                                 THE CORPORATION

         The Corporation, incorporated under the laws of New York in 1885, is
among the world's largest producers of copper. In 1996, the Corporation produced
770,400 tons of copper for its own account from its worldwide mining operations
and an additional 162,900 tons of copper for the accounts of minority interest
owners. Gold, silver, molybdenum, copper chemicals and sulfuric acid are also
produced as by-products of the Corporation's copper operations.

         Production of copper for the Corporation's own account from its U.S.
operations constituted more than 25 percent of the copper mined in the United
States in 1996. Much of the Corporation's U.S. copper production, after
electrowinning or smelting and refining, together with additional copper
purchased from others, is used by the Corporation to produce continuous-cast
copper rod, the basic feed for the electrical wire and cable industry. The
Corporation is the world's largest producer of copper rod.



                                       3
<PAGE>   6
        The Corporation's international mining interests include Candelaria, its
major copper mine in Chile, which commenced operations in October 1994, and
other operations and investments in Chile, Peru and South Africa. These
operations produce a variety of metals and minerals including copper, gold,
fluorspar, silver, lead and zinc. The Corporation also explores for metals and
minerals throughout the world.

         The Corporation also manufactures engineered products principally for
the transportation, energy and telecommunications sectors worldwide through a
group of industrial companies. Specialty chemicals are produced through
Columbian Chemicals Company which is among the world's largest producers of
carbon black, a reinforcing agent in natural and synthetic rubber that increases
the service life of tires, hoses, belting and other products, for the rubber
industry. It also produces specialty carbon black for other industrial
applications such as pigments for printing, coatings, plastics and other
non-rubber applications. Accuride Corporation is the largest North American
manufacturer of steel wheels and rims for medium and heavy trucks, trailers and
buses. The Corporation produces wire and cable products and specialty conductors
at U.S. and international operations through Phelps Dodge Magnet Wire Company
and Phelps Dodge International Corporation. Phelps Dodge Magnet Wire Company,
the world's largest manufacturer of magnet wire, produces magnet wire and other
copper products for sale principally to original equipment manufacturers for use
in electrical motors, generators, transformers and other products. Phelps Dodge
International Corporation manufactures telecommunication and energy cables and
specialty conductors.

         The Corporation's principal executive offices are located at 2600 N.
Central Avenue, Phoenix, Arizona 85004-3014, and its telephone number is (602)
234-8100. Unless the context otherwise requires, "Corporation," as used in this
Prospectus, includes Phelps Dodge Corporation and its consolidated subsidiaries.


                                USE OF PROCEEDS

         Unless otherwise set forth in the applicable Prospectus Supplement, the
Corporation will use the net proceeds from the sale of the Debt Securities for
general corporate purposes, which may include acquisitions, purchases of its own
capital stock, reduction of the Corporation's outstanding borrowings and payment
of capital outlays. Pending such use, the proceeds may be invested temporarily
in short term marketable securities. A more detailed description of the use of
proceeds of any specific offering of Offered Securities shall be set forth in
the Prospectus Supplement pertaining to such offering.


                       RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth the Corporation's ratio of earnings to fixed
charges:

*     For the purpose of computing the ratio of earnings to fixed charges,
      earnings consist of income before income taxes, minority interests in
      majority-owned subsidiaries and equity in net earnings of affiliated
      companies, plus the Corporation's share of earnings of 50-percent-owned
      persons, distributed earnings of less-than-50-percent-owned persons and
      fixed charges (excluding capitalized interest, but including amortization
      of amounts previously capitalized). Minority interests in majority-owned
      subsidiaries were not deducted from earnings as all such subsidiaries had
      fixed charges. Fixed charges consist of interest (including capitalized
      interest) on all indebtedness, amortization of debt discount and expense,
      and that portion of rental expense which the Corporation believes to be
      representative of interest. A statement setting forth the computation of
      the unaudited ratios of earnings to fixed charges is filed as Exhibit 12
      to the Registration Statement of which this Prospectus is a part.

**    The ratio of earnings to fixed charges would have been 9.0 in 1994 before
      the effect of a $157.7 million non-recurring provision for environmental
      costs and asset dispositions.


                         DESCRIPTION OF DEBT SECURITIES

            The Debt Securities offered hereby are to be issued in one or more
series under an Indenture, dated as of September 22, 1997 (the "Indenture"),

limited to U.S. $500,000,000 aggregate principal amount (or (i) its equivalent
(based on the applicable exchange rate at the time of issue), if Debt Securities
are issued with principal amounts denominated in one or more foreign or
composite currencies or currency units as shall be designated by the
Corporation, or (ii) such greater amount, if Debt Securities are issued at an
original issue discount, as shall result in aggregate proceeds of U.S.
$500,000,000 to the Corporation). The statements herein relating to the Debt
Securities and the Indenture are summaries and are subject to the detailed
provisions of the Indenture. A copy of the form of Indenture is filed as an
exhibit to the Registration Statement of which this Prospectus is a part. The
following summaries of certain provisions of the Indenture do not purport to be
complete and are subject to, and are qualified in their entirety by reference
to, all the provisions of the Indenture (as amended or supplemented from time to
time), including the definitions therein of certain terms capitalized in this
Prospectus. Whenever particular Sections or defined terms of the Indenture are
referred to herein or in a Prospectus Supplement, such Sections or defined terms
are incorporated herein or therein by reference.

GENERAL

            The Debt Securities will be unsecured obligations of the
Corporation. Unless otherwise specified in a Prospectus Supplement, the Debt
Securities will not be subordinated to any other unsecured indebtedness of the
Corporation. The Indenture does not limit the aggregate amount of Debt
Securities which may be issued thereunder, nor does it limit the incurrence or
issuance of other secured or unsecured debt of the Corporation.

            Most of the assets of the Corporation are owned by its subsidiaries
and, accordingly, the Debt Securities are effectively subordinated to all
existing and future liabilities of the Corporation's subsidiaries. The
Corporation's rights and the rights of its creditors, including holders of Debt
Securities, to participate in any distribution of the assets of any subsidiary
upon the latter's liquidation, recapitalization or insolvency would be subject
to the prior claims of the subsidiary's creditors, except 


                                       5
<PAGE>   8
to the extent that the Corporation might itself be a creditor with recognized
claims against the subsidiary. At June 30, 1997, outstanding debt of the
Corporation's subsidiaries equaled $401.1 million. At June 30, 1997, outstanding
debt of the Corporation (excluding subsidiaries) equaled $446.1 million, all of
which debt would rank equally with the Debt Securities.

            Reference is made to the Prospectus Supplement which accompanies
this Prospectus for a description of the specific series of Debt Securities
being offered thereby, including (1) the title of such Debt Securities; (2) any
limit upon the aggregate principal amount of such Debt Securities; (3) the date
or dates on which the principal of and premium, if any, on such Debt Securities
will mature or the method of determining such date or dates; (4) the rate or
rates (which may be fixed or variable) at which such Debt Securities will bear
interest, if any, or the method of calculating such rate or rates; (5) the date
or dates from which interest, if any, will accrue or the method by which such
date or dates will be determined; (6) the date or dates on which interest, if
any, will be payable and the record date or dates therefor; (7) the place or
places where principal of, premium, if any, and interest, if any, on such Debt
Securities will be payable; (8) the period or periods within which, the price or
prices at which, the currency or currencies (including composite currency,
currency unit or units) in which, and the terms and conditions upon which, such
Debt Securities may be redeemed, in whole or in part, at the option of the
Corporation; (9) the obligation, if any, of the Corporation to redeem or
purchase such Debt Securities pursuant to any sinking fund or analogous
provisions or upon the happening of a specified event or at the option of a
holder thereof and the period or periods within which, the price or prices at
which and the other terms and conditions upon which, such Debt Securities shall
be redeemed or purchased, in whole or in part, pursuant to such obligations;
(10) the denominations in which such Debt Securities are authorized to be
issued; (11) the currency or currency unit for which Debt Securities may be
purchased or in which Debt Securities may be denominated and/or the currency or
currencies (including composite currency, currency unit or units) in which
principal of, premium, if any, and interest, if any, on such Debt Securities
will be payable and whether the Corporation or the holders of any such Debt
Securities may elect to receive payments in respect of such Debt Securities in a
currency or currency unit other than that in which such Debt Securities are
stated to be payable; (12) if the amount of principal of, or any premium or
interest on, any of such Debt Securities may be determined with reference to an
index or pursuant to a formula, the manner in which such amounts will be
determined; (13) if other than the principal amount thereof, the portion of the
principal amount of such Debt Securities which will be payable upon declaration
of the acceleration of the maturity thereof or the method by which such portion
shall be determined; (14) the person to whom any interest on any such Debt
Security shall be payable if other than the person in whose name such Debt
Security is registered on the applicable record date; (15) any addition to, or
modification or deletion of, any Event of Default or any covenant of the
Corporation specified in the Indenture with respect to such Debt Securities;
(16) the application, if any, of such means of defeasance or covenant defeasance
as may be specified for such Debt Securities; (17) whether such Debt Securities
are to be issued in whole or in part in the form of one or more temporary or
permanent global securities and, if so, the identity of the depositary for such
global security or securities; and (18) any other special terms pertaining to
such Debt Securities. See Section 3.1 of the Indenture. Unless otherwise
specified in the applicable Prospectus Supplement, the Debt Securities will not
be listed on any securities exchange.

            Unless otherwise specified in the applicable Prospectus Supplement,
Debt Securities will be issued in fully registered form without coupons in
denominations of $1,000 or any integral multiples of $1,000. Where Debt
Securities of any series are issued in bearer form, the special restrictions and
considerations, including special offering restrictions and special Federal
income tax considerations, applicable to any such Debt Securi-


                                       6
<PAGE>   9
ties and to payment on and transfer and exchange of such Debt Securities will be
described in the applicable Prospectus Supplement. Bearer Debt Securities will
be transferable by delivery. See Section 3.5 of the Indenture.

            Debt Securities may be sold at a substantial discount below their
stated principal amount, bearing no interest or interest at a rate which at the
time of issuance is below market rates. Certain Federal income tax consequences
and special considerations applicable to any such Debt Securities will be
described in the applicable Prospectus Supplement.

            If the purchase price of any of the Debt Securities is payable in
one or more foreign or composite currencies or currency units or if any Debt
Securities are denominated in one or more foreign or composite currencies or
currency units or if the principal of, premium, if any, or interest, if any, on
any Debt Securities is payable in one or more foreign or composite currencies,
or currency units, the restrictions, elections, certain Federal income tax
considerations, specific terms and other information with respect to such issue
of Debt Securities and such foreign or composite currency or currency units will
be set forth in the applicable Prospectus Supplement.

            If any index is used to determine the amount of payments of
principal of, premium, if any, or interest on any series of Debt Securities,
special Federal income tax, accounting and other considerations applicable
thereto will be described in the applicable Prospectus Supplement.

            The general provisions of the Indenture do not afford holders of the
Debt Securities protection in the event of a highly leveraged or other
transaction involving the Corporation that may adversely affect holders of the
Debt Securities.

PAYMENT, REGISTRATION, TRANSFER AND EXCHANGE

            Unless otherwise provided in the applicable Prospectus Supplement,
payments in respect of the Debt Securities will be made in the designated
currency at the office or agency of the Corporation maintained for that purpose
as the Corporation may designate from time to time, except that, at the option
of the Corporation, interest payments, if any, on Debt Securities in registered
form may be made (i) by checks mailed to the holders of Debt Securities entitled
thereto at their registered addresses or (ii) by wire transfer to an account
maintained by the person entitled thereto as specified in the Register. See
Sections 3.7(a) and 9.2 of the Indenture. Unless otherwise indicated in an
applicable Prospectus Supplement, payment of any installment of interest on Debt
Securities in registered form will be made to the person in whose name such Debt
Security is registered at the close of business on the regular record date for
such interest. See Section 3.7(a) of the Indenture.

            Payment in respect of Debt Securities in bearer form will be made in
the currency and in the manner designated in the Prospectus Supplement, subject
to any applicable laws and regulations, at such paying agencies outside the
United States as the Corporation may appoint from time to time. The paying
agents outside the United States initially appointed by the Corporation for a
series of Debt Securities will be named in the Prospectus Supplement. The
Corporation may at any time designate additional paying agents or rescind the
designation of any paying agents, except that, if Debt Securities of a series
are issuable as Registered Securities, the Corporation will be required to
maintain at least one paying agent in each Place of Payment for such series and,
if Debt Securities of a series are issuable as Bearer Securities, the
Corporation will be required to maintain a paying agent in a Place of Payment
outside the United States where Debt Securities of such series and any coupons
appertaining thereto may be presented and surrendered for payment. See Section
9.2 of the Indenture.


                                       7
<PAGE>   10
            All moneys paid by the Corporation to the Trustee or a paying agent
for the payment of the principal of, or any premium or interest on, any Debt
Security which remain unclaimed at the end of two years after such principal,
premium or interest has become due and payable will be repaid to the
Corporation, and the holder of such Security thereafter may look only to the
Corporation for payment thereof. See Section 9.3 of the Indenture.

            Unless otherwise provided in the applicable Prospectus Supplement,
Debt Securities in registered form will be transferable or exchangeable at the
agency of the Corporation maintained for such purpose as designated by the
Corporation from time to time. See Sections 3.5 and 9.2 of the Indenture. Debt
Securities may be transferred or exchanged without service charge, other than
any tax or other governmental charge imposed in connection therewith. See
Section 3.5 of the Indenture.

GLOBAL DEBT SECURITIES

            The Debt Securities of a series may be issued in whole or in part in
the form of one or more fully registered global securities (a "Registered Global
Security"). Each Registered Global Security will be registered in the name of a
depository (the "Depository") or a nominee for the Depository or nominee or a
custodian therefor and will bear a legend regarding the restrictions on
exchanges and registration of transfer thereof referred to below and any such
other matters as may be provided for pursuant to the Indenture. In such a case,
one or more Registered Global Securities will be issued in a denomination or
aggregate denominations equal to the portion of the aggregate principal amount
of outstanding Debt Securities of the series to be represented by such
Registered Global Security or Securities. See Section 3.3 of the Indenture.
Unless and until it is exchanged in whole or in part for Debt Securities in
definitive certificated form, a Registered Global Security may not be registered
for transfer or exchange except as a whole by the Depositary for such Registered
Global Security to a nominee of such Depositary or by a nominee of such
Depositary to such Depositary or another nominee of such Depositary or by such
Depositary or any such nominee to a successor Depositary for such series or a
nominee of such successor Depositary and except in the circumstances described
in the applicable Prospectus Supplement. See Section 3.5 of the Indenture.

            The specific terms of the depositary arrangement with respect to any
portion of a series of Debt Securities to be represented by a Registered Global
Security will be described in the applicable Prospectus Supplement. The
Corporation expects that the following provisions will apply to depositary
arrangements.

            Upon the issuance of any Registered Global Security, and the deposit
of such Registered Global Security with or on behalf of the Depositary for such
Registered Global Security, the Depositary will credit, on its book-entry
registration and transfer system, the respective principal amounts of the Debt
Securities represented by such Registered Global Security to the accounts of
institutions ("participants") that have accounts with the Depositary or its
nominee. The accounts to be credited will be designated by the underwriters or
agents engaging in the distribution of such Debt Securities or by the
Corporation, if such Debt Securities are offered and sold directly by the
Corporation. Ownership of beneficial interests in a Registered Global Security
will be limited to participants or persons that may hold interests through
participants. Ownership of beneficial interests by participants in such
Registered Global Security will be shown on, and the transfer of such beneficial
interests will be effected only through, records maintained by the Depositary
for such Registered Global Security or by its nominee. Ownership of beneficial
interests in such Registered Global Security by persons that hold through
participants will be shown on, and the transfer of such beneficial interests
within such participants will be effected only through, records 


                                       8
<PAGE>   11
maintained by such participants. The laws of some jurisdictions require that
certain purchasers of securities take physical delivery of such securities in
certificated form. The foregoing limitations and such laws may impair the
ability to own, transfer or pledge beneficial interests in such Registered
Global Securities.

            So long as the Depositary for a Registered Global Security, or its
nominee, is the registered owner of such Registered Global Security, such
Depositary or such nominee, as the case may be, will be considered the sole
owner or holder of the Debt Securities represented by such Registered Global
Security for all purposes under the Indenture. See Section 3.8 of the Indenture.
Unless otherwise specified in the applicable Prospectus Supplement and except as
specified below, owners of beneficial interests in such Registered Global
Security will not be entitled to have Debt Securities of the series represented
by such Registered Global Security registered in their names, will not receive
or be entitled to receive physical delivery of Debt Securities of such series in
certificated form and will not be considered the holders thereof for any
purposes under the Indenture. See Section 3.8 of the Indenture.

            Ownership of beneficial interests in a Global Security will be
limited to participants and to persons that may hold beneficial interests
through participants. Each person owning a beneficial interest in such
Registered Global Security must rely on the procedures of the Depositary and, if
such person is not a participant, on the procedures of the participant through
which such person owns its interest, to exercise any rights of a holder under
the Indenture. The Depositary may grant proxies and otherwise authorize
participants to give or take any request, demand, authorization, direction,
notice, consent, waiver or other action which a holder is entitled to give or
take under the Indenture. The Corporation understands that, under existing
industry practices, if the Corporation requests any action of holders or any
owner of a beneficial interest in such Registered Global Security desires to
give any notice or take any action a holder is entitled to give or take under
the Indenture, the Depositary for such Registered Global Security would
authorize the participants holding the relevant beneficial interests to give
such notice or take such action, and such participants would authorize
beneficial owners owning through such participants to give such notice or take
such action or would otherwise act upon the instructions of beneficial owners
owning through them.

            Unless otherwise specified in the applicable Prospectus Supplement,
payments with respect to principal, premium, if any, and interest, if any, on
Debt Securities represented by a Registered Global Security registered in the
name of a Depositary or its nominee will be made to such Depositary or its
nominee, as the case may be, as the registered owner of such Registered Global
Security.

            The Corporation expects that the Depositary for any Debt Securities
represented by a Registered Global Security, upon receipt of any payment of
principal, premium or interest in respect of such Registered Global Securities,
will immediately credit participants' accounts with payments in amounts
proportionate to their respective beneficial interests in the principal amount
of such Registered Global Security as shown on the records of such Depositary.
The Corporation also expects that payments by participants to owners of
beneficial interests in such Registered Global Security held through such
participants will be governed by standing instructions and customary practices,
as is now the case with the securities held for the accounts of customers
registered in "street names," and will be the responsibility of such
participants. Nevertheless, payments, transfers, exchanges and other matters
relating to beneficial interests in a Registered Global Security may be subject
to various policies and procedures adopted by the Depository from time to time.
None of the Corporation, the Trustee or any agent of the Corporation or the
Trustee shall have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interests of a
Registered Global Security, or for main-

                                       9
<PAGE>   12
taining, supervising or reviewing any records relating to such beneficial
ownership interests. See Section 3.8 of the Indenture.

            Unless otherwise specified in the applicable Prospectus Supplement,
if the Depositary for any Debt Securities represented by a Registered Global
Security notifies the Company that it is unwilling or unable to continue as
Depositary or ceases to be a clearing agency registered under the Exchange Act,
and a successor Depositary registered as a clearing agency under the Exchange
Act is not appointed by the Corporation within 90 days, the Corporation will
issue such Debt Securities in definitive certificated form in exchange for such
Registered Global Security. In addition, the Corporation may at any time and in
its sole discretion determine not to have any of the Debt Securities of a series
represented by one or more Registered Global Securities and, in such event, will
issue Debt Securities of such series in definitive certificated form in exchange
for all of the Registered Global Security or Securities representing such Debt
Securities. See Section 3.5 of the Indenture.

            The Debt Securities of a series may also be issued in whole or in
part in the form of one or more bearer global securities (a "Bearer Global
Security") that will be deposited with a depositary, or with a nominee for such
depositary, identified in the applicable Prospectus Supplement. Any such Bearer
Global Securities may be issued in temporary or permanent form. See Section 3.4
of the Indenture. The specific terms and procedures, including the specific
terms of the depositary arrangement, with respect to any portion of a series of
Debt Securities to be represented by one or more Bearer Global Securities will
be described in the applicable Prospectus Supplement.

CONSOLIDATION, MERGER OR SALE BY THE CORPORATION

            The Corporation shall not consolidate with or merge into any other
corporation or transfer or lease all or substantially all of its assets to any
person, unless (i) the person formed by or surviving any such consolidation or
merger (if other than the Corporation) or to which such transfer or lease shall
have been made is a corporation organized and existing under the laws of the
United States, any state thereof or the District of Columbia and expressly
assumes all of the obligations of the Corporation under the Debt Securities and
under the Indenture, and (ii) immediately after giving effect to such
transaction, no Default or Event of Default exists. Upon any such consolidation,
merger or sale, the successor corporation formed by such consolidation, or into
which the Corporation is merged or to which such sale is made, shall succeed to,
and be substituted for the Corporation under the Indenture and under the Debt
Securities. See Section 7.1 of the Indenture.

EVENTS OF DEFAULT, NOTICE AND CERTAIN RIGHTS ON DEFAULT

            The Indenture provides that, if an Event of Default specified
therein occurs with respect to the Debt Securities of any series and is
continuing, the Trustee for such series or the holders of 25% in aggregate
principal amount of all of the outstanding Debt Securities of that series, by
written notice to the Corporation (and to the Trustee for such series, if notice
is given by such holders of Debt Securities), may declare the principal of (or,
if the Debt Securities of that series are Original Issue Discount Securities or
Indexed Securities, such portion of the principal amount specified in the
Prospectus Supplement) and accrued interest on all the Debt Securities of that
series to be due and payable. See Section 5.2 of the Indenture.

            Except as otherwise provided in a Prospectus Supplement relating to
the Debt Securities of a particular series, Events of Default with respect to
Debt Securities of any series are defined in


                                       10
<PAGE>   13
the Indenture as being: (a) default in payment of any interest on any Debt
Security of that series or any coupon appertaining thereto or any additional
amount payable with respect to Debt Securities of such series as specified in
the applicable Prospectus Supplement when due and continuance of such default
for 30 days; (b) default in payment of principal, or premium, if any, at
maturity or on redemption or otherwise, or in the making of a mandatory sinking
fund payment of any Debt Securities of that series when due; (c) failure for 60
days after notice to the Corporation by the Trustee for such series, or by the
holders of 25% in aggregate principal amount of the Debt Securities of such
series then outstanding, to comply in any material respect with any other
agreement in the Debt Securities of that series, in the Indenture or in any
supplemental indenture or board resolution referred to therein under which the
Debt Securities of that series may have been issued; and (d) certain events of
bankruptcy, insolvency or reorganization of the Corporation. See Section 5.1 of
the Indenture. Events of Default with respect to a specified series of Debt
Securities may be added to the Indenture and, if so added, will be described in
the applicable Prospectus Supplement. See Sections 3.1 and 5.1(7) of the
Indenture.

            The Indenture provides that the Trustee will, within 90 days after
the occurrence of a Default with respect to the Debt Securities of any series,
give to the holders of the Debt Securities of that series notice of all Defaults
known to it unless such Default shall have been cured or waived; provided that
except in the case of a Default in payment on the Debt Securities of that 
series, the Trustee may withhold the notice if and so long as a Responsible
Officer in good faith determines that withholding such notice is in the
interests of the holders of the Debt Securities of that series. See Section 6.6
of the Indenture. "Default" means any event which is, or after notice or passage
of time or both, would be, an Event of Default. See Section 1.1 of the
Indenture.

            The Indenture provides that the holders of a majority in aggregate
principal amount of the outstanding Debt Securities of each series affected
(with each such series voting as a class) may, subject to certain limited
conditions, direct the time, method and place of conducting any proceeding for
any remedy available to the Trustee for such series, or exercising any trust or
power conferred on such Trustee. See Section 5.8 of the Indenture.

            The Indenture includes a covenant that the Corporation will file
annually with the Trustee a certificate as to the Corporation's compliance with
all conditions and covenants of the Indenture. See Section 9.7 of the Indenture.

            The holders of a majority in aggregate principal amount outstanding
of any series of Debt Securities by written notice to the Trustee may waive, on
behalf of the holders of all Debt Securities of such series, any past Default or
Event of Default with respect to that series and its consequences except (i) a
Default or Event of Default in the payment of the principal of, premium, if any,
or interest, if any, on any Debt Security of such series or (ii) in respect of a
covenant or provision of the Indenture which cannot under the terms of the
Indenture be amended or modified without the consent of the holder of each
outstanding Debt Security of such series adversely affected. See Section 5.7 of
the Indenture.

CERTAIN COVENANTS OF THE CORPORATION

            Limitation on Liens. The Indenture provides that the Corporation
will not, and will not permit any Restricted Subsidiary (as defined) to, (a)
issue, assume or guarantee any indebtedness for money borrowed ("Debt") if such
Debt is secured by a mortgage (as defined) upon, or (b) directly or indirectly
secure any outstanding Debt by a mortgage upon, any Principal Property (as
defined) now owned or hereafter acquired, without effectively providing that the
Securities shall be secured equally and ratably


                                       11
<PAGE>   14
with such Debt, except that the foregoing restrictions shall not apply to (i)
mortgages on any Principal Property acquired, constructed or improved by the
Corporation or any Restricted Subsidiary after the date of the Indenture to
secure or provide for the payment of the purchase price or cost thereof incurred
after the date of the Indenture, or existing mortgages on property acquired,
provided such mortgages shall not apply to any property theretofore owned by the
Corporation or any Restricted Subsidiary other than theretofore unimproved real
property, (ii) mortgages on any Principal Property acquired from a corporation
merged with or into the Corporation or a Restricted Subsidiary, (iii) mortgages
to secure Debt of a Restricted Subsidiary to the Corporation or another
Restricted Subsidiary, (iv) any extension, renewal or replacement (or successive
extensions, renewals or replacements), in whole or in part, of any mortgage
referred to in the foregoing clauses (i) to (iii), inclusive, (v) the sale or
other transfer of any interest in property of the character commonly referred to
as a "production payment," and (vi) mortgages in favor of governmental bodies to
secure advance or progress payments pursuant to any contract or statute or
indebtedness incurred for the purpose of financing the purchase price or cost of
constructing or improving the property subject thereto. See Section 9.9 of the
Indenture.

            Notwithstanding the foregoing, the Corporation and any Restricted
Subsidiary may, without securing the Securities, issue, assume or guarantee
secured Debt (which would otherwise be subject to the foregoing restrictions) in
an aggregate amount which, together with all other such Debt of the Corporation
and its Restricted Subsidiaries and the Attributable Debt (as defined) in
respect of Sale and Lease-Back Transactions (as defined) existing at such time
(other than Sale and Lease-Back Transactions in which the property involved
would have been permitted to be mortgaged under the preceding paragraph, or the
proceeds of which have been applied to the retirement of long-term
indebtedness), does not at the time exceed 15% of the shareholders' equity in
the Corporation as shown on the consolidated balance sheet contained in the
latest annual report to shareholders of the Corporation. See Section 9.9 of the
Indenture.

            Sale and Lease-Back Transactions. (a) Sale and Lease-Back
Transactions (as defined) by the Corporation or any Restricted Subsidiary are
prohibited unless (i) the Corporation or such Restricted Subsidiary would be
entitled to incur Debt secured by a mortgage on the property to be leased
without equally and ratably securing the Securities or (ii) the Corporation
applies an amount equal to the fair value of the property sold to the retirement
of long-term indebtedness of the Corporation. Sale and Lease-Back Transactions
do not include arrangements with governmental bodies entered into for the
purpose of financing the purchase price or the cost of constructing or improving
the property subject thereto. See Section 9.10 of the Indenture.

            (b) Notwithstanding the provisions of the preceding paragraph (a),
the Corporation or any Restricted Subsidiary may enter into any Sale and
Lease-Back Transaction which would otherwise be subject to the foregoing
restrictions if the amount of the Attributable Debt in respect of Sale and
Lease-Back Transactions for such transaction, together with all secured Debt of
the Corporation and its Restricted Subsidiaries and all other Attributable Debt
in respect of Sale and Lease-Back Transactions existing at such time (other than
Sale and Lease-Back Transactions permitted because the Corporation would be
entitled to incur Debt secured by a mortgage on the property to be leased
without equally and ratably securing the Securities and other than Sale and
Lease-Back Transactions the proceeds of which have been applied in accordance
with clause (ii) of the preceding paragraph (a)), does not at the time exceed
15% of the shareholders' equity in the Corporation and its consolidated
subsidiary companies, as shown on the audited consolidated balance sheet
contained in the latest annual report to shareholders of the Corporation. See
Section 9.10 of the Indenture.



                                       12
<PAGE>   15
            The term "Principal Property" means certain mineral properties and
any concentrator, smelter, refinery or rod mill located within the United States
of America or its territories or possessions, of the Corporation or any
Restricted Subsidiary (or any capital stock or indebtedness of any Restricted
Subsidiary which owns any such property) except any such property, facility (or
Restricted Subsidiary) which the Board of Directors by resolution declares is
not of material importance to the total business conducted by the Corporation
and its Restricted Subsidiaries as an entity. See Section 9.9 of the Indenture.

            The term "Attributable Debt" means, as of any particular time, the
present value, discounted at a rate per annum equal to the weighted average of
the interest rate(s) of the outstanding Debt Securities, or, in the case of
Original Issue Discount Securities (as defined), the Yields to Maturity (as
defined) (compounded semi-annually), of the rental payments (not including
amounts payable by the lessee for maintenance, property taxes and insurance) due
during the remaining term of any lease (including any period for which such
lease has been extended or may, at the option of the lessor, be extended). See
Section 9.9 of the Indenture.

            The term "subsidiary" means any corporation of which at least a
majority of the stock having ordinary voting power for the election of directors
of such corporation is at the time directly or indirectly owned by the
Corporation. See Section 1.1 of the Indenture. The term "Restricted Subsidiary"
means (a) any subsidiary which owns or leases, directly or indirectly, a
Principal Property, and (b) any subsidiary which owns, directly or indirectly,
any stock or indebtedness of a Restricted Subsidiary; except that the term
"Restricted Subsidiary" shall not include (i) any subsidiary engaged primarily
in financing receivables, making loans, extending credit or other activities of
a character conducted by a finance company, or (ii) any subsidiary (A)
which conducts substantially all of its business outside the United States
of America or its territories and possessions or (B) the principal assets of
which are stock or indebtedness of corporations which conduct substantially all
of their business outside the United States of America and its territories and
possessions. See Section 9.9 of the Indenture.

MODIFICATION OF THE INDENTURE

            The Indenture contains provisions permitting the Corporation and the
Trustee to enter into one or more supplemental indentures without the consent of
the holders of any of the Debt Securities in order (i) to evidence the
succession of another corporation to the Corporation and the assumption of the
covenants of the Corporation by a successor to the Corporation; (ii) to add to
the covenants of the Corporation or surrender any right or power of the
Corporation; (iii) to add additional Events of Default with respect to any
series of Debt Securities; (iv) to add or change any provisions of the Indenture
to such extent as necessary to facilitate the issuance of Debt Securities in
bearer form; (v) to change or eliminate any provision affecting only Debt
Securities not yet issued; (vi) to secure the Debt Securities; (vii) to
establish the form or terms of Debt Securities; (viii) to evidence and provide
for successor Trustees or to add or change any provisions to such extent as
necessary to permit or facilitate the appointment of a separate Trustee or
Trustees for specific series of Debt Securities; (ix) if allowed without penalty
under applicable laws and regulations, to permit payment in respect of Debt
Securities in bearer form in the United States; (x) to correct any defect or
supplement any inconsistent provisions or to make any other provisions with
respect to matters or questions arising under the Indenture, provided that such
action does not adversely affect the interests of any holder of Debt Securities
of any series; or (xi) to cure any ambiguity or correct any mistake. See Section
8.1 of the Indenture.

            The Indenture also contains provisions permitting the Corporation
and the Trustee, with the consent of the holders of a majority in aggregate
principal amount of the outstanding Debt Securities affected by such
supplemental indenture (with the Debt Securities of each series voting as a
class), to execute supplemental indentures adding any provisions to or changing
or eliminating any of the provisions of the Indenture or any supplemental
indenture or modifying the rights of the holders of Debt Securities of such
series, except that no such supplemental indenture may, without the consent of
the holder of each Debt Security so affected, (i) change the time for payment of
principal or premium, if any, or interest on any Debt Security; (ii) reduce the
principal of, or any installment of principal of, or premium, if any, or
interest on any Debt Security, or change the manner in which the amount of any
of the foregoing is determined; (iii) reduce the interest rate, the amount of
principal or the amount of premium, if any, payable upon the redemption of any
Debt Security; (iv) reduce the amount of principal payable upon acceleration of
the maturity of any Original Issue Discount or Indexed Security; (v) change the
currency (including composite currency) or currency unit in which any Debt
Security or any premium or interest thereon is payable; (vi) impair the right to
institute suit for the enforcement of any payment on or with respect to any Debt
Security; (vii) reduce the percentage in principal amount of the outstanding
Debt Securities affected thereby the consent of whose holders is required for
modification or amendment of the Indenture or for waiver of compliance with
certain provisions of the Indenture or for waiver of certain defaults; (viii)
change the obligation of the Corporation to maintain an office or agency in the
places and for the purposes specified in the Indenture; or (ix) modify the
provisions relating to waiver of certain defaults or any of the foregoing
provisions. See Section 8.2 of the Indenture.

DEFEASANCE AND COVENANT DEFEASANCE

            If indicated in the Prospectus Supplement, the Corporation may elect
either (i) to defease and be discharged from any and all obligations with
respect to the Debt Securities of or within any series (except as otherwise
provided in the Indenture) ("defeasance") or (ii) to be released from its
obligations with respect to certain covenants applicable to the Debt Securities
of or within any series ("covenant defeasance"), upon the deposit with the
Trustee (or other qualifying trustee), in trust for such purpose, of money
and/or Government Obligations which through the payment of principal and
interest in accordance with their terms will provide money in an amount
sufficient, without reinvestment, to pay the principal of and any premium or
interest on such Debt Securities to Maturity or redemption, as the case may be,
and any mandatory sinking fund or analogous payments thereon. As a condition to
defeasance or covenant defeasance, the Corporation must deliver to the Trustee
an Opinion of Counsel to the effect that the Holders of such Debt Securities
will not recognize income, gain or loss for Federal income tax purposes as a
result of such defeasance or covenant defeasance and will be subject to Federal
income tax on the same amounts and in the same manner and at the same times as
would have been the case if such defeasance or covenant defeasance had not
occurred. Such Opinion of Counsel, in the case of defeasance under clause (i)
above, must refer to and be based upon a ruling of the Internal Revenue Service
or a change in applicable Federal income tax law occurring after the date of the
Indenture. In addition, defeasance or covenant defeasance shall not result in a
breach or Default or Event of Default under the Indenture or a default under any
other material agreement or instrument to which the Corporation is a party or by
which it is bound. See Article 4 of the Indenture. If indicated in the
Prospectus Supplement, in addition to obligations of the United States or an
agency or instrumentality thereof, Government Obligations may include
obligations of the government or an agency or instrumentality of the government
issuing the currency or currency unit in which Debt Securities of such series
are payable. See Section 3.1 of the Indenture.


                                       14
<PAGE>   17
            The Corporation may exercise its defeasance option with respect to
such Debt Securities notwithstanding its prior exercise of its covenant
defeasance option. If the Corporation exercises its defeasance option, payment
of such Debt Securities may not be accelerated because of a Default or an Event
of Default. If the Corporation exercises its covenant defeasance option, payment
of such Debt Securities may not be accelerated by reason of an Event of Default
with respect to the covenants to which such covenant defeasance is applicable.
However, if such acceleration were to occur by reason of another Event of
Default, the realizable value at the acceleration date of the money and
Government Obligations in the defeasance trust could be less than the principal
and interest then due on such Debt Securities, in that the required deposit in
the defeasance trust is based upon scheduled cash flow rather than market value,
which will vary depending upon interest rates and other factors.

NOTICES

            Notices to holders of registered Debt Securities will be given by
mail to the addresses of such holders as they may appear in the Register. See
Section 1.6 of the Indenture

TITLE

            The Corporation, the Trustee and any agent of the Corporation or the
Trustee may treat the Person in whose name a Debt Security is registered as the
absolute owner thereof (whether or not such Debt Security may be overdue) for
the purpose of receiving payment and for all other purposes. See Section 3.8 of
the Indenture.

GOVERNING LAW

            The Indenture and the Debt Securities will be governed by, and
construed in accordance with, the laws of the State of New York. See Section
1.11 of the Indenture.

THE TRUSTEE

            The Chase Manhattan Bank is the Trustee under the Indenture. The
Corporation may also maintain banking and other commercial relationships with
the Trustee and its affiliates in the ordinary course of business.


                              PLAN OF DISTRIBUTION

            The Corporation may sell any of the Debt Securities being offered
hereby in any one or more of the following ways from time to time: (i) through
agents; (ii) to or through underwriters; (iii) through dealers; and (iv)
directly by the Corporation to purchasers.

            The distribution of the Debt Securities may be effected from time to
time in one or more transactions at a fixed price or prices, which may be
changed, at market prices prevailing at the time of sale, at prices related to
such prevailing market prices or at negotiated prices.

            Offers to purchase Debt Securities may be solicited by agents
designated by the Corporation from time to time. Any such agent involved in the
offer or sale of the Debt Securities in respect of which this Prospectus is
delivered will be named, and any commissions payable by the Corporation to such


                                       15
<PAGE>   18
agent will be set forth, in the applicable Prospectus Supplement. Unless
otherwise indicated in such Prospectus Supplement, any such agent will be acting
on a reasonable best efforts basis for the period of its appointment. Any such
agent may be deemed to be an underwriter, as that term is defined in the
Securities Act, of the Debt Securities so offered and sold.

            If Debt Securities are sold by means of an underwritten offering,
the Corporation will execute an underwriting agreement with an underwriter or
underwriters at the time an agreement for such sale is reached, and the names of
the specific managing underwriter or underwriters, as well as any other
underwriters, and the terms of the transaction, including commissions, discounts
and any other compensation of the underwriters and dealers, if any, will be set
forth in the Prospectus Supplement which will be used by the underwriters to
make resales of the Debt Securities in respect of which this Prospectus is
delivered to the public. If underwriters are utilized in the sale of the Debt
Securities in respect of which this Prospectus is delivered, the 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 fixed public offering prices or at varying prices determined by
the underwriter at the time of sale. Debt Securities may be offered to the
public either through underwriting syndicates represented by managing
underwriters or directly by the managing underwriters. If any underwriter or
underwriters are utilized in the sale of the Debt Securities, unless otherwise
indicated in the Prospectus Supplement, the underwriting agreement will provide
that the obligations of the underwriters are subject to certain conditions
precedent and that the underwriters with respect to a sale of Debt Securities
will be obligated to purchase all such Debt Securities if any are purchased.

            If a dealer is utilized in the sale of the Debt Securities in
respect of which this Prospectus is delivered, the Corporation will sell such
Debt Securities to the dealer as principal. The dealer may then resell such Debt
Securities to the public at varying prices to be determined by such dealer at
the time of resale. Any such dealer may be deemed to be an underwriter, as such
term is defined in the Securities Act, of the Debt Securities so offered and
sold. The name of the dealer and the terms of the transaction will be set forth
in the Prospectus Supplement relating thereto.

            Offers to purchase Debt Securities may be solicited directly by the
Corporation and the sale thereof may be made by the Corporation directly to
institutional investors or others, who may be deemed to be underwriters within
the meaning of the Securities Act with respect to any resale thereof. The terms
of any such sales will be described in the Prospectus Supplement relating
thereto.

            Agents, underwriters and dealers may be entitled under relevant
agreements to indemnification or contribution by the Corporation against certain
liabilities, including liabilities under the Securities Act.

            Each series of Debt Securities will be a new issue with no
established trading market. The Corporation may elect to list any series of Debt
Securities on an exchange, but the Corporation shall not be obligated to do so.
It is possible that one or more underwriters may make a market in a series of
Debt Securities, but will not be obliged to do so and may discontinue any market
making at any time without notice. Therefore, no assurance can be given as to
the liquidity of the trading market for the Debt Securities.

            In order to facilitate the offering of the Debt Securities, any
underwriters or agents, as the case may be, involved in the offering of such
Debt Securities may engage in transactions that stabilize, maintain or otherwise
affect the price of the Debt Securities or any other securities the prices of
which may be used to determine payments on such Debt Securities. Specifically,
the underwriters or agents, 

                                       16
<PAGE>   19
as the case may be, may overallot in connection with the offering, creating a
short position in such Debt Securities for their own account. In addition, to
cover overallotments or to stabilize the price of such Debt Securities or any
such other securities, the underwriters or agents, as the case may be, may bid
for, and purchase, such Debt Securities or any such other securities in the open
market. Finally, in any offering of such Debt Securities through a syndicate of
underwriters, the underwriting syndicate may reclaim selling concessions allowed
to an underwriter or a dealer for distributing such Debt Securities in the
offering if the syndicate repurchases previously distributed Debt Securities in
transactions to cover syndicate short positions, in stabilization transactions
or otherwise. Any of these activities may stabilize or maintain the market price
of the Debt Securities above independent market levels. The underwriters or
agents, as the case may be, are not required to engage in these activities, and
may end any of these activities at any time.

            Agents, underwriters and dealers may be customers of, engage in
transactions with, or perform services for, the Corporation and its subsidiaries
in the ordinary course of business.

            Debt Securities may also be offered and sold, if so indicated in the
Prospectus Supplement, in connection with a remarketing upon their purchase, in
accordance with a redemption or repayment pursuant to their terms, or otherwise,
by one or more firms ("remarketing firms"), acting as principals for their own
accounts or as agents for the Corporation. Any remarketing firm will be
identified and the terms of its agreement, if any, with the Corporation and its
compensation will be described in the Prospectus Supplement. Remarketing firms
may be deemed to be underwriters, as such term is defined in the Securities Act,
in connection with the Debt Securities remarketed thereby. Remarketing firms may
be entitled under agreements which may be entered into with the Corporation to
indemnification or contribution by the Corporation against certain civil
liabilities, including liabilities under the Securities Act, and may be
customers of, engage in transactions with or perform services for the
Corporation in the ordinary course of business.

            If so indicated in the applicable Prospectus Supplement, the
Corporation may authorize agents, underwriters or dealers to solicit offers by
certain institutions to purchase Debt Securities from the Corporation at the
public offering prices set forth in the applicable Prospectus Supplement
pursuant to delayed delivery contracts ("Contracts") providing for payment and
delivery on a specified date or dates. A commission indicated in the applicable
Prospectus Supplement will be paid to underwriters, dealers and agents
soliciting purchases of Debt Securities pursuant to Contracts accepted by the
Corporation.


                                  LEGAL MATTERS

            Unless otherwise indicated in the applicable Prospectus Supplement,
the validity of any Debt Securities offered hereby will be passed upon for the
Corporation by Debevoise & Plimpton, 875 Third Avenue, New York, New York 10022.


                                     EXPERTS

            The financial statements incorporated in this Prospectus by
reference to the Annual Report on Form 10-K of the Corporation for the year
ended December 31, 1996 have been so incorporated in reliance on the report of
Price Waterhouse LLP, independent accountants, given on the authority of said
firm as experts in auditing and accounting.

            With respect to the unaudited consolidated financial information of
the Corporation for the three-month periods ended March 31, 1997 and 1996 and
the six-month periods ended June 30, 1997 and 1996 incorporated by reference in
this Prospectus, Price Waterhouse LLP reported that they have applied limited
procedures in accordance with professional standards for a review of such
information. However, their separate reports dated April 9, 1997 and July 10,
1997 incorporated by reference herein, state that they did not audit and they do
not express an opinion on that unaudited consolidated financial information.
Price Waterhouse LLP has not carried out any significant or additional audit
tests beyond those which would have been necessary if their report had not been
included. Accordingly, the degree of reliance on their report on such
information should be restricted in light of the limited nature of the review
procedures applied. Price Waterhouse LLP is not subject to the liability
provisions of section 11 of the Securities Act of 1933 for their report on the
unaudited consolidated financial information because that report is not a
"report" or a "part" of the registration statement prepared or certified by
Price Waterhouse LLP within the meaning of sections 7 and 11 of the Act.

            The consolidated financial statements of the Corporation included in
any subsequent Annual Report of the Corporation on Form 10-K and incorporated by
reference in this Prospectus will have been examined by the independent
accountants whose report thereon appears in such Annual Report. Such
consolidated financial statements of the Corporation shall be deemed to be
incorporated herein from the date of filing of the applicable report on Form
10-K in reliance on the reports of such independent accountants, given on the
authority of such firm as experts in auditing and accounting.

Item 15. Indemnification of Directors and Officers.
         ------------------------------------------
            With certain limitations, Sections 721 through 726 of the Business
Corporation Law of the State of New York permit a corporation to indemnify any
of its directors or officers made, or threatened to be made, a party to an
action or proceeding by reason of the fact that such person was a director or
officer of such corporation unless a judgment or other final adjudication
adverse to the director or officer establishes that his or her acts were
committed in bad faith or were the result of active and deliberate dishonesty
and were material to the cause of action so adjudicated, or that he or she
personally gained in fact financial profit or other advantage to which he or she
was not legally entitled.

            The By-Laws of the Corporation provide that (a) the Corporation
shall indemnify any person made, or threatened to be made, a party to an action
or proceeding other than one by or in the right of the Corporation to procure a
judgment in its favor, whether civil or criminal, including an action by or in
the right of any other corporation of any type or kind, domestic or foreign, or
any partnership, joint venture, trust, employee benefit plan or other
enterprise, which any Director or officer of the Corporation served in any
capacity at the request of the Corporation, by reason of the fact that he, his
testator or intestate, is or was a Director or officer of the Corporation, or is
or was serving such other corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise in any capacity, against judgments,
fines, amounts paid in settlement and expenses (including attorneys' fees)
incurred in connection with such action or proceeding, or any appeal therein,
provided that no indemnification may be made to or on behalf of such person if
(i) his acts were committed in bad faith or were the result of his active and
deliberate dishonesty and were material to such action or proceeding or (ii) he
personally gained in fact a financial profit or other advantage to which he was
not legally entitled.

            (b) The Corporation shall indemnify any person made, or threatened
to be made, a party to an action by or in the right of the Corporation to
procure a judgment in its favor by reason of the fact that 


                                      II-1
<PAGE>   22
he, his testator or intestate, is or was a Director or officer of the
Corporation, or is or was serving at the request of the Corporation as a
Director or officer of any other corporation of any type or kind, domestic or
foreign, or of any partnership, joint venture, trust, employee benefit plan or
other enterprise, against judgments, amounts paid in settlement and expenses
(including attorneys' fees) incurred in connection with such action, or any
appeal therein, provided that no indemnification may be made to or on behalf of
such person if (i) his acts were committed in bad faith or were the result of
his active and deliberate dishonesty and were material to such action or (ii) he
personally gained in fact a financial profit or other advantage to which he was
not legally entitled.

            The directors and officers of the Corporation are covered by
insurance policies maintained by the Corporation at its expense insuring the
directors and officers against certain liabilities which might be incurred by
them in such capacities including liabilities arising under the Securities Act
of 1933.

            On May 4, 1988, the shareholders approved an amendment to the
Corporation's Certificate of Incorporation relating to liability of the
directors of the Corporation by adding the following new Article SEVENTH:

            "SEVENTH: The personal liability of the Directors of the Corporation
for any breach of duty in such capacity is hereby eliminated and limited to the
fullest extent permitted by Section 402(b) of the New York Business Corporation
Law as the same may be amended from time to time."

            Section 402(b) of the Business Corporation Law of the State of New
York referred to in such new Article SEVENTH permits New York corporations to
eliminate or limit the personal liability of directors to the corporation or its
shareholders for damages for any breach of duty in such capacity except
liability (i) of a director (a) whose acts or omissions were in bad faith,
involved intentional misconduct or a knowing violation of law, (b) who
personally gained a financial profit or other advantage to which he or she was
not legally entitled or (c) whose acts violated certain other provisions of New
York law or (ii) for acts or omissions prior to July 23, 1987.

            The underwriters or agents on whose behalf the agreement listed as
Exhibit 1 to this Registration Statement will be executed will agree therein to
indemnify the Corporation's directors, officers and controlling persons against
certain liabilities which might arise under the Securities Act of 1933 from
information furnished to the Corporation by or on behalf of such underwriters
for use in the Registration Statement.

Item 17. Undertakings.
         -------------
(a) Rule 415 Offering.

      The undersigned registrant 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 the
      registration statement. Notwithstanding the foregoing, any increase or
      decrease in volume of securities offered (if the total dollar value of
      securities offered would not exceed that which was registered) and any
      deviation from the low or high end of the estimated maximum offering range
      may be reflected in the form of prospectus filed with the Commission
      pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
      price represent no more than a 20% change in the maximum aggregate
      offering price set forth in the "Calculation of Registration Fee" table in
      the effective registration statement; and

            (iii) To include any material information with respect to the plan
      of distribution not previously disclosed in the registration statement or
      any material change to such information in the 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 Corporation 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 therein, 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.

(b) Filings Incorporating Subsequent Exchange Act Documents by Reference.

            The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 that is incorporated by reference in the registration
statement 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.


                                      II-4

(c) Rule 430A Offering.
            The undersigned hereby undertakes that:

            (1) 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 Corporation pursuant to
      Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed
      to be part of this registration statement as of the time it was declared
      effective.

            (2) 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.

(d) Acceleration of Effectiveness.

            Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons, if any, of the registrant pursuant to the foregoing provisions, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Corporation of expenses incurred or paid by a director, officer or controlling
person of the Corporation 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 registrant 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 Act and will
be governed by the final adjudication of such issue.

execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgements of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where
such execution is by a signer acting in a capacity other than his




                                       16
<PAGE>   25
individual capacity, such certificate or affidavit shall also constitute
sufficient proof of his authority. The fact and date of the execution of any
such instrument or writing, or the authority of the Person executing the same,
may also be proved in any other manner which the Trustee deems sufficient.

                  (c) The ownership of Bearer Securities may be proved by the
production of such Bearer Securities or by a certificate executed by any trust
company, bank, banker or other depository, wherever situated, if such
certificate shall be deemed by the Trustee to be satisfactory, showing that at
the date therein mentioned such Person had on deposit with such depository, 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 Trustee to be
satisfactory. The Trustee and the Company may assume that such ownership of any
Bearer Security continues until (i) another such certificate or affidavit
bearing a later date issued in respect of the same Bearer Security is produced,
(ii) such Bearer Security is produced to the Trustee by some other Person, (iii)
such Bearer Security is surrendered in exchange for a Registered Security or
(iv) such Bearer Security is no longer Outstanding. The ownership of Bearer
Securities may also be proved in any other manner which the Trustee deems
sufficient.

                  (d) The ownership of Registered Securities shall be proved by
the Register.

                  (e) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Trustee or
the Company in




                                       17
<PAGE>   26
reliance thereon, whether or not notation of such action is made upon such
Security.

                  (f) If the Company shall solicit from the Holders any request,
demand, authorization, direction, notice, consent, waiver or other Act, the
Company may, at its option, by or pursuant to a 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, but the Company shall have no obligation to do so. If such a
record date is fixed, such request, demand, authorization, direction, notice,
consent, waiver or other Act may be given before or after such record date, but
only the Holders of Registered Securities of record at the close of business on
such record date shall be deemed to be Holders for the purposes 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 on such record date
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.

                  Section 1.5. Notices, etc., to Trustee and Company. Any
request, demand, authorization, direction, notice, consent, waiver or Act of
Holders or other document provided or permitted by this Indenture to be made
upon, given or furnished to, or filed with,

                  (1) the Trustee by any Holder or by the Company shall be
         sufficient for every purpose hereunder (unless otherwise herein
         expressly provided) if in writing and mailed, first-class postage
         prepaid, to the Trustee at its Corporate Trust Office, Attention:
         Corporate Trust Administration, or




                                       18
<PAGE>   27
                  (2) the Company by the Trustee or by any Holder shall be
         sufficient for every purpose hereunder (unless otherwise herein
         expressly provided) if in writing and mailed, first-class postage
         prepaid, to the Company addressed to it at Phelps Dodge Corporation,
         2600 N. Central Avenue, Phoenix, Arizona 85004-3014, Attention: General
         Counsel or at any other address previously furnished in writing to the
         Trustee by the Company.

                  Section 1.6. Notice to Holders; Waiver. Where this Indenture
provides for notice to Holders of any event, (i) if any of the Securities
affected by such event are Registered Securities, such notice to the Holders
thereof shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each such Holder
affected by such event, at his address as it appears in the Register, within the
time prescribed for the giving of such notice and, (ii) if any of the Securities
affected by such event are Bearer Securities, notice to the Holders thereof
shall be sufficiently given (unless otherwise herein or in the terms of such
Bearer Securities expressly provided) if published once in an Authorized
Newspaper in New York, New York, and in such other city or cities, if any, as
may be specified as contemplated by Section 3.1.

                  In any case where notice to Holders is given by mail, neither
the failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders of Registered Securities or the sufficiency of any notice to
Holders of Bearer Securities given as provided herein. In any case where notice
is given to Holders by publication, neither the failure to publish such notice,
nor any defect in any notice so published, shall affect the sufficiency of such
notice with respect to other Holders of Bearer Securities or the sufficiency of
any notice to Holders of Registered Securities given as provided herein. Any
notice mailed to a Holder in the manner herein prescribed shall be conclusively
deemed to have been




                                       19
<PAGE>   28
received by such Holder, whether or not such Holder actually receives such
notice.

                  If by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice as
provided above, then such notification as shall be made with the approval of the
Trustee shall constitute a sufficient notification for every purpose hereunder.
If it is impossible or, in the opinion of the Trustee, impracticable to give any
notice by publication in the manner herein required, then such publication in
lieu thereof as shall be made with the approval of the Trustee shall constitute
a sufficient publication of such notice.

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

                  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 equivalent of such
notice. Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

                  Section 1.7. Headings and Table of Contents. The Article and
Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

                  Section 1.8. Successor and Assigns. All covenants and
agreements in this Indenture by the Company shall bind its successor and
assigns, whether so expressed or not.

                  Section 1.9. Separability. In case any provision of this
Indenture or the Securities shall be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

                  Section 1.10. Benefits of Indenture. Nothing in this Indenture
or in the Securities, expressed or implied, shall give to any Person, other than
the parties hereto and their successors hereunder and the Holders, any benefit
or any legal or equitable right, remedy or claim under this Indenture.

                  Section 1.11. Governing Law. THIS INDENTURE, THE SECURITIES
AND ANY COUPONS APPERTAINING THERETO SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. This Indenture is subject to
the Trust Indenture Act and if any provision hereof limits, qualifies or
conflicts with the Trust Indenture Act, the Trust Indenture Act shall control.

                  Section 1.12. Legal Holidays. In any case where any Interest
Payment Date, Redemption Date, sinking fund payment date, Stated Maturity or
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of any Security
or coupon other than a provision in the Securities of any series which
specifically states that such provision shall apply in lieu of this Section),
payment of principal, premium, if any, or interest need not be made at such
Place of Payment on such date, but may be made on the next succeeding Business
Day at such Place of Payment with the same force and effect as if made on such
date; provided that no interest shall accrue on the amount so payable for the
period from and after such Interest Payment Date, Redemption Date, sinking fund
payment date, Stated Maturity or Maturity, as the case may be.

required to comply with the rules of any securities exchange or as may,
consistently herewith, be determined by the officers executing such Securities
and coupons, if any, as evidenced by their execution of the Securities and
coupons, if any. If temporary Securities of any series are issued as permitted
by Section 3.4, the form thereof also shall be established as provided in the
preceding sentence. If the forms of Securities and coupons, if any, of any
series are established by, or by action taken pursuant to, a Board Resolution, a
copy of the Board Resolution together with an appropriate record of any such
action taken pursuant thereto, including a copy of the approved form of
Securities or coupons, if any, shall be certified by the Corporate Secretary or
an Assistant Secretary of the Company and delivered to the Trustee at or prior

within a series are issuable in whole or in part in global form, any such
Security may provide that it shall represent the aggregate or specified amount
of Outstanding Securities from time to time endorsed thereon and may also
provide that the aggregate amount of Out standing Securities represented thereby
may from time to time be reduced to reflect exchanges. Any endorsement of a
Security in global form to reflect the amount, or any increase or decrease in
the amount, or changes in the rights of Holders, of Outstanding Securities
represented thereby, shall be made in such manner and by such Person or Persons
as shall be specified therein or in the Company Order to be delivered to the
Trustee pursuant to Section 3.3 or 3.4. Subject to the provisions of Section 3.3
and, if applicable, Section 3.4, the Trustee shall deliver and redeliver any
security in permanent global form in the manner and upon instructions given by
the Person or Persons specified therein or in the applicable Company Order. Any
instructions by the Company with respect to endorsement or delivery or
redelivery of a Security in global form shall be in writing but need not comply
with Section 1.2 hereof and need not be accompanied by an Opinion of Counsel.

apply to any Security in global form if such Security was never issued and sold
by the Company and the Company delivers to the Trustee the Security in global
form together with written instructions (which need not comply with Section 1.2
and need not be accompanied by an Opinion of Counsel) with regard to the
reduction in the principal amount of Securities represented thereby, together
with the written statement contemplated by the last paragraph of Section 3.3.

                  Notwithstanding the provisions of Section 2.1 and 3.7, unless
otherwise specified as contemplated by Section 3.1, payment of principal of,
premium, if any, and interest on any Security in permanent global form shall be

         Indenture hereinafter referred to and is registered in the name of a

         Security may not be transferred except as a whole by the Depositary to
         a nominee of the Depositary or by a nominee of the Depositary to the
         Depositary or another nominee of the Depositary or by the Depositary or
         any such nominee to a successor Depositary or a nominee of such

                  (24) any other terms of the series (which terms shall not be
         inconsistent with the provisions of this Indenture) including any terms
         which may be required by or advisable under United States laws or
         regulations or advisable in connection with the marketing of Securities
         of the series; and

                  (25) the designation of the initial Depositary.

                  (c) All Securities of any one series and coupons, if any,
appertaining to any Bearer Securities of such series shall be substantially
identical except, in the case of Registered Securities, as to denomination and
except as may




                                       29

otherwise be provided (i) by a Board Resolution, (ii) by action taken pursuant
to a Board Resolution and (subject to Section 3.3) set forth, or determined in
the manner provided, in the related Officers' Certificate or (iii) in an
indenture supplemental hereto. All Securities of any one series need not be
issued at the same time and, unless otherwise provided, a series may be
reopened, without the consent of the Holders, for issuances of additional
Securities of such series.

                  (d) If any of the terms of the Securities of any series are
established by action taken pursuant to a Board Resolution, a copy of such Board
Resolution shall be certified by the Corporate Secretary or an Assistant
Secretary of the Company and delivered to the Trustee at or prior to the
delivery of the Officers' Certificate setting forth, or providing the manner for
determining, the terms of the Securities of such series, and an appropriate
record of any action taken pursuant thereto in connection with the issuance of
any Securities of such series shall be delivered to the Trustee prior to the
authentication and delivery thereof.

                  Section 3.2. Denominations. Unless otherwise provided as
contemplated by Section 3.1, any Registered Securities of a series shall be
issuable in denominations of $1,000 and any integral multiple thereof and any
Bearer Securities of a series shall be issuable in the denomination of $5,000.

                  Section 3.3. Execution, Authentication, Delivery and Dating.
Securities shall be executed on behalf of the Company by two Officers. The
Company's seal shall be reproduced on the Securities. The signatures of any of
these officers on the Securities may be manual or facsimile. The coupons, if
any, of Bearer Securities shall bear the facsimile signature of two Officers.

                  Securities and coupons bearing the manual or facsimile
signatures of individuals who were at any time the




                                       30
<PAGE>   39
proper officers of the Company shall bind the Company, notwithstanding that such
individuals or any of them have ceased to hold such offices prior to the
authentication and delivery of such Securities or did not hold such offices at
the date of such Securities.

                  At any time and from time to time, the Company may deliver
Securities, together with any coupons appertaining thereto, of any series
executed by the Company to the Trustee for authentication, together with a
Company Order for the authentication and delivery of such Securities, and the
Trustee in accordance with the Company Order shall authenticate and deliver such
Securities; provided, however, that in the case of Securities offered in a
Periodic Offering, the Trustee shall authenticate and deliver such Securities
from time to time in accordance with such other procedures (including, without
limitation, the receipt by the Trustee of oral or electronic instructions from
the Company or its duly authorized agents, promptly confirmed in writing)
acceptable to the Trustee as may be specified by or pursuant to a Company Order
delivered to the Trustee prior to the time of the first authentication of
Securities of such series.

                  If the form or terms of the Securities of a series have been
established by or pursuant to one or more Board Resolutions as permitted by
Sections 2.1 and 3.1, in authenticating such Securities and accepting the
additional responsibilities under this Indenture in relation to such Securities,
the Trustee shall be entitled to receive, and (subject to section 315(a) through
(d) of the Trust Indenture Act) shall be fully protected in relying upon, an
Opinion of Counsel stating,

                  (1) if the forms of such Securities and any coupons have been
         established by or pursuant to a Board Resolution as permitted by
         Section 2.1, that such forms have been established in conformity with
         the provisions of this Indenture;




                                       31
<PAGE>   40
                  (2) if the terms of such Securities and any coupons have been
         established by or pursuant to a Board Resolution as permitted by
         Section 3.1, that such terms have been, or in the case of Securities of
         a series offered in a Periodic Offering, will be, established in
         conformity with the provisions of this Indenture, subject in the case
         of Securities offered in a Periodic Offering, to any conditions
         specified in such Opinion of Counsel; and

                  (3) that such Securities together with any coupons
         appertaining thereto, when authenticated and delivered by the Trustee
         and issued by the Company in the manner and subject to any conditions
         specified in such Opinion of Counsel, will constitute valid and legally
         binding obligations of the Company, enforceable in accordance with
         their terms, subject to bankruptcy, insolvency, fraudulent transfer,
         reorganization, moratorium and other similar laws of general
         applicability relating to or affecting the enforcement of creditors'
         rights and to general equity principles and except further as
         enforcement thereof may be limited by (A) requirements that a claim
         with respect to any Securities denominated other than in Dollars (or a
         Foreign Currency or currency unit judgment in respect of such claim) be
         converted into Dollars at a rate of exchange prevailing on a date
         determined pursuant to applicable law or (B) governmental authority to
         limit, delay or prohibit the making of payments in Foreign Currencies
         or currency units or payments outside the United States.

Notwithstanding that such form or terms have been so established, the Trustee
shall have the right to decline to authenticate such Securities if, in the
written opinion of counsel to the Trustee (which counsel may be an employee of
the Trustee), the issue of such Securities pursuant to this Indenture will
adversely affect the Trustee's own rights, duties or immunities under this
Indenture or otherwise in a manner which is not reasonably acceptable to the
Trustee.




                                       32
<PAGE>   41
Notwithstanding the generality of the foregoing, the Trustee will not be
required to authenticate Securities denominated in a Foreign Currency if the
Trustee reasonably believes that it would be unable to perform its duties with
respect to such Securities.

                  Notwithstanding the provisions of Section 3.1 and of the two
preceding paragraphs, if all of the Securities of any series are not to be
issued at one time, it shall not be necessary to deliver the Officers'
Certificate otherwise required pursuant to Section 3.1 or the Company Order and
Opinion of Counsel otherwise required pursuant to the two preceding paragraphs
in connection with the authentication of each Security of such series if such
documents, with appropriate modifications to cover such future issuances, are
delivered at or prior to the authentication upon original issuance of the first
Security of such series to be issued.

                  With respect to Securities of a series offered in a Periodic
Offering, the Trustee may rely, as to the authorization by the Company of any of
such Securities, the form and terms thereof and the legality, validity, binding
effect and enforceability thereof, upon the Opinion of Counsel and the other
documents delivered pursuant to Sections 2.1 and 3.1 and this Section, as
applicable, in connection with the first authentication of Securities of such
series.

                  If the Company shall establish pursuant to Section 3.1 that
the Securities of a series are to be issued in whole or in part in global form,
then the Company shall execute and the Trustee shall, in accordance with this
Section and the Company Order with respect to such series, authenticate and
deliver one or more Securities in global form that (i) shall represent and shall
be denominated in an amount equal to the aggregate principal amount of the
Outstanding Securities of such series to be represented by such Security or
Securities in global form, (ii) shall be




                                       33
<PAGE>   42
registered, if a Registered Security, in the name of the Depositary for such
Security or Securities in global form or the nominee of such Depositary, (iii)
shall be delivered by the Trustee to such Depositary or pursuant to such
Depositary's instruction and (iv) shall bear the legend set forth in Section
2.4.

                  Each Depositary designated pursuant to Section 3.1 for a
Registered Security in global form must, at the time of its designation and at
all times while it serves as Depositary, be a clearing agency registered under
the Securities Exchange Act of 1934 and any other applicable statute or
regulation. The Trustee shall have no responsibility to determine if the
Depositary is so registered. Each Depositary shall enter into an agreement with
the Trustee governing the respective duties and rights of such Depositary and
the Trustee with regard to Securities issued in global form.

                  Each Registered Security shall be dated the date of its
authentication and each Bearer Security shall be dated as of the date specified
as contemplated by Section 3.1.

                  No Security or coupon appertaining thereto shall be entitled
to any benefits under this Indenture or be valid or obligatory for any purpose
until authenticated by the manual signature of one of the authorized signatories
of the Trustee or an Authenticating Agent and no coupon shall be valid until the
Security to which it appertains has been so authenticated. Such signature upon
any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered under this Indenture and is
entitled to the benefits of this Indenture. Except as permitted by Section 3.6
or 3.7, the Trustee shall not authenticate and deliver any Bearer Security
unless all appurtenant coupons for interest then matured have been detached and
cancelled.




                                       34
<PAGE>   43
                  Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 3.9 together with a written statement (which need not comply
with Section 1.2 and need not be accompanied by an Opinion of Counsel) stating
that such Security has never been issued and sold by the Company, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall not be entitled to the benefits
of this Indenture.

                  Section 3.4. Temporary Securities. Pending the preparation of
definitive Securities of any series, the Company may execute and, upon Company
Order, the Trustee shall authenticate and deliver temporary Securities of such
series which are printed, lithographed, typewritten, mimeographed or otherwise
produced, in any authorized denomination, substantially of the tenor and form,
with or without coupons, of the definitive Securities in lieu of which they are
issued and with such appropriate insertions, omissions, substitutions and other
variations as the officers executing such Securities may determine, as
conclusively evidenced by their execution of such Securities and coupons, if
any. In the case of Securities of any series, such temporary Securities may be
in global form, representing all or a portion of the Outstanding Securities of
such series.

                  Except in the case of temporary Securities in global form,
each of which shall be exchanged in accordance with the provisions thereof, if
temporary Securities of any series are issued, the Company will cause definitive
Securities of such series to be prepared without unreasonable delay. After
preparation of definitive Securities of such series, the temporary Securities of
such series shall be exchangeable for definitive Securities of such series upon
surrender of the temporary Securities of such series at the office or agency of
the Company pursuant to Section 9.2 in a Place of Payment for such series,


                                       35
<PAGE>   44
without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities of any series (accompanied by any unmatured coupons
appertaining thereto), the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of the same series of authorized denominations and of like
tenor; provided, however, that no definitive Bearer Security shall be delivered
in exchange for a temporary Registered Security; and provided further that no
definitive Bearer Security shall be delivered in exchange for a temporary Bearer
Security unless the Trustee shall have received from the person entitled to
receive the definitive Bearer Security a certificate substantially in the form
approved in the Board Resolutions relating thereto and such delivery shall occur
only outside the United States. 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 except as otherwise specified
as contemplated by Section 3.1.

                  Section 3.5. Registration, Transfer and Exchange. The Company
shall cause to be kept at the Corporate Trust Office of the Trustee or in any
office or agency to be maintained by the Company in accordance with Section 9.2
in a Place of Payment a register (the "Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Registered Securities and the registration of transfers of
Registered Securities. The Register shall be in written form or any other form
capable of being converted into written form within a reasonable time. The
Trustee is hereby appointed "Registrar" for the purpose of registering
Registered Securities and transfers of Registered Securities as herein provided.

                  Upon surrender for registration of transfer of any Registered
Security of any series at the office or agency maintained pursuant to Section
9.2 in a Place of Payment for that series, the Company shall execute, and the
Trustee


                                       36
<PAGE>   45
shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Registered Securities of the same series, of any
authorized denominations and of a like aggregate principal amount containing
identical terms and provisions.

                  Bearer Securities (except for any temporary global Bearer
Securities) or any coupons appertaining thereto (except for coupons attached to
any temporary global Bearer Security) shall be transferable by delivery.

                  At the option of the Holder, Registered Securities of any
series (except a Registered Security in global form) may be exchanged for other
Registered Securities of the same series, of any authorized denominations and of
a like aggregate principal amount containing identical terms and provisions,
upon surrender of the Registered Securities to be exchanged at such office or
agency. 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. Unless otherwise specified as contemplated by Section 3.1, Bearer
Securities may not be issued in exchange for Registered Securities.

                  Unless otherwise specified as contemplated by Section 3.1, at
the option of the Holder, Bearer Securities of such series may be exchanged for
Registered Securities (if the Securities of such series are issuable in
registered form) or Bearer Securities (if Bearer Securities of such series are
issuable in more than one denomination and such exchanges are permitted by such
series) of the same series, of any authorized denominations and of like tenor
and aggregate principal amount, upon surrender of the Bearer Securities to be
exchanged at any such office or agency, with all unmatured coupons and all
matured coupons in default thereto appertaining. If the Holder of a Bearer
Security is unable to produce any such unmatured coupon or coupons or matured
coupon or coupons in default, such


                                       37
<PAGE>   46
exchange may be effected if the Bearer Securities are accompanied by payment in
funds acceptable to the Company and the Trustee in an amount equal to the face
amount of such missing coupon or coupons, or the surrender of such missing
coupon or coupons may be waived by the Company 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 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 9.2, interest represented by coupons shall be payable only
upon presentation and surrender of those coupons at an office or agency located
outside the United States. Notwithstanding the foregoing, in case any Bearer
Security of any series is surrendered at any such office or agency in exchange
for a Registered Security of the same series 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, will not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security, but will be payable only
to the Holder of such coupon, when due in accordance with the provisions of this
Indenture.

                  Notwithstanding any other provision of this Section, unless
and until it is exchanged in whole or in part for Securities in certificated
form, a Security in


                                       38
<PAGE>   47
global form representing all or a portion of the Securities of a series may not
be transferred except as a whole by the Depositary for such series to a nominee
of such Depositary or by a nominee of such Depositary to such Depositary or
another nominee of such Depositary or by such Depositary or any such nominee to
a successor Depositary for such series or a nominee of such successor
Depositary.

                  If at any time the Depositary for the Securities of a series
notifies the Company that it is unwilling or unable to continue as Depositary
for the Securities of such series or if at any time the Depositary for the
Securities of such series shall no longer be eligible under Section 3.3, the
Company shall appoint a successor Depositary with respect to the Securities of
such series. If a successor Depositary for the Securities of such series is not
appointed by the Company within 90 days after the Company receives such notice
or becomes aware of such ineligibility, the Company's election pursuant to
Section 3.1(b)(23) shall no longer be effective with respect to the Securities
of such series and the Company shall execute, and the Trustee, upon receipt of a
Company Order for the authentication and delivery of certificated Securities of
such series of like tenor, shall authenticate and deliver, Securities of such
series of like tenor in certificated form, in authorized denominations and in an
aggregate principal amount equal to the principal amount of the Security or
Securities of such series of like tenor in global form in exchange for such
Security or Securities in global form.

                  The Company may at any time in its sole discretion determine
that Securities issued in global form shall no longer be represented by such a
Security or Securities in global form. In such event the Company shall execute,
and the Trustee, upon receipt of a Company Order for the authentication and
delivery of certificated Securities of such series of like tenor, shall
authenticate and deliver, Securities of such series of like tenor in
certificated form, in authorized denominations and in an aggregate


                                       39
<PAGE>   48
principal amount equal to the principal amount of the Security or Securities of
such series of like tenor in global form in exchange for such Security or
Securities in global form.

                  If specified by the Company pursuant to Section 3.1 with
respect to a series of Securities, the Depositary for such series may surrender
a Security in global form of such series in exchange in whole or in part for
Securities of such series in certificated form on such terms as are acceptable
to the Company and such Depositary. Thereupon, the Company shall execute, and
the Trustee shall authenticate and deliver, without service charge,

                  (i) to each Person specified by such Depositary a new
         certificated Security or Securities of the same series of like tenor,
         of any authorized denomination as requested by such Person in aggregate
         principal amount equal to and in exchange for such Person's beneficial
         interest in the Security in global form; and

                  (ii) to such Depositary a new Security in global form of like
         tenor in a denomination equal to the difference, if any, between the
         principal amount of the surrendered Security in global form and the
         aggregate principal amount of certificated Securities delivered to
         Holders thereof.

                  Upon the exchange of a Security in global form for Securities
in certificated form, such Security in global form shall be cancelled by the
Trustee. Unless expressly provided with respect to the Securities of any series
that such Security may be exchanged for Bearer Securities, Securities in
certificated form issued in exchange for a Security in global form pursuant to
this Section shall be registered in such names and in such authorized
denominations as the Depositary for such Security in global form, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. The


                                       40
<PAGE>   49
Trustee shall deliver such Securities to the Persons in whose names such
Securities are so registered.

                  Whenever any Securities are surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the
Securities which the Holder making the exchange is entitled to receive.

                  All Securities issued upon any registration of transfer or
upon any exchange of Securities shall be the valid obligations of the Company,
evidencing the same debt, and entitled to the same benefits under this
Indenture, as the Securities surrendered upon such registration of transfer or
exchange.

                  Every Registered Security presented or surrendered for
registration of transfer or for exchange shall (if so required by the Company,
the Registrar or the Trustee) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Company, the Registrar and
the Trustee 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 for any exchange of Securities, but the Company may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any registration or transfer or exchange of
Securities, other than exchanges pursuant to Section 3.4 or 10.7 not involving
any transfer.

                  The Company shall not be required (i) to issue, register the
transfer of, or exchange any Securities for a period beginning at the opening of
business 15 days before any selection for redemption of Securities of like tenor
and of the series of which such Security is a part and ending at the close of
business on the earliest date on which the relevant notice of redemption is
deemed to have been given to all Holders of Securities of like tenor and of such
series to be redeemed; (ii) to register the transfer of or


                                       41
<PAGE>   50
exchange any Registered Security so selected for redemption, in whole or in
part, except the unredeemed portion of any Security being redeemed in part; or
(iii) to exchange any Bearer Security so selected for redemption, except that
such a Bearer Security may be exchanged for a Registered Security of that series
and like tenor; provided that such Registered Security shall be simultaneously
surrendered for redemption.

                  Section 3.6. Replacement Securities. If a mutilated Security
or a Security with a mutilated coupon appertaining to it is surrendered to the
Trustee, together with, in proper cases, such security or indemnity as may be
required by the Company or the Trustee to save each of them harmless, the
Company shall execute and the Trustee shall authenticate and deliver a
replacement Registered Security, if such surrendered Security was a Registered
Security, or a replacement Bearer Security with coupons corresponding to the
coupons appertaining to the surrendered Security, if such surrendered Security
was a Bearer Security, of the same series and date of maturity, if the Trustee's
requirements are met.

                  If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
or Security with a destroyed, lost or stolen 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 or the
Trustee that such Security or coupon has been acquired by a bona fide purchaser,
the Company shall execute and the Trustee shall authenticate and deliver in lieu
of any such destroyed, lost or stolen Security or in exchange for the Security
to which a destroyed, lost or stolen coupon appertains (with all appurtenant
coupons not destroyed, lost or stolen), a replacement Registered Security, if
such Holder's claim appertains to a Registered Security, or a replacement Bearer
Security with coupons corresponding to the coupons appertaining to the
destroyed, lost or stolen Bearer Security or the Bearer Security to which such
lost, destroyed or stolen


                                       42
<PAGE>   51
coupon appertains, if such Holder's claim appertains to a Bearer Security, of
the same series and principal amount, containing identical terms and provisions
and bearing a number not contemporaneously outstanding with coupons
corresponding to the coupons, if any, appertaining to the destroyed, lost or
stolen Security.

                  In case any such mutilated, destroyed, lost or stolen Security
or coupon has become or is about to become due and payable, the Company in its
discretion may, instead of issuing a new Security or coupon, pay such Security
or coupon; provided, however, that payment of principal of and any premium or
interest on Bearer Securities shall, except as otherwise provided in Section
9.2, be payable only at an office or agency located outside the United States
and, unless otherwise specified as contemplated by Section 3.1, any interest on
Bearer Securities 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 of any series with its coupons, if any,
issued pursuant to this Section in lieu of any destroyed, lost or stolen
Security, or in exchange for a Security to which a destroyed, lost or stolen
coupon appertains, shall constitute an original additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Security
and its coupon, if any, 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 that
securities and their coupons, if any, duly issued hereunder.


                                       43
<PAGE>   52
                  The provisions of this Section are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Securities or
coupons.

                  Section 3.7. Payment of Interest; Interest Rights Preserved.
(a) Unless otherwise provided as contemplated by Section 3.1, interest, if any,
on any Registered Security which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest at the office or
agency maintained for such purpose pursuant to 9.2; provided, however, that at
the option of the Company, interest on any series of Registered Securities that
bear interest may be paid (i) by check mailed to the address of the Person
entitled thereto as it shall appear on the Register of Holders of Securities of
such series or (ii) at the expense of the Company, by wire transfer to an
account maintained by the Person entitled thereto as specified in the Register
of Holders of Securities of such series.

                  Unless otherwise provided as contemplated by Section 3.1, (i)
interest, if any, on Bearer Securities shall be paid only against presentation
and surrender of the coupons for such interest installments as are evidenced
thereby as they mature and (ii) original issue discount, if any, on Bearer
Securities shall be paid only against presentation and surrender of such
Securities; in either case at the office of a Paying Agent located outside the
United States, unless the Company shall have otherwise instructed the Trustee in
writing provided that any such instruction for payment in the United States does
not cause any Bearer Security to be treated as a "registration-required
obligation" under United States laws and regulations. The interest, if any, on
any temporary Bearer Security shall be paid, as to any installment of interest
evidenced by a coupon attached thereto only upon presentation and surrender of
such coupon and, as to other installments of interest,


                                       44
<PAGE>   53
only upon presentation of such Security for notation thereon of the payment of
such interest. If at the time a payment of principal of or interest, if any, on
a Bearer Security or coupon shall become due, the payment of the full amount so
payable at the office or offices of all the Paying Agents outside the United
States is illegal or effectively precluded because of the imposition of
exchange controls or other similar restrictions on the payment of such amount in
Dollars, then the Company may instruct the Trustee in writing to make such
payments at a Paying Agent located in the United States, provided that provision
for such payment in the United States would not cause such Bearer Security to be
treated as a "registration-required obligation" under United States laws and
regulations.

                  (b) Unless otherwise provided as contemplated by Section 3.1,
any interest on Registered Securities of any series which is payable, but is not
punctually paid or duly provided for, on any interest payment date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holders
on the relevant Regular Record Date by virtue of their having been such Holders,
and such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below:

                  (1) The Company may elect to make payment of such Defaulted
         Interest to the Persons in whose names such Registered Securities (or
         their respective Predecessor Securities) are registered at the close of
         business on a Special Record Date for the payment of such Defaulted
         Interest, which shall be fixed in the following manner. The Company
         shall deposit with the Trustee an amount of money equal to the
         aggregate amount proposed to be paid in respect of such Defaulted
         Interest or shall make arrangements satisfactory to the trustee for
         such deposit prior to the date of the proposed payment, such money when
         deposited to be held in trust for the benefit of the Persons entitled
         to such Defaulted Interest as in this clause (1) provided. Thereupon
         the Trustee shall fix a Special Record Date for the payment


                                       45
<PAGE>   54
         of such Defaulted Interest which shall be not more than 15 days and not
         less than 10 days prior to the date of the proposed payment and not
         less than 10 days after the receipt by the Trustee of the notice of the
         proposed payment. The Trustee shall promptly notify the Company of such
         Special Record Date and, in the name and at the expense of the Company,
         shall cause notice of the proposed payment of such Defaulted Interest
         and the Special Record Date therefor to be mailed, first-class postage
         prepaid, to each Holder of such Registered Securities at his address as
         it appears in the Register, not less than 10 days prior to such Special
         Record Date. Notice of the proposed payment of such Defaulted Interest
         and the Special Record Date therefor having been so mailed, such
         Defaulted Interest shall be paid to the Persons in whose names such
         Registered Securities (or their respective Predecessor Securities) are
         registered at the close of business on such Special Record Date and
         shall no longer be payable pursuant to the following clause (2).

                  (2) The Company may make payment of such Defaulted Interest
         to the Persons in whose names such Registered Securities (or their
         respective Predecessor Securities) are registered at the close of
         business on a specified date in any other lawful manner not
         inconsistent with the requirements of any securities exchange on which
         such Registered Securities may be listed, and upon such notice as may
         be required by such exchange, if, after notice given by the Company to
         the Trustee of the proposed payment pursuant to this clause (2), such
         manner of payment shall be deemed practicable by the Trustee.

                  (c) Subject to the foregoing provisions of this Section and
Section 3.5, 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 3.8. Persons Deemed Owners. Prior to due presentment
of any Registered Security for registration of transfer, the Company, the
Trustee and any agent of the Company or the Trustee may treat the Person in
whose name such Registered Security is registered as the owner of such
Registered Security for the purpose of receiving payment of principal of,
premium, if any, and (subject to Section 3.7) interest on such Registered
Security and for all other purposes whatsoever, whether or not such Registered
Security be overdue, and neither the Company, the Trustee nor any agent of the
Company or the Trustee shall be affected by notice to the contrary.

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

                  None of the Company, the Trustee or any agent of the Company
or the Trustee shall have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Security in global form, or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.
Notwithstanding the foregoing, with respect to any Security in global form,
nothing herein shall prevent the Company or the Trustee, or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by any Depositary (or its nominee), as a
Holder, with respect to such Security in global form or impair, as between such
Depositary and owners of beneficial interests in such Security in global form,
the operation of customary practices governing the exercise of the rights of
such


                                       47
<PAGE>   56
Depositary (or its nominee) as Holder of such Security in global form.

                  Section 3.9. Cancellation. The Company at any time may deliver
Securities and coupons to the Trustee for cancellation. The Registrar and any
Paying Agent shall forward to the Trustee any Securities and coupons surrendered
to them for replacement, for registration of transfer, or for exchange or
payment. The Trustee shall cancel all Securities and coupons surrendered for
replacement, for registration of transfer, or for exchange, payment, redemption
or cancellation and shall dispose of cancelled Securities and coupons and, at
the request of the Company, shall issue a certificate of destruction to the
Company. The Company may not issue new Securities to replace Securities that it
has paid or delivered to the Trustee for cancellation.

                  Section 3.10. Computation of Interest. Except as otherwise
specified as contemplated by Section 3.1, interest on the Securities of each
series shall be computed on the basis of a 360-day year of twelve 30-day months.

                  Section 3.11. CUSIP Numbers. The Company in issuing the
Securities may use "CUSIP" numbers (if then generally in use), and, in such
case, the Trustee shall use "CUSIP" numbers in notices of redemption as a
convenience to Holders; provided that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such numbers.

                  Section 3.12. Currency and Manner of Payment in Respect of
Securities. (a) Unless otherwise specified with respect to any Securities
pursuant to Section 3.1, with respect to Registered Securities of any series not
permitting the election provided for in paragraph (b) below


                                       48
<PAGE>   57
or the Holders of which have not made the election provided for in paragraph (b)
below, and with respect to Bearer Securities of any series, except as provided
in paragraph (d) below, payment of the principal of, premium, if any, and
interest, if any, on any Registered or Bearer Security of such series will be
made in the currency or currencies or currency unit or units in which such
Registered Security or Bearer Security, as the case may be, is payable. The
provisions of this Section 3.12 may be modified or superseded pursuant to
Section 3.1 with respect to any Securities.

                  (b) It may be provided pursuant to Section 3.1, with respect
to Registered Securities of any series, that Holders shall have the option,
subject to paragraphs (d) and (e) below, to receive payments of principal of,
premium, if any, or interest, if any, on such Registered Securities in any of
the currencies or currency units which may be designated for such election by
delivering to the Trustee (or the applicable Paying Agent) a written election
with signature guarantees and in the applicable form established pursuant to
Section 3.1, not later than the close of business on the Election Date
immediately preceding the applicable payment date. If a Holder so elects to
receive such payments in any such currency or currency unit, such election will
remain in effect for such Holder or any transferee of such Holder until changed
by such Holder or such transferee by written notice to the Trustee (or any
applicable Paying Agent) for such series of Registered Securities (but any such
change must be made not later than the close of business on the Election Date
immediately preceding the next payment date to be effective for the payment to
be made on such payment date, and no such change of election may be made with
respect to payments to be made on any Registered Security of such series with
respect to which an Event of Default has occurred or with respect to which the
Company has deposited funds pursuant to Article 4 or with respect to which a
notice of redemption has been given by the Company). Any Holder of any such
Registered Security who shall not have delivered any such election to


                                       49
<PAGE>   58
the Trustee (or any applicable Paying Agent) not later than the close of
business on the applicable Election Date will be paid the amount due on the
applicable payment date in the relevant currency or currency unit as provided in
Section 3.12(a). The Trustee (or the applicable Paying Agent) shall notify the
Exchange Rate Agent as soon as practicable after the Election Date of the
aggregate principal amount of Registered Securities for which Holders have made
such written election.

                  (c) If the election referred to in paragraph (b) above has
been provided for with respect to any Registered Securities of a series pursuant
to Section 3.1, then, unless otherwise specified pursuant to Section 3.1 with
respect to any such Registered Securities, not later than the fourth Business
Day after the Election Date for each payment date for such Registered
Securities, the Exchange Rate Agent will deliver to the Company a written notice
specifying, in the currency or currencies or currency unit or units in which
Registered Securities of such series are payable, the respective aggregate
amounts of principal of, premium, if any, and interest, if any, on such
Registered Securities to be paid on such payment date, and specifying the
amounts in such currency or currencies or currency unit or units so payable in
respect of such Registered Securities as to which the Holders of Registered
Securities denominated in any currency or currencies or currency unit or units
shall have elected to be paid in another currency or currency unit as provided
in paragraph (b) above. If the election referred to in paragraph (b) above has
been provided for with respect to any Registered Securities of a series pursuant
to Section 3.1, and if at least one Holder has made such election, then, unless
otherwise specified pursuant to Section 3.1, on the second Business Day
preceding such payment date the Company will deliver to the Trustee (or the
applicable Paying Agent) an Exchange Rate Officers' Certificate in respect of
the Dollar, Foreign Currency or Currencies, ECU or other currency unit payments
to be made on such payment date. Unless otherwise specified pursuant to Section
3.1, the Dollar, Foreign Currency or Currencies, ECU or other


                                       50
<PAGE>   59
currency unit amount receivable by Holders of Registered Securities who have
elected payment in a currency or currency unit as provided in paragraph (b)
above shall be determined by the Company on the basis of the applicable Market
Exchange Rate in effect on the second Business Day (the "Valuation Date")
immediately preceding each payment date, and such determination shall be
conclusive and binding for all purposes, absent manifest error.

                  (d) If a Conversion Event occurs with respect to a Foreign
Currency, ECU or any other currency unit in which any of the Securities are
denominated or payable otherwise than pursuant to an election provided for
pursuant to paragraph (b) above, then, with respect to each date for the
payment of principal of, premium, if any, and interest, if any, on the
applicable Securities denominated or payable in such Foreign Currency, ECU or
such other currency unit occurring after the last date on which such Foreign
Currency, ECU or such other currency unit was used (the "Conversion Date"), the
Dollar shall be the currency of payment for use on each such payment date (but
such Foreign Currency, ECU or such other currency unit that was previously the
currency of payment shall, at the Company's election, resume being the currency
of payment on the first such payment date preceded by 15 Business Days during
which the circumstances which gave rise to the Dollar becoming such currency no
longer prevail). Unless otherwise specified pursuant to Section 3.1, the Dollar
amount to be paid by the Company to the Trustee or any applicable Paying Agent
and by the Trustee or any applicable Paying Agent to the Holders of such
Securities with respect to such payment date shall be, in the case of a Foreign
Currency other than a currency unit, the Dollar Equivalent of the Foreign
Currency or, in the case of a Foreign Currency that is a currency unit, the
Dollar Equivalent of the Currency Unit, in each case as determined by the
Exchange Rate Agent in the manner provided in paragraph (f) or (g) below.

                  (e) Unless otherwise specified pursuant to Section 3.1, if
the Holder of a Registered Security denominated


                                       51
<PAGE>   60
in any currency or currency unit shall have elected to be paid in another
currency or currency unit or in other currencies as provided in paragraph (b)
above, and (i) a Conversion Event occurs with respect to any such elected
currency or currency unit, such Holder shall receive payment in the currency or
currency unit in which payment would have been made in the absence of such
election and (ii) if a Conversion Event occurs with respect to the currency or
currency unit in which payment would have been made in the absence of such
election, such Holder shall receive payment in Dollars as provided in paragraph
(d) of this Section 3.12 (but, subject to any contravening valid election
pursuant to paragraph (b) above, the elected payment currency or currency unit,
in the case of the circumstances described in clause (i) above, or the payment
currency or currency unit in the absence of such election, in the case of the
circumstances described in clause (ii) above, shall, at the Company's election,
resume being the currency or currency unit of payment with respect to Holders
who have so elected, but only with respect to payments on payment dates preceded
by 15 Business Days during which the circumstances which gave rise to such
currency or currency unit, in the case of the circumstances described in clause
(i) above, or the Dollar, in the case of the circumstances described in clause
(ii) above, as applicable, becoming the currency or currency unit of payment, no
longer prevail).

                  (f) The "Dollar Equivalent of the Foreign Currency" shall be
determined by the Exchange Rate Agent and shall be obtained for each subsequent
payment date by the Exchange Rate Agent by converting the specified Foreign
Currency into Dollars at the Market Exchange Rate on the Conversion Date.

                  (g) The "Dollar Equivalent of the Currency Unit" shall be
determined by the Exchange Rate Agent and, subject to the provisions of
paragraph (h) below, shall be the sum of each amount obtained by converting the
Specified Amount of each Component Currency (as each such term is defined in
paragraph (h) below) into Dollars at the Market Exchange


                                       52
<PAGE>   61
Rate for such Component Currency on the Valuation Date with respect to each
payment.

                  (h) For purposes of this Section 3.12 the following terms
shall have the following meanings:

                  A "Component Currency" shall mean any currency which, on the
Conversion Date, was a component currency of the relevant currency unit,
including, but not limited to, ECU.

                  "Election Date" shall mean the Regular Record Date for the
applicable series of Registered Securities as specified pursuant to Section 3.1
by which the written election referred to in Section 3.12(b) may be made.

                  A "Specified Amount" of a Component Currency shall mean the
number of units of such Component Currency or fractions thereof which such
Component Currency represented in the relevant currency unit, including, but not
limited to, ECU, on the Conversion Date. If after the Conversion Date the
official unit of any Component Currency is altered by way of combination or
subdivision, the Specified Amount of such Component Currency shall be divided or
multiplied in the same proportion. If after the Conversion Date two or more
Component Currencies are consolidated into a single currency, the respective
Specified Amounts of such Component Currencies shall be replaced by an amount in
such single currency equal to the sum of the respective Specified Amounts of
such consolidated Component Currencies expressed in such single currency, and
such amount shall thereafter be a Specified Amount and such single currency
shall thereafter be a Component Currency. If after the Conversion Date any
Component Currency shall be divided into two or more currencies, the Specified
Amount of such Component Currency shall be replaced by specified amounts of such
two or more currencies, the sum of which, at the Market Exchange Rate of such
two or more currencies on the date of such replacement, shall be equal to the
Specified Amount of such former Component Currency and such amounts shall
thereafter be


                                       53
<PAGE>   62
Specified Amounts and such currencies shall thereafter be Component Currencies.
If, after the Conversion Date of the relevant currency unit, including, but not
limited to, ECU, a Conversion Event (other than any event referred to above in
this definition of "Specified Amount") occurs with respect to any Component
Currency of such currency unit and is continuing on the applicable Valuation
Date, the Specified Amount of such Component Currency shall, for purposes of
calculating the Dollar Equivalent of the Currency Unit, be converted into
Dollars at the Market Exchange Rate in effect on the Conversion Date of such
Component Currency.

                  All decisions and determinations of the Exchange Rate Agent
regarding the Dollar Equivalent of the Foreign Currency, the Dollar Equivalent
of the Currency Unit, the Market Exchange Rate and changes in the Specified
Amounts as specified above shall be in its sole discretion and shall, in the
absence of manifest error, be conclusive for all purposes and irrevocably
binding upon the Company, the Trustee (and any applicable Paying Agent) and all
Holders of Securities denominated or payable in the relevant currency,
currencies or currency units. The Exchange Rate Agent shall promptly give
written notice to the Company and the Trustee of any such decision or
determination.

                  In the event that the Company determines in good faith that a
Conversion Event has occurred with respect to a Foreign Currency, the Company
will promptly give written notice thereof to the Trustee (or any applicable
Paying Agent) and to the Exchange Rate Agent (and the Trustee (or such Paying
Agent) will promptly thereafter give notice in the manner provided in Section
1.6 to the affected Holders) specifying the Conversion Date. In the event the
Company so determines that a Conversion Event has occurred with respect to ECU
or any other currency unit in which Securities are denominated or payable, the
Company will promptly give written notice thereof to the Trustee (or any
applicable Paying Agent) and to the Exchange Rate Agent (and the Trustee (or
such Paying Agent)) will promptly thereafter


                                       54
<PAGE>   63
give notice in the manner provided in Section 1.6 to the affected Holders)
specifying the Conversion Date and the Specified Amount of each Component
Currency on the Conversion Date. In the event the Company determines in good
faith that any subsequent change in any Component Currency as set forth in the
definition of Specified Amount above has occurred, the Company will similarly
give written notice to the Trustee (or any applicable Paying Agent) and to the
Exchange Rate Agent.

                  The Trustee of the appropriate series of Securities shall be
fully justified and protected in relying and acting upon information received by
it from the Company and the Exchange Rate Agent and shall not otherwise have any
duty or obligation to determine the accuracy or validity of such information
independent of the Company or the Exchange Rate Agent.

                  Section 3.13. Appointment and Resignation of Exchange Rate
Agent. (a) Unless otherwise specified pursuant to Section 3.1, if and so long as
the Securities of any series (i) are denominated in a currency other than
Dollars or (ii) may be payable in a currency other than Dollars, 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. The Company will cause the Exchange Rate Agent
to make the necessary foreign exchange determinations at the time and in the
manner specified pursuant to Section 3.12 for the purpose of determining the
applicable rate of exchange and, if applicable, for the purpose of converting
the issued currency or currencies or currency unit or units into the applicable
payment currency or currency unit for the payment of principal, premium, if any,
and interest, if any, pursuant to Section 3.12.

                  (b) No resignation of the Exchange Rate Agent and no
appointment of a successor Exchange Rate Agent pursuant to this Section shall
become effective until the acceptance


                                       55
<PAGE>   64
of appointment by the successor Exchange Rate Agent as evidenced by a written
instrument delivered to the Company and the Trustee of the appropriate series of
Securities accepting such appointment executed by the successor Exchange Rate
Agent.

                  (c) If the Exchange Rate Agent shall resign, be removed or
become incapable of acting, or if a vacancy shall occur in the office of the
Exchange Rate Agency 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 Exchange Rate Agent or Exchange Rate Agents with respect to
the Securities of that or those series (it being understood that any such
successor Exchange Rate Agent may be appointed with respect to the Securities of
one or more or all of such series and that, unless otherwise specified pursuant
to Section 3.1, at any time there shall only be one Exchange Rate Agent with
respect to the Securities of any particular series that are originally issued by
the Company on the same date and that are initially denominated and/or payable
in the same currency or currencies or currency unit or units).

                     Satisfaction, Discharge and Defeasance

                  Section 4.1. Termination of Company's Obligations Under the
Indenture. (a) This Indenture shall upon a Company Request cease to be of
further effect with respect to Securities of or within any series and any
coupons appertaining thereto (except as to any surviving rights of registration
of transfer or exchange of such Securities and replacement of such Securities
which may have been lost, stolen or mutilated as herein expressly provided for)
and the Trustee, at the expense of the Company, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture with respect to such
Securities and any coupons appertaining thereto when

                  such coupons appertaining to Bearer Securities surrendered in
                  exchange for Registered Securities and maturing after such
                  exchange, surrender of which is not required or has been

                  coupons which have been destroyed, lost or stolen and which
                  have been replaced or paid as provided in Section 3.6, (iii)

                  has theretofore been deposited in trust or segregated and held

                  or discharged from such trust, as provided in Section 9.3)
                  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

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


                                       57
<PAGE>   66
         and the Company, in the case of (i), (ii) or (iii) above, has
         irrevocably deposited or caused to be deposited with the Trustee as
         trust funds in trust for the purpose an amount in the currency or
         currencies or currency unit or units in which the Securities of such
         series are payable, sufficient to pay and discharge the entire
         indebtedness on such Securities and such coupons not theretofore
         delivered to the Trustee for cancellation, for principal, premium, if
         any, and interest, with respect thereto, to the date of such deposit
         (in the case of Securities which have become due and payable) or to the
         Stated Maturity or Redemption Date, as the case may be;

                  (2)  the Company has paid or caused to be paid all
         other sums payable hereunder by the Company; and

                  (3) the Company 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.

Notwithstanding the satisfaction and discharge of this Indenture, the obligation
of the Company to the Trustee and any predecessor Trustee under Section 6.9, the
obligations of the Company to any Authenticating Agent under Section 6.14 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 under Section 4.2 and
the last paragraph of Section 9.3 shall survive.

                  Section 4.2. Application of Trust Funds. Subject to the
provisions of the last paragraph of Section 9.3, all money deposited with the
Trustee pursuant to Section 4.1 shall be held in trust and applied by it, in
accordance with the provisions of the Securities, the coupons and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled


                                       58
<PAGE>   67
thereto, of the principal, premium, if any and any interest for whose payment
such money has been deposited with or received by the Trustee, but such money
need not be segregated from other funds except to the extent required by law.

                  Section 4.3. Applicability of Defeasance Provisions;
Company's Option to Effect Defeasance or Covenant Defeasance. If pursuant to
Section 3.1 provision is made for either or both of (i) defeasance of the
Securities of or within a series under Section 4.4 or (ii) covenant defeasance
of the Securities of or within a series under Section 4.5, then the provisions
of such Section or Sections, as the case may be, together with the provisions
of Sections 4.6 through 4.9 inclusive, with such modifications thereto as may be
specified pursuant to Section 3.1 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, at any time, with respect to such
Securities and any coupons appertaining thereto, elect to have Section 4.4 (if
applicable) or Section 4.5 (if applicable) be applied to such Outstanding
Securities and any coupons appertaining thereto upon compliance with the
conditions set forth below in this Article.

                  Section 4.4. Defeasance and Discharge. Upon the Company's
exercise of the option specified in Section 4.3 applicable to this Section with
respect to the Securities of or within a series, the Company shall be deemed to
have been discharged from its obligations with respect to such Securities and
any coupons appertaining thereto on the date the conditions set forth in Section
4.6 are satisfied (hereinafter "defeasance"). For this purpose, such defeasance
means that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by such Securities and any coupons appertaining thereto
which shall thereafter be deemed to be "Outstanding" only for the purposes of
Section 4.7 and the other Sections of this Indenture referred to in clause (ii)
of this Section, and to


                                       59
<PAGE>   68
have satisfied all 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 on a Company Order execute proper instruments acknowledging
the same), except the following which shall survive until otherwise terminated
or discharged hereunder: (i) the rights of Holders of such Securities and any
coupons appertaining thereto to receive, solely from the trust funds described
in Section 4.6(a) and as more fully set forth in such Section, payments in
respect of the principal of, premium, if any, and interest, if any, on such
Securities or any coupons appertaining thereto when such payments are due; (ii)
the Company's obligations with respect to such Securities under Sections 3.5,
3.6, 9.2 and 9.3 and with respect to the payment of additional amounts, if any,
payable with respect to such Securities as specified pursuant to Section
3.1(b)(16); (iii) the rights, powers, trusts, duties and immunities of the
Trustee hereunder and (iv) this Article 4. Subject to compliance with this
Article 4, the Company may exercise its option under this Section
notwithstanding the prior exercise of its option under Section 4.5 with respect
to such Securities and any coupons appertaining thereto. Following a defeasance,
payment of such Securities may not be accelerated because of an Event of
Default.

                  Section 4.5. Covenant Defeasance. Upon the Company's exercise
of the option specified in Section 4.3 applicable to this Section with respect
to any Securities of or within a series, the Company shall be released from its
obligations under Sections 7.1, 9.4, 9.5, 9.9 and 9.10 and, if specified
pursuant to Section 3.1, its obligations under any other covenant, with respect
to such Securities and any coupons appertaining thereto on and after the date
the conditions set forth in Section 4.6 are satisfied (here inafter, "covenant
defeasance"), and such Securities and any coupons appertaining thereto shall
thereafter be deemed to be not "Outstanding" for the purposes of any direction,
waiver, consent or declaration or Act of Holders (and the


                                       60
<PAGE>   69
consequences of any thereof) in connection with Sections 7.1, 9.4, 9.5, 9.9 and
9.10 or such other 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 Securities and any coupons appertaining thereto, the
Company 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 5.1(3) or 5.1(7) or otherwise, as the case may
be, but, except as specified above, the remainder of this Indenture and such
Securities and any coupons appertaining thereto shall be unaffected thereby.

                  Section 4.6. Conditions to Defeasance or Covenant Defeasance.
The following shall be the conditions to application of Section 4.4 or Section
4.5 to any Securities of or within a series and any coupons appertaining
thereto:

                  (a) The Company shall have deposited or caused to be deposited
         irrevocably with the Trustee (or another trustee satisfying the
         requirements of Section 6.12 who shall agree to comply with, and shall
         be entitled to the benefits of, the provisions of Sections 4.3 through
         4.9 inclusive and the last paragraph of Section 9.3 applicable to the
         Trustee, for purposes of such Sections also a "Trustee") as trust funds
         in trust for the purpose of making the payments referred to in clauses
         (x) and (y) of this Section 4.6(a), specifically pledged as security
         for, and dedicated solely to, the benefit of the Holders of such
         Securities and any coupons appertaining thereto, with instructions to
         the Trustee as to the application thereof, (A) money in an amount (in
         such currency, currencies or currency unit or units in which such


                                       61
<PAGE>   70
         Securities and any coupons appertaining thereto are then specified as
         payable at Maturity), or (B) if Securities of such series are not
         subject to repayment at the option of Holders, Government Obligations
         which through the payment of interest and principal in respect thereof
         in accordance with their terms will provide, not later than one day
         before the due date of any payment referred to in clause (x) or (y) of
         this Section 4.6(a), money in an amount or (C) a combination thereof in
         an amount, sufficient, in the opinion of a nationally recognized firm
         of independent certified public accountants expressed in a written
         certification thereof delivered to the Trustee, to pay and discharge,
         and which shall be applied by the Trustee to pay and discharge, (x) the
         principal of, premium, if any, and interest, if any, on such Securities
         and any coupons appertaining thereto on the Maturity of such principal
         or installment of principal or interest and (y) any mandatory sinking
         fund payments applicable to such Securities on the day on which such
         payments are due and payable in accordance with the terms of this
         Indenture and such Securities and any coupons appertaining thereto.
         Before such a deposit the Company may make arrangements satisfactory to
         the Trustee for the redemption of Securities at a future date or dates
         in accordance with Article 10 which shall be given effect in applying
         the foregoing.

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

                  (c) In the case of an election under Section 4.4, the Company
         shall have delivered to the Trustee an Officers' Certificate and an
         Opinion of Counsel to the effect that (i) the Company has received
         from, or there


                                       62
<PAGE>   71
         has been published by, the Internal Revenue Service a 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 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
         amount and in the same manner and at the same times, as would have been
         the case if such deposit, defeasance and discharge had not occurred.

             (d) In the case of an election under Section 4.5, the Company shall
         have delivered to the Trustee an Opinion of Counsel to the effect that
         the Holders of such 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.

             (e) The Company shall have delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent to the defeasance under Section 4.4 or the covenant
         defeasance under Section 4.5 (as the case may be) have been complied
         with.

                  (f) 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 in connection therewith
         as contemplated by Section 3.1.

                  Section 4.7. Deposited Money and Government Obligations to Be
Held in Trust. Subject to the provisions of the last paragraph of Section 9.3,
all money and


                                       63
<PAGE>   72
Government Obligations (or other property as may be provided pursuant to Section
3.1) (including the proceeds thereof) deposited with the Trustee pursuant to
Section 4.6 in respect of any 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, premium, if any, and interest, if any, but such money need not be
segregated from other funds except to the extent required by law.

                  Unless otherwise specified with respect to any Security
pursuant to Section 3.1, if, after a deposit referred to in Section 4.6(a) has
been made, (i) the Holder of a Security in respect of which such deposit was
made is entitled to, and does, elect pursuant to Section 3.12(b) or the terms of
such Security to receive payment in a currency or currency unit other than that
in which the deposit pursuant to Section 4.6(a) has been made in respect of such
Security, or (ii) a Conversion Event occurs as contemplated in Section 3.12(d)
or 3.12(e) or by the terms of any Security in respect of which the deposit
pursuant to Section 4.6(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,
premium, if any, and interest, if any, on 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 or currency unit in which such
Security becomes payable as a result of such election or Conversion Event based
on the applicable Market Exchange Rate for such currency or currency unit in
effect on the second Business Day prior to each payment date, except, with


                                       64
<PAGE>   73
respect to a Conversion Event, for such currency or currency unit in effect (as
nearly as feasible) at the time of the Conversion Event.

                  Section 4.8. Repayment to Company. The Trustee (and any Paying
Agent) shall promptly pay to the Company upon Company Request any excess money
or securities held by them at any time.

                  Section 4.9. Indemnity for Government Obligations. The
Company shall pay, and shall indemnify the Trustee against, any tax, fee or
other charge imposed on or assessed against Government Obligations deposited
pursuant to this Article or the principal and interest received on such
Government Obligations.

                              Defaults and Remedies

                  Section 5.1. Events of Default. An "Event of Default" occurs
with respect to the Securities of any series if (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):

                  (1) the Company defaults in the payment of interest on any
         Security of that series or any coupon appertaining thereto or any
         additional amount payable with respect to any Security of that series
         as specified pursuant to Section 3.1(b)(16) when the same becomes due
         and payable and such default continues for a period of 30 days;

                  (2) the Company defaults in the payment of the principal of or
         any premium on any Security of that series when the same becomes due
         and payable at its

<PAGE>   74
         Maturity or on redemption or otherwise, or in the payment of a
         mandatory sinking fund payment when and as due by the terms of the
         Securities of that series;

                  (3) the Company fails to comply in any material respect with
         any of its agreements or covenants in, or any of the provisions of,
         this Indenture with respect to any Security of that series (other than
         an agreement, covenant or provision for which non-compliance is
         elsewhere in this Section specifically dealt with), and such
         non-compliance continues for a period of 60 days after there has been
         given, by registered or certified mail, to the Company by the Trustee
         or to the Company and the Trustee by the Holders of at least 25% in
         principal amount of the Outstanding Securities of the series, a written
         notice specifying such default or breach and requiring it to be
         remedied and stating that such notice is a "Notice of Default"
         hereunder;

                  (4) the Company pursuant to or within the meaning of any
         Bankruptcy Law (A) commences a voluntary case, (B) consents to the
         entry of an order for relief against it in an involuntary case, (C)
         consents to the appointment of a Custodian of it or for all or
         substantially all of its property; or (D) makes a general assignment
         for the benefit of its creditors;

                  (5) a court of competent jurisdiction enters an order or
         decree under any Bankruptcy Law that (A) is for relief against the
         Company in an involuntary case, (B) appoints a Custodian of the Company
         or for all or substantially all of its property, or (C) orders the
         liquidation of the Company and the order or decree remains unstayed and
         in effect for 60 days; or

                  (6) any other Event of Default provided as contemplated by
         Section 3.1 with respect to Securities of that series.


                                       66
<PAGE>   75
                  The term "Bankruptcy Law" means Title 11, U.S. Code, or any
similar federal or state law for the relief of debtors. The term "Custodian"
means any receiver, trustee, assignee, liquidator or similar official under any
Bankruptcy Law.

                  Section 5.2. Acceleration; Rescission and Annulment. If an
Event of Default with respect to the Securities of any series at the time
Outstanding occurs and is continuing, the Trustee or the Holders of at least 25%
in aggregate principal amount of all of the Outstanding Securities of that
series, by written notice to the Company (and, if given by the Holders, to the
Trustee), may declare the principal (or, if the Securities of that series are
Original Issue Discount Securities or Indexed Securities, such portion of the
principal amount as may be specified in the terms of that series) of and accrued
interest, if any, on all the Securities of that series to be due and payable and
upon any such declaration such principal (or, in the case of Original Issue
Discount Securities or Indexed Securities, such specified amount) and interest,
if any, shall be immediately due and payable.

                  At any time after such a declaration of acceleration with
respect to Securities of any series has been made and before a judgement or
decree for payment of the money due has been obtained by the Trustee as
hereinafter in this Article provided, the Holders of a majority in aggregate
principal amount of the Outstanding Securities of that series, by written notice
to the Trustee, may rescind and annul such declaration and its consequences if
all existing Defaults and Events of Default with respect to Securities of that
series, other than the non-payment of the principal of Securities of that series
which have become due solely by such declaration of acceleration, have been
cured or waived as provided in Section 5.7. No such rescission shall affect any
subsequent default or impair any right consequent thereon.


                                       67
<PAGE>   76
                  Section 5.3. Collection of Indebtedness and Suits for
Enforcement by Trustee. The Company covenants that if

                  (1) default is made in the payment of any interest on any
         Security or coupon, if any, when such interest becomes due and payable
         and such default continues for a period of 30 days, or

                  (2) default is made in the payment of the principal of (or
         premium, if any, on) any Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities or coupons, if any, the whole amount then due and
payable on such Securities for principal, premium, if any, and interest and, to
the extent that payment of such interest shall be legally enforceable, interest
on any overdue principal, premium, if any, and on any overdue interest, at the
rate or rates prescribed therefor in such Securities or coupons, if any, and, in
addition thereto, such further amount as shall be sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

                  If 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 by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to secure any other proper remedy.

                  Section 5.4. Trustee May File Proofs of Claim. The Trustee may
file such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Holders of
Securities


                                       68
<PAGE>   77
allowed in any judicial proceedings relating to the Company, its creditors or
its property.

                  Section 5.5. Trustee May Enforce Claims Without Possession of
Securities. All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto.

                  Section 5.6. Delay or Omission Not Waiver. No delay or
omission by the Trustee or any Holder of any Securities to exercise any right or
remedy accruing upon an Event of Default shall impair any such right or remedy
or constitute a waiver of or acquiescence in any such Event of Default.

                  Section 5.7. Waiver of Past Defaults. The Holders of a
majority in aggregate principal amount of Outstanding Securities of any series
by written notice to the Trustee may waive on behalf of the Holders of all
Securities of such series a past Default or Event of Default with respect to
that series and its consequences except (i) a Default or Event of Default in the
payment of the principal of, premium, if any, or interest on any Security of
such series or any coupon appertaining thereto or (ii) in respect of a covenant
or provision hereof which pursuant to Section 8.2 cannot be amended or modified
without the consent of the Holder of each Outstanding Security of such series
adversely 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 5.8. Control by Majority. The Holders of a majority in
aggregate principal amount of the Outstanding Securities of each series affected
(with each such series voting as a class) shall have the right to direct the
time,


                                       69
<PAGE>   78
method and place of conducting any proceeding for any remedy available to the
Trustee or exercising any trust or power conferred on it with respect to
Securities of that series; provided, however, that (i) the Trustee may refuse to
follow any direction that conflicts with law or this Indenture, (ii) the Trustee
may refuse to follow any direction that is unduly prejudicial to the rights of
the Holders of Securities of such series not consenting, or that would in the
good faith judgment of the Trustee have a substantial likelihood of involving
the Trustee in personal liability and (iii) the Trustee may take any other
action deemed proper by the Trustee which is not inconsistent with such
direction.

                  Section 5.9. Limitation on Suits by Holders. No Holder of any
Security of any series or any coupons appertaining thereto shall have any right
to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless:

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

                  (2) the Holders of at least 25% in aggregate principal amount
         of the Outstanding Securities of that series have made a 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
         indemnity satisfactory to the Trustee against any loss, liability or
         expense to be, or which may be, incurred by the Trustee in pursuing the
         remedy;

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

                  (5) during such 60 day period, the Holders of a majority in
         aggregate principal amount of the Out standing Securities of that
         series have not given to the Trustee a direction inconsistent with such
         written request.

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

Holder of a coupon to receive payment of interest due as provided in such
coupon, or, subject to Section 5.9, to bring suit for the enforcement of any
such payment on or after such respective dates, shall not be impaired or
affected without the consent of such Holder.

                  Section 5.11. Application of Money Collected. If the Trustee
collects any money pursuant to this Article, it shall pay out the money in the
following order, at the date or dates fixed by the Trustee and, in case of the

interest, upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

                  First:  to the Trustee for amounts due under Section 6.9;


                                       71
<PAGE>   80
                  Second: to Holders of Securities and coupons in respect of
         which or for the benefit of which such money has been collected for
         amounts due and unpaid on such Securities for principal of, premium, if
         any, and interest, ratably, without preference or priority of any kind,
         according to the amounts due and payable on such Securities for

                  Third:  to the Company.

                  The Trustee may fix a record date and payment date for any
payment to Holders pursuant to this Section 5.11. At least 15 days before such
record date, the Trustee shall mail to each holder and the Company a notice that
states the record date, the payment date and the amount to be paid.

                  Section 5.12. Restoration of Rights and Remedies. If the
Trustee or any Holder has instituted any proceeding to enforce any right or
remedy under this Indenture and such proceeding has been discontinued or
abandoned for any reason, or has been determined adversely to the Trustee or to
such Holder, then and in every such case, subject to any determination in such
proceeding, the Company, the Trustee and the Holders shall be restored severally
and respectively to their former positions hereunder and thereafter all rights
and remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

                  Section 5.13. Rights and Remedies Cumulative. Except as
otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Securities in the last paragraph of Section 3.6, no
right or remedy herein conferred upon or reserved to the Trustee or the Holders
is intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to

or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise,


                                       72

shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

                                   The Trustee

         pursuant to Section 3.3, which shall be sufficiently evidenced as
         provided therein) and any resolution of the Board of Directors may be

<PAGE>   82
                  (c) Before the Trustee acts or refrains from acting, it may
         consult with counsel or require an Officers' Certificate. The Trustee
         shall not be liable for any action it takes or omits to take in good

         acceptable to the Trustee, a certificate of an Officer or Officers
         delivered pursuant to Section 1.2, an Officers' Certificate or an
         Opinion of Counsel.

                  (d) The Trustee may act through agents or attorneys and shall
         not be responsible for the misconduct or negligence of any agent or
         attorney appointed with due care.

                  (e) The Trustee shall not be liable for any action it takes or
         omits to take in good faith which it believes to be authorized or
         within its rights or powers.

         own funds or otherwise incur any financial liability in the performance
         of any of its duties hereunder, or in the exercise of its rights or
         powers, if it shall have reasonable grounds for believing that
         repayment of such funds or indemnity deemed satisfactory by the Trustee
         against such risk or liability is not reasonably assured to it.

                  Section 6.3. Trustee May Hold Securities. The Trustee, any
Paying Agent, any Registrar or any other agent of the Company, in its individual
or any other capacity, may become the owner or pledgee of Securities and coupons
and, subject to Sections 310(b) and 311 of the Trust Indenture Act, may
otherwise deal with the Company, an Affiliate or Subsidiary with the same rights
it would have if it were not Trustee, Paying Agent, Registrar or such other
agent.

trust hereunder need not be segregated from other funds except to the extent
required by law. The


                                       74
<PAGE>   83
Trustee shall be under no liability for interest on any money received by it
hereunder except as otherwise agreed upon in writing with the Company.

                  Section 6.5. Trustee's Disclaimer. The recitals contained
herein and in the Securities, except the Trustee's certificate of
authentication, shall be taken as the statements of the Company, and the Trustee
assumes no responsibility for their correctness. The Trustee makes no

Securities or any coupon. The Trustee shall not be accountable for the Company's
use of the proceeds from the Securities or for monies paid over to the Company

                  Section 6.6. Notice of Defaults. If a Default occurs and is
continuing with respect to the Securities of any series and if it is known to
the Trustee, the Trustee shall, within 90 days after the Default occurs,
transmit by mail, in the manner and to the extent provided in Section 313(c) of
the Trust Indenture Act, notice of all Defaults known to it unless such Default
shall have been cured or waived; provided, however, that except in the case of a
Default in payment on the Securities of any series, the Trustee may withhold the
notice if and so long as a Responsible Officer in good faith determines that
withholding such notice is in the interests of Holders of Securities of that
series; and provided, further, that in the case of any Default of the character
specified in Section 5.1(3) with respect to Securities of such series, no such
notice to Holders shall be given until at least 60 days after the occurrence
thereof.

Indenture Act a brief report dated

                                       75

as of such May 15 if required by and in compliance with Section 313(a) of the
Trust Indenture Act.

                  Section 6.8. Securityholder Lists. The Trustee shall preserve
in as current a form as is reasonably practicable the most recent list available
to it of the names and addresses of Holders of Securities of each series. If the
Trustee is not the Registrar, the Company shall furnish to the Trustee
semiannually on or before the last day of June and December in each year, and at
such other times as the Trustee may request in writing, a list, in such form and
as of such date as the Trustee may reasonably require, containing all the
information in the possession or control of the Registrar, the Company or any of
its Paying Agents other than the Trustee as to the names and addresses of
Holders of Securities of each such series. If there are Bearer Securities of any
series Outstanding, even if the Trustee is the Registrar, the Company shall
furnish to the Trustee such a list containing such information with respect to
Holders of such Bearer Securities only.

                  Section 6.9. Compensation and Indemnity. (a) The Company shall
pay to the Trustee from time to time reasonable compensation for its services.
The Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee upon
request for all reasonable out-of-pocket expenses incurred by it in connection
with the performance of its duties under this Indenture, except any such expense
as may be attributable to its negligence or bad faith. Such expenses shall
include the reasonable compensation and expenses of the Trustee's agents and
counsel.

                  (b) The Company shall indemnify the Trustee for, and hold it
harmless against, any loss or liability, damage, claim or reasonable expense
including taxes (other than taxes based upon or determined or measured by the
income of the Trustee) incurred by it arising out of or in connection with its
acceptance or administration of the trust or trusts

                                       76
<PAGE>   85
hereunder, including the reasonable costs and expenses of defending itself
against any claim or liability in connection with the exercise or performance of
any of its powers or duties hereunder. The Trustee shall notify the Company
promptly of any claim for which it may seek indemnity. The Company shall defend
the claim and the Trustee shall cooperate in the defense. The Trustee may have
separate counsel and the Company shall pay the reasonable fees and expenses of
such counsel. The Company need not pay for any settlement made without its
consent.

                  (c) The Company agrees to pay the fees and expenses of
Trustee's counsel in connection with the review, revision, preparation and
delivery of this Indenture on the date of the execution of this Indenture by
check or wire transfer payable to White & Case.

                  (d) The Company need not reimburse any expense or indemnify
against any loss or liability incurred by the Trustee through negligence or bad
faith.

                  (e) To secure the payment obligations of the Company pursuant
to this Section, the Trustee shall have a lien prior to the Securities of any
series on all money or property held or collected by the Trustee, except that
held in trust to pay principal, premium, if any, and interest on particular
Securities.

                  When the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 5.1(5) or Section
5.1(6), the expenses (including the reasonable fees and expenses of its counsel)
and the compensation for the services are intended to constitute expenses of
administration under any applicable Federal or state bankruptcy, insolvency or
other similar law.

                  The provisions of this Section shall survive the resignation
or removal of the Trustee and the termination of this Indenture.

<PAGE>   86
                  Section 6.10. Replacement of Trustee. (a) The resignation or
removal of the Trustee and the appointment of a successor Trustee shall become
effective only upon the successor Trustee's acceptance of appointment as
provided in Section 6.11.

                  (b) The Trustee may resign at any time with respect to the
Securities of any series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 6.11 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 Holders of a majority in aggregate principal amount of
the Outstanding Securities of any series may remove the Trustee with respect to
that series by so notifying the Trustee and the Company and may appoint a
successor Trustee for such series with the Company's consent.

                  (d)  If at any time:

                  (1) the Trustee fails to comply with Section 310(b) of the
         Trust Indenture Act after written request therefor by the Company or by
         any Holder who has been a bona fide Holder of a Security for at least
         six months, or

                  (2) the Trustee shall cease to be eligible under Section
         310(a) of the Trust Indenture Act and shall fail to resign after
         written request therefor by the Company or by any Holder of a Security
         who has been a bona fide Holder of a Security for at least six months;
         or

                  (3)  the Trustee becomes incapable of acting, is
         adjudged a bankrupt or an insolvent or a receiver or

                                       78
<PAGE>   87
         public officer takes charge of the Trustee or 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 (ii) subject to Section
315(e) of the Trust Indenture Act, any Holder who has been a bona fide Holder of
a Security for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the removal
of the Trustee with respect to all Securities and the appointment of a successor
Trustee or Trustees.

                  (e) If the Trustee resigns or is removed or if a vacancy
exists in the office of Trustee for any reason, with respect to Securities of
one or more series, the Company, by or pursuant to Board Resolution, shall
promptly appoint a successor Trustee 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 6.11. 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 6.11, become the
successor Trustee with respect to the Securities of such series and to that
extent supersede the successor Trustee appointed by the Company. If no successor
Trustee with respect to the Securities of any series shall have been so
appointed by the Company or the Holders and accepted appointment in the manner
required by Section 6.11, any Holder who has been a bona fide Holder of a
Security of such

                                       79
<PAGE>   88
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.

                  Section 6.11. Acceptance of Appointment by Successor. (a) In
case of the appointment hereunder of a successor Trustee with respect to all
Securities, every such successor Trustee shall execute, acknowledge and deliver
to the Company and to the retiring Trustee an instrument accepting such
appointment. Thereupon, the resignation or removal of the retiring Trustee shall
become effective, and the successor Trustee, without further act, deed or
conveyance, shall become vested with all the rights, powers and duties of the
retiring Trustee; but, on the request of the Company or the successor Trustee,
such retiring Trustee shall, upon payment of its charges, execute and deliver an
instrument transferring to such successor Trustee all the rights, powers and
trusts of the retiring Trustee and shall duly assign, transfer and deliver to
such successor Trustee all property and money held by such retiring Trustee
hereunder.

                  (b) In case of the appointment hereunder of a successor
Trustee with respect to the Securities of one or more (but not all) series, the
Company, the retiring Trustee and such successor Trustee shall execute and
deliver an indenture supplemental hereto wherein such successor Trustee shall
accept such appointment and which (i) 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, (ii) 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

                                       80
<PAGE>   89
retiring shall continue to be vested in the retiring Trustee, and (iii) shall
add to or change any of the provisions of this Indenture as shall be necessary
to provide for or facilitate the administration of the trusts hereunder by more
than one Trustee, it being understood that nothing herein or in such
supplemental indenture shall constitute such Trustees co-trustees of the same
trust and that each such Trustee shall be trustee of a trust or trusts hereunder
separate and apart from any trust or trusts hereunder administered by any other
such Trustee and upon the execution and delivery of such supplemental indenture
the resignation or removal of the retiring Trustee shall become effective to the
extent provided therein and each such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the retiring Trustee with respect to the Securities of that or
those series to which the appointment of such successor Trustee relates; but, on
request of the Company or any successor Trustee, such retiring Trustee shall
duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder with respect to the Securities of
that or those series to which the appointment of such successor Trustee relates.

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

                  (d) No successor Trustee shall accept its appointment unless
at the time of such acceptance such successor Trustee shall be qualified and
eligible under the Trust Indenture Act.

                  (e) The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a

                                       81
<PAGE>   90
successor Trustee with respect to the Securities of any series in the manner
provided for notices to the Holders of Securities in Section 1.6. Each notice
shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust office. If the Company
fails to give such notice within thirty days after acceptance of appointment by
the successor Trustee, the successor Trustee shall cause such notice to be given
at the expense of the Company.

                  Section 6.12. Eligibility; Disqualification. There shall at
all times be a Trustee hereunder which shall be eligible to act as Trustee under
Section 310(a)(1) of the Trust Indenture Act and shall have a combined capital
and surplus of at least $75,000,000. If such corporation publishes reports of
condition at least annually, pursuant to law or the requirements of Federal,
State, Territorial or District of Columbia supervising or examining authority,
then for the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect hereinafter specified
in this Article.

                  Section 6.13. Merger, Conversion, Consolidation or Succession
to Business. Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor

                                       82
<PAGE>   91
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 6.14. Appointment of Authenticating Agent. The Trustee
may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of such series issued upon original issue, exchange,
registration of transfer or partial redemption thereof, and Securities so
authenticated shall be entitled to the benefits of this Indenture and shall be
valid and obligatory for all purposed as if authenticated by the Trustee
hereunder. Any such appointment shall be evidenced by an instrument in writing
signed by a Responsible Officer of the Trustee, a copy of which instrument
shall be promptly furnished to the Company. Wherever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and, except as may otherwise be provided pursuant to
Section 3.1, shall at all times be a bank or trust company or corporation
organized and doing business and in good standing under the laws of the United
States of America or of any State or the District of Columbia, authorized under
such laws to act as Authenticating Agent, having a combined capital and surplus
of not less than $5,000,000 and subject to supervision or examination by Federal
or State authorities. If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such Authenticating Agent shall be
deemed to be its

                                       83
<PAGE>   92
combined capital and surplus as set forth in its most recent report of condition
so published. In case at any time an Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, such Authenticating
Agent shall resign immediately in the manner and with the effect specified in
this Section.

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

                  An Authenticating Agent for any series of Securities may at
any time resign by giving written notice of resignation to the Trustee for such
series and to the Company. The Trustee for any series of Securities may at any
time terminate the agency of an Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Company. 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 for such series may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall give
notice of such appointment to all Holders of Securities of the series with
respect to which such Authenticating Agent will serve in the manner set forth in
Section 1.6. 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 herein. No successor Authenticating Agent shall be

                                       84

appointed unless eligible under the provisions of this Section.

                  The Company agrees to pay to each Authenticating Agent from
time to time reasonable compensation including reimbursement of its reasonable
expenses for its services under this Section.

                  If an appointment with respect to one or more series is made
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 substantially in the
following form:

                  This is one of the Securities of the series described in the
within-mentioned Indenture.

provided in clause (2) above, such successor corporation shall succeed to and be
substituted for the Company hereunder and under the Securities and any coupons
appertaining thereto and all such obligations of the Company shall terminate.

         benefit of such series) or to surrender any right or power herein
         conferred upon the Company; or

                  (3)  to add any additional Events of Default with

         issuance of Bearer Securities (including, without limitation, to
         provide that Bearer Securities may be registrable as to principal only)
         or to facilitate the issuance of Securities in global form; or

                  (5) to change or eliminate any of the provisions of this
         Indenture, provided that any such change or elimination shall become
         effective only if it does not affect any Security Outstanding of any
         series created prior to the execution of such supplemental indenture
         that is entitled to the benefit of such provision; or

                  (6)  to secure the Securities; or

         the states and the District of Columbia), its territories, its
         possessions and other areas subject to its jurisdiction of principal,
         premium, if any, or interest, if any, on Bearer Securities or coupons,
         if any; or

             (10) to correct or supplement any provision herein which may be
         inconsistent with any other provision herein or to make any other
         provisions with respect to matters or questions arising under this
         Indenture, provided such action shall not adversely affect the
         interests of the Holders of Securities of any series; or

             (11)  to cure any ambiguity or correct any mistake.

                  Section 8.2. Supplemental Indentures With Consent of Holders.

and the Trustee may enter into an indenture or indentures supplemental hereto
to add any provisions to or to change or eliminate any provisions of this
Indenture or of any other indenture supplemental hereto or to modify the rights

this Section may not:

                                       88
<PAGE>   97
                  (1) change the Stated Maturity of the principal of or premium,
         if any, on, or any installment of principal of or premium, if any, or
         interest on, any Security, or reduce the principal amount thereof or
         the rate of interest thereon or any premium payable upon the redemption
         thereof, or change the manner in which the amount of any principal
         thereof or premium, if any, or interest thereon is determined or reduce
         the amount of the principal of any Original Issue Discount Security or

         payment on or after the Stated Maturity thereof (or, in the case of
         redemption, on or after the Redemption Date);

                  (2) reduce the percentage in principal amount of the

         consequences) provided for in this Indenture;

         or agency in the places and for the purposes specified in Section 9.2;

         increase any percentage or to provide that certain other provisions of
         this Indenture cannot be modified or waived with the consent of the
         Holders of each Outstanding Security affected thereby.

                  A supplemental indenture which changes or eliminates any
covenant or other provision of this Indenture

                                       89
<PAGE>   98
which has expressly been included solely for the benefit of one or more
particular series of Securities, or which modifies the rights of the Holders of
Securities of such series with respect to such covenant or other provision,
shall be deemed not to affect the rights under this Indenture of the Holders of
Securities of any other series.

                  It is not necessary under this Section 8.2 for the Holders to
consent to the particular form of any proposed supplemental indenture, but it is
sufficient if they consent to the substance thereof.

                  Section 8.3. Compliance with Trust Indenture Act. Every
amendment to this Indenture or the Securities of one or more series shall be set
forth in a supplemental indenture that complies with the Trust Indenture Act as
then in effect.

                  Section 8.4. Execution of Supplemental Indentures. In
executing, or accepting the additional trusts created by, any supplemental
indenture permitted by this Article or the modification thereby of the trusts
created by this Indenture, the Trustee shall be entitled to receive, and shall
be fully protected in relying upon, an Opinion of Counsel stating that the
execution of such supplemental indenture is authorized or permitted by this
Indenture. The Trustee may, but shall not be obligated to, enter into any such
supplemental indenture which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

                  Section 8.5. Effect of Supplemental Indentures. Upon the
execution of any supplemental indenture under this article, this Indenture shall
be modified in accordance therewith, and such supplemental indenture shall form
a part of this Indenture for all purposes; and every Holder of Securities
theretofore or thereafter authenticated and delivered hereunder and of any
coupon appertaining thereto shall be bound thereby.

                  Section 8.6. Reference in Securities to Supplemental
Indentures. Securities, including any coupons, of any series authenticated and
delivered after the execution of any supplemental indenture pursuant to this
Article may, and shall if required by the Trustee, bear a notation in form
approved by the Trustee as to any matter provided for in such supplemental
indenture. If the Company shall so determine, new Securities including any
coupons of any series so modified as to conform, in the opinion of the Trustee
and the Company, to any such supplemental indenture may be prepared and executed
by the Company and authenticated and delivered by the Trustee in exchange for
Outstanding Securities including any coupons of such series.


                                    ARTICLE 9

                                    Covenants

                  Section 9.1. Payment of Principal, Premium, if Any, and
Interest. The Company covenants and agrees for the benefit of the Holders of
each series of Securities that it will duly and punctually pay the principal of,
premium, if any, and interest together with additional amounts, if any, on the
Securities of that series in accordance with the terms of the Securities of such
series, any coupons appertaining thereto and this Indenture. An installment of
principal, premium, if any, or interest shall be considered paid on the date it
is due if the Trustee or Paying Agent holds on that date money designated for
and sufficient to pay the installment.

                  Section 9.2. Maintenance of Office or Agency. If Securities of
a series are issued as Registered Securities, the Company will maintain in each
Place of Payment for any series of Securities an office or agency where
Securities of that series may be presented or surrendered for payment, where
Securities of that series may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Company in respect of the
Securities

                                       91
<PAGE>   100
of that series and this Indenture may be served. If Securities of a series are
issuable as Bearer Securities, the Company will maintain, (i) subject to any
laws or regulations applicable thereto, an office or agency in a Place of
Payment for that series which is located outside the United States where
Securities of that series and related coupons may be presented and surrendered
for payment; provided, however, that if the Securities of that series are listed
on The International Stock Exchange of the United Kingdom and the Republic of
Ireland Limited, the Luxembourg Stock Exchange or any other stock exchange
located outside the United States and such stock exchange shall so require, the
Company will maintain a Paying Agent for the Securities of that series in
London, Luxembourg or any other required city located outside the United States,
as the case may be, so long as the Securities of that series are listed on such
exchange, and (ii) subject to any laws or regulations applicable thereto, an
office or agency in a Place of Payment for that series which is located outside
the United States, where Securities of that series may be surrendered for
exchange and where notices and demands to or upon the Company in respect of the
Securities of that series and this Indenture may be served. The Company will
give prompt written notice to the Trustee of the location, and any change in the
location, of any 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, and the
Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

                  Unless otherwise specified as contemplated by Section 3.1, no
payment of principal, premium or interest on Bearer Securities shall be made at
any office or agency of the Company in the United States, by check mailed to any
address in the United States, by transfer to an account located in the United
States or upon presentation or surrender in the United States of a Bearer
Security or

                                       92
<PAGE>   101
coupon for payment, even if the payment would be credited to an account located
outside the United States; provided, however, that, if the Securities of a
series are denominated and payable in Dollars, payment of principal of and any
premium or interest on any such Bearer Security shall be made at the office of
the Company's Paying Agent in the Borough of Manhattan, The City of New York, if
(but only if) payment in Dollars of the full amount of such principal, premium
or interest, as the case may be, at all offices or agencies outside the United
States maintained for the purpose by the Company in accordance with this
Indenture is illegal or effectively precluded by exchange controls or other
similar restrictions.

                  The Company may also from time to time designate one or more
other offices or agencies where the Securities (including any coupons, if any)
of one or more series may be presented or surrendered for any or all such
purposes and may from time to time rescind such designations; provided, however,
that no such designation or rescission shall in any manner relieve the Company
of its obligation to maintain an office or agency in each Place of Payment for
Securities (including any coupons, if any) of any series for such purposes. The
Company will give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency.

                  Unless otherwise specified as contemplated by Section 3.1,
the Trustee shall initially serve as Paying Agent.

                  Section 9.3. Money for Securities Payments to Be Held in
Trust; Unclaimed Money. If the Company shall at any time act as its own Paying
Agent with respect to any series of Securities, it will, on or before each due
date of the principal of, premium, if any, or interest on any of the Securities
of that series, segregate and hold in trust for the benefit of the Persons
entitled thereto a sum sufficient to pay the principal, premium, if any, or
interest so becoming due until such sums shall be paid to such Persons or
otherwise disposed of as herein provided and will promptly

                                       93
<PAGE>   102
notify the Trustee in writing of its action or failure so to act.

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

                  (1) hold all sums held by it for the payment of the principal
         of, premium, if any, or interest on Securities of that series in trust
         for the benefit of the Persons entitled thereto until such sums shall
         be paid to such Persons or otherwise disposed of as herein provided;

                  (2) give the Trustee notice of any default by the Company (or
         any other obligor upon the Securities of that series) in the making of
         any payment of principal, premium, if any, or interest on the
         Securities; and

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

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

                  Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of any principal, premium or
interest on any Security of any

                                       94
<PAGE>   103
series and remaining unclaimed for two years after such principal, premium, if
any, or interest has become due and payable shall be paid to the Company on
Company Request, or (if then held by the Company) shall be discharged from such
trust; and the Holder of such Security and coupon, if any, shall thereafter, as
an unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in The City of New
York, or cause to be mailed to such Holder, 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, any unclaimed balance of such money
then remaining will be repaid to the Company.

                  Section 9.4. Corporate Existence. Subject to Article 7, the
Company will at all times do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence and its
rights and franchises; provided that nothing in this Section 9.4 shall prevent
the abandonment or termination of any right or franchise of the Company if, in
the opinion of the Company, such abandonment or termination is in the best
interests of the Company and not prejudicial in any material respect to the
Holders of the Securities.

                  Section 9.5. Insurance. The Company covenants and agrees that
it will maintain, and cause each of its Subsidiaries to maintain, insurance with
responsible and reputable insurance companies or associations in such amounts
and covering such risks as are consistent with sound business practice for
corporations engaged in the same or a similar business similarly situated. In
lieu of the foregoing or in combination therewith, in case of itself or

                                       95
<PAGE>   104
of any one or more of its Subsidiaries, the Company will maintain or cause to be
maintained a system or systems of self-insurance which will accord with the
financially sound and approved practices of companies owning or operating
properties of a similar character and maintaining such systems. The Trustee
shall not be required to see that such insurance is effected or maintained.

                  Section 9.6. Reports by the Company. The Company covenants:

                  (a) to file with the Trustee, within 30 days after the Company
         is required to file the same with the Commission, copies of the annual
         reports and of the information, documents and other reports (or copies
         of such portions of any of the foregoing as the Commission may from
         time to time by rules and regulations prescribe) which the Company may
         be required to file with the Commission pursuant to Section 13 or
         Section 15(d) of the Securities Exchange Act of 1934, as amended; or,
         if the Company is not required to file information, documents or
         reports pursuant to either of such sections, then to file with the
         Trustee and the Commission, in accordance with rules and regulations
         prescribed from time to time by the Commission, such of the
         supplementary and periodic information, documents and reports which may
         be required pursuant to Section 13 of the Securities Exchange Act of
         1934, as amended, in respect of a security listed and registered on a
         national securities exchange as may be prescribed from time to time in
         such rules and regulations;

                  (b) to file with the Trustee and the Commission, in accordance
         with the rules and regulations prescribed from time to time by the
         Commission, such additional information, documents and reports with
         respect to compliance by the Company with the conditions and covenants
         provided for in this Indenture, as may be required from time to time by
         such rules and regulations; and

                                       96
<PAGE>   105
                  (c) to transmit to all Holders of Securities, within 30 days
         after the filing thereof with the Trustee, in the manner and to the
         extent provided in Section 313(c) of the Trust Indenture Act, such
         summaries of any information, documents and reports required to be
         filed by the Company pursuant to subsections (a) and (b) of this
         Section 9.6, as may be required by rules and regulations prescribed
         from time to time by the Commission.

                  Section 9.7. Annual Review Certificate. The Company covenants
and agrees to deliver to the Trustee, within 120 days after the end of each
fiscal year of the Company, a certificate from the principal executive officer,
principal financial officer or principal accounting officer as to his or her
knowledge of the Company's compliance with all conditions and covenants under
this Indenture. For purposes of this Section 9.7, such compliance shall be
determined without regard to any period of grace or requirement of notice
provided under this Indenture.

                  Section 9.8. Books of Record and Account. The Company will
keep proper books of record and account, either on a consolidated or individual
basis. The Company shall cause its books of record and account to be examined,
either on a consolidated or individual basis, by one or more firms of
independent public accountants not less frequently than annually. The Company
shall prepare its financial statements in accordance with generally accepted
accounting principles.

                  Section 9.9. Limitation on Liens. (a) The Company will not,
nor will it permit any Restricted Subsidiary to, (i) issue, assume or guarantee
any Debt, if such Debt is secured by a mortgage, pledge, security interest or
lien (any mortgage, pledge, security interest or lien being hereinafter in this
Article Nine referred to as a "mortgage" or "mortgages") upon, or (ii) directly
or indirectly secure any outstanding Debt by a mortgage upon, any Principal
Property, now owned or hereafter acquired, without in any

                                       97
<PAGE>   106
such case effectively providing, concurrently with the issuance, assumption or
guarantee of any such Debt, or the granting of security with respect to any such
outstanding Debt, that the Securities (together with, if the Company shall so
determine, any other indebtedness of or guaranteed by the Company or such
Restricted Subsidiary ranking equally with the Securities and then existing or
thereafter created) shall be secured equally and ratably with (or prior to) such
Debt; provided, however, that the foregoing restriction shall not apply to

                  (1) mortgages on any Principal Property acquired, constructed
         or improved by the Company or any Restricted Subsidiary after the date
         of this Indenture which are created or assumed contemporaneously with,
         or within 90 days after, such acquisition, construction or improvement
         to secure or provide for the payment of any part of the purchase price
         of such property or the cost of such construction or improvement
         incurred after the date of this Indenture, or, in addition to mortgages
         contemplated by clause (2) below, mortgages on any Principal Property
         existing at the time of acquisition thereof, provided that in the case
         of any such acquisition, construction or improvement the mortgage
         shall not apply to any property theretofore owned by the Company or any
         Restricted Subsidiary, other than in the case of any such construction
         or improvement, any theretofore unimproved real property on which the
         property so constructed, or the improvement, is located;

                  (2) mortgages on any Principal Property acquired from a
         corporation which is merged with or into the Company or a Restricted
         Subsidiary;

                  (3) mortgages to secure Debt of a Restricted Subsidiary to the
         Company or to another Restricted Subsidiary; and

                                       98
<PAGE>   107
                  (4) any extension, renewal or replacement (or successive
         extensions, renewals or replacements), in whole or in part, of any
         mortgage referred to in the foregoing clauses (1) to (3), inclusive;
         provided, however, that the principal amount of Debt secured thereby
         shall not exceed the principal amount of Debt so secured at the time of
         such extension, renewal or replacement, and that such extension,
         renewal or replacement shall be limited to all or part of the property
         which secured the mortgage so extended, renewed or replaced (plus
         improvements on such property).

                  (b) Notwithstanding the provisions of subsection (a) of this
Section 9.9, the Company or any Restricted Subsidiary may issue, assume or
guarantee secured Debt which would otherwise be subject to the foregoing
restrictions in an aggregate amount which, together with all other such Debt of
the Company and its Restricted Subsidiaries and the Attributable Debt in respect
of Sale and Lease-Back Transactions (as defined in Section 9.10) existing at
such time (other than Sale and Lease-Back Transactions permitted because the
Company would be entitled to incur Debt secured by a mortgage on the property to
be leased without equally and ratably securing the Securities pursuant to
paragraph (a) of this Section 9.9 and other than Sale and Lease-Back
Transactions the proceeds of which have been applied in accordance with the
limitations on Sale and Lease-Back Transactions set forth in paragraph (a) of
Section 9.10), does not at the time exceed 15% of the shareholders' equity in
the Company and its consolidated Subsidiary companies, as shown on the audited
consolidated balance sheet contained in the latest annual report to shareholders
of the Company.

                  (c)  For the purposes of Sections 9.9 and 9.10,

                  (1) the following types of transactions, among others, shall
         not be deemed to create Debt secured by a mortgage:

<PAGE>   108
                           (a) the sale or other transfer of (i) any minerals in
                  place for a period of time until, or in an amount such that,
                  the purchaser will realize therefrom a specified amount of
                  money (however determined) or a specified amount of such
                  minerals, or (ii) any other interest in property of the
                  character commonly referred to as a "production payment"; and

                           (b) mortgages in favor of the United States of
                  America, any of its territories or possessions, or any State
                  thereof, or any department, agency, instrumentality or
                  political subdivision of any thereof, or any department,
                  agency or instrumentality of any such political subdivision,
                  to secure partial progress, advance or other payments pursuant
                  to any contract or statute or to secure any indebtedness
                  incurred for the purpose of financing all or any part of the
                  purchase price or the cost of constructing or improving the
                  property subject to such mortgages;

                  (2) the term "Attributable Debt" shall mean, as of any
         particular time, the present value, discounted at a rate per annum
         equal to the weighted average of the interest rate(s) borne by the
         Securities, or, in the case of Original Issue Discount Securities, the
         Yield(s) to Maturity, compounded semi-annually, of the obligation of a
         lessee for rental payments (not including amounts payable by the lessee
         for maintenance, property taxes and insurance) during the remaining
         term of any lease (including any period for which such lease has been
         extended or may, at the option of the lessor, be extended);

                  (3) the term "Principal Property" shall mean any mineral
         property, concentrator, smelter, refinery, or rod mill, located within
         the United States of America or its territories or possessions of the
         Company or any Restricted Subsidiary except any such property or plant

                                      100
<PAGE>   109
         which the Board of Directors by resolution declares is not of material
         importance to the total business conducted by the Company and its
         Restricted Subsidiaries as an entity;

                  (4) the term "Restricted Subsidiary" shall mean (i) any
         Subsidiary which owns or leases, directly or indirectly, a Principal
         Property and (ii) any Subsidiary which owns, directly or indirectly,
         stock or indebtedness of a Restricted Subsidiary, provided, however,
         that the term "Restricted Subsidiary" shall not mean any Subsidiary (x)
         engaged primarily in financing receivables, making loans, extending
         credit or other activities of a character conducted by a finance
         company or (y) which conducts substantially all of its business outside
         the United States of America and its territories or possessions or the
         principal assets of which are stock or indebtedness of corporations
         which conduct substantially all of their business outside the United
         States of America and its territories or possessions.

                  (5) the term "shareholders' equity in the Company and its
         consolidated Subsidiary companies" shall mean the consolidated capital
         stock, capital surplus, if any, and retained earnings of the Company
         and its consolidated Subsidiary companies, after deducting the cost of
         shares of the Company held in its treasury.

                  Section 9.10. Limitation on Sale and Lease-Back. (a) The
Company will not, nor will it permit any Restricted Subsidiary to, enter into
any arrangement with any person providing for the leasing by the Company or a
Restricted Subsidiary of any Principal Property (except for temporary leases for
a term of not more than three years), title to which property has been or is to
be sold or transferred by the Company or such Restricted Subsidiary to such
person (herein referred to as "Sale and Lease-Back Transaction"), unless the
proceeds of such sale or transfer are at least equal to the fair value (as
determined by the Board of

                                      101
<PAGE>   110
Directors) of such property and either (i) the Company or such Restricted
Subsidiary would be entitled to incur Debt secured by a mortgage on the property
to be leased without equally and ratably securing the Securities pursuant to
Section 9.9 or (ii) the Company shall, and in any such case the Company
covenants that it will, apply an amount equal to the fair value (as determined
by the Board of Directors) of the property so leased to the retirement (other
than any mandatory retirement), within 90 days of the effective date of any such
Sale and Lease-Back Transaction, of Debt of the Company which by its terms
matures at, or is extendible or renewable at the option of the obligor to, a
date more than twelve months after the date of the creation of such Debt and
which ranks prior to or on a parity with the Securities; provided, however, that
the term Sale and Lease-Back Transaction shall not include any arrangement with
the United States of America, any of its territories or possessions, or any
State thereof, or any department, agency, instrumentality or political
subdivision of any thereof, or any department, agency or instrumentality of any
such political subdivision, entered into for the purpose of financing all or any
part of the purchase price or the cost of constructing or improving the property
subject to such arrangement.

                  (b) Notwithstanding the provisions of the preceding paragraph
(a), the Company or any Restricted Subsidiary may enter into any Sale and
Lease-Back Trans action which would otherwise be subject to the foregoing
restrictions if the amount of the Attributable Debt in respect of Sale and
Lease-Back Transactions for such transaction, together with all secured Debt of
the Company and its Restricted Subsidiaries and all other Attributable Debt in
respect of Sale and Lease-Back Transactions existing at such time (other than
Sale and Lease-Back Transactions permitted because the Company would be entitled
to incur Debt secured by a mortgage on the property to be leased without equally
and ratably securing the Securities and other than Sale and Lease-Back
Transactions the proceeds of which have been applied in accordance with clause
(ii) of

                                      102
<PAGE>   111

                                   Redemption

                  Section 10.1. Applicability of Article. Securities (including
coupons, if any) of any series which are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified as contemplated by Section 3.1 for Securities of any series) in
accordance with this Article.

                  Section 10.2. Election to Redeem; Notice to Trustee. The
election of the Company to redeem any Securities, including coupons, if any,
shall be evidenced by or pursuant to a Board Resolution. In the case of any
redemption at the election of the Company of less than all the Securities or
coupons, if any, of any series, the Company shall, at least 60 days prior to the
Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the
principal amount of Securities of such series to be redeemed and, if applicable,
of the tenor of the Securities to be redeemed. In the case of any redemption of
Securities (i) prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture or (ii)
pursuant to an election of the Company which is subject to a condition specified
in the terms of such Securities, the Company shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction or condition.

<PAGE>   112
                  Section 10.3. Selection of Securities to Be Redeemed. Unless
otherwise specified as contemplated by Section 3.1, if less than all the
Securities (including coupons, if any) of a series with the same terms are to be
redeemed, the Trustee, not more than 45 days prior to the redemption date, shall
select the Securities of the series to be redeemed in such manner as the Trustee
shall deem fair and appropriate. The Trustee shall make the selection from
Securities of the series that are Outstanding and that have not previously been
called for redemption and may provide for the selection for redemption of
portions (equal to the minimum authorized denomination for Securities, including
coupons, if any, of that series or any integral multiple thereof) of the
principal amount of Securities, including coupons, if any, of such series of a
denomination larger than the minimum authorized denomination for Securities of
that series. The Trustee shall promptly notify the Company in writing of the
Securities selected by the Trustee for redemption and, in the case of any
Securities selected for partial redemption, the principal amount thereof to be
redeemed.

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

                  Section 10.4. Notice of Redemption. Unless otherwise specified
as contemplated by Section 3.1, notice of redemption shall be given in the
manner provided in Section 1.6 not less than 30 days nor more than 60 days
prior to the Redemption Date to the Holders of the Securities to be redeemed.

                  All notices of redemption shall state:

                  (1)      the Redemption Date;

                                      104
<PAGE>   113
                  (2) the Redemption Price;

                  (3) if less than all the Outstanding Securities of a series
         are to be redeemed, the identification (and, in the case of partial
         redemption, the principal amounts) of the particular Security or
         Securities to be redeemed;

                  (4) 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 will
         receive, without a charge, a new Security or Securities of authorized
         denominations for the principal amount thereof remaining unredeemed;

                  (5) the Place or Places of Payment 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 for the Redemption Price;

                  (6) that Securities of the series called for redemption and
         all unmatured coupons, if any, appertaining thereto must be
         surrendered to the Paying Agent to collect the redemption price;

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

                  (8) that the redemption is for a sinking fund, if such is the
         case;

                  (9) 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 Redemption Date
         or

                                      105
<PAGE>   114
         the amount of any such missing coupon or coupons will be deducted from
         the Redemption Price, unless security or indemnity satisfactory to the
         Company, the Trustee and any Paying Agent is furnished; and

             (10)  the CUSIP number, if any, of the Securities.

                  Notice of redemption of Securities to be redeemed 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 10.5. Deposit of Redemption Price. On or prior to any
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, which it may not do
in the case of a sinking fund payment under Article 11, segregate and hold in
trust as provided in Section 9.3) an amount of money in the currency or
currencies (including currency unit or units) in which the Securities of such
series are payable (except as otherwise specified pursuant to Section 3.1 for
the Securities of such series) sufficient to pay on the Redemption Date the
Redemption Price of, and (unless the Redemption Date shall be an Interest
Payment Date) interest accrued to the Redemption Date on, all Securities or
portions thereof which are to be redeemed on that date.

                  Unless any Security by its terms prohibits any sinking fund
payment obligation from being satisfied by delivering and crediting Securities
(including Securities redeemed otherwise than through a sinking fund), the
Company may deliver such Securities to the Trustee for crediting against such
payment obligation in accordance with the terms of such Securities and this
Indenture.

                  Section 10.6. 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

                                      106
<PAGE>   115
shall default in the payment of the Redemption Price and accrued interest) such
Securities shall cease to bear interest and the coupons for any such interest
appertaining to any Bearer Security so to be redeemed, except to the extent
provided below, shall be void. Except as provided in the next succeeding
paragraph, upon surrender of any such Security, including coupons, if any, for
redemption in accordance with said notice, such Security shall be paid by the
Company at the Redemption Price, together with accrued interest to the
Redemption Date; provided, however, that installments of interest on Bearer
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable only at an office or agency located outside the United States and its
possessions (except as otherwise provided in Section 9.2) and, unless otherwise
specified as contemplated by Section 3.1, only upon presentation and surrender
of coupons for such interest; and provided, further, that, unless otherwise
specified as contemplated by Section 3.1, installments of interest on Registered
Securities whose Stated Maturity is on or prior to the Redemp tion Date shall
be payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 3.7.

                  If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Bearer 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 Bearer
Security shall surrender to the Trustee or any Paying Agent any such missing
coupon in respect of which a deduction shall have been made from the Redemption
Price, such Holder shall be entitled to receive the amount so deducted;
provided, however, that interest represented by coupons shall be payable only at
an office or

                                      107
<PAGE>   116
agency located outside of the United States (except as otherwise provided
pursuant to Section 9.2) and, unless otherwise specified as contemplated by
Section 3.1, only upon presentation and surrender of those coupons.

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

                  Section 10.7. Securities Redeemed in Part. Upon surrender of a
Security that is redeemed in part at any Place of Payment therefor (with, if the
Company or the Trustee so required, 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), the Company
shall execute and the Trustee shall authenticate and deliver to the Holder of
that Security, without service charge a new Security or Securities of the same
series, having the same form, terms and Stated Maturity, in any authorized
denomination equal in aggregate principal amount to the unredeemed portion of
the principal amount of the Security surrendered.


                                   ARTICLE 11

                                  Sinking Funds

                  Section 11.1. Applicability of Article. The provisions of this
Article shall be applicable to any sinking fund for the retirement of Securities
of a series except as otherwise specified as contemplated by Section 3.1 for
Securities of such series.

                  The minimum amount of any sinking fund payment provided for by
the terms of Securities of any series is herein referred to as a "mandatory
sinking fund payment,"

                                      108
<PAGE>   117
and any payment in excess of such minimum amount provided for by the terms of
Securities of any series is herein referred to as an "optional sinking fund
payment." If provided for by the terms of Securities of any series, the cash
amount of any sinking fund payment may be subject to reduction as provided in
Section 11.2. Each sinking fund payment shall be applied to the redemption of
Securities of any series as provided for by the terms of Securities of such
series.

                  Section 11.2. Satisfaction of Sinking Fund Payments with
Securities. The Company (i) may deliver Outstanding Securities of a series
(other than any previously called for redemption) together, in the case of
Bearer Securities of such series, with all unmatured coupons appertaining
thereto and (ii) may apply as a credit Securities of a series which have been
redeemed either at the election of the Company pursuant to the terms of such
Securities or through the application of permitted optional sinking fund
payments pursuant to the terms of such Securities, in each case in satisfaction
of all or any part of any sinking fund payment with respect to the Securities of
such series required to be made pursuant to the terms of such Securities as
provided for by the terms of such series; provided that such Securities have not
been previously so credited. Such Securities shall be received and credited for
such purpose by the Trustee at the Redemption Price specified in such Securities
for redemption through operation of the sinking fund and the amount of such
sinking fund payment shall be reduced accordingly.

                  Section 11.3. Redemption of Securities for Sinking Fund. Not
less than 60 days prior to each sinking fund payment date for any series of
Securities, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied by delivering and crediting

                                      109
<PAGE>   118
Securities of that series pursuant to Section 11.2 and will also deliver to the
Trustee any Securities to be so delivered. Not less than 30 days before each
such sinking fund payment date the Trustee shall select the Securities to be
redeemed upon such sinking fund payment date in the manner specified in Section
10.3 and cause notice of the redemption thereof to be given in the name of and
at the expense of the Company in the manner provided in Section 10.4. Such
notice having been duly given, the redemption of such Securities shall be made
upon the terms and in the manner stated in Sections 10.6 and 10.7.




                  This Indenture may be executed in any number of counterparts,
each of which shall be an original, but such counterparts shall together
constitute but one instrument.

                       Registration Statement on Form S-3
                             (filed September 25, 1997)

Ladies and Gentlemen:

            We have acted as counsel to Phelps Dodge Corporation, a New York
corporation (the "Company"), in connection with the preparation and filing with
the Securities and Exchange Commission (the "Commission") under the Securities
Act of 1933, as amended (the "Act"), of the Company's Registration Statement and
Post-Effective Amendment No. 1 (filed September 25, 1997) on Form S-3 (the
"Registration Statement"), and the prospectus included therein (the
"Prospectus"), relating to the proposed issuance from time to time of debt
securities ("Debt Securities") in one or more series in an aggregate principal
amount of up to $500,000,000 (or (i) its equivalent (based on the applicable
exchange rate at the time of issue), if Debt Securities are issued with
principal amounts denominated in one or more foreign or composite currencies or
currency units as shall be designated by the Company, or (ii) such greater
amount, if Debt Securities are issued at an original issue discount, as shall
result in aggregate proceeds of U.S. $500,000,000 to the Company) under an
Indenture, dated as of September 22, 1997 (together with any supplements or
amendments thereto, the "Indenture"), from the Company to The Chase

Manhattan Bank, as trustee (together with any successor or additional trustee
named under the Indenture, the "Trustee").

            In so acting, we have examined and relied upon the originals, or
copies certified or otherwise identified to our satisfaction, of such records,
documents and other instruments as in our judgment are necessary or appropriate
to enable us to render the opinion expressed below.

            Based upon the foregoing, we are of the following opinion:

            1. The Company is validly existing as a corporation in good standing
      under the laws of the State of New York.

            2. When (a) the Indenture shall have been duly executed and
      delivered by the Company and the Trustee, (b) the issuance, execution and
      delivery by the Company of any of the Debt Securities shall have been duly
      authorized by all necessary corporate action of the Company and (c) such
      Debt Securities shall have been duly executed and delivered by the
      Company, authenticated by the Trustee and sold as contemplated by each of
      the Registration Statement, the Prospectus, the supplement or supplements
      to the Prospectus relating to such Debt Securities and the Indenture,
      assuming that the terms of such Debt Securities are in compliance with
      then applicable law, such Debt Securities will be validly issued and will
      constitute valid and binding obligations of the Company enforceable
      against the Company in accordance with their terms, except as may be
      limited by applicable bankruptcy, insolvency, reorganization, moratorium
      or other similar laws affecting the rights of creditors generally and by
      general principles of equity.

            Our opinion expressed above is limited to the federal laws of the
United States of America and the laws of the State of New York.

            We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name under the heading "Legal
Matters" in the Prospectus. In giving such consent, we do not thereby concede
that we are within the

Rules and Regulations of the Commission thereunder.

                                                    Very truly yours,
