                                THE CORPORATION
 
     The Corporation is a Tennessee corporation incorporated in 1968 and
registered as a bank holding company under the Bank Holding Company Act of 1956,
as amended (the "BHCA"). Through First Tennessee Bank National Association (the
"Bank") and its other subsidiaries, the Corporation provides a broad range of
financial services. At December 31, 1993, the Corporation had consolidated total
assets of approximately $9.6 billion and consolidated total deposits of
approximately $7.1 billion. As of December 31, 1993, the Corporation ranked 63rd
among bank holding companies in the United States and first among bank holding
companies headquartered in Tennessee in terms of total assets.
 
     The Corporation operates principally through the Bank, which as of December
31, 1993 was the largest commercial bank headquartered in Tennessee both in
terms of total assets and deposits. At December 31, 1993, the Bank had total
assets of approximately $9.4 billion and total deposits of approximately $7.0
billion. The Bank conducts a broad range of retail and commercial banking and
fiduciary services and had 211 banking locations at December 31, 1993. The Bank
also offers a comprehensive range of financial services, including bond
broker/agency services, mortgage banking and check clearing, to companies
nationally. Bond broker/agency services provided by the Bank consist primarily
of the sale of bank-eligible securities to other financial institutions.
Subsidiaries of the Corporation and the Bank are engaged primarily in providing
mortgage banking, integrated check processing solutions, discount brokerage,
equipment finance, venture capital, investment management and credit life
insurance.
 
     The Corporation coordinates the financial resources of the consolidated
enterprise and maintains systems of financial, operational and administrative
control that allow coordination of selected policies and activities. The
Corporation derives substantially all of its consolidated total revenues from
the banking business of its subsidiaries. The Corporation's principal executive
offices are located at 165 Madison Avenue, Memphis, Tennessee 38103; telephone:
(901) 523-4444.
 
                                USE OF PROCEEDS
 
     The Corporation intends to use the net proceeds of the sales of the
Securities for general corporate purposes, which may include the reduction of
indebtedness, investments in or extensions of credit to existing and future
subsidiaries and the financing of acquisitions or such other uses as may be set
forth in the accompanying Prospectus Supplement.
 
                CONSOLIDATED RATIOS OF EARNINGS TO FIXED CHARGES
      AND COMBINED FIXED CHARGES AND PREFERRED STOCK DIVIDEND REQUIREMENTS
 
     For purposes of the following ratios, (i) earnings represent income from
continuing operations before income taxes, plus fixed charges, (ii) fixed
charges represent interest expense (excluding interest on deposits where
indicated) plus the estimated interest component of net rental expense and (iii)
combined fixed charges and preferred stock dividend requirements represent
interest expense (excluding interest on deposits where indicated), and an amount
equal to the pre-tax earnings required to meet applicable preferred stock
dividend requirements and the estimated interest component of net rental
expense. There were no shares of preferred stock outstanding during any of the
periods below indicated and therefore the combined ratio of earnings to fixed
charges and preferred stock dividend requirements would have been the same as
below for all periods indicated.

                           SUPERVISION AND REGULATION
 
     The following discussion sets forth certain of the elements of the
comprehensive regulatory framework applicable to bank holding companies and
banks and provides certain specific information relevant to the Corporation and
its subsidiaries. Federal regulation of financial institutions such as the
Corporation and its subsidiaries is intended primarily for the protection of
depositors and the Federal Deposit Insurance Corporation Bank Insurance Fund
rather than shareholders or other creditors. See also "Available Information"
and "Incorporation of Certain Documents by Reference."
 
GENERAL
 
     As a bank holding company, the Corporation is subject to the regulation and
supervision of the Board of Governors of the Federal Reserve System (the
"Federal Reserve Board") under the BHCA. Under the BHCA, bank holding companies
may not in general directly or indirectly acquire the ownership or control of
more than 5% of the voting shares or substantially all of the assets of any
company, including a bank, without the prior approval of the Federal Reserve
Board. The BHCA also restricts the types of activities in which a bank holding
company and its subsidiaries may engage. Generally, activities are limited to
banking and activities found by the Federal Reserve Board to be so closely
related to banking as to be a proper incident thereto.
 
     In addition, the BHCA generally prohibits the Federal Reserve Board from
approving an application by a bank holding company to acquire shares of a bank
or bank holding company located outside the acquiror's principal state of
operations unless such an acquisition is specifically authorized by statute in
the state in which the bank or bank holding company whose shares are to be
acquired is located. Tennessee has adopted legislation that authorizes
nationwide interstate bank acquisitions, subject to certain state law
reciprocity requirements, including the filing of an application with and
approval of the Tennessee Commissioner of Financial Institutions. The Tennessee
Bank Structure Act of 1974 prohibits a bank holding company from acquiring any
bank in Tennessee if the banks that it controls hold 16 1/2% or more of the
total deposits in individual, partnership and corporate demand and other
transaction accounts, savings accounts and time deposits in all federally
insured financial institutions in Tennessee, subject to certain limitations and
exclusions. As of December 31, 1993, the Corporation estimates that its
subsidiary banks (the "Subsidiary Banks") held approximately 12% of such
deposits. Also, under this act, no bank holding company may acquire any bank in
operation for less than five years or begin a de novo bank in any county in
Tennessee with a population, in 1970, of 200,000 or less, subject to certain
exceptions. Under Tennessee law, branch banking is permitted in any county in
the state.
 
     The Subsidiary Banks are subject to supervision and examination by
applicable federal and state banking agencies. The Bank is a national banking
association subject to regulation and supervision by the Comptroller of the
Currency (the "Comptroller") as its primary federal regulator, as is First
Tennessee Bank National Association Mississippi, which is headquartered in
Southaven, Mississippi. The remaining Subsidiary Bank, Peoples and Union Bank,
is a Tennessee state-chartered bank that is not a member of the Federal Reserve
System, and therefore is subject to the regulations of and supervision by the
Federal Deposit Insurance Corporation (the "FDIC") as well as state banking
authorities. In addition, all of the Subsidiary Banks are insured by, and
subject to regulation by, the FDIC. The Subsidiary Banks are subject to various
requirements and restrictions under federal and state law, including
requirements to maintain reserves against deposits, restrictions on the types
and amounts of loans that may be granted and the interest that may be charged
thereon and limitations on the types of investments that may be made, activities
that may be engaged in, and types of services that may be offered. Various
consumer laws and regulations also affect the operations of the Subsidiary
Banks. In addition to the impact of such regulation, commercial banks are
affected significantly by the actions of the Federal Reserve Board as it
attempts to control the money supply and credit availability in order to
influence the economy.

PAYMENT OF DIVIDENDS
 
     The Corporation is a legal entity separate and distinct from its banking
and other subsidiaries. The principal source of cash flow of the Corporation,
including cash flow to pay dividends on its stock or principal (premium, if any)
and interest on debt securities, is dividends from the Subsidiary Banks. There
are statutory and regulatory limitations on the payment of dividends by the
Subsidiary Banks to the Corporation, as well as by the Corporation to its
shareholders.
 
     Each Subsidiary Bank that is a national bank is required by federal law to
obtain the prior approval of the Comptroller for the payment of dividends if the
total of all dividends declared by the board of directors of such Subsidiary
Bank in any year will exceed the total of (i) its net profits (as defined and
interpreted by regulation) for that year plus (ii) the retained net profits (as
defined and interpreted by regulation) for the preceding two years, less any
required transfers to surplus. A national bank also can pay dividends only to
the extent that retained net profits (including the portion transferred to
surplus) exceed bad debts (as defined by regulation).
 
     State-chartered banks are subject to varying restrictions on the payment of
dividends under applicable state laws. With respect to Peoples and Union Bank,
Tennessee law imposes dividend restrictions substantially similar to those
imposed under federal law on national banks, as described above.
 
     If, in the opinion of the applicable federal bank regulatory authority, a
depository institution or a holding company is engaged in or is about to engage
in an unsafe or unsound practice (which, depending on the financial condition of
the depository institution or holding company, could include the payment of
dividends), such authority may require that such institution or holding company
cease and desist from such practice. The federal banking agencies have indicated
that paying dividends that deplete a depository institution's or holding
company's capital base to an inadequate level would be such an unsafe and
unsound banking practice. Moreover, the Federal Reserve Board, the Comptroller
and the FDIC have issued policy statements which provide that bank holding
companies and insured depository institutions generally should only pay
dividends out of current operating earnings.
 
     In addition, under the Federal Deposit Insurance Corporation Improvement
Act of 1991 ("FDICIA"), a FDIC-insured depository institution may not make
capital distributions (including the payment of dividends) or pay any management
fees to its holding company or pay any dividend if it is undercapitalized or if
such payment would cause it to become undercapitalized. See "-- FDICIA."
 
     At December 31, 1993, under dividend restrictions imposed under applicable
federal and state laws, the Subsidiary Banks, without obtaining regulatory
approval, could legally declare aggregate dividends of approximately $168.2
million.
 
     The payment of dividends by the Corporation and the Subsidiary Banks may
also be affected or limited by other factors, such as the requirement to
maintain adequate capital above regulatory guidelines.
 
TRANSACTIONS WITH AFFILIATES
 
     There are various legal restrictions on the extent to which the Corporation
and its nonbank subsidiaries can borrow or otherwise obtain credit from the
Subsidiary Banks. There are also legal restrictions on the Subsidiary Banks'
purchases of or investments in the securities of and purchases of assets from
the Corporation and its nonbank subsidiaries, a Subsidiary Bank's loans or
extensions of credit to third parties collateralized by the securities or
obligations of the Corporation and its nonbank subsidiaries, the issuance of
guarantees, acceptances and letters of credit on behalf of the Corporation and
its nonbank subsidiaries, and certain bank transactions with the Corporation and
its nonbank subsidiaries, or with respect to which the Corporation and its
nonbank subsidiaries act as agent, participate or have a financial interest.
Subject to certain limited exceptions, a Subsidiary Bank (including for purposes
of this paragraph all subsidiaries of such Subsidiary Bank) may not extend
credit to the Corporation or to any other affiliate (other than another
Subsidiary Bank and certain exempted affiliates) in an amount which exceeds 10%
of the Subsidiary Bank's capital stock and surplus and may not extend credit in
the aggregate to all such affiliates in an amount which exceeds 20% of its
capital stock and surplus. Further, there are legal requirements as to the type,
amount and
 
                                        5
<PAGE>   7
 
quality of collateral which must secure such extensions of credit by the
Subsidiary Banks to the Corporation or to such other affiliates. Finally,
extensions of credit and other transactions between a Subsidiary Bank and the
Corporation or other such affiliates must be on terms and under circumstances,
including credit standards, that are substantially the same or at least as
favorable to such Subsidiary Bank as those prevailing at the time for comparable
transactions with non-affiliated companies.
 
CAPITAL ADEQUACY
 
     The Federal Reserve Board has adopted risk-based capital guidelines for
bank holding companies. The minimum guideline for the ratio of total capital
("Total Capital") to risk-weighted assets (including certain off-balance-sheet
items, such as standby letters of credit) is 8%. At least half of the Total
Capital must be composed of common stock, minority interests in the equity
accounts of consolidated subsidiaries, noncumulative perpetual preferred stock
and a limited amount of cumulative perpetual preferred stock, less goodwill and
other intangible assets, subject to certain exceptions ("Tier 1 Capital"). The
remainder may consist of qualifying subordinated debt, certain types of
mandatory convertible securities and perpetual debt, other preferred stock and a
limited amount of loan loss reserves. At December 31, 1993, the Corporation's
consolidated Tier 1 Capital and Total Capital ratios were 9.60% and 12.14%,
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 1 Capital to average assets, less goodwill and certain
other intangible assets subject to certain exceptions (the "Leverage Ratio"), of
3% for bank holding companies that meet certain specific criteria, including
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 at least 100 to 200 basis points. The Corporation's Leverage Ratio at
December 31, 1993 was 6.55%. 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 1
Capital leverage ratio" (deducting all intangibles) and other indicia of capital
strength in evaluating proposals for expansion or new activities.
 
     Each of the Subsidiary Banks is subject to risk-based and leverage capital
requirements similar to those described above adopted by the Comptroller or the
FDIC, as the case may be. The Corporation believes that each of the Subsidiary
Banks was in compliance with applicable minimum capital requirements as of
December 31, 1993. Neither the Corporation nor any of the Subsidiary Banks has
been advised by any federal banking agency of any specific minimum Leverage
Ratio requirement applicable to it.
 
     Failure to meet capital guidelines 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 and in certain circumstances
to the appointment of a conservator or receiver. See "-- FDICIA."
 
     All of the federal banking agencies have proposed regulations that would
add an additional risk-based capital requirement based upon the amount of an
institution's exposure to interest rate risk.
 
HOLDING COMPANY STRUCTURE AND SUPPORT OF SUBSIDIARY BANKS
 
     Because the Corporation is a holding company, its right to participate in
the assets of any subsidiary upon the latter's liquidation or reorganization
will be subject to the prior claims of the subsidiary's creditors (including
depositors in the case of the Subsidiary Banks) except to the extent that the
Corporation may itself be a creditor with recognized claims against the
subsidiary. In addition, depositors of a bank, and the FDIC as their subrogee,
would be entitled to priority over other creditors in the event of liquidation
of a bank subsidiary.
 
     Under Federal Reserve Board policy, the Corporation is expected to act as a
source of financial strength to, and to commit resources to support, each of the
Subsidiary Banks. This support may be required at times when, absent such
Federal Reserve Board policy, the Corporation may not be inclined to provide it.
In addition, any capital loans by a bank holding company to any of its
subsidiary banks are subordinate in right of
 
                                        6
<PAGE>   8
 
payment to deposits and to certain other indebtedness of such subsidiary bank.
In the event of a bank holding company's bankruptcy, any commitment by the bank
holding company to a federal bank regulatory agency to maintain the capital of a
subsidiary bank will be assumed by the bankruptcy trustee and entitled to a
priority of payment.
 
CROSS-GUARANTEE LIABILITY
 
     Under the Federal Deposit Insurance Act (the "FDIA"), a depository
institution insured by the FDIC can be held liable for any loss incurred by, or
reasonably expected to be incurred by, the FDIC after August 9, 1989 in
connection with (i) the default of a commonly controlled FDIC-insured depository
institution or (ii) any assistance provided by the FDIC to any commonly
controlled FDIC-insured depository institution "in danger of default." "Default"
is defined generally as the appointment of a conservator or receiver and "in
danger of default" is defined generally as the existence of certain conditions
indicating that a default is likely to occur in the absence of regulatory
assistance. The FDIC's claim for damages is superior to claims of shareholders
of the insured depository institution or its holding company but is subordinate
to claims of depositors, secured creditors and holders of subordinated debt
(other than affiliates) of the commonly controlled insured depository
institution. The Subsidiary Banks are subject to these cross-guarantee
provisions. As a result, any loss suffered by the FDIC in respect of any of the
Subsidiary Banks would likely result in assertion of the cross-guarantee
provisions, the assessment of such estimated losses against the Corporation's
other Subsidiary Banks and a potential loss of the Corporation's investment in
such other Subsidiary Banks.
 
FDICIA
 
     FDICIA, which was enacted on December 19, 1991, substantially revised the
depository institution regulatory and funding provisions of the FDIA and made
revisions to several other federal banking statutes. Among other things, FDICIA
requires the federal banking regulators to take "prompt corrective action" in
respect of FDIC-insured depository institutions that do not meet minimum capital
requirements. FDICIA establishes five capital tiers: "well capitalized,"
"adequately capitalized," "undercapitalized," "significantly undercapitalized"
and "critically undercapitalized." Under applicable regulations, an FDIC-insured
depository institution is defined to be well capitalized if it maintains a
Leverage Ratio of at least 5%, a risk-adjusted Tier 1 Capital Ratio of at least
6% and a Total Capital Ratio of at least 10% and is not subject to a directive,
order or written agreement to meet and maintain specific capital levels. An
insured depository institution is defined to be adequately capitalized if it
meets all of its minimum capital requirements as described above. An insured
depository institution will be considered undercapitalized if it fails to meet
any minimum required measure, significantly undercapitalized if it has a Total
Risk-Based Capital Ratio of less than 6%, a Tier 1 Risk-Based Capital Ratio of
less than 3% or a Leverage Ratio of less than 3% and critically undercapitalized
if it fails to maintain a level of tangible equity equal to at least 2% of total
assets. An insured depository institution may be deemed to be in a
capitalization category that is lower than is indicated by its actual capital
position if it receives an unsatisfactory examination rating.
 
     FDICIA generally prohibits an FDIC-insured depository institution from
making any capital distribution (including payment of dividends) or paying any
management fee to its holding company if the depository institution would
thereafter be undercapitalized. Undercapitalized depository institutions are
subject to restrictions on borrowing from the Federal Reserve System. In
addition, undercapitalized depository institutions are subject to growth
limitations and are required to submit capital restoration plans. A depository
institution's holding company must guarantee the capital plan, up to an amount
equal to the lesser of 5% of the depository institution's assets at the time it
becomes undercapitalized or the amount of the capital deficiency when the
institution fails to comply with the plan for the plan to be accepted by the
applicable federal regulatory authority. The federal banking agencies may not
accept a capital plan without determining, among other things, that the plan is
based on realistic assumptions and is likely to succeed in restoring the
depository institution's capital. If a depository institution fails to submit an
acceptable plan, it is treated as if it is significantly undercapitalized.
 
     Significantly undercapitalized depository institutions may be subject to a
number of requirements and restrictions, including orders to sell sufficient
voting stock to become adequately capitalized, requirements to
 
                                        7
<PAGE>   9
 
reduce total assets and cessation of receipt of deposits from correspondent
banks. Critically undercapitalized depository institutions are subject to
appointment of a receiver or conservator, generally within 90 days of the date
on which they become critically undercapitalized.
 
     The Corporation believes that at December 31, 1993 all of the Subsidiary
Banks were well capitalized under the criteria discussed above.
 
     Various other legislation, including proposals to revise the bank
regulatory system and to limit the investments that a depository institution may
make with insured funds, is from time to time introduced in Congress.
 
BROKERED DEPOSITS AND "PASS-THROUGH" INSURANCE
 
     The FDIC has adopted regulations under FDICIA governing the receipt of
brokered deposits and "pass-through" insurance. Under the regulations, a bank
cannot accept or rollover or renew brokered deposits unless (i) it is well
capitalized or (ii) it is adequately capitalized and receives a waiver from the
FDIC. A bank that cannot receive brokered deposits also cannot offer
"pass-through" insurance on certain employee benefit accounts. Whether or not it
has obtained such a waiver, an adequately capitalized bank may not pay an
interest rate on any deposits in excess of 75 basis points over certain
prevailing market rates specified by regulation. There are no such restrictions
on a bank that is well capitalized. Because it believes that all the Subsidiary
Banks were well capitalized as of December 31, 1993, the Corporation believes
the brokered deposits regulation will have no present effect on the funding or
liquidity of any of the Subsidiary Banks.
 
FDIC INSURANCE PREMIUMS
 
     The Subsidiary Banks are required to pay semiannual FDIC deposit insurance
assessments. As required by FDICIA, the FDIC adopted a risk-based premium
schedule which has increased the assessment rates for most FDIC insured
depository institutions. Under the new schedule, the premiums initially range
from $.23 to $.31 for every $100 of deposits. Each financial institution is
assigned to one of three capital groups -- well capitalized, adequately
capitalized or undercapitalized -- and further assigned to one of three
subgroups within a capital group, on the basis of supervisory evaluations by the
institution's primary federal and, if applicable, state supervisors and other
information relevant to the institution's financial condition and the risk posed
to the applicable FDIC deposit insurance fund. The actual assessment rate
applicable to a particular institution will, therefore, depend in part upon the
risk assessment classification so assigned to the institution by the FDIC.
 
     The FDIC is authorized by federal law to raise insurance premiums in
certain circumstances. Any increase in premiums would have an adverse effect on
the Subsidiary Banks' and the Corporation's earnings.
 
     Under the FDIA, insurance of deposits may be terminated by the FDIC upon a
finding that the institution has engaged in unsafe and unsound practices, is in
an unsafe or unsound condition to continue operations or has violated any
applicable law, regulation, rule, order or condition imposed by a federal bank
regulatory agency.
 
DEPOSITOR PREFERENCE
 
     The Omnibus Budget Reconciliation Act of 1993 provides that deposits and
certain claims for administrative expenses and employee compensation against an
insured depository institution would be afforded a priority over other general
unsecured claims against such an institution, including the Senior Securities,
in the "liquidation or other resolution" of such an institution by any receiver.
 
                         DESCRIPTION OF DEBT SECURITIES
 
     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 the Debt Securities
offered hereunder (the "Offered Debt Securities"), including the nature of any
variations
 
                                        8
<PAGE>   10
 
from the following general provisions applicable to such Offered Debt
Securities, will be described in a Prospectus Supplement relating to such
Offered Debt Securities.
 
     Senior Debt Securities are to be issued under an Indenture (the "Senior
Indenture"), between the Corporation and the trustee named in the applicable
Prospectus Supplement as the trustee therefor (the "Senior Trustee").
Subordinated Debt Securities are to be issued under an Indenture (the
"Subordinated Indenture"), between the Corporation and The First National Bank
of Chicago as the trustee therefor (the "Subordinated Trustee"). Copies of the
forms of the Senior Indenture and the Subordinated Indenture have been filed as
exhibits to the Registration Statement of which this Prospectus is a part. The
Senior Indenture and the Subordinated Indenture are sometimes herein referred to
collectively as the "Indentures" and the Senior Trustee and the Subordinated
Trustee are sometimes herein referred to collectively as the "Trustees". The
following summaries of certain provisions of the Senior Debt Securities, the
Subordinated Debt Securities, the Senior Indenture and the Subordinated
Indenture, as modified or superseded by any applicable Prospectus Supplement,
are brief summaries of certain provisions thereof, do not purport to be complete
and are subject to, and are qualified in their entirety by reference to, all the
provisions of the Indenture applicable to a particular series of Debt Securities
(the "Applicable Indenture"), including the definitions therein of certain
terms. Whenever particular provisions or defined terms in one or both of the
Indentures are referred to, such provisions or defined terms are incorporated
herein by reference. Section references used herein are references to the
Applicable Indenture. Capitalized terms not otherwise defined herein shall have
the meaning given to them in the Applicable Indenture.
 
GENERAL
 
     The Debt Securities will be limited to the aggregate initial offering price
specified on the cover page of this Prospectus and will be direct, unsecured
obligations of the Corporation. The Debt Securities will not be deposits or
other obligations of a savings association or a bank and will not be insured by
the FDIC or any other governmental agency.
 
     The Indentures do not limit the aggregate principal amount of Debt
Securities or of any particular series of Debt Securities which may be issued
thereunder and provide that Debt Securities issued thereunder may be issued from
time to time in one or more series, in each case with the same or various
maturities, at par or at a discount. (Section 301). The Indentures do not limit
the amount of other debt (including additional Senior Indebtedness or Other
Financial Obligations, each as defined in the Subordinated Indenture) that may
be issued by the Corporation and do not contain financial or similar restrictive
covenants. The Corporation expects from time to time to incur additional
indebtedness constituting Senior Indebtedness and Other Financial Obligations.
The Indentures provide that there may be more than one trustee (each, an
"Applicable Trustee") under the Indentures with respect to different series of
Debt Securities.
 
     Because the Corporation is a holding company and a legal entity separate
and distinct from its subsidiaries, the rights of the Corporation to participate
in any distribution of assets of any subsidiary upon its liquidation of assets
or reorganization or otherwise (and thus the ability of Holders of Debt
Securities to benefit indirectly from such distribution) would be subject to the
prior claims of creditors of that subsidiary, except to the extent that the
Corporation itself may be a creditor of that subsidiary with recognized claims.
Claims on the Corporation's Subsidiary Banks by creditors other than the
Corporation include substantial obligations with respect to deposit liabilities
(who have priority in liquidation) and federal funds purchased, securities sold
under repurchase agreements, other short-term borrowing and various other
financial obligations.
 
     The Indentures do not contain any provision intended to provide protection
to Holders of Debt Securities against a sudden or dramatic decline in credit
quality of the Corporation that could result from a takeover, recapitalization,
special dividend or other restructuring, although the Corporation's (or a third
party's) ability to engage in such transactions may be regulated or limited by
various bank regulatory agencies.
 
     Reference is made to the applicable Prospectus Supplement for the following
terms of the Offered Debt Securities offered thereby: (1) the title of the
Offered Debt Securities; (2) whether the Offered Debt Securities are Senior Debt
Securities or Subordinated Debt Securities; (3) any limit upon the aggregate
 
                                        9
<PAGE>   11
 
principal amount of the Offered Debt Securities and the percentage of such
principal amount at which such Offered Debt Securities may be issued; (4) the
date or dates on which the principal of the Offered Debt Securities is scheduled
to become payable (the "Stated Maturity"); (5) the rate or rates(which may be
fixed or variable) per annum at which the Offered Debt Securities will bear
interest, or the method of determining such rate or rates, if any, the date or
dates from which any such interest will accrue, the Interest Payment Dates on
which any such interest will be payable, the Regular Record Date for the
interest payable on any Interest Payment Date, the Person to whom interest or
principal on any Offered Debt Security of such series will be payable, if other
than the Person in whose name that Offered Debt Security (or one or more
predecessor Debt Securities) is registered at the close of business on the
Regular Record Date for such interest and the extent to which, or the manner in
which, any interest payable on a permanent global Offered Debt Security on an
Interest Payment Date will be paid; (6) if other than the location specified in
this Prospectus, the place or places where the principal of and premium, if any,
and interest on the Offered Debt Securities will be payable; (7) the period or
periods within which, the price or prices at which and the terms and conditions
upon which the Offered Debt Securities will, pursuant to any mandatory sinking
fund provisions or otherwise, or may, pursuant to any optional sinking fund
provisions or otherwise, be redeemed in whole or in part by the Corporation; (8)
the period or periods within which, the price or prices at which and the terms
and conditions upon which the Offered Debt Securities may be repaid, in whole or
in part, at the option of the Holders thereof; (9) if other than denominations
of $1,000 and any integral multiple thereof, the denominations in which the
Offered Debt Securities shall be issuable; (10) if other than the principal
amount thereof, the portion of the principal amount of the Offered Debt
Securities which shall be payable upon declaration of acceleration of the
Maturity thereof; (11) the currency or currency unit of payment of principal and
premium, if any, and interest on such Offered Debt Securities, and any index
used to determine the amount of payment of principal or premium, if any, and
interest on such Offered Debt Securities; (12) whether the Offered Debt
Securities are to be issuable in permanent global form and, in such case, the
initial depositary with respect thereto and the circumstances under which such
permanent global Debt Security may be exchanged; (13) whether the subordination
provisions summarized below, or different subordination provisions, including a
different definition of "Senior Indebtedness," "Entitled Persons," "Existing
Subordinated Indebtedness" or "Other Financial Obligations," shall apply to the
Offered Debt Securities that are Subordinated Debt Securities; (14) in the case
of Subordinated Debt Securities, whether the conversion provisions summarized
below or different conversion provisions, shall apply to the Offered Debt
Securities that are Subordinated Debt Securities, and the Initial Conversion
Price, the Initial Conversion Date and the Final Conversion Date therefor and
any other terms relating to the conversion thereof into Common Stock of the
Corporation; and (15) any other terms of the Offered Debt Securities not
specified in this Prospectus. (Section 301).
 
FORM, REGISTRATION AND TRANSFER
 
     Unless otherwise indicated in the applicable Prospectus Supplement,
principal, premium, if any, and interest, if any, on the Debt Securities will be
payable, and the Debt Securities will be transferable, at the agency or office
of the Corporation maintained for such purpose in the Borough of Manhattan, The
City of New York except that interest may be paid at the option of the
Corporation by check mailed to the address of the Holder entitled thereto as it
appears on the Security Register. (Sections 301, 305 and 1002).
 
     The Corporation, the Trustee and any agent of the Corporation or Trustee
may treat the Person in whose name an Offered Debt Security is registered as the
owner for all purposes, including for the purpose of receiving payment of
principal (and premium, if any) and interest on such Offered Debt Security.
 
     Unless otherwise indicated in the applicable Prospectus Supplement, the
Debt Securities will be issued only in fully registered form, without coupons
(the "Registered Securities"), in denominations of $1,000 and any integral
multiple thereof. (Section 302). The Indentures provide that Offered Debt
Securities of any series may be issuable in permanent global form. (Section
301). No service charge will be made for any registration of transfer or
exchange of the Debt Securities, but the Corporation may require payment of a
sum sufficient to cover any tax or other governmental charge payable in
connection therewith. (Section 305).
 
                                       10
<PAGE>   12
 
     Both Senior Debt Securities and Subordinated Debt Securities may be issued
as Original Issue Discount Securities to be offered and sold at a substantial
discount below their stated principal amount. Federal income tax consequences
and other special considerations applicable to any such Original Issue Discount
Securities will be described in the applicable Prospectus Supplement. "Original
Issue Discount Security" means any Security which provides for an amount less
than the principal amount thereof to be due and payable upon the declaration of
acceleration of the Maturity thereof in accordance with the terms of the
Applicable Indenture. (Section 101).
 
     Reference is made to the applicable Prospectus Supplement relating to any
series of Offered Debt Securities that are Original Issue Discount Securities
for the particular provisions relating to acceleration of the Maturity of a
portion of the principal amount of such series of Original Issue Discount
Securities upon the occurrence of an Event of Default and the continuation
thereof.
 
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 ("Global Securities") that will be
deposited with, or on behalf of, a depositary (the "Global Depositary")
identified in the applicable Prospectus Supplement. 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 individual
certificates evidencing Debt Securities in definitive form represented thereby,
a Global Security may not be transferred except as a whole by the Global
Depositary for such Global Security to a nominee of such Global Depositary or by
a nominee of such Global Depositary to such Global Depositary or another nominee
of such Global Depositary or by such Global Depositary or any such nominee to a
successor of such Global Depositary or a nominee of such successor. (Section
305).
 
     The specific terms of the depositary arrangement with respect to any Debt
Securities of a series will be described in the applicable Prospectus
Supplement. The Corporation anticipates that the following provisions will
generally apply to all depositary arrangements although no assurance can be
given that such will be the case.
 
     Upon the issuance of a Global Security, the Global Depositary or its
nominee will credit, on its book-entry registration and transfer system, the
respective principal amounts of the Debt Securities represented by such Global
Security to the accounts of institutions that have accounts with such Global
Depositary ("participants"). The accounts to be credited shall be designated by
the underwriters or agents of such Debt Securities or by the Corporation, if
such Debt Securities are offered and sold directly by the Corporation. Ownership
of beneficial interests in a Global Security will be limited to 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 Global
Depositary or its nominee for such Global Security (with respect to interests of
participants) and the records of participants (with respect to 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 Global Depositary, or its nominee, is the owner of a Global
Security, such Global 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 Applicable Indenture. Except as set
forth below, owners of beneficial interests in a Global Security will not be
entitled to have Debt Securities represented by such Global Security registered
in their names, will not receive or be entitled to receive physical delivery of
Debt Securities of such series in definitive form and will not be considered the
owners or holders thereof under the Applicable Indenture.
 
     Subject to the restrictions discussed under "Description of Debt
Securities -- Form, Registration and Transfer," payment of principal of,
premium, if any, and interest, if any, on, Debt Securities registered in the
name of or held by a Global Depositary or its nominee will be made to the Global
Depositary or its nominee, as the case may be, as the registered owner or the
holder of the Global Security representing such Debt Securities. None of the

such Debt Securities will have any responsibility or liability for any aspect of
the records relating to or payments made on account of beneficial ownership
interests in a Global Security for such Debt Securities or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.
 
     The Corporation expects that the Global Depositary for Debt Securities of a
series, upon receipt of any payment of principal, premium, if any, or any
interest in respect of a permanent Global Security, will credit immediately
participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of such Global Security
as shown on the records of such Global Depositary or its nominee. The
Corporation 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," and will be the responsibility of such participants. Receipt
by owners of beneficial interests in a temporary Global Security of payments in
respect of such temporary Global Security will be subject to the restrictions
discussed under "Description of Debt Securities -- Form, Registration and
Transfer" above.
 
     If the Global Depositary for Debt Securities of a series is at any time
unwilling, unable or ineligible to continue as Global Depositary and a successor
Global Depositary is not appointed by the Corporation within 90 days or an Event
of Default has occurred and is continuing, the Corporation will issue Debt
Securities of such series in definitive form in exchange for the Global Security
or Securities representing the Debt Securities of such series. In addition, the
Corporation may at any time and in its sole discretion, subject to any
limitations described in the applicable Prospectus Supplement, determine not to
have any Debt Securities of a series represented by one or more Global
Securities and, in such event, will issue Debt Securities of such series in
definitive form in exchange for the Global Security or Securities representing
such Debt Securities. Further, if the Corporation 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 Corporation and the Global 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 applicable 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).
 
SUBORDINATION OF THE SUBORDINATED DEBT SECURITIES
 
     The payment of the principal of and interest on the Subordinated Debt
Securities will, to the extent set forth in the Subordinated Indenture, be
subordinated in right of payment to the prior payment in full of all Senior
Indebtedness. Unless otherwise specified in the applicable Prospectus
Supplement, in certain events of insolvency, the payment of the principal of and
interest on the Subordinated Debt Securities will, to the extent set forth in
the Subordinated Indenture, also be effectively subordinated in right of payment
to the prior payment in full of all Other Financial Obligations. Upon any
payment or distribution of assets to creditors upon any liquidation,
dissolution, winding up, reorganization, assignment for the benefit of
creditors, marshalling of assets or any bankruptcy, insolvency or similar
proceedings of the Corporation, the holders of all Senior Indebtedness will
first be entitled to receive payment in full of all amounts due or to become due
thereon before the Holders of the Subordinated Debt Securities will be entitled
to receive any payment in respect of the principal of or interest on the
Subordinated Debt Securities (Section 402 of the Subordinated Indenture). If
upon any such payment or distribution of assets to creditors, there remains,
after giving effect to such subordination provisions in favor of the holders of
Senior Indebtedness, any amount of cash, property or securities available for
payment or distribution in respect of Subordinated Debt Securities (defined in
the Subordinated Indenture as "Excess Proceeds") and if, at such time, any
Entitled Persons (as defined in the Subordinated Indenture) in respect of Other
Financial Obligations have not received payment in full of all amounts due or to
become due on or in respect of such Other Financial Obligations, then such
Excess Proceeds shall first be applied to pay or provide for the payment in full
of such Other Financial Obligations before any payment or distribution may be
made in respect of the Subordinated Debt Securities (and other
 
                                       12
<PAGE>   14
 
securities ranking pari passu in respect of payment). (Section 1415 of the
Subordinated Indenture). In the event of the acceleration of the Maturity of any
Subordinated Debt Securities, the holders of all Senior Indebtedness will first
be entitled to receive payment in full of all amounts due thereon before the
Holders of the Subordinated Debt Securities will be entitled to receive any
payment upon the principal of or interest on the Subordinated Debt Securities.
No payments on account of the principal of, or premium, if any, or interest on
the Subordinated Debt Securities or on account of the purchase or acquisition
thereof shall be made if there shall have occurred and be continuing a default
in any payment with respect to Senior Indebtedness, or an event of default with
respect to Senior Indebtedness permitting the holders thereof to accelerate the
maturity thereof, or if any judicial proceeding shall be pending with respect to
any such default. (Section 1404 of the Subordinated Indenture).
 
     By reason of such subordination in favor of the holders of Senior
Indebtedness, in the event of insolvency, creditors of the Corporation who are
not holders of Senior Indebtedness or Holders of the Subordinated Debt
Securities may recover less, ratably, than the holders of Senior Indebtedness
and may recover more, ratably, than the Holders of the Subordinated Debt
Securities. By reason of the obligation of the Holders of Subordinated Debt
Securities to pay over any Excess Proceeds to Entitled Persons in respect to
Other Financial Obligations, in the event of insolvency, holders of Existing
Subordinated Indebtedness may recover less, ratably, than Entitled Persons in
respect of Other Financial Obligations and may recover more, ratably, than the
Holders of Subordinated Debt Securities (other than Existing Subordinated
Indebtedness).
 
     Unless otherwise specified in the applicable Prospectus Supplement, "Senior
Indebtedness" of the Corporation is defined in the Subordinated Indenture to
mean the principal of, premium, if any, and interest on (1) all indebtedness of
the Corporation (including indebtedness of others guaranteed by the
Corporation), other than the Subordinated Debt Securities and obligations on
account of Existing Subordinated Indebtedness, whether outstanding on the date
of execution of the Indenture or thereafter created, incurred or assumed which
is (i) for money borrowed or (ii) evidenced by a note or similar instrument
given in connection with the acquisition of any business, properties or assets
of any kind, and (2) amendments, renewals, extensions, modifications or
refundings of any such indebtedness, unless in any case in the instrument
creating or evidencing such indebtedness or pursuant to which the same is
outstanding it is provided that such indebtedness is not superior in right of
payment to the Subordinated Debt Securities or is to rank pari passu with or
subordinate to the Subordinated Debt Securities. (Section 101 of the
Subordinated Indenture).
 
     Unless otherwise specified in the applicable Prospectus Supplement, "Other
Financial Obligations" means (a) all obligations of the Corporation under direct
credit substitutes, (b) obligations of, or any such obligation directly or
indirectly guaranteed by, the Corporation for purchased money or funds, (c) any
deferred obligation of, or any such obligation directly or indirectly guaranteed
by, the Corporation incurred in connection with the acquisition of any business,
properties or assets not evidenced by a note or similar instrument given in
connection therewith, and (d) all obligations of the Corporation to make payment
pursuant to the terms of financial instruments, such as (1) securities contracts
and foreign currency exchange contracts, (2) derivative instruments, such as
swap agreements (including interest rate and foreign exchange rate swap
agreements), cap agreements, floor agreements, collar agreements, interest rate
agreements, foreign exchange rate agreements, options, commodity futures
contracts, commodity option contracts, and (3) in the case of both (1) and (2)
above, similar financial instruments, other than (x) obligations on account of
Senior Indebtedness, and (y) obligations on account of indebtedness for money
borrowed ranking pari passu with or subordinate to the Subordinated Debt
Securities. Unless otherwise specified in the applicable Prospectus Supplement
relating to the particular series of Subordinated Debt Securities offered
thereby, "Entitled Person" means any person who is entitled to payment pursuant
to the terms of Other Financial Obligations. (Section 101 of the Subordinated
Indenture).
 
     Unless otherwise specified in the applicable Prospectus Supplement,
"Existing Subordinated Indebtedness" means the obligations of the Corporation
under securities issued pursuant to the indenture, dated as of June 1, 1987,
between the Corporation and Security Pacific National Trust Company (New York),
as trustee, relating to the Corporation's 10 3/8% Subordinated Capital Notes due
1999 (the "Subordinated Capital Notes"). (Section 101 of the Subordinated
Indenture). As of the date of this Prospectus, there was outstanding
approximately $75.0 million aggregate principal amount of Existing Subordinated
Indebtedness.
 
                                       13
<PAGE>   15
 
     The Corporation's obligations under the Subordinated Debt Securities shall
rank pari passu in right of payment with each other and with the Existing
Subordinated Indebtedness, subject (unless otherwise specified in the applicable
Prospectus Supplement relating to the particular series of Subordinated Debt
Securities offered thereby) to the obligations of the Holders of Subordinated
Debt Securities (other than Existing Subordinated Indebtedness) to pay over any
Excess Proceeds to Entitled Persons in respect of Other Financial Obligations as
provided in the Subordinated Indenture.
 
     The applicable Prospectus Supplement may further describe the provisions,
if any, applicable to the subordination of the Subordinated Debt Securities of a
particular series offered thereby.
 
CONVERSION OF THE SUBORDINATED DEBT SECURITIES
 
     If so specified in the applicable Prospectus Supplement, Subordinated Debt
Securities will be convertible into Common Stock of the Corporation prior to
redemption during the time period specified in the applicable Prospectus
Supplement, initially at the Initial Conversion Price therefor specified in such
Prospectus Supplement ("Convertible Subordinated Debt Security"). (Section 1501
of the Subordinated Indenture).
 
     The conversion price will be subject to adjustment in certain events,
including (i) dividends (and other distributions) payable in Common Stock on any
class of capital stock of the Corporation, (ii) the issuance to all holders of
Common Stock of rights or warrants entitling them to subscribe for or purchase
Common Stock at less than the current market price (as defined), (iii)
subdivisions, combinations and reclassifications of Common Stock, and (iv)
distributions to all holders of Common Stock of evidences of indebtedness of the
Corporation or assets (including securities, but excluding those dividends,
rights, warrants and distributions referred to above and dividends and
distributions paid in cash out of the retained earnings of the Corporation). In
addition to the foregoing adjustments, the Corporation will be permitted to make
such reductions in the conversion price as it considers to be advisable in order
that any event treated for Federal income tax purposes as a dividend of stock or
stock rights will not be taxable to the holders of the Common Stock. (Section
1504 of the Subordinated Indenture). In case of certain consolidations or
mergers to which the Company is a party or the transfer of substantially all of
the assets of the Corporation, each Convertible Subordinated Debt Security then
outstanding would, without the consent of any Holders of such Convertible
Subordinated Debt Security, become convertible only into the kind and amount of
securities, cash and other property receivable upon the consolidation, merger or
transfer by a holder of the number of shares of Common Stock into which such
Convertible Subordinated Debt Security might have been converted immediately
prior to such consolidation, merger or transfer (assuming such holder of Common
Stock failed to exercise any rights of election and received per share the kind
and amount received per share by a plurality of non-electing shares). (Section
1512 of the Subordinated Indenture). Generally no adjustments to the conversion
price will be required to be made until cumulative adjustments amount to 1% or
more of the conversion price as last adjusted. (Section 1505 of the Subordinated
Indenture).
 
     Fractional shares of Common Stock are not to be issued upon conversion,
but, in lieu thereof, the Corporation will pay a cash adjustment based upon
market price (as determined by the Board of Directors). (Section 1504 of the
Subordinated Indenture). Convertible Subordinated Debt Securities surrendered
for conversion during the period from the close of business on any Regular
Record Date next preceding any Interest Payment Date to the opening of business
on such Interest Payment Date (except Convertible Subordinated Debt Securities
called for redemption on a Redemption Date within such period) must be
accompanied by payment of an amount equal to the interest thereon which the
registered Holder is to receive. If any Convertible Subordinated Debt Security
is converted after any Regular Record Date and on or prior to the next
succeeding Interest Payment Date (other than any Convertible Subordinated Debt
Security whose Maturity is prior to such Interest Payment Date), interest whose
Stated Maturity is on such Interest Payment Date shall be payable on such
Interest Payment Date notwithstanding such conversion, and such interest
(whether or not punctually paid or duly provided for) shall be paid to the
Person in whose name that Convertible Subordinated Debt Security (or one or more
Predecessor Securities) is registered at the close of business on such Regular
Record Date. Except where Convertible Subordinated Debt Securities surrendered
for conversion must be accompanied by payment as described above, no interest on
converted Convertible Subordinated Debt Securities will be payable by the
Company on any Interest Payment Date subsequent to
 
                                       14
<PAGE>   16
 
the date of conversion. No other payment or adjustment for interest or dividends
is to be made upon conversion. (Sections 307 and 1503 of the Subordinated
Indenture).
 
     If at any time the Corporation makes a distribution of property to its
shareholders which would be taxable to such shareholders as a dividend for
Federal income tax purposes (e.g., distributions of evidences of indebtedness or
assets of the Corporation, but generally not stock dividends or rights to
subscribe for Common Stock) and, pursuant to the anti-dilution provisions of the
Subordinated Indenture, the conversion price of Convertible Subordinated Debt
Securities is reduced, such reduction may be deemed to be the payment of a
taxable dividend to holders of Convertible Subordinated Debt Securities.
 
LIMITATION ON DISPOSITION OF VOTING STOCK OF PRINCIPAL SUBSIDIARY BANKS
 
     The Senior Indenture contains a covenant by the Corporation that it will
not sell, assign, transfer, grant a security interest in or otherwise dispose of
any shares of, securities convertible into or options, warrants or rights to
subscribe for or purchase shares of, Voting Stock (other than directors'
qualifying shares) of any Principal Subsidiary Bank and that it will not permit
any Principal Subsidiary Bank to issue (except to the Corporation) shares of,
securities convertible into, or options, warrants or rights to subscribe or
purchase shares of, Voting Stock, except for sales, assignments, transfers,
grants of security interests or other dispositions which: (1) are for fair
market value (as determined by the Board of Directors of the Corporation) and,
after giving effect to such dispositions and to any potential dilution, the
Corporation will own not less than 80 percent of the shares of Voting Stock of
such Principal Subsidiary Bank; (2) are made in compliance with an order of a
court or regulatory authority of competent jurisdiction, a condition imposed by
any such court or authority permitting the acquisition by the Corporation,
directly or indirectly, of any other bank or entity the activities of which are
legally permissible for a bank holding company or a subsidiary thereof to engage
in, or an undertaking made to such authority in connection with such an
acquisition (provided that the assets of the bank or entity being acquired and
its consolidated subsidiaries equal or exceed 75% of the assets of such
Principal Subsidiary Bank or such Subsidiary owning, directly or indirectly, any
shares of voting stock of such Principal Subsidiary Bank and its respective
consolidated Subsidiaries on the date of acquisition); or (3) are made to the
Corporation or any Wholly-Owned Subsidiary if such Wholly-Owned Subsidiary
agrees to be bound by this covenant and the Corporation agrees to maintain such
Wholly-Owned Subsidiary as a Wholly-Owned Subsidiary. Notwithstanding the
foregoing, any Principal Subsidiary Bank may be merged into or consolidated with
another banking institution organized under the laws of the United States, any
State thereof or the District of Columbia, if after giving effect to such merger
or consolidation, the Corporation or any Wholly-Owned Subsidiary owns at least
80 percent of the Voting Stock of such other banking institution then issued and
outstanding free and clear of any security interest and if, immediately after
giving effect thereto, no Event of Default, and no event which, after notice or
lapse of time or both, would become an Event of Default, shall have happened and
be continuing. (Sections 101 and 1008 of the Senior Indenture). A Principal
Subsidiary Bank is defined in the Senior Indenture to mean any Subsidiary which
is a Bank and has total assets equal to 30 percent or more of the consolidated
assets of the Corporation determined as of the date of the most recent audited
financial statements of such entities. At present, the only Principal Subsidiary
Bank is First Tennessee Bank National Association. Voting Stock is defined in
the Senior Indenture to mean stock of the class or classes having general voting
power under ordinary circumstances to elect at least a majority of the board of
directors, managers or trustees of such corporation (irrespective of whether or
not at the time stock of any other class or classes shall have contingent voting
rights).
 
     The Subordinated Indenture contains no such covenant and the foregoing
covenant is not a covenant for the benefit of any series of Subordinated Debt
Securities. The Indenture relating to the Subordinated Capital Notes, however,
does contain a substantially identical covenant for the benefit of such
Subordinated Capital Notes.

DEFAULTS
 
  The Senior Indenture
 
     An Event of Default is defined in the Senior Indenture as, with respect to
Debt Securities of any series issued thereunder: (1) default in payment of
principal of or premium, if any, on any Debt Security of that series at
Maturity; (2) default for 30 days in payment of interest of any Debt Security of
that series; (3) default in the deposit of any sinking fund payment when due in
respect of that series; (4) default in the performance, or breach, of any other
covenant of the Corporation in the Senior Indenture or in the Debt Securities of
that series, continued for 30 days after written notice to the Corporation by
the Senior Trustee or to the Corporation and the Senior Trustee by the Holders
of not less than 25 percent of the aggregate principal amount of the Outstanding
Securities of that series; (5) failure to pay when due any indebtedness of the
Corporation or any Principal Subsidiary Bank for borrowed money in excess of
$5,000,000, or acceleration of the maturity of any such indebtedness in excess
of such amount if acceleration results from a default under the instrument
giving rise to such indebtedness and is not annulled within 30 days after due
notice, unless in either case such default is contested in good faith by
appropriate proceedings; (6) certain events of bankruptcy, insolvency or
reorganization of the Corporation, or any Principal Subsidiary Bank; and (7) any
other Event of Default with respect to Debt Securities of that series that is
specified in the applicable Prospectus Supplement. (Section 501 of the Senior
Indenture).
 
     The Senior Indenture provides that, if any Event of Default with respect to
Debt Securities of any series at the time outstanding thereunder occurs and is
continuing, either the Senior Trustee or the Holders of not less than 25 percent
in principal amount of the Outstanding Securities of that series may declare the
principal amount (or, if the Debt Securities of that series are Original Issue
Discount Securities, such portion of the principal amount as may be specified in
the terms of that series) of all Debt Securities of that series to be due and
payable immediately (provided that no such declaration is required upon certain
events of bankruptcy). The Holders of a majority in aggregate principal amount
of the Outstanding Securities of that series may annul a declaration of
acceleration of the Securities of such series, but only if all Events of Default
have been remedied on all payments due on the Debt Securities of that series
(other than those due as a result of acceleration) have been made and certain
other conditions have been met. (Section 502 of the Senior Indenture). Subject
to the duty of the Senior Trustee upon the occurrence and continuation of an
Event of Default to act with the required standard of care, the Senior Trustee
will be under no obligation to exercise any of its rights or powers under the
Senior Indenture at the request or direction of any of the Holders, unless such
Holders shall have offered to the Senior Trustee reasonable indemnity. (Section
603 of the Senior Indenture). The Holders of a majority in aggregate principal
amount of the Outstanding Securities of that series will have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Senior Trustee or exercising any trust or power conferred on
the Senior Trustee. (Section 512 of the Senior Indenture). The Holders of a
majority in aggregate principal amount of the Outstanding Securities of that
series may waive any past default under the Senior Indenture with respect to
such series, except a default in the payment of principal or interest or a
default in respect of each covenant in the Senior Indenture which cannot be
modified without the consent of the Holder of each Outstanding Security of the
series affected. (Section 513 of the Senior Indenture). See the second paragraph
under "Modification and Waiver" below. In the event of the bankruptcy,
insolvency or reorganization of the Corporation, the claims of Holders would be
subject as to enforcement to the broad equity power of a Federal Bankruptcy
Court, and to the determination by that court of the nature of the rights of the
Holders.
 
     The Senior Indenture contains a provision entitling the Senior Trustee,
subject to the duty of the Senior Trustee upon the occurrence and continuation
of an Event of Default to act with the required standard of care, to be
indemnified by the Holders of any series of Outstanding Securities thereunder
before proceeding to exercise any right or power under the Indenture at the
request of the Holders of such series of Securities. (Section 603 of the Senior
Indenture). The Senior Indenture provides that the Holders of a majority in
principal amount of Outstanding Securities thereunder of any series may direct
the time, method and place of conducting any proceeding for any remedy available
to the Senior Trustee, or exercising any trust or other power conferred on the
Senior Trustee, with respect to the Debt Securities of such series, provided
that the Senior Trustee may decline to act if such direction is contrary to law
or the Senior Indenture. (Section 512 of the Senior Indenture).
 
                                       16
<PAGE>   18
 
     The Corporation will file annually with the Senior Trustee a certificate as
to compliance with all conditions and covenants in the Senior Indenture.
(Section 1004 of the Senior Indenture).
 
  The Subordinated Indenture
 
     Payment of principal of the Subordinated Debt Securities may be accelerated
only upon an Event of Default (as defined below). There is no right of
acceleration in the case of a default in the payment of interest or the payment
of principal prior to the date of maturity or a default in the performance of
any other covenant of the Corporation in the Subordinated Indenture, unless the
terms of a particular series of Subordinated Debt Securities specifically
provide otherwise, in which case any such extension of such right of
acceleration will be described in the applicable Prospectus Supplement.
 
     An Event of Default is defined in the Subordinated Indenture as certain
events involving the bankruptcy, insolvency or reorganization of the Corporation
and any other Event of Default which may be provided for with respect to the
Subordinated Debt Securities of that series. (Section 501 of the Subordinated
Indenture). A Default, with respect to Debt Securities of that series, is
defined in the Subordinated Indenture to include: (1) any Event of Default with
respect to any Debt Securities of that series; (2) a default in the payment of
principal or premium, if any, of any Debt Security of that series at its
Maturity; (3) default in the payment of any interest on any Debt Security of
that series when due, continued for 30 days; (4) default in the making of any
sinking fund payment; (5) default in the performance, or breach, of any other
covenant or warranty of the Corporation in the Subordinated Indenture or in the
Debt Securities of that series, continued for 30 days after written notice to
the Corporation by the Subordinated Trustee or to the Corporation and the
Subordinated Trustee by the Holders of not less than 25 percent in aggregate
principal amount of the Outstanding Securities of such series; or (v) any other
Default with respect to Debt Securities of that series that is specified in the
applicable Prospectus Supplement. (Section 503 of the Subordinated Indenture).
If an Event of Default with respect to the Subordinated Debt Securities of any
series occurs and is continuing, either the Subordinated Trustee or the Holders
of not less than 25 percent in aggregate principal amount of the Outstanding
Securities of that series may accelerate the maturity of all Outstanding
Securities of such series. The Holders of a majority in aggregate principal
amount of the Outstanding Securities of that series may annul a declaration of
acceleration of the Securities of such series, but only if all Events of Default
have been remedied and all payments due on the Debt Securities of that series
(other than those due as a result of acceleration) have been made and certain
other conditions have been met. (Section 502 of the Subordinated Indenture).
Subject to the duty of the Subordinated Trustee upon the occurrence and
continuation of a Default to act with the required standard of care, the
Subordinated Trustee will be under no obligation to exercise any of its rights
or powers under the Subordinated Indenture at the request or direction of any of
the Holders, unless such Holders shall have offered to the Subordinated Trustee
reasonable indemnity. (Section 603 of the Subordinated Indenture). The Holders
of a majority in aggregate principal amount of the Outstanding Securities of
that series will have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Subordinated Trustee
or exercising any trust or power conferred on the Subordinated Trustee. (Section
512 of the Subordinated Indenture). The Holders of a majority in aggregate
principal amount of the Outstanding Securities of that series may waive any past
default under the Subordinated Indenture with respect to such series, except a
default in the payment of principal or interest or a default in respect of a
covenant in the Subordinated Indenture which cannot be modified without the
consent of the Holder of each Outstanding Security of the series affected.
(Section 513 of the Subordinated Indenture). See the second paragraph under
"Modification and Waiver" below.
 
     In the event of the bankruptcy, insolvency or reorganization of the
Corporation, the claims of the Holders would be subject as to enforcement to the
broad equity power of a Federal Bankruptcy Court, and to the determination by
that court of the nature of the rights of the Holders.
 
     The Corporation will file annually with the Subordinated Trustee a
certificate as to compliance with all conditions and covenants in the
Subordinated Indenture. (Section 1004 of the Subordinated Indenture).

<PAGE>   19
 
DEFEASANCE AND DISCHARGE
 
     Each Indenture provides that the terms of any series of Debt Securities
issued thereunder may provide that the Corporation may terminate all or certain
of its obligations under such Indenture with respect to the Debt Securities of
such series on the terms and subject to the conditions contained in the
Applicable Indenture, by (a) depositing irrevocably with the Applicable Trustee
as trust funds in trust (1) in the case of Debt Securities denominated in a
foreign currency, money in such foreign currency or Foreign Government
Obligations (as defined below) of the foreign government or governments issuing
such foreign currency, (2) in the case of Debt Securities denominated in U.S.
dollars, U.S. dollars or U.S. Government Obligations (as defined below), in each
case in an amount which through the payment of interest, principal or premium,
if any, in respect thereof in accordance with their terms will provide (without
any reinvestment of such interest, principal or premium), not later than one
business day before the due date of any payment, money, or (3) a combination of
money and U.S. Government Obligations (as hereinafter defined) or Foreign
Government Obligations, as applicable, sufficient to pay the principal of or
premium, if any, and interest on, the Debt Securities of such series as such are
due and (b) satisfying certain other conditions precedent specified in the
Applicable Indenture. Such deposit and termination is conditioned, among other
things, upon the Corporation's delivery of (a) an opinion of independent counsel
that the Holders of the Debt Securities of such series will have no federal
income tax consequences as a result of such deposit and termination and (b) if
the Debt Securities of such series are then listed on the New York Stock
Exchange, an opinion of counsel that the Debt Securities of such series will not
be delisted as a result of the exercise of this option. (Article Thirteen).
 
     "U.S. Government Obligations" means securities that are (1) direct
obligations of the United States of America for the payment of which its full
faith and credit is pledged or (2) obligations of a Person controlled or
supervised by and acting as an agency or instrumentality of the United States of
America the payment of which is unconditionally guaranteed as a full faith and
credit obligation by the United States of America, which, in either case, under
clauses (1) or (2) are not callable or redeemable at the option of the issuer
thereof. "Foreign Government Obligations" means securities denominated in a
Foreign Currency that are (1) direct obligations of a foreign government for the
payment of which its full faith and credit is pledged or (2) obligations of a
Person controlled or supervised by and acting as an agency or instrumentality of
a foreign government the payment of which is unconditionally guaranteed as a
full faith and credit obligation by such foreign government, which, in either
case, under clauses (1) or (2) are not callable or redeemable at the option of
the issuer thereof. (Section 101).
 
     The applicable Prospectus Supplement will state whether any defeasance
provisions of the Applicable Indenture will apply to Offered Debt Securities.
 
MODIFICATION AND WAIVER
 
     Certain modifications and amendments of each of the Indentures may be made
by the Corporation and the Trustee under the Applicable Indenture only with the
consent of the Holders of not less than a majority in aggregate principal amount
of the Outstanding Securities of each series issued under such Indenture and
affected by the modification or amendment, provided that no such modification or
amendment may, without the consent of the Holder of each Outstanding Security
issued under such Indenture and affected thereby: (1) change the Stated Maturity
of the principal of, or any installment of principal of or interest on, any such
Debt Security; (2) reduce the principal amount of, or the premium, if any, or
the interest on, any such Debt Security (including in the case of an Original
Issue Discount Security the amount payable upon acceleration of the maturity
thereof); (3) change the place of payment where, or the coin or currency or
currency unit in which, any principal of, or premium, if any, or interest on,
any such Debt Security is payable; (4) impair the right to institute suit for
the enforcement of any such payment on or after the Stated Maturity thereof (or,
in the case of redemption, on or after the Redemption Date); (5) reduce the
above-stated percentage of Outstanding Securities of any series the consent of
the Holders of which is necessary to modify or amend the Applicable Indenture;
or (6) modify the foregoing requirements or reduce the percentage of aggregate
principal amount of Outstanding Securities of any series required to be held by
Holders seeking to waive compliance with certain provisions of the Applicable
Indenture or seeking to waive certain defaults. (Section 902).

     The Holders of not less than a majority in aggregate principal amount of
the Outstanding Securities of any series may on behalf of the Holders of all
Debt Securities of that series waive, insofar as that series is concerned,
compliance by the Corporation with certain restrictive provisions of the
Applicable Indenture. (Section 1008 of the Subordinated Indenture, Section 1009
of the Senior Indenture). The Holders of not less than a majority in aggregate
principal amount of the Outstanding Securities of any series may on behalf of
the Holders of all Debt Securities of that series waive any past default under
the Applicable Indenture with respect to that series, except a default in the
payment of the principal of, or premium, if any, or interest on any Debt
Security of that series or in respect of a covenant or provision which under the
Applicable Indenture cannot be modified or amended without the consent of the
Holder of each Outstanding Security issued thereunder of the series affected.
(Section 513).
 
     Each of the Senior Indenture and the Subordinated Indenture may be modified
or amended by the Corporation and the Trustee under the Applicable Indenture
without the consent of Holders of the Outstanding Securities issued under such
Indenture for the following purposes: (i) to evidence the succession of another
Person to the Corporation and the assumption by such successor of the covenants
of the Corporation, (ii) to add to the covenants of the Corporation or to
surrender any of its rights or powers, (iii) to add any Defaults or Events of
Default, (iv) to add to or change the provisions of the Applicable Indenture to
facilitate the issuance of Debt Securities in bearer or uncertificated form, (v)
to modify the Applicable Indenture provided that such modification (A) will not
apply to any Debt Securities of any series created prior to such modification or
modify the rights of any holder of such Security and (B) will become effective
only when there is no such Security Outstanding, (vi) to secure the Securities,
(vii) to establish the form and terms of Securities of any series in accordance
with the Applicable Indenture, (viii) to evidence the acceptance of an
appointment by a successor Trustee with respect to Debt Securities of one or
more series or to add to or change any provisions of the Indentures to provide
for or facilitate the administration of the trusts thereunder by more than one
trustee, or (ix) to make provision for conversion rights or (x) to cure any
ambiguity, corrector supplement any defective or inconsistent provision or make
other provisions with respect to matters arising under the Indentures which do
not adversely affect the interests of the Holders of Debt Securities or any
Series in any material respect. (Section 901).
 
     Each Indenture provides that in determining whether the Holders of the
requisite principal amount of the Outstanding Securities issued under such
Indenture have given any request, demand, authorization, direction, notice,
consent or waiver thereunder or are present at a meeting of Holders of Debt
Securities for quorum purposes, (1) the principal amount of an Original Issue
Discount Security that shall be deemed to be Outstanding shall be the amount of
the principal thereof that would be due and payable as of the date of such
determination upon acceleration of the Maturity thereof, and (2) the principal
amount of a Debt Security denominated in a foreign currency or currency unit
shall be the U.S. dollar equivalent, determined on the date of original issuance
of such Debt Security, of the principal amount of such Debt Security or, in the
case of an Original Issue Discount Security, the U.S. dollar equivalent,
determined on the date of original issuance of such Debt Security, of the amount
determined as provided in (1) above. (Section 101).
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
     The Indentures each provide that the Corporation may not consolidate with
or merge into any other Person or transfer its properties and assets
substantially as an entirety to any Person unless (1) the Person formed by such
consolidation or into which the Corporation is merged or the Person to which the
properties and assets of the Corporation are so transferred shall be a
corporation or partnership organized and validly existing under the laws of the
United States, any State thereof or the District of Columbia and shall expressly
assume by a supplemental indenture the payment of the principal of and premium,
if any, and interest on the Senior Debt Securities or the Subordinated Debt
Securities, as the case may be, and the performance of the other covenants of
the Corporation under the Applicable Indenture; (2) immediately after giving
effect to such transaction, no Event of Default or Default, as applicable, and
no event which, after notice or lapse of time or both, would become an Event of
Default or Default, as applicable, shall have occurred and be continuing; and
(3) certain other conditions are met. (Section 801).
 
                                       19

TRUSTEES
 
     Any Trustee may resign or be removed with respect to one or more series of
Debt Securities and a successor Trustee may be appointed to act with respect to
such series. (Section 610). In the event that two or more persons are acting as
Trustee with respect to different series of Debt Securities, each such Trustee
shall be a Trustee of a trust under the related Indenture separate and apart
from the trust administered by any other such Trustee (Section 611), and any
action described herein to be taken by the "Trustee" may then be taken by each
such Trustee with respect to, and only with respect to, the one or more series
of Debt Securities for which it is Trustee.
 
     In the normal course of business, the Corporation and its subsidiaries may
conduct banking transactions with any Trustee, and any Trustee may conduct
banking transactions with the Corporation and its subsidiaries.
 
     The First National Bank of Chicago will be the Subordinated Trustee under
the Subordinated Indenture, unless otherwise specified with respect to any
series of Offered Debt Securities in the applicable Prospectus Supplement.
 
GOVERNING LAW
 
     The Indentures and the Debt Securities will be governed by, and construed
in accordance with, the laws of the State of New York.
 
                          DESCRIPTION OF CAPITAL STOCK
 
     The Corporation's Restated Charter, as amended (the "Charter") authorizes
the issuance of up to 50,000,000 shares of Common Stock and 5,000,000 shares of
Preferred Stock. The Corporation intends to propose for shareholder approval at
the annual shareholders' meeting in April 1994 an amendment to the Charter to
increase the number of authorized shares of Common Stock from 50,000,000 to
100,000,000. As of February 23, 1994, 30,175,456 shares of Common Stock and no
shares of Preferred Stock were issued and outstanding, approximately 3.3 million
shares of Common Stock were reserved for issuance under various employee stock
plans and the Corporation's dividend reinvestment plan, and approximately 1.6
million shares were reserved for issuance in connection with pending
acquisitions anticipated to close in the first quarter of 1994. In addition,
30,175 shares of Preferred Stock are reserved for issuance under the Rights Plan
(defined below). The Common Stock of the Corporation is quoted through the
NASDAQ National Market System under the symbol "FTEN."
 
DESCRIPTION OF PREFERRED STOCK
 
     The following is a description of certain general terms and provisions of
the Preferred Stock. The particular terms of any series of Preferred Stock will
be described in the applicable Prospectus Supplement. If so indicated in a
Prospectus Supplement, the terms of any such series may differ from the terms
set forth below.
 
     The summary of terms of the Corporation's Preferred Stock contained in this
Prospectus does not purport to be complete and is subject to, and qualified in
its entirety by, the provisions of the Charter and the Articles of Amendment
relating to each series of the Preferred Stock (the "Articles of Amendment"),
which will be filed as an exhibit to or incorporated by reference in the
Registration Statement of which this Prospectus is a part at or prior to the
time of issuance of such series of the Preferred Stock.
 
     Under the Charter, the Corporation's Preferred Stock may be issued from
time to time in one or more series, without shareholder approval, when
authorized by the Board of Directors. Subject to limitations prescribed by law,
the Board of Directors is authorized to determine the voting powers (if any),
designation, preferences and relative, participating, optional or other special
rights, and the qualifications, limitations or restrictions thereof, for each
series of Preferred Stock that may be issued, and to fix the number of shares of
each such series. Thus, the Board of Directors, without shareholder approval,
could authorize the issuance of Preferred Stock with voting, conversion and
other rights that could adversely affect the voting power and other rights of
holders of Common Stock or other series of Preferred Stock.
 
                                       20
<PAGE>   22
 
     The Preferred Stock shall have the dividend, liquidation, redemption and
voting rights set forth below unless otherwise described in a Prospectus
Supplement relating to a particular series of the Preferred Stock. The
applicable Prospectus Supplement will describe the following terms of the series
of Preferred Stock in respect of which this Prospectus is being delivered: (1)
the title of such Preferred Stock and the number of shares offered; (2) the
amount of liquidation preference per share; (3) the initial public offering
price at which such Preferred Stock will be issued; (4) the dividend rate (or
method of calculation), the dates on which dividends shall be payable and the
dates from which dividends shall commence to cumulate, if any; (5) any
redemption or sinking fund provisions; (6) any conversion or exchange rights;
(7) any additional voting, dividend, liquidation, redemption, sinking fund and
other rights, preferences, privileges, limitations and restrictions; (8) any
listing of such Preferred Stock on any securities exchange; and (9) the relative
ranking and preferences of such Preferred Stock as to dividend rights and rights
upon liquidation, dissolution or winding up of the affairs of the Corporation.
 
  General
 
     The Preferred Stock offered hereby will be issued in one or more series.
Shares of Preferred Stock, upon issuance against full payment of the purchase
price therefor, will be fully paid and nonassessable. Neither the par value nor
the liquidation preference is indicative of the price at which the Preferred
Stock will actually trade on or after the date of issuance.
 
  Rank
 
     The Preferred Stock shall, with respect to dividend rights and rights upon
liquidation, winding up and dissolution of the Corporation, rank prior to the
Corporation's Common Stock and to all other classes and series of equity
securities of the Corporation now or hereafter authorized, issued or outstanding
(the Common Stock and such other classes and series of equity securities
collectively may be referred to herein as the "Junior Stock"), other than any
classes or series of equity securities of the Corporation which by their terms
specifically provide for a ranking on a parity with (the "Parity Stock") or
senior to (the "Senior Stock") the Preferred Stock as to dividend rights and
rights upon liquidation, winding up or dissolution of the Corporation. The
Preferred Stock shall be junior to all outstanding debt of the Corporation. The
Preferred Stock shall be subject to creation of Senior Stock, Parity Stock and
Junior Stock to the extent not expressly prohibited by the Corporation's
Charter. Unless otherwise specified in the applicable Prospectus Supplement, the
Preferred Stock shall rank on a parity with all other preferred stock of the
Corporation and with each other series of Preferred Stock.
 
  Dividends
 
     Holders of Preferred Stock shall be entitled to receive, when, as and if
declared by the Board of Directors out of funds of the Corporation legally
available for payment, cash dividends, payable at such dates and at such rates
per share per annum as described in the applicable Prospectus Supplement. Such
rate may be fixed or variable or both. Each declared dividend shall be payable
to holders of record as they appear at the close of business on the stock books
of the Corporation on such record dates, not more than 60 calendar days
preceding the payment dates therefor, as are determined by the Board of
Directors (each of such dates, a "Record Date").
 
     Such dividends may be cumulative or noncumulative, as described in the
applicable Prospectus Supplement. If dividends on a series of Preferred Stock
are noncumulative and if the Board of Directors fails to declare a dividend in
respect of a dividend period with respect to such series, then holders of such
Preferred Stock will have no right to receive a dividend in respect of such
dividend period, and the Corporation will have no obligation to pay the dividend
for such period, whether or not dividends are declared payable on any future
dividend payment dates. If dividends of a series of Preferred Stock are
cumulative, the dividends on such shares will accrue from and after the date set
forth in the applicable Prospectus Supplement.
 
     No full dividends shall be declared or paid or set apart for payment on
preferred stock of the Corporation of any series ranking, as to dividends, on a
parity with or junior to the series of Preferred Stock offered by the
 
                                       21
<PAGE>   23
 
applicable Prospectus Supplement for any period unless full dividends for the
immediately preceding dividend period on such Preferred Stock (including any
accumulation in respect of unpaid dividends for prior dividend periods, if
dividends on such Preferred Stock are cumulative) have been or contemporaneously
are declared and paid or declared and a sum sufficient for the payment thereof
is set apart for such payment. When dividends are not so paid in full (or a sum
sufficient for such full payment is not so set apart) upon such Preferred Stock
and any other preferred stock of the Corporation ranking on a parity as to
dividends with the Preferred Stock, dividends upon such Preferred Stock and
dividends on such other preferred stock ranking on a parity with the Preferred
Stock shall be declared pro rata so that the amount of dividends declared per
share on such Preferred Stock and such other preferred stock ranking on a parity
with the Preferred Stock shall in all cases bear to each other the same ratio
that accrued dividends for the then-current dividend period per share on such
Preferred Stock (including any accumulation in respect of unpaid dividends for
prior dividend periods, if dividends on such Preferred Stock are cumulative) and
accrued dividends, including required or permitted accumulations, if any, on
shares of such other preferred stock, bear to each other. No interest, or sum of
money in lieu of interest, shall be payable in respect of any dividend
payment(s) on Preferred Stock which may be in arrears. Unless full dividends on
the series of Preferred Stock offered by the applicable Prospectus Supplement
have been declared and paid or set apart for payment for the immediately
preceding dividend period (including any accumulation in respect of unpaid
dividends for prior dividend periods, if dividends on such Preferred Stock are
cumulative), (a) no cash dividend or distribution (other than in shares of
Junior Stock) may be declared, set aside or paid on the Junior Stock, (b) the
Corporation may not, directly or indirectly, repurchase, redeem or otherwise
acquire any shares of its Junior Stock (or pay any monies into a sinking fund
for the redemption of any shares) except by conversion into or exchange for
Junior Stock, and (c) the Corporation may not, directly or indirectly,
repurchase, redeem or otherwise acquire any Preferred Stock ranking on parity as
to dividends (or pay any monies into a sinking fund for the redemption of any
shares of any such stock) otherwise than pursuant to pro rata offers to purchase
or a concurrent redemption of all, or a pro rata portion, of the outstanding
Preferred Stock and ranking on parity as to dividends (except by conversion into
or exchange for Junior Stock).
 
     Any dividend payment made on a series of Preferred Stock shall first be
credited against the earliest accrued but unpaid dividend due with respect to
shares of such series which remains payable.
 
  Redemption
 
     The terms, if any, on which Preferred Stock of any series may be redeemed
will be set forth in the applicable Prospectus Supplement.
 
  Liquidation
 
     In the event of a voluntary or involuntary liquidation, dissolution or
winding up of the affairs of the Corporation, the holders of a series of
Preferred Stock will be entitled, subject to the rights of creditors, but before
any distribution or payment to the holders of Common Stock or any other security
ranking junior to the Preferred Stock on liquidation, dissolution or winding up
of the Corporation, to receive a liquidating distribution in the amount of the
liquidation preference per share as set forth in the applicable Prospectus
Supplement plus accrued and unpaid dividends for the then-current dividend
period (including any accumulation in respect of unpaid dividends for prior
dividend periods, if dividends on such series of Preferred Stock are
cumulative). If the amounts available for distribution with respect to the
Preferred Stock, and all other outstanding stock of the Corporation ranking on a
parity with the Preferred Stock upon liquidation, dissolution or winding up are
not sufficient to satisfy the full liquidation rights of all the outstanding
Preferred Stock and stock ranking on a parity therewith upon liquidation,
dissolution or winding up, then the holders of each series of such stock will
share ratably in any such distribution of assets in proportion to the full
respective preferential amount (which in the case of preferred stock may include
accumulated dividends) to which they are entitled. After payment of the full
amount of the liquidation preference, the holders of Preferred Stock will not be
entitled to any further participation in any distribution of assets by the
Corporation.

  Voting
 
     The terms, if any, on which Preferred Stock of any series may be entitled
to vote will be set forth in the applicable Prospectus Supplement.
 
  Conversion
 
     The terms, if any, on which Preferred Stock of any series may be converted
into another class or series of securities of the Corporation will be set forth
in the applicable Prospectus Supplement.
 
  No Other Rights
 
     The shares of a series of Preferred Stock will not have any preferences,
voting powers or relative, participating, optional or other special rights
except as set forth above or in the applicable Prospectus Supplement, the
Charter and in the applicable Articles of Amendment or as otherwise required by
law.
 
  Transfer Agent and Registrar
 
     The transfer agent for each series of Preferred Stock will be described in
the related Prospectus Supplement.
 
DESCRIPTION OF COMMON STOCK
 
     The following summary of the terms and provisions of the Common Stock does
not purport to be complete and is qualified in its entirety by reference to the
Charter, which is filed as an exhibit to the Registration Statement of which
this Prospectus is a part.
 
     The holders of Common Stock are entitled to receive, ratably, such
dividends as may be declared by the Board of Directors of the Corporation from
funds legally available therefor, provided that if any shares of Preferred Stock
are at the time outstanding, the payment of dividends on Common Stock or other
distributions (including purchases of Common Stock) may be subject to the
declaration and payment of full cumulative dividends, and the absence of
arrearages in any mandatory sinking fund, on outstanding shares of Preferred
Stock. The Board of Directors of the Corporation currently intends to maintain
its present policy of paying regular quarterly cash dividends; however, the
declaration and amount of future dividends will depend on circumstances existing
at the time, including the Corporation's earnings, financial condition and
capital requirements. See "Supervision and Regulation."
 
     The holders of outstanding shares of Common Stock are entitled to one vote
for each share on all matters presented to shareholders, including elections of
directors. There is no cumulative voting in the election of directors, which
means that the holders of a majority of the outstanding Common Stock can elect
all of the directors then standing for election. The holders of Common Stock do
not have any conversion, redemption or preemptive rights to subscribe to any
securities of the Corporation. Upon any dissolution, liquidation or winding up
of the Corporation resulting in a distribution of assets to the shareholders,
the number of shares of Common Stock are entitled to receive such assets ratably
according to their respective number of shares after payment of all liabilities
and obligations and satisfaction of the liquidation preferences of any shares of
Preferred Stock at the time outstanding.
 
     The Corporation's Board of Directors is divided into three classes, which
results in approximately one-third of the directors being elected each year. In
addition, the Charter and the Corporation's bylaws, among other things,
generally give to the Board the authority to fix the number of directors and to
remove directors from and fill vacancies on the Board, other than removal for
cause and the filling of vacancies created thereby which are reserved to
shareholders exercising at least a majority of the voting power of all
outstanding voting stock of the Corporation. To change these provisions of the
bylaws, other than by action of the Board, and to amend these provisions of the
Charter or to adopt any provision of the Charter inconsistent with such bylaw
provisions, would require approval by the holders of at least 80% of the voting
power of all outstanding voting stock. Such classification of the Board and such
other provisions of the Charter and the bylaws may have a
 
                                       23
<PAGE>   25
 
significant effect on the ability of the shareholders of the Board to change the
composition of an incumbent Board or to benefit from certain transactions which
are opposed by the Board.
 
     Under the Corporation's Shareholder Protection Rights Agreement, dated as
of September 7, 1989 (the "Rights Plan"), each share of Common Stock has, and
each share of Common Stock offered hereby will have, attached to it a Right to
purchase 1/100th of a share of Participating Preferred Stock, without par value,
for $76.67 (the "Exercise Price"), subject to adjustment, upon the business day
following the earlier of (i) the 10th day after commencement of a tender or
exchange offer which, if consummated, would result in a person becoming the
beneficial owner of 10% or more of the outstanding shares of Common Stock (an
"Acquiring Person") and (ii) the first date (the "Flip-in Date") of public
announcement that a person has become an Acquiring Person. The Rights will
expire on the earliest of (i) the Exchange Time (defined below), (ii) September
18, 1999 and (iii) the date on which the Rights are redeemed as described below.
The Board of Directors may, at its option, at any time prior to the Flip-in
Date, redeem all the Rights at a price of $.01 per Right. If a Flip-in Date
occurs, each Right (other than Rights beneficially owned by the Acquiring Person
or its affiliates, associates or transferees, which Rights will become void), to
the extent permitted by applicable law, will constitute the right to purchase
shares of Common Stock or Participating Preferred Stock having an aggregate
market price equal to twice the Exercise Price for an amount in cash equal to
the then-current Exercise Price. In addition, the Board of Directors may, at its
option, at any time after a Flip-in Date and prior to the time that an Acquiring
Person becomes the beneficial owner of more than 50% of the outstanding shares
of Common Stock, elect to exchange the Rights (other than Rights beneficially
owned by the Acquiring Person) for shares of Common Stock or Participating
Preferred Stock at an exchange ratio of one share of Common Stock or 1/100th of
a share of Participating Preferred Stock per Right (the "Exchange Right"). The
Corporation may not agree to be acquired by an Acquiring Person without
providing that each Right, upon such acquisition, will constitute the right to
purchase common stock of the Acquiring Person having an aggregate market price
equal to twice the Exercise Price for an amount in cash equal to the
then-current Exercise Price. The Rights will not prevent a takeover of the
Corporation. The Rights, however, may have certain anti-takeover effects. The
Rights may cause substantial dilution to an Acquiring Person unless the Rights
are first redeemed by the Board of Directors.
 
     The Common Stock shall have equal dividend, distribution, liquidation and
other rights, and shall have no preference, appraisal or exchange rights. All
outstanding shares of Common Stock are, and the shares offered hereby, upon
issuance, will be, fully paid and non-assessable.
 
     The transfer agent for the Common Stock is The First National Bank of
Boston.
 
                        DESCRIPTION OF DEPOSITARY SHARES
 
     The description set forth below and in any Prospectus Supplement of certain
provisions of the Deposit Agreement and of the Depositary Shares and Depositary
Receipt (each as defined below) does not purport to be complete and is subject
to and qualified in its entirety by reference to the forms of Deposit Agreement
and Depositary Receipts relating to each series of the Preferred Stock which
have been or will be filed with the Commission at or prior to the time of the
offering of such series of the Preferred Stock.
 
GENERAL
 
     The Corporation may, at its option, elect to offer fractional interests in
shares of Preferred Stock ("Depositary Shares"), rather than shares of Preferred
Stock. In the event such option is exercised, the Corporation will provide for
the issuance by a Depositary to the public of receipts for Depositary Shares
("Depositary Receipts"), each of which will represent a fractional interest (to
be set forth in the Prospectus Supplement relating to a particular series of
Preferred Stock which will be filed with the Commission at or prior to the time
of offering such series of the Preferred Stock as described below) of a share of
Preferred Stock.
 
     The shares of any series of the Preferred Stock underlying the Depositary
Shares will be deposited under a separate Deposit Agreement (the "Deposit
Agreement") each between the Corporation and a bank or trust
 
                                       24
<PAGE>   26
 
company selected by the Corporation having its principal office in the United
States and having a combined capital and surplus of at least $50,000,000 (the
"Depositary"). The Prospectus Supplement relating to a series of Depositary
Shares will set forth the name and address of the Depositary. Subject to the
terms of the applicable Deposit Agreement, each owner of a Depositary Share will
be entitled, in proportion to the applicable fractional interest in a share of
Preferred Stock underlying such Depositary Shares, to all the rights and
preferences of the Preferred Stock underlying such Depositary Share (including
dividend, voting, redemption, conversion and liquidation rights).
 
     The Depositary Shares will be evidenced by Depositary Receipts issued
pursuant to the Deposit Agreement.
 
     Pending the preparation of definitive engraved Depositary Receipts, the
Depositary may, upon the written order of the Corporation, 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 Corporation's expense.
 
     Upon surrender of Depositary Receipts at the office of the Depositary and
upon payment of the charges provided in the Deposit Agreement and subject to the
terms thereof, a holder of Depositary Shares is entitled to have the Depositary
deliver to such holder the whole shares of Preferred Stock underlying the
Depositary Shares evidenced by the surrendered Depositary Receipts. No
fractional shares of such Preferred Stock shall be delivered.
 
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 on the relevant record
date. The Depositary 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 Corporation, sell such property and distribute the net proceeds from such
sale to such holders.
 
     The Deposit Agreement will also contain provisions relating to the manner
in which any subscription or similar rights offered by the Corporation to
holders of the Preferred Stock shall be made available to holders of Depositary
Shares.
 
REDEMPTION OF DEPOSITARY SHARES
 
     If the series of Preferred Stock represented by the applicable series of
Depositary Shares is redeemable, such Depositary Shares will be redeemable from
the proceeds received by the Depositary resulting from the redemption, in whole
or in part, of such Preferred Stock. Whenever the Corporation redeems any
Preferred Stock held by the Depositary, the Depositary will redeem as of the
same redemption date the number of Depositary Shares representing the Preferred
Stock so redeemed.
 
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 number of shares of Preferred Stock
underlying such holder's Depositary Shares. The Depositary will endeavor,
insofar as practicable, to vote the
 
                                       25
<PAGE>   27
 
number of shares of Preferred Stock underlying such Depositary Shares in
accordance with such instructions, and the Corporation will agree to take all
action which may be deemed necessary by the Depositary in order to enable the
Depositary to do so. To the extent the Depositary does not receive specific
instructions from the holders of Depositary Shares relating to such Preferred
Stock, it will abstain from voting the related shares of Preferred Stock unless
otherwise indicated in the Prospectus Supplement.
 
AMENDMENT AND TERMINATION OF 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 Corporation and the Depositary. However, any amendment which
materially and adversely alters the rights of the existing holders of Depositary
Shares will not be effective unless such amendment has been approved by the
record holders of at least a majority of the Depositary Shares issued under such
Depositary Agreement then outstanding. A Deposit Agreement may be terminated by
the Corporation or the Depositary only if (i) all outstanding Depositary Shares
relating thereto have been redeemed or (ii) there has been a final distribution
in respect of the Preferred Stock of the relevant series in connection with any
liquidation, dissolution or winding up of the Corporation and such distribution
has been distributed to the holders of the related Depositary Shares.
 
CHARGES OF DEPOSITARY
 
     The Corporation will pay all transfer and other taxes and governmental
charges arising solely from the existence of the depositary arrangements. The
Corporation 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 Shares 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 Corporation is required to furnish to the holders of the Preferred
Stock.
 
     Neither the Depositary nor the Corporation 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 Corporation
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 Shares 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 Corporation
notice of its election to do so, and the Corporation may at any time remove the
Depositary, and such resignation or removal will 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.
 
                              PLAN OF DISTRIBUTION
 
     The Corporation may sell the Securities to one or more underwriters for
public offering and sale by them or may sell the Securities to investors
directly or through agents. The applicable Prospectus Supplement will set forth
the terms of the offering of the Securities offered thereby, including the names
of any underwriters,
 
                                       26
<PAGE>   28
 
agents or dealers, the purchase price of such Securities and the proceeds to the
Corporation from any sale, any underwriting discounts and other items
constituting underwriters' compensation and any discounts and commissions
allowed or reallowed or paid to dealers or agents. The Corporation has reserved
the right to sell the Securities directly to investors on its own behalf in
those jurisdictions where it is authorized to do so.
 
     Underwriters may offer and sell the Securities at a fixed price or prices
that may be changed, at market prices prevailing at the time of sale, at prices
related to such prevailing market prices or at negotiated prices. The
Corporation also may, from time to time, authorize dealers, acting as the
Corporation's agents, to offer and sell the Securities upon such terms and
conditions as set forth in the related Prospectus Supplement. In connection with
the sale of the Securities, underwriters may receive compensation from the
Corporation in the form of underwriting discounts or commissions and may also
receive commissions from purchasers of the Securities for whom they may act as
agent. Underwriters may sell the Securities to or through dealers, and such
dealers may receive compensation in the form of discounts, concession or
commissions from the underwriters and/or commissions from the purchasers for
whom they may act as agents.
 
     Any underwriting compensation paid by the Corporation to underwriters or
agents in connection with the offering of the Securities, and any discounts,
concessions or commissions allowed by underwriters to participating dealers,
will be set forth in the related Prospectus Supplement. Dealers and agents
participating in the distribution of the Securities may be deemed to be
underwriters, and any discounts and commissions received by them and any profit
realized by them on resale of the Securities may be deemed to be underwriting
discounts and commissions. Underwriters, dealers and agents may be entitled,
under agreements entered into with the Corporation, to indemnification against
and contribution towards certain civil liabilities.
 
     If so indicated in the related Prospectus Supplement, the Corporation will
authorize dealers acting as the Corporation's agents to solicit agreements by
certain institutions to purchase Debt Securities from the Corporation at the
public offering price set forth in the related Prospectus Supplement pursuant to
delayed delivery contracts ("Contracts") providing for payment and delivery on
the date or dates stated in a Prospectus Supplement. Each Contract will be for
an amount not less than, and the aggregate amount of the Debt Securities based
on the liquidation value thereof, sold pursuant to Contracts will be not less
nor more than the respective amounts stated in a Prospectus Supplement.
Institutions, with whom Contracts, when authorized, may be made include
commercial and savings banks, insurance companies, pension funds, investment
companies, educational and charitable institutions and other institutions, but
will in all cases be subject to the approval of the Corporation. Contracts will
be subject to the condition that the purchase by an institution of the
Securities covered by Contracts will not at the time of delivery be prohibited
under the laws of any jurisdiction in the United States to which such
institution is subject.
 
     Any Securities issued hereunder (other than Common Stock) will be new
issues of securities with no established trading market. Any underwriters or
agents to or through whom such Securities are sold by the Corporation for public
offering and sale may make a market in such Securities, but such underwriters or
agents will not be obligated to do so and may discontinue any market at any time
without notice. No assurance can be given as to the liquidity of the trading
market for any such Securities.
 
     Certain of the underwriters, dealers or agents and their associates may be
customers of, engage in transactions with, and perform services for, the
Corporation and certain of its affiliates in the ordinary course of business.
Except as otherwise stated in the applicable Prospectus Supplement, any loans
and outstanding commitments to such underwriters, dealers or agents and their
associates will be made on terms, including interest rates and collateral, no
more favorable than those prevailing at the time for comparable transactions
with other persons and will not involve more than normal risk of collectibility.
 
                           VALIDITY OF THE SECURITIES
 
     The validity of the Securities will be passed upon for the Corporation by
Harry A. Johnson, III, Esq., Executive Vice President and General Counsel of the
Corporation, unless otherwise specified in the applicable Prospectus Supplement,
and for any underwriters by the counsel named in the applicable Prospectus

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Tennessee Code Annotated, Sections 48-1-406 through 48-1-411 authorizes a
corporation to provide for the indemnification of officers, directors, employees
and agents in terms sufficiently broad to permit indemnification under certain
circumstances for liabilities (including reimbursement for expenses incurred)
arising under the Securities Act of 1933, as amended. The Corporation has
adopted the provisions of the Tennessee statute pursuant to Article XXVIII of
its Bylaws. Also, the Corporation has a Directors' and Officers' Liability
Insurance Policy which provides coverage sufficiently broad to permit
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933,
as amended.
 
     Tennessee Code Annotated Section 48-12-102 permits the inclusion in the
charter of a Tennessee corporation of a provision, with certain exceptions,
eliminating the personal monetary liability of directors to the corporation or
its shareholders for breach of the duty of care. The Corporation has adopted the
provisions of the statute in Article 13 of its charter.
 
     The shareholders of the Corporation have approved an amendment to Article
XXVIII of the Bylaws pursuant to which the Corporation is required to indemnify
each director and any officers designated by the Corporation's Board of
Directors, and advance expenses, to the maximum extent not prohibited by law. In
accordance with the foregoing, the Board is authorized to enter into individual
indemnity agreements with the directors and such officers. Such indemnity
agreements have been approved for all of the directors and certain officers.
 
     Reference is also made to the Underwriting Agreements filed as Exhibits
hereto, for provisions regarding indemnification of the registrant's officers
and directors against certain liabilities.

ITEM 17.  UNDERTAKINGS.
 
     The undersigned registrant hereby undertakes:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:
 
             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;
 
             (ii) 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;
 
             (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;
 
                                      II-2
<PAGE>   32
 
provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
registration statement is on Form S-3 or Form S-8, 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 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.
 
     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     The undersigned registrant hereby undertakes to file an application for the
purpose of determining the eligibility of the trustee to act under subsection
(a) of section 310 of the Trust Indenture Act of 1939 in accordance with the
rules and regulations prescribed by the Commission under section 305(b)(2) of
the Trust Indenture Act of 1939.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described under Item 15 above, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted 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
Securities Act of 1933 and will be governed by the final adjudication of such
issue.

   amount has been theretofore deposited with the Trustee or any Paying Agent
   (other than the Company) in trust or set aside and segregated in trust by

                                     -4-
<PAGE>   13
   been duly given pursuant to this Indenture or provision therefor

   and delivered pursuant to this Indenture, other than any such Securities in
   respect of which there shall have been presented to the Trustee proof
   satisfactory to it that such Securities are held by a bona fide purchaser in
   whose hands such Securities are valid obligations of the Company;

provided, however, that in determining whether the Holders of the requisite
principal amount of the Outstanding Securities have given, made or taken any
request, demand, authorization, direction, notice, consent, waiver or other
action hereunder as of any date, (A) the principal amount of an Original Issue
Discount Security which shall be deemed to be Outstanding shall be the amount
of the principal thereof which would be due and payable as of such date upon
acceleration of the Maturity thereof to such date pursuant to Section 502, (B)
if, as of such date, the principal amount payable at the Stated Maturity of a
Security is not determinable, the principal amount of such Security which shall
be deemed to be Outstanding shall be the amount as specified or determined as
contemplated by Section 301, (C) the principal amount of a Security denominated
in one or more foreign currencies or currency units which shall be deemed to be
Outstanding shall be the U.S. dollar equivalent, determined as of such date in

owned by the Company or any other obligor upon the Securities or any Affiliate
of the Company or of such other obligor shall be disregarded and deemed not to
be Outstanding, except that, in determining whether the Trustee shall be
protected in relying upon any such request, demand, authorization, direction,
notice, consent, waiver or other action, only Securities which the Trustee
knows to be so owned shall be so disregarded. Securities so owned which have
been pledged in good faith may be regarded as Outstanding if the pledgee

other obligor upon the Securities or any Affiliate of the Company or of such
other obligor.

SECTION 104.  Acts of Holders; Record Dates.

      Any request, demand, authorization, direction, notice, consent, waiver or
other action provided or permitted by this Indenture to be given, made or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

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

      The ownership of Securities shall be proved by the Security Register.

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

      Without limiting the generality of the foregoing, a Holder, including a
Depositary that is a Holder of a Global Security, may make, give or take, by
proxy or proxies, duly appointed in writing, any request, demand,
authorization, direction, notice, consent, waiver or other action provided or
permitted in this Indenture to be made, given or taken by Holders, and a
Depositary that is a Holder of a Global Security may provide its proxy or
proxies to the beneficial owners of interests in any such Global Security.

      The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series, provided that the
Company may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving or making of any notice,





                                     -9-


<PAGE>   18
declaration, request or direction referred to in the next paragraph. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders
remain Holders after such record date; provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
by Holders of the requisite principal amount of Outstanding Securities of such
series on such record date. Nothing in this paragraph shall be construed to
prevent the Company from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be cancelled and of no effect), and nothing in this paragraph shall be
construed to render ineffective any action taken by Holders of the requisite
principal amount of Outstanding Securities of the relevant series on the date
such action is taken. Promptly after any record date is set pursuant to this
paragraph, the Company, at its own expense, shall cause notice of such record
date, the proposed action by Holders and the applicable Expiration Date to be
given to the Trustee in writing and to each Holder of Securities of the
relevant series in the manner set forth in Section 106.

      The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
join in the giving or making of (i) any Notice of Default, (ii) any declaration
of acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred to in
Section 512, in each case with respect to Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date; provided that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and
with no action by any Person be cancelled and of no effect), and nothing in
this paragraph shall be construed to render ineffective any action taken by
Holders of the requisite principal amount of Outstanding Securities of the
relevant series on the date such action is taken. Promptly after any record
date is set pursuant to this paragraph, the Trustee, at the Company's expense,
shall cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Company in writing and to each
Holder of Securities of the relevant series in the manner set forth in Section
106.

      With respect to any record date set pursuant to this Section, the party
hereto which sets such record dates may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day; provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in
Section 106, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this





                                      -10-
<PAGE>   19
Section, the party hereto which set such record date shall be deemed to have
initially designated the 180th day after such record date as the Expiration
Date with respect thereto, subject to its right to change the Expiration Date
as provided in this paragraph.  Notwithstanding the foregoing, no Expiration
Date shall be later than the 180th day after the applicable record date.

      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.


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

      Any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with,

         (1)  the Trustee by any Holder or by the Company shall be sufficient
   for every purpose hereunder if made, given, furnished or filed in writing to
   or with the Trustee at its Corporate Trust Office, Attention: Corporate
   Trust Administration, or

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


SECTION 106.  Notice to Holders; Waiver.

      Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice. In any case where notice to Holders
is given by mail, neither the failure to mail such notice, nor any defect in
any notice so mailed, to any particular Holder shall affect the sufficiency of
such notice with respect to other Holders. Where this Indenture provides for
notice in any manner, such notice may be waived in writing by the Person
entitled to receive such notice, either before or after the event, and such
waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.





                                     -11-
<PAGE>   20
      In case by reason of the suspension of regular mail service or by reason
of any other cause it shall be impracticable to give such notice by mail, then
such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.


SECTION 107.  Conflict with Trust Indenture Act.

      If any provision hereof limits, qualifies or conflicts with a provision
of the Trust Indenture Act which is required under such Act to be a part of and
govern this Indenture, the latter provision shall control. If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
which may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be.


SECTION 108.  Effect of Headings and Table of Contents.

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


SECTION 109.  Successors and Assigns.

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


SECTION 110.  Separability Clause.

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


SECTION 111.  Benefits of Indenture.

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


SECTION 112.  Governing Law.

      This Indenture and the Securities shall be governed by and construed in
accordance with the law of the State of New York.

SECTION 113.  Legal Holidays.

      In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the
Securities (other than a provision of any Security which specifically states
that such provision shall apply in lieu of this Section)) payment of interest
or principal (and premium, if any) need not be made at such Place of Payment on
such date, but may be made on the next succeeding Business Day at such Place of
Payment with the same force and effect as if made on the Interest Payment Date
or Redemption Date, or at the Stated Maturity.

of this Security shall not have the right to institute any proceeding with
respect to the Indenture or for the appointment of a receiver or trustee or for
any other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made
written request to the Trustee to institute proceedings in respect of such
Event of Default as Trustee and offered the Trustee reasonable indemnity, and

amount of Securities of this series at the time Outstanding a direction
inconsistent with such request, and shall have failed to institute any such
proceeding, for 60 days after receipt of such notice, request and offer of
indemnity. The foregoing shall not apply to any suit instituted by the Holder

                                      -23-
<PAGE>   32
      At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series executed by
the Company to the Trustee for authentication, together with a Company Order
for the authentication and delivery of such Securities, and the Trustee in
accordance with the Company Order shall authenticate and deliver such
Securities. If the form or terms of the Securities of the series have been
established by or pursuant to one or more Board Resolutions as permitted by
Sections 201 and 301, in authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such
Securities, the Trustee shall be entitled to receive, and (subject to Section
601) shall be fully protected in relying upon, an Opinion of Counsel stating,

       (1) if the form of such Securities has been established by or pursuant
   to Board Resolution as permitted by Section 201, that such form has been
   established in conformity with the provisions of this Indenture;

       (2) if the terms of such Securities have been established by or pursuant
   to Board Resolution as permitted by Section 301, that such terms have been
   established in conformity with the provisions of this Indenture; and

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

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

      Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
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.

      Each Security shall be dated the date of its authentication.

      No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder. Notwithstanding
the foregoing, if any Security shall have been authenticated





                                      -24-
<PAGE>   33
and delivered hereunder but never issued and sold by the Company, and
the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 309, for all purposes of this Indenture such Security shall
be deemed never to have been authenticated and delivered hereunder and shall
never be entitled to the benefits of this Indenture.


SECTION 304.  Temporary Securities.

      Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

      If temporary Securities of any series are issued, the Company will cause
definitive Securities of that series to be prepared without unreasonable delay.
After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for definitive Securities of
such series upon surrender of the temporary Securities of such series at the
office or agency of the Company in a Place of Payment for that series, without
charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities of any series, the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor one or more definitive
Securities of the same series, of any authorized denominations and of like
tenor and aggregate principal amount. 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 and tenor.


SECTION 305.  Registration; Registration of Transfer and Exchange.

      The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register  maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is
hereby appointed "Security Registrar" for the purpose of registering Securities
and transfers of Securities as herein provided.

      Upon surrender for registration of transfer of any Security of a series
at the office or agency of the Company in a Place of Payment for that series,
the Company shall execute, and the Trustee shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new
Securities of the same series, of any authorized denominations and of like
tenor and aggregate principal amount.





                                      -25-
<PAGE>   34
      At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series, of any authorized denominations and of
like tenor and aggregate principal amount, upon surrender of the Securities to
be exchanged at such office or agency. Whenever any Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange
is entitled to receive.

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

      Every Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Company or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

      No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

      If the Securities of any series (or of any series and specified tenor)
are to be redeemed in part, the Company shall not be required (A) to issue,
register the transfer of or exchange any Securities of that series (or of that
series and specified tenor, as the case may be) during a period beginning at
the opening of business 15 days before the day of the mailing of a notice of
redemption of any such Securities selected for redemption under Section 1103
and ending at the close of business on the day of such mailing, or (B) to
register the transfer of or exchange any Security so selected for redemption in
whole or in part, except the unredeemed portion of any Security being redeemed
in part.

      The provisions of Clauses (1), (2), (3) and (4) below shall apply only to
Global Securities:

       (1) Each Global Security authenticated under this Indenture shall be
      registered in the name of the Depositary designated for such Global
      Security or a nominee thereof and delivered to such Depositary or a
      nominee thereof or custodian therefor, and each such Global Security
      shall constitute a single Security for all purposes of this Indenture.

       (2) Notwithstanding any other provision in this Indenture, no Global
      Security may be exchanged in whole or in part for Securities registered,
      and no transfer of a Global Security in whole or in part may be
      registered, in the name of any Person other than the Depositary for such
      Global Security or a nominee thereof unless (A) such Depositary (i) has
      notified the Company that it is unwilling or unable to continue as





                                     -26-
<PAGE>   35
   Depositary for such Global Security and no successor Depositary has been
   appointed within 90 days or (ii) has ceased to be a clearing agency
   registered under the Exchange Act, (B) there shall have occurred and be
   continuing an Event of Default with respect to such Global Security, (C) the
   Company, in its sole discretion, has determined that securities of any
   series issued in the form of one or more Global Securities shall no longer
   be represented by such Global Security or Global Securities or (D) there
   shall exist such circumstances, if any, in addition to or in lieu of the
   foregoing as have been specified for this purpose as contemplated by Section
   301.

       (3) Subject to Clause (2) above, any exchange of a Global Security for
   other Securities may be made in whole or in part, and all Securities issued
   in exchange for a Global Security or any portion thereof shall be registered
   in such names as the Depositary for such Global Security shall direct.

       (4) Every Security authenticated and delivered upon registration of
   transfer of, or in exchange for or in lieu of, a Global Security or any
   portion thereof, whether pursuant to this Section, Section 304, 306, 906 or
   1107 or otherwise, shall be authenticated and delivered in the form of, and
   shall be, a Global Security, unless such Security is registered in the name
   of a Person other than the Depositary for such Global Security or a nominee
   thereof.


SECTION 306.  Mutilated, Destroyed, Lost and Stolen Securities.

      If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

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

      In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

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





                                      -27-
<PAGE>   36
      Every new Security of any series issued pursuant to this Section in lieu
of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall
be entitled to all the benefits of this Indenture equally and proportionately
with any and all other Securities of that series duly issued hereunder.

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


SECTION 307.  Payment of Interest; Interest Rights Preserved.

      Except as otherwise provided as contemplated by Section 301 with respect
to any series of Securities, interest on any Security which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date shall be
paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

      Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:

         (1)     The Company may elect to make payment of any Defaulted
      Interest to the Persons in whose names the Securities of such series (or
      their respective Predecessor Securities) are registered at the close of
      business on a Special Record Date for the payment of such Defaulted
      Interest, which shall be fixed in the following manner. The Company shall
      notify the Trustee in writing of the amount of Defaulted Interest
      proposed to be paid on each Security of such series and the date of the
      proposed payment, and at the same time the Company shall deposit with the
      Trustee an amount of money equal to the aggregate amount proposed to be
      paid in respect of such Defaulted Interest or shall make arrangements
      satisfactory to the Trustee for such deposit prior to the date of the
      proposed payment, such money when deposited to be held in trust for the
      benefit of the Persons entitled to such Defaulted Interest as in this
      Clause provided. Thereupon the Trustee shall fix a Special Record Date
      for the payment of such Defaulted Interest which shall be not more than
      15 days and not less than 10 days 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 given to
      each Holder of Securities of such series in the manner set forth in
      Section 106, not less than 10 days prior to such Special Record Date.
      Notice of the proposed payment of such Defaulted Interest and the Special





                                     -28-
<PAGE>   37
      Record Date therefor having been so mailed, such Defaulted Interest shall
      be paid to the Persons in whose names the Securities of such series (or
      their respective Predecessor Securities) are registered at the close of
      business on such Special Record Date and shall no longer be payable
      pursuant to the following Clause (2).

         (2)  The Company may make payment of any Defaulted Interest on the
      Securities of any series in any other lawful manner not inconsistent
      with the  requirements of any securities exchange on which such
      Securities may be listed, and upon such notice as may be required by such
      exchange, if, after notice given by the Company to the Trustee of the
      proposed payment pursuant to this Clause, such manner of payment shall be
      deemed practicable by the Trustee.

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


SECTION 308.  Persons Deemed Owners.

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


SECTION 309.  Cancellation.

      All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly cancelled by it. The Company may at any time deliver to
the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and may deliver to the Trustee (or to any other Person for delivery
to the Trustee) for cancellation any Securities previously authenticated
hereunder which the Company has not issued and sold, and all Securities so
delivered shall be promptly cancelled by the Trustee. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as
provided in this Section, except as expressly permitted by this Indenture. All
cancelled Securities held by the Trustee shall be disposed of as directed by a
Company Order.

SECTION 310.  Computation of Interest.

      Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.


                                  ARTICLE FOUR

                           SATISFACTION AND DISCHARGE


SECTION 401.  Satisfaction and Discharge of Indenture.

      This Indenture shall upon Company Request cease to be of further effect
(except as to any surviving rights of registration of transfer or exchange of
Securities herein expressly provided for), and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

      (1)  either

         (A)  all Securities theretofore authenticated and delivered (other
      than (i) Securities which have been destroyed, lost or stolen and which
      have been replaced or paid as provided in Section 306 and (ii) Securities
      for whose payment money has theretofore been deposited in trust or
      segregated and held in trust by the Company and thereafter repaid to the
      Company or discharged from such trust, as provided in Section 1003) have
      been delivered to the Trustee for cancellation; or

         (B)  all such Securities not theretofore delivered to the Trustee for
      cancellation

           (i)   have become due and payable, or

           (ii)  will become due and payable at their Stated Maturity within
         one year, or

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

      and the Company, in the case of (i), (ii) or (iii) above, has deposited
      or caused to be deposited with the Trustee as trust funds in trust for
      the purpose money in an amount sufficient to pay and discharge the entire
      indebtedness on such Securities not theretofore delivered to the Trustee
      for cancellation, for principal and any premium and interest to the date
      of such deposit (in the case of Securities which have become due and
      payable) or to the Stated Maturity or Redemption Date, as the case may
      be;

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


                                     -30-
<PAGE>   39

      (3)  the Company has delivered to the Trustee an Officers' Certificate
   and an Opinion of Counsel, each stating that all conditions precedent herein
   provided for relating to the satisfaction and discharge of this Indenture
   have been complied with.

      Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of
this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.


SECTION 402.  Application of Trust Money.

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

                                    REMEDIES


SECTION 501.  Events of Default.

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

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

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

      (3)  default in the deposit of any sinking fund payment, when and as due
   by the terms of a Security of that series; or

      (4)  default in the performance, or breach, of any covenant or warranty
   of the Company in this Indenture (other than a covenant or warranty a
   default in whose performance or whose breach is elsewhere in this Section
   specifically dealt with or





                                     -31-
<PAGE>   40
   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 30 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 not less than 25% in principal
   amount of the Outstanding Securities of that series a written notice
   specifying such default or breach and requiring it to be remedied and
   stating that such notice is a "Notice of Default" hereunder; or

        (5) a default under any bond, debenture, note or other evidence of
   indebtedness for money borrowed by the Company or any Principal Subsidiary
   Bank (including a default with respect to Securities of any series other
   than that series) having an aggregate  principal amount outstanding of in
   excess of $5,000,000, or under any mortgage, indenture or instrument
   (including this Indenture) under which there may be issued or by which there
   may be secured or evidenced any indebtedness for money borrowed by the
   Company or any Principal Subsidiary Bank having an aggregate principal
   amount outstanding of in excess of $5,000,000, whether such indebtedness now
   exists or shall hereafter be created, which default (A) shall constitute a
   failure to pay any portion of the principal of such indebtedness when due
   and payable after the expiration of any applicable grace period with respect
   thereto or (B) shall have resulted in such indebtedness becoming or being
   declared due and payable prior to the date on which it would otherwise have
   become due and payable, without, in the case of Clause (A), such
   indebtedness having been discharged or without, in the case of Clause (B),
   such indebtedness having been discharged or such acceleration having been
   rescinded or annulled, in each such case within a period of 30 days after
   there shall have been given, by registered or certified mail, to the Company
   by the Trustee or to the Company and the Trustee by the Holders of at least
   10% in principal amount of the Outstanding Securities of that series a
   written notice specifying such default and requiring the Company to cause
   such indebtedness to be discharged or cause such acceleration to be
   rescinded or annulled, as the case may be, and stating that such notice is a
   "Notice of Default" hereunder; provided, however, that, subject to the
   provisions of Sections 601 and 602, the Trustee shall not be deemed to have
   knowledge of such default unless either (A) a Responsible Officer of the
   Trustee shall have actual knowledge of such default or (B) the Trustee shall
   have received written notice thereof from the Company, from any Holder, from
   the holder of any such indebtedness or from the trustee under any such
   mortgage, indenture or other instrument; or

      (6)  the entry by a court or governmental authority having jurisdiction
   in the premises of (A) a decree or order for relief in respect of the
   Company or any Principal Subsidiary Bank in an involuntary case or
   proceeding under any applicable Federal or State bankruptcy, insolvency,
   reorganization or other similar law or (B) a decree or order adjudging the
   Company or any Principal Subsidiary 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 any Principal
   Subsidiary Bank under any applicable Federal or State law, or appointing a
   custodian, receiver, liquidator, assignee, trustee, sequestrator or other
   similar official





                                     -32-
<PAGE>   41
   of the Company or any Principal Subsidiary Bank or of any substantial part
   of its property, or ordering the winding up or liquidation of its affairs,
   and the continuance of any such decree or order for relief or any such other
   decree or order unstayed and in effect for a period of 60 consecutive days;
   or

      (7)  the commencement by the Company or any Principal Subsidiary Bank of
   a voluntary case or proceeding under any applicable Federal or State
   bankruptcy, insolvency, reorganization or other similar law or of any other
   case or proceeding to be adjudicated a bankrupt or insolvent, or the consent
   by it to the entry of a decree or order for relief in respect of the Company
   or any Principal Subsidiary Bank in an involuntary case or proceeding under
   any applicable Federal or State bankruptcy, insolvency, reorganization or
   other similar law or to the commencement of any bankruptcy or insolvency
   case or proceeding against it, or the filing by it of a petition or answer
   or consent seeking reorganization or relief under any applicable Federal or
   State law, or the consent by it to the filing of such petition or to the
   appointment of or taking possession by a custodian, receiver, liquidator,
   assignee, trustee, sequestrator or other similar official of the Company or
   any Principal Subsidiary Bank or of any substantial part of its property, or
   the making by it of an assignment for the benefit of creditors, or the
   admission by it in writing of its inability to pay its debts generally as
   they become due, or the taking of corporate action by the Company or any
   Principal Subsidiary Bank in furtherance of any such action; or

      (8)  any other Event of Default provided with respect to Securities of
   that series.


SECTION 502.  Acceleration of Maturity; Rescission and Annulment.

      If an Event of Default (other than an Event of Default specified in
Section 501(6) or 501(7)) with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or
the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series may declare the principal amount of all the
Securities of that series (or, if any Securities of that series are Original
Issue Discount Securities, such portion of the principal amount of such
Securities as may be specified by the terms thereof) to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal amount (or specified
amount) shall become immediately due and payable.  If an Event of Default
specified in Section 501(6) or 501 (7) with respect to Securities of any series
at the time Outstanding occurs, the principal amount of all the Securities of
that series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be
specified by the terms thereof) shall automatically, and without any
declaration or other action on the part of the Trustee or any Holder, 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





                                     -33-
<PAGE>   42
majority in principal amount of the Outstanding Securities of that series, by
written notice to the Company and the Trustee, may rescind and annul such
declaration and its consequences if

 (1)  the Company has paid or deposited with the Trustee a sum sufficient to pay

         (A)  all overdue interest on all Securities of that series,

         (B)  the principal of (and premium, if any, on) any Securities of that
      series which have become due otherwise than by such declaration of
      acceleration and any interest thereon at the rate or rates prescribed
      therefor in such Securities,

         (C)  to the extent that payment of such interest is lawful, interest
      upon overdue interest at the rate or rates prescribed therefor in such
      Securities, and

         (D)  all sums paid or advanced by the Trustee hereunder and the
      reasonable compensation, expenses, disbursements and advances of the
      Trustee, its agents and counsel;

   and

      (2)  all 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 513.

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


SECTION 503.  Collection of Indebtedness and Suits for Enforcement by Trustee.

      The Company covenants that if

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

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

      (3)  default is made in the making or satisfaction of any sinking fund
   payment or analogous obligation when the same becomes due pursuant to the
   terms of such Security,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal and any premium interest and sinking fund obligation
and, to the extent that payment





                                     -34-
<PAGE>   43
of such interest shall be legally enforceable, interest on any overdue
principal, premium or sinking fund obligation and on any overdue interest, at
the rate or rates prescribed therefor in such Securities, and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

      If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series
by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.


SECTION 504.  Trustee May File Proofs of Claim.

      In case of any judicial proceeding relative to the Company (or any other
obligor upon the Securities), its property or its creditors, the Trustee shall
be entitled and empowered, by intervention in such proceeding or otherwise, to
take any and all actions authorized under the Trust Indenture Act in order to
have claims of the Holders and the Trustee allowed in any such proceeding. In
particular, the Trustee shall be authorized to collect and receive any moneys
or other property payable or deliverable on any such claims and to distribute
the same; and any custodian, receiver, assignee, trustee, liquidator,
sequestrator or other similar official in any such judicial proceeding is
hereby authorized by each Holder to make such payments to the Trustee and, in
the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, and any other amounts due the Trustee under Section
607.

      No provision of this Indenture shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding; provided,
however, that the Trustee may, on behalf of the Holders, vote for the election
of a trustee in bankruptcy or similar official and be a member of a creditors'
or other similar committee.

SECTION 505.  Trustee May Enforce Claims Without Possession of Securities.

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





                                     -35-
<PAGE>   44
and any recovery of judgment shall, after provision for the payment of the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, be for the ratable benefit of the Holders of the
Securities in respect of which such judgment has been recovered.

      (2)  the Holders of not less than 25% in principal amount of the
   Outstanding Securities of that series shall have made written request to the
   Trustee to institute proceedings in respect of such Event of Default in its
   own name as Trustee hereunder;

of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all of such
Holders.

not be impaired without the consent of such Holder.

cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent
the concurrent assertion or employment of any other appropriate right or
remedy.


SECTION 511.  Delay or Omission Not Waiver.

      No delay or omission of the Trustee or of any Holder of any Securities to
exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or

<PAGE>   46

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

      (1)  such direction shall not be in conflict with any rule of law or
    with this Indenture, and                                       
                                    
      (2)  the Trustee may take any other action deemed proper by the Trustee
    which is not inconsistent with such direction.

      The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any past default hereunder with respect to such

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

      (2)  in respect of a covenant or provision hereof which under Article
    Nine cannot be modified or amended without the consent of the Holder of each
    Outstanding Security of such series affected.

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


SECTION 514.  Undertaking for Costs.

Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit
to file an undertaking to pay the costs of such suit, and may assess costs
against any such party litigant, in the manner and to the extent provided in
the Trust Indenture Act; provided that neither this Section nor the Trust
Indenture Act shall be deemed to authorize any court to require such an





                                     -38-
<PAGE>   47
undertaking or to make such an assessment in any suit instituted by the
Company, by such Trustee or by a Holder or group of Holders holding in the
aggregate more than 10% in principal amount of the Outstanding Securities of
any series, or to any suit instituted by any Holder for the enforcement of the
payment of the principal of (or premium, if any) or interest on any Securities

in the case of redemption, on or after the Redemption Date).


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

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


                                  ARTICLE SIX

SECTION 601.  Certain Duties and Responsibilities.

      The duties and responsibilities of the Trustee shall be as provided by
the Trust Indenture Act. Notwithstanding the foregoing, 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.
Whether or not therein expressly so provided, every provision of this Indenture
relating to the conduct or affecting the liability of or affording protection
to the Trustee shall be subject to the provisions of this Section.


SECTION 602.  Notice of Defaults.

      If a default occurs hereunder with respect to Securities of any series,
the Trustee shall give the Holders of Securities of such series notice of such
default as and to the extent provided by the Trust Indenture Act; provided,
however, that in the case of any default of the character specified in Section
501(4) with respect to Securities of such series, no such notice to Holders
shall be given until at least 30 days after the occurrence thereof. For the
purpose of this Section, the term "default" means any event which is,





                                     -39-

      (1)  the Trustee may rely and shall be protected in acting or refraining
   from acting upon any resolution, certificate, statement, instrument,

   sufficiently evidenced by a Company Request or Company Order, and any
   resolution of the Board of Directors shall be sufficiently evidenced by a

   deem it desirable that a matter be proved or established prior to taking,

   on its part, rely upon an Officers' Certificate;

      (4)  the Trustee may consult with counsel and the written advice of such
   counsel or any Opinion of Counsel shall be full and complete authorization
   and protection in respect of any action taken, suffered or omitted by it
   hereunder in good faith and in reliance thereon;

      (5)  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;

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

      (7)  the Trustee may execute any of the trusts or powers hereunder or
   perform any duties hereunder either directly or by or through agents or

SECTION 604.  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 any
responsibility for their correctness. The Trustee makes no representations as
to the validity or sufficiency of this Indenture or of the Securities. Neither
the Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Company of Securities or the proceeds thereof.


SECTION 605.  May Hold Securities.

      The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to
Sections 608 and 613, may otherwise deal with the Company with the same rights
it would have if it were not Trustee, Authenticating Agent, Paying Agent,
Security Registrar or such other agent.


SECTION 606.  Money Held in Trust.

      Money held by the Trustee in trust hereunder need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no

otherwise agreed with the Company.


SECTION 607.  Compensation and Reimbursement.

      The Company agrees

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

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

      (3)  to indemnify the Trustee for, and to hold it harmless against, any
   loss, liability or expense incurred without negligence or bad faith on its
   part, arising out of or in connection with the acceptance or administration
   of the trust or trusts hereunder,





                                     -41-
<PAGE>   50
   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.

SECTION 608.  Conflicting Interests.

      If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
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 such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series.


SECTION 609.  Corporate Trustee Required; Eligibility.

      There shall at all times be one (and only one) Trustee hereunder with
respect to the Securities of each series, which may be Trustee hereunder for
Securities of one or more other series.  Each Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such, and has a combined
capital and surplus of at least $50,000,000 and has its Corporate Trust Office
or agency in the Borough of Manhattan, The City of New York.  If any such
Person publishes reports of condition at least annually, pursuant to law or to
the requirements of its supervising or examining authority, then for the
purposes of this Section and to the extent permitted by the Trust Indenture
Act, the combined capital and surplus of such Person shall be deemed to be its
combined capital and surplus as set forth in its most recent report of
condition so published. If at any time the Trustee with respect to the
Securities of any series shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.


SECTION 610.  Resignation and Removal; Appointment of Successor.

      No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.

      The Trustee may resign at any time with respect to the Securities of one
or more series by giving written notice thereof to the Company.

      The Trustee may be removed at any time with respect to the Securities of
any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Company.

      If the instrument of acceptance by a successor Trustee required by
Section 611 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of





                                     -42-
<PAGE>   51
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

      If at any time:

      (1)  the Trustee shall fail to comply with Section 608 after written
   request therefor by the Company or by any Holder who has been a bona fide
   Holder of a Security for at least six months, or

      (2)  the Trustee shall cease to be eligible under Section 609 and shall
   fail to resign after written request therefor by the Company or by any such
   Holder, or

      (3)  the Trustee shall become incapable of acting or shall be adjudged a
   bankrupt or insolvent or a receiver of the Trustee or of its property shall
   be appointed or any public officer shall take charge or control of the
   Trustee or of its property or affairs for the purpose of rehabilitation,
   conservation or liquidation,

then, in any such case, (A) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (B) subject to Section 514, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

      If the Trustee shall resign, be removed or become incapable of acting, or
if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Company, by a Board Resolution,
shall promptly appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all
of such series and that at any time there shall be only one Trustee with
respect to the Securities of any particular series) and shall comply with the
applicable requirements of Section 611. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its
acceptance of such appointment in accordance with the applicable requirements
of Section 611, become the successor Trustee with respect to the Securities of
such series and to that extent supersede the successor Trustee appointed by the
Company. If no successor Trustee with respect to the Securities of any series
shall have been so appointed by the Company or the Holders and accepted
appointment in the manner required by Section 611, any Holder who has been a
bona fide Holder of a Security of such series for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.





                                     -43-
<PAGE>   52
      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 to all Holders
of Securities of such series in the manner provided in Section 106. Each notice
shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.


SECTION 611.  Acceptance of Appointment by Successor.

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

      In case of the appointment hereunder of a successor Trustee with respect
to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1)
shall contain such provisions as shall be necessary or desirable to transfer
and confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of
that or those series to which the appointment of such successor Trustee
relates, (2) if the retiring Trustee is not retiring with respect to all
Securities, shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series as to
which the retiring Trustee is not retiring shall continue to be vested in the
retiring Trustee, and (3) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental indenture shall constitute such Trustees
co-trustees of the same trust and that each such Trustee shall be trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee; and upon the execution and delivery of
such supplemental indenture the resignation or removal of the retiring Trustee
shall become effective to the extent provided therein and each such successor
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Trustee with respect
to the Securities of that or those series to which the appointment of such
successor Trustee relates; but, on request of the Company or any successor
Trustee, such retiring Trustee shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee
hereunder





                                     -44-
<PAGE>   53
with respect to the Securities of that or those series to which the appointment
of such successor Trustee relates.

      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 the
first or second preceding paragraph, as the case may be.

      No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified and eligible under
this Article.


SECTION 612.  Merger, Conversion, Consolidation or Succession to Business.

      Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.


SECTION 613.  Preferential Collection of Claims Against Company.

      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 the Trust Indenture Act regarding the collection of claims
against the Company (or any such other obligor).


SECTION 614.  Appointment of Authenticating Agent.

      The Trustee may appoint an Authenticating Agent or Agents with respect to
one or more series of Securities which shall be authorized to act on behalf of
the Trustee to authenticate Securities of such series issued upon original
issue and upon exchange, registration of transfer or partial redemption thereof
or pursuant to Section 306, and Securities so authenticated shall be entitled
to the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder.  Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee





                                     -45-
<PAGE>   54
by an Authenticating Agent. Each Authenticating Agent shall be acceptable to
the Company and shall at all times be a corporation organized and doing
business under the laws of the United States of America, any State thereof or
the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000
(except that such combined capital and surplus amount shall not apply to First
Chicago Trust Company of New York) and subject to supervision or examination by
Federal or State authority. If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Authenticating Agent shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time an Authenticating Agent shall cease to
be eligible in accordance with the provisions of this Section, such
Authenticating Agent shall resign immediately in the manner and with the effect
specified in this Section.

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

      An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and to the Company. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 106 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

      The Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payments, subject to the provisions
of Section 607.

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





                                     -46-

      This is one of the Securities of the series designated therein referred

      (1)  change the Stated Maturity of the principal of, or any instalment of
   principal of or interest on, any Security, or reduce the principal amount

                                  ARTICLE TEN

                                   COVENANTS


SECTION 1001.  Payment of Principal, Premium and Interest.

      The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any
premium and interest on the Securities of that series in accordance with the
terms of the Securities and this Indenture.


SECTION 1002.  Maintenance of Office or Agency.

      The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Company in respect of the Securities of that series and this Indenture
may be served. The Company will give prompt written notice to the Trustee of
the location, and any change in the location, of such office or agency. If at
any time the Company shall fail to maintain any such required office or agency
or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, and the Company hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

      The Company may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company





                                     -53-
<PAGE>   62
of its obligation to maintain an office or agency in each Place of Payment for
Securities of any series for such purposes. The Company will give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency.


SECTION 1003.  Money for Securities Payments to Be Held in Trust.

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

      Whenever the Company shall have one or more Paying Agents for any series
of Securities, it will, prior to each due date of the principal of or any
premium or interest on any Securities of that series, deposit with a Paying
Agent a sum sufficient to pay such amount, such sum to be held as provided by
the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its action or failure so to act.

      The Company will cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will (1) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the
Securities of that series, upon the written request of the Trustee, forthwith
pay to the Trustee all sums held in trust by such Paying Agent for payment in
respect of the Securities of that series.

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

      Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of or any premium or
interest on any Security of any series 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 shall
thereafter, as an unsecured general creditor, look





                                     -54-
<PAGE>   63
only to the Company for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in a newspaper
published in the English language, customarily published on each Business Day
and of general circulation in the Borough of Manhattan, The City of New York,
notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.


SECTION 1004.  Statement by Officers as to Default.

      The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year of the Company ending after the date hereof, an Officers'
Certificate, stating whether or not to the best knowledge of the signers
thereof the Company is in default in the performance and observance of any of
the terms, provisions and conditions of this Indenture (without regard to any
period of grace or requirement of notice provided hereunder) and, if the
Company shall be in default, specifying all such defaults and the nature and
status thereof of which they may have knowledge. The Company shall deliver to
the Trustee written notice of the occurrence of any Default within ten Business
Days of the Company becoming aware thereof.


SECTION 1005.  Existence.

      Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence and that of each Principal Subsidiary and the rights (charter and
statutory) and franchises of the Company and each Principal Subsidiary Bank;
provided, however, that the Company shall not be required to preserve any such
right or franchise if the Board of Directors shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company and its Principal Subsidiary Banks and that the loss thereof is not
disadvantageous in any material respect to the Holders.


SECTION 1006.  Maintenance of Properties.

      The Company will cause all properties used or useful in the conduct of
its business or the business of any Subsidiary to be maintained and kept in
good condition, repair and working order and supplied with all necessary
equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided,
however, that nothing in this Section shall prevent the Company from
discontinuing the operation or maintenance of any of such properties if such





                                     -55-
<PAGE>   64
discontinuance is, in the judgment of the Company, desirable in the conduct of
its business or the business of any Subsidiary and not disadvantageous in any
material respect to the Holders.


SECTION 1007.  Payment of Taxes and Other Claims.

      The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income, profits or property of the Company or any Subsidiary, and (2)
all lawful claims for labor, materials and supplies which, if unpaid, might by
law become a lien upon the property of the Company or any Subsidiary; provided,
however, that the Company shall not be required to pay or discharge or cause to
be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings and for which adequate provision is made.


SECTION 1008.  Limitation Upon Disposition of Stock or Assets of the Bank.

      So long as any of the Securities shall be outstanding, but subject to the
provisions of Article Eight, the Company will not and will not permit any
Subsidiary to, sell, assign, transfer, grant a security interest in or
otherwise dispose of any shares of, securities convertible into or options,
warrants or rights to subscribe for or purchase shares of, Voting Stock (other
than directors' qualifying shares) of any Principal Subsidiary Bank, nor will
it permit any Principal Subsidiary Bank or any Subsidiary owning, directly or
indirectly, any shares of Voting Stock of a Principal Subsidiary Bank to issue
(except to the Company) any shares of, or securities convertible into, or
options, warrants or rights to subscribe for or purchase, shares of, Voting
Stock of any Principal Subsidiary Bank except for sales, assignments,
transfers, grants of security interest or other dispositions which: (i) are for
fair market value on the date thereof, as determined by the Board of Directors
of the Company (which determination shall be conclusive) and evidenced by a
duly adopted resolution thereof (provided, that if such consideration includes
securities of any Person, such Person would not be an Affiliate of the Company
immediately after the consummation of such transaction), and after giving
effect to such disposition and to any possible dilution (and assuming, for
purposes of this clause (i), that all such convertible securities have been
fully converted and all such options, warrants or rights have been fully
exercised), the Company will own at least 80% of the Voting Stock of such
Principal Subsidiary Bank then issued and outstanding free and clear of any
security interest; (ii) are made in compliance with an order of a court or
regulatory authority of competent jurisdiction, a condition imposed by any such
court or authority permitting the acquisition by the Company, directly or
indirectly, of any other bank or entity the activities of which are legally
permissible for a bank holding company or a subsidiary thereof to engage in, or
an undertaking made to such authority in connection with such an acquisition
provided that the assets of the bank or entity to be acquired and its
consolidated subsidiaries are equal to at least 75% of the assets of such
Principal Subsidiary Bank or such Subsidiary owning, directly or indirectly,
any shares of voting





                                      -56-
<PAGE>   65
stock of such Principal Subsidiary Bank and its consolidated subsidiaries on
the date of acquisition, calculated in accordance with generally accepted
accounting principles;  or (iii) are made to the Company or any Wholly-Owned 
Subsidiary if such Wholly-Owned Subsidiary by supplemental indenture agrees to 
be bound by this covenant as if it were the Company and the Company by 
supplemental indenture agrees to maintain such Wholly-Owned Subsidiary as a 
Wholly-Owned Subsidiary. Notwithstanding the foregoing, any Principal 
Subsidiary Bank may be merged into or consolidated with another banking 
institution organized under the laws of the United States, any State thereof 
or the District of Columbia, if after giving effect to such merger or 
consolidation the Company or any Wholly-Owned Subsidiary owns at least 80% of 
the Voting Stock of such other banking institution then issued and outstanding 
free and clear of any security interest and if, immediately after giving 
effect thereto and treating any such resulting banking institution thereafter 
as such Principal Subsidiary Bank and as a Subsidiary for purposes of this 
Indenture, no Event of Default, and no event which, after notice or lapse of 
time or both, would become an Event of Default, shall have happened and be 
continuing.


SECTION 1009.  Waiver of Certain Covenants.

      Except as otherwise specified as contemplated by Section 301 for
Securities of such series, the Company may, with respect to the Securities of
any series, omit in any particular instance to comply with any term, provision
or condition set forth in any covenant provided pursuant to Section 301(18),
901(2) or 901(7) for the benefit of the Holders of such series or in Section
1008 if before the time for such compliance the Holders of not less than a
majority in principal amount of the Outstanding Securities of such series
shall, by Act of such Holders, either waive such compliance in such instance or
generally waive compliance with such term, provision or condition, but no such
waiver shall extend to or affect such term, provision or condition except to
the extent so expressly waived, and, until such waiver shall become effective,
the obligations of the Company and the duties of the Trustee in respect of any
such term, provision or condition shall remain in full force and effect.

                            REDEMPTION OF SECURITIES


SECTION 1101.  Applicability of Article.

      Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for such Securities) in
accordance with this Article.

SECTION 1102.  Election to Redeem; Notice to Trustee.

      The election of the Company to redeem any Securities shall be evidenced
by a Board Resolution or in another manner specified as contemplated by Section
301 for such Securities. In case of any redemption at the election of the
Company of less than all the Securities of any series (including any such
redemption affecting only a single Security), the Company shall, at least 60
days prior to the Redemption Date fixed by the Company (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such Redemption
Date, of the principal amount of Securities of such series to be redeemed and,
if applicable, of the tenor of the Securities to be redeemed. In the case of
any redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction.


SECTION 1103.  Selection by Trustee of Securities to Be Redeemed.

      If less than all the Securities of any series are to be redeemed (unless
all the Securities of such series and of a specified tenor are to be redeemed
or unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of
a portion of the principal amount of any Security of such series, provided that
the unredeemed portion of the principal amount of any Security shall be in an
authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security. If less than all the Securities of such series
and of a specified tenor are to be redeemed (unless such redemption affects
only a single Security), the particular Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by the Trustee,
from the Outstanding Securities of such series and specified tenor not
previously called for redemption in accordance with the preceding sentence.

      The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption as aforesaid and, in case of any Securities
selected for partial redemption as aforesaid, the principal amount thereof to
be redeemed.

      The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting a series of Securities comprised of only a
single Security, whether such Security is to be redeemed in whole or in part.
In the case of any such redemption in part, the unredeemed portion of the
principal amount of the Security shall be in an authorized denomination (which
shall not be less than the minimum authorized denomination) for such Security.

      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





                                     -58-
<PAGE>   67
Securities redeemed or to be redeemed only in part, to the portion of the
principal amount of such Securities which has been or is to be redeemed.


SECTION 1104.  Notice of Redemption.

      Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at his address appearing in the
Security Register.

      All notices of redemption shall state:

      (1)  the Redemption Date,

      (2)  the Redemption Price,

      (3)  if less than all the Outstanding Securities of any series consisting
   of more than a single Security are to be redeemed, the identification (and,
   in the case of partial redemption of any such Securities, the principal
   amounts) of the particular Securities to be redeemed and, if less than all
   the entire principal amount of any series consisting of a single Security
   are to be redeemed, the principal portion of the amount of the particular
   Security to be redeemed,

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

      (5)  the CUSIP numbers, if any, of the Securities to be redeemed,

      (6)  the place or places where each such Security is to be surrendered
   for payment of the Redemption Price, and

      (7)  that the redemption is for a sinking fund, if such is the case.

      Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company and shall be irrevocable.


SECTION 1105.  Deposit of Redemption Price.

      Prior to any Redemption Date, the Company shall deposit with the Trustee
or with a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 1003) an amount of money
sufficient to pay the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date.





                                     -59-
<PAGE>   68
SECTION 1106.  Securities Payable on Redemption Date.

      Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security
shall be paid by the Company at the Redemption Price, together with accrued
interest to the Redemption Date; provided, however, that, unless otherwise
specified as contemplated by Section 301, installments of interest whose Stated
Maturity is on or prior to the Redemption Date will be payable to the Holders
of such Securities, or one or more Predecessor Securities, registered as such
at the close of business on the relevant Record Dates according to their terms
and the provisions of Section 307.

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


SECTION 1107.  Securities Redeemed in Part.

      Any Security which is to be redeemed only in part shall be surrendered at
a Place of Payment therefor (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Company and the Trustee duly executed by, the Holder thereof or his
attorney duly authorized in writing), and the Company shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Security without
service charge, a new Security or Securities of the same series and of like
tenor, of any authorized denomination as requested by such Holder, in aggregate
principal amount equal to and in exchange for the unredeemed portion of the
principal of the Security so surrendered.


                                 ARTICLE TWELVE

                                 SINKING FUNDS


SECTION 1201.  Applicability of Article.

      The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of any series except as otherwise specified as
contemplated by Section 301 for such Securities.

      The minimum amount of any sinking fund payment provided for by the terms
of any Securities 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
such Securities is herein





                                     -60-
<PAGE>   69
referred to as an "optional sinking fund payment". If provided for by the terms
of any Securities, the cash amount of any sinking fund payment may be subject
to reduction as provided in Section 1202. Each sinking fund payment shall be
applied to the redemption of Securities as provided for by the terms of such
Securities.


SECTION 1202.  Satisfaction of Sinking Fund Payments with Securities.

      The Company (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been redeemed either at the election of the
Company pursuant to the terms of such Securities or which have otherwise been
acquired by the Company or through the application of permitted optional
sinking fund payments pursuant to the terms of such Securities, in each case in
satisfaction of all or any part of any sinking fund payment with respect to any
Securities of such series required to be made pursuant to the terms of such
Securities as and to the extent provided for by the terms of such Securities;
provided that the Securities to be so credited have not been previously so
credited. The Securities to be so credited shall be received and credited for
such purpose by the Trustee at the Redemption Price, as specified in the
Securities so to be redeemed, for redemption through operation of the sinking
fund and the amount of such sinking fund payment shall be reduced accordingly.


SECTION 1203.  Redemption of Securities for Sinking Fund.

      Not less than 60 days prior to each sinking fund payment date for any
Securities, the Company  will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, 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 pursuant
to Section 1202 and will also deliver to the Trustee any Securities to be so
delivered. Not less than 30 days prior to each such sinking fund payment date,
the Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 1104. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1106 and 1107.

                       DEFEASANCE AND COVENANT DEFEASANCE


SECTION 1301.  Company's Option to Effect Defeasance or Covenant Defeasance.

      The Company may elect, at its option at any time, to have Section 1302 or
Section 1303 applied to any Securities or any series of Securities, as the case
may be, designated pursuant to Section 301 as being defeasible pursuant to such
Section 1302 or 1303, in accordance with any applicable requirements provided
pursuant to Section 301 and upon compliance with the conditions set forth below
in this Article. Any such election shall be evidenced by a Board Resolution or
in another manner specified as contemplated by Section 301 for such Securities.


SECTION 1302.  Defeasance and Discharge.

      Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, the
Company shall be deemed to have been discharged from its obligations with
respect to such Securities as provided in this Section on and after the date
the conditions set forth in Section 1304 are satisfied (hereinafter called
"Defeasance"). For this purpose, such Defeasance means that the Company shall
be deemed to have paid and discharged the entire indebtedness represented by
such Securities and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), subject to the following which shall survive until
otherwise terminated or discharged hereunder: (1) the rights of Holders of such
Securities to receive, solely from the trust fund described in Section 1304 and
as more fully set forth in such Section, payments in respect of the principal
of and any premium and interest on such Securities when payments are due, (2)
the Company's obligations with respect to such Securities under Sections 304,
305, 306, 1002 and 1003, (3) the rights, powers, trusts, duties and immunities
of the Trustee hereunder and (4) this Article. Subject to compliance with this
Article, the Company may exercise its option (if any) to have this Section
applied to any Securities notwithstanding the prior exercise of its option (if
any) to have Section 1303 applied to such Securities.


SECTION 1303.  Covenant Defeasance.

      Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, (1)
the Company shall be released from its obligations under Section 801(3),
Sections 1006 through 1009, inclusive, and any covenants provided pursuant to
Section 301(18), 901(2) or 901(7) for the benefit of the Holders of such
Securities and (2) the occurrence of any event specified in Sections 501(4)
(with respect to any of Section 801(3), Sections 1006 through 1009,





                                     -62-
<PAGE>   71
inclusive, and any such covenants provided pursuant to Section 301(18), 901(2)
or 901(7)), 501(5) and 501(8) shall be deemed not to be or result in an Event
of Default, in each case with respect to such Securities as provided in this
Section on and after the date the conditions set forth in Section 1304 are
satisfied (hereinafter called "Covenant Defeasance"). For this purpose, such
Covenant Defeasance means that, with respect to such Securities, the Company
may omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such specified Section (to the extent
so specified in the case of Section 501(4)), whether directly or indirectly by
reason of any reference elsewhere herein to any such Section or by reason of
any reference in any such Section to any other provision herein or in any other
document, but the remainder of this Indenture and such Securities shall be
unaffected thereby.

SECTION 1304.  Conditions to Defeasance or Covenant Defeasance.

      The following shall be the conditions to the application of Section 1302
or Section 1303 to any Securities or any series of Securities, as the case may
be:

      (1)  The Company shall irrevocably have deposited or caused to be
   deposited with the Trustee (or another trustee which satisfies the
   requirements contemplated by Section 609 and agrees to comply with the
   provisions of this Indenture applicable to it as if it were the Trustee
   hereunder) as trust funds in trust for the purpose of making the following
   payments, specifically pledged as security for, and dedicated solely to, the
   benefits of the Holders of such Securities, (A) in the case Securities
   denominated in a foreign currency, money in such foreign currency or Foreign
   Government Obligations of the foreign government or governments issuing such
   foreign currency which through the scheduled payment of principal and
   interest in respect thereof in accordance with their terms will provide, not
   later than one day before the due date of any payment, such foreign currency
   in an amount or (B) in the case of Securities denominated in U.S. dollars,
   U.S. dollars or U.S. Government Obligations which through the scheduled
   payment of principal and interest in respect thereof in accordance with
   their terms will provide, not later than one day before the due date of any
   payment, U.S. dollars in an amount, or (C) a combination of money and U.S.
   Government Obligations or Foreign Government Obligations (as applicable), in
   each case sufficient, in the opinion of a nationally recognized firm of
   independent public accountants expressed in a written certification thereof
   delivered to the Trustee, to pay and discharge, and which shall be applied
   by the Trustee (or any such other qualifying trustee) to pay and discharge,
   the principal of and any premium and interest on such Securities on the
   respective Stated Maturities, in accordance with the terms of this Indenture
   and such Securities. As used herein, "U.S. Government Obligation" means (x)
   any security which is (i) a direct obligation of the United States of
   America for the payment of which the full faith and credit of the United
   States of America is pledged or (ii) an obligation of a Person controlled or
   supervised by and acting as an agency or instrumentality of the United
   States of America the payment of which is unconditionally guaranteed as a
   full faith and credit obligation by the United States of America, which, in
   either case (i) or (ii), is not callable or redeemable at the option of the
   issuer thereof, and (y) any depositary receipt issued by a bank (as defined
   in





                                     -63-
<PAGE>   72
   Section 3(a)(2) of the Securities Act) as custodian with respect to any U.S.
   Government Obligation which is specified in Clause (x) above and held by
   such bank for the account of the holder of such depositary receipt, or with
   respect to any specific payment of principal of or interest on any U.S.
   Government Obligation which is so specified and held, provided that (except
   as required by law) such custodian is not authorized to make any deduction
   from the amount payable to the holder of such depositary receipt from any
   amount received by the custodian in respect of the U.S. Government
   Obligation or the specific payment of principal or interest evidenced by
   such depositary receipt.  As used herein, "Foreign Government Obligation"
   means any security denominated in a foreign currency which is (i) a direct
   obligation of a foreign government or governments for the payment of which
   the full faith and credit of such foreign government or governments is
   pledged or (ii) an obligation of a Person controlled or supervised by and
   acting as an agency or instrumentality of such foreign government or
   governments the payment of which is unconditionally guaranteed as a full
   faith and credit obligation by such foreign government, which, in either
   case (i) or (ii) is not callable or redeemable at the option of the issuer
   thereof.

      (2)  In the event of an election to have Section 1302 apply to any
   Securities or any series of Securities, as the case may be, the Company
   shall have delivered to the Trustee an Opinion of Counsel stating that
   (A)(x) the Company has received from, or there has been published by, the
   Internal Revenue Service a ruling or (y) since the date of this instrument,
   there has been a change in the applicable Federal income tax law, in either
   case (x) or (y) to the effect that, and based thereon such opinion shall
   confirm that, the Holders of such Securities will not recognize gain or loss
   for Federal income tax purposes as a result of the deposit, Defeasance and
   discharge to be effected with respect to such Securities and will be subject
   to Federal income tax on the same amount, in the same manner and at the same
   times as would be the case if such deposit, Defeasance and discharge were
   not to occur and (B) if Securities of such series Securities are then listed
   on the New York Stock Exchange to the effect that the Securities of such
   series will not be delisted as a result of such election.

      (3)  In the event of an election to have Section 1303 apply to any
   Securities or any series of Securities, as the case may be, the Company
   shall have delivered to the Trustee an Opinion of Counsel to the effect that
   the Holders of such Securities will not recognize gain or loss for Federal
   income tax purposes as a result of the deposit and Covenant Defeasance to be
   effected with respect to such Securities and will be subject to Federal
   income tax on the same amount, in the same manner and at the same times as
   would be the case if such deposit and Covenant Defeasance were not to occur.

      (4)  The Company shall have delivered to the Trustee an Officer's
   Certificate to the effect that neither such Securities nor any other
   Securities of the same series, if then listed on any securities exchange,
   will be delisted as a result of such deposit.


      (5)  No event which is, or after notice or lapse of time or both would
   become, a Default with respect to such Securities or any other Securities
   shall have occurred and be continuing at the time of such deposit or, with
   regard to any such event specified in Sections 501(6) and (7), at any time
   on or prior to the 90th day after the date of





                                     -64-
<PAGE>   73
   such deposit or, if longer, ending on the day following the expiration of
   the longest preference period applicable to the Company under Federal or
   State law in respect of such deposit (it being understood that this
   condition shall not be deemed satisfied until after the expiration of such
   period).

      (6)  Such Defeasance or Covenant Defeasance shall not cause the Trustee
   to have a conflicting interest within the meaning of the Trust Indenture Act
   (assuming all Securities are in default within the meaning of such Act).

      (7)  Such Defeasance or Covenant Defeasance shall not result in a breach
   or violation of, or constitute a default under, any other agreement or
   instrument to which the Company is a party or by which it is bound.

      (8)  Such Defeasance or Covenant Defeasance shall not result in the trust
   arising from such deposit constituting an investment company within the
   meaning of the Investment Company Act unless such trust shall be registered
   under such Act or exempt from registration thereunder.

      (9)   The Company shall have delivered to the Trustee an Officer's
   Certificate and an Opinion of Counsel, each stating that all conditions
   precedent with respect to such Defeasance or Covenant Defeasance have been
   complied with.


SECTION 1305.  Deposited Money and U.S. Government Obligations to Be
   Held in Trust; Miscellaneous Provisions.

      Subject to the provisions of the last paragraph of Section 1003, all
money, U.S. Government Obligations and Foreign Government Obligations 
(including the proceeds thereof) deposited with the Trustee or other 
qualifying trustee (solely for purposes of this Section and Section 1306, the 
Trustee and any such other trustee are referred to collectively as the 
"Trustee") pursuant to Section 1304 in respect of any Securities shall be held 
in trust and applied by the Trustee, in accordance with the provisions of such 
Securities and this Indenture, to the payment, either directly or through any 
such Paying Agent (including the Company acting as its own Paying Agent) as 
the Trustee may determine, to the Holders of such Securities, of all sums due 
and to become due thereon in respect of principal and any premium and interest, 
but money so held in trust need not be segregated from other funds except to 
the extent required by law.

      The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S.  Government Obligations
or Foreign Government Obligations deposited pursuant to Section 1304 or the 
principal and interest received in respect thereof other than any such tax, 
fee or other charge which by law is for the account of the Holders of 
Outstanding Securities.

      Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or U.S. Government Obligations or Foreign Government Obligations held by
it as provided in Section 1304 with respect to any





                                     -65-
<PAGE>   74
Securities which, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to
the Trustee, are in excess of the amount thereof which would then be required
to be deposited to effect the Defeasance or Covenant Defeasance, as the case
may be, with respect to such Securities.


SECTION 1306.  Reinstatement.

      If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 1302 or 1303 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to
apply all money held in trust pursuant to Section 1305 with respect to such
Securities in accordance with this Article; provided, however, that if the
Company makes any payment of principal of or any premium or interest on any
such Security following such reinstatement of its obligations, the Company
shall be subrogated to the rights (if any) of the Holders of such Securities to
receive such payment from the money so held in trust.

such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

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

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


SECTION 104.  Acts of Holders; Record Dates.

      Any request, demand, authorization, direction, notice, consent, waiver or
other action provided or permitted by this Indenture to be given, made or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

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

      The ownership of Securities shall be proved by the Security Register.

      Without limiting the generality of the foregoing, a Holder, including a
Depositary that is a Holder of a Global Security, may make, give or take, by
proxy or proxies, duly appointed in writing, any request, demand,
authorization, direction, notice, consent,





                                      -10-
<PAGE>   21
waiver or other action provided or permitted in this Indenture to be made,
given or taken by Holders, and a Depositary that is a Holder of a Global
Security may provide its proxy or proxies to the beneficial owners of interests
in any such Global Security.

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

      The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series, provided that the
Company may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in the next paragraph. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders
remain Holders after such record date; provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
by Holders of the requisite principal amount of Outstanding Securities of such
series on such record date. Nothing in this paragraph shall be construed to
prevent the Company from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be cancelled and of no effect), and nothing in this paragraph shall be
construed to render ineffective any action taken by Holders of the requisite
principal amount of Outstanding Securities of the relevant series on the date
such action is taken. Promptly after any record date is set pursuant to this
paragraph, the Company, at its own expense, shall cause notice of such record
date, the proposed action by Holders and the applicable Expiration Date to be
given to the Trustee in writing and to each Holder of Securities of the
relevant series in the manner set forth in Section 106.

      The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
join in the giving or making of (i) any Notice of Default, (ii) any declaration
of acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred to in
Section 512, in each case with respect to Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date; provided that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this





                                      -11-
<PAGE>   22
paragraph shall be construed to prevent the Trustee from setting a new record
date for any action for which a record date has previously been set pursuant to
this paragraph (whereupon the record date previously set shall automatically
and with no action by any Person be cancelled and of no effect), and nothing in
this paragraph shall be construed to render ineffective any action taken by
Holders of the requisite principal amount of Outstanding Securities of the
relevant series on the date such action is taken. Promptly after any record
date is set pursuant to this paragraph, the Trustee, at the Company's expense,
shall cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Company in writing and to each
Holder of Securities of the relevant series in the manner set forth in Section
106.

      With respect to any record date set pursuant to this Section, the party
hereto which sets such record dates may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day; provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Securities of the relevant series in the manner set forth in
Section 106, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

      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.


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

      Any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with,

         (1)  the Trustee by any Holder or by the Company shall be sufficient
   for every purpose hereunder if made, given, furnished or filed in writing to
   or with the Trustee at its Corporate Trust Office, Attention: Corporate
   Trust Administration, or

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

<PAGE>   23
SECTION 106.  Notice to Holders; Waiver.

      Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice. In any case where notice to Holders
is given by mail, neither the failure to mail such notice, nor any defect in
any notice so mailed, to any particular Holder shall affect the sufficiency of
such notice with respect to other Holders. Where this Indenture provides for
notice in any manner, such notice may be waived in writing by the Person
entitled to receive such notice, either before or after the event, and such
waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

      In case by reason of the suspension of regular mail service or by reason
of any other cause it shall be impracticable to give such notice by mail, then
such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.


SECTION 107.  Conflict with Trust Indenture Act.

      If any provision hereof limits, qualifies or conflicts with a provision
of the Trust Indenture Act which is required under such Act to be a part of and
govern this Indenture, the latter provision shall control. If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
which may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be.


SECTION 108.  Effect of Headings and Table of Contents.

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


SECTION 109.  Successors and Assigns.

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

SECTION 110.  Separability Clause.

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


SECTION 111.  Benefits of Indenture.

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


SECTION 112.  Governing Law.

      This Indenture and the Securities shall be governed by and construed in
accordance with the law of the State of New York.


SECTION 113.  Legal Holidays.

      In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security or the last date on which a Holder has the right to
convert his Securities shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the
Securities (other than a provision of any Security which specifically states
that such provision shall apply in lieu of this Section)) payment of interest
or principal (and premium, if any) or conversion of the Securities need not be
made at such Place of Payment on such date, but may be made on the next
succeeding Business Day at such Place of Payment with the same force and effect
as if made on the Interest Payment Date or Redemption Date, or at the Stated
Maturity or on such last day for conversion.

and other variations as are required or

registered at the close of business on a Special Record Date for the payment of

SECTION 203.  Form of Reverse of Security.

      This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or
more series under an Indenture, dated as of ............... (herein called the
"Indenture", which term shall have the meaning assigned to it in such
instrument), between the Company and ..................., as Trustee (herein
called the "Trustee", which term includes any successor trustee under the
Indenture), and reference is hereby made to the Indenture for a statement of
the respective rights, limitations of rights, duties and immunities thereunder
of the Company, the Trustee, the holders of Senior Indebtedness, Entitled





                                      -17-

Persons, and the Holders of the Securities and of the terms upon which the
Securities are, and are to be, authenticated and delivered. This Security is
one of the series designated on the face hereof.

      [If applicable, insert -- The Securities of this series are subject to
redemption upon not less than 30 days' notice by mail, [if applicable, insert
- -- (1) on ........... in any year commencing with the year ...... and ending
with the year ...... through operation of the sinking fund for this series at a
Redemption Price equal to 100% of the principal amount, and (2)] at any time
[if applicable, insert -- on or after .........., 19..], as a whole or in part,
at the election of the Company, at the following Redemption Prices (expressed
as percentages of the principal amount): If redeemed [if applicable, insert --
on or before ..............., ...%, and if redeemed] during the 12-month period
beginning ............. of the years indicated,

and thereafter at a Redemption Price equal to .....% of the principal amount,
together in the case of any such redemption [if applicable, insert -- (whether
through operation of the sinking fund or otherwise)] with accrued interest to
the Redemption Date, but interest instalments whose Stated Maturity is on or
prior to such Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, of record at the close of
business on the relevant Record Dates referred to on the face hereof, all as
provided in the Indenture.]

      [If applicable, insert --  Subject to and in compliance with the
provisions of the Indenture, the Holder of this Security is entitled, at his
option, at any time on or after the opening of business on the Initial
Conversion Date and on or before the close of business on the Final Conversion
Date, or in case this Security or a portion hereof is called for redemption,
then in respect of this Security or such portion hereof until and including,
but (unless the Company defaults in making the payment due upon redemption) not
after, the close of business on the Redemption Date, to convert this Security
(or any portion of the principal amount hereof which is $1,000 or an integral
multiple thereof), at the principal amount hereof, or of such portion, into
fully paid and non-assessable shares (calculated as to each conversion to the
nearest 1/100 of a share) of Common Stock of the Company at the Initial
Conversion Price (or at the current adjusted





                                     -18-
<PAGE>   29
conversion price if an adjustment has been made as provided in the Indenture)
by surrender of this Security, duly endorsed or assigned to the Company or in
blank, to the Company at its office or agency in the Borough of Manhattan, The
City of New York, accompanied by written notice to the Company that the Holder
hereof elects to convert this Security, or if less than the entire principal
amount hereof is to be converted, the portion hereof to be converted, and, in
case such surrender shall be made during the period from the close of business
on any Regular Record Date next preceding any Interest Payment Date (unless
this Security or the portion thereof being converted has been called for
redemption on a Redemption Date within such period), also accompanied by
payment in New York Clearing House or other funds acceptable to the Company of
an amount equal to the interest payable on such Interest Payment Date on the
principal amount of this Security then being converted.  Subject to the
aforesaid requirement for payment in the case of a conversion after the Regular
Record Date next preceding any Interest Payment Date and on or before such
Interest Payment Date, to the right of the Holder of this Security (or any
Predecessor Security) of record at such Regular Record Date to receive an
installment of interest (with certain exceptions provided in the Indenture), no
payment or adjustment is to be made on conversion for interest accrued hereon
or for dividends on the Common Stock issued on conversion.  No fractions of
shares or scrip representing fractions of shares will be issued on conversion,
but instead of any fractional interest the Company shall pay a cash adjustment
as provided in the Indenture.  The conversion price is subject to adjustment as
provided in the Indenture.  In addition, the Indenture provides that in case of
certain consolidations or mergers to which the Company is a party or the
transfer of substantially all of the assets of the Company, the Indenture shall
be amended, without the consent of any Holders of Securities, so that this
Security, if then outstanding, will be convertible thereafter, during the
period this Security shall be convertible as specified above, only into the
kind and amount of securities, cash and other property receivable upon the
consolidation, merger or transfer by a holder of the number of shares of Common
Stock into which this Security might have been converted immediately prior to
such consolidation, merger or transfer (assuming such holder of Common Stock
failed to exercise any rights of election and received per share the kind and
amount received per share by a plurality of non-electing shares), assuming, if
such consolidation, merger or transfer is prior to the Initial Conversion Date,
that is Security were convertible at the time of such consolidation, merger or
transfer at the Initial Conversion Price specified above as adjusted from the
date of establishment of the Initial Conversion Price to such time pursuant to
the Indenture.]

      [If applicable, insert -- The Securities of this series are subject to
redemption upon not less than 30 days' notice by mail, (1) on ............ in
any year commencing with the year .... and ending with the year .... through
operation of the sinking fund for this series at the Redemption Prices for
redemption through operation of the sinking fund (expressed as percentages of
the principal amount) set forth in the table below, and (2) at any time [if
applicable, insert -- on or after ............], as a whole or in part, at the
election of the Company, at the Redemption Prices for redemption otherwise than

principal amount) set forth

interest instalments whose Stated Maturity is on or prior to such Redemption
Date will be payable to the Holders of such Securities, or one or more
Predecessor Securities, of record at the close of business on the relevant
Record Dates referred to on the face hereof, all as provided in the Indenture.]

not, prior to ............., redeem any Securities of this series as
contemplated by [if applicable, insert -- Clause (2) of] the preceding
paragraph as a part of, or in anticipation of, any refunding operation by the
application, directly or indirectly, of moneys borrowed having an interest cost

the Securities and the payment of principal of (and premium, if any) and
interest on each and all of the Securities are hereby expressly made
subordinate and subject in right of payment to the prior payment in full of all
Senior Indebtedness.  In addition, this Security is also issued subordinate and
subject to the provisions of the Indenture regarding prior payment in full to
Entitled Persons in respect of Other Financial Obligations.  The Indenture also
provides that if, upon the occurrence of certain events of bankruptcy or
insolvency relating to the Company, there remains, after giving effect to such
subordination provisions, any amount of cash, property or securities available
for payment or distribution in respect of Securities of this series (as defined
in the Indenture, "Excess Proceeds"), and if, at such time, any Entitled Person
has not received payment in full of all amounts due or to become due on or in
respect of Other Financial Obligations, then such Excess Proceeds shall first
be applied to pay or provide for the payment in full of such Other Financial
Obligations before any payment or distribution may be made in respect of
Securities of such series.  Each Holder of this Security, by accepting the
same, (a) agrees to and shall be bound by such provisions, (b) authorizes and
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination and payment of Excess Proceeds as
provided in the Indenture and (c) appoints the Trustee his attorney-in-fact for
any and all such purposes.

Security] [, in each case] upon compliance with certain conditions set forth in
the Indenture.]

      [If the Security is not an Original Issue Discount Security, insert -- If
an Event of Default with respect to Securities of this series shall occur and
be continuing, the principal of the Securities of this series may be declared
due and payable in the manner and with the effect provided in the Indenture.]

      [If the Security is an Original Issue Discount Security, insert -- If an
Event of Default with respect to Securities of this series shall occur and be
continuing, an amount of principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture.  Such amount shall be equal to -- insert formula for determining the
amount.  Upon payment (i) of the amount of principal so declared due and
payable and (ii) of interest on any overdue principal, premium and interest (in
each case to the extent that the payment of such interest shall be legally
enforceable), all of the Company's obligations in respect of the payment of the
principal of and premium and interest, if any, on the Securities of this series
shall terminate.]

amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with
the consent of the Holders of 66 2/3% in principal amount of the Securities at
the time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

      As provided in and subject to the provisions of the Indenture, the Holder
of this Security shall not have the right to institute any proceeding with
respect to the Indenture or for the appointment of a receiver or trustee or for
any other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made
written request to the Trustee to institute proceedings in respect of such
Event of Default as Trustee and offered the Trustee reasonable indemnity, and
the Trustee shall not have received from the Holders of a majority in principal
amount of Securities of this series at the time Outstanding a direction
inconsistent with such request, and shall have failed to institute any such
proceeding, for 60 days after receipt of such notice, request and offer of
indemnity. The foregoing shall not apply to any suit instituted by the Holder
of this Security for the enforcement of any payment of principal hereof or any
premium or interest hereon on or after the respective due dates expressed
herein.

      No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any premium and
interest on this Security at the times, place and rate, and in the coin or
currency, herein prescribed [if applicable, insert - or to convert this
Security as provided in the Indenture.]

      As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in any place where the principal of and any
premium and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Securities
of this series and of like tenor, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

<PAGE>   38
      At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series executed by
the Company to the Trustee for authentication, together with a Company Order
for the authentication and delivery of such Securities, and the Trustee in
accordance with the Company Order shall authenticate and deliver such
Securities. If the form or terms of the Securities of the series have been
established by or pursuant to one or more Board Resolutions as permitted by
Sections 201 and 301, in authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such
Securities, the Trustee shall be entitled to receive, and (subject to Section
601) shall be fully protected in relying upon, an Opinion of Counsel stating,

       (1) if the form of such Securities has been established by or pursuant
   to Board Resolution as permitted by Section 201, that such form has been
   established in conformity with the provisions of this Indenture;

       (2) if the terms of such Securities have been established by or pursuant
   to Board Resolution as permitted by Section 301, that such terms have been
   established in conformity with the provisions of this Indenture; and

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

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

      Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the
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.

      Each Security shall be dated the date of its authentication.

      No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered





                                      -28-

hereunder. Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 309, for all purposes of this Indenture such Security shall
be deemed never to have been authenticated and delivered hereunder and shall
never be entitled to the benefits of this Indenture.


SECTION 304.  Temporary Securities.

      Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

      If temporary Securities of any series are issued, the Company will cause
definitive Securities of that series to be prepared without unreasonable delay.
After the preparation of definitive Securities of such series, the temporary
Securities of such series shall be exchangeable for definitive Securities of
such series upon surrender of the temporary Securities of such series at the
office or agency of the Company in a Place of Payment for that series, without
charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities of any series, the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor one or more definitive
Securities of the same series, of any authorized denominations and of like
tenor and aggregate principal amount. 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 and tenor.


SECTION 305.  Registration, Registration of Transfer and Exchange.

      The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is
hereby appointed "Security Registrar" for the purpose of registering Securities
and transfers of Securities as herein provided.

      Upon surrender for registration of transfer of any Security of a series
at the office or agency of the Company in a Place of Payment for that series,
the Company shall execute, and the Trustee shall authenticate and deliver, in
the name of the designated





                                      -29-
<PAGE>   40
transferee or transferees, one or more new Securities of the same series, of
any authorized denominations and of like tenor and aggregate principal amount.

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

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

      Every Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Company or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

      No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

      If the Securities of any series (or of any series and specified tenor)
are to be redeemed in part, the Company shall not be required (A) to issue,
register the transfer of or exchange any Securities of that series (or of that
series and specified tenor, as the case may be) during a period beginning at
the opening of business 15 days before the day of the mailing of a notice of
redemption of any such Securities selected for redemption under Section 1103
and ending at the close of business on the day of such mailing, or (B) to
register the transfer of or exchange any Security so selected for redemption in
whole or in part, except the unredeemed portion of any Security being redeemed
in part.

      The provisions of Clauses (1), (2), (3) and (4) below shall apply only to
Global Securities:

       (1) Each Global Security authenticated under this Indenture shall be
   registered in the name of the Depositary designated for such Global Security
   or a nominee thereof and delivered to such Depositary or a nominee thereof
   or custodian therefor, and each such Global Security shall constitute a
   single Security for all purposes of this Indenture.





                                      -30-
<PAGE>   41
       (2) Notwithstanding any other provision in this Indenture, no Global
   Security may be exchanged in whole or in part for Securities registered, and
   no transfer of a Global Security in whole or in part may be registered, in
   the name of any Person other than the Depositary for such Global Security or
   a nominee thereof unless (A) such Depositary (i) has notified the Company
   that it is unwilling or unable to continue as Depositary for such Global
   Security and no Successor Depositary has been appointed within 90 days or
   (ii) has ceased to be a clearing agency registered under the Exchange Act,
   (B) there shall have occurred and be continuing an Event of Default with
   respect to such Global Security, (C) the Company, in its sole discretion,
   has determined that Securities of any series issued in the form of one or
   more Global Securities shall no longer be represented by such Global
   Security or Global Securities or (D) there shall exist such circumstances,
   if any, in addition to or in lieu of the foregoing as have been specified
   for this purpose as contemplated by Section 301.

       (3) Subject to Clause (2) above, any exchange of a Global Security for
   other Securities may be made in whole or in part, and all Securities issued
   in exchange for a Global Security or any portion thereof shall be registered
   in such names as the Depositary for such Global Security shall direct.

       (4) Every Security authenticated and delivered upon registration of
   transfer of, or in exchange for or in lieu of, a Global Security or any
   portion thereof, whether pursuant to this Section, Section 304, 306, 906 or
   1107 or otherwise, shall be authenticated and delivered in the form of, and
   shall be, a Global Security, unless such Security is registered in the name
   of a Person other than the Depositary for such Global Security or a nominee
   thereof.


SECTION 306.  Mutilated, Destroyed, Lost and Stolen Securities.

      If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

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

      In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.





                                      -31-
<PAGE>   42
      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 issued pursuant to this Section in lieu
of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall
be entitled to all the benefits of this Indenture equally and proportionately
with any and all other Securities of that series duly issued hereunder.

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


SECTION 307.  Payment of Interest; Interest Rights Preserved.

      Except as otherwise provided as contemplated by Section 301 with respect
to any series of Securities, interest on any Security which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date shall be
paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

      Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:

         (1)  The Company may elect to make payment of any Defaulted Interest
      to the Persons in whose names the Securities of such series (or their
      respective Predecessor Securities) are registered at the close of
      business on a Special Record Date for the payment of such Defaulted
      Interest, which shall be fixed in the following manner. The Company shall
      notify the Trustee in writing of the amount of Defaulted Interest
      proposed to be paid on each Security of such series and the date of the
      proposed payment, and at the same time the Company shall deposit with the
      Trustee an amount of money equal to the aggregate amount proposed to be
      paid in respect of such Defaulted Interest or shall make arrangements
      satisfactory to the Trustee for such deposit prior to the date of the
      proposed payment, such money when deposited to be held in trust for the
      benefit of the Persons entitled to such Defaulted Interest as in this
      Clause provided. Thereupon the Trustee shall fix a Special Record Date
      for the payment of such Defaulted Interest which shall be not more than
      15 days and not less than 10 days prior to the date of the proposed
      payment and not less than 10 days after the receipt by the Trustee of the
      notice of





                                      -32-
<PAGE>   43
   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 given to each Holder of Securities of
   such series in the manner set forth in Section 106, not less than 10 days
   prior to such Special Record Date. Notice of the proposed payment of such
   Defaulted Interest and the Special Record Date therefor having been so
   mailed, such Defaulted Interest shall be paid to the Persons in whose names
   the Securities of such series (or their respective Predecessor Securities)
   are registered at the close of business on such Special Record Date and
   shall no longer be payable pursuant to the following Clause (2).

         (2)  The Company may make payment of any Defaulted Interest on the
   Securities of any series in any other lawful manner not inconsistent with
   the requirements of any securities exchange on which such Securities may
   be listed, and upon such notice as may be required by such exchange, if,
   after notice given by the Company to the Trustee of the proposed payment
   pursuant to this Clause, such manner of payment shall be deemed
   practicable by the Trustee.

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

      In the case of any convertible Security which is converted after any
Regular Record Date and on or prior to the next succeeding Interest Payment
Date (other than any Security whose Maturity is prior to such Interest Payment
Date), interest whose Stated Maturity is on such Interest Payment Date shall be
payable on such Interest Payment Date notwithstanding such conversion, and such
interest (whether or not punctually paid or duly provided for) shall be paid to
the Person in whose name that Security (or one or more Predecessor Securities)
is registered at the close of business on such Regular Record Date.  Except as
otherwise expressly provided in the immediately preceding sentence, in the case
of any convertible Security which is converted, interest whose Stated Maturity
is after the date of conversion of such Security shall not be payable.


SECTION 308.  Persons Deemed Owners.

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





                                      -33-
<PAGE>   44
SECTION 309.  Cancellation.

      All Securities surrendered for payment, redemption, registration of
transfer or exchange or conversion or for credit against any sinking fund
payment shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee and shall be promptly cancelled by it. The Company may
at any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in
any manner whatsoever, and may deliver to the Trustee (or to any other Person
for delivery to the Trustee) for cancellation any Securities previously
authenticated hereunder which the Company has not issued and sold, and all
Securities so delivered shall be promptly cancelled by the Trustee. No
Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section, except as expressly permitted by this
Indenture. All cancelled Securities held by the Trustee shall be disposed of as
directed by a Company Order.


SECTION 310.  Computation of Interest.

      Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

                          SATISFACTION AND DISCHARGE


SECTION 401.  Satisfaction and Discharge of Indenture.

      This Indenture shall upon Company Request cease to be of further effect
(except as to any surviving rights of conversion, registration of transfer or
exchange of Securities herein expressly provided for), and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

      (1)  either

         (A)  all Securities theretofore authenticated and delivered (other
      than (i) Securities which have been destroyed, lost or stolen and which
      have been replaced or paid as provided in Section 306 and (ii) Securities
      for whose payment money has theretofore been deposited in trust or
      segregated and held in trust by the Company and thereafter repaid to the
      Company or discharged from such trust, as provided in Section 1003) have
      been delivered to the Trustee for cancellation; or

         (B)  all such Securities not theretofore delivered to the Trustee for
      cancellation





                                      -34-
<PAGE>   45
            (i)  have become due and payable, or

           (ii)  will become due and payable at their Stated Maturity within 
         one year, or

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

      and the Company, in the case of (i), (ii) or (iii) above, has deposited
      or caused to be deposited with the Trustee as trust funds in trust for
      the purpose money in an amount sufficient to pay and discharge the entire
      indebtedness on such Securities not theretofore delivered to the Trustee
      for cancellation, for principal and any premium and interest to the date
      of such deposit (in the case of Securities which have become due and
      payable) or to the Stated Maturity or Redemption Date, as the case may
      be;

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

      (3)  the Company has delivered to the Trustee an Officers' Certificate
   and an Opinion of Counsel, each stating that all conditions precedent herein
   provided for relating to the satisfaction and discharge of this Indenture
   have been complied with.

      Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of
this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.


SECTION 402.  Application of Trust Money.

      Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium
and interest for whose payment such money has been deposited with the Trustee.
Money deposited and held in trust pursuant to this Section 402 shall not be
subject to claims of the holders of Senior Indebtedness or of Entitled Persons
under Article Fourteen. All moneys deposited with the Trustee pursuant to
Section 401 (and held by it or the Paying Agent) for the payment of Securities
subsequently converted shall be returned to the Company upon Company Request.

SECTION 501.  Events of Default.

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

      (1)  the entry by a court or governmental authority having jurisdiction
   in the premises of (A) a decree or order for relief in respect of the
   Company in an involuntary case or proceeding under any applicable Federal or
   State bankruptcy, insolvency, reorganization or other similar law or (B) a
   decree or order adjudging the Company a bankrupt or insolvent, or approving
   as properly filed a petition seeking reorganization, arrangement, adjustment
   or composition of or in respect of the Company under any applicable Federal
   or State law, or appointing a custodian, receiver, liquidator, assignee,
   trustee, sequestrator or other similar official of the Company or of any
   substantial part of its property (other than a conservator or other similar
   official in respect of a Bank), or ordering the winding up or liquidation of
   its affairs, and the continuance of any such decree or order for relief or
   any such other decree or order unstayed and in effect for a period of 60
   consecutive days; or

      (2)  the commencement by the Company of a voluntary case or proceeding
   under any applicable Federal or State bankruptcy, insolvency, reorganization
   or other similar law or of any other case or proceeding to be adjudicated a
   bankrupt or insolvent, or the consent by it to the entry of a decree or
   order for relief in respect of the Company in an involuntary case or
   proceeding under any applicable Federal or State bankruptcy, insolvency,
   reorganization or other similar law or to the commencement of any bankruptcy
   or insolvency case or proceeding against it, or the filing by it of a
   petition or answer or consent seeking reorganization or relief under any
   applicable Federal or State law, or the consent by it to the filing of such
   petition or to the appointment of or taking possession by a custodian,
   receiver, liquidator, assignee, trustee, sequestrator or other similar
   official of the Company or of any substantial part of its property (other
   than a conservator or other similar official in respect of a Bank), or the
   making by it of an assignment for the benefit of creditors, or the admission
   by it in writing of its inability to pay its debts generally as they become
   due, or the taking of corporate action by the Company in furtherance of any
   such action; or

      (3)  any other Event of Default provided with respect to Securities of
   that series.





                                      -36-
<PAGE>   47
SECTION 502.  Acceleration of Maturity; Rescission and Annulment.

      If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then in every such case the Trustee
or the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series may declare the principal amount of all the
Securities of that series (or, if any Securities of that series are Original
Issue Discount Securities, such portion of the principal amount of such
Securities as may be specified by the terms thereof) to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal amount (or specified
amount) shall become immediately due and payable.

      At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in
this Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if

     (1)  the Company has paid or deposited with the Trustee a sum sufficient 
   to pay

         (A)  all overdue interest on all Securities of that series,

         (B)  the principal of (and premium, if any, on) any Securities of that
      series which have become due otherwise than by such declaration of
      acceleration and any interest thereon at the rate or rates prescribed
      therefor in such Securities,

         (C)  to the extent that payment of such interest is lawful, interest
      upon overdue interest at the rate or rates prescribed therefor in such
      Securities, and

         (D)  all sums paid or advanced by the Trustee hereunder and the
      reasonable compensation, expenses, disbursements and advances of the
      Trustee, its agents and counsel;

   and

     (2)  all 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 513.

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

SECTION 503.  Collection of Indebtedness and Suits for Enforcement by Trustee.

      The Company covenants that if

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

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

      (3)  default is made in the making or satisfaction of any sinking fund
   payment or analogous obligation when the same becomes due pursuant to the
   terms of such Security,

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

      If the Company shall fail to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute
a judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Security or 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.

      "Default", wherever used herein with respect to Securities of any series,
means any one of the following events (whatever the reason for such Default and
whether it shall be occasioned by the provisions of Article Fourteen or be
voluntary or involuntary or be effected by operation of law or pursuant to any
judgment, decree or order of any court or governmental body);

         (A)  an Event of Default with respect to any Securities of that
      series; or

         (B)  the events referred to in subsections 503(1) through (3) above
      with respect to any Securities of that series; or

         (C)  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





                                      -38-
<PAGE>   49
   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 30 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

         (D)  any other Default provided with respect to Securities of that
   series.

      If a Default with respect to Securities of any series occurs and is
continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series by such
appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy.


SECTION 504.  Trustee May File Proofs of Claim.

      In case of any judicial proceeding relative to the Company (or any other
obligor upon the Securities), its property or its creditors, the Trustee shall
be entitled and empowered, by intervention in such proceeding or otherwise, to
take any and all actions authorized under the Trust Indenture Act in order to
have claims of the Holders and the Trustee allowed in any such proceeding. In
particular, the Trustee shall be authorized to collect and receive any moneys
or other property payable or deliverable on any such claims and to distribute
the same; and any custodian, receiver, assignee, trustee, liquidator,
sequestrator or other similar official in any such judicial proceeding is
hereby authorized by each Holder to make such payments to the Trustee and, in
the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, and any other amounts due the Trustee under Section
607.

      No provision of this Indenture shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding; provided,
however, that the Trustee may, on behalf of the Holders, vote for the election
of a trustee in bankruptcy or similar official and be a member of a creditors'
or other similar committee.

SECTION 505.  Trustee May Enforce Claims Without Possession of Securities.

      All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto,
and any such proceeding instituted by the Trustee shall be brought in its own
name as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.


SECTION 506.  Application of Money Collected.

      Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal or any
premium or interest, upon presentation of the Securities and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

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

    SECOND: Subject to Article Fourteen, to the payment of the amounts then
   due and unpaid for principal of and any premium and interest on the
   Securities in respect of which or for the benefit of which such money has
   been collected, ratably, without preference or priority of any kind,
   according to the amounts due and payable on such Securities for principal
   and any premium and interest, respectively.


SECTION 507.  Limitation on Suits.

      No Holder of any Security of any series shall have any right to institute
any proceeding, judicial or otherwise, with respect to this Indenture, or for
the appointment of a receiver or trustee, or for any other remedy hereunder,
unless

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

      (2)  the Holders of not less than 25% in principal amount of the
   Outstanding Securities of that series shall have made written request to the
   Trustee to institute proceedings in respect of such Default in its own name
   as Trustee hereunder;

      (3)  such Holder or Holders have offered to the Trustee reasonable
   indemnity against the costs, expenses and liabilities to be incurred in
   compliance with such request;





                                      -40-
<PAGE>   51
      (4)  the Trustee for 60 days after its receipt of such notice, request
   and offer of indemnity has failed to institute any such proceeding; and

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

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


SECTION 508.  Unconditional Right of Holders to Receive Principal,
   Premium and Interest or to Convert.

      Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of and any premium and (subject to Section 307)
interest on such Security on the respective Stated Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date) and, if
applicable, to convert such Security in accordance with Article Fifteen and to
institute suit for the enforcement of any such payment and right to convert,
and such rights shall not be impaired without the consent of such Holder.


SECTION 509.  Restoration of Rights and Remedies.

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


SECTION 510.  Rights and Remedies Cumulative.

      Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 306, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise.





                                      -41-
<PAGE>   52
The assertion or employment of any right or remedy hereunder, or otherwise,
shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.


SECTION 511.  Delay or Omission Not Waiver.

      No delay or omission of the Trustee or of any Holder of any Securities to
exercise any right or remedy accruing upon any Default shall impair any such
right or remedy or constitute a waiver of any such Default or an acquiescence
therein. Every right and remedy given by this Article or by law to the Trustee
or to the Holders may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the Holders, as the case may be.


SECTION 512.  Control by Holders.

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

      (1)  such direction shall not be in conflict with any rule of law or 
    with this Indenture, and

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


SECTION 513.  Waiver of Past Defaults.

      The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series waive any past default hereunder with respect to such
series and its consequences, except a default

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

      (2)  in respect of a covenant or provision hereof which under Article
    Nine cannot be modified or amended without the consent of the 
    Holder of each Outstanding Security of such series affected.

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

SECTION 514.  Undertaking for Costs.

      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, a court may require any party litigant in such suit
to file an undertaking to pay the costs of such suit, and may assess costs
against any such party litigant, in the manner and to the extent provided in
the Trust Indenture Act; provided that neither this Section nor the Trust
Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the
Company, by such Trustee or by a Holder or group of Holders holding in the 
aggregate more than 10% in principal amount of the Outstanding Securities of 
any series, or to any suit instituted by any Holder for the enforcement of the 
payment of the principal of (or premium, if any) or interest on any Securities 
on or after the Stated Maturity or Maturities expressed in such Securities 
(or, in the case of redemption, on or after the Redemption Date).


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

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


                                  ARTICLE SIX

SECTION 601.  Certain Duties and Responsibilities.

      The duties and responsibilities of the Trustee shall be as provided by
the Trust Indenture Act. Notwithstanding the foregoing, 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.
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.

default as and to the extent provided by the Trust Indenture Act; provided,
however, that in the case of any default of the character specified in Section
503(c) with respect to Securities of such series, no such notice to Holders

   on its part, rely upon an Officers' Certificate;

      (4)  the Trustee may consult with counsel and the written advice of such
   counsel or any Opinion of Counsel shall be full and complete authorization
   and protection in respect of any action taken, suffered or omitted by it
   hereunder in good faith and in reliance thereon;

      (5)  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;

      (6)  the Trustee shall not be bound to make any investigation into the
   facts or matters stated in any resolution, certificate, statement,
   instrument, opinion, report, notice, request, direction, consent, order,
   bond, debenture, note, other evidence of indebtedness or other paper or
   document, but the Trustee, in its discretion, may make





                                      -44-
<PAGE>   55
   such further inquiry or investigation into such facts or matters as it may
   see fit, and, if the Trustee shall determine to make such further inquiry or
   investigation, it shall be entitled to examine the books, records and
   premises of the Company, personally or by agent or attorney; and

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


SECTION 604.  Not Responsible for Recitals or Issuance of Securities.

      The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the
Company, and neither the Trustee nor any Authenticating Agent assumes any
responsibility for their correctness. The Trustee makes no representations as
to the validity or sufficiency of this Indenture or of the Securities. Neither
the Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Company of Securities or the proceeds thereof.


SECTION 605.  May Hold Securities.

      The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to
Sections 608 and 613, may otherwise deal with the Company with the same rights
it would have if it were not Trustee, Authenticating Agent, Paying Agent,
Security Registrar or such other agent.


SECTION 606.  Money Held in Trust.

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


SECTION 607.  Compensation and Reimbursement.

      The Company agrees

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





                                      -45-
<PAGE>   56
      (2)  except as otherwise expressly provided herein, to reimburse the
   Trustee upon its request for all reasonable expenses, disbursements and
   advances incurred or made by the Trustee in accordance with any provision of
   this Indenture (including the reasonable compensation and the expenses and
   disbursements of its agents and counsel), except any such expense,
   disbursement or advance as may be attributable to its negligence or bad
   faith; and

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


SECTION 608.  Conflicting Interests.

      If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
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 such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series.


SECTION 609.  Corporate Trustee Required; Eligibility.

      There shall at all times be one (and only one) Trustee hereunder with
respect to the Securities of each series, which may be Trustee hereunder for
Securities of one or more other series.  Each Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such, and has a combined
capital and surplus of at least $50,000,000 and has its Corporate Trust Office
or agency in the Borough of Manhattan, The City of New York. If any such 
Person publishes reports of condition at least annually, pursuant to law or to 
the requirements of its supervising or examining authority, then for the 
purposes of this Section and to the extent permitted by the Trust Indenture 
Act, the combined capital and surplus of such Person shall be deemed to be its 
combined capital and surplus as set forth in its most recent report of 
condition so published. If at any time the Trustee with respect to the 
Securities of any series shall cease to be eligible in accordance with the 
provisions of this Section, it shall resign immediately in the manner and with 
the effect hereinafter specified in this Article.


SECTION 610.  Resignation and Removal; Appointment of Successor.

      No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.





                                      -46-
<PAGE>   57
      The Trustee may resign at any time with respect to the Securities of one
or more series by giving written notice thereof to the Company.

      The Trustee may be removed at any time with respect to the Securities of
any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the
Company.

      If the instrument of acceptance by a successor Trustee required by
Section 611 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition
any court of competent jurisdiction for the appointment of a successor Trustee
with respect to the Securities of such series.

      If at any time:

      (1)  the Trustee shall fail to comply with Section 608 after written
   request therefor by the Company or by any Holder who has been a bona fide
   Holder of a Security for at least six months, or

      (2)  the Trustee shall cease to be eligible under Section 609 and shall
   fail to resign after written request therefor by the Company or by any such
   Holder, or

      (3)  the Trustee shall become incapable of acting or shall be adjudged a
   bankrupt or insolvent or a receiver of the Trustee or of its property shall
   be appointed or any public officer shall take charge or control of the
   Trustee or of its property or affairs for the purpose of rehabilitation,
   conservation or liquidation,

then, in any such case, (A) the Company by a Board Resolution may remove the
Trustee with respect to all Securities, or (B) subject to Section 514, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

      If the Trustee shall resign, be removed or become incapable of acting, or
if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Company, by a Board Resolution,
shall promptly appoint a successor Trustee or Trustees with respect to the
Securities of that or those series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all
of such series and that at any time there shall be only one Trustee with
respect to the Securities of any particular series) and shall comply with the
applicable requirements of Section 611. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its
acceptance of such appointment in accordance with the applicable requirements





                                      -47-
<PAGE>   58
of Section 611, become the successor Trustee with respect to the Securities of
such series and to that extent supersede the successor Trustee appointed by the
Company. If no successor Trustee with respect to the Securities of any series
shall have been so appointed by the Company or the Holders and accepted
appointment in the manner required by Section 611, any Holder who has been a
bona fide Holder of a Security of such series for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

      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 to all Holders
of Securities of such series in the manner provided in Section 106. Each notice
shall include the name of the successor Trustee with respect to the Securities
of such series and the address of its Corporate Trust Office.


SECTION 611.  Acceptance of Appointment by Successor.

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

      In case of the appointment hereunder of a successor Trustee with respect
to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1)
shall contain such provisions as shall be necessary or desirable to transfer
and confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of
that or those series to which the appointment of such successor Trustee
relates, (2) if the retiring Trustee is not retiring with respect to all
Securities, shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series as to
which the retiring Trustee is not retiring shall continue to be vested in the
retiring Trustee, and (3) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental indenture shall





                                      -48-
<PAGE>   59
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.

      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 the
first or second preceding paragraph, as the case may be.

      No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified and eligible under
this Article.


SECTION 612.  Merger, Conversion, Consolidation or Succession to Business.

      Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.


SECTION 613.  Preferential Collection of Claims Against Company.

      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 the Trust Indenture Act regarding the collection of claims
against the Company (or any such other obligor).





                                      -49-
<PAGE>   60
SECTION 614.  Appointment of Authenticating Agent.

      The Trustee may appoint an Authenticating Agent or Agents with respect to
one or more series of Securities which shall be authorized to act on behalf of
the Trustee to authenticate Securities of such series issued upon original
issue and upon exchange, registration of transfer, partial conversion or
partial redemption thereof or pursuant to Section 306, and Securities so
authenticated shall be entitled to the benefits of this Indenture and shall be
valid and obligatory for all purposes as if authenticated by the Trustee
hereunder. Wherever reference is made in this Indenture to the authentication
and delivery of Securities by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent and a certificate
of authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be acceptable to the Company and shall at all
times be a corporation organized and doing business under the laws of the
United States of America, any State thereof or the District of Columbia,
authorized under such laws to act as Authenticating Agent, having a combined
capital and surplus of not less than $50,000,000 (except that such combined
capital and surplus amount shall not apply to First Chicago Trust Company of
New York) and subject to supervision or examination by Federal or State
authority. If such Authenticating Agent publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined
capital and surplus of such Authenticating Agent shall be deemed to be its
combined capital and surplus as set forth in its most recent report of
condition so published. If at any time an Authenticating Agent shall cease to
be eligible in accordance with the provisions of this Section, such
Authenticating Agent shall resign immediately in the manner and with the effect
specified in this Section.

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

      An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and to the Company. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 106 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. 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





                                      -50-
<PAGE>   61
originally named as an Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section.

      The Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payments, subject to the provisions
of Section 607.

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

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

the Company is merged or to which such conveyance, transfer or lease is made

<PAGE>   65
      (5)  to add to, change or eliminate any of the provisions of this
   Indenture in respect of one or more series of Securities, provided that any
   such addition, change or elimination (A) shall neither (i) apply to any
   Security of any series created prior to the execution of such supplemental
   indenture and entitled to the benefit of such provision nor (ii) modify the
   rights of the Holder of any such Security with respect to such provision or
   (B) shall become effective only when there is no such Security Outstanding;
   or

      (6)  to secure the Securities; or

      (7)  to establish the form or terms of Securities of any series as
   permitted by Sections 201 and 301; or

      (8)  to evidence and provide for the acceptance of appointment hereunder

   necessary to provide for or facilitate the administration of the trusts
   hereunder by more than one Trustee, pursuant to the requirements of Section
   611;

   series in any material respect;

      (10) to make provision with respect to the conversion rights of Holders
   pursuant to the requirements of Section 1512, if applicable; or

      (11) to cure any ambiguity, to correct or supplement any provision herein
   which may be defective or inconsistent with any other provision herein, or
   to make any other provisions with respect to matters or questions arising
   under this Indenture, provided that such action pursuant to this Clause (10)
   shall not adversely affect the interests of the Holders of Securities of any
   series in any material respect.


SECTION 902.  Supplemental Indentures With Consent of Holders.

      With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company, when authorized by a Board Resolution, and the Trustee
may enter into an indenture or indentures supplemental hereto for the purpose
of adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the rights of the
Holders of Securities of such series under this Indenture; provided, however,
that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Security affected thereby,





                                      -55-
<PAGE>   66
      (1)  change the Stated Maturity of the principal of, or any installment of
   principal of or interest on, any Security, or reduce the principal amount
   thereof or the rate of interest thereon or any premium payable upon the
   redemption thereof, or reduce the amount of the principal of an Original
   Issue Discount Security or any other Security which would be due and payable
   upon a declaration of acceleration of the Maturity thereof pursuant to
   Section 502, or adversely affect any right of repayment at the option of the
   Holder of any Security, or reduce the amount of, or postpone the date fixed
   for, the payment of any sinking fund payment or analogous obligation, or
   change any Place of Payment where, or the coin or currency in which, any
   Security or any premium or interest thereon is payable, or impair the right
   to institute suit for the enforcement of any such payment on or after the
   Stated Maturity thereof (or, in the case of redemption, on or after the
   Redemption Date), or modify the provisions of this Indenture with respect to
   the subordination of the Securities in a manner adverse to the Holders, or
   adversely affect the right to convert any Security as provided in Article
   Fifteen (except as permitted by Section 901(9)), or

   such supplemental indenture, or the consent of whose Holders is required for
   any waiver (of compliance with certain provisions of this Indenture or
   certain defaults hereunder and their consequences) provided for in this
   Indenture, or

      (3)  modify any of the provisions of this Section, Section 513 or Section
   1008, except to increase any such percentage or to provide that certain
   other provisions of this Indenture cannot be modified or waived without the
   consent of the Holder of each Outstanding Security affected thereby;
   provided, however, that this clause shall not be deemed to require the
   consent of any Holder with respect to changes in the references to "the
   Trustee" and concomitant changes in this Section and Section 1008, or the
   deletion of this proviso, in accordance with the requirements of Sections
   611 and 901(8).

A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with respect to such
covenant or other provision, shall be deemed not to affect the rights under
this Indenture of the Holders of Securities of any other series.

      It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it
shall be sufficient if such Act shall approve the substance thereof.


SECTION 903.  Execution of Supplemental Indentures.

      In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby
of the trusts created by





                                      -56-
<PAGE>   67
this Indenture, the Trustee shall be entitled to receive, and (subject to
Section 601) shall be fully protected in relying upon, an Opinion of Counsel
stating that the execution of such supplemental indenture is authorized or
permitted by this Indenture. The Trustee may, but shall not be obligated to,
enter into any such supplemental indenture which affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise.


SECTION 904.  Effect of Supplemental Indentures.

      Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every
Holder of Securities theretofore or thereafter authenticated and delivered
hereunder shall be bound thereby.


SECTION 905.  Conformity with Trust Indenture Act.

      Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act.


SECTION 906.  Reference in Securities to Supplemental Indentures.

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


SECTION 907.  Subordination Unimpaired.

      Notwithstanding any provision in this Indenture or otherwise, the rights
of Entitled Persons in respect of Other Financial Obligations under this

Securities may, at any time and from time to time, be modified in any respect
or eliminated without the consent of any Entitled Person in respect of Other
Financial Obligations.

                                   COVENANTS


SECTION 1001.  Payment of Principal, Premium and Interest.

      The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any
premium and interest on the Securities of that series in accordance with the
terms of the Securities and this Indenture.


SECTION 1002.  Maintenance of Office or Agency.

      The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange, where convertible Securities may be
surrendered for conversion and where notices and demands to or upon the Company
in respect of the Securities of that series and this Indenture may be served.
The Company will give prompt written notice to the Trustee of the location, and
any change in the location, of such office or agency. If at any time the
Company shall fail to maintain any such required office or agency or shall fail
to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, surrenders, notices and demands.

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


SECTION 1003.  Money for Securities Payments to Be Held in Trust.

      If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities, it will, on or before each due date of the
principal of or any premium or interest on any of the Securities of that
series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal and any premium and 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.





                                      -58-
<PAGE>   69
      Whenever the Company shall have one or more Paying Agents for any series
of Securities, it will, prior to each due date of the principal of or any
premium or interest on any Securities of that series, deposit with a Paying
Agent a sum sufficient to pay such amount, such sum to be held as provided by
the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its action or failure so to act.

      The Company will cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will (1) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the
Securities of that series, upon the written request of the Trustee, forthwith
pay to the Trustee all sums held in trust by such Paying Agent for payment in
respect of the Securities of that series.

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

      Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of or any premium or
interest on any Security of any series 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 shall
thereafter, as an unsecured general creditor, look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in a newspaper published in
the English language, customarily published on each Business Day and of general
circulation in the Borough of Manhattan, The City of New York, notice that such
money remains unclaimed and that, after a date specified therein, which shall
not be less than 30 days from the date of such publication, any unclaimed
balance of such money then remaining will be repaid to the Company.

<PAGE>   70
SECTION 1004.  Statement by Officers as to Default.

      The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year of the Company ending after the date hereof, an Officers'
Certificate, stating whether or not to the best knowledge of the signers
thereof the Company is in default in the performance and observance of any of
the terms, provisions and conditions of this Indenture (without regard to any
period of grace or requirement of notice provided hereunder) and, if the
Company shall be in default, specifying all such defaults and the nature and
status thereof of which they may have knowledge. The Company shall deliver to
the Trustee written notice of the occurrence of any Default within ten Business
Days of the Company becoming aware thereof.


SECTION 1005.  Existence.

      Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence and the rights (charter and statutory) and franchises of the Company;
provided, however, that the Company shall not be required to preserve any such
right or franchise if the Board of Directors shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company and that the loss thereof is not disadvantageous in any material
respect to the Holders.


SECTION 1006.  Maintenance of Properties.

      The Company will cause all properties used or useful in the conduct of
its business or the business of any Subsidiary to be maintained and kept in
good condition, repair and working order and supplied with all necessary
equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided,
however, that nothing in this Section shall prevent the Company from
discontinuing the operation or maintenance of any of such properties if such
discontinuance is, in the judgment of the Company, desirable in the conduct of
its business or the business of any Subsidiary and not disadvantageous in any
material respect to the Holders.


SECTION 1007.  Payment of Taxes and Other Claims.

      The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income, profits or property of the Company or any Subsidiary, and (2)
all lawful claims for labor, materials and supplies which, if unpaid, might by
law become a lien upon the property of the Company





                                      -60-
<PAGE>   71
or any Subsidiary; provided, however, that the Company shall not be required to
pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim whose amount, applicability or validity is being contested in
good faith by appropriate proceedings and for which adequate provision is made.


SECTION 1008.  Waiver of Certain Covenants.

      Except as otherwise specified as contemplated by Section 301 for
Securities of such series, the Company may, with respect to the Securities of
any series, omit in any particular instance to comply with any term, provision
or condition set forth in any covenant provided pursuant to Section 301(18),
901(2) or 901(7) for the benefit of the Holders of such series or in any of
Sections 1005 to 1007, inclusive, if before the time for such compliance the
Holders of not less than a majority in principal amount of the Outstanding
Securities of such series shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such term,
provision or condition, but no such waiver shall extend to or affect such term,
provision or condition except to the extent so expressly waived, and, until
such waiver shall become effective, the obligations of the Company and the
duties of the Trustee in respect of any such term, provision or condition shall
remain in full force and effect.


                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES


SECTION 1101.  Applicability of Article.

      Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for such Securities) in
accordance with this Article.


SECTION 1102.  Election to Redeem; Notice to Trustee.

      The election of the Company to redeem any Securities shall be evidenced
by a Board Resolution or in another manner specified as contemplated by Section
301 for such Securities. In case of any redemption at the election of the
Company of less than all the Securities of any series (including any such
redemption affecting only a single Security), the Company shall, at least 60
days prior to the Redemption Date fixed by the Company (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such Redemption
Date, of the principal amount of Securities of such series to be redeemed and,
if applicable, of the tenor of the Securities to be redeemed. In the case of
any redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company





                                      -61-
<PAGE>   72
shall furnish the Trustee with an Officers' Certificate evidencing compliance
with such restriction.


SECTION 1103.  Selection by Trustee of Securities to Be Redeemed.

      If less than all the Securities of any series are to be redeemed (unless
all the Securities of such series and of a specified tenor are to be redeemed
or unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of
a portion of the principal amount of any Security of such series, provided that
the unredeemed portion of the principal amount of any Security shall be in an
authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security. If less than all the Securities of such series
and of a specified tenor are to be redeemed (unless such redemption affects
only a single Security), the particular Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by the Trustee,
from the Outstanding Securities of such series and specified tenor not
previously called for redemption in accordance with the preceding sentence.  If
any convertible Security selected for partial redemption is converted in part
before termination of the conversion right with respect to the portion of the
Security so selected, the converted portion of such Security shall be deemed
(so far as may be) to be the portion selected for redemption.  Convertible
Securities which have been converted during a selection of Securities to be
redeemed shall be treated by the Trustee as Outstanding for the purposes of
such selection.

      The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption as aforesaid and, in case of any Securities
selected for partial redemption as aforesaid, the principal amount thereof to
be redeemed.

      The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting a series of Securities comprised of only a
single Security, whether such Security is to be redeemed in whole or in part.
In the case of any such redemption in part, the unredeemed portion of the
principal amount of the Security shall be in an authorized denomination (which
shall not be less than the minimum authorized denomination) for such Security.

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





                                      -62-
<PAGE>   73
SECTION 1104.  Notice of Redemption.

      Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 nor more than 60 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at his address appearing in the
Security Register.

      All notices of redemption shall state:

      (1)  the Redemption Date,

      (2)  the Redemption Price,

      (3)  if less than all the Outstanding Securities of any series consisting
   of more than a single Security are to be redeemed, the identification (and,
   in the case of partial redemption of any such Securities, the principal
   amounts) of the particular Securities to be redeemed and, if less than all
   the entire principal amount of any series consisting of a single Security
   are to be redeemed, the portion of the principal amount of the particular
   Security to be redeemed,

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

      (5)  if the Securities to be redeemed are Convertible Securities, the
   Conversion Price, the date on which the right to convert the Securities to
   be redeemed will terminate and the place or places where such Securities may
   be surrendered for conversion,

      (6)  the CUSIP numbers, if any, of the Securities to be redeemed,

      (7)  the place or places where each such Security is to be surrendered
   for payment of the Redemption Price, and

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

      Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company and shall be irrevocable.


SECTION 1105.  Deposit of Redemption Price.

      Prior to any Redemption Date, the Company shall deposit with the Trustee
or with a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 1003) an amount of money
sufficient to pay the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment





                                      -63-
<PAGE>   74
Date) accrued interest on, all the Securities which are to be redeemed on that
date other than any convertible Securities called for redemption on that date
which have been converted prior to the date of such deposit.

      If any convertible Security called for redemption is converted, any money
deposited with the Trustee or with any Paying Agent or so segregated and held
in trust for the redemption of such Security shall (subject to any right of the
Holder of such Security or any Predecessor Security to receive interest as
provided in the last paragraph of Section 307) be paid to the Company upon
Company Request or, if then held by the Company, shall be discharged from such
trust.


SECTION 1106.  Securities Payable on Redemption Date.

      Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. In addition, such
Securities shall, if convertible by their terms into Common Stock, cease from
and after the date fixed for redemption (unless an earlier date shall be
specified in a Board Resolution, Officers' Certificate or executed supplemental
indenture or pursuant to which the terms of the Securities of such series were
established) to be convertible into Common Stock (unless the Company shall
default in the payment of the Redemption Price). Upon surrender of any such
Security for redemption in accordance with said notice, such Security shall be
paid by the Company at the Redemption Price, together with accrued interest to
the Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 301, instalments of interest whose Stated Maturity is
on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

      If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal and any premium shall, until paid, bear
interest from the Redemption Date at the rate prescribed therefor in the
Security. In addition, such Security shall, if convertible by its terms into
Common Stock, remain convertible into Common Stock until the principal (and
premium, if any) of such Security shall have been paid or duly provided for.


SECTION 1107.  Securities Redeemed in Part.

      Any Security which is to be redeemed only in part shall be surrendered at
a Place of Payment therefor (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Company and the Trustee duly executed by, the Holder thereof or his
attorney duly authorized in writing),





                                      -64-
<PAGE>   75
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 of like tenor, of any authorized denomination
as requested by such Holder, in aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of the Security so
surrendered.


                                 ARTICLE TWELVE

                                 SINKING FUNDS


SECTION 1201.  Applicability of Article.

      The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of any series except as otherwise specified as
contemplated by Section 301 for such Securities.

      The minimum amount of any sinking fund payment provided for by the terms
of any Securities 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
such Securities is herein referred to as an "optional sinking fund payment". If
provided for by the terms of any Securities, the cash amount of any sinking
fund payment may be subject to reduction as provided in Section 1202. Each
sinking fund payment shall be applied to the redemption of Securities as
provided for by the terms of such Securities.


SECTION 1202.  Satisfaction of Sinking Fund Payments with Securities.

      The Company (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been converted pursuant to Article Fifteen or
which have been redeemed either at the election of the Company pursuant to the
terms of such Securities or through the application of permitted optional
sinking fund payments pursuant to the terms of such Securities or which have
otherwise been acquired by the Company, in each case in satisfaction of all or
any part of any sinking fund payment with respect to any Securities of such
series required to be made pursuant to the terms of such Securities as and to
the extent provided for by the terms of such Securities; provided that the
Securities to be so credited have not been previously so credited. The
Securities to be so credited shall be received and credited for such purpose by
the Trustee at the Redemption Price, as specified in the Securities so to be
redeemed, for redemption through operation of the sinking fund and the amount
of such sinking fund payment shall be reduced accordingly.

SECTION 1203.  Redemption of Securities for Sinking Fund.

      Not less than 60 days prior to each sinking fund payment date for any
Securities, the Company  will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing sinking fund payment for such
Securities pursuant to the terms of such Securities, 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 pursuant
to Section 1202 and will also deliver to the Trustee any Securities to be so
delivered. Not less than 30 days prior to each such sinking fund payment date,
the Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 1104. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1106 and 1107.


                                ARTICLE THIRTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE


SECTION 1301.  Company's Option to Effect Defeasance or Covenant Defeasance.

      The Company may elect, at its option at any time, to have Section 1302 or
Section 1303 applied to any Securities or any series of Securities, as the case
may be, designated pursuant to Section 301 as being defeasible pursuant to such
Section 1302 or 1303, in accordance with any applicable requirements provided
pursuant to Section 301 and upon compliance with the conditions set forth below
in this Article. Any such election shall be evidenced by a Board Resolution or
in another manner specified as contemplated by Section 301 for such Securities.


SECTION 1302.  Defeasance and Discharge.

      Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, the
Company shall be deemed to have been discharged from its obligations, and the
provisions of Article Fourteen shall cease to be effective, with respect to
such Securities as provided in this Section on and after the date the
conditions set forth in Section 1304 are satisfied (hereinafter called
"Defeasance"). For this purpose, such Defeasance means that the Company shall
be deemed to have paid and discharged the entire indebtedness represented by
such Securities and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), subject to the following which shall survive until
otherwise terminated or discharged hereunder: (1) the rights of Holders of such
Securities to receive, solely from





                                      -66-
<PAGE>   77
the trust fund described in Section 1304 and as more fully set forth in such
Section, payments in respect of the principal of and any premium and interest

respect to such Securities under Sections 304, 305, 306, 1002 and 1003, (3) the

its option (if any) to have this Section applied to any Securities
notwithstanding the prior exercise of its option (if any) to have Section 1303
applied to such Securities.


SECTION 1303.  Covenant Defeasance.

      Upon the Company's exercise of its option (if any) to have this Section
applied to any Securities or any series of Securities, as the case may be, (1)
the Company shall be released from its obligations under Sections 1006 through
1007, inclusive, and any covenants provided pursuant to Section 301(18), 901(2)
or 901(7) for the benefit of the Holders of such Securities, and (2) the
occurrence of any event specified in Section 501(3) shall be deemed not to be
an Event of Default, and (3) the occurrence of any event specified in Section
503(2)(C) (with respect to any of Sections 1006 through 1007 inclusive, and any
such covenants provided pursuant to Section 301(18), 901(2) and 901(7) shall be
deemed not to be or result in a Default and (4) the provisions of Article
Fourteen shall cease to be effective, in each case with respect to such
Securities as provided in this Section on and after the date the conditions set
forth in Section 1304 are satisfied (hereinafter called "Covenant Defeasance").
For this purpose, such Covenant Defeasance means that, with respect to such
Securities, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such specified
Section or Article Fourteen, whether directly or indirectly by reason of any
reference elsewhere herein to any such Section or Article or by reason of any
reference in any such Section or Article to any other provision herein or in
any other document, but the remainder of this Indenture and such Securities
shall be unaffected thereby.


SECTION 1304.  Conditions to Defeasance or Covenant Defeasance.

      The following shall be the conditions to the application of Section 1302
or Section 1303 to any Securities or any series of Securities, as the case may
be:

   deposited with the Trustee (or another trustee which satisfies the

   hereunder) as trust funds in trust for the purpose of making the following

   benefits of the Holders of such Securities, (A) in the case of Securities
   denominated in a foreign currency, money in such foreign currency or Foreign

   interest in respect thereof in accordance with their terms will provide, not
   later than one day before the due date of any payment, such foreign currency
   in an amount or (B) in the case of Securities denominated in U.S. dollars,
   U.S. dollars or U.S. Government Obligations which through the scheduled

   their terms will provide, not later than one day before the due date of any
   payment, U.S. dollars in an amount, or (C) a combination of money and U.S.
   Government Obligations or Foreign Government Obligations (as applicable), in
   each case sufficient, in the opinion of a nationally recognized firm of
   independent public accountants expressed in a written certification thereof
   delivered to the Trustee, to pay and discharge, and which shall be applied
   by the Trustee (or any such other qualifying trustee) to pay and discharge,
   the principal of and any premium and interest on such Securities on the
   respective Stated Maturities, in accordance with the terms of this Indenture
   and such Securities. As used herein, "U.S. Government Obligation" means (x)
   any security which is (i) a direct obligation of the United States of
   America for the payment of which the full faith and credit of the United
   States of America is pledged or (ii) an obligation of a Person controlled or
   supervised by and acting as an agency or instrumentality of the United
   States of America the payment of which is unconditionally guaranteed as a
   full faith and credit obligation by the United States of America, which, in
   either case (i) or (ii), is not callable or redeemable at the option of the
   issuer thereof, and (y) any depositary receipt issued by a bank (as defined
   in Section 3(a)(2) of the Securities Act) as custodian with respect to any
   U.S. Government Obligation which is specified in Clause (x) above and held
   by such bank for the account of the holder of such depositary receipt, or
   with respect to any specific payment of principal of or interest on any U.S.
   Government Obligation which is so specified and held, provided that (except
   as required by law) such custodian is not authorized to make any deduction
   from the amount payable to the holder of such depositary receipt from any
   amount received by the custodian in respect of the U.S. Government
   Obligation or the specific payment of principal or interest evidenced by
   such depositary receipt.  As used herein, "Foreign Government Obligation"
   means any security denominated in a Foreign Currency which is (i) a direct
   obligation of a foreign government or governments for the payment of which
   the full faith and credit of such foreign government or governments is
   pledged or (ii) an obligation of a Person controlled or supervised by and
   acting as an agency or instrumentality of such foreign government or
   governments the payment of which is unconditionally guaranteed as a full
   faith and credit obligation by such foreign government, which, in either
   case (i) or (ii) is not callable or redeemable at the option of the issuer
   thereof.

      (2)  In the event of an election to have Section 1302 apply to any
   Securities or any series of Securities, as the case may be, the Company
   shall have delivered to the Trustee an Opinion of Counsel stating that
   (A)(x) the Company has received from, or there has been published by, the
   Internal Revenue Service a ruling or (y) since the date of this instrument,
   there has been a change in the applicable Federal income tax law, in either
   case (x) or (y) to the effect that, and based thereon such opinion shall
   confirm that, the Holders of such Securities will not recognize gain or loss
   for Federal income tax purposes as a result of the deposit, Defeasance and
   discharge to be effected with





                                      -68-
<PAGE>   79
   respect to such Securities and will be subject to Federal income tax on the
   same amount, in the same manner and at the same times as would be the case
   if such deposit, Defeasance and discharge were not to occur and (B) if
   Securities of such series Securities are then listed on the New York Stock
   Exchange, to the effect that the Securities of such series will not be
   delisted as a result of such election.

      (3)  In the event of an election to have Section 1303 apply to any
   Securities or any series of Securities, as the case may be, the Company
   shall have delivered to the Trustee an Opinion of Counsel to the effect that
   the Holders of such Securities will not recognize gain or loss for Federal
   income tax purposes as a result of the deposit and Covenant Defeasance to be
   effected with respect to such Securities and will be subject to Federal
   income tax on the same amount, in the same manner and at the same times as
   would be the case if such deposit and Covenant Defeasance were not to occur.

      (4)  The Company shall have delivered to the Trustee an Officer's
   Certificate to the effect that neither such Securities nor any other
   Securities of the same series, if then listed on any securities exchange,
   will be delisted as a result of such deposit.


      (5)  No event which is, or after notice or lapse of time or both would
   become, a Default with respect to such Securities or any other Securities
   shall have occurred and be continuing at the time of such deposit or, with
   regard to any such event specified in Sections 501(1) and (2), at any time
   on or prior to the 90th day after the date of such deposit or, if longer,
   ending on the day following the expiration of the longest preference period
   applicable to the Company under Federal or State Law in respect of such
   deposit (it being understood that this condition shall not be deemed
   satisfied until after the expiration of such period).

      (6)  Such Defeasance or Covenant Defeasance shall not cause the Trustee
   to have a conflicting interest within the meaning of the Trust Indenture Act
   (assuming all Securities are in default within the meaning of such Act).

      (7)  At the time of such deposit, (A) no default in the payment of all or
   a portion of principal of (or premium, if any) or interest on any Senior
   Indebtedness shall have occurred and be continuing, and no event of default
   with respect to any Senior Indebtedness shall have occurred and be
   continuing and shall have resulted in such Senior Indebtedness becoming or
   being declared due and payable prior to the date on which it would otherwise
   have become due and payable and (B) such Defeasance or Covenant Defeasance
   shall not result in a breach or violation of, or constitute a default under,
   any other agreement or instrument to which the Company is a party or by
   which it is bound.

      (8)  Such Defeasance or Covenant Defeasance shall not result in the trust
   arising from such deposit constituting an investment company within the
   meaning of the Investment Company Act unless such trust shall be registered
   under such Act or exempt from registration thereunder.





                                      -69-
<PAGE>   80
      (9)   The Company shall have delivered to the Trustee an Officer's
   Certificate and an Opinion of Counsel, each stating that all conditions
   precedent with respect to such Defeasance or Covenant Defeasance have been
   complied with including any conditions imposed in connection therewith
   pursuant to Section 301.


SECTION 1305.  Deposited Money and U.S. Government Obligations to Be
   Held in Trust; Miscellaneous Provisions.

        Subject to the provisions of the last paragraph of Section 1003, all
money, U.S. Government Obligations and Foreign Government Obligations
(including the proceeds thereof) deposited with the Trustee or other qualifying
trustee (solely for purposes of this Section and Section 1306, the Trustee and
any such other trustee are referred to collectively as the "Trustee") pursuant
to Section 1304 in respect of any Securities shall be held in trust and applied
by the Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any such Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities, of all sums due and to become due
thereon in respect of principal and any premium and interest, but money so held
in trust need not be segregated from other funds except to the extent required
by law. Money, U.S. Government Obligations and Foreign Government Obligations
so held in trust shall not be subject to the provisions of Article Fourteen.

        The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations or
Foreign Government Obligations deposited pursuant to Section 1304 or the
principal and interest received in respect thereof other than any such tax, fee
or other charge which by law is for the account of the Holders of Outstanding
Securities.

        Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or U.S. Government Obligations or Foreign Government Obligations held by
it as provided in Section 1304 with respect to any Securities which, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect the Defeasance or Covenant Defeasance, as the case may be, with respect
to such Securities.


SECTION 1306.  Reinstatement.

      If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 1302 or 1303 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to





                                      -70-
<PAGE>   81
apply all money held in trust pursuant to Section 1305 with respect to such
Securities in accordance with this Article; provided, however, that if the
Company makes any payment of principal of or any premium or interest on any
such Security following such reinstatement of its obligations, the Company
shall be subrogated to the rights (if any) of the Holders of such Securities to
receive such payment from the money so held in trust.

                                ARTICLE FOURTEEN

                          SUBORDINATION OF SECURITIES


SECTION 1401.  Securities Subordinate to Senior Indebtedness.

      The Company covenants and agrees, and each Holder of a Security, by his
acceptance thereof, likewise covenants and agrees, that, to the extent and in
the manner hereinafter set forth in this Article and except to the extent
otherwise provided pursuant to Section 301(22), the indebtedness represented by
the Securities and the payment of the principal of (and premium, if any) and
interest on each and all of the Securities are hereby expressly made
subordinate and subject in right of payment to the prior payment in full of all
Senior Indebtedness and, to the extent set forth in this Article, all Other
Financial Obligations.


SECTION 1402.  Payment Over of Proceeds Upon Dissolution, Etc.

      In the event of (a) any insolvency or bankruptcy case or proceeding, or
any receivership, liquidation, reorganization or other similar case or
proceeding in connection therewith, relative to the Company or to its
creditors, as such, or to its assets, or (b) any liquidation, dissolution or
other winding up of the Company, whether voluntary or involuntary and whether
or not involving insolvency or bankruptcy, or (c) any assignment for the
benefit of creditors or any other marshalling of assets and liabilities of the
Company, then and in any such event the holders of Senior Indebtedness shall be
entitled to receive payment in full of all amounts due or to become due on or
in respect of all Senior Indebtedness, or provision shall be made for such
payment in money or money's worth, before the Holders of the Securities are
entitled to receive any payment on account of principal of (or premium, if any)
or interest on the Securities, and to that end the holders of Senior
Indebtedness shall be entitled to receive, for application to the payment
thereof, any payment or distribution of any kind or character, whether in cash,
property or securities, including any such payment or distribution which may be
payable or deliverable by reason of the payment of any other indebtedness of
the Company being subordinated to the payment of the Securities, which may be
payable or deliverable in respect of the Securities in any such case,
proceeding, dissolution, liquidation or other winding up or event.





                                      -71-
<PAGE>   82
      In the event that, notwithstanding the foregoing provisions of this
Section, the Trustee or the Holder of any Security shall have received any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, including any such payment or
distribution which may be payable or deliverable by reason of the payment of
any other indebtedness of the Company being subordinated to the payment of the
Securities, before all Senior Indebtedness is paid in full or payment thereof
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 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 application to the payment of all
Senior Indebtedness remaining unpaid, to the extent necessary to pay all Senior
Indebtedness in full, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness.

      For purposes of this Article only, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other
corporation provided for by a plan of reorganization or readjustment which are
subordinated in right of payment to all Senior Indebtedness which may at the
time be outstanding to substantially the same extent as, or to a greater extent
than, the Securities are so subordinated as provided in this Article.  The
consolidation of the Company with, or the merger of the Company into, another
Person or the liquidation or dissolution of the Company following the
conveyance or transfer of its properties and assets substantially as an
entirety to another Person upon the terms and conditions set forth in Article
Eight shall not be deemed a dissolution, winding up, liquidation,
reorganization, assignment for the benefit of creditors or marshalling of
assets and liabilities of the Company for the purposes of this Section if the
Person formed by such consolidation or into which the Company is merged or the
Person which acquires by conveyance or transfer such properties and assets
substantially as an entirety, as the case may be, shall, as a part of such
consolidation, merger, conveyance or transfer, comply with the conditions set
forth in Article Eight.


SECTION 1403.  Prior Payment to Senior Indebtedness Upon Acceleration of
    Securities.

      In the event that any Securities are declared due and payable before
their Stated Maturity, then and in such event the holders of Senior
Indebtedness shall be entitled to receive payment in full of all amounts due or
to become due on or in respect of all Senior Indebtedness or provision shall be
made for such payment in money or money's worth, before the Holders of the
Securities are entitled to receive any payment (including any payment which may
be payable by reason of the payment of any other indebtedness of the Company
being subordinated to the payment of the Securities) by the Company on account
of the principal of (or premium, if any) or interest on the Securities or on
account of the purchase or other acquisition of Securities; provided, however,
that nothing in this Section shall prevent the satisfaction of any sinking fund
payment in accordance





                                      -72-
<PAGE>   83
with Article Twelve by delivering and crediting pursuant to Section 1202
Securities which have been acquired (upon redemption or otherwise) prior to
such declaration of acceleration.

      In the event that, notwithstanding the foregoing, the Company shall make
any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and if such fact shall, at or prior to
the time of such payment, have been made known to the Trustee or, as the case
may be, such Holder, then and in such event such payment shall be paid over and
delivered forthwith to the Company.

      The provisions of this Section shall not apply to any payment with
respect to which Section 1402 would be applicable.


SECTION 1404.  No Payment When Senior Indebtedness in Default.

      (a) In the event and during the continuation of any default in the
payment of principal of (or premium, if any) or interest on any Senior
Indebtedness beyond any applicable grace period with respect thereto, or in the
event that any event of default with respect to any Senior Indebtedness shall
have occurred and be continuing permitting the holders of such Senior
Indebtedness (or a trustee on behalf of the holders thereof) to declare such
Senior Indebtedness due and payable prior to the date on which it would
otherwise have become due and payable, unless and until such event of default
shall have been cured or waived or shall have ceased to exist and such
acceleration shall have been rescinded or annulled, or (b) in the event any
judicial proceeding shall be pending with respect to any such default in
payment or event of default, then no payment (including any payment which may
be payable by reason of the payment of any other indebtedness of the Company
being subordinated to the payment of the Securities) shall be made by the
Company on account of principal of (or premium, if any) or interest on the
Securities or on account of the purchase or other acquisition of Securities;
provided, however, that nothing in this Section shall prevent the satisfaction
of any sinking fund payment in accordance with Article Twelve by delivering and
crediting pursuant to Section 1202 Securities which have been acquired (upon
redemption or otherwise) prior to such default in payment or event of default.

      In the event that, notwithstanding the foregoing, the Company shall make
any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and if such fact shall, at or prior to
the time of such payment, have been made known to the Trustee or, as the case
may be, such Holder, then and in such event such payment shall be paid over and
delivered forthwith to the Company.

      The provisions of this Section shall not apply to any payment with
respect to which Section 1402 would be applicable.





                                      -73-
<PAGE>   84
SECTION 1405.  Payment Permitted in Certain Situations.

      Nothing contained in this Article or elsewhere in this Indenture or in
any of the Securities shall prevent (a) the Company, at any time except during
the pendency of any case, proceeding, dissolution, liquidation or other winding
up, assignment for the benefit of creditors or other marshalling of assets and
liabilities of the Company referred to in Section 1402 or under the conditions
described in Section 1403 or 1404, from making payments at any time of
principal of (and premium, if any) or interest on the Securities or (b) the
application by the Trustee of any money deposited with it hereunder to the
payment of or on account of the principal of (and premium, if any) or interest
on the Securities of any series or the retention of such payment by the Holder,
if, at the time of such application by the Trustee, it did not have actual
knowledge that such payment would have been prohibited by the provisions of
this Article.


SECTION 1406.  Subrogation to Rights of Holders of Senior Indebtedness.

      Subject to the payment in full of all Senior Indebtedness, the Holders of
the Securities shall be subrogated to the extent of the payments or
distributions made to the holders of such Senior Indebtedness pursuant to the
provisions of this Article (equally and ratably with the holders of all
Existing Subordinated Indebtedness and 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 or the Existing Subordinated
Indebtedness are subordinated and is entitled to like rights of subrogation) to
the rights of the holders of such Senior Indebtedness to receive payments and
distributions of cash, property and securities applicable to the Senior
Indebtedness until the principal of (and premium, if any) and interest on the
Securities shall be paid in full.  For purposes of such subrogation, no
payments or distributions to the holders of the Senior Indebtedness of any
cash, property or securities to which the Holders of the Securities or the
Trustee would be entitled except for the provisions of this Article, and no
payments over pursuant to the provisions of this Article to the holders of
Senior Indebtedness by Holders of the Securities or the Trustee, shall, as
among the Company, its creditors other than holders of Senior Indebtedness and
the Holders of the Securities, be deemed to be a payment or distribution by the
Company to or on account of the Senior Indebtedness.


SECTION 1407.  Provisions Solely to Define Relative Rights.

      The provisions of this Article are and are intended solely for the
purpose of defining the relative rights of the Holders of the Securities on the
one hand and the holders of Senior Indebtedness (and, in the case of Section
1415, Entitled Persons in respect of Other Financial Obligations) on the other
hand.  Nothing contained in this Article or elsewhere in this Indenture or in
the Securities is intended to or shall (a) impair, as among the Company, its
creditors other than holders of Senior Indebtedness and other than Entitled
Persons in respect of Other Financial Obligations and the Holders of the
Securities, the obligation of the Company, which is absolute and unconditional
(and

which, subject to the rights under this Article of the holders of Senior
Indebtedness and Entitled Persons in respect of Other Financial 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 (and premium, if any) and
interest on the Securities as and when the same shall become due and payable in
accordance with their terms; or (b) affect the relative rights against the
Company of the Holders of the Securities and creditors of the Company other
than the holders of Senior Indebtedness and Entitled Persons in respect of
Other Financial Obligations; or (c) prevent the Trustee or the Holder of any
Security from exercising all remedies otherwise permitted by applicable law
upon default under this Indenture, subject to the rights, if any, under this
Article of the holders of Senior Indebtedness and under Section 1415 of
Entitled Persons in respect of Other Financial Obligations, to receive cash,
property and securities otherwise payable or deliverable to the Trustee or such
Holder.


SECTION 1408.  Trustee to Effectuate Subordination.

      Each Holder of a Security by his acceptance thereof authorizes and
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article and
appoints the Trustee his attorney-in-fact for any and all such purposes.


SECTION 1409.  No Waiver of Subordination Provisions.

      No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such holder, or by any
non-compliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof any such holder may have or be
otherwise charged with.

      Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness (and Entitled Persons in respect of Other
Financial Obligations) may, at any time and from time to time, without the
consent of or notice to the Trustee or the Holders of the Securities, without
incurring responsibility to the Holders of the Securities and without impairing
or releasing the subordination provided in this Article or the obligations
hereunder of the Holders of the Securities to the holders of Senior
Indebtedness and Entitled Persons, in respect of Other Financial Obligations,
do any one or more of the following: (i) change the manner, place or terms of
payment or extend the time of payment of, or renew or alter, Senior
Indebtedness or Other Financial Obligations, or otherwise amend or supplement
in any manner Senior Indebtedness or Other Financial Obligations or any
instrument evidencing the same or any agreement under which Senior Indebtedness
is or Other Financial Obligations are outstanding; (ii) sell, exchange, release
or otherwise deal with any property pledged, mortgaged or otherwise securing
Senior Indebtedness or Other Financial Obligations; (iii) release any





                                      -75-
<PAGE>   86
Person liable in any manner for the collection of Senior Indebtedness or Other
Financial Obligations; and (iv) exercise or refrain from exercising any rights
against the Company and any other Person.


SECTION 1410.  Notice to Trustee.

      The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by
the Trustee in respect of the Securities.  Notwithstanding the provisions of
this Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until the Trustee shall have received written notice thereof from the
Company or a holder of Senior Indebtedness or from any trustee therefor or from
any Entitled Persons in respect of Other Financial Obligations; and, prior to
the receipt of any such written notice, the Trustee, subject to the provisions
of Section 601, shall be entitled in all respects to assume that no such facts
exist.

      Subject to the provisions of Section 601, the Trustee shall be entitled
to rely on the delivery to it of a written notice by a Person representing
himself to be a holder of Senior Indebtedness (or a trustee therefor) or an
Entitled Person in respect of Other Financial Obligations to establish that
such notice has been given by a holder of Senior Indebtedness (or a trustee
therefor) or an Entitled Person in respect of Other Financial Obligations.  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 an Entitled Person in respect of Other Financial Obligations to
participate in any payment or distribution pursuant to this Article, the
Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of Senior Indebtedness or Other
Financial Obligations held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article, and if such evidence
is not furnished, the Trustee may defer any payment to such Person pending
judicial determination as to the right of such Person to receive such payment.


SECTION 1411.  Reliance on Judicial Order or Certificate of Liquidating Agent.

      Upon any payment or distribution of assets of the Company referred to in
this Article, the Trustee, subject to the provisions of Section 601, and the
Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit
of creditors, agent or other Person making such payment or distribution,
delivered to the Trustee or to the Holders of Securities, for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, the holders of Senior





                                      -76-
<PAGE>   87
Indebtedness and other indebtedness of the Company and the Entitled Persons in
respect of Other Financial 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.


SECTION 1412.  Trustee Not Fiduciary for Holders of Senior Indebtedness or
   Entitled Persons.

      The Trustee shall not be deemed to owe any fiduciary duty to the holders
of Senior Indebtedness or Entitled Persons in respect of Other Financial
Obligations and shall not be liable to any such holders or creditors if it
shall in good faith mistakenly pay over or distribute to Holders of Securities
or to the Company or to any other Person cash, property or securities to which
any holders of Senior Indebtedness or Entitled Persons in respect of Other
Financial Obligations shall be entitled by virtue of this Article or otherwise.


SECTION 1413.  Rights of Trustee as Holder of Senior Indebtedness or Entitled
   Person; Preservation of Trustee's Rights.

      The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article with respect to any Senior Indebtedness which
may at any time be held by it and with respect to any Other Financial
Obligations owed to the Trustee as an Entitled Person, to the same extent as
any other holder of Senior Indebtedness or Entitled Person in respect of Other
Financial Obligations, as the case may be, and nothing in this Indenture shall
deprive the Trustee of any of its rights as such holder or Entitled Person.

      Nothing in this Article shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 607.


SECTION 1414.  Article Applicable to Paying Agents.

      In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article shall in such case (unless the context otherwise
requires) be construed as extending to and including such Paying Agent within
its meaning as fully for all intents and purposes as if such Paying Agent were
named in this Article in addition to or in place of the Trustee; provided,
however, that Section 1413 shall not apply to the Company or any Affiliate of
the Company if it or such Affiliate acts as Paying Agent.


SECTION 1415.  Securities to Rank Pari Passu with Existing Subordinated
   Indebtedness.

      (a) Subject to the provisions of this Section and to any provisions
established or determined with respect to Securities of any series pursuant to
Section 301, the Securities





                                      -77-
<PAGE>   88
shall rank pari passu in right of payment with all other Securities and the
Existing Subordinated Indebtedness.

      (b) Upon the occurrence of any of the events specified in clauses (a),
(b) and (c) of the first paragraph of Section 1402, the provisions of that
Section and the corresponding provisions of each indenture or other instrument
or document establishing or governing the terms of any Existing Subordinated
Indebtedness shall be given effect on a pro rata basis to determine the amount
of cash, property or securities which may be payable or deliverable as between
the holders of Senior Indebtedness, on the one hand, and the Holders of
Securities and holders of Existing Subordinated Indebtedness, on the other
hand.

      (c) If, after giving effect to the provisions of Section 1402, Section
1406 and the respective corresponding provisions of each indenture or other
instrument or document establishing or governing the terms of any Senior
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 Entitled Persons in respect of Other Financial
Obligations shall not have received payment in full of all amounts due or to
become due on or in respect of such Other Financial 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 Entitled Persons in
respect of Other Financial Obligations) to pay or provide for the payment of
the Other Financial Obligations remaining unpaid, to the extent necessary to
pay all Other Financial Obligations in full, after giving effect to any
concurrent payment or distribution to or for Entitled Persons in respect of
Other Financial Obligations.  Any Excess Proceeds remaining after the payment
(or provision for payment) in full of all Other Financial Obligations shall be
available for payment or distribution in respect of the Securities.

      (d) In the event that, notwithstanding the foregoing provisions of
subsection (c) of this Section, after the occurrence of any of the events
specified in clauses (a), (b) and (c) of the first paragraph of Section 1402,
the Trustee or Holder of any Security shall have received any payment or
distribution of assets of the Company of any kind or character, whether in
cash, property or securities, before Senior Indebtedness and all Other
Financial Obligations are paid in full or payment thereof duly provided for,
and if such fact shall, at or prior to the time of such payment or
distribution, have been made known to the Trustee or, as the case may be, such
Holder, then and in such event, subject to any obligation that the Trustee or
such Holder may have pursuant to Section 1402, 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 (c).





                                      -78-
<PAGE>   89
      (e) Subject to the payment in full of all Other Financial Obligations,
the Holders 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 Entitled
Persons in respect of Other Financial Obligations and is entitled to like
rights of subrogation) to the extent of the payments or distributions made to
Entitled Persons in respect of Other Financial Obligations pursuant to
subsection (c) or (d) of this Section to the rights of the Entitled Persons in
respect of Other Financial Obligations to receive payments and distributions of
cash, property and securities applicable to the Other Financial Obligations
until the principal of (and premium, if any) and interest on the Securities
shall be paid in full.  For purposes of such subrogation, no payments or
distributions to Entitled Persons in respect of Other Financial 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 Entitled Persons in
respect of Other Financial Obligations by Holders of Securities or the Trustee,
shall, as among the Company, its creditors other than Entitled Persons in
respect of Other Financial Obligations and the Holders of Securities be deemed
to be a payment or distribution by the Company to or on account of the Other
Financial Obligations.

      (f) The provisions of subsections (c), (d) and (e) 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 Entitled Persons in respect
of Other Financial 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 (c), (d) and (e) of this Section is intended
to or shall affect the relative rights against the Company of the Holders of
the Securities and creditors of the Company other than Entitled Persons in
respect of Other Financial Obligations.

SECTION  1416.  Certain Conversions Deemed Payment.

   For purposes of this Article only, (1) the issuance and delivery of junior
securities upon conversion of Securities in accordance with Article Fifteen
shall not be deemed to constitute a payment or distribution on account of the
purchase or other acquisition of Securities, and (2) the payment, issuance or
delivery of cash, property or securities (other than junior securities) upon
conversion of a security shall be deemed to constitute payment on account of
the principal of such Securities.  For purposes of this Section, the term
"junior securities" means (a) shares of any stock of any class of the Company
and (b) securities of the Company which are subordinated in right of payment to
all Senior Indebtedness which may be outstanding at the time of issuance or
delivery of such securities to substantially the same extent as, or to a
greater extent than, the Securities are so subordinated as provided in this
Article.  Nothing contained in this Article or elsewhere in this Indenture or
in the Securities is intended to or shall impair, as among the Company, its
creditors other than holders of Senior Indebtedness and the Holders of the
Securities, the right, which is absolute and unconditional, of the Holder of
any convertible Security to convert such Security in accordance with Article
Fifteen.

                                ARTICLE FIFTEEN

                            CONVERSION OF SECURITIES

SECTION 1501. Applicability of Article.

      The Company may elect, at its option at any time, to have Section 1502
applied to any Securities or any series of Securities, as the case may be,
designated pursuant to Section 301 as being convertible into Common Stock of
the Company pursuant to such Section 1502, in accordance with any applicable
requirements provided pursuant to Section 301 and upon compliance with the
conditions set forth below in this Article.  Any such election shall be
evidenced by a Board Resolution or in another manner specified as contemplated
by Section 301 for such Securities.

SECTION 1502. Conversion Privilege and Conversion Price.

      Subject to and upon compliance with the provisions of this Article, at
the option of the Holder thereof, any Security or any portion of the principal
amount thereof which is an integral multiple of the authorized denomination
thereof may be converted at the principal amount thereof, or of such portion
thereof, into fully paid and nonassessable shares (calculated as to each
conversion to the nearest 1/100 of a share) of Common Stock of the Company, at
the conversion price for Securities of such series, determined as hereinafter
provided, in effect at the time of conversion.  Such conversion right shall
commence at the opening of business on the Initial Conversion Date and expire
at the close of business on the Final Conversion Date.  In case a Security or
portion thereof is called for redemption, such conversion right in respect of
the Security or portion so called shall expire at the close of business on the
Redemption Date, unless the Company defaults in making the payment due upon
redemption.

      The price at which shares of Common Stock shall be delivered upon
conversion of Securities of a series (herein called the "conversion price" for
Securities of such series) shall be initially the Initial Conversion Price for
Securities of such series per share of Common Stock.  The conversion price
shall be adjusted in certain instances as provided in paragraphs (1), (2), (3),
(4) and (7) of Section 1504.

SECTION 1503. Exercise of Conversion Privilege.

      In order to exercise the conversion privilege, the Holder of any Security
to be converted shall surrender such Security, duly endorsed or assigned to the
Company or in blank, at any office or agency of the Company maintained for that
purpose pursuant to Section 1002, accompanied by written notice to the Company
at such office or agency that the Holder elects to convert such Security or, if
less than the entire principal amount thereof is to be converted, the portion
thereof to be converted.  Securities surrendered for conversion during the
period from the close of business on any Regular Record Date next preceding any
Interest Payment Date to the opening of business on such Interest Payment Date
shall (except in the case of Securities or portions thereof which have been





                                      -80-
<PAGE>   91
called for redemption on a Redemption Date within such period) be accompanied
by payment in funds acceptable to the Company of an amount equal to the
interest payable on such Interest Payment Date on the principal amount of
Securities being surrendered for conversion.  Except as provided in the
preceding sentence and subject to the last paragraph of Section 307, no payment
or adjustment shall be made upon any conversion on account of any interest
accrued on the Securities surrendered for conversion or on account of any
dividends on the Common Stock issued upon conversion.

      Securities shall be deemed to have been converted immediately prior to
the close of business on the day of surrender of such Securities for conversion
in accordance with the foregoing provisions, and at such time the rights of the
Holders of such Securities as Holders shall cease, and the Person or Persons
entitled to receive the Common Stock issuable upon conversion shall be treated
for all purposes as the record holder or holders of such Common Stock at such
time.  As promptly as practicable on or after the conversion date, the Company
shall issue and shall deliver at such office or agency a certificate or
certificates for the number of full shares of Common Stock issuable upon
conversion, together with payment in lieu of any fraction of a share, as
provided in Section 1504.

      In the case of any Security of a series which is converted in part only,
upon such conversion the Company shall execute and the Trustee shall
authenticate and deliver to the Holder thereof, at the expense of the Company,
a new Security or Securities of such series of authorized denominations in
aggregate principal amount equal to the unconverted portion of the principal
amount of such Security.

SECTION 1504. Fractions of Shares.

      No fractional shares of Common Stock shall be issued upon conversion of
Securities.  If more than one Security of a series shall be surrendered for
conversion at one time by the same Holder, the number of full shares which
shall be issuable upon conversion thereof shall be computed on the basis of the
aggregate principal amount of the Securities of such series (or specified
portions thereof) so surrendered.  Instead of any fractional share of Common
Stock which would otherwise be issuable upon conversion of any Security or
Securities (or specified portion thereof), the Company shall pay a cash
adjustment in respect of such fraction in an amount equal (computed to the
nearest cent) to the same fraction of the market price per share of Common
Stock (as determined by the Board of Directors or in any manner prescribed by
the Board of Directors) at the close of business on the day of conversion.

SECTION 1505. Adjustment of Conversion Price.

      (1)  In case at any time after the date of establishment of the Initial
Conversion Price with respect to Securities of a series the Company shall pay
or make a dividend or other distribution in shares of Common Stock on any class
of capital stock of the Company, the conversion price in effect at the opening
of business on the day following the date fixed for the determination of
stockholders entitled to receive such dividend or





                                      -81-
<PAGE>   92
other distribution shall be reduced by multiplying such conversion price by a
fraction of which the numerator shall be the number of shares of Common Stock
outstanding at the close of business on the date fixed for such determination
and the denominator shall be the sum of such number of shares and the total
number of shares constituting such dividend or other distribution, such
reduction to become effective immediately after the opening of business on the
day following the date fixed for such determination.  For the purposes of this
paragraph, the number of shares of Common Stock at any time outstanding shall
not include shares held in the treasury of the Company.  The Company will not
pay any dividend or make any distribution on shares of Common Stock held in the
treasury of the Company.

      (2)  In case at any time after the date of establishment of the Initial
Conversion Price with respect to Securities of a series the Company shall issue
rights or warrants to all holders of its Common Stock entitling them to
subscribe for or purchase shares of Common Stock at a price per share less than
the current market price per share (determined as provided in paragraph (6) of
this Section) of the Common Stock on the date fixed for the determination of
stockholders entitled to receive such rights or warrants, the conversion price
in effect at the opening of business on the day following the date fixed for
such determination shall be reduced by multiplying such conversion price by a
fraction of which the numerator shall be the number of shares of Common Stock
outstanding at the close of business on the date fixed for such determination
plus the number of shares of Common Stock which the aggregate of the offering
price of the total number of shares of Common Stock so offered for subscription
or purchase would purchase at such current market price and the denominator
shall be the number of shares of Common Stock outstanding at the close of
business on the dated fixed for such determination plus the number of shares of
Common Stock so offered for subscription or purchase, such reduction to become
effective immediately after the opening of business on the day following the
date fixed for such determination.  For the purposes of this paragraph (2), the
number of shares of Common Stock at any time outstanding shall not include
shares held in the treasury of the Company.  The Company will not issue any
rights or warrants in respect of shares of Common Stock held in the treasury of
the Company.

      (3)  In case at any time after the date of establishment of the Initial
Conversion Price with respect to Securities of a series outstanding shares of
Common Stock shall be subdivided into a greater number of shares of Common
Stock, the conversion price in effect at the opening of business on the day
following the day upon which such subdivision becomes effective shall be
proportionately reduced, and, conversely, in case outstanding shares of Common
Stock shall each be combined into a smaller number of shares of Common Stock,
the conversion price in effect at the opening of business on the day following
the day upon which such combination becomes effective shall be proportionately
increased, such reduction or increase, as the case may be, to become effective
immediately after the opening of business on the day following the day upon
which such subdivision or combination becomes effective.





                                      -82-
<PAGE>   93
      (4)  In case at any time after the date of establishment of the Initial
Conversion Price with respect to Securities of a series the Company shall, by
dividend or otherwise, distribute to all holders of its Common Stock evidences
of its indebtedness or assets (including securities, but excluding any rights
or warrants referred to in paragraph (2) of this Section, any dividend or
distribution paid in cash out of the retained earnings of the Company and any
dividend or distribution referred to in paragraph (1) of this Section), the
conversion price shall be adjusted so that the same shall equal the price
determined by multiplying the conversion price in effect immediately prior to
the close of business on the date fixed for the determination of stockholders
entitled to receive such distribution by a fraction of which the numerator
shall be the current market price per share (determined as provided in
paragraph (6) of this Section) of the Common Stock on the date fixed for such
determination less the then fair market value (as determined by the Board of
Directors, whose determination shall be conclusive and described in a Board
Resolution filed with the Trustee) of the portion of assets or evidences of
indebtedness so distributed applicable to one share of Common Stock and the
denominator shall be such current market price per share of the Common Stock,
such adjustment to become effective immediately prior to the opening of
business on the day following the date fixed for the determination of
stockholders entitled to receive such distribution.

      (5)  The reclassification of Common Stock into securities other than
Common Stock (other than any reclassification upon a consolidation or merger to
which Section 1502 applies) shall be deemed to involve (a) a distribution of
such securities other than Common Stock to all holders of Common Stock (and the
effective date of such reclassification shall be deemed to be "the date fixed
for the determination of stockholders entitled to receive such distribution"
and "the date fixed for such determination" within the meaning of paragraph (4)
of this Section), and (b) a subdivision or combination, as the case may be, of
the number of shares of Common Stock outstanding immediately prior to such
reclassification into the number of shares of Common Stock outstanding
immediately thereafter (and the effective date of such reclassification shall
be deemed to be "the day upon which such subdivision becomes effective" or "the
day upon which such combination becomes effective", as the case may be, and
"the day upon which such subdivision or combination becomes effective" within
the meaning of paragraph (3) of this Section).

      (6)  For the purpose of any computation under paragraphs (2) and (4) of
this Section, the current market price per share of Common Stock on any date
shall be deemed to be the average of the daily closing prices for the 30
consecutive Business Days selected by the Company commencing not less than 30
nor more than 45 Business Days before the day in question.  The closing price
for each day shall be the last reported sales price regular way or, in case no
such reported sale takes place on such day, the average of the reported closing
bid and asked prices regular way, in either case on the New York Stock Exchange
or, if the Common Stock is not listed or admitted to trading on such Exchange,
on the principal national securities exchange on which the Common Stock is
listed or admitted to trading or, if not listed or admitted to trading on any
national securities exchange, on the National Association of Securities Dealers
Automated Quotations National Market System or, if the Common Stock is not
listed or admitted to





                                      -83-
<PAGE>   94
trading on any national securities exchange or quoted on such National Market
System, the average of the closing bid and asked prices in the over-the-counter
market as furnished by any New York Stock Exchange member firm selected from
time to time by the Company for that purpose.

      (7)  No adjustment in the conversion price shall be required unless such
adjustment would require an increase or decrease of at least 1% in such price;
provided, however, that any adjustment which by reason of this paragraph (7) is
not required to be made shall be carried forward and taken into account in any
subsequent adjustment; and provided, further that all such adjustments shall be
made no later than the third anniversary of the earliest date on which an
adjustment would have been made but for this paragraph (7) and all calculations
under this paragraph (7) shall be made to the nearest cent.

      (8)  The Company may make such reductions in the conversion price, in
addition to those required by paragraphs (1), (2), (3) and (4) of this Section,
as it considers to be advisable in order that any event treated for Federal
income tax purposes as a dividend of stock or stock rights shall not be taxable
to the recipients.

SECTION 1506.  Notice of Adjustments of Conversion Price.

      Whenever the conversion price is adjusted as herein provided:

         (a)  the Company shall compute the adjusted conversion price in
      accordance with Section 1506 and shall prepare a certificate signed by
      the Treasurer of the Company setting forth the adjusted conversion price
      and showing in reasonable detail the facts upon which such adjustment is
      based, and such certificate shall forthwith be filed at each office or
      agency maintained for the purpose of conversion of Securities pursuant to
      Section 1002; and

         (b)  a notice stating that the conversion price has been adjusted and
      setting forth the adjusted conversion price shall forthwith be required,
      and as soon as practicable after it is required, such notice shall be
      mailed by the Company to all Holders at their respective last addresses
      as they shall appear in the Security Register.

SECTION 1507.  Notice of Certain Corporate Action.

      In case at any time after 20 Business Days preceding the Initial
Conversion Date:

         (a)  the Company shall declare a dividend (or any other distribution)
      on its Common Stock payable otherwise than in cash out of its retained
      earnings; or

         (b)  the Company shall authorize the granting to the holders of its
      Common Stock of rights or warrants to subscribe for or purchase any
      shares of capital stock of any class or of any other rights; or





                                      -84-
<PAGE>   95
         (c)  of any reclassification of the Common Stock of the Company (other
      than a subdivision or combination of its outstanding shares of Common
      Stock), or of any consolidation or merger to which the Company is a party
      and for which approval of any stockholders of the Company is required, or
      of the sale or transfer of all or substantially all of the assets of the
      Company; or

         (d)  of the voluntary or involuntary dissolution, liquidation or
      winding up of the Company;

then the Company shall cause to be filed at each office or agency maintained
for the purpose of conversion of Securities pursuant to Section 1002, and shall
cause to be mailed to all Holders at their respective last addresses as they
shall appear in the Security Register, at least 20 days (or 10 days in any case
specified in Clause (a) or (b) above) prior to the applicable record or
effective date hereinafter specified, a notice stating (x) the date on which a
record is to be taken for the purpose of such dividend, distribution, rights or
warrants, or, if a record is not to be taken, the date as of which the holders
of Common Stock of record to be entitled to such dividend, distribution, rights
or warrants are to be determined, or (y) the date on which such
reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding up is expected to become effective, and the date as of
which it is expected that holders of Common Stock of record shall be entitled
to exchange their shares of Common Stock for securities, cash or other
property deliverable upon such reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation or winding up.

SECTION 1508.  Company to Reserve Common Stock.

      The Company shall at all times reserve and keep available, free from
pre-emptive rights, out of its authorized but unissued Common Stock, for the
purpose of effecting the conversion of Securities, the full number of shares of
Common Stock then issuable upon the conversion of all outstanding Securities.

SECTION 1509.  Taxes on Conversions.

      The Company will pay any and all taxes that may be payable in respect of
the issue or delivery of shares of Common Stock on conversion of Securities
pursuant hereto.  The Company shall not, however, be required to pay any tax
which may be payable in respect of any transfer involved in the issue and
delivery of shares of Common Stock in a name other than that of the Holder of
the Security or Securities to be converted, and no such issue or delivery shall
be made unless and until the Person requesting such issue has paid to the
Company the amount of any such tax, or has established to the satisfaction of
the Company that such tax has been paid.

SECTION 1510.  Covenant as to Common Stock.

      The Company covenants that all shares of Common Stock which may be issued
upon conversion of Securities will upon issue be fully paid and nonassessable
and, except





                                      -85-
<PAGE>   96
as provided in Section 1509, the Company will pay all taxes, liens and charges
with respect to the issue thereof.

      The Company covenants that if any shares of Common Stock to be provided
for the purpose of conversion of Securities hereunder require registration with
or approval of any governmental authority under any Federal or State law before
such shares may be validly delivered upon conversion, the Company will in good
faith and as expeditiously as possible endeavor to secure such registration or
approval, as the case may be.

SECTION 1511.  Cancellation of Converted Securities.

      All Securities delivered for conversion shall be delivered to the Trustee
to be cancelled by or at the direction of the Trustee, which shall dispose of
the same as provided in Section 309.

SECTION 1512.  Provisions in Case of Consolidation, Merger or Sale of Assets.

      In case of any consolidation of the Company with, or merger of the
Company into, any other Person, any merger of another Person into the Company
(other than a merger which does not result in any reclassification, conversion,
exchange or cancellation of outstanding shares of Common Stock of the Company)
or any sale or transfer of all or substantially all of the assets of the
Company, the Person formed by such consolidation or resulting from such merger
or which acquires such assets, as the case may be, shall execute and deliver to
the Trustee a supplemental indenture providing that the Holder of each Security
then outstanding shall have the right thereafter, during the period such
Security shall be convertible as specified in Section 1502, to convert such
Security only into the kind and amount of securities, cash and other property
receivable upon such consolidation, merger, sale or transfer by a holder of the
number of shares of Common Stock of the Company into which such Security might
have been converted immediately prior to such consolidation, merger, sale or
transfer, assuming such holder of Common Stock of the Company (i) is not a
Person with which the Company consolidated or into which the Company merged or
which merged into the Company or to which such sale or transfer was made, as
the case may be ("constituent Person"), or an Affiliate of a constituent Person
and (ii) failed to exercise his rights of election, if any, as to the kind or
amount of securities, cash and other property receivable upon such
consolidation, merger, sale or transfer (provided that if the kind or amount of
securities, cash and other property receivable upon such consolidation, merger,
sale or transfer is not the same for each share of Common Stock of the Company
held immediately prior to such consolidation, merger, sale or transfer by
others than a constituent Person or an Affiliate thereof and in respect of
which such rights of election shall not have been exercised ("non-electing
share"), then for the purpose of this Section the kind and amount of
securities, cash and other property receivable upon such consolidation, merger,
sale or transfer by each non-electing share shall be deemed to be the kind and
amount so receivable per share by a plurality of the non-electing shares), and
assuming, if such consolidation, merger, sale or transfer is prior to the
Initial Conversion Date, that the Securities were convertible at the time of
such consolidation, merger, sale or transfer at the initial





                                      -86-
<PAGE>   97
conversion price specified in Section 1502 as adjusted from the date of
establishment of the Initial Conversion Price with respect to Securities of a
series to such time pursuant to paragraphs (1), (2), (3), (4) and (7) of
Section 1505.  Such supplemental indenture shall provide for adjustments which,
for events subsequent to the effective date of such supplemental indenture,
shall be as nearly equivalent as may be practicable to the adjustments provided
for in this Article.  The above provisions of this Section shall similarly
apply to successive consolidations, mergers, sales or transfers.

SECTION 1513.  Responsibility of Trustee.

      The Trustee shall not at any time be under any duty or responsibility to
any Holder of a Security to make or cause to be made any adjustment of the
conversion price, or to determine whether any facts exist which may require any
such adjustment, or with respect to the nature or extent of any such adjustment
when made, or with respect to any method employed, or herein or in any
supplemental indenture provided to be employed, in making the same.  The
Trustee shall not be accountable with respect to the validity or value (or the
kind or amount) of any shares of Common Stock or of any securities or property
which may at any time be issued or delivered upon conversion of any Security;
and the Trustee makes no representation with respect thereto.  The Trustee
shall not be responsible for any failure of the Company to issue, transfer or
deliver any shares of Common Stock or stock certificates or other securities or
property upon surrender of any Security for the purpose of conversion or to
comply with any of the covenants of the Company contained in this Article
Fifteen.

                               _________________
      This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

                     SURRENDER AND REDEMPTION OF RECEIPTS

        SECTION 2.01.  Form and Transfer of Receipts.  Definitive Receipts
shall be engraved or printed or lithographed and shall be substantially in the
form set forth in Exhibit A annexed to this Deposit Agreement, with appropriate
insertions, modifications and omissions, as hereinafter provided.  Pending the
preparation of definitive Receipts, the Depositary, upon the written order of
the Company delivered in compliance with Section 2.02, shall execute and
deliver temporary Receipts which are printed, lithographed, typewritten,
mimeographed or otherwise substantially of the tenor of the definitive Receipts
in lieu of which they are issued and with such appropriate insertions,

unreasonable delay.  After the preparation of definitive Receipts, the

charge therefor.  Until so exchanged, the temporary Receipts shall in all
respects be entitled to the same benefits under this Deposit Agreement, and
with respect to the Stock, as definitive Receipts.

        Receipts shall be executed by the Depositary by the manual signature of
a duly authorized officer of the Depositary;provided, that such signature may
be a facsimile if a Registrar for the Receipts (other than the Depositary)
shall have been appointed and such Receipts are countersigned by manual
signature of a duly authorized officer of the Registrar.  No Receipt shall be
entitled to any benefits under this Deposit Agreement or be valid or obligatory

authorized officer of the Depositary or, if a Registrar for the Receipts (other
than the Depositary) shall have been appointed, by facsimile signature of a
duly authorized officer of the Depositary and countersigned manually by a duly
authorized officer of such Registrar.  The Depositary shall record on its books
each Receipt so signed and delivered as hereinafter provided.

        Receipts may be endorsed with or have incorporated in the text thereof
such legends or recitals or changes not inconsistent with the provisions of
this Deposit Agreement as may be required by the Company or the Depositary or
required to comply with any applicable law or any regulation thereunder or with
the rules and regulations of any securities exchange upon which the Stock, the
Depositary Shares or the Receipts may be listed or to conform with any usage
with respect thereto, or to indicate any special limitations or restrictions to
which any particular Receipts are subject.

        Title to Depositary Shares evidenced by a Receipt which is properly
endorsed, or accompanied by a properly executed instrument of transfer, shall
be transferable by delivery with the same effect as in the case of a negotiable
instrument; provided, however, that until transfer of a Depositary Share shall
be registered on the books of the





                                      -3-


<PAGE>   4
Depositary as provided in Section 2.04, the Depositary may, notwithstanding any
notice to the contrary, treat the Record Holder thereof at such time as the
absolute owner thereof for the purpose of determining the person entitled to
distributions of dividends or other distributions or to any notice provided for
in this Deposit Agreement and for all other purposes.

        SECTION 2.02.  Deposit of Stock; Execution and Delivery of Receipts in
Respect Thereof.  Subject to the terms and conditions of this Deposit
Agreement, the Company may from time to time deposit shares of Stock under this
Deposit Agreement by delivery to the Depositary of a certificate or
certificates for the Stock to be deposited, properly endorsed or accompanied,
if required by the Depositary, by a duly executed instrument of transfer or
endorsement, in form satisfactory to the Depositary, together with all such
certifications as may be required by the Depositary in accordance with the
provisions of this Deposit Agreement, and together with a written order of the
Company directing the Depositary to execute and deliver to, or upon the written
order of, the person or persons stated in such order a Receipt or Receipts for
the number of Depositary Shares relating to such deposited Stock.

        Deposited Stock shall be held by the Depositary at the Depositary's
Office or at such other place or places as the Depositary shall determine.

        Upon receipt by the Depositary of a certificate or certificates for
Stock deposited in accordance with the provisions of this Section, together
with the other documents required as above specified, and upon recordation of
the Stock so deposited on the books of the Company in the name of the
Depositary or its nominee, the Depositary, subject to the terms and conditions
of this Deposit Agreement, shall execute and deliver, to or upon the order of
the person or persons named in the written order delivered to the Depositary
referred to in the first paragraph of this Section, a Receipt or Receipts for
the number of Depositary Shares relating to the Stock so deposited and
registered in such name or names as may be requested by such person or persons.
The Depositary shall execute and deliver such Receipt or Receipts at the
Depositary's Office or such other offices, if any, as the Depositary may
designate.  Delivery at other offices shall be at the risk and expense of the
person requesting such delivery.

        Other than in the case of splits, combinations or other
reclassifications affecting the Stock, or in the case





                                      -4-


<PAGE>   5
of dividends or other distributions of Stock, if any, there shall be deposited
hereunder not more than ____________________ shares of Stock.

        SECTION 2.03.  Redemption of Stock.  Whenever the Company shall elect
to redeem shares of Stock in accordance with the provisions of the Articles of
Amendment, it shall (unless otherwise agreed in writing with the Depositary)
mail notice to the Depositary of such proposed redemption, by first class mail,
postage prepaid not less than 40 or more than 70 days prior to the date fixed
for redemption of Stock in accordance with Section ___ of the Articles of
Amendment.  On the date of such redemption, provided that the Company shall
then have paid in full to the Depositary the redemption price of the Stock to
be redeemed, plus any accrued and unpaid dividends thereon, the Depositary
shall redeem the Depositary Shares relating to such Stock.  The Depositary
shall mail notice of such redemption and the proposed simultaneous redemption
of the number of Depositary Shares relating to the Stock to be redeemed, by
first-class mail, postage prepaid, not less than 30 and not more than 60 days
prior to the date fixed for redemption of such Stock and Depositary Shares (the
"Redemption Date"), to the Record Holders of the Depositary Shares to be so
redeemed, at the addresses of such holders as they appear on the records of the
Depositary; but neither failure to mail any such notice to one or more such
holders nor any defect in any notice to one or more such holders shall affect
the sufficiency of the proceedings for redemption as to other holders.  Each
such notice shall state: (i) the Redemption Date; (ii) the number of Depositary
Shares to be redeemed and, if fewer than all the Depositary Shares held by any
such holder are to be redeemed, the number of such Depositary Shares held by
such holder to be so redeemed; (iii) the redemption price; (iv) the place or
places where Receipts evidencing Depositary Shares are to be surrendered for
payment of the redemption price; and (v) that dividends in respect of the Stock
underlying the Depositary Shares to be redeemed will cease to accrue and
accumulate at the close of business on such Redemption Date.  In case less than
all the outstanding Depositary Shares are to be redeemed, the Depositary Shares
to be so redeemed shall be selected by lot or pro rata as may be determined by
the Depositary to be equitable.

        Notice having been mailed by the Depositary as aforesaid, from and
after the Redemption Date (unless the Company shall have failed to redeem the
shares of Stock to be redeemed by it as set forth in the Company's notice
provided for in the preceding paragraph) all dividends in respect of the
Depositary Shares so called for redemption shall cease to accrue and
accumulate, the Depositary Shares





                                      -5-


<PAGE>   6
being redeemed from such proceeds shall be deemed no longer to be outstanding,
all rights of the holders of Receipts evidencing such Depositary Shares (except
the right to receive the redemption price) shall, to the extent of such
Depositary Shares, cease and terminate and, upon surrender in accordance with
such notice of the Receipts evidencing any such Depositary Shares (properly
endorsed or assigned for transfer, if the Depositary shall so require), such
Depositary Shares shall be redeemed by the Depositary at a redemption price per
Depositary Share equal to the proportionate part of the redemption price per
share paid in respect of the shares of Stock plus all money and other property,
if any, paid with respect to such Depositary Shares, including all amounts paid
by the Company in respect of dividends which on the Redemption Date have
accumulated on the shares of Stock to be so redeemed and have not theretofore
been paid.  The foregoing shall be subject further to the terms and conditions
of the Articles of Amendment.

        If fewer than all the Depositary Shares evidenced by a Receipt are
called for redemption, the Depositary will deliver to the holder of such
Receipt upon its surrender to the Depositary, together with the redemption
payment, a new Receipt evidencing the Depositary Shares evidenced by such prior
Receipt and not called for redemption.

        SECTION 2.04.  Registration of Transfer of Receipts.  Subject to the
terms and conditions of this Deposit Agreement, the Depositary shall register
on its books from time to time transfers of Depositary Shares upon any
surrender of the Receipt or Receipts evidencing such Depositary Shares by the
holder in person or by a duly authorized attorney, properly endorsed or
accompanied by a properly executed instrument of transfer.  Thereupon the
Depositary shall execute a new Receipt or Receipts evidencing the same
aggregate number of Depositary Shares as those evidenced by the Receipt or
Receipts surrendered and deliver such new Receipt or Receipts to or upon the
order of the person entitled thereto.

        SECTION 2.05.  Split-ups and Combinations of Receipts; Surrender of
Depositary Shares and Withdrawal of Stock.  Upon surrender of a Receipt or
Receipts at the Depositary's Office or at such other offices as it may
designate for the purpose of effecting a split-up or combination of such
Receipt or Receipts, and subject to the terms and conditions of this Deposit
Agreement, the Depositary shall execute and deliver a new Receipt or Receipts
in the denominations requested, evidencing the





                                      -6-


<PAGE>   7
aggregate number of Depositary Shares evidenced by the Receipt or Receipts
surrendered.

        Any holder of Depositary Shares may withdraw the number of whole shares
of Stock underlying such Depositary Shares and all money and other property, if
any, underlying such Depositary Shares by surrendering Receipts evidencing such
Depositary Shares at the Depositary's Office or at such other offices as the
Depositary may designate for such withdrawals.  Thereafter, without
unreasonable delay, the Depositary shall deliver to such holder, or to the
person or persons designated by such holder as hereinafter provided, the number
of whole shares of Stock and all money and other property, if any, underlying
the Depositary Shares so surrendered for withdrawal, but holders of such whole
shares of Stock will not thereafter be entitled to deposit such Stock hereunder
or to receive Receipts evidencing Depositary Shares therefor.  If a Receipt
delivered by a holder to the Depositary in connection with such withdrawal
shall evidence a number of Depositary Shares relating to other than a number of
whole shares of Stock, the Depositary shall at the same time, in addition to
such number of whole shares of Stock and such money and other property, if any,
to be so withdrawn, deliver to such holder, or (subject to Section 3.02) upon
his order, a new Receipt evidencing such excess number of Depositary Shares.
Delivery of the Stock and money and other property being withdrawn may be made
by delivery of such certificates, documents of title and other instruments as
the Depositary may deem appropriate.

        If the Stock and the money and other property being withdrawn are to be
delivered to a person or persons other than the Record Holder of the Depositary
Shares evidenced by the Receipts being surrendered for withdrawal of Stock,
such holder shall execute and deliver to the Depositary a written order so
directing the Depositary, and the Depositary may require that the Receipt or
Receipts surrendered by such holder for withdrawal of such shares of Stock be
properly endorsed in blank or accompanied by a properly executed instrument of
transfer.

        Delivery of the Stock and money and other property, if any, underlying
the Depositary Shares surrendered for withdrawal shall be made by the
Depositary at the Depositary's Office, except that, at the request, risk and
expense of the holder surrendering such Depositary Shares and for the account
of such holder, such delivery may be made at such other place as may be
designated by such holder.

        SECTION 2.06.  Limitations on Execution and Delivery, Transfer,
Surrender and Exchange of Receipts.  As a condition precedent to the execution
and delivery, registration of transfer, split-up, combination, surrender or
exchange of any Receipt, the Depositary, any of the Depositary's Agents or the
Company may require payment to it of a sum sufficient for the payment (or, in
the event that the Depositary or the Company shall have made such payment, the
reimbursement to it) of any charges or expenses payable by the holder of a
Receipt pursuant to Section 5.07, may require the production of evidence
satisfactory to it as to the identity and genuineness of any signature and may
also require compliance with such regulations, if any, as the Depositary or the
Company may establish consistent with the provisions of this Deposit Agreement.

        The delivery of Receipts against Stock may be suspended, the
registration of transfer of Depositary Shares may be refused and the
registration of transfer, surrender or exchange of outstanding Depositary
Shares may be suspended (i) during any period when the register of stockholders
of the Company is closed or (ii) if any such action is deemed necessary or
advisable by the Depositary, any of the Depositary's Agents or the Company at
any time or from time to time because of any requirement of law or of any
government or governmental body or commission or under any provision of this
Deposit Agreement.

        SECTION 2.07.  Lost Receipts, etc.  In case any Receipt shall be
mutilated, destroyed, lost or stolen, the Depositary in its discretion may
execute and deliver a Receipt of like form and tenor in exchange and
substitution for such mutilated Receipt, or in lieu of and in substitution for
such destroyed, lost or stolen Receipt, upon (i) the filing by the holder
thereof with the Depositary of evidence satisfactory to the Depositary of such
destruction or loss or theft of such Receipt, or the authenticity thereof and
of his or her ownership thereof and (ii) the furnishing of the Depositary with
reasonable indemnification satisfactory to it.

        SECTION 2.08.  Cancellation and Destruction of Surrendered Receipts.
All Receipts surrendered to the Depositary or any Depositary's Agent shall be
canceled by the Depositary.  Except as prohibited by applicable law or
regulation, the Depositary is authorized to destroy all Receipts so canceled.

                       CERTAIN OBLIGATIONS OF THE HOLDERS
                          OF RECEIPTS AND THE COMPANY

        SECTION 3.01.  Filing Proofs, Certificates and Other Information.  Any
holder of a Depositary Share may be required from time to time to file such
proof of residence, or other matters or other information, to execute such
certificates and to make such representations and warranties as the Depositary
or the Company may reasonably deem necessary or proper.  The Depositary or the
Company may withhold the delivery, or delay the registration of transfer,
redemption or exchange, of any Depositary Share or the withdrawal of any Stock
underlying Depositary Shares or the distribution of any dividend or other
distribution or the sale of any rights or of the proceeds thereof until such
proof or other information is filed or such certificates are executed or such
representations and warranties are made.

        SECTION 3.02.  Payment of Taxes or Other Governmental Charges.  Holders
of Depositary Shares shall be obligated to make payments to the Depositary of
certain charges and expenses, as provided in Section 5.07.  Registration of
transfer of any Depositary Share or any withdrawal of Stock and delivery of all
money or other property, if any, underlying such Depositary Share may be
refused until any such payment due is made, and any dividends or other
distributions may be withheld or all or any part of the Stock or other property
relating to such Depositary Shares and not theretofore sold may be sold for the
account of the holder thereof (after attempting by reasonable means to notify
such holder prior to such sale), and such dividends or other distributions or
the proceeds of any such sale may be applied to any payment of such charges or
expenses, the holder of such Depositary Share remaining liable for any
deficiency.  The Depositary shall act as the withholding agent for any
payments, distributions and exchanges made with respect to the Depositary
Shares and Receipts, and the Stock or other securities or assets represented
thereby (collectively, the "Securities").  The Depositary shall be responsible
with respect to the Securities for the timely (i) collection and deposit of any
required withholding or backup withholding tax, and (ii) filing of any
information returns or other documents with federal (and other applicable)
taxing authorities.  In the event the Depositary is required to pay any such
amounts, the Company shall reimburse the Depositary for payment thereof upon
the request of the Depositary and the Depositary shall, upon the Company's
request and as





                                      -9-

instructed by the Company, pursue its rights against such holder at the
Company's expense.

        SECTION 3.03.  Warranty as to Stock.  The Company hereby represents and
warrants that the Stock, when issued, will be validly issued, fully paid and
nonassessable.  Such representation and warranty shall survive the deposit of
the Stock and the issuance of the Receipts.


                                   ARTICLE IV

                       THE DEPOSITED SECURITIES; NOTICES

        SECTION 4.01.  Cash Distributions.  Whenever the Depositary shall
receive any cash dividend or other cash distribution on the Stock, the
Depositary shall, subject to Sections 3.01 and 3.02, distribute to the Record
Holders of Depositary Shares on the record date fixed pursuant to Section 4.04
such amounts of such dividend or distribution as are, as nearly as practicable,
in proportion to the respective numbers of Depositary Shares held by such
holders;provided, however, that in case the Company or the Depositary shall be
required to withhold and shall withhold from any cash dividend or other cash
distribution in respect of the Stock an amount on account of taxes or as
otherwise required pursuant to law, regulation or court process, the amount
made available for distribution or distributed in respect of Depositary Shares
shall be reduced accordingly.  The Depositary shall distribute or make
available for distribution, as the case may be, 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 distributable shall be held by the
Depositary (without liability for interest thereon) and shall be added to and
be treated as part of the next sum received by the Depositary for distribution
to Record Holders of Depositary Shares then outstanding.

        SECTION 4.02.  Distributions Other than Cash.  Whenever the Depositary
shall receive any distribution other than cash on the Stock, the Depositary
shall, subject to Sections 3.01 and 3.02, distribute to the Record Holders of
Depositary Shares on the record date fixed pursuant to Section 4.04 such
amounts of the securities or property received by it as are, as nearly as
practicable, in proportion to the respective numbers of Depositary Shares held
by such holders, in any manner that the Depositary may deem equitable and
practicable for accomplishing such distribution.  If in the opinion of the
Depositary such distribution cannot be made proportionately among such





                                      -10-


<PAGE>   11
Record Holders, or if for any other reason (including any requirement that the
Company or the Depositary withhold an amount on account of taxes or
governmental charges) the Depositary deems, after consultation with the
Company, such distribution not to be feasible, the Depositary may, with the
approval of the Company, adopt such method as it deems equitable and
practicable for the purpose of effecting such distribution, including the sale
(at public or private sale) of the securities or property thus received, or any
part thereof, at such place or places and upon such terms as it may deem
proper.  The net proceeds of any such sale shall, subject to Sections 3.01 and
3.02, be distributed or made available for distribution, as the case may be, by
the Depositary to the Record Holders of Depositary Shares entitled thereto as
provided by Section 4.01 in the case of a distribution received in cash.  The
Company shall not make any distribution of such securities unless the Company
shall have provided an opinion of counsel to the effect that such securities
have been registered under the Securities Act of 1933 or do not need to be
registered.

        SECTION 4.03.  Subscription Rights, Preferences or Privileges.  If the
Company shall at any time offer or cause to be offered to the persons in whose
names Stock is recorded on the books of the Company any rights, preferences or
privileges to subscribe for or to purchase any securities or any rights,
preferences or privileges of any other nature, such rights, preferences or
privileges shall in each such instance be made available by the Depositary to
the Record Holders of Depositary Shares in such manner as the Depositary may
determine, either by the issue to such Record Holders of warrants representing
such rights, preferences or privileges or by such other method as may be
approved by the Depositary in its discretion with the approval of the
Company;provided, however, that (i) if at the time of issue or offer of any
such rights, preferences or privileges the Depositary determines that it is not
lawful or (after consultation with the Company) not feasible to make such
rights, preferences or privileges available to holders of Depositary Shares by
the issue of warrants or otherwise, or (ii) if and to the extent so instructed
by holders of Depositary Shares who do not desire to exercise such rights,
preferences or privileges, then the Depositary, in its discretion (with the
approval of the Company, in any case where the Depositary has determined that
it is not feasible to make such rights, preferences or privileges available),
may, if applicable laws or the terms of such rights, preferences or privileges
permit such transfer, sell such rights, preferences or privileges at public or
private sale, at such place or places and upon such terms as it may deem
proper.  The net proceeds of any such sale shall, subject to





                                      -11-


<PAGE>   12
Sections 3.01 and 3.02, be distributed by the Depositary to the Record Holders
of Depositary Shares entitled thereto as provided by Section 4.01 in the case
of a distribution received in cash.  The Company shall not make any
distribution of such rights, preferences or privileges unless the Company shall
have provided an opinion of counsel to the effect that such rights, preferences
or privileges have been registered under the Securities Act of 1933 or do not
need to be registered.

        If registration under the Securities Act of 1933 of the securities to
which any rights, preferences or privileges relate is required in order for
holders of Depositary Shares to be offered or sold the securities to which such
rights, preferences or privileges relate, the Company agrees with the
Depositary that it will file promptly a registration statement pursuant to such
Act with respect to such rights, preferences or privileges and securities and
use its best efforts and take all steps available to it to cause such
registration statement to become effective sufficiently in advance of the
expiration of such rights, preferences or privileges to enable such holders to
exercise such rights, preferences or privileges.  In no event shall the
Depositary make available to the holders of Depositary Shares any right,
preference or privilege to subscribe for or to purchase any securities unless
and until such a registration statement shall have become effective, or unless
the offering and sale of such securities to such holders are exempt from
registration under the provision of such Act.

        If any other action under the laws of any jurisdiction or any
governmental or administrative authorization, consent or permit is required in
order for such rights, preferences or privileges to be made available to the
holders of Depositary Shares, the Company agrees with the Depositary that the
Company will use its best efforts to take such action or obtain such
authorization, consent or permit sufficiently in advance of the expiration of
such rights, preferences or privileges to enable such holders to exercise such
rights, preferences or privileges.

        SECTION 4.04.  Notice of Dividends, etc.; Fixing of Record Date for
Holders of Depositary Shares.  Whenever any cash dividend or other cash
distribution shall become payable or any distribution other than cash shall be
made, or if rights, preferences or privileges shall at any time be offered,
with respect to the Stock, or whenever the Depositary shall receive notice of
any meeting at which holders of Stock are entitled to vote or any solicitation
of consents in respect of the Stock or any call for redemption





                                      -12-


<PAGE>   13
of any shares of Stock, or of which holders of Stock are entitled to notice,
the Depositary shall in each such instance fix a record date (which shall be
the same date as the record date fixed by the Company with respect to the
Stock) for the determination of the holders of Depositary Shares who shall be
entitled to receive a distribution in respect of such dividend, distribution,
rights, preferences or privileges or the net proceeds of the sale thereof, or
to give instructions for the exercise of voting rights at any such meeting, or
who shall be entitled to receive notice of such meeting or any such call for
redemption.

        SECTION 4.05.  Voting Rights.  Upon receipt of notice of any meeting at
which the holders of the Stock are entitled to vote or any solicitation of
consents in respect of the Stock, the Depositary shall, as soon as practicable
thereafter, mail to the Record Holders of Depositary Shares a notice which
shall contain (i) such information as is contained in such notice of meeting or
consent solicitation and (ii) a statement informing Record Holders of
Depositary Shares that they may instruct the Depositary as to the exercise of
the voting rights pertaining to the amount of Stock underlying their respective
Depositary Shares and a brief statement as to the manner in which such
instructions may be given.  Upon the written request of the holders of
Depositary Shares on the record date established in accordance with Section
4.04, the Depositary shall endeavor insofar as practicable to vote or cause to
be voted, in accordance with the instructions set forth in such requests, the
maximum number of whole shares of Stock underlying the Depositary Shares as to
which any particular voting or consent instructions are received.  The Company
hereby agrees to take all action which may be deemed necessary by the
Depositary in order to enable the Depositary to vote such Stock or cause such
Stock to be voted.  In the absence of specific instructions from the holder of
a Depositary Share, the Depositary will abstain from voting (but, at its
discretion, not from appearing at any meeting with respect to such Stock unless
directed to the contrary by the holders of all the Depositary Shares) to the
extent of the Stock underlying the Depositary Shares.

        SECTION 4.06.  Changes Affecting Deposited Securities and
Reclassifications, Recapitalizations, etc.  Upon any change in par or
liquidation value, split-up, combination or any other reclassification of the
Stock, or upon any recapitalization, reorganization, merger, amalgamation or
consolidation affecting the Company or to which it is a party, the Depositary
may in its discretion, with the approval of, and shall upon the instructions
of, the Company, and (in either case) in such manner as the





                                      -13-


<PAGE>   14
Depositary may deem equitable, (i) make such adjustments in (a) the fraction of
an interest in one share of Stock underlying one Depositary Share and (b) the
ratio of the redemption price per Depositary Share to the redemption price of a
share of the Stock, in each case as may be necessary fully to reflect the
effects of such change in par or liquidation value, split-up, combination or
other reclassification of the Stock, or of such recapitalization,
reorganization, merger, amalgamation or consolidation and (ii) treat any
securities which shall be received by the Depositary in exchange for or upon
conversion of or in respect of the Stock as new deposited securities so
received in exchange for or upon conversion of or in respect of such Stock and
Receipts then outstanding shall thenceforth represent the proportionate
interest of holders thereof in the new deposited property so received in
exchange for or upon conversion of or in respect of such Stock.  In any such
case the Depositary may in its discretion, with the approval of the Company,
execute and deliver additional Receipts, or may call for the surrender of all
outstanding Receipts to be exchanged for new Receipts specifically describing
such new deposited securities.

        SECTION 4.07.  Delivery of Reports.  The Depositary will forward to
Record Holders of Receipts, at their respective addresses appearing in the
Depositary's books, all notices, reports and communications received from the
Company which are delivered to the Depositary and which the Company is required
to furnish to the holders of Stock or Receipts.

        SECTION 4.08.  List of Holders.  Promptly upon request from time to
time by the Company, the Depositary shall furnish to it a list, as of a recent
date, of the names, addresses and holdings of Depositary Shares of all persons
in whose names Depositary Shares are registered on the books of the Depositary
or Registrar, as the case may be.


                                   ARTICLE V

                    THE DEPOSITARY, THE DEPOSITARY'S AGENTS,
                         THE REGISTRAR AND THE COMPANY

        SECTION 5.01.  Maintenance of Offices, Agencies and Transfer Books by
the Depositary; Registrar.  Upon execution of this Deposit Agreement, the
Depositary shall maintain at the Depositary's Offices, or at any Registrar's
Office, at which the Depositary shall have complete access to all books and
records maintained on the Company's behalf,





                                      -14-


<PAGE>   15
facilities for the execution and delivery, surrender and exchange of Receipts
and the registration and registration of transfer of Depositary Shares, and at
the offices of the Depositary's Agents, if any, facilities for the delivery,
surrender and exchange of Receipts and the registration of transfer of
Depositary Shares, all in accordance with the provisions of this Deposit
Agreement.

        The Depositary shall keep books at the Depositary's Office for the
registration and registration of transfer of Depositary Shares, which books at
all reasonable times shall be open for inspection by the Record Holders of
Depositary Shares.  The Depositary may close such books, at any time or from
time to time, when deemed expedient by it in connection with the performance of
its duties hereunder.

        The Depositary shall make available for inspection by holders of
Receipts at the Depositary's Office and at such other places as it may from
time to time deem advisable during normal business hours any reports and
communications received from the Company that are both received by the
Depositary as the holder of Stock and made generally available to the holders
of Stock.

        If the Receipts or the Depositary Shares evidenced thereby or the Stock
underlying such Depositary Shares shall be listed on the New York Stock
Exchange, the Depositary may, with the approval of the Company, appoint a
Registrar for registration of such Receipts or Depositary Shares in accordance
with any requirements of such Exchange.  Such Registrar (which may be the
Depositary if so permitted by the requirements of such Exchange) may be removed
and a substitute registrar appointed by the Depositary upon the request or with
the approval of the Company.  If the Receipts, such Depositary Shares or such
Stock are listed on one or more other stock exchanges, the Depositary will, at
the request of the Company, arrange such facilities for the delivery,
registration, registration of transfer, surrender and exchange of such
Receipts, such Depositary Shares or such Stock as may be required by law or
applicable stock exchange regulation.

        SECTION 5.02.  Prevention of or Delay in Performance by the Depositary,
the Depositary's Agents, any Registrar or the Company.  Neither the Depositary
nor any Depositary's Agent nor any Registrar nor the Company shall incur any
liability to any holder or any Depositary Share if by reason of any provision
of any present or future law, or regulation thereunder, of the United States of
America or of any other governmental authority or, in the case of the
Depositary, any Depositary's Agent or any Registrar, by





                                      -15-


<PAGE>   16
reason of any provision, present or future, of the Company's Restated Charter
(including the Articles of Amendment) or, in the case of the Company, the
Depositary, any Depositary's Agent or any Registrar, by reason of any act of
God or war or other circumstance beyond the control of the relevant party, the
Depositary, any Depositary's Agent, any Registrar or the Company shall be
prevented or forbidden from doing or performing any act or thing which the
terms of this Deposit Agreement provide shall be done or performed; nor shall
the Depositary, any Depositary's Agent, any Registrar or the Company incur any
liability to any holder of a Depositary Share (i) by reason of any
nonperformance or delay, caused as aforesaid, in the performance of any act or
thing which the terms of this Deposit Agreement provide shall or may be done or
performed, or (ii) by reason of any exercise of, or failure to exercise, any
discretion provided for in this Deposit Agreement except, in case of any such
exercise or failure to exercise discretion not caused as aforesaid, if caused
by the negligence, bad faith or willful misconduct of the party charged with
such exercise or failure to exercise.

        SECTION 5.03.  Obligations of the Depositary, the Depositary's Agents,
any Registrar and the Company.  Neither the Depositary nor any Depositary's
Agent nor any Registrar nor the Company assumes any obligation or shall be
subject to any liability under this Deposit Agreement to holders of Depositary
Shares other than that each of them agrees to use good faith in the performance
of such duties as are specifically set forth in this Deposit Agreement and for
its negligence, bad faith or willful misconduct.

        Neither the Depositary nor any Depositary's Agent nor any Registrar nor
the Company shall be under any obligation to appear in, prosecute or defend any
action, suit or other proceeding in respect of the Stock, the Depositary Shares
or the Receipts which in its opinion may involve it in expense or liability
unless indemnity satisfactory to it against all expense and liability be
furnished as often as may be required.

        Neither the Depositary nor any Depositary's Agent nor any Registrar nor
the Company shall be liable for any action or any failure to act by it in
reliance upon the written advice of legal counsel or accountants, or
information from any person presenting Stock for deposit, any holder of a
Depositary Share or any other person believed by it in good faith to be
competent to give such information.  The Depositary, any Depositary's Agent,
any Registrar and the Company may each rely and shall each be protected in
acting upon any written notice, request, direction or other document believed
by it to be genuine and





                                      -16-


<PAGE>   17
to have been signed or presented by the proper party or parties.

        The Depositary shall not be responsible for any failure to carry out
any instruction to vote any of the shares of Stock or for the manner or effect
of any such vote, as long as any such action or non-action is in good faith.
The Depositary undertakes, and any Registrar shall be required to undertake, to
perform such duties and only such duties as are specifically set forth in this
Deposit Agreement.  The Depositary will indemnify the Company against any
liability which may arise out of acts performed or omitted by the Depositary or
its agents due to its or their negligence or bad faith.  The Depositary, the
Depositary's Agents, any Registrar and the Company may own and deal in any
class of securities of the Company and its affiliates and in Depositary Shares.
The Depositary may also act as transfer agent or registrar of any of the
securities of the Company and its affiliates.

        The Depositary hereby represents and warrants as follows: (i) the
Depositary has been duly organized and is validly existing and in good standing
under the laws of the State of ______, with full power, authority and legal
right under such law to execute, deliver and carry out the terms of this
Deposit Agreement; (ii) this Deposit Agreement has been duly authorized,
executed and delivered by the Depositary; and (iii) this Deposit Agreement
constitutes a valid and binding obligation of the Depositary, enforceable
against the Depositary in accordance with its terms, except as enforcement
thereof may be limited by bankruptcy, insolvency, reorganization or other
similar laws affecting enforcement of creditors' rights generally and except as
enforcement thereof is subject to general principles of equity (regardless of
whether enforcement is considered in a proceeding in equity or at law).  The
Depositary shall not be accountable for the use or application by the Company
of the Depositary Shares or the Receipts or the proceeds thereof.

        SECTION 5.04.  Resignation and Removal of the Depositary; Appointment
of Successor Depositary.  The Depositary may at any time resign as Depositary
hereunder by notice of its election so to do delivered to the Company, such
resignation to take effect upon the appointment of a successor Depositary and
its acceptance of such appointment as hereinafter provided.

        The Depositary may at any time be removed by the Company by notice of
such removal delivered to the Depositary, such removal to take effect upon the
appointment





                                      -17-


<PAGE>   18
of a successor Depositary and its acceptance of such appointment as hereinafter
provided.

        In case the Depositary acting hereunder shall at any time resign or be
removed, the Company shall, within 60 days after the delivery of the notice of
resignation or removal, as the case may be, appoint a successor Depositary,
which shall be a bank or trust company having its principal office in the
United States of America and having a combined capital and surplus of at least
$50,000,000.  If no successor Depositary shall have been so appointed within 60
days after delivery of such notice, the resigning or removed Depositary may
petition any court of competent jurisdiction for the appointment of a successor
Depositary.  Every successor Depositary shall execute and deliver to its
predecessor and to the Company an instrument in writing accepting its
appointment hereunder, and thereupon such successor Depositary, without any
further act or deed, shall become fully vested with all the rights, powers,
duties and obligations of its predecessor and for all purposes shall be the
Depositary under this Deposit Agreement, and such predecessor, upon payment of
all sums due it and on the written request of the Company, shall execute and
deliver an instrument transferring to such successor all rights and powers of
such predecessor hereunder, shall duly assign, transfer and deliver all right,
title and interest in the Stock and any moneys or property held hereunder to
such successor and shall deliver to such successor a list of the Record Holders
of all outstanding Depositary Shares.  Any successor Depositary shall promptly
mail notice of its appointment to the Record Holders of Depositary Shares.

        Any corporation into or with which the Depositary may be merged,
consolidated or converted shall be the successor of such Depositary without the
execution or filing of any document or any further act.  Such successor
Depositary may authenticate the Receipts in the name of the predecessor
Depositary or in the name of the successor Depositary.

        SECTION 5.05.  Corporate Notices and Reports.  The Company agrees that
it will transmit to the Depositary, and the Depositary will, promptly after
receipt thereof, transmit to the Record Holders of Depositary Shares, in each
case at the address recorded in the Depositary's books, copies of all notices,
reports and communications (including without limitation financial statements)
required by law, the rules of any national securities exchange upon which the
Stock, the Depositary Shares or the Receipts are listed or by the Company's
Charter (including the Articles of Amendment) to be furnished by the Company to
holders of the





                                      -18-


<PAGE>   19
Stock.  Such transmission will be at the Company's expense and the
Company will provide the Depositary with such number of copies of such
documents as the Depositary may reasonably request.  In addition, the
Depositary will transmit to the Record Holders of Depositary Shares at the
Company's expense such other documents as may be requested by the Company.

        SECTION 5.06.  Indemnification by the Company.  The Company shall
indemnify the Depositary, any Depositary's Agent and any Registrar against, and
hold each of them harmless from, any loss, liability or expense (including the
costs and expenses of defending itself) which may arise out of (i) acts
performed or omitted in connection with this Deposit Agreement and the
Depositary Shares (a) by the Depositary, any Registrar or any of their
respective agents (including any Depositary's Agent), except for any liability
arising out of negligence, willful misconduct or bad faith on the respective
parts of any such person or persons, or (b) by the Company or any of its
agents, or (ii) the offer, sale or registration of the Depositary Shares or the
Stock pursuant to the provisions hereof.  The obligations of the Company set
forth in this Section 5.06 shall survive any succession of any Depositary,
Registrar or Depositary's Agent.

        SECTION 5.07.  Charges and Expenses.  The Company shall pay all
transfer and other taxes and governmental charges arising solely from the
existence of the depositary arrangements.  The Company shall pay all charges of
the Depositary in connection with the initial deposit of the Stock and the
initial issuance of the Receipts, any redemption of the Stock at the option of
the Company and any withdrawals of Stock by holders of Depositary Shares.  All
other transfer and other taxes and governmental charges shall be at the expense
of holders of Depositary Shares.  If, at the request of a holder of a
Depositary Share, the Depositary incurs charges or expenses for which it is not
otherwise liable hereunder, such holder will be liable for such charges and
expenses.  All other charges and expenses of the Depositary, any Depositary's
Agent hereunder and any Registrar (including, in each case, fees and expenses
of counsel) incident to the performance of their respective obligations
hereunder will be paid upon consultation and agreement between the Depositary
and the Company as to the amount and nature of such charges and expenses.  The
Depositary shall present its statement for charges and expenses to the Company
once every three months or at such other intervals as the Company and the
Depositary may agree.

                                   ARTICLE VI

                           AMENDMENT AND TERMINATION

        SECTION 6.01.  Amendment.  The form of the Receipts and any provisions
of this Deposit Agreement may at any time and from time to time be amended by
agreement between the Company and the Depositary in any respect which they may
deem necessary or desirable;provided, however, that no such amendment which
shall materially and adversely alter the rights of the existing holders of
Depositary Shares shall be effective unless such amendment shall have been
approved by the holders of at least a majority of the Depositary Shares then
outstanding.  Every holder of an outstanding Depositary Share at the time any
such amendment becomes effective shall be deemed, by continuing to hold such
Depositary Share, to consent and agree to such amendment and to be bound by
this Deposit Agreement as amended thereby.  In no event shall any amendment
impair the right, subject to the provisions of Sections 2.03, 2.06 and Article
III, of any owner of any Depositary Shares to surrender the Receipt evidencing
such Depositary Shares with instructions to the Depositary to deliver to the
holder the Stock and all money and other property, if any, represented thereby,
except in order to comply with mandatory provisions of applicable law.

        SECTION 6.02.  Termination.  This Deposit Agreement may be terminated
by the Company or the Depositary only after (a)(i) all outstanding Depositary
Shares shall have been redeemed and any accumulated and unpaid dividends on the
Stock represented by the Depositary Shares, together with all other moneys and
property, if any, to which holders of the related Receipts are entitled under
the terms of such Receipts or this Deposit Agreement, have been paid or
distributed as provided in this Deposit Agreement or provision therefor has
been duly made pursuant to Section 2.03 or (ii) there shall have been made a
final distribution in respect of the Stock in connection with any liquidation,
dissolution or winding up of the Company and such distribution shall have been
distributed to the holders of Receipts pursuant to Section 4.01 or 4.02, as
applicable and (b) reasonable notice has been given to any holders of Receipts.

        If any Receipts shall remain outstanding after the date of termination
of this Deposit Agreement, the Depositary thereafter shall discontinue the
transfer of Receipts, shall suspend the distribution of dividends to the
