APACHE FINANCE PTY LTD

DEBT SECURITIES
 
IRREVOCABLY AND UNCONDITIONALLY GUARANTEED BY
APACHE CORPORATION
 
Apache Finance Pty Ltd, a proprietary company with limited liability organized
under the laws of the Australian Capital Territory, Australia (the "Issuer"),
and a wholly-owned indirect subsidiary of Apache Corporation (the "Company" or
"Apache"), intends from time to time to issue senior unsecured debt securities
("Debt Securities") in one or more series, at an aggregate initial offering
price not to exceed $300,000,000, at prices and on terms to be determined at or
prior to the time of sale. The specific designation, aggregate principal amount,
maturity, interest rate, method of distribution, and any prepayment or other
variable terms with regard to the Debt Securities in respect of which this
Prospectus is delivered will be, to the extent not set forth herein, set forth
in an accompanying Prospectus Supplement.
 
The Debt Securities will be irrevocably and unconditionally guaranteed (the
"Guarantees") by the Company (in such capacity, the "Guarantor"), and the
Guarantees will rank on a parity with all unsecured and unsubordinated
indebtedness of the Company.
 
Unless otherwise specified herein or in the applicable Prospectus Supplement,
the Debt Securities will be issued in fully registered book-entry form and will
be registered in the name of The Depository Trust Company, as depository
("DTC"), or its nominee. Interests in the Debt Securities will be shown on, and
transfers thereof will be effected only through, records maintained by DTC and
its participants. Debt Securities issued in book-entry form will not be issuable
as certificated securities except as specified herein or in the applicable
Prospectus Supplement. See "DTC Book-Entry-Only System." Payment of the
principal of, and premium, if any, and interest on the Debt Securities will be
made to DTC if and so long as DTC or its nominee is the registered owner of the
Debt Securities. The disbursement of such payments to beneficial owners of the
Debt Securities ("Beneficial Owners") will be the responsibility of the DTC
Participants and the Indirect Participants, all as defined and more fully
described in this Prospectus under the caption "DTC Book-Entry-Only System."
 
The applicable Prospectus Supplement will contain information, where applicable
and to the extent not set forth herein, concerning certain United States federal
income tax considerations relating to the Debt Securities covered by such
Prospectus Supplement.
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.
 
The Debt Securities may be sold directly by the Issuer to one or more
institutional purchasers, through agents designated from time to time, through
dealers or underwriters, or through any combination of the above. If any agents
of the Issuer, the Company or any underwriters are involved in the sale of the
Debt Securities, the names of such agents or underwriters and any applicable
commissions or discounts will be set forth in the Prospectus Supplement. See
"Plan of Distribution" for indemnification arrangements which the Issuer and the
Company are prepared to make available to underwriters and agents for the sale
of the Debt Securities.
 
The date of this Prospectus is             , 1997.

     IN CONNECTION WITH THIS OFFERING, THE UNDERWRITERS MAY OVER-ALLOT OR EFFECT
TRANSACTIONS WHICH STABILIZE OR MAINTAIN THE MARKET PRICE OF THE DEBT SECURITIES
OFFERED HEREBY AT A LEVEL ABOVE THAT WHICH MIGHT OTHERWISE PREVAIL IN THE OPEN
MARKET. SUCH TRANSACTIONS MAY BE EFFECTED IN THE OVER-THE-COUNTER MARKET OR
OTHERWISE. SUCH STABILIZING, IF COMMENCED, MAY BE DISCONTINUED AT ANY TIME.
 
     Neither the Issuer nor the Company has authorized, or taken any action to
cause, the issue or distribution in the Commonwealth of Australia, any of its
States, territories or possessions or any political subdivision thereof
("Australia"), or to any resident of Australia, of this Prospectus or any other
document inviting applications or offers to subscribe for or buy the Debt
Securities offered hereby or offering such Debt Securities for subscription or
purchase and, accordingly, neither this Prospectus (whether in draft or
definitive form) nor any such other document may be issued or distributed in
Australia or to any resident of Australia.
 
     No prospectus in relation to the Debt Securities has been lodged with or
registered by the Australian Securities Commission. In connection with the
distribution of the Debt Securities, each underwriter or agent in respect of
each series of Debt Securities will represent and agree that it: (a) has not
(directly or indirectly) offered for subscription or purchase or issued
invitations to subscribe for or buy nor has it sold any Debt Securities; (b)
will not (directly or indirectly) offer for subscription or purchase or issue
invitations to subscribe for or buy or sell any Debt Securities; and (c) has not
distributed and will not distribute any draft or definitive offering memorandum,
advertisement or other offering material, in each case in Australia or to any
resident of Australia (including corporations and other entities organized under
the laws of Australia but not including a permanent establishment of such
corporations or other entities located outside Australia).
 
     Apache Finance Pty Ltd is an Australian proprietary company with limited
liability. Some of its directors and executive officers, and the experts named
herein reside outside the United States (principally in Australia). All or a
substantial portion of the assets of these persons and of Apache Finance Pty Ltd
are located outside the United States. As a result, it may not be possible for
investors to effect service of process within the United States upon such
persons or to enforce against such persons or Apache Finance Pty Ltd judgments
obtained in United States courts predicated upon the civil liability provisions
of the federal securities laws of the United States. Apache Finance Pty Ltd has
been advised by its Australian counsel, Arthur Robinson & Hedderwicks, that
there is doubt as to the enforceability in the Commonwealth of Australia, in
original actions or in actions for enforcement of judgments of United States
courts, of civil liabilities predicated upon the federal securities laws of the
United States. Apache Finance Pty Ltd will appoint CT Corporation System as
authorized agent upon which process may be served in any action arising out of
or based upon the Indenture hereinafter described or the Debt Securities or the
Guarantees which may be instituted in any federal or state court having subject
matter jurisdiction in the Borough of Manhattan, The City of New York, New York.
See "Description of Debt Securities and Guarantees."
 
     Neither any associate (as defined in Division 16F of the Income Tax
Assessment Act 1936 of the Commonwealth of Australia (the "Tax Act") (but on the
basis that subparagraphs 159GZC(1)(a)(ii), (1)(b)(i) and (1)(d)(i) of the Tax
Act do not apply) of the Issuer (an "Associate") nor any resident of Australia
may (directly or indirectly) acquire any Debt Securities or any interest in or
right in respect of the Debt Securities (other than such a person who acquires
Debt Securities or such interest or right in the capacity of a dealer in
relation to the placement of the Debt Securities, interest or right).
 
     Each person who so acquires any Debt Securities or such interest or right
will be deemed to have warranted in favor of the Issuer that the person is
neither an Associate nor a resident of Australia. Any Associate who so acquires
any Debt Securities or any interest in or right in respect of the Debt
Securities may be subject to Australian interest withholding tax and, if so,
will not be entitled to receive any payment of Additional Amounts (as defined
herein) from the Issuer or the Guarantor.
 
     There are currently no Australian exchange controls which restrict the
payment of interest or Additional Amounts (as defined herein), or repayment of
principal to holders of the Debt Securities who are not residents of Australia,
provided they are not nationals of or connected with Iraq or Libya. The
authority of the Reserve Bank of Australia is required for certain payments to
the government of Iraq, the government of or the authorities in Libya, or the
authorities in the former Federal Republic of Yugoslavia (Serbia and Montenegro)
or their respective agencies or nationals.

the SEC for an order of the SEC exempting the Issuer from the reporting
requirements of the Exchange Act. If such order is granted, or the SEC otherwise
grants relief to the Issuer from such reporting requirements, the Issuer will
not be subject to the informational requirements of the Exchange Act. Subject to
SEC relief, the Company also does not intend to include in its consolidated
financial statements any separate financial information with respect to the
Issuer. In addition, in view of the Guarantees, the Issuer does not intend to
furnish to holders of Debt Securities separate financial statements of the
Issuer or other reports.

                                   THE ISSUER
 
     Apache Finance Pty Ltd is a proprietary company with limited liability
organized in October 1997 under the laws of the Australian Capital Territory,
Australia. Apache Finance Pty Ltd is an indirect wholly-owned subsidiary of the
Company. The purpose of Apache Finance Pty Ltd is to undertake borrowings on
behalf of the Company and certain other subsidiaries of the Company and to
advance the proceeds of such borrowings to the Company or certain of its other
subsidiaries of the Company.
 
                                USE OF PROCEEDS
 
     Unless otherwise specified in the applicable Prospectus Supplement, the net
proceeds from the sale of the Debt Securities will be used to refinance
outstanding indebtedness and for other general corporate purposes. To the extent
proceeds are used to refinance outstanding indebtedness, certain terms of the
indebtedness being refinanced will be set forth in the applicable Prospectus
Supplement.
 
                       RATIO OF EARNINGS TO FIXED CHARGES
 
     The Company's ratios of earnings to fixed charges were as follows for the
respective periods indicated:

     The Company's ratios of earnings to fixed charges were computed based on:
(A) consolidated income or losses from continuing operations before income taxes
and fixed charges (excluding interest capitalized); and (B) consolidated fixed
charges, which consist of interest on indebtedness (including amounts
capitalized), amortization of debt discount and expense and the estimated
portion of rental expense attributable to interest. Earnings were inadequate to
cover fixed charges by $14.8 million for 1992, due to write downs of the
carrying value of the U.S. and Canadian oil and gas properties of DEK Energy
Company ("DEKALB"), formerly known as DEKALB Energy Company, and losses incurred
on the divestiture of certain of DEKALB's U.S. assets.

                 DESCRIPTION OF DEBT SECURITIES AND GUARANTEES
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
Debt Securities and the Guarantees will be issued under an indenture (the
"Indenture") entered into between the Issuer, the Company and The Chase
Manhattan Bank, as trustee (the "Trustee"). The Company will irrevocably and
unconditionally guarantee payments of principal, interest and Additional
Amounts, if any, on the Debt Securities. The Debt Securities to be offered by
this Prospectus are limited to an aggregate initial offering price not to exceed
$300,000,000. However, the Indenture does not limit the amount of Debt
Securities which can be issued thereunder and provides that additional Debt
Securities of any series may be issued thereunder up to the aggregate principal
amount which may be authorized from time to time by the Issuer and the Company.
Unless otherwise indicated herein or in the applicable Prospectus Supplement,
the Debt Securities will be issued in denominations of $100,000 and integral
multiples of $1,000 in excess thereof.
 
     The maturity date, interest payment dates, and rate of interest of the Debt
Securities will be as set forth in the Prospectus Supplement applicable thereto.
Subject to certain exceptions therein set forth, the Indenture provides for the
payment of interest on any interest payment date only to persons in whose names
the Debt Securities are registered on the regular record date, which is the last
day of the respective calendar months preceding the month in which an interest
payment is due (whether or not a business day).
 
     A copy of the Indenture is an exhibit to the Registration Statement of
which this Prospectus is a part. The information herein includes a summary of
certain provisions of the Indenture and does not purport to be complete and is
subject to, and is qualified in its entirety by reference to, all provisions of
the Indenture including the definition therein of certain terms. The following
summaries set forth certain general terms and provisions of the Debt Securities
to which any Prospectus Supplement may relate. The particular terms of the Debt
Securities offered by any Prospectus Supplement and the extent, if any, to which
such general provisions may apply to the Debt Securities so offered will, to the
extent not described herein, be described in the Prospectus Supplement relating
to such Debt Securities.

modification to the definition of such terms contained in the Indenture as
originally executed) in respect of any tax, assessment or governmental charge
and, if so, whether the Issuer will have the option to redeem such Debt
Securities rather than pay such Additional Amounts (and the terms of any such
option); (xiii) any deletions from, modifications of or additions to the Events
of Default or covenants of the Issuer with respect to any of such Debt

at the same rate or mature on the same date.
 
     If any of the Debt Securities are sold for foreign currencies or foreign
currency units or if the principal of, or premium, if any, or interest, if any,
on any series of Debt Securities is payable in foreign currencies or foreign
currency units, the restrictions, elections, tax consequences, specific terms
and other information with respect to such Debt Securities and such foreign
currencies or foreign currency units will be set forth in the applicable
Prospectus Supplement.
 
     Other than as described below under "Limitation on Liens" and "Issuer's
Obligation to Purchase Debt Securities on Change in Control," the Indenture does
not contain any provision that would limit the ability of the Company or the
Issuer to incur indebtedness or that would afford holders of Debt Securities
protection in the event of a decline in the credit quality of the Company or the
Issuer or a takeover, recapitalization or highly leveraged or similar
transaction involving the Company or the Issuer . Reference is made to the
Prospectus Supplement relating to the particular series of Debt Securities
offered thereby, to the extent not otherwise described herein, for any
information with respect to any deletions from, modifications of or additions to
the Events of Default described below or covenants of the Company and the Issuer
contained in the Indenture, including any addition of a covenant or other
provision providing event risk or similar protection.
 
  Guarantees
 
     The Company will irrevocably and unconditionally guarantee to each holder
of a Debt Security issued by the Issuer and authenticated and delivered by the
Trustee the due and punctual payment of the principal of, any premium, and
interest on, such Debt Security, when and as the same shall become due and
payable, whether at maturity, upon acceleration, by call for redemption or
otherwise in accordance with the terms of the Debt Securities and of the
Indenture. The Company has (a) agreed that its obligations under the Guarantees
in the event of an Event of Default will be as if it were principal obligor and
not merely surety, and will be enforceable irrespective of any invalidity,
irregularity or unenforceability of any series of the Debt Securities or the
Indenture or any supplement thereto and (b) waived its right to require the
Trustee or the holders to pursue or exhaust its legal or equitable remedies
against the Issuer prior to exercising its rights under the Guarantees.
 
                                        7
<PAGE>   9
 
  Ranking
 
     The Guarantees will be unsecured obligations of the Company, and will rank
on a parity with all other unsecured and unsubordinated indebtedness of the
Company. The Debt Securities issued by the Issuer will be unsecured obligations
of the Issuer, and will rank on a parity with all other unsecured and
unsubordinated indebtedness of the Issuer.
 
     Dividend and other distributions to the Company from its various
subsidiaries may be subject to certain statutory, contractual and other
restrictions (including, without limitation, exchange controls that may be
applicable to foreign subsidiaries). The rights of any creditors of the Company
to participate in the assets of any subsidiary upon such subsidiary's
liquidation or recapitalization will be subject to the prior claims of the
subsidiary's creditors, except to the extent that the Company may itself be a
creditor with recognized claims against such subsidiary. The claims of holders
under the Debt Securities or the Guarantees will be effectively subordinated to
the claims of creditors of the Company's subsidiaries. The Indenture does not
restrict the amount of indebtedness that may be incurred by the Issuer, the
Company or its other subsidiaries.
 
  Interest Rates
 
     The Debt Securities will earn interest at the fixed or floating rate for
the period of time specified in the applicable Prospectus Supplement.
 
     If the Debt Securities earn interest at a floating rate, the applicable
Prospectus Supplement shall state the Interest Rate Basis or Bases (including
(a) the applicable Spread, if any, and/or (b) multiplied by the applicable
Spread Multiplier, if any), the Interest Payment Period and Dates, the Index
Maturity and the Maximum Interest Rate and/or Minimum Interest Rate, if any, as
such terms are defined below. If one or more of the applicable Interest Rate
Bases is LIBOR, the Prospectus Supplement must also specify the Index Currency
and Designated LIBOR Page, as such terms are defined below. Unless otherwise
specified in the applicable Prospectus Supplement, the Debt Securities shall
bear interest on the basis of a 360-day year consisting of twelve 30-day months.
 
     The "Spread" is the number of basis points to be added to or subtracted
from the related Interest Rate Basis or Bases applicable to each respective Debt
Security. The "Spread Multiplier" is the percentage of the related Interest Rate
Basis or Bases by which such Interest Rate Basis or Bases will be multiplied to
determine the applicable interest rate. The "Index Maturity" is the period to
maturity of the instrument or obligation with respect to which the related
Interest Rate Basis or Bases will be calculated.
 
     Unless otherwise specified in the Prospectus Supplement, the Interest Rate
Basis may, as described below, include (i) the Commercial Paper Rate, (ii)
LIBOR, (iii) the Treasury Rate, or (iv) such other Interest Rate Basis or
interest rate formula as may be specified in the applicable Prospectus
Supplement.
 
     The applicable Prospectus Supplement will specify whether the floating rate
of interest will be reset daily, weekly, monthly, quarterly, semiannually or
annually or on such other specified basis (each, an "Interest Reset Period") and
the dates on which such rate of interest will be reset (each, an "Interest Reset
Date"). Unless otherwise specified in the applicable Prospectus Supplement, the
Interest Reset Dates will be, in the case of a floating interest rate which
resets: (i) daily, each Business Day; (ii) weekly, the Wednesday of each week
(unless the Treasury Rate is an applicable Interest Rate Basis, in which case
the Tuesday of each week except as described below); (iii) monthly, the third
Wednesday of each month; (iv) quarterly, the third Wednesday of March, June,
September and December of each year, (v) semiannually, the third Wednesday of
the two months specified in the applicable Prospectus Supplement; and (vi)
annually, the third Wednesday of the month specified in the applicable
Prospectus Supplement. If any Interest Reset Date would otherwise be a day that
is not a Business Day, such Interest Reset Date will be postponed to the next
succeeding Business Day, unless LIBOR is an applicable Interest Rate Basis and
such Business Day falls in the next succeeding calendar month, in which case
such Interest Reset Date will be the immediately preceding Business Day. In
addition, if the Treasury Rate is an applicable Interest Rate Basis and the
Interest Determination Date would otherwise fall on an
 
                                        8
<PAGE>   10
 
Interest Reset Date, then such Interest Reset Date will be postponed to the next
succeeding Business Day.
 
     The interest rate applicable to each Interest Reset Period commencing on
the related Interest Reset Date will be the rate determined as of the applicable
Interest Determination Date on or prior to the Calculation Date (as hereinafter
defined). The "Interest Determination Date" (i) with respect to the Commercial
Paper Rate will be the second Business Day immediately preceding the applicable
Interest Reset Date; (ii) with respect to LIBOR will be the second London
Business Day immediately preceding the applicable Interest Reset Date, unless
the Index Currency is British pounds sterling, in which case the "Interest
Determination Date" will be the applicable Interest Reset Date; and (iii) with
respect to the Treasury Rate will be the day that Treasury Bills (as hereinafter
defined) are auctioned during or for the week in which the applicable Interest
Reset Date falls (Treasury Bills being normally sold at an auction held on
Monday of each week, unless that day is a legal holiday, in which case the
auction is normally held on the following Tuesday, except that such auction may
be held on the preceding Friday); provided, however, that if an auction is held
on the Friday of the week preceding the applicable Interest Reset Date, the
Interest Determination Date will be such preceding Friday. The "Interest
Determination Date" pertaining to a floating interest rate which is determined
by reference to two or more Interest Rate Bases will be the most recent Business
Day which is at least two Business Days prior to the applicable Interest Reset
Date on which each Interest Rate Basis is determinable. Each Interest Rate Basis
will be determined as of such date, and the applicable interest rate will take
effect on the applicable Interest Reset Date.
 
     Either or both of the following may also apply to the floating interest
rate on Debt Securities: (i) a Maximum Interest Rate, or ceiling, that may
accrue during any Interest Reset Period, and (ii) a Minimum Interest Rate, or
floor, that may accrue during any Interest Reset Period. In addition to any
Maximum Interest Rate that may apply, the interest rate on any Debt Securities
will in no event be higher than the maximum rate permitted by New York law, as
the same may be modified by United States laws of general application.
 
     Except as provided below or in the applicable Prospectus Supplement,
interest will be payable, in the case of floating interest rates which reset:
(i) daily, weekly or monthly, on the third Wednesday of each month or on the
third Wednesday of March, June, September and December of each year, as
specified in the applicable Prospectus Supplement; (ii) quarterly, on the third
Wednesday of March, June, September and December of each year, (iii)
semiannually, on the third Wednesday of the two months of each year specified in
the applicable Prospectus Supplement; and (iv) annually, on the third Wednesday
of the month of each year specified in the applicable Prospectus Supplement. If
any Interest Payment Date for the payment of interest at a floating rate would
otherwise be a day that is not a Business Day, such Interest Payment Date will
be postponed to the next succeeding Business Day, except that if LIBOR is an
applicable Interest Rate Basis and such Business Day falls in the next
succeeding calendar month, such Interest Payment Date will be the immediately
preceding Business Day.
 
     All percentages resulting from any calculation of floating interest rates
will be rounded to the nearest one hundred-thousandth of a percentage point,
with five one-millionths of a percentage point rounded upwards (e.g., 9.876545
percent (or .09876545) would be rounded to 9.87655 percent (or .0987655)), and
all amounts used in or resulting from such calculation will be rounded, in the
case of United States dollars, to the nearest cent or, in the case of a foreign
currency or composite currency, to the nearest unit (with one-half cent or unit
being rounded upwards).
 
     Accrued floating rate interest will be calculated by multiplying the
principal amount of the Debt Securities to which it relates by an accrued
interest factor. Such accrued interest factor will be computed by adding the
interest factor calculated for each day in the applicable Interest Reset Period.
Unless otherwise specified in the applicable Prospectus Supplement, the interest
factor for each such day will be computed by dividing the interest rate
applicable to such day by 360, if an applicable Interest Rate Basis is the
Commercial Paper Rate or LIBOR, or by the actual number of days in the year if
an applicable
 
                                        9
<PAGE>   11
 
Interest Rate Basis is the Treasury Rate. Unless otherwise specified in the
applicable Prospectus Supplement, if the floating interest rate is calculated
with reference to two or more Interest Rate Bases, the interest factor will be
calculated in each period in the same manner as if only one of the applicable
Interest Rate Bases applied as specified in the applicable Prospectus
Supplement.
 
     Unless otherwise specified in the applicable Prospectus Supplement, The
Chase Manhattan Bank will be the "Calculation Agent." Upon request of the
Beneficial Owner of any Debt Securities, the Calculation Agent will disclose the
interest rate then in effect and, if determined, the interest rate that will
become effective as a result of a determination made for the next succeeding
Interest Reset Date with respect to such Debt Securities. Unless otherwise
specified in the applicable Prospectus Supplement, the "Calculation Date," if
applicable, pertaining to any Interest Determination Date will be the earlier of
(i) the tenth calendar day after such Interest Determination Date or, if such
day is not a Business Day, the next succeeding Business Day or (ii) the Business
Day immediately preceding the applicable Interest Payment Date or the Maturity
Date, as the case may be.
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
Calculation Agent shall determine each Interest Rate Basis in accordance with
the following provisions.
 
     Commercial Paper Rate. Unless otherwise specified in the applicable
Prospectus Supplement, "Commercial Paper Rate" means, with respect to any
Interest Determination Date for which the interest rate is determined with
reference to the Commercial Paper Rate (a "Commercial Paper Rate Interest
Determination Date"), the Money Market Yield (as hereinafter defined) on such
date of the rate for commercial paper having the Index Maturity specified in the
applicable Prospectus Supplement as published in H.15(519) under the heading
"Commercial Paper." In the event that such rate is not published by 3:00 p.m.,
New York City time, on the related Calculation Date, then the Commercial Paper
Rate on such Commercial Paper Rate Interest Determination Date will be the Money
Market Yield of the rate for commercial paper having the Index Maturity
specified in the applicable Prospectus Supplement as published in Composite
Quotations under the heading "Commercial Paper" (with an Index Maturity of one
month or three months being deemed to be equivalent to an Index Maturity of 30
days or 90 days, respectively). If such rate is not yet published in either
H.15(519) or Composite Quotations by 3:00 p.m., New York City time, on the
related Calculation Date, then the Commercial Paper Rate on such Commercial
Paper Rate Interest Determination Date will be calculated by the Calculation
Agent and will be the Money Market Yield of the arithmetic mean of the offered
rates at approximately 11:00, New York City time, on such Commercial Paper Rate
Interest Determination Date of three leading dealers of commercial paper in New
York, New York selected by the Calculation Agent, after consultation with the
Issuer, for commercial paper having the Index Maturity specified in the
applicable Prospectus Supplement placed for an industrial issuer whose bond
rating is "AA," or the equivalent, from a nationally recognized statistical
rating organization; provided, however, that if the dealers so selected by the
Calculation Agent are not quoting as mentioned in this sentence, the Commercial
Paper Rate determined as of such Commercial Paper Rate Interest Determination
Date will be the Commercial Paper Rate in effect on such Commercial Paper Rate
Interest Determination Date.
 
     "Money Market Yield" means a yield (expressed as a percentage) calculated
in accordance with the following formula:
 
<TABLE>
<S>                    <C>             <C>
Money Market Yield =         D x 360   x 100
                       -------------
                       360 - (D x M)
</TABLE>
 
where "D" refers to the applicable per annum rate for commercial paper quoted on
a bank discount basis and expressed as a decimal, and "M" refers to the actual
number of days in the Interest Period for which interest is being calculated.
 
                                       10
<PAGE>   12
 
     LIBOR. Unless otherwise specified in the applicable Prospectus Supplement,
"LIBOR" means the rate determined in accordance with the following provisions:
 
          (i) With respect to any Interest Determination Date for which the
     interest rate is determined with reference to LIBOR (a "LIBOR Interest
     Determination Date"), LIBOR will be either: (a) if "LIBOR Reuters" is
     specified in the applicable Prospectus Supplement, the arithmetic mean of
     the offered rates (unless the Designated LIBOR Page by its terms provides
     only for a single rate, in which case such single rate shall be used) for
     deposits in the Index Currency having the Index Maturity specified in such
     Prospectus Supplement, commencing on the applicable Interest Reset Date,
     that appear (or, if only a single rate is required as aforesaid, appears)
     on the Designated LIBOR Page as of 11:00 a.m., London time, on such LIBOR
     Interest Determination Date, or (b) if "LIBOR Telerate" is specified in the
     applicable Prospectus Supplement or if neither "LIBOR Reuters" nor "LIBOR
     Telerate" is specified in the applicable Prospectus Supplement as the
     method for calculating LIBOR, the rate for deposits in the Index Currency
     having the Index Maturity specified in such Prospectus Supplement,
     commencing on such Interest Reset Date, that appears on the Designated
     LIBOR Page as of 11:00 a.m., London time, on such LIBOR Interest
     Determination Date. If fewer than two such offered rates appear, or if no
     such rate appears, as applicable, LIBOR on such LIBOR Interest
     Determination Date will be determined in accordance with the provisions
     described in clause (ii) below.
 
          (ii) With respect to a LIBOR Interest Determination Date on which
     fewer than two offered rates appear, or no rate appears, as the case may
     be, on the Designated LIBOR Page as specified in clause (i) above, the
     Calculation Agent will request the principal London offices of each of four
     major reference banks in the London interbank market, as selected by the
     Calculation Agent, after consultation with the Issuer, to provide the
     Calculation Agent with its offered quotation for deposits in the Index
     Currency for the period of the Index Maturity specified in the applicable
     Prospectus Supplement, commencing on the applicable Interest Reset Date, to
     prime banks in the London interbank market at approximately 11:00 a.m.,
     London time, on such LIBOR Interest Determination Date and in a principal
     amount that is representative for a single transaction in such Index
     Currency in such market at such time. If at least two such quotations are
     so provided, then LIBOR on such LIBOR Interest Determination Date will be
     the arithmetic mean of such quotations. If fewer than two such quotations
     are so provided, then LIBOR on such LIBOR Interest Determination Date will
     be the arithmetic mean of the rates quoted at approximately 11:00 a.m., in
     the applicable Principal Financial Center, on such LIBOR Interest
     Determination Date by three major banks in such Principal Financial Center
     selected by the Calculation Agent, after consultation with the Issuer, for
     loans in the Index Currency to leading European banks, having the Index
     Maturity specified in the applicable Prospectus Supplement and in a
     principal amount that is representative for a single transaction in such
     Index Currency in such market at such time; provided, however, that if the
     banks so selected by the Calculation Agent are not quoting as mentioned in
     this sentence, LIBOR determined as of such LIBOR Interest Determination
     Date will be LIBOR in effect on such LIBOR Interest Determination Date.
 
          (iii) "Index Currency" means the currency or composite currency
     specified in the applicable Prospectus Supplement as to which LIBOR shall
     be calculated. If no such currency or composite currency is specified in
     the applicable Prospectus Supplement, the Index Currency shall be United
     States dollars.
 
     "Principal Financial Center" means the capital city of the country issuing
the Index Currency, except that with respect to United States dollars,
Australian dollars, Deutsche marks, Dutch guilders, Italian lire, Swiss francs
and ECUs, the Principal Financial Center shall be New York City, Sydney,
Frankfurt, Amsterdam, Milan, Zurich and Luxembourg, respectively.
 
     "Designated LIBOR Page" means (a) if "LIBOR Reuters" is specified in the
applicable Prospectus Supplement, the display on the Reuters Monitor Money Rates
Service (or any successor service) for the purpose of displaying the London
interbank rates of major banks for the applicable Index Currency, or
 
                                       11
<PAGE>   13
 
(b) if "LIBOR Telerate" is specified in the applicable Prospectus Supplement or
neither "LIBOR Reuters" nor "LIBOR Telerate" is specified in the applicable
Prospectus Supplement as the method for calculating LIBOR, the display on the
Dow Jones Telerate Service (or any successor service) for the purpose of
displaying the London interbank rates of major banks for the applicable Index
Currency.
 
     Treasury Rate. Unless otherwise specified in the applicable Prospectus
Supplement, "Treasury Rate" means, with respect to any Interest Determination
Date for which the interest rate is determined by reference to the Treasury Rate
(a "Treasury Rate Interest Determination Date"), the rate from the auction held
on such Treasury Rate Interest Determination Date (the "Auction") of direct
obligations of the United States ("Treasury Bills") having the Index Maturity
specified in the applicable Prospectus Supplement, as such rate is published in
H.15(519) under the heading "Treasury Bills -- auction average (investment)" or,
if not published by 3:00 p.m., New York City time, on the related Calculation
Date, the auction average rate of such Treasury Bills (expressed as a bond
equivalent on the basis of a year of 365 or 366 days, as applicable, and applied
on a daily basis) as otherwise announced by the United States Department of the
Treasury. In the event that the results of the Auction of Treasury Bills having
the Index Maturity specified in the applicable Prospectus Supplement are not
reported as provided by 3:00 p.m., New York City time, on the related
Calculation Date, or if no such Auction is held, then the Treasury Rate will be
calculated by the Calculation Agent, after consultation with the Issuer, and
will be a yield to maturity (expressed as a bond equivalent on the basis of a
year of 365 or 366 days, as applicable, and applied on a daily basis) of the
arithmetic mean of the secondary market bid rates, as of approximately 3:30
p.m., New York City time, on such Treasury Rate Interest Determination Date, of
three leading primary United States government securities dealers selected by
the Calculation Agent, after consultation with the Issuer, for the issue of
Treasury Bills with a remaining maturity closest to the Index Maturity specified
in the applicable Prospectus Supplement; provided, however, that if the dealers
so selected by the Calculation Agent are not quoting as mentioned in this
sentence, the Treasury Rate determined as of such Treasury Rate Interest
Determination Date will be the Treasury Rate in effect on such Treasury Rate
Interest Determination Date.
 
  Discount, Series, Maturities, Registration, and Payment
 
     The Debt Securities may be sold at a substantial discount below their
stated principal amount, bearing no interest or interest at a rate that at the
time of issuance is below market rates. See "Certain Tax
Considerations -- United States Federal Income Tax Considerations" and "Certain
Tax Considerations -- Australian Tax Considerations", respectively, herein.
United States federal income tax consequences and special considerations
applicable to any such series may also be described in the Prospectus Supplement
relating thereto.
 
     The Debt Securities may be issued in one or more series with the same or
various maturities. (Section 301) Debt Securities may be issued solely in fully
registered form without coupons ("Registered Securities"), solely in bearer form
with or without coupons ("Bearer Securities"), or as both Registered Securities
and Bearer Securities. (Section 301) Registered Securities may be exchangeable,
upon surrender, for other Debt Securities of the same series, registered in the
same name, for a like aggregate principal amount in authorized denominations and
will be transferable at any time or from time to time at the aforementioned
office. No service charge will be made to the holder for any such exchange or
transfer, except for any tax or governmental charge incidental thereto. If Debt
Securities of any series are issued as Bearer Securities, the applicable
Prospectus Supplement will contain any restrictions applicable to the offer,
sale or delivery of Bearer Securities and the terms upon which Bearer Securities
of the series may be exchanged for Registered Securities of the series and, if
permitted by applicable laws and regulations, the terms upon which Registered
Securities of the series may be exchanged for Bearer Securities of the series,
whether such Debt Securities are to be issuable in permanent global form with or
without coupons and, if so, whether beneficial owners of interests in any such
permanent global security may exchange such interests for Debt Securities of
such series and the circumstances under which any such exchanges may occur.

<PAGE>   14
 
     Unless otherwise specified in the applicable Prospectus Supplement,
principal and interest, if any, on the Debt Securities offered thereby are to be
payable at the office or agency of the Issuer and the Company maintained for
such purposes in the city where the principal corporate trust office of the
Trustee is located, and will initially be the principal corporate trust office
of the Trustee, provided that payment of interest, if any, may be made (subject
to collection) by check mailed to the persons in whose names the Debt Securities
are registered at the close of business on the day specified in the applicable
Prospectus Supplement.
 
  Form, Exchange, Registration and Transfer
 
     Debt Securities will be exchangeable for other Debt Securities of the same
series and of like tenor, of any authorized denominations and of a like
aggregate principal amount and Stated Maturity (as defined in the Indenture).
Registered Securities may be presented for registration of transfer (with the
form of transfer endorsed thereon duly executed) at the office of the Trustee or
at the corporate trust office of any transfer agent designated by the Issuer or
the Company for such purpose, without service charge and upon payment of any
taxes and other governmental charges as described in the Indenture. Such
transfer or exchange will be effected upon the books of the Trustee or such
transfer agent contingent upon such Trustee or transfer agent, as the case may
be, being satisfied with the documents of title and identity of the person
making the request. (Section 305)
 
     In the event of any redemption of Debt Securities, neither the Issuer nor
the Company shall be required to: (i) issue, register the transfer of or
exchange such Debt Securities during a period beginning at the opening of
business 15 days before any selection of such Debt Securities to be redeemed and
ending at the close of business on the day of mailing of the relevant notice of
redemption; or (ii) register the transfer of or exchange any such Debt Security,
or portion thereof, called for redemption, except the unredeemed portion of any
such Debt Security being redeemed in part. (Section 305)
 
  Limitation on Liens
 
     Nothing in the Indenture or the Debt Securities will in any way limit the
amount of indebtedness or securities (other than the Debt Securities) which may
be incurred or issued by the Company or any of its Subsidiaries (as defined in
the Indenture). The Indenture provides that neither the Issuer nor the Company
nor any Subsidiary will issue, assume or guarantee any notes, bonds, debentures
or other similar evidences of indebtedness for money borrowed secured by any
mortgage, lien, pledge, security interest or other encumbrance (defined in the
Indenture as "Liens") upon any of its property, subject to certain exceptions
set forth in the Indenture, without making effective provisions whereby any and
all Debt Securities then outstanding shall be secured by a Lien equally and
ratably with any and all other obligations thereby secured. Such restrictions
will not, however, apply to (a) Liens existing on the date of the Indenture or
provided for under the terms of agreements existing on the date thereof; (b)
Liens on property to secure (i) all or part of the cost of exploring, producing,
gathering, processing, marketing, drilling or developing such property, or to
secure indebtedness incurred to provide funds therefor; or (ii) indebtedness
incurred to finance all or part of the cost of acquiring, constructing,
altering, improving or repairing any such property or assets, or securing
indebtedness incurred to provide funds therefor; (c) Liens which secure only
indebtedness owing by a Subsidiary to the Issuer or the Company, or to one or
more Subsidiaries, or the Company and one or more Subsidiaries; (d) Liens on the
property of any corporation or other entity existing at the time such
corporation or entity becomes a Subsidiary; (e) Liens on any property to secure
indebtedness incurred in connection with the construction, installation or
financing of pollution control or abatement facilities or other forms of
industrial revenue bond financing or indebtedness issued or guaranteed by the
United States, any state or any department, agency or instrumentality of either
or indebtedness issued to or guaranteed for the benefit of a foreign government,
any state or any department, agency or instrumentality of either or an
international finance agency or any division or department thereof, including
the World Bank, the International Finance Corp. and the Multilateral Investment
Guarantee Agency; (f) any extension, renewal or replacement (or successive
extensions, renewals or replacements) of any Lien referred to in the foregoing
clauses (a) through
 
                                       13
<PAGE>   15
 
(e) existing on the date of the Indenture; (g) certain Liens incurred in the
ordinary course of business of the Company or (h) Liens which secure Limited
Recourse Indebtedness (as defined in the Indenture). The following types of
transactions, among others, shall not be deemed to create indebtedness secured
by Liens: (i) the sale or other transfer of crude oil, natural gas or other
petroleum hydrocarbons in place for a period of time until, or in an amount such
that, the transferee will realize therefrom a specified amount (however
determined) of money or such crude oil, natural gas or other petroleum
hydrocarbons, or the sale or other transfer of any other interest in property of
the character commonly referred to as a production payment, overriding royalty,
forward sale or similar interest and (ii) Liens required by any contract or
statute in order to permit the Issuer, the Company or a Subsidiary to perform
any contract or subcontract made by it with or at the request of the United
States government or any foreign government or international finance agency, any
state or any department thereof, or any agency or instrumentality of either, or
to secure partial, progress, advance or other payments to the Company or any
Subsidiary by any such entity pursuant to the provisions of any contract or
statute. (Section 1005)
 
  Limitation on Sale/Leaseback Transactions
 
     The Indenture provides that neither the Company nor any Subsidiary will
enter into any arrangement with any person (other than the Company or a
Subsidiary) providing for the leasing to the Company or a Subsidiary for a
period of more than three years of any property which has been, or is to be,
sold or transferred by the Company or such Subsidiary to such person or to any
person (other than the Company or a Subsidiary) to which funds have been or are
to be advanced by such person on the security of the leased property unless
either (a) the Issuer, the Company or such Subsidiary would be entitled,
pursuant to the provisions described under "Limitation on Liens" above, to incur
indebtedness in a principal amount equal to or exceeding the value of such
sale/leaseback transaction, secured by a Lien on the property to be leased; (b)
since the date of the Indenture and within a period commencing six months prior
to the consummation of such arrangement and ending six months after the
consummation thereof, the Issuer, the Company or such Subsidiary has expended or
will expend for any property (including amounts expended for the acquisition,
exploration, drilling or development thereof, and for additions, alterations,
improvements and repairs thereto) an amount equal to all or a portion of the net
proceeds of such arrangement and the Issuer, the Company or such Subsidiary, as
the case may be, elects to designate such amount as a credit against such
arrangement (with any such amount not being so designated to be applied as set
forth in (c) below); or (c) the Issuer, the Company or any Subsidiary, during or
immediately after the expiration of the 12 months after the effective date of
such transaction, applies to the voluntary redemption, defeasance or retirement
of the Debt Securities and its other Senior Indebtedness (as defined in the
Indenture) an amount equal to the greater of the net proceeds of the sale or
transfer of the property leased in such transaction or the fair value, in the
opinion of the board of directors of the Issuer, the Company or the Subsidiary
of such property at the time of entering into such transaction (in either case
adjusted to reflect the remaining term of the lease and any amount utilized by
the Company as set forth in (b) above), less an amount equal to the principal
amount of Senior Indebtedness voluntarily retired by the Company within such
12-month period. (Section 1006)
 
  Exempted Indebtedness
 
     Notwithstanding the limitations on Liens and sale/leaseback transactions
outlined above, the Issuer, the Company or any other Subsidiary may create,
assume or suffer to exist Liens or enter into sale/leaseback transactions not
otherwise permitted as described above, provided that at the time of such event,
and after giving effect thereto, the sum of outstanding indebtedness for
borrowed money incurred after the date of the Indenture and secured by such
Liens plus the attributable debt in respect of such sale/leaseback transactions
entered into after the date of the Indenture does not exceed 10 percent of
Consolidated Net Worth (as defined in the Indenture) properly appearing on a
consolidated balance sheet of the Company. (Sections 1005 and 1006)
 
                                       14
<PAGE>   16
 
  Assignment
 
     The Indenture provides that for so long as any of the Debt Securities of
the Issuer are outstanding, the Issuer may assign its obligations under any
series of Debt Securities to any other Subsidiary (the "Subsidiary Assignee")
and such Subsidiary Assignee shall be treated as the Successor to the Issuer
with respect to such series of Debt Securities, provided that the conditions set
forth under "Consolidation, Merger and Sale of Assets" below that would apply to
the merger of the Issuer into such Subsidiary Assignee are satisfied. (Section
802)
 
  Events of Default
 
     Unless otherwise specified in the applicable Prospectus Supplement, any one
of the following events will constitute an Event of Default under the Indenture
with respect to the Debt Securities of any series: (a) failure to pay any
interest on any Debt Security of such series when due, continued for 30 days;
(b) failure to pay principal of (or premium, if any) on the Debt Securities of
such series when due and payable, either at maturity, upon redemption or, if
applicable, at 12:00 noon on the Business Day following the Change in Control
Purchase Date; (c) failure to perform, or breach of, any other covenant or
warranty of the Issuer or the Company in the Indenture or the Debt Securities
(other than a covenant or warranty included in the Indenture solely for the
benefit of a series of securities other than the Debt Securities), continued for
60 days after written notice as provided in the Indenture; (d) the acceleration
of any Indebtedness (as defined in the Indenture) of the Issuer, the Company or
any Subsidiary in excess of an aggregate of $25,000,000 in principal amount
under any event of default as defined in any mortgage, indenture or instrument
and such acceleration has not been rescinded or annulled within 30 days after
written notice as provided in the Indenture specifying such Event of Default and
requiring the Issuer and the Company to cause such acceleration to be rescinded
or annulled; (e) failure to pay, bond or otherwise discharge within 60 days of
entry, a judgment, court order or uninsured monetary damage award against the
Issuer, the Company or any other Subsidiary exceeding an aggregate of
$25,000,000 in principal amount which is not stayed on appeal or otherwise being
appropriately contested in good faith; (f) certain events of bankruptcy,
insolvency or reorganization involving the Issuer, the Company or any other
Subsidiary; and (g) any other Event of Default provided with respect to the Debt
Securities of that series. (Section 501)
 
     If an Event of Default with respect to the Debt Securities of any series
(other than an Event of Default described in (e) or (f) of the preceding
paragraph) occurs and is continuing, either the Trustee or the holders of at
least 25 percent in aggregate principal amount of the outstanding Debt
Securities of such series by notice as provided in the Indenture may declare the
principal amount of such Debt Securities to be due and payable immediately. At
any time after a declaration of acceleration has been made, but before a
judgment or decree for payment of money has been obtained by the Trustee, and
subject to applicable law and certain other provisions of the Indenture, the
holders of a majority in aggregate principal amount of the Debt Securities of
such series may, under certain circumstances, rescind and annul such
acceleration. An Event of Default described in (e) or (f) of the preceding
paragraph shall cause the principal amount and accrued interest (or such lesser
amount as provided for in the Debt Securities of such series) to become
immediately due and payable without any declaration or other act by the Trustee
or any holder. (Section 502)
 
     The Indenture provides that, within 90 days after the occurrence of any
Event of Default thereunder with respect to the Debt Securities of any series,
the Trustee shall transmit, in the manner set forth in the Indenture, notice of
such Event of Default to the holders of the Debt Securities of such series
unless such Event of Default has been cured or waived; provided, however, that
except in the case of a default in the payment of principal of, or premium, if
any, or interest, if any, or additional amounts, if any, on any Debt Security of
such series, the Trustee may withhold such notice if and so long as the board of
directors, the executive committee or a trust committee of directors or
Responsible Officers (as defined in the Indenture) of the Trustee have in good
faith determined that the withholding of such notice is in the interest of the
holders of Debt Securities of such series. (Section 602)
 
                                       15
<PAGE>   17
 
     If an Event of Default occurs and is continuing with respect to the Debt
Securities of any series, the Trustee may in its discretion proceed to protect
and enforce its rights and the rights of the holders of Debt Securities of such
series by all appropriate judicial proceedings. (Section 504)
 
     The Indenture provides that, subject to the duty of the Trustee during any
default to act with the required standard of care, the Trustee will be under no
obligation to exercise any of its rights or powers under the Indenture at the
request or direction of any of the holders of Debt Securities, unless such
holders shall have offered to the Trustee reasonable indemnity. (Section 601)
 
     Subject to such provisions for the indemnification of the Trustee, and
subject to applicable law and certain other provisions of the Indenture, the
holders of a majority in aggregate principal amount of the outstanding Debt
Securities of a series will have the right to direct the time, method and place
of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee, with respect to the Debt
Securities of such series. (Section 512)
 
  Assumption by the Company
 
     The Company may, at its option, assume the obligations of the Issuer as
obligor under any series of Debt Securities, provided that:
 
          (a) the Company shall expressly assume such obligations in an
     assumption agreement or supplemental indenture duly executed and delivered
     to the Trustee in form reasonably satisfactory to Trustee;
 
          (b) immediately after giving effect to such assumption, no Event of
     Default and no event which, after notice or lapse of time or both, would
     become an Event of Default, shall have occurred and be continuing; and
 
          (c) the Company shall expressly agree in an assumption agreement or
     supplemental indenture to immediately indemnify (pursuant to the procedure
     described below under "Indemnification Procedure") the holder of each Debt
     Security against (i) any tax, assessment or governmental charge imposed on
     such holder or required to be withheld or deducted from any payment to such
     holder (including any governmental charge or withholding tax attributable
     to the Company's indemnifying such holder) as a consequence of such
     assumption, and (ii) any costs or expenses of such assumption (except that
     if the Company delivers an opinion of an independent counsel or a tax
     consultant of recognized standing that the holders will not recognize
     income, gain or loss for United States federal income tax purposes as a
     result of such assumption, a holder will have such rights to
     indemnification only if and when gain for United States federal income tax
     purposes is actually imposed on such holder).
 
     Upon any such assumption, the Company shall succeed to, and be substituted
for, and may exercise any right and power of, the Issuer under such series of
Debt Securities and the Indenture with the same effect as if the Company had
been the Issuer thereof, and the Subsidiary shall be released from its liability
as obligor under such series of Debt Securities. (Section 804)
 
     See "Certain Tax Considerations -- United States Federal Income Tax
Considerations -- Taxation of Dispositions" for a discussion of certain
potential United States federal income tax consequences of an assumption of the
Debt Securities pursuant to this provision.
 
  Indemnification Procedure
 
     If a transaction described under "Consolidation, Merger and Sale of Assets"
or "Assumption by the Company" (an "Indemnifiable Transaction") should
constitute a taxable event for United States federal income tax purposes, the
Company or any Person (as defined in the Indenture), as the case may be, must
indemnify a holder of a Debt Security against any tax, assessment, or
governmental charge imposed on such holder or required to be withheld or
deducted from any payment to such holder (including any governmental charge or
withholding attributable to an indemnification payment made by
 
                                       16
<PAGE>   18
 
or on behalf of the Company or any Person) and any other tax costs or tax
expenses attributable to such Indemnifiable Transaction. In satisfying such
indemnification obligation, the Company or any such Person, as the case may be,
shall comply with the indemnification procedures below. (Section 805)
 
     Unless the Company or any such Person, as the case may be, delivers to the
Trustee by the date of an Indemnifiable Transaction (as defined in the
Indenture) an opinion of an independent counsel or a tax consultant of
recognized standing to the effect that such Indemnifiable Transaction will not
be a taxable event for United States federal income tax purposes, the Company or
any such Person, as the case may be, shall send to each holder on or prior to
the date of such Indemnifiable Transaction (a) notification explaining the
United States federal income tax consequences to each such holder of such
Indemnifiable Transaction and (b) an indemnification claim requesting (i)
information concerning each such holder's tax basis and holding period in a Debt
Security; (ii) a statement that the holder is not an entity that is exempt from
United States federal income tax as described in Section 501 of the Code, and
(iii) setting forth the address to which each such holder must remit such form.
If the Company or any such Person delivers such an Opinion, each holder will
have the indemnification rights described herein only if and when gain for
United States federal income tax purposes is actually imposed on such holder.
 
     When the Company or any Person, as the case may be, receives from a holder
an indemnification claim form, the Company or any such Person, as the case may,
shall within 15 business days remit to such holder a certified check in an
amount equal to the sum of (a) the product of any gain recognized as a result of
the Indemnifiable Transaction and the highest marginal tax rate in effect at the
time of such Indemnifiable Transaction (the "Indemnification Amount") and (b)
the product of the Indemnification Amount and such tax rate. For these purposes,
a holder's gain shall equal the amount by which the fair market value of a Debt
Security at the time of such Indemnifiable Transaction exceeds such holder's
adjusted tax basis in such Debt Security.
 
  Issuer's Obligation to Purchase Debt Securities on Change in Control
 
     Upon the occurrence of a "Change in Control" as defined in the Indenture,
the Issuer shall mail within 15 days of the occurrence of such Change in Control
written notice regarding such Change in Control to the Trustee of the Debt
Securities of each series and to every holder thereof, after which the Issuer
shall be obligated, at the election of each holder thereof, to purchase such
Debt Securities. Under the Indenture, a "Change in Control" is deemed to occur
upon (a) the occurrence of any event requiring the filing of any report under or
in response to Schedule 13D or 14D-1 pursuant to the Exchange Act disclosing
beneficial ownership of either (i) 50 percent or more of the Company's Common
Stock then outstanding, or (ii) 50 percent or more of the voting power of the
voting stock of the Company then outstanding, (b) the consummation of sale,
transfer, lease, or conveyance of the Company's properties and assets
substantially as an entirety to any Person or Persons who are not Subsidiaries
of the Company; and (c) the consummation of any consolidation of the Company
with or merger of the Company into any other Person in a transaction in which
either (i) the Company is not the sole surviving corporation or (ii) Common
Stock existing prior to such transaction is converted into cash, securities or
other property and those exchanging the Company's Common Stock do not receive
either (x) 75 percent or more of the survivor's common stock or (y) 75 percent
or more of the voting power of the survivor's voting stock, following the
consummation of such transaction. The notice to be sent to every Trustee and
holder upon a Change in Control shall, in addition, be published at least once
in an Authorized Newspaper (as defined in the Indenture) and shall state (a) the
event causing The Change in Control and the date thereof, (b) the date by which
notice of such Change in Control is required by the Indenture to be given, (c)
the date (which date shall be 35 business days after the occurrence of the
Change in Control) by which the Issuer shall purchase Debt Securities to be
purchased pursuant to the selling holder's exercise of rights on Change in
Control (the "Change in Control Purchase Date"), (d) the price specified in such
Debt Securities for their purchase by the Issuer (the "Change in Control
Purchase Price"), (e) the name and address of the Trustee, (f) the procedure for
surrendering Debt Securities to the Trustee or other designated office or agent
for payment, (g) a statement of the Issuer's obligation to make prompt payment
on proper surrender of such Debt Securities, (h) the procedure for
 
                                       17
<PAGE>   19
 
holders' exercise of rights of sale of such Debt Securities by delivery of a
"Change in Control Purchase Notice," and (i) the procedures for withdrawing a
Change in Control Purchase Notice. No purchase of any Debt Securities shall be
made if there has occurred and is continuing an Event of Default under the
Indenture (other than default in payment of the Change in Control Purchase
Price). In connection with any purchase of Debt Securities under this paragraph,
the Issuer will comply with all Federal and state securities laws, including,
specifically, Rule 13E-4, if applicable, of the Exchange Act, and any related
Schedule 13E-4 required to be submitted under such Rule. (Section 1501)
 
  Discharge, Defeasance and Covenant Defeasance
 
     The Issuer or the Company may discharge certain obligations to holders of
any series of Debt Securities that have not already been delivered to the
Trustee for cancellation and that either have become due and payable or will
become due and payable within one year (or scheduled for redemption within one
year) by depositing with the Trustee, in trust, funds in U.S. dollars or in the
Foreign Currency in which such Debt Securities are payable in an amount
sufficient to pay the entire indebtedness on such Debt Securities with respect
to principal (and premium, if any) and interest to the date of such deposit (if
such Debt Securities have become due and payable) or to the Maturity thereof, as
the case may be. (Section 401)
 
     The Indenture provides that, unless the provisions of Section 402 thereof
are made inapplicable to the Debt Securities of or within any series pursuant to
Section 301 thereof, the Issuer or the Company may elect either (a) to defease
and be discharged from any and all obligations with respect to such Debt
Securities (except for, among other things, the obligation to pay Additional
Amounts, if any upon the occurrence of certain events of taxation, assessment or
governmental charge with respect to payments on such Debt Securities and other
obligations to register the transfer or exchange of such Debt Securities, to
replace temporary or mutilated, destroyed, lost or stolen Debt Securities, to
maintain an office or agency with respect to such Debt Securities and to hold
moneys for payment in trust) ("defeasance") (Section 402(2)) or (b) to be
released from its obligations with respect to such Debt Securities under the
covenants described in "Limitation on Liens" and "Limitation on Sale/Leaseback
Transactions" above or, if provided pursuant to Section 301 of the Indenture,
its obligations with respect to any other covenant, and any omission to comply
with such obligations shall not constitute a default or an Event of Default with
respect to such Debt Securities ("covenant defeasance"). (Section 402(3))
Defeasance or covenant defeasance, as the case may be, shall be conditioned upon
the irrevocable deposit by the Issuer or the Company with the Trustee, as trust
funds in trust of an amount, in U.S. dollars or in the Foreign Currency in which
such Debt Securities are payable at Stated Maturity, or Government Obligations
(as defined below), or both, applicable to such Debt Securities which through
the scheduled payment of principal and interest in accordance with their terms
will provide money in an amount sufficient to pay the principal of (and premium,
if any) and interest on such Debt Securities on the scheduled due dates
therefor. (Section 402(4))
 
     Such a trust may only be established if, among other things, (i) the
applicable defeasance or covenant defeasance does not result in a breach or
violation of, or constitute a default under, the Indenture or any other material
agreement or instrument to which the Issuer or the Company is a party or by
which any of them is bound, (ii) no default or Event of Default with respect to
the Debt Securities to be defeased shall have occurred and be continuing on the
date of the establishment of such a trust and (iii) the Issuer or the Company
has delivered to the Trustee an Opinion of Counsel (as specified in the
Indenture) to the effect that the holders of such Debt Securities will not
recognize income, gain or loss for U.S. federal income tax purposes as a result
of such defeasance or covenant defeasance and will be subject to U.S. federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such defeasance or covenant defeasance had not
occurred, and such Opinion of Counsel, in the case of defeasance, must refer to
and be based upon a letter ruling of the Internal Revenue Service received by
the Company, a Revenue Ruling published by the Internal Revenue Service or a
change in applicable U.S. federal income tax law occurring after the date of the
Indenture. (Section 402(4)(b) and (c))

     "Foreign Currency" means any currency, currency unit or composite currency,
including, without limitation, the ECU, issued by the government of one or more
countries other than the United States of America or by any recognized
confederation or association of such governments. (Section 101)
 
     "Government Obligations" means securities which are (i) direct obligations
of the United States of America or the government or the governments in the
confederation which issued the Foreign Currency in which the Debt Securities of
a particular series are payable, for the payment of which its full faith and
credit is pledged or (ii) obligations of a Person controlled or supervised by
and acting as an agency or instrumentality of the United States of America or
such government or governments which issued the Foreign Currency in which the
Debt Securities of such series are payable, the timely payment of which is
unconditionally guaranteed as a full faith and credit obligation by the United
States of America or such other government or governments, which, in the case of
clauses (i) and (ii), are not callable or redeemable at the option of the issuer
or issuers thereof, and shall also include a depository receipt issued by a bank
or trust company as custodian with respect to any such Government Obligation or
a specific payment of interest on or principal of or any other amount with
respect to any such Government Obligation held by such custodian for the account
of the holder of such depository receipt, provided that (except as required by
law) such custodian is not authorized to make any deduction from the amount
payable to the holder of such depository receipt from any amount received by the
custodian with respect to the Government Obligation or the specific payment of
interest on or principal of or any other amount with respect to the Government
Obligation evidenced by such depository receipt. (Section 101)
 
     Unless otherwise provided in the applicable Prospectus Supplement, if after
the Issuer or the Company has deposited funds and/or Government Obligations to
effect defeasance or covenant defeasance with respect to Debt Securities of any
series, (a) the holder of a Debt Security of such series is entitled to, and
does, elect pursuant to Section 301 of the Indenture or the terms of such Debt
Security to receive payment in a currency other than that in which such deposit
has been made in respect of such Debt Security, or (b) a Conversion Event (as
defined below) occurs in respect of the Foreign Currency in which such deposit
has been made, the indebtedness represented by such Debt Security shall be
deemed to have been, and will be, fully discharged and satisfied through the
payment of the principal of (and premium, if any) and interest, if any, on such
Debt Security as such Debt Security becomes due out of the proceeds yielded by
converting the amount or other properties so deposited in respect of such Debt
Security into the currency in which such Debt Security becomes payable as a
result of such election or such Conversion Event based on (x) in the case of
payments made pursuant to clause (a) above, the applicable market exchange rate
for such currency in effect on the second business day prior to such payment
date, or (y) with respect to a Conversion Event, the applicable market exchange
rate for such Foreign Currency in effect (as nearly as feasible) at the time of
the Conversion Event. (Section 402(5))
 
     "Conversion Event" means the cessation of use of (i) a Foreign Currency
other than the ECU both by the government of the country or the confederation
which issued such Foreign Currency and for the settlement of transactions by a
central bank or other public institutions of or within the international banking
community, (ii) the ECU both within the European Monetary System and for the
settlement of transactions by public institutions of or within the European
community or (iii) any currency unit or composite currency other than the ECU
for the purposes for which it was established. Unless otherwise provided in the
applicable Prospectus Supplement, all payments of principal of (and premium, if
any) and interest on any Debt Security that are payable in a Foreign Currency
that ceases to be used by the government or confederation of issuance shall be
made in U.S. dollars. (Section 101)
 
     In the event the Issuer or the Company effects covenant defeasance with
respect to any Debt Securities and such Debt Securities are declared due and
payable because of the occurrence of any Event of Default other than an Event of
Default with respect to Sections 1005 and 1006 of the Indenture (which Sections
would no longer be applicable to such Debt Securities after such covenant
defeasance) or with respect to any other covenant as to which there has been
covenant defeasance, the amount in such Foreign Currency in which such Debt
Securities are payable, and Government Obligations on deposit with the Trustee,
will be sufficient to pay amounts due on such Debt Securities at the time of the
Stated Maturity but may not be sufficient to pay amounts due on such Debt
Securities at the time of the
 
                                       19
<PAGE>   21
 
acceleration resulting from such Event of Default. However, the Issuer or the
Company would remain liable to make payment of such amounts due at the time of
acceleration.
 
     The applicable Prospectus Supplement may further describe the provisions,
if any, permitting defeasance or covenant defeasance, including any
modifications to the provisions described above, with respect to the Debt
Securities of or within a particular series.
 
     Under the Indenture, the Issuer and the Company are required to furnish to
the Trustee annually a statement as to performance by the Issuer and the Company
of certain of their respective obligations under the Indenture and as to any
default in such performance. The Issuer and the Company are also required to
deliver to the Trustee, within five days after occurrence thereof, written
notice of any event which after notice or lapse of time or both would constitute
an Event of Default. (Section 1009)
 
  Modification and Waiver
 
     Modifications and amendments of the Indenture may be made by the Issuer,
the Company and the Trustee with the consent of the holders of not less than
66 2/3 percent of the aggregate principal amount of the Debt Securities of each
series affected thereby; provided, however, that no such modification or
amendment may, without the consent of the holder of each Debt Security affected
thereby, (a) change the Stated Maturity of the principal of, or premium, if any,
on, or any installment of principal, if any, of or interest on, or any
Additional Amounts with respect to, any Debt Security, (b) reduce the principal
amount of, or premium or interest on, or any Additional Amounts with respect to
any Debt Security, (c) change the coin or currency in which any Debt Security or
any premium or any interest thereon or any Additional Amounts with respect
thereto is payable, (d) impair the right to institute suit for the enforcement
of any payment on or after the Stated Maturity of any Debt Securities (or, in
the case of redemption, on or after the Redemption Date or, in the case of
repayment at the option of any holder, on or after the date for repayment or in
the case of a change in control, after the change in control purchase date), (e)
reduce the percentage and principal amount of the outstanding Debt Securities,
the consent of whose holders is required in order to take certain actions, (f)
change any obligation of the Issuer or the Company to maintain an office or
agency in the places and for the purposes required by the Indenture, (g) modify
or affect in any manner adverse to the holders of the Debt Securities the terms
and conditions of the obligations of the Issuer, and the Company under the
Guarantees in respect, of the due and punctual payment of principal of, any
premium on or all interest on the Debt Securities, or (h) modify any of the
above provisions. (Section 902)
 
     The holders of at least a majority in aggregate principal amount of Debt
Securities of any series may, on behalf of the holders of all Debt Securities of
such series, waive compliance by the Issuer or the Company with certain
restrictive provisions of the Indenture. (Section 1008) The holders of not less
than a majority in aggregate principal amount of Debt Securities of any series
may, on behalf of all holders of Debt Securities of such series, waive any past
default and its consequences under the Indenture with respect to the Debt
Securities of such series, except a default (a) in the payment of principal of
(or premium, if any) or any interest on or any Additional Amounts with respect
to Debt Securities of such series or (b) in respect of a covenant or provision
of the Indenture that cannot be modified or amended without the consent of the
holder of each Debt Security of any series. (Section 513)
 
  Consolidation, Merger and Sale of Assets
 
     The Company may, without the consent of the holders of the Debt Securities,
consolidate or merge with or into, or convey, transfer or lease its properties
and assets as an entirety or substantially as an entirety to, any Person that is
organized and validly existing under the laws of any domestic jurisdiction, or
may permit any such Person to consolidate with or merge into the Company or
convey, transfer or lease its properties and assets as an entirety or
substantially as an entirety to the Company, provided that any successor Person
assumes the Company's obligations on the Debt Securities and under the
Indenture, that after giving effect to the transaction no Event of Default, and
no event which, after notice
 
                                       20
<PAGE>   22
 
or lapse of time or both, would become an Event of Default, shall have occurred
and be continuing, and that certain other conditions are met. (Section 801)
 
     The Issuer may, without the consent of the holders of the Debt Securities,
consolidate or merge into, or convey, transfer or lease its properties and
assets substantially as an entirety to, any Person organized and validly
existing under the laws of the jurisdiction of organization of such Person, or
may permit any such Person to consolidate with or merge into the Issuer or
convey, transfer or lease its properties and assets substantially as an entirety
to the Issuer, provided that (a) any successor Person assumes the Issuer's
obligations on the Debt Securities and under the Indenture (including any
obligation to pay any Additional Amounts), (b) immediately after giving effect
to such transaction, no Event of Default, and no event which, after notice or
lapse of time or both, would become an Event of Default, shall have occurred and
be continuing, and (c) any such successor Person shall expressly agree by a
supplemental indenture (i) to immediately indemnify (pursuant to the procedure
described above under "-- Indemnification Procedure") the holder of each Debt
Security against (A) any tax, assessment or governmental charge imposed on such
holder or required to be withheld or deducted from any payment to such holder as
a consequence of such consolidation, merger, conveyance, transfer or lease, and
(B) any other tax costs or other tax expenses of the act of such consolidation,
merger, conveyance, transfer or lease (except that if the Company or any such
Person delivers an opinion of an independent counsel or a tax consultant of
recognized standing that the holder will not recognize income, gain or loss for
U.S. federal income tax purposes as a result of such transaction, a holder will
have such right to indemnification only if and when gain for U.S. federal income
tax purposes is actually imposed on such holder), and (ii) that all payments
pursuant to the Debt Securities in respect of the principal of and any premium
and interest on the Debt Securities, as the case may be, shall be made without
withholding or deduction for, or on account of, any present or future taxes,
duties, assessments or governmental charges of whatever nature imposed or levied
by or on behalf of the jurisdiction of organization of such successor Person or
any political subdivision or taxing authority thereof or therein, unless such
taxes, duties, assessments or governmental charges are required by such
jurisdiction or any such subdivision or authority to be withheld or deducted, in
which case such successor Person will pay such additional amounts of, or in
respect of, principal and any premium and interest ("Successor Additional
Amounts") as will result (after deduction of such taxes, duties, assessments or
governmental charges and any additional taxes, duties, assessments or
governmental charges payable in respect of such) in the payment to each holder
of a Debt Security of the amounts which would have been payable pursuant to the
Debt Securities had to such withholding or deduction been required, subject to
the same exceptions as would apply with respect to the payment by the Issuer of
Additional Amounts in respect of the Debt Securities (see "--Payment of
Additional Amounts"). (Section 802)
 
  Payment of Additional Amounts
 
     All payments of, or in respect of, principal of and any premium and
interest on any Debt Securities issued by the Issuer shall be made without
withholding or deduction for, or on account of, any present or future taxes,
duties, levies, assessments or governmental charges of whatever nature imposed
or levied by or on behalf of the jurisdiction (or any political subdivision or
taxing authority thereof or therein) in which the Issuer is incorporated or
resident (or deemed for tax purposes to be resident) (the "applicable taxing
jurisdiction"), unless such taxes, duties, levies, assessments or governmental
charges are required by the applicable taxing jurisdiction or any such
subdivision or authority to be withheld or deducted. In that event, the Issuer
will pay by way of additional interest such additional amounts of, or in respect
of, principal of and any premium and interest ("Additional Amounts") as will
result (after deduction of such taxes, duties, levies, assessments or
governmental charges and any additional taxes, duties, levies, assessments or
governmental charges payable in respect of such Additional Amounts) in the
payment to each holder of such Debt Securities of the amounts which would have
been payable in
 
                                       21
<PAGE>   23
 
respect of such Debt Securities had no such withholding or deduction been
required (Section 1004), except that no Additional Amounts shall be so payable
for or on account of:
 
          (a) any tax, duty, levy, assessment or other governmental charge which
     would not have been imposed but for the fact that such holder:
 
             (i) was a resident, domiciliary or national of, or engaged in
        business or maintained a permanent establishment or was physically
        present in, the applicable taxing jurisdiction or otherwise had some
        connection with the applicable taxing jurisdiction other than the mere
        ownership of such Debt Security;
 
             (ii) presented (if presentation is required) such Debt Security for
        payment in the applicable taxing jurisdiction, unless such Debt Security
        could not have been presented for payment elsewhere;
 
             (iii) presented (if presentation is required) such Debt Security as
        the case may be, more than 30 days after the date on which the payment
        in respect of such Debt Security first became due and payable or
        provided for, whichever is later, except to the extent that the holder
        would have been entitled to such Additional Amounts if it had presented
        such debt Security for payment on any days within such period of 30
        days;
 
             (iv) is, directly or indirectly, taken to be an Associate of the
        Issuer; or
 
             (v) entered into or participated in a scheme to avoid Australian
        interest withholding tax, being a scheme which the Issuer was neither a
        party to nor participated in, in respect of which the Australian
        Commissioner of Taxation has made a determination that Australian
        interest withholding tax is payable in respect of the amount.
 
          (b) any estate, inheritance, gift, sale, transfer, personal property
     or similar tax, assessment or other governmental charge;
 
          (c) any tax, assessment or other governmental charge which is payable
     otherwise than by withholding or deduction from payments of, or in respect
     of, principal of or any premium or interest on the Debt Securities;
 
          (d) any tax, assessment or other governmental charge that is imposed
     or withheld by reason of the failure to comply by the holder or the
     beneficial owner of a Debt Security with a request of the Issuer addressed
     to the holder (i) to provide information concerning the nationality,
     residence or identity of the holder or such beneficial owner or (ii) to
     make any declaration or other similar claim or satisfy any information or
     reporting requirement, which, in the case of (i) or (ii), is required or
     imposed by a statute, treaty, regulation or administrative practice of the
     applicable taxing jurisdiction as a precondition to exemption from all or
     part of such tax, assessment or other governmental charge; or
 
          (e) any combination of items (a), (b), (c) and (d);
 
nor shall Additional Amounts be paid with respect to any payment of the
principal of or any premium or interest on any such Debt Security to any holder
who is a fiduciary or partnership or other than the sole beneficial owner of
such payment to the extent such payment would be required by the laws of the
applicable taxing jurisdiction to be included in the income for tax purposes of
a beneficiary or settlor with respect to such fiduciary or a member of such
partnership or a beneficial owner who would not have been entitled to such
Additional Amounts had it been the holder of the Debt Security.
 
     Whenever there is mentioned, in any context, the payment of principal of,
or any premium or interest on, or in respect of, any Debt Securities of any
series issued by the Issuer or the net proceeds received on the sale or exchange
of any Debt Security of any series issued by the Issuer, such mention shall be
deemed to include mention of the payment of Additional Amounts provided for in
the Indenture to the
 
                                       22
<PAGE>   24
 
extent that, in such context, Additional Amounts are, were or would be payable
in respect thereof pursuant to the Indenture.
 
  Redemption for Taxation Reasons
 
     If as the result of any change in or any amendment to the laws, regulations
or published tax rulings of the applicable taxing jurisdiction affecting
taxation, or any change in the official administration, application or
interpretation of such laws, regulations or published tax rulings either
generally or in relation to any Debt Securities issued by the Issuer, which
change or amendment becomes effective on or after the original issue date of
such Debt Securities or which change in official issue date of such Debt
Securities or which change in official administration, application or
interpretation shall not have been available to the public prior to such issue
date, it is determined by the Company that the Issuer (a) would be required to
pay any Additional Amounts pursuant to the Indenture or the terms of any Debt
Security (i) in respect of interest on the next succeeding interest Payment Date
or (ii) in respect of the principal of any Discounted Securities on the date of
such determination, assuming that a payment in respect of such principal were
required to be made on such date under the terms of the Debt Securities, and (b)
such obligation cannot be avoided by the Company or the Issuer taking reasonable
measures available to it, in either case (i) or (ii) above the Issuer may, at
its option, redeem all (but not less than all) the Debt Securities of any series
in respect of which such Additional Amounts would be so payable at any time,
upon not less than 30 nor more than 60 days' written notice as provided in the
Indenture, at a Redemption Price equal to 100 percent of the principal amount
thereof plus accrued interest to the date fixed for redemption (except that any
such Debt Securities that are Outstanding Discounted Securities may be redeemed
at the Redemption Price specified in the terms thereof); provided, however, that
(a) no such notice of redemption may be given earlier than 60 days prior to the
earliest date on which the Issuer would be obligated to pay such Additional
Amounts were a payment then due in respect of the Debt Securities, and (b) at
the time any such redemption notice is given, such obligation to pay such
Additional Amounts must remain in effect. If (a) the Issuer shall have on any
date (the "Succession Date") consolidated with or merged into, or conveyed or
transferred or leased its properties and assets substantially as an entirety to,
any Successor referred to under "--Consolidation, Merger and Sale of Assets"
above which is organized under the laws of any jurisdiction other than the
United States of America, any State thereof or the District of Columbia or the
jurisdiction in which the Issuer is organized, (b) as the result of any change
in or any amendment to the laws, regulations or published tax rulings of such
jurisdiction or organization, or of any political subdivision or taxing
authority thereof or therein, affecting taxation, or any change in the official
administration, application or interpretation of such laws, regulations or
published tax rulings either generally or in relation to any particular Debt
Securities, which change or amendment becomes effective on or after the
Succession Date or which change in official administration, application or
interpretation shall not have been available to the public prior to such
Succession Date and is notified to the Issuer, such Successor would be required
to pay any Successor Additional Amounts (as defined under "-- Consolidation,
Merger and Sale of Assets" above) pursuant to the Indenture or the terms of any
Debt Securities (i) in respect of interest on any Debt Securities on the next
succeeding Interest Payment Date, or (ii) in respect of the principal of any
Discounted Securities on the date of such determination (assuming such principal
were required to be paid on such date under the terms of the Debt Securities)
and (c) such obligation cannot be avoided by the Company or such Successor
taking reasonable measures available to it, such Issuer or Successor may at its
option, redeem all (but not less than all) of the Debt Securities of any series
in respect of which such Successor Additional Amounts would be so payable at any
time, upon not less than 30 nor more than 60 days' written notice as provided in
the Indenture, at a Redemption Price equal to 100 percent of the principal
amount thereof plus accrued interest to the date fixed for redemption (except
that any such Debt Securities that are Outstanding Discounted Securities may be
redeemed at the Redemption Price specified in the terms thereof); provided,
however, that (a) no such notice of redemption may give earlier than 60 days
prior to the earliest date on which a Successor would be obligated to pay such
Successor Additional Amounts were a payment then due in respect of the Debt
Securities, and (b) at the time any such redemption notice is given, such
obligation to pay such Successor Additional Amounts must remain in effect.

  Concerning the Trustee
 
     Unless otherwise specified in the applicable Prospectus Supplement, The
Chase Manhattan Bank, New York, New York will be the Trustee under the
Indenture.
 
  Service of Process
 
     The Indenture provides that the Company and the Issuer will irrevocably
appoint CT Corporation System, 1633 Broadway, New York, New York 10019, as its
agent for service of process in any suit, action or proceeding with respect to
such Indenture or the Debt Securities issued thereunder and for actions brought
under the federal or state securities laws brought in any federal or state court
located in New York City, and submit to such jurisdiction.
 
  Governing Law
 
     The Indenture, the Debt Securities and the Guarantees will be governed by
and construed in accordance with the laws of the State of New York, but without
regard to the principles of conflicts of laws thereof, except as may otherwise
be required by mandatory provisions of law and except that all matters governing
the authorization and execution of the Indenture and the Debt Securities by the
Issuer will be governed by and construed in accordance with the laws of the
jurisdiction of incorporation of the Issuer.
 
                           DTC BOOK-ENTRY-ONLY SYSTEM
 
     Unless otherwise indicated in the applicable Prospectus Supplement, the
Debt Securities will be registered under a book-entry-only system maintained by
DTC. The book-entry-only system will evidence ownership interests in the Debt
Securities in book-entry-only form. Purchasers of ownership interests in the
Debt Securities will not receive certificates representing their interests in
the Debt Securities purchased. Transfers of ownership interests will be effected
on the records of DTC and its participating organizations (the "DTC
Participants") pursuant to rules and procedures established by DTC.
 
     Certain of the following information concerning the procedures and record
keeping with respect to ownership interests in the Debt Securities, payment of
interest and other payments on the Debt Securities to DTC Participants or
Beneficial Owners (as hereafter defined), confirmation and transfer of ownership
interests in the Debt Securities and other related transactions by and between
DTC, the DTC Participants and Beneficial Owners is based solely on information
contained in a published report of DTC.
 
     DTC, an automated clearinghouse for securities transactions, will act as
securities depository for the Debt Securities. DTC is a limited-purpose trust
company organized under the laws of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code, and a "clearing agency" registered pursuant to the
provisions of Section 17A of the 1934 Act. DTC was created to hold securities of
the DTC Participants and to facilitate the clearance and settlement of
securities transactions among DTC Participants in such securities through
electronic book-entry changes in accounts of the DTC Participants, thereby
eliminating the need for physical movement of security certificates. DTC
Participants include securities brokers and dealers, banks, trust companies,
clearing corporations and certain other organizations, some of which (and/or
their representatives) own DTC. Access to the DTC system is also available to
others such as banks, brokers, dealers and trust companies that clear through or
maintain a custodial relationship with a DTC Participant, either directly or
indirectly (the "Indirect Participants").
 
     The ownership of the fully-registered Debt Securities will be registered in
the name of Cede & Co., as nominee for DTC. Ownership interests in the Debt
Securities may be purchased by or through DTC Participants and will be recorded
on the records of the DTC Participants, whose interests in turn will be recorded
on a computerized book-entry-only system operated by DTC. Such DTC Participants
and the person for whom they acquire interests in the Debt Securities as
nominees ("Beneficial Owner") will not receive Debt Security certificates, but
each such DTC Participant will receive a credit balance in the
 
                                       24
<PAGE>   26
 
records of DTC in the amount of such DTC Participant's interest in the Debt
Securities, which will be confirmed in accordance with DTC's standard
procedures. Each such Beneficial Owner for whom a DTC Participant acquires an
interest in the Debt Securities, as nominee, may desire to make arrangements
with such DTC Participant to have all communications of the Company and the
Trustee to DTC which may affect such Beneficial Owner forwarded in writing by
such DTC Participant and to have notifications made of all payments of principal
and interest with respect to his beneficial interest. The Issuer, the Company
and the Trustee will treat DTC (or its nominee) as the sole and exclusive owner
of the Debt Securities registered in its name for the purposes of payment of the
principal and interest on the Debt Securities, giving any notice permitted or
required to be given to holders under the Indenture, registering the transfer of
Debt Securities, and for all other purposes whatsoever, and shall not be
affected by any notice to the contrary. Neither the Issuer, the Company nor the
Trustee shall have any responsibility or obligation to any DTC Participant, any
person claiming a beneficial ownership interest in the Debt Securities under or
through DTC or any DTC Participant, or any other person which is not shown on
the registration books of the Trustee as being a holder, with respect to: (i)
the accuracy of any records maintained by DTC or any DTC Participant; (ii) the
payment by DTC or any DTC Participant of any amount in respect of the principal
or interest on the Debt Securities; (iii) any notice which is permitted or
required to be given to holders thereunder or under the conditions to transfers
or exchanges adopted by the Issuer or Company; or (iv) any other action taken by
DTC as a holder. Principal and interest on the Debt Securities will be paid by
the Trustee. Disbursement of such payments to the DTC Participants is the
responsibility of DTC and disbursement of such payments to the Beneficial Owners
is the responsibility of the DTC Participants or the Indirect Participants.
NEITHER THE ISSUER, THE COMPANY NOR THE TRUSTEE WILL HAVE ANY RESPONSIBILITY OR
OBLIGATIONS TO SUCH DTC PARTICIPANTS OR THE PERSONS FOR WHOM THEY ACT AS
NOMINEES WITH RESPECT TO THE PAYMENTS TO OR THE PROVIDING OF NOTICE FOR THE DTC
PARTICIPANTS, OR THE INDIRECT PARTICIPANTS, OR THE BENEFICIAL OWNERS SO LONG AS
CEDE & CO., AS NOMINEE OF DTC, IS THE REGISTERED OWNER OF THE DEBT SECURITIES,
REFERENCES HEREIN TO THE SECURITY HOLDERS OR REGISTERED OWNERS OF THE DEBT
SECURITIES SHALL MEAN CEDE & CO., AND SHALL NOT MEAN THE BENEFICIAL OWNERS.
 
     For every transfer and exchange of beneficial ownership of Debt Securities,
a Beneficial Owner may be charged a sum sufficient to cover any tax, fee or
other governmental charge that may be imposed in relation thereto.
 
     When reference is made to any action which is required or permitted to be
taken by the Beneficial Owners, such reference shall only relate to action by
such Beneficial Owner, or others permitted to act (by statute, regulation or
otherwise) on behalf of such Beneficial Owners for such purposes. When notices
are given, they shall be sent by the Trustee to DTC only. Conveyance of notices
and other communications by DTC to DTC Participants and Indirect Participants
and in turn by DTC Participants and Indirect Participants to Beneficial Owners
will be governed by arrangements among them, subject to any statutory and
regulatory requirements then in effect.
 
     Principal and interest payments on the Debt Securities will be made to DTC
or its nominee, Cede & Co., as registered owner of the Debt Securities. Upon
receipt of any such payments, DTC's current practice is to immediately credit
the accounts of the DTC Participants in accordance with their respective
holdings shown on the records of DTC. Payments by DTC Participants and Indirect
Participants to Beneficial Owners will be governed by standing instructions and
customary practices, as is now the case with securities held for the accounts of
customers in bearer form or registered in "street name," and will be the
responsibility of such DTC Participant or Indirect Participant.
 
     DTC may determine to discontinue providing its services with respect to the
Debt Securities at any time by giving notice to the Issuer or the Company and
discharging its responsibilities with respect thereto under applicable law. In
addition, the Issuer or the Company may determine that continuation of the
system of book-entry-only transfers through DTC (or a successor securities
depository) is not in the best interests of the Beneficial Owners or is
burdensome to the Issuer or the Company. If for either reason the
book-entry-only system is discontinued, certificates for the Debt Securities
will be delivered to the Beneficial Owners thereof.
 
                                       25
<PAGE>   27
 
     Certain of the information contained in this sub-section has been extracted
from a report from DTC. No representation is made by the Issuer or the Company
as to the completeness or the accuracy of such information or as to the absence
of material adverse changes in such information subsequent to the date hereof.
 
  Same-Day Settlement and Payment
 
     Unless otherwise indicated in the applicable Prospectus Supplement,
settlement for the Debt Securities will be made by a purchaser in immediately
available funds. While the Debt Securities are in the book-entry-only system
described above, all payments of principal and interest will be made by the
Trustee on behalf of the Issuer or the Company to DTC in immediately available
funds.
 
     Secondary trading in long-term debt securities is generally settled in
clearing-house or next-day funds. Unless otherwise set forth in the applicable
Prospectus Supplement, while the Debt Securities are in the book-entry-only
system described above, they will trade in DTC's Same-Day Fund Settlement System
until maturity. During such period, secondary market trading activity in the
Debt Securities will settle in immediately available funds. No assurance can be
given as to the effect, if any, of settlement in immediately available funds on
the trading activity in the Debt Securities.
 
                           CERTAIN TAX CONSIDERATIONS
 
     The following summary of certain United States federal income and
Australian tax consequences of the purchase, ownership and disposition of the
Debt Securities is based upon laws, regulations, rulings and decisions now in
effect, all of which are subject to change or possible differing
interpretations. It deals only with Debt Securities held as capital assets and
does not purport to address all aspects of United States federal income or
Australian taxes that may be relevant to an investment in the Debt Securities,
nor does it address the United States or Australian tax treatment applicable to
persons in special tax situations, such as financial institutions, insurance
companies, regulated investment companies, dealers in securities or currencies,
persons holding Debt Securities as a hedge against currency risks or as a
position in a "straddle" for tax purposes, or persons whose functional currency
is not the United States dollar. It also does not deal with holders other than
original purchasers (except where otherwise specifically noted). Persons
considering the purchase of the Debt Securities should consult their own tax
advisors concerning the application of United States federal income and
Australian tax laws to their particular situations as well as any consequences
of the purchase, ownership and disposition of the Debt Securities arising under
the laws of any other taxing jurisdiction.
 
     The statements below regarding United States federal tax consequences are
based upon the provisions of the United States Internal Revenue Code of 1986, as
amended (the "Code") and regulations, rulings and judicial decisions thereunder
as of the date of this Prospectus. Such authorities may be repealed, revoked or
modified, in which case tax consequences different from those discussed below
could result.
 
     As used herein, the term "U.S. holder" means a beneficial owner of a Debt
Security that is for United States federal income tax purposes (i) a citizen or
resident of the United States, (ii) a corporation, partnership or other entity
created or organized in or under the laws of the United States or of any
political subdivision thereof (other than a partnership that is not treated as a
United States person under any applicable Treasury regulations), (iii) an estate
the income of which is subject to United States federal income taxation
regardless of its source, (iv) a trust if a court within the United States is
able to exercise primary supervision of the administration of the trust and one
or more United States persons have the authority to control all substantial
decisions of the trust, or (v) any other person whose income or gain in respect
of a Debt Security is effectively connected with the conduct of a United States
trade or business. Notwithstanding the preceding clause (iv), to the extent
provided in regulations, certain trusts in existence on August 20, 1996 and
treated as United States persons prior to such date that elect to continue to be
so treated also shall be considered U.S. holders. As used herein, the term
"non-U.S. holder" means a holder of a Debt Security that is not a U.S. holder.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
 
     The following summary of United States federal income tax considerations is
based on the advice of Woodard, Hall & Primm, P.C., Houston, Texas, special tax
counsel to the Company, whose opinion is set forth herein.
 
     Taxation of Interest. The gross amount of interest (including Additional
Amounts, if any, accrued or received in respect of the Debt Securities)
generally will be includible in the gross income of a U.S. holder and such
income generally will be treated as foreign source passive income for United
States federal income tax purposes. If any foreign source taxes were to be paid
or withheld in respect of payments on the debt securities, a U.S. holder may be
eligible, subject to a number of complex limitations, for a foreign tax credit.
 
     Taxation of Dispositions. A U.S. holder that owns the Debt Securities as
capital assets will recognize gain or loss for United States federal income tax
purposes upon the sale or other disposition of the Debt Securities in an amount
equal to the difference between the amount realized and the U.S. holder's tax
basis in the Debt Securities. Gain or loss recognized by a U.S. holder on a sale
or other disposition of the Debt Securities will be (i) mid-term if the Debt
Securities have been held for 18 months or less, but more than one year, or (ii)
long-term if the Debt Securities have been held for more than 18 months.
 
     A U.S. holder of a Debt Security may recognize gain or loss for United
States federal income tax purposes equal to the difference between the fair
market value of the Debt Security and such U.S. holder's adjusted tax basis in
such Debt Security in the event that (a) the Company consolidates with or merges
into any other Person or conveys, transfers or leases its properties and assets
substantially as an entirety to any other Person, (b) the Company assumes the
obligations of the Issuer under any series of Debt Securities, (c) the Issuer
consolidates or merges into any other Person, (d) the Issuer exercises its
option to redeem the Debt Securities or (e) the Issuer assigns its obligations
under any series of Debt Securities to any other Person. Additionally, a U.S.
holder will recognize on disposition of a Debt Security the amount of any
accrued but unpaid interest and the amount of any market discount associated
with such Debt Security. The Indenture provides that, where a U.S. holder (other
than entities then exempt from taxation under Section 501 of the Code)
recognizes gain for United States federal income tax purposes as a result of
such a merger or assumption, any such Person (in the case of (b) or (c)) or the
Company (in the case of (b)) shall indemnify such U.S. holder of a Debt Security
in an amount equal to the sum of (i) the Indemnification Amount and (ii) the
product of the Indemnification Amount and the highest marginal tax rate in
effect at the time of such above-described transaction. For a description of the
procedures by which a U.S. holder may exercise its indemnification rights, see
"Description of Debt Securities and Guarantees -- Indemnification Procedure"
above.
 
     Original Issue Discount. The Debt Securities may be issued with original
issue discount for United States federal income tax purposes. U.S. holders of
the Debt Securities will be required to include original issue discount in gross
income as it accrues, on a constant-yield basis, regardless of their method of
accounting.
 
     The amount of the original issue discount in the Debt Securities will be
the difference between the stated redemption price at maturity and the issue
price of the Debt Securities. The "issue price" of the Debt Securities will be
the price at which a substantial amount of the Debt Securities are sold to the
public for cash (excluding sales to bond houses, brokers or similar persons or
organizations acting in the capacity as underwriters, placement agents or
wholesalers).
 
     The "stated redemption price" at maturity of a debt instrument is the total
of all payments to be made on the instrument other than payments of qualified
stated interest. "Qualified stated interest" includes only interest that is
unconditionally payable in cash or property (other than debt instruments of the
Issuer) at least annually at a single fixed rate that appropriately takes into
account the length of the interval between payments.
 
     Holders of the Debt Securities must include in gross income, as interest,
the daily portions of original issue discount for each day during the taxable
year on which the Debt Securities were held. The daily
 
                                       27
<PAGE>   29
 
portions of the original issue discount will be determined by allocating to each
day in each accrual period the ratable portion of the original issue discount
allocable to that period. (The accrual periods may be of any length and may vary
in length over the term of a debt instrument, provided that each accrual period
is no longer than one year, and each scheduled payment of interest or principal
occurs on either the final day or the first day of an accrual period.) The
original issue discount allocable to an accrual period will equal the product of
the adjusted issue price of the Debt Securities at the beginning of the accrual
period and the Debt Securities' yield to maturity. The adjusted issue price of
the Debt Securities at the start of any accrual period will be the issue price
of the Debt Securities increased by the amount of the original issue discount
that has accrued in all previous accrual periods and decreased by the amount of
any payments previously made on the first day of the current accrual period.
Because the U.S. holders of the Debt Securities will include original issue
discount in income as it accrues, actual payments of cash interest (other than
qualified stated interest) on the Debt Securities will not trigger any
additional interest income to the holders.
 
     Information Reporting and Backup Withholding. The Company, on behalf of the
Issuer, will provide annual information statements to U.S. holders of the Debt
Securities and information returns to the United States Internal Revenue Service
(the "IRS") regarding the amount of original issue discount, if any, that
accrued on the Debt Securities during the year.
 
     The Company, on behalf of the Issuer, its paying agent, or other
withholding agent may be required to withhold and remit to the IRS 31 percent of
the interest payments on the Debt Securities if the IRS notifies the Company, on
behalf of the Issuer, its paying agent, or other withholding agent that the U.S.
holder thereof is subject to backup withholding, or if such U.S. holder fails to
provide a taxpayer identification number, provides an obviously incorrect
taxpayer identification number, fails to certify that such holder is not subject
to back withholding, or otherwise fails to comply with applicable requirements
of the backup withholding rules. Certain holders (including, among others,
corporations) are not subject to these backup withholding rules. Any amount paid
as backup withholding would be creditable against the U.S. holder's United
States federal income tax liability.
 
AUSTRALIAN TAX CONSIDERATIONS
 
     The following is a general summary of the Australian tax position of
holders of Debt Securities, where such Debt Securities are held as investments.
The statements below are based on the provisions of the Income Tax Assessment
Act 1936 (the "Tax Act"), regulations, published rulings and court decisions now
in effect, all of which are subject to change (including changes in
interpretation) possibly with retroactive effect. The comments below do not
constitute tax advice. Prospective investors should consult their professional
tax advisers.
 
     The following summary is based on the assumption that no holder of Debt
Securities will be either a:
 
          (i) resident of Australia for the purposes of the Tax Act; or
 
          (ii) non-resident of Australia with a permanent establishment or fixed
     base in Australia.
 
     Special considerations apply to holders in these circumstances which are
not addressed in the following summary.
 
DEBT SECURITIES NOT ISSUED AT A DISCOUNT
 
  Payments of Principal, Premium and Interest
 
     Non-resident holders of Debt Securities not issued at a discount will not
be subject to Australian income tax on payments of principal, premium (to the
extent that the premium is not regarded as interest) and interest, other than
interest withholding tax (currently levied at a flat rate of 10%).
 
                                       28
<PAGE>   30
 
     Under section 128F of the Tax Act, interest on debentures (the definition
of which would include the Debt Securities) issued outside Australia by
companies resident in Australia is exempt from Australian interest withholding
tax if:
 
          (i) the interest is paid outside Australia; and
 
          (ii) the Issuer or at least one of the underwriters of the Debt
     Securities satisfies one of a number of alternative public offer tests
     specified in section 128F of the Tax Act.
 
     The Issuer and any underwriter engaged by the Issuer in connection with any
offer and sale of the Debt Securities will aim to satisfy one or more of the
public offer tests in respect of the Debt Securities. However, if the public
offer tests are not satisfied then interest withholding tax of ten percent will
be deducted from interest payments. See "Description of Debt Securities and
Guarantees-Payment of Additional Amounts."
 
  Gains on Sale or Redemption
 
     Gains made on the disposal of any Debt Security held by a non-resident of
Australia as a capital asset will not be subject to Australian income tax
provided:
 
          (i) the Debt Securities have not at any time been used by the holder
     in carrying on a trade or business wholly or partly at or through a
     permanent establishment in Australia; and
 
          (ii) the gain does not have an Australian source.
 
     The source of any gain derived on the disposal of a Debt Security will be
determined by the factual circumstances of the disposal. The profit on disposal
of the Debt Securities should not have an Australian source where the Debt
Security is acquired and disposed of pursuant to contractual arrangements
entered into and concluded outside Australia and the seller and the purchaser of
the Debt Securities are not residents of Australia and do not have permanent
establishments in Australia.
 
     Section 128F does not provide an exemption for gains made on the disposal
of Debt Securities.
 
DEBT SECURITIES ISSUED AT A DISCOUNT
 
  Tax on Discount Component
 
     If the Debt Securities are issued at a discount such that it is reasonably
likely at the time of issue that the sum of all payments (other than interest
which is expressed to be payable at intervals of not more than 1 year) will
exceed the issue price of the Debt Securities by an amount greater than 1.5
percent, they will be treated as a "qualifying security" for Australian tax
purposes. Australian interest withholding tax may be payable on the discount
component when the Debt Securities are redeemed. The current rate of withholding
tax is ten percent. However, as discussed above, an exemption from withholding
tax may be available under section 128F of the Tax Act in these circumstances
depending on whether a public offer test specified in Section 128F is satisfied.
 
  Gains on Sale
 
     Where a non-resident who does not carry on business at or through a
permanent establishment in Australia disposes of Debt Securities which were
issued at discount, section 128AA of the Tax Act may apply to deem any excess
between the sale price paid by the purchaser and the issue price of the Debt
Securities to constitute interest for Australian withholding tax purposes. Where
section 128AA of the Tax Act applies, the seller of the Debt Securities may be
subject to Australian interest withholding tax in respect of the deemed interest
received. Section 128F does not provide an exemption from interest withholding
tax in those circumstances.
 
     With the exception of the possible interest withholding tax implications
referred to immediately above, the description of the Australian taxation
consequences applicable on the sale or redemption of Debt Securities not issued
at a discount also applies to Debt Securities issued at a discount.
 
                                       29
<PAGE>   31
 
AUSTRALIAN DEATH DUTIES
 
     Under current Australian law, no Australian State or Federal estate duty or
other inheritance taxes will be payable in respect of the Debt Securities on the
death of a holder, irrespective of the holder's domicile.
 
                              PLAN OF DISTRIBUTION
 
     The Issuer or the Company may sell the Debt Securities (i) through
underwriters or dealers, (ii) directly to a limited number of institutional
purchasers or to a single purchaser, (iii) through agents, or (iv) through any
combination of the above. An accompanying Prospectus Supplement will set forth
the terms of the offering of the Debt Securities offered thereby, including the
name or names of any underwriter, the purchase price of the Debt Securities and
the net proceeds to the Issuer from such sale, any underwriting discounts and
other items constituting underwriters' compensation, any initial public offering
price and any discounts or concessions allowed or reallowed or paid to dealers.
 
     If underwriters are used in the sale of Debt Securities, such Debt
Securities will be acquired by the underwriters for their own account and may be
resold from time to time in one or more transactions, including negotiated
transactions, at a fixed public offering price or at varying prices determined
at the time of sale. Unless otherwise set forth in the Prospectus Supplement,
the several obligations of the underwriters to purchase any Debt Securities
offered thereby will be subject to certain conditions precedent and the
underwriters will be obligated to take and pay for all of such Debt Securities,
if any are taken.
 
     The Debt Securities may be sold directly by the Issuer, the Company or
through underwriters or agents designated by the Issuer or the Company from time
to time. Any agent involved in the offer or sale of the Debt Securities will be
named, and any commissions payable by the Issuer to such agents will be set
forth, in an accompanying Prospectus Supplement. Unless otherwise indicated in
such Prospectus Supplement, any such agent will be acting on a reasonable
efforts basis for the period of its appointment.
 
     If so indicated in the Prospectus Supplement, the Issuer or the Company
will authorize underwriters or other persons acting as the Issuer's or the
Company's agents to solicit offers by certain institutions to purchase Debt
Securities from the Issuer pursuant to contracts providing for payment and
delivery on a future date. Institutions with which such contracts may be made
include commercial and savings banks, insurance companies, pension funds,
investment companies, educational and charitable institutions and others, but in
all cases such institutions must be approved by the Issuer and the Company. The
obligations of any purchaser under such contract will be subject to the
condition that the purchase of the offered Debt Securities shall not at the time
of delivery be prohibited under the laws of the jurisdiction to which such
purchaser is subject. The underwriters and such other agents will not have any
responsibility in respect to the validity of performance of such contracts.
 
     Certain of the underwriters or agents and their associates may be customers
of, engage in transactions with and perform services for the Company or the
Issuer in the ordinary course of business.
 
     Agents and underwriters may be entitled under agreements entered into with
the Company and the Issuer to indemnification by the Company and the Issuer
against certain civil liabilities, including liabilities under the Securities
Act.
 
     The place and time of delivery for the Debt Securities in respect of which
this Prospectus is delivered are set forth in the accompanying Prospectus
Supplement.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
THE COMPANY
 
     The Company's Certificate of Incorporation provides that the Company shall,
to the full extent permitted under the Delaware General Corporation Law,
indemnify its officers, directors, employees and agents.
 
     Section 145 of the Delaware General Corporation Law, inter alia, authorizes
a corporation to indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit or
proceeding (other than an action by or in the right of the corporation) because
such person is or was a director, officer, employee or agent of the corporation
or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation or other enterprise, against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by him in connection with such suit or
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the corporation, and, with respect
to any criminal action or proceeding, had no reason to believe his conduct was
unlawful. Similar indemnity is authorized for such persons against expenses
(including attorneys' fees) actually and reasonably incurred in defense or
settlement of any such pending, completed or threatened action or suit by or in
the right of the corporation if such person acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
corporation, and provided further that (unless a court of competent jurisdiction
otherwise provides) such person shall not have been adjudged liable to the
corporation. Any such indemnification may be made only as authorized in each
specific case upon a determination by the stockholders or disinterested
directors that indemnification is proper because the indemnitee has met the
applicable standard of conduct.
 
     Section 145 further authorizes a corporation to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation or enterprise,
against any liability asserted against him and incurred by him in any such
capacity, or arising out of his status as such, whether or not the corporation
would otherwise have the power to indemnify him. The Company maintains policies
insuring its and its subsidiaries' officers and directors against certain
liabilities for actions taken in such capacities, including liabilities under
the Securities Act of 1933, as amended.
 
                                      II-1
<PAGE>   35
 
     Article VII of the Company's bylaws provides, in substance, that directors,
officers, employees and agents of the Company shall be indemnified to the extent
permitted by Section 145 of the Delaware General Corporation Law. Additionally,
Article Seventeen of the Company's Restated Certificate of Incorporation
eliminates in certain circumstances the monetary liability of directors of the
Company for a breach of their fiduciary duty as directors. These provisions do
not eliminate the liability of a director (i) for a breach of the director's
duty of loyalty to the corporation or its stockholders; (ii) for acts or
omissions by the director not in good faith; (iii) for acts or omissions by a
director involving intentional misconduct or a knowing violation of the law;
(iv) under Section 174 of the Delaware General Corporation Law (relating to the
declaration of dividends and purchase or redemption of shares in violation of
the Delaware General Corporation Law); and (v) for transactions from which the
director derived an improper personal benefit.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended, may be permitted to directors, officers and controlling
persons of the Company pursuant to the above provisions or otherwise, the
Company has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act of 1933 and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Company of expenses incurred or paid by a director, officer or controlling
person of the Company in the successful defense of any action, suit or
proceeding) is asserted against the Company by such director, officer or
controlling person in connection with the securities being registered, the
Company will, unless in the opinion of its counsel the matter has been settled
by controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act of 1933 and will be governed by the final
adjudication of such issue.
 
THE ISSUER
 
     Section 241 of the Corporations Law of Australia (the "Corporations Law")
prohibits a corporation (or any of its affiliates) from giving an indemnity to
any person who is or has been an officer of the corporation against a liability
incurred in such capacity, except to the extent expressly permitted by that
section. For the purposes of this section, an "officer" of a corporation
includes a director, secretary, executive officer or trustee of that
corporation.
 
     Pursuant to Section 241(2) of the Corporations Law, a corporation may
indemnify any person against a liability to another person (that is, excluding a
liability to the corporation itself or an affiliate), unless the liability
arises out of conduct involving a lack of good faith. Section 241(3) of the
Corporations Law also specifically permits a person to be indemnified against a
liability for legal costs and expenses incurred (i) in defending civil or
criminal proceedings in which judgment is given in favour of the person or in
which the person is acquitted, or (ii) in connection with an application in
relation to such proceedings in which the court grants relief to the person
under the Corporation Law.
 
     A corporation may purchase and maintain insurance on behalf of a person who
is or has been an officer of the corporation against liabilities incurred in
such capacity, but Section 241A(1) of the Corporations Law prohibits the
purchase of such insurance in respect of any liability arising from (i) improper
use by that person of inside information to gain an advantage for any person or
cause detriment to the corporation or (ii) any improper use of that person's
position to gain such advantage or cause such detriment. A corporation may,
however, insure such a person against a liability for legal costs and expenses
incurred in defending any civil or criminal proceedings.
 
     Article 111 of the Articles of Association of the Issuer provides that its
directors, secretaries, officers, employees and trustees shall be indemnified to
the extent permitted by the Corporations Law. Article 111 also provides that on
the authority of the directors, the Issuer may execute a documentary indemnity
in favor of any officer of the corporation and purchase insurance on behalf of
or in respect of officers of the Issuer against liability incurred in such
capacity.

                                  UNDERTAKINGS
 
     (a) Each of the undersigned registrants hereby undertakes:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:
 
             (i) To include any prospectus required by section 10(a)(3) of the
        Securities Act of 1933;
 
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in this registration statement;
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in this registration statement
        or any material change to such information in this registration
        statement; provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii)
        do not apply if the information required to be included in a
        post-effective amendment by those paragraphs is contained in periodic
        reports filed by the Company pursuant to Section 13 or Section 15(d) of
        the Securities Exchange Act of 1934 that are incorporated by reference
        in the registration statement.
 
          (2) that, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     herein, and the offering of such securities at that time shall be deemed to
     be the initial bona fide offering thereof.
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
          (4) That, for purposes of determining any liability under the
     Securities Act of 1933, each filing of the Company's annual report pursuant
     to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934
     (and, where applicable, each filing of an employee benefit plan's annual
     report pursuant to Section 15(d) of the Securities Exchange Act of 1934)
     that is incorporated by reference in this registration statement relating
     to the securities offered therein, shall be deemed to be a new registration
     statement relating to the securities offered herein, and the offering of
     such securities at that time shall be deemed to be the initial bona fide
     offering thereof.
 
          (5) That, for purposes of determining any liability under the
     Securities Act of 1933, the information omitted from the form of prospectus
     filed as part of this registration statement in reliance upon Rule 430A and
     contained in a form of prospectus filed by the registrant pursuant to Rule
     424(b)(1) or (4), or 497(h) under the Securities Act of 1933 shall be
     deemed to be part of this registration statement as of the time it was
     declared effective.
 
          (6) That, for the purpose of determining any liability under the
     Securities Act of 1933, each post-effective amendment that contains a form
     of prospectus shall be deemed to be a new registration statement relating
     to the securities offered therein, and the offering of such securities at
     that time shall be deemed to be the initial bona fide offering thereof.
 
     (b) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions of Article 15, or otherwise,
the registrants have been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act of 1933 and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by a registrant of expenses incurred or paid by a director, officer or
controlling person of such registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrants will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by them is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.

                             APACHE FINANCE PTY LTD


                                Debt Securities


                        Guaranteed by Apache Corporation



                       UNDERWRITING AGREEMENT BASIC TERMS


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

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





<PAGE>   3
Exhibit A hereto and such other terms as are agreed by the Company and the
Underwriters.  In addition, each Terms Agreement shall specify whether the
Company has agreed to grant to the Underwriters an option to purchase
additional Offered Securities to cover over-allotments, if any, and the amount
of Offered Securities subject to such option (the "Option Securities").  As
used herein, the term "Offered Securities" shall include the Option Securities,
if any, and "Representatives" shall mean the Underwriter or Underwriters so
specified in the Terms Agreement or, if no Underwriter is so specified, shall
mean each Underwriter.  The Terms Agreement may be in the form of an exchange
of any standard form of written telecommunication between the Underwriters and
the Company.  The offering of the Offered Securities will be governed by the
Terms Agreement, as supplemented hereby (collectively, this "Agreement"), and
this Agreement shall inure to the benefit of and be binding upon each
Underwriter participating in the offering of the Offered Securities.

         The Company and the Guarantor have prepared and filed with the
Securities and Exchange Commission (the "Commission") a registration statement
on Form S-3 (No. 333-________) for the registration of Debt Securities,
including the Offered Securities and the Guarantee, under the Securities Act of
1933, as amended (the "1933 Act"), and the offering thereof from time to time
in accordance with Rule 415 of the rules and regulations of the Commission
under the 1933 Act (the "1933 Act Regulations"), and have prepared and filed
such amendments thereto as may have been required to the date hereof.  Such
registration statement, as amended, has been declared effective by the
Commission, and the Indenture has been qualified under the Trust Indenture Act
of 1939 (the "1939 Act").  As provided in Section 3(a), a prospectus supplement
reflecting the terms of the Offered Securities, the terms of the offering
thereof and the other matters set forth therein has been prepared and will be
filed pursuant to Rule 424 under the 1933 Act.  Such prospectus supplement, in
the form first filed after the date of the Terms Agreement pursuant to Rule
424, is herein referred to as the "Prospectus Supplement".  Such registration
statement, as amended at the date of the Terms Agreement, including the
exhibits thereto and the documents incorporated by reference therein, is herein
called the "Registration Statement".  Any registration statement filed pursuant
to Rule 462(b) of the 1933 Act Regulations is herein referred to as the "Rule
462(b) Registration Statement," and after such filing the term "Registration
Statement" shall include the Rule 462(b) Registration Statement.  The basic
prospectus included in the Registration Statement relating to all offerings of
Debt Securities and the Guarantee under the Registration Statement, as
supplemented by the Prospectus Supplement, is herein called the "Prospectus",
except that, if such basic





                                       2
<PAGE>   4
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.

         SECTION 1.  Representations and Warranties.  The Company represents
and warrants as to matters relating to the Company and the Guarantor represents
and warrants as to matters relating to the Guarantor and its consolidated
subsidiaries, to each Underwriter named in the Terms Agreement as of the date
thereof and as of the Closing Time referred to in Section 2(c) hereof, and as
of each Date of Delivery (if any) referred to in Section 2(b) hereof (in each
case, a "Representation Date"), as follows:

                 (a)      The Company has been duly organized and is validly
         existing as a proprietary Company with limited liability under the laws
         of the Australian Capital Territory, Australia, with corporate power
         and authority to own, lease and operate its properties and conduct its
         business as described in the Prospectus, and to enter into and perform
         its obligations under this Agreement, the Offered Securities and the
         Indenture; and the Company is duly qualified as a 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 is an indirect wholly-owned consolidated subsidiary of the
         Guarantor and has no subsidiaries.

                 (b)      The Guarantor has been duly incorporated and is
         validly existing as a corporation in good standing under the





                                       3
<PAGE>   5
         laws of the State of Delaware, with 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 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, 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.

                 (c)  Each "significant subsidiary" of the Guarantor as defined
         in Rule 405 of Regulation C of the 1933 Act Regulations (collectively,
         the "Significant Subsidiaries") has been duly incorporated and is
         validly existing as a corporation in good standing under the laws of
         the jurisdiction of its incorporation, has corporate power and
         authority to own, lease and operate its properties and conduct its
         business as described in the Prospectus and is duly qualified as a
         foreign corporation to transact business and is in good standing in
         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, all of
         the issued and outstanding capital stock of each Significant
         Subsidiary has been duly authorized and validly issued, is fully paid
         and non-assessable and, except for directors' qualifying shares (if
         applicable), is owned by the Guarantor, directly or through
         subsidiaries, free and clear of any security interest, mortgage,
         pledge, lien, encumbrance, claim or equity.

                 (d)  At the time the Registration Statement and the Rule
         462(b) Registration Statement, if any, became effective and as of each
         Representation Date, the Registration Statement and the Rule 462(b)
         Registration Statement, if any, complied and will comply in all
         material respects with the requirements of the 1933 Act and the 1933
         Act Regulations and the 1939 Act and the rules and regulations of the
         Commission promulgated thereunder; the Registration Statement and the
         Rule 462(b) Registration Statement, if any, each at the time it became
         effective, did not, and at each





                                       4
<PAGE>   6
         time thereafter at which any amendment to the Registration Statement
         becomes effective or any Annual Report on Form 10-K is filed by the
         Guarantor with the Commission and as of each Representation Date, will
         not, contain an untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading; and the Prospectus, as of each
         Representation Date, does not and will not include an untrue statement
         of a material fact or omit to state a material fact necessary in order
         to make the statements therein, in the light of the circumstances
         under which they were made, not misleading; provided, however, that
         the representations and warranties in this subsection shall not apply
         to statements in or omissions from the Registration Statement and the
         Rule 462(b) Registration Statement, if any, or the Prospectus made in
         reliance upon and in conformity with information furnished to the
         Company or the Guarantor in writing by the Underwriters expressly for
         use in the Registration Statement and the Rule 462(b) Registration
         Statement, if any, or the Prospectus.

                 (e)  The documents incorporated by reference in the
         Prospectus, at the time they were or hereafter are filed with the
         Commission, complied or when so filed will comply, as the case may be,
         in all material respects with the requirements of the 1934 Act and the
         rules and regulations of the Commission promulgated thereunder (the
         "1934 Act Regulations"), and, when read together and with the other
         information in the Prospectus, did not and will not include an untrue
         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary in order to make the statements
         therein, in the light of the circumstances under which they were or
         are made, not misleading.

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

                 (g)  The financial statements and any supporting schedules of
         the Guarantor and its subsidiaries included or incorporated by
         reference in the Registration Statement and the Prospectus present
         fairly the consolidated financial position of the Guarantor and its
         subsidiaries as of the dates indicated and the consolidated results of
         their operations for the periods specified; except as stated therein,
         said financial statements have been prepared in





                                       5
<PAGE>   7
         conformity with U.S. generally accepted accounting principles applied
         on a consistent basis; the supporting schedules included or
         incorporated by reference in the Registration Statement and the
         Prospectus present fairly the information required to be stated
         therein; and the pro forma financial statements and the related notes
         thereto, if any, included or incorporated by reference in the
         Registration Statement and the Prospectuses present fairly the
         information shown therein, have been prepared in accordance with the
         Commission's rules and guidelines with respect to pro forma financial
         statements and have been properly compiled on the bases described
         therein, and the assumptions used in the preparation thereof are
         reasonable and the adjustments used therein are appropriate to give
         effect to the transactions and circumstances referred to therein.

                 (h)  The petroleum engineers who have consented to being named
         as having reviewed certain reserve data included or incorporated by
         reference in the Prospectus are independent engineers with respect to
         the Guarantor and its subsidiaries.

                 (i)  This Agreement and the applicable Delayed Delivery
         Contracts (as defined below), if any, have been duly authorized,
         executed and delivered by the Company and the Guarantor and, upon
         execution and delivery by the Underwriters, will be valid and legally
         binding agreements of the Company and the Guarantor; on and after the
         Closing Time, the Indenture will have been duly authorized, executed
         and delivered by the Company and the Guarantor and, assuming due
         execution and delivery by the Trustee, will be a valid and legally
         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 except further as
         enforcement thereof may be limited by (1) requirements that a claim
         with respect to any Debt Securities denominated other than in U.S.
         dollars (or a foreign currency or composite currency judgment in
         respect of such claim) be converted into U.S. dollars at a rate of
         exchange prevailing on a date determined pursuant to applicable law or
         (2) governmental authority to limit, delay or prohibit the making of
         payments outside the United States. The Offered Securities have been
         duly and validly authorized for issuance, offer and sale pursuant to
         this Agreement and each Delayed Delivery Contract, if any, and when
         issued, authenticated and delivered pursuant to the provisions of this
         Agreement and the Indenture against





                                       6
<PAGE>   8
         payment of the consideration therefor, the Offered Securities 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 laws relating to or affecting enforcement of
         creditors' rights generally or by general equity principles, and
         except further as enforcement thereof may be limited by (1)
         requirements that a claim with respect to any Offered Securities
         denominated other than in U.S. dollars (or a foreign currency or
         composite currency judgment in respect of such claim) be converted
         into U.S. dollars at a rate or exchange prevailing on a date
         determined pursuant to applicable law or (2) governmental authority to
         limit, delay or prohibit the making of payments outside the United
         States.  The Offered Securities and the Indenture, including the
         Guarantee, will be substantially in the form heretofore delivered to
         the Underwriters and conform in all material respects to all
         statements relating thereto contained in the Prospectus; and each
         Holder (as defined in the Indenture) of Offered Securities will be
         entitled to the benefits of the Indenture.

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

                 (k)  Since the respective dates as of which information is
         given in the Registration Statement, any Rule 462(b) Registration
         Statement and the Prospectus, except as may otherwise be stated
         therein or contemplated thereby, (1) there has been no material
         adverse change in the





                                       7
<PAGE>   9
         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 and (2) there have been no
         material transactions entered into by the Guarantor or any of its
         subsidiaries other than those in the ordinary course of business.

                 (l)  Neither the Guarantor nor any of its subsidiaries is in
         violation of its charter or in default in the performance or
         observance of any material obligation, agreement, covenant or
         condition contained in any contract, indenture, mortgage, loan
         agreement, note, lease or other instrument to which it is a party or
         by which it or any of them or their properties may be bound, where the
         consequences of such violation or default would have a material
         adverse effect on the condition, financial or otherwise, or the
         results of operations, business affairs or business prospects of the
         Company or the Guarantor and its subsidiaries considered as one
         enterprise; and the execution and delivery of this Agreement, each
         Delayed Delivery Contract, if any, and the Indenture and the
         consummation of the transactions contemplated herein and therein have
         been duly authorized by all necessary corporate action of the Company
         and the Guarantor and will not conflict with or constitute a breach
         of, or default under, or result in the creation or imposition of any
         lien, charge or encumbrance upon any property or assets of the
         Guarantor or any of its subsidiaries pursuant to, any contract,
         indenture, mortgage, loan agreement, note, lease or other instrument
         to which the Guarantor or any of its subsidiaries is a party or by
         which it or any of them may be bound or to which any of the property
         or assets of the Guarantor or any subsidiary thereof is subject, nor
         will such action result in any violation of the provisions of the
         charter or by-laws of the Company or the Guarantor or any law,
         administrative regulation or administrative or court order or decree,
         where the consequences of such conflict, breach, creation, imposition,
         violation or default would have a material adverse effect on the
         condition, financial or otherwise, or the results of operations,
         business affairs or business prospects of the Company or the Guarantor
         and its subsidiaries considered as one enterprise.

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

         may be, or as may be required under state securities laws ("Blue
         Sky").

                 (n)  Except as may be included or incorporated by reference in
         the Registration Statement and the Prospectus, there is no action,
         suit or proceeding before or by any court or governmental agency or
         body, domestic or foreign, now pending or, to the knowledge of the
         Company or the Guarantor, threatened against or affecting the
         Guarantor or any of its subsidiaries which might, in the opinion of
         the Company or the Guarantor, result in 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, or
         could reasonably be expected to materially and adversely affect the
         properties or assets thereof or could reasonably be expected to
         materially and adversely affect the consummation of this Agreement or
         the Indenture or any transaction contemplated hereby or thereby.

                 (o)  There are no contracts or documents of the Guarantor or
         any of its subsidiaries which are required to be filed as exhibits to
         the Registration Statement by the 1933 Act or by the 1933 Act
         Regulations which have not been so filed.

                 (p)  Neither the Guarantor nor any of its subsidiaries is in
         violation of any law, ordinance, governmental rule or regulation or
         court decree to which it may be subject or has failed to obtain any
         license, permit, franchise or other governmental authorization
         necessary to the ownership of its property or to the conduct of its
         business, which violation or failure 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 considered as one enterprise; and the Guarantor
         and its subsidiaries own or possess or have obtained all governmental
         licenses, permits, consents, orders, approvals and other
         authorizations and have properly filed with the appropriate
         authorities all notices, applications and other documents necessary to
         lease or own their respective properties and to carry on their
         respective businesses as 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 subsidiaries considered as one
         enterprise.

                 (q)  The Guarantor and its subsidiaries own or possess, or can
         acquire on reasonable terms, adequate trademarks, service marks and
         trade names necessary to conduct the business now 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 considered as one enterprise.

                 (r)  The Guarantor and its subsidiaries have legal, valid and
         defensible title to all of their interests in oil and gas properties
         and to all other real and personal property owned by them and any
         other real property and buildings held under 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, (2) liens and encumbrances under operating
         agreements, unitization and pooling agreements, production sales
         contracts, farm-out agreements and other oil and gas 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





                                       10
<PAGE>   12
         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,





                                       11
<PAGE>   13
         financial or otherwise, or the results of operations, business affairs
         or business prospects of the Company or the Guarantor and its
         subsidiaries considered as one enterprise.

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

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

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

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





                                       12
<PAGE>   14
         of the State of New York or of the United States located in the State
         of New York having jurisdiction under its own domestic laws in respect
         of any suit, action or proceeding against the Company based upon any
         instruments or agreements entered into for the consummation of the
         transactions contemplated herein would be declared enforceable against
         the Company by the courts of Australia without reexamination, review
         of the merits of the cause of action in respect of which the original
         judgment was given or relitigation of the matters adjudicated upon or
         payment of any stamp, registration or similar tax or duty, provided
         that (A) the judgment is consistent with public policy in Australia
         and any relevant political subdivision, (B) the judgment was not given
         or obtained by fraud or in a manner contrary to natural justice, (C)
         the judgment was not based on a clear mistake of law or fact, (D) the
         judgment was not directly or indirectly for the payment of taxes or
         other charges of a like nature or of a fine or other penalty, (E) the
         judgment is for a definite sum, and (F) there has been no prior
         judgment in another court between the same parties concerning the same
         issues as are dealt with in the judgment to be enforced in Australia.
         The Company is not aware of any reason why the enforcement in
         Australia of such a judgment in respect of any of the instruments or
         agreements executed for consummation of the transactions contemplated
         herein or in the Prospectus would be contrary to public policy in
         Australia or any political subdivision of either of them.

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





                                       13
<PAGE>   15
         Company has waived or will waive such right to the extent permitted by
         law and has consented to such relief and enforcement as provided in
         this Agreement and the Indenture.

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

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

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

         SECTION 2.  Purchase and Sale.

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





                                       14
<PAGE>   16
Contracts are herein sometimes referred to as "Immediate Delivery Offered
Securities".

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

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





                                       15
<PAGE>   17
in same day funds to the account specified in the Terms Agreement against
delivery to the Underwriters for the respective accounts of the Underwriters of
the Immediate Delivery Offered Securities to be purchased by them (unless the
Offered Securities are issuable only in the form of one or more global
instruments registered in the name of a depository or a nominee of a
depository, in which event the Underwriters' interest in such global instrument
shall be noted in a manner satisfactory to the Underwriters and their counsel).
In addition, in the event that any or all of the Option Securities are
purchased by the Underwriters, payment of the purchase price for, and delivery
of certificates representing, such Option Securities shall be made at such
place as shall be agreed upon by the Representatives and the Company, on each
Date of Delivery as agreed by the Representatives and the Company.  The
Immediate Delivery Offered Securities shall be in such denominations and
registered in such names as the Underwriters may request in writing at least
two business days prior to the Closing Time or relevant Date of Delivery, as
the case may be.  The Immediate Delivery Offered Securities, which if agreed by
the Representatives may be in temporary form, will be made available for
examination and packaging by the Representatives on or before the first
business day prior to the Closing Time or relevant Date of Delivery, as the
case may be.

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





                                       16
<PAGE>   18
         (e)     The Representatives are to submit to the Company, at least two
business days prior to the Closing Time, the names of any institutional
investors with which it is proposed that the Company will enter into Delayed
Delivery Contracts and the principal amount of Delayed Delivery Offered
Securities to be purchased by each of them, and the names of the institutions
with which the making of Delayed Delivery Contracts is approved by the Company
and the principal amount of Delayed Delivery Offered Securities to be covered
by each such Delayed Delivery Contract.

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

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

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

                 (b)      If at any time when the Prospectus is required by the

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

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

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

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





                                       18
<PAGE>   20
         Representatives immediately, and promptly confirm the notice in
         writing, of (i) the effectiveness of any amendment to the Registration
         Statement, (ii) the transmittal to the Commission for filing of any
         supplement to the Prospectus or any document to be filed pursuant to
         the 1934 Act which will be incorporated by reference into the
         Registration Statement or the Prospectus, (iii) the receipt of any
         comments from the Commission with respect to the Registration
         Statement, the Prospectus or the Prospectus Supplement, (iv) any
         request by the Commission for any amendment to the Registration
         Statement, or any amendment or supplement to the Prospectus or for
         additional information, (v) the issuance by the Commission of any stop
         order suspending the effectiveness of the Registration Statement or
         the initiation of any proceedings for that purpose and (vi) any change
         in the rating assigned by any nationally recognized statistical rating
         organization to any debt securities of the Company or the Guarantor or
         the public announcement by any nationally recognized statistical
         rating organization that it has under surveillance or review, with
         possible negative implications, its rating of any debt securities of
         the Company or the Guarantor.  The Company and the Guarantor will make
         every reasonable effort to prevent the issuance of any stop order and,
         if any stop order is issued, to obtain the lifting thereof at the
         earliest possible moment.

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

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





                                       19
<PAGE>   21
         to service of process or to qualify as a foreign corporation in any
         jurisdiction in which it is not so qualified.  The Company and the
         Guarantor will file such statements and reports as may be required by
         the laws of each jurisdiction in which the Offered Securities have
         been qualified as above provided.  The Company or the Guarantor will
         promptly advise the Representatives of the receipt by the Company of
         any notification with respect to the suspension of the qualification
         of the Offered Securities for sale in any such state or jurisdiction
         or the initiating or threatening of any proceeding for such purpose.

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

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





                                       21
<PAGE>   23
                 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
                 laws relating to or affecting enforcement of creditors' rights
                 generally or by general equity principles, and except further
                 as enforcement thereof may be limited by (1) requirements that
                 a claim with respect to any Debt Securities denominated other
                 than in U.S. dollars (or a foreign currency or composite
                 currency judgment in respect of such claim) be converted into
                 U.S. dollars at a rate of exchange prevailing on a date
                 determined pursuant to applicable law or (2) governmental
                 authority to limit, delay or prohibit the making of payments
                 outside the United States; and each holder of Offered
                 Securities will be entitled to the benefits of the Indenture.

                              (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





                                       22
<PAGE>   24
                 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 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





                                       23
<PAGE>   25
         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
                 prospects of the Guarantor and its subsidiaries considered as
                 one enterprise.

                             (iii)  Each Significant Subsidiary has been duly
                 incorporated and is validly existing as a corporation in good
                 standing under the laws of the jurisdiction of its
                 incorporation, has corporate power and authority to own, lease
                 and operate its properties and conduct its business as
                 described in the Prospectus, and, to the best of such
                 counsel's knowledge and information, is duly qualified as a
                 foreign corporation to transact business and is in good
                 standing in each 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 prospects of the
                 Guarantor and its subsidiaries considered as one enterprise;
                 and all of the issued and outstanding capital stock of each
                 Significant Subsidiary has been duly authorized and validly
                 issued, is fully paid and non-assessable, and is owned by the
                 Guarantor, directly or indirectly, free and clear of any
                 mortgage, pledge, lien, encumbrance, claim or equity (except
                 as described in the Prospectus).

                          (iv)  Each document filed pursuant to the 1934 Act
                 and incorporated by reference in the Prospectus (except for

                 or statistical information as to which no opinion need be

                 responsive when so filed to the requirements of the 1934 Act
                 and the 1934 Act Regulations.

                          (v)  Neither the Guarantor nor any of its

                 decree of any court or governmental authority or agency is
                 required that has not been obtained in connection with the
                 consummation by the Company or the Guarantor of the
                 transactions contemplated by this Agreement, any Delayed
                 Delivery Contract or the Indenture, except such as have been
                 obtained or rendered, as the case may be, or as may be

                 1934 Act, the 1934 Act Regulations or state securities laws;
                 and the execution and delivery of this Agreement, the Delayed
                 Delivery Contract, if applicable, and the Indenture and the
                 consummation of the transactions contemplated herein and
                 therein have been duly authorized by all necessary corporate
                 action of the Company and the Guarantor and, to the best
                 knowledge and information of such counsel, 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 Guarantor or any of its
                 subsidiaries pursuant to, any contract, indenture, mortgage,
                 loan agreement, note, lease or other instrument to which the
                 Guarantor or any of its subsidiaries is a party or by which it
                 or any of them may be bound or to which any of the property or
                 assets of the Guarantor or any such subsidiary is subject, nor
                 will such action result in any violation of the provisions of
                 the charter or by-laws of the Guarantor or any applicable law,
                 administrative regulation or, to the best knowledge and

                          (viii)  To the best knowledge and information of such
                 counsel, neither the Guarantor nor any of its subsidiaries is
                 in violation of any law, ordinance, governmental rule or
                 regulation or court decree to which it may be subject or has
                 failed to obtain any license, permit, franchise or other
                 governmental authorization necessary to the ownership of its
                 property or to the conduct of its business, which violation or
                 failure would materially adversely affect 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, to the best
                 knowledge and information of such counsel, the Guarantor and
                 its subsidiaries own or possess or have obtained all
                 governmental licenses, permits, consents, orders, approvals
                 and other authorizations necessary to lease or own their
                 respective properties and to carry on their respective
                 businesses as presently conducted, except where the failure to
                 obtain such authorizations 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.

                          (ix)  To the best of such counsel's knowledge and
                 information, there is no action, suit or proceeding before or
                 by any court or 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 in any material adverse change
                 in the condition, financial or otherwise, or in the results of
                 operations, business affairs or business prospects of the
                 Guarantor and its subsidiaries considered as one enterprise,
                 or would materially and adversely affect the properties or
                 assets thereof or would materially and adversely affect the
                 consummation of this Agreement, the Delayed Delivery
                 Contracts, if applicable, or the Indenture or any transaction
                 contemplated hereby or thereby.

                          (x)  To the best of such counsel's knowledge and
                 information, there are no contracts or other documents
                 required to be described or referred to in the Registration
                 Statement or to be filed as exhibits thereto other than those
                 described or referred to therein or filed or incorporated by
                 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





                                       26

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

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

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

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

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




                                     27

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

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

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

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

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




                                     28

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

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

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

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

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




                                     29
<PAGE>   31
                 having jurisdiction under its own domestic laws in respect of
                 any suit, action or proceeding against the Company based upon
                 any instruments or agreements entered into for the
                 consummation of the transactions contemplated in this
                 Agreement, the Indenture, or the Offered Securities would be
                 declared enforceable against the Company by the courts of
                 Australia without reexamination, review of the merits of the
                 cause of action in respect of which the original judgment was
                 given or relitigation of the matters adjudicated upon or
                 payment of any stamp, registration or similar tax or duty,
                 provided that (A) the judgment is consistent with public
                 policy in Australia and any relevant political subdivision,
                 (B) the judgment was not given or obtained by fraud or in a
                 manner contrary to natural justice, (C) the judgment was not
                 based on a clear mistake of law or fact, (D) the judgment was
                 not directly or indirectly for the payment of taxes or other
                 charges of a like nature or of a fine or other penalty, (E)
                 the judgment is for a definite sum, and (F) there has been no
                 prior judgment in another court between the same parties
                 concerning the same issues as are dealt with in the judgment
                 to be enforced in Australia.  Such counsel is not aware of any
                 reason why the enforcement in Australia of such a judgment in
                 respect of any of the instruments or agreements executed for
                 consummation of the transactions contemplated herein or in the
                 Prospectus would be contrary to public policy in Australia or
                 any political subdivision of either of them.

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




                                     30
<PAGE>   32
                 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

                 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

                 Australian exchange controls, and under the caption "Tax

                 information constitutes matters of law, summaries of legal

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

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

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




                                     32
<PAGE>   34
         supplement was issued or, at the Closing Time included or includes an
         untrue statement of a material fact or omitted or omits to state a
         material fact necessary in order to make the statements therein, in
         the light of the circumstances under which they were made, not
         misleading (it being understood that such counsel need express no
         opinion with respect to the financial statements and engineering
         reports and other financial or engineering data contained in the
         Registration Statement (including the Prospectus) or those parts of
         the Registration Statement which constitute the Form T-1).

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

<PAGE>   36
                 Prospectus do not comply as to form in all material respects
                 with the applicable accounting requirements of the 1934 Act
                 and the 1934 Act Regulations or (C) at a specified date not
                 more than three days prior to the date of such letter, there
                 was any change in the consolidated capital stock, any increase
                 in consolidated long-term debt or any decrease in the
                 consolidated net current assets or consolidated net assets of
                 the Guarantor and its subsidiaries, in each case as compared
                 with the amounts shown on the most recent consolidated balance
                 sheet of the Guarantor and its subsidiaries included or
                 incorporated by reference in the Registration Statement and
                 the Prospectus or, during the period from the date of such
                 balance sheet to a specified date not more than three days
                 prior to the date of such letter, there were any decreases, as
                 compared with the corresponding period in the preceding year,
                 in consolidated revenues or in the total or per-share amounts
                 of income before extraordinary items or of net income of the
                 Guarantor and its subsidiaries, except in all instances for
                 changes, increases or decreases that the Registration
                 Statement and the Prospectus disclose have occurred or may
                 occur or except for such exceptions enumerated in such letter
                 as shall have been agreed to by the Underwriters and the
                 Guarantor.

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

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




                                     35
<PAGE>   37
                 relevant accounting, financial and other records of the
                 Guarantor and its subsidiaries identified in such letter.

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

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

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

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

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

         counsel for the Underwriters, dated such Date of Delivery, relating to
         the Option Securities and otherwise substantially to the same effect
         as the opinions required by subsections (1), (2) and (3) of Section

         the Option Securities and otherwise to the same effect as the opinion
         required by subsections (4) and (5) to Section 4(b) hereof.

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

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

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

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




                                     39
<PAGE>   41
         body, commenced or threatened, or any claim whatsoever based upon any
         such untrue statement or omission, or any such alleged untrue
         statement or omission, to the extent that any such expense is not paid
         under (i) or (ii) above.

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

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




                                     40
<PAGE>   42
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 8 or Section 9 hereof (whether
or not the indemnified parties are actual or potential parties thereto), unless
such settlement, compromise or consent (i) includes an unconditional release of
each indemnified party from all liability arising out of such litigation,
investigation, proceeding or claim and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act by or on behalf of
any indemnified party.

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

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




                                     41
<PAGE>   43
received by the Company and the Guarantor on the one hand and the Underwriters
on the other hand in connection with the offering of the Offered Securities
pursuant to this Agreement shall be deemed to be in the same respective
proportions as the total net proceeds from the offering of the Offered
Securities pursuant to this Agreement (before deducting expenses) received by
the Company and the total commission or underwriting discount received by each
Underwriter, in each case as set forth on the cover of the Prospectus
Supplement, bear to the aggregate initial public offering price of the Offered
Securities sold to or through such Underwriter as set forth on such cover.  The
relative fault of the Company and the Guarantor on the one hand and the
Underwriters on the other hand shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or
the omission or alleged omission to state a material fact relates to
information supplied by the Company or the Guarantor or by the Underwriters and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.  The Company, the Guarantor
and the Underwriters agree that it would not be just and equitable if
contribution pursuant to this Section 7 were determined by pro rata allocation
(even if the Underwriters were treated as one entity for such purpose) or by
any other method of allocation which does not take account of the equitable
considerations referred to above in this Section 7.  The aggregate amount of
losses, liabilities, claims, damages and expenses incurred by an indemnified
party and referred to above in this Section 7 shall be deemed to include any
legal or other expenses reasonably incurred by such indemnified party in
investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged
untrue statement or omission or alleged omission.  Notwithstanding the
provisions of this Section 7, no Underwriter shall be required to contribute
any amount in excess of the amount by which the total price at which the
Offered Securities sold to or through such Underwriter were offered to the
public exceeds the amount of any damages which such Underwriter has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission.  No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the 1933 Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.  For purposes of this Section 7, each person, if any, who
controls an Underwriter within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act shall have the same rights to contribution as such
Underwriter, and each director of the Company or the Guarantor, each officer of
the Company or the Guarantor who signed the Registration Statement, and each
person, if any, who controls the




                                     42
<PAGE>   44
Company or the Guarantor within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act shall have the same rights to contribution as the
Company or the Guarantor, as the case may be.  The Underwriters' respective
obligations to contribute pursuant to this Section 7 are several in proportion
to the principal amount of Offered Securities sold to or through each
Underwriter and not joint.

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

         SECTION 9.  Termination.

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




                                     43
<PAGE>   45
denominated or payable, or (iv) the rating assigned by any nationally
recognized statistical rating organization to any debt securities of the
Company or the Guarantor as of the date of the Terms Agreement shall have been
lowered since that date or if any such rating organization shall have publicly
announced that it has under surveillance or review, with possible negative
implications, its rating of any debt securities of the Company or the
Guarantor, as the case may be, or (v) there shall have come to the attention of
the Representatives any facts that would cause them to reasonably believe that
the Prospectus, at the time it was required to be delivered to a purchaser of
the Offered Securities, included an untrue statement of a material fact or
omitted to state a material fact necessary in order to make the statements
therein, in light of the circumstances existing at the time of such delivery,
not misleading.  As used in this Section 9, the term "Prospectus" means the
Prospectus in the form first provided to the applicable Underwriter or
Underwriters for use in confirming sales of the related Offered Securities.

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

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

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




                                     44
<PAGE>   46
         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 provided in the Terms Agreement.  Notices to the Company shall be
directed to Apache Finance Pty Ltd, 256 St. George's Terrace, Level 3, Perth,
Western Australia, 6000, Australia, Attention:_________ with a copy to the
Guarantor.  Notices to the Guarantor shall be directed to Apache Corporation,
2000 Post Oak Boulevard, Suite 100, Houston, Texas 77056-4400, Attention:  Vice
President and Treasurer, with a copy to:  Mr. Ralph K. Miller, Jr., Woodard,
Hall & Primm, P.C., 7100 Texas Commerce Tower, Houston, Texas 77002.  Any party
to this Agreement may from time to time designate another address to receive
notice pursuant to this Agreement by notice duly given in accordance with the
terms of this Section 11.




                                     45
<PAGE>   47
         SECTION 12.  Parties.  This Agreement shall inure to the benefit of
and be binding upon the Underwriters, the Company and the Guarantor and their
respective successors.  Nothing expressed or mentioned in this Agreement is
intended or shall be construed to give any person, firm or corporation, other
than the parties hereto and their respective successors and the controlling
persons and officers and directors referred to in Sections 6 and 7 and their
heirs and legal representatives, any legal or equitable right, remedy or claim
under or in respect of this Agreement or any provision herein contained.  This
Agreement and all conditions and provisions hereof are intended to be for the
sole and exclusive benefit of the parties hereto and their respective
successors and said controlling persons and officers and directors and their
heirs and legal representatives, and for the benefit of no other person, firm
or corporation.  No purchaser of Offered Securities from any Underwriter shall
be deemed to be a successor by reason merely of such purchase.

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

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

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

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




                                     46
<PAGE>   48
         acknowledge for and on its behalf service of any and all legal
         process, summons, notices and documents that may be served in any
         action, suit or proceeding brought against the Company in any such
         United States federal or state court with respect to its obligations,
         liabilities or any other matter arising out of or in connection with
         this Agreement, the Guarantee or any Debt Securities and that may be
         made on such designee, appointee and agent in accordance with legal
         procedures prescribed for such courts.  If for any reason such
         designee, appointee and agent hereunder shall cease to be available to
         act as such, the Company agrees to designate a new designee, appointee
         and agent in The City of New York on the terms and for the purposes of
         this Section 14 reasonably satisfactory to each of the
         Representatives.  The Company further hereby irrevocably consents and
         agrees to the service of any and all legal process, summons, notices
         and documents in any such action, suit or proceeding against the
         Company by serving a copy thereof upon the relevant agent for service
         of process referred to in this Section 14 (whether or not the
         appointment of such agent shall for any reason prove to be ineffective
         or such agent shall accept or acknowledge such service) or by mailing
         copies thereof by registered or certified air mail, postage prepaid,
         to the Company at its address specified in or designated pursuant to
         this Agreement, with a copy (similarly mailed) to CT Corporation, 1633
         Broadway, New York, New York 10019.  The Company agrees that the
         failure of any such designee, appointee and agent to give any notice
         of such service to it shall not impair or affect in any way the
         validity of such service or any judgment rendered in any action or
         proceeding based thereon.  Nothing herein shall in any way be deemed
         to limit the ability of the holders of the Securities, the
         Underwriters and the other persons referred to in Section 12 to serve
         any such legal process, summons, notices and documents in any other
         manner permitted by applicable law or to obtain jurisdiction over the
         Company or bring actions, suits or proceedings against the Company in
         such other jurisdictions, and in such manner, as may be permitted by
         applicable law.  The Company hereby irrevocably and unconditionally
         waives, to the fullest extent permitted by law, any objection that it
         may now or hereafter have to the laying of venue of any of the
         aforesaid actions, suits or proceedings arising out of or in
         connection with this Agreement brought in the United States federal
         courts located in The City of New York or the courts of the State of
         New York located in The City of New York and hereby further
         irrevocably and unconditionally waives and agrees not to plead or
         claim in any such court that any such action, suit or proceeding
         brought in any such court has been brought in an inconvenient forum.




                                     47
<PAGE>   49
                 (c)  The provisions of this Section 14 shall survive any
         termination of this Agreement, in whole or in part.

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

         SECTION 16.  Jurisdictional Restrictions on Sale of Offered
Securities.  The Company, the Guarantor and the Underwriters agree 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 individuals resident in, the Commonwealth of Australia and (ii) no
documents in relation to an offer of Securities shall be distribution in
Australia or in or from a state or territory thereof.




                                     48
<PAGE>   50
[Each Underwriter further severally represents and agrees that it will not sell
any Offered Securities in circumstances where it knows or has reasonable
grounds to believe 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 an associate of the
Company.  For the purposes of this provision, associate has the meaning given
in Division 16F of the Income Tax Assessment Act 1936 (the "Tax Act") but on
the basis that sections 159GZC(i)(a)(ii), (i)(d)(i) of the Tax Act do not
apply.]

Securities, offer the Offered Securities purchased by it for sale in one or
more of the following manners:  [specify requirements of Section 128F,
paragraphs (a), (b), (c), and (d), in plain English]]

[Each Underwriter agrees to provide the Company, within 14 days of receipt of a
request from 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 (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.]

the Guarantor or any of their properties, assets or revenues may have or may
hereafter become entitled to, or have attributed to it, any right of immunity,
on the grounds of sovereignty or otherwise, from any legal action, suit or
proceeding, from the giving of any relief in any thereof, from set-off or
counterclaim, from the jurisdiction of any court, from service of process, from
attachment upon or prior to judgment, from attachment in aid of execution of
judgment, or from execution of judgment, or other legal process or proceeding
for the giving of any relief or for the enforcement of any judgment, in any
jurisdiction in which proceedings may at any time be commenced, with respect to
its obligations, liabilities or any other matter under or arising out of or in
connection with this Agreement (including the Terms Agreement), the Indenture
(including the Guarantee) or the Offered Securities, the Company and the
Guarantor hereby irrevocably and unconditionally waive, and agree not to plead
or claim, any such immunity and consent to such relief and enforcement.

         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.

<PAGE>   24
the Guarantor or the Company, as applicable, unless such counsel knows, or in

representations with respect to such matters are erroneous.

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


                 Section 104.     Acts of Holders.

                 (a)  Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by or pursuant to this Indenture to be
given or taken by Holders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Holders in person or
by an agent duly appointed in writing.  If, but only if, Securities of a series
are issuable as Bearer Securities, any request, demand, authorization,
direction, notice, consent, waiver or other action provided in or pursuant to
this Indenture to be given or taken by Holders of Securities of such series
may, alternatively, be embodied in and evidenced by the record of Holders of
Securities of such series voting in favor thereof, either in person or by
proxies duly appointed in writing, at any meeting of Holders of Securities of
such series duly called and held in accordance with the provisions of Article
Fifteen, or a combination of such instruments and any such record.  Except as
herein otherwise expressly provided, such action shall become effective when
such instrument or instruments or record or both are delivered to the Trustee
and, where it is hereby expressly required, to the Guarantor or the Company, as
the case may be.  Such instrument or instruments and any such record (and the
action embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of the Holders signing such instrument or instruments or so voting
at any such meeting.  Proof of execution of any such instrument or of a writing
appointing any such agent, or of the holding by any Person of a Security, shall
be sufficient for any purpose of this Indenture and (subject to Section 315 of
the Trust Indenture Act) conclusive in favor of the Trustee, the Guarantor or
the Company, and any agent of the Trustee or the Company or the Guarantor, if
made in the manner provided in this Section.  The record of any meeting of
Holders of Securities shall be proved in the manner provided in Section 1406.

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

                 The Trustee shall fix a record date for the purpose of
determining the Persons who are beneficial owners of interest in any permanent
global Security held by a U.S. Depository





                                       15
<PAGE>   25
entitled under the procedures of such U.S. Depository to make, give or take, by
a proxy or proxies duly appointed in writing, any request, demand,
authorization, direction, notice, consent, waiver or other Act provided in or
pursuant to this Indenture to be made, given or taken by Holders.  If such a
record date is fixed, the Holders on such record date or their duly appointed
proxy or proxies, and only such Persons, shall be entitled to make, give or
take such request, demand, authorization, direction, notice, consent, waiver or
other Act, whether or not such Holders remain Holders after such record date.
No such request, demand, authorization, direction, notice, consent, waiver or
other Act shall be valid or  effective if made, given or taken more than 90
days after such record date.

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

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

                 (d)  The ownership, principal amount and serial numbers of
Bearer Securities held by any Person, and the date of the commencement and the
date of the termination of holding the same, may be proved by the production of
such Bearer Securities or by a certificate executed, as depositary, by any
trust company, bank, banker or other depositary reasonably acceptable to the
Trustee, the Guarantor and the Company, wherever situated, if such certificate
shall be deemed by the Company, the Guarantor, and the Trustee to be
satisfactory, showing that at the date therein mentioned such Person had on
deposit with such depositary, or exhibited to it, the Bearer Securities therein
described; or such facts may be proved by the certificate or affidavit of the
Person holding such Bearer Securities, if such certificate or affidavit is
deemed by the Company and the Trustee to be satisfactory.  The Trustee, the
Company and the Guarantor may assume that such ownership of any Bearer Security
continues until (1) another certificate or affidavit bearing a later date
issued in respect of the same Bearer Security is produced, or (2) such Bearer
Security is produced to the Trustee by some other Person, or (3) such Bearer
Security is surrendered in exchange for a Registered Security, or (4) such
Bearer Security is no longer Outstanding.  The ownership, principal amount and
serial numbers of Bearer Securities held by the Person so executing such
instrument or writing and the date of the commencement and the date of the
termination of holding the same may also be proved in any other manner which
the Trustee, the Guarantor and the Company deem sufficient.

                 (e)  If the Company or the Guarantor shall solicit from the
Holders of any Registered Securities any request, demand, authorization,
direction, notice, consent, waiver or other Act, the Company may at its option
(but is not obligated to), by Board Resolution, fix in advance a record date
for the determination of Holders of Registered Securities entitled to give such
request, demand, authorization, direction, notice, consent, waiver or other
Act.  If such a





                                       16
<PAGE>   26
record date is fixed, such request, demand, authorization, direction, notice,
consent, waiver or other Act may be given before or after such record date, but
only the Holders of Registered Securities of record at the close of business on
such record date shall be deemed to be Holders for the purpose of determining
whether Holders of the requisite proportion of Outstanding Securities have
authorized or agreed or consented to such request, demand, authorization,
direction, notice, consent, waiver or other Act, and for that purpose the
Outstanding Securities shall be computed as of such record date; provided that
no such authorization, agreement or consent by the Holders of Registered
Securities shall be deemed effective unless it shall become effective pursuant
to the provisions of this Indenture not later than six months after the record
date.

                 (f)  Any request, demand, authorization, direction, notice,
consent, waiver or other Act by the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done or suffered to be done by the Trustee, any Security
Registrar, any Paying Agent or the Company or the Guarantor in reliance
thereon, whether or not notation of such Act is made upon such Security.


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

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

                 (a)  the Trustee by any Holder, the Guarantor or the Company
         shall be sufficient for every purpose hereunder if made, given,
         furnished or filed in writing to or with the Trustee at its Corporate
         Trust Office, Attention: Corporate Trustee Administration Department,
         or

                 (b) the Guarantor or the Company by the Trustee or any Holder
         shall be sufficient for every purpose hereunder (unless otherwise
         herein expressly provided) if in writing and mailed, first-class
         postage prepaid, to the Guarantor or the Company, as applicable,
         addressed to the attention of its Treasurer at the address of its
         principal office specified in the first paragraph of this instrument
         or at any other address previously furnished in writing to the
         Trustee, the Guarantor or the Company, as applicable.


                 Section 106.     Notice to Holders of Securities; Waiver.

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





                                       17
<PAGE>   27
                 (a)  such notice shall be sufficiently given to Holders of
         Registered Securities if in writing and mailed, first-class postage
         prepaid, to each Holder of a Registered Security affected by such
         event, at his address as it appears in the Security Register, not
         later than the latest date, and not earlier than the earliest date,
         prescribed for the giving of such notice; and

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

                 In any case where notice to Holders of Registered Securities
is given by mail, neither the failure to mail such notice, nor any defect in
any notice so mailed, to any particular Holder of a Registered Security shall
affect the sufficiency of such notice with respect to other Holders of
Registered Securities or the sufficiency of any notice to Holders of Bearer
Securities given as provided herein.  Any notice which is mailed in the manner
herein provided shall be conclusively presumed to have been duly given or
provided.  In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by
mail, then such notification as shall be made with the approval of the Trustee
shall constitute a sufficient notification for every purpose hereunder.

                 In case by reason of the suspension of publication of any
Authorized Newspaper or Authorized Newspapers or by reason of any other cause
it shall be impracticable to publish any notice to Holders of Bearer Securities
as provided above, then such notification to Holders of Bearer Securities as
shall be given with the approval of the Trustee shall constitute sufficient
notice to such Holders for every purpose hereunder.  Neither failure to give
notice by publication to Holders of Bearer Securities as provided above, nor
any defect in any notice so published, shall affect the sufficiency of any
notice mailed to Holders of Registered Securities as provided above.

                 Where this Indenture provides for notice in any manner, such
notice may be waived in writing by the Person entitled to receive such notice,
either before or after the event, and such  waiver shall be the equivalent of
such notice.  Waivers of notice by Holders of Securities shall be filed with
the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

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


                 Section 108.     Conflict with Trust Indenture Act.

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


                 Section 109.     Effect of Headings and Table of Contents.

due in respect of the principal of, or premium or interest, if any, or
Additional Amounts on the Securities of any series (the "Required Currency")
into a currency in which a judgment will be rendered (the "Judgment Currency"),

shall not be discharged or satisfied by any tender, or any recovery pursuant to
any judgment (whether or not entered in accordance with clause (a)), in any
currency other than the Required Currency, except to the extent that such
tender or recovery shall result in the actual receipt, by the payee, of the
full amount of the Required Currency expressed to be payable in respect of such
payments, (ii) shall





                                       20
<PAGE>   30
be enforceable as an alternative or additional cause of action for the purpose
of recovering in the Required Currency the amount, if any, by which such actual
receipt shall fall short of the full amount of the Required Currency so
expressed to be payable and (iii) shall not be affected by judgment being
obtained for any other sum due under this Indenture.  For purposes of the
foregoing, "New York Banking Day" means any day except a Saturday, Sunday or a
legal holiday in The City of New York or a day on which banking institutions in
The City of New York are authorized or obligated by law, regulation or
executive order to be closed.

                 Section 202. Guarantee by Guarantor:  Form of Guarantee.

         The Guarantor by its execution of this Indenture hereby agrees with
each Holder of a Security authenticated and delivered by the Trustee, and with
the Trustee on behalf of each such Holder, to be unconditionally bound by the
terms and provisions of the Guarantee set forth below and authorizes the
Chairman of the Board, President or Vice President or the





                                       21
<PAGE>   31
Treasurer of the Guarantor to execute, manually or by facsimile signature in

Holder of each such Security by its execution and delivery of each such
Security, with such Guarantee endorsed thereon, authenticated and delivered by
the Trustee. When delivered pursuant to the provisions of Section 303 hereof,
the Guarantee so set forth on the Security shall bind the Guarantor
notwithstanding the fact that such Guarantee does not bear the signature of the
Guarantor.

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

GUARANTEE

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

         The Guarantor hereby agrees that its obligations hereunder shall be as
         if it were principal debtor and not merely surety, and shall be
         absolute and unconditional, irrespective of, and shall be unaffected
         by, any invalidity, irregularity or unenforceability of such Security
         or such Indenture, any failure to enforce the provisions of such
         Security or such Indenture, or any waiver, modification or indulgence
         granted to the Company with respect thereto, by the holder of such
         Security or the Trustee or any other circumstance which may otherwise
         constitute a legal or equitable discharge of a surety or guarantor.
         The Guarantor hereby waives the benefits of division and discussion,
         diligence, presentment, demand of payment, filing of claims with a
         court in the event of





                                      22
<PAGE>   32
         merger, insolvency or bankruptcy of the Company, any right to require
         a proceeding first against the Company, protest or notice with respect
         to such Security or the indebtedness evidenced thereby and all demands
         whatsoever, and covenants that this Guarantee will not be discharged
         except by strict and complete performance of the obligations contained
         in such Security and this Guarantee. The Guarantor hereby agrees that,
         in the event of a default in payment of principal of, premium, if any,
         and interest on, and any Additional Amounts with respect to, such
         Security, or default in any sinking fund or analogous payment referred
         to therein, legal proceedings may be instituted by the Trustee on
         behalf of, or by, the Holder of such Security, on the terms and
         conditions set forth in the Indenture, directly against the Guarantor
         to enforce this Guarantee without first proceeding against the
         Company.

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

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

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

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

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

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

         upon which and the manner in which such amounts shall be determined

         Default or covenants are consistent with the Events of Default or
         covenants set forth herein;

                 (q) if either or both of Section 402(2) relating to defeasance
         or Section 402(3) relating to covenant defeasance shall not be
         applicable to the Securities of such series, or any covenants in
         addition to those specified in Section 402(3) relating to the
         Securities of such series shall be subject to covenant defeasance, and
         any deletions from, or modifications or additions to, the provisions
         of Article Four in respect of the Securities of such series;

                 (r) if any of such Securities are to be issuable upon the
         exercise of warrants, and the time, manner and place for such
         Securities to be authenticated and delivered;

         form and are to be issuable in definitive form (whether upon original
         issue or upon exchange of a temporary Security) only upon receipt of
         certain certificates or other documents or satisfaction of other
         conditions, then the form and terms of such certificates, documents or

         Purchase Price; and

                 (v) any other terms of such Securities and any deletions from
         or modifications or additions to this Indenture in respect of such
         Securities.

                 All Securities (and Guarantees endorsed thereon) of any one
series and all Coupons, if any, appertaining to Bearer Securities of such
series shall be substantially identical except as to





                                       28
<PAGE>   38
Currency of payments due thereunder, denomination and the rate of interest, or
method of determining the rate of interest, if any, Maturity, and the date from
which interest, if any, shall accrue and except as may otherwise be provided by
the Company in or pursuant to the Board Resolution and set forth in the
Officers' Certificate or in any indenture or indentures supplemental hereto
pertaining to such series of Securities.  The terms of the Securities of any
series may provide, without limitation, that the Securities shall be
authenticated and delivered by the Trustee on original issue from time to time
upon telephonic or written order of persons designated in the Officers'
Certificate or supplemental indenture (telephonic instructions to be promptly
confirmed in writing by such person) and that such persons are authorized to
determine, consistent with such Officers' Certificate or any applicable
supplemental indenture, such terms and conditions of the Securities of such
series as are specified in such Officers' Certificate or supplemental
indenture.  All Securities of any one series need not be issued at the same
time and, unless otherwise so provided by the Company, a series may be reopened
for issuances of additional Securities of such series or to establish
additional terms of such series of Securities.

                 If any of the terms of the Securities of any series shall be
established by action taken by or pursuant to a Board Resolution, the Board
Resolutions of the Company and the Guarantor shall be delivered to the Trustee
at or prior to the delivery of the Officers' Certificate setting forth the
terms of such series.


                 Section 302.     Currency; Denominations.

                 Unless otherwise provided in or pursuant to this Indenture,
the principal of, any premium and interest on and any Additional Amounts with
respect to the Securities shall be payable in Dollars.  Unless otherwise
provided in or pursuant to this Indenture, Registered Securities denominated in
Dollars shall be issuable in registered form without Coupons in denominations
of $1,000 and any integral multiple thereof, and the Bearer Securities
denominated in Dollars shall be issuable in the denomination of $5,000.
Securities not denominated in Dollars shall be issuable in such denominations
as are established with respect to such Securities in or pursuant to this
Indenture.


                 Section 303.     Execution, Authentication, Delivery and
                                  Dating.

                 Securities shall be executed on behalf of the Company by its
Chairman of the Board, one of its Vice Chairmen, its President, its Treasurer,
one of its Assistant Treasurers or one of its Vice Presidents under its
corporate seal reproduced thereon and attested by its Secretary or one of its
Assistant Secretaries.  Coupons shall be executed on behalf of the Company by
the Treasurer, one of its Vice Presidents or any Assistant Treasurer of the
Company.  The signature of any of these officers on the Securities or any
Coupons appertaining thereto may be manual or facsimile.





                                       29
<PAGE>   39
                 Securities, and Guarantees and any Coupons appertaining
thereto, bearing the manual or facsimile signatures of individuals who were at
any time the proper officers of the Company or the Guarantor, as the case may
be, shall bind the Company and the Guarantor, respectively, notwithstanding
that such individuals or any of them have ceased to hold such offices prior to
the authentication and delivery of such Securities, Guarantees or Coupons or
did not hold such offices at the date of such Securities, Guarantees or
Coupons.

                 At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Securities, together with
any Coupons appertaining thereto, executed by the Company, Guarantees, endorsed
thereon by the Guarantor to the Trustee for authentication and, provided that
the Board Resolutions and Officers' Certificates or supplemental indenture or
indentures with respect to such Securities referred to in Section 301 and a
Company and the Guarantor Orders for the authentication and delivery of such
Securities and a Guarantor Order approving the delivery of the Guarantees
endorsed thereon have been delivered to the Trustee, the Trustee in accordance
with the Company Order and subject to the provisions hereof and of such
Securities shall authenticate and deliver such Securities having such
Guarantees.  In authenticating such Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities and any
Coupons appertaining thereto, and the Guarantees endorsed thereon, the Trustee
shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of
the Trust Indenture Act) shall be fully protected in relying upon,

                 (1)      an Opinion of Counsel to the effect that:

                 (a)      the form or forms and terms of such Securities and
         Coupons, if any, and Guarantees have been established in conformity
         with the provisions of this Indenture;

                 (b)      all conditions precedent to the authentication and
         delivery of such Securities and Coupons, if any, appertaining thereto,
         have been complied with and that such Securities and Coupons, when
         completed by appropriate insertions, executed under the Company's
         corporate seal and attested by duly authorized officers of the
         Company, delivered by duly authorized officers of the Company to the
         Trustee for authentication pursuant to this Indenture, and
         authenticated and delivered by the Trustee and issued by the Company
         in the manner and subject to any conditions specified in such Opinion
         of Counsel, will constitute legally valid and binding obligations of
         the Company, enforceable against the Company in accordance with their
         terms, except as enforcement thereof may be subject to or limited by
         bankruptcy, insolvency, reorganization, moratorium, arrangement,
         fraudulent conveyance, fraudulent transfer or other similar laws
         relating to or affecting creditors' rights generally, and subject to
         general principles of equity (regardless of whether enforcement is
         sought in a proceeding in equity or at law) and will entitle the
         Holders thereof to the benefits of this Indenture, including the
         Guarantee; such Opinion of Counsel need express no opinion as to the
         availability of equitable remedies;





                                       30
<PAGE>   40
                 (c)      the Guarantees, when executed under the Guarantor's
         corporate seal and attested by duly authorized officers of the
         Guarantor, delivered by duly authorized officers of the Guarantor and
         issued by the Guarantor in the manner and subject to any condition
         specified in such Opinion of Counsel, will constitute legally valid
         and binding obligations of the Guarantor, enforceable against the
         Guarantor in accordance with its terms, except as enforcement thereof
         may be subject to or limited by bankruptcy, insolvency,
         reorganization, moratorium, arrangement, fraudulent conveyance,
         fraudulent transfer or other similar laws relating to or affecting
         creditors' rights generally, and subject to general principles of
         equity (regardless of whether enforcement is sought in a proceeding in
         equity or at law) and will entitle the Holders to the benefits of this
         Indenture; such Opinion of Counsel need express no opinion as to the
         availability of equitable remedies;

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

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

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

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

                 The Trustee shall not be required to authenticate or to cause
an Authenticating Agent to authenticate any Securities if the issue of such
Securities pursuant to this Indenture will affect the Trustee's own rights,
duties or immunities under the Securities and this Indenture or otherwise in a
manner which is not reasonably acceptable to the Trustee or if the Trustee,
being advised by counsel, determines that such action may not lawfully be
taken.

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

                 No Security, Guarantee or Coupon appertaining thereto shall be
entitled to any benefit under this Indenture or be valid or obligatory for any
purpose, unless there appears on such





                                       31
<PAGE>   41
Security a certificate of authentication substantially in the form provided for
in Section 202 or 611 executed by or on behalf of the Trustee or by the
Authenticating Agent by the manual signature of one of its authorized officers.
Such certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder.  Except as permitted by Section 306 or 307, the Trustee shall not
authenticate and deliver any Bearer Security or related Guarantee unless all
Coupons appertaining thereto then matured have been detached and canceled.


                 Section 304.     Temporary Securities.

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

                 Except in the case of temporary Securities in global form,
which shall be exchanged in accordance with the provisions thereof, if
temporary Securities are issued, the Company shall cause definitive Securities
to be prepared without unreasonable delay.  After the preparation of definitive
Securities of the same series and containing terms and provisions that are
identical to those of any temporary Securities, such temporary Securities shall
be exchangeable for such definitive Securities with Guarantees of the Guarantor
endorsed thereon  upon surrender of such temporary Securities at an Office or
Agency for such Securities, without charge to any Holder thereof.  Upon
surrender for cancellation of any one or more temporary Securities (accompanied
by any unmatured Coupons appertaining thereto), the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like
principal amount of definitive Securities of authorized denominations of the
same series and containing identical terms and provisions that the Guarantees
of the Guarantor have been endorsed thereon; provided, however, that no
definitive Bearer Security, except as provided in or pursuant to this
Indenture, shall be delivered in exchange for a temporary Registered Security;
and provided, further, that a definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security only in compliance with the conditions
set forth in or pursuant to this Indenture.  Unless otherwise provided in or
pursuant to this Indenture with respect to a temporary global Security, until
so exchanged the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.

                 Section 305.     Registration, Transfer and Exchange.

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

                 Upon surrender for registration of transfer of any Registered
Security of any series at any Office or Agency for such series, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Registered Securities
of the same series denominated as authorized in or pursuant to this Indenture,
of a like aggregate principal amount bearing a number not contemporaneously
outstanding and containing identical terms and provisions, having endorsed
thereon Guarantees duly authorized by the Guarantor.

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

                 If provided in or pursuant to this Indenture, with respect to
Securities of any series, at the option of the Holder, Bearer Securities of
such series may be exchanged for Registered Securities of such series
containing identical terms, denominated as authorized in or pursuant to this
Indenture and in the same aggregate principal amount, upon surrender of the
Bearer Securities to be exchanged at any Office or Agency for such series, with
all unmatured Coupons and all matured Coupons in default thereto appertaining.
If the Holder of a Bearer Security is unable to produce any such unmatured
Coupon or Coupons or matured Coupon or Coupons in default, such exchange may be
effected if the Bearer Securities are accompanied by payment in funds
acceptable to the Company, the Guarantor and the Trustee in an amount equal to
the face amount of such





                                       33
<PAGE>   43
missing Coupon or Coupons, or the surrender of such missing Coupon or Coupons
may be waived by the Company, the Guarantor and the Trustee if there is
furnished to them such security or indemnity as they may require to save each
of them and any Paying Agent harmless.  If thereafter the Holder of such Bearer
Security shall surrender to any Paying Agent any such missing Coupon in respect
of which such a payment shall have been made, such Holder shall be entitled to
receive the amount of such payment; provided, however, that, except as
otherwise provided in Section 1002, interest represented by Coupons shall be
payable only upon presentation and surrender of those Coupons at an Office or
Agency for such series located outside the United States.  Notwithstanding the
foregoing, in case a Bearer Security of any series is surrendered at any such
Office or Agency for such series in exchange for a Registered Security of such
series and like tenor after the close of business at such Office or Agency on
(i) any Regular Record Date and before the opening of business at such Office
or Agency on the relevant Interest Payment Date, or (ii) any Special Record
Date and before the opening of business at such Office or Agency on the related
date for payment of Defaulted Interest, such Bearer Security shall be
surrendered without the Coupon relating to such Interest Payment Date or
proposed date of payment, as the case may be (or, if such Coupon is so
surrendered with such Bearer Security, such Coupon shall be returned to the
Person so surrendering the Bearer Security), and interest or Defaulted
Interest, as the case may be, shall not be payable on such Interest Payment
Date or proposed date for payment, as the case may be, in respect of the
Registered Security issued in exchange for such Bearer Security, but shall be
payable only to the Holder of such Coupon when due in accordance with the
provisions of this Indenture.

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

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

                 Notwithstanding the foregoing, except as otherwise provided in
or pursuant to this Indenture, any global Security shall be exchangeable for
definitive Securities only if (i) the Depository is at any time unwilling,
unable or ineligible to continue as Depository and a successor depository is
not appointed by the Company within 90 days of the date the Company is so
informed in writing, (ii) the Company executes and delivers to the Trustee a
Company Order to the effect that such global Security shall be so exchangeable,
or (iii) an Event of Default has occurred and is continuing with respect to the
Securities.  If the beneficial owners of interests in a global Security are
entitled to exchange such interests for definitive Securities as the result of
an event described in clause (i), (ii) or (iii) of the preceding sentence, then
without unnecessary delay but in any event not later than the earliest date on
which such interests may be so exchanged, the Company shall deliver to the
Trustee definitive Securities in such form and denominations as





                                       34
<PAGE>   44
are required by or pursuant to this Indenture, and of the same series,
containing identical terms and in aggregate principal amount equal to the
principal amount of such global Security, executed by the Company.  On or after
the earliest date on which such interests may be so exchanged, such global
Security shall be surrendered from time to time by the U.S.  Depository or such
other Depository as shall be specified in the Company Order with respect
thereto, and in accordance with instructions given to the Trustee and the U.S.
Depository or such other Depository, as the case may be (which instructions
shall be in writing but need not be contained in or accompanied by an Officers'
Certificate or be accompanied by an Opinion of Counsel), as shall be specified
in the Company Order with respect thereto to the Trustee, as the Company's
agent for such purpose, to be exchanged, in whole or in part, for definitive
Securities as described above without charge.  The Trustee shall authenticate
and make available for delivery, in exchange for each portion of such
surrendered global Security, a like aggregate principal amount of definitive
Securities of the same series of authorized denominations and of like tenor as
the portion of such global Security to be exchanged, which (unless such
Securities are not issuable both as Bearer Securities and as Registered
Securities, in which case the definitive Securities exchanged for the global
Security shall be issuable only in the form in which the Securities are
issuable, as provided in or pursuant to this Indenture) shall be in the form of
Bearer Securities or Registered Securities, or any combination thereof, as
shall be specified by the beneficial owner thereof, but subject to the
satisfaction of any certification or other requirements to the issuance of
Bearer Securities; provided, however, that no such exchanges may occur during a
period beginning at the opening of business 15 days before any selection of
Securities of the same series to be redeemed and ending on the relevant
Redemption Date; and provided, further, that (unless otherwise provided in or
pursuant to this Indenture) no Bearer Security delivered in exchange for a
portion of a global Security shall be mailed or otherwise delivered to any
location in the United States.  Promptly following any such exchange in part,
such global Security shall be returned by the Trustee to such Depository or the
U.S. Depository, as the case may be, or such other Depository or U.S.
Depository referred to above in accordance with the instructions of the Company
referred to above.  If a Registered Security is issued in exchange for any
portion of a global Security after the close of business at the Office or
Agency for such Security where such exchange occurs on or after (i) any Regular
Record Date for such Security and before the opening of business at such Office
or Agency on the next Interest Payment Date, or (ii) any Special Record Date
for such Security and before the opening of business at such Office or Agency
on the related proposed date for payment of interest or Defaulted Interest, as
the case may be, interest shall not be payable on such Interest Payment Date or
proposed date for payment, as the case may be, in respect of such Registered
Security, but shall be payable on such Interest Payment Date or proposed date
for payment, as the case may be, only to the Person to whom interest in respect
of such portion of such global Security shall be payable in accordance with the
provisions of this Indenture.

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





                                       35
<PAGE>   45
                 Every Registered Security presented or surrendered for
registration of transfer or for exchange or redemption shall (if so required by
the Company or the Security Registrar for such Security) be duly endorsed, or
be accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar for such Security duly executed by the
Holder thereof or his attorney duly authorized in writing.

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

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


                 Section 306.     Mutilated, Destroyed, Lost and Stolen
                                  Securities.

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

                 If there be delivered to the Company, the Guarantor and to the
Trustee (i) evidence to their satisfaction of the destruction, loss or theft of
any Security or Coupon, and (ii) such security or indemnity as may be required
by them to save each of them and any agent of either of them harmless, then, in
the absence of notice to the Company, the Guarantor or the Trustee that such
Security or Coupon has been acquired by a bona fide purchaser, the Company
shall execute and, upon Company Request the Trustee shall authenticate and
deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Security or in exchange for the Security to which





                                       36
<PAGE>   46
a destroyed, lost or stolen Coupon appertains with all appurtenant Coupons not
destroyed, lost or stolen, a new Security of the same series containing
identical terms and of like principal amount having endorsed thereon the
Guarantee of the Guarantor and bearing a number not contemporaneously
outstanding, with Coupons corresponding to the Coupons, if any, appertaining to
such destroyed, lost or stolen Security or to the Security to which such
destroyed, lost or stolen Coupon appertains.

                 Notwithstanding the foregoing provisions of this Section 306,
in case any mutilated, destroyed, lost or stolen Security or Coupon has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security or Coupon; provided,
however, that principal of, any premium or interest on or any Additional
Amounts with respect to any Bearer Securities shall, except as otherwise
provided in Section 1002, be payable only at an Office or Agency for such
Securities located outside the United States and, unless otherwise provided in
or pursuant to this Indenture, any interest on Bearer Securities and any
Additional Amounts with respect to such interest shall be payable only upon
presentation and surrender of the Coupons appertaining thereto.

                 Upon the issuance of any new Security under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

                 Every new Security, with any Coupons appertaining thereto, and
the Guarantee of the Guarantor endorsed thereon, issued pursuant to this
Section in lieu of any destroyed, lost or stolen Security, or in exchange for a
Security to which a destroyed, lost or stolen Coupon appertains shall
constitute a separate obligation of the Company and the Guarantor,
respectively, whether or not the destroyed, lost or stolen Security and Coupons
appertaining thereto or the destroyed, lost or stolen Coupon shall be at any
time enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities of such
series and any Coupons and related Guarantees duly issued hereunder.

                 The provisions of this Section, as amended or supplemented
pursuant to this Indenture with respect to particular Securities or generally,
shall be exclusive and shall preclude (to the extent lawful) all other rights
and remedies with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities or Coupons.


                 Section 307.     Payment of Interest and Certain Additional 
                                  Amounts; Rights to Interest and Certain 
                                  Additional Amounts Preserved.

                 Unless otherwise provided in or pursuant to this Indenture,
any interest on and any Additional Amounts with respect to any Registered
Security which shall be payable, and are punctually paid or duly provided for,
on any Interest Payment Date shall be paid to the Person in





                                       37
<PAGE>   47
whose name such Security (or one or more Predecessor Securities) is registered
as of the close of business on the Regular Record Date for such interest.
Unless otherwise provided in or pursuant to this Indenture, in case a Bearer
Security is surrendered in exchange for a Registered Security after the close
of business at an Office or Agency for such Security on any Regular Record Date
therefor and before the opening of business at such Office or Agency on the
next succeeding Interest Payment Date therefor, such Bearer Security shall be
surrendered without the Coupon relating to such Interest Payment Date and
interest shall not be payable on such Interest Payment Date in respect of the
Registered Security issued in exchange for such Bearer Security, but shall be
payable only to the Holder of such Coupon when due in accordance with the
provisions of this Indenture.

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

         (1)     The Company or the Guarantor may elect to make payment of any
Defaulted Interest to the Person in whose name such Registered Security (or a
Predecessor Security thereof) shall be registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest, which shall be
fixed in the following manner.  The Company or the Guarantor shall notify the
Trustee in writing of the amount of Defaulted Interest proposed to be paid on
such Registered Security and the date of the proposed payment, and at the same
time the Company or the Guarantor, as the case may be, shall deposit with the
Trustee an amount of money equal to the aggregate amount proposed to be paid in
respect of such Defaulted Interest or shall make arrangements satisfactory to
the Trustee for such deposit on or prior to the date of the proposed payment,
such money when so deposited to be held in trust for the benefit of the Person
entitled to such Defaulted Interest as in this Clause provided.  Thereupon, the
Trustee shall fix a Special Record Date for the payment of such Defaulted
Interest which shall be not more than 15 days and not less than 10 days prior
to the date of the proposed payment and not less than 10 days after the receipt
by the Trustee of the notice of the proposed payment. The Trustee shall
promptly notify the Company or the Guarantor, as the case may be, of such
Special Record Date and, in the name and at the expense of the Company or the
Guarantor, as the case may be, shall cause notice of the proposed payment of
such Defaulted Interest and the Special Record Date therefor to be mailed,
first-class postage prepaid, to the Holder of such Registered Security (or a
Predecessor Security thereof) at his address as it appears in the Security
Register not less than 10 days prior to such Special Record Date.  The Trustee
may, in its discretion, in the name and at the expense of the Company or the
Guarantor cause a similar notice to be published at least once in an Authorized
Newspaper of general circulation in the Borough of Manhattan, The City of New
York, but such publication shall not be a condition precedent to the
establishment of such Special Record Date.  Notice of the proposed payment of
such Defaulted Interest and the Special Record Date therefor





                                       38
<PAGE>   48
having been mailed as aforesaid, such Defaulted Interest shall be paid to the
Person in whose name such Registered Security (or a Predecessor Security
thereof) shall be registered at the close of business on such Special Record
Date and shall no longer be payable pursuant to the following clause (2).  In
case a Bearer Security is surrendered at the Office or Agency for such Security
in exchange for a Registered Security after the close of business at such
Office or Agency on any Special Record Date and before the opening of business
at such Office or Agency on the related proposed date for payment of Defaulted
Interest, such Bearer Security shall be surrendered without the Coupon relating
to such Defaulted Interest and Defaulted Interest shall not be payable on such
proposed date of payment in respect of the Registered Security issued in
exchange for such Bearer Security, but shall be payable only to the Holder of
such Coupon when due in accordance with the provisions of this Indenture.

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

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

                 Subject to the foregoing provisions of this Section and
Section 305, each Security delivered under this Indenture upon registration of
transfer of or in exchange for or in lieu of any other Security shall carry the
rights to interest accrued and unpaid, and to accrue, which were carried by
such other Security.


                 Section 308.     Persons Deemed Owners.

                 Prior to due presentment of a Registered Security for
registration of transfer, the Company, the Guarantor, the Trustee and any agent
of the Company, the Guarantor or the Trustee may treat the Person in whose name
such Registered Security is registered in the Security Register as the owner of
such Registered Security for the purpose of receiving payment of principal of,
any premium and (subject to Sections 305 and 307) interest on and any
Additional Amounts with respect to such Registered Security and for all other
purposes whatsoever, whether or not any payment with respect to such Registered
Security shall be overdue, and neither the Company, the Guarantor nor the
Trustee or any agent of the Company, the Guarantor or the Trustee shall be
affected by notice to the contrary.





                                       39
<PAGE>   49
                 The Company, the Guarantor, the Trustee and any agent of the
Company, the Guarantor, or the Trustee may treat the bearer of any Bearer
Security or the bearer of any Coupon as the absolute owner of such Security or
Coupon for the purpose of receiving payment thereof or on account thereof and
for all other purposes whatsoever, whether or not any payment with respect to
such Security or Coupon shall be overdue, and neither the Company, the
Guarantor nor the Trustee or any agent of the Company, the Guarantor or the
Trustee shall be affected by notice to the contrary.

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


                 Section 309.     Cancellation.

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


                 Section 310.     Computation of Interest.

                 Except as otherwise provided in or pursuant to this Indenture
or in any Security, interest on the Securities shall be computed on the basis
of a 360-day year of twelve 30-day months.

                    SATISFACTION AND DISCHARGE OF INDENTURE

                 Section 401.     Satisfaction and Discharge.

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

                 (1)      either

                          (a)     all Securities of such series theretofore
         authenticated and delivered and all Coupons appertaining thereto
         (other than (i) Coupons appertaining to Bearer Securities of such

         series and maturing after such exchange whose surrender is not
         required or has been waived as provided in Section 305, (ii)

         for redemption and maturing after the relevant Redemption Date whose
         surrender has been waived as provided in Section 1107, and (iv)
         Securities and Coupons of such series for whose payment money in the
         applicable Currency has theretofore been deposited in trust or

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

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

                          (i)     have become due and payable, or

                          (ii)    will become due and payable at their Stated

                 expense, of the Company,





                                       41
<PAGE>   51
         and the Company or the Guarantor, in the case of (i), (ii) or (iii)
         above, has deposited or caused to be deposited with the Trustee as
         trust funds in trust for such purpose, money in the Currency in which
         such Securities are payable in an amount sufficient to pay and
         discharge the entire indebtedness on such Securities and any Coupons
         appertaining thereto not theretofore delivered to the Trustee for
         cancellation, including the principal of, any premium and interest on,
         and any Additional Amounts with respect to such Securities and any
         Coupons appertaining thereto, to the date of such deposit (in the case
         of Securities which have become due and payable) or to the Maturity
         thereof, as the case may be;

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

                 (3)      the Company or the Guarantor as the case may be, has
         delivered to the Trustee an Officers' Certificate and an Opinion of
         Counsel, each stating that all conditions precedent herein provided
         for relating to the satisfaction and discharge of this Indenture as to
         such series have been complied with.

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

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


                 Section 402.     Defeasance and Covenant Defeasance.

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





                                       42
<PAGE>   52
time, with respect to such Securities and any Coupons appertaining thereto,
elect to have Section 402(2) or Section 402(3) be applied to such Outstanding
Securities and any Coupons appertaining thereto upon compliance with the
conditions set forth below in this Section 402.

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

                 (3)      Upon the Company's exercise of the above option
applicable to this Section 402(3) with respect to any Securities of or within a
series, the Company and the Guarantor, as the case may be, shall be released
from its obligations under Sections 1005 and 1006, and, to the extent specified
pursuant to Section 301, any other covenant applicable to such Securities,
with respect to such Outstanding Securities and any Coupons appertaining
thereto on and after the date the conditions set forth in clause (4) of this
Section 402 are satisfied (hereinafter, "covenant defeasance"), and such
Securities and any Coupons appertaining thereto shall thereafter be deemed to
be not "Outstanding" for the purposes of any direction, waiver, consent or
declaration or Act





                                       43
<PAGE>   53
of Holders (and the consequences of any thereof) in connection with any such
covenant, but shall continue to be deemed "Outstanding" for all other purposes
hereunder.  For this purpose, such covenant defeasance means that, with respect
to such Outstanding Securities and any Coupons appertaining thereto, the
Company and the Guarantor  may omit to comply with, and shall have no liability
in respect of, any term, condition or limitation set forth in any such Section
or such other covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such Section or such other covenant or by
reason of reference in any such Section or such other covenant to any other
provision herein or in any other document and such omission to comply shall not
constitute a default or an Event of Default under Section 501(3) or 501(4) or
otherwise, as the case may be, but, except as specified above, the remainder of
this Indenture and such Securities and Coupons appertaining thereto and the
Guarantor endorsed thereon shall be unaffected thereby.

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

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

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

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

                          (3) a combination thereof,

                 in any case, in an amount, sufficient, without consideration
                 of any reinvestment of such principal and interest, in the
                 opinion of a nationally recognized firm of independent public
                 accountants expressed in a written certification thereof
                 delivered to the Trustee, to pay and discharge, and which
                 shall be applied by the Trustee (or





                                       44
<PAGE>   54
                 other qualifying trustee) to pay and discharge, the principal
                 of (and premium, if any) and interest, if any, on such
                 Outstanding Securities and any Coupons appertaining thereto on
                 the Stated Maturity of such principal or installment of
                 principal or interest on the day on which such payments are
                 due and payable in accordance with the terms of this Indenture
                 and of such Securities and any Coupons appertaining thereto.

                 (b)      Such defeasance or covenant defeasance shall not
         result in a breach or violation of, or constitute a default under,
         this Indenture or any other material agreement or instrument to which
         the Company or the Guarantor is a party or by which it is bound.

                 (c)      No Event of Default or event which with notice or
         lapse of time or both would become an Event of Default with respect to
         such Securities and any Coupons appertaining thereto shall have
         occurred and be continuing on the date of such deposit and, with
         respect to defeasance only, at any time during the period ending on
         the 91st day after the date of such deposit (it being understood that
         this condition shall not be deemed satisfied until the expiration of
         such period).

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

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

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

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

                 5.       Subject to the provisions of the last paragraph of
Section 1003, all money and Government Obligations (or other property as may be
provided pursuant to Section 301) (including the proceeds thereof) deposited
with the Trustee (or other qualifying trustee, collectively for purposes of
this Section 402(5) and Section 403, the "Trustee") pursuant to clause (4) of
Section 402 in respect of any Outstanding Securities of any series and any
Coupons appertaining thereto shall be held in trust and applied by the Trustee,
in accordance with the provisions of such Securities and any Coupons
appertaining thereto and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as its own Paying Agent)
as the Trustee may determine, to the Holders of such Securities and any Coupons
appertaining thereto of all sums due and to become due thereon in respect of
principal (and premium, if any) and interest and Additional Amounts, if any,
but such money need not be segregated from other funds except to the extent
required by law.

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

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

<PAGE>   56
                 Anything in this Section 402 to the contrary notwithstanding,
the Trustee shall deliver or pay to the Company from time to time upon Company
Request, or the Guarantor, as the case may be, upon Guarantor's Request, any
money or Government Obligations (or other property and any proceeds therefrom)
held by it as provided in clause (4) of this Section 402 which, in the opinion
of a nationally recognized firm of independent public accountants expressed in
a written certification thereof delivered to the Trustee, are in excess of the
amount thereof which would then be required to be deposited to effect a
defeasance or covenant defeasance, as applicable, in accordance with this
Section 402.


                 Section 403.     Application of Trust Money.

                 Subject to the provisions of the last paragraph of Section
1003, all money and Government Obligations deposited with the Trustee pursuant
to Section 401 or 402 shall be held in trust and applied by it, in accordance
with the provisions of the Securities, the Coupons and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company or
the Guarantor acting as its own Paying Agent) as the Trustee may determine, to
the Persons entitled thereto, of the principal, premium, interest and
Additional Amounts for whose payment such money has or Government Obligations
have been deposited with or received by the Trustee; but such money and
Government Obligations need not be segregated from other funds except to the
extent required by law.


                 Section 404.     Reinstatement.

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

                 Section 502.     Acceleration of Maturity; Rescission and
                                  Annulment.

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

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

                 At any time after Securities of any series have been
accelerated and before a judgment or decree for payment of the money due has
been obtained by the Trustee as hereinafter in this Article provided, the
Holders of not less than a majority in principal amount of the Outstanding
Securities of such series, by written notice to the Trustee, the Guarantor and
the Company, may rescind and annul such declaration and its consequences if

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

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

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





                                       50
<PAGE>   60
                 (c)      to the extent that payment of such interest or
         Additional Amounts is lawful, interest upon overdue installments of
         any interest and Additional Amounts at the rate or rates borne by or
         provided for in such Securities, and

                 (d)      all sums paid or advanced by the Trustee hereunder
         and the reasonable compensation, expenses, disbursements and advances
         of the Trustee, its agents and counsel and all other amounts due the
         Trustee under Section 606; and

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

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


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

                 The Company covenants and the Guarantor covenants, in each
case, that if

                 (1)      there is a failure to pay any installment of interest
on or any Additional Amounts with respect to any Security or any Coupon
appertaining thereto when such interest or Additional Amounts shall have become
due and payable and such default continues for a period of 30 days, or

                 (2)      there is a failure to pay the principal of or any
premium on any Security at its Maturity,

the Company or the Guarantor shall, upon demand of the Trustee, pay to the
Trustee, for the benefit of the Holders of such Securities and any Coupons
appertaining thereto, the whole amount of money then due and payable with
respect to such Securities and any Coupons appertaining thereto, with interest
upon the overdue principal, any premium and, to the extent that payment of such
interest shall be legally enforceable, upon any overdue installments of
interest and Additional Amounts at the rate or rates borne by or provided for
in such Securities, and, in addition thereto, such further amount of money as
shall be sufficient to cover the costs and expenses of collection, including
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel and all other amounts due to the Trustee under
Section 606.

                 If the Company or the Guarantor fails to pay the money it is
required to pay the Trustee pursuant to the preceding paragraph forthwith upon
the demand of the Trustee, the Trustee, in its own name and as trustee of an
express trust, may institute a judicial proceeding for the collection of the
money so due and unpaid, and may prosecute such proceeding to judgment or final
decree, and may enforce the same against the Company or the Guarantor or any
other

obligor upon such Securities and any Coupons appertaining thereto and collect
the monies adjudged or decreed to be payable in the manner provided by law out
of the property of the Company, the Guarantor or any other obligor upon such
Securities and any Coupons appertaining thereto, wherever situated.

                 If an Event of Default with respect to Securities of any
series occurs and is continuing, the Trustee may in its discretion proceed to
protect and enforce its rights and the rights of the Holders of Securities of
such series and any Coupons appertaining thereto by such appropriate judicial
proceedings as the Trustee shall deem most effectual to protect and enforce any
such rights, whether for the specific enforcement of any covenant or agreement
in this Indenture or such Securities or in aid of the exercise of any power
granted herein or therein, or to enforce any other proper remedy.


                 Section 504.     Trustee May File Proofs of Claim.

liquidation, bankruptcy, reorganization, arrangement, adjustment, composition
or other judicial proceeding relative to the Company, the Guarantor or any
other obligor upon the Securities or the property of the Company, the Guarantor
or such other obligor or their creditors, the Trustee (irrespective of whether
the principal of the Securities shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the
Trustee shall have made any demand on the Company or the Guarantor for the
payment of any overdue principal, premium, interest or Additional Amounts)
shall be entitled and empowered, by intervention in such proceeding or
otherwise,

                 (1)      to file and prove a claim for the whole amount, or
         such lesser amount as may be provided for in the Securities of such
         series, of the principal and any premium, interest and Additional
         Amounts owing and unpaid in respect of the Securities and any Coupons
         appertaining thereto and to file such other papers or documents as may
         be necessary or advisable in order to have the claims of the Trustee
         (including any claim for the reasonable compensation, expenses,
         disbursements and advances of the Trustee, its agents or counsel) and
         of the Holders of Securities or any Coupons allowed in such judicial
         proceeding, and

                 (2)      to collect and receive any monies or other property
         payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder of Securities or any Coupons to make such payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders of Securities or any Coupons, to pay to the Trustee any
amount due to it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel and any other amounts due the
Trustee under Section 606.

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

                                  of Securities or Coupons.

                 All rights of action and claims under this Indenture or any of
the Securities or Coupons may be prosecuted and enforced by the Trustee without
the possession of any of the Securities or Coupons or the production thereof in
any proceeding relating thereto, and any such proceeding instituted by the
Trustee shall be brought in its own name as trustee of an express trust, and
any recovery or judgment, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, shall be for the ratable benefit of each and every Holder of a
Security or Coupon in respect of which such judgment has been recovered.


                 Section 506.     Application of Money Collected.

                 Any money collected by the Trustee pursuant to this Article
shall be applied in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of principal,
or any premium, interest or Additional Amounts, upon presentation of the
Securities or Coupons, or both, as the case may be, and the notation thereon of
the payment if only partially paid and upon surrender thereof if fully paid:

any series or any Coupons appertaining thereto, or for the appointment of a
receiver or trustee, or for any other remedy hereunder, unless

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

                 (2)      the Holders of not less than 25% in principal amount
         of the Outstanding Securities of such series shall have made written
         request to the Trustee to institute proceedings in respect of such
         Event of Default in its own name as Trustee hereunder;

                 (3)      such Holder or Holders have offered to the Trustee
         reasonable indemnity against the costs, expenses and liabilities to be
         incurred in compliance with such request;

                 (4)      the Trustee for 60 days after its receipt of such
         notice, request and offer of indemnity has failed to institute any
         such proceeding; and

                 (5)      no direction inconsistent with such written request
         has been given to the Trustee during such 60-day period by the Holders
         of a majority in principal amount of the Outstanding Securities of
         such series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture or any Security to affect, disturb or prejudice the rights of
any other such Holders or Holders of Securities of any other series, or to
obtain or to seek to obtain priority or preference over any other Holders or to
enforce any right under this Indenture, except in the manner herein provided
and for the equal and ratable benefit of all such Holders.

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

                 Notwithstanding any other provision in this Indenture, the
Holder of any Security or Coupon shall have the right, which is absolute and
unconditional, to receive payment of the principal of, any premium and (subject
to Sections 305 and 307) interest on, and any Additional Amounts with respect
to such Security or payment of such Coupon, as the case may be, on the
respective Stated Maturity or Maturities therefor specified in such Security or
Coupon (or, in the case of redemption, on the Redemption Date or, in the case
of repayment at the option of such Holder if provided in or pursuant to this
Indenture, on the date such repayment is due, or in the case of a Change in
Control, or as to any Change in Control Purchase Notice given timely, on the





                                       54

Change in Control Purchase Date) and to institute suit for the enforcement of
any such payment, and such right shall not be impaired without the consent of
such Holder.


                 Section 509.     Restoration of Rights and Remedies.

                 If the Trustee or any Holder of a Security or a Coupon has
instituted any proceeding to enforce any right or remedy under this Indenture
and such proceeding has been discontinued or abandoned for any reason, or has
been determined adversely to the Trustee or to such Holder, then and in every
such case the Company, the Guarantor, the Trustee and each such Holder shall,
subject to any determination in such proceeding, be restored severally and
respectively to their former positions hereunder, and thereafter all rights and
remedies of the Trustee and each such Holder shall continue as though no such
proceeding had been instituted.

                 Section 510.     Rights and Remedies Cumulative.

                 Except as otherwise provided with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities or Coupons in the
last paragraph of Section 306, no right or remedy herein conferred upon or
reserved to the Trustee or to each and every Holder of a Security or a Coupon
is intended to be exclusive of any other right or remedy, and every right and
remedy, to the extent permitted by law, shall be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at
law or in equity or otherwise.  The assertion or employment of any right or
remedy hereunder, or otherwise, shall not, to the extent permitted by law,
prevent the concurrent assertion or employment of any other appropriate right
or remedy.


                 Section 511.     Delay or Omission not Waiver.

                 No delay or omission of the Trustee or of any Holder of any
Security or Coupon to exercise any right or remedy accruing upon any Event of
Default shall impair any such right or remedy or constitute a waiver of any
such Event of Default or an acquiescence therein.  Every right and remedy given
by this Article or by law to the Trustee or to any Holder of a Security or a
Coupon may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by such Holder, as the case may be.


                 Section 512.     Control by Holders of Securities.

                 Subject to Section 601(5), the Holders of a majority in
principal amount of the Outstanding Securities of any series shall have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or





                                       55
<PAGE>   65
power conferred on the Trustee with respect to the Securities of such series
and any Coupons appertaining thereto, provided that

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

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

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


                 Section 513.     Waiver of Past Defaults.

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

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

                 (2)      in respect of a covenant or provision hereof which
         under Article Nine cannot be modified or amended without the consent
         of the Holder of each Outstanding Security of such series affected.

                 Upon any such waiver, such default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured, for
every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other default or impair any right consequent thereon.


                 Section 514.     Waiver of Stay or Extension Laws.

                 Each of the Company and the Guarantor covenants that (to the
extent that it may lawfully do so) it will not at any time insist upon, or
plead, or in any manner whatsoever claim or take the benefit or advantage of,
any stay or extension law wherever enacted, now or at any time hereafter in
force, which may affect the covenants or the performance of this Indenture; and
each of  the Company and the Guarantor expressly waives (to the extent that it
may lawfully do so) all benefit or advantage of any such law and covenants that
it will not hinder, delay or impede





                                       56
<PAGE>   66
the execution of any power herein granted to the Trustee, but will suffer and
permit the execution of every such power as though no such law had been
enacted.

                 Section 515.     Undertaking for Costs

                 All parties to this Indenture agree, and each Holder of any
Security by his acceptance thereof shall be deemed to have agreed, that any
court may in its discretion require, in any suit for the enforcement of any
right or remedy under this Indenture, or in any suit against the Trustee for
any action taken or omitted by it as Trustee, the filing by any party litigant
in such suit of any undertaking to pay the costs of such suit, and that such
court may in its discretion assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in such suit having due regard to
the merits and good faith of the claims or defenses made by such party
litigant; but the provisions of this Section 515 shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of
Outstanding Securities of any series, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of (or premium, if any) or
interest, if any, on or Additional Amounts, if any, with respect to any
Security on or after the respective Stated Maturities expressed in such
Security (or, in the case of redemption, on or after the Redemption Date, in
the case of repayment, on or after the date for repayment and, in the case of
Change of Control, on or after the date for payment of the Change of Control
Purchase Price).

                 (c)      whenever in the administration of this Indenture the

         request or direction;

         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture, coupon or other paper or
         document, but the Trustee, in its discretion, may make such further
         inquiry or investigation into such facts or matters as it may see fit,
         and, if the Trustee shall determine to make such further inquiry or
         investigation, it shall be entitled to examine, during business hours
         and upon reasonable notice, the books, records and premises of the
         Company and the Guarantor, personally or by agent or attorney; and

                 (g)      the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through agents or attorneys and the Trustee shall not be responsible
         for any misconduct or negligence on the part of any agent or attorney

         any default (as defined in Section 602) or Event of Default with
         respect to the Securities of any series for which it is acting as
         Trustee unless either (1) a Responsible Officer of the Trustee
         assigned to the Corporate Trust Department of the Trustee (or any
         successor division or department of the Trustee) shall have actual
         knowledge of such default or Event of Default or (2) written notice of

                 (i)      the Trustee shall not be liable for any action taken,
         suffered or omitted by it in good faith and believed by it to be
         authorized or within the discretion or rights or powers conferred upon
         it by this Indenture.


                 Section 602.     Notice of Defaults.

                 Within 90 days after the occurrence of any default hereunder
with respect to the Securities of any series, the Trustee shall transmit by
mail to all Holders of Securities of such series entitled to receive reports
pursuant to Section 703(3), notice of such default hereunder known to the
Trustee, unless such default shall have been cured or waived; provided,
however, that, except in the case of a default in the payment of the principal
of (or premium, if any), or interest, if any, on, or Additional Amounts with
respect to, any Security of such series, the Trustee shall be protected in
withholding such notice if and so long as the board of directors, the executive
committee or a trust committee of directors and/or Responsible Officers of the
Trustee in good faith determine that the withholding of such notice is in the
best interest of the Holders of Securities and Coupons of such series.  For the
purpose of this Section, the term "default" means any event which is, or after
notice or lapse of time or both would become, an Event of Default with respect
to Securities of such series.


                 Section 603.     Not Responsible for Recitals or Issuance of
                                  Securities.

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


                 Section 604.     May Hold Securities.

                 The Trustee, any Authenticating Agent, any Paying Agent, any
Security Registrar or any other Person that may be an agent of the Trustee, the
Company or the Guarantor, in its individual or any other capacity, may become
the owner or pledgee of Securities or Coupons and, subject to Sections 310(b)
and 311 of the Trust Indenture Act, may otherwise deal with the





                                       59
<PAGE>   69
Company and the Guarantor with the same rights it would have if it were not
Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other
Person.


                 Section 605.     Money Held in Trust.

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


                 Section 606.     Compensation and Reimbursement.

                 Each of the Company and the Guarantor agrees:

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

                 (b)      except as otherwise expressly provided herein, to
         reimburse the Trustee upon its request for all reasonable expenses,
         disbursements and advances incurred or made by the Trustee in
         accordance with any provision of this Indenture (including the
         reasonable compensation and the expenses and disbursements of its
         agents and counsel), except any such expense, disbursement or advance
         as may be attributable to the Trustee's negligence or bad faith; and

                 (c)      to indemnify the Trustee and its agents for, and to
         hold them harmless against, any loss, liability or expense incurred
         without negligence or bad faith on their part, arising out of or in
         connection with the acceptance or administration of the trust or
         trusts hereunder, including the costs and expenses of defending
         themselves against any claim or liability in connection with the
         exercise or performance of any of their powers or duties hereunder.

                 As security for the performance of the obligations of the
Company under this Section, the Trustee shall have a lien prior to the
Securities of any series upon all property and funds held or collected by the
Trustee as such, except funds held in trust for the payment of principal of,
and premium or interest on or any Additional Amounts with respect to particular
Securities or any Coupons appertaining thereto.

                 Any compensation or expense incurred by the Trustee after a
default specified by Section 501 is intended to constitute an expense of
administration under any then applicable





                                       60
<PAGE>   70
bankruptcy or insolvency law.  "Trustee" for purposes of this Section 606 shall
include any predecessor Trustee but the negligence or bad faith of any Trustee
shall not affect the rights of any other Trustee under this Section 606.

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

                 Section 607.     Corporate Trustee Required; Eligibility.

                 There shall at all times be a Trustee hereunder that is a
Corporation, organized and doing business under the laws of the United States
of America, any state thereof or the District of Columbia, eligible under
Section 310(a)(1) of the Trust Indenture Act to act as trustee under an
indenture qualified under the Trust Indenture Act and that has a combined
capital and surplus (computed in accordance with Section 310(a)(2) of the Trust
Indenture Act) of at least $50,000,000 subject to supervision or examination by
Federal or state authority.  If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.


                 Section 608.     Resignation and Removal; Appointment of
                                  Successor.

                 (a)      No resignation or removal of the Trustee and no
appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee pursuant
to Section 609.

                 (b)      The Trustee may resign at any time with respect to
the Securities of one or more series by giving written notice thereof to the
Company and the Guarantor.  If the instrument of acceptance by a successor
Trustee required by Section 609 shall not have been delivered to the Trustee
within 30 days after the giving of such notice of resignation, the resigning
Trustee may petition any court of competent jurisdiction for the appointment of
a successor Trustee with respect to the Securities of such series.

                 (c)      The Trustee may be removed at any time with respect
to the Securities of any series by Act of the Holders of a majority in
principal amount of the Outstanding Securities of such series, delivered to the
Trustee and the Company and the Guarantor.

                 (d)      If at any time:

                 (a)      the Trustee shall fail to comply with the obligations
         imposed upon it under Section 310(b) of the Trust Indenture Act with
         respect to Securities of any series after written request therefor by
         the Company, the Guarantor or any Holder of a Security of





                                       61
<PAGE>   71
         such series who has been a bona fide Holder of a Security of such
         series for at least six months, or

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

                 (c)      the Trustee shall become incapable of acting or shall
         be adjudged a bankrupt or insolvent or a receiver of the Trustee or of
         its property shall be appointed or any public officer shall take
         charge or control of the Trustee or of its property or affairs for the
         purpose of rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company, by or pursuant to a Board Resolution,
may remove the Trustee with respect to all Securities or the Securities of such
series, or (ii) subject to Section 315(e) of the Trust Indenture Act, any
Holder of a Security who has been a bona fide Holder of a Security of such
series for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee with respect to all Securities of such series and the
appointment of a successor Trustee or Trustees.

                 (e)      If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for
any cause, with respect to the Securities of one or more series, the Company,
by or pursuant to a Board Resolution, shall promptly appoint a successor
Trustee or Trustees with respect to the Securities of that or those series (it
being understood that any such successor Trustee may be appointed with respect
to the Securities of one or more or all of such series and that at any time
there shall be only one Trustee with respect to the Securities of any
particular series) and shall comply with the applicable requirements of Section
609.  If, within one year after such resignation, removal or incapability, or
the occurrence of such vacancy, a successor Trustee with respect to the
Securities of any series shall be appointed by Act of the Holders of a majority
in principal amount of the Outstanding Securities of such series delivered to
the Company and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment in accordance with the
applicable requirements of Section 609, become the successor Trustee with
respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company.  If no successor Trustee with
respect to the Securities of any series shall have been so appointed by the
Company or the Holders of Securities and accepted appointment in the manner
required by Section 609, any Holder of a Security who has been a bona fide
Holder of a Security of such series for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

Authorized Newspaper in each Place of Payment located outside the United
States.  Each notice shall include the name of the successor Trustee with
respect to the Securities of such series and the address of its Corporate Trust

                 Section 609.     Acceptance of Appointment by Successor.

                 (a)      Upon the appointment hereunder of any successor
Trustee with respect to all Securities, such successor Trustee so appointed
shall execute, acknowledge and deliver to the Company, the Guarantor and the
retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties hereunder of the retiring
Trustee; but, on the request of the Company, the Guarantor or such successor
Trustee, such retiring Trustee, upon payment of its charges, shall execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee and, subject to Section 1003, shall
duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder, subject nevertheless to its
claim, if any, provided for in Section 606.

                 (b)      Upon the appointment hereunder of any successor
Trustee with respect to the Securities of one or more (but not all) series, the
Company, the Guarantor, the retiring Trustee and such successor Trustee shall
execute and deliver an indenture supplemental hereto wherein each successor
Trustee shall accept such appointment and which (1) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and
to vest in, such successor Trustee all the rights, powers, trusts and duties of
the retiring Trustee with respect to the Securities of that or those series to
which the appointment of such successor Trustee relates, (2) if the retiring
Trustee is not retiring with respect to all Securities, shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series as to which the retiring Trustee is not
retiring shall continue to be vested in the retiring Trustee, and (3) shall add
to or change any of the provisions of this Indenture as shall be necessary to
provide for or facilitate the administration of the trusts hereunder by more
than one Trustee, it being understood that nothing herein or in such
supplemental indenture shall constitute such Trustees co-trustees of the same
trust, that each such Trustee shall be trustee of a trust or trusts hereunder
separate and apart from any trust or trusts hereunder administered by any other
such Trustee and that no Trustee shall be responsible for any notice given to,
or received by, or any act or failure to act on the part of any other Trustee
hereunder, and, upon the execution and delivery of such supplemental indenture,
the resignation or removal of the retiring Trustee shall become effective to
the extent provided therein, such retiring Trustee shall have no further
responsibility for the exercise of rights and powers or for the performance of
the duties and obligations vested in the Trustee under this Indenture with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates other than as hereinafter expressly set forth,
and such successor Trustee,





                                       63
<PAGE>   73
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on request of the Company, the Guarantor, or such
successor Trustee, such retiring Trustee, upon payment of its charges with
respect to the Securities of that or those series to which the appointment of
such successor relates and subject to Section 1003 shall duly assign, transfer
and deliver to such successor Trustee, to the extent contemplated by such
supplemental indenture, the property and money held by such retiring Trustee
hereunder with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates, subject to its claim, if any,
provided for in Section 606.

                 (c)      Upon request of any Person appointed hereunder as a
successor Trustee, the Company and the Guarantor shall execute any and all
instruments for more fully and certainly vesting in and confirming to such
successor Trustee all such rights, powers and trusts referred to in paragraph
(1) or (2) of this Section, as the case may be.

                 (d)      No Person shall accept its appointment hereunder as a
successor Trustee unless at the time of such acceptance such successor Person
shall be qualified and eligible under this Article.


                 Section 610.     Merger, Conversion, Consolidation or
                                  Succession to Business.

                 Any Corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any Corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any Corporation succeeding to all or substantially all of the
corporate trust business of the Trustee, shall be the successor of the Trustee
hereunder, without the execution or filing of any paper or any further act on
the part of any of the parties hereto.  In case any Securities shall have been
authenticated but not delivered by the Trustee then in office, any successor by
merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.


                 Section 611.     Appointment of Authenticating Agent.

                 The Trustee may appoint one or more Authenticating Agents
acceptable to the Company with respect to one or more series of Securities
which shall be authorized to act on behalf of the Trustee to authenticate
Securities of that or those series issued upon original issue, exchange,
registration of transfer, partial redemption or partial repayment or pursuant
to Section 306, and Securities so authenticated shall be entitled to the
benefits of this Indenture and shall be valid and obligatory for all purposes
as if authenticated by the Trustee hereunder.  Wherever reference is made in
this Indenture to the authentication and delivery of Securities by the Trustee





                                       64
<PAGE>   74
or the Trustee's certificate of authentication, such reference shall be deemed
to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent.

                 Each Authenticating Agent shall be acceptable to the Company
and the Guarantor and, except as provided in or pursuant to this Indenture,
shall at all times be a corporation that would be permitted by the Trust
Indenture Act to act as trustee under an indenture qualified under the Trust
Indenture Act, is authorized under applicable law and by its charter to act as
an Authenticating Agent and has a combined capital and surplus (computed in
accordance with Section 310(a)(2) of the Trust Indenture Act) of at least
$50,000,000.  If at any time an Authenticating Agent shall cease to be eligible
in accordance with the provisions of this Section, it shall resign immediately
in the manner and with the effect specified in this Section.

                 Any Corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any Corporation
resulting from any merger, conversion or consolidation to which such
Authenticating Agent shall be a party, or any Corporation succeeding to all or
substantially all of the corporate agency or corporate trust business of an
Authenticating Agent, shall be the successor of such Authenticating Agent
hereunder, provided such Corporation shall be otherwise eligible under this
Section, without the execution or filing of any paper or any further act on the
part of the Trustee or the Authenticating Agent.

                 An Authenticating Agent may resign at any time by giving
written notice thereof to the Trustee, the Company and the Guarantor.  The
Trustee may at any time terminate the agency of an Authenticating Agent by
giving written notice thereof to such Authenticating Agent, the Company and the
Guarantor.  Upon receiving such a notice of resignation or upon such a
termination, or in case at any time such Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, the Trustee may
appoint a successor Authenticating Agent which shall be acceptable to the
Company and shall (i) mail written notice of such appointment by first-class
mail, postage prepaid, to all Holders of Registered Securities, if any, of the
series with respect to which such Authenticating Agent shall serve, as their
names and addresses appear in the Security Register, and (ii) if Securities of
the series are issued as Bearer Securities, publish notice of such appointment
at least once in an Authorized Newspaper in the place where such successor
Authenticating Agent has its principal office if such office is located outside
the United States.  Any successor Authenticating Agent, upon acceptance of its
appointment hereunder, shall become vested with all the rights, powers and
duties of its predecessor hereunder, with like effect as if originally named as
an Authenticating Agent.  No successor Authenticating Agent shall be appointed
unless eligible under the provisions of this Section.

                 The Company agrees to pay each Authenticating Agent from time
to time reasonable compensation for its services under this Section.  If the
Trustee makes such payments, it shall be entitled to be reimbursed for such
payments, subject to the provisions of Section 606.

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

                 If an Authenticating Agent is appointed with respect to one or
more series of Securities pursuant to this Section, the Securities of such
series may have endorsed thereon, in addition to or in lieu of the Trustee's
certificate of authentication, an alternate certificate of authentication in
substantially the following form:

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

                                     Authorized Officer

                 If all of the Securities of any series may not be originally
issued at one time, and if the Trustee does not have an office capable of
authenticating Securities upon original issuance located in a Place of Payment
where the Company wishes to have Securities of such series authenticated upon
original issuance, the Trustee, if so requested in writing (which writing need
not be accompanied by or contained in an Officers' Certificate by the Company),
shall appoint in accordance with this Section an Authenticating Agent having an
office in a Place of Payment designated by the Company with respect to such
series of Securities.

account of:

                                  (A) any tax, duty, levy, assessment or other

         Additional Amounts if it had presented such Security for payment on
         any day within such period of thirty (30) days;

         governmental charge;

                                  (C) any tax, assessment or other governmental
         charge which is payable otherwise than by withholding or deduction

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

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

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

                 (4) such Subsidiary Issuer has delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel, each stating that such
consolidation, merger, conveyance, transfer or lease and, if a supplemental
indenture is required in connection with such transaction, such supplemental
indenture comply with this Article and that all conditions precedent herein
provided for relating to such transaction have been complied with.

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

                 Section 803.     Successor Person Substituted for Company.

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

                 Section 804.     Assumption by the Guarantor of the Company's
                                  Obligations

         (a) The Guarantor may, at its option, assume the obligations of the
Company as obligor under any series of Securities and this Indenture; provided
that:

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

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

                  (iii) the Guarantor shall expressly agree in an assumption
agreement or supplemental indenture hereto, executed and delivered to the
Trustee, in form satisfactory to the Trustee, to immediately indemnify
(pursuant to the indemnification procedure described in Section 8.05) the
Holder of each Security against (i) any tax, assessment or governmental charge
imposed on  such Holder or required to be withheld or deducted from any payment
to such Holder (including any governmental charge or withholding tax
attributable to the Guarantor indemnifying such Holder) as a consequence of
such assumption and (ii) any costs or expenses of such assumption (except that
if the Guarantor delivers to the Trustee an opinion of an independent counselor
a tax consultant of recognized standing that the Holders will not recognize
income, gain or loss for U.S. federal income tax purposes as a result of such
assumption by the date of such assumption, a Holder will have indemnification
rights pursuant to the indemnification procedure described in Section 805 only
if and when gain for U.S. federal income tax purposes is actually imposed on
such Holder); and

<PAGE>   82
                 (iv) the Guarantor shall have delivered to the Trustee an
Officers' Certificate stating that such assumption and such assumption
agreement comply with this Article and that all conditions precedent herein
provided for relating to such assumption have been complied with.

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

                 Section 805.     Indemnification Procedure

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

                 (1)  Unless the Guarantor or any such Person, as the case may
be, delivers to the Trustee by the date of an Indemnifiable Transaction an
opinion of an independent counsel or a tax consultant of recognized standing to
the effect that such Indemnifiable Transaction will not be a  taxable event for
U.S. federal income tax purposes, the Guarantor or any such Person, as the case
may be, shall send to each Holder on or prior to the date of such Indemnifiable
Transaction (i) notification explaining the U.S. federal income tax
consequences to each such Holder of such Indemnifiable Transaction and (ii) an
indemnification claim form requesting (A)information concerning each such
Holder's tax basis and holding period in a Security and (B) a statement that
the Holder is not then an entity described in Section 5.01 of the Code that is
exempt from U.S. federal income tax and (iii) a statement setting forth the
address to which each such Holder must remit such form.

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

                 (3) When the Guarantor or any Person, as the case may be,
receives from a Holder an indemnification claim form, the Guarantor or such
Person, as the case may be, shall within 15 business days remit to such Holder
a certified check in an amount equal to the sum of (i) the product of any gain
recognized as a result of the Indemnifiable Transaction and the highest
marginal tax rate in effect at the time of such Indemnifiable Transaction (the
"Indemnification





                                       73
<PAGE>   83
Amount"), and (ii) the product of the Indemnification Amount and such tax rate.
For these purposes, a Holder's gain shall equal the amount by which the fair
market value of a Security at the time of such Indemnifiable Transaction
exceeds such Holder's adjusted tax basis in such Security.

<PAGE>   84
administration of the trusts hereunder by more than one Trustee, pursuant to
the requirements of Section 609; or

                 (f)      to cure any ambiguity or to correct or supplement any
provision herein which may be defective or inconsistent with any other
provision herein, or to make any other provisions with respect to matters or
questions arising under this Indenture which shall not adversely affect the
interests of the Holders of Securities of any series then Outstanding or any

any such action shall not adversely affect the interests of any Holder of a
Security of such series and any Coupons appertaining thereto or any other
Security or Coupon in any material respect; or

                 (j)      to secure the Securities and Guarantees  pursuant to

exchange rights of Holders of Securities of any series; or

                 (l)      to amend or supplement any provision contained herein
or in any supplemental indenture, provided that no such amendment or supplement
shall materially adversely affect the interests of the Holders of any
Securities then Outstanding.


                 Section 902.     Supplemental Indentures with Consent of
                                  Holders.

                 With the consent of the Holders of not less than 66-2/3 in

purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Indenture or of modifying in any manner the

<PAGE>   85
supplemental indenture, without the consent of the Holder of each Outstanding

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


                 Section 903.     Execution of Supplemental Indentures.

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

authenticated and delivered by the Trustee in exchange for Outstanding
Securities of such series.

                 Section 906.     Conformity with Trust Indenture Act.

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

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


                 Section 1002.    Maintenance of Office or Agency.

                 The Company and the Guarantor shall maintain in each Place of
Payment for any series of Securities an Office or Agency where Securities of
such series, and Guarantees with respect thereto (but not Bearer Securities,
except as otherwise provided below, unless such Place of Payment is located
outside the United States), may be presented or surrendered for payment, where
Securities of such series may be surrendered for registration of transfer or
exchange, and where notices and demands to or upon the Company and the
Guarantor in respect of the Securities of such series relating thereto and this
Indenture may be served.  If Securities of a series are issuable as Bearer
Securities, the Company shall maintain, subject to any laws or regulations
applicable thereto, an Office or Agency in a Place of Payment for such series
which is located outside the United States where Securities of such series and
any Coupons appertaining thereto, and  Guarantees with respect thereto, may be
presented and surrendered for payment; provided, however, that if the
Securities of such series are listed on The Stock Exchange of the United
Kingdom and the Republic of Ireland or the Luxembourg Stock Exchange or any
other stock exchange located outside the United States and such stock exchange
shall so require, the Company shall maintain a Paying Agent in London,
Luxembourg or any other required city located outside the United States, as the
case may be, so long as the Securities of such series are listed on such
exchange.  The Company and the Guarantor will give prompt written notice to the
Trustee of the location, and any change in the location, of such Office or
Agency.  If at any time the Company shall fail to maintain any such required
Office or Agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at
the Corporate Trust Office of the Trustee, except that Bearer Securities of
such series and any Coupons appertaining thereto, and Guarantees with respect
thereto, may be presented and surrendered for payment at the place specified
for the purpose with respect to such Securities as





                                       78
<PAGE>   88
provided in or pursuant to this Indenture, and the Company and the Guarantor
hereby appoint the Trustee as their agent to receive all such presentations,
surrenders, notices and demands.

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

                 The Company and the Guarantor  may also from time to time
designate one or more other Offices or Agencies where the Securities of one or
more series, and the Guarantees endorsed thereon, may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall
in any manner relieve the Company or the Guarantor of its obligation to
maintain an Office or Agency in each Place of Payment for Securities of any
series for such purposes.  The Company and the Guarantor shall give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other Office or Agency.  Unless otherwise
provided in or pursuant to this Indenture, the Company and the Guarantor hereby
designate as the Place of Payment for each series of Securities and the
Guarantees endorsed thereon, the Borough of Manhattan, The City of New York,
and initially appoints the Corporate Trust Office of the Trustee as the
Company's or the Guarantor's  Office or Agency in the Borough of Manhattan, The
City of New York for such purpose.  The Company and the Guarantor  may
subsequently appoint a different Office or Agency in the Borough of Manhattan,
The City of New York for the Securities of any series, and the Guarantees
endorsed thereon.

                 Unless otherwise specified with respect to any Securities
pursuant to Section 301, if and so long as the Securities of any series (i) are
denominated in a Foreign Currency or (ii) may be payable in a Foreign Currency,
or so long as it is required under any other provision of this Indenture, then
the Company will maintain with respect to each such series of Securities, or as
so required, at least one exchange rate agent.

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

                 If the Company or the Guarantor, as the case may be, shall at
any time act as its own Paying Agent with respect to any series of Securities,
it shall, on or before each due date of the principal of, any premium or
interest on or Additional Amounts with respect to any of the





                                       79
<PAGE>   89
Securities of such series, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum in the Currency or Currencies in which the
Securities of such series are payable (except as otherwise specified pursuant
to Section 301 for the Securities of such series) sufficient to pay the
principal or any premium, interest or Additional Amounts so becoming due until
such sums shall be paid to such Persons or otherwise disposed of as herein
provided, and shall promptly notify the Trustee of its action or failure so to
act.

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

                 The Company shall cause each Paying Agent for any series of
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent shall:

                 (a)      hold all sums held by it for the payment of the
principal of, any premium or interest on or any Additional Amounts with respect
to Securities of such series in trust for the benefit of the Persons entitled
thereto until such sums shall be paid to such Persons or otherwise disposed of
as provided in or pursuant to this Indenture;

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

                 (c)      at any time during the continuance of any such
default, upon the written request of the Trustee, forthwith pay to the Trustee
all sums so held in trust by such Paying Agent.

                 The Company or the Guarantor, as the case may be, may at any
time, for the purpose of obtaining the satisfaction and discharge of this
Indenture or for any other purpose, pay, or by Company Order of the Company or
the Guarantor direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company, the Guarantor or such Paying Agent, such sums to be held
by the Trustee upon the same terms as those upon which such sums were held by
the Company, the Guarantor or such Paying Agent; and, upon such payment by any
Paying Agent to the Trustee, such Paying Agent shall be released from all
further liability with respect to such sums.

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


                 Section 1004.    Additional Amounts.

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

                 Except as otherwise provided in or pursuant to this Indenture
or the Securities of the applicable series, if the Securities of a series
provide for the payment of Additional Amounts, at least 10 days prior to the
first Interest Payment Date with respect to such series of Securities (or if
the Securities of such series shall not bear interest prior to Maturity, the
first day on which a payment of principal is made), and at least 10 days prior
to each date of payment of principal or interest if there has been any change
with respect to the matters set forth in the below





                                       81
<PAGE>   91
mentioned Officers' Certificate, the Company or the Guarantor, as the case may
be, shall furnish to the Trustee and the principal Paying Agent or Paying
Agents, if other than the Trustee, an Officers' Certificate instructing the
Trustee and such Paying Agent or Paying Agents whether such payment of
principal of and premium, if any, or interest on the Securities of such series
shall be made to Holders of Securities of such series or the Coupons
appertaining thereto who are United States Aliens without withholding for or on
account of any tax, assessment or other governmental charge described in the
Securities of such series.  If any such withholding shall be required, then
such Officers' Certificate shall specify by country the amount, if any,
required to be withheld on such payments to such Holders of Securities or
Coupons, and the Company agrees to pay to the Trustee or such Paying Agent the
Additional Amounts required by the terms of such Securities.  The Company
covenants and the Guarantor covenants to indemnify the Trustee and any Paying
Agent for, and to hold them harmless against, any loss, liability or expense
reasonably incurred without negligence or bad faith on their part arising out
of or in connection with actions taken or omitted by any of them in reliance on
any Officers' Certificate furnished pursuant to this Section.


                 Section 1005.    Limitation on Liens.

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

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

                 (b)  Liens on property to secure (i) all or any portion of the
         cost of exploration, production, gathering, processing, marketing,
         drilling or development of such property, (ii) all or any portion of
         the cost of acquiring, constructing, altering, improving or repairing
         any property or assets, real or personal, or improvements used in
         connection with such property, and (iii) indebtedness incurred by the
         Company or any Subsidiary to provide funds for the activities set
         forth in clauses (i) and (ii) above;

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





                                       82
<PAGE>   92
                 (d)  Liens on the property of any person existing at the time
         such person becomes a Subsidiary;

                 (e)  Liens on any property securing (i) indebtedness incurred
         in connection with the construction, installation or financing of
         pollution control or abatement facilities or other forms of industrial
         revenue bond financing, (ii) indebtedness issued or guaranteed by the
         United States, any state or any department, agency or instrumentality
         of either or (iii) indebtedness issued or guaranteed by (Y) a foreign
         government, any state or any department, agency or instrumentality of
         either or (Z) an international finance agency or any division or
         department thereof, including the World Bank, the International
         Finance Corp. and the Multilateral Investment Guarantee Agency;

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

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

                 (h)      Liens which secure Limited Recourse Indebtedness.

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

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

                 (1)(i) the sale, granting of Liens with respect to or other
         transfer of crude oil, natural gas or other petroleum hydrocarbons in
         place, for a period of time until, or in an amount such that, the
         transferee will realize therefrom a specified amount (however
         determined) of money or such crude oil, natural gas or other petroleum
         hydrocarbons, or (ii) the sale or other transfer of any other interest
         in property of the character commonly referred to as a production
         payment, overriding royalty, forward sales or similar interest; and





                                       83
<PAGE>   93
                 (2) the granting of Liens required by any contract or statute
         in order to permit the Company, the Guarantor or a Subsidiary to
         perform any contract or subcontract made by it with or at the request
         of the United States government or any foreign government or
         international finance agency, any state or any department thereof, or
         any agency or instrumentality thereof, or to secure partial, progress,
         advance or other payments to the Company, the Guarantor or any
         Subsidiary by any such entity pursuant to the provisions of any
         contract or statute.

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

                 "Ordinary Course Lien" shall mean:

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

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

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

                 (d)      Utility easements, building restrictions and such
         other encumbrances or charges against real property as are of a nature
         generally existing with respect to properties of a similar character
         and which do not in any material way affect the marketability of the
         same or interfere with the use thereof in the business of the Company,
         the Guarantor or its Subsidiaries, as the case may be;





                                       84
<PAGE>   94
                 (e)      Liens arising under operating agreements or similar
         agreements in respect of obligations which are not yet due or which
         are being contested in good faith by appropriate proceedings;

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

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

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

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

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


                 Section 1006.    Limitation on Sale/Leaseback Transactions.

                 Neither the Company, the Guarantor nor any Subsidiary will
enter into any Sale/Leaseback Transaction with any Person (other than the
Company or a Subsidiary) providing for a term of more than three years unless:

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

                 (b) since the date of this Indenture and within a period
         commencing six months prior to the Sale/Leaseback Transaction and
         ending six months after the consummation thereof, the Company, the
         Guarantor or such Subsidiary expends for any property (including
         amounts expended for the acquisition, exploration, drilling or
         development thereof, or for additions, alterations, improvements or
         repairs thereto) an amount up to the





                                       85
<PAGE>   95
         net proceeds of such Sale/Leaseback Transaction, and the Company or
         the Guarantor, as the case may be, elects to designate such amount as
         a credit against such Sale/Leaseback Transaction (with any amount of
         such net proceeds not being so designated to be applied as set forth
         in paragraph (c) below); or

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

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

                 Section 1007.    Corporate Existence.

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

                 Section 1008.    Waiver of Certain Covenants.

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


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

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

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

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

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

                            REDEMPTION OF SECURITIES


                 Section 1101.    Applicability of Article.

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


                 Section 1102.    Election to Redeem; Notice to Trustee.

                 The election of the Company to redeem any Securities shall be
evidenced by or pursuant to a Board Resolution or an Officer's Certificate.  In
case of any redemption at the election of the Company of (a) less than all of
the Securities of any series or (b) all of the Securities of any series, with
the same issue date, interest rate or formula, Stated Maturity and other terms,
the Company shall, at least 60 days prior to the Redemption Date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee of such Redemption Date and of the principal amount of Securities
of such series to be redeemed.


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

                 If less than all of the Securities of any series with the same
issue date, interest rate or formula, Stated Maturity and other terms are to be
redeemed, the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee from the Outstanding
Securities of such series not previously called for redemption, by such method
as the Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions of the principal amount of Registered
Securities of such series; provided, however, that no such partial redemption
shall reduce the portion of the principal amount of a Registered Security of
such series not redeemed to less than the minimum denomination for a Security
of such series established herein or pursuant hereto.

                 The Trustee shall promptly notify the Company and the Security
Registrar (if other than itself) in writing of the Securities selected for
redemption and, in the case of any Securities selected for partial redemption,
the principal amount thereof to be redeemed.

                 For all purposes of this Indenture, unless the context
otherwise requires, all provisions relating to the redemption of Securities
shall relate, in the case of any Securities redeemed or to be redeemed only in
part, to the portion of the principal of such Securities which has been or is
to be redeemed.

                 Section 1104.    Notice of Redemption.

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

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

                 All notices of redemption shall state:

                 (a)      the Redemption Date,

                 (b)      the Redemption Price,

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

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

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

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

                 (g)      that, unless otherwise specified in such notice,
Bearer Securities of any series, if any, surrendered for redemption must be
accompanied by all Coupons maturing subsequent to the date fixed for redemption
or the amount of any such missing Coupon or Coupons





                                       89
<PAGE>   99
will be deducted from the Redemption Price, unless security or indemnity
satisfactory to the Company, the Trustee and any Paying Agent is furnished,

                 (h)      if Bearer Securities of any series are to be redeemed
and any Registered Securities of such series are not to be redeemed, and if
such Bearer Securities may be exchanged for Registered Securities not subject
to redemption on the Redemption Date pursuant to Section 305 or otherwise, the
last date, as determined by the Company, on which such exchanges may be made,

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

                 A notice of redemption mailed as contemplated by Section 106
need not identify particular Registered Securities to be redeemed.

                 Notice of redemption of Securities to be redeemed at the
election of the Company shall be given by the Company or, at the Company's
request, by the Trustee in the name and at the expense of the Company.


                 Section 1105.    Deposit of Redemption Price.

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


                 Section 1106.    Securities Payable on Redemption Date.

                 Notice of redemption having been given as aforesaid, the
Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified, and from and after such date
(unless the Company shall default in the payment of the Redemption Price and
accrued interest) such Securities shall cease to bear interest and the Coupons
for such interest appertaining to any Bearer Securities so to be redeemed,
except to the extent provided below, shall be void.  Upon surrender of any such
Security for redemption in accordance with said notice, together with all
Coupons, if any, appertaining thereto maturing after the Redemption Date, such
Security shall be paid by the Company at the Redemption Price, together with
any accrued interest and Additional Amounts to the Redemption Date; provided,
however,





                                       90
<PAGE>   100
that, except as otherwise provided in or pursuant to this Indenture or the
Bearer Securities of such series, installments of interest on Bearer Securities
whose Stated Maturity is on or prior to the Redemption Date shall be payable
only upon presentation and surrender of Coupons for such interest (at an Office
or Agency located outside the United States except as otherwise provided in
Section 1002), and provided, further, that, except as otherwise specified in or
pursuant to this Indenture or the Registered Securities of such series,
installments of interest on Registered Securities whose Stated Maturity is on
or prior to the Redemption Date shall be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the Regular Record Dates therefor according to their terms
and the provisions of Section 307.

                 If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant Coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing Coupons, or the surrender of such
missing Coupon or Coupons may be waived by the Company and the Trustee if there
be furnished to them such security or indemnity as they may require to save
each of them and any Paying Agent harmless.  If thereafter the Holder of such
Security shall surrender to the Trustee or any Paying Agent any such missing
Coupon in respect of which a deduction shall have been made from the Redemption
Price, such Holder shall be entitled to receive the amount so deducted;
provided, however, that any interest or Additional Amounts represented by
Coupons shall be payable only upon presentation and surrender of those Coupons
at an Office or Agency for such Security located outside of the United States
except as otherwise provided in Section 1002.

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


                 Section 1107.    Securities Redeemed in Part.

                 Any Registered Security which is to be redeemed only in part
shall be surrendered at any Office or Agency for such Security (with, if the
Company or the Trustee so requires, due endorsement by, or a written instrument
of transfer in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or his attorney duly authorized in writing) and the
Company shall execute, the Guarantees of the Guarantor shall be endorsed on and
the Trustee shall authenticate and deliver to the Holder of such Security
without service charge, a new Registered Security or Securities of the same
series, containing identical terms and provisions, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Security so
surrendered.  If a Security in global form is so surrendered, the Company shall
execute, and the Trustee shall authenticate and deliver to the U.S. Depository
or other Depository for such Security in global form as shall be specified in
the Company Order with respect thereto to the Trustee, without





                                       91
<PAGE>   101
service charge, a new Security in global form in a denomination equal to and in
exchange for the unredeemed portion of the principal of the Security in global
form so surrendered.

                       REPAYMENT AT THE OPTION OF HOLDERS


                 Section 1201. Applicability of Article.

                 Securities of any series which are repayable at the option of
the Holders thereof before their Stated Maturity shall be repaid in accordance
with the terms of the Securities of such series. The repayment of any principal
amount of Securities pursuant to such option of the Holder to require repayment
of Securities before their Stated Maturity, for purposes of Section 309, shall
not operate as a payment, redemption or satisfaction of the Indebtedness
represented by such Securities unless and until the Company, at its option,
shall deliver or surrender the same to the Trustee with a directive that such
Securities be canceled. Notwithstanding anything to the contrary contained in
this Section 1201, in connection with any repayment of Securities, the Company
may arrange for the purchase of any Securities by an agreement with one or more
investment bankers or other purchasers to purchase such Securities by paying to
the Holders of such Securities on or before the close of business on the
repayment date an amount not less than the repayment price payable by the
Company on repayment of such Securities, and the obligation of the Company to
pay the repayment price of such Securities shall be satisfied and discharged to
the extent such payment is so paid by such purchasers.

                        SECURITIES IN FOREIGN CURRENCIES


                 Section 1301.    Applicability of Article.

                 Whenever this Indenture provides for (i) any action by, or the
determination of any of the rights of, Holders of Securities of any series in
which not all of such Securities are denominated in the same Currency, or (ii)
any distribution to Holders of Securities, in the absence of any provision to
the contrary in the form of Security of any particular series or pursuant to
this Indenture or the Securities, any amount in respect of any Security
denominated in a Currency other than Dollars shall be treated for any such
action or distribution as that amount of Dollars that could be obtained for
such amount on such reasonable basis of exchange and as of the record date with
respect to Registered Securities of such series (if any) for such action,
determination of rights or distribution (or, if there shall be no applicable
record date, such other date reasonably





                                       92
<PAGE>   102
proximate to the date of such action, determination of rights or distribution)
as the Company or the Guarantor  may specify in a written notice to the Trustee
or, in the absence of such written notice, as the Trustee may determine.


                                ARTICLE FOURTEEN

                       MEETINGS OF HOLDERS OF SECURITIES


                 Section 1401.    Purposes for Which Meetings May Be Called.

                 A meeting of Holders of Securities of any series may be called
at any time and from time to time pursuant to this Article to make, give or
take any request, demand, authorization, direction, notice, consent, waiver or
other Act provided by this Indenture to be made, given or taken by Holders of
Securities of such series.


                 Section 1402.    Call, Notice and Place of Meetings.

                 (a)      The Trustee may at any time call a meeting of Holders
of Securities of any series for any purpose specified in Section 1401, to be
held at such time and at such place in the Borough of Manhattan, The City of
New York, or, if Securities of such series have been issued in whole or in part
as Bearer Securities, in London or in such place outside the United States as
the Trustee shall determine.  Notice of every meeting of Holders of Securities
of any series, setting forth the time and the place of such meeting and in
general terms the action proposed to be taken at such meeting, shall be given,
in the manner provided in Section 106, not less than 21 nor more than 180 days

                 (b)      In case at any time the Company or the Guarantor (by

amount of the Outstanding Securities of any series shall have requested the
Trustee to call a meeting of the Holders of Securities of such series for any
purpose specified in Section 1401, by written request setting forth in
reasonable detail the action proposed to be taken at the meeting, and the
Trustee shall not have mailed notice of or made the first publication of the
notice of such meeting within 21 days after receipt of such request (whichever
shall be required pursuant to Section 106) or shall not thereafter proceed to

Borough of Manhattan, The City of New York, or, if Securities of such series
are to be issued as Bearer Securities, in London for such meeting and may call

the Outstanding Securities of a series shall constitute a quorum for a meeting
of Holders of Securities of such series; provided, however, that if any action
is to be taken at such meeting with respect to a consent or waiver which this
Indenture expressly provides may be given by the Holders of at least 66-2/3% in
principal amount of the Outstanding Securities of a series, the Persons
entitled to vote 66-2/3% in principal amount of the Outstanding Securities of
such series shall constitute a quorum.  In the absence of a quorum within 30
minutes after the time appointed for any such meeting, the meeting shall, if
convened at the request of Holders of Securities of such series, be dissolved.
In any other case the meeting may be adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such meeting.  In the absence of a quorum at any such adjourned meeting, such
adjourned meeting may be further adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such adjourned meeting.  Notice of the reconvening of any adjourned meeting
shall be given as provided in Section 1402(1), except that such notice need be
given only once not less than five days prior to the date on which the meeting
is scheduled to be reconvened.  Notice of the reconvening of an adjourned
meeting shall state expressly the percentage, as provided above, of the
principal amount of the Outstanding Securities of such series which shall

                 Except as limited by the proviso to Section 902, any
resolution presented to a meeting or adjourned meeting duly reconvened at which
a quorum is present as aforesaid may be adopted only by the affirmative vote of
the Holders of a majority in principal amount of the Outstanding Securities of
that series; provided, however, that, except as limited by the proviso to
Section 902, any resolution with respect to any consent or waiver which this
Indenture expressly provides may be given by the Holders of at least 66-2/3% in
principal amount of the Outstanding Securities of a series may be adopted at a
meeting or an adjourned meeting duly convened and at which a quorum is present
as aforesaid only by the affirmative vote of the Holders of 66-2/3% in
principal amount of the Outstanding Securities of that series; and provided,
further, that, except as limited by the proviso to Section 902, any resolution
with respect to any request, demand, authorization, direction, notice, consent,
waiver or other Act which this Indenture expressly





                                       94
<PAGE>   104

Securities of a series may be adopted at a meeting or an adjourned meeting duly
reconvened and at which a quorum is present as aforesaid by the affirmative
vote of the Holders of such specified percentage in principal amount of the
Outstanding Securities of such series.

                 Any resolution passed or decision taken at any meeting of
Holders of Securities of any series duly held in accordance with this Section
shall be binding on all the Holders of Securities of such series and the
Coupons appertaining thereto, whether or not such Holders were present or
represented at the meeting.


                 Section 1405.    Determination of Voting Rights; Conduct and
                                  Adjournment of Meetings.

                 (a)      Notwithstanding any other provisions of this
Indenture, the Trustee may make such reasonable regulations as it may deem
advisable for any meeting of Holders of Securities of such series in regard to
proof of the holding of Securities of such series and of the appointment of
proxies and in regard to the appointment and duties of inspectors of votes, the
submission and examination of proxies, certificates and other evidence of the
right to vote, and such other matters concerning the conduct of the meeting as
it shall deem appropriate.  Except as otherwise permitted or required by any
such regulations, the holding of Securities shall be proved in the manner
specified in Section 104 and the appointment of any proxy shall be proved in
the manner specified in Section 104 or by having the signature of the person
executing the proxy witnessed or guaranteed by any trust company, bank or
banker authorized by Section 104 to certify to the holding of Bearer
Securities.  Such regulations may provide that written instruments appointing
proxies, regular on their face, may be presumed valid and genuine without the
proof specified in Section 104 or other proof.

                 (b)      The Trustee shall, by an instrument in writing,
appoint a temporary chairman of the meeting, unless the meeting shall have been
called by the Company, the Guarantor  or by Holders of Securities as provided
in Section 1402(2), in which case the Company or the Holders of Securities of
the series calling the meeting, as the case may be, shall in like manner
appoint a temporary chairman.  A permanent chairman and a permanent secretary
of the meeting shall be elected by vote of the Persons entitled to vote a
majority in principal amount of the Outstanding Securities of such series
represented at the meeting.

                 (c)      At any meeting, each Holder of a Security of such
series or proxy shall be entitled to one vote for each $1,000 principal amount
of Securities of such series held or represented by him; provided, however,
that no vote shall be cast or counted at any meeting in respect of any Security
challenged as not Outstanding and ruled by the chairman of the meeting to be
not Outstanding. The chairman of the meeting shall have no right to vote,
except as a Holder of a Security of such series or proxy.

<PAGE>   105
                 (d)      Any meeting of Holders of Securities of any series
duly called pursuant to Section 1402 at which a quorum is present may be
adjourned from time to time by Persons entitled to vote a majority in principal
amount of the Outstanding Securities of such series represented at the meeting;
and the meeting may be held as so adjourned without further notice.

                                  Meetings.

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

         power of the Voting Stock of the sole surviving or continuing
         corporation outstanding immediately following the consummation thereof
         of such consolidation or merger.

         "Exchange Act of 1934" shall mean the Securities Exchange Act of 1934,
as amended.

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

                 (f) that the Securities must be surrendered to the Trustee or
         the Office or Agency to collect payment;

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

                 (h) the procedures the Holder must follow to exercise rights
         under this Section 1501(1) and a brief description of those rights;
         and

                 (i) the procedures for withdrawing a Change in Control
         Purchase Notice.

         (3)  A Holder may exercise its rights specified in Section 1501(1)

                 (a) the certificate number or numbers of the Security or
Securities which the Holder will deliver to be purchased;





                                       98
<PAGE>   108
                 (b) the portion of the principal amount of the Security or
Securities which the Holder will deliver to be purchased, which portion must be
$1,000 or an integral multiple thereof; and

                 (c) that such Security or Securities shall be purchased on the
Change in Control Purchase Date pursuant to the terms and conditions specified
in the Securities.

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

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


                 Section 1502.  Effect of Change in Control Purchase Notice.

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

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

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





                                       99
<PAGE>   109
                 (b) the principal amount of the Security or Securities with
respect to which such notice of withdrawal is being submitted; and

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

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


                 Section 1503.  Deposit of Change in Control Purchase Price.

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


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

                 In connection with any purchase of securities under Section
1601 hereof, the Guarantor  shall (a) comply with Rule 13e-4 under the Exchange
Act of 1934, if applicable, (b) file the related Schedule 13E-4 (or any
successor schedule, form or report) under the Exchange Act of 1934, if
applicable, and (c) otherwise comply with all Federal and state securities laws
regulating the purchase of the Securities (including positions of the
Commission under applicable no-action letters) so as to permit the rights and
obligation under Section 1501 to be exercised in the time and in the manner
specified in Section 1501 and 1502.

                 Section 1505.   Repayment to the Guarantor.

<PAGE>   110

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

                                ARTICLE SIXTEEN

                                   GUARANTEES


                 Section 1601. Guarantee.

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

                 The Guarantor hereby agrees that any amounts to be paid by it
hereunder shall be paid without deduction or withholding for or on account of
any and all present or future tax, duty, assessment or governmental charge
imposed upon or as a result of such payment by the Government of the United
States, or any state or other political subdivision or taxing authority
thereof or therein, or if deduction or withholding  of any such tax, duty,
assessment or charge shall at any time be required by or on behalf of the
Government of the United States or any such state, political subdivision or
taxing authority, the Guarantor shall pay such additional amount in respect of
principal, premium, if any, and interest, if any, as may be necessary in order
that the net amounts paid to the Holder of a Security or the Trustee on behalf
of the Holder of such





                                      101
<PAGE>   111
Security, as the case may be, pursuant to this guarantee after such deduction
or withholding shall not be less than the amount provided for in such Security
to be then due and payable; except that no such additional amount shall be
payable in respect of any Security to any Holder (a) who is subject to such
tax, duty, assessment or governmental charge in respect of such Security by
reason of his being connected with the United States otherwise than merely by
the holding or ownership of such Security, or (b) who is not dealing at arm's
length with the Guarantor (within the meaning of the Internal Revenue Code as
amended from time to time).

                 The Guarantor hereby agrees that its obligations hereunder
shall be as if principal debtor and not merely surety, and shall be absolute
and unconditional, irrespective of the validity, regularity or enforceability
of such Security or this Indenture, the absence of any action to enforce the
same, any waiver or consent by the Holder of such Security  or by the Trustee
with respect to any provisions thereof or of this Indenture, the obtaining of
any judgment against the Company or any action to enforce the same or any other
circumstances which might otherwise constitute a legal or equitable discharge
or defense of a guarantor. The Guarantor hereby waives the benefits of division
and discussion, diligence, presentment, demand of payment, filing of claims
with a court in the event of insolvency or bankruptcy of the Company, any
right to require a proceeding first against he Company, protest or notice with
respect to such  Security or the indebtedness evidenced thereby and all demands
whatsoever, and covenants that this guarantee will not be discharged in respect
of such Security except by complete performance  of the obligations contained
in such Security and in this guarantee. The Guarantor hereby agrees that, in
the event of a default in payment of principal (or premium, if any) or
interest, if any, on such Security, or a default in any payment referred to
therein, legal  proceedings may be instituted by the Trustee on behalf of, or
by, the Holder of such Security, on the terms and conditions set forth in this
Indenture, directly against the Guarantor to enforce this guarantee without
first proceeding against the Company.

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

                 Section 1602. Execution and Delivery of Guarantees.

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





                                      102
<PAGE>   112
                 The Guarantees shall be executed on behalf of the Guarantor by
its Chairman of the Board, a Vice Chairman of the Board, its President or one
of its Vice Presidents, under its corporate seal reproduced thereon attested by
its Secretary or one of its Assistant Secretaries.  The  signature of any of
these officers on the Guarantees may be manual or facsimile.

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

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

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

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

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

                 Section 1701.    Submission to Jurisdiction

                 The Company hereby acknowledges and agrees for the benefit of
the Trustee and the Holders of Securities and Coupons that any judicial
proceedings instituted in relation to any matter arising out of this Indenture,
the Securities or the Coupons may be brought in any court having subject matter
jurisdiction in the Borough of Manhattan, The City of New York, New York

this Indenture, the Company hereby irrevocably accepts generally and
unconditionally, the jurisdiction of the aforesaid courts, acknowledges their
competence and irrevocably agrees to be bound by any judgment rendered in any
such proceeding.  The Company also irrevocably and unconditionally waives for
the benefit of the Turste and the Holders of Securities and Coupon any immunity
from jurisdiction and any immunity from legal process (whether through service
or notice, attachment prior to judgment, attachment in aid of execution,
execution or otherwise) in respect of this Indenture.  The Company hereby
irrevocably designates and appoints for the benefit of the Trustee and the
Holders of Securities, Guarantees and Coupons for the term of this Indenture CT

to be delivered to CT Corporation, 1633 Broadway, New York, New York 10019)
brought against it with respect to any such proceeding in any such court in the
City of New York, such service being hereby acknowledged by the Company to be
effective and binding service on it in every respect whether or not the Company
shall then be doing or shall have at any time done business in New York.  Such
appointment shall be irrevocable so long as any of the Securities or Coupons or
the obligations of the Company hereunder remain outstanding until the
appointment of a successor by the Company and such successor's acceptance of
such appointment.  Upon such acceptance, the Company shall notify the Trustee
of the name and address of such successor.  The Company further agrees for the
benefit of the Trustee and the Holders of the Securities and the Coupons to
take any and all action, including the execution and filing of any and all such
documents and instruments, as may be necessary to continue such designation and
appointment of said CT Corporation in full force and effect so long as any of
the Securities or Coupons or the obligations of the Company hereunder shall be
outstanding.  The Trustee shall not be obligated and shall have no
responsibility with respect to any failure by the Company to take such action.
Nothing herein shall affect the right to serve process in any other manner
permitted by any law or limit the right of the Trustee or any Holder to
institute proceedings against the Company in the courts of any other
jurisdiction or jurisdictions.

(1) Undistributed income of less-than-50% owned affiliates is excluded.

(2) Apache guaranteed and was contingently liable for certain debt. This debt,
    primarily associated with partnership operations, totaled $1.7 million at
    December 31, 1996. The outstanding balance was repaid in January 1997 and
    the facility was terminated. Fixed charges, relating to debt for which
    Apache was contingently liable, have not been included in the fixed charges
    for any of the periods shown above.

(3) Represents the portion of rental expense assumed to be attributable to
    interest factors of related rental obligations determined at interest rates
    appropriate for the period during which the rental obligations were
    incurred. Approximately 32% to 34% applies for all periods presented.

(4) Earnings were inadequate to cover fixed charges by $14.8 million for 1992
    due to write downs of the carrying value of the U.S. and Canadian oil and
    gas properties of DEK Energy Company ("DEKALB"), formerly known as DEKALB
    Energy Company, and losses incurred on the divestiture of DEKALB's U.S. oil
    and gas properties.
