                        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 Commonwealth of Australia
(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 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 





                                       5


   6


(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 333-30073-01) 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 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 "1934 Act"), that are incorporated by reference therein.

                  foreign corporation 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 conduct of its
                  business requires such qualification, whether by reason 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 Company

                  transact business and is in good standing 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

                  each 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; and, except as described in the Prospectus,

                  the consequences of such conflict, breach, creation,

                  of the Company or the Guarantor and its subsidiaries

                  governmental authorization necessary to the ownership of its
                  property or to the conduct of its business, which violation or

                  affairs or business prospects of the Company or the Guarantor

                  presently conducted, except where the failure to possess such
                  licenses or authorizations or make such filings would not
                  materially adversely affect the condition, financial or
                  otherwise, or the results of operations, business affairs or
                  business prospects of the Company or the Guarantor and its

                  operated by them, except as set forth or incorporated by
                  reference in the Registration Statement or except where the
                  failure to own or possess the same would not materially
                  adversely affect 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 neither the Guarantor nor
                  any of its subsidiaries has received any notice of
                  infringement of or conflict with asserted rights of others
                  with respect to any trademarks, service marks or trade names
                  which, singly or in the aggregate, if the subject of an
                  unfavorable decision, ruling or finding, would materially
                  adversely affect the condition, financial or otherwise, or the
                  results of operations, business affairs or business prospects
                  of the Company or the Guarantor and its subsidiaries

                  lease by the Guarantor and its subsidiaries are held by them
                  under valid, subsisting and enforceable leases, in each case
                  free and clear of all mortgages, pledges, liens, security
                  interests, claims, restrictions or encumbrances and defects of
                  any kind, except such as (1) are described in the Prospectus,

                  exploration and production agreements, in each case that
                  secure payment of amounts not yet due and payable for the
                  performance of other inchoate obligations and are of a scope
                  and nature customary in connection with similar drilling and
                  producing operations or (3) those that do not 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.

                  (s) The information underlying the estimates of oil and gas
                  reserves as described in the Prospectus is complete and
                  accurate in all material respects (or, with regard to any
                  information underlying the estimates prepared by any petroleum
                  engineers retained by the seller of such oil and gas reserves,
                  is, to the best knowledge of the Company and the Guarantor
                  after reasonable investigation, complete and accurate in all
                  material respects); other than production of the reserves in
                  the ordinary course of business and intervening product price
                  fluctuations described in the Prospectus, the Company and the
                  Guarantor are not aware of any facts or circumstances that
                  would result in a material adverse change in the reserves or
                  the present value of future net cash flows therefrom as
                  described in the Prospectus. Estimates of such reserves and
                  present values comply in all material respects with the
                  applicable requirements of Regulation S-X and Industry Guide 2
                  under the 1933 Act.

                  (t) Neither the Company, nor the Guarantor or any of its other
                  subsidiaries, is required to be registered under the
                  Investment Company Act of 1940, as amended (the "1940 Act").

                  (u) The Guarantor has complied and will comply with the
                  provisions of Florida H.B. 1771, codified as Section 517.075
                  of the Florida Statutes, 1987, as amended, and all regulations
                  promulgated thereunder relating to issuers doing business in
                  Cuba.

                  (v) Except as described in the Registration Statement, (1)
                  neither the Guarantor nor any of its subsidiaries is in
                  violation of any local or foreign laws or regulations relating
                  to pollution or protection of human health, the environment
                  (including, without limitation, ambient air, surface water,
                  groundwater, land surface or subsurface strata) or wildlife,
                  including, without limitation, laws and regulations relating
                  to the release or threatened release of chemicals, pollutants,
                  contaminants, wastes, toxic substances, hazardous substances,
                  petroleum or petroleum products (collectively, "Hazardous
                  Materials") or to the manufacture, processing, distribution,
                  use, treatment, storage, disposal, transport or handling of
                  Hazardous Materials (collectively, "Environmental Laws"),
                  except 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 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 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 




                                       14


   15


                  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 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 



                                       15


   16


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
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 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 



                                       16


   17


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.

         (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 



                                       17


   18


                  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 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 




                                       18

   19


                  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 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 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 


                                       19






   20


                  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
                  business).

         SECTION 4. Conditions of Underwriters' Obligations. The obligations of
the Underwriters to purchase Offered Securities pursuant to this Agreement are
subject to the accuracy of the representations and warranties on the part of the
Company and the Guarantor herein contained, to the accuracy of the statements
which the Company's and the Guarantor's officers made in any certificate
furnished pursuant to the provisions hereof, to the performance by the Company
and the Guarantor of all of their respective covenants and other obligations
hereunder and under the Terms Agreement, and to the following further
conditions:

                  (a) At the Closing Time, no stop order suspending the
                  effectiveness of the Registration Statement or any Rule 462(b)
                  Registration Statement shall have been issued under the 1933
                  Act or proceedings therefor initiated or threatened by the
                  Commission.

                  (b) At the Closing Time, the Representatives shall have
                  received:

                           (1) The favorable opinion, dated as of the Closing
         Time, of Woodard, Hall & Primm, P.C., counsel to the Company and the
         Guarantor, to the effect that:

                                    (i) The Guarantor has been duly incorporated
                  and is validly existing as a corporation in good standing
                  under the laws of the State of Delaware.

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

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

                                    (iv) The Guarantee has been duly authorized
                  by the Guarantor 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, with respect to such Securities, constitute
                  the valid and binding obligation of the Guarantor, 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 Guarantor or by general equity principles, and
                  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.

                                    (v) The Offered Securities, in the form(s)
                  certified by the Company as of the Closing Time, have been
                  duly authorized for issuance, offer and sale pursuant to this
                  Agreement and, when issued, authenticated and delivered
                  pursuant to the provisions of this Agreement, any Delayed
                  Delivery Contract and the Indenture against payment of the
                  consideration therefor, will 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, moratorium or other

                  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; and each holder of Offered
                  Securities will be entitled to the benefits of the Indenture.



                                       21


   22



                                    (vi) The Offered Securities and the
                  Indenture conform in all material respects to the statements
                  relating thereto in the Prospectus; and the statements in the
                  Prospectus under the captions "Description of Notes" and
                  "Description of Debt Securities", insofar as they purport to
                  summarize certain provisions of documents specifically
                  referred to therein, are accurate summaries of such
                  provisions.

                                    (vii) The Indenture has been duly qualified
                  under the 1939 Act.

                                    (viii) The Registration Statement, including
                  any Rule 462(b) Registration Statement, has been declared
                  effective by the Commission under the 1933 Act and, to the
                  best of such counsel's knowledge, no stop order suspending the
                  effectiveness of the Registration 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.

                                    (x) The information contained in the
                  Prospectus under the caption "Tax Considerations - Certain
                  United States 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 Agreement and has validly and effectively
                  waived any objection 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 designate, appoint and empower and
                  pursuant to this Agreement has 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 in any federal or state court in
                  the State of New York, County of New York as provided in
                  Section 14 of this Agreement.

                  In rendering such opinion, counsel for the Company and the
                  Guarantor may rely (i) as to matters of fact upon the
                  representations of officers of the Company and the Guarantor
                  contained in any certificate delivered to such counsel and
                  certificates of public officials, which certificates shall be
                  attached to or delivered 




                                       22


   23


                  with such opinion, (ii) as to matters of the laws of Australia
                  upon the opinion of Arthur Robinson & Hedderwicks furnished
                  pursuant to this Agreement and (iii) as to the laws of the
                  State of New York applicable to the enforceability of the
                  Offered Securities and the Indenture upon the opinion of Brown
                  & Wood LLP. 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.

                           (2) The favorable opinion of Zurab S. Kobiashvili,
         General Counsel of the Guarantor, to the effect that:

                                    (i) The Guarantor has the corporate power
                  and authority to own, lease and operate its properties and to
                  conduct its business as described in the Prospectus and to
                  enter into and perform its obligations under this Agreement
                  and the Delayed Delivery Contracts, if any.

                                    (ii) To the best knowledge and information
                  of such counsel, the Guarantor is duly qualified as a foreign
                  corporation to transact business and is in good standing in
                  the State of Texas and in each other jurisdiction in which
                  such qualification is required, 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

                  operations, business affairs or business prospects of the

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

                  governmental agency or body, domestic or foreign, now pending,
                  or threatened against or affecting, the Guarantor or any of
                  its subsidiaries, which would be reasonably expected to result

                  otherwise, or in the results of operations, business affairs
                  or business prospects of the Guarantor and its subsidiaries

                  Agreement, the Delayed Delivery Contracts, if applicable, or
                  the Indenture or any transaction contemplated hereby or

                  reference as exhibits thereto, the descriptions thereof or
                  references thereto are correct in all material respects, and,
                  to the best of such counsel's knowledge and information, no
                  default exists in the due performance or observance of any
                  material obligation, agreement, covenant or conditions
                  contained in any contract, or other documents so described,
                  referred to, filed or incorporated by reference where the
                  consequences of such 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 Guarantor and its subsidiaries considered as one
                  enterprise.

                           In rendering such opinion, Zurab S. Kobiashvili may
                  rely as to matters of fact upon the representations of
                  officers of the Guarantor contained in any certificate

                  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.

                  of the State of Delaware, the laws of the State of Texas and
                  the laws of the United States of America.

                  standing in each jurisdiction in which such qualification is

                  or leasing of property or the conduct of business, except
                  where the failure so to qualify could not reasonably be

                  results of operations of the Company or its ability to perform

                  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,

                  against payment pursuant to the Terms Agreement, as
                  supplemented by this Agreement, or any Delayed Delivery

                  order or decree of any court or governmental agency or body in

                  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 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 



                                       26


   27


                  Memorandum and Articles of Association of the Company or any
                  applicable law, administrative regulation or administrative or

                  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 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 




                                       27


   28


                  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 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




                                       28

                  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) and (xi), 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 




                                       29



   30


         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 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, President or
                  Vice President and the Treasurer, the Assistant Treasurer, the
                  principal 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 its subsidiaries, (ii) the
                  representations and warranties of the Company contained in
                  Section 1 are true and correct as of the Closing Time and
                  (iii) the Company has performed or complied with all
                  agreements and satisfied all conditions on its part to be
                  performed or satisfied at or prior to the date of such
                  certificate, and (B) 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, dated as of the Closing Time, to the effect
                  that (i) there has been no such material adverse change with
                  respect to the Guarantor and its subsidiaries, (ii) the
                  representations and warranties of the Guarantor consolidated
                  as one enterprise contained in Section 1 are true and correct
                  as of the Closing Time, (iii) the Guarantor has performed or
                  complied with all agreements and satisfied all conditions on
                  its part to be performed or satisfied at or prior to the date
                  of such certificate and (iv) no stop order suspending the
                  effectiveness of the Registration Statement or any Rule 462(b)

                  that purpose have been initiated or threatened by the
                  Commission. As used in this Section 4(c), the term
                  "Prospectus" means the Prospectus in the form first 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 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 





                                       31


   32


                  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 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

                  Company and the Guarantor contained herein and the statements
                  in any certificates furnished by the Company and the Guarantor

         to the same effect as the opinions required by subsections (1), (2) and
         (3) of Section 4(b) hereof.

         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.

         SECTION 5. Payment of Expenses. The Company and the Guarantor, jointly
and severally, will pay all expenses incident to the performance of its

                  and any amendments or supplements thereto, and the delivery by
                  the Underwriters of the Prospectus and any amendments or

                  supplements and modifications thereto;

                  with the National Association of Securities Dealers, Inc.;

                  (l) any out-of-pocket expenses of the Underwriters incurred
                  with the approval of the Company;

                  (m) the cost of providing any CUSIP or other identification
                  numbers for the Offered Securities; and

                  with the issuance, sale and delivery of the Offered Securities
                  or the execution, delivery or performance of this Agreement or
                  the Indenture.

         If this Agreement is terminated by the Underwriters in accordance with
the provisions of Section 9, the Company and the Guarantor shall reimburse the
Underwriters for all of their out-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:




                                       34

   35


         (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 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 




                                       35

   36


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 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 




                                       36


   37

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 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
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.


                                       37


   38



         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 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.



                                       38


   39



         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 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

   40


receive notice pursuant to this Agreement by notice duly given in accordance
with the terms of this Section 11.

         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

                  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

                  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 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

                  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.

                  (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 







                                       41
   42


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.

                  (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 








                                       42
   43

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.

         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 Guarantor, it is requested that the Company sign the form of acceptance on a
copy hereof and mail or deliver a signed copy hereof to the undersigned at its
address set forth below. This will become a binding contract between the
