                                  THE COMPANY
 
     The Company is one of the world's largest independent oil and gas
exploration and production companies with 601 million energy equivalent barrels
of proved reserves as of December 31, 1996.
 
     The Company's reserve mix has shifted dramatically in recent years,
primarily due to major crude oil discoveries both in Algeria and the U.S., which
have resulted in a larger and more balanced portfolio of energy reserves. As of
year-end 1996, crude oil, condensate and natural gas liquids reserves accounted
for 50 percent of the Company's total reserves compared to just six percent at
year-end 1986.
 
     About 80 percent of the Company's proved reserves are located in the U.S.,
primarily in the mid-continent (Kansas, Oklahoma and Texas) area, offshore in
the Gulf of Mexico and in Alaska. Currently, all of the Company's production is
in the U.S. The Company also owns interests in 13 gas gathering systems and four
gas processing plants in the U.S.
 
     Internationally, the Company is exploring for and developing crude oil
reserves in Algeria's Sahara Desert. As of December 31, 1996, the Company has
recorded 124.3 million barrels of proved crude oil and condensate reserves in
Algeria, which accounts for about 20 percent of Anadarko's total proved
reserves. Development operations are now underway. The Company is also
participating in other exploration projects in Eritrea, Jordan and Peru.
 
     The Company's executive offices are located at 17001 Northchase Drive,
Houston, Texas 77060-2141, where the telephone number is (281) 875-1101.
 
                                USE OF PROCEEDS
 
     Except as otherwise described in the Prospectus Supplement relating to an
offering of Securities, the net proceeds from the sale of the Securities will be
used for general corporate purposes, including the refinancing of outstanding
indebtedness and the financing of capital expenditures. Any specific allocation
of the net proceeds of an offering of Securities to a specific purpose will be
determined at the time of such offering and will be described in the related
Prospectus Supplement.
 
 RATIO OF EARNINGS TO FIXED CHARGES AND EARNINGS TO COMBINED FIXED CHARGES AND
                           PREFERRED STOCK DIVIDENDS
 
     The following table sets forth the Company's consolidated ratio of earnings
to fixed charges for the periods shown.

</TABLE>
 
     The ratios of earnings to fixed charges were computed by dividing earnings
by fixed charges. For this purpose, earnings include income before income taxes
and fixed charges. Fixed charges include interest and amortization of debt
expenses, and the estimated interest component of rentals.
 
     No shares of Preferred Stock were outstanding during any of the periods
presented. Accordingly, the ratio of earnings to fixed charges and preferred
stock dividends for each of the periods presented is the same as the ratio of
earnings to fixed charges.

                         DESCRIPTION OF DEBT SECURITIES
 
     The following description sets forth certain general terms and provisions
of the Debt Securities to which any Prospectus Supplement may relate. The
particular terms of the Debt Securities offered by any Prospectus Supplement and
the extent, if any, to which such general provisions may apply to the Debt
Securities so offered will be described in the Prospectus Supplement relating to
such Debt Securities.
 
     The Debt Securities will be unsecured obligations of the Company. The
Senior Debt Securities are to be issued under the Indenture (the "Senior
Indenture") to be entered into by and between the Company and Harris Trust and
Savings Bank (the "Senior Trustee") and will rank on a parity with all other
unsecured and unsubordinated indebtedness of the Company. The Subordinated Debt
Securities are to be issued under the Indenture (the "Subordinated Indenture")
to be entered into by and between the Company and First Chicago NBD (the
"Subordinated Trustee").
 
     The Senior Indenture and the Subordinated Indenture are sometimes
hereinafter collectively referred to as the "Indentures." The Senior Trustee and
the Subordinated Trustee are sometimes hereinafter collectively referred to as
the "Trustees." References set forth in the following description of Debt
Securities are to sections of both Indentures unless otherwise indicated.
 
     The terms of the Debt Securities include those stated in the applicable
Indentures and those made part of such Indentures by reference to the Trust
Indenture Act of 1939, as amended. The Debt Securities are subject to all such
terms, and prospective purchasers of Debt Securities are referred to the
applicable Indentures and the Trust Indenture Act for a statement of those
terms. The statements under this caption relating to the Debt Securities and the
Indentures are summaries and do not purport to be complete. Such summaries use
certain terms which are defined in the Indentures and are qualified in their
entirety by express reference to the Indentures which have been filed as
exhibits to the Registration Statement of which this Prospectus is a part.
 
GENERAL PROVISIONS APPLICABLE TO BOTH INDENTURES
 
     The Indentures do not limit the aggregate principal amount of debentures,
notes or other evidences of indebtedness which may be issued thereunder and
provide that Debt Securities may be issued thereunder from time to time in one
or more series.
 
     Reference is made to the Prospectus Supplement relating to the particular
series of Debt Securities offered thereby (the "Offered Debt Securities") for
the following terms of the Offered Debt Securities: (1) the title of the Offered
Debt Securities; (2) any limit on the aggregate principal amount of the Offered
Debt Securities; (3) the date or dates on which the Offered Debt Securities will
mature; (4) the rate or rates (which may be fixed or variable) per annum at
which the Offered Debt Securities will bear interest, if any, and the date from
which such interest will accrue; (5) the dates on which any such interest will
be payable and the Regular Record Dates for such Interest Payment Dates; (6) any
mandatory or optional sinking fund or purchase fund or analogous provisions; (7)
if applicable, the date after which and the price or prices at which the Offered
Debt Securities may, pursuant to any optional or mandatory redemption
provisions, be redeemed at the option of the Company or of the Holder thereof
and the other detailed terms and provisions of such optional or mandatory
redemption; (8) if applicable, any terms by which the Subordinated Securities
may be convertible into Common Stock; (9) any restrictive covenants included for
the benefit of Holders of the Offered Debt Securities; (10) any additional
Events of Default provided with respect to the Offered Debt Securities; (11) the
currency of payment of the principal of, premium, if any, and interest on the
Offered Debt Securities; (12) any index used to determine the amount of payments
of the principal of, premium, if any, and interest on the Offered Debt
Securities; (13) whether the Offered Debt Securities are to be issued in whole
or part in the form of a Global Note or Notes and, if so, the identity of the
Depositary for such Global Note or Notes; (14) the terms and conditions, if any,
upon which a Global Note or Notes may be exchanged in whole or in part for other
definitive Offered Debt Securities; and (15) any other terms of the Offered Debt
Securities. (Section 301)

<PAGE>   7
 
     Unless otherwise indicated in the Prospectus Supplement relating thereto,
the principal of, premium, if any, and interest on the Offered Debt Securities
will be payable, and the Offered Debt Securities will be exchangeable and
transfers thereof will be registrable, at the applicable Corporate Trust Offices
of the Trustees, provided that at the option of the Company, payment of any
interest may be made by check mailed to the address of the Person entitled
thereto as it appears in the Security Register. (Sections 202, 305 and 1002)
 
     The Prospectus Supplement relating to a series of Offered Debt Securities
will specify the currency or currencies in which the principal and interest are
to be paid, the denomination of the Offered Debt Securities and whether Global
Notes are to be issued. (Section 302) Special provisions relating to a series of
Offered Debt Securities denominated in or payable by reference to a currency
other than U.S. dollars, and any applicable currency exchange and tax
information, will be described in the Prospectus Supplement relating to such
series. No service charge will be made for any registration of transfer or
exchange of the Offered Debt Securities, but the Company may require payment of
a sum sufficient to cover any tax or other governmental charge payable in
connection therewith. (Section 305)
 
     Debt Securities may be issued under the Indentures as Original Issue
Discount Securities to be offered and sold at a substantial discount from the
stated principal amount. Special federal income tax, accounting and other
considerations applicable to any such Original Issue Discount Securities will be
described in the Prospectus Supplement relating thereto.
 
     Unless otherwise specified in the Prospectus Supplement relating to a
particular series of Offered Debt Securities, the covenants applicable to the
Debt Securities would not necessarily afford holders protection in the event of
a highly leveraged or other transaction involving the Company or in the event of
a material adverse change in the Company's financial condition or results of
operations.
 
  Global Notes
 
     The Debt Securities of a series may be issued in whole or in part in the
form of one or more Global Notes that will be deposited with, or on behalf of, a
depositary (the "Depositary") identified in the Prospectus Supplement relating
to such series. The specific terms of the depositary arrangement with respect to
any Debt Securities of a series will be described in the Prospectus Supplement
relating to such series. The Company anticipates that the following provisions
will apply to all depositary arrangements.
 
     Upon the issuance of a Global Note, the Depositary for such Global Note
will credit, on its book-entry registration and transfer system, the respective
principal amounts of the Debt Securities represented by such Global Note to the
accounts of institutions that have accounts with such Depositary (the
"participants"). The accounts to be credited shall be designated by the
underwriters or agents of such Debt Securities, or by the Company if such Debt
Securities are offered and sold directly by the Company. Ownership of beneficial
interests in a Global Note will be limited to participants or persons that may
hold interests through participants. Ownership of beneficial interests in such
Global Note will be shown on, and the transfer of that ownership will be
effected only through, records maintained by the Depositary for such Global Note
(with respect to interests of participants) or by participants or persons that
hold through participants (with respect to interests of persons other than
participants). The laws of some states require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to transfer beneficial interests in
a Global Note.
 
     So long as the Depositary for a Global Note, or its nominee, is the owner
of such Global Note, 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 Global Note for all purposes under the Senior Indenture. Except as set
forth below, owners of beneficial interests in a Global Note will not be
entitled to have Debt Securities of the series represented by such Global Notes
registered in their names, will not receive or be entitled to receive physical
delivery of Debt Securities of such series in definitive form and will not
 
                                        6
<PAGE>   8
 
be considered the owners or holders thereof under the Senior Indenture.
Accordingly, each person owning a beneficial interest in a Global Note 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 Senior Indenture. The Senior
Indenture provides that the Depositary may grant proxies and otherwise authorize
participants to take any action which a Holder is entitled to take under the
Senior Indenture. The Company understands that under existing industry practice,
in the event that the Company requests any action of Holders or a beneficial
owner desires to take any action a Holder is entitled to take, the Depositary
would authorize the participants to take such action and that the participants
would take such action or would otherwise act upon the instructions of
beneficial owners owning through them.
 
     Payment of principal, premium, if any, and interest on Debt Securities
registered in the name of or held by a Depositary or its nominee will be made to
the Depositary or its nominee, as the case may be, as the registered owner or
the holder of the Global Note representing such Debt Securities. None of the
Company, the Trustee, any Paying Agent or the Security Registrar for such Debt
Securities will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests in a Global Note for such Debt Securities or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.
 
     The Company expects that the Depositary for Debt Securities of a series,
upon receipt of any payment of principal, premium or interest in respect of a
Global Note, will credit immediately participants' accounts with payments in
amounts proportionate to their respective beneficial interests in the principal
amount of such Global Note as shown on the records of such Depositary. The
Company also expects that payments by participants to owners of beneficial
interests in such Global Note held through such participants will be governed by
standing instructions and customary practices, as is now the case with
securities held for the accounts of customers in bearer form or registered in
"street name", and will be the responsibility of such participants.
 
     A Global Note may not be transferred except as a whole by the Depositary
for such Global Note to a nominee of such Depositary or by a nominee of such
Depositary to such Depositary or another nominee of such Depositary. A Global
Note is exchangeable for Debt Securities registered in the names of persons
other than the Depositary with respect to such Global Note or its nominee only
if (x) such Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for such Global Note or if at any time such Depositary
ceases to be a clearing agency registered under the Exchange Act, (y) the
Company executes and delivers to the Trustee a Company Order that all such
Global Notes shall be exchangeable or (z) there shall have occurred and be
continuing an Event of Default or an event which, with the giving of notice or
lapse of time, or both, would constitute an Event of Default with respect to the
Debt Securities. Any Global Note that is exchangeable pursuant to the preceding
sentence shall be exchangeable for Debt Securities registered in such names as
the Depositary with respect to such Global Note shall direct. (Section 305).
 
  Events of Default
 
     The following are Events of Default under each Indenture with respect to
Debt Securities of any series issued thereunder: (a) failure to pay any interest
on any Debt Security of that series when due, continued for 60 days; (b) failure
to pay the principal of (or premium, if any, on) any Debt Security of that
series when due; (c) failure to make sinking fund payments in respect of any
Debt Security of that series when due, continued for 60 days; (d) failure to
perform any other covenant of the Company in the applicable Indenture (other
than a covenant included in such Indenture solely for the benefit of a series of
Debt Securities other than that series), continued for 90 days after written
notice as provided in such Indenture; (e) default by the Company in payment of
any principal of any Funded Debt outstanding in an aggregate principal amount in
excess of $10,000,000 causing such Funded Debt to become, or to be declared, due
prior to its stated maturity and such acceleration is not cured within 30 days
after notice; (f) certain events in bankruptcy, insolvency or reorganization;
and (g) any other Event of Default provided with respect to Debt Securities of
that series. (Section 501) If an Event of
 
                                        7
<PAGE>   9
 
Default provided with respect to Debt Securities of any series at the time
Outstanding shall occur and be continuing, either the applicable Trustee or the
Holders of at least 25% in principal amount of the Outstanding Debt Securities
of that series may declare the principal amount (or, if the Debt Securities of
that series are Original Issue Discount Securities, such portion of the
principal amount as may be specified in the terms of that series) of all Debt
Securities of that series to be due and payable immediately. However, any time
after a declaration of acceleration with respect to Debt Securities of any
series has been made, but before judgment or decree based on such acceleration
has been obtained, the Holders of a majority in principal amount of Outstanding
Debt Securities of that series may, under certain circumstances, rescind and
annul such acceleration. (Section 502) For information as to waiver of defaults,
see "Modification and Waiver".
 
     Reference is made to the Prospectus Supplement relating to any series of
Offered Debt Securities which are Original Issue Discount Securities for the
particular provision relating to acceleration of the Maturity of a portion of
the principal amount of such Original Issue Discount Securities upon the
occurrence of an Event of Default and the continuation thereof.
 
     Each of the Indentures provides that, subject to the duties of the
applicable Trustee to act with the required standard of care if an Event of
Default shall occur and be continuing, such Trustee will be under no obligation
to exercise any of its rights or powers under the Indenture at the request or
direction of any of the Holders, unless such Holders shall have offered to such
Trustee reasonable security or indemnity. (Section 603) Subject to such
provisions for security or indemnification of the applicable Trustee, the
Holders of a majority in principal amount of the Outstanding Debt Securities of
any series will have the right to direct the time, method and place of
conducting any proceeding for any remedy available to such Trustee or exercising
any trust or power conferred on such Trustee with respect to the Debt Securities
of that series. (Section 512)
 
     The Company will be required to furnish to each Trustee annually a
statement as to any defaults in the performance of its obligations under the
applicable Indenture. (Section 1006)
 
  Consolidation, Merger and Sale of Assets
 
     The Company, without the consent of any Holders of Outstanding Debt
Securities, may consolidate with or merge into any other person, or convey,
transfer or lease its assets substantially as an entirety to, any Person,
provided that the person formed by such consolidation or into which the Company
is merged or the Person, which acquires by conveyance or transfer or leases the
assets of the Company substantially as an entirety, is organized under the laws
of any United States jurisdiction and assumes the Company's obligations on the
Debt Securities and under the Indentures, that after giving effect to the
transaction, no Event of Default, and no event which, after notice or lapse of
time or both, would become an Event of Default, shall have happened and be
continuing, and that certain other conditions are met. (Article Eight)
 
  Modification and Waiver
 
     Modification and amendments of each Indenture may be made by the Company
and the applicable Trustee with the consent of the Holders of a majority in
principal amount of the Outstanding Debt Securities of each series affected
thereby; provided, however, that no such modification or amendment may, without
the consent of the Holder of each Outstanding Debt Security affected thereby:
(a) change the Stated Maturity of the principal of, or any installment of
principal of or interest on, any Debt Security; (b) reduce the principal amount
of, or any premium or interest on, any Debt Security; (c) reduce the amount of
principal of an Original Issue Discount Security payable upon acceleration of
the Maturity thereof; (d) change the place or currency of payment of principal
of, or premium (if any) or interest on, any Debt Security; (e) impair the right
to institute suit for the enforcement of any payment on or with respect to any
Debt Security; or (f) reduce the percentage in principal amount of Outstanding
Debt Securities of any series, the consent of the Holders of which is
 
                                        8
<PAGE>   10
 
required for modification or amendment of the applicable Indenture or for waiver
of compliance with certain provisions of the applicable Indenture or for waiver
of certain defaults. (Section 902)
 
     Without the consent of any Holder of Outstanding Debt Securities, the
Company may amend or supplement each of the Indentures and each series of Debt
Securities to cure any ambiguity or inconsistency or to provide for Debt
Securities in bearer form in addition to or in place of registered Debt
Securities or to make any other provisions that do not adversely affect the
rights of any Holder of Outstanding Debt Securities. (Section 901)
 
     The Holders of a majority in principal amount of the Outstanding Debt
Securities of any series may on behalf of the Holders of all Debt Securities of
that series waive any past default under the Indenture with respect to that
series, except a default in the payment of the principal of (or premium, if any)
or interest on any Debt Security of that series or in respect of a provision
which under the Indenture cannot be modified or amended without the consent of
the Holder of each Outstanding Debt Security of that series affected. (Section
513)
 
  Defeasance
 
     The Indentures provide that the Company may elect to defease and be
discharged from any and all obligations with respect to such Debt Securities
(except for the obligations to register the transfer or exchange of such Debt
Securities, to replace temporary or mutilated, destroyed, lost or stolen Debt
Securities, to maintain an office or agency in respect of the Debt Securities
and to hold moneys for payment in trust) ("defeasance"), upon the deposit with
the applicable Trustee (or other qualifying trustee), in trust for such purpose,
of money, and/or U.S. Government Obligations (as defined), which through the
payment of principal and interest in accordance with their terms will provide
money, in an amount sufficient to pay the principal of (and premium, if any) and
interest on such Debt Securities, and any mandatory sinking fund or analogous
payments thereon, on the scheduled due dates therefor. (Article Thirteen)
 
     In the event of a defeasance as provided above with respect to any Debt
Securities, holders of such Debt Securities would be able to look only to the
trust fund established for payments of principal of (and premium, if any) and
interest on such Debt Securities until maturity. Further, under current federal
income tax laws, such a defeasance could be a taxable exchange of such Debt
Securities for interests in the trust. As a consequence, a holder may recognize
gain or loss equal to the difference between the holder's cost or other tax
basis for such Debt Securities and the value of the holder's interest in the
trust, and thereafter may be required to include in income a share of the
income, gain and loss of the trust.
 
SENIOR INDENTURE PROVISIONS
 
  Limitation on Liens
 
     The Senior Indenture provides that if the Company or any Restricted
Subsidiary shall incur, assume or guarantee any Debt secured by a Mortgage on
any Principal Property, on any shares of stock of any Restricted Subsidiary or
on any Restricted Subsidiary Indebtedness, the Company will secure, or cause
such Restricted Subsidiary to secure, the Senior Securities equally and ratably
with (or prior to) such secured Debt, unless after giving effect thereto the
aggregate amount of all such Debt so secured would not exceed 10% of the
Consolidated Net Tangible Assets of the Company and its Restricted Subsidiaries.
This restriction will not apply to, and there shall be excluded in computing
secured Debt for the purpose of such restriction, Debt secured by (a) Mortgages
existing at the date of the Senior Indenture, (b) Mortgages on property, on
shares of stock or Restricted Subsidiary Indebtedness of any corporation
existing at the time such corporation becomes a Restricted Subsidiary, (c)
Mortgages in favor of the Company or any Restricted Subsidiary, (d) Mortgages on
property, shares of stock, or Restricted Subsidiary Indebtedness existing at the
time of acquisition thereof (including acquisition through merger, consolidation
or other reorganization) and certain purchase money Mortgages and construction
cost Mortgages, (e) certain Mortgages in favor of governmental
 
                                        9
<PAGE>   11
 
bodies (including Mortgages in connection with tax-exempt indebtedness), (f)
certain Mortgages to secure partial, progress, advance or other payments or any
Debt incurred to finance the purchase price or cost of construction, development
or repair, alteration or improvement of property, (g) Mortgages on oil, gas,
coal or other minerals in place or on geothermal resources in place and related
interests incurred to finance production, development or acquisition costs, (h)
Mortgages on certain equipment, (i) Mortgages arising in connection with certain
government contracts and (j) certain extensions, renewals or replacements of any
Debt secured by any Mortgage referred to in the foregoing clauses (a) through
(i), inclusive. (Section 1005) The Senior Indenture will not restrict the
incurrence of unsecured Debt by the Company or its Subsidiaries.
 
  Certain Summary Definitions
 
     "Consolidated Net Tangible Assets" means the aggregate amount of assets of
the Company and its Restricted Subsidiaries after deducting (a) all current
liabilities (excluding any Funded Debt) and (b) all goodwill, trade names and
trademarks, patents, unamortized debt discount and expense and other like
intangibles.
 
     "Principal Property" means any plant or real property interest located in
the United States or offshore the United States owned by the Company or any
Restricted Subsidiary, the gross book value of which exceeds 2% of Consolidated
Net Tangible Assets, unless the Board of Directors determines such property is
not of material importance to the total business of the Company. As of March 31,
1997, approximately 15% of Consolidated Net Tangible Assets would be within the
definition of Principal Properties.
 
     "Restricted Subsidiary" means a subsidiary of the Company except a
subsidiary (a) which neither transacts any substantial portion of its business
nor regularly maintains any substantial portion of its fixed assets within the
United States or offshore the United States or (b) which is engaged primarily in
financing the operations of the Company or its Subsidiaries, or both.
 
  Regarding the Senior Trustee
 
     The Senior Trustee is an affiliate of the Bank of Montreal ("BOM"). The
Company has a $225,000,000 Revolving Credit Agreement and a $125,000,000 364-Day
Credit Agreement with a group of commercial banks, including BOM. Pursuant to
the terms of the Agreements, BOM has a commitment to loan the Company an
aggregate of $40,000,000.
 
SUBORDINATED INDENTURE PROVISIONS
 
  Conversion Rights
 
     The Prospectus Supplement will provide whether the Offered Debt Securities
will consist of convertible Subordinated Securities and, if so, the initial
conversion price per share at which such convertible Subordinated Securities
will be convertible into Common Stock. Subject to prior redemption of the
convertible Subordinated Securities, the holders of such Securities will be
entitled at any time on or before the close of business on the maturity date
thereof to convert such Securities (or, in the case of convertible Subordinated
Securities of denominations in excess of $1,000 any portion of which is $1,000
or an integral multiple of $1,000) into shares of Common Stock at the initial
conversion price set forth in the Prospectus Supplement. No adjustment will be
made on conversion of any convertible Subordinated Securities for interest
accrued thereon or, except as set forth below, for dividends on any securities
issued upon such conversion. Certificates for shares of Common Stock issued, on
or prior to the Expiration Date, hereinafter referred to, or Distribution Date,
as defined below under "Rights Agreement", upon conversion of convertible
Subordinated Securities shall also evidence one right (a "Right"), in respect of
each such share, pursuant to the Rights Agreement, dated as of October 4, 1988
(the "Rights Agreement") between the Company and Chemical Bank, as then in
effect. See "Description of Capital Stock, Rights Agreement and Restated
Certificate of Incorporation -- Rights Agreement" for a description of the
Rights and the Rights Agreement. "Expiration Date" means the earlier of (i)
October 20, 1998 or (ii) the redemption of the Rights.
 
                                       10
<PAGE>   12
 
     In order to exercise the right of conversion, the Holder of any such
convertible Subordinated Securities must surrender his convertible Subordinated
Securities to the Company at any office or agency of the Company maintained for
such purpose. The convertible Subordinated Securities to be surrendered must be
accompanied by written notice to the Company that the Holder elects to convert
such Securities.
 
     If any convertible Subordinated Security, whether or not called for
redemption, is converted between a record date for the payment of interest and
the next succeeding interest payment date, such Security must be accompanied by
funds payable to the Company equal to the interest payable to the registered
holder on such interest payment date on the principal amount so converted. In
the case of any convertible Subordinated Security or portion thereof called for
redemption, conversion rights expire at the close of business on the Redemption
Date, even if such redemption occurs at a time when conversion of the
Subordinated Security portion thereof is in the best interests of the Holder.
(Sections 1501, 1502 and 1503)
 
     Except where Subordinated Securities surrendered for conversion must be
accompanied by such payment, no interest on converted Subordinated Securities
will be payable by the Company on any interest payment date subsequent to the
date of conversion.
 
     No fractional shares of Common Stock will be issued upon conversion but, in
lieu thereof, an adjustment in cash will be made based on the market price at
the close of business on the date of conversion. (Section 1503)
 
     The Conversion Price will be subject to adjustment in the event of: (i) the
payment of certain stock dividends on the Common Stock; (ii) the issuance of
certain rights or warrants to all holders of the Common Stock entitling them to
subscribe for or purchase Common Stock at a price less than the market price;
(iii) the subdivision of Common Stock into a greater number of shares of Common
Stock; (iv) the distribution by the Company to all holders of the Common Stock
of evidences of indebtedness or assets of the Company (excluding rights or
warrants and any dividends or distributions mentioned above); and (v) the
reclassification of Common Stock into other securities. (Section 1504) In case
of any consolidation or merger of the Company with or into any other corporation
(other than a consolidation or merger which does not result in any
reclassification, change or conversion of Common Stock), or in case of any sale
or transfer of substantially all the assets of the Company, any Holder of any
Subordinated Securities will be entitled, after the occurrence of any such
event, to receive on conversion the kind and amount of shares of capital stock
and other securities, cash or other property receivable upon such event by a
holder of the number of shares of Common Stock into which such Securities might
have been converted immediately prior to the occurrence of the event. (Section
1511) In addition to the foregoing adjustments, the Company will be permitted to
make such decreases in the Conversion Price as it considers to be necessary in
order that any event treated for federal income tax purposes as a dividend of
stock or stock rights will not be taxable to the holders of Common Stock.
(Section 1504) No adjustment for dividends other than certain stock dividends on
the Common Stock is to be made upon conversion. (Section 1502)
 
  Subordination
 
     The payment of the principal of (and premium, if any) and interest on the
Subordinated Securities is expressly subordinated, to the extent and in the
manner set forth in the Subordinated Indenture, in right of payment to the prior
payment in full of all present and future Senior Indebtedness of the Company.
(Section 1401) In the event of any insolvency or bankruptcy case or proceeding
or any receivership, liquidation, dissolution or other winding up of the
Company, the holders of Senior Indebtedness shall be entitled to receive payment
in full of all amounts due or to become due on or in respect of all Senior
Indebtedness before the Holders of the Subordinated Securities are entitled to
receive any payment on the Subordinated Securities (subject to the power of a
court of competent jurisdiction to make other equitable provision in a lawful
plan of reorganization under applicable bankruptcy laws), except that in any
such case or proceeding the Holders of the
 
                                       11
<PAGE>   13
 
Subordinated Securities may be entitled to receive securities of the Company
which are subordinate and subject to the prior payment in full of all Senior
Indebtedness then outstanding. In the event that the Subordinated Securities are
declared due and payable before their stated maturity because of the occurrence
of an Event of Default, the holders of Senior Indebtedness then outstanding
shall be entitled to receive payment in full of all amounts due or to become due
on or in respect of all Senior Indebtedness before the Holders of the
Subordinated Securities are entitled to receive any payment on account of the
Subordinated Securities. During the continuation of any default in the payment
of principal of (or premium, if any) or interest on any Senior Indebtedness
beyond any applicable period of grace, unless and until such default in payment
shall have been cured or waived or shall have ceased to exist, or in the event
any judicial proceeding shall be pending with respect to any such default, no
payments may be made on the Subordinated Securities by the Company. (Article
Fourteen) By reason of such subordination, in the event of insolvency or other
specified eventualities, the Holders of the Subordinated Securities may recover
less, ratably, and the holders of Senior Indebtedness may recover more, ratably,
than other creditors of the Company.
 
     "Senior Indebtedness" means principal of (and premium, if any) and unpaid
interest on (a) indebtedness (secured or unsecured) incurred, assumed or
guaranteed, directly or indirectly, by the Company either before, on or after
the date of the Subordinated Indenture and which is for money borrowed
(including any obligation to pay or reimburse any bank in respect of letter of
credit drawings, payment of drafts or similar transactions), or which is
evidenced by notes, debentures, bonds or other similar securities whether or not
for money borrowed and (b) renewals, extensions or refundings of any such
indebtedness, unless it is provided by the instrument creating, evidencing,
renewing, extending or refunding the same or pursuant to which the same is
outstanding, that such indebtedness is not senior in right of payment to the
Subordinated Securities. (Section 101)
 
     As of July 3, 1997, the Company had $809,200,000 aggregate principal amount
of Senior Indebtedness outstanding. The Subordinated Indenture does not restrict
the amount of additional Senior Indebtedness which may be incurred by the
Company.
 
  Regarding the Subordinated Trustee
 
     The Company has a $225,000,000 Revolving Credit Agreement and a
$125,000,000 364-Day Credit Agreement with a group of commercial banks,
including the Subordinated Trustee. Pursuant to the terms of the Agreements, the
Subordinated Trustee has a commitment to loan the Company an aggregate of
$40,000,000.

               DESCRIPTION OF CAPITAL STOCK, RIGHTS AGREEMENT AND
                     RESTATED CERTIFICATE OF INCORPORATION
 
     The following summaries of the Company's Preferred Stock, Common Stock and
the Rights Agreement are qualified in their entirety by reference to the
Restated Certificate of Incorporation of the Company and the Rights Agreement.
The Restated Certificate of Incorporation and the Rights Agreement are filed as
exhibits to the Registration Statement of which this Prospectus is a part.
 
GENERAL
 
     Under the Company's Restated Certificate of Incorporation, the Company is
authorized to issue (i) 200,000,000 shares of Common Stock, of which 60,618,034
shares were issued and outstanding at March 31, 1997 and (ii) 2,000,000 shares
of Preferred Stock, none of which are issued and outstanding as of the date of
this Prospectus.
 
COMMON STOCK
 
     Holders of the Common Stock are entitled to one vote per share on all
matters to be voted on by stockholders and are entitled, subject to any
preferential rights of holders of preferred stock, to receive such dividends, if
any, as may be declared from time to time by the Board in its discretion out of
funds legally available therefor. Upon any liquidation or dissolution of the
Company, the holders of the Common Stock are entitled, subject to any
preferential rights of holders of preferred stock, to receive pro rata all
assets remaining available for distribution to stockholders after payment of all
liabilities. The Common Stock has no preemptive or other subscriptive rights,
and there are no conversion rights or redemption or sinking fund provisions with
respect to the Common Stock. The vote of the holders of a majority of the Common
Stock is required for any action by the stockholders of the Company, except as
described under "Restated Certificate of Incorporation" below. The Company's
board of directors is divided into three classes of directors serving staggered
three-year terms. Class I has three directors and Class II and Class III each
have two directors. The Company's Common Stock is listed on the New York Stock
Exchange under the symbol "APC".
 
PREFERRED STOCK
 
     The Board, without further action by the stockholders, is authorized to
issue shares of preferred stock in one or more series, and to determine
preference as to dividends and in liquidation and voting, conversion, redemption
and other rights more favorable with respect to dividends and liquidation than
those of the holders of the Common Stock. The particular rights, preferences and
privileges of any series of Preferred Stock will be set forth in the Prospectus
Supplement. Such preferences and rights as may be established could have the
effect of impeding the acquisition of control of the Company. No such Preferred
Stock is outstanding as of the date of this Prospectus. Pursuant to the Rights
Agreement the Board has designated the Series A Junior Participating Preferred
Stock. If so specified in the Prospectus Supplement, the Preferred Stock may be
represented by Depositary Shares entitling the holder proportionally to all
rights and preferences of the Preferred Stock.
 
RIGHTS AGREEMENT
 
     On October 4, 1988, the Board of Directors of the Company adopted the
Rights Agreement and declared a dividend of one Right for each outstanding share
of Common Stock. At the same time, the Board of Directors of the Company
redeemed rights which had been issued pursuant to the rights agreement adopted
on September 10, 1986.
 
     Pursuant to the Rights Agreement, the Company will have outstanding one
Right for each share of Common Stock which is issued and outstanding prior to
the date the Rights become exercisable. Until the Rights become exercisable,
they will be evidenced by certificates for shares of Common Stock and will
automatically trade with such stock. If and when the Rights become exercisable,
Rights certificates will be distributed and the Rights will become separately
transferable.
 
                                       13
<PAGE>   15
 
     Each Right will entitle the registered holder to purchase from the Company
one two-hundredth of a share (a "Unit") of Series A Junior Participating
Preferred Stock of the Company, at a price of $80.00 per Unit (the "Purchase
Price"), subject to adjustment. In general, the Rights become exercisable (and
transferable apart from the Common Stock) on the earlier of (i) ten days
following a public announcement that a person or group (an "Acquiring Person")
has acquired beneficial ownership of 20% or more of the Common Stock (the "Stock
Acquisition Date"), (ii) ten business days following the commencement of an
offer to acquire beneficial ownership of 25% or more of the Common Stock or
(iii) ten days after a person has acquired at least 15% of the Common Stock and
the Company's Board of Directors determines that (x) beneficial ownership by
such person of such shares is intended to cause the Company to repurchase the
Common Stock owned by such person or to pressure the Company into taking action
intended to provide such person with short-term financial gains under
circumstances where the best long-term interests of the Company and its
stockholders would not be served or (y) such person's beneficial ownership of
the Company's Common Stock is causing or reasonably likely to cause a material
adverse impact on the business or prospects of the Company (any such person
being referred to herein as an "Adverse Person"). The date on which the Rights
become exercisable is referred to as the "Distribution Date".
 
     In the event that (i) a Person becomes the beneficial owner of 25% or more
of the then outstanding shares of Common Stock (except pursuant to an offer for
all outstanding shares of Common Stock which a majority of the independent
directors on the Board of Directors determines to be fair to and otherwise in
the best interest of the Company and its stockholders), or (ii) the Board of
Directors determines that a person is an Adverse Person, each holder of a Right
will thereafter have the right to receive, upon exercise, Common Stock (or other
consideration) having a value equal to two times the Purchase Price.
Notwithstanding any of the foregoing, following the occurrence of any of the
events set forth in this paragraph, all Rights that are, or (under certain
circumstances specified in the Rights Agreement) were beneficially owned by any
Acquiring Person or Adverse Person will be null and void. However, Rights are
not exercisable following the occurrence of either of the events set forth above
until such time as the Rights are no longer redeemable by the Company.
 
     In general, in the event that, following the Stock Acquisition Date, (i)
the Company shall consolidate with, or merge with and into, any other Person
(other than a Subsidiary of the Company), and the Company shall not be the
continuing or surviving corporation of such consolidation or merger, (ii) any
Person (other than a Subsidiary of the Company) shall consolidate with, or merge
with or into, the Company, and the Company shall be the continuing or surviving
corporation of such consolidation or merger and, in connection with such
consolidation or merger, all or part of the outstanding shares of Common Stock
shall be changed into or exchanged for stock or other securities of any other
Person or cash or any other property, or (iii) the Company shall sell or
otherwise transfer (or one or more of its Subsidiaries shall sell or otherwise
transfer), in one transaction or a series of related transactions, assets or
earning power aggregating more than 50% of the assets or earning power of the
Company and its Subsidiaries (taken as a whole) to any Person or Persons each
holder of a Right (except Rights which previously have been voided as set forth
above) shall thereafter have the right to receive, upon exercise, common stock
of such Person having a value equal to two times the Purchase Price of the
Right.
 
     Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends. While the distribution of the Rights will not
be taxable to stockholders or to the Company, stockholders may, depending upon
the circumstances, recognize taxable income in the event that the Rights become
exercisable for Common Stock (or other consideration) of the Company or for
common stock of the acquiring company as set forth above.
 
     Other than those provisions relating to the principal economic terms of the
Rights, any of the provisions of the Rights Plan may be amended by the Board of
Directors of the Company prior to the Distribution Date. After the Distribution
Date, the provisions of the Rights Plan may be amended by the Board of Directors
in order to cure any ambiguity, to make changes which do not adversely affect
 
                                       14
<PAGE>   16
 
the interests of holders of Rights, or to shorten or lengthen any time period
under the Rights Plan; provided, however, that no amendment to adjust the time
period governing redemption shall be made at such time as the Rights are not
redeemable.
 
     The Rights have certain anti-takeover effects. The Rights will cause
substantial dilution to a person or group that attempts to acquire the Company
in a manner which causes the Rights to become exercisable for shares of Common
Stock at less than fair market value unless the offer is conditioned on a
substantial number of Rights being acquired. The Rights, however, should not
affect any prospective offeror willing to make an offer at a fair price and
otherwise in the best interests of the Company and its stockholders, as
determined by a majority of the Directors who are not officers of the Company
and who are not affiliated with an Acquiring Person, or willing to negotiate
with the Board of Directors. The Rights should not interfere with any merger or
other business combination approved by the Board of Directors since the Board of
Directors may, at its option, at any time until ten days following the Stock
Acquisition Date redeem all but not less than all the then outstanding Rights at
the Redemption Price.
 
     The Rights will also adversely affect a person who desires to obtain
control of the Company without acquiring 100% ownership and then to engage in
specified self-dealing transactions. The Rights will have no effect, however, on
a person who is willing to acquire control of the Company and wait until the
Rights expire, without engaging in any self-dealing transactions, before
acquiring 100% ownership. The Rights will not affect a transaction approved by
the Board of Directors of the Company prior to the acquisition by any person or
group of 20% of the Common Stock, because the Rights can be redeemed before the
consummation of such transaction.
 
     The Rights will expire at the close of business on October 20, 1998, unless
redeemed earlier by the Company. In general, the Company may redeem the Rights,
at a price of $0.01 per Right, at any time until ten days following the Stock
Acquisition Date, but Rights may not be redeemed if the Board of Directors has
previously declared a person to be an Adverse Person although the redemption
right may be reinstated under certain conditions.
 
RESTATED CERTIFICATE OF INCORPORATION
 
     The Certificate contains a "fair price" provision, the purpose of which is
to give greater assurance to the holders of the Company's capital stock that
they will receive fair and equitable treatment in the event of certain "Business
Combinations" with an "Interested Stockholder" or certain related parties (or in
which an "Interested Stockholder" or any such related party has an interest
other than proportionately as a stockholder) by requiring that the Business
Combination satisfy certain procedural safeguards, or that the transaction be
approved by the affirmative vote of not less than 80% of all of the capital
stock which by its terms may be voted on all matters submitted to the
stockholders of the Company generally ("Voting Stock").
 
     The term "Interested Stockholder" is defined to include beneficial owners
of 5% or more of the Voting Stock. The term "Business Combination" is defined to
include, among other things, (a) a merger or consolidation of the Company or any
Subsidiary or adoption of a plan of liquidation of the Company, (b) a sale,
other disposition, loan or other arrangement (or a series of such transactions)
involving assets with a Fair Market Value (as defined) of $25,000,000 or more or
constituting more than 5% of total assets or, in the case of capital stock,
stockholders' equity of the entity in question, and (c) any amendment of the
By-Laws of the Company.
 
     In addition to any affirmative stockholder vote otherwise applicable, a
Business Combination with an Interested Stockholder or certain related parties
(or in which an Interested Stockholder or any such related party has an interest
except proportionately as a stockholder) requires (1) the 80% vote
 
                                       15
<PAGE>   17
 
referred to above, (2) approval by a majority of the Continuing Directors (as
defined) or (3) satisfaction of, among others, the following requirements:
 
          (a) The consideration per share to be received in the Business
     Combination by stockholders of each class shall be in cash or in the form
     used to acquire beneficial ownership of the largest number of shares of
     such class previously acquired by the Interested Stockholder. Such
     consideration shall equal at least the highest of:
 
             (i) the highest per share price offered or paid by the Interested
        Stockholder for shares of such class within the three-year period prior
        to the date of announcement of the Business Combination or in the
        transaction in which the Interested Stockholder became such;
 
             (ii) the Fair Market Value per share of such class on the date of
        announcement of the Business Combination or the date on which the
        Interested Stockholder became such, whichever is higher; or
 
             (iii) the highest preferential amount per share (if any) to which
        holders of shares of such class are entitled in the event of a
        liquidation, dissolution or winding up of the Company;
 
          (b) After the date on which the Interested Stockholder becomes such,
     dividends shall not have been reduced (except as approved by a majority of
     the Continuing Directors) and the Interested Stockholder shall not have
     acquired additional shares of stock, except in certain limited
     circumstances; and
 
          (c) The Interested Stockholder shall not have made any major change in
     the Company's business or equity capital structure without the approval of
     a majority of the Continuing Directors.
 
     The Certificate further provides that stockholders shall be entitled to
cumulative voting at any time during which there shall be a 30% Stockholder
(defined generally to include any beneficial owner of 30% or more of the Voting
Stock).
 
     The existence of these provisions may make a merger or takeover of the
Company more difficult or discourage a merger or takeover of the Company, or the
acquisition of control of the Company, by another person or entity, and, as a
consequence, will make the removal of incumbent management more difficult.
 
                              PLAN OF DISTRIBUTION
GENERAL
 
     The Company may sell offered Securities to or through one or more
underwriters or dealers, and also may sell offered Securities directly to other
purchasers or through agents or through a combination of any such methods of
sale. Any such underwriter or agent involved in the offer and sale of the
offered Securities will be named in the Prospectus Supplement. The distribution
of the offered 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.
 
     The Company may from time to time authorize underwriters or dealers acting
as the Company's agents to offer and sell the offered Securities upon the terms
and conditions as set forth in any Prospectus Supplement. In connection with the
sale of offered Securities, underwriters or dealers may receive compensation
from the Company or from purchasers of offered Securities for whom they may act
as agents in the form of discounts, concessions or commissions. Underwriters,
dealers and agents that participate in the distribution of offered Securities
may be deemed to be underwriters, and any discounts or commissions received by
them from the Company and any profit on the resale of offered Securities by them
may be deemed to be underwriting discounts and commissions under the Securities
 
                                       16
<PAGE>   18
 
Act of 1933 (the "1933 Act"). Any such person who may be deemed to be an
underwriter will be identified, and any such compensation received from the
Company will be described, in the Prospectus Supplement.
 
     Under agreements which may be entered into by the Company, underwriters,
dealers and agents who participate in the distribution of offered Securities may
be entitled to indemnification or contribution by the Company against certain
liabilities, including liabilities under the 1933 Act, and to reimbursement by
the Company for certain expenses.
 
     Certain of the underwriters, dealers or agents may engage in transactions
with and perform services for the Company in the ordinary course of business.
 
     The specific terms and manner of sale of offered Securities are set forth
or summarized in the Prospectus Supplement.
 
DELAYED DELIVERY ARRANGEMENTS
 
     If so indicated in the Prospectus Supplement, the Company will authorize
underwriters or other persons acting as the Company's agents to solicit offers
by certain institutions to purchase Offered Debt Securities from the Company
pursuant to contracts providing for payment and delivery on a future date.
Institutions with which such contracts may be made include commercial and
savings banks, insurance companies, pension funds, investment companies,
educational and charitable institutions and others, but in all cases will be
subject to acceptance by the Company. The obligations of any purchaser under any
such contract will be subject to the condition that the purchase of Offered Debt
Securities shall not at the time of delivery be prohibited under the laws of the
jurisdiction to which such purchaser is subject. The underwriters and such other
persons will not have any responsibility in respect of the validity or
performance of such contracts.
 
                             VALIDITY OF SECURITIES
 
     The validity of the offered Securities will be passed upon for the Company
by Davis Polk & Wardwell and for any underwriters, dealers or agents by Hughes
Hubbard & Reed LLP, New York, New York.

     Section 145 of the Delaware General Corporation Law provides for
indemnification of officers and directors under certain conditions.
 
     Article IX of the By-Laws of the Company provides for indemnification of
officers and directors to the fullest extent which may be provided by a by-law

     The Company maintains insurance for officers and directors of the
Registrant against certain liabilities, including liabilities under the
Securities Act of 1933, under insurance policies, the premiums of which are paid
by the Company. The effect of these is to indemnify any officer or director of
the Registrant against expenses, judgments, attorney's fees and other amounts
paid in settlements incurred by an officer or director upon a determination that
such person acted in good faith.

ITEM 17. UNDERTAKINGS.
 
     (a) 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; 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 with or furnished
     to the Commission by the registrant 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) 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.

     (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to any charter provision, by-law, contract, arrangement,
statute, or otherwise, the registrant has been advised that in the opinion of
the Commission such indemnification is against public policy as expressed in the
Securities Act of 1933 and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted against the registrant 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 of whether such indemnification by it is against public policy as
expressed in the Securities Act of 1933 and will be governed by the final
adjudication of such issue.

representations by, counsel, unless such officer knows that the certificate or
opinion or representations with respect to the matters upon which his
certificate or opinion is based are erroneous. Any such certificate or Opinion
of Counsel may be based, insofar as it relates to factual matters, upon a
certificate or opinion of, or representations by, an officer or officers of the
Company stating that the information with respect to such factual matters is in
the possession of the Company, unless such counsel knows that the certificate or
opinion or representations with respect to such matters are erroneous.
 
     Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.
 
SECTION 104.  Acts of Holders.
 
     (a) Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by Holders may
be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Holders in person or by agent duly appointed in writing;
and, except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments are delivered to the Trustee and,
where it is hereby expressly required, to the Company. Such instrument or
instruments (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the "Act" of the Holders signing such instrument or
instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and (subject to

                                       10

Section 601) conclusive in favor of the Trustee and the Company, if made in the
manner provided in this Section.
 
     (b) The fact and date of the execution by any Person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
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 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 Securities shall be proved by the Security Register.
 
     (d) If the Company shall solicit from Holders any request, demand,
authorization, direction, notice, consent, waiver or other Act, the Company may,
at its option, by Board Resolution, fix in advance a record date (which may be
any date not less than 10 nor more than 60 days before such solicitation) for
the determination of Holders 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 the record date, but only the Holders of record at the
close of business on the record date shall be deemed to be Holders for the
purposes of determining whether Holders of the requisite proportion of the
Outstanding Securities or a series thereof 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 or a series
thereof shall be computed as of the record date.
 
     (e) Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Holder of any Security shall bind every future Holder of the
same Security and the Holder of every Security issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

SECTION 105.  Notices, Etc., to Trustee and Company.
 
     Any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with,
 
          (1) the Trustee by any Holder or by the Company shall be sufficient
     for every purpose hereunder if made, given, furnished or filed in writing
     to or with the Trustee at its Corporate Trust Office, Attention: Corporate
     Trust Administration, or
 
          (2) the Company by the Trustee or by any Holder shall be sufficient
     for every purpose hereunder (unless otherwise herein expressly provided) if
     in writing and mailed, first-class postage prepaid, to the Company
     addressed to it at the address of its principal office specified in the
     first paragraph of this instrument or sent by facsimile transmission to
     (713) 874-3264 and confirmed by voice at (713) 874-3346, in either case to
     the attention of Treasurer, or at any other address previously furnished in
     writing to the Trustee by the Company.
 
SECTION 106.  Notice to Holders; Waiver.
 
     Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice. 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. Where this Indenture provides for notice in any
manner, such notice may be waived in writing by the Person entitled to receive
such notice, either before or after the event, and such waiver shall be the
equivalent of such notice. Waivers of notice by Holders shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.
 
     In case by reason of the suspension of regular mail service or by reason of
any other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute
a sufficient notification for every purpose hereunder.

SECTION 107.  Conflict with Trust Indenture Act.

imposed by operation of Section 318(c) of the Trust Indenture Act, such imposed
duties shall control.
 
SECTION 108.  Effect of Headings and Table of Contents.

     In case any provision in this Indenture or in 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 111.  Benefits of Indenture.
 
     Nothing in this Indenture or in the Securities, express 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 112.  Governing Law.
 
     THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
 
SECTION 113.  Legal Holidays.
 
     In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the
Securities) payment of interest or principal (and premium, if any) need not be
made at such Place of Payment on such date, but may be made on the next
succeeding Business Day at such Place of Payment with the same force and effect
as if made on the Interest Payment Date or Redemption Date, or at the Stated
Maturity, provided that no interest shall accrue for the period from and after
such Interest Payment Date, Redemption Date or Stated Maturity, as the case may
be.

consent or waiver by the Holder of this Security shall be conclusive and binding
upon such Holder and upon all future Holders of this Security and of any
Security issued upon the registration of transfer hereof or in exchange herefor
or in lieu hereof, whether or not notation of such consent or waiver is made

and interest on this Security are payable, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of this series,
of authorized denominations and for the same aggregate principal amount, will be
issued to the designated transferee or transferees.
 
     The Securities of this series are issuable only in registered form without
coupons in denominations of $........ and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series of a different authorized denomination, as
requested by the Holder surrendering the same.
 
     No service charge shall be made for any such registration of trans-
fer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

have the meanings assigned to them in the Indenture.

Company Order contemplated by Section 303 for the authentication and delivery of

which are established by action taken pursuant to a Board Resolution are not
issued at one time, it shall not be necessary (notwithstanding any provision of
Section 201 or this Section) to deliver a record of or Officers' Certificate
certifying such action at the time of issuance of each Security of such series,
but an appropriate record of such action or such Officers' Certificate shall be
delivered at or prior to the time of issuance of the first Securities of such

SECTION 302.  Denominations.
 
     The Securities of each series shall be issuable in registered form without
coupons in such denominations as shall be specified as contemplated by Section
301. In the absence of any such provisions with respect to the Securities of any
series, the Securities of such series shall be issuable in denominations of
$1,000 and any integral multiple thereof.
 
SECTION 303.  Execution, Authentication, Delivery and Dating.
 
     The Securities shall be executed on behalf of the Company by its Chairman
of the Board, its President or one of its Vice Presidents, under its corporate
seal reproduced thereon attested by its Secretary or one of its Assistant
Secretaries. The signature of any of these officers on the Securities may be
manual or facsimile.
 
     Securities bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.
 
     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities 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. If all
the Securities of any series are not to be issued at one time, such Company
Order may establish procedures for completion of the forms and determination of
the terms of such Securities and authentication and delivery thereof from time
to time; such procedures may include electronic transmission of instructions as
to such completion, determination, authentication and delivery. If the forms or
terms of the Securities of the series have been established in or pursuant to
one or more Board Resolutions as permitted by Sections 201 and 301, in
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive such documents as it may reasonably request. The Trustee
shall also be entitled to receive, and (subject to Section 601) shall be fully
protected in relying upon, an Opinion of Counsel stating,
 
          (a) if the forms of such Securities has been established in or
     pursuant to a Board Resolution as permitted by Section 201, that each
 
<PAGE>   32
 
                                       24
303
 
     such form has been established or will, when established in compliance with
     the Company Order, be established in conformity with the provisions of this
     Indenture;
 
          (b) if the terms of such Securities have been established in or
     pursuant to a Board Resolution as permitted by Section 301, that such terms
     have been established or will, when established in compliance with the
     Company Order, be established in conformity with the provisions of this
     Indenture; and
 
          (c) that such Securities, 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, moratorium, reorganization
     and other laws of general applicability relating to or affecting the
     enforcement of creditors' rights, to general equity principles and to such
     other matters as shall be specified in such Opinion of Counsel.
 
Such Opinion of Counsel shall also cover such other matters as the Trustee may
reasonably request. If such form or terms have been so established, the Trustee
shall not be required to authenticate such Securities if the issue of such
Securities pursuant to this Indenture will affect the Trustee's own rights,
duties or immunities under the Securities and this Indenture or otherwise in a
manner which is not reasonably acceptable to the Trustee. If all the Securities
of any series are not to be issued at one time, it shall not be necessary to
deliver an Opinion of Counsel at the time of issuance of each Security, but an
Opinion of Counsel, with appropriate modifications, may instead be delivered at
or prior to the time of the first issuance of Securities of such series.
 
     Each Security shall be dated the date of its authentication.
 
     No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder and is entitled to the
benefits of this Indenture.

SECTION 304.  Temporary Securities.
 
     Pending the preparation of definitive Securities of any series, the Company
may execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.
 
     If temporary Securities of any series are issued, the Company will cause
definitive Securities of that series to be prepared without unreasonable delay.
After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for definitive Securities of
such series upon surrender of the temporary Securities of such series at the
office or agency of the Company in a Place of Payment for that series, without
charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities of any series the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of the same series of authorized denominations. Until so
exchanged the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.
 
SECTION 305.  Registration, Registration of Transfer and Exchange.
 
     The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby
appointed "Security Registrar" for the purpose of registering Securities and
transfers of Securities as herein provided.
 
     Upon surrender for registration of transfer of any Security of any series
at the office or agency in a Place of Payment for that series, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities of the same
series and tenor, of any authorized denominations and of a like aggregate
principal amount.
 
<PAGE>   34
 
                                       26
305
 
     At the option of the Holder, Securities of any series may be exchanged for
other Securities of the same series and tenor, of any authorized denominations
and of a like aggregate principal amount, upon surrender of the Securities to be
exchanged at such office or agency. Whenever any Securities are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive.
 
     All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.
 
     Every Security presented or surrendered for registration of transfer or for
exchange shall (if so required by the Company or the Trustee) be duly endorsed,
or be accompanied by a written instrument of transfer in form satisfactory to
the Company and the Security Registrar duly executed, by the Holder thereof or
his attorney duly authorized in writing.
 
     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.
 
     The Company shall not be required (i) to issue, register the transfer of or
exchange Securities of any series during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section 1103 and ending
at the close of business on the day of such mailing, or (ii) to register the
transfer of or exchange any Security so selected for redemption in whole or in
part, except the unredeemed portion of any Security being redeemed in part.
 
     Notwithstanding any other provisions of this Section, unless and until it
is exchanged in whole or in part for Securities in definitive registered form, a
Global Security 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. The Trustee and the Company
 
<PAGE>   35
 
                                       27
                                                                             305
 
shall treat the Depositary or its nominee as the Holder of Global Securities for
all purposes hereof.
 
     If at any time the Depositary for any Securities of a series represented by
one or more Global Securities notifies the Company that it is unwilling or
unable to continue as Depositary for such Securities or if at any time the
Depositary for such Securities shall no longer be eligible under Section 101,
the Company shall appoint a successor Depositary with respect to such
Securities. If a successor Depositary for such Securities 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 301 that
such Securities be represented by one or more Global Securities shall no longer
be effective and the Company will execute, and the Trustee, upon receipt of a
Company Order for the authentication and delivery of definitive Securities of
such series, will authenticate and deliver, Securities of such series in
definitive registered form without coupons, in any authorized denominations, in
an aggregate principal amount equal to the principal amount of the Global
Security or Securities representing such Securities in exchange for such Global
Security or Securities.
 
     The Company may at any time and in its sole discretion determine that the
Securities of any series issued in the form of one or more Global Securities
shall no longer be represented by a Global Security or Securities. In such event
the Company will execute, and the Trustee, upon receipt of a Company Order for
the authentication and delivery of the definitive Securities of such series,
will authenticate and deliver, Securities of such series in definitive
registered form without coupons, in any authorized denominations, in an
aggregate principal amount equal to the principal amount of the Global Security
or Securities representing such Securities in exchange for such Global Security
or Securities.
 
     If specified by the Company pursuant to Section 301 with respect to
Securities represented by a Global Security, the Depositary for such Global
Security may surrender such Global Security in exchange in whole or in part for
Securities of the same series and tenor in definitive registered 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,
 
     (1) to the Person specified by such Depositary a new Security or Securities
of the same series and term, of any authorized denominations as requested by
such Person, in an aggregate principal amount equal to and in exchange for such
Person's beneficial interest in the Global Security; and
<PAGE>   36
 
                                       28
305,306
 
     (2) to such Depositary a new Global Security in a denomination equal to the
difference, if any, between the principal amount of the surrendered Global
Security and the aggregate principal amount of Securities authenticated and
delivered pursuant to clause (1) above.
 
     Every Person who takes or holds any beneficial interest in a Global
Security agrees that:
 
          (a) the Company and the Trustee may deal with the Depositary as sole
     owner of the Global Security and as the authorized representative of such
     Person;
 
          (b) such Person's rights in the Global Security shall be exercised
     only through the Depositary and shall be limited to those established by
     law and agreement between such Person and the Depositary and/or direct and
     indirect participants of the Depositary; and
 
          (c) the Depositary and its participants make book-entry transfers of
     beneficial ownership among, and receive and transmit distributions of
     principal and interest on the Global Securities to, such Persons in
     accordance with their own procedures.
 
SECTION 306.  Mutilated, Destroyed, Lost and Stolen Securities.
 
     If any mutilated Security is surrendered to the Trustee, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding.
 
     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 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 has been acquired by a bona fide
purchaser, the Company shall execute and upon its request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.
 
     In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.
 
     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
 
<PAGE>   37
 
                                       29
                                                                        306,307
 
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 issued pursuant to this Section in lieu of
any destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of that series duly issued hereunder.
 
     The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.
 
SECTION 307.  Payment of Interest; Interest Rights Preserved.
 
     Interest on any 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.
 
     Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:
 
          (1) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Securities of such series (or their
     respective Predecessor Securities) are registered at the close of business
     on a Special Record Date for the payment of such Defaulted Interest, which
     shall be fixed in the following manner. The Company shall notify the
     Trustee in writing of the amount of Defaulted Interest proposed to be paid
     on each Security of such series and the date of the proposed payment, and
     at the same time the Company shall deposit with the Trustee an amount of
     money equal to the aggregate amount proposed to be paid in respect of such
     Defaulted Interest or shall make arrangements satisfactory to the Trustee
     for such deposit prior to the date of the proposed payment, such money when
     deposited
 
<PAGE>   38
 
                                       30
307, 308
 
     to be held in trust for the benefit of the Persons entitled to such
     Defaulted Interest as in this clause provided. Thereupon, the Trustee shall
     fix a Special Record Date for the payment of such Defaulted Interest which
     shall be not more than 15 days and not less than 10 days prior to the date
     of the proposed payment and not less than 10 days after the receipt by the
     Trustee of the notice of the proposed payment. The Trustee shall promptly
     notify the Company of such Special Record Date and, in the name and at the
     expense of the Company, shall cause notice of the proposed payment of such
     Defaulted Interest and the Special Record Date therefor to be mailed,
     first-class postage prepaid, to each Holder of Securities of such series at
     his address as it appears in the Security Register, not less than 10 days
     prior to such Special Record Date. Notice of the proposed payment of such
     Defaulted Interest and the Special Record Date therefor having been so
     mailed, such Defaulted Interest shall be paid to the Persons in whose names
     the Securities of such series (or their respective Predecessor Securities)
     are registered at the close of business on such Special Record Date and
     shall no longer be payable pursuant to the following clause (2).
 
          (2) The Company may make payment of any Defaulted Interest on the
     Securities of any series in any other lawful manner not inconsistent with
     the requirements of any securities exchange on which such Securities may be
     listed, and upon such notice as may be required by such exchange, if, after
     notice given by the Company to the Trustee of the proposed payment pursuant
     to this clause, such manner of payment shall be deemed practicable by the
     Trustee.
 
     Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.
 
SECTION 308.  Persons Deemed Owners.
 
     Prior to due presentment of a 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 Security is registered as the owner of such Security
for the purpose of receiving payment of principal of (and premium, if any) and
(subject to Section 307) interest on such Security and for all other purposes
whatsoever, whether or not such Security be overdue,
 
<PAGE>   39
 
                                       31
                                                                308,309,310,401
 
and neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.
 
SECTION 309.  Cancellation.
 
     All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly cancelled by it. The Company may at any time deliver to

by this Indenture. All cancelled Securities held by the Trustee shall be
disposed of in accordance with its customary practices.

               (ii) will become due and payable at their Stated Maturity within
          one year, or
 
               (iii) are to be called for redemption within one year under
          arrangements satisfactory to the Trustee for the giving of notice of
          redemption by the Trustee in the name, and at the expense, of the
          Company,
 
       and the Company, in the case of (i), (ii) or (iii) above, has deposited
       or caused to be deposited with the Trustee as trust funds in trust for
       such purpose an amount sufficient to pay and discharge the entire
       indebtedness on such Securities not theretofore delivered to the Trustee
       for cancellation, for principal (and premium, if any) and interest 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

     herein provided for relating to the satisfaction and discharge of this
     Indenture have been complied with.
 
     Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to Subclause (B) of Clause (1) of

this Indenture, to the payment, either directly or through any Paying Agent

SECTION 501.  Events of Default.
 
     "Event of Default", wherever used herein with respect to Securities of any
series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):
 
          (1) default in the payment of any interest upon any Security of that
     series when it becomes due and payable, and continuance of such default for
     a period of 60 days; or
 
          (2) default in the payment of the principal of (or premium, if any,
     on) any Security of that series at its Maturity; or
 
          (3) default in the payment of any sinking fund payments, when and as
     due by the terms of a Security of that series, and continuance of such
     default for a period of 60 days; or
 
          (4) default in the performance, or breach, of any covenant or warranty
     of the Company in this Indenture (other than a covenant or warranty a
     default in whose performance or whose breach is elsewhere in this Section
     specifically dealt with or which has expressly been included in this
     Indenture solely for the benefit of series of Securities other than that
     series), and continuance of such default or breach for a period of 90 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 that 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;
     or

          (5) default by the Company in the payment of any principal of any
     Funded Debt of the Company outstanding in an aggregate principal amount in
     excess of $10,000,000 as and when the same shall become due and payable
     either at maturity, upon redemption, by declaration or otherwise, the
     effect of which default is to cause such Funded Debt to become, or to be
     declared, due prior to its stated maturity unless such default shall be
     cured, by payment or otherwise, within 30 days after the receipt by the
     Company of written notice of such default from the Trustee or from the
     Holders of at least 5% in principal amount of the Outstanding Securities of
     that series; or
 
          (6) the entry by a court having jurisdiction in the premises of (A) a
     decree or order for relief in respect of the Company in an involuntary case
     or proceeding under any applicable Federal or State bankruptcy, insolvency,
     reorganization or other similar law or (B) a decree or order adjudging the
     Company a bankrupt or insolvent, or approving as properly filed a petition
     seeking reorganization, arrangement, adjustment or composition of or in
     respect of the Company under any applicable Federal or State law, or
     appointing a custodian, receiver, liquidator, assignee, trustee,
     sequestrator or other similar official of the Company or of any substantial
     part of its property, or ordering the winding up or liquidation of its
     affairs, and the continuance of any such decree or order for relief or any
     such other decree or order unstayed and in effect for a period of 90
     consecutive days; or
 
          (7) the commencement by the Company of a voluntary case or proceeding
     under any applicable Federal or State bankruptcy, insolvency,
     reorganization or other similar law or of any other case or proceeding to
     be adjudicated a bankrupt or insolvent, or the consent by it to the entry
     of a decree or order for relief in respect of the Company in an involuntary
     case or proceeding under any applicable Federal or State bankruptcy,
     insolvency, reorganization or other similar law or to the commencement of
     any bankruptcy or insolvency case or proceeding against it, or the filing
     by it of a petition or answer or consent seeking reorganization or relief
     under any applicable Federal or State law, or the consent by it to the
     filing of such petition or to the appointment of or taking possession by a
     custodian, receiver, liquidator, assignee, trustee, sequestrator or similar
     official of the Company or of any substantial part of its property, or the
     making by it of an assignment for the benefit of creditors, or the
     admission by it in writing of its

     inability to pay its debts generally as they become due, or the taking of
     corporate action by the Company in furtherance of any such action; or
 
          (8) any other Event of Default provided with respect to Securities of
     that series.
 
SECTION 502.  Acceleration of Maturity; Rescission and Annulment.
 
     If an Event of Default with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of that series may declare the principal amount (or, if the Securities of that
series are Original Issue Discount Securities, such portion of the principal
amount as may be specified in the terms of that series) of all of the Securities
of that series to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by Holders), and upon any such declaration
such principal amount (or specified amount) shall become immediately due and
payable.
 
     At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if
 
          (1) the Company has paid or deposited with the Trustee a sum
     sufficient to pay
 
            (A) all overdue interest on all Securities of that series,
 
            (B) the principal of (and premium, if any, on) any Securities of
       that series which have become due otherwise than by such declaration of
       acceleration and interest thereon at the rate or rates prescribed
       therefor in such Securities,
 
            (C) to the extent that payment of such interest is lawful, interest
       upon overdue interest at the rate or rates prescribed therefor in such
       Securities, and
 
            (D) all sums paid or advanced by the Trustee hereunder and the
       reasonable compensation, expenses, disbursements and advances of the
       Trustee, its agents and counsel;
 
<PAGE>   44
 
                                       36
502,503
 
     and
 
          (2) all 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 513.
 
No such rescission shall affect any subsequent default or impair any right
consequent thereon.
 
SECTION 503.  Collection of Indebtedness and Suits for Enforcement by Trustee.
 
     The Company covenants that if
 
          (1) default is made in the payment of any installment of interest on
     any Security or any deposit of any sinking fund payment when such becomes
     due and payable and such default continues for a period of 60 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, the whole amount then due and payable on such
Securities for principal (and premium, if any) and interest and, to the extent
that payment of such interest shall be legally enforceable, interest on any
overdue principal (and premium, if any) and on any overdue interest, at the rate
or rates prescribed therefor in such Securities, and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.
 
     If the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Securities, wherever
situated.
 
     If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series
 
<PAGE>   45
 
                                       37
                                                                     503,504
 
by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.
 
SECTION 504.  Trustee May File Proofs of Claim.
 
     In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise,
 
          (i) to file and prove a claim for the whole amount of principal (and
     premium, if any) and interest owing and unpaid in respect of the Securities
     and to file such other papers or documents as may be necessary or advisable
     in order to have the claims of the Trustee (including any claim for the
     reasonable compensation, expenses, disbursements and advances of the
     Trustee, its agents and counsel) and of the Holders allowed in such
     judicial proceeding, and
 
          (ii) to collect and receive any moneys or other property payable or
     deliverable on any such claims and to distribute the same;
 
and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 607.
 
     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the
 
<PAGE>   46
 
                                       38
504,505,506,507
 
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.
 
SECTION 505.  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, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Securities in respect of which such judgment has been
recovered.
 
SECTION 506.  Application of Money Collected.
 
     Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium,
if any) or 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 payment of all amounts due the Trustee under Section
     607; and
 
          SECOND:  To the payment of the amounts then due and unpaid for
     principal of (and premium, if any) and interest on the Securities in
     respect of which or for the benefit of which such money has been collected,
     ratably, without preference or priority of any kind, according to the
     amounts due and payable on such Securities for principal (and premium, if
     any) and interest, respectively.
 
SECTION 507.  Limitation on Suits.
 
     No Holder of any Security of any series 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) such Holder has previously given written notice to the Trustee of
     a continuing Event of Default with respect to the Securities of that
     series;
 
<PAGE>   47
 
                                       39

          (2) the Holders of not less than 25% in principal amount of the
     Outstanding Securities of that series shall have made written request to
     the Trustee to institute proceedings in respect of such Event of Default in
     its own name as Trustee hereunder;
 
          (3) such Holder or Holders have offered to the Trustee reason-
     able indemnity against the costs, expenses and liabilities to be incurred
     in compliance with such request;
 
          (4) the Trustee for 60 days after its receipt of such notice, request
     and offer of indemnity has failed to institute any such proceeding; and
 
          (5) no direction inconsistent with such written request has been given
     to the Trustee during such 60-day period by the Holders of a majority in
     principal amount of the Outstanding Securities of that series;
 
it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all such
Holders.
 
SECTION 508.  Unconditional Right of Holders to Receive Principal, Premium and
  Interest.
 
     Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of (and premium, if any) and (subject to Section 307)
interest on such Security on the Stated Maturity or Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date) and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.
 
SECTION 509.  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
 
<PAGE>   48
 
                                       40
509,510,511,512
 
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 510.  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
306, no right or remedy herein conferred upon or reserved to the Trustee or to
the Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.
 
SECTION 511.  Delay or Omission Not Waiver.
 
     No delay or omission of the Trustee or of any Holder of any Securities to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article or by law to
the Trustee or to the Holders may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders, as the case may
be.
 
SECTION 512.  Control by Holders.
 
     The Holders of a majority in principal amount of the Outstanding Securities
of any series shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred on the Trustee, with respect to the Securities of
such series, provided that
 
          (1) such direction shall not be in conflict with any rule of law or
     with this Indenture, and
 
          (2) the Trustee may take any other action deemed proper by the Trustee
     which is not inconsistent with such direction.

SECTION 513.  Waiver of Past Defaults.
 
     The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any past default hereunder with respect to such
series and its consequences, except a default
 
          (1) in the payment of the principal of (or premium, if any) or
     interest on any Security of such series, or
 
          (2) in respect of a covenant or provision hereof which under Article
     Nine cannot be modified or amended without the consent of the Holder of
     each Outstanding Security of such series affected.
 
     Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.
 
SECTION 514.  Undertaking for Costs.
 
     All parties to this Indenture agree, and each Holder of any Security by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant, other
than the Trustee, in such suit of an undertaking to pay the costs of such suit,
and that such court may in its discretion assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in such suit, having due
regard to the merits and good faith of the claims or defenses made by such party
litigant; but the provisions of this Section shall not apply to any suit
instituted by the Company, to any suit instituted by the Trustee, to any suit
instituted by any Holder, or group of Holders, holding in the aggregate more
than 10% in principal amount of the Outstanding Securities of any series, or to
any suit instituted by any Holder for the enforcement of the payment of the
principal of (or premium, if any) or interest on any Security on or after the
Stated Maturity or Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date).

SECTION 515.  Waiver of Stay or Extension Laws.
 
     The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

          (1) the Trustee undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture, and no implied covenants
     or obligations shall be read into this Indenture against the Trustee; and
 
          (2) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture; but in
     the case of any such certificates or opinions which by any provision hereof
     are specifically required to be furnished to the Trustee, the Trustee shall
     be under a duty to examine the same to determine whether or not they
     conform to the requirements of this Indenture.
 
     (b) In case an Event of Default has occurred and is continuing, the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

     (c) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own wilful misconduct, except that
 
          (1) this Subsection shall not be construed to limit the effect of
     Subsection (a) of this Section;
 
          (2) the Trustee shall not be liable for any error of judgment made in
     good faith by a Responsible Officer, unless it shall be proved that the
     Trustee was negligent in ascertaining the pertinent facts;
 
          (3) the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the direction
     of the Holders of a majority in principal amount of the Outstanding
     Securities of any series, determined as provided in Section 512, relating
     to the time, method and place of conducting any proceeding for any remedy
     available to the Trustee, or exercising any trust or power conferred upon
     the Trustee, under this Indenture with respect to the Securities of such
     series; and
 
          (4) no provision of this Indenture shall require the Trustee to expend
     or risk its own funds or otherwise incur any financial liability in the
     performance of any of its duties hereunder, or in the exercise of any of
     its rights or powers, if it shall have reasonable grounds for believing
     that repayment of such funds or adequate indemnity against such risk or
     liability is not reasonably assured to it.
 
     (d) Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section.
 
SECTION 602.  Notice of Defaults.
 
     Within 90 days after the occurrence of any default hereunder with respect
to the Securities of any series, the Trustee shall transmit by mail to all
Holders of Securities of such series, as their names and addresses appear in the
Security Register, notice of such default hereunder known to the Trustee, unless
such default shall have been cured or waived; provided, however, that, except in
the case of a default in the payment of the principal of (or premium, if any) or
interest on any Security of such series or in the payment of any sinking fund
instalment with respect to Securities of such series, the Trustee shall be
protected in withholding such notice if and so
 
<PAGE>   52
 
                                       44
602,603
 
long as a trust committee of Responsible Officers of the Trustee in good faith
determine that the withholding of such notice is in the interest of the Holders
of Securities of such series; and provided, further, that in the case of any
default of the character specified in Section 501(4) with respect to Securities
of such series, no such notice to Holders shall be given until at least 60 days
after the occurrence thereof. For the purpose of this Section, the term
"default" means any event which is, or after notice or lapse of time or both
would become, an Event of Default with respect to Securities of such series.

     and may, in the absence of bad faith on its part, rely upon an Officers'
     Certificate;
 
          (d) the Trustee may consult with counsel and the advice of such

     hereunder in good faith and in reliance thereon;
 
          (e) the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request or direction
     of any of the Holders pursuant to this Indenture, unless such Holders shall

     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or
     document, but the Trustee, in its discretion, may make such further inquiry
     or investigation into such facts or matters as it may see fit, and, if the
     Trustee shall determine to make such further inquiry or investigation, it
     shall be entitled to examine the books, records and premises of the
     Company, personally or by agent or attorney;
 
          (g) the Trustee may execute any of the trusts or powers hereunder or

Trustee's certificates of authentication, shall be taken as the statements of
the Company, and the Trustee or any Authenticating Agent assumes no re-

other agent.

     of an express trust);
 
          (2) except as otherwise expressly provided herein, to reimburse the

     administration of the trust or trusts hereunder, including the costs and
     expenses of defending itself against any claim or liability in connection
     with the exercise or performance of any of its powers or duties hereunder.
 
     As security for the performance of the obligations of the Company under
this Section the Trustee shall have a lien prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held

Indenture Act this Indenture with respect to the Securities of more than one
series.
 
SECTION 609.  Corporate Trustee Required; Eligibility.
 
     There shall at all times be a Trustee hereunder which shall be a

laws to exercise corporate trust powers, having a combined capital and surplus
of at least $50,000,000, subject to supervision or examination by Federal or
State authority and having its Corporate Trust Office in The City of New York.
If such corporation publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. The Trustee shall not be an
obligor upon the Securities or an Affiliate thereof. 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 610.  Resignation and Removal; Appointment of Successor.
 
     (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.
 
     (b) The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 611 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.
 
     (c) The Trustee may be removed at any time with respect to the Securities
of any series by Act of the Holders of a majority in principal amount of the

     (d) If at any time:
 
          (1) the Trustee shall fail 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 609 and shall
     fail to resign after written request therefor by the Company or by any such
     Holder, or
 
          (3) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property
     shall be appointed or any public officer shall take charge or control of
     the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation,
 
then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (ii) subject to Section 514, 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 shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Company, by a Board Resolution,
shall promptly appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of
such series and that at any time there shall be only one Trustee with respect to
the Securities of any particular series) and shall comply with the applicable
requirements of Section 611. 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 611, 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

                                       49
                                                                         610,611

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 611, any Holder who has been a bona fide Holder of a Security of such
series for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.
 
     (f) The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series by mailing
written notice of such event by first-class mail, postage prepaid, to all
Holders of Securities of such series as their names and addresses appear in the
Security Register. Each notice shall include the name of the successor Trustee
with respect to the Securities of such series and the address of its Corporate
Trust Office.
 
SECTION 611.  Acceptance of Appointment by Successor.
 
     (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request
of the Company or the successor Trustee, such retiring Trustee shall, upon
payment of its charges, execute and deliver an instrument transferring to such
successor Trustee all the rights, powers and trusts of the retiring Trustee and
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder.
 
     (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the
 
<PAGE>   58
 
                                       50
611,612
 
appointment of such successor Trustee relates, (2) if the retiring Trustee is
not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.
 
     (c) Upon request of any such successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Trustee all such rights, powers and trusts referred to in
paragraph (a) or (b) of this Section, as the case may be.
 
     (d) No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified and eligible under
this Article and the Trust Indenture Act.
 
SECTION 612.  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

                                                                     612,613,614
 
this Article, without the execution or filing of any paper or any further act on
the part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.
 
SECTION 613.  Preferential Collection of Claims Against Company.
 
     Reference is made to Section 311 of the Trust Indenture Act. For purposes
of Section 311(b),
 
          (1) the term "cash transaction" means any transaction in which full
     payment for goods or securities sold is made within seven days after
     delivery of the goods or securities in currency or in checks or other
     orders drawn upon banks or bankers and payable upon demand;
 
          (2) the term "self-liquidating paper" means any draft, bill of
     exchange, acceptance or obligation which is made, drawn, negotiated or
     incurred by the Company for the purpose of financing the purchase,
     processing, manufacturing, shipment, storage or sale of goods, wares or
     merchandise and which is secured by documents evidencing title to,
     possession of, or a lien upon, the goods, wares or merchandise or the
     receivables or proceeds arising from the sale of the goods, wares or
     merchandise previously constituting the security, provided the security is
     received by the Trustee simultaneously with the creation of the creditor
     relationship with the Company arising from the making, drawing, negotiating
     or incurring of the draft, bill of exchange, acceptance or obligation.
 
SECTION 614.  Appointment of Authenticating Agent.
 
     At any time when any of the Securities remain Outstanding 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 exchange, registration of
transfer or partial redemption thereof or pursuant to Section 306, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
 
<PAGE>   60
 
                                       52
614
 
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business
under the laws of the United States of America, any State thereof or the
District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined capital and surplus of not less than $50,000,000 and subject
to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.
 
     Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.
 
     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof 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 may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders of
Securities of the series with respect to which such Authenticating Agent will
serve, as their names and addresses appear in the Security Register. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the
 
<PAGE>   61
 
                                       53
                                                                         614,701
 
rights, powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section.
 
     The Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payments, subject to the provisions
of Section 607.
 
     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 the Trustee's certificate of authentication, an alternate
certificate of authentication in the following form:
 
     This is one of the Securities of the series designated therein referred to
in the within-mentioned Indenture.

     Date, a list, in such form as the Trustee may reasonably require, of the
     names and addresses of the Holders as of such Regular Record Date, and
 
          (b) at such other times as the Trustee may request in writing, within

excluding from any such list names and addresses received by the Trustee in its
capacity as Security Registrar.
 
SECTION 702.  Preservation of Information; Communications to Holders.
 
     (a) The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 701 and the names and
addresses of Holders received by the Trustee in its capacity as Security
Registrar. The Trustee may destroy any list furnished to it as provided in
Section 701 upon receipt of a new list so furnished.
 
     (b) If three or more Holders (herein referred to as "applicants") apply in
writing to the Trustee, and furnish to the Trustee reasonable proof that each
such applicant has owned a Security for a period of at least six months
preceding the date of such application, and such application states that the
applicants desire to communicate with other Holders with respect to their rights
under this Indenture or under the Securities and is accompanied by a copy of the
form of proxy or other communication which such applicants propose to transmit,
then the Trustee shall, within five business days after the receipt of such
application, at its election, either
 
          (i) afford such applicants access to the information preserved at the
     time by the Trustee in accordance with Section 702(a), or
 
          (ii) inform such applicants as to the approximate number of Holders
     whose names and addresses appear in the information preserved at the time
     by the Trustee in accordance with Section 702(a), and as to the approximate
     cost of mailing to such Holders the form of proxy or other communication,
     if any, specified in such application.
 
     If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Holder whose name and address appear in the information preserved
at the time by the Trustee in accordance with Section 702(a) a copy of the form
of proxy or other communication which is specified in such request, with
reasonable promptness after a tender to the Trustee of the material to be mailed
and of payment, or provision for the payment, of the reasonable expenses of
mailing, unless within five days after such tender the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interest of the Holders
or would be in violation of applicable law.

Such written statement shall specify the basis of such opinion. If the
Commission, after opportunity for a hearing upon the objections specified in the
written statement so filed, shall enter an order refusing to sustain any of such
objections or if, after the entry of an order sustaining one or more of such
objections, the Commission shall find, after notice and opportunity for hearing,
that all the objections so sustained have been met and shall enter an order so
declaring, the Trustee shall mail copies of such material to all such Holders
with reasonable promptness after the entry of such order and the renewal of such
tender; otherwise the Trustee shall be relieved of any obligation or duty to
such applicants respecting their application.
 
     (c) Every Holder of Securities, by receiving and holding the same, agrees
with the Company and the Trustee that neither the Company nor the Trustee nor
any agent of either of them shall be held accountable by reason of the
disclosure of any such information as to the names and addresses of the Holders
in accordance with Section 702(b), regardless of the source from which such
information was derived, and that the Trustee shall not be held accountable by
reason of mailing any material pursuant to a request made under Section 702(b).

     Any Trustee's report required pursuant to Section 313(a) of the Trust
Indenture Act shall be dated as of August 1, and shall be transmitted within 60
days after August 1 of each year, commencing with the year 1995, by mail to all
Holders, as their names and addresses appear in the Security Register. A copy of
each such report shall, at the time of such transmission to Holders, be filed by
the Trustee with each stock exchange upon which any Securities are listed, with
the Commission and with the Company. The Company will notify the Trustee when
any Securities are listed on any stock exchange.
 
SECTION 704.  Reports by Company.
 
     The Company shall file with the Trustee, within 15 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 which the Company may be
required to file with the Commission pursuant to Section 13 or Section 15(d) of

     herein and in the Securities; or
 
          (2) to add to the covenants of the Company for the benefit of the
     Holders of all or any series of Securities (and if such covenants are to be
     for the benefit of less than all series of Securities, stating that such
     covenants are expressly being included solely for the 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; or

     and with or without interest coupons; or
 
          (5) to change or eliminate any of the provisions of this Indenture,
     provided that any such change or elimination shall become effective only
     when there is no Security Outstanding of any series created prior to the
     execution of such supplemental indenture which is entitled to the benefit
     of such provision; or
 
          (6) to secure the Securities of any series pursuant to the
     requirements of Section 1005 or otherwise; or
 
          (7) to establish the form or terms of Securities of any series as

     hereunder by a successor Trustee with respect to the Securities of one or
     more series and to 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, pursuant to the requirements
     of Section 611(b); or
 
          (9) to cure any ambiguity, 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 which shall not adversely affect the interests of the
     Holders of Securities of any series in any material respect.
 
SECTION 902.  Supplemental Indentures with Consent of Holders.
 
     With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company, when authorized by a Board Resolution, and the Trustee may
enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the rights of the
Holders of Securities of such series under this Indenture; provided, however,
that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Security affected thereby,
 
          (1) change the Stated Maturity of the principal of, or any instalment
     of principal of 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 reduce the amount of the principal of an
     Original Issue Discount Security that would be due and payable upon a
     declaration of acceleration of the Maturity thereof pursuant to Section
     502, or change any Place of Payment where, or the coin or currency in

                                                                     902,903,904
 
     required for any waiver (of compliance with certain provisions of this
     Indenture or certain defaults hereunder and their consequences) provided
     for in this Indenture, or
 
          (3) modify any of the provisions of this Section or Section 513,
     except to increase any such percentage or to provide that certain other
     provisions of this Indenture cannot be modified or waived without the
     consent of the Holder of each Outstanding Security affected thereby,
     provided, however, that this clause shall not be deemed to require the
     consent of any Holder with respect to changes in the references to "the
     Trustee" and concomitant changes in this Section, or the deletion of this
     proviso, in accordance with the requirements of Sections 611(b) and 901(8).
 
A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture 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 shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.
 
SECTION 903.  Execution of Supplemental Indentures.
 
     In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 601) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.
 
SECTION 904.  Effect of Supplemental Indentures.
 
     Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and

904,905,906,1001,1002
 
every Holder of Securities theretofore or thereafter authenticated and delivered
hereunder shall be bound thereby.
 
SECTION 905.  Conformity with Trust Indenture Act.
 
     Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.
 
SECTION 906.  Reference in Securities to Supplemental Indentures.
 
     Securities of any series authenticated and delivered after the execution of
any supplemental indenture pursuant to this Article may, and shall if required
by the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company shall so determine,
new Securities of any series so modified as to conform, in the opinion of the
Trustee and the Company, to any such supplemental indenture may be prepared and
executed by the Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities of such series.
 
                                  ARTICLE TEN
 
                                   COVENANTS
 
SECTION 1001.  Payment of Principal, Premium and Interest.
 
     The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of (and premium,
if any) and interest on the Securities of that series in accordance with the
terms of the Securities and this Indenture.
 
SECTION 1002.  Maintenance of Office or Agency.
 
     The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Company in respect of the Securities of that series and this Indenture
may be served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands
 
<PAGE>   69
 
                                       61
                                                                       1002,1003
 
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.
 
     The Company may also from time to time designate one or more other offices
or agencies where the Securities of one or more series may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency
in each Place of Payment for Securities of any series for such purposes. The
Company will give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency.
 
SECTION 1003.  Money for Securities Payments to Be Held in Trust.
 
     If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities, it will, on or before each due date of the
principal of (and 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 (and premium, if any) or interest
so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and will promptly notify the Trustee of its
action or failure so to act.
 
     Whenever the Company shall have one or more Paying Agents for any series of
Securities, it will, prior to each due date of the principal of (and premium, if
any) or interest on any Securities of that series, deposit with a Paying Agent a
sum sufficient to pay the principal (and premium, if any) or interest so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Company will promptly notify the Trustee of its action or
failure so to act. For purposes of this Section, should a due date for principal
of (and premium, if any), interest on, or sinking fund payment with respect to
any series of Securities not be on a Business Day, such payment shall be due on
the next Business Day.
 
     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:
 
<PAGE>   70
 
                                       62
1003
 
          (1) hold all sums held by it for the payment of the principal of (and
     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 (and premium, if any) or interest on the Securities of
     that series; and
 
          (3) at any time during the continuance of any such default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent.
 
     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which 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 the principal of (and premium, if any)
or interest on any Security of any series and remaining unclaimed for one year
after such principal (and 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
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 Borough of Manhattan, The City of New York, 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 1004.  Corporate Existence
 
     Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence, rights (charter and statutory) and franchises; provided, however,
that the Company shall not be required to preserve any such right or franchise
if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company and that the loss
thereof is not disadvantageous in any material respect to the Holders.
 
SECTION 1005.  Limitation on Liens.
 
     The Company will not itself, and will not permit any Restricted Subsidiary
to, incur, issue, assume or guarantee any indebtedness for money borrowed (all
such indebtedness for money borrowed being hereinafter in this Article called
"Debt"), secured by a Mortgage on any Principal Property or on any shares of
stock or Indebtedness of any Restricted Subsidiary, without effectively
providing that the Securities of any series (together with, if the Company shall
so determine, any other indebtedness of the Company or such Restricted
Subsidiary which is not subordinate in right of payment to the prior payment in
full of the Securities of any series) shall be secured equally and ratably with
(or prior to) such secured Debt, so long as such secured Debt shall be so
secured, unless, after giving effect thereto, the aggregate amount of all Debt
so secured would not exceed 10% of Consolidated Net Tangible Assets as of a date
within 150 days prior to such determination; provided, however, that this
Section shall not apply to, and there shall be excluded from secured Debt in any
computation under this Section, Debt secured by:
 
          (1) Mortgages existing at the date of this Indenture;
 
          (2) Mortgages on property of, or on any shares of stock or
     Indebtedness of, any corporation existing at the time such corporation
     becomes a Restricted Subsidiary;
 
          (3) Mortgages in favor of the Company or any Restricted Subsidiary;
 
          (4) Mortgages on property, shares of stock or Indebtedness existing at
     the time of acquisition thereof (including acquisition through merger,
     consolidation or other reorganization) or to secure the payment of all or
     any part of the purchase price thereof or construction thereon or to secure
     any Debt incurred prior to, at the time of, or
 
<PAGE>   72
 
                                       64

     within 180 days after the later of the acquisition, the completion of
     construction or the commencement of full operation of such property or
     within 180 days after the acquisition of such shares or Indebtedness for
     the purpose of financing all or any part of the purchase price thereof or
     construction thereon, it being understood that if a commitment for such
     financing is obtained prior to or within such 180-day period, the
     applicable Mortgage shall be deemed to be included in this Clause (4)
     whether or not such Mortgage is created within such 180-day period;
 
          (5) Mortgages on property owned or leased by the Company or a
     Restricted Subsidiary in favor of the United States of America or any State
     thereof, or any department, agency or instrumentality or political
     subdivision of the United States of America or any State thereof, or in
     favor of any other country or any political subdivision thereof, or in
     favor of holders of securities issued by any such entity, pursuant to any

                            REDEMPTION OF SECURITIES
 
SECTION 1101.  Applicability of Article.
 
     Securities of any series which are redeemable before their Stated Maturity
shall be redeemable in accordance with their terms and (except as otherwise
specified as contemplated by Section 301 for Securities of any series) in
accordance with this Article.
 
SECTION 1102.  Election to Redeem; Notice to Trustee.
 
     The election of the Company to redeem any Securities shall be evidenced by
a Board Resolution. In case of any redemption at the election of the Company of
less than all the Securities of any series, the Company shall, at least five
Business Days prior to the last date for the giving of notice of such redemption
(unless a shorter notice shall be satisfactory to the Trustee), notify the
Trustee of such Redemption Date and of the principal amount of Securities of
such series to be redeemed. In the case of any redemption of Securities prior to
the expiration of any restriction on such redemption provided in the terms of
such Securities or elsewhere in this Indenture, the Company shall furnish the
Trustee with an Officers' Certificate evidencing compliance with such
restriction.
 
SECTION 1103.  Selection by Trustee of Securities to Be Redeemed.
 
     If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 40 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions (equal to the minimum authorized denomination for
Securities of that series or any integral multiple thereof) of the principal
amount of Securities of such series of a denomination larger than the minimum
authorized denomination for Securities of that series.
 
     The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption and, in the case of any Securities selected for partial
redemption, the principal amount thereof to be redeemed. If the Securities of
any series to be redeemed consist of Securities having different dates on which
the principal is payable or different rates of
 
<PAGE>   75
 
                                       67
                                                                       1103,1104
 
interest, or different methods by which interest may be determined or have any
other different tenor or terms, then the Company may, by written notice to the
Trustee, direct that the Securities of such series to be redeemed shall be
selected from among the groups of such Securities having specified tenor or
terms and the Trustee shall thereafter select the particular Securities to be
redeemed in the manner set forth in the preceding paragraph from among the group
of such Securities so specified.
 
     For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion
of the principal amount of such Securities which has been or is to be redeemed.
 
SECTION 1104.  Notice of Redemption.
 
     Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 15 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at his address appearing in the
Security Register.
 
     All notices of redemption shall state:
 
          (1) the Redemption Date,
 
          (2) the Redemption Price,
 
          (3) if less than all the Outstanding Securities of any series are to
     be redeemed, the identification (and, in the case of partial redemption,
     the principal amounts) of the particular Securities to be redeemed,
 
          (4) that on the Redemption Date the Redemption Price will become due
     and payable upon each such Security to be redeemed and, if applicable, that
     interest thereon will cease to accrue on and after said date,
 
          (5) the place or places where such Securities are to be surrendered
     for payment of the Redemption Price, and
 
          (6) that the redemption is for a sinking fund, if such is the case.
 
     Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

SECTION 1105.  Deposit of Redemption Price.
 
     On or prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date.
 
SECTION 1106.  Securities Payable on Redemption Date.
 
     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security 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 instalments of interest whose
Stated Maturity is on or prior to the Redemption Date shall be payable to the
Holders of such Securities, or one or more Predecessor Securities, registered as
such at the close of business on the relevant Record Dates according to their
terms and the provisions of Section 307.
 
     If any 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 1107.  Securities Redeemed in Part.
 
     Any Security which is to be redeemed only in part shall be surrendered at a
Place of Payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Security without service
charge, a new Security or Securities of the same series and tenor, of any
authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.

                                 SINKING FUNDS
 
SECTION 1201.  Applicability of Article.
 
     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.
 
     The minimum amount of any sinking fund payment provided for by the terms of
Securities of any series is herein referred to as a "mandatory sinking fund
payment", and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment". 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 1202. 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 1202.  Satisfaction of Sinking Fund Payments with Securities.
 
     The Company (1) may deliver Outstanding Securities of a series (other than
any previously called for redemption) and (2) 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 1203.  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
 
<PAGE>   78
 
                                       70
1203,1301,1302
 
any, which is to be satisfied by delivering and crediting Securities of that
series pursuant to Section 1202 and will also deliver to the Trustee any
Securities to be so delivered. Not less than 45 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 1103 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 1104. Such notice having been
duly given, the redemption of such Securities shall be made upon the terms and
in the manner stated in Sections 1106 and 1107.

                                   DEFEASANCE
 
SECTION 1301.  Applicability of Article; Company's Option to Effect
  Defeasance.

time, with respect to the Securities of a series, elect to have Section 1302 be
applied to the Outstanding Securities of such series upon compliance with the
conditions set forth below in this Article Thirteen.
 
SECTION 1302.  Defeasance and Discharge.
 
     Upon the Company's exercise of the above option applicable to this Section,
the Company shall be deemed to have been discharged from its obligations with
respect to the Outstanding Securities of such series on the date the conditions
set forth below 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 the Outstanding Securities of
such series and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following which shall survive until
otherwise terminated or discharged hereunder:  (A) the rights of Holders of
Outstanding Securities of such series to receive, solely from the trust fund
described in Section 1304 and as more fully set forth in such Section, payments
in respect of the principal of (and premium, if any) and interest on such
Securities when such payments are due, (B) the Company's obligations with
respect to such Securities under Sections 304, 305, 306, 1002 and 1003, (C) the

powers, trusts, duties, and immunities of the Trustee hereunder and (D) this
Article Thirteen.
 
SECTION 1303.  Conditions to Defeasance.
 
     The following shall be the conditions to application of Section 1302 to the
Outstanding Securities of such series:
 
          (1) the Company shall irrevocably have deposited or caused to be
     deposited with the Trustee (or another trustee satisfying the requirements
     of Section 609 who shall agree to comply with the provisions of this
     Article Thirteen applicable to it) as trust funds in trust for the purpose
     of making the following payments, specifically pledged as security for, and
     dedicated solely to, the benefit of the Holders of such Securities, (A)
     money in an amount, or (B) U.S. Government Obligations which through the
     scheduled payment of principal and interest in respect thereof in
     accordance with their terms will provide, not later than one day before the
     due date of any payment, money in an amount, or (C) a combination thereof,
     sufficient, in the opinion of a nationally recognized firm of independent
     public accountants expressed in a written certification thereof delivered
     to the Trustee, to pay and discharge, and which shall be applied by the
     Trustee (or other qualifying trustee) to pay and discharge, (i) the
     principal of (and premium, if any, on) and each installment of principal of
     (and premium, if any) and interest on the Outstanding Securities of such
     series on the Stated Maturity of such principal or installment of principal
     or interest and (ii) any mandatory sinking fund payments or analogous
     payments applicable to the Outstanding Securities of such series on the day
     on which such payments are due and payable in accordance with the terms of
     this Indenture and of such Securities. For this purpose, "U.S. Government
     Obligations" means securities that are (x) direct obligations of the United
     States of America for the payment of which its full faith and credit is
     pledged or (y) obligations of a Person controlled or supervised by and
     acting as an agency or instrumentality of the United States of America,
     which, in either case, are not callable or redeemable at the option of the
     issuer thereof, and shall also include a depository receipt issued by a
     bank (as defined in Section 3(a)(2) of the Securities Act of 1933, as
     amended) as custodian with respect to any such U.S. Government Obligation
     or a specific payment of principal of or interest on any such U.S.
     Government Obligation held by such custodian for the account of the holder
     of such depository receipt, provided that (except as required by law) such
     custodian is not
<PAGE>   80
 
                                       72
1303
 
     authorized to make any deduction from the amount payable to the holder of
     such depository receipt from any amount received by the custodian in
     respect of the U.S. Government Obligation or the specific payment of
     principal of or interest on the U.S. Government Obligation evidenced by
     such depository receipt.
 
          (2) No Event of Default or event which with notice or lapse of time or
     both would become an Event of Default with respect to the Securities of
     such series shall have occurred and be continuing on the date of such
     deposit.
 
          (3) Such defeasance shall not cause the Trustee for the Securities of
     such series to have a conflicting interest as defined in Section 310(b) of
     the Trust Indenture Act with respect to any securities of the Company.
 
          (4) Such defeasance shall not result in a breach or violation of, or
     constitute a default under this Indenture or any other agreement or
     instrument to which the Company is a party or by which it is bound.
 
          (5) Such defeasance shall not cause any Securities of such series then
     listed on any registered national securities exchange under the Securities
     Exchange Act of 1934, as amended, to be delisted.
 
          (6) Such defeasance shall be effected in compliance with any
     additional terms, conditions or limitations which may be imposed on the
     Company in connection therewith pursuant to Section 301.
 
          (7) The Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent provided for in this Indenture relating to the defeasance under
     Section 1302 have been complied with.
 
     Notwithstanding the foregoing, if an Event of Default specified in
Subsection 501(5) or 501(6), or an event which with lapse of time would become
such an Event of Default, shall occur during the period ending on the 91st day
after the date of the deposit referred to in Clause (1) or, if longer, ending on
the day following the expiration of the longest preference period applicable to
the Company in respect of such deposit, then, effective upon such occurrence,
the defeasance and such deposit shall be rescinded and annulled, and the
Company, the Trustee and the Holders of the Securities of such series shall be
restored to their former positions.

SECTION 1304.  Deposited Money and U.S. Government Obligations to be
  Held in Trust; Other Miscellaneous Provisions.
 
     Subject to the provisions of the last paragraph of Section 1003, all money
and U.S. Government Obligations (including the proceeds thereof) deposited with
the Trustee (or other qualifying trustee -- collectively, for purposes of this
Section 1304, the "Trustee") pursuant to Section 1303 in respect of the
Outstanding Securities of such series shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent), to the Holders of such
Securities, of all sums due and to become due thereon in respect of principal
(and premium, if any) and interest, but such money need not be segregated from
other funds except to the extent required by law.
 
     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1303 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of the Outstanding Securities of such series.
 
     Anything in this Article Thirteen to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 1303 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent defeasance.
 
     This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counter-parts
shall together constitute but one and the same instrument.

          (4) a statement as to whether, in the opinion of each such individual,
     such condition or covenant has been complied with.
 
SECTION 103.  Form of Documents Delivered to Trustee.

representations by, counsel, unless such officer knows that the certificate or
opinion or representations with respect to the matters upon which his

or other action provided by this Indenture to be given or taken by Holders may
be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Holders in person or by agent duly appointed in writing;
and, except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments are delivered to the Trustee and,
where it is hereby expressly required, to the Company. Such instrument or
instruments (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the "Act" of the Holders signing such instrument or
instruments. Proof of execution of any such instrument or of a writing

                                       10
 104,105,106
 
tion, 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 the record date, but only the Holders of record at the
close of business on the record date shall be deemed to be Holders for the
purposes of determining whether Holders of the requisite proportion of the
Outstanding Securities or a series thereof 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 or a series
thereof shall be computed as of the record date.
 
     (e) Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Holder of any Security shall bind every future Holder of the
same Security and the Holder of every Security issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done, omitted or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.
 
SECTION 105.  Notices, Etc., to Trustee and Company.
 
     Any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with,
 
          (1) the Trustee by any Holder or by the Company shall be sufficient
     for every purpose hereunder if made, given, furnished or filed in writing
     to or with the Trustee at its Corporate Trust Office, Attention: Corporate
     Trust Department, or
 
          (2) the Company by the Trustee or by any Holder shall be sufficient
     for every purpose hereunder (unless otherwise herein expressly provided) if
     in writing and mailed, first-class postage prepaid, to the Company
     addressed to it at the address of its principal office specified in the
     first paragraph of this instrument or at any other address previously
     furnished in writing to the Trustee by the Company.
 
SECTION 106.  Notice to Holders; Waiver.
 
     Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register,
 
<PAGE>   20

not later than the latest date, and not earlier than the earliest date,
prescribed for the giving of such notice. 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. Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice. Waivers of notice by Holders shall be filed with

SECTION 203.  Form of Reverse of Security.
 
     This Security is one of a duly authorized issue of subordinated securities
of the Company (herein called the "Securities"), issued and to be issued in one
or more series under an Indenture, dated as of March 1, 1995 (herein called the
"Indenture"), between the Company and Chemical Bank, as Trustee (herein called
the "Trustee", which term includes any successor trustee under the Indenture),
to which Indenture and all indentures supplemental thereto reference is hereby
made for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and the Holders of the
Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered. This Security is one of the series designated on
the face hereof[, limited in aggregate principal amount to $............].
 
     [If applicable, insert -- Subject to and upon compliance with the
provisions of the Indenture, the Holder of this Security is entitled, at his
option, at any time on or before the close of business on                 or in
case this Security or a portion hereof is called for redemption, then in respect
of this Security or such portion hereof until and including, but (unless the
Company defaults in making the payment due upon redemp-

tion) not after, the close of business on the Redemption Date, to convert this
Security (or any portion of the principal amount hereof which is $1,000 or an
integral multiple thereof), at the [principal amount hereof] [If the Security is
an Original Issue Discount Security, insert appropriate amount], or of such
portion, into fully paid and non-assessable shares (calculated as to each
conversion to the nearest 1/100 of a share) of Common Stock of the Company at an
initial Conversion Price equal to $        per share of Common Stock (or at the
current adjusted Conversion Price if an adjustment has been made as provided in
the Indenture) by surrender of this Security, together with the conversion
notice hereon duly executed, to the Company at the office or agency of the
Company in the Borough of Manhattan, the City and State of New York, at which
the principal of (and premium, if any) and interest on this Security shall be
payable, accompanied by written notice to the Company that the Holder hereof
elects to convert this Security, or if less than the entire principal amount
hereof is to be converted, the portion hereof to be converted, and, in case such
surrender shall be made during the period from the close of business on any
Regular Record Date next preceding any Interest Payment Date to the opening of
business on such Interest Payment Date unless this Security or the portion
hereof being converted has been called for redemption on a Redemption Date
within such period, also accompanied by payment to the Company or its order, in
New York Clearing House funds or other funds acceptable to the Company, of an
amount equal to the interest payable on such Interest Payment Date on the
principal amount of this Security then being converted. Subject to the aforesaid
requirement for payment by the Holder hereof and, in the case of a conversion
after the Regular Record Date next preceding any Interest Payment Date and on or
before such Interest Payment Date, to the right of the Holder of this Security
(or any Predecessor Security) of record at such Regular Record Date to receive
an installment of interest, no payment or adjustment is to be made on conversion
for interest accrued hereon or (with certain exceptions provided in the
Indenture) for dividends on the Common Stock issued on conversion. No fractions
of shares or scrip representing fractions of shares will be issued on
conversion, but instead of any fractional interest the Company shall pay a cash
adjustment as provided in the Indenture. The Conversion Price is subject to
adjustment as provided in the Indenture. In addition, the Indenture provides
that in case of certain consolidations or mergers to which the Company is a
party or transfer of substantially all of the assets of the Company, the
Indenture shall be amended, without the consent of any Holders of Securities, so
that this Security, if then outstanding, will be

convertible thereafter, during the period this Security shall be convertible as
specified above, only into the kind and amount of securities, cash and other
property receivable upon the consolidation, merger or transfer by a holder of
the number of shares of Common Stock into which this Security might have been
converted immediately prior to such consolidation, merger, sale or transfer
(assuming such holder of Common Stock failed to exercise any rights of election
and received per share the kind and amount received per share by a plurality of
non-electing shares).].

                                       25
                                                                     301,302,303
 
such action shall be certified by the Secretary or an Assistant Secretary of the
Company and delivered to the Trustee at or prior to the delivery of the
Officers' Certificate setting forth the terms of the series.
 
SECTION 302.  Denominations.
 
     The Securities of each series shall be issuable in registered form without
coupons in such denominations as shall be specified as contemplated by Section
301. In the absence of any such provisions with respect to the Securities of any
series, the Securities of such series shall be issuable in denominations of
$1,000 and any integral multiple thereof.
 
SECTION 303.  Execution, Authentication, Delivery and Dating.
 
     The Securities shall be executed on behalf of the Company by its Chairman
of the Board, its President or one of its Vice Presidents, under its corporate
seal reproduced thereon attested by its Secretary or one of its Assistant
Secretaries. The signature of any of these officers on the Securities may be
manual or facsimile.
 
     Securities bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.
 
     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities 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. If the
form or terms of the Securities of the series have been established in or
pursuant to one or more Board Resolutions as permitted by Sections 201 and 301,
in authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive such documents as it may reasonably request. The Trustee
shall also be entitled to receive, and (subject to Section 601) shall be fully
protected in relying upon, an Opinion of Counsel stating,
 
          (a) if the form of such Securities has been established by or pursuant
     to a Board Resolution as permitted by Section 201, that such
 
<PAGE>   35
 
                                       26
 303,304
 
     form has been established in conformity with the provisions of this
     Indenture;
 
          (b) if the terms of such Securities have been established by or
     pursuant to a Board Resolution as permitted by Section 301, that such terms
     have been established in conformity with the provisions of this Indenture;
     and
 
          (c) that such Securities, 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, moratorium, reorganization
     and other laws of general applicability relating to or affecting the
     enforcement of creditors' rights, to general equity principles and to such
     other matters as shall be specified in such Opinion of Counsel.
 
Such Opinion of Counsel shall also cover such other matters as the Trustee may
reasonably request. If such form or terms have been so established, the Trustee
shall not be required to authenticate such Securities if the issue of such
Securities pursuant to this Indenture will affect the Trustee's own rights,
duties or immunities under the Securities and this Indenture or otherwise in a
manner which is not reasonably acceptable to the Trustee.
 
     Each Security shall be dated the date of its authentication.
 
     No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder and is entitled to the
benefits of this Indenture.
 
SECTION 304.  Temporary Securities.
 
     Pending the preparation of definitive Securities of any series, the Company
may execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions,
 
<PAGE>   36
 
                                       27
                                                                         304,305
 
substitutions and other variations as the officers executing such Securities may
determine, as evidenced by their execution of such Securities.
 
     If temporary Securities of any series are issued, the Company will cause
definitive Securities of that series to be prepared without unreasonable delay.
After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for definitive Securities of
such series upon surrender of the temporary Securities of such series at the
office or agency of the Company in a Place of Payment for that series, without
charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities of any series the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of the same series of authorized denominations. Until so
exchanged the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.
 
SECTION 305.  Registration, Registration of Transfer and Exchange.
 
     The Company shall cause to be kept at one of its offices or agencies a
register or registers (the register maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby
initially appointed "Security Registrar" for the purpose of registering
Securities and transfers of Securities as herein provided.
 
     Upon surrender for registration of transfer of any Security of any series
at the office or agency in a Place of Payment for that series, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities of the same
series, of any authorized denominations and of a like aggregate principal
amount.
 
     At the option of the Holder, Securities of any series may be exchanged for
other Securities of the same series, of any authorized denominations and of a
like aggregate principal amount, upon surrender of the Securities to be
exchanged at such office or agency. Whenever any Securities are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Holder making the exchange is entitled to
receive.
 
<PAGE>   37
 
                                       28
 305
 
     All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.
 
     Every Security presented or surrendered for registration of transfer or for
exchange shall (if so required by the Company or the Trustee) be duly endorsed,
or be accompanied by a written instrument of transfer in form satisfactory to
the Company and the Security Registrar duly executed, by the Holder thereof or
his attorney duly authorized in writing.
 
     No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.
 
     The Company shall not be required (i) to issue, register the transfer of or
exchange Securities of any series during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section 1103 and ending
at the close of business on the day of such mailing, or (ii) to register the
transfer of or exchange any Security so selected for redemption in whole or in
part, except the unredeemed portion of any Security being redeemed in part.
 
     Notwithstanding any other provisions of this Section, unless and until it
is exchanged in whole or in part for Securities in definitive registered form, a
Global Security 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. The Trustee and the Company shall treat the Depositary or its
nominee as the Holder of Global Securities for all purposes hereof.
 
     If at any time the Depositary for any Securities of a series represented by
one or more Global Securities notifies the Company that it is unwilling or
unable to continue as Depositary for such Securities or if at any time the
Depositary for such Securities shall no longer be eligible under Section 101,
the Company shall appoint a successor Depositary with respect to such
Securities. If a successor Depositary for such Securities is not appointed by
 
<PAGE>   38
 
                                       29
                                                                             305
 
the Company within 90 days after the Company receives such notice or becomes
aware of such ineligibility, the Company's election pursuant to Section 301 that
such Securities be represented by one or more Global Securities shall no longer
be effective and the Company will execute, and the Trustee, upon receipt of a
Company Order for the authentication and delivery of definitive Securities of
such series, will authenticate and deliver, Securities of such series in
definitive registered form without coupons, in any authorized denominations, in
an aggregate principal amount equal to the principal amount of the Global
Security or Securities representing such Securities in exchange for such Global
Security or Securities.
 
     The Company may at any time and in its sole discretion determine that the
Securities of any series issued in the form of one or more Global Securities
shall no longer be represented by a Global Security or Securities. In such event
the Company will execute, and the Trustee, upon receipt of a Company Order for
the authentication and delivery of the definitive Securities of such series,
will authenticate and deliver, Securities of such series in definitive
registered form without coupons, in any authorized denominations, in an
aggregate principal amount equal to the principal amount of the Global Security
or Securities representing such Securities in exchange for such Global Security
or Securities.
 
     If specified by the Company pursuant to Section 301 with respect to
Securities represented by a Global Security, the Depositary for such Global
Security may surrender such Global Security in exchange in whole or in part for
Securities of the same series and tenor in definitive registered form on such
terms as are acceptable to the Company and such Depositary. Thereupon, the
Company shall execute, and the Trustee, upon receipt of a Company Order for the
authentication and delivery of Securities in definitive registered form, shall
authenticate and deliver, without service charge:
 
     (1) to the Person specified by such Depositary a new Security or Securities
of the same series and terms, of any authorized denominations as requested by
such Person, in an aggregate principal amount equal to and in exchange for such
Person's beneficial interest in the Global Security; and
 
     (2) to such Depositary a new Global Security in a denomination equal to the
difference, if any, between the principal amount of the surrendered Global
Security and the aggregate principal amount of Securities authenticated and
delivered pursuant to clause (1) above.
 
<PAGE>   39
 
                                       30
 305,306
 
     Every Person who takes or holds any beneficial interest in a Global
Security agrees that:
 
          (a) the Company and the Trustee may deal with the Depositary as sole
     owner of the Global Security and as the authorized representative of such
     Person;
 
          (b) such Person's rights in the Global Security shall be exercised
     only through the Depositary and shall be limited to those established by
     law and agreement between such Person and the Depositary and/or direct and
     indirect participants of the Depositary; and
 
          (c) the Depositary and its participants make book-entry transfers of
     beneficial ownership among, and receive and transmit distributions of
     principal and interest on the Global Securities to, such Persons in
     accordance with their own procedures.
 
SECTION 306.  Mutilated, Destroyed, Lost and Stolen Securities.
 
     If any mutilated Security is surrendered to the Trustee, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding.
 
     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 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 has been acquired by a bona fide
purchaser, the Company shall execute and upon its request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.
 
     In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.
 
     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.
 
<PAGE>   40

                                                                         306,307
 
     Every new Security of any series issued pursuant to this Section in lieu of
any destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of that series duly issued hereunder.
 
     The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.
 
SECTION 307.  Payment of Interest; Interest Rights Preserved.
 
     Interest on any 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.
 
     Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:
 
          (1) The Company may elect to make payment of any Defaulted Interest to
     the Persons in whose names the Securities of such series (or their
     respective Predecessor Securities) are registered at the close of business
     on a Special Record Date for the payment of such Defaulted Interest, which
     shall be fixed in the following manner. The Company shall notify the
     Trustee in writing of the amount of Defaulted Interest proposed to be paid
     on each Security of such series and the date of the proposed payment, and
     at the same time the Company shall deposit with the Trustee an amount of
     money equal to the aggregate amount proposed to be paid in respect of such
     Defaulted Interest or shall make arrangements satisfactory to the Trustee
     for such deposit prior to the date of the proposed payment, such money when
     deposited to be held in trust for the benefit of the Persons entitled to
     such Defaulted Interest as in this clause provided. Thereupon, the Trustee
     shall fix a Special Record Date for the payment of such Defaulted Interest
     which shall be not more than 15 days and not less than 10 days
 
<PAGE>   41
 
                                       32
 307
 
     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
     Securities of such series at his address as it appears in the Security
     Register, not less than 10 days prior to such Special Record Date. Notice
     of the proposed payment of such Defaulted Interest and the Special Record
     Date therefor having been so mailed, such Defaulted Interest shall be paid
     to the Persons in whose names the Securities of such series (or their
     respective Predecessor Securities) are registered at the close of business
     on such Special Record Date and shall no longer be payable pursuant to the
     following clause (2).
 
          (2) The Company may make payment of any Defaulted Interest on the
     Securities of any series in any other lawful manner not inconsistent with
     the requirements of any securities exchange on which such Securities may be
     listed, and upon such notice as may be required by such exchange, if, after
     notice given by the Company to the Trustee of the proposed payment pursuant
     to this clause, such manner of payment shall be deemed practicable by the
     Trustee.
 
     Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of 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.
 
     In the case of any Security or portion thereof which is surrendered for
conversion after the Regular Record Date next preceding any Interest Payment
Date and on or prior to such next succeeding Interest Payment Date (unless such
Security or portion thereof which is being surrendered for conversion has been
called for redemption on a Redemption Date within such period), interest whose
Stated Maturity is on such Interest Payment Date shall be payable on such
Interest Payment Date notwithstanding such conversion, and such interest
(whether or not punctually paid or duly provided for) 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 such Regular Record Date provided,
however, that such payment of interest shall be subject to the payment to the
Company by the Holder of
<PAGE>   42
 
                                       33
                                                                 307,308,309,310
 
such Security or portion thereof surrendered for conversion (such payment to
accompany such surrender) of an amount equal to the amount of such interest, in
accordance with Section 1502. Except as otherwise provided in the immediately
preceding sentence, in the case of any Security which is converted, interest
whose Stated Maturity is after the date of conversion of such Security shall not
be payable.
 
SECTION 308.  Persons Deemed Owners.
 
     Prior to due presentment of a 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 Security is registered as the owner of such Security
for the purpose of receiving payment of principal of (and premium, if any) and
(subject to Section 307) interest on such Security and for all other purposes
whatsoever, whether or not such Security be overdue, and neither the Company,
the Trustee nor any agent of the Company or the Trustee shall be affected by
notice to the contrary.
 
SECTION 309.  Cancellation.
 
     All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly cancelled by it. The Company may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Securities so delivered shall be promptly cancelled by the
Trustee. No Securities shall be authenticated in lieu of or in exchange for any

by a Company Order the Company shall direct that the cancelled Securities be
returned to it.

SECTION 401.  Satisfaction and Discharge of Indenture.
 
     This Indenture shall cease to be of further effect (except as to any
surviving rights of registration of transfer or exchange of Securities herein
expressly provided for), and the Trustee, at the expense of the Company, shall
execute proper instruments acknowledging satisfaction and discharge of this
Indenture, when
 
          (1) either
 
            (A) all Securities theretofore authenticated and delivered (other
       than (i) Securities which have been destroyed, lost or stolen and which

       for whose payment money has theretofore been deposited in trust or

       Company or discharged from such trust, as provided in Section 1003) have
       been delivered to the Trustee for cancellation; or
 
            (B) all such Securities not theretofore delivered to the Trustee for
       cancellation
 
               (i) have become due and payable, or
 
               (ii) will become due and payable at their Stated Maturity within
          one year, or
 
               (iii) are to be called for redemption within one year under
          arrangements satisfactory to the Trustee for the giving of notice of
          redemption by the Trustee in the name, and at the expense, of the
          Company,
 
       and the Company, in the case of (i), (ii) or (iii) above, has deposited
       or caused to be deposited with the Trustee as trust funds in trust for
       the purpose an amount sufficient to pay and discharge the entire
       indebtedness on such Securities not theretofore delivered to the Trustee
       for cancellation, for principal (and premium, if any) and interest to the
       date of such deposit (in the case of Securities which have become due and

     and an Opinion of Counsel, each stating that all conditions precedent
     herein provided for relating to the satisfaction and discharge of this
     Indenture have been complied with.
 
     Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Trustee to any Authenticating Agent under Section 614 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 402 and the last
paragraph of Section 1003 shall survive.

     Subject to the provisions of the last paragraph of Section 1003, all money
deposited with the Trustee pursuant to Section 401 shall be held in trust and
applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if
any) and interest for whose payment such money has been deposited with the
Trustee.

SECTION 501.  Events of Default.
 
     "Event of Default", wherever used herein with respect to Securities of any
series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):
 
          (1) default in the payment of any interest upon any Security of that
     series when it becomes due and payable, and continuance of such default for
     a period of 60 days; or
 
<PAGE>   45
 
                                       36

          (2) default in the payment of the principal of (or premium, if any,
     on) any Security of that series at its Maturity; or
 
          (3) default in the payment of any sinking fund instalment, when and as
     due by the terms of a Security of that series, and continuance of such
     default for a period of 60 days; or
 
          (4) default in the performance, or breach, of any covenant or warranty
     of the Company in this Indenture (other than a covenant or warranty a
     default in whose performance or whose breach is elsewhere in this Section
     specifically dealt with or which has expressly been included in this
     Indenture solely for the benefit of series of Securities other than that
     series), and continuance of such default or breach for a period of 90 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 that 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;
     or
 
          (5) default by the Company in the payment of any principal of any
     Funded Debt of the Company outstanding in an aggregate principal amount in
     excess of $10,000,000 as and when the same shall become due and payable
     either at maturity, upon redemption, by declaration or otherwise, the
     effect of which default is to cause such Funded Debt to become, or to be
     declared, due prior to its stated maturity unless such default shall be
     cured, by payment or otherwise, within 30 days after the receipt by the
     Company of written notice of such default from the Trustee or from the
     Holders of at least 5% in principal amount of the Outstanding Securities of
     that series; or
 
          (6) the entry by a court having jurisdiction in the premises of (A) a

     Company a bankrupt or insolvent, or approving as properly filed a petition
     seeking reorganization, arrangement, adjustment or composition of or in
     respect of the Company under any applicable Federal or State law, or
     appointing a custodian, receiver, liquidator, assignee, trustee,
     sequestrator or other similar official of the Company or of any substantial
     part of its property, or ordering the winding up or liquidation of its
     affairs, and the continuance of any such

     decree or order for relief or any such other decree or order unstayed and
     in effect for a period of 90 consecutive days; or
 
          (7) the commencement by the Company of a voluntary case or proceeding
     under any applicable Federal or State bankruptcy, insolvency,
     reorganization or other similar law or of any other case or proceeding to
     be adjudicated a bankrupt or insolvent, or the consent by it to the entry
     of a decree or order for relief in respect of the Company in an involuntary
     case or proceeding under any applicable Federal or State bankruptcy,
     insolvency, reorganization or other similar law or to the commencement of
     any bankruptcy or insolvency case or proceeding against it, or the filing
     by it of a petition or answer or consent seeking reorganization or relief
     under any applicable Federal or State law, or the consent by it to the
     filing of such petition or to the appointment of or taking possession by a
     custodian, receiver, liquidator, assignee, trustee, sequestrator or similar
     official of the Company or of any substantial part of its property, or the
     making by it of an assignment for the benefit of creditors, or the
     admission by it in writing of its inability to pay its debts generally as
     they become due, or the taking of corporate action by the Company in
     furtherance of any such action; or
 
          (8) any other Event of Default provided with respect to Securities of
     that series.
 
SECTION 502.  Acceleration of Maturity; Rescission and Annulment.
 
     If an Event of Default with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of that series may declare the principal amount (or, if the Securities of that
series are Original Issue Discount Securities, such portion of the principal
amount as may be specified in the terms of that series) of all of the Securities
of that series to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by Holders), and upon any such declaration
such principal amount (or specified amount) shall become immediately due and
payable.
 
     At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company
 
<PAGE>   47
 
                                       38
 502,503
 
and the Trustee, may rescind and annul such declaration and its consequences if
 
          (1) the Company has paid or deposited with the Trustee a sum
     sufficient to pay
 
            (A) all overdue interest on all Securities of that series,
 
            (B) the principal of (and premium, if any, on) any Securities of
       that series which have become due otherwise than by such declaration of
       acceleration and interest thereon at the rate or rates prescribed
       therefor in such Securities,
 
            (C) to the extent that payment of such interest is lawful, interest
       upon overdue interest at the rate or rates prescribed therefor in such
       Securities, and
 
            (D) all sums paid or advanced by the Trustee hereunder and the
       reasonable compensation, expenses, disbursements and advances of the
       Trustee, its agents and counsel;
 
     and
 
          (2) all 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 513.
 
No such rescission shall affect any subsequent default or impair any right
consequent thereon.
 
SECTION 503.  Collection of Indebtedness and Suits for Enforcement by Trustee.
 
     The Company covenants that if
 
          (1) default is made in the payment of any installment of interest on
     any Security or any deposit of sinking fund payment when such interest or
     deposit becomes due and payable and such default continues for a period of
     60 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, the whole amount then due and payable on
 
<PAGE>   48
 
                                       39
                                                                         503,504
 
such Securities for principal (and premium, if any) and interest and, to the
extent that payment of such interest shall be legally enforceable, interest on
any overdue principal (and premium, if any) and on any overdue interest, at the
rate or rates prescribed therefor in such Securities, and, in addition thereto,
such further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.
 
     If the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Securities, wherever
situated.
 
     If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series by such
appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in this Indenture or in aid of the exercise of any power
granted herein, or to enforce any other proper remedy.
 
SECTION 504.  Trustee May File Proofs of Claim.
 
     In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise,
 
          (i) to file and prove a claim for the whole amount of principal (and
     premium, if any) and interest owing and unpaid in respect of the Securities
     and to file such other papers or documents as may be necessary or advisable
     in order to have the claims of the Trustee
 
<PAGE>   49
 
                                       40
 504,505,506
 
     (including any claim for the reasonable compensation, expenses,
     disbursements and advances of the Trustee, its agents and counsel) and of
     the Holders allowed in such judicial proceeding, and
 
          (ii) to collect and receive any moneys or other property payable or
     deliverable on any such claims and to distribute the same;
 
and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 607.
 
     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.
 
SECTION 505.  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, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Securities in respect of which such judgment has been
recovered.
 
SECTION 506.  Application of Money Collected.
 
     Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium,
if any) or 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 payment of all amounts due the Trustee under Section
     607;
 
          SECOND:  Subject to Article Fourteen, to the payment of the amounts
     then due and unpaid for principal of (and premium, if any) and interest on
     the Securities in respect of which or for the benefit of which such money
     has been collected, ratably, without preference or priority of any kind,
     according to the amounts due and payable on such Securities for principal
     (and premium, if any) and interest, respectively; and
 
          THIRD:  To the Company of any remaining amounts.
 
SECTION 507.  Limitation on Suits.
 
     No Holder of any Security of any series 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) such 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 not less than 25% in principal amount of the
     Outstanding Securities of that series shall have made written request to
     the Trustee to institute proceedings in respect of such Event of Default in
     its own name as Trustee hereunder;
 
          (3) such Holder or Holders have offered to the Trustee reason-
     able indemnity against the costs, expenses and liabilities to be incurred
     in compliance with such request;
 
          (4) the Trustee for 60 days after its receipt of such notice, request
     and offer of indemnity has failed to institute any such proceeding; and
 
          (5) no direction inconsistent with such written request has been given
     to the Trustee during such 60-day period by the Holders of a majority in
     principal amount of the Outstanding Securities of that series;
 
it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any
 
<PAGE>   51
 
                                       42
 507,508,509,510
 
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 such Holders.
 
SECTION 508.  Unconditional Right of Holders to Receive Principal, Premium and
  Interest.
 
     Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of (and premium, if any) and (subject to Section 307)
interest on such Security on the Stated Maturity or Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date) and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.
 
SECTION 509.  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 510.  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
306, no right or remedy herein conferred upon or reserved to the Trustee or to
the Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

SECTION 511.  Delay or Omission Not Waiver.
 
     No delay or omission of the Trustee or of any Holder of any Securities to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article or by law to
the Trustee or to the Holders may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders, as the case may
be.
 
SECTION 512.  Control by Holders.
 
     The Holders of a majority in principal amount of the Outstanding Securities
of any series shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred on the Trustee, with respect to the Securities of
such series, provided that
 
          (1) such direction shall not be in conflict with any rule of law or
     with this Indenture, and
 
          (2) the Trustee may take any other action deemed proper by the Trustee
     which is not inconsistent with such direction.
 
SECTION 513.  Waiver of Past Defaults.
 
     The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any past default hereunder with respect to such
series and its consequences, except a default
 
          (1) in the payment of the principal of (or premium, if any) or
     interest on any Security of such series, or
 
          (2) in respect of a covenant or provision hereof which under Article
     Nine cannot be modified or amended without the consent of the Holder of
     each Outstanding Security of such series affected.
 
     Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.

SECTION 514.  Undertaking for Costs.
 
     All parties to this Indenture agree, and each Holder of any Security by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in principal
amount of the Outstanding Securities of any series, or to any suit instituted by
any Holder for the enforcement of the payment of the principal of (or premium,
if any) or interest on any Security on or after the Stated Maturity or
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date).
 
SECTION 515.  Waiver of Stay or Extension Laws.
 
     The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                  THE TRUSTEE
 
SECTION 601.  Certain Duties and Responsibilities.
 
     (a) Except during the continuance of an Event of Default,
 
          (1) the Trustee undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture, and no implied covenants
     or obligations shall be read into this Indenture against the Trustee; and
 
          (2) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture; but in
     the case of any such certificates or opinions which by any provision hereof
     are specifically required to be furnished to the Trustee, the Trustee shall
     be under a duty to examine the same to determine whether or not they
     conform to the requirements of this Indenture.
 
     (b) In case an Event of Default has occurred and is continuing, the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.
 
     (c) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own wilful misconduct, except that
 
          (1) this Subsection shall not be construed to limit the effect of
     Subsection (a) of this Section;
 
          (2) the Trustee shall not be liable for any error of judgment made in
     good faith by a Responsible Officer, unless it shall be proved that the
     Trustee was negligent in ascertaining the pertinent facts;
 
          (3) the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the direction
     of the Holders of a majority in principal amount of the Outstanding
     Securities of any series, determined as provided in Sec-

     tion 512, relating to the time, method and place of conducting any
     proceeding for any remedy available to the Trustee, or exercising any trust
     or power conferred upon the Trustee, under this Indenture with respect to
     the Securities of such series; and
 
          (4) no provision of this Indenture shall require the Trustee to expend
     or risk its own funds or otherwise incur any financial liability in the
     performance of any of its duties hereunder, or in the exercise of any of
     its rights or powers, if it shall have reasonable grounds for believing
     that repayment of such funds or adequate indemnity against such risk or
     liability is not reasonably assured to it.
 
     (d) Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section.
 
SECTION 602.  Notice of Defaults.
 
     Within 90 days after the occurrence of any default hereunder with respect
to the Securities of any series, the Trustee shall transmit by mail to all
Holders of Securities of such series, as their names and addresses appear in the
Security Register, notice of such default hereunder known to the Trustee, unless
such default shall have been cured or waived; provided, however, that, except in
the case of a default in the payment of the principal of (or premium, if any) or
interest on any Security of such series or in the payment of any sinking fund
instalment with respect to Securities of such series, the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee or a trust committee of directors or Responsible
Officers of the Trustee in good faith determine that the withholding of such
notice is in the interest of the Holders of Securities of such series; and
provided, further, that in the case of any default of the character specified in
Section 501(4) with respect to Securities of such series, no such notice to
Holders shall be given until at least 60 days after the occurrence thereof. For
the purpose of this Section, the term "default" means any event which is, or
after notice or lapse of time or both would become, an Event of Default with
respect to Securities of such series.

SECTION 603.  Certain Rights of Trustee.
 
     Subject to the provisions of Section 601:
 
          (a) the Trustee may rely and shall be protected in acting or
     refraining from acting upon any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or
     document believed by it to be genuine and to have been signed or presented

          (b) any request or direction of the Company mentioned herein shall be
     sufficiently evidenced by a Company Request or Company Order and any
     resolution of the Board of Directors may be sufficiently evidenced by a

          (c) whenever in the administration of this Indenture the Trustee shall
     deem it desirable that a matter be proved or established prior to taking,
     suffering or omitting any action hereunder, the Trustee (unless other
     evidence be herein specifically prescribed) may, in the absence of bad
     faith on its part, rely upon an Officers' Certificate;
 
          (d) the Trustee may consult with counsel and the written advice of
     such counsel or any Opinion of Counsel shall be full and complete
     authorization and protection in respect of any action taken, suffered or
     omitted by it hereunder in good faith and in reliance thereon;
 
          (e) the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request or direction
     of any of the Holders pursuant to this Indenture, unless such Holders shall
     have offered to the Trustee reasonable security or indemnity against the
     costs, expenses and liabilities which might be incurred by it in compliance
     with such request or direction;
 
          (f) the Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or
     document, but the Trustee, in its discretion, may make such further inquiry
     or investigation into such facts or matters as it may see fit, and, if the
     Trustee shall determine to make such further inquiry or investigation, it
     shall be entitled to examine the books, records and premises of the
     Company, personally or by agent or attorney; and

603,604,605,606,607
 
          (g) the Trustee may execute any of the trusts or powers hereunder or
     perform any duties hereunder either directly or by or through agents or
     attorneys and the Trustee shall not be responsible for any misconduct or
     negligence on the part of any agent or attorney appointed with due care by
     it hereunder.
 
SECTION 604.  Not Responsible for Recitals or Issuance of Securities.
 
     The recitals contained herein and in the Securities, except the Trust-
ee's certificates of authentication, shall be taken as the statements of the
Company, and the Trustee or any Authenticating Agent assumes no re-
sponsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture or of the Securities. The
Trustee or any Authenticating Agent shall not be accountable for the use or
application by the Company of Securities or the proceeds thereof.
 
SECTION 605.  May Hold Securities.
 
     The Trustee, any Authenticating Agent, any Paying Agent, any
Security Registrar or any other agent of the Company, in its individual or any
other capacity, may become the owner or pledgee of Securities and, subject to
Sections 608 and 613, may otherwise deal with the Company with the same rights
it would have if it were not Trustee, Authenticating Agent, Paying Agent,
Security Registrar or such other agent.
 
SECTION 606.  Money Held in Trust.
 
     Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed in writing with the Company.

     The Company agrees
 
          (1) to pay to the Trustee from time to time reasonable compensation

     of an express trust);
 
          (2) except as otherwise expressly provided herein, to reimburse the
     Trustee upon its request for all reasonable expenses, disbursements and

<PAGE>   58
 
                                       49
                                                                     607,608,609
 
     with any provision of this Indenture (including the reasonable compensation
     and the expenses and disbursements of its agents and counsel), except any
     such expense, disbursement or advance as may be attributable to its
     negligence or bad faith; and
 
          (3) to indemnify the Trustee for, and to hold it harmless against, any
     loss, liability or expense incurred without negligence or bad faith on its
     part, arising out of or in connection with the acceptance or administration
     of the trust or trusts hereunder, including the costs and expenses of
     defending itself against any claim or liability in connection with the
     exercise or performance of any of its powers or duties hereunder.
 
     As security for the performance of the obligations of the Company under
this Section the Trustee shall have a lien prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of (and premium, if any) or interest on
Securities.
 
SECTION 608.  Disqualification; Conflicting Interests.
 
     Reference is made to Section 310(b) of the Trust Indenture Act. There shall
be excluded from the operation of Section 310(b)(1) of the Trust Indenture Act
this Indenture with respect to the Securities of more than one series.
 
SECTION 609.  Corporate Trustee Required; Eligibility.
 
     There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America, any State thereof or the District of Columbia, authorized under such
laws to exercise corporate trust powers, having a combined capital and surplus
of at least $50,000,000, subject to supervision or examination by Federal or
State authority and having its Corporate Trust Office in the Borough of
Manhattan, The City of New York. If such corporation publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.

SECTION 610.  Resignation and Removal; Appointment of Successor.
 
     (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.
 
     (b) The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 611 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.
 
     (c) The Trustee may be removed at any time with respect to the Securities
of any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Company.
 
     (d) If at any time:
 
          (1) the Trustee shall fail 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 609 and shall
     fail to resign after written request therefor by the Company or by any such
     Holder, or
 
          (3) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property
     shall be appointed or any public officer shall take charge or control of
     the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation,
 
then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (ii) subject to Section 514, 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 shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Company, by a Board Resolution,
shall promptly appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of
such series and that at any time there shall be only one Trustee with respect to
the Securities of any particular series) and shall comply with the applicable
requirements of Section 611. 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 611, 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 611, any
Holder who has been a bona fide Holder of a Security of such series for at least
six months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the appointment of a successor Trustee
with respect to the Securities of such series.
 
     (f) The Company shall give notice of each resignation and each removal of
the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series by mailing
written notice of such event by first-class mail, postage prepaid, to all
Holders of Securities of such series as their names and addresses appear in the
Security Register. Each notice shall include the name of the successor Trustee
with respect to the Securities of such series and the address of its Corporate
Trust Office.
 
SECTION 611.  Acceptance of Appointment by Successor.
 
     (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and
<PAGE>   61
 
                                       52
611
 
such successor Trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts and duties of the retiring
Trustee; but, on the request of the Company or the successor Trustee, such
retiring Trustee shall, upon payment of its charges, execute and deliver an
instrument transferring to such successor Trustee all the rights, powers and
trusts of the retiring Trustee and shall duly assign, transfer and deliver to
such successor Trustee all property and money held by such retiring Trustee
hereunder.
 
     (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
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 Securi-

ties of that or those series to which the appointment of such successor Trustee
relates.
 
     (c) Upon request of any such successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Trustee all such rights, powers and trusts referred to in
paragraph (a) or (b) of this Section, as the case may be.
 
     (d) No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified and eligible under
this Article.
 
SECTION 612.  Merger, Conversion, Consolidation or Succession to Business.
 
     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.
 
SECTION 613.  Preferential Collection of Claims Against Company.
 
     Reference is made to Section 311 of the Trust Indenture Act. For purposes
of Section 311(b),
 
          (1) the term "cash transaction" means any transaction in which full
     payment for goods or securities sold is made within seven days after
     delivery of the goods or securities in currency or in checks or other
     orders drawn upon banks or bankers and payable upon demand;
 
          (2) the term "self-liquidating paper" means any draft, bill of
     exchange, acceptance or obligation which is made, drawn, negotiated or
     incurred by the Company for the purpose of financing the purchase,
     processing, manufacture, shipment, storage or sale of goods, wares or
     merchandise and which is secured by documents evidencing title to,
     possession of, or a lien upon, the goods, wares or merchandise or the
 
<PAGE>   63
 
                                       54
613,614
 
     receivables or proceeds arising from the sale of the goods, wares or
     merchandise previously constituting the security, provided the security is
     received by the Trustee simultaneously with the creation of the creditor
     relationship with the Company arising from the making, drawing, negotiating
     or incurring of the draft, bill of exchange, acceptance or obligation.
 
SECTION 614.  Appointment of Authenticating Agent.
 
     At any time when any of the Securities remain Outstanding 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 exchange, registration of
transfer or partial redemption thereof or pursuant to Section 306, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business
under the laws of the United States of America, any State thereof or the
District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined capital and surplus of not less than $50,000,000 and subject
to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.
 
     Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent,
<PAGE>   64
 
                                       55
                                                                             614
 
shall continue to be an Authenticating Agent, provided such corporation shall be
otherwise eligible under this Section, without the execution or filing of any
paper or any further act on the part of the Trustee or the Authenticating Agent.
 
     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof 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 may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders of
Securities of the series with respect to which such Authenticating Agent will
serve, as their names and addresses appear in the Security Register. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.
 
     The Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payments, subject to the provisions
of Section 607.
 
     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 the Trustee's certificate of authentication, an alternate
certificate of authentication in the following form:

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

     The Company will furnish or cause to be furnished to the Trustee
 
          (a) semi-annually, not more than 15 days after each Regular Record
     Date, a list, in such form as the Trustee may reasonably require, of the
     names and addresses of the Holders as of such Regular Record Date, and

     (b) If three or more Holders (herein referred to as "applicants") apply in
writing to the Trustee, and furnish to the Trustee reasonable proof that each
such applicant has owned a Security for a period of at least six months
preceding the date of such application, and such application states that the
applicants desire to communicate with other Holders with respect to their rights
under this Indenture or under the Securities and is accompanied by a copy of the
form of proxy or other communication which such applicants propose to transmit,
then the Trustee shall, within five business days after the receipt of such
application, at its election, either
 
          (i) afford such applicants access to the information preserved at the
     time by the Trustee in accordance with Section 702(a), or
 
          (ii) inform such applicants as to the approximate number of Holders
     whose names and addresses appear in the information preserved at the time
     by the Trustee in accordance with Section 702(a), and as to the approximate
     cost of mailing to such Holders the form of proxy or other communication,
     if any, specified in such application.
 
     If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Holder whose name and address appear in the information preserved
at the time by the Trustee in accordance with Section 702(a) a copy of the form
of proxy or other communication which is specified in such request, with
reasonable promptness after a tender to the Trustee of the material to be mailed
and of payment, or provision for the payment, of the reasonable expenses of
mailing, unless within five days after such tender the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interest of the Holders
or would be in violation of applicable law. Such written statement shall specify
the basis of such opinion. If the Commission, after opportunity for a hearing
upon the objections specified in the written statement so filed, shall enter an
order refusing to sustain any of such objections or if, after the entry of an
order sustaining one or more of such objections, the Commission shall find,
after notice and opportunity for hearing, that all the objections so sustained
have been met and shall enter an order so declaring, the Trustee shall mail
copies of such material to all such Holders with reasonable promptness after the
entry of such order and the renewal of such tender; otherwise the Trustee shall
be relieved of any obligation or duty to such applicants respecting their
application.

disclosure of any such information as to the names and addresses of the Holders
in accordance with Section 702(b), regardless of the source from which such
information was derived, and that the Trustee shall not be held accountable by
reason of mailing any material pursuant to a request made under Section 702(b).

is merged or to which such conveyance, transfer or lease is made shall succeed
to, and be substituted for, and may exercise every right and power of, the
Company under this Indenture with the same effect as if such successor person
had been named as the Company herein, and thereafter, except in the case of a
lease to another Person, the predecessor person shall be relieved of all
obligations and covenants under this Indenture and the Securities.

     series) or to surrender any right or power herein conferred upon the
     Company; or
 
          (3) to add any additional Events of Default to all or any series of
     Securities; or
 
          (4) to add to or change any of the provisions of this Indenture to

     and with or without interest coupons; or
 
          (5) to change or eliminate any of the provisions of this Indenture,

     of such provision; or

     questions arising under this Indenture which shall not adversely affect the
     interests of the Holders of Securities of any series in any material
     respect.
 
SECTION 902.  Supplemental Indentures with Consent of Holders.
 
     With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company, when authorized by a Board Resolution, and the Trustee may
enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the rights of the
Holders of Securities of such series under this Indenture; provided, however,
that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Security affected thereby,
 
          (1) change the Stated Maturity of the principal of, or any instalment
     of principal of or interest on, any Security, or reduce the principal
     amount thereof or the rate of interest thereon or any premium payable upon

     Original Issue Discount Security that would be due and payable upon a
     declaration of acceleration of the Maturity thereof pursuant to Section
     502, or change any Place of Payment where, or the coin or currency in
     which, any Security or any premium or the interest thereon is payable, or
     impair the right to institute suit for the enforcement of any such payment
     on or after the Stated Maturity thereof (or, in the case of redemption, on
     or after the Redemption Date), or adversely affect the right to convert any
     security as provided in Article Fifteen or modify the provisions of this
     Indenture with respect to the subordination of the Securities in a manner
     adverse to the Holders, or
 
          (2) reduce the percentage in principal amount of the Outstanding
     Securities of any series, the consent of whose Holders is required for any
     such supplemental indenture, or the consent of whose Holders is required
     for any waiver (of compliance with certain provisions of this Indenture or
     certain defaults hereunder and their consequences) provided for in this
     Indenture, or
 
          (3) modify any of the provisions of this Section or Section 513,
     except to increase any such percentage or to provide that certain other

     provisions of this Indenture cannot be modified or waived without the
     consent of the Holder of each Outstanding Security affected thereby,
     provided, however, that this clause shall not be deemed to require the
     consent of any Holder with respect to changes in the references to "the
     Trustee" and concomitant changes in this Section, or the deletion of this
     proviso, in accordance with the requirements of Sections 611(b) and 901(8).
 
A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture 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 shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.
 
SECTION 903.  Execution of Supplemental Indentures.
 
     In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 601) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture. The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.
 
SECTION 904.  Effect of Supplemental Indentures.
 
     Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.
 
SECTION 905.  Conformity with Trust Indenture Act.
 
     Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

SECTION 906.  Reference in Securities to Supplemental Indentures.
 
     Securities of any series authenticated and delivered after the execution of
any supplemental indenture pursuant to this Article may, and shall if required
by the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company shall so determine,
new Securities of any series so modified as to conform, in the opinion of the
Trustee and the Company, to any such supplemental indenture may be prepared and
executed by the Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities of such series.
 
SECTION 907.  Subordination Unimpaired.
 
     No supplemental indenture executed pursuant to this Article shall adversely
affect the rights of any holder of Senior Indebtedness under Article Fourteen
without the consent of such holder.

                                   COVENANTS
 
SECTION 1001.  Payment of Principal, Premium and Interest.
 
     The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of (and premium,
if any) and interest on the Securities of that series in accordance with the
terms of the Securities and this Indenture.
 
SECTION 1002.  Maintenance of Office or Agency.
 
     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, where Securities may be surrendered
for conversion and where notices and demands to or upon the Company in respect
of the Securities of that series and this Indenture may be served. The Company
will give prompt written notice to the Trustee of the location, and any change
in the location, of such office or agency. If at any time the Company shall fail
to maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust Office of the Trustee, and
the Company
 
<PAGE>   73
 
                                       64
1002,1003
 
hereby appoints the Trustee as its agent to receive all such presentations,
surrenders, notices and demands.
 
     The Company may also from time to time designate one or more other offices
or agencies where the Securities of one or more series may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency
in each Place of Payment for Securities of any series for such purposes. The
Company will give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency.
 
SECTION 1003.  Money for Securities Payments to Be Held in Trust.
 
     If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities, it will, on or before each due date of the
principal of (and 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 (and premium, if any) or interest
so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and will promptly notify the Trustee of its
action or failure so to act.
 
     Whenever the Company shall have one or more Paying Agents for any series of
Securities, it will, prior to each due date of the principal of (and premium, if
any) or interest on any Securities of that series, deposit with a Paying Agent a
sum sufficient to pay the principal (and premium, if any) or interest so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Company will promptly notify the Trustee of its action or
failure so to act. For purposes of this Section, should a due date for principal
of (and premium, if any), interest on or sinking fund payment with respect to
any series of Securities not be on a Business Day, such payment shall be due on
the next Business Day without any interest for the period from the due date
until such Business Day.
 
     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:
 
<PAGE>   74
 
                                       65                                  1003
 
          (1) hold all sums held by it for the payment of the principal of (and
     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 (and premium, if any) or interest on the Securities of
     that series; and
 
          (3) at any time during the continuance of any such default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent.
 
     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which 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 the principal of (and premium, if any)
or interest on any Security of any series and remaining unclaimed for one year
after such principal (and 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
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 Borough of Manhattan, The City of New York, 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 mailing or publication, any
unclaimed balance of such money then remaining will be repaid to the Company.

SECTION 1004.  Corporate Existence
 
     Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence, rights (charter and statutory) and franchises; provided, however,
that the Company shall not be required to preserve any such right or franchise
if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company and that the loss
thereof is not disadvantageous in any material respect to the Holders.
 
SECTION 1005.  Statement by Officers as to Default.
 
     Annually, within 120 days after the close of each fiscal year beginning
with the fiscal year ending December 31, 1995, the Company will deliver to the
Trustee a brief certificate (which shall not be deemed to be an Officers'
Certificate within the meaning of this Indenture and need not conform with any
of the provisions of Section 102) from the principal executive officer,
principal financial officer or principal accounting officer of the Company as to
his or her knowledge of the Company's compliance (without regard to any period
of grace or requirement of notice provided herein) with all conditions and
covenants under the Indenture, or, if there has been a default in the
fulfillment of any such obligation, specifying each such default known to him or
her and the nature thereof.

     If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 45 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions (equal to the minimum authorized denomination for
Securities of that series or any integral multiple thereof) of the principal
amount of Securities of such series of a denomination larger than the minimum
authorized denomination for Securities of that series.
 
     The Trustee shall promptly notify the Company in writing of the Securities
selected for redemption and, in the case of any Securities selected for partial
redemption, the principal amount thereof to be redeemed.
 
     For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion
of the principal amount of such Securities which has been or is to be redeemed.
 
SECTION 1104.  Notice of Redemption.
 
     Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 15 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at his address appearing in the
Security Register.
 
     All notices of redemption shall state:
 
          (1) the Redemption Date,
 
          (2) the Redemption Price,
 
          (3) if less than all the Outstanding Securities of any series are to
     be redeemed, the identification (and, in the case of partial redemption,
     the principal amounts) of the particular Securities to be redeemed,

1104,1105,1106                         68
 
          (4) that on the Redemption Date the Redemption Price will become due
     and payable upon each such Security to be redeemed and, if applicable, that
     interest thereon will cease to accrue on and after said date,
 
          (5) the place or places where such Securities are to be surrendered
     for payment of the Redemption Price,
 
          (6) that the redemption is for a sinking fund, if such is the case,
     and
 
          (7) any other information relevant to any particular series.
 
     Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.
 
SECTION 1105.  Deposit of Redemption Price.
 
     On or prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date.
 
SECTION 1106.  Securities Payable on Redemption Date.
 
     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security 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 instalments of interest whose
Stated Maturity is on or prior to the Redemption Date shall be payable to the
Holders of such Securities, or one or more Predecessor Securities, registered as
such at the close of business on the relevant Record Dates according to their
terms and the provisions of Section 307.
 
     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal (and premium, if any)
 

<PAGE>   78
 
                                       69                   1106,1107,1201,1202
 
shall, until paid, bear interest from the Redemption Date at the rate prescribed
therefor in the Security.
 
SECTION 1107.  Securities Redeemed in Part.
 
     Any Security which is to be redeemed only in part shall be surrendered at a
Place of Payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Security without service
charge, a new Security or Securities of the same series, of any authorized
denomination as requested by such Holder, in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Security so
surrendered.

                                 SINKING FUNDS
 
SECTION 1201.  Applicability of Article.
 
     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.
 
     The minimum amount of any sinking fund payment provided for by the terms of
Securities of any series is herein referred to as a "mandatory sinking fund
payment", and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment". 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 1202. 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 1202.  Satisfaction of Sinking Fund Payments with Securities.
 
     The Company (1) may deliver Outstanding Securities of a series (other than
any previously called for redemption) and (2) may apply as a credit Securities
of a series which have been acquired or 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 or which
have been converted into Common Stock or otherwise acquired by the Company
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 1203.  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 Securities of that series
pursuant to Section 1202 and will also deliver to the Trustee any Securities to
be so delivered. Not less than 45 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 1103 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 1104. Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Sections 1106 and 1107.

SECTION 1302.  Defeasance and Discharge.
 
     Upon the Company's exercise of the above option applicable to this Section,
the Company shall be deemed to have been discharged from its obligations with
respect to the Outstanding Securities of such series on the date the conditions
set forth below 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 the Outstanding Securities of
such series and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following which shall survive until
otherwise terminated or discharged hereunder:  (A) the rights of Holders of
Outstanding Securities of such series to receive, solely from the trust fund
described in Section 1304 and as more fully set forth in such Section, payments
in respect of the principal of (and premium, if any) and interest on such
Securities when such payments are due, (B) the Company's obligations with
respect to such Securities under Sections 304, 305, 306, 1002 and 1003, (C) the

     of Section 609 who shall agree to comply with the provisions of this
     Article Thirteen applicable to it) as trust funds in trust for the purpose
     of making the following payments, specifically pledged as security for, and
     dedicated solely to, the benefit of the Holders of such Securities, (A)
     money in an amount, or (B) U.S. Government Obligations which through the
     scheduled payment of principal and interest in respect thereof in
     accordance with their terms will provide, not later than one day before the
     due date of any payment, money in an amount, or (C) a combination thereof,
     sufficient, in the opinion of a nationally recognized firm of independent
     public accountants expressed in a written certification thereof delivered
     to the Trustee, to pay and discharge, and which shall be applied by the
     Trustee (or other qualifying trustee) to pay and discharge, (i) the
     principal of (and premium, if

1303                                       72

     interest on the Outstanding Securities of such series on the Stated
     Maturity of such principal or installment of principal or interest and (ii)
     any mandatory sinking fund payments or analogous payments applicable to the
     Outstanding Securities of such series on the day on which such payments are
     due and payable in accordance with the terms of this Indenture and of such
     Securities. For this purpose, "U.S. Government Obligations" means
     securities that are (x) direct obligations of the United States of America
     for the payment of which its full faith and credit is pledged or (y)
     obligations of a Person controlled or supervised by and acting as an agency
     or instrumentality of the United States of America, for the payment of
     which its full faith and credit is pledged, which, in either case, are not
     callable or redeemable at the option of the issuer thereof, and shall also
     include a depository receipt issued by a bank (as defined in Section
     3(a)(2) of the Securities Act of 1933, as amended) as custodian with
     respect to any such U.S. Government Obligation or a specific payment of
     principal of or interest on any such U.S. Government Obligation held by
     such custodian for the account of the holder of such depository receipt,
     provided that (except as required by law) such custodian is not authorized
     to make any deduction from the amount payable to the holder of such
     depository receipt from any amount received by the custodian in respect of
     the U.S. Government Obligation or the specific payment of principal of or
     interest on the U.S. Government Obligation evidenced by such depository
     receipt.
 
          (2) No Event of Default or event which with notice or lapse of time or
     both would become an Event of Default with respect to the Securities of
     such series shall have occurred and be continuing on the date of such
     deposit.
 
          (3) Such defeasance shall not cause the Trustee for the Securities of
     such series to have a conflicting interest as defined in Section 310(b) of
     the Trust Indenture Act with respect to any securities of the Company.
 
          (4) Such defeasance shall not result in a breach or violation of, or
     constitute a default under this Indenture or any other agreement or
     instrument to which the Company is a party or by which it is bound.
 
          (5) Such defeasance shall not cause any Securities of such series then
     listed on any registered national securities exchange under the Securities
     Exchange Act of 1934, as amended, to be delisted.

                                       73                              1303,1304
 
          (6) Such defeasance shall be effected in compliance with any
     additional terms, conditions or limitations which may be imposed on the
     Company in connection therewith pursuant to Section 301.
 
          (7) The Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent provided for relating to the defeasance under Section 1302 have
     been complied with.
 
     Notwithstanding the foregoing, if an Event of Default specified in
Subsection 501(5) or 501(6), or an event which with lapse of time would become
such an Event of Default, shall occur during the period ending on the 91st day
after the date of the deposit referred to in Clause (1) or, if longer, ending on
the day following the expiration of the longest preference period applicable to
the Company in respect of such deposit, then, effective upon such occurrence,
the defeasance and such deposit shall be rescinded and annulled, and the
Company, the Trustee and the Holders of the Securities of such series shall be
restored to their former positions.
 
SECTION 1304.  Deposited Money and U.S. Government Obligations to be
  Held in Trust; Other Miscellaneous Provisions.
 
     Subject to the provisions of the last paragraph of Section 1003, all money
and U.S. Government Obligations (including the proceeds thereof) deposited with
the Trustee (or other qualifying trustee -- collectively, for purposes of this
Section 1304, the "Trustee") pursuant to Section 1303 in respect of the
Outstanding Securities of such series shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent), to the Holders of such
Securities, of all sums due and to become due thereon in respect of principal
(and premium, if any) and interest, but such money need not be segregated from
other funds except to the extent required by law.
 
     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1303 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of the Outstanding Securities of such series.
 
     Anything in this Article Thirteen to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon

in Section 1303 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof

be required to be deposited to effect an equivalent defeasance.

                          SUBORDINATION OF SECURITIES
 
Section 1401.  Securities Subordinate to Senior Indebtedness.
 
     The Company covenants and agrees, and each Holder of a Security, by his
acceptance thereof, whether upon original issue or upon transfer or assignment,
likewise covenants and agrees, that, to the extent and in the manner hereinafter
set forth, the payment of the principal of (and premium, if any) and interest on
each and all of the Securities is hereby expressly made subordinate and subject
in right of payment to the prior payment in full of all Senior Indebtedness.
 
SECTION 1402.  Payment Over of Proceeds Upon Dissolution, Etc., of
  Company.
 
     In the event of any insolvency or bankruptcy case or proceeding, or any
receivership, liquidation, reorganization or other similar case or proceeding in
connection therewith, relative to the Company or to its creditors, as such, or
to its property, and in the event of any voluntary liquidation, dissolution or
other winding up of the Company, whether or not involving insolvency or
bankruptcy, then the holders of Senior Indebtedness shall be entitled to receive
payment in full of all amounts due or to become due on or in respect of all
Senior Indebtedness before the Holders of the Securities are entitled to receive
any payment on account of principal of (or premium, if any) or interest on the
Securities, and to that end (but subject to the power of a court of competent
jurisdiction to make other equitable provision reflecting the rights conferred
by the provisions of this Article upon the Senior Indebtedness and the holders
thereof with respect to the Securities and the Holders thereof by a lawful plan
of reorganization under applicable bankruptcy law) the holders of Senior
Indebtedness shall be entitled to receive any payment or distribution of any
kind or character, whether in cash, property or securities, which may be payable
or deliverable in any such case or proceeding in respect of the Securities,
except securities of the Company
 

<PAGE>   84
 
                                       75                                  1402
 
which are subordinate and subject in right of payment to the prior payment in
full of all Senior Indebtedness then outstanding.
 
     In the event that, notwithstanding the foregoing, the Trustee or the Holder
of any Security shall have received any payment or distribution of any kind or
character, whether in cash, property or securities (other than as aforesaid),
before all Senior Indebtedness is paid in full or payment thereof provided for,
and if such fact shall then have been made known to the Trustee or, as the case
may be, such Holder, then and in such event such payment or distribution shall
be paid over or delivered forthwith to the trustee in bankruptcy, receiver,
liquidating trustee, custodian, agent or other Person making payment or
distribution of assets or securities of the Company for application to the
payment of all Senior Indebtedness remaining unpaid, to the extent necessary to
pay all Senior Indebtedness in full, after giving effect to any concurrent
payment or distribution to or for the holders of Senior Indebtedness.
 
     In the event that any Securities are declared due and payable before their
Stated Maturity because of the occurrence of an Event of Default (under
circumstances when the provisions of the foregoing paragraph shall not be
applicable), the holders of the Senior Indebtedness outstanding at the time such
Securities become due and payable because of such occurrence of an Event of
Default shall be entitled to receive payment in full of all amounts due or to
become due or in respect of all Senior Indebtedness before the Holders of the
Securities are entitled to receive any payment on account of the principal of
(or premium, if any) or interest on the Securities.
 
     The consolidation of the Company with, or the merger of the Company into,
another corporation or the liquidation or dissolution of the Company following
the conveyance or transfer of its properties and assets substantially as an
entirety to another corporation upon the terms and conditions set forth in
Article Eight shall not be deemed a dissolution, winding up, liquidation or
reorganization for the purposes of this Section if such other corporation shall,
as a part of such consolidation, merger, conveyance or transfer, comply with the
conditions set forth in Article Eight.
 
     Nothing in this Article shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 607.

SECTION 1403.  No Payment When Senior Indebtedness in Default in Payment.
 
     (a) In the event and during the continuation of any default in the payment
of principal of (or premium, if any) or interest on any Senior Indebtedness
beyond any applicable period of grace, unless and until such default in payment
shall have been cured or waived or shall have ceased to exist, or (b) in the
event any judicial proceeding shall be pending with respect to any such default
in payment, then no payment of principal of (or premium, if any) or interest on
the Securities shall be made by the Company; provided, however, that nothing in
this Section shall prevent the satisfaction of any sinking fund payment in
accordance with Article Twelve by means of Securities redeemed or acquired prior
to such default in payment or by means of conversion Securities.
 
SECTION 1404. Payment Permitted if No Default.
 
     Nothing contained in this Article or elsewhere in this Indenture or in any
of the Securities shall prevent (a) the Company, at any time except during the
pendency of any case or proceeding, or any dissolution or other winding up
referred to in Section 1402 or under the other conditions described in Section
1402 or the conditions described in Section 1403 from making payments at any
time of principal of (and premium, if any) or interest on the Securities, or (b)
the application by the Trustee of any money deposited with it hereunder to the
payment of or on account of the principal of (and premium, if any) or interest
on the Securities if, at the time of such application, the Trustee did not have
knowledge that such payment would have been prohibited by the provisions of this
Article.
 
SECTION 1405.  Subrogation to Rights of Holders of Senior Indebtedness.
 
     Subject to the payment in full of all Senior Indebtedness, the Holders of
the Securities shall be subrogated (to the extent of the payments or
distributions made to the holders of such Senior Indebtedness pursuant to the
provisions of this Article) to the rights of the holders of such Senior
Indebtedness to receive payments or distributions from the Company applicable to
the Senior Indebtedness until the principal of (and premium, if any) and
interest on the Securities shall be paid in full. For purposes of such
subrogation, no payments or distributions to the holders of the Senior
Indebtedness to which the Holders of the Securities or the Trustee would be
entitled except for the provisions of this Article, and no payments over
pursuant to the provisions of this Article to the holders of Senior Indebted-

ness by Holders of the Securities or the Trustee, shall, as between the Company,
its creditors other than holders of Senior Indebtedness, and the Holders of the
Securities, be deemed to be a payment or distribution by the Company to or on
account of the Senior Indebtedness.
 
SECTION 1406.  Provisions Solely to Define Relative Rights.
 
     The provisions of this Article are and are intended solely for the purpose
of defining the relative rights of the Holders of the Securities, on the one
hand, and the holders of Senior Indebtedness, on the other hand. Nothing
contained in this Article or elsewhere in this Indenture or in the Securities is
intended to or shall impair, as between the Company and the Holders of the
Securities, the obligation of the Company, which is absolute and unconditional,
to pay to the Holders of the Securities the principal of (and premium, if any)
and interest on the Securities as and when the same shall become due and payable
in accordance with their terms, or is intended to or shall effect the relative
rights against the Company of the Holders of the Securities and creditors of the
Company other than the holders of Senior Indebtedness, nor shall anything herein
or therein prevent the Trustee or the Holder of any Security from exercising all
remedies otherwise permitted by applicable law upon default under this
Indenture, subject to the rights, if any, under this Article of the holders of
Senior Indebtedness to receive cash, property or securities of the Company
otherwise payable or deliverable to the Trustee or such Holder.
 
SECTION 1407.  Trustee to Effectuate Subordination.
 
     Each Holder of a Security by his acceptance thereof, whether upon original
issue or upon transfer or assignment, authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to effectuate the
subordination provided in this Article and appoints the Trustee his
attorney-in-fact for any and all such purposes.
 
SECTION 1408.  No Waiver of Subordination Provisions.
 
     No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such holder, or by any
noncompliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof any such holder may have or be
otherwise charged with.

1408,1409                              78
 
     Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Indebtedness may, at any time and from time to time, without
the consent of or notice to the Holders of the Securities, without incurring
responsibility to the Holders of the Securities and without impairing or
releasing the subordination provided in this Article or the obligations of the
Holders of the Securities to the holders of the Senior Indebtedness, do any one
or more of the following: (i) change the manner, place or terms of payment of,
or renew or alter, Senior Indebtedness, or otherwise amend or supplement in any
manner Senior Indebtedness or any instrument evidencing the same or any
agreement under which Senior Indebtedness is outstanding; (ii) sell, exchange,
release or otherwise deal with any property pledged, mortgaged or otherwise
securing Senior Indebtedness; (iii) release any Person liable in any manner for
the collection of Senior Indebtedness; and (iv) exercise or refrain from
exercising any rights against the Company and any other Person.
 
SECTION 1409.  Notice to Trustee.
 
     The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment of money to
or by the Trustee in respect of the Securities pursuant to the provisions of
this Article. Notwithstanding the provisions of this Article or any other
provision of this Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts which would prohibit the making of any payment to or
by the Trustee in respect of the Securities pursuant to the provisions of this
Article, unless and until a responsible officer of the Trustee shall have
received at its Corporate Trust Office written notice thereof from the Company
or a holder or holders of Senior Indebtedness or from any trustee therefor; and,
prior to the receipt of any such written notice, the Trustee, subject to the
provisions of Section 601, shall be entitled in all respects to assume that no
such facts exist.
 
     Subject to the provisions of Section 601, the Trustee shall be entitled to
rely on the delivery to it of a written notice by a Person representing himself
to be a holder of Senior Indebtedness (or a trustee on behalf of such holder) to
establish that such notice has been given by a holder of Senior Indebtedness or
a trustee on behalf of any such holder. In the event that the Trustee determines
in good faith that further evidence is required with respect to the right of any
Person as a holder of Senior Indebtedness to participate in any payment or
distribution pursuant to this Article, the Trustee may request such Person to
furnish evidence to the reasonable satisfaction of the Trustee as to the amount
of Senior Indebtedness held by

                                       79                   1409,1410,1411,1501
 
such Person, the extent to which such Person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
Person under this Article, and if such evidence is not furnished, the Trustee
may defer any payment to such Person pending judicial determination as to the
right of such Person to receive such payment.
 
SECTION 1410.  Reliance on Certificate of Liquidating Agent.
 
     Upon any payment or distribution referred to in this Article, the Trustee,
subject to the provisions of Section 601, and the Holders of the Securities
shall be entitled to rely upon any order or decree entered by any court of
competent jurisdiction in which such insolvency, bankruptcy, receivership,
liquidation reorganization, dissolution, winding up or similar case or
proceeding is pending, or a certificate of the trustee in bankruptcy,
liquidating trustee, custodian, receiver, assignee for the benefit of creditors,
agent or other Person making such payment or distribution, delivered to the
Trustee or to the Holders of Securities, for the purpose of ascertaining the
Persons entitled to participate in such distribution, the holders of the Senior
Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article.
 
SECTION 1411.  Trustee Not Fiduciary for Holders of Senior Indebtedness.
 
     The Trustee shall not be deemed to owe any fiduciary duty to the holders of
Senior Indebtedness. The Trustee's duties to holders of Senior Indebtedness are
limited to those specifically set forth in this Indenture and no implied
covenants or obligations shall be read into this Indenture against the Trustee.
The Trustee shall not be liable to any such holders if it shall in good faith
mistakenly pay over or distribute to Holders of Securities or to the Company or
to any other Person cash, property or securities to which any holders of Senior
Indebtedness shall be entitled by virtue of this Article or otherwise.
 
                                ARTICLE FIFTEEN
 
                            CONVERSION OF SECURITIES
 
SECTION 1501.  Applicability; Conversion Privilege and Conversion Price.
 
     Securities of any series which are convertible into Common Stock shall be
convertible in accordance with their terms and (except as otherwise
 
                                                             
<PAGE>   89
 
1501,1502                              80
 
specified as contemplated by Section 301 for Securities of any series) in
accordance with this Article.
 
     Subject to and upon compliance with the provisions of this Article Fifteen,
at the option of the Holder thereof, any Security or any portion of the
principal amount thereof which is $1,000 or an integral multiple of $1,000 may
be converted at the principal amount thereof, (or, with respect to Original
Issue Discount Securities, at the amount determined pursuant to Section 301), or
of such portion thereof, into fully paid and nonassessable shares (calculated as
to each conversion to the nearest one-hundredth of a share) of Common Stock, at
the Conversion Price, determined as hereinafter provided, in effect at the time
of conversion. Such conversion right shall expire at the close of business on
the date specified for Securities of such Series. In case a Security or portion
thereof is called for redemption, such conversion right in respect of the
Security or portion so called shall expire at the close of business on the
Redemption Date, unless the Company defaults in making the payment due upon
redemption.
 
     The price at which shares of Common Stock shall be delivered upon
conversion (herein called the "Conversion Price") shall be the price specified
in relation to Securities of such series pursuant to Section 301. The Conversion
Price shall be adjusted in certain instances as provided in paragraphs (1), (2),
(3), (4) and (7) of Section 1504.
 
SECTION 1502.  Exercise of Conversion Privilege.
 
     In order to exercise the conversion privilege, the Holder of any Security
to be converted shall surrender such Security, together with the conversion
notice duly executed, at any office or agency of the Company maintained for that
purpose pursuant to Section 1002, accompanied by written notice to the Company
at such office or agency that the Holder elects to convert such Security or, if
less than the entire principal amount thereof is to be converted, the portion
thereof to be converted. Securities or portions thereof surrendered for
conversion during the period from the close of business on any Regular Record
Date next preceding any Interest Payment Date to the opening of business on such
Interest Payment Date shall (unless such Securities or portions thereof have
been called for redemption on a Redemption Date within such period) be
accompanied by payment to the Company or its order, in New York Clearing House
funds or other funds acceptable to the Company, of an amount equal to the
interest payable on such Interest Payment Date on the principal amount of
Securities or portions thereof being surrendered for conversion. No payment or
 

<PAGE>   90
 
                                       81                        1502,1503,1504
 
adjustment shall be made upon any conversion on account of any interest accrued
on the Securities surrendered for conversion or, except as provided in Section
1504, on account of any dividends on the Common Stock issued upon conversion.
 
     Securities shall be deemed to have been converted immediately prior to the
close of business on the day of surrender of such Securities for conversion in
accordance with the foregoing provisions, and at such time the rights of the
Holders of such Securities as Holders shall cease, and the Person or Persons
entitled to receive the Common Stock issuable upon conversion shall be treated
for all purposes as the record holder or holders of such Common Stock at such
time. As promptly as practicable on or after the conversion date, the Company
shall issue and shall deliver at such office or agency a certificate or
certificates for the number of full shares of Common Stock issuable upon
conversion, together with payment in lieu of any fraction of a share, as
provided in Section 1503.
 
     In the case of any Security which is converted in part only, upon such
conversion the Company shall execute and the Trustee shall authenticate and
deliver to the Holder thereof, at the expense of the Company, a new Security or
Securities of authorized denominations in aggregate principal amount equal to
the unconverted portion of the principal amount of such Security.
 
SECTION 1503.  Fractions of Shares.
 
     No fractional shares of Common Stock shall be issued upon conversion of
Securities. If more than one Security shall be surrendered for conversion at one
time by the same Holder, the number of full shares which shall be issuable upon
conversion thereof shall be computed on the basis of the aggregate principal
amount of the Securities (or specified portions thereof) so surrendered. Instead
of any fractional share of Common Stock which would otherwise be issuable upon
conversion of any Security or Securities (or specified portions thereof), the
Company shall pay a cash adjustment in respect of such fraction in an amount
equal to the same fraction of the market price (determined as provided in the
last sentence of paragraph 6 of Section 1504) at the close of business on the
day of conversion.
 
SECTION 1504.  Adjustment of Conversion Price.
 
     (1) In case the Company shall pay or make a dividend or other distribution
on any class of capital stock of the Company in Common Stock, the Conversion
Price in effect at the opening of business on the day
 
                                                                  
<PAGE>   91
 
1504                                       82
 
following the date fixed for the determination of stockholders entitled to
receive such dividend or other distribution shall be reduced by multiplying such
Conversion Price by a fraction of which the numerator shall be the number of
shares of Common Stock outstanding at the close of business on the date fixed
for such determination and the denominator shall be the sum of such number of
shares and the total number of shares constituting such dividend or other
distribution, such reduction to become effective immediately after the opening
of business on the day following the date fixed for such determination. For the
purposes of this paragraph (1), the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Company but
shall include shares issuable in respect of scrip certificates issued in lieu of
fractions of shares of Common Stock. The Company will not pay any dividend or
make any distribution on shares of Common Stock held in the treasury of the
Company.
 
     (2) In case the Company shall issue rights or warrants to all holders of
its Common Stock entitling them to subscribe for or purchase shares of Common
Stock at a price per share less than the market price (determined as provided in
paragraph (6) of this Section) of the Common Stock on the date fixed for the
determination of stockholders entitled to receive such rights or warrants, the
Conversion Price in effect at the opening of business on the day following the
date fixed for such determination shall be reduced by multiplying such
Conversion Price by a fraction of which the numerator shall be the number of
shares of Common Stock outstanding at the close of business on the date fixed
for such determination plus the number of shares of Common Stock which the
aggregate of the offering price of the total number of shares of Common Stock so
offered for subscription or purchase would purchase at such market price and the
denominator shall be the number of shares of Common Stock outstanding at the
close of business on the date fixed for such determination plus the number of
shares of Common Stock so offered for subscription or purchase, such reduction
to become effective immediately after the opening of business on the day
following the date fixed for such determination. For the purposes of this
paragraph (2), the number of shares of Common Stock at any time outstanding
shall not include shares held in the treasury of the Company but shall include
shares issuable in respect of scrip certificates issued in lieu of fractions of
shares of Common Stock. The Company will not issue any rights or warrants in
respect of shares of Common Stock held in the treasury of the Company.
 
     (3) In case outstanding shares of Common Stock shall be subdivided into a
greater number of shares of Common Stock, the Conversion Price in
 

<PAGE>   92
 
                                       83                                 1504
 
effect at the opening of business on the day following the day upon which such
subdivision becomes effective shall be proportionately reduced, and, conversely,
in case outstanding shares of Common Stock shall each be combined into a smaller
number of shares of Common Stock, the Conversion Price in effect at the opening
of business on the day following the day upon which such combination becomes
effective shall be proportionately increased, such reduction or increase, as the
case may be, to become effective immediately after the opening of business on
the day following the day upon which such subdivision or combination becomes
effective.
 
     (4) In case the Company shall, by dividend or otherwise, distribute to all
holders of its Common Stock evidences of its indebtedness or assets (including
securities, but excluding any rights or warrants referred to in paragraph (2) of
this Section, any dividend or distribution paid in cash out of the retained
earnings of the Company and any dividend or distribution referred to in
paragraph (1) of this Section), the Conversion Price shall be adjusted so that
the same shall equal the price determined by multiplying the Conversion Price in
effect immediately prior to the close of business on the date fixed for the
determination of stockholders entitled to receive such distribution by a
fraction of which the numerator shall be the market price per share (determined
as provided in paragraph (6) of this Section) of the Common Stock on the date
fixed for such determination, reduced by the then fair market value (as
determined by the Board of Directors, whose determination shall be conclusive
and described in a Board Resolution filed with the Trustee) of the portion of
the assets or evidence of indebtedness so distributed applicable to one share of
Common Stock and the denominator shall be such market price per share of the
Common Stock, such adjustment to become effective immediately prior to the
opening of business on the day following the date fixed for the determination of
stockholders entitled to receive such distribution.
 
     (5) The reclassification of Common Stock into securities including other
than Common Stock (other than any reclassification upon a consolidation or
merger to which Section 1511 applies) shall be deemed to involve (a) a
distribution of such securities other than Common Stock to all holders of Common
Stock (and the effective date of such reclassification shall be deemed to be
"the date fixed for the determination of stockholders entitled to receive such
distribution" and "the date fixed for such determination") within the meaning of
paragraph (4) of this Section, and (b) a subdivision or combination, as the case
may be, of the number of shares of Common Stock outstanding immediately prior to
such reclassification into the num-
 
<PAGE>   93
 
1504,1505                              84
 
ber of shares of Common Stock outstanding immediately thereafter (and the
effective date of such reclassification shall be deemed to be "the day upon
which such subdivision becomes effective" or "the day upon which such
combination becomes effective", as the case may be, and "the day upon which such
subdivision or combination becomes effective" within the meaning of paragraph
(3) of this Section).
 
     (6) For the purpose of any computation under paragraphs (2) and (4) of this
Section, the market price on any date shall be deemed to be the average of the
daily market prices for the ten consecutive Business Days selected by the
Company commencing not less than ten nor more than 80 Business Days before the
day in question. The closing price for each day shall be the last reported sales
price regular way on the composite tape or, in case no such reported sale takes
place on such day, the average of the reported closing bid and asked prices
regular way, in either case on the New York Stock Exchange or, if the Common
Stock is not listed or admitted to trading on such Exchange, on the principal
national securities exchange on which the Common Stock is listed or admitted to
trading or, if not listed or admitted to trading on any national securities
exchange, the average of the closing bid and asked prices as furnished by any
New York Stock Exchange member firm selected from time to time by the Company
for that purpose.
 
     (7) The Company may make such reductions in the Conversion Price, in
addition to those required by paragraphs (1), (2), (3) and (4) of this Section,
as it considers to be advisable in order that any event treated for Federal
income tax purposes as a dividend of stock or stock rights shall not be taxable
to the recipients.
 
SECTION 1505.  Notice of Adjustments of Conversion Price.
 
     Whenever the Conversion Price is adjusted as herein provided:
 
          (a) the Company shall compute the adjusted Conversion Price in
     accordance with Section 1504 and shall prepare a certificate signed by the
     Treasurer or an Assistant Treasurer, the Controller or an Assistant
     Controller of the Company setting forth the adjusted Conversion Price and
     showing in reasonable detail the facts upon which such adjustment is based,
     and such certificate shall forthwith be filed with the Trustee and at each
     office or agency maintained for the purpose of conversion of Securities
     pursuant to Section 1002; and
 
          (b) a notice stating that the Conversion Price has been adjusted and
     setting forth the adjusted Conversion Price shall forthwith be

1505,1506                              85
 
     required, and as soon as practicable after it is required, such notice
     shall be prepared by the Company, filed with the Trustee and mailed by the
     Company to all Holders at their last addresses as they shall appear in the
     Security Register.
 
SECTION 1506.  Notice of Certain Corporate Action.
 
     In case:
 
          (a) the Company shall declare a dividend (or any other distribution)
     on Common Stock payable otherwise than in cash out of its retained
     earnings; or
 
          (b) the Company shall authorize the granting to the holders of Common
     Stock of rights or warrants to subscribe for or purchase any shares of
     capital stock of any class or of any other rights; or
 
          (c) of any reclassification of the Common Stock (other than a
     subdivision or combination of its outstanding shares of Common Stock), or
     of any consolidation or merger to which the Company is a party and for
     which approval of any stockholders of the Company is required, or of the
     sale or transfer of all or substantially all of the assets of the Company;
     or
 
          (d) of the voluntary or involuntary dissolution, liquidation or
     winding up of the Company;
 
then the Company shall cause to be filed with the Trustee and at each office or
agency maintained for the purpose of conversion of Securities pursuant to
Section 1002, and shall cause to be mailed to all Holders at their last
addresses as they shall appear in the Security Register, at least 20 days (or
ten days in any case specified in clause (a) or (b) above) prior to the
applicable record or effective date hereinafter specified, a notice stating (x)
the date on which a record is to be taken for the purpose of such dividend,
distribution, rights or warrants, or, if a record is not to be taken, the date
as of which the holders of Common Stock of record to be entitled to such
dividend, distribution, rights or warrants are to be determined, or (y) the date
on which such reclassification, liquidation or winding up is expected to become
effective, and the date as of which it is expected that holders of Common Stock
of record shall be entitled to exchange their shares of Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding up.
The failure to give notice required by this Section or
 
                                                                       
<PAGE>   95
 
1506,1507,1508,1509,1510,1511           86
 
any defect therein shall not affect the legality or validity of any dividend,
distribution, rights, warrants, reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation or winding up, or the vote on any such
action.
 
SECTION 1507.  Company to Reserve Common Stock.
 
     The Company shall at all times reserve and keep available, free from
pre-emptive rights, out of its authorized but unissued Common Stock, for the
purpose of effecting the conversion of Securities, the full number of shares of
Common Stock then issuable upon the conversion of all outstanding Securities.
 
SECTION 1508.  Taxes on Conversions.
 
     The Company will pay any and all transfer taxes that may be payable in
respect of the issue or delivery of shares of Common Stock on conversion of
Securities pursuant thereto. The Company shall not, however, be required to pay
any tax which may be payable in respect of any transfer involved in the issue
and delivery of shares of Common Stock in a name other than that of the Holder
of the Security or Securities to be converted, and no such issue or delivery
shall be made unless and until the Person requesting such issue has paid to the
Company the amount of any such tax, or has established to the satisfaction of
the Company that such tax has been paid.
 
SECTION 1509.  Covenant as to Common Stock.
 
     The Company covenants that all shares of Common Stock which may be issued
upon conversion of Securities will upon issue be fully paid and nonassessable.
 
SECTION 1510.  Cancellation of Converted Securities.
 
     All Securities delivered for conversion shall be delivered to the Trustee
for cancellation and the Trustee shall dispose of the same as provided in
Section 309.
 
SECTION 1511.  Provisions in Case of Consolidation, Merger or Sale of
  Assets.
 
     In case of any consolidation of the Company with, or merger of the Company
into, any other corporation, any merger of another corporation into the Company
(other than a merger which does not result in any
 

<PAGE>   96
 
                                       87                                 1511
 
reclassification, conversion, exchange or cancellation of outstanding shares of
Common Stock of the Company) or any sale or transfer of all or substantially all
of the assets of the Company, the corporation formed by such consolidation or
resulting from such merger or which acquires such assets, as the case may be,
shall execute and deliver to the Trustee a supplemental indenture providing that
the Holder of each Security then outstanding shall have the right thereafter,
during the period such Security shall be convertible as specified in Section
1501, to convert such Security only into the kind and amount of securities, cash
and other property receivable upon such consolidation, merger, sale or transfer
by a holder of the number of shares of Common Stock of the Company into which
such Security might have been converted immediately prior to such consolidation,
merger, sale or transfer, assuming such holder of Common Stock of the Company
(i) is not a corporation with which the Company consolidated or into which the
Company merged or which merged into the Company or to which such sale or
transfer was made, as the case may be ("constituent corporation"), or an
Affiliate of a constituent corporation and (ii) failed to exercise his rights of
election, if any, as to the kind or amount of securities, cash and other
property receivable upon such consolidation, merger, sale or transfer (provided
that if the kind or amount of securities, cash and other property receivable
upon such consolidation, merger, sale or transfer is not the same for each share
of Common Stock of the Company held immediately prior to such consolidation,
merger, sale or transfer by others than a constituent corporation or an
Affiliate thereof and in respect of which such rights of election shall not have
been exercised ("non-electing share"), then for the purpose of this Section the
kind and amount of securities, cash and other property receivable upon such
consolidation, merger, sale or transfer by each non-electing share shall be
deemed to be the kind and amount so receivable per share by a plurality of the
non- electing shares). Such supplemental indenture shall provide for adjustments
which, for events subsequent to the effective date of such supplemental
indenture, shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article. The above provisions of this Section
shall similarly apply to successive consolidations, mergers, sales or transfers.
 
     This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counter-parts
shall together constitute but one and the same instrument.

Anadarko Petroleum Corporation
17001 Northchase Drive
Houston, Texas  77060

Dear Sirs:

         We have acted as special counsel to Anadarko Petroleum Corporation (the
"Company") in connection with the Company's Registration Statement on Form S-3
being filed with the Securities and Exchange Commission under the Securities Act
of 1933, as amended, with respect to the contemplated issuance by the Company
from time to time of up to $300,000,000 aggregate initial offering price of Debt
Securities, Preferred Stock and/or Common Stock (collectively, the
"Securities"). The Debt Securities are to be issued pursuant to a Senior
Indenture between the Company and Harris Trust and Savings Bank, as trustee, the
form of which has been filed as an Exhibit to the Registration Statement (the
"Senior Indenture") or a Subordinated Indenture between the Company and First
Chicago NBD, as trustee, the form of which has been filed as an Exhibit to the 
Registration Statement (the "Subordinated Indenture").

         We have examined originals or copies, certified or otherwise identified

         On the basis of the foregoing, we are of the opinion that:

                       (1) when the Senior Indenture or the Subordinated
                  Indenture has been duly authorized, executed and delivered and
                  when the specific terms of a particular Debt Security have
                  been duly authorized and established in accordance with the
                  Senior Indenture or the Subordinated Indenture, as the case
                  may be, and such Debt Security has been duly authorized and
                  executed, authenticated, issued and delivered in accordance
                  with the Senior Indenture or the Subordinated Indenture, as
                  the case may be, against payment therefor in accordance with
                  the applicable underwriting or other agreement, such Debt
                  Security will constitute the valid and binding obligation of
                  the Company; and

                           (2) the shares of Common Stock, par value $0.10 per
                  share, of the Company (the "Common Stock"), and the shares of
                  Preferred Stock, par value $1.00 per share, of the Company
                  (the "Preferred Stock"), when such shares of Common Stock or
                  Preferred Stock, as the case may be, have been duly
                  authorized, issued and delivered against payment therefor in
                  accordance with the applicable underwriting or other
                  agreement, will be validly issued, fully paid and
                  non-assessable.

         In connection with our opinions expressed above, we have assumed that,
at or prior to the time of the delivery of any such Security, the Registration
Statement has been declared effective, that the authorization of the Securities
will be applicable to such Security, will not have been modified or rescinded
and there will not have occurred any change in law affecting the validity or
enforceability of such Security. We have also assumed that none of the terms of
any Security to be established subsequent to the date hereof nor the issuance
and delivery of such Security, nor the compliance by the Company with the terms
of such Security, will violate any applicable law or will result in a violation
of any provision of any instrument or agreement then binding upon the Company,
or any restriction imposed by any court or governmental body having jurisdiction
over the Company.

The ratios of earnings to fixed charges were computed by dividing earnings by
fixed charges.  For this purpose, earnings include income before income taxes
and fixed charges.  Fixed charges include interest and amortization of debt
expenses, and the estimated interest component of rentals.  Certain amounts for
prior years have been restated to conform to the current presentation.

During the three months ended March 31, 1997 and five years ended December 31,
1996, there were no shares of preferred stock outstanding.  Accordingly, the
ratio of earnings to combined fixed charges and preferred stock dividends for
the three months and each of the five years is the same as the ratio of
earnings to fixed charges.
