(Cover page continued)
the Trust C Issuer (the "Trust C Common Securities" and, collectively with the
Trust C Capital Securities, the "Trust C Securities"). Bankers Trust Company is
the Property Trustee of the Trust C Issuer. The Trust C Issuer exists for the
sole purpose of issuing the Trust C Capital Securities and the Trust C Common
Securities and investing the proceeds thereof in approximately $206.2 million
aggregate principal amount of Floating Rate Junior Subordinated Deferrable
Interest Debentures (the "Trust C Subordinated Debentures") to be issued by the
Corporation. The Trust C Subordinated Debentures will mature on June 1, 2028,
which date may be shortened (such date, as it may be shortened, the "Stated
Maturity") to a date not earlier than June 1, 2008 if certain conditions are met
(including the Corporation having received the prior approval of the Board of
Governors of the Federal Reserve System (the "Federal Reserve"), if then
required under applicable capital guidelines or policies of the Federal Reserve
(such shortening of the maturity date, the "Maturity Adjustment")). The Trust C
Capital Securities will have a preference under certain circumstances with
respect to cash distributions and amounts payable on liquidation or redemption
over the Trust C Common Securities. See "Description of Capital
Securities--Subordination of Common Securities" in the accompanying Prospectus.
 
     Holders of the Trust C Capital Securities will be entitled to receive
cumulative cash distributions accruing from the date of original issuance and
payable quarterly in arrears on the first day of March, June, September and
December of each year, commencing September 1, 1998, at a variable annual rate
equal to 3-Month LIBOR (as defined herein) plus a spread of 0.57% (the
"Distribution Rate") in respect of the Liquidation Amount (as defined in the
accompanying Prospectus) of $1,000 per Trust C Capital Security
("Distributions"). Subject to certain exceptions, as described herein, the
Corporation has the right to defer payment of interest on the Trust C
Subordinated Debentures at any time or from time to time for a period not
exceeding 20 consecutive quarterly periods with respect to each deferral period
(each, an "Extension Period"), provided that no Extension Period may extend
beyond the Stated Maturity of the Trust C Subordinated Debentures. Upon the
termination of any such Extension Period and the payment of all interest then
accrued and unpaid (together with interest thereon at the Interest Rate (as
defined herein), compounded quarterly, to the extent permitted by applicable
law), the Corporation may elect to begin a new Extension Period subject to the
requirements set forth herein. If interest payments on the Trust C Subordinated
Debentures are so deferred, Distributions on the Trust C Capital Securities will
also be deferred and the Corporation will not be permitted, subject to certain
exceptions described herein, to declare or pay any cash distributions with
respect to the Corporation's capital stock or debt securities that rank pari
passu with or junior to the Trust C Subordinated Debentures (including the
8.315% Junior Subordinated Debentures (the "8.315% Subordinated Debentures") of
the Corporation issued on May 19, 1997). During an Extension Period, interest on
the Trust C Subordinated Debentures will continue to accrue (and the amount of
Distributions to which holders of the Trust C Capital Securities are entitled
will accumulate), at the Interest Rate, compounded quarterly from the relevant
payment date for such interest, and holders of Trust C Capital Securities will
be required to accrue interest income for United States federal income tax
purposes. See "Certain Terms of Trust C Subordinated Debentures--Option to Defer
Interest Payments" and "Certain Federal Income Tax Consequences--US
Holders--Interest Income and Original Issue Discount."
 
     The Trust C Subordinated Debentures are unsecured and subordinated to all
Senior Indebtedness (as defined in the accompanying Prospectus). Because the
Corporation is a holding company, the right of the Corporation to participate in
any distribution of assets of any subsidiary, including PNC Bank, National
Association ("PNC Bank"), upon such subsidiary's liquidation or reorganization
or otherwise, is subject to the prior claims of creditors of that subsidiary,
except to the extent that the Corporation may itself be recognized as a creditor
of that subsidiary. Accordingly, the Trust C Subordinated Debentures (and
therefore the Trust C Capital Securities) will be effectively subordinated to
all existing and future liabilities of the Corporation's subsidiaries, and
holders
 
                                       S-2

(Cover page continued)
 
thereof should only look to the assets of the Corporation for payments on the
Trust C Subordinated Debentures. See "Description of Junior Subordinated
Debentures--Subordination" in the accompanying Prospectus.
 
     The Corporation has, through the Trust C Guarantee, the Trust C Trust
Agreement, the Trust C Subordinated Debentures and the Indenture (each as
defined herein), taken together, fully, irrevocably and unconditionally
guaranteed all of the Trust C Issuer's obligations under the Trust C Capital
Securities as described below. See "Relationship Among the Capital Securities,
the Corresponding Junior Subordinated Debentures and the Guarantees--Full and
Unconditional Guarantee" in the accompanying Prospectus. The Trust C Guarantee
of the Corporation (the "Trust C Guarantee") guarantees the payment of
Distributions and payments on liquidation of the Trust C Issuer or redemption of
the Trust C Capital Securities, but only in each case to the extent of funds
held by the Trust C Issuer, as described herein. See "Description of Guarantees"
in the accompanying Prospectus. If the Corporation does not make interest
payments on the Trust C Subordinated Debentures held by the Trust C Issuer, the
Trust C Issuer will have insufficient funds to pay Distributions on the Trust C
Capital Securities. The Trust C Guarantee does not cover payment of
Distributions when the Trust C Issuer has insufficient funds to pay such
Distributions. In such event, a holder of Trust C Capital Securities may
institute a legal proceeding directly against the Corporation pursuant to the
terms of the Indenture to enforce payment of amounts equal to such Distributions
to such holder. See "Description of Junior Subordinated Debentures--Enforcement
of Certain Rights by Holders of Capital Securities" in the accompanying
Prospectus. The obligations of the Corporation under the Trust C Guarantee are
subordinate and junior in right of payment to all Senior Indebtedness of the
Corporation.
 
     The Trust C Capital Securities are subject to mandatory redemption in
whole, or in part, upon repayment of the Trust C Subordinated Debentures at
their Stated Maturity or their earlier redemption. The Trust C Subordinated
Debentures are redeemable prior to maturity at the option of the Corporation (i)
on or after June 1, 2008, in whole at any time or in part from time to time, in
each case, on an Interest Payment Date (as defined herein), or (ii) in whole,
but not in part, at any time within 90 days following the occurrence and during
the continuation of a Tax Event, Investment Company Event or Capital Treatment
Event (each as defined herein), in each case at a redemption price set forth
herein, which includes the accrued and unpaid interest on the Trust C
Subordinated Debentures so redeemed to the date fixed for redemption. The
ability of the Corporation to exercise its rights to redeem the Trust C
Subordinated Debentures or to cause the redemption of the Trust C Capital
Securities prior to the Stated Maturity may be subject to prior regulatory
approval by the Federal Reserve, if then required under applicable capital
guidelines or policies.
 
     The holders of the outstanding Trust C Common Securities will have the
right at any time to terminate the Trust C Issuer, subject to the Corporation
having received prior approval of the Federal Reserve to do so if then required
under applicable capital guidelines or policies. See "Certain Terms of Trust C
Capital Securities--Liquidation of Trust C Issuer and Distribution of Trust C
Subordinated Debentures to Holders." In the event of the termination of the
Trust C Issuer, after satisfaction of liabilities to creditors of the Trust C
Issuer as required by applicable law, the holders of the Trust C Capital
Securities will be entitled to receive a Liquidation Amount of $1,000 per Trust
C Capital Security plus accumulated and unpaid Distributions thereon to the date
of payment, which may be in the form of a distribution of such amount in Trust C
Subordinated Debentures in exchange therefor, subject to certain exceptions. See
"Description of Capital Securities--Liquidation Distribution Upon Termination"
in the accompanying Prospectus.
 
     The Trust C Capital Securities will be represented by one or more global
certificates registered in the name of The Depository Trust Corporation ("DTC")
or its nominee. Beneficial interests in the Trust C Capital Securities will be
shown on, and transfers thereof will be effected only through, records
maintained by DTC and its participants. Except as described in the accompanying
Prospectus, Trust C Capital Securities in certificated form will not be issued
in exchange for the global certificates. See "Certain Terms of Trust C Capital
Securities--Registration of Trust C Capital Securities.

                                  RISK FACTORS
 
     Prospective purchasers of the Trust C Capital Securities should carefully
review the information contained or incorporated by reference in this Prospectus
Supplement and should particularly consider the following matters. Certain
statements in this Prospectus Supplement and documents incorporated herein by
reference are forward-looking and are identified by the use of forward-looking
words or phrases such as "intended," "will be positioned," "expects," is or are
"expected," "anticipates," and "anticipated." These forward-looking statements
are based on the Corporation's current expectations. To the extent any of the
information contained or incorporated by reference in this Prospectus Supplement
constitutes a "forward-looking statement" as defined in Section 27A(i)(1) of the
Securities Act of 1933, as amended, the "Securities Act"), the risk factors set
forth below are cautionary statements identifying important factors that could
cause actual results to differ materially from those in the forward-looking
statement.
 
RANKING OF SUBORDINATED OBLIGATIONS UNDER THE TRUST C GUARANTEE AND THE TRUST C
SUBORDINATED DEBENTURES
 
     The obligations of the Corporation under the Trust C Guarantee issued by
the Corporation for the benefit of the holders of Trust C Capital Securities and
under the Trust C Subordinated Debentures are subordinate and junior in right of
payment to all Senior Indebtedness. At March 31, 1998, the Senior Indebtedness
of the Corporation aggregated approximately $2.0 billion. None of the Indenture,
the Trust C Guarantee or the Trust C Trust Agreement places any limitation on
the amount of secured or unsecured debt, including Senior Indebtedness, that may
be incurred by the Corporation. See "Description of Guarantees--Status of the
Guarantees" and "Description of Junior Subordinated Debentures--Subordination"
in the accompanying Prospectus.
 
     The ability of the Trust C Issuer to pay amounts due on the Trust C Capital
Securities is solely dependent upon the Corporation's making payments on the
Trust C Subordinated Debentures as and when required.
 
STATUS OF THE CORPORATION AS A BANK HOLDING COMPANY
 
     The Corporation is a legal entity separate and distinct from its subsidiary
banks (the "Banks") and its other subsidiaries, although the principal source of
the Corporation's cash revenues is dividends from the Banks. The right of the
Corporation to participate in the assets of any subsidiary upon the latter's
liquidation, reorganization or otherwise (and thus the ability of the holders of
Trust C Capital Securities to benefit indirectly from any such distribution)
will be subject to the claims of the subsidiaries' creditors, which will take
priority except to the extent that the Corporation may itself be a creditor with
a recognized claim. As of March 31, 1998, the Corporation's subsidiaries had
indebtedness and other liabilities of approximately $65.151 billion (including
deposits).
 
                                       S-5
<PAGE>   6
 
     Payment of dividends by the Banks is restricted by various legal and
regulatory limitations. At March 31, 1998, approximately $732.3 million was
available for payment of dividends to the Corporation from banking subsidiaries
without prior regulatory approval.
 
     The Banks are also subject to restrictions under federal law which limit
the transfer of funds by any of the Banks to the Corporation and its nonbanking
subsidiaries, whether in the form of loans, extensions of credit, investments,
asset purchases or otherwise. Such transfers by any Bank to the Corporation or
any of the Corporation's nonbanking subsidiaries are limited in amount to 10% of
such Bank's capital and surplus and, with respect to the Corporation and all
such nonbanking subsidiaries, to an aggregate of 20% of such Bank's capital and
surplus. Furthermore, such loans and extensions of credit are required to be
secured in specified amounts. See "Supervision, Regulation and Other Matters" in
the accompanying Prospectus.
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD; TAX CONSEQUENCES
 
     So long as no Event of Default (as defined in the Indenture) has occurred
and is continuing with respect to the Trust C Subordinated Debentures (a
"Debenture Event of Default"), the Corporation has the right under the Indenture
to defer the payment of interest on the Trust C Subordinated Debentures at any
time or from time to time for a period not exceeding 20 consecutive quarterly
periods with respect to each Extension Period, provided that no Extension Period
may extend beyond the Stated Maturity of the Trust C Subordinated Debentures.
See "Description of Junior Subordinated Debentures--Debenture Events of Default"
in the accompanying Prospectus. As a consequence of any such deferral, quarterly
Distributions on the Trust C Capital Securities by the Trust C Issuer will be
deferred during any such Extension Period. Distributions to which holders of the
Trust C Capital Securities are entitled will accumulate additional Distributions
thereon during any Extension Period at a rate equal to the Distribution Rate,
compounded quarterly from the relevant payment date for such Distributions,
computed on the basis of a 360-day year of twelve 30-day months and the actual
days elapsed in a partial month in such period. The term "Distribution" as used
herein shall include any such additional Distributions. During any such
Extension Period, the Corporation may not (i) declare or pay any dividends or
distributions on, or redeem, purchase, acquire or make a liquidation payment
with respect to, any of the Corporation's capital stock or (ii) make any payment
of principal of or interest or premium, if any, on or repay, repurchase or
redeem any debt securities of the Corporation that rank pari passu in all
respects with or junior in interest to the Trust C Subordinated Debentures
(other than (a) repurchases, redemptions or other acquisitions of shares of
capital stock of the Corporation in connection with any employment contract,
benefit plan or other similar arrangement with or for the benefit of any one or
more employees, officers, directors or consultants, in connection with a
dividend reinvestment or stockholder stock purchase plan or in connection with
the issuance of capital stock of the Corporation (or securities convertible into
or exercisable for such capital stock) as consideration in an acquisition
transaction entered into prior to the applicable Extension Period, (b) as a
result of an exchange or conversion of any class or series of the Corporation's
capital stock (or any capital stock of a subsidiary of the Corporation) for any
class or series of the Corporation's capital stock or any class or series of the
Corporation's indebtedness for any class or series of the Corporation's capital
stock, (c) the purchase of fractional interests in shares of the Corporation's
capital stock pursuant to the conversion or exchange provisions of such capital
stock or the security being converted or exchanged, (d) any declaration of a
dividend in connection with any stockholder's rights plan, or the issuance of
rights, stock or other property under any stockholder's rights plan, or the
redemption or repurchase of rights pursuant thereto, or (e) any dividend in the
form of stock, warrants, options or other rights where the dividend stock or the
stock issuable upon exercise of such warrants, options or other rights is the
same stock as that on which the dividend is being paid or ranks pari passu with
or junior to such stock). Prior to the termination of any such Extension Period,
the Corporation may further defer the payment of interest, provided that no
Extension Period may exceed 20 consecutive quarterly periods or extend beyond
the Stated Maturity of the Trust C Subordinated Debentures. Upon the termination
of any Extension Period and the payment of all interest then accrued and unpaid
(together with interest thereon at a rate equal to the Interest Rate, compounded
quarterly, to the extent permitted by applicable law), the Corporation may elect
to begin a new Extension Period subject to the above conditions. No interest
shall be due and payable during an Extension Period, except at the end thereof.
The Corporation must give the holders of the Trust C Subordinated Debentures and
the Debenture Trustee notice of its election of such Extension Period at least
one Business Day (as defined in the accompanying Prospectus) prior to the
earlier of (i) the next succeeding date on which the
                                       S-6
<PAGE>   7
 
Distributions on the Trust C Capital Securities would have been payable but for
the election to begin such Extension Period and (ii) the date on which the
Property Trustee is required to give notice to holders of the Trust C Capital
Securities of the record date or the date such Distributions are payable, but in
any event not less than one Business Day prior to such record date. The Property
Trustee will give notice of the Corporation's election to begin a new Extension
Period to the holders of the Trust C Capital Securities. Subject to the
foregoing, there is no limitation on the number of times that the Corporation
may elect to begin an Extension Period. See "Certain Terms of Trust C Capital
Securities--Distributions" and "Certain Terms of Trust C Subordinated
Debentures--Option to Defer Interest Payments."
 
     Should an Extension Period occur, a holder of Trust C Capital Securities
will continue to accrue income (in the form of original issue discount) for
United States federal income tax purposes in respect of its pro rata share of
the Trust C Subordinated Debentures held by the Trust C Issuer (which will
include a holder's pro rata share of both the stated interest and de minimis
original issue discount, if any, on the Trust C Subordinated Debentures). As a
result, a holder of Trust C Capital Securities will include such interest income
in gross income for United States federal income tax purposes in advance of the
receipt of cash attributable to such original issue discount interest income,
and will not receive the cash related to such income from the Trust C Issuer if
the holder disposes of the Trust C Capital Securities prior to the record date
for the payment of Distributions with respect to such Extension Period. See
"Certain Federal Income Tax Consequences--US Holders--Interest Income and
Original Issue Discount" and "--Sales or Redemption of Trust C Capital
Securities."
 
     The Corporation has no current intention of exercising its right to defer
payments of interest by extending the interest payment period on the Trust C
Subordinated Debentures. However, should the Corporation elect to exercise such
right in the future, the market price of the Trust C Capital Securities is
likely to be affected. A holder that disposes of its Trust C Capital Securities
during an Extension Period, therefore, might not receive the same return on its
investment as a holder that continues to hold its Trust C Capital Securities. In
addition, as a result of the existence of the Corporation's right to defer
interest payments, the market price of the Trust C Capital Securities (which
represent preferred undivided beneficial interests in the assets of the Trust C
Issuer) may be more volatile than the market prices of other securities on which
original issue discount accrues that are not subject to such deferrals.
 
TAX EVENT, INVESTMENT COMPANY EVENT OR CAPITAL TREATMENT EVENT REDEMPTION
 
     Upon the occurrence and during the continuation of a Tax Event, Investment
Company Event or Capital Treatment Event, the Corporation has the right to
redeem the Trust C Subordinated Debentures in whole, but not in part, at any
time within 90 days following the occurrence and during the continuation of such
Tax Event, Investment Company Event or Capital Treatment Event and thereby cause
a mandatory redemption of the Trust C Capital Securities and Trust C Common
Securities. Any such redemption shall be at a price equal to the Liquidation
Amount of the Trust C Capital Securities and Trust C Common Securities,
respectively, together with accumulated Distributions to but excluding the date
fixed for redemption. The ability of the Corporation to exercise its rights to
redeem the Trust C Subordinated Debentures prior to the Stated Maturity may be
subject to prior approval by the Federal Reserve, if then required under
applicable Federal Reserve capital guidelines or policies. See "Certain Terms of
Trust C Subordinated Debentures--Redemption" and "Description of Capital
Securities--Redemption or Exchange" in the accompanying Prospectus.
 
     A "Tax Event" means the receipt by the Trust C Issuer of an opinion of
counsel to the Corporation experienced in such matters to the effect that, as a
result of any amendment to, or change (including any announced prospective
change) in, the laws (or any regulations thereunder) of the United States or any
political subdivision or taxing authority thereof or therein, or as a result of
any official or administrative pronouncement or action or judicial decision
interpreting or applying such laws or regulations, which amendment or change is
effective or which pronouncement or decision is announced on or after the date
of issuance of the Trust C Capital Securities, there is more than an
insubstantial risk that (i) the Trust C Issuer is, or will be within 90 days of
the delivery of such opinion, subject to United States federal income tax with
respect to income received or accrued on the Trust C Subordinated Debentures,
(ii) interest payable by the Corporation on the Trust C Subordinated Debentures
is not, or within 90 days of the delivery of such opinion will not be,
deductible by the Corporation, in whole or in part, for United States federal
income tax purposes or (iii) the Trust C Issuer is, or will be within
                                       S-7
<PAGE>   8
 
90 days of the delivery of the opinion, subject to more than a de minimis amount
of other taxes, duties or other governmental charges. See "Certain Federal
Income Tax Consequences--Pending Tax Litigation Affecting the Trust C Capital
Securities" for a discussion of pending United States Tax Court litigation that,
if decided adversely to the taxpayer, could give rise to a Tax Event, which may
permit the Corporation to redeem the Trust C Subordinated Debentures prior to
June 1, 2008.
 
     An "Investment Company Event" means the receipt by the Trust C Issuer of an
opinion of counsel to the Corporation experienced in such matters to the effect
that, as a result of the occurrence of a change of law or regulation or a
written change (including any announced prospective change) in interpretation or
application of law or regulation by any legislative body, court, governmental
agency or regulatory authority, there is more than an insubstantial risk that
the Trust C Issuer is or will be considered an "investment company" that is
required to be registered under the Investment Company Act of 1940, as amended
(the "Investment Company Act"), which change or prospective change becomes
effective or would become effective, as the case may be, on or after the date of
the issuance of the Trust C Capital Securities.
 
     A "Capital Treatment Event" means the reasonable determination by the
Corporation that, as a result of the occurrence of any amendment to, or change
(including any announced prospective change) in, the laws (or any rules or
regulations thereunder) of the United States or any political subdivision
thereof or therein, or as a result of any official or administrative
pronouncement or action or judicial decision interpreting or applying such laws
or regulations, which amendment or change is effective or such pronouncement,
action or decision is announced on or after the date of issuance of the Trust C
Capital Securities, there is more than an insubstantial risk that the
Corporation will not be entitled to treat an amount equal to the Liquidation
Amount of the Trust C Capital Securities as "Tier 1 Capital" (or the then
equivalent thereof) for purposes of the risk-based capital adequacy guidelines
of the Federal Reserve, as then in effect and applicable to the Corporation.
 
EXCHANGE OF TRUST C CAPITAL SECURITIES FOR TRUST C SUBORDINATED DEBENTURES
 
     The holders of all the outstanding Common Securities have the right at any
time to dissolve the Trust C Issuer and, after satisfaction of liabilities to
creditors of the Trust C Issuer as provided by applicable law, cause the Trust C
Subordinated Debentures to be distributed to the holders of the Trust C Capital
Securities and Trust C Common Securities in liquidation of the Trust C Issuer.
The ability of the Corporation to dissolve the Trust C Issuer may be subject to
prior regulatory approval of the Federal Reserve, if then required under
applicable Federal Reserve capital guidelines or policies. See "Certain Terms of
Trust C Capital Securities--Liquidation of Trust C Issuer and Distribution of
Trust C Subordinated Debentures to Holders" and "Description of Capital
Securities--Redemption or Exchange" in the accompanying Prospectus.
 
     Under current United States federal income tax law and interpretations and
assuming, as expected, that the Trust C Issuer will not be taxable as a
corporation, a distribution of the Trust C Subordinated Debentures upon a
liquidation of the Trust C Issuer will not be a taxable event to holders of the
Trust C Capital Securities. However, if a Tax Event were to occur that would
cause the Trust C Issuer to be subject to United States federal income tax with
respect to income received or accrued on the Trust C Subordinated Debentures, a
distribution of the Trust C Subordinated Debentures by the Trust C Issuer would
be a taxable event to the Trust C Issuer and the holders of the Trust C Capital
Securities. See "Certain Federal Income Tax Consequences--US Holders--Receipt of
Trust C Subordinated Debentures or Cash Upon Liquidation of the Trust C Issuer."
 
RIGHTS UNDER THE TRUST C GUARANTEE
 
     Bankers Trust Company will act as the trustee under the Trust C Guarantee
(the "Guarantee Trustee") and will hold the Trust C Guarantee for the benefit of
the holders of the Trust C Capital Securities. Bankers Trust Company will also
act as Debenture Trustee for the Trust C Subordinated Debentures and as Property
Trustee under the Trust C Trust Agreement. Bankers Trust (Delaware) will act as
Delaware Trustee under the Trust C Trust Agreement. The Trust C Guarantee
guarantees to the holders of the Trust C Capital Securities the following
payments, to the extent not paid by or on behalf of the Trust C Issuer: (i) any
accumulated and unpaid Distributions required to be paid on the Trust C Capital
Securities, to the extent that the Trust C Issuer has funds on hand available
therefor at such time, (ii) the Redemption Price (as defined herein) with
respect to any Trust C Capital Securities called for redemption, to the extent
that the Trust C Issuer has funds on hand available therefor at such time, and
(iii) upon a voluntary or involuntary termination, winding up or liquidation of
the Trust C Issuer
                                       S-8
<PAGE>   9
 
(unless the Trust C Subordinated Debentures are distributed to holders of the
Trust C Capital Securities), the lesser of (a) the aggregate of the Liquidation
Amount and all accumulated and unpaid Distributions to the date of payment, to
the extent that the Trust C Issuer has funds on hand available therefor at such
time, and (b) the amount of assets of the Trust C Issuer remaining available for
distribution to holders of the Trust C Capital Securities in liquidation of the
Trust C Issuer. The Trust C Guarantee is subordinated as described under
"--Ranking of Subordinated Obligations Under the Trust C Guarantee and the Trust
C Subordinated Debentures" and under "Description of Guarantee--Status of the
Guarantee" in the accompanying Prospectus. The holders of not less than a
majority in aggregate of Liquidation Amount of the outstanding Trust C Capital
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Guarantee Trustee in respect of the
Trust C Guarantee or to direct the exercise of any trust power conferred upon
the Guarantee Trustee under the Trust C Guarantee. Any holder of the Trust C
Capital Securities may institute a legal proceeding directly against the
Corporation to enforce its rights under the Trust C Guarantee without first
instituting a legal proceeding against the Trust C Issuer, the Guarantee Trustee
or any other person or entity.
 
     If the Corporation were to default on its obligations to pay amounts
payable under the Trust C Subordinated Debentures, the Trust C Issuer may lack
funds for the payment of Distributions or amounts payable on redemption of the
Trust C Capital Securities or otherwise, and, in such event, holders of the
Trust C Capital Securities would not be able to rely upon the Trust C Guarantee
for payment of such amounts. Instead, if a Debenture Event of Default has
occurred and is continuing and such event is attributable to the failure of the
Corporation to pay any amounts payable in respect of the Trust C Subordinated
Debentures on the payment date on which such payment is due and payable, then a
holder of the Trust C Capital Securities may institute a legal proceeding
directly against the Corporation for enforcement of payment to such holder of
any amounts payable in respect to such Trust C Subordinated Debentures having a
principal amount equal to the aggregate Liquidation Amount of the Trust C
Capital Securities of such holder (a "Direct Action"). In connection with such
Direct Action, the Corporation will have a right of set-off under the Indenture
to the extent of any payment made by the Corporation to such holder of Trust C
Capital Securities in the Direct Action. Except as described herein, holders of
Trust C Capital Securities will not be able to exercise directly any other
remedy available to the holders of the Trust C Subordinated Debentures or assert
directly any other right in respect of the Trust C Subordinated Debentures. See
"Description of Junior Subordinated Debentures--Enforcement of Certain Rights by
Holders of Capital Securities," "--Debenture Events of Default" and "Description
of Guarantees" in the accompanying Prospectus. The Trust C Trust Agreement
provides that each holder of Trust C Capital Securities by acceptance thereof
agrees to the provisions of the Trust C Guarantee and the Indenture.
 
LIMITED VOTING RIGHTS
 
     Holders of Trust C Capital Securities will have limited voting rights
relating generally to the modification of the Trust C Capital Securities and the
Trust C Guarantee and the exercise of the Trust C Issuer's rights as holder of
Trust C Subordinated Debentures. Holders of Trust C Capital Securities will not
be entitled to appoint, remove or replace the Property Trustee or the Delaware
Trustee except upon the occurrence of certain events specified in the Trust C
Trust Agreement and described herein. The Property Trustee and the holders of
all the Trust C Common Securities may, subject to certain conditions, amend the
Trust C Trust Agreement without the consent of holders of Trust C Capital
Securities to cure any ambiguity or make other provisions not inconsistent with
the Trust C Trust Agreement or to ensure that the Trust C Issuer (i) will not be
taxable as a corporation for United States federal income tax purposes, or (ii)
will not be required to register as an "investment company" under the Investment
Company Act. See "Description of Capital Securities--Voting Rights; Amendment of
Trust Agreement" and "--Removal of Issuer Trustees; Appointment of Successors"
in the accompanying Prospectus.
 
MARKET PRICES
 
     There can be no assurance as to the market prices for Trust C Capital
Securities, or the market prices for Trust C Subordinated Debentures that may be
distributed in exchange for Trust C Capital Securities if a liquidation of the
Trust C Issuer occurs. Accordingly, the Trust C Capital Securities that an
investor may purchase, whether pursuant to the offer made hereby or in the
secondary market, or the Trust C Subordinated
 
                                       S-9
<PAGE>   10
 
Debentures that a holder of Trust C Capital Securities may receive on
liquidation of the Trust C Issuer, may trade at a discount to the price that the
investor paid to purchase the Trust C Capital Securities offered hereby. Because
holders of Trust C Capital Securities may receive Trust C Subordinated
Debentures on termination of the Trust C Issuer, prospective purchasers of Trust
C Capital Securities are also making an investment decision with regard to the
Trust C Subordinated Debentures and should carefully review all the information
regarding the Trust C Subordinated Debentures contained herein. See "Certain
Terms of Trust C Subordinated Debentures" and "Description of Junior
Subordinated Debentures--Corresponding Junior Subordinated Debentures" in the
accompanying Prospectus.
 
ABSENCE OF PRIOR PUBLIC MARKET
 
     Prior to this offering, there has been no public market for the Trust C
Capital Securities. There can be no assurance that an active trading market will
develop for the Trust C Capital Securities or that, if such market develops, the
market price will equal or exceed the public offering price set forth on the
cover page of this Prospectus Supplement. The public offering price for the
Trust C Capital Securities has been determined through negotiations between the
Corporation and the Underwriters (as defined herein). Prices for the Trust C
Capital Securities will be determined in the marketplace and may be influenced
by many factors, including the liquidity of the market for the Trust C Capital
Securities, investor perceptions of the Corporation and general industry and
economic conditions.
 
TRADING CHARACTERISTICS OF TRUST C CAPITAL SECURITIES
 
     The Corporation does not intend to have the Trust C Capital Securities
listed on the New York Stock Exchange or any other securities exchange.
 
     The Trust C Capital Securities may trade at prices that do not fully
reflect the value of accrued and unpaid interest with respect to the underlying
Trust C Subordinated Debentures. See "Certain Federal Income Tax
Consequences--US Holders--Interest Income and Original Issue Discount" and
"--Sales or Redemption of Trust C Capital Securities" for a discussion of the
United States federal income tax consequences that may result from a taxable
disposition of the Trust C Capital Securities.

     While the Corporation manages seven lines of business, the corporate legal
structure consists of 4 subsidiary banks and 109 nonbank subsidiaries. PNC Bank,

                CONSOLIDATED RATIO OF EARNINGS TO FIXED CHARGES
 
     The following unaudited table presents the consolidated ratio of earnings
to fixed charges of the Corporation. 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 expenses (other than on deposits) includes interest on bank notes and
senior debt, federal funds purchased, repurchase agreements, other borrowed
funds and subordinated debt.

                              PNC CAPITAL TRUST C
 
     The Trust C Issuer is a statutory business trust formed under Delaware law
pursuant to (i) a trust agreement executed by the Corporation, as Depositor of
the Trust C Issuer, and the Delaware Trustee and (ii) the filing of a
Certificate of Trust with the Delaware Secretary of State on April 16, 1998. The
Trust C Issuer will be governed by the Trust C Trust Agreement. Two individuals
will be selected by the holders of the Trust C Common Securities to act as
administrators with respect to the Trust C Issuer (the "Administrators"). The
Corporation, while holder of the Trust C Common Securities, intends to select
two individuals who are employees or officers of or affiliated with the
Corporation to serve as the Administrators. The Trust C Issuer exists for the
exclusive purposes of (i) issuing and selling the Trust C Trust Securities, (ii)
investing the gross proceeds of such Trust C Trust Securities in the Trust C
Subordinated Debentures and (iii) engaging in only those other activities
necessary, convenient or incidental thereto. Accordingly, the Trust C
Subordinated Debentures will be the sole assets of the Trust C Issuer and
payments under the Trust C Subordinated Debentures owned by the Trust C Issuer
will be the sole revenue of the Trust C Issuer.
 
     All of the Trust C Common Securities will initially be owned directly or
indirectly by the Corporation. The Trust C Common Securities will rank pari
passu, and payments will be made thereon pro rata, with the Trust C Capital
Securities, except that upon the occurrence and continuation of a Debenture
Event of Default arising as a result of any failure by the Corporation to pay
any amounts in respect of the Trust C Subordinated Debentures owned by the Trust
C Issuer when due, the rights of the Corporation as the holder of the Trust C
Common Securities to payment in respect of Distributions and payments upon
liquidation, redemption or otherwise will be subordinated to the rights of the
holders of the Trust C Capital Securities. See "Description of Capital
Securities--Subordination of Common Securities" in the accompanying Prospectus.
The Corporation will acquire Trust C Common Securities in an aggregate
Liquidation Amount equal to at least 3% of the total capital of the Trust C
Issuer.
 
     The Trust C Issuer has a term of 55 years, but may dissolve earlier as
provided in the Trust C Trust Agreement. The name and address of the Delaware
Trustee for the Trust C Issuer is Bankers Trust (Delaware), 1011 Centre Road,
Suite 200, Wilmington, Delaware 19805, telephone number (302) 636-3305, and the
name and address of the Property Trustee, the Guarantee Trustee and the
Debenture Trustee is Bankers Trust Company, Four Albany Street, 4th Floor, New
York, New York 10006, telephone number (212) 250-2500.
 
                                USE OF PROCEEDS
 
     The Trust C Issuer will use all proceeds received from the sale of the
Trust C Securities to purchase Trust C Subordinated Debentures from the
Corporation. The Corporation intends to use the proceeds from the sale of the
Trust C Subordinated Debentures for general corporate purposes, which may
include the repayment of indebtedness, repurchases of outstanding common stock
of the Corporation, investments in or extensions of credit to its subsidiaries
and/or the financing of possible acquisitions. Pending such use, the net
proceeds may be temporarily invested. The precise amounts and timing of the
application of proceeds will depend upon the funding requirements of the
Corporation and its subsidiaries and the availability of other funds. In view of
anticipated funding requirements, the Corporation may from time to time engage
in additional financing of a character and in amounts to be determined.
 
                  CERTAIN TERMS OF TRUST C CAPITAL SECURITIES
 
GENERAL
 
     The following summary of certain terms and provisions of the Trust C
Capital Securities supplements the description of the terms and provisions of
the Capital Securities set forth in the accompanying Prospectus under the
heading "Description of Capital Securities," to which description reference is
hereby made. This summary of certain terms and provisions of the Trust C Capital
Securities, which describes the material provisions thereof, does not purport to
be complete and is subject to, and qualified in its entirety by reference to,
the Trust C Trust Agreement to which reference is hereby made. The form of the
Trust C Trust Agreement has been filed as an
 
                                      S-12
<PAGE>   13
 
exhibit to the Registration Statement of which this Prospectus Supplement and
the accompanying Prospectus form a part.
 
DISTRIBUTIONS
 
     The Trust C Capital Securities represent preferred undivided beneficial
ownership interests in the Trust C Issuer, and Distributions on the Trust C
Capital Securities will be payable at the Distribution Rate on the stated
Liquidation Amount of $1,000, payable quarterly in arrears on March 1, June 1,
September 1 and December 1 of each year (each a "Distribution Date"), to the
holders of the Trust C Capital Securities on the relevant record dates. The
record dates for the Trust C Capital Securities will be the 15th day of the
month immediately prior to the month in which the relevant Distribution Date
occurs. Distributions will accumulate from the date of original issuance. The
first Distribution Date for the Trust C Capital Securities will be September 1,
1998. The amount of Distributions payable for any period less than a full
Distribution period will be computed on the basis of a 360-day year of twelve
30-day months and the actual days elapsed in a partial month in such period. In
the event that any Distribution Date would otherwise fall on a day that is not a
Business Day, such Distribution Date shall be postponed to the next day that is
a Business Day (without any additional Distributions or other payment in respect
of such delay). See "Description of Capital Securities--Distributions" in the
accompanying Prospectus. The period beginning on, and including, the date of
original issuance of the Trust C Capital Securities, and ending on, but
excluding, the first Distribution Date, and each successive period beginning on,
and including, a Distribution Date, and ending on, but excluding, the next
succeeding Distribution Date is herein called a "Distribution Period."
 
  Determination of 3-Month LIBOR
 
     The Distribution Rate in respect of the Trust C Capital Securities will be
a variable rate per annum determined by reference to "3-Month LIBOR" determined
as described below, plus a spread of 0.57%, "3-Month LIBOR" means the London
interbank offered rate for three-month, U.S. dollar deposits and, with respect
to any Distribution Period, will be calculated by Bankers Trust Company, as
calculation agent (the "Calculation Agent"), as follows:
 
          (a) On the second Market Day (as defined below) preceding the
     commencement of such Distribution Period (each, a "Determination Date"),
     3-Month LIBOR will be determined on the basis of the offered rate for
     deposits of not less than U.S. $1,000,000 for a period of three months (the
     "Index Maturity"), commencing on said Determination Date, which appears on
     the display designation as page 3750 on the Dow Jones Telerate Service (or
     such other pages as may replace page 3750 on that service for the purpose
     of displaying London interbank offered rates of major banks) ("Telerate
     Page 3750") as of 11:00 a.m., London time, on said Determination Date. If
     no such offered rate appears, 3-Month LIBOR with respect to such
     Distribution Period will be determined as described in (b) below.
 
          (b) With respect to a Determination Date on which no such offered rate
     appears on Telerate Page 3750 as described in (a) above, 3-Month LIBOR
     shall be the arithmetic mean, expressed as a percentage, of the offered
     rates (unless by its terms such display provides for only a single rate, in
     which case a single rate shall be used) for deposits in U.S. dollars for
     the Index Maturity that appears on the display designated as "LIBO" on the
     Reuters Monitor Money Market Rates Service (or such other page as may
     replace the LIBO page on that service for the purpose of displaying London
     interbank offered rates of major banks) ("Reuters Screen LIBO Page") as of
     11:00 a.m., London time, on such date. If, in turn, at least two such rates
     are not displayed on the Reuters Screen LIBO Page at such time (unless, as
     aforesaid, only a single rate is required), the Calculation Agent will
     obtain from each of four reference banks in London selected by the
     Calculation Agent ("Reference Banks") such bank's offered quotation
     (expressed as a percentage per annum) as of approximately 11:00 a.m.,
     London time, on such date for deposits in U.S. dollars to prime banks in
     the London interbank market for the Index Maturity. If two or more such
     quotations are provided as requested, then 3-Month LIBOR for such date
     shall be the arithmetic average of such quotations. If, in turn, fewer than
     two such quotations are provided as requested, then 3-Month LIBOR for such
     date will be obtained from the preceding Market Day for which the Telerate
     Page 3750 displayed a rate for the Index Maturity.
 
                                      S-13
<PAGE>   14
 
          (c) If on any Determination Date, the Calculation Agent is required
     but unable to determine 3-Month LIBOR in the manner provided in paragraphs
     (a) and (b) above, 3-Month LIBOR for such Distribution Period shall be
     3-Month LIBOR as determined on the previous Determination Date.
 
     The term "Market Day" means any Business Day on which commercial banks and
foreign exchange markets are open for business (including dealings in foreign
exchange and foreign currency deposits) in New York and London.
 
     The Distribution Rate for any Distribution Period will at no time be higher
than the maximum rate then permitted by New York law as the same may be modified
by United States law.
 
     All percentages resulting from any calculations referred to in this
Prospectus Supplement will be rounded, if necessary, to the nearest one
ten-thousandth of a percentage point, with five hundred-thousandths of a
percentage point being rounded upwards (e.g., 6.87655% (or .0687655) would be
rounded to 6.8766% (or .068766)), and all U.S. dollar amounts used in or
resulting from such calculations will be rounded to the nearest cent (with
one-half cent or more being rounded upwards).
 
  Determination of Distribution Rate and Calculation of Distribution Amount
 
     The Calculation Agent shall, as soon as practicable after 11:00 a.m.,
London time, on each Determination Date, determine the Distribution Rate and
inform the Debenture Trustee, the Property Trustee and the Paying Agent. Unless
otherwise provided by the Property Trustee, the Paying Agent will calculate the
amount of Distributions payable in respect of the following Distribution Period
(the "Distribution Amount"). The Distribution Amount shall be calculated by
applying the Distribution Rate to the Liquidation Amount of each Trust C Capital
Security outstanding at the commencement of the Distribution Period, multiplying
each such Liquidation Amount by the actual number of days in the Distribution
Period concerned (which actual number of days shall include the first day but
exclude the last day of such Distribution Period) divided by 360 and rounding
the resulting figure to the nearest cent (with one-half cent or more being
rounded upwards). The determination of the Distribution Rate by the Calculation
Agent and the Distribution Amount by the Paying Agent will (in the absence of
willful default, bad faith or manifest error) be final, conclusive and binding
on all concerned. None of the Debenture Trustee, the Property Trustee, the
Paying Agent, the Calculation Agent, the Trust C Issuer or the Corporation (or
any of their respective officers, directors, agents, beneficiaries, employees or
affiliates) shall have any liability to any person for (i) the selection of any
Reference Bank or (ii) any inability to retain major banks in the London
interbank market, in the case of the Calculation Agent, which is caused by
circumstances beyond its reasonable control.
 
     Upon the request of a holder of a Trust C Capital Security, the Calculation
Agent will provide the Distribution Rate then in effect and, if determined, the
Distribution Rate for the next Distribution Period with respect to the Trust C
Capital Securities. Each such Distribution Rate may be obtained by telephoning
the Calculation Agent.
 
  Certificates to be Final
 
     All certificates, communications, opinions, determinations, calculations,
quotations and decisions given, expressed, made or obtained for the purposes of
the provisions relating to the payment and calculation of Distributions on the
Trust C Capital Securities, whether by the Reference Banks (or any of them) or
the Calculation Agent, Property Trustee, Debenture Trustee or Paying Agent, will
(in absence of willful default, bad faith or manifest error) be binding on the
Trust C Issuer, the Corporation, the Issuer Trustees and all of the holders of
the Trust C Capital Securities, and no liability will (in the absence of willful
default, bad faith or manifest error) attach to the Calculation Agent, Property
Trustee, Debenture Trustee or Paying Agent in connection with the exercise or
non-exercise by any of them of their powers, duties and discretion.
 
  Deferral of Distributions
 
     So long as no Debenture Event of Default has occurred and is continuing,
the Corporation has the right under the Indenture to defer payment of interest
on the Trust C Subordinated Debentures at any time or from time
 
                                      S-14
<PAGE>   15
 
to time, for a period not exceeding 20 consecutive quarterly periods with
respect to each Extension Period, provided that no Extension Period may extend
beyond the Stated Maturity of the Trust C Subordinated Debentures. As a
consequence of any such deferral of interest payments by the Corporation,
quarterly Distributions on the Trust C Capital Securities by the Trust C Issuer
will also be deferred during any such Extension Period. Distributions to which
holders of the Trust C Capital Securities are entitled will accumulate
additional Distributions thereon at the Distribution Rate, compounded quarterly
from the relevant payment date for such Distributions, computed on the basis of
a 360-day year of twelve 30-day months and the actual days elapsed in a partial
month in such period. The term "Distributions" as used herein shall include any
such additional Distributions. During any such Extension Period, the Corporation
may not (i) declare or pay any dividends or distributions on, or redeem,
purchase, acquire or make a liquidation payment with respect to, any of the
Corporation's capital stock, or (ii) make any payment of principal of or
interest or premium, if any, on or repay, repurchase or redeem any debt
securities of the Corporation (including other series of Junior Subordinated
Debentures) that rank pari passu in all respects with or junior in interest to
the Trust C Subordinated Debentures (including the 8.315% Subordinated
Debentures) (other than (a) repurchases, redemptions or other acquisitions of
shares of capital stock of the Corporation in connection with any employment
contract, benefit plan or other similar arrangement with or for the benefit of
any one or more employees, officers, directors or consultants, in connection
with a dividend reinvestment or stockholder stock purchase plan or in connection
with the issuance of capital stock of the Corporation (or securities convertible
into or exercisable for such capital stock) as consideration in an acquisition
transaction entered into prior to the applicable Extension Period, (b) as a
result of an exchange or conversion of any class or series of the Corporation's
capital stock (or any capital stock of a subsidiary of the Corporation) for any
class or series of the Corporation's capital stock, or of any class or series of
the Corporation's indebtedness for any class or series of the Corporation's
capital stock, (c) the purchase of fractional interests in shares of the
Corporation's capital stock pursuant to the conversion or exchange provisions of
such capital stock or the security being converted or exchanged, (d) any
declaration of a dividend in connection with any stockholder's rights plan, or
the issuance of rights, stock or other property under any stockholder's rights
plan, or the redemption or repurchase of rights pursuant thereto, or (e) any
dividend in the form of stock, warrants, options or other rights where the
dividend stock or the stock issuable upon exercise of such warrants, options or
other rights is the same stock as that on which the dividend is being paid or
ranks pari passu with or junior to such stock). Prior to the termination of any
such Extension Period, the Corporation may further defer the payment of interest
on the Trust C Subordinated Debentures, provided that no Extension Period may
exceed 20 consecutive quarterly periods or extend beyond the Stated Maturity of
the Trust C Subordinated Debentures. Upon the termination of any such Extension
Period and the payment of all interest then accrued and unpaid (together with
interest thereon at the Interest Rate compounded quarterly, to the extent
permitted by applicable law), the Corporation may elect to begin a new Extension
Period, subject to the above conditions. No interest shall be due and payable
during an Extension Period, except at the end thereof. The Corporation must give
the holders of the Trust C Subordinated Debentures and the Debenture Trustee
notice of its election of such Extension Period at least one Business Day prior
to the earlier of (i) the next succeeding date on which Distributions on the
Trust C Capital Securities would have been payable but for the election to begin
such Extension Period and (ii) the date on which the Property Trustee is
required to give notice to holders of the Trust C Capital Securities of the
record date or the date such Distributions are payable, but in any event not
less than one Business Day prior to such record date. The Property Trustee will
give notice of the Corporation's election to begin a new Extension Period to the
holders of the Trust C Capital Securities. Subject to the foregoing, there is no
limitation on the number of times that the Corporation may elect to begin an
Extension Period. See "Certain Terms of Trust C Subordinated Debentures--Option
to Defer Interest Payments" and "Certain Federal Income Tax Consequences--US
Holders--Interest Income and Original Issue Discount."
 
     The Corporation has no current intention of exercising its right to defer
payments of interest by extending the interest payment period on the Trust C
Subordinated Debentures.
 
     The revenue of the Trust C Issuer available for distribution to holders of
the Trust C Capital Securities will be limited to payments under the Trust C
Subordinated Debentures in which the Trust C Issuer will invest the proceeds
from the issuance and sale of the Trust C Capital Securities. See "Description
of Junior Subordinated Debentures" in the accompanying Prospectus and "Certain
Terms of Trust C Subordinated Debentures" below. If the Corporation does not
make payments on the Trust C Subordinated Debentures, the Trust C Issuer may not
                                      S-15
<PAGE>   16
 
have funds available to pay Distributions or other amounts payable on the Trust
C Capital Securities. The payment of Distributions and other amounts payable on
the Trust C Capital Securities (if and to the extent the Trust C Issuer has
funds legally available for and cash sufficient to make such payments) is
guaranteed by the Corporation on a limited basis as set forth under "Description
of Guarantees" in the accompanying Prospectus and "Certain Terms of Trust C
Guarantee" below.
 
REDEMPTION
 
     Upon the repayment or redemption, in whole or in part, of the Trust C
Subordinated Debentures, whether at Stated Maturity or upon earlier redemption
as provided in the Indenture, the proceeds from such repayment or redemption
shall be applied by the Property Trustee to redeem a Like Amount (as defined in
the accompanying Prospectus) of the Trust C Securities, upon not less than 30
nor more than 60 days' notice prior to the date fixed for redemption, at a
redemption price, with respect to the Trust C Securities (the "Redemption
Price"), equal to the aggregate Liquidation Amount of such Trust C Securities,
plus accumulated and unpaid Distributions thereon to the date of redemption (the
"Redemption Date"). See "Certain Terms of Trust C Subordinated
Debentures--Redemption." If less than all of the Trust C Subordinated Debentures
are to be repaid or redeemed on a Redemption Date, then the proceeds from such
repayment or redemption shall be allocated to the redemption pro rata of the
Trust C Capital Securities and the Trust C Common Securities.
 
     The Corporation has the right to redeem the Trust C Subordinated Debentures
(i) on or after June 1, 2008, in whole at any time or in part from time to time,
in each case, on an Interest Payment Date, or (ii) in whole, but not in part, at
any time within 90 days following the occurrence and during the continuation of
a Tax Event, Investment Company Event or Capital Treatment Event, in each case
subject to receipt of prior approval by the Federal Reserve if then required
under applicable capital guidelines or policies. A redemption of the Trust C
Subordinated Debentures would cause a mandatory redemption of a Like Amount of
the Trust C Securities at the Redemption Price.
 
LIQUIDATION OF TRUST C ISSUER AND DISTRIBUTION OF TRUST C SUBORDINATED
DEBENTURES TO HOLDERS
 
     The Corporation, as holder of all the outstanding Trust C Common
Securities, will have the right at any time to dissolve the Trust C Issuer and,
after satisfaction of liabilities to creditors of the Trust C Issuer as required
by applicable law, to cause the Trust C Subordinated Debentures to be
distributed to the holders of the Trust C Capital Securities in exchange
therefor upon liquidation of the Trust C Issuer. Such right is subject to the
Corporation's having received prior approval of the Federal Reserve if then
required under applicable capital guidelines or policies.
 
     Under current United States federal income tax law and interpretations and
assuming, as expected, the Trust C Issuer is treated as a grantor trust, a
distribution of Trust C Subordinated Debentures in exchange for the Trust C
Capital Securities should not be a taxable event to holders of the Trust C
Capital Securities. Should there be a change in law, a change in legal
interpretation, a Tax Event or other circumstances, however, the distribution
could be a taxable event to holders of the Trust C Capital Securities. See
"Certain Federal Income Tax Consequences--Distribution of Trust C Subordinated
Debentures to Holders of Trust C Capital Securities." If the Corporation elects
neither to redeem the Trust C Subordinated Debentures prior to maturity nor to
liquidate the Trust C Issuer and distribute the Trust C Subordinated Debentures
to holders of the Trust C Capital Securities in exchange therefor, the Trust C
Capital Securities will remain outstanding until the Stated Maturity of the
Trust C Subordinated Debentures.
 
     If the Corporation elects to liquidate the Trust C Issuer and thereby
causes the Trust C Subordinated Debentures to be distributed to holders of the
Trust C Capital Securities in exchange therefor upon liquidation of the Trust C
Issuer, the Corporation shall continue to have the right to redeem the Trust C
Subordinated Debentures in certain circumstances upon the occurrence of a Tax
Event, Investment Company Event or Capital Treatment Event, as described under
"Certain Terms of Trust C Subordinated Debentures--Conditional Right to Redeem
upon a Tax Event, Investment Company Event or Capital Treatment Event."
 
                                      S-16
<PAGE>   17
 
LIQUIDATION VALUE
 
     The amount payable on the Trust C Capital Securities in the event of any
liquidation of the Trust C Issuer is $1,000 per Trust C Capital Security plus
accumulated and unpaid Distributions, which amount may be paid in the form of a
distribution of a Like Amount of Trust C Subordinated Debentures, subject to
certain exceptions. See "Description of Capital Securities--Liquidation Upon
Dissolution" in the accompanying Prospectus.
 
REGISTRATION OF TRUST C CAPITAL SECURITIES
 
     The Trust C Capital Securities will be represented by one or more global
certificates registered in the name of DTC or its nominee. Beneficial interests
in the Trust C Capital Securities will be shown on, and transfers thereof will
be effected only through, records maintained by participants in DTC. Except as
described below and in the accompanying Prospectus, Trust C Capital Securities
in certificated form will not be issued in exchange for the global certificates.
See "Book-Entry Issuance" in the accompanying Prospectus.
 
     A global security shall be exchangeable for Trust C Capital Securities
registered in the names of persons other than DTC or its nominee only if (i) DTC
advises the Corporation and the Issuer Trustees in writing that it is unwilling
or unable to properly discharge its responsibilities as a depositary for such
global security and the Corporation is unable to locate a qualified successor
within 90 days of receipt of such notice from DTC, (ii) the Corporation at its
option advises DTC in writing that it elects to terminate the book-entry system
through DTC or (iii) there shall have occurred and be continuing a Debenture
Event of Default with respect to the Trust C Subordinated Debentures. Any global
security that is exchangeable pursuant to the preceding sentence shall be
exchangeable for definitive certificates registered in such names as DTC shall
direct. It is expected that such instructions will be based upon directions
received by DTC from its Participants (as defined in the accompanying
Prospectus) with respect to ownership of beneficial interests in such global
security. In the event that Trust C Capital Securities are issued in definitive
form, such Trust C Capital Securities will be in denominations of $1,000 and
integral multiples thereof and may be transferred or exchanged at the offices
described below.
 
     Payments on, and any distributions of Trust C Subordinated Debentures in
exchange for, Trust C Capital Securities represented by a global security will
be made to DTC, as the depositary for the Trust C Capital Securities. In the
event Trust C Capital Securities are not held by DTC, (a) the Liquidation Amount
and Distributions will be payable by check mailed to the address of the persons
entitled thereto as such appears on the securities register for the Trust C
Capital Securities and (b) (i) the transfer of the Trust C Capital Securities
will be registrable, (ii) Trust C Subordinated Debentures will be distributed in
exchange for Trust C Capital Securities following a termination of the Trust C
Issuer, and (iii) Trust C Capital Securities will be exchangeable for Trust C
Capital Securities of other denominations of a like aggregate Liquidation
Amount, at the corporate office of the Property Trustee in New York, New York,
or at the offices of any paying agent or transfer agent appointed by the
Administrators or the Property Trustee. For a description of DTC and the terms
of the depositary arrangements relating to payments, transfers, voting rights,
redemptions and other notices and other matters, see "Book-Entry Issuance" in
the accompanying Prospectus.
 
                CERTAIN TERMS OF TRUST C SUBORDINATED DEBENTURES
 
GENERAL
 
     The Trust C Subordinated Debentures will be issued as a series of junior
subordinated deferrable interest debentures under the Indenture. The following
summary of certain terms and provisions of the Trust C Subordinated Debentures
supplements the description of the terms and provisions of the Corresponding
Junior Subordinated Debentures (as defined in the accompanying Prospectus) set
forth in the accompanying Prospectus under the heading "Description of Junior
Subordinated Debentures" to which description reference is hereby made. The
summary of certain terms and provisions of the Trust C Subordinated Debentures
set forth below, which describes the material provisions thereof, does not
purport to be complete and is subject to, and qualified in its entirety by
reference to, the Indenture, to which reference is hereby made. The form of the
Indenture has been filed as an exhibit to the Registration Statement of which
this Prospectus Supplement and the accompanying Prospectus form a part.
 
                                      S-17
<PAGE>   18
 
     Concurrently with the issuance of the Trust C Capital Securities, the Trust
C Issuer will invest the proceeds thereof, together with the consideration paid
by the Corporation for the Trust C Common Securities, in the Trust C
Subordinated Debentures issued by the Corporation. The Trust C Subordinated
Debentures will bear interest at a floating rate per annum equal to 3-Month
LIBOR (determined in the same manner as the Distribution Rate, as described
under "Certain Terms of Trust C Capital Securities--Distributions--Determination
of 3-Month LIBOR") plus a spread of 0.57% (the "Interest Rate"), payable
quarterly in arrears on March 1, June 1, September 1 and December 1 of each year
(each, an "Interest Payment Date"), commencing September 1, 1998, and at
maturity to the person in whose name each Trust C Subordinated Debenture is
registered at the close of business on the 15th day of the month immediately
prior to the month in which the relevant Interest Payment Date occurs. It is
anticipated that, until the liquidation, if any, of the Trust C Issuer, each
Trust C Subordinated Debenture will be registered in the name of the Trust C
Issuer and held by the Property Trustee in trust for the benefit of the holders
of the Trust C Securities. The amount of interest payable for any period less
than a full interest period will be computed on the basis of a 360-day year of
twelve 30-day months and the actual days elapsed in a partial month in such
period. In the event that any Interest Payment Date would otherwise fall on a
day that is not a Business Day, such Interest Payment Date shall be postponed to
the next day that is a Business Day (without any interest or other payment in
respect of any such delay). Accrued interest that is not paid on the applicable
Interest Payment Date will bear additional interest on the amount thereof (to
the extent permitted by law) at the Interest Rate, compounded quarterly and
computed on the basis of a 360-day year of twelve 30-day months and the actual
days elapsed in a partial month in such period. The term "interest" as used
herein shall include quarterly interest payments and interest on quarterly
interest payments not paid on the applicable Interest Payment Date, as
applicable. Notwithstanding anything to the contrary set forth above, if the
maturity date falls on a day that is not a Business Day, the payment of
principal and interest will be paid on the next succeeding Business Day, with
the same force and effect as if made on such maturity date and no interest on
such payments will accrue from and after the maturity date.
 
     The Trust C Subordinated Debentures will mature on June 1, 2028, subject to
the Maturity Adjustment (such date, as it may be shortened by the Maturity
Adjustment is referred to herein as the Stated Maturity). The Maturity
Adjustment represents the right of the Corporation to shorten the maturity date
once at any time to any date not earlier than June 1, 2008 subject to the
Corporation having received prior approval by the Federal Reserve if then
required under applicable capital guidelines or policies. In the event the
Corporation elects to shorten the Stated Maturity of the Trust C Subordinated
Debentures, it will give notice to the registered holders of the Trust C
Subordinated Debentures, the Debenture Trustee and the Trust C Issuer of such
shortening no less than 90 days prior to the effectiveness thereof. The Property
Trustee must give notice to the holders of the Trust C Securities of the
shortening of the Stated Maturity at least 30 but not more than 60 days before
such date.
 
     The Trust C Subordinated Debentures will be unsecured and will rank junior
and be subordinate in right of payment to all Senior Indebtedness of the
Corporation. See "Description of Junior Subordinated Debentures--Subordination"
in the accompanying Prospectus. Because the Corporation is a holding company,
the right of the Corporation to participate in any distribution of assets of any
subsidiary, including PNC Bank, upon such subsidiary's liquidation or
reorganization or otherwise, is subject to the prior claims of creditors of that
subsidiary, except to the extent that the Corporation may itself be recognized
as a creditor of that subsidiary. Accordingly, the Trust C Subordinated
Debentures and the Trust C Guarantee will be effectively subordinated to all
existing and future liabilities of the Corporation's subsidiaries, and holders
of Trust C Subordinated Debentures and beneficiaries of the Trust C Guarantee
should look only to the assets of the Corporation for payments on the Trust C
Subordinated Debentures or under the Trust C Guarantee. The Indenture does not
limit the incurrence or issuance of other secured or unsecured debt of the
Corporation, including Senior Indebtedness, whether under the Indenture, any
other existing indenture or any other indenture that the Corporation may enter
into in the future or otherwise. See "Description of Junior Subordinated
Debentures--Subordination" in the accompanying Prospectus.
 
OPTION TO DEFER INTEREST PAYMENTS
 
     So long as no Debenture Event of Default has occurred and is continuing,
the Corporation has the right under the Indenture at any time or from time to
time during the term of the Trust C Subordinated Debentures to
 
                                      S-18
<PAGE>   19
 
defer the payment of interest on the Trust C Subordinated Debentures for a
period not exceeding 20 consecutive quarterly periods with respect to each
Extension Period, provided that no Extension Period may extend beyond the Stated
Maturity of the Trust C Subordinated Debentures. At the end of such Extension
Period, the Corporation must pay all interest then accrued and unpaid on the
Trust C Subordinated Debentures (together with interest on such unpaid interest
at the Interest Rate, compounded quarterly and computed on the basis of a
360-day year of twelve 30-day months and the actual days elapsed in a partial
month in such period, to the extent permitted by applicable law). During an
Extension Period, interest will continue to accrue and holders of Trust C
Subordinated Debentures (or holders of Trust C Capital Securities while such
series is outstanding) will be required to accrue interest income for United
States federal income tax purposes. See "Certain Federal Income Tax
Consequence--US Holders--Interest Income and Original Issue Discount."
 
     During any such Extension Period, the Corporation may not (i) declare or
pay any dividends or distributions on, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of the Corporation's capital stock, or
(ii) make any payment of principal of or interest or premium, if any, on or
repay, repurchase or redeem any debt securities of the Corporation (including
other series of Junior Subordinated Debentures) that rank pari passu in all
respects with or junior in interest to the Trust C Subordinated Debentures
(other than (a) repurchases, redemptions or other acquisitions of shares of
capital stock of the Corporation in connection with any employment contract,
benefit plan or other similar arrangement with or for the benefit of any one or
more employees, officers, directors or consultants, in connection with a
dividend reinvestment or stockholder stock purchase plan or in connection with
the issuance of capital stock of the Corporation (or securities convertible into
or exercisable for such capital stock) as consideration in an acquisition
transaction entered into prior to the applicable Extension Period, (b) as a
result of an exchange or conversion of any class or series of the Corporation's
capital stock (or any capital stock of a subsidiary of the Corporation) for any
class or series of the Corporation's capital stock or of any class or series of
the Corporation's indebtedness for any class or series of the Corporation's
capital stock, (c) the purchase of fractional interests in shares of the
Corporation's capital stock pursuant to the conversion or exchange provisions of
such capital stock or the security being converted or exchanged, (d) any
declaration of a dividend in connection with any stockholder's rights plan, or
the issuance of rights, stock or other property under any stockholder's rights
plan, or the redemption or repurchase of rights pursuant thereto, or (e) any
dividend in the form of stock, warrants, options or other rights where the
dividend stock or the stock issuable upon exercise of such warrants, options or
other rights is the same stock as that on which the dividend is being paid or
ranks pari passu with or junior to such stock). Prior to the termination of any
such Extension Period, the Corporation may further defer the payment of interest
on the Trust C Subordinated Debentures, provided that no Extension Period may
exceed 20 consecutive quarterly periods or extend beyond the Stated Maturity of
the Trust C Subordinated Debentures. Upon the termination of any such Extension
Period and the payment of all amounts then due, the Corporation may elect to
begin a new Extension Period subject to the above requirements. No interest
shall be due and payable during an Extension Period, except at the end thereof.
The Corporation must give the Issuer Trustees notice of its election to begin
such Extension Period at least one Business Day prior to the earlier of (i) the
date Distributions on the Trust C Securities would have been payable except for
the election to begin such Extension Period and (ii) the date the Property
Trustee is required to give notice to holders of Trust C Capital Securities of
the record date for such Distributions, but in any event not less than one
Business Day prior to such record date. The Property Trustee shall give notice
of the Corporation's election to begin a new Extension Period to the holders of
the Trust C Capital Securities. There is no limitation on the number of times
that the Corporation may elect to begin an Extension Period. See "Description of
Junior Subordinated Debentures--Option to Defer Interest Payments" in the
accompanying Prospectus.
 
TRUST COSTS AND EXPENSES
 
     In the Indenture, the Corporation, as borrower, has agreed to pay all debts
and other obligations (other than with respect to the Trust C Capital
Securities) and all costs and expenses of the Trust C Issuer (including costs
and expenses relating to the organization of the Trust C Issuer, the fees and
expenses of the Issuer Trustees and the costs and expenses relating to the
operation of the Trust C Issuer) and to pay any and all taxes and all costs and
expenses with respect thereto (other than United States withholding taxes) to
which the Trust C Issuer might become subject.

<PAGE>   20
 
REDEMPTION
 
     Subject to the Corporation's having received prior approval by the Federal
Reserve if then required under applicable capital guidelines or policies, the
Trust C Subordinated Debentures are redeemable prior to maturity at the option
of the Corporation (i) on or after June 1, 2008 in whole at any time or in part
from time to time or (ii) in whole, but not in part, at any time, within 90 days
following the occurrence and during the continuation of a Tax Event, Investment
Company Event or Capital Treatment Event. The proceeds of any such redemption
will be used by the Trust C Issuer to redeem the Trust C Securities.
 
     The redemption price with respect to the Trust C Subordinated Debentures
shall be equal to 100% of the principal amount of the Trust C Subordinated
Debentures so redeemed plus accrued and unpaid interest thereon to the date of
redemption.
 
DISTRIBUTION OF TRUST C SUBORDINATED DEBENTURES
 
     As described under "Certain Terms of Trust C Capital
Securities--Liquidation of Trust C Issuer and Distribution of Trust C
Subordinated Debentures to Holders," under certain circumstances involving the
termination of the Trust C Issuer, Trust C Subordinated Debentures may be
distributed to the holders of the Trust C Capital Securities in exchange
therefor upon liquidation of the Trust C Issuer after satisfaction of
liabilities to creditors of the Trust C Issuer as provided by applicable law. If
distributed to holders of Trust C Capital Securities, the Trust C Subordinated
Debentures will initially be issued in the form of one or more global securities
and DTC, or any successor depositary for the Trust C Capital Securities, will
act as depositary for the Trust C Subordinated Debentures. It is anticipated
that the depositary arrangements for the Trust C Subordinated Debentures would
be substantially identical to those in effect for the Trust C Capital
Securities. If Trust C Subordinated Debentures are distributed to the holders of
Trust C Capital Securities in exchange therefor upon the liquidation of the
Trust C Issuer, the Trust C Subordinated Debentures will not be listed on the
New York Stock Exchange or any other stock exchange or automated quotation
system. There can be no assurance as to the market for or price of any Trust C
Subordinated Debentures that may be distributed to the holders of Trust C
Capital Securities.
 
REGISTRATION OF TRUST C SUBORDINATED DEBENTURES
 
     The Trust C Subordinated Debentures will be registered in the name of the
Trust C Issuer. In the event that the Trust C Subordinated Debentures are
distributed to holders of Trust C Capital Securities, it is anticipated that the
depositary and other arrangements for the Trust C Subordinated Debentures will
be substantially identical to those in effect for the Trust C Capital
Securities, as applicable. See "Certain Terms of Trust C Capital
Securities--Registration of Trust C Capital Securities."
 
                        CERTAIN TERMS OF TRUST GUARANTEE
 
     The Trust C Guarantee guarantees to the holders of the Trust C Securities
the following payments, to the extent not paid by the Trust C Issuer: (i) any
accumulated and unpaid Distributions required to be paid on the Trust C Capital
Securities, to the extent that the Trust C Issuer has funds on hand available
therefor at such time, (ii) the Redemption Price with respect to any Trust C
Capital Securities called for redemption, to the extent that the Trust C Issuer
has funds on hand available therefor at such time, and (iii) upon a voluntary or
involuntary termination, winding-up or liquidation of the Trust C Issuer (unless
the Trust C Subordinated Debentures are distributed to holders of the Trust C
Capital Securities), the lesser of (a) the aggregate of the Liquidation Amount
and all accumulated and unpaid Distributions to the date of payment, to the
extent that the Trust C Issuer has funds on hand available therefor at such
time, and (b) the amount of assets of the Trust C Issuer remaining available for
distribution to holders of the Trust C Capital Securities in liquidation of the
Trust C Issuer. The Trust C Guarantee will be qualified as an indenture under
the Trust Indenture Act. Bankers Trust Company will act as the Guarantee Trustee
for the purposes of compliance with the Trust Indenture Act and will hold the
Trust C Guarantee for the benefit of the holders of the Trust C Securities.
Bankers Trust Company will also act as Debenture Trustee for the Trust C
Subordinated Debentures and as Property Trustee for the Trust C Securities.
 
                                      S-20
<PAGE>   21
 
     The holders of not less than a majority in aggregate Liquidation Amount of
the outstanding Trust C Capital Securities have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Guarantee Trustee in respect of the Trust C Guarantee or to direct the exercise
of any trust power conferred upon the Guarantee Trustee under the Trust C
Guarantee. Any holder of the Trust C Capital Securities may institute a legal
proceeding directly against the Corporation to enforce its rights under the
Trust C Guarantee without first instituting a legal proceeding against the Trust
C Issuer, the Guarantee Trustee or any other person or entity. If the
Corporation were to default on its obligation to pay amounts payable under the
Trust C Subordinated Debentures, the Trust C Issuer would lack funds for the
payment of Distributions or amounts payable on redemption of the Trust C
Securities or otherwise, and, in such event, holders of the Trust C Capital
Securities would not be able to rely upon the Trust C Guarantee for payment of
such amounts. Instead, if a Debenture Event of Default shall have occurred and
be continuing and such event is attributable to the failure of the Corporation
to pay interest on or principal of the Trust C Subordinated Debentures on the
applicable payment date, then a holder of Trust C Capital Securities may
institute a Direct Action against the Corporation pursuant to the terms of the
Indenture for enforcement of payment to such holder of the principal of or
interest on such Trust C Subordinated Debentures having a principal amount equal
to the aggregate Liquidation Amount of the Trust C Capital Securities of such
holder. In connection with such Direct Action, the Corporation will have a right
of set-off under the Indenture to the extent of any payment made by the
Corporation to such holder of Trust C Capital Securities in the Direct Action.
Except as described herein, holders of Trust C Capital Securities will not be
able to exercise directly any other remedy available to the holders of the Trust
C Subordinated Debentures or assert directly any other rights in respect of the
Trust C Subordinated Debentures. See "Description of Guarantees" in the
accompanying Prospectus. The Trust C Agreement provides that each holder of
Trust C Securities by acceptance thereof agrees to the provisions of the Trust C
Guarantee and the Indenture.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
GENERAL
 
     In the opinion of Arnold & Porter, in its capacity as special tax counsel
to the Corporation and the Trust C Issuer ("Tax Counsel"), the discussion of
United States federal income taxation which follows summarizes the material
United States federal income tax consequences of the purchase, ownership and
disposition of the Trust C Capital Securities.
 
     The summary is based on the Internal Revenue Code of 1986, as amended (the
"Code"), Treasury regulations thereunder, and administrative and judicial
interpretations thereof, each as of the date hereof, all of which are subject to
change, possibly on a retroactive basis. The authorities on which this summary
is based are subject to various interpretations, and the opinions of Tax Counsel
are not binding on the Internal Revenue Service (the "IRS") or the courts,
either of which could take a contrary position. Moreover, no rulings have been
or will be sought from the IRS with respect to the transactions described
herein. Accordingly, there can be no assurance that the IRS will not challenge
the opinions expressed herein or that a court would not sustain such a
challenge.
 
     Except as otherwise stated, this summary deals only with Trust C Capital
Securities held as a capital asset by a holder who or which (i) purchased the
Trust C Capital Securities upon original issuance at their original offering
price and (ii) is a US Holder (as defined below). The summary does not address
all tax consequences that may be relevant to a US Holder, nor does it address
the tax consequences, except as stated below, to holders that are not US Holders
("Non-US Holders") or to holders that may be subject to special tax treatment
(such as banks, thrift institutions, real estate investment trusts, regulated
investment companies, insurance companies, brokers and dealers in securities or
currencies, certain securities traders, other financial institutions, tax-exempt
organizations, persons holding the Trust C Capital Securities as a position in a
"straddle," as part of a "synthetic security," "hedging," "conversion" or other
integrated investment, persons having a functional currency other than the U.S.
Dollar and certain United States expatriates). Further, this summary does not
address (a) the United States federal income tax consequences to shareholders
in, or partners or beneficiaries of, a holder of the Trust C Capital Securities,
(b) the United States federal alternative minimum tax consequences of the
purchase,
 
                                      S-21
<PAGE>   22
 
ownership or disposition of the Trust C Capital Securities, or (c) any state,
local or foreign tax consequences of the purchase, ownership and disposition of
Trust C Capital Securities.
 
     A "US Holder" means a beneficial owner of the Trust C Capital Securities
who or which is (i) a citizen or individual resident (or is treated as a citizen
or individual resident) of the United States for income tax purposes, (ii) a
corporation or partnership created or organized (or treated as created or
organized for income tax purposes) in or under the laws of the United States or
any political subdivision thereof, (iii) an estate the income of which is
includible in its gross income for United States federal income tax purposes
without regard to its source, or (iv) a trust if (a) a court within the United
States is able to exercise primary supervision over the administration of the
trust and (b) one or more United States persons have the authority to control
all substantial decisions of the trust.
 
     HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE TAX
CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE TRUST C
CAPITAL SECURITIES, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN
AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN UNITED STATES FEDERAL
OR OTHER TAX LAWS. FOR A DISCUSSION OF THE POSSIBLE REDEMPTION OF THE TRUST C
CAPITAL SECURITIES UPON THE OCCURRENCE OF CERTAIN TAX EVENTS, SEE "CERTAIN TERMS
OF TRUST C CAPITAL SECURITIES--REDEMPTION."
 
US HOLDERS
 
  Characterization of the Trust C Issuer
 
     In connection with the issuance of the Trust C Securities, Tax Counsel will
render its opinion generally to the effect that, under then current law and
based on the representations, facts and assumptions set forth in the Prospectus
and in this Prospectus Supplement, and assuming full compliance with the terms
of the Trust C Trust Agreement (and other relevant documents), and based on
certain assumptions and qualifications referenced in the opinion, the Trust C
Issuer will be characterized for United States federal income tax purposes as a
grantor trust and will not be characterized as an association taxable as a
corporation. Accordingly, for United States federal income tax purposes, each
holder of the Trust C Capital Securities generally will be considered the owner
of an undivided interest in the Trust C Subordinated Debentures owned by the
Trust C Issuer, and each US Holder will be required to include all income or
gain recognized for United States federal income tax purposes with respect to
its allocable share of the Trust C Subordinated Debentures on its own income tax
return.
 
  Characterization of the Trust C Subordinated Debentures
 
     The Corporation and the Trust C Issuer have agreed to treat the Trust C
Subordinated Debentures as indebtedness for all United States federal income tax
purposes. In connection with the issuance of the Trust C Subordinated
Debentures, Tax Counsel will render its opinion generally to the effect that,
under then current law and based on the representations, facts and assumptions
set forth in this Prospectus Supplement, and assuming full compliance with the
terms of the Indenture (and other relevant documents), and based on certain
assumptions and qualifications referenced in the opinion, the Trust C
Subordinated Debentures will be characterized for United States federal income
tax purposes as debt of the Corporation.
 
  Interest Income and Original Issue Discount
 
     Under the terms of the Trust C Subordinated Debentures, the Corporation has
the ability to defer payments of interest from time to time by extending the
interest payment period for a period not exceeding 20 consecutive quarterly
periods, but not beyond the maturity of the Trust C Subordinated Debentures.
Treasury regulations under Section 1273 of the Code provide that debt
instruments like the Trust C Subordinated Debentures will not be considered
issued with original issue discount ("OID") by reason of the Corporation's
ability to defer payments of interest if the likelihood of such deferral is
"remote."
 
     The Corporation has concluded, and this discussion assumes, that, as of the
date of this Prospectus Supplement the likelihood of deferring payments of
interest under the terms of the Trust C Subordinated Debentures is "remote"
within the meaning of the applicable Treasury regulations, in part because
exercising that
 
                                      S-22
<PAGE>   23
 
option would prevent the Corporation from declaring dividends on its stock and
would prevent the Corporation from making any payments with respect to debt
securities that rank pari passu with or junior to the Trust C Subordinated
Debentures. Therefore, the Trust C Subordinated Debentures should not be treated
as issued with OID by reason of the Corporation's deferral option. Consequently,
stated interest on the Trust C Subordinated Debentures will generally be taxable
to a US Holder as ordinary income when paid or accrued in accordance with that
holder's method of accounting for income tax purposes. It should be noted,
however, that these regulations may in the future be analyzed and interpreted by
the IRS in rulings or other published documents. Accordingly, it is possible
that the IRS could take a position contrary to the interpretation described
herein.
 
     In the event the Corporation exercises its option to defer payments of
interest, the Trust C Subordinated Debentures would be treated as reissued for
OID purposes. All remaining interest payments (and any de minimis OID) on the
Trust C Subordinated Debentures would thereafter be treated as OID, which would
accrue, and be includible in a US Holder's taxable income, (regardless of the US
Holder's method of accounting for income tax purposes) over the remaining term
of the Trust C Subordinated Debentures (including any period of interest
deferral). The accrual of OID on the Trust C Subordinated Debentures would be
determined by treating the reissued Trust C Subordinated Debentures as if they
had a fixed interest rate equal to their variable rate on the date they are
reissued and an issue price equal to their adjusted issue price on that date.
The amount of OID in each period would first be calculated on an economic
accrual basis based on the fixed interest rate. The OID accrual would be
adjusted (up or down) based on the actual accural of interest on the Trust C
Subordinated Debentures during each period. Consequently, during any period of
interest deferral, US Holders will include OID in gross income in advance of the
receipt of cash, and a US Holder which disposes of a Trust C Capital Security
prior to the record date for payment of distributions on the Trust C
Subordinated Debentures following that period will be subject to income tax on
OID accrued through the date of disposition (and not previously included in
income), but will not receive cash from the Trust C Issuer with respect to such
OID.
 
     If the possibility of the Corporation's exercise of its option to defer
payments of interest was not remote, the Trust C Subordinated Debentures would
be treated as initially issued with OID in an amount equal to the aggregate
interest (plus any de minimis OID) over the term of the Trust C Subordinated
Debentures. That OID would generally be includible in a US Holder's taxable
income, over the term of the Trust C Subordinated Debentures, in the manner
described above.
 
  Characterization of Income
 
     Because the income underlying the Trust C Capital Securities will not be
characterized as dividends for income tax purposes, corporate holders of the
Trust C Capital Securities will not be entitled to a dividends-received
deduction for any income recognized with respect to the Trust C Capital
Securities.
 
  Market Discount and Bond Premium
 
     US Holders of Trust C Capital Securities may be considered to have acquired
their undivided interest in the Trust C Subordinated Debentures with market
discount or acquisition premium (as each phrase is defined for United States
federal income tax purposes).
 
  Receipt of Trust C Subordinated Debentures or Cash Upon Liquidation of the
Trust C Issuer
 
     Under certain circumstances described herein (see "Certain Terms Trust C
Securities--Liquidation Distribution Upon Dissolution"), the Trust C Issuer may
distribute the Trust C Subordinated Debentures to holders in exchange for the
Trust C Capital Securities and in liquidation of the Trust C Issuer. Except as
discussed below, such a distribution would not be a taxable event for United
States federal income tax purposes, and each US Holder would have an aggregate
adjusted basis in its Trust C Subordinated Debentures for United States federal
income tax purposes equal to such holder's aggregate adjusted basis in its Trust
C Capital Securities. For United States federal income tax purposes, a US
Holder's holding period in the Trust C Subordinated Debentures received in such
a liquidation of the Trust C Issuer would include the period during which the
Trust C Capital Securities were held by the holder. If, however, the relevant
event is a Tax Event which results in the Trust C Issuer being treated as an
association taxable as a corporation, the distribution would likely
 
                                      S-23
<PAGE>   24
 
constitute a taxable event to US Holders of the Trust C Capital Securities for
United States federal income tax purposes.
 
     Under certain circumstances described herein (see "Certain Terms of Trust C
Capital Securities"), the Trust C Subordinated Debentures may be redeemed for
cash and the proceeds of such redemption distributed to holders in redemption of
their Trust C Capital Securities. Such a redemption would be taxable for United
States federal income tax purposes, and a US Holder generally would recognize
gain or loss as if it had sold the Trust C Capital Securities for cash. See
"--Sales of Trust C Capital Securities" below.
 
  Sales of Trust C Capital Securities
 
     A US Holder that sells Trust C Capital Securities will recognize gain or
loss equal to the difference between its adjusted basis in the Trust C Capital
Securities and the amount realized on the sale of such Trust C Capital
Securities. A US Holder's adjusted basis in the Trust C Capital Securities
generally will be its initial purchase price, increased by OID previously
included (or currently includible) in such holder's gross income to the date of
disposition, and decreased by payments received on the Trust C Capital
Securities (other than any interest received with respect to the period prior to
the effective date of the Corporation's first exercise of its option to defer
payments of interest). Any such gain or loss generally will be capital gain or
loss, and generally will be a long-term capital gain or loss if the Trust C
Capital Securities have been held for more than one year prior to the date of
disposition. United States federal income tax rates on long-term capital gain
received by individuals vary based on the individual's income and the holding
period for the asset. In particular, different maximum tax rates apply to gains
recognized by an individual from the sale of (i) assets held for more than one
year but no more than 18 months and (ii) assets held for more than 18 months.
Holders should contact their tax advisors for more information or for the
capital gains tax rate applicable to particular Trust C Capital Securities.
 
     A holder who disposes of his Trust C Capital Securities between record
dates for payments of distributions thereon will be required to include accrued
but unpaid interest (or OID) on the Trust C Subordinated Debentures through the
date of disposition in its taxable income for United States federal income tax
purposes (notwithstanding that the holder may receive a separate payment from
the purchaser with respect to accrued interest), and to deduct that amount from
the sales proceeds received (including the separate payment, if any, with
respect to accrued interest) for the Trust C Capital Securities (or as to OID
only, to add such amount to such holder's adjusted tax basis in its Trust C
Capital Securities). To the extent the selling price is less than the holder's
adjusted tax basis (which will include accrued but unpaid OID, if any), a holder
will recognize a capital loss. Subject to certain limited exceptions, capital
losses cannot be applied to offset ordinary income for United States federal
income tax purposes.
 
PENDING TAX LITIGATION AFFECTING THE TRUST C CAPITAL SECURITIES
 
     Recently, a taxpayer filed a petition in the United States Tax Court
contesting the IRS' proposed disallowance of interest deductions the taxpayer
claimed in respect to securities issued in 1993 and 1994 that are, in some
respects, similar to the Trust C Capital Securities of the Trust C Issuer.
(Enron Corp. v. Commissioner, Docket No. 6149-98, filed April 1, 1998). It is
possible that an adverse decision by the Tax Court concerning the deductibility
of such interest could give rise to a Tax Event. Such a Tax Event would give the
Corporation the right to redeem the Trust C Subordinated Debentures. See
"Certain Terms of Trust C Subordinated Debentures--Redemption" and "Certain
Terms of Trust C Capital Securities--Liquidation Distribution Upon Dissolution."
 
NON-US HOLDERS
 
     The following discussion applies to a Non-US Holder.
 
     Payments to a holder of a Trust C Capital Security which is a Non-US Holder
will generally not be subject to withholding of income tax, provided that (a)
the beneficial owner of the Trust C Capital Security does not (directly or
indirectly, actually or constructively) own 10% or more of the total combined
voting power of all classes of stock of the Corporation entitled to vote, (b)
the beneficial owner of the Trust C Capital Security is not a controlled foreign
corporation that is related to the Corporation through stock ownership, and (c)
either (i) the beneficial owner of the Trust C Capital Securities certifies to
the Trust C Issuer or its agent, under penalties of
                                      S-24
<PAGE>   25
 
perjury, that it is a Non-US Holder and provides its name and address, or (ii) a
securities clearing organization, bank or other financial institution that holds
customers' securities in the ordinary course of its trade or business (a
"Financial Institution"), and holds the Trust C Capital Security in such
capacity, certifies to the Trust C Issuer or its agent, under penalties of
perjury, that such a statement has been received from the beneficial owner by it
or by another Financial Institution between it and the beneficial owner in the
chain of ownership, and furnishes the Trust C Issuer or its agent with a copy
thereof.
 
     A Non-US Holder of a Trust C Capital Security will generally not be subject
to withholding of income tax on any gain realized upon the sale or other
disposition of a Trust C Capital Security.
 
     A Non-US Holder which holds the Trust C Capital Securities in connection
with the active conduct of a United States trade or business will be subject to
income tax on all income and gains recognized with respect to its proportionate
share of the Trust C Subordinated Debentures.
 
INFORMATION REPORTING
 
     In general, information reporting requirements will apply to payments made
on, and proceeds from the sale of, the Trust C Capital Securities held by a
noncorporate US Holder within the United States. In addition, payments made on,
and payments of the proceeds from the sale of, the Trust C Capital Securities to
or through the United States office of a broker or through certain U.S.-related
financial intermediaries are subject to information reporting unless the holder
thereof certifies as to its Non-United States status or otherwise establishes an
exemption from information reporting and backup withholding. See "--Backup
Withholding." Taxable income on the Trust C Capital Securities for a calendar
year should be reported to US Holders on the appropriate form by the following
January 31st.
 
BACKUP WITHHOLDING
 
     Payments made on, and proceeds from the sale of, the Trust C Capital
Securities may be subject to a "backup" withholding tax of 31% unless the holder
complies with certain identification or exemption requirements. Any amounts so
withheld will be allowed as a credit against the holder's income tax liability,
or refunded, provided the required information is provided to the IRS.
 
     THE PRECEDING DISCUSSION IS ONLY A SUMMARY AND DOES NOT ADDRESS THE
CONSEQUENCES TO A PARTICULAR HOLDER OF THE PURCHASE, OWNERSHIP AND DISPOSITION
OF THE TRUST C CAPITAL SECURITIES. POTENTIAL HOLDERS OF THE TRUST C CAPITAL
SECURITIES ARE URGED TO CONTACT THEIR OWN TAX ADVISORS TO DETERMINE THEIR
PARTICULAR TAX CONSEQUENCES.
 
                          CERTAIN ERISA CONSIDERATIONS
 
     Before authorizing an investment in the Trust C Capital Securities,
fiduciaries of pension, profit sharing, or other employee benefit plans subject
to ERISA ("Plans") should consider, among other matters: (a) ERISA's fiduciary
standards (including its prudence and diversification requirements), (b) whether
such fiduciaries have authority to make such investment in the Trust C Capital
Securities under the applicable Plan investment policies and governing
instruments, and (c) rules under ERISA and the Code that prohibit Plan
fiduciaries from causing a Plan to engage in a "prohibited transaction."
 
     Section 406 of ERISA and Section 4975 of the Code prohibit Plans, as well
as individual retirement accounts and Keogh plans subject to Section 4975 of the
Code (also "Plans"), from, among other things, engaging in certain transactions
involving "plan assets" with persons who are "parties in interest" under ERISA
or "disqualified persons" under the Code ("Parties in Interest") with respect to
such Plan. A violation of these "prohibited transaction" rules may result in an
excise tax or other liabilities under ERISA and/or Section 4975 of the Code for
such persons, unless exemptive relief is available under an applicable statutory
or administrative exemption. Employee benefit plans that are governmental plans
(as defined in Section 3(32) of ERISA), certain church plans (as defined in
Section 3(33) of ERISA) and foreign plans (as described in Section 4(b)(4) of
ERISA) are not subject to the requirements of ERISA or Section 4975 of the Code.
 
                                      S-25
<PAGE>   26
 
     The Department of Labor (the "DOL") has issued a regulation (29 C.F.R.
section 2510.3-101) (the "Plan Assets Regulation") concerning the definition of
what constitutes the assets of a Plan. The Plan Assets Regulation provides that,
as a general rule, the underlying assets and properties of corporations,
partnerships, trusts and certain other entities in which a Plan makes an
"equity" investment will be deemed, for purposes of ERISA, to be assets of the
investing Plan unless certain exceptions apply.
 
     Pursuant to an exception contained in the Plan Assets Regulation, the
assets of the Trust C Issuer would not be deemed to be "plan assets" of
investing Plans if, immediately after the most recent acquisition of any equity
interest in the Trust C Issuer less than 25% of the value of each class of
equity interests in the Trust C Issuer were held by Plans, other employee
benefit plans not subject to ERISA or Section 4975 of the Code (such as
governmental, church or foreign plans), and entities holding assets deemed to be
"plan assets" of any Plan (collectively, "Benefit Plan Investors"). No assurance
can be given that the value of the Trust C Capital Securities held by Benefit
Plan Investors will be less than 25% of the total value of such Trust C Capital
Securities at the completion of the initial offering or thereafter, and no
monitoring or other measures will be taken with respect to the satisfaction of
the conditions of this exception. All the Trust C Common Securities will be
purchased and held directly by the Corporation.
 
     Under another exception contained in the Plan Assets Regulation, if the
Trust C Capital Securities were to qualify as "publicly offered securities"
under the Plan Assets Regulation, the assets of the Trust C Issuer would not be
deemed to be "plan assets" by reason of a Plan's acquisition or holding of such
securities. The Trust C Capital Securities would qualify as "publicly offered
securities" if, among other things, they are offered pursuant to an effective
registration statement, are owned by 100 or more investors independent of the
issuer and each other at the time of the offering, and are subsequently
registered under the Exchange Act. It is expected that the 100 investor
requirement will not be satisfied and that the Trust C Capital Securities will
not be registered under the Exchange Act.
 
     There can be no assurance that any of the exceptions set forth in the Plan
Assets Regulation will apply to the purchase of Trust C Capital Securities
offered hereby and, as a result, an investing Plan's assets could be considered
to include an undivided interest in the Trust C Subordinated Debentures held by
the Trust C Issuer. In the event that assets of the Trust C Issuer are
considered assets of an investing Plan, the Issuer Trustees, the Corporation
and/or other persons, in providing services with respect to the Trust C
Subordinated Debentures, could be considered fiduciaries to such Plan and
subject to the fiduciary responsibility provisions of Title 1 of ERISA. In
addition, certain transactions involving the Trust C Issuer and/or the Trust C
Capital Securities could be deemed to constitute direct or indirect prohibited
transactions under ERISA and Section 4975 of the Code with respect to a Plan.
For example, if the Corporation is a Party in Interest with respect to an
investing Plan (either directly or by reason of its ownership of the Banks or
other subsidiaries), extensions of credit between the Corporation and the Trust
C Issuer (as represented by the Trust C Subordinated Debentures and the Trust C
Guarantee) would likely be prohibited by Section 406(a)(1)(B) of ERISA and
Section 4975(c)(1)(B) of the Code.
 
     The DOL has issued five prohibited transaction class exemptions ("PTCEs")
that may provide exemptive relief for direct or indirect prohibited transactions
resulting from the purchase or holding of the Trust C Capital Securities,
assuming that assets of the Trust C Issuer were deemed to be "plan assets" of
Plans investing in the Trust C Issuer (see above). Those class exemptions are
PTCE 96-23 (for certain transactions determined by in-house asset managers),
PTCE 91-38 (for certain transactions involving bank collective investment
funds), PTCE 95-60 (for certain transactions involving insurance company general
accounts), PTCE 90-1 (for certain transactions involving insurance company
pooled separate accounts), and PTCE 84-14 (for certain transactions determined
by independent qualified asset managers).
 
     Because of ERISA's prohibitions and those of Section 4975 of the Code, the
Trust C Capital Securities may not be purchased or held by any Plan, any entity
whose underlying assets include "plan assets" by reason of any Plan's investment
in the entity (a "Plan Asset Entity") or any other person investing "plan
assets" of any Plan, unless such purchase or holding is covered by the exemptive
relief provided by PTCE 96-23, 95-60, 91-38, 90-1 or 84-14 or another applicable
exemption. If a purchaser or holder of the Trust C Capital Securities that is a
Plan or a Plan Asset Entity elects to rely on an exemption other than PTCE
96-23, 95-60, 91-38, 90-1 or 84-14, the Corporation and the Trust C Issuer may
require a satisfactory opinion of counsel or other evidence with respect to
 
                                      S-26
<PAGE>   27
 
the availability of such exemption for such purchase and holding. Any purchaser
or holder of the Trust C Capital Securities that is a Plan or a Plan Assets
Entity or is purchasing such securities on behalf of or with "plan assets" will
be deemed to have represented by its purchase and holding thereof that (a) the
purchase and holding of the Trust C Capital Securities is covered by the
exemptive relief provided by PTCE 96-23, 95-60, 91-38, 90-1 or 84-14 or another
applicable exemption, (b) the Corporation and the Administrators are not
"fiduciaries," within the meaning of Section 3(21) of ERISA and the regulations
thereunder, with respect to such person's interest in the Trust C Capital
Securities or the Trust C Subordinated Debentures, and (c) such person approves
the purchase of the Trust C Subordinated Debentures and the appointment of the
Issuer Trustees.
 
     Any plans or other entities whose assets include Plan assets subject to
ERISA or Section 4975 of the Code proposing to acquire Trust C Capital
Securities should consult with their own counsel.
 
     Governmental Plans and certain church plans are not subject to ERISA, and
are also not subject to the prohibited transaction provisions of Section 4975 of
the Code. However, state laws or regulations governing the investment and
management of the assets of such plans may contain fiduciary and prohibited
transaction provisions similar to those under ERISA and the Code discussed
above. Accordingly, fiduciaries of governmental and church plans, in
consultation with their advisers, should consider the impact of their respective
state laws on investments in the Trust C Capital Securities and the
considerations discussed above to the extent applicable.

     Under the terms and conditions of the Underwriting Agreement, the
Underwriters are committed to take and pay for all of the Trust C Capital
Securities if any are taken.
 
     The Underwriters propose initially to offer the Trust C Capital Securities
in part directly to the public at the initial public offering price set forth on
the cover page of this Prospectus Supplement and in part to certain securities
dealers at such price less a concession not in excess of $6.00 per Trust C
Capital Security. The Underwriters may allow, and such dealers may reallow, a
concession not to exceed $2.50 per Trust C Capital Security to certain brokers
and dealers. After the Trust C Capital Securities are released for sale to the
public, the initial public offering price and other selling terms may from time
to time be varied by the Underwriters.
 
     In view of the fact that the proceeds from the sale of the Trust C Capital
Securities will be used to purchase the Trust C Subordinated Debentures issued
by the Corporation, the Underwriting Agreement provides that the Corporation
will pay an amount of $10.00 per Trust C Capital Security for the accounts of
the several Underwriters as compensation for the Underwriters' arranging the
investment therein of such proceeds.
 
     The Corporation and the Trust C Issuer have agreed that, during the period
beginning from the date of the Underwriting Agreement and continuing to and
including the closing date, they will not offer, sell, contract to sell or
otherwise dispose of any Trust C Capital Securities, any other beneficial
interests in the assets of the Trust C Issuer, or any preferred securities or
any other securities of the Trust C Issuer, the Corporation or any other trust
which are substantially similar to the Trust C Capital Securities, including any
guarantee of such securities, or any securities convertible into or exchangeable
for or representing the right to receive any such securities, without the prior
written consent of Salomon Brothers Inc, as representative of the Underwriters,
except for the Trust C Capital Securities offered in connection with this
offering.

     The Trust C Capital Securities are a new issue of securities with no
established trading market. The Corporation has been advised by the Underwriters
that the Underwriters intend to make a market in the Trust C Capital Securities
but are not obligated to do so and may discontinue market making at any time
without notice. No assurances can be given as to the liquidity of the trading
market for the Trust C Capital Securities.
 
     The Corporation and the Trust C Issuer have agreed to indemnify the several
Underwriters against certain liabilities, including liabilities under the
Securities Act.
 
     It is expected that delivery of the Trust C Capital Securities will be made
against payment therefor on or about June 9, 1998, as agreed upon by the
Corporation, the Trust C Issuer and the Underwriters in accordance with Rule
15c6-1 under the Exchange Act.
 
     Certain of the Underwriters or their affiliates have provided from time to
time, and expect to provide in the future, investment or commercial banking
services to the Corporation and its affiliates, for which such Underwriters or
their affiliates have received or will receive customary fees and commissions.
 
     In connection with this offering and in compliance with applicable law, the
Underwriters may over-allot (i.e., sell more Trust C Capital Securities than the
total amount shown on the list of Underwriters and participations which appears
above) and may effect transactions which stabilize, maintain or otherwise affect
the market price of the Trust C Capital Securities at levels above those which
might otherwise prevail in the open market. Such transactions may include
placing bids for the Trust C Capital Securities or effecting purchases of the
Trust C Capital Securities for the purpose of pegging, fixing or maintaining the
price of the Trust C Capital Securities or for the purpose of reducing a
syndicate short position created in connection with the offering. In addition,
the contractual arrangements among the Underwriters include a provision whereby,
if an Underwriter purchases Trust C Capital Securities in the open market for
the account of the underwriting syndicate and the securities purchased can be
traced to a particular Underwriter or member of the selling group, the
underwriting syndicate may require the Underwriter or selling group member in
question to purchase the Trust C Capital Securities in question at the cost
price to the syndicate or may recover from (or decline to pay to) the
Underwriter or selling group member in question the selling concession
applicable to the securities in question. The Underwriters are not required to
engage in any of these activities and any such activities, if commenced, may be
discontinued at any time.
 
                             VALIDITY OF SECURITIES
 
     Certain matters of Delaware law relating to the validity of the Trust C
Capital Securities, the enforceability of the Trust C Trust Agreement and the
formation of the Trust C Issuer will be passed upon by Richards, Layton &
Finger, special Delaware counsel to the Corporation and the Trust C Issuer. The
validity of the Trust C Guarantee and the Trust C Subordinated Debentures will
be passed upon for the Corporation by John F. Fulgoney, Senior Counsel to the
Corporation and for the Underwriters by Cravath, Swaine & Moore. As of March 31,
1998, Mr. Fulgoney was the beneficial owner of approximately 4,421 shares of
common stock, par value $5 per share, of the Corporation under the Corporation's
employee plans. Mr. Fulgoney also holds unexercised options granted under the
Corporation's stock option and incentive plans to purchase 24,800 shares of such
common stock. Mr. Fulgoney and Cravath, Swaine & Moore will rely on the opinion
of Richards, Layton & Finger as to matters of Delaware law. Certain matters
relating to United States federal income tax considerations described in this
Prospectus Supplement will be passed upon for the Corporation by Arnold &
Porter.

    FULLY AND UNCONDITIONALLY GUARANTEED, TO THE EXTENT DESCRIBED HEREIN, BY
 
                                 PNC BANK CORP.
 
    PNC Bank Corp., a Pennsylvania corporation (the "Corporation"), may from
time to time offer in one or more series or issuances its junior subordinated
deferrable interest debentures (the "Junior Subordinated Debentures"). The
Junior Subordinated Debentures will be unsecured and subordinate and junior in
right of payment to Senior Indebtedness (as defined in "Description of Junior
Subordinated Debentures -- Subordination") of the Corporation. As provided in an
accompanying Prospectus Supplement, the Corporation will have the right to defer
payments of interest on any series of Junior Subordinated Debentures by
extending the interest payment period thereon at any time or from time to time
for up to such number of consecutive interest payment periods (which shall not
extend beyond the Stated Maturity (as defined herein) of the Junior Subordinated
Debentures) with respect to each deferral period as may be specified in such
Prospectus Supplement (each, an "Extension Period"). In such circumstance,
however, the Corporation would not be permitted, subject to certain exceptions
set forth herein, to declare or pay any dividends, distributions or other
payments with respect to, or repay, repurchase, redeem or otherwise acquire, the
Corporation's capital stock or debt securities that rank pari passu with or
junior to such series of Junior Subordinated Debentures. See "Description of
Junior Subordinated Debentures -- Option to Defer Interest Payments" and "--
Restrictions on Certain Payments."
 
    PNC Capital Trust C, PNC Capital Trust D, PNC Capital Trust E and PNC
Capital Trust F (each, an "Issuer Trust"), each a statutory business trust
formed under the laws of the State of Delaware, may severally offer, from time
to time, preferred securities (the "Capital Securities") representing preferred
beneficial ownership interests in such Issuer Trust. The Corporation will be the
owner of the common securities (the "Common Securities" and, together with the
Capital Securities, the "Trust Securities") representing common beneficial
ownership interests in such Issuer Trust. Holders of the Capital Securities will
be entitled to receive preferential cumulative cash distributions
("Distributions") accumulating from the date of original issuance and payable
periodically as specified in an accompanying Prospectus Supplement.
 
    Concurrently with the issuance by an Issuer Trust of its Capital Securities,
such Issuer Trust will invest the proceeds thereof and of contributions received
in respect of the Common Securities in a corresponding series of the
Corporation's Junior Subordinated Debentures (the "Corresponding Junior
Subordinated Debentures") with terms corresponding to the terms of that Issuer
Trust's Capital Securities (the "Related Capital Securities"). Accordingly, if,
as provided in an accompanying Prospectus Supplement, the Corporation has the
right to defer the payment of interest on a series of Corresponding Junior
Subordinated Debentures, then, if interest payments are so deferred,
Distributions on the Related Capital Securities would also be deferred, but
would continue to accumulate at the rate per annum set forth in the related
Prospectus Supplement. See "Description of Capital Securities -- Distributions."
 
    Taken together, the Corporation's obligations under each series of
Corresponding Junior Subordinated Debentures, the Indenture, the related Trust
Agreement and the related Guarantee (each, as defined herein), in the aggregate,
will provide a full, irrevocable and unconditional guarantee of payments of
Distributions and other amounts due on the Related Capital Securities. See
"Relationship Among the Capital Securities, the Corresponding Junior
Subordinated Debentures and the Guarantees -- Full and Unconditional Guarantee."
The payment of Distributions with respect to the Capital Securities of each
Issuer Trust and payments on liquidation of such Issuer Trust or redemption of
such Capital Securities, in each case out of funds held by such Issuer Trust,
will be irrevocably guaranteed by the Corporation to the extent described herein
(each a "Guarantee"). See "Description of Guarantees." The obligations of the
Corporation under each Guarantee will be unsecured and subordinate and junior in
right of payment to all Senior Indebtedness of the Corporation.

(Cover page continued)
 
     The Corresponding Junior Subordinated Debentures will be the sole assets of
each Issuer Trust, and payments under the Corresponding Junior Subordinated
Debentures will be the only revenue of each Issuer Trust. If so provided in an
accompanying Prospectus Supplement, the Corporation may, upon receipt of
approval of the Board of Governors of the Federal Reserve System (the "Federal
Reserve") (if such approval is then required under the Federal Reserve's
applicable capital guidelines or policies), redeem the Corresponding Junior
Subordinated Debentures (and thereby cause the redemption of the Trust
Securities) or may terminate each Issuer Trust and, after satisfaction of
liabilities to the creditors of such Issuer Trust as required by applicable law,
cause the Corresponding Junior Subordinated Debentures to be distributed to the
holders of Related Capital Securities in exchange therefor upon liquidation of
their interests in such Issuer Trust. See "Description of Capital Securities --
Liquidation Distribution Upon Termination."
 
     The Junior Subordinated Debentures and Capital Securities may be offered in
amounts, at prices and on terms to be determined at the time of offering;
provided however, the aggregate initial public offering price of all Junior
Subordinated Debentures (other than Corresponding Junior Subordinated
Debentures) and Capital Securities (including the Corresponding Junior
Subordinated Debentures) issued pursuant to the Registration Statement of which
this Prospectus forms a part shall not exceed $600,000,000. Certain specific
terms of the Junior Subordinated Debentures or Capital Securities in respect of
which this Prospectus is being delivered will be described in an accompanying
Prospectus Supplement, including without limitation and where applicable and to
the extent not set forth herein, (a) in the case of Junior Subordinated
Debentures, the specific designation, aggregate principal amount, denominations,
Stated Maturity (including any provisions for the shortening or extension
thereof), interest payment dates, interest rate (which may be fixed or variable)
or method of calculating interest, if any, applicable Extension Period or
interest deferred terms, if any, place or places where principal, premium, if
any, and interest, if any, will be payable, any terms of redemption, any sinking
fund provisions, terms for any conversion or exchange into other securities,
initial offering or purchase price, methods of distribution and any other
special terms, and (b) in the case of Capital Securities, the identity of the
Issuer Trust, specific title, aggregate stated liquidation amount, number of
securities, Distribution rate or method of calculating such rate, Distribution
payment dates, applicable Distribution deferral terms, if any, place or places
where Distributions will be payable, any terms of redemption, exchange, initial
offering or purchase price, methods of distribution and any other special terms.
 
     The Prospectus Supplement also will contain information, as applicable,
about certain United States federal income tax consequences relating to the
Junior Subordinated Debentures and the Capital Securities.
 
     The Junior Subordinated Debentures and Capital Securities may be sold to or
through underwriters, through dealers, remarketing firms or agents or directly
to purchasers. See "Plan of Distribution." The names of any underwriters,
dealers, remarketing firms or agents involved in the sale of Junior Subordinated
Debentures or Capital Securities in respect of which this Prospectus is being
delivered and any applicable fee, commission or discount arrangements with them
will be set forth in a Prospectus Supplement. The Prospectus Supplement will
state whether the Junior Subordinated Debentures or Capital Securities will be
listed on any national securities exchange or automated quotation system. If the
Junior Subordinated Debentures or Capital Securities are not listed on any
national securities exchange or automated quotation system, there can be no
assurance that there will be a secondary market for the Junior Subordinated
Debentures or Capital Securities.
 
     This Prospectus may not be used to consummate sales of Junior Subordinated
Debentures or Capital Securities unless accompanied by a Prospectus Supplement.

Washington, D.C. 20549, at prescribed rates. In addition, the Commission
maintains a World Wide Web site that contains reports, proxy statements and
other information regarding registrants that file electronically, such as the

     The Corporation and the Issuer Trusts have filed with the Commission a
Registration Statement on Form S-3 (together with all amendments and exhibits
thereto, the "Registration Statement") under the Securities Act of 1933, as
amended (the "Securities Act"), with respect to the securities offered hereby.
This Prospectus does not contain all the information set forth in the
Registration Statement, certain portions of which have been omitted as permitted
by the rules and regulations of the Commission. For further information with
respect to the Corporation and the securities offered hereby, reference is made

notes and schedules filed as a part thereof or incorporated by reference
therein, which may be inspected at the public reference facilities of the

instance are qualified in all respects by reference to the copy of such document
filed as an exhibit to the Registration Statement.
 
     No separate financial statements of any Issuer Trust have been included
herein. The Corporation and the Issuer Trusts do not consider that such

operating history or independent operations and is not engaged in and does not
propose to engage in any activity other than holding Junior Subordinated
Debentures as trust assets and issuing the Trust Securities. See "The Issuer
Trusts," "Description of Capital Securities," "Description of Junior
Subordinated Debentures" and "Description of Guarantees." In addition, the
Corporation does not expect that any of the Issuer Trusts will be filing reports
under the Exchange Act with the Commission.

                                 PNC BANK CORP.
 
     The Corporation is a bank holding company registered under the Bank Holding
Company Act of 1956, as amended (the "BHC Act"). The Corporation 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, the Corporation has diversified its geographic presence
and product capabilities through strategic bank and nonbank acquisitions and the
formation of various nonbank subsidiaries.
 
     The Corporation is one of the largest diversified financial service
companies in the United States. The Corporation operates through seven lines of
business: National Consumer Banking, Private Banking, Secured Lending, Corporate
Banking, Regional Community Banking, Mortgage Banking and Asset Management and
Servicing. Each line of business focuses on specific customer segments and
offers financial products and services in the Corporation's primary geographic
markets in Pennsylvania, New Jersey, Delaware, Ohio and Kentucky and nationally
through retail distribution networks and alternative delivery channels. At March
31, 1998, the Corporation's consolidated assets, loans (net of unearned income),
deposits, and shareholders' equity were $72.4 billion, $53.6 billion, $46.1
billion and $5.5 billion, respectively.
 
     While the Corporation manages seven lines of business, the corporate legal
structure consists of 5 subsidiary banks and 111 nonbank subsidiaries. PNC Bank,
National Association, headquartered in Pittsburgh, Pennsylvania ("PNC Bank"), is
the Corporation's principal bank subsidiary. At December 31, 1997, PNC Bank had
total assets of $69.7 billion, representing approximately 93% of the
Corporation's consolidated assets.
 
     The Corporation's principal executive offices are located at One PNC Plaza,
249 Fifth Avenue, Pittsburgh, Pennsylvania 15222, and its telephone number is
(412) 762-1553.
 
                CONSOLIDATED RATIO OF EARNINGS TO FIXED CHARGES
 
     The following unaudited table presents the consolidated ratio of earnings
to fixed charges of the Corporation. 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.

                               THE ISSUER TRUSTS
 
     Each Issuer Trust is a statutory business trust formed under Delaware law
pursuant to (i) a trust agreement executed by the Corporation, as Depositor of
the Issuer Trust, and the Delaware Trustee and two Administrators (as defined
herein) of such Issuer Trust and (ii) the filing of a Certificate of Trust with
the Delaware Secretary of State on April 16, 1998. The trust agreement of each
Issuer Trust will be amended and restated in its entirety (each, as so amended
and restated, a "Trust Agreement") prior to the issuance of Capital Securities
by such Issuer Trust, substantially in the form filed as an exhibit to the
Registration Statement of which this Prospectus forms a part. Two individuals
will be selected by the holders of the Common Securities of each Issuer Trust to
act as administrators with respect to such Issuer Trust (the "Administrators").
The Corporation, while holder of the Common Securities of each Issuer Trust,
intends to select two individuals who are employees or officers of or affiliated
with the Corporation to serve as the Administrators. Each Issuer Trust exists
for the exclusive purposes of (i) issuing and selling the Trust Securities, (ii)
investing the gross proceeds of such Trust Securities in a Series of
Corresponding Junior Subordinated Debentures and (iii) engaging in only those
other activities necessary, convenient or incidental thereto. Accordingly, the
Corresponding Junior Subordinated Debentures will be the sole
 
                                        4
<PAGE>   33
 
assets of each Issuer Trust, and payments under the Corresponding Junior
Subordinated Debentures owned by an Issuer Trust will be the sole revenue of
such Issuer Trust.
 
     All of the Common Securities of each Issuer Trust will be owned directly or
indirectly by the Corporation. The Common Securities of an Issuer Trust will
rank pari passu, and payments will be made thereon pro rata, with the Capital
Securities of such Issuer Trust, except that upon the occurrence and
continuation of a Debenture Event of Default (as defined herein) arising as a
result of any failure by the Corporation to pay any amounts in respect of the
Junior Subordinated Debentures owned by such Issuer Trust when due, the rights
of the Corporation as holder of the Common Securities to payment in respect of
Distributions and payments upon liquidation, redemption or otherwise will be
subordinated to the rights of the holders of the Capital Securities of such
Issuer Trust. See "Description of Capital Securities -- Subordination of Common
Securities." Unless otherwise specified in the applicable Prospectus Supplement,
the Corporation will, directly or indirectly, acquire Common Securities in an
aggregate liquidation amount equal to at least 3% of the total capital of each
Issuer Trust.
 
     Unless otherwise specified in the applicable Prospectus Supplement, each
Issuer Trust will have a term of 55 years, but may dissolve earlier as provided
in the applicable Trust Agreement and described in the applicable Prospectus
Supplement. Unless otherwise specified in the applicable Prospectus Supplement,
the name and address of the Delaware Trustee for each Issuer Trust will be
Bankers Trust (Delaware), 1011 Centre Road, Suite 200, Wilmington, Delaware
19805, telephone number (302) 636-3305, and the name and address of the Property
Trustee, the Guarantee Trustee and the Debenture Trustee is Bankers Trust
Company, Four Albany Street, 4th Floor, New York, New York 10006, telephone
number (212) 250-2500. The Delaware Trustee and the Property Trustee are
collectively referred to herein as the "Issuer Trustees."
 
                                USE OF PROCEEDS
 
     Each Issuer Trust will use all proceeds received from the sale of the
Capital Securities to purchase Corresponding Junior Subordinated Debentures from
the Corporation. Except as otherwise set forth in the applicable Prospectus
Supplement, the Corporation intends to use the proceeds from the sale of its
Junior Subordinated Debentures (including Corresponding Junior Subordinated
Debentures issued to the Issuer Trusts in connection with the investment by the
Issuer Trusts of all of the proceeds from the sale of Trust Securities) for
general corporate purposes, which may include the repayment of indebtedness,
repurchases of outstanding common stock of the Corporation, investments in or
extensions of credit to its subsidiaries and/or the financing of possible
acquisitions. Pending such use, the net proceeds may be temporarily invested.
The precise amounts and timing of the application of proceeds will depend upon
the funding requirements of the Corporation and its subsidiaries and the
availability of other funds. In view of anticipated funding requirements, the
Corporation may from time to time engage in additional financings of a character
and in amounts to be determined.
 
                 DESCRIPTION OF JUNIOR SUBORDINATED DEBENTURES
 
     Junior Subordinated Debentures may be issued from time to time in one or
more series under a Junior Subordinated Indenture, as supplemented from time to
time (the "Indenture"), to be entered into by the Corporation and Bankers Trust
Company, as trustee (the "Debenture Trustee"). The terms of such Junior
Subordinated Debentures will include those stated in the Indenture, the form of
which is filed as an exhibit to the Registration Statement of which this
Prospectus forms a part, and those made part of the Indenture by the Trust
Indenture Act of 1939, as amended (the "Trust Indenture Act"). The following
summary of certain terms of the Indenture does not purport to be complete and is
subject in all respects to the provisions of, and is qualified in its entirety
by reference to, the Indenture and the Trust Indenture Act.
 
     Whenever particular provisions or defined terms in the Indenture are
referred to herein, such provisions or defined terms are incorporated by
reference herein.
 
GENERAL
 
     Each series of Junior Subordinated Debentures will rank pari passu with all
other series of Junior Subordinated Debentures heretofore or hereafter issued
pursuant to the Indenture, and will be unsecured and subordinate and junior in
right of payment to the extent and in the manner set forth in the Indenture to
all Senior Indebtedness (as defined below) of the Corporation. See "--
Subordination." Because the Corporation is
 
                                        5
<PAGE>   34
 
a holding company, the right of the Corporation to participate in any
distribution of assets of any subsidiary, including PNC Bank, upon such
subsidiary's liquidation or reorganization or otherwise, is subject to the prior
claims of creditors of the subsidiary, except to the extent the Corporation may
itself be recognized as a creditor of that subsidiary. Accordingly, the Junior
Subordinated Debentures will be effectively subordinated to all existing and
future liabilities of the Corporation's subsidiaries, and holders of Junior
Subordinated Debentures should look only to the assets of the Corporation for
payments on the Junior Subordinated Debentures. Except as otherwise provided in
the applicable Prospectus Supplement, the Indenture does not limit the
incurrence or issuance of other secured or unsecured debt of the Corporation,
including Senior Indebtedness, whether under the Indenture, any other existing
indenture or any other indenture that the Corporation may enter into in the
future or otherwise. See "-- Subordination" and the applicable Prospectus
Supplement relating to any offering of Capital Securities or Junior Subordinated
Debentures.
 
     The Junior Subordinated Debentures will be issuable in one or more series
pursuant to an indenture supplemental to the Indenture or a resolution of the
Corporation's Board of Directors or a committee thereof.
 
     The applicable Prospectus Supplement will describe the following terms of
the Junior Subordinated Debentures offered thereby: (1) the title of such Junior
Subordinated Debentures; (2) any limit upon the aggregate principal amount of
such Junior Subordinated Debentures; (3) the date or dates on which the
principal of such Junior Subordinated Debentures is payable (the "Stated
Maturity") or the method of determination thereof and any right of the
Corporation to shorten the Stated Maturity; (4) the rate or rates, if any, at
which such Junior Subordinated Debentures shall bear interest, the dates on
which any such interest shall be payable (the "Interest Payment Dates"), the
right, if any, of the Corporation to defer or extend an Interest Payment Date,
the record dates for any interest payable on any Interest Payment Date (the
"Regular Record Dates") and the method by which any of the foregoing shall be
determined; (5) the place or places where, subject to the terms of the Indenture
as described below under "-- Payment and Paying Agents," the principal of and
premium, if any, and interest on such Junior Subordinated Debentures will be
payable and where, subject to the terms of the Indenture as described below
under "-- Registration, Denomination and Transfer," such Junior Subordinated
Debentures may be presented for registration of transfer or exchange and the
place or places where notices and demands to or upon the Corporation in respect
of such Junior Subordinated Debentures and the Indenture may be made ("Place of
Payment"); (6) any period or periods within which, or date or dates on which,
the price or prices at which and the terms and conditions upon which such Junior
Subordinated Debentures may be redeemed, in whole or in part, at the option of
the Corporation or a holder thereof; (7) the obligation or the right, if any, of
the Corporation or a holder thereof to redeem, purchase or repay such Junior
Subordinated Debentures and the period or periods within which, the price or
prices at which, the currency or currencies (including currency unit or units)
in which and the other terms and conditions upon which such Junior Subordinated
Debentures shall be redeemed, repaid or purchased, in whole or in part, pursuant
to such obligation or right; (8) the denominations in which such Junior
Subordinated Debentures shall be issuable; (9) if other than in U.S. Dollars,
the currency or currencies (including currency unit or units) in which the
principal of and premium, if any, and interest, if any, on the Junior
Subordinated Debentures shall be payable, or in which such Junior Subordinated
Debentures shall be denominated; (10) any additions, modifications or deletions
in the events of default under the Indenture or in the covenants of the
Corporation specified in the Indenture with respect to such Junior Subordinated
Debentures; (11) if other than the principal amount thereof, the portion of the
principal amount of such Junior Subordinated Debentures that shall be payable
upon declaration of acceleration of the maturity thereof; (12) any additions or
changes to the Indenture with respect to such Junior Subordinated Debentures as
shall be necessary to permit or facilitate the issuance of such Junior
Subordinated Debentures in bearer form, registrable or not registrable as to
principal, and with or without interest coupons; (13) any index or indices used
to determine the amount of payments of principal of and premium, if any, on such
Junior Subordinated Debentures or the manner in which such amounts will be
determined; (14) the terms and conditions relating to the issuance of a
temporary Global Security representing all of such Junior Subordinated
Debentures and the exchange of such temporary Global Security for definitive
Junior Subordinated Debentures of such series; (15) subject to the terms
described herein under "-- Global Junior Subordinated Debentures," whether such
Junior Subordinated Debentures shall be issued in whole or in part in the form
of one or more Global Securities and, in such case, the depositary for such
Global Securities, which depositary shall be a clearing agency registered under
the Exchange Act; (16) the appointment of any paying agent or agents; (17) the
terms of any right of the Corporation or a holder to convert or
 
                                        6
<PAGE>   35
 
exchange such Junior Subordinated Debentures into Capital Securities; (18) the
form of Trust Agreement and Guarantee Agreement, if applicable; and (19) any
other terms of the Junior Subordinated Debentures not inconsistent with the
provisions of the Indenture.
 
     Junior Subordinated Debentures may be sold at a substantial discount below
their stated principal amount, bearing no interest or interest at a rate which
at the time of issuance is below market rates. Certain United States federal
income tax consequences and special considerations applicable to any such Junior
Subordinated Debentures will be described in the applicable Prospectus
Supplement.
 
     If the purchase price of any of the Junior Subordinated Debentures is
payable in one or more foreign currencies or currency units or if any Junior
Subordinated Debentures are denominated in one or more foreign currencies or
currency units or if the principal of, premium, if any, or interest on any
Junior Subordinated Debentures is payable in one or more foreign currencies or
currency units, the restrictions, elections, certain United States federal
income tax consequences, specific terms and other information with respect to
such series of Junior Subordinated Debentures and such foreign currency or
currency units will be set forth in the applicable Prospectus Supplement.
 
     If any index is used to determine the amount of payments of principal of,
premium, if any, or interest on any series of Junior Subordinated Debentures,
special United States federal income tax, accounting and other considerations
applicable thereto will be described in the applicable Prospectus Supplement.
 
REGISTRATION, DENOMINATION, AND TRANSFER
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
Junior Subordinated Debentures will be issuable only in registered form without
coupons. Junior Subordinated Debentures of any series will be exchangeable for
other Junior Subordinated Debentures of the same issue and series, of any
authorized denominations, of a like aggregate principal amount, of the same
original issue date and stated maturity and bearing the same interest rate.
 
     Junior Subordinated Debentures may be presented for exchange as provided
above, and may be presented for registration of transfer (with the form of
transfer endorsed thereon, or a satisfactory written instrument of transfer,
duly executed), at the office of the appropriate securities registrar or at the
office of any transfer agent designated by the Corporation for such purpose with
respect to any series of Junior Subordinated Debentures and referred to in the
applicable Prospectus Supplement, without service charge and upon payment of any
taxes and other governmental charges as described in the Indenture. The
Corporation will appoint the Debenture Trustee as securities registrar under the
Indenture. If the applicable Prospectus Supplement refers to any transfer agents
(in addition to the securities registrar) initially designated by the
Corporation with respect to any series of Junior Subordinated Debentures, the
Corporation may at any time rescind the designation of any such transfer agent
or approve a change in the location through which any such transfer agent acts,
provided that the Corporation maintains a transfer agent in each place of
payment for such series. The Corporation may at any time designate additional
transfer agents with respect to any series of Junior Subordinated Debentures.
 
     In the event of any redemption, neither the Corporation nor the Debenture
Trustee shall be required to (i) issue, register the transfer of or exchange
Junior Subordinated Debentures of any series during a period beginning at the
opening of business 15 days before the day of selection for redemption of Junior
Subordinated Debentures of that series and ending at the close of business on
the day of mailing of the relevant notice of redemption or (ii) transfer or
exchange any Junior Subordinated Debentures so selected for redemption, except,
in the case of any Junior Subordinated Debentures being redeemed in part, any
portion thereof not to be redeemed.
 
GLOBAL JUNIOR SUBORDINATED DEBENTURES
 
     The Junior Subordinated Debentures of a series may be issued in whole or in
part in the form of one or more Global Junior Subordinated Debentures that will
be deposited with or on behalf of a depositary (the "Depositary") identified in
the Prospectus Supplement relating to such series. Global Junior Subordinated
Debentures may be issued only in fully registered form and in either temporary
or permanent form. Unless and until it is exchanged in whole or in part for the
individual definitive Junior Subordinated Debentures represented thereby, a
Global Junior Subordinated Debenture may not be transferred except as a whole by
the Depositary for such Global Junior Subordinated Debenture to a nominee of
such Depositary or by a nominee of such Depositary
 
                                        7
<PAGE>   36
 
to such Depositary or another nominee of such Depositary or by the Depositary or
any nominee to a successor Depositary or any nominee of such successor.
 
     The specific terms of the depositary arrangement with respect to a series
of Junior Subordinated Debentures will be described in the Prospectus Supplement
relating to such series. The Corporation anticipates that the following
provisions will generally apply to depositary arrangements.
 
     Upon the issuance of a Global Junior Subordinated Debenture, and the
deposit of such Global Junior Subordinated Debenture with or on behalf of the
Depositary, the Depositary for such Global Junior Subordinated Debenture or its
nominee will credit, on its book-entry registration and transfer system, the
respective principal amounts of the individual Junior Subordinated Debentures
represented by such Global Junior Subordinated Debenture to the accounts of
persons that have accounts with such Depositary, which may include the accounts
of the operator of the Euroclear System ("Euroclear"), and Cedel Bank, societe
anonyme ("Cedel") ("Participants"). Such accounts shall be designated by the
dealers, underwriters or agents with respect to such Junior Subordinated
Debentures or by the Corporation if such Junior Subordinated Debentures are
offered and sold directly by the Corporation. Ownership of beneficial interests
in a Global Junior Subordinated Debenture will be limited to Participants or
persons that may hold interests through Participants, including Euroclear and
Cedel and their participants. Ownership of beneficial interests in such Global
Junior Subordinated Debenture will be shown on, and the transfer of that
ownership will be effected only through records maintained by the applicable
Depositary or its nominee (with respect to interests of Participants) and the
records of Participants (with respect to interests of persons who hold through
Participants). The laws of some states require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to transfer beneficial interests in
a Global Junior Subordinated Debenture.
 
     So long as the Depositary for a Global Junior Subordinated Debenture, or
its nominee, is the registered owner of such Global Junior Subordinated
Debenture, such Depositary or such nominee, as the case may be, will be
considered the sole owner or holder of the Junior Subordinated Debentures
represented by such Global Junior Subordinated Debenture for all purposes under
the Indenture. Except as provided below, owners of beneficial interest in a
Global Junior Subordinated Debenture will not be entitled to have any of the
individual Junior Subordinated Debentures of the series represented by such
Global Junior Subordinated Debenture registered in their names, will not receive
or be entitled to receive physical delivery of any such Junior Subordinated
Debentures of such series in definitive form and will not be considered the
owners or holders thereof under the Indenture.
 
     Payments of principal of and premium, if any, and interest on individual
Junior Subordinated Debentures represented by a Global Junior Subordinated
Debenture registered in the name of a Depositary or its nominee will be made to
the Depositary or its nominee, as the case may be, as the registered owner of
the Global Junior Subordinated Debenture representing such Junior Subordinated
Debentures. None of the Corporation, the Debenture Trustee, any Paying Agent, or
the Securities Registrar for such Junior Subordinated Debentures will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in the Global Junior
Subordinated Debenture representing such Junior Subordinated Debentures or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.
 
     The Corporation expects that the Depositary for a series of Junior
Subordinated Debentures or its nominee, upon receipt of any payment of
principal, premium, if any, or interest in respect of a permanent Global Junior
Subordinated Debenture representing any of such Junior Subordinated Debentures,
immediately will credit Participants' accounts with payments in amounts
proportionate to their respective beneficial interest in the principal amount of
such Global Junior Subordinated Debenture for such Junior Subordinated
Debentures as shown on the records of such Depositary or its nominee. The
Corporation also expects that payments by Participants will be governed by
standing instructions and customary practices, as is now the case with
securities held for the accounts of customers in bearer form or registered in
"street name." Such payments will be the responsibility of such Participants.
 
     Unless otherwise specified in the applicable Prospectus Supplement, if a
Depositary for a series of Junior Subordinated Debentures is at any time
unwilling, unable or ineligible to continue as depositary and a successor
depositary is not appointed by the Corporation within 90 days, the Corporation
will issue individual Junior
                                        8
<PAGE>   37
 
Subordinated Debentures of such series in exchange for the Global Junior
Subordinated Debenture representing such series of Junior Subordinated
Debentures. In addition, the Corporation may at any time and in its sole
discretion, subject to any limitations described in the Prospectus Supplement
relating to such Junior Subordinated Debentures, determine not to have any
Junior Subordinated Debentures of such series represented by one or more Global
Junior Subordinated Debentures and, in such event, will issue certificated
Junior Subordinated Debentures of such series in exchange for the Global Junior
Subordinated Debenture. Further, if the Corporation so specifies with respect to
the Junior Subordinated Debentures of a series, an owner of a beneficial
interest in a Global Junior Subordinated Debenture representing Junior
Subordinated Debentures of such series may, on terms acceptable to the
Corporation, the Debenture Trustee and the Depositary for such Global Junior
Subordinated Debenture, receive certificated Junior Subordinated Debentures of
such series in exchange for such beneficial interests, subject to any
limitations described in the Prospectus Supplement relating to such Junior
Subordinated Debentures. In any such instance, an owner of a beneficial interest
in a Global Junior Subordinated Debenture will be entitled to physical delivery
of certificated Junior Subordinated Debentures of the series represented by such
Global Junior Subordinated Debenture equal in aggregate principal amount to such
beneficial interest and to have such Junior Subordinated Debentures registered
in its name. Individual Junior Subordinated Debentures of such series so issued
will be issued in the denominations specified for such series in the applicable
Prospectus Supplement.
 
PAYMENT AND PAYING AGENTS
 
     Unless otherwise indicated in the applicable Prospectus Supplement, payment
of principal of and premium, if any, and any interest on Junior Subordinated
Debentures (other than any Junior Subordinated Debentures represented by Global
Junior Subordinated Debentures) will be made at the office of the Debenture
Trustee in the City of New York or at the office of such paying agent or paying
agents as the Corporation may designated from time to time, except that at the
option of the Corporation payment of any interest may be made (i) except in the
case of Global Junior Subordinated Debentures, by check mailed to the address of
the person entitled thereto as such address shall appear in the securities
register or (ii) in certain circumstances, by transfer to an account maintained
by the person entitled thereto as specified in the securities register, provided
that proper transfer instructions have been received by the Regular Record Date.
Unless otherwise indicated in the applicable Prospectus Supplement, payment of
any interest on Junior Subordinated Debentures will be made to the person in
whose name such Junior Subordinated Debentures are registered at the close of
business on the Regular Record Date for such interest, except in the case of
defaulted interest. The Corporation may at any time designate additional paying
agents or rescind the designation of any paying agent; however, the Corporation
will at all times be required to maintain a paying agent in each place of
payment for each series of Junior Subordinated Debentures.
 
     Any moneys deposited with the Debenture Trustee or any paying agent, or
then held by the Corporation in trust, for the payment of the principal of and
premium, if any, or interest on any Junior Subordinated Debenture and remaining
unclaimed for two years after such principal and premium, if any, or interest
has become due and payable shall, at the request of the Corporation, be repaid
to the Corporation and the holder of such Junior Subordinated Debenture shall
thereafter look, as a general unsecured creditor, only to the Corporation for
payment thereof.
 
OPTION TO DEFER INTEREST PAYMENTS
 
     As provided in the applicable Prospectus Supplement, so long as no
Debenture Event of Default has occurred and is continuing, the Corporation will
have the right at any time and from time to time during the term of any series
of Junior Subordinated Debentures to defer payment of interest for up to such
number of consecutive interest payment periods as may be specified in the
applicable Prospectus Supplement (each, an "Extension Period"), subject to the
terms, conditions and covenants, if any, specified in such Prospectus
Supplement, provided, that such Extension Period may not extend beyond the
Stated Maturity of such series of Junior Subordinated Debentures. Certain United
States federal income tax consequences and special considerations applicable to
any such Junior Subordinated Debentures will be described in the applicable
Prospectus Supplement.
 
                                        9
<PAGE>   38
 
REDEMPTION
 
     Unless otherwise indicated in the applicable Prospectus Supplement, Junior
Subordinated Debentures will not be subject to any sinking fund.
 
     Unless otherwise indicated in the applicable Prospectus Supplement, the
Corporation may, at its option and subject to receipt of prior approval by the
Federal Reserve if then required under applicable capital guidelines or
policies, redeem the Junior Subordinated Debentures of any series in whole at
any time or in part from time to time. If the Junior Subordinated Debentures of
any series are so redeemable only on or after a specified date or upon the
satisfaction of additional conditions, the applicable Prospectus Supplement will
specify such date or describe such conditions. Except as otherwise specified in
the applicable Prospectus Supplement, the redemption price for any Junior
Subordinated Debenture so redeemed shall equal any accrued and unpaid interest
thereon to the redemption date, plus 100% of the principal amount thereof plus
any redemption premium required to be paid thereon.
 
     Except as otherwise specified in the applicable Prospectus Supplement, if a
Tax Event, a Capital Treatment Event or Investment Company Event (each as
defined below) shall occur and be continuing, the Corporation may, at its option
and subject to receipt of prior approval by the Federal Reserve if then required
under applicable capital guidelines or policies, redeem such series of Junior
Subordinated Debentures in whole (but not in part) at any time within 90 days
following of the occurrence of such Tax Event, Capital Treatment Event or
Investment Company Event, at a redemption price equal to 100% of the principal
amount of such Junior Subordinated Debentures then outstanding plus accrued and
unpaid interest to the date fixed for redemption plus any redemption premium
required to be paid thereon.
 
     "Tax Event" with respect to an Issuer Trust means the receipt by the Issuer
Trust of a series of Capital Securities of an opinion of counsel experienced in
such matters to the effect that, as a result of any amendment to, or change
(including any announced prospective change) in, the laws (or any regulations
thereunder) of the United States or any political subdivision or taxing
authority thereof or therein, or as a result of any official administrative
pronouncement or action or judicial decision interpreting or applying such laws
or regulations, which amendment or change is effective or which pronouncement,
action or decision is announced on or after the date of issuance of such Capital
Securities, there is more than an insubstantial risk that (i) such Issuer Trust
is, or will be within 90 days of the delivery of such opinion, subject to United
States federal income tax with respect to income received or accrued on the
corresponding series of Corresponding Junior Subordinated Debentures, (ii)
interest payable by the Corporation on such series of Corresponding Junior
Subordinated Debentures is not, or within 90 days of the delivery of such
opinion, will not be, deductible by the Corporation, in whole or in part, for
United States federal income tax purposes, or (iii) such Issuer Trust is, or
will be within 90 days of the delivery of such opinion, subject to more than a
de minimis amount of other taxes, duties or other governmental charges.
 
     "Capital Treatment Event" means the reasonable determination by the
Corporation that, as a result of any amendment to, or change (including any
announced prospective change) in, the laws (or any rules or regulations
thereunder) of the United States or any political subdivision thereof or
therein, or as a result of any official or administrative pronouncement or
action or judicial decision interpreting or applying such laws or regulations,
which amendment or change is effective or such pronouncement, action or decision
is announced on or after the date of issuance of the applicable Capital
Securities, there is more than an insubstantial risk that the Corporation will
not be entitled to treat an amount equal to the Liquidation Amount (as defined
below) of the applicable Capital Securities as "Tier 1 Capital" (or the then
equivalent thereof), except as otherwise restricted under the 25% Capital
Limitation, for purposes of the capital adequacy guidelines of the Federal
Reserve, as then in effect and applicable to the Corporation.
 
     "Investment Company Event" with respect to an Issuer Trust means the
receipt by the Issuer Trust of an opinion of counsel to the Corporation
experienced in such manners to the effect that, as a result of the occurrence of
a change in law or regulation or a written change (including any announced
prospective change) in interpretation or application of law or regulation by any
legislative body, court, governmental agency or regulatory authority, there is
more than an insubstantial risk that such Issuer Trust is or will be considered
an "investment company" that is required to be registered under the Investment
Company Act of 1940, as amended
 
                                       10
<PAGE>   39
 
(the "Investment Company Act"), which change or prospective change becomes
effective or would become effective, as the case may be, on or after the date of
the issuance of the Capital Securities.
 
     "25% Capital Limitation" means the limitation imposed by the Federal
Reserve that the proceeds of certain qualifying securities similar to the Trust
Securities will qualify as Tier 1 capital of the issuer up to an amount not to
exceed 25% of the issuer's Tier 1 capital, or any subsequent limitation adopted
by the Federal Reserve.
 
     Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each holder of Junior Subordinated
Debentures to be redeemed at its registered address. Unless the Corporation
defaults in payment of the redemption price, on and after the redemption date,
interest will cease to accrue on such Junior Subordinated Debentures or portions
thereof called for redemption.
 
RESTRICTIONS ON CERTAIN PAYMENTS
 
     The Corporation will also covenant, as to each series of Junior
Subordinated Debentures, that it will not (i) declare or pay any dividends or
distributions on, or redeem, purchase, acquire or make a liquidation payment
with respect to, any of the Corporation's capital stock or (ii) make any payment
of principal, interest or premium, if any, on or repay or repurchase or redeem
any debt securities of the Corporation (including other series of Junior
Subordinated Debentures) that rank pari passu in all respects with or junior in
interest to the Junior Subordinated Debentures (other than (a) repurchases,
redemptions or other acquisitions of shares of capital stock of the Corporation
in connection with any employment contract, benefit plan or other similar
arrangement with or for the benefit of any one or more employees, officers,
directors or consultants, in connection with a dividend reinvestment or
stockholder stock purchase plan or in connection with the issuance of capital
stock of the Corporation (or securities convertible into or exercisable for such
capital stock) as consideration in an acquisition transaction entered into prior
to the applicable Extension Period or other event referred to below, (b) as a
result of an exchange or conversion of any class or series of the Corporation's
capital stock (or any capital stock of a subsidiary of the Corporation) for any
class or series of the Corporation's capital stock or of any class or series of
the Corporation's indebtedness for any class or series of the Corporation's
capital stock, (c) the purchase of fractional interests in shares of the
Corporation's capital stock pursuant to the conversion or exchange provisions of
such capital stock or the security being converted or exchanged, (d) any
declaration of a dividend in connection with any stockholder's rights plan, or
the issuance of rights, stock or other property under any stockholder's rights
plan, or the redemption or repurchase of rights pursuant thereto, or (e) any
dividend in the form of stock, warrants, options or other rights where the
dividend stock or the stock issuable upon exercise of such warrants, options or
other rights is the same stock as that on which the dividend is being paid or
ranks pari passu with or junior to such stock), if at such time (x) there has
occurred any event (1) of which the Corporation has actual knowledge that with
the giving of notice or the lapse of time, or both, would constitute a Debenture
Event of Default and (2) that the Corporation has not taken reasonable steps to
cure, (y) if the Junior Subordinated Debentures are held by the Issuer Trust,
the Corporation is in default with respect to its payment of any obligations
under the Guarantees or (z) the Corporation has given notice of its election of
an Extension Period as provided in the Indenture and has not rescinded such
notice, or such Extension Period, or any extension thereof, is continuing.
 
MODIFICATION OF INDENTURE
 
     From time to time the Corporation and the Debenture Trustee may, without
the consent of the holders of any series of Junior Subordinated Debentures,
amend, waive or supplement the provisions of the Indenture for specified
purposes, including, among other things, curing ambiguities, defects or
inconsistencies (provided that any such action does not materially adversely
affect the interests of the holders of any series of Junior Subordinated
Debentures or, in the case of Corresponding Junior Subordinated Debentures, the
holders of the Related Capital Securities so long as they remain outstanding)
and qualifying, or maintaining the qualification of, the Indenture under the
Trust Indenture Act. The Indenture contains provisions permitting the
Corporation and the Debenture Trustee, with the consent of the holders of not
less than a majority in principal amount of each outstanding series of Junior
Subordinated Debentures affected, to modify the Indenture in a manner adversely
affecting the rights of the holders of such series of the Junior Subordinated
Debentures in any material respect; provided, that no such modification may,
without the consent of the holder of each outstanding Junior Subordinated
Debenture so affected, (i) change the Stated Maturity of any series of Junior
Subordinated
 
                                       11
<PAGE>   40
 
Debentures (except as otherwise specified in the applicable Prospectus
Supplement), or reduce the principal amount thereof, or reduce the rate or
extend the time of payment of interest thereon or (ii) reduce the percentage of
principal amount of Junior Subordinated Debentures of any series, the holders of
which are required to consent to any such modification of the Indenture,
provided further that, in the case of Corresponding Junior Subordinated
Debentures, so long as any Related Capital Securities remain outstanding, no
such modification may be made that adversely affects the holders of such Capital
Securities in any material respect, and no termination of the Indenture may
occur, and no waiver of any event of default or compliance with any covenant
under the Indenture may be effective, without the prior consent of the holders
of at least a majority of the aggregate Liquidation Amount of all outstanding
Related Capital Securities affected unless and until the principal of and
premium, if any, on the Corresponding Junior Subordinated Debentures and all
accrued and unpaid interest thereon have been paid in full and certain other
conditions have been satisfied.
 
     In addition, the Corporation and the Debenture Trustee may execute, without
the consent of any holder of Junior Subordinated Debentures, any supplemental
Indenture for the purpose of creating any new series of Junior Subordinated
Debentures.
 
DEBENTURE EVENTS OF DEFAULT
 
     The Indenture provides that any one or more of the following described
events with respect to a series of Junior Subordinated Debentures that has
occurred and is continuing constitutes a "Debenture Event of Default" with
respect to such series of Junior Subordinated Debentures:
 
     (i)  failure for 30 days to pay any interest on such series of Junior
Subordinated Debentures when due (subject to the deferral of any due date in the
case of an Extension Period); or
 
     (ii) failure to pay any principal of or premium, if any, on such series of
Junior Subordinated Debentures when due whether at maturity or upon redemption
by declaration of acceleration or otherwise; or
 
     (iii) failure to observe or perform in any material respect certain other
covenants contained in the Indenture for 90 days after written notice to the
Corporation from the Debenture Trustee or the holders of at least 25% in
aggregate outstanding principal amount of such affected series of outstanding
Junior Subordinated Debentures; or
 
     (iv) certain events in bankruptcy, insolvency or reorganization of the
Corporation.
 
     The holders of a majority in aggregate outstanding principal amount of
Junior Subordinated Debentures of each series affected have the right to direct
the time, method and place of conducting any proceeding for any remedy available
to the Debenture Trustee. The Debenture Trustee or the holders of not less than
25% in aggregate outstanding principal amount of Junior Subordinated Debentures
of each series affected may declare the principal due and payable immediately
upon a Debenture Event of Default, and, in the case of Corresponding Junior
Subordinated Debentures, should the Debenture Trustee or such holders of such
Corresponding Junior Subordinated Debentures fail to make such declaration, the
holders of at least 25% in aggregate Liquidation Amount of the Related Capital
Securities shall have such right. The holders of a majority in aggregate
outstanding principal amount of Junior Subordinated Debentures of each series
affected may annul such declaration and waive the default if all defaults (other
than the non-payment of Junior Subordinated Debentures which have become due
solely by such acceleration) have been earned and a sum sufficient to pay all
matured installments of interest and principal due otherwise than by
acceleration has been deposited with the Debenture Trustee. In the case of
Corresponding Junior Subordinated Debentures, should the holders of such
Corresponding Junior Subordinated Debentures fail to annul such declaration and
waive such default, the holders of a majority in aggregate Liquidation Amount of
the Related Capital Securities affected shall have such right.
 
     The holders of a majority in aggregate outstanding principal amount of each
series of the Junior Subordinated Debentures affected thereby may, on behalf of
the holders of all the Junior Subordinated Debentures of such series, waive any
past default, except a default in the payment of principal or premium, if any,
or interest (unless such default has been cured and a sum sufficient to pay all
matured installments of interest and principal due otherwise than by
acceleration has been deposited with the Debenture Trustee) or a default in
respect of a covenant or provision which under the Indenture cannot be modified
or amended without the consent of the holder of each outstanding Junior
Subordinated Debenture. In the case of Corresponding Junior Subordinated
Debentures, should the holders of such Corresponding Junior Subordinated
Debentures fail to
 
                                       12
<PAGE>   41
 
waive such default, the holders of a majority in aggregate Liquidation Amount of
the Related Capital Securities affected shall have such right. The Corporation
is required to file annually with the Debenture Trustee a certificate as to
whether or not the Corporation is in compliance with all the conditions and
covenants applicable to it under the Indenture.
 
     If a Debenture Event of Default shall occur and be continuing as to a
series of Corresponding Junior Subordinated Debentures, the Property Trustee
will have the right to declare the principal of and the interest on such
Corresponding Junior Subordinated Debentures, and any other amounts payable
under the Indenture, to be forthwith due and payable and to enforce its other
rights as a creditor with respect to such Corresponding Junior Subordinated
Debentures.
 
ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF CAPITAL SECURITIES
 
     If a Debenture Event of Default with respect to a series of Junior
Subordinated Debentures has occurred and is continuing and such event is
attributable to the failure of the Corporation to pay interest or principal on
such Junior Subordinated Debentures on the date such interest or principal is
due and payable, a registered holder of Related Capital Securities may institute
a legal proceeding directly against the Corporation for enforcement of payment
to such holder of the principal of or interest on such Junior Subordinated
Debentures having a principal amount equal to the aggregate Liquidation Amount
of the Related Capital Securities of such holder (a "Direct Action"). The
Corporation may not amend the Indenture to remove the foregoing right to bring a
Direct Action without the prior written consent of the holders of all of the
Capital Securities outstanding. The Corporation shall have the right under the
Indenture to set-off any payment made to such holder of Capital Securities by
the Corporation in connection with a Direct Action.
 
     The holders of the Capital Securities will not be able to exercise directly
any remedies other than those set forth in the preceding paragraph available to
the holders of the Junior Subordinated Debentures unless there shall have been
an event of default under the Trust Agreement. See "Description of Capital
Securities -- Events of Default; Notice."
 
CONSOLIDATION, MERGER, SALE OF ASSETS AND OTHER TRANSACTION
 
     The Indenture provides that the Corporation may not consolidate with or
merge into any other Person or convey, transfer or lease its properties and
assets substantially as an entirety to any Person, and no person may consolidate
with or merge into the Corporation or convey, transfer or lease its properties
and assets substantially as an entirety to the Corporation, unless (i) if the
Corporation consolidates with or merges into another Person or conveys or
transfers its properties and assets substantially as an entirety to any Person,
the successor Person is organized under the laws of the United States or any
state or the District of Columbia, and such successor Person expressly assumes
the Corporation's obligations on the Junior Subordinated Debentures issued under
the Indenture, provided, however, that nothing in the Indenture shall be deemed
to restrict or prohibit, and no supplemental indenture shall be required in the
case of, the merger of a Principal Subsidiary Bank (as defined below) with and
into a Principal Subsidiary Bank or the Corporation, the consolidation of
Principal Subsidiary Banks into a Principal Subsidiary Bank or the Corporation,
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 the
Corporation, if, in any such case in which the surviving, resulting or acquiring
entity is not the Corporation, the Corporation would own, directly or
indirectly, at least 80% of the voting securities of the Principal Subsidiary
Bank (and of any other Principal Subsidiary Bank any voting securities of which
are owned, directly or indirectly, by such Principal Subsidiary Bank) surviving
such merger, resulting from such consolidation or acquiring such assets; (ii)
immediately after giving effect thereto, no Debenture Event of Default, and no
event which, after notice or lapse of time or both, would become a Debenture
Event of Default, shall have occurred and be continuing; and (iii) certain other
conditions as prescribed by the Indenture are satisfied.
 
     For purposes of clause (i) above, the term "Principal Subsidiary Bank"
means each of (i) PNC Bank, (ii) any other banking subsidiary of the
Corporation, the consolidated assets of which constitute 20% or more of the
consolidated assets of the Corporation and its consolidated subsidiaries, (iii)
any other banking subsidiary designated as a Principal Subsidiary Bank pursuant
to a resolution of the Board of Directors of the Corporation and set forth in an
officers' certificate delivered to the Debenture Trustee, and (iv) any banking
subsidiary of the Corporation that owns, directly or indirectly, any voting
securities, or options, warrants or rights to subscribe for
                                       13
<PAGE>   42
 
or purchase voting securities, of any Principal Subsidiary Bank under clause
(i), (ii) or (iii), and in the case of clause (i), (ii), (iii) or (iv) their
respective successors (whether by consolidation, merger, conversion, transfer of
substantially all their assets and business or otherwise) so long as any such
successor is a banking subsidiary (in the case of clause (i), (ii) or (iii) or a
subsidiary (in the case of clause (iv)) of the Corporation.
 
     The provisions of the Indenture do not afford holders of the Junior
Subordinated Debentures protection in the event of a highly leveraged or other
transaction involving the Corporation that may adversely affect holders of the
Junior Subordinated Debentures.
 
CONVERSION OR EXCHANGE
 
     If and to the extent indicated in the applicable Prospectus Supplement, the
Junior Subordinated Debentures of any series may be convertible or exchangeable
into Junior Subordinated Debentures of another series or into Capital Securities
of another series. The specific terms on which Junior Subordinated Debentures of
any series may be so converted or exchanged will be set forth in the applicable
Prospectus Supplement. Such terms may include provisions for conversion or
exchange, either mandatory, at the option of the holder, or at the option of the
Corporation, in which case the number of shares of Capital Securities or other
securities to be received by the holders of Junior Subordinated Debentures would
be calculated as of a time and in the manner stated in the applicable Prospectus
Supplement.
 
SUBORDINATION
 
     The Junior Subordinated Debentures will be subordinate and junior in right
of payment, to the extent set forth in the Indenture, to all Senior Indebtedness
of the Corporation. If the Corporation defaults in the payment of any principal,
premium, if any, or interest, if any, or any other amount payable on any Senior
Indebtedness when the same becomes due and payable, whether at maturity or at a
date fixed for redemption or by declaration of acceleration or otherwise, then,
unless and until such default has been cured or waived or has ceased to exist or
all Senior Indebtedness has been paid, no direct or indirect payment (in cash,
property, securities, by setoff or otherwise) may be made or agreed to be made
on the Junior Subordinated Debentures, or in respect of any redemption,
repayment, retirement, purchase or other acquisition of any of the Junior
Subordinated Debentures.
 
     As used herein, "Senior Indebtedness" means, whether recourse is to all or
a portion of the assets of the Corporation and whether or not contingent, (i)
every obligation of the Corporation for money borrowed; (ii) every obligation of
the Corporation evidenced by bonds, debentures, notes or other similar
instruments, including obligations incurred in connection with the acquisition
of property, assets or businesses; (iii) every reimbursement obligation of the
Corporation with respect to letters of credit, bankers' acceptances or similar
facilities issued for the account of the Corporation; (iv) every obligation of
the Corporation issued or assumed as the deferred purchase price of property
services (but excluding trade accounts payable or accrued liabilities arising in
the ordinary course of business); (v) every capital lease obligation of the
Corporation; (vi) every obligation of the Corporation for claims (as defined in
Section 101(4) of the United States Bankruptcy Code of 1978, as amended) in
respect of derivative products such as interest and foreign exchange rate
contracts, commodity contracts and similar arrangements; and (vii) every
obligation of the type referred to in clause (i) through (vi) of another person
and all dividends of another person the payment of which, in either case, the
Corporation has guaranteed or is responsible or liable, directly or indirectly,
as obligor or otherwise; without limiting the generality of the foregoing,
Senior Indebtedness shall include (i) the following obligations of PNC Funding
Corp which are guaranteed by the Corporation: (A) 9 7/8% Subordinated Notes Due
2001, (B) 6 7/8% Subordinated Notes Due 2003, (C) 6 1/8% Subordinated Notes Due
2003, (D) 7 3/4% Subordinated Notes Due 2004, (E) 6 7/8% Subordinated Notes Due
2007, (F) 6.50% Subordinated Notes Due 2008, (G) 5.43% Senior Notes Due 2000,
(H) 5.18% Senior Notes Due 1999, (I) 10.55% Equity Commitment Notes Due 1998,
and (J) $500 million credit facility under an Amended and Restated Credit
Agreement dated as of March 18, 1996, (ii) the following joint and several
obligations of the Corporation and PNC Bancorp, Inc. assumed in connection with
the merger of Midlantic Corporation with PNC Bancorp, Inc.: (A) 8 1/4%
Convertible Subordinated Debentures Due 2010, (B) 9.875% Subordinated Capital
Notes Due 1999, (C) 9.20% Subordinated Capital Notes Due 2001 and (D) 9.25%
Senior Notes Due 1999; and (iii) the obligations of the Corporation under the
8 1/4% Convertible Subordinated Debentures Due 2008. "Senior Indebtedness" shall
not include (i) any obligations which, by their terms, are expressly stated to
rank pari passu in right of payment with, or to not be superior in right of
payment
 
                                       14
<PAGE>   43
 
to, the Junior Subordinated Debentures, (ii) any Senior Indebtedness of the
Corporation which when incurred and without respect to any election under
Section 1111(b) of the United States Bankruptcy Code of 1978, as amended, was
without recourse to the Corporation, (iii) any Senior Indebtedness of the
Corporation to any of its subsidiaries, (iv) Senior Indebtedness to any
executive officer or director of the Corporation or (v) any indebtedness in
respect of debt securities issued to any trust, or a trustee of such trust,
partnership or other entity affiliated with the Corporation that is a financing
entity of the Corporation in connection with the issuance of such financing
entity of securities that are similar to the Capital Securities.
 
     In the event of (i) certain events of bankruptcy, dissolution or
liquidation of the Corporation, (ii) any proceeding for the liquidation,
dissolution or other winding up of the Corporation, voluntary or involuntary,
whether or not involving insolvency or bankruptcy proceedings, (iii) any
assignment by the Corporation for the benefit of creditors or (iv) any other
marshalling of the assets of the Corporation, all Senior Indebtedness (including
any interest thereon accruing after the commencement of any such proceedings)
shall first be paid in full before any payment or distribution, whether in cash,
securities or other property, shall be made on account of the Junior
Subordinated Debentures. In such event, any payment or distribution on account
of the Junior Subordinated Debentures, whether in cash, securities or other
property, that would otherwise (but for the subordination provisions) be payable
or deliverable in respect of the Junior Subordinated Debentures will be paid or
delivered directly to the holders of Senior Indebtedness in accordance with the
priorities then existing among such holders until all Senior Indebtedness
(including any interest thereon accruing after the commencement of any such
proceedings) has been paid in full.
 
     In the event of any such proceeding, after payment in full of all sums
owing with respect to Senior Indebtedness, the holders of Junior Subordinated
Debentures, together with the holders of any obligations of the Corporation
ranking on a parity with the Junior Subordinated Debentures, will be entitled to
be paid from the remaining assets of the Corporation the amounts at the time due
and owing on the Junior Subordinated Debentures and such other obligations
before any payment or other distribution, whether in cash, property or
otherwise, will be made on account of any capital stock or obligations of the
Corporation ranking junior to the Junior Subordinated Debentures and such other
obligations. If any payment or distribution on account of the Junior
Subordinated Debentures of any character or any security, whether in cash,
securities or other property is received by any holder of any Junior
Subordinated Debentures in contravention of any of the terms hereof and before
all the Senior Indebtedness has been paid in full, such payment or distribution
or security will be received in trust for the benefit of, and must be paid over
or delivered and transferred to, the holders of the Senior Indebtedness at the
time outstanding in accordance with the priorities then existing among such
holders for application to the payment of all Senior Indebtedness remaining
unpaid to the extent necessary to pay all such Senior Indebtedness in full. By
reason of such subordination, in the event of the insolvency of the Corporation,
holders of Senior Indebtedness may receive more, ratably, and holders of the
Junior Subordinated Debentures may receive less, ratably, than the other
creditors of the Corporation. Such subordination will not prevent the occurrence
of any Debenture Event of Default in respect of the Junior Subordinated
Debentures.
 
     The Indenture places no limitation on the amount of Senior Indebtedness
that may be incurred by the Corporation. The Corporation expects from time to
time to incur additional indebtedness and other obligations constituting Senior
Indebtedness.
 
TRUST EXPENSES
 
     Pursuant to the Indenture, the Corporation, as borrower, has agreed to pay
all debts and other obligations (other than with respect to the Capital
Securities) and all costs and expenses of each Issuer Trust (including costs and
expenses relating to the organization of each Issuer Trust, the fees and
expenses of the Issuer Trustees and the cost and expenses relating to the
operation of each Issuer Trust) and to pay any and all taxes and all costs and
expenses with respect thereto (other than United States withholding taxes) to
which each Issuer Trust might become subject.
 
SATISFACTION AND DISCHARGE
 
     The Indenture provides that when, among other things, all Junior
Subordinated Debentures of a series not previously delivered to the Debenture
Trustee for cancellation (i) have become due and payable or (ii) will become due
and payable at their Stated Maturity within one year, and the Corporation
deposits or causes to be
                                       15
<PAGE>   44
 
deposited with the Debenture Trustee funds, in trust, for the purpose of, and in
an amount sufficient for, payment and discharge of the entire indebtedness on
the Junior Subordinated Debentures of such series not previously delivered to
the Debenture Trustee for cancellation, for the principal and premium, if any,
and interest to the date of the deposit or to the Stated Maturity, as the case
may be, then the Indenture will cease to be of further effect with respect to
that series (except as to the Corporation's obligations to pay all other sums
due with respect to that series pursuant to the Indenture and or provide the
officer's certificates and opinions of counsel described therein), and the
Corporation will be deemed to have satisfied and discharged the Indenture with
respect to that series.
 
THE DEBENTURE TRUSTEE
 
     The Debenture Trustee, other than during the occurrence and continuance of
a default by the Corporation in performance of its obligations under the Junior
Subordinated Debentures, is under no obligation to exercise any of the powers
vested in it by the Indenture at the request of any holder of Junior
Subordinated Debentures, unless offered reasonable indemnity by such holder
against the costs, expenses and liabilities that might be incurred thereby. The
Debenture Trustee is not required to expend or risk its own funds or otherwise
incur personal financial liability in the performance of its duties if the
Debenture Trustee reasonably believes that repayments or adequate indemnity is
not reasonably assured to it.
 
     Bankers Trust Company, the Debenture Trustee, may serve from time to time
as trustee under other indentures or trust agreements with the Corporation or
its subsidiaries relating to other issues of their securities. In addition, the
Corporation and certain of its affiliates may have other banking relationships
with Bankers Trust Company and its affiliates.
 
GOVERNING LAW
 
     The Indenture and the Junior Subordinated Debentures will be governed by,
and construed in accordance with, the laws of the State of New York.
 
CORRESPONDING JUNIOR SUBORDINATED DEBENTURES
 
     The Corresponding Junior Subordinated Debentures may be issued in one or
more series of Junior Subordinated Debentures under the Indenture with terms
corresponding to the terms of a series of Related Capital Securities. In that
event, concurrently with the issuance of each Issuer Trust's Capital Securities,
such Issuer Trust will invest the proceeds thereof and the consideration paid by
the Corporation for the Common Securities of such Issuer Trust in such series of
Corresponding Junior Subordinated Debentures issued by the Corporation to such
Issuer Trust. Each series of Corresponding Junior Subordinated Debentures will
be in the principal amount equal to the aggregate stated Liquidation Amount of
the Related Capital Securities and the Common Securities of such Issuer Trust
and will rank pari passu with all other series of Junior Subordinated
Debentures. Holders of the Related Capital Securities for a series of
Corresponding Junior Subordinated Debentures will have the rights, in connection
with modifications to the Indenture or upon occurrence of Debenture Events of
Default, as described under "-- Modification of Indenture," "-- Debenture Events
of Default" and "-- Enforcement of Certain Rights by Holders of Capital
Securities," unless provided otherwise in the Prospectus Supplement for such
Related Capital Securities.
 
     Unless otherwise specified in the applicable Prospectus Supplement, if a
Tax Event, Capital Trust Event or Investment Company Event shall occur and be
continuing, the Corporation may, at its option and subject to prior approval of
the Federal Reserve if then so required under applicable capital guidelines or
policies, redeem the Corresponding Junior Subordinated Debentures at any time
within 90 days of the occurrence of such Tax Event, Capital Treatment Event or
Investment Company Event, in whole but not in part, subject to the provisions of
the Indenture and whether or not such Corresponding Junior Subordinated
Debentures are then otherwise redeemable at the option of the Corporation. The
redemption price for any Corresponding Junior Subordinated Debentures shall be
equal to 100% of the principal amount of such Corresponding Junior Subordinated
Debentures then outstanding plus accrued and unpaid interest to the date fixed
for redemption plus any redemption premium required to be paid thereon. For so
long as the applicable Issuer Trust is the holder of all the oustanding
Corresponding Junior Subordinated Debentures of such series, the proceeds of any
such redemption will be used by the Issuer Trust to redeem the corresponding
Trust Securities in accordance with their terms. The Corporation
 
                                       16
<PAGE>   45
 
may not redeem a series of Corresponding Junior Subordinated Debentures in part
unless all accrued and unpaid interest has been paid in full on all outstanding
Corresponding Junior Subordinated Debentures of such series for all interest
periods terminating on or prior to the Redemption Date.
 
     The Corporation will convenant, as to each series of Corresponding Junior
Subordinated Debentures, (i) to maintain directly or indirectly 100% ownership
of the Common Securities of the Issuer Trust to which such Corresponding Junior
Subordinated Debentures have been issued, provided that certain successors which
are permitted pursuant to the Indenture may succeed to the Corporation's
ownership of the Common Securities, (ii) not to voluntarily terminate, wind up
or liquidate any Issuer Trust, except (a) in connection with a distribution of
Corresponding Junior Subordinated Debentures to the holders of the Capital
Securities in exchange therefor upon liquidation of such Issuer Trust, or (b) in
connection with certain mergers, consolidations or amalgamations permitted by
the related Trust Agreement, in either such case, if so specified in the
applicable Prospectus Supplement upon prior approval of the Federal Reserve if
then so required under applicable capital guidelines or policies, and (iii) to
use its reasonable efforts, consistent with the terms and provisions of the
related Trust Agreement, to cause such Issuer Trust to remain classified as a
grantor trust and not as an association taxable as a corporation for United
States federal income tax purposes.
 
                       DESCRIPTION OF CAPITAL SECURITIES
 
     Pursuant to the terms of the Trust Agreement for each Issuer Trust, the
Issuer Trustees on behalf of such Issuer Trust will issue the Capital Securities
and the Common Securities. The Capital Securities of a particular Issuer Trust
will represent preferred beneficial ownership interests in the assets of the
Issuer Trust and the holders thereof will be entitled to a preference in certain
circumstances with respect to the Distributions and amounts payable on
redemption or liquidation over the Common Securities of such Issuer Trust, as
well as other benefits as described in the corresponding Trust Agreement. This
summary of certain provisions of the Capital Securities and each Trust Agreement
does not purport to be complete and is subject to, and is qualified in its
entirety by reference to, all the provisions of each Trust Agreement, including
the definitions therein of certain terms, and the Trust Indenture Act, to each
of which reference is hereby made. Wherever particular defined terms of a Trust
Agreement (as amended or supplemented from time to time) are referred to herein
or in a Prospectus Supplement, such defined terms are incorporated herein or
therein by reference. The form of the Trust Agreement has been filed as an
exhibit to the Registration Statement of which this Prospectus forms a part.
Each of the Issuer Trusts is a legally separate entity and the assets of one are
not available to satisfy the obligations of any of the others or of any other
statutory business trust whose common securities are owned by the Corporation.
 
GENERAL
 
     The Capital Securities of an Issuer Trust will rank pari passu, and
payments will be made thereon pro rata, with the Common Securities of the Issuer
Trust except as described under "-- Subordination of Common Securities." The
Corresponding Junior Subordinated Debentures will be registered in the name of
the related Issuer Trust and held by the Property Trustee in trust for the
benefit of the holders of the Related Capital Securities and Common Securities.
Each Guarantee Agreement (the "Guarantee") will be a guarantee on a subordinated
basis with respect to the related Capital Securities but will not guarantee
payment of Distributions or amounts payable on redemption or liquidation of such
Capital Securities when the related Issuer Trust does not have funds on hand
available to make such payments. See "Description of Guarantees."
 
DISTRIBUTIONS
 
     The Capital Securities will represent preferred undivided beneficial
interests in the assets of the relevant Issuer Trust and Distributions on the
Capital Securities will be cumulative, will accumulate from the date of original
issuance and will be payable on such dates as specified in the applicable
Prospectus Supplement. The Distributions on each Capital Security will be
payable at a rate specified in the applicable Prospectus Supplement for such
Capital Securities. The amount of Distributions payable for any period will be
computed on the basis of a 360-day year of twelve 30-day months unless otherwise
specified in the applicable Prospectus Supplement. Distributions to which
holders of Capital Securities are entitled will accumulate additional
Distributions at the rate per annum if and as specified in the applicable
Prospectus Supplement. The term "Distributions" as used herein includes any such
additional Distributions unless otherwise stated.
 
                                       17
<PAGE>   46
 
     In the event that any date on which Distributions are payable on the
Capital Securities is not a Business Day (as defined below), then payment of the
Distributions payable on such date will be made on the next succeeding day that
is a Business Day (and without any additional Distributions or other payment in
respect of any such delay) except that, if such Business Day is in the next
succeeding calendar year, payment of such Distribution shall be made on the
immediately preceding Business Day, in either case with the same force and
effect as if made on such date (each date on which Distributions are payable in
accordance with the foregoing, a "Distribution Date"). A "Business Day" shall
mean any day other than (a) a Saturday or a Sunday, (b) a day on which banking
institutions in Pittsburgh, Pennsylvania or The City of New York are authorized
or required by law or executive order to remain closed or (c) a day on which the
corporate trust office of the Property Trustee or the Debenture Trustee is
closed for business.
 
     If provided in the applicable Prospectus Supplement, so long as no
Debenture Event of Default has occurred and is continuing the Corporation will
have the right under the Indenture, pursuant to which it will issue the
Corresponding Junior Subordinated Debentures, to defer the payment of interest
at any time or from time to time on any series of the Corresponding Junior
Subordinated Debentures for up to such number of consecutive interest payment
periods which will be specified in such Prospectus Supplement relating to such
series (each, an "Extension Period"), provided, that no Extension Period may
extend beyond the Stated Maturity of the Corresponding Junior Subordinated
Debentures. As a consequence of any such deferral, Distributions on the Related
Capital Securities would be deferred (but would continue to accumulate
additional Distributions thereon at the rate per annum set forth in the
Prospectus Supplement for such Capital Securities) by the Issuer Trust of such
Capital Securities during any such Extension Period. During such Extension
Period, the Corporation may not (i) declare or pay any dividends or
distributions on, or redeem, purchase, acquire or make a liquidation payment
with respect to, any of the Corporation's capital stock or (ii) make any payment
of principal, interest or premium, if any, on or repay, repurchase or redeem any
debt securities of the Corporation that rank pari passu in all respects with or
junior in interest to the Corresponding Junior Subordinated Debentures (other
than (a) repurchases, redemptions or other acquisitions of shares of capital
stock of the Corporation in connection with any employment contract, benefit
plan or other similar arrangement with or for the benefit of any one or more
employees, officers, directors or consultants, in connection with a dividend
reinvestment or stockholder stock purchase plan or in connection with the
issuance of capital stock of the Corporation (or securities convertible into or
exercisable for such capital stock) as consideration in an acquisition
transaction entered into prior to the applicable Extension Period, (b) as a
result of an exchange or conversion of any class or series of the Corporation's
capital stock (or any capital stock of a subsidiary of the Corporation) for any
class or series of the Corporation's capital stock or of any class or series of
the Corporation's indebtedness for any class or series of the Corporation's
capital stock, (c) the purchase of fractional interests in shares of the
Corporation's capital stock pursuant to the conversion or exchange provisions of
such capital stock or the security being converted or exchanged, (d) any
declaration of a dividend in connection with any stockholder's rights plan, or
the issuance of rights, stock or other property under any stockholder's rights
plans, or the redemption or repurchase of rights pursuant thereto, or (e) any
dividend in the form of stock, warrants, options or other rights where the
dividend stock issuable upon exercise of such warrants, options or other rights
is the same stock as that on which the dividend is being paid or ranks pari
passu with or junior to such stock).
 
     The revenue of each Issuer Trust available for distribution to holders of
its Capital Securities will be limited to payments under the Corresponding
Junior Subordinated Debentures in which the Issuer Trust will invest the
proceeds from the issuance and sale of its Trust Securities. See "Description of
Junior Subordinated Debentures -- Corresponding Junior Subordinated Debentures."
If the Corporation does not make interest payments on such Corresponding Junior
Subordinated Debentures, the Issuer Trust may not have funds available to pay
Distributions on the Related Capital Securities. The payment of Distributions
and other amounts payable on the Capital Securities (if and to the extent the
Issuer Trust has funds legally available for the payment of such Distributions
and cash sufficient to make such payments) is guaranteed by the Corporation on
the basis set forth herein under "Description of Guarantees."
 
     Distributions on the Capital Securities will be payable to the holders
thereof as they appear on the register of such Issuer Trust on the relevant
record dates, as specified in the applicable Prospectus Supplement.

REDEMPTION OR EXCHANGE
 
     Upon the repayment or redemption, in whole or in part, of any Corresponding
Junior Subordinated Debentures, whether at maturity or upon earlier redemption
as provided in the Indenture, the proceeds from such repayment or redemption
shall be applied by the Property Trustee to redeem a Like Amount (as defined
below) of the Trust Securities, upon not less than 30 nor more than 60 days'
notice, at a redemption price (the "Redemption Price") equal to the aggregate
Liquidation Amount of such Trust Securities plus accumulated but unpaid
Distributions thereon to the date of redemption (the "Redemption Date") and the
related amount of the premium, if any, paid by the Corporation upon the
concurrent redemption of such Corresponding Junior Subordinated Debentures. See
"Description of Junior Subordinated Debentures -- Redemption." If less than all
of any series of Corresponding Junior Subordinated Debentures are to be repaid
or redeemed on a Redemption Date, then the proceeds from such repayment or
redemption shall be allocated to the redemption pro rata of the Related Capital
Securities and the Common Securities. The amount of premium, if any, paid by the
Corporation upon the redemption of all or any part of any series of any
Corresponding Junior Subordinated Debentures to be repaid or redeemed on a
Redemption Date shall be allocated to the redemption pro rata of the Related
Capital Securities and the Common Securities.
 
     The Corporation will have the right to redeem any series of Corresponding
Junior Subordinated Debentures (i) on or after such date as may be specified in
the applicable Prospectus Supplement, in whole at any time or in part from time
to time, or (ii) in whole (but not in part), at any time within 90 days
following the occurrence and during the continuation of a Tax Event, Investment
Company Event or Capital Treatment Event, in each case subject to receipt of
prior approval by the Federal Reserve if then required under applicable capital
guidelines or policies.
 
     Subject to the Corporation's having received prior approval of the Federal
Reserve to do so if then required under applicable capital guidelines or
policies, the Corporation has the right at any time to terminate any Issuer
Trust and, after satisfaction of the liabilities of creditors of such Issuer
Trust as provided by applicable law, cause such Corresponding Junior
Subordinated Debentures in respect of the Related Capital Securities and Common
Securities issued by such Issuer Trust to be distributed to the holders of such
Related Capital Securities and Common Securities in exchange therefor upon
liquidation of such Issuer Trust.
 
     After the liquidation date fixed for any distribution of Corresponding
Junior Subordinated Debentures for any series of Capital Securities (i) such
series of Capital Securities will no longer be deemed to be outstanding, (ii)
the depositary or its nominee, as the registered holder of such series of
Capital Securities, will receive a registered global certificate or certificates
representing the Corresponding Junior Subordinated Debentures to be delivered
upon such distribution and (iii) any certificates representing such series of
Capital Securities not held by The Depository Trust Company ("DTC") or its
nominee will be deemed to represent the Corresponding Junior Subordinated
Debentures having a principal amount equal to the stated Liquidation Amount of
such series of Capital Securities, and bearing accrued and unpaid interest in an
amount equal to the accrued and unpaid Distributions on such series of Capital
Securities until such certificates are presented to the securities registrar for
transfer or reissuance.
 
     There can be no assurance as to the market prices for the Capital
Securities or the Corresponding Junior Subordinated Debentures that may be
distributed in exchange for Capital Securities if a dissolution and liquidation
of an Issuer Trust were to occur. Accordingly, the Capital Securities that an
investor may purchase, or the Corresponding Junior Subordinated Debentures that
the investor may receive on dissolution and liquidation of an Issuer Trust, may
trade at a discount to the price that the investor paid to purchase the Capital
Securities offered hereby.
 
     "Like Amount" means (i) with respect to a redemption of any series of Trust
Securities, Trust Securities of such series having a Liquidation Amount (as
defined below) equal to that portion of the principal amount of Corresponding
Junior Subordinated Debentures to be contemporaneously redeemed in accordance
with the Indenture, allocated to the Common Securities and to the Related
Capital Securities based upon the relative Liquidation Amounts of such classes,
and (ii) with respect to a distribution of Corresponding Junior Subordinated
Debentures to holders of any series of Trust Securities in exchange therefor in
connection with a dissolution or liquidation of the related Issuer Trust,
Corresponding Junior Subordinated Debentures having a principal amount
 
                                       19
<PAGE>   48
 
equal to the Liquidation Amount of the Trust Securities of the holder to whom
such Corresponding Junior Subordinated Debentures would be distributed.
 
     "Liquidation Amount" means the stated amount per Trust Security as set
forth in the applicable Prospectus Supplement.
 
REDEMPTION PROCEDURES
 
     Capital Securities redeemed on each Redemption Date shall be redeemed at
the Redemption Price with the applicable proceeds from the contemporaneous
redemption of the Corresponding Junior Subordinated Debentures. Redemptions of
the Capital Securities shall be made and the Redemption Price shall be payable
on each Redemption Date only to the extent that the related Issuer Trust has
funds on hand available for the payment of such Redemption Price. See also
"-- Subordination of Common Securities."
 
     If an Issuer Trust gives a notice of redemption in respect of its Capital
Securities, then, by 12:00 noon, New York City time, on the Redemption Date, to
the extent funds are available, in the case of Capital Securities held in book
entry form, the Property Trustee will deposit irrevocably with DTC funds
sufficient to pay the applicable Redemption Price and will give DTC irrevocable
instructions and authority to pay the Redemption Price to the holders of such
Capital Securities. See "Book-Entry Issuance." If such Capital Securities are no
longer in book-entry form, the Property Trustee, to the extent funds are
available, will irrevocably deposit with the paying agent for such Capital
Securities funds sufficient to pay the Redemption Price and will give such
paying agent irrevocable instructions and authority to pay the Redemption Price
to the holders thereof upon surrender of their certificates evidencing such
Capital Securities. Notwithstanding the foregoing, Distributions payable on or
prior to the Redemption Date for any Capital Securities called for redemption
shall be payable to the holders of such Capital Securities on the relevant
record dates for the related Distribution Dates. If notice of redemption shall
have been given and funds deposited as required, then upon the date of such
deposit, all rights of the holders of such Capital Securities so called for
redemption will cease, except the right of the holders of such Capital
Securities to receive the Redemption Price and any distribution payable in
respect of the Capital Securities on or prior to the Redemption Date, but
without interest on such Redemption Price, and such Capital Securities will
cease to be outstanding. In the event that any date fixed for redemption of
Capital Securities is not a Business Day, then payment of the Redemption Price
payable on such date will be made on the next succeeding day which is a Business
Day (and without any interest or other payment in respect of any such delay),
except that, if such Business Day falls in the next calendar year, such payment
will be made on the immediately preceding Business Day. In the event that
payment of the Redemption Price in respect of Capital Securities called for
redemption is improperly withheld or refused and not paid either by the Issuer
Trust or by the Corporation pursuant to the relevant Guarantee as described
under "Description of Guarantees," Distributions on such Capital Securities will
continue to accrue at the then applicable rate, from the Redemption Date
originally established by the Issuer Trust for such Capital Securities to the
date such Redemption Price is actually paid, in which case the actual payment
date will be the date fixed for redemption for purposes of calculating the
Redemption Price.
 
     Subject to applicable law (including, without limitation, United States
federal securities law), the Corporation or its affiliates may at any time and
from time to time purchase outstanding Capital Securities by tender, in the open
market or by private agreement and may resell such securities.
 
     Payment of the Redemption Price on the Capital Securities and any
distribution of Corresponding Junior Subordinated Debentures to holders of
Capital Securities shall be made to the applicable record holders thereof as
they appear on the register for such Capital Securities on the relevant record
date, as specified in the applicable Prospectus Supplement.
 
     If less than all of the Capital Securities and Common Securities issued by
an Issuer Trust are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of such Capital Securities and Common Securities to be
redeemed shall be allocated pro rata to the Capital Securities and the Common
Securities based upon the relative Liquidation Amounts of such classes. The
particular Capital Securities to be redeemed shall be selected on a pro rata
basis not more than 60 days prior to the Redemption Date by the Property Trustee
from the outstanding Capital Securities not previously called for redemption or
if the Capital Securities are then held in the form of a Global Capital
Security, in accordance with DTC's customary procedures. The Property Trustee
shall promptly notify the securities registrar in writing of the Capital
Securities selected for redemption and, in the case
 
                                       20
<PAGE>   49
 
of any Capital Securities selected for partial redemption, the Liquidation
Amount thereof to be redeemed. For all purposes of each Trust Agreement, unless
the context otherwise requires, all provisions relating to the redemption of
Capital Securities shall relate, in the case of any Capital Securities redeemed
or to be redeemed only in part, to the portion of the aggregate Liquidation
Amount of Capital Securities which has been or is to be redeemed.
 
     Notice of any redemption will be mailed at least 30 days but not more than
60 days before the Redemption Date to each holder of Capital Securities to be
redeemed at its registered address. Unless the Corporation defaults in payment
of the Redemption Price on the Junior Subordinated Debentures, on and after the
Redemption Date interest will cease to accrue on the Junior Subordinated
Debentures or portions thereof (and, unless payment of the Redemption Price in
respect of the Capital Securities is withheld or refused and not paid either by
the Issuer Trust or the Corporation pursuant to the Guarantee, Distributions
will cease to accumulate on the Capital Securities or portions thereof) called
for redemption.
 
SUBORDINATION OF COMMON SECURITIES
 
     Payment of Distributions on, and the Redemption Price of, and the
Liquidation Distribution (as defined below) in respect of, each Issuer Trust's
Capital Securities and Common Securities, as applicable, shall be made pro rata
based on the Liquidation Amount of such Capital Securities and Common
Securities; provided, however, that if on any Distribution Date or Redemption
Date a Debenture Event of Default shall have occurred and be continuing as a
result of any failure by the Corporation to pay amounts in respect of the Junior
Subordinated Debentures when due, no payment of any Distribution on, or
Redemption Price of or the Liquidated Distribution in respect of, any of the
Issuer Trust's Common Securities, and no other payment on account of the
redemption, liquidation or other acquisition of such Common Securities, shall be
made unless payment in full in cash of all accumulated and unpaid Distributions
on all of the Issuer Trust's outstanding Capital Securities for all Distribution
periods terminating on or prior thereto, or in the case of payments of the
Redemption Price the full amount of such Redemption Price on all of the Issuer
Trust's outstanding Capital Securities then called for redemption, shall have
been made or provided for, and all funds available to the Property Trustee shall
first be applied to the payment in full in cash of all Distributions on, or
Redemption Price of, the Issuer Trust's Capital Securities then due and payable.
 
     In the case of any Event of Default (as defined below) under the applicable
Trust Agreement resulting from a Debenture Event of Default, the Corporation as
holder of such Issuer Trust's Common Securities will be deemed to have waived
any right to act with respect to any such Event of Default under the applicable
Trust Agreement until the effects of all such Events of Default with respect to
such Capital Securities have been cured, waived or otherwise eliminated. See
"-- Events of Default; Notice" and "Description of Junior Subordinated
Debentures -- Debenture Events of Default." Until all events of default under
the applicable Trust Agreement with respect to the Capital Securities have been
so cured, waived or otherwise eliminated, the Property Trustee shall act solely
on behalf of the holders of such Capital Securities and not on behalf of the
Corporation as holder of the Issuer Trust's Common Securities, and only the
holders of such Capital Securities will have the right to direct the Property
Trustee to act on their behalf.
 
LIQUIDATION DISTRIBUTION UPON DISSOLUTION
 
     Pursuant to each Trust Agreement, each Issuer Trust will automatically
dissolve upon expiration of its term or, if earlier, will dissolve on the first
to occur of: (i) certain events of bankruptcy, dissolution or liquidation of the
Corporation; (ii) the distribution of a Like Amount of the Corresponding Junior
Subordinated Debentures to the holders of its Trust Securities, if the
Corporation, as Depositor, has given written direction to the Property Trustee
to dissolve such Issuer Trust (subject to the Corporation having received prior
approval of the Federal Reserve if so required under applicable capital
guidelines or policies); (iii) the repayment of all of the Issuer Trust's
Capital Securities in connection with the redemption of all its Trust Securities
as described under "-- Redemption or Exchange;" and (iv) the entry of an order
for the dissolution of the Issuer Trust by a court of competent jurisdiction.
 
     If an early dissolution occurs as described in clause (i), (ii) or (iv)
above, the Issuer Trust will be liquidated by the Property Trustee as
expeditiously as the Property Trustee determines to be possible by distributing,
after satisfaction of liabilities to creditors of such Issuer Trust as provided
by applicable law, to the holders of such Trust Securities in exchange therefor
a Like Amount of the Corresponding Junior Subordinated Debentures,
                                       21
<PAGE>   50
 
unless such distribution is not practical, in which event such holders will be
entitled to receive out of the assets of the Issuer Trust available for
distribution to holders, after satisfaction of liabilities to creditors of such
Issuer Trust as provided by applicable law, an amount equal to, in the case of
holders of Capital Securities, the aggregate Liquidation Amount plus accrued and
unpaid Distributions thereon to the date of payment (such amount being the
"Liquidation Distribution"). If such Liquidation Distribution can be paid only
in part because such Issuer Trust has insufficient assets available to pay in
full the aggregate Liquidation Distribution, then the amounts payable directly
by such Issuer Trust on its Capital Securities shall be paid on a pro rata
basis. The holder(s) of such Issuer Trust's Common Securities will be entitled
to receive distributions upon any such liquidation pro rata with the holders of
its Capital Securities, except that if a Debenture Event of Default has occurred
and is continuing as a result of any failure by the Corporation to pay any
amounts in respect of the Junior Subordinated Debentures when due, the Capital
Securities shall have a priority over the Common Securities. See
"-- Subordination of Common Securities."
 
EVENTS OF DEFAULT; NOTICE
 
     Any one of the following events constitutes an "Event of Default" under
each Trust Agreement (an "Event of Default") with respect to the Capital
Securities issued under such Trust Agreement (whatever the reason for such Event
of Default and whether it is voluntary or involuntary or be effected by
operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body):
 
     (i)  the occurrence of a Debenture Event of Default under the Indenture
(see "Description of Junior Subordinated Debentures -- Debenture Events of
Default"); or
 
     (ii) default by the Issuer Trust in the payment of any Distribution when it
becomes due and payable and continuation of such default for a period of 30
days; or
 
     (iii) default by the Issuer Trust in the payment of any Redemption Price of
any Trust Security when it becomes due and payable; or
 
     (iv) default in the performance, or breach, in any material respect, of any
covenant or warranty of the Issuer Trustees in such Trust Agreement (other than
a covenant or warranty a default in the performance of which or the breach of
which is dealt with in clause (ii) or (iii) above), and continuation of such
default or breach for a period of 60 days after there has been given, by
registered or certified mail, to the Issuer Trustees and the Corporation by the
holders of at least 25% in aggregate Liquidation Amount of the outstanding
Capital Securities of the applicable Issuer Trust, a written notice specifying
such default or breach and requiring it to be remedied and stating that such
notice is a "Notice of Default" under such Trust Agreement; or
 
     (v)  the occurrence of certain events of bankruptcy or insolvency with
respect to the Property Trustee or all or substantially all of its property if a
successor Property Trustee has not been appointed within a period of 90 days
thereof.
 
     Within five Business Days after the occurrence of any Event of Default
actually known to the Property Trustee, the Property Trustee will transmit
notice of such Event of Default to the holders of such Issuer Trust's Trust
Securities and the Administrators, unless such Event of Default shall have been
cured or waived. The Corporation, as Depositor, and the Administrators are
required to file annually with the Property Trustee a certificate as to whether
or not they are in compliance with all the conditions and covenants applicable
to them under each Trust Agreement.
 
     If a Debenture Event of Default has occurred and is continuing, the Capital
Securities shall have a preference over the Common Securities as described
above. See "-- Subordination of Common Securities" and "-- Liquidation
Distribution Upon termination." The existence of an Event of Default does not
entitle the holders of Capital Securities to accelerate the maturity thereof.
 
REMOVAL OF ISSUER TRUSTEES
 
     The holders of at least a majority in aggregate Liquidation Amount of the
outstanding Capital Securities may remove an Issuer Trustee for cause or, if a
Debenture Event of Default has occurred and is continuing, with or without
cause. If an Issuer Trustee is removed by the holders of the outstanding Capital
Securities, the successor
 
                                       22
<PAGE>   51
 
may be appointed by the holders of at least 25% in aggregate Liquidation Amount
of Capital Securities. If an Issuer Trustee resigns, such Issuer Trustee will
appoint its successor. If an Issuer Trustee fails to appoint a successor, the
holders of at least 25% in aggregate Liquidation Amount of the outstanding
Capital Securities may appoint a successor. If a successor has not been
appointed by the holders, any holder of Capital Securities or Common Securities
or the other Issuer Trustee may petition a court in the State of Delaware to
appoint a successor. Any Delaware Trustee must meet the applicable requirements
of Delaware law. Any Property Trustee must be a national or state-chartered
bank, and at the time of appointment have securities rated in one of the three
highest rating categories by a nationally recognized statistical rating
organization and have capital and surplus of at least $50,000,000. No
resignation or removal of an Issuer Trustee and no appointment of a successor
trustee shall be effective until the acceptance of appointment by the successor
trustee in accordance with the provisions of the Trust Agreement.
 
MERGER OR CONSOLIDATION OF ISSUER TRUSTEES
 
     Any Person into which the Property Trustee or the Delaware Trustee may be
merged or converted or with which it may be consolidated, or any Person
resulting from any merger, conversion or consolidation to which such Issuer
Trustee is a party, or any Person succeeding to all or substantially all the
corporate trust business of such Issuer Trustee, shall be the successor of such
Issuer Trustee under each Trust Agreement, provided such Person shall be
otherwise qualified and eligible.
 
MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF THE ISSUER TRUSTS
 
     An Issuer Trust may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other Person, except as
described below or as otherwise described in the Trust Agreement. An Issuer
Trust may, at the request of the holders of the Common Securities, with the
consent of the holders of at least a majority in aggregate Liquidation Amount of
the outstanding Capital Securities, merge with or into, consolidate, amalgamate,
or be replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to, a trust organized as such under the laws of any
State; provided, that (i) such successor entity either (a) expressly assumes all
of the obligations of such Issuer Trust with respect to the Capital Securities
or (b) substitutes for the Capital Securities other securities having
substantially the same terms as the Capital Securities (the "Successor
Securities") so long as the Successor Securities have the same priority as the
Capital Securities with respect to distributions and payments upon liquidation,
redemption and otherwise, (ii) a trustee of such successor entity possessing the
same powers and duties as the Property Trustee is appointed as the holder of the
Corresponding Junior Subordinated Debentures, (iii) such merger, consolidation,
amalgamation, replacement, conveyance, transfer or lease does not cause the
Capital Securities (including any Successor Securities) to be downgraded by any
nationally recognized statistical rating organization, (iv) such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease does not
adversely affect the rights, preferences and privileges of the holders of the
Capital Securities (including any Successor Securities) in any material respect,
(v) such successor entity has a purpose substantially identical to that of the
Issuer Trust, (vi) prior to such merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease, the Corporation has received an
opinion from independent counsel to the Issuer Trust experienced in such matters
to the effect that (a) such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease does not adversely affect the rights, preferences
and privileges of the holders of the Capital Securities (including any Successor
Securities) in any material respect, and (b) following such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease, neither
the Issuer Trust nor such successor entity will be required to register as an
investment company under the Investment Company Act, and (vii) the Corporation
or any permitted successor or assignee owns all of the Common Securities of such
successor entity and guarantees the obligations of such successor entity under
the Successor Securities at least to the extent provided by the Guarantee.
Notwithstanding the foregoing, an Issuer Trust may not, except with the consent
of holders of 100% in aggregate Liquidation Amount of the Capital Securities,
consolidate, amalgamate, merge with or into, or be replaced by or convey,
transfer or lease its properties and assets substantially as an entirety to any
other entity or permit any other entity to consolidate, amalgamate, merge with
or into, or replace it if such consolidation, amalgamation, merger, replacement,
conveyance, transfer or lease would cause the Issuer Trust or the successor
entity to be classified as other than a grantor trust for United States federal
income tax purposes.

VOTING RIGHTS; AMENDMENT OF EACH TRUST AGREEMENT
 
     Except as provided below and under "-- Removal of Issuer Trustees;
Appointment of Successors" and "Description of Guarantees -- Amendments and
Assignment" and as otherwise required by law and the applicable Trust Agreement,
the holders of the Capital Securities will have no voting rights.
 
     Each Trust Agreement may be amended from time to time by the holders of a
majority in Liquidation Amount of the Common Securities and the Property
Trustee, without the consent of the holders of the Capital Securities (i) to
cure any ambiguity, correct or supplement any provisions in such Trust Agreement
that may be inconsistent with any other provision, or to make any other
provisions with respect to matters or questions arising under such Trust
Agreement, provided that any such amendment does not adversely affect in any
material respect the interests of any holder of Trust Securities or (ii) to
modify, eliminate or add to any provisions of such Trust Agreement to such
extent as shall be necessary to ensure that the Issuer Trust will be classified
for United States federal income tax purposes as a grantor trust at any time
that any Trust Securities are outstanding or to ensure that the Issuer Trust
will not be required to register as an "investment company" under the Investment
Company Act; and any such amendments of such Trust Agreement shall become
effective when notice thereof is given to the holders of Trust Securities. Each
Trust Agreement may be amended by the holders of a majority in Liquidation
Amount of the Common Securities and the Property Trustee with (i) the consent of
holders representing not less than a majority (based upon Liquidation Amounts)
of the outstanding Capital Securities, and (ii) receipt by the Issuer Trustees
of an opinion of counsel to the effect that such amendment or the exercise of
any power granted to the Issuer Trustees in accordance with such amendment will
not affect the Issuer Trust's status as a grantor trust for United States
federal income tax purposes or the Issuer Trust's exemption from status as an
"investment company" under the Investment Company Act, provided that without the
consent of each holder of Trust Securities, such Trust Agreement may not be
amended to (i) change the amount or timing of any Distribution on the Trust
Securities or otherwise adversely affect the amount of any Distribution required
to be made in respect of the Trust Securities as of a specified date or (ii)
restrict the right of a holder of Trust Securities to institute suit for the
enforcement of any such payment on or after such date.
 
     So long as any Corresponding Junior Subordinated Debentures are held by the
Issuer Trust, the Property Trustee will not (i) direct the time, method and
place of conducting any proceeding for any remedy available to the Debenture
Trustee, or executing any trust or power conferred on the Property Trustee with
respect to such Corresponding Junior Subordinated Debentures, (ii) waive any
past default that is waivable under the Indenture, (iii) exercise any right to
rescind or annual a declaration that the principal of all the corresponding
Junior Subordinated Debentures shall be due and payable or (iv) consent to any
amendment, modification or termination of the Indenture or such Corresponding
Junior Subordinated Debentures, where such consent shall be required, without,
in each case, obtaining the prior approval of the holders of a majority in
aggregate Liquidation Amount of all outstanding Capital Securities; provided,
however, that where a consent under the Indenture would require the consent of
each holder of Corresponding Junior Subordinated Debentures affected thereby, no
such consent shall be given by the Property Trustee without the prior consent of
each holder of the Related Capital Securities. The Property Trustees may not
revoke any action previously authorized of approved by a vote of the holders of
the Capital Securities except by subsequent vote of the holders of the Capital
Securities. The Property Trustee will notify each holder of Capital Securities
of any notice of default with respect to the Corresponding Junior Subordinated
Debentures. In addition to obtaining the foregoing approvals of the holders of
the Capital Securities, prior to taking any of the foregoing actions, the
Property Trustee shall obtain an opinion of counsel experienced in such matters
to the effect that such action would not cause the Issuer Trust to be classified
as a corporation for United States federal income tax purposes.
 
     Any required approval of holders of Capital Securities may be given at a
meeting of holders of Capital Securities convened for such purpose or pursuant
to written consent. The Property Trustee will cause a notice of any meeting at
which holders of Capital Securities are entitled to vote, or of any matter upon
which action by written consent of such holders is to be taken, to be given to
each holder of record of Capital Securities in the manner set forth in each
Trust Agreement.
 
     No vote or consent of the holders of Capital Securities will be required
for an Issuer Trust to redeem and cancel its Capital Securities in accordance
with the applicable Trust Agreement.
 
                                       24
<PAGE>   53
 
     Notwithstanding that holders of Capital Securities are entitled to vote or
consent under any of the circumstances described above, any of the Capital
Securities that are owned by the Corporation, the Issuer Trustees or any
affiliate of the Corporation or any Issuer Trustees, shall, for purposes of such
vote or consent, be treated as if they were not outstanding.
 
GLOBAL CAPITAL SECURITIES
 
     The Capital Securities of a series may be issued in whole or in part in the
form of one or more Global Capital Securities that will be deposited with, or on
behalf of, the Depositary, which unless otherwise indicated in the applicable
Prospectus Supplement for such series will be DTC. Global Capital Securities may
be issued only in fully registered form and in either temporary or permanent
form. Unless and until it is exchanged in whole or in part for the individual
Capital Securities represented thereby, a Global Capital Security may not be
transferred except as a whole by the Depositary for such Global Capital Security
to a nominee of such Depositary or by a nominee of such Depositary to such
Depositary or another nominee of such Depositary or by the Depositary or any
nominee to a successor Depositary or any nominee of such successor.
 
     The specific terms of the depositary arrangement with respect to a series
of Capital Securities will be described in the Prospectus Supplement relating to
such series. The Corporation anticipates that the following provisions will
generally apply to depositary arrangements.
 
     Upon the issuance of a Global Capital Security, and the deposit of such
Global Capital Security with or on behalf of the Depositary, the Depositary for
such Global Capital Security or its nominee will credit, on its book-entry
registration and transfer system, the respective aggregate Liquidation Amounts
of the individual Capital Securities represented by such Global Capital
Securities to the accounts of Participants, which may include Euroclear and
Cedel. Such accounts shall be designated by the dealers, underwriters or agents
with respect to such Capital Securities or by the Corporation if such Capital
Securities are offered and sold directly by the Corporation. Ownership of
beneficial interests in a Global Capital Security will be limited to
Participants or persons that may hold interests through Participants including
Euroclear and Cedel. Ownership of beneficial interests in such Global Capital
Security will be shown on, and the transfer of that ownership will be effected
only through, records maintained by the applicable Depositary or its nominee
(with respect to interests of Participants) and the records of Participants
(with respect to interests of persons who hold through Participants). The laws
of some states require that certain purchasers of securities take physical
delivery of such securities in definitive form. Such limits and such laws may
impair the ability to transfer beneficial interests in a Global Capital
Security.
 
     So long as the Depositary for a Global Capital Security, or its nominee, is
the registered owner of such Global Capital Security, such Depositary or such
nominee, as the case may be, will be considered the sole owner or holder of the
Capital Securities represented by such Global Capital Security for all purposes
under the Indenture governing such Capital Securities. Except as provided below,
owners of beneficial interests in a Global Capital Security will not be entitled
to have any of the individual Capital Securities of the series represented by
such Global Capital Security registered in their names, will not receive or be
entitled to receive physical delivery of any such Capital Securities of such
series in definitive form and will not be considered the owners or holders
thereof under the Indenture.
 
     Payments of principal of and premium, if any, and interest on individual
Capital Securities represented by a Global Capital Security registered in the
name of a Depositary or its nominee will be made to the Depositary or its
nominee, as the case may be, as the registered owner of the Global Capital
Security representing such Capital Securities. None of the Corporation, the
Property Trustee, any Paying Agent, or the Securities Registrar for such Capital
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 Capital Security representing such Capital Securities or
for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.
 
     The Corporation expects that the Depositary for a series of Capital
Securities or its nominee, upon receipt of any payment of Liquidation Amount,
Redemption Price, premium or Distributions in respect of a permanent Global
Capital Security representing any of such Capital Securities, immediately will
credit Participants' accounts with payments in amounts proportionate to their
respective beneficial interest in the aggregate Liquidation Amount of such
Global Capital Security for such Capital Securities as shown on the records of
such
 
                                       25
<PAGE>   54
 
Depositary or its nominee. The Corporation also expects that payments by
Participants to owners of beneficial interests in such Global Capital Security
held through such Participants will be governed by standing instructions and
customary practices, as is now the case with securities held for the accounts of
customers in bearer form or registered in "street name." Such payments will be
the responsibility of such Participants.
 
     Unless otherwise specified in the applicable Prospectus Supplement, if a
Depositary for a series of Capital Securities is at any time unwilling, unable
or ineligible to continue as depositary and a successor depositary is not
appointed by the Corporation within 90 days, the Issuer Trust will issue
individual Capital Securities of such series in exchange for the Global Capital
Security representing such series of Capital Securities. In addition, the Issuer
Trust may at any time and in its sole discretion, subject to any limitations
described in the Prospectus Supplement relating to such Capital Securities,
determine not to have any Capital Securities of such series represented by one
or more Global Capital Securities and, in such event, will issue individual
Capital Securities of such series in exchange for the Global Capital Security or
Securities representing such series of Capital Securities. Further, if the
Issuer Trust so specifies with respect to the Capital Securities of a series, an
owner of a beneficial interest in a Global Capital Security representing Capital
Securities of such series may, on terms acceptable to the Issuer Trust, the
Property Trustee and the Depositary for such Global Capital Security, receive
individual Capital Securities of such series in exchange for such beneficial
interests, subject to any limitations described in the Prospectus Supplement
relating to such Capital Securities. In any such instance, an owner of a
beneficial interest in a Global Capital Security will be entitled to physical
delivery of individual Capital Securities of the series represented by such
Global Capital Security equal in principal amount to such beneficial interest
and to have such Capital Securities registered in its name.
 
PAYMENT AND PAYING AGENCY
 
     Payments in respect of the Capital Securities shall be made to the
Depositary, which shall credit the relevant accounts at the Depositary on the
applicable Distribution Dates or, if any Issuer Trust's Capital Securities are
not held by the Depositary, such payments shall be made by check mailed to the
address of the holder entitled thereto as such address shall appear on the
securities register of the Trust Securities. Unless otherwise specified in the
applicable Prospectus Supplement, the paying agent (the "Paying Agent") will
initially be the Property Trustee and any co-paying agent chosen by the Property
Trustee and acceptable to the Administrators. The Paying Agent will be permitted
to resign as Paying Agent upon 30 days' written notice to the Property Trustee
and the Administrators. In the event that the Property Trustee shall no longer
be the Paying Agent, the Property Trustee shall appoint a successor (which shall
be a bank or trust company acceptable to the Administrators) to act as Paying
Agent.
 
REGISTRAR AND TRANSFER AGENT
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
Property Trustee will act as registrar and transfer agent for the Capital
Securities.
 
     Registration of transfers of Capital Securities will be effected without
charge by or on behalf of each Issuer Trust, but upon payment of any tax or
other governmental charges that may be imposed in connection with any transfer
or exchange. The Issuer Trusts will not be required to register or cause to be
registered the transfer of their Capital Securities after such Capital
Securities have been called for redemption.
 
INFORMATION CONCERNING THE PROPERTY TRUSTEE
 
     The Property Trustee, other than during the occurrence and continuance of
an Event of Default, undertakes to perform only such duties as are specifically
set forth in each Trust Agreement and, after such Event of Default, must
exercise the same degree of care and skill as a prudent person would exercise or
use in the conduct of his or her own affairs. Subject to this provision, the
Property Trustee is under no obligation to exercise any of the powers vested in
it by the applicable Trust Agreement at the request of any holder of Capital
Securities unless it is offered reasonable indemnity against the costs, expenses
and liabilities that might be incurred thereby. For information concerning the
relationships between Bankers Trust Company, the Property Trustee, and the
Corporation, see "Description of Junior Subordinated Debentures -- Information
Concerning the Debenture Trustee."
 
                                       26
<PAGE>   55
 
MISCELLANEOUS
 
     The Administrators are authorized and directed to conduct the affairs of
and to operate the Issuer Trusts in such a way that no Issuer Trust will be
deemed to be an "investment company" required to be registered under the
Investment Company Act or classified as a corporation for United States federal
income tax purposes and so that the Corresponding Junior Subordinated Debentures
will be treated as indebtedness of the Corporation for United States federal
income tax purposes. In this connection, the holders of Common Securities, the
Administrators and the Property Trustee are authorized to take any action, not
inconsistent with applicable law, the certificate of trust of each Issuer Trust
or each Trust Agreement, that the Property Trustee and the holders of Common
Securities determine in their discretion to be necessary or desirable for such
purposes, as long as such action does not materially adversely affect the
interests of the holders of the Related Capital Securities.
 
     Holders of the Capital Securities have no preemptive or similar rights.
 
     No Issuer Trust may borrow money or issue debt or mortgage or pledge any of
its assets.
 
GOVERNING LAW
 
     Each Trust Agreement will be governed by and construed in accordance with
the laws of the State of Delaware.
 
                              BOOK-ENTRY ISSUANCE
 
     DTC will act as securities depositary for all of the Capital Securities and
the Junior Subordinated Debentures, unless otherwise referred to in the
Prospectus Supplement relating to an offering of Capital Securities or Junior
Subordinated Debentures. The Capital Securities and the Junior Subordinated
Debentures will be issued only as fully-registered securities registered in the
name of Cede & Co. (DTC's nominee). One or more fully-registered global
certificates will be issued for the Capital Securities of each Issuer Trust and
the Junior Subordinated Debentures, representing in the aggregate the total
number of such Issuer Trust's Capital Securities or aggregate principal amount
of Junior Subordinated Debentures, respectively, and will be deposited with the
Property Trustee as custodian for DTC.
 
     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" with the meaning
of the New York Uniform Commercial Code, and a "clearing agency" registered
pursuant to the provisions of Section 17A of the Exchange Act. DTC holds
securities that its 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 custodial relationships with Direct
Participants, either directly or indirectly ("Indirect Participants"). The rules
applicable to DTC and its Participants are on file with the Commission.
 
     Purchases of Capital Securities or Junior Subordinated Debentures within
the DTC system must be made by or through Direct Participants, which will
receive a credit for the Capital Securities or Junior Subordinated Debentures on
DTC's records. The ownership interest of each actual purchaser of each Capital
Security and each Junior Subordinated Debenture ("Beneficial Owner") is in turn
to be recorded on the Direct and Indirect Participants' records, including
Euroclear and Cedel. Beneficial Owners will not receive written confirmation
from DTC of their purchases, but Beneficial Owners are expected to receive
written confirmations providing details of the transactions, as well as periodic
statements of their holdings, from the Direct or Indirect Participants through
which the Beneficial Owners purchased Capital Securities or Junior Subordinated
Debentures are to be accomplished by entries made on the books of Participants
acting on behalf of Beneficial Owners. Beneficial Owners will not receive
certificates representing their ownership interests in Capital Securities or
Junior
 
                                       27
<PAGE>   56
 
Subordinated Debentures, except in the event that use of the book-entry system
for the Capital Securities of such Issuer Trust or Junior Subordinated
Debentures is discontinued.
 
     Transfers between Participants will be effected in accordance with DTC's
procedures and will be settled in same-day funds. Transfers between participants
in Euroclear and Cedel will be effected in the ordinary way in accordance with
their respective rules and operating procedures.
 
     Cross-market transfers between Participants, on the one hand, and Euroclear
participants or Cedel participants, on the other hand, will be effected in DTC
in accordance with DTC's rules on behalf of Euroclear or Cedel, as the case may
be, by its respective depositary; however, such cross-market transactions will
require delivery of instructions to Euroclear or Cedel, as the case may be, by
the counterparty in such system in accordance with the rules and procedures and
within the established deadlines (Brussels time) of such system. Euroclear or
Cedel, as the case may be, will if the transaction meets its settlement
requirements, deliver instructions to its respective depositary to take actions
or effect final settlement on its behalf by delivering or receiving interests in
the Capital Securities or Junior Subordinated Debentures in DTC, and making or
receiving payment in accordance with normal procedures for same-day funds
settlement applicable to DTC. Euroclear participants and Cedel participants may
not deliver instructions directly to the depositaries for Euroclear or Cedel.
 
     Because of time zone differences, the securities account of a Euroclear or
Cedel participant purchasing an interest in a Capital Security or Junior
Subordinated Debenture from a Participant in DTC will be credited, and any such
crediting will be reported to the relevant Euroclear participant or Cedel
participant, during the securities settlement processing day (which must be a
business day for Euroclear and Cedel, as the case may be) immediately following
the DTC settlement date. Cash received in Euroclear or Cedel as a result of
sales of interests in a Capital Security or Junior Subordinated Debenture by or
through a Euroclear or Cedel participant to a Participant in DTC will be
received with value on the DTC settlement date but will be available in the
relevant Euroclear or Cedel cash account only as of the business day for
Euroclear or Cedel following the DTC settlement date.
 
     DTC has no knowledge of the actual Beneficial Owners of the Capital
Securities or Junior Subordinated Debentures; DTC's records reflect only the
identity of the Direct Participants to whose accounts such Capital Securities or
Junior Subordinated Debentures are credited, which may or may not be the
Beneficial Owners. The Participants will remain responsible for keeping account
of their holdings on behalf of their customers.
 
     Conveyance of notices and other communications by DCT to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners and the voting
rights of Direct Participants, Indirect Participants and 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.
 
     Redemption notices will be sent to Cede & Co. as the registered holder of
the Capital Securities or Junior Subordinated Debentures. If less than all of an
Issuer Trust's Capital Securities or the Junior Subordinated Debentures are
being redeemed, DTC's current practice is to determine by lot the amount of the
interest of each Direct Participant to be redeemed.
 
     Although voting with respect to the Capital Securities or the Junior
Subordinated Debentures is limited to the holders of record of the Capital
Securities or Junior Subordinated Debentures, in those instances in which a vote
is required, neither DTC nor Cede & Co. will itself consent or vote with respect
to Capital Securities or Junior Subordinated Debentures. Under its usual
procedures, DTC would mail an omnibus proxy (the "Omnibus Proxy") to the
relevant trustee as soon as possible after the record date. The Omnibus Proxy
assigns Cede & Co.'s consenting or voting rights to those Direct Participants to
whose accounts such Capital Securities or Junior Subordinated Debentures are
credited on the record date (identified in a listing attached to the Omnibus
Proxy).
 
     Distribution payments on the Capital Securities or the Junior Subordinated
Debentures will be made by the relevant trustee to DTC. DTC's practice is to
credit Direct Participants' accounts on the relevant payment date in accordance
with their respective holdings shown on DTC's records unless DTC has reason to
believe that it will not receive payments on such payment date. Payments by
Participants to Beneficial Owners will be governed by standing instructions and
customary practices and will be the responsibility of such Participant and not
of DTC, the relevant trustee, the Issuer Trust or the Corporation, subject to
any statutory or regulatory requirements as may be in effect from time to time.
Payment of Distributions to DTC is the responsibility of the relevant
 
                                       28
<PAGE>   57
 
trustee, disbursement of such payments to Direct Participants is the
responsibility of DTC, and disbursement of such payments to the Beneficial
Owners is the responsibility of Direct and Indirect Participants.
 
     DTC may discontinue providing its services as securities depositary with
respect to any of the Capital Securities or the Junior Subordinated Debentures
at any time by giving reasonable notice to the relevant trustee and the
Corporation. In the event that a successor securities depositary is not
obtained, definitive Capital Security or Junior Subordinated Debenture
certificates representing such Capital Securities or Junior Subordinated
Debentures are required to be printed and delivered. The Corporation, at its
option, may decide to discontinue use of the system of book-entry transfers
through DTC (or a successor depositary). After a Debenture Event of Default, the
holders of a majority in Liquidation Amount of Capital Securities or aggregate
principal amount of Junior Subordinated Debentures may determine to discontinue
the system of book-entry transfers through DTC. In any such event, definitive
certificates for such Capital Securities or Junior Subordinated Debentures will
be printed and delivered.
 
     The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that the Issuer Trusts and the Corporation
believe to be accurate, but the Issuer Trusts and the Corporation assume no
responsibility for the accuracy thereof. Neither the Issuer Trusts nor the
Corporation has any responsibility for the performance by DTC or its
Participants of their respective obligations as described herein or under the
rules and procedures governing their respective operations.
 
                           DESCRIPTION OF GUARANTEES
 
     A Guarantee will be executed and delivered by the Corporation concurrently
with the issuance by each Issuer Trust of its Capital Securities for the benefit
of the holders from time to time of such Capital Securities. Bankers Trust
Company will act as guarantee trustee ("Guarantee Trustee") under each Guarantee
for the purposes of compliance with the Trust Indenture Act and each Guarantee
will be qualified as an indenture under the Trust Indenture Act. This summary of
certain provisions of the Guarantees does not purport to be complete and is
subject to, and qualified in its entirety by reference to, all of the provisions
of each Guarantee, including the definitions therein of certain terms, and the
Trust Indenture Act, to each of which reference is hereby made. The form of the
Guarantee has been filed as an exhibit to the Registration Statement of which
this Prospectus forms a part. Reference in this summary to Capital Securities
means that Issuer Trust's Capital Securities to which a Guarantee relates. The
Guarantee Trustee will hold each Guarantee for the benefit of the holders of the
related Issuer Trust's Capital Securities.
 
GENERAL
 
     The Corporation will irrevocably agree to pay in full on a subordinated
basis, to the extent set forth herein, the Guarantee Payments (as defined below)
to the holders of the Capital Securities, as and when due, regardless of any
defense, right of set-off or counterclaim that the related Issuer Trust may have
or assert other than the defense of payment. The following payments with respect
to the Capital Securities, to the extent not paid by or on behalf of the related
Issuer Trust (the "Guarantee Payments"), will be subject to the Guarantee: (i)
any accumulated and unpaid Distributions required to be paid on such Capital
Securities, to the extent that such Issuer Trust has funds on hand available
therefor at such time, (ii) the Redemption Price with respect to any Capital
Securities called for redemption, to the extent that such Issuer Trust has funds
on hand available therefor at such time, and (iii) upon a voluntary or
involuntary dissolution of such Issuer Trust (unless the Corresponding Junior
Subordinated Debentures are distributed to holders of such Capital Securities in
exchange therefor), the lesser of (a) the aggregate of the Liquidation Amount
and all accumulated and unpaid Distributions to the date of payment, to the
extent that the Issuer Trust has funds on hand available therefor at such time
and (b) the amount of assets of such Issuer Trust remaining available for
distribution to holders of Capital Securities on liquidation of the Issuer
Trust. The Corporation's obligation to make a Guarantee Payment may be satisfied
by direct payment of the required amounts by the Corporation to the holders of
the applicable Capital Securities or by causing the Issuer Trust to pay such
amounts to such holders.
 
     Each Guarantee will be an irrevocable guarantee on a subordinated basis of
the related Issuer Trust's obligations under the Capital Securities, but will
apply only to the extent that such related Issuer Trust has funds sufficient to
make such payments, and is not a guarantee of collection.
 
                                       29
<PAGE>   58
 
     If the Corporation does not make payments on the Corresponding Junior
Subordinated Debentures held by the Issuer Trust, the Issuer Trust will not be
able to pay any amounts payable in respect of the Capital Securities and will
not have funds legally available therefor. Each Guarantee will rank subordinate
and junior in right of payment to all Senior Indebtedness of the Corporation.
See "-- Status of the Guarantees." Because the Corporation is a holding company,
the right of the Corporation to participate in any distribution of assets of any
subsidiary, upon such subsidiary's liquidation or reorganization or otherwise,
is subject to the prior claims of creditors of that subsidiary, except to the
extent the Corporation may itself be recognized as a creditor of that
subsidiary. Accordingly, the Corporation's obligations under the Guarantees will
be effectively subordinated to all existing and future liabilities of the
Corporation's subsidiaries, and claimants should look only to the assets of the
Corporation for payments thereunder. Except as otherwise provided in the
applicable Prospectus Supplement, the Guarantees do not limit the incurrence or
issuance of other secured or unsecured debt of the Corporation, including Senior
Indebtedness, whether under the Indenture, any other existing indenture or any
other indenture that the Corporation may enter into the future or otherwise.
 
     The Corporation has, through the applicable Guarantee, the applicable Trust
Agreement, the applicable series of Corresponding Junior Subordinated Debentures
and the Indenture, taken together, fully, irrevocably and unconditionally
guaranteed all of the Issuer Trust's obligations under the Capital Securities.
No single document standing alone or operating in conjunction with fewer than
all of the other documents constitutes such guarantee. It is only the combined
operation of these documents that has the effect of providing a full,
irrevocable and unconditional guarantee of the Issuer Trust's obligations under
the Capital Securities. See "Relationship Among the Capital Securities, the
Corresponding Junior Subordinated Debentures and the Guarantees."
 
STATUS OF THE GUARANTEES
 
     Each Guarantee will constitute an unsecured obligations of the Corporation
and will rank subordinate and junior in right of payment to all Senior
Indebtedness of the Corporation in the same manner as the Junior Subordinated
Debentures.
 
     Each Guarantee will rank pari passu with all other Guarantees issued by the
Corporation. Each Guarantee will constitute a guarantee of payment and not of
collection (i.e., the guaranteed party may institute a legal proceeding directly
against the guarantor to enforce its rights under the Guarantee without first
instituting a legal proceeding against any other person or entity). Each
Guarantee will be held by the Guarantee Trustee for the benefit of the holders
of the related Capital Securities. Each Guarantee will not be discharged except
by payment of the Guarantee Payments in full to the extent not paid by the
Issuer Trust or distribution to the holders of the Capital Securities of the
Corresponding Junior Subordinated Debentures. None of the Guarantees places a
limitation on the amount of additional Senior Indebtedness that may be incurred
by the Corporation. The Corporation expects from time to time to incur
additional indebtedness constituting Senior Indebtedness.
 
AMENDMENTS AND ASSIGNMENT
 
     Except with respect to any changes which do not materially adversely affect
the right of holders of the Related Capital Securities (in which case no vote
will be required), no Guarantee may be amended without the prior approval of the
holders of not less than a majority of the aggregate Liquidation Amount of such
outstanding Capital Securities. The manner of obtaining any such approval will
be as set forth under "Description of Capital Securities -- Voting Rights;
Amendment of Each Trust Agreement." All guarantees and agreements contained in
each Guarantee shall bind the successors, assigns, receivers, trustees and
representatives of the Corporation and shall inure to the benefit of the holders
of the Related Capital Securities then outstanding.
 
EVENTS OF DEFAULT
 
     An event of default under each Guarantee will occur upon the failure of the
Corporation to perform any of its payment or other obligations thereunder, or to
perform any non-payment obligation if such non-payment default remains
unremedied for 30 days. The holders of not less than a majority in aggregate
Liquidation Amount of the Related Capital Securities have the right to direct
the time, method and place of conducting any proceeding for any remedy available
to the Guarantee Trustee in respect of such Guarantee or to direct the exercise
of any trust or power conferred upon the Guarantee Trustee under such Guarantee.
 
                                       30
<PAGE>   59
 
     Any registered holder of the Capital Securities may institute a legal
proceeding directly against the Corporation to enforce its rights under such
Guarantee without first instituting a legal proceeding against the Issuer Trust,
the Guarantee Trustee or any other person or entity.
 
     The Corporation, as guarantor, is required to file annually with the
Guarantee Trustee a certificate as to whether or not the Corporation is in
compliance with all the conditions and covenants applicable to it under the
Guarantee.
 
INFORMATION CONCERNING THE GUARANTEE TRUSTEE
 
     The Guarantee Trustee, other than during the occurrence and continuance of
a default by the Corporation in performance of any Guarantee, undertakes to
perform only such duties as are specifically set forth in each Guarantee and,
after the occurrence of an event of default with respect to any Guarantee, must
exercise the same degree of care and skill as a prudent person would exercise or
use in the conduct of his or her own affairs. Subject to this provision, the
Guarantee Trustee is under no obligation to exercise any of the powers vested in
it by any Guarantee at the request of any holder of any Capital Securities
unless it is offered reasonable indemnity against the costs, expenses and
liabilities that might be incurred thereby. For information concerning the
relationship between Bankers Trust Company, the Guarantee Trustee, and the
Corporation, see "Description of Junior Subordinated Debentures -- Information
Concerning the Debenture Trustee."
 
TERMINATION OF THE GUARANTEE
 
     Each Guarantee will terminate and be of no further force and effect upon
full payment of the Redemption Price of the Related Capital Securities, upon
full payment of the amounts payable upon liquidation of the related Issuer Trust
or upon distribution of Corresponding Junior Subordinated Debentures to the
holders of the related Trust Securities in exchange therefor. Each Guarantee
will continue to be effective or will be reinstated, as the case may be, if at
any time any holder of the related Trust Securities must restore payment of any
sums paid under such Trust Securities or such Guarantee.
 
GOVERNING LAW
 
     Each Guarantee will be governed by and construed in accordance with the
laws of the State of New York.
 
          RELATIONSHIP AMONG THE CAPITAL SECURITIES, THE CORRESPONDING
               JUNIOR SUBORDINATED DEBENTURES AND THE GUARANTEES
 
FULL AND UNCONDITIONAL GUARANTEE
 
     Payments of Distributions and other amounts due on the Capital Securities
(to the extent the Issuer Trust has funds available for the payment of such
Distributions and other amounts) are irrevocably guaranteed by the Corporation
as and to the extent set forth under "Description of Guarantees." Taken
together, the Corporation's obligations under each series of Corresponding
Junior Subordinated Debentures, the Indenture, the related Trust Agreement and
the related Guarantee provide, in the aggregate, a full irrevocable and
unconditional guarantee of payments of Distributions and other amounts due on
the Related Capital Securities. No single document standing alone or operating
in conjunction with fewer than all of the other documents constitutes such
guarantee. It is only the combined operation of these documents that has the
effect of providing a full, irrevocable and unconditional guarantee of the
Issuer Trust's obligations under the Related Capital Securities. If and to the
extent that the Corporation does not make payments on any series of
Corresponding Junior Subordinated Debentures, such Issuer Trust will not pay
Distributions when the related Issuer Trust does not have sufficient funds to
pay such Distributions. In such event, the remedy of a holder of a series of
Capital Securities is to institute a legal proceeding directly against the
Corporation pursuant to the terms of the Indenture for enforcement of payment of
amounts equal to such Distributions to such holder.
 
     The obligations of the Corporation under the Indenture and each Guarantee
are subordinate and junior in right of payment to all Senior Indebtedness.
 
                                       31
<PAGE>   60
 
SUFFICIENCY OF PAYMENTS
 
     As long as payments are made when due on each series of Corresponding
Junior Subordinated Debentures, such payments will be sufficient to cover
Distributions and other payments distributable on the Related Capital
Securities, primarily because (i) the aggregate principal amount of each series
of Corresponding Junior Subordinated Debentures will be equal to the sum of the
aggregate stated Liquidation Amount of the Related Capital Securities and
related Common Securities; (ii) the interest rate and interest and other payment
dates on each series of Corresponding Junior Subordinated Debentures will match
the Distribution rate and Distribution and other payment dates for the Related
Capital Securities; (iii) the Corporation shall pay for all and any costs,
expenses and liabilities of such Issuer Trust except the Issuer Trust's
obligations to holders of the Trust Securities; and (iv) each Trust Agreement
further provides that the Issuer Trust will not engage in any activity that is
not consistent with the limited purposes of such Issuer Trust.
 
     Notwithstanding anything to the contrary in the Indenture, the Corporation
has the right to set-off any payment it is otherwise required to make thereunder
against and to the extent the Corporation has theretofore made, or is
concurrently on the date of such payment making, a payment under the related
Guarantee.
 
ENFORCEMENT RIGHTS OF HOLDERS OF CAPITAL SECURITIES
 
     A holder of any Related Capital Security may institute a legal proceeding
directly against the Corporation to enforce its rights under the related
Guarantee without first instituting a legal proceeding against the Guarantee
Trustee, the related Issuer Trust or any other person or entity. See
"Description of Guarantee."
 
     A default or event of default under any Senior Indebtedness of the
Corporation would not constitute a default or Event of Default in respect of the
Capital Securities. However, in the event of payment defaults under, or
acceleration of, Senior Indebtedness of the Corporation, the subordination
provisions of the Indenture provide that no payments may be made in respect of
the Corresponding Junior Subordinated Debentures until such Senior Indebtedness
has been paid in full or any payment default thereunder has been cured or
waived. Failure to make required payments on any series of Corresponding Junior
Subordinated Debentures would constitute an Event of Default under the
Indenture. See "Description of Junior Subordinated Debentures -- Subordination."
 
LIMITED PURPOSE OF ISSUER TRUSTS
 
     Each Issuer Trust's Capital Securities evidence preferred undivided
beneficial interests in the assets of the Issuer Trust, and each Issuer Trust
exists for the sole purpose of issuing its Capital Securities and Common
Securities and investing the proceeds thereof in Corresponding Junior
Subordinated Debentures. A principal difference between the rights of a holder
of a Capital Security and a holder of a Corresponding Junior Subordinated
Debenture is that a holder of a Corresponding Junior Subordinated Debenture is
entitled to receive from the Corporation payments on Corresponding Junior
Subordinated Debentures held, while a holder of Capital Securities is entitled
to receive Distributions or other amounts distributable with respect to the
Capital Securities from such Issuer Trust (or from the Corporation under the
applicable Guarantee) only if and to the extent such Issuer Trust has funds
available for the payment of such Distributions.
 
RIGHTS UPON TERMINATION
 
     Upon any voluntary or involuntary dissolution of an Issuer Trust, other
than any such dissolution involving the distribution of the Junior Subordinated
Debentures, involving the liquidation of the Corresponding Junior Subordinated
Debentures, after satisfaction of liabilities to creditors of the Issuer Trust
as required by applicable law, the holders of the Related Capital Securities
will be entitled to receive, out of the assets held by such Issuer Trust, the
Liquidation Distribution in cash. See "Description of Capital Securities --
Liquidation Distribution Upon Termination." Upon any voluntary or involuntary
liquidation or bankruptcy of the Corporation, the Issuer Trust, as registered
holder of the Corresponding Junior Subordinated Debentures, would be a
subordinated creditor of the Corporation, subordinated and junior in right of
payment to all Senior Indebtedness as set forth in the Indenture, but entitled
to receive payment in full of all amounts payable with respect to the Junior
Subordinated Debentures before any stockholders of the Corporation receive
payments or distributions. Since the Corporation is the guarantor under each
Guarantee and has agreed to pay for all costs, expenses and liabilities of each
Issuer Trust (other than the Issuer Trust's obligations to the holders of its
Trust Securities), the positions of a holder of such Capital Securities and a
holder of such Corresponding Junior Subordinated Debentures relative
                                       32

to other creditors and to stockholders of the Corporation in the event of
liquidation or bankruptcy of the Corporation are expected to be substantially
the same.
 
                   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 the Corporation. 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, the Corporation's
primary bank regulatory authority is 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, the Corporation 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
the Corporation of future changes in monetary and other policies of the Federal
Reserve are not predictable, as such changes also depend on economic conditions
and domestic and foreign governmental policies, among other factors.
 
     The Corporation is a legal entity separate and distinct from 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 the Corporation is a holding company, its rights
and the rights of its creditors and shareholders, including the holders of the
Trust 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 the Corporation may itself
be a creditor with recognized claims against the subsidiary.
 
     The Corporation 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 the Corporation's depository institution
subsidiaries may extend credit, pay dividends or otherwise supply funds to the
Corporation. For example, the approval of the OCC is required if total dividends
by a national bank in any calendar year exceed net profits 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 the Corporation'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 ratio 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
Corporation's ability to pay dividends.
 
     The U.S. federal bank regulatory authorities have each adopted risk-based
capital guidelines to which the Corporation and its insured depository
institution 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. 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
 
                                       33
<PAGE>   62
 
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 one-half (4%) must be "Tier 1"
capital. In addition, U.S. federal bank regulators have established leverage
ratio (Tier 1 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, taking into
consideration concentration of credit risk and the risk arising from
non-traditional activities, as well as an institution's ability to manage these
risks. The capital guidelines also provide that an institution's exposure to a
decline in the economic value of its capital due to changes in interest rates be
considered by the agencies as a factor in evaluating a bank's capital adequacy.
The Federal Reserve also has recently issued additional capital guidelines for
bank holding companies that engage in certain trading activities.
 
     The federal banking agencies possess broad powers to take corrective action
as deemed appropriate for an insured depository institution and its holding
company. The extent of these powers depends upon whether the institution in
question is considered "well capitalized," "adequately capitalized,"
"undercapitalized," "significantly undercapitalized" or "critically
undercapitalized," as defined by the law. 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 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 broker deposits without
prior regulatory approval and only an "adequately capitalized" depository
institution may accept brokered deposits with prior regulatory approval. At
March 31, 1998, 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. However, based on
legislation enacted in 1996, the FDIC also assesses insured institutions an
additional premium based on deposit levels to cover certain bonds issued by a
government entity. 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, or for
any assistance provided by the FDIC to a commonly controlled insured depository
institution in danger of default. 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
 
                                       34
<PAGE>   63
 
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 December 31, 1997 merger of PNC Bank, National
Association and its banking affiliates located in Kentucky, Indiana and Ohio.
Competition may increase as banks branch across state lines and enter new
markets.
 
                              PLAN OF DISTRIBUTION
 
     The Junior Subordinated Debentures or the Capital Securities may be sold in
a public offering to or through underwriters or dealers designated from time to
time. The Corporation and each Issuer Trust may sell its Junior Subordinated
Debentures and Capital Securities, respectively, as soon as practicable after
effectiveness of the Registration Statement of which this Prospectus forms a
part. The names of any underwriters or dealers involved in the sale of the
Junior Subordinated Debentures or Capital Securities in respect of which this
Prospectus is delivered, the amount or number of Junior Subordinated Debentures
and Capital Securities to be purchased by any such underwriters and any
applicable commissions or discounts will be set forth in the applicable
Prospectus Supplement.
 
     Underwriters may offer and sell Junior Subordinated Debentures or Capital
Securities at a fixed price or prices, which may be changed, or from time to
time at market prices prevailing at the time of sale, at prices related to such
prevailing market prices or at negotiated prices. In connection with the sale of
Capital Securities, underwriters may be deemed to have received compensation
from the Corporation and/or the applicable Issuer Trust in the form of
underwriting discounts or commissions and may also receive commissions.
Underwriters may sell Junior Subordinated Debentures or Capital Securities to or
through dealers, and such dealers may receive compensation in the form of
discounts, concessions or commissions from the underwriters.
 
     Any underwriting compensation paid by the Corporation and/or the applicable
Issuer Trust to underwriters in connection with the offering of Junior
Subordinated Debentures or Capital Securities, and any discounts, concessions or
commissions allowed by such underwriters to participating dealers, will be
described in an accompanying Prospectus Supplement. Underwriters and dealers
participating in the distribution of Junior Subordinated Debentures or Capital
Securities may be deemed to be underwriters, and any discounts and commissions
received by them and any profit realized by them on resale of such Junior
Subordinated Debentures or Capital Securities may be deemed to be underwriting
discounts and commissions, under the Securities Act. Underwriters and dealers
may be entitled, under agreement with the Corporation and the applicable Issuer
Trust, to indemnification against and contribution toward certain civil
liabilities, including liabilities under the Securities Act, and to
reimbursement by the Corporation for certain expenses.
 
     In connection with the offering of the Capital Securities of any Issuer
Trust, such Issuer Trust may grant to the underwriters an option to purchase
additional Capital Securities to cover over-allotments, if any, at the initial
public offering price (with an additional underwriting commission), as may be
set forth in the accompanying Prospectus Supplement. If such Issuer Trust grants
any over-allotment option, the terms of such over-allotment option will be set
forth in the Prospectus Supplement for such Capital Securities.
 
     Underwriters and dealers may engage in transactions with, or perform
services for, the Corporation and/or the applicable Issuer Trust and/or any of
their affiliates in the ordinary course of business.
 
     The Junior Subordinated Debentures and the Capital Securities will be new
issues of securities and will have no established trading market. Any
underwriters to whom Junior Subordinated Debentures or Capital Securities are
sold for public offering and sale may make a market in such Junior Subordinated
Debentures and Capital Securities, but such underwriters will not be obligated
to do so and may discontinue any market making at any time without notice. Such
Junior Subordinated Debentures or Capital Securities may or may not be listed on
 
                                       35
<PAGE>   64
 
a national securities exchange or the Nasdaq National Market. No assurance can
be given as to the liquidity of or the existence of trading markets for any
Junior Subordinated Debentures or Capital Securities.
 
                              ACCOUNTING TREATMENT
 
     For financial reporting purposes, each Issuer Trust will be treated as a
subsidiary of the Corporation and, accordingly, the accounts of the Issuer Trust
will be included in the consolidated financial statements of the Corporation.
Capital Securities will be included in the consolidated balance sheets of the
Corporation and appropriate disclosures about Capital Securities, Guarantees and
Junior Subordinated Debentures will be included in the notes to the consolidated
financial statements of the Corporation. For financial reporting purposes,
Distributions on Capital Securities will be recorded in the consolidated
statements of income of the Corporation.
 
                                 LEGAL MATTERS
 
     Unless otherwise indicated in the applicable Prospectus Supplement, certain
legal matters will be passed upon for the Corporation by John F. Fulgoney,
Senior Counsel to the Corporation, and for the Issuer Trusts by Richards, Layton
