                             BANC ONE CORPORATION
 
  BANC ONE is a multi-bank holding company that, at March 31, 1995, had a
total of 65 bank subsidiaries (the "affiliate banks") in Arizona, Colorado,
Illinois, Indiana, Kentucky, Ohio, Oklahoma, Texas, Utah, West Virginia and
Wisconsin. At March 31, 1995, BANC ONE had consolidated total assets of $87.8
billion, consolidated total deposits of $65.4 billion and consolidated total
stockholders' equity of $7.7 billion (8.8% of its consolidated total assets).
At March 31, 1995, BANC ONE ranked 8th among the nation's publicly owned bank
holding companies in terms of consolidated average total assets and 6th in
terms of consolidated average common equity. BANC ONE's 1994 consolidated net
income of $1.01 billion ranked 7th among the nation's publicly owned bank
holding companies.
 
  At December 31, 1994 BANC ONE's affiliate banks held the largest statewide
share of total bank deposits in Arizona and Kentucky, the second largest share
of such deposits in Indiana, Ohio and West Virginia, and the third largest
share of such deposits in Colorado, Wisconsin and Texas. BANC ONE has smaller
statewide market shares in the other states in which BANC ONE operates banks.
At March 31, 1995, except for Bank One Texas, N.A., no single BANC ONE
affiliate bank accounted for more than 20% of BANC ONE's consolidated total
assets. BANC ONE also operates additional corporations that engage in data
processing, venture capital, investment and merchant banking, trust,
brokerage, investment management, equipment leasing, mortgage banking, credit
card, consumer finance and insurance.
 
  Since its formation in 1968, BANC ONE has acquired over 100 banking
institutions and the number of banking offices of its affiliate banks has
increased from 24 to over 1,400. BANC ONE continues to explore opportunities
to acquire banks and nonbank companies permitted by the Bank Holding Company
Act. Discussions are continually being carried on relating to such
acquisitions. It is not presently known whether, or on what terms, such
discussions will result in further acquisitions. Such acquisitions may be
pending, from time to time, during the time that the Debt Securities are being
offered. BANC ONE's acquisition strategy is flexible in that it does not
require BANC ONE to effect specific acquisitions so as to enter certain
markets or to attain specified growth levels. Rather than being market driven
or size motivated, BANC ONE's acquisition strategy reflects BANC ONE's
willingness to consider potential acquisitions wherever and whenever such
opportunities arise based on the then-existing market conditions and other
circumstances. Banks to be acquired must be of sufficient size to support and
justify having management of a caliber capable of making lending and other
management decisions at the local level under BANC ONE's operating philosophy.
BANC ONE also is willing from time to time to acquire a smaller bank when it
can be acquired through a reorganization into an existing affiliate. BANC
ONE's interest in the acquisition of nonbank companies has been limited to
bank-related services with which BANC ONE already has familiarity. BANC ONE's
acquisitions may be made by the exchange of stock, through cash purchases and
with other consideration.
 
  BANC ONE is a legal entity separate and distinct from its affiliate banks
and its nonbanking subsidiaries (collectively, the "affiliates"). Accordingly,
the right of BANC ONE, and thus the right of BANC ONE's creditors and
shareholders, to participate in any distribution of the assets or earnings of
any affiliate is necessarily subject to the prior claims of creditors of the
affiliate except to the extent that claims of BANC ONE in its capacity as a
creditor may be recognized. The principal sources of BANC ONE's revenues are
dividends and fees from its affiliates. See "Regulatory Matters" for a
discussion of the restrictions on the affiliate banks' ability to pay
dividends to BANC ONE.
 
  BANC ONE is incorporated in Ohio and has functioned as a multi-bank holding
company since 1968. Its executive offices are located at 100 East Broad
Street, Columbus, Ohio 43271, and its telephone number is (614) 248-5944.

  Earnings are comprised of income before income taxes, change in accounting
principle and equity in earnings of Bank One, Texas, N.A., plus fixed charges.
Fixed charges include interest expense (including the interest factor of
capitalized leases, capitalized interest and amortization of deferred debt
expense) plus the portion of rental payments under operating leases deemed to
be interest. Results of Bank One, Texas, N.A. are consolidated beginning
October 1, 1991.
 
                                USE OF PROCEEDS
 
  BANC ONE currently intends to use the net proceeds from the sale of any Debt
Securities for general corporate purposes, which may include the reduction of
short-term indebtedness, investments at the holding company level, investments
in or extensions of credit to its affiliates and other banks and companies
engaged in other financial service activities, possible acquisitions and such
other purposes as may be stated in any Prospectus Supplement. Pending such
use, the net proceeds may be temporarily invested. The precise amounts and
timing of the application of proceeds will depend upon the funding
requirements of BANC ONE and its affiliates and the availability of other
funds. Except as may be described in any Prospectus Supplement, specific
allocations of the proceeds to such purposes will not have been made at the
date of such Prospectus Supplement. Based upon the historical and anticipated
future growth of BANC ONE and the financial needs of its affiliates, BANC ONE
may engage in additional financings of a character and amount to be determined
as the need arises.
 
                              REGULATORY MATTERS
 
GENERAL
 
  BANC ONE is subject to the supervision of, and to regular inspection by, the
Board of Governors of the Federal Reserve System (the "Federal Reserve"). BANC
ONE's principal affiliate banks are organized as national banking
associations, which are subject to regulation by the Office of the Comptroller
of the Currency ("OCC"). In addition, various state authorities regulate BANC
ONE's state affiliate banks, and all of BANC ONE's affiliate banks are subject
to regulation in some degree by the Federal Reserve and the Federal Deposit
Insurance Corporation (the "FDIC"). In addition to banking laws, regulations
and regulatory agencies, BANC ONE and its affiliates are subject to various
other laws, regulations and regulatory agencies, all of which directly or
indirectly affect BANC ONE's operations, management and ability to make
distributions. The following discussion summarizes certain aspects of those
laws and regulations that affect BANC ONE.
 
  Proposals to change the laws and regulations governing the banking industry
are frequently raised in Congress, in the state legislatures and by the
various bank regulatory agencies. The likelihood and timing of any legislative
or regulatory changes and the impact such changes might have on BANC ONE and
its affiliates are difficult to determine.
 
  BANC ONE's affiliate banks are affected by various state and federal laws
and by the fiscal and monetary policies of the federal government and its
agencies, including the Federal Reserve. An important purpose of these fiscal
and monetary policies is to curb inflation and limit recessions through
control of the supply of money and credit. The Federal Reserve uses its powers
to regulate reserve requirements of its member banks, to set the discount rate
on extensions of credit to insured depository institutions and to conduct open
market operations in United States government securities so as to exercise
control over the supply of money and credit. These policies
 
                                       6
<PAGE>
 
directly affect the amount of, and the interest rates on, bank loans and
deposits, and this materially affects bank earnings. Future policies of the
Federal Reserve and other authorities and their effect on future bank earnings
cannot be predicted. Similarly, future changes in state and federal laws and
wage, price and other economic restraints of the federal government and their
effect on future bank earnings cannot be predicted.
 
HOLDING COMPANY STRUCTURE
 
  BANC ONE is a legal entity separate and distinct from its affiliates.
Accordingly, the right of BANC ONE, and thus the rights of BANC ONE's
creditors and shareholders, to participate in any distribution of the assets
or earnings of any affiliate is necessarily subject to the prior claims of
creditors of such affiliate, except to the extent that claims of BANC ONE in
its capacity as a creditor may be recognized. The principal sources of BANC
ONE's revenues are dividends and fees from its affiliates.
 
  BANC ONE's affiliate banks are subject to restrictions under federal law
which limit the transfer of funds by the affiliate banks to BANC ONE and its
nonbanking subsidiaries, whether in the form of loans, extensions of credit,
investments, or asset purchases. Such transfers by any affiliate bank to BANC
ONE or any nonbanking subsidiary are limited in amount to 10% of the bank's
capital and surplus and, with respect to the Corporation and all such
nonbanking subsidiaries, to an aggregate of 20% of such bank's capital and
surplus. Furthermore, such loans and extensions of credit are required to be
secured in specified amounts.
 
  The Federal Reserve has a policy to the effect that a bank holding company
is expected to act as a source of financial and managerial strength to each of
its subsidiary banks and to maintain resources adequate to support each such
subsidiary bank. This support may be required at times when BANC ONE may not
have the resources to provide it. Any capital loans by BANC ONE to any of the
affiliate banks are subordinate in right of payment to deposits and to certain
other indebtedness of such affiliate bank. In addition, in the event of a bank
holding company's bankruptcy any commitment by the bank holding company to a
federal bank regulatory agency to maintain the capital of a subsidiary bank
will be assumed by the bankruptcy trustee and entitled to a priority of
payment.
 
  A depository institution insured by the FDIC can be held liable for any loss
incurred by, or reasonably expected to be incurred by, the FDIC after August
9, 1989, in connection with (i) the default of a commonly controlled FDIC-
insured depository institution or (ii) any assistance provided by the FDIC to
a commonly controlled FDIC-insured depository institution in danger of
default. "Default" is defined generally as the appointment of a conservator or
receiver and "in danger of default" is defined generally as the existence of
certain conditions indicating that a "default" is likely to occur in the
absence of regulatory assistance.
 
  Federal law (12 U.S.C. Section 55) permits the OCC to order the pro rata
assessment of shareholders of a national bank whose capital stock has become
impaired, by losses or otherwise, to relieve a deficiency in such national
bank's capital stock. This statute also provides for the enforcement of any
such pro rata assessment of shareholders of such national bank to cover such
impairment of capital stock by sale, to the extent necessary, of the capital
stock of any assessed shareholder failing to pay the assessment. Similarly,
the laws of certain states provide for such assessment and sale with respect
to banks chartered by such states. BANC ONE, as the sole shareholder of its
affiliate national banks, is subject to such provisions.
 
CAPITAL REQUIREMENTS
 
  BANC ONE is subject to capital ratios, requirements and guidelines imposed
by the Federal Reserve, which are substantially similar to the ratios,
requirements and guidelines imposed by the Federal Reserve, the OCC and the
FDIC on the banks within their respective jurisdictions. These capital
requirements establish higher capital standards for banks and bank holding
companies that assume greater credit risks. For this purpose, a bank's or
holding company's assets and certain specified off-balance sheet commitments
are assigned to four risk categories, each weighted differently based on the
level of credit risk that is ascribed to such assets or commitments. A bank's
or holding company's capital, in turn, is divided into two tiers: core ("Tier
1") capital, which includes common equity, non-cumulative perpetual preferred
stock and related surplus (excluding auction
 
                                       7
<PAGE>
 
rate issues), and minority interests in equity accounts of consolidated
subsidiaries, less goodwill, certain identifiable intangible assets and
certain other assets; and supplementary ("Tier 2") capital, which includes,
among other items, perpetual preferred stock not meeting the Tier 1
definition, mandatory convertible securities, subordinated debt and allowances
for loan and lease losses, subject to certain limitations, less certain
required deductions.
 
  BANC ONE, like other bank holding companies, currently is required to
maintain Tier 1 and total capital (the sum of Tier 1 and supplementary
capital) equal to at least 4% and 8% of its total risk-weighted assets,
respectively. At March 31, 1995 BANC ONE met both requirements, with Tier 1
and total capital equal to 10.23% and 13.62% of its total risk-weighted
assets, respectively.
 
  The Federal Reserve also requires bank holding companies to maintain a
minimum "leverage ratio" (Tier 1 capital to adjusted total assets) of 3%, if
the holding company has the highest regulatory rating and meets certain other
requirements, or of 3% plus an additional cushion of at least 100 to 200 basis
points if the holding company does not meet these requirements. At March 31,
1995 BANC ONE's leverage ratio was 8.58%.
 
  The Federal Reserve may set capital requirements higher than the minimums
noted above for holding companies whose circumstances warrant it. For example,
holding companies experiencing or anticipating significant growth may be
expected to maintain capital ratios including tangible capital positions well
above the minimum levels. The Federal Reserve has not, however, imposed any
such special capital requirement on BANC ONE.
 
  On September 14, 1993, the Federal Reserve, the FDIC and the OCC issued a
joint notice of proposed rulemaking, soliciting comments on a proposal to
revise their risk-based capital standards to take account of interest rate
risk. The notices propose alternative approaches for determining the
additional amount of capital, if any, that may be required to compensate for
interest rate risk. The first approach would reduce a depository institution's
risk-based capital ratio by an amount based on its measured exposure to
interest rate risk in excess of a specified threshold. The second approach
would assess the need for additional capital on a case-by-case basis,
considering both the level of measured exposure and qualitative risk factors.
BANC ONE cannot assess at this point the impact, if any, that such proposals
would have on its capital ratios.
 
DIVIDEND RESTRICTIONS
 
  Various federal and state statutory provisions limit the amount of dividends
BANC ONE's affiliate banks can pay to BANC ONE without regulatory approval.
The approval of the appropriate bank regulator is required for any dividend by
a national bank or by a state-chartered bank that is a member of the Federal
Reserve System (a "state member bank") if the total of all dividends declared
by the bank in any calendar year would exceed the total of its net profits, as
defined by regulatory agencies, for such year combined with its retained net
profits for the preceding two years. In addition, a national bank or a state
member bank may not pay a dividend in an amount greater than its net profits
then on hand. At December 31, 1994, total stockholders' equity of the
affiliate banks approximated $7.2 billion, of which $1.4 billion was available
for payment of dividends to BANC ONE without approval by the applicable
regulatory authority.
 
  In addition, federal bank regulatory authorities have authority to prohibit
the affiliate banks from engaging in an unsafe or unsound practice in
conducting their business. The payment of dividends, depending upon the
financial condition of the bank in question, could be deemed to constitute
such an unsafe or unsound practice. The ability of BANC ONE's affiliate banks
to pay dividends in the future is presently, and could be further, influenced
by bank regulatory policies and capital guidelines.
 
FEDERAL DEPOSIT INSURANCE CORPORATION IMPROVEMENT ACT OF 1991
 
  The Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA")
significantly expanded the regulatory and enforcement powers of federal
banking regulators, in particular the FDIC, and has important consequences for
BANC ONE, its affiliate banks and other depository institutions located in the
United States.
 
 
                                       8
<PAGE>
 
  A major feature of FDICIA is the comprehensive directions it gives to
federal banking regulators to promptly direct or require the correction of
problems at inadequately capitalized banks in the manner that is least costly
to the federal deposit insurance funds. The degree of corrective regulatory
involvement in the operations and management of banks and their holding
companies is, under FDICIA, largely determined by the actual or anticipated
capital positions of the subject institution.
 
  FDICIA established five tiers of capital measurement for regulatory purposes
ranging from "well capitalized" to "critically undercapitalized." Under
regulations adopted by the federal banking agencies, a depository institution
is well capitalized if it significantly exceeds the minimum level required by
regulation for each relevant capital measure, adequately capitalized if it
meets such measure, undercapitalized if it fails to meet any such measure,
significantly undercapitalized if it is significantly below such measure and
critically undercapitalized if its tangible equity is not greater than 2% of
total tangible assets. A depository institution may be deemed to be in a
capitalization category lower than is indicated by its actual capital position
if it receives an unsatisfactory examination rating. FDICIA requires banking
regulators to take increasingly strong corrective steps, based on the capital
tier of any subject bank, to cause such bank to achieve and maintain capital
adequacy. Even if a bank is adequately capitalized, however, the banking
regulators are authorized to apply corrective measures if the bank is
determined to be in an unsafe or unsound condition or engaging in an unsafe or
unsound activity.
 
  Depending on the level of capital of an insured depository institution, the
banking regulatory agencies' corrective powers can include: requiring a
capital restoration plan; placing limits on asset growth and restrictions on
activities; requiring the institution to reduce total assets; requiring the
institution to issue additional stock (including voting stock) or to be
acquired; placing restrictions on transactions with affiliates; restricting
the interest rate the institution may pay on deposits; ordering a new election
for the institution's board of directors; requiring that certain senior
executive officers or directors be dismissed; prohibiting the institution from
accepting deposits from correspondent banks; requiring the institution to
divest certain subsidiaries; prohibiting the payment of principal or interest
on subordinated debt; prohibiting the institution's parent bank holding
company from making capital distributions without prior regulatory approval;
and, ultimately, appointing a conservator or receiver for the institution.
 
  If the insured depository institution is undercapitalized, the parent bank
holding company is required to guarantee that the institution will comply with
any capital restoration plan submitted to, and approved by, the appropriate
federal banking agency in an amount equal to the lesser of (i) 5% of the
institution's total assets at the time the institution became undercapitalized
or (ii) the amount which is necessary (or would have been necessary) to bring
the institution into compliance with all applicable capital standards as of
the time the institution failed to comply with the capital restoration plan.
If such parent bank holding company guarantee is not obtained, the capital
restoration plan may not be accepted by the banking regulators. As a result,
such institution would be subject to the more severe restrictions imposed on
significantly undercapitalized institutions. Further, the failure of such a
depository institution to submit an acceptable capital plan is grounds for the
appointment of a conservator or receiver.
 
  FDICIA also contains a number of other provisions affecting depository
institutions, including additional reporting and independent auditing
requirements, the establishment of safety and soundness standards, the
changing of FDIC insurance premiums from flat amounts to the system of risk-
based assessments described below under "Deposit Insurance Assessments", a
review of accounting standards, and supplemental disclosures and limits on the
ability of all but well capitalized depository institutions to acquire
brokered deposits. The Riegle-Community Development and Regulatory Improvement
Act of 1994, however, among other things, contains a number of specific
provisions easing the regulatory burden on banks and bank holding companies,
including some imposed by FDICIA, and making the bank regulatory system more
efficient. Federal banking regulators are taking actions to implement these
provisions.
 
 
                                       9

DEPOSIT INSURANCE ASSESSMENTS
 
  The deposits of each of BANC ONE's affiliate banks are insured up to
regulatory limits by the FDIC and, accordingly, are subject to deposit
insurance assessments to maintain the Bank Insurance Fund ("BIF") administered
by the FDIC. The FDIC has adopted regulations establishing a permanent risk-
related deposit insurance assessment system. Under this system, the FDIC
places each insured bank in one of nine risk categories based on (a) the
bank's capitalization and (b) supervisory evaluations provided to the FDIC by
the institution's primary federal regulator. Each insured bank's insurance
assessment rate is then determined by the risk category in which it is
classified by the FDIC. There is currently an eight basis point spread between
the highest and lowest assessment rates, so that banks classified in the
highest capital and supervisory evaluation categories by the FDIC are
currently subject to a rate of $0.23 per $100 of deposits and banks classified
in the lowest capital and supervisory evaluation categories by the FDIC are
currently subject to a rate of $0.31 per $100 of deposits.
 
  These assessment rates also reflect the amount the FDIC has determined is
necessary to increase the reserve ratio of the BIF to 1.25% of total insured
bank deposits. Under FDICIA, the FDIC is required to increase the reserve
ratio to this level by 2006. In fact, the FDIC has announced that this reserve
ratio will be achieved during 1995, and has proposed a new, and significantly
lower, assessment rate schedule for BIF-insured deposits. However, due
primarily to the fact that the reserve ratio of the FDIC's Savings Association
Insurance Fund ("SAIF") is not projected to reach the required level for
several years, it is uncertain when, and whether, the FDIC's proposed new
schedule of BIF assessment rates will take effect. BIF assessments will be
subject to adjustment and it is possible that there may be special additional
assessments.
 
  Some BANC ONE affiliate banks hold deposits that were acquired from savings
institutions and that, accordingly, are insured by SAIF. At March 31, 1995,
BANC ONE's affiliate banks held $6.3 billion of such deposits. Deposit
insurance premiums may, from time to time, be charged at a higher rate for
SAIF than for BIF- insured deposits. That, indeed, would be the case were the
FDIC's proposed reduction in BIF assessment rates to take effect as proposed.
 
DEPOSITOR PREFERENCE STATUTE
 
  Federal legislation has been enacted providing that deposits and certain
claims for administrative expenses and employee compensation against an
insured depository institution would be afforded a priority over other general
unsecured claims against such institution, including federal funds and letters
of credit, in the "liquidation or other resolution" of the institution by any
receiver.
 
BROKERED DEPOSITS
 
  Under FDIC regulations, no FDIC-insured bank or savings institution can
accept brokered deposits unless it (a) is well capitalized, or (b) is
adequately capitalized and receives a waiver from the FDIC. In addition, these
regulations prohibit any bank or savings institution that is not well
capitalized from (a) paying an interest rate on deposits in excess of 75 basis
points over certain prevailing market rates, or (b) offering "pass through"
deposit insurance on certain employee benefit plan accounts unless it provides
certain notice to affected depositors. At March 31, 1995, BANC ONE's affiliate
banks had aggregate total brokered deposits of approximately $96 million.
 
INTERSTATE BANKING
 
  Under the Riegle-Neal Interstate Banking and Branching Efficiency Act of
1994 ("Riegle-Neal"), subject to certain concentration limits, (a) bank
holding companies such as BANC ONE are permitted, beginning September 29,
1995, to acquire banks and bank holding companies located in any state; (b)
any bank that is a subsidiary of a bank holding company is permitted, again
beginning September 29, 1995, to receive deposits, renew time deposits, close
loans, service loans and receive loan payments as an agent for any other bank
subsidiary of that holding company; and (c) banks are permitted, beginning
June 1, 1997, to acquire branch
 
                                      10
<PAGE>
 
offices outside their home states by merging with out-of-state banks,
purchasing branches in other states, and establishing de novo branch offices
in other states, provided that, in the case of any such purchase or opening of
individual branches, the host state has adopted legislation "opting in" to
those provisions of Riegle-Neal; and provided that, in the case of a merger
with a bank located in another state, the host state has not adopted
legislation "opting out" of that provision of Riegle-Neal. BANC ONE might use
Riegle-Neal to acquire banks in additional states and to consolidate its bank
subsidiaries under a smaller number of separate charters.
 
                        DESCRIPTION OF DEBT SECURITIES
 
GENERAL
   
  The Debt Securities will constitute either Senior Securities or Subordinated
Securities. The Senior Securities will be issued under an Indenture (the
"Senior Indenture") between BANC ONE and the trustee named in the applicable
Prospectus Supplement as trustee (the "Senior Trustee"). The Subordinated
Securities will be issued under an Indenture dated as of July 1, 1995 (the
"Subordinated Indenture"), between BANC ONE and Citibank, N.A., as Trustee
("Citibank"). The Senior Indenture and the Subordinated Indenture are
collectively referred to herein as the "Indentures". References to the
"Trustee" shall mean the Senior Trustee or Citibank, as applicable. The
statements under this caption are brief summaries of certain provisions
contained in the Indentures, do not purport to be complete and are qualified
in their entirety by reference to the applicable Indenture, copies of which
are exhibits to the Registration Statement. Whenever defined terms are used
but not defined herein, such terms shall have the meanings ascribed to them in
the applicable Indenture, it being intended that such defined terms shall be
incorporated herein by reference.     
 
  The following description of the terms of the Debt Securities sets forth
certain general terms and provisions of the Debt Securities to which any
Prospectus Supplement may relate. The particular terms of any Debt Securities
and the extent, if any, to which such general provisions may apply to such
Debt Securities will be described in the Prospectus Supplement relating to
such Debt Securities.
 
  Neither of the Indentures limits the amount of Debt Securities which may be
issued thereunder, and each Indenture provides that Debt Securities of any
series may be issued thereunder up to the aggregate principal amount which may
be authorized from time to time by BANC ONE and may be denominated in any
currency or currency unit designated by BANC ONE. Neither the Indentures nor
the Debt Securities will limit or otherwise restrict the amount of other
indebtedness which may be incurred or the other securities which may be issued
by BANC ONE or any of its subsidiaries.
 
  Debt Securities of a series may be issuable in registered form without
coupons ("Registered Securities"), in bearer form with or without coupons
attached ("Bearer Securities") or in the form of one or more global securities
in registered or bearer form (each a "Global Security"). Bearer Securities, if
any, will be offered only to non-United States persons and to offices located
outside the United States of certain United States financial institutions.
Reference is made to the Prospectus Supplement for a description of the
following terms, where applicable, of each series of Debt Securities in
respect of which this Prospectus is being delivered: (1) the title of such
Debt Securities; (2) the limit, if any, on the aggregate principal amount or
aggregate initial public offering price of such Debt Securities; (3) the
priority of payment of such Debt Securities; (4) the price or prices (which
may be expressed as a percentage of the aggregate principal amount thereof) at
which the Debt Securities will be issued; (5) the date or dates on which the
principal of the Debt Securities will be payable; (6) the rate or rates (which
may be fixed or variable) per annum at which such Debt Securities will bear
interest, if any, or the method of determining the same; (7) the date or dates
from which such interest, if any, on the Debt Securities will accrue, the date
or dates on which such interest, if any, will be payable, the date or dates on
which payment of such interest, if any, will commence and the Regular Record
Dates for such Interest Payment Dates; (8) the extent to which any of the Debt
Securities will be issuable in temporary or permanent global form, or the
manner in which any interest payable on a temporary or permanent global Debt
Security will be paid; (9) each office or agency where, subject to the terms
of the applicable Indenture, the Debt Securities may be presented for
registration of
 
                                      11
<PAGE>
 
transfer or exchange; (10) the place or places where the principal of (and
premium, if any) and interest, if any, on the Debt Securities will be payable;
(11) the date or dates, if any, after which such Debt Securities may be
redeemed or purchased in whole or in part, at the option of BANC ONE or
mandatorily pursuant to any sinking, purchase or analogous fund or may be
required to be purchased or redeemed at the option of the holder, and the
redemption or repayment price or prices thereof; (12) the denomination or
denominations in which such Debt Securities are authorized to be issued; (13)
the currency, currencies or units (including ECU) based on or related to
currencies for which the Debt Securities may be purchased and the currency,
currencies or currency units (including ECU) in which the principal of,
premium, if any, and any interest on such Debt Securities may be payable; (14)
any index used to determine the amount of payments of principal of, premium,
if any, and interest on the Debt Securities; (15) whether any of the Debt
Securities are to be issuable as Bearer Securities and/or Registered
Securities, and if issuable as Bearer Securities, any limitations on issuance
of such Bearer Securities and any provisions regarding the transfer or
exchange of such Bearer Securities (including exchange for registered Debt
Securities of the same series); (16) the payment of any additional amounts
with respect to the Debt Securities; (17) whether any of the Debt Securities
will be issued as Original Issue Discount Securities (as defined below); (18)
information with respect to book-entry procedures, if any; (19) any additional
covenants or Events of Default not currently set forth in the applicable
Indenture; and (20) any other terms of such Debt Securities not inconsistent
with the provisions of the applicable Indenture.
   
  If any of the Debt Securities are sold for one or more foreign currencies or
foreign currency units or if the principal of, premium, if any, or interest on
any series of Debt Securities is payable in one or more foreign currencies or
foreign currency units, the restrictions, elections, tax consequences,
specific terms and other information with respect to such issue of Debt
Securities and such currencies or currency units will be set forth in the
Prospectus Supplement relating thereto. A judgment for money damages by courts
in the United States, including a money judgment based on an obligation
expressed in a foreign currency, will ordinarily be rendered only in U.S.
dollars. New York statutory law provides that a court shall render a judgment
or decree in the foreign currency of the underlying obligation and that the
judgment or decree shall be converted into U.S. dollars at the exchange rate
prevailing on the date of entry of the judgment or decree.     
 
  Debt Securities may be issued as original issue discount Debt Securities
(bearing no interest or interest at a rate which at the time of issuance is
below market rates) ("Original Issue Discount Securities"), to be sold at a
substantial discount below the stated principal amount thereof due at the
stated maturity of such Debt Securities. There may not be any periodic
payments of interest on Original Issue Discount Securities as defined herein.
In the event of an acceleration of the maturity of any Original Issue Discount
Security, the amount payable to the holder of such Original Issue Discount
Security upon such acceleration will be determined in accordance with the
Prospectus Supplement, the terms of such security and the Indenture, but will
be an amount less than the amount payable at the maturity of the principal of
such Original Issue Discount Security. Federal income tax considerations with
respect to Original Issue Discount Securities will be set forth in the
Prospectus Supplement relating thereto.
 
REGISTRATION AND TRANSFER
 
  Unless otherwise indicated in the applicable Prospectus Supplement, Debt
Securities will be issued only as Registered Securities. If Bearer Securities
are issued, the United States Federal income tax consequences and other
special considerations, procedures and limitations applicable to such Bearer
Securities will be described in the Prospectus Supplement relating thereto.
 
  Debt Securities issued as Registered Securities will be without coupons.
Debt Securities issued as Bearer Securities shall have interest coupons
attached, unless issued as zero coupon securities.
 
  Registered Securities (other than a Global Security) may be presented for
transfer (with the form of transfer endorsed thereon duly executed) or
exchanged for other Debt Securities of the same series at the office of the
 
                                      12
<PAGE>
 
Note Registrar specified according to the terms of the applicable Indenture.
BANC ONE has agreed in each of the Indentures that, with respect to Registered
Securities having The City of New York as a place of payment, BANC ONE will
appoint a Note Registrar or Co-Note Registrar located in The City of New York
for such transfer or exchange. Such transfer or exchange shall be made without
service charge, but BANC ONE may require payment of any taxes or other
governmental charges as described in the applicable Indenture. Provisions
relating to the exchange of Bearer Securities for other Debt Securities of the
same series (including, if applicable, Registered Securities) will be
described in the applicable Prospectus Supplement. In no event, however, will
Registered Securities be exchangeable for Bearer Securities.
 
GLOBAL SECURITIES
 
  The Debt Securities of a series may be issued in whole or in part in the
form of one or more Global Securities that will be deposited with, or on
behalf of, a depositary (the "Depositary") identified in the Prospectus
Supplement relating to such series. Global Securities may be issued in either
registered or bearer form and in either temporary or permanent form. Unless
and until it is exchanged in whole or in part for the individual Debt
Securities represented thereby, a Global Security may not be transferred
except as a whole by the Depositary for such Global Security to a nominee of
such Depositary or by a nominee of such Depositary to such Depositary or
another nominee of such Depositary or by the Depositary or any nominee to a
successor Depositary or any nominee of such successor.
 
  The specific terms of the depositary arrangement with respect to a series of
Debt Securities and certain limitations and restrictions relating to a series
of Bearer Securities in the form of one or more Global Securities, will be
described in the Prospectus Supplement relating to such series. BANC ONE
anticipates that the following provisions will generally apply to depositary
arrangements.
 
  Upon the issuance of a Global Security, the Depositary for such Global
Security or its nominee will credit, on its book-entry registration and
transfer system, the respective principal amounts of the individual Debt
Securities represented by such Global Security to the accounts of persons that
have accounts with such Depositary. Such accounts shall be designated by the
underwriters or agents with respect to such Debt Securities. Ownership of
beneficial interests in a Global Security will be limited to persons that have
accounts with the applicable Depositary ("participants") or persons that may
hold interests through participants. Ownership of beneficial interests in such
Global Security will be shown on, and the transfer of that ownership will be
effected only through, records maintained by the applicable Depositary or its
nominee (with respect to interests of participants) and the records of
participants (with respect to interests of persons other than participants).
The laws of some states require that certain purchasers of securities take
physical delivery of such securities in definitive form. Such limits and such
laws may impair the ability to transfer beneficial interests in a Global
Security.
 
  So long as the Depositary for a Global Security, or its nominee, is the
registered owner of such Global Security, such Depositary or such nominee, as
the case may be, will be considered the sole owner or holder of the Debt
Securities represented by such Global Security for all purposes under the
Indenture governing such Debt Securities. Except as provided below, owners of
beneficial interests in a Global Security will not be entitled to have any of
the individual Debt Securities of the series represented by such Global
Security registered in their names, will not receive or be entitled to receive
physical delivery of any such Debt Securities of such series in definitive
form and will not be considered the owners or holders thereof under the
Indenture governing such Debt Securities.
 
  Payments of principal of, premium, if any, and interest, if any, on
individual Debt Securities represented by a Global Security registered in the
name of a Depositary or its nominee will be made to the Depositary or its
nominee, as the case may be, as the registered owner of the Global Security
representing such Debt Securities. Neither BANC ONE, the Trustee for such Debt
Securities, any Paying Agent, nor the Note Registrar for such Debt Securities
will have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interests of
the Global Security for such Debt Securities or for maintaining, supervising
or reviewing any records relating to such beneficial ownership interests.
 
                                      13
<PAGE>
 
  Subject to certain restrictions relating to Bearer Securities, BANC ONE
expects that the Depositary for a series of Debt Securities or its nominee,
upon receipt of any payment of principal, premium or interest in respect of a
permanent Global Security representing any of such Debt Securities will credit
participants' accounts immediately with payments in amounts proportionate to
their respective beneficial interests in the principal amount of such Global
Security for such Debt Securities as shown on the records of such Depositary
or its nominee. BANC ONE also expects that payments by participants to owners
of beneficial interests in such Global Security held through such participants
will be governed by standing instructions and customary practices, as is now
the case with securities held for the accounts of customers in bearer form or
registered in "street name". Such payments will be the responsibility of such
participants. With respect to owners of beneficial interests in a temporary
Global Security representing Bearer Securities, receipt by such beneficial
owners of payments of principal, premium or interest in respect thereof will
be subject to additional restrictions.
 
  If the Depositary for a series of Debt Securities is at any time unwilling,
unable or ineligible to continue as depositary and a successor depositary is
not appointed by BANC ONE within 90 days, BANC ONE will issue individual Debt
Securities of such series in definitive form in exchange for the Global
Security representing such series of Debt Securities. In addition, BANC ONE
may at any time and in its sole discretion, subject to any limitations
described in the Prospectus Supplement relating to such Debt Securities,
determine not to have any Debt Securities of a series represented by one or
more Global Securities and, in such event, will issue individual Debt
Securities of such series in definitive form in exchange for the Global
Security or Securities representing such series of Debt Securities. Further,
if BANC ONE so specifies with respect to the Debt Securities of a series, an
owner of a beneficial interest in a Global Security representing Debt
Securities of such series may, on terms acceptable to BANC ONE, the Trustee
and the Depositary for such Global Security, receive Debt Securities of such
series in definitive form in exchange for such beneficial interests, subject
to any limitations described in the Prospectus Supplement relating to such
Debt Securities. In any such instance, an owner of a beneficial interest in a
Global Security will be entitled to physical delivery in definitive form of
Debt Securities of the series represented by such Global Security equal in
principal amount to such beneficial interest and to have such Debt Securities
registered in its name (if the Debt Securities of such series are issuable as
Registered Securities). Debt Securities of such series so issued in definitive
form will be issued (a) as Registered Securities in denominations, unless
otherwise specified by BANC ONE, of $1,000 and integral multiples thereof if
the Debt Securities of such series are issuable as Registered Securities, (b)
as Bearer Securities in the denomination, unless otherwise specified by BANC
ONE, of $5,000 if the Debt Securities of such series are issuable as Bearer
Securities or (c) as either Registered or Bearer Securities, if the Debt
Securities of such series are issuable in either form. Certain restrictions
may apply, however, on the issuance of a Bearer Security in definitive form in
exchange for an interest in a Global Security.
 
PAYMENT AND PAYING AGENTS
 
  Unless otherwise indicated in an applicable Prospectus Supplement, payment
of principal of, premium, if any, and any interest on Registered Securities
will be made at the office of such Paying Agent or Paying Agents as BANC ONE
may designate from time to time, except that, at the option of BANC ONE,
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 applicable Note
Register or (ii) by wire transfer to an account maintained by the person
entitled thereto as specified in the applicable Note Register. Unless
otherwise indicated in an applicable Prospectus Supplement, payment of any
installment of interest on Registered Securities will be made to the person in
whose name such Debt Security is registered at the close of business on the
Regular Record Date for such payment.
 
  Unless otherwise indicated in an applicable Prospectus Supplement, payment
of principal of, premium, if any, and any interest on Bearer Securities will
be payable, subject to any applicable laws and regulations, at the offices of
such Paying Agents outside the United States as BANC ONE may designate from
time to time, at the option of the Holder, by check or by transfer to an
account maintained by the payee with a bank located outside the United States.
Unless otherwise indicated in an applicable Prospectus Supplement, payment of
interest on
 
                                      14
<PAGE>
 
Bearer Securities will be made only against surrender of the coupon relating
to such Interest Payment Date. No payment with respect to any Bearer Security
will be made at any office or agency of BANC ONE in the United States or by
check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States.
 
CONSOLIDATION, MERGER OR SALE OF ASSETS
 
  Each Indenture provides that BANC ONE may, without the consent of the
holders of any of the Debt Securities outstanding under the applicable
Indenture, consolidate with, merge into or transfer its assets substantially
as an entirety to any person, provided that (i) any such successor assumes
BANC ONE's obligations on the applicable Debt Securities and under the
applicable Indenture, (ii) after giving effect thereto, no Event of Default
(as defined in the Senior Indenture) in the case of the Senior Securities, or
Default (as defined in the Subordinated Indenture) in the case of the
Subordinated Securities, shall have happened and be continuing and (iii)
certain other conditions under the applicable Indenture are met. Accordingly,
any such consolidation, merger or transfer of assets substantially as an
entirety, which meets the conditions described above, would not create any
Event of Default or Default which would entitle holders of the Debt
Securities, or the Trustee on their behalf, to take any of the actions
described below under "Senior Securities--Events of Default, Waivers, etc." or
"Subordinated Securities--Events of Default, Waivers, etc."
 
LEVERAGED AND OTHER TRANSACTIONS
 
  Each Indenture and the Debt Securities do not contain, among other things,
provisions which would afford holders of the Debt Securities protection in the
event of a highly leveraged or other transaction involving BANC ONE which
could adversely affect the holders of Debt Securities.
 
MODIFICATION OF THE INDENTURE; WAIVER OF COVENANTS
 
  Each Indenture provides that, with the consent of the holders of not less
than a majority in aggregate principal amount of the outstanding Debt
Securities of each affected series, modifications and alterations of such
Indenture may be made which affect the rights of the holders of such Debt
Securities; provided, however, that no such modification or alteration may be
made without the consent of the holder of each Debt Security so affected which
would, among other things, (i) change the maturity of the principal of, or of
any installment of interest (or premium, if any) on, any Debt Security issued
pursuant to such Indenture, or reduce the principal amount thereof or any
premium thereon, or change the method of calculation of interest or the
currency of payment of principal or interest (or premium, if any) on, or
reduce the minimum rate of interest thereon, or impair the right to institute
suit for the enforcement of any such payment on or with respect to any such
Debt Security, or reduce the amount of principal of an Original Issue Discount
Security that would be due and payable upon an acceleration of the maturity
thereof; or (ii) reduce the above-stated percentage in principal amount of
outstanding Debt Securities required to modify or alter such Indenture.
 
                               SENIOR SECURITIES
 
  The Senior Securities will be direct, unsecured obligations of BANC ONE and
will rank pari passu with all outstanding unsecured senior indebtedness of
BANC ONE.
 
EVENTS OF DEFAULT, WAIVERS, ETC.
 
  An Event of Default with respect to Senior Securities of any series is
defined in the Senior Indenture as (i) default in the payment of principal of
or premium, if any, on any of the Senior Securities of that series outstanding
under the Senior Indenture when due; (ii) default in the payment of interest
on any of the Senior Securities of that series outstanding under the Senior
Indenture when due and continuance of such default for 30 days; (iii) default
in the performance of any other covenant of BANC ONE in the Senior Indenture
with respect to Senior Securities of such series and continuance of such
default for 90 days after written notice; (iv) certain
 
                                      15
<PAGE>
 
events of bankruptcy, insolvency or reorganization of BANC ONE and (v) any
other event that may be specified in a Prospectus Supplement with respect to
any series of Senior Securities.
 
  If an Event of Default with respect to any series of Senior Securities for
which there are Senior Securities outstanding under the Senior Indenture
occurs and is continuing, either the applicable Trustee or the holders of not
less than 25% in aggregate principal amount of the Senior Securities of such
series outstanding may declare the principal amount (or if such Senior
Securities are Original Issue Discount Securities, such portion of the
principal amount as may be specified in the terms of that series) of all
Senior Securities of that series to be immediately due and payable. The
holders of a majority in aggregate principal amount of the Senior Securities
of any series outstanding under the Senior Indenture may waive an Event of
Default resulting in acceleration of such Senior Securities, but only if all
Events of Default with respect to Senior Securities of such series have been
remedied and all payments due (other than those due as a result of
acceleration) have been made. If an Event of Default occurs and is continuing,
the applicable Trustee may, in its discretion, and at the written request of
holders of not less than a majority in aggregate principal amount of the
Senior Securities of any series outstanding under the Senior Indenture and
upon reasonable indemnity against the costs, expenses and liabilities to be
incurred in compliance with such request and subject to certain other
conditions set forth in the Senior Indenture shall, proceed to protect the
rights of the holders of all the Senior Securities of such series. Prior to
acceleration of maturity of the Senior Securities of any series outstanding
under the Senior Indenture, the holders of a majority in aggregate principal
amount of such Senior Securities may waive any past default under the Senior
Indenture except a default in the payment of principal of, premium, if any, or
interest on the Senior Securities of such series.
 
  The Senior Indenture provides that upon the occurrence of an Event of
Default specified in clauses (i) or (ii) of the first paragraph under "--
Events of Defaults, Waivers, etc.", BANC ONE will, upon demand of the
applicable Trustee, pay to it, for the benefit of the holder of any such
Senior Security, the whole amount then due and payable on such Senior
Securities for principal, premium, if any, and interest. The Senior Indenture
further provides that if BANC ONE fails to pay such amount forthwith upon such
demand, such Trustee may, among other things, institute a judicial proceeding
for the collection thereof.
 
  The Senior Indenture also provides that notwithstanding any other provision
of the Senior Indenture, the holder of any Senior Security of any series shall
have the right to institute suit for the enforcement of any payment of
principal of, premium, if any, and interest on such Senior Securities when due
and that such right shall not be impaired without the consent of such holder.
 
  BANC ONE is required to file annually with the Trustee a written statement
of officers as to the existence or non-existence of defaults under the Senior
Indenture or the Senior Securities.
 
                            SUBORDINATED SECURITIES
 
  The Subordinated Securities will be direct, unsecured obligations of BANC
ONE and will be subject to the subordination provisions described below.
 
SUBORDINATION
 
  It is the intent of BANC ONE that Subordinated Securities issued by BANC ONE
be treated as capital for calculation of regulatory capital ratios. The
Federal Reserve has issued interpretations of its capital regulations
indicating, among other things, that subordinated debt of bank holding
companies issued on or after September 4, 1992, is includable in capital for
calculation of regulatory capital ratios only if the subordination of the debt
meets certain criteria and if the debt may be accelerated only for bankruptcy,
insolvency and similar matters (the "Subordination Interpretations").
Accordingly, the Subordinated Indenture contains subordination and
acceleration provisions for the Subordinated Securities which are intended to
be consistent with the
 
                                      16
<PAGE>
 
Subordination Interpretations. Subordinated debt of BANC ONE issued after
September 4, 1992, which meets the Subordination Interpretations are referred
to herein as "New Subordinated Securities". Unless otherwise specified in the
Prospectus Supplement relating to a particular series of Subordinated
Securities offered thereby, Subordinated Securities offered pursuant to this
Prospectus will constitute New Subordinated Securities. See "Events of
Default, Defaults, Waivers, etc." below.
 
  Upon any distribution of assets of BANC ONE upon any dissolution, winding
up, liquidation or reorganization, the payment of the principal of, premium,
if any, and interest on the Subordinated Securities is to be subordinated in
right of payment, to the extent provided in the Subordinated Indenture, to the
prior payment in full of all Senior Indebtedness. In certain events of
bankruptcy or insolvency, the payment of the principal of and interest on the
Subordinated Securities (and other New Subordinated Securities) will, to the
extent provided in the Subordinated Indenture, also be effectively
subordinated in right of payment to the prior payment in full of all General
Obligations.
 
  Upon any distribution of assets of BANC ONE upon any dissolution, winding
up, liquidation or reorganization, the holders of Senior Indebtedness will
first be entitled to receive payment in full of all amounts due or to become
due before the holders of the Subordinated Securities will be entitled to
receive any payment in respect of the principal of, premium, if any, or
interest on the Subordinated Securities. If upon any such payment or
distribution of assets there remain, after giving effect to such subordination
provisions in favor of the holders of Senior Indebtedness, any amounts of
cash, property or securities available for payment or distribution in respect
of the New Subordinated Securities ("Excess Proceeds") and if, at such time,
any creditors in respect of General Obligations have not received payment in
full of all amounts due or to become due on or in respect of such General
Obligations, then such Excess Proceeds shall first be applied to pay or
provide for the payment in full of such General Obligations before any payment
or distribution may be made in respect of the New Subordinated Securities.
 
  In addition, no payment may be made of the principal of, premium, if any, or
interest on the Subordinated Securities, or in respect of any redemption,
retirement, purchase or other acquisition of any of the Subordinated
Securities, at any time when (i) there is a default in the payment of the
principal of, premium, if any, interest on or otherwise in respect of any
Senior Indebtedness or (ii) any event of default with respect to any Senior
Indebtedness has occurred and is continuing, or would occur as a result of
such payment on the Subordinated Securities or any redemption, retirement,
purchase or other acquisition of any of the Subordinated Securities,
permitting the holders of such Senior Indebtedness to accelerate the maturity
thereof. Except as described above, the obligation of BANC ONE to make payment
of the principal of, premium, if any, or interest on the Subordinated
Securities will not be affected.
 
  By reason of such subordination in favor of the holders of Senior
Indebtedness, in the event of a distribution of assets upon any dissolution,
winding up, liquidation or reorganization, certain creditors of BANC ONE who
are not holders of Senior Indebtedness or of the Subordinated Securities may
recover less, ratably, than holders of Senior Indebtedness and may recover
more, ratably, than holders of the Subordinated Securities. By reason of the
obligation of the holders of New Subordinated Securities to pay over any
Excess Proceeds to creditors in respect of General Obligations, in the event
of a distribution of assets upon any dissolution, winding up, liquidation or
reorganization, holders of Old Subordinated Securities (as defined herein) may
recover less, ratably, than creditors in respect of General Obligations and
may recover more, ratably, than the holders of New Subordinated Securities.
   
  Subject to payment in full of all Senior Indebtedness, the holders of
Subordinated Securities will be subrogated to the rights of the holders of
Senior Indebtedness to receive payments or distributions of cash, property or
securities of BANC ONE applicable to Senior Indebtedness. Subject to payment
in full of all General Obligations, the holders of the New Subordinated
Securities will be subrogated to the rights of the creditors in respect of
General Obligations to receive payments or distributions of cash, property or
securities of BANC ONE applicable to such creditors in respect of General
Obligations.     
 
 
                                      17
<PAGE>
 
  Senior Indebtedness is defined in the Subordinated Indenture as the
principal of, premium, if any, and interest on (i) all of BANC ONE's
indebtedness for money borrowed, other than the subordinated securities issued
under the Subordinated Indenture, BANC ONE's 7.25% Subordinated Notes Due
August 1, 2002 (the "August 2002 Notes"), BANC ONE's 8.74% Subordinated Notes
Due September 15, 2003 (the "September 2003 Notes"), BANC ONE's 9.875%
Subordinated Notes Due March 1, 2009 (the "March 2009 Notes"), and BANC ONE's
10.00% Subordinated Notes Due August 15, 2010 (the "August 2010 Notes", and,
together with the August 2002 Notes, the September 2003 Notes and the March
2009 Notes, the "Existing Subordinated Indebtedness"), whether outstanding on
the date of execution of the Subordinated Indenture or thereafter created,
assumed or incurred, except such indebtedness as is by its terms expressly
stated to be not superior in right of payment to the subordinated securities
issued under the Subordinated Indenture or the Existing Subordinated
Indebtedness or to rank pari passu with the subordinated securities issued
under the Subordinated Indenture or the Existing Subordinated Indebtedness
and; (ii) any deferrals, renewals or extensions of any such Senior
Indebtedness. The term "indebtedness for money borrowed" as used in the prior
sentence includes, without limitation, any obligation of, or any obligation
guaranteed by, BANC ONE for the repayment of borrowed money, whether or not
evidenced by bonds, debentures, notes or other written instruments, and any
deferred obligation for the payment of the purchase price of property or
assets. There is no limitation on the issuance of additional Senior
Indebtedness of BANC ONE.
 
  The Existing Subordinated Indebtedness all constitute Old Subordinated
Securities. The Subordinated Securities rank and will rank pari passu with the
Existing Subordinated Indebtedness, subject to the obligations of the holders
of Subordinated Securities (and holders of other New Subordinated Securities)
to pay over any Excess Proceeds to creditors in respect of General
Obligations. Thus, in the event of a distribution of assets of BANC ONE upon
any dissolution, winding up, liquidation or reorganization, the holders of the
New Subordinated Securities (including holders of the Subordinated Securities
offered hereby) may receive less, ratably, than holders of Old Subordinated
Securities.
 
  Unless otherwise specified in the Prospectus Supplement relating to a
particular series of Subordinated Securities offered thereby, General
Obligations means all obligations of BANC ONE to make payment on account of
claims in respect of derivative products such as interest and foreign exchange
rate contracts, commodity contracts and similar arrangements, other than (i)
obligations on account of Senior Indebtedness, (ii) obligations on account of
indebtedness for money borrowed ranking pari passu with or subordinate to the
Subordinated Securities and (iii) obligations which by their terms are
expressly stated not to be superior in right of payment to the Subordinated
Securities or to rank on parity with the Subordinated Securities; provided,
however, that notwithstanding the foregoing, in the event that any rule,
guideline or interpretation promulgated or issued by the Federal Reserve (or
other competent regulatory agency or authority), as from time to time in
effect, establishes or specifies criteria for the inclusion in regulatory
capital of subordinated debt of a bank holding company requiring that such
subordinated debt be subordinated to obligations to creditors in addition to
those set forth above, then the term "General Obligations" shall also include
such additional obligations to creditors, as from time to time in effect
pursuant to such rules, guidelines or interpretations. For purposes of this
definition, "claim" shall have the meaning assigned thereto in Section 101(4)
of the Bankruptcy Code of 1978, as amended to the date of the Subordinated
Indenture.
 
LIMITED RIGHTS OF ACCELERATION
   
  Unless otherwise specified in the Prospectus Supplement relating to any
series of Subordinated Securities, payment of principal of the Subordinated
Securities may be accelerated only in case of the bankruptcy, insolvency or
reorganization of BANC ONE. There is no right of acceleration in the case of a
default in the payment of principal of, premium, if any, or interest on the
Subordinated Securities or the performance of any other covenant of BANC ONE
in the Subordinated Indenture. Payment of principal of the Old Subordinated
Securities may be accelerated in the case of the bankruptcy, insolvency or
reorganization of BANC ONE.

EVENTS OF DEFAULT, DEFAULTS, WAIVERS, ETC.
   
  An Event of Default with respect to Subordinated Securities of any series is
defined in the Subordinated Indenture as certain events involving the
bankruptcy, insolvency or reorganization of BANC ONE and any other Event of
Default provided with respect to Subordinated Securities of that series. A
Default with respect to Subordinated Securities of any series is defined in
the Subordinated Indenture as (i) an Event of Default with respect to such
series, (ii) default in the payment of the principal of or premium, if any, on
any Subordinated Security of such series when due, (iii) default in the
payment of interest upon any Subordinated Security of such series when due and
the continuance of such default for a period of 30 days, (iv) default in the
performance of any other covenant or agreement of BANC ONE in the Subordinated
Indenture with respect to Subordinated Securities of such series and
continuance of such default for 90 days after written notice or (v) any other
Default provided with respect to Subordinated Securities of any series. If an
Event of Default with respect to any series of Subordinated Securities for
which there are Subordinated Securities outstanding under the Subordinated
Indenture occurs and is continuing, either the applicable Trustee or the
holders of not less than 25% in aggregate principal amount of the Subordinated
Securities of such series may declare the principal amount (or if such
Subordinated Securities are Original Issue Discount Securities, such portion
of the principal amount as may be specified in the terms of that series) of
all Subordinated Securities of that series to be immediately due and payable.
The holders of a majority in aggregate principal amount of the Subordinated
Securities of any series outstanding under the Subordinated Indenture may
waive an Event of Default resulting in acceleration of such Subordinated
Securities, but only if all Defaults have been remedied and all payments due
(other than those due as a result of acceleration) have been made. If a
Default occurs and is continuing, the Trustee may in its discretion, and at
the written request of holders of not less than a majority in aggregate
principal amount of the Subordinated Securities of any series outstanding
under the Subordinated Indenture and upon reasonable indemnity against the
costs, expenses and liabilities to be incurred in compliance with such request
and subject to certain other conditions set forth in the Subordinated
Indenture shall, proceed to protect the rights of the holders of all the
Subordinated Securities of such series. Prior to acceleration of maturity of
the Subordinated Securities of any series outstanding under the Subordinated
Indenture, the holders of a majority in aggregate principal amount of such
Subordinated Securities may waive any past default under the Subordinated
Indenture except a default in the payment of principal of, premium, if any, or
interest on the Subordinated Securities of such series.     
 
  The Subordinated Indenture provides that in the event of a Default specified
in clauses (ii) or (iii) of the immediately preceding paragraph in payment of
principal of, premium, if any, or interest on any Subordinated Security of any
series, BANC ONE will, upon demand of the applicable Trustee, pay to it, for
the benefit of the holder of any such Subordinated Security, the whole amount
then due and payable on such Subordinated Security for principal, premium, if
any, and interest. The Subordinated Indenture further provides that if BANC
ONE fails to pay such amount forthwith upon such demand, the applicable
Trustee may, among other things, institute a judicial proceeding for the
collection thereof.
 
  The Subordinated Indenture also provides that notwithstanding any other
provision of the Subordinated Indenture, the holder of any Subordinated
Security of any series shall have the right to institute suit for the
enforcement of any payment of principal of, premium, if any, and interest on
such Subordinated Security on the respective Stated Maturities (as defined in
the Subordinated Indenture) expressed in such Subordinated Security and that
such right shall not be impaired without the consent of such holder.
 
  BANC ONE is required to file annually with the Trustee a written statement
of officers as to the existence or non-existence of defaults under the
Subordinated Indenture or the Subordinated Securities.
 
REGARDING CITIBANK
   
  Citibank will be the Trustee under the Subordinated Indenture. Citibank also
serves as trustee under the indentures with BANC ONE relating to the August
2002 Notes, the September 2003 Notes and the August 2010 Notes. Citibank
provides a $100,000,000 line of credit which partially supports BANC ONE's
commercial paper program. In addition, BANC ONE maintains other banking
relationships with Citibank.

                             PLAN OF DISTRIBUTION
 
  The distribution of the Debt Securities may be effected from time to time in
one or more transactions at a fixed price or prices (which may be changed 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. Each
Prospectus Supplement will describe the method of distribution of the Debt
Securities offered therein.
 
  BANC ONE may sell Debt Securities directly, through agents designated from
time to time, through underwriting syndicates led by one or more managing
underwriters or through one or more underwriters acting alone. Each Prospectus
Supplement will set forth the terms of the Debt Securities to which such
Prospectus Supplement relates, including the name or names of any underwriters
or agents with whom BANC ONE has entered into arrangements with respect to the
sale of such Debt Securities, the public offering or purchase price of such
Debt Securities and the net proceeds to BANC ONE from such sale, any
underwriting discounts and other items constituting underwriters'
compensation, any discounts and commissions allowed or paid to dealers, if
any, any commissions allowed or paid to agents, and the securities exchange or
exchanges, if any, on which such Debt Securities will be listed. Dealer
trading may take place in certain of the Debt Securities, including Debt
Securities not listed on any securities exchange.
 
  Securities may be purchased to be reoffered to the public through
underwriting syndicates led by one or more managing underwriters, or through
one or more underwriters acting alone. The underwriter or underwriters with
respect to each underwritten offering of Debt Securities will be named in the
Prospectus Supplement relating to such offering and, if an underwriting
syndicate is used, the managing underwriter or underwriters will be set forth
on the cover page of such Prospectus Supplement. Unless otherwise set forth in
the applicable Prospectus Supplement, the obligations of the underwriters to
purchase the Debt Securities will be subject to certain conditions precedent
and each of the underwriters with respect to a sale of Debt Securities will be
obligated to purchase all of its Debt Securities if any are purchased. Any
initial public offering price and any discounts or concession allowed or
reallowed or paid to dealers may be changed from time to time.
 
  Debt Securities may be offered and sold by BANC ONE through agents
designated by BANC ONE from time to time. Any agent involved in the offer and
sale of any Debt Securities will be named, and any commissions payable by BANC
ONE to such agent will be set forth, in the Prospectus Supplement relating to
such offering. Unless otherwise indicated in such Prospectus Supplement, any
such agent will be acting on a best efforts basis for the period of its
appointment.
 
  Offers to purchase Debt Securities may be solicited directly by BANC ONE and
sales thereof may be made by BANC ONE directly to institutional investors or
others who may be deemed to be underwriters within the meaning of the
Securities Act with respect to any resale thereof. The terms of any such sales
will be described in the Prospectus Supplement relating thereto. BANC ONE may
also issue contracts under which the counterparty may be required to purchase
Debt Securities. Such contracts would be issued with Debt Securities in
amounts, at prices and on terms to be set in a Prospectus Supplement.
 
  The anticipated place and time of delivery of Debt Securities will be set
forth in the applicable Prospectus Supplement.
 
  If so indicated in the applicable Prospectus Supplement, BANC ONE will
authorize underwriters or agents to solicit offers by certain institutions to
purchase Debt Securities from BANC ONE pursuant to delayed delivery contracts
providing for payment and delivery at a future date. Institutions with which
such contracts may be made include commercial and savings banks, insurance
companies, pension funds, investment companies, educational and charitable
institutions and others, but in all cases such institutions must be approved
by BANC ONE. Unless otherwise set forth in the applicable Prospectus
Supplement, the obligations of any purchaser under any such contract will not
be subject to any conditions except that (i) the purchase of the Debt
Securities shall not at the time of delivery be prohibited under the laws of
the jurisdiction to which such purchaser is subject, and (ii) if the Debt
Securities are also being sold to underwriters acting as principals for their
own account, the underwriters

ITEM 15. INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
  Section 1701.13(E) of the Ohio General Corporation Law sets forth provisions
which define the extent to which a corporation may indemnify directors,
officers and employees. Those provisions have been adopted by the Registrant
in Article V of Registrant's Code of Regulations which provide for the
indemnification or the purchase of insurance for the directors, officers,
employees and agents of the Registrant to afford protection and reimbursement
for such persons acting in their capacities as directors, officers, employees
or agents of the Registrant, provided such person acted in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the Registrant and which he had no reason to believe was
unlawful.

ITEM 17. UNDERTAKINGS
 
  The undersigned Registrant hereby undertakes:
 
  (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement: (i) to include any
prospectus required by Section 10(a)(3) of the Securities Act of 1933;
 
                                     II-1
<PAGE>
 
(ii) to reflect in the prospectus any facts or events arising after the
effective date of the registration statement (or the most recent post-
effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the
registration statement (notwithstanding the foregoing, any increase or
decrease in volume of securities offered (if the total dollar value of
securities offered would not exceed that which was registered) and any
deviation from the low or high end of the estimated maximum offering range may
be reflected in the form of prospectus filed with the Commission pursuant to
Rule 424(b) if, in the aggregate, the changes in volume and price represent no
more than a 20% change in the maximum aggregate offering price set forth in
the "Calculation of Registration Fee" table in the effective registration
statement); and (iii) to include any material information with respect to the
plan of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement.
Provided, however, that (1)(i) and (1)(ii) do not apply if the information
required to be included in a post-effective amendment by those items is
contained in periodic reports filed by the registrant pursuant to Section 13
or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated
by reference to this 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.
 
  (4) 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 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.
 
  (5) 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 provisions described under Item 15 above 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 against the Registrant by such
director, officer or controlling person in connection with the securities
being registered, the Registrant will, unless 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.
 
  (6) To file an application for the purpose of determining the eligibility of
the trustee to act under subsection (a) of Section 310 of the Trust Indenture
Act in accordance with the rules and regulations prescribed by the Commission
under Section 305(b)(2) of the Act.
 
                                  SIGNATURES
   
  Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing this Registration Statement and has duly caused this
Amendment No. 1 to the Registration Statement to be signed on its behalf by
the undersigned, thereunto duly authorized, in the City of Columbus, State of
Ohio, on July 7, 1995.

To the Representatives
  named in Schedule I
  hereto of the Under-

  Schedule II hereto


Dear Sirs:

          BANC ONE CORPORATION, an Ohio corporation (the "Company"), proposes to
sell to the underwriters named in Schedule II hereto (the "Underwriters"), for
whom you (the "Representatives") are acting as representatives, the principal
amount of its securities identified in Schedule I hereto (the "Securities"), to
be issued under an indenture (the "Indenture") dated as of           , 19  ,
between the Company and               , as trustee (the "Trustee").  If the firm
or firms listed in Schedule II hereto include only the firm or firms listed in
Schedule I hereto, then the terms "Underwriters" and "Representatives", as used
herein, shall each be deemed to refer to such firm or firms.

          1.  Representations and Warranties.  The Company represents and 
              -------------------------------                          
warrants to, and agrees with, each Under writer as set forth below in this
Section 1. Certain terms used in this Section 1 are defined in paragraph (d)
hereof.

          (a)  If the offering of the Securities is a Delayed Offering (as
     specified in Schedule I hereto), paragraph (i) below is applicable and, if
     the offering
<PAGE>
 
                                                                               2


     of the Securities is a Non-Delayed Offering (as so specified), paragraph
     (ii) below is applicable.

               (i) The Company meets the requirements for the use of Form S-3
          under the Securities Act of 1933 (the "Act") and has filed with the
          Securities and Exchange Commission (the "Commission") a registration
          statement (the file number of which is set forth in Schedule I hereto)
          on such Form, including a basic prospectus, for registration under the
          Act of the offering and sale of the Securities.  The Company may have
          filed one or more amendments thereto, and may have used a Preliminary
          Final Prospectus, each of which has previously been furnished to you.
          Such registra tion statement, as so amended, has become effec tive.
          The offering of the Securities is a Delayed Offering and, although the
          Basic Prospectus may not include all the information with respect to
          the Securities and the offering thereof required by the Act and the
          rules thereunder to be included in the Final Prospectus, the Basic
          Prospectus includes all such information required by the Act and the
          rules thereunder to be included therein as of the Effective Date.  The
          Company will next file with the Commission pursuant to Rules 415 and
          424(b)(2) or (5) a final supplement to the form of prospectus included
          in such registration statement relating to the Securities and the
          offering thereof.  As filed, such final prospectus supple ment shall
          include all required information with respect to the Securities and
          the offering thereof and, except to the extent the Representatives
          shall agree in writing to a modification, shall be in all substantive
          respects in the form furnished to you prior to the Execution Time or,
          to the extent not completed at the Execution Time, shall contain only
          such specific additional information and other changes (beyond that
          contained in the Basic Prospectus and any Preliminary Final Pro
          spectus) as the Company has advised you, prior to the Execution Time,
          will be included or made therein.  If the Rule 434 Delivery
          Alternative is used, the Company will also file the Rule 434 Term
          Sheet in accordance with Rule 434.  As filed, such Rule 434 Term Sheet
          shall contain all the information required by Rule 434, and except to
          the extent the Representatives shall agree in

          writing to a modification, shall be in all substantive respects in the
          form furnished to you prior to the Execution Time or, to the extent
          not completed at the Execution Time, shall contain only such specific
          additional information and other changes (beyond that contained in the
          latest Preliminary Prospectus) as the Company has advised you, prior
          to the Execution Time, will be included or made therein.  Upon your
          request, but not without your agreement, the Company will also file a
          Rule 462(b) Registration Statement in accordance with Rule 462(b).

              (ii) The Company meets the requirements for the use of Form S-3
          under the Act and has filed with the Commission a registration
          statement (the file number of which is set forth in Schedule I hereto)
          on such Form, including a basic prospec tus, for registration under
          the Act of the offer ing and sale of the Securities.  The Company may
          have filed one or more amendments thereto, including a Preliminary
          Final Prospectus, each of which has previously been furnished to you.
          The Company will next file with the Commission either (x) a final
          prospectus supplement relating to the Securities in accordance with
          Rules 430A and 424(b)(1) or (4), or (y) prior to the effective ness of
          such registration statement, an amendment to such registration
          statement, including the form of final prospectus supplement.  In the
          case of clause (x), the Company has included in such registration
          statement, as amended at the Effec tive Date, all information (other
          than Rule 430A Information) required by the Act and the rules
          thereunder to be included in the Final Prospectus with respect to the
          Securities and the offering thereof.  As filed, such final prospectus
          supple ment or such amendment and form of final prospec tus supplement
          shall contain all Rule 430A Infor mation, together with all other such
          required information, with respect to the Securities and the offering
          thereof and, except to the extent the Representatives shall agree in
          writing to a modification, shall be in all substantive respects in the
          form furnished to you prior to the Execu tion Time or, to the extent
          not completed at the Execution Time, shall contain only such specific
          additional information and other changes (beyond

          that contained in the Basic Prospectus and any Preliminary Final
          Prospectus) as the Company has advised you, prior to the Execution
          Time, will be included or made therein.  If the Rule 434 Delivery
          Alternative is used, the Company will also file the Rule 434 Term
          Sheet in accordance with Rule 434.  As filed, such Rule 434 Term Sheet
          shall contain all the information required by Rule 434, and except to
          the extent the Representatives shall agree in writing to a
          modification, shall be in all substantive respects in the form

          completed at the Execution Time, shall contain only such specific
          additional information and other changes (beyond that contained in the
          latest Preliminary Prospectus) as the Company has advised you, prior
          to the Execution Time, will be included or made therein.  Upon your
          request, but not without your agreement, the Company will also file a

              ------------------                                            
reliance upon the representations and war ranties herein set forth, the Company
agrees to sell to each Underwriter, and each Underwriter agrees, severally and
not jointly, to purchase from the Company, at the purchase price set forth in
Schedule I hereto the principal amount of the Securities set forth opposite such
Underwriter's name in Schedule II hereto, except that, if Schedule I hereto
provides for the sale of Securities pursuant to delayed delivery arrangements,
the respective principal amounts of Securities to be purchased by the
Underwriters shall be as set forth in Schedule II hereto less the respective
amounts of Contract Securities determined as provided below.  Securities to be
purchased by the Underwriters are herein sometimes called the "Underwriters'
Securities" and Secur ities to be purchased pursuant to Delayed Delivery

<PAGE>
 
                                                                               8

to solicit offers to purchase Secu rities from the Company pursuant to delayed
delivery con tracts ("Delayed Delivery Contracts"), substantially in the form of
Schedule III hereto but with such changes therein as the Company may authorize
or approve.  The Underwriters will endeavor to make such arrangements and, as
compensation therefor, the Company will pay to the Representatives, for the
account of the Underwriters, on the Closing Date, the percentage set forth in
Schedule I hereto of the principal amount of the Securities for which Delayed
Delivery Con tracts are made.  Delayed Delivery Contracts are to be with
institutional investors, including commercial and savings banks, insurance
companies, pension funds, investment companies and educational and charitable
institutions.  The Company will enter into Delayed Delivery Contracts in all
cases where sales of Contract Securities arranged by the Underwriters have been

such Delayed Delivery Contract must be for not less than the minimum principal
amount set forth in Schedule I hereto and the aggregate principal amount of
Contract Securities may not exceed the maximum aggregate principal amount set
forth in Schedule I hereto.  The Underwriters will not have any responsibility
in respect of the validity or performance of Delayed Delivery Contracts.  The
principal amount of Secu rities to be purchased by each Underwriter as set forth
in Schedule II hereto shall be reduced by an amount which shall bear the same
proportion to the total principal amount of Contract Securities as the principal
amount of Securities set forth opposite the name of such Underwriter bears to
the aggregate principal amount set forth in Schedule II hereto, except to the
extent that you determine that such reduction shall be otherwise than in such
proportion and so advise the Company in writing; provided, however, that the
                                                 --------  -------          
total prin cipal amount of Securities to be purchased by all Under writers shall
be the aggregate principal amount set forth in Schedule II hereto less the
aggregate principal amount of Contract Securities.

Delivery of the Underwriters' Securities shall be made to the Representatives
for the respective accounts of the several Underwriters against payment by the
several Underwriters through the Representatives of the purchase price thereof
to or upon the order of the Company by [wire transfer or check in Federal (same
day) funds] [certified or official bank check or checks drawn on or by a New
York Clearing House bank and payable in next day funds].  Delivery of the
Underwriters' Securities shall be made at such location as the Representatives
shall reasonably designate at least one business day in advance of the Closing
Date and payment for the Securities shall be made at the office specified in
Schedule I hereto.  Certificates for the Underwriters' Securities shall be

          4.  Agreements.  The Company agrees with the several Underwriters
              -----------                                                  
that:

          (a)  The Company will use its best efforts to cause the Registration
     Statement, if not effective at the Execution Time, and any amendment
     thereto, to become effective.  Prior to the termination of the offering of
     the Securities, the Company will not file any amendment of the Registration
     Statement or supple ment (including the Final Prospectus or any Preliminary
     Final Prospectus) to the Basic Prospectus or any Rule 462(b) Registration
     Statement unless the Company has furnished you a copy for your review prior
     to filing and will not file any such proposed amendment or supplement or
     Rule 462(b) Registration Statement to which you reasonably object.  Subject
     to the foregoing sentence, the Company will cause the Final Prospectus,
     properly completed, and any supplement thereto to be filed with the
     Commission pursuant to the applicable paragraph of Rule 424(b) within the
     time period prescribed and will provide evidence satisfactory to the
     Representatives of such timely filing.  If the Rule 434 Delivery
     Alternative is used, the Company will also cause the rule 434 Term Sheet,
     properly completed, to
<PAGE>
 
                                                                              10

     be filed with the Commission pursuant to Rule 434 within the time period
     prescribed and will provide evidence satisfactory to the Representatives of
     such timely filing.  Upon your request, the Company will cause the Rule
     462(b) Registration Statement, properly completed, to be filed with the
     Commission pursuant to Rule 462(b) and will provide evidence satisfactory
     to the representatives of such filing.  The Company will promptly advise
     the Representatives (i) when the Registration Statement, if not effective
     at the Execution Time, and any amendment thereto, shall have become
     effective, (ii) when the Final Prospectus, any supplement thereto, any Rule
     434 Term Sheet or any Rule 462(b) Registration Statement shall have been
     filed with the Commission pursuant to Rule 424(b), (iii) when, prior to
     termination of the offering of the Securities, any amendment to the
     Registration Statement shall have been filed or become effective, (iv) of
     any request by the Commission for any amendment of the Registration
     Statement or supplement to the Final Prospectus or for any additional
     information, (v) of the issuance by the Commission of any stop order
     suspending the effectiveness of the Registration Statement or the
     institution or threatening of any proceeding for that purpose and (vi) of
     the receipt by the Company of any notification with respect to the
     suspension of the qualification of the Securities for sale in any
     jurisdiction or the initiation or threatening of any proceeding for such
     purpose.  The Company will use its best efforts to prevent the issuance of
     any such stop order and, if issued, to obtain as soon as possible the
     withdrawal thereof.

          (b)  If, at any time when a prospectus relating to the Securities is
     required to be delivered under the Act, any event occurs as a result of
     which the Final Prospectus as then supplemented would include any untrue
     statement of a material fact or omit to state any material fact necessary
     to make the statements therein in the light of the circumstances under
     which they were made not misleading, or if it shall be neces sary to amend
     the Registration Statement or supplement the Final Prospectus to comply
     with the Act or the Exchange Act or the respective rules thereunder, the
     Company promptly will (i) prepare and file with the Commission, subject to
     the second sentence of paragraph (a) of this Section 4, an amendment or
     supplement which will correct such statement or omission or effect such
<PAGE>
 
                                                                              11

     compliance and (ii) supply any supplemented Prospectus to you in such
     quantities as you may reasonably request.

          (c)  As soon as practicable, the Company will make generally available
     to its security holders and to the Representatives an earnings statement or
     statements of the Company and its subsidiaries which will satisfy the
     provisions of Section 11(a) of the Act and Rule 158 under the Act.

          (d)  The Company will furnish to the Representa tives and counsel for
     the Underwriters, without charge, copies of the Registration Statement
     (including exhib its thereto) and, so long as delivery of a prospectus by
     an Underwriter or dealer may be required by the Act, as many copies of any
     Preliminary Final Prospectus and the Final Prospectus and any supplement
     thereto as the Representatives may reasonably request.  The Company will
     pay the expenses of printing or other production of all documents relating
     to the offering.

          (e)  The Company will arrange for the qualifica tion of the Securities
     for sale under the laws of such jurisdictions as the Representatives may
     designate, will maintain such qualifications in effect so long as required
     for the distribution of the Securities and will arrange for the
     determination of the legality of the Securities for purchase by
     institutional investors, provided that in connection therewith the Company
     will not be required to qualify as a foreign corporation or to file a
     general consent to service of process in any jurisdiction.

          (f)  Until the business date set forth on Sched ule I hereto, the
     Company will not, without the consent of the Representatives, offer, sell
     or contract to sell, or otherwise dispose of, directly or indirectly, or
     announce the offering of, any debt securities issued or guaranteed by the
     Company (other than the Securities or any commercial paper issued by the
     Company).

     compliance with all provisions of Section 1 of Laws of Florida, Chapter 92-
     198, An Act Relating to Disclosure of Doing Business with Cuba, and the

     reported in the Prospectus, if any, concerning the Company's business with
     Cuba or with any person or affiliate located in Cuba changes in any
     material way, the Company will provide the Department notice of such
     business or change, as appropriate, in a form acceptable to the Department.

          of equity (whether in a proceeding at law or in equity)); and the
          Securities have been duly authorized by the Company and, when executed
          and authenticated in accordance with the provisions of the Indenture
          and delivered to and paid for by the Underwriters pursuant to this
          Agreement, in the case of the Underwriters' Securities, or by the
          purchasers thereof pursuant to Delayed Delivery Contracts, in the case
          of any Contract Securities, will constitute legal, valid and binding
          obligations of the Company entitled to the benefits of the Indenture
          (subject, as to enforceability, to applicable bankruptcy,
          reorganization, insolvency, fraudulent conveyance, moratorium or other
          laws affecting creditors' rights generally from time to time in effect
          and subject to general principles of equity (whether in a proceeding
          at law or in equity));

              (vi) to the best knowledge of such counsel, there is no pending or
          threatened action, suit or proceeding before any court or governmental
          agency, authority or body or any arbitrator involving the Company or
          any of its subsidiaries, of a character required to be disclosed in
          the Registration Statement which is not adequately disclosed in the
          Final Prospectus, and there is no franchise, contract or other
          document of a char acter required to be described in the Registration
          Statement or Final Prospectus, or to be filed as an exhibit, which is
          not described or filed as required; and the statements included or
          incor porated in the Final Prospectus describing any legal proceedings
          or material contracts or agree ments relating to the Company fairly
          summarize such matters;

             (vii) such counsel has been advised by the Commission's staff that
          the Registration Statement has become effective under the Act; any
          required filing of the Basic Prospectus, any Preliminary Final
          Prospectus and the Final Prospectus, and any supplements thereto,
          pursuant to Rule 424(b) has been made in the manner and within the
          time period required by Rule 424(b)or if the Rule 434 Delivery
          Alternative was used, the required filing of the Rule 434 Term Sheet
          has been made in the manner and time period required by Rule 434; to
          the best

          knowledge of such counsel, no stop order suspending the effectiveness
          of the Registration Statement has been issued, no proceedings for that
          purpose have been instituted or threatened, and the Registration
          Statement and the Final Pros pectus (other than the financial
          statements and other financial and statistical information contained
          therein as to which such counsel need express no opinion) comply as to
          form in all material respects with the applicable requirements of the
          Act, the Exchange Act and the Trust Indenture Act and the respective
          rules thereunder; and such counsel has no reason to believe that at
          the Effective Date the Registration Statement (other than the
          financial statements and other financial and statistical information
          contained therein as to which such counsel need express no opinion)
          contained any untrue statement of a material fact or omitted to state
          any material fact required to be stated therein or necessary to make
          the statements therein not misleading or that the Final Prospectus
          (other than the financial statements and other financial and
          statistical information contained therein as to which such counsel
          need express no opinion) includes any untrue statement of a material
          fact or omits to state a material fact necessary to make the state
          ments therein, in the light of the circumstances under which they were
          made, not misleading;

            (viii) this Agreement and any Delayed Delivery Contracts have been
          duly authorized, executed and delivered by the Company;

              (ix) no consent, approval, authorization or order of any Federal
          or Ohio court or governmental agency or body is required for the
          consummation of the transactions contemplated herein or in any Delayed
          Delivery Contracts, except such as have been obtained under the Act
          and the Trust Indenture Act and such as may be required under the blue
          sky laws of any jurisdiction in connection with the purchase and
          distribution of the Securities by the Underwriters and such other
          approvals (specified in such opinion) as have been obtained;

                                                                              17

               (x) neither the execution and delivery by the Company of the
          Indenture, the issue and sale of the Securities, nor the consummation
          by the Company of any other of the transactions herein contemplated
          nor the fulfillment by the Company of the terms hereof or of any
          Delayed Delivery Contracts will result in a breach or violation of, or
          constitute a default under (A) the articles of incorporation or code
          of regulations of the Company, (B) the terms of any indenture or other
          material agreement or instrument known to such counsel and to which
          the Company or any of its subsidiaries is a party or bound, (C) any
          judgment, order or decree known to such counsel to be specifically
          applicable to the Company or any of its subsidiaries of any Federal or
          Ohio court, regulatory body, administrative agency, governmental body
          or arbitrator having jurisdiction over the Company or any of its
          subsidiaries or (D) any provision of Federal or Ohio statute or
          governmental regulation applicable to the Company; and

              (xi) no holders of securities of the Company have rights to the
          registration of such securities under the Registration Statement.

     In rendering such opinion, such counsel may rely (A) as to matters
     involving the application of laws of any jurisdiction other than the State
     of Ohio or the United States, to the extent deemed proper and specified in
     such opinion, upon the opinion of other counsel of good standing believed
     to be reliable and who are satisfactory to counsel for the Underwriters and
     (B) as to matters of fact, to the extent deemed proper, on certificates of
     responsible officers of the Company and public officials.  References to
     the Final Prospectus in this paragraph (b) include any supplements thereto
     at the Closing Date.

          (c)  The Representatives shall have received from Cravath, Swaine &
     Moore, counsel for the Underwriters, such opinion or opinions, dated the
     Closing Date, with respect to the issuance and sale of the Securities, the
     Indenture, any Delayed Delivery Contracts, the Regis tration Statement, the
     Final Prospectus (together with any supplement thereto) and other related
     matters as the Representatives may reasonably require, and the

                                                                              18

     Company shall have furnished to such counsel such documents as they request
     for the purpose of enabling them to pass upon such matters.

          (d)  The Company shall have furnished to the Representatives a
     certificate of the Company, signed by the Chairman of the Board, the
     President or an Executive Vice President and the principal financial or
     accounting officer or Treasurer of the Company, dated the Closing Date, to
     the effect that the signers of such certificate have carefully examined the
     Registration Statement, the Final Prospectus, any supplement to the Final
     Prospectus and this Agreement and that:

               (i) the representations and warranties of the Company in this
          Agreement are true and correct in all material respects on and as of
          the Closing Date with the same effect as if made on the Closing Date
          and the Company has complied with all the agreements and satisfied all
          the conditions on its part to be performed or satisfied at or prior to
          the Closing Date;

              (ii) no stop order suspending the effective ness of the
          Registration Statement has been issued and no proceedings for that
          purpose have been instituted or, to the Company's knowledge, threat
          ened; and

             (iii) since the date of the most recent finan cial statements
          included in the Final Prospectus (exclusive of any supplement
          thereto), there has been no material adverse change in the condition
          (financial or other), earnings, business or properties of the Company
          and its subsidiaries, whether or not arising from transactions in the
          ordinary course of business, except as set forth in or contemplated in
          the Final Prospectus (exclu sive of any supplement thereto).

          (e)  At the Closing Date, Coopers & Lybrand L.L.P. shall have
     furnished to the Representatives a letter or letters (which may refer to
     letters previously delivered to one or more of the Representatives), dated
     as of the Closing Date, in form and substance satis factory to the
     Representatives.
<PAGE>
 
                                                                              19

               In addition, except as provided in Schedule I hereto, at the
     Execution Time, Coopers & Lybrand L.L.P. shall have furnished to the
     Representatives a letter or letters, dated as of the Execution Time, in
     form and substance satisfactory to the Representatives, to the effect set
     forth above.

          (f)  Subsequent to the Execution Time or, if earlier, the dates as of
     which information is given in the Registration Statement (exclusive of any
     amendment thereof) and the Final Prospectus (exclusive of any supplement
     thereto), there shall not have been (i) any change or decrease specified in
     the letter or letters referred to in paragraph (e) of this Section 5 or
     (ii) any change, or any development involving a prospective change, in or
     affecting the business or properties of the Company and its subsidiaries
     the effect of which, in any case referred to in clause (i) or (ii) above,
     is, in the judgment of the Representa tives, so material and adverse as to
     make it impractical to proceed with the offering or delivery of the
     Securities as contemplated by the Registration Statement (exclusive of any
     amendment thereof) and the Final Prospectus (exclusive of any supplement
     thereto).

          (g)  Subsequent to the Execution Time, there shall not have been any
     decrease in the rating of any of the Company's debt securities by any
     "nationally recognized statistical rating organization" (as defined for
     purpose of Rule 436(g) under the Act) or any notice given of any intended
     or potential decrease in any such rating or of a possible change in any
     such rating that does not indicate the direction of the possible change.

          (h)  Prior to the Closing Date, the Company shall have furnished to
     the Representatives such further information, certificates and documents as
     the Repre sentatives may reasonably request.

          (i)  The Company shall have accepted Delayed Delivery Contracts in any
     case where sales of Contract Securities arranged by the Underwriters have
     been approved by the Company.

          If any of the conditions specified in this Sec tion 5 shall not have
been fulfilled in all material re spects when and as provided in this Agreement,
or if any of
<PAGE>
 
                                                                              20

the opinions and certificates mentioned above or elsewhere in this Agreement
shall not be in all material respects reasonably satisfactory in form and
substance to the Repre sentatives and counsel for the Underwriters, this
Agreement and all obligations of the Underwriters hereunder may be canceled at,
or at any time prior to, the Closing Date by the Representatives.  Notice of
such cancellation shall be given to the Company in writing or by telephone or
telegraph confirmed in writing.

          The documents required to be delivered by this Section 5 shall be
delivered at the office of Cravath, Swaine & Moore, counsel for the
Underwriters, at Worldwide Plaza, 825 Eighth Avenue, New York, New York, on the
Closing Date.

          6.  Reimbursement of Underwriters' Expenses.  If the sale of the
              ----------------------------------------                    
Securities provided for herein is not con summated because any condition to the
obligations of the Underwriters set forth in Section 5 hereof is not satisfied,
because of any termination pursuant to Section 9 hereof or because of any
refusal, inability or failure on the part of the Company to perform any
agreement herein or comply with any provision hereof other than by reason of a
default by any of the Underwriters, the Company will reimburse the Underwriters
severally upon demand for all out-of-pocket expenses (including reasonable fees
and disbursements of counsel) that shall have been incurred by them in
connection with the proposed purchase and sale of the Securities.

          7.  Indemnification and Contribution.  (a)  The Company agrees to
              ---------------------------------                            
indemnify and hold harmless each Under writer, the directors, officers,
employees and agents of each Underwriter and each person who controls any
Underwrit er within the meaning of either the Act or the Exchange Act against
any and all losses, claims, damages or liabilities, joint or several, to which
they or any of them may become subject under the Act, the Exchange Act or other
Federal or state statutory law or regulation, at common law or other wise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in the registration statement for the
registration of the Securities as originally filed or in any amendment thereof,
or in the Basic Prospectus, any Preliminary Final Prospectus or the Final
Prospectus, or in any amendment thereof or supplement thereto, or arise out of
or are based upon the omission or alleged omission to state
<PAGE>
 
                                                                              21

therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and agrees to reimburse each such indemnified
party, as in curred, for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company will not be liable in
                     --------  -------                                        
any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon any such untrue statement or alleged untrue
statement or omission or alleged omission made therein in reliance upon and in
conformity with written information furnished to the Company by or on behalf of
any Underwriter through the Representatives specifically for inclusion therein.
This indemnity agree ment will be in addition to any liability which the Company
may otherwise have.

          (b)  Each Underwriter severally agrees to indem nify and hold harmless
the Company, the directors, officers, employees and agents of the Company, and
each person who controls the Company within the meaning of either the Act or the
Exchange Act, to the same extent as the foregoing indemnity from the Company to
each Underwriter, but only with reference to written information relating to
such Underwriter furnished to the Company by or on behalf of such Underwriter
through the Representatives specifically for inclusion in the documents referred
to in the foregoing indemnity.  This indemnity agreement will be in addition to
any liability which any Underwriter may otherwise have.  The Company
acknowledges that the statements set forth in [the last paragraph of the cover
page, under the heading "Underwriting" or "Plan of Distribution" and, if
Schedule I hereto provides for sales of Securities pursuant to delayed delivery
arrangements, in the last sentence under the heading "Delayed Delivery
Arrangements"] in any Preliminary Final Prospectus or the Final Prospectus
constitute the only information furnished in writing by or on behalf of the
several Underwriters for inclusion in the documents referred to in the foregoing
indemnity, and you, as the Representa tives, confirm that such statements are
correct.

          (c)  Promptly after receipt by an indemnified party under this Section
7 of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 7, notify the indemnifying party in writ ing of the commencement
thereof; but the failure so to notify the indemnifying party (i) will not
relieve it from
<PAGE>
 
                                                                              22

liability under paragraph (a) or (b) above unless and to the extent it did not
otherwise learn of such action and such failure results in the forfeiture by the
indemnifying party of substantial rights and defenses and (ii) will not, in any
event, relieve the indemnifying party from any obligations to any indemnified
party other than the indemnification obligation provided in paragraph (a) or (b)
above.  The indemnifying party shall be entitled to appoint counsel of the
indemnifying party's choice at the indemnifying party's expense to represent the
indemnified party in any action for which indemnification is sought (in which
case the indemni fying party shall not thereafter be responsible for the fees
and expenses of any separate counsel retained by the indem nified party or
parties except as set forth below); provided, however, that such counsel shall
                                    --------  -------                         
be reasonably satisfactory to the indemnified party.  Notwithstanding the
indemnifying party's election to appoint counsel to repre sent the indemnified
party in an action, the indemnified party shall have the right to employ
separate counsel (including local counsel), and the indemnifying party shall
bear the reasonable fees, costs and expenses of such separate counsel if (i) the
use of counsel chosen by the indemnifying party to represent the indemnified
party would present such counsel with a conflict of interest, (ii) the actual or
potential defendants in, or targets of, any such action include both the
indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that there may be legal defenses available to it
and/or other indemnified parties which are different from or additional to those
available to the indemnifying party, (iii) the indemnifying party shall not have
employed counsel reasonably satisfactory to the indemnified party to represent
the indemnified party within a reasonable time after notice of the institution
of such action or (iv) the indemnifying party shall authorize the indemnified
party to employ separate counsel at the expense of the indemnifying party;
provided, however, that in no event shall the indemnifying party be liable for
- --------  -------                                                             
the expenses of more than one separate counsel (plus any local counsel)
representing the indemnified parties who are parties to such action.  An
indemnifying party will not, without the prior written consent of the
indemnified par ties, settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnifica tion or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or
<PAGE>
 
                                                                              23

consent includes an unconditional release of each indemni fied party from all
liability arising out of such claim, action, suit or proceeding.

          (d)  In the event that the indemnity provided in paragraph (a) or (b)
of this Section 7 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and the Underwriters agree to
contribute to the aggregate losses, claims, damages and liabilities (including
legal or other expenses reasonably incurred in connection with investigating or
defending same) (collectively "Losses") to which the Company and one or more of
the Underwriters may be subject in such proportion as is appropriate to reflect
the relative benefits received by the Company and by the Underwriters from the
offering of the Securities; provided, however, that in no case shall any
                            --------  -------                           
Underwriter (except as may be provided in any agreement among underwriters
relating to the offering of the Securi ties) be responsible for any amount in
excess of the under writing discount or commission applicable to the Securities
purchased by such Underwriter hereunder.  If the allocation provided by the
immediately preceding sentence is unavail able for any reason, the Company and
the Underwriters shall contribute in such proportion as is appropriate to
reflect not only such relative benefits but also the relative fault of the
Company and of the Underwriters in connection with the statements or omissions
which resulted in such Losses as well as any other relevant equitable
considerations.  Benefits received by the Company shall be deemed to be equal to
the total net proceeds from the offering (before deduct ing expenses), and
benefits received by the Underwriters shall be deemed to be equal to the total
underwriting discounts and commissions, in each case as set forth on the cover
page of the Final Prospectus.  Relative fault shall be determined by reference
to, among other things, whether any alleged untrue statement or omission relates
to information provided by the Company or the Underwriters and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such alleged untrue statement or omission.  The Company and the
Underwriters agree that it would not be just and equitable if contri bution were
determined by pro rata allocation or any other method of allocation which does
not take account of the equitable considerations referred to above.
Notwithstanding the provisions of this paragraph (d), no person guilty of
fraudulent misrepresentation (within the meaning of Sec tion 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent
<PAGE>
 
                                                                              24

misrepresentation.  For purposes of this Section 7, each person who controls an
Underwriter within the meaning of either the Act or the Exchange Act and each
director, officer, employee and agent of an Underwriter shall have the same
rights to contribution as such Underwriter, and each person who controls the
Company within the meaning of either the Act or the Exchange Act, and each
director, officer, employee or agent of the Company shall have the same rights
to contribution as the Company, subject in each case to the applicable terms and
conditions of this paragraph (d).

          8.  Default by an Underwriter.  If any one or more Underwriters shall
              --------------------------                                       
fail to purchase and pay for any of the Securities agreed to be purchased by
such Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Underwriters shall be obligated severally to take up
and pay for (in the respective proportions which the amount of Securities set
forth opposite their names in Schedule II hereto bears to the aggregate amount
of Securities set forth opposite the names of all the remaining Underwriters)
the Securities which the defaulting Underwriter or Underwriters agreed but
failed to purchase; provided, however, that in the event that the aggregate
                    --------  -------                                      
amount of Securities which the defaulting Underwriter or Underwriters agreed but
failed to purchase shall exceed 10% of the aggregate amount of Securities set
forth in Schedule II hereto, the remaining Underwriters shall have the right to
purchase all, but shall not be under any obligation to purchase any, of the
Securities, and if such nondefaulting Underwriters do not purchase all the
Securities, this Agreement will terminate without liability to any nondefaulting
Underwriter or the Company.  In the event of a default by any Underwriter as set
forth in this Section 8, the Closing Date shall be postponed for such period,
not exceeding seven days, as the Representatives shall determine in order that
the required changes in the Registration Statement and the Final Prospectus or
in any other documents or arrangements may be effected.  Nothing contained in
this Agreement shall relieve any defaulting Underwriter of its liability, if
any, to the Company and any nondefaulting Underwriter for damages occasioned by
its default hereunder.

          9.  Termination.  This Agreement shall be subject to termination in
              ------------                                                   
the absolute discretion of the Represen atatives, by notice given to the Company
prior to delivery of and payment for the Securities, if prior to such time

                                                                              25

(i) trading in the Company's Common Stock shall have been suspended by the
Commission or the New York Stock Exchange or trading in securities generally on
the New York Stock Exchange shall have been suspended or limited or minimum
prices shall have been established on such Exchange, (ii) a banking moratorium
shall have been declared either by Federal or New York, Ohio or Texas State
authorities or (iii) there shall have occurred any outbreak or material
escalation of hostilities, declaration by the United States of a national
emergency or war or other calamity or crisis the effect of which on financial
markets is such as to make it, in the judgment of the Representatives,
impracticable to proceed with the offering or delivery of the Securities as

Dear Sirs:

     The undersigned hereby agrees to purchase from           Corporation (the 
"Company"), and the Company agrees to sell to the undersigned, on         19  , 
(the "Delivery Date"), $      principal amount of the Company's            (the 
"Securities") offered by the Company's Prospectus dated        , 19  , and 
related Prospectus Supplement dated        , 19  , receipt of a copy of which 
is hereby acknowledged, at a purchase price of   % of the principal amount 
thereof, plus [accrued interest] [amortization of original issue discount], if 
any, thereon from        , 19  , to the date of payment and delivery, and on 
the further terms and conditions set forth in this contract.

     Payment for the Securities to be purchased by the undersigned shall be made
on or before 11:00 AM, New York City time, on the Delivery Date to or upon the
order of the Company in New York Clearing House (next day) funds, at your office
or at such other place as shall be agreed between the Company and the
undersigned, upon delivery to the undersigned of the Securities in definitive
fully registered form and in such authorized denominations and registered in
such names as the undersigned may request by written or telegraphic
communication addressed to the Company not less than five full business days
prior to the Delivery Date. If no request is received, the Securities will be
registered in the name of the undersigned and issued in a denomination equal to
the aggregate principal amount of Securities to be purchased by the undersigned
on the Delivery Date.

<PAGE>
 
      The obligation of the undersigned to take delivery of and make payment for
Securities on the Delivery Date, and the obligation of the Company to sell and 
deliver Securities on the Delivery Date, shall be subject to the conditions (and
neither party shall incur any liability by reason of the failure thereof) that 
(1) the purchase of Securities to be made by the undersigned, which purchase the
undersigned represents is not prohibited on the date hereof, shall not on the 
Delivery Date be prohibited under the laws of the jurisdiction to which the 
undersigned is subject, and (2) the Company, on or before the Delivery Date, 
shall have sold to certain underwriters (the "Underwriters") such principal 
amount of the Securities as is to be sold to them pursuant to the Underwriting 
Agreement referred to in the Prospectus and Prospectus Supplement mentioned 
above. Promptly after completion of such sale to the Underwriters, the Company 
will mail or deliver to the undersigned at its address set forth below notice 
to such effect, accompanied by a copy of the opinion of counsel for the Company
delivered to the Underwriters in connection therewith. The obligation of the
undersigned to take delivery of and make payment for the Securities, and the
obligation of the Company to cause the Securities to be sold and delivered,
shall not be affected by the failure of any purchaser to take delivery of and
make payment for the Securities pursuant to other contracts similar to this
contract.

     This contract will inure to the benefit of and be binding upon the parties 
hereto and their respective successors, but will not be assignable by either 
party hereto without the written consent of the other.

     It is understood that acceptance of this contract and other similar 
contracts is in the Company's sole discretion and, without limiting the 
foregoing, need not be on a first come, first served basis. If this contract is 
acceptable to the Company, it is required that the Company sign the form of 
acceptance below and mail or deliver one of the counterparts hereof to the 
undersigned at its address set forth below. This will become a binding contract 
between the Company and the undersigned, as of the date
<PAGE>
 
first above written, when such counterpart is so mailed or delivered.

     This agreement shall be governed by and construed in accordance with the 
laws of the State of New York.


                                        Very truly yours,

                         ---------------------------------------             
where several matters are required to be certified by, or covered by an opinion
of, any specified Person, it is not necessary that all such matters be certified
by, or covered by the opinion of, only one such Person, or that they be so
certified or covered by only one document, but one such Person may certify or
give an opinion with respect to some matters and one or more other such Persons
as to other matters, and any such Person may certify or give an opinion as to
such matters in one or several documents.

          Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous.  Any such certificate or Opinion of Counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with respect to such
matters are erroneous.

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

          SECTION 1.04.  Acts of Holders.  (i)  Any request, demand,
                         ----------------                           
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Holders or Holders of any series may be
embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Holders in person or by an agent duly appointed in writing.
If Securities of a series are issuable in whole or in part as Bearer Securities,
any request, demand, authorization, direction, notice, consent,
<PAGE>
 
                                                                              13

waiver or other action provided by this Indenture to be given or taken by
Holders may, alternatively, be embodied in and evidenced by the record of
Holders of Securities voting in favor thereof, either in person or by proxies
duly appointed in writing, at any meeting of Holders of Securities duly called
and held in accordance with the provisions of Article Fifteen, or a combination
of such instruments and any such record.  Except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
or record or both are delivered to the Trustee, and, where it is hereby
expressly required, to the 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 the holding by any
Person of a Security, shall be sufficient for any purpose of this Indenture and
(subject to Section 8.01) 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 15.06.

          (ii) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by the certificate of any notary public or other officer authorized
by law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof.  Where
such execution is by or on behalf of any legal entity other than an individual,
such certificate or affidavit shall also constitute proof of the authority of
the Person executing the same.  The fact and date of the execution of any such
instrument or writing, or the authority of the Person executing the same, may
also be proved in any other manner which the Trustee deems sufficient.

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

          (iv) 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, as
depositary, by any trust company, bank or other depositary, wherever situated,
if such certificate shall be deemed by
<PAGE>
 
                                                                              14

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, or (2) such Bearer Security is produced to
the Trustee by some other Person, or (3) such Bearer Security is surrendered in
exchange for a Registered Security, or (4) such Bearer Security is no longer
Outstanding.

          (v) The fact and date of execution of any such instrument or writing,
the authority of the Person executing the same and the principal amount and
serial numbers of Bearer Securities held by the Person so executing such
instrument or writing and the date of holding the same may also be proved in any
other manner which the Trustee deems sufficient; and the Trustee may in any
instance require further proof with respect to any of the matters referred to in
this Section.

         (vi) Any request, demand, authorization, direction, notice, consent,
waiver or other action by the Holder of any Security shall bind every future
Holder of the same Security and the Holder of every Security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof, in
respect of any action taken, suffered or omitted by the Trustee or the Company
in reliance thereon, whether or not notation of such action is made upon such
Security.

        (vii) For purposes of determining the principal amount of Outstanding
Securities of any series the Holders of which are required, requested or
permitted to give any request, demand, authorization, direction, notice,
consent, waiver or take any other Act under the Indenture, each Security
denominated in a Foreign Currency or composite currency shall be deemed to have
the principal amount determined by the Exchange Rate Agent by converting the
principal amount of such Security in the currency in which such Security is
denominated into Dollars at the Exchange Rate as of the date such Act is
delivered to the Trustee and, where it is hereby expressly required, to the
Company, by Holders of the required aggregate principal amount of the
<PAGE>
 
                                                                              15

Outstanding Securities of such series (or, if there is no such rate on such
date, such rate on the date determined as specified as contemplated in Section
3.01).

       (viii) The Company may, in the circumstances permitted by the Trust
Indenture Act, set a record date for purposes of determining the identity of
Holders of Securities of any series entitled to give any request, demand,
authorization, direction, notice, consent, waiver or take any other Act, or to
vote or consent to any action by vote or consent authorized or permitted to be
given or taken by Holders of Securities of such series.  If not set by the
Company prior to the first solicitation of a Holder of Securities of such Series
made by any Person in respect of any such action, or in the case of any such
vote, prior to such vote, such record date shall be the later of 30 days prior
to the first solicitation of such consent or the date of the most recent list of
Holders of such Securities furnished to the Trustee pursuant to Section 6.01
prior to such solicitation.

         (ix) Without limiting the foregoing, a Holder entitled hereunder to
take any action hereunder with regard to any particular Security may do so with
regard to all or any part of the principal amount of such Security or by one or
more duly appointed agents, each of which may do so pursuant to such appointment
with regard to all or any part of such principal amount.  Any notice given or
action taken by a Holder or its agents with regard to different parts of such
principal amount pursuant to this paragraph shall have the same effect as if
given or taken by separate Holders of each such different part.

          (x) Without limiting the generality of the foregoing, unless
otherwise specified pursuant to Section 3.01 or pursuant to one or more
indentures supplemental hereto, a Holder, including a Depositary that is the
Holder of a Global Security, may make, give or take, by a proxy or proxies duly
appointed in writing, any request, demand, authorization, direction, notice,
consent, waiver or other action provided in this Indenture to be made, given or
taken by Holders, and a Depositary that is the Holder of a Global Security may
provide its proxy or proxies to the beneficial owners of interests in any such
Global Security through such Depositary's standing instructions and customary
practices.

                                                                              16

         (xi) The Company may fix a record date for the purpose of determining
the Persons who are beneficial owners of interests in any Global Security held
by a Depositary entitled under the procedures of such Depositary to make, give
or take, by a proxy or proxies duly appointed in writing, any request, demand,
authorization, direction, notice, consent, waiver or other action provided in
this Indenture to be made, given or taken by Holders.  If such a record date is
fixed, the Holders on such record date or their duly appointed proxy or proxies,
and only such Persons, shall be entitled to make, give or take such request,
demand, authorization, direction, notice, consent, waiver or other action,
whether or not such Holders remain Holders after such record date.  No such
request, demand, authorization, direction, notice, consent, waiver or other
action shall be valid or effective if made, given or taken more than 90 days
after such record date.

          SECTION 1.05.  Notices, etc., to Trustee and Company.  Any request,
                         --------------------------------------              
demand, authorization, direction, notice, consent, waiver or Act of Holders or
other document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with:

          (i) 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 Principal Corporate Trust Office; or

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

          SECTION 1.06.  Notices to Holders; Waiver.  Where this Indenture or
                         ---------------------------                         
any Security provides for notice to Holders of any event:

          (1) such notice shall be sufficiently given (unless otherwise herein
     or in such Security expressly provided) if in writing and mailed, first
     class, postage prepaid, to each Holder of Registered Securities affected by
     such event, at his address as it
<PAGE>
 
                                                                              17

     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.

          (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, if the Securities of such series are then listed on The International
     Stock Exchange of the United Kingdom and the Republic of Ireland Limited
     and such stock exchange shall so require, in London and, if the Securities
     of such series are then listed on the Luxembourg Stock Exchange and such
     stock exchange shall so require, in Luxembourg and, if the Securities of
     such series are then listed on any other stock exchange and such stock
     exchange shall so require, in any other required city outside the United
     States, or, if not practicable, elsewhere in Europe 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.

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 Registered Securities shall affect
the sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice by publication to Holders of Bearer
Securities given as provided above.

          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 mailed to
Holders of Registered Securities as provided above.

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

          SECTION 1.07.  Language of Notices, etc.  Any request, demand,
                         -------------------------                      
authorization, direction, notice, consent, or waiver required or permitted under
this Indenture shall be in the English language, except that any published
notice may be in an official language of the country of publication.

extent that any provision of this Indenture limits, qualifies or conflicts with
the duties imposed by, or with another provision (an "incorporated provision")
included in this Indenture by operation of Sections 310 to 318, inclusive, of
the TIA, such imposed duties or incorporated provision shall control.

so expressed or not.

any way be affected or impaired thereby.

of the Securities or this Indenture) payment of the principal of, premium, if
any, or interest on any Securities need not be made at such Place of Payment on
such date, but may be made on the next succeeding Business Day with the same
force and effect as if made on the Interest Payment Date, Stated Maturity,
Repayment Date or Redemption Date or on the date on which Defaulted Interest is

securities of such series.  Any endorsement of a Global Security to reflect the
amount, or any increase or decrease in the amount, of Outstanding Securities
represented thereby shall be made 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 3.03 or Section 3.04.

          SECTION 3.02.  Denominations.  The Securities of each series shall be
                         --------------                                        
issuable in such form and denominations as shall be specified as contemplated by
Section 3.01.  In the absence of any specification with respect to the
Securities of any series, the Registered Securities of each series shall be
issuable only as Securities without coupons in denominations of $1,000 and any
integral multiple thereof and the Bearer Securities of each series, if any,
shall be issuable with coupons and in denominations of $5,000 and any integral
multiple thereof.

          SECTION 3.03.  Execution, Authentication, Delivery and Dating.  The
                         ----------------------------------------------      
Securities shall be executed on behalf of the Company by its Chairman of the
Board, its President, a Vice Chairman of the Board, or one of its Vice
Presidents and by its Secretary or one of its Assistant Secretaries.  The
signatures of any or all of these officers on the Securities may be manual or
facsimile.  Coupons shall bear the facsimile signature of the Company's Chairman
of the Board, its President, a Vice Chairman of the Board, one of its Vice
Presidents or the Treasurer.
<PAGE>
 
                                                                              26

          Securities and coupons 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 shall, upon receipt of the Company
Order, authenticate and deliver such Securities as in this Indenture provided
and not otherwise; provided, however, that, in connection with its original
                   --------  -------                                       
issuance, no Bearer Security shall be mailed or otherwise delivered to any
location in the United States; and provided further that a Bearer Security may
                                   ----------------                           
be delivered in connection with its original issuance only if the Person
entitled to receive such Bearer Security shall have delivered to the Trustee, or
such other Person as shall be specified in a temporary Global Security delivered
pursuant to Section 3.04, a Certificate in the form required by Section 3.11(i).

          If the Company shall establish pursuant to Section 3.01 that the
Securities of a series are to be issued in whole or in part in the form of one
or more Global Securities in registered or permanent bearer form, then the
Company shall execute and the Trustee shall, in accordance with this Section and
a Company Order for the authentication and delivery of such Global Securities
with respect to such series, authenticate and deliver one or more Global
Securities in permanent or temporary form that (i) shall represent and shall be
denominated in an aggregate amount equal to the aggregate principal amount of
the Outstanding Securities of such series to be represented by one or more
Global Securities, (ii) shall be registered, if in registered form, in the name
of the Depositary for such Global Security or Securities or the nominee of such
Depositary, and (iii) shall be delivered by the Trustee to such Depositary or
pursuant to such Depositary's instructions.

          Each Depositary designated pursuant to Section 3.01 for a Global
Security in registered form must,
<PAGE>
 
                                                                              27

at the time of its designation and at all times while it serves as Depositary,
be a clearing agency registered under the Exchange Act and any other applicable
statute or regulation.

          In authenticating such Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and (subject to Section 8.01) shall be
fully protected in relying upon, an Opinion of Counsel complying with Section
1.02 and stating that:

          (i) the form of such Securities and coupons, if any, has been
     established in conformity with the provisions of this Indenture;

         (ii) the terms of such Securities and coupons, if any, or the manner of
     determining such terms, have been established in conformity with the
     provisions of this Indenture;

        (iii) that such Securities and coupons, when authenticated and delivered
     by the Trustee and issued by the Company in the manner and subject to any
     conditions specified in such Opinion of Counsel, will constitute valid and
     legally binding obligations of the Company, enforceable in accordance with
     their terms, subject to bankruptcy, insolvency, reorganization, fraudulent
     transfer, moratorium and other laws of general applicability relating to or
     affecting the enforcement of creditors' rights and to general principles of
     equity; and

         (iv) such other matters as the Trustee may reasonably request.

          The Trustee shall not be required to authenticate such Securities if
the issue thereof will adversely affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

          Notwithstanding the provisions of Section 3.01 and of this Section
3.03, if all Securities of a series are not to be originally issued at one time,
it shall not be necessary to deliver the Board Resolution or Officers'
Certificate otherwise required pursuant to Section 3.01 or the Company Order and
Opinion of Counsel otherwise required
<PAGE>
 
                                                                              28

pursuant to this Section 3.03 at or prior to the time of authentication of each
Security of such series if such documents are delivered at or prior to the
authentication upon original issuance of the first Security of such series to be
issued and such documents reasonably contemplate the issuance of all Securities
of such series; provided that any subsequent request by the Company to the
                --------                                                  
Trustee to authenticate Securities of such series upon original issuance shall
constitute a representation and warranty by the Company that as of the date of
such request, the statements made in the Officers' Certificate or other
certificates delivered pursuant to Sections 1.02 and 3.01 shall be true and
correct as if made on such date.

          A Company Order, Officers' Certificate or Board Resolution or
supplemental indenture delivered by the Company to the Trustee in the
circumstances set forth in the preceding paragraph may provide that Securities
which are the subject thereof will be authenticated and delivered by the Trustee
or its agent on original issue from time to time in the aggregate principal
amount, if any, established for such series pursuant to such procedures
acceptable to the Trustee as may be specified from time to time by Company Order
upon telephonic, electronic or written order of Persons designated in such
Company Order, Officers' Certificate, supplemental indenture or Board Resolution
and that such Persons are authorized to determine, consistent with such Company
Order, Officers' Certificate, supplemental indenture or Board Resolution, such
terms and conditions of said Securities as are specified in such Company Order,
Officers' Certificate, supplemental indenture or Board   Resolution.

          Each Registered Security shall be dated the date of its
authentication; and unless otherwise specified as contemplated by Section 3.01,
each Bearer Security and any temporary Global Security referred to in Section
3.04 shall be dated as of the date of original issuance of such Security.

          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 manual signature, and
such certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
<PAGE>
 
                                                                              29

hereunder.  Except as permitted by Section 3.06, the Trustee shall not
authenticate and deliver any Bearer Security unless all appurtenant coupons for
interest then matured have been detached and canceled.  Notwithstanding the
foregoing, if any Security or portion thereof 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 3.09 together with a written statement (which need not comply with
Section 1.02 and need not be accompanied by an Opinion of Counsel) stating that
such Security or portion thereof 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 3.04.  Temporary Securities.  (a)  Pending the preparation of
                         ---------------------                                 
definitive Securities of any series, the Company may execute, and upon Company
Order and the receipt of the certifications and opinions required under Sections
3.01 and 3.03, the Trustee shall authenticate and deliver, temporary Securities
which are printed, lithographed, typewritten, mimeographed or otherwise
produced, in any authorized denominations, 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.  In the case of any series which may be issuable
as Bearer Securities, such temporary Securities may be in global form,
representing such of the Outstanding Securities of such series as shall be
specified therein.

          (b)  Unless otherwise provided pursuant to Section 3.01:

          (i)  Except in the case of temporary Securities in global form, each
     of which shall be exchanged in accordance with the provisions of the
     following paragraphs, if temporary Securities of any series are issued, the
     Company will cause definitive Securities of such series to be prepared
     without unreasonable delay.  After the preparation of definitive
     Securities, the temporary Securities of such series shall be exchangeable
     for definitive Securities of such series
<PAGE>
 
                                                                              30

     upon surrender of the temporary Securities of such series at the office or
     agency of the Company in a Place of Payment for that series, without charge
     to the Holder.  Upon surrender for cancellation of any one or more
     temporary Securities of any series (accompanied, if applicable, by all
     unmatured coupons and all matured coupons in default appertaining thereto),
     the Company shall execute and the Trustee shall authenticate and deliver in
     exchange therefor a like principal amount of definitive Securities of such
     series of authorized denominations; provided, however, that no definitive
                                         --------  -------                    
     Bearer Security shall be delivered in exchange for a temporary Registered
     Security; and provided further that a definitive Bearer Security shall be
                   ----------------                                           
     delivered in exchange for a temporary Bearer Security only in compliance
     with the conditions set forth in Section 3.03.  Until so exchanged, the
     temporary Securities of any series shall in all respects be entitled to the
     same benefits under this Indenture as definitive Securities of such series.

          (ii) If temporary Securities of any series are issued in global form,
     any such temporary Global Security shall, unless otherwise provided in such
     temporary Global Security, be delivered to the London office of a
     depositary or common depositary (the "Common Depositary"), for the benefit
     of the operator of Euroclear and 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).  Upon receipt of written instructions (which
     need not comply with Section 1.02) signed on behalf of the Company by any
     Person authorized to give such instructions, the Trustee or any
     Authenticating Agent shall endorse such temporary Global Security to
     reflect the initial principal amount, or an increase in the principal
     amount, of Outstanding Securities represented thereby.  Until such initial
     endorsement, such temporary Global Security shall not evidence any
     obligation of the Company.  Such temporary Global Security shall at any
     time represent the aggregate principal amount of Outstanding Securities
     theretofore endorsed thereon as provided above, subject to reduction to
     reflect exchanges as described below.

          (iii) Unless otherwise specified in such temporary Global Security,
     and subject to the second proviso in the following paragraph, the interest
     of a
<PAGE>
 
                                                                              31

     beneficial owner of Securities of a series in a temporary Global Security
     shall be exchanged for definitive Securities (including a definitive global
     Bearer Security) of such series and of like tenor following the Global
     Exchange Date (as defined below) when the account holder instructs
     Euroclear or CEDEL S.A., as the case may be, to request such exchange on
     his behalf and delivers to Euroclear or CEDEL S.A., as the case may be, a
     certificate in the form required by Section 3.11(i), dated no earlier than
     15 days prior to the Global Exchange Date, copies of which certificate
     shall be available from the offices of Euroclear and CEDEL S.A., the
     Trustee, any Authenticating Agent appointed for such series of Securities
     and each Paying Agent.  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
     Euroclear or CEDEL S.A.  Definitive Securities in bearer form to be
     delivered in exchange for any portion of a temporary Global Security shall
     be delivered only outside the United States.

          (iv) 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 as the "Global Exchange Date" (the "Global
     Exchange Date"), the Company shall deliver to the Trustee, or, if the
     Trustee appoints an Authenticating Agent pursuant to Section 8.14, to any
     such Authenticating Agent, definitive Securities in aggregate principal
     amount equal to the principal amount of such temporary Global Security,
     executed by the Company.  Unless otherwise specified as contemplated by
     Section 3.01, such definitive Securities shall be in the form of Bearer
     Securities or Registered Securities, or any combination thereof, as may be
     specified by the Company, the Trustee or any such Authenticating Agent, as
     may be appropriate.  On or after the Global Exchange Date, such temporary
     Global Security shall be surrendered by the Common Depositary to the
     Trustee or any such Authenticating Agent, as the Company's agent for such
     purpose, to be exchanged, in whole or from time to time in part, for
<PAGE>
 
                                                                              32

     definitive Securities without charge and the Trustee or any such
     Authenticating Agent 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, which, except as otherwise specified as
     contemplated by Section 3.01, shall be in the form of Bearer Securities or
     Registered Securities, or any combination thereof; provided, however, that,
                                                        --------  -------       
     unless otherwise specified in such temporary Global Security, upon such
     presentation by the Common Depositary, such temporary Global Security is
     accompanied by a certificate dated the Global Exchange Date or a subsequent
     date and signed by Euroclear as to the portion of such temporary Global
     Security held for its account then to be exchanged and a certificate dated
     the Global Exchange Date or a subsequent date and signed by CEDEL S.A., as
     to the portion of such temporary Global Security held for its account then
     to be exchanged, each in the form required by Section 3.11(ii); and
                                                                        
     provided further that a definitive Bearer Security (including a definitive
     ----------------                                                          
     global Bearer Security) shall be delivered in exchange for a portion of a
     temporary Global Security only in compliance with the conditions set forth
     in Section 3.03.

          (v) Upon any exchange of a portion of any such temporary Global
     Security, such temporary Global Security shall be endorsed by the Trustee
     or any such Authenticating Agent, as the case may be, to reflect the
     reduction of the principal amount evidenced thereby, whereupon its
     remaining principal amount shall be reduced for all purposes by the amount
     so exchanged.  Until so exchanged in full, such temporary Global Security
     shall in all respects be entitled to the same benefits under this Indenture
     as definitive Securities of such series authenticated and delivered
     hereunder, except that, unless otherwise specified as contemplated by
     Section 3.01, interest payable on such temporary Global Security on an
     Interest Payment Date for Securities of such series occurring prior to the
     applicable Global Exchange Date shall be payable, without interest, to
     Euroclear and CEDEL S.A. on or after such Interest Payment Date upon
     delivery by Euro clear and CEDEL S.A. to the Trustee or the Paying Agent,
     as the case may be, of a certificate or

                                                                              33

     certificates in the form required by Section 3.11(iii), for credit 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 Euroclear or CEDEL
     S.A., as the case may be, a certificate in the form required by Section
     3.11(iv). Any interest so received by Euroclear and CEDEL S.A. and not paid
     as herein provided prior to the Global Exchange Date shall be returned to
     the Trustee or Paying Agent, as the case may be, which, upon expiration of
     two years after such Interest Payment Date, shall repay such interest to
     the Company on Company Request in accordance with Section 5.03.

          SECTION 3.05.  Registration, Registration of Transfer and Exchange.
                         ---------------------------------------------------- 
With respect to Registered Securities, the Company shall keep or cause to be
kept a register (sometimes 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 Registered Securities and the registration of
transfers of Registered Securities and the Company shall appoint a "Security
Registrar", and may appoint any "Co-Security Registrar" as may be appropriate,
to keep the Security Register.  Such Security Register shall be in written form
or in any other form capable of being converted into written form within a
reasonable time.  At all reasonable times the information contained in such
Security Register shall be available for inspection by the Trustee at the office
of the Security Registrar.  In the event that any Registered Securities issued
hereunder have The City of New York as a Place of Payment, the Company shall
appoint either a Security Registrar or Co-Security Registrar located in The City
of New York.

          Upon surrender for registration of transfer of any Registered Security
of any series at the office or agency of the Company maintained pursuant to
Section 5.02 for such purpose in a Place of Payment for such series, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Registered Securities
of such series of any authorized denominations and of a like aggregate principal
amount, tenor and Stated Maturity.

          At the option of the Holder, Registered Securities of any series may
be exchanged for other Registered

Securities of such series, of any authorized denominations and of like aggregate
principal amount, tenor and Stated Maturity, upon surrender of the Securities to
be exchanged at such office or agency.  Whenever any Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

          Registered Securities may not be exchanged for Bearer Securities.

          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 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 in an amount equal to the face amount of such missing coupon or
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there be furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless.  If
thereafter the Holder of such Security shall surrender to any Paying Agent any
such missing coupon in respect of which such a payment shall have been made,
such Holder shall be entitled to receive the amount of any such payment from the
Company; provided, however, that interest represented by coupons shall be
         --------  -------                                               
payable only upon presentation and surrender of those coupons at an office or
agency of a Paying Agent, maintained pursuant to Section 5.02 for such purpose,
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 like tenor after the
close of business at such office or agency on (i) any Regular Record Date and
before the opening of business at such office or agency on the relevant Interest
Payment Date, or (ii) any Special Record Date and before the opening of business
at such office or agency on the related date for payment of Defaulted Interest,
such Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be.

          Notwithstanding any other provision of this Section, unless and until
it is exchanged in whole or in part for individual Securities represented
thereby, a Global Security representing all or a portion of the Securities of a
series may not be transferred except as a whole by the Depositary for such
series to a nominee of such Depositary or by a nominee of such Depositary to
such Depositary or another nominee of such Depositary or by such Depositary or
any such nominee to a successor Depositary for such series or a nominee of such
successor Depositary.

          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.

          If at any time the Depositary for the Securities of a series notifies
the Company that it is unwilling or unable to continue as Depositary for the
Securities of such series or if at any time the Depositary for the Securities of
such series shall no longer be eligible under Section 3.03, the Company shall
appoint a successor Depositary with respect to the Securities of such series. If
a successor Depositary for the Securities of such series is not appointed by the
Company within 90 days after the Company receives such notice or becomes aware
of such ineligibility, the Company's election pursuant to Section 3.01(vi) shall
no longer be effective with respect to the Securities of such series and the
Company will execute, and the Trustee, upon receipt of a Company Order for the
authentication and delivery of definitive Securities of such series, will
authenticate and deliver Securities of such series of like tenor and terms in
definitive form in an aggregate principal amount equal to the principal amount
of the Global Security or Securities representing such series in exchange for
such Global Security or Securities.

          The Company may at any time and in its sole discretion determine that
the Securities of any series issued in the form of one or more Global Securities
shall no longer be represented by such Global Security or Securities. In such
event, the Company will execute, and the Trustee, upon receipt of a Company
Order for the authentication and delivery of definitive Securities of such
series, will authenticate and deliver, Securities of such series of like tenor
and terms in definitive form in an aggregate principal amount equal to the
principal amount of the Global Security

or Securities representing such series in exchange for such Global Security or
Securities.

          If specified by the Company pursuant to Section 3.01 with respect to a
series of Securities, the Depositary for such series of Securities may surrender
a Global Security for such series of Securities in exchange in whole or in part
for Securities of such series of like tenor and terms and in definitive form on
such terms as are acceptable to the Company, the Trustee and such Depositary.
Thereupon, the Company shall execute, and the Trustee upon receipt of a Company
Order for the authentication and delivery of definitive Securities of such
series, shall authenticate and deliver, without service charge:

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

          (b) to such Depositary a new Global Security of like tenor and terms
     and in an authorized denomination equal to the difference, if any, between
     the principal amount of the surrendered Global Security and the aggregate
     principal amount of Securities delivered to Holders thereof.

          In any exchange provided for in any of the preceding three paragraphs,
the Company will execute and the Trustee, pursuant to a Company Order, will
authenticate and deliver, Securities (a) in definitive registered form in
authorized denominations, if the Securities of such series are issuable as
Registered Securities, (b) in definitive bearer form in authorized
denominations, with coupons attached, if the Securities of such series are
issuable as Bearer Securities or (c) as either Registered or Bearer Securities,
if the Securities of such series are issuable in either form; provided, however,

in such names and in such authorized denominations, and delivered to such
addresses, as the Depositary for such Global Security, pursuant to instructions
from its direct or indirect participants or otherwise, shall instruct the
Trustee in writing. The Trustee shall deliver such Registered Securities to the
Persons in whose names such Securities are so registered or to the Depositary.
The Trustee shall deliver Bearer Securities issued in exchange for a Global
Security pursuant to this Section 3.05 to the Depositary or to the Persons at
such addresses, and in such authorized denominations, as the Depositary for such
Global Security, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee in writing; provided,

temporary Global Security other than in accordance with the provisions of
Sections 3.03 and 3.04.

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

          Every Security presented or surrendered for registration of transfer
or exchange shall (if so required by the Company or the Security Registrar) 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.

          Unless otherwise provided in the Securities to be registered for
transfer or exchanged, no service charge shall be made for any registration of
transfer or exchange of Securities, but the Company may (unless otherwise
provided in such Securities) 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
expressly provided in this Indenture to be made at the Company's own expense or
without expense or without charge to the Holders.

          Neither the Company, the Security Registrar nor any Co-Security
Registrar shall be required (i) to issue, register the transfer of or exchange
any Securities of any series during a period beginning at the opening of
business 15 days before the day of selection of Securities of such series to be
redeemed and ending 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 of Registered Securities of such series so
selected for redemption or (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 or exchange of any Securities or
portions thereof so selected for redemption.

          Notwithstanding anything herein to the contrary, the exchange of
Bearer Securities into Registered Securities shall be subject to applicable laws
and regulations in effect at the time of exchange; none of the Company, the
Trustee nor the Security Registrar shall exchange any Bearer Securities into
Registered Securities if it has received an Opinion of Counsel that as a result
of such exchanges the Company would suffer adverse consequences under the United
States Federal income tax laws and regulations then in effect and the Company
has delivered to the Trustee a Company Order directing the Trustee not to make
such exchanges unless and until the Trustee receives a subsequent Company Order
to the contrary. The Company shall deliver copies of such Company Orders to the
Security Registrar.

                         -------------------------------------------------    
(i) any mutilated Security or Security with a mutilated coupon is surrendered to
the Trustee or the Security Registrar, or if the Company, the Trustee and the
Security Registrar receive evidence to their satisfaction of the destruction,
loss or theft of any Security or coupon and (ii) there is delivered to the
Company, the Trustee and the Security Registrar such security or indemnity as
may be required by them to save each of them harmless, then, in the absence of
notice to the Company, the Trustee or the Security Registrar that such Security

its request the Trustee shall authenticate and deliver, in lieu of any such

Security to which a mutilated, destroyed, lost or stolen coupon appertains (with
all appurtenant coupons not mutilated, destroyed, lost or stolen), a new
Security of the same series and Stated Maturity and of like tenor and principal
amount, bearing a number not contemporaneously outstanding and, if applicable,
with coupons corresponding to the coupons appertaining thereto; provided,
                                                                --------

the conditions set forth in Section 3.05.

          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; provided,
                                                                      --------

Bearer Securities shall be payable only at an office or agency located outside
the United States, and, in the ease of interest, unless otherwise specified as
contemplated by Section 3.01, only upon presentation and surrender of the
coupons appertaining thereto.

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

          Every new Security of any series, with its coupons, if any, issued
pursuant to this Section in exchange for any mutilated security or in lieu of
any destroyed, lost or stolen Security, or in exchange for a Security with a
mutilated, destroyed, lost or stolen coupon, shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Security and its coupons, if any, or the mutilated,
destroyed, lost or stolen coupon shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture
equally and proportionately with any and all other Securities of the same series
and their coupons, if any, duly issued hereunder.

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

                         -----------------------------------------------        
otherwise provided as contemplated by Section 3.01, interest on any Registered
Security which is payable, and is punctually paid or duly provided for, on any
Interest Payment Date shall unless otherwise provided in such Security 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. Unless otherwise specified as contemplated by Section 3.01,
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 referred to in Section 3.05) 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. At the option of
the Company, payment of interest on any Registered Security may be made by check
in the currency designated for such payment pursuant to the terms of such
Registered Security mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register or by wire transfer to an account
in such currency designated by such Person in writing not later than ten days
prior to the date of such payment.

          Any interest on any Registered Security 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 his having been such Holder,
and such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (i) or clause (ii) below.

          (i) The Company may elect to make payments of any Defaulted Interest
     to the Persons in whose names any such Registered Securities (or their
     respective Predecessor Securities) are registered at the close of business
     on a Special Record Date for the payment of such Defaulted Interest, which
     shall be fixed in the following manner. The Company shall notify the
     Trustee in writing of the amount of Defaulted Interest proposed to be paid
     on each Registered Security and the date of
<PAGE>
 
     the proposed payment, and at the same time the Company shall deposit with
     the Trustee an amount of money equal to the aggregate amount proposed to be
     paid in respect of such Defaulted Interest or shall make arrangements
     satisfactory to the Trustee for such deposit prior to the date of the
     proposed payment, such money when deposited to be held in trust for the
     benefit of the Persons entitled to such Defaulted Interest as in this
     clause provided. Thereupon the Trustee shall fix a Special Record Date for
     the payment of such Defaulted Interest which shall be not more than 15 nor
     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 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
     mailed as aforesaid, such Defaulted Interest shall be paid to the Persons
     in whose names such Registered Securities (or their respective Predecessor
     Securities) are registered on such Special Record Date and shall no longer
     be payable pursuant to the following clause (ii). In case a Bearer Security
     of any series is surrendered at the office or agency in a Place of Payment
     for such series in exchange for a Registered Security of such series after
     the close of business at such office or agency on any Special Record Date
     and before the opening of business at such office or agency on the related
     proposed date of payment of Defaulted Interest, such Bearer Security shall
     be surrendered without the coupon relating to such proposed date for
     payment and Defaulted Interest will not be payable on such proposed date
     for payment 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.

         (ii) The Company may make payment of any Defaulted Interest in any
     other lawful manner not inconsistent with the requirements of any
     securities exchange on which the Securities with respect to which
<PAGE>

     there exists such default 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 payment shall
     be deemed practicable by the Trustee.

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

          Subject to the limitations set forth in Section 5.02, the Holder of
any coupon appertaining to a Bearer Security shall be entitled to receive the
interest payable on such coupon upon presentation and surrender of such coupon
on or after the Interest Payment Date of such coupon at an office or agency
maintained for such purpose pursuant to Section 5.02.

          SECTION 3.08.  Persons Deemed Owners.  Title to any Bearer Security,

any coupons appertaining thereto and any temporary Global Security shall pass by
delivery.

          Prior to due presentment for registration of transfer of any
Registered Security, the Company, the Trustee and any agent of the Company or
the Trustee may treat the Person in whose name such Security is registered as
the owner of such Security for the purpose of receiving payment of principal of,
premium, if any, and (subject to Section 3.07) interest on such Security, and
for all purposes whatsoever, whether or not such Security be overdue, and
neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.

          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 Security or coupon for the purpose of receiving payment
thereof or on account thereof and for all other purposes whatsoever, whether or
not such 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, any Authenticating
Agent or the Security Registrar will have the responsibility or liability for
any aspect of the records relating to or payments made on account of beneficial
ownership interest of a Global Security or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interest, and they
shall be fully protected in acting or refraining from acting on any such
information provided by the Depositary.

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

                         ----------                                      
Section 3.01, for the Securities of any series that, to the fullest extent
possible under applicable law and except as may otherwise be specified as
contemplated in Section 3.01, (a) the obligation, if any, of the Company to pay
the principal of (and premium, if any) and interest of the Securities of any
series and any appurtenant coupons in a Foreign Currency, composite currency or
Dollars (the "Designated Currency") as may be specified pursuant to Section 3.01
is of the essence and agrees that judgments in respect of such Securities shall
be given in the Designated Currency; (b) the obligation of the Company to make
payments in the Designated Currency of the principal of (and premium, if any)
and interest on such Securities and any appurtenant coupons shall,
notwithstanding any payment in any other currency (whether pursuant to a
judgment or otherwise), be discharged only to the extent of the amount in the
Designated Currency that the Holder receiving such payment may, in accordance
with normal banking procedures, purchase with the sum paid in such other
currency (after any premium and cost of exchange) in the country of issue of the
Designated Currency in the case of Foreign Currency or Dollars or in the
international banking community in the case of a composite currency on the
Business Day immediately following the day on which such Holder receives such

payment; (c) if the amount in the Designated Currency that may be so purchased
for any reason falls short of the amount originally due, the Company shall pay
such additional amounts as may be necessary to compensate for such shortfall;
and (d) any obligation of the Company not discharged by such payment shall be
due as a separate and independent obligation and, until discharged as provided
herein, shall continue in full force and effect.

                           Redemption of Securities
                           ------------------------

          SECTION 4.01.  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 3.01 for Securities of any series, in accordance with this Article.

          SECTION 4.02.  Election To Redeem; Notice To Trustee.  The election of
                         --------------------------------------                 
the Company to redeem any Securities redeemable at the option of the Company
shall be evidenced by an Officers' Certificate. In case of any redemption at the
election of the Company of less than all the Securities of any series, the
Company shall, at least 60 days prior to the Redemption Date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee and the Security Registrar of such Redemption Date and of the
principal amount of Securities of such series to be redeemed. In the case of any
redemption of Securities (i) prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, or (ii) pursuant to an election of the Company which is subject to a
condition specified in the terms of such Securities, the Company shall furnish
the Trustee with an Officers' Certificate evidencing compliance with such
restriction.

          SECTION 4.03.  Selection by Security Registrar of Securities To Be
                         ---------------------------------------------------
Redeemed.  If less than all the Securities of any series with the same 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 Security Registrar from
the Outstanding Securities of such series having such terms not previously
called for redemption, by such method as the Security Registrar shall

                                                                              46

deem fair and appropriate and which may provide for the selection for redemption
of portions of the principal amount of Securities of such series of a
denomination equal to or larger than the minimum authorized denomination for
Securities of such series. Unless otherwise provided by the terms of the
Securities of any series so selected for partial redemption, the portions of the
principal of Securities of such series so selected for partial redemption shall
be, in the case of Registered Securities, equal to $1,000 or an integral
multiple thereof or, in the case of Bearer Securities, equal to $5,000 or an
integral multiple thereof, and the principal amount of any such Security which
remains outstanding shall not be less than the minimum authorized denomination
for Securities of such series.

          The Security Registrar shall promptly notify the Company, the Trustee
and the Co-Security Registrar, if any, in writing of the Securities selected for
redemption and, in the case of any Security 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 Security redeemed or to be redeemed only in part, to the
portion of the principal of such Security which has been or is to be redeemed.

          SECTION 4.04.  Notice of Redemption.  Notice of redemption shall be
                         ---------------------                               
given in the manner provided in Section 1.06, not less than 30 nor more than 60
days prior to the Redemption Date, to each Holder of Securities to be redeemed.

          All notices of redemption shall state:

          (i) the Redemption Date;

         (ii) the Redemption Price;

        (iii) if less than all Outstanding Securities of any series having the
     same terms are to be redeemed, the identification (and, in the case of
     partial redemption, the respective principal amounts) of the particular
     Securities to be redeemed;

         (iv) that on the Redemption Date the Redemption Price will become due
     and payable upon each such
<PAGE>
 
                                                                              47

     Security to be redeemed, and that interest, if any, thereon shall cease to
     accrue on and after said date;

          (v) the place or places where such Securities, together in the case of
     Bearer Securities with all remaining coupons appertaining thereto, if any,
     maturing after the Redemption Date, are to be surrendered for payment of
     the Redemption Price;

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

        (vii) the CUSIP number or the Euroclear or the CEDEL reference numbers
     (or any other number used by a Depository to identify such Securities), if
     any, of the Securities to be redeemed.

          A notice of redemption published as contemplated by Section 1.06 need
not identify particular Registered Securities to be redeemed.

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

          SECTION 4.05.  Deposit of Redemption Price.  At or prior to the
                         ----------------------------                    
opening of business on any Redemption Date, the Company shall deposit or cause
to be deposited 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 5.03) an amount of money sufficient to pay the Redemption Price of all
the Securities which are to be redeemed on that date; provided, however, that
                                                      --------  -------      
deposits with respect to Bearer Securities shall be made with a Paying Agent or
Paying Agents located outside the United States except as otherwise provided in
Section 5.02, unless otherwise specified as contemplated by Section 3.01.

          SECTION 4.06.  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) 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

                                                                              48

void. Upon surrender of any such Securities for redemption in accordance with
said notice, such Securities shall be paid by the Company at the Redemption
Price; provided, however, that installments of interest on Bearer Securities
       --------  -------                                                    
whose Stated Maturity is on or prior to the Redemption Date shall be payable
only at an office or agency located outside the United States and, unless
otherwise specified as contemplated by Section 3.01, only upon presentation and
surrender of coupons for such interest. 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 on the close of business on the relevant Regular
Record Dates according to their terms and the provisions of Section 3.07.

          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 and, unless otherwise specified as
contemplated by Section 3.01, only upon presentation and surrender of those
coupons.

          If any Security called for redemption shall not be paid upon surrender
thereof for redemption, the principal shall, until paid, bear interest from the
Redemption Date at the rate borne by such Security, or as otherwise provided in
such Security.

          SECTION 4.07.  Securities Redeemed in Part.  Any Security which is to
                         ----------------------------                          
be redeemed only in part shall be surrendered at the office or agency of the
Company in a Place of Payment therefor (with, if the Company or the Security
Registrar so requires, due endorsement by, or a written instrument of transfer
in form satisfactory to the Company and the Security Registrar duly executed by,

Holder of such Security or his attorney duly authorized in writing), and the
Company shall execute, and the Trustee shall authenticate and deliver to the
Holder of such Security without service charge, a new Security or Securities of
the same series and Stated Maturity, containing identical terms and conditions,
of any authorized denominations 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.

                         -------------------------------------------     
Company covenants and agrees for the benefit of each series of Securities that
it will duly and punctually pay the principal of, premium, if any, and interest
on the Securities of such series in accordance with the terms of the Securities
of such series, any coupons appertaining thereto and this Indenture. Unless
otherwise specified as contemplated by Section 3.01 with respect to any series
of Securities, any interest due on Bearer Securities on or before Maturity shall
be payable only outside the United States upon presentation and surrender of the
several coupons for such interest installments as are evidenced thereby as they
severally mature.

          SECTION 5.02.  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 any series of Securities an office or agency where
Securities of that series may be presented or surrendered for payment, where
Securities of that series may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Company in respect of the
Securities of that series and this Indenture may be served. The Company will
give prompt written notice to the Trustee of the location, and of any change in
the location, of such office or agency. If Securities of a series may be
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 and
where notices and

this Indenture may be served, (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
5.04); provided, however, that if the Securities of that series are listed on

The International Stock Exchange of the United Kingdom and the Republic of
Ireland Limited or 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
or 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 such series 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 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 Principal 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 5.04) at the place specified for the purpose as contemplated by
Section 3.01, and the Company hereby appoints the Trustee as its agent to
receive such respective presentations, surrenders, notices and demands.

          Except as otherwise provided in the form of Bearer Security of any
particular series pursuant to the provisions of this Indenture, no payment of
principal, premium or interest on Bearer Securities shall be made at any office
or agency of the Company in the United States or by check mailed to any address
in the United States or by transfer to

Dollars (including additional amounts payable in respect thereof) on any Bearer
Security may be made at an office or agency of, and designated by, the Company
located in the United States if (but only if) payment of the full amount of such
principal, premium, interest or additional amounts in Dollars at all offices
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 similar restrictions and the Trustee receives an Opinion of Counsel
that such payment within the United States is legal.  Unless otherwise provided
as contemplated by Section 3.01 with respect to any series of Securities, at the
option of the Holder of any Bearer Security or related coupon, payment may be
made by check in the currency designated for such payment pursuant to the terms
of such Bearer Security presented or mailed to an address outside the United
States or by transfer to an account in such currency maintained by the payee
with a bank located outside the United States.

          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 of such purposes specified above in this Section
and may constitute and appoint one or more Paying Agents for the payment of such
Securities, in one or more other cities, and may from time to time rescind such
designations and appointments; provided, however, that no such designation,

appointment or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in each Place of Payment for
Securities of any series for such purposes.  The Company will give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency.  Unless and until the
Company rescinds one or more such appointments, the Company hereby appoints:
(i) the Trustee, as its Paying Agent in The City of New York with respect to all
series of Securities having a Place of Payment in The City of New York and (ii)
the [    ] at its principal office as its Paying Agent in the [              ]

          SECTION 5.03.  Money for Security Payments To Be Held in Trust.  If
                         ------------------------------------------------    
the Company shall at any time act as its own Paying Agent for any series of
Securities, it will, on
<PAGE>
 
                                                                              51

or before each due date of the principal of, premium, if any, or interest on any
of the Securities of such series and any appurtenant coupons, segregate and hold
in trust for the benefit of the Persons entitled thereto a sum sufficient to pay
the principal, premium or interest so becoming due until such sums shall be paid
to such Persons or otherwise disposed of as herein provided, and will promptly
notify the Trustee of its action or failure so to act.

          Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, at or prior to the opening of business on each
due date of the principal of, premium, if any, or interest on any Securities of
such series and any appurtenant coupons, deposit with a Paying Agent a sum
sufficient to pay the principal, premium or interest so becoming due, such sum
to be held in trust for the benefit of the Persons entitled to such principal,
premium or interest, and (unless such Paying Agent is the Trustee) the Company
will promptly notify the Trustee of its action or failure so to act.

          The Company will cause each Paying Agent other than the Trustee for
any series of Securities 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:

          (i) hold all sums held by it for the payment of principal of, premium,
     if any, or interest on Securities of such series and any appurtenant
     coupons 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;

         (ii) 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, premium or interest on the Securities of such series
     or any appurtenant coupons; and

        (iii) 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 payments 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, premium, if any,
or interest on any Security of any series or any appurtenant coupons and
remaining unclaimed for two years after such principal, premium 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 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 5.04.  Additional Amounts.  If the Securities of a series
                         -------------------                               
provide for the payment of additional amounts, the Company will pay to the
Holder of any Security of any 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 premium, if any)
or interest on, or in respect of, any Security of any series or payment of any
related coupon or the net proceeds received on the sale or exchange of any
Security of any series, such mention shall be deemed to include mention of the
payment of additional amounts provided 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
<PAGE>
 
                                                                              54

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 (and
premium, if any) is made), and at least 10 days prior to each date of payment of
principal (and premium, if any) or 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 Principal 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 premium, if any) or interest on the Securities of
that series shall be made to Holders of Securities of that series or any related
coupons who are United States Aliens 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'

          SECTION 6.02.  Preservation of Information; Communications to Holders.
                         -------------------------------------------------------
(i)  The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders of Securities contained in the
most recent list furnished to the Trustee as provided in Section 6.01 and the
names and addresses of Holders of Securities received by the Trustee in its
capacity as the Security Registrar, if so acting.  The Trustee may destroy any
list furnished to it as provided in Section 6.01 upon receipt of a new list so
furnished.

          (ii)  If three or more Holders of Securities of any series
(hereinafter referred to as "applicants") apply in writing to the Trustee, and
furnish to the Trustee reasonable proof that each such applicant has owned a
Security of such series for a period of at least six months preceding the date
of such application, and such application states that the applicants desire to
communicate with other Holders of Securities of such series or with the Holders
of all Securities with respect to their rights under this Indenture or under
such Securities and is accompanied by a copy of the form of proxy or other
communication which such applicants propose to transmit, then the Trustee shall,
within five Business Days after the receipt of such application, at its
election, either

          (a) afford such applicants access to the information preserved at the
     time by the Trustee in accordance with Section 6.02(i), or

          (b) inform such applicants as to the approximate number of Holders of
     Securities of such series or all Securities, as the case may be, whose
     names and addresses appear in the information preserved at the time by the
     Trustee in accordance with Section 6.02(i), and as to the approximate cost
     of mailing to such

                                                                              57

     application.

          If the Trustee shall elect not to afford such applicants access to
such information, the Trustee shall, upon the written request of such
applicants, mail to each Holder of a Security of such series or all Holders of
Securities, as the case may be, whose names and addresses appear in the
information preserved at the time by the Trustee in accordance with Section
6.02(i), a copy of the form of proxy or other communication which is specified
in such request, with reasonable promptness after a tender to the Trustee of the
material to be mailed and of payment, or provision for the payment, of the
reasonable expenses of mailing, unless, within five days after such tender, the
Trustee shall mail to such applicants and file with the Commission, together
with a copy of the material to be mailed, a written statement to the effect
that, in the opinion of the Trustee, such mailing would be contrary to the best
interests of the Holders of Securities of such series or all Securities, as the
case may be, or would be in violation of applicable law.  Such written statement
shall specify the basis of such opinion.  If the Commission, after opportunity
for a hearing upon the objections specified in the written statement so filed,
shall enter an order refusing to sustain any of such objections or if, after the
entry of an order sustaining one or more of such objections, the Commission
shall find, after notice and opportunity for hearing, that all the objections so
sustained have been met and shall enter an order so declaring, the Trustee shall
mail copies of such material to all such Holders of Securities with reasonable
promptness after the entry of such order and the renewal of such tender;
otherwise, the Trustee shall be relieved of any obligation or duty to such
applicants respecting their application.

          (iii)  Every Holder of Securities, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee
shall be held accountable by reason of the disclosure of any such information as
to the names and addresses of the Holders of Securities in accordance with
Section 6.02(ii), regardless of the source from which such information was
derived, and that the Trustee shall not be held accountable by reason of mailing
any material pursuant to a request made under Section 6.02(ii).

                         ---------------------------------------------------    
an Event of Default with respect to any series of Securities for which there are
Securities 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 such series may declare the principal of all the
Securities of such series (or, if the Securities of that series are Original
Issue Discount Securities, such portion of the principal amount as may be
specified in the terms of that series) to be immediately due and payable, by a
notice in writing to the Company (and to the Trustee if given by Holders), and
upon any such declaration the same 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 such series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences, and any
Event of Default giving rise to such declaration shall not be deemed to have
occurred, if:

     sufficient to pay

          Trustee, the Security Registrar, any Paying Agent, and their agents
          and counsel and all other amounts due the Trustee under Section 8.07;
          and

         (ii) all Events of Default with respect to Securities of that series,
     other than the nonpayment of the principal of Securities of that series
     which have become due solely by such declaration of acceleration, have been
     cured or waived as provided in Section 7.13.

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

          SECTION 7.03.  Collection of Indebtedness and Suits for Enforcement by
                         -------------------------------------------------------
Trustee.  The Company covenants that if:
- --------                                

          (i) default is made in the payment of any instalment of interest on
     any Security of any series when such interest becomes due and payable and
     such default continues for a period of 30 days; or

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holder of any such Security or coupon appertaining thereto, if any, the whole
amount then due and payable on any such Security or coupon for principal,
premium, if any, and interest, with interest upon the overdue principal and
premium, if any, and (to the extent that payment of such interest shall be
lawful) upon overdue installments of interest, at the rate or rates prescribed
therefor by the terms of any such Security; and, in addition thereto, such
further amount as shall be sufficient to cover the reasonable costs and expenses
of collection, including the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel and any other amounts due
the Trustee under Section 8.07.

          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, and 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

property of the Company or any other obligor upon such Securities, wherever
situated.

          If an Event of Default with respect to any series of Securities 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.

pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial

Trustee (irrespective of whether the principal of any 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, premium, if any, 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,
     premium, if any, and interest owing and unpaid in respect of the Securities
     and to file such other papers or documents as may be necessary or advisable
     in order to have the claims of the Trustee (including any claim for the
     reasonable compensation, expenses, disbursements and advances of the
     Trustee, its agents and counsel and any other amounts due the Trustee under
     Section 8.07) and of the Holders allowed in such judicial proceeding; and

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

and any receiver, assignee, trustee, liquidator, sequestrator or other similar
official in any such judicial proceeding is hereby authorized by each Holder to
make such payments to the Trustee, and in the event that the Trustee

shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 8.07.

          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 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.

Securities of any series, or coupons (if any) appertaining thereto, may be
prosecuted and enforced by the Trustee without the possession of any of the
Securities of such series or coupons appertaining thereto 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 and any other amounts due the Trustee under Section 8.07,
be for the ratable benefit of the Holders of the Securities of such series and
coupons appertaining thereto in respect of which such judgment has been
recovered.

                                                                              65

          SECOND:  To the payment of the amounts then due and unpaid upon the

     interest on such series of Securities in the currency in which such series
     of Securities is denominated into Dollars at the Exchange Rate as of the
     date of declaration of acceleration of the Maturity of the Securities; and

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:

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

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

        (iii) 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;

         (iv) the Trustee for 60 days after its receipt of such notice, request
     and offer of indemnity has failed to institute any such proceeding; and
<PAGE>
 
                                                                              66

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

it being understood and intended that no one or more Holders of Securities of
such series 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 of Securities of such series or to obtain or to seek
to obtain priority or preference over any other such Holders or to enforce any
right under this Indenture, except in the manner herein provided and for the
equal and ratable benefit of all the Holders of Securities of such series.

          SECTION 7.08.  Unconditional Right of Holders To Receive Principal,
                         ----------------------------------------------------
Premium and Interest.  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, premium, if any, and
(subject to Section 3.07) interest on such Security or payment of such coupon on
the respective Stated Maturities expressed in such Security or coupon (or, in
the case of redemption or repayment, on the Redemption Date or Repayment Date)
and to institute suit for the enforcement of such payment, and such rights shall
not be impaired without the consent of such Holder.

          SECTION 7.09.  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 the Company, the Trustee and the
Holders shall, subject to any determination in such proceeding, be restored
severally and respectively to their former positions hereunder, and thereafter
all rights and remedies of the Trustee and the Holders shall continue as though
no such proceeding had been instituted.

          SECTION 7.10.  Rights and Remedies Cumulative.  Except as otherwise 
                         -------------------------------
provided with respect to the replacement or payment of mutilated, lost,

no right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any
<PAGE>
 
                                                                              67

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 7.11.  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 may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by the Holders, as the case may be.

          SECTION 7.12.  Control by Holders.  The Holders of a majority in
                         -------------------                              
principal amount of the Outstanding Securities of any series shall have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on
the Trustee with respect to the Securities of such series; provided that:
                                                           --------      

          (i) such direction shall not be in conflict with any rule of law or
     with this Indenture;

         (ii) the Trustee shall not determine that the action so directed would
     be unjustly prejudicial to the Holders not taking part in such direction;

        (iii) subject to the provisions of Section 8.01, the Trustee shall have
     the right to decline to follow any such direction if the Trustee in good
     faith shall, by a Responsible Officer or Officers of the Trustee, determine
     that the proceeding so directed would involve the Trustee in personal
     liability; and

         (iv) the Trustee may take any other action deemed proper by the Trustee
     which is not inconsistent with such direction.

          SECTION 7.13.  Waiver of Past Defaults.  The Holders of a majority in
                         ------------------------

the Holders of all

the Securities of such series waive any past default hereunder and its
consequences, except a default not theretofore cured:

          (i) in the payment of the principal of, premium, if any, or interest
     on any Security of such series; or

         (ii) 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 the Securities of such series under this Indenture; but no such
waiver shall extend to any subsequent or other default or impair any right
consequent thereon.

          SECTION 7.14.  Undertaking for Costs.  All parties to this Indenture
                         ----------------------                               
agree, and each Holder of any Security by his acceptance thereof shall be deemed
to have agreed, that any court may in its discretion require, in any suit for
the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken, suffered or omitted by it as Trustee,
the filing by any party litigant in such suit of an undertaking to pay the costs
of such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant; but the provisions of this Section shall not apply to any
suit instituted by the Company, to any suit instituted by the Trustee, to any
suit instituted by any Holder, or group of Holders, holding in the aggregate
more than 10% in principal amount of the Outstanding Securities of any series,
or to any suit instituted by any Holder of Securities or coupons for the
enforcement of the payment of the principal of, premium, if any, or interest on
any Security or payment of any coupon on or after the respective Stated
Maturities expressed in such Security or coupon (or, in the case of redemption
or repayment, on or after the Redemption Date or Repayment Date).

          SECTION 7.15.  Waiver of Stay or Extension Laws.  The Company
                         ---------------------------------             
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or

                                                                              69

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


                                 ARTICLE EIGHT

                                  The Trustee

          SECTION 8.01.  Certain Duties and Responsibilities.  (i)  Except
                         ------------------------------------             
during the continuance of an Event of Default with respect to any series of
Securities:

          (a) the Trustee undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture with respect to Securities
     of such series, and no implied covenants or obligations shall be read into
     this Indenture against the Trustee with respect to such series; and

          (b) in the absence of bad faith on its part, the Trustee may
     conclusively rely with respect to such series, 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 certificate 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 as to form to the
     requirements of the Indenture.

         (ii)  In case an Event of Default with respect to any series of
Securities has occurred and is continuing, the Trustee shall exercise such of
the rights and powers vested in it by this Indenture with respect to 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 or her own affairs.

                                                                              70

        (iii)  No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own wilful misconduct, except that:

          (a) this Subsection shall not be construed to limit the effect of
     Subsection (i) of this Section;

          (b) the Trustee shall not be liable for any error or judgment made in
     good faith by a Responsible Officer, unless it shall be proved that the
     Trustee was negligent in ascertaining the pertinent facts;

          (c) the Trustee shall not be liable with respect to any action taken,
     suffered 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 Securities of such series; and

          (d) no provision of this Indenture shall require the Trustee to expend
     or risk its own funds or otherwise incur any financial liability in the
     performance of any of its duties hereunder, or in the exercise of any of
     its rights or powers, if it shall have reasonable grounds for believing
     that repayment of such funds or adequate indemnity against such risk or
     liability is not reasonably assured to it.

         (iv)  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 8.02.  Notice of Default.  Within 90 days after the occurrence
                         ------------------                                     
of any default hereunder with respect to Securities of any series, the Trustee
shall transmit by mail to all Holders of Securities of such series entitled to
receive reports pursuant to Section 6.03(ii) notice of such default hereunder
known to the Trustee, unless such default shall have been cured or waived;
provided, however, that, except in the case of a default in the payment of the

any sinking fund installment with respect to Securities of such series the
Trustee shall be protected in withholding such notice if and so long as the
board of directors, the executive committee or a trust committee of directors
and/or Responsible Officers of the Trustee in good faith determines that the
withholding of such notice is in the interests of the Holders of Securities of
such series; and provided further that in the case of any default of the
                 -------- -------                                       
character specified in Section 7.01(iii) with respect to Securities of such
series, no such notice to Holders of Securities of such series shall be given
until at least 90 days after the occurrence thereof.  For the purpose of this
Section, the term "default", with respect to Securities of any series, means any
event which is, or after notice or lapse of time, or both, would become, an
Event of Default with respect to Securities of such series.

          SECTION 8.03.  Certain Rights of Trustee.  Except as otherwise

          (i) the Trustee may rely and shall be protected in acting or
     refraining from acting upon any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, note or other paper or document believed by it to be genuine and to
     have been signed or presented by the proper party or parties;

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

        (iii) whenever in the administration of this Indenture the Trustee shall
     deem it desirable that a matter be proved or established prior to taking,
     suffering or omitting any action hereunder, the Trustee (unless other
     evidence be herein specifically prescribed) may, in the absence of bad
     faith on its part, rely upon an Officers' Certificate;

         (iv) the Trustee may consult with counsel and the advice of such
     counsel or any Opinion of Counsel shall be full and complete authorization

          (v) the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request or direction
     of any of the Holders pursuant to this Indenture, unless such Holders shall

     costs, expenses and liabilities which might be incurred by it in compliance
     with such request or direction;

         (vi) the Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, security or other paper or document, but the Trustee, in its
     discretion, may make further inquiry or investigation into such facts or
     matters as it may see fit, and, if the Trustee shall determine to make such
     further inquiry or investigation, it shall be entitled to examine the
     books, records and premises of the Company, personally or by agent or
     attorney;

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

       (viii) the Trustee shall not be charged with knowledge of any default (as

     of Default shall have been given to the Trustee by the Company or any
     Holder; and

         (ix) the Trustee shall not be liable for any action taken, suffered or

                         -------------------------------------------------------

and neither the Trustee nor any Authenticating Agent assumes responsibility for
their correctness.  The

Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities.  The Trustee shall not be accountable for the
use or application by the Company of Securities or the proceeds thereof.

          SECTION 8.05.  May Hold Securities.  The Trustee, any Authenticating
                         --------------------                                 
Agent, any Paying Agent, the Security Registrar or any other agent of the
Company, in its individual or any other capacity, may become the owner or
pledgee of Securities and, subject to Sections 8.08 and 8.13, may otherwise deal
with the Company with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Security Registrar or such other agent.

          SECTION 8.06.  Money Held in Trust.  Money held by the Trustee in
                         --------------------                              
trust hereunder need not be segregated from other funds except to the extent
required by law.  The Trustee shall be under no liability for interest on any
money received by it hereunder except as otherwise agreed in writing with the
Company.

          SECTION 8.07.  Compensation and Reimbursement.  The Company agrees:
                         -------------------------------                     

          (i) 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);

         (ii) 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

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

                                                                              74

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

          When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 7.01, the expenses (including the
reasonable fees and expenses of its counsel) and the compensation for the
services are intended to constitute expenses of administration under any
applicable bankruptcy, insolvency or other similar law.

          The obligations of the Company set forth in this Section 8.07 and any
lien arising hereunder shall survive the resignation or removal of any Trustee,
the discharge of the Company's obligations pursuant to Article Eleven of this
Indenture and the termination of this Indenture and the repayment of the
Securities whether at the Stated Maturity or otherwise.

          SECTION 8.08.  Disqualification; Conflicting Interests.  If the
                         ----------------------------------------        
Trustee has or shall acquire a conflicting interest within the meaning of
Section 310 of the Trust Indenture Act, the Trustee shall either eliminate such
conflicting interest or resign, to the extent and in the manner provided by, and
subject to the provisions of, the Trust Indenture Act and this Indenture.  To
the extent permitted by the Trust Indenture Act, the Trustee shall not be deemed
to have a conflicting interest with respect to the Securities of any series by
virtue of being Trustee with respect to the Securities of any particular series
of Securities other than that series.

          SECTION 8.09.  Corporate Trustee Required; Eligibility.  There shall
                         ----------------------------------------

which shall be a corporation organized and doing business under the laws of the
United States of America, any State thereof or the District of Columbia,
authorized under such laws to exercise corporate trust powers, having a combined
capital and surplus of at least $5,000,000, subject to supervision or

organized and doing business under the laws of any other jurisdiction to serve
as trustee of an indenture qualified under the Trust Indenture Act, this Section
8.09 shall be automatically deemed amended to permit a corporation organized and
doing business under the laws of any such jurisdiction to serve as Trustee
hereunder.  If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of the aforesaid 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.
Neither the Company nor any person directly or indirectly controlling,
controlled by or under common control with the Company may serve as Trustee.  If
at any time the Trustee with respect to any series of Securities shall cease to
be eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

          SECTION 8.10.  Resignation and Removal; Appointment of Successor.  (i)
                         --------------------------------------------------   
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 8.11.

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

        (iii)  The Trustee may be removed with respect to any series of
Securities at any time 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.

         (iv)  If at any time:

          (a) the Trustee shall fail to comply with Section 8.08 with respect to
     any series of Securities after written request therefor by the Company or
     by any
<PAGE>
 
                                                                              76

     Holder who has been a bona fide Holder of a Security of such series for at
     least six months; or

          (b) the Trustee shall cease to be eligible under Section 8.09 with
     respect to any series of Securities and shall fail to resign after written
     request therefor by the Company or by any Holder of Securities of such
     series; or

          (c) the Trustee shall become incapable of acting with respect to any
     series of Securities 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, (1) the Company by a Board Resolution may remove the
Trustee with respect to such series, or (2) subject to Section 7.14, any Holder
who has been a bona fide Holder of a Security of such series for at least six
months may, on behalf of himself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee with respect to such series.

          (v)  If the Trustee shall resign, be removed or become incapable of
acting with respect to any series of Securities, or if a vacancy shall occur in
the office of Trustee with respect to any series of Securities for any cause,
the Company, by a Board Resolution, shall promptly appoint a successor Trustee
or Trustees with respect to the Securities of that or those series (it being
understood that any such successor Trustee may be appointed with respect to the
Securities of one or more or all of such series and that at any time there shall
be only one Trustee with respect to the Securities of any particular series) and
shall comply with the applicable requirements of Section 8.11.  If, within one
year after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to such series of Securities shall be
appointed by the 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 with respect to such series, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment, become the successor Trustee
with respect to

                                                                              77

such series and to that extent supersede the successor Trustee appointed by the
Company with respect to such series.  If no successor Trustee with respect to
such series shall have been so appointed by the Company or the Holders of
Securities of such series 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 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 such series.

         (vi)  The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
by mailing written notice of such event by first-class mail, postage prepaid, to
the Holders of Registered Securities of such series as their names and addresses
appear in the Security Register and, if Securities of such series are issuable
as Bearer Securities, by publishing notice of such event once in an Authorized
Newspaper in each Place of Payment located outside the United States.  Each
notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Principal Corporate Trust
Office.

          SECTION 8.11.  Acceptance of Appointment by Successor.  (i)  In the
                         ---------------------------------------             
case of the appointment hereunder of a successor Trustee with respect to any
series of Securities, every such successor Trustee so appointed shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, and thereupon the resignation or removal of the
retiring Trustee shall become effective with respect to all or any series as to
which it is resigning as Trustee, 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 with respect to all or any
such series; but, on request of the Company or such 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 such retiring Trustee with respect to all or any such series; and
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder with respect to all or any
such series.

         (ii)  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 (a) 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, (b)
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
(c) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates, subject nevertheless to its lien, if any,
provided for in Section 8.07.

        (iii)  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

                                                                              79

referred to in Paragraph (i) or (ii) of this Section, as the case may be.

         (iv)  No successor Trustee with respect to a series of Securities shall
accept its appointment unless at the time of such acceptance such successor
Trustee shall be qualified and eligible with respect to such series under this
Article.

          SECTION 8.12.  Merger, Conversion, Consolidation or Succession to
                         --------------------------------------------------
Business of Trustee.  Any corporation into which the Trustee may be merged or
- --------------------                                                         
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all of the
corporate trust business of the Trustee, shall be the successor of the Trustee
hereunder; provided that 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 8.13.  Preferential Collection of Claims Against Company.  If
                         --------------------------------------------------    
and when the Trustee shall be or become a creditor of the Company (or any other
obligor upon the Securities), the Trustee shall be subject to the provisions of
Section 311 of the Trust Indenture Act regarding the collection of such claims
against the Company (or any such other obligor).  A Trustee that has resigned or
been removed shall be subject to and comply with said Section 311 to the extent
required thereby.

          SECTION 8.14.  Appointment of Authenticating Agents.  The Trustee may
                         -------------------------------------                 
appoint an Authenticating Agent or Agents, which may include any Affiliate of
the Company, with respect to one or more series of Securities.  Such
Authenticating Agent or Agents at the option of the Trustee shall be authorized
to act on behalf of the Trustee to authenticate Securities of such series issued
upon original issuance, exchange, registration of transfer or partial redemption
thereof or pursuant to Section 3.06, and Securities so authenticated shall be
entitled to the

                                                                              80

benefits of this Indenture and shall be valid and obligatory for all purposes as
if authenticated by the Trustee hereunder.  Whenever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or the
Trustee's certificate of authentication or the delivery of Securities to the
Trustee for authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent,
a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent and delivery of Securities to the Authenticating Agent on
behalf of the Trustee.  Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business
under the laws of the United States of America, any State thereof or the
District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined capital and surplus of not less than $5,000,000 and subject to
supervision or examination by Federal or State authority.  Notwithstanding the
foregoing, an Authenticating Agent located outside the United States may be
appointed by the Trustee if previously approved in writing by the Company and if
such Authenticating Agent meets the minimum capitalization requirements of this
Section 8.14.  If such Authenticating Agent publishes reports of condition at
least annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published.  If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

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

          An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company.  The Trustee may at any time
(and upon request by the Company shall) terminate the agency of an
Authenticating Agent by giving written notice thereof to such Authenticating
Agent and to the Company.  Upon receiving such a notice of resignation or upon
such termination, or in case at any time such Authenticating Agent shall cease
to be eligible in accordance with the provisions of this Section, the Trustee
may appoint a successor Authenticating Agent which shall be acceptable to the
Company.  Any successor Authenticating Agent upon acceptance of its appointment
hereunder shall become vested with all the rights, powers and duties of its
predecessor hereunder, with like effect as if originally named as an
Authenticating Agent.  No successor Authenticating Agent shall be appointed
unless eligible under the provisions of this Section.

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

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

                                                                   , as Trustee,

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

exercise such Holder's option for repayment shall, as conditions to such
repayment, surrender the Security to be repaid in whole or in part together with
written notice of the exercise of such option at any office or agency of the
Company in a Place of Payment, not less than 30 nor more than 45 days prior to
the Repayment Date; provided, however, that surrender of Bearer Securities

in Section 5.02. Such notice, which shall be irrevocable, shall specify the
principal amount of such Security to be repaid, which shall be equal to the
minimum authorized denomination for such Security or an integral multiple
thereof, and shall identify the Security to be repaid and, in the case of a
partial repayment of the Security, shall specify the denomination or
denominations of the Security or Securities of the same series to be issued to
the Holder for the portion of the principal of the Security surrendered which is
not to be repaid.

          If any Bearer Security surrendered for repayment shall not be
accompanied by all unmatured coupons and all matured coupons in default, such
Bearer Security may be paid after deducting from the Repayment Price an amount
equal to the face amount of all such missing coupons, or the surrender of such
missing coupon or coupons may be waived by the Company and the Trustee if there
be furnished to them such security or indemnity as they may require to save each
of them and any Paying Agent harmless.  If thereafter the Holder of such Bearer
Security shall surrender to the Trustee or any Paying Agent any such missing
coupon in respect of which a deduction shall have been made from the Repayment
Price, such Holder shall be entitled to receive the amount so deducted without
interest thereon; provided, however, that interest represented by coupons shall

foregoing notice, in an aggregate principal amount equal to any portion of the

          The Company shall execute and the Trustee shall authenticate and
deliver without service charge to the Holder of any Bearer Security so
surrendered a new Registered Security or Securities or new Bearer Security or

authorized denomination or denominations specified in the foregoing notice, in
an aggregate principal amount equal to any portion of the principal of the
Security so surrendered which is not to be repaid; provided, however, that the

issuance of a Registered Security therefor shall be subject to applicable laws
and regulations, including provisions of the United States Federal income tax
laws and regulations in effect at the time of the exchange; neither the Company,
the Trustee nor the Security Registrar shall issue Registered Securities for
Bearer Securities if it has received an Opinion of Counsel that as a result of
such issuance the Company would suffer adverse consequences under the United
States Federal income tax laws then in effect and the Company has delivered to
the Trustee a Company Order directing the Trustee not to make such issuances
thereafter unless and until the Trustee receives a subsequent Company Order to
the contrary.  The Company shall deliver copies of such Company Order to the
Security Registrar.

requires, all provisions relating to the repayment of Securities shall relate,
in the case of any Security repaid or to be repaid only in part, to the portion

purchased in accordance with Section 14.04, on the Repayment Date become due and
payable at the price therein specified and from and after the Repayment Date
such Securities shall cease to bear interest and shall be paid on the Repayment
Date, and the coupons for such interest appertaining to Bearer Securities so to
be repaid, except to the extent provided above, shall be void, unless the
Company shall default in the payment of such price, in which case the Company
shall continue to be obligated for the principal amount of such Securities and
shall be obligated to pay interest on such principal amount at the rate
prescribed therefor by such Securities from time to time until payment in full

          (a) Notwithstanding any other provisions of this Indenture, the
Trustee may make such reasonable regulations as it may deem advisable for any
meeting of Holders of Securities of such series in regard to proof of the
holding of Securities of such series and of the appointment of proxies and in
regard to the appointment and duties of inspectors of votes, the submission and
examination of proxies, certificates and other evidence of the right to vote,
and such other matters concerning the conduct of the meeting as it shall deem
appropriate.  Except as otherwise permitted or required by any such regulations,
the holding of Securities shall be proved in the manner specified in Section
1.04 and the appointment of any proxy shall be proved in the manner specified in
Section 1.04 or, in the case of Bearer Securities, by having the signature of
the person executing the proxy witnessed or guaranteed by any trust company,
bank or banker authorized by Section 1.04 to certify to the holding of Bearer

proxies, regular on their face, may be presumed valid and genuine without the
proof specified in Section 1.04 or other proof.

          (b) The Trustee shall, by an instrument in writing, appoint a
temporary chairperson of the meeting, unless the meeting shall have been called
by the Company or by Holders of Securities as provided in Section 15.02(ii), 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
chairperson.  A permanent chairperson and a permanent secretary of the meeting

Securities of such series held or represented by him; provided, however, that no

          (d) Any meeting of Holders of Securities of any series duly called
pursuant to Section 15.02 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.

any series shall be by written ballots on which shall be subscribed the
signatures of the Holders of Securities of such series or of their
representatives by proxy and the principal amounts and serial numbers of the
Outstanding Securities of such series held or represented by them.  The
permanent chairperson of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in triplicate of all votes cast at the meeting.  A record, at least in
triplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 15.02 and, if
applicable, Section 15.04. Each copy shall be signed and verified by the
affidavits of the permanent chairperson 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.

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

          SECTION 1.04.  Acts of Holders.  (i) Any request, demand,
                         ----------------      
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Holders or Holders of any series may be
embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Holders in person or by an agent duly appointed in writing.
If Securities of a series are issuable in whole or in part as Bearer Securities,
any request, demand, authorization, direction, notice, consent, waiver or other
action provided by this Indenture to be given or taken by Holders may,
alternatively, be embodied in and evidenced by the record of Holders of
Securities voting in favor thereof, either in person or by proxies duly
appointed in writing, at any meeting of Holders of Securities duly called and
held in accordance with the provisions of Article Sixteen 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 the holding by any
Person of a Security, shall be sufficient for any purpose of this Indenture and
(subject to Section 8.01) 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 16.06.

         (ii)  The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by the certificate of any notary public or other officer authorized
by law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by or on behalf of any legal entity other than an individual, such
certificate or affidavit shall also constitute proof of the 
<PAGE>
 
                                                                              15

authority of the Person executing the same. The fact and date of the execution
of any such instrument or writing, or the authority of the Person executing the
same, may also be proved in any other manner which the Trustee deems sufficient.

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

         (iv)  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, as depositary, by any
trust company, bank or other depositary, wherever situated, if such certificate
shall be deemed by the Trustee to be satisfactory, showing that at the date
therein mentioned such Person had on deposit with such 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, or (2) such Bearer Security
is produced to the Trustee by some other Person, or (3) such Bearer Security is
surrendered in exchange for a Registered Security, or (4) such Bearer Security
is no longer Outstanding.

          (v)  The fact and date of execution of any such instrument or writing,
the authority of the Person executing the same and the principal amount and
serial numbers of Bearer Securities held by the Person so executing such
instrument or writing and the date of holding the same may also be proved in any
other manner which the Trustee deems sufficient; and the Trustee may in any
instance require further proof with respect to any of the matters referred to in
this Section.

         (vi)  Any request, demand, authorization, direction, notice, consent,
waiver or other action by the Holder of any Security shall bind every future
Holder of the same Security and the Holder of every Security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof, in
respect of any action taken, suffered or omitted by the Trustee or the Company
in reliance 
<PAGE>
 
                                                                              16

thereon, whether or not notation of such action is made upon such Security.

        (vii)  For purposes of determining the principal amount of Outstanding
Securities of any series the Holders of which are required, requested or
permitted to give any request, demand, authorization, direction, notice,
consent, waiver or take any other Act under the Indenture, each Security
denominated in a Foreign Currency or composite currency shall be deemed to have
the principal amount determined by the Exchange Rate Agent by converting the
principal amount of such Security in the currency in which such Security is
denominated into Dollars at the Exchange Rate as of the date such Act is
delivered to the Trustee and, where it is hereby expressly required, to the
Company, by Holders of the required aggregate principal amount of the
Outstanding Securities of such series (or, if there is no such rate on such
date, such rate on the date determined as specified as contemplated in Section
3.01).

       (viii)  The Company may, in the circumstances permitted by the Trust
Indenture Act, set a record date for purposes of determining the identity of
Holders of Securities of any series entitled to give any request, demand,
authorization, direction, notice, consent, waiver or take any other Act, or to
vote or consent to any action by vote or consent authorized or permitted to be
given or taken by Holders of Securities of such series.  If not set by the
Company prior to the first solicitation of a Holder of Securities of such Series
made by any Person in respect of any such action, or in the case of any such
vote, prior to such vote, such record date shall be the later of 30 days prior
to the first solicitation of such consent or the date of the most recent list of
Holders of such Securities furnished to the Trustee pursuant to Section 6.01
prior to such solicitation.

         (ix)  Without limiting the foregoing, a Holder entitled hereunder to
take any action hereunder with regard to any particular Security may do so with
regard to all or any part of the principal amount of such Security or by one or
more duly appointed agents each of which may do so pursuant to such appointment
with regard to all or any part of such principal amount. Any notice given or
action taken by a Holder or its agents with regard to different parts of such
principal amount pursuant to this paragraph shall have the same effect as if
given or taken by separate Holders of each such different part.

                                                                              17

          (x)  Without limiting the generality of the foregoing, unless
otherwise specified pursuant to Section 3.01 or pursuant to one or more
indentures supplemental hereto, a Holder, including a Depositary that is the
Holder of a Global Security, may make, give or take, by a proxy or proxies duly
appointed in writing, any request, demand, authorization, direction, notice,
consent, waiver or other action provided in this Indenture to be made, given or
taken by Holders, and a Depositary that is the Holder of a Global Security may
provide its proxy or proxies to the beneficial owners of interests in any such
Global Security through such Depositary's standing instructions and customary
practices.

          (xi)  The Company may fix a record date for the purpose of determining
the Persons who are beneficial owners of interests in any Global Security held
by a Depositary entitled under the procedures of such Depositary to make, give
or take, by a proxy or proxies duly appointed in writing, any request, demand,
authorization, direction, notice, consent, waiver or other action provided in
this Indenture to be made, given or taken by Holders. If such a record date is
fixed, the Holders on such record date or their duly appointed proxy or proxies,
and only such Persons, shall be entitled to make, give or take such request,
demand, authorization, direction, notice, consent, waiver or other action,
whether or not such Holders remain Holders after such record date. No such
request, demand, authorization, direction, notice, consent, waiver or other
action shall be valid or effective if made, given or taken more than 90 days
after such record date.

          SECTION 1.05.  Notices, etc., to Trustee and Company.  Any request,
                         --------------------------------------  
demand, authorization, direction, notice, consent, waiver or Act of Holders or
other document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with,

          (i)  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 Principal Corporate Trust Office, or

         (ii)  the Company by any Holder or by the Trustee shall be sufficient
for every purpose hereunder (unless otherwise herein expressly provided) if in
writing and mailed, first-class, postage prepaid, to the Company, to the
attention of its Treasurer, addressed to it at the address 
<PAGE>
 
                                                                              18

of its principal office specified in the first paragraph of this Indenture or at
any other address previously furnished in writing to the Trustee by the Company.

          SECTION 1.06.  Notices to Holders; Waiver.  Where this Indenture or
                         ---------------------------
any Security provides for notice to Holders of any event,

          (1)  such notice shall be sufficiently given (unless otherwise herein
     or in such Security expressly provided) if in writing and mailed, first-
     class, postage prepaid, to each Holder of Registered Securities 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.

          (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, if the Securities of such series are then listed on The International
     Stock Exchange of the United Kingdom and the Republic of Ireland Limited
     and such stock exchange shall so require, in London and, if the Securities
     of such series are then listed on the Luxembourg Stock Exchange and such
     stock exchange shall so require, in Luxembourg and, if the Securities of
     such series are then listed on any other stock exchange and such stock
     exchange shall so require, in any other required city outside the United
     States, or, if not practicable, elsewhere in Europe 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.

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 Registered Securities shall affect
the sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice by publication to Holders of Bearer
Securities given as provided above.
<PAGE>
 
                                                                              19

          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 mailed to
Holders of Registered Securities as provided above.

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

          SECTION 1.07.  Language of Notices, Etc.  Any request, demand,
                         -------------------------                      
authorization, direction, notice, consent, or waiver required or permitted under
this Indenture shall be in the English language, except that any published
notice may be in an official language of the country of publication.

          SECTION 1.08.  Conflict with Trust Indenture Act.  If and to the
                         ----------------------------------
extent that any provision of this Indenture limits, qualifies or conflicts with
the duties imposed by, or with another provision (an "incorporated provision")
included in this Indenture by operation of Sections 310 and 318, inclusive, of
the TIA, such imposed duties or incorporated provision shall control.

          SECTION 1.09.  Effect of Headings and Table of Contents.  The Article
                         -----------------------------------------
and Section headings herein and the Table of Contents are for convenience only
and shall not affect the construction hereof.

                         -----------------------
in this Indenture by the Company shall bind its successors and assigns, whether
so expressed or not.

          SECTION 1.11.  Separability Clause.  In case any provision in this

Indenture or in the Securities shall be invalid, illegal or unenforceable, the

                         ----------------------
the Securities, express or implied, shall give to any Person, other than the
parties hereto and their successors hereunder, the Holders and, to the extent
provided in Article Fourteen hereof, the holders of Senior Indebtedness and
creditors in respect of General Obligations, any benefit or any legal or
equitable right, remedy or claim under this Indenture.

Date, Stated Maturity, Repayment Date or Redemption Date of any Security or any
date on which any Defaulted Interest is proposed to be paid shall not be a
Business Day at any Place of Payment, then (notwithstanding any other provisions
of the Securities or this Indenture) payment of the principal of, premium, if
any, or interest on any Securities need not be made at such Place of Payment on
such date, but may be made on the next succeeding Business Day with the same
force and effect as if made on the Interest Payment Date, Stated Maturity,
Repayment or Redemption Date or on the date on which Defaulted Interest is
proposed to be paid and, if such payment is made, no interest shall accrue on
such payment for the period from and after any such Interest Payment Date,
Stated Maturity, Repayment Date or Redemption Date or date on which Defaulted
Interest is proposed to be paid, as the case may be.

          SECTION 1.14.  Governing Law.  This Indenture and the Securities shall

Securities may be manual or facsimile. Coupons shall bear the facsimile
signature of the Company's Chairman of the Board, its President, a Vice Chairman
of the Board or one of its Vice Presidents.

          Securities and coupons 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 shall, upon receipt of the Company
Order, authenticate and deliver such Securities as in this Indenture provided
and not otherwise; provided, however, that, in connection with its original
                   --------  -------                                       
issuance, no Bearer Security shall be mailed or otherwise delivered to any
location in the United States; and provided further that a Bearer Security may
                                   ----------------                           
be delivered in connection with its original issuance only if the Person
entitled to receive such Bearer Security shall have delivered to the Trustee, or
such other Person as shall be specified in a temporary Global Security delivered
pursuant to Section 3.04, a certificate in the form required by Section 3.11(i).

     If the Company shall establish pursuant to Section 3.01 that the Securities
of a series are to be issued in whole or in part in the form of one or more
Global Securities in registered or permanent bearer form, then the Company shall
execute and the Trustee shall, in accordance with this Section and a Company
Order for the authentication and delivery of such Global Securities with respect
to such series, authenticate and deliver one or more Global Securities in
permanent or temporary form that (i) shall represent and shall be denominated in
an aggregate amount equal to the aggregate principal amount of the Outstanding
Securities of such series to be represented by one or more Global Securities,
(ii) shall be registered, if in registered form, in the name of the Depositary
for such Global Security or Securities or the nominee of such Depositary and
(iii) shall be delivered by the Trustee to
<PAGE>
 
                                                                            28

such Depositary or pursuant to such Depositary's instructions.

          Each Depositary designated pursuant to Section 3.01 for a Global
Security in registered form must, at the time of its designation and at all
times while it serves as Depositary, be a clearing agency registered under the
Exchange Act, and any other applicable statute or regulation.

          In authenticating such Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and (subject to Section 8.01) shall be
fully protected in relying upon, an Opinion of Counsel complying with Section
1.02 and stating that,

          (i)  the form of such Securities and coupons, if any, has been
     established in conformity with the provisions of this Indenture;

         (ii)  the terms of such Securities and coupons, if any, or the manner
     of determining such terms have been established in conformity with the
     provisions of this Indenture;

        (iii)  that such Securities and coupons, 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 against the Company in accordance with their terms, subject to
     bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
     other laws of general applicability relating to or affecting the
     enforcement of creditors' rights and to general principles of equity; and

         (iv)  such other matters as the Trustee may reasonably request.

          The Trustee shall not be required to authenticate such Securities if
the issue thereof will adversely affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

                                                                             29

          Notwithstanding the provisions of Section 3.01 and of this Section
3.03, if all Securities of a series are not to be originally issued at one time,
it shall not be necessary to deliver the Board Resolution or Officers'
Certificate otherwise required pursuant to Section 3.01 or the Company Order and
Opinion of Counsel otherwise required pursuant to this Section 3.03 at or prior
to the time of authentication of each Security of such series if such documents
are delivered at or prior to the authentication upon original issuance of the
first Security of such series to be issued and such documents reasonably
contemplate the issuance of all Securities of such series; provided that any
                                                           --------
subsequent request by the Company to the Trustee to authenticate Securities of
such series upon original issuance shall constitute a representation and
warranty by the Company that as of the date of such request, the statements made
in the Officers' Certificate or other certificates delivered pursuant to
Sections 1.02 and 3.01 shall be true and correct as if made on such date.

          A Company Order, Officers' Certificate or Board Resolution or
supplemental indenture delivered by the Company to the Trustee in the
circumstances set forth in the preceding paragraph may provide that Securities
which are the subject thereof will be authenticated and delivered by the Trustee
or its agent on original issue from time to time in the aggregate principal
amount, if any, established for such series pursuant to such procedures
acceptable to the Trustee as may be specified from time to time by Company Order
upon the telephonic, electronic or written order of Persons designated in such
Company Order, Officers' Certificate, supplemental indenture or Board Resolution
and that such Persons are authorized to determine, consistent with such Company
Order, Officers' Certificate, supplemental indenture or Board Resolution, such
terms and conditions of said Securities as are specified in such Company Order,
Officers' Certificate, supplemental indenture or Board Resolution.

          Each Registered Security shall be dated the date of its
authentication; and unless otherwise specified as contemplated by Section 3.01,
each Bearer Security and any temporary Global Security referred to in Section
3.04 shall be dated as of the date of original issuance of such Security.

          No Security or coupon appertaining thereto shall be entitled to any
benefit under this Indenture or be valid 
<PAGE>
 
                                                                             30

or obligatory for any purpose, unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder. Except as permitted by
Section 3.06, the Trustee shall not authenticate and deliver any Bearer Security
unless all appurtenant coupons for interest then matured have been detached and
canceled. Notwithstanding the foregoing, if any Security or portion thereof
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 cancelation as provided in Section 3.09 together with a written statement
(which need not comply with Section 1.02 and need not be accompanied by an
Opinion of Counsel) stating that such Security or portion thereof 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 3.04.  Temporary Securities.  (a)  Pending the preparation of
                         ---------------------                                 
definitive Securities of any series, the Company may execute, and upon Company
Order and the receipt of the certifications and opinions required under Sections
3.01 and 3.03, the Trustee shall authenticate and deliver, temporary Securities
which are printed, lithographed, typewritten, mimeographed or otherwise
produced, in any authorized denominations, 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.  In the case of any series which may be issuable
as Bearer Securities, such temporary Securities may be in global form,
representing such of the Outstanding Securities of such series as shall be
specified therein.

          (b)  Unless otherwise provided pursuant to Section 3.01:

          (i)  Except in the case of temporary Securities in global form, each
     of which shall be exchanged in accordance with the provisions of the
     following 
<PAGE>
 
                                                                            31

     paragraphs, if temporary Securities of any series are issued, the Company
     will cause definitive Securities of such series to be prepared without
     unreasonable delay. After the preparation of definitive Securities, the
     temporary Securities of such series shall be exchangeable for definitive
     Securities of such series upon surrender of the temporary Securities of
     such series at the office or agency of the Company in a Place of Payment
     for that series, without charge to the Holder. Upon surrender for
     cancelation of any one or more temporary Securities of any series
     (accompanied, if applicable, by all unmatured coupons and all matured
     coupons in default appertaining thereto), the Company shall execute and the
     Trustee shall authenticate and deliver in exchange therefor a like
     principal amount of definitive Securities of such series of authorized
     denominations; provided, however, that no definitive Bearer Security shall
                    --------  -------                                          
     be delivered in exchange for a temporary Registered Security; and provided
                                                                       --------
     further that a definitive Bearer Security shall be delivered in exchange
     -------                                                                 
     for a temporary Bearer Security only in compliance with the conditions set
     forth in Section 3.03. Until so exchanged, the temporary Securities of any
     series shall in all respects be entitled to the same benefits under this
     Indenture as definitive Securities of such series.

         (ii)  If temporary Securities of any series are issued in global form,
     any such temporary Global Security shall, unless otherwise provided in such
     temporary Global Security, be delivered to the London office of a
     depositary or common depositary (the "Common Depositary"), for the benefit
     of the operator of Euroclear and 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). Upon receipt of written instructions (which
     need not comply with Section 1.02) signed on behalf of the Company by any
     Person authorized to give such instructions, the Trustee or any
     Authenticating Agent shall endorse such temporary Global Security to
     reflect the initial principal amount, or an increase in the principal
     amount, of Outstanding Securities represented thereby. Until such initial
     endorsement, such temporary Global Security shall not evidence any
     obligation of the Company. Such temporary Global Security shall at any time
     represent the aggregate principal amount of Outstanding Securities
     theretofore 
<PAGE>
 
                                                                             32

     endorsed thereon as provided above, subject to reduction to reflect
     exchanges as described below.

        (iii)  Unless otherwise specified in such temporary Global Security, and
     subject to the second proviso in the following paragraph, the interest of a
     beneficial owner of Securities of a series in a temporary Global Security
     shall be exchanged for definitive Securities including a definitive Global
     Bearer Security) of such series and of like tenor following the Global
     Exchange Date (as defined below) when the account holder instructs
     Euroclear or CEDEL S.A., as the case may be, to request such exchange on
     his behalf and delivers to Euroclear or CEDEL S.A., as the case may be, a
     certificate in the form required by Section 3.11(i), dated no earlier than
     15 days prior to the Global Exchange Date, copies of which certificate
     shall be available from the offices of Euroclear and CEDEL S.A., the
     Trustee, any Authenticating Agent appointed for such series of Securities
     and each Paying Agent. 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
     Euroclear or CEDEL S.A. Definitive Securities in bearer form to be
     delivered in exchange for any portion of a temporary Global Security shall
     be delivered only outside the United States.

         (iv)  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 as the "Global Exchange Date" (the "Global
     Exchange Date"), the Company shall deliver to the Trustee, or, if the
     Trustee appoints an Authenticating Agent pursuant to Section 8.14, to any
     such Authenticating Agent, definitive Securities in aggregate principal
     amount equal to the principal amount of such temporary Global Security,
     executed by the Company. Unless otherwise specified as contemplated by
     Section 3.01, such definitive Securities shall be in the form of Bearer
     Securities or Registered Securities, or any combination thereof, as may be
     specified by the Company, the Trustee or any such Authenticating Agent, as
     may be appropriate. On or after the Global Exchange Date, such temporary
     Global Security shall be surrendered by the Common Depositary to the
     Trustee or any

                                                                            33

     such Authenticating Agent, 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 or any such Authenticating Agent 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,
     which, except as otherwise specified as contemplated by Section 3.01, shall
     be in the form of Bearer Securities or Registered Securities, or any
     combination thereof; provided, however, that unless otherwise specified in
                          --------  -------
     such temporary Global Security, upon such presentation by the Common
     Depositary, such temporary Global Security is accompanied by a certificate
     dated the Global Exchange Date or a subsequent date and signed by Euroclear
     as to the portion of such temporary Global Security held for its account
     then to be exchanged and a certificate dated the Global Exchange Date or a
     subsequent date and signed by CEDEL S.A., as to the portion of such
     temporary Global Security held for its account then to be exchanged, each
     in the form required by Section 3.11(ii); and provided further that a
                                                   ----------------  
     definitive Bearer Security (including a definitive global Bearer Security)
     shall be delivered in exchange for a portion of a temporary Global Security
     only in compliance with the conditions set forth in Section 3.03.

          (v)  Upon any exchange of a portion of any such temporary Global
     Security, such temporary Global Security shall be endorsed by the Trustee
     or any such Authenticating Agent, as the case may be, to reflect the
     reduction of the principal amount evidenced thereby, whereupon its
     remaining principal amount shall be reduced for all purposes by the amount
     so exchanged. Until so exchanged in full, such temporary Global Security
     shall in all respects be entitled to the same benefits under this Indenture
     as definitive Securities of such series authenticated and delivered
     hereunder, except that, unless otherwise specified as contemplated by
     Section 3.01, interest payable on such temporary Global Security on an
     Interest Payment Date for

     Securities of such series occurring prior to the applicable Global Exchange
     Date shall be payable, without interest, to Euroclear and CEDEL S.A. on or
     after such Interest Payment Date upon delivery by Euroclear and CEDEL S.A.
     to the Trustee or the Paying Agent, as the case may be, of a certificate or
     certificates in the form required by Section 3.11(iii), for credit 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 Euroclear or CEDEL
     S.A., as the case may be, a certificate in the form required by Section
     3.11(iv). Any interest so received by Euroclear and CEDEL S.A. and not paid
     as herein provided prior to the Global Exchange Date shall be returned to
     the Trustee or Paying Agent, as the case may be, which, upon expiration of
     two years after such Interest Payment Date, shall repay such interest on
     Company Request in accordance with Section 5.03.

          SECTION 3.05. Registration, Registration of Transfer and Exchange.  
                        ---------------------------------------------------- 
With respect to Registered Securities, the Company shall keep or cause to be
kept a register (sometimes 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 Registered Securities and the registration of
transfers of Registered Securities and the Company shall appoint a "Security
Registrar", and may appoint any "Co-Security Registrar", as may be appropriate,
to keep the Security Register. Such Security Register shall be in written form
or in any other form capable of being converted into written form within a
reasonable time. At all reasonable times the information contained in such
Security Register shall be available for inspection by the Trustee at the office
of the Security Registrar. In the event that any Registered Securities issued
hereunder have the City of New York as a Place of Payment, the Company shall
appoint either a Security Registrar or Co-Security Registrar located in the City
of New York.

          Upon surrender for registration of transfer of any Registered Security
of any series at the office or agency of the Company maintained pursuant to
Section 5.02 for such purpose in a Place of Payment for such series, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or 
<PAGE>
 
                                                                              35

transferees, one or more new Registered Securities of such series of any
authorized denominations and of a like aggregate principal amount, tenor and
Stated Maturity.

          At the option of the Holder, Registered Securities of any series may
be exchanged for other Registered Securities of such series, of any authorized
denominations and of like aggregate principal amount, tenor and Stated Maturity,
upon surrender of the Securities to be exchanged at such office or agency.
Whenever any Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities which
The Holder making the exchange is entitled to receive.

          Registered Securities may not be exchanged for Bearer Securities.

          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 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 in an amount equal to the face amount of such missing coupon or
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there be furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless.  If
thereafter the Holder of such Security shall surrender to any Paying Agent any
such missing coupon in respect of which such a payment shall have been made,
such Holder shall be entitled to receive the amount of any such payment from the
Company; provided, however, that interest represented by coupons shall be
         --------  -------                                               
payable only upon presentation and surrender of those coupons at an office or
agency of a Paying Agent, maintained pursuant to Section 5.02 for such purpose,
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 like tenor after the
close of business at such office or agency on (i) any Regular Record Date and
before the opening of business at such office or agency on the relevant Interest
Payment Date, 
<PAGE>
 
                                                                              36

or (ii) any Special Record Date and before the opening of business at such
office or agency on the related date for payment of Defaulted Interest, such
Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be.

          Notwithstanding any other provision of this Section, unless and until
it is exchanged in whole or in part for individual Securities represented
thereby, a Global Security representing all or a portion of the Securities of a
series may not be transferred except as a whole by the Depositary for such
series to a nominee of such Depositary or by a nominee of such Depositary to
such Depositary or another nominee of such Depositary or by such Depositary or
any such nominee to a successor Depositary for such series or a nominee of such
successor Depositary.

          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.

          If at any time the Depositary for the Securities of a series notifies
the Company that it is unwilling or unable to continue as Depositary for the
Securities of such series or if at any time the Depositary for the Securities of
such series shall no longer be eligible under Section 3.03, the Company shall
appoint a successor Depositary with respect to the Securities of such series. If
a successor Depositary for the Securities of such series is not appointed by the
Company within 90 days after the Company receives such notice or becomes aware
of such ineligibility, the Company's election pursuant to Section 3.01(vi) shall
no longer be effective with respect to the Securities of such series and the
Company will execute, and the Trustee, upon receipt of a Company Order for the
authentication and delivery of definitive Securities of such series, will
authenticate and deliver Securities of such series of like tenor and terms in
definitive form in an aggregate principal amount equal to the principal amount
of the Global Security or Securities representing such series in exchange for
such Global Security or Securities.

          The Company may at any time and in its sole discretion determine that
the Securities of any series issued in the form of one or more Global Securities
shall no longer be represented by such Global Security or Securities. 
<PAGE>
 
                                                                              37

In such event, 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 deliver, Securities of such series of like tenor and terms in
definitive form in an aggregate principal amount equal to the principal amount
of the Global Security or Securities representing such series in exchange for
such Global Security or Securities.

          If specified by the Company pursuant to Section 3.01 with respect to a
series of Securities, the Depositary for such series of Securities may surrender
a Global Security for such series of Securities in exchange in whole or in part
for Securities of such series of like tenor and terms and in definitive form on
such terms as are acceptable to the Company, the Trustee and such Depositary.
Thereupon, the Company shall execute, and the Trustee upon receipt of a Company
Order for the authentication and delivery of definitive Securities of such
series, shall authenticate and deliver, without service charge:

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

          (b)  to such Depositary a new Global Security of like tenor and terms
     and in an authorized denomination equal to the difference, if any, between
     the principal amount of the surrendered Global Security and the aggregate
     principal amount of Securities delivered to Holders thereof.

          In any exchange provided for in any of the preceding three paragraphs,
the Company will execute and the Trustee, pursuant to a Company Order, will
authenticate and deliver, Securities (a) in definitive registered form in
authorized denominations, if the Securities of such series are issuable as
Registered Securities, (b) in definitive bearer form in authorized
denominations, with coupons attached, if the Securities of such series are
issuable as Bearer Securities or (c) as either Registered or Bearer Securities,
if the Securities of such series are issuable in either form; provided, however,
                                                              --------  ------- 
that no definitive Bearer Security shall be delivered in exchange for a

Global Security other than in accordance with the provisions of Sections 3.03
and 3.04.

          Upon the exchange of Global Securities for Securities in definitive
form, such Global Securities shall be canceled by the Trustee. Registered
Securities issued in exchange for a Global Security pursuant to this Section
3.05 shall be registered in such names and in such authorized denominations, and
delivered to such addresses, as the Depositary for such Global Security,
pursuant to instructions from its direct or indirect participants or otherwise,
shall instruct the Trustee in writing. The Trustee shall deliver such Registered
Securities to the Persons in whose names such Securities are so registered or to
the Depositary. The Trustee shall deliver Bearer Securities issued in exchange
for a Global Security pursuant to this Section 3.05 to the Depositary or to the
Persons at such addresses, and in such authorized denominations, as the
Depositary for such Global Security, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee in writing;
provided, however, that no definitive Bearer Security shall be delivered in
- --------  -------                                                          
exchange for a temporary Global Security other than in accordance with the
provisions of Sections 3.03 and 3.04.

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

          Every Security presented or surrendered for registration of transfer
or exchange shall (if so required by the Company or the Security Registrar) 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.

          Unless otherwise provided in the Securities to be registered for
transfer or exchanged, no service charge shall be made for any registration of
transfer or exchange of Securities, but the Company may (unless otherwise
provided in such Securities) require payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in connection with any
registration of 
<PAGE>
 
                                                                              39

transfer or exchange of Securities, other than exchanges expressly provided in
this Indenture to be made at the Company's own expense or without expense or
without charge to Holders.

          Neither the Company, the Security Registrar nor any Co-Security
Registrar shall be required (i) to issue, register the transfer of or exchange
any Securities of any series during a period beginning at the opening of
business 15 days before the day of selection of Securities of such series to be
redeemed and ending 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 of Registered Securities of such series so
selected for redemption or (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 or exchange of any Securities or
portions thereof so selected for redemption.

          Notwithstanding anything herein to the contrary, the exchange of
Bearer Securities into Registered Securities shall be subject to applicable laws
and regulations in effect at the time of exchange; none of the Company, the
Trustee nor the Security Registrar shall exchange any Bearer Securities into
Registered Securities if it has received an Opinion of Counsel that as a result
of such exchanges the Company would suffer adverse consequences under the United
States federal income tax laws and regulations then in effect and the Company
has delivered to the Trustee a Company Order directing the Trustee not to make
such exchanges unless and until the Trustee receives a subsequent Company Order
to the contrary. The Company shall deliver copies of such Company Orders to the
Security Registrar.

                         ------------------------------------------------- 
(i) any mutilated Security or Security with a mutilated coupon is surrendered to
the Trustee or the Security Registrar, or if the Company, the Trustee and the
Security Registrar receive evidence to their satisfaction of the destruction,

Company, the Trustee or the Security Registrar that such Security has been
acquired by a bona fide purchaser, the Company shall execute and upon its
request the Trustee shall authenticate and deliver, in lieu of any such
mutilated, destroyed, lost or stolen Security or in exchange for the Security to
which a mutilated, destroyed, lost or stolen coupon appertains (with all
appurtenant coupons not mutilated, destroyed, lost or stolen), a new Security of
the same series and Stated Maturity and of like tenor and principal amount,
bearing a number not contemporaneously outstanding and, if applicable, with
coupons corresponding to the coupons appertaining thereto; provided, however ,
                                                           --------  ------- 
that any new Bearer Security will be delivered only in compliance with the
conditions set forth in Section 3.05.

          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; provided,
                                                                      --------
however, that payment of principal of (and premium, if any) and any interest on

Bearer Securities shall be payable only at an office or agency located outside
the United States, and, in the case of interest, unless otherwise specified as
contemplated by Section 3.01, only upon presentation and surrender of the
coupons appertaining thereto.

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

          Every new Security of any series, with its coupons, if any, issued
pursuant to this Section in exchange for any mutilated Security or in lieu of
any destroyed, lost or stolen Security, or in exchange for a Security with a
mutilated, destroyed, lost or stolen coupon, shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Security and its coupons, if any, or the mutilated,
destroyed, lost or stolen coupon shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of the same series 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 3.07.  Payment of Interest; Interest Rights Preserved.  Unless
                         -----------------------------------------------        
otherwise provided as contemplated by Section 3.01, interest on any Registered
Security which is payable, and is punctually paid or duly provided for, on any
Interest Payment Date shall unless otherwise provided in such Security 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.  Unless otherwise specified as contemplated by Section 3.01,
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 referred to in Section 3.05) 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.  At the option of
the Company, payment of interest on any Registered Security may be made by check
in the currency designated for such payment pursuant to the terms of such
Registered Security mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register or by wire transfer to an account
in such currency designated by such Person in writing not later than ten days
prior to the date of such payment.

          Any interest on any Registered Security 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 his having been such Holder,
and such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (i) or clause (ii) below.

          (i)  The Company may elect to make payments of any Defaulted Interest
to the Persons in whose names any such Registered Securities (or their
respective Predecessor Securities) are registered at the close of business on a

Special Record Date for the payment of such Defaulted Interest, which shall be
fixed in the following manner. The Company shall 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 Interest which shall be not more than 15 nor 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 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 mailed as aforesaid, such Defaulted Interest shall be
paid to the Persons in whose names such Registered Securities (or their
respective Predecessor Securities) are registered on such Special Record Date
and shall no longer be payable pursuant to the following clause (ii). In case a
Bearer Security of any series is surrendered at the office or agency in a Place
of Payment for such series in exchange for a Registered Security of such series
after the close of business at such office or agency on any Special Record Date
and before the opening of business at such office or agency on the related
proposed date of payment of Defaulted Interest, such Bearer Security shall be
surrendered without the coupon relating to such proposed date for payment and
Defaulted Interest will not be payable on such proposed date for payment 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.

          (ii)  The Company may make payment of any Defaulted Interest in any
other lawful manner not inconsistent with the requirements of any securities

exchange on which the Securities with respect to which there exists such default
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 payment shall be deemed practicable by the
Trustee.

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

          Subject to the limitations set forth in Section 5.02, the Holder of
any coupon appertaining to a Bearer Security shall be entitled to receive the
interest payable on such coupon upon presentation and surrender of such coupon
on or after the Interest Payment Date of such coupon at an office or agency
maintained for such purpose pursuant to Section 5.02.

                         ----------------------
any coupons appertaining thereto and any temporary Global Security shall pass by
delivery.

          Prior to due presentment for registration of transfer of any
Registered Security, the Company, the Trustee and any agent of the Company or
the Trustee may treat the Person in whose name such Security is registered as
the owner of such Security for the purpose of receiving payment of principal of,
premium, if any, and (subject to Section 3.07) interest on such Security, and
for all purposes whatsoever, whether or not such Security be overdue, and
neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.

          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 Security or coupon for the purpose of receiving payment
thereof or on account thereof and for all other purposes whatsoever whether or
not such 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.

          SECTION 3.12.  Judgments.  The Company may provide, pursuant to
                         ---------- 
Section 3.01, for the Securities of any series that, to the fullest extent
possible under applicable law and except as may otherwise be specified as
contemplated in Section 3.01, (a) the obligation, if any, of the Company to pay
the principal of (and premium, if any) and interest of the Securities of any
series and any appurtenant coupons in a Foreign Currency, composite currency or
Dollars (the "Designated Currency") as may be specified pursuant to Section 3.01

due as a separate and independent obligation and, until discharged as provided
herein, shall continue in full force and effect.

                            Redemption of Securities
                            ------------------------

          SECTION 4.01.  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 3.01 for Securities of any series, in accordance with this Article.

          SECTION 4.02.  Election To Redeem; Notice to Trustee.  The election of
                         --------------------------------------
the Company to redeem any Securities redeemable at the option of the Company
shall be evidenced by an Officers' Certificate. In case of any redemption at the
election of the Company of less than all the Securities of any series, the
Company shall, at least 60 days prior to the Redemption Date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee and the Security Registrar of such Redemption Date and of the
principal amount of Securities of such series to be redeemed. In the case of any
redemption of Securities (i) prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, or (ii) pursuant to an election of the Company which is subject to a
condition specified in the terms of such Securities, the Company shall furnish
the Trustee with an Officers' Certificate evidencing compliance with such
restriction.

          SECTION 4.03.  Selection by Security Registrar of Securities To Be
                         ---------------------------------------------------
Redeemed.  If less than all the Securities of any series with the same 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 Security Registrar from
the Outstanding Securities of such series having such terms not previously
called for redemption, by such method as the Security Registrar shall 
<PAGE>
 
                                                                              47

deem fair and appropriate and which may provide for the selection for redemption
of portions of the principal amount of Securities of such series of a
denomination equal to or larger than the minimum authorized denomination for
Securities of such series. Unless otherwise provided by the terms of the
Securities of any series so selected for partial redemption, the portions of the
principal of Securities of such series so selected for partial redemption shall
be, in the case of Registered Securities, equal to $1,000 or an integral
multiple thereof or, in the case of Bearer Securities, equal to $5,000 or an
integral multiple thereof, and the principal amount of any such Security which
remains outstanding shall not be less than the minimum authorized denomination
for Securities of such series.

          The Security Registrar shall promptly notify the Company, the Trustee
and the Co-Security Registrar, if any, in writing of the Securities selected for
redemption and, in the case of any Security 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 Security redeemed or to be redeemed only in part, to the
portion of the principal of such Security which has been or is to be redeemed.

          SECTION 4.04.  Notice of Redemption.  Notice of redemption shall be
                         ---------------------
given in the manner provided in Section 1.06, not less than 30 nor more than 60
days prior to the Redemption Date, to each Holder of Securities to be redeemed.

          All notices of redemption shall state:

          (i)  the Redemption Date;

         (ii)  the Redemption Price;

        (iii)  if less than all Outstanding Securities of any series having the
     same terms are to be redeemed, the identification (and, in the case of
     partial redemption, the respective principal amounts) of the particular
     Securities to be redeemed;

         (iv)  that on the Redemption Date the Redemption Price will become due
     and payable upon each such 
<PAGE>
 
                                                                              48

     Security to be redeemed, and that interest, if any, thereon shall cease to
     accrue on and after said date;

          (v)  the place or places where such Securities, together in the case
     of Bearer Securities with all remaining coupons appertaining thereto, if
     any, maturing after the Redemption Date, are to be surrendered for payment
     of the Redemption Price;

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

        (vii)  the CUSIP number or the Euroclear or the CEDEL reference number
     (or any other number used by a Depositary to identify such Securities), if
     any, of the Securities to be redeemed.

          A notice of redemption published as contemplated by Section 1.06 need
not identify particular Registered Securities to be redeemed.

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

          SECTION 4.05.  Deposit of Redemption Price.  At or prior to the
                         ----------------------------
opening of business on any Redemption Date, the Company shall deposit or cause
to be deposited 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 5.03) an amount of money sufficient to pay the Redemption Price of all
the Securities which are to be redeemed on that date; provided, however, that
                                                      --------  -------      
deposits with respect to Bearer Securities shall be made with a Paying Agent or
Paying Agents located outside the United States except as otherwise provided in
Section 5.02, unless otherwise specified as contemplated by Section 3.01.

          SECTION 4.06.  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) 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

                                                                              49

void. Upon surrender of any such Securities for redemption in accordance with
said notice, such Securities shall be paid by the Company at the Redemption
Price; provided, however, that installments of interest on Bearer Securities
       --------  -------
whose Stated Maturity is on or prior to the Redemption Date shall be payable
only at an office or agency located outside the United States and, unless
otherwise specified as contemplated by Section 3.01, only upon presentation and
surrender of coupons for such interest. 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 on the close of business on the relevant Regular
Record Dates according to their terms and the provisions of Section 3.07.

          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 and, unless otherwise specified as
contemplated by Section 3.01, only upon presentation and surrender of those
coupons.

          If any Security called for redemption shall not be paid upon surrender
thereof for redemption, the principal shall, until paid, bear interest from the
Redemption Date at the rate borne by such Security, or as otherwise provided in
such Security.

          SECTION 4.07.  Securities Redeemed in Part.  Any Security which is to
                         ----------------------------
be redeemed only in part shall be surrendered at the office or agency of the
Company in a Place of Payment therefor (with, if the Company or the Security
Registrar so requires, due endorsement by, or a written instrument of transfer
in form satisfactory to the Company and the Security Registrar duly executed by,
the
<PAGE>

Holder of such Security or his attorney duly authorized in writing), and the
Company shall execute, and the Trustee shall authenticate and deliver to the
Holder of such Security without service charge, a new Security or Securities of
the same series and Stated Maturity, containing identical terms and conditions,
of any authorized denominations 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.

          SECTION 4.08.  Redemption Suspended During Event of Default.  The
                         ---------------------------------------------
Trustee shall not redeem any Securities (unless all Securities then Outstanding
are to be redeemed) or commence the giving of any notice of redemption of
Securities during the continuance of any Event of Default known to the Trustee,
except that where the giving of notice of redemption of any Securities shall
theretofore have been made, the Trustee shall, subject to the provisions of
Section 14.04, redeem such Securities, provided funds are deposited with it for
such purpose. Subject to the rights of the holders of Senior Indebtedness and
creditors in respect of General Obligations, except as aforesaid, any moneys
theretofore or thereafter received by the Trustee shall, during the continuance
of such Event of Default, be held in trust for the benefit of the Holders and
applied in the manner set forth in Section 7.06; provided, however, that in case
                                                 --------  -------
such Event of Default shall have been waived as provided herein or otherwise
cured, such moneys shall thereafter be held and applied in accordance with the
provisions of this Article.

Company covenants and agrees for the benefit of each series of Securities that
it will duly and punctually pay the principal of, premium, if any, and interest
on the Securities of such series in accordance with the terms of the Securities
of such series, any coupons appertaining thereto and this Indenture. Unless
otherwise specified as contemplated by Section 3.01 with respect to any series
of Securities, any interest due on Bearer Securities on or before Maturity shall
be payable only outside the United States upon presentation and surrender of

the several coupons for such interest installments as are evidenced thereby as
they severally mature.

          SECTION 5.02.  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 any series of Securities an office or agency where
Securities of that series may be presented or surrendered for payment, where
Securities of that series may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Company in respect of the
Securities of that series and this Indenture may be served. The Company will
give prompt written notice to the Trustee of the location, and of any change in
the location, of such office or agency. If Securities of a series may be
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 and
where notices and demands to or upon the Company in respect of the Securities of
that series and this Indenture may be served, (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 5.04); provided, however, that if the Securities of
                                  --------  -------                           
that series are listed on The International Stock Exchange of the United Kingdom
and the Republic of Ireland Limited or 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 or 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 such series 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

                                                                              52

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 Principal 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 5.04) at the place
specified for the purpose as contemplated by Section 3.01, and the Company
hereby appoints the Trustee as its agent to receive such respective
presentations, surrenders, notices and demands.

          Except as otherwise provided in the form of Bearer Security of any
particular series pursuant to the provisions of this Indenture, no payment of
principal, premium or interest on Bearer Securities shall be made at any office
or agency of the Company in the United States or by check mailed to any address
in the United States or by transfer to an account maintained with a bank located
in the United States; provided, however, payment of principal of and any premium
                      --------  -------                                         
and interest denominated in Dollars (including additional amounts payable in
respect thereof) on any Bearer Security may be made at an office or agency of,
and designated by, the Company located in the United States if (but only if)
payment of the full amount of such principal, premium, interest or additional
amounts in Dollars at all offices 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 similar restrictions and the
Trustee receives an Opinion of Counsel that such payment within the United
States is legal. Unless otherwise provided as contemplated by Section 3.01 with
respect to any series of Securities, at the option of the Holder of any Bearer
Security or related coupon, payment may be made by check in the currency
designated for such payment pursuant to the terms of such Bearer Security
presented or mailed to an address outside the United States or by transfer to an
account in such currency maintained by the payee with a bank located outside the
United States.

          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 of such purposes specified above in this Section
<PAGE>
 
                                                                              53

and may constitute and appoint one or more Paying Agents for the payment of such
Securities, in one or more other cities, and may from time to time rescind such
designations and appointments; provided, however, that no such designation,
                               --------  -------                           
appointment or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in each Place of Payment for
Securities of any series for such purposes. The Company will give prompt written
notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency. Unless and until the Company
rescinds one or more such appointments, the Company hereby appoints Citibank,
N.A., as its Paying Agent in the City of New York with respect to all series of
Securities having a Place of Payment in the City of New York.

          SECTION 5.03.  Money for Security Payments To Be Held in Trust.  If
                         ------------------------------------------------
the Company shall at any time act as its own Paying Agent for any series of
Securities, it will, on or before each due date of the principal of, premium, if
any, or interest on any of the Securities of such series and any appurtenant
coupons, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal, premium or interest so becoming
due until such sums shall be paid to such Persons or otherwise disposed of as
herein provided, and will promptly notify the Trustee of its action or failure
so to act.

          Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, at or prior to the opening of business on each
due date of the principal of, premium, if any, or interest on any Securities of
such series and any appurtenant coupons, deposit with a Paying Agent a sum
sufficient to pay the principal, premium or interest so becoming due, such sum
to be held in trust for the benefit of the Persons entitled to such principal,
premium or interest, and (unless such Paying Agent is the Trustee) the Company
will promptly notify the Trustee of its action or failure so to act.

          The Company will cause each Paying Agent other than the Trustee for
any series of Securities 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:

          (i)  hold all sums held by it for the payment of principal of,
     premium, if any, or interest on
<PAGE>
 
                                                                              54

     Securities of such series and any appurtenant coupons 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;

         (ii)  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, premium or interest on the Securities of such series
     or any appurtenant coupons; and

        (iii)  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 payments 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, premium, if any,
or interest on any Security of any series or any appurtenant coupons and
remaining unclaimed for two years after such principal, premium 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 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 5.04.  Additional Amounts.  If the Securities of a series
                         -------------------
provide for the payment of additional amounts, the Company will pay to the
Holder of any Security of any 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 premium, if any)
or interest on, or in respect of, any Security of any series or payment of any
related coupon or the net proceeds received on the sale or exchange of any
Security of any series, such mention shall be deemed to include mention of the
payment of additional amounts provided 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 (and
premium, if any) is made), and at least 10 days prior to each date of payment of
principal (and premium, if any) or 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 Principal 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 premium, if any) or interest on the Securities of
that series shall be made to Holders of Securities of that series or any related
coupons who are United States Aliens 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 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.

Company, an Officers' Certificate (provided, however, that one of the
                                   --------  -------
signatories of which shall be the Company's principal executive officer,
principal financial officer or principal accounting officer) stating, as to each
signer thereof, that:

     performance under this Indenture and under the terms of the Securities has
     been made under his supervision; and

         (ii)  to the best of his knowledge, based on such review, (a) the
     Company has fulfilled all its obligations and complied with all conditions
     and covenants under this Indenture and under the terms of the Securities
     throughout such year, or, if there has been a default in the fulfillment of
     any such obligation, condition or covenant specifying each such default
     known to him and the nature and status thereof, and (b) no event has
     occurred and is occurring which is, or after notice or lapse of time or
     both would become, a Default, or if such an event has occurred and is
     continuing, specifying such event known to him and the nature and status
     thereof.

          For purposes of this Section, compliance or default shall be
determined without regard to any period of grace or requirement of notice
provided for herein.

          SECTION 5.06.  Maintenance of Corporate Existence, Rights and 
                         ----------------------------------------------
Franchises.  So long as any of the Securities shall be Outstanding, 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 and franchises to carry on its
business; provided, however, that nothing in this Section 5.06 shall (i) require
          --------  -------
the Company 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

Holders, (ii) prevent any consolidation or merger of the Company, or any
conveyance or transfer of its property and assets substantially as an entirety
to any person, permitted by Article Ten, (iii) prevent the liquidation or
dissolution of the Company after any conveyance or transfer of its property and
assets substantially as an entirety to any person permitted by Article Ten.

Series of Securities.

          SECTION 6.02.  Preservation of Information; Communications to Holders.
                         -------------------------------------------------------

practicable, the names and addresses of Holders of Securities contained in the
most recent list furnished to the Trustee as provided in Section 6.01 and the

for a period of at least six months preceding the date of such application, and
such application states that the applicants desire to communicate with other
Holders of Securities of such series or with the Holders of all Securities with
respect to their rights under this Indenture or under such Securities and is
accompanied by a copy of the form of proxy or other communication which such
applicants propose to transmit, then the Trustee shall, within five Business
Days after the receipt of such application, at its election, either:

          (a) afford such applicants access to the information preserved at the
     time by the Trustee in accordance with Section 6.02(i); or

          (b) inform such applicants as to the approximate number of Holders of

such information, the Trustee shall, upon the written request of such
applicants, mail to each Holder of a Security of such series or all Holders of
Securities, as the case may be, whose names and addresses appear in the
information preserved at the time by the Trustee in accordance with Section
6.02(i), a copy of the form of proxy or other communication which is specified
in such request, with reasonable promptness after a tender to the Trustee of the
material to be mailed and of payment, or provision for the payment, of the
reasonable expenses of mailing, unless, within five days after such tender, the
Trustee shall mail to such applicants and file with the Commission, together
with a copy of the material to be mailed, a written statement to the effect
that, in the opinion of the Trustee, such mailing would be contrary to the best
interests of the Holders of Securities of such series or all Securities, as the
case may be, or would be in violation of applicable law. Such written statement
shall specify the basis of such opinion. If the Commission, after opportunity
for a hearing upon the objections specified in the written statement so filed,
shall enter an order refusing to sustain any of such objections or if, after the

shall find, after notice and opportunity for hearing, that all the objections so
sustained have been met and shall enter an order so declaring, the Trustee shall
mail copies of such material to all such Holders of Securities with reasonable
promptness after the entry of such order and the renewal of such tender;

applicants respecting their application.

to the names and addresses of the Holders of Securities in accordance with
Section 6.02(ii), regardless of the source from which such information was
derived, and that the Trustee shall not be held accountable by reason of mailing
any material pursuant to a request made under Section 6.02(ii).

(1) to all Holders of Registered Securities, as their names and addresses appear
in the Security Register and (2) to such Holders of Bearer Securities as have,
within the two years preceding such transmission, filed their names and
addresses with the Trustee for that purpose, and (3) except in the cases of
reports under Section 313(b)(2) of the Trust Indenture Act, to each Holder of a

any series of Securities, wherever used herein, means any one of the following
events (whatever the reason for such Event of Default and whether it shall be
voluntary or involuntary or be effected by operation of law or pursuant to any
judgment, decree or order of any court or any order, rule or regulation of any

          SECTION 7.02.  Acceleration of Maturity; Rescission and Annulment.  If
                         ---------------------------------------------------
an Event of Default with respect to any series of Securities for which there are
Securities 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 such series may declare the principal of all the
Securities of such series (or, if the Securities of that series are Original
Issue Discount Securities, such portion of the principal amount as may be
specified in the terms of that series) to be immediately due and payable, by a
notice in writing to the Company (and to the Trustee if given by Holders), and
upon any such declaration the same 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 such series, by written notice to the Company and the

               (c)  to the extent that payment of such interest is lawful,
          interest upon overdue installments of interest at the rate or rates
          prescribed therefor by the terms of the Securities of such series; and

         (ii)  all other Defaults with respect to Securities of that series,
     other than the nonpayment of the principal of Securities of that series
     which have become due solely by such declaration of acceleration, have been
     cured or waived as provided in Section 7.13.

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

          SECTION 7.03.  Collection of Indebtedness and Suits for Enforcement by
                         -------------------------------------------------------
Trustee.  The Company covenants that if:
- --------                                

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

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

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holder of any such Security or coupon appertaining thereto, if any, the whole
amount then due and payable on any such Security or coupon for principal,
premium, if any, and interest, with interest upon the overdue principal and
premium, if any, and (to the extent that payment of such interest shall be
lawful) upon overdue installments of interest, at the rate or rates prescribed
therefor by the terms of any such Security; and, in addition thereto, such
further amount as shall be sufficient to cover the reasonable costs and expenses
of collection, including the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel and any other amounts due
the Trustee under Section 8.07.

          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, 
<PAGE>
 
                                                                              64

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 a Default with respect to any series of Securities 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 7.04.  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 any 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, premium, if any, 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,
     premium, if any, and interest owing and unpaid in respect of the Securities
     and to file such other papers or documents as may be necessary or advisable
     in order to have the claims of the Trustee (including any claim for the
     reasonable compensation, expenses, disbursements and advances of the
     Trustee, its agents and counsel and any other amounts due the Trustee under
     Section 8.07) and of the Holders allowed in such judicial proceeding; and

         (ii)  to collect and receive any moneys or other property payable or
     deliverable on any such claims and to distribute the same,

                                                                              65

and any receiver, assignee, trustee, liquidator, sequestrator or other similar
official in any such judicial proceeding is hereby authorized by each Holder to
make such payments to the Trustee, and in the event that the Trustee shall
consent to the making of such payments directly to the Holders, to pay to the
Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 8.07.

          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 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.

Securities of any series, or coupons (if any) appertaining thereto, may be
prosecuted and enforced by the Trustee without the possession of any of the
Securities of such series or coupons appertaining thereto 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,

such series 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 of Securities of such series or to obtain or to seek

not be impaired without the consent of such Holder.

          SECTION 7.09.  Restoration of Rights and Remedies.  If the Trustee or

to such Holder, then and in every such case the Company, the Trustee and the
Holders shall, subject to any determination in such proceeding, be restored

Security or coupon to exercise any right or remedy accruing upon any Default
shall impair any such right or remedy or constitute a waiver of any such Default
or an acquiescence therein. Every right and remedy given by this Article or by
law to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

          SECTION 7.12.  Control by Holders.  The Holders of a majority in

     with this Indenture,

         (ii)  the Trustee shall not determine that the action so directed would
     be unjustly prejudicial to the Holders not taking part in such direction,

        (iii)  subject to the provisions of Section 8.01, the Trustee shall have
     the right to decline to follow any such direction if the Trustee in good
     faith shall, by a Responsible Officer or Officers of the Trustee, determine
     that the proceeding so directed would involve the Trustee in personal
     liability, and

principal amount of the Outstanding Securities of any series may on behalf of
the Holders of all the Securities of such series waive any past default
hereunder and its consequences, except a default not theretofore cured

     on any Security of such series, or

         (ii)  in respect of a covenant or provision hereof which under Article

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

          SECTION 7.14.  Undertaking for Costs.  All parties to this Indenture
                         ----------------------
agree, and each Holder of any Security by his acceptance thereof shall be deemed
to have agreed, that any court may in its discretion require, in any suit for
the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken, suffered or omitted by it as Trustee,
the filing by any party litigant in such suit of an undertaking to pay the costs
of such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant; but the provisions of this Section shall not apply to any
suit instituted by the Company, to any suit instituted by the Trustee, to any
suit instituted by any Holder, or group of Holders, holding in the aggregate
more than 10% in principal amount of the Outstanding Securities of any series,
or to any suit instituted by any Holder of Securities or coupons for the
enforcement of the payment of the principal of, premium, if any, or interest on
any Security or payment of any coupon on or after the respective Stated
Maturities expressed in such Security or coupon (or, in the case of redemption
or repayment, on or after the Redemption Date or Repayment Date).

          SECTION 7.15.  Waiver of Stay or Extension Laws.  The Company
                         ---------------------------------
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay or extension law wherever enacted, now or at
any time hereafter in force, which may affect the covenants or the performance
of this Indenture; and the Company (to the extent that it may lawfully do so)
hereby expressly waives all benefit or advantage of any such law, and covenants
that it will not hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted.

          (a)  the Trustee undertakes to perform such duties and only such
     duties as are specifically set forth in this Indenture with respect to
     Securities of such series, and no implied covenants or obligations shall be
     read into this Indenture against the Trustee with respect to such series;
     and

          (b)  in the absence of bad faith on its part, the Trustee may
     conclusively rely with respect to such series, 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 certificate 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 as to form to the
     requirements of the Indenture.

         (ii)  In case a Default with respect to any series of Securities has
occurred and is continuing, the Trustee shall exercise such of the rights and
powers vested in it by this Indenture with respect to 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 or her own
affairs.

        (iii)  No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own wilful misconduct, except that

          (a)  this Subsection shall not be construed to limit the effect of
     Subsection (i) of this Section;

         (b)  the Trustee shall not be liable for any error or judgment made in
     good faith by a Responsible Officer, unless it shall be proved that the

          (c)  the Trustee shall not be liable with respect to any action taken,
     suffered 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 Securities of such series; and

          (d)  no provision of this Indenture shall require the Trustee to
     expend or risk its own funds or otherwise incur any financial liability in
     the performance of any of its duties hereunder, or in the exercise of any
     of its rights or powers, if it shall have reasonable grounds for believing
     that repayment of such funds or adequate indemnity against such risk or
     liability is not reasonably assured to it.

          (iv)  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.

committee or a trust committee of directors and/or Responsible Officers of the
Trustee in good faith determines that the withholding of such notice is in the
interests of the Holders of Securities of such series; and provided further that

     of an express trust);

         (ii)  except as otherwise expressly provided herein, to reimburse the

this Indenture and the repayment of the Securities whether at the Stated
Maturity or otherwise.

          SECTION 8.08.  Disqualification; Conflicting Interests.  If the
                         ----------------------------------------
Trustee has or shall acquire a conflicting interest within the meaning of
Section 310 of the Trust Indenture Act, the Trustee shall either eliminate such
conflicting interest or resign, to the extent and in the manner provided by, and
subject to the provisions of, the Trust Indenture Act and this Indenture. To the
extent permitted by the Trust Indenture Act, the Trustee shall not be deemed to
have a conflicting interest with respect to the Securities of any series by
virtue of being Trustee with respect to the Securities of any particular series
of Securities other than that series.

          SECTION 8.09.  Corporate Trustee Required; Eligibility.  There shall
at all times be a Trustee with respect to each series of Securities hereunder
which shall be a corporation organized and doing business under the laws of the
United States of America, any State thereof or the District of Columbia,
authorized under such laws to exercise corporate trust powers, having a combined
capital and surplus of at least $5,000,000, subject to supervision or
examination by Federal or State authority; provided, however, that if Section
                                           --------  -------
310( a) of the Trust Indenture Act or the rules and regulations of the
Commission under the Trust Indenture Act at any time permit a corporation
organized and doing business under the laws of any other jurisdiction to serve
as trustee of an indenture qualified under the Trust Indenture Act, this Section
8.09 shall be automatically deemed amended to permit a corporation organized and
doing business under the laws of any such jurisdiction to serve as Trustee
hereunder. If such corporation publishes reports of condition at least annually,
pursuant to law or to the requirements of the aforesaid 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.
Neither the Company nor any person directly or indirectly controlling,
controlled by or under common control with the Company may serve as Trustee. If
at any time the Trustee with respect to any series of Securities shall cease to
be eligible in accordance with the

                                                                              77

provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.

          SECTION 8.10.  Resignation and Removal; Appointment of Successor.  (i)
                         --------------------------------------------------
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 8.11.

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

        (iii)  The Trustee may be removed with respect to any series of
Securities at any time 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.

         (iv)  If at any time:

          (a) the Trustee shall fail to comply with Section 8.08 with respect to
     any series of Securities after written request therefor by the Company or
     by any Holder who has been a bona fide Holder of a Security of such series
     for at least six months, or

          (b) the Trustee shall cease to be eligible under Section 8.09 with
     respect to any series of Securities and shall fail to resign after written
     request therefor by the Company or by any Holder of Securities of such
     series, or

          (c) the Trustee shall become incapable of acting with respect to any
     series of Securities 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,

                                                                              78

then, in any such case, (1) the Company by a Board Resolution may remove the
Trustee with respect to such series, or (2) subject to Section 7.14, any Holder
who has been a bona fide Holder of a Security of such series for at least six
months may, on behalf of himself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee with respect to such series.

          (v)  If the Trustee shall resign, be removed or become incapable of
acting with respect to any series of Securities, or if a vacancy shall occur in
the office of Trustee with respect to any series of Securities for any cause,
the Company, by a Board Resolution, shall promptly appoint a successor Trustee
or Trustees with respect to the Securities of that or those series (it being
understood that any such successor Trustee may be appointed with respect to the
Securities of one or more or all of such series and that at any time there shall
be only one Trustee with respect to the Securities of any particular series) and
shall comply with the applicable requirements of Section 8.11. If, within one
year after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to such series of Securities shall be
appointed by the 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 with respect to such series, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment, become the successor Trustee
with respect to such series and to that extent supersede the successor Trustee
appointed by the Company with respect to such series. If no successor Trustee
with respect to such series shall have been so appointed by the Company or the
Holders of Securities of such series 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 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 such series.

         (vi)  The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
by mailing written notice of such event by first-

                                                                              79

class mail, postage prepaid, to the Holders of Registered Securities of such
series as their names and addresses appear in the Security Register and, if
Securities of such series are issuable as Bearer Securities, by publishing
notice of such event once in an Authorized Newspaper in each Place of Payment
located outside the United States. Each notice shall include the name of the
successor Trustee with respect to the Securities of such series and the address
of its Principal Corporate Trust Office.

          SECTION 8.11.  Acceptance of Appointment by Successor.  (i) In the
                         ---------------------------------------
case of the appointment hereunder of a successor Trustee with respect to any
series of Securities, every such successor Trustee so appointed shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, and thereupon the resignation or removal of the
retiring Trustee shall become effective with respect to all or any series as to
which it is resigning as Trustee, 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 with respect to all or any
such series; but, on request of the Company or such 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 such retiring Trustee with respect to all or any such series; and
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder with respect to all or any
such series.

         (ii)  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 (a) 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, (b)
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 (c) shall add to or change any of the provisions of this Indenture
as shall be necessary to provide for or facilitate the administration of the
trusts hereunder by more than one Trustee, it being understood that nothing
herein or in such supplemental indenture shall constitute such Trustees co-
trustees of the same trust and that each such Trustee shall be Trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee; and upon the execution and delivery of
such supplemental indenture the resignation or removal of the retiring Trustee
shall become effective to the extent provided therein and each such successor
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee with respect
to the Securities of that or those series to which the appointment of such
successor Trustee relates; but, on request of the Company or any successor
Trustee, such retiring Trustee shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee hereunder
with respect to the Securities of that or those series to which the appointment
of such successor Trustee relates, subject nevertheless to its lien, if any,
provided for in Section 8.07.

        (iii)  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 (i) or (ii) of this Section, as the case may be.

         (iv)  No successor Trustee with respect to a series of Securities shall
accept its appointment unless at the time of such acceptance such successor
Trustee shall be qualified and eligible with respect to such series under this
Article.

          SECTION 8.12.  Merger, Conversion, Consolidation or Succession to
                         -------------------------------------------------- 
Business of Trustee. Any corporation into which the Trustee may be merged or

converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all of the
corporate trust business of the

Trustee, shall be the successor of the Trustee hereunder, provided that 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 8.13.  Preferential Collection of Claims against Company.  If
                         --------------------------------------------------
and when the Trustee shall be or become a creditor of the Company (or any other
obligor upon the Securities), the Trustee shall be subject to the provisions of
Section 311 of the Trust Indenture Act regarding the collection of such claims
against the Company (or any such other obligor). A Trustee that has resigned or
been removed shall be subject to and comply with said Section 311 to the extent
required thereby.

          SECTION 8.14.  Appointment of Authenticating Agents.  The Trustee may
                         -------------------------------------                 
appoint an Authenticating Agent or Agents, which may include any Affiliate of
the Company, with respect to one or more series of Securities.  Such
Authenticating Agent or Agents at the option of the Trustee shall be authorized
to act on behalf of the Trustee to authenticate Securities of such series issued
upon original issuance, exchange, registration of transfer or partial redemption
thereof or pursuant to Section 3.06, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder.  Whenever reference
is made in this Indenture to the authentication and delivery of Securities by
the Trustee or the Trustee's certificate of authentication or the delivery of
Securities to the Trustee for authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent, a certificate of authentication executed on behalf of the
Trustee by an Authenticating Agent and delivery of Securities to the
Authenticating Agent on behalf of the Trustee.  Each Authenticating Agent shall
be acceptable to the Company and shall at all times be a corporation organized
and doing business under the laws of the United States of America, any State
thereof or the District of Columbia, authorized under such laws to act as
Authen-

ticating Agent, having a combined capital and surplus of not less than
$5,000,000 and subject to supervision or examination by Federal or State
authority. Notwithstanding the foregoing, an Authenticating Agent located
outside the United States may be appointed by the Trustee if previously approved
in writing by the Company and if such Authenticating Agent meets the minimum
capitalization requirements of this Section 8.14. If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes
of this Section, the combined capital and surplus of such Authenticating Agent
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. If at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section,
such Authenticating Agent shall resign immediately in the manner and with the
effect specified in this Section.

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

          An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company. The Trustee may at any time
(and upon request by the Company shall) terminate the agency of an
Authenticating Agent by giving written notice thereof to such Authenticating
Agent and to the Company. Upon receiving such a notice of resignation or upon
such termination, or in case at any time such Authenticating Agent shall cease
to be eligible in accordance with the provisions of this Section, the Trustee
may appoint a successor Authenticating Agent which shall be acceptable to the
Company. Any successor Authenticating Agent upon acceptance of its appointment
hereunder shall become vested with all the rights, powers and duties of its
predecessor hereunder, with like effect as if originally named as an
Authenticating Agent. No

successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

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

referred to in the within-mentioned Indenture.

     proper claim in the form required by any proceeding referred to in this
     subparagraph (ii) prior to 30 days before the expiration of the time to

the Securities would be entitled except for the provisions hereof of cash,
property or securities otherwise distributable to the Senior Indebtedness shall,

holders of Senior Indebtedness (and, in the case of Section 14.09, the Holders
of the Securities, on the one hand, and creditors in respect of General
Obligations) on the other hand. Nothing contained in this Article Fourteen or
elsewhere in this Indenture or in the Securities is intended to or shall impair,

Indebtedness, and the Holders of the Securities, the obligation of the Company,
which is unconditional and absolute (and which, subject to the rights under this
Article Fourteen of the holders of the Senior Indebtedness and the rights under
Section 14.09 of creditors in respect of General Obligations, is intended to
rank equally with all other general obligations of the Company), to pay to the
Holders of the Securities the principal of, premium, if any, and interest on the
Securities as and when the same shall become due and payable in accordance with
their terms or to affect the relative rights of the Holders of the Securities

all remedies otherwise permitted by applicable law upon Default under this

Section 8.01, and the Holders of the Securities shall be entitled to rely upon
any order or decree of a court of competent jurisdiction in which such
dissolution, winding up, liquidation or reorganization proceedings are pending
or upon a certificate of the liquidating trustee or agent or other person making
any distribution to the Trustee or to the Holders of the Securities for the
purpose of ascertaining the persons entitled to participate in such
distribution, the holders of the Senior Indebtedness and other indebtedness of
the Company and the creditors in respect of General Obligations, the amount
thereof or payable thereon, the amount or amounts paid or distributed thereon
and all other facts pertinent thereto or to this Article Fourteen. In the
absence of any such liquidating trustee, agent or other person, the Trustee
shall be entitled to rely upon a written notice by a Person representing himself
to be a holder of Senior Indebtedness (or a trustee or representative on behalf
of such holder) or a creditor in respect of General Obligations as evidence that
such Person is a holder of Senior Indebtedness (or is such a trustee or
representative) or a creditor in respect of General Obligations, as the case may
be. In the event that the Trustee determines, in good faith, that further
evidence is required with respect to the right of any Person, as a holder of
Senior Indebtedness or a creditor in respect of General Obligations, to
participate in any payment or distribution pursuant to this Section or Section

satisfaction of the Trustee as to the amount of Senior Indebtedness or General
Obligations held by such Person, as to the extent to which such Person is
entitled to participation in such payment or distribution, and as to other facts
pertinent to the rights of such Person under this Section or Section 14.09, and
if such evidence is not furnished, the Trustee may defer any payment to such
Person pending judicial determination as to the right of such Person to receive
such payment.

          The obligations of the Company in respect of the Securities shall rank
on a parity with the Existing Subordinated Indebtedness and any other
obligations of the Company ranking on a parity with the Securities.

          With respect to the holders of Senior Indebtedness or creditors in
respect of General Obligations, the Trustee undertakes to perform or to observe
only such of its covenants and obligations as are specifically set forth in this
Article, and no implied covenants or obligations with

Obligations shall be read into this Indenture against the Trustee. The Trustee,
however, shall not be deemed to owe any fiduciary duty to the holders of Senior
Indebtedness or creditors in respect of General Obligations, and shall not be
liable to any such holders or creditors if it shall mistakenly pay over or
distribute to or on behalf of Holders of Securities or the Company moneys or
assets to which any holders of Senior Indebtedness or creditors in respect of
General Obligations shall be entitled by virtue of this Article Fourteen.

securities of the Company received upon the exercise of such remedy, or (iv)
prevent the application by the Trustee or any Paying Agent of any moneys
deposited with it hereunder to the payment of or on account of the principal of
or premium, if any, or interest on the Securities or prevent the receipt by the
Trustee or any Paying Agent of such moneys, if, prior to the second Business Day

                          ------------------
this Article or any other provisions of this Indenture, neither the Trustee nor
any Paying Agent shall be charged with knowledge of the existence of any Senior
Indebtedness or General Obligations or of any event which would prohibit the
making of any payment of moneys to or by the Trustee or such Paying Agent,
unless and until the Trustee or such Paying Agent shall have received written
notice thereof from the Company or from the holder of any Senior Indebtedness or
from the representative of any such holder or from any creditor in respect of
General Obligations.

the Trustee of any of its rights as such holder or creditor.

Subordinated Indebtedness; Payment of Proceeds in Certain Cases. (i) Subject to

the provisions of this Section and to any provisions established or determined
with respect to Securities of any series pursuant to Section 3.01, the
Securities shall rank pari passu in right of payment with the Existing
Subordinated Indebtedness.

         (ii)  Upon the occurrence of any of the events specified in the first
     paragraph of Section 14.02, the provisions of that Section and the
     corresponding provisions of each indenture or other instrument or document
     establishing or governing the terms of any Existing Subordinated
     Indebtedness shall be given effect on a pro rata basis to determine the
     amount of cash, property or securities which may be payable or deliverable
     as between the holders of Senior Indebtedness, on the one hand, and the
     Holders of the Securities and holders of Existing Subordinated
     Indebtedness, on the other hand.

        (iii)  If, after giving effect to the provisions of Section 14.02, and
     the respective corresponding provisions of each indenture or other
     instrument or document establishing or governing the terms of any Existing
     Subordinated Indebtedness on such pro rata basis, any amount of cash,

     respect of the Securities ("Excess Proceeds"), and any creditors in respect
     of General Obligations shall not have received payment in full of all
     amounts due or to become due on or in respect of such General Obligations
     (and provision shall not have been made for such payment in money or
     money's worth), then such Excess Proceeds shall first be applied (ratably
     with any amount of cash, property or securities available for payment or
     distribution in respect of any other indebtedness of the Company that by
     its express terms provides for the payment over of amounts corresponding to
     Excess Proceeds to creditors in respect of General Obligations) to pay or

     giving effect to any concurrent payment or distribution to or for creditors
     in respect of General Obligations. Any Excess Proceeds remaining after
     payment (or provision for payment) in full of all General Obligations shall
     be available for payment or distribution in respect of the Securities.

         (iv)  In the event that, notwithstanding the foregoing provisions of
     subsection (iii) of this Section, the Trustee or Holder of any Security
     shall, in the circumstances contemplated by such subsection, have received
     any payment or distribution of assets of the Company of any kind or
     character, whether in cash, property or securities, before all General
     Obligations are paid in full or payment thereof duly provided for, and if
     such fact shall, at or prior to the time of such payment or distribution
     have been made known to the Trustee or, as the case may be, such Holder,
     then and in such event, subject to any obligation that the Trustee or such
     Holder may have pursuant to Section 14.02, such payment or distribution
     shall be paid over or delivered forthwith to the trustee in bankruptcy,
     receiver, liquidating trustee, custodian, assignee, agent or other Person
     making payment or distribution of assets of the Company for payment in
     accordance with subsection (iii).

          (v)  Subject to the payment in full of all General Obligations, the
     Holder of the Securities shall be subrogated (equally and ratably with the
     holders of all indebtedness of the Company that by its express terms
     provides for the payment over of amounts corresponding to Excess Proceeds
     to creditors in respect of General Obligations and is entitled to like
     rights of subrogation) to the rights of the creditors in respect of General
     Obligations to receive payments or distributions of cash, property or
     securities applicable to the General Obligations until the principal of and
     interest on the Securities shall be paid in full. For purposes of such
     subrogation, no payments or distributions to creditors in respect of
     General Obligations of any cash, property or securities to which Holders of
     the Securities or the Trustee would be entitled except for the provisions
     of this Section, and no payments over pursuant to the provisions of this
     Section to creditors in respect of General Obligations by Holders of
     Securities or the Trustee, shall, as among the Company, its creditors

     respect of General Obligations, on the other hand, after giving effect to
     the rights of the holders of Senior Indebtedness, as provided in this
     Article. Nothing contained in subsections (iii), (iv) and (v) of this
     Section is intended to or shall affect the relative rights against the
     Company of the Holders of the Securities and (a) the holders of Senior
     Indebtedness (b) the holders of Existing Subordinated Indebtedness or (c)
     other creditors of the Company other than creditors in respect of General
     Obligations.

Maturity shall be repaid in accordance with their terms and (except as otherwise
specified pursuant to Section 3.01 for Securities of such series) in accordance
with this Article.

          SECTION 15.02.  Repayment of Securities.  Each Security which is
                          ------------------------
subject to repayment in whole or in part at the option of the Holder thereof on

be furnished to them such security or indemnity as they may require to save each
of them and any Paying Agent harmless. If thereafter the Holder of such Bearer
Security shall surrender to the Trustee or any Paying Agent any such missing
coupon in respect of which a deduction shall have been made from the Repayment
Price, such Holder shall be entitled to receive the amount so deducted without
interest thereon; provided, however, that interest represented by coupons

however, that the issuance of a Registered Security therefor shall be subject to

consequences under the United States federal income tax laws then in effect and
the Company has delivered to the Trustee a Company Order directing the Trustee
not to make such issuances thereafter unless and until the Trustee receives a

Indenture, the Trustee may make such reasonable regulations as it may deem
advisable for any meeting of Holders of Securities of such series in regard to
proof of the holding of Securities of such series and of the appointment of
proxies and in regard to the appointment and duties of inspectors of votes, the
submission and examination of proxies, certificates and other evidence of the
right to vote, and such other matters concerning the conduct of the meeting as
it shall deem appropriate. Except as otherwise permitted or required by any such
regulations, the holding of Securities shall be proved in the manner specified
in Section 1.04 and the appointment of any proxy

                                                                             108

shall be proved in the manner specified in Section 1.04 or, in the case of
Bearer Securities, by having the signature of the person executing the proxy
witnessed or guaranteed by any trust company, bank or banker authorized by
Section 1.04 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 1.04 or
other proof.

          (b)  The Trustee shall, by an instrument in writing, appoint a
temporary chairperson of the meeting, unless the meeting shall have been called
by the Company or by Holders of Securities as provided in Section 16.02(ii), 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
chairperson. A permanent chairperson 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 (or the
equivalent in ECU, any other composite currency or a Foreign Currency) of
Securities of such series held or represented by him; provided, however, that no
                                                      --------  -------
vote shall be cast or counted at any meeting in respect of any Security
challenged as not Outstanding and ruled by the chairperson of the meeting not to
be Outstanding. The chairperson 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 16.02 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 16.06.  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 the
signatures of the Holders of Securities of such series or of their
representatives by proxy and the principal amounts and

                                                                             109

serial numbers of the Outstanding Securities of such series held or represented
by them. The permanent chairperson of the meeting shall appoint two inspectors
of votes who shall count all votes cast at the meeting for or against any
resolution and who shall make and file with the secretary of the meeting their
verified written reports in triplicate of all votes cast at the meeting. A
record, at least in triplicate, of the proceedings of each meeting of Holders of
Securities of any series shall be prepared by the secretary of the meeting and
there shall be attached to said record the original reports of the inspectors of
votes on any vote by ballot taken thereat and affidavits by one or more persons
having knowledge of the facts setting forth a copy of the notice of the meeting
and showing that said notice was given as provided in Section 16.02 and, if
applicable, Section 16.04. Each copy shall be signed and verified by the
affidavits of the permanent chairperson 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.

[LOGO OF BANC ONE CORPORATION
        APPEARS HERE]


July 7, 1995



To: The Directors of BANC ONE CORPORATION


This opinion is being provided by the undersigned, as General Counsel of BANC 
ONE CORPORATION ("BANC ONE"). In such capacity I, or attorneys under my 
supervision, have represented BANC ONE in connection with the filing with the 
Securities and Exchange Commission (the "Commission") pursuant to the Securities
Act of 1933, as amended (the "Securities Act"), of a Registration Statement on 
Form S-3, File No. 33-60807, which also constitutes Post-Effective Amendment 
No. 1 to the Registration Statement on Form S-3, File No. 33-35971 (together,
the "Registration Statement"), for the purpose of registering under the
Securities Act one or more series of its unsecured debt securities ("Debt
Securities"), which may be either senior or subordinated in priority of payment.

In rendering the opinions set forth below, I or attorneys under my supervision 
have examined originals, or copies certified or otherwise identified to my 
satisfaction, of such documents, corporate records and other instruments as I 
have deemed necessary or appropriate for the purposes of this opinion, including
without limitation (i) the form of senior indenture filed as Exhibit 4.1 to the 
Registration Statement (the "Senior Indenture") and (ii) the form of 
subordinated indenture filed as Exhibit 4.2 to the Registration Statement (the 
"Subordinated Indenture" and, together with the Senior Indenture, the 
"Indentures").

Based upon and subject to the foregoing and after examination of such matters of
law as I have deemed applicable or relevant to this opinion, I am of the opinion
that, when (i) the Registration Statement has been filed and has become 
effective under the Securities Act, (ii) the Indentures have been duly 
authorized and validly executed by each party thereto, (iii) the terms of the 
Debt Securities and of their issue and sale have been duly authorized by the 
board of directors of BANC ONE (the "Board") and established in conformity with 
the resolutions of the Board and the applicable Indenture so as not to violate 
any applicable law or result in a default under or breach of any agreement or 
instrument binding upon BANC ONE and so as to comply with any requirement or 
restriction imposed by any court or governmental body having jurisdiction over 
BANC ONE and (iv) the Debt Securities have been duly executed and authenticated 
in accordance with the applicable Indenture and issued and sold in the manner 
contemplated by the Registration Statement, the Debt Securities will constitute 
valid and binding obligations of BANC ONE, enforceable against BANC ONE in 
accordance with their terms, subject as to enforceability, to the effects of 
applicable bankruptcy, insolvency, moratorium, fraudulent transfer or 
conveyance, reorganization, receivership, conservatorship and other similar laws

or hereafter in effect relating to the rights of creditors generally, and 
subject to general principles of equity (whether applied in a proceeding at law 
or in equity).

The opinions expressed herein are limited to the laws of the State of Ohio and 
the federal laws of the United States of America. I hereby consent to (i) the 
use and filing of this opinion as an exhibit to the Registration Statement and 
to the reference to this opinion under the heading "Legal Opinions" in any 
prospectus filed in connection with the Registration Statement and (ii) the 
incorporation by reference of this opinion into a subsequent registration 
statement filed by BANC ONE pursuant to Rule 462(b) under the Securities Act 
relating to the offering covered by the Registration Statement. In giving such 
consent, I do not thereby admit that I come within the category of persons whose
consent is required under Section 7 of the Securities Act of 1933 or the General
Rules and Regulations thereunder.

Very truly yours,
