FORM, EXCHANGE, REGISTRATION AND TRANSFER
 
  The Securities of a series may be issued solely as Registered Securities,
solely as Bearer Securities (with or without coupons attached) or as both
Registered Securities and Bearer Securities. Securities of a series may be
issuable in whole or part in the form of one or more global Securities, as
described below under "Global Securities."
 
  Registered Securities of any series will be exchangeable for other
Registered Securities of the same series of any authorized denominations and
of a like aggregate principal amount and tenor. In addition, if Securities of
any series are issuable as both Registered Securities and as Bearer
Securities, at the option of the Holder, subject to the terms of the
Indenture, Bearer Securities (accompanied by all unmatured coupons, except as
provided below, and all matured coupons in default) of such series will be
exchangeable for Registered Securities of the same series of any authorized
denominations and of a like aggregate principal amount and tenor. Unless
otherwise indicated in an applicable Prospectus Supplement, any Bearer
Security surrendered in exchange for a Registered Security between a Regular
Record Date or a Special Record Date and the relevant date for payment of
interest will be surrendered without the coupon relating to such date for
payment of interest and such interest will not be payable in respect of the
Registered Security issued in exchange for such Bearer Security, but will be
payable only to the Holder of such coupon when due in accordance with the
terms of the Indenture. Bearer Securities will not be issued in exchange for
Registered Securities.
 
  Securities may be presented for exchange as provided above, and, unless
otherwise indicated in an applicable Prospectus Supplement, Registered
Securities may be presented for registration of transfer (duly endorsed or
accompanied by a duly executed written instrument of transfer), at the office
of the Security Registrar
 
                                       5
<PAGE>
 
or at the office of any transfer agent designated by Occidental for such
purpose with respect to any series of Securities and referred to in an
applicable Prospectus Supplement, without service charge and upon payment of
any taxes and other governmental charges as described in the Indenture. Such
exchange or transfer, as the case may be, will be effected upon the Security
Registrar or such transfer agent, as the case may be, being satisfied with the
documents of title and identity of the person making the request. Occidental
has initially appointed the Trustee as Security Registrar. If a Prospectus
Supplement refers to any transfer agent (in addition to the Security
Registrar) designated by Occidental with respect to any series of Securities,
Occidental may at any time rescind the designation of any such transfer agent
or approve a change in the location through which any such transfer agent
acts, except that, if Securities of a series are issuable only as Registered
Securities, Occidental will be required to maintain a transfer agent in each
Place of Payment for such series, and, if Securities of a series are issuable
as Bearer Securities, Occidental will be required to maintain a transfer agent
in New York City and in a Place of Payment for such series located outside the
United States. Occidental may at any time designate additional transfer agents
with respect to any series of Securities.
 
  Occidental will not be required to (i) issue, register the transfer of or
exchange Securities of any series during a period beginning at the opening of
business 15 days before any selection of Securities of that series to be
redeemed and ending (subject to certain exceptions) at the close of business
on (a) if Securities of the series are issuable only as Registered Securities,
the day of mailing of the relevant notice of redemption and (b) if Securities
of the series are issuable as Bearer Securities, the day of the first
publication of the relevant notice of redemption or, if Securities of the
series are also issuable as Registered Securities and there is no publication,
the mailing of the relevant notice of redemption; (ii) register the transfer
of or exchange any Registered Security, or portion thereof, called for
redemption, except the unredeemed portion of any Registered Security being
redeemed in part; or (iii) exchange any Bearer Security called for redemption,
except to exchange such Bearer Security for a Registered Security of that
series and of like tenor and principal amount that is immediately surrendered
for redemption.
 
PAYMENT AND PAYING AGENTS
 
  Unless otherwise indicated in an applicable Prospectus Supplement, payment
of principal of and interest, if any, on Registered Securities will be made at
the office of such Paying Agent or Paying Agents as Occidental may designate
from time to time, except that, at the option of Occidental, payment of any
interest may be made (i) by check mailed to the address of the Person entitled
thereto, as such address shall appear in the Security Register, or (ii) by
wire transfer to an account maintained by the Person entitled thereto, as
specified in the Security Register. Unless otherwise indicated in an
applicable Prospectus Supplement, payment of any installment of interest on a
Registered Security will be made to the Person in whose name such Registered
Security is registered at the close of business on the Regular Record Date for
such interest installment.
 
  Unless otherwise indicated in an applicable Prospectus Supplement, interest
shall be computed on the basis of a 360-day year comprised of twelve 30-day
months.
 
  Unless otherwise indicated in an applicable Prospectus Supplement, payment
of principal of and interest, if any, on Bearer Securities will be made,
subject to any applicable laws and regulations, at the offices of such Paying
Agent or Paying Agents outside the United States as Occidental may designate
from time to time, or by check mailed to an address or by transfer to an
account maintained by the payee outside the United States. Unless otherwise
indicated in an applicable Prospectus Supplement, any payment of an
installment of interest on any Bearer Security will be made only against
surrender of the coupon relating to such interest installment.
 
  Unless otherwise indicated in an applicable Prospectus Supplement, the
Trustee, acting through its Corporate Trust Office, will be designated as
Occidental's sole Paying Agent for payments with respect to Securities that
are issuable solely as Registered Securities and as Occidental's Paying Agent
in the Borough of Manhattan, The City of New York, for payments with respect
to Securities (subject to any limitations described in any applicable
Prospectus Supplement) that are issuable as Bearer Securities. Any Paying
Agent outside the United States and any other Paying Agent in the United
States initially designated by Occidental for the Offered
 
                                       6
<PAGE>
 
Securities will be named in an applicable Prospectus Supplement. Occidental
may at any time designate one or more additional Paying Agents or rescind the
designation of any Paying Agent or approve a change in the office through
which any Paying Agent acts, except that, if Securities of a series are
issuable only as Registered Securities, Occidental will be required to
maintain a Paying Agent in each Place of Payment for such series, and, if
Securities of a series are issuable as Bearer Securities, Occidental will be
required to maintain (i) a Paying Agent in the Borough of Manhattan, The City
of New York, for payments with respect to any Registered Securities of the
series (and for payments with respect to Bearer Securities of the series in
the circumstances described in the Indenture, but not otherwise) and (ii) a
Paying Agent in a Place of Payment located outside the United States where
Securities of such series and any related coupons may be presented and
surrendered for payment; provided, however, that if the Securities of such
series are listed on The London Stock Exchange or the Luxembourg Stock
Exchange or any other stock exchange located outside the United States and
such stock exchange shall so require, Occidental will maintain a Paying Agent
in London, Luxembourg or any other required city located outside the United
States, as the case may be, for the Securities of such series.
 
  All moneys paid by Occidental to a Paying Agent for the payment of principal
of or interest, if any, on any Security that remain unclaimed at the end of
two years after such principal or interest shall have become due and payable
will be repaid to Occidental, and the Holder of such Security or any coupon
will thereafter look only to Occidental for payment thereof.
 
GLOBAL SECURITIES
 
  The Securities of a series may be issued in whole or in part in global form.
A Security in global form will be deposited with, or on behalf of, a
Depositary, which will be identified in an applicable Prospectus Supplement. A
global Security may be issued in either registered or bearer form and in
either temporary or definitive form. A Security in global form may not be
transferred, except as a whole by the Depositary for such Security to a
nominee of such Depositary, or by a nominee of such Depositary to such
Depositary or another nominee of such Depositary, or by such Depositary or any
such nominee to a successor of such Depositary or a nominee of such successor.
If any Securities of a series are issuable in global form, the applicable
Prospectus Supplement will describe the circumstances, if any, under which
beneficial owners of interests in any such global Security may exchange such
interests for definitive Securities of such series and of like tenor and
principal amount in any authorized form and denomination, the manner of
payment of principal of and interest, if any, on any such global Security and
the specific terms of the depositary arrangement with respect to any such
global Security.
 
CERTAIN COVENANTS OF OCCIDENTAL
 
  Limitation on Liens. Occidental will not, nor will it permit any
Consolidated Subsidiary (as defined below) to, incur, create, assume,
guarantee or otherwise become liable with respect to any Secured Debt (as
defined below), unless the Securities are secured equally and ratably with (or
prior to) such Secured Debt. This covenant will not apply to: (i) Liens (as
defined below) existing on the date of the Indenture; (ii) Liens existing on
property of, or on any shares of stock or Indebtedness of, any corporation at
the time such corporation becomes a Consolidated Subsidiary; (iii) Liens in
favor of Occidental or a Consolidated Subsidiary; (iv) Liens in favor of
governmental bodies to secure progress, advance or other payments; (v) Liens
existing on property, shares of stock or Indebtedness at the time of
acquisition thereof (including acquisition through merger or consolidation) or
Liens to secure the payment of all or any part of the purchase price thereof
or the cost of construction, installation, renovation, improvement or
development thereon or thereof or to secure any Indebtedness incurred prior
to, at the time of, or within 360 days after the later of the acquisition,
completion of such construction, installation, renovation, improvement or
development or the commencement of full operation of such property or within
360 days after the acquisition of such shares or Indebtedness for the purpose
of financing all or any part of the purchase price or cost thereof; and (vi)
any extension, renewal or refunding of any Liens referred to in the foregoing
clauses (i) through (v). Notwithstanding the foregoing, Occidental and one or
more Consolidated Subsidiaries may incur, create, assume, guarantee or
otherwise become liable with respect to Secured Debt that would otherwise be
subject to the foregoing restrictions if, after giving effect thereto, the
aggregate amount of
 
                                       7
<PAGE>
 
all Secured Debt, together with all Discounted Rental Value (as defined below)
in respect of sale and leaseback transactions subject to the restrictions
discussed in the following paragraph (excluding sale and leaseback
transactions exempted from such restrictions pursuant to clause (i) or (ii) of
the last sentence of such paragraph), would not exceed 10% of consolidated Net
Tangible Assets (as defined below) of Occidental and its consolidated
subsidiaries.
 
  Limitation on Sale and Leaseback Transactions. Occidental will not nor will
it permit any Consolidated Subsidiary to sell and lease back any Principal
Domestic Property (as defined below) unless: (i) the transaction is one in
which the sale has occurred within 360 days after the later of the
acquisition, completion of construction or commencement of full operations of
the Principal Domestic Property; (ii) Occidental or such Consolidated
Subsidiary could subject such Principal Domestic Property to a Lien pursuant
to the provisions described above under "Limitation on Liens" in an amount
equal to the Discounted Rental Value with respect to the sale and leaseback
transaction without equally and ratably securing the Securities; or (iii)
Occidental or such Consolidated Subsidiary, within 120 days after such sale,
applies or causes to be applied to the retirement of its Funded Debt (as
defined below) an amount (subject to credits for certain voluntary retirements
of Funded Debt) not less than the greater of (a) the net proceeds of the sale
of the Principal Domestic Property leased pursuant to such arrangement or (b)
the fair value (as determined in any manner approved by the Board of Directors
of Occidental) of the Principal Domestic Property so leased. This restriction
will not apply to any sale and leaseback transaction (i) between Occidental
and a Consolidated Subsidiary or between Consolidated Subsidiaries or (ii)
involving the taking back of a lease for a period, including renewals, of not
more than three years.
 
  Other than the limitations in the Indenture on Liens and sale and leaseback
transactions described above, the provisions of the Indenture do not afford
Holders of the Debt Securities protection in the event of a highly leveraged
transaction, reorganization, restructuring, change in control, merger or
similar transaction involving Occidental that may adversely affect Holders of
the Debt Securities.
 
CERTAIN DEFINITIONS
 
  "Consolidated Subsidiary" means any Subsidiary included in the financial
statements of Occidental and its Subsidiaries prepared on a consolidated basis
in accordance with generally accepted accounting principles.
 
  "Discounted Rental Value" means, as to any particular lease under which any
Person is at the time liable and at any date as of which the amount thereof is
to be determined, the total net amount of rent (after deducting the amount of
rent to be received by such Person under noncancelable subleases) required to
be paid by such Person under such lease during the remaining noncancelable
term thereof (including any such period for which such lease has been extended
or may, at the option of the lessor, be extended), discounted from the
respective due dates thereof to such date at a rate per annum of 11 3/4%. The
net amount of rent required to be paid under any such lease for any such
period shall be the aggregate amount of the rent payable by the lessee with
respect to such period, after excluding amounts required to be paid on account
of maintenance and repairs, insurance, taxes, water rates and similar charges.
In the case of any lease which is terminable by the lessee upon the payment of
a penalty, such net amount shall also include the amount of such penalty, but
no rent shall be considered as required to be paid under such lease subsequent
to the first date upon which it may be so terminated. If and to the extent the
amount of any rent during any future period is not definitely determinable
under the lease in question, the amount of such rent shall be estimated in
such reasonable manner as the Board of Directors of Occidental may in good
faith determine.
 
  "Funded Debt" means all Indebtedness maturing one year or more from the date
of the creation thereof, all Indebtedness directly or indirectly renewable or
extendible, at the option of the debtor, by its terms or by the terms of any
instrument or agreement relating thereto, to a date one year or more from the
date of the creation thereof, and all Indebtedness under a revolving credit or
similar agreement obligating the lender or lenders to extend credit over a
period of one year or more, even though such Indebtedness may also conform to
the definition of Short-Term Borrowing.
 
                                       8
<PAGE>
 
  "Lien" means and includes any mortgage, pledge, lien, security interest,
conditional sale or other title retention agreement or other similar
encumbrance to secure Indebtedness for borrowed money but excluding any
security interest which a lessor may be deemed to have under a lease and any
lien which may be deemed to exist under a Production Payment or under any
subordination arrangement. "Production Payment" means any economic interest in
oil, gas or mineral reserves which (i) entitles the holder thereof to a
specified share of future production from such reserves, free of the costs and
expenses of such production and (ii) terminates when a specified quantity of
such share of future production from such reserves has been delivered or a
specified sum has been realized from the sale of such share of future
production from such reserves.
 
  "Net Tangible Assets" of any specified Person means the total of all assets
properly appearing on a balance sheet of such Person prepared in accordance
with generally accepted accounting principles, after deducting from such
total, without duplication of deductions, (i) all Current Liabilities of such
Person; (ii) that portion of the book amount of all such assets which would be
treated as intangibles under generally accepted accounting principles,
including, without limitation, all such items as goodwill, trademarks, trade
names, brands, copyrights, patents, licenses and rights with respect to the
foregoing and unamortized debt discount and expense; and (iii) the amount, if
any, at which any stock of such Person appears on the asset side of such
balance sheet.
 
  "Principal Domestic Property" means any (i) developed oil or gas producing
property or (ii) processing or manufacturing plant, in each case which as of
the date of the Indenture is or thereafter is owned or leased by Occidental or
any Consolidated Subsidiary and which is located in the continental United
States (provided, however, that any such property or plant declared by the
Board of Directors by Board Resolution not to be of material importance to the
business of Occidental and its Consolidated Subsidiaries taken as a whole will
be excluded from the foregoing definition).
 
  "Secured Debt" means any Indebtedness of Occidental or any Consolidated
Subsidiary, secured by a Lien on any Principal Domestic Property or on any
shares of stock or on any Indebtedness of any Consolidated Subsidiary which
owns any Principal Domestic Property.
 
MERGER AND CONSOLIDATION
 
  Occidental may consolidate with or merge into any other corporation, and
Occidental may convey, transfer or lease its properties and assets
substantially as an entirety to any Person, provided that: (i) the corporation
formed by such consolidation or into which Occidental is merged, or the Person
that acquires by conveyance or transfer or which leases the properties and
assets of Occidental substantially as an entirety, shall be organized and
existing under the laws of the United States, any State thereof or the
District of Columbia and shall expressly assume the payment of the principal
of and interest on the Securities and the performance of every covenant of the
Indenture and the Securities on the part of Occidental to be performed or
observed; and (ii) immediately after giving effect to such transaction, no
Event of Default (as described below), and no event which, after notice or
lapse of time, or both, would become an Event of Default, shall have happened
and be continuing.
 
EVENTS OF DEFAULT
 
  The following are Events of Default under the Indenture with respect to each
series of Securities individually: (i) default in the payment of any
installment of interest on any Security of such series when due, continued for
30 days; or (ii) default in the payment of the principal of any Security of
such series when due; or (iii) default in the performance, or breach, of any
other covenant or warranty of Occidental in the Indenture (other than a
covenant or warranty that is solely for the benefit of other series of the
Securities), continued for 60 days after written notice by the Trustee or the
Holders of at least 25% in principal amount of the Outstanding Securities of
such series; or (iv) acceleration of any indebtedness for money borrowed by
Occidental under the terms of the instrument under which such indebtedness is
or may be outstanding, if such indebtedness is not discharged or such
acceleration is not annulled or rescinded within 20 days after written notice
by the Trustee or the Holders of at least 25% in principal amount of the
Outstanding Securities of such series (provided, that no Event of Default
under this clause (iv) shall be deemed to exist as a result of an acceleration
of any such
 
                                       9
<PAGE>
 
indebtedness if the principal of and interest on such indebtedness, when added
to the principal of and interest on all other such indebtedness which has been
accelerated as aforesaid (excluding any such indebtedness which has been
discharged or as to which the acceleration has been duly rescinded or
annulled), shall not exceed $50,000,000); or (v) certain events of bankruptcy,
insolvency or reorganization of Occidental; or (vi) any other event designated
in the relevant Prospectus Supplement as an "Event of Default" with respect to
the Securities of such series. If an Event of Default with respect to the
Securities of any series occurs and is continuing, the Trustee or Holders of
not less than 25% in principal amount of the Outstanding Securities of such
series may declare the principal amount (or, if any of the Securities of such
series are Discount Securities, such portion of the principal amount of such
Securities as may be specified by the terms thereof) of all of the Securities
of such series to be due and payable immediately. Under certain circumstances,
the Holders of a majority in principal amount of the Outstanding Securities of
such series may rescind such a declaration.
 
  The Holders of a majority in principal amount of the Outstanding Securities
of any series may 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, among other things, such direction is not in conflict with any
rule of law or the Indenture. In case an Event of Default occurs (and is not
cured), the Trustee is required to exercise such of its rights and powers
under the Indenture, and use the same degree of care and skill in their
exercise, as a prudent person would exercise or use under the circumstances in
the conduct of his own affairs. Subject to such provisions, the Trustee is
under no obligation to exercise any of its rights or powers under the
Indenture at the request or direction of any of the Holders of the Securities
of any series, unless such Holders have offered to the Trustee reasonable
security or indemnity against the costs, expenses and liabilities that might
be incurred by it in compliance with any such request or direction.
 
MODIFICATION AND WAIVER
 
  Occidental and the Trustee may execute a supplemental indenture, without the
consent of the Holders of the Securities or any related coupons: (i) to add to
the covenants, agreements and obligations of Occidental for the benefit of the
Holders of all the Securities of any series or to surrender any right or power
conferred in the Indenture upon Occidental; (ii) to evidence the succession of
another person to Occidental and the assumption by it of the covenants of
Occidental in the Indenture and the Securities; (iii) to provide that Bearer
Securities may be registrable as to principal, to change or eliminate any
restrictions on the payment of principal of or interest, if any, on Bearer
Securities, to permit Bearer Securities to be issued in exchange for
Registered Securities, to permit Bearer Securities to be issued in exchange
for Bearer Securities of other authorized denominations or to permit the
issuance of Securities in uncertificated form, provided that any such action
shall not adversely affect the interests of the Holders of Securities of any
series or any related coupons in any material respect; (iv) to establish the
form or terms of Securities of any series and any related coupons as permitted
by Sections 201 and 301 of the Indenture; (v) to provide for the acceptance of
appointment under the Indenture of a successor Trustee with respect to the
Securities of one or more series and to add to or change any provisions of the
Indenture as shall be necessary to provide for or facilitate the
administration of the trusts by more than one Trustee; (vi) to cure any
ambiguity or correct any inconsistency in the Indenture or make other changes,
provided that no such action shall adversely affect the interests of the
Holders of the Securities; (vii) to add to, change or eliminate any provisions
(which addition, change or elimination may apply to one or more series of
Securities), provided that any such addition, change or elimination neither
(a) applies to any Security of any series created prior to the execution of
such supplemental indenture that is entitled to the benefit of such provision
nor (b) modifies the rights of the Holder of any such Security with respect to
such provision; or (viii) to secure the Securities.
 
  With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of the series affected by such
supplemental indenture, Occidental and the Trustee also may execute a
supplemental indenture to add provisions to, or change in any manner or
eliminate any provisions of, the Indenture with respect to such series of
Securities or modify in any manner the rights of the holders of the Securities
of such series and any related coupons under the Indenture, provided that no
such supplemental indenture will, without the consent of the Holder of each
Outstanding Security affected thereby: (i) change the
 
                                      10
<PAGE>
 
stated maturity of the principal of, or any installment of principal or
interest on, any such Security, or reduce the amount of principal of any such
Discount Security that would be due and payable upon declaration of
acceleration of maturity thereof; (ii) reduce the principal amount of, or the
rate of interest on, or any premium payable on, any such Security; (iii)
change the place or currency of payment of principal or interest, if any, on
any such Security; (iv) impair the right to institute suit for the enforcement
of any payment on or with respect to any such Security; (v) reduce the above-
stated percentage of Holders of Securities of any series necessary to modify
or amend the Indenture; or (vi) modify the foregoing requirements or reduce
the percentage in principal amount of Outstanding Securities of any series
necessary to waive any covenant or past default. Holders of not less than a
majority in principal amount of the Outstanding Securities of any series may
waive certain past defaults and may waive compliance by Occidental with
certain of the restrictive covenants in the Indenture (including the
restrictive covenants described above under "Certain Covenants of Occidental")
with respect to the Securities of such series.
 
DISCHARGE
 
  Unless otherwise indicated in an applicable Prospectus Supplement,
Occidental may terminate at any time its obligations under the Indenture with
respect to the Securities of any series by (i)(a) delivering all Outstanding
Securities of such series to the Trustee for cancellation or (b) depositing
with the Trustee funds or non-callable United States government obligations
sufficient to pay all remaining principal and interest on the Securities of
such series and (ii) complying with certain other provisions of the Indenture.
 
  If Occidental exercises its right to satisfy and discharge its obligations
under the Indenture with respect to any series of the Debt Securities prior to
its maturity by depositing funds or non-callable United States government
obligations in trust for holders of outstanding Debt Securities of that
series, such satisfaction and discharge ("discharge"), under present law, is
likely to be treated as a redemption of the Debt Securities of that series
prior to maturity in exchange for the property deposited in trust. In such
event, each holder would generally recognize, at the time of discharge, gain
or loss measured by the difference between (i) the sum of (a) the amount of
any cash and (b) the fair market value of any property deposited in trust
deemed received by the holder (except to the extent attributable to accrued
interest) and (ii) the holder's tax basis in the Debt Securities deemed
surrendered. Thereafter, each holder would be treated as if it held an
undivided interest in the cash (or investments made therewith) and the
property held in trust. Each holder would generally be subject to tax
liability in respect of interest income and original issue discount, if
applicable, thereon and would recognize any gain or loss upon any disposition,
including redemption, of the assets held in trust. Although tax might be owed,
the holder of a discharged Debt Security would not receive cash (except for
current payments of interest on such Debt Security) until the maturity or
earlier redemption of such Debt Security. Such tax treatment could affect the
purchase price that a holder would receive upon the sale of the Debt
Securities.
 
REPORTS
 
  Occidental is required to furnish to the Trustee annually (i) a statement as
to the fulfillment by Occidental of all of its covenants under the Indenture
and (ii) within 20 days after the occurrence thereof, notice of each
acceleration which, with the giving of notice and the lapse of time, would be
an Event of Default, as described above in clause (iv) under "Events of
Default."
 
THE TRUSTEE
 
  The Trustee is a New York banking corporation. The Trustee is a
participating lender under a revolving credit agreement of Occidental and
provides commercial banking services to Occidental and certain of its
subsidiaries. The Indenture contains certain limitations on the rights of the
Trustee, as a creditor of Occidental, to obtain payment of claims in certain
cases or to realize on certain property received in respect of any such claim
as security or otherwise. The Trustee will be permitted to engage in other
transactions with Occidental and its subsidiaries; provided, however, that if
the Trustee acquires any conflicting interest at such time as a default is
pending under the Indenture, it must (with certain exceptions) eliminate such
conflict or resign.

                             PLAN OF DISTRIBUTION
 
  Occidental may sell Debt Securities to one or more underwriters for public
offering and sale by them or may sell Debt Securities to investors directly or
through agents or dealers. Any such underwriter, agent or dealer involved in
the offer and sale of the Debt Securities will be named in the applicable
Prospectus Supplement. Occidental may also sell Offered Securities to an agent
as principal.
 
  Underwriters may offer and sell the Offered Securities at a fixed price or
prices, which may be changed, or from time to time at market prices prevailing
at the time of sale, at prices related to such prevailing market prices or at
negotiated prices. Occidental also may, from time to time, authorize
underwriters acting as its agents to offer and sell the Offered Securities
upon the terms and conditions set forth in any Prospectus Supplement. In
connection with the sale of Offered Securities, underwriters may be deemed to
have received compensation from Occidental in the form of underwriting
discounts or commissions and may also receive commissions from purchasers of
Offered Securities for whom they may act as agent. Underwriters may sell
Offered Securities to or through dealers, and such dealers may receive
compensation in the form of discounts, concessions or commissions from the
underwriters and/or commissions (which may be changed from time to time) from
the purchasers for whom they may act as agent.
 
  If a dealer is utilized in the sale of the Offered Securities in respect of
which this Prospectus is delivered, Occidental will sell such Offered
Securities to such dealer, as principal. The dealer may then resell such
Offered Securities to the public at varying prices to be determined by such
dealer at the time of resale.
 
  Any underwriting compensation paid by Occidental to underwriters or agents
in connection with the offering of Offered Securities, and any discounts,
concessions or commissions allowed by underwriters to participating dealers,
will be set forth in an applicable Prospectus Supplement. Underwriters,
dealers and agents participating in the distribution of the Offered Securities
may be deemed to be underwriters under the Securities Act, and any discounts
and commissions received by them and any profit realized by them on resale of
the Offered Securities may be deemed to be underwriting discounts and
commissions under the Securities Act. Underwriters, dealers and agents may be
entitled under agreements with Occidental to indemnification against and
contribution toward certain civil liabilities, including liabilities under the
Securities Act, and to reimbursement by Occidental for certain expenses.
 
  If so indicated in an applicable Prospectus Supplement, Occidental will
authorize dealers acting as its agents to solicit offers by certain
institutions to purchase Offered Securities from Occidental at the public
offering price set forth in such Prospectus Supplement pursuant to Delayed
Delivery Contracts ("Contracts") providing for payment and delivery on the
date or dates stated in such Prospectus Supplement. Each Contract will be for
an amount not less than, and the aggregate principal amount or offering price
of Offered Securities sold pursuant to Contracts shall not be less nor more
than, the respective amounts stated in such Prospectus Supplement.
Institutions with whom Contracts, when authorized, may be made include
commercial and savings banks, insurance companies, pension funds, investment
companies, educational and charitable institutions and other institutions, but
will in all cases be subject to the approval of Occidental.
 
  Offered Securities may also be offered and sold, if so indicated in the
Prospectus Supplement, in connection with a remarketing upon their purchase,
in accordance with a redemption or repayment pursuant to their terms, or
otherwise, by one or more firms ("remarketing firms"), acting as principals
for their own accounts or as agents for Occidental. Any remarketing firm will
be identified and the terms of its agreement, if any, with Occidental and its
compensation will be described in the Prospectus Supplement. Remarketing firms
may be deemed to be underwriters in connection with the Offered Securities
remarketed thereby. Remarketing firms may be entitled under agreements which
may be entered into with Occidental to indemnification by Occidental against
certain liabilities, including liabilities under the Securities Act.
 
  The Debt Securities may or may not be listed on a national securities
exchange or a foreign securities exchange. No assurances can be given that
there will be a market for any of the Debt Securities.

                                 LEGAL MATTERS
 
  Certain legal matters with respect to the legality of the Debt Securities
being offered hereby will be passed upon for Occidental by Robert E. Sawyer,
Esq., Associate General Counsel of Occidental. Mr. Sawyer beneficially owns,
and has rights to acquire under employee stock options, an aggregate of less
than 1% of the outstanding common stock of Occidental.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Section 145 of the Delaware General Corporation Law authorizes a court to
award, or a corporation's board of directors to grant, indemnity to directors
and officers under certain circumstances for liabilities incurred in
connection with their activities in such capacities (including reimbursement
for expenses incurred). Occidental's Restated Certificate of Incorporation, as
amended, provides for the elimination of personal liability of its directors
to the full extent permitted by the Delaware General Corporation Law and
Occidental has entered into indemnification agreements with each director and
certain officers providing for additional indemnification. Article VIII of
Occidental's By-laws provides that Occidental shall indemnify directors and
officers under certain circumstances for liabilities and expenses incurred by
reason of their activities in such capacities. In addition, Occidental has
insurance policies that provide liability coverage to directors and officers
while acting in such capacities.
 
  The forms of Underwriting Agreement and Distribution Agreement filed as
Exhibits 1.1 and 1.2, respectively, to this Registration Statement provide for
indemnification of directors and officers of Occidental by the underwriters or
agents, as the case may be, against certain liabilities.

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 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.
 
    (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 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in 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 the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
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 by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act
and will be governed by the final adjudication of such issue.

                        OCCIDENTAL PETROLEUM CORPORATION

                         FORM OF UNDERWRITING AGREEMENT



                                                                          [Date]



Dear Sirs:

     Occidental Petroleum Corporation, a Delaware corporation (the "Company"),
confirms its agreement with [insert names of lead underwriters] (collectively
the "Underwriters," which term shall also include any underwriter substituted as
hereinafter provided in Section 11 hereof) with respect to the sale by the
Company and the purchase by the Underwriters, acting severally and not jointly,
of the respective principal amounts set forth opposite their names on Schedule A
hereto, of the Company's                          (the "Notes").  The Notes are
to be issued pursuant to the Indenture (the "Indenture", which term, for the
purpose of this Agreement, shall include the Officers' Certificate with respect
to the Notes delivered pursuant to Sections 201 and 301 of the Indenture), dated
as of April 1, 1998, between the Company and The Bank of New York, as trustee
(the "Trustee").

     The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 333-     ) and, if
applicable, one or more amendments thereto for the registration of senior debt
securities, including the Notes, under the Securities Act of 1933, as amended
(the "1933 Act"), and the offering thereof from time to time in accordance with
Rule 415 of the rules and regulations of the Commission under the 1933 Act (the
"1933 Act Regulations"). Such registration statement (as amended, if applicable)
has been declared effective 
<PAGE>
 
by the Commission and the Indenture has been qualified under the Trust Indenture
Act of 1939, as amended (the "1939 Act"). Such registration statement (as
amended, if applicable) and the prospectus constituting a part thereof, together
with any prospectus supplement relating to the Notes, including, in each case,
all Incorporated Documents (as hereinafter defined), are referred to herein as
the "Registration Statement" and the "Prospectus," respectively, except that, if
any revised prospectus or revised prospectus supplement shall be provided to the
Underwriters by the Company for use in connection with the offering of the Notes
that is not required to be filed by the Company pursuant to Rule 424(b) of the
1933 Act Regulations, the term "Prospectus" shall refer to such revised
prospectus or prospectus supplement, as the case may be, from and after the time
it is first provided to the Underwriters for such use. The term "Registration
Statement" shall include any related registration statement filed pursuant to
Rule 462(b) of the 1933 Act Regulations. Any reference herein to the
Registration Statement, any preliminary prospectus or the Prospectus shall be
deemed to refer to and include the documents, financial statements and schedules
incorporated or deemed to be incorporated by reference therein pursuant to Item
12 of Form S-3 under the 1933 Act, and any reference to any amendment or
supplement to the Registration Statement or the Prospectus shall be deemed to
refer to and include any documents, financial statements and schedules filed by
the Company with the Commission under the Securities Exchange Act of 1934, as
amended (the "1934 Act"), and so incorporated or deemed to be incorporated by
reference (such incorporated documents, financial statements and schedules being
herein called the "Incorporated Documents"). Notwithstanding the foregoing, for
purposes of this Agreement any prospectus supplement prepared or filed with
respect to an offering pursuant to the Registration Statement of a series of
debt securities other than the Notes shall not be deemed to have supplemented
the Prospectus.

     The Company understands that the Underwriters propose to make a public
offering of the Notes as soon as the Underwriters deem advisable after this
Agreement has been executed and delivered.

Section 1.  Representations and Warranties.

     (a)  The Company represents and warrants to each of the Underwriters as
follows:

          (i)  The Incorporated Documents, when they were filed or became
     effective (or, if an amendment with respect to any such Incorporated
     Document was filed or

                                       2
<PAGE>
 
     became effective, when such amendment was filed or became effective) with
     the Commission, as the case may be, complied in all material respects with
     the requirements of the 1934 Act and the rules and regulations of the
     Commission under the 1934 Act (the "1934 Act Regulations"), and any
     Incorporated Documents filed subsequent to the date hereof and prior to the
     termination of the offering of the Notes, will, when they are filed with
     the Commission, comply in all material respects with the requirements of
     the 1934 Act and the 1934 Act Regulations; no such Incorporated Document,
     when it was filed or became effective (or, if an amendment with respect to
     any such Incorporated Document was filed or became effective, when such
     amendment was filed or became effective) with the Commission, contained,
     and no Incorporated Document filed subsequent to the date hereof and prior
     to the termination of the offering of the Notes will contain, an untrue
     statement of a material fact or omitted, or will omit, to state a material
     fact required to be stated therein or necessary to make the statements
     therein, in the light of the circumstances under which they were or will be
     made, not misleading.

          (ii)  Each preliminary prospectus relating to the Notes filed as part
     of the Registration Statement as originally filed or as part of any
     amendment thereto, or filed pursuant to Rule 424 of the 1933 Act
     Regulations, when so filed, and the Registration Statement, at the time it
     became effective, complied in all material respects with the provisions
     of the 1933 Act and the 1933 Act Regulations; at the date hereof and at the
     Closing Time, the Registration Statement and the Prospectus, and any
     supplement or amendment thereto relating to the Notes, comply and will
     comply in all material respects with the provisions of the 1933 Act and the
     1933 Act Regulations; and the Registration Statement and the Prospectus,
     and any such supplement or amendment thereto relating to the Notes, at all
     such times did not and will not contain an untrue statement of a material
     fact or omit to state a material fact required to be stated therein or
     necessary to make the statements therein, in the light of the circumstances
     under which they were made, not misleading; except that this representation
     and warranty does not apply to statements or omissions in the Registration
     Statement, the Prospectus or any preliminary prospectus, or any amendment
     or supplement thereto, made in reliance upon information furnished to the
     Company in writing by or on behalf of any Underwriter expressly for use
     therein or to those parts of the Registration Statement that constitute the
     Trustee's Statement of Eligibility on Form T-1 under the 1939 Act (the
     "Form T-1").  There is no contract or document of a character required to
     be described in the Registration Statement or the Prospectus or to

                                       3
<PAGE>
 
     be filed as an exhibit to the Registration Statement that is not described
     or filed as required.

          (iii)  This Agreement, the Indenture and the Notes have been duly
     authorized by the Company and conform in all material respects to the
     descriptions thereof in the Prospectus.

          (iv)  The Indenture (assuming the due execution and delivery thereof
     by the Trustee) is, and the Notes (when executed by the Company and
     authenticated in accordance with the Indenture and delivered to and paid
     for by the purchasers thereof) will be, the legal, valid and binding
     obligations of the Company, enforceable against the Company in accordance
     with their terms, except as such enforceability may be limited by (A)
     bankruptcy, insolvency, reorganization, moratorium or other similar laws
     now or hereafter in effect relating to or affecting the enforcement of
     creditors' rights generally and (B) general principles of equity
     (regardless of whether such enforcement is considered in a proceeding in
     equity or at law). The Notes (when executed by the Company and
     authenticated in accordance with the terms of the Indenture and delivered
     to and paid for by the purchasers thereof) will be entitled to the benefits
     of the Indenture (subject to the exceptions set forth in the preceding
     sentence).

          (v)  The Company and each of Occidental Chemical Holding Corporation,
     a California corporation, and Occidental Oil and Gas Corporation, a
     California corporation (each a "Principal Domestic Subsidiary" and
     collectively the "Principal Domestic Subsidiaries") is a validly existing
     corporation in good standing under the laws of its state of incorporation.
     The Company and each Principal Domestic Subsidiary has full corporate power
     and authority to own its properties and carry on its business as presently
     conducted, as described in the Prospectus, and is duly registered or
     qualified to conduct business, and is in good standing, in each
     jurisdiction in which it owns or leases property or transacts business and
     in which such registration or qualification is necessary, except as to
     jurisdictions where the failure to do so would not have a material adverse
     effect on the Company and its subsidiaries, taken as a whole. All of the
     outstanding capital stock or other securities evidencing equity ownership
     of each Principal Domestic Subsidiary has been duly and validly authorized
     and issued and is fully paid and non-assessable, and is owned by the
     Company, directly or indirectly through subsidiaries, free and clear of any
     security interest, claim, lien or encumbrance. There are no

                                       4
<PAGE>
 
     outstanding rights, warrants or options to acquire, or instruments
     convertible into or exchangeable for, any shares of capital stock or other
     equity interest in any such Principal Domestic Subsidiary, except for
     rights, warrants or options held by the Company.

          (vi)  Except as contemplated in the Prospectus or reflected therein by
     the filing of any amendment or supplement thereto or any Incorporated
     Document, since the date of the most recent consolidated financial
     statements included or incorporated by reference in the Registration
     Statement and the Prospectus, unless the Company has notified the
     Underwriters as provided in Section 4(d) hereof, there has not been any
     material adverse change in the consolidated financial condition of the
     Company and its subsidiaries, taken as a whole.

          (vii)  The Company is not in violation of its Restated Certificate of
     Incorporation or Bylaws, in each case, as amended.  The execution and
     delivery of this Agreement by the Company, the issuance and sale of the
     Notes and the performance by the Company of its obligations under this
     Agreement and the Indenture will not conflict with or constitute a breach
     of or a default (with the passage of time or otherwise) under (A) the
     Restated Certificate of Incorporation or Bylaws of the Company, in each
     case, as amended, (B) any agreement or instrument (which is, individually
     or in the aggregate, material to the Company and its subsidiaries, taken as
     a whole) to which the Company is a party or by which it is bound or (C) any
     order of any court or governmental agency or authority presently in effect
     and applicable to the Company or any Principal Domestic Subsidiary.  Except
     for orders, permits and similar authorizations required under the
     securities or Blue Sky laws of certain jurisdictions, including
     jurisdictions outside the United States, or required of any securities
     exchange on which any of the Notes might be listed, no consent, approval,
     authorization or other order of any regulatory body, administrative agency
     or other governmental body is legally required for the valid issuance and
     sale of the Notes.

          (viii)  To the best of the Company's knowledge, the accountants who
     have audited and reported upon the consolidated financial statements filed
     with the Commission as part of the Registration Statement and the
     Prospectus are independent accountants as required by the 1933 Act.  The
     consolidated financial statements included in the Registration Statement
     and Prospectus, or incorporated therein by reference, fairly present the
     consolidated financial

                                       5
<PAGE>
 
     position and results of operations of the entities to which such statements
     relate at the respective dates and for the respective periods to which they
     apply. Such consolidated financial statements have been prepared in
     accordance with generally accepted accounting principles consistently
     applied, except as set forth in the Registration Statement and Prospectus.

          (ix)  The Company has complied with, and is and will be in compliance
     with, the provisions of that certain Florida act relating to disclosure of
     doing business with Cuba, codified as Section 517.075 of the Florida
     statutes, and the rules and regulations thereunder (collectively, the "Cuba
     Act") or is exempt therefrom.

     (b)  Additional Certifications.  Any certificate signed by any officer of
the Company and delivered to the Underwriters or to counsel for the Underwriters
in connection with transactions contemplated hereby shall be deemed a
representation and warranty by the Company to such Underwriters as to the
matters covered thereby on the date of such certificate.

Section 2.  Sale and Delivery to the Underwriters; Closing.

account, to accept delivery of, and receipt for, and make payment of the

     Japan or to any such resident of Japan, except, in each case, in compliance

     right of rescission, damages or other right as required by applicable
     Canadian Securities Legislation) so that any offer or sale of any of the

Section 4.  Covenants of the Company.

     The Company covenants with each Underwriter as follows:

     (a)  Notice of Certain Events.  During the period from the date hereof to
and including the time at which the distribution of the Notes is completed, the
Company

                                       9
<PAGE>
 
will notify the Underwriters promptly (i) of the effectiveness of any
post-effective amendment to the Registration Statement, (ii) of the receipt of
any comments from the Commission with respect to the Registration Statement or
the Prospectus, (iii) of any request by the Commission for any amendment to the
Registration Statement or any amendment or supplement to the Prospectus or for
additional information and (iv) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement or the
initiation of any proceedings for that purpose.  The Company will make every
reasonable effort to  prevent the issuance of any such stop order and, if any
such stop order is issued, to obtain the lifting thereof at the earliest
possible moment.

     (b)  Proposed Filings.  During the period from the date hereof to and
including the Closing Time, the Company will not file any amendment or
supplement to the Registration Statement, or file any amendment or supplement to
the Prospectus, in any such case relating to the Notes, of which the
Underwriters shall not previously have been advised or to which the Underwriters
shall reasonably object in writing, unless, in the judgment of the Company and
its counsel, such amendment or supplement is necessary to comply with law.

     (c)  Copies of the Registration Statement and the Prospectus.  The Company
will deliver to each of the Underwriters one signed and as many conformed copies
of the Registration Statement (as originally filed) and of each amendment
thereto relating to the Notes (including the Incorporated Documents and any
exhibits filed therewith or incorporated by reference therein) as the
Underwriters may reasonably request.  The Company will furnish to the
Underwriters as many copies of the Prospectus (as amended or supplemented) as
the Underwriters shall reasonably request so long as the Underwriters are
required to deliver a Prospectus in connection with sales or solicitations of
offers to purchase the Notes.

     (d)  Revisions of Prospectus--Material Changes.  So long as the
Underwriters are required to deliver a Prospectus in connection with sales or
solicitations of offers to purchase the Notes, if any event shall occur or
condition exist as a result of which it is necessary, in the opinion of counsel
for the Company and of counsel for the Underwriters, to further amend or
supplement the Prospectus in order that the Prospectus will not include an
untrue statement of a material fact or omit to state any material fact necessary
in order to make the statements therein not misleading, in the light of the
circumstances existing at the time it is delivered to a purchaser, or if it
shall be necessary, in the opinion of such counsel, to amend or supplement the
Registration Statement or the Prospectus in order to comply with the
requirements of 

                                       10
<PAGE>
 
the 1933 Act or the 1933 Act Regulations, prompt notice shall be
given to the Underwriters, and the Company will promptly prepare and file an
amendment or supplement to the Prospectus so that the Prospectus, as amended or
supplemented, will not include any untrue statement of a material fact or omit
to state any material fact necessary in order to make the statements therein not
misleading, in the light of the circumstances existing at the time it is
delivered to the Underwriters.

     (e)  Earnings Statements.  The Company will make generally available to its
security holders a consolidated earnings statement (which need not be audited)
covering a period of at least twelve months commencing after the Closing Time
(but in no event commencing later than 90 days after the Closing Time), as soon
as is reasonably practicable after the end of such period, which earnings
statement shall satisfy the provisions of Section 11(a) and Rule 158 of the 1933
Act.

     (f)  Blue Sky Qualifications.  The Company will endeavor, in cooperation
with the Underwriters, to qualify the Notes for offering and sale under the
applicable securities laws of such states and other jurisdictions as the
Underwriters may reasonably designate (provided no registration shall be
required in any jurisdiction outside the United States), and will maintain such
qualifications in effect for as long as may be required for the distribution of
the Notes; provided, however, that the Company will promptly notify the
Underwriters of any suspension of any such qualifications; and provided,
further, that the Company shall not be obligated to register or qualify as a
foreign corporation or take any action which would subject it to general service
of process in any jurisdiction where it is not now so subject.

     (g)  Filing of Prospectus.  Immediately following the execution and
delivery of this Agreement, the Company will prepare and file or transmit for
filing with the Commission in accordance with Rule 424(b) of the 1933 Act
Regulations, copies of a supplement to the Prospectus containing the terms of
the Notes and such other information as the Underwriters and the Company deem
appropriate.

     [(h)  Listing of Notes.  The Company will use its reasonable best efforts
to cause the Notes to be duly authorized for listing on the New York Stock
Exchange.]

     The Company will pay all expenses incident to the performance of its
obligations under this Agreement, including:

     preparation of any Blue Sky survey and any legal investment survey;

         (vi)   The printing and delivery to the Underwriters in quantities as

     If this Agreement is terminated pursuant to any of the provisions hereof
(otherwise than by notice given by the Underwriters in connection with the
occurrence of any event set forth in clauses (ii) through (iv) of Section 10(a)
or pursuant to Section 11), the Company shall reimburse the Underwriters for all
of their

                                       12
<PAGE>
 
out-of-pocket expenses, including the reasonable fees and disbursements of
counsel for the Underwriters.

Section 6.  Conditions of Underwriters' Obligations.

     The obligations of the Underwriters hereunder are subject to the accuracy
of the representations and warranties on the part of the Company herein and the
accuracy of the statements of the Company's officers made in any certificate
furnished pursuant to the provisions hereof, to the performance and observance
by the Company of all covenants and agreements herein contained on its part to
be performed and observed and to the following additional conditions precedent:

     (a)  At the Closing Time, no stop order suspending the effectiveness of the
Registration Statement shall have been issued and no proceedings for that
purpose shall be instituted or threatened or, to the knowledge of the Company or
any of the Underwriters, contemplated by the Commission; no stop order

prescribed time period, and prior to Closing Time the Company shall have
provided evidence satisfactory to the Underwriters of such timely filing.

     (b)  The Underwriters shall have received an opinion from Robert E. Sawyer,
Esq., Associate General Counsel for the Company, dated as of the Closing Time
and in form and substance satisfactory to counsel for the Underwriters, to the
effect that:

          (i)  The Company has been duly incorporated and is validly existing in
     good standing under the laws of the State of Delaware.  Each Principal
     Domestic Subsidiary is validly existing in good standing under the laws of
     its state of incorporation.

         (ii)  The Company has full corporate power and corporate authority to
     enter into and perform its obligations under this Agreement and the Inden-

                                       13
<PAGE>
 
     ture, to borrow money as contemplated in this Agreement and the Indenture,
     and to issue, sell and deliver the Notes.

          (iii)  This Agreement has been duly authorized, executed and delivered
     by the Company.

          (iv)  The Indenture has been duly authorized, executed and delivered
     by the Company and (assuming the due authorization, execution and delivery
     thereof by the Trustee) is a valid and binding agreement of the Company
     enforceable against the Company in accordance with its terms, except that
     (x) such enforceability may be limited by (A) bankruptcy, insolvency,
     reorganization, moratorium or other similar laws now or hereafter in
     effect relating to creditors' rights generally or (B) general principles of
     equity (regardless of whether enforcement is sought in a proceeding in
     equity or at law) and (y) the waiver contained in Section 515 of the
     Indenture may be deemed unenforceable.

          (v)  No consent or approval of any United States governmental
     authority or other United States person or United States entity is required
     in connection with the issuance or sale of the Notes other than
     registration thereof under the 1933 Act, qualification of the Indenture
     under the 1939 Act, and such registrations or qualifications as may be
     necessary under the securities or Blue Sky laws of the various United
     States jurisdictions in which the Notes are to be offered or sold.  The
     opinion expressed in this paragraph (v) is limited to those consents and
     approvals which, in such counsel's experience, are normally applicable to
     transactions of the type contemplated by this Agreement.

          (vi) The Notes have been duly authorized by the Company and, when
     executed by the Company and authenticated by the Trustee in accordance with
     the terms of the Indenture (assuming the due authorization, execution and
     delivery of the Indenture by the Trustee) and issued to and paid for by the
     Underwriters in accordance with the terms of this Agreement, will be
     entitled to the benefits of the Indenture and will be valid and binding
     obligations of the Company enforceable against the Company in accordance
     with their respective terms, except that (x) such enforceability may be
     limited by (A) bankruptcy, insolvency, reorganization, moratorium or other
     similar laws now or hereafter in effect relating to creditors' rights
     generally or (B) general principles of equity (regardless of whether such
     enforcement is sought in a

                                       14
<PAGE>
 
     proceeding in equity or at law) and (y) the waiver contained in Section 515
     of the Indenture may be deemed unenforceable.

          (vii)  The Registration Statement has become effective under the 1933
     Act and the Indenture has been qualified under the 1939 Act, and, to the
     best of such counsel's knowledge, no stop order suspending the
     effectiveness of the Registration Statement has been issued and no
     proceedings for that purpose have been instituted or are pending or
     contemplated by the Commission.

         (viii)  The execution and delivery of this Agreement and the Indenture
     by the Company, the issuance and sale of the Notes and the performance of
     the Company's obligations under this Agreement and the Indenture will not
     conflict with or constitute a breach of or a default (with the passage of
     time or otherwise) under (A) the Restated Certificate of Incorporation or
     Bylaws of the Company, in each case, as amended, (B) any statute, law or
     regulation to which the Company or any Principal Domestic Subsidiary or any
     of their respective properties may be subject or (C) any judgment, decree
     or order, known to such counsel, after reasonable inquiry, of any court or
     governmental agency or authority entered in any proceeding to which the
     Company or any Principal Domestic Subsidiary was or is now a party or by
     which it is bound, except that such counsel may state that the opinion set
     forth in clause (B) of this paragraph (viii) is limited to those statutes,
     laws or regulations in effect on the date of such opinion which, in such
     counsel's experience, are normally applicable to transactions of the type
     contemplated by this Agreement and that such counsel expresses no opinion
     as to the securities or Blue Sky laws of the various jurisdictions in which
     the Notes are to be offered.

          (ix)   The Registration Statement, as of its effective date, and the
     Prospectus, as of its date, including each Incorporated Document when such
     Incorporated Document was filed or became effective, or if any such
     Incorporated Document was amended, when such amendment was filed or became
     effective, appeared on their face to be appropriately responsive in all
     material respects to the applicable requirements of the 1933 Act or the
     1934 Act, as the case may be, except that in each case such counsel need
     not (x) assume any responsibility for the accuracy, completeness or
     fairness of the statements contained in the Registration Statement or the
     Prospectus or (y) express an opinion as to the financial statements and
     schedules and other financial data

                                       15

     included or incorporated by reference therein or as to the Trustee's
     Statement of Eligibility on Form T-1 under the 1939 Act (the "Form T-1").

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

        (xi)  Except as set forth in the Prospectus (including the
     Incorporated Documents), there is not pending or, to the knowledge of such
     counsel, after reasonable inquiry, threatened any action, suit or
     proceeding against the Company or any of its subsidiaries before or by any
     court or governmental agency or body, which is likely (to the extent not
     covered by insurance) to have a material adverse effect on the consolidated
     financial condition of the Company and its subsidiaries, taken as a whole.

        (xii) To the best of such counsel's knowledge, after reasonable
     inquiry, there is no contract or document of a character required to be
     described in the Registration Statement or the Prospectus or to be filed as
     an exhibit to the Registration Statement that is not described or filed as
     required.

       (xiii) To the best of such counsel's knowledge, after reasonable
     inquiry, the Company is not in violation of its Restated Certificate of
     Incorporation or Bylaws, in each case, as amended.

       (xiv)  To the best of such counsel's knowledge, after reasonable
     inquiry, the execution and delivery of this Agreement and the Indenture by
     the Company, the issuance and sale of the Notes and the performance by the
     Company of its obligations under this Agreement and the Indenture will not
     conflict with or constitute a breach of or a default (with the passage of
     time or otherwise) under any agreement or instrument that is, individually
     or in the aggregate, material to the Company and its subsidiaries, taken as
     a whole, to which the Company is a party or by which it is bound.

          In rendering the opinions set forth in paragraphs (iv) and (vi) above,
     such counsel may state that such enforcement may be limited by (i)
     requirements that a claim with respect to any Notes denominated other than
     in United States dollars (or a judgment denominated other than in United
     States dollars in respect of such claim) be converted into United States
     dollars at a

                                       16
<PAGE>
 
     rate of exchange prevailing on a date determined pursuant to applicable law
     and (ii) governmental authority to limit, delay or prohibit the making of
     payments outside the United States or in foreign currency or composite
     currency.

          In rendering the foregoing opinions such counsel may state that with
     respect to certain matters he has relied upon advice of other counsel 
     employed by the Company who are more familiar with such matters.

          In addition, such counsel shall state that he has participated in
     conferences with officers and other representatives of the Company,
     outside counsel for the Company, representatives of the independent public
     accountants for the Company, representatives of the Underwriters and
     counsel for the Underwriters, at which conferences the contents of the
     Registration Statement and Prospectus and related matters were discussed
     and, although he is not passing upon, and does not assume any
     responsibility for the accuracy, completeness or fairness of the statements
     contained in the Registration Statement or the Prospectus (other than as
     set forth in paragraph (x) above) and has not made any independent check or
     verification thereof, on the basis of the foregoing, nothing has come to
     such counsel's attention that leads him to believe that either the
     Registration Statement (including the Incorporated Documents) at the time
     such Registration Statement became effective, and if an amendment to the
     Registration Statement or an Annual Report on Form 10-K has been filed by
     the Company with the Commission subsequent to the effectiveness of the
     Registration Statement and prior to the date of such statement, then at the
     time such amendment became effective or at the time of the most recent such
     filing (to the extent deemed to be incorporated by reference therein),
     contained an untrue statement of a material fact or omitted to state a
     material fact required to be stated therein or necessary to make the
     statements therein not misleading, or that the Prospectus (including the
     Incorporated Documents) as of its date and as of the Closing Time
     contained or contains an untrue statement of a material fact or omitted or
     omits to state a material fact necessary to make the statements therein, in
     the light of the circumstances under which they were made, not misleading,
     except that such counsel need express no opinion with respect to the
     financial statements, schedules and other financial data included or
     incorporated by reference in the Registration Statement or Prospectus or
     with respect to the Form T-1.

                                       17
<PAGE>
 
     (c)  The Underwriters shall have received an opinion from counsel to the
Underwriters, dated as of the Closing Time and in form and substance
satisfactory to the Underwriters.

     (d)  Officer's Certificate.  Except as contemplated in the Prospectus or
reflected therein by the filing of any amendment or supplement thereto or any
Incorporated Document, at the Closing Time, there shall not have been, since the
date of the most recent consolidated financial statements included or
incorporated by reference in the Prospectus, any material adverse change in the
consolidated financial condition of the Company and its subsidiaries, taken as a
whole.  The Underwriters shall have received a certificate signed by an officer
of the Company, dated as of the Closing Time, to the effect (i) that there has
been no such material adverse change, (ii) that the representations and
warranties of the Company contained in Section 1(a) hereof (other than Section
1(a)(vi)) are true and correct in all material respects with the same force and
effect as though expressly made at and as of the date of such certificate, (iii)
that the Company has complied with all agreements and satisfied all conditions
required by this Agreement or the Indenture on its part to be performed or
satisfied at or prior to the date of such certificate and (iv) that no stop
order suspending the effectiveness of the Registration Statement has been
issued and, to the best of such officer's knowledge, no proceedings for that
purpose have been initiated or threatened by the Commission.

     (e) Comfort Letter.  On the date hereof, the Underwriters shall have
received a letter from the Company's independent public accountants, dated as of
the date hereof and in form and substance satisfactory to the Underwriters,
containing statements and information of a type ordinarily included in
accountants' "comfort letters" to underwriters with respect to the financial
statements and certain financial information contained or incorporated by
reference in the Registration Statement and the Prospectus; and, if financial
statements for any assets, business or entity acquired by the Company are
included or incorporated by reference in the Registration Statement or the
Prospectus, the Underwriters shall have received a similar "comfort letter" from
a firm of independent public accountants, dated as of the date hereof and in
form and substance satisfactory to the Underwriters, with respect to such
financial statements and any financial information with respect to such assets,
business or entity, as the case may be, contained or incorporated by reference
in the Registration Statement and the Prospectus.  Without limitation to the
foregoing, the letter delivered by the Company's independent public
accountants shall state that nothing has come to their attention that caused
them to believe that at a specified date not more than five days prior to the
date of such letter, there was any change in the outstanding 

                                       18
<PAGE>
 
capital stock of the Company or any increase in consolidated long-term debt of
the Company or any decrease in the stockholders' equity of the Company, in each
case as compared with the amounts shown on the most recent consolidated balance
sheet of the Company incorporated by reference in the Registration Statement and
Prospectus or, during the period from the date of such balance sheet to a
specified date not more than five days prior to the date of such letter, there
were any decreases, as compared with the corresponding period in the preceding
year, in consolidated net sales and operating revenues or net income of the
Company, except in each such case as set forth in or contemplated by the
Registration Statement and Prospectus or except for such exceptions enumerated
in such letter as shall have been agreed to by the Underwriters and the Company.

     (f)  Subsequent Delivery of Comfort Letter.  At the Closing Time, the
Underwriters shall have received from each firm of independent public
accountants which delivered a letter pursuant to subsection (e) of this Section,
a letter, dated as of the Closing Time, to the effect that they reaffirm the
statements made in the letter furnished pursuant to subsection (e) of this
Section, except that the specified date referred to shall be a date not more
than five days prior to the Closing Time.

     (g)  Other Documents.  At the Closing Time, counsel for the Underwriters
shall have been furnished with resolutions of the Company's Board of Directors
authorizing and approving the issuance and sale of the Notes and matters related
thereto and such other documents and opinions as they may reasonably require for
the purpose of enabling them to pass upon the issuance and sale of the Notes as
herein contemplated and related proceedings, or in order to evidence the
accuracy of any of the representations or warranties, or the fulfillment of any
of the conditions, herein contained.

     If any condition specified in this Section 6 shall not have been fulfilled
when and as required to be fulfilled, this Agreement may be terminated by any of
the Underwriters by notice to the Company at any time at or prior to the Closing
Time, and any such termination shall be without liability of any party to any
other party, except as provided in Section 5, and except that the indemnity and
contribution agreements set forth in Sections 7 and 8 hereof and the provisions
of Section 9 hereof shall remain in effect.

Section 7.  Indemnification.

                                       19
<PAGE>
 
     (a)  Indemnification of the Underwriters.  The Company agrees to indemnify
and hold harmless each Underwriter and each person, if any, who controls an
Underwriter within the meaning of Section 15 of the 1933 Act as follows:

          (i)  against any and all loss, liability, claim, damage and expense
     whatsoever (including, subject to the limitations set forth in subsection
     (c) below, the reasonable fees and disbursements of counsel chosen by the
     Underwriters), as incurred, insofar as such loss, liability, claim, damage
     or expense arises out of any untrue statement or alleged untrue statement
     of a material fact contained in the Registration Statement or the omission
     or alleged omission therefrom of a material fact required to be stated
     therein or necessary to make the statements therein not misleading, or
     arises out of any untrue statement or alleged untrue statement of a
     material fact contained in the Prospectus or the omission or alleged
     omission therefrom of a material fact necessary in order to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading;

          (ii)  against any and all loss, liability, claim, damage and expense
     whatsoever (including, subject to the limitations set forth in subsection
     (c) below, the reasonable fees and disbursements of counsel chosen by the
     Underwriters), as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever, insofar as such loss, liability, claim, damage or expense
     arises out of any such untrue statement or omission, or any such alleged
     untrue statement or omission, if such settlement is effected with the
     written consent of the Company; and

          (iii)  against any and all expense whatsoever (including, subject to
     the limitations set forth in subsection (c) below, the reasonable fees and
     disbursements of counsel chosen by the Underwriters), as incurred,
     reasonably incurred in investigating, preparing or defending against any
     litigation, or investigation or proceeding by any governmental agency or
     body, commenced or threatened, or any claim whatsoever, based upon any
     such untrue statement or omission, or any such alleged untrue statement or
     omission;

provided, however, that this indemnity shall not apply to any loss, liability,
claim, damage or expense (A) to the extent arising out of or based upon any
untrue statement or omission or alleged untrue statement or omission made in
reliance upon the 

                                       20
<PAGE>
 
Form T-1 under the 1939 Act filed as an exhibit to the Registration Statement;
or (B) to the extent arising out of any untrue statement or omission or alleged
untrue statement or omission in the Prospectus, if such untrue statement or
alleged untrue statement or omission or alleged omission is corrected in an
amendment or supplement to the Prospectus and if, having previously been
furnished by or on behalf of the Company with copies of the Prospectus, as so
amended or supplemented, such Underwriter thereafter failed to deliver such
Prospectus, as so amended or supplemented, prior to or concurrently with the
sale of a Note or Notes to the person asserting such loss, liability, claim,
damage or expense who purchased such Note or Notes that are the subject thereof
from such Underwriter; or (C) as to which such Underwriter may be required to
indemnify the Company pursuant to the provisions of subsection (b) of this
Section 7; or (D) if such loss, liability, claim, damage or expense is covered
by any other written agreement between the Company and such Underwriter
pertaining to the sale of the Notes pursuant to which such Underwriter may be
required to indemnify the Company for such loss, liability, claim, damage or
expense.

     (b)  Indemnification of the Company.  Each Underwriter agrees, severally
and not jointly, to indemnify and hold harmless the Company, its directors, each
of its officers who signed the Registration Statement, and each person, if any,
who controls the Company within the meaning of Section 15 of the 1933 Act
against any and all loss, liability, claim, damage and expense described in the
indemnity contained in subsection (a) of this Section 7, as incurred, but only
with respect to untrue statements or omissions, or alleged untrue statements or
omissions, made in the Registration Statement or the Prospectus in reliance upon
and in conformity with written information furnished to the Company by or on
behalf of any such Underwriter expressly for use in the Registration Statement
or the Prospectus.

     (c)  General.  (i) In case any action, suit or proceeding (including any
governmental or regulatory investigation or proceeding) shall be brought against
any Underwriter or any person controlling such Underwriter, based upon the
Registration Statement or the Prospectus and with respect to which indemnity may
be sought against the Company pursuant to this Section 7, such Underwriter or
controlling person shall promptly notify the Company in writing, and the Company
shall assume the defense thereof, including the employment of counsel and
payment of all expenses.  Any such Underwriter or any such controlling person
shall have the right to employ separate counsel in any such action, suit or
proceeding and to participate in the defense thereof, but the fees and expenses
of such separate counsel shall be at the expense of such Underwriter or such
controlling person, unless (A) the employ-

                                       21
<PAGE>
 
ment of such counsel shall have been specifically authorized in writing by the
Company, (B) the Company shall have failed to assume the defense and employ
counsel or (C) the named parties to any such action, suit or proceeding
(including any impleaded parties) shall include both such Underwriter or such
controlling person and the Company, and such Underwriter or such controlling
person shall have been advised by such counsel that there may be one or more
legal defenses available to it that are different from, or additional to, those
available to the Company (in which case, if such Underwriter or such controlling
person notifies the Company in writing that it elects to employ separate counsel
at the expense of the Company, the Company shall not have the right to assume
the defense of such action, suit or proceeding on behalf of such Underwriter or
such controlling person, it being understood, however, that the Company shall
not, in connection with any one such action or separate but substantially
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the reasonable fees and
expenses of more than one separate firm of attorneys (in addition to any local
counsel) for all such Underwriters and such controlling persons, which firm
shall be designated in writing by a majority of all such Underwriters, on behalf
of all of such Underwriters and such controlling persons).

     (ii) In case any action, suit or proceeding (including any governmental or
regulatory investigation or proceeding) shall be brought against the Company,
any of the Company's directors or officers, or any person controlling the
Company, with respect to which indemnity may be sought against any Underwriter
pursuant to this Section 7, such Underwriter shall have the rights and duties
given to the Company by subsection (c)(i) of this Section 7, and the Company,
the Company's directors and officers and any such controlling person shall have
the rights and duties given to the Underwriters by subsection (c)(i) of this
Section 7.

Section 8.  Contribution.

     In order to provide for just and equitable contribution in circumstances in
which the indemnity agreement provided for in Section 7 hereof is for any reason
held to be unenforceable by the indemnified parties, although applicable in
accordance with its terms, the Company and each Underwriter shall contribute
to the aggregate losses, liabilities, claims, damages and expenses of the nature
contemplated by said indemnity agreement incurred by the Company and the
Underwriters, as incurred, (i) in such proportion as is appropriate to reflect
the relative benefits received by the Company, on the one hand, and each of the
Underwriters, on the other hand, from the offering of the Notes or (ii) if the
allocation provided by clause

                                       22
<PAGE>
 
(i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Company, on the one hand, and of the
Underwriters, on the other hand, in connection with the statements or omissions
that resulted in such losses, liabilities, claims, damages and expenses. The
relative benefits received by the Company, on the one hand, and the
Underwriters, on the other hand, shall be deemed to be in the same proportions
as the total net proceeds from the sale of the Notes (before deducting expenses)
received by the Company, on the one hand, and the total underwriting discounts
and commissions received by each Underwriter, on the other hand, bear to the
total price to public of the Notes as set forth in the table on the cover page
of the Prospectus. The relative fault of the Company, on the one hand, and the
Underwriters, on the other hand, shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company or by the Underwriters and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. The Underwriters' respective obligations to
contribute pursuant to this Section 8 are several in proportion to the
respective numbers of Notes they have purchased hereunder, and not joint.
Notwithstanding the provisions of this Section 8, no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Notes underwritten by it and distributed by the public were
offered to the public exceeds the amount of any damages that such Underwriter
has otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this Section 8, each person, if any, who
controls an Underwriter within the meaning of Section 15 of the 1933 Act shall
have the same rights to contribution as such Underwriter, and each director of
the Company, each officer of the Company who signed the Registration Statement
and each person, if any, who controls the Company within the meaning of Section
15 of the 1933 Act shall have the same rights to contribution as the Company.
Any party entitled to contribution hereunder will, promptly after receipt of
notice of commencement of any action, suit or proceeding against such party in
respect of which a claim for contribution may be made against another party or
parties under this Section 8, notify such party or parties from whom
contribution may be sought, but the omission to so notify such party or parties
shall not relieve the party or parties from whom contribtion may be sought from
any other obligation it or they may have otherwise than under this Section 8.

                                       23
<PAGE>
 
Section 9.  Representations, Warranties and Agreements to Survive Delivery.

     All representations, warranties and agreements contained in this Agreement,
or contained in certificates of officers of the Company submitted pursuant
hereto, shall remain operative and in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or any controlling person
of any Underwriter, or by or on behalf of the Company, and shall survive each
delivery of and payment for any of the Notes.

Section 10.  Termination.

     (a)  The Underwriters may terminate this Agreement, by notice to the
Company, at any time at or prior to the Closing Time if (i) between the date
hereof and the Closing Date, there shall have been any material adverse change
in the consolidated financial condition of the Company and its subsidiaries,
taken as a whole, (ii) there shall have occurred any material adverse change in
the financial markets in the United States or any outbreak or escalation of
hostilities or other national or international calamity or crisis, the effect of
which shall be such as to make it, in the reasonable judgment of the
Underwriters, impracticable to market or to enforce contracts for sale of the
Notes or other debt securities, (iii) trading in any securities of the Company
shall have been suspended by the Commission or a national securities exchange in
the United States, or if trading generally on the New York Stock Exchange shall
have been suspended, or minimum or maximum prices for trading shall have been
fixed, or maximum ranges for prices for securities shall have been required, by
said exchange or by order of the Commission or any other governmental authority,
or if a banking moratorium shall have been declared by either Federal or New
York authorities, (iv) any of Standard & Poor's Corporation, Moody's Investors
Service, Inc., Duff & Phelps Inc. and Fitch IBCA, Inc. (or any of their
respective successors) shall have publicly announced that it has (A) placed the
Notes or the Company's unsecured senior long term debt generally on what is
commonly termed a "watch list" for possible downgrading or (B) downgraded the
Notes or the Company's unsecured senior long term debt generally, or (v) the
Company shall have failed to furnish or cause to be furnished the certificates,
opinions or letters referred to in Section 6 hereof.

     (b)  If this Agreement is terminated pursuant to this Section, such
termination shall be without liability of any party to any other party except as
provided in Section 5.

Section 11.  Default by One or More of the Underwriters.

     If one or more of the Underwriters shall fail at Closing Time to purchase
the Notes which it or they are obligated to purchase under this Agreement (the
"Defaulted Notes"), the non-defaulting Underwriters shall have the right, within
24 hours thereafter, to make arrangements for one or more of such non-defaulting
Underwriters, or any other underwriters, to purchase all, but not less than all,
of the Defaulted Notes in such amounts as may be agreed upon and upon the terms
herein set forth; if, however, such non-defaulting Underwriters shall not have
completed such arrangements within such 24-hour period, then:

          (a)  if the aggregate principal amount of Defaulted Notes does not
     exceed 10% of the aggregate principal amount of the Notes, the non-
     defaulting Underwriters shall be obligated to purchase the full amount
     thereof in the proportions that their respective underwriting obligations
     hereunder bear to the underwriting obligations of all non-defaulting 
     Underwriters, or

          (b)  if the aggregate principal amount of Defaulted Notes exceeds 10%
     of the aggregate principal amount of the Notes, this Agreement shall
     terminate without liability on the part of any non-defaulting Underwriter.

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

     In the event of any such default which does not result in a termination of
this Agreement, either the non-defaulting Underwriters or the Company shall have
the right to postpone the Closing Time for a period not exceeding seven days in
order to effect any required changes in the Registration Statement or Prospectus
or in any other documents or arrangements.

Section 12.  Notices.

     All notices and other communications hereunder shall be in writing and
shall be deemed to have been duly given if mailed or transmitted by any standard
form of telecommunication.  Notices to the Underwriters shall be directed to
them c/o           . Notices to the Company shall be directed to it at 10889
Wilshire Boulevard, Los Angeles, California 90024, attention of Vice President
and Treasurer.

Section 13.  Parties.

     This Agreement shall inure to the benefit of and be binding upon the
Underwriters and the Company and their respective successors. Nothing expressed
or mentioned in this Agreement is intended or shall be construed to give any
person, firm or corporation, other than the parties hereto and their respective
successors and the controlling persons and officers and directors referred to in
Sections 7 and 8 hereof and their heirs and legal representatives, any legal or
equitable right, remedy or claim under or in respect of this Agreement or any
provisions herein contained. This Agreement and all conditions and provisions
hereof are intended to be for the sole and exclusive benefit of the parties
hereto and their respective successors and said controlling persons and officers
and directors and their heirs and legal representatives, and for the benefit of
no other person, firm or corporation. No purchaser of Notes shall be deemed to
be a successor by reason merely of such purchase.

Section 14.  Governing Law.

     This Agreement and the rights and obligations of the parties created hereby
shall be governed by and construed in accordance with the laws of the State of
New York, including without limitation, (S) 5-1401 of the New York General
Obligations Law.

     If the foregoing is in accordance with your understanding of our agreement,
please sign and return to the Company a counterpart hereof, whereupon this
instrument along with all counterparts will become a binding agreement between
the Underwriters and the Company in accordance with its terms.

                              Very truly yours,

                       OCCIDENTAL PETROLEUM CORPORATION

                         MEDIUM-TERM NOTES, SERIES [ ]
                  DUE NINE MONTHS OR MORE FROM DATE OF ISSUE

                        FORM OF DISTRIBUTION AGREEMENT

                                                                          [Date]


Dear Sirs:

     Occidental Petroleum Corporation, a Delaware corporation (the "Company"),
confirms its agreement with each of [insert name of Agents] (each an "Agent" and
collectively, the "Agents") with respect to the issue and sale by the Company of
its Medium-Term Notes, Series [ ] (the "Notes").  The Notes are to be issued
pursuant to the Indenture (the "Indenture," which term, for the purpose of this
Agreement, shall include the Officers' Certificate delivered from time to time
pursuant to Sections 201 and 301 of the Indenture), dated as of April 1, 1998,
between the Company and The Bank of New York, as trustee (the "Trustee").  As of
the date hereof, the Company has authorized the issuance of up to U.S. $
aggregate offering price (or its equivalent, based upon the applicable exchange
rate at the time of issuance, in such foreign currencies, composite currencies
or currency units as the Company shall designate at the time of issuance) of
Notes to be distributed through or sold to the Agents pursuant to the terms of
this Agreement.  It is understood, however, that the Company may from time to
time authorize the issuance of additional Notes and that, at the option of the
Company, such Notes may be distributed through or sold to the Agents pursuant to
the terms of this Agreement, all as though the issuance of such Notes were
authorized as of the date hereof.

     This Agreement provides both for the sale of Notes by the Company to
purchasers, in which case the Agents will act as agents of the Company in
soliciting Note purchasers, and (as may from time to time be agreed to by the
Company and one or more Agents) to such Agent or Agents as principal for resale
to purchasers.

     Subject to the terms and conditions stated herein and subject to the
reservation by the Company of the right to sell Notes directly on its own
behalf and to any
<PAGE>
 
person, and to designate and select additional agents to become parties to this
Agreement, the Company hereby (i) appoints each Agent as an agent of the Com-
pany for the purpose of soliciting offers to purchase the Notes from the Company
by others and (ii) agrees that whenever the Company determines to sell Notes
directly to an Agent as principal for resale to others, it will enter into a
Terms Agreement relating to such sale in accordance with the provisions of
Section 2(b) hereof. Each Agent will make reasonable efforts to assist the
Company in obtaining performance by each purchaser whose offer to purchase Notes
from the Company has been solicited by such Agent, as agent, and accepted by the
Company, but such Agent shall not have any liability to the Company in the event
any such purchase is not consummated for any reason.

     The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 333-      ), and, if
applicable, one or more amendments thereto for the registration of senior debt
securities, including the Notes, under the Securities Act of 1933, as amended
(the "1933 Act"), and the offering thereof from time to time in accordance with
Rule 415 of the rules and regulations of the Commission under the 1933 Act (the
"1933 Act Regulations"). Such registration statement (as amended, if applicable)
has been declared effective by the Commission and the Indenture has been
qualified under the Trust Indenture Act of 1939, as amended (the "1939 Act").
Such registration statement (as amended, if applicable, and any further
registration statements which may be filed by the Company for the purpose of
registering additional Notes and which the Company and the Agents agree is to be
covered by this Agreement) and the prospectus constituting a part thereof,
together with any prospectus supplement relating to the Notes, including, in
each case, all Incorporated Documents (as hereinafter defined), as from time to
time amended or supplemented by the filing of documents pursuant to the
Securities Exchange Act of 1934, as amended (the "1934 Act"), or the 1933 Act or
otherwise, are referred to herein as the "Registration Statement" and the
"Prospectus," respectively, except that, if any revised prospectus or
prospectus supplement shall be provided to the Agents by the Company for use in
connection with the offering of the Notes that is not required to be filed by
the Company pursuant to Rule 424(b) of the 1933 Act Regulations, the term
"Prospectus" shall refer to such revised prospectus or prospectus supplement, as
the case may be, from and after the time it is first provided to the Agents for
such use.  The term "Registration Statement" shall include any related
registration statement filed pursuant to Rule 462(b) of the 1933 Act
Regulations.  Any reference herein to the Registration Statement, any prelimi-
nary prospectus or the Prospectus shall be deemed to refer to and include the
documents, financial statements and schedules incorporated, or deemed to be

                                       2

incorporated, by reference therein pursuant to Item 12 of Form S-3 under the
1933 Act, and any reference to any amendment or supplement to the Registration
Statement or the Prospectus shall be deemed to refer to and include any
documents, financial statements and schedules filed by the Company with the
Commission under the 1934 Act and so incorporated, or deemed to be incorporated,
by reference (such incorporated documents, financial statements and schedules
being herein called the "Incorporated Documents").  Notwithstanding the
foregoing, for purposes of this Agreement any prospectus supplement prepared or
filed with respect to an offering pursuant to the Registration Statement of a
series of debt securities other than the Notes shall not be deemed to have
supplemented the Prospectus.

     hereof and prior to the termination of the offering of the Notes, will,

     Regulations, when so filed, and the Registration Statement, at the time it
     became effective, complied in all material respects with the provisions
     of the 1933 Act and the 1933 Act Regulations; at the applicable

     for use therein or to those parts of the Registration Statement that
     constitute the Trustee's Statement of Eligibility on Form T-1 under the
     1939 Act (the "Form T-1").  There is no contract or document of a character
     required to be described in the Registration Statement or the Prospectus or

          (iii)  This Agreement, the Indenture, the Notes and any applicable

     obligations of the Company, enforceable against the Company in accordance
     with their respective terms, except as such enforceability may be limited

     laws now or hereafter in effect relating to or affecting the enforcement of
     creditors' rights

                                       4

     generally, (B) general principles of equity (regardless of whether such
     enforcement is considered in a proceeding in equity or at law), (C) 
     requirements that a claim with respect to any Notes denominated other than
     in United States dollars (or a judgment denominated other than in United
     States dollars in respect of such claim) be converted into United States
     dollars at a rate of exchange prevailing on a date determined pursuant to
     applicable law and (D) governmental authority to limit, delay or prohibit
     the making of payments outside the United States or in a foreign currency
     or composite currency. The Notes (when executed by the Company and
     authenticated in accordance with the terms of the Indenture and delivered
     to and paid for by the purchasers thereof) will be entitled to the benefits
     of the Indenture (subject to the exceptions set forth in the preceding
     sentence).

          (v)  The Company and each of Occidental Chemical Holding 
     Corporation, a California corporation, and Occidental Oil and Gas
     Corporation, a California corporation, until such time as the fact that any
     such entity is no longer majority owned by the Company shall have been
     disclosed in the Registration Statement and the Prospectus (each a
     "Principal Domestic Subsidiary" and collectively the "Principal Domestic
     Subsidiaries") is a validly existing corporation in good standing under the
     laws of its state of incorporation.  The Company and each Principal
     Domestic Subsidiary has full corporate power and authority to own its
     properties and carry on its business as presently conducted, as described
     in the Prospectus, and is duly registered or qualified to conduct business,
     and is in good standing, in each jurisdiction in which it owns or leases
     property or transacts business and in which such registration or
     qualification is necessary, except as to jurisdictions where the failure to
     do so would not have a material adverse effect on the Company and its
     subsidiaries, taken as a whole.  All of the outstanding capital stock or
     other securities evidencing equity ownership of each Principal Domestic
     Subsidiary has been duly and validly authorized and issued and is fully
     paid and non-assessable, and, except as otherwise disclosed in the
     Registration Statement and the Prospectus, is owned by the Company,

     warrants or options to acquire, or instruments convertible into or
     exchangeable for, any shares of capital stock or other equity interest in
     any such Principal Domestic Subsidiary, except for rights, warrants or
     options held by the Company.

                                       5

          (vi)  Except as contemplated in the Prospectus, since the date of the
     most recent consolidated financial statements included or incorporated by
     reference in the Registration Statement and the Prospectus, unless the Com-
     pany has notified the Agents as provided in Section 3(d) hereof, there has
     not been any material adverse change in the consolidated financial
     condition of the Company and its subsidiaries, taken as a whole.

          (vii)  The Company is not in violation of its Restated Certificate of
     Incorporation or Bylaws, in each case, as amended.  The execution and
     delivery of this Agreement by the Company, the issuance and sale of the
     Notes and the performance by the Company of its obligations under this
     Agreement, the Indenture and any applicable Terms Agreement will not
     conflict with or constitute a breach of or a default (with the passage of
     time or otherwise) under (A) the Restated Certificate of Incorporation or
     Bylaws of the Company, in each case, as amended, (B) subject to the
     Company's compliance with any applicable covenants pertaining to its
     incurrence of unsecured indebtedness contained therein, any agreement or
     instrument (which is, individually or in the aggregate, material to the
     Company and its subsidiaries, taken as a whole) to which the Company is a
     party or by which it is bound or (C) any order of any court or governmental
     agency or authority presently in effect and applicable to the Company or
     any Principal Domestic Subsidiary.  Except for orders, permits and similar
     authorizations required under the securities or Blue Sky laws of certain
     jurisdictions, including jurisdictions outside the United States, or
     required of any securities exchange on which any of the Notes might be
     listed, no consent, approval, authorization or other order of any
     regulatory body, administrative agency or other governmental body is
     legally required for the valid issuance and sale of the Notes.  As of the
     date of each acceptance by the Company of an offer for the purchase of
     Notes and as of the date of each delivery of Notes by the Company, the
     Company by such acceptance or delivery, as the case may be, shall be deemed
     to represent and warrant to the Agents that, both immediately before and
     immediately after giving effect to such acceptance or delivery, the Company
     shall be in compliance with the requirements of any applicable covenants
     pertaining to its incurrence of unsecured indebtedness contained in the
     agreements or instruments referred to in clause (B) above.

          (viii)  To the best of the Company's knowledge, the accountants who
     have audited and reported upon the consolidated financial statements filed
     with the Commission as part of the Registration Statement and the
     Prospectus

                                       6
<PAGE>
 
     are independent accountants as required by the 1933 Act. The consolidated
     financial statements included in the Registration Statement and Prospectus,
     or incorporated therein by reference, fairly present the consolidated
     financial position and results of operations of the entities to which such
     statements relate at the respective dates and for the respective periods to
     which they apply. Such consolidated financial statements have been prepared
     in accordance with generally accepted accounting principles consistently
     applied, except as set forth in the Registration Statement and Prospectus.

          (ix)  The Company has complied with, and is and will be in compli-
     ance with, the provisions of that certain Florida act relating to
     disclosure of doing business with Cuba, codified as Section 517.075 of the
     Florida statutes, and the rules and regulations thereunder (collectively,
     the "Cuba Act") or is exempt therefrom.

     (b)  Additional Certifications.  Any certificate signed by any officer of
the Company and delivered to an Agent or to counsel for the Agents in connection
with an offering of Notes shall be deemed a representation and warranty by the
Company to such Agent as to the matters covered thereby on the date of such
certificate.

SECTION 2.  Solicitations as Agents; Purchases as Principals.

     (a)  Solicitations as Agents.  On the basis of the representations and
warranties herein contained, but subject to the terms and conditions herein set
forth, each Agent agrees, as an agent of the Company, to use its best efforts to
solicit offers to purchase the Notes upon the terms and subject to the
conditions set forth herein and in the Prospectus.  The Agents are not
authorized to appoint sub-agents or to engage the services of any other broker
or dealer in connection with the offer or sale of the Notes as agents.  In
connection with the solicitation of offers to purchase Notes, the Agents are not
authorized to provide any written information relating to the Company to any
prospective purchaser other than the Prospectus and the Incorporated Documents.

     The Company reserves the right, in its sole discretion, to suspend
solicitation of offers to purchase the Notes commencing at any time for any
period of time or permanently.  Upon receipt of instructions from the Company,
the Agents will forthwith suspend solicitation of offers to purchase the Notes
from the Company until such time as the Company has advised the Agents that such
solicitation may be resumed.

                                       7
<PAGE>
 
     The Company agrees to pay each Agent a commission, which such Agent is
hereby authorized to deduct from the sales proceeds of each Note sold by the
Company as a result of a solicitation made by such Agent, equal to the
applicable percentage of the principal amount of each such Note, as set forth in
Exhibit A hereto.  Without the consent of the Company, no Agent may reallow any
portion of the commission payable pursuant hereto to dealers or purchasers in
connection with the offer and sale of any Notes as agents.

     As an agent, each Agent is authorized, except during periods of suspension
as provided in this Agreement, to solicit offers to purchase the Notes.  Each
Agent shall communicate to the Company, orally or in writing, each reasonable
offer to purchase Notes received by such Agent, as agent.  Each Agent shall have
the right in its discretion reasonably exercised to reject any offer to purchase
the Notes received by such Agent that it does not deem reasonable, and any such
rejection shall not be deemed a breach of such Agent's agreements contained
herein.  The Company shall have the sole right to accept offers to purchase the
Notes and may reject any such offer in whole or in part, and any such rejection
shall not be deemed to be a breach of any agreement of the Company contained
herein.  The purchase price, interest rate, maturity date and other terms of the
Notes agreed upon by the Company shall be set forth in a pricing supplement to
the Prospectus to be prepared following each acceptance by the Company of an
offer for the purchase of Notes (a "Pricing Supplement").  All Notes will be
issued at 100% of their principal amount, unless otherwise agreed to by the
Company.  Each Agent acknowledges and agrees that any funds which such Agent
receives in respect of a purchase of Notes, which purchase has been solicited by
such Agent, as agent of the Company, will be received, held and disposed of by
such Agent, as agent of the Company.

     (b)  Purchases as Principal.  Each sale of Notes to an Agent as principal
shall be made in accordance with the terms contained herein and pursuant to a
separate agreement which will provide for the sale of such Notes to, and the
purchase and any reoffering thereof by, such Agent.  Each such separate
agreement (which may be an oral agreement if confirmed within 24 hours
thereafter by an exchange of any standard form of written telecommunication
(including facsimile transmission) between the Agent and the Company) is herein
referred to as a "Terms Agreement." Unless the context otherwise requires, each
reference contained herein to "this Agreement" shall be deemed to include any
applicable Terms Agreement between the Company and the Agent.  Each such Terms
Agreement, whether oral (and confirmed in writing, which confirmation may be by
facsimile transmission) or in writing, shall be with respect to such information
(as applicable) as is specified in

                                       8
<PAGE>
 
Exhibit B hereto. An Agent's commitment to purchase Notes pursuant to any Terms
Agreement shall be deemed to have been made on the basis of the representations
and warranties of the Company herein contained and shall be subject to the terms
and conditions herein set forth. Unless expressly prohibited by the Company
pursuant to the Terms Agreement relating to a sale of Notes to the Agent, each
Agent is authorized to utilize a selling or dealer group in connection with the
resale of the Notes purchased pursuant to such Terms Agreement. In connection
with any brokers or dealers whose services are engaged by any Agent with respect
to the offer or sale of the Notes, such Agent agrees that it will use its best
efforts to cause such brokers or dealers to comply with the terms and provisions
of this Agreement, the applicable provisions of the 1933 Act and the 1934 Act
and the applicable rules and regulations of the Commission thereunder, the
applicable rules and regulations of the National Association of Securities
Dealers, Inc. and the applicable rules of any securities exchange having
jurisdiction over the offering of the Notes.

     (c)  Administrative Procedures.  Administrative procedures with respect to
the sale of Notes shall be agreed upon from time to time by the Agents and the
Company (the "Procedures").  The Procedures initially agreed upon shall be those
set forth in Exhibit C hereto.  The Agents and the Company agree to perform the
respective duties and obligations specifically provided to be performed by the
Agents and the Company herein and in the Procedures.

     (d)  Foreign Offerings.  Each Agent represents and agrees that (i) such
Agent has not solicited, and will not solicit, offers to purchase any of the
Notes from, (ii) such Agent has not sold, and will not sell, any of the Notes
to, and (iii) such Agent has not distributed, and will not distribute, the
Prospectus to, any person or entity in any jurisdiction outside of the United
States (collectively "Foreign Offers and Sales") except, in each case, in
compliance in all material respects with all applicable laws and, in connection
with the initial offering of, or subscription for, any of the Notes, only with
the prior written consent of the Company and in full compliance with any
requirements and procedures established by the Company with respect to any such
Foreign Offers and Sales.  For the purposes of this paragraph, "United States"
means the United States of America, its territories, its possessions (including
the Commonwealth of Puerto Rico) and other areas subject to its jurisdiction.

     In particular and without limiting the generality of the foregoing:

                                       9
<PAGE>
 
          (i)  Each Agent agrees to distribute, in connection with any Foreign
     Offers and Sales, only those Prospectuses used in connection therewith that
     have been appropriately "stickered" for use in the jurisdiction in which
     such Foreign Offers and Sales are to be made.

          (ii)  With respect to the United Kingdom, each Agent represents and
     agrees that (A) it has not offered or sold and will not offer or sell any
     Notes to persons in the United Kingdom except to persons whose ordinary
     activities involve them in acquiring, holding, managing or disposing of
     investments (as principal or agent) for the purposes of their businesses or
     otherwise in circumstances which have not resulted and will not result in
     an offer to the public in the United Kingdom within the meaning of the
     Public Offers of Securities Regulations 1995, (B) it has complied and will
     comply with all applicable provisions of the Financial Services Act of 1986

     and (C) it has only issued or passed on, and will only issue or pass on, in
     the United Kingdom any document received by it in connection with the issue

     document required or permitted to be published by listing rules under Part
     IV of the Financial Services Act, to a person who is of a kind described in
     Article 11(3) of the Financial Services Act 1986 (Investment
     Advertisements) (Exemptions) Order 1996 or is a person to whom such
     document may otherwise lawfully be issued or passed on.

          (iii)  With respect to Japan, each Agent understands that the Notes
     have not been, and will not be, registered under the Securities and
     Exchange Law of Japan, and, accordingly, each Agent represents and agrees
     that (A) in connection with the initial offering of any of the Notes, such
     Agent has not, directly or indirectly, offered or sold, and will not,
     directly or indirectly, offer or sell, any of the Notes in Japan or to any
     resident of Japan (including any corporation or other entity incorporated
     or organized under the laws of Japan), or to others for re-offering or
     resale, directly or indirectly, in Japan or to any such resident of Japan,
     except, in each case, in compliance in all material respects with the
     Securities and Exchange Law of Japan, and (B) with respect to any such sale
     of the Notes made by such Agent, such Agent will effect all necessary
     filings in connection with such sale, including, without limitation, any

          (iv)  With respect to the Provinces of Canada (the "Provinces"), each
     Agent represents and agrees that, in connection with the initial offering
     of any of the Notes, (A) such Agent will not, directly or indirectly, offer
     or sell any of the Notes in any of the Provinces or to, or for the benefit
     of, any resident of any of the Provinces after the date (the "Canadian
     Ending Date") set by the Company for the end of the offer of such Notes,
     and, without the prior written consent of the Company, such Agent will not

     applicable requirements, as prescribed by the Canadian Securities
     Legislation in force at the time when such offer or sale is made, provided
     that such offer or sale is made pursuant to the Prospectus, as supplemented
     to the extent required by the Canadian Securities Legislation (the
     Prospectus, as so supplemented, hereinafter referred to as the "Canadian
     Offering Memorandum"), (C) with respect to Notes offered or sold, or to be
     offered or sold, by such Agent, or Notes purchased, or to be purchased, by
     such Agent, it has provided, and will provide, investors, where required
     pursuant to the provisions of applicable Canadian Securities Legislation,
     with (1) the Canadian Offering Memorandum, and (2) a list of the documents
     filed by the Company with the Commission pursuant to Sections 13(a), 13(c),
     14 or 15(d) of the 1934 Act subsequent to the date of the final Prospectus
     and will obtain from each of such investors an acknowledgment in form
     satisfactory to the Company, and (D) with respect to any such sale of the
     Notes made by such Agent, such Agent will effect all necessary filings in
     connection with such sale, including, without limitation, any required
     filings of (x) reports of trades and (y) the Canadian Offering Memo-

                                       11

     randum, in each case with provincial securities commissions, as required
     pursuant to the provisions of applicable Canadian Securities Legislation.

SECTION 3.  Covenants of the Company.

     The Company covenants with each Agent as follows:

     (a)  Notice of Certain Events.  The Company will notify the Agents promptly
(i) of the effectiveness of any post-effective amendment to the Registration
Statement (other than a post-effective amendment relating solely to an
offering of debt securities other than the Notes), (ii) of the transmittal to
the Commission for filing of any supplement to the Prospectus (other than a
Pricing Supplement or a supplement relating solely to an offering of debt
securities other than the Notes) or any document to be filed pursuant to the
1934 Act which will be incorporated by reference in the Prospectus, (iii) of the
receipt of any comments from the Commission with respect to the Registration
Statement or the Prospectus (other than any comments relating solely to an
offering of debt securities other than the Notes), (iv) of any request by the
Commission for any amendment to the Registration Statement or any amendment or
supplement to the Prospectus or for additional information (other than any such
request relating solely to an offering of debt securities other than the Notes),
(v) of the issuance by the Commission of any stop order suspending the
effectiveness of the Registration Statement or the initiation of any proceedings
for that purpose and (vi) of the receipt of notice from one or more of Standard
& Poor's Corporation, Moody's Investors Service, Inc., Duff & Phelps Inc. and
Fitch IBCA, Inc. (or any of their respective successors) that the Notes have
been or are going to be placed on what is commonly termed a "watch list" for
possible downgrading. The Company will make every reasonable effort to prevent
the issuance of any such stop order and, if any such stop order is issued, to
obtain the lifting thereof at the earliest possible moment, unless the Company
shall, in its sole discretion, determine that it is not in its best interest to
do so.

     (b)  Notice of Certain Proposed Filings.  At or prior to the filing
thereof, the Company will give the Agents notice of its intention to file any
additional registration statement with respect to the registration of
additional Notes to be covered by this Agreement, any amendment to the
Registration Statement or any amendment or supplement to the Prospectus (other
than a Pricing Supplement or an amendment or supplement relating solely to an
offering of debt securities other than the Notes), whether by the filing of
documents pursuant to the 1934 Act, the 1933 Act or

                                       12
<PAGE>
 
otherwise, and will furnish the Agents with copies of any such amendment or
supplement or other documents promptly after the filing thereof.

     (c)  Copies of the Registration Statement and the Prospectus.  The Company
will deliver to the Agents one signed and as many conformed copies of the
Registration Statement (as originally filed) and of each amendment thereto
(including the Incorporated Documents and any exhibits filed therewith or
incorporated by reference therein) as the Agents may reasonably request.  The
Company will furnish to the Agents as many copies of the Prospectus (as amended
or supplemented) as the Agents shall reasonably request so long as the Agents
are required to deliver a Prospectus in connection with sales or solicitations
of offers to purchase the Notes.

     (d)  Revisions of Prospectus--Material Changes.  So long as the Agents are
required to deliver a Prospectus in connection with sales or solicitations of
offers to purchase the Notes, if any event shall occur or condition exist as a
result of which it is necessary, in the opinion of counsel for the Company and
of counsel for the Agents, to further amend or supplement the Prospectus in
order that the Prospectus will not include an untrue statement of a material
fact or omit to state any material fact necessary in order to make the
statements therein not misleading, in the light of the circumstances existing at
the time it is delivered to a purchaser, or if it shall be necessary, in the
opinion of such counsel, to amend or supplement the Registration Statement or
the Prospectus in order to comply with the requirements of the 1933 Act or the
1933 Act Regulations, prompt notice shall be given, and confirmed in writing, to
the Agents to cease the solicitation of offers to purchase the Notes in their
capacity as agents and to cease sales of any Notes the Agents may then own as
principal.  In addition, if any Agent holds Notes purchased for resale pursuant
to a Terms Agreement during the period ending 90 days after the date of
execution of such Terms Agreement, the Company will promptly prepare and file an
amendment or supplement to the Prospectus so that the Prospectus, as amended or
supplemented, will not include any untrue statement of a material fact or omit
to state any material fact necessary in order to make the statements therein not
misleading, in the light of the circumstances existing at the time it is
delivered to the Agents.

     (e)  (Intentionally Omitted).

     (f)  Earnings Statements.  The Company will make generally available to its
security holders, in each case as soon as practicable but in any event not later
than 15 months after the acceptance by the Company of an offer to purchase Notes
hereunder, a consolidated earnings statement (which need not be audited)
covering the

                                       13
<PAGE>
 
twelve-month period beginning after the latest of (i) the effective date of the
Registration Statement, (ii) the effective date of the most recent post-
effective amendment to the Registration Statement to become effective prior to
the date of such acceptance and (iii) the date of the Company's most recent
annual report on Form 10-K filed with the Commission prior to the date of such
acceptance, which earnings statement will satisfy the provisions of Section
11(a) of the 1933 Act (and, at the option of the Company, Rule 158 of the 1933
Act Regulations). Nothing in this Section 3(f) shall require the Company to make
such earnings statement available more frequently than once in any period of
twelve months.

     (g)  Blue Sky Qualifications.  The Company will endeavor, in cooperation
with the Agents, to qualify the Notes for offering and sale under the applicable
securities laws of such states and other jurisdictions as the Agents may
reasonably designate (provided no registration shall be required outside of the
United States), and will maintain such qualifications in effect for as long as
may be required for the distribution of the Notes; provided, however, that the
Company will promptly notify the Agents of any suspension of any such
qualifications; and provided, further, that the Company shall not be obligated
to register or qualify as a foreign corporation or take any action which would
subject it to general service of process in any jurisdiction where it is not
now so subject.

     (h)  Suspension of Certain Obligations.  The Company shall not be required
to comply with the provisions of subsections (b), (c) or (d) of this Section 3
during any period from the time the Agents shall have been notified to suspend
the solicitation of offers to purchase the Notes in their capacity as agent or
resales of Notes purchased pursuant to a Terms Agreement to the time the Company
shall determine that solicitation of offers to purchase the Notes through any
Agent or Agents or resales as principal of Notes purchased pursuant to a Terms
Agreement by any Agent or Agents should be resumed.  Notwithstanding the
foregoing, if any Agent holds Notes purchased for resale pursuant to a Terms
Agreement, the Company shall comply with the provisions of subsections (b), (c)
or (d) of this Section 3 during the 90-day period from and including the date of
execution of such Terms Agreement; provided, however, that the Company shall
have the right, in its reasonable business judgment, to suspend such compliance
during such 90-day period, in which event, such 90-day period shall be extended
by the number of days included in any such period of suspension.

SECTION 4.  Payment of Expenses.

                                       14

     incurred from time to time in connection with the transactions contemplated
     hereby;

         (vi)  The qualification of the Notes under securities laws in

     connection therewith and in connection with the preparation of any Blue Sky
     survey and any legal investment survey;

        (vii)  The printing and delivery to the Agents in quantities as
     hereinabove stated of copies of the Registration Statement and any

     Prospectus and any amendments or supplements thereto in connection with
     solicitations of offers to purchase, or confirmations of sales of, the

          (x)  The fees and expenses, if any, incurred with respect to any
     filing with the National Association of Securities Dealers, Inc. relating
     to the Agents' obligations hereunder or under a Terms Agreement; and

     incurred with the prior written approval of the Company.

SECTION 5.  Conditions of Obligations.

     The obligations of any Agent to solicit offers to purchase the Notes as
agent of the Company and the obligations of any Agent to purchase Notes pursuant
to any Terms Agreement will be subject at all times to the accuracy, as of the
applicable Representation Date, of the representations and warranties on the
part of the Company herein and the accuracy, as of the date made, of the
statements of the Company's officers made in any certificate furnished
pursuant to the provisions hereof, to the performance and observance by the
Company of all covenants and agreements herein contained on its part to be
performed and observed and to the following additional conditions precedent:

     (a)  On the date hereof, the Agents shall have received an opinion from
Robert E. Sawyer, Esq., Associate General Counsel of the Company, dated as of
the date hereof and in form and substance satisfactory to counsel for the
Agents, to the effect that:

          (i)  The Company has been duly incorporated and is validly existing in
     good standing under the laws of the State of Delaware.  Each Principal
     Domestic Subsidiary is validly existing in good standing under the laws of
     its state of incorporation.

         (ii)  The Company has full corporate power and corporate authority to
     enter into and perform its obligations under this Agreement and the
     Indenture, to borrow money as contemplated in this Agreement and the
     Indenture, and to issue, sell and deliver the Notes.

        (iii)  This Agreement has been duly authorized, executed and 
     delivered by the Company.

         (iv)  The Indenture has been duly authorized, executed and delivered
     by the Company and (assuming the due authorization, execution and delivery

                                       16
<PAGE>
 
     thereof by the Trustee) is a valid and binding agreement of the Company
     enforceable against the Company in accordance with its terms, except that
     (x) such enforceability may be limited by (A) bankruptcy, insolvency,
     reorganization, moratorium or other similar laws now or hereafter in
     effect relating to creditors' rights generally or (B) general principles of
     equity (regardless of whether enforcement is sought in a proceeding in
     equity or at law) and (y) the waiver contained in Section 515 of the
     Indenture may be deemed unenforceable.

          (v)  No consent or approval of any United States governmental
     authority or other United States person or United States entity is required
     in connection with the issuance or sale of the Notes other than
     registration thereof under the 1933 Act, qualification of the Indenture
     under the 1939 Act, and such registrations or qualifications as may be
     necessary under the securities or Blue Sky laws of the various United
     States jurisdictions in which the Notes are to be offered or sold.  The
     opinion expressed in this paragraph (v) is limited to those consents and
     approvals which, in such counsel's experience, are normally applicable to
     transactions of the type contemplated by this Agreement.

         (vi)  The Notes have been duly authorized by the Company and, when
     executed by the Company and authenticated by the Trustee in accordance with
     the terms of the Indenture (assuming the due authorization, execution and
     delivery of the Indenture by the Trustee) and issued to and paid for by the
     purchasers thereof, will be entitled to the benefits of the Indenture and
     will be valid and binding obligations of the Company enforceable against
     the Company in accordance with their respective terms, except that (x)
     such enforceability may be limited by (A) bankruptcy, insolvency,
     reorganization, moratorium or other similar laws now or hereafter in effect
     relating to creditors' rights generally or (B) general principles of equity
     (regardless of whether such enforcement is sought in a proceeding in equity
     or at law) and (y) the waiver contained in Section 515 of the Indenture may
     be deemed unenforceable.

        (vii)  The Registration Statement has become effective under the 1933
     Act and the Indenture has been qualified under the 1939 Act, and, to the
     best of such counsel's knowledge, no stop order suspending the
     effectiveness of the Registration Statement has been issued and no
     proceedings for that

                                       17
<PAGE>
 
     purpose have been instituted or are pending or contemplated by the
     Commission.
 
       (viii)  The (x) execution and delivery of this Agreement and the
     Indenture by the Company, (y) issuance and sale of the Notes and (z) 
     performance of the Company's obligations under this Agreement and the
     Indenture will not conflict with or constitute a breach of or a default
     (with the passage of time or otherwise) under (A) the Restated Certificate
     of Incorporation or Bylaws of the Company, in each case, as amended, (B)
     any statute, law or regulation to which the Company or any Principal
     Domestic Subsidiary or any of their respective properties may be subject or
     (C) any judgment, decree or order, known to such counsel, after reasonable
     inquiry, of any court or governmental agency or authority entered in any
     proceeding to which the Company or any Principal Domestic Subsidiary was or
     is now a party or by which it is bound, except that such counsel may state
     that the opinion set forth in clause (B) of this paragraph (viii) is
     limited to those statutes, laws or regulations in effect on the date of
     such opinion which, in such counsel's experience, are normally applicable
     to transactions of the type contemplated by this Agreement and that such
     counsel expresses no opinion as to the securities or Blue Sky laws of the
     various jurisdictions in which the Notes are to be offered.

         (ix) The Registration Statement, as of its effective date, and the
     Prospectus, as of its date, including each Incorporated Document when such
     Incorporated Document was filed or became effective, or if any such 
     Incorporated Document was amended, when such amendment was filed or became
     effective, appeared on their face to be appropriately responsive in all
     material respects to the applicable requirements of the 1933 Act or the
     1934 Act, as the case may be, except that in each case such counsel need
     not (x) assume any responsibility for the accuracy, completeness or
     fairness of the statements contained in the Registration Statement or the
     Prospectus or (y) express an opinion as to the financial statements and
     schedules and other financial data included or incorporated by reference
     therein or as to the Trustee's Statement of Eligibility on Form T-1 under
     the 1939 Act (the "Form T-1").

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

                                       18
<PAGE>
 
         (xi)  Except as set forth in the Prospectus (including the
     Incorporated Documents), there is not pending or, to the knowledge of such
     counsel, after reasonable inquiry, threatened any action, suit or
     proceeding against the Company or any of its subsidiaries before or by any
     court or governmental agency or body, which is likely (to the extent not
     covered by insurance) to have a material adverse effect on the consolidated
     financial condition of the Company and its subsidiaries, taken as a whole.

        (xii) To the best of such counsel's knowledge, after reasonable
     inquiry, there is no contract or document of a character required to be 
     described in the Registration Statement or the Prospectus or to be filed as
     an exhibit to the Registration Statement that is not described or filed as
     required.

       (xiii) To the best of such counsel's knowledge, after reasonable
     inquiry, the Company is not in violation of its Restated Certificate of
     Incorporation or Bylaws, in each case, as amended.

        (xiv) To the best of such counsel's knowledge, after reasonable
     inquiry, the execution and delivery of this Agreement, the Indenture and
     any applicable Terms Agreement by the Company, the issuance and sale of the
     Notes and the performance by the Company of its obligations under this
     Agreement, the Indenture and any applicable Terms Agreement will not
     conflict with or constitute a breach of or a default (with the passage of
     time or otherwise) under, subject (except in respect of any Notes issued
     and sold on the date of such opinion pursuant to an applicable Terms
     Agreement) to the Company's compliance with any applicable covenants
     pertaining to its incurrence of unsecured indebtedness, any agreement or
     instrument that is, individually or in the aggregate, material to the
     Company and its subsidiaries, taken as a whole, to which the Company is a
     party or by which it is bound. To the best of such counsel's knowledge,
     after reasonable inquiry, the issuance and sale as of the date of this
     Agreement of all of the authorized aggregate principal amount of the
     Notes, both immediately before and after giving effect to such issuance and
     sale, would not conflict with or constitute a breach of or a default (with
     the passage of time or otherwise) under any applicable covenants pertaining
     to the Company's incurrence of unsecured indebtedness contained in the
     agreements or instruments referred to above.

          In rendering the opinions set forth in paragraphs (iv) and (vi) above,
     such counsel may state that such enforcement may be limited by (i) require-

                                       19
<PAGE>
 
     ments that a claim with respect to any Notes denominated other than in
     United States dollars (or a judgment denominated other than in United
     States dollars in respect of such claim) be converted into United States
     dollars at a rate of exchange prevailing on a date determined pursuant to
     applicable law and (ii) governmental authority to limit, delay or prohibit
     the making of payments outside the United States or in foreign currency or
     composite currency.

          In rendering the foregoing opinions such counsel may state that with
     respect to certain matters he has relied upon advice of other counsel 
     employed by the Company who are more familiar with such matters.

          In addition, such counsel shall state that he has participated in
     conferences with officers and other representatives of the Company,
     outside counsel for the Company, representatives of the independent public
     accountants for the Company, representatives of the Agents and counsel for
     the Agents, at which conferences the contents of the Registration Statement
     and Prospectus and related matters were discussed and, although he is not
     passing upon, and does not assume any responsibility for the accuracy,
     completeness or fairness of the statements contained in the Registration
     Statement or the Prospectus (other than as set forth in paragraph (x)
     above) and has not made any independent check or verification thereof, on
     the basis of the foregoing, nothing has come to such counsel's attention
     that leads him to believe that either the Registration Statement (including
     the Incorporated Documents) at the time such Registration Statement became
     effective, and if an amendment to the Registration Statement or an Annual
     Report on Form 10-K has been filed by the Company with the Commission
     subsequent to the effectiveness of the Registration Statement and prior to
     the date of such statement, then at the time such amendment became
     effective or at the time of the most recent such filing (to the extent
     deemed to be incorporated by reference therein), contained an untrue
     statement of a material fact or omitted to state a material fact required
     to be stated therein or necessary to make the statements therein not
     misleading, or that the Prospectus (including the Incorporated Documents)
     as of the date of this Agreement (and, if the opinion is being given
     pursuant to Section 6(b) hereof as a result of the Company having entered
     into a Terms Agreement as contemplated by the first paragraph of Section
     6(b) or having filed an Incorporated Document described in the second
     paragraph of Section 6(b), as of the Settlement Date with respect to such
     Terms Agreement or as of the filing date of such Incorporated Document, as
     the case may be)

                                       20
<PAGE>
 
     contained or contains an untrue statement of a material fact or omitted or
     omits to state a material fact necessary to make the statements therein, in
     the light of the circumstances under which they were made, not misleading,
     except that such counsel need express no opinion with respect to the
     financial statements, schedules and other financial data included or
     incorporated by reference in the Registration Statement or Prospectus or
     with respect to the Form T-1.

     (b)  On the date hereof, the Agents shall have received an opinion from
counsel to the Agents, dated as of the date hereof and in form and substance
satisfactory to the Agents.

     (c) Officer's Certificate.  Except as contemplated in the Prospectus or
reflected therein by the filing of any amendment or supplement thereto or any
Incorporated Document, at the date hereof and at each Settlement Date with
respect to any Terms Agreement, there shall not have been, since the date of the
most recent consolidated financial statements included or incorporated by
reference in the Prospectus, any material adverse change in the consolidated
financial condition of the Company and its subsidiaries, taken as a whole.  On
the date hereof (and, if this certificate is being delivered pursuant to a Terms
Agreement, as of the Settlement Date with respect to such Terms Agreement), the
Agents shall have received a certificate signed by an officer of the Company,
substantially in the form of Appendix I hereto and dated the date hereof, to
the effect (i) that there has been no such material adverse change, (ii) that
the representations and warranties of the Company contained in Section 1(a)
hereof (other than Section 1(a)(vi)) are true and correct in all material
respects with the same force and effect as though expressly made at and as of
the date of such certificate, (iii) that the Company has complied with all
agreements and satisfied all conditions required by this Agreement or the
Indenture on its part to be performed or satisfied at or prior to the date of
such certificate and (iv) that no stop order suspending the effectiveness of the
Registration Statements has been issued and, to the best of such officer's
knowledge, no proceedings for that purpose have been initiated or threatened by
the Commission.

     (d) Comfort Letter.  On the date hereof, the Agents shall have received a
letter from the Company's independent public accountants, dated as of the date
hereof and in form and substance satisfactory to the Agents, containing
statements and information of a type ordinarily included in accountants'
"comfort letters" to agents with respect to the financial statements and certain
financial information contained or incorporated by reference in the Registration
Statement and the Pro-

                                       21
<PAGE>
 
spectus; and, if financial statements for any assets, business or entity
acquired by the Company are included or incorporated by reference in the
Registration Statement or the Prospectus, the Agents shall have received a
similar "comfort letter" from a firm of independent public accountants, dated as
of the date hereof and in form and substance satisfactory to the Agents, with
respect to such financial statements and any financial information with respect
to such assets, business or entity, as the case may be, contained or
incorporated by reference in the Registration Statement and the Prospectus.
Without limitation to the foregoing, the letter delivered by the Company's
independent public accountants shall state that nothing has come to their
attention that caused them to believe that at a specified date not more than
five days prior to the date of such letter, there was any change in the
outstanding capital stock of the Company or any increase in consolidated long-
term debt of the Company or any decrease in the stockholders' equity of the
Company, in each case as compared with the amounts shown on the most recent
consolidated balance sheet of the Company incorporated by reference in the
Registration Statement and Prospectus or, during the period from the date of
such balance sheet to a specified date not more than five days prior to the date
of such letter, there were any decreases, as compared with the corresponding
period in the preceding year, in consolidated net sales and operating revenues
or net income of the Company, except in each such case as set forth in or
contemplated by the Registration Statement and Prospectus or except for such
exceptions enumerated in such letter as shall have been agreed to by the Agents
and the Company.

     (e)  Other Documents.  On the date hereof and on each Settlement Date with
respect to any applicable Terms Agreement, counsel to the Agents shall have been
furnished with such documents and opinions as such counsel may reasonably
require for the purpose of enabling such counsel to pass upon the issuance and
sale of the Notes as herein contemplated and related proceedings, or in order to
evidence the accuracy and completeness of any of the representations and
warranties, or the fulfillment of any of the conditions, herein contained.

     If any condition specified in this Section 5 shall not have been fulfilled
when and as required to be fulfilled, this Agreement may be terminated by any of
the Agents (as to itself only) and any Terms Agreement may be terminated by the
Agent party to such Terms Agreement by notice to the Company at any time, and
any such termination shall be without liability of any party to any other party,
except that the covenants set forth in Section 3(f) hereof, the provisions of
Section 4 hereof, the indemnity and contribution agreements set forth in
Sections 7 and 8 hereof and the provisions of Sections 9 and 13 hereof shall
remain in effect.

Statement or the Prospectus shall be amended or supplemented (other than by (i)
a Pricing Supplement or an amendment or other supplement providing solely for a
change in the interest rates of the Notes or changes in other terms of the Notes
or (ii) an amendment or supplement which relates exclusively to an offering of
debt securities other than the Notes) or there is filed with the Commission any
document incorporated, or deemed to be incorporated, by reference into the
Prospectus (other than a Current Report on Form 8-K unless delivery of a
certificate is reasonably requested by the Agents with respect to such filing)
or the Company sells Notes to an Agent pursuant to a Terms Agreement, the terms
of which so require, the Company shall use its best efforts to furnish or cause
to be furnished to the Agents or to the Agent party to the Terms Agreement, as
the case may be, promptly following such amendment, supplement or filing or on
the Settlement Date with respect to such Terms Agreement, as the case may be, a
certificate in form satisfactory to counsel for the Agents to the effect that
the statements contained in the certificate referred to in Section 5(c) hereof
that was last furnished to the Agents are true and correct at the time of such
amendment, supplement, filing or sale, as the case may be, as though made at and
as of such time (except that such statements shall be deemed to relate to the
Registration Statement and the Prospectus as amended and supplemented to such
time) or, in lieu of such certificate, a certificate of the same tenor as the
certificate referred to in said Section 5(c), modified as necessary to relate to
the Registration Statement and the Prospectus as amended and supplemented to the
time of delivery of such certificate.

     (b)  Subsequent Delivery of Legal Opinions.  Each time that the
Registration Statement or the Prospectus shall be amended or supplemented (other
than by (i) a Pricing Supplement or an amendment or other supplement providing
solely for a change in the interest rates of the Notes or changes in other terms
of the Notes, (ii) an amendment or supplement providing solely for the inclusion
of additional financial information or (iii) an amendment or supplement that

Form 10-K, Current Report on Form

<PAGE>
 
8-K or Quarterly Report on Form 10-Q relating primarily to financial statements
or other financial information as of and for any fiscal quarter) or the Company
sells Notes to an Agent pursuant to a Terms Agreement, the terms of which so
require, the Company shall use its best efforts to furnish or cause to be
furnished, promptly following such amendment, supplement or filing or on the
Settlement Date with respect to such Terms Agreement, as the case may be, to the
Agents or to the Agent party to the Terms Agreement, as the case may be, a
letter substantially in the form of Appendix II hereto (modified, as necessary,
in the case of a Terms Agreement) from the counsel last furnishing the opinion
referred to in Section 5(a) hereof or, in lieu of such letter, a letter from
other counsel satisfactory to counsel for the Agents, dated the date of delivery
of such letter and in form satisfactory to counsel for the Agents, of the same
tenor as the opinion referred to in Section 5(a) hereof (other than the matters
covered by Sections 5(a)(viii)(x) and 5(a)(xi)), but modified, as necessary, to
relate to the Registration Statement and the Prospectus, as amended and
supplemented to the time of delivery of such opinion.

     The Company shall use its best efforts to furnish or cause to be furnished
to the Agents, promptly following each filing by the Company of a Quarterly
Report on Form 10-Q or an Annual Report on Form 10-K, a letter from the counsel
last furnishing the opinion referred to in Section 5(a) hereof, or from other
counsel satisfactory to counsel for the Agents, dated the date of delivery of
such letter and in form satisfactory to counsel for the Agents, of the same
tenor as the opinion referred to in Section 5(a)(xi), but modified, as
necessary, to relate to the Registration Statement and Prospectus, as amended
and supplemented to the time of delivery of such letter.

     (c)  Subsequent Delivery of Comfort Letters.  Each time that the
Registration Statement or the Prospectus shall be amended or supplemented to
include additional financial information or there is filed with the Commission
any document incorporated, or deemed to be incorporated, by reference into the
Prospectus which contains additional financial statement information relating to
the Company or the Company sells Notes pursuant to a Terms Agreement, the terms
of which so require, the Company shall use its best efforts to cause the
Company's independent public accountants, promptly following such amendment,
supplement or filing or on the Settlement Date with respect to such Terms
Agreement, as the case may be, to furnish the Agents or to the Agent party to
the Terms Agreement, as the case may be, a letter, dated the date of filing of
such amendment, supplement or document with the Commission, or such Settlement
Date, as the case may be, in form satisfactory to counsel for the Agents (or
such Agent), of the same general tenor as the letter

                                       24
<PAGE>
 
furnished pursuant to Section 5(d) hereof (other than the information required
by the last sentence thereof, except in the case of a Terms Agreement, the terms
of which so require) but modified, as necessary, to relate to the Registration
Statement and Prospectus, as amended and supplemented to the date of such letter
and with such changes as may be necessary to reflect changes in the financial
statements and other information derived from the accounting records of the
Company; provided, however, that if the Registration Statement or the Prospectus
is amended or supplemented solely to include financial information as of and for
a fiscal quarter, the Company's independent public accountants may limit the
scope of such letter to the unaudited financial statements included in such
amendment or supplement.

SECTION 7.  Indemnification.

     (a)  Indemnification of the Agents.  The Company agrees to indemnify and
hold harmless each Agent and each person, if any, who controls an Agent within
the meaning of Section 15 of the 1933 Act as follows:

          (i)  against any and all loss, liability, claim, damage and expense
     whatsoever (including, subject to the limitations set forth in subsection
     (c) below, the reasonable fees and disbursements of counsel chosen by the
     Agents), as incurred, insofar as such loss, liability, claim, damage or
     expense arises out of any untrue statement or alleged untrue statement of a
     material fact contained in the Registration Statement or the omission or
     alleged omission therefrom of a material fact required to be stated therein
     or necessary to make the statements therein not misleading, or arises out
     of any untrue statement or alleged untrue statement of a material fact
     contained in the Prospectus or the omission or alleged omission therefrom
     of a material fact necessary in order to make the statements therein, in
     the light of the circumstances under which they were made, not
     misleading;

          (ii)  against any and all loss, liability, claim, damage and expense
     whatsoever (including, subject to the limitations set forth in subsection
     (c) below, the reasonable fees and disbursements of counsel chosen by the
     Agents), as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever, insofar as such loss, liability, claim, damage or expense
     arises out of any such untrue statement or omission, or any such alleged
     untrue statement or omission, if such settlement is effected with the
     written consent of the Company; and

                                       25
<PAGE>
 
          (iii)  against any and all expense whatsoever (including, subject to
     the limitations set forth in subsection (c) below, the reasonable fees and
     disbursements of counsel chosen by the Agents), as incurred, reasonably
     incurred in investigating, preparing or defending against any litigation,
     or investigation or proceeding by any governmental agency or body,
     commenced or threatened, or any claim whatsoever, based upon any such
     untrue statement or omission, or any such alleged untrue statement or
     omission;

provided, however, that this indemnity shall not apply to any loss, liability,
claim, damage or expense (A) to the extent arising out of or based upon any
untrue statement or omission or alleged untrue statement or omission made in
reliance upon the Form T-1 under the 1939 Act filed as an exhibit to the
Registration Statement; or (B) to the extent arising out of any untrue statement
or omission or alleged untrue statement or omission in the Prospectus, if such
untrue statement or alleged untrue statement or omission or alleged omission is
corrected in an amendment or supplement to the Prospectus and if, having
previously been furnished by or on behalf of the Company with copies of the
Prospectus, as so amended or supplemented, such Agent thereafter failed to
deliver such Prospectus, as so amended or supplemented, prior to or concurrently
with the sale of a Note or Notes to the person asserting such loss, liability,
claim, damage or expense who purchased such Note or Notes that are the subject
thereof from such Agent; or (C) as to which such Agent may be required to
indemnify the Company pursuant to the provisions of subsection (b) of this
Section 7; or (D) if such loss, liability, claim, damage or expense is covered
by any other written agreement between the Company and such Agent pertaining to
the sale of the Notes pursuant to which such Agent may be required to indemnify
the Company for such loss, liability, claim, damage or expense.

     (b)  Indemnification of the Company.  Each Agent agrees, severally and not
jointly, to indemnify and hold harmless the Company, its directors, each of its
officers who signed the Registration Statement, and each person, if any, who
controls the Company within the meaning of Section 15 of the 1933 Act against
any and all loss, liability, claim, damage and expense described in the
indemnity contained in subsection (a) of this Section 7, as incurred, but only
with respect to untrue statements or omissions, or alleged untrue statements
or omissions, made in the Registration Statement or the Prospectus in reliance
upon and in conformity with written information furnished to the Company by or
on behalf of any such Agent expressly for use in the Registration Statement or
the Prospectus.

                                       26
<PAGE>
 
     (c)  General.  (i) In case any action, suit or proceeding (including any
governmental or regulatory investigation or proceeding) shall be brought against
any Agent or any person controlling such Agent, based upon the Registration
Statement or the Prospectus and with respect to which indemnity may be sought
against the Company pursuant to this Section 7, such Agent or controlling person
shall promptly notify the Company in writing, and the Company shall assume the
defense thereof, including the employment of counsel and payment of all
expenses.  Any such Agent or any such controlling person shall have the right to
employ separate counsel in any such action, suit or proceeding and to
participate in the defense thereof, but the fees and expenses of such separate
counsel shall be at the expense of such Agent or such controlling person, unless
(A) the employment of such counsel shall have been specifically authorized in
writing by the Company, (B) the Company shall have failed to assume the defense
and employ counsel or (C) the named parties to any such action, suit or
proceeding (including any impleaded parties) shall include both such Agent or
such controlling person and the Company, and such Agent or such controlling
person shall have been advised by such counsel that there may be one or more
legal defenses available to it that are different from, or additional to, those
available to the Company (in which case, if such Agent or such controlling
person notifies the Company in writing that it elects to employ separate counsel
at the expense of the Company, the Company shall not have the right to assume
the defense of such action, suit or proceeding on behalf of such Agent or such
controlling person, it being understood, however, that the Company shall not, in
connection with any one such action or separate but substantially similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the reasonable fees and expenses of
more than one separate firm of attorneys (in addition to any local counsel) for
all such Agents and such controlling persons, which firm shall be designated in
writing by a majority of all such Agents, on behalf of all of such Agents and
such controlling persons).

     (ii) In case any action, suit or proceeding (including any governmental or
regulatory investigation or proceeding) shall be brought against the Company,
any of the Company's directors or officers, or any person controlling the
Company, with respect to which indemnity may be sought against any Agent
pursuant to this Section 7, such Agent shall have the rights and duties given to
the Company by subsection (c)(i) of this Section 7, and the Company, the
Company's directors and officers and any such controlling person shall have the
rights and duties given to the Agents by subsection (c)(i) of this Section 7.

SECTION 8.  Contribution.
 

                                       27
<PAGE>
 
     In order to provide for just and equitable contribution in circumstances in
which the indemnity agreement provided for in Section 7 hereof is for any reason
held to be unenforceable with respect to the indemnified parties, although
applicable in accordance with its terms, the Company and each Agent shall
contribute to the aggregate losses, liabilities, claims, damages and expenses of
the nature contemplated by said indemnity agreement incurred by the Company
and the Agents, as incurred, (i) in such proportion as is appropriate to reflect
the relative benefits received by the Company, on the one hand, and each of the
Agents, on the other hand, from the offering of the Notes or (ii) if the
allocation provided by clause (i) above is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Company, on
the one hand, and of the Agents, on the other hand, in connection with the
statements or omissions that resulted in such losses, liabilities, claims,
damages and expenses.  The relative benefits received by the Company, on the one
hand, and the Agents, on the other hand, shall be deemed to be in the same
proportions as the total net proceeds from the sale of the Notes (before
deducting expenses) received by the Company, on the one hand, and the total
commissions or other compensation or remuneration received by each Agent, on the
other hand, bear to the total purchase price of the Notes as set forth in the
applicable Pricing Supplement.  The relative fault of the Company, on the one
hand, and the Agents, on the other hand, shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by the Company or by the Agents and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.  The Agents' respective obligations to contribute
pursuant to this Section 8 are several in proportion to the respective principal
amount of Notes they have purchased hereunder, and not joint. Notwithstanding
the provisions of this Section 8, no Agent shall be required to contribute any
amount in excess of the amount by which the total purchase price at which the
Notes were offered by such Agent to the public exceeds the amount of any damages
that such Agent has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933
Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation.  For purposes of this Section 8, each
person, if any, who controls an Agent within the meaning of Section 15 of the
1933 Act shall have the same rights to contribution as such Agent, and each
director of the Company, each officer of the Company who signed the Registration
Statement and each person, if

                                       28
<PAGE>
 
any, who controls the Company within the meaning of Section 15 of the 1933 Act
shall have the same rights to contribution as the Company. Any party entitled to
contribution hereunder will, promptly after receipt of notice of commencement of
any action, suit or proceeding against such party in respect of which a claim
for contribution may be made against another party or parties under this Section
8, notify such party or parties from whom contribution may be sought, but the
omission to so notify such party or parties shall not relieve the party or
parties from whom contribution may be sought from any other obligation it or
they may have otherwise than under this Section 8.

SECTION 9.  Representations, Warranties and Agreements to Survive Delivery.

     All representations, warranties and agreements contained in this Agreement
or any Terms Agreement, or contained in certificates of officers of the Company
submitted pursuant hereto, shall remain operative and in full force and effect,
regardless of any investigation made by or on behalf of any Agent or any
controlling person of any Agent, or by or on behalf of the Company, and shall
survive each delivery of and payment for any of the Notes.

SECTION 10.  Termination.

     (a)  Termination of this Agreement.  This Agreement may be terminated by
the Company (i) for any reason at any time with respect to any Agent or Agents
upon the giving of 10 days' written notice of such termination to each other
party hereto or (ii) at any time upon notice to each other party hereto if no
Notes then remain authorized for sale pursuant hereto.  This Agreement may be
terminated by any Agent (as to itself only) either (x) upon the giving of 10
days' written notice of such termination to each other party hereto or (y) at
any time upon notice to the Company if the Company shall have failed to furnish
or cause to be furnished the certificates, opinions or letters referred to in
Section 5 or 6 hereof or if no Notes then remain authorized for sale pursuant
hereto.

     (b)  Termination of a Terms Agreement.  An Agent party to a Terms 
Agreement may terminate such Terms Agreement (as to itself only) immediately
upon notice to the Company, at any time prior to the Settlement Date relating
thereto, if (i) between the date of such Terms Agreement and the related
Settlement Date, there shall have been any material adverse change in the
consolidated financial condition of the Company and its subsidiaries, taken as a
whole, (ii) there shall have occurred any material adverse change in the
financial markets in the United States or any

                                       29
<PAGE>
 
outbreak or escalation of hostilities or other national or international
calamity or crisis, the effect of which shall be such as to make it, in the
reasonable judgment of such Agent, impracticable to market or to enforce
contracts for sale of the Notes or other debt securities, (iii) trading in any
securities of the Company shall have been suspended by the Commission or a
national securities exchange in the United States, or if trading generally on
the New York Stock Exchange shall have been suspended, or minimum or maximum
prices for trading shall have been fixed, or maximum ranges for prices for
securities shall have been required, by said exchange or by order of the
Commission or any other governmental authority, or if a banking moratorium shall
have been declared by either Federal or New York authorities or if a banking
moratorium shall have been declared by the relevant authorities in the country
or countries of origin of any foreign currency or currencies in which the Notes
are denominated or payable, (iv) any of the nationally recognized securities
rating agencies referred to in Section 3(a)(vi) shall have publicly announced
that it has (A) placed the Notes or the Company's unsecured senior long term
debt generally on what is commonly termed a "watch list" for possible
downgrading or (B) downgraded the Notes or the Company's unsecured senior long
term debt generally, or (v) the Company shall have failed to furnish or cause to
be furnished the certificates, opinions or letters referred to in Section 6
hereof.

     (c)  General.  In the event of any such termination, no party will have any
liability to any other party hereto, except that (i) a terminating Agent shall
be entitled to any commissions earned in accordance with the third paragraph of
Section 2(a) hereof, (ii) if at the time of termination (A) a terminating Agent
and the Company shall have entered into a Terms Agreement and the Settlement
Date with respect thereto shall not yet have occurred or (B) an offer to
purchase any of the Notes has been accepted by the Company but the time of
delivery to the purchaser or his agent of the Note or Notes relating thereto has
not occurred, the covenants set forth in Sections 3 (subject to the provisions
of Section 3(h)) and 6 hereof shall remain in effect until such Settlement Date
or until such Notes are so delivered, as the case may be, (iii) if at the time
of termination an Agent holds Notes purchased under a Terms Agreement entered
into within 90 days of such termination, the covenants set forth in Section 3(d)
(subject to the provisions of Section 3(h)) shall remain in effect for a period
of 90 days following the date such Terms Agreement is entered into (subject to
extension pursuant to Section 3(h)) and (iv) the covenants set forth in Section
3(f) hereof, the provisions of Section 4 hereof, the indemnity and 
contribution agreements set forth in Sections 7 and 8 hereof and the provisions
of Sections 9 and 13 hereof shall remain in effect.

SECTION 11.  Notices.

     All notices and other communications hereunder shall be in writing and
shall be deemed to have been duly given if mailed or transmitted by any standard
form of telecommunication.  Notices to the Agents shall be directed, as the case
may be, to [insert Agent's notice provisions].  Notices to the Company shall be
directed to it at 10889 Wilshire Boulevard, Los Angeles, California 90024,
attention of Vice President and Treasurer.

SECTION 12.  Parties.

     This Agreement shall inure to the benefit of and be binding upon the Agents
(and, in the case of a Terms Agreement, the Agent or Agents party thereto) and
the Company and their respective successors.  Nothing expressed or mentioned in
this Agreement is intended or shall be construed to give any person, firm or
corporation, other than the parties hereto and their respective successors and
the controlling persons and officers and directors referred to in Sections 7 and
8 hereof and their heirs and legal representatives, any legal or equitable
right, remedy or claim under or in respect of this Agreement or any provisions
herein contained.  This Agreement and all conditions and provisions hereof are
intended to be for the sole and exclusive benefit of the parties hereto and
their respective successors and said controlling persons and officers and
directors and their heirs and legal representatives, and for the benefit of no
other person, firm or corporation.  No purchaser of Notes shall be deemed to be
a successor by reason merely of such purchase.


SECTION 13.  Governing Law.

     This Agreement and the rights and obligations of the parties created hereby
shall be governed by and construed in accordance with the laws of the State of
New York, including without limitation, (S) 5-1401 of the New York General

                        OCCIDENTAL PETROLEUM CORPORATION
                         MEDIUM-TERM NOTES, SERIES [ ]
                           ADMINISTRATIVE PROCEDURES


                                                                          [Date]


     The administrative procedures and specific terms of the offering of Medium-
Term Notes, Series [ ] (the "Notes") on a continuous basis by Occidental
Petroleum Corporation (the "Issuer") pursuant to the Distribution Agreement,
dated           (the "Distribution Agreement"), between the Issuer and each of
[Insert Agents] (each an "Agent") are explained below.  In the Distribution
Agreement, the Agents have agreed to use their best efforts to solicit offers to
purchase the Notes. Each Agent, as principal, may purchase Notes for its own
account pursuant to the terms and settlement details of a terms agreement
entered into between the Issuer and such Agent, as contemplated by the
Distribution Agreement.  In the Distribution Agreement, the Issuer reserves the
right to sell Notes directly on its own behalf.

     Each Note will be issued under an indenture between the Issuer and The Bank
of New York, as trustee, (the "Trustee"), dated as of April 1, 1998 (the
"Indenture", which term, for purposes hereof, shall include the Officers'
Certificate (the "Officers' Certificate") delivered from time to time pursuant
to Sections 201 and 301 of the Indenture establishing the terms of the Note),
relating to senior debt securities of the Issuer.  Notes will bear interest at
fixed rates ("Fixed Rate Notes"), floating rates ("Floating Rate Notes") or will
not bear interest.  Each Note will be represented by either a Global Security
(as defined hereinafter) delivered to the Trustee, as agent for The Depository
Trust Company ("DTC"), and recorded in the book-entry system maintained by DTC
(a "Book-Entry Note") or a certificate delivered to the Holder thereof or a
Person designated by such Holder (a "Certificated Note").  Owners of beneficial
interests in a Global Security will be entitled to physical delivery of
Certificated Notes equal in principal amount to their respective beneficial
interests only under certain limited circumstances.

     The Trustee will act as Paying Agent for the payment of principal of and
interest on the Notes and will perform, as Paying Agent, unless otherwise
specified in the Notes, the Indenture or herein, the other duties specified
herein.  Book-Entry Notes will be issued in accordance with the administrative
procedures set forth in Part I hereof, and Certificated Notes will be issued in
accordance with the administrative procedures set forth in Part II hereof. Any
administrative responsibilities, document control and record-keeping functions
to be performed by the Issuer will be performed by its Treasury Department. To
the extent that the procedures set forth herein conflict with any provision of
the Notes (which, in the case of Book-Entry Notes shall be the related Global
Security), the Indenture or the Distribution Agreement, the relevant provisions
of the Notes, the Indenture or the Distribution Agreement shall be controlling.
Unless otherwise defined herein, terms defined in the Indenture, the Officers'
Certificates or the Notes shall be used herein as therein defined.

                              "Settlement" below) for one or more Book-Entry
                              Notes, the Issuer will issue a single global
                              security in fully registered form without coupons
                              (a "Global Security") representing up to
                              $200,000,000 principal amount of all such Notes
                              that have the same Original Issue Price, Stated
                              Maturity, Earliest Redemption Date, Redemption
                              Price and other redemption provisions, if any,

                              Fixed Rate Notes, interest rate and, in the case
                              of Floating Rate Notes, Initial Interest Rate,
                              Base Rate or Rates, Index Maturity, Interest
                              Reset Period, Interest Reset Dates, Spread or
                              Spread Multiplier, if any, Minimum Interest Rate,
                              if any, and Maximum Interest Rate, if any
                              (collectively the "Terms"). Each Global Security
                              will be dated and issued as of the date of its
                              authentication by the Trustee. Each Global
                              Security will bear interest from the later of the
                              Original Issue Date specified therein or from the
                              most recent Interest Payment Date with respect to
                              such Global Security (or Predecessor Security) to
                              which interest has been paid or duly provided for
                              (such later date being herein referred to as a
                              "Global Interest Accrual Date"). Book-Entry Notes
                              may only be denominated and payable in U.S.
                              dollars. No Global Security will represent any
                              Certificated Note.

IDENTIFICATION NUMBERS:       The Issuer has arranged with the CUSIP Service
                              Bureau of Standard & Poor's Corporation (the
                              "CUSIP Service Bureau") for the reservation of a
                              series of CUSIP numbers (including tranche
                              numbers), which series consists of approximately
                              900 CUSIP numbers (of which [ ] remained
                              unassigned as of [ ]) and relates to Global
                              Securities representing the Book-Entry Notes. The
                              Issuer has obtained from the CUSIP Service Bureau
                              a written list of such series of reserved CUSIP
                              numbers and has delivered to

                                      C-2
<PAGE>
 
                              the Trustee and DTC such written list of [ ]
                              unassigned CUSIP numbers. The Issuer will assign
                              CUSIP numbers to Global Securities as described
                              under Settlement Procedure "B" below. DTC will
                              notify the CUSIP Service Bureau periodically of
                              the CUSIP numbers that the Issuer has assigned to
                              Global Securities. At any time when fewer than 100
                              of the reserved CUSIP numbers of a series remain
                              unassigned to Global Securities, the Trustee will
                              notify the Issuer and, if the Issuer deems
                              necessary, it will reserve additional CUSIP
                              numbers for assignment to Global Securities
                              representing Book-Entry Notes. Upon obtaining such
                              additional CUSIP numbers, the Issuer shall deliver
                              a list of such additional CUSIP numbers to the
                              Trustee and DTC.

REGISTRATION:                 Each Global Security will be registered in the
                              name of Cede & Co., as nominee for DTC, on the
                              Security Register maintained under the Indenture.
                              The beneficial owner of a Book-Entry Note (or one
                              or more indirect participants in DTC designated by
                              such owner) will designate one or more
                              participants in DTC (with respect to such Note,
                              the "Participants") to act as agent or agents for
                              such owner in connection with the book-entry
                              system maintained by DTC, and DTC will record in
                              book-entry form, in accordance with instructions
                              provided by such Participants, a credit balance
                              with respect to such Note in the account of such
                              Participants. The ownership interest of such
                              beneficial owner in such Note will be recorded
                              through the records of such Participants or
                              through the separate records of such Participants
                              and one or more indirect participants in DTC.

TRANSFERS:                    Transfers of a Book-Entry Note will be
                              accomplished by book entries made by DTC and, in
                              turn, by Participants (and in certain cases, one
                              or more indirect participants in DTC) acting on
                              behalf of beneficial transferors and transferees
                              of such Note.

EXCHANGES:                    At the request of the Issuer, the Trustee shall
                              deliver to DTC and the CUSIP Service Bureau at any
                              time a written notice of consolidation specifying
                              (i) the CUSIP numbers of two or more Outstanding
                              Global Securities that represent Book-Entry Notes
                              having the same Terms and for which interest has
                              been paid to the same date, (ii) a date, occurring
                              at least 30 days after such written notice is
                              delivered and at least 30 days before the next
                              Interest Payment Date for such Book-Entry Notes,
                              on which such Global Securities shall be exchanged
                              for a single replacement Global Security and (iii)
                              a new CUSIP number, obtained from the Issuer, to
                              be assigned to such replacement Global Security.
                              Upon receipt of such a notice, DTC will send to
                              its Participants (including the Trustee) a written
                              reorganization notice to the effect that such

                                      C-3
<PAGE>
 
                              exchange will occur on such date. Prior to the
                              specified exchange date, the Trustee will deliver
                              to the CUSIP Service Bureau a written notice
                              setting forth such exchange date and the new CUSIP
                              number and stating that, as of such exchange date,
                              the CUSIP numbers of the Global Securities to be
                              exchanged will no longer be valid. On the
                              specified exchange date, the Trustee will exchange
                              such Global Securities for a single Global
                              Security bearing the new CUSIP number, and the
                              CUSIP numbers of the exchanged Global Securities
                              will, in accordance with CUSIP Service Bureau
                              customary procedures, be cancelled and not
                              immediately reassigned. Notwithstanding the
                              foregoing, if the Global Securities to be
                              exchanged exceed $200,000,000 in aggregate
                              principal amount, one Global Security will be
                              authenticated and issued to represent each
                              $200,000,000 of principal amount of the exchanged
                              Global Securities and an additional Global 
                              Security will be authenticated and issued to
                              represent any remaining principal amount of such
                              Global Securities (see "Denominations" below).

MATURITIES:                   Each Book-Entry Note will mature on a date not
                              less than nine months after the settlement date
                              for such Note.

NOTICE OF REDEMPTION
DATES:                        In the case of a full redemption of all Book-Entry
                              Notes represented by a single Global Security,
                              the Trustee will notify DTC not more than 60 but
                              not less than 30 days prior to the Redemption
                              Date with respect to such Global Security, of the
                              CUSIP number of such Global Security, the
                              Redemption Date and the Redemption Price. In the

                              sentence, be represented by a single Global
                              Security, then one Global Security will be issued
                              to represent each $200,000,000 principal amount of

                              Notes shall be assigned the same CUSIP number.

INTEREST:                     General. Interest on each Book-Entry Note will
                              accrue from the Global Interest Accrual Date of
                              the Global Security representing such Note and

                              Global Security representing such Book-Entry Note.
                              In the case of a Global Security originally issued
                              between a Regular Record Date and the related
                              Interest Payment Date or on an Interest Payment
                              Date, the first interest payment will be made on
                              the Interest Payment Date immediately following
                              the next Regular Record Date. Each payment of
                              interest on a Global Security will include
                              interest accrued to but excluding the Interest
                              Payment Date or Maturity. See "Calculation of
                              Interest" below. Interest payable at the Maturity

                              to whom the principal of such Note is payable.

                              Payment Date (other than an Interest Payment Date
                              coinciding with Maturity) and the total of such
                              amounts. DTC will check the amount payable on each

                              such Interest Payment Date, the Issuer will pay to
                              the Trustee the total amount of interest due on
                              such Interest Payment Date (other than at
                              Maturity), and the Trustee will pay such amount to

                              under "Manner of Payment."

                              If any Interest Payment Date for a Fixed Rate 
                              Book-Entry Note is scheduled to occur on a day
                              that is not a Business Day with respect to such
                              Fixed Rate Book-Entry Note, the payment due on
                              such Interest Payment Date will be made on the
                              following day that is a Business Day with respect
                              to such Fixed Rate Book-Entry Note, and no
                              interest shall accrue on the amount payable on
                              such Interest Payment Date for the period from and
                              after such Interest Payment Date to such following

                              If any Interest Payment Date for a Floating Rate
                              Book-Entry Note is scheduled to occur on a day
                              that is not a Business Day with respect to such
                              Floating Rate Book-Entry Note, such Interest
                              Payment Date will be the following day that is a
                              Business Day with respect to such Floating Rate
                              Book-Entry Note; provided, however, that in the
                              case of a Floating Rate Book-Entry Note which is a
                              LIBOR Note, if such following day that is a
                              Business Day is in the next succeeding calendar

                              immediately preceding day that is a Business Day.

                              Payments at Maturity. On or about the first
                              Business Day of each month, the Trustee will

                              principal and interest to be paid on each Global

                              whole or in part) on a Redemption Date or Purchase
                              Date in the following month (to the extent then
                              determinable by the Trustee). The Issuer, the
                              Trustee and DTC will confirm the amounts of such
                              principal and interest payments with respect to
                              each such Global Security on or about the fifth
                              Business Day preceding the Maturity of such
                              Global Security. The Issuer will pay to The Bank
                              of New York, as the Paying Agent, the principal
                              amount of such Global Security, together with
                              interest due at such Maturity. The Paying Agent
                              will pay such amounts to DTC at the times and in
                              the manner set forth under "Manner of Payment"
                              below. If any Maturity of a Global Security
                              representing Book-Entry Notes is not a Business
                              Day, the payment due on such day shall be made on

                                  E.  The Trustee will complete and authenticate
                                      the Global Security representing such

                                  J.  The Trustee will credit to an account of

                              with any extension of Fedwire closing deadlines
                              and in the other events specified in the SDFS
                              operating procedures in effect on the settlement
                              date.

                              If settlement of a Book-Entry Note is rescheduled
                              or cancelled, the Trustee will deliver to DTC,

                              cancellation message to such effect by no later

FAILURE TO SETTLE:            If the Trustee fails to enter an SDFS deliver
                              order with respect to a Book-Entry Note pursuant
                              to Settlement Procedure "G", the Trustee may
                              deliver to DTC, through DTC's Participant Terminal
                              System, as soon as practicable a withdrawal
                              message instructing DTC to debit such Note to the
                              Trustee's participant account. DTC will process
                              the withdrawal message, provided that the
                              Trustee's participant account contains a principal
                              amount of the Global Security representing such
                              Note that is at least equal to the principal
                              amount to be debited. If a withdrawal message is
                              processed with respect to all the Book-Entry Notes
                              represented by a Global Security, the Trustee will
                              mark such Global Security "cancelled", make
                              appropriate entries in the Trustee's records and
                              send such cancelled Global Security to the Issuer.
                              The CUSIP number assigned to such Global Security
                              shall, in accordance with CUSIP Service Bureau
                              customary procedures, be cancelled and not
                              immediately reassigned. If a withdrawal message is
                              processed with respect to one or more, but not
                              all, of the Book-Entry Notes represented by a
                              Global Security, the Trustee will exchange the
                              Global Security for two Global Securities, one of
                              which shall represent such Book-Entry Note or
                              Notes for which such withdrawal message has been
                              processed and shall be cancelled immediately
                              after issuance and the other of which shall
                              represent the remaining Book-Entry Notes
                              previously represented by the surrendered Global
                              Security and shall bear the CUSIP number of the
                              surrendered Global Security.

                              If the purchase price for any Book-Entry Note is
                              not timely paid to the applicable Participants
                              with respect to such Note by the beneficial
                              purchaser thereof (or a Person, including an
                              indirect participant in DTC, acting on behalf of
                              such purchaser), such Participants and, in turn,
                              the Agent for such Note may enter SDFS deliver
                              orders through DTC's Participant Terminal System
                              reversing the orders entered pursuant to
                              Settlement Procedures "H" and "G", respectively.
                              Thereafter, the Trustee will deliver the 
                              withdrawal message and take the related actions
                              described in the preceding paragraph. If such
                              failure shall have occurred for any

                              will reimburse such Agent on an equitable basis
                              for its loss of the use of funds during the period
                              when the funds were credited to the account of the
                              Issuer.

                              Notwithstanding the foregoing, upon any failure to
                              settle with respect to a Book- Entry Note, DTC may
                              take such actions as it deems appropriate in
                              accordance with its SDFS operating procedures
                              then in effect in order to reverse the orders
                              entered into DTC's Participant Terminal System
                              pursuant to Settlement Procedures "H" and "G",
                              respectively. In the event of a failure to settle
                              with respect to one or more, but not all, of the
                              Book-Entry Notes to have been represented by a
                              Global Security, the Trustee will provide, in
                              accordance with Settlement Procedures "D" and "E",
                              for the authentication and issuance of a Global
                              Security representing the other Book-Entry Notes
                              to have been represented by such Global Security
                              and will make appropriate entries in its records.

PROCEDURE FOR POSTINGS:       The Issuer will periodically contact one or more
                              Agents for recommended interest rates, coupons or
                              spreads ("postings") with respect to Notes being
                              offered. When the Issuer has determined or changed
                              its postings with respect to Notes being offered,
                              it will promptly advise the Agents. At such times
                              as the Issuer is not posting, the Agents will not
                              solicit firm offers but may record "indications of
                              interest" only.

PRICING SUPPLEMENTS:          Within five Business Days after any sale of Notes,
                              the Issuer will file or transmit for filing with
                              the Securities and Exchange Commission (the
                              "Commission"), in compliance with Rule 424(b)(3)
                              of the rules and regulations of the Commission
                              promulgated under the Securities Act of 1933, as
                              amended, and Item 309 of Regulation S-T of the
                              Commission, a copy of a pricing supplement to the
                              Prospectus (as defined in the Distribution
                              Agreement) relating to such Notes that reflects
                              the applicable interest rates and other terms (the
                              "Pricing Supplement") and will deliver a copy of
                              such Pricing Supplement to each of the Agents.

SUSPENSION OF SOLICITATION,
AMENDMENT OR SUPPLEMENT:      The Issuer may instruct the Agents to suspend
                              solicitation of purchases of Book-Entry Notes at
                              any time. Upon receipt of such instructions, each
                              Agent will forthwith suspend such solicitations
                              until such time as it has been advised by the
                              Issuer that such solicitations may be resumed. The
                              Issuer will, consistent with its obligations under
                              the Distribution Agreement, promptly advise each
                              Agent and the Trustee whether orders outstanding
                              at the time

<PAGE>
 
                              such Agent suspends solicitation may be settled
                              and whether copies of the Prospectus, as in effect
                              at the time of the suspension, together with the
                              appropriate Pricing Supplement, may be delivered
                              in connection with the settlement of such orders.
                              The Issuer will have the sole responsibility for
                              such decision and for any arrangements that may be
                              made in the event that the Issuer determines that
                              such orders may not be settled or that copies of
                              such Prospectus and Pricing Supplement may not be
                              so delivered.

DELIVERY OF
PROSPECTUS:                   A copy of the most recent Prospectus and of the
                              applicable Pricing Supplement, if any, must be
                              provided to a purchaser by the applicable Agent
                              prior to or at the time of the earlier of (a) the
                              written confirmation of a sale sent to a purchaser
                              of Book-Entry Notes or his Agent, and (b) the date
                              of settlement of any such Book-Entry Notes (see
                              Settlement Procedures).

ADVERTISING COSTS:            The Issuer will determine with the Agents the
                              amount and nature of advertising that may be
                              appropriate in offering the Notes. Advertising
                              expenses approved in writing by the Issuer in
                              connection with the solicitation of purchases of
                              the Notes from the Issuer will be paid by the
                              Issuer.


          PART II:  ADMINISTRATIVE PROCEDURES FOR CERTIFICATED NOTES

     The Trustee will serve as Security Registrar in connection with the
Certificated Notes.

ISSUANCE:                     Each Certificated Note will be dated and issued as
                              of the date of its authentication by the Trustee.
                              Each Certificated Note will bear interest from the
                              later of the Original Issue Date specified therein
                              or from the most recent Interest Payment Date with
                              respect to such Certificated Note (or Predecessor
                              Security) to which interest has been paid or duly
                              provided for (such later date being herein
                              referred to as a "Certificated Interest Accrual
                              Date").

REGISTRATION:                 Certificated Notes will be issued only in fully
                              registered form without coupons.

TRANSFERS AND EXCHANGES:      A Certificated Note may be presented for transfer
                              or exchange at the Corporate Trust Office of the
                              Trustee. Certificated Notes will be exchangeable
                              for other Certificated Notes having identical
                              Terms but different denominations without service
                              charge. Certificated Notes will not be
                              exchangeable for Book-Entry Notes.


                                     C-17
<PAGE>
 
MATURITIES:                   Each Certificated Note will mature on a date not
                              less than nine months from the settlement date for
                              such Note.

DENOMINATIONS:                Certificated Notes will be issued in denominations
                              of $1,000 or any amount in excess thereof that is
                              an integral multiple of $1,000.

INTEREST:                     General. Interest on each Certificated Note will
                              accrue from the Certificated Interest Accrual Date
                              of such Note. In the case of a Certificated Note
                              originally issued between a Regular Record Date
                              and the related Interest Payment Date or on an
                              Interest Payment Date, the first interest payment
                              will be made on the Interest Payment Date
                              following the next Regular Record Date. Each
                              payment of interest on a Certificated Note will
                              include interest accrued to but excluding the
                              Interest Payment Date or Maturity. See
                              "Calculation of Interest" below. Interest will be
                              payable to the Person in whose name a Certificated
                              Note is registered on the Security Register at
                              the close of business on the Regular Record Date
                              next preceding the applicable Interest Payment
                              Date; provided, however, interest payable at
                              Maturity will be payable to the Person to whom
                              principal of such Certificated Note is payable.

                              Regular Record Date. Unless otherwise specified in
                              the applicable Certificated Note, the Regular
                              Record Date with respect to Fixed Rate
                              Certificated Notes shall be the January 15 or July
                              15, as the case may be, next preceding the
                              applicable Interest Payment Date. The Regular
                              Record Date with respect to any Interest Payment
                              Date for Floating Rate Certificated Notes shall be
                              the fifteenth day (whether or not a Business Day)
                              next preceding such Interest Payment Date.

                              Fixed Rate Certificated Notes. Unless otherwise
                              specified in the applicable Certificated Note,
                              interest payments on Fixed Rate Certificated Notes
                              will be made semiannually on February 1 and August
                              1 of each year and at Maturity, subject to the
                              exceptions specified in "Payments of Principal and
                              Interest" below.

                              Floating Rate Certificated Notes. Interest
                              payments will be made on Floating Rate
                              Certificated Notes monthly, quarterly,
                              semiannually or annually of each year, as
                              specified in the related Note, and at maturity.
                              Unless otherwise specified in the applicable
                              Certificated Note and subject to the exceptions
                              specified in "Payments of Principal and Interest"
                              below, interest will be payable, in the case of
                              Floating Rate Certificated Notes which reset (i)
                              daily, weekly or monthly, on the third Wednesday
                              of each month; (ii)


                                     C-18
<PAGE>
 
                              quarterly, on the third Wednesday of March, June,
                              September and December of each year; (iii)
                              semiannually, on the third Wednesday of each of
                              the two months specified in the applicable 
                              Certificated Note; and (iv) annually, on the third
                              Wednesday of the month specified in the applicable
                              Certificated Note and, in each case, at Maturity.

CALCULATION OF
INTEREST:                     Fixed Rate Certificated Notes. Unless otherwise
                              specified in the applicable Certificated Note,
                              interest on Fixed Rate Certificated Notes
                              (including interest for partial periods) will be
                              calculated on the basis of a 360-day year of
                              twelve 30-day months.

                              Floating Rate Certificated Notes. Interest rates
                              on Floating Rate Certificated Notes will be
                              determined as set forth in the applicable Notes.
                              The Issuer and the Trustee will confirm the amount
                              of the initial interest payment due on any
                              Floating Rate Certificated Note for which the
                              initial Interest Period is shorter or longer than
                              the Index Maturity. Promptly after each Interest
                              Determination Date for Floating Rate Certificated
                              Notes, the Calculation Agent will notify Standard
                              & Poor's Corporation of the interest rates
                              determined on such Interest Determination Date.
                              Unless otherwise specified in the applicable
                              Certificated Note, interest will be calculated in
                              the case of (a) Commercial Paper Rate, CD Rate,
                              Federal Funds Rate, LIBOR and Prime Rate
                              Certificated Notes, on the basis of the actual
                              number of days in the interest period and a 360-
                              day year; and (b) Treasury Rate Notes, on the
                              basis of the actual number of days in the interest
                              period and the actual number of days in the year.

PAYMENTS OF PRINCIPAL
AND INTEREST:                 The Trustee will pay the principal amount of each
                              Certificated Note at Maturity to the Person in
                              whose name such Note is registered upon
                              presentation of such Note to the Trustee. Such
                              payment, together with payment of interest due at
                              Maturity of such Note, will be made in funds
                              available for immediate use by the Holder of such
                              Note. Certificated Notes presented to the Trustee
                              at Maturity for payment will be cancelled by the
                              Trustee in accordance with the terms of the
                              Indenture and returned to the Issuer. All interest

                              drawn on the Trustee (or another Person appointed
                              by the Trustee) and mailed by the Trustee to the

                              If any Interest Payment Date for a Fixed Rate
                              Certificated Note is scheduled to occur on a day
                              that is not a Business Day with respect to such

                              such Interest Payment Date for the period from and

                              that is not a Business Day with respect to such
                              Floating Rate Certificated Note, such Interest

                              If the date of Maturity of a Certificated Note is
                              scheduled to occur on a day that is not a Business
                              Day with respect to such Certificated Note, the

                              following day that is a Business Day with respect
                              to such Certificated Note, and no interest shall
                              accrue on the amount payable at Maturity for the
                              period from and after the date of Maturity.

FAILURE TO SETTLE:            If a purchaser fails to accept delivery of and
                              make payment for any Certificated Note, the
                              selling Agent will notify the Issuer and the
                              Trustee by telephone and return such Note to the

                              will immediately wire transfer to the account of
                              the Agent an amount equal to the amount previously

<PAGE>
 
                              wire transfer will be made on the settlement date,
                              if possible, and in any event not later than the
                              day following the settlement date. If the failure
                              shall have occurred for any reason other than a
                              default by the applicable Agent in the performance
                              of its obligations hereunder and under the
                              Distribution Agreement, the Issuer will reimburse
                              such Agent on an equitable basis for its loss of
                              the use of the funds during the period when they
                              were credited to the account of the Issuer.
                              Immediately upon receipt of the Certificated Note
                              in respect of which such failure occurred, the
                              Trustee will mark such Note "cancelled", make
                              appropriate entries in the Trustee's records and
                              send such cancelled Note to the Issuer.

PROCEDURE FOR POSTINGS:       The Issuer will periodically contact one or more
                              Agents for recommended postings with respect to
                              Certificated Notes being offered. When the Issuer
                              has determined or changed its postings with
                              respect to Certificated Notes being offered, it
                              will promptly advise the Agents. At such times as
                              the Issuer is not posting, the Agents will not
                              solicit firm offers but may record "indications of
                              interest" only.

PRICING SUPPLEMENTS:          Within five Business Days after any sale of
                              Certificated Notes, the Issuer will file or
                              transmit for filing with the Commission in
                              compliance with Rule 424(b)(3) of the rules and
                              regulations of the Commission promulgated under
                              the Securities Act of 1933, as amended, and Item
                              309 of Regulation S-T of the Commission, a copy of
                              a Pricing Supplement to the Prospectus relating to
                              such Notes that reflects the applicable interest
                              rates and other terms and will deliver a copy of
                              such Pricing Supplement to each of the Agents.

SUSPENSION OF SOLICITATION,
AMENDMENT OR SUPPLEMENT:      The Issuer may instruct the Agents to suspend
                              solicitation of purchases of Certificated Notes at
                              any time. Upon receipt of such instructions, each
                              Agent will forthwith suspend such solicitations
                              until such time as it has been advised by the
                              Issuer that such solicitations may be resumed. The
                              Issuer will, consistent with its obligations under
                              the Distribution Agreement, promptly advise each
                              Agent and the Trustee whether orders outstanding
                              at the time such Agent suspends solicitation may
                              be settled and whether copies of the Prospectus,
                              as in effect at the time of the suspension,
                              together with the appropriate Pricing Supplement,
                              may be delivered in connection with the
                              settlement of such orders. The Issuer will have
                              the sole responsibility for such decision and for
                              any arrangements that may be made in the event
                              that the Issuer determines that such orders may
                              not be settled or that copies of such Prospectus
                              and Pricing Supplement may not be so delivered.

If Securities of a series are issuable as Bearer Securities, any request,
demand, 

                                       10
<PAGE>
 
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Holders of such series may,
alternatively, be embodied in and evidenced by the record of Holders of
Securities of such series voting in favor thereof, either in person or by
proxies duly appointed in writing, at any meeting of Holders of Securities of
such series duly called and held in accordance with the provisions of Article
Thirteen, or a combination of such instruments and any such record. Except as
herein otherwise expressly provided, such action shall become effective when
such instrument or instruments or record or both are delivered to the Trustee
and, where it is hereby expressly required, to the Company. Such instrument or
instruments and any such record (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments and so voting at any such meeting. Proof of
execution of any such instrument or of a writing appointing any such agent, or
of the holding by any Person of a Security, shall be sufficient for any purpose
of this Indenture and (subject to Section 601) conclusive in favor of the
Trustee and the Company, if made in the manner provided in this Section. The
record of any meeting of Holders of Securities shall be proved in the manner
provided in Section 1306.

instrument or writing, or the authority of the Person executing the same, may be
proved in any reasonable manner which the Trustee deems sufficient.

by any Person, and the date of holding the same, shall be proved by the Security
Register.

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

     (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.

     (f)  If the Company shall solicit from the Holders any request, demand,
authorization, direction, notice, consent, waiver or other Act, the Company may,
at its option, by or pursuant to an Officers' Certificate delivered to the
Trustee, fix in advance a record date for the determination of Holders entitled
to give such request, demand, authorization, direction, notice, consent, waiver
or other Act, but the 

                                       11
<PAGE>
 
Company shall have no obligation to do so. Any such record date, if so fixed,
may vary from that specified in Section 316(c) of the Trust Indenture Act. If
such a record date is fixed, such request, demand, authorization, direction,
notice, consent, waiver or other Act may be given before or after such record
date, but only the Holders of record at the close of business on such record
date shall be deemed to be Holders for the purposes of determining whether
Holders of the requisite percentage of Outstanding Securities or Outstanding
Securities of a series, as the case may be, 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
Outstanding Securities of the series, as the case may be, shall be computed as
of such record date; provided, that no such authorization, agreement or consent
by the Holders on the record date shall be deemed effective, unless such
request, demand, authorization, direction, notice, consent, waiver or other Act
shall become effective pursuant to the provisions of Clause (a) of this Section
104 not later than six months after the record date.

Section 105.  Notices, Etc., to Trustee and Company.

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 Trustee 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, Attention: Treasurer, at the address of its principal
     office specified in the first paragraph of this instrument or at any other
     address previously furnished in writing to the Trustee by the Company.

Section 106.  Notice to Holders; Waiver.

     Except as otherwise expressly provided herein, where this Indenture

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

          (2)  such notice shall be sufficiently given to Holders of Bearer
     Securities, if published in an Authorized Newspaper in The City of New York
     and in such other city or cities as may be specified in such Securities on
     a Business Day at least twice, the first such publication to be not earlier
     than the earliest date, and not later than the latest date, prescribed for
     the giving of such notice.

     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 

                                       12
<PAGE>
 
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 to Holders of
Registered Securities by mail, then such notification as shall be made with the
approval of the Trustee shall constitute a sufficient notification for every
purpose hereunder.  In any case where notice to Holders of Registered Securities
is given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder of a Registered Security shall affect
the sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice to Holders of Bearer Securities
given as provided herein.

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

     In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security or, in the case of any Security which is subject to
redemption or repurchase by the Company at the option of the Holder, the date
fixed for such redemption or repayment, shall not be a Business Day at any Place
of Payment, then, except as may otherwise be provided with respect to the
Securities of any series pursuant to Section 301, payment of interest or
principal 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 or the date fixed for such redemption or repurchase, and
no interest shall accrue for the period from and after such Interest Payment
Date, Redemption Date or Stated Maturity or date for such redemption or
repurchase, as the case may be.

Section 114.  Language of Notices, Etc.

Section 201.  Forms Generally.

     The Registered Securities, if any, of each series and the Bearer
Securities, if any, and the coupons, if any, appertaining thereto, of each
series shall be in such form (including global form) as shall be established by
delivery to the Trustee of an Officers' Certificate or in one or more indentures
supplemental hereto, in each case with such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by this
Indenture, and may have such letters, numbers or other marks of identification
and such legends or endorsements placed thereon as may be required to comply
with the rules of any securities exchange or as may, consistently herewith, be
determined by the officers executing such Securities or coupons, as evidenced by
their execution of the Securities or coupons.  If the forms of the Securities or
coupons of any series are established by an Officers' Certificate, such
Officers' Certificate shall be delivered to the Trustee at or prior to the
delivery of the Company Order contemplated by Section 303 for the authentication
and delivery of such Securities or coupons.

     Unless otherwise specified as contemplated by Section 301, Bearer
Securities shall have interest coupons attached.

     The definitive Securities and coupons, if any, shall be printed,
lithographed or engraved or produced by any combination of these methods or may
be produced in any other manner, provided, that such method is permitted by the
rules of any securities exchange on which such Securities may be listed, all as
determined by the officers executing such Securities, as evidenced by their
execution of such Securities.

Section 202.  Form of Trustee's Certificate of Authentication.

     The Trustee's certificate of authentication shall be in substantially the
following form:

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

                              The Bank of New York,
                                as Trustee

                              By: . . . . . . . . . . . . . . . . . . . . . . .
                                    Authorized Signatory

Section 203.  Securities in Global Form.

     If Securities of a series are issuable in temporary or definitive global
form, as specified as contemplated by Section 301, then, notwithstanding Clause
(10) of Section 301 and the provisions of Section 302, any such Security shall
represent such of the Outstanding Securities of such series as shall be
specified therein and may provide that it shall represent the aggregate amount
of Outstanding Securities from time to time endorsed thereon and that the
aggregate amount of Outstanding Securities represented thereby may from time to
time be reduced to reflect exchanges.  Any endorsement of a Security in global
form to reflect the amount, or any increase or decrease in the amount, of
Outstanding Securities represented thereby shall be made by the Trustee in such
manner, and upon instructions given by such Person or Persons, as shall be
specified therein or in the Company Order to be delivered to the Trustee
pursuant to Section 303 or Section 304.  Subject to the provisions of Section
303 and, if applicable, Section 304, the Trustee shall deliver and redeliver any
Security in global form in the manner, and upon instructions given by the Person
or Persons, specified therein or in the applicable Company Order.  If a Company
Order pursuant to Section 303 or 304 has been, or simultaneously is, delivered,
any instructions by the Company with respect to endorsement, or delivery or
redelivery, of a Security in global form shall be in writing, but need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel.

     The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Security in global form, if such Security was never
issued and sold by the Company, and the Company delivers to the Trustee the
Security in global form, together with written instructions (which need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel)
with regard to the 

                                       15
<PAGE>
 
reduction in the principal amount of Securities represented thereby and the
written statement contemplated by the last sentence of Section 303.

     Authorized Newspapers for publication of notices to holders of Bearer
     Securities;

     interest shall be payable and the Regular Record Date for any interest
     payable on any Registered Securities on any Interest Payment Date;

     1002, the principal of and any interest on Securities of the series shall
     be payable, any Registered Securities of the series may be surrendered for
     registration of transfer, Securities of the series may be surrendered for
     exchange and notices and demands to or upon the Company in respect of the
     Securities of the series and this Indenture may be served;

          (9)  the obligation, if any, of the Company to redeem or purchase
     Securities of the series pursuant to any sinking fund or analogous

     denominations of $5,000 and $100,000;

          (11)  the currency or currencies, including composite currencies or
     currency units, in which Securities of the series may be denominated or in
     which payment of the principal of and any interest on the Securities of the
     series shall be payable, if other than the currency of the United States of
     America, and if so, whether the Securities of the series may be satisfied
     and discharged other than as provided in Article Four;

          (12)  if the amounts of payments of principal of and any interest on
     the Securities of the series are to be determined with reference to an
     index, formula or other method, or based on a coin or currency other than
     that in which the Securities are stated to be payable, the manner in which
     such amounts shall be determined and the calculation agent, if any, with
     respect thereto;

          (13)  if other than the principal amount thereof, the portion of the
     principal amount of any Securities of the series which shall be payable

     United States Holder (including any modification in the definition of such
     term), in respect of any tax, assessment or governmental charge withheld or
     deducted, under what circumstances, and with what procedures and
     documentation, the Company will pay such additional amounts, whether such
     additional amounts will be treated as interest or principal pursuant to
     this Indenture, and whether the Company will have the option to redeem such
     Securities rather than pay additional amounts (and the terms of any such
     option);

          (15)  if other than as defined in Section 101, the meaning of
     "Business Day" when used with respect to any Securities of the series;

          (16)  if the Securities of the series may be issued or delivered
     (whether upon original issuance or upon exchange of a temporary Security of
     such series or otherwise), or any installment of principal or interest is
     payable, only upon receipt of certain certificates or other documents or
     satisfaction of other conditions in addition to those specified in this
     Indenture, the forms and terms of such certificates, documents or
     conditions;

          (17)  any addition to, or modification or deletion of, any Event of
     Default, covenant of the Company or other term or provision specified in
     this Indenture with respect to Securities of the series;

          (18)  any other terms of the series, whether or not consistent with
     the other provisions of this Indenture.

     All Securities of any one series and the coupons appertaining to any Bearer
Securities of such series shall be substantially identical, except as to
denomination, the rate or rates of interest, if any, the Stated Maturity, the
date from which interest, if any, shall accrue, the other financial terms
thereof and except as may otherwise be provided in or pursuant to an Officers'
Certificate pursuant to this Section 301 or in any indenture supplemental
hereto.  All Securities of any one series need not be issued at the same time
and, unless otherwise provided, a series may be reopened for issuances of
additional Securities of such series.

     If any of the terms of the series are established by action taken pursuant
to a Board Resolution, a copy of any appropriate record of 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.  With respect to Securities
of a series subject to a Periodic Offering, such Board Resolution or the
Officers' Certificate or supplemental indenture setting forth or establishing
the terms of such series may provide general terms for Securities of such series
and provide either that the specific terms of particular Securities of such
series shall be specified in a Company Order or that such terms shall be
determined by the Company, or one or more of the Company's agents designated in
an Officers' Certificate, in accordance with the Company Order as contemplated
by the first proviso of the third paragraph of Section 303.

Section 302.   Denominations.

                                       18
<PAGE>
 
     Unless otherwise provided as contemplated by Section 301 with respect to
any series of Securities, any Registered Securities of a series shall be
issuable in denominations of $1,000 and any integral multiple thereof and any
Bearer Securities of a series shall be issuable in denominations of $5,000 and
$100,000.

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, one of its Vice Presidents, its Treasurer, or one
of its Assistant Treasurers under its corporate seal (or a facsimile thereof)
reproduced thereon and 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. Coupons shall bear the actual or facsimile signature of the
Treasurer or an Assistant Treasurer of the Company.

     Securities and coupons, if any, appertaining thereto, 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, together with any
coupons appertaining thereto, 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 such Company
Order, shall authenticate and deliver such Securities; provided, however, that,
with respect to Securities of a series subject to a Periodic Offering, (a) such
Company Order may be delivered by the Company to the Trustee prior to the
delivery to the Trustee of such Securities for authentication and delivery, (b)
the Trustee shall authenticate and deliver Securities of such series for
original issue from time to time, in an aggregate principal amount not exceeding
the aggregate principal amount established for such series, pursuant to a
Company Order or pursuant to such procedures acceptable to the Trustee as may be
specified from time to time by a Company Order, (c) the rate or rates of
interest, if any, the Stated Maturity or Maturities, the original issue date or
dates, the redemption provisions, if any, and any other terms of Securities of
such series shall be determined by a Company Order or pursuant to such
procedures and (d) if provided for in such procedures, such Company Order may
authorize authentication and delivery pursuant to oral or electronic
instructions from the Company, or the Company's duly authorized agent or agents
designated in an Officers' Certificate, which oral instructions shall be
promptly confirmed in writing; and provided, further, that, in connection with
its original issuance, no Bearer Security or coupon shall be mailed or otherwise
delivered to any Person who is not a Non-United States Holder or to any location
in the United States.  Except as permitted by Section 306, the Trustee shall not
authenticate and deliver any Bearer Security, unless all appurtenant coupons for
interest then matured have been detached and cancelled.

     In authenticating Securities, the form or terms of which have been
established in or pursuant to one or more Officers' Certificates as permitted by
Sections 201 and 301, and accepting the additional responsibilities under this
Indenture in relation to such Securities, the Trustee shall be entitled to
receive, and (subject to Section 601) shall be fully protected in relying upon,
an Opinion of Counsel stating:

                                       19
<PAGE>
 
          (a)  that the form and terms of such Securities, including any
     coupons, have been duly authorized by the Company and established in
     conformity with the provisions of this Indenture; and

          (b)  that such Securities, together with any coupons appertaining
     thereto, when authenticated and delivered by the Trustee and issued by the
     Company in the manner and subject to any conditions specified in such
     Opinion of Counsel, will constitute valid and legally binding obligations
     of the Company, enforceable in accordance with their terms, subject to
     customary exceptions;

provided, however, that, with respect to Securities of a series subject to a
Periodic Offering, the Trustee shall be entitled to receive such Opinion of
Counsel only once, at or prior to the time of the first authentication of
Securities of such series, and that the Opinion of Counsel above may state:

          (x)  that the forms of such Securities have been, and the terms of
     such Securities (when established in accordance with such procedures as may
     be specified from time to time in a Company Order, all as contemplated by
     and in accordance with a Board Resolution or an Officers' Certificate
     pursuant to Section 301, as the case may be) will have been, duly
     authorized by the Company and established in conformity with the provisions
     of this Indenture; and

          (y)  that such Securities, together with the coupons, if any,
     appertaining thereto, when (1) executed by the Company, (2) completed,
     authenticated and delivered by the Trustee in accordance with this
     Indenture and (3) 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 customary exceptions.

     With respect to Securities of a series subject to a Periodic Offering, the
Trustee may conclusively rely, as to the authorization by the Company of any of
such Securities, the form and terms thereof and the legality, validity, binding
effect and enforceability thereof, upon the Opinion of Counsel and other
documents delivered pursuant to Sections 201 and 301 and this Section, as
applicable, at or prior to the time of the first authentication of Securities of
such series, unless and until it has received written notification that such
opinion or other documents have been superseded or revoked.  In connection with
the authentication and delivery of Securities of a series subject to a Periodic
Offering, the Trustee shall be entitled to assume that the Company's
instructions to authenticate and deliver such Securities do not violate any
rules, regulations or orders of any governmental agency or commission having
jurisdiction over the Company.

     Notwithstanding the provisions of Section 301 and of the preceding three
paragraphs, if all Securities of a series are subject to a Periodic Offering, it
shall not be necessary to deliver the Officers' Certificate otherwise required
pursuant to Section 301 at or prior to the time of authentication of each
Security of such series if such Officers' Certificate is delivered at or prior
to the authentication upon original issuance of the first Security of such
series to be issued.

                                       20
<PAGE>
 
     Each Registered Security shall be dated the date of its authentication;
and, unless otherwise specified as contemplated by Section 301, each Bearer
Security (including a Bearer Security represented by a temporary global
Security) shall be dated as of the date of original issuance of the first
Security of such series to be issued.

     The Trustee may appoint an authenticating agent acceptable to the Company
to authenticate Securities.  Unless otherwise provided in the appointment, an
authenticating agent may authenticate Securities whenever the Trustee may do so.
Each reference in this Indenture to authentication by the Trustee includes
authentication by such agent.

     No Security or coupon appertaining thereto shall be entitled to any benefit
under this Indenture or be valid or obligatory for any purpose, unless there
appears on such Security a certificate of authentication substantially in the
form provided for herein, executed by the Trustee by the manual signature of one
of its authorized signatories, and such certificate upon any Security shall be
conclusive evidence, and the only evidence, that such Security has been duly
authenticated and delivered hereunder. Notwithstanding the foregoing, if any
Security shall have been duly authenticated and delivered hereunder but never
issued and sold by the Company, and the Company shall deliver such Security to
the Trustee for cancellation as provided in Section 309, together with a written
statement (which need not comply with Section 102 and need not be accompanied by
an Opinion of Counsel) stating that such Security has never been issued and sold
by the Company, for all purposes of this Indenture such Security shall be deemed
never to have been authenticated and delivered hereunder and shall never be
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 a Company Order the Trustee shall authenticate and
deliver, temporary Securities that are printed, lithographed, typewritten,
photocopied or otherwise produced, in any authorized denomination, substantially
of the tenor of the definitive Securities in lieu of which they are issued, in
registered form or, if authorized, in bearer form, with one or more coupons or
without coupons, 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.  Such temporary Securities may
be in global form.

     Except in the case of Securities represented by a temporary global Security
(which shall be exchanged in accordance with the provisions of the three
succeeding paragraphs), if temporary Securities for some or all of the
Securities of any series are issued, the Company will cause definitive
Securities representing such Securities to be prepared without unreasonable
delay.  After the preparation of such definitive Securities, the temporary
Securities shall be exchangeable for such definitive Securities of like tenor
upon surrender of such temporary Securities at any office or agency of the
Company designated pursuant to Section 1002 in a Place of Payment for such
series for the purpose of exchanges of Securities of such series, without charge
to the Holder.  Upon surrender for cancellation of any one or more temporary
Securities of any series (accompanied by any unmatured coupons appertaining
thereto), the Company shall execute, and the Trustee shall authenticate and
deliver in exchange therefor, a like principal amount of definitive Securities
of the same series and of like tenor of authorized denominations; provided,
however, that no definitive Bearer Security shall be delivered in exchange for a
temporary 

                                       21
<PAGE>
 
Registered Security. Until so exchanged, the temporary Securities shall in all
respects be entitled to the same benefits under this Indenture as definitive
Securities.

     Unless otherwise specified as contemplated by Section 301, if Bearer
Securities of any series are represented by a Security in temporary global form,
any such temporary global Security shall be delivered to the Depositary for the
benefit of Euro-clear or Cedel S.A., for credit to the respective accounts of
the beneficial owners of such Securities (or to such other accounts as they may
direct).

     Without unnecessary delay, but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary global
Security (the "Exchange Date"), the Company shall deliver to the Trustee
definitive Securities of the same series, in aggregate principal amount equal to
the principal amount of such temporary global Security, executed by the Company.
On or after the Exchange Date, such temporary global Security shall be
surrendered by the Depositary to the Trustee, as the Company's agent for such
purpose, to be exchanged, in whole or from time to time in part, for definitive
Securities of the same series and of like tenor without charge, and the Trustee
shall authenticate and deliver, in exchange for each portion of such temporary
global Security, an equal aggregate principal amount of definitive Securities of
the same series of authorized denominations and of like tenor as the portion of
such temporary global Security to be exchanged. The definitive Securities to be
delivered in exchange for any such temporary global Security shall be in
definitive bearer form or registered form, or shall be represented by a
definitive global Security, or any combination thereof, as specified as
contemplated by Section 301, and, if any combination thereof is so specified, as
requested by the beneficial owner thereof.

     Unless otherwise specified in any such temporary global Security, the
interest of a beneficial owner of Securities of a series represented by such
temporary global Security shall be exchanged for definitive Securities of the
same series and of like tenor following the Exchange Date, when the account
holder instructs Euro-clear or Cedel S.A., as the case may be, to request such
exchange on his behalf and delivers to Euro-clear or Cedel S.A., as the case may
be, any certificate specified as contemplated by Section 301.  Unless otherwise
specified in such temporary global Security, any such exchange shall be made
free of charge to the beneficial owners of such temporary global Security,
except that a Person receiving definitive Securities must bear the cost of
insurance, postage, transportation and the like, in the event that such Person
does not take delivery of such definitive Securities in person at the offices of
Euro-clear or Cedel S.A.

     Until exchanged in full as hereinabove provided, the temporary Securities
of any series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of the same series and of like tenor
authenticated and delivered hereunder, except that, unless otherwise specified
as contemplated by Section 301, interest payable on a temporary global Security
representing a series of Bearer Securities on an Interest Payment Date for
Securities of such series occurring prior to the applicable Exchange Date shall
be payable to Euro-clear and Cedel S.A. on such Interest Payment Date, upon
delivery by Euro-clear and Cedel S.A. to the Trustee of any certificate
specified as contemplated by Section 301, for credit, without further interest
on or after such Interest Payment Date, to the respective accounts of the
Persons who are the beneficial owners of such temporary global Security on such
Interest Payment Date and who have each delivered to Euro-clear or Cedel S.A.,
as the case may be, any certificate specified as contemplated by Section 301.

Section 305.  Registration, Registration of Transfer and Exchange.

     (1)  The Company shall cause to be kept, at one of its offices or agencies
maintained pursuant to Section 1002, a register for the Securities accessible to
the Trustee (the register maintained in such office or agency designated
pursuant to Section 1002 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.

     (2)  Upon surrender for registration of transfer of any Security at an
office or agency of the Company designated pursuant to Section 1002 for such
purpose in a Place of Payment, the Company shall execute, and the Trustee or a
duly appointed co-authenticating agent shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Registered
Securities of the same series and of any authorized denominations, of a like
aggregate principal amount and tenor.

     (3)  Notwithstanding any other provisions (other than the provisions set
forth in the seventh and eighth paragraphs) of this Section, a Security in
global form representing all or a portion of the Securities of a series may not
be transferred, except as a whole by the Depositary for such series to a nominee
of such Depositary, or by a nominee of such Depositary to such Depositary or
another nominee of such Depositary, or by such Depositary or any such nominee to
a successor Depositary for such series or a nominee of such successor
Depositary.

     (4)  At the option of the Holder, Registered Securities of any series may
be exchanged for other Registered Securities of the same series of any
authorized denominations and of a like aggregate principal amount, terms and
tenor, upon surrender of the Securities to be exchanged at any 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. Bearer Securities
may not be issued in exchange for Registered Securities.

     (5)  At the option of the Holder, Bearer Securities of any series may be
exchanged for Registered Securities of the same series of any authorized
denominations and of a like aggregate principal amount, terms and tenor, upon
surrender of the Bearer Securities to be exchanged at any such office or agency,
with all unmatured coupons and all matured coupons in default thereto
appertaining.  If the Holder of a Bearer Security is unable to produce any such
unmatured coupon or coupons or matured coupon or coupons in default, such
exchange may be effected if the Bearer Securities are accompanied by payment, in
funds acceptable to the Company and the Trustee, in an amount equal to the face
amount of such missing coupon or coupons, or the surrender of such missing
coupon or coupons may be waived by the Company and the Trustee if there is
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless.  If thereafter the Holder of such Security
shall surrender to any Paying Agent any such missing coupon in respect of which
such a payment shall have been made, such Holder shall be entitled to receive
the amount of such payment; provided, however, that, except as otherwise
provided in Section 1002, interest represented by coupons shall be payable only
upon presentation and surrender of those coupons at an office or agency located
outside the United States. Notwithstanding the foregoing, in case a Bearer
Security of any series is surrendered at any such office or agency in exchange
for a Registered Security of the same series and terms and like tenor after the
close 

                                       23
<PAGE>
 
of business at such office or agency on (i) any Regular Record Date and before
the opening of business at such office or agency on the relevant Interest
Payment Date, or (ii) any Special Record Date and before the opening of business
at such office or agency on the related proposed date for payment of Defaulted
Interest, such Bearer Security shall be surrendered without the coupon relating
to such Interest Payment Date or proposed date for payment, as the case may be,
and interest or Defaulted Interest, as the case may be, will not be payable on
such Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security,
but will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture.

     (6)  Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee or a duly appointed authenticating agent shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

     (7)  If at any time the Depositary for the Securities of a series notifies
the Company that it is unwilling or unable to continue as Depositary for the
Securities of such series, or if such Depositary shall cease to be eligible to
act as such in respect of the Securities of such series, the Company shall
appoint a successor Depositary with respect to the Securities of such series.
If a successor Depositary for the Securities of such series is not appointed by
the Company within 90 days after the Company receives such notice, 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 form, in an
aggregate principal amount equal to the principal amount of the Security or
Securities in global form representing such series, in exchange for such
Security or Securities in global form in accordance with the instructions, if
any, of the Depositary.

     (8)  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 such global Security or Securities.  In such
event, or if an Event of Default with respect to the Securities of such series
shall have occurred and shall be continuing, 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 form, and in an aggregate principal amount equal to
the principal amount of the Security or Securities in global form representing
such series, in exchange for such Security or Securities in global form in
accordance with the instructions, if any, of the Depositary.

     (9)  Notwithstanding the foregoing, except as otherwise specified in the
preceding two paragraphs or as contemplated by Section 301, any definitive
global Security shall be exchangeable only as provided in this paragraph.  If
the beneficial owners of interests in a definitive global Security are entitled
to exchange such interests for definitive Securities of such series and of like
principal amount and tenor but of another authorized form and denomination, as
specified as contemplated by Section 301, then, without unnecessary delay, but
in any event not later than the earliest date on which such interests may be so
exchanged, the Company shall deliver to the Trustee definitive Securities, in
aggregate principal amount equal to the principal amount of such definitive
global Security, executed by the Company.  On or after the earliest date on
which such interests may be so exchanged, such definitive global Security shall
be surrendered by the Depositary with respect thereto to the Trustee, as the
Company's agent for such purpose, to be exchanged, in whole or from time to time
in part, for definitive Securities without charge, and the Trustee shall
authenticate and deliver, in exchange for each portion 

                                       24
<PAGE>
 
of such definitive global Security, an equal aggregate principal amount of
definitive Securities of the same series of authorized denominations and of like
tenor as the portion of such definitive global Security to be exchanged, which,
unless the Securities of the series are not issuable both as Bearer Securities
and as Registered Securities, as specified as contemplated by Section 301, shall
be in the form of Bearer Securities or Registered Securities, or any combination
thereof, as shall be specified by the beneficial owner thereof; provided,
however, that notwithstanding the last paragraph of this Section 305, no such
exchanges may occur during a period beginning at the opening of business 15 days
before any selection of Securities of that series to be redeemed and ending on
the relevant Redemption Date; and provided, further, that in connection with its
original issuance, no Bearer Security or coupon delivered in exchange for a
portion of a definitive global Security shall be mailed or otherwise delivered
to any Person that is not a Non-United States Holder or to any location in the
United States. If a Registered Security is issued in exchange for any portion of
a definitive global Security after the close of business at the office or agency
where such exchange occurs on (i) any Regular Record Date and before the opening
of business at such office or agency on the relevant Interest Payment Date, or
(ii) any Special Record Date and the opening of business at such office or
agency on the related proposed date for payment of Defaulted Interest, interest
or Defaulted Interest, as the case may be, will not be payable on such Interest
Payment Date or proposed date for payment, as the case may be, in respect of
such Registered Security, but will be payable on such Interest Payment Date or
proposed date for payment, as the case may be, only to the Person to whom
interest in respect of such portion of such definitive global Security is
payable in accordance with the provisions of this Indenture.

     (10)  Upon the exchange of a Security in global form for Securities in
definitive form, such Security in global form shall be cancelled by the Trustee.
All cancelled Securities and coupons held by the Trustee shall be disposed of by
the Trustee in accordance with its customary practice and a certificate of such
disposition delivered to the Company, unless the Company directs that such
cancelled Securities be returned to it. Registered Securities issued in exchange
for a Security in global form pursuant to this Section 305 shall be registered
in such names and in such authorized denominations as the Depositary for such
Security in global form, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee.  The Trustee shall
deliver such Registered Securities to the persons in whose names such Securities
are so registered.

     (11)  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.

     (12)  Every Registered 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.

     (13)  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, other
than exchanges upon the Company's repurchase or redemption of any Securities in
part at the option of the Holders thereof not 

                                       25
<PAGE>
 
involving any transfer, and other than exchanges of global Securities (or
portions thereof) for Securities in definitive form in accordance with Section
305.

     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 any selection of Securities of that series to be
redeemed and ending (except as otherwise provided in the first proviso in the
ninth paragraph of this Section 305) at the close of business on (A) if
Securities of the series are issuable only as Registered Securities, the day of
the mailing of the relevant notice of redemption and (B) if Securities of the
series are issuable as Bearer Securities, the day of the first publication of
the relevant notice of redemption or, if Securities of the series are also
issuable as Registered Securities and there is no publication, the mailing of
the relevant notice of redemption, or (ii) to register the transfer of or
exchange any Registered Security so selected for redemption, in whole or in
part, except the unredeemed portion of any Registered Security being redeemed in
part, or (iii) to exchange any Bearer Security so selected for redemption,
except that such a Bearer Security may be exchanged for a Registered Security of
that series and like tenor, terms and principal amount, provided that such
Registered Security shall be simultaneously surrendered for redemption.

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

     If any mutilated Security or a Security with a mutilated coupon
appertaining thereto 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 of like tenor and principal amount and bearing a
number not contemporaneously outstanding, with coupons corresponding to the
coupons, if any, appertaining to the surrendered Security.

     If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security or coupon
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice to
the Company or the Trustee that such Security or coupon has been acquired by a
bona fide purchaser, the Company shall execute, and upon its request the Trustee
shall authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security or in exchange for the Security to which a destroyed, lost or stolen
coupon appertains (with all appurtenant coupons not destroyed, lost or stolen),
a new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding, with coupons corresponding
to the coupons, if any, appertaining to such destroyed, lost or stolen Security
or to the Security to which such destroyed, lost or stolen coupon appertains.

     In case any such mutilated, destroyed, lost or stolen Security or coupon
has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, pay such Security or coupon; provided,
however, that principal of and any interest on Bearer Securities shall, except
as otherwise provided in Section 1002, be payable only at an office or agency
located outside the United States and, unless otherwise specified as
contemplated by Section 301, any interest on Bearer Securities shall be payable
only upon presentation and surrender of the coupons appertaining thereto.

     Upon the issuance of any new Security under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in 

                                       26
<PAGE>
 
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 or in exchange for a Security to which a
destroyed, lost or stolen coupon appertains, shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security and its coupons, if any, or the destroyed, lost or
stolen coupon shall be at any time enforceable by anyone, and any such new
Security and coupons, if any, shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities of that
issue and their coupons, if any, 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 or coupons.

Section 307.  Payment of Interest; Interest Rights Preserved.

     Unless otherwise provided as contemplated by Section 301 with respect to
any series of Securities, interest on any Registered Security which is payable,
and is punctually paid or duly provided for, on any Interest Payment Date shall
be paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest. In case a Bearer Security of any series is surrendered in
exchange for a Registered Security of such series after the close of business
(at an office or agency in a Place of Payment for such series) on any Regular
Record Date and before the opening of business (at such office or agency) on the
next succeeding Interest Payment Date, such Bearer Security shall be surrendered
without the coupon relating to such Interest Payment Date, and interest will not
be payable on such Interest Payment Date in respect of the Registered Security
issued in exchange for such Bearer Security, but will be payable only to the
Holder of such coupon when due in accordance with the provisions of this
Indenture.

     Any interest on any Registered 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 Registered Security 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 

                                       27
<PAGE>
 
     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
     Registered Securities, 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 (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
     Registered Securities in any other lawful manner not inconsistent with the
     requirements of any securities exchange on which such Registered Securities
     may be listed, and upon such notice as may be required by such exchange,
     if, after notice given by the Company to the Trustee of the proposed
     payment pursuant to this Clause, such manner of payment shall be deemed
     practicable by the Trustee.

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

Section 308.  Persons Deemed Owners.

     Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered as the
owner of such Registered Security for the purpose of receiving payment of
principal of and (except as otherwise specified as contemplated by Section 301
and subject to Section 305 and Section 307) interest on such Registered Security
and for all other purposes whatsoever, whether or not such Registered Security
be overdue, and neither the Company, the Trustee nor any agent of the Company or
the Trustee shall be affected by notice to the contrary.

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

     None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to, or payments made on account of, beneficial ownership
interests of a Security in global form or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

Section 309.  Cancellation.

     All Securities and coupons surrendered for payment, redemption,
registration of transfer or exchange or for credit against any sinking fund
payment shall, if surrendered to any Person other than the Trustee, be delivered
to the Trustee.  All Registered Securities and matured coupons so delivered
shall be promptly cancelled by the Trustee.  All Bearer Securities and unmatured
coupons so delivered shall be held by the Trustee and, upon instruction by a
Company Order, shall be cancelled or held for reissuance.  Bearer Securities and
unmatured coupons held for reissuance may be reissued only in replacement of
mutilated, lost, stolen or destroyed Bearer Securities of the same series and
like tenor and terms or the related coupons pursuant to Section 306.  All Bearer
Securities and unmatured coupons held by the Trustee pending such cancellation
or reissuance shall be deemed to be delivered for cancellation for all purposes
of this Indenture and the Securities.  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
(including Securities received by the Company in exchange or payment for other
securities of the Company), and may deliver to the Trustee (or to any other
Person for delivery to the Trustee) for cancellation any Securities previously
authenticated hereunder which the Company has not issued and sold, 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 Securities
cancelled as provided in this Section, except as expressly permitted in the form
of Securities for any particular series or as permitted pursuant to the terms of
this Indenture.  All cancelled Securities and coupons held by the Trustee may be
disposed of and certification of their disposition delivered to the Company,
unless by a Company Order the Company shall direct that such Securities be
returned to it.  Any cancelled Securities not disposed of shall be returned to
the Company.

Section 310.  Computation of Interest.

     Except as otherwise specified as contemplated by Section 301 for Securities
of any series, (i) interest on any Securities which bear interest at a fixed
rate shall be computed on the basis of a 360-day year of twelve 30-day months
and (ii) interest on any Securities which bear interest at a variable rate shall
be computed on the basis of the actual number of days in an interest period
divided by 360.

Company to pay additional amounts in respect of any such Securities as

Company shall be deemed to have paid and discharged its entire indebtedness on
all the Outstanding Securities or all Outstanding Securities of such series, as
the case may be, and the Trustee, at the expense of the Company, shall execute
proper instruments acknowledging satisfaction and discharge of the Company's
obligations under this Indenture, when

          (ii) below, are to be called for redemption, on the relevant
          Redemption Date, as the case may be, all principal of and interest on
          all Outstanding Securities or all Outstanding Securities of such
          series, as the case may be.  Such irrevocable trust agreement shall
          instruct the Trustee (i) to apply such money or the proceeds of said
          U.S. Government Obligations to the payment of said principal of and
          interest on the Securities or Securities of such series, as the case
          may be; and (ii) if the Securities or Securities of such series, as
          the case may be, are to be repaid at a Redemption Date and the Company
          has not given 

                                       30
<PAGE>
 
          notice of redemption pursuant to Section 1104 (including where such
          Securities are not yet redeemable at the date of deposit) to give
          notice of redemption on such Redemption Date pursuant to Section
          1104;

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

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

     Notwithstanding any such satisfaction and discharge, the Company shall not
be discharged from any payment obligations in respect of the Securities or the
Securities of such series, as the case may be, which are deemed not to be
Outstanding under Clause (iii) of the definition of "Outstanding" if such
obligations continue to be valid obligations of the Company under applicable
law.

Section 402.  Application of Trust Money.

     All money and U.S. Government Obligations (or any other obligations
specified as contemplated by Section 301 with respect to any series of
Securities, the principal of or any interest on which is payable other than in
the currency of the United States of America) deposited with the Trustee
pursuant to the trust agreement referred to in Section 401 shall be held in
trust and applied by it, in accordance with the provisions of the Securities of
the series with respect to which such deposit is made, this Indenture and such
trust agreement, to the payment, either directly or through any Paying Agent
(other than the Company) as the Trustee may determine, of the principal and
interest amounts due at the Stated Maturity or the Redemption Date, as the case
may be, with respect to the Securities of such series to the Persons entitled
thereto.

     All money and U.S. Government Obligations (or any other obligations
specified as contemplated by Section 301 with respect to any series of
Securities, the principal of or any interest on which is payable other than in
the currency of the United States of America) so deposited which remain
unclaimed for two years after payment to such Persons has become due and payable
shall be turned over to the Company in accordance with the provisions of Section
1003.

Section 501.  Events of Default.

     "Event of Default," wherever used herein, means, with respect to each
series of the Securities individually, 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):

                                       31
<PAGE>
 
          (1)  default in the payment of any installment of interest upon any
     Security of such series when it becomes due and payable, and continuance of
     such default for a period of 30 days; or

          (2)  default in the payment of the principal of any Security of such
     series at its Maturity; or

          (3)  default in the performance, or breach, of any covenant or

     of 60 days after there has been given, by registered or certified mail, to
     the Company by the Trustee or to the Company and the Trustee by the Holders
     of at least 25% in principal amount of the Outstanding Securities of such
     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

          (4)  a default under any bond, debenture, note or other evidence of
     indebtedness for money borrowed by the Company or under any mortgage,
     indenture, guaranty or instrument under which there may be issued or by
     which there may be secured or evidenced any indebtedness for money borrowed
     by the Company, whether such indebtedness now exists or shall hereafter be
     created, which default shall have resulted in such indebtedness becoming or
     being declared due and payable prior to the date on which it would
     otherwise have become due and payable, without such indebtedness having
     been discharged or such acceleration having been rescinded or annulled
     within a period of 20 days after there shall have 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 such series a written notice specifying such
     default and requiring the Company to cause such indebtedness to be
     discharged or such acceleration to be rescinded or annulled and stating
     that such notice is a "Notice of Default" hereunder; provided, that no
     Event of Default under this subsection (4) shall be deemed to exist as a
     result of the acceleration of any such indebtedness if the principal of and
     interest on such indebtedness, when added to the principal of and interest
     on all other such indebtedness which has been accelerated as aforesaid
     (excluding any such indebtedness which has been discharged or as to which
     the acceleration has been duly rescinded or annulled), shall not exceed
     $50,000,000; or

          (5)  the entry of a decree or order by a court having jurisdiction in
     the premises 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 Federal bankruptcy law
     or any other applicable Federal or State law, or appointing a 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 unstayed and in effect for a period of 60 consecutive days;
     or

                                       32
<PAGE>
 
          (6)  the institution by the Company of proceedings to be adjudicated a
     bankrupt or insolvent, or the consent by it to the institution of
     bankruptcy or insolvency proceedings against it, or the filing by it of a
     petition or answer or consent seeking reorganization or relief under
     Federal bankruptcy law or any other applicable Federal or state law, or the
     consent by it to the filing of such petition or to the appointment of a
     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

          (7)  any other event designated as an "Event of Default" 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 and 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 any of the
Securities of that series are Discount Securities, such portion of the principal
amount of such Securities as may be specified in the terms thereof) of and
accrued interest, if any, on 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 (or portion
thereof) and accrued interest, if any, 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 installments of interest on all Securities of
          such series;

               (B)  the principal of any Securities of such 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 installments of interest at the rate or rates
          prescribed therefor in such Securities or, if no such rate or rates is
          prescribed therefor in such Securities, at the rate of interest borne
          by such Securities; and

                                       33
<PAGE>
 
               (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 any other amount due the Trustee
          under Section 607;

     and

          (2)  all Events of Default with respect to Securities of such series,
     other than the non-payment of the principal of and interest on Securities
     of such 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 when such interest becomes due and payable and such default
     continues for a period of 30 days, or

          (2)  default is made in the payment of the principal of 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 interest, with interest upon the overdue principal
and, to the extent that payment of such interest shall be legally enforceable,
upon overdue installments of interest from the date such interest was due, at
the rate or rates prescribed therefor in such Securities or, if no such rate or
rates is prescribed therefor in such Securities, at the rate of interest borne
by 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 and any other amount due the Trustee under Section 607.

     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
     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 any other amount due the Trustee under Section 607)
     and of the Holders of Securities and coupons 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 receiver, assignee, trustee, liquidator, sequestrator or other similar
official in any such judicial proceeding is hereby authorized by each Holder of
Securities and coupons to make such payments to the Trustee and, in the event
that the Trustee shall consent to the making of such payments directly to the
Holders of Securities and coupons, 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 of a Security
or coupon any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or coupons or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder of a
Security or coupon in any such proceeding.

Section 505.  Trustee May Enforce Claims Without Possession of Securities or
Coupons.

     All rights of action and claims under this Indenture or the Securities or
coupons may be prosecuted and enforced by the Trustee without the possession of
any of the Securities or coupons or the production thereof in any proceeding
relating thereto, and any such proceeding instituted by the Trustee shall be
brought in its own name as trustee of an express trust, and any recovery 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 and coupons in respect
of which such judgment has been recovered.

Section 506.  Application of Money Collected.

                                       35
<PAGE>
 
     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 interest,
upon presentation of the Securities or coupons, or both, as the case may be, and
the notation thereon of the payment if only partially paid and upon surrender
thereof if fully paid:

          First: To the payment of all amounts due the Trustee under Section
     607;

          Second: To the payment of the amounts then due and unpaid for
     principal of and interest on the Securities and interest evidenced by
     coupons 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 and coupons for principal
     and interest, respectively; and

          Third: To the payment of the remainder, if any, to the Company.

Section 507.  Limitation on Suits.

     No Holder of any Security of any series or any related coupons 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 reasonable
     indemnity against the costs, expenses and liabilities to be incurred in
     compliance with such request;

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

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

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

Section 508.   Unconditional Right of Holders to Receive Principal and Interest.

                                       36
<PAGE>
 
     Notwithstanding any other provision in this Indenture, the Holder of any
Security or coupon shall have the right, which is absolute and unconditional, to
receive payment of the principal of and (subject to Section 307) interest on
such Security or payment of such coupon on the Stated Maturities or Maturities
expressed in such Security or coupon (or, in the case of redemption, on the
Redemption Date or, in the case of redemption or repurchase by the Company at
the option of the Holder, on the date fixed for such redemption or repurchase,
as the case may be) 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 of a Security or coupon has instituted any
proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Trustee or to such Holder, then and in every such
case, subject to any determination in such proceeding, the Company, the Trustee
and the Holders of Securities and coupons 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 or coupons in the last paragraph
of Section 306, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders of Securities or coupons 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 Security or
coupon to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of
Default or an acquiescence therein.  Every right and remedy given by this
Article or by law to the Trustee or to the Holders of Securities or coupons may
be exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders of Securities or coupons, as the case may be.

Section 512.  Control by Holders of Securities.

     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,

                                       37
<PAGE>
 
          (2)  the Trustee shall not have determined that the action so directed
     would be unjustly prejudicial to the Holders not taking part in such
     direction, and

          (3)  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, by notice to the Trustee (and without
notice to any other Holder), may on behalf of the Holders of all the Securities
of such series and any related coupons waive any past default hereunder and its
consequences, except a default

          (1)  in the payment of the principal of 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 and
expenses, 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
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 of any Security or coupon
for the enforcement of the payment of the principal of or interest on any
Security or the payment of any coupon on or after the Stated Maturity or
Maturities expressed in such Security or coupon (or, in the case of redemption,
on or after the Redemption Date or, in the case of redemption or repurchase by
the Company at the option of the Holder, on the date fixed for such redemption
or repurchase, as the case may be).

Section 515.  Waiver of Usury, Stay or Extension Laws.

     The Company covenants (to the extent that it may lawfully do so) that it
will not at any time voluntarily (and that it will resist any effort to make it
do so involuntarily) insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any usury, stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this 

                                       38
<PAGE>
 
Indenture or the Securities; 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.

                                  ARTICLE SIX

                                  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 with
respect to the Securities of any series, the Trustee shall exercise such of the
rights and powers vested in it by this Indenture with respect to the Securities
of such series, and use the same degree of care and skill in their exercise, as
a prudent person 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 willful 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; and

          (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 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.

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.

     (e)  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

however, that, except in the case of a default in the payment of the principal
of or interest on any Security of such series or in the payment of any sinking
fund installment with respect to any Security of such series, the Trustee shall

directors, the executive committee or a trust committee of directors or
Responsible Officers of the Trustee in good faith determine that the withholding

     negligence on the part of any agent or attorney appointed with due care by
     it hereunder; and

          (h) the Trustee shall not be liable for any action taken or omitted by
     it in good faith and believed by it to be authorized or within the

     The Trustee, 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

<PAGE>
 
     The Company agrees

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

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

          (3)  to indemnify the Trustee for, and to hold it harmless against,

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, and subject to supervision or examination by Federal or
State authority.  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.  The Trustee shall
comply with Trust Indenture Act Sections 310(a)(5) and 310(b).

Section 609.  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 under Section 610.

     (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 an
instrument of acceptance by a successor Trustee shall not have been delivered to
the Trustee within 30 days after the giving of such notice of resignation, the

                                       42
<PAGE>
 
resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such issue.

     (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 the last sentence of
     Section 608 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
     such shorter period as the Securities have been outstanding), or

          (2)  the Trustee shall cease to be eligible under Section 608 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 (or
such shorter period as the Securities have been outstanding) 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).  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, become the successor Trustee with respect to the Securities
of such series and 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 hereinafter provided, any Holder who has been a bona fide Holder of a
Security of such series for at least six months (or such shorter period as the
Securities have been outstanding) 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.

                                       43

     (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 in the manner
provided in Section 106.  Each notice shall include the name of the successor
Trustee and the address of its Corporate Trust Office.

Section 610.   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 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 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, subject nevertheless to its lien, if
any, provided for in Section 607.

     (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 as 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, subject, nevertheless, to its lien, if any,
provided for in Section 607.

     (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.

                                       44

     (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 611.   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 612.  Preferential Collection of Claims Against Company.

     The Trustee shall comply with Trust Indenture Act Section 311(a), excluding
any creditor relationship listed in Trust Indenture Act Section 311(b).  A
Trustee who has resigned or been removed shall be subject to Trust Indenture Act
Section 311(a) to the extent indicated therein.

     rights of any Holder.

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 the Securities of such series and any related coupons 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
     installment of principal or interest on, any such Security, or reduce the
     principal amount thereof or the rate of interest thereon or any premium
     payable thereon, or reduce the amount of principal of any such Discount
     Security that would be due and payable upon a declaration of acceleration
     of maturity thereof pursuant to Section 502, or change the Place of Payment
     where, or coin or currency in which, any principal of, or any installment
     of interest on, any such Security 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, in the case of Securities which are subject to
     repurchase or redemption by the Company at the option of the Holders, on or
     after the date fixed for such repurchase or redemption);

          (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) with respect to the
     Securities of such series provided for in this Indenture; or

          (3) modify any of the provisions of this Section, Section 513 or
     Section 1010, 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.

     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, liabilities 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
and of any coupons appertaining thereto shall be bound thereby.

Section 905.  Conformity with Trust Indenture Act.

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 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 any
interest on the Securities of that series in accordance with the terms of the
Securities, any coupons appertaining thereto and this Indenture.  An installment
of principal or interest on the Securities shall be considered paid on the date
it is due if the Trustee or a Paying Agent (other than the Company or an
Affiliate of the Company) holds on that date funds (in the currency or
currencies of payment with respect to such Securities) designated for and
sufficient to pay 

                                       50
<PAGE>
 
such installment. Unless otherwise specified as contemplated by Section 301 with
respect to any series of Securities, any interest due on Bearer Securities on or
before Maturity shall be payable only upon presentation and surrender of the
several coupons for such interest installments as are evidenced thereby as they
severally mature. At the Company's option, payment of principal or interest may
be made by check or by transfer to an account maintained by the payee (provided,
in the case of Registered Securities, the Trustee has received written payment
instructions at least fifteen days prior to any payment date) subject, in the
case of Bearer Securities, to the provisions of Section 1002.

Section 1002.  Maintenance of Office or Agency.

     If Securities of a series are issuable only as Registered Securities, the
Company will maintain in each Place of Payment for such series 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.  If
Securities of a series are issuable as Bearer Securities, the Company will
maintain (A) in the Borough of Manhattan, The City of New York, an office or
agency where any Registered Securities of that series may be presented or
surrendered for payment, where any Registered Securities of that series may be
surrendered for registration of transfer, where Securities of that series may be
surrendered for exchange, where notices and demands to or upon the Company in
respect of the Securities of that series and this Indenture may be served and
where Bearer Securities of that series and related coupons may be presented or
surrendered for payment in the circumstances described in the following
paragraph (and not otherwise); (B) subject to any laws or regulations applicable
thereto, in a Place of Payment for that series which is located outside the
United States, an office or agency where Securities of that series and related
coupons may be presented and surrendered for payment (including payment of any
additional amounts payable on Securities of that series pursuant to Section
1011); provided, however, that, if the Securities of that series are listed on
The London Stock Exchange, the Luxembourg Stock Exchange or any other stock
exchange located outside the United States and such stock exchange shall so
require, the Company will maintain a Paying Agent for the Securities of that
series in London, Luxembourg or any other required city located outside the
United States, as the case may be, so long as the Securities of that series are
listed on such exchange; and (C) subject to any laws or regulations applicable
thereto, in a Place of Payment for that series which is located outside the
United States, an office or agency where any Registered Securities of that
series may be surrendered for registration of transfer, where Securities of that
series may be surrendered for exchange and where notices and demands to or upon
the Company in respect of the Securities of that series and this Indenture may
be served.  The Company will give prompt written notice to the Trustee and the
Holders of the location, and any change in the location, of any such office or
agency.  If at any time the Company shall fail to maintain any such required
office or agency in respect of any series of Securities, or shall fail to
furnish the Trustee with the address thereof, such presentations and surrenders
of Securities of that series may be made, and notices and demands may be made or
served, at the Corporate Trust Office of the Trustee, except that Bearer
Securities of that series and the related coupons may be presented and
surrendered for payment (including payment of any additional amounts payable on
Bearer Securities of that series pursuant to Section 1011) at the place
specified for that purpose as contemplated by Section 301 or, if no such place
is specified, at the main office of the Trustee in London, and the Company
hereby appoints the same as its agent to receive such respective presentations,
surrenders, notices and demands.

                                       51
<PAGE>
 
     No payment of principal or interest on Bearer Securities shall be made at
any office or agency of the Company in the United States, by check mailed to any
address in the United States, by transfer to an account located in the United
States or upon presentation or surrender in the United States of a Bearer
Security or coupon for payment, even if the payment would be credited to an
account located outside the United States; provided, however, that, if the
Securities of a series are denominated and payable in Dollars, payment of
principal of and any interest on any such Bearer Security (including any
additional amounts payable on Securities of such series pursuant to Section
1011) shall be made at the office of the Company's Paying Agent in the Borough
of Manhattan, The City of New York, if (but only if) payment in Dollars of the
full amount of such principal, interest or additional amounts, as the case may
be, at all offices or agencies outside the United States maintained for the
purpose by the Company in accordance with this Indenture is illegal or
effectively precluded by exchange controls or other similar restrictions.

     The Company may also from time to time designate one or more other offices
or agencies where the Securities 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 accordance with the requirements set forth above 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.

     Unless otherwise specified pursuant to Section 301 with respect to the
Securities of any series, the Trustee shall be a Paying Agent and Transfer Agent
for the Securities of such series (until replaced or removed by the Company in
accordance with this Indenture), and the office or agency of the Company
maintained in the Borough of Manhattan, The City of New York in respect of the
Securities of such series for the purposes contemplated by this Section 1002
shall be the Corporate Trust Office of the Trustee located in the Borough of
Manhattan, The City of New York.

Section 1003.  Money for Security 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 the Securities, it will, on or before each due date of the
principal of 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 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
the Securities, it will, on or prior to each due date of the principal of or
interest on any Securities of that series, deposit with a Paying Agent a sum
sufficient to pay the principal or interest so becoming due, such sum to be held
in trust for the benefit of the Persons entitled to such principal 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.

     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:

                                       52
<PAGE>
 
          (1) hold all sums held by it for the payment of the principal of or
     interest on Securities of such series in trust for the benefit of the
     Persons entitled thereto until such sums shall be paid to such Persons or
     otherwise disposed of as herein provided;

          (2) give the Trustee notice of any default by the Company (or any
     other obligor upon the Securities of such series) in the making of any
     payment of principal or interest on the Securities of such 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 or interest on any
Security of any series and remaining unclaimed for two years after such
principal 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 or any coupon appertaining thereto 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 and direction of the Company cause to be published once, in an
Authorized Newspaper in each Place of Payment, 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.  (Intentionally Omitted).

Section 1006.  (Intentionally Omitted).

Section 1007.  Limitation on Liens.

                                       53
<PAGE>
 
     The Company will not, and will not permit any Consolidated Subsidiary to,
incur, create, assume, guarantee or otherwise become liable with respect to any
Secured Debt, unless (i) the Company secures or causes such Consolidated
Subsidiary to secure the Securities equally and ratably with (or prior to) such
Secured Debt or (ii) after giving effect thereto, the aggregate amount of all
Secured Debt, together with all Discounted Rental Value in respect of sale and
leaseback transactions involving Principal Domestic Properties (excluding sale
and leaseback transactions exempted from the prohibition of subsection (a) of
Section 1008 by subsection (b) of Section 1008), would not exceed 10% of
Consolidated Net Tangible Assets; provided, however, that for purposes of this
Section there shall be excluded from Secured Debt all Indebtedness secured by:

          (a)  Liens existing on the date of this Indenture;

          (b)  Liens existing on property of, or on any shares of stock or
     Indebtedness of, any corporation at the time such corporation becomes a
     Consolidated Subsidiary;

          (c)  Liens in favor of the Company or a Consolidated Subsidiary;

          (d)  Liens in favor of governmental bodies to secure progress, advance
     or other payments pursuant to any contract or provision of any statute;

          (e)  Liens existing on property, shares of stock or Indebtedness at
     the time of acquisition thereof (including acquisition through merger or
     consolidation) or Liens (i) to secure the payment of all or any part of the
     purchase price thereof or the cost of construction, installation,
     renovation, improvement or development thereon or thereof or (ii) to secure
     any Indebtedness incurred prior to, at the time of, or within 360 days
     after the later of the acquisition, the completion of such construction,
     installation, renovation, improvement or development or the commencement of
     full operation of such property or within 360 days after the acquisition of
     such shares or Indebtedness for the purpose of financing all or any part of
     the purchase price or cost thereof; and

          (f)  any extension, renewal or refunding of any Liens referred to in
     the foregoing clauses (a) through (e), inclusive, provided, however, that
     (i) such extension, renewal or refunding Lien shall be limited to all or
     part of the same property, shares of stock or Indebtedness that secured the
     Lien extended, renewed or refunded (plus improvements on or replacements of
     such property) and (ii) such Secured Debt at such time is not increased.

Section 1008.  Limitation on Sale and Leaseback Transactions.

     (a)  The Company will not, and will not permit any Consolidated Subsidiary
to, sell or transfer any Principal Domestic Property, with the Company or any
Consolidated Subsidiary taking back a lease of such Principal Domestic Property,
unless: (i) such Principal Domestic Property is sold within 360 days from the
date of acquisition of such Principal Domestic Property or the date of the
completion of construction or commencement of full operations on such Principal
Domestic Property, whichever is later; or (ii) the Company or such Consolidated
Subsidiary could subject such Principal Domestic Property to a Lien pursuant to
Section 1007 in an amount equal to the Discounted Rental Value with 

                                       54
<PAGE>
 
respect to such sale and leaseback transaction without equally and ratably
securing the Securities; or (iii) the Company or such Consolidated Subsidiary,
within 120 days after such sale, applies or causes to be applied to the
retirement of its Funded Debt an amount not less than the greater of (A) the net
proceeds of the sale of such Principal Domestic Property or (B) the fair value
(as determined in any manner approved by the Board of Directors) of such
Principal Domestic Property; provided, however, that the amount to be applied to
the retirement of Funded Debt of the Company or such Consolidated Subsidiary
shall be reduced by the principal amount of Funded Debt of the Company or such
Consolidated Subsidiary voluntarily retired by the Company or such Consolidated
Subsidiary within 120 days after such sale.

     (b)  The provisions of this Section shall not prevent (i) a sale and
leaseback transaction between the Company and a Consolidated Subsidiary or
between Consolidated Subsidiaries or (ii) a sale or transfer of any Principal
Domestic Property with a lease for a period, including renewals, of not more
than 36 months.

Section 1009.  Statement by Officer as to Compliance; Notice of Certain Events.

     The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year of the Company ending after the date hereof, a brief
certificate, signed by the principal executive officer, the principal financial
officer or the principal accounting officer of the Company, as to the signer's
knowledge of the Company's compliance with all conditions and covenants under
this Indenture.  For purposes of this Section 1009, such compliance shall be
determined without regard to any period of grace or requirement of notice
provided under any of the provisions of this Indenture.  The Company's fiscal
year ends on December 31 of each year.  The Company will notify the Trustee in
the event that such fiscal year changes.  The Company will deliver to the
Trustee, within 20 days after the occurrence thereof, notice of each
acceleration which, with giving of notice by the Trustee or Holders and the
lapse of time, would be an Event of Default within the meaning of Section
501(4).

Section 1010.  Waiver of Certain Covenants.

     The Company may omit in any particular instance to comply with any covenant
or condition set forth in Section 1004, 1007, 1008, or 1011 with respect to the
Securities of any series, if before or after the time for such compliance the
Holders of at least a majority in principal amount of the Outstanding Securities
of such series shall, by Act of such Holders, either waive such compliance in
such instance or generally waive compliance with such covenant or condition, but
no such waiver shall extend to or affect such covenant or condition except to
the extent so expressly waived, and, until such waiver shall become effective,
the obligations of the Company and the duties of the Trustee in respect of any
such covenant or condition shall remain in full force and effect.

Section 1011.  Additional Amounts.

     If specified as contemplated by Section 301, the Securities of a series may
provide for the payment of additional amounts, and in such case, the Company
will pay to the Holder of any Security of such series or any coupon appertaining
thereto additional amounts as provided therein.  Whenever in this Indenture
there is mentioned, in any context, the payment of the principal of or any
interest on, or in respect of, any Security of any series or payment of any
related coupon, such mention shall be deemed 

                                       55
<PAGE>
 
to include mention of the payment of additional amounts provided for in this
Section to the extent that, in such context, additional amounts are, were or
would be payable in respect thereof pursuant to the provisions of this Section,
and express mention of the payment of additional amounts (if applicable) in any
provisions hereof shall not be construed as excluding additional amounts in
those provisions hereof where such express mention is not made.

     If the Securities of a series provide for the payment of additional
amounts, at least 10 days prior to the first Interest Payment Date with respect
to that series of Securities (or if the Securities of that series will not bear
interest prior to Maturity, the first day on which a payment of principal is
made), and at least 10 days prior to each date of payment of principal and any
interest if there has been any change with respect to the matters set forth in
the below-mentioned Officers' Certificate, the Company will furnish the Trustee
and the Company's Paying Agent or Paying Agents, if other than the Trustee, with
an Officers' Certificate instructing the Trustee and such Paying Agent or Paying
Agents whether such payment of principal of and any interest on the Securities
of that series shall be made to Holders of Securities of that series or any
related coupons who are Non-United States Holders without withholding for or on
account of any tax, assessment or other governmental charge described in the
Securities of that series.  If any such withholding shall be required, then such
Officers' Certificate shall specify by country the amount, if any, required to
be withheld on such payments to such Holders of Securities or coupons, and the
Company will pay to the Trustee or such Paying Agent the additional amounts
required by the Securities of such series and this Section.  The Company
covenants to indemnify the Trustee and any Paying Agent for, and to hold them
harmless against, any loss, liability or expense reasonably incurred, without
negligence or bad faith on their part, arising out of or in connection with
actions taken or omitted by any of them in reliance on any Officers' Certificate
furnished pursuant to this Section.

                            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.

     In the event that the Company elects to redeem Securities of any series,
the Company shall, at least 60 days prior to the Redemption Date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee of such Redemption Date, of the principal amount of the Securities
to be redeemed and of any other information necessary to identify the Securities
of such series to be redeemed.

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

     Unless otherwise specified as contemplated by Section 301 with respect to
any series of Securities, if less than all the Securities of any series with the
same issue date, interest rate, Stated 

                                       56
<PAGE>
 
Maturity and other terms are to be redeemed, the particular Securities to be
redeemed shall be selected not more than 60 days prior to the Redemption Date by
the Trustee, from the Outstanding Securities of such series not previously
called for redemption, by such method as the Trustee shall deem fair and
appropriate, which method 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 Registered
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.

     Unless otherwise specified as contemplated by Section 301 with respect to
any series of Securities, notice of redemption shall be given in the manner
provided in Section 106 to the Holders of Securities to be redeemed not less
than 30 nor more than 60 days prior to the Redemption Date.

     All notices of redemption shall identify the Securities to be redeemed
(including, if applicable, the CUSIP number thereof) and shall state:

          (1)  the Redemption Date;

          (2)  the Redemption Price;

          (3)  if fewer 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 (or portion thereof) to be redeemed,
     together with (if applicable) accrued and unpaid interest thereon and, if
     applicable, that interest thereon will cease to accrue on and after said
     date;

          (5)  the place or places where such Securities, together, in the case
     of Bearer Securities, with all coupons, if any, appertaining thereto
     maturing after the Redemption Date, 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.

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

                                       57
<PAGE>
 
     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, if accrued and unpaid
interest on the Securities (or portions thereof) to be redeemed is, pursuant to
the terms of this Indenture or such Securities, payable to the Persons entitled
to receive the Redemption Price thereof, 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 and the coupons for such
interest appertaining to any Bearer Securities so to be redeemed, except to the
extent provided below, shall be void.  Upon surrender of any such Security for
redemption in accordance with said notice, together with all coupons, if any,
appertaining thereto maturing after the Redemption Date, such Security shall be
paid by the Company at the Redemption Price, together with accrued interest to
the Redemption Date; provided, however, that installments of interest on Bearer
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable only at an office or agency located outside the United States (except as
otherwise provided in Section 1002) and, unless otherwise specified as
contemplated by Section 301, only upon presentation and surrender of coupons for
such interest; and provided, further, that, unless otherwise specified as
contemplated by Section 301, installments of interest on Registered Securities
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Regular Record Dates
according to their terms and the provisions of Sections 305 and 307.

     If any Bearer Security surrendered for redemption shall not be accompanied
by all appurtenant coupons maturing after the Redemption Date, such Security may
be paid after deducting from the Redemption Price an amount equal to the face
amount of all such missing coupons, or the surrender of such missing coupon or
coupons may be waived by the Company and the Trustee if there be furnished to
them such security or indemnity as they may require to save each of them and any
Paying Agent harmless.  If thereafter the Holder of such Security shall
surrender to the Trustee or any Paying Agent any such missing coupon in respect
of which a deduction shall have been made from the Redemption Price, such Holder
shall be entitled to receive the amount so deducted; provided, however, that
interest represented by coupons shall be payable only at an office or agency
located outside the United States (except as otherwise provided in Section 1002)
and, unless otherwise specified as contemplated by Section 301, only upon
presentation and surrender of those coupons.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal shall, until paid, bear interest from the
Redemption Date at the rate prescribed therefor in the Security or, if no such
rate is so prescribed, at the rate of interest borne by the Security.

Section 1107.  Securities Redeemed in Part.

     Any Registered 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 Registered Security or Securities of the same
series and of like 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.

                                 ARTICLE TWELVE

                                 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 with the
same issue date, interest rate, and Stated Maturity and other terms (other than
any previously called for redemption), together, in the case of any Bearer
Securities of such series with the same issue date, interest rate, Stated
Maturity and other terms, with all unmatured coupons appertaining thereto, and
(2) may apply as a credit Securities of a series with the same issue date,
interest rate, Stated Maturity and other terms 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 mandatory sinking fund payment with respect to the Securities of such series
with the same issue date, interest rate, Stated Maturity and other terms;
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 

                                       59
<PAGE>
 
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 (or such shorter period as shall be acceptable to the
Trustee) 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 30 days before each such sinking fund payment date, the Trustee shall
select the Securities to be redeemed upon such sinking fund payment date in the
manner specified in Section 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.

                                ARTICLE THIRTEEN

Securities of such series.

Section 1302.  Call, Notice and Place of Meetings.

     (a)  The Trustee may at any time call a meeting of Holders of Securities of
any series for any purpose specified in Section 1301, to be held at such time
and at such place in the Borough of Manhattan, The City of New York, or in
London, as the Trustee shall determine or, with the approval of the Company, at
any other place.  Notice of every meeting of Holders of Securities of any

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

requested the Trustee to call a meeting of the Holders of Securities of such
series for any purpose specified in Section 1301, by written request setting
forth in reasonable detail the action proposed to be taken at the meeting, and
the Trustee shall not have made the first publication of the notice of such
meeting within 21 days after receipt of such request or shall not thereafter
proceed to cause the meeting to be held as provided herein, then the Company or
the Holders of Securities of such series in the amount above specified, as the
case may be, may determine the time and the place in the Borough of Manhattan,
The City of New York, or in London, or in such other place 

                                       60
<PAGE>
 
as shall be determined and approved by the Company, for such meeting and may
call such meeting for such purposes by giving notice thereof as provided in
Subsection (a) of this Section.

Section 1303.  Persons Entitled to Vote at Meetings.

     To be entitled to vote at any meeting of Holders of Securities of any
series, a Person shall be (1) a Holder of one or more Outstanding Securities of
such series or (2) a Person appointed by an instrument in writing as proxy for a
Holder or Holders of one or more Outstanding Securities of such series by such
Holder or Holders.  The only Persons who shall be entitled to be present or to
speak at any meeting of Holders of Securities of any series shall be the Persons
entitled to vote at such meeting and their counsel, any representatives of the
Trustee and its counsel and any representatives of the Company and its counsel.

Section 1304.  Quorum; Action.

     The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for a meeting of
Holders of Securities of such series; provided, however, that if any action is
to be taken at such meeting with respect to a consent or waiver which this
Indenture expressly provides may be given by the Holders of a specified
percentage, which is less than a majority, in principal amount of the
Outstanding Securities of a series, the Persons entitled to vote such lesser
percentage in principal amount of the Outstanding Securities of such series
shall constitute a quorum. In the absence of a quorum within 30 minutes of the
time appointed for any such meeting, the meeting shall, if convened at the
request of Holders of Securities of such series, be dissolved.  In any other
case, the meeting may be adjourned for a period determined by the chairman of
the meeting prior to the adjournment of such meeting.  In the absence of a
quorum at any such adjourned meeting, such adjourned meeting may be further
adjourned for a period determined by the chairman of the meeting prior to the
adjournment of such adjourned meeting.  Notice of the reconvening of any
adjourned meeting shall be given as provided in Section 1302(a), except that
such notice need be given only once not less than five days prior to the date on
which the meeting is scheduled to be reconvened.  Notice of the reconvening of
an adjourned meeting shall state expressly the percentage, as provided above, of
the principal amount of the Outstanding Securities of such series which shall
constitute a quorum.

     Except as limited by the proviso to Section 902, any resolution presented
to a meeting or adjourned meeting duly reconvened at which a quorum is present,
as aforesaid, may be adopted by the affirmative vote of the Holders of a
majority in principal amount of the Outstanding Securities of that series;
provided, however, that, except as limited by the proviso to Section 902, any
resolution with respect to any request, demand, authorization, direction,
notice, consent, waiver or other action which this Indenture expressly provides
may be made, given or taken by the Holders of a specified percentage, which is
less than a majority, in principal amount of the Outstanding Securities of a
series may be adopted at a meeting or an adjourned meeting duly reconvened and
at which a quorum is present, as aforesaid, by the affirmative vote of the
Holders of such specified percentage in principal amount of the Outstanding
Securities of that series.

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

Section 1305.  Determination of Voting Rights; Conduct and Adjournment of
Meetings.

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

     (b)  The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of Securities as provided in Section 1302(b), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman.  A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

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

     (d)  Any meeting of Holders of Securities of any series duly called
pursuant to Section 1302 at which a quorum is present may be adjourned from time
to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

Section 1306.  Counting Votes and Recording Action of Meetings.

     The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed signatures of the Holders of Securities of such series or of their
representatives by proxy and the principal amounts and serial numbers of the
Outstanding Securities of such series held or represented by them.  The
permanent chairman of the meeting shall appoint two inspectors of votes, who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in duplicate of all votes cast at the meeting.  A record, at least in
duplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting, and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits, signed by one or more persons
having knowledge of the facts, setting forth a copy 

                                       62
<PAGE>
 
of the notice of the meeting and showing that said notice was given as provided
in Section 1302 and, if applicable, Section 1304. Each copy shall be signed and
verified by the affidavits of the permanent chairman and secretary of the
meeting and one such copy shall be delivered to the Company and another to the
Trustee, to be preserved by the Trustee, the latter to have attached thereto the
ballots voted at the meeting. Any record so signed and verified shall be
conclusive evidence of the matters therein stated.

          Re:  Occidental Petroleum Corporation
               Registration Statement on Form S-3
               ----------------------------------

Ladies and Gentlemen:

          I am an Associate General Counsel of Occidental Petroleum Corporation,
a Delaware corporation ("Occidental"), and am rendering this opinion in
connection with the preparation of the above-referenced Registration Statement
on Form S-3 (the "Registration Statement"), which is to be filed by Occidental
on May 5, 1998, with the Securities and Exchange Commission (the "Commission").
The Registration Statement relates to the registration under the Securities Act
of 1933, as amended (the "Securities Act"), of $800,000,000 aggregate public
offering price of senior unsecured debt securities (the "Debt Securities") of
Occidental. The Debt Securities are being registered for offering and sale from
time to time pursuant to Rule 415 under the Securities Act. The Debt Securities
are to be issued pursuant to the Indenture, dated as of April 1, 1998 (the
"Indenture"), between Occidental and The Bank of New York, a New York banking
corporation, as trustee (the "Trustee").

          This opinion is delivered in accordance with the requirements of Item
601(b) (5) of Regulation S-K under the Securities Act.

          In connection with this opinion, I have examined and am familiar with
originals or copies, certified or otherwise identified to my satisfaction, of
such 
<PAGE>
 
documents as I have deemed necessary or appropriate as a basis for the opinions
set forth herein, including (i) the Registration Statement (together with the
form of preliminary prospectus forming a part thereof), (ii) the Restated
Certificate of Incorporation and By-Laws of Occidental, in each case, as amended
to date, (iii) the Indenture, and (iv) copies of certain resolutions adopted by
the Board of Directors of Occidental relating to the execution of the Indenture,
the issuance of the Debt Securities, the filing of the Registration Statement
and any amendments or supplements thereto and related matters. In my
examination, I have assumed the legal capacity of natural persons, the
signatures (other than signatures executing documents on behalf of Occidental)
on all documents examined or caused to be examined by me are genuine, that all
documents submitted to me as originals are authentic, and that all documents
submitted to me as copies conform with the originals, which assumptions I have
not independently verified. As to any facts material to the opinions expressed
herein which I have not independently established or verified, I have relied
upon statements and representations of officers and other representatives of
Occidental and others.

          I am a member of the California and New York Bars and for purposes of
this opinion do not hold myself out as an expert on, nor do I express any
opinion as to, the laws of any jurisdiction other than the laws of the State of
California, the laws of the State of New York, the Federal laws of the United
States and the General Corporation Law of the State of Delaware.  The Debt
Securities may be issued from time to time on a delayed or continuous basis and
this opinion is limited to the laws, including the rules and regulations, as in
effect on the date hereof.

          Based upon and subject to the foregoing, I am of the opinion that when
(i) the Registration Statement becomes effective under the Securities Act; (ii)
the appropriate officers of Occidental have taken all necessary action pursuant
to Section 301 of the Indenture to fix and approve the terms of the Debt
Securities, including the establishment of the form or forms of certificates
representing the Debt Securities pursuant to Section 201 of the Indenture; (iii)
the Indenture shall have been qualified under the Trust Indenture Act of 1939,
as amended; and (iv) the Debt Securities are duly executed and authenticated in
accordance with the provisions of the Indenture and duly delivered to the
purchasers thereof upon payment of the agreed upon consideration therefor, the
Debt Securities will be validly issued and binding obligations of Occidental,
enforceable against Occidental in accordance with their terms, except as may be
subject to or limited by (i) bankruptcy, insolvency, reorganization, moratorium
or other similar laws now or hereafter in effect relating to creditors' rights
generally, (ii) general principles of equity (regardless of whether 
<PAGE>
 
enforcement is considered in a proceeding in equity or at law), (iii)
requirements that a claim with respect to any Debt Securities authenticated and
delivered under the Indenture denominated other than in United States dollars
(or a judgment denominated other than in United States dollars in respect of
such claim) be converted into United States dollars at a rate of exchange
prevailing on a date determined pursuant to applicable law, and (iv)
governmental authority to limit, delay or prohibit the making of payments
outside the United States or in a foreign currency, composite currency or
currency unit. In addition, I express no opinion with respect to any Debt
Securities that are indexed or linked to any foreign currency, composite
currency, currency unit, commodity, equity index or similar index.

          I hereby consent to the filing of this opinion with the Commission as
Exhibit 5 to the Registration Statement.  I also consent to the reference to me
under the heading "Legal Matters" in the Registration Statement.  In giving this
consent, I do not thereby admit that I am in the category of persons whose
consent is required under Section 7 of the Securities Act or the rules and
regulations of the Commission.


                         Very truly yours,

                   CONSENT OF INDEPENDENT PUBLIC ACCOUNTANTS


   We consent to the incorporation by reference in this Registration Statement
of Form S-3 of our report dated November 14, 1997, with respect to the
statements of financial position of the U.S. Department of Energy Naval
Petroleum Reserve No. 1 (NPR-1) as of September 30, 1997 and 1996, and the
related statements of operations and changes in net position, and cash flows for
the year then ended, which appears in Occidental Petroleum Corporation's Current
Report on Form 8-K dated February 10, 1998 (date of earliest event reported),
and to the reference to our Firm under the heading "Experts" in the prospectus.

   Our report dated November 14, 1997, contains an explanatory paragraph that 
states that the financial statements were prepared in conformity with the 
hierarchy of accounting principles and standards defined in U.S. Office of 
Management and Budget Bulletin No. 94-01, Form and Content of Agency Financial 
Statements. This hierarchy is a comprehensive basis of accounting other than 
generally accepted accounting principles.

   Our report dated November 14, 1997, contains an explanatory paragraph that 
states that on October 6, 1997, DOE announced that Occidental Petroleum 
Corporation had submitted the highest responsible offer at $3.65 billion for all
of the Government's interest in NPR-1.
