composite currencies, including the European Currency Unit), plus an
indeterminate number of shares as may be issued upon conversion of Debt
Securities or Preferred Stock for which no separate consideration will be
received.
/2/  The proposed maximum offering price per unit will be determined from time 
to time by the Registrant in connection with the issuance by the Registrant of
the securities registered hereunder.
/3/  Estimated solely for the purpose of computing the registration fee.
/4/  Exclusive of accrued interest, if any.

Preferred Stock or Common Stock that are issued upon conversion of or in
exchange for Debt Securities or Preferred Stock or (ii) Common Stock to be
issued upon exercise of related Warrants to purchase Common Stock.
/7/  Each share of Common Stock registered hereby includes one Right to purchase
additional of the Company's securities, which Right will not be evidenced
separately from the Common Stock prior to the occurrence of certain events.
These Rights will be triggered by a future acquisition of a certain percentage
of the Company's outstanding Common Stock by a stockholder or group of
stockholders.



                             ----------------------
          The Registrant hereby amends this registration statement on such date

   Debt Securities, Preferred Stock, Common Stock, and Warrants to Purchase 
                                 Common Stock

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

First Security Corporation (the "Company") may from time to time issue and offer
(a) its notes, debentures or other unsecured evidences of indebtedness in one or
more series ("Debt Securities"), which may be either senior ("Senior Debt
Securities") or subordinated ("Subordinated Debt Securities") in priority of
payment; (b) shares of one or more series of its Preferred Stock ("Preferred
Stock"); (c) shares of its Common Stock (par value $1.25) ("Common Stock"); and
(d) warrants to acquire Common Stock ("Common Stock Warrants") either directly
or in conversion or exchange for other securities.  (When appropriate, all of
the foregoing types of securities are referred to herein as "the Securities".)

The Securities are not savings accounts, deposits or other obligations of any
bank or nonbank subsidiary of the Company and are not insured by the Federal
Deposit Insurance Corporation, Bank Insurance Fund or any other government
agency.

The Senior Debt Securities will rank equally with all other unsubordinated and
unsecured indebtedness of the Company.  The Subordinated Debt Securities will be
subordinated to all of the Company's existing and future Senior Debt, as
defined.  See "Description of Debt Securities."

The Company may offer the Securities up to an aggregate initial offering price
not to exceed US$300,000,000 or, as to Debt Securities, its equivalent based on
the applicable exchange rate at the time of offering in such foreign currencies
or units of two or more currencies thereof as may be designated by the Company
at the time of such an offering.  Debt Securities or Preferred Stock of each
series will be offered on terms determined at the time of sale.  When any of the
Securities is offered, a supplement to this Prospectus (the "Prospectus
Supplement") setting forth certain terms of the offered Securities will be
delivered together with this Prospectus.  With regard to Debt Securities or
Preferred Stock in respect of which this Prospectus is being delivered, the
Prospectus Supplement will set forth, if applicable, the specific designation,
aggregate principal amount or redemption value, rate (or method of calculation)
or dividend and time of payment of any interest or dividend, maturity, initial
public offering price, place or places of payment of interest or dividends,
redemption terms and other terms of such Securities.

The Securities may be sold to underwriters for public offering pursuant to the
terms of offering fixed at the time of sale.  Such underwriters may include J.P.
Morgan Securities Inc. and CS First Boston, or may be a group of underwriters
represented by such firms.  In addition, any of the Securities may be sold to
the public by the Company directly or through agents or dealers.  J.P. Morgan
Securities Inc. and CS First Boston may also act as agent.  If any underwriters
or agents are involved in the sale of any Securities, their names and any
applicable fee, commission, purchase price or discount arrangements with them
will be set forth, or will be calculated from the information set forth, in a
Prospectus Supplement.  See "Plan of Distribution."

     This Prospectus may not be used to consummate sales of any securities
                 unless accompanied by a Prospectus Supplement.

                           FIRST SECURITY CORPORATION

General

          The Company is a Delaware incorporated multi-bank holding company
headquartered in Salt Lake City, Utah.  At December 31, 1993, the Company and
its subsidiaries had total consolidated assets and shareholders' equity of
$10.21 billion and $836 million, respectively.

          The principal banking subsidiaries of the Company are First Security
Bank of Utah N.A. ("First Security Utah"), First Security Bank of Idaho, N.A.
("First Security Idaho"), and First Security Bank of New Mexico, N.A. ("First
Security New Mexico"), all of which are commercial banking institutions
providing a broad range of banking, fiduciary, financial and other services.
The Company also operates banks in Wyoming ("First Security Wyoming"), Oregon
("First Security Oregon") and Nevada ("First Security Nevada") (all of the
Company's banking subsidiaries will be referred to hereafter as "the Banks").
Nonbank subsidiaries owned by the Company include a leasing company, a mortgage
company, a securities broker-dealer, an investment adviser, an insurance agency,
a credit life insurance company and a management and services company.

          In addition to its equity investments in its subsidiaries, the
Company directly or indirectly raises funds principally to finance the
operations of its nonbank subsidiaries.  A substantial portion of the Company's
cash flow is typically derived from dividends directly from its bank and nonbank
subsidiaries, and from interest on loans to the Company's nonbank subsidiaries.
Various statutory provisions limit the amount of dividends subsidiary Banks and
certain nonbank subsidiaries can pay to the Company without regulatory approval.
In addition, because any obligations issued by the Company hereunder will only
be obligations of the Company, not of any of its subsidiary Banks or nonbanking
operations, the holders of obligations issued by the Company hereunder will be
subordinated to certain prior claims by creditors of the Company's subsidiaries.
See "Supervision and Regulation."

          The Company maintains its executive offices at 79 South Main Street,
Salt Lake City, Utah  84111, telephone 801-246-6000.

Competition

          Based on deposits, at December 31, 1993, First Security Utah was the
largest bank in the State of Utah. Based on deposits, at December 31, 1993,
First Security Idaho was the second largest bank in the State of Idaho. In
Wyoming and Oregon, FSC's banks are smaller, more localized competitors. First
Security Oregon, at March 31, 1993, was the 12th largest bank in Oregon. First
Security Wyoming, at December 31, 1993, was the 18th largest bank in Wyoming.

          Of the Company's new subsidiaries, First Security New Mexico is the
second largest bank in the Albuquerque area and the third largest bank in New
Mexico.  First Security Nevada is a smaller bank located in the growing Clark
County (Las Vegas) market.

          The Company's banks compete with other banking organizations in the
states in which they operate on the basis of price, service and convenience.
Other types of financial institutions, such as savings banks, savings and loan
associations and credit unions offer a wide range of deposit and loan services
(including commercial loans) and, in some instances, fiduciary services.  The
Company's banks also compete with brokerage firms, insurance companies and
mutual funds which provide investment products and, in many cases, the
substantial equivalent of checking accounts, credit cards and similar products
traditionally provided by commercial banks.  Major retailers compete with the

                                       4
<PAGE>
 
Company's lending operations by offering credit cards and retail installment
contracts.  It is anticipated that competition from nonbank organizations will
continue to grow.


Ratio of Earnings to Fixed Charges and Ratio of Earnings to Combined Fixed
Charges and Preferred Stock Dividends

          For the fiscal years ended December 31, 1993, 1992, 1991, 1990 and
1989 the Company's consolidated ratios of earnings to combined fixed charges and
preferred stock dividends, and its ratio of earnings to fixed charges,
excluding interest on deposits were 4.62, 2.28, 1.33, 1.72, respectively; and
such ratios including interest on deposits were 1.71, 1.54, 1.23, 1.08, 1.19,
respectively.  For purposes of computing the consolidated ratio of earnings to
combined fixed charges and preferred stock dividends, earnings represent net
income plus income taxes and fixed charges.  Fixed charges, excluding interest
on deposits, include interest expense (except interest paid on deposits),
capitalized interest, an amount equal to the pretax earnings required to meet
applicable preferred stock dividend requirements and the interest factor
included in rents.  Fixed charges, including interest on deposits, include all
interest expense, capitalized interest, an amount equal to the pretax earnings
required to meet applicable preferred stock dividend requirements and the
interest factor included in rents.


Supervision and Regulation

          References in this section to applicable statutes and regulations are
brief summaries only, and do not purport to be complete.  The reader should
consult such statutes and regulations themselves for a full understanding of the
details of their operation.

Bank Holding Company Regulation
- -------------------------------

          The Company is a bank holding company registered under Bank Holding
Company of 1956 (the "BHC Act"), and is subject to supervision and regulation by
the Federal Reserve Board.  Federal laws subject bank holding companies to
particular restrictions on the types of activities in which they may engage, and
to a range of supervisory requirements and activities, including regulatory
enforcement actions for violation of laws and policies.  In addition, Utah law
authorizes the state bank regulators to supervise and regulate under limited
circumstances a holding company controlling a Utah domiciled bank.

          - Activities "Closely Related" to Banking.  The BHC Act prohibits a
bank holding company, with certain limited exceptions, from acquiring direct or
indirect ownership or control of any voting shares of any company which is not a
bank or from engaging in any activities other than those of banking, managing or
controlling banks and certain other subsidiaries, or furnishing services to or
performing services for its subsidiaries.  One principal exception to these
prohibitions allows the acquisition of interests in companies whose activities
are found by the Federal Reserve Board to be so closely related to banking,
managing, or controlling banks as to be a proper incident thereto.  Such
activities include making or servicing loans, performing certain data processing
services, acting as an investment or financial advisor to certain investment
trusts and investment companies, and providing securities brokerage services.

          - Securities Activities.  The Federal Reserve Board has approved
applications by bank holding companies to engage, through nonbank subsidiaries,
in certain securities underwriting activities, provided that the affiliates
would not be "principally engaged" in such activities for purposes of Section 20
of the Glass-Steagall Act.  In very limited situations, holding companies have
been permitted to underwrite and deal in corporate debt and equity securities
through such subsidiaries.

                                       5
<PAGE>
 
          - Safe and Sound Banking Practices.  Bank holding companies are not
permitted to engage in unsafe and unsound banking practices. The Federal Reserve
Board may order a bank holding company to terminate an activity or control of a
nonbank subsidiary if such activity or control constitutes a significant risk to
the financial safety, soundness or stability of a subsidiary bank and is
inconsistent with sound banking principles.

          The Financial Institutions Reform, Recovery, and Enforcement Act of
1989 ("FIRREA") expanded the Federal Reserve Board's authority to prohibit
activities of bank holding companies and their nonbanking subsidiaries which
represent unsafe and unsound banking practices or which constitute violations of
laws or regulations.  Notably, FIRREA increased the amount of monetary penalties
which the Federal Reserve Board can assess for such practices or violations to
as high as $1 million per day.  FIRREA also expanded the scope of individuals
and entities against which such penalties may be assessed.

          - Anti-Tying Restrictions.  Bank holding companies and their bank and
nonbank affiliates are prohibited from tying the provision of certain services,
such as extensions of credit, to other services offered by a holding company or
its affiliates.

          - Annual Reporting; Examinations.  The Company is required to file an
annual report with the Federal Reserve Board and such additional information as
the Federal Reserve Board may require pursuant to the BHC Act.  The Federal
Reserve Board may examine a bank holding company or any of its subsidiaries, and
charge the company for the cost of such an examination.

          - Capital Adequacy Requirements.  The Federal Reserve Board monitors
the capital adequacy of bank holding companies.  The Federal Reserve Board uses
a combination of risk-based guidelines and leverage ratios to evaluate capital
adequacy.  The Federal Reserve Board has adopted a system based upon the Basle
Accord, an international standard for risk-based capital guidelines, to evaluate
the capital adequacy of bank holding companies.  Under the risk-based capital
guidelines, different categories of assets are assigned different risk weights,
based generally on the perceived credit risk of the asset.  These risk weights
are multiplied by corresponding asset balances to determine a "risk-weighted"
asset base.  Certain off-balance sheet items, which previously were not
expressly considered in capital adequacy computations, are added to the risk-
weighted asset base by converting them to a balance sheet equivalent and
assigning to them the appropriate risk weight.  Total capital is defined as the
sum of "Tier 1" and "Tier 2" capital elements, with "Tier 2" being limited to
100% of "Tier 1."  For bank holding companies, "Tier 1" capital includes, with
certain restrictions, common stockholders' equity, retained earnings, non-
cumulative perpetual preferred stock and minority interests in consolidated
subsidiaries less certain intangibles.  "Tier 2" capital includes, with certain
limitations, certain forms of non-qualifying perpetual preferred stock, maturing
capital instruments (such as qualifying convertible and/or subordinated debt),
the reserve for possible loan losses and specified levels of certain
intangibles.

          In addition to the risk-based capital guidelines, the Federal Reserve
Board has adopted the use of a leverage ratio as an additional tool to evaluate
the capital adequacy of banks and bank holding companies.  The leverage ratio is
a company's "Tier 1" capital divided by its adjusted total assets.  This
leverage ratio must be at least 3.0% for institutions with the Federal Reserve's
highest asset rating, called "CAMEL 1".  Institutions which are not CAMEL 1
rated are expected to maintain a leverage ratio of 4.0% to 5.0%, and
institutions planning acquisitions are expected to maintain higher ratios.

The following table sets forth the current regulatory requirements for capital
ratios of bank holding companies as compared with the Company's capital ratios
at December 31, 1993:

/(1)/  The leverage ratio is defined as the ratio of Tier 1 capital (using final
1992 risk-based capital guidelines to define Tier 1 capital) to average assets,
net of goodwill.  Federal Reserve Board Guidelines provide that all bank holding
companies (other than those that meet certain criteria) maintain a minimum
leverage ratio of 3%, plus an additional cushion of 100 to 200 basis points.
The guidelines also state that banking organizations 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.

/(2)/  Shareholders' equity less goodwill (Tier 1 capital) divided by risk-
weighted assets.

/(3)/  Tier 1 capital plus reserve for possible loan losses (limited to 1.25% of
total risk-weighted assets) plus qualified subordinated and convertible debt
(Tier 2 capital) divided by risk-weighted assets.


          Bank regulators continue to indicate their desire to raise capital
requirements applicable to banking organizations beyond their current levels.
Management cannot predict whether these capital requirements will change or
whether they will materially affect the Company's financial position or
operating ability.

          - Imposition of Liability for Undercapitalized Subsidiaries.  The
Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA")
requires each federal banking agency to revise its capital standards to reflect
the risk-weighting discussed above.  The new law also requires each federal
banking agency to specify the levels at which an insured institution would be
considered "well capitalized," "adequately capitalized," "undercapitalized,"
"significantly undercapitalized" and "critically undercapitalized."  Under the
regulations adopted by the banking agencies, each of the Company's subsidiary
banks was "well capitalized" as of December 31, 1993.

          FDICIA requires bank regulators to take "prompt corrective action" to
resolve problems associated with insured depository institutions.  In the event
an institution becomes "undercapitalized," it must submit a capital restoration
plan.  If an institution becomes "significantly undercapitalized" or "critically
undercapitalized," additional and significant limitations are placed on the
institution.  The capital restoration plan of an undercapitalized institution
will not be accepted by the regulators unless each company "having control of"
the undercapitalized institution "guarantees" the subsidiary's compliance with
the capital restoration plan until it becomes "adequately capitalized."  The
Company controls each of its subsidiaries for purposes of this statute and
therefore is required to ensure that each subsidiary remains adequately
capitalized.

          The "prompt corrective action" provisions of FDICIA reflect the same
concerns which gave rise to a position adopted by the Federal Reserve Board
known as the "source of strength doctrine," which is based on the Federal
Reserve Board's Regulation Y.  Regulation

                                       7
<PAGE>
 
Y directs bank holding companies to "serve as a source of financial and
managerial strength" to their subsidiary banks, and bars them from engaging in
unsafe and unsound practices.

          In addition, FIRREA also contains a "cross-guarantee" provision which
makes commonly controlled insured depository institutions liable to the FDIC for
any losses incurred in connection with the failure of an affiliated insured
depository institution.

          - Audit Reports.  Beginning January 1, 1994, FDICIA requires insured
depository institutions with $500 million or more in total assets, such as the
Company and each of its First Security Utah, First Security Idaho and First
Security New Mexico subsidiaries, to submit annual audit reports prepared by
independent auditors to federal and state regulators.  In most cases, the audit
report of the institution's holding company can be used to satisfy this
requirement.  The annual audit report shall include financial statements
prepared in accordance with generally accepted accounting principles, statements
concerning management's responsibility for the financial statements, internal
controls and compliance with legal requirements designated by the FDIC, and an
attestation by the auditor regarding the statements of management.  FDICIA
requires that independent audit committees be formed, consisting of outside
directors only.  The committees of institutions with assets of $3 billion or
more, such as the Company, must include members with experience in banking or
financial management, must have access to outside counsel, and must not include
representatives of large customers.  The Company's Board of Directors includes
an independent audit committee which complies with these requirements.

          - Acquisitions by Bank Holding Companies.  The BHC Act requires every
bank holding company to obtain the prior approval of the Federal Reserve Board
before it may acquire all or substantially all of the assets of any bank, or
ownership or control of any voting shares of any bank, if after such acquisition
it would own or control, directly or indirectly, more than 5% of the voting
shares of such bank.

          The Federal Reserve Board will only allow the acquisition by a bank
holding company of an interest in any bank located in another state if the state
in which the target bank is located expressly authorizes such acquisition.  Utah
banking laws permit, in certain circumstances, out-of-state bank holding
companies to acquire certain existing banks and bank holding companies in Utah.

          In addition, FDICIA has eased restrictions on cross-industry mergers
between commercial banks and savings institutions.  Members of the Bank
Insurance Fund ("BIF"), such as the Company, and the Savings Association
Insurance Fund are generally allowed to merge, assume each other's deposits, and
transfer assets in exchange for an assumption of deposit liabilities.

Subsidiary Bank Regulation
- --------------------------

          Three of the Company's bank subsidiaries are national banks, which are
subject to regulation and supervision by the Office of the Comptroller of the
Currency (the "Comptroller").  The other banks are each subject to regulation by
regulators in their respective states and the FDIC.  Bank regulations on both
the federal and state levels are broad in their scope and materially affect the
business of the Company and its banks.

                                       8
<PAGE>
 
          All of the Company's subsidiary banks are subject to the 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 and the types of services that may be
offered.  Various consumer laws and regulations also affect the operations of
the banks.  In addition to the impact of regulation, commercial banks are
affected significantly by actions of the Federal Reserve Board as it attempts to
control the money supply and credit availability.

          - Permissible Activities for State-Chartered Institutions/Equivalence
to National Bank Powers. FDICIA provides that, effective December 19, 1992, no
state bank or subsidiary thereof may engage as principal in any activity not
permitted for national banks, unless the institution complies with applicable
capital requirements and the FDIC determines that the activity poses no
significant risk to the insurance fund. In general, statutory restrictions on
the activities of banks are aimed at protecting the safety and soundness of
depository institutions. Many of the statutory restrictions limit the
participation of such institutions in the securities and insurance product
markets. Each of the state-chartered banking subsidiaries of the Company is in
compliance with the restrictions imposed by FDICIA.

          - Restrictions on Transactions With Affiliates. Section 23A of the
Federal Reserve Act imposes quantitative and qualitative limits on loan
transactions between a bank and its affiliates, and also requires certain levels
of collateral for such loans. It also limits the amount of advances to third
parties which are collateralized by the securities or obligations of the Company
or its subsidiaries. Section 23B of the Federal Reserve Act requires that
certain transactions between the Company's subsidiary banks and their affiliates
must be on terms at least as favorable to the Company or its subsidiaries as
those prevailing for comparable transactions with other nonaffiliated companies.
In the absence of such comparable transactions, any transaction between the
Company and its affiliates must be on terms and under circumstances, including
credit standards, that in good faith would be offered to or would apply to
nonaffiliated companies. The Company is currently in material compliance with
the requirements of Sections 23A and 23B.

          - Restrictions on Subsidiary Bank Dividends. The Federal Reserve
Board, the Comptroller and the FDIC have each issued policy statements to the
effect that bank holding companies and member banks, national banks and state
banks should generally only pay dividends out of current operating earnings. The
prior approval of the Comptroller is required if the total of all dividends
declared by the board of directors of a national bank, such as First Security
Utah, First Security Idaho and First Security New Mexico, in any calendar year
will exceed the aggregate of the bank's net profits (as defined by regulatory
authorities) for that year and its retained net profits for the preceding two
years. Similar restrictions govern the other banking subsidiaries of the
Company. In addition, national banks can pay dividends only to the extent that
retained net profits exceed "bad debts", which are generally defined to include
the principal amount of loans that are in arrears as to interest by nine months
or more and that are not secured and that are not in the process of collection.
As of December 31, 1993, the Company's banks could

                                       9
<PAGE>
 
have declared additional dividends to the Company of approximately $119.97
million without regulatory approval or restriction. Federal banking regulators
also may prohibit federally insured banks from paying dividends if the payment
of such dividend would leave the bank "undercapitalized" as defined in FDICIA
and the implementing regulations, or the payment of dividends would, in light of
the financial condition of such bank, constitute an unsafe or unsound practice.
Applicable Nevada, Wyoming and Oregon law place similar restrictions on the
payment of dividends by the Company's banks organized under the laws of those
states.

          - Examinations. The FDIC periodically examines and evaluates insured
banks. Based upon such an evaluation, the FDIC may revalue the assets of an
insured institution and require that it establish specific reserves to
compensate for the difference between the FDIC-determined value and the book
value of such assets. FDICIA requires that these on-site examinations be
conducted every 12 months, except that certain well capitalized banks may be
examined every 18 months. The rules and regulations of the Comptroller, which
regulates the Company's national banks, and the various state banking
authorities regulating the Company's state-chartered banks also provide for
periodic examinations by those agencies.

          - Standards for Safety and Soundness. As part of FDICIA's efforts to
promote the safety and soundness of depository institutions and their holding
companies, the Federal Reserve Board issued for public comment on April 19,
1993, proposed regulations on standards of safety and soundness which specify
operational and management standards (addressing internal controls, loan
documentation, credit underwriting and interest rate risk), asset quality and
earnings. The impact of these regulations cannot be determined until final
regulations are issued.

          - Deposit Insurance Assessments. FDIC-insured depository institutions
that are members of the BIF must pay insurance premiums at rates between 23 and
31 basis points on insured deposits depending on the bank's capital category and
bank regulators' supervisory category. Institutions assigned to higher-risk
categories--that is, institutions that pose a greater risk of loss to their
respective deposit insurance funds--would pay assessments at higher rates than
would institutions that pose a lower risk. The FDIC can impose special
assessments on member institutions, such as each of the Company's Bank
subsidiaries, to cover the cost of borrowings from the U.S. Treasury, the
Federal Financing Bank, and BIF member banks. The semiannual assessment is based
on: (1) the probability of a loss to the BIF; (2) the potential magnitude of the
loss; and (3) the revenue and reserve needs of the fund.

          - FIRREA's Impact. FIRREA's primary purpose was to restructure the
statutory and regulatory framework applicable to savings associations, and
establish a mechanism for resolving insolvent thrift institution cases. Certain
provisions of FIRREA, however, affect the bank subsidiaries of holding
companies, including the Company. Among the most significant of these provisions
are those which: (1) clarify the powers and duties of the FDIC as receiver or
conservator of a bank; (2) enhance the enforcement powers of the federal banking
regulators;

                                      10
<PAGE>
 
          (3) establish new reporting requirements under the Home Mortgage
Disclosure Act designed to prevent discriminatory lending practices; (4) require
the federal banking agencies to make public a rating of a bank's performance
under the Community Reinvestment Act; and (5) prohibit banks from entering into
contracts with persons providing goods, products or services if the performance
of such contracts would adversely affect the bank's safety and soundness.
FIRREA's primary impact on commercial banks has been to increase the enforcement
authority of federal regulators and to expand the scope of potential targets of
enforcement actions.

          - Expanding Enforcement Authority.  One of the major additional 
burdens imposed on the banking industry by FDICIA is the increased ability of
banking regulators to monitor the activities of banks and their holding
companies. In addition, the Federal Reserve Board, Comptroller and FDIC are
given extensive authority to police unsafe or unsound practices and violations
of applicable laws and regulations by depository institutions and their holding
companies. For example, the FDIC may terminate the deposit insurance of any
institution which it determines has engaged in an unsafe or unsound practice.
The agencies can also assess civil money penalties of up to $1 million per day,
issue cease and desist or removal orders, seek injunctions, and publicly
disclose such actions. FDICIA, FIRREA and other laws have expanded the agencies'
authority in recent years, and the agencies have not yet fully tested the limits
of their powers.

          - Current Regulatory Structure.  The laws and regulations affecting
banks and bank holding companies are under continual review.  For example,
recent federal legislative proposals include bills which would consolidate all
banking regulators into one or two regulatory agencies and others which would
permit interstate branching to various degrees.  The rules and the regulatory
agencies in this area have changed significantly over recent years, and there is
reason to expect that similar changes, including changes which may materially
affect the Company's operations, will continue in the future.


                                USE OF PROCEEDS

          Unless otherwise set forth in the Prospectus Supplement, the net
proceeds from the sale of the Securities will be applied to the Company's
general funds to be utilized for such corporate purposes as may be determined by
management, including payment of cash amounts due upon completion of
acquisitions, funding of investments in or extensions of credit to the Company's
subsidiaries, and repayment of borrowings.  Except as otherwise described in the
Prospectus Supplement, specific allocations of the proceeds to such purposes
will not have been made at the date of the Prospectus Supplement, although
management of the Company will have determined that funds should be raised at
that time in anticipation of future funding requirements.  The precise amounts
and timing of payments due upon completion of acquisitions, of investments in
and extensions of credit to the subsidiaries, and the repayment of borrowings
will depend upon funding requirements and the availability of other funds.
Pending such application, net proceeds may be temporarily invested or applied to
the reduction of short-term indebtedness.

                                 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 by a Prospectus Supplement and the extent, if any, to which such general
provisions may not apply thereto will be described in the Prospectus Supplement
relating to such Debt Securities.

          The Debt Securities may be Senior Debt Securities or Subordinated Debt
Securities (both including but not limited to Medium-Term Notes).  The Senior
Debt Securities will be issued under an Indenture, to be dated as of March 1,
1994 (the "Senior Indenture") between the Company and The First National Bank of
Chicago, as Trustee (together with its successor trustee, if any, the "Senior
Trustee"), and the Subordinated Debt Securities will be issued under an
Indenture, to be dated as of March 1, 1994 (the "Subordinated Indenture")
between the Company and The First National Bank of Chicago, as Trustee (together
with its successor trustee, if any, the "Subordinated Trustee"). The Senior
Indenture and the Subordinated Indenture are collectively referred to herein as
the "Indentures," copies of the forms of which are filed as exhibits to the
Registration Statement of which this Prospectus is a part. References to the
"Trustee" below shall mean the Senior Trustee or the Subordinated Trustee. The
following summaries of certain provisions of the Indenture 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. Wherever particular sections, articles or defined terms of the
Indentures are referred to, it is intended that such sections, articles or
defined terms shall be incorporated herein by reference. Section and article
references used herein are references to the Applicable Indenture. Capitalized
terms not otherwise defined herein shall have the meaning given them in the
Applicable Indenture.

General

          Neither Indenture limits the amount of Debt Securities which may be
issued thereunder, and Debt Securities of any series may be issued thereunder up
to the aggregate principal amount which may be authorized from time to time by
the Company.  Neither the Indentures nor the Debt Securities will limit or
otherwise restrict the amount of other indebtedness which may be incurred or the
other securities which may be issued by the Company or any of its Subsidiaries.
The Debt Securities will be unsecured direct obligations of the Company.

          Because the Company is a holding company, its rights and the rights of
its creditors, including the holders of the Debt Securities, to participate in
the assets of any Subsidiary upon the latter's liquidation or recapitalization
would be subject to the prior claims of such Subsidiary's creditors except to
the extent that the Company may itself be a creditor with claims against the
Subsidiary that are recognized by a court having jurisdiction over such claims.

          Unless otherwise indicated in the Prospectus Supplement, principal of
and any premium and interest on the Debt Securities will be payable, and the
transfer of the Debt Securities will be registrable, at the currently designated
office of the Trustee at One First

                                      12
<PAGE>
 
National Plaza, Chicago, Illinois 60670.  In addition, payment of interest on
Debt Securities may, at the option of the Company, be made by check mailed to
the address of the person entitled thereto as it appears on the Security
Register.  (Sections 301, 305 and 1002).  Acting in accordance with each
Indenture, the Company intends also to designate the principal office of First
Security Utah as an office where principal, premium, and interest may be paid
and the transfer of the Debt Securities may be registered.  (Sections 301, 305
and 1002)

          Unless otherwise indicated in the Prospectus Supplement, the Debt
Securities will be issued only in fully registered form, without coupons, in
denominations of $1,000 and any integral multiple thereof.  (Section 302)  No
service charge will be made for any registration of transfer or exchange of the
Debt Securities, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.
(Section 302)  The Indentures also provide that the Debt Securities of any
series, if so specified with respect to a particular series, may be issued in
permanent global form.  See "Global Debt Securities."

          Reference is made to the Prospectus Supplement for a description of
the following terms, where applicable, of each series of Debt Securities in
respect of which this Prospectus is being delivered: (1) the title of the Debt
Securities of the series; (2) any limit on the aggregate principal amount of the
Debt Securities of the series; (3) the date or dates on which the principal of
the Debt Securities of the series will be payable; (4) the rate or rates (which
may be fixed or variable) at which the Debt Securities of the series will bear
interest, if any, the date or dates from which such interest shall accrue, the
Interest Payment Dates on which such interest will be payable, and the Regular
Record Dates for such Interest Payment Dates; (5) the place or places where the
principal of, premium, if any, and interest on the Debt Securities of the series
shall be payable; (6) the period or periods within which, the price or prices at
which and the terms and conditions upon which the series of Debt Securities may
be redeemed, in whole or in part, at the option of the Company; (7) the
obligation, if any, of the Company to redeem or purchase the Debt Securities of
the series pursuant to any sinking fund or analogous provision or at the option
of the Holders thereof and the period or periods within which, the price or
prices at which and the terms and conditions upon which Debt Securities of the
series shall be redeemed or purchased, in whole or in part, pursuant to such
obligation; (8) the denomination or denominations in which such Debt Securities
are authorized to be issued; (9) the currency of payment of principal of,
premium, if any, and interest on the Debt Securities of the series; (10) any
index or formula used to determine the amount of payment of principal of,
premium, if any, and interest on the Debt Securities of the series; (11) if
other than the principal amount thereof, the portion of the principal amount of
Debt Securities of the series which shall be payable upon declaration of
acceleration of the Maturity thereof; (12) whether the Debt Securities of the
series shall be issued in whole or in part in the form of one or more Global
Securities and, if so, the Depositary for such Global Security or Securities;
(13) the portion of the principal amount of such Debt Securities which will be
payable upon declaration of acceleration of the Maturity thereof, if other than
the principal thereof; (14) any additional Events of Default or, in the case of
Subordinated Debt Securities, Default, solely with respect to the Debt
Securities; (15) whether the provisions of the applicable Indenture described
under "Defeasance and Covenant Defeasance" will be applicable to such Debt
Securities; (16) any additional restrictive covenants included solely for the
benefit of the Debt Securities; (17) if the Debt Securities are Subordinated
Debt Securities, whether the provisions in the Subordinated

                                      13
<PAGE>
 
Indenture described under "Subordination of Subordinated Debt Securities" or
other subordination provisions will be applicable to such Subordinated Debt
Securities; and (18) any other terms of the series of Debt Securities not
inconsistent with the provisions of the Applicable Indenture.

          The Debt Securities may be issued as Original Issue Discount Debt
Securities, to be offered and sold at a discount below their stated principal
amount.  Any such Original Issue Discount Debt Securities will be described in
the Prospectus Supplement related thereto, which description will include a
discussion of the material federal income tax consequences and other special
considerations applicable to any such Original Issue Discount Debt Securities.
An "Original Issue Discount Security" is generally a Debt 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 upon the
occurrence of an Event of Default and the continuation thereof.

Conversion and Exchange

          The terms, if any, on which Debt Securities of any series are
convertible into or exchangeable for shares of Common Stock, Preferred Stock or
Warrants will be set forth in the Prospectus Supplement related thereto.  Such
terms may include provisions for conversion or exchange, either mandatory, at
the option of the holder, or at the option of the Company, in which the number
of shares of Common Stock, Preferred Stock or Warrants to be received by the
holders of Debt Securities would be calculated according to the market price of
Common Stock, Preferred Stock or Warrants as of a time stated in the Prospectus
Supplement.

Subordination of 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 (as defined in the Subordinated Indenture).  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 (as defined in the Subordinated
Indenture and defined below).  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 Company, 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.  If upon any such payment or
distribution of assets to creditors, there remain, after giving effect to such
subordination provisions in favor of the holders of Senior Indebtedness, any
amounts of cash, property or securities available for payment or distribution in
respect of Subordinated Debt Securities (as defined in the Subordinated
Indenture and defined below, "Excess Proceeds") and if, at such time, any
Entitled Persons 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

                                      14
<PAGE>
 
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.  In the event of the acceleration of the maturity of any 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 principal of or interest on the Subordinated Debt Securities or on
account of the purchase or acquisition of Subordinated Debt Securities may be
made if there shall have occurred and be continuing a default in any payment
with respect to Senior Indebtedness, or if any judicial proceeding shall be
pending with respect to any such default.  (Article Thirteen 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 Company who are not
holders of Senior Indebtedness or of the Subordinated Debt Securities may
recover less, ratably, than 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 of Other Financial Obligations, in the
event of insolvency, holders of Existing Subordinated Indebtedness (as defined
in the Subordinated Indenture and defined below) 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.

          Unless otherwise specified in the Prospectus Supplement relating to
the particular series of Subordinated Debt Securities offered thereby, Senior
Indebtedness is defined in the Subordinated Indenture as (a) the principal of
(and premium, if any), and interest on all indebtedness of the Company for money
borrowed, whether outstanding on the date of execution of the Subordinated
Indenture or thereafter created, assumed or incurred, except (i) such
indebtedness as is by its terms expressly stated to be junior in right of
payment to the Subordinated Debt Securities and (ii) such indebtedness as is by
its terms expressly stated to rank pari passu with the Subordinated Debt
                                   ---- -----                           
Securities and (b) any deferrals, renewals or extensions of any such Senior
Indebtedness; provided, however, that Senior Indebtedness shall not include
              --------  -------                                            
Existing Subordinated Indebtedness.  (Section 101 of the Subordinated Indenture)
The term "indebtedness for money borrowed" when used with respect to the Company
is defined to mean any obligation of, or any obligation guaranteed by, the
Company for the repayment of borrowed money, whether or not evidenced by bonds,
debentures, notes or other written instruments, and any deferred obligation of,
or any such obligation guaranteed by, the Company for the payment of the
purchase price of property or assets.  (Section 101 of the Subordinated
Indenture)

          Unless otherwise specified in the Prospectus Supplement relating to
the particular series of Subordinated Debt Securities offered thereby, Existing
Subordinated Indebtedness means the Company's 7.50% Subordinated Notes due 2002
issued under an Indenture, dated as of August 1, 1991, between the Company and
Norwest Bank Minnesota, N.A., as trustee.

          Unless otherwise specified in the Prospectus Supplement relating to
the particular series of Subordinated Debt Securities offered thereby, Other
Financial Obligations

                                      15
<PAGE>
 
means (a) obligations of the Company under direct credit substitutes, (b)
obligations of, or any such obligation directly or indirectly guaranteed by, the
Company for purchased money or funds, (c) any deferred obligation of, or any
such obligation directly or indirectly guaranteed by, the Company for the
payment of the purchase price of property or assets, (d) any obligation of, or
any such obligation directly or indirectly guaranteed by, the Company for the
payment of rent or other amounts under a lease of property or assets which
obligation is required to be classified and accounted for as a capitalized lease
on the balance sheet of the Company under generally accepted accounting
principles, and (e) all obligations of the Company to make payment pursuant to
the terms of financial instruments, such as (i) securities contracts and
foreign currency exchange contracts, (ii) 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 (iii) in the case of both (i) and (ii)
above, similar financial instruments, other than (A) obligations on account of
Senior Indebtedness and (B) obligations on account of indebtedness for money
borrowed ranking pari passu with or subordinate to the Subordinated Debt
                 ---- -----                                             
Securities.  Unless otherwise specified in the Prospectus Supplement relating to
the particular series of Subordinated Debt offered thereby, Entitled Persons
means any person who is entitled to payment pursuant to the terms of Other
Financial Obligations.  (Section 101 of the Subordinated Indenture)

          Indebtedness of the Company senior to the Subordinated Debt
Securities, at March 1, 1994, totalled approximately $319 million ($244 million
if the currently outstanding subordinated debt securities are ranked pari passu
                                                                     ----------
with the new Subordinated Debt Securities).

          The Company'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 to the obligations of the Holders of
Subordinated Debt Securities to pay over any Excess Proceeds to Entitled Persons
in respect of Other Financial Obligations as provided in the Subordinated
Indenture.

          The Subordinated Indenture does not limit or prohibit the incurrence
of additional Senior Indebtedness, which may include indebtedness that is senior
to the Subordinated Debt Securities, but subordinate to other obligations of the
Company, including obligations of the Company in respect of Other Financial
Obligations.  The Senior Debt Securities, when issued, will constitute Senior
Indebtedness.

          The Prospectus Supplement may further describe the provisions, if any,
applicable to the subordination of the Subordinated Debt Securities of a
particular series.

Certain Covenants in the Senior Indenture

        Restrictions on Certain Dispositions of Major Constituent Banks.  The
        ---------------------------------------------------------------      
Senior Indenture provides that, except as described below under "Consolidation,
Merger and Sale of Assets", the Company will not (a) sell, assign, transfer, or
otherwise dispose of any shares of, or securities convertible into, or options,
warrants or rights to subscribe for or purchase shares of, Voting Stock of a
Major Constituent Bank (as defined below) (or a Subsidiary

                                      16
<PAGE>
 
owning Voting Stock of a Major Constituent Bank) or permit a  Major Constituent
Bank (or a Subsidiary owning Voting Stock of a Major Constituent Bank) to issue
any shares of, or securities convertible into or options, warrants or rights to
subscribe for or purchase shares of such Voting Stock, if, in each case, after
giving effect to any such transaction and to the issuance of the maximum number
of shares of Voting Stock of such Major Constituent Bank (or Subsidiary)
issuable upon the exercise of all such convertible securities, options, warrants
or rights, the Major Constituent Bank would cease to be a Controlled Subsidiary,
or (b) permit a Major Constituent Bank (or a Subsidiary owning Voting Stock of a
Major Constituent Bank) to (i) merge or consolidate with or into any other
corporation, unless the surviving corporation is, or upon consummation of the
merger or consolidation will become, a Controlled Subsidiary; or (ii) lease,
sell or transfer all or substantially all of its properties and assets to any
Person, except to a Controlled Subsidiary or a Person that, upon such lease,
sale or transfer, will become a Controlled Subsidiary.  The Senior Indenture,
however, provides that any such sale or other disposition of securities, any
such merger or consolidation or any such lease, sale or transfer of properties
and assets will not be prohibited (i) if required by any law or any rule,
regulation or order of any governmental agency or authority, (ii) if required as
a condition imposed by any law or rule, regulation or order of any governmental
agency or authority to the acquisition by the Company, directly or indirectly,
of any Person, provided that, after giving effect to such other prohibited
transaction and such acquisition, (A) such Person will be a Controlled
Subsidiary and (B) the Consolidated Banking Assets (as defined below) of the
Company will be at least equal to the Consolidated Banking Assets of the Company
prior thereto, or (iii) if the proceeds from such otherwise prohibited
transaction are within 180 days after such transaction, or such longer period of
time as may be necessary to obtain regulatory approval in connection therewith,
invested by the Company, pursuant to an understanding or agreement in principle
reached at the time of such otherwise prohibited transaction, in one or more
Controlled Subsidiaries (including any Person which upon such investment becomes
a Controlled Subsidiary) engaged in the banking business or any other business
then legally permissible for bank holding companies.  (Section 1008)

        "Major Constituent Bank" means (i) First Security Utah, First Security
Idaho and First Security New Mexico or (ii) any Subsidiary Bank the Consolidated
Banking Assets of which constitute 20% or more of the aggregate Consolidated
Banking Assets of all Subsidiary Banks.  As of December 31, 1993, First Security
Utah, First Security Idaho and First Security New Mexico were the only Major
Constituent Banks.  "Controlled Subsidiary" means any Subsidiary more than 80%
of the outstanding shares of the Voting Stock of which is at the time owned
directly or indirectly by the Company or by one or more Controlled Subsidiaries
or by the Company and one or more Controlled Subsidiaries.  "Consolidated
Banking Assets" of a Subsidiary Bank means all assets owned directly or
indirectly by such Subsidiary Bank and reflected on the Company's consolidated
balance sheet prepared in accordance with generally accepted accounting
principles.  (Section 101)

        Restrictions on Liens on Voting Stock of Major Constituent Banks.  The
        ----------------------------------------------------------------      
Senior Indenture provides that the Company will not create, assume, incur or
suffer to be created, assumed or incurred or to exist any pledge, encumbrance or
lien, as security for indebtedness for borrowed money, upon any shares of, or
securities  convertible into or options, warrants or rights to subscribe for or
purchase shares of, Voting Stock of a Major Constituent Bank now or hereafter
owned by the Company, directly or indirectly, without making effective provision
whereby any Debt Securities shall be equally and ratably secured with any and
all

                                      17
<PAGE>
 
such indebtedness if, treating such pledge, encumbrance or lien as a transfer of
the shares of, or securities convertible into or options, warrants, or rights to
subscribe for or purchase shares of, Voting Stock subject thereto to the secured
party and after giving effect to the issuance of the maximum number of shares of
Voting Stock of such Major Constituent Bank issuable upon the exercise of all
such convertible securities, options, warrants or rights, the Major Constituent
Bank would not continue to be a Controlled Subsidiary.  (Section 1009)

        Neither the Senior Indenture nor the Subordinated Indenture contain any
restriction on the Company's ability to enter into a highly leveraged
transaction or any provision affording any special protection to Holders in the
event that the Company engages in a highly leveraged transaction.

Consolidation, Merger, and Sale of Assets

        The Indenture provides that the Company, without the consent of the
Holders of any of the Outstanding Debt Securities, may consolidate with or merge
into, or convey, transfer, or lease its properties and assets substantially as
an entirety to, any Person, provided that (a) the successor is a Person
organized under the laws of any domestic jurisdiction and assumes the Company's
obligations on the Debt Securities and under the Indenture, (b) after giving
effect to the transaction there exists no Event of Default or, in the case of
the Subordinated Indenture, Default, and no event which, after notice or lapse
of time would become an Event of Default or, in the case of the Subordinated
Indenture, Default, shall have occurred and be continuing, and (c) certain other
conditions are met.  (Section 801)

Global Debt Securities

        If any Debt Securities of a series are to be issued in permanent global
form, the Prospectus Supplement relating thereto will describe the
circumstances, if any, under which beneficial owners of interests in any such
permanent global Debt Security may exchange such interests for certificated Debt
Securities of such series and of like tenor and principal amount in any
authorized form and denomination.  Principal of and any premium and interest on
a permanent global Debt Security will be payable in the manner described in the
Prospectus Supplement relating thereto.  (Section 205).

Defeasance and Covenant Defeasance

        The Indentures provide under Article 13 (for the Senior Indenture) and
Article 14 (for the Subordinated Indenture), if such provision is made
applicable to the particular Debt Securities of any series pursuant to Section
301 of the Applicable Indenture (which will be indicated in the Prospectus
Supplement applicable thereto), that the Company may elect either (A) to defease
and be discharged from any and all obligations with respect to such Debt
Securities then outstanding (including, in the case of Subordinated Debt
Securities, the provisions described under "Subordination of Subordinated Debt
Securities" and except for the obligations to register the transfer or exchange
of such Debt Securities, to replace temporary or mutilated, destroyed, lost or
stolen Debt Securities, to maintain an office or agency in respect of the Debt
Securities and to hold moneys for payment in trust) ("defeasance") or (B) to be
released from its obligations with respect to such Debt Securities then
outstanding under Sections 1006 through Section 1009 of the Senior Indenture and

                                      18
<PAGE>
 
Sections 1006 and 1007 of the Subordinated Indenture (and any other sections
applicable to such Debt Securities that are determined pursuant to Section 301
to be subject to covenant defeasance), the occurrence of an event of default
specified in, in the case of Senior Debt Securities, Section 501(4) of the
Senior Indenture, and in the case of Subordinated Debt Securities, Section
503(C) of the Subordinated Indenture (with respect to Sections 1006 through
Section 1009 of the Senior Indenture and Sections 1006 and 1007 of the
Subordinated Indenture or any other section applicable to such Debt Securities
that are determined pursuant to Section 301 to be subject to covenant
defeasance), or, in the case of Senior Debt Securities, Section 501(5) of the
Senior Indenture, and in the case of Subordinated Debt Securities, Section
503(D) of the Subordinated Indenture (Section 1006 of the Indentures containing
the covenant to maintain properties, Section 1007 of the Indentures containing
the covenant to pay taxes and other claims, Section 1008 of the Senior Indenture
containing the restrictions described under "Restrictions on Certain
Dispositions of Major Constituent Banks", Section 1009 of the Senior Indenture
containing the restrictions described under "Restriction on Liens on Voting
Stock of Major Constituent Banks" and Sections 501(4) and 501(5) of the Senior
Indenture and Sections 503(C) and 503(D) of the Subordinated Indenture
containing the provisions described under "Defaults" relating to covenant
defaults and cross-defaults, respectively) and, in the case of Subordinated Debt
Securities, the provisions described under "Subordination of Subordinated Debt
Securities" ("covenant defeasance"), upon the deposit with the Senior Trustee or
Subordinated Trustee (or other qualifying trustee), in trust for such purpose,
of money, and/or U.S. Government Obligations which through the payment of
principal and interest in accordance with their terms will provide money, in an
amount sufficient, without reinvestment, to pay the principal of (and premium,
if any) and interest on such Debt Securities to maturity or redemption, as the
case may be, and any mandatory sinking fund or analogous payments thereon. As a
condition to defeasance or covenant defeasance, the Company must deliver to the
Senior Trustee or Subordinated Trustee an Opinion of Counsel (as specified in
the Applicable Indenture) to the effect that the Holders of such Debt Securities
will not recognize income, gain or loss for Federal income tax purposes as a
result of such defeasance or covenant defeasance and will be subject to Federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such defeasance or covenant defeasance had not
occurred. Such opinion, in the case of defeasance under clause (A) above, must
refer to and be based upon a ruling of the Internal Revenue Service issued to
the Company or published as a revenue ruling or upon a change in applicable
Federal income tax law, in any such case after the date of the Applicable
Indenture.

        Under current Federal income tax law, defeasance would likely be treated
as a taxable exchange of Debt Securities to be defeased for interests in the
defeasance trust.  As a consequence a holder would recognize gain or loss equal
to the difference between the holder's cost or other tax basis for such Debt
Securities and the value of the holder's proportionate interest in the
defeasance trust, and thereafter would be required to include in income a
proportionate share of the income, gain and loss of the defeasance trust.  Under
current Federal income tax law, covenant defeasance would ordinarily not be
treated as a taxable exchange of such Debt Securities.  Purchasers of such Debt
Securities should consult their own advisors with respect to the tax
consequences to them of such defeasance and covenant defeasance, including the
applicability and effect of tax laws other than the Federal income tax law.

                                      19
<PAGE>
 
        The Company may exercise its defeasance option with respect to such Debt
Securities notwithstanding its prior exercise of its covenant defeasance option.
If the Company exercises its defeasance option, payment of such Debt Securities
may not be accelerated because of an Event of Default.  If the Company exercises
its covenant defeasance option, payment of such Debt Securities may not be
accelerated by reference to the covenants noted under clause (B) above.
However, if such an acceleration were to occur, the realizable value at the
acceleration date of the money and U.S. Government Obligations in the defeasance
trust could be less than the principal and interest then due on such Debt
Securities, in that the required deposit in the defeasance trust is based upon
scheduled cash flows rather than market value, which will vary depending upon
interest rates and other factors.  (Article 13 and Article 14 of the Senior
Indenture and the Subordinated Indenture, respectively).

        The Prospectus Supplement may further describe the provisions, if any,
applicable to defeasance or covenant defeasance with respect to the Debt
Securities of a particular series.

Default

  The Senior Indenture
  --------------------


        The following are Events of Default under the Senior Indenture with
respect to Senior Debt Securities of any series:  (1) failure to pay principal
of or premium, if any, on any Debt Securities of that series when due; (2)
failure to pay any interest on any Senior Debt Securities of that series, when
due, continued for 30 days; (3) failure to deposit any sinking fund payment,
when due, in respect of any Senior Debt Securities of that series; (4) failure
to perform any other covenant of the Company in the Senior Indenture (other than
a covenant included in the Senior Indenture solely for the benefit of series of
Senior Debt Securities other than that series), continued for 60 days after
written notice as provided in the Senior Indenture; (5) failure to pay when due
the principal of or the acceleration of any indebtedness for borrowed money by
the Company or any Major Constituent Bank, in any individual instance or in the
aggregate in the principal amount in excess of $1,000,000, if such indebtedness
is not discharged or such acceleration is not annulled within 10  days after
written notice as provided in the Senior Indenture; (6) certain events in
bankruptcy, insolvency, or reorganization of the Company or any Major
Constituent Bank; and (7) any other Event of Default provided in any
supplemental indenture entered into with respect to Senior Debt Securities of a
particular series as described in the Prospectus Supplement.  (Section 501)

        If an Event of Default with respect to Senior Debt Securities of any
series shall occur and be continuing, either the Trustee or the Holders of at
least 25% in aggregate principal amount of the Outstanding Senior Debt
Securities of that series by notice as provided in the Indenture may declare the
principal amount to be due and payable immediately.  At any time after a
declaration of acceleration with respect to Senior Debt Securities of any series
has been made, but before a judgment or decree for payment of money has been
obtained by the Trustee, the Holders of a majority in aggregate principal amount
of outstanding Senior

                                      20
<PAGE>
 
Debt Securities of that series may, under certain circumstances, rescind and
annul such acceleration.  (Sections 502 and 503)

  The Subordinated Indenture
  --------------------------

        The Subordinated Indenture defines an Event of Default with respect to
any series of Subordinated Debt Securities as being certain events involving the
bankruptcy, insolvency or reorganization of the Company or any other Event of
Default provided with respect to Securities of any series.  (Section 501)  If
any Event of Default with respect to Subordinated Debt Securities of any series
at the time Outstanding occurs and is continuing, either the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Subordinated
Debt Securities of that series may declare the principal amount of all
Subordinated Debt Securities of that series to be due and payable immediately
(provided that no such declaration is required upon certain events of
bankruptcy, insolvency or reorganization), but upon certain conditions such
declaration may be annulled and past defaults (except, unless theretofore cured,
a default in payment of principal of (or premium, if any), or interest on the
Subordinated Debt Securities of that series and certain other specified
defaults) may be waived by the Holders of a majority in principal amount of the
Outstanding Subordinated Debt Securities of that series on behalf of the Holders
of all Subordinated Debt Securities of that series.  (Sections 502 and 513)

          The Subordinated Indenture does not provide for any right of
acceleration of the payment of principal of a series of Subordinated Debt
Securities upon a default in the payment of principal or interest or in the
performance of any covenant or agreement in the Subordinated Debt Securities of
the particular series or in the Subordinated Indenture.  The Subordinated
Indenture defines a Default with respect to Subordinated Debt Securities of any
series as any one of the following events:  (1) an Event of Default; (2) failure
to pay any interest on any Subordinated Debt Securities of that series, when
due, continued for 30 days; (3) failure to pay principal of (or premium, if
any), on any Subordinated Debt Securities of that series when due; (4) failure
to deposit any sinking fund payment, when due, in respect of any Subordinated
Debt Securities of that series; (5) failure to perform any other covenant of the
Company in the Subordinated Indenture (other than a covenant included in the
Subordinated Indenture solely for the benefit of a series of Subordinated Debt
Securities other than that series) continued for 60 days after written notice as
provided in the Subordinated Indenture; (6) failure to pay when due the
principal of or the acceleration on any indebtedness for borrowed money by the
Company or a Major Constituent Bank, in any individual instance or in the
aggregate in the principal amount in excess of $3,000,000, if such indebtedness
is not discharged or such acceleration is not annulled within 10 days after
written notice as provided in the Subordinated Indenture;  and (7) any other
Default with respect to Subordinated Debt Securities of a particular series as
described in the Prospectus Supplement.  In case a Default shall occur and be
continuing, the Trustee may in its discretion proceed to protect and enforce its
rights and the rights of the Holders by appropriate judicial proceeding as the
Trustee deems most effectual.  (Section 503)

                                      21
<PAGE>
 
  The Senior and Subordinated Indentures
  --------------------------------------

        Reference is made to the Prospectus Supplement for the particular
provisions relating to acceleration of the Maturity of any portion of the
principal amount of a series of Debt Securities upon the occurrence of an Event
of Default and the continuation thereof.

        Each Indenture provides that, subject to the duty of the Trustee during
default to act with the required standard of care, the Trustee will be under no
obligation to exercise any of its rights or powers under the applicable
Indenture at the request or direction of any of the Holders unless such Holders
shall have offered to the Trustee reasonable indemnity.  (Section 603)  Subject
to such provisions for the indemnification of the Trustee, the Holders of a
majority in aggregate principal amount of the Outstanding Debt Securities of any
series will have the right to direct the time, method, and place of conducting
any proceeding for any remedy available to the Trustee, or exercising any trust
or power conferred on the Trustee, with respect to the Debt Securities of that
series.  (Series 512)

        Under each Indenture the Company is required to furnish annually to the
Trustee a statement as to the performance by the Company of certain of its
obligations under such Indenture and as to any default in such performance.
(Section 1004)

Modification of Indentures and Waiver of Conditions

        Modifications and amendments of each Indenture may be made by the
Company and the Trustee with the consent of the Holders of 66-2/3% in aggregate
principal amount of the Outstanding Debt Securities of each series affected by
such modification or amendment, provided, however, that no such modification or
                                --------  -------                              
amendment may, without the consent of the Holder of each Outstanding Debt
Security of each series affected thereby, (1) change the stated maturity date of
the principal of, or any installment of principal of or interest on, any Debt
Securities; (2) reduce the principal amount of, the rate of interest on or any
premium payable upon the redemption of any Debt Securities; (3) reduce the
amount of the principal of any Original Issue Discount Security that would be
due and payable upon a declaration of acceleration of the Maturity thereof; (4)
change any Place of Payment where, or the coin or currency in which, payment of
principal of, or any premium or interest on, any Debt Securities may be made;
(5) impair the right to institute suit for the enforcement of any payment on or
with respect to any Debt Securities; or (6) in the case of the Subordinated
Indenture, modify the provisions thereof with respect to the subordination of
the Subordinated Debt Securities in a manner adverse to the Holders thereof; or
(7) reduce the percentage in principal amount of Outstanding Debt Securities of
any series, the consent of whose Holders is required for modification or
amendment of the applicable Indenture or for waiver of compliance with certain
provisions of the applicable Indenture or for waiver of certain defaults.
(Section 902)

        Each Indenture provides that the Holders of 66-2/3% in aggregate
principal amount of the Outstanding Debt Securities of any series may, on behalf
of all Holders of Debt Securities of that series, waive, insofar as that series
is concerned, compliance by the Company with certain restrictive provisions of
the applicable Indenture with respect to the Debt Securities of such series.
(Section 1010 of the Senior Indenture, Section 1008 of the Subordinated
Indenture)  The Holders of a majority in aggregate principal amount of the

                                      22
<PAGE>
 
Outstanding Debt Securities of any series may, on behalf of all Holders of Debt
Securities of that series, waive any past default under the applicable Indenture
with respect to the Debt Securities of such series except a default in the
payment of principal or any premium or interest with respect to the Debt
Securities of such series or in respect of a covenant or provision of the
applicable Indenture which cannot be modified or amended without the consent of
the Holders of each Outstanding Debt Security of such series.  (Section 513)

Regarding the Trustee

        The First National Bank of Chicago is the Senior Trustee under the
Senior Indenture and the Subordinated Trustee under the Subordinated Indenture.
Certain of the Company's subsidiaries now, or in the future may, maintain
deposit accounts and/or other banking relationships with the Trustee.  



                         DESCRIPTION OF PREFERRED STOCK

        The following statements are brief summaries of the material provisions
relating to the Company's Preferred Stock and are qualified in their entirety by
the provisions of the Company's Certificate of Incorporation and Bylaws which
have been filed with the Commission.

        - Series A Preferred Stock.  The Company's Certificate of Incorporation
authorizes the issuance of 400,000 shares of preferred stock with no par value.
On December 31, 1993, there were 13,396 shares of $3.15 Cumulative Convertible
Preferred Stock, Series "A" (the "Series A Preferred Stock") outstanding.
Holders of Series A Preferred Stock have the right to receive semi-annual
dividends at the annual rate of $3.15 per share.  Such right is cumulative and
such dividends are payable before dividends may be paid on the Company's Common
Stock.  Each shares of Series A Preferred Stock is convertible into 12.15 shares
of the Company's Common Stock.  This conversion right is subject to adjustment
in certain events to protect against dilution of the conversion rights attached
to the Series A Preferred Stock.  In the event of a liquidation, dissolution or
winding up of the Company, the holders of Series A Preferred Stock are entitled
to receive cash value of $52.50 per share plus unpaid accumulated preferred
dividends before any distribution is made to holders of the Company's Common
Stock.  The Company may, at the option of the Board of Directors, redeem all or
any part of the outstanding Series A Preferred Stock at the redemption price of
$52.50 per share plus unpaid accumulated preferred dividends.  The Series A
Preferred Stock is currently not publicly traded.

        Holders of the Company's Series A Preferred Stock are entitled to one
vote per share on all matters submitted to a vote of stockholders.  Voting for
the election of directors is not cumulative.  If at any time four or more semi-
annual dividends on the Series A Preferred Stock are in default, in whole or in
part, the holders of the Series A Preferred Stock as a class will be entitled to
elect four directors and the holders of the Company's Common Stock will be
entitled to elect the remaining directors.  Holders of any additional Preferred
Stock

hereafter issued may have such full or limited voting rights as are provided by
the Board of Directors.

        - Junior Series B Preferred Stock. 48,437 shares of the Company's
Preferred Stock are reserved under the Rights Agreement between the Company and
First Security Bank of Utah, N.A., in connection with the Rights associated with
the Company's Common Stock. (See "DESCRIPTION OF COMMON STOCK -- Rights Plan")
                             ---


        - Additional Series of Preferred Stock.  The Board of Directors of the
          ------------------------------------                                
Company is authorized by the Certificate of Incorporation to provide, without
further shareholder action, for the issuance of one or more series of preferred
stock.  The Board of Directors has the power to fix various terms with respect
to each series, including voting powers, designations, preferences and relative,
participating, optional or other special rights, qualifications, limitations,
restrictions and redemption, conversion or exchangeability provisions.  Holders
of any series of preferred stock issued hereunder will have no pre-emptive
rights.

        The applicable Prospectus Supplement will set forth the following
specific terms regarding the series of Preferred Stock offered thereby:  (i) the
designation, number of shares and liquidation preference per share; (ii) the
initial public offering price; (iii) the dividend rate or rates; (iv) the index,
if any, upon which the amount of dividends, if any, is determined; (v) the dates
on which dividends, if any, will accrue and be payable and the designated record
dates for determining the holders entitled to such dividends; (vi) any
redemption or sinking fund provisions; (vii) any conversion or exchange
provisions; (viii) provisions for issuance of global securities; (ix) the
currency (which may be composite currency) in which payment of dividends, if
any, shall be payable if other than United States dollars; (x) voting rights;
and (xi) any additional terms, preferences or rights.

        Under regulations adopted by the Board of Governors of the Federal
Reserve System (the "Federal Reserve Board"), if the holders of shares of any
series of preferred stock of the Company become entitled to vote for the
election of directors because the Board of Directors of the Company has failed
to declare or pay dividends on such series, such series may then be deemed a
class of "voting securities" and a holder of 25 percent or more of such series
(or a holder of five percent or more if it otherwise exercises a "controlling
influence" over the Company) may then be subject to regulation as a bank holding
company in accordance with the Bank Holding Company Act of 1956, as amended.  In
addition, at such time as such series is deemed a class of voting securities,
any other bank holding company may be required to obtain the prior approval of
the Federal Reserve Board to acquire five percent or more of such series and any
person other than a bank holding company may be required to obtain the prior
approval of the Federal Reserve Board to acquire ten percent or more of such
series.

        The shares of Preferred Stock will, when issued, be fully paid and
nonassessable and will have no pre-emptive rights.

        The transfer agent, registrar, dividend disbursing agent and redemption
agent for the Preferred Stock will be specified in the Prospectus Supplement
relating thereto.

                                      24

        Because the Company is a holding company, its rights, the rights of its
creditors and of its stockholders, including the holders of any shares of
Preferred Stock, to participate in any distribution of assets of any subsidiary
upon the latter's liquidation or recapitalization will be subject to the prior
claims of the subsidiary's creditors, except to the extent that the Company may
itself be a creditor with recognized claims against the subsidiary.  The
principal sources of the Company's revenues are dividends received from its
subsidiary Banks.  Various statutory provisions limit the amount of dividends
the Company's subsidiary Banks and certain nonbank subsidiaries can pay without
regulatory approval, and various regulations can also restrict the payment of
dividends.  Certain proposed regulations could further limit the ability of the
Company's subsidiary Banks to pay dividends to the Company, and federal statutes
limit the ability of subsidiary Banks to make loans to the Company.  See
"Supervision and Regulation."

  Dividends
  ---------

        The holders of the Preferred Stock of each series will be entitled to
receive, when, as and if declared by the Board of Directors of the Company, out
of funds legally available therefor, cumulative or non-cumulative cash or other
dividends at such rate or rates and on such dates as will be set forth in the
Prospectus Supplement relating to such series.  Such rates may be fixed or
variable or both.  If variable, the formula used for determining the dividend
rate for each dividend period will be set forth in the Prospectus Supplement.
Dividends will be payable to the holders of record as they appear on the stock
books of the Company on such record dates as will be fixed by the Board of
Directors of the Company and specified in the Prospectus Supplement.  If the
Board of Directors of the Company fails to declare a dividend payable on a
dividend payment date on any series of the Preferred Stock for which dividends
are noncumulative ("Noncumulative Preferred Stock"), then the holders of such
series of the Preferred Stock will have no right to receive a dividend in
respect of the dividend period ending on such dividend payment date, and the
Company will have no obligation to pay a dividend for such period, whether or
not dividends on such series are declared payable on any future dividend payment
dates.

        No dividends may be declared in respect of any dividend period on any
other series or class of preferred stock ranking on a parity as to dividends
unless full cumulative dividends on all outstanding shares of each series of
Preferred Stock on which dividends are cumulative shall have been paid in full
or contemporaneously are declared and paid through the most recent dividend
payment date, unless otherwise indicated in the Prospectus Supplement.  In the
event that full cumulative dividends on such Preferred Stock have not been
declared and paid or set apart when due, the Company may not declare or pay any
dividends on, or make other distributions on or make any payment on account of
the purchase, redemption, or other retirement, of its Common Stock or any other
stock of the Company ranking as to dividends or upon liquidations junior to such
Preferred Stock (other than, in the case of dividends or distributions,
dividends or distributions paid in shares of, or options, warrants or rights to
subscribe for or purchase shares of, Common Stock or such other junior ranking
stock), unless full cumulative dividends on such Preferred Stock are made or set
apart for payment, unless otherwise indicated in the Prospectus Supplement.

                                      25
<PAGE>
 
  Redemption
  ----------

        The shares of any series of Preferred Stock may be redeemable at the
option of the Company and may be subject to mandatory redemption pursuant to a
sinking fund or otherwise, in each case upon the terms, on the date or dates and
at the redemption price or prices set forth in the Prospectus Supplement related
to such series.  If fewer than all shares of Preferred Stock are to be redeemed,
the shares to be redeemed shall be selected by the Company pro rata or by lot,
or by any other method determined by the Board of Directors to be equitable.
Under regulations of the Federal Reserve Board, any perpetual preferred stock
redeemable at the option of the Company may qualify as Tier 1 or Tier 2 capital
only if the redemption is subject to prior approval of the Federal Reserve
Board.  Therefore, any redemption of Preferred Stock at the option of the
Company will require the prior approval of the Federal Reserve Board in order
for the Preferred Stock to qualify as capital for bank regulatory purposes.

        If any dividends on shares of any series of Preferred Stock are in
arrears, no shares of Common Stock or shares of capital stock ranking junior to
or on parity with the Preferred Stock shall be redeemed and no shares of such
series of Preferred Stock shall be redeemed unless all outstanding shares of
such series are simultaneously redeemed, and the Company shall not purchase or
otherwise acquire any shares of such series; provided, however, that the
foregoing shall not prevent the purchase or acquisition of shares of such series
pursuant to a purchase or exchange offer made on the same terms to holders of
all outstanding shares of such series.

        Notice of redemption shall be given by mailing to each record holder of
the shares to be redeemed, not less than 40 days nor more than 70 days prior to
the date fixed for the redemption thereof, to the respective addresses of such
holders as the same shall appear on the Company's stock books.  Each such notice
shall state: (i) the redemption date; (ii) the number of shares and series of
the Preferred Stock to be redeemed; (iii) the redemption price and the manner in
which such redemption price is to be paid and delivered; (iv) the place or
places where certificates for such shares of Preferred Stock are to be
surrendered for payment of the redemption price; and (v) that dividends on the
shares to be redeemed will cease to accrue on such redemption date.  If fewer
than all shares of any series of the Preferred Stock held by any holder are to
be redeemed, the notice mailed to such holder shall also specify the number of
shares to be redeemed from such holder.

        If notice of redemption has been given, from and after the redemption
date for the shares of the series of the Preferred Stock called for redemption
(unless default shall have occurred by the Company in providing money for the
payment of the redemption price of the shares so called for redemption),
dividends on the shares of Preferred Stock so called for redemption will cease
to accrue, any right to convert the shares of Preferred Stock will terminate,
such shares will no longer be deemed to be outstanding, and all rights of the
holders thereof as stockholders of the Company (except the right to receive the
redemption price) will cease.  Upon surrender in accordance with such notice of
the certificates representing any shares so redeemed (properly endorsed or
assigned for transfer, if the Board of Directors of the Company will so require
and the notice shall so state), the redemption price set forth above will be
paid out of funds provided by the Company.  If fewer than all of the

                                      26
<PAGE>
 
shares represented by any such certificate are redeemed, a new certificate will
be issued representing the unredeemed shares without cost to the holder thereof.


  Liquidation Preference
  ----------------------

        Upon any liquidation, dissolution or winding up of the Company, the
holders of shares of each series of Preferred Stock shall be entitled to receive
out of the assets of the Company available for distribution to stockholders,
before any distribution of assets is made to or set apart for the holders of
Common Stock or of any other shares of stock of the Company ranking as to such a
distribution junior to the shares of such series, with respect to the Preferred
Stock, an amount described in the Prospectus Supplement relating to such series
of Preferred Stock.  If, in any case of any such liquidation, dissolution or
winding up of the Company, the assets of the Company or the proceeds thereof
shall be insufficient to pay in full the amounts payable with respect to shares
of each series of Preferred Stock, and any other shares of stock of the Company
ranking as to any such distribution on a parity therewith, the holders of shares
of such series of Preferred Stock and of such other shares will share ratably in
any such distribution of assets of the Company in proportion to the full
respective preferential amounts to which they are entitled.  After payment to
the holders of shares of such series of Preferred Stock of the full preferential
amounts to which they are entitled, the holders of shares of such series of
Preferred Stock will not be entitled to any further participation in any
distribution of assets by the Company, unless otherwise provided in the
Prospectus Supplement.  A consolidation or merger of the Company with one or
more corporations shall not be deemed to be a liquidation, dissolution or
winding up of the Company.

        The terms, if any, on which shares of any series of Preferred Stock are
convertible into or exchangeable for Debt Securities or Common Stock will be set
forth in the Prospectus Supplement relating thereto.  Such terms may include
provisions for conversion or exchange, either mandatory, at the option of the
holder, or at the option of the Company, in which the number of shares of Common
Stock to be received by the holders of Preferred Stock would be calculated
according to the market price of Common Stock as of a time stated in the
Prospectus Supplement.



                          DESCRIPTION OF COMMON STOCK

          The following description of the Common Stock sets forth certain
general terms and provisions of the Common Stock to which any Prospectus
Supplement may relate, including a Prospectus Supplement providing that Common
Stock will be issuable in conversion of or exchange for Debt Securities or
Preferred Stock issued by the Company.  The statements below describing the
Common Stock are in general terms and are in all respects subject to and
qualified in their entirety by reference to the applicable provisions of the
Company's Certificate of Incorporation and By-laws.

                                      27
<PAGE>
 
  General
  -------

        The Company is currently authorized to issue 150,000,000 shares of
Common Stock with a par value of $1.25 per share.  As of December 31, 1993,
there were outstanding 48,436,565 shares (net of shares held as Treasury Stock)
of the Company's Common Stock.  At such date, there were an additional 416,350
shares reserved for issuance under the Company's Comprehensive Management
Incentive Plan as stock bonuses and other awards; 352,670 shares reserved for
issuance under the Company's Dividend Reinvestment Plan; 162,761 shares reserved
for issuance upon the conversion of the Company's Series A Preferred Stock, and
2,532,599 shares reserved for issuance upon exercise of outstanding stock
options.

        The Company's Common Stock has no pre-emptive or conversion rights.

        The Company's Common Stock is not subject to redemption by the Company,
and there is no restriction on the repurchase by the Company of shares of the
Company's Common Stock except for certain regulatory limits.

  Voting
  ------

        The holders of the Company's Common Stock are entitled to voting rights
for the election of directors and for other purposes, subject to the voting
rights of the holders of Preferred Stock conferred by law and to the specific
voting rights granted to each series of Preferred Stock and to voting rights
which may in the future be granted to subsequently created series of Preferred
Stock.

  Dividends
  ---------

        Dividends will be determined by the Company's Board of Directors in
light of circumstances existing at the time, including the earnings and
financial condition of the Company, and there is no assurance that dividends
will continue to be paid at current levels.  No material restrictions have been
imposed on the Company's ability to pay dividends from its earned surplus by
bank regulations or applicable law.  As of December 31, 1993, approximately
$659.92 million could be applied to dividend payments to its shareholders and
certain other payments.  Payment of dividends on the Company's Common Stock is
also subject to the prior rights of the Company's outstanding Preferred Stock.

  Rights Plan
  -----------

        As of August 28, 1989, the Company adopted a Shareholder Rights
Agreement (the "Plan") and the Board of Directors of the Company on that date
(a) declared a dividend of one "Right" for each share of the Company's Common
Stock held of record as of the close of business on September 8, 1989, and (b)
authorized the issuance of one Right in respect of each share of the Company's
Common Stock issued after September 8, 1989 and prior to the occurrence of
certain events described in the Plan, primarily involving the acquisition of
target levels of the Company's shares by persons not then holding such amounts.
Each Right entitles the registered holder to purchase from the Company a unit
consisting of one-thousandth of a share of Junior Series B Preferred Stock at a
purchase price of $44.44

                                      28
<PAGE>
 
per unit.  The Rights are attached to all shares of the Company's Common Stock
that were outstanding on September 8, 1989 or have been issued since that date,
and no separate Rights Certificates have been or will be distributed until the
occurrence of certain events described in the Rights Agreement.  Until the
occurrence of such events, no Right may be exercised or traded separately from
the Company's Common Stock.  Following separation, the Rights may, depending
upon the occurrence of certain events described in the Rights Agreement, entitle
the holders thereof to either purchase or receive additional shares of the
Company's Common Stock.  The Rights will expire at the close of business on
August 28, 1999, unless earlier redeemed by the Company, which may be done at
$0.01 per Right, in accordance with the terms of the Plan.

        The Plan is designed to protect the Company's stockholders' interests in
the event of an unsolicited attempt to acquire the Company, including a gradual
accumulation of shares in the open market.  The Company believes that the Plan
provides protection against a partial or two-tier tender offer that does not
treat all stockholders equally and against other coercive takeover tactics which
could impair the Company's Board of Directors' ability to represent the
Company's stockholders fully.  Management believes that the Rights should also
deter any attempt by a controlling stockholder to take advantage of the Company
through self-dealing transactions.  The Plan is not intended to prevent a
takeover of the Company.  Issuing the Rights has no dilutive effect, does not
affect reported earnings per share, and does not change the way in which the
Company's shares are traded.  However, the exercise of Rights by some but not
all of the Company's stockholders would have a dilutive effect on nonexercising
stockholders.  Moreover, some may argue that the Plan has the potential for
"entrenching" current management by allowing current voting stockholders to
increase their voting shares, thus making a tender offer more difficult and
costly.

  Supermajority Vote Requirement
  ------------------------------

        The Company's Certificate of Incorporation provides that, in general, an
affirmative vote of not less than 80% of the outstanding shares of the Company's
Common Stock is required to approve or authorize certain major corporate
transactions involving the Company and holders of more than 15% of the Company's
Common Stock (including certain mergers, substantial dispositions of assets,
liquidation or dissolution, or recapitalization).  The 80% vote is not required
in some such circumstances, including certain transactions which have been
approved in advance by a majority of the Board of Directors, or where holders of
the Company's Common Stock receive a price per share that satisfies the fairness
criteria set forth in the Certificate of Incorporation.

Section 203 of the Delaware General Corporation Law

        Section 203 ("Section 203") of the Delaware General Corporation Law (the
"DGCL") applies to Delaware corporations with a class of voting stock listed on
a national securities exchange, authorized for quotation on an inter-dealer
quotation system or held of record by 2,000 or more persons.  In general,
Section 203 prevents an "interested stockholder" (defined generally as any
person owning, or who is an affiliate or associate of the corporation and has
owned in the preceding three years, 15% or more of a corporation's outstanding
voting stock and the affiliates and associates of such person) from engaging in
a "business combination" (as defined) with a Delaware corporation for three
years following

                                      29
<PAGE>
 
the date such person became an interested stockholder, unless (i) before such
person became an interested stockholder, the board of directors of the
corporation approved either the business combination or the transaction in which
the interested stockholder became an interested stockholder; (ii) upon
consummation of the transaction that resulted in the stockholder becoming an
interested stockholder, the interested stockholder owned at least 85% of the
voting stock of the corporation outstanding at the time the transaction
commenced (excluding stock held by directors who are also officers of the
corporation and by employee stock plans that do not provide employees with the
right to determine confidentially whether shares held subject to the plan will
be tendered in a tender or exchange offer); or (iii) on or subsequent to the
date such person became an interested stockholder, the business combination is
approved by the board of directors of the corporation and authorized at a
meeting of stockholders by the affirmative vote of the holders of two-thirds of
the outstanding voting stock of the corporation not owned by the interested
stockholder.  Under Section 203, the restrictions described above also do not
apply to certain business combinations proposed by an interested stockholder
following the announcement or notification of one of certain extraordinary
transactions involving the corporation and a person who had not been an
interested stockholder during the previous three years or who became an
interested stockholder with the approval of a majority of the corporation's
directors.

        Section 203 could have the effect of delaying, deferring or preventing a
change of control of the Company.

Limitation of Directors' Liability

        The DGCL authorizes corporations to limit or eliminate the personal
liability of directors, to the corporation and its stockholders, for monetary
damages in connection with the breach of a director's fiduciary duty of care.
The duty of care requires that, when acting on behalf of the corporation,
directors must exercise an informed business judgment based on all material
information reasonably available to them.  Absent the limitation authorized by
the Delaware statute, directors could be accountable to corporations and their
stockholders for monetary damages for conduct that does not satisfy such duty of
care.  Although the statute does not change a director's duty of care, it
enables corporations to limit available relief to equitable remedies such as
injunction or rescission.  The Company's Certificate of Incorporation limits the
liability of the Company's directors to the Company or its stockholders to the
fullest extent permitted by the Delaware statute as in effect from time to time.
Specifically, directors of the Company will not be personally liable for
monetary damages for breach of a director's fiduciary duty as a director, except
for liability (i) for any breach of the director's duty of loyalty to the
Company or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) for
unlawful payments of dividends or unlawful stock repurchases or redemptions as
provided in Section 174 of the DGCL or (iv) for any transaction from which the
director derived an improper personal benefit.

        The inclusion of this provision in the Certificate of Incorporation may
have the effect of reducing the likelihood of derivative litigation against
directors and may discourage or deter stockholders or management from bringing a
lawsuit against directors for breach of their duty of care, even though such an
action, if successful, might otherwise have benefitted the Company and its
stockholders.  This provision does not affect a director's responsibilities

                                      30
<PAGE>
 
under certain other laws such as the federal securities laws or state or federal
environmental laws.

Officer and Director Indemnification

        The Company's Bylaws require indemnification of the Company's directors
and executive officers to the full extent permitted by the DGCL, except in
connection with an action initiated by such officer or director or in an action
against the Company, its directors, officers, employees or agents, unless (i)
such indemnification is expressly required by law, (ii) the proceeding in
question was authorized by the Board of Directors or (iii) such indemnification
is otherwise authorized by the DGCL.  The Company's Bylaws provide that the
Company shall have the power, but shall not be required, to indemnify its other
officers, employees and agents as set forth in the DGCL.

        The Company provides liability insurance for its officers and directors
for certain losses arising from claims or charges which may be made against them
while acting in their capacities as directors or officers of the Company.



                      DESCRIPTION OF COMMON STOCK WARRANTS

        The Company may issue Common Stock Warrants for the purchase of a
particular series of Common Stock.  The Common Stock Warrants are to be issued
under warrant agreements (each a "Common Stock Warrant Agreement") to be entered
into between the Company and First Security Bank, Utah, N.A., as warrant agent
(the "Common Stock Warrant Agent"), all as set forth in the Prospectus
Supplement relating to the particular issue of Common Stock Warrants (the
"Offered Common Stock Warrants").  A copy of the Common Stock Warrant Agreement,
including the form of common stock warrant certificate (the "Common Stock
Warrant Certificate") representing the Common Stock Warrants, substantially in
the form in which it will be executed, is filed as an exhibit to the
Registration Statement.  The following summaries of certain provisions of the
Common Stock Warrant Agreement and Common Stock Warrant Certificates do not
purport to be complete and are subject to, and are qualified in their entirety
by reference to, all the provisions of the Common Stock Warrant Agreement and
the Common Stock Warrant Certificates, respectively, including the definitions
therein of certain terms.

General

        If Common Stock Warrants are offered, the Prospectus Supplement will
describe the terms of the Offered Common Stock Warrants, and the Common Stock
Warrant Agreement relating to the Offered Common Stock Warrants and the Common
Stock Warrant Certificates representing the Offered Common Stock Warrants
including the following:

             (i)   the number of shares of Common Stock purchasable upon 
        exercise of Common Stock Warrants and the price at which such number of
        shares of Common Stock may be purchased upon such exercise;

                                      31
<PAGE>
 
             (ii)  the date on which the right to exercise such Common Stock
        Warrants shall commence and the date (the "Expiration Date") on which
        such right shall expire;

            (iii)  United States Federal income tax consequences applicable to
        such Common Stock Warrants; and

             (iv)  any other terms of such Common Stock Warrants.

        Common Stock Warrants for the purchase of Common Stock will be offered
and exercisable for U.S. dollars only.  Common Stock Warrants will be issued in
registered form only.  The exercise price for Common Stock Warrants will be
subject to adjustment in accordance with the applicable Prospectus Supplement.

Exercise of Common Stock Warrants

        Each Common Stock Warrant will entitle the holder to purchase for cash
such number of shares (as applicable) of Common Stock, at such exercise price as
shall in each case be set forth in, or calculable from, the Prospectus
Supplement relating to the Offered Common Stock Warrants, which exercise price
may be subject to adjustment upon the occurrence of certain events as set forth
in such Prospectus Supplement.  Offered Common Stock Warrants may be exercised
at any time up to the close of business of the Expiration Date set forth in the
Prospectus Supplement relating to the Offered Common Stock Warrants.  After the
close of business on the Expiration Date (or such later date to which such
Expiration Date may be extended by the Company), unexercised Common Stock
Warrants will become void.  The place or places where, and the manner in which,
Common Stock Warrants may be exercised shall be specified in the Prospectus
Supplement relating to such Common Stock Warrants.

        Prior to the exercise of any Common Stock Warrants to purchase Common
Stock, holders of such Common Stock Warrants will not have any rights of holders
of the Common Stock purchasable upon such exercise, including the right to
receive payments of dividends, if any, on the Common Stock purchasable upon such
exercise or to exercise any applicable right to vote.



                              PLAN OF DISTRIBUTION

        The Company may sell the Securities (i) through agents, (ii) through
underwriters, (iii) through dealers and (iv) directly to purchasers.

        Securities may be offered and sold through agents designated by the
Company from time to time.  Any such agent involved in the offer or sale of the
Securities will be named, and any commissions payable by the Company to such
agent will be set forth, in the Prospectus Supplement.  Unless otherwise
indicated in the Prospectus Supplement, any such agent will be acting on a best
efforts basis for the period of its appointment.  Any such agent may be deemed
to be an underwriter, as that term is defined in the Securities Act of 1933,

                                      32
<PAGE>
 
as amended, of the Securities so offered and sold.  Agents may be entitled under
agreements which may be entered into with the Company to indemnification by the
Company against certain liabilities, including liabilities under the Securities
Act of 1933, as amended.

        If an underwriter or underwriters are utilized in the sale of the
Offered Securities, the Company will execute an underwriting agreement with such
underwriter or underwriters at the time an agreement for such sale is reached,
and the names of the specific managing underwriter or underwriters, as well as
any other underwriters, and the terms of the transaction, including compensation
of the underwriters and dealers, if any, will be set forth in the Prospectus
Supplement which will be used by the underwriters to make resales of the
Securities.  Underwriters will acquire Securities for their own account and may
resell such Securities from time to time in one or more transactions, including
negotiated transactions, at fixed public offering prices or at varying prices
determined at the time of sale.  Securities may be offered to the public either
through underwriting syndicates represented by managing underwriters, or
directly by the managing underwriters.  The underwriters may be entitled, under
the relevant underwriting agreement, to indemnification by the Company against
certain liabilities, including liabilities under the Securities Act of 1933, as
amended.  If an underwriter is utilized in the sale of the Securities, the
underwriting agreement will provide that the obligations of the underwriter is
subject to certain conditions precedent and that the underwriter with respect to
a sale of Securities will be obligated to purchase all such Securities if any
are purchased.

        If a dealer is utilized in the sale of the Securities, the Company will
sell such Securities to the dealer, as principal.  The dealer may then resell
such Securities to the public at varying prices to be determined by such dealer
at the time of resale.  Any such dealer may be deemed to be an underwriter, as

companies, educational and charitable institutions and other institutions but
shall in all cases be subject to the approval of the Company.

        Contracts will not be subject to any conditions except that any related
sale of Securities to underwriters shall have occurred and the purchase by an
institution of the Securities covered by its Contract shall not at the time of
delivery be prohibited under the laws of any jurisdiction in the United States
to which such institution is subject.  A commission indicated in the Prospectus
Supplement will be paid to underwriters and agents soliciting purchases of
Offered Securities pursuant to Contracts accepted by the Company.

        The place and time of delivery of the Securities are set forth in the
accompanying Prospectus Supplement.

Association of Securities Dealers, Inc. regarding underwriting of securities of
an affiliate.

        Certain of the underwriters or agents and their associates may be
customers of, engage in transactions with, and perform services for, the Company
in the ordinary course of business.

Item 15.  Indemnification of Directors and Officers.

              Indemnification.  Delaware law provides that a director, employee,
              ---------------                                                   
officer or agent of a corporation may be indemnified against liability (other
than in an action by or in the right of the corporation) and other costs
incurred by such person in connection with such proceeding, provided such person
acted in good faith and in a manner such person reasonably believed to be in,
and not opposed to, the best interests of the corporation, and, with respect to
any criminal proceeding, had no reason to believe the conduct was unlawful.  For
actions or suits brought by or in the name of the corporation, Delaware provides
that a director, employee, officer or agent of a corporation may be indemnified
against expenses incurred by such person in connection with such proceeding if
such person acted in good faith and in a manner such person reasonably believed
to be in and not opposed to, the best interests of the corporation, except that
if such person is adjudged to be liable to the corporation, such person can be
indemnified if and only to the extent that a court determines that despite the
adjudication of liability, in view of all the circumstances of the case, such
person is fairly and reasonably entitled to indemnity for such expenses as the
court shall deem proper.  On the other hand, if he/she prevails, indemnification
is mandatory.  Under Delaware law, the determination of whether an officer or
director is entitled to indemnification (that is, whether or not the person has
met the statutory standard of conduct required for indemnification) is to be
made in certain circumstances by independent legal counsel.  First Security
Corporation's Articles of Incorporation, as amended, provide for indemnification
of such persons to the full extent allowed by applicable law.  The proposed
forms of Underwriting Agreement and Distribution Agreement, filed as Exhibits
1(a) and 1(b), respectively, to this Registration Statement provide for
indemnification of the Company's officers and directors

                                    II-1

who signed the Registration Statement against certain liabilities, including
liabilities under the Securities Act of 1933.

              Director's Liability.  Delaware allows a corporation to provide, 
              --------------------
in its articles or certificate of incorporation, a provision which limits or
eliminates the personal liability of a director to the corporation and its
shareholders or stockholders for monetary damages for such person's breach of
fiduciary duty, provided that such provision may not so limit a director's
liability (i) for a breach of his or her duty of loyalty to the corporation;
(ii) for acts or omissions not in good faith or involving intentional misconduct
or a knowing violation of law; (iii) for unlawful payments of dividends, certain
stock repurchases or redemptions; or (iv) for any transaction from which the
director derived an improper personal benefit.

              These provisions have the effect of protecting a corporation's
directors against personal liability from breaches of their duty of care.  First
Security Corporation, with the approval of its stockholders, amended its
Certificate of Incorporation to include such provisions in 1988.

          * To be filed by amendment

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; and

                   (iii) To include any material information with respect to
               the plan of distribution not previously disclosed in the
               registration statement or any material change to such information
               in the registration statement;

                                     II-3
<PAGE>
 
          provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if
          the information required to be included in a post-effective amendment
          by those paragraphs is contained in periodic reports filed by the
          registrant pursuant to Section 13 or Section 15(d) of the Securities
          Exchange Act of 1934 that are incorporated by reference in the
          registration statement.

               (2)  That, for the purpose of determining any liability under the
          Securities Act of 1933, each such post-effective amendment shall be
          deemed to be a new registration statement relating to the securities
          offered therein, and the offering of such securities at that time
          shall be deemed to be the initial bona fide offering thereof.

               (3)  To remove from registration by means of a post-effective
          amendment any of the securities being registered which remain unsold
          at the termination of the offering.

          The undersigned registrant hereby further 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 each filing of the registrant's
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities 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.

          Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the provisions described under Item 15
above, or otherwise, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable.  In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate  jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

          The undersigned registrant hereby undertakes that:

               (1)  For purposes of determining any liability under the
          Securities Act of 1933, the information omitted from the form of
          prospectus filed as part of this registration statement in reliance
          upon Rule 430A and contained in a form of prospectus filed by the
          registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the
          Securities Act shall be deemed to be part of this registration
          statement as of the time it was declared effective.

<PAGE>
 
               (2) For the purpose of determining any liability under the
          Securities Act of 1933, each post-effective amendment that contains
          a form of prospectus 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.

registrant certifies that it has reasonable grounds to believe that it meets all

                          [Insert Title of Securities]

                             UNDERWRITING AGREEMENT
                             ----------------------


          1.  Introductory.  First Security Corporation, a Delaware corporation
              ------------                                                     
("Company"), proposes to issue and sell from time to time certain [shares] of
its [common stock] [preferred stock] [common stock warrants] [debt securities]
registered under the registration statement referred to in Section 2(a)
("Registered Securities").  [The debt securities (the "Debt Securities") will
consist of unsecured debt securities (the "Senior Debt Securities") and
unsecured, subordinated debt securities (the "Subordinated Debt Securities").
The Senior Debt Securities will be issued under an indenture, dated as of
March 1, 1994 (the "Senior Indenture"), between the Company and The First
National Bank of Chicago, as Trustee. The Subordinated Debt Securities will be
issued under an Indenture, dated as of March 1, 1994 (the "Subordinated
Indenture"), between the Company and The First National Bank of Chicago, as
Trustee. The Senior Indenture and the Subordinated Indenture, as they may be
modified by the Trust Indenture Reform Act of 1990, are each referred to
herein as an "Indenture". The Debt Securities will be issued in one or more
series, which series may have varying designations, interest rates and times
of payment of any interest, maturities, redemption provisions and other terms,
with all such terms for any particular series of the Debt Securities being
determined at the time of the sale.] [The Preferred Stock will be issued
pursuant to a Certificate of Designations filed with the Delaware Secretary of
State.] [The common stock warrants will be issued pursuant to a Common Stock
Warrant Agreement, dated ________ __, 1994, between the Company and
________________, as Warrant Agent (the "Warrant Agreement").] [The Registered
Securities will, to the extent provided in the Terms Agreement referred to in
Section 3, be convertible at the option of the holder thereof into [shares of
the Company's Common Stock, par value $1.25 per share (the "Common Stock")]
[insert description of other securities into which convertible]. [The]
 -------------------------------------------------------------
[Particular series of the] Registered Securities will be sold pursuant to a
Terms Agreement referred to in Section 3, for resale in accordance with terms
of offering determined at the time of sale.]

          The Registered Securities involved in any such offering are
hereinafter referred to as the "Securities".  The firm or firms which agree to
purchase the Securities are
<PAGE>
 
hereinafter referred to as the "Underwriters" of such Securities, and the
representative or representatives of the Underwriters, if any, specified in a
Terms Agreement referred to in Section 3 are hereinafter referred to as the
"Representatives"; provided, however, that if the Terms Agreement does not
specify any representative of the Underwriters, the term "Representatives", as
used in this Agreement (other than in Sections 2(b), 5(c) and 6 and the second
sentence of Section 3), shall mean the Underwriters.

          2.  Representations and Warranties of the Company.  The Company
              ---------------------------------------------              
represents and warrants to, and agrees with, each Underwriter that:

          (a)  A registration statement (No. ___-________), including a
     prospectus, relating to the Registered Securities has been filed with the
     Securities and Exchange Commission ("Commission") and has become effective.
     Such registration statement, as amended at the time of any Terms Agreement
     referred to in Section 3, is hereinafter referred to as the "Registration
     Statement", and the prospectus included in such Registration Statement, as
     supplemented as contemplated by Section 3 to reflect the terms of the
     Securities and the terms of offering thereof, as first filed with the
     Commission pursuant to and in accordance with Rule 424(b) ("Rule 424(b)")
     under the Securities Act of 1933 ("Act"), including all material
     incorporated by reference therein, is hereinafter referred to as the
     "Prospectus".

          (b)  On the effective date of the registration statement relating to
     the Registered Securities, such registration statement conformed in all
     respects to the requirements of the Act[, the Trust Indenture Act of 1939
     ("Trust Indenture Act")] and the rules and regulations of the Commission
     ("Rules and Regulations"), and did not include any untrue statement of a
     material fact or omit to state any material fact required to be stated
     therein or necessary to make the statements therein not misleading; and on
     the date of each Terms Agreement referred to in Section 3, at each Closing
     Date referred to in Section 3 and at the time of filing of the Prospectus
     pursuant to Rule 424(b), the Registration Statement and the Prospectus will
     conform in all respects to the requirements of the Act[, the Trust
     Indenture Act] and the Rules and Regulations, and neither of such documents
     will include any untrue statement of a material fact or omit to state any
     material fact required to be stated therein or necessary to make the
     statements therein not mislead-

                                       2
<PAGE>
 
     ing, except that the foregoing does not apply to statements in or omissions
     from any of such documents based upon written information furnished to the
     Company by any Underwriter through the Representatives, if any,
     specifically for use therein.

          (c)  The financial statements, and the related notes thereto, included
     or incorporated by reference in the Registration Statement and the
     Prospectus present fairly the consolidated financial position of the
     Company and its consolidated subsidiaries as of the dates indicated and the
     results of their operations and the changes in their consolidated cash
     flows for the periods specified; said financial statements have been
     prepared in conformity with generally accepted accounting principles
     applied on a consistent basis, and the supporting schedules included or
     incorporated by reference in the Registration Statement present fairly the
     information required to be stated therein.

          (d)  Since the respective dates as of which information is given in
     the Registration Statement and the Prospectus, there has not been any
     material adverse change, or any development involving a material adverse
     change, in or affecting the general affairs, business, prospects,
     management, financial position, stockholders' equity or results of
     operations of the Company and its subsidiaries, taken as a whole, otherwise
     than as set forth or contemplated in the Prospectus; and except as set
     forth or contemplated in the Prospectus neither the Company nor any of its
     subsidiaries has entered into any transaction or agreement (whether or not
     in the ordinary course of business) material to the Company and its
     subsidiaries taken as a whole.

          (e)  The Company has been duly incorporated and is validly existing as
     a corporation in good standing under the laws of the state of Delaware,
     with corporate power and authority to own its properties and conduct its
     business as described in the Prospectus; and the company is duly qualified
     to do business as a foreign corporation in good standing in all other
     jurisdictions in which it owns properties or leases properties or the
     conduct of its business requires such qualification.

          (f)   Each of the Company's subsidiaries has been duly incorporated
     and is validly existing as a corporation in good standing under the laws of
     its jurisdiction of incorporation, with corporate power and authority to
     own its properties and conduct its

                                       3
<PAGE>
 
     business as described in the Prospectus, and has been duly qualified to do
     business as a foreign corporation in good standing in all other
     jurisdictions in which it owns properties or leases properties or the
     conduct of its business requires such qualification, other than where the
     failure to be so qualified or in good standing would not have a material
     adverse effect on the Company and its subsidiaries taken as a whole; and
     all the outstanding shares of capital stock of each subsidiary of the
     Company have been duly authorized and validly issued, are fully-paid and
     non-assessable, and (except in the case of foreign subsidiaries, for
     directors' qualifying shares) are owned by the Company, directly or
     indirectly, free and clear of all liens, encumbrances, security interests
     and claims.

          3.  Purchase and Offering of Securities.  The obligation of the
              -----------------------------------                        
Underwriters to purchase the Securities will be evidenced by an exchange of
telegraphic or other written communications ("Terms Agreement") at the time the
Company determines to sell the Securities.  Each Terms Agreement shall be
substantially in the form attached hereto as Annex I and will incorporate by
reference the provisions of this Agreement, except as otherwise provided
therein, and will specify the firm or firms which will be Underwriters, the
names of any Representatives, the [principal amount of] [number of] [shares of]
Securities to be purchased by each Underwriter, the purchase price to be paid by
the Underwriters, the nature of the funds to be delivered by the Underwriters
[and] [,] the public offering price, if any [if Debt Securities, insert --, and
                                             -----------------------------     
the terms of the Securities not already specified in the Indenture, including,
but not limited to, interest rate, if any, maturity, any redemption provisions
and any sinking fund requirements] [if Preferred Stock, insert --, and the terms
                                    -----------------------------               
of the Securities not already specified in the Certificate of Designations,
including, but not limited to, annual dividend rates, sinking fund provisions,
if any, and redemption provisions, if any] [if Warrants, insert --, and the
                                            ----------------------         
terms of the Securities not already specified in the Warrant Agreement,
including, but not limited to, the type of securities issuable on exercise of
one Warrant, the Warrant exercise price, the date after which Warrants are
exercisable and the Warrant expiration date], and whether any of the Securities
may be sold to institutional investors pursuant to Delayed Delivery Contracts
(as defined below).  Each Terms Agreement will also specify the time and date of
delivery and payment (such time and date, or such other time not later than
seven full business days thereafter as the Representatives and the Company agree
as the time for payment and delivery, being herein and in the Terms Agreement
referred to as the

                                       4
<PAGE>
 
"Closing Date"), the place of delivery and payment and any details of the terms
of offering that should be reflected in the prospectus supplement relating to
the offering of the Securities.  The obligations of the Underwriters to purchase
the Securities will be several and not joint.  It is understood that the
Underwriters propose to offer the Securities for sale as set forth in the
Prospectus.  The Securities delivered to the Underwriters on the Closing Date
will be in definitive fully registered form, in such denominations and
registered in such names as the Underwriters may request.

          If any Terms Agreement provides for sales of Securities pursuant to
delayed delivery contracts, the Company authorizes the Underwriters to solicit
offers to purchase Securities pursuant to delayed delivery contracts
substantially in the form of Annex II attached hereto ("Delayed Delivery
Contracts") with such changes therein as the Company may authorize or approve.
Delayed Delivery Contracts are to be with institutional investors, including
commercial and savings banks, insurance companies, pension funds, investment
companies and educational and charitable institutions.  On the Closing Date the
Company will pay, as compensation, to the Representatives for the accounts of
the Underwriters, the fee set forth in such Terms Agreement in respect of the
[principal amount of] [number of] [shares of] Securities to be sold pursuant to
Delayed Delivery Contracts ("Contract Securities").  The Underwriters will not
have any responsibility in respect of the validity or the performance of Delayed
Delivery Contracts.  If the Company executes and delivers Delayed Delivery
Contracts, the Contract Securities will be deducted from the Securities to be
purchased by the several Underwriters and the [aggregate principal amount of]
[number of] [shares of] Securities to be purchased by each Underwriter will be
reduced pro rata in proportion to the [principal amount of] [number of] [shares
of] Securities set forth opposite each Underwriter's name in such Terms Agree-
ment, except to the extent that the Representatives determine that such
reduction shall be otherwise than pro rata and so advise the Company.  The
Company will advise the Representatives not later than the business day prior to
the Closing Date of the principal amount of Contract Securities.

          4.  Certain Agreements of the Company.  The Company agrees with the
              ---------------------------------                               
several Underwriters that it will furnish to Sullivan & Cromwell, counsel for
the Underwriters, one signed copy of the registration statement relating to the
Registered Securities, including all exhibits, in the form it became effective
and of all amendments thereto and that, in connection with each offering of
Securities:

                                       5
<PAGE>
 
          (a) The Company will file the Prospectus with the Commission pursuant
     to and in accordance with Rule 424(b)(2) (or, if applicable and if
     consented to by the Representatives, subparagraph (5)) not later than the
     second business day following the execution and delivery of the Terms
     Agreement. The Company will advise you promptly of any such filing pursuant
     to Rule 424(b).

          (b)  The Company will advise the Representatives promptly of any
     proposal to amend or supplement the Registration Statement or the
     Prospectus, and will afford the Representatives a reasonable opportunity to
     comment on any such proposed amendment or supplement; and the Company will
     also advise the Representatives promptly of the filing of any such
     amendment or supplement and of the institution by the Commission of any
     stop order proceedings in respect of the Registration Statement or of any
     part thereof and will use its best efforts to prevent the issuance of any
     such stop order and to obtain as soon as possible its lifting, if issued.

          (c)  If, at any time when a prospectus relating to the Securities is
     required to be delivered under the Act, any event occurs as a result of
     which the Prospectus as then amended or supplemented would include an
     untrue statement of a material fact or omit to state any material fact
     necessary to make the statements therein, in the light of  the
     circumstances under which they were made, not misleading, or if it is
     necessary at any time to amend or supplement the Registration Statement or
     Prospectus to comply with the Act, the Company promptly will prepare and
     file with the Commission an amendment or supplement which will correct such
     statement or omission or an amendment which will effect such compliance.
     Neither the Representatives' consent to, nor the Underwriters' delivery
     of, any such amendment or supplement shall constitute a waiver of any of
     the conditions set forth in Section 5.

          (d)  As soon as practicable, but not later than 16 months after the
     date of each Terms Agreement, the Company will make generally available to
     its securityholders an earnings statement covering a period of at least 12
     months beginning after the later of (i) the effective date of the
     registration statement relating to the Registered Securities, (ii) the
     effective date of the most recent post-effective amendment to the
     Registration Statement to become effective prior to the date of such Terms
     Agreement and (iii) the date of the

                                       6
<PAGE>
 
     Company's most recent Annual Report on Form 10-K filed with the Commission
     prior to the date of such Terms Agreement, which will satisfy the
     provisions of Section 11(a) of the Act.

          (e)  The Company will furnish to counsel for the Underwriters, one
     signed copy of the Registration Statement, including all exhibits, relating
     to the Securities [and any [shares of Common Stock] [insert other
                                                          ------------
     securities into which convertible] issuable upon conversion or exercise of
     ---------------------------------                                         
     the Securities] in the form in which it became effective and of all
     amendments thereto and will furnish to the Representatives copies of the
     Registration Statement, including all exhibits, any related preliminary
     prospectus, any related preliminary prospectus supplement, the Prospectus
     and all amendments and supplements to such documents, in each case as soon
     as available and in such quantities as are reasonably requested.

          (f)  The Company will arrange for the qualification of the Securities
     [and any [shares of Common Stock] [insert other securities into which
                                        ----------------------------------
     convertible] issuable upon conversion or exercise of the Securities] for
     -----------                                                             
     sale and the determination of their eligibility for investment under the
     laws of such jurisdictions as the Representatives designate and will

              --------------------------------------------------      
obligations of the several Underwriters to purchase and pay for the Securities
will be subject to the accuracy of the representations and warranties on the
part of the Company herein as of the date hereof and the Closing Date, to the
accuracy of the statements of Company officers made pursuant to the provisions
hereof, to the performance by the Company of its obligations hereunder and to
the following additional conditions precedent:

          (a)  Subsequent to the signing of this Agreement, the Representatives
     shall have received a letter, dated the date of delivery thereof, of
     Deloitte & Touche confirming that they are independent public accountants
     within the meaning of the Act and the applicable published Rules and
     Regulations thereunder and stating in effect that:

               (i) in their opinion, the financial statements and schedules
          examined by them and included in the prospectus contained in the
          registration statement relating to the Registered Securities, as
          amended at the date of such letter, comply in form in all material
          respects with the applicable accounting requirements of the Act, the
          Securities and Exchange Act of 1934 (the "Exchange Act") and the
          related published Rules and Regulations;

              (ii) they have made a review of any unaudited financial statements
          included in such prospectus in accordance with standards established
          by the American Institute of Certified Public Accountants, as
          indicated in their report or reports attached to such letter;

             (iii) on the basis of the review referred to in (ii) above, a
          reading of the latest available interim financial statements of the
          Company, inquiries of officials of the Company who have responsibility
          for financial and accounting matters and other specified procedures,
          nothing came to their attention that caused them to believe that the
          unaudited financial statements, if any, included in such prospectus do
          not comply in form in all material respects with the applicable
          accounting requirements of the Act and the related published Rules and
          Regulations or are not in conformity with generally accepted
          accounting principles applied on a basis substantially consistent
          with that of the audited financial statements included in such
          prospectus; and

                                       9
<PAGE>
 
               (iv) they have compared specified dollar amounts (or percentages
          derived from such dollar amounts) and other financial information
          contained in such prospectus (in each case to the extent that such
          dollar amounts, percentages and other financial information are
          derived from the general accounting records of the Company and its
          subsidiaries subject to the internal controls of the Company's
          accounting system or are derived directly from such records by
          analysis or computation) with the results obtained from inquiries, a
          reading of such general accounting records and other procedures
          specified in such letter and have found such dollar amounts,
          percentages and other financial information to be in agreement with
          such results, except as otherwise specified in such letter.

     All financial statements and schedules included in material incorporated by
     reference into such prospectus shall be deemed included in such prospectus
     for purposes of this subsection.

          (b)  The Prospectus shall have been filed with the Commission in
     accordance with the Rules and Regulations and Section 4(a) of this
     Agreement.  No stop order suspending the effectiveness of the Registration
     Statement or of any part thereof shall have been issued and no proceedings
     for that purpose shall have been instituted or, to the knowledge of the
     Company or any Underwriter, shall be contemplated by the Commission as of
     the Closing Date.

          (c)  Subsequent to the execution of the Terms Agreement, there shall
     not have occurred (i) any material adverse change, or any development
     involving a material adverse change, in or affecting the general affairs,
     business, prospects, management, financial position, stockholders' equity
     or results of operations of the Company and its subsidiaries, taken as a
     whole, otherwise than as set forth or contemplated in the Prospectus, the
     effect of which in the judgment of the Representatives makes it
     impracticable or inadvisable to proceed with the public offering or the
     delivery of the Securities on the terms and in the manner contemplated in
     the Prospectus; (ii) any downgrading in the rating of any debt securities
     [or preferred stock] of the Company by any "nationally recognized
     statistical rating organization" (as defined for purposes of Rule 436(g)
     under the Act), or any public announcement that any such organization has
     under sur-

                                       10
<PAGE>
 
     veillance or review its rating of any debt securities [or preferred stock]
     of the Company (other than an announcement with positive implications of a
     possible upgrading, and no implication of a possible downgrading, of such
     rating); (iii) any suspension or limitation of trading in securities
     generally on the New York Stock Exchange, or any setting of minimum prices
     for trading on such exchange, or any suspension of trading of any
     securities of the Company on any exchange or in the over-the-counter
     market; (iv) any banking moratorium declared by Federal or New York
     authorities; or (v) any outbreak or escalation of major hostilities in
     which the United States is involved, any declaration of war by Congress,
     any material adverse change in the financial markets or any other
     substantial national or international calamity or emergency if, in the
     judgment of a majority in interest of the Underwriters, including any
     Representatives, the effect of any such outbreak, escalation, declaration,
     calamity or emergency makes it impractical or inadvisable to proceed with
     completion of the sale of and payment for the Securities.

          (d)  The Representatives shall have received an opinion, dated the
     Closing Date, of Ray, Quinney & Nebeker, counsel for the Company, to the
     effect that:

               (i)  The Company has been duly incorporated and is an existing
          corporation in good standing under the laws of the State of Delaware,

          its business as described in the Prospectus; and the Company is duly
          qualified to do business as a foreign corporation in good standing in
          all other jurisdictions in which it owns properties or leases
          properties or the conduct of its business requires such qualification;

               (ii)  Each of the Company's subsidiaries has been duly
          incorporated and is validly existing as a corporation in good standing

          described in the Prospectus, and has been duly qualified to do
          business as a foreign corporation in good standing in all other
          jurisdictions in which it owns properties or leases properties or the
          conduct of its business requires such qualification, other than where
          the failure to be so qualified or in good standing would not have a
          material adverse

          effect on the Company and its subsidiaries taken as a whole; and all
          the outstanding shares of capital stock of each subsidiary of the
          Company have been duly authorized and validly issued, are fully-paid
          and non-assessable, and (except in the case of foreign subsidiaries,
          for directors' qualifying shares) are owned by the Company, directly
          or indirectly, free and clear of all liens, encumbrances, security
          interests and claims.

          of the Act and the related published Rules and Regulations;

               (ii)  they have made a review of any unaudited financial
          statements included in the Prospectus and not covered by their letter
          delivered pursuant to subsection (a) of this Section in accordance
          with standards established by the American Institute of Certified
          Public Accountants, as indicated in their report or reports attached
          to such letter;

               (iii)  on the basis of the review referred to in (ii) above, a
          reading of the latest available interim financial statements of the
          Company, inquiries of officials of the Company who have responsibility
          for financial and accounting matters and other specified procedures,
          nothing came to their attention that caused them to believe that:

                    (A)  the unaudited financial statements, if any, included in
               the Prospectus and not covered by their letter delivered pursuant
               to subsection (a) of this Section do not comply in form in all
               material respects with the applicable accounting requirements of
               the Act and the related published Rules and Regulations or are
               not in conformity with generally accepted accounting principles
               applied on a basis substantially consistent with that of the
               audited financial statements included in the Prospectus;

                    (B)  the unaudited capsule information, if any, included in
               the Prospectus does not agree with the amounts set forth in the
               unaudited consolidated financial statements from which it was
               derived or was not determined on a basis substantially
               consistent with that of the audited financial statements included
               in the Prospectus;

                    (C)  at the date of the latest available balance sheet read
               by such accountants, or at a subsequent specified date not more
               than five days prior to the Closing Date, there was any change in
               the capital stock or any increase in short-term indebtedness or
               long-

                                       17

               term debt of the Company and consolidated subsidiaries or, at the
               date of the latest available balance sheet read by such accoun-
               tants, there was any decrease in consolidated total assets, total
               deposits, reserves for loan losses or stockholders' equity or any
               change in the reserve for loan losses or other real estate, as
               compared with amounts shown on the latest balance sheet included
               in the Prospectus; or

                    (D)  for the period from the date of the latest income
               statement included in the Prospectus to the closing date of the
               latest available income statement read by such accountants there
               were any decreases, as compared with the corresponding period of
               the previous year, and with the period of corresponding length
               ended the date of the latest income statement included in the
               Prospectus, in consolidated net interest income, net interest
               income after provision for loan losses, other income or in the
               ratio of earnings to fixed charges or in the total or per share
               amounts of income or net income;

          except in all cases set forth in clauses (C) and (D) above for
          changes, increases or decreases which the Prospectus discloses have
          occurred or may occur or which are described in such letter; and

               (iv)  they have compared specified dollar amounts (or percentages
          derived from such dollar amounts) and other financial information
          included in the Prospectus and not covered by their letter delivered
          pursuant to subsection (a) of this Section (in each case to the
          extent that such dollar amounts, percentages and other financial
          information are derived from the general accounting records of the
          Company and its subsidiaries subject to the internal controls of the
          Company's accounting system or are derived directly from such records
          by analysis or computation) with the results obtained from inquiries,
          a reading of such general accounting records and other procedures
          specified in such letter and have found such dollar amounts,
          percentages and other financial information to be in agreement with
          such results, except as otherwise specified in such letter.

                                       18
<PAGE>
 
     All financial statements and schedules included in material incorporated by
     reference into the Prospectus shall be deemed included in the Prospectus
     for the purposes of this subsection.

The Company will furnish the Representatives with such con-formed copies of such
opinions, certificates, letters and documents as they reasonably request.

          6.  Indemnification and Contribution.  (a)  The Company will indemnify
              --------------------------------                                  
and hold harmless each Underwriter against any losses, claims, damages or
liabilities, joint or several, to which such Underwriter may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
the Registration Statement, the Prospectus, or any amendment or supplement
thereto, or any related preliminary prospectus or preliminary prospectus
supplement, or arise out of or are based upon the omission or alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, and will reimburse each Underwriter
for any legal or other expenses reasonably incurred by such Underwriter in
connection with investigating or defending any such loss, claim, damage,
liability or action as such expenses are incurred; provided, however, that the
Company will not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon an untrue statement or
alleged untrue statement in or omission or alleged omission from any of such
documents in reliance upon and in conformity with written information furnished
to the Company by any Underwriter through the Representatives, if any,
specifically for use therein.

          (b)  Each Underwriter will indemnify and hold harmless the Company
against any losses, claims, damages or liabilities to which the Company may
become subject, under the Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in the Registration Statement, the Prospectus, or any amendment or
supplement thereto, or any related preliminary prospectus or preliminary
prospectus supplement, or arise out of or are based upon the omission or the
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or

                                       19
<PAGE>
 
alleged omission was made in reliance upon and in conformity with written
information furnished to the Company by such Underwriter through the
Representatives, if any, specifically for use therein, and will reimburse any
legal or other expenses reasonably incurred by the Company in connection with
investigating or defending any such loss, claim, damage, liability or action as
such expenses are incurred.

          (c)  Promptly after receipt by an indemnified party under this Section
of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under
subsection (a) or (b) above, notify the indemnifying party of the commencement
thereof; but the omission so to notify the indemnifying party will not relieve
it from any liability which it may have to any indemnified party otherwise than
under subsection (a) or (b) above.  In case any such action is brought against
any indemnified party and it notifies the indemnifying party of the commencement
thereof, the indemnifying party, upon request of the indemnified party, shall
retain counsel reasonably satisfactory to the indemnified party to represent the
indemnified party and any others the indemnifying party may designate in such
proceeding and shall pay the fees and expenses of such counsel related to such
proceeding.  In any such proceeding, any indemnified party shall have the right
to retain its own counsel, but the fees and expenses of such counsel shall be at
the expense of such indemnified party unless (i) the indemnifying party and the
indemnified party shall have mutually agreed to the contrary, (ii) the
indemnifying party has failed within a reasonable time to retain counsel
reasonably satisfactory to the indemnified party or (iii) the named parties in
any such proceeding (including any impleaded parties) include both the
indemnifying party and the indemnified party and representation of both parties
by the same counsel would be inappropriate due to actual or potential differing
interests between them.  The indemnifying party shall not be liable for any
settlement of any proceeding effected without its written consent, but if
settled with such consent or if there be a final judgment for the plaintiff, the
indemnifying party agrees to indemnify any indemnified party from and against
any loss or liability by reason of such settlement or judgment.  No indemnifying
party shall, without the prior written consent of the indemnified party, effect
any settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all

                                       20
<PAGE>
 
liability on claims that are the subject matter of such proceeding.

          (d)  If the indemnification provided for in this Section is
unavailable or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above, then each indemnifying party shall contribute to
the amount paid or payable by such indemnified party as a result of the losses,
claims, damages or liabilities referred to in subsection (a) or (b) above (i)
in such proportion as is appropriate to reflect the relative benefits received
by the Company on the one hand and the Underwriters on the other from the
offering of the Securities or (ii) if the allocation provided by clause (i)
above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause (i) above but
also the relative fault of the Company on the one hand and the Underwriters on
the other in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities as well as any other relevant equitable
considerations.  The relative benefits received by the Company on the one hand
and the Underwriters on the other shall be deemed to be in the same proportion
as the total net proceeds from the offering (before deducting expenses) received
by the Company bear to the total underwriting discounts and commissions
received by the Underwriters.  The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or the Underwriters and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such untrue statement or omission.  The amount paid by an
indemnified party as a result of the losses, claims, damages or liabilities
referred to in the first sentence of this subsection (d) shall be deemed to
include any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any action or claim which is
the subject of this subsection (d).  Notwithstanding the provisions of this
subsection (d), no Underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Securities
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages which such Underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or 
omission or alleged omission.  No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

                                       21
<PAGE>
 
The Underwriters' obligations in this subsection (d) to contribute are several
in proportion to their respective underwriting obligations and not joint.

          (e)  The obligations of the Company under this Section shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each person, if any, who controls any
Underwriter within the meaning of the Act; and the obligations of the
Underwriters under this Section shall be in addition to any liability which the
respective Underwriters may otherwise have and shall extend, upon the same terms
and conditions, to each director of the Company, to each officer of the Company
who has signed the Registration Statement and to each person, if any, who
controls the Company within the meaning of the Act.

          7.  Default of Underwriters.  If any Underwriter or Underwriters
              -----------------------                                     
default in their obligations to purchase Securities under the Terms Agreement
and the aggregate principal amount of the Securities that such defaulting
Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of
the total principal amount of the Securities, the Representatives may make
arrangements satisfactory to the Company for the purchase of such Securities by
other persons, including any of the Underwriters, but if no such arrangements
are made by the Closing Date, the non-defaulting Underwriters shall be obligated
severally, in proportion to their respective commitments under this Agreement
and the Terms Agreement, to purchase the Securities that such defaulting
Underwriters agreed but failed to purchase.  If any Underwriter or Underwriters
so default and the aggregate principal amount of the Securities with respect to
which such default or defaults occur exceeds 10% of the total principal amount
of the Securities and arrangements satisfactory to the Representatives and the
Company for the purchase of such Securities by other persons are not made within
36 hours after such default, such Terms Agreement will terminate without
liability on the part of any non-defaulting Underwriter or the Company, except
as provided in Section 8.  As used in this Agreement, the term "Underwriter"
includes any person substituted for an Underwriter under this Section.  Nothing
herein will relieve a defaulting Underwriter from liability for its default.
The respective commitments of the several Underwriters for the purposes of this
Section shall be determined without regard to reduction in the respective
Underwriters' obligations to purchase the [principal amounts] [numbers of
shares] of the Securities set forth opposite their names in the Terms Agreement
as a result of Delayed Delivery Contracts entered into by the Company.

                                       22
<PAGE>
 
          The foregoing obligations and agreements set forth in this Section
will not apply if the Terms Agreement specifies that such obligations and
agreements will not apply.

          8.  Survival of Certain Representations and Obligations.  The
              ---------------------------------------------------      
respective indemnities, agreements, representations, warranties and other
statements of the Company or its officers and of the several Underwriters set
forth in or made pursuant to this Agreement will remain in full force and
effect, regardless of any investigation, or statement as to the results thereof,
made by or on behalf of any Underwriter, the Company or any of their respective
representatives, officers or directors or any controlling person and will
survive delivery of and payment for the Securities.  If the Terms Agreement is
terminated pursuant to Section 7 or if for any reason the purchase of the
Securities by the Underwriters under the Terms Agreement is not consummated, the
Company shall remain responsible for the expenses to be paid or reimbursed by it
pursuant to Section 4 and the respective obligations of the Company and the
Underwriters pursuant to Section 6 shall remain in effect.  If the purchase of
the Securities by the Underwriters is not consummated for any reason other than
solely because of the termination of this Agreement pursuant to Section 7 or the
occurrence of any event specified in clause (iii), (iv) or (v) of Section 5(c),
the Company will reimburse the Underwriters for all out-of-pocket expenses
(including fees and disbursements of counsel) reasonably incurred by them in
connection with the offering of the Securities.

binding upon the Company and such Underwriters as are identified in Terms
Agreements and their respective successors and the officers and directors and
controlling persons referred to in Section 6, and no other person will have any
right or obligation hereunder.

          11.  Applicable Law.  This Agreement and the Terms Agreement shall be

Section 104.   Acts of Holders; Record Dates.
               ----------------------------- 

          (a)  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.

          (b)  The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take 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.

          (c)  The Company may, in the circumstances permitted by the Trust
Indenture Act, fix any day as the record date for the purpose of determining the
Holders of Securities of any series entitled to give, make or take any request,
demand, authorization, direction, notice, consent, waiver or other action, or to
vote on any action, authorized or permitted to be given or taken by Holders of
Securities of such series.  If not set by the Company prior to the first
solicitation of a Holder of Securities of such series by any Person in respect
of any such action, or, in the case of any such vote, prior to such vote, the
record date for any such action or vote shall be the 30th day (or, if later, the
date of the most recent list of Holders required to be provided pursuant to
Section 701) prior to such first solicitation or vote, as the case may be.  With
regard to

                                       11
<PAGE>
 
any record date for action to be taken by the Holders of one or more series of
Securities, only the Holders of Securities of such series on such date (or their
duly designated proxies) shall be entitled to give or take, or vote on, the
relevant action.

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

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

          (f)  Upon receipt by the Trustee of (i) any Notice of Default pursuant
to Section 501; (ii) any notice declaring an acceleration or rescission and
annulment thereof pursuant to Section 502; (iii) any request to institute
proceedings referred to in Section 507(2); or (iv) any direction pursuant to
Section 512 (in the case of any of (i), (ii), (iii) or (iv), a "Notice") from
any Holder or Holders with respect to Securities of a series all or part of
which is represented by a Global Security, a record date shall be established
for determining Holders of Outstanding Securities of such series entitled to
join in such Notice, which record date shall be at the close of business on the
third Business Day following the day the Trustee receives such Notice.  The
Holders on such record date, or their duly designated proxies, and only such
Persons, shall be entitled to join in such Notice, whether or not such Holders
remain Holders after such record date; provided, that unless Holders of at least
                                       --------                                 
the percentage of the principal amount of the Outstanding Securities (the
"Required Principal Amount") of such series required to give such Notice, or
their proxies, shall have joined in such Notice, prior to the day which is 90
days after such record date, such Notice shall automatically and without further
action by any Holder be canceled and of no further effect.  Nothing in this
paragraph shall prevent a Holder, or a proxy of a Holder, from giving (i) after
expiration of such 90-day period, a new Notice identical to a Notice which has
been canceled pursuant to the proviso to the preceding sentence, or (ii) during
any such 90-day period, an additional Notice with respect to any new or
different fact or circumstance permitting the giving of a Notice with respect to
Securities of such series, in either of which events a new record date

                                       12
<PAGE>
 
shall be established pursuant to the provisions of this Section 104(f).  Unless
any Notice specifies that it is given with respect to a lesser principal amount,
the Trustee shall treat the Notice as having been given with respect to the
entire principal amount of Securities held by such Holder.  If a Notice is given
with respect to a principal amount of Securities which exceeds the Required
Principal Amount, no record date shall be established pursuant to this Section
104(f) to determine the Holders entitled to join in such Notice.


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:  One First National
     Plaza, Suite 0126, Chicago, Illinois 60670-0126, 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.
               -------------------------

if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date, and not earlier than the earliest date, prescribed for the
giving of such notice.  In any case where notice to Holders is given by mail,
neither the failure to mail such notice, nor any defect in any notice so mailed,
to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders.  Where this Indenture provides for

                                       13
<PAGE>
 
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 that 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 that 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

Section 109.   Successors and Assigns.
               ---------------------- 

          All covenants and agreements in this Indenture by the Company shall

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

invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

in accordance with the laws of the State of New York.


Section 113.   Legal Holidays.
               -------------- 

          In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwith-standing any other provision of this Indenture or of the
Securities (other than a provision of the Securities of any series 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, provided
that no interest shall accrue for the period from and after such Interest
Payment Date, Redemption Date or Stated Maturity, as the case may be.

     which payment of the principal of and any premium and interest on
     Securities of such series as to which such election is made shall be
     payable, and the periods within which and the terms and conditions upon
     which such election is to be made (or the manner in which such amount shall
     be determined);

            (14)  whether the Securities of the series shall be issued in whole
     or in part in the form of one or more Global Securities and, in such case,
     the Depositary or Depositaries with respect to such Global Security or
     Securities, the form of any legend or legends which shall be borne by any
     such Global Security in addition to or in lieu of that set forth in Section
     205 and the circumstances under which any Global Security may be registered
     for transfer or exchange, or authenticated and delivered, in the name of a
     Person other than such Depositary or its nominee, if other than as set
     forth in Section 305;

            (15)  any other terms of the series (which terms shall not be
     inconsistent with the provisions of this Indenture, except as permitted by
     Section 901(5));

            (16)  if the principal amount payable at the Stated Maturity of any
     Securities of the series will not be determinable as of any one or more
     dates prior to the Stated Maturity, the amount which shall be deemed to be
     the principal amount of such Securities as of any such date for any purpose
     thereunder or hereunder, including the principal amount thereof which shall
     be due and payable upon any Maturity other than the Stated Maturity or
     which shall be deemed to be Outstanding as of any date prior to the Stated
     Maturity (or, in any such case, the manner in which such amount deemed to
     be the principal amount shall be determined);

            (17)  whether the Securities of the series, in whole or any
     specified part, shall be defeasible pursuant to Section 1302 or Section
     1303 or both such Sections and, if other than by a Board Resolution, the

                                       26
<PAGE>
 
     manner in which any election by the Company to defease such Securities
     shall be evidenced;

            (18)  any addition to or change in the Events of Default which
     applies to any Securities of the series and any change in the right of the
     Trustee or the requisite Holders of such Securities to declare the
     principal amount thereof due and payable pursuant to Section 502; and

            (19)  any addition to or change in the covenants set forth in
     Article Ten which applies to Securities of the series.

          All Securities of any one series shall be substantially identical
except as to denomination and except as may otherwise be provided in or pursuant
to the Board Resolution referred to above and (subject to Section 303) set forth
or determined in the manner provided in the Officers' Certificate referred to
above or in any such indenture supplemental hereto.

          If any of the terms of the series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by the Secretary or an Assistant Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.


Section 302.   Denominations.
               ------------- 

          The Securities of each series shall be issuable in registered form
without coupons in such denominations as shall be specified as contemplated by
Section 301.  In the absence of any such provisions with respect to the
Securities of any series, the Securities of such series shall be issuable in
denominations of $1,000 and any integral multiple thereof.


Section 303.   Execution, Authentication, Delivery and Dating.
               ---------------------------------------------- 

          The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its President or one of its Executive or Senior Vice
Presidents, under its corporate seal reproduced thereon attested by its
Secretary or one of its Assistant Secretaries.  The signature of any of these
officers on the Securities may be manual or facsimile.

                                       27
<PAGE>
 
          Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities.  If the
form or terms of the Securities of the series have been established 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,

            (a)  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;

            (b)  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

            (c)  that such Securities, when authenticated and delivered by the
     Trustee and issued by the Company in the manner and subject to any
     conditions specified in such Opinion of Counsel, will constitute valid and
     legally binding obligations of the Company enforceable in accordance with
     their terms, subject to bankruptcy, insolvency, 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

                                       28
<PAGE>
 
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 time
of authentication of each Security of such series if such documents are
delivered at or prior to the authentication upon original issuance of the first
Security of such series to be issued.

          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 and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 309 together
with a written statement (which need not comply with Section 102 and need not be
accompanied by an Opinion of Counsel) stating that such Security has never been
issued and sold by the Company, for all purposes of this Indenture such Security
shall be deemed never to have been authenticated and delivered hereunder and
shall never be entitled to the benefits of this Indenture.


Section 304.   Temporary Securities.
               -------------------- 

          Pending the preparation of definitive Securities of any series, the
Company may execute, and upon 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.

                                       29
<PAGE>
 
          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 aggregate principal amount and tenor.  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 transfer of Securities as herein provided.

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

          At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series, of any authorized denominations and of
a like aggregate principal amount and tenor, 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

                                       30
<PAGE>
 
and deliver, the Securities which the Holder making the exchange is entitled to
receive.

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

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

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

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

          Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any Global Security shall be exchangeable pursuant
to this Section 305 for Securities registered in the names of Persons other than
the Depositary for such series or its nominee if, but only if, (i) such
Depositary notifies the Company that it is unwilling or unable to continue as
Depositary for such Global Security or at any time ceases to be a clearing
agency registered as such under the Exchange Act, (ii) the Company executes and
delivers to the Trustee a Company Order that such Global Security shall be so
exchangeable or (iii) there shall have occurred and be continuing an Event of
Default with respect to the Securities of such series.  Any Global Security that
is exchangeable pursuant to the

                                       31
<PAGE>
 
preceding sentence shall be exchangeable for Securities registered in such names
as such Depositary shall direct.

          Notwithstanding any other provision of this Indenture, a Global
Security may not be transferred except as a whole by the Depositary for such
Global Security to a nominee of such Depositary or by a nominee of such
Depositary to such Depositary or another nominee of such Depositary.


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.

          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

                                       32
<PAGE>
 
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

                                       33
<PAGE>
 
     Defaulted Interest which shall be not more than 15 days and not less than
     10 days prior to the date of the proposed payment and not less than 10 days
     after the receipt by the Trustee of the notice of the proposed payment.
     The Trustee shall promptly notify the Company of such Special Record Date
     and, in the name and at the expense of the Company, shall cause notice of
     the proposed payment of such Defaulted Interest and the Special Record Date
     therefor to be mailed, first-class postage prepaid, to each Holder of
     Securities of such series at his address as it appears in the Security
     Register, not less than 10 days prior to such Special Record Date.  Notice
     of the proposed payment of such Defaulted Interest and the Special Record
     Date therefor having been so mailed, such Defaulted Interest shall be paid
     to the Persons in whose names the Securities of such series (or their
     respective Predecessor Securities) are registered at the close of business
     on such Special Record Date and shall no longer be payable pursuant to the
     following Clause (2).

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

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


Section 308.   Persons Deemed Owners.
               --------------------- 

          Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of, and any premium
and (subject to Section 307) any interest on, such Security and for all other
purposes whatsoever,

                                       34
<PAGE>
 
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.

          No holder of any beneficial interest in any Global Security held on
its behalf by a Depositary shall have any rights under this Indenture with
respect to such Global Security, and such Depositary shall be treated by the
Company, the Trustee and any agent of the Company or the Trustee as the owner of
such Global Security for all purposes whatsoever, except as set forth herein.


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 canceled 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
canceled by the Trustee. No Securities shall be authenticated in lieu of or in
exchange for any Securities canceled as provided in this Section, except as
expressly permitted by this Indenture. All canceled Securities held by the
Trustee shall be destroyed.


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.

          Section 1003) have been delivered to the Trustee for cancellation; or

               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

          Date, as the case may be;

          (2)  the Company has paid or caused to be paid all other sums payable

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

     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 10% in principal amount of the Outstanding Securities of that

     indebtedness for money borrowed by the Company or any Major Constituent
     Bank (including this Indenture), whether such indebtedness now exists or
     shall hereafter be created, which default 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
     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, in any individual instance or in the aggregate (including any
     other indebtedness subject to cross default with respect to payment or
     cross acceleration as a result of such default or acceleration) in the

     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

     consent by the Company or any Major Constituent Bank to the entry of a

     Constituent 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 the Company or any Major Constituent Bank, or the filing

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


Section 502.   Acceleration of Maturity; Rescission and Annulment.
               --------------------------------------------------

          If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series may declare the principal amount (or, if
any of the Securities of that series are Original Issue Discount Securities,
such portion of the principal amount of such Securities as may be specified in
the terms thereof) of all of the Securities of that series to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal amount (or specified
amount) shall become immediately due and payable, except that no such
declaration shall be required upon the occurrence of an Event of Default
specified in Section 501(6) or 501(7) in order for such principal amount (or
specified amount) to 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

                                       40
<PAGE>
 
          (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 any premium 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 Events of Default with respect to Securities of that series,
     other than the non-payment of the principal of Securities of that series
     which have become due solely by such declaration of acceleration, have been
     cured or waived as provided in Section 513.

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


Section 503.   Collection of Indebtedness and Suits for Enforcement by Trustee.
               ---------------------------------------------------------------

          The Company covenants that if

          (1)  default is made in the payment of any 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,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole

                                       41
<PAGE>
 
amount then due and payable on such Securities for principal and any premium and
interest and, to the extent that payment of such interest shall be legally
enforceable, interest on any overdue principal and any premium and on any
overdue interest, at the rate or rates prescribed therefor in such Securities,
and, in addition thereto, such further amount as shall be sufficient to cover
the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

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

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


Section 504.   Trustee May File Proofs of Claim.
               -------------------------------- 

          In case of 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

                                       42
<PAGE>
 
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.


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:  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 Event of Default with respect to the Securities of that
     series;

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

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

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

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

it being understood and intended that no one or more 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.
               --------

          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

                                       44
<PAGE>
 
Section 307) any interest on, such Security on the Stated Maturity or Maturities
expressed in such Security (or, in the case of redemption, on the Redemption
Date) and to institute suit for the enforcement of any such payment, and such
rights shall not be impaired without the consent of such Holder.


Section 509.   Restoration of Rights and Remedies.
               ---------------------------------- 

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


Section 510.   Rights and Remedies Cumulative.
               ------------------------------ 

          Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in the last paragraph
of Section 306, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.


Section 511.   Delay or Omission Not Waiver.
               ---------------------------- 

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

 Section 512.  Control by Holders.
               ------------------ 

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

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

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


Section 513.   Waiver of Past Defaults.
               ----------------------- 

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

          (1)  in the payment of the principal of, or 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.

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Persons entitled to waive any past default
hereunder. If a record date is fixed, the Holders on such record date, or their
duly designated proxies, and only such Persons, shall be entitled to waive any
default hereunder, whether or not such Holders remain Holders after such record
date; provided, that unless such majority in principal amount shall have been
obtained prior to the date which is 90 days after such record date, any such
waiver previously given shall automatically and without further action by any
Holder be canceled and of no further effect.

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 or the Trustee.


Section 515.   Waiver of Stay or Extension Laws.
               -------------------------------- 

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


                                  ARTICLE SIX

                                  The Trustee

Section 601.   Certain Duties and Responsibilities.
               ----------------------------------- 

          The Trustee, prior to the occurrence of an Event of Default and after
the curing or waiving of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically set
forth in this Indenture.  In case an Event of Default has occurred (which has
not been cured or waived) the Trustee shall exercise such of the rights and
powers vested in it by this Indenture, and use the same degree of care and skill
in their exercise, as a prudent person would exercise or use under the
circumstances in the conduct of its own affairs.

          No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent

                                       47
<PAGE>
 
action, its own negligent failure to act or its own wilful misconduct, except
that

          (1)  prior to the occurrence of an Event of Default and after the
     curing or waiving of all such   Events of Default which may have occurred:

               (A)  the duties and obligations of the Trustee shall be
          determined solely by the express provisions of this Indenture, and the
          Trustee shall not be liable except for the performance of such duties
          and obligations as are specifically set forth in this Indenture, and
          no implied covenants or obligations shall be read into this Indenture
          against the Trustee; and

               (B)  in the absence of bad faith on the part of the Trustee, the
          Trustee may conclusively rely, as to the truth of the statements and
          the correctness of the opinions expressed therein, upon any
          certificates or opinions furnished to the Trustee conforming to the
          requirements of this Indenture; but in the case of any such
          certificates or opinions which by any provision hereof are
          specifically required to be furnished to the Trustee, the Trustee
          shall be under a duty to examine the same to determine whether or not
          they conform to the requirements of this Indenture;

          (2)  the Trustee shall not be liable for any error of judgment made in
     good faith by a responsible officer or responsible officers of the Trustee,
     unless it shall be proved that the Trustee was negligent in ascertaining
     the pertinent facts; and

          (3)  the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the direction
     of the holders of not less than a majority in principal amount of the
     Securities of any series at the time Outstanding relating to the time,
     method and place of conducting any proceeding for any remedy available to
     the Trustee, or exercising any trust or power conferred upon the Trustee,
     under this Indenture with respect to the Securities of such series.

          None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any

                                       48
<PAGE>
 
of its rights or powers, if there shall be reasonable ground for believing that
the repayment of such funds or adequate indemnity against such liability is not
reasonably assured to it.

          The provisions of this Section 601 are in furtherance of and are
subject to, Section 315 of the Trust Indenture Act.


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), the Trustee shall not give notice thereof to any Holders until
at least 30 days after the occurrence thereof. For the purpose of this Section,
the term "default" means any event which is, or after notice or lapse of time or
both would become, an Event of Default with respect to Securities of such
series.


Section 603.   Certain Rights of Trustee.
               ------------------------- 

          Subject to Section 601:

          (a)  the Trustee may rely and shall be protected in acting or
     refraining from acting upon any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or

any Securities which are not Global Securities, such Trustee shall have a
Corporate Trust Office in the Borough of Manhattan, The City of New York.  If
such Person publishes reports of condition at least annually, pursuant to law or

                                       52
<PAGE>
 
          (b)  The Trustee may resign at any time with respect to the Securities
of one or more series by giving written notice thereof to the Company.  If the
instrument of acceptance by a successor Trustee required by Section 611 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

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

          (d)  If at any time:

          (1)  the Trustee shall fail to comply with Section 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

          (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

Trustee with respect to all Securities, or (ii) subject to Section 514, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

          (e)  If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of that or those

                                       53
<PAGE>

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

          (f)  The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each

to the Securities of such series and the address of its Corporate Trust Office.


Section 611.   Acceptance of Appointment by Successor.
               -------------------------------------- 

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

                                       54
<PAGE>
 
successor Trustee all the rights, powers and trusts of the retiring Trustee and
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder.

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

          (c)  Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts
referred

                                       55

to in paragraph (a) or (b) of this Section, as the case may be.

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


Section 612.   Merger, Conversion, Consolidation or Succession to Business.
               -----------------------------------------------------------

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


Section 613.   Preferential Collection of Claims Against Company.
               -------------------------------------------------

          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

                                       56
<PAGE>
 
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 mail written notice of
such

                                       57
<PAGE>
 
appointment by first-class mail, postage prepaid, to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve, as
their names and addresses appear in the Security Register.  Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with
like effect as if originally named as an Authenticating Agent.  No successor
Authenticating Agent shall be appointed unless eligible under the provisions of
this Section.

          The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

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

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

                                                           --------  ------- 
that no such supplemental

<PAGE>
 
indenture shall, without the consent of the Holder of each Outstanding Security
affected thereby,

          (1)  change the Stated Maturity of the principal of, or any instalment
     of principal of or interest on, any Security, or reduce the principal
     amount thereof or the rate of interest thereon or any premium payable upon
     the redemption thereof, or reduce the amount of the principal of an
     Original Issue Discount Security that would be due and payable upon a
     declaration of acceleration of the Maturity thereof pursuant to Section
     502, or change any Place of Payment where, or the coin, currency or
     currency unit in which, any Security or any premium or interest thereon is

          (2)  reduce the percentage in principal amount of the Outstanding
     Securities of any series, the consent of whose Holders is required for any

     Indenture, or

          (3)  modify any of the provisions of this Section, Section 513 or
     Section 1010, except to increase any such percentage or to provide that
     certain other provisions of this Indenture cannot be modified or waived
     without the consent of the Holder of each Outstanding Security affected
     thereby; provided, however, that this clause shall not be deemed to require
              --------  -------

     Trustee" and concomitant changes in this Section and Section 1010, or the
     deletion of this proviso, in accordance with the requirements of Sections
     611(b) and 901(8).

A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with respect to such covenant
or other provision, shall be deemed

not to affect the rights under this Indenture of the Holders of Securities of
any other series.

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Persons entitled to consent to any indenture
supplemental hereto.  If a record date is fixed, the Holders on such record
date, or their duly designated proxies, and only such Persons, shall be entitled
to consent to such supplemental indenture, whether or not such Holders remain
Holders after such record date; provided, that unless such consent shall have
become effective by virtue of the requisite percentage having been obtained
prior to the date which is 90 days after such record date, any such consent
previously given shall automatically and without further action by any Holder be
canceled and of no further effect.

          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.

                                  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 presen-
tations, surrenders, notices and demands may be made or

                                       66
<PAGE>
 
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 pur-
poses.  The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.


Section 1003.  Money for Securities Payments to Be Held in Trust.
               -------------------------------------------------

          If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of, and 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 or interest so
becoming due until such sums shall be paid to such Persons or otherwise disposed
of as herein provided and will promptly notify the Trustee of its action or
failure so to act.

          Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, prior to each due date of the principal of, and
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 (i) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (ii) 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

                                       67
<PAGE>
 
the Trustee all sums held in trust by such Paying Agent for payment in respect
of the Securities of such 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, and any premium or
interest on, any Security of any series and remaining unclaimed for two years
after such principal and any 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.


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

                                       68

          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 existence,
rights (charter and statutory) and franchises; provided, however, that the
                                               --------  -------          
Company shall not be required to preserve any such right or franchise if the
Board of Directors shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company and that the loss
thereof is not disadvantageous in any material respect to the Holders.


Section 1006.  Maintenance of Properties.
               -------------------------

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 or any Subsidiary; provided,
                                                                      --------

be paid or discharged any such tax, assessment, charge or claim whose amount,

     permit a Major Constituent Bank (or a Subsidiary owning Voting Stock of a
     Major Constituent Bank) to issue any shares of, or securities convertible
     into or options, warrants or rights to subscribe for or purchase shares of,
     such Voting Stock if, in each case, after giving effect to any such
     transaction and to the issuance of the maximum number of shares of Voting
     Stock of such Major Constituent Bank (or Subsidiary) issuable upon the
     exercise of all such convertible securities, options, warrants or rights,
     the Major Constituent Bank would cease to be a Controlled Subsidiary, or

     Stock of a Major Constituent Bank) to

               (i)  merge or consolidate with or into any other corporation,
          unless the surviving corporation is, or upon consummation of the
          merger or consolidation will become, a Controlled Subsidiary; or

               (ii)  lease, sell or transfer all or substantially all of its

          or a Person that, upon such lease, sale or transfer, will become a
          Controlled Subsidiary.

          Notwithstanding the foregoing, any such sale or other disposition of
securities, any such merger or consolidation or any such lease, sale or
transfer of properties and assets shall not be prohibited (i) if required by any
law or any rule, regulation or order of any governmental agency or authority,
(ii) if required as a condition imposed by any law or any rule, regulation or
order of any governmental agency or authority to the acquisition by the Company,

giving effect to such other prohibited transaction and such acquisition, (A)
such Person will be a Controlled Subsidiary and (B) the Consolidated Banking
Assets of the Company will be at least equal to the Consolidated Banking Assets
of the Company prior thereto, or (iii) if the proceeds from such otherwise
prohibited transaction are within 180 days after such transaction, or such
longer period of time as may be necessary to obtain regulatory approval in
connection therewith, invested by the Company, pursuant to an understanding or

into or options, warrants or rights to subscribe for or purchase shares of,
Voting Stock of a Major Constituent Bank now or hereafter owned by the Company,
directly or indirectly, without making effective provision whereby any
Securities shall be equally and ratably secured with any and all such
indebtedness if, treating such pledge, encumbrance or lien as a transfer of the
shares of, or securities convertible into or options, warrants or rights to
subscribe for or purchase shares of, Voting Stock subject thereto to the secured
party and after giving effect to the issuance of the maximum number of shares of
Voting Stock of such Major Constituent Bank issuable upon the exercise of all
such convertible securities, options, warrants or rights, the Major Constituent

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.

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Persons entitled to waive any such term,
provision or condition.  If a record date is fixed, the Holders on such record
date, or their duly designated proxies, and only such Persons, shall be entitled
to waive any such term, provision or condition hereunder, whether or not such
Holders remain Holders after such record date; provided, that unless the Holders
of at least 66 2/3% in principal amount of the Outstanding Securities of such
series shall have waived such term, provision or condition prior to the date
which is 90 days after such record date, any such waiver previously given shall
automatically and without further action by any Holder be canceled and of no
further 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 Securities of any series)
in accordance with this Article.


Section 1102.  Election to Redeem; Notice to Trustee.
               ------------------------------------- 

          The election of the Company to redeem any Securities shall be
evidenced by a Board Resolution.  In case of any redemption at the election of
the Company of less than all the Securities of any series, the Company shall, at
least 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

                                       72
<PAGE>
 
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 of 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 portions (equal to the minimum authorized denomination for
Securities of that series or any integral multiple thereof) of the principal
amount of Securities of such series of a denomination larger than the minimum
authorized denomination for Securities of that series.  If less than all of the
Securities of such series and of a specified tenor are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series 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 and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed.

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


Section 1104.  Notice of Redemption.
               -------------------- 

          Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 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:

                                       73
<PAGE>
 
          (1)  the Redemption Date,

          (2)  the Redemption Price (and interest, if any),

          (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 Securities,
     the principal amounts) of the particular Securities to be redeemed,

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

          (5)  the place or places where such Securities are to be surrendered
     for payment of the Redemption Price, and

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

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


Section 1105.  Deposit of Redemption Price.
               --------------------------- 

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


Section 1106.  Securities Payable on Redemption Date.
               ------------------------------------- 

          Notice of redemption having been given as aforesaid, the Securities
so to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest.  Upon surrender of any
such Security for redemp-

                                       74
<PAGE>
 
tion 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 shall be payable to the Holders of such Securities, or one or
more Predecessor Securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of Section
307.

          If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and 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; provided, that if a Global Security is as
                             --------                                 
surrendered, such new Security so issued shall be a new Global Security in a
denomination equal to the unredeemed portion of the principal of the Global
Security so surrendered.

                                 Sinking Funds

Section 1201.  Applicability of Article.
               ------------------------ 

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

                                       75
<PAGE>
 
          The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment", and any payment in excess of such minimum amount provided for by
the terms of Securities of any series is herein referred to as an "optional
sinking fund payment".  If provided for by the terms of Securities of any
series, the cash amount of any sinking fund payment may be subject to reduction
as provided in Section 1202.  Each sinking fund payment shall be applied to the
redemption of Securities of any series as provided for by the terms of
Securities of such series.

Section 1202.  Satisfaction of Sinking Fund Payments with Securities.
               -----------------------------------------------------

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


Section 1203.  Redemption of Securities for Sinking Fund.
               ----------------------------------------- 

          Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 1202 and will also deliver to the Trustee any Securities to
be so delivered.  Not less than 30 days before each such sinking fund payment
date the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 1103 and cause

                                       76
<PAGE>
 
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 1105, 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
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

                                       77
<PAGE>
 
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, 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 Article applicable to it) as trust funds in trust for
     the purpose of making the following payments, specifically pledged as
     security for, and dedicated solely to, the benefits of the Holders of such
     Securities, (A) money in an amount, or (B) U.S.

                                       78
<PAGE>
 
     Government Obligations which through the scheduled payment of principal and
     interest in respect thereof in accordance with their terms will provide,
     not later than one day before the due date of any payment, money in an
     amount, or (C) a combination thereof, 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.

          (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)
     the Company has received from, or there has been published by, the Internal
     Revenue Service a ruling or (B) since the date of this instrument, there
     has been a change in the applicable Federal income tax law, in either case
     (A) or (B) to the effect that, and based thereon such opinion shall confirm
     that, the

                                       79
<PAGE>
 
     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.

          (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, an Event of 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 such deposit
     (it being understood that this condition shall not be deemed satisfied
     until after such 90th day).

          (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

                                       80
<PAGE>
 
     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 and U.S. 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 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 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.
                    ------------- 

               Anything herein to the contrary notwithstanding, if and to the
     extent the deposited money or U.S. Government Obligations (or the proceeds
     thereof) either (i) cannot be applied by the Trustee in accordance with
     Section 1305 because of a court order or (ii) are for any reason
     insufficient in amount, then the Company's obligations to pay principal of
     (and premium, if any) and interest on the Securities of such series shall
     be reinstated as though no deposit had occurred pursuant to this Article
     Thirteen until such time as the Trustee or Paying Agent is permitted to
     apply all such money in accordance with Section 1305; provided, however,
                                                           --------  ------- 
     that if the Company makes any payment of principal of (and premium, if any)
     and interest on any such Security following the reinstatement of its
     obligations, the Company shall be subrogated to the rights of the Holders
     of such Securities to receive such payment from the money held by the
     Trustee or the Paying Agent.  In any case specified in clause (i), the
     Company's interest in the deposited money and U.S. Government Obligations
     (and proceeds thereof) shall be reinstated to the extent the Company's
     payment obligations are reinstated.

principal thereof that would be due and payable as of the date of such

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 establishes

such Securities and that the pledgee is not the Company or any other obligor

Section 102.   Compliance Certificates and Opinions.
               ------------------------------------ 

          Except as otherwise expressly provided by the Indenture, upon any
application or request by the Company to the Trustee to take any action under
any provision of this Indenture, the Company shall furnish to the Trustee such
certificates and opinions as may be required under the Trust Indenture Act.

     opinion has read such covenant or condition and the definitions herein

     express an informed opinion as to whether or not such covenant or condition

          In any case where several matters are required to be certified by, or

Section 104.   Acts of Holders; Record Dates.
               ----------------------------- 

          (a)  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.

          (b)  The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a

                                       12
<PAGE>
 
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.

          (c)  The Company may, in the circumstances permitted by the Trust
Indenture Act, fix any day as the record date for the purpose of determining the
Holders of Securities of any series entitled to give, make or take any request,
demand, authorization, direction, notice, consent, waiver or other action, or to
vote on any action, authorized or permitted to be given or taken by Holders of
Securities of such series.  If not set by the Company prior to the first
solicitation of a Holder of Securities of such series by any Person in respect
of any such action, or, in the case of any such vote, prior to such vote, the
record date for any such action or vote shall be the 30th day (or, if later, the
date of the most recent list of Holders required to be provided pursuant to
Section 701) prior to such first solicitation or vote, as the case may be.  With
regard to any record date for action to be taken by the Holders of one or more
series of Securities, only the Holders of Securities of such series on such date
(or their duly designated proxies) shall be entitled to give or take, or vote
on, the relevant action.

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

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

          (f)  Upon receipt by the Trustee of (i) any Notice of Default pursuant
to Section 503; (ii) any notice declaring an acceleration or rescission and
annulment thereof pursuant to Section 502; (iii) any request to institute
proceedings referred to in Section 507(2) or

                                       13
<PAGE>
 
(iv) any direction pursuant to Section 512 (in the case of any of (i), (ii),
(iii) or (iv), a "Notice") from any Holder or Holders with respect to Securities
of a series all or part of which is represented by a Global Security, a record
date shall be established for determining Holders of Outstanding Securities of
such series entitled to join in such Notice, which record date shall be at the
close of business on the third Business Day following the day the Trustee
receives such Notice.  The Holders on such record date, or their duly designated
proxies, and only such Persons, shall be entitled to join in such Notice,
whether or not such Holders remain Holders after such record date; provided,
                                                                   -------- 
that unless Holders of at least the percentage of the principal amount of the
Outstanding Securities (the "Required Principal Amount") of such series required
to give such Notice, or their proxies, shall have joined in such Notice, prior
to the day which is 90 days after such record date, such Notice shall
automatically and without further action by any Holder be canceled and of no
further effect.  Nothing in this paragraph shall prevent a Holder, or a proxy of
a Holder, from giving (i) after expiration of such 90-day period, a new Notice
identical to a Notice which has been canceled pursuant to the proviso to the
preceding sentence, or (ii) during any such 90-day period, an additional Notice
with respect to any new or different fact or circumstance permitting the giving
of a Notice with respect to Securities of such series, in either of which events
a new record date shall be established pursuant to the provisions of this
Section 104(f).  Unless any Notice specifies that it is given with respect to a
lesser principal amount, the Trustee shall treat the Notice as having been given
with respect to the entire principal amount of Securities held by such Holder.
If a Notice is given with respect to a principal amount of Securities which
exceeds the Required Principal Amount, no record date shall be established
pursuant to this Section 104(f) to determine the Holders entitled to join in
such Notice.


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

                                       14
<PAGE>
 
     Trust Office:  One First National Plaza, Suite 0126, Chicago, Illinois
     60670-0126, 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, and not earlier than the earliest date, prescribed for the
giving of such notice.  In any case where notice to Holders is given by mail,
neither the failure to mail such notice, nor any defect in any notice so mailed,
to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders.  Where this Indenture provides for notice in any
manner, such notice may be waived in writing by the Person entitled to receive
such notice, either before or after the event, and such waiver shall be the
equivalent of such notice.  Waivers of notice by Holders shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

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


Section 107.   Conflict with Trust Indenture Act.
               --------------------------------- 

          If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that 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

                                       15
<PAGE>
 
provision of the Trust Indenture Act that 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

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

          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.
               ---------------------

shall give to any Person, other than the parties hereto and their successors
hereunder, the holders of Senior Indebtedness, the Holders and, subject to
Section 907, Entitled Persons in respect of Other Financial Obligations, any
benefit or any legal or equitable right, remedy or claim under this Indenture.

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 the Securities of any series 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, provided
that no interest shall accrue for the period from and after such Interest
Payment Date, Redemption Date or Stated Maturity, as the case may be.

regarding payments to Entitled Persons in respect of Other Financial
Obligations.  Each Holder of this Security, by accepting the same, agrees to be

appropriate to acknowledge or effectuate the subordination of this Security and

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

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.

therein set forth, the transfer of this Security is registerable in the Security

     provisions, including a different definition of the terms "Senior
     Indebtedness," "Entitled Persons," "Existing Subordinated Indebtedness," or
     "Other Financial Obligations," shall apply to the Securities of such
     series; and

            (20)  any other terms of the series (which terms shall not be
     inconsistent with the provisions of this Indenture, except as permitted by
     Section 901(5)).

          All Securities of any one series shall be substantially identical
except as to denomination and except as may otherwise be provided in or pursuant
to the Board Resolution referred to above and (subject to Section 303) set forth
or determined in the manner provided in the Officers' Certificate referred to
above or in any such indenture supplemental hereto.

          If any of the terms of the series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by the Secretary or an Assistant Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.

          The Securities shall be subordinated in right of payment to Senior
Indebtedness as provided in Article Thirteen.  The indebtedness evidenced by the
Securities shall not be superior in right of payment to and shall rank pari
                                                                       ----

Section 302.   Denominations.
               ------------- 

          The Securities of each series shall be issuable in registered form
without coupons in such denominations as shall be specified as contemplated by
Section 301.  In the absence of any such provisions with respect to the
Securities of any series, the Securities of such series

                                       30
<PAGE>
 
shall be issuable in denominations of $1,000 and any integral multiple thereof.


Section 303.   Execution, Authentication, Delivery and Dating.
               ----------------------------------------------

          The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its President or one of its Executive or Senior Vice
Presidents, under its corporate seal reproduced thereon attested by its
Secretary or one of its Assistant Secretaries.  The signature of any of these
officers on the Securities may be manual or facsimile.

          Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities.  If the
form or terms of the Securities of the series have been established 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,

            (a)  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;

            (b)  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

                                       31
<PAGE>
 
            (c) that such Securities, when authenticated and delivered by the
     Trustee and issued by the Company in the manner and subject to any
     conditions specified in such Opinion of Counsel, will constitute valid and
     legally binding obligations of the Company enforceable in accordance with
     their terms, subject to bankruptcy, insolvency, 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 time
of authentication of each Security of such series if such documents are
delivered at or prior to the authentication upon original issuance of the first
Security of such series to be issued.

          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 and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 309 together
with a written statement (which need not comply with Section 102 and need not be
accompanied by an Opinion of Counsel) stating that such Security has never been
issued and sold by the Company, for all purposes of this Indenture such Security
shall be deemed never to have been authenticated and delivered hereunder and
shall never be entitled to the benefits of this Indenture.

Section 304.   Temporary Securities.
               -------------------- 

          Pending the preparation of definitive Securities of any series, the
Company may execute, and upon 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 aggregate principal amount and tenor.  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 transfer of Securities as herein provided.

                                       33
<PAGE>
 
          Upon surrender for registration of transfer of any Security of any
series at the office or agency in a Place of Payment for that series, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
the same series, of any authorized denominations and of a like aggregate
principal amount and tenor and with a like Maturity.

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

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

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

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

          The Company shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section 1103 and ending
at the close of business on the day of such mailing, or (ii) to register the
transfer of or exchange any Security so selected for

                                       34
<PAGE>
 
redemption in whole or in part, except the unredeemed portion of any Security
being redeemed in part.

          Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any Global Security shall be exchangeable pursuant
to this Section 305 for Securities registered in the names of Persons other than
the Depositary for such series or its nominee if, but only if, (i) such
Depositary notifies the Company that it is unwilling or unable to continue as
Depositary for such Global Security or at any time ceases to be a clearing
agency registered as such under the Exchange Act, (ii) the Company executes and
delivers to the Trustee a Company Order that such Global Security shall be so
exchangeable or (iii) there shall have occurred and be continuing a Default, or
an event which with notice, lapse of time or both would be a Default, with
respect to the Securities of such series.  Any Global Security that is
exchangeable pursuant to the preceding sentence shall be exchangeable for
Securities registered in such names as such Depositary shall direct.

          Notwithstanding any other provision of this Indenture, a Global
Security may not be transferred except as a whole by the Depositary for such
Global Security to a nominee of such Depositary or by a nominee of such
Depositary to such Depositary or another nominee of such Depositary.


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.

                                       35
<PAGE>
 
          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.

          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

                                       36
<PAGE>
 
     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 mailed, first-class postage prepaid, to each Holder of Securities of
     such series at his address as it appears in the Security Register, not less
     than 10 days prior to such Special Record Date. Notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor
     having been so mailed, such Defaulted Interest shall be paid to the Persons
     in whose names the Securities of such series (or their respective
     Predecessor Securities) are registered at the close of business on such
     Special Record Date and shall no longer be payable pursuant to the
     following Clause (2).

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

                                       37
<PAGE>
 
          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.

          No holder of any beneficial interest in any Global Security held on
its behalf by a Depositary shall have any rights under this Indenture with
respect to such Global Security, and such Depositary shall be treated by the
Company, the Trustee and any agent of the Company or the Trustee as the owner of
such Global Security for all purposes whatsoever, except as set forth herein.


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 canceled 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
canceled by the Trustee. No Securities shall be authenticated in lieu of or in
exchange for any Securities canceled as provided in this Section, except as
expressly permitted by this Indenture. All canceled Securities held by the
Trustee shall be destroyed.

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.

     admission by the Company 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.


Section 502.   Acceleration of Maturity; Rescission and Annulment.
               --------------------------------------------------

          If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series may declare the principal amount (or, if
any of the Securities of that series are Original Issue Discount Securities,
such portion of the principal amount of such Securities as may be specified in
the terms thereof) of all of the Securities of that series to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal amount (or specified
amount) shall become immediately due and payable, except that no such
declaration shall be required upon the occurrence of an Event of Default
specified in Section 501(1) and 501(2) in order for such principal amount (or
specified amount) to 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 any premium 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,

                                       42
<PAGE>
 
               (C) to the extent that payment of such interest is lawful,
          interest upon overdue interest at the rate or rates prescribed
          therefor in such Securities, and

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

     and

          (2)  all Events of Default with respect to Securities of that series,
     other than the non-payment of the principal of Securities of that series
     which have become due solely by such declaration of acceleration, have been
     cured or waived as provided in Section 513.

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


Section 503.   Collection of Indebtedness and Suits for Enforcement by Trustee.
               ---------------------------------------------------------------

          The Company covenants that if

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

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, (including any sinking fund payment or analogous
obligations) and any premium and interest and, to the extent that payment of
such interest shall be legally enforceable, interest on any overdue principal
and any premium 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

                                       43
<PAGE>
 
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

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

          (A)  an Event of Default with respect to that series specified in
     Section 501; or

          (B)  the events referred to in subsections 503(1) through (3) above;
     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 performance or whose breach is elsewhere in this Section
     specifically dealt with or which has expressly been included in this
     Indenture solely for the benefit of series of Securities other than that
     series), and continuance of such default or breach for a period of 60 days
     after there has been given, by registered or certified mail, to the Company
     by the Trustee or to the Company and the Trustee by the Holders of at least
     10% 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)  a default under any bond, debenture, note or other evidence of
     indebtedness for money borrowed by the Company or any Major Constituent
     Bank (including a default with respect to Securities of any series other

                                       44

     than that series) or under any mortgage, indenture or instrument under
     which there may be issued or by which there may be secured or evidenced any
     indebtedness for money borrowed by the Company or any Major Constituent
     Bank (including this Indenture), whether such indebtedness now exists or
     shall hereafter be created, which default 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
     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, in any individual instance or in the aggregate (including any
     other indebtedness subject to cross default with respect to payment or
     cross acceleration as a result of such default or acceleration) in the
     principal amount in excess of $3,000,000, without such indebtedness having
     been discharged, or such acceleration having been rescinded or annulled,
     within a period of 10 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 and
     stating that such notice is a "Notice of Default" hereunder; provided,
                                                                  -------- 
     however, that, subject to 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

          (E)  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.


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 Thirteen, 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;

          (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

                                       47
<PAGE>
 
          (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.
               -------- 

          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) any interest on, such Security on the Stated Maturity or Maturities
expressed in such Security (or, in the case of redemption, on the Redemption
Date) and to institute suit for the enforcement of any such payment, and such
rights shall not be impaired without the consent of such Holder.


Section 509.   Restoration of Rights and Remedies.
               ---------------------------------- 

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


Section 510.   Rights and Remedies Cumulative.
               ------------------------------ 

          Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in the last paragraph
of Section 306, no

                                       48
<PAGE>
 
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.


Section 511.   Delay or Omission Not Waiver.
               -----------------------------

          No delay or omission of the Trustee or of any Holder of any Securities
to exercise any right or remedy accruing upon any 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

                                       49
<PAGE>
 
          (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.

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Persons entitled to waive any past default
hereunder. If a record date is fixed, the Holders on such record date, or their
duly designated proxies, and only such Persons, shall be entitled to waive any
default hereunder, whether or not such Holders remain Holders after such record
date; provided, that unless such majority in principal amount shall have been
obtained prior to the date which is 90 days after such record date, any such
waiver previously given shall automatically and without further action by any
Holder be canceled and of no further effect.


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 or the Trustee.


Section 515.   Waiver of Stay or Extension Laws.
               -------------------------------- 

          The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the

                                       50
<PAGE>
 
execution of any power herein granted to the Trustee, but will suffer and permit
the execution of every such power as though no such law had been enacted.

                                  The Trustee

Section 601.   Certain Duties and Responsibilities.
               ----------------------------------- 

          The Trustee, prior to the occurrence of a Default and after the curing
or waiving of all Defaults which may have occurred, undertakes to perform such
duties and only such duties as are specifically set forth in this Indenture.  In
case a Default has occurred (which has not been cured or waived) the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in their exercise, as a prudent person
would exercise or use under the circumstances in the conduct of its own affairs.

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

          (1)  prior to the occurrence of a Default and after the curing or
     waiving of all such  Defaults which may have occurred:

               (A)  the duties and obligations of the Trustee shall be
          determined solely by the express provisions of this Indenture, and the
          Trustee shall not be liable except for the performance of such duties
          and obligations as are specifically set forth in this Indenture, and
          no implied covenants or obligations shall be read into this Indenture
          against the Trustee; and

               (B)  in the absence of bad faith on the part of the Trustee, the
          Trustee may conclusively rely, as to the truth of the statements and
          the correctness of the opinions expressed therein, upon any
          certificates or opinions furnished to the Trustee conforming to the
          requirements of this Indenture; but in the case of any such
          certificates or opinions which by any provision hereof are
          specifically required to be furnished to the Trustee, the Trustee
          shall be under a duty to examine the same to determine whether or not

                                       51
<PAGE>
 
          they conform to the requirements of this Indenture;

          (2)  the Trustee shall not be liable for any error of judgment made in
     good faith by a responsible officer or responsible officers of the Trustee,
     unless it shall be proved that the Trustee was negligent in ascertaining
     the pertinent facts; and

          (3)  the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the direction
     of the Holders of not less than a majority in principal amount of the
     Securities of any series at the time Outstanding relating to the time,
     method and place of conducting any proceeding for any remedy available to
     the Trustee, or exercising any trust or power conferred upon the Trustee,
     under this Indenture with respect to the Securities of such series.

          None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there shall be reasonable ground for believing that the
repayment of such funds or adequate indemnity against such liability is not
reasonably assured to it.

          The provisions of this Section 601 are in furtherance of and are
subject to, Section 315 of the Trust Indenture Act.


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 503(C), the Trustee shall not give notice thereof to any Holders until
at least 30 days after the occurrence thereof. For the purpose of this Section,
the term "default" means any event which is, or after notice or lapse of time or
both would become, a Default with respect to Securities of such series.

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

          Subject to Section 601:

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

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

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

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

Section 610.   Resignation and Removal; Appointment of Successor.

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

          (b)  The Trustee may resign at any time with respect to the Securities
of one or more series by giving written notice thereof to the Company.  If the
instrument of acceptance by a successor Trustee required by Section 611 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

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

          (d)  If at any time:

          (1)  the Trustee shall fail to comply with Section 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

                                       56
<PAGE>
 
          (2)  the Trustee shall cease to be eligible under Section 609 and
     shall fail to resign after written request therefor by the Company or by
     any such Holder, or

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

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

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

                                       57
<PAGE>

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.
               -------------------------------------- 

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

          (b)  In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the 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

                                       58
<PAGE>
 
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates.

          (c)  Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts
referred to in paragraph (a) or (b) of this Section, as the case may be.

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


Section 612.   Merger, Conversion, Consolidation or Succession to Business.
               -----------------------------------------------------------

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, conver-

                                       59

sion 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 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

                                       60
<PAGE>
 
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

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

          An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company.  Upon receiving such a notice
of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders of
Securities of the series with respect to which such Authenticating Agent will
serve, as their names and addresses appear in the Security Register.  Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the 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 Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

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

                                       61

referred to in the within-mentioned Indenture.

     indenture and entitled to the benefit of such provision nor (B) modify the

Section 902.   Supplemental Indentures with Consent of Holders.
               -----------------------------------------------

          With the consent of the Holders of not less than 66 2/3% in principal
amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company, when authorized by a Board Resolution, and the Trustee may
enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the rights of the
Holders of Securities of such series under this Indenture; provided, however,
                                                           --------  ------- 
that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Security affected thereby,

          (1)  change the Stated Maturity of the principal of, or any instalment
     of principal of or interest on, any Security, or reduce the principal
     amount thereof or the rate of interest thereon or any premium payable upon
     the redemption thereof, or reduce the amount of the principal of an
     Original Issue Discount Security that would be due and payable upon a
     declaration of acceleration of the Maturity thereof pursuant to Section
     502, or change any Place of Payment where, or the coin, currency or
     currency unit 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

          (2)  reduce the percentage in principal amount of the Outstanding
     Securities of any series, the consent of whose Holders is required for any
     such supplemental indenture, or the consent of whose Holders is required

<PAGE>
 
          (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
              --------  -------

     Trustee" and concomitant changes in this Section and Section 1008, or the
     deletion of this proviso, in accordance with the requirements of Sections
     611(b) and 901(8).

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

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Persons entitled to consent to any indenture
supplemental hereto.  If a record date is fixed, the Holders on such record
date, or their duly designated proxies, and only such Persons, shall be entitled
to consent to such supplemental indenture, whether or not such Holders remain
Holders after such record date; provided, that unless such consent shall have
become effective by virtue of the requisite percentage having been obtained
prior to the date which is 90 days after such record date, any such consent
previously given shall automatically and without further action by any Holder be
cancelled and of no further effect.

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


Section 903.   Execution of Supplemental Indentures.
               ------------------------------------ 

          In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 601) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such

                                       68
<PAGE>
 
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 authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and shall if required by
the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture.  If the Company shall so determine,
new Securities of any series so modified as to conform, in the opinion of the
Trustee and the Company, to any such supplemental indenture may be prepared and
executed by the Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities of such series.


Section 907.   Subordination Unimpaired.
               ------------------------

          No provision in any supplemental indenture that affects the superior
position of the holders of Senior Indebtedness shall be effective against any
holder of Senior Indebtedness, unless such holder shall have consented thereto.
Notwithstanding any provision in this Indenture or otherwise, the rights of
Entitled Persons in respect of Other Financial Obligations under this Indenture
and otherwise in respect of the Securities or any series of the Securities may,
at any time and from time to time, be

                                       69

                                   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 presen-
tations, 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, and 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 or interest so
becoming due until such sums shall be paid to such Persons or otherwise disposed
of as herein provided and will promptly notify the Trustee of its action or
failure so to act.

          Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, prior to each due date of the principal of, and
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 (i) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (ii) 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 such 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, and any premium or
interest on, any

                                       71
<PAGE>
 
Security of any series and remaining unclaimed for two years after such
principal and any 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.


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.


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 existence,
rights (charter and statutory) and franchises; provided, however, that the
                                               --------  -------          
Company shall not be required to preserve any such right or franchise if the
Board of Directors shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company and that the loss
thereof is not disadvantageous in any material respect to the Holders.

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 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.


Section 1008.  Waiver of Certain Covenants.
               --------------------------- 

          The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Sections 1006 to 1007, inclusive, with
respect to the Securities of any series if before the time for such compliance
the Holders of at least 66 2/3% 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

force and effect.

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Persons entitled to waive any such term,
provision or condition.  If a record date is fixed, the Holders on such record
date, or their duly designated proxies, and only such Persons, shall be entitled
to waive any such term, provision or condition hereunder, whether or not such
Holders remain Holders after such record date; provided, that unless the Holders
of at least 66 2/3% in principal amount of the Outstanding Securities of such
series shall have waived such term, provision or condition prior to the date
which is 90 days after such record date, any such waiver previously given shall
automatically and without further action by any Holder be canceled and of no
further effect.

in accordance with this Article.


Section 1102.  Election to Redeem; Notice to Trustee.
               ------------------------------------- 

          The election of the Company to redeem any Securities shall be
evidenced by a Board Resolution.  In case of any redemption at the election of
the Company of less than all the Securities of any series, the Company shall, at
least 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 of 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 portions (equal to the minimum authorized denomination for
Securities of that series or any integral multiple thereof) of the principal
amount of Securities of such series of a denomination larger than the minimum
authorized denomination for Securities of that series.  If less than all of the
Securities of such series and of a specified tenor are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series 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 and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed.

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


Section 1104.  Notice of Redemption.
               -------------------- 

          Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 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 (and interest, if any),

                                       75
<PAGE>
 
          (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 Securities,
     the principal amounts) of the particular Securities to be redeemed,

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

          (5)  the place or places where such Securities are to be surrendered
     for payment of the Redemption Price, and

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

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


Section 1105.  Deposit of Redemption Price.
               --------------------------- 

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


Section 1106.  Securities Payable on Redemption Date.
               ------------------------------------- 

          Notice of redemption having been given as aforesaid, the Securities
so to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest.  Upon surrender of any
such Security for redemption in accordance with said notice, such Security
shall be paid by the Company at the Redemption Price, together with accrued
interest to the Redemption Date; provided, however, that, unless otherwise

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

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

Section 1201.  Applicability of Article.
               ------------------------ 

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

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

                                       77
<PAGE>
 
referred to as an "optional sinking fund payment".  If provided for by the terms
of Securities of any series, the cash amount of any sinking fund payment may be
subject to reduction as provided in Section 1202.  Each sinking fund payment
shall be applied to the redemption of Securities of any series as provided for
by the terms of Securities of such series.


Section 1202.  Satisfaction of Sinking Fund Payments with Securities.
               -----------------------------------------------------

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


Section 1203.  Redemption of Securities for Sinking Fund.
               ----------------------------------------- 

          Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 1202 and will also deliver to the Trustee any Securities to
be so delivered.  Not less than 30 days before each such sinking fund payment
date the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 1103 and cause notice of
the redemption thereof to be given in the name of and at the expense of the
Company in the manner provided in Section 1104.  Such notice having been duly
given, the

                                       78
<PAGE>
 
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1105, 1106 and 1107.


                                ARTICLE THIRTEEN

Section 1301.  Securities Subordinate to Senior Indebtedness.
               ---------------------------------------------

          The subordination provisions in this Article Thirteen shall apply to
the Securities of any series to the extent established or determined with
respect to the Securities of such series pursuant to Section 301.

          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 subject to Sections
1402 and 1403, 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.

Section 1302.  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
solvency 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, which may be
payable or deliverable

                                       79
<PAGE>
 
in respect of the Securities in any such case, proceeding, dissolution,
liquidation or other winding up or event.

          In the event that, notwithstanding the foregoing provisions of this
Section, 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, 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 1303. 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 the Senior
Indebtedness shall be entitled to receive payment in full of all amounts due on
or in respect of such 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 of (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) principal of (or premium, if any)
or interest on the securities or on account of the purchase or other acquisition
of Securities.

          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 1302 would be applicable.


Section 1304.  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 (b) in
the event any judicial proceeding shall be pending with respect to any such
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.

          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

                                       81
<PAGE>
 
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 1302 would be applicable.


Section 1305.  Payment Permitted If No Default.
               ------------------------------- 

          Nothing contained in this Article or elsewhere in this Indenture or in
any of the Securities shall prevent (a) the Company, at any time except during
the pendency of any case, 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 1302 or under the conditions
described in Section 1303 or 1304, from making payments at any time of principal
of or interest on the Securities, or (b) the application by the Trustee or any
Paying Agent of any moneys deposited with it hereunder to the payment of or on
account of the principal of (or premium, if any) or interest on the Securities
and the retention by the Holders of any moneys so received if, at the time of
such payment, the Trustee or any such Paying Agent did not have knowledge that
such payment would have been prohibited by the provisions of this Article.


Section 1306.  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 (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

                                       82
<PAGE>
 
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 1307.  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
1315, the holders of Existing Subordinated Indebtedness and 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 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 the rights under
Section 1315 of 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; (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 of Existing Subordinated Indebtedness; 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 1315 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 1308.  Trustee to Effectuate Subordination and Payment Provisions.
               ----------------------------------------------------------

          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

                                       83
<PAGE>
 
effectuate the subordination and payment provisions provided in this Article and
appoints the Trustee his attorney-in-fact for any and all such purposes.


Section 1309.  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 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, 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 otherwise amend or supplement in any manner
Senior Indebtedness or any instrument evidencing the same or any agreement under
which Senior Indebtedness is outstanding; (ii) sell, exchange, release or
otherwise deal with any property pledged, mortgaged or otherwise securing Senior
Indebtedness; (iii) release any Person liable in any manner for the collection
of Senior Indebtedness; and (iv) exercise or refrain from exercising any rights
against the Company and any other Person.


Section 1310.  Notice to Trustee; Trustee Not Charged with Knowledge of
               --------------------------------------------------------
               Prohibition.
               -----------

          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 or
distribution 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 or distribution to or by the Trustee in
respect of the Securities, unless and until the

                                       84
<PAGE>
 
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 shall be entitled in all respects to assume that no
such facts exist.

          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 or distribution to
such Person pending judicial determination as to the right of such Person to
receive such payment.


Section 1311.  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 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 the Senior Indebtedness and
other indebtedness of the Company and the Entitled Persons in respect of Other
Financial Obligations, the amount thereof or payable

                                       85

thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article.


Section 1312.  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 1313.  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 1314.  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,
                                                                 --------

any Affiliate of the Company if it or such Affiliate acts as Paying Agent.


Section 1315.  Securities to Rank Pari Passu with Existing Subordinated
               --------------------------------------------------------
               Indebtedness; Payment of Proceeds in Certain Cases.
               --------------------------------------------------

          (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 shall rank pari passu in right of payment with 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 1302, 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 1302,
Section 1306 and the respective corresponding provisions of each indenture or
other instrument or document establishing or governing the terms of any Existing
Subordinated Indebtedness on such pro rata basis, any amount of cash, property
                                  --- ----                                    
or securities shall be available for payment or distribution in respect of the
Securities ("Excess Proceeds"), and any 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, 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 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 1302, 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).

          (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 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 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

                                       88
<PAGE>
 
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 (1) the holders
of Senior Indebtedness, (2) the holders of Existing Subordinated Indebtedness or
(3) other creditors of the Company other than Entitled Persons in respect of
Other Financial Obligations.


                                ARTICLE FOURTEEN

                       Defeasance and Covenant Defeasance

Section 1401.  Company's Option to Effect Defeasance or Covenant Defeasance.
               ------------------------------------------------------------

          The Company may elect, at its option at any time, to have Section 1402
or Section 1403 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 1402 or 1403, 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 1402.  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 Thirteen 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 1404 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 1404 and as more fully
set forth in such Section, payments in respect of the principal of and

                                       89
<PAGE>
 
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 1403 applied to such Securities.


Section 1403.  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
and 1007, and any covenants provided pursuant to Section 301(17), 901(2) or
901(7) for the benefit of the Holders of such Securities, (2) the occurrence of
any event specified in Sections 503(C) (with respect to any of Sections 1006 and
1007, and any such covenants provided pursuant to Section 301(17), 901(2) or
901(7)), 503(D) shall be deemed not to be or result in a Default and (3) the
provisions of Article Thirteen 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 1404 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
503(C)) or Article Thirteen, 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 1404.  Conditions to Defeasance or Covenant Defeasance.
               -----------------------------------------------

          The following shall be the conditions to the application of Section
1402 or Section 1403 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

                                       90
<PAGE>
 
     by Section 609 and agrees to comply with the provisions of this Article
     applicable to it) as trust funds in trust for the purpose of making the
     following payments, specifically pledged as security for, and dedicated
     solely to, the benefits of the Holders of such Securities, (A) money in an
     amount, or (B) U.S. Government Obligations which through the scheduled
     payment of principal and interest in respect thereof in accordance with
     their terms will provide, not later than one day before the due date of any
     payment, money in an amount, or (C) a combination thereof, 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.

          (2)  In the event of an election to have Section 1402 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

                                       91
<PAGE>
 
     that (A) the Company has received from, or there has been published by, the
     Internal Revenue Service a ruling or (B) since the date of this instrument,
     there has been a change in the applicable Federal income tax law, in either
     case (A) or (B) 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.

          (3)  In the event of an election to have Section 1403 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 (it being
     understood that this condition shall not be deemed satisfied until after
     such 90th day).

          (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).

                                       92
<PAGE>
 
          (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)  At the time of such deposit, (A) no default in the payment of any
     principal of or premium or interest on any Senior Debt shall have occurred
     and be continuing, (B) no event of default with respect to any Senior Debt
     shall have resulted in such Senior Debt becoming, and continuing to be, due
     and payable prior to the date on which it would otherwise have become due
     and payable (unless payment of such Senior Debt has been made or duly
     provided for), and (C) no other event of default with respect to any Senior
     Debt shall have occurred and be continuing permitting (after notice or
     lapse of time or both) the holders of such Senior Debt (or a trustee on
     behalf of such holders) to declare such Senior Debt due and payable prior
     to the date on which it would otherwise have become due and payable.

         (10)  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 1405.  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 and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee or other qualifying trustee (solely for purposes of this
Section and Section 1406, the Trustee and any such other trustee are referred to
collectively as the "Trustee") pursuant to Section 1404 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

                                       93
<PAGE>
 
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 and U.S.
Government Obligations so held in trust shall not be subject to the provisions
of Article Thirteen.

          The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1404 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 held by it as provided in Section 1404 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 1406.  Reinstatement.
               ------------- 

          Anything herein to the contrary notwithstanding, if and to the extent
the deposited money or U.S. Government Obligations (or the proceeds thereof)
either (i) cannot be applied by the Trustee in accordance with Section 1405
because of a court order or (ii) are for any reason insufficient in amount, then
the Company's obligations to pay principal of (and premium, if any) and interest
on the Securities of such series shall be reinstated as though no deposit had
occurred pursuant to this Article Fourteen until such time as the Trustee or
Paying Agent is permitted to apply all such money in accordance with Section
1405; provided, however, that if the Company makes any payment of principal of
      --------  -------                                                       
(and premium, if any) and interest on any such Security following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the money held by
the Trustee or the Paying Agent.  In any case specified in clause (i), the
Company's interest in the deposited money and U.S. Government Obligations (and
proceeds thereof) shall be reinstated to the extent the Company's payment
obligations are reinstated.

                              WARRANT AGREEMENT


     WARRANT AGREEMENT dated as of __________, 1994 between First Security
Corporation, a Delaware corporation (the "Company"), and First Security Bank of
Utah, N.A., a national banking association, as Warrant Agent (the "Warrant
Agent").

     The Company may issue warrants as hereinafter described (the "Warrants") to
purchase shares (the "Shares") of the common stock of the Company, par value
$1.25 per share (the "Common Stock"), from time to time and on a delayed basis
as permitted by Rule 415 of the Securities and Exchange Commission.  Such
Warrants have been registered for this purpose under a registration statement on
Form S-3 filed by the Company on March 10, 1994 and covering up to $300,000,000
of unspecified securities, including Warrants.

     The Company wishes the Warrant Agent to act on its behalf and the Warrant
Agent is willing to act in connection with the issuance, division, transfer,
exchange and exercise of Warrants.

     In consideration of the foregoing and for the purpose of defining the terms
and provisions of the Warrants and the respective rights and obligations
thereunder of the Company, the Warrant Agent and the registered owners of the
Warrants (the "Holders"), the Company and the Warrant Agent hereby agree as
follows:


Section 1.  Appointment of Warrant Agent

     The Company hereby appoints Warrant Agent to act as agent for the Company
in accordance with the instructions hereinafter in the Agreement set forth, and
the Warrant Agent hereby accepts such appointment.


Section 2.  Transferability and Form of Warrant

     2.1.  Registration.  When and as issued by the Company, the Warrants shall
be numbered and shall be registered in a Warrant Register.  The Company and the
Warrant Agent shall be entitled to treat the Holder of any Warrant as the owner
in fact thereof for all purposes and shall not be bound to recognize any
equitable or other claim to or interest in such Warrant on the part of any other
person, and shall not be liable for any registration of transfer of Warrants
which are registered or to be registered in the name of a fiduciary or the
nominee of a fiduciary unless made with actual knowledge that a fiduciary or
nominee is committing a breach of trust in requesting such registration of
transfer, or with such knowledge of such facts that its participation therein
amounts to bad faith.

     2.2.  Transfer.  When and as issued by the Company, the Warrants shall be
transferable only on the books of the Company maintained at the principal office
of the Warrant Agent in Salt Lake City, Utah upon delivery thereof duly endorsed
by a Holder or by its duly authorized attorney or representative, or accompanied
by proper evidence of succession, assignment, or authority to transfer.  In all
cases of transfer by an attorney, the original letter of attorney, duly
approved, or an official copy thereof, duly certified, shall be deposited and
remain with the Warrant Agent.  In case of transfer by executors,
administrators, guardians or other legal representatives, duly authenticated
evidence of their authority shall be produced, and may be required to be
deposited and remain with the Warrant Agent in its discretion.  Upon any
registration of transfer, the Warrant Agent shall countersign and deliver new
Warrants to the person entitled thereto.

     2.3.  Form of Warrants.  The text of the Warrants and of the form of
election to purchase Shares shall be substantially as set forth in Exhibit A
attached hereto.  The Warrants shall be executed on behalf of the Company by its
President or one of its Vice Presidents, under its corporate seal reproduced
thereon attested by its Secretary or an Assistant Secretary.  The signature of
any of these officers on the Warrants may be manual or facsimile.

     Warrants bearing the manual or facsimile signatures of individuals who were
at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any one of them shall have ceased to
hold such offices prior to the delivery of such Warrants or did not hold such
office on the date of this Agreement.

     Warrants shall be dated as of the date of counter-signature thereof by the
Company either upon initial issuance or upon division, exchange, substitution,
or transfer.

     2.4.  Countersignature of Warrants.  The Warrants shall be countersigned by
the Warrant Agent (or any successor to the Warrant Agent then acting as warrant
agent under this Agreement) and shall not be valid for any purpose unless so
countersigned.  Warrants may be countersigned, however, by the Warrant Agent (or
by its successor as warrant agent hereunder) and may be delivered by the Warrant
Agent, notwithstanding that the persons whose manual or facsimile signatures
appear thereon as proper officers of the Company shall have ceased to be such
officers at the time of such countersignature, issuance, or delivery.  The
Warrant Agent shall, upon written instructions of the President or Secretary of
the Company, countersign, issue and deliver Warrants entitling the Holders
thereof to purchase the amount of Shares established per Warrant by the
applicable Prospectus Supplement (subject to adjustment pursuant to Section 10
hereof) and shall countersign and deliver Warrants as otherwise provided in this
Agreement.


Section 3.  Exchange of Warrant Certificates

     Warrant certificates may be exchanged for another certificate or
certificates entitling the Holder thereof to purchase a like aggregate number of
Shares as the certificate or certificates surrendered then entitle such Holder
to purchase.  Any Holder of a Warrant desiring to exchange Warrant certificates
shall make such request in writing delivered to the Company, and shall
surrender, properly endorsed, the certificate or certificates evidencing the
Warrant or Warrants to be so exchanged.  Thereupon, the Warrant Agent shall
countersign and deliver to the person entitled thereto a new Warrant certificate
or certificates, as the case may be, as so requested.


Section 4.  Term of Warrants; Exercise of Warrants

     4.1  Term.  Each Warrant may be exercised in full or from time to time in
part at any time, as specified herein, on or after _____________ and at or
before _____ .m., _________ time, on ___________ or such later date as the
Company may designate, by notice to the Warrant Agent and the Holders mailed to
their addresses as set forth in the Warrant Register (the "Expiration Date").
Each Warrant not exercised at or before _____ .m., _________ time, on the
Expiration Date shall become void, and all rights of the Holder evidencing such
Warrant under this Agreement shall cease.  Upon surrender of a Warrant together
with the Warrant Price to the Company at the principal office of the Warrant
Agent, the holder of such Warrant will be issued the number of Shares in respect
of which such Warrant is then exercised.  Payment of the aggregate Warrant Price
shall be made in cash or by certified or cashier's check.

     4.2  Exercise.  Upon such surrender of Warrants and payment of the Warrant
Price as aforesaid, the Company shall issue and cause to be delivered with all
reasonable dispatch to or upon the written order of the Holder and in such name
or names as the Holder may designate, a certificate or certificates for the
number of full Shares so purchased upon the exercise of such Warrants, together
with cash, as provided in Section 11 hereof, in respect of any fractional Shares
otherwise issuable upon such surrender.  Such certificate or certificates shall
be deemed to have been issued and any person so designated to be named therein
shall be deemed to have become a holder of record of such Shares as of the date
of the surrender of such Warrants and payment of the Warrant Price, as
aforesaid; provided, however, that if, at the date of surrender of such Warrants
and payment of such Warrant Price, the transfer books for the Shares or other
class of stock purchasable upon the exercise of such Warrants shall be closed,
the certificates for the Shares in respect of which such Warrants are then
exercised shall be issuable as of the date on which such books shall next be
opened (whether before or after the Expiration Date) and until such date the
Company shall be under no duty to deliver any certificate for such Shares;
provided further, however, that the transfer books of record, unless otherwise
required by law, shall not be closed at any one time for a period longer than
twenty days.  The rights of purchase represented by the Warrants shall be
exercisable, at the election of the Holders thereof either in full or from time
to time in part and, in the event that a certificate evidencing Warrants is
exercised in respect of less than all of the Shares specified therein at any
time prior to the date of expiration of the Warrants, a new certificate
evidencing the remaining Warrant or Warrants will be issued, and the Warrant
Agent is hereby irrevocably authorized to countersign and to deliver the
required new Warrant certificates pursuant to the provisions of this Section and
of Section 2.4 hereof and the Company, whenever required by the Warrant Agent,
will supply the Warrant Agent with Warrant certificates duly executed on behalf
of the Company for such purpose.


Section 5.  Payment of Taxes
<PAGE>
 
     The Company will pay all documentary stamp taxes, if any, attributable to
the initial issuance of Shares issuable upon the exercise of Warrants; provided,
however, that the Company shall not be required to pay any tax or taxes which
may be payable in respect of any transfer involved in the issue or delivery of
any Warrants or certificates for Shares.


Section 6.  Mutilated or Missing Warrants

     In case any of the certificates evidencing the Warrants shall be mutilated,
lost, stolen or destroyed, the Company may, in its discretion, issue and deliver
in exchange and substitution for and upon cancellation of the mutilated Warrant
certificate, or in lieu of and substitution for the Warrant certificate lost,
stolen or destroyed, a new Warrant certificate of like tenor and representing an
equivalent right or interest; but only upon receipt of evidence satisfactory to
the Company and the Warrant Agent of such loss, theft or destruction of such
Warrant and indemnity, if requested, also satisfactory to them.  Applicants for
such substitute Warrant certificate shall also comply with such other reasonable
regulations and pay such other reasonable charges as the Company or the Warrant
Agent may prescribe.


Section 7.  Reservation of Shares

     There have been reserved, and the Company shall at all times keep reserved,
out of its authorized Common Stock a number of shares of Common Stock sufficient
to provide for the exercise of the rights of purchase represented by the
outstanding Warrants.  The Transfer Agent for the Common Stock (the Transfer
Agent) and every subsequent transfer agent for any shares of the Company's
capital stock issuable upon the exercise of any of the rights of purchase
aforesaid will be irrevocably authorized and directed at all times to reserve
such number of authorized shares as shall be requisite for such purpose.  The
Company will keep a copy of this Agreement on file with the Transfer Agent for
the Common Stock and with every subsequent transfer agent for any shares of the
Company's capital stock issuable upon the exercise of the rights of purchase
represented by the Warrants.  The Warrant Agent is irrevocably authorized to
requisition from time to time from such Transfer Agent such stock certificates
required to honor outstanding Warrants upon exercise thereof in accordance with
the terms of this Agreement.  The Company will supply such Transfer Agent with
duly executed stock certificates for such purpose and will provide or otherwise
make available any cash which may be payable as provided in Section 11 hereof.
All Warrants surrendered in the exercise of the rights thereby evidenced shall
be canceled by the Warrant Agent and shall thereafter be delivered to the
Company.  Promptly after the Expiration Date, and subject to the provision of
Section 4.1 hereof, the Warrant Agent shall certify to the Company the aggregate
number of Warrants then outstanding, and thereafter no shares shall be subject
to reservation in respect of such Warrants.


Section 8.  Purchase or Redemption of Warrants by the Company

     8.1.  Purchase of Warrants.  The Company shall have the right, except as
limited by law, other agreements or herein, to purchase or otherwise acquire
Warrants at such times, in such manner and for such consideration as it may deem
appropriate.

     8.2.  Redemption of Warrants by the Company.  The Company shall have the
right, except as limited by law, other agreements or herein, to redeem the
Warrants, in whole only, on thirty days' notice at $       per Warrant (as
adjusted pursuant to Section 10 hereof) at any time after one year from the date
of issuance of the Warrants if the average closing bid price of the Common Stock
(or closing price if then traded on a national securities exchange) for any
thirty consecutive trading days has equalled or exceeded $__________.  Notice of
any such redemption will be mailed by the Company to the Holders.  Unless, prior
to the expiration of such thirty day notice period, a Holder exercises his right
to purchase the Shares of Common Stock covered by his Warrants, such Holder will
forfeit his right to do so, and will be entitled only to the redemption price of
such Warrants if redeemed.

     8.3.  Cancellation of Warrants.  In the event the Company shall purchase,
redeem, or otherwise acquire Warrants, the same shall thereupon be delivered to
the Warrant Agent and be canceled by it and retired.  The Warrant Agent shall
cancel any Warrant surrendered for exchange, substitution, transfer, or exercise
in whole or in part.


Section 9.  Warrant Price

     During the period from ___________, through and including _________, the
exercise price of each Warrant will be ______________ (the "Warrant Price").
[During the period from _____________, through and including ____________, the
exercise price of each Warrant will be ________________.]  The Warrant Price
shall be subject to adjustment pursuant to Section 10 hereof.


Section 10.  Adjustment of Warrant Price and Number of Shares

     The number and kind of securities purchasable upon the exercise of each
Warrant and the Warrant Price shall be subject to adjustment from time to time
upon the happening of certain events, as follows:

     10.1.  Adjustments.  The number of Shares purchasable upon the exercise of
each Warrant and the Warrant Price shall be subject to adjustment as follows:

     (a)  In case the Company shall (i) pay a dividend in shares of Common Stock
or make a distribution in shares of Common Stock, (ii) subdivide its outstanding
shares of Common Stock, (iii) combine its outstanding shares of Common Stock
into a smaller number of shares of Common Stock or (iv) issue by
reclassification of its shares of Common Stock other securities of the Company,
the number of Shares purchasable upon exercise of each Warrant immediately prior
thereto shall be adjusted so that the Holder of each Warrant shall be entitled
to receive the kind and number of Shares or other securities of the Company
which he would have owned or have been entitled to receive after the happening
of any of such event or any record date with respect thereto.  An adjustment
made pursuant to this paragraph (a) shall become effective immediately after the
effective date of such event retroactive to the record date, if any, for such
event.

     (b)  In case the Company shall issue rights, options or warrants to all or
substantially all holders of its shares of Common Stock, without any charge to
such holders, entitling them to subscribe for or purchase shares of Common Stock
at a price per share which is lower at the record date mentioned below than the
current market price per share of Common Stock (as defined in paragraph (d)
below), the number of Shares thereafter purchasable upon the exercise of each
Warrant shall be determined by multiplying the number of Shares theretofore
purchasable upon exercise of each Warrant by a fraction, of which the numerator
shall be the number of shares of Common Stock outstanding on the date of
issuance of such rights, options or warrants plus the number of additional
shares of Common Stock offered for subscription or purchase, and of which the
denominator shall be the number of shares of Common Stock outstanding on the
date of issuance of such rights, options or warrants plus the number of shares
which the aggregate offering price of the total number of shares of Common Stock
so offered would purchase at such current market price.  Such adjustment shall
be made whenever such rights, options or warrants are issued, and shall become
effective retroactively immediately after the record date for the determination
of stockholders entitled to receive such rights, options or warrants.

     (c)  In case the Company shall distribute to all or substantially all
holders of its shares of Common Stock evidences of its indebtedness or assets
(excluding cash dividends or distributions paid from retained earnings of the
Company) or rights, options or warrants or convertible securities containing the
right to subscribe for or purchase shares of Common Stock (excluding those
referred to in paragraph (b) above) then in each case the number of Shares
thereafter purchasable upon the exercise of each Warrant shall be determined by
multiplying the number of Shares theretofore purchasable upon exercise of the
Warrant, by a fraction, of which the numerator shall be the then current market
price per share of Common Stock (as defined in paragraph (d) below) on the date
of such distribution, and of which the denominator shall be such current market
price per share of Common Stock, less the then fair value (as determined by the
Board of Directors of the Company, whose determination shall be conclusive) of
the portion of the assets or evidences of indebtedness so distributed or of such
subscription rights, options or warrants, or of such convertible securities
applicable to one share of Common Stock.  Such adjustment shall be made whenever
any such distribution is made, and shall become effective on the date of
distribution retroactive to the record date for the determination of
shareholders entitled to receive such distribution.

     (d)  For the purposes of this Agreement the current or closing market price
per share of Common Stock of the Company at any date shall be deemed to be the
average daily per share closing price in the NASDAQ National Market System for
the twenty (20) consecutive trading days immediately preceding the date for
which the determination of current or closing market price is to be made.  The
closing price referred to in clause (ii) above shall be the last reported sales
price or, in case no such reported sale takes place on such day, the average of
the reported closing bid and asked prices in the NASDAQ National Market System.

     (e)  No adjustment in the number of Shares purchasable by exercise of a
Warrant shall be made unless such adjustment would require an increase or
decrease of at least 1 percent in the number of Shares purchasable upon the
exercise of each Warrant; provided, however, that any adjustments which by
reason of this paragraph (e) are not required to be made shall be carried
forward and taken into account in any subsequent adjustment.
<PAGE>
 
     (f)  Whenever the number of Shares purchasable upon the exercise of each
Warrant is adjusted, as herein provided, the Warrant Price per Share payable
upon exercise of each Warrant shall be adjusted by multiplying such Warrant
Price immediately prior to such adjustment by a fraction, of which the numerator
shall be the number of Shares purchasable upon the exercise of each Warrant
immediately prior to such adjustment, and of which the denominator shall be the
number of Shares so purchasable immediately thereafter.

     (g)  In case the Company shall sell and issue shares of Common Stock, or
rights, options, warrants or convertible securities containing the right to
subscribe for or purchase shares of Common Stock, at a price per share of Common
Stock (determined in the case of such rights, options, warrants or convertible
securities, by dividing (i) the total amount received or receivable by the
Company in consideration of the sale and issuance of such rights, options,
warrants or convertible securities, plus the total consideration payable to the
Company upon exercise or conversion thereof, by (ii) the total number of shares
of Common Stock covered by such rights, options, warrants or convertible
securities) lower than the current market price (as defined in paragraph (d)
above) in effect immediately prior to such sale and issuance, then the Warrant
Price shall be reduced to a price (calculated to the nearest cent) determined by
dividing (i) an amount equal to the sum of (l) the number of shares of Common
Stock outstanding immediately prior to such sale and issuance multiplied by the
then existing Warrant Price, plus (2) the consideration received by the Company
upon such sale and issuance, by (ii) the total number of shares of Common Stock
outstanding immediately after such sale and issuance, provided, however, that
adjustments pursuant to this paragraph (g) shall only be made if such sale or
issuance is to an officer, director or other affiliate of the Company, or any
relative of any of the above, and if no adjustment for such sale or issuance is
made pursuant to paragraph (c) above.  The number of Shares purchasable upon the
exercise of each Warrant shall be that number determined by multiplying the
number of Shares issuable upon exercise immediately prior to such adjustment by
a fraction, of which the numerator is the Warrant Price in effect immediately
prior to such adjustment and the denominator is the Warrant Price as so
adjusted.  For the purposes of such adjustments, the shares of Common Stock
which the holders of any such rights, options, warrants or convertible
securities shall be entitled to subscribe for or purchase shall be deemed to be
issued and outstanding as of the date of such sale and issuance and the
consideration received by the Company therefor shall be deemed to be the
consideration received by the Company for such rights, options, warrants or
convertible securities, plus the consideration or premiums stated in such
rights, options, warrants, or convertible securities to be paid for the shares
of Common Stock, covered thereby.  In case the Company shall sell and issue
shares of Common Stock, or rights, options, warrants, or convertible securities
containing the right to subscribe for or purchase shares of Common Stock, for a
consideration consisting, in whole or in part, of property other than cash or
its equivalent, then in determining the "price per share of Common Stock" and
the "consideration received by the Company" for purposes of the first sentence
of this paragraph (g), the Board of Directors shall determine, in its
discretion, the fair value of said property and such determination, if made in
good faith, shall be binding upon all Holders of Warrants.  There shall be no
adjustment of the Warrant Price pursuant to this paragraph (g) if the amount of
such adjustment would be less than $.05 per Share; provided, however, that any
adjustment which by reason of this provision is not required to be made shall be
carried forward and taken into account in any subsequent adjustment.

     (h)  Whenever the number of Shares purchasable upon the exercise of each
Warrant or the Warrant Price of such Shares is adjusted, as herein provided, the
Company shall cause the Warrant Agent to promptly mail by first class mail,
postage prepaid, to each Holder of a Warrant or Warrants notice of such
adjustment or adjustments together with a certificate of a firm of independent
public accountants selected by the Board of Directors of the Company (who may be
the regular accountants employed by the Company) setting forth the number of
Shares purchasable upon the exercise of each Warrant and the Warrant Price of
such Shares after such adjustment, a brief statement of the facts requiring such
adjustment and the computation by which such adjustment was made.  Such
certificate shall be conclusive evidence of the correctness of such adjustment.
The Warrant Agent shall be entitled to rely on such certificate and shall be
under no duty or responsibility with respect to any such certificate, except to
exhibit the same, from time to time, to any holder of a Warrant or Warrants
desiring an inspection thereof during reasonable business hours.  The Warrant
Agent shall not at any time be under any duty or responsibility to any Holders
of Warrants to determine whether any facts exist which may require any
adjustment of the Warrant Price or the number of Shares or other stock or
property purchasable or with respect to the nature or extent of any such
adjustment when made, or with respect to the method employed in making such
adjustment.

     (i)  For the purpose of this subsection 10.1, the term "Shares of Common
Stock" shall mean (i) the class of stock designated as the Common Stock of the
Company at the date of this Agreement, or (ii) any other class of stock
resulting from successive changes or reclassification of such Shares consisting
solely of changes in par value, or from par value to no par value, or from no
par value to par value.  In the event that at any time, as a result of an
adjustment made pursuant to this subsection 10.1, the Holders of a Warrant or
Warrants shall become entitled to purchase any Shares of the Company other than
Shares of Common Stock, thereafter the number of such other Shares so
purchasable upon exercise of each Warrant and the Warrant Price of such Shares
shall be subject to adjustment from time to time in a manner and on terms as
nearly equivalent as practicable to the provisions with respect to the Shares
contained in paragraphs (a) through (h), inclusive, above, and the provisions of
Section 4 and subsections 10.2 through 10.4, inclusive, with respect to the
Shares shall apply on like terms to any such other Shares.

     (j)  Upon the expiration of any rights, options, warrants or conversion
privileges, if any thereof shall not have been exercised, the number of shares
purchasable upon exercise of a Warrant and the Warrant Price to the extent the
Warrant shall not then have been exercised, shall, upon such expiration, be
readjusted and shall thereafter be such as they would have been had it been
originally adjusted (or had the original adjustment not been required, as the
case may be) on the basis of (1) the only shares of Common Stock so issued were
the shares of Common Stock, if any, actually issued or sold upon the exercise of
such rights, options, warrants or conversion rights and (2) such shares of
Common Stock, if any, were issued or sold for the consideration actually
received by the Company upon such exercise plus the consideration, if any,
actually received by the Company for the issuance, sale or grant of all of such
rights, options, warrants or conversion rights whether or not exercised;
provided, further, that no such readjustment shall have the effect of increasing
the Warrant Price by an amount in excess of the amount of the adjustment
initially made in respect of the issuance, sale or grant of such rights,
options, warrants or convertible rights.

     10.2.  No Adjustment for Dividends.  Except as provided in subsection 10.1,
no adjustment in respect of any dividends shall be made during the term of the
Warrants or upon the exercise of the Warrants.

     10.3.  Preservation of Purchase Rights upon Reclassification,
Consolidation, etc.  In case of any consolidation of the Company with or merger
of the Company into another corporation or in case of any sale or conveyance to
another corporation of the property, assets or business of the Company as an
entirety or substantially as an entirety, the Company or such successor or
purchasing corporation, as the case may be, shall execute with the Warrant Agent
an agreement that each Holder of a Warrant shall have the right thereafter upon
payment of the Warrant Price in effect immediately prior to such action to
purchase upon exercise of each Warrant the kind and amount of Shares and other
securities and property which he would have owned or have been entitled to
receive after the happening of such consolidation, merger, sale or conveyance
had such Warrant been exercised immediately prior to such action.  Such
agreement shall provide for adjustments, which shall be as nearly equivalent as
may be practicable to the adjustments provided for in this Section 10.  The
Company shall mail by first class mail, postage prepaid, to the Holder of each
Warrant, notice of the execution of any such agreement.  The provisions of this
subsection 10.3 shall similarly apply to successive consolidations, mergers,
sales, or conveyances.  The Warrant Agent shall be under no duty or
responsibility to determine the correctness of any provisions contained in any
such agreement relating either to the kind or amount of Shares of stock or other
securities or property receivable upon exercise of Warrants or with respect to
the method employed and provided therein for any adjustments.

     10.4.  Statement on Warrants.  Irrespective of any adjustments in the
Warrant Price or the number or kind of Shares purchasable upon the exercise of
the Warrants, Warrants theretofore or thereafter issued may continue to express
the same price and number and kind of Shares as are stated in the Warrants
initially issuable pursuant to this Agreement.


Section 11.  Fractional Interests

     The Company shall not be required to issue fractional Shares on the
exercise of Warrants.  If more than one Warrant shall be presented for exercise
in full at the same time by the same Holder, the number of full Shares which
shall be issuable upon the exercise thereof shall be computed on the basis of
the aggregate number of Shares represented by the Warrants so presented.  If any
fraction of a Share would, except for the provisions of this Section 11, be
issuable on the exercise of any Warrant (or specified portion thereof), the
Company shall pay an amount in cash equal to the current market price per Share
(as defined in Section 10.1(d) above) multiplied by such fraction.


Section 12.  No Right as Stockholders; Notices to Warrant Holders

     Nothing contained in this Agreement or in any of the Warrants shall be
construed as conferring upon the Holders or their transferees the right to vote
or to receive dividends or to consent or to receive notice as stockholders in
respect of any meeting of stockholders for the election of directors of the
Company or any other matter, or any rights whatsoever as stockholders of the
Company.  If, however, at any time prior to the expiration of the Warrants and
prior to their exercise, any of the following events shall occur:

     (a)  any action which would require an adjustment pursuant to subsections
          10.1 or 10.3, or

     (b)  a dissolution, liquidation, or winding up of the Company (other than
          in connection with a consolidation, merger, or sale of all or
          substantially all of its property, assets, and business as an
          entirety) shall be proposed;
<PAGE>
 
then in any one or more of said events, the Company shall (a) give notice in
writing of such event to the Holders as provided in Section 17 hereof and (b)
cause notice of such event to be published once in one or more newspapers
printed in the English language and in general circulation in the cities of New
York, New York and Salt Lake City, Utah.  Failure to publish or mail such notice
or any defect therein or in the publication or mailing thereof shall not affect
the validity of any action taken in connection with such dividend, distribution,
or subscription rights, or proposed dissolution, liquidation or winding up.


Section 13.  Disposition of Proceeds on Exercise of Warrants; Inspection of
             Warrant Agreement

     The Warrant Agent shall account promptly to the Company with respect to
Warrants exercised and concurrently pay to the Company all moneys received by
the Warrant Agent for the purchase of the Shares through the exercise of such
Warrants.

     The Warrant Agent shall keep copies of this Agreement and any notices given
or received hereunder available for inspection by Holders of Warrants during
normal business hours at its principal office in Salt Lake City, Utah.  The
Company shall supply the Warrant Agent from time to time with such numbers of
copies of this Agreement as the Warrant Agent may request.


Section 14.  Merger or Consolidation or Change of Name of Warrant Agent

     Any corporation into which the Warrant Agent may be merged or with which it
may be consolidated, or any corporation resulting from any merger or
consolidation to which the Warrant Agent shall be a party, or any corporation
succeeding to the corporate trust business of the Warrant Agent, shall be the
successor to the Warrant Agent hereunder without the execution or filing of any
paper or any further act on the part of any of the parties hereto, provided that
such corporation would be eligible for appointment as a successor Warrant Agent
under the provisions of Section 16 hereof.  In case at the time such successor
to the Warrant Agent shall succeed to the agency created by this Agreement, any
of the Warrants shall have been countersigned but not delivered, any such
successor to the Warrant Agent may adopt the countersignature of the original
Warrant Agent and deliver such Warrants so countersigned; and in case at that
time any of the Warrants shall not have been countersigned, any successor to the
Warrant Agent may countersign such Warrants either in the name of the
predecessor Warrant Agent or in the name of the successor Warrant Agent; and in
all such cases Warrants shall have the full force provided in the Warrants and
in this Agreement.

     In case at any time the name of the Warrant Agent shall be changed and at
such time any of the Warrants shall have been countersigned but not delivered,
the Warrant Agent may adopt the countersignatures under its prior name and
deliver Warrants so countersigned; and in case at that time any of the Warrants
shall not have been countersigned, the Warrant Agent may countersign such
Warrants either in its prior name or in its changed name; and in all such cases
such Warrants shall have the full force provided in the Warrants and in this
Agreement.


Section 15.  Concerning the Warrant Agent

     The Warrant Agent undertakes the duties and obligations imposed by this
Agreement upon the following terms and conditions, by all of which the Company
and the Holders of Warrants, by their acceptance thereof, shall be bound:

     15.1.  The statements contained herein and in the Warrants shall be taken
as statements of the Company and the Warrant Agent assumes no responsibility for
the correctness of any of the same except such as describe the Warrant Agent or
action taken by it.  The Warrant Agent assumes no responsibility with respect to
the distribution of the Warrants except as herein otherwise provided.

     15.2.  The Warrant Agent shall not be responsible for any failure of the
Company to comply with any of the covenants contained in this Agreement or in
the Warrants to be complied with by the Company.

     15.3.  The Warrant Agent may execute and exercise any of the rights or
powers hereby vested in it or perform any duty hereunder either itself or by or
through its attorneys, agents or employees, and the Warrant Agent shall not be
answerable or accountable for any act, default, neglect or misconduct of any
such attorneys, agents, or employees or for any loss to the Company resulting
from such neglect or misconduct provided reasonable care shall have been
exercised in the selection and continued employment thereof.

     15.4.  The Warrant Agent may consult at any time with legal counsel
satisfactory to it (who may be counsel for the Company) and the Warrant Agent
shall incur no liability or responsibility to the Company or to any Holder of
any Warrant in respect of any action taken, suffered or omitted by it hereunder
in good faith and in accordance with the opinion or the advice of such counsel.

     15.5.  Whenever in the performance of its duties under the Agreement the
Warrant Agent shall deem it necessary or desirable that any fact or matter be
provided or established by the Company prior to taking or suffering any action
hereunder, such fact or matter (unless other evidence in respect thereof be
herein specifically prescribed) may be deemed to be conclusively proven and
established by a certificate signed by the President or a Vice President or the
Treasurer or the Secretary of the Company and delivered to the Warrant Agent;
and such certificate shall be full authorization to the Warrant Agent for any
action taken or suffered in good faith by it under the provisions of this
Agreement in reliance upon such certificate.

     15.6.  The Company agrees to pay the Warrant Agent reasonable compensation
for all services rendered by the Warrant Agent in the performance of its duties
under this Agreement, to reimburse the Warrant Agent for all expenses, taxes and
governmental charges and other charge of any kind and nature incurred by the
Warrant Agent in the performance of its duties under this Agreement, and to
indemnify the Warrant Agent and save it harmless against any and all
liabilities, including judgments, costs, and counsel fees, for anything done or
omitted by the Warrant Agent in the performance of its duties under this
Agreement except as a result of the Warrant Agent's negligence or bad faith.

     15.7.  The Warrant Agent shall be under no obligation to institute any
action, suit or legal proceeding or to take any other action likely to involve
expense unless the Company or one or more Holders of Warrants shall furnish the
Warrant Agent with reasonable security and indemnity for any costs and expenses
which may be incurred, but this provision shall not affect the power of the
Warrant Agent to take such action as the Warrant Agent may consider proper,
whether with or without any such security or indemnity.  All rights of actions
under this Agreement or under any of the Warrants may be enforced by the Warrant
Agent without the possession of any of the Warrants or the production thereof at
any trial or other proceeding relative thereto, and any such action, suit or
proceeding instituted by the Warrant Agent shall be brought in its name as
Warrant Agent, and any recovery of judgment shall be for the ratable benefit of
the Warrants, as their respective rights or interests may appear.

     15.8.  The Warrant Agent and any stockholder, director, officer or employee
of the Warrant Agent may buy, sell or deal in any of the Warrants or other
securities of the Company or become pecuniarily interested in any transaction in
which the Company may be interested, or contract with or lend money to or
otherwise act as fully and freely as though it were not Warrant Agent under this
Agreement.  Nothing herein shall preclude the Warrant Agent from acting in any
other capacity for the Company or for any other legal entity.

     15.9.  The Warrant Agent shall act hereunder solely as agent, and its
duties shall be determined solely by the provisions hereof.  The Warrant Agent
shall not be liable for anything which it may do or refrain from doing in
connection with this Agreement except for its own negligence or bad faith.

     15.10.  The Warrant Agent will not incur any liability or responsibility to
the Company or to any Holder of any Warrant for any action taken in reliance on
any notice, resolution, waiver, consent, order, certificate, or other paper,
document or instrument reasonably believed by it to be genuine and to have been
signed, sent or presented by the proper party or parties.

     15.11.  The Warrant Agent shall not be under any responsibility in respect
of the validity of this Warrant Agreement or the execution and delivery hereof
(except the due execution hereof by the Warrant Agent) or in respect of the
validity or execution of any Warrant (except its countersignature thereof) nor
shall the Warrant Agent by any act hereunder be deemed to make any
representation or warranty as to the authorization or reservation of any Shares
(or other stock) to be issued pursuant to this Warrant Agreement or any Warrant,
or as to whether any Shares (or other stock) will when issued be validly issued,
fully paid and nonassessable, or as to the Warrant Price or the number or amount
of Shares or other securities or other property issuable upon exercise of any
Warrant.

     15.12.  The Warrant Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from the
Chairman of the Board or the President or a Vice President or the Secretary or
the Treasurer of the Company, and to apply to such officers for advice or
instructions in connection with its duties, and shall not be liable for any
action taken or suffered to be taken by it in good faith in accordance with
instructions of any such officers.

Section 16. Change of Warrant Agent

     The Warrant Agent may resign and may be discharged from its duties under
this Agreement by giving to the Company thirty days' notice in writing.  The
Warrant Agent may be removed by like notice to the Warrant Agent from the
Company.  If the Warrant Agent shall resign or be removed or shall otherwise
become incapable of acting, the Company shall appoint a successor to the Warrant
Agent.  If the Company shall fail to make such appointment within a period of
thirty days after such removal or after it has been notified in writing of such
resignation or incapacity by the resigning or incapacitated Warrant Agent or by
the Holder of a Warrant (who shall with such notice submit his Warrant for
inspection by the Company), then the Holder of any Warrant may apply to any
court of competent jurisdiction for the appointment of a successor to the
Warrant Agent.  Any successor Warrant Agent, whether appointed by the Company or
such a court, shall be a bank or trust company in good standing, incorporated
under the laws of the United States of America or any state thereof and having
at the time of its appointment as Warrant Agent a combined capital and surplus
of at least $50,000,000.  After appointment, the successor Warrant Agent shall
be vested with the same powers, rights, duties and responsibilities as if it had
been originally named as Warrant Agent without further act or deed; but the
former Warrant Agent shall deliver and transfer to the successor Warrant Agent
any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose.  Failure
to file any notice provided for in this Section 16, however, or any defect
therein, shall not affect the legality or validity of the resignation or removal
of the Warrant Agent or the appointment of the successor warrant agent, as the
