for purchase in denominations of $1,000 or any integral multiple thereof. The
Notes are not redeemable prior to           , 1998, and will be redeemable on
such date and on any interest payment date thereafter at Firstar's option, in
whole or in part, at their principal amount plus accrued interest. See

     The Notes are direct, unsecured obligations of the Company, and are
subordinated in right of payment to all present and future Senior Indebtedness
of the Company. Payment of principal of the Notes may be accelerated only in the
case of certain events involving bankruptcy, insolvency, liquidation or

to pay principal or interest on the Notes or in the performance of any other

will be shown on, and transfers thereof will be effected only through, the

owners of beneficial interests in the Notes will not be entitled to receive the
Notes in definitive form and will not be deemed to be holders thereof. The Notes
will trade in the Depositary's Same-Day Funds settlement system until maturity,
and secondary market trading activity for the Notes will therefore settle in
immediately available funds. See "Description of the Notes--Same-Day Settlement
and Payment."

THE NOTES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND

     SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
       PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY
        REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

     Firstar is a multibank holding company providing financial services at 257
branch locations primarily throughout the states of Wisconsin and Iowa and in
the Chicago and Minneapolis-St. Paul metropolitan areas. At June 30, 1995,
Firstar had total assets of $18.6 billion and total stockholders' equity of $1.5
billion. Firstar's bank subsidiaries in Wisconsin had 128 locations and total
assets of $11.2 billion of which Firstar Bank Milwaukee, the largest commercial
bank in Wisconsin, had 65 locations and total assets of $7.1 billion. Firstar's
bank subsidiaries in Iowa (with 44 locations), Chicago (with 48 locations) and
Minneapolis-St. Paul (with 32 locations) had total assets of $2.8 billion, $3.0
billion and $2.4 billion, respectively, as of that date. At June 30, 1995,
Firstar's trust and investment management subsidiaries held $16.8 billion of
assets under active management. All of Firstar's bank subsidiaries are owned by
four sub-bank holding companies which are direct subsidiaries of Firstar.
 
     Firstar's subsidiaries offer a wide range of financial services to
businesses, individuals and governmental entities including accepting deposits,
making secured and unsecured business and personal loans, issuing and servicing
credit cards, engaging in correspondent banking services, providing trust and
investment management services, and conducting international banking services
for its local customers consisting of foreign trade financing, issuance and
confirmation of letters of credit, funds collection and foreign exchange
transactions. Firstar's subsidiaries also provide retail brokerage, mortgage
banking, insurance, and corporate computer and operational services.
 
     Firstar is incorporated in the state of Wisconsin and its principal
executive offices are located at 777 East Wisconsin Avenue, Milwaukee, Wisconsin
53201 (Telephone (414) 765-4321).
 
RECENT DEVELOPMENTS
 
     During the first half of 1995, Firstar completed three acquisitions which
added approximately $3 billion in total assets. In July 1995, Firstar announced
a fourth acquisition which will add approximately $350 million in assets.
 
     On January 31, 1995, Firstar completed its merger with First Colonial
Bankshares Corporation, a $1.8 billion bank holding company operating 33 banking
offices in the Chicago metropolitan area. The transaction was accounted for as a
pooling of interests. The total number of shares of Firstar common stock issued
was 7,700,767 shares. All financial information has been restated to reflect
this transaction.
 
     On March 31, 1995, Firstar completed its acquisition of First Moline
Financial Corporation, an $80 million thrift holding company operating in two
banking locations in Moline, Illinois. The transaction was accounted for as a
purchase with the issuance of 313,650 shares of Firstar common stock.
 
     On April 28, 1995, Firstar completed the acquisition of Investors Bank
Corp., a $1.1 billion thrift holding company operating in 12 banking locations
in the Minneapolis-St. Paul metropolitan area. The transaction was accounted for
as a pooling of interests through the issuance of 3,006,923 shares of Firstar
common stock. All financial information has been restated to reflect this
transaction.
 
     On July 24, 1995, Firstar announced that it had entered into a definitive
agreement to acquire Harvest Financial Corp., a $350 million thrift holding
company operating eight banking offices in Dubuque, Clinton and DeWitt, Iowa.
The transaction will be accounted for as a purchase and will result in the
issuance of approximately 926,000 shares of Firstar common stock. Subject to
regulatory approval, the transaction is expected to close in late 1995 or early
1996.
 
     Firstar has announced a corporate-wide restructuring program with a goal of
reaching a 55% operating expense efficiency ratio in 1997. For the six month
period ended June 30, 1995, Firstar's efficiency ratio, excluding
acquisition-related restructuring charges, was 63.8%. To reach a 55% efficiency
ratio would require either a $100 million reduction in expenses or a $180
million increase in revenue or some combination of both expense reductions and
revenue increases on an annual basis.
 
     The restructuring program is expected to be implemented over the next 18
months. Recently announced actions to merge certain existing banks in Iowa and
Wisconsin are part of this program. Charges for restructuring-related expenses,
which could be substantial, will be incurred during this period for both the
previously announced actions and as a result of other reviews of operations to
be conducted.

                                USE OF PROCEEDS
 
     The net proceeds to be received by Firstar from the sale of the Notes,
estimated to be $99,320,000, after deducting offering expenses and underwriting
commissions, will be added to the general funds of Firstar and will be available
for general corporate purposes including working capital needs; the funding of
investments in, or extensions of credit to, subsidiaries; acquisitions of other
financial institutions or other businesses or their assets; the reduction or
repayment of outstanding indebtedness; and the repurchase of outstanding equity
securities. Pending such applications, the net proceeds will be invested in
short-term investments including deposits with subsidiary banks.
 
     Firstar has engaged in a number of acquisitions in recent periods and has
generally paid for such acquisitions through the issuance of its common stock.
Firstar has announced its intention to repurchase up to 3.5 million shares of
its common stock which will be cancelled and approximately 926,000 shares of its
common stock to be reissued in connection with the acquisition of Harvest
Financial Corp. A portion of the cash needed to make these stock repurchases may
be expected to be provided from the proceeds from the sale of the Notes. It is
possible that future acquisitions may involve some cash consideration or the
purchase of shares in the open market which will be used as needed to make
acquisitions, all or a portion of which could be provided from the proceeds from
the sale of the Notes.

(1) Ratios for the six month periods ended June 30 have been annualized.
(2) The efficiency ratio is operating expenses as a percent of net interest
    revenue on a fully taxable equivalent basis and other operating revenue
    excluding securities gains or losses. The calculation excludes acquisition
    related restructuring charges in 1995 and the check kiting loss in 1994. See
    "Recent Financial Results".
(3) For purposes of computing these ratios, earnings represent income before
    income taxes plus fixed charges. Fixed charges, excluding interest on
    deposits, include interest (other than on deposits), whether expensed or
    capitalized and that portion of rental expense deemed representative of the
    interest factor. Fixed charges, including interest on deposits, include all
    interest, whether expensed or capitalized, and that portion of rental
    expense deemed representative of the interest factor.

                            RECENT FINANCIAL RESULTS
 
     Firstar reported net income for the six months ended June 30, 1995 of $90.1
million, or $1.17 per common share, down from $109.7 million, or $1.45 per
common share, for the same period last year. Return on common equity was 12.01%
for the first six months of the year, compared with 15.97% for the same period
last year, while return on assets was 1.01% compared to 1.38% during the same
period last year.
 
     In the first six months of 1995 certain merger and restructuring charges
were taken in connection with four completed acquisitions. These expenses
totaled $43.0 million pre-tax and reduced net income by $27.6 million, or 36
cents per share. In the second quarter of 1994, a $22.0 million charge was taken
in connection with a check kiting loss which reduced net income by $13.1
million, or 17 cents per share. This charge resulted from a series of fraudulent
check transactions conducted by two affiliated commercial customers.
 
     Net interest revenue during the first six months of 1995, on a taxable
equivalent basis, was $374.1 million which was $16.3 million, or 4.6%, above the
level for the same period last year. The net interest margin was 4.57% during
the first six months of 1995 compared to 4.95% for the comparable period in
1994. The increase in net interest revenue was attributable to the higher
average earning asset balances, which increased 13.2% from the six month period
ended June 30, 1994, partially offset by the reduced net interest margin. The
margin has been compressed by rising costs of funds which have not been fully
offset by increased yields on earning assets.
 
     The provision for loan losses of $23.1 million was $16.6 million higher
than last year of which $13.6 million of this increase was a merger related
adjustment to loan loss reserve levels. Net charge-offs for the first six months
were at a level of .25% of average outstanding loans compared to .10% a year
earlier. Charge-off levels for the first half of 1994 were unusually low and the
current period's level of .25% is consistent with recent experience. The reserve
for loan losses represented 1.60% of total loans at June 30, 1995 the same level
as at year-end 1994 and down from 1.72% a year earlier.
 
     Nonperforming assets were $93.7 million at June 30, 1995, which amounted to
 .75% of total loans and other real estate. This was an $11.2 million increase
from the December 31, 1994 level, which was .69% of total loans and other real
estate. Nonperforming assets have gone up in part due to the application of
Firstar's credit review policies to the loan portfolios of the recently acquired
banks. This has also accounted for some of the increased loan loss provision.
 
     Other operating revenue, excluding securities gains and losses, increased
by less than 1% to a level of $190.9 million in the first six months of 1995
compared to $189.9 million for the same period last year. Revenue from trust and
investment management rose 5% and credit card service fees were up 11%. However,
reduced mortgage banking revenues offset these gains as origination volumes are
down industry wide. Firstar continues to emphasize growth in non-interest
revenue although recent growth trends have been lower than previously
experienced.
 
     Other operating expense increased to a level of $383.8 million. Excluding
the acquisition related restructuring charges taken in the first six months of
this year and the check kiting loss in 1994, expenses increased 6.3%. Personnel
costs rose by 5.7% to a level of $202 million due in part to a bank acquisition
that occurred late in 1994. Nonpersonnel costs, excluding the restructuring
charges in 1995 and the check kiting loss in 1994, increased 7.1%. The
efficiency ratio, which is the ratio of expense to revenue, was 63.83% in the
first six months of 1995 compared to 61.94% a year earlier.
 
     Total assets on June 30, 1995 were $18.6 billion, an increase of $1.9
billion, or 11.7%, from the same time last year. Without the effect of
acquisitions, the year-to-year increase would be 8.8%.
 
     Earning assets totaled $17.0 billion on June 30, 1995, an increase of $2.0
billion, or 13.1%, over June 30, 1994. Loans, the largest category of earning
assets, represented 73.6% of earning assets as compared to 74.6% a year earlier.
Total loans were $12.5 billion on June 30, 1995, an increase of $1.6 billion, or
14.6%, over the 1994 level, which excludes loans which have been securitized and
held in Firstar's securities portfolio. Firstar
 
                                        6
<PAGE>   8
 
securitized $330 million of residential mortgages near the end of 1994. These
loans, now carrying a U.S. agency guarantee, are included in securities.
 
     Fund sources, consisting of deposits and borrowed funds, increased by $1.8
billion, or 12.1%, to $16.7 billion on June 30, 1995. Total deposits were $13.6
billion, an increase of $974 million, or 7.7%, over a year earlier.
Approximately one-half of the increase in deposits was due to a bank acquisition
that occurred late in 1994.
 
     Stockholders' equity totaled $1,541.2 million at the end of the second
quarter, an increase of $28.5 million from the level at year-end 1994 and $116.7
million over June 30, 1994. Total equity as a percent of total assets amounted
to 8.30%. Under risk-based capital rules, total capital was 12.61% of
risk-adjusted assets.
 
                            DESCRIPTION OF THE NOTES
 
     The following sets forth certain general terms and provisions of the Notes.
The Notes will be issued under an indenture (the "Indenture"), between the
Company and Chemical Bank, as trustee (the "Trustee"). A copy of the form of the
Indenture has been filed as an exhibit to the Registration Statement of which
this Prospectus forms a part. 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, including the definitions therein of certain terms. Wherever
particular sections or defined terms of the Indenture are referred to, it is
intended that such sections or definitions shall be incorporated herein by
reference.
 
     Since the Company is a holding company, the right of the Company, and hence
the right of creditors and stockholders of the Company, including the holders of
the Notes offered hereby, to participate in any distribution of assets of any
subsidiary upon its liquidation, reorganization or otherwise is necessarily
subject to the prior claims of creditors of the subsidiary, except to the extent
that the claims of the Company itself as a creditor of the subsidiary may be
recognized.
 
GENERAL
 
     The Indenture does not limit the aggregate principal amount of indebtedness
which may be issued thereunder and provides that debt securities ("Debt
Securities") may be issued from time to time in one or more series. The Notes
will be the first series of Debt Securities issued by the Company under the
Indenture. All of the Debt Securities issued under the Indenture will rank
equally and ratably with any additional Debt Securities issued thereunder.
 
     The Notes offered hereby will mature on             , 2000, and are limited
to $100 million aggregate principal amount. The Notes will bear interest at the
rate of   % per annum, commencing on             , 1995. Interest will be
payable semiannually on             and             of each year, commencing
            , 1996, to the persons in whose names the Notes are registered on
the             and             next preceding such             and
            , respectively, and at maturity to the persons to whom principal is
payable upon proper presentment. No sinking fund is provided for the Notes.
 
     The Notes will be unsecured and subordinated in right of payment to the
prior payment in full of all present and future Senior Indebtedness of the
Company as described under the caption "Description of the Notes--Subordination"
herein. Neither the Indenture nor the Notes will limit or otherwise restrict the
amount of other indebtedness which may be incurred or other securities which may
be issued by the Company. As of June 30, 1995, the Company had approximately
$43.9 million principal amount of Senior Indebtedness outstanding.
 
     Principal of and interest on the Notes will be payable, and the transfer of
Notes will be registrable, through The Depository Trust Company, as depository.
The Notes will be issued only in fully registered form without coupons in
denominations of $1,000 and integral multiples thereof.
 
     No service charge will be made for any transfer or exchange of the Notes,
but the Company may require payment of a sum sufficient to cover any tax or
other governmental charge payable in connection therewith.
 
                                        7
<PAGE>   9
 
     The Indenture does not contain any terms which would afford protection to
the holders of the Notes in the event of a recapitalization, a change of
control, a highly leveraged transaction or a restructuring involving the Company
that results in a downgrade of the Company's public debt rating.
 
     Payment of principal of the Notes may be accelerated only in the case of
certain events of bankruptcy, insolvency, liquidation or receivership of the
Company or any of its Principal Constituent Banks. The term "Principal
Constituent Bank" shall mean any subsidiary which is a bank the consolidated
assets of which, as set forth in the most recent statement of condition of such
bank, constitute 15% or more of the Company's consolidated assets as determined
from the most recent statements of condition of the Company. There will be no
right of acceleration of the payment of principal of the Notes upon a default in
the payment of interest on the Notes or in the performance of any covenant or
agreement of the Company contained in the Notes or the Indenture. The Indenture
does not limit the consolidation, merger or corporate reorganization of any of
the Company's current and future subsidiaries.
 
REDEMPTION OF NOTES
 
     The Notes may not be redeemed before             , 1998. On that date and
on any interest payment date thereafter, the Notes may be redeemed, as a whole
or from time to time in part, at the option of the Company, on not less than 30
nor more than 60 days prior notice given as provided in the Indenture, at a
redemption price equal to 100% of the principal amount of the Notes to be
redeemed plus interest accrued and unpaid to the date of redemption.
 
     If less than all of the Notes are to be redeemed, the Notes to be redeemed
shall be selected by the Trustee by such method as it shall deem fair and
appropriate and which may provide for the selection for redemption of portions
of the principal amount of the Notes of denominations larger than $1,000.
 
BOOK-ENTRY SYSTEM
 
     The Notes will be issued only in fully registered form and will be
represented by one or more global securities ("Global Securities") registered in
the name of The Depository Trust Company, New York, New York, or a successor
thereof (which successor shall be a clearing agency registered under the
Exchange Act if so required by applicable law) (The Depository Trust Company or
such successor being herein referred to as the "Depositary") or the Depositary's
nominee.
 
     Upon the issuance of a Global Security, the Depositary will credit, on its
book-entry registration and transfer system, the respective principal amount of
the Notes represented by such Global Security to the accounts of institutions
that have accounts with the Depositary ("participants"). Ownership of beneficial
interest in the Global Security will be limited to participants or persons that
may hold interests through participants. Ownership of beneficial interests in
the Global Security will be shown on, and the transfer of that ownership will be
effected only through, records maintained by the Depositary or its nominee (with
respect to interests of participants) or by participants or persons that hold
through participants (with respect to interests of persons other than
participants). The laws of certain states require that certain purchasers of
securities take physical delivery of such securities as certificates issued in
definitive form. Such limits and such laws may impair the ability to transfer
beneficial interests in a Global Security.
 
     Principal, premium, if any, and interest payments on the Global Security
will be made to the Depositary or its nominee, as the case may be, as the
registered holder thereof. The Company has been advised that the Depositary or
its nominee, upon receipt of any payment of principal, premium, if any, or
interest in respect of a Global Security, will immediately credit participants'
accounts with payments in amounts proportionate to their respective beneficial
interests in the principal amount of such Global Security as shown on the
records of the Depositary or its nominee. Payments by participants (or by
persons that hold interests for customers through participants) to owners of
beneficial interests in such Global Security held through such participants will
be governed by standing instructions and customary practices, as is now the case
with securities held for the accounts of customers registered in "street name",
and will be the responsibility of such participants (or of such persons that
hold interests for customers through participants).
 
                                        8
<PAGE>   10
 
     Each owner of a beneficial interest in a Global Security must ensure that
the person through whom its interest is held (i.e., either a participant or
other person that holds interests through a participant) maintains accurate
records of such owner's beneficial interest in the Global Security. The
interests of participants (which may be in the form of a custodial relationship)
will be shown on records maintained by the Depositary for such Global Security.
The designation of the Depositary or its nominee as custodian for participants
and persons that hold interests through participants (either as principal,
nominee or custodian) will be shown on the register maintained by the Trustee.
 
     Neither the Company nor the Trustee will have any responsibility or
liability for any aspect of the records relating to, or for payments made on
account of beneficial ownership interests in, a Global Security or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.
 
     If the Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for the Global Securities or if at any time the
Depositary ceases to be a clearing agency registered under the Exchange Act if
so required by applicable law or regulation, and, in either case, a successor
depositary is not appointed by the Company within 90 days, the Company will
issue Notes in certificated form ("Certificated Notes") in exchange for such
Global Securities. In addition, Company may at any time and in its sole
discretion determine not to have any Notes represented by Global Securities and,
in such event, will issue Certificated Notes in exchange for such Global
Securities. Furthermore, after the occurrence of an Event of Default, the
Company will issue Certificated Notes in exchange for such Global Securities.
The Certificated Notes so issued in exchange for such Global Securities shall be
in the same minimum denominations and be of like aggregate principal amount and
tenor as the portion of each such Global Security to be exchanged. Except as
provided above, owners of beneficial interests in a Global Security will not be
entitled to receive physical delivery of Certificated Notes and will not be
considered the registered holders of such Notes for any purpose (including
receiving payments of principal, premium, if any, and interest).
 
     The Depositary has advised the Company that it is a limited-purpose trust
company organized under the laws of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. The Depositary was created to
hold securities of its participants and to facilitate the clearance and
settlement of securities transactions among its participants in such securities
through electronic book-entry changes in accounts of the participants, thereby
eliminating the need for physical movement of securities certificates. The
Depositary's participants include securities brokers and dealers, banks, trust
companies, clearing corporations and certain other organizations, some of whom
(and/or their representatives) own the Depositary. Access to the Depositary's
book-entry system is also available to others, such as banks, brokers, dealers
and trust companies that clear through or maintain a custodial relationship with
a participant, either directly or indirectly.
 
SAME-DAY SETTLEMENT AND PAYMENT
 
     Settlement for the Notes will be made in immediately available funds. The
Notes will trade in the Depositary's Same-Day Funds settlement system until
maturity, unless otherwise exchanged for Certificated Notes as described above,
and therefore the Depositary will require secondary trading activity in the
Notes to be settled in immediately available funds. Secondary trading in
long-term notes and debentures of corporate issuers is generally settled in
clearing-house or next-day funds. No assurance can be given as to the effect, if
any, of settlement in immediately available funds on secondary trading activity
in the Notes.
 
SUBORDINATION
 
     During the continuance beyond any applicable grace period of any default
with respect to Senior Indebtedness (as defined below), no payment of principal
of and interest on the Notes shall be made by the Company until payment in full
of all principal of and premium and interest on such Senior Indebtedness. In
addition, upon any distribution of assets of the Company upon any dissolution,
winding up, liquidation or reorganization, the payment of the principal of and
interest on the Notes is to be subordinated to the extent provided in the
Indenture (Article Fifteen).
 
                                        9
<PAGE>   11
 
     In the event of any insolvency or bankruptcy proceedings, and any
receivership, liquidation, reorganization, arrangement or other similar
proceedings in connection therewith, relative to the Company or to its property,
and in the event of any proceedings for voluntary liquidation, dissolution or
other winding-up of the Company, whether or not involving insolvency or
bankruptcy, then the holders of Senior Indebtedness shall be entitled to receive
payment in full of all principal, premium and interest on all Senior
Indebtedness before the Holders of the Debt Securities are entitled to receive
any payment on account of principal, premium, if any, interest or Additional
Amounts (as defined in the Indenture) upon the Debt Securities, and to that end
(but subject to the power of a court of competent jurisdiction to make other
equitable provisions reflecting the rights conferred in the Debt Securities upon
Senior Indebtedness and the Holders thereof with respect to the subordinated
indebtedness represented by the Debt Securities and the Holders hereof by a
lawful plan of reorganization under applicable bankruptcy law) the holders of
Senior Indebtedness shall be entitled to receive for application in payment
thereof any payment or distribution of any kind or character, whether in cash or
property or securities, which may be payable or deliverable in any such
proceedings in respect of the Debt Securities after giving effect to any
concurrent payment or distribution in respect of such Senior Indebtedness,
except securities which are subordinate and junior in right of payment to the
payment of all Senior Indebtedness then outstanding. If any payment or
distribution shall be paid or delivered to any Holder of the Debt Securities or
to the Trustee for their benefit before all Senior Indebtedness shall have been
paid in full, such payment or distribution shall be held in trust for and so
paid and delivered to the holders of Senior Indebtedness (or their duly
authorized representatives) until all Senior Indebtedness shall have been paid
in full.
 
     For purposes of the preceding paragraphs, the term "Senior Indebtedness"
will be defined to mean the principal of, and premium, if any, and interest on,
all indebtedness of Company, whether outstanding on the date of execution of the
Indenture or thereafter incurred or created, except such indebtedness as is by
its terms expressly stated to be not superior in right of payment to the Notes
or to rank pari passu or is identified in a Board Resolution of the Company or
any indenture supplemental to the Indenture as not superior in right of payment
nor to rank pari passu with the Notes (Section 101).
 
DEFAULT; EVENT OF DEFAULT AND LIMITED RIGHTS OF ACCELERATION
 
     With respect to the Notes, the following are "Defaults" under the
Indenture: (a) failure to pay when due principal of or any premium on any of the
Notes; (b) failure to pay any interest on any Note when due and such failure
continues for 30 days; (c) failure to perform any other covenant of Firstar in
the Indenture and such failure continues for 60 days after written notice of
such default; (d) an Event of Default; and (e) any other Default provided with
respect to Notes. (Section 513). With respect to the Notes, an Event of Default
is defined under the Indenture as certain events of bankruptcy, liquidation,
insolvency or receivership of the Company or any Principal Constituent Bank.
Unless an Event of Default has occurred and shall be continuing with respect to
the Notes, neither the holders of the Notes nor the Trustee may declare the
acceleration of the payment of principal or premium, if any, of such Notes under
the Indenture.
 
     The Indenture provides that, subject to the duty of the Trustee during the
continuance of a 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
Indenture at the request or direction of any of the Holders, unless such Holders
shall have offered to the Trustee reasonable indemnity (Section 602). Subject to
certain limitations, the holders of a majority in aggregate principal amount of
the Outstanding Notes 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
Notes (Section 512).
 
     No holder of any Notes or any related coupons will have any right to
institute any proceeding with respect to the Indenture or for any remedy
thereunder, unless such holder shall have previously given to the Trustee
written notice of a continuing Default with respect to the Notes, the holders of
at least 25% in aggregate principal amount of the Outstanding Notes shall have
made written request, and offered reasonable indemnity, to the Trustee to
institute such proceeding as Trustee, and the Trustee shall not have received
from the holders of a majority in aggregate principal amount of the Outstanding
Notes a direction inconsistent with such request and shall have failed to
institute such proceeding within 60 days. (Section 507). However, such
 
                                       10
<PAGE>   12
 
limitations do not apply to a suit instituted by a holder of an Outstanding Note
for enforcement of payment of the principal of, or any premium or interest on,
such Note on or after the respective due dates expressed in such Note. (Section
508).
 
     The Company is required to furnish to the Trustee annually a statement as
to the performance by the Company of certain of its obligations under the
Indenture and as to any default in such performance (Section 1005). The Trustee
may withhold notice to Holders of any default (except in payment of principal,
premium or interest, if any) if it in good faith determines that it is in the
interests of the Holders to do so.
 
     If any Event of Default with respect to the Notes at the time outstanding
shall occur and be continuing, then and in every such case the Trustee or the
holders of not less than 25% in principal amount of the Outstanding Notes may
declare the principal amount of all of the Notes to be due and payable
immediately by a notice in writing to the Company (and to the Trustee if given
by the holders). However, at any time after such a declaration of acceleration
with respect to the Notes has been made and before a judgment or decree based on
such acceleration has been obtained by the Trustee, the holders of not less than
a majority in principal amount of the Outstanding Notes may, under certain
circumstances, rescind and annul such acceleration if all Events of Default,
have been cured or waived as provided in the Indenture (Section 502).
 
MODIFICATION AND WAIVER
 
     The Indenture provides that modifications and amendments may be made by the
Company and the Trustee with the consent of the holders of not less than a
majority in principal amount of the Outstanding Debt Securities of each series
affected thereby; provided, however, that no such modifications or amendments
may, without the consent of the holder of each Outstanding Debt Security
affected thereby (a) change the stated maturity date of the principal of, or any
installment of interest on, any Debt Security; (b) reduce the principal amount
thereof, or the rate of interest (if any) thereon, or additional amounts, if
any, in respect of, or any premium payable upon the redemption of any Debt
Security; (c) change the place of payment, coin or currency in which any Debt
Security or any premium or interest thereon is payable; (d) impair the right to
institute suit for the enforcement of any payment on or after the stated
maturity date thereof or, in the case of redemption, on or after the redemption
date; (e) reduce the above-stated percentage in principal amount of Outstanding
Debt Securities of any series, the consent of the holders of which is required
to modify or amend the Indenture; (f) reduce the percentage in principal amount
of Outstanding Debt Securities of any series, the consent of the holders of
which is required for waiver of compliance with certain provisions of the
Indenture or for waiver of certain defaults; (g) modify (with certain
exceptions) any provision of the Indenture relating to modification and
amendment of the Indenture or waiver of compliance with conditions and defaults
thereunder; (h) alter in any respect the provisions regarding subordination of
the Debt Securities in a manner adverse to the holders thereof; (i) with respect
to any Debt Securities convertible into Common Stock, adversely affect the right
of conversion; (j) reduce the principal amount of any Original Issue Discount
Securities which could be declared due and payable upon acceleration of maturity
thereof; or (k) change the obligation of the Company to pay additional amounts
(Section 902).
 
     The holders of a majority in principal amount of the Outstanding Debt
Securities of any series may on behalf of the holders of all Debt Securities of
that series waive, insofar as that series is concerned, compliance by the
Company and the Trustee, with certain restrictive provisions of the Indenture
(Section 1008). The holders of a majority in principal amount of the Outstanding
Debt Securities of any series may on behalf of the holders of all Debt
Securities of that series waive any past default under the Indenture with
respect to that series, except a default in the payment of the principal of (and
premium, if any) or interest on or additional amounts payable in respect of any
Debt Security of such series or in respect of a covenant or provision which
under the terms of the Indenture cannot be modified or amended without the
consent of the holder of each Outstanding Debt Security of such series affected
(Section 513).
 
     Modification and amendment of the Indenture may be made by the Company and
the Trustee without the consent of any holder for any of the following purposes:
(i) to evidence the succession of another Person to the Company; (ii) to add to
the covenants of the Company for the benefit of the holders of all or any series
of Debt Securities; (iii) to add any additional Defaults; (iv) to add or change
any provisions of the Indenture to
 
                                       11
<PAGE>   13
 
facilitate the issuance of Bearer Securities; (v) to add to, delete from or
revise the conditions, limitations and restrictions on the authorized amount,
terms or purposes of issue, authentication and delivery of Debt Securities as
set forth in the Indenture; (vi) to establish the form or terms of Debt
Securities of any series and any related coupons; (vii) to provide for the
acceptance of appointment by a successor Trustee; (viii) to cure any ambiguity,
defect or inconsistency in the Indenture, provided such action is not
inconsistent with the provisions of the Indenture and does not adversely affect
the interests of holders of Debt Securities of any series in any material
respect under the Indenture; (ix) to modify, eliminate or add to the provisions
of the Indenture to such extent as is necessary to conform to the obligations of
the Company and the Trustee under the Indenture to the Trust Indenture Act of
1939, as amended; or (x) to make provision for the conversion rights of the
holders of the Debt Securities in certain events (Section 901).

     The Indenture and the Notes will be governed by and construed in accordance

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Pursuant to the Wisconsin Business Corporation Law, directors and officers
of Firstar are entitled to mandatory indemnification from Firstar against
certain liabilities and expenses (i) to the extent such officers or directors
are successful in the defense of a proceeding; and (ii) in proceedings in which
the director or officer is not successful in defense thereof, unless it is
determined that the director or officer breached or failed to perform his or her
duties to Firstar and such breach or failure constituted: (a) a willful failure
to deal fairly with Firstar or its shareholders in connection with a matter in
which the director or officer had a material conflict of interest; (b) a
violation of the criminal law unless the director or officer had reasonable
cause to believe his or her conduct was lawful or had no reasonable cause to
believe his or her conduct was unlawful; (c) a transaction from which the
director or officer derived an improper personal profit; or (d) willful
misconduct. It should be noted that the Wisconsin Business Corporation Law
specifically states that it is the public policy of Wisconsin to require or
permit indemnification in connection with a proceeding involving securities
regulation, as described therein, to the extent required or permitted as
described above. Additionally, under the Wisconsin Business Corporation Law,
directors of Firstar are not subject to personal liability to Firstar, its
shareholders or any person asserting rights on behalf thereof for certain
breaches or failure to perform any duty resulting solely from their status as
directors except in circumstances paralleling those in subparagraphs (a) through
(d) outlined above.
 
     Firstar's By-Laws contain similar indemnification provisions as to
directors and officers of Firstar. In addition, Firstar has entered into
individual indemnity agreements with all of its current directors. The indemnity
agreements are virtually identical in all substantive respects to Firstar's
By-Laws.
 
     Expenses for the defense of any action for which indemnification may be
available may be advanced by Firstar under certain circumstances.
 
     Firstar maintains a liability insurance policy for officers and directors
which extends to, among other things, liability arising under the Securities Act
of 1933, as amended.
 
     In addition, Firstar's Pension Plan and Thrift and Sharing Plan provide for
indemnification of members of the plan committees and directors of Firstar as
follows:
 
          The Company shall indemnify each member of the Plan Committee and the
     Board and hold each of them harmless from the consequences of his acts or
     conduct in his official capacity, if he acted in good faith and in a manner
     he reasonably believed to be solely in the best interests of the
     Participants and their Beneficiaries, and with respect to any criminal
     action or proceeding had no reasonable cause to believe his conduct was
     unlawful. Such indemnification shall cover any and all attorneys' fees and
     expenses, judgments, fines and amounts paid in settlement, but only to the
     extent such amounts are not paid to such
 
                                      II-1

     person(s) under the Company's fiduciary insurance policy and to the extent
     that such amounts are actually and reasonably incurred by such person(s).

ITEM 17. UNDERTAKINGS
 
     (a) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 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.
 
     (b) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that, in the opinion of the Securities and Exchange
Commission, such indemnification is against the public policy as expressed in
the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against 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.
 
     (c) 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.
 
          (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.

Dear Sirs:
 
     Firstar Corporation, a Wisconsin corporation (the "Company"), confirms its
agreement with Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith
Incorporated ("Merrill Lynch") and Robert W. Baird & Co. Incorporated ("Baird")
and each of the other Underwriters named in Schedule A hereto (collectively, the
"Underwriters", which term shall also include any underwriter substituted as
hereinafter provided in Section 10 hereof), for whom Merrill Lynch and Baird are
acting as representatives (in such capacity, Merrill Lynch and Baird shall
hereinafter be referred to as the "Representatives"), with respect to the sale
by the Company and the purchase by the Underwriters, acting severally and not
jointly, of the respective principal amounts set forth in said Schedule A of
$100,000,000 aggregate principal amount of the Company's [  ]% Subordinated
Notes due 2000 (the "Securities"). The Securities are to be issued pursuant to
an indenture dated as of [  ], 1995 (the "Indenture").
 
     Prior to the purchase and public offering of the Securities by the several
Underwriters, the Company and the Representatives, acting on behalf of the
several Underwriters, shall enter into an agreement substantially in the form of
Exhibit A hereto (the "Pricing Agreement"). The Pricing Agreement may take the
form of an exchange of any standard form of written telecommunication between
the Company and the Representatives and shall specify such applicable
information as is indicated in Exhibit A hereto. The offering of the Securities
will be governed by this Agreement, as supplemented by the Pricing Agreement.
From and after the date of the execution and delivery of the Pricing Agreement,
this Agreement shall be deemed to incorporate the Pricing Agreement.
 
     The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 33-[  ]) and a related
preliminary prospectus for the registration of the Securities under the
Securities Act of 1933 (the "1933 Act"), has filed such amendments thereto, if
any, and such amended preliminary prospectuses as may have been required to the
date hereof, and will file such additional amendments thereto and such amended
prospectuses as may hereafter be required. Such registration statement (as
amended, if applicable) and the prospectus constituting a part thereof
(including in each case all documents incorporated or deemed to be incorporated
by reference therein and the information, if any, deemed to be part thereof
pursuant to Rule 430A(b) or Rule 434 of the rules and regulations of the
Commission under the 1933 Act (the "1933 Act Regulations")), as from time to
time amended or
<PAGE>   2
 
supplemented pursuant to the 1933 Act, the Securities Exchange Act of 1934, as
amended (the "1934 Act"), or otherwise, are hereinafter referred to as the
"Registration Statement" and the "Prospectus", respectively, except that if any
revised prospectus shall be provided to the Underwriters by the Company for use
in connection with the offering of the Securities which differs from the
Prospectus on file at the Commission at the time the Registration Statement
becomes effective (whether or not such revised prospectus is required to be
filed by the Company pursuant to Rule 424(b) of the 1933 Act Regulations), the
term "Prospectus" shall refer to such revised prospectus from and after the time
it is first provided to the Underwriters for such use. All references in this
Agreement to financial statements and schedules and other information which is
"contained," "included" or "stated" in the Registration Statement or the
Prospectus (and all other references of like import) shall be deemed to mean and
include all such financial statements and schedules and other information which
is or is deemed to be incorporated by reference in the Registration Statement or
the Prospectus, as the case may be; and all references in this Agreement to
amendments or supplements to the Registration Statement or the Prospectus shall
be deemed to mean and include the filing of any document under the 1934 Act
which is or is deemed to be incorporated by reference in the Registration
Statement or the Prospectus, as the case may be. If the Company elects to rely
on Rule 434 under the 1933 Act Regulations, all references to the Prospectus
shall be deemed to include, without limitation, the form of prospectus and the
abbreviated term sheet, taken together, provided to the Underwriters by the
Company in reliance on Rule 434 under the 1933 Act (the "Rule 434 Prospectus").
If the Company files a registration statement to register a portion of the
Securities and relies on Rule 462(b) for such registration statement to become
effective upon filing with the Commission (the "Rule 462 Registration
Statement"), then any reference to "Registration Statement" herein shall be
deemed to be to both the registration statement referred to above (No. 33-[ ])
and the Rule 462 Registration Statement, as each such registration statement may
be amended pursuant to the 1933 Act.
 
     The Company understands that the Underwriters propose to make a public
offering of the Securities as soon as the Representatives deem advisable after
the Registration Statement becomes effective and the Pricing Agreement has been
executed and delivered and the Indenture has been qualified under the Trust
Indenture Act of 1939, as amended (the "1939 Act").
 
     SECTION 1.  Representations and Warranties.
 
     (a) The Company represents and warrants to each Underwriter as of the date
hereof, as of the date of the Pricing Agreement (such latter date being
hereinafter referred to as the "Representation Date") and as of the Closing Time
referred to in Section 2(a) hereof, and agrees with each Underwriter, as
follows:
 
          (i) At the respective times the Registration Statement and any
     post-effective amendments thereto become effective, the Registration
     Statement and any post-effective amendments thereto will comply in all
     material respects with the requirements of the 1933 Act, the 1933 Act
     Regulations and the 1939 Act and will not contain an untrue statement of a
     material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading, and at
     the time the Registration Statement becomes effective (unless the term
     "Prospectus" refers to the Rule 424 prospectus, in which case at the time
     it is mailed or otherwise delivered to the Commission for filing) and at
     Closing Time referred to in Section 2, the Prospectus will not include an
     untrue statement of a material fact or omit to state a material fact
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading; provided,
     however, that the representations and warranties in this subsection shall
     not apply to statements in or omissions from the Registration Statement or
     Prospectus made in reliance upon and in conformity with information
     furnished to the Company in writing by any Underwriter through you
     expressly for use in the Registration Statement or Prospectus. For the
     purpose of this Section 1(a), all references to the Registration Statement,
     any post-effective amendments thereto and the Prospectus shall be deemed to
     include, without limitation, any electronically transmitted copies thereof,
     including, without limitation, any copy filed with the Commission pursuant
     to or Electronic Data Gathering, Analysis, and Retrieval system ("EDGAR").
 
          (ii) The documents incorporated by reference in the Prospectus
     pursuant to Item 12 of Form S-3 under the 1933 Act, at the time they were
     filed or last amended, as the case may be, with the
 
                                        2
<PAGE>   3
 
     Commission, complied in all material respects with the requirements of the
     1934 Act and rules and regulations of the Commission thereunder (the "1934
     Act Regulations"), and, when read together with the other information in
     the Prospectus, at the time the Registration Statement becomes effective
     and at Closing Time, will not contain an untrue statement of a material
     fact or omit to state a material fact required to be stated therein or
     necessary to make the statements therein not misleading, and any documents

          (viii) The authorized, issued and outstanding capital stock of the
     Company is as set forth in the Registration Statement under
     "Capitalization" (except for subsequent issuances, if any, pursuant to
     reservations or agreements referred to in the Prospectus); the shares of

     obligation, agreement, covenant or condition contained in any contract,
     indenture, mortgage, loan agreement, note, lease or other instrument to
     which it is a party or by which it or its property may be bound, which
     violations or defaults in the aggregate would have a material adverse
     effect on the condition, financial or otherwise, or on the earnings,
     business affairs or business prospects, of the Company and its subsidiaries
     considered as one enterprise; and the execution and delivery of this
     Agreement and the consummation of the transactions contemplated herein have
     been duly authorized by all necessary corporate action and will not
     conflict with or constitute a breach of, or default under, or result in the
     creation or imposition of any lien, charge or encumbrance upon any property
     or assets of the Company or any of its subsidiaries, except as expressly
     contemplated in the Indenture, pursuant to, any contract, indenture,

     change in the condition, financial or otherwise, or in the earnings,
     business affairs or business prospects of the Company and its subsidiaries
     considered as one enterprise, or which might reasonably be expected to
     materially and adversely affect the properties or assets thereof or the
     consummation of this Agreement or the performance by the Company of its
     obligations hereunder; the aggregate of all pending legal or governmental
     proceedings to which the Company or any subsidiary is a party or of which
     any of their respective property or assets is the subject which are not
     described in the Registration Statement, including ordinary routine
     litigation incidental to the business could not reasonably be expected to

     revocation or modification of any such certificate, authority or permit
     which, singly or in the aggregate, if the subject of an unfavorable
     decision, ruling or finding, would materially and adversely affect the
     conduct of the business, operations, financial condition or income of the
     Company and its subsidiaries considered as one enterprise.
 
          (xv) The Company and its Principal Subsidiaries have good and

     title to all personal property owned by them, in each case free and clear
     of all liens, encumbrances and defects except such as are described in the
     Prospectus or such as do not materially affect the value of such property
     and do not interfere with the use made and proposed to be made of such
     property by the Company and its Principal Subsidiaries; and any real
     property and buildings held under lease by the Company and its Principal
     Subsidiaries are held by them under valid, subsisting and enforceable
     leases with such exceptions as are not material and do not interfere with
     the use made and proposed to be made of such property and buildings by the
     Company and its Principal Subsidiaries.
 
          (xvi) The Company is a bank holding company registered under the Bank
     Holding Company Act of 1956, as amended; and the Company and its
     subsidiaries are in compliance with, and conduct their respective
     businesses in conformity with, all applicable laws and governmental
     regulations, the violation of which would have a material adverse effect on

     affairs, or business prospects of the Company and its subsidiaries
     considered as one enterprise.
 
     (b) Any certificate signed by any officer of the Company and delivered to
the Representatives or to counsel for the Underwriters shall be deemed a
representation and warranty by the Company to each Underwriter as to the matters
covered thereby.
 
     SECTION 2.  Sale and Delivery to Underwriters; Closing.
 
     (a) On the basis of the representations and warranties herein contained and
subject to the terms and conditions herein set forth, the Company agrees to sell
to each Underwriter, severally and not jointly, and each Underwriter, severally
and not jointly, agrees to purchase from the Company, at the price set forth in
the Pricing Agreement, the aggregate principal amount of Securities set forth in
Schedule A opposite the name of such Underwriter (except as otherwise provided
in the Pricing Agreement).
 
          (1) If the Company has elected not to rely upon Rule 430A under the
     1933 Act Regulations, the initial public offering price and the purchase
     price to be paid by the several Underwriters for the Securities, and the
     interest rate on the Securities, have each been determined and set forth in
     the Pricing Agreement, dated the date hereof, and an amendment to the
     Registration Statement and the Prospectus will be filed before the
     Registration Statement becomes effective.
 
          (2) If the Company has elected to rely upon Rule 430A under the 1933
     Act Regulations, the initial public offering price (which shall be a fixed
     price) and the purchase price to be paid by the several Underwriters for
     the Securities, and the interest rate on the Securities, shall be
     determined by agreement between the Representatives and the Company and,
     when so determined, shall be set forth in the Pricing Agreement. In the
     event that such prices and interest rate have not been agreed upon and the
     Pricing Agreement has not been executed and delivered by the parties
     thereto by the close of business on the fourteenth business day following
     the date of this Agreement, this Agreement shall terminate forthwith,
     without liability of any party to any other party, unless otherwise agreed
     to by the Company and the Representatives, except that Sections 6 and 7
     shall remain in effect.
 
     (b) Payment of the purchase price for, and delivery of certificates for,
the Securities shall be made at the office of Merrill Lynch & Co., North Tower,
World Financial Center, New York, New York 10281-1209, or at
 
                                        5
<PAGE>   6
 
such other place as shall be agreed upon by the Representatives and the Company,
at 10:00 A.M. on the third [fourth if priced after 4:30 p.m.] business day
(unless postponed in accordance with the provisions of Section 10) following the
date the Registration Statement becomes effective (or, if the Company has
elected to rely upon Rule 430A of the 1933 Act Regulations, the third [fourth]
business day after execution of the Pricing Agreement), or such other time not
later than ten business days after such date as shall be agreed upon by the
Representatives and the Company (such time and date of payment and delivery
being herein called "Closing Time"). Payment shall be made to the Company by
certified or official bank check or checks drawn in New York Clearing House
funds or similar next day funds payable to the order of the Company, against
delivery to the Representatives for the respective accounts of the Underwriters
of certificates for the Securities to be purchased by them. Certificates for the
Securities shall be in such denominations and registered in such names as the
Representatives may request in writing at least one business day before the
Closing Time. It is understood that each Underwriter has authorized the
Representatives, for its account, to accept delivery of, receipt for, and make
payment of the purchase price for, the Securities which it has agreed to
purchase. Merrill Lynch, individually and not as representative of the
Underwriters, may (but shall not be obligated to) make payment of the purchase
price for the Securities to be purchased by any Underwriter whose check has not
been received by the Closing Time, but such payment shall not relieve such
Underwriter from its obligations hereunder. The certificates for the Securities
will be made available for examination and packaging by the Representatives in
The City of New York not later than 3:00 P.M. on the last business day prior to
the Closing Time.
 
     SECTION 3.  Covenants of the Company.  The Company covenants with each
Underwriter as follows:
 
          (a) The Company will use its best efforts to cause the Registration
     Statement to become effective (as and when requested by the
     Representatives) and, if the Company elects to rely upon Rule 430A and
     subject to Section 3(b), will comply with the requirements of Rule 430A and
     will notify the Representatives immediately, and confirm the notice in
     writing, (i) when the Registration Statement, or any post-effective
     amendment to the Registration Statement, shall become effective, or any
     supplement to the Prospectus or any amended Prospectus shall have been
     filed, (ii) of the receipt of any comments from the Commission, (iii) of
     any request by the Commission for any amendment to the Registration
     Statement or any amendment or supplement to the Prospectus or for
     additional information, and (iv) of the issuance by the Commission of any
     stop order suspending the effectiveness of the Registration Statement or of
     any order preventing or suspending the use of any preliminary prospectus,
     or of the suspension of the qualification of the Securities for offering or
     sale in any jurisdiction, or of or the initiation or threatening of any
     proceedings for any of such purposes. The Company will make every
     reasonable effort to prevent the issuance of any stop order and, if any
     stop order is issued, to obtain the lifting thereof at the earliest
     possible moment. If the Company elects to rely on Rule 434 under the 1933
     Act Regulations, the Company will prepare an "abbreviated term sheet" that
     complies with the requirements of Rule 434 under the 1933 Act Regulations.
     If Company elects not to rely on Rule 434, the Company will provide the
     Underwriters with copies of the form of Prospectus, in such number as the
     Underwriters may reasonably request, and file or transmit for filing with
     the Commission such Prospectus in accordance with Rule 424(b) of the 1933
     Act by the close of business in New York on the business day immediately
     succeeding the date of the Pricing Agreement. If the Company elects to rely
     on Rule 434, the Company will provide the Underwriters with copies of the
     form of 434 Prospectus, in such number as the Underwriters may reasonably
     request, and file or transmit for filing with the Commission the form of
     Prospectus complying with Rule 434(c)(2) of the 1933 Act in accordance with
     Rule 424(b) of the 1933 Act by the close of business in New York on the
     business day immediately succeeding the date of the Pricing Agreement.
 
          (b) The Company will give the Representatives notice of its intention
     to file or prepare any amendment to the Registration Statement (including
     any post-effective amendment) or any amendment or supplement to the
     Prospectus, whether pursuant to the 1933 Act, the 1934 Act or otherwise,
     (including any revised prospectus which the Company proposes for use by the
     Underwriters in connection with the offering of the Securities which
     differs from the prospectus on file at the Commission at the time the
     Registration Statement first becomes effective, whether or not such revised
     prospectus is required to
 
                                        6
<PAGE>   7
 
     be filed pursuant to Rule 424(b) of the 1933 Act Regulations or any
     abbreviated term sheet prepared in reliance on Rule 434 of the 1933 Act
     Regulations), will furnish the Representatives with copies of any such
     amendment or supplement a reasonable amount of time prior to such proposed
     filing or use, as the case may be, and will not file any such amendment or
     supplement or use any such prospectus to which the Representatives or
     counsel for the Underwriters shall object.
 
          (c) The Company has furnished or will deliver to the Representatives
     and counsel for the Underwriters, without charge, signed copies of the
     Registration Statement as originally filed and of each amendment thereto
     (including exhibits filed therewith or incorporated by reference therein
     and documents incorporated or deemed to be incorporated by reference
     therein) and signed copies of all consents and certificates of experts, and
     will also deliver to the Representatives a conformed copy of the
     Registration Statement as originally filed and of each amendment thereto
     (without exhibits) for each of the Underwriters.
 
          (d) The Company will deliver to each Underwriter, without charge, from
     time to time until the effective date of the Registration Statement (or, if
     the Company has elected to rely upon Rule 430A, until such time the Pricing
     Agreement is executed and delivered), as many copies of each preliminary
     prospectus as such Underwriter may reasonably request, and the Company
     hereby consents to the use of such copies for purposes permitted by the
     1933 Act. The Company will furnish to each Underwriter, without charge,
     from time to time during the period when the Prospectus is required to be
     delivered under the 1933 Act or the 1934 Act, such number of copies of the
     Prospectus (as amended or supplemented) as such Underwriter may reasonably
     request for the purposes contemplated by the 1933 Act or the 1934 Act or
     the respective applicable rules and regulations of the Commission
     thereunder.
 
          (e) If any event shall occur or condition shall exist as a result of
     which it is necessary, in the opinion of counsel for the Underwriters or
     for the Company, to amend the Registration Statement or amend or supplement
     the Prospectus in order that the Prospectus will not include any untrue
     statements of a material fact or omit to state a material fact necessary in
     order to make the statements therein not misleading in the light of the
     circumstances existing at the time it is delivered to a purchaser, or if it
     shall be necessary, in the opinion of such counsel, at any such time to
     amend the Registration Statement or amend or supplement the Prospectus in
     order to comply with the requirements of the 1933 Act or the 1933 Act
     Regulations, the Company will promptly prepare and file with the
     Commission, subject to Section 3(b), such amendment or supplement as may be
     necessary to correct such statement or omission or to make the Registration
     Statement or the Prospectus comply with such requirements, and the Company
     will furnish to the Underwriters such number of copies of such amendment or
     supplement as the Underwriters may reasonably request.
 
          (f) If, at the time that the Registration Statement becomes effective,
     any information shall have been omitted therefrom in reliance upon Rule
     430A of the 1933 Act Regulations, then immediately following the execution
     of the Pricing Agreement, the Company will prepare, and file or transmit
     for filing with the Commission in accordance with such Rule 430A and Rule
     424(b) of the 1933 Act Regulations, copies of an amended Prospectus, or, if
     required by such Rule 430A, a post-effective amendment to the Registration
     Statement (including an amended Prospectus), containing all information so
     omitted and will use its best efforts to cause such post-effective
     amendment to be declared effective as promptly as practicable.
 
          (g) The Company will use its best efforts, in cooperation with the
     Underwriters, to qualify the Securities for offering and sale under the
     applicable securities laws of such states and other jurisdictions of the
     United States as the Representatives may designate and to maintain such
     qualifications in effect for a period of not less than one year from the
     effective date of the Registration Statement; provided, however, that the
     Company shall not be obligated to file any general consent to service of
     process or to qualify as a foreign corporation or as a dealer in securities
     in any jurisdiction in which it is not so qualified or to subject itself to
     taxation in respect of doing business in any jurisdiction in which it is
     not otherwise so subject. In each jurisdiction in which the Securities have
     been so qualified, the Company will file such
 
                                        7
<PAGE>   8
 
     statements and reports as may be required by the laws of such jurisdiction
     to continue such qualification in effect for a period of not less than one
     year from the effective date of the Registration Statement.
 
          (h) The Company will make generally available to its security holders
     as soon as practicable, but not later than 60 days after the close of the
     period covered thereby, an earnings statement (in form complying with the
     provisions of Rule 158 of the 1933 Act Regulations) covering a twelve month
     period beginning not later than the first day of the Company's fiscal
     quarter next following the "effective date" (as defined in said Rule 158)
     of the Registration Statement.
 
          (i) The Company will use the net proceeds received by it from the sale
     of the Securities in the manner specified in the Prospectus under "Use of
     Proceeds".
 
          (j) The Company, during the period when the Prospectus, is required to
     be delivered under the 1933 Act or the 1934 Act, will file all documents
     required to be filed with the Commission pursuant to the 1934 Act within
     the time periods required by the 1934 Act and the 1934 Act Regulations.
 
     SECTION 4.  Payment of Expenses.  The Company will pay all expenses
incident to the performance of its obligations under this Agreement, including
(i) the printing and filing of the Registration Statement as originally filed
and of each amendment thereto, (ii) the preparation, printing and delivery to
the Underwriters of this Agreement, the Pricing Agreement, any Agreement among
Underwriters, the Indenture and such other documents as may be required in
connection with the offering, purchase, sale and delivery of the Securities,
(iii) the preparation, issuance and delivery of the certificates for the
Securities to the Underwriters, (iv) the fees and disbursements of the Company's

including the abbreviated term sheet delivered by the Company pursuant to Rule
434 of the 1933 Act Regulations, (vii) the preparation, printing and delivery to
the Underwriters of copies of the Blue Sky Survey, any supplement thereto and
any Legal Investment Survey, (viii) the filing fees incident to, and the fees

terms of the sale of the Securities, (ix) the fees and expenses of the Trustee,
including the fees and disbursements of counsel for the Trustee, and (x) any
fees payable in connection with the rating of the Securities.
 
     If this Agreement is terminated by the Representatives in accordance with
the provisions of Section 5 or Section 9(a)(i) hereof, the Company shall
reimburse the Underwriters for all of their out-of-pocket expenses, including
the reasonable fees and disbursements of counsel for the Underwriters.
 
     SECTION 5.  Conditions of Underwriters' Obligations.  The obligations of
the several Underwriters hereunder are subject to the accuracy of the
representations and warranties of the Company herein contained, to the
performance by the Company of its obligations hereunder, and to the following
further conditions:
 
          (a) The Registration Statement shall have become effective not later
     than 5:30 P.M. on the date hereof, or with the consent of the
     Representatives, at a later time and date, not later, however, than 5:30

        Hopwood III, Esq., Senior Vice President and General Counsel of the
        Company, in form and substance satisfactory to counsel for the
        Underwriters, to the effect that:
 
                (i) The Company has been duly incorporated and is validly

           Company is as set forth in the Registration Statement under
           "Capitalization" (except for subsequent issuances, if any, pursuant
           to reservations or agreements referred to in the Prospectus), and the
           issued shares of capital stock of the Company have been duly
           authorized and validly issued and are fully paid and non-assessable
           (except as provided in Section 180.40(6) of the Wisconsin Business
           Corporation Law and judicial interpretations thereof).
 
                (v) The Securities have been duly authorized and executed, and
           when authenticated, issued and delivered in accordance with the
           Indenture, will constitute valid and legally binding obligations of
           the Company entitled to the benefits provided by the Indenture.
 
                (vi) The Indenture has been duly authorized, executed and
           delivered by the Company and constitutes a valid and legally binding
           instrument of the Company, enforceable in accordance with its terms,
           subject, as to enforcement, to bankruptcy, insolvency, reorganization
           and other laws of general applicability relating to or affecting
           creditors' rights and to general equity principles; and the Indenture
           has been duly qualified under the 1939 Act; and any taxes and fees
           required to be paid with respect to the issuance of the Securities
           have been paid.
 
                (vii) Each Principal Subsidiary of the Company (as designated in

           corporation in good standing under the laws of the jurisdiction of
           its incorporation, has corporate power and authority to own, lease

                (ix) The Registration Statement is effective under the 1933 Act
           and, to the best of his knowledge and information, no stop order
           suspending the effectiveness of the Registration Statement has been
           issued under the 1933 Act and remains outstanding and no proceedings
           therefor have been initiated or threatened by the Commission that
           have not been withdrawn.

                (x) As of their respective effective or issue dates, the
           Registration Statement, the Prospectus and each amendment or
           supplement to the Registration Statement and Prospectus (other than
           the financial statements, financial data and supporting schedules
           included therein, as to which no opinion need be rendered) complied
           as to form in all material respects with the requirements of the 1933
           Act and the 1933 Act Regulations; and nothing has come to his
           attention that would lead him to believe that the Registration
           Statement (other than the financial statements, financial data and
           supporting schedules included or incorporated by reference therein,
           as to which no opinion need be rendered), at the time it became
           effective or at the Representation Date, contained an untrue
           statement of a material fact or omitted to state a material fact
           required to be stated therein or necessary to make the statements
           therein not misleading, or that the Prospectus (other than the
           financial statements, financial data and supporting schedules
           included therein, as to which no opinion need be rendered), at the
           time the Registration Statement became effective (unless the term
           "Prospectus" refers to the Rule 424 prospectus, in which case at the
           time it was mailed or otherwise delivered to the Commission for
           filing) or at Closing Time, contained an untrue statement of a
           material fact or omitted to state a material fact necessary in order
           to make the statements therein, in the light of the circumstances
           under which they were made, not misleading.
 
                (xi) The Securities and the Indenture conform to the description
           thereof contained in the Registration Statement, and the form of
           certificates used to evidence the Securities is in due and proper
           form.
 
                (xii) To the best of his knowledge and information, there are no
           legal or governmental proceedings pending or threatened which are
           required to be disclosed in the Registration Statement, other than
           those disclosed therein and, to the best of his knowledge and
           information, all pending legal or governmental proceedings to which
           the Company or any subsidiary is a party or to which any of their
           property is subject which are not described in the Registration
           Statement, including ordinary, routine litigation incidental to the
           business, are, considered in the aggregate not material.
 
                (xiii) The information in the Registration Statement under
           "Description of Notes" to the extent that it constitutes matters of
           law or legal conclusions, has been reviewed by him and is correct.
 
                (xiv) To the best of his knowledge and information, there are no
           contracts, indentures, mortgages, loan agreements, notes, leases or
           other instruments required to be described or referred to in the
           Registration Statement or to be filed as exhibits thereto other than
           those described or referred to therein or filed or incorporated by
           reference as exhibits thereto, the descriptions thereof or references
           thereto are correct, and no default exists in the due performance or
           observance of any obligation, agreement, covenant or condition
           contained in any contract, indenture, mortgage, loan agreement, note,
           lease or other instrument so described or referred to therein, or
           filed or incorporated by reference, which default would have a
           material adverse effect on the condition, financial or otherwise, or
           the earnings, business affairs, or business prospects of the Company
           and its subsidiaries considered as one enterprise.
 
                (xv) No authorization, approval, consent or order of any court
           or governmental authority or agency is required in connection with
           the sale of the Securities to the Underwriters, except such as may be
           required under the 1933 Act, the 1933 Act Regulations, the 1939 Act
           or state securities laws; and, to the best of his knowledge and
           information, the execution and delivery of this Agreement, the
           compliance by the Company with all the provisions of the Securities
           and the Indenture and the consummation of the transactions
           contemplated herein will not conflict with, or constitute a breach of
           or default under, or result in the creation or imposition of any
           lien, charge or encumbrance upon, any property or assets of the
           Company or any of its subsidiaries, except as expressly contemplated
           in the Indenture, pursuant to, any contract, indenture, mortgage,
           loan agreement, note, lease or other instrument to which the Company
           or
 
                                       10
<PAGE>   11
 
           any of its subsidiaries is a party, or by which it or any of them may
           be bound, or to which any of the property or assets of the Company or
           any of its subsidiaries is subject, nor will such action result in
           any violation of the provisions of the charter or by-laws of the
           Company, or of any applicable law, administrative or court decree or
           administrative regulation.
 
                (xvi) The Company and its Principal Subsidiaries have good and
           marketable title in fee simple to all real property owned by them, in
           each case free and clear of all liens, encumbrances and defects
           except such as are described in the Prospectus or such as do not
           materially affect the value of such property and do not interfere
           with the use made and proposed to be made of such property by the
           Company and its Principal Subsidiaries; and any real property and
           buildings held under lease by the Company and its Principal
           Subsidiaries are held by them under valid, subsisting and enforceable
           leases with such exceptions as are not material and do not interfere
           with the use made and proposed to be made of such property and
           buildings by the Company and its Principal Subsidiaries (in giving
           the opinion in this clause (xvi), such counsel may state that no
           examination of record titles for the purpose of such opinion has been
           made, and that he is relying upon a general review of the titles of
           the Company and its Principal Subsidiaries, upon opinions of local
           counsel and abstracts, reports and policies of title companies
           rendered or issued at or subsequent to the time of acquisition of
           such property by the Company or its Principal Subsidiaries, upon
           opinions of counsel to the lessors of such property and, in respect
           of matters of fact, upon certificates of officers of the Company or
           its Principal Subsidiaries, provided that such counsel shall state
           that he believes that both you and he are justified in relying upon
           such opinions, abstracts, reports, policies and certificates).
 
                (xvii) The documents incorporated by reference in the Prospectus
           (other than the financial statements, financial data and supporting
           schedules included therein, as to which no opinion need be rendered),
           when they were filed with the Commission, complied as to form in all
           material respects with the requirements of the 1934 Act and the rules
           and regulations of the Commission thereunder; and he has no reason to
           believe that any of such documents, when such documents were so
           filed, contained an untrue statement of a material fact or omitted to
           state a material fact necessary in order to make the statements
           therein, in the light of the circumstances under which they were made
           when such documents were so filed, not misleading.
 
             In giving his opinion, Howard H. Hopwood III, Esq. may rely as to
        matters of New York law upon the opinion of Brown & Wood.
 
             (2) The favorable opinion, dated as of Closing Time, of Brown &
        Wood, counsel for the Underwriters, with respect to the matters set
        forth in (i), (v), (vi) and (viii) to (xi) and (xiii), inclusive, of
        subsection (b) (1) of this Section.
 
             In giving their opinion, Brown & Wood may rely as to matters of
        Wisconsin law upon the opinion of Howard H. Hopwood III, Esq.
 
          (c) At Closing Time there shall not have been, since the respective
     dates as of which information is given in the Registration Statement and
     the Prospectus, any material adverse change in the condition, financial or
     otherwise, or in the earnings, business affairs or business prospects of
     the Company and its subsidiaries considered as one enterprise, whether or
     not arising in the ordinary course of business, and you shall have received
     a certificate of the President or a Vice President of the Company, dated as
     of Closing Time, to the effect that (i) there has been no such material
     adverse change, (ii) the representations and warranties in Section 1 are
     true and correct with the same force and effect as though expressly made at
     and as of Closing Time, (iii) the Company has complied with all agreements
     and satisfied all conditions on its part to be performed or satisfied at or
     prior to Closing Time, and (iv) no stop order suspending the effectiveness
     of the Registration Statement under the 1933 Act has been issued and
     remains outstanding and no proceedings for that purpose have been initiated
     or threatened by the Commission and not withdrawn.

          (d) At the time of the execution of this Agreement, you shall have
     received from KPMG Peat Marwick LLP a letter dated such date, in form and
     substance satisfactory to you, to the effect that (i) they are independent
     public accountants with respect to the Company and its subsidiaries within
     the meaning of the 1933 Act and 1934 Act and the applicable published rules
     and regulations thereunder and no information concerning their relationship
     with or interest in the Company is required by Item 10 of the Registration
     Statement; (ii) it is their opinion that the consolidated financial
     statements and supporting schedules included or incorporated by reference
     in the Registration Statement and covered by their opinions incorporated
     therein comply as to form in all material respects with the applicable
     accounting requirements of the 1933 Act and 1934 Act and the applicable
     published rules and regulations thereunder; (iii) based upon limited
     procedures set forth in detail in such letter (which shall include, without
     limitation, the procedures specified by the American Institute of Certified
     Public Accountants for a review of interim financial information as
     described in SAS No. 71, Interim Financial Information, with respect to the
     unaudited condensed consolidated financial statement of the Company and its
     subsidiaries included by reference in the Registration Statement), nothing
     has come to their attention which causes them to believe that (A) the
     unaudited consolidated financial statements and supporting schedules of the
     Company and its subsidiaries included or incorporated by reference in the
     Registration Statement do not comply as to form in all material respects
     with the applicable accounting requirements of the 1933 Act and 1934 Act
     and the applicable published rules and regulations thereunder or are not
     presented in conformity with generally accepted accounting principles
     applied on a basis substantially consistent with that of the audited
     consolidated financial statements included in the Registration Statement,
     (B) the unaudited amounts of net interest revenues, net income and net
     income per common share set forth following "Selected Consolidated
     Financial Data" in the Prospectus were not determined on a basis
     substantially consistent with that used in determining the corresponding
     amounts in the audited consolidated financial statements included or
     incorporated by reference in the Registration Statement, or (C) at a
     specified date not more than three days prior to the date of this
     Agreement, there has been any change in the preferred stock or common stock
     of the Company or any increase in the consolidated long term debt of the
     Company and its subsidiaries or any decrease in consolidated stockholders'
     equity as compared with the amounts shown in the [  ], 1995 consolidated
     balance sheet included in the Registration Statement or, during the period
     from [          ], 1995 to a specified date not more than three days prior
     to the date of this Agreement, there were any decreases, as compared with
     the corresponding period in the preceding year, in consolidated net income
     or net income per common share of the Company and its subsidiaries, except
     in all instances for changes, increases or decreases which the Registration
     Statement and the Prospectus disclose have occurred or may occur, and (iv)
     in addition to the examination referred to in their opinions and the
     limited procedures referred to in clause (iii) above, they have carried out
     certain specified procedures, not constituting an audit, with respect to
     certain amounts, percentages and financial information which are included
     or incorporated in the Registration Statement and Prospectus and which are
     specified by you, and have found such amounts, percentages and financial
     information to be in agreement with the relevant accounting, financial and
     other records of the Company and its subsidiaries identified in such
     letter.
 
          (e) At Closing Time the Representatives shall have received from KPMG
     Peat Marwick LLP a letter, dated as of Closing Time, to the effect that
     they reaffirm the statements made in the letter furnished pursuant to
     subsection (d) of this Section, except that the specified date referred to
     shall be a date not more than three days prior to Closing Time and, if the
     Company has elected to rely on Rule 430A of the 1933 Act Regulations, to
     the further effect that they have carried out procedures as specified in
     clause (iv) of subsection (d) of this Section with respect to certain
     amounts, percentages and financial information specified by the
     Representatives and deemed to be a part of the Registration Statement
     pursuant to Rule 430(A)(b) and have found such amounts, percentages and
     financial information to be in agreement with the records specified in such
     clause (iv).
 
          (f) At Closing Time, you shall have received from KPMG Peat Marwick
     LLP a letter, dated as of Closing Time, to the effect that it is their
     opinion that the consolidated financial statements and supporting schedules
     of First Colonial and its subsidiaries incorporated by reference in the
     Registration Statement and covered by their opinions therein comply as to
     form in all material respects with the
 
                                       12
<PAGE>   13
 
     applicable accounting requirements of the 1933 Act and 1934 Act and the
     applicable published rules and regulations thereunder.
 
          (g) At the Closing Time, the NASD shall have approved in writing the
     Underwriters' participation in the distribution of the Securities and such
     approval shall not have been withdrawn or limited.
 
          (h) At Closing Time, the Securities shall be rated at least [     ] by
     Moody's Investor's Service Inc. and [     ] by Standard & Poor's Company [,
     and the Company shall have delivered to the Representatives a letter dated
     the Closing Time, from each such rating agency, or other evidence
     satisfactory to the Representatives, confirming that the Securities have
     such ratings; and] since the date of this Agreement, there shall not have
     occurred a downgrading in the rating assigned to the Securities or any of
     the Company's other securities.
 
          (i) At Closing Time, counsel for the Underwriters shall have been
     furnished with such documents and opinions as they may require for the
     purpose of enabling them to pass upon the issuance and sale of the
     Securities as herein contemplated and related proceedings, or in order to
     evidence the accuracy of any of the representations or warranties, or the
     fulfillment of any of the conditions, herein contained; and all proceedings
     taken by the Company in connection with the issuance and sale of the
     Securities as herein contemplated shall be satisfactory in form and
     substance to the Representatives and counsel for the Underwriters.
 
     If any condition specified in this Section shall not have been fulfilled
when and as required to be fulfilled, this Agreement may be terminated by the
Representatives by notice to the Company at any time at or prior to Closing
Time, and such termination shall be without liability of any party to any other
party except as provided in Section 4 and except that Sections 6 and 7 shall
survive any such termination and remain in full force and effect.
 
     SECTION 6.  Indemnification.
 
     (a) The Company agrees to indemnify and hold harmless each Underwriter and
each person, if any, who controls any Underwriter within the meaning of Section

          (i) against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of any untrue statement or alleged
     untrue statement of a material fact contained in the Registration Statement
     (or any amendment thereto), including the information deemed to be part of
     the Registration Statement pursuant to Rule 430A(b) or Rule 434 of the 1933
     Act Regulations, if applicable, or the omission or alleged omission
     therefrom of a material fact required to be stated therein or necessary to
     make the statements therein not misleading or arising out of any untrue
     statement or alleged untrue statement of a material fact contained in any
     preliminary prospectus or prospectus, including the Prospectus (or any
     amendment or supplement thereto), or the omission or alleged omission
     therefrom of a material fact necessary in order to make the statements
     therein, in the light of the circumstances under which they were made, not
     misleading;
 
          (ii) against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission; provided that (subject to Section
     6(d) below) any such settlement is effected with the written consent of the
     Company; and
 
          (iii) against any and all expense whatsoever, as incurred (including,

     extent that any such expense is not paid under (i) or (ii) above;
 
                                       13
<PAGE>   14
 
provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by any
Underwriter through the Representatives expressly for use in the Registration
Statement (or any amendment thereto) or any preliminary prospectus or the
Prospectus (or any amendment or supplement thereto).
 
     (b) Each Underwriter severally agrees to indemnify and hold harmless the
Company, its directors, each of its officers who signed the Registration
Statement, and each person, if any, who controls the Company within the meaning
of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all
loss, liability, claim, damage and expense described in the indemnity contained
in subsection (a) of this Section, as incurred, but only with respect to untrue
statements or omissions, or alleged untrue statements or omissions, made in the
Registration Statement (or any amendment thereto) or any preliminary prospectus
or the Prospectus (or any amendment or supplement thereto) in reliance upon and
in conformity with written information furnished to the Company by such
Underwriter through the Representatives expressly for use in the Registration
Statement (or any amendment thereto) or such preliminary prospectus or the
Prospectus (or any amendment or supplement thereto).
 
     (c) Each indemnified party shall give notice as promptly as reasonably
practicable to each indemnifying party of any action commenced against it in
respect of which indemnity may be sought hereunder, but failure to so notify an
indemnifying party shall not relieve such indemnifying party from any liability
which it may have otherwise than on account of this indemnity agreement. An
indemnifying party may participate at its own expense in the defense of any such
action; provided, however, that counsel to the indemnifying party shall not
(except with the consent of the indemnified party) be counsel to the indemnified
party. In no event shall the indemnifying parties be liable for fees and
expenses of more than one counsel (in addition to any local counsel) separate
from their own counsel for all indemnified parties in connection with any one
action or separate but similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances. No indemnifying
party shall, without the prior written consent of the indemnified parties,
settle or compromise or consent to the entry of any judgment with respect to any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever in respect of which
indemnification or contribution could be sought under this Section 6 or Section
7 hereof (whether or not the indemnified parties are actual or potential parties
thereto), unless such settlement, compromise or consent (i) includes an
unconditional release of each indemnified party from all liability arising out
of such litigation, investigation, proceeding or claim and (ii) does not include
a statement as to or an admission of fault, culpability or a failure to act by
or on behalf of any indemnified party.
 
     (d) If at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 6(a)(ii) effected without its
written consent if (i) such settlement is entered into more than 45 days after
receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement at
least 30 days prior to such settlement being entered into and (iii) such
indemnifying party shall not have reimbursed such indemnified party in
accordance with such request prior to the date of such settlement.
 
     (e) For purposes of this Section 6, all references to the Registration
Statement, any preliminary prospectus or the Prospectus, or any amendment or
supplement to any of the foregoing, shall be deemed to include, without
limitation, any electronically transmitted copies thereof, including, without
limitation, any copies filed with the Commission pursuant to EDGAR.
 
     SECTION 7.  Contribution.  If the indemnification provided for in Section 6
hereof is for any reason unavailable to or insufficient to hold harmless an
indemnified party in respect of any losses, liabilities, claims, damages or
expenses referred to therein, then each indemnifying party shall contribute to
the aggregate amount of such losses, liabilities, claims, damages and expenses
incurred by such indemnified party, as incurred, (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 hand from the offering of the Securities
pursuant to this Agreement or (ii) if the allocation provided by clause (i) is
not permitted by applicable law, in such
 
                                       14
<PAGE>   15
 
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but also the relative fault of the Company on the one
hand and of the Underwriters on the other hand in connection with the statements
or omissions which resulted in such losses, liabilities, claims, damages or
expenses, 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 hand in connection with the offering of the Securities pursuant to this
Agreement shall be deemed to be in the same respective proportions as the total
net proceeds from the offering of the Securities pursuant to this Agreement
(before deducting expenses) received by the Company and the total underwriting
discount received by the Underwriters, in each case as set forth on the cover of
the Prospectus, bear to the aggregate initial public offering price of the
Securities as set forth on such cover. The relative fault of the Company on the
one hand and the Underwriters on the other hand shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or by the Underwriters and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The Company and the Underwriters
agree that it would not be just and equitable if contribution pursuant to this
Section 7 were determined by pro rata allocation (even if the Underwriters were
treated as one entity for such purpose) or by any other method of allocation
which does not take account of the equitable considerations referred to above in
this Section 7. The aggregate amount of losses, liabilities, claims, damages and
expenses incurred by an indemnified party and referred to above in this Section
7 shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.
Notwithstanding the provisions of this Section 7, 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 1933
Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation. For purposes of this Section 7, each person,
if any, who controls an Underwriter within the meaning of Section 15 of the 1933
Act or Section 20 of the 1934 Act shall have the same rights to contribution as
such Underwriter, and each director of the Company, each officer of the Company
who signed the Registration Statement, and each person, if any, who controls the
Company within the meaning of Section 15 of the 1933 Act or Section 20 of the
1934 Act shall have the same rights to contribution as the Company. The
Underwriters' respective obligations to contribute pursuant to this Section 7
are several in proportion to the principal amount of Securities set forth
opposite their respective names in Schedule A hereto and not joint.
 
     SECTION 8.  Representations, Warranties and Agreements to Survive
Delivery.  All representations, warranties and agreements contained in this
Agreement and the Pricing Agreement, or contained in certificates of officers of
the Company submitted pursuant hereto, shall remain operative and in full force
and effect, regardless of any investigation made by or on behalf of any
Underwriter or controlling person, or by or on behalf of the Company, and shall
survive delivery of the Securities to the Underwriters.
 
     SECTION 9.  Termination of Agreement.
 
     (a) The Representatives may terminate this Agreement, by notice to the
Company, at any time at or prior to Closing Time (i) if there has been, since
the time of execution of this Agreement or since the respective dates as of
which information is given in the Prospectus, any material adverse change in the
condition, financial or otherwise, or in the earnings, business affairs or
business prospects of the Company and its subsidiaries considered as one
enterprise, whether or not arising in the ordinary course of business, or (ii)
if there has occurred any material adverse change in the financial markets in
the United States or elsewhere, any outbreak of hostilities or escalation
thereof or other calamity or crisis or any change or development involving a
prospective change in national or international political, financial or economic
conditions, in each case the effect of which is such as to make it, in the
judgment of the Representatives, impracticable to market the Securities or to
enforce contracts for the sale of the Securities, or (iii) if trading in the
Securities has been
 
                                       15
<PAGE>   16
 
suspended or limited by the Commission or if trading generally on the American
Stock Exchange or the New York Stock Exchange or in the over-the-counter market
has been suspended or limited, or minimum or maximum prices for trading have
been fixed, or maximum ranges for prices have been required, by any of said
exchanges or by such system or by order of the Commission, the National
Association of Securities Dealers, Inc. or any other governmental authority, or
(iv) if a banking moratorium has been declared by either Federal, New York or
Wisconsin authorities. As used in this Section 9(a), the term "Prospectus" means
the Prospectus in the form first used by the Underwriters to confirm sales of
the Securities.
 
     (b) If this Agreement is terminated pursuant to this Section, such
termination shall be without liability of any party to any other party except as
provided in Section 4 hereof, and provided further that Sections 3(l), 6 and 7
shall survive such termination and remain in full force and effect.
 
     SECTION 10.  Default by One or More of the Underwriters.  If one or more of
the Underwriters shall fail at Closing Time to purchase the Securities which it
or they are obligated to purchase under this Agreement and the Pricing Agreement
(the "Defaulted Securities"), the Representatives shall have the right, within
24 hours thereafter, to make arrangements for one or more of the non-defaulting
Underwriters, or any other underwriters, to purchase all, but not less than all,
of the Defaulted Securities in such amounts as may be agreed upon and upon the
terms herein set forth; if, however, the Representatives shall not have
completed such arrangements within such 24-hour period, then:
 
          (a) if the number of Defaulted Securities does not exceed 10% of the
     aggregate principal amount of the Securities, each of the non-defaulting
     Underwriters shall be obligated, severally and not jointly, to purchase the
     full amount thereof in the proportions that their respective underwriting
     obligations hereunder bear to the underwriting obligations of all
     non-defaulting Underwriters, or
 
          (b) if the number of Defaulted Securities exceeds 10% of the aggregate
     principal amount of the Securities, this Agreement shall terminate without
     liability on the part of any non-defaulting Underwriter.
 
     No action taken pursuant to this Section shall relieve any defaulting
Underwriter from liability in respect of its default.
 
     In the event of any such default which does not result in a termination of
this Agreement, either the Representatives or the Company shall have the right
to postpone Closing Time for a period not exceeding seven days in order to
effect any required changes in the Registration Statement or Prospectus or in
any other documents or arrangements. As used herein, the term "Underwriter"
includes any person substituted for an Underwriter under this Section 10.
 
     SECTION 11.  Notices.  All notices and other communications hereunder shall
be in writing and shall be deemed to have been duly given if mailed or
transmitted by any standard form of telecommunication. Notices to the
Underwriters shall be directed to the Representatives at North Tower, World
Financial Center, New York, New York 10281-1201 attention of Henry Michaels;
notices to the Company shall be directed to it at [  ], attention of [  ].
 
     SECTION 12.  Parties.  This Agreement and the Pricing Agreement shall each
inure to the benefit of and be binding upon the Underwriters and the Company and
their respective successors. Nothing expressed or mentioned in this Agreement or
the Pricing Agreement is intended or shall be construed to give any person, firm
or corporation, other than the Underwriters and the Company and their respective
successors and the controlling persons and officers and directors referred to in
Sections 6 and 7 and their heirs and legal representatives, any legal or
equitable right, remedy or claim under or in respect of this Agreement or the
Pricing Agreement or any provision herein or therein contained. This Agreement
and the Pricing Agreement and all conditions and provisions hereof and thereof
are intended to be for the sole and exclusive benefit of the Underwriters and
the Company and their respective successors, and said controlling persons and
officers and directors and their heirs and legal representatives, and for the
benefit of no other person, firm or corporation. No purchaser of Securities from
any Underwriter shall be deemed to be a successor by reason merely of such
purchase.

     SECTION 13.  GOVERNING LAW AND TIME.  THIS AGREEMENT AND THE PRICING
AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SAID
STATE. EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW

instrument, along with all counterparts, will become a binding agreement between

depositary reasonably acceptable to the Company, wherever situated, if such
certificate shall be deemed by the Trustee to be satisfactory, showing that at

Bearer Security continues until (1) another certificate or affidavit bearing a
later date issued in respect of the same Bearer Security is produced, or (2)
such Bearer Security is produced to the Trustee by some other Person, or (3)
such Bearer Security is surrendered in exchange for a Registered Security, or
(4) such Bearer Security is no longer Outstanding. The principal amount and

direction, notice, consent, waiver or other Act may be given before or after
such record date, but only the Holders of Registered Securities of

such record date; provided that no such authorization, agreement or consent by
the Holders of Registered Securities on such record date shall be deemed
effective unless it shall become effective pursuant to the provisions of this
Indenture not later than six months after the record date.

or other action by the Holder of any Security shall bind every future Holder of
the same Security and the Holder of every Security issued upon the registration
of transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done or suffered to be done by the Trustee, any Security Registrar, any
Paying Agent or the Company in reliance thereon, whether or not notation of such
action is made upon such Security.

     address previously furnished in writing to the Trustee by the Company.
 
     Section 106.  Notice to Holders; Waiver.
 
     Except as otherwise expressly provided herein or in any Security, where
this Indenture provides for notice to Holders of any event,
 
          (1) such notice shall be sufficiently given to Holders of Registered
     Securities if in writing and mailed, first-class postage prepaid, to each
     Holder of a Registered Security affected by such event, at his address as
     it appears in the Security Register, not later than the latest date, and
     not earlier than the earliest date, prescribed for the giving of such
     Notice; and
 
          (2) such notice shall be sufficiently given to Holders of Bearer
     Securities, if any, if published in an Authorized Newspaper in The City of
     New York and, if such Securities are then listed on any stock exchange
     outside the United States, in an Authorized Newspaper in such city as the
     Company shall advise the Trustee that such stock exchange so requires, on a
     Business Day at least twice, the first such publication to be not earlier
     than the earliest date and not later than the latest date prescribed for
     the giving of such notice.
 
     In any case where notice to Holders of Registered Securities is given by
mail, neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder of a Registered Security shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice to Holders of Bearer Securities
given as provided herein. Any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given or provided. In
the 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.
 
     In case by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder.

Neither failure to give notice by publication to Holders of Bearer Securities as
provided above, nor any defect in any notice so published, shall affect the
sufficiency of any notice mailed to Holders of Registered Securities as provided
above.
 
     Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders shall be filed with the Trustee, but such filing
shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.
 
     Section 107.  Language of Notices.
 
     Any request, demand, authorization, direction, notice, consent, election or
waiver required or permitted under this Indenture shall be in the English
language, except that, if the Company so elects, any published notice may be in
an official language of the country of publication.
 
     Section 108.  Conflict with Trust Indenture Act.
 
     If any provision hereof limits, qualifies or conflicts with the duties
imposed by Sections 310 through 317 of the Trust Indenture Act by operation of
Section 318(c) thereof, such imposed duties shall control.
 
     Section 109.  Effect of Headings and Table of Contents.
 
     The Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.
 
     Section 110.  Successors and Assigns.
 
     All covenants and agreements in this Indenture by the Company shall bind
its successors and assigns, whether so expressed or not.
 
     Section 111.  Separability Clause.
 
     In case any provision in this Indenture, any Security or any Coupon 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 112.  Benefits of Indenture.
 
     Nothing in this Indenture, any Security or any Coupon, express or implied,
shall give to any Person, other than the parties hereto, any Security Registrar,
any Paying Agent and their successors hereunder, the Holders of Securities or
Coupons, and, to the extent, but only to the extent, provided in Section 1503,
the holders of Senior Indebtedness any benefit or any legal or equitable right,
remedy or claim under this Indenture.
 
     Section 113.  Governing Law.
 
     This Indenture, the Securities and the Coupons shall be governed by and
construed in accordance with the laws of the State of New York applicable to
agreements made or instruments entered into and, in each case, performed in said
state.
 
     Section 114.  Legal Holidays.
 
     In any case where any Interest Payment Date, Redemption Date, repayment
date pursuant to Section 1301 therein or Stated Maturity of any Security, or the
last date on which a Holder has the right to convert his Securities, shall not
be a Business Day at any Place of Payment, then (notwithstanding any other
provision of this Indenture, any Security or Coupon other than a provision in
any Security or any Coupon that specifically states that such provision shall
apply in lieu of this Section) payment of interest or any Additional Amounts or
principal (and premium, if any) or conversion of the Securities need not be made
at such Place of Payment on such date, but may be made on the next succeeding
Business Day at such Place of Payment with the same force and effect as if made
on the Interest Payment Date or Redemption Date, or at the Stated Maturity, or
on such last date for conversion, and no interest shall accrue on the amount so
payable for the period from and after such Interest Payment Date, Redemption
Date or Stated Maturity, as the case may be.

     Section 201.  Forms Generally.

issued pursuant to this Indenture shall be in the form established by or

     Section 203.  Securities in Global Form.
 
     If Securities of a series are issuable in global form any such Security may
provide that it shall represent the aggregate amount of Outstanding Securities
of such series from time to time endorsed thereon and may also provide that the
aggregate amount of Outstanding Securities represented thereby may from time to
time be increased or reduced to reflect exchanges. Any endorsement of any
Security in global form to reflect the amount, or any increase or decrease in
the amount, or changes in the rights of Holders, of Outstanding Securities
represented thereby shall be made in such manner and by such Person or Persons
as shall be specified therein or in the Company Order to be delivered pursuant
to Section 303 with respect thereto. Subject to the provisions of Section 303
the Trustee shall deliver and redeliver any Security in permanent global form in
the manner and upon instructions given by the Person or Persons specified
therein or in the applicable Company Order. If a Company Order pursuant to
Section 303 has been, or simultaneously is, delivered, any instructions by the
Company with respect to a Security in global form shall be in writing but need
not comply with Section 102 and need not be accompanied by an Opinion of
Counsel.
 
     The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Security in global form if such Security was never
issued and sold by the Company and the Company delivers to the Trustee the
Security in global form together with written instructions (which need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 303.
 
     Notwithstanding the provisions of Section 307, unless otherwise specified
as contemplated by Section 301, payment of principal of and any premium and
interest on any Security in permanent global form shall be made to the Person or
Persons specified therein.

     Notwithstanding the provisions of Section 308 and except as provided in the
preceding paragraph, the Company, the Trustee and any agent of the Company and
the Trustee shall treat as the Holder of such principal amount of Outstanding
Securities represented by a permanent global Security (i) in the case of a
permanent global Security in registered form, the Holder of such permanent
global Security in registered form, or (ii) in the case of a permanent global
Security in bearer form, the Person or Persons specified pursuant to Section
301.

these officers on the Securities and any Coupons appertaining thereto may be

     Securities and Coupons bearing the manual or facsimile signatures of

<PAGE>   22
 
     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series, together with any
Coupons appertaining thereto, executed by the Company, to the Trustee for
authentication, and, provided that the Board Resolution or Resolutions and
Officers' Certificate or supplemental indenture or indentures with respect to
such Securities referred to in Section 301 and a Company Order for the
authentication and delivery of such Securities, has been delivered to the
Trustee, the Trustee in accordance with the Company Order and subject to the
provisions hereof shall authenticate and deliver such Securities. In
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities and any Coupons appertaining
thereto, the Trustee shall be entitled to receive, and (subject to Sections
315(a) through 315(d) of the Trust Indenture Act) shall be fully protected in
relying upon,
 
        (i) an Opinion of Counsel stating, to the effect
 
             (a) that the form or forms and terms, or the manner of determining
        such terms, of such Securities and Coupons, if any, have been
        established in conformity with the provisions of this Indenture;
 
             (b) that all conditions precedent to the authentication and
        delivery of such Securities and Coupons, if any, appertaining thereto,
        have been complied with and that such Securities, and Coupons, when
        completed by appropriate insertion and executed and delivered by the
        Company to the Trustee for authentication pursuant to this Indenture,
        and 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 legally valid and binding obligations of the
        Company, enforceable against the Company in accordance with their terms,
        subject to bankruptcy, insolvency, reorganization, moratorium,
        fraudulent transfer or other similar laws affecting the enforcement of
        creditors' rights generally, and subject to general principles of equity
        (regardless of whether enforcement is sought in a proceeding in equity
        or at law) and will entitle the Holders thereof to the benefits of the
        Indenture; such Opinion of Counsel need express no opinion as to the
        availability of equitable remedies;
 
             (c) that all laws and requirements in respect of the execution and
        delivery by the Company of such Securities and Coupons, if any, have
        been complied with; and
 
             (d) as to such other matters as the Trustee may reasonably request;
        and
 
          (ii) an Officers' Certificate stating that, to the best knowledge of
     the Persons executing such certificate, no Default with respect to any of
     the Securities shall have occurred and be continuing.
 
     If all the Securities of any series are not to be issued at one time, it
shall not be necessary to deliver an Opinion of Counsel and an Officers'
Certificate at the time of issuance of each Security, but such opinion and
certificate, with appropriate modifications, shall be delivered at or before the
time of issuance of the first Security of such series.
 
     The Trustee shall not be required to authenticate or to cause an
Authenticating Agent to authenticate any 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 or if the Trustee,
being advised in writing by counsel, determines that such action may not
lawfully be taken.
 
     Each Registered Security shall be dated the date of its authentication.
Each Bearer Security and any temporary Bearer Security in global form shall be
dated as of the date specified as contemplated by Section 301.
 
     No Security or Coupon 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 in
Section 202 or 611 executed by or on behalf of the Trustee by the manual
signature of one of its authorized officers, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder. Except as permitted by
 
                                       15
<PAGE>   23
 
Section 306 or 307, the Trustee shall not authenticate and deliver any Bearer
Security unless all appurtenant Coupons for interest then matured have been
detached and cancelled.
 
     Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder to the Company, or any Person acting on
its behalf, but shall never have been 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 hereof.
 
     Section 304.  Temporary Securities.
 
     Pending the preparation of definitive Securities of any series, the Company
may execute and deliver to the Trustee and, upon Company Order the Trustee shall
authenticate and deliver, in the manner provided in Section 303, temporary
Securities of such series 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, in registered form or, if authorized, in bearer form with one or
more Coupons or without Coupons and with such appropriate insertions, omissions,
substitutions and other variations as the officers of the Company executing such
Securities may determine, as conclusively evidenced by their execution of such
Securities. In the case of Securities of any series, such temporary Securities
may be in global form.
 
     Except in the case of temporary Securities in global form, which shall be
exchanged in accordance with the provisions thereof, if temporary Securities of
any series are issued, the Company shall cause definitive Securities of such
series to be prepared without unreasonable delay. After the preparation of
definitive Securities of any Series, the temporary Securities of such series, if
any, shall be exchangeable upon request for definitive Securities of such series
containing identical terms and provisions upon surrender of the temporary
Securities of such series at an office or agency of the Company maintained for
such purpose pursuant to Section 1002, without charge to any Holder. Upon
surrender for cancellation of any one or more temporary Securities of any series
(accompanied by any unmatured Coupons appertaining thereto), the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
like principal amount of definitive Securities of authorized denominations of
the same series containing identical terms and provisions; provided, however,
that no definitive Bearer Security, except as provided pursuant to Section 301,
shall be delivered in exchange for a temporary Registered Security; and
provided, further, that a definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security only in compliance with the conditions
set forth herein or therein. Unless otherwise specified as contemplated by
Section 301 with respect to a temporary global Security, 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.
 
     Section 305.  Registration, Transfer and Exchange.
 
     With respect to the Registered Securities of each series, if any, the
Company shall cause to be kept, at an office or agency of the Company maintained
pursuant to Section 1002, a register (each such register being herein sometimes
referred to as the "Security Register") in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration
of the Registered Securities of each series and of transfers of the Registered
Securities of such series. In the event that the Trustee shall not be the
Security Registrar, it shall have the right to examine the Security Register at
all reasonable times. [Name of Security Registrar] is hereby initially appointed
as Security Registrar for each series of Securities.
 
     Upon surrender for registration of transfer of any Registered Security of
any series at any office or agency of the Company maintained for that series
pursuant to Section 1002, the Company shall execute, and the Trustee shall
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Registered Securities of the same series of any
authorized denominations, of a like aggregate principal amount bearing a number
not contemporaneously outstanding and containing identical terms and provisions.
 
                                       16
<PAGE>   24
 
     At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series containing
identical terms and provisions, in any authorized denominations, and of a like
aggregate principal amount, upon surrender of the Securities to be exchanged at
any such office or agency. Whenever any Registered Securities are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Registered Securities which the Holder making the exchange is
entitled to receive.
 
     If specified as contemplated by Section 301 with respect to Securities of
any series, at the option of the Holder, Bearer Securities of such series may be
exchanged for Registered Securities of such series containing identical terms
and provisions, of any authorized denominations and aggregate principal amount,
upon surrender of the Bearer Securities to be exchanged at any such office or
agency for such series, with all unmatured Coupons and all matured Coupons in
default thereto appertaining. If the Holder of a Bearer Security is unable to
produce any such unmatured Coupon or Coupons or matured Coupon or Coupons in
default, such exchange may be effected if the Bearer Securities are accompanied
by payment in funds acceptable to the Company and the Trustee in an amount equal
to the face amount of such missing Coupon or Coupons, or the surrender of such
missing Coupon or Coupons may be waived by the Company and the Trustee if there
is furnished to them such security or indemnity as they may require to save each
of them and any Paying Agent harmless. If thereafter the Holder of such Security
shall surrender to any Paying Agent any such missing Coupon in respect of which
such a payment shall have been made, such Holder shall be entitled to receive
the amount of such payment; provided, however, that, except as otherwise
provided in Section 1002, interest represented by Coupons shall be payable only
upon presentation and surrender of those Coupons at an office or agency for such
series located outside the United States. Notwithstanding the foregoing, in case
a Bearer Security of any series is surrendered at any such office or agency in
exchange for a Registered Security of such series and like tenor after the close
of business at such office or agency on (i) any Regular Record Date and before
the opening of business at such office or agency on the relevant Interest
Payment Date, or (ii) any Special Record Date and before the opening of business
at such office or agency on the related date for payment of Defaulted Interest,
such Bearer Security shall be surrendered without the Coupon relating to such
Interest Payment Date or proposed date of payment, as the case may be (or, if
such Coupon is so surrendered with such Bearer Security, such Coupon shall be
returned to the person so surrendering the Bearer Security), and interest or
Defaulted Interest, as the case may be, will not be payable on such Interest
Payment Date or proposed date for payment, as the case may be, in respect of the
Registered Security issued in exchange for such Bearer Security, but will be
payable only to the Holder of such Coupon when due in accordance with the
provisions of this Indenture.
 
     If specified as contemplated by Section 301 with respect to Securities of
any series, at the option of the Holder, Registered Securities of such series
may be exchanged for Bearer Securities upon such terms and conditions as may be
provided pursuant hereto with respect to such series.
 
     Whenever any Securities are so surrendered for exchange as contemplated by
the immediately preceding two paragraphs, the Company shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive.
 
     Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any global Security of any series shall be
exchangeable for Securities of such series only if (i) the Depository is at any
time unwilling or unable or ineligible to continue as Depository and a successor
depository is not appointed by the Company within 60 days of the date the
Company is so notified in writing, (ii) the Company executes and delivers to the
Trustee a Company Order to the effect that such global Security shall be so
exchangeable, or (iii) a Default has occurred and is continuing with respect to
the Securities. If the beneficial owners of interests in a global Security are
entitled to exchange such interests for Securities of such series and of like
tenor and principal amount of any authorized form and denomination, as specified
as contemplated by Section 301, then without unnecessary delay but in any event
not later than the earliest date on which such interests may be so exchanged,
the Company shall deliver to the Trustee definitive Securities of that series in
aggregate principal amount equal to the principal amount of such global
Security, executed by the Company. On or after the earliest date on which such
interests may be so exchanged, such global Security shall be surrendered from
time to time by the U.S. Depository or such other depository as shall be
specified in the
 
                                       17
<PAGE>   25
 
Company Order with respect thereto, and in accordance with instructions given to
the Trustee and the U.S. Depository or such other depository, as the case may be
(which instructions shall be in writing but need not comply with Section 102 or
be accompanied by an Opinion of Counsel), as shall be specified in the Company
Order with respect thereto to the Trustee, as the Company's agent for such
purpose, to be exchanged, in whole or in part, for definitive Securities of the
same series without charge. The Trustee shall authenticate and make available
for delivery, in exchange for each portion of such surrendered global Security,
a like aggregate principal amount of definitive Securities of the same series of
authorized denominations and of like tenor as the portion of such global
Security to be exchanged which (unless the Securities of such series are not
issuable both as Bearer Securities and as Registered Securities, in which case
the definitive Securities exchanged for the global Security shall be issuable
only in the form in which the Securities are issuable, as specified as
contemplated by Section 301) shall be in the form of Bearer Securities or
Registered Securities, or any combination thereof, as shall be specified by the
beneficial owner thereof; provided, however, that no such exchanges may occur
during a period beginning at the opening of business 15 days before any
selection of Securities of such series to be redeemed and ending on the relevant
Redemption Date; and provided, further, that (unless otherwise specified as
contemplated by Section 301) no Bearer Security delivered in exchange for a
portion of a global Security shall be mailed or otherwise delivered to any
location in the United States. Promptly following any such exchange in part,
such global Security shall be returned by the Trustee to such Depository or the
U.S. Depository, as the case may be, or such other depository or U.S. Depository
referred to above in accordance with the instructions of the Company referred to
above. If a Registered Security is issued in exchange for any portion of a
global Security after the close of business at the office or agency where such
exchange occurs on (i) any Regular Record Date and before the opening of
business at such office or agency on the relevant Interest Payment Date, or (ii)
any Special Record Date and before the opening of business at such office or
agency on the related proposed date for payment of interest or Defaulted
Interest, as the case may be, interest will not be payable on such Interest
Payment Date or proposed date for payment, as the case may be, in respect of
such Registered Security, but will be payable on such Interest Payment Date or
proposed date for payment, as the case may be, only to the Person to whom
interest in respect of such portion of such global Security is payable in
accordance with the provisions of this Indenture.
 
     All Securities endorsed thereon issued upon any registration of transfer or
exchange of Securities shall be the valid obligations of the Company evidencing
the same debt, and entitling the Holders thereof to the same benefits under this
Indenture as the Securities surrendered upon such registration of transfer or
exchange.
 
     Every Registered Security presented or surrendered for registration of
transfer or for exchange, redemption, repayment or conversion shall (if so
required by the Company or the Security Registrar for such series of Security
presented) be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to the Company and such 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, exchange,
redemption, repayment or conversion 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, 1107 or 1602 not
involving any transfer.
 
     Except as otherwise specified as contemplated by Section 301, the Company
shall not be required (i) to issue, register the transfer of or exchange any
Securities of any series during a period beginning at the opening of business 15
days before the day of the selection for redemption of Securities of such series
under Section 1103 and ending at the close of business on the day of such
selection, or (ii) to register the transfer of or exchange any Registered
Security so selected for redemption in whole or in part, except in the case of
any Security to be redeemed in part, the portion thereof not to be redeemed, or
(iii) to exchange any Bearer Security so selected for redemption except, to the
extent provided with respect to such Security, that such a Bearer Security may
be exchanged for a Registered Security of that series, provided that such
Registered Security shall be immediately surrendered for redemption with written
instruction for payment consistent with the provisions of this Indenture, or
(iv) to issue, register the transfer of or exchange any Security which, in
accordance with its terms specified as contemplated by Section 301, has been
surrendered for repayment at the option of the Holder, except the portion, if
any, of such Security not to be repaid.

     Section 306.  Mutilated, Destroyed, Lost and Stolen Securities.
 
     If any mutilated Security or a Security with a mutilated Coupon
appertaining to it is surrendered to the Trustee, subject to the provisions of
this Section 306, the Company shall execute and the Trustee shall authenticate
and deliver in exchange therefor a new Security of the same series containing
identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons corresponding to the Coupons, if
any, appertaining to the surrendered Security.
 
     If there be delivered to the Company and to the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security or Coupon,
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice to
the Company or the Trustee that such Security or Coupon has been acquired by a
bona fide purchaser, the Company shall execute and upon its request the Trustee
shall authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Security or in exchange for the Security to
which a destroyed, lost or stolen Coupon appertains with all appurtenant Coupons
not destroyed, lost or stolen, a new Security of the same series containing
identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons corresponding to the Coupons, if
any, appertaining to such destroyed, lost or stolen Security or to the Security
to which such destroyed, lost or stolen Coupon appertains.
 
     Notwithstanding the foregoing provisions of this Section 306, in case any
such mutilated, destroyed, lost or stolen Security or Coupon has become or is
about to become due and payable, the Company in its discretion may, instead of
issuing a new Security, pay such Security or Coupon; provided, however, that
payment of principal of (and premium, if any) and any interest on Bearer
Securities shall, except as otherwise provided in Section 1002, be payable only
at an office or agency located outside the United States.
 
     Upon the issuance of any new Security under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.
 
     Every new Security of any series, with its Coupons, if any, issued pursuant
to this Section in lieu of any destroyed, lost or stolen Security and its
Coupons, if any, or the destroyed, lost or stolen Coupon shall constitute a
separate obligation of the Company, whether or not the destroyed, lost or stolen
Security and its Coupons, if any, or the destroyed, lost or stolen Coupon shall
be at any time enforceable by anyone, and shall be entitled to all the benefits
of this Indenture equally and proportionately with any and all other Securities
of that series and their Coupons, if any.
 
     The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities or Coupons.
 
     Section 307.  Payment of Interest; Interest Rights Preserved.
 
     Unless otherwise specified as contemplated by Section 301, interest on any
Registered Security which is payable, and is punctually paid or duly provided
for, on any Interest Payment Date shall be paid to the Person in whose name that
Security (or one or more Predecessor Securities) is registered as of the close
of business on the Regular Record Date for such interest. In case a Bearer
Security of any series is surrendered in exchange for a Registered Security of
such series after the close of business (at an office or agency in a Place of
Payment for such series) on any Regular Record Date and before the opening of
business (at such office or agency) on the next succeeding Interest Payment
Date, such Bearer Security shall be surrendered without the Coupon relating to
such Interest Payment Date and interest will not be payable on such Interest
Payment Date in respect of the Registered Security issued in exchange of such
Bearer Security, but will be payable only to the Holder of such Coupon when due
in accordance with the provisions of this Indenture.
 
     Any interest on any Registered Security of any series which shall be
payable, but shall not be punctually paid or duly provided for, on any Interest
Payment Date for such Registered Security (herein called "Defaulted Interest")
shall forthwith cease to be payable to the Holder on the relevant Regular Record
Date
 
                                       19
<PAGE>   27
 
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 Registered Securities affected (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 such Registered Security and the date of the proposed payment, and
     at the same time the Company shall deposit with the Trustee an amount of
     money equal to the aggregate amount proposed to be paid in respect of such
     Defaulted Interest or shall make arrangements satisfactory to the Trustee
     for such deposit prior to the date of the proposed payment, such money when
     deposited to be held in trust for the benefit of the Persons entitled to
     such Defaulted Interest as in this Clause provided. Thereupon, the Trustee
     shall fix a Special Record Date for the payment of such Defaulted Interest
     which shall be not more than 15 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 such Registered
     Securities at his address as it appears in the Security Register not less
     than 10 days prior to such Special Record Date. Notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor
     having been mailed as aforesaid, such Defaulted Interest shall be paid to
     the Persons in whose names such Registered Securities (or their respective
     Predecessor Securities) are registered at the close of business on such
     Special Record Date and shall no longer be payable pursuant to the
     following Clause (2). In case a Bearer Security of any series is
     surrendered at the office or agency in a Place of Payment for such series
     in exchange for a Registered Security of such series after the close of
     business at such office or agency on any Special Record Date and before the
     opening of business at such office or agency on the related proposed date
     for payment of Defaulted Interest, such Bearer Security shall be
     surrendered without the Coupon relating to such proposed date of payment
     and Defaulted Interest will not be payable on such proposed date of payment
     in respect of the Registered Security issued in exchange for such Bearer
     Security, but will be payable only to the Holder of such Coupon when due in
     accordance with the provisions of this Indenture.
 
          (2) The Company may make payment of any Defaulted Interest in any
     other lawful manner not inconsistent with the requirements of any
     securities exchange on which 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 payment shall be deemed practicable by the Trustee.
 
     At the option of the Company, interest on Registered Securities of any
series that bear interest may be paid by mailing a check to the address of the
person entitled thereto as such address shall appear in the Security Register.
 
     Subject to the foregoing provisions of this Section and Section 305, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.
 
     Section 308.  Persons Deemed Owners.
 
     Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered as the
owner of such Registered Security for the purpose of receiving payment of
principal of (and premium, if any), and (subject to Sections 305 and 307)
interest on or any Additional Amounts with respect to, such Registered Security,
for the purpose of conversion and for all other purposes whatsoever, whether or
not any payment with respect to such Registered Security be overdue, and neither
the Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.
 
                                       20
<PAGE>   28
 
     The Company, the Trustee and any agent of the Company or the Trustee may
treat the bearer of any Bearer Security and the bearer of any Coupon as the
absolute owner of such Security or Coupon for the purpose of receiving payment
thereof or on account thereof, for the purpose of conversion and for all other
purposes whatsoever, whether or not any payment with respect to such Security or
Coupon be overdue, and neither the Company, the Trustee nor any agent of the
Company or the Trustee shall be affected by notice to the contrary.
 
     Section 309.  Cancellation.
 
     All Securities and Coupons surrendered for payment, redemption,
registration of transfer, exchange or conversion or for credit against any
sinking fund payment shall, if surrendered to any Person other than the Trustee
or the Security Registrar, be delivered to the Trustee or the Security
Registrar, and any such Securities and Coupons and Securities and Coupons
surrendered directly to the Trustee or the Security Registrar for any such
purpose shall be promptly cancelled by the Trustee or the Security Registrar, as
the case may be. The Company may at any time deliver to the Trustee or the
Security Registrar for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Securities so delivered shall be promptly cancelled by the
Trustee or the Security Registrar, as the case may be. No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section, except as expressly permitted by this Indenture or as otherwise
specified as contemplated by Section 301. All cancelled Securities and Coupons
held by the Trustee or the Security Registrar shall be disposed of in accordance
with their customary procedures by the Trustee or the Security Registrar, as the
case may be, or retained in accordance with their regular practice, unless by a
Company Order the Company directs their return to it. The Trustee shall promptly
notify the Company of all Securities cancelled by it.
 
     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 401.  Satisfaction and Discharge of Indenture.
 
     Upon the direction of the Company by a Company Order, this Indenture shall
cease to be of further effect with respect to any series of Securities specified
in such Company Order (except as to any surviving rights of conversion,
registration of transfer or exchange of Securities of such series herein
expressly provided for and any right to receive Additional Amounts, as provided
in Section 1004), and the Trustee, on receipt of a Company Order, at the expense
of the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture as to such series, when
 
        (1) either
 
             (A) all Securities of such series theretofore authenticated and
        delivered and all Coupons appertaining thereto (other than (i) Coupons
        appertaining to Bearer Securities of such series surrendered for
        exchange for Registered Securities of such series and maturing after
        such exchange, whose surrender is not required or has been waived as
        provided in Section 305, (ii) Securities and Coupons of such series
        which have been destroyed, lost or stolen and which have been replaced
        or paid as provided in Section 306, (iii) Coupons appertaining to
        Securities of such series called for redemption and maturing after the
        relevant Redemption Date, whose surrender has been waived as provided in
        Section 1107, and (iv) Securities and Coupons of such series for whose
        payment money has theretofore been deposited in trust or segregated and
        held in trust by the Company and thereafter repaid to the Company or

        below, any such Coupons appertaining thereto not theretofore delivered
        to the Trustee for cancellation
 
                (i) have become due and payable, or
 
                (ii) will become due and payable at their Stated Maturity within
           one year, or

           to the Trustee for the giving of notice of redemption by the Trustee
           in the name, and at the expense, of the Company,
 
          and the Company, in the case of (i), (ii) or (iii) above, has
     deposited or caused to be deposited with the Trustee as trust funds in
     trust specifically pledged as security for, and dedicated solely to, the
     benefit of the Holders of the Securities of such series, (A) lawful money
     of the United States, or (B) Government Obligations which through the
     payment of interest and principal or other amounts in respect thereof in
     accordance with their terms, will provide not later than the opening of
     business on the due dates of any payment of principal (and premium, if any)
     and interest, or any Additional Amounts with respect thereto money in an
     amount or (C) a combination thereof, sufficient in the written opinion of
     Independent Public Accountants delivered to the Trustee to pay and
     discharge the entire indebtedness on such Securities and Coupons not
     theretofore delivered to the Trustee for cancellation, including principal
     (and premium, if any) and interest, or any Additional Amounts with respect
     thereto, to the date of such deposit (in the case of Securities which have
     become due and payable) or to the Stated Maturity or Redemption Date, as
     the case may be;
 
          (2) the Company has paid or caused to be paid all other sums payable
     hereunder by the Company with respect to such series of Securities; and
 
          (3) the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent
     herein provided for relating to the satisfaction and discharge of this
     Indenture as to such series have been complied with.
 
     In the event there are Securities of two or more series hereunder, the
Trustee shall be required to execute an instrument acknowledging satisfaction
and discharge of this Indenture only if requested to do so with respect to
Securities of all series as to which it is Trustee and if the other conditions
thereto are met. In the event there are two or more Trustees hereunder, then the
effectiveness of any such instrument shall be conditioned upon receipt of such
instruments from all Trustees hereunder.
 
     Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 606 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of
this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.
 
     Section 402.  Application of Trust Money.
 
     Subject to the provisions of the last paragraph of Section 1003, all money
and/or Government Obligations deposited with the Trustee pursuant to Section
401, and all money received by the Trustee in respect of any such Government
Obligations, shall be held in trust and applied by it, in accordance with the
provisions of the Securities, the Coupons and this Indenture, to the payment,
either directly or through any Paying Agent (including the Company acting as its
own Paying Agent) as the Trustee may determine, to the Persons entitled thereto,
of the principal (and premium, if any) and any interest or any Additional
Amounts for whose payment such money has and Government Obligations have been
deposited with the Trustee; but such money and Government Obligations need not
be segregated from other funds except to the extent required by law.
 
     All monies and/or Government Obligations deposited with the Trustee
pursuant to Section 401 (and held by it or any Paying Agent) for the payment of
Convertible Securities subsequently converted shall be returned to the Company
upon Company Request.

     Section 501.  Events of Default.
 
     "Event of Default", wherever used herein with respect to Securities of any
series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or be effected by operation
of law pursuant to any judgment, decree or order of any court or any order, rule
or regulation of any administrative or governmental body):
 
          (1) a court having jurisdiction in the premises shall enter a decree
     or order for relief in respect of the Company or a Principal Constituent
     Bank in an involuntary case under any applicable bankruptcy, insolvency or
     other similar law now or hereafter in effect, or adjudging it bankrupt or
     insolvent, or appointing a receiver, liquidator, assignee, custodian,
     trustee, sequestrator (or similar official) of the Company or a Principal
     Constituent Bank or for any substantial part of the Company's property, or
     ordering the winding-up or liquidation of its affairs, and such decree or
     order shall remain unstayed and in effect for a period of 60 consecutive
     days; or
 
          (2) the Company or a Principal Constituent Bank shall commence a
     voluntary case under any applicable bankruptcy, insolvency or other similar
     law now or hereafter in effect, or shall consent to the entry of an order
     for relief in any involuntary case under any such law, or shall consent to
     the appointment of or taking possession by a receiver, liquidator,
     assignee, trustee, custodian, sequestrator (or similar official) of the
     Company or a Principal Constituent Bank or for any substantial part of the
     Company's property, or shall make any general assignment for the benefit of
     creditors, or shall fail generally to pay its debts as they become due or
     shall take any corporate action in furtherance of any of the foregoing.
 
     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 and any
related Coupons 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 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 the Trustee or the Holders of not
less than 25% in principal amount of the Outstanding Securities of that series
may declare the principal of all the Securities of that series, or such lesser
amount as may be provided for in 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 the Holders), and upon any such declaration such principal or such
lesser amount shall become immediately due and payable.
 
     At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of not less than a majority in principal amount of
the Outstanding Securities of that series, by written notice to the Company and
the Trustee, may rescind and annul such declaration and its consequences if
 
          (1) the Company has paid or deposited with the Trustee a sum
     sufficient to pay
 
             (A) all overdue installments of interest on and any Additional
        Amounts payable in respect of all Outstanding Securities of such series,
 
             (B) the principal of (and premium, if any, on) any Securities of
        such series which have become due otherwise than by such declaration of
        acceleration and interest thereon at the rate or rates borne by or
        provided for in such Securities,
 
                                       23
<PAGE>   31
 
             (C) to the extent that payment of such interest is lawful, interest
        upon overdue installments of interest or any Additional Amounts at the
        rate or rates borne by or provided for 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 as provided in Section 606 hereof; and
 
          (2) all Defaults with respect to Securities of such series have been
     cured or waived as provided in Section 513.
 
No such rescission shall affect any subsequent default or impair any right
consequent thereon.
 
     Section 503.  Collection of Indebtedness and Suits for Enforcement by
Trustee.
 
     The Company covenants that if
 
          (1) default is made in the payment of any installment of interest on
     or any Additional Amounts payable in respect of any Security when such
     interest or Additional Amounts shall have become 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 its Maturity,
 
the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities and Coupons, the whole amount then due and payable on
such Securities and any Coupons appertaining thereto for principal (and premium,
if any) and interest or Additional Amounts, if any, with interest upon the
overdue principal (and premium, if any) and, to the extent that payment of such
interest shall be legally enforceable, upon overdue installments of interest or
any Additional Amounts, at the rate or rates borne by or provided for 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, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon such Securities and collect the
monies adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Securities and
Coupons (if any), wherever situated.
 
     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 and any
Coupons appertaining thereto 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 such Securities or in aid of the exercise of any power granted
herein, or to enforce any other proper remedy.
 
     Section 504.  Trustee May File Proofs of Claim.
 
     In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of any overdue principal or interest) shall be
entitled and empowered, by intervention in such proceeding or otherwise,
 
          (i) to file and prove a claim for the whole amount or such lesser
     amount as may be provided for in the Securities of such series, of
     principal (and premium, if any) and interest and any Additional Amounts
 
                                       24
<PAGE>   32
 
     owing and unpaid in respect of the Securities and any Coupons appertaining
     thereto and to file such other papers or documents as may be necessary or
     advisable in order to have the claims of the Trustee (including any claim
     for the reasonable compensation, expenses, disbursements and advances of
     the Trustee, its agents or counsel) and of the Holders allowed in such
     judicial proceeding, and
 
          (ii) to collect and receive any monies 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 of Securities or Coupons to make such payments to the Trustee or, in
the event that the Trustee shall consent to the making of such payments directly
to the Holders of Securities or Coupons, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel and any other amounts due the Trustee under
Section 606.
 
     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Security
or Coupon any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or Coupons or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder of a
Security or Coupon in any such proceeding.
 
     Section 505.  Trustee May Enforce Claims without Possession of Securities
or Coupons.
 
     All rights of action and claims under this Indenture or any of the
Securities or Coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or Coupons or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery or judgment, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, shall be for the ratable benefit of the Holders of the Security or
Coupon 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 (and premium,
if any), interest or any Additional Amounts, upon presentation of the Securities
or Coupons, or both, as the case may be, and the notation thereon of the payment
if only partially paid and upon surrender thereof if fully paid:

              any), interest or any Additional Amounts, respectively;

     Section 507.  Limitation on Suits.
 
     No Holder of any Security of any series or any related Coupons shall have
any right to institute any proceeding, judicial or otherwise, with respect to
this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless
 
          (1) such Holder has previously given written notice to the Trustee of
     a continuing Default with respect to the Securities of such series;
 
                                       25
<PAGE>   33
 
          (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
 
          (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 such 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 or any Security to affect, disturb or prejudice the rights of
any other such Holders or Holders of Securities of any other series, or to
obtain or to seek to obtain priority or preference over any other Holders or to
enforce any right under this Indenture, except in the manner herein provided and
for the equal and ratable benefit of all such Holders.
 
     Section 508.  Unconditional Right of Holders to Receive Principal, Premium,
Interest and Additional Amounts and to Convert any Convertible Security.
 
     Notwithstanding any other provision in this Indenture, the Holder of any
Security or Coupon shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Sections 305 and 307) interest on or any Additional Amounts in respect of such
Security or payment of such Coupon on the respective Stated Maturity or
Maturities specified in such Security or Coupon (or, in the case of redemption,
on the Redemption Date or, in the case of repayment, on the date such repayment
is due) and to institute suit for the enforcement of any such payment, and shall
have the right to convert any such Security which is a Convertible Security in
accordance with the terms hereof and thereof and to institute suit for
enforcement of such right; and such rights shall not be impaired without the
consent of such Holder.
 
     Section 509.  Restoration of Rights and Remedies.
 
     If the Trustee or any Holder of a Security or Coupon has instituted any
proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Trustee or to such Holder, then and in every such
case the Company, the Trustee and each such Holder shall, subject to any
determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Trustee and each such Holder shall continue as though no such proceeding had
been instituted.
 
     Section 510.  Rights and Remedies Cumulative.
 
     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities or Coupons in the last paragraph
of Section 306, no right or remedy herein conferred upon or reserved to the
Trustee or to each and every Holder of a Security or Coupon is intended to be
exclusive of any other right or remedy, and every right and remedy, to the
extent permitted by law, shall be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in
equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.
 
     Section 511.  Delay or Omission Not Waiver.
 
     No delay or omission of the Trustee or of any Holder of any Security or
coupon to exercise any right or remedy accruing upon any 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 any Holders of a Security or a Coupon may be exercised from
time to time, and as often as may be deemed expedient, by the Trustee or by such
Holder, 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 and any Coupons appertaining thereto, provided that
 
          (1) such direction shall not be in conflict with any rule of law or
     with this Indenture,
 
          (2) the Trustee may take any other action deemed proper by the Trustee
     which is not inconsistent with such direction, and
 
          (3) such direction is not unduly prejudicial to the rights of other
     Holders of Securities of such series and could not involve the Trustee in
     personal liability.
 
     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 and any Coupons appertaining thereto waive any past
default hereunder with respect to such series and its consequences, except a
default
 
          (1) in the payment of the principal of (and premium, if any) or
     interest on or Additional Amounts payable in respect of any Security of
     such series or any Coupons appertaining thereto, or
 
          (2) in respect of a covenant or provision hereof which under Article
     Nine cannot be modified or amended without the consent of the Holder of
     each Outstanding Security of such series affected.
 
     Upon any such waiver, such default shall cease to exist, and any Default
arising therefrom shall be deemed to have been cured, for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other default or
impair any right consequent thereon.
 
     "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 Fifteen 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 of any
administrative or governmental body):
 
          (1) an Event of Default with respect to that series specified in
     section 501; or
 
          (2) any event referred to in clause (1) or (2) of the first paragraph
     of this Section 503 with respect to Securities of that series; or
 
          (3) 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 the performance of which or the breach of which 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
 
          (4) any other Default provided with respect to Securities of that
     series.
 
     Section 514.  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.

cured or waived; provided, however, that, except in the case of a default in the
payment of the principal of (or premium, if any) or interest on, or any
Additional Amounts with respect to, any Security of such series or in the
payment of any sinking fund installment with respect to Securities of such
series, the Trustee shall be protected in withholding such notice if and so long
as the board of directors, the executive committee or a trust committee of
directors and/or Responsible Officers of the Trustee in good faith determine
that the withholding of such notice is in the interests of the Holders of
Securities and Coupons of such series.

     refraining from acting upon any resolution, certificate, statement,

     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture or other paper or document, but the Trustee, in its
     discretion, may make such further inquiry or investigation into such facts
     or matters as it may see fit, and, if the Trustee shall determine to make
     such further inquiry or investigation, it shall be entitled to examine the
     books, records and premises of the Company, personally or by agent or
     attorney; and
 
          (g) the Trustee may execute any of the trusts or powers hereunder or
     perform any duties hereunder either directly or by or through agents or
     attorneys and the Trustee shall not be responsible for any misconduct or
     negligence on the part of any agent or attorney appointed with due care by
     it hereunder.
 
          (h) The Trustee shall not be charged with knowledge of any Default
     (other than a default in any payment with respect to a Security due on a
     fixed date and with respect to which the Trustee is a Paying Agent) unless
     either (1) a Responsible Officer of the Trustee shall have actual knowledge
     of the Default

     Section 603.  Not Responsible for Recitals or Issuance of Securities.
 
     The recitals contained herein and in the Securities, except the Trustee's
certificate of authentication, and in any Coupons shall be taken as the
statements of the Company and the Trustee or any Authenticating Agent assumes no
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture or of the Securities or Coupons,
except that the Trustee represents that it is duly authorized to execute and
deliver this Indenture, authenticate the Securities and perform its obligations
hereunder and that the statements made by it in a Statement of Eligibility on
Form T-1 supplied to the Company are true and accurate, subject to the
qualifications set forth therein. The Trustee or any Authenticating Agent shall

          (1) to pay to the Trustee from time to time such compensation for all

     Trustee upon its request for all reasonable expenses, disbursements and

     expense, disbursement or advance as may be attributable to its negligence
     or bad faith; and
 
          (3) to indemnify the Trustee and its agents for, and to hold them
     harmless against, any loss, liability or expense incurred without
     negligence or bad faith on their part, arising out of or in connection with
     the acceptance or administration of the trust or trusts hereunder,
     including the costs and expenses of defending themselves against any claim
     or liability in connection with the exercise or performance of any of their
     powers or duties hereunder.
 
     As security for the performance of the obligations of the Company under
this Section, the Trustee shall have a lien prior to the Securities of any
series upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the payment of principal of (or premium, if any)
or interest on particular Securities. Without limiting any other rights
available to the Trustee under applicable law, when the Trustee incurs expenses
or renders services after an Event of Default occurs, the expenses and
compensation for the services of the Trustee are intended to constitute expenses
of administration under any bankruptcy law or any similar federal or state law
for the relief of debtors.

surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture
Act) of at least $50,000,000. If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article. If the Trustee has or shall acquire any conflicting interest, as
defined in Section 310(b) of the Trust Indenture Act, with respect to the
Securities of any series, the Trustee shall take such action as is required
pursuant to said Section 310(b), subject to the penultimate paragraph thereof.
 
     Section 608.  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 pursuant to Section 609.
 
     (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 609 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 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 the Company.
 
     (d) If at any time:
 
          (1) the Trustee shall fail to comply with the obligations imposed upon
     it under Section 310(b) of the Trust Indenture Act after written request
     therefor by the Company or by any Holder of a Security 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 607 and shall
     fail to resign after written request therefor by the Company or by any such
     Holder of a Security, or
 
          (3) the Trustee shall become incapable of acting or shall be adjudged
     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 or pursuant to a Board Resolution,
may remove the Trustee with respect to all Securities, or (ii) subject to
Section 315(e) of the Trust Indenture Act, any Holder of a Security who has been
a bona fide Holder of a Security of any series for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee with respect to all
Securities of such series 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 or pursuant to 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 609. 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

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 of Securities and accepted appointment
in the manner required by Section 609, any Holder of a Security 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 appointment of
a successor Trustee with respect to the Securities of any series by mailing
written notice of such event by first-class mail, postage prepaid, to the
Holders of Registered Securities, if any, of such series as their names and
addresses appear in the Security Register and, if Securities of such series are
issued as Bearer Securities, by publishing notice of such event once in an
Authorized Newspaper in each Place of Payment located outside the United States.

execute, acknowledge and deliver to the Company and 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 and/or the successor Trustee, such retiring Trustee shall, upon
payment of its charges, execute and deliver an instrument transferring to such
successor Trustee all the rights, powers and trusts of the retiring Trustee and
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder, subject nevertheless to its
lien, if any, provided for in Section 606.
 
     (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, 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 that no Trustee shall be responsible for any notice
given to, or received by, or any act or failure to act on the part of any other
Trustee hereunder, 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, such retiring Trustee shall with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates have no further responsibility for the exercise
of rights and powers or for the performance of the duties and obligations vested
in the Trustee under this Indenture other than as hereinafter expressly set
forth, 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, to the extent contemplated by
such supplemental indenture, the 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.

<PAGE>   39
 
     (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 610.  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 of 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 611.  Appointment of Authenticating Agent.
 
     The Trustee may appoint an Authenticating Agent or Authenticating Agents,
which may be an Affiliate of the Company, with respect to one or more series of
Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of that or those series issued upon original issue or
exchange, registration of transfer or partial redemption or conversion 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, except as
specified as contemplated by Section 301, shall at all times be a corporation
that would be permitted by Section 310(a)(1) and (5) of the Trust Indenture Act
to be able to act as a trustee under an indenture qualified under the Trust
Indenture Act, is authorized under applicable law and by its charter to act as
such and that has a combined capital and surplus (computed in accordance with
Section 310(a)(2) of the Trust Indenture Act) of not less that $50,000,000. 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. If the
Authenticating Agent has or shall acquire any conflicting interest, as defined
in Section 310(b) of the Trust Indenture Act, with respect to the Securities of
any series, the Authenticating Agent shall take such action as is required
pursuant to said Section 310(b).
 
     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 all or substantially all of
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 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 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 (i) mail written notice
of such appointment by first-class mail, postage prepaid, to all Holders of
Registered Securities, if any, of the series with respect to which such
Authenticating Agent will serve, as their names and addresses appear in the
Security Register, and (ii) if
 
                                       32
<PAGE>   40
 
Securities of the series are issued as Bearer Securities, publish notice of such
appointment at least once in an Authorized Newspaper in the place where such
successor Authenticating Agent has its principal office if such office is
located outside the United States. 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 each Authenticating Agent from time to time
reasonable compensation for its services under this Section. If the Trustee
makes such payments, it shall be entitled to be reimbursed for such payments,
subject to the provisions of Section 606.
 
     The provisions of Sections 308, 603 and 604 shall be applicable to each
Authenticating Agent.
 
     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 or in lieu of the Trustee's certificate of authentication, an
alternate certificate of authentication in the following form:
 
     This is one of the Securities of the series designated herein referred to
in the within-mentioned Indenture.

If all of the Securities of any series may not be originally issued at one time,
and if the Trustee does not have an office capable of authenticating Securities
upon original issuance located in a Place of Payment where the Company wishes to
have Securities of such series authenticated upon original issuance, the
Trustee, if so requested in writing (which writing need not comply with Section
102) by the Company, shall appoint in accordance with this Section, and in
accordance with such procedures as shall be acceptable to the Trustee, an
Authenticating Agent having an office in a Place of Payment designated by the
Company with respect to such series of Securities.

     Coupons appertaining thereto as permitted by Sections 201 and 301; or
 
          (5) to evidence and provide for the acceptance of appointment
     hereunder by a successor Trustee with respect to the Securities of one or
     more series and to 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, pursuant to the requirements
     of Section 609(b); or
 
          (6) to cure any ambiguity, to correct or supplement any provision
     herein which may be defective or inconsistent with any other provision
     herein, or to make any other provisions with respect to matters or
     questions arising under this Indenture which shall not be inconsistent with
     the provisions of this Indenture and which shall not adversely affect the
     interest of the Holders of Securities of any series or any related Coupons
     in any material respect; or
 
          (7) to add to, delete from or revise the conditions, limitations and
     restrictions on the authorized amount, terms or purposes of issue,

          (9) to modify, eliminate or add to the provisions of this Indenture to
     such extent as shall be necessary to conform the obligations of the Company
     and the Trustee under this Indenture to the obligations imposed on such
     Person hereunder pursuant to the Trust Indenture Act or under any similar
     federal statute hereafter enacted, and any rules or regulations of the
     Commission thereunder; or
 
          (10) to make provision with respect to the conversion rights of
     Holders of Convertible Securities pursuant to the requirements of Section
     1606.
 
          (11) to modify, delete or add to any of the provisions of this
     Indenture other than as contemplated by classes (1) through (10) of this
     Section; provided that any such modification, deletion or addition shall
     become effective only with respect to series of Securities established
     pursuant to Section 301 after the effective date of such modification,
     deletion, or addition.
 
          (12) to modify, delete or add to any of the provisions of this

     Section 902.  Supplemental Indentures with Consent of Holders.
 
     With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company, when authorized by Board Resolutions, 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

that no such supplemental Indenture, without the consent of the Holder of each
Outstanding Security affected thereby, shall
 
          (1) change the Stated Maturity of the principal of, or any installment
     of interest on, any Security, or reduce the principal amount thereof or the
     rate of interest thereon or any Additional Amounts payable in respect
     thereof, or any premium payable upon the redemption thereof, or change the

     Securities of any series, the consent of whose Holders is required for any
     such supplemental indenture, or the consent of whose Holders is required

     subordination of the Securities in a manner adverse to the Holders; or
 
          (5) adversely affect the right to convert any Convertible Security.

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

protected in relying upon, an Opinion of Counsel stating that the execution of

     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 a Security theretofore or thereafter authenticated and delivered hereunder
and of any Coupons appertaining thereto shall be bound thereby.

     Section 906.  Reference in Securities to Supplemental Indentures.
 
     Securities of any series authenticated and delivered after the execution of
any supplemental indenture pursuant to this Article may, and shall if required
by the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company shall so determine,
new Securities of any series so modified as to conform, in the opinion of the
Trustee and the Company, to any such supplemental indenture may be prepared and
executed by the Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities of such series.
 
     Section 907.  Subordination Unimpaired.
 
     No supplemental indenture entered into under this Article shall modify,
directly or indirectly, the provisions of Article Fifteen or the definition of

subordination of the Securities with respect to Senior Indebtedness then
outstanding, unless each holder of such Senior Indebtedness has consented
thereto in writing.

                                   COVENANTS
 
     Section 1001.  Payment of Principal, Premium, if any, and Interest.
 
     The Company covenants and agrees for the benefit of the Holders of each
series of Securities that it will duly and punctually pay the principal of (and
premium, if any), interest on or any Additional Amounts payable in respect of
the Securities of that series in accordance with the terms of such series of
Securities, any Coupons appertaining thereto and this Indenture. Any interest
due on and any Additional Amounts payable in respect of Bearer Securities on or
before Maturity, other than Additional Amounts, if any, payable as provided in
Section 1004 in respect of principal of (or premium, if any, on) such a
Security, shall be payable only upon presentation and surrender of the several
coupons for such interest installments as are evidenced thereby as they
severally mature.
 
     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 such series (but not Bearer
Securities, except as otherwise provided below, unless such Place of Payment is
located outside the United States) may be presented or surrendered for payment,
where Securities of that series may be surrendered for registration of transfer,
exchange or, if applicable, conversion and where notices and demands to or upon
the Company in respect of the Securities of that series and this Indenture may
be served. If Securities of a series are issuable as Bearer Securities, the
Company shall maintain, subject to any laws or regulations applicable thereto,
an office or agency in a Place of Payment for such series which is located
outside the United States where Securities of such series and the related
Coupons may be presented and surrendered for payment (including payment of any
Additional Amounts payable on Securities of such series pursuant to Section
1004); provided, however, that if the Securities of such series are listed on
The Stock Exchange of the United Kingdom and the Republic of Ireland or the
Luxembourg Stock Exchange or any other stock exchange located outside the United
States and such stock exchange shall so require, the Company shall maintain a
Paying Agent in London, Luxembourg or any other required city
 
                                       38
<PAGE>   46
 
located outside the United States, as the case may be, so long as the Securities
of such series are listed on such exchange. The Company will give prompt written
notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Company shall fail to maintain any such
required office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, except that Bearer
Securities of that series and the related Coupons may be presented and
surrendered for payment (including payment of any Additional Amounts payable on
Bearer Securities of that series pursuant to Section 1004) at the place
specified for the purpose pursuant to Section 301, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands.
 
     Except as otherwise specified as contemplated by Section 301, no payment of
principal, premium or interest on Bearer Securities shall be made at any office
or agency of the Company in the United States or by check mailed to any address
in the United States or by transfer to an account maintained with a bank located
in the United States; provided, however, payment of principal of and any premium
and interest in U.S. dollars (including Additional Amounts payable in respect
thereof) on any Bearer Security may be made at the Corporate Trust Office or any
office or agency designated by the Company in the Borough of Manhattan, The City
of New York if (but only if) payment of the full amount of such principal,
premium, interest or Additional Amounts at all offices outside the United States
maintained for the purpose by the Company in accordance with this Indenture is
illegal or effectively precluded by exchange controls or other similar
restrictions.
 
     The Company may also from time to time designate one or more other offices
or agencies where the Securities of one or more series may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency
in each Place of Payment for Securities of any series for such purposes. The
Company will give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency. Unless otherwise specified as contemplated by Section 301, the Company
hereby designates as the Place of Payment and as Paying Agent for each series
the Corporate Trust Office. The Company may subsequently appoint another place
or places in the Borough of Manhattan, The City of New York where such
Securities may be payable.
 
     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 premium, if any), or interest on, any of the Securities of
that series, segregate and hold in trust for the benefit of the Person entitled
thereto a sum sufficient to pay the principal (and premium, if any) 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, on or prior to each due date of the principal of (and
premium, if any), or interest on, any Securities of that series, deposit with
any Paying Agent a sum sufficient to pay the principal (and premium, if any) or
interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal, premium or interest, and (unless such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its action
or failure so to act.
 
     The Company will cause each Paying Agent for any series of Securities other
than the Trustee to execute and deliver to the Trustee an instrument in which
such Paying Agent shall agree with the Trustee, subject to the provisions of
this Section, that such Paying Agent will:
 
          (1) hold all sums held by it for the payment of the principal of (and
     premium, if any) or interest on Securities of that series in trust for the
     benefit of the Persons entitled thereto until such sums shall be paid to
     such Persons or otherwise disposed of as herein provided;
 
                                       39
<PAGE>   47
 
          (2) give the Trustee notice of any default by the Company (or any
     other obligor upon the Securities of that series) in the making of any
     payment of principal (and premium, if any) or interest on the Securities of
     that series; and
 
          (3) at any time during the continuance of any such default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent.
 
     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same terms 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.
 
     Except as otherwise provided hereby or pursuant hereto, 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 premium, if any) or interest and Additional
Amounts on any Security of any series and remaining unclaimed for two years
after such principal (and premium, if any) or interest has become due and
payable shall be paid to the Company on Company Request, or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Security or
any Coupon appertaining thereto shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease; provided, however,
that the Trustee or such Paying Agent, before being required to make any such
repayment, may at the expense of the Company cause to be published once, in an
Authorized Newspaper in each Place of Payment for such series or to be mailed to
Holders of Registered Securities for such series, or both, 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 or mailing any
unclaimed balance of such money then remaining will be repaid to the Company.
 
     Section 1004.  Additional Amounts.
 
     If any Securities of a series provide for the payment of Additional
Amounts, the Company agrees to pay to the Holder of any such Security of any
such series or any Coupon appertaining thereto Additional Amounts as provided
therein. Whenever in this Indenture there is mentioned, in any context, the
payment of the principal of (or premium, if any) or interest on, or in respect
of, any Security of any series or any Coupon or the net proceeds received on the
sale or exchange of any Security of any series, such mention shall be deemed to
include mention of the payment of Additional Amounts provided by the terms of
such series established hereby or pursuant hereto to the extent that, in such
context, Additional Amounts are, were or would be payable in respect thereof
pursuant to such terms and express mention of the payment of Additional Amounts
(if applicable) in any provisions hereof shall not be construed as excluding
Additional Amounts in those provisions hereof where such express mention is not
made.
 
     Except as otherwise provided herein or pursuant hereto, if the Securities
of a series provide for the payment of Additional Amounts, at least 10 days
prior to the first Interest Payment Date with respect to such series of
Securities (or if the Securities of that series shall not bear interest prior to
Maturity, the first day on which a payment of principal (and premium, if any) is
made), and at least 10 days prior to each date of payment or principal (and
premium, if any) or interest if there has been any change with respect to the
matters set forth in the below-mentioned Officers' Certificate, the Company will
furnish the Trustee and the principal Paying Agent or Paying Agents, if other
than the Trustee, an Officers' Certificate instructing the Trustee and such
Paying Agent or Paying Agents whether such payment of principal (and premium, if
any) of or interest on the Securities of that series shall be made to Holders of
Securities of that series or the Coupons appertaining thereto who are United
States Aliens without withholding for or on account of any tax, assessment or
other governmental charge described in the Securities of that series. If any
such withholding shall be required, then such Officers' Certificate shall
specify by country the amount, if any, required to be withheld on such payments
to such Holders of Securities or Coupons and the Company agrees to pay to the
Trustee or such Paying Agent the Additional Amounts required by this Section.
The Company covenants to
 
                                       40
<PAGE>   48
 
indemnify the Trustee and any Paying Agent for, and to hold them harmless
against, any loss, liability or expense reasonably incurred without negligence
or bad faith on their part arising out of or in connection with actions taken or
omitted by any of them in reliance on any Officers' Certificate furnished
pursuant to this Section.
 
     Section 1005.  Statement as to Compliance; Notice of Certain Defaults.
 
     (a) The Company will, in addition to the reports required by Section
704(4), deliver to the Trustee, within 120 days after the end of each fiscal
year (which on the date hereof ends on December 31), a written statement, which
need not comply with Section 102, signed by the Chairman of the Board, a Deputy
Chairman, a Vice Chairman, the President or a Vice President and by the
Treasurer or an Assistant Treasurer of the Company, stating, as to each signer
thereof, that
 
          (1) a review of the activities of the Company during such year and of
     performance under this Indenture has been made under his supervision, and
 
          (2) to the best of his knowledge, based on such review, (a) the
     Company has fulfilled all of its obligation under this Indenture throughout
     such year, or, if there has been a default in the fulfillment of any such
     obligation, specifying each such default known to him and the nature and
     status thereof, and (b) no event has occurred and is continuing which is,
     or after notice or lapse of time or both would become, a Default, or, if
     such an event has occurred and is continuing, specifying each such event
     known to him and the nature and status thereof.
 
          (b) The Company will deliver to the Trustee, within five days after
     the occurrence thereof, written notice of any event which after notice or
     lapse of time or both would become a Default.
 
     Section 1006.  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 1007.  Corporate Existence.
 
     Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence, rights (charter and statutory) and franchises and the corporate
existence, rights (charter and statutory) and franchises of each Principal
Constituent Bank; provided, however, that the Company shall not be required to
preserve any such corporate existence, right or franchise if the Company shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Company and its Subsidiaries considered as a whole and that
the loss thereof is not disadvantageous in any material respect to the Holders.
 
     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 Section 1006 with respect to the Securities
of any series if before the time for such compliance the Holders of at least a
majority in principal amount of the Outstanding Securities of such series shall,
by Act of such Holders, either waive such compliance in such instance or
generally waive compliance with such term, provision or condition, but no such
waiver shall extend to or affect such term, provision or condition except to the
extent so expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the duties of the Trustee in respect of any such
term, provision or condition shall remain in full force and effect.

                            REDEMPTION OF SECURITIES
 
     Section 1101.  Applicability of Article.
 
     Redemption of Securities of any series at the option of the Company as
permitted or required by the terms of such Securities shall be made in
accordance with the terms of such Securities and (except as otherwise provided
herein or pursuant hereto) this Article.
 
     Section 1102.  Election to Redeem; Notice to Trustee.
 
     The election of the Company to redeem any Securities shall be evidenced by
Board Resolution. In case of any redemption at the election of the Company of
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 and of
the principal amount of Securities of such series to be redeemed. In the case of
any redemption of Securities (a) prior to the expiration of any restriction on
such redemption provided in the terms of such Securities or elsewhere in this
Indenture or (b) pursuant to an election of the Company which is subject to a
condition specified 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 or condition.
 
     Section 1103.  Selection by Trustee of Securities to be Redeemed.
 
     If less than all the Securities of any series with the same issue date,
interest rate, Stated Maturity and other terms are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions of the principal amount of Registered Securities of such
series; provided, however, that no such partial redemption shall reduce the
portion of the principal amount of a Registered Security of such series not
redeemed to less than the minimum denomination for a Registered Security of such
series established herein pursuant hereto.
 
     If any Convertible Security selected for partial redemption is converted in
part before termination of the conversion right with respect to the portion of
the Security so selected, the converted portion of such Security shall be deemed
(so far as may be) to be the portion selected for redemption. Securities which
have been converted during a selection of Securities to be redeemed shall be
treated by the Trustee as Outstanding for the purpose of such selection.
 
     The Trustee shall promptly notify the Company and the Security Registrar
(if other than itself) 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 of such Securities which has been or is to be redeemed.
 
     Section 1104.  Notice of Redemption.
 
     Notice of redemption shall be given in the manner provided in Section 106,
not less than 30 nor more than 60 days prior to the Redemption Date, unless a
shorter period is specified in the Securities to be redeemed, to the Holders of
Securities to be redeemed. Failure to give notice by mailing in the manner
herein provided to the Holder of any Registered Securities designated for
redemption as a whole or in part, or any defect in the notice to any such
Holder, shall not affect the validity of the proceedings for the redemption of
any other Securities or portion thereof.
 
     Any notice that is mailed to the Holder of any Registered Securities in the
manner herein provided shall be conclusively presumed to have been duly given,
whether or not such Holder receives the notice.
 
                                       42
<PAGE>   50
 
     All notices of redemption shall state:
 
          (1) the Redemption Date,
 
          (2) the Redemption Price,
 
          (3) if less than all Outstanding Securities of any series are to be
     redeemed, the identification (and, in the case of partial redemption, the
     principal amount) of the particular Securities to be redeemed,
 
          (4) in case any Registered Security is to be redeemed in part only,
     that on and after the Redemption Date, upon surrender of such Security, the
     Holder of such Security will receive, without charge, a new Registered
     Security or Registered Securities of authorized denominations for the
     principal amount thereof remaining unredeemed,
 
          (5) that on the Redemption Date the Redemption Price will become due
     and payable upon each such Security to be redeemed only, against tender of
     such Security and any Coupons appertaining thereto, and, if applicable,
     that interest and Additional Amounts, if any, thereon shall cease to accrue
     on and after said date,
 
          (6) in the case of Convertible Securities, the Conversion Price then
     in effect, the date on which the right to convert the principal amount of
     the Securities or the portions thereof to be redeemed will terminate and
     the place or places where such Securities may be surrendered for
     conversion,
 
          (7) the place or places where such Securities, together, in the case
     of Bearer Securities with all Coupons appertaining thereto, if any,
     maturing after the Redemption Date, are to be surrendered for payment of
     the Redemption Price, and
 
          (8) that the redemption is for a sinking fund, if such is the case.
 
     A notice of redemption published as contemplated by Section 106 need not
identify particular Registered Securities to be redeemed.
 
     Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.
 
     Section 1105.  Deposit of Redemption Price.
 
     On or prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on and any Additional
Amounts with respect thereto, all the Securities or portions thereof which are
to be redeemed on that date.
 
     If any Convertible Security or portion thereof called for redemption is
converted pursuant to Article Sixteen, any money deposited with the Trustee or
so segregated and held in trust for the redemption of such Security or portion
thereof shall (subject to any right of the Holder of the Security on a Regular
Record Date preceding such conversion to receive interest) be paid to the
Company upon Company Request or, if then held by the Company, shall be
discharged from such trust.
 
     Section 1106.  Securities Payable on Redemption Date.
 
     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest and the Coupons for such
interest appertaining to any Bearer Securities so to be redeemed, except to the
extent provided below, shall be void. Upon surrender of any such Security for
redemption in accordance with said notice, together with all Coupons, if any,
appertaining thereto maturing after the Redemption Date, such Security shall be
paid by the Company at the Redemption Price, together with accrued interest (or
any Additional Amounts) to the Redemption Date; provided, however, that
installments of interest on Bearer Securities whose Stated Maturity is on or
prior to the Redemption Date
 
                                       43
<PAGE>   51
 
shall be payable only upon presentation and surrender of Coupons for such
interest (at an office or agency located outside the United States except as
otherwise provided in Section 1002), and provided, further, that installments of
interest on Registered Securities whose Stated Maturity is on or prior to the
Redemption Date shall be payable to the Holders of such Securities, or one or
more Predecessor Securities, registered as such at the close of business on the
Regular Record Dates according to their terms and the provisions of Section 307.
 
     If any Bearer Security surrendered for redemption shall not be accompanied
by all appurtenant Coupons maturing after the Redemption Date, such Security may
be paid after deducting from the Redemption Price an amount equal to the face
amount of all such missing Coupons, or the surrender of such missing Coupon or
Coupons may be waived by the Company and the Trustee if there be furnished to
them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender
to the Trustee or any Paying Agent any such missing Coupon in respect of which a
deduction shall have been made from the Redemption Price, such Holder shall be
entitled to receive the amount so deducted; provided, however, that interest (or
any Additional Amounts) represented by Coupons shall be payable only upon
presentation and surrender of those Coupons at an office or agency located
outside of the United States except as otherwise provided in Section 1002.
 
     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal (and premium, if any) shall, until paid,
bear interest from the Redemption Date at the rate prescribed therefor in the
Security.
 
     Section 1107.  Securities Redeemed in Part.
 
     Any Registered Security which is to be redeemed only in part shall be
surrendered at any office or agency of the Company maintained for that purpose
pursuant to Section 1002 (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing) and the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of such Security without service charge,
a new Registered Security or Securities of the same series, containing identical
terms and provisions, 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. If a Security in global
form is so surrendered, the Company shall execute, and the Trustee shall
authenticate and deliver to the U.S. Depository or other depository for such
Security in global form as shall be specified in the Company Order with respect
thereto to the Trustee, without service charge, a new Security in global form in
a denomination equal to and in exchange for the unredeemed portion of the
principal of the Security in global form so surrendered.
 
     Section 1108.  Conversion Arrangements on Call for Redemption.
 
     Notwithstanding anything to the contrary contained in this Indenture, in
connection with any redemption of Convertible Securities of any series, the
Company, by an agreement with one or more investment bankers or other
purchasers, may arrange for such purchasers to purchase all such Convertible
Securities called for redemption (the "Called Securities") which are either (i)
surrendered for redemption or (ii) not duly surrendered for redemption or
conversion prior to the close of business on the Redemption Date, and to convert
the same into shares of Common Stock, by the purchasers' depositing with the
Trustee (acting as Paying Agent with respect to the deposit of such amount and
as conversion agent with respect to the conversion of such Called Securities),
in trust for the Holders of the Called Securities, on or prior to the Redemption
Date in the manner agreed to by the Company and such purchasers, an amount
sufficient to pay the Redemption Price, payable by the Company on redemption of
such Called Securities. In connection with any such arrangement for purchase and
conversion, the Trustee as Paying Agent shall pay on or after the Redemption
Date such amounts so deposited by the purchasers in exchange for Called
Securities surrendered for redemption prior to the close of business on the
Redemption Date and for all Called Securities surrendered after such Redemption
Date. Notwithstanding anything to the contrary contained in this Article Eleven,
the obligation of the Company to pay the Redemption Price of such Called
Securities shall be satisfied and discharged to the extent such amount is so
paid by such purchasers, provided, however, that nothing in this Section 1108
shall in any way relieve the Company of the obligation to pay such Redemption
Price on all
 
                                       44
<PAGE>   52
 
Called Securities to the extent such amount is not so paid by said purchasers.
For all purposes of this Indenture, any Called Securities surrendered by the
Holders for redemption, and any Called Securities not duly surrendered for
redemption or conversion prior to the close of business on the Redemption Date,
shall be deemed acquired by such purchasers from such Holders and surrendered by
such purchasers for conversion and shall in all respects be deemed to have been
converted, all as of immediately prior to the close of business on the
Redemption Date, subject to the deposit by the Purchasers of the above amount as
aforesaid. Nothing in this Section 1108 shall in any way limit the right of any
Holder of a Security to convert his Security pursuant to the terms of this
Indenture and of such Security at any time prior to the close of business on the
Redemption Date applicable thereto. The Trustee shall hold and dispose of any
amount paid to it under this Section in the same manner as it would monies
deposited with it by the Company for the redemption of Securities. Without the
Trustee's prior written consent, no arrangement between the Company and such
purchasers for the purchase and conversion of any Securities shall increase or
otherwise affect any of the powers, duties, responsibilities or obligations of
the Trustee as set forth in this Indenture, and the Company agrees to indemnify
the Trustee from, and hold it harmless against, any loss, liability or expense
arising out of or in connection with any such arrangement for the purchase and
conversion of any Securities between the Company and such purchasers to which
the Trustee has not consented in writing, including the costs and expenses
incurred by the Trustee in the defense of any claim or liability arising out of
or in connection with the exercise or performance of any of its powers, duties,
responsibilities or obligations under this Indenture.
 
                                 ARTICLE TWELVE
 
                                 SINKING FUNDS
 
     Section 1201.  Applicability of Article.
 
     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of a series, except as otherwise permitted or
required by any form of Security of such series issued pursuant to this
Indenture.
 
     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 such 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 may, in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of such series to be made pursuant to the
terms of such Securities as provided for by the terms of such series (1) deliver
Outstanding Securities of such series (other than any of such Securities
previously called for redemption or any of such Securities in respect of which
cash shall have been released to the Company), together in the case of any
Bearer Securities of such series with all unmatured Coupons appertaining
thereto, and (2) apply as a credit Securities of such series which have been
redeemed either at the election of the Company pursuant to the terms of such
series of Securities or through the application of permitted optional sinking
fund payments pursuant to the terms of such Securities or which have been
surrendered for conversion pursuant to Article Sixteen, provided that such
series of 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.
If as a result of the delivery or credit of Securities of any series in lieu of
cash payments pursuant to this Section 1202, the principal amount of Securities
of such series to be redeemed in order to exhaust the aforesaid cash payment
shall be less than $100,000, the Trustee need not call Securities of such series
for redemption, except upon Company Request, and such cash payment shall be held
by the Trustee or a Paying Agent and applied to the next succeeding sinking fund
payment, provided, however, that the Trustee or such Paying Agent shall at the
request of the
 
                                       45
<PAGE>   53
 
Company from time to time pay over and deliver to the Company any cash payment
so being held by the Trustee or such Paying Agent upon delivery by the Company
to the Trustee of Securities of that series purchased by the Company having an
unpaid principal amount equal to the cash payment requested to be released to
the Company.
 
     Section 1203.  Redemption of Securities for Sinking Fund.
 
     Not less than 75 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 mandatory 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 of
Securities of that series pursuant to Section 1202, the basis for any such
credit, and the optional amount, if any, to be added in cash to the next ensuing
mandatory sinking fund payment, and will also deliver to the Trustee any
Securities to be so credited and not theretofore delivered. If such Officers'
Certificate shall specify an optional amount to be added in cash to the next
ensuing mandatory sinking fund payment, the Company shall thereupon be obligated
to pay the amount therein specified. Not less than 60 days before each such
sinking fund payment date the Trustee shall select the Securities to be redeemed
upon such sinking fund payment date in the manner specified in Section 1103 and
cause notice of the redemption thereof to be given in the name of and at the
expense of the Company in the manner provided in Section 1104. Such notice
having been duly given, the redemption of such Securities shall be made upon the
terms and in the manner stated in Sections 1106 and 1107.
 
                                ARTICLE THIRTEEN
                       REPAYMENT AT THE OPTION OF HOLDERS
 
     Section 1301.  Applicability of Article.
 
     Securities of any series which are repayable at the option of the Holders
thereof before their Stated Maturity shall be repaid in accordance with the
terms of the Securities of such series. The repayment of any principal amount of
Securities pursuant to such option of the Holder to require repayment of
Securities before their Stated Maturity, for purposes of Section 309, shall not
operate as a payment, redemption or satisfaction of the indebtedness represented
by such Securities unless and until the Company, at its option, shall deliver or
surrender the same to the Trustee with a directive that such Securities be
cancelled. Notwithstanding anything to the contrary contained in this Article
Thirteen, in connection with any repayment of Securities, the Company may
arrange for the purchase of any Securities by an agreement with one or more
investment bankers or other purchasers to purchase such Securities by paying to
the Holders of such Securities on or before the close of business on the
repayment date an amount not less than the repayment price payable by the
Company on repayment of such Securities, and the obligation of the Company to
pay the repayment price of such Securities shall be satisfied and discharged to
the extent such payment is so paid by such purchasers.
 
                                ARTICLE FOURTEEN

     Section 1401.  Purposes for Which Meetings May Be Called.
 
     A meeting of Holders of Securities of any series may be called at any time
and from time to time pursuant to this Article to make, give or take any

action provided by this Indenture to be made, given or taken by Holders of
Securities of such series.
 
     Section 1402.  Call, Notice and Place of Meetings.

any series for any purpose specified in Section 1401, to be held at such time

Securities of such series are to be issued as Bearer Securities, in London, as
the Trustee shall
 
                                       46
<PAGE>   54
 
determine. Notice of every meeting of Holders of Securities of any series,
setting forth the time and the place of such meeting and in general terms the
action proposed to be taken at such meeting, shall be given, in the manner
provided in Section 106, not less than 21 nor more than 180 days prior to the

series shall have requested the Trustee to call a meeting of the Holders of
Securities of such series for any purpose specified in Section 1401, by written
request setting forth in reasonable detail the action proposed to be taken at
the meeting, and the Trustee shall not have mailed or made the first publication
of the notice of such meeting within 21 days after receipt of such request or
shall not thereafter proceed to cause the meeting to be held as provided herein,
then the Company or the Holders of Securities of such series in the amount above
specified, as the case may be, may determine the time and the place in the
Borough of Manhattan, The City of New York, or, if Securities of such series are
to be issued as Bearer Securities, in London for such meeting and may call such
meeting for such purposes by giving notice thereof as provided in subsection (a)
of this Section.
 
     Section 1403.  Persons Entitled to Vote at Meetings.

     Section 1404.  Quorum; Action.
 
     The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for a meeting of
Holders of Securities of such series. In the absence of a quorum within 30

such meeting. In the absence of a quorum at any such adjourned meeting, such
adjourned meeting may be further adjourned for a period of not less than 10 days

may be made, given or taken by the Holders of a specified percentage, which is
less than a majority, in principal amount of the Outstanding Securities of a
series may be adopted at a meeting or an adjourned meeting duly reconvened and

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

     Section 1405. Determination of Voting Rights; Conduct and Adjournment of
                   Meetings.
 
     (a) Notwithstanding any other provisions of this Indenture, the Trustee may
make such reasonable regulations as it may deem advisable for any meeting of

Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate.
Except as otherwise permitted or required by any such regulations, the holding

appointment of any proxy shall be proved in the manner specified in Section 104
or by having the signature of the person executing the proxy witnessed or
guaranteed by any trust company, bank or banker authorized by Section 104 to

written instruments appointing proxies, regular on their face, may be presumed
valid and genuine without the proof specified in Section 104 or other proof.
 
     (b) The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of Securities as provided in Section 1402(b), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman. A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.
 
     (c) At any meeting each Holder of a Security of such series or proxy shall
be entitled to one vote for each $1,000 principal amount of Securities of such
series held or represented by him; provided, however, that no vote shall be cast
or counted at any meeting in respect of any Security challenged as not
Outstanding and ruled by the chairman of the meeting to be not Outstanding. The
chairman of the meeting shall have no right to vote, except as a Holder of a
Security of such series or proxy.
 
     (d) Any meeting of Holders of Securities of any series duly called pursuant

Securities of any series shall be by written ballots on which shall be

permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in triplicate of all votes cast at the meeting. A record, at least in
triplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 1402 and, if
applicable, Section 1404. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

                                 SUBORDINATION
 
     Section 1501. Securities Subordinated to Senior Indebtedness.
 
     The Company covenants and agrees, and each Holder of Securities, by his
acceptance thereof, likewise covenants and agrees, that the indebtedness
evidenced by the Securities and the payment of the principal of
 
                                       48
<PAGE>   56
 
(and premium, if any) and interest and any Additional Amounts payable in respect
thereof is hereby expressly subordinated, to the extent and in the manner
hereinafter set forth, in right of payment to the prior payment in full of
Senior Indebtedness.
 
     Anything in this Indenture or in the Securities of any series to the
contrary notwithstanding, the indebtedness evidenced by the Securities shall be
subordinate and junior in right of payment, to the extent and in the manner
hereinafter set forth, to all Senior Indebtedness:
 
          (a) In the event of any insolvency or bankruptcy proceedings, and any
     receivership, liquidation, reorganization, arrangement or other similar
     proceedings in connection therewith, relative to the Company or to its
     property, and in the event of any proceedings for voluntary liquidation,
     dissolution or other winding-up of the Company, whether or not involving
     insolvency or bankruptcy, then the holders of Senior Indebtedness shall be
     entitled to receive payment in full of all principal, premium and interest
     on all Senior Indebtedness before the Holders of the Securities are
     entitled to receive any payment on account of principal, premium, if any,
     interest or Additional Amounts upon the Securities, and to that end (but
     subject to the power of a court of competent jurisdiction to make other
     equitable provisions reflecting the rights conferred in the Securities upon
     Senior Indebtedness and the Holders thereof with respect to the
     subordinated indebtedness represented by the Securities and the Holders
     hereof by a lawful plan of reorganization under applicable bankruptcy law)
     the holders of Senior Indebtedness shall be entitled to receive for
     application in payment thereof any payment or distribution of any kind or
     character, whether in cash or property or securities, which may be payable
     or deliverable in any such proceedings in respect of the Securities after
     giving effect to any concurrent payment or distribution in respect of such
     Senior Indebtedness, except securities which are subordinate and junior in
     right of payment to the payment of all Senior Indebtedness then
     outstanding;
 
          (b) In the event that any Security of any series is declared or
     otherwise becomes due and payable before its expressed maturity because of
     the occurrence of an Event of Default hereunder (under circumstances when
     the provisions of the foregoing clause (a) or the following clause (c)
     shall not be applicable), the holders of Senior Indebtedness outstanding at
     the time such Security so becomes due and payable because of such
     occurrence of an Event of Default hereunder shall, so long as such
     declaration has not been rescinded and annulled pursuant to Section 502, be
     entitled to receive payment in full of all principal of, and premium and
     interest on, all such Senior Indebtedness before the Holders of the
     Securities of such series are entitled to receive any payment on account of
     principal of, premium, if any, or interest and Additional Amounts on the
     Securities of such series; provided, that nothing herein shall prevent the
     Holders of Securities from seeking any remedy allowed at law or at equity
     so long as any judgment or decree obtained thereby makes provision for
     enforcing this clause; and
 
          (c) In the event that any default shall occur and be continuing with
     respect to any Senior Indebtedness permitting the holders of such Senior
     Indebtedness to accelerate the maturity thereof, if either (i) notice of
     such default, in writing or by telegram, shall have been given to the
     Company and to the Trustee, provided that judicial proceedings shall be
     commenced in respect of such default within 180 days in the case of a
     default in payment of principal or interest and within 90 days in the case
     of any other default after the giving of such notice, and provided, further
     that only one such notice shall be given pursuant to this Section 1501(c)
     in any twelve months period, or (ii) judicial proceedings shall be pending
     in respect of such default, the Holders of the Securities and the Trustee
     for their benefit shall not be entitled to receive any payment on account
     of principal, premium, if any, or interest and Additional Amounts thereon
     (including any such payment which would cause such default) unless payment
     in full of all principal of, and premium and interest on, such Senior
     Indebtedness shall have been made or provided for. The Trustee, forthwith
     upon receipt of any notice received by it pursuant to this Section 1501(c),
     shall, as soon as practicable, send a notice thereof to each Holder of
     Securities at the time outstanding as the names and addresses of such
     Holders appear on the Security Register and, in the case of Bearer
     Securities, in accordance with the provisions of Section 106 of this
     Indenture.
 
     In case despite the foregoing provisions, any payment or distribution
shall, in any such event, be paid or delivered to any Holder of the Securities
or to the Trustee for their benefit before all Senior Indebtedness shall
 
                                       49
<PAGE>   57
 
have been paid in full, such payment or distribution shall be held in trust for
and so paid and delivered to the holders of Senior Indebtedness (or their duly
authorized representatives) until all Senior Indebtedness shall have been paid
in full.
 
     The Company shall give written notice to the Trustee within five days after
the occurrence of any insolvency, bankruptcy, receivership, liquidation,
reorganization, arrangement or similar proceeding of the Company within the
meaning of this Section 1501.
 
     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 or representative on behalf of such holder) to establish that such
a notice has been given by a holder of Senior Indebtedness (or a trustee or
representative on behalf of such holder). 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 to participate in any
payment or distribution pursuant to this Section 1501, the Trustee may request
such Person to furnish evidence to the reasonable satisfaction of the Trustee as
to the amount of Senior Indebtedness held by such Person, as to the extent to
which such Person is entitled to participate in such payment or distribution,
and as to other facts pertinent to the rights of such Person under this Section
1501, and if such evidence is not furnished, the Trustee may defer any payment
to such Person pending judicial determination as to the right of such person to
receive such payment.
 
     Section 1502.  Subrogation.
 
     Subject to the payment in full of all Senior Indebtedness to which the
indebtedness evidenced by the Securities is in the circumstances subordinated as
provided in Section 1501, the Holders of the Securities shall be subrogated to
the rights of the holders of such Senior Indebtedness to receive payments or
distributions of cash, property or securities of the Company applicable to such
Senior Indebtedness until all amounts owing on the Securities shall be paid in
full, and, as between the Company, its creditors other than holders of such
Senior Indebtedness, and the Holders of the Securities, no such payment or
distribution made to the holders of such Senior Indebtedness by virtue of this
Article which otherwise would have been made to the Holders of the Securities
shall be deemed to be a payment by the Company on account of such Senior
Indebtedness, it being understood that the provisions of this Article Fifteen
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 the Senior
Indebtedness, on the other hand.
 
     Section 1503.  Obligation of Company Unconditional.
 
     Nothing contained in this Article Fifteen or elsewhere in this Indenture or
in the Securities is intended to or shall impair, as between the Company, its
creditors other than the holders of Senior Indebtedness and the Holders of the
Securities, the obligation of the Company which is absolute and unconditional,
to pay to the Holders of the Securities the principal of (and premium, if any),
interest on, or any Additional Amounts with respect to, the Securities as and
when the same shall become due and payable in accordance with their terms, or is
intended to or shall affect the relative rights of the Holders of the Securities
and creditors of the Company other than the holders of Senior Indebtedness nor
shall anything herein or therein 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
Fifteen of the holders of Senior Indebtedness in respect of cash, property or
securities of the Company received upon the exercise of any such remedy.
 
     Upon any payment or distribution of assets of the Company referred to in
this Article Fifteen, the Trustee, subject to the provisions of Section 315(a)
through 315(d) of the Trust Indenture Act, and the Holders of the Securities
shall be entitled to rely upon any order or decree made by any court of
competent jurisdiction in which any such dissolution, winding up, liquidation or
reorganization proceeding affecting the affairs of the Company is pending or
upon a certificate of the trustee in bankruptcy, receiver, assignee for the
benefit of creditors, liquidating trustee or agent or other person making any
payment or distribution, delivered to the Trustee or to the Holders of the
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
 
                                       50
<PAGE>   58
 
the Company the amount thereof or payable thereon, the amount paid or
distributed thereon and all other facts pertinent thereto or to this Article
Fifteen.
 
     Section 1504.  Payments on Securities Permitted.
 
     Nothing contained in this Article Fifteen or elsewhere in this Indenture,
or in any of the Securities, shall affect the obligation of the Company to make,
or prevent the Company from making payment of the principal of (or premium, if
any), interest or any Additional Amounts on the Securities in accordance with
the provisions hereof and thereof, except as otherwise provided in this Article
Fifteen.
 
     Section 1505.  Effectuation of Subordination by Trustee.
 
     Each Holder of Securities, by his acceptance thereof, authorizes and
directs the Trustee in his behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article Fifteen and
appoints the Trustee his attorney-in-fact for any and all such purposes.
 
     Section 1506.  Knowledge of Trustee.
 
     Notwithstanding the provisions of this Article Fifteen or any other
provisions 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 of
monies to or by the Trustee, or the taking of any other action by the Trustee,
unless and until the Trustee shall have received written notice thereof from the
Company, any Holder of the Securities, any paying or conversion agent of the
Company or the holder or representative of any class of Senior Indebtedness;
provided however, that if at least two Business Days prior to the date upon
which by the terms hereof any such monies may become payable for any purpose the
Trustee shall not have received with respect to such monies the notice provided
for in this Section 1506, then, anything herein contained to the contrary
notwithstanding, the Trustee shall have full power and authority to receive such
monies and to apply the same to the purpose for which they were received, and
shall not be affected by any notice to the contrary, which may be received by it
on or after the date upon which such monies become due and payable.
 
     Section 1507.  Trustee's Relation to Senior Indebtedness.
 
     Except as otherwise provided in the Trust Indenture Act, the Trustee shall
be entitled to all the rights set forth in this Article with respect to any
Senior Indebtedness at the time held by it, to the same extent as any other
holder of Senior Indebtedness, and nothing in this Indenture shall deprive the
Trustee of any of its rights as such holder. Notwithstanding anything in this
Indenture or in the Securities of any series, nothing in this Article Fifteen
shall apply to claims of or payment to the Trustee under or pursuant to Sections
506 and 606.
 
     With respect to holders of Senior Indebtedness, the Trustee undertakes to
perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article Fifteen, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee. The Trustee shall not be deemed to owe
any fiduciary duty to the holders of Senior Indebtedness and the Trustee shall
not be liable to any holder of Senior Indebtedness if it shall pay over or
deliver to Holders, the Company or any other Person monies or assets to which
any holder of Senior Indebtedness shall be entitled by virtue of this Article
Fifteen or otherwise.
 
     Section 1508.  Rights of Holders of Senior Indebtedness Not Impaired.
 
     No right of any present or future holder of any Senior Indebtedness to
enforce the subordination herein shall at any time or in any way be prejudiced
or impaired by any act or failure to act on the part of the Company or by any
non-compliance by the Company with the terms, provisions or covenants of this
Indenture, regardless of any knowledge thereof any such holder may have or be
otherwise charged with.

                                ARTICLE SIXTEEN
 
                                   CONVERSION
 
     Section 1601.  Conversion Privilege.
 
     Subject to and upon compliance with the provisions of this Article Sixteen
and the terms of the Convertible Securities of the series proposed to be
converted, at the option of the Holder, any Convertible Security or any portion
of the principal amount thereof which is $1,000 or an integral multiple thereof,
may be converted into shares of Common Stock, as said shares shall be
constituted at the Date of Conversion, at the Conversion Price for such
Convertible Securities of such series in effect at the Date of Conversion.
 
     Section 1602.  Manner of Exercise of Conversion Privilege.
 
     In order to exercise the conversion privilege, the Holder of any
Convertible Security to be converted shall surrender such Convertible Security
to the Company at its office or agency in the Borough of Manhattan, The City of
New York, together with the conversion notice in the form provided on the
Securities (or separate written notice) duly executed, and, if so required by
the Company or the [Trustee] [Security Registrar], accompanied by instruments of
transfer, in form satisfactory to the Company and to the [Trustee], [Security
Registrar] duly executed by the Holder or by his duly authorized attorney in
writing. Any Registered Convertible Security so surrendered during the period
from the close of business on the Regular Record Date preceding an Interest
Payment Date for such Registered Convertible Security to the opening of business
on such Interest Payment Date shall (unless any such Registered Convertible
Security or the portion thereof being converted shall have been called for
redemption on a Redemption Date during such period, in which event no interest
shall be payable with respect to such Registered Convertible Security or portion
thereof, as the case may be, following such Redemption Date) also be accompanied
by payment in New York Clearing House funds or other funds acceptable to the
Company of an amount equal to the interest payable on such Interest Payment Date
on the principal amount of such Registered Convertible Security then being
converted; provided, however, that no such payment need be made if there shall
exist, at the time of conversion, a default in the payment of interest on the
Convertible Securities of such series. Except as provided in the immediately
preceding sentence, no adjustment shall be made for interest accrued on any
Convertible Security that shall be converted or for dividends on any shares of
Common Stock that shall be delivered upon the conversion of such Convertible
Securities. The funds so delivered to such office or agency shall be paid to the
Company on or after such Interest Payment Date, unless the Company shall default
in the payment of the interest due on such Interest Payment Date, in which event
such funds shall be repaid to the Person who delivered the same. As promptly as
practicable after the surrender of any Convertible Security for conversion as
aforesaid, the Company shall deliver at said office or agency to such Holder, or
on his written order, a certificate or certificates for the number of full
shares deliverable upon the conversion of such Convertible Security or portion
thereof and a check or cash in respect of any fraction of a share of Common
Stock otherwise deliverable upon such conversion, all as provided in this
Article Sixteen, together with a Convertible Security or Convertible Securities
of the same series in principal amount equal to the unconverted and unredeemed
portion, if any, of the Convertible Security so converted in accordance with
Section 305 hereof. Such conversion shall be deemed to have been effected on the
Date of Conversion and the Person or Persons in whose name or names any
certificate or certificates for shares of Common Stock shall be deliverable upon
such conversion shall be deemed to have become on said Date the Holder or
Holders of record of the shares represented thereby, provided, however, at any
such surrender on any date when the stock transfer books of the Company shall be
closed shall constitute the Person or Persons in whose name or names the
certificates are to be delivered as the record Holder or Holders thereof for all
purposes on the next succeeding day on which such stock transfer books are open,
but such conversion shall be at the Conversion Price in effect on the date of
such surrender.
 
     Section 1603.  Cash Adjustment Upon Conversion.
 
     The Company shall not be required to deliver fractions of shares of Common
Stock upon conversions of Convertible Securities. If more than one Convertible
Security shall be surrendered for conversion at one time by the same Holder, the
number of full shares which shall be deliverable upon conversion thereof shall
be
 
                                       52
<PAGE>   60
 
computed on the basis of the aggregate principal amount of the Securities so
surrendered. If any fractional interest in a share of Common Stock would be
deliverable upon the conversion of any Convertible Security or Securities, the
Company shall make an adjustment therefor in cash equal to the current market
value of such fractional interest computed to the nearest cent either on the
basis of the last reported sale price regular way of the Common Stock on the New
York Exchange (or, if not listed on the New York Exchange, then on such other
exchange on which the shares of Common Stock are listed as the Company may
designate) on the last Business Day prior to the Date of Conversion or, if there
shall not have been a sale on such last Business Day, on the basis of the
average of the bid and asked quotations therefor on such exchange on such last
Business Day or, if the Common Stock shall not then be listed on any exchange,
at the highest bid quotation in the over-the-counter market on such last
Business Day as reported by the National Association of Securities Dealers
through NASDAQ, its automated system for reporting quotes, or its successor or
such other generally accepted source of publicly reported bid and asked
quotations as the Company may reasonably designate.
 
     Section 1604.  Conversion Price.
 
     The Conversion Price applicable to any series of Convertible Securities
shall be the initial Conversion Price set forth in the Officers' Certificate or
supplemental indenture establishing such series adjusted as provided in this
Article Sixteen.
 
     Section 1605.  Adjustment of Conversion Price.
 
     The Conversion Price applicable to any series of Convertible Securities
shall be adjusted from time to time as follows:
 
          (a) In case the Company shall, at any time or from time to time while
     the Securities of any series are outstanding, (i) pay a dividend on its
     Common Stock in shares of Common Stock, (ii) subdivide its outstanding
     shares of Common Stock into a larger number of shares, or (iii) combine its
     outstanding Common Stock into a smaller number of shares, the Conversion
     Price for such series in effect immediately prior thereto shall be adjusted
     so that the Holder of any Security of such series thereafter surrendered
     for conversion shall be entitled to receive the number of shares of Common
     Stock or other securities of the Company which he would have owned or have
     been entitled to receive after the happening of any of the events described
     above, had such Convertible Security of such series been converted
     immediately prior to the happening of such event. An adjustment made
     pursuant to this subdivision (a) shall be come effective, in the case of a
     dividend, on the payment date retroactively to immediately after the
     opening of business on the day following the record date for the
     determination of shareholders entitled to receive such dividend, subject to
     the provisions of paragraph (g) of this Section 1605, and shall become
     effective in the case of a subdivision or combination immediately after the
     opening of business on the day following the day when such subdivision or
     combination, as the case may be, becomes effective.
 
          (b) In case the Company shall, at any time or from time to time while
     the Convertible Securities of any series are outstanding, issue rights or
     warrants to all holders of its shares of Common Stock entitling them (for a
     period expiring within 45 days of the record date mentioned below) to
     subscribe for or purchase shares of Common Stock at a price per share less
     than the current market price per share of Common Stock (as defined in
     paragraph (d) below) at such record date, the Conversion Price of any
     series of Convertible Securities in effect immediately prior to the
     issuance of such rights or warrants shall be adjusted as follows: the
     number of shares of Common Stock into which $1,000 principal amount of
     Convertible Securities of such series was theretofore convertible shall be
     multiplied by a fraction, of which the numerator shall be the number of
     shares of Common Stock outstanding immediately prior to such record date
     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 immediately prior to such record date
     plus the number of shares which the aggregate offering price of the total
     number of shares so offered would purchase at such current market price;
     and the Conversion Price for such series of Convertible Securities shall be
     adjusted by dividing $1,000 by the new number of shares into which $1,000
     principal amount of Securities of such series shall be convertible as
     aforesaid. Such adjustment shall become effective on the date of such
     issuance retroactively to immediately after the
 
                                       53
<PAGE>   61
 
     opening of business on the day following the record date for the
     determination of shareholders entitled to receive such rights or warrants,
     subject to the provisions of paragraph (g) of this Section 1605. In
     determining whether any rights or warrants entitle the holders to subscribe
     for or purchase shares of Common Stock at less than such current market
     price, and in determining the aggregate offering price of such shares,
     there shall be taken into account any consideration received by the Company
     for such rights or warrants, the value of such consideration, if other than
     cash, to be determined by the Board of Directors.
 
          (c) In case the Company shall, at any time from time to time while the
     Convertible Securities of any series are outstanding, distribute to all
     holders of shares of its Common Stock evidences of its indebtedness or
     securities or assets (excluding cash dividends or cash distributions
     payable out of consolidated net earnings or retained earnings) or rights or
     warrants to subscribe for shares of Common Stock at a price per share less
     than the current market price per share of Common Stock, determined in the
     manner set forth in paragraph (d) below, but excluding rights or warrants
     referred to in paragraph (b) above, the Conversion Price for such series of
     Convertible Securities in effect immediately prior to such distribution
     shall be adjusted by multiplying the number of shares of Common Stock into
     which $1,000 principal amount of Convertible Securities of such series of
     Convertible Securities was theretofore convertible by a fraction, of which
     the numerator shall be the current market price per share of Common Stock
     (as defined in paragraph (d) below) on the record date for such
     distribution, and of which the denominator shall be such current market
     price per share of the Common Stock, less the then fair market value (as
     determined by the Board of Directors of the Company, whose determination
     shall be conclusive) of the portion of such evidences of indebtedness,
     securities or assets or of such subscription rights or warrants so
     distributed applicable to one share of Common Stock; and the Conversion
     Price for such series of Convertible Securities shall be adjusted by
     dividing $1,000 by the new number of shares into which $1,000 principal
     amount of Convertible Securities of such series shall be convertible as
     aforesaid. Such adjustment shall become effective on the date of such
     distribution retroactively to immediately after the opening of business on
     the day following the record date for the determination of shareholders
     entitled to receive such distribution, subject to the provisions of
     paragraph (g) of this Section 1605. For the purposes of this paragraph (c)
     consolidated net earnings or retained earnings shall be computed by adding
     thereto all charges against retained earnings on account of dividends paid
     in shares of Common Stock in respect of which the Conversion Price has been
     adjusted, all as determined by Independent Public Accountants, whose
     determination shall be conclusive.
 
          (d) For the purpose of any computation under paragraphs (b) and (c)
     above, the current market price per share of Common Stock at any date shall
     be deemed to be the average of the market values of the shares of Common
     Stock for the ten consecutive Business Days immediately preceding the day
     in question. The market value of the Common Stock for each day shall be
     determined as provided in Section 1603 hereof.
 
          (e) The Company may make such reductions in the Conversion Price for
     any series of Convertible Securities, in addition to those required by
     paragraphs (a), (b) and (c) of this Section as it considers to be advisable
     in order that any event treated for Federal income tax purposes as a
     dividend of stock or stock rights shall not be taxable to the recipients.
 
          (f) Except as herein otherwise provided, no adjustment in the
     Conversion Price for any series of Convertible Securities shall be made by
     reason of the issuance, in exchange for cash, property or services, of
     shares of Common Stock, or any securities convertible into or exchangeable
     for shares of Common Stock, or carrying the right to purchase any of the
     foregoing.
 
          (g) If the Company shall take a record of the holders of its shares of
     Common Stock for the purpose of entitling them to receive any dividend or
     any subscription or purchase rights or any distribution and shall,
     thereafter and before the distribution to shareholders of any such
     dividend, subscription or purchase rights or distribution, legally abandon
     its plan to pay or deliver such dividend, subscription or purchase rights
     or distribution, then no adjustment of the Conversion Price for any series
     of Convertible Securities shall be required by reason of the taking of such
     record.
 
                                       54
<PAGE>   62
 
          (h) No adjustment in the Conversion Price for any series of
     Convertible Securities shall be required unless such adjustment would
     require an increase or decrease of at least 1% in such price; provided,
     however, that any adjustments which by reason of this paragraph (h) are not
     required to be made shall be carried forward and taken into account in any
     subsequent adjustment. All calculations under this Article Sixteen shall be
     made to the nearest cent or to the nearest one-hundredth of a share, as the
     case may be.
 
          (i) Whenever the Conversion Price for any series of Convertible
     Securities is adjusted as herein provided, the Company shall (i) forthwith
     place on file at the Corporate Trust Office an Officers' Certificate
     showing in detail the facts requiring such adjustment and the Conversion
     Price after such adjustment and shall exhibit the same from time to time to
     any Holder of Convertible Securities of such series desiring an inspection
     thereof, and (ii) cause a notice stating that such adjustment has been
     effected and the adjusted Conversion Price to be mailed to the Holders of
     Registered Convertible Securities of such series at their last addresses as
     they shall appear on the Security Register.
 
          (j) The Company may delete, modify or vary any of the provisions
     applicable to conversion of the Convertible Securities of any series, or
     may add new provisions applicable thereto, all as may be contained in the
     Board Resolutions and Officers' Certificate or supplemental indenture
     establishing such series.
 
     Section 1606.  Effect of Reclassifications, Consolidations, Mergers or
Sales on Conversion Privilege.
 
     In case of any reclassification or change of outstanding shares of the
class of Common Stock issuable upon conversion of the Convertible Securities
(other than a change in par value, or from par value to no par value, or from no
par value to par value, or as a result of a subdivision or combination), or in
case of any merger or consolidation of the Company with one or more other
corporations (other than a merger or consolidation in which the Company is the
continuing corporation and which does not result in any reclassification or
change of outstanding shares of Common Stock issuable upon conversion of the
Securities), or in case of the merger of the Company into another corporation,
or in case of any sale or conveyance to another corporation of the property of
the Company as an entirety or substantially as an entirety, the Holder of each
Convertible Security then outstanding shall have the right to convert such
Convertible Security into the kind and amount of shares of capital stock or
other securities and property, including cash, receivable upon such
reclassification, change, consolidation, merger, sale or conveyance by a holder
of the number of shares of Common Stock into which such Convertible Security
might have been converted immediately prior to such reclassification, change,
consolidation, merger, sale or conveyance. In any such case the Company, or such
successor or purchasing corporation, as the case may be, shall execute with the
Trustee one or more supplemental indentures (which shall conform to the Trust
Indenture Act of 1939 as in force at the date of the execution of such
supplemental indenture) containing provisions to the effect set forth above in
this Section 1606 and providing further for adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Article
Sixteen; and any such adjustment which shall be approved by the Board of
Directors and set forth in such supplemental indenture or supplemental
indentures shall be conclusive for all purposes of this Section, and the Trustee
shall not be under any responsibility to determine the correctness of any
provision contained in such supplemental indenture or supplemental indentures
relating to either the kind or amount of shares of stock or securities or
property or cash receivable by Holders of Securities of any series upon the
conversion of their Convertible Securities after any such reclassification,
change, consolidation, merger, sale or conveyance.
 
     The above provisions of this Section 1606 shall similarly apply to
successive reclassifications, changes, consolidations, mergers, sales and
conveyances.
 
     Section 1607.  Taxes on Conversions.
 
     The issue of stock certificates on conversions of Convertible Securities
shall be made without charge to the converting Holder of Convertible Securities
for any tax in respect of the issue thereof. The Company shall not, however, be
required to pay any tax which may be payable in respect of any transfer involved
in the issue and delivery of shares in any name other than that of the Holder of
any Registered Convertible Security
 
                                       55
<PAGE>   63
 
converted, and the Company shall not be required to issue or deliver any such
stock certificate unless and until the Person or Persons requesting the issue
thereof shall have paid to the Company the amount of such tax or shall have
established to the satisfaction of the Company that such tax has been paid.
 
     Section 1608.  Company to Reserve Common Stock.
 
     The Company shall at all times reserve and keep available out of the
aggregate of its authorized but unissued shares or its issued shares held in its
treasury, or both, for the purpose of effecting the conversion of the
Securities, such number of its duly authorized shares of Common Stock as shall
from time to time be sufficient to effect the conversion of all outstanding
Securities.
 
     If any shares of Common Stock reserved or to be reserved for the purpose of
conversion of Securities hereunder require registration with or approval of any
governmental authority under any Federal or State law before such shares may be
validly delivered upon conversion, then the Company covenants that it will in
good faith and as expeditiously as possible endeavor to secure registration or
approval, as the case may be.
 
     The Company covenants that all shares of Common Stock which may be
delivered upon conversion of Convertible Securities shall upon delivery be fully
paid and nonassessable by the Company and free from all taxes, liens and charges
with respect to the issue or delivery thereof.
 
     Section 1609.  Disclaimer by Trustee of Responsibility for Certain Matters.
 
     Neither the Trustee nor any conversion agent shall at any time be under any
duty or responsibility to any Holder of Convertible Securities of any series to
determine whether any facts exist which may require any adjustment of the
Conversion Price for such series, or with respect to the nature or extent of any
such adjustment when made, or with respect to the method employed, or herein or
in any supplemental indenture provided to be employed, in making the same,
subject, however, to the provisions of Sections 315(a) through 315(d) of the
Trust Indenture Act. Neither the Trustee nor any conversion agent shall be
accountable with respect to the validity or value (or the kind or amount) of any
shares of Common Stock, or of any securities or property or cash which may at
any time be issued or delivered upon the conversion of any Convertible Security;
and neither of them makes any representation with respect thereto. Neither the
Trustee nor any conversion agent shall be responsible for any failure of the
Company to make any cash payment or to issue, transfer or deliver any shares of
Common Stock or stock certificates or other securities or property upon the
surrender of any Security for the purpose of conversion or, subject to Sections
315(a) through 315(d) of the Trust Indenture Act, to comply with any of the
covenants of the Company contained in this Article Sixteen.
 
     Section 1610.  Company to Give Notice of Certain Events.
 
     In the event
 
          (1) that the Company shall pay any dividend or make any distribution
     to the holders of shares of Common Stock otherwise than in cash charged
     against consolidated net earnings or retained earnings of the Company and
     its consolidated net earnings or retained earnings of the Company and its
     consolidated subsidiaries or in Common Stock; or
 
          (2) that the Company shall offer for subscription or purchase, pro
     rata, to the holders of shares of Common Stock any additional shares of
     stock of any class or any securities convertible into or exchangeable for
     stock of any class; or
 
          (3) of any reclassification or change of outstanding shares of the
     class of Common Stock issuable upon the conversion of the Securities (other

                        % SUBORDINATED NOTE DUE
 
     This Note is one of a duly authorized issue of Securities of the Company,
issued and to be issued in one or more series under the subordinated indenture
(herein called the "Indenture"), dated as of August             , 1995 between
the Company and CHEMICAL BANK, Trustee (herein called the "Trustee", which term
includes any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights thereunder of the Company, the Trustee and the Holders of the
Notes, and of the terms upon which the Notes are, and are to be, authenticated
and delivered.
 
     The indebtedness evidenced by the Notes is, to the extent and in the manner
provided in the Indenture, subordinate and subject in right of payment to the
prior payment in full of the principal of (and premium, if any) and interest and
Additional Amounts on all Senior Indebtedness as defined in the Indenture, and
this Security is issued subject to such provisions and each Holder of this Note,
by accepting the same, agrees to and shall be bound by such provisions, and
authorizes the Trustee in his behalf to take such action as may be necessary or
appropriate to effectuate such subordination as provided in the Indenture and
appoints the Trustee his attorney-in-fact for such purpose.
 
     Subject to certain limitations in the Indenture, if an Event of Default
occurs and is continuing, then the Trustee or the Holders of not less than 25%
in principal amount of the Outstanding Notes may declare the principal of all
the Notes to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by the Holders).
 
     Subject to certain exceptions requiring the consent of each Holder
affected, the Indenture or the Notes may be amended or supplemented with the
consent of the Holders of not less than a majority in principal amount of the
Outstanding Notes affected, and compliance by the Company with certain
provisions of the Indenture and any past default under the Indenture (except a
default in the payment of the principal of or interest on or Additional Amounts,
if any, with respect to the Notes or in respect of a covenant or provision which
under the terms of the Indenture cannot be modified or amended without the
consent of each Holder affected) may be waived with the consent of the Holders
of at least a majority in principal amount of the Outstanding Notes. Without
notice to or the consent of any Holder, the parties to the Indenture may amend
or supplement the Indenture or the Notes to, among other things, cure any
ambiguity, defect or inconsistency and provide for assumption of the Company's
obligations to the Holder by another Person.
 
     The Notes are also subject to redemption, at the option of the Company, in
whole, or from time to time in part, on             , 1998 and on any interest
payment date thereafter, on not less than 30 nor more than 60 days prior notice
given as provided in the Indenture, at a redemption price equal to 100% of the
principal amount of the Notes to be redeemed plus any accrued and unpaid
interest thereon to the date of redemption. If the Company elects to redeem less
than all of the Notes, the Trustee shall select the Notes to be redeemed by such
method as the Trustee shall deem fair and appropriate and which may provide for
the selection for redemption of portions of the principal amount of the Notes of
denominations larger than $1,000.
 
     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Note may be registered on the Security Register,
upon surrender of this Note for registration of transfer at the Corporate Trust
Office of the Trustee, or at such office or agency of the Company maintained for
that purpose, duly endorsed by, or accompanied by a written instrument of
transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or by his attorney duly authorized in writing,
and thereupon one or more new Notes of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.
 
     The Notes are issuable only in registered form without coupons in
denominations of $1,000 or any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, the Notes are
exchangeable for a like aggregate principal amount of Notes of this series of a
different authorized denomination, as requested by the Holder surrendering the
same.

     No service change shall be made for any registration of transfer or
exchange of Notes, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection herewith.
 
     Prior to due presentment of this Note for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Note is registered as the owner hereof for all
purposes, whether or not this Note be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.
 
     Beneficial interests in the Notes will be shown on, and transfers thereof
will be affected only through, records maintained by the Depositary and its
participants. Owners of beneficial interests in this Note will not be entitled
to receive Notes in definitive form and will not be considered Holders of Notes
unless the Depositary notifies the Company in writing that it is no longer
willing or able to act as a depositary or if the Depositary ceases to be a
clearing agency registered under the Securities Exchange Act of 1934, as
amended, or if the Company determines not to have the Notes represented by
Global Securities. In such circumstances, upon surrender by the Depositary or a
successor depositary of the global Securities, Notes in definitive form will be
issued in fully registered form without coupons, in minimum denominations of
$1,000 or any integral multiple thereof. Such definitive Notes shall be
registered in such name or names as the Depositary shall instruct the Trustee.
If definitive Notes are so delivered, the Company may make such changes to the
form of this Note as are necessary or appropriate to allow for the issuance of
such definitive Notes.
 
     All terms used in this Note which are defined in the Indenture shall have
the meanings assigned to them in the Indenture. The terms of the Notes include
those stated in the Indenture and those made part of the Indenture by reference
to the Trust Indenture Act of 1939, as amended. The Notes are subject to all
such terms, and Holders of Notes are referred to the Indenture, all indentures
supplemental thereto and said Act for a statement of such terms.

Ladies and Gentlemen:
 
     Reference is made to the Registration Statement on Form S-3 (the
"Registration Statement") to be filed by Firstar Corporation (the "Corporation")
with the Securities and Exchange Commission (the "Commission") pursuant to the
Securities Act of 1933, as amended (the "Securities Act"), relating to the
proposed offering of $100 million aggregate principal amount of Subordinated
Notes due 2000 (the "Notes") through Merrill Lynch & Co. and Robert W. Baird &
Co. Incorporated, as representatives of the several Underwriters as set forth in
the Prospectus included in the Registration Statement.
 
     As Senior Vice President and General Counsel of the Corporation, I am
familiar with the Corporation's Restated Articles of Incorporation and By-Laws,
as amended, and with its affairs. I have also examined, or caused to be examined
a signed copy of the Registration Statement, resolutions of the Corporation's
Board of Directors adopted on July 20, 1995 and such other proceedings,
documents and records as I have deemed necessary or appropriate to enable me to
render this opinion.
 
     Based on the foregoing, it is my opinion that:
 
     1. The Corporation is a corporation duly organized and validly existing
under the laws of the State of Wisconsin.
 
     2. When (a) the appropriate officers of the Corporation shall have taken
action to approve the final terms of the Notes, including fixing the interest
rate thereon, and terms of sale of the Notes; (b) the registration requirements
of the Securities Act and applicable Blue Sky and other state securities laws
have been complied with; (c) the proposed Indenture between the Corporation and
Chemical Bank, Trustee, pursuant to which the Notes are to be issued shall have
been duly executed and delivered and shall have been qualified under the Trust
Indenture Act of 1939, as amended; and (d) the Notes shall have been duly
executed, authenticated, issued and delivered against a payment therefor, the
Notes will thereupon be legally issued and binding obligations of the
Corporation.
 
     I consent to the use of this opinion as Exhibit 5 to the Registration
Statement, and I further consent to the use of my name in the Registration
Statement. In giving this consent, I do not admit that I am an "expert" within
the meaning of Section 11 of the Securities Act, or within the category of
persons whose consent is required by Section 7 of the Securities Act or the
rules and regulations of the Commission issued thereunder.
 
                                          Very truly yours,
 
                                          /s/ HOWARD H. HOPWOOD III
