and of the same series, containing identical
terms and in aggregate principal amount equal to the principal amount of such
global Security, executed by the Company.  On or after the earliest date on
which such interests may be so exchanged, such global Security shall be
surrendered from time to time by the U.S. Depository or such other Depository
as shall be specified in the Company Order with respect thereto, and in
accordance with instructions given to the Trustee and the U.S. Depository or
such other Depository, as the case may be (which instructions shall be in
writing but need not be contained in or accompanied by an Officers' Certificate
or be accompanied by an Opinion of Counsel), 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
as described above without charge.  The Trustee shall authenticate and make
available for delivery, in exchange for each portion of such surrendered global
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 global Security to be exchanged, which (unless such Securities are not
issuable both as Bearer Securities and as Registered Securities, in which case
the definitive Securities exchanged for the global Security shall be issuable
only in the form in which the Securities are issuable, as provided in or
pursuant to this Indenture) shall be in the form of Bearer Securities or
Registered Securities, or any combination thereof, as shall be specified by the
beneficial owner thereof, but subject to the satisfaction of any certification
or other requirements to the issuance of Bearer Securities; 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 the same series to be
redeemed and ending on the relevant Redemption Date; and provided, further,
that (unless otherwise provided in or pursuant to this Indenture) no Bearer
Security delivered in exchange for a portion of a global Security shall be
mailed or otherwise delivered to any location in the United States.  Promptly
following any such exchange in part, such global Security shall be returned by
the Trustee to such Depository or the U.S. Depository, as the case may be, or
such other Depository or U.S. Depository 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 global Security after the close of
business at the Office or Agency for such Security where such exchange occurs
on or after (i) any Regular Record Date for such Security and before the
opening of business at such Office or Agency on the next Interest Payment Date,
or (ii) any Special Record Date for such Security 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, interest shall 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 shall be payable on such
Interest Payment Date or proposed date for payment, as the case may be, only to
the Person to whom interest in respect of such portion of such global Security
shall be payable in accordance with the provisions of this Indenture.

<PAGE>   43
                 All Securities issued upon any registration of transfer or
exchange of Securities and all Guarantees endorsed thereon shall be the valid
obligations of the Company or the Guarantor, as the case may be, evidencing the
same debt and entitling the Holders thereof to the same benefits under this
Indenture as the Securities and Guarantees endorsed thereon surrendered upon
such registration of transfer or exchange.

                 Every Registered Security presented or surrendered for
registration of transfer or for exchange or redemption shall (if so required by
the Company or the Security Registrar for such Security) be duly endorsed, or
be accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar for such Security duly executed by the
Holder thereof or his attorney duly authorized in writing.

                 No service charge shall be made for any registration of
transfer or exchange, or redemption of Securities, but the Company may require
payment of a sum sufficient to cover any tax or other governmental charge.

                 Except as otherwise provided in or pursuant to this Indenture,
the Company shall not be required (i) to issue, register the transfer of or
exchange any Securities during a period beginning at the opening of business 15
days before the day of the selection for redemption of Securities of like tenor
and the same series under Section 1103 and ending at the close of business on
the day of such selection, or (ii) to register the transfer of or exchange any
Registered Security so selected for redemption in whole or in part, except in
the case of any Security to be redeemed in part, the portion thereof not to be
redeemed, or (iii) to exchange any Bearer Security so selected for redemption
except, to the extent provided with respect to such Bearer Security, that such
Bearer Security may be exchanged for a Registered Security of like tenor and
the same series, provided that such Registered Security shall be immediately
surrendered for redemption with written instruction for payment consistent with
the provisions of this Indenture or (iv) to issue, register the transfer of or
exchange any Security which, in accordance with its terms, has been surrendered
for repayment at the option of the Holder, except the portion, if any, of such
Security not to be so repaid.

                 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, subject to the
provisions of this Section 306, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a new Security of the same series
containing identical terms and of like principal amount, having endorsed
thereon the Guarantee of the Guarantor and bearing a number not
contemporaneously outstanding, with Coupons appertaining thereto corresponding
to the Coupons, if any, appertaining to the surrendered Security.

                 If there be delivered to the Company, the Guarantor and to the
Trustee (i) evidence to their satisfaction of the destruction, loss or theft of
any Security or Coupon, and (ii) such security or indemnity as may be required
by them to save each of them and any agent of either of them





                                       35
<PAGE>   44
harmless, then, in the absence of notice to the Company, the Guarantor or the
Trustee that such Security or Coupon has been acquired by a bona fide
purchaser, the Company shall execute and, upon Company Request the Trustee
shall authenticate and deliver, in exchange for or in lieu of any such
mutilated, 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
containing identical terms and of like principal amount having endorsed thereon
the Guarantee of the Guarantor 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.

                 Notwithstanding the foregoing provisions of this Section 306,
in case any 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 or Coupon; provided,
however, that principal of, any premium or interest on or any Additional
Amounts with respect to any Bearer Securities shall, except as otherwise
provided in Section 1002, be payable only at an Office or Agency for such
Securities located outside the United States and, unless otherwise provided in
or pursuant to this Indenture, any interest on Bearer Securities and any
Additional Amounts with respect to such interest shall be payable only upon
presentation and surrender of the Coupons appertaining thereto.

                 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, with any Coupons appertaining thereto, and
the Guarantee of the Guarantor endorsed thereon, 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 a separate obligation of the Company and the Guarantor,
respectively, whether or not the destroyed, lost or stolen Security and Coupons
appertaining thereto or the destroyed, lost or stolen Coupon 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 such
series and any Coupons and related Guarantees duly issued hereunder.

                 The provisions of this Section, as amended or supplemented
pursuant to this Indenture with respect to particular Securities or generally,
shall be 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 and Certain Additional Amounts;
                          Rights to Interest and Certain Additional Amounts
                          Preserved.

                 Unless otherwise provided in or pursuant to this Indenture,
any interest on and any Additional Amounts with respect to any Registered
Security which shall be payable, and are punctually paid or duly provided for,
on any Interest Payment Date shall be paid to the Person in whose name such
Security (or one or more Predecessor Securities) is registered as of the close
of business on the Regular Record Date for such interest.  Unless otherwise
provided in or pursuant to this Indenture, in case a Bearer Security is
surrendered in exchange for a Registered Security after the close of business
at an Office or Agency for such Security on any Regular Record Date therefor
and before the opening of business at such Office or Agency on the next
succeeding Interest Payment Date therefor, such Bearer Security shall be
surrendered without the Coupon relating to such Interest Payment Date and
interest shall not be payable on such Interest Payment Date in respect of the
Registered Security issued in exchange for such Bearer Security, but shall be
payable only to the Holder of such Coupon when due in accordance with the
provisions of this Indenture.

                 Unless otherwise provided in or pursuant to this Indenture,
any interest on and any Additional Amounts with respect to any Registered
Security which shall be payable, but shall not be punctually paid or duly
provided for, on any Interest Payment Date for such Registered Security (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
thereof on the relevant Regular Record Date by virtue of having been such
Holder; and such Defaulted Interest may be paid by the Company or the
Guarantor, at its election in each case, as provided in Clause (1) or (2)
below:

         (1)     The Company or the Guarantor may elect to make payment of any
Defaulted Interest to the Person in whose name such Registered Security (or a
Predecessor Security thereof) shall be 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 or the Guarantor shall notify the
Trustee in writing of the amount of Defaulted Interest proposed to be paid on
such Registered Security and the date of the proposed payment, and at the same
time the Company or the Guarantor, as the case may be, 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 on or prior to the date of the proposed payment,
such money when so deposited to be held in trust for the benefit of the Person
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 the Holder of such Registered Security (or a
Predecessor Security thereof) 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,





                                       37
<PAGE>   46
in the name and at the expense of the Company cause a similar notice to be
published at least once in an Authorized Newspaper of general circulation in the
Borough of Manhattan, The City of New York, 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 mailed as aforesaid, such Defaulted Interest shall be paid
to the Person in whose name such Registered Security (or a Predecessor Security
thereof) shall be registered at the close of business on such Special Record
Date and shall no longer be payable pursuant to the following clause (2). In
case a Bearer Security is surrendered at the Office or Agency for such Security
in exchange for a Registered Security after the close of business at such Office
or Agency on 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
Defaulted Interest and Defaulted Interest shall not be payable on such proposed
date of payment in respect of the Registered Security issued in exchange for
such Bearer Security, but shall be payable only to the Holder of such Coupon
when due in accordance with the provisions of this Indenture.

         (2)     The Company or the Guarantor may make payment of any Defaulted
Interest in any other lawful manner not inconsistent with the requirements of
any securities exchange on which such Security may be listed, and upon such
notice as may be required by such exchange, if, after notice given by the
Company or the Guarantor to the Trustee of the proposed payment pursuant to
this Clause, such payment shall be deemed practicable by the Trustee.

                 Unless otherwise provided in or pursuant to this Indenture or
the Securities of any particular series, at the option of the Company, interest
on Registered Securities that bear interest may be paid by mailing a check to
the address of the Person entitled thereto as such address shall appear in the
Security Register or by transfer to an account maintained by the payee with a
bank located in the United States.

                 Subject to the foregoing provisions of this Section and
Section 305, each Security delivered under this Indenture upon registration of
transfer of or 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 Guarantor, the Trustee and any agent
of the Company, the Guarantor or the Trustee may treat the Person in whose name
such Registered Security is registered in the Security Register as the owner of
such Registered Security for the purpose of receiving payment of principal of,
any premium and (subject to Sections 305 and 307) interest on and any
Additional Amounts with respect to such Registered Security and for all other

to such Registered Security shall be overdue, and neither the Company, the
Guarantor nor the Trustee or any agent of the Company, the Guarantor or the
Trustee shall be affected by notice to the contrary.

                 The Company, the Guarantor, the Trustee and any agent of the
Company, the Guarantor or the Trustee may treat the bearer of any Bearer
Security or 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 any payment with respect to
such Security or Coupon shall be overdue, and neither the Company, the
Guarantor nor the Trustee or any agent of the Company, the Guarantor or the
Trustee shall be affected by notice to the contrary.

                 No holder of any beneficial interest in any global Security
held on its behalf by a Depository shall have any rights under this Indenture
with respect to such global Security, and such Depository may be treated by the
Company, the Guarantor, the Trustee, and any agent of the Company, the
Guarantor or the Trustee as the owner of such global Security for all purposes
whatsoever.  None of the Company, the Guarantor, the Trustee, any Paying Agent
or the Security Registrar will have any responsibility or liability for any
aspect of the records relating to or payments made on account of beneficial
ownership interests of a global Security or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

                 All Securities and Coupons surrendered for payment,
redemption, registration of transfer or exchange shall, if surrendered to any
Person other than the Trustee, be delivered to the Trustee, and any such

to the Trustee for any such purpose, shall be canceled promptly by the Trustee.
The Company or the Guarantor may at any time deliver to the Trustee for
cancellation any Securities or Coupons previously authenticated and delivered
hereunder which the Company or the Guarantor may have acquired in any manner
whatsoever, and all Securities or Coupons so delivered shall be canceled
promptly by the Trustee.  No Securities or Coupons shall be authenticated in
lieu of or in exchange for any Securities canceled as provided in this Section,
except as expressly permitted by or pursuant to this Indenture.  All canceled
Securities and Coupons held by the Trustee shall be destroyed by the Trustee,
unless by a Company Order or Guarantor Order, the Company or the Guarantor
directs their return to it.

                 Section 310.     Computation of Interest.

                 Except as otherwise provided in or pursuant to this Indenture

of a 360-day year of twelve 30-day months.

                    SATISFACTION AND DISCHARGE OF INDENTURE

                 Section 401.     Satisfaction and Discharge.

                 Upon the direction of the Company by a Company Order or the
Guarantor by a Guarantor Order, this Indenture shall cease to be of further
effect with respect to any series of Securities specified in such Company Order
or Guarantor Order and any Coupons appertaining thereto, and the Trustee, on
receipt of a Company Order or Guarantor Order, at the expense of the Company
and the Guarantor, shall execute proper instruments acknowledging satisfaction
and discharge of this Indenture as to such series, when

                 (1)      either

                          (a)     all Securities of such series theretofore
         authenticated and delivered and all Coupons appertaining thereto
         (other than (i) Coupons appertaining to Bearer Securities of such
         series surrendered in exchange for Registered Securities of such
         series and maturing after such exchange whose surrender is not
         required or has been waived as provided in Section 305, (ii)
         Securities and Coupons of such series which have been destroyed, lost
         or stolen and which have been replaced or paid as provided in Section
         306, (iii) Coupons appertaining to Securities of such series called
         for redemption and maturing after the relevant Redemption Date whose
         surrender has been waived as provided in Section 1107, and (iv)

         thereafter repaid to the Company or the Guarantor or discharged from
         such trust, as provided in Section 1003) have been delivered to the
         Trustee for cancellation; or

                          (b)     all Securities of such series and, in the
         case of (i) or (ii) below, any Coupons appertaining thereto not
         theretofore delivered to the Trustee for cancellation

                          (i)     have become due and payable, or

                          (ii)    will become due and payable at their Stated
                 Maturity within one year, or

                 are to be called for redemption within one year under
                 arrangements satisfactory to the Trustee for the giving of
                 notice of redemption by the Trustee in the name, and at the
                 expense, of the Company,

         and the Company or the Guarantor, in the case of (i), (ii) or (iii)
         above, has deposited or caused to be deposited with the Trustee as
         trust funds in trust for such purpose, money in the





                                       40
<PAGE>   49
         Currency in which such Securities are payable in an amount sufficient
         to pay and discharge the entire indebtedness on such Securities and
         any Coupons appertaining thereto not theretofore delivered to the
         Trustee for cancellation, including the principal of, any premium and
         interest on, and any Additional Amounts with respect to such
         Securities and any Coupons appertaining thereto, to the date of such
         deposit (in the case of Securities which have become due and payable)
         or to the Maturity thereof, as the case may be;

                 (2)      the Company or the Guarantor, as the case may be, has
         paid or caused to be paid all other sums payable hereunder by the
         Company with respect to the Outstanding Securities of such series and
         any Coupons appertaining thereto; and

                 (3)      the Company or the Guarantor, as the case may be, 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 as to
         such series have been complied with.

                 In the event there are Securities of two or more series
hereunder, the Trustee shall be required to execute an instrument acknowledging
satisfaction and discharge of this Indenture only if requested to do so with
respect to Securities of such series as to which it is Trustee and if the other
conditions thereto are met.

                 Notwithstanding the satisfaction and discharge of this
Indenture with respect to any series of Securities, the obligations of the
Company and the Guarantor to the Trustee under Section 606 and, if money shall
have been deposited with the Trustee pursuant to subclause (b) of clause (1) of
this Section, the obligations of the Trustee, the Guarantor and the Company
with respect to the Securities of such series under Sections 305, 306, 403,
1002 and 1003, with respect to the payment of Additional Amounts, if any, with
respect to such Securities as contemplated by Section 1004 (but only to the
extent that the Additional Amounts payable with respect to such Securities
exceed the amount deposited in respect of such Additional Amounts pursuant to
Section 401(1)(b)), shall survive.


                 Section 402.     Defeasance and Covenant Defeasance.

                 (1)      Unless, pursuant to Section 301, either or both of
(i) defeasance of the Securities of or within a series under clause (2) of this
Section 402, or (ii) covenant defeasance of the Securities of or within a
series under clause (3) of this Section 402 shall not be applicable with
respect to the Securities of such series, then such provisions, together with
the other provisions of this Section 402 (with such modifications thereto as
may be specified pursuant to Section 301 with respect to any Securities), shall
be applicable to such Securities and any Coupons appertaining thereto, and the
Company may at its option by Board Resolution or Officers' Certificate, at any
time, with respect to such Securities and any Coupons appertaining thereto,
elect to have Section 402(2) or Section 402(3) be applied to such Outstanding
Securities and any Coupons appertaining thereto upon compliance with the
conditions set forth below in this Section 402.





                                       41
<PAGE>   50
                 (2)      Upon the Company's exercise of the above option
applicable to this Section 402(2) with respect to any Securities of or within a
series, the Company and the Guarantor shall be deemed to have been discharged
from their respective obligations with respect to such Outstanding Securities
and any Coupons appertaining thereto, and with respect to the Guarantees
endorsed thereon,  on the date the conditions set forth in clause (4) of this
Section 402 are satisfied (hereinafter, "defeasance").  For this purpose, such
defeasance means that the Company and the Guarantor shall be deemed to have
paid and discharged the entire Indebtedness represented by such Outstanding
Securities and any Coupons appertaining thereto, and such corresponding
Guarantees, which shall thereafter be deemed to be "Outstanding" only for the
purposes of clause (5) of this Section 402 and the other Sections of this
Indenture referred to in clauses (i) and (ii) below, and to have satisfied all
of its other obligations under such Securities and any Coupons appertaining
thereto and this Indenture insofar as such Securities and any Coupons
appertaining thereto are concerned (and the Trustee, at the expense of the
Company, shall execute proper instruments acknowledging the same), except for
the following which shall survive until otherwise terminated or discharged
hereunder:  (i) the rights of Holders of such Outstanding Securities and any
Guarantees and Coupons appertaining thereto to receive, solely from the trust
fund described in clause (4) of this Section 402 and as more fully set forth in
such Section, payments in respect of the principal of (and premium, if any) and
interest, if any, on, and Additional Amounts, if any, with respect to, such
Securities and any Coupons appertaining thereto when such payments are due,
(ii) the obligations of the Company and the Trustee with respect to such
Securities under Sections 305, 306, 1002 and 1003, with respect to the payment
of Additional Amounts, if any, on such Securities as contemplated by Section
1004 (but only to the extent that the Additional Amounts payable with respect
to such Securities exceed the amount deposited in respect of such Additional
Amounts pursuant to Section 401(4)(a) below), and any obligations of the
Guarantor relating to a surviving obligation of the Company, (iii) the rights,
powers, trusts, duties and immunities of the Trustee hereunder and (iv) this
Section 402.  The Company may exercise its option under this Section 402(2)
notwithstanding the prior exercise of its option under clause (3) of this
Section 402 with respect to such Securities and any Coupons appertaining
thereto.

                 (3)      Upon the Company's exercise of the above option
applicable to this Section 402(3) with respect to any Securities of or within a
series, the Company and the Guarantor shall be released from their respective
obligations under Sections 1005 and 1006, and, to the extent specified pursuant
to Section 301, any other covenant applicable to such Securities or the
Guarantees endorsed thereon, with respect to such Outstanding Securities and
any Coupons appertaining thereto on and after the date the conditions set forth
in clause (4) of this Section 402 are satisfied (hereinafter, "covenant
defeasance"), and such Securities and any Coupons appertaining thereto shall
thereafter be deemed to be not "Outstanding" for the purposes of any direction,
waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with any such covenant, but shall continue to be deemed
"Outstanding" for all other purposes hereunder.  For this purpose, such
covenant defeasance means that, with respect to such Outstanding Securities and
any Coupons appertaining thereto and the Guarantees endorsed thereon, the
Company and the Guarantor may omit to comply with, and shall have no liability
in respect of, any term, condition or limitation set forth in any such Section
or such other covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such Section or such other covenant or by
reason of reference in any such





                                       42
<PAGE>   51
Section or such other covenant to any other provision herein or in any other
document and such omission to comply shall not constitute a default or an Event
of Default under Section 501(3) or 501(4) or otherwise, as the case may be,
but, except as specified above, the remainder of this Indenture and such
Securities and Coupons appertaining thereto and the Guarantees endorsed thereon
shall be unaffected thereby.

                 (4)      The following shall be the conditions to application
of clause (2) or (3) of this Section 402 to any Outstanding Securities of or
within a series and any Coupons appertaining thereto and the Guarantees
endorsed thereon:

                 (a)      The Company or the Guarantor shall irrevocably have
         deposited or caused to be deposited with the Trustee (or another
         trustee satisfying the requirements of Section 607 who shall agree to
         comply with the provisions of this Section 402 applicable to it) as
         trust funds in trust for the purpose of making the following payments,
         specifically pledged as security for, and dedicated solely to, the
         benefit of the Holders of such Securities and any Coupons appertaining
         thereto,

                          (1) an amount in Dollars or in such Foreign Currency
                 in which such Securities and any Coupons appertaining thereto
                 are then specified as payable at Stated Maturity, or

                          (2) Government Obligations applicable to such
                 Securities and Coupons appertaining thereto (determined on the
                 basis of the Currency in which such Securities and Coupons
                 appertaining thereto are then specified as payable at Stated
                 Maturity) which through the scheduled payment of principal and
                 interest in respect thereof in accordance with their terms
                 will provide, not later than one day before the due date of
                 any payment of principal of (and premium, if any) and
                 interest, if any, on such Securities and any Coupons
                 appertaining thereto, money in an amount, or

                          (3) a combination thereof,

                 in any case, in an amount, sufficient, without consideration
                 of any reinvestment of such principal and interest, in the
                 opinion of a nationally recognized firm of independent public
                 accountants expressed in a written certification thereof
                 delivered to the Trustee, to pay and discharge, and which
                 shall be applied by the Trustee (or other qualifying trustee)
                 to pay and discharge, the principal of (and premium, if any)
                 and interest, if any, on such Outstanding Securities and any
                 Coupons appertaining thereto on the Stated Maturity of such
                 principal or installment of principal or interest on the day
                 on which such payments are due and payable in accordance with
                 the terms of this Indenture and of such Securities and any
                 Coupons appertaining thereto.

                 (b)      Such defeasance or covenant defeasance shall not
         result in a breach or violation of, or constitute a default under,
         this Indenture or any other material agreement or





                                       43

                  instrument to which the Company or the Guarantor is a party 
         or by which either of them is bound.
         
                 (c)      No Event of Default or event which with notice or
         lapse of time or both would become an Event of Default with respect to
         such Securities and any Coupons appertaining thereto shall have
         occurred and be continuing on the date of such deposit and, with
         respect to defeasance only, at any time during 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).

                 (d)      In the case of an election under clause (2) of this
         Section 402, the Company or the Guarantor shall have delivered to the
         Trustee an Opinion of Counsel stating that (i) the Company or the
         Guarantor has received from the Internal Revenue Service a letter
         ruling, or there has been published by the Internal Revenue Service a
         Revenue Ruling, or (ii) since the date of execution of this Indenture,
         there has been a change in the applicable Federal income tax law, in
         either case to the effect that, and based thereon such opinion shall
         confirm that, the Holders of such Outstanding Securities and any
         Coupons appertaining thereto will not recognize income, gain or loss
         for Federal income tax purposes as a result of such defeasance and
         will be subject to Federal income tax on the same amounts, in the same
         manner and at the same times as would have been the case if such
         defeasance had not occurred.

                 (e)      In the case of an election under clause (3) of this
         Section 402, the Company and the Guarantor shall have delivered to the
         Trustee an Opinion of Counsel to the effect that the Holders of such
         Outstanding Securities and any Coupons appertaining thereto will not
         recognize income, gain or loss for Federal income tax purposes as a
         result of such covenant defeasance and will be subject to Federal
         income tax on the same amounts, in the same manner and at the same
         times as would have been the case if such covenant defeasance had not
         occurred.

                 (f)      The Company and the Guarantor shall have delivered to
         the Trustee an Officers' Certificate and an Opinion of Counsel, each
         stating that all conditions precedent to the defeasance or covenant
         defeasance under clause (2) or (3) of this Section 402 (as the case
         may be) have been complied with.

                 (g)      Notwithstanding any other provisions of this Section
         402(4), such defeasance or covenant defeasance shall be effected in
         compliance with any additional or substitute terms, conditions or
         limitations which may be imposed on the Company or the Guarantor in
         connection therewith pursuant to Section 301.

                 (5)      Subject to the provisions of the last paragraph of
Section 1003, all money and Government Obligations (or other property as may be
provided pursuant to Section 301) (including the proceeds thereof) deposited
with the Trustee (or other qualifying trustee, collectively for purposes





                                       44
<PAGE>   53
of this Section 402(5) and Section 403, the "Trustee") pursuant to clause (4)
of Section 402 in respect of any Outstanding Securities of any series and any
Coupons appertaining thereto shall be held in trust and applied by the Trustee,
in accordance with the provisions of such Securities and any Coupons
appertaining thereto 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 Holders of such Securities and any Coupons
appertaining thereto of all sums due and to become due thereon in respect of
principal (and premium, if any) and interest and Additional Amounts, if any,
but such money need not be segregated from other funds except to the extent
required by law.

                 Unless otherwise specified in or pursuant to this Indenture or
any Security, if, after a deposit referred to in Section 402(4)(a) has been
made, (a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 301 or the terms of such
Security to receive payment in a Currency other than that in which the deposit
pursuant to Section 402(4)(a) has been made in respect of such Security, or (b)
a Conversion Event occurs in respect of the Foreign Currency in which the
deposit pursuant to Section 402(4)(a) has been made, the indebtedness
represented by such Security and any Coupons appertaining thereto and the
Guarantees endorsed thereon shall be deemed to have been, and will be, fully
discharged and satisfied through the payment of the principal of (and premium,
if any), and interest, if any, on, and Additional Amounts, if any, with respect
to, such Security as the same becomes due out of the proceeds yielded by
converting (from time to time as specified below in the case of any such
election) the amount or other property deposited in respect of such Security
into the Currency in which such Security becomes payable as a result of such
election or Conversion Event based on (x) in the case of payments made pursuant
to clause (a) above, the applicable market exchange rate for such Currency in
effect on the second Business Day prior to each payment date, or (y) with
respect to a Conversion Event, the applicable market exchange rate for such
Foreign Currency in effect (as nearly as feasible) at the time of the
Conversion Event.

                 The Company and the Guarantor shall pay and indemnify the
Trustee against any tax, fee or other charge, imposed on or assessed against
the Government Obligations deposited pursuant to this Section 402 or the
principal or interest received in respect thereof other than any such tax, fee
or other charge which by law is for the account of the Holders of such
Outstanding Securities and any Coupons appertaining thereto.

                 Anything in this Section 402 to the contrary notwithstanding,
the Trustee shall deliver or pay to the Company from time to time upon Company
Request, or the Guarantor, as the case may be, upon Guarantor's Request, any
money or Government Obligations (or other property and any proceeds therefrom)
held by it as provided in clause (4) of this Section 402 which, in the opinion
of a nationally recognized firm of independent public accountants expressed in
a written certification thereof delivered to the Trustee, are in excess of the
amount thereof which would then be required to be deposited to effect a
defeasance or covenant defeasance, as applicable, in accordance with this
Section 402.

                 Section 403.     Application of Trust Money.

                 Subject to the provisions of the last paragraph of Section
1003, all money and Government Obligations deposited with the Trustee pursuant
to Section 401 or 402 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 or
the Guarantor acting as its own Paying Agent) as the Trustee may determine, to
the Persons entitled thereto, of the principal, premium, interest and
Additional Amounts for whose payment such money has or Government Obligations
have been deposited with or received by the Trustee; but such money and
Government Obligations need not be segregated from other funds except to the
extent required by law.


                 Section 404.     Reinstatement.

   
                 If the Trustee or the Paying Agent is unable to apply any money
in accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture, such Securities and the related Guarantees from which the Company or
the Guarantor, as the case may be, has been discharged or released pursuant to
this Article shall be revived and reinstated as though no deposit has occurred
pursuant to this Article with respect to such Securities and the related
Guarantees, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to this Article with respect to such Securities
in accordance with this Article; provided, however, that if the Company or the
Guarantor makes any payment of principal of or any premium or interest on any
such Security or the related Guarantee following reinstatement of its
obligations, the Company or the Guarantor, as the case may be, shall be
subrogated to the rights (if any) of the Holders of such Securities to receive

                                  Annulment.

                 If an Event of Default with respect to Securities of any
series at the time Outstanding (other than an Event of Default specified in
clause (6) or (7) of Section 501) occurs and is continuing, then the Trustee or
the Holders of not less than 25% in principal amount of the Outstanding
Securities of such series may declare the principal of all the Securities of
such series, or such lesser amount as may be provided for in the Securities of
such series, to be due and payable immediately, by a notice in writing to the
Company and the Guarantor (and to the Trustee if given by the Holders), and
upon any such declaration such principal or such lesser amount shall become
immediately due and payable.





                                       48
<PAGE>   57
                 If an Event of Default specified in clause (6) or (7) of
Section 501 occurs, all unpaid principal of and accrued interest on the
Outstanding Securities of that series (or such lesser amount as may be provided
for in the Securities of such series) shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holder of any Security of that series.

                 At any time after Securities of any series have been
accelerated 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 not less than a majority in principal amount of the Outstanding
Securities of such series, by written notice to the Trustee, the Guarantor and
the Company, may rescind and annul such declaration and its consequences if

                 (1)      the Company or the Guarantor has paid or deposited 
with the Trustee a sum of money sufficient to pay

                 (a)      all overdue installments of any interest on and
         Additional Amounts with respect to all Securities of such series and
         any Coupon appertaining thereto,

                 (b)      the principal of and any premium on any Securities of
         such series which have become due otherwise than by such declaration
         of acceleration and interest thereon and any Additional Amounts with
         respect thereto at the rate or rates borne by or provided for in such
         Securities,

                 (c)      to the extent that payment of such interest or
         Additional Amounts is lawful, interest upon overdue installments of
         any interest and Additional Amounts at the rate or rates borne by or
         provided for in such Securities, 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 all other amounts due the
         Trustee under Section 606; and

                 (2)      all Events of Default with respect to Securities of
such series, other than the non-payment of the principal of, any premium and
interest on, and any Additional Amounts with respect to Securities of such
series which shall have become due solely by such declaration of acceleration,
shall have been cured or waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.


                 Section 503.     Collection of Indebtedness and Suits for
                                  Enforcement by Trustee.

                 The Company covenants, in each case, that if





                                       49
<PAGE>   58
                 (1)      there is a failure to pay any installment of interest
on or any Additional Amounts with respect to any Security or any Coupon
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)      there is a failure to pay the principal of or any
premium on any Security at its Maturity, the Company shall, upon demand of the
Trustee, pay to the Trustee, for the benefit of the Holders of such Securities
and any Coupons appertaining thereto, the whole amount of money then due and
payable with respect to such Securities and any Coupons appertaining thereto,
with interest upon the overdue principal, any premium and, to the extent that
payment of such interest shall be legally enforceable, upon any overdue
installments of interest and Additional Amounts at the rate or rates borne by or
provided for in such Securities, and, in addition thereto, such further amount
of money 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 and all other amounts due to the Trustee
under Section 606.

                 If the Company or the Guarantor fails to pay the money it is
required to pay the Trustee pursuant to the preceding paragraph forthwith upon
the demand of the Trustee, the Trustee, in its own name and as trustee of an
express trust, may institute a judicial proceeding for the collection of the
money so due and unpaid, and may prosecute such proceeding to judgment or final
decree, and may enforce the same against the Company or the Guarantor or any
other obligor upon such Securities and any Coupons appertaining thereto or the
Guarantees endorsed thereon and collect the monies adjudged or decreed to be
payable in the manner provided by law out of the property of the Company, the
Guarantor or any other obligor upon such Securities and any Coupons
appertaining thereto or the Guarantees endorsed thereon, 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 Coupons appertaining thereto 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 such Securities or in aid of the exercise of any power
granted herein or therein, or to enforce any other proper remedy.


                 Section 504.     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, the Guarantor or any
other obligor upon the Securities or the Guarantees endorsed thereon or the
property of the Company, the Guarantor or such other obligor or their
creditors, the Trustee (irrespective of whether the principal 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 or the Guarantor for the payment of any overdue principal, premium,
interest





                                       50

or Additional Amounts) shall be entitled and empowered, by intervention in such
proceeding or otherwise,

                 (1)      to file and prove a claim for the whole amount, or
         such lesser amount as may be provided for in the Securities of such
         series, of the principal and any premium, interest and Additional
         Amounts owing and unpaid in respect of the Securities and 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 or counsel) and
         of the Holders of Securities or any Coupons allowed in such judicial
         proceeding, and

                 (2)      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 of Securities or any Coupons 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 of Securities or any Coupons, to pay to the Trustee any
amount due to 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 606.

                 Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
of a Security or any Coupon any plan of reorganization, arrangement, adjustment
or composition affecting the Securities or Coupons or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any
Holder of a Security or any Coupon in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors'
committee or other similar committee.


                 Section 505.     Trustee May Enforce Claims without Possession
                                  of Securities, Guarantees or Coupons.

                 All rights of action and claims under this Indenture or any of
the Securities, the Guarantees or any Coupons may be prosecuted and enforced by
the Trustee without the possession of any of the Securities, Guarantees 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 or judgment, after provision for
the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, shall be for the ratable
benefit of each and every Holder of a Security or Coupon in respect of which
such judgment has been recovered.

                 Section 506.     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 any premium, interest or 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:

         predecessor Trustee under Section 606;

                 SECOND:  To the payment of the amounts then due and unpaid
         upon the Securities and any Coupons for principal and any premium,

         of which such money has been collected, ratably, without preference or
         priority of any kind, according to the aggregate amounts due and
         payable on such Securities and Coupons for principal and any premium,
         interest and Additional Amounts, respectively;

                 THIRD:  The balance, if any, to the Person or Persons entitled
         thereto.

                 Section 507.     Limitations on Suits.

                 No Holder of any Security of any series or any Coupons
appertaining thereto shall have any right to institute any proceeding, judicial
or otherwise, with respect to this Indenture, the Guarantees, the Securities of
any series or any Coupons appertaining thereto, or for the appointment of a
receiver or trustee, or for any other remedy hereunder, unless

                 (1)      such Holder has previously given written notice to
         the Trustee of a continuing Event of Default with respect to the
         Securities of such series;

                 (2)      the Holders of not less than 25% in principal amount
         of the Outstanding Securities of such 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;

                 (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





                                       52
<PAGE>   61
                 (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
         such 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 or any Security or Guarantee to affect, disturb or prejudice
the rights of any other such Holders or Holders of Securities of any other
series, or to obtain or to seek to obtain priority or preference over any other
Holders or to enforce any right under this Indenture, except in the manner
herein provided and for the equal and ratable benefit of all such Holders.

                 Section 508.     Unconditional Right of Holders to Receive
                                  Principal and any Premium, Interest and
                                  Additional Amounts.

                 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, any premium and (subject
to Sections 305 and 307) interest on, and any Additional Amounts with respect
to such Security or payment of such Coupon or payment pursuant to the Guarantee
endorsed on such Security, as the case may be, on the respective Stated
Maturity or Maturities therefor specified in such Security or Coupon (or, in
the case of redemption, on the Redemption Date or, in the case of repayment at
the option of such Holder if provided in or pursuant to this Indenture, on the
date such repayment is due, or in the case of a Change in Control, or as to any
Change in Control Purchase Notice given timely, on the Change in Control
Purchase Date) and to institute suit for the enforcement of any such payment,
and such right shall not be impaired without the consent of such Holder.


                 Section 509.     Restoration of Rights and Remedies.

                 If the Trustee or any Holder of a Security or a Coupon 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 the Company, the Guarantor, the Trustee and each such Holder shall,
subject to any determination in such proceeding, be restored severally and
respectively to their former positions hereunder, and thereafter all rights and
remedies of the Trustee and each such Holder shall continue as though no such
proceeding had been instituted.

                 Section 510.     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 each and every Holder of a Security or a Coupon
is intended to be exclusive of any other right or remedy, and every right and
remedy, to the extent permitted by law, shall be cumulative and in addition to
every other right and remedy given





                                       53
<PAGE>   62
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, to the extent permitted by law, prevent the concurrent assertion or
employment of any other appropriate right or remedy.


                 Section 511.     Delay or Omission not Waiver.

                 No delay or omission of the Trustee or of any Holder of any
Security or Coupon 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 any Holder of a Security or a
Coupon may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by such Holder, as the case may be.


                 Section 512.     Control by Holders of Securities.

                 Subject to Section 601(e), the Holders of a majority in
principal amount of the Outstanding Securities of any 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 with respect to the Securities of such series and any Coupons
appertaining thereto, provided that

                 (1)      such direction shall not be in conflict with any rule
         of law or with this Indenture or with the Securities of any series,

                 (2)      the Trustee may take any other action deemed proper
         by the Trustee which is not inconsistent with such direction, and

                 (3)      such direction is not unduly prejudicial to the
         rights of the other Holders of Securities of such series not joining
         in such action.


                 Section 513.     Waiver of Past Defaults.

                 The Holders of not less than a majority in principal amount of
the Outstanding Securities of any series on behalf of the Holders of all the
Securities of such series and any Coupons appertaining thereto may waive any
past or prospective default hereunder with respect to such series and its
consequences, except a default

                 (1)      in the payment of the principal of, any premium or
         interest on, or any Additional Amounts with respect to, any Security
         of such series or any Coupons appertaining thereto, or





                                       54
<PAGE>   63
                 (2)      in respect of a covenant or provision hereof which
         under Article Nine cannot be modified or amended without the consent
         of the Holder of each Outstanding Security of such series 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 514.     Waiver of Stay or Extension Laws.

                 Each of the Company and the Guarantor covenants that (to the
extent that it may lawfully do so) 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
each of the Company and the Guarantor expressly waives (to the extent that it
may lawfully do so) all benefit or advantage of any such law and covenants that
it will not hinder, delay or impede the execution of any power herein granted
to the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.

         any default (as defined in Section 602) or Event of Default with
         respect to the Securities of any series for which it is acting as
         Trustee unless either (1) a Responsible Officer of the Trustee

                 Within 90 days after the occurrence of any default hereunder
with respect to the Securities of any series, the Trustee shall transmit by
mail to all Holders of Securities of such series entitled to receive reports

committee or a trust committee of directors and/or Responsible Officers of the
Trustee in good faith determine that the withholding of such notice is in the
best interest of the Holders of Securities and Coupons of such series.  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.

                                  or Issuance of Securities.

                 The recitals contained herein and in the Securities, except the
Trustee's certificate of authentication, and in any Coupons shall be taken as
the statements of the Company and the Guarantor, and neither the Trustee nor any
Authenticating Agent assumes any responsibility for their correctness.  The
Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities or the Coupons appertaining thereto or the
Guarantees, except that the Trustee represents that it is duly authorized to
execute and deliver this Indenture, authenticate the Securities and perform its
obligations hereunder and that the statements made by it in a Statement of
Eligibility and Qualification on Form T-1 supplied to the Company are true and
accurate, subject to the qualifications set forth therein. Neither the Trustee
nor any Authenticating Agent shall be accountable for the use or application by
the Company of the Securities or the proceeds thereof.

Company or the Guarantor, in its individual or any other capacity, may become
the owner or pledgee of Securities or Coupons and, subject to Sections 310(b)
and 311 of the Trust Indenture Act, may otherwise deal with the Company and the
Guarantor with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Security Registrar or such other Person.

                 Section 605.     Money Held in Trust.

                 Except as provided in Section 403 and Section 1003, money held
by the Trustee in trust hereunder need not be segregated from other funds
except to the extent required by law and shall be held uninvested.  The Trustee
shall be under no liability for interest on any money received by it hereunder
except as otherwise agreed in writing with the Company or the Guarantor, as the
case may be.


                 Section 606.     Compensation and Reimbursement.

                 agrees:

                 (a)      to pay to the Trustee from time to time reasonable
         compensation for all services rendered by the Trustee hereunder (which
         compensation shall not be limited by any provision of law in regard to
         the compensation of a trustee of an express trust);

                 (b)      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





                                       58
<PAGE>   67
         Trustee in accordance with any provision of this Indenture (including
         the reasonable compensation and the expenses and disbursements of its
         agents and counsel), except any such expense, disbursement or advance
         as may be attributable to the Trustee's negligence or bad faith; and

                 (c)      to indemnify the Trustee and its agents for, and to
         hold them harmless against, any loss, liability or expense incurred
         without negligence or bad faith on their 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
         themselves against any claim or liability in connection with the
         exercise or performance of any of their 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 of any series upon all property and funds held or collected by the
Trustee as such, except funds held in trust for the payment of principal of,
and premium or interest on or any Additional Amounts with respect to particular
Securities or any Coupons appertaining thereto.

                 Any compensation or expense incurred by the Trustee after a
default specified by Section 501 is intended to constitute an expense of
administration under any then applicable bankruptcy or insolvency law.
"Trustee" for purposes of this Section 606 shall include any predecessor
Trustee but the negligence or bad faith of any Trustee shall not affect the
rights of any other Trustee under this Section 606.

                 The Company's obligations under this Section 606 and any lien
hereunder shall survive the resignation or removal of any Trustee, the
discharge of the Company's obligations pursuant to Article Four of this
Indenture and the termination of this Indenture.

                 Section 607.     Corporate Trustee Required; Eligibility.

Corporation, organized and doing business under the laws of the United States
of America, any state thereof or the District of Columbia, eligible under
Section 310(a)(1) of the Trust Indenture Act to act as trustee under an
indenture qualified under the Trust Indenture Act and that has a combined
capital and surplus (computed in accordance with Section 310(a)(2) of the Trust
Indenture Act) of at least $50,000,000 subject to supervision or examination by
Federal or state authority.  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 608.     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 pursuant
to Section 609.

                 (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 and the Guarantor.  If the instrument of acceptance by a successor
Trustee required by Section 609 shall not have been delivered to the 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 the Company and the Guarantor.

                 (d)      If at any time:

                 (i)      the Trustee shall fail to comply with the obligations
         imposed upon it under Section 310(b) of the Trust Indenture Act with
         respect to Securities of any series after written request therefor by
         the Company, the Guarantor or any Holder of a Security of such series
         who has been a bona fide Holder of a Security of such series for at
         least six months, or

                 (ii)     the Trustee shall cease to be eligible under Section
         607 and shall fail to resign after written request therefor by the
         Company, the Guarantor or any such Holder, or

                 (iii)    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, (A) the Company, by or pursuant to a Board Resolution,
may remove the Trustee with respect to all Securities or the Securities of such
series, or (B) subject to Section 315(e) of the Trust Indenture Act, any
Holder of a Security 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
removal of the Trustee with respect to all Securities of such series and the
appointment of a successor Trustee or Trustees.

                 (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 or pursuant to 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





                                       60
<PAGE>   69
particular series) and shall comply with the applicable requirements of Section
609.  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 609, 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 of Securities and accepted appointment in the manner
required by Section 609, any Holder of a Security 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 the Holders of Registered Securities, if any, of such series as
their names and addresses appear in the Security Register and, if Securities of
such series are issued as Bearer Securities, by publishing notice of such event
once in an Authorized Newspaper in each Place of Payment located outside the
United States.  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 Office.

                 Section 609.     Acceptance of Appointment by Successor.

                 (a)      Upon the appointment hereunder of any successor
Trustee with respect to all Securities, such successor Trustee so appointed
shall execute, acknowledge and deliver to the Company, the Guarantor and 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 hereunder of the retiring
Trustee; but, on the request of the Company, the Guarantor or such successor
Trustee, such retiring Trustee, upon payment of its charges, shall execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee and, subject to Section 1003, shall
duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder, subject nevertheless to its
claim, if any, provided for in Section 606.

                 (b)      Upon the appointment hereunder of any successor
Trustee with respect to the Securities of one or more (but not all) series, the
Company, the Guarantor, the retiring Trustee and such successor Trustee 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, such successor Trustee all the





                                       61
<PAGE>   70
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, 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 that no Trustee shall be responsible
for any notice given to, or received by, or any act or failure to act on the
part of any other Trustee hereunder, 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, such retiring Trustee
shall have no further responsibility for the exercise of rights and powers or
for the performance of the duties and obligations vested in the Trustee under
this Indenture with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates other than as hereinafter
expressly set forth, 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 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, the Guarantor, or such successor Trustee, such retiring
Trustee, upon payment of its charges with respect to the Securities of that or
those series to which the appointment of such successor relates and subject to
Section 1003 shall duly assign, transfer and deliver to such successor Trustee,
to the extent contemplated by such supplemental indenture, the 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, subject to its claim, if any, provided for in Section 606.

                 (c)      Upon request of any Person appointed hereunder as a
successor Trustee, the Company and the Guarantor 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 Person shall accept its appointment hereunder as a
successor Trustee unless at the time of such acceptance such successor Person
shall be qualified and eligible under this Article.


                 Section 610.     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 of the
corporate trust business of the Trustee, shall be the successor of the Trustee
hereunder, without the





                                       62
<PAGE>   71
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 611.     Appointment of Authenticating Agent.

                 The Trustee may appoint one or more Authenticating Agents
acceptable to the Company with respect to one or more series of Securities
which shall be authorized to act on behalf of the Trustee to authenticate
Securities of that or those series issued upon original issue, exchange,
registration of transfer, partial redemption or partial repayment 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 the Guarantor and, except as provided in or pursuant to this Indenture,
shall at all times be a corporation that would be permitted by the Trust
Indenture Act to act as trustee under an indenture qualified under the Trust
Indenture Act, is authorized under applicable law and by its charter to act as
an Authenticating Agent and has a combined capital and surplus (computed in
accordance with Section 310(a)(2) of the Trust Indenture Act) of at least
$50,000,000.  If at any time an Authenticating Agent shall cease to be eligible
in accordance with the provisions of this Section, it 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
Authenticating Agent shall be a party, or any Corporation succeeding to all or
substantially all of the corporate agency or corporate trust business of an
Authenticating Agent, shall be the successor of such Authenticating Agent
hereunder, 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, the Company and the Guarantor.  The
Trustee may at any time terminate the agency of an Authenticating Agent by
giving written notice thereof to such Authenticating Agent, the Company and the

the Company and shall (i) mail written notice of such appointment by
first-class mail, postage prepaid, to all Holders of Registered Securities, if
any, of the series with respect to which such Authenticating Agent shall serve,
as their names and addresses appear in the Security Register, and (ii) if
Securities of the series are issued as Bearer Securities, publish notice of
such appointment at least once in an Authorized Newspaper in the place where
such successor Authenticating Agent has its principal office if such office is
located outside the United States.  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.

to time reasonable compensation for its services under this Section.  If the
Trustee makes such payments, it shall be entitled to be reimbursed for such
payments, subject to the provisions of Section 606.

                 The provisions of Sections 308, 603 and 604 shall be
applicable to each Authenticating Agent.

more series of Securities pursuant to this Section, the Securities of such
series may have endorsed thereon, in addition to or in lieu of the Trustee's
certificate of authentication, an alternate certificate of authentication in
substantially the following form:

                 This is one of the Securities of the series designated herein
         referred to in the within-mentioned Indenture.

Company is merged or to whom the Company has conveyed, transferred or leased
its properties and assets as an entirety or substantially as an entirety (a

supplemental hereto, executed and delivered to the Trustee, in form
satisfactory to the Trustee, (i) to immediately indemnify (pursuant to the

or required to be withheld or deducted from any payment to such Holder
(including any governmental charge or withholding attributable to such Person's
indemnifying such Holder) as a consequence of such consolidation, merger,
conveyance, transfer or lease, and (B) any other tax costs or other tax
expenses of the act of such consolidation, merger, conveyance, transfer or
lease (except that if the Company or any such Person delivers by the date of
any such transaction an opinion of an independent counsel or a tax consultant
of recognized standing that the Holders will not recognize income, gain or loss
for U.S. federal income tax purposes as a result of such transaction, a Holder
will have such rights to indemnification only if and when gain for U.S. federal
income tax purposes is actually imposed on such Holders) and (ii) that all
payments pursuant to the Securities in respect of the principal of and any
premium and interest on such Securities, as the case may be, shall be made
without withholding or deduction for, or on account of, any present or future
taxes, duties, assessments or governmental charges of whatever nature imposed
or levied by or on behalf of the jurisdiction of organization of such Person or
any political subdivision or taxing authority thereof or therein, unless such
taxes, duties, assessments or governmental charges are required by such
jurisdiction or any such subdivision or authority to be withheld or deducted,
in which case such Person will pay by way of additional interest such
additional amounts of or in respect of, principal and any premium and interest
("Successor Additional Amounts") as will result (after deduction of such taxes,
duties, assessments or governmental charges and any additional taxes, duties,
assessments or governmental charges payable in respect of such) in the payment

pursuant to the Securities had no such withholding or deduction been required,
except that no Successor Additional Amounts shall be so payable for or on
account of:

                                  (A) any tax, duty, levy, assessment or other
         governmental charge which would not have been imposed but for the fact
         that such Holder: (i) was a resident, domiciliary or national of, or
         engaged in business or maintained a

         of organization of such Successor or any of its territories or any
         political subdivision thereof or otherwise had some connection with
         such jurisdiction other than the mere ownership of, or receipt of
         payment under, such Security; (ii) presented (if presentation is

         (30) days after the date on which the payment in respect of such
         Security first became due and payable or provided for, whichever is
         later, except to the extent that the Holder would have been entitled
         to such Successor Additional Amounts if it had presented such Security
         for payment on any day within such period of thirty (30) days;

                                  (B) any estate, inheritance, gift, sale,
         transfer, personal property or similar tax, assessment or other
         governmental charge;

                                  (C) any tax, assessment or other governmental
         charge which is payable otherwise than by withholding or deduction from
         payments of (or in respect of) principal of or any premium or interest
         on, such Securities;

                                  (D) any tax, assessment or other governmental
         charge that is imposed or withheld by reason of the failure to comply
         by the Holder or the beneficial owner of the Security with a request of
         the Company or the Successor addressed to the Holder (i) to provide
         information concerning the nationality, residence or identity of the
         Holder or such beneficial owner or (ii) to make any declaration or
         other similar claim or satisfy any information or reporting
         requirement, which, in the case of (i) or (ii), is required or imposed
         by statute, treaty, regulation or administrative practice of the taxing
         jurisdiction as a precondition or exemption from all or part of such
         tax, assessment or other governmental charge; or

                                  (E) any combination of items (A), (B), (C)
         and (D);

nor shall Successor Additional Amounts be paid with respect to any payment of
the principal of or any premium or interest on any such Security to any Holder
who is a fiduciary or partnership or other than the sole beneficial owner of
such payment to the extent such payment would be required by the laws of the
jurisdiction of organization of such Person (or any political subdivision or
taxing authority thereof or therein) to be included in the income for tax
purposes of a beneficiary or settlor with respect to such fiduciary or a member
of such partnership or a beneficial owner who would not have been entitled to
such Successor Additional Amounts had it been the Holder of the Security; and

                 (4) such Subsidiary Issuer has delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel, each stating that such
consolidation, merger, conveyance, transfer or lease and,





                                       69
<PAGE>   78
if a supplemental indenture is required in connection with such transaction,
such supplemental indenture comply with this Article and that all conditions
precedent herein provided for relating to such transaction have been complied
with.

         (b)      The Company may assign its obligations under any series of
Securities to any other Subsidiary (the "Subsidiary Assignee") and such
Subsidiary Assignee shall be treated as the Successor to the Company with
respect to such series of Securities, provided that the conditions set forth 
in Section 802(a) that would apply to the merger of the Company into such
Subsidiary Assignee are satisfied.

                                  or Guarantor.
                 Upon any consolidation by the Company or the Guarantor with or
merger of the Company or the Guarantor into any other Person or any conveyance,
transfer or lease of the properties and assets of the Company or the Guarantor,
as the case may be, as an entirety or substantially as an entirety to any
Person in accordance with Sections 801 or 802, the successor Person formed by
such consolidation or into which the Company or the Guarantor, as the case may
be, is merged or to which such conveyance, transfer or lease is made shall
succeed to, and be substituted for, and may exercise every right and power of,
the Company or the Guarantor, as the case may be, under this Indenture with the
same effect as if such successor Person had been named as the Company or the
Guarantor, as the case may be, herein; and thereafter, except in the case of a
lease, the predecessor Person shall be released from all obligations and
covenants under this Indenture, the Securities, the Guarantees and the Coupons.

                 Section 804.     Assumption by the Guarantor of the Company's
                                  Obligations
 
         (a) The Guarantor may, at its option, assume the obligations of the
Company as obligor under any series of Securities and this Indenture; provided
that:

                  (i)  the Guarantor expressly assumes in an assumption
agreement or supplemental indenture hereto, executed and delivered to the
Trustee, in form satisfactory to the Trustee, the due and punctual payment of
the principal of and any premium and interest on such Securities and the
performance or observance of every covenant of this Indenture on the part of
the Company to be performed or observed (including any obligation to pay any
Additional Amounts);

                   (ii) immediately after giving effect to such assumption, no
Event of Default and no event, which after notice or lapse of time or both,
would become an Event of Default, shall have occurred and be continuing; and

                  (iii) the Guarantor shall expressly agree in an assumption
agreement or supplemental indenture hereto, executed and delivered to the
Trustee, in form satisfactory to the Trustee, to





                                       70
<PAGE>   79
immediately indemnify (pursuant to the indemnification procedure described in
Section 805) the Holder of each Security against (i) any tax, assessment or
governmental charge imposed on such Holder or required to be withheld or
deducted from any payment to such Holder (including any governmental charge or
withholding tax attributable to the Guarantor indemnifying such Holder) as a
consequence of such assumption and (ii) any costs or expenses of such
assumption (except that if the Guarantor delivers to the Trustee an opinion of
an independent counsel or a tax consultant of recognized standing that the
Holders will not recognize income, gain or loss for U.S. federal income tax
purposes as a result of such assumption by the date of such assumption, a
Holder will have indemnification rights pursuant to the indemnification
procedure described in Section 805 only if and when gain for U.S. federal
income tax purposes is actually imposed on such Holder); and

                 (iv) the Guarantor shall have delivered to the Trustee an
Officers' Certificate stating that such assumption and such assumption
agreement comply with this Article and that all conditions precedent herein
provided for relating to such assumption have been complied with.

         (b)  Upon any assumption pursuant to Section 804(a), the Guarantor
shall succeed to, and be substituted for, and may exercise every right and
power of, the Company under such Securities and this Indenture with the same
effect as if the Guarantor had been named as the Company herein, and  the
Company shall be released from its liability as obligor upon the Securities and
any Coupons and under this Indenture.


                 Section 805.     Indemnification Procedure
         (a) If a transaction described above under Sections 801, 802 or 804
(an "Indemnifiable Transaction") should constitute a taxable event for U.S.
federal income tax purposes, the Guarantor or any other Person that assumes the
obligations of the Guarantor or the Company pursuant to such Sections, as the
case may be, shall indemnify a Holder of a Security against any tax, assessment
or governmental charge imposed on such Holder or required to be withheld or
deducted from any payment to such Holder (including any governmental charge or
withholding attributable to an indemnification payment made by or on behalf of
the Guarantor or any such Person) and any other tax costs or other tax expenses
attributable to such Indemnifiable Transaction, and the Guarantor or any such
Person, as the case may be, shall comply with the following indemnification
procedures:

                 (1)  Unless the Guarantor or any such Person, as the case may
be, delivers to the Trustee by the date of an Indemnifiable Transaction an
opinion of an independent counsel or a tax consultant of recognized standing to
the effect that such Indemnifiable Transaction will not be a  taxable event for
U.S. federal income tax purposes, the Guarantor or any such Person, as the case
may be, shall send to each Holder on or prior to the date of such Indemnifiable
Transaction (i) notification explaining the U.S. federal income tax
consequences to each such Holder of such Indemnifiable Transaction and (ii) an
indemnification claim form requesting (A)information concerning each such
Holder's tax basis and holding period in a Security and (B) a statement that
the Holder is not then an





                                       71
<PAGE>   80
entity described in Section 501 of the Code that is exempt from U.S. federal
income tax and (iii) a statement setting forth the address to which each such
Holder must remit such form.

                 (2) If the Guarantor or any such Person delivers such an
opinion, each Holder will have indemnification rights pursuant to this Section
805 only if and when gain for U.S. federal income tax purposes is actually
imposed on such Holder.

                 (3) When the Guarantor or any such Person, as the case may be,
receives from a Holder an indemnification claim form, the Guarantor or such
Person, as the case may be, shall within 15 Business Days remit to such Holder
a certified check in an amount equal to the sum of (i) the product of any gain
recognized as a result of the Indemnifiable Transaction and the highest
marginal tax rate in effect at the time of such Indemnifiable Transaction (the
"Indemnification Amount"), and (ii) the product of the Indemnification Amount
and such tax rate. For these purposes, a Holder's gain shall equal the amount
by which the fair market value of a Security at the time of such Indemnifiable
Transaction exceeds such Holder's adjusted tax basis in such Security.

                 Section 902.     Supplemental Indentures with Consent of
                                  Holders.

                 With the consent of the Holders of not less than 66-2/3% in
principal amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company (when authorized by or pursuant to a Board Resolution),
the Guarantor (when authorized by or pursuant to a Board Resolution) and the
Trustee may enter into an indenture or indentures supplemental hereto for the
purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Indenture or of modifying in any manner the
rights of the Holders of Securities of such series under this Indenture or of
the Securities of such series; provided, however, that no such supplemental
indenture, without the consent of the Holder of each Outstanding Security
affected thereby, shall

                 (a)      change the Stated Maturity of the principal of, or
any premium or installment of interest on or any Additional Amounts with

Amounts pursuant to Section 1004 (except as contemplated by Section 801(a) and
permitted by Section 901(a)), or reduce the amount of the principal of an
Original Issue Discount Security that would be due and payable upon a
declaration of acceleration of the Maturity thereof pursuant to Section 502 or
the amount thereof provable in bankruptcy pursuant to Section 504, change the
redemption provisions or adversely affect the right of repayment at the option
of any Holder as contemplated by Article Twelve, or change the Place of
Payment, Currency in which the principal of, any premium or interest on, or any

to institute suit for the enforcement of any such payment on or after the
Stated Maturity thereof (or, in the case of redemption, on or after the
Redemption Date or, in the case of repayment at the option of the Holder, on or
after the date for repayment or in the case of change in control, after the
Change in Control Purchase Date), or

                 (b)      reduce the percentage in principal amount of the
Outstanding Securities of any series, the consent of whose Holders is required
for any such supplemental indenture, or the consent of whose Holders is
required for any waiver (of compliance with certain provisions of this
Indenture or certain defaults hereunder and their consequences) provided for in
this Indenture, or reduce the requirements of Section 1404 for quorum or
voting, or

                 (c)      modify or effect in any manner adverse to the Holders
the terms and conditions of the obligations of the Company under the Securities
or the Coupons, the Guarantor under the Guarantees, or either of them hereunder,
in respect of the due and punctual payments of principal of, any premium or
interest on, or any Additional Amounts with respect to, the Securities, or

                 (d)      modify any of the provisions of this Section, Section
513 or Section 1008, except to increase any such percentage or to provide that
certain other provisions of this Indenture





                                       74
<PAGE>   83
cannot be modified or waived without the consent of the Holder of each
Outstanding Security affected thereby.

                 A supplemental indenture which changes or eliminates any
covenant or other provision of this Indenture which shall have been included
expressly and solely for the benefit of one or more particular series of
Securities, or which modifies the rights of the Holders of Securities of such
series with respect to such covenant or other provision, shall be deemed not to
affect the rights under this Indenture of the Holders of Securities of any
other series.

                 It shall not be necessary for any Act of Holders of Securities
under this Section to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such Act shall approve the substance
thereof.

                 Section 903.     Execution of Supplemental Indentures.

                 As a condition to executing, or accepting the additional
trusts created by, any supplemental indenture permitted by this Article or the
modifications thereby of the trust created by this Indenture, the Trustee shall
be entitled to receive (in addition to those documents required by Section
102), and (subject to Section 315 of the Trust Indenture Act) shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture.  The
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise.

                 Section 904.     Effect of Supplemental Indentures.

                 Upon the execution of any supplemental indenture under this
Article, this Indenture shall be modified in accordance therewith, and such
supplemental indenture shall form a part of this Indenture for all purposes;
and every Holder of a Security theretofore or thereafter authenticated and
delivered hereunder and of any Coupon appertaining thereto shall be bound
thereby.


                 Section 905.     Reference in Securities to Supplemental
                                  Indentures.

                 Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture.  If the Company and
the Guarantor shall so determine, new Securities of any series so modified as
to conform, in the opinion of the Trustee and the Company, to any such
supplemental indenture may be prepared with Guarantees endorsed thereon, if
appropriate, and executed by the





                                       75

<PAGE>   84
Company and authenticated and delivered by the Trustee in exchange for
Outstanding Securities of such series.

                 Section 906.     Conformity with Trust Indenture Act.

                 Every supplemental indenture executed pursuant to this Article
shall conform to the requirements of the Trust Indenture Act as then in effect.



                                  ARTICLE TEN

                                   COVENANTS


                 Section 1001.    Payment of Principal, any Premium, Interest
                                  and Additional Amounts.

                 The Company covenants and agrees for the benefit of the
Holders of the Securities of each series that it will duly and punctually pay
the principal of, any premium and interest on and any Additional Amounts with
respect to the Securities of such series in accordance with the terms thereof,
any Coupons appertaining thereto and this Indenture.  Any interest due on any
Bearer Security on or before the Maturity thereof, and any Additional Amounts
payable with respect to such interest, shall be payable only upon presentation
and surrender of the Coupons appertaining thereto for such interest as they
severally mature.

                 Section 1002.    Maintenance of Office or Agency.

                 The Company and the Guarantor shall maintain in each Place of
Payment for any series of Securities an Office or Agency where Securities of
such series, and Guarantees with respect thereto (but not Bearer Securities,
except as otherwise provided below, unless such Place of Payment is located
outside the United States), may be presented or surrendered for payment, where
Securities of such series may be surrendered for registration of transfer or
exchange, and where notices and demands to or upon the Company and the
Guarantor in respect of the Securities of such series relating thereto and this
Indenture may be served.  If Securities of a series are issuable as Bearer
Securities, the Company and the Guarantor shall maintain, subject to any laws
or regulations applicable thereto, an Office or Agency in a Place of Payment
for such series which is located outside the United States where Securities of
such series and any Coupons appertaining thereto, and Guarantees with respect
thereto, may be presented and surrendered for payment; provided, however, that
if the Securities of such series are listed on The Stock Exchange of the United
Kingdom and the Republic of Ireland or the Luxembourg Stock Exchange or any
other stock exchange located outside the United States and such stock exchange
shall so require, the Company and the Guarantor shall maintain a Paying Agent





                                       76
<PAGE>   85
in London, Luxembourg or any other required city located outside the United
States, as the case may be, so long as the Securities of such series are listed
on such exchange.  The Company and the Guarantor 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 and the Guarantor 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 Office of the Trustee,
except that Bearer Securities of such series and any Coupons appertaining
thereto, and Guarantees with respect thereto, may be presented and surrendered
for payment at the place specified for the purpose with respect to such
Securities as provided in or pursuant to this Indenture, and the Company and
the Guarantor hereby appoint the Trustee as their agent to receive all such
presentations, surrenders, notices and demands.

                 Except as otherwise provided in or pursuant to this Indenture,
no payment of principal, premium, interest or Additional Amounts with respect
to Bearer Securities shall be made at any Office or Agency 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; provided, however,
if amounts owing with respect to any Bearer Securities shall be payable in
Dollars, payment of principal of, any premium or interest on and any Additional
Amounts with respect to any such Security, or the Guarantees with respect
thereto, may be made at the Corporate Trust Office of the Trustee or any Office
or Agency designated by the Company in the Borough of Manhattan, The City of
New York, if (but only if) payment of the full amount of such principal,
premium, interest or Additional Amounts at all offices outside the United
States maintained for such purpose by the Company and the Guarantor in
accordance with this Indenture is illegal or effectively precluded by exchange
controls or other similar restrictions.

                 The Company and the Guarantor may also from time to time
designate one or more other Offices or Agencies where the Securities of one or
more series, and the Guarantees endorsed thereon, 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 or the Guarantor of its obligation to
maintain an Office or Agency in each Place of Payment for Securities of any
series for such purposes.  The Company and the Guarantor shall 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.  Unless otherwise
provided in or pursuant to this Indenture, the Company and the Guarantor hereby
designate as the Place of Payment for each series of Securities and the
Guarantees endorsed thereon, the Borough of Manhattan, The City of New York,
and initially appoints the Corporate Trust Office of the Trustee as the
Company's or the Guarantor's  Office or Agency in the Borough of Manhattan, The
City of New York for such purpose.  The Company and the Guarantor may
subsequently appoint a different Office or Agency in the Borough of Manhattan,
The City of New York for the Securities of any series, and the Guarantees
endorsed thereon.

                 Unless otherwise specified with respect to any Securities
pursuant to Section 301, if and so long as the Securities of any series (i) are
denominated in a Foreign Currency or (ii) may be





                                       77
<PAGE>   86
payable in a Foreign Currency, or so long as it is required under any other
provision of this Indenture, then the Company and the Guarantor will maintain
with respect to each such series of Securities, or as so required, at least one
exchange rate agent.

                 Section 1003.    Money for Securities Payments to Be Held in
                                  Trust.

                 If the Company or the Guarantor, as the case may be, shall at
any time act as its own Paying Agent with respect to any series of Securities,
it shall, on or before each due date of the principal of, any premium or
interest on or Additional Amounts with respect to any of the Securities of such
series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum in the Currency or Currencies in which the Securities of such
series are payable (except as otherwise specified pursuant to Section 301 for
the Securities of such series) sufficient to pay the principal or any premium,
interest or Additional Amounts so becoming due until such sums shall be paid to
such Persons or otherwise disposed of as herein provided, and shall promptly
notify the Trustee of its action or failure so to act.

                 Whenever the Company or the Guarantor, as the case may be,
shall have one or more Paying Agents for any series of Securities, it shall, on
or prior to each due date of the principal of, any premium or interest on or
any Additional Amounts with respect to any Securities of such series, deposit
with any Paying Agent a sum (in the Currency or Currencies described in the
preceding paragraph) sufficient to pay the principal or any premium, interest
or Additional Amounts so becoming due, such sum to be held in trust for the
benefit of the Persons entitled thereto, and (unless such Paying Agent is the
Trustee) the Company or the Guarantor, as the case may be, will promptly notify
the Trustee of its action or failure so to act.

                  The Company shall 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 shall:

                 (a)      hold all sums held by it for the payment of the
principal of, any premium or interest on or any Additional Amounts with respect
to Securities of such 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 provided in or pursuant to this Indenture;

                 (b)      give the Trustee notice of any default by the Company
or the Guarantor (or any other obligor upon the Securities of such series) in
the making of any payment of principal, any premium or interest on or any
Additional Amounts with respect to the Securities of such series; and

                 (c)      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 or the Guarantor, as the case may be, may at any
time, for the purpose of obtaining the satisfaction and discharge of this
Indenture or for any other purpose, pay, or by





                                       78
<PAGE>   87
Company Order of the Company or the Guarantor direct any Paying Agent to pay,
to the Trustee all sums held in trust by the Company, the Guarantor or such
Paying Agent, such sums to be held by the Trustee upon the same terms as those
upon which such sums were held by the Company, the Guarantor 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 sums.

                 Except as otherwise provided herein or pursuant hereto, any
money deposited with the Trustee or any Paying Agent, or then held by the
Company or the Guarantor, as the case may be, in trust for the payment of the
principal of, any premium or interest on or any Additional Amounts with respect
to any Security of any series or any Coupon appertaining thereto and remaining
unclaimed for two years after such principal or any such premium or interest or
any such Additional Amounts shall have become due and payable shall be paid to
the Company or the Guarantor, as the case may be, on Company Request, or (if
then held by the Company or the Guarantor) shall be discharged from such trust;
and the Holder of such Security or any Coupon appertaining thereto, or
Guarantees endorsed thereon, shall thereafter, as an unsecured general
creditor, look only to the Company or the Guarantor (pursuant to the
Guarantees) 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
or the Guarantor (pursuant to Guarantee) 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 each Place of Payment for such
series or to be mailed to Holders of Registered Securities of such series, or
both, notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication
or mailing nor shall it be later than two years after such principal and any
premium or interest or Additional Amounts shall have become due and payable,
any unclaimed balance of such money then remaining will be repaid to the
Company or the Guarantor, as the case may be.


                 Section 1004.    Additional Amounts.

                 If any Securities of a series provide for the payment of
Additional Amounts, the Company and the Guarantor each agrees to pay to the
Holder of any such Security or any Coupon appertaining thereto Additional
Amounts as provided in or pursuant to this Indenture or such Securities.
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 any 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 by the terms of such
series established hereby or pursuant hereto to the extent that, in such
context, Additional Amounts are, were or would be payable in respect thereof
pursuant to such terms, and express mention of the payment of Additional
Amounts (if applicable) in any provision hereof shall not be construed as
excluding Additional Amounts in those provisions hereof where such express
mention is not made.





                                       79
<PAGE>   88
                 Except as otherwise provided in or pursuant to this Indenture
or the Securities of the applicable series, 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 such series of Securities (or if the
Securities of such series shall not bear interest prior to Maturity, the first
day on which a payment of principal is made), and at least 10 days prior to each
date of payment of principal or interest if there has been any change with
respect to the matters set forth in the below mentioned Officers' Certificate,
the Company or the Guarantor, as the case may be, shall furnish to the Trustee
and the principal Paying Agent or Paying Agents, if other than the Trustee, an
Officers' Certificate instructing the Trustee and such Paying Agent or Paying
Agents whether such payment of principal of and premium, if any, or interest on
the Securities of such series shall be made to Holders of Securities of such
series or the Coupons appertaining thereto who are United States Aliens without
withholding for or on account of any tax, assessment or other governmental
charge described in the Securities of such 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 agrees to pay to the Trustee or such
Paying Agent the Additional Amounts required by the terms of such Securities.
Each of the Company and the Guarantor, jointly and severally, 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.

                 Section 1005.    Limitation on Liens.

                 Nothing in this Indenture or in the Securities shall in any
way restrict or prevent the Company, the Guarantor or any other Subsidiary from
issuing, assuming, guaranteeing or otherwise incurring any indebtedness;
provided, however, that neither the Company, the Guarantor nor any other
Subsidiary shall issue, assume or guaranty any notes, bonds, debentures or
other similar evidences of indebtedness for money borrowed secured by any Lien
on any asset now owned or hereafter acquired by it without making effective
provision whereby any and all Securities then or thereafter outstanding shall
be secured by a Lien equally and ratably with any and all other obligations
thereby secured, so long as any such obligations shall be so secured.
Notwithstanding the foregoing, the Company, the Guarantor or any other
Subsidiary, without so securing the Securities, may issue, assume or guaranty
indebtedness secured by the following Liens:

                 (a)  Liens existing on the date of this Indenture or provided
         for under the terms of agreements existing on the date hereof;

         cost of exploration, production, gathering, processing, marketing,
         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 in
         connection with such property,





                                       80
<PAGE>   89
         and (iii) indebtedness incurred by the Guarantor, the Company or any
         other Subsidiary to provide funds for the activities set forth in
         clauses (i) and (ii) above;

                 (c)  Liens which secure indebtedness owing by a Subsidiary to
         the Guarantor or to one or more other Subsidiaries, or to the
         Guarantor and one or more other Subsidiaries;

                 (d)  Liens on the property of any Person existing at the time
         such Person becomes a Subsidiary;

                 (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, (ii) indebtedness issued or guaranteed by the
         United States, any state or any department, agency or instrumentality
         of either or (iii) indebtedness issued or guaranteed by (Y) a foreign
         government, any state or any department, agency or instrumentality of
         either or (Z) an international finance agency or any division or
         department thereof, including the World Bank, the International
         Finance Corp. and the Multilateral Investment Guarantee Agency;

                 (f)  any Lien extending, renewing or replacing (or
         successive extensions, renewals or replacements of) any Lien of the
         type set forth in paragraphs (a) through (e) above, which Lien exists
         on the date of this Indenture;

                 (g)  any Ordinary Course Lien (as defined below) arising,
         and only so long as continuing, in the ordinary course of the business
         of the Guarantor; or

                 (h)  Liens which secure Limited Recourse Indebtedness.

                 Notwithstanding the foregoing, the Guarantor and any one or
more other Subsidiaries may issue, assume or guaranty the following
indebtedness secured by Liens on assets without regard to the foregoing
limitations: indebtedness in any aggregate principal amount which, together
with the aggregate outstanding principal amount of all other indebtedness of
the Company, the Guarantor and its other Subsidiaries so secured (excluding
indebtedness secured by the permitted Liens described above), and the aggregate
amount of Sale/Leaseback Transaction obligations which would otherwise be
subject to the provisions of Section 1006, does not at the time such
indebtedness is incurred exceed 10% of the Guarantor's Consolidated Net Worth
as shown on the most recent audited consolidated balance sheet of the Guarantor
and its Subsidiaries.

                 Notwithstanding the foregoing, nothing in this Section 1005
shall be deemed to prohibit or otherwise limit the following types of
transactions:

                 (1)(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





                                       81
<PAGE>   90
         or such crude oil, natural gas or other petroleum hydrocarbons, or
         (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 sales or similar interest; and

                 (2) the granting of Liens required by any contract or statute
         in order to permit the Guarantor or a Subsidiary to perform any
         contract or subcontract made by it with or at the request of the
         United States government or any foreign government or international
         finance agency, any state or any department thereof, or any agency or
         instrumentality thereof, or to secure partial, progress, advance or
         other payments to the Guarantor or any other Subsidiary by any such
         entity pursuant to the provisions of any contract or statute.

                 "Lien" shall mean, with respect to any asset, any mortgage,
lien, pledge, security interest or encumbrances of any kind in respect of such
asset, whether or not filed, recorded or otherwise perfected under applicable
law.  The Company, the Guarantor or any other Subsidiary shall be deemed to own
subject to a Lien any asset which it has acquired or holds subject to the
interest of a vendor or lessor under any conditional sale agreement, capital
lease or other title retention agreement relating to such asset.  The right of
set-off, whether by operation of law or by contract, does not constitute a Lien
unless there is a related obligation to maintain a deposit of cash or other
assets in respect of which such right of set-off may be exercised.

                 "Ordinary Course Lien" shall mean:

                 (a)      Liens for taxes, assessments or governmental changes
         or levies on the property of the Company, the Guarantor or any other
         Subsidiary if the same shall not at the time be delinquent or
         thereafter can be paid without penalty, or are being contested in good
         faith and by appropriate proceedings and for which adequate reserves
         in accordance with generally accepted accounting principles shall have
         been set aside on the books of the Company or the Guarantor;

                 (b)      Liens imposed by law, such as carriers',
         warehousemen's, landlords' and mechanics' liens and other similar
         liens arising in the ordinary course of business which secure
         obligations not more than 60 days past due or which are being
         contested in good faith by appropriate proceedings and for which
         adequate reserves in accordance with generally accepted accounting
         principles shall have been set aside on the books of the Company or
         the Guarantor;

                 (c)      Liens arising out of pledges or deposits under
         worker's compensation laws, unemployment insurance, old age pensions,
         or other social security or retirement benefits, or similar
         legislation;

                 (d)      Utility easements, building restrictions and such
         other encumbrances or charges against real property as are of a nature
         generally existing with respect to properties of a similar character
         and which do not in any material way affect the marketability of the





                                       82

         same or interfere with the use thereof in the business of the Company,
         the Guarantor or its other Subsidiaries, as the case may be;

                 (e)      Liens arising under operating agreements or similar
         agreements in respect of obligations which are not yet due or which
         are being contested in good faith by appropriate proceedings;

                 (f)      Liens reserved in oil, gas and/or mineral leases for
         bonus or rental payments and for compliance with the terms of such
         leases;

                 (g)      Liens pursuant to partnership agreements, oil, gas
         and/or mineral leases, farm-out-agreements, division orders, contracts
         for the sale, purchase, exchange, or processing of oil, gas and/or
         other hydrocarbons, unitization and pooling declarations and
         agreements, operating agreements, development agreements, area of
         mutual interest agreements, forward sale agreements, oil and gas
         delivery obligations, and other agreements which are customary in the
         oil, gas and other mineral exploration, development and production
         business and in the business of processing of gas and gas condensate
         production of the extraction of products therefrom;

                 (h)      Liens on personal property (excluding the capital
         stock or indebtedness of any Subsidiary) securing indebtedness
         maturing not more than one year from the date of its creation; and

                 (i)      Liens relating to a judgment or other court-ordered
         award or settlement as to which the Guarantor or the Company has not
         exhausted its appellate rights.

                 "Consolidated Net Worth" means the consolidated stockholders'
equity of the Guarantor, determined in accordance with generally accepted
accounting principles.


                 Section 1006.    Limitation on Sale/Leaseback Transactions.

                 None of the Company, the Guarantor or any other Subsidiary
will enter into any Sale/Leaseback Transaction with any Person (other than the
Guarantor or a Subsidiary) providing for a term of more than three years
unless:

                 (a) the Company, the Guarantor or such other Subsidiary would
         be permitted, pursuant to the terms of Section 1005, to incur
         indebtedness in an aggregate principal amount equal to or exceeding
         the value of the Sale/Leaseback Transaction secured by a Lien on the
         property subject to such Sale/Leaseback Transaction;

                 (b) since the date of this Indenture and within a period
         commencing six months prior to the Sale/Leaseback Transaction and
         ending six months after the consummation thereof,





                                       83
<PAGE>   92
         the Company, the Guarantor or such other Subsidiary expends for any
         property (including amounts expended for the acquisition, exploration,
         drilling or development thereof, or for additions, alterations,
         improvements or repairs thereto) an amount up to the net proceeds of
         such Sale/Leaseback Transaction, and the Company or the Guarantor, as
         the case may be, elects to designate such amount as a credit against
         such Sale/Leaseback Transaction (with any amount of such net proceeds
         not being so designated to be applied as set forth in paragraph (c)
         below); or

                 (c) the Company or Guarantor, as the case may be, during or
         immediately after the expiration of the 12 month period following the
         consummation of the Sale/Leaseback Transaction, applies to the
         voluntary retirement, redemption or defeasance of the Securities and
         its other Senior Indebtedness an amount equal to the greater of (i) the
         net proceeds of the Sale/Leaseback Transaction and (ii) the fair value,
         in the opinion of the Board of Directors of the Company or the
         Guarantor, as the case may be, of the subject property of the
         Sale/Leaseback Transaction at the time of such transaction (adjusted,
         in either case, to reflect the remaining term of the lease and any
         amount applied pursuant to paragraph (b) above), less an amount equal
         to the principal amount of other Senior Indebtedness voluntarily
         retired by the Company or the Guarantor, as the case may be, during
         such 12-month period.

         "Sale/Leaseback Transaction" means any arrangement providing for the
leasing to the Company, the Guarantor or any other Subsidiary by any Person
(other than the Guarantor, the Company or any other Subsidiary) of any property
which has been, or is to be, sold or transferred by the Guarantor, the Company
or such other Subsidiary to such Person or to any Person (other than the
Company or any other Subsidiary) to which funds have been or are to be advanced
by such Person on the security of the leased property, except with respect to
any lease that secures or relates to obligations issued by or on behalf of (a)
the United States, any state or any department, agency or instrumentality of
either, (b) a foreign government, any state or any department agency or
instrumentality of either, or (c) an international finance agency or any
division or department thereof, including the World Bank, the International
Finance Corp. and the Multilateral Investment Guarantee Agency, in connection
with the financing of the cost of construction, improvement or equipping of
such property.

                 Section 1007.    Corporate Existence.

                 Subject to Articles Eight and Fifteen, each of the Company and
the Guarantor shall do or cause to be done all things necessary to preserve and
keep in full force and effect its corporate existence and that of each other
Subsidiary and their respective rights (charter and statutory) and franchises;
provided, however, that the foregoing shall not obligate the Company, the
Guarantor or any other Subsidiary to preserve any such right or franchise if
the Company, the Guarantor or any other Subsidiary shall determine that the
preservation thereof is no longer desirable in the conduct of its business or
the business of such other Subsidiary.

                 Section 1008.    Waiver of Certain Covenants.

                 The Company or the Guarantor, as the case may be, may omit in
any particular instance to comply with any term, provision or condition set
forth in Sections 1005, 1006 or 1007 with respect to the Securities of any
series if before the time for such compliance the Holders of at least a
majority in principal amount of the Outstanding Securities of such series, by
Act of such Holders, either shall waive such compliance in such instance or
generally shall have waived compliance with such term, provision or condition,
but no such waiver shall extend to or affect such term, provision or condition
except to the extent so expressly waived, and, until such waiver shall become
effective, the obligations of the Company and the Guarantor and the duties of
the Trustee in respect of any such term, provision or condition shall remain in
full force and effect.


                  Section 1009.    Company Statement as to Compliance; Notice
                                   of Certain Defaults.

                 (a)      Each of the Company and the Guarantor shall deliver
to the Trustee, within 120 days after the end of each fiscal year, a written
statement (which need not be contained in or accompanied by an Officers'
Certificate) signed by the principal executive officer, the principal financial
officer or the principal accounting officer of the Company and the Guarantor,
respectively, stating that

                 (1)      a review of the activities of the Company or the
         Guarantor, as the case may be, during such year and of its performance
         under this Indenture has been made under his or her supervision, and

                 (2)      to the best of his or her knowledge, based on such
         review, (i) the Company  or the Guarantor, as the case may be, has
         complied with all the conditions and covenants imposed on it under
         this Indenture throughout such year, or, if there has been a default
         in the fulfillment of any such condition or covenant, specifying each
         such default known to him or her and the nature and status thereof,
         and (ii) no event has occurred and is continuing which is, or after
         notice or lapse of time or both would become, an Event of Default, or,
         if such an event has occurred and is continuing, specifying each such
         event known to him and the nature and status thereof.

                 (b)      Each of the Company and the Guarantor shall deliver
to the Trustee, within five days after the occurrence thereof, written notice
of any Event of Default or any event which after notice or lapse of time or
both would become an Event of Default.

                            REDEMPTION OF SECURITIES


                 Section 1101.    Applicability of Article.

                 Redemption of Securities of any series at the option of the
Company as permitted or required by the terms of such Securities shall be made
in accordance with the terms of such Securities and (except as otherwise
provided herein or pursuant hereto) this Article.


                 Section 1102.    Election to Redeem; Notice to Trustee.

                 The election of the Company to redeem any Securities shall be
evidenced by or pursuant to a Board Resolution or an Officers' Certificate.  In
case of any redemption at the election of the Company of (a) less than all of
the Securities of any series or (b) all of the Securities of any series, with
the same issue date, interest rate or formula, Stated Maturity and other terms,
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.

                 Section 1103.    Selection by Trustee of Securities to be
                                  Redeemed.

                 If less than all of the Securities of any series with the same
issue date, interest rate or formula, Stated Maturity and other terms 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, by such method
as the Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions of the principal amount of Registered
Securities of such series; provided, however, that no such partial redemption
shall reduce the portion of the principal amount of a Registered Security of
such series not redeemed to less than the minimum denomination for a Security
of such series established herein or pursuant hereto.

                 The Trustee shall promptly notify the Company and the Security
Registrar (if other than itself) 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 of such Securities which has been or is
to be redeemed.

<PAGE>   95

                 Section 1104.    Notice of Redemption.

                 Notice of redemption shall be given in the manner provided in
Section 106, not less than 30 nor more than 60 days prior to the Redemption
Date, unless a shorter period is specified in the Securities to be redeemed, to
the Holders of Securities to be redeemed.  Failure to give notice by mailing in
the manner herein provided to the Holder of any Registered Securities
designated for redemption as a whole or in part, or any defect in the notice to
any such Holder, shall not affect the validity of the proceedings for the
redemption of any other Securities or portion thereof.

                 Any notice that is mailed to the Holder of any Registered
Securities in the manner herein provided shall be conclusively presumed to have
been duly given, whether or not such Holder receives the notice.

                 All notices of redemption shall state:

                 (a)      the Redemption Date,

                 (b)      the Redemption Price,

                 (c)      if less than all Outstanding Securities of any series
are to be redeemed, the identification (and, in the case of partial redemption,
the principal amount) of the particular Security or Securities to be redeemed,

                 (d)      in case any Security is to be redeemed in part only,
the notice which relates to such Security shall state that on and after the
Redemption Date, upon surrender of such Security, the Holder of such Security
will receive, without charge, a new Security or Securities of authorized
denominations for the principal amount thereof remaining unredeemed,

                 (e)      that, on the Redemption Date, the Redemption Price
shall become due and payable upon each such Security or portion thereof to be
redeemed, and, if applicable, that interest thereon shall cease to accrue on
and after said date,

                 (f)      the place or places where such Securities, together
(in the case of Bearer Securities) with all Coupons appertaining thereto, if
any, maturing after the Redemption Date, are to be surrendered for payment of
the Redemption Price and any accrued interest and Additional Amounts pertaining
thereto,

                 (g)      that, unless otherwise specified in such notice,
Bearer Securities of any series, if any, surrendered for redemption must be
accompanied by all Coupons 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, unless security or indemnity satisfactory to the Company, the
Trustee and any Paying Agent is furnished,





                                       87
<PAGE>   96
                 (h)      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 the Redemption Date pursuant to Section 305 or otherwise, the
last date, as determined by the Company, on which such exchanges may be made,

                 (i)      the CUSIP number or the Euroclear or the Cedel
reference numbers of such Securities, if any (or any other numbers used by a
Depository to identify such Securities).

                 A notice of redemption mailed as contemplated by Section 106
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 1105.    Deposit of Redemption Price.

                 On or prior to any Redemption Date, the Company shall deposit,
with respect to the Securities of any series called for redemption pursuant to
Section 1104, 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 1003) an amount of money in the applicable Currency sufficient to pay
the Redemption Price of, and (except if the Redemption Date shall be an
Interest Payment Date, unless otherwise specified pursuant to Section 301 or in
the Securities of such series) any accrued interest on and Additional Amounts
with respect thereto, all such Securities or portions thereof which are to be
redeemed on that date.


                 Section 1106.    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 void.  Upon surrender of any such
Security for redemption in accordance with said notice, together with all
Coupons, if any, appertaining thereto maturing after the Redemption Date, such
Security shall be paid by the Company at the Redemption Price, together with
any accrued interest and Additional Amounts to the Redemption Date; provided,
however, that, except as otherwise provided in or pursuant to this Indenture or
the Bearer Securities of such series, installments of interest on Bearer
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable only upon presentation and surrender of Coupons for such interest (at
an Office or Agency located outside the United States except as otherwise
provided in Section 1002), and provided, further, that,





                                       88
<PAGE>   97
except as otherwise specified in or pursuant to this Indenture or the
Registered Securities of such series, installments of interest on Registered
Securities 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 Regular Record
Dates therefor 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 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, or the surrender of such
missing Coupon or Coupons 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 any interest or Additional Amounts represented by
Coupons shall be payable only upon presentation and surrender of those Coupons
at an Office or Agency for such Security located outside of the United States
except as otherwise provided in Section 1002.

                 If any Security called for redemption shall not be so paid
upon surrender thereof for redemption, the principal and any premium, until
paid, shall bear interest from the Redemption Date at the rate prescribed
therefor in the Security.


                 Section 1107.    Securities Redeemed in Part.

                 Any Registered Security which is to be redeemed only in part
shall be surrendered at any Office or Agency for such Security (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, the Guarantees of the Guarantor shall be endorsed on 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, containing identical terms and provisions, 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.  If a Security in global form is so surrendered, the Company shall
execute, and the Trustee shall authenticate and deliver to the U.S. Depository
or other Depository for such Security in global form as shall be specified in
the Company Order with respect thereto to the Trustee, without service charge,
a new Security in global form in a denomination equal to and in exchange for
the unredeemed portion of the principal of the Security in global form so
surrendered.

                       REPAYMENT AT THE OPTION OF HOLDERS


                 Section 1201. Applicability of Article.

                 Securities of any series which are repayable at the option of
the Holders thereof before their Stated Maturity shall be repaid in accordance
with the terms of the Securities of such series. The repayment of any principal
amount of Securities pursuant to such option of the Holder to require repayment
of Securities before their Stated Maturity, for purposes of Section 309, shall
not operate as a payment, redemption or satisfaction of the Indebtedness
represented by such Securities unless and until the Company, at its option,
shall deliver or surrender the same to the Trustee with a directive that such
Securities be canceled. Notwithstanding anything to the contrary contained in

                 Section 1401.    Purposes for Which Meetings May Be Called.

                 A meeting of Holders of Securities of any series may be called
at any time and from time to time pursuant to this Article to make, give or
take any request, demand, authorization, direction, notice, consent, waiver or

held at such time and at such place in the Borough of Manhattan, The City of

general terms the action proposed to be taken at such meeting, shall be given,
in the manner provided in Section 106, not less than 21 nor more than 180 days
prior to the date fixed for the meeting.

                 (b)      In case at any time the Company or the Guarantor (in
each case, by or pursuant to a Board Resolution) or the Holders of at least 10%
in principal amount of the Outstanding Securities of any series shall have
requested the Trustee to call a meeting of the Holders of Securities of such
series for any purpose specified in Section 1401, by written request setting

principal amount of the Outstanding Securities of a series, the Persons
entitled to vote 66-2/3% in principal amount of the Outstanding Securities of
such series shall constitute a quorum.  In the absence of a quorum within 30
minutes after the time appointed for any such meeting, the meeting shall, if
convened at the request of Holders of Securities of such series, be dissolved.
In any other case the meeting may be adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such meeting.  In the absence of a quorum at any such adjourned meeting, such
adjourned meeting may be further adjourned for a period of not less than 10

meeting shall state expressly the percentage, as provided above, of the
principal amount of the Outstanding Securities of such series which shall

                 Except as limited by the proviso to Section 902, any
resolution presented to a meeting or adjourned meeting duly reconvened at which
a quorum is present as aforesaid may be adopted only by the affirmative vote of

further, that, except as limited by the proviso to Section 902, any resolution
with respect to any request, demand, authorization, direction, notice, consent,
waiver or other Act which this Indenture expressly provides may be made, given
or taken by the Holders of a specified percentage, which is less than a

                 Any resolution passed or decision taken at any meeting of
Holders of Securities of any series duly held in accordance with this Section
shall be binding on all the Holders of Securities of such series and the

                 (a)      Notwithstanding any other provisions of this
Indenture, the Trustee may make such reasonable regulations as it may deem
advisable for any meeting of Holders of Securities of such series in regard to
proof of the holding of Securities of such series and of the appointment of
proxies and in regard to the appointment and duties of inspectors of votes, the
submission and examination of proxies, certificates and other evidence of the
right to vote, and such other matters concerning the conduct of the meeting as
it shall deem appropriate.  Except as otherwise permitted or required by any
such regulations, the holding of Securities shall be proved in the manner
specified in Section 104 and the appointment of any proxy shall be proved in
the manner specified in Section 104 or by having the signature of the person
executing the proxy witnessed or guaranteed by any trust company, bank or
banker authorized by Section 104 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 104 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, the Guarantor or 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 in like manner 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
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 or proxy shall be entitled to one vote for each $1,000 principal amount
of 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 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 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.

                                  Meetings.

                 The vote upon any resolution submitted to any meeting of
Holders of 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 triplicate of all votes cast at the meeting.  A record, at least in
triplicate, 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 said 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 said 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, another to the Guarantor 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.

         person arises solely as a result of a revocable proxy delivered in
         response to a proxy or consent solicitation that is made pursuant to,
         and in accordance with, the Exchange Act of 1934 and the applicable
         rules and regulations thereunder and is not then reportable on

         shares of Common Stock receive, directly or indirectly, (A) 75% or
         more of the common stock of the sole surviving or continuing
         Corporation outstanding immediately following the consummation of such
         consolidation or merger and (B) securities representing 75% or more of
         the combined voting power of the Voting Stock of the sole surviving or

                 (e) the name and address of the Trustee and the Office or

         as to which a Change in Control Purchase Notice has been duly given
         and not withdrawn will be paid promptly following the later of the
         Change in Control Purchase Date or the time of surrender of such
         Security as described in (f);

                 (h) the procedures the Holder must follow to exercise rights

                                       96
<PAGE>   105
         The delivery of the Security, by hand or by registered mail prior to,
on or after the Change in Control Purchase Date (together with all necessary
endorsements), to the Trustee or to an Office or Agency shall be a condition
precedent to the obligation of the Company to pay to the Holder the Change in
Control Purchase Price therefor; provided, however, that such Change in Control
Purchase Price shall be so paid pursuant to this Section 1501 only if the
Security so delivered to the Trustee or such Office or Agency shall conform in
all respects to the description thereof set forth in the related Change in
Control Purchase Notice.

         Notwithstanding anything herein to the contrary, any Holder delivering
to the Trustee or to an Office or Agency, the Change in Control Purchase Notice
contemplated by this Section 1501(3) shall have the right to withdraw such
Change in Control Purchase Notice at any time prior to or on the Change in
Control Purchase Date by delivery of a written notice of withdrawal to the
Trustee or to such Office or Agency in accordance with Section 1502.


                 Section 1502.  Effect of Change in Control Purchase Notice.

                 Upon receipt by the Company of the Change in Control Purchase
Notice specified in Section 1501(3), the Holder of the Security in respect of
which such Change in Control Purchase Notice was given shall (unless such
Change in Control Purchase Notice is withdrawn as specified in the following
paragraph) thereafter be entitled to receive solely the Change in Control
Purchase Price with respect to such Security.  Such Change in Control Purchase
Price shall be paid to such Holder promptly following the later of (x) the
Change in Control Purchase Date, as the case may be, with respect to such
Security (provided the conditions in Section 1501(3), as applicable, have been
satisfied) and (y) the time of delivery of such Security to the Trustee or to
an Office or Agency by the Holder thereof in the manner required by Section
1501(3), as applicable.

                 A Change in Control Purchase Notice may be withdrawn by means
of a written notice of withdrawal delivered to the office of the Trustee or to
an Office or Agency at any time prior to the close of business on the Change in
Control Purchase Date, specifying:

                 (a) the certificate number or numbers of the Security or
Securities in respect of which such notice of withdrawal is being submitted;

                 (b) the principal amount of the Security or Securities with
respect to which such notice of withdrawal is being submitted; and

                 (c) the principal amount, if any, of such Security or
Securities which remains subject to the original Change in Control Purchase
Notice, and which has been and will be delivered for purchase by the Company.

                 There shall be no purchase of any Securities pursuant to
Section 1501 if there has occurred and in continuing an Event of Default (other
than a default in the payment of the Change in Control Purchase Price).


                 Section 1503.  Deposit of Change in Control Purchase Price.

                 Prior to 12:00 Noon (local time in The City of New York) on
the Business Day following the Change in Control Purchase Date, the Company
shall deposit with the Trustee (or, if the Guarantor or a Subsidiary or an
Affiliate of any of them is acting as Paying Agent, shall segregate and hold in
trust as provided in Section 1003) an amount of cash in immediately available
funds or securities, if expressly permitted hereunder, sufficient to pay the
aggregate Change in Control Purchase Price of all the Securities or portions
thereof which are to be purchased.  If a deposit is made with the Trustee of
the aforesaid amount of cash or securities, the Securities or portions thereof
with respect to which a Change in Control Purchase Notice has been delivered
and not validly withdrawn shall become due and payable as of the Business Day
following the applicable Change in Control Purchase Date, and on and after such
date interest payable in respect of such Securities shall cease and all other
rights of the Holders thereof shall terminate, other than the right to receive
the Change in Control Purchase Price upon delivery of such Securities to the
Trustee.

                 Section 1504.    Covenant to Comply With Securities Laws Upon
                                  Purchase of Securities.

                 In connection with any purchase of securities under Section
1501 hereof, the Company shall (a) comply with Rule 13e-4 under the Exchange
Act of 1934, if applicable, (b) file the related Schedule 13E-4 (or any
successor schedule, form or report) under the Exchange Act of 1934, if
applicable, and (c) otherwise comply with all Federal and state securities laws
regulating the purchase of the Securities (including positions of the
Commission under applicable no-action letters) so as to permit the rights and
obligation under Section 1501 to be exercised in the time and in the manner
specified in Section 1501 and 1502.


                 Section 1505.  Repayment to the Company.

                 The Trustee shall return to the Company any cash, together
with interest or dividends, if any, thereon (subject to the provisions of
Section 605) held by it for the payment of the Change in Control Purchase Price
of the Securities that remain unclaimed as provided in the Securities;
provided, however, that to the extent the aggregate amount of cash deposited by
the Company pursuant to Section 1503 exceeds the aggregate Change in Control
Purchase Price of the Securities or portions thereof to be purchased, then
promptly after the Change in Control Purchase Date, the Trustee shall return
any such excess to the Company together with interest or dividends, if any,
thereon (subject to the provisions of Section 605).

                 Section 1601. Guarantee.

                 The Guarantor hereby irrevocably and unconditionally
guarantees to each Holder of a Security authenticated and delivered by the
Trustee, and to the Trustee on behalf of such Holder, the due and punctual
payment of the principal of and any premium and interest on and any Additional
Amounts with respect to such Security and the due and punctual payment of any
payments provided for pursuant to the terms of such Security and any Coupons
appertaining thereto, when and as the same shall become due and payable,
whether at the State Maturity, by declaration of acceleration, call for
redemption or repayment or otherwise, in accordance with the terms of such
Security, any such Coupons and this Indenture, and any and all other amounts
owed by the Company to the Trustee or the Holders under the terms of this
Indenture.  This guarantee will not be discharged with respect to any
Securities of any series or Coupons appertaining thereto except by payment in
full of the principal thereof, premium, if any, and interest thereon and all
other amounts payable thereunder and under this Indenture with respect thereto.
The Guarantor hereby expressly waives its right to require the Trustee to
pursue or exhaust its legal or equitable remedies against the Issuer prior to
exercising its rights under this guarantee.   In case of the failure of the
Company punctually to make any such payment, the Guarantor hereby agrees to
cause such payment to be made punctually when and as the same shall become due
and payable, whether at the Stated Maturity or by declaration of acceleration,
call for redemption or repayment or otherwise, and as if such payment were made
by the Company.

                 The Guarantor hereby agrees that any amounts to be paid by it
hereunder shall be paid without deduction or withholding for or on account of
any and all present or future tax, duty,  assessment or governmental charge
imposed upon or as a result of such payment by the Government of the United
States, or any state or other political subdivision or taxing authority thereof
or therein, or if deduction or withholding of any such tax, duty, assessment or
charge shall at any time be required by or on behalf of the Government of the
United States or any such state, political subdivision or taxing authority, the
Guarantor shall pay such additional amount in respect of principal, premium, if
any, and interest, if any, as may be necessary in order that the net amounts
paid to the Holder of a Security or the Trustee on behalf of the Holder of such
Security, as the case may be, pursuant to this guarantee after such deduction
or withholding shall not be less than the amount provided for in such Security
to be then due and payable; except that no such additional amount shall be
payable in respect of any Security to any Holder (a) who is subject to such
tax, duty, assessment or governmental charge in respect of such Security by
reason of his being connected with the United States otherwise than merely by
the holding or ownership of such Security, or (b) who is not dealing at arm's
length with the Guarantor (within the meaning of the Internal Revenue Code as
amended from time to time).

<PAGE>   108
                 The Guarantor hereby agrees that its obligations hereunder
shall be as if it were principal debtor and not merely surety, and shall be
absolute and unconditional, irrespective of the validity, regularity or
enforceability of any Security or this Indenture, the absence of any action to
enforce the same, any waiver or consent by the Holder of such Security or by the
Trustee with respect to any provisions thereof or of this Indenture, the
obtaining of any judgment against the Company or any action to enforce the same
or any other circumstances which might otherwise constitute a legal or equitable
discharge or defense of a guarantor. The Guarantor hereby waives the benefits of
division and discussion, diligence, presentment, demand of payment, filing of
claims with a court in the event of merger, insolvency or bankruptcy of the
Company, any right to require a proceeding first against the Company, protest or
notice with respect to any Security or the indebtedness evidenced thereby and
all demands whatsoever, and covenants that no guarantee (including any Guarantee
endorsed on a Security) will be discharged in respect of any Security except
by complete performance of the obligations contained in such Security and in
this guarantee. The Guarantor hereby agrees that, in the event of a default in
payment of principal (or premium, if any) or interest, if any, on or Additional
Amounts with respect to any Security, or a default in any payment referred to
therein, legal proceedings may be instituted by the Trustee on behalf of, or by,
the Holder of such Security, on the terms and conditions set forth in this
Indenture, directly against the Guarantor to enforce this guarantee without
first proceeding against the Company.

                 The Guarantor shall be subrogated to all rights of the Holders
of the Securities of a particular series against the Company in respect of any
amounts paid by the Guarantor on account of such Securities pursuant to the
provisions of this guarantee or this Indenture; provided, however, that the
Guarantor shall not be entitled to enforce or to receive any payments arising
out of, or based upon, such right of subrogation until the principal of, any
premium and interest on, and Additional Amounts with respect to, all Securities
of such series issued hereunder shall have been paid in full.

                 Section 1602. Execution and Delivery of Guarantees.

                 The Guarantees to be endorsed on the Securities of each series
shall include the terms of the guarantee set forth in Section 202 (except that
references to premium and interest need be included only if any premium or
interest, respectively, is provided for in the terms of such series) and any
other terms that may be set forth in the form established pursuant to Section
202 with respect to such series. The Guarantor hereby agrees to execute the
Guarantees, in a form established pursuant to Section 202, to be endorsed on
each Security authenticated and delivered by the Trustee.

                 The Guarantees shall be executed on behalf of the Guarantor by
its Chairman of the Board, a Vice Chairman of the Board, its President or one
of its Vice Presidents, under its corporate seal reproduced thereon attested by
its Secretary or one of its Assistant Secretaries.  The signature of any of
these officers on the Guarantees may be manual or facsimile.

                 Guarantees bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Guarantor shall
bind the Guarantor, notwithstanding that such  individuals or any of them have
cased to hold such offices prior to the authentication and delivery of such
Guarantees or did not hold such offices at the date of such Guarantees.





                                      100
<PAGE>   109
                 The delivery of any Security by the Trustee, after the
authentication thereof  hereunder, shall constitute due delivery of the
Guarantee endorsed thereon on behalf of the Guarantor. The Guarantor hereby
agrees that its Guarantee set forth in Section 202 and in this Article shall
remain in full force and effect notwithstanding any failure to endorse a
Guarantee on any Security.

                 This guarantee shall continue to be effective or be
reinstated, as the case may be, if at any time payment on any Security, in
whole or in part, is rescinded or must otherwise be restored to the Company or
the Guarantor upon the bankruptcy, liquidation or reorganization of the Company
or otherwise.


                               ARTICLE SEVENTEEN

                                 MISCELLANEOUS

                 Section 1701.    Submission to Jurisdiction

                 The Company hereby acknowledges and agrees for the benefit of
the Trustee and the Holders of Securities and Coupons that any judicial
proceedings instituted in relation to any matter arising out of this Indenture,
the Securities or the Coupons may be brought in any court having subject matter
jurisdiction in the Borough of Manhattan, The City of New York, New York
(including, without limitation, federal courts located in the Borough of
Manhattan, The City of New York, New York), and, by execution and delivery of
this Indenture, the Company hereby irrevocably accepts generally and
unconditionally, the jurisdiction of the aforesaid courts, acknowledges their
competence and irrevocably agrees to be bound by any judgment rendered in any
such proceeding.  The Company also irrevocably and unconditionally waives for
the benefit of the Trustee and the Holders of Securities and Coupons any
immunity from jurisdiction and any immunity from legal process (whether through
service or notice, attachment prior to judgment, attachment in aid of
execution, execution or otherwise) in respect of this Indenture.  The Company
hereby irrevocably designates and appoints for the benefit of the Trustee and
the Holders of Securities, Guarantees and Coupons for the term of this
Indenture CT Corporation, 1633 Broadway, New York, New York 10019 as its agent
to receive on its behalf service of all process (with a copy of all such
service of process to be delivered to CT Corporation, 1633 Broadway, New York,
New York 10019) brought against it with respect to any such proceeding in any
such court in the City of New York, such service being hereby acknowledged by
the Company to be effective and binding service on it in every respect whether
or not the Company shall then be doing or shall have at any time done business
in New York.  Such appointment shall be irrevocable so long as any of the
Securities or Coupons





                                      101
<PAGE>   110
or the obligations of the Company hereunder remain outstanding until the
appointment of a successor by the Company and such successor's acceptance of
such appointment.  Upon such acceptance, the Company shall notify the Trustee
of the name and address of such successor.  The Company further agrees for the
benefit of the Trustee and the Holders of the Securities and the Coupons to
take any and all action, including the execution and filing of any and all such
documents and instruments, as may be necessary to continue such designation and
appointment of said CT Corporation in full force and effect so long as any of
the Securities or Coupons or the obligations of the Company hereunder shall be
outstanding.  The Trustee shall not be obligated and shall have no
responsibility with respect to any failure by the Company to take such action.
Nothing herein shall affect the right to serve process in any other manner
permitted by any law or limit the right of the Trustee or any Holder to
institute proceedings against the Company in the courts of any other
jurisdiction or jurisdictions.


                 Section 1702.    Stamp Duty

                 The Company and the Guarantor, jointly and severally, agree to
pay or reimburse any Holder of Securities or Coupons for stamp duty or similar
governmental charges imposed upon this Indenture, any Securities or any
Coupons.

                 This instrument may be executed in any number of counterparts,
each of which so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same instrument.

                 IN WITNESS WHEREOF, the parties hereto have caused this
Indenture to be duly executed, and their respective corporate seals to be
hereunto affixed, all as of the day and year first above written.

                             6 1/2% NOTE DUE 2007

         APACHE FINANCE PTY LTD (A.C.N. 080 571 900), a proprietary company with
limited liability organized under the laws of the Australian Capital Territory,
Australia (the "Company", which term includes any successor corporation under
the Indenture hereinafter referred to), for value received hereby promises to
pay to CEDE & CO., or registered assigns, the principal sum of One Hundred 
Seventy Million Dollars on December 15, 2007 ("Stated Maturity") and to pay
interest thereon from December 9, 1997 or from the most recent date in respect
of which interest has been paid or duly provided for, on June 15 and December 15
of each year (each, an "Interest Payment Date"), commencing June 15, 1998, and
at Stated Maturity or upon such other date on which the principal of this Note
becomes due and payable, whether by declaration of acceleration, notice of
redemption or notice of option to elect repayment  or otherwise, and including
any Redemption Date or Change in Control Purchase Date (each such date,
"Maturity"), at the rate of 6 1/2% per annum, until the principal hereof is paid
or duly made available for payment.  The interest so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in the
Indenture referred to below, be paid to the Person in whose name this Note (or
one or more Predecessor Securities) is registered as of the close of business on
June 1 or December 1, as the case may be (whether or not a Business Day), next
preceding such Interest Payment Date (each such date, a "Regular Record Date").
Any such interest which is payable, but is not punctually paid or duly provided
for, on any Interest Payment Date shall forthwith cease to be payable to the
Holder of this Note on such Regular Record Date, and shall be paid to the Person
in whose name this Note (or one or more Predecessor Securities) is registered at
the close of business on a Special Record Date for the payment of such defaulted
interest to be fixed by the Trustee, notice whereof shall be given to the Holder
of this Note not less than 10 days prior to such Special Record Date, or may be
paid in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Notes may be listed, and upon such notice as
may be required by such exchange, all as more fully provided in the Indenture.
Any interest paid on this Note shall be increased to the extent necessary to pay
Additional Amounts as set forth in this Note.

         Payment of the principal of, and any premium and interest on, this
Note will be made at the office or agency maintained for that purpose in
the Borough of Manhattan, The City of New York, in such coin or currency of the
United States of America as at the time of payment is legal tender for payment
of public and private debts; provided, however, that payment of interest may be
made at the option of the Company by check mailed to the Person in whose name
this Note is registered at the close of business on the related Record
Date; provided further, that, notwithstanding anything else contained herein,
if this Note is a Global Security and is held in book-entry form through
the facilities of the Depository, payments on this Note will be made to
the Depository or its nominee in accordance with the arrangements then in
effect between the Trustee and the Depository.

                              6 1/2% NOTE DUE 2007

         This Note is one of a duly authorized issue of Securities of the
Company issued under an Indenture, dated as of December 9, 1997 (the
"Indenture"), among the Company, Apache Corporation (the "Guarantor") and The
Chase Manhattan Bank  (the "Trustee", which term includes any successor trustee
under the Indenture), designated as the 6 1/2% Notes due 2007 (the "Notes").
Reference is made to the Indenture for a statement of the respective rights,
limitations of rights, duties and immunities thereunder of the Company, the
Guarantor, the Trustee and the Holders of the Notes and of the terms upon which
the Notes are, and are to be, authenticated and delivered.  All terms used in
this Note and the Guarantee set forth below which are not defined herein and
which are defined in the Indenture shall have the meanings assigned to them in
the Indenture.

         The Indenture provides for the defeasance of the Notes, the
Guarantees and certain covenants in certain circumstances.

         This Note is unsecured as to payment of principal, interest and
premium, if any, and ranks pari passu with all other unsecured unsubordinated
indebtedness of the Company.

         Interest payments on this Note will include interest accrued to
but excluding the applicable Interest Payment Date or Maturity hereof, as the
case may be.  Interest payments for this Note shall be computed and paid
on the basis of a 360-day year of twelve 30-day months.

         In the case where the applicable Interest Payment Date or Maturity
with respect hereto, as the case may be, does not fall on a Business Day,
payment of principal or interest otherwise payable on such day need not be made
on such day, but may be made on the next succeeding Business Day with the same
force and effect as if made on the Interest Payment Date or at Maturity and no
interest shall accrue with respect to such payment for the period from and
after the Interest Payment Date or such Maturity, as the case may be, to the
date of payment.

         The Notes will not be subject to any sinking fund and, except as
provided in the Indenture or herein, will not be redeemable or repayable prior
to their Stated Maturity.

         If any Event of Default with respect to the Notes shall occur and
be continuing, the principal of the Notes may be declared due and payable
in the manner and with the effect provided in the Indenture.

         As set forth in, and subject to the provisions of, the Indenture, no
Holder of any Note will have any right to institute any proceeding with
respect to the Indenture, the Notes or the Guarantees, or for any remedy
thereunder, unless (i) such Holder shall have previously given to the Trustee
written notice of a continuing Event of Default with respect to the Notes,
(ii) the Holders of not less than 25% in principal amount of the Outstanding
Notes shall have made written request, and offered reasonable indemnity,
to the Trustee to institute such proceeding as Trustee, (iii) the Trustee shall
have failed to institute such proceeding within 60 days after receipt of such
written notice, request and offer of indemnity and (iv) the Trustee shall not
have received from the Holders of a majority in principal amount of the
Outstanding Notes a direction inconsistent with such request within such
60 day period; provided, however, that such limitations do not apply to a suit
instituted by the Holder hereof for the enforcement of payment of the principal
of and premium, if any, or any interest on this Note on or after the
respective due dates expressed herein or to require the purchase of its
Notes by the Company upon the occurrence of a Change in Control in
accordance with the Indenture.

         The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the Guarantor and the rights of the Holders of the Securities of
each series thereunder to be affected under the Indenture at any time by the
Company and the Trustee with the consent of the Holders of not less than
66-2/3% in aggregate principal amount of such Securities then Outstanding of
each series to be affected.  The Indenture also contains provisions permitting
the Holders of a percentage of not less than a majority in principal amount of
the Securities of each series thereunder at the time Outstanding, on behalf of
the Holders of all Securities of such series, to waive compliance by the Company
with certain restrictive provisions of the Indenture and certain past defaults
under the Indenture and their consequences.  Any such consent or waiver by the
Holder of this Note shall be conclusive and binding upon such Holder and upon
all future Holders of any Note issued upon the registration of transfer hereof
or in exchange for or in lieu hereof, whether or not notation of such consent or
waiver is made upon this Note.  Notwithstanding the foregoing, no consent of
Holders shall be required to advance the Stated Maturity of the Notes as
provided herein.

                                      2

         No reference to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and premium, if any, and
any interest on this Note at the times, places and rate, and in the coin
or currency, herein prescribed.

         The Notes are issuable only in fully registered form in
denominations of $1,000 and integral multiples in excess thereof.  As provided
in the Indenture and subject to certain limitations therein set forth, this
Note is exchangeable for a like aggregate principal amount of Notes
of this series and of like tenor of any authorized denomination, as requested
by the Holder surrendering the same.  As provided in the Indenture and subject
to certain limitations therein set forth, the transfer of this Note is
registrable in the Security Register, upon surrender of this Note for
registration of transfer at the office or agency of the Company in any place
where the principal of and premium, if any, and any interest on this Note
are payable or at such other offices or agencies as the Company may designate,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to, the Company and the Security Registrar or any transfer agent
duly executed by the registered owner hereof or his attorney duly authorized in
writing, and thereupon one or more new Notes of this series and of like
tenor, of authorized denominations and for the same aggregate principal amount
and Stated Maturity will be issued to the designated transferee or transferees.

         The Notes will be redeemable as a whole or in part, at the option
of the Company at any time, at a redemption price equal to the greater of (i)
100% of their principal amount or (ii) the sum of the present values of the
remaining scheduled payments of principal and interest thereon discounted to
the Redemption Date on a semiannual basis (assuming a 360-day year consisting
of twelve 30-day months) at the Treasury Yield, plus               basis
points, plus in each case accrued interest on the principal amount being
redeemed to the Redemption Date.

         "Treasury Yield" means, with respect to any Redemption Date, the rate
per annum equal to the semiannual equivalent yield to maturity of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such Redemption Date.

         "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term to Stated Maturity of the Notes that would be utilized, at
the time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the
remaining term to Stated Maturity of the Notes.  "Independent Investment Banker"
means Salomon Brothers Inc or, if such firm is unwilling or unable to select
the Comparable Treasury Issue, an independent investment banking institution of
national standing appointed by the Trustee.

         "Comparable Treasury Price" means, with respect to any Redemption
Date, (i) the average of five Reference Treasury Dealer Quotations for such
Redemption Date, after excluding the highest and lowest such Reference Treasury
Dealer Quotations, or (ii) if the Trustee obtains fewer than five such
Reference Treasury Dealer Quotations, the average of all such Quotations.
"Reference Treasury Dealer Quotations" means, with respect to each Reference
Treasury Dealer and any Redemption Date, the average, as determined by the
Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the
third Business Day preceding such Redemption Date.

         "Reference Treasury Dealer" means each of Salomon Brothers Inc, Chase
Securities Inc., Goldman Sachs & Co. and  UBS Securities LLC and their 
respective successors; provided however, that if any of the foregoing shall 
cease to be a primary U.S. Government securities dealer in New York City (a 
"Primary Treasury Dealer"), the Company shall substitute therefor another 
Primary Treasury Dealer.

         If as a result of any change in or any amendment to the laws,
regulations or published tax rulings of the "applicable taxing jurisdiction"
(as hereinafter defined) affecting taxation, or any change in the official
administration, application or interpretation of such laws, regulations or
published tax rulings either generally or in relation to the Notes, which
change or amendment becomes effective on or after the original issue date of
the Notes or which change in official administration, application or
interpretation shall not have been available to the public prior to such issue
date, it is determined by the Company that (a) the Company would be required to
pay any Additional Amounts pursuant to the Indenture or the terms of the
Notes in respect of interest on the next succeeding Interest Payment Date
and (b) such obligation cannot be avoided by the Company or the Guarantor
taking reasonable measures available to it, the Company may, at its option,
redeem all (but not less than all) the Notes upon not less than 30 nor
more than 60 days' written notice as provided in the Indenture, at a Redemption
Price equal to 100% of the principal amount thereof plus accrued interest to
the date fixed for redemption; provided, however, that (a) no such notice of
redemption may be given earlier than 60 days prior to the earliest date on
which the Company would be obligated to pay such Additional Amounts were a
payment then due in respect of the Notes, and (b) at the time any such
redemption notice is given, such obligation to pay such Additional Amounts must
remain in effect. If (a) the Company shall have on any date (the

                                       3
<PAGE>   4
"Succession Date") consolidated with or merged into, or conveyed or transferred
or leased its properties and assets as an entirety or substantially as an
entirety to, any Successor which is organized under the laws of any
jurisdiction other than the United States of America, any State thereof or the
District of Columbia or the jurisdiction in which the Company is organized, (b)
as  result of any change in or any amendment to the laws, regulations or
published tax rulings of such jurisdiction or organization, or of any political
subdivision or taxing authority thereof or therein, affecting taxation, or any
change in the official administration, application or interpretation of such
laws, regulations or published tax rulings either generally or in relation to
the Notes, which change or amendment becomes effective on or after the
Succession Date or which change in official administration, application or
interpretation shall not have been available to the public prior to such
Succession Date and is notified to the Company, such Successor would be
required to pay any Successor Additional Amounts pursuant to the Indenture or
the terms of the Notes in respect of interest on any Notes on the
next succeeding Interest Payment Date and (c) such obligation cannot be avoided
by the Company or such Successor taking reasonable measures available to it,
such Company or Successor may at its option, redeem all (but not less than all)
of the Notes, upon not less than 30 nor more than 60 days' written notice
as provided in the Indenture, at a Redemption Price equal to 100% of the
principal amount thereof plus accrued interest to the date fixed for
redemption; provided however, that (a) no such notice of redemption may be
given earlier than 60 days prior to the earliest date on which a Successor
would be obligated to pay such Successor Additional Amounts were a payment then
due in respect of the Notes, and (b) at the time any such redemption
notice is given, such obligation to pay such Successor Additional Amounts must
remain in effect.

         Holders of Notes to be redeemed will receive notice thereof by
first-class mail at least 30 and not more than 60 days prior to the Redemption
Date, as provided in the Indenture.

         Unless the Company defaults in payment of the redemption price, on and
after the redemption date interest will cease to accrue on the Notes or
portions thereof called for redemption.

         All payments of, or in respect of, principal of and any premium and
interest on this Note shall be made without withholding or deduction for,
or on account of, any present or future taxes, duties, levies, assessments or
governmental charges of whatever nature imposed or levied by or on behalf of
the jurisdiction (or any political subdivision or taxing authority thereof or
therein) in which the Company is incorporated or resident (or deemed for tax
purposes to be resident) (the "applicable taxing jurisdiction"), unless such
taxes, duties, levies, assessments or governmental charges are required by the
applicable taxing jurisdiction or any such subdivision or authority to be
withheld or deducted. In that event, the Company will pay by way of additional
interest such additional amounts of, or in respect of, principal of and any
premium and interest ("Additional Amounts") as will result (after deduction of
such taxes, duties, levies, assessments or governmental charges and any
additional taxes, duties, levies, assessments or governmental charges payable
in respect of such Additional Amounts) in the payment to the Holder of this
Note of the amounts which would have been payable in respect of this
Note had no such withholding or deduction been required, except that no
Additional Amounts shall be so payable for or on account of:

(a)      any tax, duty, levy, assessment or other governmental charge which
would not have been imposed but for the fact that such Holder:

         (i)     was a resident, domiciliary or national of, or engaged in
         business or maintained a permanent establishment or was physically
         present in, the applicable taxing jurisdiction or otherwise had some
         connection with the applicable taxing jurisdiction other than the mere
         ownership of this Note;

         (ii)    presented (if presentation is required) this Note for
         payment in the applicable taxing jurisdiction, unless this Note
         could not have been presented for payment elsewhere;

         (iii)   presented (if presentation is required) this Note as the
         case may be, more than 30 days after the date on which the payment in
         respect of this Note first became due and payable or provided
         for, whichever is later, except to the extent that the Holder would
         have been entitled to such Additional Amounts; if it had presented
         such Note for payment on any days within such period of 30 days;

         (iv)    directly or indirectly is taken to be an associate of the
         Company (as "associate" is defined in Division 16F of the Income Tax
         Assessment Act 1936 of the Commonwealth of Australia (the "Tax Act")
         (but on the basis that sub paragraphs 159GZC(1)(a)(ii), (1)(b)(i) and
         (1)(d)(i) of the Tax Act do not apply)); or

         (v)     entered into or participated in a scheme to avoid Australian
         interest withholding tax, being a scheme which the Company was neither
         a party to nor participated in, in respect of which the Australian
         Commissioner of Taxation has made a determination that Australian
         interest withholding tax is payable in respect of the amount.





                                       4

(b)      any estate, inheritance, gift, sale, transfer, personal property or
similar tax, assessment or other governmental charge;

(c)      any tax, assessment or other governmental charge which is payable
otherwise than by withholding or deduction from payments of, or in respect of,
principal of or any premium or interest on this Note;

(d)      any tax, assessment or other governmental charge that is imposed or
withheld by reason of the failure to comply by the Holder or the beneficial
owner of this Note with a request of the Company addressed to the Holder
(i) to provide information concerning the nationality, residence or identity of
the Holder or such beneficial owner or (ii) to make any declaration or other
similar claim or satisfy any information or reporting requirement, which, in
the case of (i) or (ii), is required or imposed by a statute, treaty,
regulation or administrative practice of the applicable taxing jurisdiction as
a precondition to exemption from all or part of such tax, assessment or other
governmental charge; or

(e)      any combination of items (a), (b), (c) and (d);

nor shall Additional Amounts be paid with respect to any payment of the
principal of or any premium or interest on this Note to any Holder who is
a fiduciary or partnership or other than the sole beneficial owner of such
payment to the extent such payment would be required by the laws of the
applicable taxing jurisdiction to be included in the income for tax purposes of
a beneficiary or settlor with respect to such fiduciary or a member of such
partnership or a beneficial owner who would not have been entitled to such
Additional Amounts had it been the Holder of this Note.

         The payment of principal of, or any premium or interest on, or in
respect of, this Note shall be deemed to include the payment of Additional
Amounts provided for in the Indenture or herein to the extent that, in such
context, Additional Amounts are, were or would be payable in respect thereof
pursuant to the Indenture or this Note.

         Subject to the terms and conditions of the Indenture, if any Change in
Control occurs prior to the Stated Maturity of the Notes, the Company
shall, at the option of the Holders thereof, purchase all Notes for which
a Change in Control Purchase Notice shall have been delivered as provided in
the Indenture and not withdrawn, by a date which shall be 35 Business Days
after the occurrence of such Change in Control, at a Change in Control Purchase
Price equal to 100% of the principal amount thereof plus accrued interest to
the Change in Control Purchase Date, which Change in Control Purchase Price
shall be paid in cash.

         Holders have the right to withdraw any Change in Control Purchase
Notice by delivering to the paying agent a written notice of withdrawal in
accordance with the provisions of the Indenture.

         If cash sufficient to pay the Change in Control Purchase Price of all
Notes or portions thereof to be purchased on the Change in Control
Purchase Date is deposited with the Trustee on the Change in Control Purchase
Date, interest shall cease to accrue on such Notes (or portions thereof)
and on and after the Change in Control Purchase Date the Holders thereof shall
have no other rights as such (other than the right to receive the Change in
Control Purchase Price upon surrender of such Notes).

         Subject to the terms of the Indenture, prior to due presentment of
this Note for registration of transfer, the Company, the Guarantor, the
Trustee and any agent of the Company, the Guarantor or the Trustee may treat
the Person in whose name this Note is registered as the owner hereof for
all purposes, whether or not this Note is overdue, and neither the
Company, the Guarantor, the Trustee nor any such agent shall be affected by
notice to the contrary.

         No service charge shall be made for any registration of transfer or
exchange of this Note, but, subject to certain limitations set forth in
the Indenture, the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

         The Indenture and this Note shall be governed by and construed in
accordance with the laws of the State of New York.

         This Note shall not be valid or become obligatory for any purpose
until the Trustee's Certificate of Authentication hereon shall have been
executed by the Trustee.

                                   GUARANTEE

     For value received, Apache Corporation, a corporation organized under the
laws of the State of Delaware (herein called the "Guarantor," which term
includes any successor corporation under the Indenture referred to in the
Security upon which this Guarantee is endorsed), hereby irrevocably and
unconditionally guarantees to the Holder of the Security upon which this
Guarantee is endorsed and to the Trustee on behalf of the Trustee and such
Holder the due and punctual payment of the principal of and any premium and
interest on, and any Additional Amounts with respect to, such Security, and any
other amount due and payable pursuant to the terms of the Indenture or payments
referred to therein, when and as the same shall become due and payable, whether
at the Stated Maturity, by declaration of acceleration, call for redemption or
repurchase or otherwise, according to the terms of such Security and of the
Indenture referred to therein.  In case of the failure of Apache Finance Pty
Ltd, a proprietary company with limited liability organized under the laws of
the Australian Capital Territory, Australia (herein called the "Company," which
term includes any successor corporation under such Indenture), punctually to
make any such payment of principal or any premium or interest on, or any
Additional Amounts with respect to such Security, the Guarantor hereby agrees
to cause any such payment to be made punctually when and as the same shall
become due and payable, whether at the Stated Maturity or by declaration of
acceleration, call for redemption or repurchase or otherwise, and as if such
payment were made by the Company.

     The Guarantor hereby agrees that its obligations hereunder shall be as if
it were principal debtor and not merely surety, and shall be absolute and
unconditional, irrespective of, and shall be unaffected by, any invalidity,
irregularity or unenforceability of such Security or such Indenture, any
failure to enforce the provisions of such Security or such Indenture, or any
waiver, modification or indulgence granted to the Company with respect thereto,
by the Holder of such Security or the Trustee or any other circumstance which
may otherwise constitute a legal or equitable discharge of a surety or
guarantor. The Guarantor hereby waives the benefits of division and discussion,
diligence, presentment, demand of payment, filing of claims with a court in the
event of merger, insolvency or bankruptcy of the Company, any right to require
a proceeding first against the Company, protest or notice with respect to such
Security or the indebtedness evidenced thereby and all demands whatsoever, and
covenants that this Guarantee will not be discharged except by strict and
complete performance of the obligations contained in such Security and this
Guarantee. The Guarantor hereby agrees that, in the event of a default in
payment of principal or any premium or interest on, or any Additional Amounts
with respect to such Security, or default in any payment referred to therein,
legal proceedings may be instituted by the Trustee on behalf of, or by, the
Holder of such Security, on the terms and conditions set forth in the
Indenture, directly against the Guarantor to enforce this Guarantee without
first proceeding against the Company.

     The Guarantor shall be subrogated to all rights of the Holder of such
Security and the Trustee against the Company in respect of any amounts paid to
such Holder by the Guarantor on account of such Security pursuant to the
provisions of this Guarantee or the Indenture; provided, however, that the
Guarantor shall not be entitled to enforce, or to receive any payments arising
out of or based upon, such right of subrogation until the principal of, and any
premium and interest on, and any Additional Amounts required with respect to
Securities issued under such Indenture shall have been paid in full.

     No reference herein to such Indenture and no provision of this Guarantee
or of such Indenture shall alter or impair the guarantee of the Guarantor,
which is absolute and unconditional, of the due and punctual payment of
principal, premium (if any), and interest on and any Additional Amounts with
respect to the Security upon which this Guarantee is endorsed.

     This Guarantee shall not be valid or obligatory for any purpose until the
certificate of authentication of the Security upon which this Guarantee is
endorsed shall have been manually executed by or on behalf of the Trustee under
such Indenture.

     All terms used in this Guarantee which are defined in such Indenture shall
have the meanings assigned to them in such Indenture.

     This Guarantee shall be deemed to be a contract made under the laws of the
State of New York, and for all purposes shall be governed by and construed in
accordance with the laws of the State of New York.

     This Guarantee is an unsecured obligation of the Guarantor, and ranks pari
passu with all other unsubordinated indebtedness of the Guarantor.

     IN WITNESS WHEREOF, the Guarantor has caused this Guarantee to be duly
executed under its corporate seal and dated the date on the face hereof.
