                                 PNC BANK CORP.
 
     PNC is a bank holding company registered under the Bank Holding Company Act
of 1956, as amended (the "BHC Act"). PNC was incorporated under the laws of the
Commonwealth of Pennsylvania in 1983 with the consolidation of Pittsburgh
National Corporation and Provident National Corporation. Since 1983, PNC has
diversified its geographic presence and product capabilities through strategic
bank and nonbank acquisitions and the formation of various nonbank subsidiaries.
 
     PNC is one of the largest diversified financial service companies in the
United States. The Corporation operates through five lines of business: Consumer
Banking, Corporate Banking, Real Estate Banking, Mortgage Banking and Asset
Management. Each line of business focuses on specific customer segments and
offers financial products and services in PNC's primary geographic markets in
Pennsylvania, New Jersey, Delaware, Ohio and Kentucky and nationally through
retail distribution networks and alternative delivery channels. At June 30,
1997, the Corporation's consolidated assets, loans (net of unearned income),
deposits, and shareholders' equity were $72.0 billion, $53.5 billion, $45.2
billion and $5.4 billion, respectively.
 
     While the Corporation manages five lines of business, the corporate legal
structure consists of 10 subsidiary banks and over 110 active nonbank
subsidiaries. PNC Bank, National Association, headquartered in Pittsburgh,
Pennsylvania ("PNC Bank"), is the Corporation's principal bank subsidiary. At
June 30, 1997, PNC Bank had total assets of $57.5 billion, representing
approximately 80% of the Corporation's consolidated assets.
 
     PNC's principal executive offices are located at One PNC Plaza, 249 Fifth
Avenue, Pittsburgh, Pennsylvania 15222, and its telephone number is
(412)762-1553.
 
                                PNC FUNDING CORP
 
     PNC Funding is a wholly-owned indirect subsidiary of PNC. PNC Funding was
incorporated under the laws of the Commonwealth of Pennsylvania in 1972 and is
engaged in financing the activities of PNC and its subsidiaries through the
issuance of commercial paper and other debt guaranteed by PNC.
 
     PNC Funding's principal executive offices are located at 1600 Market
Street, Philadelphia, Pennsylvania 19101, and its telephone number is
(215)585-5000.
 
                   SUPERVISION, REGULATION AND OTHER MATTERS
 
     The Corporation and its subsidiaries are subject to extensive governmental
regulation. The coverage of the regulations range from activity, investment and
dividend limitations on the bank holding company and its subsidiaries to
consumer-related protections for loans, deposits, brokerage and mutual fund
customers. The following information is not intended to be an exhaustive
description of the statutes and regulations applicable to PNC. The discussion is
qualified in its entirety by reference to all particular statutory or regulatory
provisions. Additional information regarding supervision and regulation is
included in the incorporated documents. See "Incorporation of Certain Documents
by Reference."
 
     As a bank holding company registered under the BHC Act, PNC's primary bank
regulatory authority is the Board of Governors of the Federal Reserve System
(the "Federal Reserve"). Under Federal Reserve policy, a bank holding company is
expected to act as a source of strength to each of its subsidiary banks and to
commit resources to support each such bank. As a result of that policy, PNC may
be required to commit resources to its subsidiary banks in circumstances where
it might not otherwise do so. Moreover, the actions and policy directives of the
Federal Reserve determine to a significant degree the cost and the availability
of funds obtained from money market sources for lending and investing. The
Federal Reserve's policies and regulations also influence, directly and
indirectly, the rates of interest paid by commercial banks on their time and
savings deposits. The nature and impact on PNC of future changes in monetary and
other policies of the
 
                                        3
<PAGE>   5
 
Federal Reserve are not predictable, as such changes also depend on economic
conditions and domestic and foreign governmental policies, among other factors.
 
     PNC is a legal entity separate and distinct from PNC Funding, PNC Bank and
its other subsidiaries and affiliates. Such subsidiaries and affiliates are also
subject to supervision and examination by various federal and state regulatory
agencies, including the Office of the Comptroller of the Currency ("OCC") with
respect to PNC Bank. Because PNC is a holding company, its rights and the rights
of its creditors and shareholders, including the holders of the Securities, to
participate in the assets of any subsidiary upon the latter's liquidation or
recapitalization will be subject to the prior claims of the subsidiary's
creditors, except to the extent that PNC may itself be a creditor with
recognized claims against the subsidiary.
 
     PNC derives substantially all of its income from payment of dividends by
its bank and non-bank subsidiaries. There are various legal limitations on the
extent to which PNC's bank subsidiaries may extend credit, pay dividends or
otherwise supply funds to PNC. For example, the approval of the OCC is required
if total dividends by a national bank in any calendar year exceed net profits
(as defined) for that year combined with its retained profits for the preceding
two years. In addition, dividends for such a bank may not be paid in excess of
the bank's undivided profits. State-chartered bank subsidiaries are subject to
dividend limitations imposed by applicable state law. The approval of the Office
of Thrift Supervision may be required if total dividends declared by PNC's
savings association subsidiary in any calendar year exceed amounts specified in
that agency's regulations. In determining whether and to what extent to pay
dividends, each bank subsidiary must also consider the effect of dividend
payments on applicable risk-based capital and leverage requirements (as
described below) as well as policy statements of the federal regulatory agencies
that indicate that banking organizations should generally pay dividends out of
current operating earnings. Contractual restrictions may also limit the ability
to pay dividends, such as those contained in documentation relating to
mandatorily redeemable capital securities in the event of a default.
 
     The U.S. federal bank regulatory authorities have each adopted risk-based
capital guidelines to which the Corporation and its insured depository
institutions subsidiaries are subject. These guidelines are based on an
international agreement developed by the Basle Committee on Banking Regulations
and Supervisory Practices, which consists of representatives of central banks
and supervisory authorities in 12 countries including the United States of
America. The guidelines establish a systematic analytical framework that makes
regulatory capital requirements more sensitive to differences in risk profiles
among banking organizations, takes off-balance sheet exposures into explicit
account in assessing capital adequacy and minimizes disincentives to holding
liquid, low-risk assets. Risk-based assets are determined by allocating assets
and specified off-balance sheet commitments and exposures into four weighted
categories, with higher levels of capital being required for the categories
perceived as representing greater risk. From time to time, the federal
regulatory agencies propose amendments to and issue interpretations of their
risk-based capital guidelines and reporting instructions, which can affect
reported capital ratios and net risk-adjusted assets.
 
     Each of the Corporation's subsidiary banks is required to maintain a
minimum total risk-based ratio of 8%, of which half (4%) must be "Tier I"
capital. In addition, U.S. federal bank regulators have established leverage
ratio (Tier I capital to average total adjusted assets) guidelines providing for
a minimum leverage ratio of 3% for banks meeting certain specified criteria,
including excellent asset quality, high liquidity, low interest rate exposure
and the highest regulatory rating. Institutions not meeting these criteria are
expected to maintain a ratio which exceeds the 3% minimum by at least 100 to 200
basis points. The federal bank regulatory authorities may, however, set higher
capital requirements when a bank's particular circumstances warrant.
 
     The federal banking agencies possess broad powers to take corrective action
as deemed appropriate for an insured depository institution and its holding
companies. The extent of these powers depends upon whether the institution in
question is considered "well capitalized," "adequately capitalized,"
"undercapitalized," "significantly undercapitalized" or "critically
undercapitalized." Generally, as an institution is deemed to be less well
capitalized, the scope and severity of the agencies' powers increase. The
agencies' corrective powers can include, among other things, requiring an
insured financial institution to adopt a capital restoration plan which cannot
be approved unless guaranteed by the institution's parent holding company;
placing limits on asset
 
                                        4
<PAGE>   6
 
growth and restrictions on activities; placing restrictions on transactions with
affiliates; restricting the interest rates the institution may pay on deposits;
prohibiting the institution from accepting deposits from correspondent banks;
prohibiting the payment of principal or interest on subordinated debt;
prohibiting the holding company from making capital distributions without prior
regulatory approval; and, ultimately, appointing a receiver for the institution.
Business activities may also be influenced by an institution's capital
classification. For instance, only a "well capitalized" depository institution
may accept brokered deposits without prior regulatory approval and only an
"adequately capitalized" depository institution may accept brokered deposits
with prior regulatory approval. At June 30, 1997, each of the Corporation's
subsidiary banks exceeded the required ratios for classification as "well
capitalized."
 
     The deposits of the Corporation's subsidiary banks are insured by the
Federal Deposit Insurance Corporation (the "FDIC") and are subject to FDIC
insurance assessments. The amount of FDIC assessments paid by individual insured
depository institutions is based on their relative risk as measured by
regulatory capital ratios and certain other factors. Currently, the
Corporation's bank subsidiaries are not assessed any premium for deposits
insured by either the Bank Insurance Fund or by the Savings Association
Insurance Fund. The Corporation's bank subsidiaries, however, continue to pay
premiums based on deposit levels to service debt on bonds issued by a
governmental entity.
 
     Under U.S. federal law, a financial institution insured by the FDIC under
common ownership with a failed institution can be required to indemnify the FDIC
for its losses resulting from the insolvency of the failed institution, even if
such indemnification causes the affiliated institution also to become insolvent.
As a result, the Corporation's subsidiary banks could, under certain
circumstances, be obligated for the liabilities of its affiliates that are
FDIC-insured institutions. In addition, if any insured depository institution
becomes insolvent and the FDIC is appointed its conservator or receiver, the
FDIC may disaffirm or repudiate any contract or lease to which such institution
is a party, the performance of which is determined to be burdensome and the
disaffirmance or repudiation of which is determined to promote the orderly
administration of the institution's affairs. If federal law were construed to
permit the FDIC to apply these provisions to debt obligations of an insured
depository institution the result could be that such obligations would be
prepaid without premium even where by their terms they were not prepayable or
prepayable only with a premium. Federal law also accords the claims of a
receiver of an insured depository institution for administrative expenses and
the claims of holders of deposit liabilities of such an institution priority
over the claims of general unsecured creditors of such an institution in the
event of a liquidation or other resolution of such institution.
 
     The BHC Act currently permits adequately capitalized and adequately managed
bank holding companies from any state to acquire banks and bank holding
companies located in any other state, subject to certain conditions. Effective
June 1, 1997, the Corporation's bank subsidiaries have the ability, subject to
certain restrictions, to consolidate with other banking subsidiaries of the
Corporation or to acquire by acquisition or merger branches outside of their
home state. The Corporation has taken advantage of such and certain related
state actions as evidenced by the September 6, 1996 merger of PNC Bank, National
Association and Midlantic Bank, National Association, and may do so again in the
future with its bank subsidiaries. Competition may increase as banks branch
across state lines and enter new markets.

                CONSOLIDATED RATIO OF EARNINGS TO FIXED CHARGES
 
     The following unaudited table presents the consolidated ratio of earnings
to fixed charges of PNC. The consolidated ratio of earnings to fixed charges has
been computed by dividing income before income taxes and cumulative effect of
changes in accounting principles and fixed charges by fixed charges. Fixed
charges represent all interest expense (ratios are presented both excluding and
including interest on deposits), the portion of net rental expense which is
deemed to be equivalent to interest on debt, borrowed funds discount
amortization expense and distributions on trust preferred capital securities.
Interest expense (other than on deposits) includes interest on bank notes and
senior debt, federal funds purchased, repurchase agreements, other borrowed
funds and subordinated debt. Since PNC Funding is a provider of funds to PNC and
its subsidiaries, fixed charges ratios have been presented on a consolidated
basis.

                                USE OF PROCEEDS
 
     Unless otherwise provided in the Prospectus Supplement, PNC Funding and PNC
will apply the net proceeds from the sale of the Securities offered hereby to
their general funds to be used for corporate financing purposes, including
advances to PNC (in the case of PNC Funding) and subsidiaries of PNC (including
its bank subsidiaries), financing of possible future acquisitions, repayment of
outstanding indebtedness and repurchases of issued and outstanding shares of
Common Stock under authorized programs of PNC. The amount and timing of advances
will depend on future growth and financing requirements of PNC and its
subsidiaries. Pending ultimate application, the net proceeds may be used to make
short-term investments or reduce borrowed funds. In view of anticipated funding
requirements, PNC Funding or PNC may from time to time engage in additional
financings of a character and in amounts to be determined.
 
                 DESCRIPTION OF DEBT SECURITIES AND GUARANTEES
 
     The Debt Securities will constitute either Senior Debt Securities of PNC
Funding or Subordinated Debt Securities of PNC Funding. The following
description of the terms of the Debt Securities sets forth certain general terms
and provisions of the Debt Securities to which any Prospectus Supplement may
relate. The particular terms of the Debt Securities and Guarantees offered by
any Prospectus Supplement ("Offered Debt Securities") and the extent, if any, to
which such general provisions may apply to the Debt Securities and Guarantees so
offered will be described in the Prospectus Supplement relating to such Offered
Debt Securities.
 
     The Offered Debt Securities are to be issued under an Indenture, dated as
of December 1, 1991, as amended by a Supplemental Indenture dated as of February
15, 1993 (as amended, the "Indenture"), a copy of which has been filed with the
Commission. The Chase Manhattan Bank, formerly known as Chemical Bank and as
successor by merger to Manufacturers Hanover Trust Company, shall be the Trustee
under the Indenture ("Trustee"), unless a different Trustee for a series of Debt
Securities is named in the Prospectus Supplement. For each series of Debt
Securities, a supplemental indenture may be entered into among PNC Funding, PNC
and The Chase Manhattan Bank or such other Trustee as may be named in the
Prospectus Supplement relating to such series of Debt Securities. 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 defined terms shall be incorporated herein
by reference.
 
GENERAL
 
     The Debt Securities will be unsecured obligations of PNC Funding.
 
     Although the amount of Offered Debt Securities will be limited to the
amount that will result in net proceeds to PNC Funding as described on the cover
page of this Prospectus, the Indenture does not limit the aggregate principal
amount of debt securities that may be issued thereunder from time to time in one
or more series.
 
     Reference is made to the Prospectus Supplement relating to the particular
series of Debt Securities offered thereby for the terms of the Offered Debt
Securities, including, where applicable; (1) the form, title and denomination of
the Debt Securities; (2) the aggregate principal amount of the Debt Securities;
(3) the date or dates on which Debt Securities may be issued; (4) the date or
dates on which the principal of, and premium, if any, on the Debt Securities
shall be payable; (5) the rate or rates, or the method of determination thereof,
at which the Debt Securities shall bear interest, if any, the date or dates from
which such interest shall accrue, and the Interest Payment Dates on which such
interest shall be payable; (6) the priority of payment of such Debt Securities
and thus whether they shall be designated as Senior Debt Securities or
Subordinated Debt Securities; (7) the place or places where the principal of,
and premium, if any, and interest on Debt Securities of the series shall be
payable; (8) the provisions, if any, for optional or mandatory redemption of the
Debt Securities, including any sinking fund provisions; (9) if other than the
principal amount thereof, the
 
                                        7
<PAGE>   9
 
portion of the principal amount of Debt Securities which shall be payable upon
declaration of acceleration of the Maturity thereof in accordance with the
provisions of the Indenture; (10) whether payment of the principal of, premium,
if any, and interest, if any, on the Debt Securities shall be with or without
deduction for taxes, assessments or governmental charges, and with or without
reimbursement of taxes, assessments or governmental charges paid by Holders;
(11) any Events of Default or Defaults with respect to the Debt Securities that
differ from those set forth in the Indenture; (12) whether the securities of
such series are to be issued in a form registered as to principal ("Registered
Securities") (with or without interest coupons ("Coupons")) or in a form
registered with regard to principal and interest ("Fully Registered Securities")
or in bearer form ("Unregistered Securities"), or as both Registered Securities
and Unregistered Securities; (13) the currency or currencies, or currency unit
or currency units in which the principal of, and premium, if any, and interest,
if any, on the Debt Securities are to be denominated, payable, redeemable or
repurchaseable, as the case may be; (14) if other than as set forth in the
Indenture, provisions the satisfaction and discharge of the indebtedness
represented by the Debt Securities; (15) whether the Debt Securities of such
series are issuable as a global security and, in such case, the identity of the
depositary for such series; (16) any trustees, paying agents, transfer agents or
registrars for the Debt Securities; (17) with regard to Debt Securities that do
not bear interest, the dates for certain required reports to the Trustee; (18)
any special federal income tax considerations applicable to any Offered Debt
Securities; and (19) any other terms of such Debt Securities.
 
     Any Subordinated Debt Securities offered are intended to be included as
regulatory capital under recent interpretations of the Federal Reserve Board
and, as a result, contain subordination and acceleration provisions different
from, and covenants more limited than in, prior issuances of PNC Funding's
Subordinated Securities.
 
     If any of the Debt Securities are sold for foreign currencies or foreign
currency units or if the principal of or any interest on any series of Debt
Securities is payable in foreign currencies or foreign currency units, the
restrictions, elections, tax consequences, specific terms and other information
with respect to such issue of Debt Securities and such currencies or currency
units will be set forth in the Prospectus Supplement relating thereto.
 
     Although the Indenture provides that Debt Securities may be issued as
Registered Securities, with or without Coupons, or Unregistered Securities, each
series of Debt Securities will be issued as Fully Registered Securities unless
the Prospectus Supplement provides otherwise. Debt Securities that are not
registered as to interest shall have Coupons attached, unless issued as Original
Issue Discount Securities. All references to the Debt Securities shall, where
applicable, include the Coupons, if any, appertaining thereto.
 
     Principal of, and premium, if any, and interest on Fully Registered
Securities will be payable at the Place of Payment designated for such Debt
Securities; provided that payment of interest may, at the option of PNC Funding,
be made by check mailed to the address of the person entitled thereto as it
appears in the Security Register at the close of business on the day or days
specified in the Prospectus Supplement relating to such Debt Securities. The
principal of, and premium, if any, and interest on any Debt Securities in other
forms will be payable in such manner and at such place or places as may be
designated by PNC Funding and specified in the Prospectus Supplement relating to
such Debt Securities. (Sections 3.01 and 5.01)
 
     The Debt Securities may be exchanged, and Registered Securities may be
transferred, at the Corporate Trust Office of the Trustee for such series of
Debt Securities or at any other office or agency maintained by PNC Funding or
PNC for such purposes. Unregistered Securities and Coupons shall be transferred
by delivery. No service charge will be made for any transfer or exchange of the
Debt Securities, but PNC Funding may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.
(Section 3.05)
 
     Unless the Prospectus Supplement provides otherwise, each series of the
Debt Securities will be issued only in denominations of $1,000 or any integral
multiple thereof and payable in Dollars. (Section 3.02) Under the Indenture,
however, Debt Securities may be issued in any denomination and payable in a
foreign currency or currency unit. (Section 3.01)
 
                                        8
<PAGE>   10
 
     Debt Securities may be issued with "original issue discount" (within the
meaning of the Internal Revenue Code). Federal income tax consequences and other
special considerations applicable to any such securities issued with original
issue discount will be described in the Prospectus Supplement relating thereto.
 
SENIOR DEBT SECURITIES
 
     The Senior Debt Securities will rank equally with all Senior Indebtedness
of PNC Funding. At June 30, 1997, such outstanding Senior Indebtedness of PNC
Funding was approximately $513.7 million.
 
     Senior Indebtedness of PNC Funding, defined in the Indenture as "Senior
Company Indebtedness," means the principal of, and premium, if any, and interest
on (i) all indebtedness for money borrowed, whether outstanding on the date of
execution of the Indenture or thereafter created, assumed or incurred, except
(A) such indebtedness as is by its terms expressly stated not to be superior in
right of payment to the Subordinated Debt Securities or to rank pari passu with
the Subordinated Debt Securities, and (B) PNC Funding's 9 7/8% Subordinated
Notes Due 2001, 6 7/8% Subordinated Notes Due 2003, 6 1/8% Subordinated Notes
Due 2003, 7 3/4% Subordinated Notes Due 2004 and 6 7/8% Subordinated Notes Due
2007 and CCNB Corporation's 10.55% Equity Commitment Notes Due 1998 assumed by
PNC Funding and PNC in connection with the acquisition of CCNB Corporation on
October 23, 1992 and (ii) any deferrals, renewals or extensions of any such
Senior Indebtedness of PNC Funding. The term "indebtedness for money borrowed"
as used in the prior sentence means any obligation of, or any obligation
guaranteed by, PNC Funding for the repayment of money borrowed, whether or not
evidenced by bonds, debentures, notes or other written instruments, any
capitalized lease obligation and any deferred obligation for payment of the
purchase price of any property or assets. Senior Indebtedness of PNC Funding
would include any borrowings under the $500 million credit facility under an
Amended and Restated Credit Agreement dated as of March 18, 1996 (the "$500
Million Credit Facility"), under which no amounts are outstanding as of the date
of this Prospectus. There is no limitation under the Indenture on the issuance
of additional Senior Indebtedness of PNC Funding.
 
SUBORDINATED DEBT SECURITIES
 
     The payment of the principal of and interest on the Subordinated Debt
Securities will, to the extent set forth in the Indenture, be subordinated in
right of payment to the prior payment in full of all Senior Indebtedness of PNC
Funding. (Section 12.01) In certain events of insolvency, the payment of the
principal of and interest on the Subordinated Debt Securities will, to the
extent set forth in the Indenture, also be effectively subordinated in right of
payment to the prior payment in full of all Other Company Obligations (as
defined in the Indenture). (Section 12.13) Other Company Obligations means
obligations of PNC Funding associated with derivative products such as interest
rate and currency exchange contracts, foreign exchange contracts, commodity
contracts or any similar arrangements, unless the instrument by which PNC
Funding incurred, assumed or guaranteed the obligation expressly provides that
it is subordinate or junior in right of payment to any other indebtedness or
obligations of PNC Funding. At June 30, 1997, there were no Other Company
Obligations of PNC Funding. (Section 1.01)
 
     Upon any payment or distribution of assets to creditors upon any
liquidation, dissolution, winding up, reorganization, assignment for the benefit
of creditors, marshaling of assets or any bankruptcy, insolvency or similar
proceedings of PNC Funding, the holders of all Senior Indebtedness of PNC
Funding will first be entitled to receive payment in full of all amounts due or
to become due thereon before the Holders of the Subordinated Debt Securities
will be entitled to receive any payment in respect of the principal of or
interest on the Subordinated Debt Securities. If upon any such payment or
distribution of assets to creditors there remain, after giving effect to such
subordination provisions in favor of the holders of Senior Indebtedness of PNC
Funding, any amounts of cash, property or securities available for payment or
distribution in respect of Subordinated Debt Securities (as defined in the
Indenture, "Excess Proceeds"), and if, at such time, any creditors in respect of
Other Company Obligations have not received payment in full of all amounts due
or to become due on or in respect of such Other Company Obligations, then such
Excess Proceeds shall first be applied to pay or provide for the payment in full
of such Other Company Obligations before any payment or distribution may be made
in respect of the Subordinated Debt Securities. In addition, no payment may be
 
                                        9
<PAGE>   11
 
made of the principal of or interest on the Subordinated Debt Securities, or in
respect of any retirement, purchase or other acquisition of any of the
Subordinated Debt Securities at any time when (i) there is a default in the
payment of the principal of, or premium, if any, or interest on or otherwise in
respect of any Senior Indebtedness of PNC Funding or (ii) any event of default
with respect to any Senior Indebtedness of PNC Funding has occurred and is
continuing, or would occur as a result of such payment on the Subordinated Debt
Securities or any retirement, purchase or other acquisition of any of the
Subordinated Debt Securities permitting the holders of such Senior Indebtedness
of PNC Funding to accelerate the maturity thereof. Except as described above,
the obligation of PNC Funding to make payment of the principal of or interest on
the Subordinated Debt Securities will not be affected. By reason of such
subordination, in the event of insolvency, holders of the Subordinated Debt
Securities may recover less, ratably, than holders of Senior Indebtedness of PNC
Funding and Other Company Obligations and may also recover less, ratably, than
holders of Existing Company Subordinated Indebtedness and other creditors of PNC
Funding. (Sections 12.01, 12.02, 12.03, and 12.13)
 
     Existing Company Subordinated Indebtedness means PNC Funding's 9 7/8%
Subordinated Notes Due 2001 and CCNB Corporation's 10.55% Equity Commitment
Notes Due 1998 assumed by PNC Funding and PNC in connection with the acquisition
of CCNB Corporation on October 23, 1992. (Section 1.01) At June 30, 1997, the
Existing Company Subordinated Indebtedness was approximately $101.3 million.
 
     PNC Funding's obligations under the Subordinated Debt Securities shall rank
pari passu in right of payment with each other and with the Existing Company
Subordinated Indebtedness, subject to the obligations of the Holders of
Subordinated Debt Securities to pay over any Excess Proceeds to creditors in
respect of Other Company Obligations as provided in the Indenture. (Section
12.13)
 
GUARANTEES
 
     PNC will unconditionally guarantee the due and punctual payment of the
principal of, premium, if any, and interest on the Debt Securities when and as
the same shall become due and payable, whether at maturity, upon redemption or
otherwise. (Section 3.12)
 
GUARANTEES OF SENIOR DEBT SECURITIES
 
     The Guarantees of Senior Debt Securities will rank equally with all Senior
Indebtedness of PNC. At June 30, 1997, the outstanding Senior Indebtedness of
PNC was approximately $869.9 million, which is inclusive of the guarantee of
Senior Indebtedness of PNC Funding.
 
     Senior Indebtedness of PNC, defined in the Indenture as "Senior Guarantor
Indebtedness," means the principal of, and premium, if any, and interest on (i)
all indebtedness of PNC for money borrowed, whether outstanding on the date of
execution of the Indenture or thereafter created, assumed or incurred, except
(A) such indebtedness as is by its terms expressly stated not to be superior in
right of payment to the Subordinated Guarantees or to rank pari passu with the
Subordinated Guarantees, (B) PNC's 8 1/4% Convertible Subordinated Debentures
Due 2008 and PNC's 8 1/2% Convertible Subordinated Debentures Due 2005
originally issued by Citizens Fidelity Corporation, and (C) PNC's Guarantee of
PNC Funding's 9 7/8% Subordinated Notes Due 2001, 6 7/8% Subordinated Notes Due
2003, 6 1/8% Subordinated Notes Due 2003, 7 3/4% Subordinated Notes Due 2004 and
6 7/8% Subordinated Notes Due 2007 and CCNB Corporation's 10.55% Equity
Commitment Notes Due 1998 assumed by PNC Funding and PNC in connection with the
acquisition of CCNB Corporation on October 23, 1992, and (ii) any deferrals,
renewals or extensions of any such Senior Indebtedness of PNC. The term
"indebtedness for money borrowed" as used in the prior sentence means any
obligation of, or any obligation guaranteed by, PNC for the repayment of money
borrowed, whether or not evidenced by bonds, debentures, notes or other written
instruments, any capitalized lease obligation and any deferred obligation for
payment of the purchase price of any property or assets. Senior Indebtedness of
PNC includes PNC's Guarantee of PNC Funding's 4.93% Senior Notes Due 1998, 5.43%
Senior Notes Due 2000 and 5.18% Senior Notes Due 1999 and the following joint
and several obligations of PNC and PNC Bancorp, Inc. assumed in connection with
the merger of Midlantic Corporation with PNC Bancorp, Inc. at December 31, 1996:
8 1/4% Convertible Subordinated Debentures Due 2010, 9.875% Subordinated Capital
 
                                       10
<PAGE>   12
 
Notes Due 1999, 9.20% Subordinated Capital Notes Due 2001 and 9.25% Senior Notes
Due 1999. Senior Indebtedness of PNC would also include PNC's Guarantee of any
borrowings under the $500 Million Credit Facility. There is no limitation under
the Indenture on the issuance of additional Senior Indebtedness of PNC.
 
GUARANTEES OF SUBORDINATED DEBT SECURITIES
 
     The payment of the principal of and interest on the Subordinated Debt
Securities pursuant to the Guarantees of the Subordinated Debt Securities
("Subordinated Guarantees") will, to the extent set forth in the Indenture, be
subordinated in right of payment to the prior payment in full of all Senior
Indebtedness of PNC. (Section 12.04) In certain events of insolvency, the
payment of the principal of and interest on the Subordinated Guarantees will, to
the extent set forth in the Indenture, also be effectively subordinated in right
of payment to the prior payment in full of all Other Guarantor Obligations (as
defined in the Indenture). (Section 12.05) Other Guarantor Obligations means
obligations of PNC associated with derivative products such as interest rate and
currency exchange contracts, foreign exchange contracts, commodity contracts or
any similar arrangements, unless the instrument by which PNC incurred, assumed
or guaranteed the obligation expressly provides that it is subordinate or junior
in right of payment to any other indebtedness or obligations of PNC. (Section
1.01) At June 30, 1997, there were no Other Guarantor Obligations of PNC.
 
     Upon any payment or distribution of assets to creditors upon any
liquidation, dissolution, winding up, reorganization, assignment for the benefit
of creditors, marshalling of assets or any bankruptcy, insolvency or similar
proceedings of PNC, the holders of all Senior Indebtedness of PNC will first be
entitled to receive payment in full of all amounts due or to become due thereon
before the Holders of the Subordinated Guarantees will be entitled to receive
any payment in respect of the principal of or interest on the Subordinated Debt
Securities pursuant to the Subordinated Guarantees. If upon any such payment or
distribution of assets to creditors there remain, after giving effect to such
subordination provisions in favor of the holders of Senior Indebtedness of PNC,
any amounts of cash, property or securities available for payment or
distribution in respect of Subordinated Guarantees (as defined in the Indenture,
"Excess Proceeds"), and if, at such time, any creditors in respect of Other
Guarantor Obligations have not received payment in full of all amounts due or to
become due on or in respect of such Other Guarantor Obligations, then such
Excess Proceeds shall first be applied to pay or provide for the payment in full
of such Other Guarantor Obligations before any payment or distribution may be
made in respect of the Subordinated Guarantees. In addition, no payment may be
made of the principal of or interest on the Subordinated Debt Securities
pursuant to the Subordinated Guarantees or in respect of any retirement,
purchase or other acquisition of any of the Subordinated Debt Securities
pursuant to the Subordinated Guarantees, at any time when (i) there is a default
in the payment of the principal of, premium, if any, or interest on or otherwise
in respect of any Senior Indebtedness of PNC or (ii) any event of default with
respect to any Senior Indebtedness of PNC has occurred and is continuing, or
would occur as a result of such payment on the Subordinated Debt Securities
pursuant to the Subordinated Guarantees or any retirement, purchase or other
acquisition of any of the Subordinated Debt Securities pursuant to the
Subordinated Guarantees, permitting the holders of such Senior Indebtedness of
PNC to accelerate the maturity thereof. Except as described above, the
obligation of PNC to make payment under the Subordinated Guarantees will not be
affected. By reason of such subordination, in the event of insolvency, holders
of Subordinated Guarantees of PNC may recover less, ratably, than holders of
Senior Indebtedness of PNC and Other Guarantor Obligations and may also recover
less, ratably, than holders of Existing Guarantor Subordinated Indebtedness (as
defined in the Indenture) and other creditors of PNC. (Section 3.12, 12.04,
12.05, 12.06 and 12.14)
 
     Existing Guarantor Subordinated Indebtedness means the Guarantor's 8 1/4%
Convertible Subordinated Debentures Due 2008, PNC's Convertible Subordinated
Debentures Due 2005 originally issued by Citizens Fidelity Corporation, PNC's
Guarantee of PNC Funding's 9 7/8% Subordinated Notes Due 2001, and CCNB
Corporation's 10.55% Equity Commitment Notes Due 1998 assumed by PNC Funding and
PNC in connection with the acquisition of CCNB on October 23, 1992. (Section
1.01) At June 30, 1997, the Existing Guarantor Subordinated Indebtedness was
approximately $102.1 million. PNC's 8.315% Junior Subordinated Debentures Due
2027, in the aggregate principal amount of $300 million, issued on May 12, 1997
would be subordinated to the Debt Securities and the Existing Guarantor
Subordinated Indebtedness.
 
                                       11
<PAGE>   13
 
     PNC's obligations under the Subordinated Guarantees shall rank pari passu
in right of payment with each other and with the Existing Guarantor Subordinated
Indebtedness, subject to the obligations of the Holders of Subordinated
Guarantees to pay over any Excess Proceeds to creditors in respect of Other
Guarantor Obligations as provided in the Indenture. (Section 12.14)
 
     Since PNC is a holding company separate from its subsidiaries, the rights
of PNC to share in the distribution of the assets of any subsidiary upon the
subsidiary's liquidation, reorganization or otherwise will be subject to the
prior claims of the subsidiary's creditors (including in the case of any bank
subsidiary, its depositors), except to the extent that PNC may itself be a
creditor with recognized claims against the subsidiary. In addition, there are
certain regulatory and other limitations on the payment of dividends and on
loans and other transfers of funds to PNC by its bank subsidiaries. See
"Supervision, Regulation and Other Matters."
 
CERTAIN COVENANTS
 
     The Indenture contains certain covenants that impose various restrictions
on PNC Funding and PNC and, as a result, afford the holders of Debt Securities
certain protections. Although statements have been included as to the general
purpose and effect of the covenants, investors must review the full text of the
covenants to be able to meaningfully evaluate the covenants.
 
Restriction on Sale or Issuance of Voting Stock of a Principal Subsidiary Bank
 
     The covenant described below is designed to ensure that, for so long as any
Senior Debt Securities are issued and outstanding, PNC will continue directly or
indirectly to own and thus serve as the holding company for its Principal
Subsidiary Banks (defined as each of (i) PNC Bank, (ii) any other Subsidiary
Bank the consolidated assets of which constitute 20% or more of the consolidated
assets of PNC and its subsidiaries, (iii) any other Subsidiary Bank designated
as a Principal Subsidiary Bank by the board of directors of PNC, or (iv) any
Subsidiary that owns any Voting Shares or certain rights to acquire Voting
Shares of any Principal Subsidiary Bank, and their respective successors,
provided any such successor is a Subsidiary Bank or a Subsidiary, as
appropriate). Principal Subsidiary Banks, in the past, have provided PNC income
in the form of dividends. See "Supervision, Regulation and Other Matters." The
Indenture prohibits PNC, unless debtholder consent is obtained from the holders
of Senior Debt Securities, from (i) selling or otherwise disposing of, and
permitting a Principal Subsidiary Bank to issue, Voting Shares or certain rights
to acquire Voting Shares of a Principal Subsidiary Bank, (ii) permitting the
merger or consolidation of a Principal Subsidiary Bank with or into any other
corporation, or (iii) permitting the sale or other disposition of all or
substantially all the assets of any Principal Subsidiary Bank, if after giving
effect to any one of such transactions and the issuance of the maximum number of
Voting Shares issuable upon the exercise of all such rights to acquire Voting
Shares of a Principal Subsidiary Bank, PNC would own directly or indirectly less
than 80% of the Voting Shares of such Principal Subsidiary Bank, with the
following exceptions: (i) transactions required by any law, or any regulation or
order of any governmental authority; (ii) transactions required as a condition
imposed by any governmental authority to the acquisition by PNC, directly or
indirectly, or any other corporation or entity if thereafter, (a) PNC would own
at least 80% of the Voting Shares of such other corporation or entity, (b) the
Consolidated Banking Assets of PNC would be at least equal to those prior
thereto, and (c) the board of directors of PNC shall have designated such other
corporation or entity a Principal Subsidiary Bank; (iii) transactions that do
not reduce the percentage of Voting Shares of such Principal Subsidiary Bank
owned directly or indirectly by PNC; and (iv) transactions where the proceeds
are invested within 180 days after such transaction in any one or more
Subsidiary Banks. However, the Indenture permits the merger of a Principal
Subsidiary Bank with and into a Principal Subsidiary Bank or PNC, the
consolidation of Principal Subsidiary Banks into a Principal Subsidiary Bank or
PNC, or the sale or other disposition of all or substantially all of the assets
of any Principal Subsidiary Bank to another Principal Subsidiary Bank or PNC,
if, in any such case in which the surviving, resulting or acquiring entity is
not PNC, PNC would own, directly or indirectly, at least 80% of the Voting
Shares of the Principal Subsidiary Bank surviving such merger, resulting from
such consolidation or acquiring such assets. (Section 5.06)
 
                                       12
<PAGE>   14
 
Ownership of PNC Funding
 
     The Indenture contains a covenant that, so long as any of the Debt
Securities are outstanding and subject to certain rights described below under
"Consolidation or Merger," PNC will continue to own, directly or indirectly, all
of the outstanding voting shares of PNC Funding. (Section 5.07)
 
Restriction on Liens
 
     The purpose of the restriction on liens covenant is to preserve PNC's
direct or indirect interest in Voting Shares of Principal Subsidiary Banks free
of security interests of other creditors. The covenant permits certain specified
liens and liens where the Senior Debt Securities are equally secured. The
Indenture prohibits PNC and its subsidiaries from creating or permitting any
liens (other than certain tax and judgment liens) upon Voting Shares of any
Principal Subsidiary Bank to secure indebtedness for borrowed money without
making effective provision whereby the Senior Debt Securities shall be equally
and ratably secured, except that PNC may create or permit (i) purchase money
liens and liens on Voting Shares of any Principal Subsidiary Bank existing at
the time such Voting Shares are acquired or created within 120 days thereafter;
(ii) the acquisition of any Voting Shares of any Principal Subsidiary Bank
subject to liens at the time of acquisition or the assumption of obligations
secured by a lien on such Voting Shares; (iii) under certain circumstances,
renewals, extensions or refunding of the liens described in (i) and (ii) above;
and (iv) liens to secure loans or other extensions of credit under Section 23A
of the Federal Reserve Act or any successor or similar federal law or
regulation. (Section 5.08)
 
Consolidation or Merger
 
     The covenant described below protects the holders of Debt Securities upon
certain transactions involving PNC Funding or PNC by requiring any successor to
PNC Funding or PNC to assume the predecessor's obligations under the Indenture,
and prohibits transactions that would result in an Event of Default, a Default
or an event which could become an Event of Default or Default under the
Indenture. PNC Funding or PNC may consolidate with, merge into, or transfer
substantially all of its properties to, any other corporation organized under
the laws of any domestic jurisdiction, provided that the successor corporation
assumes all obligations of PNC Funding or PNC, as the case may be, under the
Debt Securities and the Guarantees and under the Indenture, that after giving
effect to the transaction no Event of Default or Default, and no event which,
after notice or lapse of time, would become an Event of Default or Default,
shall have occurred and be continuing, and that certain other conditions are
met. (Sections 10.01 and 10.03)
 
     Except as may be disclosed in a Prospectus Supplement and other than the
restrictions on liens on Voting Shares of Principal Subsidiary Banks and on
certain dispositions of Principal Subsidiary Banks described above, the
Indenture and the Debt Securities do not contain any covenants or other
provisions designed to afford holders of the Debt Securities protection in the
event of a highly leveraged transaction involving PNC.
 
MODIFICATION AND WAIVER
 
     Modifications of the Indenture may be made by PNC Funding, PNC and the
Trustee with the consent of the Holders of the majority in aggregate principal
amount of Outstanding Debt Securities of each series affected thereby; provided,
however, that no such modification may, without the consent of the Holder of
each Outstanding Debt Security affected thereby: (i) change the Maturity of the
principal of, or the stated Maturity of any installment of interest on, any such
Debt Security; (ii) reduce the principal amount of, or the premium, if any, or
the interest on such Debt Security (including, in the case of an Original Issue
Discount Security, the amount payable upon acceleration of the maturity
thereof); (iii) change the place or currency of payment of principal of or
premium, if any, or interest on any such Debt Security; (iv) impair the right to
institute suit for the enforcement of any payment on or with respect to any such
Debt Security; (v) reduce the aforesaid percentage in principal amount of
Outstanding Debt Securities of any series necessary to modify the Indenture or
the percentage in principal amount of Outstanding Debt Securities necessary for
any waiver of compliance with conditions and defaults thereunder; or (vi) modify
or affect in any manner adverse to a Holder the terms and conditions of the
Guarantees. (Section 9.02)
 
                                       13
<PAGE>   15
 
     Modification and amendment of the Indenture may be made by PNC Funding,
PNC, and the Trustee without the consent of any Holder of Debt Securities for
any of the following purposes: (i) to evidence the succession of another
corporation to PNC Funding or PNC; (ii) to provide for the acceptance of
appointment of a successor Trustee; (iii) to add to the covenants of PNC Funding
or PNC for the benefit of the Holders of Debt Securities; (iv) to cure any
ambiguity, defect or inconsistency in the Indenture, provided such action does
not adversely affect the Holders of Debt Securities in any material respect; (v)
to secure the Debt Securities under applicable provisions of the Indenture; (vi)
to establish the form or terms of Debt Securities; (vii) to permit the payment
in the United States of principal, premium or interest on Unregistered
Securities; or (viii) to provide for the issuance of uncertificated Debt
Securities in place of certificated Debt Securities. (Section 9.01)
 
     The Holders of a majority in principal amount of Outstanding Debt
Securities of any series may waive, insofar as that series is concerned,
compliance with certain covenants, including those described under the captions
above entitled "Restriction on Sale or Issuance of Capital Stock of a Principal
Subsidiary Bank," "Ownership of PNC Funding" and "Restriction on Liens."
(Section 5.09) No waiver by the Holders of any series of Subordinated Debt
Securities is required with respect to the covenant described under the caption
above entitled "Restriction on Sale or Issuance of Voting Stock of a Principal
Subsidiary Bank." (Section 5.10) Covenants concerning the payment of principal,
premium, if any, and interest on the Debt Securities, compliance with the terms
of the Indenture, maintenance of an agency and certain monies held in trust, may
only be waived pursuant to a supplemental indenture executed with the consent of
each Holder of Debt Securities affected by such waiver. The covenant concerning
certain reports required by federal law may not be waived.
 
EVENTS OF DEFAULT, DEFAULTS, WAIVERS
 
     The Indenture defines an Event of Default with respect to any series of
Senior Debt Securities as being any one of the following events and such other
event as may be established for the Debt Securities of a particular series: (i)
default for 30 days in the payment of interest on such series; (ii) default in
any payment of principal of or premium, if any, on such series; (iii) default in
the payment of any sinking fund installment with respect to such series; (iv)
default for 90 days after appropriate notice in performance of any other
covenant or warranty in the Indenture (other than a covenant or warranty
included in the Indenture solely for the benefit of a series of Debt Securities
other than that series); (v) the occurrence of certain events relating to
bankruptcy, insolvency or reorganization of PNC, PNC Funding or any Principal
Subsidiary Bank; or (vi) any other Event of Default provided in the supplemental
indenture under which such Senior Debt Securities are issued. (Section 7.01(a))
 
     The Indenture defines an Event of Default with respect to any series of
Subordinated Debt Securities as certain events involving the bankruptcy or
reorganization of PNC or any Principal Subsidiary Bank. There is no right of
acceleration in the case of events involving the bankruptcy, insolvency or
reorganization of PNC Funding or of a default in the payment of principal,
interest, premium, if any, or any sinking fund payment with respect to a series
of Subordinated Debt Securities or in the case of a default in the performance
of any other covenant of PNC Funding or PNC in the Indenture. The Indenture
defines a Default with respect to any series of Subordinated Debt Securities as
any of the items listed in (i) through (iv) of the above paragraph, events
involving the bankruptcy, insolvency or reorganization of PNC Funding and such
other Default as may be established for the Subordinated Debt Securities of a
particular series. A breach of the covenant described under the caption above
entitled "Restriction on Sale or Issuance of Voting Stock of a Principal
Subsidiary Bank" will not result in a default with respect to any Series of
Subordinated Debt Securities. (Sections 7.01(b) and (c))
 
     In case an Event of Default shall occur and be continuing with respect to
any series of Debt Securities, either the Trustee or the Holders of not less
than 25% in principal amount of Outstanding Debt Securities of that series may
declare the principal of such series (or if Debt Securities of that series are
Original Issue Discount Securities, such portion of the principal as may be
specified in the terms of that series) to be due and payable immediately. At any
time after a declaration of acceleration has been made but before a judgment or
decree for payment of money due has been obtained by the Trustee, the Holders of
a majority in principal
 
                                       14
<PAGE>   16
 
amount of the Outstanding Debt Securities of such series may rescind any
declaration of acceleration and its consequences, if all payments due (other
than those due as a result of acceleration) have been made and all Events of
Default and Defaults have been remedied or waived. Any Event of Default or
Default with respect to a particular series of Debt Securities may be waived by
the Holders of a majority in principal amount of the Outstanding Debt Securities
of such series, except in each case of a failure to pay principal of, or
premium, if any, or interest on, or any sinking fund installment in respect of,
such Debt Securities or in respect of a covenant or provision of the Indenture
which cannot be modified without the consent of the Holder of each Outstanding
Debt Security affected. (Sections 7.02, 7.08 and 7.13)
 
     Subject to the provisions of the Indenture relating to the duties of the
Trustee in case an Event of Default or a Default shall occur and be continuing,
the Trustee will be under no obligation to exercise any of the rights or powers
in the Indenture at the request or direction of Holders of Debt Securities,
unless such Holders shall have offered to the Trustee reasonable security or
indemnity. Subject to such provisions for indemnification and certain
limitations contained in the Indenture, the Holders of a majority in principal
amount of the Outstanding Debt 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 with respect to Debt Securities of such series.
(Sections 8.03 and 7.12)
 
     The Indenture provides that in the event of a default of 30 days in the
payment of interest upon any Debt Security of any series, or defaults in the
payment of any principal of or premium, if any, or any sinking fund installment
with respect to any Debt Securities of any series, PNC Funding will, upon demand
of the Trustee, pay to it, for the benefit of the Holder of any such Debt
Security the whole amount then due and payable on such Debt Security for
principal and interest. The Indenture, as amended, further provides that if PNC
Funding fails to pay such amount forthwith upon such demand, the Trustee may,
among other things, institute a judicial proceeding for the collection thereof.
(Section 7.03)
 
     The Indenture requires PNC Funding and PNC to file with the Trustee, on an
annual basis, certificates as to the absence of any default and as to compliance
with the terms of the Indenture. The Indenture provides that the Trustee may
withhold notice to the Holders of Debt Securities of any default (except in
payment of principal, premium, if any, interest or sinking fund installment) if
the Trustee considers it in the interest of the Holders of Debt Securities to do
so. (Sections 5.04 and 8.02)
 
     No Holder of any Debt Security of any series 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 Event of Default or Default with respect to Debt
Securities of that series and unless the Holders of at least 25% in principal
amount of the Outstanding Debt Securities of that series 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 principal amount of the Outstanding Debt Securities of that
series a direction inconsistent with such request and shall have failed to
institute such proceeding within 60 days. However, the Holder of any Debt
Security will have an absolute right to receive payment of the principal of, and
premium, if any, and interest on such Debt Security on the due dates expressed
in such Debt Security and to institute suit for the enforcement of any such
payment. (Sections 7.07 and 7.08)
 
DEFEASANCE
 
     Except as may otherwise be provided in the applicable Prospectus Supplement
with respect to the Debt Securities of any series, the Indenture provides that
PNC Funding and PNC shall be discharged from their obligations under the Debt
Securities of a series at any time prior to the Stated Maturity or redemption
thereof when (a) PNC Funding or PNC has irrevocably deposited with the Trustee,
in trust, (i) sufficient funds to pay the principal of (and premium, if any),
and interest to Stated Maturity (or redemption) on, the Debt Securities of such
series, or (ii) such amount of government securities as will, together with the
predetermined and certain income to accrue thereon without consideration of any
reinvestment thereof, be sufficient to pay when due the principal of, and
premium, if any, and interest to Stated Maturity (or redemption) on, the Debt
Securities of such series, and (b) PNC Funding or PNC has paid all other sums
payable with respect to the
 
                                       15
<PAGE>   17
 
Debt Securities of such series. Deposited funds shall be in the currency or
currency unit in which the Debt Securities are denominated. Deposited government
securities shall be direct obligations of, or obligations the principal of and
interest on which are fully guaranteed by, the government which issued the
currency in which the Debt Securities are denominated, and which are not subject
to prepayment, redemption or call. Upon such discharge, the Holders of the Debt
Securities of such series shall no longer be entitled to the benefits of the
Indenture, except for the purposes of registration of transfer and exchange of
the Debt Securities of such series, and replacement of lost, stolen or mutilated
Debt Securities, and shall look only to such deposited funds or obligations for
payment. (Sections 11.01 and 11.02)
 
     For federal income tax purposes, the deposit and discharge may, depending
on a variety of factors, result in a taxable gain or loss being recognized by
the Holders of the affected Debt Securities. Prospective investors are urged to
consult their own tax advisers as to the specific consequences of such a deposit
and discharge, including the applicability and effect of tax laws other than
federal income tax laws.
 
GLOBAL SECURITIES
 
     The Debt Securities of a series may be issued in whole or in part in the
form of a global security ("Global Security") that will be deposited with, or on
behalf, of, a depositary (the "Depositary"). Such Depositary will be The
Depository Trust Company ("DTC"), unless otherwise identified in the Prospectus
Supplement relating to such series. A Global Security may be issued as either a
Registered or Unregistered Security and in either temporary or permanent form.
Unless and until it is exchanged in whole or in part for individual certificates
evidencing Debt Securities in definitive form represented thereby, a Global
Security may not be transferred except as a whole by the Depositary for such
Global Security or any nominee thereof to a successor of such Depositary or a
nominee of such successor. (Section 2.05)
 
     If DTC is the Depositary for a series of Debt Securities, such series will
be issued as fully-registered securities registered in the name of Cede & Co.
(DTC's partnership nominee). One fully-registered Global Security will be issued
for such series of Debt Securities, in the aggregate principal amount of such
series, and will be deposited with DTC. If, however, the aggregate principal
amount of such series of Debt Securities exceeds $200 million, one Global
Security will be issued with respect to each $200 million of principal amount
and an additional Global Security will be issued with respect to any remaining
principal amount of such series.
 
     DTC is a limited-purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law, 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 Securities Exchange
Act of 1934. DTC holds securities that its participants ("Participants") deposit
with DTC. DTC also facilitates the settlement among Participants of securities
transactions, such as transfers and pledges, in deposited securities through
electronic computerized book-entry changes in Participants' accounts, thereby
eliminating the need for physical movement of securities certificates. Direct
Participants include securities brokers and dealers, banks, trust companies,
clearing corporations, and certain other organizations. DTC is owned by a number
of its Direct Participants and by the New York Stock Exchange, Inc., the
American Stock Exchange, Inc. and the National Association of Securities
Dealers, Inc. Access to the DTC system is also available to others such as
securities brokers and dealers, banks and trust companies that clear through or
maintain a custodial relationship with a Direct Participant, either directly or
indirectly ("Indirect Participants"). The rules applicable to DTC and its
Participants are on file with the Commission.
 
     Purchases of a series of Debt Securities under the DTC system will need to
be made by or through Direct Participants, which will receive a credit for the
Debt Securities on DTC's records. The ownership interest of each actual
purchaser of each Debt Security ("Beneficial Owner") is in turn to be recorded
on the Direct Participants' and Indirect Participants' records. Beneficial
Owners will not receive written confirmation from DTC of their purchase, but
Beneficial Owners are expected to receive written confirmations providing
details of the transaction, as well as provide periodic statements of their
holdings, from the Direct Participants or Indirect Participants through which
the Beneficial Owner entered into the transaction. Transfers of ownership
interests in the Debt Securities are to be accomplished by entries made on the
books of the Participants acting
 
                                       16
<PAGE>   18
 
on behalf of Beneficial Owners. Beneficial Owners will not receive certificates
representing their ownership interest in the Global Security or Global
Securities, except in the event that use of the book-entry system for such Debt
Securities is discontinued.
 
     To facilitate subsequent transfers, all Global Securities deposited by
Participants with DTC are registered in the name of DTC's partnership nominee,
Cede & Co. The deposit of Global Securities with DTC and their registration in
the name of Cede & Co. effect no change in beneficial ownership. DTC has advised
PNC and PNC Funding that DTC will have no knowledge of the actual Beneficial
Owners of the Global Securities, and that DTC's records reflect only the
identity of the Direct Participants to whose accounts Global Securities are
credited, which may or may not be the Beneficial Owners. Participants will
remain responsible for keeping account of their holdings on behalf of their
customers.
 
     Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants and by Direct
Participants and Indirect Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time.
 
     To the extent any series of Debt Securities is redeemable, redemption
notices will be sent to DTC. If less than all of the Debt Securities within an
issue are being redeemed, DTC's practice is to determine by lot the amount of
the interest of each Direct Participant in such issue to be redeemed. The
applicable Prospectus Supplement for a series of Debt Securities will indicate
whether such series is redeemable.
 
     To the extent applicable, neither DTC nor Cede & Co. will consent or vote
with respect to any Global Securities deposited with it. Under its usual
procedure, DTC will mail an Omnibus Proxy to the issuer as soon as possible
after the record date. The Omnibus Proxy assigns Cede & Co.'s consenting and
voting rights to those Direct Participants to whose accounts the Debt Securities
are credited on the record date (identified in a listing attached to the Omnibus
Proxy).
 
     Principal and interest payments on the Global Securities deposited with DTC
will be made to Cede & Co., as nominee of DTC. DTC's practice is to credit
Direct Participants' accounts, upon DTC's receipt of funds and corresponding
detail information from the issuer, on the payable date in accordance with their
respective holdings shown on DTC's records. Payments by Participants to
Beneficial Owners will be governed by standing instructions and customary
practices, as in the case with securities held for the accounts of customers
registered in "street name", and will be the responsibility of such Participant
and not DTC or PNC Funding, subject to any statutory or regulatory requirements
as may be in effect from time to time. Payment of principal and interest to Cede
& Co. will be the responsibility of the Trustee, who unless otherwise indicated
in the applicable Pricing Supplement, will be PNC Funding's paying agent,
disbursements of such payments to Direct Participants will be the responsibility
of DTC, and disbursements of such payments to Beneficial Owners will be the
responsibility of Direct Participants and Indirect Participants. None of PNC
Funding, PNC, the Trustee, any paying agent, or the registrar for the Debt
Securities will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of the Global Security or Global Securities for any series of Debt
Securities or for maintaining, supervising or reviewing any records relating to
such beneficial interests.
 
     If DTC is at any time unwilling, unable or ineligible to continue as the
Depositary and a successor depositary is not appointed by PNC Funding within 90
days, PNC Funding will issue certificated Debt Securities for each series in
definitive form in exchange for each Global Security. If PNC Funding determines
not to have a series of Debt Securities represented by a Global Security, which
it may do, it will issue certificated Debt Securities for such series in
definitive form in exchange for the Global Security. In either instance, a
Beneficial Owner will be entitled to physical delivery of certificated Debt
Securities for such series in definitive form equal in principal amount to such
Beneficial Owner's beneficial interest in the Global Security and to have such
certificated Debt Securities for such series registered in such Beneficial
Owner's name. Certificated Debt Securities so issued in definitive form will be
issued in denominations of $1,000 and integral multiples thereof and will be
issued in registered form only, without coupons.

     Any other or differing terms of the depositary arrangement will be
described in the Prospectus Supplement relating to a series of Debt Securities.
 
REGARDING THE TRUSTEE
 
     In the ordinary course of business, PNC Funding and PNC may maintain lines
of credit with one or more Trustees for a series of Debt Securities and the
Banks may maintain deposit accounts and conduct other banking transactions with
one or more Trustees for a series of Debt Securities.
 
TRUSTEE'S DUTY TO RESIGN UNDER CERTAIN CIRCUMSTANCES
 
     PNC Funding may issue both Senior and Subordinated Debt Securities under
the Indenture. Because the Subordinated Debt Securities will rank junior in
right of payment to the Senior Debt Securities, the occurrence of a default
under the Indenture with respect to the Subordinated Debt Securities or any
Senior Debt Securities could create a conflicting interest under the Trust
Indenture Act of 1939, as amended ("1939 Act"), with respect to any Trustee who
serves as trustee for both Senior and Subordinated Debt Securities. In addition,
upon the occurrence of a default under the Indenture with respect to any series
of Debt Securities the Trustee of which maintains banking relationships with PNC
Funding or PNC, such Trustee would have a conflicting interest under the 1939
Act as a result of such business relationships. If a default has not been cured
or waived within 90 days after the Trustee has or acquires a conflicting
interest, the Trustee generally is required by the 1939 Act to eliminate such
conflicting interest or resign as Trustee with respect to the Subordinated Debt
Securities or the Senior Debt Securities. In the event of the Trustee's
resignation, PNC Funding and/or PNC shall promptly appoint a successor trustee
with respect to the affected securities.
 
                          DESCRIPTION OF COMMON STOCK
 
     PNC is authorized to issue 450,000,000 shares of Common Stock. At June 30,
1997, there were 306,976,545 shares of Common Stock issued and outstanding and
40,407,600 shares held in treasury. For a description of authorized and issued
and outstanding shares of Preferred Stock of PNC, see "Description of Preferred
Stock--General."
 
     Holders of Common Stock are entitled to one vote per share on all matters
submitted to shareholders. Holders of Common Stock have neither cumulative
voting rights nor any preemptive rights for the purchase of additional shares of
any class of stock of PNC, and are not subject to liability for further calls or
assessments. The Common Stock does not have any sinking fund, conversion or
redemption provisions.
 
     Holders of Common Stock are entitled to receive such dividends as may be
declared by the Board of Directors of PNC out of funds legally available
therefor. The Board of Directors may not pay or set apart dividends on Common
Stock until dividends for all past dividend periods on any series of outstanding
preferred stock have been paid or declared and set apart for payment.
 
     In the event of dissolution or winding up of the affairs of PNC, holders of
Common Stock will be entitled to share ratably in all assets remaining after
payments to all creditors and payments required to be made in respect of
outstanding preferred stock (including accrued and unpaid dividends thereon).
 
     The Board of Directors of PNC may, except as otherwise required by
applicable law, cause the issuance of authorized shares of Common Stock without
shareholder approval to such persons and for such consideration as the Board of
Directors may determine in connection with acquisitions by PNC or for other
corporate purposes.
 
     The Chase Manhattan Bank, New York, New York, is the transfer agent and
registrar for PNC's Common Stock. The shares of Common Stock are listed on the
New York Stock Exchange under the symbol "PNC". The outstanding shares of Common
Stock are, and the shares offered hereby will be, validly issued, fully paid and
nonassessable and the holders thereof are not and will not be subject to any
liability as shareholders.

                         DESCRIPTION OF PREFERRED STOCK
 
GENERAL
 
     The Board of Directors of PNC (the "PNC Board") is authorized without
further shareholder action to cause the issuance, as of June 30, 1997, of up to
10,662,800 additional shares of Preferred Stock, and such Preferred Stock may be
issued in one or more series, each with such preferences, limitations,
designations, conversion rights, voting rights, dividend rights, voluntary and
involuntary liquidation rights and other rights as the PNC Board may determine
at the time of issuance.
 
     Under such authority, PNC has previously designated six series of preferred
stock, of which, at June 30, 1997, five series were outstanding, including:
16,048 shares of $1.80 Cumulative Convertible Preferred Stock, Series A
("Preferred Stock-A"); 4,452 shares of $1.80 Cumulative Convertible Preferred
Stock, Series B ("Preferred Stock-B"); 319,865 shares of $1.60 Cumulative
Convertible Preferred Stock, Series C ("Preferred Stock-C"); 432,310 shares of
$1.80 Cumulative Convertible Preferred Stock, Series D ("Preferred Stock-D");
and 6,000,000 shares of Fixed/Adjustable Rate Noncumulative Preferred Stock,
Series F ("Preferred Stock-F"). All shares of a former series of Preferred
Stock, designated as $2.60 Cumulative NonVoting Preferred Stock, Series E, have
been redeemed and restored to the status of authorized but unissued Preferred
Stock. See "Description of Preferred Stock--Preferred Stock Currently
Outstanding" below.
 
     The rights of the holders of PNC's Common Stock are subject to any rights
and preferences of such outstanding series of Preferred Stock, and the Preferred
Stock herein offered, and would be subject to the rights and preferences of any
additional shares of Preferred Stock, or any series thereof, which might be
issued in the future.
 
     The existence of authorized but unissued Preferred Stock could have the
effect of discouraging an attempt to acquire control of PNC. For example,
Preferred Stock could be issued to persons, firms or entities known to be
friendly to management.
 
PREFERRED STOCK OFFERED HEREIN
 
General
 
     The following description of the terms of the Preferred Stock sets forth
certain general terms and provisions of the Preferred Stock to which any
Prospectus Supplement may relate. The particular terms of any series of
Preferred Stock offered by any Prospectus Supplement and the extent, if any, to
which such general provisions may apply to the Preferred Stock so offered will
be described in the Prospectus Supplement relating to such Preferred Stock. If
so specified in the applicable Prospectus Supplement, the terms of any series of
Preferred Stock may differ from the terms set forth below. The description below
and in any Prospectus Supplement does not purport to be complete and is subject
to and qualified in its entirety by reference to the Designation of Series
relating to the Preferred Stock the form of which is incorporated by reference
as Exhibit 4.4 to the Registration Statement of which this Prospectus is a part
and the definitive form of which will be filed with the Commission.
 
     The Preferred Stock will, when issued, be fully paid and nonassessable.
Unless otherwise specified in the applicable Prospectus Supplement, the shares
of each series of Preferred Stock will upon issuance rank on a parity in all
respects with PNC's existing series of Preferred Stock, described below, and
each other then outstanding series of preferred stock of PNC. Holders of the
Preferred Stock will have no preemptive rights to subscribe for any additional
securities which may be issued by PNC. Unless otherwise specified in the
applicable Prospectus Supplement, The Chase Manhattan Bank, New York, New York,
will be the transfer agent and registrar for the Preferred Stock.
 
     Because PNC is a holding company, its rights and the rights of holders of
its securities, including the holders of Preferred Stock, to participate in the
assets of any PNC subsidiary upon the latter's liquidation or recapitalization
will be subject to the prior claims of such subsidiary's creditors and preferred
shareholders,
 
                                       19
<PAGE>   21
 
except to the extent PNC may itself be a creditor with recognized claims against
such subsidiary or a holder of preferred shares of such subsidiary. See
"Supervision, Regulation and Other Matters"
 
     PNC may, at its option, elect to offer Depositary Shares ("Depositary
Shares") evidenced by depositary receipts ("Depositary Receipts"), each
representing a fractional interest (to be specified in the Prospectus Supplement
relating to the particular series of Preferred Stock) in a share of a particular
series of the Preferred Stock issued and deposited with a Depositary (as defined
below). See "Description of Depositary Shares" below.
 
Dividends
 
     The holders of the Preferred Stock will be entitled to receive, when, as
and if declared by the Board of Directors of PNC or a duly authorized committee
thereof, out of funds legally available therefor, dividends at such rates and on
such dates as will be specified in the applicable Prospectus Supplement. Such
rates may be fixed or variable or both. If variable, the formula used for
determining the dividend rate for each dividend period will be specified in the
applicable Prospectus Supplement. Dividends will be payable to the holders of
record as they appear on the stock books of PNC on such record dates as will be
fixed by the Board of Directors of PNC or a duly authorized committee thereof.
Dividends may be paid in the form of cash, Preferred Stock (of the same or a
different series) or Common Stock of PNC, in each case as specified in the
applicable Prospectus Supplement.
 
     Dividends on any series of Preferred Stock may be cumulative or
noncumulative, as specified in the applicable Prospectus Supplement. If the
Board of Directors of PNC fails to declare a dividend payable on a dividend
payment date on any Preferred Stock for which dividends are noncumulative
("Noncumulative Preferred Stock"), then the holders of such Preferred Stock will
have no right to receive a dividend in respect of the dividend period relating
to such dividend payment date, and PNC will have no obligation to pay the
dividend accrued for such period, whether or not dividends on such Preferred
Stock are declared or paid on any future dividend payment dates.
 
     If dividends on a particular series shall have been determined to be
cumulative, no dividends shall be paid or set apart for payment or declared on
the Common Stock or on any class or series of stock of PNC ranking as to
dividends subordinate to such series (other than dividends payable in Common
Stock or in any class or series of stock of PNC ranking as to dividends and
assets subordinate to such series) and no payment shall be made or set apart for
the purchase, redemption or other acquisition for value of any shares of Common
Stock or of any class or series of stock of PNC ranking as to dividends or
assets subordinate to such series, until dividends (to the extent cumulative)
for all past dividend periods on all outstanding shares of such series have been
paid, or declared and set apart for payment, in full. In case dividends for any
dividend period are not paid in full on all shares of Preferred Stock ranking
equally as to dividends, all such shares shall participate ratably in the
payment of dividends for such period in proportion to the full amounts of
dividends to which they are respectively entitled.
 
Voting
 
     Except as provided herein or in the applicable Prospectus Supplement, or as
required by applicable law, the holders of Preferred Stock have only such voting
rights with regard to matters submitted to a vote of the shareholders of PNC as
shall be fixed and determined by PNC's Board of Directors. Except as otherwise
required by law or provided by the Board of Directors and described in the
applicable Prospectus Supplement, holders of Preferred Stock having voting
rights and holders of Common Stock vote together as one class. Holders of
Preferred Stock do not have cumulative voting rights.
 
     If PNC shall have failed to pay, or declare and set apart for payment,
dividends on all outstanding shares of Preferred Stock in an amount equal to six
quarterly dividends at the rates payable upon such shares (whether or not such
dividends are cumulative), the number of directors of PNC shall be increased by
two at the first annual meeting of the shareholders of PNC held thereafter, and
at such meeting and at each subsequent annual meeting until cumulative dividends
payable for all past dividend periods and continuous noncumulative dividends for
at least one year on all outstanding shares of Preferred Stock entitled thereto
 
                                       20
<PAGE>   22
 
shall have been paid, or declared and set apart for payment, in full, the
holders of shares of Preferred Stock of all series shall have the right, voting
as a class, to elect such two additional members of the Board of Directors to
hold office for a term of one year. Upon such payment, or such declaration and
setting apart for payment, in full, the terms of the two additional directors so
elected shall forthwith terminate, and the number of directors of PNC shall be
reduced by two, and such voting right of the holders of shares of Preferred
Stock shall cease, subject to increase in the number of directors as aforesaid
and to revesting of such voting right in the event of each and every additional
failure in the payment of dividends in an amount equal to six quarterly
dividends as aforesaid.
 
     PNC shall not, without the affirmative vote at a meeting, or the written
consent with or without a meeting, of the holders of at least two-thirds of the
then outstanding shares of Preferred Stock of all series (a) create or increase
the authorized number of shares of any class of stock ranking as to dividends or
assets prior to the Preferred Stock; or (b) change the preferences,
qualifications, privileges, limitations, restrictions or special or relative
rights granted to or imposed upon the shares of Preferred Stock in any material
respect adverse to the holders thereof, provided that if any such change will
affect any particular series materially and adversely as contrasted with the
effect thereof upon any other series, no such change may be made without, in
addition, such vote or consent of the holders of at least two-thirds of the then
outstanding shares of the particular series which would be so affected.
 
     Subject to such affirmative vote or consent of the holders of the
outstanding shares of Preferred Stock of any series, PNC may, by resolution of
its Board of Directors or as otherwise permitted by law, from time to time alter
or change the preferences, rights or powers of the Preferred Stock of such
series. The holders of the Preferred Stock of such series shall not be entitled
to participate in any such vote if, at or prior to the time when any such
alteration or change is to take effect, provision is made for the redemption of
all the Preferred Stock of such series at the time outstanding. See "Redemption
by PNC" below. Nothing in this section shall be taken to require a class vote or
consent in connection with the authorization, designation, increase or issuance
of any shares of any class or series (including additional Preferred Stock of
any series) that rank junior to or on a parity with the Preferred Stock of such
series as to dividends and liquidation rights or in connection with the
authorization, designation, increase or issuance of any bonds, mortgages,
debentures or other obligations of PNC.
 
     Under interpretations adopted by the Federal Reserve or its staff, if the
holders of Preferred Stock of any series become entitled to vote for the
election of directors because dividends on such series are in arrears as
described above, such series may then be deemed a "class of voting securities"
and a holder of 25% or more of such series (or a holder of 5% or more if it
otherwise exercises a "controlling influence" over PNC) may then be subject to
regulation as a bank holding company in accordance with the BHC Act. In
addition, at such time as such series is deemed a class of voting securities,
any other bank holding company may be required to obtain the prior approval of
the Federal Reserve to acquire more than 5% of such series, and any person other
than a bank holding company may be required to obtain the prior approval of the
Federal Reserve to acquire 10% or more of such series.
 
Liquidation of PNC
 
     In the event of voluntary or involuntary liquidation of PNC, the holders of
shares of each series of Preferred Stock shall be entitled to receive from the
assets of PNC (whether capital or surplus), prior to any payment to the holders
of Common Stock or of any class or series of stock of PNC ranking as to assets
subordinate to such series, the amount fixed by the Board of Directors for such
series and described in the applicable Prospectus Supplement, plus, in case
dividends on such series shall have been determined to be cumulative, an amount
equal to the accrued and unpaid dividends thereon (to the extent cumulative)
computed to the date on which payment thereof is made available, whether or not
earned or declared. After such payment to the holders of shares of such series,
any remaining balance shall be paid to the holders of Common Stock or of any
class or series of stock of PNC ranking as to assets subordinate to such series,
as they may be entitled. If, upon liquidation of PNC, its assets are not
sufficient to pay in full the amounts so payable to the holders of shares of all
series of Preferred Stock ranking equally as to assets, all such shares shall
participate ratably in the distribution of assets in proportion to the full
amounts to which they are
 
                                       21
<PAGE>   23
 
respectively entitled. Neither a merger nor a consolidation of PNC into or with
any other corporation nor a sale, transfer or lease of all or part of the assets
of PNC shall be deemed a liquidation of PNC within the meaning of this
paragraph.
 
Redemption by PNC
 
     Except as otherwise provided by the Board of Directors and described in the
applicable Prospectus Supplement, PNC, at its option to be exercised by its
Board of Directors, may redeem the whole or any part of the Preferred Stock or
of any series thereof at such times and at the applicable amount for each share
which shall have been fixed and determined, plus, in case dividends shall have
been determined to be cumulative, an amount equal to the accrued and unpaid
dividends thereon (to the extent cumulative) computed to the date fixed for
redemption, whether or not earned or declared (hereinafter collectively called
the "redemption price"). If at any time less than all of the Preferred Stock
then outstanding is to be called for redemption, the Board may select one or
more series to be redeemed, and if less than all the outstanding Preferred Stock
of any series is to be called for redemption, the shares to be redeemed may be
selected by lot or by such other equitable method as the Board in its discretion
may determine.
 
     Notice of redemption shall be published at least once in a newspaper of
general circulation in Philadelphia, Pennsylvania, or in the Borough of
Manhattan, New York, and copies of such notice shall be given by mailing the
same to each record holder of the Preferred Stock to be redeemed, not less than
30 nor more than 60 days prior to the date fixed for redemption thereof, to the
respective addresses of such holders as the same shall appear on the stock books
of PNC. Each notice shall state: (i) the redemption date; (ii) the number of
shares and series of the Preferred Stock to be redeemed; (iii) the redemption
price; and (iv) the place or places where certificates for such Preferred Stock
are to be surrendered for payment of the redemption price. If fewer than all the
shares of Preferred Stock of any series held by any holder are to be redeemed,
the notice mailed to such holder shall also specify the number of shares of
Preferred Stock to be redeemed from such holder.
 
     If notice of redemption of any share of Preferred Stock has been given,
from and after the redemption date for such shares (unless default shall be made
by PNC in providing money for the payment of the redemption price of such
shares), dividends on such shares shall cease to accrue and such shares shall no
longer be deemed to be outstanding, and all rights of the holders thereof as
shareholders of PNC (except the right to receive the redemption price) shall
cease. Failure to give notice by mail or any defect therein or failure of any
addressee to receive it shall not affect the validity of the proceedings for
redemption. Conversion rights of shares called for redemption shall terminate at
the close of business on the date fixed for redemption or at such earlier time
as shall have been fixed by the Board of Directors. Upon surrender in accordance
with such notice of the certificates representing any such shares (properly
endorsed or assigned for transfer, if the Board of Directors of PNC shall so
require and the notice shall so state), the redemption price set forth above
shall be paid out of the funds provided by PNC. If fewer than all the shares
represented by any such certificate are redeemed, a new certificate representing
the unredeemed shares shall be issued without cost to the holder thereof.
 
     Except as otherwise provided by the Board of Directors and described in the
applicable Prospectus Supplement, PNC shall have the right to acquire Preferred
Stock from time to time at such price or prices as PNC may determine, provided
that unless dividends (to the extent cumulative) payable for all past quarterly
dividend periods on all outstanding shares of Preferred Stock entitled to
cumulative dividends have been paid, or declared and set apart for payment, in
full, PNC shall not acquire for value any shares of Preferred Stock except in
accordance with an offer (which may vary as to terms offered with respect to
shares of different series but not with respect to shares of the same series)
made in writing or by publication (as determined by the Board of Directors) to
all holders of record of shares of Preferred Stock.
 
                                       22
<PAGE>   24
 
Conversion
 
     The holders of any series of Preferred Stock will have such rights, if any,
to convert such shares into or to exchange such shares for, cash, shares of
PNC's Common Stock or any other class of capital securities of PNC as may be set
forth in the Prospectus Supplement relating to such series of Preferred Stock.
 
PREFERRED STOCK CURRENTLY OUTSTANDING
 
     The following summaries of the outstanding Preferred Stock are qualified in
their entirety by reference to the corresponding Designations of Series and
description of Preferred Stock contained in PNC's Articles of Incorporation, as
amended, attached as Exhibits 99.1 and 99.2 (with respect to the Preferred
Stock-F) to PNC's Current Report on Form 8-K dated October 7, 1996 and PNC's
application for registration of securities on Form 8-A filed September 24, 1987
(File No. 1-9718) and incorporated herein by reference.
 
     Holders of outstanding Preferred Stock are entitled to cumulative dividends
at the annual rate of $1.80 per share for Preferred Stock-A, Preferred Stock-B
and Preferred Stock-D and $1.60 per share for Preferred Stock-C, payable
quarterly when and as declared by the Board of Directors of PNC. The Board of
Directors may not pay or set apart dividends on Common Stock until dividends for
the current period and all past dividend periods on all series of outstanding
Preferred Stock have been paid or declared and set apart for payment. Dividends
on Preferred Stock-F are payable quarterly at a rate per share of 6.05% per
annum through September 29, 2001, and thereafter at the "Applicable Rate" (as
defined in the Designation of Series relating to the Preferred Stock-F), which
rate will not be less than 6.55% nor greater than 12.55% (unless there are
certain changes made to the Internal Revenue Code). Dividends on the Preferred
Stock-F are not cumulative and no rights accrue to the holders by reason of the
fact that PNC may fail to declare or pay dividends on the Preferred Stock-F in
any amount in any year.
 
     Holders of outstanding Preferred Stock, other than Preferred Stock-F, are
entitled to a number of votes equal to the number of full shares of Common Stock
into which their Preferred Stock is at the time convertible. Holders of
outstanding Preferred Stock currently are entitled to the following conversion
privileges: (i) one share of Preferred Stock-A or Preferred Stock-B is
convertible into eight shares of Common Stock and (ii) 2.4 shares of Preferred
Stock-C or Preferred Stock-D are convertible into four shares of Common Stock.
Shares of Preferred Stock-F do not have voting rights, except in limited
circumstances.
 
     On the liquidation of PNC, holders of outstanding Preferred Stock would be
entitled to receive, before any payments are made with respect to Common Stock,
a specified amount for each share held by them, plus all dividends accrued and
unpaid thereon, or such lesser amount remaining after the claims of all
creditors have been satisfied, ratably with holders of other series of Preferred
Stock ranking equally as to assets. The liquidation preference is $40 per share
for Preferred Stock-A and Preferred Stock-B, $20 per share for Preferred Stock-C
and Preferred Stock-D and $50 per share for Preferred Stock-F.
 
     Preferred Stock-A, Preferred Stock-C and Preferred Stock-D are redeemable
at any time at the option of PNC at redemption prices equal to the respective
liquidation preference amounts stated above, plus accrued and unpaid dividends,
if any. Preferred Stock-B is not redeemable. Prior to September 30, 2001,
Preferred Stock-F is not redeemable, except in limited circumstances by PNC upon
certain changes to the Internal Revenue Code at a declining redemption price
ranging from $52.20 to the liquidation preference amount, plus accrued and
unpaid dividends (whether or not earned or declared) from the immediately
preceding dividend payment date (but without any cumulation for unpaid dividends
for prior dividend periods) to the date fixed for redemption. On and after
September 30, 2001, Preferred Stock-F is redeemable at the option of PNC at its
liquidation preference amount, plus accrued and unpaid dividends (whether or not
earned or declared) from the immediately preceding dividend payment date (but
without any cumulation for unpaid dividends for prior dividend periods) to the
date fixed for redemption.
 
     All outstanding series of Preferred Stock, other than Preferred Stock-F,
are convertible (unless called for redemption and not converted within the time
allowed therefor), at any time at the option of the holder. No adjustment will
be made for dividends on Preferred Stock converted or on Common Stock issuable
upon conversion. The conversion rate of each series of convertible Preferred
Stock will be adjusted in certain events,
 
                                       23
<PAGE>   25
 
including payment of stock dividends on, or splits or combinations of, the
Common Stock or issuance to holders of Common Stock of rights to purchase Common
Stock at a price per share less than 90% of Current Market Price as defined in
the Articles of Incorporation of PNC. Appropriate adjustments in the conversion
provisions also will be made in the event of certain reclassifications,
consolidations or mergers or the sale of substantially all of the assets of PNC.
Preferred Stock-F is not convertible into shares of Common Stock or any other
security of PNC.
 
     PNC shall have the right to acquire outstanding Preferred Stock from time
to time at such price or prices as PNC may determine, provided that unless
dividends (to the extent cumulative) payable for all past quarterly dividend
periods on all outstanding shares of Preferred Stock entitled to cumulative
dividends have been paid, or declared and set apart for payment, in full, PNC
shall not acquire for value any shares of Preferred Stock except in accordance
with an offer (which may vary as to terms offered with respect to shares of
different series but not with respect to shares of the same series) made in
writing or by publication (as determined by the Board of Directors) to all
holders of record of shares of Preferred Stock.
 
     Preferred Stock-A, Preferred Stock-B and Preferred Stock-F are currently
traded in the over-the-counter market. Preferred Stock-C and -D are listed and
traded on the New York Stock Exchange. The Chase Manhattan Bank, New York, New
York, is transfer agent and registrar for all outstanding series of Preferred
Stock.
 
                        DESCRIPTION OF DEPOSITARY SHARES
 
GENERAL
 
     Certain general terms and provisions of the Deposit Agreement (as described
below), the Depositary Shares and the Depositary Receipts to which a Prospectus
Supplement may relate are set forth below. The particular terms of the Preferred
Stock offered by any Prospectus Supplement and the extent, if any, to which such
general provisions may apply to the Depositary Shares will be described in the
Prospectus Supplement relating to such Preferred Stock. The descriptions below
and in any Prospectus Supplement do not purport to be complete and are subject
to and qualified in their entirety by reference to the Deposit Agreement and the
Depositary Receipts, the forms of which are incorporated by reference as
Exhibits 4.5 and 4.6, respectively, to the Registration Statement of which this
Prospectus is a part and the definitive forms of which will be filed with the
Commission.
 
     PNC may, at its option, elect to offer fractional interests in the
Preferred Stock, rather than whole shares of such securities. In the event such
option is exercised, PNC will provide for the issuance by a Depositary to the
public of receipts for Depositary Shares, each of which will represent a
fractional interest (to be set forth in the Prospectus Supplement relating to a
particular series of the Preferred Stock) in a share of a particular series of
the Preferred Stock as described below.
 
     The shares of any series of the Preferred Stock underlying the Depositary
Shares will be deposited under a separate Deposit Agreement ("Deposit
Agreement") between PNC and a bank or trust company selected by PNC having its
principal office in the United States and having a combined capital and surplus
of at least $50,000,000 ("Depositary"). The Prospectus Supplement relating to a
series of Depositary Shares will set forth the name and address of the
Depositary, which may be one of the Banks. Subject to the terms of the Deposit
Agreement, each owner of a Depositary Share will be entitled, in proportion to
the applicable fractional interest in a share of Preferred Stock underlying such
Depositary Share, to all the rights and preferences of the Preferred Stock
underlying such Depositary Share (including dividend, voting, redemption,
conversion and liquidation rights).
 
     The Depositary Shares will be evidenced by Depositary Receipts issued
pursuant to the Deposit Agreement. Depositary Receipts will be distributed to
those persons purchasing the fractional shares of the related series of
Preferred Stock in accordance with the terms of the offering described in a
related Prospectus Supplement.
 
                                       24
<PAGE>   26
 
     Pending the preparation of definitive engraved Depositary Receipts, the
Depositary may, upon the written order of PNC, issue temporary Depositary
Receipts substantially identical to (and entitling the holders thereof to all
the rights pertaining to) the definitive Depositary Receipts but not in
definitive form. Definitive Depositary Receipts will be prepared thereafter
without unreasonable delay and temporary Depositary Receipts will be
exchangeable for definitive Depositary Receipts at PNC's expense.
 
     Upon surrender of Depositary Receipts at the office of the Depositary
(unless the Depositary Shares have been previously called for redemption) and
upon payment of the charges provided in the Deposit Agreement and subject to the
terms thereof, a holder of Depositary Shares is entitled to have the Depositary
deliver to such holder the number of whole shares of the related Preferred Stock
underlying the Depositary Shares evidenced by the surrendered Depositary
Receipts. Partial shares of Preferred Stock will not be issued. Holders of
Depositary Shares will be entitled to receive shares of the related series of
Preferred Stock as set forth in a related Prospectus Supplement, but holders of
such whole shares of such Preferred Stock thus withdrawn will not thereafter be
entitled to receive Depositary Shares therefor. If the Depositary Receipts
delivered by the holder evidence a number of Depositary Shares in excess of the
number of Depositary Shares representing the number of whole shares of the
related series of Preferred Stock to be withdrawn, the Depositary will deliver
to such holder at the same time a new Depositary Receipt evidencing such excess
number of Depositary Shares. PNC does not expect that there will be any public
trading market for the withdrawn shares.
 
DIVIDENDS AND OTHER DISTRIBUTIONS
 
     The Depositary will distribute all cash dividends or other cash
distributions received in respect of the Preferred Stock to the record holders
of Depositary Shares relating to such Preferred Stock in proportion to the
numbers of such Depositary Shares owned by such holders on the relevant record
date. The Depositary shall distribute only such amount, however, as can be
distributed without attributing to any holder of Depositary Shares a fraction of
one cent, and any balance not so distributed shall be added to and treated as
part of the next sum received by the Depositary for distribution to record
holders of Depositary Shares.
 
     In the event of a distribution other than in cash, the Depositary will
distribute property received by it to the record holders of Depositary Shares
entitled thereto, unless the Depositary determines that it is not feasible to
make such distribution, in which case the Depositary may, with the approval of
PNC, sell such property and distribute the net proceeds from such sale to such
holders.
 
REDEMPTION OF DEPOSITARY SHARES
 
     If a series of the Preferred Stock underlying the Depositary Shares is
subject to redemption, the Depositary Shares will be redeemed from the proceeds
received by the Depositary resulting from the redemption, in whole or in part,
of such series of the Preferred Stock held by the Depositary. The Depositary
shall mail notice of redemption not less than 30 and not more than 60 days prior
to the date fixed for redemption to the record holders of the Depositary Shares
to be so redeemed at their respective addresses appearing in the Depositary's
books. The redemption price per Depositary Share will be equal to the applicable
fraction of the redemption price per share payable with respect to such series
of the Preferred Stock. Whenever PNC redeems Preferred Stock held by the
Depositary, the Depositary will redeem as of the same redemption date the number
of Depositary Shares relating to the shares of Preferred Stock so redeemed. If
less than all the Depositary Shares are to be redeemed, the Depositary Shares to
be redeemed will be selected by lot or pro rata as may be determined by the
Depositary.
 
     After the date fixed for redemption, the Depositary Shares so called for
redemption will no longer be deemed to be outstanding and all rights of the
holder of the Depositary Shares will cease, except the right to receive the
monies payable upon such redemption and any money or other property to which the
holders of such Depositary Shares were entitled upon such redemption upon
surrender to the Depositary of the Depositary Receipts evidencing such
Depositary Shares.

VOTING THE PREFERRED STOCK
 
     Upon receipt of notice of any meeting at which the holders of the Preferred
Stock are entitled to vote, the Depositary will mail the information contained
in such notice of meeting to the record holders of the Depositary Shares
relating to such Preferred Stock. Each record holder of such Depositary Shares
on the record date (which will be the same date as the record date for the
Preferred Stock) will be entitled to instruct the Depositary as to the exercise
of the voting rights pertaining to the amount of Preferred Stock underlying such
holder's Depositary Shares. The Depositary will endeavor, insofar as
practicable, to vote the amount of Preferred Stock underlying such Depositary
Shares in accordance with such instructions, and PNC will agree to take all
action which may be deemed necessary by the Depositary in order to enable the
Depositary to do so. The Depositary will abstain from voting Preferred Stock to
the extent it does not receive specific instructions from the holders of
Depositary Shares relating to such Preferred Stock.
 
CONVERSION OF PREFERRED STOCK
 
     If a series of the Preferred Stock underlying the Depositary Shares is
convertible into shares of PNC's Common Stock or any other class of capital
securities of PNC, PNC will accept the delivery of Depositary Receipts for
purposes of effecting conversions of the Preferred Stock utilizing the same
procedures as those provided for delivery of certificates for the Preferred
Stock pursuant to the terms of the series of Preferred Stock. If the Depositary
Shares represented by a Depositary Receipt are to be converted in part only, a
new Depositary Receipt or Depositary Receipts will be issued by the Depositary
for the Depositary Shares not to be converted.
 
AMENDMENT AND TERMINATION OF THE DEPOSIT AGREEMENT
 
     The form of Depositary Receipt evidencing the Depositary Shares and any
provision of the Deposit Agreement may at any time be amended by agreement
between PNC and the Depositary. However, any amendment which materially and
adversely alters the rights of the existing holders of Depositary Shares will
not be effective unless such amendment has been approved by the record holders
of at least a majority of the Depositary Shares then outstanding. A Deposit
Agreement may be terminated by PNC or the Depositary only if (i) all outstanding
Depositary Shares relating thereto have been redeemed or (ii) there has been a
final distribution in respect of the Preferred Stock of the relevant series in
connection with any liquidation, dissolution or winding up of PNC.
 
CHARGES OF DEPOSITARY
 
     PNC will pay all transfer and other taxes and governmental charges arising
solely from the existence of the depositary arrangements. PNC will also pay
charges of the Depositary in connection with the initial deposit of the
Preferred Stock and any redemption of the Preferred Stock. Holders of Depositary
Shares will pay other transfer and other taxes and governmental charges and such
other charges as are expressly provided in the Deposit Agreement to be for their
accounts.
 
MISCELLANEOUS
 
     The Depositary will forward to the holders of Depositary Shares all reports
and communications from PNC which are delivered to the Depositary and which PNC
is required to furnish to the holders of the Preferred Stock.
 
     Neither the Depositary nor PNC will be liable if it is prevented or delayed
by law or any circumstance beyond its control in performing its obligations
under the Deposit Agreement. The obligations of PNC and the Depositary under the
Deposit Agreement will be limited to performance in good faith of their
respective duties thereunder and they will not be obligated to prosecute or
defend any legal proceeding in respect of any Depositary Shares or shares of
Preferred Stock unless satisfactory indemnity is furnished. They may rely upon
written advice of counsel or accountants, or information provided by persons
presenting Preferred Stock for deposit, holders of Depositary Shares or other
persons believed to be competent and on documents believed to be genuine.

RESIGNATION AND REMOVAL OF DEPOSITARY
 
     The Depositary may resign at any time by delivering to PNC notice of its
election to do so, and PNC may at any time remove the Depositary, any such
resignation or removal to take effect only upon the appointment of a successor
Depositary and its acceptance of such appointment. Such successor Depositary
must be a bank or trust company having its principal office in the United States
and having a combined capital and surplus of at least $50,000,000.
 
                              PLAN OF DISTRIBUTION
 
     PNC Funding may offer and sell Debt Securities to or through underwriters,
acting as principals for their own accounts or as agents, and also may offer and
sell Debt Securities directly to other purchasers. PNC may offer and sell Common
Stock and Preferred Stock to or through underwriters, acting as principals for
their own accounts or as agents, and also may offer and sell Common Stock and
Preferred Stock directly to other purchasers. Any underwriters in connection
with Offered Debt Securities, Common Stock or Preferred Stock will be named in
the related Prospectus Supplement and any underwriting compensation paid to such
underwriters will be set forth therein. Underwritten offerings may involve
underwriting syndicates represented by managing underwriters, or underwriters
without a syndicate.
 
     The distribution of Securities may be effected from time to time in one or
more transactions at a fixed price or prices, which may be changed, or at market
prices prevailing at the time of sale, at prices related to such prevailing
market prices or at negotiated prices.
 
     In connection with the sale of Securities, underwriters or agents acting on
PNC's behalf may receive compensation from PNC Funding, PNC or from purchasers
of Securities for whom they may act as agents, in the form of discounts,
concessions or commissions. The underwriters, dealers or agents that participate
in the distribution of Securities may be deemed to be underwriters and any
discounts or commissions received by them and any profit on the resale of
Securities by them may be deemed to be underwriting discounts and commissions
under the Securities Act. Any such underwriter will be identified and any such
compensation will be described in the Prospectus Supplement.
 
     Under agreements which may be entered into with PNC Funding and PNC,
underwriters, dealers and agents may be entitled to indemnification by PNC
Funding or PNC against certain liabilities, including liabilities under the
Securities Act, and to contributions from PNC Funding or PNC in respect of such
liabilities. Underwriters, dealers and agents may be customers of, engage in
transactions with, or perform services for PNC Funding or PNC in the ordinary
course of business.
 
     If so indicated in the Prospectus Supplement, PNC Funding and/or PNC will
authorize underwriters or other persons acting as PNC Funding's agents and/or
PNC's agents to solicit offers by certain institutions to purchase Debt
Securities from PNC Funding and/or Preferred Stock from PNC pursuant to
contracts providing for payment and delivery on a future date or dates stated in
the applicable Prospectus Supplement. Institutions with which such contracts may
be made include commercial and savings banks, insurance companies, pension
funds, investment companies, educational and charitable institutions and others,
but in all cases such institutions must be approved by PNC Funding or PNC. The
obligations of any purchaser under any such contract will not be subject to any
conditions, except that (1) the purchase of the Debt Securities, or the Common
Stock or the Preferred Stock shall not at the time of delivery be prohibited
under the laws of the jurisdiction to which such purchaser is subject, and (2)
if Debt Securities or Common Stock or Preferred Stock are also being sold to
underwriters, PNC Funding or PNC shall have sold to such underwriters the Debt
Securities or the Common Stock or the Preferred Stock not sold for delayed
delivery. The underwriters and such other persons will not have any
responsibility in respect of the validity or performance of such contracts.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Sections 1741-1743 of the Pennsylvania Business Corporation Law of 1988
(Act of December 21, 1988, P.L. 1444) ("1988 BCL") provide that a business
corporation may indemnify directors and officers against liabilities they may
incur in such capacities provided certain standards are met, including good
faith and the belief that the particular action is in the best interests of the
corporation. In general, this power to indemnify does not exist in the case of
actions against a director or officer by or in the right of the corporation if
the person entitled to indemnification shall have been adjudged to be liable for
negligence or misconduct in the performance of such person's duties. A
corporation is required to indemnify directors and officers against expenses
they may incur in defending actions against them in such capacities if they are
successful on the merits or otherwise in the defense of such actions.
 
     Section 1746 of the 1988 BCL provides that the foregoing provisions shall
not be deemed exclusive of any other rights to which a person seeking
indemnification may be entitled under, among other things, any by-law provision,
provided that no indemnification may be made in any case where the act or
failure to act giving rise to the claim for indemnification is determined by a
court to have constituted willful misconduct or recklessness.
 
     Each of PNC Bank Corp.'s and PNC Funding Corp's By-Laws provide for the
mandatory indemnification of directors and officers in accordance with and to
the full extent permitted by the Laws of Pennsylvania as in effect at the time
of such indemnification. Each of PNC Bank Corp.'s and PNC Funding Corp's By-Laws
also eliminate, to the maximum extent permitted by the laws of the Commonwealth
of Pennsylvania, the personal liability of directors for monetary damages for
any action taken, or any failure to take any action as a director except in any
case such elimination is not permitted by law.
 
     PNC Bank Corp. has purchased directors' and officers' liability insurance
covering certain liabilities which may be incurred by its respective officers
and directors in connection with the performance of their duties. Such insurance
covers PNC Funding Corp's directors and officers as well.
 
ITEM 16. EXHIBITS
 
     The exhibits listed on the Exhibit Index beginning on page II-6 of this
Registration Statement are filed herewith, will be filed by amendment, or are
incorporated herein by reference to other filings.

ITEM 17. UNDERTAKINGS
 
     The undersigned Registrants hereby undertake:
 
1. To file, during any period in which offers or sales are being made, a
   post-effective amendment to this Registration Statement:
 
  (i)  To include any prospectus required by Section 10(a) (3) of the Securities
       Act of 1933;
 
  (ii)  To reflect in the prospectus any facts or events arising after the
        effective date of the Registration Statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the Registration Statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than 20 percent change in
        the maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement;
 
  (iii) To include any material information with respect to the plan of
        distribution not previously disclosed in the Registration Statement or
        any material change to such information in the Registration Statement;
        provided, however, that paragraphs (i) and (ii) do not apply if the
        information required to be included in a post-effective amendment by
        those paragraphs is contained in periodic reports filed by the
        Registrants pursuant to Section 13 or Section 15(d) of the Securities
        Exchange Act of 1934, that are incorporated by reference in the
        Registration Statement.
 
2. That, for the purpose of determining any liability under the Securities Act
   of 1933, each such post-effective amendment shall be deemed to be a new
   registration statement relating to the securities offered therein, and the
   offering of such securities at that time shall be deemed to be the initial
   bona fide offering thereof;
 
3. To remove from the registration by means of a post-effective amendment any of
   the securities being registered which remain unsold at the termination of the
   offering;
 
4. That, for purposes of determining any liability under the Securities Act of
   1933, each filing of the Registrants' annual reports pursuant to Section
   13(a) or Section 15(d) of the Securities Exchange Act of 1934, that is
   incorporated by reference in the Registration Statement shall be deemed to be
   a new registration statement relating to the securities offered therein, and
   the offering of such securities at that time shall be deemed to be the
   initial bona fide offering thereof;
 
5. For the 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 Registrants 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 is declared effective; and
 
6. 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.
 
Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
Registrants pursuant to the provisions set forth in Item 15, or otherwise, the
Registrants have been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act of 1933 and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrants of expenses incurred or paid by a director, officer or
controlling person of the Registrants 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 Registrants will, unless
in the opinion of their counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933, and will be governed by the final adjudication of such
issue.

                             Underwriting Agreement

                                        New York, New York
                                        [date]

To the Representatives
  named in Schedule I
  hereto of the
  Underwriters named in
  Schedule II hereto

Dear Sirs:

          PNC Funding Corp, a Pennsylvania corporation (the "Company"),
proposes to sell to the underwriters named in Schedule II hereto (the
"Underwriters"), for whom you are acting as representatives (the
"Representatives"), the principal amount of its securities identified in
Schedule I hereto (together with the guarantees mentioned below, the
"Securities") to be guaranteed by PNC Bank Corp., a Pennsylvania Corporation
(the "Guarantor"), and to be issued under an indenture dated as of December 1,
1991, among the Company, the Guarantor and The Chase Manhattan Bank (formerly
known as Chemical Bank, successor by merger to Manufacturers Hanover Trust
Company), as trustee (the "Trustee"), as amended by a Supplemental Indenture
dated as of February 15, 1993, among the Company, the Guarantor and the Trustee
(as amended, the "Indenture"). If the firm or firms listed in Schedule II
hereto include only the firm or firms listed in Schedule I hereto, then the
terms "Underwriters" and "Representatives," as used herein, shall each be
deemed to refer to such firm or firms.

          1.  Representations and Warranties. The Company and the Guarantor
represent and warrant to, and agree with, each Underwriter as set forth below
in this Section 1. Certain terms used in this Section 1 are defined in
paragraph (c) hereof.

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


<PAGE>   2
                                     - 2 -

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

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

               (ii) The Company and the Guarantor meet the requirements for the
          use of Form S-3 under


<PAGE>   3
                                     - 3 -

          the Act and have filed with the Commission a registration statement
          (the file number of which is set forth in Schedule I hereto) on such
          Form, including a basic prospectus, for registration under the Act of
          the offering and sale of the Securities. The Company and the
          Guarantor may have filed one or more amendments thereto, including a
          Preliminary Final Prospectus, each of which has previously been
          furnished to you.  The Company and the Guarantor will next file with
          the Commission either (x) a final prospectus supplement relating to
          the Securities in accordance with Rules 430A and 424(b)(1) or (4), or
          (y) prior to the effectiveness of such registration statement, an
          amendment to such registration statement, including the form of final
          prospectus supplement. In the case of clause (x), the Company and the
          Guarantor included in such registration statement, as amended at the
          Effective Date, all information (other than Rule 430A Information)
          required by the Act and the rules thereunder to be included in the
          Final Prospectus with respect to the Securities and the offering
          thereof. As filed, such final prospectus supplement or such amendment
          and form of final prospectus supplement shall contain all Rule 430A
          Information, together with all other such required information, with
          respect to the Securities and the offering thereof and, except to the
          extent the Representatives shall agree in writing to a modification,
          shall be in all substantive respects in the form furnished to you
          prior to the Execution Time or, to the extent not completed at the
          Execution Time, shall contain only such specific additional
          information and other changes (beyond that contained in the Basic
          Prospectus and any Preliminary Final Prospectus) as the Company has
          advised you, prior to the Execution Time, will be included or made
          therein.

          (b) On the Effective Date, the Registration Statement did or will,
     and when the Final Prospectus is first filed (if required) in accordance
     with Rule 424(b) and on the Closing Date, the Final Prospectus (and any
     supplement thereto) will, comply in all material respects with the
     applicable requirements of the Act and the


<PAGE>   4
                                     - 4 -


     Securities Exchange Act of 1934 (the "Exchange Act") and the respective
     rules thereunder; on the Effective Date, the Registration Statement did
     not or will not contain any untrue statement of a material fact or omit to
     state any material fact required to be stated therein or necessary in
     order to make the statements therein not misleading; and, on the Effective
     Date, the Final Prospectus, if not filed pursuant to Rule 424(b), did not
     or will not, and on the date of any filing pursuant to Rule 424(b) and on
     the Closing Date, the Final Prospectus (together with any supplement
     thereto) will not, include any 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 Company and the Guarantor make no
     representations or warranties as to (i) that part of the Registration
     Statement which shall constitute the Statement of Eligibility and
     Qualification (Form T-1) under the Trust Indenture Act of the Trustee or
     (ii) the information contained in or omitted from the Registration
     Statement or the Final Prospectus (or any supplement thereto) in reliance
     upon and in conformity with information furnished in writing to the
     Company or the Guarantor by or on behalf of any Underwriter through the
     Representatives specifically for use in connection with the preparation of
     the Registration Statement or the Final Prospectus (or any supplement
     thereto).

          (c) The terms which follow, when used in this Agreement, shall have
     the meanings indicated. The term "the Effective Date" shall mean each date
     that the Registration Statement and any post effective amendment or
     amendments thereto became or become effective. "Execution Time" shall mean
     the date and time that this Agreement is executed and delivered by the
     parties hereto. "Basic Prospectus" shall mean the prospectus referred to
     in paragraph (a) above contained in the Registration Statement at the
     Effective Date including, in the case of a Non-Delayed Offering, any
     Preliminary Final Prospectus. "Preliminary Final Prospectus" shall mean
     any preliminary prospectus supplement to the Basic Prospectus which
     describes the Securities and the offering thereof and is used prior to
     filing of the Final Prospectus. "Final Prospectus" shall mean the


<PAGE>   5
                                     - 5 -


     prospectus supplement relating to the Securities that is first filed
     pursuant to Rule 424(b) after the Execution Time, together with the Basic
     Prospectus or, if, in the case of a Non-Delayed Offering, no filing
     pursuant to Rule 424(b) is required, shall mean the form of final
     prospectus relating to the Securities, including the Basic Prospectus,
     included in the Registration Statement at the Effective Date.
     "Registration Statement" shall mean the registration statement referred to
     in paragraph (a) above, including incorporated documents, exhibits and
     financial statements, as amended at the Execution Time (or, if not
     effective at the Execution Time, in the form in which it shall become
     effective) and, in the event any post effective amendment thereto becomes
     effective prior to the Closing Date (as hereinafter defined), shall also
     mean such registration statement as so amended. Such term shall include
     any Rule 430A Information deemed to be included therein at the Effective
     Date as provided by Rule 430A. "Rule 415," "Rule 424," "Rule 430A" and
     "Regulation S-K" refer to such rules or regulation under the Act. "Rule
     430A Information" means information with respect to the Securities and the
     offering thereof permitted to be omitted from the Registration Statement
     when it becomes effective pursuant to Rule 430A. Any reference herein to
     the Registration Statement, the Basic Prospectus, any Preliminary Final
     Prospectus or the Final Prospectus shall be deemed to refer to and include
     the documents incorporated by reference therein pursuant to Item 12 of
     Form S-3 which were filed under the Exchange Act on or before the
     Effective Date of the Registration Statement or the issue date of the
     Basic Prospectus, any Preliminary Final Prospectus or the Final
     Prospectus, as the case may be; and any reference herein to the terms
     "amend," "amendment" or "supplement" with respect to the Registration
     Statement, the Basic Prospectus, any Preliminary Final Prospectus or the
     Final Prospectus shall be deemed to refer to and include the filing of any
     document under the Exchange Act after the Effective Date of the
     Registration Statement or the issue date of the Basic Prospectus, any
     Preliminary Final Prospectus or the Final Prospectus, as the case may be,
     deemed to be incorporated therein by reference. A "Non-Delayed Offering"
     shall mean an offering of securities which is intended to commence
     promptly after the effective date of a registration statement, with


<PAGE>   6
                                     - 6 -



     the result that, pursuant to Rules 415 and 430A, all information (other
     than Rule 430A Information) with respect to the securities so offered must
     be included in such registration statement at the effective date thereof.
     A "Delayed Offering" shall mean an offering of securities pursuant to Rule
     415 which does not commence promptly after the effective date of a
     registration statement, with the result that only information required
     pursuant to Rule 415 need be included in such registration statement at
     the effective date thereof with respect to the securities so offered.
     Whether the offering of the Securities is a Non-Delayed Offering or a
     Delayed Offering shall be set forth in Schedule I hereto.

          2.  Purchase and Sale. Subject to the terms and conditions and in
reliance upon the representations and warranties herein set forth, the Company
agrees to, and the Guarantor agrees to cause the Company to, sell to each
Underwriter, and each Underwriter agrees, severally and not jointly, to
purchase from the Company, at the purchase price set forth in Schedule I hereto
the number of shares of the Securities set forth opposite such Underwriter's
name in Schedule II hereto, except that, if Schedule I hereto provides for the
sale of Securities pursuant to delayed delivery arrangements, the respective
principal amounts of Securities to be purchased by the Underwriters shall be as
set forth in Schedule II hereto less the respective amounts of Contract
Securities determined as provided below. Securities to be purchased by the
Underwriters are herein sometimes called the "Underwriters' Securities" and
Securities to be purchased pursuant to Delayed Delivery Contracts as
hereinafter provided are herein called "Contract Securities."

          If so provided in Schedule I hereto, the Underwriters are authorized
to solicit offers to purchase Securities from the Company pursuant to delayed
delivery contracts ("Delayed Delivery Contracts"), substantially in the form of
Schedule III hereto but with such changes therein as the Company and the
Guarantor may authorize or approve. The Underwriters will endeavor to make such
arrangements and, as compensation therefor, the Company will pay, and the
Guarantor will cause the Company to pay, to the Representatives, for the
account of the Underwriters, on the Closing Date, the percentage set forth in
Schedule I hereto of the principal amount of the Securities for which Delayed
Delivery Contracts are made. Delayed


<PAGE>   7
                                     - 7 -


Delivery Contracts are to be with institutional investors, including commercial
and savings banks, insurance companies, pension funds, investment companies and
educational and charitable institutions. The Company will enter into, and the
Guarantor will cause the Company to enter into, Delayed Delivery Contracts in
all cases where sales of Contract Securities arranged by the Underwriters have
been approved by the Company but, except as the Company may otherwise agree,
each such Delayed Delivery Contract must be for not less than the minimum
principal amount set forth in Schedule I hereto and the aggregate principal
amount of Contract Securities may not exceed the maximum aggregate principal
amount set forth in Schedule I hereto. The Underwriters will not have any
responsibility in respect of the validity or performance of Delayed Delivery
Contracts. The principal amount of Securities to be purchased by each
Underwriter as set forth in Schedule II hereto shall be reduced by an amount
which shall bear the same proportion to the total principal amount of Contract
Securities as the principal amount of Securities set forth opposite the name of
such Underwriter bears to the aggregate principal amount set forth in Schedule
II hereto, except to the extent that you determine that such reduction shall be
otherwise than in such proportion and so advise the Company in writing;
provided, however, that the total principal amount of Securities to be
purchased by all Underwriters shall be the aggregate principal amount set forth
in Schedule II hereto less the aggregate principal amount of Contract
Securities.

          3.  Delivery and Payment. Delivery of and payment for the
Underwriters' Securities shall be made on the date and at the time specified in
Schedule I hereto (or such later date not later than five business days after
such specified date as the Representatives shall designate), which date and
time may be postponed by agreement among the Representatives, the Company and
the Guarantor or as provided in Section 8 hereof (such date and time of
delivery and payment for the Underwriters' Securities being herein called the
"Closing Date"). Delivery of the Underwriters' Securities shall be made to the
Representatives for the respective accounts of the several Underwriters against
payment by the several Underwriters through the Representatives of the purchase
price thereof to or upon the order of the Company by wire transfer of
immediately available funds. Delivery of the Underwriters' Securities shall be
made at such location in The City of New York as the Representatives shall
reasonably


<PAGE>   8
                                     - 8 -




designate at least one business day in advance of the Closing Date and payment
for the Securities shall be made at the office specified in Schedule I hereto.
Certificates for the Underwriters' Securities shall be registered in such names
(including the nominee for any depositary which will hold Securities to be
established for "book entry" issuance and transfer) and in such denominations
as the Representatives may request not less than two full business days in
advance of the Closing Date.

          The Company and the Guarantor agree to have the Underwriters'
Securities available for inspection, checking and packaging by the
Representatives in New York, New York, not later than 1:00 p.m. on the business
day prior to the Closing Date.

          4.  Agreements.  The Company and the Guarantor jointly and severally
agree with the several Underwriters that:

          (a) The Company and the Guarantor will use their best efforts to
     cause the Registration Statement, if not effective at the Execution Time,
     and any amendment thereto, to become effective. Prior to the termination
     of the offering of the Securities, the Company and the Guarantor will not
     file any amendment to the Registration Statement or supplement (including
     the Final Prospectus or any Preliminary Final Prospectus) to the Basic
     Prospectus unless the Company and the Guarantor have furnished you a copy
     for your review prior to filing and will not file any such proposed
     amendment or supplement to which you reasonably object. Subject to the
     foregoing sentence, the Company and the Guarantor will cause the Final
     Prospectus, properly completed, and any supplement thereto to be filed
     with the Commission pursuant to the applicable paragraph of Rule 424(b)
     within the time period prescribed and will provide evidence satisfactory
     to the Representatives of such timely filing. The Company and the
     Guarantor will promptly advise the Representatives (i) when the
     Registration Statement, if not effective at the Execution Time, and any
     amendment thereto, shall have become effective, (ii) when the Final
     Prospectus, and any supplement thereto, shall have been filed with the
     Commission pursuant to Rule 424(b), (iii) when, prior to termination of
     the offering of the Securities, any amendment to the Registration
     Statement shall have been filed or


<PAGE>   9
                                     - 9 -


     become effective, (iv) of any request by the Commission for any amendment
     of the Registration Statement or supplement to the Final Prospectus or for
     any additional information, (v) of the issuance by the Commission of any
     stop order suspending the effectiveness of the Registration Statement or
     the institution or threatening of any proceeding for that purpose and (vi)
     of the receipt by the Company or the Guarantor of any notification with
     respect to the suspension of the qualification of the Securities for sale
     in any jurisdiction or the initiation or threatening of any proceeding for
     such purpose. The Company and the Guarantor will use their best efforts to
     prevent the issuance of any such stop order and, if issued, to obtain as
     soon as possible the withdrawal thereof.

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

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

          (d) The Company and the Guarantor will furnish to the Representatives
     and counsel for the Underwriters, without charge, copies of the
     Registration Statement (including exhibits thereto) and, so long as
     delivery of a prospectus by an Underwriter or dealer may be required by
     the Act, as many copies of any Preliminary Final Prospectus and the Final
     Prospectus and any supplement thereto


<PAGE>   10
                                     - 10 -



     as the Representatives may reasonably request. The Company and the
     Guarantor will pay the expenses of printing or other production of all
     documents relating to the offering.

          (e) The Company and the Guarantor will use their best efforts to
     arrange for the qualification of the Securities for sale under the laws of
     such jurisdictions as the Representatives may designate, will maintain
     such qualifications in effect so long as required for the distribution of
     the Securities and will arrange for the determination of the legality of
     the Securities for purchase by institutional investors; provided, however,
     that neither the Company nor the Guarantor shall be required to qualify to
     do business in any jurisdiction where it is not now qualified or to take
     any action which would subject it to general or unlimited service of
     process in any jurisdiction where they are not now subject.

          (f) Until the business day following the Closing Date, the Company
     and the Guarantor will not, without the consent of the Representatives,
     offer, sell or contract to sell, or announce the offering of, any debt
     securities covered by the Registration Statement or any other registration
     statement filed under the Act.

          5.  Conditions to the Obligations of the Underwriters. The
obligations of the Underwriters to purchase the Underwriters' Securities shall
be subject to the accuracy in all material respects of the representations and
warranties on the part of the Company and the Guarantor contained herein as of
the Execution Time and the Closing Date, to the accuracy in all material
respects of the statements of the Company and the Guarantor made in any
certificates pursuant to the provisions hereof, to the performance in all
material respects by the Company and the Guarantor of their obligations
hereunder and to the following additional conditions:

          (a) If the Registration Statement has not become effective prior to
     the Execution Time, unless the Representatives agree in writing to a later
     time, the Registration Statement will become effective not later than (i)
     6:00 p.m. New York City time, on the date of determination of the public
     offering price, if such determination occurred at or prior to 3:00 p.m.
     New York City


<PAGE>   11
                                     - 11 -


     time on such date or (ii) 12:00 Noon on the business day following the day
     on which the public offering price was determined, if such determination
     occurred after 3:00 p.m. New York City time on such date; if filing of the
     Final Prospectus, or any supplement thereto, is required pursuant to Rule
     424(b), the Final Prospectus, and any such supplement, shall have been
     filed in the manner and within the time period required by Rule 424(b);
     and no stop order suspending the effectiveness of the Registration
     Statement shall have been issued and no proceedings for that purpose shall
     have been instituted or threatened.

          (b) The Company and the Guarantor shall have furnished to the
     Representatives the opinion of Melanie S. Cibik, Esq., Senior Counsel of
     the Guarantor, dated the Closing Date, to the effect that:

               (i)  Each of the Company and the Guarantor is a corporation
          validly organized and presently subsisting under the laws of the
          Commonwealth of Pennsylvania with all requisite corporate power and
          authority to own its properties and conduct its business as described
          in the Final Prospectus, except for such power and authority the
          absence of which would not have a material adverse effect on the
          Guarantor or the Company, as the case may be; and the Guarantor is
          duly registered as a bank holding company under the Bank Holding
          Company Act of 1956, as amended;

               (ii)  PNC Bank, National Association ("PNC Bank, N.A.") is a
          national banking organization validly existing in good standing under
          the laws of the United States, with all requisite corporate power and
          authority to own, lease and operate its properties and conduct its
          business as described in the Final Prospectus, except for such power
          and authority the absence of which would not have a material adverse
          effect on PNC Bank, N.A.;

               (iii)  all the outstanding shares of capital stock of PNC Bank,
          N.A. have been duly and validly authorized and issued and (except as
          provided in 12 U.S.C. Section 55) are fully paid and nonassessable, 
          and, except as otherwise set forth in the Final Prospectus, all


<PAGE>   12
                                     - 12 -




          outstanding shares of capital stock of PNC Bank, N.A. are owned by
          the Guarantor either directly or through wholly owned subsidiaries
          free and clear of any perfected security interest and, to the
          knowledge of such counsel, any other security interests, claims,
          liens or encumbrances;

               (iv)  the Guarantor's authorized equity capitalization, if set
          forth in the Final Prospectus, is as set forth in the Final
          Prospectus; the Securities conform in all material respects to the
          description thereof contained in the Final Prospectus; and, if the
          Securities are to be listed on any stock exchange, authorization
          therefor has been given, subject to official notice of issuance and
          evidence of satisfactory distribution, or the Company and the
          Guarantor have filed a preliminary listing application and all
          required supporting documents with respect to the Securities with
          such stock exchange and nothing has caused such counsel to believe
          that the Securities will not be authorized for listing, subject to
          official notice of issuance and evidence of satisfactory
          distribution;

               (v)  the Indenture has been duly authorized, executed and
          delivered, has been duly qualified under the Trust Indenture Act, and
          constitutes a legal, valid and binding instrument enforceable against
          the Company in accordance with its terms, except as such
          enforceability may be limited by applicable bankruptcy, insolvency,
          receivership, readjustment of debt, fraudulent conveyance,
          reorganization, moratorium and other similar laws relating to or
          affecting creditors' rights generally or general equitable principles
          (whether considered in a proceeding in equity or at law); and the
          Securities have been duly authorized and, when executed and
          authenticated in accordance with the provisions of the Indenture and
          delivered to and paid for by the Underwriters pursuant to this
          Agreement, in the case of the Underwriters' Securities, or by the
          purchasers thereof pursuant to Delayed Delivery Contracts, in the
          case of any Contract Securities, will constitute legal, valid and

                                     - 13 -




          binding obligations of the Company and the Guarantor entitled to the
          benefits of the Indenture;

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

               (vii)  the Registration Statement has become effective under the
          Act; any required filing of the Basic Prospectus, any Preliminary
          Final Prospectus and the Final Prospectus, and any supplements
          thereto, pursuant to Rule 424(b) has been made in the manner and
          within the time period required by Rule 424(b); to the best knowledge
          of such counsel, no stop order suspending the effectiveness of the
          Registration Statement has been issued, no proceedings for that
          purpose have been instituted or threatened, and the Registration
          Statement and the Final Prospectus (other than the financial
          statements and other financial and statistical information contained
          or incorporated therein, and that part of the Registration Statement
          which constitutes the Statement of Eligibility and Qualification
          (Form T-1) of the Trustee under the Trust Indenture Act, as to which
          such counsel need express no opinion) comply as to form in all
          material respects with the applicable requirements of that Act and
          the Exchange Act and the respective rules thereunder; and nothing has
          come to the attention of such counsel that has caused such


<PAGE>   14
                                     - 14 -




          counsel to believe that at the Effective Date the Registration
          Statement contained any untrue statement of a material fact or
          omitted to state any material fact required to be stated therein or
          necessary to make the statements therein not misleading or that the
          Final Prospectus includes any untrue statement of a material fact or
          omits to state a material fact necessary to make the statements
          therein, in the light of the circumstances under which they were
          made, not misleading except that such counsel does not express any
          opinion or belief as to the financial statements or schedules or
          other data of a statistical or financial nature included or
          incorporated therein or as to that part of the Registration Statement
          which constitutes the Statement of Eligibility and Qualification
          (Form T-1) of the Trustee under the Trust Indenture Act; or

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

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

               (x)  neither the issue and sale of the Securities, nor the
          consummation of any other of the transactions herein contemplated nor
          the fulfillment of the terms hereof or of any Delayed Delivery
          Contracts will (A) violate the charter or by-laws of the Company or
          the Guarantor, or (B) violate, result in a breach of, or constitute a
          default under the terms of any material indenture or other material
          agreement or instrument known to such counsel and to which the
          Company, the Guarantor or PNC Bank, N.A. is a party or bound, or (C)
          violate


<PAGE>   15
                                     - 15 -




          any material order or regulation known to such counsel to be
          applicable to the Company, the Guarantor or PNC Bank, N.A. of any
          court, regulatory body, administrative agency, governmental body or
          arbitrator having jurisdiction over the Company, or the Guarantor or
          PNC Bank, N.A.; and

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

In rendering such opinion, such counsel will opine only as to matters involving
the application of the laws of the Commonwealth of Pennsylvania or the United
States and may rely (A) as to matters involving the application of laws of any
jurisdiction other than the Commonwealth of Pennsylvania or the United States,
to the extent deemed proper and specified in such opinion, upon the opinion of
other counsel of good standing believed to be reliable and who are reasonably
satisfactory to counsel for the Underwriters, except that it will not be
required that such counsel obtain an opinion of New York counsel as to matters
of New York law in order to render such opinion or that such counsel express an
opinion as to matters arising under the laws of any jurisdiction other than the
laws of the Commonwealth of Pennsylvania and matters of federal law arising
under the laws of the United States of America, and (B) as to matters of fact,
to the extent deemed proper, on certificates of responsible officers of the
Corporation and public officials. References to the Final Prospectus in this
paragraph (b) include any supplements thereto at the Closing Date.

          (c) The Representatives shall have received from Cravath, Swaine &
     Moore, counsel for the Underwriters, such opinion or opinions, dated the
     Closing Date, with respect to the issuance and sale of the Securities, any
     Delayed Delivery Contracts, the Registration Statement, the Final
     Prospectus (together with any supplement thereto) and other related
     matters as the Representatives may reasonably require, and the Company
     shall have furnished to such counsel such documents as they reasonably
     request for the purpose of enabling them to pass upon such matters.

          (d)  The Guarantor shall have furnished to the Representatives a
     certificate of the Guarantor,


<PAGE>   16
                                     - 16 -




     signed by the Chairman of the Board, the President, a Vice Chairman of the
     Board or any Executive or Senior Vice President and the principal
     financial or accounting officer of the Guarantor, dated the Closing Date,
     to the effect that the signers of such certificate have carefully examined
     the Registration Statement, the Final Prospectus, any supplement to the
     Final Prospectus and this Agreement and that:

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

               (ii) no stop order suspending the effectiveness of the
          Registration Statement has been issued and no proceedings for that
          purpose have been instituted or, to the Guarantor's knowledge,
          threatened; and

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

          (e) At the Closing Date, Ernst & Young shall have furnished to the
     Representatives a letter or letters (which may refer to letters previously
     delivered to one or more of the Representatives), dated as of the Closing
     Date, in form and substance satisfactory to the Representatives,
     confirming that they are independent accountants within the meaning of the
     Act and the Exchange Act and the respective applicable published rules and
     regulations thereunder and stating in effect that:


<PAGE>   17
                                     - 17 -





               (i) in their opinion the audited consolidated financial
          statements and financial statement schedules included or incorporated
          in the Registration Statement and the Final Prospectus and reported
          on by them comply in form in all material respects with the
          applicable accounting requirements of the Act and the Exchange Act
          and the related published rules and regulations;

               (ii) on the basis of a reading of the latest unaudited
          consolidated financial statements made available by the Guarantor and
          its subsidiaries; carrying out certain specified procedures (but not
          an audit in accordance with generally accepted auditing standards)
          which would not necessarily reveal matters of significance with
          respect to the comments set forth in such letter; a reading of the
          minutes of the meetings of the shareholders and directors of the
          Guarantor and the audit and executive committees thereof and
          inquiries of certain officials of the Guarantor who have
          responsibility for financial and accounting matters of the Guarantor
          and its subsidiaries as to transactions and events subsequent to the
          date of the most recent audited consolidated financial statements in
          or incorporated in the Final Prospectus, nothing came to their
          attention which caused them to believe that: (1) any unaudited
          consolidated financial statements included or incorporated in the
          Registration Statement and the Final Prospectus do not comply in form
          in all material respects with applicable accounting requirements and
          with the published rules and regulations of the Commission with
          respect to the financial statements included or incorporated in
          quarterly reports on Form 10-Q under the Exchange Act; and said
          unaudited consolidated financial statements are not in conformity
          with generally accepted accounting principles applied on a basis
          substantially consistent with that of the audited consolidated
          financial statements included or incorporated in the Registration
          Statement and the Final Prospectus; or (2) with respect to the period
          subsequent to the date of the most recent audited consolidated
          financial


<PAGE>   18
                                     - 18 -




          statements incorporated in the Registration Statement and the Final
          Prospectus, there were, at a specified date not more than five
          business days prior to the date of the letter, any increases in
          borrowed funds of the Guarantor and its subsidiaries or any decreases
          in the capital stock (defined as each of the individual dollar
          amounts of preferred stock, common stock, and capital surplus) of the
          Guarantor or the stockholders' equity of the Guarantor as compared
          with the amounts shown on the most recent consolidated balance sheet
          incorporated in the Registration Statement and the Final Prospectus,
          or for the period from the date of the most recent audited or
          unaudited consolidated financial statements incorporated in the
          Registration Statement and the Final Prospectus to such specified
          date there were any decreases, as compared with the corresponding
          period in the preceding year, in total or per share amounts of
          consolidated net income of the Guarantor or consolidated net interest
          income except in all instances for changes or decreases set forth in
          such letter, in which case the letter shall be accompanied by an
          explanation by the Guarantor as to the significance thereof unless
          said explanation is not deemed necessary by the Representative; and

               (iii) they have performed certain other specified procedures as
          a result of which they determined that certain information of an
          accounting, financial or statistical nature (which is limited to
          accounting, financial or statistical information derived from the
          general accounting records of the Guarantor and its subsidiaries) set
          forth in the Registration Statement and the Final Prospectus,
          including the information included or incorporated in Items 1, 5, 6
          and 7 of the Guarantor's Annual Report on Form 10-K for the most
          recent fiscal year incorporated in the Registration Statement and the
          Final Prospectus, and the information included in the "Management's
          Discussion and Analysis of Financial Condition and Results of
          Operations" included or incorporated in the Guarantor's Quarterly
          Reports on Form 10-Q, incorporated in the Registration Statement and
          Final Prospectus, agrees with the accounting records


<PAGE>   19
                                     - 19 -




          of the Guarantor and its subsidiaries, excluding any questions of
          legal interpretation.

          References to the Final Prospectus in this paragraph (e) include any
supplement thereto at the date of the letter.

          If provided for in Schedule I hereto, at the Execution Time, Ernst &
Young shall have furnished to the Representatives a letter or letters, dated as
of the Execution Time, in form and substance satisfactory to the
Representatives, to the effect set forth above.

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

          (g) Subsequent to the Execution Time, there shall not have been any
     decrease in the ratings of any of the Guarantor's debt securities by
     Moody's Investors Service, Inc., or Standard & Poor's Corporation.

          (h) Prior to the Closing Date, the Company and the Guarantor shall
     have furnished to the Representatives such further information,
     certificates and documents as the Representatives may reasonably request
     in connection with the offering of the Securities.

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


<PAGE>   20
                                     - 20 -





     If any of the conditions specified in this Section 5 shall not have been
fulfilled in all material respects when and as provided in this Agreement, or
if any of the opinions and certificates mentioned above or elsewhere in this
Agreement shall not be in all material respects reasonably satisfactory in form
and substance to the Representatives and counsel for the Underwriters, this
Agreement and all obligations of the Underwriters hereunder may be canceled at,
or at any time prior to, the Closing Date by the Representatives. Notice of
such cancellation shall be given to the Company in writing or by telephone or
telegraph confirmed in writing.

          6.  Reimbursement of Underwriters' Expenses. If the sale of the
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 5 hereof is not satisfied,
because of any termination pursuant to Section 9 hereof or because of any
refusal, inability or failure on the part of the Company or the Guarantor to
perform any agreement herein or comply with any provision hereof other than by
reason of a default by any of the Underwriters, the Company and the Guarantor
will reimburse the Underwriters severally upon demand for all reasonable
out-of-pocket expenses (including reasonable fees and disbursements of counsel)
that shall have been incurred by them in connection with the proposed purchase
and sale of the Securities. In no event shall the Company or the Guarantor be
liable to the Underwriters for loss of anticipated profits from the
transactions contemplated by this Agreement.

          7.  Indemnification and Contribution. (a) The Company and the
Guarantor agree to indemnify and hold harmless each Underwriter and each person
who controls any Underwriter within the meaning of either the Act or the
Exchange Act against any and all losses, claims, damages or liabilities, joint
or several, to which they or any of them may become subject under the Act, the
Exchange Act or other Federal or state statutory law or regulation, at common
law or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon any untrue statement
or alleged untrue statement of a material fact contained in the registration
statement for the registration of the Securities and any related Depositary
Shares as originally filed or in any amendment thereof, or in the Basic
Prospectus, any Preliminary Final Prospectus or the Final Prospectus, or in any
amendment thereof or supplement thereto, or arise out of or are based upon the
omission or


<PAGE>   21
                                     - 21 -




alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, and agrees to
reimburse each such indemnified party, as incurred, for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that (i) the Company and the Guarantor will not be liable in any such case to
the extent that any such loss, claim, damage or liability arises out of or is
based upon any such untrue statement or alleged untrue statement or omission or
alleged omission made therein in reliance upon and in conformity with written
information furnished to the Company and the Guarantor by or on behalf of any
Underwriter through the Representatives specifically for use in connection with
the preparation thereof, or that part of the Registration Statement
constituting the "Statement of Eligibility and Qualification" (Form T-1) of the
Trustee under the Trust Indenture Act, and (ii) such indemnity with respect to
the Basic Prospectus or any Preliminary Final Prospectus shall not inure to the
benefit of any Underwriter (or any person controlling such Underwriter) from
whom the person asserting any such loss, claim, damage or liability purchased
the Securities or any related Depositary Shares which are the subject thereof
if such person did not receive a copy of the Final Prospectus (or the Final
Prospectus as supplemented) excluding documents incorporated therein by
reference at or prior to the confirmation of the sale of such Securities or
Depositary Shares, if any, to such person in any case where such delivery is
required by the Act and the untrue statement or omission of a material fact
contained in the Basic Prospectus or any Preliminary Final Prospectus was
corrected in the Final Prospectus (or the Final Prospectus as supplemented).
This indemnity agreement will be in addition to any liability which the Company
and the Guarantor may otherwise have.

          (b) Each Underwriter severally agrees to indemnify and hold harmless
the Company and the Guarantor, each of their respective directors, each of
their respective officers who signs the Registration Statement, and each person
who controls the Company or the Guarantor within the meaning of either the Act
or the Exchange Act, to the same extent as the foregoing indemnity from the
Company and the Guarantor to each Underwriter, but only with reference to
written information relating to such Underwriter furnished to the Company and
the Guarantor by or on behalf of such Underwriter through the Representatives
specifically for use in the preparation of the documents referred to in


<PAGE>   22
                                     - 22 -




the foregoing indemnity. This indemnity agreement will be in addition to any
liability which any Underwriter may otherwise have. The Company and the
Guarantor acknowledge that the statements set forth in the last paragraph of
the cover page, the first paragraph of the second page and under the heading
"Underwriting" or "Plan of Distribution" and, if Schedule I hereto provides for
sales of Securities pursuant to delayed delivery arrangements, in the last
sentence under the heading "Delayed Delivery Arrangements" in any Preliminary
Final Prospectus or the Final Prospectus constitute the only information
furnished in writing by or on behalf of the several Underwriters for inclusion
in the documents referred to in the foregoing indemnity, and you, as the
Representatives, confirm that such statements are correct.

          (c) Promptly after receipt by an indemnified party under this Section
7 of notice of the commencement of any action, such indemnified party will, if
a claim in respect thereof is to be made against the indemnifying party under
this Section 7, notify the indemnifying party in writing of the commencement
thereof; but the omission so to notify the indemnifying party will not relieve
it from any liability which it may have to any indemnified party otherwise than
under this Section 7. In case any such action is brought against any
indemnified party, and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate therein, and to
the extent that it may elect by written notice delivered to the indemnified
party promptly after receiving the aforesaid notice from such indemnified
party, to assume the defense thereof, with counsel satisfactory to such
indemnified party; provided, however, that if the defendants in any such action
include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, the
indemnified party or parties shall have the right to select separate counsel to
assert such legal defenses and to otherwise participate in the defense of such
action on behalf of such indemnified party or parties. Upon receipt of notice
from the indemnifying party to such indemnified party of its election so to
assume the defense of such action and approval by the indemnified party of such
counsel, the indemnifying party will not be liable to such indemnified party
under this Section 7 for any legal or


<PAGE>   23
                                     - 23 -




other expenses subsequently incurred by such indemnified party in connection
with the defense thereof unless (i) the indemnified party shall have employed
separate counsel in accordance with the proviso to the next preceding sentence
(it being understood, however, that the indemnifying party shall not be liable
for the expenses of more than one separate counsel (plus any local counsel),
approved by the Representatives in the case of paragraph (a) of this Section 7,
representing the indemnified parties under such paragraph (a) who are parties
to such action), (ii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice of commencement of the action or (iii) the
indemnifying party has authorized the employment of counsel for the indemnified
party at the expense of the indemnifying party; and except that, if clause (i)
or (iii) is applicable, such liability shall be only in respect of the counsel
referred to in such clause (i) or (iii).

          (d) In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in paragraph (a) of
this Section 7 is due in accordance with its terms but is for any reason held
by a court to be unavailable from the Company or the Guarantor on grounds of
policy or otherwise, the Company and the Guarantor, on the one hand, and the
Underwriters, on the other hand, shall contribute to the aggregate losses,
claims, damages and liabilities (including legal or other expenses reasonably
incurred in connection with investigating or defending same) to which the
Company, the Guarantor and one or more of the Underwriters may be subject in
such proportion so that the Underwriters are responsible for that portion
represented by the percentage that the underwriting discount bears to the sum
of such discount and the purchase price of the Securities specified in Schedule
I hereto and the Company and the Guarantor are responsible for the balance;
provided, however, that (y) in no case shall any Underwriter (except as may be
provided in any agreement among underwriters relating to the offering of the
Securities) be responsible for any amount in excess of the underwriting
discount applicable to the Securities purchased by such Underwriter hereunder
and (z) no person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Act) shall be entitled to contribution from any person who
was not guilty of such fraudulent misrepresentation. For purposes of this
Section 7, each person who controls an Underwriter within the meaning of


<PAGE>   24
                                     - 24 -




the Act shall have the same rights to contribution as such Underwriter, and
each person who controls the Company within the meaning of either the Act or
the Exchange Act, each officer of the Company and the Guarantor who shall have
signed the Registration Statement and each director of the Company and the
Guarantor shall have the same rights to contribution as the Company and the
Guarantor, subject in each case to clauses (y) and (z) of this paragraph (d).
Any party entitled to contribution will, promptly after receipt of notice of
commencement of any action, suit or proceeding against such party in respect of
which a claim for contribution may be made against another party or parties
under this paragraph (d), notify such party or parties from whom contribution
may be sought, but the omission to so notify such party or parties shall not
relieve the party or parties from whom contribution may be sought from any
other obligation it or they may have hereunder or otherwise than under this
paragraph (d).

          8.  Default by an Underwriter. If any one or more Underwriters shall
fail to purchase and pay for any of the Securities agreed to be purchased by
such Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Underwriters shall be obligated severally to take up
and pay for (in the respective proportions which the amount of Securities set
forth opposite their names in Schedule II hereto bears to the aggregate amount
of Securities set forth opposite the names of all the remaining Underwriters)
the Securities which the defaulting Underwriter or Underwriters agreed but
failed to purchase; provided, however, that in the event that the aggregate
amount of Securities which the defaulting Underwriter or Underwriters agreed
but failed to purchase shall exceed 10% of the aggregate amount of Securities
set forth in Schedule II hereto, the remaining Underwriters shall have the
right to purchase all, but shall not be under any obligation to purchase any,
of the Securities, and if such non defaulting Underwriters do not purchase all
the Securities, this Agreement will terminate without liability to any non
defaulting Underwriter or the Company or the Guarantor. In the event of a
default by any Underwriter as set forth in this Section 8, the Closing Date
shall be postponed for such period, not exceeding seven days, as the
Representatives shall determine in order that the required changes in the
Registration Statement and the Final Prospectus or in any other documents or
arrangements may be effected.


<PAGE>   25
                                     - 25 -




Nothing contained in this Agreement shall relieve any defaulting Underwriter of
its liability, if any, to the Company and any non defaulting Underwriter for
damages occasioned by its default hereunder.

          9.  Termination. This Agreement shall be subject to termination in
the absolute discretion of the Representatives, by notice given to the Company
and the Guarantor prior to delivery of and payment for the Securities, if prior
to such time (i) trading in the Guarantor's Common Stock shall have been
suspended by the Commission or the New York Stock Exchange or trading in
securities generally on the New York Stock Exchange shall have been suspended
or limited or minimum prices shall have been established on such Exchange, (ii)
a banking moratorium shall have been declared either by Federal, New York State
or Pennsylvania authorities or (iii) there shall have occurred any outbreak or
escalation of hostilities, declaration by the United States of a national
emergency or war or other calamity or crisis the effect of which on financial
markets is such as to make it, in the judgment of the Representatives,
impracticable to market the Securities.

          10.  Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of
the Company, the Guarantor or their respective officers and of the Underwriters
set forth in or made pursuant to this Agreement will remain in full force and
effect, regardless of any investigation made by or on behalf of any Underwriter
or the Company or the Guarantor or any of the officers, directors or
controlling persons referred to in Section 7 hereof, and will survive delivery
of and payment for the Securities. The provisions of Sections 6 and 7 hereof
shall survive the termination or cancellation of this Agreement.

          11.  Notices. All communications hereunder will be in writing and
effective only on receipt, and, if sent to the Representatives, will be mailed,
delivered or transmitted by any standard form of telecommunication, at the
address specified in Schedule I hereto; or, if sent to the Company or the
Guarantor, will be mailed, delivered or transmitted by any standard form of
telecommunication to it at One PNC Plaza, 249 Fifth Avenue, Pittsburgh,
Pennsylvania 15222, attention of the Senior Vice President and Chief Financial
Officer of the Guarantor.

          12.  Successors. This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the
officers and directors and controlling persons referred to in Section 7 hereof,
and no other person will have any right or obligation hereunder.

          13.  Applicable Law.  This Agreement will be governed by and
construed in accordance with the laws of the State of New York.

                                        [date]

To the Representatives
  named in Schedule I
  hereto of the
  Underwriters named in
  Schedule II hereto

Dear Sirs:

          PNC Bank Corp., a Pennsylvania corporation (the "Corporation"),
proposes to sell to the underwriters named in Schedule II hereto (the
"Underwriters"), for whom you are acting as representatives (the
"Representatives"), the number of shares of preferred stock and/or common stock
of the Corporation identified in Schedule I hereto (said shares to be issued
and sold by the Corporation being hereinafter called the "Underwritten
Securities").  The Corporation also proposes to grant to the Underwriters an
option to purchase up to such additional number of shares of preferred stock
and/or common stock of the Corporation as is specified in Schedule I hereto
(the "Option Securities"; together with the Underwritten Securities, the
"Securities") to cover over-allotments. If "Depositary Receipt Arrangements" is
specified in Schedule I hereto, the Securities are to be deposited by you or on
your behalf against delivery of Depositary Receipts (the "Depositary Receipts")
to be issued by the bank or trust company identified in Schedule I hereto as
Depositary (the "Depositary"), under the deposit agreement described in
Schedule I hereto (the "Deposit Agreement"), among the Corporation, the
Depositary and the holders from time to time of the Depositary Receipts issued
thereunder. Any Depositary Receipts will


<PAGE>   2
                                     - 2 -





evidence Depositary Shares (the "Depositary Shares") and each Depositary Share
will represent a fraction of a Security, as specified in Schedule I hereto.
Except where the context otherwise requires, references to Securities herein
shall include any related Depositary Shares and associated Depositary Receipts.
If the firm or firms listed in Schedule II hereto include only the firm or
firms listed in Schedule I hereto, then the terms "Underwriters" and
"Representatives," as used herein, shall each be deemed to refer to such firm
or firms.

          1.  Representations and Warranties. The Corporation represents and
warrants to, and agrees with, each Underwriter as set forth below in this
Section 1. Certain terms used in this Section 1 are defined in paragraph (c)
hereof.

          (a) If the offering of the Securities is a Delayed Offering (as
     specified in Schedule I hereto), paragraph (i) below is applicable and, if
     the offering of the Securities is a Non-Delayed Offering (as so
     specified), paragraph (ii) below is applicable.

               (i)  The Corporation meets the requirements for the use of Form
          S-3 under the Securities Act of 1933 (the "Act") and has filed with
          the Securities and Exchange Commission (the "Commission") a
          registration statement (the file number of which is set forth in
          Schedule I hereto), on such Form, including a basic prospectus, for
          registration under the Act of the offering and sale of the
          Securities.  The Corporation may have filed one or more amendments
          thereto, and may have used a Preliminary Final Prospectus, each of
          which has previously been furnished to you. Such registration
          statement, as so amended, has become effective. The offering of the
          Securities is a Delayed Offering and, accordingly, it is not
          necessary that any further information with respect to the Securities
          and the offering thereof required by the Act and the rules thereunder
          to be included in the Final Prospectus have been included in an
          amendment to such registration statement prior to the Effective Date.
          The Corporation will next file with the Commission pursuant to Rules
          415 and 424(b)(2) or (5) a final supplement to the form of prospectus


<PAGE>   3
                                     - 3 -




          included in such registration statement relating to the Securities
          and the offering thereof. As filed, such final prospectus supplement
          shall include all required information with respect to the Securities
          and the offering thereof and, except to the extent the
          Representatives shall agree in writing to a modification, shall be in
          all substantive respects in the form furnished to you prior to the
          Execution Time or, to the extent not completed at the Execution Time,
          shall contain only such specific additional information and other
          changes (beyond that contained in the Basic Prospectus and any
          Preliminary Final Prospectus) as the Corporation has advised you,
          prior to the Execution Time, will be included or made therein.

               (ii)  The Corporation meets the requirements for the use of Form
          S-3 under the Act and has filed with the Commission a registration
          statement (the file number of which is set forth in Schedule I
          hereto) on such Form, including a basic prospectus, for registration
          under the Act of the offering and sale of the Securities. The
          Corporation may have filed one or more amendments thereto, including
          a Preliminary Final Prospectus, each of which has previously been
          furnished to you.  The Corporation will next file with the Commission
          either (x) a final prospectus supplement relating to the Securities
          in accordance with Rules 430A and 424(b)(1) or (4), or (y) prior to
          the effectiveness of such registration statement, an amendment to
          such registration statement, including the form of final prospectus
          supplement. In the case of clause (x), the Corporation included in
          such registration statement, as amended at the Effective Date, all
          information (other than Rule 430A Information) required by the Act
          and the rules thereunder to be included in the Final Prospectus with
          respect to the Securities and the offering thereof. As filed, such
          final prospectus supplement or such amendment and form of final
          prospectus supplement shall contain all Rule 430A Information,
          together with all other such required information, with respect to
          the Securities and the offering thereof and, except to the extent the
          Representatives shall


<PAGE>   4
                                     - 4 -




          agree in writing to a modification, shall be in all substantive
          respects in the form furnished to you prior to the Execution Time or,
          to the extent not completed at the Execution Time, shall contain only
          such specific additional information and other changes (beyond that
          contained in the Basic Prospectus and any Preliminary Final
          Prospectus) as the Corporation has advised you, prior to the
          Execution Time, will be included or made therein.

          (b) On the Effective Date, the Registration Statement did or will,
     and when the Final Prospectus is first filed (if required) in accordance
     with Rule 424(b) and on the Closing Date, the Final Prospectus (and any
     supplement thereto) will, comply in all material respects with the
     applicable requirements of the Act and the Securities Exchange Act of 1934
     (the "Exchange Act") and the respective rules thereunder; on the Effective
     Date, the Registration Statement did not or will not contain any untrue
     statement of a material fact or omit to state any material fact required
     to be stated therein or necessary in order to make the statements therein
     not misleading; and, on the Effective Date, the Final Prospectus, if not
     filed pursuant to Rule 424(b), did not or will not, and on the date of any
     filing pursuant to Rule 424(b) and on the Closing Date, the Final
     Prospectus (together with any supplement thereto) will not, include any
     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 Corporation makes no representations or warranties as to
     (i) that part of the Registration Statement which shall constitute the
     Statement of Eligibility and Qualification (Form T-1) under the Trust
     Indenture Act of the Trustee or (ii) the information contained in or
     omitted from the Registration Statement or the Final Prospectus (or any
     supplement thereto) in reliance upon and in conformity with information
     furnished in writing to the Corporation by or on behalf of any Underwriter
     through the Representatives specifically for use in connection with the
     preparation of the Registration Statement or the Final Prospectus (or any
     supplement thereto).

                                     - 5 -




          (c) The terms which follow, when used in this Agreement, shall have
     the meanings indicated. The term "the Effective Date" shall mean each date
     that the Registration Statement and any post effective amendment or
     amendments thereto became or become effective. "Execution Time" shall mean
     the date and time that this Agreement is executed and delivered by the
     parties hereto. "Basic Prospectus" shall mean the prospectus referred to
     in paragraph (a) above contained in the Registration Statement at the
     Effective Date including, in the case of a Non-Delayed Offering, any
     Preliminary Final Prospectus. "Preliminary Final Prospectus" shall mean
     any preliminary prospectus supplement to the Basic Prospectus which
     describes the Securities and the offering thereof and is used prior to
     filing of the Final Prospectus. "Final Prospectus" shall mean the
     prospectus supplement relating to the Securities that is first filed
     pursuant to Rule 424(b) after the Execution Time, together with the Basic
     Prospectus or, if, in the case of a Non-Delayed Offering, no filing
     pursuant to Rule 424(b) is required, shall mean the form of final
     prospectus relating to the Securities, including the Basic Prospectus,
     included in the Registration Statement at the Effective Date.
     "Registration Statement" shall mean the registration statement referred to
     in paragraph (a) above, including incorporated documents, exhibits and
     financial statements, as amended at the Execution Time (or, if not
     effective at the Execution Time, in the form in which it shall become
     effective) and, in the event any post effective amendment thereto becomes
     effective prior to the Closing Date (as hereinafter defined), shall also
     mean such registration statement as so amended. Such term shall include
     any Rule 430A Information deemed to be included therein at the Effective
     Date as provided by Rule 430A. "Rule 415," "Rule 424," "Rule 430A" and
     "Regulation S-K" refer to such rules or regulation under the Act. "Rule
     430A Information" means information with respect to the Securities and the
     offering thereof permitted to be omitted from the Registration Statement
     when it becomes effective pursuant to Rule 430A. Any reference herein to
     the Registration Statement, the Basic Prospectus, any Preliminary Final
     Prospectus or the Final Prospectus shall be deemed to refer to and include
     the documents incorporated by reference therein pursuant to Item 12 of
     Form S-3 which were filed


<PAGE>   6
                                     - 6 -


     under the Exchange Act on or before the Effective Date of the Registration
     Statement or the issue date of the Basic Prospectus, any Preliminary Final
     Prospectus or the Final Prospectus, as the case may be; and any reference
     herein to the terms "amend," "amendment" or "supplement" with respect to
     the Registration Statement, the Basic Prospectus, any Preliminary Final
     Prospectus or the Final Prospectus shall be deemed to refer to and include
     the filing of any document under the Exchange Act after the Effective Date
     of the Registration Statement or the issue date of the Basic Prospectus,
     any Preliminary Final Prospectus or the Final Prospectus, as the case may
     be, deemed to be incorporated therein by reference. A "Non-Delayed
     Offering" shall mean an offering of securities which is intended to
     commence promptly after the effective date of a registration statement,
     with the result that, pursuant to Rules 415 and 430A, all information
     (other than Rule 430A Information) with respect to the securities so
     offered must be included in such registration statement at the effective
     date thereof. A "Delayed Offering" shall mean an offering of securities
     pursuant to Rule 415 which does not commence promptly after the effective
     date of a registration statement, with the result that only information
     required pursuant to Rule 415 need be included in such registration
     statement at the effective date thereof with respect to the securities so
     offered. Whether the offering of the Securities is a Non-Delayed Offering
     or a Delayed Offering shall be set forth in Schedule I hereto.

          2.  Purchase and Sale. (a) (i) Subject to the terms and conditions and
in reliance upon the representations and warranties herein set forth, the
Corporation agrees to sell to each Underwriter, and each Underwriter agrees,
severally and not jointly, to purchase from the Corporation, at the purchase
price set forth in Schedule I hereto the number of shares of the Securities set
forth opposite such Underwriter's name in Schedule II hereto, except that, if
Schedule I hereto provides for the sale of Securities pursuant to delayed
delivery arrangements, the respective number of shares of Securities to be
purchased by the Underwriters shall be as set forth in Schedule II hereto less
the respective number of shares of Contract Securities determined as provided
below. Securities to be purchased by the Underwriters are herein sometimes
called the "Underwriters' Securities" and Securities to


<PAGE>   7
                                     - 7 -




be purchased pursuant to Delayed Delivery Contracts as hereinafter provided are
herein called "Contract Securities."

          (a)(ii) If so provided in Schedule I hereto, the Underwriters are
authorized to solicit offers to purchase Securities from the Corporation
pursuant to delayed delivery contracts ("Delayed Delivery Contracts"),
substantially in the form of Schedule III hereto but with such changes therein
as the Corporation may authorize or approve. The Underwriters will endeavor to
make such arrangements and, as compensation therefor, the Corporation will pay
to the Representatives, for the account of the Underwriters, on the Closing
Date, the percentage set forth in Schedule I hereto of the aggregate
liquidation preference of the Securities for which Delayed Delivery Contracts
are made.  Delayed Delivery Contracts are to be with institutional investors,
including commercial and savings banks, insurance companies, pension funds,
investment companies and educational and charitable institutions. The
Corporation will enter into Delayed Delivery Contracts in all cases where sales
of Contract Securities arranged by the Underwriters have been approved by the
Corporation but, except as the Corporation may otherwise agree, each such
Delayed Delivery Contract must be for not less than the minimum number of
shares set forth in Schedule I hereto and the aggregate number of shares of
Contract Securities may not exceed the maximum aggregate number of shares set
forth in Schedule I hereto. The Underwriters will not have any responsibility
in respect of the validity or performance of Delayed Delivery Contracts. The
number of shares of Securities to be purchased by each Underwriter as set forth
in Schedule II hereto shall be reduced by the number of shares which shall bear
the same proportion to the total number of shares of Contract Securities as the
number of shares of Securities set forth opposite the name of such Underwriter
bears to the aggregate number of shares set forth in Schedule II hereto, except
to the extent that you determine that such reduction shall be otherwise than in
such proportion and so advise the Corporation in writing; provided, however,
that the total number of shares of Securities to be purchased by all
Underwriters shall be the aggregate number of shares set forth in Schedule II
hereto less the aggregate number of shares of Contract Securities.

          (b)  Subject to the terms and conditions and in reliance upon the
representations and warranties


<PAGE>   8
                                     - 8 -




herein set forth, the Corporation hereby grants an option to the several
Underwriters to purchase, severally and not jointly, the Option Securities at
the same purchase price per share as the Underwriters shall pay for the
Underwritten Securities. Said option may be exercised only to cover
over-allotments in the sale of the Underwritten Securities by the Underwriters.
Said option may be exercised in whole or in part at any time (but not more than
once) on or before the 30th day after the date of the Final Prospectus upon
written or telegraphic notice by the Representatives to the Corporation setting
forth the number of shares of the Option Securities as to which the several
Underwriters are exercising the option and the settlement date. Delivery of
certificates for the shares of Option Securities, and payment therefor, shall
be made as provided in Section 3 hereof. The number of shares of the Option
Securities to be purchased by each Underwriter shall be the same percentage of
the total number of shares of the Option Securities to be purchased by the
several Underwriters as such Underwriter is purchasing the Underwritten
Securities, subject to such adjustments as you in your absolute discretion
shall make to eliminate any fractional shares.

          3.  Delivery and Payment. Delivery of and payment for the
Underwriters' Securities shall be made on the date and at the time specified in
Schedule I hereto (or such later date not later than five business days after
such specified date as the Representatives shall designate), which date and
time may be postponed by agreement among the Representatives, the Corporation
or as provided in Section 8 hereof (such date and time of delivery and payment
for the Underwriters' Securities being herein called the "Closing Date").
Delivery of the Underwriters' Securities shall be made to the Representatives
for the respective accounts of the several Underwriters against payment by the
several Underwriters through the Representatives of the purchase price thereof
to or upon the order of the Corporation by wire transfer of immediately
available funds. Delivery of the Underwriters' Securities shall be made at such
location in The City of New York as the Representatives shall reasonably
designate at least one business day in advance of the Closing Date and payment
for the Securities shall be made at the office specified in Schedule I hereto.
Certificates for the Underwriters' Securities shall be registered in such names

and transfer) and in such denominations as the Representatives may request not
less than two full business days in advance of the Closing Date.

          The Corporation agrees to have the Underwriters' Securities available
for inspection, checking and packaging by the Representatives in New York, New
York, not later than 1:00 p.m. on the business day prior to the Closing Date.

          If the option provided for in Section 2(b) hereof is exercised after

The City of New York as the Representatives shall reasonably designate, on the
date specified by the Representative (which shall be within three business days
after exercise of said option), certificates for the Option Securities in such
names and denominations as the Representatives shall have requested against
payment of the purchase price thereof to or upon the order of the Corporation
by wire transfer of immediately available funds. If settlement for the Option
Securities occurs after the Closing Date, the Corporation will deliver to the
Representatives on the settlement date for the Option Securities, and the
obligation of the Underwriters to purchase the Option Securities shall be
conditioned upon receipt of, supplemental opinions, certificates and letters
confirming as of such date the opinions, certificates and letters delivered on
the Closing Date pursuant to Section 5 hereof.

          Notwithstanding the preceding paragraphs, if "Depositary Receipt
Arrangements" is specified in Schedule I hereto, certificates representing

          4.  Agreements.  The Corporation agrees with the several Underwriters
that:

          (a) The Corporation will use its best efforts to cause the
     Registration Statement, if not effective at the Execution Time, and any
     amendment thereto, to become effective. Prior to the termination of the
     offering of the Securities, the Corporation will not file any amendment to
     the Registration Statement or supplement (including the Final Prospectus
     or any Preliminary Final Prospectus) to the Basic Prospectus unless the
     Corporation has furnished you a copy for your review prior to filing and
     will not file any such proposed amendment or supplement to which you
     reasonably object. Subject to the foregoing sentence, the Corporation will
     cause the Final Prospectus, properly completed, and any supplement thereto
     to be filed with the Commission pursuant to the applicable paragraph of
     Rule 424(b) within the time period prescribed and will provide evidence
     satisfactory to the Representatives of such timely filing. The Corporation
     will promptly advise the Representatives (i) when the Registration
     Statement, if not effective at the Execution Time, and any amendment
     thereto, shall have become effective, (ii) when the Final Prospectus, and
     any supplement thereto, shall have been filed with the Commission pursuant
     to Rule 424(b), (iii) when, prior to termination of the offering of the
     Securities, any amendment to the Registration Statement shall have been
     filed or become effective, (iv) of any request by the Commission for any
     amendment of the Registration Statement or supplement to the Final
     Prospectus or for any additional information, (v) of the issuance by the
     Commission of any stop order suspending the effectiveness of the
     Registration Statement or the institution or threatening of any proceeding
     for that purpose and (vi) of the receipt by the Corporation of any
     notification with respect to the suspension of the qualification of the
     Securities for sale in any jurisdiction or the initiation or threatening
     of any proceeding for such purpose. The Corporation will use its best
     efforts to prevent the issuance of any such stop order and, if issued, to
     obtain as soon as possible the withdrawal thereof.

          (b)  If, at any time when a prospectus relating to the Securities is
     required to be


<PAGE>   11
                                     - 11 -




     delivered under the Act, any event occurs as a result of which the Final
     Prospectus as then supplemented would include any untrue statement of a
     material fact or omit to state any material fact necessary to make the
     statements therein in the light of the circumstances under which they were
     made not misleading, or if it shall be necessary to amend the Registration
     Statement or supplement the Final Prospectus to comply with the Act or the
     Exchange Act or the respective rules thereunder, the Corporation promptly
     will prepare and file with the Commission, subject to the second sentence
     of paragraph (a) of this Section 4, an amendment or supplement which will
     correct such statement or omission or effect such compliance.

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

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

          (e) The Corporation will use its best efforts to arrange for the
     qualification of the Securities for sale under the laws of such
     jurisdictions as the Representatives may designate, will maintain such
     qualifications in effect so long as required for the distribution of the
     Securities and will arrange for the determination of the legality of the
     Securities for purchase by institutional investors; provided, however,
     that the Corporation shall not be required to qualify to do business in
     any jurisdiction where it is not now qualified or to take any action which
     would subject it to general or unlimited service of process in any
     jurisdiction where they are not now subject.

          (f) Until the date specified on Schedule I hereto, the Corporation
     will not, without the consent of the Representatives, offer, sell or
     contract to sell, or announce the offering of, (i) any shares of preferred
     stock or common stock covered by the Registration Statement or any other
     registration statement filed under the Act, or (ii) if the Securities are
     convertible into other securities of the Corporation, any of such other
     securities, in each case other than shares of common or preferred stock of
     the Corporation issued pursuant to warrants to purchase any such shares,
     issued upon conversion of the Corporation's outstanding convertible
     debentures or issued pursuant to any employee benefit or dividend
     reinvestment plan of the Corporation in effect at the Execution Time.

          5.  Conditions to the Obligations of the Underwriters. The
obligations of the Underwriters to purchase the Underwriters' Securities shall
be subject to the accuracy in all material respects of the representations and
warranties on the part of the Corporation contained herein as of the Execution
Time and the Closing Date, to the accuracy in all material respects of the
statements of the Corporation made in any certificates pursuant to the
provisions hereof, to the performance in all material respects by the
Corporation of its obligations hereunder and to the following additional
conditions:

          (a) If the Registration Statement has not become effective prior to
     the Execution Time, unless the Representatives agree in writing to a later
     time, the Registration Statement will become effective not later than (i)
     6:00 p.m. New York City time, on the date of determination of the public
     offering price, if such determination occurred at or prior to 3:00 p.m.
     New York City time on such date or (ii) 12:00 Noon on the business day
     following the day on which the public offering price was determined, if
     such determination occurred after 3:00 p.m. New York City time on such
     date; if filing of the Final Prospectus, or any supplement thereto, is
     required pursuant to Rule 424(b), the Final Prospectus, and any such
     supplement, shall have been filed in the manner and within the time period
     required by Rule 424(b); and no stop order suspending the effectiveness of
     the Registration Statement shall


<PAGE>   13
                                     - 13 -


     have been issued and no proceedings for that purpose shall have been
     instituted or threatened.

          (b) The Corporation shall have furnished to the Representatives the
     opinion of Melanie S. Cibik, Esq., Senior Counsel of the Corporation,
     dated the Closing Date, to the effect that:

               (i)  the Corporation is a corporation validly organized and
          presently subsisting under the laws of the Commonwealth of
          Pennsylvania with all requisite corporate power and authority to own
          its properties and conduct its business as described in the Final
          Prospectus, except for such power and authority the absence of which
          would not have a material adverse effect on the Corporation, and is
          duly registered as a bank holding company under the Bank Holding
          Company Act of 1956, as amended;

               (ii)  PNC Bank, National Association ("PNC Bank, N.A.") is a
          national banking organization validly existing in good standing under
          the laws of the United States, with all requisite corporate power and
          authority to own, lease and operate its properties and conduct its
          business as described in the Final Prospectus, except for such power
          and authority the absence of which would not have a material adverse
          effect on PNC Bank, N.A.;

               (iii)  all the outstanding shares of capital stock of PNC Bank,
          N.A. have been duly and validly authorized and issued and (except as
          provided in 12 U.S.C. Section 55) are fully paid and nonassessable,
          and, except as otherwise set forth in the Final Prospectus, all
          outstanding shares of capital stock of PNC Bank, N.A. are owned by the
          Corporation either directly or through wholly owned subsidiaries free
          and clear of any perfected security interest and, to the knowledge of
          such counsel, any other security interests, claims, liens or
          encumbrances;

               (iv)  the Corporation's authorized equity capitalization, if set
          forth in the Final Prospectus, is as set forth in the Final
          Prospectus; the Securities and any Depositary Receipts conform in all
          material respects to


<PAGE>   14
                                     - 14 -




          the description thereof contained in the Final Prospectus; the
          Securities have been duly and validly authorized, and, when issued
          and delivered to and paid for by the Underwriters pursuant to this
          Agreement, will be fully paid an nonassessable and, if the Securities
          or related Depositary Shares are to be listed on any stock exchange,
          authorization therefor has been given, subject to official notice of
          issuance and evidence of satisfactory distribution, or the
          Corporation has filed a preliminary listing application and all
          required supporting documents with respect to the Securities or such
          Depositary Shares, if any, with such stock exchange and nothing has
          caused such counsel to believe that the Securities or such Depositary
          Shares, if any, will not be authorized for listing, subject to
          official notice of issuance and evidence of satisfactory
          distribution;

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

               (vi)  the Registration Statement has become effective under the
          Act; any required filing of the Basic Prospectus, any Preliminary
          Final Prospectus and the Final Prospectus, and any supplements
          thereto, pursuant to Rule 424(b) has been made in the manner and
          within the time period required by Rule 424(b); to the best knowledge
          of such counsel, no stop order suspending the


<PAGE>   15
                                     - 15 -




          effectiveness of the Registration Statement has been issued, no
          proceedings for that purpose have been instituted or threatened, and
          the Registration Statement and the Final Prospectus (other than the
          financial statements and other financial and statistical information
          contained or incorporated therein, and that part of the Registration
          Statement which constitutes the Statement of Eligibility and
          Qualification (Form T-1) of the Trustee under the Trust Indenture
          Act, as to which such counsel need express no opinion) comply as to
          form in all material respects with the applicable requirements of
          that Act and the Exchange Act and the respective rules thereunder;
          and nothing has come to the attention of such counsel that has caused
          such counsel to believe that at the Effective Date the Registration
          Statement contained any untrue statement of a material fact or
          omitted to state any material fact required to be stated therein or
          necessary to make the statements therein not misleading or that the
          Final Prospectus includes any untrue statement of a material fact or
          omits to state a material fact necessary to make the statements
          therein, in the light of the circumstances under which they were
          made, not misleading except that such counsel does not express any
          opinion or belief as to the financial statements or schedules or
          other data of a statistical or financial nature included or
          incorporated therein or as to that part of the Registration Statement
          which constitutes the Statement of Eligibility and Qualification
          (Form T-1) of the Trustee under the Trust Indenture Act;

               (vii)  this Agreement and any Delayed Delivery Contracts have
          been duly authorized, executed and delivered by the Corporation and,
          if any Depositary is also a subsidiary, by such Depositary;

               (viii)  no consent, approval, authorization or order of any
          court or governmental agency or body is required for the consummation
          of the transactions contemplated herein or in any Delayed Delivery
          Contracts, except such as have been obtained under the Act and such
          as may be required


<PAGE>   16
                                     - 16 -




          under the blue sky laws of any jurisdiction in connection with the
          purchase and distribution of the Securities by the Underwriters and
          such other approvals (specified in such opinion) as have been
          obtained;

               (ix)  neither the issue and sale of the Securities, nor the
          consummation of any other of the transactions herein contemplated nor
          the fulfillment of the terms hereof or of any Deposit Agreement or
          Delayed Delivery Contracts will (A) violate the charter or by-laws of
          the Corporation, or (B) violate, result in a breach of, or constitute
          a default under the terms of any material indenture or other material
          agreement or instrument known to such counsel and to which the
          Corporation or PNC Bank, N.A. is a party or bound, or (C) violate any
          material order or regulation known to such counsel to be applicable
          to the Corporation or PNC Bank, N.A. of any court, regulatory body,
          administrative agency, governmental body or arbitrator having
          jurisdiction over the Corporation or PNC Bank, N.A.; and

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

In rendering such opinion, such counsel will opine only as to matters involving
the application of the laws of the Commonwealth of Pennsylvania or the United
States and may rely (A) as to matters involving the application of laws of any
jurisdiction other than the Commonwealth of Pennsylvania or the United States,
to the extent deemed proper and specified in such opinion, upon the opinion of
other counsel of good standing believed to be reliable and who are reasonably
satisfactory to counsel for the Underwriters, except that it will not be
required that such counsel obtain an opinion of New York counsel as to matters
of New York law in order to render such opinion or that such counsel express an
opinion as to matters arising under the laws of any jurisdiction other than the
laws of the Commonwealth of Pennsylvania and matters of federal law arising
under the laws of the United States of America, and (B) as to matters of fact,
to the extent deemed proper, on certificates of responsible officers of the
Corporation and public officials. References to the Final Prospectus in this

paragraph (b) include any supplements thereto at the Closing Date.

          (c) The Representatives shall have received from Cravath, Swaine &
     Moore, counsel for the Underwriters, such opinion or opinions, dated the
     Closing Date, with respect to the issuance and sale of the Securities, any
     Delayed Delivery Contracts, the Registration Statement, the Final
     Prospectus (together with any supplement thereto) and other related
     matters as the Representatives may reasonably require, and the Corporation
     shall have furnished to such counsel such documents as they reasonably
     request for the purpose of enabling them to pass upon such matters.

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

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

               (ii) no stop order suspending the effectiveness of the
          Registration Statement has been issued and no proceedings for that
          purpose have been instituted or, to the Corporation's knowledge,
          threatened; and

               (iii) since the date of the most recent financial statements
          included in the Final Prospectus (exclusive of any supplement
          thereto), there has been no material adverse change in the condition
          (financial or other), earnings, business or properties of the

                                     - 18 -




          Corporation and its subsidiaries taken as a whole, whether or not
          arising from transactions in the ordinary course of business, except
          as set forth in or contemplated in the Final Prospectus (exclusive of
          any supplement thereto).

          (e) At the Closing Date, Ernst & Young shall have furnished to the
     Representatives a letter or letters (which may refer to letters previously
     delivered to one or more of the Representatives), dated as of the Closing
     Date, in form and substance satisfactory to the Representatives,
     confirming that they are independent accountants within the meaning of the
     Act and the Exchange Act and the respective applicable published rules and
     regulations thereunder and stating in effect that:

               (i) in their opinion the audited consolidated financial
          statements and financial statement schedules included or incorporated
          in the Registration Statement and the Final Prospectus and reported
          on by them comply in form in all material respects with the
          applicable accounting requirements of the Act and the Exchange Act
          and the related published rules and regulations;

               (ii) on the basis of a reading of the latest unaudited
          consolidated financial statements made available by the Corporation
          and its subsidiaries; carrying out certain specified procedures (but
          not an audit in accordance with generally accepted auditing
          standards) which would not necessarily reveal matters of significance
          with respect to the comments set forth in such letter; a reading of
          the minutes of the meetings of the shareholders and directors of the
          Corporation and the audit and executive committees thereof and
          inquiries of certain officials of the Corporation who have
          responsibility for financial and accounting matters of the
          Corporation and its subsidiaries as to transactions and events
          subsequent to the date of the most recent audited consolidated
          financial statements in or incorporated in the Final Prospectus,
          nothing came to their attention which caused them to believe that:
          (1) any unaudited consolidated financial statements included or
          incorporated in the


<PAGE>   19
                                     - 19 -




          Registration Statement and the Final Prospectus do not comply in form
          in all material respects with applicable accounting requirements and
          with the published rules and regulations of the Commission with
          respect to the financial statements included or incorporated in
          quarterly reports on Form 10-Q under the Exchange Act; and said
          unaudited consolidated financial statements are not in conformity
          with generally accepted accounting principles applied on a basis
          substantially consistent with that of the audited consolidated
          financial statements included or incorporated in the Registration
          Statement and the Final Prospectus; or (2) with respect to the period
          subsequent to the date of the most recent audited consolidated
          financial statements incorporated in the Registration Statement and
          the Final Prospectus, there were, at a specified date not more than
          five business days prior to the date of the letter, any increases in
          borrowed funds of the Corporation and its subsidiaries or any
          decreases in the capital stock (defined as each of the individual
          dollar amounts of preferred stock, common stock and capital surplus)
          of the Corporation or the stockholders' equity of the Corporation as
          compared with the amounts shown on the most recent consolidated
          balance sheet incorporated in the Registration Statement and the
          Final Prospectus, or for the period from the date of the most recent
          audited or unaudited consolidated financial statements incorporated
          in the Registration Statement and the Final Prospectus to such
          specified date there were any decreases, as compared with the
          corresponding period in the preceding year, in total or per share
          amounts of consolidated net income of the Corporation or consolidated
          net interest income except in all instances for changes or decreases
          set forth in such letter, in which case the letter shall be
          accompanied by an explanation by the Corporation as to the
          significance thereof unless said explanation is not deemed necessary
          by the Representative; and

               (iii) they have performed certain other specified procedures as
          a result of which they determined that certain information of an

          accounting, financial or statistical nature (which is limited to
          accounting, financial or statistical information derived from the
          general accounting records of the Corporation and its subsidiaries)
          set forth in the Registration Statement and the Final Prospectus,
          including the information included or incorporated in Items 1, 5, 6
          and 7 of the Corporation's Annual Report on Form 10-K for the most
          recent fiscal year incorporated in the Registration Statement and the
          Final Prospectus, and the information included in the "Management's
          Discussion and Analysis of Financial Condition and Results of
          Operations" included or incorporated in the Corporation's Quarterly
          Reports on Form 10-Q, incorporated in the Registration Statement and
          Final Prospectus, agrees with the accounting records of the
          Corporation and its subsidiaries, excluding any questions of legal
          interpretation.

          References to the Final Prospectus in this paragraph (e) include any
supplement thereto at the date of the letter.

          If provided for in Schedule I hereto, at the Execution Time, Ernst &
Young shall have furnished to the Representatives a letter or letters, dated as
of the Execution Time, in form and substance satisfactory to the
Representatives, to the effect set forth above.

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

          (g) Subsequent to the Execution Time, there shall not have been any
     decrease in the ratings of any of the Corporation's equity securities by
     Moody's Investors Service, Inc., or Standard & Poor's Corporation.

          (h) Prior to the Closing Date, the Corporation shall have furnished
     to the Representatives such further information, certificates and
     documents as the Representatives may reasonably request in connection with
     the offering of the Securities.

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

          (j) Any Deposit Agreement shall have been duly executed by the
     Corporation and the Depositary.

          If any of the conditions specified in this Section 5 shall not have
been fulfilled in all material respects when and as provided in this Agreement,
or if any of the opinions and certificates mentioned above or elsewhere in this
Agreement shall not be in all material respects reasonably satisfactory in form
and substance to the Representatives and counsel for the Underwriters, this
Agreement and all obligations of the Underwriters hereunder may be canceled at,
or at any time prior to, the Closing Date by the Representatives. Notice of
such cancellation shall be given to the Corporation in writing or by telephone
or telegraph confirmed in writing.

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


<PAGE>   22
                                     - 22 -




sale of the Securities. In no event shall the Corporation be liable to the
Underwriters for loss of anticipated profits from the transactions contemplated
by this Agreement.

          7.  Indemnification and Contribution. (a) The Corporation agrees to
indemnify and hold harmless each Underwriter and each person who controls any
Underwriter within the meaning of either the Act or the Exchange Act against
any and all losses, claims, damages or liabilities, joint or several, to which
they or any of them may become subject under the Act, the Exchange Act or other
Federal or state statutory law or regulation, at common law or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in the registration statement for the
registration of the Securities and any related Depositary Shares as originally
filed or in any amendment thereof, or in the Basic Prospectus, any Preliminary
Final Prospectus or the Final Prospectus, or in any amendment thereof or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and agrees to
reimburse each such indemnified party, as incurred, for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that (i) the Corporation will not be liable in any such case to the extent that
any such loss, claim, damage or liability arises out of or is based upon any
such untrue statement or alleged untrue statement or omission or alleged
omission made therein in reliance upon and in conformity with written
information furnished to the Corporation by or on behalf of any Underwriter
through the Representatives specifically for use in connection with the
preparation thereof, or that part of the Registration Statement constituting
the "Statement of Eligibility and Qualification" (Form T-1) of the Trustee
under the Trust Indenture Act, and (ii) such indemnity with respect to the
Basic Prospectus or any Preliminary Final Prospectus shall not inure to the
benefit of any Underwriter (or any person controlling such Underwriter) from
whom the person asserting any such loss, claim, damage or liability purchased
the Securities or any related Depositary Shares which are the subject thereof
if such person did not receive a copy of the Final Prospectus (or the Final
Prospectus as supplemented) excluding documents incorporated therein by
reference at or prior to the


<PAGE>   23
                                     - 23 -




confirmation of the sale of such Securities or Depositary Shares, if any, to
such person in any case where such delivery is required by the Act and the
untrue statement or omission of a material fact contained in the Basic
Prospectus or any Preliminary Final Prospectus was corrected in the Final
Prospectus (or the Final Prospectus as supplemented). This indemnity agreement
will be in addition to any liability which the Corporation may otherwise have.

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

          (c) Promptly after receipt by an indemnified party under this Section
7 of notice of the commencement of any action, such indemnified party will, if
a claim in respect thereof is to be made against the indemnifying party under
this Section 7, notify the indemnifying party in writing of the commencement
thereof; but the omission so to notify the indemnifying party will not relieve
it from any liability which it may have to any indemnified party otherwise than
under this Section 7. In case any such action is brought against any
indemnified party, and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate


<PAGE>   24
                                     - 24 -




therein, and to the extent that it may elect by written notice delivered to the
indemnified party promptly after receiving the aforesaid notice from such
indemnified party, to assume the defense thereof, with counsel satisfactory to
such indemnified party; provided, however, that if the defendants in any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, the
indemnified party or parties shall have the right to select separate counsel to
assert such legal defenses and to otherwise participate in the defense of such
action on behalf of such indemnified party or parties. Upon receipt of notice
from the indemnifying party to such indemnified party of its election so to
assume the defense of such action and approval by the indemnified party of such
counsel, the indemnifying party will not be liable to such indemnified party
under this Section 7 for any legal or other expenses subsequently incurred by
such indemnified party in connection with the defense thereof unless (i) the
indemnified party shall have employed separate counsel in accordance with the
proviso to the next preceding sentence (it being understood, however, that the
indemnifying party shall not be liable for the expenses of more than one
separate counsel (plus any local counsel), approved by the Representatives in
the case of paragraph (a) of this Section 7, representing the indemnified
parties under such paragraph (a) who are parties to such action), (ii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of commencement of the action or (iii) the indemnifying party has
authorized the employment of counsel for the indemnified party at the expense
of the indemnifying party; and except that, if clause (i) or (iii) is
applicable, such liability shall be only in respect of the counsel referred to
in such clause (i) or (iii).

          (d) In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in paragraph (a) of
this Section 7 is due in accordance with its terms but is for any reason held
by a court to be unavailable from the Corporation on grounds of policy or
otherwise, the Corporation, on the one hand, and the Underwriters, on the other
hand, shall contribute to the aggregate losses, claims, damages and liabilities
(including legal


<PAGE>   25
                                     - 25 -




or other expenses reasonably incurred in connection with investigating or
defending same) to which the Corporation and one or more of the Underwriters
may be subject in such proportion so that the Underwriters are responsible for
that portion represented by the percentage that the underwriting discount bears
to the sum of such discount and the purchase price of the Securities specified
in Schedule I hereto and the Corporation is responsible for the balance;
provided, however, that (y) in no case shall any Underwriter (except as may be
provided in any agreement among underwriters relating to the offering of the
Securities) be responsible for any amount in excess of the underwriting
discount applicable to the Securities purchased by such Underwriter hereunder
and (z) no person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Act) shall be entitled to contribution from any person who
was not guilty of such fraudulent misrepresentation. For purposes of this
Section 7, each person who controls an Underwriter within the meaning of the
Act shall have the same rights to contribution as such Underwriter, and each
person who controls the Corporation within the meaning of either the Act or the
Exchange Act, each officer of the Corporation who shall have signed the
Registration Statement and each director of the Corporation shall have the same
rights to contribution as the Corporation, subject in each case to clauses (y)
and (z) of this paragraph (d). Any party entitled to contribution will,
promptly after receipt of notice of commencement of any action, suit or
proceeding against such party in respect of which a claim for contribution may
be made against another party or parties under this paragraph (d), notify such
party or parties from whom contribution may be sought, but the omission to so
notify such party or parties shall not relieve the party or parties from whom
contribution may be sought from any other obligation it or they may have
hereunder or otherwise than under this paragraph (d).

          8.  Default by an Underwriter. If any one or more Underwriters shall
fail to purchase and pay for any of the Securities agreed to be purchased by
such Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Underwriters shall be obligated severally to take up
and pay for (in the respective proportions which the amount of Securities set
forth opposite their names in Schedule II hereto bears to the aggregate amount
of Securities set forth opposite


<PAGE>   26
                                     - 26 -




the names of all the remaining Underwriters) the Securities which the
defaulting Underwriter or Underwriters agreed but failed to purchase; provided,
however, that in the event that the aggregate amount of Securities which the
defaulting Underwriter or Underwriters agreed but failed to purchase shall
exceed 10% of the aggregate amount of Securities set forth in Schedule II
hereto, the remaining Underwriters shall have the right to purchase all, but
shall not be under any obligation to purchase any, of the Securities, and if
such non defaulting Underwriters do not purchase all the Securities, this
Agreement will terminate without liability to any non defaulting Underwriter or
the Corporation. In the event of a default by any Underwriter as set forth in
this Section 8, the Closing Date shall be postponed for such period, not
exceeding seven days, as the Representatives shall determine in order that the
required changes in the Registration Statement and the Final Prospectus or in
any other documents or arrangements may be effected. Nothing contained in this
Agreement shall relieve any defaulting Underwriter of its liability, if any, to
the Corporation and any non defaulting Underwriter for damages occasioned by
its default hereunder.

          9.  Termination. This Agreement shall be subject to termination in
the absolute discretion of the Representatives, by notice given to the
Corporation prior to delivery of and payment for the Securities, if prior to
such time (i) trading in the Corporation's Common Stock shall have been
suspended by the Commission or the New York Stock Exchange or trading in
securities generally on the New York Stock Exchange shall have been suspended
or limited or minimum prices shall have been established on such Exchange, (ii)
a banking moratorium shall have been declared either by Federal, New York State
or Pennsylvania authorities or (iii) there shall have occurred any outbreak or
escalation of hostilities, declaration by the United States of a national
emergency or war or other calamity or crisis the effect of which on financial
markets is such as to make it, in the judgment of the Representatives,
impracticable to market the Securities.

          10.  Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of
the Corporation or its respective officers and of the Underwriters set forth in
or made pursuant to this Agreement will remain in full force and effect,
regardless of any investigation made by or on behalf of


<PAGE>   27
                                     - 27 -




any Underwriter or the Corporation or any of the officers, directors or
controlling persons referred to in Section 7 hereof, and will survive delivery
of and payment for the Securities. The provisions of Sections 6 and 7 hereof
shall survive the termination or cancellation of this Agreement.

          11.  Notices. All communications hereunder will be in writing and
effective only on receipt, and, if sent to the Representatives, will be mailed,
delivered or transmitted by any standard form of telecommunication, at the
address specified in Schedule I hereto; or, if sent to the Corporation, will be
mailed, delivered or transmitted by any standard form of telecommunication to
it at One PNC Plaza, 249 Fifth Avenue, Pittsburgh, Pennsylvania 15222,
attention of the Senior Vice President and Chief Financial Officer of the
Corporation.

          12.  Successors. This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the
officers and directors and controlling persons referred to in Section 7 hereof,
and no other person will have any right or obligation hereunder.

          13.  Applicable Law.  This Agreement will be governed by and
construed in accordance with the laws of the State of New York.

                                     - 2 -
<PAGE>   8

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

         Receipts shall be executed by the Depositary by the manual signature
of a duly authorized officer of the Depositary; provided, however, that such
signature may be a facsimile if a Registrar for the Receipts (other than the
Depositary) shall have been appointed and such Receipts are countersigned by
manual signature of a duly authorized officer of the Registrar. No Receipt
shall be entitled to any benefits under this Agreement or be valid or
obligatory for any purpose unless it shall have been executed manually by a
duly authorized officer of the Depositary or, if a Registrar for the Receipts
(other than the Depositary) shall have been appointed, by manual or facsimile
signature of a duly authorized officer of the Depositary and countersigned
manually by a duly authorized officer of such Registrar. The Depositary shall
record on its books each Receipt so signed and delivered as hereinafter
provided.

         Except as the Depositary may otherwise determine, Receipts shall be in
denominations of any number of whole Depositary Shares.

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

         Title to Depositary Shares evidenced by a Receipt that is properly
endorsed, or accompanied by a properly executed instrument of transfer, shall
be transferable by delivery with the same effect as in the case of a negotiable
instrument; provided, however, that until transfer of a Receipt shall be
registered on the books of the Depositary as provided in Section 2.04, the
Depositary may, notwithstanding any notice to the contrary, treat the record
holder thereof at such


                                     - 3 -
<PAGE>   9

time as the absolute owner thereof for the purpose of determining the person
entitled to distributions of dividends or other distributions or to any notice
provided for in this Agreement and for all other purposes.

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

         Upon receipt by the Depositary of a certificate or certificates for
the shares of Preferred Stock deposited in accordance with the provisions of
this Section, together with the other documents required, and upon registration
of such shares of Preferred Stock on the books of the Company in the name of
the Depositary or its nominee, the Depositary, subject to the terms and
conditions of this Agreement, shall execute and deliver, to or upon the order
of the person or persons named in the written order delivered to the Depositary
referred to in the first paragraph of this Section, a Receipt or Receipts for
the number of Depositary Shares representing such shares of Preferred Stock and
registered in such name or names as may be requested by such person or persons.

         Certificates in the name of the Depositary for the deposited shares of
Preferred Stock shall be held by the Depositary at the Depositary's Office or
at such other place or places as the Depositary shall determine.

         The Depositary shall execute and deliver such Receipt or Receipts at
the Depositary's Office or such other offices, if any, as the Depositary may



                                     - 4 -
<PAGE>   10

designate. Delivery at other offices shall be at the risk and expense of the
person requesting such delivery.

         Other than in the case of splits, combinations or other
reclassifications affecting the Preferred Stock, or in the case of dividends or
other distributions of Preferred Stock, if any, there shall be deposited
hereunder not more than [NUMBER] shares of Preferred Stock.

         SECTION 2.03. Redemption of Preferred Stock. Whenever the Company
shall elect to redeem shares of Preferred Stock deposited hereunder in
accordance with the provisions of the Certificate, if the Certificate provides
for such redemption, it shall (unless otherwise agreed in writing with the
Depositary) give the Depositary not less than 40 nor more than 70 days' notice
of the date of such proposed redemption of the Preferred Stock, which notice
shall be accompanied by a certificate from the Company stating that such
redemption of the Preferred Stock is in accordance with the provisions of the
Certificate.  Such notice, if given more than 60 days prior to the redemption
date, shall be in addition to the notice required to be given for redemption
pursuant to the Certificate. On the date of such redemption, provided that the
Company shall then have paid in full to the Depositary the redemption price of
any deposited shares of Preferred Stock to be redeemed, plus any accrued and
unpaid dividends thereon, the Depositary shall redeem the number of Depositary
Shares representing such shares of Preferred Stock. The Depositary shall mail
notice of such redemption and the proposed simultaneous redemption of the
number of Depositary Shares representing the deposited shares of Preferred
Stock to be redeemed, first-class postage prepaid, not less than 30 and not
more than 60 days prior to the date fixed for redemption of such Preferred
Stock and Depositary Shares (the "Redemption Date"), to the record holders of
the Receipts evidencing the Depositary Shares to be so redeemed, at the
addresses of such holders as they appear on the records of the Depositary; but
neither failure to mail any such notice to one or more such holders nor any
defect in any notice to one or more such holders shall affect the sufficiency
of the proceedings for redemption as to other holders. Each such notice shall
state: (i) the Redemption Date; (ii) the number of Depositary Shares to be
redeemed and, if less than all the Depository Shares held by any such holder
are to be redeemed, the number of such



                                     - 5 -
<PAGE>   11

Depositary Shares held by such holder to be so redeemed; (iii) the redemption
price; (iv) the place or places where Receipts evidencing Depositary Shares are
to be surrendered for payment of the redemption price; and (v) that dividends
in respect of the shares of Preferred Stock represented by the Depositary
Shares to be redeemed will cease to accumulate and that conversion rights, if
any, in respect thereof will terminate at the close of business on such
Redemption Date. In case less than all the outstanding Depositary Shares are to
be redeemed, the Depositary Shares to be so redeemed shall be selected by lot
or pro rata as may be determined by the Depositary to be equitable.

         Notice having been mailed by the Depositary as aforesaid, from and
after the Redemption Date (unless the Company shall have failed to redeem the
deposited shares of Preferred Stock to be redeemed by it as set forth in the
Company's notice provided for in the preceding paragraph) all dividends in
respect of the deposited shares of Preferred Stock so called for redemption
shall cease to accumulate, the Depositary Shares being redeemed from such
proceeds shall be deemed no longer to be outstanding, all rights of the holders
of Receipts evidencing such Depositary Shares (except the right to receive the
redemption price) shall, to the extent of such Depositary Shares cease and
terminate and, upon surrender in accordance with such notice of the Receipts
evidencing any such Depositary Shares (properly endorsed or assigned for
transfer, if the Depositary shall so require), such Depositary Shares shall be
redeemed by the Depositary at a redemption price per Depositary Share equal to
[SPECIFY FRACTION] of the redemption price per share paid in respect of the
redeemed deposited shares of Preferred Stock plus all money and other property,
if any, represented by such Depositary Shares, including all amounts paid by
the Company in respect of dividends which on the Redemption Date have
accumulated on the shares of Preferred Stock to be so redeemed and have not
theretofore been paid.

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



                                     - 6 -
<PAGE>   12

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

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

         Any holder of a Receipt or Receipts representing a whole number of
deposited shares of Preferred Stock may withdraw such shares of Preferred Stock
and all money and other property, if any, represented thereby by surrendering
such Receipt or Receipts at the Depositary's Office or at such other offices as
the Depositary may designate for such withdrawals. Thereafter, without
unreasonable delay, the Depositary shall deliver to such holder, or to the
person or persons designated by such holder as hereinafter provided the number
of shares of Preferred Stock and all money and other property, if any,
represented by the Receipt or Receipts so surrendered for withdrawal, but
holders of such shares of Preferred Stock will not thereafter be entitled to
deposit such shares of Preferred Stock hereunder or to receive Depositary
Shares therefor. If a Receipt delivered by the holder to the Depositary in
connection with such withdrawal shall evidence a number of Depositary Shares in
excess of the number of deposited Depositary Shares representing the number of
shares of Preferred Stock to be so withdrawn, the Depositary shall at the same
time, in addition to such number of shares of Preferred Stock and such money
and other property, if any, to be so withdrawn,


                                     - 7 -
<PAGE>   13

deliver to such holder, or (subject to Section 2.03) upon his order, a new
Receipt evidencing such excess number of Depositary Shares. Delivery of the
shares of Preferred Stock and money and other property being withdrawn may be
made by the delivery of such certificates, documents of title and other
instruments as the Depositary may deem appropriate.

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

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

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



                                     - 8 -
<PAGE>   14

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

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

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

         [SECTION 2.09. Conversion of Preferred Stock. The Company hereby
agrees to accept the delivery of Receipts for purposes of effecting conversions
of the Preferred Stock utilizing the same procedures as those provided for
delivery of certificates for the Preferred Stock to effect such conversions in
accordance with the terms and conditions of the Preferred Stock as provided in
the Certificate. If the Depositary Shares represented by a Receipt are to be
converted in part only, a new Receipt or Receipts will be issued by the
Depositary for the Depositary Shares not to be converted. For this purpose, a
holder of a Receipt or Receipts must surrender such Receipt or Receipts to the
Company, in care of the Depositary at its Office together with a duly completed
and executed notice


                                     - 9 -
<PAGE>   15

of conversion. In all cases the foregoing shall be conditioned upon compliance
in full by the holders with the terms and conditions of the Preferred Stock as
provided in the Certificate and of this Deposit Agreement. The Company and the
Depositary will thereafter effect the cancellation of each Receipt surrendered
for such conversion and of the related Preferred Stock so converted and any
certificate(s) therefor.]

                                  ARTICLE III

                         Certain Obligations of Holders
                          of Receipts and the Company

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

         SECTION 3.02. Payment of Taxes or Other Governmental Charges. Holders
of Receipts shall be obligated to make payments to the Depositary of certain
charges and expenses, as provided in Section 5.07. Registration of transfer of
any Receipt or any withdrawal of shares of Preferred Stock and all money or
other property, if any, represented by the Depositary Shares evidenced by such
Receipt may be refused until any such payment due is made, and any dividends,
interest payments or other distributions may be withheld or any part of or all
the shares of Preferred Stock or other property represented by the Depositary
Shares evidenced by such Receipt and not theretofore sold may be sold for the
account of the holder thereof (after attempting by reasonable means


                                     - 10 -
<PAGE>   16

to notify such holder prior to such sale), and such dividends, interest
payments or other distributions or the proceeds of any such sale may be applied
to any payment of such charges or expenses, the holder of such Receipt
remaining liable for any deficiency.

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

         [SECTION 3.04. Covenants and Warranties as to Common Stock. The
Company covenants that it will keep reserved or otherwise available a
sufficient number of authorized and unissued shares of Common Stock to meet
conversion requirements in respect of the Preferred Stock and that it will give
written notice to the Depositary of any adjustments in the conversion price as
set forth in the Certificate. The Company represents and warrants that the
Common Stock issued upon conversion of Preferred Stock will be validly issued,
fully paid and nonassessable.]

                                   ARTICLE IV

                       The Deposited Securities; Notices

         SECTION 4.01. Cash Distributions. Whenever the Depositary shall
receive any cash dividend or other cash distribution on deposited shares of
Preferred Stock, the Depositary shall, subject to Sections 3.01 and 3.02,
distribute to record holders of Receipts on the record date fixed pursuant to
Section 4.04 such amounts of such dividend or distribution as are, as nearly as
practicable, in proportion to the respective numbers of Depositary Shares
evidenced by the Receipts held by such holders; provided, however, that in case
the Company or the Depositary shall be required to withhold and shall withhold
from any cash dividend or other cash distribution in respect of the Preferred
Stock an amount on account of taxes, the amount made available for distribution
or distributed in respect of Depositary Shares shall be reduced accordingly.
The Depositary shall distribute or make available for distribution, as the case
may be,


                                     - 11 -
<PAGE>   17

only such amount, however, as can be distributed without attributing to any
holder of Depositary Shares a fraction of one cent, and any balance not so
distributable shall be held by the Depositary (without liability for interest
thereon) and shall be added to and be treated as part of the next sum received
by the Depositary for distribution to record holders of Receipts then
outstanding.

         SECTION 4.02. Distributions Other than Cash, Rights, Preferences or
Privileges. Whenever the Depositary shall receive any distribution other than
cash, rights, preferences or privileges upon deposited shares of Preferred
Stock, the Depositary shall, subject to Sections 3.01 and 3.02, distribute to
record holders of Receipts on the record date fixed pursuant to Section 4.04
such amounts of the securities or property received by it as are, as nearly as
practicable, in proportion to the respective numbers of Depositary Shares
evidenced by the Receipts held by such holders, in any manner that the Receipts
held by such holders, in any manner that the Depositary may deem equitable and
practicable for accomplishing such distribution. If in the opinion of the
Depositary such distribution cannot be made proportionately among such record
holders, or if for any other reason (including any requirement that the Company
or the Depositary withhold an amount on account of taxes) the Depositary deems,
after consultation with the Company, such distribution not to be feasible, the
Depositary may, with the approval of the Company, adopt such method as it deems
equitable and practicable for the purpose of effecting such distribution,
including the sale (at public or private sale) of the securities or property
thus received, or any part thereof, at such place or places and upon such terms
as it may deem proper. The net proceeds of any such sale shall, subject to
Sections 3.01 and 3.02, be distributed or made available for distribution, as
the case may be, by the Depositary to record holders of Receipts as provided by
Section 4.01 in the case of a distribution received in cash. The Company shall
not make any distribution of such securities unless the Company shall have
provided an opinion of counsel stating that such securities have been
registered under the Securities Act of 1933 or do not need to be registered.

         SECTION 4.03. Subscription Rights, Preferences or Privileges. If the
Company shall at any time offer or cause to be offered to the persons in whose
names the shares of Preferred Stock are recorded on the books of the Company


                                     - 12 -
<PAGE>   18

any rights, preferences or privileges to subscribe for or to purchase any
securities or any rights, preferences or privileges of any other nature, such
rights, preferences or privileges shall in each such instance be made available
by the Depositary to the record holders of Receipts in such manner as the
Depositary may determine, either by the issue to such record holders of
warrants representing such rights, preferences or privileges or by such other
method as may be approved by the Depositary in its discretion with the approval
of the Company; provided, however, that (i) if at the time of issue or offer of
any such rights, preferences or privileges the Depositary determines that it is
not lawful or (after consultation with the Company) not feasible to make such
rights, preferences or privileges available to holders of Receipts by the issue
of warrants or otherwise, or (ii) if and to the extent so instructed by holders
of Receipts who do not desire to exercise such rights, preferences or
privileges, then the Depositary, in its discretion (with the approval of the
Company, in any case where the Depositary has determined that it is not
feasible to make such rights, preferences or privileges available), may, if
applicable laws and the terms of such rights, preferences or privileges permit
such transfer, sell such rights, preferences or privileges at public or private
sale, at such place or places and upon such terms as it may deem proper. The
net proceeds of any such sale shall, subject to Sections 3.01 and 3.02, be
distributed by the Depositary to the record holders of Receipts entitled
thereto as provided by Section 4.01 in the case of a distribution received in
cash. The Company shall not make any distribution of any such rights,
preferences or privilege unless the Company shall have provided an opinion of
counsel stating that such rights, preferences or privileges have been
registered under the Securities Act of 1933 or do not need to be registered.

         If registration under the Securities Act of 1933 of the securities to
which any rights, preferences or privileges relate is required in order for
holders of Receipts to be offered or sold the securities to which such rights,
preferences or privileges relate, the Company agrees with the Depositary that
it will file promptly a registration statement pursuant to such Act with
respect to such rights, preferences or privileges and securities and use its
best efforts and take all steps available to it to cause such registration
statement to become effective sufficiently in advance of the expiration of such
rights, preferences or privileges to enable such holders to exercise such
rights, preferences or privileges. In no event shall


                                     - 13 -
<PAGE>   19

the Depositary make available to the holders of Receipts any right, preference
or privilege to subscribe for or to purchase any securities unless and until
such a registration statement shall have become effective, or unless the
offering and sale of such securities to such holders are exempt from
registration under the provisions of such Act.

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

         SECTION 4.04. Notice of Dividends, etc.; Fixing of Record Date for
Holders of Receipts. Whenever any cash dividend or other cash distribution
shall become payable or any distribution other than cash shall be made, or if
rights, preferences or privileges shall at any time be offered, with respect to
the Preferred Stock, or whenever the Depositary shall receive notice of any
meeting at which holders of shares of Preferred Stock are entitled to vote or
of which holders of shares of Preferred Stock are entitled to notice, or
whenever the Depositary and the Company shall decide it is appropriate, the
Depositary shall in each such instance fix a record date (which shall be the
same date as the record date fixed by the Company with respect to the Preferred
Stock) for the determination of the holders of Receipts who shall be entitled
to receive such dividend, distribution, rights, preferences or privileges or
the net proceeds of the sale thereof, or to give instructions for the exercise
of voting rights at any such meeting, or who shall be entitled to notice of
such meeting or for any other appropriate reasons.

         SECTION 4.05. Voting Rights. Upon receipt of notice of any meeting at
which the holders of shares of Preferred Stock are entitled to vote, the
Depositary shall, as soon as practicable thereafter, mail to the record holders
of Receipts a notice which shall contain (i) such information as is contained
in such notice of meeting and (ii) a statement that the holders may, subject to
any



                                     - 14 -
<PAGE>   20

applicable restrictions, instruct the Depositary as to the exercise of the
voting rights pertaining to the number of shares of Preferred Stock represented
by their respective Depositary Shares (including an express indication that
instructions may be given to the Depositary to give a discretionary proxy to a
person designated by the Company) and a brief statement as to the manner in
which such instructions may be given. Upon the written request of the holders
of Receipts on the relevant record date, the Depositary shall endeavor insofar
as practicable to vote or cause to be voted, in accordance with the
instructions set forth in such requests, the maximum whole number of shares of
Preferred Stock represented by the Depositary Shares evidenced by all Receipts
as to which any particular voting instructions are received. The Company hereby
agrees to take all action which may be deemed necessary by the Depositary in
order to enable the Depositary to vote such shares of Preferred Stock or cause
such shares of Preferred Stock to be voted. In the absence of specific
instructions from the holder of a Receipt, the Depositary will abstain from
voting (but, at its discretion, not from appearing at any meeting with respect
to such shares of Preferred Stock unless directed to the contrary by the
holders of all the Receipts) to the extent of the number of shares of Preferred
Stock represented by the Depositary Shares evidenced by such Receipt.

         SECTION 4.06. Changes Affecting Deposited Securities and
Reclassifications, Recapitalizations, etc. Upon any change in par or stated
value, split-up, combination or any other reclassification of the Preferred
Stock, or upon any recapitalization, reorganization, merger, amalgamation or
consolidation affecting the Company or to which it is a party, the Depositary
may in its discretion with the approval of, and shall upon the instructions of,
the Company, and (in either case) in such manner as the Depositary may deem
equitable, (i) make such adjustments as are certified by the Company in (x) the
fraction of any interest represented by one Depositary Share in one share of
Preferred Stock, and (y) the ratio of the redemption price per Depositary Share
to the redemption price per share of Preferred Stock, in each case as may be
necessary fully to reflect the effects of such changes in par or stated value,
split-up, combination or other reclassification of the Preferred Stock, or of
such recapitalization, reorganization, merger, amalgamation or consolidation,
and (ii) treat any securities which shall be received by the Depositary in
exchange for or upon


                                     - 15 -
<PAGE>   21

conversion of or in respect of deposited shares of Preferred Stock as new
deposited securities so received in exchange for or upon conversion or in
respect of such shares of Preferred Stock. In any such case the Depositary may
in its discretion, with the approval of the Company, execute and deliver
additional Receipts, or may call for the surrender of all outstanding Receipts
to be exchanged for new Receipts specifically describing such new deposited
securities. Anything to the contrary herein notwithstanding, holders of
Receipts shall have the right from and after the effective date of any such
changing par or stated value, split-up, combination or other reclassification
of the Preferred Stock or any such recapitalization, reorganization, merger,
amalgamation or consolidation to surrender such Receipts to the Depositary with
instructions to convert, exchange or surrender the shares of Preferred Stock
represented thereby only into or for, as the case may be, the kind and amount
of shares of Preferred Stock and other securities and property and cash into
which the Preferred Stock represented by such Receipts might have been

successor forms), (vi) preparation and filing of state information returns, and

Receipts.

         The Depositary may close such books, at any time or from time to time,
when deemed expedient by it in connection with the performance of its duties
hereunder.

         If the Receipts or the Depositary Shares evidenced thereby or the
Preferred Stock represented by such Depositary Shares shall be listed on the
New York Stock Exchange, the Depositary may, with the approval of the Company,
appoint a Registrar for registration of such Receipts or Depositary Shares in
accordance with any requirements of such Exchange. Such Registrar (which may be
the Depositary if so permitted by the requirements of such Exchange) may be
removed and a substituted registrar appointed by the Depositary upon the
request or with the approval of the Company. If the Receipts, the Depositary
Shares or the Preferred Stock shall be listed on one or more other stock
exchanges, the Depositary will, at the request of the Company, arrange such

liability to any holder of a Receipt if by reason of any provision of any
present or future law, or regulation thereunder, of the United States of
America or of any other governmental authority or, in the case of the
Depositary, the Depositary's Agent or the Registrar, by reason of any
provision, present or future, of the Company's Articles of Incorporation
(including the Certificate) or by reason of any act of God or war or other
circumstance beyond the control of the relevant party, the Depositary, the
Depositary's Agent, the Registrar or the Company shall be prevented or
forbidden from, or subjected to any penalty on account of, doing or performing
any act or thing which the terms of this Agreement provide shall be done or
performed; nor shall the Depositary, any Depositary's Agent, any Registrar or
the Company incur any liability to any



                                     - 18 -
<PAGE>   24

holder of a Receipt (i) by reason of any nonperformance or delay, caused as
aforesaid, in the performance of any act or thing which the terms of this
Deposit Agreement provide shall or may be done or performed or (ii) by reason
of any exercise of, or failure to exercise, any discretion provided for in this

discretion not caused as aforesaid, if caused by the negligence or willful
misconduct of the party charged with such exercise or failure to exercise.

the Registrar and the Company. Neither the Depositary nor any Depositary's
Agent nor any Registrar nor the Company assumes any obligation or shall be
subject to any liability under this Agreement to holders of Receipts other than

nor the Company shall be under any obligation under this Agreement to appear
in, prosecute or defend any action, suit or other proceeding in respect of
deposited shares of Preferred Stock, the Depositary Shares or the Receipts that
in its opinion may involve it in expense or liability unless indemnity
satisfactory to it against all expense and liability be furnished as often as
may be required.

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

         Notwithstanding the first paragraph of this Section, the Depositary
shall not be responsible for any failure to carry out any instruction to vote
any of the deposited shares of Preferred Stock or for the manner or effect of
any such vote made, as long as any such action or nonaction is in good faith or
in accordance

required to undertake, to perform such duties and only such duties as are
specifically set forth in this Deposit Agreement, and no implied covenants or
obligations shall be read into this Deposit Agreement against the Depositary or
any Registrar. The Depositary will indemnify the Company against any liability
that may arise out of acts performed or omitted by the Depositary or its agents
due to its or their negligence or bad faith. The Depositary, the Depositary's
Agents and any Registrar may own and deal in any class of securities of the
Company and its affiliates and Receipts. The Depositary may also act as
transfer agent or registrar of any of the securities of the Company and its
affiliates.

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

         The Depository may at any time be removed by the Company by notice of
such removal delivered to the Depositary, such removal to take effect upon the
appointment of a successor Depositary and its acceptance of such appointment as
hereinafter provided.

         In case at any time the Depositary acting hereunder shall resign or be
removed, the Company shall, within 60 days after the delivery of the notice of
resignation or removal, as the case may be, appoint a successor Depositary,
which shall be a bank or trust company having its principal office in the
United States of America and having a combined capital and surplus of at least
$50,000,000. If no successor Depositary shall have been so appointed and have
accepted appointment within 60 days after delivery of such notice, the
resigning or removed Depositary may petition any court of competent
jurisdiction for the appointment of a successor Depositary. Every successor
Depositary shall execute and delivery to its predecessor and to the Company an
instrument in writing accepting its appointment hereunder, and thereupon such
successor Depositary, without any further act or deed, shall become fully
vested with all the rights, powers, duties and obligations of its predecessor
and for all purposes shall be the


                                     - 20 -
<PAGE>   26

Depositary under this Agreement, and such predecessor, upon payment of all sums
due it and on the written request of the Company, shall execute and deliver an
instrument transferring to such successor all rights and powers of such
predecessor hereunder, shall duly assign, transfer and deliver all right, title
and interest in the Preferred Stock and any moneys or property held hereunder
to such successor, and shall deliver to such successor a list of the record
holders of all outstanding Receipts. Any successor Depositary shall promptly
mail notice of its appointment to the record holders of Receipts.

         Any corporation into or with which the Depositary may be merged,
consolidated or converted shall be the successor of such Depositary without the
execution or filing of any document or any further act, and notice thereof
shall not be required hereunder. Such successor Depositary may authenticate the
Receipts in the name of the predecessor Depositary or in the name of the
successor Depositary.

         Section 5.05. Corporate Notices and Reports. The Company agrees that
it will transmit to the record holders of Receipts, in each case at the
addresses furnished to it pursuant to Section 4.08, all notices and reports
(including without limitation financial statements) required by law, by the
rules of any national securities exchange upon which the Preferred Stock, the
Depositary Shares or the Receipts are listed or by the Company's Articles of
Incorporation (including the Certificate) to be furnished by the Company to
holders of shares of Preferred Stock. Such transmission will be at the
Company's expense.

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


                                     - 21 -

Preferred Stock pursuant to the provisions hereof. The obligations of the
Company set forth in this Section 5.06 shall survive any succession of any
Depositary, Registrar or Depositary's Agent.

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

                           Amendment and Termination

         SECTION 6.01. Amendment. The form of the Receipts and any provisions
of this Agreement may at any time and from time to time be amended by agreement
between the Company and the Depositary in any respect which they may deem
necessary or desirable; provided, however, that no such amendment (other than
any change in the fees of any Depositary, Registrar or Transfer Agent (as
hereinafter defined), which shall go into effect not sooner than three months
after notice thereof to the holders of the Receipts) that shall materially and



                                     - 22 -
<PAGE>   28

adversely alter the rights of the holders of Receipts shall be effective unless
such amendment shall have been approved by the holders of at least a majority
of the Depositary Shares then outstanding. Every holder of an outstanding
Receipt at the time any such amendment becomes effective shall be deemed, by
continuing to hold such Receipt, to consent and agree to such amendment and to
be bound by this Agreement as amended thereby.

         SECTION 6.02. Termination. This Agreement may be terminated by the
Company or the Depositary only after (i) all outstanding Depositary Shares
shall have been redeemed pursuant to Section 2.03 or (ii) there shall have been
made a final distribution in respect of the Preferred Stock in connection with
any liquidation, dissolution or winding up of the Company and such distribution
shall have been distributed to the holders of Depositary Shares pursuant to
Section 4.01 or Section 4.02, as applicable.

         Upon the termination of this Agreement, the Company shall be
discharged from all obligations under this Deposit Agreement except for its
obligations to the Depositary, any Depositary's Agent and any Registrar under
Sections 5.06 and 5.07. The Depositary's indemnity under Section 5.03 shall 
survive the termination of this Agreement and the resignation or removal of 
such Depositary.

         SECTION 7.01. Counterparts. This Agreement may be executed in any
number of counterparts, and by each of the parties hereto on separate

such request.

Holders. Such instrument or instruments and any such record (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Security Holders signing such instrument or instruments and so
voting at any such meeting. Proof of execution of any such instrument or of a
writing appointing any such agent shall be sufficient for any purpose of this

the Company and the Guarantor, if made in the manner provided in this Section.
With respect to Registered Securities, the Company may set a record date for
purposes of determining the identity of Holders entitled to vote or consent to
any action by vote or consent authorized or permitted under this Indenture,
which record date shall be the later of 10 days prior to the first solicitation
of such consent or the date of the most recent list of Holders furnished to the
Trustee pursuant to Section 8.01 of this Indenture prior to such solicitation.
If a record date is fixed, those persons who were Holders of Securities at such
record date (or their duly designated proxies), and only those persons, shall
be entitled to take such action by vote or consent or to revoke any vote or
consent previously given, whether or not such persons continue to be Holders
after such record date. No such vote or consent shall be valid or effective for
more than 120 days after such record date.

instrument or writing may be proved in any reasonable manner which the Trustee

omitted to be done by the Trustee, the Company or the Guarantor in reliance
thereon, whether or not notation of such action is made upon such Security.

referred to in this Section as it shall deem necessary.

SECTION 1.05.  Notices, etc., to Trustee, Company and Guarantor.

or Act of Security Holders or other document provided or permitted by this
Indenture to be made upon, given or furnished to, or filed with,

                (1) the Trustee by any Security Holder or by the Company or the
        Guarantor shall be sufficient for every purpose hereunder if made,
        given, furnished or filed in writing to or with the Trustee at the
        Principal Corporate Trust Office, and, in respect of Unregistered
        Securities or Coupons, at the Corporate Trust office of the Trustee
        referred to in Section 5.02, or

                (2) the Company or the Guarantor by the Trustee or by any
        Security Holder shall be sufficient for every purpose hereunder (except
        as provided in Section 7.01(a)(3)) if in writing and mailed, first
        class, postage prepaid, to the Company or the Guarantor, as the case
        may be, addressed to it at the address of its principal executive
        office specified in the first paragraph of this Indenture or at any
        other address previously furnished in writing to the Trustee by the
        Company or the Guarantor.

Any request, demand, authorization, direction, notice, consent, waiver or Act
of Security Holders or other document provided or permitted by this Indenture
shall be in the English language, except that any published notice may be in
the official language of the country of publication.

SECTION 1.06.  Notices to Holders; Waiver.

        Where this Indenture provides for notice to Holders of any event, (1)
if any of the Securities affected by such event are Fully Registered
Securities, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing


<PAGE>   27


                                     - 17 -


and mailed by first class mail, postage prepaid, to such Holders as their names
and addresses appear in the Security Register within the time prescribed and
(2) if any of the Securities affected by such event are Unregistered
Securities, or Coupon Securities, such notice shall be sufficiently given
(unless otherwise herein expressly provided) if in writing and mailed by first
class mail, postage prepaid, to such Holders in the manner and the extent
provided in Section 313(c) of the Trust Indenture Act and if published in an
Authorized Newspaper or Newspapers in such city or cities as may be provided
elsewhere in this Indenture or specified as contemplated by Section 3.01 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. 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 on such waiver. In any case where notice to Holders is given
by mail, neither the failure to mail such notice, nor any defect in any notice
so mailed to any particular Holder shall affect the sufficiency of such notice
with respect to other Holders, and any notice which is mailed in the manner
herein provided shall be conclusively presumed to have been duly given. In the
event of suspension of regular mail service or for any other reason it shall be
impracticable to give such notice to Registered Holders by mail, then such a
notification as shall be made to Registered Holders 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 by reason of any other cause it shall be impracticable to publish any notice
to Holders of Unregistered Securities or of Coupons as provided above then said
notification to Holders of Unregistered Securities or of Coupons as shall be
given with the approval of the Trustee shall constitute sufficient notice to

SECTION 1.13.  Governing Law.

        This Indenture, the Securities and the Guarantees shall be governed by
and construed in accordance with the laws of the Commonwealth of Pennsylvania,
except that the rights, duties and liabilities of the Trustee as a trustee and
any rights and immunities limiting such liability shall be governed by the laws
of the state in which the principal office of the Trustee shall be located
without regard to principles of conflicts of laws.

SECTION 1.14.  Moneys of Different Currencies To Be Segregated.

        The Trustee shall segregate all moneys, funds and accounts held by the
Trustee hereunder in one currency from any money, funds or accounts in any
other currencies, notwithstanding any provision herein which would otherwise
permit the Trustee to commingle such amounts.

SECTION 1.15.  Payment To Be in Proper Currency.

        Each reference in any Security, or in the Board Resolution relating
thereto, to any currencies or currency units shall be of the essence. Subject
to Section 3.11, the Company and the Guarantor agree, to the fullest extent
that they may effectively do so under applicable law, that their obligation to
make any payment of principal of (and premium, if any) and interest on any
Security or any Coupon (i) shall not be discharged or satisfied by any tender
by the Company or the Guarantor, or recovery by the Trustee, either pursuant to
any judgment (whether or not entered into in accordance with Section 7.16 or
otherwise) in any currencies or currency units other than the currencies or
currency units then due and payable (the "Required Currency"), except to the
extent that such tender or recovery shall result in the actual receipt, by the
payee, of the full amount of the Required Currency expressed to be payable in
respect of such payments, (ii) shall be enforceable as an alternative or
additional cause of action for the purpose of recovering in the Required
Currency the amount, if any, by which such actual receipt shall fall short of
the full amount of the Required Currency so expressed to be payable and (iii)
shall not be affected by judgment being obtained for any other sum due under
this Indenture. Except as permitted under Section 3.11, if any such tender or
recovery is in a currency other than the Required Currency, the Trustee may
take such actions as it considers appropriate to exchange such currency for the
Required Currency. The costs and risks of any such exchange, including without
limitation the risks of delay and exchange rate fluctuation, shall be borne by
the Company and the Guarantor, and the Company and the Guarantor shall remain
fully liable for any shortfall or delinquency in the full amount of Required
Currency


<PAGE>   30

                                     - 20 -


then due and payable, and in no circumstances shall the Trustee be liable
therefor. The Company and the Guarantor hereby waive any defense of payment
based upon any such tender or recovery which is not in the Required Currency,
or which, when exchanged for the Required Currency by the Trustee, is less than
the full amount of Required Currency then due and payable.

        Each Security shall be in a form approved from time to time by or

SECTION 2.05.   Securities Issuable in the Form
                of a Global Security.

        (a) If the Company shall establish pursuant to Section 3.01 that the
Securities of a particular series are to be issued in whole or in part in one
or more Global Securities as Registered Securities or Unregistered Securities,
then the Company shall execute and the Trustee shall, in accordance with
Section 3.03 and the Company Order delivered to the Trustee thereunder,
authenticate and deliver a Global Security or Securities which (i) shall
represent, and shall be denominated in an amount equal to the aggregate
principal amount of, the Outstanding Securities of such series to be
represented by such Global Security or Securities, (ii) shall be registered in
the name of the Depositary for such Global Security or Securities or its
nominee, (iii) shall be delivered by the Trustee to the Depositary or pursuant
to the Depositary's instruction, and (iv) shall bear a legend substantially to
the following effect: "Except as otherwise provided in Section 2.05 of the
Indenture, this Security may be transferred, in whole but not in part, only to
a nominee of the Depositary, or by a nominee of the Depositary to the
Depositary, or to a successor Depositary or to a nominee of such successor
Depositary."

        Each Depositary designated pursuant to Section 3.01 for a Global
Security that is a Registered Security must at the time of its designation and
at all times while it serves as Depositary, be a clearing agency registered
under the Securities and Exchange Act of 1934, as amended, and any other
applicable statute or regulation.

        (b) Notwithstanding any other provision of this Section 2.05 or of
Section 3.05, the Global Security of a series may be transferred, in whole but
not in part and in the manner provided in Section 3.05, only to a nominee of
the Depositary for such series or by a nominee of the Depositary to the
Depositary, or to a successor Depositary for such series selected or approved
by the Company or to a nominee of such successor Depositary.

        (c) If at any time the Depositary for a series of Securities notifies
the Company that it is unwilling or unable to continue as Depositary for such
series or if at any time the Depositary for such series shall no longer be
eligible under Section 2.05(a) and a successor Depositary for such series is
not appointed by the Company within 90 days after the Company receives such
notice or becomes aware of such condition, as the case may be, this Section
2.05 shall no longer be applicable to the


<PAGE>   33
                                     - 23 -


Securities of such series and the Company will execute, and the Trustee will,
in accordance with Section 3.03 and a Company Order delivered to the Trustee,
authenticate and deliver, Securities of such series, in like tenor and terms in
definitive form, in authorized denominations, and in an aggregate principal
amount equal to the principal amount of the Global Security of such series in
exchange for such Global Security. In addition, the Company may at any time
determine that the Securities of any series shall no longer be represented by a
Global Security and that the provisions of this Section 2.05 shall no longer
apply to the Securities of such series. In such event the Company will execute
and the Trustee, upon receipt of an Officers' Certificate evidencing such
determination by the Company, will authenticate and deliver Securities of such
series, in like tenor and terms in definitive form, in authorized
denominations, and in an aggregate principal amount equal to the principal
amount of the Global Security of such series in exchange for such Global
Security. If specified by the Company pursuant to Section 3.01 with respect to
a series of Securities, the Depositary for such series of Securities may
surrender a Global Security for such series of Securities in exchange in whole
or in part for Securities of such series of like tenor and terms and in
definitive form on such terms as are acceptable to the Company, the Trustee and
such Depositary. Thereupon, the Company shall execute, and the Trustee, upon
receipt of an Officer's Certificate evidencing such determination by the
Company, will authenticate and deliver definitive Securities of such series
without service charge:

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

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

        In any exchange provided for in this Section 2.05(c), the Company will
execute and the Trustee, pursuant to a Company Order, will authenticate and
deliver Securities

                (i) as Registered Securities in authorized denominations, if
        the Securities of such series are issuable as Registered Notes;


<PAGE>   34

                                     - 24 -


                (ii) as Unregistered Securities in authorized denominations,
        with Coupons, if the Securities of such series are issuable as
        Unregistered Securities; or

                (iii) as either Registered or Unregistered Securities, if the
        Securities of such series are issuable in either form.

        Upon the exchange of a Global Security for Securities in definitive
form, such Global Security shall be cancelled by the Trustee. Registered
Securities issued in exchange for a Global Security pursuant to this Section
shall be registered in such names and in such authorized denominations, and
delivered to such addresses, as the Depositary for such Global Security,
pursuant to instructions from its direct or indirect participants or otherwise,
shall instruct the Trustee in writing. The Trustee shall deliver such
Registered Securities to the persons in whose names such Securities are so
registered or to the Depositary in accordance with a Company Order. The Trustee
shall deliver Unregistered Securities issued in exchange for a Global Security
pursuant to this Section to the Depositary or to the Persons at such addresses,
and in such authorized denominations, as the Depositary for such global Note,
pursuant to instructions from its direct or indirect participants or otherwise
shall instruct the Trustee in writing.

        respectively, enforceable in accordance with their terms (subject, as
        to enforcement of remedies to applicable bankruptcy, reorganization,
        insolvency, moratorium or other laws affecting creditors' rights
        generally from time to time in effect) and entitled to the benefits of
        this Indenture, equally and ratably with all other Guarantees and all
        other Securities, if any, of such series Outstanding;

                (v) the amount of the Securities Outstanding, including such
        Securities, does not exceed the amount at the time permitted by law;


<PAGE>   39
                                     - 29 -


                (vi) this Indenture is qualified under the Trust Indenture Act;
        and

                (vii) the issuance of such Securities will not contravene the
        Articles of Incorporation or the By-Laws of the Company or the
        Guarantor or result in any violation of any of the terms or the
        provisions of any indenture, mortgage or other agreement known to such
        counsel by which the Company, the Guarantor or any of its subsidiaries
        is bound.

        In addition, the opinion and the Officers' Certificate will cover such
other matters as the Trustee may reasonably request.

SECTION 3.02.  Denominations.

        The Securities of each series shall be issuable in such denominations
as shall be specified in the form of Security for such series approved or
established pursuant to Section 2.03 or in the Officers' Certificate delivered
pursuant to Section 3.01. In the absence of any specification with respect to
the Securities of any series, the Securities of such series shall be issuable
as Fully Registered Securities in denominations of $1,000 or any integral
multiple thereof, and shall be payable in Dollars.

SECTION 3.03.  Execution, Authentication and Delivery.

        The Securities and Coupons, if any, appertaining thereto, shall be
executed on behalf of the Company and the Guarantees endorsed thereon shall be
executed on behalf of the Guarantor by, respectively, its Chairman, Vice
Chairman, President or one of its Executive Vice Presidents or Senior Vice
Presidents under its corporate seal, which may be in facsimile form and may be
imprinted or otherwise reproduced thereon and attested by its Secretary or one
of its Assistant Secretaries. The signature of any of these officers on the
Securities and Coupons, if any, appertaining thereto, or Guarantees may be
manual or facsimile. Typographical and other minor errors or defects in any
such reproduction of the seal or any such signature shall not affect the
validity or enforceability of any Security or Coupon that has been duly
authenticated and delivered by the Trustee.

        Securities and Coupons, if any, appertaining thereto, and Guarantees
bearing the manual or facsimile signatures of individuals who were at any time
the proper officers of the Company or the Guarantor, respectively, shall bind
the Company and the Guarantor, respectively, notwithstanding that such
individuals or any of them have ceased to hold such offices prior to the
authentication and delivery of such Securities, and Coupons, if


<PAGE>   40
                                     - 30 -


any, appertaining thereto, or did not hold such offices at the date of such
Securities and Guarantees.

        At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities, and Coupons, if any,
appertaining thereto, of any series executed by the Company with Guarantees
endorsed thereon executed by the Guarantor to the Trustee for authentication;
and the Trustee shall authenticate and deliver such Securities, and Coupons, if
any, appertaining thereto, to or upon a Company Order, an Officers' Certificate
and an Opinion of Counsel without any further action by the Company or the
Guarantor.

        The Trustee shall have the right to decline to authenticate and deliver
any Security under this Section if the Trustee, being advised by counsel,
determines that such action may not lawfully be taken or if the Trustee in good
faith by its board of directors or trustees, executive committee, or a trust
committee of directors or trustees and/or vice presidents shall determine that
such action would expose the Trustee to personal liability.

        All Registered Securities shall be dated the date of their
authentication, provided, however, that if provided for in the form of
Security, interest may accrue from a date other than the authentication date.

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

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


<PAGE>   41
                                     - 31 -


the Opinion of Counsel delivered at or prior to such time of authentication
shall relate to all subsequent issuances of Securities of such series that are
identical to the Securities issued in the first issuance of Securities of such
series.

SECTION 3.04.  Temporary Securities.

        Pending the preparation of definitive Securities for any series, the
Company may execute and upon Company Order the Trustee shall authenticate and
deliver temporary Securities (having duly executed Guarantees thereon) for such
series (printed, lithographed, typewritten or otherwise reproduced, in each
case in form satisfactory to the Trustee). Temporary Securities of any series
shall be issuable in any authorized denomination, and substantially in the form
of the definitive Securities of such series in lieu of which they are issued
but with such omissions, insertions and variations as may be appropriate for
temporary securities, all as may be determined by the Company with the
concurrence of the Trustee. Temporary Securities may contain such reference to
any provisions of this Indenture as may be appropriate. Every temporary
Security shall be executed by the Company and the Guarantee thereon shall be
executed by the Guarantor and be authenticated by the Trustee upon the same
conditions and in substantially the same manner, and with like effect, as the
definitive Securities. Temporary Securities may be issued as Registered
Securities, or Unregistered Securities, with or without one or more Coupons
attached. Without unreasonable delay the Company shall execute and shall
furnish definitive Securities of such series and the Guarantor shall execute
the Guarantee thereon and thereupon temporary Securities of such series may be
surrendered in exchange therefor without charge to a Holder at the Corporate
Trust Office of the Trustee, or, in the case of temporary Securities issued in
respect of Unregistered Securities of any series, at the Corporate Trust Office
of the Trustee located in a city specified elsewhere in this Indenture or
pursuant to Section 3.01, and the Trustee shall authenticate and deliver in
exchange for such temporary Securities an equal aggregate principal amount of
definitive Securities of the same series with appropriate Coupons, if any,
attached. Such exchange shall be made by the Company at its own expense and
without any charge therefor to a Holder except that in case of any such
exchange involving any registration of transfer the Company may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto. Until so exchanged, the temporary Securities of
any series and the Guarantees endorsed thereon shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series and the Guarantees endorsed thereon authenticated and delivered
hereunder.

SECTION 3.05.   Registration,  Registration of Transfer and Exchange.

        Subject to the conditions set forth below, Securities of any series may
be exchanged for a like aggregate principal amount of Securities of the same
series (having Guarantees endorsed thereon) of other authorized denominations.
Securities to be exchanged shall be surrendered together, in the case of Coupon
Securities, with all unmatured Coupons and matured Coupons in default
appertaining thereto, at the offices or agencies to be maintained by the
Company for such purposes as provided in Section 5.02, and the Company shall
execute and register, the Guarantor shall execute the Guarantees endorsed
thereon, and the Trustee shall authenticate and deliver in exchange therefor
the Security or Securities which the Holder making the exchange shall be
entitled to receive.

        The Company shall keep or cause to be kept, at one of its said offices
or agencies, a register for each series of Securities issued hereunder which
may include Registered Securities (hereinafter collectively referred to as the
"Securities Register") in which, subject to such reasonable regulations as it
may prescribe, and subject also to the provisions of Section 2.05, the Company
shall provide for the registration of Registered Securities of such series and
shall register the transfer of Registered Securities of such series as in this
Article Three provided. The Securities Register shall be in written form or in
any other form capable of being converted into written form within a reasonable
time. The Trustee is hereby appointed "Securities Registrar" for the purpose of
registering Registered Securities and registering transfers of Registered
Securities as herein provided. Subject to the provisions of Section 2.05, upon
due presentment for registration of transfer of any Security of any series at
any such office or agency, the Company shall execute and register, the
Guarantor shall execute the Guarantees endorsed thereon, and the Trustee shall
authenticate and deliver in the name of the transferee or transferees a new
Registered Security or Securities of the same series (having Guarantees
endorsed thereon) for an equal aggregate principal amount.

        Subject to the provisions of Section 2.05, at the option of the Holder
thereof, Securities of any series, whether Registered Securities or
Unregistered Securities, which by their terms are registrable as to principal
only or as to principal and interest, may, to the extent and under the
circumstances specified pursuant to Section 3.01, be exchanged for such
Registered Securities with Coupons or Fully Registered Securities of such
series, as may be issued by the terms thereof. Securities of any series,
whether Registered Securities or Unregistered Securities, which by their terms
provide for the issuance of Unregistered Securities, may not, except to the
extent and under the circumstances specified


<PAGE>   43
                                     - 33 -


pursuant to Section 3.01, be exchanged for Unregistered Securities of such
series. Unregistered Securities of any series issued in exchange for Registered
Securities of such series between the record date for such Registered
Securities and the next Interest Payment Date will be issued without the Coupon
relating to such Interest Payment Date, and Unregistered Securities surrendered
in exchange for Registered Securities between such dates shall be surrendered
without the Coupon relating to such Interest Payment Date and interest will not
be payable on such Interest Payment Date in respect of the Registered Security
issued in exchange for such Unregistered Security, but will be payable only to
the Holder of such Coupon when due in accordance with the provisions of this
Indenture.

        Upon presentation for registration of any Unregistered Security of any
series which by its terms is registrable as to principal, at the office or
agency of the Company and Guarantor to be maintained as provided in Section
5.02, such Security shall be registered as to principal in the name of the
Holder thereof, and such registration shall be noted on such Security. Any
Security so registered shall be transferable on the Securities Register of the
Company upon presentation of such Security at such office or agency for similar
notation thereon, but, to the extent permitted by law, such Security may be
discharged from registration by being in a like manner transferred to bearer,
whereupon transferability by delivery shall be restored. To the extent
permitted by law, Unregistered Securities shall continue to be subject to
successive registrations and discharges from registration at the option of the
Holders thereof.

        Unregistered Securities and Coupons shall be transferred by delivery.
All Securities presented for registration of transfer or for exchange,
redemption or payment shall (if so required by the Company or the Securities
Registrar) be duly endorsed by, or be accompanied by a written instrument or
instruments of transfer in form satisfactory to the Company and the Securities
Registrar duly executed by, the Holder thereof or his attorney duly authorized
in writing.

        Each Security and Guarantee endorsed thereon issued upon registration
of transfer or exchange of Securities pursuant to this Section 3.05 shall be
the valid obligation of the Company and Guarantor, evidencing the same
indebtedness and entitled to the same benefits under this Indenture as the
Security or Securities surrendered upon registration of such transfer or
exchange.

        No service charge shall be made to a Holder for any registration of
transfer or exchange of Securities, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any registration of transfer or exchange of
Securities, other


<PAGE>   44
                                     - 34 -


than exchanges pursuant to Section 3.04, 4.03 or 9.06 not involving
any transfer.

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

        None of the Company, the Trustee, any Paying Agent or Securities
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interest.

SECTION 3.06.   Mutilated, Defaced, Destroyed, Lost and Stolen
                Securities or Coupons.

        In case any temporary or definitive Security or Coupon shall become
mutilated or defaced or be destroyed, lost or stolen, and in the absence of
notice to the Company, the Guarantor, or the Trustee that such Security or
Coupon has been acquired by a bona fide purchaser, the Company in the case of a
mutilated Security or Coupon shall, and in the case of a lost, stolen or
destroyed Security or Coupon may in its discretion, execute, and upon a Company
Request, the Trustee shall authenticate and deliver, a new Security with like
Coupons, if any, as those attached to the mutilated, destroyed, lost or stolen
Security (so that neither gain nor loss in interest shall result), of the same
series, with a duly executed Guarantee thereon, of like tenor and principal
amount, and bearing a number, letter or other distinguishing symbol not
contemporaneously outstanding, or a new Coupon, as appropriate, in exchange and
substitution for the mutilated Security or Coupon, or in lieu of and in
substitution for the Security or Coupon so destroyed, lost or stolen, or if any
such Security or Coupon shall have matured or shall be about to mature, instead
of issuing a substituted Security or Coupon, the Company in its discretion may
pay or authorize the payment of the same without surrender thereof (except in
the case of a mutilated Security or Coupon) instead of issuing a new Security
or Coupon; provided, however, that interest 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, unless otherwise provided pursuant
to Section 3.01. In every case the applicant for a substituted Security or
Coupon shall furnish to


<PAGE>   45
                                     - 35 -


the Company, the Guarantor and the Trustee such security or indemnity as may be
required by them to save each of them harmless, and, in every case of
destruction, loss or theft, the applicant shall also furnish to the Company,
the Guarantor, and the Trustee evidence to their satisfaction of the
destruction, loss or theft of such Security or Coupon and of the ownership
thereof.

        Upon the issuance of any substitute Security or Coupon under this
Section 3.06, 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 substitute Security or Coupon of any series issued pursuant to
the provisions of this Section 3.06 by virtue of the fact that any such
Security is destroyed, lost or stolen shall constitute an additional
contractual obligation of the Company, guaranteed by the Guarantor, whether or
not the destroyed, lost or stolen Security or Coupon shall be at any time
enforceable by anyone and shall be entitled to all the benefits of (but shall
be subject to all the limitations of rights set forth in) this Indenture
equally and proportionately with any and all other Securities and Coupons of
such series duly authenticated and delivered hereunder. All Securities and
Coupons shall be held and owned upon the express condition that, to the extent
permitted by law, the foregoing provisions of this Section 3.06 are exclusive
with respect to the replacement or payment of mutilated, defaced or destroyed,
lost or stolen Securities and Coupons and shall, to the fullest extent
permitted under applicable law, preclude any and all other rights or remedies
notwithstanding any law or statute existing or hereafter enacted to the
contrary with respect to the replacement or payment of negotiable instruments
or other securities without their surrender.

SECTION 3.07.  Payment of Interest; Interest Rights Preserved.

        Unless otherwise specified as contemplated by Section 3.01, interest on
any Fully 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 at the
close of business on the Regular Record Date for such interest if provided for
in the Board Resolution pursuant to Section 3.01. In the case of a Security
issued between a record date and the initial Interest Payment Date relating to
such record date, interest for the period beginning on the date of issue and
ending on such initial Interest Payment Date shall be paid to the person to
whom such Security shall have been originally issued. In the case of


<PAGE>   46
                                     - 36 -


Coupon Securities, the Holder of any Coupon shall be entitled to receive the
interest, if any, payable on such Interest Payment Date, upon surrender on such
Interest Payment Date of the Coupon appertaining thereto in respect of such
interest.

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

                (1) The Company or the Guarantor may elect to make payment of
        any Defaulted Interest to the Persons in whose names such Fully
        Registered Securities (or their respective Predecessor Securities) are
        registered at the close of business on a Special Record Date for the
        payment of such Defaulted Interest, which shall be fixed in the
        following manner. The Company or the Guarantor shall notify the Trustee
        in writing of the amount of Defaulted Interest proposed to be paid on
        each Fully Registered Security and the date of the proposed payment,
        and at the same time the Company or the Guarantor, as the case may be,
        shall deposit with the Trustee an amount of money equal to the
        aggregate amount proposed to be paid in respect of such Defaulted
        Interest or shall make arrangements satisfactory to the Trustee for
        such deposit prior to the date of the proposed payment, such money when
        deposited to be held in trust for the benefit of the Persons entitled
        to such Defaulted Interest as in this Clause provided. Thereupon the
        Trustee shall fix a Special Record Date for the payment of such
        Defaulted Interest which shall be not more than 15 nor less than 10
        days prior to the date of the proposed payment and not less than 10
        days after the receipt by the Trustee of the notice of the proposed
        payment. The Trustee shall promptly notify the Company or the
        Guarantor, as the case may be, of such Special Record Date, and, in the
        name and at the expense of the Company or the Guarantor, as the case
        may be, 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 a Fully Registered Security
        at his address as it appears in the Security Register, not less than 10
        days prior to such Special Record Date. The Trustee may, in its
        discretion, in the name and at the expense of the Company or the
        Guarantor, as the case may be, cause a similar notice to be published
        at least once in an Authorized Newspaper in the Place of Payment, but
        such publication shall not be a condition precedent to the
        establishment of such Special


<PAGE>   47
                                     - 37 -


        Record Date. Notice of the proposed payment of such Defaulted Interest
        and the Special Record Date therefor having been given as aforesaid,
        such Defaulted Interest shall be paid to the Persons in whose names the
        Fully Registered Securities (or their respective Predecessor
        Securities) are registered on such Special Record Date and shall no
        longer be payable pursuant to the following Clause (2).

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

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

SECTION 3.08.  Persons Deemed Owners.

        The Company, the Guarantor, the Trustee and any agent of the Company,
the Guarantor, or the Trustee may deem and treat the Person in whose name any
Registered Security shall be registered upon the Security Register for such
series as the absolute owner of such Security (notwithstanding any notation of
ownership or other writing thereon) for the purpose of receiving payment of
principal of, premium, if any, and (subject to Section 3.07), if such
registered Security is a Fully Registered Security, interest, if any, on, such
Registered Security and for all other purposes whatsoever, whether or not such
Security be overdue, and neither the Company, the Guarantor, the Trustee nor
any agent of the Company, the Guarantor, or the Trustee shall be affected by
notice to the contrary. The Company, the Guarantor, the Trustee, and any agent
of the Company, the Guarantor, or the Trustee may treat the Holder of any
Unregistered Security and the Holder of any Coupon, whether or not the Security
to which such Coupon appertained be registered, as the absolute owner of such
Security or Coupon for the purposes of receiving payment thereof or on account
thereof and for all other purposes whatsoever whether or not such Security or
Coupon be overdue, and neither the Company, the Guarantor, the Trustee, any
Paying Agent nor any Security Registrar shall be


<PAGE>   48
                                     - 38 -


affected by notice to the contrary. All such payments so made to any Holder for
the time being, or upon his order shall be valid, and, to the extent of the sum
or sums so paid, effectual to satisfy and discharge the liability for moneys
payable upon such Security or Coupon.

SECTION 3.09.   Cancellation of Securities; Destruction Thereof.

        All Securities surrendered for payment, redemption, registration of
transfer or exchange, or for credit against any payment in respect of a sinking
or analogous fund, and all Coupons surrendered for payment or exchange, if
surrendered to the Company, the Guarantor, or any Paying Agent or any
Securities Registrar, shall be delivered to the Trustee for cancellation or, if
surrendered to the Trustee, shall be cancelled by it, and no Securities or
Coupons shall be authenticated and delivered in lieu thereof except as
expressly permitted by any of the provisions of this Indenture. The Trustee
shall destroy cancelled Securities and Coupons held by it and deliver a
certificate of destruction to the Company. If the Company or the Guarantor
shall acquire any of the Securities, such acquisition shall not operate as a
redemption or satisfaction of the indebtedness represented by such securities,
or the Guarantee endorsed thereon, unless and until the same are delivered to
the Trustee for cancellation.

SECTION 3.10.   Computation of Interest.

        Except as otherwise specified in the form of Security for any series
approved or established pursuant to Section 2.03 or in the Officers'
Certificate delivered pursuant to Section 3.01 with respect to Securities of
any series, interest on the Securities of each series shall be computed on the
basis of a year of twelve 30-day months.

SECTION 3.11.  Currency and Manner of Payments in Respect of Securities.

        (a) With respect to Registered Securities of any series denominated in
Dollars or in Foreign Currency or in any currency unit, which hereafter shall
include without limitation ECU, with respect to which the Holders of Securities
of such series have not made the election provided for in paragraph (b) below,
the following payment provisions shall apply:

                (1) Except as provided in subparagraph (a)(2) or in paragraph
        (e) below, payment of the principal of and premium, if any, on any
        Registered Security will be made at the Place of Payment by delivery of
        a check in the currency


<PAGE>   49
                                     - 39 -


        or currency unit in which the Security is payable on the payment date
        against surrender of such Registered Security, and any interest on any
        Fully Registered Security will be paid at the Place of Payment by
        mailing a check in the currency or currency unit in which such interest
        is payable to the Person entitled thereto at the address of such Person
        appearing on the Securities Register.

                (2) Payment of the principal of, premium, if any, and (with
        respect to Fully Registered Securities only) interest on such Security
        may also, subject to applicable laws and regulations, be made at such
        other place or places as may be designated by the Company or Guarantor
        by any appropriate method.

        (b) With respect to Registered Securities of any series denominated in
any Foreign Currency or currency unit the following payment provisions shall
apply, except as otherwise provided in paragraphs (e) and (f) below:

                (1) It may be provided pursuant to Section 3.01 with respect to
        the Securities of such series that Holders shall have the option to
        receive payments of principal of, premium, if any, and (with respect to
        Fully Registered Securities only) interest, if any, on such Securities
        in any of the currencies which may be designated for such election in
        such Securities by delivering to the Trustee a written election, to be
        in form and substance satisfactory to the Trustee, prior to the close
        of business on the record date immediately preceding the applicable
        payment date. Such election will remain in effect for such Holder until
        changed by the Holder by written notice to the Trustee (but any such
        change must be made prior to the close of business on the record date
        immediately preceding the next payment date to be effective for the
        payment to be made on such payment date and no such change may be made
        with respect to payments to be made on any Security of such series with
        respect to which notice of redemption has been given by the Company
        pursuant to Article Four). Any Holder of any such Security who shall
        not have delivered any such election to the Trustee prior to the close
        of business on the applicable record date will be paid the amount due
        on the applicable payment date in the relevant currency unit as
        provided in paragraph (a) of this Section 3.11. Payment of principal of
        and premium, if any, shall be made on the payment date against
        surrender of such Security. Payment of interest, if any, shall be made
        at the Place of Payment by mailing at such location a check, in the
        applicable currency or currency unit, to the Person entitled thereto at
        the address of such Person appearing on the Securities Register.

                (2) Payment of the principal of, premium, if any, and (with
        respect to Fully Registered Securities only) interest, if any, on such
        Security may also, subject to applicable laws and regulations, be made
        at such other place or places as may be designated by the Company or
        Guarantor by any appropriate method.

        (c) Payment of the principal of and premium, if any, on any
Unregistered Security and of interest on any Coupon Security will be made
unless otherwise specified pursuant to Section 3.01 or Section 9.01(6) by a
Paying Agent at such place or places outside the United States as may be
designated by the Company or Guarantor pursuant to any applicable laws or
regulations by any appropriate method in the currency or currency unit in which
the Security is payable (except as provided in paragraph (e) below) on the
payment date against surrender of the Unregistered Security, in the case of
payment of principal and premium, if any, or the relevant Coupon, in the case
of payment of interest, if any. Except as provided in paragraph (e) below,
payment with respect to Unregistered Securities and Coupons will be made by
check, subject to any limitations on the methods of effecting such payment as
shall be specified in the terms of the Security established as provided in
Section 3.01 and Section 9.01(6) and as shall be required under applicable laws
and regulations.

        (d) Not later than the fourth Business Day after the record date for
each payment date, the Trustee will deliver to the Company and the Guarantor a
written notice specifying, in the currency or currency unit in which each
series of the Securities is payable, the respective aggregate amounts of
principal of, premium, if any, and interest, if any, on the Securities to be
made on such payment date, specifying the amounts so payable in respect of
Fully Registered Securities, Registered Securities with Coupons and
Unregistered Securities and in respect of the Registered Securities as to which
the Holders of Securities denominated in any currency unit shall have elected
to be paid in another currency as provided in paragraph (b) above. If the
election referred to in paragraph (b) above has been provided for pursuant to
Section 3.01 and if at least one Holder has made such election, then, not later
than the second Business Day preceding each payment date the Company will
deliver to the Trustee and each Paying Agent an Exchange Rate Officer's
Certificate in respect of the Dollar or Foreign Currency payments to be made on
such payment date. The Dollar or Foreign Currency amount receivable by Holders
of Registered Securities denominated in a currency unit who have elected
payment in such currency as provided in paragraph (b) above shall be determined
by the Company on the basis of the applicable Official Currency Unit Exchange
Rate set forth in the applicable Exchange Rate Officer's Certificate.


<PAGE>   51
                                     - 41 -


        (e) If a Foreign Currency in which any of the Securities are
denominated or payable ceases to be used both by the government of the country
which issued such currency and for the settlement of transactions by public
institutions of or within the international banking community, or if the ECU
ceases to be used both within the European Monetary System and for the
settlement of transactions by public institutions of or within the European
Communities, or if any other currency unit in which a Security is denominated
or payable ceases to be used for the purposes for which it was established,
then with respect to each date for the payment of principal of, or premium, if
any, and interest, if any, on the applicable Securities denominated or payable
in such Foreign Currency, the ECU or such other currency unit occurring after
the last date on which such Foreign Currency, the ECU or such other currency
unit was so used (the "Conversion Date"), the Dollar shall be the currency of
payment for use on each such payment date. The Dollar amount to be paid by the
Company or the Guarantor to the Paying Agent and by the Paying Agent to the
Holders of such Securities with respect to such payment date shall be the
Dollar Equivalent of the Foreign Currency or, in the case of a currency unit,
the Dollar Equivalent of the Currency Unit as determined by the Dollar
Determination Agent as of the record date, if any, with respect to any Interest
Payment Date, or the fifteenth day before the Maturity of an installment of
principal (the "Valuation Date"), in the manner provided in paragraph (g) or
(h) below.

        (f) If the Holder of a Registered Security denominated in a currency
unit elects payment in a specified Foreign Currency as provided for by
paragraph (b) and such Foreign Currency ceases to be used both by the
government of the country which issued such currency and for the settlement of
transactions by public institutions of or within the international banking
community, such Holder shall receive payment in such currency unit, and if ECU
ceases to be used both within the European Monetary System and for the
settlement of transactions by public institutions of or within the European
Communities, or if any other such currency unit ceases to be used for the
purposes for which it was established, such Holder shall receive payment in
Dollars.

        (g) The "Dollar Equivalent of the Foreign Currency" shall be determined
by, and shall be set forth in a certificate delivered to the Company, the
Guarantor, the Trustee and each Paying Agent of, the Dollar Determination Agent
as of each Valuation Date and shall be obtained by converting the specified
Foreign Currency into Dollars at the Market Exchange Rate on the Valuation
Date.

        (h) The "Dollar Equivalent of the Currency Unit" shall be determined
by, and shall be set forth in a certificate delivered to the Company, the
Guarantor, the Trustee and each Paying Agent


<PAGE>   52
                                     - 42 -


of, the Dollar Determination Agent as of each Valuation Date and shall be the
sum obtained by adding together the results obtained by converting the
Specified Amount of each Component Currency into Dollars at the Market Exchange
Rate on the Valuation Date for such Component Currency.

        (i) For purposes of Section 3.11 the following terms shall have the
following meanings:

        A "Component Currency" shall mean any currency which, on the Conversion
Date, was a component currency of the relevant currency unit.

        A "Specified Amount" of a Component Currency shall mean the number of
units or fractions thereof which such Component Currency represented in the
relevant currency unit on the Conversion Date. If after the Conversion Date the
official unit of any Component Currency is altered by way of combination or
subdivision, the Specified Amount of such Component Currency shall be divided
or multiplied in the same proportion. If after the Conversion Date two or more
Component Currencies are consolidated into a single currency, the respective
Specified Amounts of such Component Currencies shall be replaced by an amount
in such single currency equal to the sum of the respective Specified Amounts of
such consolidated Component Currencies expressed in such single currency, and
such amount shall thereafter be a Specified Amount and such single currency
shall thereafter be a Component Currency. If after the Conversion Date any
Component Currency shall be divided into two or more currencies, the Specified
Amount of such Component Currency shall be replaced by specified amounts of
such two or more currencies, the sum of which, at the Market Exchange Rate of
such two or more currencies on the date of such replacement, shall be equal to
the Specified Amount of such former Component Currency divided by the number of
currencies into which such Component Currency was divided, and such amounts
shall thereafter be Specified Amounts and such currencies shall thereafter be
Component Currencies.

        "Market Exchange Rate" shall mean for any currency the noon Dollar
buying rate for that currency for cable transfers quoted in New York City on
the Valuation Date as certified for customs purposes by the Federal Reserve
Bank of New York. If such rates are not available for any reason with respect
to one or more currencies for which an Exchange Rate is required, the Dollar
Determination Agent shall use, in its sole discretion and without liability on
its part, such quotation of the Federal Reserve Bank of New York as of the most
recent available date, or quotations from one or more major banks in New York
City or in the country of issue of the currency in question, or such other
quotations as the Dollar Determination Agent shall deem appropriate. Unless
otherwise specified by the Dollar Determination Agent, if there is


<PAGE>   53
                                     - 43 -


more than one market for dealing in any currency by reason of foreign exchange
regulations or otherwise, the market to be used in respect of such currency
shall be that upon which a nonresident issuer of securities designated in such
currency would purchase such currency in order to make payments in respect of
such securities.

        All decisions and determinations of the Dollar Determination Agent
regarding the Dollar Equivalent of the Foreign Currency, the Dollar Equivalent
of the Currency Unit and the Market Exchange Rate shall be in its sole
discretion and shall, in the absence of manifest error, be conclusive for all
purposes and irrevocably binding upon the Company, the Guarantor, the Trustee,
any Paying Agent and all Holders of the Securities and Coupons denominated or
payable in the relevant currency or currency units. In the event that a Foreign
Currency ceases to be used both by the government of the country which issued
such currency and for the settlement of transactions by public institutions of
or within the international banking community, the Company, after learning
thereof, will immediately give notice thereof to the Trustee (and the Trustee
will promptly thereafter give notice in the manner provided in Section 1.06 to
the Holders) specifying the Conversion Date. In the event the ECU ceases to be
used both within the European Monetary System and for the settlement of
transactions by public institutions of or within the European Communities, or
any other currency unit in which Securities or Coupons are denominated or
payable, ceases to be used for the purposes for which it was established, the
Company, after learning thereof, will immediately give notice thereof to the
Trustee (and the Trustee will promptly thereafter give notice in the manner
provided in Section 1.06 to the Holders) specifying the Conversion Date and the
Specified Amount of each Component Currency on the Conversion Date. In the
event of any subsequent change in any Component Currency as set forth in the
definition of Specified Amount above, the Company, after learning thereof, will
similarly give notice to the Trustee. The Trustee shall be fully justified and
protected in relying conclusively and acting upon information received by it
from the Company and the Dollar Determination Agent, if any, and shall not have
any duty or obligation to determine such information independently.

SECTION 3.12.  Unconditional Guarantee.

        The Guarantor hereby unconditionally guarantees to each Holder of a
Security and Coupons, if any, appertaining thereto authenticated and delivered
by the Trustee and to the Trustee, the due and punctual payment of the
principal of, sinking fund payment, if any, premium, if any, and interest on
such Security and Coupons, if any, appertaining thereto, net of any taxes
required to be withheld, when and as the same shall become due and


<PAGE>   54
                                     - 44 -


payable, whether by declaration thereof or otherwise, in accordance with the
terms of such Security or Coupons, if any, appertaining thereto and of this
Indenture. In case of default by the Company in the payment of any such
principal, sinking fund payment, premium or interest, the Guarantor agrees duly
and punctually to pay the same. The Guarantor hereby agrees that its
obligations hereunder or under any Guarantee shall be absolute and
unconditional irrespective of any invalidity, irregularity or unenforceability
of any such Security, or Coupons, if any, appertaining thereto or this
Indenture, any failure to enforce the provisions of any such Security, or
Coupons, if any, appertaining thereto or this Indenture, any waiver,
modification or indulgence granted to the Company with respect thereto by the
holder of such Security, or Coupons, if any, appertaining thereto or the
Trustee, or any other circumstances which may otherwise constitute a legal or
equitable discharge of a surety or guarantor. The Guarantor hereby waives
diligence, presentment, demand of payment, filing of claims with a court in the
event of merger or bankruptcy of the Company, any right to require a proceeding
first against the Company, protest or notice with respect to any such Security,
or Coupons, if any, appertaining thereto or the indebtedness evidenced thereby
and all demands whatsoever, and covenants that its obligation hereunder or
under any Guarantee will not be discharged as to any such Security, or Coupons,
if any, appertaining thereto except by payment in full of the principal thereof
and premium, if any, and interest thereon.

        The Guarantor shall be subrogated to all rights of the holder of any
Security and Coupons, if any, appertaining thereto against the Company in
respect of any amounts paid by the Guarantor pursuant to the provisions of any
Guarantee; provided, however, that the Guarantor shall not be entitled to
enforce, or to receive any payments arising out of or based upon, such right of
subrogation until the principal of and premium, if any, and interest then due
on all Securities and Coupons, if any, appertaining thereto shall have been
paid in full.

        The Guarantee set forth in this Section shall not be valid or become
obligatory for any purpose with respect to a Security, or Coupons, if any,
appertaining thereto until the certificate of authentication on such Security,
or Coupons, if any, appertaining thereto shall have been signed by the Trustee.

        The rights and claims of the Trustee and the Holders of Securities and
Coupons, if any, appertaining thereto against the Guarantor under this Section
3.12 will be subordinated to the extent provided in Section 12.04.

SECTION 3.13.  Execution of Guarantees.

        To evidence its Guarantee to the Holders of Securities and Coupons, if
any, appertaining thereto, specified in Section 3.12, the Guarantor hereby
agrees to execute the Guarantees, in substantially the form above described, to
be endorsed on each security and endorsed or referenced on each Coupon, if
any, appertaining thereto authenticated and delivered by the Trustee. Each
such Guarantee shall be signed on behalf of the Guarantor as set forth in
Section 3.03, prior to the authentication of the Security on which it is
endorsed, and the delivery of such Security by the Trustee, after the
authentication thereof hereunder, shall constitute due delivery of such
Guarantee on behalf of the Guarantor.

                                  ARTICLE FOUR

                            REDEMPTION OF SECURITIES

SECTION 4.01.  Applicability of Article.

        The provisions of this Article shall be applicable to the Securities of
any series which are redeemable before their maturity or to any sinking fund
for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 3.01 for Securities of such series.

SECTION 4.02.  Notice of Redemption; Selection of Securities.

        In case the Company shall desire to exercise the right to redeem all,
or, as the case may be, any part of the Securities of any series (or all or
part of the Unregistered Securities of such series or all or any part of the
Registered Securities of such series, if the terms and conditions of redemption
shall differ with respect to Unregistered Securities and Registered Securities
of such series as specified in the terms of such Securities established
pursuant to Section 3.01) in accordance with their terms, it shall fix a
Redemption Date and shall provide notice of such redemption to the Trustee at
least 60 days prior to such Redemption Date, and at least 30 and not more than
60 days prior to such Redemption Date to the Holders of Securities of such
series so to be redeemed as a whole or in part in the manner provided in
Section 1.06.

        Each such notice of redemption shall specify the Redemption Date, the
Redemption Price, the Place or Places of Payment, that the Securities of such
series are being redeemed at the option of the Company pursuant to provisions
contained in the terms of the Securities of such series or in a supplemental
indenture


<PAGE>   56
                                     - 46 -


establishing such series, if such be the case, together with a brief statement
of the facts permitting such redemption, that payment will be made upon
presentation and surrender of the applicable Securities, that, unless otherwise
specified in such notice, Coupon Securities of any series, if any, surrendered
for payment must be accompanied by all Coupons, if any, maturing subsequent to
the date fixed for redemption, failing which the amount of any such missing
Coupon or Coupons will be deducted from the sum due for payment, that any
interest accrued to the Redemption Date will be paid as specified in said
notice, and that on and after said Redemption Date any interest thereon or on
the portions thereof to be redeemed will cease to accrue. If less than all the
Securities of any series are to be redeemed the notice of redemption shall
specify the numbers of the Securities of such series to be redeemed, and, if
only Unregistered Securities of any series are to be redeemed, and if such
Unregistered Securities may be exchanged for Registered Securities, the last
date on which exchanges of Unregistered Securities for Registered Securities
not subject to redemption may be made. In case any Security of any series is to
be redeemed in part only, the notice of redemption shall state the portion of
the principal amount thereof to be redeemed and shall state that on and after
the Redemption Date, upon surrender of such Security and any Coupons
appertaining thereto, a new Security or Securities of such series in principal
amount equal to the unredeemed portion thereof and with appropriate Coupons
will be issued, or, in the case of Securities providing appropriate space for
such notation, at the option of the Holders, the Trustee, in lieu of delivering
a new Security or Securities as aforesaid, may make a notation on such Security
of the payment of the redeemed portion thereof.

        On or before (but at least one Business Day before, in the case of
payments made in a currency or currency unit other than Dollars) the
Redemption Date with respect to the Securities of any series stated in the
notice of redemption given as provided in this Section 4.02, the Company will
deposit with the Trustee or with one or more Paying Agents an amount of money
in the currency or currency unit in which the Securities of such series and any
Coupons appertaining thereto are payable (except as otherwise specified as
contemplated by Section 3.01 for the Securities of such series and except as
provided in Sections 3.11(b), 3.11(e) and 3.11(f) of this Indenture) sufficient
to redeem on such Redemption Date all the Securities or portions thereof so
called for redemption at the applicable Redemption Price, together with accrued
interest to such Redemption Date.

        If fewer than all the Securities of a series are to be redeemed (except
in the case of a redemption in whole of the Unregistered Securities, the Coupon
Securities, the Registered Securities or the Fully Registered Securities of
such series), the Company will give the Trustee written notice not less than 60
days


<PAGE>   57
                                     - 47 -


prior to the Redemption Date as to the aggregate principal amount of Securities
to be redeemed and the Trustee shall select, not more than 60 days prior to the
Redemption Date and in such manner as in its sole discretion it shall deem
appropriate and fair, the Securities of such series or portions hereof (in
multiples of 1,000 in the currency or currency unit in which the Securities of
such series are denominated, except as otherwise set forth in the applicable
form of Security) to be redeemed.

SECTION 4.03.  Payment of Securities Called for Redemption.

        If notice of redemption has been given as above provided, the
Securities or portions of Securities of the series specified in such notice
shall become due and payable on the Redemption Date and at the place or places
stated in such notice at the applicable Redemption Price, together with any
interest accrued to such Redemption Date, and on and after said Redemption Date
(unless the Company shall default in the payment of such Securities at the
applicable Redemption Price, together with any interest accrued to said
Redemption Date) any interest on the Securities or portions of Securities of
any series so called for redemption shall cease to accrue. On presentation and
surrender of such Securities and all Coupons, if any, appertaining thereto at a
Place of Payment in such notice specified, such Securities and Coupons or the
specified portions thereof shall be paid and redeemed by the Company at the
applicable Redemption Price, together with any interest accrued thereon to the
applicable Redemption Date in the currency or currency unit in which the
Securities of such series and the Coupons, if any, appertaining thereto are
payable (except as otherwise specified as contemplated by Section 3.01 for the
Securities of such series and except as provided in Sections 3.11(b), 3.11(e)
and 3.11(f) of this Indenture).

        If any Coupon Security surrendered for redemption shall not be
accompanied by all appurtenant Coupons maturing on or 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, the Guarantor, and
the Trustee, if there be furnished to them such security or indemnity as they
may require to save each of them and any Paying Agent harmless. If thereafter
the Holder of such Security shall surrender to any Paying Agent any such
missing Coupon in respect of which a deduction shall have been made from the
Redemption Price, such Holder shall be entitled to receive the amount so
deducted; provided, however, that, unless otherwise provided pursuant to
Section 3.01 or Section 9.01(6), interest 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.


<PAGE>   58
                                     - 48 -


        Upon presentation of any Security redeemed in part only and the
Coupons, if any, appertaining thereto, the Company shall execute and the
Trustee shall authenticate and deliver to or on the order of the Holder
thereof, at the expense of the Company, a new Security or Securities of such
series and the Coupons, if any, appertaining thereto, of authorized
denominations, in principal amount equal to the unredeemed portion of the
Securities so presented.

SECTION 4.04.  Sinking Funds.

        (a) The provisions of this Section shall be applicable to any sinking
fund for the retirement of Securities of a series except as otherwise specified
as contemplated by Section 3.01 for Securities of such series.

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

        (b) In lieu of making all or any part of any mandatory sinking fund
payment with respect to any Securities of a series in cash, the Company may, at
its option, deliver to the Trustee Outstanding Securities of such series
(together with the unmatured Coupons, if any, appertaining thereto) theretofore
purchased or otherwise acquired by the Company, except Securities of such
series which have been redeemed or previously called for redemption through the
application of mandatory or optional sinking fund payments pursuant to the
terms of the Securities of such series, accompanied by a Company Order
instructing the Trustee to credit such obligations and stating that the
Securities of such series were originally issued by the Company by way of bona
fide sale or other negotiation for value; provided that such Securities have
not been previously so credited. Such Securities shall be received and credited
for such purpose by the Trustee at the Redemption Price specified in such
Securities for redemption through operation of the sinking fund and the amount
of such mandatory sinking fund payment shall be reduced accordingly.

        (c) Not less than 60 days prior to each sinking fund payment date for
any series of Securities, the Company will deliver to the Trustee a certificate
signed by the Treasurer or any Assistant Treasurer of the Company specifying
the amount of the next ensuing sinking fund payment for such series pursuant to
the terms of such series, the portion thereof, if any, which is to be satisfied
by payment of cash in the currency or currency unit in which the Securities of
such series and the Coupons, if any,


<PAGE>   59
                                     - 49 -


appertaining thereto are payable (except as otherwise specified as contemplated
by Section 3.01 for the Securities of such series and except as provided in
Sections 3.11(b), 3.11(e) and 3.11(f) of this Indenture) and the portion
thereof, if any, which is to be satisfied by delivering and crediting
Securities of such series pursuant to subsection (b) of this Section and which
Securities are to be delivered and whether the Company intends to exercise its
right to make a permitted optional sinking fund payment with respect to such
series. Such certificate shall be irrevocable and upon its delivery the Company
shall be obligated to make the cash payment or payments (in the currency or
currency unit described above) therein referred to, if any, on or before the
next succeeding sinking fund payment date. In the case of the failure of the
Company to deliver such certificate (or to deliver the Securities and Coupons,
if any, specified in such certificate within the time period specified in
subsection (b) of this Section), the sinking fund payment due on the next
succeeding sinking fund payment date for such series shall be paid entirely in
cash (in the currency or currency unit described above) and shall be sufficient
to redeem the principal amount of the Securities of such series subject to a
mandatory sinking fund payment without the right to deliver or credit
Securities as provided in subsection (b) of this Section and without the right
to make any optional sinking fund payment, if any, with respect to such series.

        Any sinking fund payment or payments (mandatory or optional) made in
cash (in the currency or currency unit described above) plus any unused balance
of any preceding sinking fund payments made with respect to the Securities of
any particular series shall be applied by the Trustee on the sinking fund
payment date on which such payment is made (or, if such payment is made before
a sinking fund payment date, on the sinking fund payment date following the
date of such payment) to the redemption of Securities of such series at the
Redemption Price specified in such Securities with respect to the sinking fund
together with accrued interest, if any, to the applicable Redemption Date. Any
excess sinking fund moneys not so applied or allocated by the Trustee to the
redemption of Securities shall be added to the next sinking fund payment
received by the Trustee for such series and, together with such payment (or
such amount so segregated) shall be applied in accordance with the provisions
of this subsection (c) of this Section 4.04. Any and all sinking fund moneys
with respect to the Securities of any particular series held by The Trustee on
the last sinking fund payment date with respect to Securities of such series
and not held for the payment or redemption of particular Securities of such
series shall be applied by the Trustee together with other moneys, if
necessary, to be deposited (or segregated) sufficient for the purpose, to the
payment of the principal of the Securities of such series at Maturity. The
Trustee shall not convert any currency or currency


<PAGE>   60
                                     - 50 -


unit in which the Securities of such series are payable for the purposes of
such sinking fund application unless specifically requested to do so by the
Company, and any such conversion agreed to by the Trustee in response to such
request shall be for the account and at the expense of the Company and shall
not affect the Company's obligation to pay the Holders in the currency or
currency unit to which such Holders may be entitled.

        The Trustee shall select or cause to be selected the Securities to be
redeemed upon such sinking fund payment date in the manner specified in the
last paragraph of Section 4.02 and the Company shall cause notice of the
redemption thereof to be given in the manner provided in Section 4.02 except
that the notice of redemption shall also state that the Securities are being
redeemed by operation of the sinking fund and whether the sinking fund payment
is mandatory or optional, or both, as the case may be. Such notice having been
duly given, the redemption of such Securities shall be made upon the terms and
in the manner stated in Section 4.03.

        On or before the opening of business on (but at least one Business Day
before, in the case of payments made in a currency or currency unit other than
Dollars) each sinking payment date, the Company shall pay to the Trustee in
cash (in the currency or currency unit described in the first paragraph of this
subsection 4.04(c)) a sum equal to the principal and any interest accrued to
the Redemption Date for Securities or portions thereof to be redeemed on such
sinking fund payment date pursuant to this Section.

SECTION 5.01.   Payment of Principal, Premium and Interest;
                Compliance with Terms.

        With respect to each series of Securities, the Company will duly and
punctually pay the principal of, premium, if any, and interest on the
Securities of such series in accordance with the terms of the Securities of
such series of Securities, any Coupons appertaining thereto and this Indenture,
net of any taxes required to be withheld, and will duly comply with all the
other terms, agreements and conditions contained in, or made in this Indenture
for the benefit of, the Securities of such series. Each installment of interest
on the Registered Securities of any series may be paid by mailing checks for
such interest payable to or upon the written order of the Holders of Registered
Securities entitled thereto as they shall appear on the registry books of the
Company.


<PAGE>   61
                                     - 51 -


        The interest on Coupon Securities shall be payable only upon
presentation and surrender of the several Coupons for such interest
installments as are evidenced thereby as they severally mature. The interest,
if any, on any temporary Unregistered Security shall be paid, as to any
installment of interest evidenced by a Coupon attached thereto, if any, only
upon presentation and surrender of such Coupon, and, as to other installments
of interest, if any, only upon presentation of such Security for notation
thereon of the payment of such interest.

SECTION 5.02.  Maintenance of Agency.

        The Company and the Guarantor will maintain an office or agency in the

        The Company and the Guarantor, by written notice to the Trustee, may
also from time to time designate one or more other offices or agencies where
Securities may be presented for any or all such purposes, and, by like notice,
may from time to time rescind such designations.

SECTION 5.03.  Money for Security Payments To Be Held in Trust.

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

        Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, prior to each due date of the principal of,
premium, if any, or interest on any Securities of such series, and Coupons, if
any, appertaining thereto, deposit, subject to Section 4.04(c), with a Paying
Agent a sum sufficient to pay the principal, premium or interest so becoming
due, such sum to be held in trust for the benefit of the Persons entitled to
such principal, premium or interest, and (unless such Paying Agent is the
Trustee) the Company will promptly notify the Trustee of its action or failure
so to act.

        The Company will cause each Paying Agent 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 and the Company, subject
to the provisions of this Section, that such Paying Agent will:

                (1) hold all sums held by it for the payment of principal of or
        premium, if any, or any interest on Securities of such series or any
        Coupon appertaining thereto in trust for the benefit of the Persons
        entitled thereto until such sums shall be paid to said Persons or
        otherwise disposed of as herein provided;

                (2) give the Trustee notice of any default by the Company or
        the Guarantor (or any other obligor upon the Securities of such series)
        in the making of any payment of principal of, premium or interest on
        the Securities of such series or Coupon, if any, appertaining thereto;
        and


<PAGE>   63
                                     - 53 -


                (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 trusts as those upon which such sums were held by the
Company or such Paying Agent; and, upon such payment by any Paying Agent to the
Trustee, such Paying Agent shall be released from all further liability with
respect to such sums.

        Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of or premium, if
any, or interest on any Security of any series or any Coupon appertaining
thereto and remaining unclaimed for 2 years after such principal 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 Coupon, if any, appertaining thereto shall
thereafter, as an unsecured general creditor, look only to the Company and the
Guarantor 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 the Place of Payment, notice that such money remains unclaimed and that,
after a date specified therein, which shall not be less than 30 days from the
date of such publication, any unclaimed balance of such money then remaining
will be repaid to the Company. The Trustee may also adopt and employ, at the
expense of the Company, any other reasonable means of notification of such
proposed repayment (including, but not limited to, mailing notice of such
proposed repayment to Registered Holders whose names appear on the Security
Register and whose holdings of Registered Securities have not yet been
surrendered for redemption or whose right to interest moneys due and payable
but not claimed is determinable from the records of any Paying Agent or the
Trustee, at the last address of record for each such Holder).

SECTION 5.04.   Certification of Compliance of the Company
                and the Guarantor.

        Each of the Company and the Guarantor will promptly (and in any event
within 3 Business Days) notify the Trustee, upon


<PAGE>   64
                                     - 54 -


obtaining knowledge of any default under this Indenture and shall comply with
the provisions of Section 314(a)(4) of the Trust Indenture Act.

SECTION 5.05.   Corporate Existence.

        Subject to Article Ten, the Company and the Guarantor will do or cause
to be done all things necessary to preserve and keep in full force and effect
their respective corporate existence, rights (charter and statutory) and
franchises and the corporate existence, rights (charter and statutory) and
franchises of all Subsidiaries other than the Company; provided, however, that
the Company and the Guarantor shall not be required to, or to cause any such
Subsidiary to, preserve any right or franchise or to keep in full force and
effect the corporate existence of any such Subsidiary if the Company (in the
case of the Company) or the Guarantor (in all other cases) shall determine that
the keeping in existence or preservation thereof is no longer desirable in the
conduct of the business of the Company or the Guarantor, as the case may be,
and that the loss thereof is not disadvantageous in any material respect to the
Holders of Securities or Coupons, if any, appertaining thereto.

SECTION 5.06.   Limitation on Sale or Issuance of Voting
                Shares of Principal Subsidiary Banks.

        The Guarantor will not (a) permit the issue, sale or other disposition
of any Voting Shares, or securities convertible into, or options, warrants or
rights to subscribe for or purchase Voting Shares, of any Principal Subsidiary
Bank, (b) permit the merger of consolidation of any Principal Subsidiary Bank
with or into any other corporation, or (c) permit the sale or other disposition
of all or substantially all of the assets of any Principal Subsidiary Bank, if,
after giving effect to any such transaction (specified in clauses (a), (b) or
(c) above) and the issuance of the maximum number of Voting Shares issuable
upon the conversion or exercise of all such convertible securities, options,
warrants or rights, the Guarantor would own, directly or indirectly, less than
80% of the Voting Shares of such Principal Subsidiary Bank (and of any other
Principal Subsidiary Bank any Voting Shares of which are owned, directly or
indirectly, by such Principal Subsidiary Bank); provided, however, that the
foregoing shall not prohibit any such issuance, sale or disposition of shares
or securities, any such merger or consolidation or any such sale or disposition
of assets if:

                (i) required by any law or any regulation or order of any
        governmental authority;


<PAGE>   65
                                     - 55 -


                (ii) required as a condition imposed by any law or any
        regulation or order of any governmental authority to the acquisition by
        the Guarantor, directly or indirectly, of any other corporation or
        entity, if thereafter, (x) the Guarantor would own, directly or
        indirectly, at least 80% of the Voting Shares of such other corporation
        or entity, and (y) the Consolidated Banking Assets of the Guarantor
        would be at least equal to the Consolidated Banking Assets of the
        Guarantor prior thereto, and (z) by a Board Resolution, such other
        corporation or entity shall have been designated a Principal Subsidiary
        Bank for all purposes or this Indenture;

                (iii) upon consummation of such transaction, the Guarantor
        owns, directly or indirectly, not less than the percentage of Voting
        Shares of such Principal Subsidiary Bank (and of any other Principal
        Subsidiary Bank any Voting Shares of which are owned, directly or
        indirectly, by such Principal Subsidiary Bank) it owned prior to such
        transaction; or

                (iv) the proceeds of any such issuance, sale or other
        disposition are invested within 180 days after such issuance, sale or
        other disposition in any one or more Subsidiary Banks (including any
        previously existing Subsidiary Bank or any other corporation which upon
        such investment becomes a Subsidiary Bank), or if within 180 days after
        such issuance, sale or other disposition the Guarantor has entered into
        an agreement to invest such proceeds in any one or more Subsidiary
        Banks (including any previously existing Subsidiary Bank or any other
        corporation which upon such investment would become a Subsidiary Bank),
        but such investment has not been made because all regulatory or other
        approvals have not been obtained but are in the process of being
        obtained, and if, in each case, the consolidated assets of the
        Subsidiary Bank(s) acquired or to be acquired or invested in (including
        any one or more corporations which upon such investment would become
        Subsidiary Banks) would be at least equal to 80% of the consolidated
        assets of the Principal Subsidiary Bank being disposed of; provided,
        however, that if the Guarantor makes a subsequent acquisition as
        described in this paragraph using its common stock and preferred stock,
        with a fair market value at least equal to the proceeds of any sale,
        assignment, transfer or disposition of a Principal Subsidiary Bank, it
        will not also be required to invest the proceeds of any sale
        assignment, transfer or disposition as otherwise required by this
        paragraph; provided, further, that the Guarantor will, for the purpose
        of satisfying this covenant, only issue preferred shares in a
        subsequent acquisition in an amount needed to replace any preferred
        stock of the acquired company;


<PAGE>   66
                                     - 56 -


        provided, however, that nothing herein shall be deemed to restrict or
        prohibit the merger of a Principal Subsidiary Bank with and into a
        Principal Subsidiary Bank or the Guarantor, the consolidation of
        Principal Subsidiary Banks into a Principal Subsidiary Bank or the
        Guarantor, or the sale or other disposition or all or substantially all
        of the assets of any Principal Subsidiary Bank to another Principal
        Subsidiary Bank or the Guarantor, if, in any such case in which the
        surviving, resulting or acquiring entity is not the Guarantor, the
        Guarantor would own, directly or indirectly, at least 80% of the Voting
        Shares of the Principal Subsidiary Bank (and of any other Principal
        Subsidiary Bank any Voting Shares of which are owned, directly or
        indirectly, by such Principal Subsidiary Bank) surviving such merger,
        resulting from such consolidation or acquiring such assets.

SECTION 5.07.  Ownership of the Company.

        Subject to Article Ten, the Guarantor will at all times continue to
own, directly or indirectly, all of the issued and outstanding Voting Shares of
the Company.

SECTION 5.08.  Liens.

        The Guarantor will not, and it will not permit any Subsidiary to,
pledge, mortgage or hypothecate or permit to exist any pledge, mortgage or
hypothecation or other lien upon Voting Shares of any Principal Subsidiary Bank
owned by the Guarantor or any Subsidiary to secure any indebtedness for
borrowed money without making effective provisions whereby any Senior Debt
Securities shall be equally and ratably secured with any and all such
indebtedness; provided, however, that this restriction shall not apply to or
prevent:

                (a) the mortgage, pledge, or hypothecation of, or the
        establishment of a lien on, any such Voting Shares to secure
        indebtedness of the Guarantor or a Subsidiary as part of the purchase
        price of such Voting Shares, or incurred prior to, at the time of or
        within 120 days after acquisition thereof for the purpose of financing
        all or any part of the purchase price thereof;

                (b) the acquisition by the Guarantor or any Subsidiary of any
        Voting Shares subject to mortgages, pledges, hypothecations or other
        liens existing thereon at the time of acquisition (whether or not the
        obligations secured thereby are assumed by the Guarantor or such
        Subsidiary);

                (c) the assumption by the Guarantor or a Subsidiary of
        obligations secured by mortgages on, pledge or hypothecations of, or
        other liens on, any such Voting Shares, existing at the time of the
        acquisition by the Guarantor or such Subsidiary of such Voting Shares;


<PAGE>   67
                                     - 57 -


                (d) the extension, renewal or refunding (or successive
        extensions, renewals or refundings), in whole or in part, of any
        mortgage, pledge, hypothecation or other lien referred to in the
        foregoing clauses (a), (b) and (c); provided, however, that the
        principal amount of any and all other obligations and indebtedness
        secured thereby shall not exceed the principal amount so secured at the
        time of such extension, renewal or refunding, and that such extension,
        renewal or refunding shall be limited to all or a part of the Voting
        Shares that were subject to the mortgage, pledge, hypothecation or
        other lien so extended, renewed or refunded; or

                (e) liens to secure loans or other extensions of credit by a
        Subsidiary Bank subject to Section 23A of the Federal Reserve Act or
        any successor or similar federal law or regulations promulgated
        thereunder;

and provided, further, that, notwithstanding the foregoing, the Guarantor may
incur or permit to be incurred or to exist upon such Voting Shares (a) liens
for taxes, assessments or other governmental charges or levies which are not
yet due or are payable without penalty or of which the amount, applicability or
validity is being contested by the Guarantor or a Subsidiary in good faith by
appropriate proceedings and the Guarantor or such Subsidiary shall have set
aside on its books adequate reserves with respect thereto (segregated to the
extent required by generally accepted accounting principles), or (b) the lien
of any judgment, if such judgment shall not have remained undischarged, or
unstayed on appeal or otherwise, for more than 60 days.

        In case the Guarantor or any Subsidiary shall propose to pledge,
mortgage or hypothecate any voting Shares at any time owned by it to secure any
indebtedness, other than as permitted by subdivisions (a) to (e), inclusive, of
this Section, the Guarantor will prior thereto give written notice thereof to
the Trustee, and will prior to or simultaneously with such pledge, mortgage or
hypothecation, by supplemental indenture delivered to the Trustee, in form
satisfactory to it, effectively secure all the Senior Debt Securities equally
and ratably with such indebtedness, by pledge, mortgage or hypothecation of
such Voting Shares. Such supplemental indenture shall contain the provisions
concerning the possession, control, release and substitution of mortgaged and
pledged property and securities and other appropriate matters which are
required or are permitted by the Trust Indenture Act (as in effect at the date
of execution of such supplemental indenture) to be included in a secured
indenture qualified under said Act, and may also contain such additional and
amendatory provisions permitted by said Act as the Guarantor and the Trustee
shall deem advisable or appropriate or as the Trustee shall deem necessary in
connection with such pledge, mortgage or hypothecation.

SECTION 5.09.   Waiver of Covenants.

        The Company or the Guarantor, as the case may be, may omit in respect
of any series of Securities in any particular instance to comply with any
covenant or condition set forth in Section 5.05 through 5.08 hereof, if before
or after the time for such compliance the Holders of a majority in principal
amount of the Securities of such series at the time Outstanding shall, by Act
of such Holders of Securities, either waive such compliance in such instance or
generally waive compliance with such covenant or condition, but no such waiver
shall extend to or affect such covenant or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the Guarantor and the duties of the Trustee in
respect of any such covenant or condition shall remain in full force and
effect.

        Guarantor or any Principal Subsidiary Bank or of any substantial part
        of its property, or the Company, the Guarantor or any Principal

        become due or shall take any corporate action in furtherance of any
        such action; or

                                     - 62 -


Board Resolution or in the supplemental indenture under which such series of
Securities is issued, as the case may be, as contemplated by Section 3.01:

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

                (2) default in the payment of the principal of (including any
        sinking fund payment or analogous obligation) or premium, if any, on
        any Security of such series as and when the same shall become due and
        payable either at Maturity, upon redemption, by declaration or
        otherwise;

                (3) default in the performance, or breach, of any covenant or
        warranty of the Company or the Guarantor in respect of the Securities
        of such series (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), and continuance of such default or
        breach for a period of 90 days after there has been given to the
        Company and the Guarantor by the Trustee, by registered or certified
        mail, or to the Company, the Guarantor and the Trustee by the Holders
        of at least 25% in principal amount of the Outstanding Securities of
        such series, a written notice specifying such default or breach and
        requiring it to be remedied; or

                (4) any other Default provided in the supplemental indenture
        under which such series of Securities is issued or in the form of
        Security for such series.

SECTION 7.02.  Acceleration of Maturity; Rescission and Annulment.

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


<PAGE>   73
                                     - 63 -


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

                (1) the Company or the Guarantor has paid or deposited with the
        Trustee a sum sufficient to pay in the currency or currency unit in
        which the Securities of such series are payable (except as otherwise
        specifically contemplated by Section 3.01 for the Securities of such
        series and except as provided in Sections 3.11(b), 3.11(e) and 3.11(f)
        of this Indenture)

                (A) all overdue installments of interest on all Securities of
        such series,

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

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

                (D) in Dollars all sums paid or advanced by the Trustee
        hereunder and the reasonable compensation, expenses, disbursements and
        advances of the Trustee, its agents and counsel, except as a result of
        negligence or bad faith; and

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

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

        In case the Trustee shall have proceeded to enforce any right under
this Indenture and such proceedings shall have been discontinued or abandoned
because of such rescission or annulment or for any other reason or shall have
been determined adversely to the Trustee, then and in every such case the
Company, the


<PAGE>   74
                                     - 64 -


Guarantor and the Trustee shall be restored respectively to their several
positions and rights hereunder, and all rights, remedies and powers of the
Company and the Trustee shall continue as though no such proceedings had been
taken.

        For all purposes under this Indenture, if a portion of the principal of
any Original Issue Discount Securities shall have been accelerated and declared
due and payable pursuant to the provisions hereof, then, from and after such
declaration, unless such declaration has been rescinded and annulled, the
principal amount of such Original Issue Discount Securities shall be deemed,
for all purposes hereunder, to be such portion of the principal thereof as
shall be due and payable as a result of such acceleration, and payment of such
portion of the principal thereof as shall be due and payable as a result of
such acceleration, together with interest, if any, thereon and all other
amounts owing thereunder, shall constitute payment in full of such Original
Issue Discount Securities.

SECTION 7.03.   Collection of Indebtedness and Suits for
                Enforcement by Trustee.

        The Company covenants that if:

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

                (2) default is made in the payment of the principal of
        (including any sinking fund payment or analogous obligation) or
        premium, if any, on any Security of any series, whether upon Maturity
        or upon any redemption or by declaration or otherwise,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of Securities of such series, and Coupons, if any, appertaining
thereto, the whole amount then due and payable on Securities of such series and
matured Coupons, if any, appertaining thereto for principal, premium, if any,
and interest, with interest upon the overdue principal and premium, if any, and
to the extent that payment of such interest is lawful, upon overdue
installments of interest, at the rate or rates prescribed therefor by the terms
of the Securities of such series; 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.


<PAGE>   75
                                     - 65 -


        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, the Guarantor or any other obligor upon such Securities
and Coupons and collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Company, the Guarantor or any
other obligor upon such Securities and Coupons, wherever situated.

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

SECTION 7.04.  Trustee May File Proofs of Claim.

        In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company, the Guarantor or any other obligor
upon the Securities and Coupons, if any, appertaining thereto or the property
of the Company, the Guarantor or of such other obligor or their creditors, the
Trustee (irrespective of whether the principal of any Securities and any
amounts owed pursuant to Coupons, if any, appertaining thereto 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
or the Guarantor for payment of overdue principal, premium or interest) shall
be entitled and empowered, by intervention in such proceeding or otherwise,

                (i) to file and prove a claim for the whole amount of
        principal, premium, if any, and interest owing and unpaid in respect of
        any Securities and Coupons, if any, appertaining thereto and to file
        such other papers or documents as may be necessary or advisable in
        order to have the claim of the Trustee (including any claim for the
        reasonable compensation, expenses, disbursements and advances of the
        Trustee, its agents and counsel) and of the Holders of Securities of
        any series and Coupons, if any, appertaining thereto allowed in such
        judicial proceeding, and


<PAGE>   76
                                     - 66 -


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

and any receiver, assignee, trustee, liquidator, sequestrator (or other similar
official) in any such judicial proceeding is hereby authorized by each Holder
of Securities or Coupons, if any, appertaining thereto to make such payments to
the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Security Holders, to pay to the Trustee any
amount due to it for the reasonable compensation expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 8.07. To the extent that such payment of reasonable
compensation, expenses, disbursements, advances and other amounts out of the
estate in any such proceedings shall be denied for any reason, payment of the
same shall be secured by a lien on, and shall be paid out of, any and all
distributions, dividends, moneys, securities and other property which the
Holders of the Securities or Coupons may be entitled to receive in such
proceedings, whether in liquidation or under any plan of reorganization or
arrangement or otherwise.

        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
Securities or Coupons, if any, appertaining thereto any plan of reorganization,
arrangement, adjustment or composition affecting the Securities and Coupons, if
any, appertaining thereto or the rights of any Holder thereof, or to authorize
the Trustee to vote in respect of the claim of any Holder of Securities or
Coupons, if any, appertaining thereto in any such proceeding.

SECTION 7.05.   Trustee May Enforce Claims Without Possession
                of Securities.

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

        In any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this


<PAGE>   77
                                     - 67 -


Indenture to which the Trustee shall be a party) the Trustee shall be held to
represent all the Holders of the Securities and Coupons in respect of which
such action was taken, and it shall not be necessary to make any Holders of
such Securities or Coupons parties to any such proceedings.

SECTION 7.06.  Application of Money Collected.

        Any money collected by the Trustee pursuant to this Article with
respect to a series of Securities or Coupons, if any, appertaining thereto
(other than sums held in trust for the benefit of the Holders of particular
Securities or Coupons) shall be applied in the following order, at the date or
dates fixed by the Trustee and in the case of the distribution of such money on
account of principal, premium, if any, or interest, upon presentation (except
in respect of Subdivision FIRST below) of the Securities of such series and
Coupons, if any, appertaining thereto, and the notation thereon of the payment
if only partially paid and upon surrender thereof if fully paid:

                FIRST: To the payment of all amounts due the Trustee under
        Section 8.07.

                SECOND: To the payment of the amounts then due and unpaid upon
        the Securities of such series and Coupons, if any, appertaining thereto
        for principal, premium, if any, and interest, in respect of which or
        for the benefit of which such money has been collected, ratably,
        without preference or priority of any kind, according to the amounts
        due and payable on such Securities of such series and Coupons, if any,
        appertaining thereto, for principal, premium, if any, and interest,
        respectively.

                THIRD: The balance, to the Person or Persons lawfully entitled
        thereto, or as a court of competent jurisdiction may direct.

SECTION 7.07.  Limitation on Suits.

        No Holder of any security of any series or Coupon, if any, appertaining
thereto 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 continued Event of Default or a Default with respect to
        Securities of such series;


<PAGE>   78
                                     - 68 -


                (2) the Holders of not less than 25% in principal amount of the
        Outstanding Securities of such series shall have made written request
        to the Trustee to institute proceedings in respect of such Event of
        Default or 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
        proceedings; 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 Holders of Securities of
such series or Coupons, if any, appertaining thereto shall have any right in
any manner whatever by virtue of, or by availing of, any provision of this
Indenture to affect, disturb, or prejudice the rights of any other Holders of
Securities of such series or Coupons, if any, appertaining thereto or to obtain
or to seek to obtain priority or preference over any other such Holders or to
enforce any right under this Indenture, except in the manner herein provided
and for the equal and ratable benefit of all the Holders of Securities of such
series and Coupons, if any, appertaining thereto.

SECTION 7.08.   Unconditional Right of Security Holders To
                Receive Principal, Premium and Interest.

any Security or Coupon, if any, appertaining thereto shall have the right which
is absolute and unconditional to receive payment of the principal of and
premium, if any, and (subject to Section 3.07) interest on such Security or a
Coupon on the respective Stated Maturities expressed in such Security or Coupon
(or, in the case of redemption or repayment, on the Redemption Date or
Repayment Date, as the case may be) at the respective places, at the respective
times, at the respective rates, in the respective amounts and in the coin,
currency, or currency unit therein and herein prescribed, and to institute suit
for the enforcement of any such payment, and such right shall not be impaired
without the consent of such Holder.


<PAGE>   79
                                     - 69 -


SECTION 7.09.  Restoration of Rights and Remedies.

        If the Trustee or any Holder of any Security or Coupon, if any,
appertaining thereto 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 of any Security or Coupon, if any, appertaining thereto, then and
in every such case the Company, the Guarantor, the Trustee and the Holders of
any Security or Coupons, if any, appertaining thereto 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 such Holders shall continue as though no such proceeding had been
instituted.

SECTION 7.10.  Rights and Remedies Cumulative.

        No right or remedy herein conferred upon or reserved to the Trustee or
to the Holders of any Securities or Coupons, if any, appertaining thereto is
intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at
law or in equity or otherwise. The assertion or employment of any right or
remedy hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

SECTION 7.11.  Delay or Omission Not Waiver.

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

SECTION 7.12.  Control by Security 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


<PAGE>   80
                                     - 70 -


power conferred on the Trustee under this Indenture with respect
to Securities of such series, provided that

                (1) such direction shall not be in conflict with any statute or
        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) the Trustee need not take any action which it determines
        might involve it in personal liability or would be unduly prejudicial
        to the Holders of Securities of such series not joining in such
        direction.

SECTION 7.13.  Waiver of Past Defaults.

        The Holders of a majority in principal amount of the Outstanding
Securities of any series may on behalf of the Holders of all the Securities of
such series waive any past default hereunder and its consequences, except a
default

                (1) in the payment of the principal of or premium, if any, or
        interest on any Security of such series or Coupon, if any, appertaining
        thereto, or in the payment of any sinking fund installment or analogous
        obligation with respect to Securities of such series, or

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

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

SECTION 7.14.  Undertaking for Costs.

        All parties to this Indenture agree, and each Holder of any Security or
Coupon, if any, appertaining thereto by his acceptance thereof shall be deemed
to have agreed, that any court may in its discretion require, in any suit for
the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs


<PAGE>   81
                                     - 71 -


of such suit, and that such court may in its discretion assess reasonable
costs, including reasonable attorneys' fees, against any party litigant in such
suit, having due regard to the merits and good faith of the claims or defenses
made by such party litigant; but the provisions of this Section shall not apply
to any suit instituted by the Trustee, to any suit instituted by any Holder of
any Security, or group of Holders of any Security, holding in the aggregate
more than 10% in principal amount of the Outstanding Securities of any series,
or to any suit instituted by any Holder of Securities or Coupons, if any,
appertaining thereto for the enforcement of the payment of the principal of,
premium, if any, or interest on any Security or Coupon, if any, appertaining
thereto on or after the respective Stated Maturities expressed in such Security
or Coupon (or, in the case of redemption or repayment, on or after the
Redemption Date or Repayment Date, as the case may be).

SECTION 7.15.  Waiver of Stay or Extension Laws.

        The Company and the Guarantor covenant (to the extent that they may
lawfully do so) that they 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 any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and the Company and
the Guarantor (to the extent that they may lawfully do so) hereby expressly
waive all benefit or advantage of any such law, and covenant that they will not
hinder, delay or impede the execution of any power herein granted to the
Trustee, but will suffer and permit the execution of every such power as though
no such law had been enacted.

SECTION 7.16.  Judgment Currency.

        If for the purpose of obtaining a judgment in any court with respect to
any obligation of the Company or the Guarantor hereunder or under any Security
or Coupon it shall become necessary to convert into any other currency or
currency unit any amount in the currency or currency unit due hereunder or
under such Security or Coupon, then such conversion shall be made at the
Conversion Rate as in effect on the date the Company or the Guarantor shall
make payment to any Person in satisfaction of such judgment. If pursuant to any
such judgment, conversion shall be made on a date other than the date payment
is made and there shall occur a change between such Conversion Rate and the
Conversion Rate as in effect on the date of payment, the Company and the
Guarantor agree to pay such additional amounts (if any) as may be necessary to
ensure that the amount paid is the amount in such other currency or currency
unit which, when converted at the


<PAGE>   82
                                     - 72 -


Conversion Rate as in effect on the date of payment or distribution, is the
amount then due hereunder or under such Security or Coupon. Any amount due from
the Company or the Guarantor under this Section 7.16 shall be due as a separate
debt and is not to be affected by or merged into any judgment being obtained
for any other sums due hereunder or in respect of any Security or Coupon. In no
event, however, shall the Company or the Guarantor be required to pay more in
the currency or currency unit due hereunder or under such Security or Coupon at
the Conversion Rate as in effect when payment is made than the amount of
currency or currency unit stated to be due hereunder or under such Security or
Coupon so that in any event the Company's and the Guarantor's obligations
hereunder or under such Security or Coupon will be effectively maintained as
obligations in such currency or currency unit.

        For purposes of this Section 7.16, "Conversion Rate" shall mean the
spot rate at which in accordance with normal banking procedures the currency or
currency unit into which an amount due hereunder or under any Security or
Coupon is to be converted could be purchased with the currency or currency unit
due hereunder or under any Security or Coupon from major banks located in New
York, London or any other principal market for such purchased currency or
currency unit.

                (3) to indemnify the Trustee for, and to hold it harmless
        against, any loss, liability or expense incurred without negligence or

a conflicting interest as defined in Section 310(b) of the Trust Indenture Act
with respect to the Securities of any series, there shall be excluded this

<PAGE>   87

supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of
condition so published. Neither the Company, the Guarantor, nor any person
directly or indirectly controlling, controlled by, or under common control with
the Company or the Guarantor shall serve as trustee for the Securities of any
series issued hereunder. In case at any time the Trustee for the Securities of
any series shall cease to be eligible in accordance with the provisions of this
Section, the Trustee shall resign immediately in the manner and with the effect
specified in Section 8.10.

SECTION 8.10.  Resignation and Removal; Appointment of Successor.

        (a) No resignation or removal of the Trustee for the Securities of any
series and no appointment of a successor Trustee pursuant to this Article shall
become effective until the acceptance of appointment by the successor Trustee
under Section 8.11.

        (b) The Trustee may resign with respect to one or more series at any
time by giving written notice thereof to the Company and the Guarantor. If an
instrument of acceptance by a successor Trustee 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.

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

        (d) It at any time

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

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

                (3) the Trustee shall become incapable of acting with respect
        to any series of Securities or shall be adjudged a


<PAGE>   88
                                     - 78 -


        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 or the Guarantor, by a Board
Resolution, may remove the Trustee with respect to such series or (ii) subject
to Section 7.14, 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 removal of the Trustee and the appointment of a successor Trustee with
respect to such series.

        (e) If the Trustee shall resign, be removed or become incapable of
acting with respect to any series of Securities, or if a vacancy shall occur in
the office of Trustee with respect to any series of Securities for any cause,
the Company or the Guarantor, by a Board Resolution, shall promptly appoint a
successor Trustee with respect to such series of Securities. If, within one
year after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to such series of Securities shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company, the Guarantor
and the retiring Trustee with respect to such series, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment, become the
successor Trustee with respect to such series and supersede the successor
Trustee appointed by the Company or the Guarantor. If no successor Trustee with
respect to such series shall have been so appointed by the Company, the
Guarantor or the Holders of Securities of such series and have accepted
appointment in the manner hereinafter provided, any Security Holder who has
been a bona fide Holder of a Security of such series for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor Trustee with
respect to such series.

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

Section 1.06, to the Holders of Securities, and Coupons, if any, appertaining
thereto, of such series. Each notice shall include the name of the successor
Trustee and the address of its Principal Corporate Trust Office.

SECTION 8.11.   Acceptance of Appointment by Successor.

        Every successor Trustee appointed hereunder shall execute, acknowledge
and deliver to the Company, the Guarantor and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective with respect to all series as to
which it is thereby resigning as Trustee and such successor Trustee, without
any further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the resigning Trustee with respect to all or any
such series; but, on request of the Company, the Guarantor or such successor
Trustee, such resigning Trustee shall, upon payment of its outstanding charges
and expenses, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee with respect
to all or any such series, and shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee
hereunder with respect to all or any such series, subject nevertheless to its
lien, if any, provided for in Section 8.07. Upon request of any such successor
Trustee, the Company and the Guarantor 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.

        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
Guarantor, the retiring Trustee and each successor Trustee with respect to the
Securities of any applicable series may execute and deliver an indenture
supplemental hereto containing 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 any series as to which the
retiring Trustee is not retiring shall continue to be vested in the retiring
Trustee, and adding to or changing 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 any such supplemental indenture shall constitute such Trustees
co-trustees of the same trust and that each such Trustee shall be Trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee.

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

SECTION 8.12.   Merger, Conversion, Consolidation or
                Succession to Business of Trustee.

        Any corporation into which the Trustee for the Securities of any series
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 8.13.   Preferential Collection of Claims
                Against Company and Guarantor.

        The Trustee shall comply with the requirements of Section 311 of the
Trust Indenture Act and any rules or regulations promulgated by the Commission
thereunder.

        the Guarantor for the benefit of the Holders of all or any series of
        Securities and the Coupons, if any, appertaining thereto (if such

                (4) to cure any ambiguity, to correct or supplement any
        provision herein which may be defective or inconsistent with any other
        provision herein, or to make any other provisions with respect to
        matters or questions arising under this Indenture provided such other
        provisions shall not adversely affect the interests of the Holders of
        Securities of any series then Outstanding and Coupons, if any,
        appertaining thereto;

                (5) to secure the Securities in accordance with the provisions

Trustee's own rights, duties or immunities under this Indenture or otherwise.

and in such event the Trustee shall return such deposited funds or obligations
as it is then holding to the Company or the Guarantor upon Company Request or
Guarantor Request, as applicable; and provided further that if the Trustee or
Paying Agent is unable to apply any money in accordance with Section 11.03 by
reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, then the
obligations of the Company and the Guarantor under this Indenture and the
Securities shall be revived and reinstated as though no deposit had occurred

Opinion of Counsel, an Officers' Certificate and, if appropriate under the
circumstances, an opinion of independent public accountants (and at the expense
of the Company), the Trustee shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture.

        Notwithstanding the satisfaction and discharge of this Indenture, any
obligations of the Company or the Guarantor under Sections 3.05, 3.06, 6.01,
8.07 and 8.10, any obligations of the Company or the Guarantor under Section

Agent (including the Company or Guarantor acting as its own Paying Agent) as
the Trustee may determine, to the Persons

Coupons, if any, appertaining thereto shall be paid in full and no such
payments or distributions to holders of such Senior Company Indebtedness to
which the Holders of the Subordinated Debt Securities and Coupons, if any,
appertaining thereto would be entitled except for the provisions hereof of
cash, property or securities otherwise distributable to the Senior Company
Indebtedness shall, as between the Company, its creditors, other than the

                                     - 94 -


or on account of the Subordinated Debt Securities and Coupons, if any,
appertaining thereto. It is understood that the provisions of this Article
Twelve (other than Sections 12.04, 12.05 and 12.06) are and are intended solely
for the purpose of defining the relative rights of the Holders of the
Subordinated Debt Securities and Coupons, if any, appertaining thereto, on the
one hand, and the holders of Senior Company Indebtedness, on the other hand.
Nothing contained in this Article Twelve or elsewhere in this Indenture, any
supplemental indenture issued pursuant to Section 3.01, or in the Subordinated
Debt Securities and Coupons, if any, appertaining thereto is intended to or
shall impair, as between the Company, its creditors, other than the holders of
Senior Company Indebtedness, and the Holders of the Subordinated Debt
Securities and Coupons, if any, appertaining thereto the obligation of the
Company, which is unconditional and absolute, to pay to the Holders of the
Subordinated Debt Securities and Coupons, if any, appertaining thereto the
principal of, premium, if any, and interest on the Subordinated Debt Securities
and Coupons, if any, appertaining thereto as and when the same shall become due
and payable in accordance with their terms or to affect the relative rights of
the Holders of the Subordinated Debt Securities and Coupons, if any,
appertaining thereto and creditors of the Company, other than the holders of
the Senior Company Indebtedness, nor shall anything herein or in the
Subordinated Debt Securities and Coupons, if any, appertaining thereto prevent
the Trustee or the Holder of any Subordinated Debt Securities and Coupons, if
any, appertaining thereto from exercising all remedies otherwise permitted by
applicable law upon Default under this Indenture, subject to the rights, if
any, under this Article Twelve of the holders of Senior Company 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 Twelve, the Trustee and the Holders of the
Subordinated Debt Securities and Coupons, if any, appertaining thereto shall be
entitled to rely upon any order or decree of a court of competent jurisdiction
in which such dissolution, winding up, liquidation or reorganization proceeding
is pending or upon a certificate of the liquidating trustee or agent or other
Person making any distribution to the Trustee or to the Holders of the
Subordinated Debt Securities and Coupons, if any, appertaining thereto for the
purpose of ascertaining the Persons entitled to participate in such
distribution, the holders of the Senior Company Indebtedness and other
indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article Twelve. In the absence of any such liquidating trustee, agent
or other person, the Trustee shall be entitled to rely upon a written notice by
a Person representing himself to be a holder of Senior Company Indebtedness (or
a trustee or representative on behalf of such holder) as evidence that such
Person is a holder of Senior Company


<PAGE>   105
                                     - 95 -


Indebtedness (or is such a trustee or representative). 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 Company Indebtedness,
to participate in any payment or distribution pursuant to this Article Twelve,
the Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of Senior Company Indebtedness
held by such Person, as to the extent to which such Person is entitled to
participation in such payment or distribution, and as to other facts pertinent
to the rights of such Person under this Article Twelve, and if such evidence is
not furnished, the Trustee may defer any payment to such Person pending
judicial determination as to the right of such Person to receive such payment.

        The obligation of the Company in respect to the Subordinated Debt
Securities and Coupons, if any, appertaining thereto shall rank on a parity
with any other obligations of the Company ranking on a parity with the
Subordinated Debt Securities, including the Company's 9-7/8% Subordinated Notes
Due 2001.

        With respect to the holders of Senior Company Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article, and no implied covenants or
obligations with respect to the holders of Senior Company Indebtedness shall be
read into this Article 12 against the Trustee; provided that nothing contained
herein shall derogate from covenants or obligations contained in this
Indenture, or any supplemental indenture issued pursuant to Section 3.01, with
respect to Senior Company Indebtedness that is issued as a series of Securities
under this Indenture. The Trustee, however, shall not be deemed to owe any
fiduciary duty to the holders of Senior Company Indebtedness by reason of the
execution of this Indenture, or any supplemental indenture issued pursuant to
Section 3.01, and shall not be liable to any such holders if it shall
mistakenly pay over or distribute to or on behalf of Holders of the
Subordinated Debt Securities and Coupons, if any, appertaining thereto or the
Company moneys or assets to which any holders of Senior Company Indebtedness
shall be entitled by virtue of this Article Twelve.

SECTION 12.03.  No Payment When Senior Company
                Indebtedness in Default.

        In the event and during the continuation of any default in the payment
of principal of, or premium, if any, or interest on, any Senior Company
Indebtedness, beyond any applicable period of grace, or in the event that any
event of default with respect to any Senior Company Indebtedness shall have
occurred and be continuing, or would occur as a result of the payment referred
to


<PAGE>   106
                                     - 96 -


hereinafter, permitting the holders of such Senior Company Indebtedness (or a
trustee on behalf of the holders thereof) to accelerate the maturity thereof,
then, unless and until such default or event of default shall have been cured
or waived or shall have ceased to exist, no payment or principal of or interest
on the Subordinated Debt Securities and Coupons, if any, appertaining thereto,
or in respect of any retirement, purchase or other acquisition of any of the
Subordinated Debt Securities and Coupons, if any, appertaining thereto, shall
be made by the Company.

SECTION 12.04.  Guarantees of Subordinated Debt Securities
                Subordinated to Senior Guarantor Indebtedness.

        The Guarantor, for itself, its successors and assigns, covenants and
agrees, and each Holder of Guarantees of Subordinated Debt Securities and
Coupons, if any, appertaining thereto by his acceptance thereof likewise
covenants and agrees, that the payment of the principal of and interest on each

thereto pursuant to the Guarantees 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 all Senior Guarantor Indebtedness.

SECTION 12.05.  Payments upon Dissolution of the Guarantor.

        Upon any distribution of assets of the Guarantor upon any dissolution,
winding up, liquidation or reorganization of the Guarantor, whether in
bankruptcy, insolvency, reorganization or receivership proceedings or upon an
assignment for the benefit of creditors or any other marshalling of the assets
and liabilities of the Guarantor or otherwise (subject to the power of a court
of competent jurisdiction to make other equitable provision reflecting the
rights conferred in this Indenture or any supplemental indenture issued
pursuant to Section 3.01 upon the Senior Guarantor Indebtedness and the holders
thereof with respect to the Guarantees of the Subordinated Debt Securities and
Coupons, if any, appertaining thereto and the Holders thereof by a lawful plan
of reorganization under applicable bankruptcy law),

                (i) the holders of all Senior Guarantor Indebtedness shall
        first be entitled to receive payment in full in accordance with the
        terms of such Senior Guarantor Indebtedness of the principal thereof,
        premium, if any, and the interest due thereon (including interest
        accruing subsequent to the commencement of any proceeding for the
        bankruptcy or reorganization of the Guarantor under any applicable
        bankruptcy, insolvency, or similar law now or


<PAGE>   107
                                     - 97 -


        hereafter in effect) before the Holders of the Guarantees of the
        Subordinated Debt Securities and Coupons, if any, appertaining thereto
        are entitled to receive any payment upon the principal of or premium,
        if any, or interest on indebtedness evidenced by the Subordinated Debt
        Securities and Coupons, if any, appertaining thereto pursuant to the
        Guarantees thereof;

                (ii) any payment or distribution of assets of the Guarantor of
        any kind or character, whether in cash, property or securities, to
        which the Holders of the Guarantees or the Subordinated Debt Securities
        and Coupons, if any, appertaining thereto or the Trustee would be
        entitled except for the provisions of this Article Twelve, including
        any such payment or distribution which may be payable or deliverable by
        reason of the payment of any other indebtedness of the Guarantor being
        subordinated to the payment of the Guarantees of the Subordinated Debt
        Securities and Coupons, if any, appertaining thereto, shall be paid by
        the liquidating trustee or agent or other person making such payment or
        distribution, whether a trustee in bankruptcy, a receiver or
        liquidating trustee or otherwise, directly to the holders of Senior
        Guarantor Indebtedness or their representative or representatives or to
        the trustee or trustees under any indenture under which any instruments
        evidencing any of such Senior Guarantor Indebtedness may have been
        issued, in accordance with the priorities then existing among holders
        of Senior Guarantor Indebtedness for payment of the aggregate amounts
        remaining unpaid on account of the principal, premium, if any, and
        interest (including interest accruing subsequent to the commencement of
        any proceeding for the bankruptcy or reorganization of the Company
        under any applicable bankruptcy, insolvency, or similar law now or
        hereafter in effect) on the Senior Guarantor Indebtedness held or
        represented by each, to the extent necessary to make payment in full of
        all Senior Guarantor Indebtedness remaining unpaid, after giving effect
        to any concurrent payment or distribution to the holders of such Senior
        Guarantor Indebtedness; it being understood that if the Holders of the
        Guarantees of the Subordinated Debt Securities and Coupons, if any,
        appertaining thereto shall fail to file a proper claim in the form
        required by any proceeding referred to in this subparagraph (ii) prior
        to 30 days before the expiration of the time to file such claim or
        claims, then the holders of Senior Guarantor Indebtedness are hereby
        authorized to file an appropriate claim or claims for and on behalf of
        the Holders of the Guarantees of the Subordinated Debt Securities and
        Coupons, if any, appertaining thereto, in the form required in any such

<PAGE>   108
                                     - 98 -


                (iii) in the event that, notwithstanding the foregoing, any
        payment or distribution of assets of the Guarantor of any kind or
        character, whether in cash, property or securities, including any such
        payment or distribution which may be payable or deliverable by reason
        of the payment of any other indebtedness of the Guarantor being
        subordinate to the payment of the Guarantees of the Subordinated Debt
        Securities and Coupons, if any, appertaining thereto shall be received
        by the Trustee or Holders of the Guarantees of the Subordinated Debt
        Securities and Coupons, if any, appertaining thereto before all Senior
        Guarantor Indebtedness is paid in full, such payment or distribution
        shall be paid over to the trustee in bankruptcy, receiver, liquidating
        trustee, custodian, assignee, agent or other Person making payment of
        assets of the Guarantor for all Senior Guarantor Indebtedness remaining
        unpaid until all such Senior Guarantor Indebtedness shall have been
        paid in full, after giving effect to any concurrent payment or
        distribution to the holders of such Senior Guarantor Indebtedness.

Subject to the payment in full of all Senior Guarantor Indebtedness, the
Holders of the Guarantees of the Subordinated Debt Securities and Coupons, if
any, appertaining thereto shall be subrogated to the rights of the holders of
Senior Guarantor Indebtedness to receive payments or distributions of cash,
property or securities of the Guarantor applicable to the Senior Guarantor
Indebtedness until the principal of and premium, if any, and interest on the
Guarantees of the Subordinated Debt Securities and Coupons, if any,
appertaining thereto shall be paid in full and no such payments or
distributions to holders of such Senior Guarantor Indebtedness to which the
Holders of the Guarantees of the Subordinated Debt Securities and Coupons, if
any, appertaining thereto would be entitled except for the provisions hereof of
cash, property or securities otherwise distributable to the Senior Guarantor
Indebtedness shall, as between the Guarantor, its creditors, other than the
holders of Senior Guarantor Indebtedness, and the Holders of the Guarantees of
the Subordinated Debt Securities and Coupons, if-any, appertaining thereto, be
deemed to be a payment by the Guarantor to or on account of the Guarantees of
the Subordinated Debt Securities and Coupons, if any, appertaining thereto. It
is understood that the provisions or this Article Twelve (other than Sections
12.01, 12.02 and 12.03) are and are intended solely for the purpose of defining
the relative rights of the Holders of the Guarantees of the Subordinated Debt
Securities and Coupons, if any, appertaining thereto, on the one hand, and the
holders of Senior Guarantor Indebtedness, on the other hand. Nothing contained
in this Article Twelve or elsewhere in this Indenture, any supplemental
indenture issued pursuant to Section 3.01, or in the Subordinated Debt
Securities and Coupons, if any, appertaining thereto or the

Guarantees thereof is intended to or shall impair, as between the Guarantor,
its creditors, other than the holders of Senior Guarantor Indebtedness, and the
Holders of the Guarantees of the Subordinated Debt Securities and Coupons, if
any, appertaining thereto the obligation of the Guarantor, which is
unconditional and absolute, to pay to the Holders of the Guarantees of the
Subordinated Debt Securities and Coupons, if any, appertaining thereto the
principal, premium, if any, and interest on the Subordinated Debt Securities
and Coupons, if any, appertaining thereto, pursuant to the Guarantees thereof,
as and when the same shall become due and payable in accordance with their
terms or to affect the relative rights of the Holders of the Guarantees of the
Subordinated Debt Securities and Coupons, if any, appertaining thereto and
creditors of the Guarantor, other than the holders of the Senior Guarantor
Indebtedness, nor shall anything herein or in the Subordinated Debt Securities
and Coupons, if any, appertaining thereto or the Guarantees thereof prevent the
Trustee or the Holder of any Guarantee of the Subordinated Debt Securities and
Coupons, if any, appertaining thereto from exercising all remedies otherwise
permitted by applicable law upon Default under this Indenture, subject to the
rights, if any, under this Article Twelve of the holders of Senior Guarantor
Indebtedness in respect of cash, property or securities of the Guarantor
received upon the exercise of any such remedy. Upon any payment or distribution
of assets of the Guarantor referred to in this Article Twelve, the Trustee and
the Holders of the Guarantees of the Subordinated Debt Securities and Coupons,
if any, appertaining thereto shall be entitled to rely upon any order or decree
of a court of competent jurisdiction in which such dissolution, winding up,
liquidation or reorganization proceeding is pending or upon a certificate of
the liquidating trustee or agent or other Person making any distribution to the
Trustee or to the Holders of the Guarantees of the Subordinated Debt Securities
and Coupons, if any, appertaining thereto for the purpose of ascertaining the
Persons entitled to participate in such distribution, the holders or the Senior
Guarantor Indebtedness and other indebtedness of the Guarantor, the amount
thereof or payable thereon, the amount or amounts paid or distributed thereon
and all other facts pertinent thereto or to this Article Twelve. In the absence
of any such liquidating trustee, agent or other person, the Trustee shall be
entitled to rely upon a written notice by a Person representing himself to be a
holder of Senior Guarantor Indebtedness (or a trustee or representative on
behalf of such holder) as evidence that such Person is a holder of Senior
Guarantor Indebtedness (or is such a trustee or representative). 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 Guarantor
Indebtedness, to participate in any payment or distribution pursuant to this
Article Twelve, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Guarantor


<PAGE>   110
                                    - 100 -


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

        The obligation of the Guarantor in respect to the Guarantees of the
Subordinated Debt Securities and Coupons, if any, appertaining thereto shall
rank on a parity with the Guarantor's 8-1/4% Convertible Subordinated
Debentures Due 2008, the Guarantor's Floating Rate Subordinated Notes Due 1997,
the Citizens Fidelity Corporation Convertible Subordinated Debentures Due 2005,

Guarantees of the Subordinated Debt Securities and Coupons, if any,
appertaining thereto.

        With respect to the holders of Senior Guarantor Indebtedness, the
Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article, and no implied
covenants or obligations with respect to the holders of Senior Guarantor
Indebtedness shall be read into this Article Twelve against the Trustee;
provided that nothing contained herein shall derogate from covenants or
obligations contained in this Indenture, or any supplemental indenture issued
pursuant to Section 3.01, with respect to Senior Guarantor Indebtedness that is
issued as a series of Securities under this Indenture. The Trustee, however,
shall not be deemed to owe any fiduciary duty to the holders of Senior
Guarantor Indebtedness by reason of the execution of this Indenture, or any
supplemental indenture issued pursuant to Section 3.01, and shall not be liable
to any such holders if it shall mistakenly pay over or distribute to or on
behalf of Holders of the Guarantees of the Subordinated Debt Securities and
Coupons, if any, appertaining thereto or the Guarantor moneys or assets to
which any holders of Senior Guarantor Indebtedness shall be entitled by virtue
of this Article Twelve.

SECTION 12.06.  No Payment When Senior Guarantor
                Indebtedness in Default.

        In the event and during the continuation of any default in the payment
of principal of, or premium, if any, or interest on, any Senior Guarantor
Indebtedness, beyond any applicable period of grace, or in the event that any

Holders of the Guarantees of the Subordinated Debt Securities and Coupons, if
any, appertaining thereto, the obligations of the Company or Guarantor, as the
case may be, to make, or prevent the Company or Guarantor from making, at any
time except as provided in Sections 12.02, 12.03, 12.05 and 12.06, payments of
principal, premium, if any, or interest (including interest accruing subsequent
to the commencement of any proceeding for the bankruptcy or reorganization of
the Company or Guarantor under any applicable bankruptcy, insolvency, or
similar law now or hereafter in effect) on the Subordinated Debt Securities and
Coupons, if any, appertaining thereto, and the Guarantees thereof as and when

or such Holders may determine the time and the place in the Borough of
Manhattan or other Place of Payment for such meeting and may call such meeting

        The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting unless the meeting shall have been called by the

provided in Section 14.03, in which case the Company, the Guarantor or the
Holders calling the meeting as the case may be, shall in like manner appoint a

Holders, the presence of persons holding or representing Securities with

present, the persons holding or representing a majority in aggregate principal
amount of such Securities represented at the meeting may adjourn such meeting
with the same effect, for all intents and purposes, as though a quorum had been
present. Any meeting of Holders of Securities with respect to which a meeting
was duly called pursuant to the provisions of Section 14.02 or Section 14.03
may be adjourned from time to time by a majority of such Holders present,
whether or not constituting a quorum, and the meeting may be held as so
adjourned without further notice.

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

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

of the Securities voting in favor of or against any resolution. The record
shall be signed and verified by the affidavits of the permanent chairman and
secretary of the meeting and one of the triplicates shall be delivered to each
of the Company and the Guarantor and the other to the Trustee to be preserved
by the Trustee.

        Any record so signed and verified shall be conclusive evidence of the
matters therein stated.

SECTION 14.07.  No Delay of Rights by Meeting.

        Nothing contained in this Article Fourteen shall be deemed or construed
to authorize or permit by reason of any call of a meeting of Holders or any
rights expressly or impliedly conferred hereunder to make such call, any
hindrance or delay in the exercise of any right or rights conferred upon or
reserved to the Trustee or to the Holders under any of the provisions of this

undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article, and no implied covenants or
obligations with respect to the holders of Senior Company Indebtedness shall be

"Securities"), issued and to be issued in one or more series under an
Indenture, dated as of December 1, 1991, among the Company, PNC Financial Corp
(now known as PNC Bank Corp.) ("Guarantor") and Manufacturers Hanover Trust
Company, as Trustee (herein called the "Trustee," which term includes any
successor trustee under the Indenture) as amended by a Supplemental Indenture
dated as of February 15, 1993 by and among the Company, PNC Bank Corp.
(formerly known as PNC Financial Corp) ("Guarantor") and Chemical Bank
(successor by merger to Manufacturers Hanover Trust Company and now known as
The Chase Manhattan Bank) ("Trustee") (such Indenture as amended being herein
called the "Indenture"), to which Indenture and all indentures supplemental
thereto reference is hereby made for a statement of the respective rights,
limitations of rights, duties and immunities thereunder of the Company, the
Trustee and the Holders of the Securities and of the terms upon which the
Securities are, and are to be, authenticated and delivered. This Security is
one of the series designated above, limited (except as provided in the
Indenture) in aggregate principal amount to $_________________.

       The Securities of this series are not redeemable prior to their Stated
Maturity. The Notes of this series are not subject to any sinking fund.

       If an Event of Default (as defined in the Indenture) with respect to
Securities of this series shall occur and be continuing, the principal of the
Securities of this series may be declared due and payable in the manner and
with the effect provided in the Indenture.

       The indebtedness of the Company evidenced by the Securities of this
series, including the principal thereof and interest thereon, is, to the extent
and in the manner set forth in the Indenture, subordinate and junior in right
of payment to its obligations to holders of Senior Company Indebtedness (as
defined in the Indenture) and shall rank pari passu in right of payment with
each other and with Existing Company Subordinated Indebtedness (as defined in
said Indenture), subject to the obligations of the holders of the Securities to
pay over any Excess Proceeds to creditors in respect of Other Company
Obligations, as provided in the Indenture, and each Holder of Securities, by
the acceptance hereof, agrees to and shall be bound by such provisions of the
Indenture. The indebtedness of the Company evidenced by

                                     - 4 -

the Securities of this series, including the principal thereof and interest
thereon, also shall rank pari passu in right of payment with the Company's
________% Subordinated Notes Due _______, ______% Subordinated Notes Due
_______ and ____% Subordinated Notes Due ____, the holders of which are also
obligated to pay over any Excess Proceeds to creditors in respect of Other
Company Obligations, as provided in the Indenture.

       The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the Guarantor and the rights of the holders of the Securities of
any series under the Indenture at any time by the Company, the Guarantor and
the Trustee with the consent of the holders of a majority in principal amount
of the outstanding Securities of all series (voting as one class) to be
affected by such amendment or modification. The Indenture also contains
provisions permitting the holders of specified percentages in principal amount
of the Outstanding Securities of any series, on behalf of the holders of all
Securities of such series, to waive compliance by the Company or the Guarantor
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the holder of
this Security shall be conclusive and binding upon such holder and upon all
future holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

       No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of and interest on this
Security at the times, place and rate, and in the coin or currency, herein
prescribed.

       As provided in the Indenture and subject to certain limitations therein
set forth and to the limitations set forth in the legend on the first page of
this Security, the transfer of this Security is registrable in the Security
Register, upon due presentment of this Security for registration of transfer at
the office or agency of the Company in the Borough of Manhattan, The City of
New York, duly endorsed by, or accompanied by a written instrument of


<PAGE>   5



                                     - 5 -

transfer in form satisfactory to the Company duly executed by, the registered
holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Securities of this series, of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or
transferees.

       The Securities of this series are issuable only in registered form
without coupons in denominations of $1,000 and any integral multiple thereof.
As provided in the Indenture and subject to certain limitations therein set
forth, Securities of this series are exchangeable for a like aggregate
principal amount of Securities of this series of a different authorized
denomination, as requested by the Holder surrendering the same.

       No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

       Prior to due presentment of this Security for registration of transfer,
the Company, the Guarantor, the Trustee and any agent of the Company, the
Guarantor or the Trustee may treat the Person in whose name this Security is
registered as the owner hereof for all purposes, whether or not this Security
be overdue, and neither the Company, the Guarantor, the Trustee nor any such
agent shall be affected by notice to the contrary.

       This Security is a global security. Accordingly, unless and until it is
exchanged in whole or in part for individual certificates evidencing the
Securities represented hereby, this Security may not be transferred except as a
whole by The Depository Trust Company (the "Depositary") to a nominee of such
Depositary or by a nominee of such Depositary or by the Depositary or any
nominee to a successor Depositary or any nominee of such successor.  Ownership
of beneficial interests in this Security will be shown on, and the transfer of
that ownership will be effected only through, records maintained by the
applicable Depositary or its nominee (with respect to interest of persons that
have accounts with the Depositary ("Participants") and the records of
Participants (with respect to interests of persons other than Participants)).
The laws of some states require that certain purchasers of securities take
physical

                                     - 6 -

delivery of such securities in definitive form. Such limits and such laws may
impair the ability to transfer beneficial interests in this Security. Except as
provided below, owners of beneficial interests in this Security will not be
entitled to have any individual certificates and will not be considered the
owners or Holders thereof under the Indenture.

       Neither the Company, the Trustee, any Issuing and Paying Agent or any
Security Registrar will have any responsibility or liability for any aspect of
the records relating to or payments made on account of beneficial ownership
interests in this Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

       If the Depositary is at any time unwilling, unable or ineligible to
continue as Depositary and a successor Depositary is not appointed by the
Company within 90 days, the Company will issue individual certificates
evidencing the Securities represented hereby in definitive form in exchange for
this Security. In addition, the Company may at any time and in its sole
discretion determine not to have any Securities represented by one or more
global securities and, in such event, will issue individual certificates
evidencing Securities in definitive form in exchange for this Security. In any
such instance, an owner of a beneficial interest in a Security will be entitled
to physical delivery in certificated form of Securities equal in principal
amount to such beneficial interest and to have such Securities registered in
its name. Securities so issued in certificated form will be issued in
denominations of $1,000 and any integral multiple thereof and will be issued in
registered form only, without coupons.

       The Indenture contains provisions setting forth certain conditions to
the institution of proceedings by the holders of Securities with respect to the
Indenture or for any remedy under the Indenture.

       All terms used in this Security which are defined in the Indenture shall
have the meanings assigned to them in the Indenture.

       IN WITNESS WHEREOF, PNC Funding Corp has caused this Note to be signed
in its name by its Chairman of the Board, President or any Executive or Senior
Vice President, and by its Secretary or an Assistant

Board of Directors
PNC Bank Corp.
One PNC Plaza
249 Fifth Avenue
Pittsburgh, Pennsylvania  15222-2707

Gentlemen:

This opinion is issued in connection with the Registration Statement on Form
S-3 (the "Registration Statement") of PNC Bank Corp. (the "Corporation") and
PNC Funding Corp ("PNC Funding") to be filed with the Securities and Exchange
Commission (the "Commission"), relating to the registration under the
Securities Act of 1933, as amended (the "Securities Act"), of unsecured debt
securities of PNC Funding ("Debt Securities"), guaranteed by the Corporation
(the "Guarantees"), shares of the Corporation's common stock, par value $5.00
per share ("Common Stock"), and shares of the Corporation's preferred stock,
par value $1.00 per share ("Preferred Stock"), with a proposed maximum offering
price for such Debt Securities, Common Stock and Preferred Stock of
$1,300,000,000, plus an undetermined number of shares of Common Stock issuable
upon conversion of the Preferred Stock to the extent any of such shares of
Preferred Stock are by their terms convertible into Common Stock, and an
undetermined number of shares of Preferred Stock in the form of shares
("Depositary Shares") to be evidenced by depositary receipts to be issued
pursuant to a Deposit Agreement (in the form filed as Exhibit 4.5 to the
Registration Statement, the "Deposit Agreement"). The Common Stock, the
Preferred Stock and the Depositary Shares are collectively referred to as the
"Registered Equity Securities". The Prospectus contained in the Registration
Statement is referred to as the "Basic Prospectus". The term "Total Prospectus"
refers to the Basic Prospectus and the applicable supplement to such Basic
Prospectus with respect to a particular offering of Debt Securities or
Registered Equity Securities.

As Senior Counsel to the Corporation, I have examined (1) the Articles of
Incorporation and Bylaws, each as amended to date, of the Corporation; (2) the
Articles of Incorporation and By-laws, each as amended to date, of PNC Funding;
(3) the Indenture dated as of December 1, 1991, as amended and supplemented by
the Supplemental Indenture dated as of February 15, 1993, filed as Exhibit 4.7
and Exhibit 4.8, respectively (as amended, the "Indenture"), pursuant to which
the Debt Securities and related Guarantees will be issued; (4) the Deposit
Agreement; (5) the Registration Statement, including the Basic Prospectus and
the Exhibits being filed with it and as of this date


<PAGE>   2


Board of Directors
PNC Bank Corp.
Page 2

incorporated therein by reference; (6) the resolutions adopted by the
Corporation's Board of Directors at a meeting held on August 21, 1997; and (7)
the Written Action of the Board of Directors of PNC Funding dated as of August
21, 1997. I have also examined such records, certificates and other documents
relating to the Corporation and PNC Funding that I have considered necessary or
appropriate for the purposes of this opinion.

In making such examination and rendering the opinions set forth below, I have
assumed: (i) the genuineness and authenticity of all signatures on original
documents; (ii) the authenticity of all documents submitted to me as originals;
and (iii) the conformity of originals of all documents submitted to me as
certified, telecopied, photostated or reproduced copies and the authenticity of
all originals of such documents.

I am admitted to practice law in the Commonwealth of Pennsylvania and do not
purport to be an expert on or to express any opinion on any laws other than the
laws of the Commonwealth of Pennsylvania and the federal securities laws of the
United States of America. This opinion speaks as of today's date and is limited
to present statutes, regulations and judicial interpretations. In rendering
this opinion, I assume no obligation to revise or supplement this opinion
should the present laws be changed by legislative or regulatory action,
judicial decision or otherwise or should the agreements or other documents (or
forms thereof) that I have examined in connection with this opinion hereafter
be changed.

With respect to any Common Stock held as treasury shares that may be sold, my
opinion is also subject to the condition that such shares had been validly
issued before they were reacquired by the Corporation and became treasury
shares. With respect to my opinion relating to Depositary Shares, I have
assumed that the Deposit Agreement has been duly authorized, executed and
delivered by the Corporation and the applicable depositary, and that the
depositary receipts have been duly countersigned by a registrar and the
applicable depositary in accordance with the Deposit Agreement. With respect to
each of the Common Stock and Preferred Stock, I have assumed that certificates
evidencing such Registered Equity Securities have been duly countersigned by
the applicable registrar and transfer agent.

Based upon the foregoing, and subject to the qualifications and limitations
stated herein, I am of the opinion that:

(1) When the Registration Statement has become effective in accordance with
applicable law, appropriate corporate action is taken with respect to
Registered Equity Securities being issued and sold, and the Registered Equity
Securities have been issued and sold upon the terms and conditions set forth in
the Registration Statement and the Total Prospectus, with payment having
been made therefor, then such Registered Equity Securities will be validly
issued, fully paid and nonassessable. To the extent such Registered Equity
Securities are shares of Preferred Stock that are convertible into Common
Stock, when such shares are converted pursuant to and in accordance with


<PAGE>   3


Board of Directors
PNC Bank Corp.
Page 2

the terms of the Preferred Stock, the shares of Common Stock so converted will
be validly issued, fully paid and nonassessable.

(2) When the Registration Statement has become effective in accordance with
applicable law, appropriate corporate action is taken with respect to the Debt
Securities and related Guarantees being issued and sold, and the Debt
Securities and related Guarantees are authenticated and issued pursuant to and
in accordance with the terms and conditions set forth in the Indenture and
delivered and sold as set forth in the Registration Statement and the Total
Prospectus, with payment having been made therefor, then such Debt Securities
and Guarantees will constitute valid and legally binding obligations of PNC
Funding and the Corporation, respectively, except as enforceability is limited
by applicable bankruptcy, insolvency, receivership, readjustment of debt,
fraudulent conveyance, reorganization, moratorium and other laws relating to or
affecting creditors' rights generally or general equitable principles, whether
considered in a proceeding in equity or at law.

I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to me under the caption "Legal
Opinions" in the Prospectus included in Part I of the Registration Statement.
In giving such consent, I do not thereby admit that I come within the category
of persons whose consent is required under Section 7 of the Securities Act or
the rules and regulations of the Commission thereunder.

Very truly yours,

/s/ MELANIE S. CIBIK
