dollars, foreign currencies or foreign currency units, and the principal of,
and any interest on, the Debt Securities may be payable in U.S. dollars,
foreign currencies or foreign currency units.
  The Senior Securities will rank equally with all other unsubordinated and
unsecured indebtedness of the Company. The Subordinated Securities will be
unsecured and subordinated as described under "Subordinated Securities".
  Unless otherwise specified in the Prospectus Supplement relating to
Subordinated Securities, payment of the principal of Subordinated Securities
may be accelerated only in the case of certain events involving the bankruptcy
or insolvency of the Company, and no right of acceleration will exist in the
case of default in the payment of principal or interest or in the performance

Warrants; (vi) with regard to Preferred Stock, the specific number of shares,
title, stated value and liquidation preference of each share, issuance price,
dividend rate or method of calculation, dividend periods, dividend payment

a share of Preferred Stock which each such Depositary Share will represent.
  The Prospectus Supplement will also contain information, where applicable,
about certain U.S. federal income tax considerations relating to, and any

Supplement.
  The Securities may be sold by the Company 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. If any agent of
the Company, or any underwriter, is involved in the sale of the Securities, the
name of such agent or underwriter, the principal or stated amount to be
purchased by it, any applicable commissions or discounts and the net proceeds
to the Company from such sale will be set forth in, or may be calculated from,
the Prospectus Supplement. The Company may also issue contracts under which the
counterparty may be required to purchase Debt Securities, Preferred Stock,
Depositary Shares or Common Stock. Such contracts would be issued with the Debt
Securities, Preferred Stock, Depositary Shares and/or Warrants in amounts, at
prices and on terms to be set forth in the applicable Prospectus Supplement.
The aggregate net proceeds to the Company from the sale of all the Securities
will be the public offering or purchase price of the Securities sold less the
aggregate of such commissions and discounts and other expenses of issuance and
distribution. An affiliate of the Company may from time to time act as an agent
or underwriter in connection with the sale of Securities to the extent
permitted by applicable law. See "Plan of Distribution".

                           FIRST CHICAGO CORPORATION
 
GENERAL
 
  The Company is a multi-bank holding company incorporated in Delaware. At
December 31, 1994, the Company had consolidated assets of $65.9 billion and
total equity capital of $4.5 billion. The principal asset of the Company is the
capital stock of The First National Bank of Chicago ("FNBC"), which provides a
broad range of banking, fiduciary, financial and other services domestically
and overseas. At December 31, 1994, FNBC had deposits of $25.7 billion and
assets of approximately $42.5 billion.
 
  The Company also owns all the outstanding capital stock of American National
Corporation ("ANC") and FCC National Bank ("FCCNB"). ANC is the holding company
for American National Bank and Trust Company of Chicago ("ANB"). FCCNB is a
Delaware-based bank primarily engaged in the issuance of VISA and MasterCard
credit cards. Together with these banking organizations, the Company, directly
or indirectly, owns the stock of various nonbank companies engaged in
businesses related to banking and finance, including venture capital, leasing
and investment management subsidiaries.
 
  In addition to its equity investment in subsidiaries, the Company, directly
or indirectly, raises funds principally to finance the operations of its
nonbank subsidiaries. A substantial portion of the Company's annual income
typically has been derived from dividends from its subsidiaries, and from
interest on loans, some of which are subordinated, to its subsidiaries.
 
  Because the Company is a holding company, its rights and the rights of its
creditors, including the holders of the Debt Securities, to participate in the
assets of any subsidiary upon the subsidiary's liquidation or recapitalization
would be subject to the prior claims of such subsidiary's creditors except to
the extent that the Company may itself be a creditor with recognized claims
against the subsidiary.
 
  The Company's executive offices are located at One First National Plaza,
Chicago, Illinois 60670, and the telephone number is (312) 732-4000.
 
SUPERVISION AND REGULATION
 
  The Company is a legal entity separate and distinct from the Company's
banking subsidiaries (the "Banks") and the Company's other affiliates.
Investors should be aware of the various legal limitations on the extent to
which the Banks can finance or otherwise supply funds to the Company or various
of its affiliates. In particular, the Banks are subject to certain restrictions
imposed by the laws of the United States on any extensions of credit to the
Company or, with certain exceptions, other affiliates, on investments in stock
or other securities thereof, on the taking of such securities as collateral for
loans, and on the terms of transactions between the Banks and other
subsidiaries. The Company and its subsidiaries, including the Banks, are also
subject to certain restrictions with respect to engaging in the issuance,
flotation, underwriting, public sale or distribution of securities. The Banks
are subject to regulation by the Office of the Comptroller of the Currency
 
                                       3
<PAGE>
 
(the "Comptroller"), the Board of Governors of the Federal Reserve System (the
"Federal Reserve Board") and the Federal Deposit Insurance Corporation
("FDIC"). These national banks are examined by the Comptroller, and FNBC's and
ANB's operations in other countries are subject to various restrictions imposed
by the laws of such countries.
 
  Federal law prohibits the Company and certain of its affiliates from
borrowing from the Banks without the prior approval of the respective Bank's
Board of Directors and unless such loans are secured by U.S. Treasury or other
specified obligations. Further, such secured loans and investments by any of
the Banks are limited in amount as to the Company or any other such affiliate
to 10% of the respective Bank's capital and surplus and as to the Company and
all such affiliates to an aggregate 20% of the respective Bank's capital and
surplus. Under Federal Reserve Board policy, the Company is expected to act as
a source of financial strength to each Bank and to commit resources to support
such Bank in circumstances where it might not do so absent such policy. In
addition, any capital loans by the Company to any of the Banks would be
subordinate in right of payment to deposits and to certain other indebtedness
of such Bank.
 
  Additionally, there are certain regulatory limitations on the payment of
dividends to the Company by the Banks. Dividend payments by national banks are
limited to the lesser of (i) the level of "undivided profits then on hand" less
the amount of bad debts, as defined, in excess of the allowance for credit
losses and (ii) absent regulatory approval, an amount not in excess of "net
profits" for the current year combined with "retained net profits" for the
preceding two years. As of December 31, 1994, the Banks could have declared
additional dividends of approximately $664 million without approval of the
Comptroller. The payment of dividends by any Bank may also be affected by other
factors, such as the maintenance of adequate capital for such Bank. The
Comptroller also has authority under the Financial Institutions Supervisory Act
to prohibit a national bank from paying dividends if, in the Comptroller's
opinion, the payment of dividends would, in light of the financial condition of
such bank, constitute an unsafe or unsound practice.
 
  As a bank holding company, the Company and its subsidiaries are prohibited
from engaging in certain tie-in arrangements in connection with extensions of
credit or providing property or services.
 
CAPITAL ADEQUACY
 
  The Federal Reserve Board has adopted risk-based capital guidelines for bank
holding companies that require bank holding companies to maintain a minimum
ratio of total capital to risk-weighted assets (including certain off-balance-
sheet items, such as standby letters of credit) of 8%. At least half of total
capital must be composed of common stockholders' equity, noncumulative
perpetual preferred stock and a limited amount of cumulative perpetual
preferred stock, less disallowed intangibles and other adjustments (primarily
goodwill) ("Tier I capital"). The remainder ("Tier II capital") may consist of
subordinated debt, other preferred stock, certain other instruments and a
limited amount of loan loss reserves. At December 31, 1994, the Company's
consolidated Tier I capital and total capital ratios were 8.8% and 13.4%,
respectively.
 
  In addition, the Federal Reserve Board has established minimum leverage ratio
guidelines for bank holding companies. These guidelines provide for a minimum
ratio of Tier I capital to total average assets (the "leverage ratio") of 3%
for bank holding companies that meet certain specified criteria, including
those having the highest regulatory rating. All other bank holding companies
generally are required to maintain a leverage ratio of at least 3% plus an
additional cushion of 100 to 200 basis points. The Company's leverage ratio at
December 31, 1994, was 7.5%. The guidelines also provide that bank holding
companies experiencing internal growth or making acquisitions will be expected
to maintain strong capital positions substantially above the minimum
supervisory levels without significant reliance on intangible assets.
Furthermore, the Federal Reserve Board has indicated that it will consider a
"tangible Tier I capital leverage ratio" (deducting all intangibles) and other
indicia of capital strength in evaluating proposals for expansion or new
activities.

  Each of the Banks is subject to similar risk-based and leverage capital
requirements adopted by the Comptroller. Each of the Company's Banks was in
compliance with the applicable minimum capital requirements as of December 31,
1994. Neither the Company nor any of the Banks has been advised by any federal
banking agency of any specific minimum leverage ratio requirement applicable to
it.
 
  Failure to meet capital requirements could subject a bank to a variety of
enforcement remedies, including the termination of deposit insurance by the
FDIC, and to certain restrictions on its business, which are described below
under "Recent Legislation".
 
  Bank regulators continue to indicate their desire to raise capital
requirements applicable to banking organizations beyond their current levels.
However, the management of the Company is unable to predict whether higher
capital requirements would be imposed and, if so, at what levels and on what
schedule.
 
RECENT LEGISLATION
 
  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 the
Company, the Banks and other depository institutions located in the United
States.
 
  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 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,
 
                                       5
<PAGE>
 
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 fails 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 "FDIC Insurance," 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.
 
  The Financial Institutions Reform, Recovery and Enforcement Act of 1989
("FIRREA"), among other things, provides generally that, upon the default of
any bank of a multi-unit holding company, the FDIC may assess an affiliated
insured depository institution for the estimated losses incurred by the FDIC.
Specifically, FIRREA provides that 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, 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 a default. "Default" is defined generally as the appointment of a~
conservator or receiver. "In danger of a default" is defined generally as the
existence of certain conditions indicating that a default is likely to occur
in the absence of regulatory assistance. All of the Banks are FDIC-insured
depository institutions.
 
FDIC INSURANCE
 
  The Banks are subject to FDIC deposit insurance assessments. Under the
FDIC's risk-based assessment system effective January 1, 1994, the prior flat
assessment rate of 0.23% per annum on the amount of domestic deposits has been
changed to a rate based on classification of a depository institution in one
of nine risk assessment categories. Such classification is based upon the
institution's capital level and upon certain supervisory evaluations of the
institution by its primary regulator.
 
  The assessment rate schedule currently in effect creates a 0.08% spread in
assessment rates, ranging from 0.23% per annum to 0.31% per annum, between
banks classified as strongest and weakest by the FDIC. In February 1995, the
FDIC proposed reducing the minimum assessment rate applicable to the strongest
banks from 0.23% per annum to 0.04% per annum. Under this proposal, the
premium for the weakest banks would remain at 0.31% per annum.
 
INTERSTATE BANKING AND BRANCHING
 
  The Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 (the
"Riegle-Neal Act") significantly revises prior laws applicable to interstate
acquisitions of banks and bank holding companies and the branching powers of
national banks. Prior to the Riegle-Neal Act, the Federal Reserve Board was
not permitted to approve an application to acquire shares of a bank located
outside the state in which the operations of the applicant's bank subsidiaries
were principally conducted unless the acquisition were
 
                                       6
<PAGE>
 
specifically authorized by a statute of the acquired bank's state. Commencing
September 29, 1995, the Federal Reserve Board is authorized to approve an
application of an adequately capitalized and adequately managed bank holding
company to acquire control of a bank located in another state without regard to
whether such transaction is prohibited under the law of such state. The Federal
Reserve Board may not, however, approve such an application if, following the
acquisition, the applicant would control either (1) more than 10% of all
insured depository institution deposits in the United States or (2) under
certain circumstances, 30% or more of all insured depository institution
deposits in any state where either the applicant or the acquired bank is
located. The 30% limit on aggregate deposits that may be controlled by an
applicant can be adjusted by the states on a non-discriminatory basis.
 
  The Riegle-Neal Act also revises the rules applicable to mergers between
insured banks located in different states. Before passage of the Riegle-Neal
Act, such mergers generally were not authorized. Commencing June 1, 1997,
however, adequately capitalized and adequately managed insured banks in
different states may merge without regard to whether the merger is authorized
under the law of any state. States may elect to prohibit interstate bank
mergers or may elect to permit early interstate bank mergers by adopting, prior
to June 1, 1997, legislation that expressly so provides, and that applies on
equal terms to all out-of-state banks. The Riegle-Neal Act provides that an
interstate merger involving the acquisition of a branch (as distinguished from
an entire bank) or the de novo establishment of a national bank branch in
another state may be approved only if the law of the host state expressly
permits such action. An interstate merger may not be approved if, following the
merger, the resulting bank would control (1) more than 10% of all insured
depository institution deposits in the United States or (2) under certain
circumstances, 30% or more of all insured depository institution deposits in
any state where the resulting bank will be located. The 30% limit on aggregate
deposits that may be controlled by the resulting bank can be adjusted by the
states on a non-discriminatory basis. The laws of the host state regarding
community reinvestment, consumer protection, fair lending and the establishment
of intrastate branches will apply to any out-of-state branch of a national bank
unless preempted by federal law or the Comptroller determines that application
of such laws would have a discriminatory effect on the national bank.
 
  The Riegle-Neal Act contains a number of other provisions related to banks
and bank holding companies, including: authorization of interstate branching by
foreign banks; additional branch closing notice requirements for interstate
banks proposing to close a branch in a low or moderate income area; amendments
to the Community Reinvestment Act of 1977 to require separate written
evaluations of an insured depository institution for each state in which it
maintains branches; a prohibition on interstate banks maintaining out-of-state
deposit production offices; and authorization for a bank subsidiary of a bank
holding company to receive deposits, renew time deposits, close and service
loans and receive payments on loans as agent for a depository institution
affiliate of such bank.
 
  The extent to, and terms on, which full interstate branching and certain
other actions authorized under the Riegle-Neal Act are implemented will depend
on the actions of entities other than the Company and the Banks, including the
legislatures of the various states. Further developments by state and federal
authorities, including legislation, with respect to matters covered by the
Riegle-Neal Act reasonably can be anticipated to occur in the future. In
addition, there may be new, significant banking legislation introduced in the
current Congress related to bank holding companies and their powers; the
likelihood of passage and effect, if any, of such legislation on the Company
and the Banks cannot be predicted.
 
  The Illinois Bank Holding Company Act (the "Illinois Act") provides that any
out-of-state bank holding company whose principal place of business is in a
state that grants Illinois bank holding companies reciprocal authority may
acquire control of an Illinois bank or bank holding company. The approval of
the Illinois Commissioner of Banks and Trust Companies is required to complete
such an interstate acquisition in Illinois. The Illinois Act also permits
intrastate acquisitions throughout Illinois by Illinois bank holding companies.
All interstate and intrastate bank acquisitions by the Company are subject to
the approval of the Federal Reserve Board.

CONSOLIDATED RATIOS OF EARNINGS TO FIXED CHARGES
 
  The ratios of earnings to fixed charges for the Company, which are computed
on the basis of the total enterprise (as defined by the Commission) by dividing
earnings before fixed charges and income taxes by fixed charges, are set forth
below for the periods indicated. Also set forth below are the ratios of
earnings to combined fixed charges and preferred stock dividends, which are
computed on the basis of the total enterprise by dividing earnings before fixed
charges and income taxes by fixed charges and preferred stock dividend
requirements for the periods indicated. Fixed charges consist principally of
interest expense on all long- and short-term borrowings, excluding or including
interest on deposits as indicated.

                                USE OF PROCEEDS
 
  Unless otherwise provided in the Prospectus Supplement, the Company will use
the net proceeds from the sale of the Securities for general corporate
purposes, including the funding of investments in, or extensions of credit to,
the Company's subsidiaries. Pending the uses described above, the Company may
temporarily invest the net proceeds from the sale of the Securities in various
short-term securities or apply the net proceeds to reduce short-term
indebtedness. Based upon the historic and anticipated future growth of the
Company and the financial needs of its subsidiaries, the Company anticipates
that it will, on a recurrent basis, engage in additional financings in
character and amount to be determined.
 
                         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 dated as of
May 1, 1995 (the "Senior Indentures"), between the Company and Marine Midland
Bank, as Trustee ("Marine Midland"). The Subordinated Securities will be issued
under an Indenture dated as of May 1, 1995 (the "Subordinated Indenture"),
between the Company and The Chase Manhattan Bank (National Association), as
Trustee ("Chase"). The Senior Indenture and the Subordinated Indenture are
collectively referred to herein as the "Indentures". References to the
"Trustee" shall mean Marine Midland or Chase, 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
 
                                       8
<PAGE>
 
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.
 
  None 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 the Company and may be denominated in any
currency or currency unit designated by the Company. 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 the Company 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 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 the Company 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) the terms, if any, upon which
the Debt Securities may be convertible into or exchanged for Common Stock,
Preferred Stock (which may be represented by Depositary Shares), other Debt
Securities, Debt Warrants, Common Stock Warrants or Preferred Stock Warrants or
any other securities of the Company or any other obligor and the terms and
conditions upon which such conversion or exchange will be effected, including
the initial conversion or exchange price or rate, the conversion or exchange
period and any other provision in addition to or in lieu of those described
herein; (20) any additional covenants or Events of Default not currently set
forth in the
 
                                       9
<PAGE>
 
applicable Indenture; and (21) 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.
 
  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
Note Registrar specified according to the terms of the applicable Indenture.
The Company has agreed in each of the Indentures that, with respect to
Registered Securities having The City of New York as a place of payment, the
Company 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 the Company 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.
 
 
                                       10
<PAGE>
 
  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. The Company
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 the Company, 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.
 
  Subject to certain restrictions relating to Bearer Securities, the Company
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. The Company 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 the Company within 90 days, the Company 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, the Company
may at any time and in its sole
 
                                       11
<PAGE>
 
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 the Company 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 the
Company, 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 the Company, 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 the Company, 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 the Company may
designate from time to time, except that, at the option of the Company, 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 the Company 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 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 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.
 
CONSOLIDATION, MERGER OR SALE OF ASSETS
 
  Each Indenture provides that the Company 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 the
Company'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
 
                                       12
<PAGE>
 
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 the Company 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.
 
CONVERTIBLE DEBT SECURITIES
 
  Certain Debt Securities (the "Convertible Debt Securities") may be
convertible into other Securities of the Company. The holders of such
Convertible Debt Securities of a specified series may be entitled or, if so
provided in the applicable Prospectus Supplement, may be required at such time
or times specified in the applicable Prospectus Supplement, subject to prior
redemption, repayment or repurchase, to convert any Convertible Debt Securities
of such series (in denominations set forth in the applicable Prospectus
Supplement) into Common Stock, Preferred Stock, Common Stock Warrants,
Preferred Stock Warrants, another series of Debt Securities, Debt Warrants or
Depositary Shares, as the case may be, (collectively, the foregoing securities
into which the Convertible Debt Securities may convert are referred to herein
as "Conversion Securities") at the conversion price set forth in the applicable
Prospectus Supplement, subject to adjustment as described below, and in the
applicable Prospectus Supplement. The relevant provisions for each series of
Convertible Debt Securities will be set forth in the applicable Prospectus
Supplement. Except as described below or in the applicable Prospectus
Supplement, no adjustment will be made upon conversion of any Convertible Debt
Securities for interest accrued thereon or for dividends on any Conversion
Securities issued. If any Convertible Debt Securities not called for redemption
are converted between a Regular Record Date for the payment of interest and the
next succeeding Interest Payment Date, such Convertible Debt Securities must be
accompanied by funds equal to the interest payable on such succeeding Interest
Payment Date on the principal amount so converted. The Company is not required
to issue fractional shares of Common Stock or Preferred Stock upon conversion
of Convertible Debt Securities that are convertible into Common Stock or
Preferred Stock, respectively, and, in lieu thereof, will pay a cash
adjustment, in the case of Convertible Debt Securities convertible into Common
Stock, based upon the market value of the Common Stock, and in the case of
Convertible Debt Securities convertible into Preferred Stock, based upon the
liquidation preference of such series of Preferred Stock, unless otherwise
specified in the Prospectus Supplement. In the case of Convertible Debt
Securities convertible into securities other than Common Stock or Preferred
Stock, such adjustment will be based on such method as is set forth in the
Prospectus Supplement.
 
 
                                       13
<PAGE>
 
  The conversion price for a series of Convertible Debt Securities that are
convertible into Common Stock is subject to adjustment upon the occurrence of
certain events under formulas that will be set forth in the applicable
Prospectus Supplement.
 
  In the event of a taxable distribution to holders of Common Stock or
Preferred Stock (or other transaction) which results in any adjustment of the
conversion price of Convertible Debt Securities that are convertible into
Common Stock or Preferred Stock, the holders of such Convertible Debt
Securities may, in certain circumstances, be deemed to have received a
distribution subject to United States Federal income tax as a dividend; in
certain other circumstances, the absence of such an adjustment may result in a
taxable dividend to the holders of Common Stock or Preferred Stock acquired
upon conversion of such Convertible Debt Securities.
 
                               SENIOR SECURITIES
 
  The Senior Securities will be direct, unsecured obligations of the Company
and will rank pari passu with all outstanding unsecured senior indebtedness of
the Company.
 
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 the Company in the Senior Indenture
with respect to Senior Securities of such series and continuance of such
default for 60 days after written notice; (iv) due acceleration of any
indebtedness for borrowed money in principal amount in excess of $1,000,000 of
the Company under the terms of the instrument under which such indebtedness is
issued or secured, if such acceleration is not rescinded or annulled or such
indebtedness is not discharged within 30 days after written notice; (v) certain
events of bankruptcy, insolvency or reorganization of the Company or FNBC; and
(vi) 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 immediately preceding paragraph, the
Company 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
 
                                       14
<PAGE>
 
such Senior Securities for principal, premium, if any, and interest. The
Senior Indenture further provides that if the Company fails to pay such amount
forthwith upon such demand, such Trustee may, among other things, institute a
judicial proceeding for the collection thereof.
 
  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.
 
  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.
 
  The Company is required to file annually with the Trustees a written
statement of officers as to the existence or non-existence of defaults under
the Senior Indenture or the Senior Securities.
 
REGARDING MARINE MIDLAND
 
 Marine Midland, the Trustee under the Senior Indenture, has its principal
corporate trust office at 140 Broadway, 12th Floor, New York, New York 10005.
The Company has normal banking relationships with Marine Midland.
 
                            SUBORDINATED SECURITIES
 
  The Subordinated Securities will be direct, unsecured obligations of the
Company and will be subject to the subordination provisions described below.
 
SUBORDINATION
 
  It is the intent of the Company that Subordinated Securities issued by the
Company be treated as capital for calculation of regulatory capital ratios.
The Federal Reserve Board ~ 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 Subordination Interpretations.
Subordinated debt of the Company 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 the Company 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
 
                                      15
<PAGE>
 
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 the Company 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 the Company 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 the Company 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 Indebtedness (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 rights of 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 the Company applicable to Senior Indebtedness.
Subject to payment in full of all General Obligations, the rights of 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 the Company applicable to such
creditors in respect of General Obligations.
 
  Senior Indebtedness is defined in the Subordinated Indenture as the principal
of, premium, if any, and interest on (i) all of the Company's indebtedness for
money borrowed, other than the subordinated securities issued under the
Subordinated Indenture, the Company's Floating Rate Subordinated Capital Notes
Due December 1996, the Company's 9 7/8% Subordinated Notes Due July 1999, the
Company's 9% Subordinated Notes Due June 15, 1999, the Company's 9 7/8%
Subordinated Notes Due August 15, 2000, the Company's 11 1/4% Subordinated
Notes Due February 20, 2001, the Company's 10 1/4% Subordinated Notes Due May
1, 2001, the Company's 9 1/4% Subordinated Notes Due November 15, 2001, the
Company's 8 7/8% Subordinated Notes Due March 15, 2002, the Company's 8 1/4%
Subordinated Notes Due June 15, 2002, the Company's 9 1/5% Subordinated Notes
Due December 17, 2001, the Company's 7 5/8% Subordinated Notes Due January 15,
2003 (the "January 2003 Notes"), the Company's 6 7/8% Subordinated Notes Due
June 15, 2003
 
                                       16
<PAGE>
 
(the "June 2003 Notes"), the Company's Floating Rate Subordinated Notes Due
July 28, 2003 (the "July 2003 Notes") and the Company's 6 3/8% Subordinated
Notes Due January 30, 2009 (the "January 2009 Notes") (collectively, all of the
foregoing notes are hereinafter referred to as 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, the Company 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 the Company.
 
  The January 2003 Notes, the June 2003 Notes, the July 2003 Notes and the
January 2009 Notes all constitute New Subordinated Securities; all other
Existing Subordinated Indebtedness constitutes 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 the Company 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 the Company 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 Board
(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 1978, as amended to the date of the Subordinated
Indenture.
 
  As of December 31, 1994, the aggregate amount of Senior Indebtedness and
General Obligations of the Company was approximately $1.9 billion.
 
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 or reorganization
of the Company. 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 the Company 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 the Company. Such payment may also be accelerated in the case of certain
events of insolvency or receivership of FNBC.

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 or reorganization of the Company 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 the Company in the Subordinated Indenture with respect
to Subordinated Securities of such series and continuance of such default for
60 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 Chase, as 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,
Chase 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, the Company will, upon demand of Chase, 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 the Company fails
to pay such amount forthwith upon such demand, Chase 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.
 
  The Company is required to file annually with Chase a written statement of
officers as to the existence or non-existence of defaults under the
Subordinated Indenture or the Subordinated Securities.
 
REGARDING CHASE
 
  Chase, the Trustee under the Subordinated Indenture, has a principal
corporate trust office at 4 Chase MetroTech Center, New York, New York 11245.
The Company has normal banking relationships with Chase.

                         DESCRIPTION OF DEBT WARRANTS
 
  The Company may issue Debt Warrants for the purchase of Debt Securities.
Debt Warrants may be issued independently or together with any Debt Securities
offered by any Prospectus Supplement and may be attached to or separate from
such Debt Securities. The Debt Warrants are to be issued under warrant
agreements (each a "Debt Warrant Agreement") to be entered into between the
Company and a warrant agent which will be designated in the applicable
Prospectus Supplement (the "Debt Warrant Agent"), all as set forth in the
Prospectus Supplement relating to the particular issue of Debt Warrants (the
"Offered Debt Warrants"). The Debt Warrant Agent will act solely as an agent
of the Company in connection with the Debt Warrants and will not assume any
obligation or relationship of agency or trust for or with any holders or
beneficial owners of Debt Warrants. The following summaries of certain
provisions of the form of Debt Warrant Agreement and the warrant certificates
representing the Debt Warrants (the "Debt Warrant Certificates"), if any, do
not purport to be complete and are subject to, and are qualified in their
entirety by reference to, all the provisions of the Debt Warrant Agreement and
the Debt Warrant Certificates, respectively, including the definitions therein
of certain terms, which Agreement and Certificates will be filed as exhibits
to or incorporated by reference in the Registration Statement of which this
Prospectus forms a part.
 
  If Debt Warrants are offered, the Prospectus Supplement will describe the
terms of the Offered Debt Warrants, the Debt Warrant Agreement relating to the
Offered Debt Warrants and the Debt Warrant Certificates representing the
Offered Debt Warrants, if any, including the following: (1) the offering
price; (2) the currency or currency unit in which the price for the Offered
Debt Warrants may be payable; (3) the designation, aggregate principal amount
and terms of the Debt Securities purchasable upon exercise of the Offered Debt
Warrants; (4) if applicable, the designation and terms of the Debt Securities
with which the Offered Debt Warrants are issued and the number of Offered Debt
Warrants issued with each such Debt Security; (5) if the Debt Securities
purchasable upon exercise of Offered Debt Warrants are denominated in a
currency or currency unit other than U.S. dollars, the denomination of such
Debt Securities and the currency or units based on or relating to currencies
(including ECU) in which the principal of, premium, if any, and interest on
such Debt Securities will be payable; (6) if applicable, the date on and after
which the Offered Debt Warrants and the related Debt Securities will be
separately transferable; (7) the principal amount of Debt Securities
purchasable upon exercise of an Offered Debt Warrant and the price at which,
and currency or currency units based on or relating to currencies (including
ECU) in which, such principal amount of Debt Securities may be purchased upon
such exercise; (8) the date on which the right to exercise the Offered Debt
Warrants shall commence and the date on which such right shall expire; (9) if
applicable, a discussion of certain Federal income tax, accounting and other
special considerations, procedures and limitations; (10) whether the Debt
Warrants represented by the Debt Warrant Certificates will be issued as
Registered Securities or Bearer Securities; and (11) any other terms of the
Offered Debt Warrants, including terms, procedures and limitations relating to
the exchange and exercise of the Offered Debt Warrants.
 
                       DESCRIPTION OF CURRENCY WARRANTS
 
  The Company may issue Currency Warrants which, upon exercise at a permitted
time or times in the future, entitle any holder thereof to receive the Cash
Settlement Value (as defined below) of two designated currencies. Currency
Warrants may be issued independently or together with any Debt Securities
offered by any Prospectus Supplement and may be attached to or separate from
such Debt Securities. The Currency Warrants are to be issued under warrant
agreements (each a "Currency Warrant Agreement") to be entered into between
the Company and a warrant agent which will be designated in the applicable
Prospectus Supplement (the "Currency Warrant Agent"), all as set forth in the
Prospectus Supplement relating to the particular issue of Currency Warrants
(the "Offered Currency Warrants"). The Currency Warrant Agent will act solely
as an agent of the Company in connection with the Currency Warrants and will
not assume any obligation or relationship of agency or trust for or with any
holder or beneficial owners of Currency Warrants. The following summaries of
certain provisions of the form of Currency Warrant Agreement do
 
                                      19
<PAGE>
 
not purport to be complete and are subject to and are qualified in their
entirety by reference to all the provisions of the Currency Warrant Agreement
and the form of certificate, if any, representing the Currency Warrants (the
"Currency Warrant Certificates"), respectively, including the definitions
therein of certain terms which Agreement and Certificate, if any, will be filed
as an exhibit to or incorporated by reference in the Registration Statement of
which this Prospectus forms a part.
 
  The Currency Warrants will not require, or entitle, any holder thereof to
sell any foreign currency to the Company. The Company will make only a U.S.
dollar cash settlement upon exercise of a Currency Warrant and will not be
obligated to purchase or take delivery of any foreign currency from any holder
of a Currency Warrant.
 
  The "Cash Settlement Value" of an exercised Currency Warrant will be an
amount stated in U.S. dollars which is the greater of (i) zero and (ii) an
amount equal to (a) the nominal amount of such Currency Warrant, minus (b) an
amount equal to the nominal amount of such Currency Warrant times a fraction,
the numerator of which is the Strike Price of such Currency Warrant and the
denominator of which is the Spot Rate of such Currency Warrant on the Exercise
Date. The "nominal amount" of a Currency Warrant refers to the principal
amount, expressed in U.S. dollars, of a currency (the "Base Currency") which is
to be compared to another currency (the "Second Currency") upon exercise of
such Currency Warrant. Unless otherwise specified in the applicable Prospectus
Supplement, the Base Currency shall be U.S. dollars. The "Strike Price" is the
designated rate of exchange of the Base Currency for the Second Currency which
the Company will specify in the Prospectus Supplement relating to the Offered
Currency Warrants. The "Spot Rate" refers to the floating rate of exchange of
the Base Currency for the Second Currency on any given date, as quoted by a
reference bank or banks or other institution at a designated time of day, such
source of quotations and time to be specified in the applicable Prospectus
Supplement. The "Exercise Date" refers to the effective date on which the
holder of a Currency Warrant exercises such Currency Warrant.
 
  If Currency Warrants are offered, the Prospectus Supplement will describe the
terms of the Offered Currency Warrants, the Currency Warrant Agreement relating
to the Offered Currency Warrants and, if applicable, Currency Warrant
Certificates, including the following: (1) the aggregate number of Offered
Currency Warrants; (2) the Nominal Amount of each Offered Currency Warrant; (3)
the price of the Offered Currency Warrants; (4) the Base Currency and the
Second Currency; (5) the Strike Price for the Offered Currency Warrants; (6)
the reference bank or banks or other institution and time of day to be used to
determine the Spot Rate; (7) the date on which the right to exercise the
Offered Currency Warrants shall begin and the date on which such right shall
terminate; (8) if applicable, the minimum or maximum amount of Offered Currency
Warrants which may be exercised at any one time; (9) the place or places at
which payment of the Cash Settlement Value is to be made by the Company; (10)
whether the Offered Currency Warrants will be represented by certificates or
issued in book-entry form; (11) the method by which the Offered Currency
Warrants are to be exercised; (12) the Federal income tax consequences and
other special considerations, procedures and limitations applicable to such
Offered Currency Warrants; and (13) any other terms of the Offered Currency
Warrants, including risk factors specifically relating to the Base Currency or
Second Currency and Currency Warrants relating to such currencies.
 
                      DESCRIPTION OF STOCK-INDEX WARRANTS
 
  The Company may issue Stock Index Warrants which, upon exercise at a
permitted time or times in the future, entitle any holder thereof to receive an
amount of cash determined by references to increases and/or decreases in the
level of a specified stock index. Stock-Index Warrants may be issued
independently or together with other Securities offered by any Prospectus
Supplement and may be attached to or separate from such other Securities. The
Stock-Index Warrants are to be issued under one or more warrant agreements
(each a "Stock-Index Warrant Agreement") to be entered into between the Company
and a bank or trust company, as stock-index warrant agent which will be
designated in the applicable Prospectus Supplement (the "Stock-Index Warrant
Agent"), all as set forth in the Prospectus Supplement relating to the
particular
 
                                       20
<PAGE>
 
issue of Stock-Index Warrants. The Stock-Index Warrant Agent will act solely as
an agent of the Company in connection with the Stock-Index Warrants and will
not assume any obligation or relationship of agency or trust for or with any
holder or beneficial owners of Stock-Index Warrants. The following summaries of
certain provisions of the form of Stock-Index Warrant Agreement and form of
certificate, if any, representing the Stock-Index Warrants (the "Stock-Index
Warrant Certificates") do not purport to be complete and are subject to, and
are qualified in their entirety by reference to, all the provisions of the
Stock-Index Warrant Agreement and the Stock-Index Warrant Certificates,
respectively, including the definitions therein of certain terms which
Agreement and Certificate, if any, will be filed as an exhibit to or
incorporated by reference in the Registration Statement of which this
Prospectus forms a part.
 
  The Company may issue Stock-Index Warrants either in the form of Stock-Index
Put Warrants entitling the holders thereof to receive from the Company the
Stock-Index Cash Settlement Value (as described in the applicable Prospectus
Supplement) in U.S. dollars, which amount will be determined by reference to
the amount, if any, by which the Stock-Index Exercise Price (as described in
the applicable Prospectus Supplement) exceeds the closing value of the Index on
the valuation date (the "Index Value") at the time of exercise, or in the form
of Stock-Index Call Warrants entitling the holders thereof to receive from the
Company the Stock-Index Cash Settlement Value in U.S. dollars, which amount
will be determined by reference to the amount, if any, by which the Index Value
at the time of exercise exceeds the Stock-Index Exercise Price.
 
  The Prospectus Supplement for an issue of Stock-Index Warrants will set forth
the formula pursuant to which the Stock-Index Cash Settlement Value will be
determined. In addition, if so specified in the applicable Prospectus
Supplement, following the occurrence of a Market Disruption Event (as defined
therein), the Stock-Index Cash Settlement Value may be determined on a
different basis than under normal exercise of a Stock-Index Warrant.
 
  Unless otherwise indicated in the Prospectus Supplement, a Stock-Index
Warrant will be settled only in cash and, accordingly, will not require or
entitle a holder thereof to sell, deliver, purchase or take delivery of any
shares of any underlying stock or any other securities. The holders will not be
entitled to any of the rights of the holders of any underlying stock.
 
  If Stock-Index Warrants are offered, the Prospectus Supplement will describe
the terms of Stock-Index Warrants offered thereby, including the following: (1)
whether such Stock-Index Warrants are Stock-Index Put Warrants, Stock-Index
Call Warrants or both; (2) the aggregate amount of such Stock-Index Warrants;
(3) the offering price; (4) the stock index for such Stock-Index Warrants,
which may be based on one or more U.S. or foreign stocks or a combination
thereof and may be a preexisting U.S. or foreign stock index compiled and
published by a third party or an index based on one or more underlying stock or
stocks selected by the Company solely in connection with the issuance of such
Stock-Index Warrants, and certain information regarding such stock index and
the underlying stock or stocks; (5) the date on which the right to exercise
such Stock-Index Warrants commences and the date on which such right expires
(the "Stock-Index Warrant Expiration Date"); (6) the procedures and conditions
relating to exercise; (7) the circumstances, if any, which will cause the
Stock-Index Warrants to be deemed to be automatically exercised; (8) the
minimum number, if any, of Stock-Index Warrants to be exercised at any one time
other than upon automatic exercise and any other restrictions on exercise; (9)
the maximum number, if any, of such Stock-Index Warrants that may, subject to
the Company's election, be exercised by all owners (or by any person or entity)
on any day; (10) the method of providing for a substitute index or otherwise
determining the amount payable in connection with the exercise of such Stock-
Index Warrants if the stock index changes or ceases to be made available by its
publisher, which determination will be made by an independent expert; (11) the
national securities exchange on which the Stock-Index Warrants will be listed,
if any; (12) whether the Stock-Index Warrants will be issued in certificated or
book-entry form; (13) the place or places at which payment of the Stock-Index
Cash Settlement Value is to be made by the Company; (14) information with
respect to book-entry procedures, if any; (15) the plan of distribution of such
Stock-Index Warrants; (16) the identity of the Stock-Index Warrant Agent; (17)
any provisions permitting a holder of a Stock-Index Warrant to condition
 
                                       21
<PAGE>
 
a stock-index exercise notice on the absence of certain specified changes in
the Index Value after the Stock-Index Warrant Exercise Date; and (18) any other
terms of such Stock-Index Warrants, including risk factors specifically
relating to fluctuations in the applicable stock index and possible illiquidity
in the secondary market.
 
  Prospective purchasers of Stock-Index Warrants should be aware that special
U.S. Federal income tax, accounting and other considerations may be applicable
to instruments such as Stock-Index Warrants. The Prospectus Supplement relating
to any issue of Stock-Index Warrants will describe such considerations.
 
                         DESCRIPTION OF OTHER WARRANTS
 
  The Company may issue Other Warrants, if permitted under applicable law, to
buy or sell debt securities of or guaranteed by the United States, to buy or
sell a commodity or a unit of a commodity index or to buy or sell some other
item or unit of an index other than indices covered by Stock-Index Warrants
(collectively, "Exercise Items"). Owners of Other Warrants will be entitled to
receive from the Company the cash settlement value in U.S. dollars of the right
to buy or sell the Exercise Items (the "Other Warrant Cash Settlement Value").
An Owner of Other Warrants will receive a cash payment upon exercise only if
the Other Warrants have an Other Warrant Cash Settlement Value in excess of
zero at that time.
 
  Other Warrants may be issued independently or together with other Securities
offered by any Prospectus Supplement and may be attached to or separate from
such other Securities. The Other Warrants are to be issued under one or more
other warrant agreements (the "Other Warrant Agreements") to be entered into
between the Company and a bank or trust company, as warrant agent which will be
designated in the applicable Prospectus Supplement (the "Other Warrant Agent"),
all as set forth in the Prospectus Supplement relating to the particular issue
of Other Warrants. The Other Warrant Agent will act solely as an agent of the
Company in connection with the Other Warrants and will not assume any
obligation or relationship of agency or trust for or with any holder or
beneficial owners of the Other Warrants. The following summaries of certain
provisions of the form of Other Warrant Agreement and form of certificate, if
any, representing the Other Warrants (the "Other Warrant Certificates") do not
purport to be complete and are subject to, and are qualified in their entirety
by reference to, all the provisions of the Other Warrant Agreement and the
Other Warrant Certificates, respectively, including the definitions therein of
certain terms which Agreement and Certificate, if any, will be filed as an
exhibit to or incorporated by reference in the Registration Statement of which
this Prospectus forms a part.
 
  Unless otherwise indicated in the Prospectus Supplement, an Other Warrant
will be settled only in cash, in U.S. dollars, and accordingly, will not
require or entitle an owner thereof to sell, deliver, purchase or take delivery
of any Exercise Items.
 
  If Other Warrants are offered, the applicable Prospectus Supplement will
describe the terms of such Other Warrants, including, where applicable, the
following: (1) the title and aggregate number of such Other Warrants; (2) the
offering price; (3) the Exercise Items that such Other Warrants represent the
right to buy or sell; (4) the procedures and conditions relating to exercise;
(5) the date on which the right to exercise the Other Warrants shall commence
and the date such right shall expire (the "Other Warrant Expiration Date"); (6)
the method of determining the Other Warrant Cash Settlement Value; (7) whether
such Other Warrants will be issued in certificated or book-entry form; (8)
whether such Other Warrants will be listed on a national securities exchange;
(9) information with respect to book-entry procedures, if any; (10) the
identity of the Other Warrant Agent; and (11) any other terms of such Other
Warrants, including risk factors relating to significant fluctuations in the
market for the applicable Exercise Item, the potential illiquidity of the
secondary market and the risk that the Other Warrants may expire worthless.
 
                                       22
<PAGE>
 
  Prospective purchasers of Other Warrants should be aware that special U.S.
Federal income tax, accounting and other considerations may be applicable to
instruments such as Other Warrants. The Prospectus Supplement relating to any
issue of Other Warrants will describe such considerations.
 
                       DESCRIPTION OF THE PREFERRED STOCK
 
  The following description of the terms of the Preferred Stock sets forth
certain general terms and provisions of the Preferred Stock to which any
Prospectus Supplement may relate. Certain other terms of any series of
Preferred Stock offered by any Prospectus Supplement will be specified in the
applicable Prospectus Supplement. If so specified in the applicable Prospectus
Supplement, the terms of any series of Preferred Stock may differ from the
terms set forth below. The description of the terms of the Preferred Stock set
forth below and in any Prospectus Supplement does not purport to be complete
and is subject to and qualified in its entirety by reference to the Certificate
of Designation relating to the applicable series of Preferred Stock, which
Certificate will be filed as an exhibit to or incorporated by reference in the
Registration Statement of which this Prospectus forms a part.
 
GENERAL
 
  Pursuant to the Company's Restated Certificate of Incorporation, the Board of
Directors of the Company has the authority, without further stockholder action,
to issue from time to time a maximum of 15,000,000 shares of preferred stock,
without par value, in one or more series and for such consideration, as may be
fixed from time to time by the Board of Directors of the Company, and to fix
before the issuance of any shares of preferred stock of a particular series,
the designation of such series, the number of shares to comprise such series,
the dividend rate or rates payable with respect to the shares of such series,
the redemption price or prices, if any, and the terms and conditions of the
redemption, the voting rights, any sinking fund provisions for the redemption
or purchase of the shares of such series, the terms and conditions upon which
the shares are convertible, if they are convertible, and any other relative
rights, preferences and limitations pertaining to such series. As of December
31, 1994, there were issued and outstanding 2,410,000 shares of the Company's
Preferred Stock with Cumulative and Adjustable Dividends ($50 stated value)
(the "Series A Preferred Stock"), 1,191,000 shares of the Company's Preferred
Stock with Cumulative and Adjustable Dividends, Series B ($100 stated value)
(the "Series B Preferred Stock"), 713,800 shares of the Company's Preferred
Stock with Cumulative and Adjustable Dividends, Series C ($100 stated value)
(the "Series C Preferred Stock"), 160,000 shares of the Company's 8.45%
Cumulative Preferred Stock, Series E ($625 stated value) (the "Series E
Preferred Stock"), and 40,000 shares of the Company's 5 3/4% Cumulative
Convertible Preferred Stock, Series B ($5,000 stated value) (the "Series B
Convertible Preferred Stock") (collectively, the "Existing Preferred Stock").
See "Description of Existing Preferred Stock" herein.
 
  As described under "Description of Depositary Shares" below, the Company may,
at its option, elect to offer depositary shares ("Depositary Shares") evidenced
by depositary receipts, each representing a fraction (to be specified in the
Prospectus Supplement relating to the particular series of Preferred Stock) of
a share of the particular series of the Preferred Stock issued and deposited
with a depositary, in lieu of offering full shares of such series of the
Preferred Stock.
 
  Under interpretations adopted by the Federal Reserve Board, if the holders of
Preferred Stock of any series become entitled to vote for the election of
directors because dividends on such series are in arrears as described under
"Voting Rights" below, such series may then be deemed a "class of voting
securities" and a holder of 25% or more of such series (or a holder of 5% or
more if it otherwise exercises a "controlling influence" over the Company) may
then be subject to regulation as a bank holding company in accordance with the
Bank Holding Company Act of 1956, as amended. In addition, at such time as such
series is deemed a class of voting securities, any other bank holding company
may be required to obtain the prior approval of the Federal Reserve Board to
acquire 5% or more of such series, and any person other than a bank holding
 
                                       23
<PAGE>
 
company may be required to obtain the prior approval of the Federal Reserve
Board to acquire 10% or more of such series.
 
  The Preferred Stock shall have the dividend, liquidation, redemption, voting
and conversion rights set forth below unless otherwise specified in the
applicable Prospectus Supplement. Reference is made to the Prospectus
Supplement relating to the particular series of Preferred Stock offered thereby
for specific terms, including: (1) the designation, stated value and
liquidation preference of such Preferred Stock and the number of shares
offered; (2) the initial public offering price at which such shares will be
issued; (3) the dividend rate or rates (or method of calculation), the dividend
periods, the date on which dividends shall be payable and whether such
dividends shall be cumulative or noncumulative and, if cumulative, the dates
from which dividends shall commence to cumulate; (4) any redemption or sinking
fund provisions; (5) any conversion provisions; (6) whether the Company has
elected to offer Depositary Shares as described below under "Description of
Depositary Shares"; and (7) any additional dividend, liquidation, redemption,
sinking fund and other rights, preferences, privileges, limitations and
restrictions of such Preferred Stock.
 
  The Preferred Stock will, when issued, be fully paid and nonassessable.
Unless otherwise specified in the applicable Prospectus Supplement, the shares
of each series of Preferred Stock will upon issuance rank on a parity in all
respects with the Company's Existing Preferred Stock, described below, and each
other then outstanding series of preferred stock of the Company. The Preferred
Stock will have no preemptive rights to subscribe for any additional securities
which may be issued by the Company. Unless otherwise specified in the
applicable Prospectus Supplement, First Chicago Trust Company of New York will
be the transfer agent and registrar for the Preferred Stock.
 
  Because the Company is a holding company, its rights and the rights of
holders of its securities, including the holders of Preferred Stock, to
participate in the assets of any Company subsidiary upon the latter's
liquidation or recapitalization will be subject to the prior claims of such
subsidiary's creditors and preferred shareholders, except to the extent the
Company may itself be a creditor with recognized claims against such subsidiary
or a holder of preferred shares of such subsidiary.
 
DIVIDENDS
 
  The holders of the Preferred Stock will be entitled to receive, when, as and
if declared by the Board of Directors of the Company, out of funds legally
available therefor, dividends at such rates and on such dates as will be
specified in the applicable Prospectus Supplement. Such rates may be fixed or
variable or both. If variable, the formula used for determining the dividend
rate for each dividend period will be specified in the applicable Prospectus
Supplement. Dividends will be payable to the holders of record as they appear
on the stock books of the Company (or, if applicable, the records of the
Depositary referred to below under "Description of Depositary Shares") on such
record dates as will be fixed by the Board of Directors of the Company.
Dividends may be paid in the form of cash, Preferred Stock (of the same or a
different series) or Common Stock of the Company, in each case as specified in
the applicable Prospectus Supplement.
 
  Dividends on any series of Preferred Stock may be cumulative or
noncumulative, as specified in the applicable Prospectus Supplement. If the
Board of Directors of the Company fails to declare a dividend payable on a
dividend payment date on any Preferred Stock for which dividends are
noncumulative ("Noncumulative Preferred Stock"), then the holders of such
Preferred Stock will have no right to receive a dividend in respect of the
dividend period relating to such dividend payment date, and the Company will
have no obligation to pay the dividend accrued for such period, whether or not
dividends on such Preferred Stock are declared or paid on any future dividend
payment dates.
 
  The Company shall not declare or pay or set apart for payment any dividends
on any series of its preferred shares ranking, as to dividends, on a parity
with or junior to the outstanding Preferred Stock of any series unless (i) if
such Preferred Stock has a cumulative dividend ("Cumulative Preferred Stock"),
full cumulative dividends have been or contemporaneously are declared and paid
or declared and a sum sufficient
 
                                       24
<PAGE>
 
for the payment thereof set apart for such payment on such Preferred Stock for
all dividend periods terminating on or prior to the date of payment of any such
dividends on such other series of preferred shares of the Company, or (ii) if
such Preferred Stock is Noncumulative Preferred Stock, full dividends for the
then-current dividend period on such Preferred Stock have been or
contemporaneously are declared and paid or declared and a sum sufficient for
the payment thereof set apart for such payment. When dividends are not paid in
full upon Preferred Stock of any series and any other shares of preferred stock
of the Company ranking on a parity as to dividends with such Preferred Stock,
all dividends declared upon such Preferred Stock and any other preferred shares
of the Company ranking on a parity as to dividends with such Preferred Stock
shall be declared pro rata so that the amount of dividends declared per share
on such Preferred Stock and such other shares shall in all cases bear to each
other the same ratio that the accrued dividends per share on such Preferred
Stock (which shall not, if such Preferred Stock is Noncumulative Preferred
Stock, include any accumulation in respect of unpaid dividends for prior
dividend periods) and such other preferred shares bear to each other. Except as
set forth in the preceding sentence, unless full dividends on the outstanding
Cumulative Preferred Stock of any series have been paid for all past dividend
periods and full dividends for the then-current dividend period on the
outstanding Noncumulative Preferred Stock of any series have been declared and
paid or declared and a sum sufficient for the payment thereof set apart for
such payment, no dividends (other than in Common Stock of the Company or other
shares of the Company ranking junior to such Preferred Stock as to dividends
and upon liquidation) shall be declared or paid or set aside for payment, nor
shall any other distribution be made on the Common Stock of the Company or on
any other shares of the Company ranking junior to or on a parity with such
Preferred Stock as to dividends or upon liquidation. Unless full dividends on
the Cumulative Preferred Stock of any series have been paid for all past
dividend periods and full dividends for the then-current dividend period on the
Noncumulative Preferred Stock of any series have been declared and paid or
declared and a sum sufficient for the payment thereof set apart for such
payment, no Common Stock or any other shares of the Company ranking junior to
or on a parity with such Preferred Stock as to dividends or upon liquidation
shall be redeemed, purchased or otherwise acquired for any consideration (or
any moneys be paid or made available for a sinking fund for the redemption of
any such shares) by the Company or any subsidiary of the Company except by
conversion into or exchange for shares of the Company ranking junior to such
Preferred Stock as to dividends and upon liquidation.
 
REDEMPTION
 
  A series of the Preferred Stock may be redeemable, in whole or in part, at
the option of the Company, and may be subject to mandatory redemption pursuant
to a sinking fund or otherwise, in each case upon terms, at the times and at
the redemption prices specified in the applicable Prospectus Supplement and
subject to the rights of holders of other securities of the Company. Preferred
Stock redeemed by the Company will be restored to the status of authorized but
unissued preferred shares.
 
  The Prospectus Supplement relating to a series of Preferred Stock that is
subject to mandatory redemption will specify the number of shares of such
Preferred Stock that shall be redeemed by the Company in each year commencing
after a date to be specified, at a redemption price per share to be specified,
together with an amount equal to all accrued and unpaid dividends thereon
(which shall not, if such Preferred Stock is Noncumulative Preferred Stock,
include any accumulation in respect of unpaid dividends for prior dividend
periods) to the date of redemption. The redemption price may be payable in cash
or other property, as specified in the applicable Prospectus Supplement. If the
redemption price for Preferred Stock of any series is payable only from the net
proceeds of the issuance of capital stock of the Company, the terms of such
Preferred Stock may provide that, if no such capital stock shall have been
issued or to the extent the net proceeds from any issuance are insufficient to
pay in full the aggregate redemption price then due, such Preferred Stock shall
automatically and mandatorily be converted into shares of the applicable
capital stock of the Company pursuant to conversion provisions specified in the
applicable Prospectus Supplement.
 
  If fewer than all the outstanding shares of Preferred Stock of any series are
to be redeemed, the number of shares to be redeemed will be determined in a
manner designated by the Board of Directors of the Company
 
                                       25
<PAGE>
 
and such shares shall be redeemed pro rata from the holders of record of such
shares in proportion to the number of such shares held by such holders (with
adjustments to avoid redemption of fractional shares) or by lot or by any other
method as may be determined by the Board of Directors of the Company.
 
  Notwithstanding the foregoing, if any dividends, including any accumulation,
on Cumulative Preferred Stock of any series are in arrears, no Preferred Stock
of such series shall be redeemed unless all outstanding Preferred Stock of such
series is simultaneously redeemed, and the Company shall not purchase or
otherwise acquire any Preferred Stock of such series; provided, however, that
the foregoing shall not prevent the purchase or acquisition of Preferred Stock
of such series pursuant to a purchase or exchange offer provided such offer is
made on the same terms to all holders of the Preferred Stock of such series.
 
  Notice of redemption shall be given by mailing the same to each record holder
of the Preferred Stock to be redeemed, not less than 30 nor more than 60 days
prior to the date fixed for redemption thereof, to the respective addresses of
such holders as the same shall appear on the stock books of the Company. Each
notice shall state: (i) the redemption date; (ii) the number of shares and
series of the Preferred Stock to be redeemed; (iii) the redemption price; (iv)
the place or places where certificates for such Preferred Stock are to be
surrendered for payment of the redemption price; (v) that dividends on the
shares to be redeemed will cease to accrue on such redemption date; and (vi)
the date upon which the holder's conversion rights, if any, as to such shares,
shall terminate. If fewer than all the shares of Preferred Stock of any series
held by any holder are to be redeemed, the notice mailed to such holder shall
also specify the number of shares of Preferred Stock to be redeemed from such
holder.
 
  If notice of redemption of any shares of Preferred Stock has been given, from
and after the redemption date for such shares (unless default shall be made by
the Company in providing money for the payment of the redemption price of such
shares), dividends on such shares shall cease to accrue and such shares shall
no longer be deemed to be outstanding, and all rights of the holders thereof as
shareholders of the Company (except the right to receive the redemption price)
shall cease. Upon surrender in accordance with such notice of the certificates
representing any such shares (properly endorsed or assigned for transfer, if
the Board of Directors of the Company shall so require and the notice shall so
state), the redemption price set forth above shall be paid out of the funds
provided by the Company. If fewer than all the shares represented by any such
certificate are redeemed, a new certificate shall be issued representing the
unredeemed shares without cost to the holder thereof.
 
CONVERSION RIGHTS
 
  The Prospectus Supplement relating to a series of the Preferred Stock that is
convertible will state the terms on which shares of such series are convertible
into the Company's Common Stock, or another series of Preferred Stock.
 
RIGHTS UPON LIQUIDATION
 
  In the event of any voluntary or involuntary liquidation, dissolution or
winding up of the Company, the holders of Preferred Stock shall be entitled to
receive out of the assets of the Company available for distribution to
shareholders, before any distribution of assets is made to holders of Common
Stock or any other class or series of shares ranking junior to such Preferred
Stock upon liquidation, liquidating distributions in the amount of the
liquidation preference of such Preferred Stock plus accrued and unpaid
dividends (which shall not, if such Preferred Stock is Noncumulative Preferred
Stock, include any accumulation in respect of unpaid dividends for prior
dividend periods). If, upon any voluntary or involuntary liquidation,
dissolution or winding up of the Company the amounts payable with respect to
Preferred Stock of any series and any other shares of the Company ranking as to
any such distribution on a parity with such Preferred Stock are not paid in
full, the holders of such Preferred Stock and of such other shares will share
ratably in any such distribution of assets of the Company in proportion to the
full respective preferential amounts to which they are entitled. After payment
of the full amount of the liquidating distribution to which
 
                                       26
<PAGE>
 
they are entitled, the holders of Preferred Stock of any series will not be
entitled to any further participation in any distribution of assets by the
Company.
 
VOTING RIGHTS
 
  Except as indicated below or in the applicable Prospectus Supplement, or
except as expressly required by applicable law, the holders of the Preferred
Stock will not be entitled to vote. In the event the Company issues full shares
of any series of Preferred Stock, each such share will be entitled to one vote
on matters on which holders of such series of the Preferred Stock are entitled
to vote. However, as more fully described under "Description of Depositary
Shares" below, if the Company elects to issue Depositary Shares representing a
fraction of a share of a series of Preferred Stock, each such Depositary Share
will, in effect, be entitled to such fraction of a vote, rather than a full
vote, per Depositary Share. Since each full share of any series of Preferred
Stock of the Company shall be entitled to one vote, the voting power of such
series, on matters on which holders of such series and holders of other series
of Preferred Stock are entitled to vote as a single class, shall depend on the
number of shares in such series, not the aggregate stated value, liquidation
preference or initial offering price of the shares of such series of Preferred
Stock.
 
  If the equivalent of six quarterly dividends payable on any series of
Preferred Stock are in default, the number of directors of the Company will be
increased by two and the holders of all outstanding series of Preferred Stock,
voting as a single class without regard to series, will be entitled to elect
such additional two directors until all dividends in default have been paid or
declared and set apart for payment.
 
  The affirmative vote or consent of the holders of at least 66 2/3 percent of
the outstanding shares of Preferred Stock of any series, voting as a class,
will be required for any amendment to the Company's Certificate of
Incorporation (or any certificate supplemental thereto) that will adversely
affect the powers, preferences, privileges or rights of the Preferred Stock of
such series. The affirmative vote or consent of the holders of at least 66 2/3
percent of the outstanding shares of Preferred Stock of any series and any
other series of preferred shares of the Company ranking on a parity with the
Preferred Stock of such series as to dividends or upon liquidation, voting as a
single class without regard to series, will be required to authorize, effect or
validate the creation, authorization or issue of any shares of any class of
stock of the Company ranking prior to the Preferred Stock of such series as to
dividends or upon liquidation, or the reclassification of any authorized stock
of the Company into any such prior shares, or the creation, authorization or
issue of any obligation or security convertible into or evidencing the right to
purchase any such prior shares.
 
  Subject to such affirmative vote or consent of the holders of the outstanding
shares of Preferred Stock of any series, the Company may, by resolution of its
Board of Directors or as otherwise permitted by law, from time to time alter or
change the preferences, rights or powers of the Preferred Stock of such series.
The holders of the Preferred Stock of such series shall not be entitled to
participate in any such vote if, at or prior to the time when any such
alteration or change is to take effect, provision is made for the redemption of
all the Preferred Stock of such series at the time outstanding. Nothing in this
section shall be taken to require a class vote or consent in connection with
the authorization, designation, increase or issuance of any shares of any class
or series (including additional Preferred Stock of any series) that rank junior
to or on a parity with the Preferred Stock of such series as to dividends and
liquidation rights or in connection with the authorization, designation,
increase or issuance of any bonds, mortgages, debentures or other obligations
of the Company.
 
                        DESCRIPTION OF DEPOSITARY SHARES
 
GENERAL
 
  The Company may, at its option, elect to offer fractional shares of Preferred
Stock, rather than full shares of Preferred Stock. In the event such option is
exercised, the Company will issue to the public receipts for
 
                                       27
<PAGE>
 
Depositary Shares, each of which will represent a fraction (to be set forth in
the Prospectus Supplement relating to a particular series of Preferred Stock)
of a share of a particular series of Preferred Stock as described below.
 
  The shares of any series of Preferred Stock represented by Depositary Shares
will be deposited under a Deposit Agreement (the "Deposit Agreement") between
the Company and a bank or trust company selected by the Company having its
principal office in the United States and having a combined capital and surplus
of at least $50,000,000 (the "Depositary"). Subject to the terms of the Deposit
Agreement, each owner of a Depositary Share will be entitled, in proportion to
the applicable fraction of a share of Preferred Stock represented by such
Depositary Share, to all the rights and preferences of the Preferred Stock
represented thereby (including dividend, voting, redemption, conversion and
liquidation rights).
 
  The Depositary Shares will be evidenced by depositary receipts issued
pursuant to the Deposit Agreement ("Depositary Receipts"). Depositary Receipts
will be distributed to those persons purchasing the fractional shares of
Preferred Stock in accordance with the terms of the offering. Copies of the
forms of Deposit Agreement and Depositary Receipt will be filed as exhibits to,
or incorporated by reference in, the Registration Statement of which this
Prospectus is a part, and the following summary is qualified in its entirety by
reference to such exhibits.
 
  Pending the preparation of definitive engraved Depositary Receipts, the
Depositary may, upon the written order of the Company, issue temporary
Depositary Receipts substantially identical to (and entitling the holders
thereof to all the rights pertaining to) the definitive Depositary Receipts but
not in definitive form. Definitive Depositary Receipts will be prepared
thereafter without unreasonable delay, and temporary Depositary Receipts will
be exchangeable for definitive Depositary Receipts at the Company's expense.
 
  Upon surrender of Depositary Receipts at the principal office of the
Depositary (unless the related Depositary Shares have previously been called
for redemption), the owner of the Depositary Shares evidenced thereby is
entitled to delivery at such office, to or upon his order, of the number of
whole shares of Preferred Stock and any money or other property represented by
such Depositary Shares. Partial shares of Preferred Stock will not be issued.
If the Depositary Receipts delivered by the holder evidence a number of
Depositary Shares in excess of the number of Depositary Shares representing a
number of whole shares of Preferred Stock to be withdrawn, the Depositary will
deliver to such holder at the same time a new Depositary Receipt evidencing
such excess number of Depositary Shares. Holders of shares of Preferred Stock
thus withdrawn will not thereafter be entitled to deposit such shares under the
Deposit Agreement or to receive Depositary Shares therefor. The Company does
not expect that there will be any public trading market for withdrawn shares of
Preferred Stock.
 
DIVIDENDS AND OTHER DISTRIBUTIONS
 
  The Depositary will distribute all cash dividends or other cash distributions
received in respect of the Preferred Stock to the record holders of Depositary
Shares relating to such Preferred Stock in proportion to the numbers of such
Depositary Shares owned by such holders. The Depository shall distribute only
such amount, however, as can be distributed without attributing to any holder
of Depositary Shares a fraction of one cent, and any balance not so distributed
shall be added to and treated as part of the next sum received by the
Depositary for distribution to record holders of Depositary Shares.
 
  In the event of a distribution other than in cash, the Depositary will
distribute property received by it to the record holders of Depositary Shares
entitled thereto, unless the Depositary determines that it is not feasible to
make such distribution, in which case the Depositary may, with the approval of
the Company, sell such property and distribute the net proceeds from such sale
to such holders.
 
                                       28
<PAGE>
 
REDEMPTION OF DEPOSITARY SHARES
 
  If a series of Preferred Stock represented by Depositary Shares is subject to
redemption, the Depositary Shares will be redeemed from the proceeds received
by the Depositary resulting from the redemption, in whole or in part, of such
series of Preferred Stock held by the Depositary. The Depositary shall mail
notice of redemption not less than 30 nor more than 60 days prior to the date
fixed for redemption to the record holders of the Depositary Shares to be so
redeemed at their respective addresses appearing in the Depositary's books. The
redemption price per Depositary Share will be equal to the applicable fraction
of the redemption price per share payable with respect to such series of the
Preferred Stock. Whenever the Company redeems shares of Preferred Stock held by
the Depositary, the Depositary will redeem as of the same redemption date the
number of Depositary Shares representing shares of Preferred Stock so redeemed.
If less than all the Depositary Shares are to be redeemed, the Depositary
Shares to be redeemed will be selected by lot or pro rata as may be determined
by the Depositary.
 
  After the date fixed for redemption, the Depositary Shares so called for
redemption will no longer be deemed to be outstanding and all rights of the
holders of the Depositary Shares will cease, except the right to receive the
moneys payable upon such redemption and any money or other property to which
the holders of such Depositary Shares were entitled upon such redemption upon
surrender to the Depositary of the Depositary Receipts evidencing such
Depositary Shares.
 
VOTING THE PREFERRED STOCK
 
  Upon receipt of notice of any meeting at which the holders of the Preferred
Stock are entitled to vote, the Depositary will mail the information contained
in such notice of meeting to the record holders of the Depositary Shares
relating to such Preferred Stock. Each record holder of such Depositary Shares
on the record date (which will be the same date as the record date for the
Preferred Stock) will be entitled to instruct the Depositary as to the exercise
of the voting rights pertaining to the amount of the Preferred Stock
represented by such holder's Depositary Shares. The Depositary will endeavor,
insofar as practicable, to vote the amount of the Preferred Stock represented
by such Depositary Shares in accordance with such instructions, and the Company
will agree to take all action which may be deemed necessary by the Depositary
in order to enable the Depositary to do so. The Depositary will abstain from
voting shares of the Preferred Stock to the extent it does not receive specific
instructions from the holders of Depositary Shares representing such Preferred
Stock.
 
TAXATION
 
  Owners of the Depositary Shares will be treated for Federal income tax
purposes as if they were owners of the series of Preferred Stock represented by
such Depositary Shares and, accordingly, will be entitled to take into account
for Federal income tax purposes income and deductions to which they would be
entitled if they were holders of such series of Preferred Stock. In addition,
(i) no gain or loss will be recognized for Federal income tax purposes upon the
withdrawal of Preferred Stock in exchange for Depositary Shares as provided in
the Deposit Agreement, (ii) the tax basis of each share of Preferred Stock to
an exchanging owner of Depositary Shares will, upon such exchange, be the same
as the aggregate tax basis of the Depositary Shares exchanged therefor and
(iii) the holding period for shares of the Preferred Stock in the hands of an
exchanging owner of Depositary Shares who held such Depositary Shares as a
capital asset at the time of the exchange thereof for Preferred Stock will
include the period during which such person owned such Depositary Shares.
 
AMENDMENT AND TERMINATION OF THE DEPOSITARY AGREEMENT
 
  The form of Depositary Receipt evidencing the Depositary Shares and any
provision of the Deposit Agreement may at any time be amended by agreement
between the Company and the Depositary. However, any amendment which materially
and adversely alters the rights of the holders of Depositary Shares will not be
effective unless such amendment has been approved by the holders of at least a
majority of the Depositary
 
                                       29
<PAGE>
 
Shares then outstanding. The Deposit Agreement may be terminated by the Company
or the Depositary only if (i) all outstanding Depositary Shares have been
redeemed or (ii) there has been a final distribution in respect of the
Preferred Stock in connection with any liquidation, dissolution or winding up
of the Company and such distribution has been distributed to the holders of
Depositary Receipts.
 
CHARGES OF DEPOSITARY
 
  The Company will pay all transfer and other taxes and governmental charges
arising solely from the existence of the depositary arrangements. The Company
will pay charges of the Depositary in connection with the initial deposit of
the Preferred Stock and any redemption of the Preferred Stock. Holders of
Depositary Receipts will pay other transfer and other taxes and governmental
charges and such other charges as are expressly provided in the Deposit
Agreement to be for their accounts.
 
MISCELLANEOUS
 
  The Depositary will forward to the holders of Depositary Shares all reports
and communications from the Company which are delivered to the Depositary and
which the Company is required to furnish to the holders of the Preferred Stock.
 
  Neither the Depositary nor the Company will be liable if it is prevented or
delayed by law or any circumstance beyond its control in performing its
obligations under the Deposit Agreement. The obligations of the Company and the
Depositary under the Deposit Agreement will be limited to performance in good
faith of their duties thereunder and they will not be obligated to prosecute or
defend any legal proceeding in respect of any Depositary Shares or Preferred
Stock unless satisfactory indemnity is furnished. They may rely upon written
advice of counsel or accountants, or information provided by persons presenting
Preferred Stock for deposit, holders of Depositary Receipts or other persons
believed to be competent and on documents believed to be genuine.
 
RESIGNATION AND REMOVAL OF DEPOSITARY
 
  The Depositary may resign at any time by delivering to the Company notice of
its election to do so, and the Company may at any time remove the Depositary,
any such resignation or removal to take effect upon the appointment of a
successor Depositary and its acceptance of such appointment. Such successor
Depositary must be appointed within 60 days after delivery of the notice of
resignation or removal and must be a bank or trust company having its principal
office in the United States and having a combined capital and surplus of at
least $50,000,000.
 
                    DESCRIPTION OF EXISTING PREFERRED STOCK
 
  The outstanding Series A Preferred Stock, Series B Preferred Stock and Series
C Preferred Stock of the Company were issued in October 1982, February 1983,
and February 1984, respectively. The dividend rate on each series is adjusted
quarterly, based on a formula that considers the interest rates for selected
short- and long-term U.S. Treasury securities prevailing at the time the rate
is set. The Company's Series B Convertible Preferred Stock and Series E
Preferred Stock, which were issued in March 1993, and November 1992,
respectively, have fixed dividend rates. The Existing Preferred Stock ranks
prior to the Company's Common Stock, both as to dividends and upon liquidation,
but has no general voting rights (except as described under "Description of
Preferred Stock--Voting Rights"). Each series of the Existing Preferred Stock
ranks pari passu with each other series of the Existing Preferred Stock with
respect to dividends and liquidation rights.
 
  The Series A Preferred Stock is subject to a minimum and maximum dividend
rate of 7.00 percent and 15.00 percent, respectively. The dividend rate for the
quarterly dividend period ended June 30, 1995, is
 
                                       30
<PAGE>
 
7.00 percent. Shares of this series are redeemable, at the option of the
Company, at their stated value of $50 per share plus accrued and unpaid
dividends. Shares of this series are not convertible into other securities of
the Company.
 
  The Series B Preferred Stock is subject to a minimum and maximum dividend
rate of 6.00 percent and 12.00 percent, respectively. The dividend rate for the
quarterly period ended May 31, 1995, is 6.00 percent. Shares of this series are
redeemable, at the option of the Company, at their stated value of $100 per
share plus accrued and unpaid dividends. Shares of this series are not
convertible into other securities of the Company.
 
  The Series C Preferred Stock is subject to a minimum and maximum dividend
rate of 6.50 percent and 12.50 percent, respectively. The dividend rate for the
quarterly period ended May 31, 1995, is 6.50 percent. Shares of this series are
redeemable, at the option of the Company, at their stated value of $100 per
share plus accrued and unpaid dividends. Shares of this series are not
convertible into other securities of the Company.
 
  The Series E Preferred Stock is represented by depositary shares with each
depositary share representing a one-twenty-fifth interest in a share of Series
E Preferred Stock. The Series E Preferred Stock has an annual dividend rate
equal to $52.8125 ($2.1125 per depositary share), or 8.45 percent, which was
fixed at the date of issue. Shares of this series are redeemable, at the option
of the Company, at any time on or after November 16, 1997 at a redemption price
of $625 per share ($25 per depositary share). Shares of this series are not
convertible into other securities of the Company.
 
  The Series B Convertible Preferred Stock is represented by depositary shares
with each depositary share representing a one-hundredth interest in a share of
Series B Convertible Preferred Stock. The Series B Convertible Preferred Stock
has an annual dividend rate equal to $287.50 ($2.875 per depositary share), or
5 3/4 percent, which was fixed at the date of issue. Shares of the Company's
Series B Convertible Preferred Stock may be converted into shares of the
Company's Common Stock at a conversion price of $53 5/8 per share of Common
Stock (equivalent to a conversion rate of .9324 share of Common Stock for each
depositary share) at the option of the stockholder at any time. Resultant
fractional interests are paid in cash. The conversion rate is subject to
adjustment for certain stock dividends, subdivisions, splits and combinations,
certain distributions of assets and debt to holders of Common Stock, certain
reclassifications of Common Stock into other securities and certain
distributions of rights or warrants to purchase Common Stock at a price per
share less than the Common Stock's then market value. Shares of this series are
redeemable, at the option of the Company, on or after April 1, 1997, through
March 30, 2003, at an original redemption price of $5,172.50 ($51.7250 per
depositary share), declining over such period to $5,028.75 ($50.2875 per
depositary share), and thereafter at their stated value of $5,000 per share
($50.00 per depositary share) plus accrued and unpaid dividends.
 
  The shares of the outstanding Existing Preferred Stock (or with respect to
the Series E Preferred Stock and the Series B Convertible Preferred Stock, the
outstanding depositary shares representing such stock), are listed on the New
York Stock Exchange. First Chicago Trust Company of New York serves as transfer
agent, registrar and dividend disbursing agent for shares of the Existing
Preferred Stock and the depositary shares representing such stock. The First
National Bank of Chicago also serves as depositary for the shares of Existing
Preferred Stock represented by depositary shares.
 
                    DESCRIPTION OF PREFERRED STOCK WARRANTS

Stock. Preferred Stock Warrants may be issued independently or together with
other Securities offered by any Prospectus Supplement and may be attached to or

desirable and which will not materially and adversely affect the interests of
the owners.
 
  The Company and the Common Stock Warrant Agent also may modify or amend the
Common Stock Warrant Agreement and the terms of the Common Stock Warrants, with
the consent of the holders of not less than a majority in number of the then
outstanding unexercised Common Stock Warrants affected, provided that no such
modification or amendment that shortens the period of time during which the
Common Stock Warrants may be exercised, increases the exercise price of such
Common Stock Warrants or otherwise materially and adversely affects the
exercise rights of the holders of the Common Stock Warrants or reduces the
number of outstanding Common Stock Warrants the consent of whose holders is
required for modification or amendment of the Common Stock Warrant Agreement or
the terms of the Common Stock Warrants may be made without the consent of the
holders affected thereby.
 
COMMON STOCK WARRANT ADJUSTMENTS
 
  Unless otherwise indicated in the applicable Prospectus Supplement, the
exercise price of, and the number of shares of Common Stock covered by a Common
Stock Warrant, will be subject to adjustment in certain events, including: (i)
dividends (and other distributions) payable in the Common Stock on any class of
capital stock of the Company; (ii) subdivision, combinations and
reclassifications of Common Stock; (iii) the issuance to all holders of Common
Stock of certain rights or warrants entitling them to subscribe for or purchase
Common Stock, at less than the current market price (as defined in the Common
Stock Warrant Agreement for such series of Common Stock Warrants); and (iv) the
distribution to all holders of Common Stock of evidences of indebtedness or
assets of the Company (including securities, but excluding those dividends and
distributions referred to above and dividends and distributions paid in cash
out of surplus or retained earnings of the Company) or rights or warrants
(excluding those referred to above) of the Company, subject to the limitation
that all adjustments by reason of any of the foregoing need not be made until
they result in a cumulative change in the exercise price of at least 1%.
 
  In the event that the Company shall distribute or shall have distributed any
rights or warrants to acquire capital stock pursuant to clause (iv) of the
preceding paragraph ("Capital Stock Rights"), pursuant to which separate
certificates representing such Capital Stock Rights are distributed subsequent
to the initial distribution of such Capital Stock Rights (whether or not such
distribution shall have occurred prior to the date of the issuance of a series
of Common Stock Warrants), the subsequent distribution shall be deemed to be
the distribution of such Capital Stock Rights; provided, however, that the
Company may, in lieu of making any adjustment in the exercise price of, and the
number of shares of Common Stock covered by, a Common Stock Warrant upon a
distribution of separate certificates representing such Capital Stock Rights,
make proper provision so that each holder of such a Common Stock Warrant who
exercises such Common Stock Warrant (or any portion thereof) (a) on or before
the record date for such distribution of separate certificates shall be
entitled to receive upon such exercise shares of Common Stock issued with
Capital Stock Rights and (b) after such record date and prior to the
expiration, redemption or termination of such Capital Stock Rights shall be
entitled to receive upon such exercise, in addition to the shares of Common
Stock issuable upon such exercise, the same number of such Capital Stock Rights
as would a holder of the number of shares of Common Stock that such Common
Stock Warrant so exercised would have entitled the holder thereof to acquire in
accordance with the terms and provisions applicable to the Capital Stock Rights
if such Common Stock Warrant were exercised immediately prior to the record
date for such distribution. Common Stock owned by
 
                                       35
<PAGE>
 
or held for the account of the Company or any majority owned subsidiary shall
not be deemed outstanding for the purpose of any adjustment.
 
  In the event the Company shall effect any capital reorganization or
reclassification of its shares or shall consolidate, merge or engage in a
statutory share exchange with or into any other corporation (other than a
consolidation, merger or share exchange into which the Company is the surviving
corporation) or shall sell or transfer substantially all its assets to any
other corporation for a consideration consisting in whole or in part of equity
securities of such other corporation, the holders of the Common Stock Warrants
then outstanding will be entitled thereafter to exercise such Common Stock
Warrants to acquire the kind and amount of stock and other securities, cash or
property which they would have received in connection with such transaction had
such Common Stock Warrants been exercised immediately prior to such
transaction.
 
MERGER, CONSOLIDATION, SALE OR OTHER DISPOSITIONS
 
  If at any time there shall be a merger, consolidation, sale, transfer,
conveyance or other disposition of substantially all of the assets of the
Company, then the successor or assuming corporation shall succeed to and be
substituted for the Company in, and the Company will be relieved of any further
obligation under, the Common Stock Warrant Agreement or the Common Stock
Warrants.
 
                   DESCRIPTION OF THE COMPANY'S COMMON STOCK
 
GENERAL
 
  The Company is authorized to issue 150,000,000 shares of Common Stock. As of
December 31, 1994, there were outstanding 89,859,798 shares of the Company's
Common Stock.
 
  Holders of the Company's Common Stock are entitled to receive dividends when,
as and if declared by the Board of Directors out of any funds legally available
therefor, and are entitled upon liquidation, after claims of creditors and
preferences of the Company's preferred stock and any other series of preferred
stock hereafter authorized, to receive pro rata the net assets of the Company.
 
  The holders of the Common Stock are entitled to one vote for each share held
and are vested with all of the voting power except as the Board of Directors of
the Company has provided with respect to the outstanding shares of the
Company's preferred stock or may provide, in the future, with respect to any
other series of preferred stock which it may hereafter authorize. Directors of
the Company are elected for a one-year term expiring upon the annual meeting of
stockholders of the Company. The shares of the Company's Common Stock do not
have cumulative voting rights.
 
  The holders of the Company's Common Stock do not have any preemptive rights
to subscribe for additional shares of capital stock of the Company. The holders
of Common Stock have no conversion rights, the Common Stock is not subject to
redemption by either the Company or a stockholder, and there is no restriction
on the purchase by the Company of shares of Common Stock except for certain
regulatory limits.
 
  The Company's Common Stock is listed on the New York, Chicago, Pacific and
London Stock Exchanges. First Chicago Trust Company of New York is the transfer
agent, registrar and dividend disbursing agent for the Common Stock.
 
PREFERRED SHARE PURCHASE RIGHTS
 
  On November 18, 1988, the Board of Directors declared a dividend to holders
of Common Stock of record on December 2, 1988 (the "Record Date") of one
preferred share purchase right (a "Right") for each outstanding share of Common
Stock for, and to be attached to, each share of Common Stock outstanding on the
Record Date. Each Right entitles the registered holder to purchase from the
Company one one-hundreth
 
                                       36
<PAGE>
 
of a share of Series A Junior Participating Voting Preferred Stock, without par
value (the "Junior Preferred Shares"), of the Company, at a price of $130 per
one one-hundreth of a Junior Preferred Share, subject to certain adjustments.
As long as the Rights are attached to shares of Common Stock as provided in the
Rights Agreement referred to below, one additional Right shall be issued with
each share of Common Stock issued after December 2, 1988.
 
  The Rights will expire on December 2, 1998, unless the expiration date is
extended or the Rights are redeemed earlier and will not be exercisable or
transferable separately from the shares of Common Stock until the "Distribution
Date" which will occur on the earlier of (i) 10 days following a public
announcement that a person or group of affiliated or associated persons (an
"Acquiring Person") have acquired beneficial ownership of 20% or more of the
outstanding Common Stock or (ii) 10 business days (or such later date as may be
determined by action of the Board of Directors prior to such time as any person
becomes an Acquiring Person) following the commencement of, or announcement of
an intention to make, a tender offer or exchange offer the consummation of
which would result in the beneficial ownership by a person or group of 20% or
more of the outstanding Common Stock.
 
  In the event the Company is acquired in a merger or other business
combination transaction or 50% or more of its consolidated assets are sold,
each holder of a Right will have the right to receive, upon payment of the
Right's then current exercise price, common stock of the acquiring company
which has a market value of two times the exercise price of the Right. In the
event that any person becomes an Acquiring Person, each holder of a Right,
other than Rights beneficially owned by the Acquiring Person (which will
thereafter be void), will thereafter have the right to receive upon exercise
that number of shares of Common Stock (or under certain circumstances, Common
Stock-equivalent Junior Preferred Shares) having a market value of two times
the exercise price of the Rights.
 
  At any time after the acquisition by a person or group of affiliated or
associated persons of beneficial ownership of 20% or more of the outstanding
Common Stock and prior to the acquisition by such person or group of 50% or
more of the outstanding Common Stock, the Board of Directors may exchange the
Rights (other than Rights owned by such person or group which have become
void), in whole or in part, at an exchange ratio of one share of Common Stock
per Right, appropriately adjusted to reflect any stock split, stock dividend or
similar transaction (or under certain circumstances, Common Stock-equivalent
Junior Preferred Shares).
 
  At any time prior to the acquisition by a person or group of affiliated or
associated persons of beneficial ownership of 20% or more of the outstanding
Common Stock, the Board of Directors may redeem the Rights in whole, but not in
part, at a price of $.01 per Right, appropriately adjusted to reflect any stock
split, stock dividend or similar transaction (the "Redemption Price"). The
redemption of the Rights may be made effective at such time, on such basis and
with such conditions as the Board of Directors in its sole discretion may
establish.
 
  The purchase price payable, and the number of Junior Preferred Shares or
other securities or property issuable, upon exercise of the Rights are subject
to adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Junior
Preferred Shares, (ii) upon the grant to holders of the Junior Preferred Shares
of certain rights or warrants to subscribe for or purchase Junior Preferred
Shares at a price, or securities convertible into Junior Preferred Shares with
a conversion price, less than the current market price of the Junior Preferred
Shares or (iii) upon the distribution to holders of the Junior Preferred Shares
of evidences of indebtedness or assets (excluding regular periodic cash
dividends paid out of earnings or retained earnings or dividends payable in
Junior Preferred Shares) or of subscription rights or warrants (other than
those referred to above).
 
  The number of outstanding Rights and the number of one-hundreths of a Junior
Preferred Share issuable upon exercise of each Right are also subject to
adjustment in the event of a stock split of the Common Stock
 
                                       37
<PAGE>
 
or a stock dividend on the Common Stock payable in Common Stock or
subdivisions, consolidations or combinations of the Common Stock occurring, in
any such case, prior to the Distribution Date.
 
  The terms of the Rights may be amended by the Board of Directors without the
consent of the holders of the Rights, including an amendment to lower the
threshold for exercisability of the Rights from 20% to not less than the
greater of (i) any percentage greater than the largest percentage of the
outstanding Common Stock then known to the Company to be beneficially owned by
any person or group of affiliated or associated persons and (ii) 10%, except
that from and after such time as any person becomes an Acquiring Person no such
amendment may adversely affect the interests of the holders of the Rights.
 
  The Rights have certain anti-takeover effects. The Rights will cause
substantial dilution to a person or group that attempts to acquire the Company
on terms not approved by the Board of Directors. The Rights should not
interfere with any merger or other business combination approved by the Board
of Directors since the Rights may be redeemed by the Company at the Redemption
Price prior to the time that a person or group has acquired beneficial
ownership of 20% or more of the Common Stock.
 
  The foregoing description of the Rights and the Junior Preferred Shares does
not purport to be complete and is qualified in its entirety by reference to the
Rights Agreement, as amended, which is an exhibit to the Registration Statement
of which this Prospectus forms a part, and the Certificate of Designation,
Preferences and Rights for the Junior Preferred Shares.
 
                              PLAN OF DISTRIBUTION
 
  The distribution of the 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 Securities offered
therein.
 
  The Company may sell 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 Securities to which such Prospectus
Supplement relates, including the name or names of any underwriters or agents
with whom the Company has entered into arrangements with respect to the sale of
such Securities, the public offering or purchase price of such Securities and
the net proceeds to the Company 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
Securities will be listed. Dealer trading may take place in certain of the
Securities, including 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 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 Securities will be subject to certain conditions precedent and
each of the underwriters with respect to a sale of Securities will be obligated
to purchase all of its 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.
 
  Securities may be offered and sold by the Company through agents designated
by the Company from time to time. Any agent involved in the offer and sale of
any Securities will be named, and any commissions payable by the Company to
such agent will be set forth, in the Prospectus Supplement relating to such
 
                                       38
<PAGE>
 
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 Securities may be solicited directly by the Company and
sales thereof may be made by the Company 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.
 
  The Company may also issue contracts under which the counterparty may be
required to purchase Debt Securities, Preferred Stock, Depositary Shares or
Common Stock. Such contracts would be issued with Debt Securities, Preferred
Stock or Depositary Shares and/or Warrants in amounts, at prices and on terms
to be set in a Prospectus Supplement.
 
  The anticipated place and time of delivery of Securities will be set forth in
the applicable Prospectus Supplement.
 
  If so indicated in the applicable Prospectus Supplement, the Company will
authorize underwriters or agents to solicit offers by certain institutions to
purchase Securities from the Company 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
the Company. 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 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 Securities are
also being sold to underwriters acting as principals for their own account, the
underwriters shall have purchased such Securities not sold for delayed
delivery. The underwriters and such other persons will not have any
responsibility in respect of the validity or performance of such contracts.
 
  Any underwriter or agent participating in the distribution of the Securities
may be deemed to be an underwriter, as that term is defined in the Securities
Act, of the Securities so offered and sold and any discounts or commissions
received by them from the Company and any profit realized by them on the sale
or resale of the Securities may be deemed to be underwriting discounts and
commissions under the Securities Act.
 
  Underwriters and agents may be entitled, under agreements entered into with
the Company, to indemnification by the Company against certain civil
liabilities, including liabilities under the Securities Act, or to contribution
with respect to payments which such underwriters or agents may be required to
make in respect thereof. Certain of any such underwriters and agents, including
their associates, may be customers of, engage in transactions with and perform
services for, the Company and its subsidiaries in the ordinary course of
business. An affiliate of the Company may from time to time act as an agent or
underwriter in connection with the sale of Securities to the extent permitted
by applicable law. The participation of such affiliate in the offer and sale of
the Securities will comply with Schedule E of the By-laws of the National
Association of Securities Dealers, Inc. regarding the offer and sale of
securities of an affiliate.
 
  This Prospectus and related Prospectus Supplements may be used by an
affiliate of the Company in connection with offers and sales related to
secondary market transactions in Securities. Such affiliate, to the extent
permitted by law, may act as principal or agent in such transactions. Such
sales will be made at prices related to prevailing market prices at the time of
sale.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Section 145 of the General Corporation Law of Delaware contains detailed
provisions on indemnification of directors and officers of a Delaware
corporation against expenses, judgments, fines and amounts paid in settlement,
actually and reasonably incurred in connection with litigation.
 
  Article Ninth of the Restated Certificate of Incorporation, as amended, of
the Registrant provides for indemnification of directors and officers to the
full extent permitted or allowed by the laws of the State of Delaware, as such
laws exist or may hereafter be amended (but, in the case of any such amendment,
only to the extent that such amendment permits the Registrant to provide
broader indemnification rights than said law permitted the Registrant to
provide prior to such amendment) whether or not specifically required,
permitted or allowed by said Section 145. The Registrant also insures its
officers and directors to the full extent permitted by said Section 145.

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
  (other than as provided in Item 512 of Regulation S-K); (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 (other
  than as provided in Item 512 of Regulation S-K); and (iii) to include any
  material information with respect to the plan of distribution not
  previously disclosed in the Registration Statement or any material change
  to such information in the Registration Statement.
 
  Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
registration statement is on Form S-3, and the information required to be
included in a post-effective amendment by those paragraphs 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
in the registration statement.
 
    (2) That, for the purpose of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof.
 
    (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.
 
    (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
 
                                      II-3
<PAGE>
 
  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) That, insofar as indemnification for liabilities arising under the
  Securities Act of 1933 may be permitted to directors, officers and
  controlling persons of the registrant pursuant to the foregoing provisions,
  or otherwise, the registrant has been advised that in the opinion of the
  Securities and Exchange Commission such indemnification is against public
  policy as expressed in the Act and is, therefore, unenforceable. In the
  event that a claim for indemnification against such liabilities (other than
  the payment by the registrant of expenses incurred or paid by a director,
  officer or controlling person of the registrant in the successful defense
  of any action, suit or proceeding) is asserted by such director, officer or
  controlling person in connection with the securities being registered, the
  registrant will, unless in the opinion of its counsel the matter has been
  settled by controlling precedent, submit to a court of appropriate
  jurisdiction the question whether such indemnification by it is against
  public policy as expressed in the Act and will be governed by the final
  adjudication of such issue.

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

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
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

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,

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

its proxy or proxies to the beneficial owners of interests in any such Global
Security through such Depositary's standing instructions and customary
practices.

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
 
                                       9

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 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.

"incorporated provision") included in this Indenture by operation of Sections
310 to 318, inclusive, of the TIA, such imposed duties or incorporated

hereunder and the Holders, any benefit or any legal or equitable right, remedy
or claim under this Indenture.
 
SECTION 1.13. Legal Holidays.
 
  In any case where any Interest Payment 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 Date 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, as the case may be.

<PAGE>
 
  All Securities of any one series and the coupons appertaining to Bearer
Securities of such series, if any, shall be substantially identical except, in
the case of Registered Securities, as to denomination and except as may
otherwise be provided in or pursuant to such Board Resolution and set forth, or
determined in the manner provided, in such Officers' Certificate or in any such
indenture supplemental hereto.
 
  Securities of any particular series may be issued at various times, with
different dates on which the principal or any instalment of principal is
payable, with different rates of interest, if any, or different methods by
which rates of interest may be determined, with different dates on which such
interest may be payable and with different Redemption Dates or Repayment Dates
and may be denominated in different currencies or payable in different
currencies.
 
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, its Chief Financial
Officer or one of its Executive 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, its Chief Financial Officer, one of its Executive Vice
Presidents or the Treasurer.
 
  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
 
                                       15
<PAGE>
 
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, at the time of its designation and at all times while it
serves as Depositary, be a clearing agency registered under the Securities
Exchange Act of 1934, as amended, 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, 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 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.
 
                                       16
<PAGE>
 
  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
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 cancelled. 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 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
 
                                       17
<PAGE>
 
  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
  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 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
 
                                       18
<PAGE>
 
  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
  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.
 
                                       19
<PAGE>
 
  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
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.
 
                                       20
<PAGE>
 
  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 temporary 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 cancelled 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
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.
 
                                       21
<PAGE>
 
  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.
 
SECTION 3.06. Mutilated, Destroyed, Lost and Stolen Securities.
 
  If (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 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 destroyed, lost or stolen coupon
appertains (with all appurtenant coupons not 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 lieu of any destroyed, lost or stolen Security, or in
exchange for a Security with a destroyed, lost or stolen coupon, shall
constitute an original additional contractual obligation of the Company,
whether or not the destroyed, lost or stolen Security and its coupons, if any,
or the destroyed, lost or stolen coupon shall be at any time enforceable by
anyone, and shall be entitled to all the benefits of this Indenture
 
                                       22
<PAGE>
 
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
 
                                       23
<PAGE>
 
  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.
 
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.
 
SECTION 3.09. Cancellation.
 
  Unless otherwise provided with respect to a series of Securities, all
Securities and coupons surrendered for payment, 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
 
                                       24
<PAGE>
 
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 3.10. Computation of Interest.
 
  Interest on the Securities of each series shall be computed as shall be
specified as contemplated by Section 3.01.
 
SECTION 3.11. Forms of Certification.
 
  Unless otherwise provided pursuant to Section 3.01:
 
    (i) Whenever any provision of this Indenture or the forms of Securities
  contemplate that certification be given by a Person entitled to receive a
  Bearer Security, such certification shall be provided substantially in the
  form of Exhibit A hereto, with only such changes as shall be approved by
  the Company.
 
    (ii) Whenever any provision of this Indenture or the forms of Securities
  contemplate that certification be given by Euroclear and CEDEL S.A. in
  connection with the exchange of a portion of a temporary Global Security,
  such certification shall be provided substantially in the form of Exhibit B
  hereto, with only such changes as shall be approved by the Company.
 
    (iii) Whenever any provision of the Indenture or the forms of Securities
  contemplate that certification be given by Euroclear and CEDEL S.A. in
  connection with payment of interest with respect to a temporary Global
  Security prior to the related Global Exchange Date, such certification
  shall be provided substantially in the form of Exhibit C hereto, with only
  such changes as shall be approved by the Company.
 
    (iv) Whenever any provision of the Indenture or the forms of Securities
  contemplate that certification be given by a beneficial owner of a portion
  of a temporary Global Security in connection with payment of interest with
  respect to a temporary Global Security prior to the related Global Exchange
  Date, such certification shall be provided substantially in the form of
  Exhibit D hereto, with only such changes as shall be approved by the
  Company.
 
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 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

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.
 
                                  ARTICLE FOUR
 
                            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 or condition.
 
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 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.
 
                                       26
<PAGE>
 
  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 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 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 instalments 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. Instalments 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.
 
                                       27
<PAGE>
 
  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 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.
 
                                  ARTICLE FIVE
 
                                   COVENANTS
 
SECTION 5.01. Payment of Principal, Premium and Interest.
 
  The Company covenants and agrees for the benefit of each series of Securities
that it will duly and punctually pay the principal of, 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 instalments 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
 
                                       28
<PAGE>
 
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 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 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
 
                                       29
<PAGE>
 
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
Bank at its principal office as its Paying Agent in the City of Chicago with
respect to all series of Securities having a Place of Payment in the City of
Chicago.
 
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 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
 
                                       30
<PAGE>
 
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
reasonable expense incurred without negligence or bad faith on their part
arising out of or in connection with actions taken or omitted by any of them in
reliance on any Officers' Certificate furnished pursuant to this Section.
 
SECTION 5.05. Statement as to Compliance.
 
  The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year of the 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
 
    (i) a review of the activities of the Company during such year and of
  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, an Event of Default, or if such an event has occurred
  and is continuing, specifying such event known to him and the nature and
  status thereof.
 
                                       31
<PAGE>
 
  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 prevent (i) 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, or (ii) 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.
 
                                  ARTICLE SIX
 
               HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY
 
SECTION 6.01. Company to Furnish Trustee Names and Addresses of Holders.
 
  The Company will furnish or cause to be furnished to the Trustee (i)
semiannually, not more than 10 days after each February 1 and August 1, a list,
in such form as the Trustee may reasonably require, containing all the
information in the possession or control of the Company, any of its Paying
Agents (other than the Trustee) or the Security Registrar, if other than the
Trustee, as to the names and addresses of the Holders of Securities as of such
February 1 and August 1, and (ii) at such other times as the Trustee may
request in writing, within 30 days after receipt by the Company of any such
request, a list of similar form and content as of a date not more than 15 days
prior to the time such list is requested to be furnished; provided, however,
that if and so long as the Trustee is the Security Registrar for Securities of
a series, no such list need be furnished with respect to such series of
Securities.
 
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 Holders the form of proxy or other communication, if
  any, specified in such application.
 
                                       32
<PAGE>
 
  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).
 
SECTION 6.03. Reports by Trustee.
 
  (i) Within 60 days after May 1 of each year commencing with the year 1996,
the Trustee shall mail to each Holder reports concerning the Trustee and its
action under the Indenture as may be required pursuant to the Trust Indenture
Act if and to the extent and in the manner provided pursuant thereto.
 
  (ii) Reports pursuant to this Section shall be transmitted by mail (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 Security of
any series whose name and address appear in the information preserved at the
time by the Trustee in accordance with Section 6.02(i).
 
  (iii) A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Trustee with each securities exchange upon which any
Securities are listed, and also with the Commission. The Company will notify
the Trustee when any Securities are listed on any securities exchange.
 
SECTION 6.04. Reports by Company.
 
  The Company will:
 
    (i) file with the Trustee, within 15 days after the Company is required
  to file the same with the Commission, copies of the annual reports and of
  the information, documents and other reports (or copies of such portions of
  any of the foregoing as the Commission may from time to
  time by rules and regulations prescribe) which the Company may be required

SECTION 7.01. Events of Default.
 
  "Event of Default", with respect to 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 administrative or
governmental body), unless it is either inapplicable to a particular series or
it is specifically deleted or modified in the supplemental indenture or Board
Resolution under which such series of Securities is issued or in the form of
Security for such series:
 
    (i) default in the payment of any interest upon any Security of that
  series when it becomes due and payable, and continuance of such default for
  a period of 30 days; or
 
    (ii) default in the payment of the principal of (or premium, if any, on)
  any Security of that series at its Maturity; or
 
    (iii) default in the performance, or breach, of any covenant or warranty
  of the Company in this Indenture (other than a covenant or warranty a
  default in whose performance or whose breach is elsewhere in this Section
  specifically dealt with or which has expressly been included in this
  Indenture solely for the benefit of series of Securities other than that
  series), and continuance of such default or breach for a period of 60 days
  after there has been given, by registered or certified mail, to the Company
  by the Trustee or to the Company and the Trustee by the Holders of at least
  25% in principal amount of the Outstanding Securities of that series a
  written notice specifying such default or breach and requiring it to be
  remedied and stating that such notice is a "Notice of Default" hereunder;
  or
 
    (iv) if an event of default as defined in any mortgage, indenture or
  instrument under which there may be issued, or by which there may be
  secured or evidenced, any indebtedness for money borrowed of the Company,
  whether such indebtedness now exists or shall hereafter be created, shall
  happen and shall result in any such indebtedness in principal amount in
  excess of $1,000,000 becoming or being duly declared due and payable prior
  to the date on which it would otherwise become due and payable, and such
  acceleration shall not be rescinded or annulled, or such indebtedness shall
  not have been discharged, within a period of 30 days after there has been
  given, by registered or certified mail, to the Company by the Trustee or to
  the Company and the
 
                                       34

  Trustee by the Holders of at least 25% in principal amount of the
  Outstanding Securities of that series a written notice specifying such
  event of default and requiring the Company to cause such acceleration to be
  rescinded or annulled or to cause such indebtedness to be discharged and
  stating that such notice is a "Notice of Default" hereunder; provided,
  however, that, if such default under such mortgage, indenture or instrument
  shall be cured by the Company, or be waived by the holders of such
  indebtedness, in each case as may be permitted by such instrument, then the
  Event of Default hereunder by reason of such default shall be likewise
  deemed to have been cured or waived; and provided, further, that, subject
  to Section 8.01, the Trustee shall not be charged with knowledge of any
  such default unless either (a) a Responsible Officer of the Trustee
  assigned to its corporate trust department shall have actual knowledge of
  such default, or (b) written notice of such default shall have been given
  to the Trustee by the Company, by the trustee then acting under any
  indenture or other instrument under which such default shall have occurred
  or by the Holders of at least 25% in aggregate principal amount of the
  Securities of that series then Outstanding; or
 
    (v) the entry of a decree or order by a court having jurisdiction in the
  premises granting relief in respect of the Company or the Bank in an
  involuntary case under the Federal Bankruptcy Code, adjudging the Company
  or the Bank a bankrupt or insolvent, or approving as properly filed a
  petition seeking reorganization, arrangement, adjustment or composition of
  or in respect of the Company or the Bank under the Federal Bankruptcy Code
  or any other applicable Federal or State law, or appointing a receiver,
  liquidator, custodian, assignee, trustee, sequestrator (or other similar
  official) of the Company or the Bank, or of any substantial part of their
  respective properties, or ordering the winding up or liquidation of their
  respective affairs, and the continuance of any such decree or order
  unstayed and in effect for a period of 60 consecutive days; or
 
    (vi) the institution by the Company or the Bank of proceedings to be
  adjudicated a bankrupt or insolvent, or the consent by the Company or the
  Bank to the institution of bankruptcy or insolvency proceedings against it,
  or the filing by the Company or the Bank of a petition or answer or consent
  seeking reorganization or relief under the Federal Bankruptcy Code or any
  other applicable Federal or State law, or the consent by the Company or the
  Bank to the filing of any such petition or to the appointment of a
  receiver, liquidator, custodian, assignee, trustee, sequestrator (or other
  similar official) of the Company or the Bank, or of any substantial part of
  their respective properties, or the making by the Company or the Bank of an
  assignment for the benefit of creditors, or the admission by the Company or
  the Bank in writing of its inability to pay its debts generally as they
  become due, or the taking of corporate action by the Company or the Bank in
  furtherance of any such action; or
 
    (vii) any other Event of Default provided with respect to Securities of
  that series.
 
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
Trustee, may rescind and annul such declaration and its consequences if
 
                                       35
<PAGE>
 
    (i) the Company has paid or deposited with the Trustee a sum sufficient
  to pay
 
      (a) all overdue instalments of interest on all Securities of such
    series,
 
      (b) the principal of and premium, if any, on any Securities of such
    series which have become due otherwise than by such declaration of
    acceleration and interest thereon at the rate or rates prescribed
    therefor by the terms of the Securities of such series,
 
      (c) to the extent that payment of such interest is lawful, interest
    upon overdue instalments of interest at the rate or rates prescribed
    therefor by the terms of the Securities of such series, and
 
      (d) all sums paid or advanced by the Trustee hereunder and the
    reasonable compensation, expenses, disbursements and advances of the
    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 non-payment of the principal of Securities of that series
  which have become due solely by such declaration of acceleration, have been
  cured or waived as provided in Section 7.13.
 
No such recission 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 instalments 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 adjudged or decreed to be payable in the
manner provided by law out of the property of the Company or any other obligor
upon such Securities, wherever situated.
 
  If an Event of Default with respect to 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,
 
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.
 
SECTION 7.05. Trustee May Enforce Claims Without Possession of Securities.
 
  All rights of action and claims under this Indenture or under the 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.
 
SECTION 7.06. Application of Money Collected.
 
  Any money collected by the Trustee with respect to a series of Securities
pursuant to this Article shall be applied in the following order, at the date
or dates fixed by the Trustee, and, in case of the distribution of such money
on account of principal, premium, if any, or interest, upon presentation of the
Securities of such series or coupons appertaining thereto, if any, or both, as
the case may be, and the notation thereon of the payment if only partially paid
and upon surrender thereof if fully paid:
 
    FIRST: To the payment of all amounts due the Trustee under Section 8.07;
 
    SECOND: To the payment of the amounts then due and unpaid upon the
  Securities of such series and coupons for principal, premium, if any, and
  interest, in respect of which or for the
 
                                       37
<PAGE>
 
  benefit of which such money has been collected, ratably, without preference
  or priority of any kind, according to the amounts due and payable on
  Securities of such series and coupons, if any, for principal, premium, if
  any, and interest, respectively. The Holders of each series of Securities
  denominated in ECU, any other composite currency or a Foreign Currency and
  any matured coupons relating thereto shall be entitled to receive a ratable
  portion of the amount determined by the Exchange Rate Agent by converting
  the principal amount Outstanding of such series of Securities and matured
  but unpaid 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
 
    THIRD: The balance, if any, to the Person or Persons entitled thereto.
 
SECTION 7.07. Limitation on Suits.
 
  No Holder of any Security of any series or any related coupons shall have any
right to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless
 
    (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 25% in principal amount of the
  Outstanding Securities of such series shall have made written request to
  the Trustee to institute proceedings in respect of such Event of Default in
  its own name as Trustee hereunder;
 
    (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
 
    (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
 
                                       38
<PAGE>
 
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, destroyed or stolen Securities or coupons in the last
paragraph of Section 3.06, no right or remedy herein conferred upon or reserved
to the Trustee or to the Holders is intended to be exclusive of any other right
or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent
the concurrent assertion or employment of any other appropriate right or
remedy.
 
SECTION 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 acquiesence 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 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
 
    (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.

<PAGE>
 
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 extention 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.

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.
 
  (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;
 
                                       40
<PAGE>
 
    (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 principal of, premium, if any, or
interest on any Security of such series, or any related coupons or in the
payment of any sinking fund instalment with respect to Securities of such
series the Trustee shall be protected in withholding such notice if and so long
as the board of directors, the executive committee or a trust committee of
directors 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 60 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 provided in Section 8.01:
 
    (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

    (iv) the Trustee may consult with counsel and the advice of such counsel
  or any Opinion of Counsel shall be full and complete authorization and
  protection in respect of any action taken, suffered or omitted by it
  hereunder in good faith and in reliance thereon;
 
    (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
  have offered to the Trustee reasonable security or indemnity against the
  costs, expenses and liabilities which might be incurred by it in compliance
  with such request or direction;
 
    (vi) the Trustee shall not be bound to make any investigation into the

  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
  defined in Section 8.02) or Event of Default unless either (1) a
  Responsible Officer of the Trustee shall have actual knowledge of such
  default or Event of Default or (2) written notice of such default or Event
  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
  omitted by it in good faith and reasonably believed by it to be authorized
  or within the discretion or rights or powers conferred upon it by this
  Indenture.
 
SECTION 8.04. Not Responsible for Recitals or Issuance of Securities.
 
  The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the
Company, 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);
 
                                       42
<PAGE>
 
    (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.
 
  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, 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 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
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.
 
                                       43

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,
 
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.
 
                                       44
<PAGE>
 
  (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, subject nevertheless to its lien, if any, provided for
in Section 8.07.
 
  (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.
 
                                       45
<PAGE>
 
  (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 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
 
                                       46
<PAGE>
 
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.

    (iii) to add to the covenants of the Company, for the benefit of the
  Holders of Securities of all or any series of Securities or coupons (and if
  such covenants are to be for the benefit of less than all series of
  Securities or coupons, stating that such covenants are expressly being
  included solely for the benefit of such series), or to surrender any right
  or power herein conferred upon the Company; or
 
    (iv) to cure any ambiguity, to correct or supplement any provision herein
  which may be inconsistent with any other provision herein, or to make any
  other provisions with respect to matters or questions arising under the
  Indenture, provided that such action shall not adversely affect the
  interests of the Holders of Securities of any series or any related coupons
  in any material respect; or
 
    (v) to add any additional Events of Default with respect to all or any
  series of the Securities (and, if such Event of Default is applicable to
  less than all series of Securities, specifying the series to which such
  Event of Default is applicable); or
 
    (vi) to add to, change or eliminate any of the provisions of this
  Indenture to provide that Bearer Securities may be registrable as to
  principal, to change or eliminate any restrictions on the payment of
  principal of (or premium, if any) or any interest on Bearer Securities, to
  permit Bearer Securities to be issued in exchange for Registered
  Securities, to permit Bearer Securities to be issued in exchange for Bearer
  Securities of other authorized denominations or to permit or facilitate the
  issuance of Securities in uncertificated form, provided any such action
  shall not adversely affect the interests of the Holders of Securities of
  any series or any related coupons in any material respect; or
 
    (vii) to add to, change or eliminate any of the provisions of this
  Indenture, provided that any such addition, change or elimination (a) shall
  become effective only when there is no Security Outstanding of any series
  created prior to the execution of such supplemental indenture which is
  adversely affected by such change in or elimination of such provision or
  (b) shall not apply to any Securities Outstanding; or
 
    (viii) to establish the form or terms of Securities of any series as
  permitted by Sections 2.01 and 3.01; or
 
    (ix) to add to or change any provisions of this Indenture to such extent
  as shall be necessary to permit or facilitate the issuance of Securities
  convertible into other securities; or
 
    (x) to evidence any changes to Section 8.09 as permitted by the terms
  thereof; or
 
    (xi) to add to or change or eliminate any provision of this Indenture as
  shall be necessary or desirable in accordance with any amendments to the
  Trust Indenture Act, provided such action shall not adversely affect the
  interest of Holders of Securities of any series or any appurtenant coupons
  in any material respect.
 
SECTION 9.02. Supplemental Indentures With Consent of Holders.
 
  With the consent of the Holders of not less than a majority in aggregate
principal amount of the Outstanding Securities of all series affected by such
supplemental indenture or indentures (acting as one class), by Act of said

by a Board Resolution, and the Trustee may enter into an indenture or
indentures supplemental hereto for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Indenture
or of modifying in any manner the rights of the Holders of Securities of each
such series and any related coupons under this Indenture; provided, however,
that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Security affected thereby;
 
    (i) change the Maturity of the principal of, or the Stated Maturity of
  any instalment of interest (or premium, if any) on, any Security, or reduce
  the principal amount thereof or any
 
                                       48

  premium thereon or the rate of interest thereon, or change the obligation
  of the Company to pay additional amounts pursuant to Section 5.04 (except

  that would be due and payable upon a declaration of acceleration of the
  Maturity thereof pursuant to Section 7.02, or change the method of
  calculating interest thereon or the coin or currency in which any Security
  (or premium, if any, thereon) or the interest thereon is payable, or reduce
  the minimum rate of interest thereon, or impair the right to institute suit
  for the enforcement of any such payment on or after the Stated Maturity
  thereof (or, in the case of redemption or repayment, on or after the

  of this Indenture cannot be modified or waived.
 
  A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included soley for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with respect to such
covenant or other provision, shall be deemed not to affect the rights under
this Indenture of the Holders of Securities of any other series.
 
  It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it
shall be sufficient if such Act shall approve the substance thereof.

  In executing, or accepting the additional trusts created by, any supplemental
indenture permitted by this Article or the modifications thereby of the trusts
created by this Indenture, the Trustee shall be entitled to receive, and

                                 SINKING FUNDS
 
SECTION 13.01. Applicability of Article.
 
  The provisions of this Article shall be applicable to any sinking fund for

contemplated by Section 3.01 for Securities of such series.
 
  The minimum amount of any sinking fund payment provided for by the terms of
Securities of any series is herein referred to as a "mandatory sinking fund
payment", and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment". If provided for by the terms of Securities of any series, the

either at the election of the Company pursuant to the terms of such Securities
or through
 
                                       52
<PAGE>
 
the application of permitted optional sinking fund payments pursuant to the
terms of such Securities, in each case in satisfaction of all or any part of
any sinking fund payment with respect to the Securities of such series required
to be made pursuant to the terms of such Securities as provided for by the
terms of such series; provided that such Securities have not been previously so
credited. Such Securities shall be received and credited for such purpose by
the Trustee at the Redemption Price specified in such Securities for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly.
 
SECTION 13.03. Redemption of Securities for Sinking Fund.
 
  Not less than 60 days prior to each sinking fund payment date for any series
of Securities, the Company will deliver to the Trustee and the Security
Registrar an Officers' Certificate specifying (i) the amount of the next
ensuing sinking fund payment for that series pursuant to the terms of that
series, (ii) the portion thereof, if any, which is to be satisfied by payment
of cash and the portion thereof, if any, which is to be satisfied by delivering
and crediting Securities of that series pursuant to Section 13.02, and (iii)
that none of such Securities has theretofore been so credited and stating the
basis for such credit, and will also deliver to the Trustee any Securities to
be so delivered. Not less than 30 days before each sinking fund payment date
the Security Registrar shall select the Securities to be redeemed upon such
sinking fund payment date in the manner specified in Section 4.03 and cause
notice of the redemption thereof to be given in the name of and at the expense
of the Company in the manner provided in Section 4.04. Such notice having been
duly given, the redemption of such Securities shall be made upon the terms and
in the manner stated in Sections 4.06 and 4.07.

                       REPAYMENT AT THE OPTION OF HOLDERS
 
SECTION 14.01. Applicability of Article.
 
  Securities of any series which are repayable at the option of the Holders
thereof before their Stated Maturity shall be repaid in accordance with their
terms and (except as otherwise specified pursuant to Section 3.01 for
Securities of such series) in accordance with this Article.
 
Section 14.02. Repayment of Securities.
 
  Each Security which is subject to repayment in whole or in part at the option
of the Holder thereof on a Repayment Date shall be repaid at the applicable
Repayment Price together with interest accrued to such Repayment Date as
specified pursuant to Section 3.01.
 
Section 14.03. Exercise of Option; Notice.
 
  Each Holder desiring to 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 together with written notice of exercise of such
option shall be made at an office or agency located outside the United States
except as otherwise provided 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.
 
                                       53
<PAGE>
 
  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
be payable only at an office or agency located outside the United States except
as otherwise provided in Section 5.02.
 
  The Company shall execute and the Trustee shall authenticate and deliver
without service charge to the Holder of any Registered Security so surrendered
a new Registered Security or Securities of the same series and tenor, of any
authorized denomination specified in the foregoing notice, in an aggregate
principal amount equal to any portion of the principal of the Registered
Security so surrendered which is not to be repaid.
 
  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 Securities (and
all appurtenant unmatured coupons and matured coupons in default) or any
combination thereof of the same series and tenor of any 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 paid; 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.
 
  For all purposes of this Indenture, unless the context otherwise 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 of the
principal of such Security which has been or is to be repaid.
 
Section 14.04. Election of Repayment by Remarketing Entities.

repayable at the option of the Holders thereof before their Stated Maturity, at
any time prior to any Repayment Date to designate one or more Remarketing
Entities to purchase, at a price equal to the Repayment Price, Securities of
such series from the Holders thereof who give notice and surrender their
Securities in accordance with Section 14.03.
 
Section 14.05. Securities Payable on the Repayment Date.
 
  Notice of exercise of the option of repayment having been given and the
Securities so to be repaid having been surrendered as aforesaid, such
Securities shall, unless 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
 
                                       54
<PAGE>
 
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 of such
principal amount.

or opinion need be furnished.
 
  Every certificate or opinion with respect to compliance with a condition or

    (i) a statement that each individual signing such certificate or opinion

  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

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
 
                                       8
<PAGE>
 
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 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
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.
 
  (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,
 
                                       10
<PAGE>
 
  (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 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.

"incorporated provision") included in this Indenture by operation of Sections
310 and 318, inclusive, of the TIA, such imposed duties or incorporated

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.
 
SECTION 1.13. Legal Holidays.
 
  In any case where any Interest Payment 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 Date 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

  any interest on Securities of the series may be determined with reference
  to an index, the method or methods by which such amounts shall be
  determined;
 
 
                                       15
<PAGE>
 
    (xviii) if other than the principal amount thereof, the portion of the
  principal amount of Securities of the series which shall be payable upon
  declaration of acceleration of the Maturity thereof pursuant to Section
  7.02;
 
    (xix) any addition to or change in the Events of Default or covenants of
  the Company pertaining to the Securities of the series; and
 
    (xx) any other terms of the series.
 
  All Securities of any one series and the coupons appertaining to Bearer
Securities of such series, if any, shall be substantially identical except, in
the case of Registered Securities, as to denomination and except as may
otherwise be provided in or pursuant to such Board Resolution and set forth, or
determined in the manner provided, in such Officers' Certificate or in any such
indenture supplemental hereto.
 
  Securities of any particular series may be issued at various times, with
different dates on which the principal or any instalment of principal is
payable, with different rates of interest, if any, or different methods by
which rates of interest may be determined, with different dates on which such
interest may be payable and with different Redemption Dates or Repayment Dates
and may be denominated in different currencies or payable in different
currencies.
 
  All Securities shall be subordinate and junior in right of payment to the
obligations of the Company to holders of Senior Indebtedness and creditors in
respect of General Obligations of the Company as provided in Article Fourteen.
 
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, its Chief Financial
Officer or one of its Executive 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, its Chief Financial Officer, one of its Executive Vice
Presidents or the Treasurer.
 
  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
 
                                       16
<PAGE>
 
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, at the time of its designation and at all times while it
serves as Depositary, be a clearing agency registered under the Securities
Exchange Act of 1934, as amended, 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,
  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.
 
  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.
 
                                       17
<PAGE>
 
  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 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 cancelled. 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 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
 
                                       18
<PAGE>
 
  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
  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 definitive
  Securities without
 
                                       19
<PAGE>
 
  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,
 
                                       20
<PAGE>
 
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
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
 
                                       21
<PAGE>
 
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 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 temporary 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 cancelled 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.
 
                                       22
<PAGE>
 
  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 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.
 
SECTION 3.06. Mutilated, Destroyed, Lost and Stolen Securities.
 
  If (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 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 destroyed, lost or stolen coupon
appertains (with all appurtenant coupons not 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.
 
 
                                       23

  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 lieu of any destroyed, lost or stolen Security, or in
exchange for a Security with a destroyed, lost or stolen coupon, shall
constitute an original additional contractual obligation of the Company,
whether or not the destroyed, lost or stolen Security and its coupons, if any,
or the destroyed, lost or stolen coupon shall be at any time enforceable by
anyone, and 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
 
                                       24
<PAGE>
 
  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.
 
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.
 
 
                                       25
<PAGE>
 
  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.
 
SECTION 3.09. Cancellation.
 
  Unless otherwise provided with respect to a series of Securities, all
Securities and coupons surrendered for payment, 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 3.10. Computation of Interest.
 
  Interest on the Securities of each series shall be computed as shall be
specified as contemplated by Section 3.01.
 
SECTION 3.11. Forms of Certification.
 
  Unless otherwise provided pursuant to Section 3.01:
 
    (i) Whenever any provision of this Indenture or the forms of Securities
  contemplate that certification be given by a Person entitled to receive a
  Bearer Security, such certification shall be provided substantially in the
  form of Exhibit A hereto, with only such changes as shall be approved by
  the Company.
 
    (ii) Whenever any provision of this Indenture or the forms of Securities
  contemplate that certification be given by Euroclear and CEDEL S.A. in
  connection with the exchange of a portion of a temporary Global Security,
  such certification shall be provided substantially in the form of Exhibit B
  hereto, with only such changes as shall be approved by the Company.
 
    (iii) Whenever any provision of the Indenture or the forms of Securities
  contemplate that certification be given by Euroclear and CEDEL S.A. in
  connection with payment of interest with respect to a temporary Global
  Security prior to the related Global Exchange Date, such certification
  shall be provided substantially in the form of Exhibit C hereto, with only
  such changes as shall be approved by the Company.
 
    (iv) Whenever any provision of the Indenture or the forms of Securities
  contemplate that certification be given by a beneficial owner of a portion
  of a temporary Global Security in connection with payment of interest with
  respect to a temporary Global Security prior to the related Global Exchange
  Date, such certification shall be provided substantially in the form of
  Exhibit D hereto, with only such changes as shall be approved by the
  Company.

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 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.
 
                                  ARTICLE FOUR
 
                            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 or condition.
 
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 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
 
                                       27
<PAGE>
 
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 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
 
                                       28
<PAGE>
 
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 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 instalments 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. Instalments 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 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
 
                                       29
<PAGE>
 
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.
 
                                  ARTICLE FIVE
 
                                   COVENANTS
 
SECTION 5.01. Payment of Principal, Premium and Interest.
 
  The Company covenants and agrees for the benefit of each series of Securities
that it will duly and punctually pay the principal of, 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 instalments 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 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,
 
                                       30
<PAGE>
 
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 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 Chase Manhattan Bank (National Association), 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 Bank at its principal office as
its Paying Agent in the City of Chicago with respect to all series of
Securities having a Place of Payment in the City of Chicago.
 
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
 
                                       31
<PAGE>
 
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
 
                                       32
<PAGE>
 
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.
 
SECTION 5.05. Statement as to Compliance.
 
  The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year of the 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
 
    (i) a review of the activities of the Company during such year and of
  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 prevent (i) 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, or (ii) 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.

               HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY
 
SECTION 6.01. Company to Furnish Trustee Names and Addresses of Holders.
 
  The Company will furnish or cause to be furnished to the Trustee (i)
semiannually, not more than 10 days after each February 1 and August 1, a list,
in such form as the Trustee may reasonably require, containing all the
information in the possession or control of the Company, any of its Paying
Agents (other than the Trustee) or the Security Registrar, if other than the
Trustee, as to the names and addresses of the Holders of Securities as of such
February 1 and August 1, and (ii) at such other times as the Trustee may
request in writing, within 30 days after receipt by the Company of any such
request, a list of similar form and content as of a date not more than 15 days
prior to the time such list is requested to be furnished; provided, however,
that if and so long as the Trustee is the Security Registrar for Securities of
a series, no such list need be furnished with respect to such Series of
Securities.
 
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 Holders the form of proxy or other communication, if
  any, specified in such application.
 
  If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Holder 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
 
                                       34
<PAGE>
 
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).
 
SECTION 6.03. Reports by Trustee.
 
  (i) Within 60 days after May 1 of each year commencing with the year 1996,
the Trustee shall mail to each Holder reports concerning the Trustee and its
action under the Indenture as may be required pursuant to the Trust Indenture
Act if and to the extent and in the manner provided pursuant thereto.
 
  (ii) Reports pursuant to this Section shall be transmitted by mail (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 Security of
any series whose name and address appear in the information preserved at the
time by the Trustee in accordance with Section 6.02(i).
 
  (iii) A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Trustee with each securities exchange upon which any
Securities are listed, and also with the Commission. The Company will notify
the Trustee when any Securities are listed on any securities exchange.
 
SECTION 6.04. Reports by Company.
 
  The Company will:
 
    (i) file with the Trustee, within 15 days after the Company is required
  to file the same with the Commission, copies of the annual reports and of
  the information, documents and other reports (or copies of such portions of
  any of the foregoing as the Commission may from time to
  time by rules and regulations prescribe) which the Company may be required
  to file with the Commission pursuant to Section 13 or Section 15(d) of the
  Securities Exchange Act of 1934; or, if the Company is not required to file
  information, documents or reports pursuant to either of said Sections, then
  it will file with the Trustee and the Commission, in accordance with rules
  and regulations prescribed from time to time by the Commission, such of the
  supplementary and periodic information, documents and reports which may be
  required pursuant to Section 13 of the Securities Exchange Act of 1934 in
  respect of a security listed and registered on a national securities
  exchange as may be prescribed from time to time in such rules and
  regulations;
 
    (ii) file with the Trustee and the Commission, in accordance with rules
  and regulations prescribed from time to time by the Commission, such
  additional information, documents and reports with respect to compliance by
  the Company with the conditions and covenants of this Indenture as may be
  required from time to time by such rules and regulations; and
 
 
                                       35
<PAGE>
 
    (iii) transmit by mail to Holders of Securities, in the manner and to the
  extent provided in Section 6.03(ii), within 30 days after the filing
  thereof with the Trustee, such summaries of any information, documents and
  reports required to be filed by the Company pursuant to paragraphs (i) and

                                    REMEDIES
 
SECTION 7.01. Events of Default.
 
  "Event of Default", with respect to 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 administrative or
governmental body), unless it is either inapplicable to a particular series or
it is specifically deleted or modified in the supplemental indenture or Board
Resolution under which such series of Securities is issued or in the form of
Security for such series:
 
 
    (i) the entry of a decree or order by a court having jurisdiction in the
  premises granting relief in respect of the Company in an involuntary case
  under the Federal Bankruptcy Code, adjudging the Company a bankrupt, or
  approving as properly filed a petition seeking reorganization, arrangement,
  adjustment or composition of or in respect of the Company under the Federal
  Bankruptcy Code or any other applicable Federal or State bankruptcy,
  insolvency or other similar law, or appointing a receiver (or other similar
  official) of the Company, or of substantially all of its properties, or
  ordering the winding up or liquidation of its affairs under any such law,
  and the continuance of any such decree or order unstayed and in effect for
  a period of 60 consecutive days; or
 
    (ii) the institution by the Company of proceedings to be adjudicated a
  bankrupt, or the consent of the Company to the institution of bankruptcy
  proceedings against it, or the filing by the Company of a petition or
  answer or consent seeking reorganization or relief under the Federal
  Bankruptcy Code or any other applicable Federal or State bankruptcy,
  insolvency or similar law, or the consent by the Company to the filing of
  any such petition or to the appointment of a receiver, liquidator,
  custodian, assignee, trustee, sequestrator (or other similar official) of
  the Company, or of substantially all of its properties under any such law;
  or
 
    (iii) any other Event of Default provided with respect to Securities of
  that series.
 
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
 
                                       36
<PAGE>
 
Outstanding Securities of such series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if
 
    (i) the Company has paid or deposited with the Trustee a sum sufficient
  to pay
 
      (a) all overdue instalments of interest on all Securities of such
    series,
 
      (b) the principal of and premium, if any, on any Securities of such
    series which have become due otherwise than by such declaration of
    acceleration and interest thereon at the rate or rates prescribed
    therefor by the terms of the Securities of such series,
 
      (c) to the extent that payment of such interest is lawful, interest
    upon overdue instalments of interest at the rate or rates prescribed
    therefor by the terms of the Securities of such series, and
 
      (d) all sums paid or advanced by the Trustee hereunder and the
    reasonable compensation, expenses, disbursements and advances of the
    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 other Defaults with respect to Securities of that series, other
  than the non-payment of the principal of Securities of that series which
  have become due solely by such declaration of acceleration, have been cured
  or waived as provided in Section 7.13.
 
No such recission 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 instalments 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 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
 
                                       37
<PAGE>
 
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,
 
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.
 
SECTION 7.05. Trustee May Enforce Claims Without Possession of Securities.
 
  All rights of action and claims under this Indenture or under the 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.
 
SECTION 7.06. Application of Money Collected.
 
  Any money collected by the Trustee with respect to a series of Securities
pursuant to this Article shall be applied in the following order, at the date
or dates fixed by the Trustee, and, in case of the distribution of such money
on account of principal, premium, if any, or interest, upon presentation of the
Securities of such series or coupons appertaining thereto, if any, or both, as
the case may be, and the notation thereon of the payment if only partially paid
and upon surrender thereof if fully paid:
 
                                       38
<PAGE>
 
    FIRST: To the payment of all amounts due the Trustee under Section 8.07;
 
    SECOND: To the payment of the amounts then due and unpaid upon the
  Securities of such series and coupons for principal, premium, if any, and
  interest, in respect of which or for the benefit of which such money has
  been collected, ratably, without preference or priority of any kind,
  according to the amounts due and payable on Securities of such series and
  coupons, if any, for principal, premium, if any, and interest,
  respectively. The Holders of each series of Securities denominated in ECU,
  any other composite currency or a Foreign Currency and any matured coupons
  relating thereto shall be entitled to receive a ratable portion of the
  amount determined by the Exchange Rate Agent by converting the principal
  amount Outstanding of such series of Securities and matured but unpaid
  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
 
    THIRD: The balance, if any, to the Person or Persons entitled thereto.
 
SECTION 7.07. Limitation on Suits.
 
  No Holder of any Security of any series or any related coupons shall have any
right to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless
 
    (i) such Holder has previously given written notice to the Trustee of a
  continuing 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 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
 
    (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.
 
  The following events shall be "Defaults" with respect to any series of
Securities under this Indenture:
 
    (a) an Event of Default with respect to such series specified in Section
  7.01; or
 
    (b) default in the payment of the principal of or premium, if any, on any
  Security of such series at its Maturity; or
 
    (c) default in the payment of any interest upon any Security of such
  series as and when the same shall become due and payable, and continuance
  of such default for a period of 30 days; or
 
    (d) failure on the part of the Company duly to observe or perform any of
  the other covenants or agreements on its part in the Securities of such
  series or in this Indenture and continuance of such failure for a period of
  sixty days after the date on which written notice of such failure,
 
                                       39
<PAGE>
 
  requiring the Company to remedy the same and stating that such notice is a
  "Notice of Default" hereunder, shall have been given by registered mail to
  the Company by the Trustee, or to the Company and the Trustee by the
  holders of at least 25% in aggregate principal amount of the Securities of
  such series at the time Outstanding, or
 
    (e) any other Default provided with respect to Securities of that Series.
 
SECTION 7.08. Unconditional Right of Holders to Receive Principal, Premium and
Interest.

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, destroyed or stolen Securities or coupons in the last
paragraph of Section 3.06, no right or remedy herein conferred upon or reserved
to the Trustee or to the Holders is intended to be exclusive of any other right
or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent
the concurrent assertion or employment of any other appropriate right or
remedy.
 
SECTION 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 Default shall impair
any such right or remedy or constitute a waiver of any such Default or an
acquiesence 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,
 
 
                                       40
<PAGE>
 
    (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 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
 
    (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 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 extention law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of
any power herein granted to the Trustee, but will suffer and permit the
execution of every such power as though no such law had been enacted.

                                  THE TRUSTEE
 
SECTION 8.01. Certain Duties and Responsibilities.
 
  (i) Except during the continuance of a 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 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
  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 principal of, premium, if any, or
interest on any Security of such series, or any
 
                                       42
<PAGE>
 
related coupons or in the payment of any sinking fund instalment with respect
to Securities of such series the Trustee shall be protected in withholding such
notice if and so long as the board of directors, the executive committee or a
trust committee of directors 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 7.07(d) with respect to
Securities of such series, no such notice to Holders of Securities of such
series shall be given until at least 30 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, a Default or an Event of Default with respect to Securities
of such series.
 
SECTION 8.03. Certain Rights of Trustee.
 
  Except as otherwise provided in Section 8.01:
 
    (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 and
  protection in respect of any action taken, suffered or omitted by it
  hereunder in good faith and in reliance thereon;
 
    (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
  have offered to the Trustee reasonable security or indemnity against the
  costs, expenses and liabilities which might be incurred by it in compliance
  with such request or direction;
 
    (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 and, if so requested to do so by any of the Holders, at the sole
  cost and expense of the Holders;
 
    (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; and
 
    (viii) in the event that the Trustee is also acting as Paying Agent,
  Authenticating Agent or Security Registrar hereunder, the rights and
  protections afforded to the Trustee pursuant to this Article Eight shall
  also be afforded to such Paying Agent, Authenticating Agent or Security
  Registrar.
 
 
                                       43
<PAGE>
 
SECTION 8.04. Not Responsible for Recitals or Issuance of Securities.
 
  The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the
Company, 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.
 
  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
 
                                       44
<PAGE>
 
pursuant to Article Eleven of this Indenture, 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 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
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
 
 
                                       45
<PAGE>
 
    (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 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,
 
                                       46
<PAGE>
 
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, subject nevertheless to its lien, if any, provided for in Section
8.07.
 
  (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.
 
 
                                       47
<PAGE>
 
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 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

Securities shall be subrogated (equally and ratably with the holders of all
indebtedness of the Company which by its express terms is subordinated to
indebtedness of the Company to substantially the same extent as the Securities
are subordinated and is entitled to like rights of subrogation) to the rights
of the holders of Senior Indebtedness to receive payments or distributions of
cash, property or securities of the Company applicable to the Senior
Indebtedness until the principal of and premium, if any, and interest on the
Securities shall be paid in full and no such payments or distributions to
holders of such Senior Indebtedness to which the Holders of the Securities
would be entitled except for the provisions hereof of cash, property or
securities otherwise distributable to the Senior Indebtedness shall, as between
the Company, its creditors, other than the holders of Senior Indebtedness, and
the Holders of the Securities, be deemed to be a payment by the Company to or
on account of the Securities. It is understood that the provisions of this
Article Fourteen are and are intended solely for the purpose of defining the
relative rights of the Holders of the Securities, on the one hand, and
 
                                       56
<PAGE>
 
the 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, as between the Company, its creditors, other than the holders of Senior
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 and creditors of the Company, other than the holders of the
Senior Indebtedness and creditors in respect of General Obligations, nor shall
anything herein or in the Securities prevent the Trustee or the Holder of any
Security from exercising all remedies otherwise permitted by applicable law
upon Default under this Indenture, subject to the rights, if any, under this
Article Fourteen of the holders of Senior Indebtedness and under Section 14.09
of creditors in respect of General Obligations in respect of cash, property or
securities of the Company received upon the exercise of any such remedy. Upon
any payment or distribution of assets of the Company referred to in this
Article Fourteen, the Trustee, subject to the provisions of 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 14.09, the Trustee may request
such Person to furnish evidence to the reasonable 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 respect to the holders of Senior
Indebtedness or creditors in respect of General 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
 
                                       57

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.
 
SECTION 14.03. Payments on Securities Prohibited During Event of Default under
Senior Indebtedness.
 
  In the event and during the continuation of any default in the payment of
principal of, or premium, if any, or interest on, any Senior Indebtedness
beyond any applicable period of grace, or in the event that any event of
default with respect to any Senior Indebtedness shall have occurred and be
continuing, or would occur as a result of the payment referred to hereinafter,
permitting the holders of such Senior Indebtedness (or a trustee on behalf of
the holders thereof) to accelerate the maturity thereof, then, unless and
until such default or event of default shall have been cured or waived or
shall have ceased to exist, no payment of principal of, or premium or interest
on the Securities, or in respect of any redemption, retirement, purchase or
other acquisition of any of the Securities, shall be made by the Company.
 
SECTION 14.04. Payments on Securities Permitted.
 
  Nothing contained in this Indenture or in any of the Securities shall (i)
impair, as between the Company and Holders of Securities, the obligation of
the Company to make, or prevent the Company from making, at any time except as
provided in Sections 14.02, 14.03 and 14.09, payments of principal of or
premium, if any, or interest (including interest accruing subsequent to the
commencement of any proceeding for the bankruptcy or reorganization of the
Company under any applicable bankruptcy, insolvency or similar law now or
hereafter in effect) on the Securities, as and when the same shall become due
and payable in accordance with the terms of the Securities, (ii) affect the
relative rights of the Holders of the Securities and creditors of the Company
other than the holders of the Senior Indebtedness of the Company and the
creditors in respect of General Obligations, (iii) prevent the Holder of any
Security from exercising all remedies otherwise permitted by applicable law
upon default thereunder, subject to the rights, if any, under Article Fourteen
of the holders of Senior Indebtedness and the creditors in respect of General
Obligations in respect of cash, property or 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 prior to such deposit, the
Trustee or such Paying Agent did not have written notice of any event
prohibiting the making of such deposit by the Company.
 
SECTION 14.05. Authorization of Holders to Trustee to Effect Subordination.
 
  Each Holder of a Security by his acceptance thereof authorizes and directs
the Trustee in his behalf to take such action as may be necessary or
appropriate to effectuate the subordination as provided in this Article
Fourteen and appoints the Trustee his attorney-in-fact for any and all such
purposes.
 
SECTION 14.06. Notice to Trustee.
 
  Notwithstanding the provisions of this Article or any other provisions of
the 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 a Responsible Officer of
the Trustee assigned to its Corporate Trustee Administration Department or
such Paying Agent shall have received written notice thereof from the Company
or from the holder of any Senior
 
                                      58
<PAGE>
 
Indebtedness or from the representative of any such holder or from any creditor
in respect of General Obligations.
 
SECTION 14.07. Right of Trustee to Hold Senior Indebtedness or General
Obligations.
 
  The Trustee shall be entitled to all of the rights set forth in this Article
in respect of any Senior Indebtedness or General Obligation at any time held by
it in its individual capacity to the same extent as any other holder of such
Senior Indebtedness or creditor in respect of such General Obligation and
nothing in this Indenture shall be construed to deprive the Trustee of any of
its rights as such holder or creditor.
 
SECTION 14.08. Article Fourteen Not to Prevent Defaults or Events of Default.
 
  The failure to make a payment pursuant to the Securities by reason of any
provision in this Article shall not be construed as preventing the occurrence
of a Default or an Event of Default.
 
SECTION 14.09. Securities to Rank Pari Passu with Existing 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 (including this Indenture and
  the Old Subordinated 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,
  property or securities shall be available for payment or distribution in
  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 or General Obligations) to pay or
  provide for the payment of the General Obligations remaining unpaid, to the
  extent necessary to pay all General Obligations in full, after 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
 
                                       59
<PAGE>
 
  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 and distributions of cash, property and
  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
  (other than creditors in respect of General Obligations) and the Holders of
  Securities be deemed to be a payment or distribution by the Company to or
  on account of the General Obligations.
 
    (vi) The provisions of subsections (iii), (iv) and (v) of this Section
  are and are intended solely for the purpose of defining the relative rights
  of the Holders of the Securities, on the one hand, and the creditors in
  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.

                       REPAYMENT AT THE OPTION OF HOLDERS
 
SECTION 15.01. Applicability of Article.
 
  Securities of any series which are repayable at the option of the Holders
thereof before their Stated Maturity shall be repaid in accordance with 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 a Repayment Date shall be repaid at the applicable
Repayment Price together with interest accrued to such Repayment Date as
specified pursuant to Section 3.01.
 
Section 15.03. Exercise of Option; Notice.
 
  Each Holder desiring to 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 together with written notice of exercise of such
option shall be made at an office or agency located outside the United States
except as otherwise provided 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
 
                                       60
<PAGE>
 
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
be payable only at an office or agency located outside the United States except
as otherwise provided in Section 5.02.
 
  The Company shall execute and the Trustee shall authenticate and deliver
without service charge to the Holder of any Registered Security so surrendered
a new Registered Security or Securities of the same series and tenor of any
authorized denomination specified in the foregoing notice, in an aggregate
principal amount equal to any portion of the principal of the Registered
Security so surrendered which is not to be repaid.
 
  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 Securities (and
all appurtenant unmatured coupons and matured coupons in default) or any
combination thereof of the same series and tenor of any 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 paid; 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.
 
  For all purposes of this Indenture, unless the context otherwise 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 of the
principal of such Security which has been or is to be repaid.
 
Section 15.04. Election of Repayment by Remarketing Entities.
 
  The Company may elect, with respect to Securities of any series which are
repayable at the option of the Holders thereof before their Stated Maturity, at
any time prior to any Repayment Date to designate one or more Remarketing
Entities to purchase, at a price equal to the Repayment Price, Securities of
such series from the Holders thereof who give notice and surrender their Debt
Securities in accordance with Section 15.03.

Section 15.05. Securities Payable on the Repayment Date.
 
  Notice of exercise of the option of repayment having been given and the
Securities so to be repaid having been surrendered as aforesaid, such
Securities shall, unless purchased in accordance with Section 15.04, 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 of such principal amount.

taken at the meeting, and the Trustee shall not have made the first publication
of the notice of such meeting within 21 days after receipt of such request or
shall not thereafter proceed to cause the meeting to be held as provided

Persons entitled to vote such greater percentage in principal amount of the
Outstanding Securities of such series shall constitute a quorum. In the absence

series, be dissolved. In the absence of a quorum in any other case the meeting
may be adjourned for a period of not less than 10 days as determined by the
chairman of the meeting prior to the adjournment of such meeting. In the
absence of a quorum at any such adjourned meeting, such adjourned meeting may

provides may be given by the Holders of a greater percentage in principal
amount of the Outstanding Securities of a series may be adopted at a meeting or

notice, consent, waiver or other Act which this Indenture expressly provides
may be made, given or taken by the Holders of a specified percentage, which is
less than a majority, in principal amount of the Outstanding Securities of a

Holders of such specified percentage in principal amount of the Outstanding
Securities of that series.

Section 16.05. Determination of Voting Rights; Conduct and Adjournment of

  (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,

                                       63
<PAGE>
 
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

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

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

     from time to time in effect and to general principles of equity;

     agreement against payment therefor, the Debt Warrants will constitute
     legal, valid and binding obligations of the Company enforceable in
     accordance with their terms subject, as to enforcement of remedies, to
     applicable bankruptcy, reorganization, insolvency, moratorium or other laws
     affecting creditors' rights generally from time to time in effect and to

                   STATEMENTS REGARDING COMPUTATION OF RATIOS
 
  The ratios of earnings to fixed charges for the Company have been computed on
the basis of the total enterprise (as defined by the Commission) by dividing
earnings before fixed charges and income taxes by fixed charges. Fixed charges
consist principally of interest expense on all long-term and short-term
borrowings, excluding or including interest on deposits as indicated.
